It occurs in up to 75% of patients with symptomatic extruded lumbar discs. The Atlasprofilax method favors osteo-musculo-articular rehabilitation processes, mainly impacting on 2 levels: the first is the bone anatomy of the atlanto-occipital joint, and the second is the fasciae located in the cervical region. CASE REPORT A 42-year-old male patient diagnosed by MRI with dehydration of L2-L3 to L5-S1 intervertebral discs, disc bulging at L2-L3 and L3-L4, and disc extrusion at L4-L5, received a one-time neuromuscular treatment, called the Atlasprofilax method, to the suboccipital region. In a repeat MRI 6 months later, the disc extrusion at L4-L5 was totally resorbed and improvement in the L3-L4 and L4-L5 disc bulges was seen. The patient's symptoms prior to the Atlasprofilax treatment included bilateral trapezius pain, right brachialgia, constant chronic low back pain, right sciatica, gait claudication, and paresthesia and dysesthesias in the lower limbs with associated pain and numbness in the calves. These symptoms were ameliorated after the treatment. The sciatica disappeared 1 week after the treatment and did not recur. In a follow-up 5 years later, the remaining symptoms had improved even further. CONCLUSIONS We propose that alterations of the cervical musculature and deep fascia could predispose to the development of lumbar disc abnormalities. We therefore also propose that improvements in this patient, both in symptoms and in imaging findings, are due to a reduction of the asymmetric distribution of forces and elastic loading as a result of the Atlasprofilax treatment." }, { "id": "Neurology_Adams_1600", "title": "Neurology_Adams", "score": 0.009639953542392568, "content": "The pain of herniated intervertebral disc varies in severity from a mild aching discomfort to severe knife-like stabs that radiate the length of the leg and are superimposed on a constant intense ache.

We previously validated a combined dual fluoroscopic and magnetic resonance imaging system to investigate in vivo lumbar kinematics. The purpose of the present study was to characterize mechanical dysfunction among patients with confirmed discogenic low back pain, relative to asymptomatic controls without degenerative disc disease, by quantifying abnormal vertebral motion. Ten subjects were recruited for the present study. All patients had discogenic low back pain confirmed clinically and radiographically at L4-L5 and L5-S1. Motions were reproduced with use of the combined imaging technique during flexion-extension, left-to-right bending, and left-to-right twisting movements. From local coordinate systems at the end plates, relative motions of the cephalad vertebrae with respect to caudad vertebrae were calculated at each of the segments from L2 to S1. Range of motion of the primary rotations and coupled translations and rotations were determined. During all three movements, the greatest range of motion was observed at L3-L4. L3-L4 had significantly greater motion than L2-L3 with left-right bending and left-right twisting movements (p < 0.05). The least motion occurred at L5-S1 for all movements; the motion at this level was significantly smaller than that at L3-L4 (p < 0.05). Range of motion during left-right bending and left-right twisting at L3-L4 was significantly larger in the degenerative disc disease group than in the normal group.

It is well known that the pain is produced by the increased tension of the affected root. However, the patient's response to the pain evoked by the straight leg raising test is not uniform. In some patients the leg is raised beyond the straight leg raising positive angle without resistance and some young patients show the tight hamstrings phenomenon. To elucidate these phenomena, the muscle action of erector spinae, gluteus maximus and biceps femoris evoked by this test was studied electromyographically. The results are as follows: 1) The muscle action patterns in the patients of disc herniation which are not observed in normal group are classified into four groups, namely LGB type (erector spinae, gluteus maximus and biceps femoris act), GB type (gluteus maximus and biceps femoris act), G type (gluteus maximus only acts), B type (biceps femoris only act). These abnormal muscle actions disappear under general anesthesia and are different from the actions which are recorded when the patients resist passive straight leg raising intentionally. 2) In the case of L4-5 intervertebral disc herniation mainly gluteus maximus acts as the resisting force against the passive straight leg raising. On the other hand, biceps femoris acts mainly in the case of L5-S1 disc herniation. 3) The group of younger age and less degenerated disc shows more resistance against straight leg raising and records the action potential of resisting muscles in earlier stage of the leg raising test." }, { "id": "article-29356_9", "title": "Spinal Stenosis -- History and Physical", "score": 0.0095547829987664, "content": "Stenosis in the lumbar spine can lead to neurogenic claudication, myeloradiculopathy symptoms, sensory disturbances, motor weakness, and pathologic reflexes.

The duration of renal disease was 116.0+/-60.5 months and the duration of follow-up post biopsy was 100.2+/-38.1 months. The pathological diagnosis was: IgA nephropathy (21 cases), focal glomerulosclerosis (9 cases), mesangial proliferative glomerulonephritis (8 cases), membranous glomerulonephritis (2 cases) and acute glomerulonephritis (1 case). At the end of follow-up, 8 cases (19.5%) had a certain degree of renal insufficiency including 2 (4.9%) in end-stage renal disease. The other cases were either in complete remission (6 cases) or stable condition (27 cases) with persistent microscopic hematuria and normal renal function. The long-term outcome was not correlated with any of the following parameters: age, sex, disease duration, serum creatinine at presentation, daily protein loss at presentation, degree of glomerular change and degree of interstitial inflammatory cell infiltration. However, a poor long-term outcome was correlated with tubular atrophy (p &lt; 0.05) and interstitial fibrosis (p &lt; 0.05). We conclude that a minimal urinary abnormality with normal renal function at presentation does not necessarily imply a favorable long-term outcome in certain patients.

We retrospectively reviewed all renal biopsies performed at our institution between 1986 and 2002 and identified patients with diagnoses consistent with primary glomerulopathy (PG), which included: minimal-change disease (MCD), idiopathic focal segmental glomerulosclerosis (FSGS), membranous nephropathy (MGN), IgA nephropathy (IgA), membrano-proliferative glomerulonephritis (MPGN) and mesangioproliferative glomerulonephritis. Patients with possible secondary causes for their renal disease were excluded. Clinical data at the time of biopsy and follow-up data were collected and analyzed. During the period from January 1986-December 2002, 299 renal biopsies were performed and 132 patients were diagnosed with PG.

Case Report. A 19-year old man with no medical history presented to the Emergency Department with a 20-day history of anasarca and frothy urine, BUN 68 mg/dL, Cr 2.3 mg/dL, urinalysis 3+ RBCs, 3+ protein, and urine protein : creatinine ratio 6.4. Renal biopsy revealed hypertrophic podocytes on light microscopy, podocyte foot process effacement on electron microscopy, and immunofluorescent mesangial staining for IgA. The patient was started on prednisone and exhibited dramatic improvement. Discussion. MCD typically has an overwhelming improvement with glucocorticoids, while the resolution of IgA nephropathy is rare. Our patient presented with MCD with the uncharacteristic finding of hematuria. Given the improvement with glucocorticoids, we raise the question of whether there is a shared pathophysiologic component of these two distinct clinical diseases that represents a clinical variant.

In addition, the entire retina is globally affected, and a cherry-red spot may appear in the macula. In this case the lesions are totally different. They describe hard exudates, deep hemorrhages and localized neurosensory retinal detachment. All this in the macula. These are the characteristic findings of neovascular (or exudative) AMD. As a clue, in the other eye there are abundant soft drusen. Drusen are the typical findings of AMD. So he has AMD in both eyes and in the right eye it has recently become complicated by the appearance of neovascularization.
An 84-year-old woman presents with loss of vision in the left eye of 4 days of evolution accompanied by metamorphopsia. The macula shows abundant hard exudates, two small deep hemorrhages and a localized neurosensory retinal detachment. In the contralateral eye there are abundant soft drusen. Given this picture, which of the following diagnoses do you think is the most likely?

Finally, the author emphasizes the need to consider this rare complication of drusen of the optic disk, especially in young patients with no systemic pathology who present this ophthalmoscopic picture, in order to avoid useless, time consuming tests and ineffective therapies." }, { "id": "wiki20220301en029_81277", "title": "Macular degeneration", "score": 0.009433962264150943, "content": "AMD-like pathology begins with small yellow deposits (drusen) in the macula, between the retinal pigment epithelium and the underlying choroid. Most people with these early changes (referred to as age-related maculopathy) still have good vision. People with drusen may or may not develop AMD. In fact, the majority of people over age 60 have drusen with no adverse effects. The risk of developing symptoms is higher when the drusen are large and numerous, and associated with the disturbance in the pigmented cell layer under the macula. Large and soft drusen are thought to be related to elevated cholesterol deposits. Early AMD Early AMD is diagnosed based on the presence of medium-sized drusen, about the width of an average human hair. Early AMD is usually asymptomatic. Intermediate AMD Intermediate AMD is diagnosed by large drusen and/or any retinal pigment abnormalities. Intermediate AMD may cause some vision loss, but, like early AMD, it is usually asymptomatic." }, { "id": "pubmed23n0482_8803", "title": "[Acute posterior multifocal epitheliopathy: case report].", "score": 0.009433962264150943, "content": "To present an atypical course of acute posterior multifocal placoid epitheliopathy. 59 years-old diabetic man was seen at emergency because of a few days history of blurred vision in his right eye. Ophthalmologic examination revealed patches of blurred margine, multiple, yellowish lesions 1-2 dd in the fundus in both eyes. There were also lesions typical for non proliferative diabetic retinopathy like microaneurysms, dot and blot intraretinal hemorrhages and hard exudates. Optic discs and blood vessels were normal. We found peripheral drusen extending from the equator to the ora serata in both eyes. During 8 months of observation, we performed three times ophthalmologic examination, fluorescein and indocyanine green angiographies, USG A and B. No treatment was given. There is disagreement about the site of origin of placoid lesions, etiology and pathogenesis in acute posterior multifocal placoid epitheliopathy. In our report we agree with thesis, that the choriocapillaris are the primary site of the break.

At the ocular level, AHT produces lesions in the retina, the choroids and optic nerve head; this can include a wide range of lesions, from slight vascular narrowing to severe visual loss due to ischaemic optical neuropathy. The primary response of the retinal arteries to systemic arterial hypertension is vascular narrowing and the manifestations that appear at the back of the eye in hypertensive retinopathy are diffuse or focal vasoconstriction, extravasation due to increased vascular permeability and arteriosclerosis with swelling of the wall of the vessels. These three entities are responsible for the appearance of different lesions that characterise the stages of the retinal disease, which are: arteriovenous crossings, hard and cotton-like exudates, thrombosis, embolisms, haemorrhages in the retinal parenchyma, vitreous detachment from the retina, papilla edema and ischaemic optical neuropathy in the more severe cases, such as in case malign arterial hypertension." }, { "id": "pubmed23n0852_20196", "title": "Multimodal imaging findings in a case of severe Central Serous Chorioretinopathy in an uncomplicated pregnancy.", "score": 0.009259259259259259, "content": "Central Serous Chorioretinopathy (CSC) has been previously reported as an infrequent complication of pregnancy that usually resolves spontaneously after delivery, with minimal or no sequel.

A 45-year-old woman comes to the clinic referred from surgery with the diagnosis of a neuroendocrine tumor diagnosed after partial pancreatectomy for a 2-cm tumor in the tail of the pancreas. The tumor had been detected by chance in an abdominal CT scan requested to complete the study of a simple hepatic cyst. On questioning the patient, the history of irregular menstruation, amenorrhea for the last 6 months, and repeated renal colic since she was 20 years old, for which she has required lithotripsy on several occasions, stand out. She also has a family history of renoureteral colic. What is her suspected diagnosis?

A 57-year-old woman consulted a clinic complaining of melena, intermittent abdominal pain, diarrhea, and vomiting which had persisted for about 3 years. Six months before her presentation, she underwent segmental resection of the jejunum for acute peritonitis due to the spontaneous jejunal perforation.

On computed tomography (CT), a hypervascular tumor of 23 mm in the segment 5 (S5) region of the liver was visualized. A selective arterial secretagogue injection test (SASI test) was performed twice. The first SASI test revealed that the hepatic tumor was a gastrinoma, and there was no gastrinoma in the duodeno-pancreatic region. Additionally, somatostatin receptor scintigraphy only visualized the tumor in the liver. However, the second SASI test, which was performed during the administration of a proton pump inhibitor and a somatostatin analog (octreotide acetate), revealed that there may have been gastrinomas existing not only in the liver but also in the upper part of the duodenum or the head of the pancreas. Duodenal endoscopy revealed multiple submucosal tumors in the first and the second portion of the duodenum, although a pathological examination of biopsied specimens obtained from the duodenal lesions was negative for malignant cells. Multiple endocrine neoplasia type 1 (MEN1) was excluded from her family history, and serum levels of both intact parathyroid hormone (iPTH) and calcium were within normal ranges.

Two existing syndromes, MEN1 and MEN2 (2A, 2B), in literature is also mentioned MEN4, are associated also with other non-endocrine disorders. MEN1 (Wermer syndrome) affects the pituitary, parathyroid, and pancreatic area. 95 % of patients show very early manifestation of hyperparathyroidism, often before 40 years of age. Multiple adenomas gradually involve all four parathyroid glands. The first clinical sign of MEN1 includes recurrent nephrolithiasis. The second most frequent manifestation of MEN1 is pancreatic area (pancreas, stomach and duodenum), again multiple malignancies of varying degree which can metastasize. Most often gastrinomas and insulinomas are involved. Pituitary adenomas occur in about one third of MEN1 patients and tend to be larger and less responsive to treatment. Tumors appearing most often are prolactinomas, tumors producing growth hormone, or afunctional adenomas. The other endocrine tumors include carcinoids and adrenal lesions.

Sixteen patients with genetically confirmed multiple endocrine neoplasia type 1 (MEN 1) and Zollinger-Ellison syndrome (ZES) underwent resection of both gastrinomas and duodenopancreatic neuroendocrine tumors (NETs) between 1991 and 2009. For localization of gastrinoma, selective arterial secretagogue injection test (SASI test) with secretin or calcium solution was performed as well as somatostatin receptor scintigraphy (SRS) and other imaging methods such as computed tomography (CT) or magnetic resonance imaging (MRI). The modus of surgery for gastrinoma has been changed over time, searching for the optimal surgery: pancreaticoduodenectomy (PD) was first performed guided by localization with the SAST test, then local resection of duodenal gastrinomas with dissection of regional lymph nodes (LR), and recently pancreas-preserving total duodenectomy (PPTD) has been performed for multiple duodenal gastrinomas. Among various types of preoperative localizing methods for gastrinoma, the SASI test was the most useful method. Imaging methods such as SRS or CT made it essentially impossible to differentiate functioning gastrinoma among various kinds of NETs. However, recent imaging methods including SRS or CT were useful for detecting both distant metastases and ectopic NETs; therefore they are indispensable for staging of NETs. Biochemical cure of gastrinoma was achieved in 14 of 16 patients (87.5%); that is, 100% in 3 patients who underwent PD, 100% in 6 patients who underwent LR (although in 2 patients (33.3%) second LR was performed for recurrence of duodenal gastrinoma), and 71.4% in 7 patients who underwent PPTD.

Therapeutic management depends on the patient's general condition and on the severity of the intraperitoneal infection, assessed according to Hinchey's 4-stage classification. For Hinchey stages I and II (pericolic or pelvic abscess), radiologically guided puncture-drainage is an effective treatment, combined with antibiotic therapy. Emergency surgery is only indicated if this drainage fails. Two to three months later, elective prophylactic sigmoidectomy, by laparoscopy, is indicated. In stage III or IV diverticulitis (generalized purulent or fecal peritonitis), the surgical treatment of reference is a Hartmann procedure (sigmoidectomy and left iliac colostomy with closure of the rectal stump). But because of burden of the procedure and the risk of failing to re-establish gastrointestinal continuity, it is preferable, if local conditions allow, to propose resection-anastomosis with a temporary protective stoma. Prophylactic sigmoidectomy is controversial. It is indicated regardless of the number of episodes and regardless of age in patients at high risk of recurrence, that is, those with a complicated clinical form or radiologic signs of severity. There is no consensus for patients aged younger than 75 years with a first uncomplicated episode, for whom the risk of recurrence is also elevated. Finally, for patients older than 50 years with an uncomplicated episode on CT, the role of prophylactic surgery, even after 2 or 3 episodes, has not been demonstrated, because of the very low risk (&lt;5%) of subsequent complications.

To improve the quality of patient care, a guideline for diagnosis and treatment of diverticulitis is needed. A multidisciplinary working group, representing experts of relevant specialties, was involved in the guideline development. A systematic literature search was conducted to collect scientific evidence on epidemiology, classification, diagnostics and treatment of diverticulitis. Literature was assessed using the classification system according to an evidence-based guideline development method, and levels of evidence of the conclusions were assigned to each topic. Final recommendations were given, taking into account the level of evidence of the conclusions and other relevant considerations such as patient preferences, costs and availability of facilities. The natural history of diverticulitis is usually mild and treatment is mostly conservative. Although younger patients have a higher risk of recurrent disease, a higher risk of complications compared to older patients was not found. In general, the clinical diagnosis of ACD is not accurate enough and therefore imaging is indicated. The triad of pain in the lower left abdomen on physical examination, the absence of vomiting and a C-reactive protein &gt;50 mg/l has a high predictive value to diagnose ACD. If this triad is present and there are no signs of complicated disease, patients may be withheld from further imaging. If imaging is indicated, conditional computed tomography, only after a negative or inconclusive ultrasound, gives the best results. There is no indication for routine endoscopic examination after an episode of diverticulitis. There is no evidence for the routine administration of antibiotics in patients with clinically mild uncomplicated diverticulitis. Treatment of pericolic or pelvic abscesses can initially be treated with antibiotic therapy or combined with percutaneous drainage. If this treatment fails, surgical drainage is required. Patients with a perforated ACD resulting in peritonitis should undergo an emergency operation. There is an ongoing debate about the optimal surgical strategy. Scientific evidence is scarce for some aspects of ACD treatment (e.g. natural history of ACD, ACD in special patient groups, prevention of ACD, treatment of uncomplicated ACD and medical treatment of recurrent ACD), leading to treatment being guided by the surgeon's personal preference. Other aspects of the management of patients with ACD have been more thoroughly researched (e.g. imaging techniques, treatment of complicated ACD and elective surgery of ACD). This guideline of the diagnostics and treatment of ACD can be used as a reference for clinicians who treat patients with ACD." }, { "id": "pubmed23n0945_24632", "title": "[Diverticulosis and diverticulitis of the vermiform appendix.

In this study we present the clinicopathology, diagnosis and therapy of the disease with a review of the literature. A 65-year-old woman presented to the emergency department with a 48-hour history of intermittent pain in the right iliac fossa. Abdominal ultrasound raised the possibility of acute appendicitis but because of the relative asymptomatic state of the patient, the lack of fever and rebound tenderness we started observation. After 2 days with episodic abdominal pain, the patient was taken to the operating theatre for laparoscopic exploration. Intraoperatively, multiple diverticula were noted on the appendix and appendectomy was performed. Histopathological examination revealed diverticulosis and inflammation of the appendiceal wall.

CT established that three patients (5 percent) were hospitalized with an incorrect clinical diagnosis. Thirty-seven patients (62.7 percent) were identified as having uncomplicated acute diverticulitis. These patients were all treated successfully with nonsurgical therapies and were discharged in an average of 6.8 days. In the remaining 19 patients (32.2 percent), CT revealed complicated acute diverticulitis by identifying abscess, fistula, peritonitis, or obstruction. Eleven of these 19 patients required urgent surgery or CT-guided percutaneous drainage of an abscess. The four patients whose abscesses were drained percutaneously responded favorably and underwent an elective single-stage resection. The average hospital stay for patients with complicated diverticulitis was 13.6 days. Computed tomography is a useful aid in the initial management of patients with acute diverticulitis. It is a noninvasive test that recognizes and stratifies patients according to the severity of their disease.

Currently, the main focus of surgical treatment concepts is on controlling the emergency situation triggered by acute complicated sigmoid diverticulitis through interventional and minimally invasive measures. This article presents the current data and recommendations on differentiated treatment of acute complicated sigmoid diverticulitis, which are also summarized in a decision tree. In general, resection of the diverticular sigmoid is needed to treat acute complicated sigmoid diverticulitis, because without resection the recurrence rate is too high at 40%. Since the morbidity and mortality rates associated with emergency resection are extremely high, resulting in the creation of a stoma, efforts are made to control the acute situation through interventional and laparoscopic measures. Therefore, pericolic and pelvic abscesses (Hinchey stages I, II) are eliminated through percutaneous or laparoscopic drainage. Likewise, laparoscopic lavage and drainage are performed for purulent and feculent peritonitis (Hinchey stages III, IV). After elimination of the acute septic situation, interval elective sigmoid resection is conducted. If emergency resection cannot be avoided, it is performed, while taking account of the patient's overall condition, with primary anastomosis and a protective stoma or as discontinuity resection using Hartmann's procedure.

In a paper including a larger number of patients published in 1992, W. B. Schwerk demonstrated a high sensitivity and specificity. The detection of diverticulitis was the final entry into the chapter of acute abdominal sonography, after the diagnosis of gastrointestinal perforation, acute appendicitis and ureterolithiasis had been achieved with high reliability. Until then, diverticulitis was a classic surgical disease and a contrast enema with water-soluble contrast medium the diagnostic method of choice. Invariably, the radiologist added the well known comment: Cancer of the sigmoid colon cannot be excluded with certainty. What has changed in the 12 years after Schwerk's publication? Many internists practising sonography have discovered the sonographic diagnosis of this condition and, depending on the severity, treat the less complicated cases with intravenous antibiotics and parental nutrition or with oral antibiotics and low-ballast diet. Soon, abscesses were healed with sonographically guided aspiration and drainage. For a long time, the older generation of surgeons stayed with contrast enemas and prolonged parenteral therapy and, in case of complications, surgical interventions, though surgeons early recognized the diagnostic contribution of sonography. Influenced by radiologists and the Anglo-American literature, surgeons increasingly used computed tomography (CT) as standard method for the initial diagnostic work-up for the last five to eight years. A physician dedicated to gastrointestinal sonography cannot accept this approach, in particular, since sonography is easy and reliable, provides a reasonable differential diagnosis and was found to help the surgeons. An exception is the deep-seated diverticulitis in the sometimes barely accessible distal sigmoid colon. Furthermore, an experienced clinician will anyhow proceed to CT in any unexplained discrepancy between clinical and sonographic findings. It reflects the high value given to sonography if our surgical colleagues use this diagnostic method in the primary diagnosis of acute diverticulitis and achieve results that are as good as the results of the expensive and by all criteria more elaborate CT. The extended application of ultrasound for the omentum and in necrotic epiploic appendagitis should be mentioned here as well. Altogether, CT can be easily refrained from in 80 % to 90 % of cases with suspected diverticulitis. In view of the DRG era, this is an important argument, and emphasizes the economic role of sonography, the necessity of correct coding of sonographic procedures and the need of more sonographic training. Only quality will increase the acceptance of sonography as diagnostic tool as repeatedly demanded and presented in this journal. If this fails, it is highly likely that the diagnostic potential of sonography will remain unexploited or, under the best of circumstances, rediscovered after a 5-year expiration date in a new literature search in 10 years." }, { "id": "pubmed23n0258_15730", "title": "[Radiological and endoscopic diagnosis of sigmoid diverticulitis].", "score": 0.013656633221850612, "content": "In emergency, the most commonly used examination, other than plain radiographs of the abdomen, is the water-soluble contrast enema (Gastrografin).

Ultrasonography may be a useful emergency procedure to secure a hesitating diagnosis in a patient with a febrile abdominal pain or with a abdominal-pelvic mass, especially in women. Colonoscopy and barium enema are both usually contra-indicated in the acute setting of diverticulitis because of their potential hazards. On the other hand, after resolution of the acute event, these tests may allow to rule out carcinoma or associated adenomas (which coexist in more than 15% of the patients). Endoscopic control appears more especially important as initial accurate diagnosis in sometimes impossible to assess between adenocarcinoma and diverticulitis. CT scan has found an increasing place in both diagnosis and evaluation of infectious complications of diverticular disease. It is most recommended to assess the diagnosis of severe episodes, failing to clearly improve after medical treatment, and most particularly when an abscess in suspected.

Special considerations must also be made for patients with a high surgical risk, such as immunosuppressed ones. The recommendations to perform surgery after two episodes of uncomplicated diverticulitis have been re-evaluated and the belief that new episodes may be complicated and associated with high morbidity and mortality has been rejected, since the clinical manifestations of this disease are usually defined by the first attack. In complicated cases, more patients can be treated with resection and primary anastomosis with or without an associated stoma, whose reversal rate is much higher than that of a Hartmann's procedure.

This systematic review attempts to assess the role of prophylactic left colonic resection, after episodes of uncomplicated acute diverticulitis treated either conservatively with antibiotics and/or other supportive measures. A systematic search was performed using Medline, Embase, Ovid, and Cochrane databases for studies reporting on the treatment of acute uncomplicated diverticulitis (Hinchey I). The main endpoint was treatment failure, defined as persistent/recurrent symptoms or need for readmission and/or reintervention. Secondary endpoints were the immediate postoperative outcomes. In total, 24 studies with 2855 patients were included in the analysis. Intra- and postoperative complications rate were 5% and 16%, respectively. Anastomotic leak was 1.3% and emergency reoperation was 2.4%. Long-term symptomatic resolve was reported at 91%. Persistent or recurrent symptoms were observed in 5.4% of cases. Meta-analysis showed no significant difference in recurrence rates between surgical and conservative management. Elective surgery to prevent recurrent diverticulitis is not recommended, irrespective of the number of previous episodes. Generally, elective sigmoidectomy should not be recommended to patients with ongoing atypical lower abdominal symptoms after acute diverticulitis, but should aim primarily at improving quality of life.

The presence of colonic diverticula, which is considered to be a mucosal herniation through the intestinal muscle wall, is inversely correlated to the intake of dietary fibre. Other factors in the genesis of diverticular disease may be physical inactivity, obesity, and use of NSAIDs or acetaminophen. Diverticulosis is most common in Western countries with a prevalence of 5% in the population aged 30-39 years and 60% in the part of the population &gt; 80 years. The incidence of hospitalization for acute diverticulitis is 71/100,000 and the incidence of complicated diverticulitis is 3.5-4/100,000. Acute diverticulitis is conveniently divided into uncomplicated and complicated diverticulitis. Complicated diverticulitis is staged by the Hinchey classification 1-4 (1: mesocolic/pericolic abscess, 2: pelvic abscess, 3: purulent peritonitis, 4: faecal peritonitis). Diverticulitis is suspected in case of lower left quadrant abdominal pain and tenderness associated with fever and raised WBC and/or CRP; but the clinical diagnosis is not sufficiently precise. Abdominal CT confirms the diagnosis and enables the classification of the disease according to Hinchey. The distinction between Hinchey 3 and 4 is done by laparoscopy or, when not possible, by laparotomy. Uncomplicated diverticulitis is treated by conservative means. There is no evidence of any beneficial effect of antibiotics in uncomplicated diverticulitis, but antibiotics may be used in selected cases depending on the overall condition of the patients and the severity of the infection. Abscess formation is best treated by US- or CT-guided drainage in combination with antibiotics. When the abscess is &lt; 3 cm in diameter, drainage may be unnecessary, and only antibiotics should be instituted. The surgical treatment of acute perforated diverticulitis has interchanged between resection and non-resection strategies: The three-stage procedure dominating in the beginning of the 20th century was later replaced by the Hartmann procedure or, alternatively, resection of the sigmoid with primary anastomosis. Lately a non-resection strategy consisting of laparoscopy with peritoneal lavage and drainage has been introduced in the treatment of Hinchey stage 3 disease. Evidence so far for the lavage regime is promising, comparing favourably with resection strategies, but lacking in solid proof by randomized, controlled investigations. In recent years, morbidity has declined in complicated diverticulitis due to improved diagnostics and new treatment modalities. Recurrent diverticulitis is relatively rare and furthermore often uncomplicated than previously assumed. Elective surgery in diverticular disease should probably be limited to symptomatic cases not amenable to conservative measures, since prophylactic resection of the sigmoid, evaluated from present evidence, confers unnecessary risks in terms of morbidity and mortality to the individual as well as unnecessary costs to society. Any recommendation for routine resection following multiple cases of diverticulitis should await results of randomized studies. Laparoscopic resection is preferred in case of need for elective surgery. When malignancy is ruled out preoperatively, a sigmoid resection with preservation of the inferior mesenteric artery, oral division of colon in soft compliant tissue and anastomosis to upper rectum is recommended. Fistulae to bladder or vagina, or stenosis of the colon may be dealt with according to symptoms and comorbidity. Resection of the diseased segment of colon is preferred when possible and safe; alternatively, a diverting stoma can be the best solution." }, { "id": "pubmed23n0759_4878", "title": "Effectiveness of clinical guidelines in the management of acute sigmoid diverticulitis.

In subjects with recurrences (26%), these were either similar to or less than the first episode in 84% of the cases. The present study shows that ultrasound constitutes a feasible technique for diagnosing acute diverticulitis.

The most common presentation is uncomplicated acute diverticulitis that can be managed conservatively with bowel rest and antibiotics. However, some patients will present with diverticular abscesses or purulent or faeculent peritonitis due to perforated diverticular disease. Whilst most mesocolic abscesses can be managed with percutaneous drainage alone, pelvic abscesses are associated with a higher rate of future complications and usually require percutaneous drainage followed by interval sigmoid resection. Patients who require emergency surgery for complicated acute diverticulitis most commonly undergo a Hartmann's procedure, although resection with primary anastomosis and laparoscopic peritoneal lavage have emerged as alternative treatment options for patients with purulent peritonitis in recent years. However, robust evidence from randomized trials is lacking for these alternative procedures, and the studies that have reported good outcomes from them have included carefully selected patient groups. There has been a move away from recommending elective prophylactic colectomy after two episodes of acute diverticulitis in the light of evidence that most patients will not experience a significant recurrence of their symptoms; elective surgery is indicated for those with ongoing symptoms, pelvic abscesses, complications-such as fistulating disease, strictures or recurrent diverticular bleeding-and those who are at high risk of perforation during future episodes, for example, due to immunosuppression, chronic renal failure or collagen-vascular diseases.

It is a high honor, indeed, to join a list of very distinguished predecessors. And for this opportunity to tell you about my passion in medicine and science, I am most grateful. Most of you in this room have passing knowledge of polycystic kidney disease, probably hearing about it in your medical school Pathology course where you were shown an especially grotesque, enormously enlarged kidney either encased in transparent plastic or submerged in a bucket of formaldehyde. In that minute or two when PKD was discussed in lecture, you may have been told that this is a rare, hereditary disorder that causes kidney failure and that nothing can be done to alter that course. Unless you chose to specialize in General Internal Medicine or Nephrology, you may not have encountered PKD again until today, despite the fact there are approximately 600,000 PKD patients in the USA and over 10,000,000 worldwide, and it accounts for approximately 5% of non-diabetic dialysis and renal transplant patients (Table 1). I might have overlooked PKD as well had it not been for a close friend that I grew up with who had inherited the disease from his mother. He was very open about the fact that he had cysts in his kidneys that caused bleeding into the urine from time to time, especially after a solid hit during a game of tackle football. We remained friends long after I left home for college and medical school. At an early stage of my research career in medicine, while wondering how nephron segments processed glomerular filtrate, I inadvertently discovered that renal tubules could secrete as well as reabsorb salt and water. This was quite an unexpected finding at the time (1). But it occurred to [table: see text] me that this might be a means to fill renal cysts with fluid and so I decided to learn more about the pathology and pathogenesis of PKD. This didn't take long, because there wasn't much literature on the subject. The clinical manifestations of PKD were described in the 19th century European medical literature and Sir William Osler had published on the topic in this country, but by and large only a few descriptions of small groups of patients were reported through the middle of the 20th century. In 1957, Dalgaard (2) reported in a classic doctoral thesis that the most common type of hereditary PKD is transmitted as an autosomal dominant trait (ADPKD) with complete penetrance. It is a bilateral renal condition, but cysts also occur in the liver (approximately 60%), pancreas (approximately 10%) and various other organs, and it is associated with cerebral aneurysms in approximately 5% of patients. A recessive form that affects infants and children primarily (ARPKD), is much rarer than ADPKD and commonly leads to death in infancy in association with massively enlarged kidneys (Table 2). I was also attracted to the study of PKD because the etiology was not in question: it had to be mutated DNA. Yet that fact proved to be a hindrance in attaining research support. As some of you will recall, not too long ago genetic diseases were viewed by kidney-oriented NIH review panels to be incurable. I was advised that a young scientist's time would be better spent determining how the kidneys excrete salt and water. Fortunately, the era of molecular genetics and biology was upon us, and we quickly learned that uncommon genetic disorders could lead to the discovery of novel molecules in metabolic and structural pathways. And that is just what happened in the PKD field. The autosomal dominant form of PKD led to the discovery of a unique family of highly complex proteins long before they would have been selected from a gene or proteomic micro-array by some desperate graduate student or fellow. The chromosomal location of the major ADPKD genotype, PKD1, was defined in 1985 (3), a date that marks the beginning of a remarkable period of discovery." }, { "id": "InternalMed_Harrison_22004", "title": "InternalMed_Harrison", "score": 0.011164372336938708, "content": "is because there is an increased frequency of developing simple renal cysts with age.

These criteria have a lower sensitivity for patients with a PKD2 mutation because of a late onset of ADPKD2. CT scan and T2-weighted MRI, with and without contrast enhancement, are more sensitive than ultrasonography and can detect cysts of smaller size. However, a CT scan exposes the patient to radiation and radiocontrast, which may cause serious allergic reactions and nephrotoxicity in patients with renal insufficiency. T2-weighted MRI, with gadolinium as a contrast agent, has minimal renal toxicity and can detect cysts of only 2–3 mm in diameter.

He struck his head on the left side and lost consciousness for several seconds until shaken awake. He was nauseous and disoriented initially but without emesis or incontinence. He was taken to the local emergency department where he was admitted for 1 day and diagnosed with closed head injury, left frontal epidural hematoma, and question of postconcussive syndrome. Eddie has gone back to see the neurosurgeon twice over the last 6 months for scheduled visits and since the accident has had no further treatment.Eddie's mother reports that before the accident, if she read him a story from a book, he could remember the details from the story. Currently, he does not have good memory recall. Before the trauma, he did not attend a preschool program but stayed home with his mother full time. Eddie's first formal schooling has been kindergarten this year. When they moved, the neurosurgeon recommended he start school at the end of September given his head trauma in August. He had a recent computed tomography completed 3 months ago showing the epidural hematoma had completely resolved and the study was otherwise normal. His mother reports he had an evaluation the spring before the accident for a kindergarten screening test and was reported as \"excellent.\" Eddie's birth and medical history are otherwise unremarkable except for some seasonal allergies. He has not had a loss in language skill, although his mother reports he did not speak during his hospitalization. He would just stare and nod his head if someone would ask him a question. No family history of any learning or behavioral difficulties on either side of the family. Eddie has 2 older brothers, 10 and 7 years of age, with no learning issues.What would you do next?" }, { "id": "pubmed23n0224_13833", "title": "Age at clinical onset and at ultrasonographic detection of adult polycystic kidney disease: data for genetic counselling.", "score": 0.00980392156862745, "content": "Few reports are available on the age-related risk of relatives of affected persons to manifest adult polycystic kidney disease (APKD).

The best answer to this question is number 5. Most of the lesions identified as L-SIL are associated with HPV infection: for this reason, it is advisable to stop smoking, as this is a factor in the progression of the said infection. On the other hand, according to the latest studies, 70% of the cytologies reported as LSIL will remit, 15% will persist and another 15% will show a more severe cytology, without being able to differentiate whether it is a biological progression or a lesion hidden in the initial cytology. Because of this, it is best to return for a follow-up at 6 months. Given the woman's personal history (more than 5 sexual partners and repeat infections) and her age, a referral for colposcopy would be ideal. However, answer 5 says control in 6 months, but does not specify which control (it could be a colposcopy or cytology).

Demonstration of surgical technique using slides, pictures, and video. Private hospital. Thirty-two-year-old nulligravid woman presenting to the gynecology clinic with one episode of intermenstrual bleeding, regular menstrual cycles with normal flow, and no history of dysmenorrhoea or dyspareunia. The genital local examination was normal, and speculum examination showed multiple vaginal lesions like polyps in the proximal posterior two-thirds and right lateral vaginal walls. Her transvaginal ultrasound read a normal uterus with a right ovarian simple cyst. The surgeon performed an outpatient operative vaginoscopy using a 5-mm continuous flow office hysteroscope with a 2.9-mm rod lens optical system and a 5F working channel. Distension of the vagina was achieved with a normal saline solution, and an intrauterine pressure of 50 to 60 mm Hg was maintained by an irrigation and aspiration electronic pump. An inspection of the vaginal walls, fornices, and the external cervical os (Fig. 1) revealed 10 vaginal lesions like polyps in the proximal two-thirds of the posterior and right lateral vaginal wall. The vaginal lesions (Fig. 2) varied in size from 0.5 cm to 4 cm. An excisional biopsy was performed and the sample sent for histopathologic evaluation. The vaginal lesions &lt;2 cm in length were excised by cutting the base with scissors or using a bipolar vaporization electrode, which was connected to an electrocautery unit by a bipolar high-frequency cord. Vaginal lesions &gt;2 cm were excised with the TruClear 5C Hysteroscopic Tissue Removal System (HTRS) with a zero-degree scope using the 2.9-mm incisor with a 5-mm cutting window at one end attached to a reusable handpiece with two connectors-one to the motor unit and second to the suction bottle with a collection bag. The overall diameter of TruClear 5C is 5.7 mm, and the optic size is 0.8 mm. The same irrigation pump is compatible with HTRS, and the pressure was increased to 150 mm Hg to maintain vaginal distension. Three factors influenced our decision to use the HTRS intraoperatively: the number and size of the vaginal lesions and the surgical time in the outpatient setting. A mechanical system that works on the principle of excising and aspirating tissue, the HTRS incisor has a rotatory action with the excising window placed against the most distal part of the vaginal lesions. The cutting action is controlled via a foot pedal attached to a motor control with 800 rotations per minute. The handpiece remains stationary while the polyp is excised and aspirated through the window into the collection bag. Minimal bleeding occurred and stopped spontaneously. The institutional ethics committee exempted this case report from review, and we obtained informed written consent from the patient. All vaginal lesions excised in an outpatient setting via vaginoscopy technique without anesthesia. The operative time with the Bettocchi hysteroscope was 14 minutes, and HTRS was 6 minutes. The patient did not complain of pain but did describe minimal discomfort, rated on the visual analog scale as 2 (where ≥5 is severe pain). She was discharged 1 hour later. The histopathology was reported as vaginal endometriosis (ectopic presentation of endometriosis is rare, accounting for 0.02% of cases). After surgery, she was started on cyclical oral contraceptive pills (OCP) in the combination of 30 mg of ethinyl estradiol + 2 mg of dienogest because she desired to delay pregnancy by 1 year. She remained asymptomatic for 6 months. These contraceptive hormones are available in the form of oral pills, vaginal rings, and transdermal patches, and a physician can provide OCP continuously or cyclically. Continuous OCP is more efficacious for control of dysmenorrhoea, but cyclical OCP is preferred because it is affordable, tolerable, effective, produces no unpredictable bleeding, and slows the progression of the disease. (A cohort study found the contraceptive vaginal ring to be more effective for symptom-control in rectovaginal endometriosis with higher patient satisfaction than the transdermal patch; vaginal rings or transdermal patches are not available in some countries.) CONCLUSION(S): Vaginoscopy allows a more in-depth visualization of the vagina with complete inspection and removal of all polyps. Vaginoscopy is feasible in the outpatient setting and allows a comfortable, ergonomic position for the surgeon. Vaginoscopy or no-touch technique avoids the use of a speculum or tenaculum and results in minimal pain during the outpatient procedure." }, { "id": "pubmed23n1137_3792", "title": "Superficial spreading cervical squamous cell carcinoma in situ involving the endometrium: a case report and review of the literature.", "score": 0.014810778680404198, "content": "The spread of cervical squamous cell carcinoma to the inner surface of the uterus with replacement of the endometrium is rare.

Of the 326 patients, 268 patients were followed by repeat Pap smears, colposcopy, cone biopsy, or endometrial curettage. The incidence of AGUS on Pap smears is approximately 0.08%. The mean age of the patients was 43 years (range 22-79 years). The most common complaint was abnormal vaginal bleeding. The gross findings of the cervix were normal to mild erosion. The following past histories of patients could affect the AGUS results on Pap smear: 30 had cone biopsy, 21 had Pap smears on pregnancy and within 8 weeks after delivery or evacuation, 3 were on hormonal replacement therapy, 2 had intrauterine devices for contraception, and 5 were undergoing follow-up after treatment of cervical cancer.

AGUS on Pap smears showed various benign and malignant lesions of the cervix or uterus. The clinicians must communicate with the pathologists regarding the patient's clinical information as well as the origin of the atypical glandular cells in Pap smears. We recommend that patients with AGUS on Pap smear should undergo immediate intensive diagnostic studies, including colposcopic-directed biopsy with endocervical curettage or cone biopsy, to detect cervical lesions and endometrial curettage to detect endometrial lesions." }, { "id": "pubmed23n0254_18725", "title": "Predictive factors from cold knife conization for residual cervical intraepithelial neoplasia in subsequent hysterectomy.", "score": 0.013988023952095809, "content": "The optimal management of cervical intraepithelial neoplasia after cold knife conization remains controversial. Reliable predictors of residual dysplasia in the cervix after cold knife conization have not been consistently identified. This study was initiated to examine the accuracy of the traditional factors used to predict residual dysplasia in hysterectomy specimens after cold knife conization. A retrospective 10-year chart review identified a cohort of 1272 patients who underwent cold knife conization, of whom 311 had a subsequent hysterectomy within 1 year of conization. Residual disease was defined as cervical intraepithelial neoplasia or cancer in the hysterectomy specimen. All cone specimens were completely submitted for pathologic examination, and the following factors were analyzed for their predictive value: degree of dysplasia, margin involvement, endocervical gland involvement, and status of the endocervical curettage. The predictive value of age, race, gravidity, parity, socioeconomic status, cigarette smoking, and marital status were also examined. The chi 2 test, t test, and logistic regression were used for statistical analysis. Dysplasia or cancer were identified in 1066 (84%) of the 1272 patients who underwent cold knife conization. Of the 311 patients having a subsequent hysterectomy, 106 (34%) had residual disease in their hysterectomy specimen. By multivariate analysis only increasing age and degree of dysplasia were predictive of residual disease. The odds ratio of residual disease in the hysterectomy specimen for a 25-year-old woman was 2.7 (95% confidence interval 1.6 to 4.4) compared with a 40-year-old woman whose odds ratio was 4.9 (95% confidence interval 2.2 to 10.8). The presence of dysplasia in the cold knife conization specimen conferred an odds ratio of 12.1 (95% confidence interval 2.7 to 54.5) of identifying residual disease. Dysplasia involving the ectocervical margin, endocervical margin, and endocervical glands was not predictive of disease in the hysterectomy specimens. Endocervical curettage was not performed in 44% of the patients, preventing reliable statistical evaluation. Further analysis indicated that residual disease was found in 32% of the hysterectomy specimens with negative margins, in 31% with no endocervical gland involvement, and in 23% with a negative endocervical curettage sample. The presence or absence of dysplasia in the cold knife conization ectocervical margin, endocervical margin, and endocervical glands was not predictive of residual dysplasia in post-cold knife conization hysterectomy specimens.

It is the fourth most common reason why women attend gynaecology outpatient clinics and accounts for one-fifth of all gynaecology outpatient referrals. Initial treatment in primary care is medical - either by means of oral or injected medication or the levonorgestrel-intrauterine system (Mirena®). If medical treatment fails then surgical treatment can be offered, either endometrial ablation (EA), which destroys the lining of the cavity of the uterus (endometrium), or hysterectomy, i.e. surgical removal of the uterus. While effective, conventional hysterectomy is invasive and carries a risk of complications due to injury to other pelvic structures. The procedure can be simplified and complications minimised by undertaking a 'supracervical' hysterectomy where the cervix is left in situ and only the body of the uterus removed. Recent advances in endoscopic technologies have facilitated increased use of laparoscopic supracervical hysterectomy (LASH) which can be performed as a day-case procedure and is relatively easy for the surgeon to learn.

During routine ultrasound-enhanced bimanual examination, nine postmenopausal women with unremarkable palpatory findings and no history of bleeding were found to have endometrial fluid collections. The patients were 9-24 years postmenopausal. All underwent prompt endometrial sampling. Each woman had some degree of cervical stenosis as judged by the operator. At curettage, all had scant tissue, which was reported by the pathologist as \"inactive endometrium.\" Ultrasound scans on each patient were rereviewed, and it was found that the endometrium surrounding the fluid was uniformly 3 mm thick or less. Subsequently, 21 additional patients with small endometrial fluid collections have been seen. Eighteen of these had thin endometrium peripherally and were followed conservatively for 6-26 months. Six cases resolved and 12 remained unchanged. Three patients had a thickened heterogeneous endometrium peripheral to the fluid collection. In one, D&amp;C was unsuccessful in two attempts because of cervical stenosis, and hysterectomy was performed. A 15-mm endometrial polyp was found. Two other patients with thickened endometrium surrounding the fluid had D&amp;C, and hysteroscopy revealed simple hyperplasia without atypia. CONCLUSIONS. Normal atrophic postmenopausal endometrium in association with cervical stenosis can produce endometrial fluid collections, seen easily on vaginal probe ultrasound. If the endometrial tissue surrounding the fluid is thin (3 mm or less), the endometrium is invariably inactive and sampling is not necessary. If the peripheral endometrium is thicker than 3 mm, sampling is mandatory because the tissue cannot be expected to be invariably inactive and sampling is not necessary. If the peripheral endometrium is thicker than 3 mm, sampling is mandatory because the tissue cannot be expected to be inactive. Thus, the presence or amount of fluid is not as important as the thickness and character of the surrounding tissue." }, { "id": "pubmed23n0870_19261", "title": "Endometrial study in patients with postmenopausal metrorrhagia.", "score": 0.014932386571294313, "content": "The aim of the study was to devise a strategy to diagnose malign endometrial pathologies (adenocarcinoma or atypical hyperplasia) that minimizes the number of invasive tests done (hysteroscopy, aspiration biopsy or curettage) with no loss of its detection efficiency.

If the endometrium measured 8 mm or more (35 patients) hysteroscopy and directed biopsy was performed. In the 35 patients, hysteroscopy and curretage revealed polyps in 18 cases (51.4%), proliferation in 1 case (2.9%) and atrophy in 16 cases (45.7%). In 54.3% (19 cases) of the patients the histopathological finding was a polyp or benign proliferation of the endometrium in agreement with the thickened endometrium seen with TVU. In the remaining 45.7% (16 cases) of the patients a thickened endometrium by transvaginal ultrasound was false positive as the hysteroscopic and subsequent histopathological diagnosis only showed atrofia of the uterine endometrium. In almost half of the patients the TVU gave a misleading picture concerning the condition of the endometrium. Changes in the myometrium and related connective tissue could be misinterpreted by the ultrasound technique as changes in the endometrium. These results may confirm the theory that stimulation and changes by antiestrogenic treatment of the uterine tissue is not only restricted to the endometrium. In patients with thickened endometrium measured by TVU, a dilatation and curettage is not sufficient, as TVU has not the ability to differentiate between endometrial polyps and myometrial changes.

Because postmenopausal bleeding can be the presenting symptom of endometrial cancer, any woman with this symptom should be evaluated to diagnose or exclude carcinoma. Over the last two decades, the role of ultrasound in the evaluation of postmenopausal bleeding has changed markedly, from little or no role in 1990 to a major role today. In the intervening years, numerous studies have shown that ultrasound is at least as sensitive as endometrial biopsy for endometrial cancer and that ultrasound can reliably exclude cancer without the need for biopsy in some women with postmenopausal bleeding. In particular, numerous studies have shown that women with an endometrial thickness of 4 mm or less have an extremely low likelihood of endometrial cancer and thus do not need to undergo endometrial biopsy. Ultrasound can also help in the selection of an appropriate biopsy technique. In a woman with postmenopausal bleeding and a thick endometrium, a sonohysterogram can determine whether the endometrium is diffusely thick or has focal areas of thickening. With diffuse thickening, a blind endometrial biopsy is appropriate. When there are one or more focal areas of thickening, hysteroscopic biopsy is likely to be the better choice. We present two clinical algorithms, either of which is an acceptable approach to the use of ultrasound and/or endometrial biopsy in women with postmenopausal bleeding: the \"ultrasound-first\" approach and the \"biopsy-first\" approach." }, { "id": "wiki20220301en560_9974", "title": "Pharmacokinetics of progesterone", "score": 0.009259259259259259, "content": "were assessed in three of the studies via endometrial biopsy and the results were mixed.

Reading the case, we are discarding options: child with otalgia, but without fever or acute inflammatory signs: it is neither 1 (recurrent acute otitis media) nor 5 (mastoiditis). On otoscopy, a pinkish and amber eardrum is observed: there are no scales, so it is not 4 (cholesteatomatous chronic otitis media); nor perforations or adhesions, so it is not 3 (simple chronic otitis media). Otoscopy is characteristic of serous otitis media (answer 2 correct). It is known by ENT, pediatricians and family physicians that in the month following an acute otitis media, the middle ear is occupied by a mucous content whose evolution should be monitored. I do not think that this is a contestable issue either.

Patents were searched using the key term \"acute otitis media\" from www.google.com/patents, http://espacenet.com, and www.freepatentsonline.com. Acute otitis media affects over 80% of children before their third birthday and 30 to 45% of these children have suffered two or more episodes. Streptococcus pneumoniae, nontypable Haemophilus influenzae, and Moraxella catarrhalis are the most frequently isolated middle-ear pathogens. The diagnosis is based on acute onset of symptoms such as otalgia and fever, middle ear inflammation such as erythema of the tympanic membrane, and middle ear effusion. The choice of treatment method depends on the age of the child, laterality, and the severity of the disease.

Metastases to the pancreas are extremely rare. Here we present a man with pancreatic metastases from PTC, report our experience with sorafenib therapy, and discuss the role of endoscopic ultrasound (EUS)-guided biopsy in its diagnosis. A 56-year-old man underwent total thyroidectomy, right-modified neck dissection, and radioactive iodine (RAI) remnant ablation for PTC at age 47 years (in 2002). Between 2002 and 2007, he had three more neck surgeries, two RAI therapies, and external beam radiotherapy for persistent and subsequently metastatic PTC. In 2008, a computed tomography/positron emission tomography (CT/PET) scan showed an 18F-fluorodeoxyglucose (FDG)-avid pancreatic focus. Magnetic resonance imaging (MRI) revealed a pancreatic nodule at the same location. An EUS-guided biopsy confirmed the diagnosis of pancreatic metastasis from PTC, and molecular studies showed positive BRAF(V600E) mutation. He was treated with sorafenib for 6 months. Although a lung CT scan done 2 months after initiation of sorafenib suggested stability of the disease, MRI studies done at 3 and 6 months showed clear progression with an increase in the size of the lung and pancreatic metastases. Subsequently, he developed liver, bone, and omental metastases. He died in July 2011, 9 years and 8 months after the initial diagnosis of PTC and 20 months after discovery of the pancreatic metastasis. A middle-aged man with PTC developed lung metastases despite multiple surgeries and RAI therapies. Seven years after the initial diagnosis, a pancreatic metastasis was accidentally discovered. Both the metastasis and the primary thyroid tumor are positive for BRAF(V600E) mutation. The lung and pancreatic metastases progressed while the patient was receiving sorafenib for 6 months, and the patient died 20 months after diagnosis of pancreatic metastasis. PTC rarely metastasizes to the pancreas. In this patient, an FDG PET scan and EUS-guided biopsy played important roles in the diagnosis.

It is more common on sun-exposed areas, especially on head and neck in elderly patients (2). Regional lymph node involvement is reported to be less frequent than in other cutaneous melanomas (3). Desmoplastic melanoma can clinically mimic a wide spectrum of benign and malignant lesions, including Bowen's disease, desmoplastic nevus, basal cell carcinoma, squamous cell carcinoma, lentigo maligna, dermatofibrosarcoma protuberans, peripheral nerve sheath tumors, cysts, or hypertrophic/keloid scars (4). Regarding its appearance, at the time of diagnosis DM frequently presents as advanced lesions with deep infiltration. A 60-year-old man presented with an one-year history of an asymptomatic, erythematous, well-defined plaque in the right lumbar region (Figure 1). Dermatological examination revealed a 5×5 cm, pink/red infiltrated plaque accompanied by a 6 mm dark-brown melanocytic lesion. Dermoscopically, atypical vascular structures in the form of linear, irregular, and dotted vessels, milky-red areas, and atypical pigment network, and streaks were observed near the melanocytic lesion (Figure 2). A 4 mm punch biopsy was performed on the erythematous plaque next to the melanocytic lesion, and a dermal-based, paucicellular proliferation of atypical spindle cells without melanin in a sclerotic stroma was found histologically (Figure 3, a). Immunohistochemically, dermal spindle cells were stained with S-100 and HMB45 antibodies (Figure 3, b). The patient was histologically diagnosed with melanoma, of the desmoplastic subtype. The lesion was totally excised with 2 cm clear margins. A diagnosis of nonulcerated nodular melanoma with a Breslow thickness of 4 mm and a mitotic index 1/mm2 was established. Sentinel lymph node biopsy revealed no metastases. No systemic metastases were detected in PET-CT scanning and cranial magnetic resonance imaging. The patient remained under follow-up and has been free of any local recurrence or primary or systemic metastasis for 3 years. Dermoscopic characteristics of DM are not well known, probably due to it not being considered a melanocytic lesion. Debarbieux et al. first reported the dermoscopic features of desmoplastic melanoma in six cases (5). They found that only half of the cases presented one classical feature of a melanocytic lesion, whereas the other cases were diagnosed based on the presence of figures of regression such as white scar-like and \"peppering\", multiple (&gt;4) color, and melanoma-related vascular patterns (five out of six) such as linear-irregular vessels and milky-red areas (5). In the largest DM case series, Jaime et al. reported that all DM featured at least 1 melanoma-specific structure, with atypical vascular structures being the most common (6). Similarly, in our patient dermoscopy showed an atypical pigment network and streaks, atypical vascular structures, and milky-red areas, which is predictive for melanoma. We reported this case to serve as a reminder to consider desmoplastic melanoma in the differential diagnosis of pink tumoral lesions despite its rarity and atypical localization." }, { "id": "pubmed23n0282_9930", "title": "[Prevalence, rate of correct clinical diagnosis and mortality of cancer in 4,894 elderly autopsy cases].", "score": 0.009523809523809525, "content": "The prevalence, rate of correct clinical diagnosis and mortality of cancer were analyzed in 4,894 consecutive autopsies at the Tokyo Metropolitan Geriatric Hospital from 1972 to 1990. average age and standard deviation of patients was 78.1 +/- 9.1 years.

CASE 2: A 73-year-old woman was referred to the dermatology clinic for evaluation of a painful, ulcerated, 3-cm lesion in the umbilicus (Figure 1). She was otherwise asymptomatic. A skin biopsy showed neoplastic glandular cells infiltrating among collagen bundles (Figure 2). Stainings for mucin and for CK7 were positive, while staining for CK20 was negative. An abdominopelvic CT scan demonstrated a 3.5-cm space-occupying lesion in the liver. Results of gastroscopy, colonoscopy, chest computed tomographic (CT) scan, and mammography were normal. Serum levels of the tumor-associated protein CA125 were elevated to 164 units, while those of CA 19-9 and carcinoembryonic antigen were within normal range. A gynecologic examination and a transvaginal ultrasound were normal. The patient had no personal or family history of any malignancy or any risk factors for developing a carcinoma. The patient was scheduled for a palliative resection of the umbilical nodule, combined with a laparoscopic inspection in search of the undetected primary tumor. She refused surgery and was lost to follow-up. She died 4 months after the initial diagnosis of umbilical metastasis. CASE 3: A 51-year-old man was aware of a silent mass in his umbilicus for 2 years without seeking medical advice. Following 2 weeks of increasing pain in this area, he was referred to the emergency room for a suspected incarcerated umbilical hernia. Surgery revealed a mass attached to the fascia and peritoneal fat. The mass was removed and diagnosed as a poorly differentiated adenocarcinoma, staining positively for carcinoembryonic antigen, and negatively for CK20, CK7, prostate-specific antigen, and prostatic acid phosphatase. Both gastroscopy and colonoscopy failed to detect the primary tumor. An abdominopelvic CT scan was normal, but a CT scan of the chest disclosed a nodule measuring 2.5 x 1.5 cm in the lower lobe of the right lung. On bronchoscopy, it was found to be an invasive adenocarcinoma, consistent with a primary tumor of the lung. The patient was a heavy smoker (45 pack-years). The patient received 4 cycles of combined chemotherapy with carboplatine and gemcitabine, with no improvement. A month later, the patient complained of abdominal pain. Following demonstration of intra-abdominal spread of disease by CT scan, a second line chemotherapy was instituted with paclitaxel. A month later the patient's condition deteriorated and he complained of cough, sweating, and pain along the right leg. A bone scan revealed bone metastases in the right femur and left tibia. Two weeks later he was admitted to the hospital with intestinal obstruction and underwent laparotomy. He had massive intra-abdominal spread of cancer and ascites. Only a palliative colostomy was performed. The patient died 3 weeks later, 9 months after the diagnosis of adenocarcinoma of the lung.

The interval between neoplasms, smoking habits, histological subtypes and survival were also analysed. Patient follow-up was &gt;or=5 years. We found 231 patients with NMIBC, 39 of which had a second primary neoplasm: 10 lung cancer, one pancreas, one gastric, one pharynx, one liver, one parathyroid, one oesophageal, five basal cell carcinoma, three larynx, two colon, three rectal and 10 prostate. In patients with lung cancer, NMIBC was the first primary tumour. Overall, the median (range) interval between occurrence of NMIBC and lung cancer was 54.2 (8-168) months. For the relationship between the observed and expected cases of lung cancer, after normalizing our frequencies to the sex ratio and age of our group of patients, the risk of lung cancer was 10.27-fold higher in patients with NMIBC as compared with the general population of Catalonia (95% confidence interval 4.92-18.88). We consider that an annual examination for the detection and prevention of lung cancer must be included in clinical guides for patients with NMIBC.

Physical examination showed he was hypertensive and had dysarthria; it was not possible to observe his gait due to pain in the right foot presumed to be due to a gout crisis. A stroke was thought to be the cause of these neurological deficits so a head CT scan was performed but did not show any alterations.

A 43-year-old Asian female presented to the emergency department with generalized itching, hives, and postural dizziness after taking a slow-release diclofenac sodium 100 mg tablet. On admission, the patient was tachycardic with a supine blood pressure of 200/100 mmHg. She had urticaria and bilateral rhonchi. A clinical diagnosis of anaphylaxis was made. She was treated with intravenous hydrocortisone and chlorpheniramine, but intramuscular adrenaline was withheld owing to her high blood pressure. She was kept in the supine position, and her vital parameters were closely monitored. Although the respiratory and cutaneous symptoms improved with treatment, her blood pressure remained elevated. Forty minutes later, the postural dizziness recurred as she sat up on the bed and her blood pressure plummeted from 198/100 mmHg to 80/60 mmHg. She was put back in the supine position immediately, and the blood pressure was restored with three doses of intramuscular adrenaline and a fluid bolus. Her postural symptoms completely resolved after adrenaline, but her blood pressure remained elevated. Two weeks after the initial presentation, a diagnosis of essential hypertension was made, which probably had been undetected. In anaphylaxis, where the cardiovascular system is involved, a blood pressure reduction from baseline is expected in patients with preexisting hypertension. Despite cardiovascular involvement, our patients' blood pressure on presentation to the emergency department was much higher than her pretreatment ambulatory blood pressure, thus making this presentation unusual. Diagnosis and treatment of anaphylaxis can be delayed in patients presenting with high blood pressure. Postural symptoms should alert the clinician to cardiovascular involvement despite elevated supine blood pressure.

Adrenaline was also administered to the eyes by giving 2 drops (1 mg) of Isopto-Epinal (Alcon, 10 mg X ml-1). Finally, 0.5 ml (0.5 mg) of adrenaline was given subcutaneously in the upper arm of the same individuals. The systemic absorption was determined by measuring plasma adrenaline levels and effects on blood pressure, heart rate and finger tremor before and 5, 15, 30, 60, 90, and 120 min after adrenaline administration. Adrenaline given as eye-drops did not have any significant effect on these parameters. Subcutaneously administered adrenaline caused within 5 min a significant increase of plasma adrenaline level (from 1.0 +/- 0.2 to peak of 6.5 +/- 1.2 nM) which gradually decreased during 2 h. This mode of adrenaline administration increased the systolic blood pressure by a maximum of 11 +/- 3.5 mmHg, heart rate by 9 +/- 2.2 beats X min-1, tremor ratio by 4 +/- 0.6 and reduced the diastolic blood pressure by 18 +/- 4.7 mmHg.

However, tracheal adrenaline (epinephrine) injection has been recently shown to be associated with detrimental decrease in blood pressure. This was attributed to exaggerated early beta2 mediated effects unopposed by alpha-adrenergic vasoconstriction. We hypothesized that endobronchial adrenaline administration is associated with better drug absorption, which may abolish the deleterious drop of blood pressure associated with tracheal drug administration. To determine haemodynamic variables after endobronchial adrenaline administration in a non-arrest canine model. Prospective, randomized, laboratory study. Adrenaline (0.02, 0.05, 0.1 mg/kg) diluted with normal saline was injected into the bronchial tree of five anaesthetized dogs. Injection of 10-ml saline served as control. Heart rate, blood pressure and arterial blood gases were monitored for 60 min after drug instillation. The protocol was repeated after 1 week. Adrenaline at a dose of 0.02 mg/kg produced only a minor initial decrease in diastolic (from 90 +/- 5 to 78 +/- 3 mmHg, P=0.05), and mean blood pressure (from 107 +/- 4 to 100 +/- 3 mmHg, P=0.05), in all dogs. This effect lasted less then 30 s following the drug administration. In contrast, higher adrenaline doses (0.05 and 0.1 mg/kg) produced an immediate increase in diastolic (from 90 +/- 5 to 120 +/- 7 mmHg; and from 90 +/- 5 to 170 +/- 6 mmHg, respectively), and mean blood pressure (from 107 +/- 4 to 155 +/- 10 mmHg; and from 107 +/- 4 to 219 +/- 6 mmHg, respectively). All adrenaline doses resulted in an immediate increase in systolic blood pressure and pulse. Endobronchial administration of saline (control) affected none of the haemodynamic variables. In a non-arrest model, endobronchial adrenaline administration, as opposed to the effect of tracheal adrenaline, produced only a minor decrease in diastolic and mean blood pressure. We suggest that endobronchial adrenaline administration should be investigated further in a CPR low-flow model when maintaining adequate diastolic pressure may be crucial for survival." }, { "id": "pubmed23n0124_10297", "title": "Adrenaline and stress-induced increases in blood pressure in rats.", "score": 0.009523809523809525, "content": "Stress was induced by immobilizing the hind limbs of rats for 12 days and housing the rats in individual cages.

After 10 and 12 days of immobilization and isolation, the stressed rats had significantly higher blood pressures (ca. 10 mmHg) and higher cardiac adrenaline levels (ca. 90%). After adrenal medullectomy cardiac adrenaline levels were markedly reduced in both stressed and control rats. Furthermore, the stressing procedure did not cause a rise in blood pressure in adrenal-medullectomized rats. Desipramine HCl (2 mg/kg per day), administered orally to block the neuronal uptake of adrenaline, prevented the elevation in blood pressures and cardiac adrenaline levels. Propranolol HCl (2.8 mg/kg per day), orally, also prevented the rise in blood pressure.

She had a history of chronic persistent atrial fibrillation and was being maintained on oral amiodarone as an outpatient. She was admitted with shortness of breath and was found to have atrial fibrillation with rapid ventricular response. She was started on an IV amiodarone bolus. Immediately after a few milliliters of infusion, she complained of shortness of breath, with facial flushing and generalized blanching erythema, followed by severe hypotension and cardiopulmonary arrest. IV amiodarone infusion was suspected to be the culprit and was discontinued immediately. IV epinephrine 0.3 mg was administered, followed by the advanced cardiovascular life support (ACLS) protocol for cardiopulmonary arrest.

He became profoundly diaphoretic and developed systemic swelling, shortness of breath, bradycardia, and hypotension. Emergency medical services transported the patient to the ED, where he was treated appropriately and the symptoms resolved. However, 4 hours later, at time of discharge from the ED, the symptoms recurred. He was admitted to the intensive care unit and monitored for 3 days. Supportive care, steroids, and histamine blockade provided resolution of the symptoms. Cardiac workup was initiated because of the recurrence and severity of bradycardia and hypotension; results of the workup were unremarkable. The patient was discharged in stable condition.

Rapid IV access is challenging, but little evidence exists for other routes of administration. We compared IV, endotracheal (ET), and intranasal routes for adrenaline administration during resuscitation of asphyxiated newborn lambs. <bStudy design:</b Near-term lambs (<in</i = 22) were delivered by caesarean section. Severe asphyxia was induced by clamping the umbilical cord while delaying ET ventilation until blood flow in the carotid artery ceased. Following a 30 s sustained inflation and ventilation for 30 s, we commenced uncoordinated CC at 90/min. We randomized four groups receiving repeated treatment doses (Tds) every 3rd min of (i) IV-Adrenaline (50 μg), (ii) ET-Adrenaline (500 μg), (iii) Nasal-Adrenaline via an atomizer (500 μg), and (iv) IV-saline. If return of spontaneous circulation (ROSC) was not achieved after three Tds by the assigned route, up to two rescue doses (Rds) of IV adrenaline were administered.

The clinical factors that set the stage for drug-induced hypoglycemia are still restricted food intake, age, hepatic disease, and renal disease, both individually and even more so in combination. Drug-induced hypoglycemia continues to be so common that virtually every unconscious patient should be considered hypoglycemic until immediate estimation of the blood sugar level rules it in or out. If ruled in, the clinician should promptly start 10% intravenous glucose and plan to maintain it uninterruptedly for 1 or more days, with added glucagon, hydrocortisone, and diazoxide administration if necessary, until sustained hyperglycemia guarantees that all drug effects have worn off." }, { "id": "pubmed23n0253_21666", "title": "Haemodynamic effects of tracheally administered adrenaline in anaesthetised patients.", "score": 0.008849557522123894, "content": "Ten patients undergoing arterial surgery in the leg received a combined general anaesthetic, which included muscle relaxation and intubation of the trachea, and a regional anaesthetic using a lumbar extradural catheter.

The purpose of the present study was to clarify the changes in hemodynamics caused by drug interaction between adrenaline and an antipsychotic and to evaluate the safety of the combined use of adrenaline and an antipsychotic in an animal study. Male Sprague-Dawley rats were anesthetized with sodium pentobarbital. A catheter was inserted into the femoral artery to measure blood pressure and pulse rate. Rats were pretreated by intraperitoneal injection of chlorpromazine or chlorpromazine and propranolol, and after 20 minutes, saline or 1 of 3 different doses of adrenaline was administered by intraperitoneal injection. Changes in the ratio of mean arterial blood pressure and pulse rate were measured after the injection of adrenaline. Significant hypotension and tachycardia were observed after the injection of adrenaline in the chlorpromazine-pretreated rats. These effects were in a dose-dependent manner, and 100 μg/kg adrenaline induced significant hemodynamic changes. Furthermore, in the chlorpromazine and propranolol-pretreated rats, modest hypertension was induced by adrenaline, but hypotension and tachycardia were not significantly shown. Hypotension was caused by a drug interaction between adrenaline and chlorpromazine through the activation of the β-adrenergic receptor and showed a dose-dependent effect.

We report an interesting case investigating a (near) fatal poisoning. The son of an 84-year-old male discovered a newspaper report stating clinical success with plant extracts in Alzheimer's disease. The mode of action was said to be comparable to that of the synthetic compound 'carbamylcholin'; that is, carbachol. He bought 25 g of carbachol as pure substance in a pharmacy, and the father was administered 400 to 500 mg. Carbachol concentrations in serum and urine on day 1 and 2 of hospital admission were analysed by HPLC-mass spectrometry. Minutes after oral administration, the patient developed nausea, sweating and hypotension, and finally collapsed. Bradycardia, cholinergic symptoms and asystole occurred. Initial cardiopulmonary resuscitation and immediate treatment with adrenaline (epinephrine), atropine and furosemide was successful. On hospital admission, blood pressure of the intubated, bradyarrhythmic patient was 100/65 mmHg. Further signs were hyperhidrosis, hypersalivation, bronchorrhoea, and severe miosis; the electrocardiographic finding was atrio-ventricular dissociation. High doses of atropine (up to 50 mg per 24 hours), adrenaline and dopamine were necessary. The patient was extubated 1 week later. However, increased dyspnoea and bronchospasm necessitated reintubation. Respiratory insufficiency was further worsened by Proteus mirabilis infection and severe bronchoconstriction. One week later, the patient was again extubated and 3 days later was transferred to a peripheral ward. On the next day he died, probably as a result of heart failure. Serum samples from the first and second days contained 3.6 and 1.9 mg/l carbachol, respectively. The corresponding urine concentrations amounted to 374 and 554 mg/l. This case started with a media report in a popular newspaper, initiated by published, peer-reviewed research on herbals, and involved human failure in a case history, medical examination and clinical treatment. For the first time, an analytical method for the determination of carbachol in plasma and urine has been developed. The analysed carbachol concentration exceeded the supposed serum level resulting from a therapeutic dose by a factor of 130 to 260. Especially in old patients, intensivists should consider intoxications (with cholinergics) as a cause of acute cardiovascular failure." } ] } } }

Low blood pressure and a fast heart rate after the event may indicate blood loss or dehydration, while low blood oxygen levels may be seen following the event in those with pulmonary embolism. More specific tests such as implantable loop recorders, tilt table testing or carotid sinus massage may be useful in uncertain cases.

Our study confirms that patients with well-defined symptoms, appropriate physical findings, and concurrent CT and duplex scans, can safely undergo CEA without preoperative angiography.

In 38 to 47% of the patients no etiology is found: these are syncopal attacks of unknown origin. The first diagnostic step comprises noninvasive investigations. A 24-hour recording of the ECG or a 'long strip' improve the diagnostic rate by 10%. They are particularly useful for sick sinus syndromes. The head-up tilt-test has been developed recently. It is very useful for detection of vagovasal syncope and permits to understand the pathophysiology and the therapeutic consequences of these disorders. This test plays a particular role for the diagnosis of syncopes of unknown causes and shows in 24 to 75% of the cases pathologic results. Patients at high risk for ventricular arrhythmia can be recognized by ECG with high amplification. Doppler investigation of the neck vessels, however, seems to be of low diagnostic value in syncopes. Invasive measures are the last line resort. Electrophysiologic studies provide criteria that are well defined. They are useful for detection of ventricular dysrhythmias and conduction disorders. This latter approach is reserved to patients with negative noninvasive tests and in particular with cardiopathy.

Due to its high validity, this technique has become the standard method for evaluation of extracranial occlusive cerebrovascular disease. Further ultrasonic developments like duplex and color duplex sonography have increased the diagnostic possibilities but did not replace continuous-wave sonography in many European ultrasound laboratories. Transcranial ultrasound studies are performed by means of pulsed-wave Doppler or color duplex sonography.

Anisakis simplex is a parasite frequently found in fish. To avoid reactions with this parasite, a diet free of fresh and raw fish (anchovies in vinegar, smoked, salted fish, sushi, etc.) should be followed. Deep-frozen fish or fresh fish previously frozen at -20ºC for at least 5 days before cooking can be consumed, as long as it is cooked at high temperatures >60ºC (roasted, fried, etc.), avoiding raw, grilled or microwaved preparations. It is recommended to consume preferably the tails because the larvae of the parasite are usually close to the viscera of the head.

In the diagnosis of anisakiasis and/or allergy to Anisakis, the antecedent of the prior ingestion of fish as well as the clinical accompaniment can form basic data of considerable orientational value, and endoscopy can reveal the presence of the larvae and make possible their extraction. Besides, in cases of allergy the detection test for specific IgE facing Anisakis simplex, and cutaneous tests with fish should be carried out.

Here, we investigated the prevalence, intensity, and abundance of Anisakis larvae in imported fish and ready-to-eat local fish products in Turkey. A total of 205 ready-to-eat fish products, 100 imported frozen Atlantic salmon (Salmo salar) fillets, and 100 imported frozen whole Atlantic mackerel (Scomber scombrus) were sampled from supermarkets, sushi restaurants, and fish markets. All samples were individually examined using a pepsin digestion technique. In total, 602 Anisakis type I larvae were recovered from 98/100 mackerel. No larvae were found in ready-to-eat products or frozen Atlantic salmon fillets. Overall, 8.8% of the larvae were found in the muscle tissue. The overall mean intensity and abundance of infection in mackerel were 6.14 and 6.02, respectively. The larvae were molecularly identified and their phylogenetic relationships with the relevant Anisakis sequences in GenBank were investigated. For this purpose, a subsample of randomly selected 100 Anisakis larvae were analyzed with PCR-RFLP of the ITS region. The larvae were identified as A. simplex (s.s.) (n = 87) and hybrids (n = 13). ITS and cox2 gene regions of all hybrids and randomly selected 50 A. simplex (s.s.) larvae were sequenced for species confirmation and phylogenetic analyses. No intraspecific nucleotide variation was found among the ITS sequences of either species. Seven and three haplotypes, respectively, were identified for A. simplex (s.s.) and hybrid species according to DNA polymorphism of the cox2 gene. Hybrids in our study clustered within the common A. simplex (s.s.) clade in the cox2 phylogenetic tree indicating the dominance of A. simplex (s.s) in the catching area of Atlantic mackerel.

More recently, allergic reactions to Anisakis ingestion or exposure, such as urticaria, anaphylaxis and even occupational asthma, have been reported. These allergic reactions may also occur when the fish has been properly cooked, and hence these allergens are thought to be heat-stable. Such cases may be diagnosed by skin tests and the determination of specific Anisakis-IgE. However, the specificity of IgE is low, since they may also be present in exposed asymptomatic individuals. Since the eliciting allergens are temperature-stable, prophylactic dietetic measures are indicated. We report a case from Switzerland acquired during a holiday in Portugal.

Total IgE, Anisakis spp.-specific IgE, anti-Ani s 1 and anti-Ani s 4 IgE were repeatedly measured over a median follow-up duration of 49 months in 17 sensitized patients. Anisakis spp.-specific IgE was detected in 16/17 patients throughout the follow-up period. The comparison between baseline and last visit measurements showed significant decreases in both total IgE and specific IgE. The specific IgE values had an exponential or polynomial decay trend in 13/17 patients. In 4/17 patients, an increase in specific IgE level with the introduction of fish to the diet was observed. Three patients reported symptoms after eating aquaculture or previously frozen fish, and in two of those patients, symptom presentation was coincident with an increase in specific IgE level. IgE sensitization to Anisakis spp. allergens lasts for many years since specific IgE was detectable in some patients after more than 8 years from the allergic episode. Specific IgE monitoring showed that specific IgE titres increase in some allergic patients and that allergen contamination of fishery products can account for the observed increase in Anisakis spp.-specific IgE level. Following sensitization to Anisakis spp. allergens, the absence of additional exposure to those allergens does not result in the loss of IgE sensitization. Exposure to Anisakis spp. allergens in fishery products can increase the specific IgE level in some sensitized patients." }, { "id": "pubmed23n0570_10172", "title": "Sensitization to the fish parasite Anisakis simplex: clinical and laboratory aspects.", "score": 0.0115777194517352, "content": "Hypersensitivity to Anisakis simplex is a worldwide medical problem. The parasite larvae die after freezing or cooking, but the tolerance of sensitized subjects to eating frozen fish remains a matter of controversy with contradictory findings. The aim of this study was to test if intolerance to properly cooked/frozen fish was due to the recognition of a particular allergen. Sixty-four patients with Anisakis simplex sensitization were studied by an IgE multiblot using simultaneously five different antigenic extracts. The antigens tested were a crude extract, excretory/secretory allergens, a heated extract, and two gradient ethanol precipitates of the crude extract. Intolerance was reported by 20% of the patients and was not related to the detection of any special allergen, nor to total or specific IgE levels. Intolerant patients only reported a higher frequency of digestive symptoms than the patients who tolerated fish ingestion. The most sensitive immunoblot antigen source was the 50-66% ethanol fraction of a crude extract (10x concentrated) that was found to be positive in 100% of the samples. Interestingly, 95% sensitivity in the IgE-immunoblot assay could be achieved using only two allergens, Ani s 1 and Ani s 4.

The correct answer is the first one. It is a typical picture of infectious mononucleosis. Although a similar picture may occur in acute toxoplasmosis, less than 1% of acute toxoplasma infections present as mononucleosis. Characteristic of Epstein-Barr infectious mononucleosis is the appearance of macular rash after treatment with amoxicillin.

A 17-year-old woman came to the emergency department with acute symptoms of high fever, pharyngeal pain and cervical lymphadenopathy. She had previously been diagnosed with acute pharyngitis and was treated with amoxicillin, and later presented with a generalized macular skin rash. Laboratory tests showed slight leukocytosis and presence of activated leukocytes, slight thrombopenia and slightly increased transaminases. What would be the most likely diagnosis of this clinical picture?

Ten within normal subjects were taken as controls. The patients were grouped on histopathological basis into 5 groups: (1) One (6%) of the cases was non-specific lymphadenitis diagnosed by clinical examination of the scalp and leucocytosis with polymorphonuclear predominance. (2) Reactive lymphadenitis included 6 (38%) of the cases. Infectious mononucleosis cases were diagnosed by clinical triad of fever, pharyngitis and cervical lymphadenopathy, relative lymphocytosis, monocytosis and positive monospot test. Cytomegalovirus case was diagnosed by lymphocytosis, monocytosis and negative monospot test. Toxoplasmosis cases were diagnosed by monocytosis, negative tuberculin test and positive indirect fluorescent antibody test. (3) Granulomatous lymphadenitis comprised 6 (3%) of the cases. Tuberculous cases were diagnosed by high ESR and highly positive tuberculin test. Sarcoidosis cases were diagnosed by negative tuberculin test and presence of hilar lymphadenopathy.

The patient also reported a nonproductive cough, coryza, and fatigue. The patient's only risk factor for HIV infection was a history of unprotected intercourse with 5 girls. Physical examination was significant for fever, exudative tonsillopharyngitis, shotty cervical lymphadenopathy, and palpable purpura on both feet. Laboratory studies demonstrated lymphopenia and mild thrombocytopenia. Hemoglobin, serum creatinine, and urinalysis were normal. The following day, the patient remained febrile. Physical examination revealed oral ulcerations, conjunctivitis, and erythematous papules on the thorax; the purpura was unchanged. Serologies for hepatitis B, syphilis, HIV, and Epstein-Barr virus were negative. Bacterial cultures of blood and stool and viral cultures of throat and conjunctiva showed no pathogens. Coagulation profile and liver enzymes were normal. Within 1 week, all symptoms had resolved. The platelet count normalized. Repeat HIV serology was positive, as was HIV DNA polymerase chain reaction. Subsequent HIV viral load was 350 000, and the CD4 lymphocyte count was 351/mm3. HIV is the seventh leading cause of death among people aged 15 to 24 in the United States, and up to half of all new infections occur in adolescents. Our patient presented with many of the typical signs and symptoms of acute HIV infection: fever, fatigue, rash, pharyngitis, lymphadenopathy, oral ulcers, emesis, and diarrhea. Other symptoms commonly reported include headache, myalgias, arthralgias, aseptic meningitis, peripheral neuropathy, thrush, weight loss, night sweats, and genital ulcers. Common seroconversion laboratory findings include leukopenia, thrombocytopenia, and elevated transaminases. The suspicion of acute HIV illness should prompt virologic and serologic analysis. Initial serology is usually negative. Diagnosis therefore depends on direct detection of the virus, by assay of viral load (HIV RNA), DNA polymerase chain reaction, or p24 antigen. Both false-positive and false-negative results for these tests have been reported, further complicating early diagnosis. Pediatricians should play an active role in identifying HIV-infected patients. Our case, the first report of acute HIV illness in an adolescent, emphasizes that clinicians should consider acute HIV seroconversion in the appropriate setting. Recognition of acute HIV syndrome is especially important for improving prognosis and limiting transmission. It is imperative that we maintain a high index of suspicion as primary care physicians for adolescents who present with a viral syndrome and appropriate risk factors." }, { "id": "pubmed23n0498_10724", "title": "Infectious disease capsules: a pox on your house.", "score": 0.014909997831273043, "content": "A 31-year-old, previously healthy white man presented to the emergency department with complaints of malaise, fevers, shortness of breath, a non-productive cough, and a \"rash.\" His physical exam revealed a temperature of 100.2F, a pulse of 129 bpm, respiratory rate of 14 BPM, and blood pressure of 140/74 mm Hg.

It is a benign lymphoproliferative, usually self-limiting disease. Complications are relatively rare, but they may occur, especially hematological.

Deuteration of white blood cells is rather rare, whereas mild neutropenia is a normal finding during the course of acute disease. On the other hand, agranulocytosis is extremely rate, and almost every case has been reported in the literature. Filgrastim--the recombinant human granulocyte colony-stimulating factor (G-CSF) stimulates the activation, proliferation and maturation of progenitor granulocyte cells. This drug is usually applied in treatment of iatrogenic neutropenia, during chemotherapy of malignancies and in some idiopathic and cyclic neutopenias. A female patient, 18 years of age, has been hospitalized at the Clinic of Infectious Diseases in Novi Sad on two occasions. First because of severe acute infectious mononucleosis with acute hepatitis and jaundice 10 days after onset of symptoms. Physical examination revealed severe intoxication, dehydration, icteric skin, mucosis and massive hepatosplenomegaly. The diagnosis was confirmed by ELISA IgM, EBV VCA positive and ELISA IgG EBV VCA and IgG EBVNA negative results. The patient was discharged from hospital after 24 days without complaints and with normal physical and laboratory findings. For several days she felt well, but gradually severe fatigue and malaise occurred and she became febrile again. That was the reason why she was hospitalized again, two weeks later. This time she was febrile, extremely intoxicated with general lymphadenopathy, catarrhal gingivostomatitis and massive splenomegaly. The first laboratory findings showed severe neutropenia (absolute count of granulocytes was 0.156 x 10/l, with only 12% segmented neutrophils). Mild anemia--3.05 x 10/l was also registered, while the platelet count was normal. Other biochemical analyses were normal, the Coombs' test negative, while the serological response was also normal. Bone marrow puncture was performed and normocellular bone marrow was registered, somewhere hypercellular due to hyperplasia of granulocyte progenitor cells from promyelocytes to normal maturated cells. Anemia showed megaloblastoid proliferation, while megakaryocytes were normal. High doses of corticosteroids were applied (dexamethasone 160 mg daily) and filgrastim 5 micrograms every other day. From the very beginning of therapy the patient felt better, whereas granulocytes responded with elevation as soon as 48 hours after initiation of therapy. On the sixth day the treatment was stopped because the level of granulocytes was normal and the patient has completely recovered. She was discharged from hospital 4 weeks later with mild meteorism, but normal physical and laboratory findings and mild splenomegaly registered only by ultrasonography.

When the patient's history was questioned again, it was learned that she had a tick on her neck about three weeks ago and she had removed the tick herself; 4-5 days later she had the complaints of fever and flu like symptoms and also diarrhea complaints lasting for 3-4 days. Considering the current anamnesis and laboratory findings, the patient was thought to have CCHF and the patient was isolated. The serum sample taken from patient with an initial diagnosis of CCHF and sent to Department of Microbiology Reference Laboratory Public Health Agency of Turkey. The patient was referred to the Antalya Training and Research Hospital. The patient's CCHF serum result was positive. Ribavirin treatment was not initiated in the patient who was accepted to be in the convalescence period, piperacillin-tazobactam 4 x 4.5 g/day treatment was continued and supportive treatment was given. In the follow-up, as the patient's neutropenia, thrombocytopenia and lymphocytopenia still continuing, she was transferred to hematology clinic for malignancy examination and bone marrow biopsy performed by hematology and B cell ALL was diagnosed. She was accepted to be convalescent in terms of CCHF and chemotherapy was started for ALL treatment by hematology. The patient is still being followed up by the hematology clinic and allogenic hematopoietic stem cell tranplantation is planned for the patient.

Most cases of IM are caused by the Epstein-Barr virus (EBV) or Cytomegalovirus (CMV). However, it is difficult to diagnose IM only with subjective symptoms, and thus EBV and CMV are nearly indistinguishable in clinical practice. A 20-year-old healthy Japanese woman had a 2-day history of high fever and consulted us. She had sex for the first time 6 months earlier. Her virus antibodies showed that she was infected with primary CMV. About 5 months later, she again experienced high fever and lymph node enlargement at the posterior cervical region. Her virus antibodies showed that she was infected with primary EBV at that time. Herein, we report a healthy adult Japanese woman with primary EBV infection relatively soon after primary CMV infection. It is very interesting to compare the symptoms and/or clinical data after EBV and CMV infection in the same patient within a short period of time. Our patient was diagnosed based only on subjective symptoms, physical examination and laboratory data, without tests of such virus-related antibodies. Therefore, clinicians should bear in mind that primary EBV infection and/or primary CMV infection is possible when patients have symptoms such as high fever, pharyngitis and lymphadenopathy, even in healthy adults." } ] } } }

An 85-year-old woman consults for fatigue and weakness especially in the mornings. She is sometimes unsteady when walking and has to sit down to regain her balance. On two occasions she has had to sit down to keep from falling but denies symptoms of dizziness. She has arterial hypertension, urinary incontinence and osteoarthritis. Her treatment is hydrochlorothiazide (25 mg/d), oxybutynin (10 mg/d), lisinopril (10 mg/d), calcium (1500 mg/d) and paracetamol (3 g/d). On examination he has a blood pressure of 115/70 mm Hg, pulse 80 bpm. His movements are slow. He has a moderate hand tremor. She can get up from the chair slowly but without needing to lean on her arms. She walks slightly leaning forward with little swinging of the arms. Turns slowly but without losing balance. She is unable to stand on one foot. Which of the following possible actions would you perform first?

This is the first detail report of Japanese cases. An endocrinological test and rhythm analyses of ambulatory blood pressure (ABP) and heart rate variability in a case suggested possible association between hypnic headache and hypothalamic-pituitary dysfunction. Case 1: A 48-year-old female migraineur complained of new-onset nocturnal headaches. Her headache awakened her from sleep between 1 AM and 2 AM. The headache occurred 3-4 times per week and lasted from 1 hour to 2 hours. The headache were moderate intensity and bilateral dull throbbing pain that located in the forehead to temples. There was no accompanying symptoms such as nausea, phonophobia, photophobia, nor the other autonomic features including conjunctival injection or tearing during the headache attacks. Physical and neurological examinations showed normal results except slight weakness and mild dysesthesia of the left arm due to a vertebral disk herniation at C5/6 level. In the pituitary endocrinological test, the prolactin level remarkably increased in response to the TRH loading. The single cosinor analysis demonstrated significant circadian rhythm of ABP parameters. However, the analysis did not demonstrate any significant circadian rhythm of Holter ECG parameters of time domain analysis and frequency analysis. Receiving 200 mg lithium bicarbonate before sleep, her nocturnal headache completely disappeared. Case 2: A 68-year-old woman had been followed up by her chronic tension-type headache since her forties. At her 66-years, she suffered from a new nocturnal headache. She awoke from sleep by the headache about 3 AM and the headache lasted 30 min. Moderate, dull headache located on her left temple to parietal head, 3-4 times/week. She was able to go back asleep without any medication after spontaneous headache cessation. She first complained the nocturnal headache at the 10 months later of the new headache appearance. She received 200 mg caffeine just before sleep and her headache has been disappeared. Case 3: 70-year-old women had been regularly visited our clinics for her migraine and chronic tension-type headache. She received amitriptyline and her headaches was well controlled. At her 69 years, she complained nocturnal headache. It occured every other day. The headache was moderate pulsative dull pain on the occipital region and lasted 90 minutes without any autonomic symptoms. Headache began between midnight and 1 AM. She told us her new nocturnal headache one year later of the onset. Oral caffeine (200 mg) just before sleep did not improve her headache and caused insomnia. Receiving 100 mg lithium before sleep, her hypnic headache disappeared completely. These three cases are compatible with the diagnostic criteria proposed in ICHD-II. There were some patients with hypnic headache in Japan and neurologists should pay attentions to this form of benign headache, because some beneficial treatments are currently available." }, { "id": "Neurology_Adams_4215", "title": "Neurology_Adams", "score": 0.01003851791253366, "content": "These are among the simplest and most important tests of autonomic function and most laboratories have automated techniques to quantitate them.

She was oriented to all spheres, however, she was somewhat bradyphrenic and had some disturbance in recent memory. Higher cerebral functions appeared intact. The visual acuity and visual fields were normal as were the optic fundi. Pupils were round and isocoric reacting promptly to light. Ocular movement was full, however, horizontal nystagmus was noted upon right lateral gaze. The sensation of the face was intact. She showed right facial paresis of the central type. Hearing was intact. She showed slurred speech and some difficulty in swallowing. The tongue was deviated to the right. Her gait was wide based and unsteady; tandem gait was difficult, however, walking on toes and on heels were performed well. No cerebellar ataxia was noted, but she showed some clumsiness in her right hand. Deep reflexes were symmetric and normally reactive; plantar response was extensor bilaterally. Sensation was intact; no meningeal sign was elicited. Routine laboratory work up was unremarkable; the CSF was under a borderline pressure (180 mmH2O) and contained 39 mg/dl of protein and 59 mg/dl of sugar. Cranial CT scan revealed diffuse low density areas involving bilateral cerebral white matter as well as the brain stem; MRI revealed high signal intensity lesions in those areas; gadolinium enhancement was negative; cortical sulci were effaced and the anterior part of the left lateral ventricle was compressed without deviation of the midline structure. The patient was treated with steroid pulse therapy without effect. She was discharged for out patient follow up, however, she developed a convulsion which was followed by loss of consciousness, and was admitted again to our service. She had never gained consciousness after this episode, and remained in the state of akinetic mutism. Follow-up CT and MRI did not show much change, although the area of high signal density lesions slightly enlarged on June 1, 1993. Her clinical course was complicated by drug induced bone marrow suppression and nephrotic syndrome. She expired on September 8, 1993 after developing sudden drop of blood pressure and bradycardia.(ABSTRACT TRUNCATED AT 400 WORDS)" }, { "id": "pubmed23n0050_7158", "title": "Orthostatic reactions in the 85-year olds.", "score": 0.009433962264150943, "content": "Testing of the orthostatic reaction is recommended in the examination of elderly fallers. This test usually includes blood pressure and instantaneous heart rate measurement but is difficult to perform in very elderly people according to the guidelines suggested for younger subjects. One reason for this is that old people often stand up slowly. The use of a tilt table, which enables a rapid change in posture from recumbent to erect position, is tempting as it could provide a method for a better standardized test. To study the usefulness of the tilt table as well as the degree of orthostatic reaction in the very elderly, we examined a sample of 85-year olds who did not suffer from falls. All were tested both with the tilt table and with active rising. The drop in blood pressure was equal in the two test types, but the increase in heart rate was significantly larger in active rising. Many test subjects were afraid of the tilt table, and two developed cardiac arrhythmia, i.e., atrial fibrillation, during the test. In our opinion, active rising is the method of choice in old persons. While the test subjects were in unusually good health for their age and thus could provide a suitable reference group for this test, the systolic blood pressure dropped considerably in several during the test. Criteria and indexes developed for younger subjects are not useful, and different evaluation criteria should be developed for the very elderly." }, { "id": "pubmed23n0800_14851", "title": "Breathlessness with pulmonary metastases: a multimodal approach.", "score": 0.009345794392523364, "content": "Case Study  Sarah is a 58-year-old breast cancer survivor, social worker, and health-care administrator at a long-term care facility. She lives with her husband and enjoys gardening and reading. She has two grown children and three grandchildren who live approximately 180 miles away. SECOND CANCER DIAGNOSIS  One morning while showering, Sarah detected a painless quarter-sized lump on her inner thigh. While she thought it was unusual, she felt it would probably go away. One month later, she felt the lump again; she thought that it had grown, so she scheduled a visit with her primary care physician. A CT scan revealed a 6.2-cm soft-tissue mass in the left groin. She was referred to an oncologic surgeon and underwent an excision of the groin mass. Pathology revealed a grade 3 malignant melanoma. She was later tested and found to have BRAF-negative status. Following her recovery from surgery, Sarah was further evaluated with an MRI scan of the brain, which was negative, and a PET scan, which revealed two nodules in the left lung. As Sarah had attended a cancer support group during her breast cancer treatment in the past, she decided to go back to the group when she learned of her melanoma diagnosis. While the treatment options for her lung lesions included interleukin-2, ipilimumab (Yervoy), temozolomide, dacarbazine, a clinical trial, or radiosurgery, Sarah's oncologist felt that ipilimumab or radiosurgery would be the best course of action. She shared with her support group that she was ambivalent about this decision, as she had experienced profound fatigue and nausea with chemotherapy during her past treatment for breast cancer. She eventually opted to undergo stereotactic radiosurgery. DISEASE RECURRENCE  After the radiosurgery, Sarah was followed every 2 months. She complained of shortness of breath about 2 weeks prior to each follow-up visit. Each time her chest x-ray was normal, and she eventually believed that her breathlessness was anxiety-related. Unfortunately, Sarah's 1-year follow-up exam revealed a 2 cm × 3 cm mass in her left lung, for which she had a surgical wedge resection. Her complaints of shortness of breath increased following the surgery and occurred most often with anxiety, heat, and gardening activities, especially when she needed to bend over. Sarah also complained of a burning \"pins and needles\" sensation at the surgical chest wall site that was bothersome and would wake her up at night. Sarah met with the nurse practitioner in the symptom management clinic to discuss her concerns. Upon physical examination, observable signs of breathlessness were lacking, and oxygen saturation remained stable at 94%, but Sarah rated her breathlessness as 7 on the 0 to 10 Borg scale. The nurse practitioner prescribed duloxetine to help manage the surgical site neuropathic pain and to assist with anxiety, which in turn could possibly improve Sarah's breathlessness. Several nonpharmacologic modalities for breathlessness were also recommended: using a fan directed toward her face, working in the garden in the early morning when the weather is cooler, gardening in containers that are at eye level to avoid the need to bend down, and performing relaxation exercises with pursed lip breathing to relieve anxiety-provoked breathlessness. One month later, Sarah reported relief of her anxiety; she stated that the fan directed toward her face helped most when she started to feel \"air hungry.\" She rated her breathlessness at 4/10 on the Borg scale. SECOND RECURRENCE: MULTIPLE PULMONARY NODULES  Sarah's chest x-rays remained clear for 6 months, but she developed a chronic cough shortly before the 9-month exam. An x-ray revealed several bilateral lung lesions and growth in the area of the previously resected lung nodule. Systemic therapy was recommended, and she underwent two cycles of ipilimumab. Sarah's cough and breathlessness worsened, she developed colitis, and she decided to stop therapy after the third cycle. In addition, her coughing spells triggered bronchospasms that resulted in severe anxiety, panic attacks, and air hunger. She rated her breathlessness at 10/10 on the Borg scale during these episodes. She found communication difficult due to the cough and began to isolate herself. She continued to attend the support group weekly but had difficulty participating in conversation due to her cough. Sarah was seen in the symptom management clinic every 2 weeks or more often as needed. No acute distress was present at the beginning of each visit, but when Sarah began to talk about her symptoms and fear of dying, her shortness of breath and anxiety increased. The symptom management nurse practitioner treated the suspected underlying cause of the breathlessness and prescribed oral lorazepam (0.5 to 1 mg every 6 hours) for anxiety and codeine cough syrup for the cough. Opioids were initiated for chest wall pain and to control the breathlessness. Controlled-release oxycodone was started at 10 mg every 12 hours with a breakthrough pain (BTP) dose of 5 mg every 2 hours as needed for breathlessness or pain. Sarah noted improvement in her symptoms and reported a Borg scale rating of 5/10. Oxygen therapy was attempted, but subjective improvement in Sarah's breathlessness was lacking. END OF LIFE  Sarah's disease progressed to the liver, and she began experiencing more notable signs of breathlessness: nasal flaring, tachycardia, and restlessness. Opioid doses were titrated over the course of 3 months to oxycodone (40 mg every 12 hours) with a BTP dose of 10 to 15 mg every 2 hours as needed, but her breathlessness caused significant distress, which she rated 8/10. The oxycodone was rotated to IV morphine continuous infusion with patient-controlled analgesia (PCA) that was delivered through her implantable port. This combination allowed Sarah to depress the PCA as needed and achieve immediate control of her dyspneic episodes. Oral lorazepam was also continued as needed. Sarah's daughter moved home to take care of her mother, and hospice became involved for end-of-life care. As Sarah became less responsive, nurses maintained doses of morphine for control of pain and breathlessness and used a respiratory distress observation scale to assess for breathlessness since Sarah could no longer self-report. A bolus PCA dose of morphine was administered by Sarah's daughter if her mother appeared to be in distress. Sarah died peacefully in her home without signs of distress.

The positive results of intervention against high blood pressure in the elderly has resulted in a positive attitude towards treatment and today this is an accepted and highly effective medical intervention. Both stroke and coronary morbidity have been shown to be positively affected as has total mortality. The specific issue, how far to lower blood pressure in the elderly was probably best addressed in the Hypertension Optimal Treatment (HOT) stduy in which about a third of the patients, i.e. &gt;6,000 patients, were &gt; or =65 years of age. In most of the early intervention studies of antihypertensive treatment in elderly patients diuretics or beta-blockers or the two in combination were used as the therapy by which blood pressure was lowered. However, novel therapies, in particular calcium antagonists, have shown benefits of the same magnitude as the older therapies, e.g. in the STONE trial, the Syst-Eur study, the Syst-China study and the STOP-Hypertension-2 study. In the latter study a regimen based on either of two ACE inhibitors was also shown to be equally effective as conventional treatment, based on diuretics and/or betablockers, in the elderly. These trials will be briefly reviewed here as will the SCOPE study which is an ogoing trial in which hypertensive patients aged 70-89 years are being treated with an angiotensin II receptor antagonist under double-blind and placebo-controlled conditions. It can be concluded that a wealth of information, based on large intervention trials, has been accumulated during the last decade. It is quite obvious that the elderly hypertensive patients benefit from antihypertensive treatment to at least the same extent as the young and middle-aged. It appears that blood pressure ought to be lowered down to normotensive values also in the elderly in order to minimize their risk if cardiovascular complications, although more studies would be welcome to address this issue specifically in the elderly." }, { "id": "pubmed23n0404_1932", "title": "Nefopam abuse.", "score": 0.009259259259259259, "content": "To report 3 patients who abused nefopam, a central analgesic that inhibits serotonin, norepinephrine, and dopamine reuptake.

He experienced violent behavior, agitation, facial dysesthesia and myoclonus, tremor of fingers, and sweating. He did not attempt withdrawal. The patients described above are drug-dependent according to the Diagnostic and Statistical Manual, 4th Edition. All patients developed a pharmacodynamic tolerance phenomenon, which can develop rapidly. Violent behavior, tremor after massive intake, and depressive symptoms during withdrawal are similar to those reported with psychostimulant abuse.

Increased morbidity and mortality from stroke and heart attack, and incomplete correction with treatment have been interpreted as suggesting further benefit from aggressive reduction of BP to 'normal' in all patients. 4. The emergence of powerful drugs with few side-effects, and the promise of lowering office BP to 'normal' as monotherapy, has removed the hesitation to treat 'mild' hypertension. 5.

In 1997, she was admitted to our hospital. On admission, the patient was disoriented but able to follow simple verbal commands, to name things, and to write simple words. Neither apraxia, aphasia, hemispatial neglect, nor a corpus callosum disconnection syndrome was observed. There was no muscle weakness or atrophy. She showed a positive Babinski sign with mild spasticity in the legs and Gegenhalten, but no rigidity. Her speech was monotonous and abnormally fast (cluttering-like speech). Her speech became faster and faster toward the end of sentences, skipping several syllables or even words. She was unable to speak slowly and clearly, even when efforts were made to pace her speech to the speed set by the examiner. She was able to stand only with a wide base of support and body flexion. When standing, she was unable to place one foot directly beside the other; as she tried to have one foot near the other, the former repelled the latter. She had great difficulties in taking her first step forward, and showed rapid freezing of gait even when she managed to succeed in starting. She was able to imitate walking or bicycling with her legs unloaded, indicating that her gait disturbance was a kind of apraxia of gait. Her intelligence was somehow difficult to assess because of her peculiar speech disturbance. However, her family members had noticed her memory disturbance and personality change (offensiveness) since 3 to 4 years before the admission. Moreover, she was defective not only on Hasegawa Damentia Scale-Revised but also on Raven's Colored Progressive Matrices which estimates non-verbal intelligence. It was also noted that she was inattentive and lazy in thinking on questionnaires. Thus we considered that she was at least mildly demented and the type of dementia was of frontal pathology.

While receiving regularly weekly transcortical treatments with AC pulsed EMFs in the picotesla range intensity she experienced during the first year improvement in mental functions, return of strength in the upper extremities, and recovery of trunk control. During the second year she experienced the return of more hip functions and recovery of motor functions began in her legs. For the first time in years she can now initiate dorsiflexion of her ankles and actively extend her knees voluntarily. Over the past year she started to show signs of redevelopment of reciprocal gait. Presently, with enough function restored in her legs, she is learning to walk with a walker and is able to stand unassisted and maintain her balance for a few minutes. She also regained about 80% of functions in the upper limbs and hands. Most remarkably, there was no further progression of the disease during the 4 years course of magnetic therapy. This patient's clinical recovery cannot be explained on the basis of a spontaneous remission. It is suggested that pulsed applications of picotesla EMFs affect the neurobiological and immunological mechanisms underlying the pathogenesis of CP MS." }, { "id": "pubmed23n0053_20225", "title": "[Shy-Drager syndrome and the syndrome of inappropriate secretion of antidiuretic hormone].", "score": 0.008849557522123894, "content": "We report a 52-year-old male patient with Shy-Drager syndrome (SDS) complicated by an occurrence of the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). The patient first developed impotence at the age of 48, accompanied by urinary incontinence, and episodes of dizziness while standing. The following year, the patient had developed a staggering gait and speech became monotonous. At age 52, the patient was admitted to the hospital after experiencing frequent episodes of syncope associated with complete loss of consciousness. Upon examination, blood pressure was 100/70 in a recumbent position, and 80/60 when standing. The pulse rate varied from 60 per minute to 62. The patient was alert. The alternating Horner sign was observed, and a paucity of facial movements was visible. His speech was slow and monotonous. Muscle tone was increased bilaterally. There was incoordination. A laboratory examination revealed reduced serum sodium levels of 127 mEq/L and increased sodium excretion with plasma hypoosmolality (262 mOsm/kg/H), urine hyperosmolality and low serum renin activity (0.2 ng/ml/h). Renal functions were normal and the levels of adrenocortical and thyroid hormones were normal. There were no abnormalities observed in the chest roentgenogram taken. The level of antidiuretic hormone (ADH) was unreasonably high (5.74 pg/ml). A water-load test demonstrated failure of both water diuresis and inhibition of ADH secretion. These data suggested that hyponatremia in this case was caused by SIADH. The correlation between plasma osmolality and the concentration of ADH suggested that osmolality that initiates ADH release appeared to have been reset to around 230 mOsm/kg lower than normal.(ABSTRACT TRUNCATED AT 250 WORDS)" }, { "id": "pubmed23n0797_22175", "title": "Efficacy and tolerability of delapril plus indapamide versus lisinopril plus hydrochlorothiazide combination treatments in mild to moderate hypertension: a multicenter, randomized clinical study.", "score": 0.008771929824561403, "content": "Several studies have shown that antihypertensive monotherapy is commonly insufficient to control blood pressure (BP) in hypertensive patients and that concomitant use of ≥2 drugs is necessary in ∼50% of these patients. The combination of an angiotensin-converting enzyme (ACE) inhibitor and a diuretic, delapril plus indapamide (D + I), has been shown to be effective and tolerable, with no interaction between the 2 components. Another widely used combination of ACE inhibitor and diuretic is lisinopril plus hydrochlorothiazide (L + H). The aims of this study were to confirm the antihypertensive efficacy and tolerability of the fixed combination of D + I in mild to moderate hypertension, and to compare its therapeutic efficacy and tolerability with that of L + H. The antihypertensive efficacy and tolerability of a fixed combination of D + I (30-mg + 2.5-mg tablets once daily) or L + H (20-mg + 12.5-mg tablets once daily) in patients with mild to moderate hypertension were compared in a multinational, multicenter, randomized, 2-armed, parallel-group study. Eligible patients were aged 18 to 75 years and had a diastolic blood pressure (DBP) 95 to 115 mm Hg and a systolic blood pressure (SBP) ≤180 mm Hg, both measured in the sitting position. After a single-blind, placebo run-in period of 2 weeks, patients were randomized to receive 1 of the 2 treatments for a 12-week period. The primary efficacy end point was the BP normalization rate (ie, the percentage of patients with a sitting DBP ≤90 mm Hg) after 12 weeks of treatment. Secondary end points were as follows: (1) the responder rate (ie, the percentage of patients whose sitting DBP was reduced by ≥10 mm Hg from baseline or had a DBP ≤90 mm Hg after 12 weeks of treatment), (2) the percentage of patients with a DBP ≤85 mm Hg, and (3) changes in sitting SBP and DBP after 4, 8, and 12 weeks of treatment. A total of 159 hypertensive patients (88 women, 71 men) were randomized to receive D + I (44 women, 36 men; mean [SD] age, 53 [(11)] years) or L + H (44 women, 35 men; mean [SD] age, 55 [(10)] years). No significant between-group differences were found in any of the primary or secondary end points of the study. Both combinations induced a significant reduction in sitting DBP and SBP from baseline (P&lt;0.001 for both groups at week 12), without significant differences between the groups. Five mild to moderate adverse drug reactions (ADRs) occurred in each treatment group. No patient dropped out of the study because of an ADR.

In about 5% of the group, moreover, the falls were in excess of 40 mm Hg. Our investigations in 160 residents in an old people's home in the age range 59-88 years largely confirmed Caird's figures. Using Schellong's test we recorded systolic pressure falls of 20 mm Hg and more in 25% of our subjects. These cases of circulatory dysregulation were all manifestations of the hypodynamic form of the orthostatic syndrome. This means that only systolic blood pressure fell, diastolic pressure as well as heart rate being largely unaffected. The phenomenon appears to be due to age-related deterioration in circulatory regulation; at least no evidence has been found to suggest that it has a specific aetiology. In a double-blind cross-over study the effect of dihydroergotamine (DHE) was compared to placebo in 40 patients. Half the patients were given 2 mg DHE three times daily for 14 days and the other half placebo tablets; following 1 week's wash-out, the treatments were then reversed for a further 2-week period. Schellong's test (measurement of blood pressure and pulse after 10 min in the supine position and then after 1, 2, 5 and 10 min standing) was performed at the beginning and end of each treatment period. The average falls in upright systolic pressure for all 40 patients were as follows: before treatment 20 mm Hg (150 leads to 130); end of placebo period 19 mm Hg (147 leads to 128); end of DHE periods 7 mm Hg (145 leads to 138). The differences between the values recorded after treatment with DHE and the other two values are statistically significant (p less than 0.05). Similarly there was a significant difference in the numbers of patients experiencing dizziness during Schellong's test (16-17 out of 40 patients before treatment and after placebo, 6 out of 38 patients after DHE). From this finding conclusions can be drawn regarding the causes of vertigo in old age." } ] } } }

On the occasion of her fourth delivery by cesarean section, bilateral cystical formations in both ovaries were found. Upon ending the delivery, the right ovary with the cyst was surgically removed, as well as part of the cystically changed left ovary. The pathohistological analysis of the samples taken from the left ovary cyst pointed to the following diagnosis: dermoid cyst of the ovary a mature cystic teratoma, whereas the samples from the cystic tumor of the right ovary were diagnosed as: ovarian teratoma malignant a papillary carcinoma of the thyroid tissue and cystadenoma papillare serosum ovarii. The histological type of the malignant thyroid tissue neoplasm in the teratoma was a papillary carcinoma consisting of papillary proliferations lined by cuboidal, cylindrical and pseudostratified epithelium with charasteristic \"ground glass\" nuclei, but without invasion into the blood vessels. Malignant transformation of the ectopic thyroid tissue, which is one of the elements of the ovarian cystic teratoma, is extremely rare: it is diagnosed on basis of the histological picture and criteria which are the same as for the tumor of the thyroid gland. One should not exclude a pssibility that the identical or different pathological alterations characteristic of the thyroid gland may also be detected in the ectopic thyroid tissue of a dermoid cyst. The reported case was chosen due to its complex and rich clinical and pathohistological picture characterized by the occurrence of a bilateral dermoid cyst with the malignant transformation of the thyroid tissue. The malignant neoplasm in the mature ovarian cystic teratoma was papillary carcinoma of the thyroid tissue with all histological properties typical for the thyroid gland carcinoma. The possibility of the malignant transformation of the endodermal thyroid tissue in the mature ovarian cystic teratoma and changes in the thyroid gland of the Basedow's disease type diagnosed before are without clear causation." }, { "id": "pubmed23n0602_9674", "title": "Adenocarcinoma arising from respiratory ciliated epithelium in benign cystic teratoma of the ovary: a case report with analyzes of the CT, MRI, and pathological findings.", "score": 0.013638638638638638, "content": "The malignant transformation of mature cystic teratoma is rare, thus occurring in only 1-2% of all cases.

They commonly are found in the sacrococcygeal-gonadal location, sometimes in midline locations such as the mediastinum, retroperitoneum, and head and neck region. Primary rectal teratomas are extremely rare. Extragonadal teratomas can originate from pluripotent germ cells present in abnormal embryonic rests. CASE REPORT Here, we report a rare case of a primary mature, solid teratoma of the rectum. A 68-year-old woman presented with hematochezia and denied any history of abdominal pain or a change in bowel habits. Colonoscopy revealed a 4-cm pedunculated polyp in the rectum. No hair was present on its surface. The polyp was completely removed by polypectomy. Histologically, the tumor consisted of mature components from all 3 germ layers. Its surface was covered by squamous epithelium with hair follicles and sweat glands. Adipose tissue, blood vessels, bone, and glandular epithelium were present inside the mass. No evidence was found of immature elements or malignant features. CONCLUSIONS When polypoid lesions are found in the rectum, teratoma should be considered in the differential diagnosis. Histopathological confirmation is necessary to diagnose teratoma. Primary rectal teratomas should be distinguished from other neoplastic polyps as well as from local spread of teratomas arising in adjacent organs. These neoplasms are usually mature (benign) but may undergo malignant transformation. Therefore, complete resection is recommended to alleviate symptoms and avoid the risk of malignancy." }, { "id": "pubmed23n0016_922", "title": "[Mature benign teratomas with malignant tumors and malignant monodermal ovarian teratomas.

The age of the patients was 44--76 years. The first 8 observations included 6 epidermoid carcinomas, 1 undifferentiated carcinoma and 1 strumal carcinoid. In the epidermoid carcinomas malignancy was recognized peroperatively only in three instances. One tumor had infiltrated the broad ligament on one side and another the urinary bladder. The neoplasm appeared as a mass which thickened the wall of a typical dermoid cyst. Four patients died of the tumor from 3 months to 1 year after operation; one is alive more than 19 years later and one is lost to follow-up. The crucial factor in prognosis is the integrity of the ovarian capsule. The undifferentiated carcinoma, which had infiltrated the pelvic walls, could only be incompletely resected and caused death within 3 1/2 months. The strumal carcinoid was discovered by chance during laparotomy for a far-advanced adenocarcinoma of the pancreas which led to death within 2 months. The two cases of malignant monodermal teratoma comprised 1 thyroid papillary carcinoma and 1 carcinoid. Both patients are alive more than 8 and 5 years after operation.

This bacterium has a peculiar antibiotic resistance profile. It is resistant to most of the antibiotics against gram-negative bacteria and susceptible to antibiotics that are used to treat gram-positive bacteria, such as vancomycin and trimethoprim-sulphamethoxazole (SXT). For this reason appropriate treatment of E.meningosepticum infections are based on the proper identification of bacteria. In this report, a case of catheter-related E.meningosepticum bacteremia in a patient with chronic renal failure due to Bardet-Biedl syndrome, a genetic disorder characterized by multiorgan dysfunction, was presented. A 25-year-old male patient with Bardet-Biedl syndrome was admitted to the emergency room with the complaints of high fever with shivers that started the day before. The patient had a femoral dialysis catheter. Venous blood samples drawn at the time of administration were cultured immediately. Two days later, blood cultures which yielded positive signals were passaged onto blood and MacConkey agar plates and after incubation at 37°C for 16 hours, wet-raised colonies with clear margin, gray colour and large size similar to gram-negative bacterial colonies were detected on blood agar medium. No growth was observed on MacConkey agar plate at the end of five days. The isolate was found positive for KOH, oxidase, catalase, urease, esculine and MOI (Motility Indole Ornithine) tests, whereas it was citrate negative. Gram staining revealed faintly stained thin gram-negative bacilli. The isolate was identified as E.meningosepticum by Vitek® 2 system (bioMérieux, USA), and confirmed by sequence analysis of 16S RNA gene region amplified with PCR method. The antibiotic susceptibility profile of the strain was detected by the Vitek 2 system, while vancomycin susceptibility was investigated by Kirby-Bauer disc diffusion method. The isolate was found resistant to ampicillin/sulbactam, piperacillin/tazobactam, ceftazidime, cefepime, meropenem, imipenem, amikacin, gentamicin, netilmicin, levofloxacin, tetracycline, colistin and rifampicin; intermediate to tigecyclin and tetracyclin; susceptible to cefoperazone/sulbactam, ciprofloxacin, levofloxacin, SXT and vancomycin. One gram vancomycin once every four days was administered to the patient, however on the ninth day of the treatment he developed fever again. Blood cultures obtained again yielded E.meningosepticum. After changing his dialysis catheter and extending the vancomycin treatment to 15 days, the patient was discharged with cure. In conclusion, clinicians should consider E.meningosepticum as a possible causative agent of bacteremia non-responsive to the empirical antibiotic regimens and when gram-negative bacteria are isolated from the blood cultures of such patients with underlying diseases. Accurate and prompt identification of E.meningosepticum will allow immediate administration of the specific antibiotic treatment, thereby decreasing the mortality and morbidity rates.

Metastatic infection develops in up to one-third of patients with SAB, with joints and heart valves being the most commonly affected sites. Community-acquisition,persistent fever, positive blood cultures after 48 h of treatment and the presence of embolic lesions correlate with the presence of complicated SAB (i.e. high risk of endocarditis and/or other metastatic complications). All patients require careful clinical evaluation to exclude endocarditis and other metastatic foci. Echocardiography,preferably transoesophageal echocardiography, should be performed to exclude endocarditis. Most patients with SAB, and all with features of complicated SAB, require prolonged intravenous antibiotic therapy (at least 4 weeks), but a subgroup with good prognostic features may be suitable for shorter intravenous therapy (2 weeks). Penicillinase-resistant penicillins (e.g.flucloxacillin) are the agents of choice for SAB with methicillin-sensitive strains. Vancomycin or first-generation cephalosporins are alternatives but have lower antimicrobial activity than flucloxacillin.

We report here a case of CA-MRSA meningitis complicated by acute left middle cerebral artery (MCA) infarction and necrotizing pneumonia in a previously healthy 1-month-old Vietnamese boy. He was firstly treated with vancomycin, but changed to linezolid because of persistent fever and low vancomycin trough level. He recovered successfully with residual right-sided hemiparesis. The mode of transmission of CA-MRSA and the mechanism of cerebral infarction (thrombotic or embolic) were unknown. The isolate was genotyped as staphylococcal cassette chromosome (SCC) mec type V with a novel sequence type (ST) 5959 harboring the Panton-Valentine leukocidin (PVL) gene. ST 5959 is a double locus variant of ST 59, which is a major PVL-positive CA-MRSA strain isolated in invasive disease in Asian countries. This case report may serve as a warning about the dissemination of PVL-positive CA-MRSA in and around Japan, with the possibility of causing serious life-threatening disease.

Recently, molecular methods are recommended for the accurate identification of S.uberis isolates. The aim of this report is to present a lower respiratory tract infection case caused by S.uberis and the microbiological methods for identification of this bacterium. A 66-year-old male patient with squamous cell lung cancer who received radiotherapy was admitted in our hospital for the control. According to the chest X-Ray, patient was hospitalized with the prediagnosis of ''cavitary tumor, pulmonary abscess''. In the first day of the hospitalization, blood and sputum cultures were drawn. Blood culture was negative, however, Candida albicans was isolated in the sputum culture and it was estimated to be due to oral lesions. After two weeks from the hospitalization, sputum sample was taken from the patient since he had abnormal respiratory sounds and cough complaint. In the Gram stained smear of the sputum there were abundant leucocytes and gram-positive cocci, and S.uberis was isolated in both 5% sheep blood and chocolate agar media. Bacterial identification and antibiotic susceptibility tests were performed by VITEK 2 (Biomerieux, France) and also, the bacterium was identified by matrix assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) based VITEK MS system as S.uberis. The isolate was determined susceptible to ampicillin, erythromycin, clindamycin, levofloxacin, linezolid, penicillin, cefotaxime, ceftriaxone, tetracycline and vancomycin. 16S, 23S ribosomal RNA and 16S-23S intergenic spacer gene regions were amplified with specific primers and partial DNA sequence analysis of 16S rRNA polymerase chain reaction (PCR) products were performed by 3500xL Genetic Analyzer (Applied Biosystems, USA). According to the partial 16S rRNA gene sequencing results, bacterium was confirmed as S.uberis. This report makes a significant contribution to the number of case reports of human infections caused by S.uberis as the identification was performed by current microbiological methods in our case. In conclusion, S.uberis should be evaluated as an opportunistic pathogen among the immunosuppressed patients and in addition to phenotypic bacteriological methods, the other recent microbiological methods should also be utilized for the identification." }, { "id": "pubmed23n1152_16962", "title": "The First Case Report of Community-Acquired Infective Endocarditis Due to Sequence Type 1223 <i>Staphylococcus argenteus</i> Complicated with Convexity Subarachnoid Hemorrhage.", "score": 0.00909090909090909, "content": "<iStaphylococcus argenteus</i is a new species classified as part of the <iStaphylococcus aureus</i-related complex in 2015 and has been recognized to be as pathogenic as <iS. aureus</i.

In this report, a case of brain abscess due to MRSA which did not respond neither to moxifloxacin + vancomycin nor vancomycin + rifampin combination therapies, and merely treated by linezolid + rifampin combination, has been presented. Fifty-one years old female patient who was operated 40 days ago for subarachnoid bleeding and aneurysm in middle cerebral artery bifurcation, was hospitalized due to purulent leakage from the operation area. She did not have fever and her physical examination, including the neurologic system, was normal. Computerized tomography revealed an approximately 1 cm lesion compatible with subdural empyema and cerebral abscess in the right frontoparietal area in supratentorial sections. The patient was operated for wound revision and moxifloxacin was initiated. Since the operation materials revealed MRSA growth, vancomycin (4 x 500 mg, IV) was added to the treatment. The isolate was identified by conventional methods, and antibiotic susceptibility test performed by disk diffusion method showed that it was susceptible to levofloxacin, linezolid, rifampin, vancomycin and teicoplanin. Since no clinical response was obtained in two weeks, moxifloxacin was switched to rifampin (300 mg 1 x 2). On the 10th day of vancomycin + rifampin therapy, radiological findings showed development of cerebritis and therefore vancomycin was changed with linezolid (2 x 600 mg, IV). The control CT of the patient revealed regression of the brain lesion and linezolid + rifampin treatment continued for six weeks. The patient did not develop any hematological, liver or renal toxicity during the therapy and the radiological findings regressed. No relapse were detected in the one year follow-up period.

An 87-year-old woman presented with a 1-year history of forgetfulness that was aggravated since the past 2 months. She had a long-term history of multiple major conditions, including hypertension, diabetes, osteoporosis, and arterial plaques. Brain imaging showed age-related changes, and her Mini Mental State Examination score was 20. Other tests revealed no abnormalities apart from multiple thyroid nodules on ultrasonography. She was diagnosed with AD, hypertension, type 2 diabetes mellitus, diabetic neuropathy, osteoporosis, carotid and lower-extremity arterial plaques, thyroid nodules. She was treated with donepezil (5 mg/day), amlodipine besylate (5 mg/day), glimepiride (4 mg/day), methylcobalamin (1.5 mg/day), calcium carbonate D3 (600 mg/day), simvastatin (20 mg/day) and enteric-coated aspirin (100 mg/day). Four days later, she experienced fatigue, panic, sweating, and one episode of vomiting. On the 5th day, she developed increased muscle tension, speech difficulty, and involuntary tremors. Imaging and blood tests revealed no obvious abnormality, and the patient was not receiving psychotropic drugs. An extrapyramidal adverse reaction to donepezil was considered, and the drug was discontinued, after which the symptoms gradually disappeared. Serious adverse reactions to donepezil can occur in elderly patients, who typically require multiple medications for a variety of comorbidities. In particular, extrapyramidal reactions have occurred when donepezil is administered in combination with psychotropic drugs. However, in our patient, an extrapyramidal adverse reaction occurred in the absence of psychotropic drugs. Thus, clinicians must be aware of inter-individual differences in drug actions and possible serious adverse reactions, and carefully monitor these patients to ensure the timely detection of adverse events and their safe treatment." }, { "id": "wiki20220301en291_41931", "title": "Levodopa-induced dyskinesia", "score": 0.009900990099009901, "content": "Nicotine (administered by dermal adhesive patches) has also been shown to improve Levodopa-induced dyskinesia and other PD symptoms.

The list of drugs able to induce parkinsonism is long and probably incomplete, because new drugs, with previously unknown antidopaminergic activity, are constantly being added. Not all the drugs have the same potency for inducing parkinsonism. We classify these drugs in three groups: (1) drugs with obvious antidopaminergic activity which regularly induce parkinsonism; (2) drugs able to induce parkinsonism in particular individuals and (3) drugs which may aggravate Parkinson's disease treated with levodopa. The reports of isolated cases of parkinsonism induced by widely-used drugs (drugs in group 2) may be the result of either an idiosyncratic side effect or a misdiagnosis of parkinsonism. The antidopaminergic activity of the drugs of this group is weak and not sufficiently demonstrated. Maybe, in these cases, the blockage of other neurotransmitters different from dopamine plays a role in the induction of parkinsonism. Probably, the number of patients with DIP is higher than reported or detected, because many patients suffer from weak symptoms that quickly disappear after drug withdrawal. One of the main points of interest is knowing the list, because all these drugs, specially those of group 1, should be avoided or used with caution in the treatment of some common symptomatic problems in patients with Parkinson's disease, such as depression, arterial hypertension, diabetes mellitus and cardiac disorders.

Midway between these two time points, in 1938, L: -dopa decarboxylase was discovered, the enzyme that produces dopamine (DA) from levodopa. In 1957, DA was shown to occur in the brain, and in 1959 it was found to be enriched in the basal ganglia. At that time the striatal localization of DA, together with studies done in 1957-58 in naive and reserpine-treated animals regarding DA in the brain and the central effects of levodopa, suggested its possible involvement in \"extrapyramidal control\" and \"reserpine parkinsonism\". Following these discoveries, a study of (postmortem) brains of patients with basal ganglia disorders, including PD, was started, demonstrating, in 1960, a severe striatal DA deficit specifically in PD, thus furnishing a rational basis for the concept of \"DA replacement therapy\" with levodopa. Accordingly, in 1961, the first highly successful clinical trial with i.v. levodopa was carried out. In 1963, the DA deficit in the PD substantia nigra was found, indicative of a nigrostriatal DA pathway in the human brain, subsequently established in animal studies in 1964-65. In 1967, the chronic, high dose oral levodopa regimen was introduced in treatment of PD. Besides the above highlights in the history of levodopa, the article also cites critical opinions of world authorities in brain research of the time, harmful to the cause of DA, levodopa and PD.

In patients with mild head injury (Glasgow Coma Scale score = 13-15), the likelihood of intracranial abnormality, as defined by cranial computed tomography (CT), varies according to presenting neurologic signs and symptoms. This prospective study consisted of 152 patients with blunt head trauma and one or more of the following: initial loss of consciousness (LOC), headache, vomiting, convulsions, or amnesia. All underwent cranial CT within one hour of presentation. Positive CT findings were defined as cerebral contusion, extra-axial hematoma, intra-ventricular or subarachnoid hemorrhage, brain edema, and skull fracture. Clinical findings were tabulated and compared with CT findings. The most common symptoms were headache (61%) followed by followed by LOC (45%), vomiting (39%), amnesia (29%), and convulsions (4%). Convulsions were the most predictive of a CT positive finding (80%); history of LOC was least predictive (29%). The presence of two or more clinical findings tended to increase the likelihood of intracranial abnormality, but the association was neither consistent nor additive. Convulsions occurring in a patient with mild head injury are highly predictive of a positive intracranial finding on CT. Headache, amnesia, and vomiting are each likely to show positive findings in approximately 40-45% of cases. Although the least predictive of the neurologic findings studied, loss of consciousness still correlates with a positive cranial CT in 29% of cases. More than one sign or symptom increases the likelihood of concurrent brain injury." }, { "id": "pubmed23n0286_14268", "title": "Minor head trauma: Is computed tomography always necessary?", "score": 0.017284495439835245, "content": "To determine the clinical value of routine computed tomography (CT) of the head in patients with normal mental status after minor head trauma.

To evaluate the risk of deterioration in MHI, and 6. To find out whether patients with normal neurological examination and normal CT can be safely discharged. In a prospective study conducted over a period of four months in our center, all patients with mild head injury (defined as Glasgow Coma Scores (GCS) 13-15) were admitted to the head injury unit. Patients underwent standard clinical examination, skull radiography and cranial CT. No clinical criteria were used to select patients for CT scanning and all the patients were subjected to CT. Patients with negative findings on CT and a normal neurological examination were discharged after 24 hours of observation. Patients with positive findings on cranial CT were treated either medically or surgically as deemed necessary. Outcome measures included safe discharge, clinical deterioration, need for surgical intervention or death. The following factors were analyzed statistically to find out whether they can be used as predictive factors for positive cranial CT. They were: age, sex, mode of injury, loss of consciousness, post-traumatic seizures, ear/ nose/throat bleeding, vomiting, admission GCS score, scalp injury, polytrauma, focal neurological deficit, fractures visualized on skull radiography. Three hundred and eighty one patients were included in the study. Of these males constituted 63%, females 17% and children 20%. RTA was the most common mode of injury. Seventy five percent of the patients had GCS of 15, 15% had GCS of 14 and 10% had GCS of 13. Thirty eight percent of the patients had positive findings on the CT. Age, mode of injury, loss of consciousness, post-traumatic seizures, ENT bleeding, vomiting, scalp injury and polytrauma were not found to be predictors of positive CT. Admission GCS score, focal neurological deficits, and fractures detected by skull radiography were found to be statistically significant predictors of positive findings on CT. Seven percent of patients required surgical intervention. Six percent of patients showed neurological deterioration and there was one death in this series of MHI patients. Patients with multiple lesions on CT had a higher chance of deterioration than those with a single lesion. No patient who had a GCS of 15 and normal CT developed any complication during the hospital stay or after discharge. The incidence of positive CT scans in this prospective, consecutive, unselected cohort of MHI patients was 38%. Lower admission GCS scores, focal neurological deficits, and fractures detected by skull x-rays were found to be significant predictors of positive CT. Other clinical parameters were not found to be predictors of positive CT. CT was found to be superior to plain x-rays in detecting skull fractures. Seven percent of this cohort required neurosurgical intervention. Six percent showed neurological deterioration and there was one death in this series. Patients with multiple lesions on CT had a higher chance of deterioration than those with single lesions. The duration of hospital stay was prolonged in patients with positive CT.

Normal examination increased the probability of a normal computed tomography scan from.87 pretest to.90 posttest. Four of 38 subjects with normal examination were noted to have evidence of intracranial injury on computed tomography. These four subjects did not require neurosurgical intervention. Two of 98 subjects underwent neurosurgical procedures. One intracranial pressure monitor was placed for decreasing level of consciousness. One subject underwent surgical elevation of a depressed skull fracture.

Of 686 such patients with cranial computed tomography (CT) scans, scan results were recorded, along with total and motor components of the Glasgow Coma Scale (GCS) and the Reaction Level Scale (RLS85). Despite relatively normal admission neurological examinations, 127 of the 689 patients (18.4%) had intracranial lesions, and 38 (5.5%) required surgery. There was no significant difference in distribution of the GCS in patients with and without intracranial lesions. The RLS85 was superior to the GCS in predicting intracranial pathology, and a significant association between RLS85 and lesions on CT scanning was noted. However, even this test was normal in 19 patients found to have intracranial pathology, including nine who required surgery. The authors conclude that a normal or near-normal mental status examination in a head-injured patient on arrival at the emergency room is inadequate to exclude a potentially serious intracranial lesion. It is unlikely that further refinements in the clinical evaluation will result in diagnostic accuracy comparable with that of CT scanning. Accordingly, we recommend that any patient who has suffered a loss of consciousness or amnesia following head injury have an urgent cranial CT scan." }, { "id": "pubmed23n0563_13312", "title": "Indications for brain CT scan in patients with minor head injury.", "score": 0.016447590158409166, "content": "Minor head injury is the most common type of head injury.

In all cases clinical signs and symptoms were collected and a cranial computerized tomography (CT) scan was obtained. The relationship between the occurrence of clinical findings and appearance of intracranial posttraumatic lesions on cranial CT was analyzed by chi-square tests and statistic logistic regression methods, with 95% confidence intervals. Of 682 patients, 46 (6.7%) presented brain injuries on CT scan. All patients with abnormal CT scans had at least one of the following factors (risk factors): posttraumatic amnesia, loss of consciousness, posttraumatic seizure, headache, vomiting, focal neurological deficit, skull fracture, coagulopathy or antecedent of treatment with anticoagulants and patient age older than 60 years. No abnormal CT scans were found among patients without any of those risk factors on admission. Vomiting, skull fracture and age greater than 60 years were risk factors significantly correlated to an abnormal cranial CT after head injury.

Variables reviewed were mental status, neurological examination, presence or absence of loss of consciousness, clinical evidence of basilar skull fracture, and fracture on skull radiography. The neurological examination (including mental status and Glasgow coma scale) in the emergency room was the best predictor of subsequent deterioration or the presence of an operative hematoma. The only patients with Glasgow coma scale scores of 15 who required surgical evacuation of an extraaxial hematoma had focal neurological deficits referable to hemispheric compression, with or without an abnormal mental status. A Glasgow coma scale score of 13 or 14 places the patient at risk either of having a hematoma requiring surgery or of deteriorating. We recommend that a head CT scan be obtained on all patients with Glasgow coma scale scores of less than 15, abnormal mental status, or hemispheric neurological deficits.

A single-dose of intramuscular benzathine penicillin has been the mainstay of treatment for yaws. However, intramuscular injections are painful and pose safety and logistical constraints in the poor areas where yaws occurs. A single center randomized control trial (RCT) carried out in Papua New Guinea in 2012 demonstrated the efficacy of a single-dose of oral azithromycin for the treatment of yaws. In this study, we also compared the efficacy of a single oral dose of azithromycin as an alternative to intramuscular benzathine penicillin for the treatment of the disease in another geographic setting. We conducted an open-label, randomized non-inferiority trial in three neighboring yaws-endemic districts in Southern Ghana. Children aged 1-15 years with yaws lesions were assigned to receive either 30mg/kg of oral azithromycin or 50,000 units/kg of intramuscular benzathine penicillin. The primary end point was clinical cure rate, defined as a complete or partial resolution of lesions 3 weeks after treatment. The secondary endpoint was serological cure, defined as at least a 4-fold decline in baseline RPR titre 6 months after treatment. Non- inferiority of azithromycin treatment was determined if the upper bound limit of a 2 sided 95% CI was less than 10%.

Although intramuscular benzathine penicillin (bicillin) 1.2 million units (MU) every 4 weeks is widely used for secondary prophylaxis, studies in other countries have shown a recurrence rate of 3-8% over 5-6 years in patients on this regimen. It has been recommended that serum penicillin concentrations should be maintained above 0.02 mg/ml to prevent such recurrences. The World Health Organisation (WHO) and the American Heart Association have recommended since 1988 that patients in high-risk areas for the development of rheumatic fever should receive benzathine penicillin 1.2 MU every 3 weeks rather than every 4. The aims of this study were, firstly, to determine the prevalence of serum penicillin concentrations below 0.02 micrograms/ml in rheumatic fever patients on benzathine penicillin 1.2 MU 4-weekly and, secondly, to study the effect of increasing the dose of 1.8 MU 4-weekly in patients with subtherapeutic concentrations.

Review of our present policy of secondary prophylaxis for rheumatic fever is necessary. Concentrated preparations of benzathine penicillin (600,000 U/ml) are not available in South Africa; administration of a higher dose (1.8 MU) 4-weekly would therefore require a double injection, which could affect compliance adversely.

The aim of this study was to measure temporal trends in incidence and risk factors for IPD (defined as culture of Streptococcus pneumoniae from blood, cerebrospinal fluid or both) in a cohort of HIV-positive patients attending an ambulatory HIV care centre in Dublin, Ireland over a 10-year period 2006-2015. Incidence of IPD was determined as events per 100,000 person-years' follow-up. Poisson regression was used to assess linear trend in incidence over time. A nested case-control study (four controls per case) was undertaken to assess risk factors for IPD. Forty-seven episodes of IPD were identified in 42 HIV-positive individuals (median [IQR] age 38 years [33-43], 69% male, 86% injecting drug users (IDUs), median CD4 T-cell count 213 cells/mm<sup3</sup) over 16,008 person-years' follow-up (overall incidence rate 293/100,000 person-years).

It is now known that the incidence can be reduced by prophylactic measures and/or the use of vaccines. HIV infection produces an elevated frequency of severe pneumococcal disease with a rate of bacteriemia caused by Streptococcus pneumoniae 150-300 fold greater than rates reported in non-HIV infected people. For this reason, pneumococcal vaccine should be administered as early as possible in the course of the infection. Besides, the antibody response may be significantly higher for asymptomatic persons. Acute hepatitis caused by hepatitis B virus is milder than in non HIV infected patients but chronic disease is more frequent. The prognosis is worse and there is higher risk for infecting another persons. Hepatitis B vaccine is indicated for all the patients with HIV and negative serology for hepatitis B virus. Influenza vaccine is of limited effectiveness due to the high variability of the virus. Besides, influenza incidence is low among approximately young adults, HIV related immunodeficiency increased influenza risk only minimally, the vaccine is administered yearly and HIV-replication can increase in temporal association with vaccination. For all these reasons, fewer hospitalizations and deaths are prevented making it a far less cost-effective prevention strategy than pneumococcal vaccination. The risk of Haemophilus influenzae infections is elevated, but the vaccine is not routinely recommended because the more frequent serotype in HIV infected patients is b. For these subjects, passive immunization with immunoglobulin may also be necessary to provide protection. In conclusion, pneumococcal and hepatitis B vaccination is a reasonable prevention strategy for HIV infected patients at all stages of immunodeficiency.

CDC recommends vaccinations for adults on the basis of age, health conditions, prior vaccinations, and other considerations. Updated vaccination recommendations from CDC are published annually in the U.S. Adult Immunization Schedule. Despite longstanding recommendations for use of many vaccines, vaccination coverage among U.S. adults remains low. August 2017-June 2018 (for influenza vaccination) and January-December 2018 (for pneumococcal, herpes zoster, tetanus and diphtheria [Td]/tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis [Tdap], hepatitis A, hepatitis B, and human papillomavirus [HPV] vaccination). The National Health Interview Survey (NHIS) is a continuous, cross-sectional national household survey of the noninstitutionalized U.S. civilian population. In-person interviews are conducted throughout the year in a probability sample of households, and NHIS data are compiled and released annually. NHIS's objective is to monitor the health of the U.S. population and provide estimates of health indicators, health care use and access, and health-related behaviors. Adult receipt of influenza, pneumococcal, herpes zoster, Td/Tdap, hepatitis A, hepatitis B, and at least 1 dose of HPV vaccines was assessed. Estimates were derived for a new composite adult vaccination quality measure and by selected demographic and access-to-care characteristics (e.g., age, race/ethnicity, indication for vaccination, travel history [travel to countries where hepatitis infections are endemic], health insurance status, contacts with physicians, nativity, and citizenship). Trends in adult vaccination were assessed during 2010-2018. Coverage for the adult age-appropriate composite measure was low in all age groups. Racial and ethnic differences in coverage persisted for all vaccinations, with lower coverage for most vaccinations among non-White compared with non-Hispanic White adults. Linear trend tests indicated coverage increased from 2010 to 2018 for most vaccines in this report. Few adults aged ≥19 years had received all age-appropriate vaccines, including influenza vaccination, regardless of whether inclusion of Tdap (13.5%) or inclusion of any tetanus toxoid-containing vaccine (20.2%) receipt was measured. Coverage among adults for influenza vaccination during the 2017-18 season (46.1%) was similar to the estimate for the 2016-17 season (45.4%), and coverage for pneumococcal (adults aged ≥65 years [69.0%]), herpes zoster (adults aged ≥50 years and aged ≥60 years [24.1% and 34.5%, respectively]), tetanus (adults aged ≥19 years [62.9%]), Tdap (adults aged ≥19 years [31.2%]), hepatitis A (adults aged ≥19 years [11.9%]), and HPV (females aged 19-26 years [52.8%]) vaccination in 2018 were similar to the estimates for 2017. Hepatitis B vaccination coverage among adults aged ≥19 years and health care personnel (HCP) aged ≥19 years increased 4.2 and 6.7 percentage points to 30.0% and 67.2%, respectively, from 2017. HPV vaccination coverage among males aged 19-26 years increased 5.2 percentage points to 26.3% from the 2017 estimate. Overall, HPV vaccination coverage among females aged 19-26 years did not increase, but coverage among Hispanic females aged 19-26 years increased 10.8 percentage points to 49.6% from the 2017 estimate. Coverage for the following vaccines was lower among adults without health insurance compared with those with health insurance: influenza vaccine (among adults aged ≥19 years, 19-49 years, and 50-64 years), pneumococcal vaccine (among adults aged 19-64 years at increased risk), Td vaccine (among all age groups), Tdap vaccine (among adults aged ≥19 years and 19-64 years), hepatitis A vaccine (among adults aged ≥19 years overall and among travelers aged ≥19 years), hepatitis B vaccine (among adults aged ≥19 years and 19-49 years and among travelers aged ≥19 years), herpes zoster vaccine (among adults aged ≥60 years), and HPV vaccine (among males and females aged 19-26 years). Adults who reported having a usual place for health care generally reported receipt of recommended vaccinations more often than those who did not have such a place, regardless of whether they had health insurance. Vaccination coverage was higher among adults reporting ≥1 physician contact during the preceding year compared with those who had not visited a physician during the preceding year, regardless of whether they had health insurance. Even among adults who had health insurance and ≥10 physician contacts during the preceding year, depending on the vaccine, 20.1%-87.5% reported not having received vaccinations that were recommended either for all persons or for those with specific indications. Overall, vaccination coverage among U.S.-born adults was significantly higher than that of foreign-born adults, including influenza vaccination (aged ≥19 years), pneumococcal vaccination (all ages), tetanus vaccination (all ages), Tdap vaccination (all ages), hepatitis B vaccination (aged ≥19 years and 19-49 years and travelers aged ≥19 years), herpes zoster vaccination (all ages), and HPV vaccination among females aged 19-26 years. Vaccination coverage also varied by citizenship status and years living in the United States. NHIS data indicate that many adults remain unprotected against vaccine-preventable diseases. Coverage for the adult age-appropriate composite measures was low in all age groups. Individual adult vaccination coverage remained low as well, but modest gains occurred in vaccination coverage for hepatitis B (among adults aged ≥19 years and HCP aged ≥19 years), and HPV (among males aged 19-26 years and Hispanic females aged 19-26 years). Coverage for other vaccines and groups with Advisory Committee on Immunization Practices vaccination indications did not improve from 2017. Although HPV vaccination coverage among males aged 19-26 years and Hispanic females aged 19-26 years increased, approximately 50% of females aged 19-26 years and 70% of males aged 19-26 years remained unvaccinated. Racial/ethnic vaccination differences persisted for routinely recommended adult vaccines. Having health insurance coverage, having a usual place for health care, and having ≥1 physician contacts during the preceding 12 months were associated with higher vaccination coverage; however, these factors alone were not associated with optimal adult vaccination coverage, and findings indicate missed opportunities to vaccinate remained. Substantial improvement in adult vaccination uptake is needed to reduce the burden of vaccine-preventable diseases. Following the Standards for Adult Immunization Practice (https://www.cdc.gov/vaccines/hcp/adults/for-practice/standards/index.html), all providers should routinely assess adults' vaccination status at every clinical encounter, strongly recommend appropriate vaccines, either offer needed vaccines or refer their patients to another provider who can administer the needed vaccines, and document vaccinations received by their patients in an immunization information system." }, { "id": "pubmed23n1135_2009", "title": "Implementation of EACS vaccination recommendations among people living with HIV.", "score": 0.009615384615384616, "content": "With modern combination antiretroviral Treatment (cART) a normal life expectancy among people living with HIV (PLWH) has become reality if started early enough prior to the onset of more pronounced immunodeficiency.

A chart review of 200 HIV-infected patients diagnosed was conducted to determine shortcomings in previous practice and determine which vaccines should routinely be given in specialist HIV clinics and which might be able to be delegated to primary care clinics. Data were collected on administration of three categories of vaccinations: (1) vaccines used in all individuals with chronic disease (pneumococcal, influenza, swine flu H1N1); (2) targeted vaccinations used in non-immune individuals with HIV who are at risk of exposure (hepatitis A and hepatitis B); (3) routine vaccines traditionally delivered to the whole population (measles/mumps/rubella [MMR], diphtheria/tetanus/pertussis and meningitis C/ACWY). Pneumococcal vaccine was delivered to 54% of eligible patients, 52% of eligible individuals completed a full hepatitis B programme of vaccination and 21% (42/200) were naturally immune; hepatitis A vaccine was delivered to 36% of eligible individuals. With increasing demands on resources, it seems likely that HIV services will have to harness resources of primary care in vaccine programmes in relation to routine vaccines. By improving communication between primary and secondary care mistakes with live vaccination decisions could be avoided; HIV services should continue to perform targeted and chronic disease vaccines, i.e. for category 1 and category 2 vaccines." } ] } } }

Difficult question in which the correct answer could give rise to discussion. The patient is a 16-year-old male who is admitted for a fairly clear case of mononucleosis due to EBV infection that becomes complicated during admission. The data available to us are: - Pancytopenia. - Hepatopathy. - Coagulopathy. - Absence of infectious focus: negative blood cultures, negative urine cultures, normal X-ray, normal CSF. - CRP and Ferritin elevated / normal Procalcitonin. The possible complications that could have occurred (and that are considered in the answers) are sepsis or a bad evolution of mononucleosis. The clinical data could be consistent with a septic process, however, the main infectious foci have been reasonably ruled out and one of the most sensitive and specific markers of bacteremia (procalcitonin) is in the normal range, which should draw our attention.

It is a benign lymphoproliferative, usually self-limiting disease. Complications are relatively rare, but they may occur, especially hematological. Most common are autoimmune hematolytic anemia and thrombocytopenia, and they respond to corticoid therapy. Deuteration of white blood cells is rather rare, whereas mild neutropenia is a normal finding during the course of acute disease. On the other hand, agranulocytosis is extremely rate, and almost every case has been reported in the literature. Filgrastim--the recombinant human granulocyte colony-stimulating factor (G-CSF) stimulates the activation, proliferation and maturation of progenitor granulocyte cells. This drug is usually applied in treatment of iatrogenic neutropenia, during chemotherapy of malignancies and in some idiopathic and cyclic neutopenias. A female patient, 18 years of age, has been hospitalized at the Clinic of Infectious Diseases in Novi Sad on two occasions. First because of severe acute infectious mononucleosis with acute hepatitis and jaundice 10 days after onset of symptoms. Physical examination revealed severe intoxication, dehydration, icteric skin, mucosis and massive hepatosplenomegaly. The diagnosis was confirmed by ELISA IgM, EBV VCA positive and ELISA IgG EBV VCA and IgG EBVNA negative results. The patient was discharged from hospital after 24 days without complaints and with normal physical and laboratory findings. For several days she felt well, but gradually severe fatigue and malaise occurred and she became febrile again. That was the reason why she was hospitalized again, two weeks later. This time she was febrile, extremely intoxicated with general lymphadenopathy, catarrhal gingivostomatitis and massive splenomegaly. The first laboratory findings showed severe neutropenia (absolute count of granulocytes was 0.156 x 10/l, with only 12% segmented neutrophils). Mild anemia--3.05 x 10/l was also registered, while the platelet count was normal. Other biochemical analyses were normal, the Coombs' test negative, while the serological response was also normal. Bone marrow puncture was performed and normocellular bone marrow was registered, somewhere hypercellular due to hyperplasia of granulocyte progenitor cells from promyelocytes to normal maturated cells. Anemia showed megaloblastoid proliferation, while megakaryocytes were normal. High doses of corticosteroids were applied (dexamethasone 160 mg daily) and filgrastim 5 micrograms every other day. From the very beginning of therapy the patient felt better, whereas granulocytes responded with elevation as soon as 48 hours after initiation of therapy. On the sixth day the treatment was stopped because the level of granulocytes was normal and the patient has completely recovered. She was discharged from hospital 4 weeks later with mild meteorism, but normal physical and laboratory findings and mild splenomegaly registered only by ultrasonography. During the last 10 years only several cases of severe leukopenia with acute infectious mononucleosis had been reported in literature. In all cases it was associated with some other hematological complications and it occurred in young adults without previously registered immunodeficiency. We have no knowledge about application of filgrastim in treatment of EBV-induced agranulocytosis, but the International Association for Studying Agranulocytosis and Aplastic Anemia reported that in 4% of patients Epstein-Barr virus can cause agranulocytosis even a year after the occurrence of acute disease." }, { "id": "pubmed23n0055_4833", "title": "[An autopsied case of chronic active Epstein-Barr virus (EBV) infection with various symptom].", "score": 0.018089960886571055, "content": "A 19-year-old boy, who complained of fever and fatigue was hospitalized in November 1986.

Blood and sputum cultures grew no microorganisms. Epstein-Barr virus-IgM, Cytomegalovirus-IgM and Mycoplasma pneumonia antibodies were all negative. Bone marrow aspiration and biopsy revealed histiocytosis with hemophagocytosis. No atypical histiocyte was found. The patient was put on dexamethasone treatment with improvement. Unfortunately, symptoms relapsed two weeks later. A repeated bone marrow aspiration and biopsy revealed a picture similar to the previous one. Despite antibiotic administration and ventilator support, a rapidly deteriorated course terminated in the patient's death by respiratory failure. Mosquito bite allergies were reported to be associated with malignant histiocytosis in Japan. However, atypical histiocytes were not found in our case upon repeated bone marrow aspirations, biopsies and skin biopsies. Mature histiocytes with hemophagocytosis were prominent instead. Reactive histiocytosis was thus favored rather than malignant histiocytosis. Although opportunistic infection cannot be excluded, we propose that a mosquito bite allergy with consequent histiocytic activation by antigen, immune complex or IgE is the possible pathogenetic mechanism for hemophagocytic histiocytosis in this patient." }, { "id": "pubmed23n1145_22242", "title": "A Case of Severe Epstein-Barr Virus-Associated Hemophagocytic Lymphohistiocytosis Successfully Treated With High Dose Steroids and Ganciclovir.", "score": 0.01595873786407767, "content": "Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening hematological disorder characterized by immune dysregulation with multiple organ involvement and carries a poor prognosis.

The etiology of Still's disease is unknown and the disease is characterized by fever episodes, a typical macular-papular exanthema, lymphadenopathy, hepatosplenomegaly, and arthralgias. A mild to moderate increase in liver enzymes is often found as part of this disease. Rarely, a fulminate liver failure has been described, particularly in the presence of co-administration of nonsteroidal antirheumatics or acetaminophen. Still's disease must be considered as part of the differential diagnosis of acute liver failure, because an early diagnosis and consequent therapy with prednisone may prevent the need for liver transplantation." }, { "id": "pubmed23n1032_10415", "title": "Hemophagocytic Lymphohistiocytosis in Renal Transplant Recipients: A 2-Case Report.", "score": 0.013615803563186559, "content": "Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome characterized by an excessive immune activation.

Herein we report a unique case of pharyngotonsillitis as an initial manifestation of disseminated HSV-2 infection without genital involvement. A 46-year-old male was admitted to our hospital with a 1-week history of fever and sore throat. His past medical history included hypereosinophilic syndrome diagnosed at age 45 years. Physical examination revealed throat congestion, bilaterally enlarged tonsils with exudates, tender cervical lymphadenopathy in the left posterior triangle, and mild epigastric tenderness. The laboratory data demonstrated bicytopenia, elevated liver enzyme levels, and hyperferritinemia. A bone marrow smear showed hypocellular marrow with histiocytes and hemophagocytosis. The diagnosis of HLH was confirmed, and the patient was treated with methylprednisolone pulse therapy on days 1-3.

Additional testing showed that he was positive for HSV-specific immunoglobulin M and immunoglobulin G. Disseminated HSV infection was suspected, and intravenous acyclovir (10 mg/kg every 8 h) was begun. A subsequent direct antigen test of a bulla sample was positive for HSV-2. Moreover, tonsillar and esophageal biopsies revealed viral inclusion bodies. Immunohistochemical staining and a quantitative real-time polymerase chain reaction (PCR) assay confirmed the presence of HSV-2. Disseminated HSV-2 infection with multiple bullae, tonsillitis, esophagitis, and suspected hepatic involvement was diagnosed.

It is not readily diagnosed after 1 week of intensive in-hospital testing or after intensive outpatient or inpatient testing. Fevers of unknown origin may be caused by infectious diseases, malignancies, collagen vascular diseases, or a variety of miscellaneous disorders. The relative distribution of causes of FUOs is partly age-related. In the elderly, the preponderance of FUOs is attributable to neoplastic and infectious etiologies, whereas in children, collagen vascular diseases, neoplasms, and viral infectious disease predominate. The diagnostic approach to FUOs depends on a careful analysis of the history, physical findings, and laboratory tests. Most patients with FUOs exhibit localizing findings that should direct the diagnostic workup and limit diagnostic possibilities. The most perplexing causes of FUOs involve those without specific diagnostic tests, e.g., juvenile rheumatoid arthritis (JRA) or adult Still's disease. In a young adult with FUO, if all of the cardinal symptoms are present, JRA may present either a straightforward or an elusive diagnosis, if key findings are absent or if the diagnosis goes unsuspected. We present a 19-year-old man with a recurrent FUO. His illness began 3 years before admission and has recurred twice since. In the past, he did not manifest arthralgias, arthritis, or a truncal rash. On admission, he presented with an FUO with hepatosplenomegaly, aseptic meningitis, and pericarditis. An extensive diagnostic workup ruled out lymphoma and leukemia. Moreover, a further extensive workup eliminated infectious causes of FUO appropriate to his clinical presentation, ie, tuberculosis, histoplasmosis, brucellosis, Q fever, typhoid fever, Epstein-Barr virus, infectious mononucleosis, cytomegalovirus, human herpes virus (HHV)-6, babesiosis, ehrlichiosis, viral hepatitis, and Whipple's disease. The diagnosis of JRA was based on the exclusion of infectious and neoplastic disorders in a young adult with hepatosplenomegaly, aseptic meningitis, pericarditis, and a double quotidian fever. With JRA, tests for rheumatic diseases are negative, as they were in this case. The only laboratory abnormalities in this patient included elevated serum transaminases, a mildly elevated erythrocyte sedimentation rate, and a moderately elevated level of serum ferritin. Diagnostic fever curves are most helpful in cases where the diagnosis is most elusive, as was the case here. Relatively few disorders are associated with a double quotidian fever, ie, visceral leishmaniasis, mixed malarial infections, right-sided gonococcal acute bacterial endocarditis, and JRA. Because the patient received antipyretics during the first week of admission, fever was not present.

Radiological diagnosis was lymphoma. Cell marker showed an excess of large granular lymphocytes and activated lymphocytes. The Glandular Fever Slide Test was positive. Subsequently, Paul Bunnell test was also positive. Epstein Barr virus serology was consistent with recent Epstein Barr virus infection. Antibiotic was omitted; enoxaparin was prescribed for pulmonary artery thrombosis. Learning points from this case: (1) Although routine administration of antibiotic to a spinal cord injury patient with pyrexia may be acceptable in outpatient setting, other possibilities such as infection by multi-drug resistant organism, viral infection, venous or, arterial thrombosis should be considered if a patient does not respond promptly to antibacterial therapy. (2) When full blood count showed lymphocytosis (comprising &gt; 50% of white blood cells) with atypical morphology, lymphocyte surface markers, Paul Bunnell test, and Epstein Barr virus serology should be performed. These tests would have led to a diagnosis of infectious mononucleosis, and abdominal imaging studies could have been avoided. (3) Lymphoid hyperplasia is the hallmark of infectious mononucleosis; therefore, we should have suspected glandular fever rather than lymphoma when CT scan revealed enlarged lymph nodes in abdomen, mediastinum, axillae and inguinal regions in this patient, who had lymphocytosis with atypical morphology. (4) A soft tissue mass, situated inferior to left hemidiaphragm in this asplenic patient, was misinterpreted as lymph nodes; review of CT led to the correct diagnosis of splenunculus. (5) Acute infection with Epstein Barr virus may lead to transient induction of anti-phospholipid antibodies, which can cause vascular thrombosis. (6) This case illustrates the value of reviewing test results and discussion with senior doctors, as these measures help to recognize medical errors and improve patient care." }, { "id": "pubmed23n0886_1375", "title": "What is that rash?", "score": 0.009523809523809525, "content": "A healthy 15-month-old girl presented to the emergency department with a 24-hour history of fever and rash.

Clinicopathological data of 39 patients with synchronous CRC and 528 patients with single CRC from May 1996 to June 2001 were reviewed retrospectively. The patients with synchronous CRC accounted for 6.9% of all the patients with colorectal carcinoma treated in our hospital during the same period. Compared with concurrent lesions, Dukes stage of the index lesions of synchronous CRC was more developed and the lymph node metastasis and vessel invasion occurred more frequently. In addition, it also had poorer differentiation. There were significant differences of Dukes stages and lymph node metastasis between the index lesions and single CRC. The incidence of adenomatous polyp in synchronous CRC was higher than that in single CRC(59.0% vs 25.0%,P&lt;0.01). The sensitivity of preoperative colonoscopy examination was 76.9%, which was significantly higher than that of barium examination and exploration during operation. The total 5-year survival rate of synchronous CRC was significantly lower than that of single CRC (5.1% vs 28.2%,P=0.042), and no significant difference of total 5-year survival rate was found between single CRC patients and synchronous CRC patients undergone radical operation. Synchronous CRC patients undergone radical operation had longer survival as compared to those undergone palliative operation(P&lt;0.01).

Surgery is therefore the first choice for management of these cancers even in cases where complete removal of the tumor is not expected, surgery is useful for the prolongation or improvement of the quality of life. However, the correct choice of operation for such cases is very important. The extent of resection and dissection must be decided based upon the degree of cancer spread. Both must be sufficient, but not excessive. In cases in the early stage where cancerous growth has not spread beyond the submucosal layer, local or segmental excision may be a good enough treatment. On the other hand, for far advanced rectal cancer involving adjacent organs, combined resection and pelvic evisceration is curatively effective. Several pathological findings of resected specimens influencing prognosis were investigated in the present study. In cases which appeared to be diffuse infiltrative spreading type in macroscopic appearance or poorly differentiated, undifferentiated, or mucinous types of cancer in their histological features, survival rates were low. However, these were uncommon and over half of them were much too far advanced to receive curative resection.

He denied any medical or surgical history, and physical examination revealed no perianal disease. He underwent preoperative chemoradiation therapy (CRT) consisting of a tegafur/gimeracil/oteracil potassium (S-1)-based regimen with 45 Gy of radiation. After completion of CRT, computed tomography (CT) revealed the primary tumor's partial response, but a liver mass highly suggestive of metastasis was detected. This mass was later diagnosed as cavernous hemangioma 3 months after CRT initiation. He then underwent and completed six cycles of consolidation chemotherapy with a capecitabine-based regimen. Subsequent colonoscopy revealed the complete response of the primary tumor, but CT showed thickening of the edematous rectal wall. Therefore, we planned to perform low anterior resection as a radical surgery. However, he presented with persistent anal pain after the last chemotherapy, and magnetic resonance imaging revealed a high-intensity mass behind the anus, suggestive of an anal fistula. We considered the differential diagnosis of a benign anal fistula or implantation metastasis into the anal fistula. Fistulectomy was performed, and a pathological diagnosis of tubular adenocarcinoma, suggestive of implantation metastasis, was made. Thereafter, we performed laparoscopic abdominoperineal resection.

The treatment of cancer of the colon is now clearly defined; intraoperative hepatic ultrasonography and histological examination of the resection specimen provide all of the necessary data in the majority of the cases.

The past medical history included chronic sinusitis, hypertension, and diabetes mellitus. A chest x-ray film and computed tomography showed multiple pulmonary nodules with cavities. Macrohematuria had developed 3 days before admission, and renal function had deteriorated (creatinine, 2.45 mg/dL) in 2 weeks. He was admitted to our hospital because of rapidly progressive glomerulonephritis (RPGN) and multiple pulmonary nodules. On admission, the clinical diagnosis was suspected to be granulomatosis with polyangiitis (Wegener's) (GPA), although tests for proteinase-3 anti-neutrophil cytoplasmic antibody (PR3-ANCA) were negative. Antibiotics were administered for 5 days. After renal biopsy, methylprednisolone pulse therapy and cyclophosphamide pulse therapy were performed. The pathological diagnosis on the basis of the renal biopsy was glomerular and interstitial hemorrhage, possibly associated with vasculitis. After the treatment, the pulmonary symptoms, multiple pulmonary nodules, and severe inflammatory reactions in the peripheral blood were resolved. However, renal dysfunction progressed to end-stage renal disease 1 month after renal biopsy. Hemodialysis was started, and the steroid therapy was continued. During hemodialysis, a second renal biopsy was performed and led to a diagnosis of pauci-immune focal segmental crescentic glomerulonephritis. Renal function gradually recovered, and hemodialysis was discontinued. This case was (double) ANCA-negative GPA which presented prominent glomerular and interstitial hemorrhage, may be associated with small vessel vasculitis, but without active necrotizing and crescentic glomerular lesions, in the rapidly progressive glomerulonephritis." }, { "id": "pubmed23n1047_6840", "title": "Eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome).", "score": 0.01738934056007227, "content": "Churg-Strauss syndrome, Eosinophilic granulomatosis with polyangiitis (EGPA), is a systemic vasculitis that affects small- to medium-sized vessels.

Recurrent vasculitis occurred with seven grafts (four patients with microscopic polyangiitis or Wegener's granulomatosis, two patients with Henoch-Schonlein purpura, and one patient thrombotic thrombocytopenic purpura). New-onset hematuria was the initial renal symptom in five patients. Treatment with corticosteroids, cyclophosphamide, and/or plasma exchange was most often effective, but two grafts were lost. Proteinase 3 ANCA titers were increased to 12-738 U/ml before seven transplants. The patient with the lowest titer lost his graft due to recurrence, two other patients had reversible recurrence after 1 year and 5 years, two patients lost their grafts due to unknown/unrelated causes, and two patients' grafts remain without recurrence. Myeloperoxidase ANCA were increased to 22-39 U/ml before two transplants, which have been uneventful for 4 years. An awareness of the small but perpetual risk of recurrence facilitates early treatment that may save the transplant.

We used enzyme-linked immunosorbent assays to examine retrospectively the relationship between ANCA concentration and disease activity in 56 patients with systemic vasculitis. We included patients with Wegener's granulomatosis, microscopic polyangiitis, idiopathic rapidly progressive glomerulonephritis, and Churg-Strauss syndrome, and examined separately the initial treatment period (mean length of follow-up, 26 months) and long-term management (mean length of follow-up, 59 months). Levels of ANCA decreased during induction therapy with prednisolone and cyclophosphamide, with or without plasma exchange. During follow-up, 27 relapses were documented in 20 patients (10 with Wegener's granulomatosis, nine with microscopic polyangiitis, and one with Churg-Strauss syndrome), occurring between 4 and 183 months (mean, 62 months) after initial presentation. Patients in whom ANCA were detectable 1 year or more after treatment were at particular risk of clinical relapse. Proteinase 3-directed ANCA appeared to be associated with a higher rate of relapse (44% of patients relapsed) than myeloperoxidase-directed ANCA (13% of patients relapsed). Twenty-four of the 27 relapses occurred in the presence of detectable ANCA; in 21 of these, ANCA concentration was high or rising. The temporal relationship between changes in ANCA concentration and clinical relapse varied considerably between patients; in seven patients, ANCA remained at high levels for many months (range, 14 to 67 months) before eventual relapse. One patient showed high concentrations of ANCA over a period of 11 years without relapse. In five patients, increases in the ANCA level were not temporally associated with relapse (although four of these patients relapsed on other occasions.) We conclude that monitoring ANCA by enzyme-linked immunosorbent assays is of value in the long-term management of patients with Wegener's granulomatosis, microscopic polyangiitis, idiopathic rapidly progressive glomerulonephritis, and Churg-Strauss syndrome. Increases in ANCA and persistently high levels point to the risk of relapse and indicate the need for frequent clinical review and continuing maintenance immunosuppression. However, our results suggest that ANCA assays should always be used in conjunction with other indices of disease activity and should not be the sole basis for changing therapy." }, { "id": "pubmed23n0753_13933", "title": "Pulmonary renal syndrome in a child with coexistence of anti-neutrophil cytoplasmic antibodies and anti-glomerular basement membrane disease: case report and literature review.", "score": 0.012727062362605577, "content": "Pulmonary renal syndrome (PRS), denoting the presence of diffuse alveolar hemorrhage and glomerulonephritis as manifestations of systemic autoimmune disease, is very rare in childhood.

We describe a child with PRS associated with both circulating anti-myeloperoxidase (anti-MPO) ANCA and anti-GBM disease on renal biopsy who was successfully treated with immunosuppressive therapy. A 10-year old girl presented with fever, fatigue, malaise, and pallor followed by hemoptysis and severe anemia. Diffuse alveolar hemorrhage was revealed on fiberoptic bronchoscopy. Renal findings consisted of microscopic hematuria, moderate proteinuria, and anti-GBM disease on renal biopsy. ANCA with anti-MPO specificity were present whereas anti-GBM antibodies were on borderline for positivity. Methyl-prednisolone pulses followed by prednisone led to cessation of hemoptysis, marked improvement of lung fuction, and normal finding on chest x-ray within 10 days.

HP caused by bacterial infection was thus likely and antibiotics, rifampicin and metronidazole, were administered orally as an outpatient. However, one month later, these symptoms were worsened with headache and double vision. He was then rehospitalized.

Disease activity was prospectively assessed and quantified by the Birmingham Vasculitis Activity Score. A total of 347 sera were analyzed for ANCA determination. Relapses occurred in 23 (54%) of 43 patients. Diagnostic category (Wegener's granulomatosis vs micropolyangiitis and renal-limited vasculitis), severity of initial symptoms (mean vasculitis activity score, mean number of organs involved), and ANCA pattern [cytoplasmic-ANCA (c-ANCA) vs perinuclear-ANCA (p-ANCA)] did not significantly differ between relapsers and nonrelapsers.

No past medical history was obtained and the only positive history was his travel from Afghanistan 2 days earlier, which he had given to emergency personnel before arriving at our hospital. Complete blood cells and kidney and liver tests were all in normal range. In the emergency department, the patient was treated with oxygen, naloxone, and hypertonic glucose. One dose of activated charcoal (1 g/kg) was administered orally. After intravenous injection of naloxone (4 mg), the lethargy, respiratory depression, and miosis were resolved. The patient was admitted to the intensive care unit and 90 min after admission, the patient redeveloped respiratory distress and lost consciousness. He was intubated and mechanically ventilated due to the suspicious of body packing. Plain abdominal x-ray showed multiple packets throughout the gastrointestinal tract; 81 packets were removed by surgery and three of them were left due to leaking.

After the operation the patients were extubated and then flumazenil 0.4 mg, naloxone 0.05 mg, or nalbuphine 20 mg was given i.v. (randomized and double-blind). In 15 patients blood pressure and heart rate were monitored. In all patients postoperative pain was assessed by the time interval between administration of the antagonist and need for the first analgesic medication. On the 1st postoperative day recall of postoperative events and of pictures shown 5, 30, 60, 120, and 240 min after administration of the antagonist was tested. The patients were interviewed a second time for side effects on day 3-6 after the operation. RESULTS. The three antagonists produced no significant effects on arterial pressure and heart rate. There were no differences between the antagonists in the incidence of postoperative nausea and/or vomiting or postoperative pain. After flumazenil, a significant transient increase in vigilance and better recall of postoperative events was noted within 5 and 30 min after administration of the drug. CONCLUSION. On the basis of the objective clinical findings, there is no reason to prefer either benzodiazepine or opiate antagonists after flunitrazepam and fentanyl. However, postoperative amnesia can be reduced by flumazenil if this is desirable." }, { "id": "pubmed23n0494_18463", "title": "Metformin-associated respiratory alkalosis.", "score": 0.008928571428571428, "content": "We present an 84-year-old man with a history of chronic obstructive pulmonary disease, type 2 diabetes, hypertension, glaucoma, and bladder cancer who presented to the emergency department after the police found him disoriented and confused.

Endogenous benzodiazepine receptor ligands are thought to influence the human hypothalamic-pituitary-adrenal (HPA) axis and naloxone, a known stimulator of adrenocorticotropic hormone (ACTH) release, is thought to act via release of hypothalamic corticotropin-releasing hormone. 2. The aim of the present study was to assess the influence of endogenous benzodiazepine-receptor ligands by administering flumazenil (Ro15-1788), a benzodiazepine antagonist, and measuring ACTH and cortisol release, both basal and during naloxone-stimulation. 3. Nine normal volunteers in a placebo-controlled double-blind design were studied. Flumazenil (0.5 mg, i.v. bolus) was given 2 min before naloxone (125 micrograms/kg bodyweight, i.v. bolus) immunoreactive-adrenocorticotropic hormone (IR-ACTH) and cortisol levels were measured at frequent intervals from 60 min before to 120 min after naloxone injection. 4. Flumazenil had no effect on ACTH and cortisol release when given alone; flumazenil area under the ACTH/time curve (pmol/L.min) = -36.5 +/- 63.5 compared with placebo = -53.5 +/- 31.8, flumazenil area under the cortisol/time curve (nmol/L.min x 10(-3)) = - 2.4 +/- 2.4 compared with placebo -0.56 +/- 1.4. Flumazenil did not change the ACTH and cortisol release achieved with naloxone; naloxone area under the ACTH/time curve (pmol/L.min) = 327.8 +/- 61.7 compared with flumazenil/naloxone = 366.3 +/- 88.1, naloxone area under the cortisol/time curve (nmol/L. min x 10(-3) = 12.2 +/- 3.4 compared with naloxone/flumazenil = 10.5 +/- 2.1. 5.

Child 28 days old, born at term. History of normal pregnancy and delivery. He has been breastfed since birth. He consults because 8 days ago he started vomiting, initially sporadically and since 5 days ago, after all feedings. He is permanently hungry. The vomiting is of "squirting" food content. On palpation, the abdomen is soft and depressible, without visceromegaly. The blood gas analysis showed pH 7.49, bicarbonate 30 mEq/l, pCO2 53 mmHg, base excess +8 mEq/l. Ions: Na 137 mEq/l, K 3.1 mEq/l, Cl 94 mEq/l. Taking into account the most probable diagnosis in the clinical picture described, what is the complementary test of choice to confirm this clinical diagnosis?

Its progressive development as a revealing manifestation of the disease is rare as is its appearance in newborns. Case n. 1.--A 13 month-old girl was admitted because of status epilepticus. She was severely dehydrated (20% weight loss) but had normal diuresis. Investigations showed metabolic alkalosis, hypochloronatremia and hypokalemia. All the manifestations disappeared within 5 days with treatment but three sweat tests were abnormal. Case n. 2.--A 7 month-old girl was admitted because she suffered from progressive loss of weight (10%); she was dehydrated and had metabolic alkalosis plus hypochloronatremia, but her diuresis was normal. Two sweat tests were abnormal. Case n. 3.--A 4.5 month-old boy was admitted because he suffered from severe (12%) weight loss. His diuresis was normal despite dehydration; metabolic alkalosis and hypochloronatremia were found. Two subsequent sweat tests were abnormal. Case n. 4.--A 3 day-old girl was admitted suffering from meconium ileus. Two initial mechanism analysis for protein were abnormal. She had a cardiorespiratory arrest on the 13th day of life, when she had lost 14% of her birth weight; investigations showed metabolic alkalosis, hyponatremia (83 mEq/l), hypochloremia (45 mEq/l); kalemia was 5.9 mEq/l. Peritoneal dialysis was needed to correct hydroelectrolytic changes. A sweat test performed on the 26th day of life was also abnormal. Investigations performed during the periods of dehydration, and repeated later, showed transient functional kidney failure. None of the four patients had any respiratory or gastrointestinal clinical manifestations of cystic fibrosis.

Roentgenograms are the most helpful diagnostic aid. Since the roentgenographic appearance of the normal infant abdomen differs from that of the adult, interpretations should be made with that in mind. In this connection the absence of gas shadows is significant. Although there are dangers in the use of barium in infants, early diagnosis is so important that use of the substance is justifiable if it will help in correct appraisal.

The patient had a family case history of dyslipidemia (Type IV). The pregnancy had been complicated by preeclampsia treated at home with nifedipine tablets (one tablet three times a day) with good results on pressure values; lipidic values were high despite dietary measures taken. The baby at birth weighed 3830 g after physiologic labour and a natural delivery. Acute pancreatitis was diagnosed after observation of epigastralgia with irradiation on the left shoulder, vomiting, symptoms of acute abdomen such as sweating, increased pulse rate, hypotension, abdominal pain on palpation, and absence of peristalsis. An analysis of the blood showed high levels of amylase and hyperglycemia, an increase in XDP, and leucocytosis. Instrumental tests such as pancreatic echography revealed an increase in pancreatic volume, uneven structure of the parenchyma and higher levels of liquid in the peritoneum.

Aldosterone was extremely elevated in the patient 1 when potassium was severely elevated. On the other hand, the patient 2 showed lower aldosterone level after correction of potassium than that on admission. Potassium is regarded as a major secretion factor of aldosterone for patients receiving ACEI. The fact the patient 2 fell into shock during GIT, tells us that we should use steroid simultaneously when we try to correct potassium quickly in severe cases, because acute reduction of potassium may decrease aldosterone. Today, ACEI is a common drug for CHF, so we should pay attentions that ACEI could cause such acute changes. To prevent such acute changes, excessive restriction of water and sodium intake should be avoided. If possible, NSAID and potassium sparing diuretics also should be avoided.

However, when this happens, mortality is high due to delayed diagnosis and/or inadequate treatment. A 42-year-old white man was referred to neurosurgery due to a non-functional pituitary macroadenoma. He underwent a partial resection of the tumor on July 2, 2015. On the day following surgery he presented polyuria with sodium 149 mEq/L, plasma osmolality 301 mOsm/kg, and urine osmolality 293 mOsm/kg. He started nasal desmopressin 0.05 mg/day with good response. He was already on dexamethasone 4 mg and levothyroxine 75 mcg due to hypopituitarism after surgery. On July 9 he became confused. Cerebral computed tomography was performed with no significant changes. His natremia dropped to 128 mEq/L with development of polyuria despite maintenance of desmopressin dose. His hemoglobin and hematocrit rose from 9.1 g/L to 11.6 g/L and 27.5 to 32.5, respectively. His thyroid function was normal and he was on hydrocortisone 30 mg/day. At 12 p.m. 150 mg/hydrocortisone infusion was initiated, but sodium did not increase. Plasma and urine osmolality were 264 mOsm/kg and 679 mOsm/kg, respectively. At 4 p.m. hydrocortisone was increased and hypertonic saline replacement started. Two hours later he was dehydrated with polyuria and vomiting, and natremia of 124 mEq/L. Hyponatremia was very resistant to treatment despite hypertonic saline replacement, hence desmopressin was suspended. The following day, urine spot analysis showed that natriuresis was 63 mEq/L with serum sodium 132 mEq/L. This was interpreted as a cerebral salt wasting syndrome and control was achieved with aggressive hypertonic saline replacements and fludrocortisone 0.1 mg/three times a day. We present a rare case of a patient with diabetes insipidus and cerebral salt wasting syndrome, who was successfully treated. Hyponatremia in a patient with diabetes insipidus may erroneously be interpreted as inadequate diabetes insipidus control or as syndrome of inappropriate antidiuretic hormone secretion, leading to therapeutic errors.

Five patients were F508del homozygotic, 4 were heterozygotic for this mutation, one had another mutation. Sweat tests were positive in all the children. Abdominal distention was observed in 9 patients, vomiting and retention of gastric contents in 5. In 8 children meconium was not passed at all. 2 children passed a small amount of viscid meconium. Before the operation, rectal saline washouts were done in 5 newborns. Five patients were operated on during the first day of life, four on the second day and one on the third day of life. Intra-operatively a simple form of MI was diagnosed in 8 cases, a complicated form in 2 cases. In patients with the simple form of MI, a Bishop-Koop stoma was created after the evacuation of meconium. Two of these children needed a resection of some centimetres of dilated terminal ileum with doubtful viability. In newborns with the complicated form of MI, the treatment was individualized, always with stoma formation. The time of postoperative meconium evacuation through enterostomy ranged from 6 to 15 days. Enteral feeding was started on average on the 9th day postoperatively. The mean hospital stay was 22.9 days. In 8 children the stoma was taken out at the mean age of 19.4 months, in one patient the stoma closed spontaneously. No disturbances in electrolyte balance or excessive fluid loss, nor any body weight deficits connected with the stoma were observed. There were no complications during stoma closure. All the patients are alive. The time of observation ranges from 7 to 146 months (average 95 months). All the patients currently present respiratory symptoms, have pancreatic insufficiency and need pancreatic enzyme supplementation. Seven do not, however, have body weight and height deficits. All the children with weight and height deficits have abnormal liver function tests. During observation two patients had MI equivalent symptoms, which was resolved by conservative treatment. 1. In every case of intra-operative diagnosis of MI, it is necessary to perform genetic testing and sweat tests to confirm or exclude CF. 2. Mechanical intra-operative decompression of the bowel from inspissated meconium with a temporary stoma, which makes the continuation of bowel decompression possible in the postoperative period, is an effective treatment in children with MI. 3. The Bishop-Koop stoma, permitting the passage through the whole gastrointestinal tract, is a safe option. In our material, no complications of this stoma, such as stoma care problems or dyselectrolithemia were observed. 4. The decision of stoma closure in children with MI and CF should be delayed until the moment of introducing a broadened diet and should be undertaken together with a pediatrician who is a specialist in CF therapy. ." }, { "id": "wiki20220301en040_1095", "title": "Metabolic acidosis", "score": 0.008928571428571428, "content": "Diagnostic approach and causes Metabolic Acidosis is defined as a reduced serum pH, and an abnormal serum bicarbonate concentration of <22 mEq/L, below the normal range of 22 to 29 mEq/L.

The hyperosmolar non-ketotic coma without or with only modest ketosis occurring mainly in type II diabetics and the severe ketoacidosis with or without disturbed consciousness occurring mainly in type I diabetics are the two forms of severe metabolic decompensation of diabetes mellitus. 2. Severe hypoglycaemia may be caused by treatment with sulfonylureas and insulin. 3. The most dangerous life threatening adverse effect of biguanides is lactic acidosis. The incidence of ketoacidosis is about 1-5% in type I diabetics with a mortality of 3-9%. Mortality rates of hyperosmolar non-ketotic comas are much higher, approaching 20-40%, and are explained by severe concomitant complications and older age. The most important triggering factors of diabetic coma are infections, insulin dispensing errors and non-compliance. Carefully instructing patients about the risks of loosing appetite and vomiting as early signs of ketoacidosis is essential. Adequate replacement of fluid, electrolyte and water are the most important therapeutical aspects of ketoacidosis and hyperosmolar non-ketotic coma. Early diagnosis and appropriate treatment of infection by antibiotics are important. Complication of therapy (hypokalemia, hypovolemia and rapid full of oncotic pressure) should be avoided by clinical and laboratory monitoring. Treatment of acidosis with bicarbonate has been found more dangerous than useful. Severe hypoglycaemia is the most important and most dangerous side effect of sulfonylurea and insulin. The incidence of severe hypoglycaemia under glibenclamide ist 3-5 fold higher than under treatment with tolbutamide or glibornurid. Glibenclamide should not be recommended anymore. Longterm experience of the therapeutic security of new sulfonylurea derivates like glimepirid is lacking. Blood-glucose-measurements in the afternoon are important for recognizing disposition to sulfonylurea hypoglycaemia, because at this time the blood-glucose-values tend to be lower than in the morning fasting state. Under insulin treatment the following risk factors for severe hypoglycaemia need to be considered: metabolic control in the near normal range, intensified treatment with rapidly decreasing HbA1c-levels, impaired renal function, unawareness o hypoglycaemia. When the renal function is impaired, biguanide treatment is not indicated because of the risk of lactic acidosis.

This adaptation may be associated with severe metabolic acidosis and tends to occur in patients with type I (insulin-dependent) diabetes mellitus. In addition, hypovolemia is an almost invariable finding with marked hypoglycemia and is primarily induced by the associated glucosuria. Ketoacidosis stimulates both the central and peripheral chemoreceptors controlling respiration, resulting in alveolar hyperventilation (Kussmaul's respiration). With the ensuing fall in pCO2 the patient tries to raise the extracellular pH. A fruity odor of acetone on the patient's breath sometimes suggests that ketoacidosis is present. The classical triad of symptoms associated with hyperglycemia are polyuria, polydipsia, and weight loss. Circulatory insufficiency with hypotension is not uncommon due to the marked fluid loss and acidemia. In more severely affected patients, neurologic abnormalities may be seen, including lethargy, seizures or coma. Some patients also have marked vomiting and abdominal pain.

In the setting of diabetic ketoacidosis (DKA), clinicians may note Kussmaul respirations, fatigue, nausea, and vomiting. Funduscopic examination in a patient with DM may show hemorrhages or exudates on the macula. In frank diabetic retinopathy, retinal venules may appear dilated or occluded. The proliferation of new blood vessels is also a concern for ophthalmologists and can hasten retinal hemorrhages and macular edema, ultimately resulting in blindness. While T1DM and T2DM can present similarly, they can be distinguished based on clinical history and examination. T2DM patients are typically overweight/obese and present with signs of insulin resistance, including acanthosis nigricans, which are hyperpigmented, velvety patches on the skin of the neck, axillary, or inguinal folds. Patients with a longer course of hyperglycemia may have blurry vision, frequent yeast infections, numbness, or neuropathic pain. The clinicians must ask the patient bout any recent skin changes in their feet during each visit.

Multiple small oval scaly plaques were noted, extending distally along the ribs to the midline on her back, not crossing the midline, predominantly over the distribution of right T4 dermatome (Figure 1). Peripheral collarette scaling was noted (Figure 2). A few scattered small lesions were also noted in the vicinity of this dermatome. Three isolated small plaques were also present on the trunk, one in the supramammary area and the other two on the abdomen and back, respectively. Palmoplantar and mucosal surfaces were uninvolved.

Biopsy of the skin changes was consistent with GA, showing palisading granulomatous inflammation which surrounded degenerated collagen within the dermis. A routine laboratory check revealed increased levels of glucose (23 mmol/L) and HgbA1C, while lipid and thyroid hormone levels were normal. Fasting blood sugar lever was 17 mmol/L. Therapy with topical corticosteroid (betamethasone cream) for skin lesions was initiated and applied two times daily for 2 weeks. The patient was immediately referred to an endocrinologist and insulin therapy was initiated due to diabetes mellitus. Complete remission of the skin changes was observed on the follow-up visit after 3 months. There are many clinical variants of GA such as localized, generalized, disseminated, subcutaneous, arcuate dermal erythema, and perforating GA (1). The localized form of GA is most common with annular plaques on the distal extremities. In addition to the typical lesions on the dorsal side of both hands, our patient also presented with atypical, circular lesions around her neck. The relationship between GA and systemic diseases such as diabetes mellitus, thyroid disorders, dyslipidemia, and malignancies remains unclear (5). It is also uncertain whether genetic factors influence susceptibility to GA. Familial cases have been documented, but studies investigating the association between the disease and human leukocyte antigen (HLA) genes have yielded inconsistent results (6). Increased frequency of HLA-B35 in patients with the generalized form has been reported in a few studies (7). GA mostly affects children and young adults, mostly women. Many cases of GA resolve spontaneously within 2 years, but relapses occur in many patients. Treatment is divided into localized skin therapies and systemic therapies (1). High potency topical corticosteroids along with intralesional corticosteroids are the most common localized treatments (8). Systemic therapy includes corticosteroids, chloroquine, dapsone, and isotretinoin (1,9). Cryotherapy and UV-therapy can also be used, although with limited efficacy (10). GA is a common idiopathic disorder of the dermis and subcutaneous tissue that can be associated with a variety of underlying conditions such as diabetes mellitus. The relationship between GA and diabetes mellitus is still unknown. Since skin lesions preceded the diagnosis of DM in our patient and complete remission of skin changes occurred with induction of insulin therapy, it is important to perform routine laboratory test in every patient." }, { "id": "pubmed23n1060_6600", "title": "Acute Generalized Exanthematous Pustulosis After COVID-19 Infection: A Case Report From Saudi Arabia.", "score": 0.009900990099009901, "content": "There is a dearth of robust evidence regarding coronavirus disease 2019 (COVID-19)-related coetaneous manifestations, complications and adverse treatment events.

A 30-year-old woman presented to our Department with persistent, asymptomatic face edema and erythema lasting for 18 months. She was previously treated for rosacea with doxycycline (100 mg/day for four months) without improvement. Dermatological examination revealed erythematous, nonpitting, solid edema located on the mid-forehead, nose, and cheeks with sparse erythematous papules and pustules on the entire face including the chin and comedones, papules, and pustules on the back (Figure 1 and Figure 2). She was otherwise healthy and was not taking any medication. Laboratory tests with immunological tests and Quantiferon test together with MRI of the orbits, chest X-ray, chest high-resolution computed tomography, cranial X-ray, and abdominal ultrasound were all within normal limits. Histopathology revealed dermal edema, perivascular and peri-adnexal lymphohistiocytic infiltrate, and sebaceous gland hyperplasia. Based on the typical clinical picture, histopathological findings, and the exclusion of several differentials the diagnosis of MD was established. The patient was treated with oral isotretinoin (20 mg/day for eight months) without regression of solid edema and erythema on the face but with complete regression of acne on the trunk. She was started on oral corticosteroids (prednisolone, 20 mg/day for two months followed by reduction of the dose over three months), again with only slight short transient improvement and rapid relapse of facial erythema and edema. The patient refused any other suggested treatment. We treated our patient for a total 2 years and followed up for 5 years. The pathogenesis of MD is still unknown. It is considered a clinical variety or a complication of rosacea or acne which does not tend to regress spontaneously. It is believed that chronic inflammation in patients with MD is due to acne or rosacea causing structural damage to blood and lymph vessels (1,3,4). However, cases of MD without previous history of rosacea and acne have been reported supporting the distinct disease theory (3,4). Edema and erythema are localized on the upper half of the face affecting the forehead, glabella, eyelids, nose, and cheeks. Although the symptoms may come and go, MD usually does not improve without treatment (5). Several therapeutic options have been reported, although there is no established standard treatment for MD. Reported therapy includes short-term oral isotretinoin (0.5 mg/kg/day), long-term oral isotretinoin (40-80 mg/day, 10-24 months), long-term doxycycline, combination of systemic corticosteroids and antibiotic (prednisolone 20 mg/day for 2 weeks and doxycycline 200 mg/day for 12 weeks), slow-releasing doxycycline monohydrate (40 mg/day for 6 months), long-term minocycline (50 mg/day for 4 months), and a combination of both oral retinoid and ketotifen (isotretinoin 0.7 mg/kg/day for 4 months, ketotifen 2 mg/day for 4 months) (1,2,6,8). The disease is frequently recalcitrant to therapy, and only several cases of successfully treated patients with MD have been reported (1,2,4, 6-8).

Cutaneous adverse reactions are usually maculopapular exanthemas, although hypersensitivity syndrome, acute generalized exanthematous pustulosis, and Stevens-Johnson syndrome have also been reported (1). We report the case of a patient with a maculopapular rash triggered by clindamycin who developed cutaneous lesions on striae distensae (SD). A 47-year-old woman was referred to our clinic for pruritic cutaneous lesions which had started 6 days earlier. Her past clinical history included hypertension, hypothyroidism, hyperuricemia, cholecystectomy, caesarean section, and endometriosis-related abdominal surgery, and she was taking levothyroxine, allopurinol, imidapril, and omeprazole. The skin rash first developed on her neck and back on the 3rd day of clindamycin oral treatment (300 mg every 6 hours), which was prescribed as antibiotic prophylaxis for a tooth implant. General malaise (but not fever) was also reported. Physical examination revealed an erythematous maculopapular eruption symmetrically distributed on the neck, abdomen, and back (Figure 1, A), with isolated lesions involving the proximal upper and lower limbs (Figure 1, B). There was a striking vertical distribution of skin lesions along the SD on the lateral sides of the abdomen (Figure 1, C). No mucosal involvement was found, and laboratory studies showed no abnormalities. Clindamycin withdrawal was followed by prescription of a course of oral deflazacort, starting at 30 mg daily and tapering down during a 9-day period. On the 5th day of treatment, the rash had almost cleared with minimal desquamation (Figure 1, D). Eight weeks after clearance of the skin rash, informed consent was obtained in order to perform an allergological evaluation of clindamycin, including prick and intradermal (ID) tests on the forearm and patch tests on the upper back (2). For patch testing, powder of the commercial capsules (Dalacin®) was diluted in petrolatum (pet.) and water (aq.), resulting in a final 1% clindamycin dilution. Parenteral clindamycin preparations were used in therapeutic concentrations for prick tests (150 mg/mL) and dilutions in saline of 1/100 and 1/10 for the ID test. Other authors have reported that these concentrations do not seem to irritate the skin (3-6). Prick and ID tests were assessed after 20 min and 24 hours, respectively. Patch tests were removed after the 2nd day, and late reactions were evaluated on day 2 and day 4. Prick and ID test results after 20 min were negative. Late results of ID tests with clindamycin (1.5 and 15 mg/mL) were positive: erythematous infiltrated papules about 7×7 mm and 18×15 mm were observed at 24 hours and lasted until the 8th day. Patch tests with clindamycin 1% in pet. and 1% in aq. were also positive (+ on day 2 and day 4). Positive late skin tests suggested delayed-type non-IgE-mediated allergic clindamycin hypersensitivity. Oral challenge tests are considered to be the gold standard to establish or exclude drug hypersensitivity. Due to the positive result of late skin test to clindamycin, oral challenge was not performed in our patient (3,5). The Koebner isomorphic phenomenon has been described in cutaneous reactions induced by drugs, such as antibiotics and chemotherapy. Chronic pressure on the skin is probably involved in the onset of skin lesions in hand-foot eruptions induced by tyrosine kinase inhibitors (sorafenib and sutinib). Solar exposure and cutaneous trauma also seem to play a role in the location of papulopustular eruptions caused by endothelial growth factor receptor inhibitors (erlotinib) (7). More frequent involvement in traumatized skin and surgical scars has been reported in the context of linear IgA bullous dermatosis and leukocytoclastic vasculitis triggered by vancomycin and cefuroxime (8). SD are produced by non-penetrating physical trauma, similar to friction or pressure. Different dermatoses can develop along SD skin lesions (like plaque psoriasis, pustular psoriasis, lichen planus, vitiligo, discoid lupus erythematosus, lupus vasculitis, urticarial vasculitis, or chronic graft-versus-host disease) (9). Bevacizumab, etretinate, and corticosteroid-induced ulcers, hyperpigmentation caused by bleomycin, and urticariform lesions triggered by diclofenac are examples of different type of drug-induced abnormalities involving SD (10). In summary, we identified clindamycin as the cause of the cutaneous reactions that occurred in our patient on the basis of the results of the skin tests and clinical history. Our findings confirmed a delayed-type hypersensitivity reaction, possibly involving a T-cell-mediated immunologic mechanism. Intradermal and patch tests were found to be useful in order to confirm the diagnosis (4,5). We did not find reports in the literature of drug-induced cutaneous eruptions along the SD as a manifestation of a Koebner phenomenon. Clinical underreporting of this phenomenon could explain the scarce literature on this cutaneous adverse reaction." }, { "id": "pubmed23n0747_8257", "title": "A 12-year-old boy with foot lesions.", "score": 0.009174311926605505, "content": "CME EDUCATIONAL OBJECTIVES: 1.Identify the clinical presentation of granuloma annulare.2.Describe the differential diagnosis for granuloma annulare.3.Discuss the appropriate management for granuloma annulare.

There are many dermatologic conditions which a primary care provider (PCP) should be able to recognize and manage. One such condition is granuloma annulare (GA), which commonly presents as smooth, annular plaques on the trunk and/or extremities. Rashes like GA rarely present as unique variants and may be difficult for PCPs to determine from patient history and physical exam alone. Patch granuloma annulare (patch GA) is an example that may clinically mimic a cutaneous lymphoma known as mycosis fungoides (MF). PCPs should ideally be able to recognize the utility of performing a skin biopsy and/or referring the patient to a dermatologist when history and physical exam alone are insufficient. The histologic findings of skin biopsies often become essential in establishing a proper diagnosis and guiding patient management in unique dermatologic variants. The patient in this clinical practice report is a Caucasian female in her late 60s who presented to a dermatology clinic with a two-year history of a worsening widespread eruption on her trunk and extremities. She had been evaluated previously by her PCP about 4 months prior and, without obtaining skin biopsies, treated her with a medium potency topical corticosteroid cream. The eruption had spread over her hips, buttocks, back, thighs, wrists, and elbows. Multiple skin biopsies of affected sites were taken by the second author and revealed findings consistent with patch GA. The patient was started on topical betamethasone dipropionate 0.05% ointment twice daily and noted marked improvement of her symptoms. Although GA is a benign condition of the skin that may be readily detected by PCPs, skin biopsies may be necessary to establish a proper diagnosis when this condition presents as a unique variant (e.g., patch GA). Therapy for patch GA often begins with a trial of high-potency topical steroid therapy in combination with ultraviolet light exposure, depending on disease severity and patient preference. Early evaluation with a skin biopsy by her PCP or an earlier referral to a dermatologist to have skin biopsies performed likely would have helped establish a prompter diagnosis and treatment plan for this patient." }, { "id": "pubmed23n1097_14269", "title": "Chronic unilateral anterior scleritis, think about a herpetic origin: A case report.", "score": 0.009009009009009009, "content": "Scleritis is a very heterogeneous group of diseases responsible for ocular inflammation of varying severity, the evolution and prognosis of which depend on the etiology but also on the appropriate treatment.

She began to develop these lesions at the age of 9 years, with healing of the lesions resulting in scar formation. A biopsy was performed at the age of 16 years, but the patient was unsure of the results. Since then, she had not had any treatment or biopsies, and stated that she had not suffered from any health problems during the intervening period. She was most concerned about the tumors on her heels and soles, which caused difficulty with ambulation. The family history was negative for skin diseases, including melanoma, nonmelanoma skin cancer, psoriasis, and eczema, and positive for Type II diabetes mellitus. A relative reported that the patient's grandfather had similar lesions, but the patient's parents and siblings were healthy. She was married and had one child, a 9-year-old daughter. Her child had no skin lesions. The patient's only medication was Ortho-Tricyclene birth control pills. She had no known drug allergies. Physical examination revealed the presence of multiple lesions on her body (Fig. 1). Her left superior helix contained a well-demarcated, dome-shaped nodule with a rolled, mildly erythematous border with a central hyperkeratotic plug. A similar lesion was present in the scaphoid fossa of the left ear and smaller lesions were scattered on her face. Numerous lesions were present on the arms and legs bilaterally, with the majority of lesions being located on the anterior lower legs. There were also lesions present on the palms and soles. The lesions ranged in size from 5 mm to 3 cm, the largest being a verrucous exophytic nodule on the anterior aspect of her left leg. Overall, there appeared to be two distinct types of lesion. One type appeared round, oval, and symmetric with a central keratotic plug, similar to that on the ear. The other type was larger, more exophytic, and verrucous, including the lesions on the volar surfaces. Also present were numerous, irregularly shaped atrophic scars where previous lesions had healed spontaneously. There were no oral lesions or lesions on her fingernails or toenails, and her teeth and hair were normal. A biopsy was obtained from an early lesion on the right dorsal forearm. Histology revealed an exo-/endophytic growth having a central crater containing keratinous material (Fig. 2). The crater was surrounded by markedly hyperplastic squamous epithelium with large squamous epithelial cells having abundant glassy cytoplasm. Some cells were dyskeratotic. Within the dermis was a dense, chiefly mononuclear inflammatory infiltrate. A buttress of epidermis surrounded the crater. The clinical and pathologic data were consistent with keratoacanthomas. Initial laboratory screenings revealed elevated triglycerides and total cholesterol, 537 mg/dL (normal, &lt; 150 mg/dL) and 225 mg/dL (normal, &lt; 200 mg/dL), respectively, with all other laboratory results within normal limits. In anticipation of starting oral retinoid therapy for her multiple keratoacanthomas, she was referred to her primary care physician for control of hyperlipidemia. After her lipids had been controlled, she was placed on isotretinoin (Accutane) 40 mg/day. There was some interval improvement with regression of some lesions leaving atrophic scars. She was also started on topical application of tazarotene (Tazorac) for all nonresolving lesions. Possible side-effects from the isotretinoin occurred, including dry mouth and eyes. After 8 months of isotretinoin, the patient was switched to acitretin (Soriatane) 25 mg to determine whether it might have a more beneficial effect on the resistant lesions. Many of the larger lesions regressed leaving atrophic scars. The dose of acitretin was subsequently increased to 35 mg because the lesions on her heel and the ball of her foot persisted. Almost all of the lesions resolved, except those on her feet, which are slowly regressing. Currently, the patient is on a regimen of acitretin 25 mg once a day with tazarotene 0.1% gel applied directly to the few residual keratoacanthomas on her feet, which are slowly improving." }, { "id": "pubmed23n0691_10650", "title": "Painful ulcers in a 5-year-old girl.", "score": 0.008928571428571428, "content": "A 5-year-old girl was admitted to our clinic with several painful ulcers spreading from the right elbow to the armpit.

Simultaneous involvement of the oral mucosa is extremely rare, but it may be the only affected area (2). A 55-year-old woman was referred to the Department of Oral Medicine, School of Dental Medicine University of Zagreb due to whitish lesions on the right ventrolateral part of the tongue and buccal mucosa with desquamative gingivitis (Figure 1, a-c). The lesions were asymptomatic but indurated on palpation. Histology was conclusive for oral lichen sclerosus (OLS). The lesions on gingiva were successfully treated with betamethasone ointment, three times a day for two weeks. One year earlier, she had been referred to the Department of Dermatology and Venereology with progressive pruritus and dyspareunia, white patches, obliteration of the labia minora, and stenosis of the introitus (Figure 2). Histology was conclusive for vulvar LS (Figure 3, a and b). She was successfully treated for 5 months with clobetasol propionate 0.05% ointment. The patient was taking levothyroxine to treat hypothyroidism associated with Hashimoto's thyroiditis and was otherwise healthy. Oral LS is clinically characterized by the appearance of white macules, papules, or plaques mostly appearing on labial mucosa but also on buccal, palate mucosa and on the lower lip (2,3). On the genitals, it typically manifests as atrophic white plaques, which may be accompanied by purpura or fissuring (1). While vulvar LS is often associated with pruritus, dyspareunia, and dysuria, OLS is often asymptomatic, although pain, soreness, pruritus, and tightness when opening the mouth can be present (1,2). Oral manifestations of LS, as well as association of anogenital and oral LS, are rarely reported in the literature (4-6). Tomo et al. searched the Medline database for papers reporting oral LS cases with histological diagnosis confirmation from 1957 to 2016 and found only 34 cases of oral LS with histopathologic confirmation of the diagnosis (4). Kakko et al. reported 39 histologically proven cases of OLS (2). Attilli et al. (5) reviewed the clinical and histologic features of 72 cases of LS with oral/genital involvement. They reported that LS was diagnosed with exclusive genital lesions in 45, exclusive lip involvement in 20, and orogenital involvement in only 7 cases (5). Some believe that many cases of clinically diagnosed lichen planus may actually be LS and that isolated oral mucosal LS may not be as rare as is generally thought (2). While vulvar LS can occur at any age with increasing incidence with age, the median age of patients with OLS was 34 years and most of the patients were female (1,2,5). Due to the small number of patients in the literature, treatment recommendations for OLS are not available. In case of symptomatic oral lesions, topical or intralesional corticosteroids are considered to be the first-line treatment (2). First-line treatment for anogenital LS is a potent to very potent topical corticosteroid ointment, and second-line therapies include topical calcineurin inhibitors 1% pimecrolimus and 0.1% and 0.03% tacrolimus (1). For treatment-resistant genital LS, oral retinoids, methotrexate, and possibly local steroid injections for single lesions are mainly applicable for women (1). There is limited evidence for systemic treatments for both conditions. If it is not treated, genital LS is associated with a greater degree of scarring and an elevated risk of progression to squamous cell cancer; however, malignant transformation of OLS has not been reported (1-6). Due to the very rare presentation in the oral cavity, it is important to notice these lesions during a dental exam." } ] } } }

The first patient, an 18-year-old woman who had expanded her athletic activities extensively, had developed pain at the inner side of the distal third portion of the left lower leg. She showed over-pronation of the ankle during running. A 3-phase bone scintigram revealed diffuse uptake of the tracer covering a large portion of the medial tibia margin. Based on this evidence, a diagnosis of periostalgia was made. She recovered after a period of relative calf massages and used insoles. The second patient was a 28-year-old male endurance runner who developed pain at the medial shin after intensifying his training regimen. The periods without pain during running became increasingly shorter, and the medial side of the lower leg became sore and tense. Intracompartmental pressure measurements indicated exercise-related posterior deep compartment syndrome of the calf. The patient recovered after fasciotomy. In athletes, exercise-related symptoms of the medial side of the lower leg can be usually attributed to the tibial periosteum or tendons of the deep calfmusculature, tibial stress reaction or fracture, or a compartment syndrome of the deep calf. Surgery is indicated for chronic compartment syndrome, but conservative therapy provides favourable outcomes in the other types of disorders. The optimal conservative therapeutic approach is unknown, but it is advisable to temporary reduce symptom-provoking athletic activity and modify any risk factors present. Ankle over-pronation during running is considered a very relevant intrinsic risk factor." }, { "id": "pubmed23n0489_6509", "title": "[MR-Imaging of lower leg muscle perfusion].", "score": 0.01747674767476748, "content": "This article describes the potential of dynamic contrast- enhanced magnetic resonance tomography (DCE-MRT) for the visualization and quantification of blood flow of lower leg muscles at rest and after individually adjusted muscular exercise. Five cases were chosen to exemplify the qualitative and semi-quantitative blood flow evaluation in the lower leg muscles. The crural muscle state was determined with an isometric maximal strength measurement from a female patient with peripheral arterial occlusive disease (pAVK), a male patient with coronary heart disease (KHK) without clinical signs of a pAVK, a volunteer with sufficient physical activity in accordance with the Freiburg Questionnaire of Physical Activity and two professional athletes. After calibration of the plantarflexion ergometer MR-PEDALO (Figures 2a and 2b) for the execution of auxotonic muscle work a 1- minute alternating foot extension and flexion exercise on MRPEDALO was performed in the MR machine. Instead of the lower leg splint shown in Figures 2a and 2b the MR coil fits exactly in MR-PEDALO used for DCE-MRT. Mechanical work performed during the 1-minute exercise ranged from 52 watt seconds (Ws) to 244 Ws (0.65 W to 4.07 W), indicating similar interindividual work loads in relation to the individual maximum isometric strength. DCE-MRT was performed at rest and immediately after auxotonic exercise test (T1w 2DFLASH- GE sequence with TR/TE/alpha: 100 ms/6 ms/70 degrees; field of view: 400; matrix: 81 x 256; slice thickness: 10 mm; acquisitions: 73 at 8.3 s each; total examination time: 9.24 min; bolus application of Magnevist, Schering, 0.02 ml/kg kg, 20 ml bolus NaCl, flow 2 ml/s, 22G cannula in a cubital vein). Signal intensity (SI) curves were analyzed with DynaVision (MeVis gGmbH, Bremen, Germany). Measuring peripheral blood flow needs appropriate muscular stress tests. The SI-curves of the region of interest (ROI) representing the peroneus, tibialis anterior and gastrocnemius muscle run almost parallel at rest. Workloads between 52 Ws and 244 Ws (0.65 W and 4.07 W), similar in relation to the individual maximum isometric strength, induce distinctive changes of the upslope, wash-in, peak and washout of SI-curves preferably for the peroneus muscle and less predominant also for the tibialis anterior muscle and gastrocnemius muscle respectively. The first case, a 55-year-old female patient with peripheral arterial occlusive disease (pAVK) stage Fontaine IIb before (Figure 3a) and after (Figure 3b) percutaneous transluminal angioplasty (PTA) of a right femoral artery stenosis shows after interventional treatment a rapid post-exercise SI-increase in the peroneus muscle. The steeper SI-curve indicates a better contrast medium inflow due to an improved perfusion. The second case, a 65-year-old man suffering from coronary heart disease without clinical signs of pAVK (Figure 4) exercised with a workload of 92 Ws. After stress test the ROI for the peroneus muscle shows a clear intensity increase. After exercise the SI-curve for the tibialis anterior muscle shows a similar, but less predominant change while the shape of the SI-curve of the gastrocnemius muscle remains mainly identical. A 23-year-old male person with average physical activity (Figure 5) performed DCE-MRT of the left lower leg after stress test with 172 Ws demonstrating a rapid signal increase in the peroneus muscle while the synergistic tibialis anterior muscle and antagonistic gastrocnemius muscle show a comparatively slow contrast-medium wash-in. A 26-year-old male athlete (Figure 6) exercised with 196 Ws showing a rapid contrast medium inflow in the peroneus muscle and initially also in the synergistic tibialis anterior muscle. A contrast-medium wash-out appears in both muscles, while the shape of the gastrocnemius muscle SI-curve remains substantially unchanged. A 26-year-old female athlete (Figure 7) exercised with 244 Ws. Post exercise SI-curves show a distinctive and rapid increase of contrast medium wash-in with a sharp peak particularly in the peroneus muscle and similarly in the tibialis anterior and gastrocnemius muscle. After exercise all SI-curves show a wash-out phase. SI-curves show relative increase in correlation with Time-to-Peak (TTP) decrease and Mean-Intensity to Time Ratio (MITR) increase indicating blood flow reserve mobilization after exercise. Individual muscle state seems to be linked to muscle recruitment and muscle coordination reflected by post-exercise SI-curves. The gastrocnemius muscle shows comparatively low SI-curve changes after muscular load test. Further methodological standardization and optimization of the stress test is mandatory to assure intra- and interindividual comparisons. Due to direct visualization and quantitative evaluation of the peripheral microcirculation DCE-MRT has a diagnostic potential for monitoring therapeutic response in peripheral circulation disorders and sports medicine." }, { "id": "pubmed23n0909_23174", "title": "Selective Fasciotomy for Chronic Exertional Compartment Syndrome Detected With Exercise Magnetic Resonance Imaging.", "score": 0.015420023014959722, "content": "Chronic exertional compartment syndrome that is refractory to conservative management should be treated with surgical fasciotomy. However, owing to the limitations of intracompartmental needle manometry in reaching a definite diagnosis, the appropriate timing for fasciotomy and on which compartment remain unclear.

The pain was located at the lateral aspect of the calf, from the mid-calf level to the ankle. At another hospital, nonenhanced magnetic resonance imaging had been performed, which showed no considerable abnormality. The authors used exercise magnetic resonance imaging to diagnose chronic exertional compartment syndrome. They performed selective fasciotomy on the compartment that showed a high signal intensity. As a military cadet, the patient was required to jog for more than an hour per day and perform strenuous muscle exercises. He reported that he did not have calf pain or discomfort during such activities 13 months postoperatively. The authors obtained a follow-up exercise magnetic resonance image. Compared with the preoperative magnetic resonance image, the follow-up exercise magnetic resonance image did not show high signal intensity at the lateral compartment.

In the previous four months, several anti-inflammatory drugs and painkillers associated with physiotherapy treatments gave no significant improvement in pain and self-care. After an ultrasound (US) and an 18-fluorodeoxyglucose positron emission tomography associated with total body computed tomography (18-FDG PET/CT) examination, PMR was diagnosed and he started therapy with 17.5 mg prednisone, obtaining a fast improvement in pain and self-care. After 10 months of tapering, he stopped prednisone without relapse. During a 3-year follow-up, no alternative diagnosis was done. When a patient complains of chronic bilateral shoulder and hip girdle pain associated with normal inflammatory indices, it is reasonable to think in the first instance that this person is not suffering from PMR.

The aim of the present case report is to indicate that fluorine-18-fluorodeoxy-glucose positron emission tomography/computerized tomography((18)F-FDG PET/CT) scan can be used for the evaluation of pain at the site of arthroplasty with a semi quantitative measurement. An 84 years old male patient, with a history of papillary thyroid cancer was referred to our Nuclear Medicine Department for an (18)F-FDG PET/CT scan for evaluation of his metastatic disease. He reported right hip prosthesis thirty years ago and now suffered from significant pain in the right hip joint which on a scale from 1 to 10 could be rated as grade 8. White blood cell count, sedimentation rate and C-reactive protein were within normal limits. Four years ago he also had severe pain on the right leg that could be rated as grade 8, and underwent an (18)F-FDG PET/CT scan that showed a maximum standardized uptake value (SUV(max)) of 9.8. A year later, at a follow up (18)F-FDG PET/CT scan and under a similar severe pain, SUV(max) was 10. The patient had a hip prosthesis in the left leg 3 years ago, for which he reported pain that could be rated as grade 3 and the SUV(max) was then 3.7. The degree of (18)F-FDG uptake is related to cellular metabolic rate and to the number of glucose transporters. In inflammation, the activated inflammatory cells demonstrate increased expression of glucose transporters and the affinity of glucose transporters for deoxyglucose is increased by various cytokines and growth factors. Furthermore, when the mononuclear cells and the granulocytes are activated by certain infectious humoral stimuli, they use large amounts of glucose by the hexose monophosphate shunt and the rate of oxygen uptake is intensely increased, during the so called \"respiratory burst\". In the present case, it was interesting to note that the degree of (18)F-FDG uptake at the sites of loosening hip arthroplasty was related to the severity of pain. Signs of infection or inflammation although not obvious in our case, could not be excluded because sensitivity, specificity and accuracy of PET for detecting infection associated with hip prostheses has been reported to be, 90%, 89.3% and 89.5%, respectively and sensitivity and specificity for detecting periprosthetic inflammation 100% and 45.5%,respectively. In another study using as a criterion for periprosthetic infection the increased (18)F-FDG activity at the bone-prosthesis interface of the femoral component, sensitivity, specificity, positive and negative predictive values for the (18)F-FDG PET study where 85%, 93%, 80% and 95%, respectively. Inflammation, often intense, may be present in aseptic loosening and characterized by increased periprosthetic (18)F-FDG uptake. In conclusion, in our case the degree of (18)F-FDG uptake in a loosening hip arthroplasty was related to the severity of pain although inflammation or infection could also play some role. Further studies are required to prove this suggestion." }, { "id": "pubmed23n0245_9231", "title": "Exercise hyperemia for the study of peripheral circulation.", "score": 0.00980392156862745, "content": "Blood flow in the calf was measured during postexercise hyperemia in normal subjects and in PAD patients by means of a foot ergometer that gives direct reading of the work performed. In normals, first and peak flow increased with the rise of work load up to 100 KGM. The duration of hyperemia increased with a work load of 30 to 200 KGM. In PAD patients, first flow did not coincide with peak flow. Peak flow was lower and delayed, and the duration of hyperemia was more prolonged than in normal subjects. In patients with intermittent claudication, first flow, peak flow, and work load were higher than in patients with rest pain or impending gangrene. Exercise hyperemia appears as a useful test for screening normal limbs from those with arterial obstruction. Since in PAD patients exercise is interrupted when muscular pain appears, it is evident that the earlier the arrest of work and the appearance of pain, the greater is the involvement in the arterial tree of the leg.

CRPS from a mild herniated intervertebral disc (HIVD) without surgical intervention is even rarer than CRPS after an operation for disc disease.A 22-year-old man was transferred to a pain clinic. He had continuously complained about back and right leg pain. He presented with a skin color change in the right lower leg, intermittent resting tremor, stiffness, and swelling in the right leg. He complained of a pulling sensation and numbness in his right buttock, posterior thigh, lateral calf, and ankle. This symptom was in accordance with L4/5 radiculopathy. Magnetic resonance imaging (MRI) also showed L4/5 HIVD that was central to the bilateral subarticular protrusion.He was diagnosed as having CRPS, which fits the revised International Association for the Study of Pain (IASP) criteria. He fulfilled 4 symptom categories (allodynia, temperature asymmetry and skin color change, sweating changes, decreased range of motion and motor dysfunction) and 3 of 4 sign categories (allodynia, temperature asymmetry and skin color changes, decreased range of motion and motor dysfunction). The bone scan and thermography also revealed CRPS.For the past 2 months, we have performed intensive treatments. But, he never became pain-free and walking for 5 minutes led to persistent leg pain. We decided to perform percutaneous nucleoplasty, which can directly decompress a HIVD. On the next day, he achieved dramatic symptom relief. The visual analog scale (VAS) score improved to 3, compared to the VAS score of 9 at the first visit. The skin color change, allodynia, and tremor in the right leg disappeared, and the temperature asymmetry normalized. Motor weakness of the right leg also recovered.We report an unusual case of CRPS that was caused by L4/5 HIVD without a history of trauma or surgery. It has a clear causal relationship between HIVD and CRPS and definitively fits in the newly revised IASP criteria. In conclusion, mild HIVD can cause CRPS without any trauma.

The diagnosis of CECS is primarily made on careful history and physical exam. The gold standard test to confirm the diagnosis of CECS is invasive intra-compartmental pressure measurements. Sensory nerve function is often diminished during symptomatic periods of CECS. Sensory nerve function can be documented with the use of non-painful, non-invasive neurosensory testing. Non-painful neurosensory testing of the myelinated large sensory nerve fibers of the lower extremity were obtained with the Pressure Specified Sensory Device in a 25 year old male with history and invasive compartment pressures consistent with CECS both before and after running on a tread mill. After the patient's first operation to release the deep distal posterior compartment, the patient failed to improve. Repeat sensory testing revealed continued change in his function with exercise. He was returned to the operating room where a repeat procedure revealed that the deep posterior compartment was not completely released due to an unusual anatomic variant, and therefore complete release was accomplished. The patient's symptoms numbness in the plantar foot and pain in the distal calf improved after this procedure and his repeat sensory testing performed before and after running on the treadmill documented this improvement. This case report illustrates the principal that non-invasive neurosensory testing can detect reversible changes in sensory nerve function after a provocative test and may be a helpful non-invasive technique to managing difficult cases of persistent lower extremity symptoms after failed decompressive fasciotomies for CECS.

The purpose of this study was to investigate the high-energy metabolism in the calf muscle of patients with PAD with isolated aorto-iliac stenoses during incremental plantar flexion exercise. Using a 1.5 T whole-body magnetic resonance (MR) scanner, 12 patients with PAD with uni- or bilateral aorto-iliac atherosclerotic lesions and 10 healthy male controls underwent serial phosphor-31 MR spectroscopy during incremental exercise at 2, 3, 4, and 5 W. The phosphocreatine (PCr) time constants were calculated for each increment and recovery using a monoexponential model. In the patient group, the run-off resistance was determined on MR angiograms. In both the patients and the controls, the ankle brachial pressure index was measured. The diseased legs exhibited significantly increased PCr time constants during the second and the third workload increment at 3 and 4 W, but not during the first increment at 2 W and recovery compared with normal controls. Only 3 diseased legs succeeded the last increment at 5 W. We detected significant correlations between the ankle brachial pressure index scores and the PCr time constants when including both the diseased and the control legs.

One year after the initial deep vein thrombosis (DVT) the patient returned to contact sport, however he continued to have intermittent symptoms of right lower leg pain and right knee effusion.Athletes can develop vascular injuries in a variety of contact and non-contact sports. Trauma is one of the most common causes of lower extremity deep vein thrombosis (DVT), however athletic injuries involving lower extremity traumatic DVT are seldom reported. This diagnosis and the associated risk factors must be considered during the initial physical examination. The primary method of radiological diagnosis of lower extremity DVT is a complete bilateral duplex sonography, which can be augmented by other methods such as evidence-based risk factor analysis. Antithrombotic medication is the current standard of treatment for DVT. Acute thrombolytic treatment has demonstrated an improved therapeutic efficacy, and a decrease in post-DVT symptoms.There is a lack of scientific literature concerning the return to sport protocol following a DVT event. Athletic individuals who desire to return to sport after a DVT need to be fully informed about their treatment and risk of reoccurrence, so that appropriate decisions can be made." }, { "id": "pubmed23n0108_12287", "title": "[Regional blood flow and oxygen consumption in the leg muscles of normal subjects and in those with arterial insufficiency.

Furthermore, magnetic resonance angiography was performed, and the ankle-brachial pressure index was determined in the patient group. The runoff resistance (ROR) was separately assessed in each patient's leg. The symptomatic legs exhibited significantly increased phosphocreatine (PCr) time constants during the first three workload increments (2-4 W) and the recovery phase compared with the asymptomatic legs and the normal controls. Only two symptomatic legs reached the last increment at 5 W. Compared with the normal controls, the asymptomatic legs showed significantly increased PCr time constants only at 5 W. In the patient group, we detected significant correlations between the PCr time constants and the ROR, as well as the ankle-brachial pressure index. Moreover, the symptomatic legs presented significantly lower PCr levels and pH values at the end of exercise compared with the asymptomatic and control legs. Our study shows that muscle function in PAD patients can be objectively quantified with the help of 31P magnetic resonance spectroscopy and correlates significantly with hemodynamic parameters such as ROR and ankle-brachial pressure index.

Pain pressure threshold testing of the Achilles tendon was performed, followed by a single session of noxious electric stimulation to bilateral Achilles tendons, and the subject was instructed to continue with eccentric gastroc-soleus complex strengthening as previously performed. Pain pressure threshold testing was performed to the mid-portion of the posterior Achilles tendon. The left Achilles tendon mean was 10.50kg and right Achilles tendon was 8.33kg prior to the noxious stimulation intervention. Twenty-four hours after the noxious stimulation treatment, improvements in mean pain threshold testing were found for both the left (16.31kg) and right (12.36kg) Achilles tendons. At one month after the physical therapy noxious stimulation session, the subject was able to progress his workouts to include sprints and interval training. His LEFS improved to 76/80 and his VISA-A improved to 96%. The case illustrates the successful pain reduction and return to progressive sports activity in a runner with chronic Achilles tendinopathy. The utilization of noxious electric stimulation may have altered the pain perception of the nervous system as evidenced by the improvement in pain pressure threshold testing.

Tomograms were recorded at the greatest diameter of legs, at rest and ten minutes after a treadmill walk test leading to the development of ischemic pain in the affected leg. In 5 patients, F and E were correlated with the results of occlusive venous strain gauge plethysmography and with the measurements of blood gases in one brachial artery and in the femoral vein of the affected limb. Blood flow values measured at rest and after exercise by PET were poorly correlated with the plethysmographic findings. This may be because PET does not interfere with flow as venous occlusion plethysmography does in low peripheral pressure conditions. The results show that F, R, and E were not significantly different in normal and pathologic legs at rest. The values of F and R were significantly higher in pathologic than in normal lower limbs, ten minutes after exercise, whereas E was not significantly altered by exercise at any side.

The patient experienced numbness, tingling, and cramping along the lateral and posterior portions of her legs during basketball practice, and her symptoms had gradually worsened over the past eight months. She obtained minimal relief with conservative treatments such as stretching and rest. X-rays and MRI of the lower limbs were obtained six months after symptoms began and were unremarkable. Further evaluation included compartment pressure testing taken before and after exercise. The patient demonstrated diagnostic pressures indicative of compartment syndrome in two compartments bilaterally. The patient was subsequently diagnosed with exertional compartment syndrome. Exertional compartment syndrome is a cause of muscle pain that occurs due to increased tissue pressure within the confinement of the closed fascial space during exercise. Patients are often misdiagnosed or there is a significant delay in the correct diagnosis. The gold standard for diagnosis is measurement of intracompartmental pressures with the Stryker catheter. Clinicians should consider exertional compartment syndrome in active patients who present with generalized muscle pain or sensation deficits that worsen with activity and are relieved with rest. Surgical intervention is a reasonable intervention and the only definitive option for an athlete with chronic exertional compartment syndrome who wants to continue high-level competition. Endoscopic fasciotomies are the new preferred techniques compared to more invasive open surgeries, which require a full incision. Endoscopic fasciotomy has a quicker healing time and has been shown to be as effective at relieving compartment syndrome symptoms as invasive open techniques. After surgical intervention, the patient reported a 90% reduction in symptoms and had returned to full sport participation within two months." }, { "id": "pubmed23n0844_3063", "title": "Multiprobe devices for exercise transcutaneous oxymetry in patients complaining claudication: interest and limits of unusual probe positions.", "score": 0.008695652173913044, "content": "Exercise transcutaneous oximetry (PtcO2) can argue for a vascular origin of exercise-related pain in atypical unusual localizations, such as lumbar, thigh or foot pain.

We report a case of COVID-19 myocarditis in an elite athlete. A male, 21-year-old elite football player had tested positive for SARS-CoV-2 on a polymerase-chain-reaction test and was referred for cardiac evaluation after experiencing palpitations after returning to sports (RTS). Biochemical evaluation demonstrated elevated N-terminal pro b-type natriuretic peptide (NT-proBNP) and high-sensitive Troponin T. Echocardiography demonstrated left ventricular function within normal ranges for athletes but with diminished basal, posterolateral, and septal strain. Cardiac magnetic resonance imaging (CMR) showed increased T1 values and late gadolinium enhancement (LGE) in the basolateral and mid-ventricular posterior segments. Focal COVID-19 myocarditis was diagnosed and the patient remained restricted from sports, in line with the 2020 ESC sports cardiology guidelines. Two months later, his electrocardiogram (ECG) showed inferoposterolateral T-wave inversion (TWI). Serial imaging studies were performed to optimize RTS timing. Cardiac magnetic resonance imaging showed persistently increased T1/T2 values and persistent LGE at 5 and 7 months. At 9 months, 18 F-fluorodeoxyglucose (FDG)-positron emission tomography (PET)-computerized tomography (CT) demonstrated no pathologically increased cardiac FDG-uptake. Subsequent exercise ECG and Holters demonstrated no complex ventricular arrhythmias. The patient made a complete return to elite competitive sports, without any adverse events at 15 months of follow-up. Cardiac symptoms in athletes post-COVID-19 should prompt cardiac evaluation. As COVID-19 myocarditis inflammation can persist beyond the 3-6 months of recommended sports restriction, a more personalized approach to RTS timing can be warranted. In cases with myocardial oedema without other signs of inflammation, FDG-PET-CT can be of added value to assess active myocardial inflammation." } ] } } }

The advance in diagnosis and treatment of congenital heart defects has become very important because mortality has diminished and patients live longer and better, reaching adult hood. Molecular biology offers now opportunities understand the cause of many genetic diseases thanks to molecular studies of chromosomes. Conotruncal malformations are known to be caused by a microdeletion in chromosome 22(22q11), this mutation is also responsible for the DiGeorge and cardiovelofacial syndromes, the most relevant aspects are: congenital heart disease, which is present in 75% of the cases, the leading disorder is Fallot's tetralogy with pulmonary atresia, in second place is interruption of the aortic arch type B, followed by common truncus arteriosus. These patients have other phenotypic features, such as high palate, speech problems, malimplantation of ears, and protuberant nose tip, among others.

Furthermore, new phenotypes have been recently recognized, most of them belonging to the psychiatric spectrum. Descriptive studies of large samples of children with 22q11 deletion, conducted, both in the United States and european countries, have shown the following pattern of associated symptoms:--abnormal face (100%), which expression varies with age, and can be discrete;--cardiac abnormalities (84%), including cardiac malformations of conotroncal types;--mouth abnormalities (49%), including cleft palate (14%), and velar dysfunction (20%);--urinary tract abnormalities (36%), including ureteric reflux, lung dysplasia;--transitory hypocalcemia (60%) mostly during infancy, and due to transitory hypoparathyroid dysfunction;--seizures (21%), which are usually a consequence of hypocalcemia;--immunodeficiency (1%), which worsens the prognosis. Deletion of chromosome 22q11 has been also associated with various psychiatric phenotypes, which can be classified into two groups, developmental abnormalities and psychiatric conditions. The great majority of patients with the deletion exhibit impairment of language and motor development, mild mental retardation, persistent coordination deficits, and poor academic performance. The deletion of chromosome 22q11 is also associated with high frequency of behavioral disorder with attention deficit during childhood, and with high frequency of psychotic disorder (bipolar disorder, and schizophrenia) during adolescence and young adulthood. The link between the 22q11 deletion and schizophrenia has been also supported by recent studies showing that the rate of 22q11 deletion in adults with schizophrenia (2%) is higher than it is in the general population. The rate may even be higher (6%) in subjects with childhood onset schizophrenia. The present work reviews the psychiatric literature associated with 22q11 deletion.

It is characterized by congenital heart disease, mainly supravalvular aortic stenosis, mental retardation, mild short stature, facial dysmorphisms, and variable abnormalities in different systems. Objectives. To report the clinical findings of 55 Brazilian patients confirmed by multiplex ligation-dependent probe amplification (MLPA). Methods. Patients were followed up for 4 years at the Genetics Unit of the Instituto da Criança of the Hospital das Clínicas, FMUSP, Brazil. A kit specific for WBS was used to detect the 7q11.23 microdeletion. Results. Two patients with negative FISH results had positive MLPA results for WBS. The characteristics of the patients with the deletion were as follows: typical WBS facies (98.2%), neuropsychomotor delay (98.2%), hypersocial behavior (94.5%), hyperacusis (94.5%), and congenital heart disease (81.8%). Conclusions. MLPA was effective in detecting the microdeletion in the 7q11.23 region to confirm the diagnosis of WBS.

The aim of our study was to assess the long and short term efficacy and tolerance of this molecule in this disease. The case reports of 64 patients presenting with severe, recurrent aphthous stomatitis treated with colchicine between 1986 and 2000 were analyzed retrospectively. Only immunocompetent patients exhibiting idiopathic aphthous stomatitis or Behçet's disease were included. Ten patients were excluded: 4 cases of Behçet's disease treated with colchicine and systemic corticosteroids, 4 cases of aphthous stomatitis secondary to a hematological cause and 2 patients who were lost to follow-up after 3 month's treatment. Colchicine was prescribed at a dose of 1 to 1.5 mg/d for at least 3 months. All the patients were assessed after 3 month's treatment and all were contacted by phone in May 2000. Our end-point criteria were: the frequency and duration of the episodes, intensity of pain and impact on the quality of life of the patients. Fifty-four patients were included: 39 women (mean age=44 +/- 16.8) and 15 men (mean age=49 +/- 13.5). The disease had progressed for a mean of 11.6 +/- 13.5 years. After 3 month's treatment, 12 patients (22 p. 100) no longer had aphta and were in complete remission, 22 patients (41 p. 100) were significantly improved, since the frequency and duration of the lesions had decreased by at least 50 p. 100 and the latter were no longer painful. Treatment failed or tolerance was poor in 20 patients (37 p. 100). Patients were monitored and assessed for a mean of 4.7 years (range: 6 months to 13 years). Six patients were lost to follow-up. Three patients (6 p. 100) were considered as cured, since they were still in complete remission after suspension of colchicine respectively 6, 24 and 72 months later. Fifteen patients (31 p. 100) had still improved. Among the latter, 10 continued colchicine for a mean of 27 months, and 5 patients stopped treatment, which they considered tedious, after a mean of 16 months. These 15 patients noted a significant reduction in the frequency and duration of the lesions. Moreover, the subjective end-point criteria had improved significantly for them not to wish to change treatment. Thirty patients (63 p. 100) were not improved by the treatment. Some benign adverse events were noted in 10 patients (18.5 p. 100) and led to suspension of treatment in 4 cases. This study, which is the first in size (n=54) and duration of follow-up (4.7 years), showed that colchicine is an efficient preventive treatment of severe aphthous stomatitis for 63 p. 100 of patients after 3 month's treatment and that this improvement was lasting in 37 p. 100 of them.

Four patients underwent bypass surgery and they have been followed for 10 to 28 months. Three are free of angina and one has only minimal angina. One patient refused surgery and he continued to have severe angina despite intense medical treatment. He died suddenly after 30 months follow-up. In patients with complete occlusion of the left main coronary artery, development of adequate collateral flow seems important in preserving left ventricular function, but collaterals are usually insufficient to prevent angina.

Fifty-eight patients received medical treatment (Group I), 12 had PTCA (Group II) and 23 had CABG (Group III). Findings of coronary angiography, treadmill exercise tests and dipyridamole perfusion scintigraphy as well as the frequency of cardiac events during follow-up were assessed in each group. 1. Coronary angiography revealed 1 vessel disease in 38% of the patients in Group I, 58% in Group II, and 13% in Group III; 2 vessel disease in 33%, 25% and 61%; and 3 vessel disease in 29%, 17% and 26%, respectively. 2. Exercise duration with the treadmill test was 4.7 min in Group I, 4.0 min in Group II and 3.7 min in Group III.

Diameters of left atrium and ventricle, LVEF and wall motion score index (WMSI) were calculated. During 1 year 8 patients died (5 of them during perioperative period and 3 patients during follow-up). Patients in group I before operation were in higher NYHA and CCS class and had more often myocardial infarction. During each of the five echocardiographic examination the values of LVEF and WMSI did not differ between subgroups Ia vs Ib and IIa vs IIb. In group I, especially in patients with very low LVEF &lt; or = 30%, the values of LVEF and WMSI improved significantly (p &lt; 0.001) during 1 year of follow-up.

Therapeutic strategies for the prevention or retardation of GCD in the cardiac allograft are limited; palliative coronary revascularization has been attempted. Because of the high mortality rate associated with advanced forms of GCD our institution offers the option of retransplantation in selected cases. The aim of this study was by analyzing retrospectively the outcomes of angioplasty, coronary bypass grafting, and retransplantation in cardiac transplant patients to attempt to identify subgroups of transplant recipients with graft coronary disease who may profit from myocardial revascularization. Of the 989 patients undergoing 1016 heart transplantations (HTx) at our institution between 10/86 and 12/97, all were screened for the development of GCD. Analyzing routinely annual angiography, intracoronary ultrasound in defined study patients, and autopsy findings, GCD was diagnosed in 124 patients (110 male, 14 female) 2 to 107 months after HTx (mean 30 months). PTCA: Fourty-six out of 124 patients underwent 76 angioplasties at a mean of 50 +/- 30 months (range 4-91 mo) following cardiac transplantation. The primary success rate was 96% (73/76). The reason for the unsuccessful angioplasty attempts (n = 3) was failure to completely penetrate a stenosis of LAD in 2 patients and severe dissection of RCA, which required emergency surgery, in one. Angiographic restenosis occurred in 42% (31 of 76 lesions) and was diagnosed 11 +/- 11 months after the first angioplasty. There was no procedure-related death. CABG: Seven patients underwent bypass surgery at a mean of 67 months (range 6-128 months) after HTx. Elective surgery was performed in 2 patients with proximal severe triple-vessel disease (Type A lesion) and in 1 patient with severe tricuspid regurgitation who received a tricuspid valve replacement and concomitant single-vessel bypass surgery for proximal GCD (Type A lesion). One patient with combined Type A and B/C lesions required emergency surgery for dissection of RCA after an angioplasty procedure. Three patients with post-infarction unstable angina developed worsening congestive heart failure which required emergency surgery. Angiographically all these patients showed diffuse, distal arteriopathy (combined Type B/C lesions). The electively operated patients and the patient with dissection of RCA were successfully treated and survived beyond hospital discharge (overall survival for CABG in GCD patients 4/7 = 57%). After a mean follow-up of 10 months (range 2-32 months) all are in good clinical condition. All 3 patients with distal arteriopathy and emergency surgery died in hospital of left-ventricular failure (43%). Retransplantation: Eight patients underwent retransplantation at a mean of 54 months (range 6-96 months) after HTx. Six of 8 patients had successful operations and survived beyond hospital discharge with a one-year-survival rate of 75%. In a mean follow-up of 31 months (5-68 months) 3 of 6 retransplant recipients developed a recurrence of GCD. The presence of angiographic distal arteriopathy should be considered a significant factor in patient selection for coronary revascularization procedure. Coronary angioplasty is to be considered as a method of treatment for severe, local stenoses (Type A lesion). PTCA may be applied in these selected cardiac transplant recipients with primary success and complication rates comparable to routine angioplasty but with an increased rate of restenosis especially in small vessels (diameter &lt; 2.5 mm). The distinction between Type A lesions in large (diameter &gt; or = 2.5 mm) and small vessels may be important not only with respect to restenosis but also with respect to long-term benefit. The overall survival did not differ between GCD patients with and without PTCA, suggesting this treatment to be largely palliative.

At 5 hours after onset, ECG showed significant upsloping ST depression at J point in precordial leads V3 to V6, slight ST elevation in aVR and depression in inferior leads, and hs-cTnI peaked at 2.610 μg/L. The diagnosis of de Winter ECG pattern was confirmed by coronary angiography with an occlusion of the proximal LAD. A stent was implanted through percutaneous coronary intervention. The patient's chest pain was relieved without further increase of hs-cTnI. ECG after procedure showed ST segment back to baseline in leads V4 to V6, but persistent ST elevation in V1 to V3 with QS or Q wave. Timely diagnosis of de Winter ECG pattern is very important, especially the atypical and delayed ECG changes. It should be treated as ST elevation myocardial infarction equivalent and deserves emergent revascularization therapy." }, { "id": "pubmed23n0043_6822", "title": "[Constriction of the left main coronary artery.

Both revascularization techniques resulted in greater symptomatic relief and a lower incidence of ischemia on the treadmill test; however, all three strategies eventually resulted in the abolition of limiting angina. The more aggressive therapeutic approach with initial bypass surgery for patients with a single severe proximal stenosis of the left anterior descending coronary artery is associated with a lower incidence of medium-term adverse events than coronary angioplasty or medical treatment. However, all three strategies resulted in a similar incidence of death and infarction during an average follow-up period of 3 years.

Coronary bypass graft procedures can achieve an immediate augmentation in coronary blood flow distally through the involved vessel and thereby improve myocardial perfusion and oxygen delivery and thus have the potential for reversing myocardial ischemia both acutely and for the long term. Although myocardial revascularization may resolve the ventricular functional alterations associated with acute myocardial ischemia it remains uncertain whether revascularization can reverse ischemic myocardial cellular injury and in what time framework, as related to reversible vs. irreversible ischemic cellular changes. Mechanical circulatory assistance (MCA) using diastolic counterpulsation effectively reduces myocardial ischemia by the physiologic mechanisms of 1) decrease in left ventricular after-load and left ventricular wall tension, 2) improvement is cardiac output by diastolic counterpulsation and 3) augmentation of coronary blood flow by diastolic pressure augmentation. The most effective indication for either MCA or myocardial revascularization is for interruption of myocardial ischemia prior to the development of infarction. Clinical sudies have demonstrated that acute myocardial ischemia can be effectively interrupted by intraaortic balloon pumping (IABP) including reversal of left ventricular dysfunction associated with acute myocardial ischemia. In most instances, cessation of IABP resulted in recurrence of myocardial ischemia indicating the need for urgent revascularization surgery. In the management of medically refractory myocardial ischemia.

The Authors hereby report the case of a 91-year-old diabetic man who underwent coronary angiography in June 2005 for subacute unstable angina. Angiography disclosed a critical stenoses in the distal unprotected left main, left anterior descending, and distal left circumflex, which were treated with a paclitaxel-eluting stent and a bare-metal stent (BMS), respectively. Four months later, recurrent angina lead to a second angiography which showed critical restenosis in the left anterior descending and significant ostial stenosis in the left circumflex. Another paclitaxel-eluting stent was implanted in the left anterior descending, followed by kissing balloon in the left main, achieving a good angiographic result. Six months later angina recurred again: at angiography diffuse restenosis in the left main, left anterior descending and left circumflex was documented. A crushing technique was thus employed to deliver 2 sirolimus-eluting stents, achieving a satisfactory final result. Since then, and to date for more than 17 months since the last procedure, this nonagenarian has remained free from anginal chest.

In the absence of these prognostic variables in patients with eigher two or three vessel disease the outlook is so good that early surgery is unlikely to increase the prospect of survival.

The pathophysiology of cardiogenic shock is characterized by a downward spiral: ischemia causes myocardial dysfunction, which, in turn, augments the ischemic damage and the energetical imbalance. With conservative therapy, mortality rates for patients with cardiogenic shock are frustratingly high reaching more than 80%. Additional thrombolytic therapy has not been shown to significantly improve survival in such patients. Emergency cardiac catheterization and coronary angioplasty, however, seem to improve the outcome in shock-patients, which most probably is due to rapid and complete revascularization generally reached by angioplasty. In addition to interventional therapy with rapid coronary revascularization, the use of mechanical circulatory support may interrupt the vicious cycle in cardiogenic shock by stabilizing hemodynamics and the metabolic situation. Different cardiac assist devices are available for cardiologists and cardiac surgeons: 1. intraaortic balloon counterpulsation (IABP), 2. implantable turbine-pump (Hemopump), 3. percutaneous cardiopulmonary bypass support (CPS), 4. right heart, left heart, or biventricular assist devices placed by thoracotomy, and 5. intra- and extrathoracic total artificial hearts. Since percutaneous application is possible with IABP, Hemopump and CPS, these devices are currently used in interventional cardiology. The basic goals of the less invasive intraaortic balloon counterpulsation (IABP; Figure 1) are to stabilize circulatory collapse, to increase coronary perfusion and myocardial oxygen supply, and to decrease left ventricular workload and myocardial oxygen demand (Figure 2). Since the advent of percutaneous placement, IABP has been used by an increasing number of institutions (Figure 3). In addition to cardiogenic shock, the system may be of use in a variety of other indications in the catheterization laboratory and intensive care unit, including weaning from percutaneous cardiopulmonary bypass, in ischaemic left ventricular failure, in unstable angina, in high risk PTCA, and in prophylactic support in patients with myocardial infarction and successful revascularization. Animal experimental data showed that IABP may improve success of thrombolysis and recent clinical data suggest that survival is enhanced and transfer for revascularization is facilitated when patients with myocardial infarction and cardiogenic shock undergo thrombolysis and IABP rather than thrombolysis alone. A lot of studies had demonstrated before, that combined use of counterpulsation and revascularization therapy (i.e. coronary bypass surgery or angioplasty) may improve prognosis in patients with myocardial infarction complicated by cardiogenic shock (Table 1). In such patients, early treatment with IABP is most important: Multivariate analysis identified early IABP-support with a duration of shock to IABP-treatment of &gt; or = 4 hours as an independent predictor of a positive short-term outcome. In shock-patients with postinfarction ventricular septal defect, IABP provides a marked hemodynamic improvement, and a significant decrease in shunt-flow (Figure 5). However, despite initial stabilization with IABP, such patients need immediate surgical repair of the septal defect to avoid hemodynamic deterioration. The rate of complications related to percutaneous IABP was significantly attenuated by employing catheters of reduced size. Using 9.5-F catheters, a long duration of counterpulsation emerged as the most significant factor associated with complications. In our hospital, those patients with 9.5-F catheters in whom counterpulsation did not exceed 48 hours had a low complication rate of 3.9%. The Hemopump is a catheter-mounted transvalvular left ventricular assist device intended for surgical placement via the femoral artery (Figures 6 and 7).

Each method of stress testing was quantified: the exercise ECG by means of an ischemia score, incremented with increasing ST-segment depression and decremented as a function of duration of exercise and workload in watts; thallium-201 scintigraphy by means of an index for minimal to maximal perfusion region (vitality index) and redistribution factors; equilibrium-radionuclide ventriculography by means of global ejection fraction and maximum systolic volume change with respect to the end-diastolic volume. The patients were divided into three groups: 30 had successful TCA defined as demonstrating at least a 20% reduction in the stenosis; six underwent aortocoronary bypass operation (nine grafts; complete revascularization in four patients); and in six patients TCA was unsuccessful. TCA was successful in 24 LAD stenoses, 5 RCA stenoses, and in one proximal anastomosis of an aortocoronary bypass graft. Dilatation could not be achieved in three LAD stenoses and three stenoses of the RCA. In those in whom it was successful, TCA yielded an average reduction of coronary artery stenosis from 84 to 43%. Both TCA and bypass operation (OP) led to comparable degrees of functional improvement. The ischemia score decreased from 2.8 to 0.9 after TCA and from 1.6 to 0 after OP.

Both are rare, with TEN and SJS affecting approximately 1or 2/1,000,000 annually, and are considered medical emergencies as they are potentially fatal. They are characterized by mucocutaneous tenderness and typically hemorrhagic erosions, erythema and more or less severe epidermal detachment presenting as blisters and areas of denuded skin. Currently, TEN and SJS are considered to be two ends of a spectrum of severe epidermolytic adverse cutaneous drug reactions, differing only by their extent of skin detachment. Drugs are assumed or identified as the main cause of SJS/TEN in most cases, but Mycoplasma pneumoniae and Herpes simplex virus infections are well documented causes alongside rare cases in which the aetiology remains unknown. Several drugs are at \"high\" risk of inducing TEN/SJS including: Allopurinol, Trimethoprim-sulfamethoxazole and other sulfonamide-antibiotics, aminopenicillins, cephalosporins, quinolones, carbamazepine, phenytoin, phenobarbital and NSAID's of the oxicam-type. Genetic susceptibility to SJS and TEN is likely as exemplified by the strong association observed in Han Chinese between a genetic marker, the human leukocyte antigen HLA-B*1502, and SJS induced by carbamazepine. Diagnosis relies mainly on clinical signs together with the histological analysis of a skin biopsy showing typical full-thickness epidermal necrolysis due to extensive keratinocyte apoptosis. Differential diagnosis includes linear IgA dermatosis and paraneoplastic pemphigus, pemphigus vulgaris and bullous pemphigoid, acute generalized exanthematous pustulosis (AGEP), disseminated fixed bullous drug eruption and staphyloccocal scalded skin syndrome (SSSS). Due to the high risk of mortality, management of patients with SJS/TEN requires rapid diagnosis, evaluation of the prognosis using SCORTEN, identification and interruption of the culprit drug, specialized supportive care ideally in an intensive care unit, and consideration of immunomodulating agents such as high-dose intravenous immunoglobulin therapy. SJS and TEN are severe and life-threatening. The average reported mortality rate of SJS is 1-5%, and of TEN is 25-35%; it can be even higher in elderly patients and those with a large surface area of epidermal detachment. More than 50% of patients surviving TEN suffer from long-term sequelae of the disease." }, { "id": "pubmed23n0666_16732", "title": "Severe carbamazepine-induced cutaneous reaction in the treatment of post-herpetic neuralgia. Case report.", "score": 0.017470247177296307, "content": "Post-herpetic neuralgia (PHN) is the main complication of herpes zoster. Carbamazepine (CBZ), a well-tolerated anticonvulsant, but frequently associated with severe cutaneous reactions, such as the Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) is used in the treatment of this complication. The objective of this article was to report a case of SJS/TEN secondary to CBZ in a patient with PHN. This is a female patient with continuous severe, burning, chock-like pain in the thoracic region and dorsum associated with reduced strength in the ipsilateral upper limb and diaphoresis. She had crusty and erythematous lesions in the dorsal region of the thorax with allodynia and dysesthesia in the affected dermatome. She was treated with CBZ 300 mg.day(-1), amitriptyline (AMT) 12.5 mg at bedtime, and infiltration with local anesthetic in the affected region. After 15 days, she developed malaise, fever, muscle pain, and arthralgia with a mild non-specific cutaneous rash. Carbamazepine was discontinued immediately. One week later, she was hospitalized with urticaria, generalized exanthema, erythematous cutaneous eruptions, bullae, and purpuric maculae all over her body. The impression was of carbamazepine-induced SJS/TEN. She evolved with progressive worsening of her symptoms, with increase in the number and size of cutaneous lesions, besides generalized erythematous macular rash, areas of necrosis, and erosions with symmetrical loosening of the epidermis in face, neck, thorax, dorsum, and limbs, affecting more that 50% of her body surface, besides involvement of buccal, conjunctival, and genital mucosa with vesicular erosions. She had progressive functional worsening, evolving to septic shock and multiple organ failure followed by death. Stevens-Johnson syndrome and toxic epidermal necrolysis are severe cutaneous reaction with potential for elevated morbidity and mortality that requires immediate intervention and adequate management. In addition, we would like to alert that the use of Carbamazepine should be supervised, especially in the elderly." }, { "id": "pubmed23n1164_2609", "title": "Toxic Epidermal Necrolysis: A Case Report on a Drug-Induced Phenomenon.", "score": 0.0164021164021164, "content": "Toxic epidermal necrolysis (TEN) is a group of severe forms of several life-threatening conditions. As a co-infection of this group, Stevens-Johnson syndrome (SJS) is a rare though severe disease of the skin and mucous membranes. Intake of some drugs could cause reactions such as SJS and TEN. A form of severe connective tissue disorder, TEN is also known as Lyell's syndrome and is a common cause of significant skin and mucous membrane disintegration. Adverse medication reactions are the most prevalent and contribute highly to the incidence rates of the major etiological variables for TEN. Erythema, epidermal detachment that manifests as blisters, and denuded skin patches are the defining features of this pathology. In the majority of cases, the administration of pharmaceutical drugs is thought to be the primary cause of SJS/TEN. In this article, we report a case of a 33-year-old male patient who presented with complaints of lower left facial pain and thus was prescribed carbamazepine. Following this, the patient presented with an adverse reaction to the administration of carbamazepine and was taken off the drug immediately. The treatment included the administration of hydration therapy and appropriate antibiotics for treating the fluid-filled vesicles.

Toxic epidermal necrolysis also known as Lyell's syndrome was first described by Lyell in 1956. Drugs are by far the most common cause of toxic epidermal necrolysis, in which large sheets of skin are lost from the body surface making redundant the barrier function of the skin, with its resultant complications. Drug-induced toxic epidermal necrolysis are severe adverse cutaneous drug reactions to various precipitating agents that predominantly involve the skin and mucous membranes. Toxic epidermal necrolysis is rare but considered medical emergencies as they are potentially fatal. Drugs are the most common cause accounting for about 65%-80% of the cases. The most common offending agents are sulfonamides, NSAIDs, butazones and hydrantoins. An immune mechanism is implicated in the pathogenesis, but its nature is still unclear. There is a prodormal phase in which there is burning sensation all over the skin and conjunctivae, along with skin tenderness, fever, malaise and arthralgias. Early sites of cutaneous involvement are the presternal region of the trunk and the face, but also the palms and soles, rapidly spread to their maximum extent, the oral mucosa and conjunctiva being affected. Initial lesions are macular, followed by desquamateion, or may be from atypical targets with purpuriccenters that coalesce, from bullae, then slough. The earlier a causative agent is withdrawn the better is the prognosis. Several treatment modalities given in addition to supportive care are reported in the literature, such as systemicsteroids, high-dose intravenous immunoglobulins, ciclosporin, TNF antagonists. Recovery is slow over a period of 14-28 days and relapses are frequent. Mortality is 25%-50% and half the deaths occur due to secondary infection. Here we report a 50-year-old female of drug-induced toxic epidermal necrolysis. She was admitted to the dermatology ward with extensive peeling of skin over the trunk and limbs. She had taken alamotrigine for epilepsy. A week after taking the tablets, the patient developed a severe burning sensation all over the body and followed by a polymorphic erythematous dermatitis and widespread peeling of skin.

Based on review of case histories and photographs of patients, a group of experts proposed a classification based on the pattern of erythema multiforme-like lesions (categorized as typical targets, raised or flat atypical targets, and purpuric macules) and on the extent of epidermal detachment. An atlas illustrating this classification that included photographs and schematic drawings was developed. We compared the evaluations of 28 cases by four nonphysicians relying on the atlas with the evaluations of the same cases by five experts not using the atlas to determine the usefulness of this atlas for classifying cases according to our nosologic schema. The following consensus classification in five categories was proposed: bullous erythema multiforme, detachment below 10% of the body surface area plus localized \"typical targets\" or \"raised atypical targets\"; Stevens-Johnson syndrome, detachment below 10% of the body surface area plus widespread erythematous or purpuric macules or flat atypical targets; overlap Stevens-Johnson syndrome-toxic epidermal necrolysis, detachment between 10% and 30% of the body surface area plus widespread purpuric macules or flat atypical targets; toxic epidermal necrolysis with spots, detachment above 30% of the body surface area plus widespread purpuric macules or flat atypical targets; and toxic epidermal necrolysis without spots, detachment above 10% of the body surface area with large epidermal sheets and without any purpuric macule or target. Using the atlas, the nonexperts showed excellent agreement with the experts. This study suggests that an illustrated atlas is a useful tool for standardizing the diagnosis of acute severe bullous disorders that are attributed to drugs or infectious agents. Whether the five categories proposed represent distinct etiopathologic entities will require further epidemiologic and laboratory investigations." }, { "id": "pubmed23n0668_6781", "title": "Stevens-Johnson syndrome-toxic epidermal necrolysis (SJS-TEN) overlap associated with carbamazepine use.", "score": 0.01466795615731786, "content": "A benign pruritic rash occurs in 10%-15% of persons treated with carbamazepine.

DIHS is a systemic autoimmune condition that presents with mucocutaneous lesions of varying severity and comprises 3 subtypes: toxic epidermal necrolysis, Stevens-Johnson syndrome, and drug reaction with eosinophilia and systemic symptoms (DRESS). Here, we describe the case of a 51-year-old woman with a diagnosis of DIHS associated with carbamazepine, reactivation of HHV-6, and acute liver failure, which was consistent with DRESS. CASE REPORT We present the case of a 51-year-old Japanese woman who had been taking carbamazepine for epilepsy for the past 3 weeks. She presented with a fever, liver dysfunction, eosinophilia, and the sudden appearance of a skin rash. Steroid therapy was started for suspected drug-induced liver injury. The skin eruption disappeared, and liver dysfunction showed an improving trend. However, after stopping steroid, the pyrexia and eosinophilia reappeared. Therefore, prednisolone was re-administrated. HHV-6 DNA was detected, so HHV-6 reactivation was confirmed. Carbamazepine was stopped, and the clinical manifestations improved. She was ultimately diagnosed with DIHS, consistent with DRESS, associated with carbamazepine and HHV-6 reactivation, and liver dysfunction was assessed histologically. Therefore, the drug-related hepatotoxicity of carbamazepine played a role in causing liver damage rather than HHV-6 infection at that time. CONCLUSIONS We describe a case of DIHS that was also associated with acute liver failure, consistent with DRESS. The case highlights the importance of making the correct diagnosis, as well as the management of mucocutaneous lesions and other systemic conditions (including acute liver failure)." }, { "id": "pubmed23n0648_2252", "title": "Severe cutaneous reactions caused by barbiturates in seven Iranian children.", "score": 0.013898601398601398, "content": "The severe adverse cutaneous reactions of erythema multiforme (EM), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare mucocutaneous diseases associated with significant morbidity and mortality.

In this article, we present seven children with severe adverse cutaneous reactions caused by barbiturates. The age of the affected children was between 2 and 11 years and they all had a history of taking barbiturates. Their symptoms started 1-3 weeks after the initiation of barbiturates, including a prodrome characterized by 2-3 days of malaise, fever, cough and anorexia, after which the skin and mucosal lesions appeared and worsened. The skin lesions varied from rash to large bullae, plus different forms of mucous membrane involvement. The offending drugs (barbiturates) were stopped immediately and care was largely supportive. As a result of the morbidity and/or mortality associated with EM, SJS and TEN, physicians should keep in mind their differential diagnosis when cutaneous reactions are observed in patients undergoing barbiturate therapy. Furthermore, although TEN and SJS are life-threatening diseases, early detection and appropriate care can lead to a decrease in the incidence of death.

We report an eventful case of a 22-year-old lady who suffered and recovered from carbamazepine-induced SJS/TEN overlapping during her pregnancy. Our patient had a history of epilepsy for which she was under sodium valproate. Switching to carbamazepine due to its low teratogenicity led our patient to this condition. History of prodromal symptoms and exposure to carbamazepine helped in the diagnosis. Carbamazepine abstinence and a multidisciplinary approach in symptomatic management worked very well for the patient. Carbamazepine-induced TES/SJS manifests multisystem effects and requires a multidisciplinary approach for management. The condition itself is life-threatening and in its addition, their sequelae further threaten the life of the patients. Early intervention is the key. Genetically susceptible are thought to be the ones carrying human leukocyte antigen B*15:02 (HLA-B*15:02) allele and it is most prevalent in South-East Asian populations. Screening of this allele before using carbamazepine prevents the incidence of carbamazepine-induced SJS/TEN. Prodromal symptoms of carbamazepine-induced SJS/TEN constitute flu-like symptoms that should not be missed.

Prevalence of COPD among cigarette smokers is about 23% in Poland. Effort dyspnea which develops in advanced stage of COPD is the leading cause of seeking medical advice. Physical activity among patients with PAD is reduced due to intermittent claudication. It may cause delayed COPD diagnosis in this group of patients. To estimate the prevalence of COPD among patients suffering from severe PAD who were hospitalized in surgery department due to critical limb ischemia and to evaluate difficulties during COPD diagnosis in this group of patients. We examined 64 patients suffering from severe PAD (at least IIb stage according to Fontaine's scale). Patients were asked about the typical symptoms of COPD: chronic cough, regular sputum production and dyspnea. To evaluate the intensity of dyspnea we used British Medical Research Council scale. Spirometry was performed to every patient. Patients with airways obstruction underwent spirometry after the administration of inhaled bronchodilator. Every patient who had the post-bronchodilator value of FEV,/FVC ratio below the lower limit of normal values was diagnosed with COPD. It was not possible to evaluate the dyspnea intensity using MRC scale in 44% of 34 patients who reported dyspnea. During the study we diagnosed 16 patients with COPD (9 pts had 1st stage of COPD according to GOLD classification, 7 pts--2nd). 9 patients had been formerly diagnosed with COPD (2 pts--1st stage, 5 pts--2nd, and 2 pts--3rd). Spirometry-defined COPD was present in 39% of study group. The analysis of data from patients with PAD coexistent COPD revealed that 60% of them were current cigarette smokers and 28% of them declared passive smoking exposure. The other known negative prognostic factors in patients with COPD such as BMI lower than 21 kg/mr2, FEV1% of predicted value below 65% and X-rays photograph visible emphysema were observed in 40%, 32% and 12% of patients with PAD and coexistent COPD respectively. Hypertension was present in 52% of patients with PAD and coexistent COPD, cardiac arterial disease in 52% and chronic heart failure due to cardiac arterial disease in 36%. Further analysis of laboratory tests revealed dyslipidemia and chronic kidney disease in 52% and 60% of these patients respectively. COPD diagnosis among patients suffering from severe PAD involves several difficulties such as uselessness of MRC dyspnea scale and frequent heart diseases which delay the COPD diagnosis being considered as primary dyspnea reason. Many factors which have been proven to be responsible for worse prognosis due to COPD were observed in patients with PAD and coexistent COPD. High prevalence of COPD among patients suffering from PAD suggests the spirometry as a COPD screening would be justified in that group." }, { "id": "wiki20220301en020_57455", "title": "Pulmonary artery", "score": 0.009523809523809525, "content": "Clinical significance The pulmonary artery is relevant in a number of clinical states.

Cardiovascular symptoms are represented by a sudden and transient arterial hypertension which can drive to a diagnostic error and electrocardiographic abnormalities, which are directly related with the degree of vasospasm; their evolution is completely regressive. Main intracranial consequences are early hydrocephalus, worsening of consciousness and progressive ventricular distension on CT scan and vasospasm, which occurs between the 4th and the 12th day, may be asymptomatic or symptomatic, responsive for delayed ischemia, followed by deterioration of consciousness and focal neurological signs. The main factors responsible for the vasospasm are a high amount of blood in basal cisterns on CT scan; an increase of substances released by the lysis of hemoglobin in CSF; hyponatremia, hypovolemia, and decrease in cerebral blood flow. Consequences of these disorders have to be well known in the medical treatment before and after operation." }, { "id": "pubmed23n0310_2182", "title": "[Management of subarachnoid hemorrhages without detectable aneurysm].", "score": 0.01406116844995739, "content": "In this study, 21 patients with subarachnoid hemorrhage (SAH) but negative angiography were evaluated. Angiography was performed twice on each patient, that is, on admission and at 2 weeks following admission. All patients had severe headache of sudden onset, a characteristic manifestation of SAH. Clinical grades on admission (Hunt and Kosnik classification) were generally good: 17 patients were in grade I or II and 4 patients were in grade III. SAH was confirmed by the presence of subarachnoid clot on CT in all cases. Based on the distribution of SAH, CT findings were classified into two patterns, i.e., perimesencephalic and non-perimesencephalic patterns. Four patients showed the perimesencephalic pattern and the remaining 17 the non-perimesencephalic. The period of follow-up ranged from 20 days to 11 years 6 months, with a mean of 6 years 10 months. Except for three recent cases, the mean follow-up period in 8 years 9 months. Exploratory craniotomies probing for aneurysms have been performed in four patients, but no aneurysms have been found in any of these cases. Clinical deterioration associated with vasospasm was observed in one patient. A communicating hydrocephalus requiring a shunting procedure was observed in three patients showing the non-perimesencephalic type CT pattern. Rebleeding occurred in one patient who subsequently died of what may be a dissecting aneurysm of the vertebral artery. One patient who was able to return to full activity experienced symptoms attributable to SAH such as frequent headaches and increased fatigability. Complete recovery was observed in the remaining 19 patients. Two of them, however, later died due to myocardial infarction and aging, respectively. Given these generally positive outcomes, it should be possible to inform such patients of the benignity of their condition. Angiography may not demonstrate a ruptured aneurysm on initial examination in all cases of aneurysmal SAH. Serial angiography, however, can provide a definite diagnosis of the dissecting aneurysm. Therefore, repeat angiography, particularly, when possible, digital subtraction angiography, is necessary to rule out aneurysmal SAH. While small aneurysms or microaneurysms are often found through exploratory craniotomy, we do not agree with the opinion that surgery may be appropriate for certain patients with SAH but with negative angiography. The natural history concerning rebleeding in such cases, as well as morbidity and mortality associated with hemorrhage, remains to be defined.

Three methods of investigations were applied: 1. Angioscintigraphy of the brain. 2. Computerized tomography. 3. Clinical evaluation according to GOS (Glasgow Outcome Scale). The results obtained seem to give reasons to assumption that SAH initiates the gradual process of degradation of the CNS tissues. The blood extravasated to the subarachnoid space following aneurysm burst sets in motion a chain of events leading to: 1) impairment of brain arteries reactivity on elevation of pCO2, 2) intensification of brain atrophy. The intensity of the above mentioned phenomena is proportional to the severity of clinical course of SAH.

Therefore, he was transferred to the Pediatric Department of the University Hospital the same night. An emergency CT scan that night showed intracerebral and subarachnoid hemorrhage with enlarged ventricle (Fisher grade 5). Angiography was not available within reasonable time. Thus in the stage of progressively increasing clinical deterioration, still without pupillary signs, an external ventricular drain-age was placed. Immediately after reduction of the cerebrospinal fluid volume, arterial hypertension was noticed--the right pupil was mydriatic and fixed. Without further apparative diagnosis an emergency craniotomy was performed for decompression under the suspicion of a secondary hemorrhage due to a rerupture of a middle cerebral artery aneurysm. A bleeding aneurysm of the right middle cerebral artery was found and clipped. A mass transfusion was necessary and a pulmonary air embolism occurred. The infant died in tabula. The histological specimens revealed disruption of the internal elastic membrane of both MCA. This emphasizes a congenital nature of the aneurysm. We conclude that cerebral arterial aneurysms have to be considered in the differential diagnosis of stroke-like symptoms in infancy and early childhood, although the incidence of reported cases is less than one case per year. Since no valid screening parameter is available, diagnosis is often made only after rupture of the aneurysm. This causes problems for emergency management. Infants and children with stroke or stroke-like symptoms should immediately be transferred to a hospital with a neurosurgical unit." }, { "id": "pubmed23n0052_5394", "title": "[Ruptured intracranial aneurysm.

Case report. Tertiary-care hospital. Fusiform aneurysm of cerebral vessels is a rare pathology that presents with ischemic stroke, subarachnoid hemorrhage, or mass effect. Ischemia and subarachnoid hemorrhage in the same patient 2 days apart, to our knowledge, was not reported before. A 55-year-old Hispanic man with history of untreated hypertension and alcohol abuse presented with acute onset of right hemiparesis and dysarthria. On day 2 of his hospital admission, he developed arrhythmia and loss of consciousness. The patient expired from cardiac arrest on day 4 of his hospitalization. Initial head computed tomography scan showed dolichoectatic basilar artery and marked calcification of internal carotid arteries (ICA) and middle cerebral arteries (MCA). Brain magnetic resonance imaging showed left upper pons infarct 2 cm in diameter. Magnetic resonance angiography confirmed presence of a fusiform aneurysm of the basilar artery. Head computed tomography scan at the time of clinical deterioration on day 2 of hospital admission showed subarachnoid bleeding and significant brain edema. Autopsy revealed a ruptured basilar artery aneurysm with thrombus in the lumen and left pontine infarct. Microscopic examination of fusiform aneurysm showed atherosclerosis of the aneurysmal wall and attenuation and inflammation at the rupture site. We hypothesize that in our case, pontine infarct had developed because of occlusion of pontine perforators by a thrombus within an aneurysm, and subarachnoid hemorrhage had developed secondary to a rupture of weakened by inflammatory changes aneurysmal wall. We also hypothesize that in our case, ischemic stroke and subsequent subarachnoid hemorrhage may represent different stages of the same process of atherosclerosis and inflammation in an aneurysmal wall confirmed by autopsy. Origin as well as management of fusiform cerebral aneurysms are unclear. Antiplatelet agents and anticoagulation are recommended by some for stroke prophylaxis in patients with unruptured fusiform cerebral aneurysms. Our case shows that caution should be exercised in prescribing anticoagulants or even antiplatelet agents to a patient with fusiform aneurysm of cerebral arteries due to a possibility of rupture of an aneurysm.

In spite of extensive research, the pathogenesis of vasospasm remains obscure, and clinical management has so far been extremely difficult. For the evaluation of the efficacy of any treatment and the timing of operation, the development and resolution of the arterial narrowing should be monitored. It is important to know the correlation between the change in flow velocity and the course of clinical symptoms. In this study, the blood flow velocity in the different arteries was measured at short intervals (at least every third day) with transcranial Doppler ultrasonography, in eighteen patients with ruptured cerebral aneurysm. Flow velocity changes began to accelerate from 3 days after surgery, and reached the maximum value between 7 and 10 days, with normalization occurring within the following 2 weeks. The changes showed a significant relationship to the severity of vasospasm, the side of the operative approach, and the administration of calcium antagonist. Based on our results, we categorized the flow velocity changes of vasospasm for clinical practice as follows. (1) A slight acceleration of up to 120 cm/s in MCA and 90 cm/s in ACA was defined as within the normal range. In this state vasospasm was never observed angiographically. (2) Flow velocity changes between 120 and 140 cm/s were a subcritical state. These changes were seen in vasospastic patients who did not develop ischemic deficits. (3) Flow velocity changes of over 140 cm/s in MCA and 100 cm/s in ACA were critical vasospasm, since all of the patients who developed ischemic symptoms were in this group. Velocity changes higher than 170 cm/s in MCA and 130 cm/s in ACA seem to indicate a critical condition with a tendency to develop into brain infarction. The comparison between the time course of the flow velocity changes and clinical status showed that in symptomatic vasospasm the increase in velocity occurred before the manifestation of clinical symptoms. The transcranial Doppler measurements help to identify those patients who have a high risk of developing neurological deficits due to vasospasm, and help to select those who would benefit from preventive treatment in asymptomatic stage." }, { "id": "pubmed23n0316_774", "title": "[Two cases of subarachnoid hemorrhage associated with neurofibromatosis type I: a case of multiple cerebral aneurysms and arteriovenous malformation, and another case of an anterior communicating artery aneurysm].", "score": 0.008928571428571428, "content": "Two cases of subarachnoid hemorrhage associated with neurofibromatosis type I (von Recklinghausen's disease) are reported.

Arterial vasospasm was demonstrated in 113 of 360 patients (31%).

The ISAT authors conclude that \"when treating ruptured cerebral aneurysms, the advantage of coil embolization over clip ligation cannot be assumed for patients < 40 years old.\" Other subsequent studies have questioned the ISAT's conclusions directly. This conclusion is based on a number of methodological assumptions itself and other authors have cautioned about extending it to other patient populations.

Tremor, usually caused by drugs or essential tremor, is regarded as rather uncommon in children. Arguably, most pediatric patients with tremor do not seek medical attention because of the lack of disability.

Most of the brain is involved in oculomotor control, and thus many neurological conditions present with oculomotor abnormalities. Each of the different classes of eye movements and their features can provide important information that can facilitate differential diagnosis. This educational review presents a clinical approach to eye movement abnormalities that are commonly seen in parkinsonism, ataxia, dystonia, myoclonus, tremor, and chorea. In parkinsonism, subtle signs such as prominent square wave jerks, impaired vertical optokinetic nystagmus, and/or the \"round the houses\" sign suggest early progressive supranuclear gaze palsy before vertical gaze is restricted. In ataxia, nystagmus is common, but other findings such as oculomotor apraxia, supranuclear gaze palsy, impaired fixation, or saccadic pursuit can contribute to diagnoses such as ataxia with oculomotor apraxia, Niemann-Pick type C, or ataxia telangiectasia. Opsoclonus myoclonus and oculopalatal myoclonus present with characteristic phenomenology and are usually easy to identify. The oculomotor exam is usually unremarkable in isolated dystonia, but oculogyric crisis is a medical emergency and should be recognized and treated in a timely manner.

Declining possessive form usage in GD and DS papers has been remarkably uniform over time and has nearly reached completion. PD and AD appear stable in remaining predominantly possessive. The larger volume of papers published in those fields and their possibly greater public recognition and involvement may make that unlikely to change in the short-term. In a secondary analysis restricted to PD, we found that practices have switched dramatically several times in each of three US-published general neurology journals. Meanwhile, in two UK-published journals, and in the specialist title \"Movement Disorders\", the possessive form has been maintained consistently.

PEG was indicated when adequate oral intake of food and fluids proved impossible 8 to 12 days after an acute hypoxaemic cerebrovascular event. 3 of 23 patients who had suffered a stroke, 2 of 8 patients with hypoxaemic brain damage and 3 of 5 patients with decompensated cerebral sclerosis regained the ability to eat between the 21st and 50th day of treatment, so that the gastrostomy could be dispensed with. The other patients died of their severe underlying disease. 6 patients aspirated. In 2 cases this complication occurred during acute aggravation of the underlying disease after several weeks of satisfactory enteral tube feeding. 2 patients aspirated after returning to oral nutrition, whereby feeding was certainly implicated in 1 patient and probable in the other patient. PEG enables adequate enteral nutrition of patients with severe neurological impairment. The advantages of PEG over parenteral nutrition are fewer complications, lower costs and, above all, its superiority in meeting physiological requirements." }, { "id": "pubmed23n1043_5461", "title": "Assessment of the risk of malnutrition due to aspiration pneumonia and oral feeding difficulty.", "score": 0.014827832390576088, "content": "Introduction: many patients with acute-phase swallowing disorders experience malnutrition, which can be caused by oral intake difficulties. Many diseases can cause swallowing difficulties such as aspiration pneumonia, and it is, therefore, necessary to consider the risk of malnutrition during oral feeding therapy in patients with aspiration pneumonia. Objectives: we aimed to evaluate the risk of malnutrition in patients with aspiration pneumonia and other diseases. Methods: the participants comprised 62 patients (45 males, 17 females) with acute-phase swallowing disorders who underwent speech therapy (ST) for swallowing rehabilitation. The patients were divided into four groups: 1) oral feeding with pneumonia, 2) parenteral feeding with pneumonia, 3) oral feeding without pneumonia, and 4) parenteral feeding without pneumonia. The serum albumin and total protein levels were measured to evaluate malnutrition, and swallowing ability was assessed using the Fujishima grade. Results: at the time of ST initiation, serum albumin levels were significantly higher in the oral feeding with pneumonia and oral feeding without pneumonia groups than in the parenteral feeding with pneumonia and parenteral feeding without pneumonia groups. The Fujishima grades differed significantly between the pneumonia/parenteral feeding group and the non-pneumonia/parenteral feeding group. Conclusions: patients with difficulty in swallowing due to aspiration pneumonia were at higher risk of malnutrition than were those without these difficulties. These findings suggest that the nutritional status of parenterally fed patients who developed pneumonia may be inherently poorer than that of orally fed patients." }, { "id": "wiki20220301en045_78674", "title": "Aspiration pneumonia", "score": 0.01326912787586945, "content": "Dysphagia clinicians often recommend alteration of dietary regimens, altered head positioning, or removal of all oral intake.

The ability of clinical interventions to reduce pneumonia incidence is relatively unknown. Dietary modifications or nothing-by-mouth status also have no effect on a patient's ability to handle their own secretions. A patient's individual vigor may impact the development of pulmonary infections more than aspiration. Also increased pneumonia risk exists in patients with esophageal dysphagia when compared to stroke patients because patients with stroke will improve as they recover from their acute injury, whereas esophageal dysphagia is likely to worsen with time.

However it is not beneficial in all cases, and may even prolong the process of dying. The present article discusses the main indications for PEG insertion, and the ethical considerations involved. Three main questions need to be answered: (1) for what purposes should PEG be used; (2) for what type of patients, and (3) when should PEG be inserted in the natural history of the patient's illness? PEG is used in patients unable to maintain sufficient oral intake. It has been found to improve quality of life and/or to increase survival in patients with head and neck cancer, acute stroke, neurogenic and muscle dystrophy syndrome, growth failure (children) and gastric decompression. It led to no improvement in nutritional or functional status in patients with cachexia, anorexia, aspiration (and aspiration pneumonia), and cancer with a short life expectancy. Several court decisions have stipulated that PEG need be offered in patients in a persistent vegetative state or patients with senile dementia who have lost the ability for self-determination. Since the 30-day mortality after PEG insertion is very high for patients hospitalized in a general medical center, a 'cooling off' period of 30-60 days should be scheduled from the time of the PEG request to actual insertion." }, { "id": "pubmed23n0801_25280", "title": "[Nutritional support in stroke patients].", "score": 0.013178428992543782, "content": "Stroke is a public health problem of the first order. In developed countries is one of the leading causes of death, along with cardiovascular disease and cancer. In addition, stroke is the leading cause of permanent disability in adulthood. Many of the patients who survive do so with significant sequelae that limit them in their activities of daily living. Most strokes (80-85%) are due to ischemia, while the rest are hemorrhagic. We have identified many modifiable risk factors, some with an important relationship with dietary factors or comorbidities in wich the diet has a significant impact. The incidence of malnutrition in stroke patients is not well known, but most likely impacts on patient prognosis. Furthermore, the nutritional status of patients admitted for stroke often deteriorates during hospitalization. It is necessary to perform a nutritional assessment of the patient in the early hours of admission, to determine both the nutritional status and the presence of dysphagia. Dysphagia, through alteration of the safety and efficacy of swallowing, is a complication that has an implication for nutritional support, and must be treated to prevent aspiration pneumonia, which is the leading cause of mortality in the stroke patient. Nutritional support should begin in the early hours. In patients with no or mild dysphagia that can be controlled by modifying the texture of the diet, they will start oral diet and oral nutritional supplementation will be used if the patient does not meet their nutritional requirements. There is no evidence to support the use of nutritional supplements routinely. Patients with severe dysphagia, or decreased level of consciousness will require enteral nutrition. Current evidence indicates that early nutrition should be initiated through a nasogastric tube, with any advantages of early feeding gastrostomy. Gastrostomy will be planned when the enteral nutrition support will be expected for long-term (4 weeks). Much evidence points to the importance of glycemic control during hospitalization for stroke. Hyperglycemia at diagnosis and during the first hours of admission impact on patient prognosis. The goal of glycemic control necessary to modify this bad prognosis without adding risk by iatrogenic hypoglycemia is still matter of debate." }, { "id": "pubmed23n0594_2868", "title": "Endoscopic evaluation of neurological dysphagic patients.", "score": 0.01257071024512885, "content": "Dysphagia is a frequent finding in neurological patients and is a symptom related to the severity of the clinical picture.

It cannot be performed in all patients on account of the complexity of the procedure and since they must be brought to the Radiology Unit. In the 1980, a new bedside method was introduced, namely: fiber-optic endoscopic study of swallow (FESS) which is easy, low-cost, well-tolerated and repeatable. We use this bedside technique to assess swallowing function in patients with dysphagia admitted to acute care units, neurological and internal medicine units. The evaluation aims to indicate the safer nutritional method (oral intake, feeding tube or percutaneous gastrostomy) and, consequently, reducing the risk of aspiration pneumonia during hospitalization. We found that more than 50% of the dysphagic patients present cerebrovascular injuries and in 2% of the population, the first diagnostic hypothesis of Myasthenia Gravis can be made with the FESS technique. In 60%, we indicate a change in nutritional method: in 20% we indicate percutaneous endoscopic gastrostomy (PEG). With these indications, none of those patients had aspiration pneumonia.

The reduced caloric or proteic intake due to the motor or cognitive dysfunction, the hypercatabolic state due to infections, the abnormal gastrointestinal motility are the main mechanisms responsible for a state of malnutrition. Between January and December 1999 fourteen patients with chronic neurological diseases were treated. Ten of them had had a stroke, four due to Amyotrophic Lateral Sclerosis (ALS). After the evaluation of nutritional status the patients received enteral nutrition (EN) by placement of a nasointestinal feeding tube or a Bengmark tube. Glycaemia, blood urea nitrogen, serum creatinine, electrolytes, glycosuria, glutamic-oxalacetic and glutamic pyruvic transaminase were monitored in all patients. Polymeric enteral feeding was administered by an infusion pump. Standard nourished patients (7/14) received a 30 Kcal/kg/day support, the undernourished ones (6 low, 1 moderate malnutrition) received a 35-40 Kcal/kg/day support. The complete caloric supply was reached in three-four days. Both of the groups received continuous feeding infusion during hospitalization. For the patients who continued the nutritional support at home (3/14) refeeding was performed only during night-time. In the patients with stroke the optimal/standard weight was reached within one month. In these patients oral nutrition was started within 45 days of treatment taking into account the restored swallowing function. In the patients with ALS the improvement of nutritional standards was reached within the first month and complete restoration within the second/third month.

He was rehospitalized with passage disorders due to eating difficulties such as dysmasesis and dysphagia and an insufficient ability to comprehend meals. Self-care was virtually impossible owing to his lack of understanding of the disease and his dementia. Even if subcutaneous leakage of the subcutaneously implanted port occurred or the connecting portion became dislocated, the patient would not be able to alert others to this by himself. His wife, the key person in his care, could not undergo hospital training because of her advanced age. She received instruction on the techniques for the completion of IVH for one month from the visiting carer, but handling the syringe and needle and the clamp maneuver were difficult for her, and she later developed an infection and was hospitalized. Upon consultation with the primary physician, a change was made to a Groshong catheter, which reduced the maneuver burden, but the prepared checklist was not used and there were problems in the handling of the catheter and management during the period when the maneuvers were being carried out. In addition, discord arose in the family relations, so a grandchild who was a university student rather than the daughter-in-law received instruction according to the manual in order to care for the patient on the nurse's days off. Currently, HPN is being carried out 3/week with meal instructions adjusted to the patient's dysphagia and contact with the family on the nurse's days off. An issue remaining for the future is the use of informal resources in terms of both micro-intervention, including selection of a catheter with consideration of care ability and meal instruction matched to his eating function, and macro-intervention with consideration of the family environment and interpersonal relationships. Patient 2 was a 41-year-old woman with SLE. She was a former nurse, but self-care was not possible due to steroid myopathy.

In a public teaching hospital, all cases of NP in patients aged 65+ were ascertained by prospective surveillance during a 2-year period (n = 59). These elderly cases were compared with 59 cases of NP in patients aged 25 to 50 to describe differences in risk factors and outcomes. Elderly cases were then matched to elderly control subjects who were admitted to the same hospital service but did not develop NP.

We analyzed their clinical backgrounds on admission, the clinical course up to the terminal stage of the illness, and the outcome of patients who received artificial nutrition. In 95 patients, the main cause of the terminal illness was infection. The symptoms of these patients, such as cerebral infarction and cognitive dysfunction, deteriorated progressively, and eventually, eating became difficult. At this point, alternative methods for providing nutrition were discussed. For 60 patients (41 died of acute disease and 19, of advanced cancers), artificial nutrition was not considered. Artificial nutrition was administered to 63 patients; tube feeding was carried out in 30 patients. Because of repeated aspiration pneumonia, 14 of these 30 patients eventually underwent intravenous hyperalimentation (IVH). Thirty-three patients directly underwent IVH. Thirty-two patients did not undergo any feeding course. The mean survival times of the tube feeding and non-artificial nutrition groups were 827 and 60 days, respectively.

This review highlights the clinical features, diagnosis and treatment of the most common dermatoses of the male genitalia. Herpes genitalis and infections caused by human papillomavirus (HPV) are increasing, particularly in young sexually active people. Herpes simplex virus infection is the commonest infectious cause of genital ulceration, with evidence that many infections are asymptomatic. HPV infection may be latent, subclinical and clinical. The most common causal agents for condyloma acuminatum are low-risk HPV 6 and 11; high-risk HPV types 16 and 18 are associated with premalignant and malignant lesions. Treatment for genital warts remains unsatisfactory; recurrences are common. Imiquimod, a new topical immunotherapeutic agent, which induces interferon and other cytokines, has the potential to be a first-line therapy for genital warts. Scabies and pediculosis are transmitted by skin-to-skin contact and sexual transmission is common, with the penis and scrotum favourite locations for scabious lesions. Oral ivermectin, a highly active antiparasitic drug, is likely to be the treatment of choice, but until approval is granted it should be reserved for special forms of scabies. Common skin diseases, e.g. psoriasis and lichen planus, may have an atypical appearance in the genital area. The typical psoriatic scale is usually not apparent because of moisture and maceration. Allergic contact dermatitis of the genital area may result from condoms, lubricants, feminine hygiene deodorant spray and spermicides. More often, contact dermatitis is irritant, resulting from persistent moisture and maceration. Lichen sclerosus is a chronic inflammatory disease that occurs as atrophic white patches on the glans penis and foreskin. The penile form is a common cause of phimosis in uncircumcised men; involvement of the urethral meatus may lead to progressive meatal stenosis. Plasma cell balanitis is a benign, idiopathic condition presenting as a solitary, smooth, shiny, red-orange plaque of the glans and prepuce of a middle-aged to older man. Squamous cell carcinoma (SCC) in situ, e.g. erythroplasia of Queyrat and Bowen's disease, cannot be excluded clinically; their apparent clinical benignity may lead to lengthy periods of misdiagnosis and biopsy is required to confirm the diagnosis. SCC is the most common malignancy of the penis and the role of oncogenic HPV-types has been also established in SCC of the penis. Prevention of SCC of the penis presupposes an identification of risk factors, early detection of all pre-cancerous lesions and treatment of phimosis." }, { "id": "pubmed23n0665_6370", "title": "[Syphilis in the context of HIV-infection--a complex disease].", "score": 0.01436956081764825, "content": "A 39-year-old man complained about a slightly reddish non-itching rash evolving on his body during the last few weeks without any general symptoms.

Following informed consent, participants had a face-to-face interview and an examination to categorize foreskin status. HIV testing was conducted on site and relevant specimens collected for laboratory-based Herpes simplex type-2 (HSV-2), syphilis, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) testing. Overall, 1073 men were enrolled: 646 (60.2%) were uncut; 339 (31.6%) had a full dorsal longitudinal cut; 72 (6.7%) a partial dorsal longitudinal cut; and 14 (1.3%) were circumcised.

In this large cross-sectional study, men with a dorsal longitudinal foreskin cut were significantly less likely to have HIV, HSV-2 and syphilis compared with uncut men, despite still having a complete (albeit morphologically altered) foreskin. The protective effect of the dorsal cut suggests that the mechanism by which male circumcision works is not simply due to the removal of the inner foreskin and its more easily accessible HIV target cells. Exposure of the penile glans and inner foreskin appear to be key mechanisms by which male circumcision confers protection.Further research in this unique setting will help improve our understanding of the fundamental immunohistologic mechanisms by which male circumcision provides protection, and may lead to new biomedical prevention strategies at the mucosal level." }, { "id": "pubmed23n0517_199", "title": "Nine male cases of tinea genitalis.", "score": 0.009523809523809525, "content": "Nine cases of tinea genitalis observed in Siena and Terni (Italy) between 1988 and 2003 are reported because of their infrequency.

This patient had a positive progesterone test and her hormonal profile showed a maintained LH hypersecretion (&gt; 75 mUl/ml) which, joined to the presence of a hypophyseal microadenoma lead to suspect the presence of a gonadotrophin secreting tumor. The absence of LH response to TRH and its adequate suppression using oral contraceptives discarded this diagnosis. The histopathology of the excised ovarian tumor demonstrated that it is was a granulosa cell tumor. The physiopathological explanation of the case is based on the maintained levels of estrogens produced by the tumor that, through a positive feed-back mechanism similar to that of the polycystic ovary syndrome, produced a tonic LH elevation and GnRH hyper response. After the tumor excision, ovulatory cycles resumed and the patient became pregnant, facts that confirm the postulated hypothesis." }, { "id": "wiki20220301en203_18623", "title": "Functional hypothalamic amenorrhea", "score": 0.012333878079615182, "content": "In all cases of amenorrhea, pregnancy should be excluded.

The number of ovarian follicles is highly reduced already in infant and young MUL girls and the majority of them will have early depletion of follicles resulting in clinical and biochemical signs of POI. Both female and male patients with MUL show failure of sexual maturation, signs of hypogonadism and infertility. We studied the gonadal function, pubertal development and ovarian reserve in 33 MUL patients aged 5.1-47.3 years (median age 22.3) at the end of observation. The patients were followed between 2004 and 2014 and 19 pubertal or postpubertal patients were enrolled in a cross-sectional study. The period of postnatal activation of the hypothalamic-pituitary-gonadal axis (minipuberty), pubertal development and menstrual history were assessed longitudinally. The cross-sectional study included gynecological examination, analysis of reproductive hormones and ultrasonography with evaluation of ovarian volume and antral follicle count. Infant girls experienced a transient minipuberty with a high FSH surge. In childhood, gonadotropins were normal or slightly elevated but began to rise to hypergonadotropic levels in prepuberty. Anti-Müllerian hormone (AMH) levels remained undetectable or low throughout childhood. The onset of puberty occurred spontaneously and the median age at menarche was 12.5 years. Of the patients, 54% never attained regular menses and 10 years from menarche, only 8% of the women menstruated regularly. In the cross-sectional study, none of the patients had normal ovarian morphology under ultrasonography. Ovaries were hypoplastic and 82% had no or fewer than two visible antral follicles. AMH levels were undetectable in the vast majority (89%). The Finnish MUL patients genotypically form a homogenous group and therefore it is possible, that different TRIM37 mutations lead to different hypogonadal phenotypes. However, to date there is no known genotype-phenotype correlation in MUL. In MUL, AMH is a useful marker of ovarian function. MUL should be added to the list of syndromes associated with POI and correspondingly, TRIM37 should be added to the list of genes associated with POI. To our knowledge, TRIM37 is the first known gene coding for a peroxisomal membrane protein associated with female gonadal failure and infertility.

The mean GnRH in portal blood, as measured by radioimmunoassay, was 66 +/- 6.6 pg/ml (+/- SE) in 7 ovariectomized animals and 51 +/- 5.3 pg/ml (+/- SE) in 2 monkeys during the early follicular phase. Fluctuations in portal blood GnRH were most prominent in ovariectomized animals, with peak levels of 200-800 pg/ml and intervals of 1 to 3 hours between pulses. Peaks of GnRH during the early follicular phase did not exceed 200 pg/ml. The administration of estradiol (1000 ng, iv) to 3 monkeys did not decrease GnRH levels within the next 2 hours.

Menarche before the ninth birthday may serve as an additional criterion. Precocious puberty is divided in central precocious puberty and pseudoprecocious puberty. Central precocious puberty (GnRH dependent) occurs because of premature activation of hypothalamic-pituitary-gonadal axis and activity of gonadotrophins. Pseudoprecocious puberty (GnRH independent) is caused by activity of sexual steroids that are not the result of gonadotrophin activity. Objective of our study was to examine the etiology, clinical and laboratory manifestations of isosexual pseudoprecocious puberty in girls. In the period between 1995 and 2004, clinical and laboratory sings of 34 girls with precocious puberty were studied at the Endocrine Department of the Institute of Mother and Child Health Care of Serbia. Initial evaluations included height measurement, staging of puberty, bone age assessment and pelvic ultrasound. Important diagnostic sonographic parameters of precocious puberty were the volumes of ovaries and uterus as well as ovarian structure. The initial hormonal evaluation included measuring of plasma oestradiol, luteinizing hormone (LH) and follicle stimulating hormone (FSH). The luteinizing hormone releasing hormone (LHRH) stimulation test was used to evaluate LH and FSH responsiveness (60 microg/m2 LHRH-Relefact LHRH, Ferring). Blood samples were collected at 0, 20 and 60 minutes. Basal and GnRH stimulated LH and FSH were determined by immunoradiometric assay. Estradiol concentration was measured using the fluoroimmunometric assay. Thirty-four girls aged 6 months to 9 years (mean age 4.5 years) with precocious puberty were studied during the period of 9 years. Eleven girls presented with breast development, six with vaginal bleeding and seventeen with signs of puberty. On the basis of clinical signs, bone age, estradiol levels and LHRH test, premature thelarche was diagnosed in eleven patients (32.4%), premature menarche in six (17.6%) and central precocious puberty in ten girls (29.4%). Seven girls (20.6%) presented with pseudoprecocious puberty. Pelvic ultrasound examination revealed unilateral ovarian cysts in six patients and granulosa cell tumor in one. Elevated estrogen serum levels and failure of gonadotropin responses after gonadotropin releasing hormone were the classical findings in patients with isosexual pseudoprecocious puberty during the acute period of disease. In four patients, the cyst decreased spontaneously after several months, while in two patients, the cyst was removed by laparotomy. Surgical treatment was performed in a patient with granulosa cell tumor. Our work demonstrates that autonomous functional ovarian follicle cyst is the most often cause of isosexual pseudoprecocious puberty. Short period of observation is suggested because the cyst can resolve spontaneously. On the other hand, juvenile granulosa cell tumor, as highly malignant tumor, should be removed as soon as diagnosis is established." }, { "id": "pubmed23n0071_20358", "title": "[Ovarian stimulation for in vitro fertilization using LHRH agonists: comparison of plasma and intra-follicular hormone profiles using \"short\" and \"long\" protocols].", "score": 0.009009009009009009, "content": "Plasmatic estradiol (E2), progesterone (P) and LH were measured during the follicular phase of 343 cycles induced for in vitro fertilization (IVF) using a LHRH agonist in a \"long protocol\" (Group I) and 76 cycles in a \"short protocol\" (Group II).

Patients presenting with oligo- or amenorrhoea between 2002 and 2006 were selected, with the exclusion of women with WHO III oligoamenorrhoea, hyperprolactinaemia or with wrongly timed endocrine measurements. A total of 252 patients were included (198 oligo/amenorrhoeic PCOS patients and 54 oligo/amenorrhoeic controls).

In women the pituitary sensitivity varied in the menstrual cycle due to the typical cyclic variation of oestradiol and progesterone. The max delta LH increase to 100 mug LHRH was observed in the periovulatory period (183 +/- 41 mU/ml); it was also significantly higher in the luteal (49 +/- 7 mu/ml) than in the early follicular phase (18 +/- 3 mU/ml). The effect of exogenous sex steroid hormones taken as contraceptive drugs was then studied in 15 women. Significantly lower LH and FSH basal values as well as responses to LHRH were observed in 8 normal women under oral combined contraceptives. Conversely, in 7 women under oral sequential contraceptives, basal LH and FSH remained in the normal range. The LH-FSH responses were increased and delayed when these tests were performed during the period of estrogen treatment. Thus, with combined oral contraceptives, constant and high levels of estrogens and progesterone not only inhibit the LH peak, but also decrease the basal LH-FSH levels and responses to releasing hormone. Conversely, with sequential oral contraceptives, the low level of estradiol does not inhibit these responses and even enhances them. In menopausal women both basal and gonadotrophin responses to LHRH were increased indicating an important pituitary reserve. In menstruating women a significant estradiol increase is observed 2 and 4 hours after a 100 mug LHRH injection, both during the follicular and the luteal phases whereas progesterone increases only in the luteal phase. In men, testosterone was found to increase 4 hours after a 100 mug LHRH injection. These studies show that in normal subjects, sex steroid hormones are important regulators of the sensitivity of the pituitary responsiveness to releasing hormone." }, { "id": "pubmed23n0367_8089", "title": "Evolution of clinical symptoms in a young woman with a recurrent gonadotroph adenoma causing ovarian hyperstimulation.", "score": 0.008771929824561403, "content": "To demonstrate the clinical course in a young female with gonadotroph adenoma causing ovarian stimulation.

FSH, LH, beta-LH, inhibin A and B, estradiol, prolactin (PRL), and beta-chorionic gonadotrophin (beta-CG) were measured, and the responses of FSH, LH and beta-LH to thyrotrophin-releasing hormone (TRH) were documented.

Membranous nephropathy (MN) was the most common renal histological pattern (31%). Mesangial proliferative glomerulonephritis (GN) was found in 21% of cases (IgA nephropathy 12%, non-IgA GN 9%), minor changes in 17%, renal amyloidosis in 11%, interstitial nephritis in 9%, sclerotic GN in 4%, and crescentic GN in 2%. MN was relatively more frequent in men than in women, and most developed nephrotic syndrome, while a few developed renal failure. Disease-modifying antirheumatic drugs (DMARDs) correlated with MN in 26 of 31 cases. Mesangial proliferative GN showed high-grade hematuria. Amyloidosis correlated with long duration of RA; approximately half of the cases with amyloidosis also had nephrotic syndrome, and 82% developed renal failure. Of the 100 patients, 82% showed some tubulo-interstitial changes, which might be related to non-steroidal anti-inflammatory drugs. Because renal lesions in RA are very diverse, and early stage cases of MN and amyloidosis can be detected only by histological examinations, renal biopsy should be performed in cases with continuous urinary abnormalities or progressive renal failure.

A 58-year-old Caucasian male presented to the hospital experiencing malaise, fevers, decreased oral intake, nausea, and vomiting for one week duration. His past medical history consisted of newly diagnosed but untreated rheumatoid arthritis, hypertension, and non-insulin-dependent diabetes mellitus. He was found to have acute renal failure, proteinuria, and hypoglycemia. Standard therapy, including intravenous fluids, did not improve his acute renal failure. A vasculitis workup resulted in a positive myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA). Renal biopsy revealed crescentic glomerulonephritis (GN) pauci-immune type, suggestive of MPO-ANCA-associated vasculitis (MPO-AAV).

Persistent proteinuria was caused by drugs in 14 of 17 patients and disappeared in most cases. Risk factors for drug induced proteinuria included a raised C reactive protein and erythrocyte sedimentation rate and age over 50 at entry.

The incidence of haematuria at entry did not differ among patients who had been treated with non-steroidal anti-inflammatory drugs, disease modifying antirheumatic drugs, or no drugs. In some patients with isolated haematuria, the haematuria appeared when the activity of RA was high and resolved when it was low.

Most of them had degrees 2 and 3 PA (62.7 and 24.4%, respectively). Systemic manifestations were encountered in 60 (63.8%) patients. Eighty one patients took nonsteroidal antiinflammatory drugs (NSAID) continuously: 18 patients for a year, 32 for 5 years, 14 for 6 to 10 years, and 17 for over 10 years. All the patients underwent clinical, laboratory, and instrumental study of partial functions of the kidney. Immunological study involved solid-phase immunoassay of IgA and IgM rheumatoid factor, von Willebrand factor antigens (WF:Ag), C-reactive protein. The serum concentrations were measured by the Mancini method. Changes in urinalysis and/or signs of decreased glomerular and tubular functions were found in 69 (73.%) patients, 25 (26.6%) had arterial hypertension. Tubular dysfunctions were more common [31 (32.9%) patients]. Signs of early renal failure were detected in 20 (21.2%) patients. There were no cases of acute renal failure. Amyloidosis, glomerulonephritis, pyelonephritis were diagnosed in 5 (5.3%), 16 (17%), and 13 (13.8%) patients, respectively. The above renal lesions were concurrent in some patients. Renal lesion correlated with the progression and severity of RA, the presence of systemic manifestations, and age. There was no relationship of both 5- and 10-year use of NSAID to the symptoms of renal disease. The use of these drugs for over 10 years was concurrent with the signs of chronic renal failure and arterial hypertension. Analyzing immunological disorders showed an association of increased erythrocytic sedimentation rates and WF:Ag with amyloidosis, that of higher IgA concentrations with proteinuria and tubular dysfunctions. It is concluded that renal lesion is common in RA, there is a predominance of tubular interstitial changes. In rare cases nephropathy is characterized by a benign course and fails to result in uremia. The symptoms of renal diseases are largely associated with RA progression and severity and the patients' age. Prolonged continuous use of NSAID may contribute to the development of renal failure.

The scarcity of reports is due to the difficulties of pinpointing this subject; in fact a bloody investigation like kidney biopsy is necessary to obtain an exact diagnosis. Moreover it is often clinically hard to distinguish renal injury provoked by rheumatoid arthritis from nephropathy caused by drugs, either non steroidal antiinflammatory drugs or disease modifying antirheumatic drugs. This topic is perhaps neglected because primary renal involvement in rheumatoid arthritis is not considered to influence the survival, with the exception of renal amyloidosis. Pathologic examination of kidney biopsy shows in order of frequency: mesangial nephritis, renal amyloidosis, membranous nephritis, focal proliferative nephritis, minimal nephritis, interstitial nephritis. Both immune complexes and antineutrophil cytoplasmic antibodies may play a pathogenetic role. The mesangial nephritis with IgA or IgM deposits is linked to high levels of rheumatoid factor of IgA or IgM class; it has been hypothesized that the ability of mesangium to remove circulating immune complexes provokes the mesangial damage. Moreover it has been observed that rheumatoid arthritis with renal involvement shows positivity for perinuclear antineutrophil cytoplasmic antibodies more frequently than rheumatoid arthritis without nephropathy. Also in the former cases the title of these autoantibodies is higher. The aim of this paper is to bring the terms of the problem into focus by the revision of the literature.

These drugs, as well as RA itself, can cause kidney injury. RA may trigger mesangial proliferative glomeru- lonephritis (MesPGN), membranous nephropathy (N), thin basement membrane disease, and renal amyloi- dosis. As for anti-rheumatic drugs, non-steroidal anti-inflammatory drugs (NSAID) increase serum Cr lev- els due to a reduction of glomerular circulation, particularly in the presence of dehydration. Among disease- modifying anti-rheumatic drugs (DMARD), methotrexate as an anchor drug for RA rarely causes tubular ob- struction as a result of its crystallization, and bucillamine occasionally elicits IN. Calcineurin inhibitors induce vasoconstriction of the afferent arteries. Recently developed anti-rheumatic drugs, biologics, include biological inhibitors of TNF-a, IL6, and CD80/26. These can generally induce the remission of RA, while they have been reported to albeit uncom- monly trigger autoimmune renal disorders (AIRD). A recent meta-analysis identified a total of 29 cases with biologics-induced AIRD, 62% of who manifested AIRD within 12 months after treatment with biologics. AIRD cases were classified into 3 different groups: isolated autoimmune renal disorders (IARD, n =13), glo- merulonephritis with systemic vasculitis (GNSV, n= 12), and glomerulonephritis with lupus-like syndrome (GNLS, n=4). The IARD cases had 4 MesPGN, 4 MN, and 2 crescentic GN, while the GNSV cases had 8 crescentic GN and 3 purpura GN, and the GNLS cases had all MesPGN. To detect these renal disorders early in RA patients, urinalysis and serum Cr measurement should be peri- odically performed. New urinary biomarkers (L-FABP and Ngal) may be more sensitive for kidney injury. Notably, in RA patients receiving biologics, ANA, anti-dsDNA, and ANCA should also be tested at the base- line and regular intervals.

A mean 1,341 +/- 405 ml of blood were withdrawn so as to reach a mean haematocrit of 30.6 +/- 2.4%. NH was completed within 17 +/- 6 min. No major haemodynamic changes occurred during the procedure. No significant differences were observed between expected and observed final haematocrits. There was no effect of the volume of blood withdrawn on the error of haematocrit prediction (0.5 +/- 0.3%). However, a higher rate of blood removal could increase this error. This easy-to-use device seems to provide fast and identical rates of blood removal and replacement. The expected haematocrit may thus be reached reliably, even if this must be checked for the sake of safety." }, { "id": "pubmed23n0808_16878", "title": "Exchange transfusion can be life-saving in severe propanil poisoning: a case report.", "score": 0.009433962264150943, "content": "Propanil is an important cause of herbicide poisoning in Sri Lanka, accounting for about 2% of all cases of self-poisoning. The outcome is extremely poor when the poisoning is severe and current medical care is of limited efficacy. Death usually occurs due to the severe and prolonged methaemoglobinaemia. We describe a case of severe Propanil poisoning, successfully treated by exchange transfusion at a tertiary care hospital in Sri Lanka. A 17-year old Sri Lankan male (body weight--42 kg), presented to a local hospital 1 hour after self-ingestion of nearly 500 ml (4.3 g/kg) of liquid Propanil (concentration--360 g/l). On admission he had dizziness and peripheral cyanosis. He was given intravenous methylene blue (1 mg/kg) within one hour of admission, which was repeated subsequently due to minimal response. The next day morning, (18 hours after poisoning) the patient was transferred to the National Hospital of Sri Lanka (NHSL) for further management. On admission to NHSL, he was drowsy and confused, had a shallow respiratory effort and marked central and peripheral cyanosis. Respiratory rate was 20/min, with a pulse-oximetry of 77% on room air. The arterial blood gas analysis was as follows; pH--7.24, HCO3(-)--12 mmol/l, pCO2--28 mmHg, pO2--239 mmHg and O2 saturation--100%. Exchange transfusion was commenced within two hours of admission to NHSL. A dramatic improvement in oxygen saturation was observed immediately afterwards, with the saturation in pulse-oximetry rising to &gt;95%. The level of consciousness and respiratory effort also improved. He was discharged subsequently 8 days after the initial poisoning. Propanil has potential to produce severe life threatening clinical manifestations, despite categorization as a herbicide with low toxicity. In cases of severe poisoning, exchange transfusion may be life saving. Since methylene blue, intensive care and exchange transfusion facilities are also not readily available in local hospitals, which frequently encounter cases of severe Propanil poisoning, early transfer of patients to tertiary care hospitals should be considered. Exchange transfusion may be helpful even in late stages in patients with severe poisoning." }, { "id": "pubmed23n0043_996", "title": "[Critical hematocrit from the viewpoint of the clinician].", "score": 0.009433962264150943, "content": "The hazards of homologous blood transfusions have been controlled but not eliminated by modern blood banking methods. In addition to the possibility of transmission of infectious diseases, blood transfusion has been reported to induce immunosuppression and thereby impair the host resistance of surgical patients. Experimental and clinical research, particularly in cardiac surgery, have encouraged physicians to accept postoperative anemia. The influence of hemodilution on oxygen supply to the tissues was found to be an increase of local oxygen tension. When hematocrit is progressively lowered under normovolemic conditions, blood cell flux per time and tissue unit is maintained at a hematocrit level as low as 20 vol% as a result of an increase of red blood cell velocity. An increasing number of cardiac operations have been performed upon patients belonging to Jehova's witnesses, inducing an average hematocrit of 11 vol% during extracorporeal circulation. The outcome of these patients was similar to that of patients having received blood transfusion in order to elevate oxygen supply. Some recent studies in critically ill patients demonstrate the importance of oxygen consumption as an important criterion in estimating the effect of oxygen transport. It seems to be proven that, in presence of cardiovascular stability, elevation of the hemoglobin level above 9 g/dl does not result in an increase of oxygen utilization. In accordance with the topical literature we suggest that during the perioperative period a hemoglobin level of 8.5 g/dl will become an accepted transfusion trigger.

This relationship persisted on multivariable analysis that adjusted for institution, age, and shock index with good discrimination (Area under the Receiver Operating Characteristic, 0.84). Shock index was also strongly associated with transfusion. Almost half of pediatric trauma patients with elevated shock index require transfusion following two crystalloid boluses and the odds of requiring a transfusion plateau at this point in resuscitation.

In our case, the reaction could be either anaphylaxis or anaphylactoid, but the latter seems more likely given the history of absence of prior sensitization. Other components of the drug, such as solvent, also need to be considered as a cause of this reaction. Considering all of the existing evidence, we need to be more cautious while using ondansetron and also to be aware of the various unusual side effects, especially when used in an out-of-hospital set-up.Our case report underscores the importance of physicians judiciously using the drug, particularly in the outpatient setting so as to reduce the incidence of avoidable adverse drug reactions." }, { "id": "pubmed23n0388_1051", "title": "[Parkinsonism probably induced by manganese].", "score": 0.00980392156862745, "content": "In all cases of young persons with clinical Parkinson s disease it should be suspected that it is secondary to some primary disorder.

The list of drugs able to induce parkinsonism is long and probably incomplete, because new drugs, with previously unknown antidopaminergic activity, are constantly being added. Not all the drugs have the same potency for inducing parkinsonism. We classify these drugs in three groups: (1) drugs with obvious antidopaminergic activity which regularly induce parkinsonism; (2) drugs able to induce parkinsonism in particular individuals and (3) drugs which may aggravate Parkinson's disease treated with levodopa. The reports of isolated cases of parkinsonism induced by widely-used drugs (drugs in group 2) may be the result of either an idiosyncratic side effect or a misdiagnosis of parkinsonism. The antidopaminergic activity of the drugs of this group is weak and not sufficiently demonstrated. Maybe, in these cases, the blockage of other neurotransmitters different from dopamine plays a role in the induction of parkinsonism. Probably, the number of patients with DIP is higher than reported or detected, because many patients suffer from weak symptoms that quickly disappear after drug withdrawal.

Generally speaking there is always an insistence on the need to conduct a thyroidal hormone study in any patient with symptoms of Parkinson, but no emphasis is put on the need to continue to rule out dysthyroidism throughout the natural course of the disease, in spite of the fact that the concurrence of both pathological conditions can be high and that, in the same way hypothyroidism can simulate Parkinson s disease, the latter can also conceal hypothyroidism. We report the case of a female patient who had been suffering from Parkinson s disease for 17 years and started to present on off fluctuations that did not respond to therapy. Hypothyroidism was observed and the hormone replacement therapy used to resolve the problem allowed the Parkinsonian fluctuations to be controlled.

TRPs and drugs most commonly implicated with TRPs were assessed for patients recruited from outpatient clinics in five major hospitals in Jordan using a standardized and validated pharmaceutical care manual. Drugs associated with different types of TRPs. Ultimately, 2,747 patients, with a total of 10,672 TRPs, were included in the study. The medication groups most commonly associated with TRPs were cardiovascular (53.0%), endocrine (18.1%), and gastrointestinal (7.7%) drugs. The most common specific drugs associated with TRPs from any category were atorvastatin (12.5%), metformin (8.5%), simvastatin (6.2%), and enalapril (5.9%). Cardiovascular medications were the most common drugs implicated with multiple subtypes of TRPs - most commonly, allergic reaction or undesirable effect (88.5%), drug product not available (87.3%), safety interaction issues (81.8%), a need for additional or more frequent monitoring (78.0%), and more effective drugs available (77.2%). Hypertension, diabetes mellitus, and dyslipidemia were the most common diseases associated with different subtypes of TRPs. The present study identified high-risk drugs for TRPs, which can be used as identification of targeting approach TRPs. Such an approach would improve care provided to patients and can inform health care policies." }, { "id": "pubmed23n1122_17094", "title": "Parkinson's disease, treatment choice and survival over time.", "score": 0.008849557522123894, "content": "We compared Monoamine oxidase B (MAO-B) - and dopamine agonist (DA) monotherapy patients with respect to survival, considering gender, age, first prescriber's specialty and relevant co-morbidity, and compared their specialist health care contacts and hospitalizations.

According to her husband, RS was diagnosed with stage IIIA large cell lung cancer 8 months earlier and was treated with concurrent chemotherapy (carboplatin, pemetrexed, and bevacizumab) and radiation therapy that was completed 4 months prior to admission. No other specific information about her treatment or outside health records was available. According to her husband, RS had been in her usual state of health until approximately 3 weeks prior, when she began having significant mental status changes. She first exhibited some difficulty finding words and later was noted to be putting food in a coffee maker. This spontaneously resolved after approximately 1 week; however, she rapidly developed slurred speech and began to make nonsensical statements. These manifestations also slowly improved but were followed by worsening speech deficit, difficulty walking, and impaired balance. During one of these episodes, she had an occurrence of incontinence. Her husband also noted an incident where her \"eyes were beating back and forth and the left side of her face was twitching.\" RS also had periods (according to her husband) where she \"did not seem to be interacting with her environment.\" These progressively worsened during the last week, and she completely stopped walking and talking 2 days prior to coming to the ED. According to her husband, RS had rheumatoid arthritis and no surgical history. Her family history was unknown except that RS's mother had \"seizures.\" RS had reportedly not used tobacco, alcohol, or drugs, and she was sexually active with her husband. Home medications included transdermal fentanyl 12 μg/hr patch changed every 72 hours; oxycodone-acetaminophen tablets 5-325 mg, two every 4 hours as needed for pain; prednisone 10 mg, one tablet daily; and megestrol 40 mg/mL suspension, 20 mL once daily for appetite stimulation. RS was admitted to an inpatient medical oncology service and evaluated by the oncology advanced practitioner (AP) on her second inpatient day. Upon exam, RS was nonverbal except for moaning in response to painful stimuli and to her sister's voice. Her vital signs were normal. She appeared ill but well-nourished, and she was mildly diaphoretic. Neurologic examination revealed that her pupils were slightly sluggish but equal, round, and reactive to light. Extraocular muscle movements were intact, but she did not move her eyes in response to commands. She tracked the AP and family members around the room with her eyes. Cranial nerve examination was intact with the exception of cranial nerves IX, X, and XI, which were difficult to examine given her inability to cooperate and open her mouth. Motor examination revealed increased tone throughout and intermittent, inconsistent resistance to passive movement. She was seen to move all four extremities spontaneously although not in response to commands. Deep tendon reflexes were intact and equal in all extremities. Examination of other body systems was as follows: there was dry, peeling skin on her lips, but her mucous membranes were moist and free of erythema or lesions. Her lungs were clear to auscultation bilaterally. Her heart rate and rhythm were regular, there were no murmurs, rubs, or gallops, and distal pulses were intact. Her abdomen was nondistended with normally active bowel sounds in all four quadrants. Her abdomen was soft, nontender to palpation, and without palpable masses. There was no peripheral discoloration, temperature changes, or edema, and examination of her skin was benign. <bWorkup</b On admission to the emergency department, serum laboratory studies were unrevealing for any potential causes of encephalopathy. Kidney and liver function were normal, making diagnoses of uremic and hepatic encephalopathies less likely. Cultures of the urine and blood were negative. Samples of cerebrospinal fluid (CSF) were obtained via lumbar puncture and were unrevealing for any abnormalities. Computed tomography (CT) of the head without contrast was negative for any acute intracranial process. Ultrasound of the right upper quadrant revealed a single, nonspecific, hypoechoic hepatic lesion. Computed tomography scans of the chest, abdomen, and pelvis demonstrated the primary malignancy in the upper lobe of the left lung, as well as possible metastatic disease within the left lung, right lung, and liver, and widespread osseous metastatic disease. Magnetic resonance imaging (MRI) of the brain performed 1 day after admission demonstrated numerous scattered punctate foci of enhancement throughout the supratentorial and infratentorial brain parenchyma, measuring at most 3 to 4 millimeters in diameter. There was no significant mass effect or midline shift. A paraneoplastic panel was sent to an outside laboratory and returned positive for antivoltage-gated potassium channel (VGKC) autoantibodies. <bDifferential Diagnosis</b Clinically, RS was exhibiting signs of encephalopathy, a broad term that indicates general brain dysfunction, the hallmark of which is altered mental status. Diagnosing encephalopathy is challenging, as many differential diagnoses must be considered. The clinician must consider metabolic derangements, toxic and infectious etiologies, psychiatric disorders, and less commonly, prion disorders and progressive dementia. Cultures of RS's blood and urine as well as other specialized endocrine tests were negative, decreasing the likelihood of a metabolic or infectious cause for her presentation. The abnormalities on her brain MRI were reviewed by a neuro-oncology team, who felt that the faint, nondescript nature of the visualized lesions was not suspicious for metastatic disease. Sequelae of seizures was also considered by neuro-oncology but dismissed given a grossly normal prolonged electroencephalogram. Some encephalopathies are caused by autoimmune or inflammatory mechanisms, which are confirmed by the presence of autoantibody markers and/or clear response to immunomodulatory treatment (Vernino, Geschwind, &amp; Boeve, 2007). These types of encephalopathies have been seen in patients with cancer and have thus been termed paraneoplastic. The presence of anti-VGKC antibodies on RS's paraneoplastic panel directed the inpatient medical oncology team toward a paraneoplastic neurologic disorder (PND) as the most likely diagnosis." }, { "id": "pubmed23n1111_11183", "title": "A Case of Steroid-Associated Expressive Aphasia.", "score": 0.009900990099009901, "content": "Expressive aphasia (non-fluent aphasia) is characterized by the inability to produce words or sentences.

However, NPSLE involving the medulla oblongata and spinal cord which presents as the \"owl's eye\" sign has to our best knowledge not been reported to date. A 19-year-old girl presented at our hospital with a 7-day history of fever and headache since a one day's exertion, accompanied by 2 days of weakness. The patient had slurred speech. Neurological examination revealed the presence of horizontal nystagmus and a limitation of bilateral eye movement when looking up and down. At the same time, she showed difficulty in raising the jaw, accompanied by a weak pharyngeal reflex. Muscle strength was remarkably decreased in all four extremities: the MRCS grade of the upper limbs was 4/5, while in the lower limbs it was 0/5. Hypotonia was apparent in the lower extremities. Regarding subjective sensation, the patient appeared to be experiencing an increased sense of pain in the whole body, and especially in the cervical region, abdomen, and feet. An examination of shallow reflex documented the reinforcement of the abdominal reflex. Deep tendon reflexes were symmetric: absent in lower, normal in upper extremities. The patient also had a stiff neck with a positive Kernig's sign. The laboratory examination showed elevated C - reactive protein and rheumatoid factor, as well as complement components 3 and 4. Symptomatic treatments were applied, but she did not respond well, after which we did immunological laboratory examinations. The results showed the presence of anti-nRNP/Sm, anti-dsDNA and anti-AMA M2 antibodies.

A 30-year-old woman presented to our Department with persistent, asymptomatic face edema and erythema lasting for 18 months. She was previously treated for rosacea with doxycycline (100 mg/day for four months) without improvement. Dermatological examination revealed erythematous, nonpitting, solid edema located on the mid-forehead, nose, and cheeks with sparse erythematous papules and pustules on the entire face including the chin and comedones, papules, and pustules on the back (Figure 1 and Figure 2). She was otherwise healthy and was not taking any medication. Laboratory tests with immunological tests and Quantiferon test together with MRI of the orbits, chest X-ray, chest high-resolution computed tomography, cranial X-ray, and abdominal ultrasound were all within normal limits. Histopathology revealed dermal edema, perivascular and peri-adnexal lymphohistiocytic infiltrate, and sebaceous gland hyperplasia. Based on the typical clinical picture, histopathological findings, and the exclusion of several differentials the diagnosis of MD was established. The patient was treated with oral isotretinoin (20 mg/day for eight months) without regression of solid edema and erythema on the face but with complete regression of acne on the trunk. She was started on oral corticosteroids (prednisolone, 20 mg/day for two months followed by reduction of the dose over three months), again with only slight short transient improvement and rapid relapse of facial erythema and edema. The patient refused any other suggested treatment. We treated our patient for a total 2 years and followed up for 5 years. The pathogenesis of MD is still unknown. It is considered a clinical variety or a complication of rosacea or acne which does not tend to regress spontaneously. It is believed that chronic inflammation in patients with MD is due to acne or rosacea causing structural damage to blood and lymph vessels (1,3,4). However, cases of MD without previous history of rosacea and acne have been reported supporting the distinct disease theory (3,4). Edema and erythema are localized on the upper half of the face affecting the forehead, glabella, eyelids, nose, and cheeks. Although the symptoms may come and go, MD usually does not improve without treatment (5). Several therapeutic options have been reported, although there is no established standard treatment for MD. Reported therapy includes short-term oral isotretinoin (0.5 mg/kg/day), long-term oral isotretinoin (40-80 mg/day, 10-24 months), long-term doxycycline, combination of systemic corticosteroids and antibiotic (prednisolone 20 mg/day for 2 weeks and doxycycline 200 mg/day for 12 weeks), slow-releasing doxycycline monohydrate (40 mg/day for 6 months), long-term minocycline (50 mg/day for 4 months), and a combination of both oral retinoid and ketotifen (isotretinoin 0.7 mg/kg/day for 4 months, ketotifen 2 mg/day for 4 months) (1,2,6,8).

Unfortunately, there was a recurrence of her infection requiring a second irrigation and debridement 1 month after index procedure. At final follow-up, the patient had complete neurologic recovery. Case 2: A 38-year-old G10P0 presented at 36-week gestation in labor with LE weakness and difficulty ambulating. After delivery, she had significant LE neurologic deficits. MRI demonstrated thoracic osteodiscitis with associated epidural abscess. She underwent thoracic laminectomy and fusion (T7-12), abscess decompression, and antibiotic therapy. Unfortunately, despite aggressive treatment, she has persistent LE neurologic deficits. Pregnancy complicates the diagnosis and treatment strategies of SEA: back pain is very commonly underestimated, especially in the absence of fever and gross neurologic deficits. Prompt diagnosis and treatment are paramount to prevent neurologic decline and facilitate recovery. It is important to perform a focused physical exam noting motor strength, sensation, and reflexes. Coordinated management between the Emergency Department, OB-GYN, and spinal surgery team is required for best possible patient outcomes. Typically, management consists of aggressive surgical decompression and antibiotic therapy." }, { "id": "pubmed23n0364_22126", "title": "[A case of ipsilateral ageusia, sensorineural hearing loss and facial sensorimotor disturbance due to pontine lesion].", "score": 0.009345794392523364, "content": "We report a 58-year-old woman with pontine lesion presented with subacute onset of unilateral gustatory disturbance accompanied by facial numbness, and hearing loss.

The disorder is included under anxiety disorders because it shares some obsessive-compulsive features. Patients have the tendency towards feelings of unattractiveness, body dissatisfaction, and low self-esteem (1,2). It is a major psychiatric problem, but many patients with this disorder first present to a dermatologist. An 11-year-old girl came to our department with a 2-month history of diffuse hair loss on the frontoparietal and parietotemporal area (Figure 1). She had originally been examined by a pediatrician with the diagnosis of alopecia areata. The patient`s personal history included hay fever and shortsightedness, and she suffered from varicella and mononucleosis. Nobody in the family history suffered from alopecia areata, but her father has male androgenetic alopecia (Norwood/Hamilton MAGA C3F3). The mother noticed that the child had had changeable mood for about 2 months and did not want to communicate with other persons in the family. The family did not have any pet at home. At school, her favorite subjects were Math and Computer Studies. She did not like Physical Education and did not participate in any sport activities during her free time. This was very strange because she was obese (body-mass index (BMI) 24.69). She was sometimes angry with her 13-year-old sister who had better results at school. The girl had suddenly started to wear a blue scarf. The parents did not notice that she pulled out her hair at home. Dermatological examination of the capillitium found a zone of incomplete alopecia in the frontoparietal and parietotemporal area, without inflammation, desquamation, and scaring. Hairs were of variable length (Figure 1). There was a patch of incomplete alopecia above the forehead between two stripes of hair of variable length (Figure 2). The hair pull test was negative along the edges of the alopecia. Mycological examination from the skin capillitium was negative. The trichoscopy and skin biopsy of the parietotemporal region of the capillitium (Figure 3) confirmed trichotillomania. Laboratory tests (blood count, iron, ferritin, transferrin, selenium, zinc, vitamin B12, folic acid, serology and hormones of thyroid gland) were negative. We referred the girl for ophthalmologic and psychological examination. Ophthalmologic examination proved that there was no need to add any more diopters. The psychological examination provided us with a picture in which she drew her family (Figure 4). The strongest authority in the family was the mother because she looked after the girls for most of the day. She was in the first place in the picture. The father had longer working hours and spent more time outside the home. He worked as a long vehicle driver. He was in the second place in the picture. There was sibling rivalry between the girls, but the parents did not notice this problem and preferred the older daughter. She was successful at school and was prettier (slim, higher, curly brown hair, without spectacles). Our 11-years-old patient noticed all these differences between them, but at her level of mental development was not able to cope with this problem. She wanted to be her sister's equal. The sister is drawn in the picture in the third place next to father, while the patient's own figure was drawn larger and slim even though she was obese. Notably, all three female figures had very nice long brown hair. It seemed that the mother and our patient had better quality of hair and more intense color than the sister in the drawing. The only hairless person in the picture was the father. The girl did not want to talk about her problems and feelings at home. Then it was confirmed that our patient was very sensitive, anxious, willful, and withdrawn. She was interested in her body and very perceptive of her physical appearance. From the psychological point of view, the parents started to pay more interest to their younger daughter and tried to understand and help her. After consultation with the psychiatrist, we did not start psychopharmacologic therapy for trichotillomania; instead, we started treatment with cognitive behavioral therapy, mild shampoo, mild topical steroids (e.g. hydrocortisone butyrate 0.1%) in solution and methionine in capsules. With parents' cooperation, the treatment was successful. The name trichotillomania was first employed by the French dermatologist Francois Henri Hallopeau in 1889, who described a young man pulling his hair out in tufts (3-5). The word is derived from the Greek thrix (hair), tillein (to pull), and mania (madness) (5). The prevalence of TTM in the general adult population ranges from 0.6% to 4%, and 2-4% of the general psychiatric outpatient population meet the criteria for TTM (2-5). The prevalence among children and adolescents has been estimated at less than 1% (5). The disease can occur at any age and in any sex. The age of onset of hair pulling is significantly later for men than for women (3). There are three subsets of age: preschool children, preadolescents to young adults, and adults. The mean age of onset is pre-pubertal. It ranges from 8 to 13 years (on average 11.3 years) (2-5). The occurrence of hair-pulling in the first year of life is a rare event, probably comprising &lt;1% of cases (5). The etiology of TTM is complex and may be triggered by a psychosocial stressor within the family, such as separation from an attachment figure, hospitalization of the child or parent, birth of a younger sibling, sibling rivalry, moving to a new house, or problems with school performance. It has been hypothesized that the habit may begin with \"playing\" with the hair, with later chronic pulling resulting in obvious hair loss (2). Environment is a factor because children usually pull their hair when alone and in relaxed surroundings. The bedroom, bathroom, or family room are \"high-risk\" situations for hair-pulling (5). Men and women also differed in terms of the hair pulling site (men pull hair from the stomach/back and the moustache/beard areas, while women pull from the scalp) (3). Pulling hair from siblings, pets, dolls, and stuffed animals has also been documented, often occurring in the same pattern as in the patient (5). Genetic factors contributing to the development of TTM are mutations of the SLITRK1 gene, which plays a role in cortex development and neuronal growth. The protein SAPAP3 has been present in 4.2% of TTM cases and patients with obsessive-compulsive disorder (OCD). It may be involved in the development of the spectrum of OCD. A significantly different concordance rate for TTM was found in monozygotic (38.1%) compared with dizygotic (0%) twins in 34 pairs (3). The core diagnostic feature is the repetitive pulling of hairs from one`s own body, resulting in hair loss. The targeted hair is mostly on the scalp (75%), but may also be from the eyebrows (42%), eyelashes (53%), beard (10%), and pubic area (17%) (3,5). There are three subtypes of hair pulling - early onset, automatic, and focused. Diagnostic criteria for TTM according to DSM-IV criteria are (2,3,5): 1) recurrent pulling of one`s hair resulting in noticeable hair loss; 2) an increasing sense of tension immediately prior to pulling out the hair or when attempting to resist the behavior; 3) pleasure, gratification, or relief when pulling out the hair; 4) the disturbance is not better accounted for by another mental disorder and is not due to a general medical condition (e.g., a dermatologic condition); 5) the disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning. The differential diagnosis includes alopecia areata (Table 1) (6), tinea capitis, telogen effluvium, secondary syphilis, traction alopecia, loose anagen syndrome, lichen planopilaris, alopecia mucinosa, and scleroderma (2-5). Biopsy of an involved area (ideally from a recent site of hair loss) can help to confirm the diagnosis (5). On histologic examination, there are typically increased numbers of catagen and telogen hairs without evidence of inflammation. Chronic hair pulling induces a catagen phase, and more hairs will be telogen hairs. Pigment casts and empty anagen follicles are often seen. Perifollicular hemorrhage near the hair bulb is an indicator of TTM (2). Complications of TTM are rare, but they comprise secondary bacterial infections with regional lymphadenopathy as a result of picking and scratching at the scalp. Many patients play with and ingest the pulled hairs (e.g. touching the hair to lips, biting, and chewing). Trichophagia (ingestion of the hair) can lead to a rare complication named trichobezoar (a \"hair ball\" in stomach). This habit is present in approximately 5% to 30% of adult patients, but it is less frequent in children. Patient with trichophagia present with pallor, nausea, vomiting, anorexia, and weight loss. Radiologic examination and gastroscopy should not be delayed (2,4,5). The management of the disease is difficult and requires strong cooperation between the physician, patient, and parents. The dermatologist cannot take part in the therapy, strictly speaking, but without the psychological, psychopharmacologic, and topic dermatologic treatment a vicious circle will be perpetuated.

Simultaneous involvement of the oral mucosa is extremely rare, but it may be the only affected area (2). A 55-year-old woman was referred to the Department of Oral Medicine, School of Dental Medicine University of Zagreb due to whitish lesions on the right ventrolateral part of the tongue and buccal mucosa with desquamative gingivitis (Figure 1, a-c). The lesions were asymptomatic but indurated on palpation. Histology was conclusive for oral lichen sclerosus (OLS). The lesions on gingiva were successfully treated with betamethasone ointment, three times a day for two weeks. One year earlier, she had been referred to the Department of Dermatology and Venereology with progressive pruritus and dyspareunia, white patches, obliteration of the labia minora, and stenosis of the introitus (Figure 2). Histology was conclusive for vulvar LS (Figure 3, a and b). She was successfully treated for 5 months with clobetasol propionate 0.05% ointment. The patient was taking levothyroxine to treat hypothyroidism associated with Hashimoto's thyroiditis and was otherwise healthy. Oral LS is clinically characterized by the appearance of white macules, papules, or plaques mostly appearing on labial mucosa but also on buccal, palate mucosa and on the lower lip (2,3). On the genitals, it typically manifests as atrophic white plaques, which may be accompanied by purpura or fissuring (1). While vulvar LS is often associated with pruritus, dyspareunia, and dysuria, OLS is often asymptomatic, although pain, soreness, pruritus, and tightness when opening the mouth can be present (1,2). Oral manifestations of LS, as well as association of anogenital and oral LS, are rarely reported in the literature (4-6). Tomo et al. searched the Medline database for papers reporting oral LS cases with histological diagnosis confirmation from 1957 to 2016 and found only 34 cases of oral LS with histopathologic confirmation of the diagnosis (4). Kakko et al. reported 39 histologically proven cases of OLS (2). Attilli et al. (5) reviewed the clinical and histologic features of 72 cases of LS with oral/genital involvement. They reported that LS was diagnosed with exclusive genital lesions in 45, exclusive lip involvement in 20, and orogenital involvement in only 7 cases (5). Some believe that many cases of clinically diagnosed lichen planus may actually be LS and that isolated oral mucosal LS may not be as rare as is generally thought (2). While vulvar LS can occur at any age with increasing incidence with age, the median age of patients with OLS was 34 years and most of the patients were female (1,2,5). Due to the small number of patients in the literature, treatment recommendations for OLS are not available. In case of symptomatic oral lesions, topical or intralesional corticosteroids are considered to be the first-line treatment (2). First-line treatment for anogenital LS is a potent to very potent topical corticosteroid ointment, and second-line therapies include topical calcineurin inhibitors 1% pimecrolimus and 0.1% and 0.03% tacrolimus (1). For treatment-resistant genital LS, oral retinoids, methotrexate, and possibly local steroid injections for single lesions are mainly applicable for women (1). There is limited evidence for systemic treatments for both conditions. If it is not treated, genital LS is associated with a greater degree of scarring and an elevated risk of progression to squamous cell cancer; however, malignant transformation of OLS has not been reported (1-6).

A 35-year-old healthy, non-comorbid man from rural India came to the outpatient department with complaints of persistent tingling, numbness, and weakness of both lower limbs (right more than left) for 10 days. The clinical picture showed acute-onset urinary retention, which was relieved by urinary catheterization. An indigenous medical practitioner had prescribed drugs to treat a urinary tract infection. His weakness gradually progressed over the following week, causing him to become bedridden. During the removal of the catheter, he felt urgency, increased frequency of micturition, and overt urinary incontinence. He gave no history suggestive of any girdle-like sensations, root/radicular/tract pain, vertebral pain, trauma, recent vaccination, and diarrheal or febrile illness. For the last 8 months, he had a complaint of an insidious-onset, persistent, bilateral, dull aching pain in the gluteal region accompanied by low-back pain and morning stiffness up to 1 h, which markedly improved with activity and reoccurred following long periods of inactivity. He sometimes had to rise in the middle of the night because of excruciating pain, which could be relieved after moving around the room and corridors for half an hour. He was taking over-the-counter diclofenac tablets for pain relief prescribed by some indigenous medical practitioners who told him that it was due to overwork in agricultural fields, that is, mechanical back pain. He also had a normal X-ray of the lumbosacral spine. He had no addiction liabilities, and none of the family members had ever suffered from a similar kind of illness. He had never consulted any trained medical practitioner, as his previous back-pain-related symptoms responded well to the tablets prescribed by the indigenous medical practitioner(s). During examination, he was found to have recent-onset, asymmetric spastic paraparesis (right more than left) with upper motor neuron-type urinary bladder symptoms. Cognitive assessment (assessed by the Montreal cognitive assessment test) was normal, and posterior column sensations were preserved. Sensory system examination revealed no definite sensory level. Except for the paretic lower limbs, cerebellar functions were normal in other regions. Neuro-ophthalmological examinations were also normal, and no signs of meningeal irritation were observed. The history and course of the disease and clinical examinations were analyzed. Selective tractopathy (early and predominant motor and autonomic tract affection) was suggested for an intramedullary demyelinating pathology affecting the anterior central cord. This case was initially classified as acute-onset non-compressive myelopathy at the lower cervical/upper dorsal region level in a patient with a pre-existing axial spondyloarthropathy. Complete blood cell count; liver, kidney, and thyroid function tests; and plasma glucose and electrolytes were normal, except for an increased erythrocyte sedimentation rate (66 mm in the first hour). Magnetic resonance imaging (MRI) of the spinal cord revealed a demyelinating LETM from C5 to D4 level (Figure 1). Meanwhile, an MRI of the sacroiliac joints revealed bilateral sacroiliitis. Brain and orbital MRIs were devoid of any lesions. Anti-aquaporin 4 (AQP-4) antibodies were tested by cell-based assay in serum and cerebrospinal fluid (CSF), and both were positive. CSF further revealed lymphocytic pleocytosis and increased intrathecal protein production. Visually evoked potential recordings were also normal. In addition, anti-myelin oligodendrocyte glycoprotein antibodies were negative. Anti-nuclear antibody (ANA), ANA-profile, autoimmune vasculitis profile (c-ANCA, p-ANCA), neurovirus panel (i.e., polymerase chain reaction for adenovirus, Epstein-Barr virus, herpes simplex viruses 1 and 2, human herpesviruses 6 and 7, cytomegalovirus, enteroviruses, varicella-zoster virus, Japanese encephalitis, and dengue virus), CSF-polymerase chain reaction for <iMycobacterium tuberculosis</i, angiotensin-converting enzyme, anti-phospholipid, and anti-thyroid antibodies were negative. Anti-CCP-antibody and rheumatoid factor were also negative, including creatine phosphokinase level and serum vitamin B12. Moreover, serologies for hepatitis B, C, human immunodeficiency virus, and scrub typhus were negative. However, HLA-B27 assay was positive. The final diagnosis was AQP4-positive NMOSD associated with AS. He was placed on pulse intravenous methylprednisolone (1 g/day for 5 days). Consequently, his lower limb power improved remarkably. Cyclical rituximab therapy was initiated to prevent relapses. At 3-month follow-up, he had no residual neurological deficit except for persistence of paresthesias. Neuroimaging and visually evoked potential studies revealed no active or new lesions. After 6 months of therapy, a subjective and objective improvement was observed in disease severity based on the Ankylosing Spondylitis Disease Activity Score.

Recent evidence has shown T-cell-mediated inflammatory responses in cases of NMOSD.<sup20</sup In particular, Th17 and Th2-related cytokines are elevated in the CSF of NMO patients.<sup20</sup Environmental factors such as <iEscherichia coli</i have also been proven to aggravate autoimmunity in AS and NMOSD (however, body fluid cultures for <iEscherichia coli</i, performed in our patient, showed similar association, and they were found negative two times).<sup21,22</sup Although large-scale epidemiological studies investigating the underlying pathogenesis related to these diseases are lacking, studies have demonstrated an increased incidence of optic neuritis among patients with AS.<sup23</sup Systemic sclerosis and mixed and undifferentiated connective tissue diseases were excluded after expert opinions (from two board-certified rheumatologists and two dermatologists) because of the lack of suggestive clinical findings (e.g., absence of skin thickening, salt-and-pepper appearance, nail changes, Mauskopf facies, sclerodactyly, calcinosis cutis, Raynaud's phenomenon, other cutaneous manifestations, pulmonary arterial hypertension/interstitial lung disease, dysphagia, muscular pain/weakness renal impairments, absence of ANA, anti-centromere antibodies, anti-Scl-70, PM-Scl antibodies, anti-ds DNA, PCNA, CENP-B, anti-nucleosomes, anti-Smith, anti-U1-RNP, anti-Jo1, anti-Mi2, anti-Ro52, anti-La antibodies, and normal C3 and C4 complement levels) (The European League Against Rheumatism and the American College of Rheumatology classification criteria 2019).<sup24</sup Finally, our patient was treated with intravenous steroids followed by rituximab infusions, a monoclonal anti-CD20 antibody directed against B-cells. In particular, this patient clinically and radiologically responded to immunomodulatory drugs, which might support a possible common pathogenic basis of the two processes. TNF-alpha inhibitors are commonly used as novel therapeutics in AS; however, they can potentially result in serious complications, that is, secondary demyelinating disorders.<sup25</sup However, such inhibitors in this patient were not used. When used in cases of AS, they show satisfactory results.<sup25,26</sup Therefore, it was decided to treat him with rituximab only without adding any second immunomodulatory. Other possible therapeutic options include cyclophosphamide and mycophenolate mofetil, but they were not used because of their low efficacy-safety balance. Moreover, plasmapheresis was not available in our specific setting, despite solid evidence that early treatment with therapeutic strategy (5-7 courses) provides good long-term outcomes in patients with NMOSD.<sup27</sup Therefore, when dealing with a case of acute non-compressive myelopathy, history and clinical examination are important to determine the potential underlying etiology and identify an undermined systemic disorder with apparently unrelated non-specific features. Connective tissue disorders should always be considered as a differential diagnosis and be ruled out in all cases of either seropositive or seronegative NMOSD. A diagnosis of AS should be considered in relevant circumstances when dealing with a case of isolated seronegative LETM. Moreover, early diagnosis and treatment of AS are quintessential to prevent lifelong distressing disabilities. However, whether patients with AS have any extra predilection to develop NMOSD throughout their life requires further studies." } ] } } }

The disease occurs in people over the age of 50 years and reaches a peak at 72 years old. Women are affected twice as often as men. The prevalence is estimated to be 0.3-0.7% in the Caucasian population over 50 years old. Misdiagnosis of PMR is common. The differential diagnosis primarily includes impingement syndrome, osteoarthritis of the shoulders, calcifying tendinitis of the rotator cuff, bursitis, omarthritis or inflammatory rheumatic diseases, such as rheumatoid arthritis. Taking a structured medical history and performing a thorough clinical examination are crucial. The erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels are usually highly elevated and should be investigated particularly in patients who present with new onset bilateral shoulder pain and pronounced general impairment of movement. Imaging shows characteristic inflammatory changes around the shoulders and hip joints. The new European League Against Rheumatism and American College of Rheumatology (EULAR/ACR) classification criteria of PMR including ultrasound imaging are superior to previous classification and diagnostic criteria in terms of positive and negative predictive values. Glucocorticoids are still the mainstay of treatment. Recommended daily prednisolone starting doses are between 15 mg and 25 mg with a weekly dose reduction until 10 mg/day and then further dose reductions of 1 mg per month. Methotrexate can aid reducing prednisolone doses in patients who fail to reach doses below the Cushing threshold quickly enough, which can have major side effects." }, { "id": "pubmed23n0962_15295", "title": "Polymyalgia Rheumatica (PMR) with Normal Values of Both Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP) Concentration at the Time of Diagnosis in a Centenarian Man: A Case Report.", "score": 0.018433571185864764, "content": "The possibility that polymyalgia rheumatica (PMR) can be diagnosed when both ESR and CRP are normal at the time of diagnosis and before therapy with glucocorticoids, has been often discussed in the literature. We present a case report of a 100-year-old Caucasian man referred to our outpatient clinic, complaining of chronic pain in the shoulder and hip girdle associated with normal values of both ESR (21 mm/1st hour) and CRP (4 mg/dL). In the previous four months, several anti-inflammatory drugs and painkillers associated with physiotherapy treatments gave no significant improvement in pain and self-care. After an ultrasound (US) and an 18-fluorodeoxyglucose positron emission tomography associated with total body computed tomography (18-FDG PET/CT) examination, PMR was diagnosed and he started therapy with 17.5 mg prednisone, obtaining a fast improvement in pain and self-care. After 10 months of tapering, he stopped prednisone without relapse. During a 3-year follow-up, no alternative diagnosis was done.

The aching should be present for greater than one month. Polymyalgia rheumatica may be more common than reported. The etiology remains unknown. There is generally little found pathologically in this disease. The physical examination is often not impressive. Synovitis may be a main contributing factor to many of the symptoms seen in patients with polymyalgia rheumatica. Symptoms often do not correlate with physical findings. Polymyalgia rheumatica must be differentiated from many conditions since the diagnosis remains entirely clinical. Osteoarthritis, flu syndromes, inflammatory myopathies, fibromyalgia, and depression all have features that may mimic polymyalgia rheumatica. Malignancies and infections may also be difficult to separate from polymyalgia rheumatica. Polymyalgia rheumatica may also be extremely difficult to differentiate from seronegative rheumatoid arthritis in patients older than 50 years. Although some patients with polymyalgia rheumatica have underlying giant cell arteritis, the majority apparently do not. The distinction between polymyalgia rheumatica and giant cell arteritis cannot be made on the basis of laboratory studies and relies solely on clinical symptoms and physical findings. Although nonsteroidal antiinflammatory medications may control symptoms in patients with mild disease, most patients with polymyalgia rheumatica require low-dose corticosteroids. The tapering schedule for the corticosteroids is contingent upon the response of symptoms and laboratory parameters. Polymyalgia rheumatica usually follows a benign course with almost complete response to an adequate treatment program. Recently, there have been several studies suggesting that the course of polymyalgia rheumatica may not be as short and simple as once proposed. Nevertheless, many patients may be completely weaned from corticosteroids. Other agents have been used in this disease, but for the most part their use remains somewhat controversial.

A recent undertaking by the European League Against Rheumatism/American College of Rheumatology has led to the publication of provisional classification criteria of PMR. Ultrasonography, which is being increasingly used by rheumatologists, can greatly aid in the diagnosis of PMR and often shows changes of synovitis and tenosynovitis.

The current diagnostic criteria for PMR were empirically formulated by clinical experts who had studied the disease extensively. Arthroscopic, radioisotopic and magnetic resonance imaging studies all have indicated the presence of a synovitis in proximal joints and periarticular structures. The synovitis is probably responsible for the musculoskeletal symptoms in PMR. The prominence assigned to the proximal symptoms has probably overshadowed the less well recognized and more variable distal musculoskeletal manifestations which are present in about half of the cases. A normal erythrocyte sedimentation rate does not exclude a diagnosis of PMR. C-reactive protein and interleukin-6 seem to be more sensitive indicators of disease activity both at diagnosis and during relapse/recurrence. Corticosteroids are the drugs of choice for treating PMR. A course of treatment of 1-2 years is often required. However, some patients have a chronic, relapsing course and require low doses of corticosteroids for several years.

Recent clinical evidence and scientific results in the field have provided new challenges for rheumatologists. Besides the aspecific - although characteristic - proximal syndrome, less well recognizable and more variable distal musculoskeletal manifestations were observed. Magnetic resonance and ultrasound studies showed mild, remitting and non-erosive synovitis, with dominating inflammation of the extraarticular synovial structures. As no pathognostic sign is known, the diagnosis of polymyalgia rheumatica is based on its differential diagnosis, differentiation from the polymyalgia mimics; particularly from elderly onset inflammatory arthritides, such as elderly onset rheumatoid arthritis and late onset seronegative spondylarthritis. In 2012 the international polymyalgia rheumatica work group under the guidance of the American College of Rheumatology and European League Against Rheumatism elaborated new classification criteria, the scoring algorythm of which is based on clinical symptoms, with ultrasonography increasing the specificity. Corticosteroids remain the cornerstone of the therapy of polymyalgia rheumatica. No effective steroid-sparing drug has been found to date. Corticosteroids are generally needed for 1-1.5 years, though some patients have a chronic-relapsing course and require corticosteroids for several years. Well known corticosteroid-related side effects (diabetes, hypertension, hyperlipidaemia and osteoporosis) cause significant morbidity and economic burden on the society.

The etiology of the disease has not been hitherto clarified exactly. Its incidence among people over 50 is in the range of 0.1-0.5%. The incidence rate peaks in the age group of 60-70 years. It is also found in younger people, but far less frequently. The diagnosis is based primarily on locomotor complains--namely on pronounced pain, morning stiffness of the shoulder girdle, pelvic girdle and neck. Complaints relating to the arms and legs (such as muscular weakness, oedema, tendonitis etc.) are also observed, however, in one third of the cases. The diagnostic criteria are defined empirically. Polymyalgia rheumatica was formerly considered to be a form of elderly onset rheumatoid arthritis. The progressive erosion process is absent in the case of polymyalgia rheumatica unlike in the case of rheumatoid arthritis. Numerous factors are known, which point to a link between polymyalgia rheumatica and giant cell vasculitis, arthritis, but the precise nature of this relationship remains unknown. Both conditions affect the same age group in the general population and they are even found--not infrequently--in the same patient. Polymyalgia rheumatica can be found in 40% of the patients suffering from arthritis while the histological examination detected mild vasculitis in approximately 10% of the patients suffering for \"isolated\" polymyalgia rheumatica. The response to be given to the acute phase is similar in both disorders. Scandinavian authors consider polymyalgia rheumatica as the appearance of generalised arthritis. Arthroscopic, nuclear magnetic resonance imaging as well as isotopic studies show unequivocally, that in the background of the osteo-muscular symptoms, complaints, inflammation is to be found partly of the joints but primarily that of the periarticular synovial structures. The above mentioned--dominant--proximal symptoms can often mask the distal locomotor disorders (pitting oedema of the hands and feet, tendonitis, tendosynovitis, carpal tunnel syndrome). The disorder may be accompanied by atypical generalised symptoms (loss of appetite, weight loss, fever, fatigue). An excellent indicators of the acute phase reactions are erythrocyte sedimentation rate, C-reactive protein and interleukin-6. These are suitable for monitoring the effectiveness of the therapy, for indicating a relapse/recurrence. It should be noted, that polymyalgia rheumatica may also be present if the erythrocyte sedimentation rate and C-reactive protein values are low. This disorder is also characterised by fast and effective response to corticosteroid, which should be administered for 1-2 years. In some individual cases a different dosage regime may be necessary: steroid administered in low dosage over a longer period of time. Administration of methotrexate and anti-tumor necrotic factor-alpha may also be considered as alternative or adjuvant therapy for lowering the quantity of corticosteroid.

GCA occurs in people aged &gt;50 years and is more common in women. A higher incidence of the disease is observed in populations from Northern European countries. Polymyalgia rheumatica (PMR) is a periarticular inflammatory process manifesting as pain and stiffness in the neck, shoulders and pelvic girdle. PMR shares the same pattern of age and sex distribution as GCA. The pathophysiology of PMR and GCA is not completely understood, but the two conditions may be related and often occur concurrently. A delay in the diagnosis should be avoided because of the risk of vascular ischaemic complications due to GCA. The diagnosis should be considered in patients aged &gt;50 years presenting with symptoms such as new headache, visual disturbances, jaw claudication or symptoms of PMR. GCA can also present as a systemic inflammatory syndrome with fever of unknown origin. Marked elevation of acute-phase reactants, recognizable in higher erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels, is often seen in both PMR and GCA. However, some patients can present with a normal ESR. Confirmation of the diagnosis of GCA by temporal artery biopsy is important because clinical findings and laboratory tests are not specific, and because a diagnosis of GCA commits patients to long-term treatment with corticosteroids. The role of imaging techniques for the diagnosis of GCA remains unclear, but these modalities can be helpful in assessing the extent of vascular involvement, especially when extra-cranial disease is present. In PMR, subdeltoid and subacromial bursitis can be identified by imaging techniques, especially ultrasound or MRI. The clinical manifestations of GCA and PMR respond dramatically within 12-48 hours of starting corticosteroid treatment. The initial corticosteroid dosage commonly used in GCA is oral prednisone 40-60 mg/day, and for patients with PMR a dosage of 15-20 mg/day is often sufficient. A prolonged course of treatment is necessary, and corticosteroids are gradually tapered, guided by regular clinical evaluation and ESR (and/or CRP) measurement. Methotrexate is the best studied corticosteroid-sparing agent in GCA, and may be useful for patients with frequent disease relapses and/or corticosteroid-related toxicity. Retrospective studies favour aspirin (acetylsalicylic acid) as an effective adjuvant treatment for reducing the ischaemic complications of GCA. The long-term course of corticosteroid therapy frequently exposes elderly patients with PMR/GCA to various adverse effects, which can be attenuated with appropriate prophylactic measures. Co-morbid diseases and polypharmacy can pose particular challenges in the geriatric population. In general, the life expectancy of patients with GCA does not appear to be shortened, whereas the morbidity associated with the disease and its treatment is well recognized." }, { "id": "pubmed23n0363_5892", "title": "Polymyalgia rheumatica with normal erythrocyte sedimentation rate: clinical aspects.", "score": 0.013931254268153882, "content": "Polymyalgia rheumatica is a relatively common syndrome of the elderly characterized by severe pain and stiffness in the neck shoulder and pelvic girdles, along with increased acute phase reactants.

The wrist and knee are commonly affected by pseudogout and the first metatarsophalangeal joint or knee joint involvement may represent gout. Stiffness in the shoulder and hip girdles, worse in the morning, suggests polymyalgia rheumatica. In straightforward cases of OA no specific investigations are required. If doubt exists, however, tests may be necessary including FBC, ESR and CRP, uric acid for suspected gout and X-rays of the affected joints especially following trauma, or pseudogout. Patients with OA should be offered education and advice as well as strengthening exercises and aerobic fitness training (if physically possible). If the patient is overweight, weight loss is critical, especially in OA of the knee. Paracetamol and topical NSAIDs are the first-line drug treatments. Elderly onset RA differs from younger onset RA in the following ways: a more balanced gender distribution; a higher frequency of acute onset; an association with systemic features; more frequent involvement of the shoulder girdle and higher disease activity.

Despite all the knowledge about the beneficial effects of corticosteroid treatment, data concerning the optimal dosage regimen are lacking. Long-term corticosteroid use can be associated with various adverse events, of which induction of osteoporosis, diabetes mellitus and infection among the worst. A Corticosteroid Side Effect Questionnaire has been shown to dose-dependently detect adverse effects perceived by patients. The European League Against Rheumatism (EULAR) response criteria for PMR comprise a core set of markers for monitoring therapeutic responses in PMR, namely ESR or CRP, the visual analogue scale of patient's pain and physician's global assessment, as well as morning stiffness and the ability to elevate the upper limbs. The PMR-disease activity score has been developed on the basis of EULAR response criteria as a means of expressing disease activity as an absolute number. A score &lt;7 indicates low disease activity, scores 7-17 suggest medium activity, and a score &gt;17 is indicative of high disease activity. The PMR-disease activity score has been proven to be highly correlated with patient's global assessment, patient satisfaction and ESR. It provides an easily applicable and valid tool for disease activity monitoring in patients with PMR. Improved knowledge of disease activity processes, exact monitoring of disease activity and treatment responses, and increased risk-estimation of treatment schedules should ultimately improve the care of patients with PMR." } ] } } }

It develops insidiously, and in many cases, particularly in developed countries, no antecedent diagnosis can be found. These cases are termed idiopathic. Tuberculosis is the leading cause of constrictive pericarditis in developing nations but represents only a small minority in developed countries. Here the authors describe two different case reports where tuberculosis was the probable cause of CCP. A 21-year-old man born in Cape Verde living in Europe for 4 years and a 24-year-old man born in Guiné Bissau were both admitted due to intense precordial pain and syncope after exertion. Interestingly both had fatigability, dyspnea, chest discomfort and palpitations on exertion, as well as progressive involuntary weight loss and decubitus cough. On physical examination they had tachycardia, jaundice, cachexia, elevated jugular venous pressure, hepatomegaly and ascites. Both electrocardiograms showed prominent P waves and chest X-ray showed bilateral pulmonary interstitial infiltrates and enlargement of the right cavities. Analytically, elevated bilirubin, leukopenia and thrombocytopenia was also found in both. Echocardiography revealed findings, in both cases, compatible with CCP including less common signs as annulus reversus and annulus paradoxus. Thoraco-abdomino-pelvic CT from both patients revealed chronic liver disease with congestion, pleural effusion, pericardial calcifications, ascites and massive mediastinal and abdominal adenopathies. Blood cultures and IGRA test were negative. However, given the presumptive diagnosis of tuberculosis (TB), anti-TB therapy was started. Despite the diagnosis of \"end-stage\" CCP with very high operative risk multidisciplinary team decided after informed consent, to perform total anterior pericardiectomy, that occurred without complications. Pericardial and mediastinal biopsies, pericardial/pleural fluid cultures/ immune-phenotyping were inconclusive. Anti- tuberculosis therapy was maintained. After surgery, the patients had a remarkable clinical improvement (NYHA I) that persisted in 6- month follow-up. These two case reports illustrate that despite the markedly elevated operative risk of pericardiectomy in \"end-stage\" forms of disease after patients informed consent must be a considered option. The other point to consider is that, despite rare, tuberculosis still is a possible diagnosis to consider in CCP in Portugal." }, { "id": "pubmed23n0052_18986", "title": "[A case of subacute effusive-constrictive pericarditis].", "score": 0.01369485294117647, "content": "A 30-year-old female with effusive-constrictive pericarditis was admitted to our hospital because of dyspnea, ascites and edema.

His family physician suspected febrile tracheobronchitis and treated it with ampicillin for 5 days. Because symptoms persisted an ECG was done which suggested acute myocardial infarction. The patient underwent an emergency coronary angiography which excluded coronary artery disease and aortic dissection. Pericarditis was suspected and the patient put on aspirin, 500 mg/d. Because of persisting cardiac symptoms an echocardiography was performed which revealed systolic separation between epi- and pericardium, characteristic of a small pericardial effusion after acute pericarditis. The symptoms improved after one week of treatment with diclofenac and the ECG had become normal. Two months later the patient was seen at our cardiac outpatient clinic. He had night sweats, sporadic precordial pain and severe dyspnoe. Further investigations revealed tachycardia (120/min), hypotension (95/70 mm Hg), pulsus paradoxus and jugular vein sustension. Echocardiography revealed a large pericardial effusion (\"swinging heart\"), which explained the low voltage and the electrical alternans in the ECG. Pericardiocentesis was carried out the same day to relieve the tamponade. It was followed by pericardioscopy and epi- as well as pericardial biopsy. 485 ml of a serous effusion were drained. Cytology and histology demonstrated a lymphocytic fibrinous pericarditis. Polymerase chain reaction (PCR) on viral and bacterial RNA and DNA of potentially cardiotropic agents remained negative.

It's usually challenging to distinguish acute pericarditis from ST-elevated myocardial infarction (STEMI) due to the similar ECG characteristics (ST segment change). Here we present a case of purulent pericarditis probably caused by esophageal perforation. <bCase:</b A 52 year-old male presented with chest pain and dyspnea for 16 h. ST-segment elevation and positive cardiac markers lead to the initial diagnosis of ST-elevated myocardial infarction. Coronary angiography demonstrated normal coronary artery, while transthoracic echocardiography (TTE) showed massive pericardial effusion. Then, pericardiocentesis was performed with 250 ml of yellowish-green pus-like fluid extracted. A detailed history examination revealed a week history of possible esophageal perforation caused by a fishbone. And a further computed tomography (CT) demonstrated the presence of pneumomediastinum, and effusions in mediastinum, which lead to the diagnosis of purulent pericarditis. However, the patient's family refused further treatment and the patient died soon after discharge. <bConclusion:</b The differential diagnosis of chest pain should include acute pericarditis, which can be equally critical and fatal. And it's important to note the peculiar characteristics of acute pericarditis, which include concave and diffused ST-segment elevation, PR segment depression, and the ratio of ST-segment elevation to T wave &gt;0.24 in lead V6. Moreover, comprehensive medical history and physical examination are crucial to the differential diagnosis of chest pain patients." }, { "id": "article-18905_7", "title": "Cardiac Tamponade -- History and Physical", "score": 0.010744603444094105, "content": "Patients with cardiac tamponade present similar to patients with other forms of cardiogenic or obstructive shock.

We report a complex case of an older woman who developed autoimmune hemolytic anemia and sixth cranial nerve palsy that posed considerable challenges in diagnosing late-onset SLE. CASE REPORT A 78-year-old Japanese woman presented with polyarthritis associated with generalized fatigue for 2 months, who later developed diplopia. Physical examination revealed conjunctival pallor, polyarthritis, and subsequent development of sixth cranial nerve palsy. Laboratory data revealed a decreased white blood cell count; macrocytic anemia; elevated levels of lactate dehydrogenase, indirect bilirubin, and erythrocyte sedimentation rate; hypocomplementemia; positive Coombs test; antinuclear antibodies (ANAs, 1: 40); and positive anti-double-strand DNA antibodies. Lymphoma, cerebral venous sinus thrombosis, and varicella-zoster virus infection were unlikely based on head computed tomography, brain magnetic resonance imaging, and cerebrospinal fluid analysis. She was diagnosed with late-onset SLE associated with autoimmune hemolytic anemia and sixth cranial nerve palsy. The patient was successfully treated with prednisone and hydroxychloroquine. CONCLUSIONS The difficulty in diagnosing late-onset SLE with atypical presentations and uncommon complications must be recognized. SLE cannot be excluded based on a low titer of ANA in a particular subgroup such as the elderly, and the prozone effect should be considered responsible for low ANA titers. In this case, late-onset SLE was diagnosed by considering multisystem pathologies despite low ANA titers." }, { "id": "pubmed23n0297_3204", "title": "[Autoimmune hemolytic anemia with eosinophilia in elderly patient].", "score": 0.018452380952380953, "content": "A 70-year-old woman was admitted to our hospital in November 1992 for evaluation of anemia.

Among the 236 SLE patients 168 (71.18%) had hematological abnormalities and 68 of them (28.82%) without hematological abnormalities. 123 of the 168 patients with hematological abnormalities (52.1%) had anemia, 82 of which (66.7%) had characteristics of anemia caused by chronic diseases, 18 (14.6%) had hemolytic anemia, 8 (6.6%) had hematopoietic abnormalities, and the remaining 15 patients (12%) had anemia caused by unknown reasons. 73 of the 236 SLE patients (30.9%) had a WBC count &lt; 4.0 x 10(9)/L and 57 patients (24.2%) had a platelet count &lt; 100 x 10(9)/L.

The reason of the high proportion of anemia among the SLE patients in China may be the higher proportion of anemia caused by ACD in comparison with that abroad. Although SLE patients have lower rates of hemolytic anemia, HA is an important index of SLE disease activity. Thrombocytopenia and a WBC count &lt; 3.0 x 10(9)/L are related to SLE disease activity.

When the breast is involved, the term lupus mastitis (LM) is used. This disease involving the breast is rare, and the lesions may precede, coincide with, or occur later than the onset of other lupus lesions. Tissue biopsy is required to confirm the suspected diagnoses of LM. We report a case of a patient with lupus mastitis due to the important differential diagnosis. A 60-year-old woman presented with a painful nodular lesion in her left breast that had appeared 15 days ago (Figure 1, a). She had been previously diagnosed with discoid lupus erythematosus 3 years ago. Physical examination revealed a deep and firm erythematous subcutaneous nodule without overlying skin involvement in the lower-central portion of the left breast. Laboratory findings were positive for antinuclear antibodies (1:80) and double-stranded deoxynucleic acid antibodies (1:10). Mammography and ultrasounds showed an area of increased density and irregular breast tissue along with an important thickening of the overlying skin (Figure 1, b). On suspicion of malignancy, a needle biopsy of the breast lesion was performed and showed vacuolar alteration and lymphocytic infiltrate in the basal layer. Subcutaneous fat showed a lobular panniculitis with a prominent lymphocytic infiltrate and hyalinization of the fat lobules (hyaline fat necrosis). Direct immunofluorescence of the face biopsy revealed IgA, IgG, IgM, and C3 granular deposition. Based on these results, a diagnosis of lupus mastitis associated with DLE was established. Antimalarial therapy resulted in complete resolution of the clinical features. Three years later, the patient presented with a disfiguring atrophy with retraction in the damaged areas of the breast (Figure 2). Lupus mastitis is a very unusual disease that most commonly affects middle-aged women. The first case of LM was described by Tuffanelli in 1971. The lesions usually present following the diagnosis of SLE/DLE; however, on rare occasions they may be observed earlier (2). The histophysiology of this disease remains unclear, but the predominant theory suggests an autoimmune-related etiology. Corroborating evidence for this theory includes the finding of immune complexes, both at the basement membrane of the dermal-epidermal junction and in the blood vessels in the areas of panniculitis (3). Lupus mastitis may be present in the breast as single or multiple subcutaneous nodules that may be tender or painful and can progress to chronic ulcers over time or resolve, leaving atrophic scars. The overlying skin can be normal, erythematous, poikilodermic or ulcerated. When skin changes are prominent, the lesion may clinically and radiologically mimic inflammatory breast carcinoma. Mammographic and ultrasounds findings include an ill-defined breast density with or without associated microcalcifications (4). Histologically, this disease is characterized by lobular lymphocytic panniculitis and predominantly involves the fat lobule and the presence of anucleated adipocytes in a background of a glassy-appearing collagenous stroma (hyaline fat necrosis). Fibrinoid necrosis of the vessel wall has also been reported, but is usually absent (5). Differential diagnosis of lupus mastitis includes inflammatory breast carcinoma, primary medullary carcinoma, and other immune-mediated inflammatory conditions such as diabetic mastopathy. The first line of treatment the use of antimalarial drugs such as hydroxychloroquine. Systemic steroids and cyclophosphamide have also been used. Surgical treatment should be considered only in patients who do not respond to management with medications. In summary, we reported a case of lupus mastitis in a patient with discoid lupus erythematosus. This dermatosis should be considered in the differential diagnosis of breast lesions in lupus patients, and a biopsy of the breast lesion is essential to reject suspected malignancy. If the disease is left untreated, unsightly atrophy will appear; it is thus important to diagnose early on. The course of the disease tends to be chronic with remission and flares, so patients should be followed-up regularly due to the risk of recurrences in the same area or in a different location." }, { "id": "article-22714_13", "title": "Hemiballismus -- Evaluation", "score": 0.009174311926605505, "content": "Thorough routine serum labs, depending on suspected etiology, can include a complete metabolic panel (CMP) and complete blood count (CBC), hemoglobin A1C, serum osmolality, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), anti-nuclear antibody (ANA), extranuclear antibody (ENA), vitamin panel (e.g., B1, B12, etc.), ceruloplasmin, copper level, other heavy metals, drugs of abuse toxicology, HIV antibody screen (if positive opportunistic infection screen), lupus antibodies (C3/C4, double-stranded DNA, anti-histone), antineutrophil cytoplasmic antibodies (ANCA) studies, cryoglobulin, among other immune and infectious markers." }, { "id": "pubmed23n0311_6890", "title": "[A man with systemic lupus erythematosus presenting with spastic paraplegia].", "score": 0.00909090909090909, "content": "We report a 38-year-old man systemic lupus erythematosus who presented with an acute onset of paraplegia and urinary retention.

It was initially reported by Rowell (1) in 1963 and its existence as a separate clinical entity is currently under debate (2,3). A few cases may have been induced by drugs such as systemic antimycotics, antibiotics, anticonvulsants, and more recently proton pump inhibitors (PPIs). CASE REPORT We present the case of a 67-year-old woman with subacute cutaneous lupus erythematosus (SCLE) and EM-like lesions who fulfilled all the criteria for Rowell's syndrome. The patient had lupus arthritis for two years and was treated with oral methylprednisolone 8 mg/day and hydroxychloroquine 200 mg/day. She started receiving 20 mg of omeprazole daily for gastroprotection. The patient also had arterial hypertension with no current treatment, osteoporosis, and an L1 vertebral fracture. The dermatological examination revealed multiple erythematous infiltrated plaques involving mainly the sun-exposed areas (neck, chest, upper back, and shoulders). Cutaneous lesions had an annular or target pattern and a tendency to form hemorrhagic crusts and scales at the margins (Figure 1, A). The mucous membranes were unaffected. Histological examination (hematoxylin and eosin ×200) found epidermal atrophy, vacuolar degeneration of the basal layer, and sparse perivascular lymphocytic infiltrate in the dermis - features corresponding to lupus erythematosus (Figure 2, A). Single eosinophilic necrotic keratinocytes characteristic for erythema multiforme were observed in the epidermis (Figure 2, B). Direct immunofluorescence (IF) from lesional skin showed granular deposits of C3 on the dermo-epidermal junction. Lupus band test from sun-protected, nonlesional skin was negative. On indirect IF a speckled pattern antinuclear antibodies (ANA) with &gt;1:1280 titers were detected. Anti-Ro (&gt;200 U/mL) and anti-La (&gt;200 U/mL) antibodies were also positive. The blood cell count and differential analysis were within reference ranges. The 24-hour urine protein test showed a non-significant proteinuria - 0.36 g/24h. Photo-testing was impossible considering the extent of the skin lesions. The therapeutic approach consisted of increasing the hydroxychloroquine dose to 400 mg/day, substituting PPI with famotidine 20 mg/day p.o. and ceftriaxone 2 g/day for the superinfection with Ps. aeruginosa, which led to a clinical improvement (Figure 1, B). The methylprednisolone dose remained unchanged due to already existing severe adverse effects. DISCUSSION The diagnosis was based on Zeitouni et al.'s classification (4). The three main criteria are as follows: lupus erythematosus, EM-like lesions, and speckled pattern of ANA. Our patient met all three major and one minor criteria, namely the presence of anti-Ro and anti-La antibodies. As for the other minor criteria, RF was negative and no chilblains were found. Although there was a continuous time lapse (more than 1 year) between the initiation of omeprazole intake and the diagnosis of Rowell's syndrome, we suggest that the connection is probable. For instance, the latency differs depending on the incriminated medication in drug induced SCLE. Longer periods are reported for diuretics and calcium blockers, while the time interval is shorter for chemotherapeutic drugs and antimycotics (5). Our suspicions were further confirmed by the fact that the lesions improved promptly within a month after discontinuation of omeprazole and doubling the dose of hydroxychloroquine. PPIs are reported to be a major cause of drug-induced SCLE (6,7). According to Laurinaviciene et al., the most common drugs involved are PPIs, thiazide diuretics, antifungals, chemotherapeutics, statins, and antiepileptics (6). However, very few cases of Rowell's syndrome are found to be drug-related. The culprit drugs include: oral terbinafine (8,9), norfloxacin (10), sodium valproate (11) and esomeprazole (12) (Table 1). CONCLUSION Despite the common clinical and immunological features shared between SCLE, drug-induced SCLE and EM, Rowell's syndrome seems to be a separate entity rather than a coincidental association. Finally, according to our knowledge this case would be the second of Rowell's syndrome due to PPIs." }, { "id": "pubmed23n0113_14990", "title": "Haematological abnormalities in a 75-year-old population.

Cutaneous involvement, either alone or in association with other systemic illnesses, is one of its most common manifestations (1). Dermatologic disorders like malar and discoid rashes are quite suggestive of SLE. However, the occurrence of non-specific skin lesions like erythema multiforme (EM) in patients with SLE (Rowell syndrome) can rarely occur (1). In such patients, a diagnosis of SLE may be missed or delayed in the absence of other overt clinical features of lupus. Herein we report a case of recurring EM-like eruptions as the cardinal cutaneous manifestation of previously undiagnosed, active SLE in a young Nigerian woman. A 26-year-old Nigerian woman presented with a three-day history of non-pruritic, generalized, and target-like, erythematous annular patches and plaques which mostly affected the trunk. A few lesions had presented with crusting and erosions at the time of examination (Figure 1). Associated symptoms included oral painful ulcers, low grade fever, and malaise. The patient had no other systemic symptoms and her prior drug history was not remarkable. Her erythrocyte sedimentation rate (ESR) was 66 mm/hour using the Westergren method. Screening for HIV and hepatitis B and C was negative. Herpes simplex, cytomegalovirus, and Epstein Barr viruses could not be screened for. Other baseline investigations (complete blood count, electrolytes, urea and creatinine as well as urinalysis) were within normal limits. The patient was managed as a case of EM of an unidentified inciting agent and her symptoms resolved with supportive care and antibiotics. However, she developed a recurrence about 5 weeks later, with more extensive and coalescent skin lesions (Figure 2). Additionally, there was a new onset of alopecia and pain in the small joints of the hands as well as both knees and ankles. At this time, the patient's ESR had gone up to 112 mm/h and she had developed significant proteinuria, with a protein creatinine ratio of 1.3 g/g (reference &lt;0.5 g/g). Her antinuclear antibody (ANA) titer was high (1:320) with a speckled pattern. Anti-Smith antibody was also positive. A renal biopsy was declined. A tentative diagnosis of Rowell syndrome was made. The patient was started on high-dose steroids and hydroxychloroquine 200 mg twice daily. Subsequent care included the use of mycophenolate mofetil 1 g twice daily for 6 months. This was then changed to azathioprine at 50 mg twice daily. Follow-up after 6 months showed sustained clearance of skin lesions, resolution of fever and joint pains, as well as improvement in the renal profile, with a urine protein-creatinine ratio of 0.77 g/g. The presence of systemic lupus erythematosus, EM-like lesions, and a speckled pattern of antinuclear antibody in our patient fulfils the revised diagnostic criteria for RS put forward by Zeitouni et al. at the turn of the twenty-first century (2). Considering the rarity of EM-like lesions in SLE and the possibility of constitutional symptoms in EM, a diagnosis of RS may be readily overlooked in patients like the one described, whose major cutaneous manifestation of severe active SLE was EM-like lesions. In contrast to classic EM, where skin lesions are concentrated in the extremities, a predominant truncal distribution of EM-like lesions as found in our patient may favor a clinical consideration of RS (3). However, some authors have challenged the existence of Rowell syndrome as a distinct clinical laboratory entity. Arguments put forward in this regard include the fact that none of the immunological markers that have been described in RS are specific to any disorder. Additionally, the annular polycyclic dermatosis seen in sub-acute cutaneous lupus erythematosus (SCLE) can be difficult to clinically and histologically differentiate from EM (4,5). Patients with SLE also have a higher likelihood of developing adverse drug reactions (6). The inherent complexity of SLE may make for delayed and oftentimes difficult diagnosis, especially in a country where immunologic tests are expensive and rheumatologists are scarce. When patients do occasionally present with recurrences of skin lesions in the spectrum of EM, Steven-Johnson syndrome, and toxic epidermal necrolysis in the absence of a definite inciting agent, undiagnosed lupus may indeed be present in some of these individuals and should be considered in the differential diagnosis. In conclusion, while it is very rare, SLE may present first with recurrent episodes of EM-like rash. Despite the various possibilities which underlie their association, prompt identification and treatment of SLE in patients presenting with EM is important to prevent death or irreversible organ damage." } ] } } }

The correct answer is 3. In the inguinal region, the lymph nodes can acquire a size of up to 1.5 cm being normal. In addition, the rest of the data of the inguinal exploration (no pain, mobile, soft, etc.) corroborates this. On the other hand, there are no signs or symptoms that make us think of a sexually transmitted infection.

The ulcer sometimes called a \"soft chancre,\" will have soft and irregular margins with a friable base and a grayish-yellowish exudate. It tends to bleed easily. The ulcers are typically 1 cm to 2 cm in diameter and usually resolve spontaneously within three months, even if left untreated. Close to half of the affected individuals will develop regional lymphadenopathy, which may be tender.

Without treatment, it goes through the following stages: primary, secondary, latent, and tertiary (1). The clinical picture of secondary syphilis is very variable (2,3). We present two rare cases of secondary syphilis, one with nodular lesions initially considered to be lymphoma and second with periostitis, which was initially interpreted as an osteoma. To date, only 15 cases with nodular lesions and 10 cases with periostitis in secondary syphilis have been reported in the literature. The first patient was a 59 year old man who presented in a private practice with nodular lesions on the face and axillary and inguinal folds (Figure 1, a, b). The initial diagnostic consideration was lymphoma. A biopsy specimen was taken, and the histopathological features revealed epidermal hyperplasia with papillomatosis, minimal spongiosis with many neutrophils and with a marked inflammatory infiltrate in dermis, consisting of lymphocytes, plasma cells, and neutrophils; the diagnosis of interfaced dermatitis was established (Figure 1, d, e). After one month, the patient presented to our clinic with numerous nodular lesions, some of them painful, located on the trunk and intertriginous folds, including the intergluteal cleft - the lesions in this area being suggestive of condylomata lata (Figure 1, c). The diagnosis of secondary syphilis was taken into consideration, and screening serum tests were performed and found reactive: a Venereal Diseases Research Laboratory (VDRL) titer of 1:64 and Treponema pallidum Hemaglutination Assay (TPHA) titer of 1:80. Hepatitis and anti-human immunodeficiency virus (HIV) antibodies serology was negative. The biopsy was repeated and showed the same histopathological changes. In addition, Warthin-Starry staining was performed, revealing the presence of some spiral micro-organisms in the dermis corresponding to Treponema pallidum (Figure 1, f). A diagnosis of secondary syphilis was established, and the patient was treated with benzathine penicillin G 2.4 million units by intramuscular injection once a week for 2 consecutive weeks. The skin lesions regressed within 1 month, and serological tests showed a VDRL titer of 1:8 3 months after treatment. The second patient was a homosexual male, 35 years old, diagnosed with HIV infection, stage B2. He presented with bone pain in the calves and forearms, with insidious onset. He also presented with an associated erythematous maculo-papular rash on the trunk and limbs and generalized lymphadenopathy (Figure 2, a, b). The tibial crest and radius were sensitive to palpation. A right leg radiography was performed, raising suspicion of osteoid osteoma. The CT scan excluded the diagnosis of osteoma; taking into account the epidemiological context, the diagnosis of syphilis was suspected. The diagnosis was confirmed by leg ultrasound examination (2D US) which showed thickening of the compact tibial bone associated with subperiosteal destructive and proliferative changes (Figure 2, c, d) and by serology for syphilis: the VDRL titer was 1:32 and the TPHA titer was 1:80. The patient was treated with benzathine penicillin 2.4 million units, once a week, for 2 consecutive weeks, with clinical improvement. Syphilis continues to be a serious public health problem worldwide, even if it is a controllable disease due to diagnostic tests and effective and accessible treatment. According to the World Health Organization in 2008, the estimated number of new cases of sexually transmitted diseases in adults with syphilis is 10.6 million cases (4). The cases presented in this paper were characterized by unusual manifestations, requiring good collaboration between the dermatologist and other specialties. In the first case, the diagnosis of secondary syphilis was confirmed by positive serological, clinical, and histopathological findings. The main differential diagnosis of nodular syphilis includes lymphoma, sarcoidosis, Kaposi's sarcoma, atypical mycobacteriosis, deep fungal infections, leprosy, tuberculosis, leishmaniasis, and lymphomatoid papulosis (5). Another important differential diagnosis is between secondary and tertiary syphilis, especially when ulcerating nodules are present. Tertiary syphilis is characterized by unilateral, deep ulcerating nodules with necrotizing granulomas (6). Bone involvement during syphilis is mainly represented by polyarthritis, synovitis, osteitis, and periostitis (7,8). Syphilitic periostitis is characterized by localized or diffuse pain, particularly during the night, which is relieved by movement. The skull, the shoulder girdle, and the long bones are the most common sites of involvement (9). In conclusion, we presented two different cases of secondary syphilis that contribute to the clinical experience of rare cases presented in the literature, raising the awareness of dermatologists and other specialists about less specific clinical aspects of syphilis." }, { "id": "wiki20220301en032_60070", "title": "Lymphadenopathy", "score": 0.009433962264150943, "content": "Lymph node enlargement is recognized as a common sign of infectious, autoimmune, or malignant disease.

Learning points from this case: (1) Although routine administration of antibiotic to a spinal cord injury patient with pyrexia may be acceptable in outpatient setting, other possibilities such as infection by multi-drug resistant organism, viral infection, venous or, arterial thrombosis should be considered if a patient does not respond promptly to antibacterial therapy. (2) When full blood count showed lymphocytosis (comprising &gt; 50% of white blood cells) with atypical morphology, lymphocyte surface markers, Paul Bunnell test, and Epstein Barr virus serology should be performed. These tests would have led to a diagnosis of infectious mononucleosis, and abdominal imaging studies could have been avoided.

The therapeutic approaches to heart failure have undergone considerable changes during the last few years. The guidelines have to be updated almost yearly due to new results from prospective randomized studies. Although an agreement could be reached with respect to general measures and drug treatment, no agreement on mechanical devices, pacemakers and surgical interventions has been reached. The basis for medical treatment of chronic heart failure depends on diuretics, digitalis, ACE inhibitors, and beta-blockers. Calcium antagonists and other positive inotropic drugs, other than digitalis, should be avoided as far as possible. Thiazides, loop diuretics and aldosterone antagonists are needed for acute and chronic treatment of heart failure, alone or in combination (diuretic resistant heart failure!). Digitalis glycosides are needed in patients with atrial fibrillation with a fast ventricular rate or atrial flutter and in patients with systolic dysfunction, large hearts and symptomatic failure class NYHA III and IV. However, digitalis does not convert atrial fibrillation to sinus rhythm. Today there is no question that ACE inhibitors improve the prognosis of all patients with heart failure in all stages, if ejection fraction is reduced. Therefore, most patients after myocardial infarction or after having experienced pump failure due to myocarditis or cardiomyopathy are treated with ACE inhibitors and diuretics. The beneficial effects of ACE inhibitors seem to be most pronounced the worse the situation is. Relative risk reductions (mortality!) between 10% and 40% have been published depending on the severity of symptomatic left ventricular dysfunction. Those patients with high absolute risk have more to gain than those with low risk for any given \"risk reduction\", of course. Recent studies also indicate that most high risk cardiac patients profit from ACE inhibitors even if pump function is normal (i.e., patients with coronary heart disease, diabetes mellitus, cerebral vascular disease, hypertension) (15). AT1 antagonists can substitute for ACE inhibitors, if the latter are not tolerated due to cough. Up to now, beta-blocking agents apart from diuretics seem to be the best investigated drugs in heart failure. Large controlled studies with bisoprolol, carvedilol and metoprolol in addition to diuretics, digitalis and ACE inhibitors convincingly yielded positive results in chronic left ventricular failure patients. Reduction of mortality by 35% and even of sudden cardiac deaths by 40% have been proven beyond doubt. Thus, heart failure patients today should also receive beta-blocking agents in all stages of the disease. In the era of controlled prospective studies (evidence-based medicine), physicians are well advised to use only drugs that have been proven beneficial in large controlled studies." }, { "id": "pubmed23n0764_21395", "title": "Cardiovascular medication in relation to renal function after coronary artery bypass surgery.", "score": 0.009259259259259259, "content": "Guidelines for recommended medication use for the secondary prevention of coronary heart disease are exceedingly important in patients with chronic kidney disease.

We ascertained the incidence of AKI and hyperkalemia during each quarter on the basis of having at least 1 payment claim for the condition. We used Poisson regression with robust SEMs to formally test for changes in the trend and level of antihypertensive medication use in a series of intervention analyses. The number of antihypertensive drugs used increased as patients neared ESRD, peaking at an average of 3.4 in the quarter immediately preceding dialysis initiation, then declining to 2.2 medications by 2 years later. Angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker use was stable at approximately 40%, even among patients with coronary disease and systolic heart failure, and did not correlate with AKI or hyperkalemia. Dialysis initiation was associated with a 40% (95% confidence interval, 38% to 43%) lower adjusted level of diuretic use, which continued to decline after ESRD. Three- and four-drug combinations that included a diuretic were most common before ESRD, whereas after ESRD, one- and two-drug β-blocker or calcium-channel blocker-based combinations were most common.

The diuretics have recently regained prominence, largely due to the results of recent controlled trials. These trials in elderly patients demonstrated that low-dose diuretics were effective not only in preventing stroke but also in greatly reducing coronary-related events. Diuretics also decrease left ventricular mass more than the other major drug classes. In addition, they are the most effective drugs for use in combination therapy. By contrast, the safety of calcium antagonists has recently been questioned because of report of increased coronary morbidity and mortality. However, these adverse events may be restricted to the short-acting preparations, especially nifedipine, which causes cardiac stimulation. ACE inhibitors, like beta-blockers, are not only effective in reducing blood pressure, particularly when combined with a diuretic, but also improve angina and decrease postinfarction mortality. They also benefit congestive heart failure, stabilise or improve renal function in hypertensive and diabetic nephropathy and reduce albuminuria. Beta-Blockers are especially effective in reducing sudden cardiac death in patients with coronary heart disease, particularly in postinfarction patients. Final proof of the relative effectiveness of these drugs in preventing morbidity and mortality must await the outcome of large comparative trials currently under way. A recent national survey in the US found that more than 75% of hypertensive patients did not have their hypertension completely controlled. Possible reasons for this disturbing statistic are discussed along with suggestions for improvement." } ] } } }

Tongue deviation due to muscle weakness on one side is common in brain stem stroke and is usually associated with dysarthria and dysphagia that decrease the patient's quality of life. This case report presents a typical but rarely discussed case of tongue deviation secondary to a brain stem stroke. In addition, it also offers a concise review of both the ipsilateral and the contralateral cortico-hypoglossal fibers that innervate the hypoglossal nucleus. Even though the direction of the tongue deviation offers essential clues to localizing the brain lesion, many providers lack experience and knowledge in this area. CASE REPORT We report the case of an 81-year-old right-handed male patient with right-sided hemiparesis, right lower facial droop, dysarthria, and tongue deviated to the right side without fasciculation or atrophy. The Babinski sign was positive on the right. Magnetic resonance imaging revealed an infarct in the left paramedian pontine. Since both the tongue deviation and the hemiparesis were right-sided, contralateral to the side of the lesion, we concluded that the lesion affected the cortico-hypoglossal fibers and the corticospinal fibers prior to their decussations. CONCLUSIONS The case report reviews the projections of the corticospinal fibers. Each hypoglossal nucleus receives input from both hemispheres, with the contralateral descending fibers passing through the medial part of the ventral pons and the ipsilateral descending fibers passing through the more lateral aspect of the pons.

The tract begins in the primary motor cortex, where the soma of pyramidal neurons are located within cortical layer V. Axons for these neurons travel in bundles through the internal capsule, cerebral peduncles, and ventral pons. They stay in the ventral position within the medulla as the pyramids. A majority of the axons cross the midline at the pyramidal decussation between the brainstem and spinal cord to form the lateral corticospinal tract (Figure 1A). This crossover causes the left side of the brain to control the right side of the spinal cord and the right side of the brain to control the left side of the spinal cord. A small number of axons remain on the ipsilateral side to form the anterior corticospinal tract. Axons of both anterior and lateral corticospinal tracts move into the gray matter of the ventral horn to synapse onto lower motor neurons. These lower motor neurons exit the spinal cord to contract muscle. [1] While the anterior corticospinal tract assists with axial muscle motor control, the lateral corticospinal tract is the primary pathway for motor information to the body. Injuries to the lateral corticospinal tract results in ipsilateral paralysis (inability to move), paresis (decreased motor strength), and hypertonia (increased tone) for muscles innervated caudal to the level of injury.

Symptoms started plainly with sudden general impairment, intense asthenia, headache, abdominal pain and confusion. After 48 hours, the patient was first admitted to an emergency unit and transferred to an internal medicine ward afterwards. She kept confused. Her behaviour was bizarre with permanent swinging of pelvis, mannerism, answers off the point and increasingly poor. The general clinical examination was normal, except for the presence of a regular tachycardia (120 bpm). The paraclinical investigations also showed normal: biology, EEG, CT Scan, lumbar puncture. Confusion persisted. The patient remained stuporous, with fixed gazing and listening-like attitudes. She managed to eat and move with the help of nurses but remained bedridden. The neurological examination showed hypokinaesia, extended hypotonia, sweating, urinary incontinence, bilateral sharp reflexes with no Babinski's sign and an inexhaustible nasoorbicular reflex. The patient was mute and contrary, actively closed her eyes, but responded occasionally to simple instructions. For short moments, she suddenly engaged in inappropriate behaviors (wandering around) while connecting back to her environment answering the telephone and talking to her parents. The patient's temperature rose twice in the first days but with no specific etiology found. During the first 8 days of hospitalization, an antipsychotic treatment was administered: haloperidol 10 mg per os daily and cyamemazine 37.5 mg i.m. daily. Despite these medications, the patient worsened and was transferred to our psychiatric unit in order to manage this catatonic picture with rapid onset for which no organic etiology was found. On admission, the patient was stuporous, immobile, unresponsive to any instruction, with catalepsy, maintenance of postures, severe negativism and refusal to eat. A first treatment by benzodiazepine (clorazepate 20 mg i.v.) did not lead to any improvement. The organic investigations were completed with cerebral MRI and the ruling out of a Wilson's disease. Convulsive therapy was then decided. It proved dramatically effective from the first attempt; 4 shocks were carried out before the patient's relatives ask for her discharge from hospital. The patient revealed she had experienced low delirium during her catatonic state. The clinical picture that followed showed retardation with anxiety. She was scared with fear both for the other patients and the nursing team. She kept distant and expressed few affects. The treatment at the time of discharge was olanzapine 10 mg per os. She was discharged with a diagnosis of catatonia but with no specific psychiatric etiological diagnosis associated. She discontinued her follow-up a few weeks later. After one year, we had no information about her. Catatonia has now become rare but remains a problem for clinicians. We reviewed data concerning short term vital prognosis and psychiatric long term prognosis in catatonia.

There is no known antidote to olanzapine intoxication. Overdosing olanzapine can cause, tremor, bradykinesia, hypotension somnolence, coma, and miosis. CASE REPORT We present the case of a previously healthy 69-year-old man who after routine mitral valve surgery developed pneumonia and severe sepsis requiring several weeks on a ventilator in the Intensive Care Unit. He developed delirium and paranoia and was prescribed olanzapine. After 4 doses, he became hypotensive and nonresponsive and developed pinpoint pupils. The symptoms were reversed minutes after administration of flumazenil. The clinical picture in this case corresponds well with an olanzapine intoxication. No other drugs, such as benzodiazepines or opioids, had been administered that could explain the reaction. Olanzapine intoxication is known to present with hypotension, coma, and miosis. The doses given were normal starting doses for olanzapine in the outpatient setting but much higher than recommended doses in the intensive care setting. CONCLUSIONS This case illustrates a risk for severe adverse effects, even within normal prescription range, when olanzapine is used in the intensive care setting. Finally, it is intriguing that the symptoms were reversed after administration of flumazenil, a selective competitive antagonist of the GABA receptor. Olanzapine mainly effects dopamine, serotonin, a1-adrenergic, histamine, and muscarinic receptors, but a low affinity to GABA and benzodiazepine sites can perhaps explain the observed effect." }, { "id": "pubmed23n0036_7665", "title": "[Sulpiride and drug addiction].", "score": 0.009900990099009901, "content": "The authors carried on their study as presented in Tunis Congress of Psychiatry and Neurology.

Two recent observations summarize the action of Sulpiride: 1. --A fit of acute depersonnalisation in a young lady was suppressed within eight days with the administration of 1 g p.o. of Sulpiride a day. Recovery without relapse. 2. --An old drug-addict would shoot himself i.v. with at least 1 g of Sulpiride whenever he wanted to stop his intoxication periods.

Naloxone is an opioid antagonist and reverses the central nervous depressive effects seen in opioid overdose. In the setting of a colonoscopy, naloxone is rarely administered but when it is administered, its half-life is shorter than some common opioid agonists. Therefore, the patient may still exhibit central nervous system depression after the naloxone has been cleared. Naloxone is typically administered in short intervals with relatively small doses in order to prevent the occurrence of withdrawal, pain, and sympathetic nervous system activation. Flumazenil is a benzodiazepine antagonist and blocks the binding of benzodiazepines to gamma-aminobutyric acid receptors. Similarly to naloxone, flumazenil has a short half-life, and this needs to be taken into account because the patient may exhibit central nervous depression after the antidote has been cleared.

The authors tested the hypothesis that mu-opioid receptor blockade by naloxone induces cardiovascular stimulation mediated by the sympathoadrenal system. Heart rate, cardiac index, and intravascular pressures were measured in 10 patients addicted to opioids (drug history; mean +/- SD, 71 +/- 51 months) during a program of methadone substitution (96 +/- 57 mg/day). Cardiovascular variables and concentrations of catecholamine in plasma were measured in the awake state, during methohexital-induced anesthesia (dose, 74 +/- 44 microg x kg(-1) x min(-1)) before administration of naloxone, and repeatedly during the first 3 h of mu-opioid receptor blockade. Naloxone was administered initially in an intravenous dose of 0.4 mg, followed by incremental bolus doses (0.8, 1.6, 3.2, and 6.4 mg) at 15-min intervals until a total dose of 12.4 mg had been administered within 60 min; administration was then continued by infusion (0.8 mg/h). Concentration of epinephrine in plasma increased 30-fold (15 +/- 9 to 458 +/- 304 pg/ml), whereas concentration of norepinephrine in plasma only increased to a minor extent (76 +/- 44 to 226 +/- 58 pg/ml, P &lt; 0.05). Cardiac index increased by 74% (2.7 +/- 0.41 to 4.7 +/- 1.7 min(-1) x m(-2)), because of increases in heart rate (89 +/- 16 to 108 +/- 17 beats/min) and stroke volume (+44%), reaching maximum 45 min after the initial injection of naloxone. In parallel, systemic vascular resistance index decreased (-40%). Systolic arterial pressure significantly increased (113 +/- 16 to 138 +/- 16 mmHg), whereas diastolic arterial pressure did not change. Despite barbiturate-induced anesthesia, acute mu-opioid receptor blockade in patients addicted to opioids induces profound epinephrine release and cardiovascular stimulation. These data suggest that long-term opioid receptor stimulation changes sympathoadrenal and cardiovascular function, which is acutely unmasked by mu-opioid receptor blockade. Because of the attendant cardiovascular stimulation, acute detoxification using naloxone should be performed by trained anesthesiologists or intensivists." }, { "id": "pubmed23n0274_21871", "title": "[Flumazenil, a benzodiazepine antagonist, in endoscopic premedication].", "score": 0.009615384615384616, "content": "Midazolam is the benzodiazepine recommended for anaesthesia induction when an early recovering is desirable.

This guideline does not substitute for clinical judgment. The grade of recommendation is in parentheses. 1) All patients with suicidal intent, intentional abuse, or in cases in which a malicious intent is suspected (e.g., child abuse or neglect) should be referred to an emergency department (Grade D). 2) Patients who exhibit more than mild effects (e.g., infrequent vomiting or somnolence [lightly sedated and arousable with speaking voice or light touch]) after an acute dextromethorphan ingestion should be referred to an emergency department (Grade C). 3) Patients who have ingested 5-7.5 mg/kg should receive poison center-initiated follow-up approximately every 2 hours for up to 4 hours after ingestion. Refer to an emergency department if more than mild symptoms develop (Grade D). 4) Patients who have ingested more than 7.5 mg/kg should be referred to an emergency department for evaluation (Grade C). 5) If the patient is taking other medications likely to interact with dextromethorphan and cause serotonin syndrome, such as monoamine oxidase inhibitors or selective serotonin reuptake inhibitors, poison center-initiated follow-up every 2 hours for 8 hours is recommended (Grade D). 6) Patients who are asymptomatic and more than 4 hours have elapsed since the time of ingestion can be observed at home (Grade C). 7) Do not induce emesis (Grade D). 8) Do not use activated charcoal at home.

Studies lasted for 2 to 3 months and a few had a follow up period up to a year. Olanzapine, dosed from 2.5 to 20 mg/day, is shown to be a useful drug in the treatment of child and adolescent onset schizophrenia, bipolar disorder, anorexia nervosa with delusions, pervasive developmental disorder, tic disorders, and aggression. OPEN AND DOUBLE-BLIND STUDIES: In 4 open labeled studies (26, 34, 39, 43) and 2 case reports (25), 53 patients, aged from 6-18 years old, afflicted by child onset schizophrenia, were treated with olanzapine for 1 1/2 weeks to one year; 19 had treatment resistant childhood schizophrenia and 34 a first episode. In the first group 13/19 showed improvement whereas, in the second group 27/34 were considered responders. Four patients in the first group who had responded to clozapine (stopped because of adverse events) did less well on olanzapine. In 5 studies, 4 open labeled (15, 20, 44) and 1 double blind (27), 59 adolescent onset schizophrenic patients were treated by olanzapine from 8 to 26 weeks; 50/59 patients were considered responders. In the open label study (20) comparing 43 adolescents treated by olanzapine (19 patients), risperidone (17 patients), or haloperidol (7 patients), improvement was significant in the three groups after 4 weeks of treatment and continued after 8 weeks. It is most interesting to mention that 2 months after the end of the study 71% (12/17) of the olanzapine group that had completed the study, 10/15 (67%) of the risperidone group, and 43% (3/7) of the haloperidol group had continued their treatment. Dropouts were for inefficacy and non-compliance in the olanzapine and risperidone groups whereas they were also for adverse events in the haloperidol group (2/4). A final double blind study of 263 adult and adolescent schizophrenic patients (latter are not separated from the former) confirmed the superiority of olanzapine compared to haloperidol and its use for a long period: 67% of the olanzapine and 54% of the haloperidol patients completed the 12-week study. 12 case reports of children and adolescents diagnosed with acute mania (8, 25, 46, 47) and 23 in an open labeled study (16) were treated by olanzapine; 26/35 were considered to respond well. Some of the patients were on mood stabilizers before adjunction of olanzapine, others on olanzapine monotherapy; 10 case reports of patients with anorexia nervosa associated with psychotic symptomatology, aged from 10-17 years old, relate the use of olanzapine as adjuvant treatment. Improvement was spectacular in these patients who not only gained considerable weight, but were also more compliant to the therapeutic program and their obsessions, delusions, agitation and anxiety became less intense. In this form of anorexia nervosa, olanzapine appears to have an interesting therapeutic role and, in particular, its most important adverse effect, weight gain, became a therapeutic goal. In 2 preliminary studies (24, 30) 31 children and adolescents diagnosed with pervasive developmental disorder were treated by olanzapine from 6 to 13 weeks; 18/25 had good or moderate symptomatic improvement: they were less irritable and hyperactive, and their speech less excessive. In 17 case reports of children and adolescents with aggression (42, 45), associated with tics in 10 patients (49), treatment with olanzapine from 2 weeks to 10 months lowered the presenting symptoms, enhanced the cooperation, and improved the mood of the patients. Only one patient's treatment was changed for inefficacy. No matter what the disorder treated, when olanzapine was compared to haloperidol and risperidone, it proved to be as effective as risperidone, and as or more effective than haloperidol; but when compared to clozapine, it was less effective. The most prominent adverse reaction was excessive weight gain, even more so than in adult patients treated with olanzapine. Also weight gain was greater in children and adolescents treated by olanzapine than those treated by risperidone or haloperidol. Though few treatments had to be interrupted because of this side effect, child and adolescent psychiatrists are wary of the long-term disease related to obesity and glucose dysregulation. All should be done to under-stand the process of weight gain better and to prevent or stall excessive caloric intake, encourage activity, and eventually treat by corrector drugs. Secondly, sedation may bother up to 50% of patients even at the end of the study periods, as many as those treated by haloperidol and more than those treated by risperidone. Extrapyramidal symptoms were mild or moderate compared to those that appear with haloperidol, but may be more frequent than in adult patients. Liver enzymes and blood sugar may be slightly elevated. Prolactemia may be elevated but less so with risperidone and haloperidol.

Endogenous benzodiazepine receptor ligands are thought to influence the human hypothalamic-pituitary-adrenal (HPA) axis and naloxone, a known stimulator of adrenocorticotropic hormone (ACTH) release, is thought to act via release of hypothalamic corticotropin-releasing hormone. 2. The aim of the present study was to assess the influence of endogenous benzodiazepine-receptor ligands by administering flumazenil (Ro15-1788), a benzodiazepine antagonist, and measuring ACTH and cortisol release, both basal and during naloxone-stimulation. 3. Nine normal volunteers in a placebo-controlled double-blind design were studied. Flumazenil (0.5 mg, i.v. bolus) was given 2 min before naloxone (125 micrograms/kg bodyweight, i.v. bolus) immunoreactive-adrenocorticotropic hormone (IR-ACTH) and cortisol levels were measured at frequent intervals from 60 min before to 120 min after naloxone injection. 4. Flumazenil had no effect on ACTH and cortisol release when given alone; flumazenil area under the ACTH/time curve (pmol/L.min) = -36.5 +/- 63.5 compared with placebo = -53.5 +/- 31.8, flumazenil area under the cortisol/time curve (nmol/L.min x 10(-3)) = - 2.4 +/- 2.4 compared with placebo -0.56 +/- 1.4. Flumazenil did not change the ACTH and cortisol release achieved with naloxone; naloxone area under the ACTH/time curve (pmol/L.min) = 327.8 +/- 61.7 compared with flumazenil/naloxone = 366.3 +/- 88.1, naloxone area under the cortisol/time curve (nmol/L. min x 10(-3) = 12.2 +/- 3.4 compared with naloxone/flumazenil = 10.5 +/- 2.1. 5. The authors conclude that flumazenil dose not modify basal or stimulated ACTH and cortisol release in healthy humans. This would suggest that endogenous benzodiazepine-like ligands and the benzodiazepine/gamma-aminobutyric acid receptor complex do not tonically influence the hypothalamic-pituitary-adrenal axis." }, { "id": "pubmed23n0308_9688", "title": "[Sedation in endoscopic diagnosis: rationale of the use of specific benzodiazepine antagonists].", "score": 0.008928571428571428, "content": "The aim of this study was to evaluate the best clinical use of Flumazenil, a specific antagonist of benzodiazepines, during endoscopic exams. Two-hundred patients were studied: 120 were treated with Flumazenil and 80 with placebo. The patients were prepared for the endoscopic exam with local anaesthesia and i.v. Diazepam administration. Controls performed at the end of the exam and at 5, 30, 120 e 240 minutes from the administration of Flumazenil and placebo, allowed to evaluate the state of awakeness, the level of conscience and the capacity of time-space orientation. Significantly statistical differences between the two groups were obtained at 5, 30 and 120 minutes after Flumazenil administration, while both groups had retrograde amnesia. The drug was well tolerated and there were no undesiderable side effects or reactions. The Authors therefore affirm that Flumazenil, in virtue of its competitive action toward benzodiazepine receptors, interrupts sedation with immediate awakening and improvement of the state of consciousness. Such drug, thus, permits the Day Hospital performance of endoscopic procedures which otherwise would require hospitalization, at the same time allowing the surgeon to use benzodiazepines at doses more adequate for surgical necessities." }, { "id": "pubmed23n1071_16139", "title": "Prompt improvement of difficulty with sleep initiation and waking up in the morning and daytime somnolence by combination therapy of suvorexant and ramelteon in delayed sleep-wake phase disorder: a case series of three patients.", "score": 0.008849557522123894, "content": "Patients with delayed sleep-wake phase disorder (DSWPD) suffer from difficulties in sleep initiation at night, difficulties in waking up at the socially required time, and daytime somnolence.

Recently, suvorexant, an orexin receptor antagonist, has become available for clinical use. The drug is relatively safer than traditional hypnotics such as benzodiazepines. We report three DSWPD patients who were successfully treated by the combination therapy of suvorexant and ramelteon. The first case was a 19-year-old woman who was experiencing difficulties in sleep initiation, difficulty in waking up in the morning, and daytime somnolence. She showed a prompt response to the combination therapy of suvorexant and ramelteon. Her sleep phase advanced, and her daytime somnolence reduced. The second and third cases were 21-year-old and 17-year-old men, respectively, who also showed significant sleep phase advances. Although case 2 was resistant to ramelteon treatment, his sleep phase advanced after suvorexant started. His difficulty in falling asleep and his habit of daytime napping disappeared after the combination therapy of suvorexant and ramelteon was started. Case 3 also showed a prompt response.

Patients were classified by clinical assessment (Killip) and into four hemodynamic subsets (HS) according to pulmonary capillary wedge pressure (PCWP) and cardiac index (CI) measures obtained by invasive central hemodynamic monitoring (Forrester): uncomplicated AMI, HS-I (PCWP less than or equal to 18 mmHg, CI greater than 2.2 L/min/m2) 15; pulmonary congestion, HS-II (PCWP greater than 18 mmHg, CI greater than 2.2 L/min/m2) 15; peripheral hypoperfusion, HS-III (PCWP less than or equal to 18 mmHg, CI less than or equal to 2.2 L/min/m2) 4; cardiogenic shock, HS-IV (PCWP greater than 18 mmHg, CI less than or equal to 2.2 L/min/m2) 6. Measurements taken within 48 hours after the onset of AMI showed significantly lower calf blood flow (p less than 0.05) and calf venous capacitance (p less than 0.01) and higher calf vascular resistance (p less than 0.05) in all AMI classifications compared to 10 normal subjects. In uncomplicated AMI group (Killip I and HS-I) calf blood flow and venous capacitance were significantly reduced while calf vascular resistance remained unchanged from normal. In AMI complicated by pulmonary congestion (Killip II and HS-II), in addition to reduced calf venous capacitance, calf blood flow was further significantly reduced (p less than 0.05) due, in part, to a rise in calf vascular resistance (p less than 0.05). In AMI complicated by severe heart failure and shock (Killip III, VI and HS-IV), mean changes in the periphery were not statistically different from those seen in patients with pulmonary congestion alone. In patients with AMI complicated by poor peripheral perfusion (HS-III), the peripheral changes did not show significant differences from those seen in uncomplicated AMI (HS-I).

We studied 25 patients with shock secondary to myocardial infarction successfully treated with percutaneous coronary intervention. Before the inclusion, 16 of 25 patients presented a cardiac arrest in the presence of medical staff. Norepinephrine was titrated to increase mean arterial pressure (MAP) from 65 to 85 mmHg during 1 h. Swan-Ganz variables, arterial and mixed venous blood gases, lactate, and thenar near-infrared spectroscopy variables (muscle tissue oxygen saturation [StO2] and its changes during a vascular occlusion test) were measured before, 1 h after norepinephrine uptitration, and 1 h after norepinephrine downtitration. To obtain a MAP at 85 mmHg, norepinephrine was increased from 0.6 (0.28-1.2) to 1.53 µg · kg · min (0.76-2.6 µg · kg · min) (P &lt; 0.00001) (median and interquartile range), with no change in heart rate.

Prospective cohort study. An ICU in a university hospital. Nineteen consecutive patients were admitted to the ICU for severe scorpion envenomation; all 19 patients exhibited hemodynamic pulmonary edema, and 10 patients had peripheral shock. All patients underwent a hemodynamic study with a Swan-Ganz catheter. In 8 of 19 patients, the thermodilution catheter was equipped with a fast-response thermistor. Standard hemodynamic parameters were recorded on admission and following the infusion of dobutamine in all patients at a dosage, from 7 to 20 microg/kg/min, intended to achieve the best hemodynamic and tissue oxygenation compromise. RV ejection fraction (RVEF) and RV volumes were simultaneously recorded in 8 patients, and tissue oxygenation parameters were assessed in the 10 patients with peripheral shock.

In 3 patients mean arterial pressure was greater than 80 mm Hg and cardiac index greater than 2.1 liters/min/m2 with normal mixed venous oxygen saturation despite simultaneous clinical shock. They recovered with no further treatment. Sixteen patients were treated with varying combinations of intravenous fluids and dobutamine (37 +/- 25 mu/kg/min) and 14 survived long enough for a second set of measurements to be completed. Mean heart rate increased from 83 +/- 22 to 101 +/- 20 beats/min and mean cardiac index from 1.4 +/- 0.5 to 2.5 +/- 0.4 liters/min/m2 (p less than 0.001). Oxygen consumption (VO2) was maintained even when oxygen delivery (DO2) was less than 330 ml/min/m2. After treatment DO2 increased from 230 +/- 69 to 397 +/- 60 ml/min/m2 (p less than 0.001) and VO2 from 103 +/- 31 to 124 +/- 27 ml/min/m2 (p less than 0.05).

Patients exclusions included: patients with cardiac pathology, not septic shock, pregnant, spontaneous breathing, increased intra-abdominal pressure, inferior vena cava could not be visualized, arrhythmia and pulmonary hypertension. Exclusion criteria for the study were as follows: 1) left ventricular systolic dysfunction, 2) cardiomyopathy, 3) medium severe heart valve disease, 4) patients with arrhythmia; 5) pulmonary hypertension, 6) patients without spontaneous breathing (for inferior vena cava collapsibility index, it is not evaluated), 7) patients with &gt;60 mmHg CO₂ in arterial blood gas; 8) pregnant patients; 9) patients with neurogenic shock, cerebrovascular incident or traumatic brain injury, 10) patients whose inferior vena cava and parasternal long axis cannot be visualized, and 11) patients with increased intra-abdominal pressure.

Accepted hemodynamic cutoffs are a cardiac index &lt; 2,2 (l/min)/m2 and a pulmonary capillary wedge pressure &gt; 15 mmHg. It should be acknowledged, that a normal blood pressure does not rule out CS; there is a nonhypotensive variant of CS demonstrating all the signs mentioned above (including elevated lactate levels) while the blood pressure is compensated due to vasoconstriction.The single most frequent cause of CS is pump failure in the setting of an acute myocardial infarction and its mortality rate has been lowered to 40-50%, owing to the widespread availability of primary PCI. Regarding PCI, it has been demonstrated recently that a \"culprit-lesion only strategy\" should be followed in the setting of CS. Other important causes of CS to take into account are mechanical complications of myocardial infarction (papillary and ventricular septal rupture as well as rupture of the myocardial free wall leading to tamponade), valvular heart disease (mostly decompensated aortic stenosis) as well as myocarditis and end stage cardiomyopathy.The diagnosis of CS is made by patient history, physical examination, ECG, echocardiography and coronary angiography. Echocardiography should always be performed before coronary angiography because, in the case of mechanical complications, it significantly alters the management of the patients. Patients with clinical signs of CS but paradoxically preserved ejection fraction must be thoroughly evaluated for the presence of a papillary muscle rupture, particularly in the setting of a lateral wall infarction.Noradrenaline and dobutamine are the first-line agents for medical stabilization. When such conventional measures fail, extracorporeal support devices such as ECMO or Impella© may be used.

CS was shown to develop more frequently in patients over 64 years of age, with a history of MI and with signs of chronic circulation insufficiency of IIA stage. Late CS more commonly took the true form and was associated with a MI relapse. Reflex CS was characterized by the hyperkinetic variant of the hemodynamics while an arrhythmic one by the congestive variant. Patients with the authentic form of CS were divided into 3 subgroups with different hemodynamic reactions to sympathomimetic amines.

His left ventricular end-diastolic pressure (LVEDP) was 24 mmHg and a left ventriculo-gram revealed a decrease in the left ventricular cavity in the apex and marked hypertrophy of the apical wall.

Case 1: A 24-year-old man had three relatives with HCM. At 13 years of age, he showed no electrocardiographic or echocardiographic abnormalities characteristic of HCM. During the ensuing 11 years, he developed asymmetric septal hypertrophy (ASH) and systolic anterior motion of the mitral valve (SAM), with right bundle branch block and T-wave inversion. Cardiac catheterization confirmed the diagnosis of hypertrophic obstructive cardiomyopathy by demonstrating an intraventricular pressure gradient of 25 mmHg. These observations indicate that this case developed abnormal hypertrophy during adolescence on the basis of genetic predisposition of an autosomal dominant trait. Case 2: A 51-year-old woman had three proven and three possibly affected relatives. At 35 years of age, she had a normal electrocardiogram, although the echocardiogram was not available. Now, 16 years later, she had developed ASH with abnormal Q-waves and was diagnosed as having non-obstructive HCM. These suggest that ASH can be manifested as late as during middle-age, even in those with genetic predisposition. Case 3: A 47-year-old woman was diagnosed as having hypertension and her blood pressure was 190/100 mmHg at 40 years of age, though she had no abnormal electrocardiographic findings and heart murmurs. Now, at 47 years of age, she had developed T-wave inversion, ASH, SAM, and an intraventricular pressure gradient of 50 mmHg. Thus, her ASH appeared during middle-age, and was probably provoked by hypertension, though a complete family survey could not be conducted. These three patients' findings indicate that there may be various modes of appearance of left ventricular hypertrophy in HCM. In the majority of patients with genetic predisposition, abnormal hypertrophy may develop during adolescence as in Case 1. In others, it may develop in middle-age, as it did in Case 2.

In the normal group, the blood flow velocity was 1.69 KHz in LVOT, and 1.71 KHz in RVOT. In AR and T/F but not MS, there was high blood flow velocity in the LVOT, and the peak of blood flow velocity was shifted to mid-to late systole. In ASD and VSD with a L-R shunt, high blood flow velocity occurred in the RVOT, and the peak velocity shifted to early systole. Pulmonary hypertension occasionally produced a W- or V-shaped curve.

The pulse could be regular, irregular, or irregularly irregular. Changes in the rate of the pulse, along with changes in respiration are called sinus arrhythmia. In sinus arrhythmia, the pulse rate becomes faster during inspiration and slows down during expiration. Irregularly irregular pattern is more commonly indicative of processes like atrial flutter or atrial fibrillation. We should also be checking for the radial and the femoral pulse simultaneously. If there is any delay between the pulses, it could indicate conditions like the coarctation of the aorta. Assessing the volume of the pulse is equally essential. A low volume pulse could be indicative of inadequate tissue perfusion; this can be a crucial indicator of indirect prediction of the systolic blood pressure of the patient. If we can palpate the radial pulse, the systolic blood pressure is generally more than 80 mmHg. If we can palpate the femoral pulse, the systolic blood pressure is more than 70 mmHg, and if we can palpate the carotid pulse, the systolic blood pressure is more than 60 mmHg. [10] Checking for symmetry of the pulses is important as asymmetrical pulses could be seen in conditions like aortic dissection, aortic coarctation, Takayasu arteritis, and subclavian steal syndrome. Besides the above-stated parameters, amplitude and rate of increase is also an important consideration.

Evolving technology and falling costs have demanded adaptation to clinical practice and implantation trends and, with the advent of evidenced-based medicine, the specific roles and benefits of individual pacemaker technologies have never been so carefully scrutinized. Pacing mode choice continues to be a subject of great controversy, and there are great regional variations in practice. We believe that single chamber atrial pacing use (AAI/R) has become an anachronism that should generally be abandoned (obviously with rare exceptional cases) and be replaced by dual chamber pacemakers (DDD/R) equipped with modern pacing algorithms that minimize patient exposure to ventricular pacing. Also, in patients with atrioventricular (AV) block, randomized clinical trials have failed to show improvement in clinically relevant outcomes such as mortality, stroke, and heart failure, particularly in the elderly, which has led some to advocate that DDD/R devices should never be offered to elderly AV block patients. However, we believe that the elderly, like the young, come in many \"shapes and sizes\" and individualized medicine compels us to consider each pacemaker candidate as unique. Implanting DDD/R devices in chronologically older, yet physiologically younger, patients is justifiable and good medical practice. Where right ventricular (RV) pacing is necessary and unavoidable, physicians should consider routinely placing RV leads on the RV mid- or outflow tract septum because these location are as good, if not better, for patients than the current practice of RV apical lead placement. In patients with AV block and asymptomatic yet moderate to severely depressed left ventricular systolic function, primary cardiac resynchronization therapy (CRT) should be strongly considered. Compelling clinical trial evidence does not yet exist to indicate that CRT should be the standard of care in patients with AV block and intact left ventricular systolic function.

An overview.", "score": 0.01838731443994602, "content": "Methods and devices for permanent cardiac pacing remained relatively stable for over two decades with use of the single-chamber ventricular demand (VVI) pacemaker. However, changes have occurred in the 1980s and are expected to continue with the availability of more advanced technology and with increasing knowledge about cardiac pacing. The physiologic benefit of the newer dual-chamber atrial synchronous (VDD) and fully automatic, universal (DDD) pacemakers over the VVI pacemaker in patients with permanent complete heart block and normal sinus node function has been established. These newer units not only reestablish atrioventricular synchrony but also are physiologically rate-responsive. The VDD pacemaker is expected to be phased out in favor of the DDD pacemaker. When the atrial rate or interval is lower than the lower rate limit, the VDD pacemaker functions as a VVI, whereas the DDD pacemaker functions as an atrioventricular sequential (DVI) pacemaker to maintain continuous atrioventricular synchrony. Contrary to general belief, patients with complete heart block and normal sinus node function may gain very little physiologic benefit, if any, from DVI pacing. The sinus node will compete with the pacemaker's atrial stimulation when the sinus rate is faster than the DVI pacemaker rate (which usually occurs during activity). Also, the ventricular pacing rate will not vary with physiologic change. The DVI and atrial demand (AAI) pacemakers have been used in some patients with sinus node dysfunction. Increasing exercise tolerance should not be expected in the majority of patients because they are not pacemaker-dependent during activity, ie, their heart rate is higher than the pacemaker rate. However, these pacemakers appear to help in eliminating pacemaker syndrome, which does not infrequently occur with VVI pacemakers. Patients with sinus node dysfunction but without atrioventricular block do not gain more physiologic benefit with a DDD than with a DVI pacemaker. Whether these patients have severe sinus node dysfunction all the time or adequate sinus node function most of the time during follow-up, the DDD pacemaker will function as a noncommitted DVI with atrial sensing (DDI). The early report of DVI pacemaker-induced atrial fibrillation during follow-up has been refuted by more recent works. If the DDD pacemaker is significantly more expensive than the DVI pacemaker, the latter type may be a good alternative for this condition." }, { "id": "pubmed23n0073_10456", "title": "[30 years cardiac pacemaker therapy: a status evaluation].", "score": 0.017494270435446907, "content": "Antibradycardiac pacemaker therapy has become established as one of the most effective forms of cardiological therapy for the indications AV-block, sick sinus syndrome, bradyarrhythmia, and hypersensitive carotid sinus.

For sick sinus syndrome, VVI-pacing proves to be a symptomatic measure, no prognostic importance can be proven. It is not conclusively clarified at present whether physiological pacing modes (AAI, DDD) have any such importance. Pacemaker therapy also has no prognostic importance for bradyarrhythmia. Hemodynamic importance: Numerous hemodynamic studies show that fixed-rate VVI-pacing fails to produce a long-term hemodynamic improvement for either an AV-block or a sick sinus syndrome. In sick sinus syndrome hemodynamic improvement can only be achieved by physiological pacing modes (AAI, DVI, DDD), whereby the increase in cardiac output is between 11% to 30%. For AV-block a long-term hemodynamic improvement can only be obtained by atrial triggered pacing modes (VAT, VDD, DDD); this is higher than the values of fixed-rate VVI-pacing by 7-25% at rest, or 10-40% under exercise.

Patients with sick sinus syndrome should receive an atrial (AAI) or dual-chamber (DDD) pacemaker, because patients with these in contrast to VVI-pacemakers develop less often atrial fibrillation and subsequent complications such as atrial thromboembolism. A dual-chamber or VDD-pacemaker--the latter connected to a VDD-single-lead--is indicated in patients with advanced AV-block. Atrial fibrillation occurs in 3 to 6% of the patients with no history of arrythmia and is, if pacemakers have no automatic mode switch, an often reason to program the devices to the VVI-pacing mode. Nowadays, most DDD(R)-pacemakers provide an automatic mode switch: During an atrial tachycardia the pacemaker switches to a VVI/VVIR mode and restores the initial DDD(R)-pacing mode with termination of the arrhythmia. In respect to the newer applications, one approach to prevent atrial tachyarrhythmias is permanent atrial pacing. As lower pacing rates of 80 to 90 ppm are usually needed and many patients hardly tolerate these pacing rates, new algorithms are under clinical investigation. Another approach is the simultaneous depolarization of the right and left atrium. Biatrial pacing is performed with one lead in the high right atrium and another lead in the coronary sinus. Another solution is bifocal atrial pacing with leads placed in the high right atrium and in the coronary sinus ostium. One effect of the new pacing techniques is to shorten interatrial conduction times. Therefore, biatrial pacing has become a therapy to prevent atrial arrhythmias deriving from delayed interatrial conduction times. As atrial reentry circuits seem to be important in atrial fibrillation, multisite atrial pacing is also performed in patients with medical refractory paroxysmal atrial fibrillation. Preliminary results suggest a more effective prevention of atrial fibrillation; nevertheless, these techniques should be still restricted to patients enrolled in clinical studies." }, { "id": "pubmed23n0658_1651", "title": "[Retrospective analysis of 1650 permanent pacemaker implantations experience over two different consecutive time periods in a single cardiology clinic].", "score": 0.015756302521008403, "content": "Indications for pacing, pacing modes, and demographics of patients who underwent pacemaker implantation between two different time periods were compared in this study.

RV pacing was linked with left ventricular (LV) dyssynchrony in almost 50% of patients with PM implantation and atrioventricular (AV) node ablation for AFib. In patients with normal systolic function needing a PM, apical RV pacing resulted in LV ejection fraction (LVEF) reduction. These negative effects were prevented by cardiac resynchronization therapy (CRT). Algorithms favoring physiological AV conduction are possible useful tools able to maintain both atrial and ventricular support and limit RV pacing. However, when chronic RV pacing cannot be avoided, it appears necessary to reconsider the cut-off value of basic LVEF for CRT. In HF patients, RV pacing can induce greater LV dyssynchrony, enhanced by underlying conduction diseases. In this context, a more deleterious effect of RV pacing in implantable cardioverter-defibrillator (ICD) patients with low LVEF can be expected. In some major ICD trials, DDD mode was correlated with increased mortality/HF. This negative impact was attributed to unnecessary RV pacing &gt;40-50%, virtually absent in VVI-40 mode. However, some data suggest that avoiding RV pacing may also not be the best option for patients requiring an ICD. In patients with impaired LV function, AV synchrony should therefore be ensured.

We compared the results with those of fundamental S‑ICD studies and tried to determine risk factors on the basis of medical history and pre-implant data. The study population and the rate of endpoints were significantly different to those of fundamental S‑ICD studies. Within a 2.2-year follow-up, 14.9 % of the patients developed a need for pacemaker stimulation and 0.8 % the need for cardiac resynchronization. Excluding patients who at implantation were already at high risk for pacemaker dependency, 7.4 % remained with a reached endpoint. We identified atrial fibrillation and bundle-branch-block as risk factors. All episodes of ventricular tachycardia (VT) could be terminated by ATP in 9.9 % of the patients. They more often had ischemic heart disease and a secondary prophylactic indication for an ICD. The low rate of conversions from S‑ICD to a transvenous ICD in case of pacemaker-dependency as stated in fundamental S‑ICD studies should not be transferred to other typical collectives of ICD recipients.

We are faced with a situation of probable liver metastasis from a localized colon adenocarcinoma treated 2 years ago. Probable because we do not have histological confirmation, although as it usually happens, what else could it be? As this is a situation of oligometastasis and the treatments for advanced colon adenocarcinoma allow prolonged survival with good quality of life in these patients, if there is nothing to contraindicate surgery, this should be the first option (correct answer 3). I attach the algorithm proposed by the NCCN in situations of recurrence (http://www.nccn.org/professionals/physician_gls/pdf/colon.pdf). In case of an unresectable situation, chemotherapy treatment would be considered with the intention of converting the single metastatic lesion into a resectable one. Since more than 12 months have passed since FOLFOX treatment, the same scheme could be used, although FOLFIRI+bevacizumab would also be useful. Capecitabine monotherapy, in the patient's current situation, would also not be a good starting option, since the responses are lower compared to FOLFOX or FOLFIRI plus antiangiogenic combinations. Hepatic radiotherapy could be considered, since there are SBRT techniques that achieve very good results, but in this case it is best to start by asking for an assessment by the surgeons and if they rule out surgery we would consider RT.

A 57-year-old patient diagnosed with stage T3N1M0 adenocarcinoma of the colon. He was treated with resection followed by postoperative FOLFOX chemotherapy (fluorouracil, leucovorin and oxaliplatin) for 6 months. In a routine control, two years later, carcinoembryonic antigen (CEA) elevation to 30 ng/mL (previously less than 2 ng/mL) was detected. She has no symptoms, physical examination is unremarkable, chest X-ray is normal. CT scan shows a 3 cm mass in the right hepatic lobe that is captured on PET. No other alterations are observed in CT or PET. What is the most correct approach?

We retrospectively evaluated the diagnostic performance of FDG-PET/CT in patients with suspected recurrence of CRC by comparing PET/CT performance in patients with normal CEA levels with PET/CT performance in patients with elevated CEA levels. A total of 235 patients with CRC who had been treated with surgery and/or chemotherapy/radiotherapy underwent PET/CT for the detection of tumor recurrence. The patients [96 females and 139 males; age (mean ± SD) 59.9 ± 12.6 years; range 18-85] were divided into 2 groups based on whether their CEA levels were normal (&lt;5 ng/ml) (Group 1, n = 118) or elevated (&gt;5 ng/ml) (Group 2, n = 117). All of the patients had suspected recurrence based on raised CEA levels, clinical symptoms, and/or tumor detection using other imaging modalities. Of the 235 patients, 172 (73.1 %) had disease recurrence confirmed by a pathological examination (either biopsy or surgical exploration) or clinical follow-up studies. The FDG-PET/CT study yielded a true positive in detecting recurrence in 169 (71.9 %) patients, a true negative in 53 (22.5 %) patients, a false negative in 3 (1.2 %) patients and a false positive in 10 (4.2 %) patients.

The specificity and sensitivity of increases in CEA before finding recurrent disease were calculated by receiver operating characteristic (ROC) curves. An economic evaluation of the cost per resectable tumor recurrence was performed. ROC curves showed that a significant CEA increase was defined as a 25 % increase from the previous value. Recurrences were detected in 46 % of the procedures through CEA increase concomitant with positive imaging, in 23 % through CEA increase without positive findings on routine imaging, and in 31 % through positive imaging without an increase in CEA. The resectability of recurrences did not differ between triggers. Cost per curable recurrence was &lt;euro&gt;2,196 for recurrences found via CEA alone and &lt;euro&gt;6,721 for recurrences found with imaging and CEA.

In March 2017, a 47-year-old female was diagnosed with rectal cancer and synchronous liver metastases, microsatellite stability, and Kras mutation. The patient received folinic acid, fluorouracil, and oxaliplatin (FOLFOX) chemotherapy, with good response and a decrease in tumor markers. After chemotherapy, a computed tomography (CT) scan showed one lesion located on the right liver with lateral invasion of the vena cava, and another lesion located in segment I. A liver-first strategy was decided and, in October 2017, the patient had a right hepatectomy extended to segment I and partially on the diaphragm, with lateral resection of the vena cava under isolated clampage of the vena cava and reconstruction with a peritoneal graft (60 mm). The patient received FOLFOX adjuvant chemotherapy for 3 months, and, while under radiotherapy for the rectal cancer, recurrence was diagnosed on the left liver lobe (two lesions), with lateral invasion of the left hepatic vein. Chemotherapy was shifted to folinic acid, fluorouracil, and irinotecan (FOLFIRI)-Avastin, with good response, allowing resection of the primary (T3N0M1), followed by adjuvant chemotherapy. In May 2019, the patient underwent two large resections on the left liver, including one under TVE, with opening of the diaphragm and intrathoracic control of the vena cava. The left hepatic vein was reconstructed laterally with a peritoneal graft (30 mm). Postoperative outcome was uneventful and the two hospital stays were 12 and 15 days, respectively. For the first hepatectomy, pathological examination showed two lesions (80 and 50 mm) with a residual tumor at 10% and R0 resection, and, for the second resection, pathological examination showed two lesions (18 and 20 mm) with residual tumor at 40-60% and R0 resection. In both cases, the tumor was in contact with the resected vein without wall infiltration. The reconstructed vena cava and hepatic vein were patent without stenosis. The patient is disease-free 3 years after the diagnosis. Improvements in surgical technique combined with short TVE and associated thoracotomy allow some complicated liver resections to be performed safely.

Since there exists no generally accepted modality to assess CEA curves of patients receiving chemotherapy, we developed our own criterion and tested it in a group of 35 patients. For each patient an individual reference level (CEA-means) was fixed which was obtained as the arithmetical mean of serial CEA values taken during the first three courses of chemotherapy (reference time). On the basis of CEA-means the marker curves of the 35 patients could be divided into two groups. After the reference time the CEA values of group 1 (12 patients) never decreased below CEA-means. Survival of these patients was significantly (P = 0.00001) shorter than that of the 23 patients (group 2) who showed a decrease in their CEA curves below CEA-means after the reference time. Beyond this it could be observed that the improvement in survival was significantly greater in those patients who showed a CEA decrease below CEA-means for a prolonged period (3 months). This difference in prognosis is not an artefact due to different pretherapeutic conditions but is a sign of different responses to therapy. The decrease in CEA values below the individual reference level (CEA-means) is a certain sign of the efficacy of the chosen chemotherapy.

Our objective was to determine any association between the preoperative level of CEA and prognosis, and the resectability and survival by method of diagnosis of colorectal hepatic metastases. We analyzed patients who underwent exploration for hepatic resection for metastatic colorectal cancer over a 15-year period. The patient population consisted of those patients who had undergone primary colon or rectal resection and were followed up with serial CEA levels and of patients who were followed up with physical examination, liver function tests (LFTs) or computed tomography (CT) of the abdomen and pelvis that led to the diagnosis of liver metastases. Also included in the study were patients who were diagnosed with liver metastases at the time of the primary colon or rectal resection and underwent planned hepatic resection at a later time. Three hundred and one (301) patients who underwent a total of 345 planned hepatic resections for metastatic colorectal cancer between January 1978 and December 1993 were included in this analysis. The median preoperative CEA level was 24.8 ng/mL in the resected group, 53.0 ng/mL in the incomplete resection group, and 49.1 ng/mL in the nonresected group (P = 0.02).

The resectability rate and the survival of patients by method of diagnosing liver metastases-rising CEA versus history and physical, elevated LFTs, CT scan versus diagnosis at the time of primary resection-was not significant (P = 0.06 and P = 0.19, respectively). Given the nonstandardized retrospective nature of the study cohort and relative small groups of patients, the power to detect small differences in survival by method of diagnosis is limited. In the complete resection group of patients with unilobar liver disease (5-year survival of 28.8%) there was no difference in survival between those patients who had normal preoperative CEA and those who had elevated preoperative CEA, and approximately 90% of them had an abnormal preoperative serum CEA level. CEA is useful in the preoperative evaluation of patients with hepatic colorectal metastases for assessing prognosis and is complimentary to history and physical examination in the diagnosis of liver metastases.

FDG PET imaging is valuable for differentiation of posttreatment changes from recurrent tumor, differentiation of benign from malignant lesions (indeterminate lymph nodes, hepatic and pulmonary lesions), and evaluation of patients with rising tumor markers in the absence of a known source. Addition of FDG PET to the evaluation of these patients reduces overall treatment costs by accurately identifying patients who will and will not benefit from surgical procedures. Although initial staging at the time of diagnosis is often performed during colectomy, FDG PET imaging is recommended for a subgroup of patients at high risk (with elevated CEA levels) and normal CT and for whom surgery can be avoided if FDG PET shows metastases.

The ORR was 17% in the FOLFOX group versus 36% in the FOLFIRI group (p=0.22). This difference was not statistically significant, despite a trend in favor of FOLFIRI. Metastatic disease after exposure to oxaliplatin in the adjuvant setting tends to occur early and can be characterized by partial resistance to this agent.

Delivery of i.v. drugs can be enhanced by an i.v. flush of sodium chloride. In endotracheal drug administration, higher doses and drug dilution are recommended. In infants and children up to 6 years of age, the value of intraosseous drug administration is emphasized. For pulseless adult victims, the initial dosage of epinephrine of 1 mg i.v. remains unchanged. For repeat doses, high-dose epinephrine up to 0.1 mg/kg is classified as of uncertain but possible efficacy. For lidocaine, the recommended i.v. dosage is 1.5 mg/kg. Sodium bicarbonate and calcium are not routinely recommended for resuscitation. For atropine, the maximum dose is 0.04 mg/kg. If hypomagnesaemia is present in recurrent and refractory ventricular fibrillation, it should be corrected by administration of 1 to 2 g magnesium sulfate i.v. Thrombolytic agents are classified as useful and effective in acute myocardial infarction and should be administered as early as possible.

During the therapy the patient was given basically without any changes a combination of mineral solution Plasma-Lyte 148, amino-acid and 20% glucose. During 8 days a serious metabolic alkalosis had developed (caused by a lack of chlorides, phosphates and other reasons), combined with respirational acidosis. Hydrogencarbonate level was increased to 47.2 mmo/l (at norm of 24 mmol/l), base excess level to 21.4 mmol/l (at norm of 0 mmol/l). Metabolic acidosis led to reduction of sensibility of the respiratory centers and therefore it was not possible to restore spontaneous respiration. After the therapy change and reduction of metabolic acidosis the state of the patient got better. Application of acidifying solutions, supplementation of phosphate and potassium levels and replenishment of actual losses of phosphates led to regulation of the inner environment. Together with the application of sufficient amount of basic nutrients was the improvement of acid-base balance the key factor which enabled the restoration of spontaneous respiration and disconnection of the patient from the ventilator.

Because you've read this article, you know that the patient's smoking habit and the city's elevation can affect the pulse oximeter's accuracy, leading one to underestimate the severity of the problem.

A diagnosis of life-threatening inadequate oxygenation is supported by which of the following astute observations: a) An abnormal base deficit is proven by the borderline acidic pH and the low PaCO2. b) His anemia reduces both his buffer base and his oxygen carrying capacity. c) His hypothermia overstates his PO2 because the blood was heated up before measurement. d) His smoking makes a CO level likely, worsening his anemia and ignored by the pulse oximeter. e) The high level of supplemental oxygen has minimal effect on his arterial oxygen tension, showing severe pulmonary gas transfer problems (shunting). f) The measurement of his PaO2 is artificially high because he is at altitude.

In this report, we retrospectively investigated the effect of OHP on sudden deafness. We reviewed 522 patients treated with OHP at Kagawa Rosai Hospital over a ten-year period (January 1989 to December 1998). We discussed some prognostic factors: comparison between cases which had been treated with OHP previously and those which had not, number of days between onset and beginning of the treatment which included OHP, age, initial averaged five-frequency hearing level, vertigo, tinnitus, complications of OHP, cases of relapse and the time of the onset, which is about season, month and week. OHP was administered at a pressure of 2.5 atmospheres for 80 minutes a day from 10 to 15 times. All patients also received a course of intravenous administration of steroid, vitamin B12, Prostaglandin E1, ATP, and low-molecular dextran. Overall, complete recovery occurred in 19.7% of the patients, definite improvement in 34.9% (complete recovery included), and slight improvement in 58.1% (definite improvement included). Most of the patients (78.0%) were referred by other hospitals, because our hospital was the only one in the Sikoku area which had a big equipment of OHP. All 161 patients had already been treated in other hospitals over 8 days, but they had shown little improvement after the initial therapy. Of this group, complete recovery after the second course of treatment occurred in 13.0% of the patients, definite improvement in 19.3%, and slight improvement in 39.1%. OHP was thus effective for about 40% of patients who had been unresponsive to the initial therapy. Delay in treatment usually produces poor hearing recovery. There was a significant difference between those patients treated within 14 days and those treated 15 days or more after onset. The improvement rate also decreased with age. The prognosis of patients with vertigo was worse than those without vertigo. Tinnitus had no influence on the prognosis. There were no severe complications during the course of OHP, but otitis media with effusion occurred in 90 patients, and paracentesis was performed for 53 patients. The treatment of sudden deafness with OHP has been discussed in this report. Important prognostic factors were time between onset and beginning of the treatment which included OHP, age, vertigo, and the initial averaged five-frequency hearing level.

Hypertonic sodium (HS) solutions have been advocated for resuscitation from hemorrhagic shock (small volume resuscitation). As hypertonic fluids may also be of interest in cardiac surgery, the effects of a new HS solution were studied. METHODS. In 90 patients undergoing aorto-coronary bypass grafting studies were performed at three different periods: I (n = 30) after induction of anesthesia (before onset of the operation); II (n = 30) during cardiopulmonary bypass (CPB); III (n = 30) after termination of bypass. During these periods the patients were randomly allocated to one of three groups with 10 patients in each group: group 1 received a new hypertonic solution prepared in hydroxyethyl starch (HES) solution (72 g/l NaCl, 60 g/l HES, 2400 mosmol/l; HS-HES patients), group 2 received a 6% HES solution (200/0.5; HES patients), and group 3 received no volume infusion and served as controls. RESULTS. After the induction of anesthesia, significantly less HS-HES solution (4.5 +/- 0.5 ml/kg) than 6% HES solution (10.1 +/- 1.4 ml/kg) was necessary to double the baseline PCWP. The fluid balance during CPB was negative in the patients who had received HS-HES preoperatively (-0.03 +/- 0.01 ml/kg.min CPB), whereas 6% HES (+0.06 +/- 0.02 ml/kg.min CPB) and control patients (+0.13 +/- 0.03 ml/kg.min CPB) had a positive fluid balance. Both after the induction of anesthesia and after termination of bypass, CI increased more in the HS-HES group than in the HES patients, and it even decreased in the control group. SVR decreased in the HS-HES patients, whereas it increased in the control group. Rapid infusion of HS-HES during CPB was followed by a significant, but short-lasting decrease in MAP (-40 mmHg) and an increase in the oxygenator volume. Pulmonary gas exchange (= paO2) was least compromised in the HS-HES patients; the sodium concentration increased only in the HS-HES patients, but never exceeded 150 mmol/l. DISCUSSION. Cardiac surgery procedures offer a special situation for volume therapy as there is a possibility of deterioration in the macro- and microcirculation before, after, and during the period of CPB. Hemodynamic effects of the new HS-HES solution included an increase in CI and a decrease in SVR, which were not merely transient as has been reported which hypertonic saline solution used alone. It was also observed that HS-HES patients required significantly smaller volumes of fluids, both during CPB and during the early postoperative period. This effect seems to be due to a redistribution of interstitial fluid to the intravascular space, possibly decreasing tissue edema. CONCLUSION. The hypertonic saline HES solution adds a new dimension to volume therapy for cardiac surgery patients. The improvement in hemodynamics was effective and not only transient. Fluid requirements were significantly reduced during as well as after CPB, and pulmonary gas exchange was least compromised in these patients." }, { "id": "pubmed23n0853_11905", "title": "[Effect of 3% hypertonic saline as early fluid resuscitation in pediatric septic shock].", "score": 0.009009009009009009, "content": "The mainstay of therapy in patients with septic shock is early and aggressive intravenous fluid resuscitation.

This subsequently increased to 14.3% (16 h after OHCob administration) and peaked at 16.3% (47 h after OHCob administration), at which time he was administered a dose of methylene blue 50 mg i.v., 60 h after ED arrival. His methemoglobin concentrations fluctuated until a consistent downward trend starting at 92 h from ED arrival. He continued to deteriorate and expired on hospital day 5 with a methemoglobin concentration of approximately 6.0%. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: CN toxicity requires immediate recognition and treatment. The antidote, OHCob, is believed to not induce methemoglobinemia. However, this potential side effect must be considered by emergency physicians when treating suspected CN toxicity, especially if the patient does not improve after antidotal therapy." }, { "id": "pubmed23n0680_16690", "title": "[Comments on the 2010 guidelines on cardiopulmonary resuscitation of the European Resuscitation Council].", "score": 0.008928571428571428, "content": "Administer chest compressions (minimum 100/min, minimum 5 cm depth) at a ratio of 30:2 with ventilation (tidal volume 500-600 ml, inspiration time 1 s, F(I)O₂ if possible 1.0). Avoid any interruptions in chest compressions. After every single defibrillation attempt (initially biphasic 120-200 J, monophasic 360 J, subsequently with the respective highest energy), chest compressions are initiated again immediately for 2 min independent of the ECG rhythm. Tracheal intubation is the optimal method for securing the airway during resuscitation but should be performed only by experienced airway management providers. Laryngoscopy is performed during ongoing chest compressions; interruption of chest compressions for a maximum of 10 s to pass the tube through the vocal cords. Supraglottic airway devices are alternatives to tracheal intubation. Drug administration routes for adults and children: first choice i.v., second choice intraosseous (i.o.). Vasopressors: 1 mg epinephrine every 3-5 min i.v. After the third unsuccessful defibrillation amiodarone (300 mg i.v.), repetition (150 mg) possible. Sodium bicarbonate (50 ml 8.4%) only for excessive hyperkaliemia, metabolic acidosis, or intoxication with tricyclic antidepressants. Consider aminophylline (5 mg/kgBW). Thrombolysis during spontaneous circulation only for myocardial infarction or massive pulmonary embolism; during on-going cardiopulmonary resuscitation (CPR) only when indications of massive pulmonary embolism. Active compression-decompression (ACD-CPR) and inspiratory threshold valve (ITV-CPR) are not superior to good standard CPR. Most effective improvement of outcome by prevention of full cardiorespiratory arrest. Basic life support: initially five rescue breaths, followed by chest compressions (100-120/min depth about one third of chest diameter), compression-ventilation ratio 15:2. Foreign body airway obstruction with insufficient cough: alternate back blows and chest compressions (infants), or abdominal compressions (children &gt;1 year). Treatment of potentially reversible causes: (\"4 Hs and 4 Ts\") hypoxia and hypovolaemia, hypokalaemia and hyperkalaemia, hypothermia, and tension pneumothorax, tamponade, toxic/therapeutic disturbances, thrombosis (coronary/pulmonary). Advanced life support: adrenaline (epinephrine) 10 µg/kgBW i.v. or i.o. every 3-5 min. Defibrillation (4 J/kgBW; monophasic or biphasic) followed by 2 min CPR, then ECG and pulse check. NEWBORNS: Initially inflate the lungs with bag-valve mask ventilation (p(AW) 20-40 cmH₂O). If heart rate remains &lt;60/min, start chest compressions (120 chest compressions/min) and ventilation with a ratio 3:1. Maintain normothermia in preterm babies by covering them with foodgrade plastic wrap or similar. POSTRESUSCITATION PHASE: Early protocol-based intensive care stabilization; initiate mild hypothermia early regardless of initial cardiac rhythm [32-34°C for 12-24 h (adults) or 24 h (children); slow rewarming (&lt;0.5°C/h)]. Consider percutaneous coronary intervention (PCI) in patients with presumed cardiac ischemia. Prediction of CPR outcome is not possible at the scene, determine neurological outcome &lt;72 h after cardiac arrest with somatosensory evoked potentials, biochemical tests and neurological examination. ACUTE CORONARY SYNDROME: Even if only a weak suspicion of an acute coronary syndrome is present, record a prehospital 12-lead ECG. In parallel to pain therapy, administer aspirin (160-325 mg p.o. or i.v.) and clopidogrel (75-600 mg depending on strategy); in ST-elevation myocardial infarction (STEMI) and planned PCI also prasugrel (60 mg p.o.). Antithrombins, such as heparin (60 IU/kgBW, max. 4000 IU), enoxaparin, bivalirudin or fondaparinux depending on the diagnosis (STEMI or non-STEMI-ACS) and the planned therapeutic strategy. In STEMI define reperfusion strategy depending on duration of symptoms until PCI, age and location of infarction. TRAUMA: In severe hemorrhagic shock, definitive control of bleeding is the most important goal. For successful CPR of trauma patients a minimal intravascular volume status and management of hypoxia are essential. Aggressive fluid resuscitation, hyperventilation and excessive ventilation pressure may impair outcome in patients with severe hemorrhagic shock. Any CPR training is better than nothing; simplification of contents and processes is the main aim." }, { "id": "pubmed23n0478_12215", "title": "[Haemodynamic effects following preoperative hypervolemic haemodilution with hypertonic hyperoncotic colloid solutions in coronary artery bypass graft surgery].", "score": 0.008878048780487806, "content": "Using hyperoncotic colloids as volume replacement to provide haemodynamic stability appears to be a suitable approach to diminish fluid overload and subsequent interstitial edema during cardiac surgery. The aim of the present study was to investigate for the first time the haemodynamic effects following preoperative haemodilution with different hypertonic hyperoncotic colloid solutions in patients undergoing coronary artery bypass grafting. A total of 43 patients with normal left ventricular ejection fraction, undergoing elective coronary artery bypass grafting received preoperatively after induction of anaesthesia according to randomisation the following solutions: 1: 750 ml/m(2) (body surface area) NaCl 0.9% ( n=10, control group, NACL), 2: 250 ml/m(2) 10% HES 200/0.5 plus 400 ml/m(2) NaCl 0.9% ( n=9, HES), 3: 250 ml/m(2) 10% dextran 40 plus 300 ml/m(2) NaCl 0.9% ( n=8, DEX), 4: 150 ml/m(2) hypertonic NaCl (7.2%) 10% HES 200/0.5 (n=8, HYPER-HES), 5: 150 ml/m(2) hypertonic NaCl (7.2%) 10% dextran 60 ( n=8, HYPER-DEX). Haemodynamic measurements were performed immediately before and 15 min after haemodilution and up to 60 min after termination of extracorporeal circulation in 10 min intervals. Fluid balances were calculated separately, during the time period of surgery, postoperatively up to 24 h after termination of surgery, and during the course of extracorporeal circulation. After haemodilution with colloid solutions, a marked increase was observed in all patients and with HYPER-HES and HYPER-DEX a statistically significant increase in cardiac index (CI: +38%, +54%), stroke volume index (SVI: +42%, +40%), and oxygen availability (DO2: +34%; +41%), respectively, was observed during the pre-bypass period. At the same time right and left ventricular filling pressures increased slightly in all patients but these changes did not differ among the treatment groups. Heart rate and mean arterial pressure remained almost unchanged in all groups. The amount of crystalloid solutions required by the patients during surgery was markedly decreased with HES and DEX and significantly decreased with HYPER-HES and HYPER-DEX (1,013+/-341 ml/m(2), 1,096+/-234 ml/m(2)) compared to the control group NACL (1629+/-426 ml/m(2)). Serum sodium concentrations increased with HYPER-HES and HYPER-DEX to maximal values of 150+/-3 mmol/l and 149+/-4 mmol/l, respectively (baseline 141+/-3 mmol/l, 141+/-1 mmol/l) Compared to isotonic saline solution, preoperative volume replacement with hyperoncotic colloids improves haemodynamic conditions during the pre-bypass period in patients with normal left ventricular function undergoing coronary artery bypass grafting. Additionally intraoperative crystalloid solution requirements are reduced. The volume saving effects are increased with administration of hyperoncotic colloids in a preparation with hypertonic saline solution, whereas the choice of the colloid, either hydroxyethyl starch or dextran seems to be of minor importance." }, { "id": "wiki20220301en478_888", "title": "Hyperbaric treatment schedules", "score": 0.008849557522123894, "content": "Built in breathing system Treatment gases are generally oxygen or oxygen rich mixtures which would constitute an unacceptable fire hazard if used as the chamber gas.

As a potent antimicrobial, it has activity against methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus, penicillin-resistant Streptococcus pneumoniae, and macrolide-resistant streptococci. There are several documented case reports of serotonin toxicity when used with selective serotonin reuptake inhibitors. The symptoms of serotonin syndrome are alteration of mental state, autonomic dysfunction, and neuromuscular disorders. This article presents a case of an interaction of the serotonin reuptake inhibitor venlafaxine and linezolid and the possible diagnostic problems that can occur. A 58-year-old woman presented with signs of systemic infection. Her medical history included bladder resection for transitional cell carcinoma, bilateral total hip arthroplasty (THA), and depression, for which she was on venlafaxine. Serological and imaging investigations revealed MRSA infection of the bilateral THA. The patient was started on vancomycin and rifampicin intravenously. As intravenous access was becoming problematic and long-term antibiotics were needed, treatment was changed to oral linezolid and oral rifampicin. Four days after the commencement of linezolid, the patient was acutely disorientated with generalized cerebellar signs and no autonomic dysfunction. A computed tomography scan of the head and lumbar puncture revealed no abnormal findings. A diagnosis of serotonin toxicity was made. The patient recovered when linezolid and venlafaxine were discontinued and supportive measures were provided. Linezolid is a popular choice of antibiotic, especially for the treatment of orthopedic-related MRSA infections. Patients who commonly require linezolid as an antimicrobial are those with complex infections where other antibiotic treatment has failed. It is therefore important to be vigilant with linezolid use. Physicians should be aware of the nonspecific presentation of serotonin symptoms and the treatment." }, { "id": "pubmed23n0689_16720", "title": "Linezolid interaction with serotonin reuptake inhibitors: report of two cases and incidence assessment.", "score": 0.015936507936507936, "content": "Prompted by the advent of potentially life-threatening neuromuscular symptoms following initiation of linezolid therapy in two patients receiving treatment with a serotonin reuptake inhibitor antidepressant, an evaluation was conducted to determine the incidence and characteristics of symptomatic serotonin toxicity among hospitalized patients receiving combined treatment with these medications. Patients admitted between January 1, 2006 and August 30, 2008 who received linezolid concurrently with citalopram or escitalopram were identified and their medical records were examined. Patients were judged to have serotonin toxicity if their records contained documentation of clinical evidence adequate to fulfill requisites of the Hunter Serotonin Toxicity Criteria. Severity of serotonin-related symptoms was graded according to previously established criteria. During the period of observation, 24 patients received concurrent treatment with linezolid and citalopram or escitalopram. Of these, one patient (4%) treated with citalopram met evidentiary requirements for diagnosis of serotonin toxicity. The severity of symptoms in this patient was graded as mild. No evidence of serious harm related to a possible drug interaction was identified. Severe symptoms associated with serotonin toxicity were shown to be uncommon in patients receiving linezolid and selected serotonin reuptake inhibitors. Nonetheless, serious interaction-related toxicity has been observed at our institution and reported in detail by others. Accordingly, concurrent use of these medications is categorized as contraindicated. Alternative antimicrobial therapy should be instituted in most cases.

Several cases of serotonin syndrome in patients taking linezolid and SSRIs have been reported, including two reports with sertraline, one with paroxetine, four with citalopram, and two with fluoxetine. One abstract of a retrospective analysis reported that serotonin syndrome did not occur in patients who received linezolid and fluoxetine, paroxetine, or sertraline. Because of several limitations, however, no conclusions can be drawn from that retrospective analysis. A drug interaction involving escitalopram and linezolid has not been documented. Caution should be used when linezolid is used in patients receiving an SSRI. Other antibiotic options should be considered first, and linezolid should be reserved as the last resort if possible.

More severe symptoms include fever, seizures, irregular heartbeat, delirium, and coma. If signs or symptoms arise, discontinue treatment with serotonergic agents immediately. It is recommended to washout 4 to 5 half-lives of the serotonergic agent before using an MAO inhibitor." }, { "id": "pubmed23n0835_11779", "title": "Linezolid-Associated Serotonin Syndrome.

Use of linezolid has been associated with serotonin syndrome, a potentially life-threatening condition typically caused by the combination of two or more medications with serotonergic properties, due to increased serotonin release. The goals of this article are to highlight the risk factors associated with the development of serotonin syndrome related to the use of linezolid and to aid in its prevention and early diagnosis. In this case series we report on two hospitalized patients who, while being treated with linezolid for pedal infections, developed serotonin syndrome. Both individuals were also undergoing treatment with at least one serotonergic agent for depression and had received this medication within 2 weeks of starting the antibiotic drug therapy. In these individuals, we noted agitation, confusion, tremors, and tachycardia within a few days of initiation of linezolid therapy. Owing to the risk of serotonin toxicity, care should be taken when prescribing linezolid in conjunction with any other serotonergic agent. Although serotonin syndrome is an infrequent complication, it can be potentially life threatening. Therefore, risks and benefits of therapy should be weighed before use.

More recently, Corynebacterium striatum has been implicated in human infections, including respiratory infections, endocarditis, and bone and joint infections, particularly those involving hardware or implanted devices. A 65-year-old man presented for washout of his left total knee arthroplasty following a revision 20 days prior. The patient underwent debridement of his left total knee and revision of the left total femur arthroplasty. Daptomycin was initiated empirically due to a previous rash from vancomycin. Operative tissue cultures grew Staphylococcus haemolyticus, Staphylococcus epidermidis and Corynebacterium striatum. Given concern for daptomycin resistance and the reliability of vancomycin susceptibility, daptomycin was discontinued and vancomycin initiated following a graded challenge. Within a few days, the patient developed a diffuse, blanching, erythematous, maculopapular rash and daptomycin was restarted. Over the next 72 h, his rash progressed and he met criteria for drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome. Daptomycin was stopped and oral linezolid initiated; rash improved. C. striatum returned with susceptibility to gentamicin, linezolid, vancomycin and daptomycin. Due to concern for adverse effects on long-term linezolid, daptomycin was restarted and was tolerated for 20 days, at which point purulent drainage from incision increased. The patient underwent another arthroplasty revision and washout. Operative cultures from this surgery were again positive for C. striatum. Repeat C. striatum susceptibilities revealed resistance to daptomycin but retained susceptibility to linezolid. Daptomycin was again changed to linezolid. He completed six weeks of linezolid followed by linezolid 600 mg daily for suppression and ultimately opted for disarticulation. C. striatum has historically been regarded as a contaminant, particularly when grown in tissue culture in the setting of prosthetic joint infection. Based on the available literature and susceptibility patterns, the most appropriate first-line therapy is vancomycin or linezolid.

The purpose of this study was to report the incidence of serotonin syndrome in patients receiving linezolid and SSRIs. This study was a retrospective chart review of inpatients at the Mayo Clinic (Rochester, MN) with concomitant orders or therapy within 14 days for linezolid and an SSRI from 2000 to 2004. The Sternbach criteria and Boyer criteria for diagnosis of serotonin syndrome were used to identify clinical features of serotonin syndrome. Seventy-two patients received linezolid and an SSRI or venlafaxine within 14 days of each other. Fifty-two patients (72%) received concomitant therapy with linezolid and an SSRI or venlafaxine, and 20 patients (28%) did not receive concomitant therapy but received linezolid and an SSRI within a 14-day period. Overall, only 2 patients (3%) had a high probability of serotonin syndrome. In both patients with high probability, symptoms reversed rapidly on discontinuation of serotonergic therapy. The Boyer criteria were much more specific than the Sternbach criteria for identification of serotonin syndrome. On the basis of our experience, we suggest that, if the clinical situation warrants use of linezolid in a patient receiving an SSRI, linezolid may be used concomitantly with SSRIs, without a 14-day washout period and with careful monitoring for signs and symptoms of serotonin syndrome.

Delaying the initiation of antibiotic administration to more than 24 h postinfection resulted in animals with systemic anthrax in various degrees of bacteremia and toxemia. As the onset of symptoms in humans was reported to start on days 1 to 7 postexposure, delaying the initiation of treatment by 24 to 48 h (time frame for mass distribution of antibiotics) may result in sick populations.

He smoked 20 cigarettes a day and drank wine (1 or 2 litres a day). He was affected by hypercholesterolemia and in the past reported relapsed thrombophlebitis in the left leg. Four years before admission to our hospital he underwent large and small left saphenectomy. He had no cardiac events in the past.

At home the symptoms increased and after 8 months the patient was admitted again to the Cardiologic Division of the hospital. At admission he reported dyspnea and chest pain at rest, not only during effort and the ECG showed negative T waves in anterior and inferior leads. Intravenous heparine, nitrates and calcium antagonists stabilized the clinical picture. The following examinations revealed: reduction of the T wave negativity at the ECG registered during chest pain; mild enlargement of the heart at the chest roentgenogram; normal value of the left ventricle and apical and midseptal by ipokinesia at the transthoracic echocardiogram; normal coronary artery at the coronary arteriography. \"Vasospastic angina\" was diagnosed and the patient was discharged after 20 days, asymptomatic.

At physical examination he showed a painful left tibio-tarsal tumefaction, an increased and splitting second heart sound in the pulmonary area and a systolic murmur in the third and fourth left interspace. The ECG showed a severe anterior ischemia, while a new transthoracic echocardiogram revealed a considerable dilatation of the right atrium, right ventricle and the main pulmonary artery with severe tricuspid regurgitation and pulmonary hypertension (mean PAP about 50 mmHg). The following pulmonary perfusion scintigraphy confirmed the diagnosis of pulmonary embolism and the selective right and left pulmonary arteriography exhibited multiple thrombi and large intravascular filling defects. The right heart catheterization confirmed a chronic precapillary pulmonary hypertension (mean PAP = 55 mmHg).

Ultrasound supplemented by Doppler flow detection imaging has become the investigation of choice in the diagnosis of deep vein thrombosis and spiral volumetric computed tomography or ventilation perfusion scan (if the patient is haemodynamically stable) or bedside echocardiography (if the patient is hypotensive) are often the initial investigations in a patient who has a suspected pulmonary thromboembolism. Magnetic resonance venography has only recently been evaluated and may prove in future to be a valuable diagnostic test for both deep vein thrombosis and pulmonary thromboembolism. Treatment requires immediate anticoagulation using either subcutaneous low molecular weight heparin (e.g. enoxaparin 1 mg/kg 12-hourly or dalteparin 100 IU anti Xa/kg twice daily) or intravenous unfractionated heparin (80 U/kg as a bolus then 18 U/kg/hr and adjusted to keep the APTT 1.5-2x the control value). Oral anticoagulation using warfarin is started simultaneously with heparin. Fibrinolytic therapy is considered in all patients with pulmonary thromboembolism in whom there are no contraindications, as the improvement in right ventricular function is greater and the pulmonary artery perfusion defect is less compared with patients treated by anticoagulation alone. Fibrinolytic therapy is usually only considered in patients with deep vein thrombosis if severe limb oedema is present. While streptokinase, urokinase and alteplase have been recommended, alteplase (100 mg over two hours with heparinisation) may be the treatment of choice as alteplase has a shorter half life, has a more rapid effect and may be more effective in lysing older clots, when compared with streptokinase or urokinase. Reteplase (10 U over 2 minutes followed by 10 U 30 minutes later) may be as effective as alteplase. Acute venous thromboembolism is a disorder that carries a high morbidity and mortality. Anticoagulation with or without fibrinolysis is the treatment of choice." }, { "id": "pubmed23n1122_24551", "title": "EkoSonic™ Endovascular System-Directed Thrombolysis in a Patient With COVID-19 Infection Presenting With Bilateral Large Pulmonary Embolism Causing Right Ventricular Strain: A Case Report.", "score": 0.012420757776794928, "content": "We discuss a case of a 31-year-old male patient who presented to the accident and emergency department with shortness of breath and chest pain since the morning of the day of presentation.

He was not vaccinated against the COVID-19 virus. He had not required hospitalization for COVID-19 and his symptoms had improved on day 10 from the date of diagnosis; however, he developed pleuritic chest pain with shortness of breath on the day of presentation. He was found to have tachypnoea, hypoxia, and tachycardia on assessment. His electrocardiogram showed a right bundle branch block with sinus tachycardia. He underwent a CT pulmonary angiography (CTPA) that showed bilateral large pulmonary emboli extending from the main pulmonary arteries bilaterally extending to the sub-segmental level. There was evidence of right heart strain on the scan. He also had a bedside echocardiogram performed after the CT scan, which showed an enlarged right ventricle but no left ventricular thrombus. His blood results showed D-dimer levels of 14,000 ng/mL and troponin T of 255 ng/L. He received treatment with low molecular weight heparin (LMWH) and underwent emergency EkoSonic™ Endovascular System (EKOS) thrombolysis (Boston Scientific, Marlborough, MA). He remained on ultrasound-accelerated thrombolysis (USAT) for the next 12 hours and showed significant improvement and was taken off oxygen post-EKOS thrombolysis.

Cardiac enzyme levels were elevated, and an ECG revealed T-wave inversion in leads III, aVF, V1, and V2 with evolving ST-segment elevation in leads V3 through V5. The findings of a CT scan and MRI of the head were negative; a Doppler ultrasound of the right lower extremity revealed a thrombus extending from the common femoral vein to the popliteal vein. Cardiac catheterization revealed no evidence of epicardial coronary artery disease. CT pulmonary angiography revealed bilateral pulmonary emboli. Transesophageal echocardiography (TEE) showed a 4-cm, dumbbell-shaped mass lodged in a patent foramen ovale, confirming the diagnosis of an impending paradoxical embolism. The patient was started on therapy with unfractionated heparin, and his thrombus resolved spontaneously by hospital day 5. An impending paradoxical embolism is rare but should be suspected in anyone presenting with evidence of both venous and arterial emboli. The therapeutic options include anticoagulation, thrombolysis, and surgical embolectomy. We would propose that initial treatment with anticoagulation therapy and following with serial TEEs may be appropriate therapy in an otherwise stable patient, with surgical embolectomy or thrombolysis reserved for the treatment of thrombi that do not resolve with anticoagulation therapy or for patients with clinical deterioration." }, { "id": "article-17662_23", "title": "Anteroseptal Myocardial Infarction -- Treatment / Management", "score": 0.010206705059646236, "content": "Enoxaparin is given as an initial intravenous dose of 30 mg in all patients followed by 1 mg/kg subcutaneously every 12 hours dosing (can be used as 1 mg/kg SC once daily dose if creatinine clearance is less than 30 mL/min).

Our prospective study focused exclusively on patients affected by pulmonary embolism with a hemodynamic pattern of acute cor pulmonale, investigated at a single center. Particular attention was paid to in-hospital mortality, embolic recurrences, major bleeding and underlying pathologies. This study includes 160 cases (103 women with a median age of 71 years and 57 men with a median age of 65 years) in whom the clinical and echocardiographic findings suggestive of acute pulmonary embolism were confirmed by lung perfusion scan, pulmonary angiography, techniques for the detection of deep vein thrombosis and/or autopsy. The most common clinical manifestations were: dyspnea (92% of cases), tachycardia (80%), syncope (44%), cardiac arrest (22%), and shock (20%). Thoracic pain was present in only 27% of patients. None of the patients showed a normal ECG; a right bundle branch block was found in 47% of cases. T-wave inversion in the precordial leads (32%) was not related to the severity and outcome of pulmonary embolism. Present or previous deep vein thrombosis was found in 53 and 26% of cases, respectively. Only in 2 patients pulmonary embolism was secondary to a deep vein thrombosis of the upper limbs. Intravenous heparin alone was used in 36% of cases, whereas 56% were treated with thrombolytic agents + heparin. Major bleeding occurred in 9% of patients treated with heparin alone, and in 16% of those who received heparin + thrombolytic drugs. Death occurred in 17% of the former, and in 27% of the latter patients. The in-hospital mortality rate was related not only to the presence of cardiac arrest and--to a lower degree--of shock, but also to the recurrence of pulmonary embolism and to the underlying heart disease. No relationship was found between mortality and age, intracardiac thrombi or malignancy. Prognosis was quite different depending on clinical presentation, with a death rate ranging from 11% in the absence of systemic hypertension, and 77% in the presence of cardiac arrest.

He was admitted due to severe dyspnea with oxygen desaturation and heart murmur on the second day after birth. Physical examination showed clear consciousness, cyanosis, dyspnea, RR 70 bpm and a grade II/6 heart murmur. Bp was 56/45 mm Hg (1 mm Hg = 0.133 kPa) and SpO2 around 65%.

ECMO setup: Medtronic pediatric ECMO package (CB2503R1), carmeda membrane oxygenator and centrifugal pump (bio-console 560) were chosen. Direct cannulation of the ascending aorta (Edward FEM008A) and right atrium (TF018090) was performed using techniques that were standard for cardiopulmanory bypass. The ECMO system was primed with 400 ml blood, 5% CaCl(2)1g, 5% sodium bicarbonate 1.5 g, 20% mannitol 2 g, albumin 10 g, and heparin 5 mg. The blood was re-circulated until the temperature was 37 degrees C and blood gases and the electrolytes were in normal range. The patient was weaned from bypass and connected to V-A ECMO. Management of ECMO: the blood flow was set at 150 - 200 ml/kg/min. Venous saturation (SvO2) was maintained at the desired level (75%) by increasing and decreasing extracorporeal blood flow. Systemic blood pressure was maintained at 76/55 - 80/59 mm Hg by adjusting blood volume. Hemoglobin was maintained between 120 - 130 g/L. Platelet count was maintained at &gt; 75,000/mm3 and ACT was maintained at 120 - 190 s. The mechanical ventilation was reduced to lung rest settings (FiO2 35%, RR 10 bpm, PIP 16 cm H(2)O, PEEP 5 cm H2O) to prevent alveolar collapse. Inotropic drug dosages were kept at a low level. The patient was successfully weaned from ECMO following 87 hours treatment. LVEF on day 1, 2 and 3 following ECMO were 20%, 34% and 43% respectively. The circulation was stable after weaning from ECMO with Bp 75/55 mm Hg, HR 160 bpm and LAP 11 mm Hg under inotropic drug suppor with epinephrine [(0.2 microg/(kg.min)], dopamine [(8 microg/(kg.min)], milrinone [(0.56 microg/(kg.min)].

On day 22 off-ECMO, the baby was successfully extubated and weaned from conventional ventilator. On day 58, the patient was discharged. Serial ultrasound imaging studies revealed no cerebral infarction or intracranial hemorrhage during and after ECMO. At the time of hospital discharge, the patient demonstrated clear consciousness with good activity, normal function of heart, lung, liver and kidney. However, more subtle morbidities, such as behavior problems, learning disabilities should be observed ria long term follow-up. The main ECMO complications were pulmonary hemorrhage, bleeding on the sternal wound, tamponade, hemolysis and hyperbilirubinemia.

To help determine the optimal management strategy for normotensive patients with intermediate-risk PE, the Pulmonary Embolism Thrombolysis (PEITHO) study completed enrolment of 1006 patients with evidence of right ventricular dysfunction (by echocardiography or computed tomography) plus a positive troponin test. Patients have been randomised to thrombolytic treatment with tenecteplase versus placebo, and the effects on clinical end points (death or haemodynamic collapse) assessed at 7 and 30 days. The results are expected in spring 2013; long-term follow-up is also being performed. The results of a randomised trial on ultrasound-enhanced low-dose catheter-delivered thrombolysis will also become available soon. While optimisation of treatment with vitamin K antagonists incorporating pharmacogenetic testing is still being pursued, new oral anticoagulants are entering the field of PE treatment and secondary prophylaxis. Following the successful use of rivaroxaban as single oral drug therapy in the EINSTEIN-PE trial, the approval of this drug has recently been extended to cover, apart from deep vein thrombosis, PE as well. The apixaban (AMPLIFY) and edoxaban (HOKUSAI) trials have finished recruitment of PE patients, and their results will become available shortly. In the meantime, the AMPLIFY-EXT trial showed that both the therapeutic (5 mg twice daily) and the prophylactic dose (2.5 mg twice daily) of apixaban are effective and safe for long-term secondary prophylaxis after PE. For the extended prophylaxis (after the reommended initial anticoagulation period) of the (few) patients who are unable to tolerate any form of anticoagulation, low-dose asprin may be a safe albeit moderately efficacious option, as indicated by two recent investigator-initiated trials with a total of 1224 patients." }, { "id": "pubmed23n0853_10392", "title": "An 88-year-old man with syncope and an alternating axis.", "score": 0.009615384615384616, "content": "An 88-year-old man, admitted to the emergency room (ER) after three episodes of syncope within 1 day, reported a precursory of syndrome of light-headedness with rapid palpitations that led to an abrupt loss of consciousness.

In adults, subcutaneous low-molecular-weight heparin (LMWH) is as effective as UFH in the treatment of thrombosis. Because pediatric data are limited, the authors studied the use of enoxaparin in children. Nineteen children (ages 18 days to 19 years; median age, 40 months) with indications for thrombosis treatment or prophylaxis were studied. Six patients (median age, 33 months), treated on a protocol that included pharmacokinetic studies, initially received enoxaparin 1 mg/kg subcutaneously every 12 hours; doses then were adjusted until target plasma levels of 0.5 to 1.2 anti-Xa U/mL were achieved. The records of 13 additional patients treated with enoxaparin off study were reviewed. In the first six patients, enoxaparin pharmacokinetics was found to be similar to that in adults; once targeted levels were achieved, these remained stable. Among all 19 subjects, 14 had treatment of active thrombosis and 5 underwent thrombosis prophylaxis. For treatment of thrombosis, enoxaparin 1 mg/kg initially was administered subcutaneously every 12 hours. Target anti-Xa levels were achieved with 0.55 to 1.5 mg/kg every 12 hours (mean, 0.98 mg/kg; median, 1.0 mg/kg) in 1 to 7 days (median, 1 day). All patients in the treatment group had clinical improvement within 2 to 5 days, and 12 had follow-up radiological studies that confirmed this. For prophylaxis, enoxaparin was given at 1 mg/kg subcutaneously every 24 hours. No new thrombi were clinically evident in this group. There was no major bleeding with enoxaparin; one patient had transient mild mucosal oozing. In this limited population, enoxaparin seems to be a safe, effective, and convenient alternative to UFH in children and adolescents. The adult therapeutic target range of 0.5 to 1.2 anti-Xa U/mL is readily achievable with a starting dose of 1 mg/kg every 12 hours in most children. Initial close monitoring with plasma anti-Xa activity should be done and doses adjusted to achieve target range, particularly in neonates. In the population of this study, enoxaparin seems as effective as UFH in the period immediately thrombotic episode.

The incidence of PE is approximately 60 to 120 per 100 000 people per year. Approximately 60 000 to 100 000 patients die from PE each year in the US. PE should be considered in patients presenting with acute chest pain, shortness of breath, or syncope. The diagnosis is determined by chest imaging. In patients with a systolic blood pressure of at least 90 mm Hg, the following 3 steps can be used to evaluate a patient with possible PE: assessment of the clinical probability of PE, D-dimer testing if indicated, and chest imaging if indicated. The clinical probability of PE can be assessed using a structured score or using clinical gestalt. In patients with a probability of PE that is less than 15%, the presence of 8 clinical characteristics (age &lt;50 years, heart rate &lt;100/min, an oxygen saturation level of &gt; 94%, no recent surgery or trauma, no prior venous thromboembolism event, no hemoptysis, no unilateral leg swelling, and no estrogen use) identifies patients at very low risk of PE in whom no further testing is needed. In patients with low or intermediate clinical probability, a D-dimer level of less than 500 ng/mL is associated with a posttest probability of PE less than 1.85%. In these patients, PE can be excluded without chest imaging. A further refinement of D-dimer threshold is possible in patients aged 50 years and older, and in patients with a low likelihood of PE. Patients with a high probability of PE (ie, &gt;40% probability) should undergo chest imaging, and D-dimer testing is not necessary. In patients with PE and a systolic blood pressure of 90 mm Hg or higher, compared with heparin combined with a vitamin K antagonist such as warfarin followed by warfarin alone, direct oral anticoagulants such as apixaban, edoxaban, rivaroxaban, or dabigatran, are noninferior for treating PE and have a 0.6% lower rate of bleeding. In patients with PE and systolic blood pressure lower than 90 mm Hg, systemic thrombolysis is recommended and is associated with an 1.6% absolute reduction of mortality (from 3.9% to 2.3%). In the US, PE affects approximately 370 000 patients per year and may cause approximately 60 000 to 100 000 deaths per year.

The clinical signs are often non-specific. However, diagnosis and therapy must be done quickly in order to reduce morbidity and mortality. The new (2014) European guidelines for acute pulmonary embolism (PE) focus on risk-adapted diagnostic algorithms and prognosis adapted therapy concepts. According to the hemodynamic presentation the division in a high-risk group (unstable patient with persistent hypotension or shock) or in non-high-risk groups (hemodynamically stable) was proposed. In the high-risk group the immediate diagnosis is usually done by multidetector spiral computed tomography (MDCT) and primarily the medical therapy of right ventricular dysfunction and thrombolysis is recommended.In the non-high-risk group, this is subdivided into an intermediate-risk group and low-risk group, the diagnosis algorithm based on the PE-pretest probability--determined by validated scores. Moreover, the diagnosis is usually secured by MDCT--the new gold standard in the PE-diagnosis, scores, or it can be primarily ruled out due to the high negative predictive value of D-dimer determination. To improve the prognostic risk stratification in non-high-risk group patients the additional detection of right ventricular dysfunction (MDCT, echocardiography), cardiac biomarkers (troponin, NT proBNP) and validated scores (e.g. Pulmonary Embolism Severity Index) is recommended. Therefore, the intermediate-risk group can be further subdivided. For treatment of non-high-risk group patients, the initial anticoagulation (except those with severe renal insufficiency) using low molecular weight heparin/fondaparinux and conversion to vitamin-K antagonists or alternatively with direct oral anticoagulants (DOAK) is recommended. Hemodynamically stable patients with right ventricular dysfunction and myocardial ischemia (Intermediate-high-risk group patients) but with clinically progressive hemodynamic decompensation may benefit from systemic thrombolysis as well. Due to the high risk of bleeding in the PEITHO study, however, a critical individual risk-benefit evaluation should be done. A dose reduced systemic or local ultrasound-assisted thrombolysis could gain importance in the future. For very selected patients in the low-risk group early outpatient treatment could be considered.The diagnosis and treatment of pulmonary embolism remains complex. Improved algorithms support the diagnosis procedures and therapy decisions.

Determination of D-dimers is only meaningful in patients with low or intermediate clinical likelihood. It is safe not to initiate anticoagulation treatment (or to discontinue such treatment) in patients with low clinical likelihood of acute pulmonary embolism and negative D-dimer test (only if methods with 99-100% sensitivity are used). Duplex sonography and pulmonary scintigraphy are only necessary at the centres with a first generation spiral CT and not those with multidetector devices. Investigations in normotensive patients should include echocardiography that should also include assessment of the right ventricular function using echocardiography and determination of biomarkers of pulmonary embolism. Right ventricular dysfunction together with elevated troponins identifies a normotensive group at an increases risk. Highly sensitive troponin T (hsTnT) appears to be particularly valuable. Echocardiography reading might the decisive factor for treatment initiation in patients with massive acute pulmonary embolism. Negative or unclear echocardiography finding warrants spiral CT angiography (CTA). Ventilation/perfusion scan or pulmonary arteriography are recommendable in patients with unclear CTA finding and patients with high clinical likelihood of pulmonary embolism and negative CTA finding. A combination of CTA and CTV also appears useful as it increases the overall sensitivity of the investigation and enables imaging of pelvic veins. Thrombolytic treatment is indicated in haemodynamically unstable patients, patients with a high risk of a massive pulmonary embolism associated with cardiogenic shock or hypotension (systolic pressure below 90 mmHg or a decrease in systolic pressure by &gt; 40 mmHg) or symptoms of acute right-sided heart failure. Thrombolytic treatment is also indicated in pulmonary embolism not receding following heparin treatment, in recurring or expanding pulmonary embolism, in the presence of thrombi in the right heart and in patients with right-to-left shunting through patent foramen ovale. This treatment should also be considered in patients with submassive pulmonary embolism associated with a dysfunction of the right ventricle and increased troponins, and particularly in patients lacking even a relative contraindication of thrombolytic treatment. A thrombolytic of choice is alteplase. Embolectomy or catheterization should be used if thrombolytic treatment is contraindicated or ineffective.

However, since immune-related adverse events (irAEs) are potentially fatal, early recognition and prompt treatment are warranted. One of the rarest but most dramatic irAE is myocarditis, which has significant morbidity and mortality if not recognized and treated early. To report the first case of myocarditis in a patient with metastatic castration-resistant prostate cancer (mCRPC) treated with a combination of nivolumab, an anti-programmed cell death protein 1 antibody, and PROSTVAC, a vector-based therapeutic prostate cancer vaccine. A 79-year-old man with mCRPC metastatic to bone and lymph nodes and a history of atrial fibrillation presented with blurred vision and pain and stiffness in the upper back after 8 weeks on a clinical trial with nivolumab (1 mg/kg) and PROSTVAC, both given every 2 weeks.

Electrocardiogram (ECG) revealed atrial fibrillation with QT prolongation (QTc 514 msec) and left anterior fascicular block, unchanged from baseline. 2D-echocardiogram showed a left ventricular ejection fraction of 65% with an enlarged left atrium, dilated right ventricle, and increased pulmonary artery pressure (45 mmHg). ProBNP was elevated at 1463 pg/mL and peaked at 3066 pg/mL one day after hydration. With a presumed diagnosis of autoimmune myositis and possible myocarditis, the patient was admitted and started on methylprednisolone 1 mg/kg/day. Cardiac MRI showed elevated native myocardial T1 values consistent with myocarditis (Fig. 1). The patient was discharged on a prednisone taper after normalization of cardiac enzymes on day 4. Treatment with PROSTVAC continued for three more months; nivolumab was discontinued. Six months later, patient is doing well, with no residual cardiac damage. Cardiovascular irAEs are relatively rare (&lt; 1%) and have a variety of clinical presentations. Myocarditis is potentially life-threatening and can range from subclinical to fulminant. Therefore, clinical suspicion, early detection, and prompt treatment are imperative (1). The initial diagnostic workup should include cardiac enzymes, ECG, and 2D-echocardiogram. The most commonly observed ECG changes are generalized repolarization abnormalities, prolonged QT interval, and conduction abnormalities (2). An elevated troponin I in the absence of overt coronary artery disease is suggestive of myocarditis and should be evaluated further. Myocardial biopsy is the standard diagnostic procedure; however, a cardiac MRI can achieve a diagnosis when biopsy is not feasible (3). Advancements in parametric mapping techniques have allowed the use of native myocardial T1 in the detection of myocarditis, as it has superior diagnostic performance and higher sensitivity than older parameters (3). Our patient had been treated with an immune checkpoint inhibitor and a therapeutic cancer vaccine to induce effective antitumor activity through immunogenic intensification and presented with muscle stiffness and elevated CK. Although he had no new cardiovascular symptoms, cardiac enzymes were tested to rule out myocardial involvement. MRI with gadolinium confirmed the diagnosis of myocarditis. To date, none of the 1360 patients treated with PROSTVAC as a single agent have developed myocarditis, while myocarditis has been rarely reported in patients treated with nivolumab (&lt; 1%) (1). Whether the combination of PROSTVAC and nivolumab presents an additional risk of myocarditis is unclear. To our knowledge, this is the first case of myocarditis in a patient with mCRPC receiving simultaneous treatment with an immune checkpoint inhibitor and a prostate cancer vaccine. Our experience highlights the importance of suspicion and early intervention in patients who present with cardiac abnormalities after receiving cancer immunotherapy. We propose following protocol: baseline troponin, ECG, and 2D-echocardiogram prior to treatment, then repeated troponin at 2, 4, and 12 weeks post-treatment, then monthly. If troponin becomes positive without alternative explanation, myocarditis should be ruled out with cardiac MRI or myocardial biopsy, and patient should be admitted for treatment with high-dose steroids as early intervention may minimize myocardial injury." }, { "id": "pubmed23n0564_24292", "title": "Is it a pheochromocytoma?", "score": 0.008928571428571428, "content": "The patient is a 44-year-old man with a 4-year history of intermittently elevated blood pressure (BP) controlled by diet and exercise.

Recently, some clinical trials have defended the use of thrombolytics. The objéctive of this paper is to present our experience, although the series is still small. From April 1996 to November 1997, 11 patients were admitted to our Cardiac Intensive Care Unit with the clinical suspicion of PE, 5 of which with great hemodynamic instability and suspicion of massive PE. The clinical presentation was sudden dyspnea and loss of consciousness in 2 patients, dyspnea and hypotension in 2 patients and shock and respiratory arrest in one case. Gasimetry revealed acute hypoxemia and hypocapnia in all cases, average partial blood pressure in O2 (pO2) of 59 mm Hg and CO2 (pCO2) of 19 mm Hg. ECC and thorax x-ray contributed to the diagnosis in 3 patients, transthoracic echocardiography was decisive for the diagnosis in 5 cases, with visualisation of the thrombus by transesophageal echocardiography in 3 patients. All patients were monitored by Swan-Ganz catheter, the average systolic pulmonary artery pressure (PAP) was 74 mm Hg. Thrombolysis with rTPA (10 mg bolus followed by 90 mg in perfusion in 2 hrs) was administered in 6 episodes in 5 patients. Only in the case of the patient in shock were other complications related to the use of thrombolytics namely high digestive hemorrhage. There was a clear clinical improvement in all cases with great relief of dyspnea reduction of cyanosis and jugular engurgitation. The patient in shock recovered systemic pressures and improved the hemodynamic state. A significant reduction in PAP was observed (average of 32.5 mm Hg). PE recurred in two cases: with one death and therapeutic thrombolytic was repeated in the other patient with good results. After discharge, all patients remained asymptomatic under oral anticoagulation.

The patient started passive ROM training the day after the operation while wearing a shoulder abduction orthosis for 3 weeks, followed by immobilization with a sling for 2 weeks. Thereafter, he started active exercise. The axillary nerve palsy was almost completely resolved 3 months after the operation. He achieved a ROM comparable to that of the unaffected side at 1 year after operation. He has had an uneventful post-operative course for 2 years after operation.

Injury corresponded 9 times to stretching mechanism in upper limb traction and came 58 times with osteoarticular lesions (30 anterior dislocations and 28 shoulder fractures). In 11 cases, shoulder active abduction was normal, inspite of deltoïd's complete palsy and this accounted for diagnosis delay. Concerning axillary nerve isolated lesions (35 cases), 7 recovered spontaneously and 28 have been operated. Surgical operation was undertaken 9 months after injury using a combined anterior and posterior approach. Rupture was located in the quadrilateral space and 23 nerve grafts, 4 neurolysis and 1 direct suture were performed. Results were good (muscle measured to M4) and excellent (muscle measured to M5) in 57 per cent of cases. Concerning axillary nerve lesions associated to suprascapular nerve lesions (9 cases) and musculocutaneous nerve (3 cases), all axillary nerve lesions were grafted with 50 per cent of good and very good results. The scapular nerve was neurolysed 6 times with 4 good and excellent results and evaluated irreparable in 3 cases. Musculocutaneous nerve was grafted in all cases with 2 good results out of 3. Posterior cord lesions (8 cases) required an osteotomy of the clavicle. Five grafts and 3 neurolysis were performed with aleatory results. At last, when associated lesions of the rotator cuff muscle were found (12 cases), 6 cases recovered spontaneously and 3 times cuff rupture was small enough to be reinserted with 2 good results. The 6 other cases corresponded to an axillary nerve rupture which were all grafted with 2 good results. On the cuff, result was in relation with lesion's type. Twice a supraspinatus tendon rupture was reinserted with 1 good result and 1 fair result. In 3 older patients, there was a small size rupture which has been reinserted with 1 good result, 1 fair result and 1 failure. At last, one surgical repair of a large rupture couldn't be justified.

The series included 165 men and 68 women, mean age 42 years (range 13-95 years). One hundred fifty-eight practiced sports more or less regularly (73% of the 216 patients) and a sports accident was involved in 121 cases (52.8%). Besides the usual lesions secondary to bone displacement, there were 51 fracture-avulsions of the greater tuberosity, 7 major fractures of the anteroinferior border of the glenoid cavity, 2 fractures of the coracoid process, 10 nerve lesions (6 axillary nerve palsies and 4 partial palsies of the brachial plexus) and 10 rotator cuff tears. Orthopedic reduction was performed in the emergency room in all patients with a dislocated shoulder (82%). Immobilization, elbow to body, was prescribed for 8 to 15 days. Sixteen patients (6.8%) underwent surgery during the days following reduction, 8 for displaced fracture of the greater tuberosity, 7 for important fracture of the glenoid cavity and 1 for avulsion of the rotator cuff. Patient files (n=210) or phone interviews (n=185) were used to assess outcome. Mean follow-up was 38 months (12 - 72 months). All nerve lesions regressed within a few weeks without sequelae. We had 6 cases of retractile capsulitis and 4 cases of reflex dystrophy that regressed totally in 3 to 6 months. Recurrent dislocation was observed in 52 cases (24.7% recurrence rate) with 29 occurring within one year (55.8%). Among the 145 other shoulders, 84 recovered completely (58%), 52 were occasionally bothersome (36%), 8 exhibited repeated subdislocation (5.5%) and one remained pseudoparalytic.

The final proof is taken from polyphasic EMG potentials which are decreased in amplitude and increased in distal latency. Initially the entrapment neuropathy may be treated by immobilization, analgesics, and physiotherapy. A tear of the rotator cuff as well as a frozen shoulder have to be excluded by arthrography. In persistent cases of pain and pathologic EMG findings surgical decompression of the nerve should be done. The trapezius muscle is approached by a postero-superior incision.

Nine patients met the inclusion criteria for the study. All patients were men with ages ranged from 21 to 35 years (average, 27.4 years). The interval between injury and surgery ranged from 4 to 11 months (average, 7.2 months). Atrophy of the supraspinatus, infraspinatus and deltoid muscle and subluxation at the glenohumeral joint was obvious in all patients preoperatively. During the pre-op examination all patients had at least muscle grading 4 on the triceps muscle. The mean post-operative value of shoulder abduction was 112.2° (range: 60-170°) while preoperatively none of the patients was able for abduction (p&lt;0.001). The mean post-operative value of shoulder external rotation was 66° (range: 35-110°) while preoperatively none of them was able for external rotation (p&lt;0.001). Postoperative values of shoulder abduction were significantly better that those of external rotation (p=0.0004). The postoperative average muscle grading for shoulder abduction according the MRC scale was 3.6±0.5 and for the shoulder external rotation was 3.2±0.4. Combined nerve transfer by using the spinal accessory nerve for suprascapular nerve neurotisation and one of the triceps nerve branches for axillary nerve and teres minor branch neurotisation is an excellent choice for shoulder abduction and external rotation restoration." }, { "id": "pubmed23n0299_9923", "title": "[Arthrodesis of the shoulder for post-traumatic palsy of the brachial plexus.

Furthermore, the surgical management of the remaining flail shoulder is still controversial. The post-operative results and the indication for shoulder arthrodesis are evaluated in this study. Between October 1978 and January 1994, 18 gleno-humeral arthrodesis were performed on 18 patients for paralytic shoulder following brachial plexus injury. The average age at the time of operation was 25 years. A C5C6 lesion was present in 2 patients, a C5C6C7 lesion in 8 patients and a C5 to T1 lesion in the remaining 8 patients. Seven patients had a suprascapular nerve reinnervation failure. All these 18 patients recovered an active elbow flexion spontaneously or following direct nerve repair, tendon or free muscle transfer. The average delay between nerve repair and arthrodesis was 2 years and 4 months. For fixation, we always used internal fixation by screws, combined to an external fixator device in 10 cases. 16 patients were reviewed with an average follow-up of 6 years and 10 months (min. 6 months, max. 15 years and 8 months). Two types of complications occurred: 2 cases of gleno-humeral non-union requiring revision with bone-grafting, and 3 humeral fractures in the first 6 months after arthrodesis. The study of the arthrodesis position showed an average abduction of 25 degrees, an average flexion of 18 degrees, an average internal rotation of 22 degrees. The average motion values are 60 degrees of abduction and flexion, 14 degrees of extension, 0 degree of external rotation and 48 degrees of internal rotation. The range of motion depends closely on scapulo-thoracic muscles strength, especially the serratus anterior muscle. A flail hand primarily influences the subjective result. 14 of the 16 patients could easily reach their mouth. The average muscle shoulder strength, evaluated with the Isobex device, is 11 kg for flexion and abduction, 9 kg for adduction, 8 kg for internal rotation and 4 kg for external rotation. Gleno-humeral arthrodesis is a reliable method for restoring shoulder function in case of brachial plexus sequellae lesion, giving more strength, but less external rotation than shoulder nerve repair." }, { "id": "wiki20220301en139_54330", "title": "Shoulder surgery", "score": 0.011600378787878788, "content": "Arthritis or osteolysis of the acromioclavicular joint Arthritis or osteolysis of the acromioclavicular joint can be treated with the Mumford procedure (open or arthroscopic).

We are presented with a patient with risk factors for oropharyngeal cancer, but in whom the examination and tests are normal. What is going on here? This question is reverse psychology: what did the questioner want me to know? This question was asked by an otolaryngologist. He already tells you that the dentist "didn't see anything", so he rules out 1. It is not an abscess of the base of the tongue either, because in three months it would have killed him: neither is 2. So we are left with ankyloglossia, tongue base cancer and non-specific inflammation. When there is doubt that it could be cancer, we should not fool around and order a new CT scan and biopsy. Tongue base cancers are very treacherous and it is one of the fears of any otolaryngologist when he suspects a neoplasm. It is not uncommon for them to arise without exophytic masses or ulcerations of the tongue mucosa and they are difficult to detect on CT when contrast is not used. The correct answer is 4 and I do not think it can be challenged.

A 64-year-old smoker and heavy drinker with no other history of interest. The picture he explains is odynodysphagia of 3 months of evolution and left otalgia. He provides a dentist's report that rules out a dental cause. He also refers to having been visited by different specialists and provides a head and neck CAT scan (without iodine contrast) which is reported as normal. On examination there was a decrease in the propulsive capacity of the tongue; palpation of the base of the left tongue showed an induration of stony consistency of approximately 3cm and with indirect laryngoscopy no ulceration of the mucosa was observed. Cervical palpation is negative for lymphadenopathy. What is your presumptive diagnosis and course of action?

An accidentally displaced lower third molar is a relatively rare complication, but may cause severe tissue injury and medicolegal problems. As few papers and cases have been published on this topic, we report this case to remind dentists on ways to prevent and manage this complication. The patient, a 28-year-old male, had his right lower mandibular third molar extraction in January 2006. The dentist resected the crown and attempted to remove the root but found that it had suddenly disappeared from the socket. Assuming that the root had been suctioned out he closed the wound. The patient was not followed up regularly because he studied abroad. About 3 months later, the patient felt a foreign body sensation over his right throat, and visited a local hospital in Australia. He was told after a computed tomography (CT) scan that there was a root-like radio-opaque image in the pterygomandibular space. The patient came to our hospital for further examination and management in June 2006. We rechecked with both Panorex and CT and confirmed the location of the displaced root. Surgery for retrieving the displaced root was performed under general anesthesia by conventional method without difficulty, and the wound healed uneventfully except for a temporary numbness of the right tongue. This case reminds us that the best way to prevent a displaced mandibular third molar is to evaluate the condition of the tooth carefully preoperatively, select adequate instruments and technique, and take good care during extraction. If an accident does occur, dentists should decide whether to retrieve it immediately by themselves or refer the case to an oral and maxillofacial surgeon, and should not try to remove the displaced root without proper assurance. Localization with images and proper surgical methods are the keys to retrieving the displaced fragment successfully. When immediate retrieval is decided on, Panorex and occlusal view are useful in localizing the displaced fragment. When the fragment moves into a deeper space or the retrieval has been delayed for months, three-dimensional CT seems to be a better choice." }, { "id": "pubmed23n0638_18102", "title": "[Tuberculosis of the tongue initially suspected of tongue cancer: a case report--including the search for recent 16 cases in Japan].", "score": 0.009615384615384616, "content": "A 56-year-old man, having no particular past history, was admitted to our hospital, with a 9-month history of painful ulcerated lesion of the tongue and a 6-month history of productive cough.

In this regard, we here report an original case of idiopathic granuloma of the tongue not secondary to Melkerson Rosenthal syndrome and being part of benign tumors of the oral cavity. The study involved a 60-year old female patient, with no particular past medical history, presenting with discomfort during mastication secondary to a swelling on the free edge of the tongue which had occurred one month before her admission. Physical examination showed overgrowth at the level of the right edge of the tongue measuring 15 mm along its longer axis. The tongue was not plicated and there was no cervical adenopathy. The remainder of the physical examination was normal. MRI of the oral cavity showed suspected necrotizing tissue lesion on the right free edge of the mobile tongue measuring 15x12x19 mm without signs of extension to the ipsilateral lingual pedicle or to the floor of the oral cavity and without cervical adenomegalies. Biopsy of tongue lesion showed gigantocellular epithelioid granulomas without caseous necrosis or histological signs of malignancy.

On physical examination, a cutaneous nodule was noted on the umbilical region and the patient was referred to the dermatology clinic. The patient was reexamined and an erythematous nodule was observed in the umbilicus measuring 2.5 cm in diameter. The patient denied pain, change in bowel habits, or weight loss. There were no other abdominal masses, no sign of ascites, and no regional lymphadenopathy. A skin biopsy from the nodule showed mucinous adenocarcinoma. Immunohistochemical staining was positive for carcinoembryonic antigen, and negative for cytokeratin (CK)7 and CK20. These results were consistent with a Sister Mary Joseph's nodule and led to the diagnosis of an occult colon carcinoma. The patient had no risk factors for colorectal carcinoma. The patient underwent surgery in another hospital, and died 3 months after the initial diagnosis of Sister Mary Joseph's nodule.

Surgical intraoperative neck positioning and airway management are hypothesized as causative factors. The condition presents with ipsilateral motor paralysis of the tongue and vocal cords. Postoperatively, patients often present with dysphonia, dysphagia, and difficulty swallowing. We discuss a unique case of Tapia's syndrome occurring after retrosigmoid craniotomy for left vestibular schwannoma resection in a 42-year-old male. General anesthesia was uneventful with an atraumatic, grade 2a intubation and a normal endotracheal tube cuff pressure of 30 cm of water. The patient was positioned laterally, even though the exact head position was not documented. Institutional practice in these cases is for the head to be maintained neutral or with a slight turn. An uneventful subtotal resection of the tumor was performed after retrosigmoid exposure. Postoperatively, the patient complained of left-sided mouth tingling, a hoarse voice, and tongue weakness which impacted his ability to chew and swallow. He had mild left-sided facial weakness and decreased sensation in the V1 and V2 distribution of the trigeminal nerve. Postoperative brain MRI showed postsurgical changes without evidence of neurological or vascular involvement. Fiberoptic endoscopy performed in the otolaryngology clinic showed immobility of the right vocal cord. Consequently, Tapia's syndrome was diagnosed. He later underwent a right vocal fold injection with Prolaryn gel (Merz North America, Inc, Greensboro, NC, USA) via flexible laryngoscopy with a slight improvement in his dysphonia. At his last visit, he declined further interventions based on acceptable voice quality. Tapia's syndrome can occur due to the close anatomical proximity of the hypoglossal and recurrent laryngeal nerves as they pass lateral to the oropharynx and hypopharynx. This predisposes the nerves to anesthetic and surgical insults such as over-stretching of the nerves during head manipulation and trauma to the nerve fibers following laryngoscopy. Our case report highlights this potential rare complication to anesthetic and surgical teams. Awareness of this concurrent paralysis can assist practitioners to rapidly diagnose and treat patients who present in this way postoperatively. It can also enable avoidance of causative factors and remind practitioners of the importance of meticulous perioperative documentation." }, { "id": "pubmed23n0043_12589", "title": "[Ultrasound staging research of progressive pathology of the base of the tongue].", "score": 0.009174311926605505, "content": "Diagnosis of tongue tumours is often retarded mainly because tumours grow prevalently in deep muscular layers.

These considerations led us to evaluate ultrasonography (US) as a diagnostic tool for neoplastic lesions of this region. Initially 10 normal patients were studied in order to become familiar with US anatomy of the area. In a second phase our study involved 24 patients with diagnosed carcinoma of the tongue base and 26 patients with clinical suspect of neoplasm in the region. US examination was carried out with real-time equipment provided by a 5 Mhz convex transducer. Patients were examined in supine position with the neck hyperextended. Longitudinal, oblique and transverse scan of the submental region were obtained. The study showed that US gives detailed images of the floor of the mouth and the tongue. Neoplastic infiltration of the base of the tongue is clearly recognizable as a hypoechoic area. It was possible to detect masses ranging from 1.4 to 3.8 cm. In cases of larger lesions, US was useful in evaluating deep infiltration, whereas in other cases the method allowed the diagnosis of small lesions with submucosal growth.

A previously healthy 24-year-old African American man presented with a 2-week history of fever, chills, dyspnea, abdominal pain and vomiting, nonbloody diarrhea, anorexia, and body aches. He occasionally smoked marijuana but had no pets, and denied sick contact or recent travel. Physical examination was remarkable for tachypnea, tachycardia, pyrexia, icteric sclera, dry oral mucosa, moderate-to-severe gingival inflammation, and dental caries involving the upper and lower molars. The oropharynx was clear. He had tenderness over the sternocleidomastoid muscles bilaterally, and nontender cervical lymphadenopathy. Chest examination revealed reduced breath sounds in both bases with fine crackles at the right base. Examination of the cardiovascular and gastrointestinal systems was significant for tenderness in the right upper quadrant with no rebound. Laboratory findings were significant for leukocytosis with a left shift, anemia, abnormal liver function tests, elevated creatine phosphokinase, and positive blood culture for F. necrophorum. Chest radiographs and computed tomography scans revealed multilobar cavitary nodular densities with pleural effusions. Duplex sonography of the neck demonstrated thrombosed left internal jugular vein with complete occlusion of the lumen, thrombosed left subclavian, and axillary veins with minimal blood flow. There was also a small thrombus in both the right internal jugular and right subclavian veins with partial occlusion of their lumina. He was prescribed penicillin, metronidazole, and anticoagulation therapy and had complete resolution of the lung lesions and marginal improvement of the bilateral neck thrombophlebitis. He was awaiting dental procedures. A case is reported of extensive bilateral septic thrombophlebitis of the deep neck veins secondary to periodontal disease. To the best of my knowledge, this is the first case of bilateral Lemierre syndrome due to periodontal disease reported in the literature. It highlights the typical septic thrombophlebitis of Lemierre syndrome and its protean manifestations, such as hepatitis and rhabdomyolysis.

In this site cancer usually presents at an early stage with sudden hoarseness. Hoarseness of more than three weeks' duration requires laryngoscopic examination. Particularly the cancers of the floor of the mouth and the borders on the tongue can be detected early because of the accessibility of these sites, which allows proper inspection and palpation. The most common clinical manifestation of oral cancer is an indurated ulcer. An oral ulcer present for more than three weeks is an indication for biopsy.

Therefore, the complete removal of thromboemboli in all calf arteries is difficult even if completion angiography or radiological intervention is performed. The purpose of this study is to identify whether limb salvage could be achieved if at least one ankle artery was revascularized by surgical thromboembolectomy. We also observed the effectiveness of below-knee popliteal approach. Over 1 year, surgical thromboembolectomy via below-knee popliteal artery was performed on 18 acutely ischemic limbs in 14 consecutive patients. All patients were diagnosed based on clinical symptoms and computed tomography (CT) angiography. Surgical thromboembolectomy was terminated when a pulse was detected by a handheld vascular Doppler device in at least one ankle artery after closing the arteriotomy. Patients were observed during postoperative anticoagulation therapy. Of the 14 patients, 1 died and 1 underwent amputation due to the already necrotized lesion in the foot. After 1 week of anticoagulation therapy, two or more arterial pulses were detected at the ankles in all 15 limbs from the remaining 12 patients. During the 6 to 18 months of follow-up, all 15 limbs were salvaged successfully. In acute limb ischemia, successful limb salvage could be achieved by the revascularization of at least one ankle artery by surgical thromboembolectomy with concomitant anticoagulation therapy. Below-knee popliteal approach is an effective method and is worth for further study compared with other approaches.

Successful outcomes of surgical treatment for acute arterial occlusion after TKA have been frequently reported in the literature; however, few reports have described conservative treatment. This case report describes the successful conservative treatment of popliteal artery occlusion after TKA. CASE REPORT We report 2 cases of popliteal artery occlusion after TKA that were managed with conservative treatment. In Case 1, a 68-year-old woman presented with a weak dorsalis pedis pulse in the foot and weakness to dorsiflexion of the toe on the operative side immediately after TKA. The operative lower extremity arterial ultrasonography and computed tomography angiography demonstrated the popliteal artery occlusion. In Case 2, a 79-year-old woman presented a cold right foot and lack of popliteal and dorsalis pedis pulse in the operated extremity immediately after TKA, and Doppler ultrasound did not reveal a flow for the dorsalis pedis artery. In both patients, urgent angiographies showed popliteal artery occlusion, and blood flow was observable in the anterior tibial, peroneal, and foot arteries collateral perfusion. Thus, conservative treatments were chosen, and anticoagulant and vasodilator therapies were undergone in both patients. At 6 months after surgery, they were able to walk without intermittent claudication. CONCLUSIONS Conservative treatment can be a good option for popliteal artery occlusion after TKA in cases of rich collateral circulation." }, { "id": "pubmed23n0491_20682", "title": "Hyperbaric oxygenation combined with streptokinase for treatment of arterial thromboembolism of the lower leg.", "score": 0.016085271317829455, "content": "Thromboembolic occlusion of peripheral arteries is a common problem in patients referred to vascular surgery departments. Standard treatments include catheter aspiration techniques, use of fibrinolytic agents and surgical thrombendarterectomy. Recent reports have described the use of hyperbaric oxygen therapy in patients with limb ischemia, yet their main focus has been on patients with chronic disorders. We present the case of a 74-year-old woman with atrial fibrillation and acute thromboembolic occlusion of the posterior tibial artery. The patient presented with severe pain in the right calf, unresponsive to non-opioid parenteral analgesia and accompanied by coldness, numbness and partial motor palsy of the right foot. After 60 minutes of oxygenation in a hyperbaric chamber with a pressure of 2.2 bar, the pain receded, although without signs of restored blood flow in the occluded artery. After fibrinolytic therapy with streptokinase, patency of the posterior tibial artery was verified by return of palpable pulsations and color Doppler ultrasonography. By combining hyperbaric oxygenation and streptokinase in the treatment of lower-leg arterial thromboembolism we achieved regression of ischemic pain, prolongation of the survival time of tissues compromised by ischemia and resolved the cause of the ischemia. We believe the use of this therapeutic strategy in selected cases of peripheral arterial thromboembolism is justified." }, { "id": "pubmed23n1063_9587", "title": "Acute Limb Ischemia: A Rare Complication of COVID-19.", "score": 0.014543605390287312, "content": "A 60-year-old male with a history of primary hypertension presented to the emergency department of a tertiary care hospital, in Pakistan, with complaints of fever, cough, and shortness of breath.

Laboratory investigation revealed elevated D-dimer, international normalized ratio, and total leukocyte count. C-reactive protein was markedly elevated (82.5 mg/L), indicating the state of a cytokine release syndrome (CRS). Treatment started with antibiotics, prophylactic enoxaparin (40-mg subcutaneous once daily), methyl prednisone 60 mg BD and multivitamins. Intravenous tocilizumab (TCZ) 6 mg/kg was started from Day 1 to address the CRS. On Day 3, he complained of pain in the right lower limb with signs of hypothermia, numbness, and slight blackening of the right foot. Peripheral pulses were not palpable, and vascular ultrasound showed no vascular flow in the popliteal, anterior and posterior tibial, and dorsalis pedis artery. The Vascular Surgery department declared the limb unsalvageable and right limb above-knee amputation. On Day 9, the right foot was blackened and atrophied extending up to the knee. Above-knee amputation was done, and he was discharged on rivaroxaban after 48 hours of observation. We conclude that heparin is effective in treating coronavirus disease 2019-associated coagulopathy, while TCZ, simultaneously, decreases the severity of CRS.

Massive ileo-femoral DVT is usually the cause and prompt treatment is mandatory as it represents a medical emergency. Reported amputation rates range from 12% to 25% and mortality ranges from 25% to 40%. Limb ischemia results from obstruction to arterial inflow secondary to extreme levels of venous hypertension. Primary treatment goal is restoration of venous outflow and can be achieved by endovascular or surgical techniques. After thrombus removal an underlying iliac vein stenosis may be present. May-Thurner syndrome, a condition where the left common iliac vein is compressed by the right iliac artery, is the most prevelant iliac stenotic lesion. We report a case of a 57 years-old male, smoker, with no significant medical history, who presented to the emergency department with excruciating sudden left limb pain and swelling, with no trauma history, with a 2-hour onset. On physical examination he showed significant edema, purplish discoloration of the entire leg and absent dorsalis pedis artery pulse.

Endovascular approaches such as catheter-directed thrombolysis (CDT) or pharmacomecanical thrombolysis (PMT) are becoming the treatment of choice to achieve venous outflow in DVT. In cases of PCD, when rapid restauration of venous outflow is mandatory, CDT has the disadvantage of having a long mean treatment time. This way, surgical thrombectomy still plays an important role in cases of PCD, especially if PMT is not available.

Inadequate and late treatment of the lower limbs embolism is associated with high morbidity and mortality rate. The aim of this paper was to study the aetiology of lower limbs embolism and to detect factors influencing early and late results after the operative treatment. The study included 204 patients with 224 lower limbs embolism, treated surgically at the Institute of Cardiovascular Diseases of the Clinical Centre of Serbia in Belgrade in the period between 1993 and 1997. There were 107 (52.2%) female and 97 (47.8%) male patients. Thirty two (14.3%) patients were younger than 50 years, 64 (28.6%) were between 51 and 65, 101 (45.1%) between 66-75, while 27 patients (12.1%), were older than 75. Twenty (8.9%) patients were admitted less than 6 hours before the operation, 79 (33.3%) between 6 and 24 hours, and 125 (55.8%) more than 24 hours before the operation (Table 1). One hundred (53.6%) patients had motor and 133 (59.4%) sensor paralysis on admission. Table 2 shows arterial localization of the lower limbs embolism. The popliteal artery was involved in most cases. During the operation transfemoral arterial approach was used in 132 (58.9%) cases, while transpopliteal in 92 (41.1%) cases. Fourteen cases required bypass surgery, 43 fasciotomy, 2 intraoperative streptokinase and 4 intraoperative angiography. All patients were controlled using physical and CW Doppler ultrasonographic examinations immediately after the operation, and then one, six and 12 months, as well as every year.

When ischemia is recognized as contributing to pedal ulceration and infection in the diabetic foot, quantitation of its severity may be difficult. Standard clinical evaluation of trophic changes is limited in an infected foot with its accompanying swelling, edema, and erythema. A palpable pedal pulse does not preclude the possibility of the presence of limb-threatening ischemia. Additional non-invasive vascular studies should be undertaken for these patients. Management of the diabetic foot is often a complex clinical problem. However, the principles of care are simple, including correction of systemic factors, such as blood glucose control, cardiovascular risk factor management, and smoking, as well as local factor correction, such as debridement, pressure relief, infection control, and revascularization when indicated. When a patient presents with evidence of infection, adequate drainage and antibiotic therapy are mandatory. The next step should be performed to differentiate the more common neuropathic ulcerations from the truly ischemic ulceration. Symptoms of rest pain or claudication are not often helpful because many of these patients are asymptomatic as a result of the presence of their neuropathy and inactivity. If an infected foot requires debridement or open partial forefoot amputation, observing the wound on a daily base is also important. Once infection is eradicated, there should be prompt signs of healing, including the development of wound granulation within several days. If wounds are not showing signs of prompt healing, arteriography is necessary. Early aggressive drainage, debridement, and local foot amputations combined with liberal use of revascularization results in cumulative limb salvage of 74% at 5 years in high-risk groups. Others report that pedal bypass to the ischemic infected foot is effective and safe as long as infection adequately controlled. These studies strongly suggest that early recognition and aggressive surgical drainage of pedal sepsis followed by surgical revascularization is critical to achieving maximal limb salvage in the high-risk population. Patients who have diabetes present a unique challenge in lower extremity revascularization because of the distal origination of many bypasses, distal distribution of the occlusive disease, and the frequently calcified arterial wall. An aggressive multidisciplinary approach to foot disease associated with diabetes involving the primary care provider, medical specialists, interventional radiology, and podiatric, plastic, and vascular surgeons will provide optimal medical and surgical care.

The severity of the chronic occlusive process leads to characteristic symptoms in the extremity: claudication, rest pain, skin ulcerations and gangrene. Chronic progressive lesions permit enlargement of collateral blood supply which, for a time, minimizes the severity of symptoms. Milde degrees of arterial insufficiency (claudication) can be treated conservatively. Unreconstructed chronic critical ischemia predicts a poor outcome in terms of survival and limb salvage. The outlook with arterial reconstructive surgery is by far better. Arteriography ist the most reliable diagnostic test for occlusive lesions. It ist essential for the operative planning. Vein-bypass procedures are, if feasible, very effective in most cases.

After selective pedicle screws instrumentation and corrective maneuvers motor evoked potentials (MEP) began to decrease with no concomitant changes in somato-sensory evoked potentials recordings.The instrumentation was released first partially than completely with rod removal but the patient demonstrated constantly increasing serious neurological motor deficit of the whole right lower limb. Every technical cause of the MEP changes was eliminated and during the wake-up test the right foot was found to be pale and cold with no popliteal and dorsalis pedis pulses palpable. The patient was repositioned and the pelvic pad was placed more cranially. Instantly, the pulse and color returned to the patient's foot. Following MEP recordings showed gradual return of motor function up to the baseline at the end of the surgery, whereas somato-sensory evoked potentials were within normal range through the whole procedure.This case emphasizes the importance of the proper pelvic pad positioning during the complex spine surgeries performed in prone position of the patient. A few cases of neurological complications have been described which were the result of vascular occlusion after prolonged pressure in the inguinal area during posterior scoliosis surgery when the patient was in prone position.

The author and others [14,15], including those who have promulgated the use of thrombolytic therapy, have come to reasonable conclusions regarding how to deal with ALI: The diagnosis of ALI should be established rapidly. Determine its classification based on the patient's history and physical examination, and promptly institute anticoagulant therapy. Determine whether or not the patient should be taken emergently for surgical thromboembolectomy or a revascularization procedure versus arteriogram and possible thrombolysis. Adjunctive therapy such as antiplatelet agents (e.g., GIIb/IIIa antagonists) and other anticoagulant agents must be better investigated before recommendations can be made. Save life over limb.

The symptoms and findings of acute arterial occlusion are characterized by \"the six Ps\": pain of sudden onset in the hypoperfused extremity, paleness, pulselessness, paresthesias, paralysis and, in the extreme case, prostration with the symptoms of shock. With embolization in arterial segments with only minimal residual perfusion via collaterals (for example, the femoral bifurcation), a complete ischemic syndrome is usually incurred manifesting the six Ps as delineated. If preformed collateral systems provide some perfusion distal to an arterial occlusion (for example, in the common iliac artery), there is frequently an incomplete ischemic syndrome observed which is characterized by pain, paleness and pulselessness. Peripheral arterial embolism has a predilection for the femoral bifurcation, the superficial femoral artery and the popliteal artery. In principle, however, embolization can occur in every arterial segment. The diagnosis of the acute ischemic syndrome can generally be established on the basis of the history and physical examination. Diagnostic aid can be provided by electronic segmental oscillography to demonstrate diminished or absent oscillations and with the Doppler sonographically-determined systolic arterial pressure at the ankle which, in the case of severe ischemia, is less than 50 mmHg. Arteriography provides the most accurate morphological information. Abrupt occlusion of the vessel and no collateral perfusion especially in the absence of arteriosclerotic changes are strongly indicative of embolism but not conclusive.

The decision about the treatment of acute CLI is related to the clinical and functional condition of the patient. Anamnesis must inquire about recent ischemic or hemorrhagic events in the cardiovascular, gastro-intestinal and urinary apparatuses, or the presence of disorders of coagulation and fibrinolysis. An objective clinical examination and a multidimensional assessment must evaluate the degree of functional impairment and provide the basis of a therapeutic strategy (cost/benefit ratio). Diagnostic examination in the frail elderly patient (FP) involves only the ultrasonographic method, to localize the level of thromboembolic occlusion, which is followed by angiography in the non-frail patient (NFP). In the case of proximal occlusion (of the iliac or femoro-popliteal arteries), the elective treatment in both groups of patients is thromboendarterectomy, plus transcutaneous angioplastics or by-pass in NFP, followed by prostacyclin or heparin infusions. Distal occlusion (below the popliteal artery) in FP is treated only with prostacyclin or heparin, whereas in NFP, fibrinolysis is the elective treatment, followed by prostacyclin or heparin. In the cases of distal gangrene, before amputation is performed, a \"limb salvage\" operation must be considered. After the acute phase of medical or surgical treatment, vasoactive or antiplatelet drugs are employed in FP, whereas in NFP the use of coumadin is the preferred treatment to counteract the rethrombosis and prevent new embolizations.

Another boy was examined under anesthesia and the operation was canceled because the testis could be brought into the scrotum. Subsequently, on followup evaluation 2 to 8 years later the ipsilateral testis could not be manipulated into the scrotum. Of the boys 6 then were treated with a short course of human chorionic gonadotropin. Four patients had a positive response but in 3 the testis was undescended again at examination 6 months later. Of the boys 6 ultimately underwent orchiopexy.

Does treatment make a difference?", "score": 0.01489136195018548, "content": "The testis which remains nonscrotal beyond puberty will not produce sperm. While much of the data presented imply that therapy of cryptorchidism during childhood will decrease the likelihood of infertility, the available data do not substantiate this. There are also inadequate data to indicate whether treatment at very young ages in childhood decreases the risk of infertility. In fact, it is not clear that fertility rates among males who were unilaterally cryptorchid is different than that of the unaffected male population! Therefore, verification is needed to determine whether or not fertility is decreased in cryptorchidism. Paternity is a better index for verification than sperm counts since it is known that men with subnormal sperm counts may have normal paternity rates. Such verification using paternity may require more than fathering a child, such as the age of the father at the birth of the first child, length of marriage or partnership before birth of the first or subsequent children, or duration of intercourse without contraception to birth. Because of the multiple etiologies of the cryptorchid state, factors such as the relative size of the testis before treatment, and the position of the testis and the histology of the testis need to be considered since the small testis, the abdominal testis and the testis with the most histologic changes would appear to be at the greatest risk for defects in spermatogenesis. Until these data become available, most physicians are likely to recommend treatment of the undescended testis when detected if the child is older than six months. However, it must be remembered that there are no data to indicate benefit of early treatment. Before treatment is initiated, the physician must be careful to rule out a retractile testis. Also, the possibility of ascent of the testis which may occur during midchildhood, the age of physiologically normal hypogonadotropism, must be remembered. The testis which was previously normally descended but resides much of the time during midchildhood years within the inguinal canal may be a variant of normal and not require therapy. The approach to the patient with cryptorchidism must involve a careful history and repeated examinations looking for a cause and for accurate position of the testis. If the testis can be moved from the nonscrotal position into the scrotum, the potential function of the testis should not be harmed.(ABSTRACT TRUNCATED AT 400 WORDS)" }, { "id": "pubmed23n0318_8095", "title": "Effect of a combined GnRH/hCG therapy in boys with undescended testicles: evaluated in relation to testicular localization within the first week after birth.", "score": 0.01473922902494331, "content": "Among 509 boys referred with undescended testicles, 112 had true undescended testicles unilaterally and 62 bilaterally.

The MeSH headings used in our MEDLINE search included <iundescended testicle, retractile testicle, ectopic testicle, ascended testicle, referral and consultation,</i and <iorchiopexy</i. An <iundescended testis</i is defined as the true absence of one testis (or both testes) from normal scrotal position. Ectopic and ascended testes will likewise be absent from the scrotum, the latter having been present at one point in development. Differentiating among testicular examination findings is important, as descended and retractile testes are managed conservatively, while prompt surgical intervention should be offered for ascended, ectopic, and undescended testes. Uncertainty surrounding the diagnosis of an undescended testis causes anxiety, might lead to unwarranted imaging, and might increase the wait list for specialty assessment. For this reason, avoidance of ultrasound in the evaluation of undescended testes was included in the recent Choosing Wisely Canada campaign. We seek to clarify the physical examination findings in the evaluation of possible undescended testes, the suggested referral parameters, and the subsequent management. Undescended testes and their variants are common. As decision for referral is based on the primary care physician's physical examination findings, we clarify distinguishing between normal and abnormal findings on testicular examination to aid in appropriate referral for subspecialist evaluation. Consultation, if needed, should be sought at 6 months' corrected gestational age, or at detection if later than 6 months, without delay for ultrasound imaging, as surgical management is recommended for those patients with undescended, ectopic, or ascended testes." }, { "id": "pubmed23n0613_13618", "title": "Further evidence for acquired undescended testicle in the UK and its incompatibility with current recommendations in the Hall Report.", "score": 0.013515870247645622, "content": "The 4th edition of the Hall Report [Hall DMB.

The natural history of acquired undescended testis means that recommendations as set out in the Hall Report \"that no further check after six weeks need be made if the testes are 'well down' at that stage\" cannot be successful, and all concerned in childhood surveillance will need to be aware of this and remain vigilant at least until puberty.

The following information was obtained from the hospital medical records: indication for operation, date of the operation, laterality (unilateral or bilateral), the surgical findings and whether previous testicular position played a role in the decision to perform orchidopexy. For each boy who underwent orchidopexy for undescended testis, previous testicular positions up until the date of the operation were obtained from the appropriate youth health care institutions.

Its main function is to prevent the posterior dislocation of the tibia in relation to the femur, providing 95% of the strength to resist the tibial posterior displacement. Along with the anterior cruciate ligament (ACL) the PCL controls the passive 'screw home' mechanism of the knee in terminal knee extension. It also provides mechanical support for the collateral ligaments during valgus or varus stress of the knee. PCL ruptures are uncommon apparently due to its strong fibre structure. The most frequent injury mechanism in isolated PCL tears is a direct blow on the anterior tibia with the knee flexed thus driving the tibia posteriorly. Automobile accidents (in which the knee hits the dashboard) and soccer injuries (in which an athlete receives a blow to the anterior surface of the tibia during knee flexion) characteristically produce this type of injury. In other PCL injury mechanisms (hyperextension, hyperflexion or rotational injuries with associated valgum/varum stress), other knee structures are also often damaged. The most characteristic diagnostic finding in a knee with a PCL rupture is the 'posterior sag sign' meaning the apparent disappearance of the tibial tubercle in lateral inspection when the knee is flexed 90 degrees. This is due to gravity-assisted posterior displacement of the tibia in relation to the femur. A positive posterior drawer test performed at 90 degrees of flexion and a knee hyperextension sign are sensitive but nonspecific tests. False negative findings are frequent, especially in acute cases. If necessary, the clinical diagnosis of the PCL tear can be verified by magnetic resonance imaging, examination under anaesthesia, arthroscopy, or a combination of these modalities. If a PCL avulsion fragment has been dislocated, surgical treatment is recommended. In isolated, complete midsubstance tears of the PCL the majority of the recent studies recommend conservative treatment, since abnormal residual posterior laxity1 in most of these knees is consistent with functional stability and minimal symptoms. This has been the case even in athletes. In isolated PCL tears, the outcome seems to depend more on the muscular (quadriceps) status of the knee than on the amount of residual posterior laxity. Therefore, the conservative treatment protocol emphasises intensive quadriceps exercises, and only a short (under 2 weeks) immobilisation period followed by early controlled activities and early weightbearing.(ABSTRACT TRUNCATED AT 400 WORDS)" }, { "id": "pubmed23n0540_6354", "title": "Surgical treatment of multiple knee ligament injuries in 44 patients: 2-8 years follow-up results.", "score": 0.015753259295026557, "content": "The purpose of the study was to evaluate the mid-term results of surgical treatment in different groups of patients with multiple knee ligament injuries. Review of our patients' records revealed that 48 acute and chronic patients were surgically treated for combined knee injury. Due to severe capsular damage in these injuries, open techniques were used. In our treatment protocol, avulsed ligaments and tears of the posterolateral and posteromedial corner were repaired if possible, whereas midsubstance tears of cruciate ligaments and chronic cases were reconstructed with autografts. Postoperatively, an accelerated program of rehabilitation was introduced, aiming to progressively mobilize the joint and improve muscle endurance. For the follow-up evaluation we designed a protocol composed of two parts. In the first part, anatomical lesions were recorded and in the second part, clinical evaluation was performed using the Lysholm score, the Tegner rating system, the IKDC evaluation form, and the KT1000. Student's t tests and chi-square tests were used for data analysis. Forty-eight patients (mean age 28.6+/-11.9 years; 41 males) were classified according to the specific anatomical structures involved. Group A included 12 anterior cruciate ligament (ACL) and medial structure injuries, group B included 11 ACL or posterior cruciate ligament (PCL) ruptures combined with posterolateral injuries, and group C consisted of 25 knee dislocations (ACL and PCL ruptures which might be combined with damage of the collateral ligaments). Thirty-eight patients were surgically treated during the acute phase and ten patients were treated chronically. Forty-four patients (91.6%) were followed up at a mean of 51.3+/-29.9 months. Average Lysholm score was 87+/-12.3; average Tegner score was 5.09+/-2.19 before accident and 4.34+/-2.12 in re-examination; IKDC score was A in 10 cases, B in 22, C in 6, and D in 6.

Posterior cruciate ligament tears should only be treated by a few centers, since they demand a high degree of experience.

The affected knee flexed approximately 60 degrees and the ipsilateral hip flexed, abducted and externally rotated so that the plane of the knee motion runs parallel to the floor. The examiner instructs the patient to raise the affected leg off the examining table and to extend the affected knee gradually. If the lower leg is internally rotated suddenly, with the knee subluxated at an angle of approximately 20 degrees , followed by the reduction in flexion, this test is regarded as positive. This test was investigated on 51 anterior cruciate ligament (ACL) deficient knees, being positive in 30 knees (Group P) and negative in 21 (Group N) with the positive rate of 59%. There was no significant correlation between the result of this test and the clinical features, but Group N included relatively small number of females and recurrent injuries tended to occur more frequently in Group P. Thirty-six knees received ACL reconstruction subsequently. There was no statistically significant difference between the groups in the side-to-side difference in anterior knee laxity at one year postoperatively. However, three patients with the side-to side difference of more than 3 mm belonged to Group P.

The authors analyzed two consecutive series of 60 and 50 patients operated by the same surgeon for a chronic rupture of the anterior cruciate ligament, one by reconstruction of the cruciate ligament with a free graft of the patellar tendon supplemented by an external extra-articular plasty made with a quadriceps tendon graft and the second with an isolated free patellar tendon graft. Anterior laxity was measured before and after surgery, by dynamic X-rays and by the Medmetric KT-1000 arthrometer. Functional results were evaluated four years after operation, with the French A.R.P.E.GE score based on sport activity level and intensity. Anterior laxity was not different before operation in both groups and there was no difference between males and females. Medmetric KT-1000 arthrometer showed the same negative differential laxity immediately after surgery in both groups and the same evolution during the first 4 years, without any significant difference on laxity on the middle aspect of the knee. Radiological results were different. After a 4 years follow-up, anterior laxity did not show significant difference on the medial compartment of the knee (5.3 +/- 2.3 mm and 5.5 +/- 1.7 mm), but there was a significant minor laxity in the lateral compartment for the lateral extra-articular plasty group (11.0 +/- 2.3 mm against 14.8 +/- 3.8 mm)(p = 0.002). Functional results and sport activity were similar in both groups. Examination showed 4 positive pivot shift tests (2 \"sliding\" and 2 positive) in the group with extra-articular plasty, even though 8 positive pivot shift tests in the isolated ACL group (5 \"sliding\" and 3 positive) were found. This study, as well as five others studies found in literature, was not randomized. In all these series, the surgical techniques, the rehabilitation programs and the functional score evaluation were too different to allow any pertinent comparison. Extra-articular plasty helps to control the laxity of the lateral compartment of the knee which is incompletely controlled by ACL reconstruction, particularly in chronic cases. This is proved by radiological measurements and pivot shift tests. Jensen in 1983, about 205 patients with a 4 year follow-up and Noyes, which used an allograft patellar tendon, found an advantage to do extra-articular plasty. But Strum (in 1989), as O'Brien (in 1991) and Roth (in 1987), did not found any advantage with extra-articular plasty. It is therefore obvious, after a four-year follow-up, that extra-articular supplementation presents an advantage for reconstruction of the ACL. by a free graft of the patellar tendon in chronic cases.

Between 1990 and 1997, 41 patients aged 44.5 +/- 4.5 years (28 men, 25 right side) underwent intra-articular reconstruction of the ACL. Clinical and radiological assessment using the IKDC criteria was obtained at a mean 62 months postoperatively using manual instrumental measurements with KT-1000. The indication for reconstruction was instability in daily life activities for 40 patients and difficulties encountered in sports activities in one; there were three cases of remodeling. Arthroscopy was used in all cases to perform a patellar tendon graft (bone-tendon-bone in 30 cases associated with extra-articular lateral reinforcement in eleven). There were no significant complications. Among 12 patients who initially participated in competition sports, seven were able to resume their activity at their former level. At last follow-up, global IKDC score was A for 12, B for 25, and C for three and D for one. All patients scored C or D had a poor IKDC symptom score, basically because of pain. Motion was not modified. The IKDC radiology score was A for 25, B for 15 and C for one, but the three cases of remodeling did not progress. Prognostic factors for overall IKDC result were: age of the patient at the time of reconstruction (under 45 years), and the delay to surgery for accident victims (less than one year). The following criteria had no effect at last follow-up: gender, sport practiced, type of initial laxity (anterior alone or global anterior), presence of meniscal damage, preservation of the medial and/or lateral meniscus, chondral injury observed peroperatively, and use of a lateral reinforcement. Radiographic remodeling observed in this group of 41 patients was related to delay from accident to surgery (p=0.0007) and preservation of the medial meniscus (p=0.03). Age, gender, type of activity before surgery, degree of initial and residual laxity had no statistically significant effect on remodeling. Age over 40 years is not a contraindication for arthroscopic free patellar tendon graft for the treatment of chronic anterior laxity. Using rigorous preoperative assessment criteria (delay from accident to surgery, absence of joint space narrowing on the AP and lateral view before intervention, symptomatic instability in daily life activities and motivated patient) this type of procedure can be performed safely and provides good functional outcome at five years.

All patients underwent an acute knee arthroscopy with subsequent ACL reconstruction according to the type of lesion. The results were evaluated according to the clinical examination, Lysholm and Tegner activity scores. We compared 2 surgical techniques (Internal Brace, All-Inside ACL reconstruction) and assessed the possible occurrence of complications. RESULTS The injury was most often observed in patients aged 20-40 years, when mainly sports activities put a major strain on the knee joint. After performing ACL reconstruction, all patients reported a subjective improvement in the overall condition. The number of complications was very low - only in connection with a slower warm-up of the knee joint after surgery. DISCUSSION All patients achieved full stabilization of the knee joint, which is objectified by an increase in the Lysholm score. The improvement in patient's subjective feelings is also confirmed by the increase in Tegner activity scores. Only a few patients experienced a slight restriction of movement in the 8th week after surgery, but thanks to intensive rehabilitation the function of the knee joint was completely restored within 3 months of the operation. CONCLUSIONS Our study proves that if the set rules are followed, it is possible to perform the ACL reconstruction already in the acute phase. However, in order to choose this approach, the patient's motivation, gently performed procedure and early intensive rehabilitation are necessary. When meeting these criteria, the patient is able to return to normal life, including sports activities, quite early and there is no increased risk of complications.

The ramp lesion is a special type of medial meniscal tear with high prevalence associated with anterior cruciate ligament rupture; the prevalence increases with time from anterior cruciate ligament injury. Age and gender are risk factors affecting the prevalence of the ramp lesion. Cross-sectional study; Level of evidence, 3. From April 2002 to October 2007, 868 consecutive knees were diagnosed as having an anterior cruciate ligament injury and received arthroscopic surgery for anterior cruciate ligament reconstruction. All the patients had verified tears of the ramp area under arthroscopy. The prevalence of the ramp lesion was evaluated retrospectively. Then, all cases were divided into different groups depending on the time interval from anterior cruciate ligament injury to anterior cruciate ligament reconstruction and other relevant risk factors such as age and gender. The effects of age, gender, and time from injury on the prevalence of ramp lesions were analyzed. Among 868 knees that underwent surgery for anterior cruciate ligament reconstruction, 144 knees were diagnosed as having a ramp lesion. The mean age was 24.7 years; there were 113 male and 31 female patients. The mean time from injury to anterior cruciate ligament reconstruction was 27.2 months. The prevalence of ramp lesions was 16.6%, which was analyzed as a logarithmic correlation with time from injury. Patients younger than 30 years of age and male patients had a significantly higher prevalence of ramp lesions. The ramp lesion is a common meniscal injury that can occur at the time of anterior cruciate ligament rupture or as a result of knee laxity associated with anterior cruciate ligament insufficiency. The prevalence of ramp lesion in this patient group was 16.6%, which increased with time until 24 months after initial injury.

Although originally believed to represent atypical variants of leiomyoma or leiomyosarcoma, recent studies have demonstrated that only a subset of such tumors actually display well developed immunohistochemical, ultrastructural features of smooth muscle differentiation. Most gastrointestinal mesenchymal tumors are of uncertain histogenesis. Current studies have shown a striking morphological and immunophenotypic similarities of these tumors with the interstitial cells of Cajal. And that they may originate from stem cells that differentiate toward a pacemaker cell phenotype. Most GIST's have a co-expression of Kit (CD117) or CD34, which is also express in interstitial cells of Cajal. This review will attempt to summarize the current knowledge and understanding of these lesions based on review of the literature, with an analysis of the criteria for distinguishing between benign and malignant tumors. We report a Gastrointestinal Stromal Tumor of the stomach with prominent cystic degeneration. The patient had diarrhea, abdominal pain and was found to have abdominal mass. X-ray and computed axial tomography examination showed a lesion that seems to be a pancreatic cystic lesion. At laparotomy a large intramural tumor located in the stomach was found. Histologically, the lesion was composed of epithelioid and spindle cells embedded in an abundant myxoid stroma. Tumor cells showed positive staining for vimentin and CD34 positive.

GIMTs were rediagnosed by using standard immunostaining technique in paraffin-embedded tissue. The expression level of CD117, CD34, Desmin, SMA and PS100 were detected by immunohistochemical method. Among 210 cases of GIMTs, 127 cases were Gastrointestinal stromal tumors (GISTs) (60.5%), 33 leiomyomas and leiomyosarcomas (15.7%), 27 neurogenic tumours (12.8%), and 23 miscellaneous tumors (11.0%). The incidences of GIST, leiomyoma and leiomyosarcoma were similar among men and women. Men were more likely to develop neurogenic tumors and miscellaneous tumors than women.

Calcification is not a usual clinicopathological feature of GISTs [1-3], and although a number of rectal GISTs have been reported [4-9], we have found no cases so far of rectal GIST presenting as a submucosal calculus. In general, GISTs are rare mesenchymal tumors of the gastrointestinal tract (nerve tissue, smooth muscle). Histology and immunohistochemistry discriminate gastrointestinal stromal tumors from leiomyomas and neurinomas. The most important location is the stomach; the rectal location is rare. Usually, the classic signs of malignancy such as cellular invasion and metastasis are missing. A set of histologic criteria stratifies GIST for risk of malignant behavior such as mitotic activity and tumor size, cellular pleomorphism, developmental stage of the cell and quantity of cytoplasma [7,13]. Tumors with a high mitotic activity and size above 5 cm are considered malignant. Recent pharmacological advances such as tyrosine kinase inhibitors have determined c-kit (i.e., CD117) as the most important marker, amongst others.

The main manifestations of gastric stromal tumors are upper gastrointestinal hemorrhage 61.3% (19/31), 7 patients with acute hemorrhage and 12 with chronic hemorrhage. Most of them were malignant. Abdominal malaises and/or distention 32.3% (10/31) and abdominal pain 22.6% (7/31). Gastroscopy, ultrasound gastroscopy, computed tomography, B type ultrasound and upper gastrointestinal X-ray series are helpful to diagnosis. But the final diagnosis is decided by pathological and immunohistochemistry examinations. Gastric stromal tumors exhibit consistent immunohistochemical expressions of CD(117) and/or CD(34). The operative treatment is thought of the first choice. Effect of the chemotherapy isn't satisfied. There is no standard chemotherapy for gastric stromal tumors. Gastric stromal tumor is a kind of separated submucosal tumor which is different from leiomyoma, leiomyosarcoma and neurogenic tumors. Pathological and immunohistochemistry inspectations are very important to make clear diagnosis.

However, there is limited evidence to suggest that the gastrointestinal stromal tumors (GIST) in Carney triad lack CD117 (c-kit) mutations (i.e., they are wild-type), and hence these GISTs may prove unresponsive to Imatinib.

Although GISTs typically express CD117 (KIT), often express CD34, and sometimes express alpha-smooth muscle actin (SMA), the relative frequency of these markers has not been characterized in large series of GISTs of different sites, and the CD117 expression has not been fully characterized in intra-abdominal tumors. In this study, we immunohistochemically analyzed 292 GISTs throughout the GI tract, including omentum and mesentery, and compared the immunoreactivities with 211 other tumors that may enter in the differential diagnosis. GISTs were defined in this study as CD117-positive primary spindied or epithelioid mesenchymal tumors of the GI tract, omentum, or mesentery. The CD34 positivity of GISTs varied from 47% in small bowel to 96 to 100% in rectum and esophagus, whereas SMA expression showed the opposite patterns and was most frequent in the GISTs of small bowel (47%) and rarest in the GISTs of rectum and esophagus (10-13%). Desmin was seen only occasionally. S100 positivity was rare but was seen most frequently in small intestinal GISTs (15%). True leiomyomas from esophagus, muscularis mucosae of colorectum, and pericolic leiomyomas similar to uterine leiomyomas were negative for CD117 and CD34 and positive for SMA and desmin (46 of 46). Inflammatory fibroid polyps of stomach and small intestine were negative for CD117 but were often positive for CD34 (6 of 8) and variable for SMA (3 of 8). Inflammatory myofibroblastic tumors involving gastric or colonic wall were negative for CD117 but some showed CD117-positive endothelia. GI schwannomas were all negative for CD117 and positive for S100 protein (11 of 11).

Among other CD117-positive tumors were intestinal metastatic melanomas (8 of 11) and extraskeletal Ewing's sarcomas (5 of 11), two of which were abdominal. In conclusion, strong CD117 expression defines most primary GI mesenchymal tumors as GISTs, which show different patterns for CD34 and SMA in various parts of the GI tract.

Because GISTs, like the interstitial cells of Cajal, the gastrointestinal pacemaker cells, express CD117 (c-kit protein), the origin of GISTs from the interstitial cells of Cajal has been recently proposed. Comparison of GISTs primary in the omentum and mesentery to GISTs primary in the tubular gastrointestinal tract is of particular diagnostic and histogenetic interest in view of the possible similarity of these tumors with the GIST group. In this study, we analyzed 14 omental and 12 mesenteric primary mesenchymal tumors representing smooth muscle tumors or GISTs. These tumors were phenotypically compared with gastric and small intestinal GISTs, leiomyomas of the esophagus, and leiomyosarcomas of the retroperitoneum. Most (13 of 14) omental and mesenteric (10 of 12) tumors showed histologic features similar to GISTs with elongated spindle cells or epithelioid cells with high cellularity; most of these tumors showed low mitotic activity. Omental and mesenteric GISTs were typically positive for CD117 and less consistently for CD34. They often showed alpha-smooth muscle actin reactivity but were virtually negative for desmin and S-100 protein. One omental and two mesenteric tumors showed features of leiomyosarcoma with ovoid, less elongated nuclei, cytoplasmic eosinophilia; all these tumors had significant mitotic activity. These tumors were positive for alpha-smooth muscle actin and two of them for desmin, but all were negative for CD34 and CD117, similar to retroperitoneal leiomyosarcomas. Tumor-related mortality occurred in the group of mesenteric GISTs, but not in the group of omental GISTs. In contrast, all three patients with a true leiomyosarcoma of the omentum or mesentery had documented liver metastases or died of tumor. In summary, we show that tumors phenotypically identical with GISTs occur as primary tumors in the omentum and mesentery. The occurrence of CD117-positive tumors outside the gastrointestinal tract militates against an origin of these tumors exclusively from the interstitial cells of Cajal." }, { "id": "pubmed23n0712_11040", "title": "Hemoperitoneum caused by a ruptured GIST located in the posterior gastric wall managed by endoscopic diagnosis and laparoscopic treatment: case report and literature review.", "score": 0.012811359669998414, "content": "A case of hemoperitoneum caused by a ruptured gastrointestinal stromal tumor (GIST) of the posterior gastric wall is presented.

Its main function is to prevent the posterior dislocation of the tibia in relation to the femur, providing 95% of the strength to resist the tibial posterior displacement. Along with the anterior cruciate ligament (ACL) the PCL controls the passive 'screw home' mechanism of the knee in terminal knee extension. It also provides mechanical support for the collateral ligaments during valgus or varus stress of the knee. PCL ruptures are uncommon apparently due to its strong fibre structure. The most frequent injury mechanism in isolated PCL tears is a direct blow on the anterior tibia with the knee flexed thus driving the tibia posteriorly. Automobile accidents (in which the knee hits the dashboard) and soccer injuries (in which an athlete receives a blow to the anterior surface of the tibia during knee flexion) characteristically produce this type of injury. In other PCL injury mechanisms (hyperextension, hyperflexion or rotational injuries with associated valgum/varum stress), other knee structures are also often damaged. The most characteristic diagnostic finding in a knee with a PCL rupture is the 'posterior sag sign' meaning the apparent disappearance of the tibial tubercle in lateral inspection when the knee is flexed 90 degrees. This is due to gravity-assisted posterior displacement of the tibia in relation to the femur. A positive posterior drawer test performed at 90 degrees of flexion and a knee hyperextension sign are sensitive but nonspecific tests. False negative findings are frequent, especially in acute cases. If necessary, the clinical diagnosis of the PCL tear can be verified by magnetic resonance imaging, examination under anaesthesia, arthroscopy, or a combination of these modalities. If a PCL avulsion fragment has been dislocated, surgical treatment is recommended. In isolated, complete midsubstance tears of the PCL the majority of the recent studies recommend conservative treatment, since abnormal residual posterior laxity1 in most of these knees is consistent with functional stability and minimal symptoms. This has been the case even in athletes. In isolated PCL tears, the outcome seems to depend more on the muscular (quadriceps) status of the knee than on the amount of residual posterior laxity.

Review of our patients' records revealed that 48 acute and chronic patients were surgically treated for combined knee injury. Due to severe capsular damage in these injuries, open techniques were used. In our treatment protocol, avulsed ligaments and tears of the posterolateral and posteromedial corner were repaired if possible, whereas midsubstance tears of cruciate ligaments and chronic cases were reconstructed with autografts. Postoperatively, an accelerated program of rehabilitation was introduced, aiming to progressively mobilize the joint and improve muscle endurance. For the follow-up evaluation we designed a protocol composed of two parts. In the first part, anatomical lesions were recorded and in the second part, clinical evaluation was performed using the Lysholm score, the Tegner rating system, the IKDC evaluation form, and the KT1000. Student's t tests and chi-square tests were used for data analysis. Forty-eight patients (mean age 28.6+/-11.9 years; 41 males) were classified according to the specific anatomical structures involved. Group A included 12 anterior cruciate ligament (ACL) and medial structure injuries, group B included 11 ACL or posterior cruciate ligament (PCL) ruptures combined with posterolateral injuries, and group C consisted of 25 knee dislocations (ACL and PCL ruptures which might be combined with damage of the collateral ligaments). Thirty-eight patients were surgically treated during the acute phase and ten patients were treated chronically. Forty-four patients (91.6%) were followed up at a mean of 51.3+/-29.9 months. Average Lysholm score was 87+/-12.3; average Tegner score was 5.09+/-2.19 before accident and 4.34+/-2.12 in re-examination; IKDC score was A in 10 cases, B in 22, C in 6, and D in 6.

When a doctor suspects ACL injury in a person who reports a popping sound in the knee followed by swelling, pain, and instability of the knee joint, they can perform several tests to evaluate the damage to the knee. These tests include the pivot-shift test, anterior drawer test, and Lachman test. The pivot-shift test involves flexing the knee while holding onto the ankle and slightly rotating the tibia inwards. In the anterior drawer test, the examiner flexes the knees to 90 degrees, sits on the person's feet, and gently pulls the tibia towards him or herself. The Lachman test is performed by placing one hand on the person's thigh and the other on the tibia and pulling the tibia forward.

We included studies that used arthroscopy as the gold standard for measuring the accuracy of the physical examination and magnetic resonance imaging (MRI) for meniscal and ligamentous knee damage. We included all studies on the use of radiographs in pseudogout. We extracted all data in duplicate and abstracted physical examination and MRI results into 2 x 2 tables. Among the 5 decision rules for deciding when to use plain films in knee fractures, the Ottawa knee rules (injury due to trauma and age &gt;55 years, tenderness at the head of the fibula or the patella, inability to bear weight for 4 steps, or inability to flex the knee to 90 degrees) have the strongest supporting evidence.

Eighteen knees of 18 athletes (14 men and 4 women) with an average age of 21.6 years (range 16-32 years) were assessed with a Cybex 6000 model isokinetic apparatus. The average internal between occurrence of the injury and assessment was 10.2 months (range 2-48 months). There was an associated meniscal injury in eight of the knees. Athletes with any other kind of associated injury, limitation, or blockage of the movement of the joint, significant pain during the exam, or interval between injury and exam of less than two months were excluded from the study. The parameters studied were the peak torque-velocity and flexor-extensor relationships at the constant angular velocities of 60 degrees/sec and 240 degrees/sec. Previous warming-up was done by means of an ergometric bicycle and adaptation with 3 submaximal repetitions. The contra-lateral side, which presented no injury, was used as control. Peak torque (PT) at the constant velocity of 60 degrees/sec was greater than that at 240 degrees/sec for knees with and without injuries. However, there was no significant difference between the injured and uninjured sides at 60 degrees/sec or at 240 degrees/sec.

It also restrains excessive forward movement in the leg and limits rotational movements in the knee. Injury An anterior cruciate ligament injury results from excess tension on the ligament. This can come from a sudden stop or twisting motion of the knee. A few initial symptoms include swelling, knee instability, and pain. A popping sound or sensation may or may not be heard when the ACL first tears. A following symptom usually includes the feeling of the knee \"giving out\".

The authors analyzed two consecutive series of 60 and 50 patients operated by the same surgeon for a chronic rupture of the anterior cruciate ligament, one by reconstruction of the cruciate ligament with a free graft of the patellar tendon supplemented by an external extra-articular plasty made with a quadriceps tendon graft and the second with an isolated free patellar tendon graft. Anterior laxity was measured before and after surgery, by dynamic X-rays and by the Medmetric KT-1000 arthrometer. Functional results were evaluated four years after operation, with the French A.R.P.E.GE score based on sport activity level and intensity. Anterior laxity was not different before operation in both groups and there was no difference between males and females. Medmetric KT-1000 arthrometer showed the same negative differential laxity immediately after surgery in both groups and the same evolution during the first 4 years, without any significant difference on laxity on the middle aspect of the knee. Radiological results were different. After a 4 years follow-up, anterior laxity did not show significant difference on the medial compartment of the knee (5.3 +/- 2.3 mm and 5.5 +/- 1.7 mm), but there was a significant minor laxity in the lateral compartment for the lateral extra-articular plasty group (11.0 +/- 2.3 mm against 14.8 +/- 3.8 mm)(p = 0.002). Functional results and sport activity were similar in both groups. Examination showed 4 positive pivot shift tests (2 \"sliding\" and 2 positive) in the group with extra-articular plasty, even though 8 positive pivot shift tests in the isolated ACL group (5 \"sliding\" and 3 positive) were found. This study, as well as five others studies found in literature, was not randomized. In all these series, the surgical techniques, the rehabilitation programs and the functional score evaluation were too different to allow any pertinent comparison. Extra-articular plasty helps to control the laxity of the lateral compartment of the knee which is incompletely controlled by ACL reconstruction, particularly in chronic cases. This is proved by radiological measurements and pivot shift tests. Jensen in 1983, about 205 patients with a 4 year follow-up and Noyes, which used an allograft patellar tendon, found an advantage to do extra-articular plasty. But Strum (in 1989), as O'Brien (in 1991) and Roth (in 1987), did not found any advantage with extra-articular plasty. It is therefore obvious, after a four-year follow-up, that extra-articular supplementation presents an advantage for reconstruction of the ACL. by a free graft of the patellar tendon in chronic cases.

It is striking in this question that we are told that our patient has returned to Spain, but not from where (which could help us to make digressions about the possible cause). However, the description of the picture is very exhaustive as well as typical, so the question is easy. It is a disease that produces fever, arthralgias and a generalized exanthema with petechiae on the lower limbs. The CBC shows leukopenia accompanied by plateletopenia and elevated transaminases. Malaria has been ruled out as a possible cause. All the data are highly suggestive of Dengue, especially the plateletopenia and petechiae (suggestive of capillary fragility), answer 3 correct.
It is striking in this question that we are told that our patient has returned to Spain, but not from where (which could help us to make digressions about the possible cause). However, the description of the picture is very exhaustive as well as typical, so the question is easy. It is a disease that produces fever, arthralgias and a generalized exanthema with petechiae on the lower limbs. The CBC shows leukopenia accompanied by plateletopenia and elevated transaminases. Malaria has been ruled out as a possible cause. All the data are highly suggestive of Dengue, especially the plateletopenia and petechiae (suggestive of capillary fragility), [HIDDEN].
A 54-year-old man diagnosed with type 2 diabetes mellitus comes to our office. He reported a fever of 40ºC with chills and shivering, arthromyalgia and headache, for which he started treatment with paracetamol. The symptoms started 24 hours before his return to Spain. Three days later she presented a generalized maculopapular rash that evolved into more intense petechiae on the lower limbs. She presented blood tests with leukopenia with 3,200/mm3 and platelets 91,000/mm3 and severe elevation of aminotransferases. The thick blood drop, peripheral blood smear, PCR and malaria antigen are negative. What is the most likely diagnosis?

Vector-borne diseases are an important part of infectious diseases. Dengue fever is one of the travel-related infections that has been reported increasingly in recent years through the development of diagnostic methods. The aim of this report was to present two Dengue fever cases originating from travel. There was a story of mosquito bite during a trip to Sri Lanka travel in our first case. The patient was 30 years old and maculopapular rash appeared on the fifth day of contact. Three days after the onset of the rash, she has admitted to our clinic, complaining with fever and chills. Increased leukopenia and muscle enzymes were detected in the laboratory analysis. Real-time reverse transcriptase polimerase chain reaction (RT-PCR) was positive in the serum sample. The patient was followed up with supportive care and discharged by improvement. The second case, a 24-year-old male, had a story of mosquito bite during his trip to Malaysia. After the patient complained of fever, chills, fever, nausea, vomiting and muscle pain, the Dengue virus (DENV) NS1 antigen test performed in this country was found to be positive. In the second case, there was no maculopapular rash and laboratory analysis showed an increase in leukopenia, thrombocytopenia and muscle enzymes. RT-PCR positivity was detected in the serum sample. The patient was followed up with supportive treatment and discharged with cure. DENV infections are caused by DENV which is common in the tropical areas of the world. There are four DENV-1, DENV-2, DENV-3 and DENV-4 serotypes. DENV infections can present different clinical manifestations such as asymptomatic disease, viral syndrome, Dengue haemorrhagic fever, and Dengue shock syndrome. Dengue fever is often accompanied by arthritis, maculopapular rash and high fever. Our cases were defined as Dengue fever according to this definition. In the diagnosis of the disease, it is necessary first to be suspicious of the disease and the travel history must be questioned. In the definitive diagnosis, virus isolation, antigen, nucleic acid detection and serological tests are used. The virus can be isolated from blood, serum, urine and tissues. In the first five days after beginning of the symptoms associated with DENV infections, serum RT-PCR and Dengue NS1 antigen test may be positive." }, { "id": "pubmed23n1111_11167", "title": "COVID-19 Pneumonia and Dengue Fever Coinfection in an Individual From Southeast Asia.", "score": 0.01873249299719888, "content": "COVID-19 infection is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which was declared a pandemic in 2020.

COVID-19 pneumonia and dengue fever coinfection is a relatively difficult diagnosis to be established considering the similarities in the clinical manifestation of both diseases. I hereby report an unusual case of dual diagnosis involving COVID-19 pneumonia and dengue fever (DF) on the same day of presentation to the hospital. A 62-year-old male presented to the emergency department with a fever of six days duration associated with chills, rigors, arthralgia, myalgia, and a generalized pinpoint rash over the chest and abdomen. He had contact with a worker who recently tested positive for COVID-19. However, his vital signs were stable with peripheral capillary oxygen saturation (SPO2) of 99% under room air. Laboratory investigations showed polycythemia, increased hematocrit levels, and thrombocytopenia. Liver function tests showed evidence of acute hepatitis. Otherwise, the basic metabolic panel and coagulation profile were normal. Viral screens for hepatitis B, hepatitis C, and human immunodeficiency virus (HIV) were negative. The posterior-anterior chest radiograph of the patient showed ground glass opacity in both middle and lower zones of the lungs, which is mostly peripheral with preservation of lung markings. The diagnosis was confirmed by a positive SARS-CoV-2 polymerase chain reaction (PCR) test with a cycle threshold (CT) value of 19.97 and positive immunoglobulin M (IgM) and immunoglobulin G (IgG) titers on the dengue serology panel on the same day of testing. Predisposing risk factors were chronic medical illnesses (type 2 diabetes mellitus, hypertension, and ischemic heart disease) and exposure to probable COVID-19-infected individuals.

Apropos of 2 cases].", "score": 0.01803107139982291, "content": "BACKGROUND. Dengue is an acute febrile illness caused by several arthropod-born viruses and characterized by biphasic fever, myalgia or arthralgia, rash, leukopenia and lymphadenopathy. Its diagnosis is based on knowledge of the geographic distribution of dengue viruses. CASE REPORTS Case no 1: A 11 year-old boy suffered from sudden onset of fever accompanied by retro-orbital headache, arthralgia and diffuse myalgia. There was no rash. Hemogram showed: hemoglobin: 11.6 g%; leukocytes: 3,400/mm3 (PMN: 76%); platelets: 190,000/mm3. A diagnosis of viral infection was considered, but, as the boy had recently been to the French West-Indies, a serologic study was performed. This was negative 2 days after the onset of disease and positive (specific IgM for the 4 dengue types), 13 days later. Case no 2: A 7 year-old boy suffered from sudden onset of fever. Severe calf muscle pain 4 days later led to his admission. Creatine phosphokinase activity was very high: 83,100 units (N: 30-120). Hemogram showed: hemoglobin: 11.4 g%; leukocytes: 2,500/mm3 (PMN: 60%); platelets: 124,000/mm3. A diagnosis of acute myositis was considered, but as the patient had recently visited Venezuela, a serologic study was performed. This was negative 8 days after the onset of disease and positive (specific IgM for the 4 dengue types) 16 days later. CONCLUSION. The first case is characteristic of the classical form of dengue fever. The second patient presented with very localized myalgia. The diagnosis in both cases was facilitated by the knowledge that the patient had recently stayed in an endemic area." }, { "id": "pubmed23n0904_2108", "title": "First case of imported chikungunya infection in Croatia, 2016.", "score": 0.017042606516290727, "content": "In recent years, several European countries reported cases of imported chikungunya infection. We present the first imported clinically manifested chikungunya fever in Croatia. A 27-year-old woman returned to Croatia on 21 March 2016, after she stayed in Costa Rica for two months where she had noticed a mosquito bite on her left forearm. Five days after the mosquito bite she developed severe arthralgias, fever and erythematous papular rash. In next few days symptoms gradually subsided. After ten days she felt better, but arthralgias re-appeared accompanied with morning stiffness. Two weeks after the onset of the disease she visited the infectious diseases outpatient department. The physical examination revealed rash on the trunk, extremities, palms and soles. Laboratory findings showed slightly elevated liver transaminases. Serological tests performed on day 20 after disease onset showed a high titer of chikungunya virus (CHIKV) IgM and IgG antibodies which indicated CHIKV infection. CHIKV-RNA was not detected. Serology to dengue and Zika virus was negative. The patient was treated with nonsteroid anti-inflammatory drugs and paracetamol. Her symptoms ameliorated, however, three months later she still complaint of arthralgias.

The first imported Zika virus disease in China was admitted to Ganxian People's Hospital in Jiangxi Province on February 6th, 2016, and the patient received isolation treatment for 9 days and cured later. The effect of antiviral treatments including Xiyanping injection was evaluated based on clinical diagnosis and treatment process of the patient. A 34-year old male patient was admitted with chief complaint of fever for 9 days, orbital pain and itching rash for 4 days on February 6th, 2016. (1) Epidemiological characteristics: the patient was bitted by mosquitoes during his business trip in Venezuela since January 1st, where Zika virus disease was spreading. On January 20th he had dizziness without fever, and the symptom disappeared after taking medicines without details. Paroxysmal dizziness, chills and mild fever without myalgia was experienced on January 28th. On February 3rd small red rash appeared in the neck, spreading to anterior part of chest, limbs and trunk, and the fever, fatigue, nausea was continued, and a new symptom of paroxysmal pain in back of ears and orbits appeared, during which he had not go to hospital. The symptoms relieved on February 4th. He returned to Ganxian County on February 5th, he had yellow stool 3 times with normal temperature, without abdominal pain, and red rash still appeared in the neck. He went to Ganxian People's Hospital on February 6th, 2016. (2) Clinical manifestation: the vital signs showed a temperature of 36.8?centigrade, a pulse rate of 80 bpm, a respiratory rate of 20 bpm, and a blood pressure of 110/70 mmHg (1 mmHg = 0.133 kPa). It was showed by physical examination that red rash appeared in the neck, and no superficial enlarged lymph nodes were found. Bilateral conjunctival congestion was obvious, physiological reflex existed and pathological reflex was not found. (3) Auxiliary lab test and examination: no abnormal finding were revealed throughout examination and laboratory tests, including routine blood test, liver function, renal function, serum myocardial enzyme, electrolyte, blood sugar, C-reactive protein (CRP), troponin I (TnI), and procalcitonin (PCT), except slight prolongation in activated partial thromboplastin time (APTT, 38.6 s) on February 6th; and slightly dense shadow in left lung in lung CT scan, considering inflammatory changes and slight emphysema (especially in the left lower lung) as well as bilateral renal calculus on February 8th. No significant abnormalities were found in electrocardiogram and B ultrasound test of liver, spleen, and pancreas. (4) Virus confirmation: Zika virus nucleic acid was positive reported by Jiangxi Province Center for Disease Control and Prevention (CDC) on February 7th and Chinese CDC on February 9th, respectively, though Dengue virus were negative reported by Ganzhou CDC on February 6th. Right after the first diagnosis, anyone who had been in close contact with the patient received medical monitoring. (5)Treatment process: on February 6th, symptomatic treatment was prescribed since admitted into the infectious isolation wards and daily intravenous drip of Xiyanping injection 250 mg was prescribed for antiviral therapy. On February 7th, the patient had no fever, with occasional chills, neck rash was disappeared, orbital pain relieved and bilateral conjunctival hyperemia range was paler and narrowed, and his condition improved. Ibuprofen was administered for defervesce 3 times a day when his temperature reached to 37.5?centigrade at 16:00. On February 8th, the patient had no fever, times of chills was significantly reduced, without myalgia and rash, orbital pain and conjunctival hyperemia further recovered. On February 9th, bilateral eyes slightly tingling, mild conjunctival congestion, no fever chills or other discomfort was found. The chloramphenicol eye drops was prescribed for relieving sting pain with conjunctival congestion twice a day as recombinant human interferon alpha eye drops was out of store. The patient was comfortable from February 11th to February 13th. Blood and urine test for Zika were reported negative by the Chinese CDC and Jiangxi Province CDC. Because all the discharge criteria were satisfied, the patient was discharged on February 14th. At present, there is no specific effective drug to prevent and treat Zika virus disease effectually. After receiving symptomatic treatment and antiviral treatments including Xiyanping injection, the patient's symptoms were relieved. Zika virus nucleic acid in blood and urine was negative. The patient was discharged. Combination of traditional Chinese medicine and Western medicine maybe a good method to prevent and treat Zika virus disease." }, { "id": "pubmed23n0593_2461", "title": "[Chikungunya: fever and joint pains after vacation in a tropical area].", "score": 0.015109323432343235, "content": "A 27-year-old man was admitted to our hospital, two days after returning from a vacation in Mauritius, with fever, chills, headache and myalgia, as well as arthritis of the legs.

The risk of developing a severe fatal disease in humans, the possibility of being infected with aerosols and the risk of being used as a biological weapon make the disease still an important health problem all over the world as there is no a specific treatment and vaccine that has proven effective againt the virus today. The pathogenesis of the disease is not known, but vascular endothelial damage is prominent. Therefore, it progresses with thrombocytopenia, anemia, leukopenia and this hematological findings can be confused with hematological malignancies. Acute lymphoblastic leukemia (ALL) is a malignancy included in differential diagnoses and occurs as a result of mutations occuring at a stage of differentiation in the lymphoid precursor cells in the bone marrow. In this study, we present a case of ALL who was diagnosed with CCHF simultaneously. A 43-year old female patient who works in the library and does not have a chronic disease other than asthma and thyroid disorder, has admitted to our hospital with the complaints of intermittent fever, weakness, generalized joint and body pain for about 3 weeks.

Brucella Rose Bengal and Coombs tube agglutination was found be negative. As the cytopenia of the patient deepened, the patient was accepted to have neutropenic fever and it was planned to start piperacillin-tazobactam 4 x 4.5 g/day and two units of erythrocyte replacement therapy. When the patient's history was questioned again, it was learned that she had a tick on her neck about three weeks ago and she had removed the tick herself; 4-5 days later she had the complaints of fever and flu like symptoms and also diarrhea complaints lasting for 3-4 days. Considering the current anamnesis and laboratory findings, the patient was thought to have CCHF and the patient was isolated. The serum sample taken from patient with an initial diagnosis of CCHF and sent to Department of Microbiology Reference Laboratory Public Health Agency of Turkey. The patient was referred to the Antalya Training and Research Hospital. The patient's CCHF serum result was positive. Ribavirin treatment was not initiated in the patient who was accepted to be in the convalescence period, piperacillin-tazobactam 4 x 4.5 g/day treatment was continued and supportive treatment was given. In the follow-up, as the patient's neutropenia, thrombocytopenia and lymphocytopenia still continuing, she was transferred to hematology clinic for malignancy examination and bone marrow biopsy performed by hematology and B cell ALL was diagnosed. She was accepted to be convalescent in terms of CCHF and chemotherapy was started for ALL treatment by hematology. The patient is still being followed up by the hematology clinic and allogenic hematopoietic stem cell tranplantation is planned for the patient.

When evaluating the returning traveler with fever, it is important to know which pretravel immunizations the patient received; which medications he or she took during travel; the likely pathogen exposures during travel; and the incubation interval between travel and onset of fever. A physical examination that includes a search for focal findings may narrow the list of possible infections. Fever compatible with a common illness that occurs in the United States (e.g., mononucleosis) should always be considered. If the patient has fever without a focus and a tropical infection is suspected, malaria, dengue fever, and typhoid fever are common causes. These infections may appear clinically similar, with symptoms of fever, headache, muscle pain, joint pain, and malaise, and decreased white blood cell and platelet counts. Malaria can usually be diagnosed with a thin blood smear. Dengue fever is a clinical diagnosis. Serologic testing for dengue virus immunoglobulin M and G and virus detection tests can be performed to confirm the diagnosis, but are not immediately available.

In malaria-endemic areas, the pandemic situation will very likely result in co-infection of COVID-19 and malaria, although reports to date are still few. Meanwhile, this disease will be challenging to diagnose in areas with low malaria prevalence because the symptoms closely resemble COVID-19. A 23-year-old male patient presented to the hospital with fever, anosmia, headache, and nausea 1 week before. He was diagnosed with COVID-19 and treated for approximately 10 days, then discharged to continue self-quarantine at home. 2 weeks later, he returned to the hospital with a fever raised intermittently every 2 days and marked by a chilling-fever-sweating cycle. A laboratory test for malaria and a nasopharyngeal swab for SARS CoV-2 PCR were conducted, confirming both diagnoses. The laboratory examination showed markedly elevated D-dimer. He was treated with dihydroartemisinin-piperaquine (DHP) 4 tablets per day for 3 days and primaquine 2 tablets per day for 14 days according to Indonesian National Anti-malarial Treatment Guidelines. After 6 days of treatment, the patient had no complaints, and the results of laboratory tests had improved. This report describes the key points in considering the differential diagnosis and prompt treatment of malaria infection during the pandemic of COVID-19 in an endemic country to prevent the worse clinical outcomes. COVID-19 and malaria may also cause a hypercoagulable state, so a co-infection of those diseases may impact the prognosis of the disease. This case report shows that considering the possibility of a co-infection in a COVID-19 patient who presents with fever can prevent delayed treatment that can worsen the disease outcome. Paying more attention to a history of travel to malaria-endemic areas, a history of previous malaria infection, and exploring anamnesis regarding the fever patterns in patients are important points in making a differential diagnosis of malaria infection during the COVID-19 pandemic." }, { "id": "pubmed23n0850_7266", "title": "Guillain-Barre syndrome following dengue fever and literature review.", "score": 0.012398902625859552, "content": "Dengue is an arboviral infection that classically presents with fever, joint pain, headaches, skin flush and morbilliform rashes.

In this case report, two cases of meningococcemia infected with serogroup C and Y of N.meningitidis rarely seen in our country were presented. First case was a two and a half year-old female patient who has admitted to our pediatric emergency unit with fever and rash spreading from lower extremities to her body. The patient had diffuse purpuric rash with generalized weakness and tendency to sleep at admission. The patient has been suspected as meningococcemia because of the skin rash, tendency to sleep and hypotension. Antibiotics treatment was started immediately and lumber puncture was performed.

Symptoms typically begin three to fourteen days after infection. These may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash. Recovery generally takes two to seven days. In a small proportion of cases, the disease develops into a more severe dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs. Dengue is spread by several species of female mosquitoes of the Aedes genus, principally Aedes aegypti. The virus has five serotypes; infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others.

The patient also reported a nonproductive cough, coryza, and fatigue. The patient's only risk factor for HIV infection was a history of unprotected intercourse with 5 girls. Physical examination was significant for fever, exudative tonsillopharyngitis, shotty cervical lymphadenopathy, and palpable purpura on both feet. Laboratory studies demonstrated lymphopenia and mild thrombocytopenia. Hemoglobin, serum creatinine, and urinalysis were normal. The following day, the patient remained febrile. Physical examination revealed oral ulcerations, conjunctivitis, and erythematous papules on the thorax; the purpura was unchanged. Serologies for hepatitis B, syphilis, HIV, and Epstein-Barr virus were negative. Bacterial cultures of blood and stool and viral cultures of throat and conjunctiva showed no pathogens. Coagulation profile and liver enzymes were normal. Within 1 week, all symptoms had resolved. The platelet count normalized. Repeat HIV serology was positive, as was HIV DNA polymerase chain reaction. Subsequent HIV viral load was 350 000, and the CD4 lymphocyte count was 351/mm3. HIV is the seventh leading cause of death among people aged 15 to 24 in the United States, and up to half of all new infections occur in adolescents. Our patient presented with many of the typical signs and symptoms of acute HIV infection: fever, fatigue, rash, pharyngitis, lymphadenopathy, oral ulcers, emesis, and diarrhea. Other symptoms commonly reported include headache, myalgias, arthralgias, aseptic meningitis, peripheral neuropathy, thrush, weight loss, night sweats, and genital ulcers. Common seroconversion laboratory findings include leukopenia, thrombocytopenia, and elevated transaminases. The suspicion of acute HIV illness should prompt virologic and serologic analysis. Initial serology is usually negative. Diagnosis therefore depends on direct detection of the virus, by assay of viral load (HIV RNA), DNA polymerase chain reaction, or p24 antigen. Both false-positive and false-negative results for these tests have been reported, further complicating early diagnosis. Pediatricians should play an active role in identifying HIV-infected patients. Our case, the first report of acute HIV illness in an adolescent, emphasizes that clinicians should consider acute HIV seroconversion in the appropriate setting. Recognition of acute HIV syndrome is especially important for improving prognosis and limiting transmission. It is imperative that we maintain a high index of suspicion as primary care physicians for adolescents who present with a viral syndrome and appropriate risk factors." }, { "id": "pubmed23n0877_9219", "title": "Domestic dengue infection with hemophagocytic lymphohistiocytosis successfully treated by early steroid therapy.", "score": 0.011333163069850594, "content": "A 34-year-old man, working at a park in Tokyo, Japan, was repeatedly bitten by mosquitoes while cutting grass.

Third case was a 46 years old, male patient who had been working in Uganda, and returned to Turkey two weeks ago. He had sudden onset of fever, headache, nausea and vomiting and impaired consciousness. His peripheral blood smear revealed ring-formed trophozoites and banana-shaped gametocytes of P.falciparum. Arthemeter plus lumefantrine therapy was started, however, he developed severe thrombocytopenia and jaundice under treatment. His general condition was detoriated and the patient lost his consciousness.

Typical very long and rambling question but not really too complicated... The patient is in heart failure with moderate ventricular dysfunction and also presents atrial fibrillation; she has criteria for anticoagulation, and between the two options that include acenocoumarol we are inclined to choose option 4, since it includes carvedilol, a drug that has been shown to increase survival in heart failure. Verapamil (and calcium antagonists in general) are contraindicated in systolic heart failure: they do not increase survival (they even increase morbidity and mortality) and specifically the non-dihydropyridines (verapamil and diltiazem) should not be associated with beta-blockers due to the increased risk of conduction system blockade.

A 78-year-old woman with a history of hypertension treated with amlodipine was admitted 3 months ago for heart failure and atrial fibrillation. She came to your office for a cardiological check-up. The discharge report shows the result of the echocardiogram showing moderate left ventricular dysfunction and the discharge treatment: amlodipine was discontinued and furosemide and enalapril were started. The patient reports feeling better, without fatigue and with less leg edema, but she is still not completely well. Physical examination showed no signs of heart failure, but her blood pressure and heart rate were 150/90 mmHg and 120 bpm, respectively. The ECG shows atrial fibrillation at 110-120 bpm. Which treatment is most likely to improve symptoms and reduce mortality from cardiovascular events?

The approach to pharmacologic treatment has become a combined preventive and symptomatic management strategy. Ideally, treatment should be initiated in patients at risk, preventing disease progression. In patients who have progressed to symptomatic left ventricular dysfunction, certain therapies have been demonstrated to improve survival, decrease hospitalizations, and reduce symptoms. The mainstay therapies are angiotensin-converting enzyme (ACE) inhibitors and beta-blockers (bisoprolol, carvedilol, and metoprolol XL/CR), with diuretics to control fluid balance. In patients who cannot tolerate ACE inhibitors because of angioedema or severe cough, valsartan can be substituted. Valsartan should not be added in patients already taking an ACE inhibitor and a beta-blocker. Spironolactone is recommended in patients who have New York Heart Association (NYHA) class III to IV symptoms despite maximal therapies with ACE inhibitors, beta-blockers, diuretics, and digoxin. Low-dose digoxin, yielding a serum concentration &lt;1 ng/mL can be added to improve symptoms and, possibly, mortality. The combination of hydralazine and isosorbide dinitrate might be useful in patients (especially in African Americans) who cannot tolerate ACE inhibitors or valsartan because of hypotension or renal dysfunction. Calcium antagonists, with the exception of amlodipine, oral or intravenous inotropes, and vasodilators, should be avoided in HF with reduced systolic function. Amiodarone should be used only if patients have a history of sudden death, or a history of ventricular fibrillation or sustained ventricular tachycardia, and should be used in conjunction with an implantable defibrillator [corrected].

A previously conducted randomized trial (RACE II) to assess heart rate goal in patients with AF showed no outcome difference between lenient and strict heart rate control; however, sufficient evidence to assess the impact on all-cause mortality was lacking. Physicians usually attempt to control heart rate control with agents such as beta-blockers (metoprolol, esmolol, propranolol), nondihydropyridine calcium-channel blockers (verapamil, diltiazem), or digoxin. All 3 classes of drugs are given intravenously (IV) for acute rate control and can be switched to oral therapy for chronic management. In patients with chronic heart failure with reduced ejection fraction, carvedilol therapy has shown significant improvement in left ventricular ejection fraction. Due to the negative inotropic properties of calcium channel blockers, physicians do not use these not preferred in such patients.

Of the 178 patients identified (82 males--46.1%, 96 females--53.9%, mean age 78 +/- 11 years) 163 (91.6%) were referred to Departments of General Medicine. The cause of heart failure was coronary artery disease in 88 (49.4%) patients, arterial hypertension in 40 (22.4%), primary cardiomyopathy in 28 (15.7%), valvular heart disease in 22 (12.3%). NYHA functional class was reported or deducible from the severity of dyspnea in 57 (32%) patients. In 8 (4.6%) patients symptoms or signs of heart failure were not reported.

First, this prescribing cascade potentially induced by ropinirole, as well as the increase in health care costs associated to iatrogenic admissions, is major preventable problem faced mostly by the geriatric population. Second, although OH associated with ropinirole has only been reported in patients treated for Parkinson's disease, this side effect should be considered when prescribing ropinirole for other indications, with cautious assessment of risks and benefits.

It was objectively shown to improve exercise capacity and to lengthen the time to symptom onset in patients with coronary artery disease. The most commonly reported side effects of ranolazine include dizziness, headache, constipation, and nausea. Here, we describe a case of bradycardia, hyperkalemia, and acute renal injury in the setting of ranolazine use. Our patient is an 88-year-old female who presented with abdominal pain, nausea, and vomiting. Her medical comorbidities included hypertension, diabetes, CAD, heart failure with preserved ejection fraction, paroxysmal atrial fibrillation, hypothyroidism, and a history of cerebrovascular accident without any residual deficits. Her prescription regimen included amlodipine, furosemide, isosorbide mononitrate, levothyroxine, metformin, omeprazole, and ranolazine. Physical examination was remarkable for bradycardia and decreased breath sounds in the left lower lung field. Laboratory studies were significant for a serum potassium level of 6.8 mEq/L and a serum creatinine level of 1.6 mg/dL. She was given insulin with dextrose, sodium polystyrene, and calcium gluconate in addition to fluids. Her bradycardia and renal function worsened over the next 24 hours. Ranolazine was discontinued. Metabolic derangements were treated appropriately. After 48 hours from presentation, potassium and renal function returned to baseline and her heart rate improved to a range of 60-100 bpm. She was discharged with an outpatient cardiology follow-up. Ranolazine treatment was not continued upon discharge. In summary, our case illustrates an association between ranolazine and renal failure induced hyperkalemia, leading to conduction delays in the myocardium. Though further studies are warranted, we suspect that this is a variant of the recently described BRASH syndrome. We propose that in cases such as ours, along with treatment of the hyperkalemia, medication review and removal of any offending agent should be considered." }, { "id": "pubmed23n0273_6468", "title": "Optimal management of older patients with atrial fibrillation.", "score": 0.009615384615384616, "content": "Long term oral warfarin should be administered to elderly patients with atrial fibrillation who are at high risk for developing thromboembolic stroke and who have no contraindications to anticoagulant therapy.

CASE REPORT An 88-year-old woman with a history of hypertension and diabetes presented to the emergency department with shortness of breath and new-onset atrial fibrillation. The physical examination revealed jugular vein distention, an irregular heart rate of approximately 140 beats/min, bilateral basal lung crackles, and no murmurs. One week before this presentation, she underwent electrocardiography, which showed she was in sinus rhythm, and transthoracic echocardiography, which indicated an ejection fraction of 65%. After hospital admission, she was started on beta-blockers for heart rate control and diuretics for heart failure management.

The therapeutic approaches to heart failure have undergone considerable changes during the last few years. The guidelines have to be updated almost yearly due to new results from prospective randomized studies. Although an agreement could be reached with respect to general measures and drug treatment, no agreement on mechanical devices, pacemakers and surgical interventions has been reached. The basis for medical treatment of chronic heart failure depends on diuretics, digitalis, ACE inhibitors, and beta-blockers. Calcium antagonists and other positive inotropic drugs, other than digitalis, should be avoided as far as possible. Thiazides, loop diuretics and aldosterone antagonists are needed for acute and chronic treatment of heart failure, alone or in combination (diuretic resistant heart failure!). Digitalis glycosides are needed in patients with atrial fibrillation with a fast ventricular rate or atrial flutter and in patients with systolic dysfunction, large hearts and symptomatic failure class NYHA III and IV. However, digitalis does not convert atrial fibrillation to sinus rhythm. Today there is no question that ACE inhibitors improve the prognosis of all patients with heart failure in all stages, if ejection fraction is reduced. Therefore, most patients after myocardial infarction or after having experienced pump failure due to myocarditis or cardiomyopathy are treated with ACE inhibitors and diuretics. The beneficial effects of ACE inhibitors seem to be most pronounced the worse the situation is. Relative risk reductions (mortality!) between 10% and 40% have been published depending on the severity of symptomatic left ventricular dysfunction. Those patients with high absolute risk have more to gain than those with low risk for any given \"risk reduction\", of course. Recent studies also indicate that most high risk cardiac patients profit from ACE inhibitors even if pump function is normal (i.e., patients with coronary heart disease, diabetes mellitus, cerebral vascular disease, hypertension) (15). AT1 antagonists can substitute for ACE inhibitors, if the latter are not tolerated due to cough. Up to now, beta-blocking agents apart from diuretics seem to be the best investigated drugs in heart failure. Large controlled studies with bisoprolol, carvedilol and metoprolol in addition to diuretics, digitalis and ACE inhibitors convincingly yielded positive results in chronic left ventricular failure patients. Reduction of mortality by 35% and even of sudden cardiac deaths by 40% have been proven beyond doubt. Thus, heart failure patients today should also receive beta-blocking agents in all stages of the disease.

Transient ischemic symptoms such as amaurosis fugax, episodes of blurred vision or diplopia may occur, either heralding visual loss or remaining isolated. In studies, the main predictors of PVL are jaw claudication, amaurosis fugax, lack of systemic \"B\" symptoms, a modestly increased ESR and a higher haemoglobin level. The evaluation of a GCA patient with PVL includes emergency fundoscopy completed by fluorescein angiography, immediate erythrocyte sedimentation rate, C-reactive protein, and complete blood count. Treatment is extremely urgent mainly because, if left untreated, GCA is associated with visual loss in the fellow eye within days in up to 50% of individuals. Treatment may begin with high-dose intravenous methylprednisolone, followed by oral prednisone administered at 1 mg/kg per day. Daily adjunctive aspirin orally may be added since it has been shown, in retrospective studies, to protect against stroke and visual loss.

As in 7 of them the initial diagnosis had proved erroneous, this study concerns the remaining 18 patients who together totalled 31 relapses after the correct diagnosis was made. Twenty relapses occurred early on, within 4 months of a change in treatment, and they corresponded to recurrent activity of the disease. Ten relapses occurred later on, after treatment had been discontinued or kept at maintenance dose level. The relapses appeared as early as the first year in 41 percent of the cases. The ENT region was affected in 61 percent of the patients. Nine relapses occurred in the absence of treatment, including 6 which took place 1 to 8 years after treatment. Three relapses occurred less than 3 months after a prednisone and oral cyclophosphamide therapy was initiated. Compared with the group of patients without relapse, those in the relapse group were younger, more often treated with azathioprine and cyclophosphamide administered intravenously, and followed up for a longer period; their probability of survival was also higher. In case of early relapse after withdrawal of treatment the mean duration of that treatment had been shorter than in the absence of relapse. None of the patients whose treatment had been stopped more than 20 months after its onset had an early relapse. These data prompted us to make the following proposals: initially, cyclophosphamide should be administered as bolus injections (the time required to obtain results is then shorter than with the oral route), and maintenance therapy should last at least 20 months. Azathioprine should be used only when cyclophosphamide is contra-indicated. The relative indications for intravenous and oral cyclophosphamide remain to be determined. Discontinuing all treatments is a difficult decision to make, but even then the patients should be under close supervision in view of the possibility of late relapses." }, { "id": "wiki20220301en115_376", "title": "Management of ulcerative colitis", "score": 0.009345794392523364, "content": "Oral anti-inflammatory drugs require four to six weeks to work.

In patients who respond clinically, the serum CK decreases before the weakness subsides; with relapse, the serum CK rises before weakness returns. Once the CK level normalizes and strength improves, typically several weeks or longer, one approach is to reduce the dosage gradually—by no more than 5 mg every 2 weeks—toward 20 mg daily.

She sought medical advice at a nearby dermatology clinic, where hepatic dysfunction was noted on blood testing. The patient was thus hospitalized the next day. Although CRP levels were significantly high, no sign of infection was observed and bone marrow cell differentiation was normal. Adult onset Still's disease was diagnosed based on the observation of persistent high fever &gt;39 degrees C, eruptions, increased leukocytes, pharyngeal pain, splenomegaly, hepatic dysfunction, negative autoantibody results from blood testing, and high serum ferritin levels. Administration of prednisolone 30 mg/day was initiated, but proved ineffective. Steroid pulse therapy was conducted, and the subject was transferred to our medical facility for continued treatment. Attempts were made to control the disease using combined steroid and cyclosporine administration; but exacerbation of high serum ferritin levels and hepatic dysfunctions were observed, so a second course of steroid pulse therapy was conducted. Symptoms improved temporarily, but steroid levels were difficult to reduce. Cyclosporine was therefore replaced by methotrexate, and administration of infliximab was initiated. In the course of treatment, administration of a sulfamethoxazole/trimethoprim combination was initiated, but was discontinued due to suspicion of drug-induced hepatic injury. A second administration of infliximab was conducted in late August, and rapid improvements in clinical symptoms and abnormal test values was observed. However, high fever and headache developed suddenly in early September. Based on the results of spinal fluid testing, blood and spinal fluid cultures and MRI of the head, Listeria meningoencephalitis was diagnosed. Diplopia and impaired consciousness occurred during the disease course, and formation of a brain abscess was observed on imaging. However, symptoms were controlled by long-term combination administration of ampicillin and gentamicin. Administration of infliximab was discontinued for treatment of adult onset Still's disease, and steroid levels were reduced following double-membrane filtration plasma exchange. On follow-up, no relapse of symptoms or abnormalities in blood test values were observed, so the subject was discharged from our medical facility in December 2005. In treatment for rheumatic diseases, a dramatic improvement in treatment results for pathologies displaying tolerance against conventional treatments has been acquired with the development of biological drugs. However, opportunistic infections represent a serious problem, and appropriate preventative measures are required.

This article provides practical advice for the management of patients with cirrhosis and acute kidney injury based on the best available published evidence. This best practice document is not based on a formal systematic review. This expert review was commissioned and approved by the AGA Institute Clinical Practice Updates Committee and the AGA Governing Board to provide timely guidance on a topic of high clinical importance to the AGA membership and underwent internal peer review by the Clinical Practice Updates Committee and external peer review through the standard procedures of Clinical Gastroenterology &amp; Hepatology. These Best Practice Advice (BPA) statements were drawn from a review of the published literature and from expert opinion. Since systematic reviews were not performed, these BPA statements do not carry formal ratings of the quality of evidence or strength of the presented considerations. BEST PRACTICE ADVICE 1: Acute kidney injury (AKI) should be diagnosed when the serum creatinine increases by ≥0.3 mg/dL within 48 hours or is ≥50% from baseline or when the urine output is reduced below 0.5 mL/kg/h for &gt;6 hours. BEST PRACTICE ADVICE 2: Preventive measures against the development of AKI in cirrhosis include (1) avoidance of potentially nephrotoxic medications like nonsteroidal anti-inflammatory drugs (NSAIDs), (2) avoidance of excessive or unmonitored diuretics or nonselective beta-blockade, (3) avoidance of large-volume paracentesis without albumin replacement, and (4) counseling patients to avoid alcohol use. BEST PRACTICE ADVICE 3: (A) Investigation is directed to determining the cause of AKI, which can be due to hypovolemic causes (volume responsive, and the most common cause of AKI in patients with cirrhosis); acute tubular necrosis; hepatorenal syndrome with AKI (HRS-AKI) (a functional renal failure that persists despite volume repletion); HRS with acute kidney disease, a type of functional renal failure of &lt;3 months- duration in which criteria for HRS-AKI are not met; or postrenal, which occurs only rarely. (B) The specific type of AKI should be identified through a careful history, physical examination, blood biochemistry, urine microscopic examination, urine chemistry (Na+ and urea) and selected urinary biomarkers, and renal ultrasound. BEST PRACTICE ADVICE 4: A rigorous search for infection is required in all patients with AKI. A diagnostic paracentesis should be carried out to evaluate for spontaneous bacterial peritonitis; blood and urine cultures and chest radiograph are also required. There is no role for routine prophylactic antibiotics in patients with AKI, but broad-spectrum antibiotics should be started whenever infection is strongly suspected. BEST PRACTICE ADVICE 5: When AKI is diagnosed, diuretics and nonselective beta-blockers should be held, NSAIDs discontinued, the precipitating cause of AKI treated, and fluid losses replaced, administering albumin 1 g/kg/d for 2 days if the serum creatinine shows doubling from baseline. Urine output, vital signs, and when indicated, echocardiography or CVP (if there is a pre-existing central line) should be used to monitor fluid status. BEST PRACTICE ADVICE 6: When the serum creatinine remains higher than twice the baseline value despite these measures, treatment of HRS-AKI should be initiated with albumin at a dose of 1 g/kg intravenously on day 1 followed by 20-40 g daily along with vasoactive agents (terlipressin; if terlipressin is not available, either a combination of octreotide and midodrine; or norepinephrine, depending on institutional preferences) and continued either until 24 hours following the return of the serum creatinine level to within ≤0.3 mg/dL of baseline for 2 consecutive days or for a total of 14 days of therapy. BEST PRACTICE ADVICE 7: Terlipressin should be initiated as a bolus dose of 1 mg every 4-6 hours (total 4-6 mg/d). The dose should be increased to a maximum of 2 mg every 4-6 hours (total 8-12 mg/d) if there is no reduction in serum creatinine at day 3 of therapy by at least 25% compared to the baseline value. Alternatively, clinicians can administer terlipressin by continuous intravenous infusion at a lower starting dose of 2 mg/d, which may reduce ischemic side effects and increase the dose gradually every 24-48 hours up to a maximum dose of 12 mg/d, or reversal of HRS. As per Food and Drug Administration restrictions, terlipressin should not be used in patients with a serum creatinine ≥5 mg/dL, or oxygen saturation of &lt;90%. BEST PRACTICE ADVICE 8: Oral midodrine when used should be initiated at doses of 7.5 mg and titrated upward to 12.5 mg 3 times daily with octreotide (starting with 100 μg and titrating upward to 200 μg subcutaneously 3 times daily). BEST PRACTICE ADVICE 9: Norepinephrine should be used as a continuous intravenous infusion at a starting dose of 0.5 mg/h and the dose increased every 4 hours by 0.5 mg/h to a maximum of 3 mg/h with the goal of increasing the mean arterial pressure by ≥10 mm Hg and/or the urine output to &gt;50 mL/h for at least 4 hours. BEST PRACTICE ADVICE 10: The risks of ischemic side effects of terlipressin and norepinephrine include angina and ischemia of fingers, skin, and intestine. These side effects may be lowered by starting at the lowest dose and gradually titrating upward. BEST PRACTICE ADVICE 11: Fluid status should be closely monitored because of the risk of pulmonary edema with excessive use of albumin. BEST PRACTICE ADVICE 12: Renal replacement therapy (RRT) may be used in the management of (A) AKI secondary to acute tubular necrosis; (B) HRS-AKI in potential candidates for liver transplantation (that is, RRT should not be used in patients with HRS-AKI who are not candidates for liver transplantation); and (C) AKI of uncertain etiology in which the need for RRT may be considered on an individual basis. BEST PRACTICE ADVICE 13: Transjugular intrahepatic portosystemic shunts should not be used as a specific treatment of HRS-AKI. BEST PRACTICE ADVICE 14: Liver transplantation is the most effective treatment for HRS-AKI. Pharmacotherapy for HRS-AKI before proceeding with liver transplantation may be associated with better post-liver transplantation outcomes. Selected patients with HRS-AKI may require simultaneous liver kidney transplantation based on updated Organ Procurement and Transplantation Network listing criteria." } ] } } }

It is often discovered incidentally when obtaining a complete blood count during an office visit. The etiology usually is not obvious, and additional investigation is required. Patients with platelet counts greater than 50 × 10(3) per µL rarely have symptoms. A platelet count from 30 to 50 × 10(3) per µL rarely manifests as purpura. A count from 10 to 30 × 10(3) per µL may cause bleeding with minimal trauma. A platelet count less than 5 × 10(3) per µL may cause spontaneous bleeding and constitutes a hematologic emergency. Patients who present with thrombocytopenia as part of a multisystem disorder usually are ill and require urgent evaluation and treatment. These patients most likely have an acute infection, heparin-induced thrombocytopenia, liver disease, thrombotic thrombocytopenic purpura/hemolytic uremic syndrome, disseminated intravascular coagulation, or a hematologic disorder. During pregnancy, preeclampsia and the HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome are associated with thrombocytopenia. Patients with isolated thrombocytopenia commonly have drug-induced thrombocytopenia, immune thrombocytopenic purpura, pseudothrombocytopenia, or if pregnant, gestational thrombocytopenia. A history, physical examination, and laboratory studies can differentiate patients who require immediate intervention from those who can be treated in the outpatient setting.

This case demonstrates that even with subtle deviations from typical ITP findings one must promptly reevaluate the diagnosis. This case also highlights the importance of peripheral smear review by an expert in pediatric hematopathology. A previously healthy 10 year-old Asian boy presented with 2 months of easy bruising. Review of systems was negative for any constitutional symptoms. On examination, he appeared well but had numerous large ecchymoses. He had no appreciable lymphadenopathy or splenomegaly. The liver was palpable 1.5 cm below the costal margin. A complete blood count (CBC) showed: platelets = 17 × 109/L, hemoglobin = 128 g/L, white blood cell count = 5.43 × 109/L, and neutrophils = 1.63 × 109/L. A blood smear was reported as normal. Urate was 370 umol/L and lactate dehydrogenase (LDH) was 803 U/L. The child was admitted with a presumptive diagnosis of immune thrombocytopenic purpura (ITP) and treated with intravenous immunoglobulin. The following day, the blood smear was reviewed by a hematopathologist who identified blasts. A bone marrow aspiration (BMA) confirmed the diagnosis of precursor B-cell acute lymphoblastic leukemia. In children presenting with suspected ITP, leukemia should always be considered. A BMA was historically performed on all patients with presumed ITP to rule out leukemia. In 2011, the American Society of Hematology (ASH) stopped recommending routine BMA in patients suspected of having ITP. ASH advises in cases with unusual findings on history, physical examination or CBC, it is reasonable to perform a BMA. Our patient had mild hepatomegaly, which may have qualified him for a BMA. He also had an elevated LDH and urate, which are not listed as criteria for BMA by ASH but were considered atypical for ITP by the clinical team. A literature search did not reveal any primary data assessing these markers. While corticosteroids are a first line treatment in ITP, they must be reserved for when clinicians are confident that the patient does not have leukemia.

The most appropriate laboratory tests can then be ordered. Routine screening tests include a complete blood cell count, platelet count, and evaluation of a peripheral blood sample, a prothrombin time, and an activated partial thromboplastin time. Thrombocytopenia may result from idiopathic thrombocytopenic purpura, disseminated intravascular coagulation, or, less commonly, acute leukemia, aplastic anemia, thrombotic thrombocytopenic purpura, or a particular drug that a patient is taking. Again, the patient's history, physical findings, and evaluation of a well-prepared peripheral blood smear will be helpful in determining the cause of the patient's thrombocytopenia. An isolated prolongation of the activated partial thromboplastin time may result from low levels of factors VIII, IX, or XI. A slightly prolonged activated partial thromboplastin time and a moderate decrease in factor VIII may reflect von Willebrand disease or the \"carrier\" state for hemophilia A. In women a greatly prolonged activated partial thromboplastin time and very low levels of factor VIII (&lt; 3%) most often result from an acquired factor VIII inhibitor (autoantibody against factor VIII) or from severe (type III) von Willebrand disease. If von Willebrand disease is suspected (because of menorrhagia with or without other mucous membrane bleeding, a positive family history, and a prolonged activated partial thromboplastin time), more specific laboratory tests for this disease should be done. These include assays of factor VIII, von Willebrand factor antigen, von Willebrand factor activity (measured by the ristocetin cofactor assay), and template bleeding time. In von Willebrand disease the defect is in von Willebrand factor. The affected individual may have subnormal levels of structurally and functionally normal von Willebrand factor (this is called \"classic\" or type I von Willebrand disease) or may produce von Willebrand factor that is structurally and functionally abnormal (von Willebrand disease type 2). Individuals who inherit a gene for von Willebrand disease from both parents have severe (type 3) von Willebrand disease and will have extremely low levels (&lt; 3%) of von Willebrand factor and factor VIII and will have a very prolonged bleeding time. In most populations type I disease is the most common form, whereas type 3 is the least commonly encountered form. It should be noted that levels of von Willebrand factor can be influenced by the patient's blood type (persons who have blood type AB have 60% to 70% higher levels than do persons who have blood type O) and can be elevated during pregnancy, stress, and hyperthyroidism. The two major functions of von Willebrand factor are to serve as a \"bridge\" between platelets and injury sites in blood vessel walls and to protect circulating factor VIII from rapid proteolytic degradation. Thus, if a patient has either too little or functionally abnormal von Willebrand factor, the bleeding time will be prolonged and factor VIII will be decreased (because it is not being protected by von Willebrand factor). It should be determined which type of von Willebrand disease a particular patient has because treatment depends on type. Multimeric analysis of von Willebrand factor can be done with use of sodium dodecyl sulfate gels, radiolabeled antibody to von Willebrand's factor, and autoradiography. This will allow visualization of the multimeric structure of von Willebrand factor. In type I disease all bands are present, whereas in the type 2 variants 2A and 2B no high-molecular-weight multimers are seen.

It represents the acquired megakaryocytic thrombocytopenia with the shortened life of platelets because of immunologic damage (antibodies absorbed by platelets). In the case of this acquired hemorrhagic disorder, in spite of compensatory increased function of the bone marrow, there is a reduced number of platelets because of their increased destruction by the reticuloendothelial system (destructive thrombocytopenia). There are three forms of ITP: acute, chronic and intermittent. The acute form occurs in 80-90% of cases with bleeding episodes lasting a few days or weeks, but no longer than 6 months. The chronic form occurs in 10-15% of children, while the rarest-intermittent form is characterized by periods of normalization in regard to the number of platelets but also with relapse in intervals of 1-3 months. The disease is caused by an immunological disorder in the sense of an imbalanced immune response. Immunologic damages of platelets cause shortening of the opsonized platelets life span. The most frequent platelet opsonins are the immumoglobulin G (IgG) antibodies directed at the platelet membrane in the form of autoantibodies, alloantibodies or possibly absorbed antigen caused by microorganism infection or drug intake. It is typical for the phenomenon of bleeding that it starts suddenly and without any other sign of illness. The most frequent acute form appears between the second and fourth year, and is characterized by seasonal occurrence usually after acute viral infections. Children older than 10 years of age, like adults, often have the chronic form associated with other immunologic disorders. The disease affects girls more often than boys (about three times more often) with moderate and constant increase of antiplatelet antibodies. Hemorrhagic manifestations include: petechiae, purpura, epistaxis, gastrointestinal and genitourinary bleeding. They depend on the grade of thrombocytopenia, although there is no strict correlation between the number of platelets and volume of bleeding. Low mortality of the acute ITP is almost exclusively due to intracranial hemorrhage. LABORATORY STUDIES: Thrombocytopenia represents a decrease in the number of blood platelets being a basic abnormality of the blood count. The half-life of platelets in ITP is shortened. Detection of antiplatelet antibodies is connected with technical difficulties, so they are established in about 30% of cases. Bleeding time is prolonged and so is the coagulum retraction which may be completely missed. The Rumpel-Leede test is positive. Clinical differentiation of drug-induced thrombocytopenia is not possible. However, other differential diagnostic possibilities are thrombotic-thrombocytopenic purpura and hemolytic-uremic syndrome. A child with aplastic anemia or acute leukemia, beside thrombocytopenia, has a characteristic finding of white and red blood cell count. Thrombocytopenia with absent radii syndrome is associated with skeletal system abnormalities. New knowledge about the role of the immune system in ITP determines the modern therapeutic modalities. In cases of acute ITP in children, there are two therapeutic options or therapies of choice: corticosteroids and high doses of intravenous immunoglobulin. Immunosupressive therapy means anti Rh(D) immunoglobulin, cyclosporine, cytostatics, danazol, loaded platelets. In cases of distinctive hemorrhagic syndrome there are also indications for platelet transfusion. Nowadays splenectomy is more restricted, because one third of cases is unsuccessful, whereas plasmapheresis is rarely used in children because of possible complications. ITP is the most frequent hemorrhagic disease in children. The disease is basically caused by an immunologic disorder with platelet destruction due to increased immunoglobulin on their membrane.

In this clinical case, we are presented with a woman who rapidly presents dyspnea with hypoxemia, a picture compatible with pulmonary thromboembolism. The prothrombin time of 90% and the aPTT with a ratio of 2, is translating a coagulation problem; and antiphospholipid antibodies can be detected through the prolongation of phospholipid-dependent coagulation tests, [HIDDEN]. On the other hand, although factor V Leiden has been identified as a common cause of familial thrombosis, it would not alter the clotting time. In the case of hemophilia there would be a problem in blood coagulation but it is not a frequent cause of thromboembolism. Finally, although acute pericarditis could manifest itself in 4 days and with tachycardia, the rest of the symptoms or analytical parameters are not characteristic.
A 45-year-old woman with no history of interest consults for dyspneic sensation of about 4 days of evolution. Examination shows rhythmic tachycardia, without murmurs and pulmonary auscultation is normal. Arterial blood gases showed a pO2 of 70 mmHg and a pCO2 of 32 mmHg. Hemogram, renal and hepatic function are normal. Prothrombin time 90%, activated partial thromboplastin time (APTT) ratio of 2 to control (N <1.2). Which of the following is the most likely diagnosis?

Acquired von Willebrand disease associated with autoimmune disease in addition to pulmonary hypertension during emergency room presentation is a rare condition. To the best of our knowledge, this is the second case reported in the literature treated with success; the first one was reported in 1987. A 28-year-old mestizo man with a 3-year history of inflammatory arthritis was admitted to our hospital. An overlap of rheumatoid arthritis with systemic lupus erythematosus was suspected; therefore methotrexate was initiated, and later changed to leflunomide because of liver toxicity. Prothrombin time, international normalized ratio and activated partial thromboplastin times were normal (11/10.4 seconds; 1.2; 31.1/26.9 seconds, respectively), von Willebrand factor activity was observed with low ristocetin cofactor at 33.6UI/dL, high von Willebrand factor antigen &gt;200UI/dL, and a low von Willebrand factor: ristocetin cofactor to von Willebrand factor antigen ratio.

Cold, pale and mottled skin was also observed. He was then transferred to the intensive care unit. The placement of a pulmonary artery catheter was made. The initial patterns showed a precapillary pulmonary hypertension; acute pulmonary embolism was the first choice for diagnosis. Pulmonary angiography was conducted, and when no clot was discovered, pulmonary artery hypertension associated with connective tissue disease was considered. Serum protein electrophoresis confirmed the presence of a massive polyclonal hypergammaglobulinemia, and no paraproteinemia or monoclonal cell population was found from the electrophoretic pattern of the patient's plasma. Hypergammaglobulinemia was the cause of hyperviscosity syndrome associated with autoantibodies. Three sessions of plasma exchange therapy were made, and clinical improvement was observed. He was then discharged from the intensive care unit and hospital, respectively. He is now attended by an external consult and has no respiratory symptomatology.

Basically two types of DIC are distinguished: (1) chronic (compensated) - with alteration of laboratory values and (2) acute (non-compensated) - with severe clinical manifestations: bleeding, shock, acute renal failure (ARF), transient focal neurologic deficit, delirium or coma. Chronic DIC related to metastatic neoplasia is caused by pancreatic, gastric or prostatic carcinoma in most of the cases. Incidence rate of DIC is 13-30% in prostate cancer, among those only 0.4-1.65% of patients had clinical signs and symptoms of DIC. In other words, chronic DIC is developed in one of eight patients with prostate cancer. DIC is considered as a poor prognostic factor in prostatic carcinoma. The similar clinical and laboratory findings of TTP-HUS (thrombotic thrombocytopenic purpura - hemolytic uremic syndrome) and DIC makes it difficult to differentiate between them. A 71 years old male patient with known chronic obstructive pulmonary disease, benign prostatic hyperplasia, significant carotid artery stenosis, gastric ulcer and alcoholic liver disease was admitted to another hospital with melena. Gastroscopy revealed intact gastric mucosa and actually non-bleeding duodenal ulcer covered by clots. Laboratory results showed hyperkalemia, elevated kidney function tests, indirect hyperbilirubinemia, increased liver function tests, leukocytosis, anemia, thrombocytopenia and elevated international normalized ratio (INR). He was treated with saline infusions, four units of red blood cells and one unit of fresh frozen plasma transfusions. Four days later he was transported to our Institution with ARF. Physical examination revealed dyspnoe, petechiae, hemoptoe, oliguria, chest-wall pain and aggressive behavior. Thrombocytopenia, signs of MAHA (fragmentocytes and helmet cells in the peripheral blood), normal INR, elevated lactate dehydrogenase (LDH) and ARF suggested TTP-HUS. Hemodialysis and six plasmaferesis (PF) were carried out. After the fifth PF, skin manifestations of thrombotic microangiopathy occurred on the feet. Clotting analysis revealed elevated D-dimer (&gt;5 μg/mL), normal fibrinogen (3.2 g/L), a slightly raised INR (1.36) and activated partial prothrombin time (APTT) (45.8 sec), normal reticulocyte (57 G/L) and a slightly low platelet count (123 G/L), which proved to be chronic DIC. Therapeutic dose of low-molecular-weight heparin (LMWH) was started. Elevated prostate-specific antigen (PSA) (109.6 ng/mL) suggested prostatic carcinoma. Prostate biopsy revealed adenocarcinoma (Gleason: 4+4 for left lobe and 3+3 for right lobe). Elevated alkaline phosphatase suggested metastases in the bone, which were confirmed by bone scintigraphy. Combined androgen blockade (CAB) was started. After three months follow-up our patient's status is satisfactory. PSA is in the normal range (4.6 ng/mL). Thrombocytopenia of uncertain origin with normal or raised INR, APTT, elevated D-dimer, normal fibrinogen and reticulocyte count prove the diagnosis of chronic DIC. This process warrants searching for metastatic neoplasia. Due to the relatively low serum levels of circulating procoagulant factors (e.g. tissue factor), therapeutic dose of LMWH can be used with good efficiency in chronic DIC with low risk of bleeding. Severe DIC as a complication of metastatic prostate cancer can be treated by androgen deprivation therapy (ADT) or CAB in combination with ketokonazole and concomitant use of supportive treatment.

The differential diagnosis in prolonged aPPT with a normal prothrombin time (PT) includes factor deficiencies, lupus anticoagulant or heparin therapy. The first step to distinguish between factor deficiency and the presence of an inhibitory substance is to perform a mixing test, in which patient plasma and normal plasma are mixed and aPTT measured; correction of prolonged aPTT suggests a factor deficiency while persistent prolongation indicates the presence of an inhibitor.

We conclude that patients with aPL who show APC-R phenotype due to a low APTT ratio without the factor V Leiden mutation can be classified into two groups: true and spurious APC-R phenotype.

To test the contribution of such new markers, we reviewed the records of patients having antiphospholipid antibodies detected between 1996 and 1997. One hundred and twenty four patients, having at least one of these two aPL: lupus anticoagulant (LA), anticardiolipin antibodies (aCL), or one of these two anti-proteins: anti-beta 2glycoprotéin I antibodies (anti-beta 2GPI) or anti-prothrombin antibodies (aPT), were studied. LA was detected by a PTT-LA technique and aCL, anti-beta 2GPI and aPT by ELISA-sandwich techniques. For each patient we recorded sex, age, personal and familial history of thrombosis, fetal losses and systemic disease, the reason of aPL detection, the final diagnosis, activated partial thromboplastin time (aPTT), platelets count and type of aPL. The population was composed of 77 women (62%) and 47 men (38%) with a mean age of 54 years [12-92 years]. A thrombocytopenia was strongly correlated to aCL presence (OR = 6.15 et p = 0.03). The reason of aPL detection was venous thrombosis, recurrent fetal losses, systemic disease, infectious disease or fortuitous discovery of a prolonged aPTT. The final diagnosis was a systemic disease in 57% of cases, an infectious disease in 14.5%, a thrombosis in 4.5% and a neoplasia in 3%. LA was detected in 54% of patients, aCL in 39.5%, anti-beta 2GPI in 23% and aPT in 31%. No relationship between the aPTT value and the type of aPL could be established. Our study shows that familial histories of venous thrombosis or systemic disease are useful to enhance antiphospholipid antibodies detection; that LA is mostly associated to systemic and infectious diseases; that aCL and anti-beta 2GPI are predominant in case of venous thrombosis and that thrombocytopenia has to enhance aCL detection and the discussion about a possible APS." }, { "id": "pubmed23n1108_4052", "title": "Acquired hemophilia: clinical case of hemorrhage caused by inhibitors against factor VIII.", "score": 0.009433962264150943, "content": "Acquired hemophilia is caused by antibodies against coagulation factors, especially against factor VIII.

Dendritic corneal ulcer is typical of herpes simplex keratitis. It presents with pain, not too striking, and scarce or absent red eye. There are ulcers resembling dendrites that may confuse us in the diagnosis. These pseudodendrites are found in herpes Zoster and in corneal abrasions in resolution. Although in practice we should pay attention to the shape of the dendrite (the true dendrite is deeper and has terminal bulbs at the end of each branch), and pay attention to the evolution of the pain (in the pseudodendrite after abrasion the pain should improve), when answering a MIR question it is simpler: if it is a dendrite, the first thing we have to think is herpes. Fungal and bacterial keratitis have corneal infiltrates. And glaucomatocyclitic crisis (Posner Schlossman syndrome) is a type of idiopathic hypertensive anterior uveitis, which does not present with ulceration.

The patient reported exposure to plant debris while performing yard work and also water exposure while cleaning his coral fish tanks. Clinical examination revealed bilateral epitheliopathy progressing to frank epithelial defects with underlying stromal necrosis 6 days after exposure. Empiric topical antibiotic drops were initiated, but multiple cultures, corneal biopsy, and confocal microscopy were all negative for an infectious agent. Over a 2-week period, the epithelial defects worsened and a suspicion for a toxic etiology was raised. The patient later recalled rubbing his eyes after exposure to Epipremnum aureum (Golden Pothos/Devils Ivy) sap. He was thus treated conservatively with artificial tears, topical corticosteroids, and amniotic membrane.

Initially the patient received 1 course of cladribine upon which the disease went into complete remission. 6 weeks ago a relapse was diagnosed and combination therapy with cladibrin and rituximab was initiated. Now the patient presented to the emergency room with shortness of breath and pain when breathing. In the chest x-ray, patchy infiltrates and pleural effusions were found on both sides. The subsequently performed computed tomography showed bilateral compactions with an Halo suspicious for fungal infiltrates. Upon admission to the hospital, an empirical antibiotic therapy with clarithromycin and piperacillin/tazobactam was initiated, which was later escalated to meropenem and linezolid. Additionally, an antifungal therapy with voriconazole was started and later switched to liposomal amphotericin B. At his admission, a positive aspergillus antigen could be detected in the microbiological laboratory. Under antimycotic treatment the aspergillus antigen was repeatedly negative. The patient presented with pronounced cytopenias and after a switch of therapy to vemurafenib and filgrastim, the hematopoiesis could only be stimulated insufficiently. The patient was transferred to the intensive care unit three days after admission with severe respiratory failure. He died on day 8 after admission. AUTOPSY AND DIAGNOSIS: Diagnosis was consistent with relapse of hairy cell leukemia with positive BRAF mutation and a bone marrow infiltration &gt; 80 %. Autopsy revealed a significant hepato-splenomegaly, a lack of erythro-, granulo- and thrombopoiesis. Clots interspersed with fungal hyphae were found in both lungs and an infarction of the spleen with evidence of fungal hyphae was detected. The cultural findings post mortem on yeast or mold were negative. Patients with refractory hairy cell leukemia and prolonged neutropenia are at increased risk for systemic fungal infections. Therefore, prohylactic antimycotic therapy should be considered early in this group of patients. The therapeutic approach of vemurafenib in treatment-refractory hairy cell leukemia is promising and offers an additional treatment option.

Prospective study conducted at 3 medical intensive care units at the Viennese General Hospital, a tertiary care medical university teaching hospital in Vienna, Austria. One hundred one patients who received mechanical ventilation and who met the criteria for having ventilator-associated pneumonia. Fiberoptic bronchoscopic examination was performed, and bronchoalveolar samples were collected. Samples were analyzed immediately by a single technician. Minimum inhibitory concentrations were determined for imipenem, cephalosporins (cefepime and cefpirome), ciprofloxacin, and piperacillin-tazobactam, and drug resistance rates were calculated. These drug resistance rates were translated into the likelihood of inadequate therapy (LIT; the frequency of inadequately treated patients per antibiotic and drug-resistant strain), cumulative LIT (the cumulative frequency of inadequately treated patients), and syndrome-specific LIT. Among the 101 bronchoalveolar samples, culture yielded significant (at least 1 x 10(4) colony-forming units per mL) polymicrobial findings for 34 and significant monomicrobial findings for 31; 36 culture results were negative. Of the isolates from patients with ventilator-associated pneumonia who had monomicrobial culture findings, 33% were gram-positive bacteria and 20% were gram-negative bacteria. LIT suggested that 1 of 2 patients was treated inadequately for Pseudomonas aeruginosa infection. The LIT for patients with ventilator-associated pneumonia revealed that the rank order of antibiotics for appropriate therapy was (1) imipenem, (2) cephalosporins, (3) ciprofloxacin, and (4) piperacillin-tazobactam. These calculations were based solely on microbiological data.

While in Arizona, he experienced cough and hemoptysis and was diagnosed as pulmonary coccidioidomycosis. He was treated with itraconazole for two months and he had no symptoms for 3 years. He then returned to Turkey and 2 months after his return to Turkey, he was admitted to another hospital in Istanbul with dyspnea and diagnosed as hydro-pneumothorax, and pleural fluid obtained from the inserted chest tube was found to be purulent. One gram of BID amoxicillin-clavulanate was given. Physical examination on admission revealed a purulent drainage on the right side chest tube, a temperature of 38.5°C and decreased breath sounds on the right lung. Piperacillin-tazobactam 3 x 4.5 g intravenous and fluconazole 400 mg intravenous once daily were started. Human immunodeficiency virus test was negative.

The microscopic examination of 15% KOH preparations of pleural fluid specimens revealed septate hyphae which appear to be in the early stages of forming arthroconidia.

A compromised mental status (e.g. alcoholism, sedatives, stroke) and esophageal dysfunction (e.g. herniation, vomiting) are important risk factors. Aspiration pneumonia presents as a subacute disease and is usually not distinguishable from other causes of pneumonia, until typical radiological signs of cavitation and putrid sputum appear 8 to 14 days after the initial event of aspiration. Anaerobic bacteria play a pivotal role in an almost exclusively mixed spectrum of causative organisms. Aerobic pathogens are also frequently isolated, but whether they are an active part of infection or merely represent colonizers remains unclear in many instances. Differential diagnosis includes bronchial neoplasms, either as necrotizing carcinoma or as the cause of poststenotic cavernous pneumonia, other infectious diseases like tuberculosis, Pneumocystis carinii pneumonia or endocarditis with septic metastases, and lung artery embolism or vasculitis (M. Wegener). Fiberoptic bronchoscopy is extremely helpful in determining cause and etiology of the disease and should be carried out in all patients presenting with cavernous lung lesions. Bacteriological sampling should be performed using protected specimen brushing (PSB) technique. Broncho-alveolar lavage might serve as a less expensive but also less sensitive alternative measure.

Etiology of pneumonia was established in 16 episodes (53%). Fiberoptic bronchoscopy was the most useful technique (83% of positive diagnoses) followed by blood cultures (38%). Two patients were diagnosed of aspergillosis at autopsy. Pneumococcus was the most frequent agent (5 cases) followed by Pseudomonas aeruginosa (4), Pneumocystis carinii (2) and Aspergillus fumigatus (2). One out of the two patients with P. carinii pneumonia had received fludarabin and the remaining was treated with prednisone for long time.

All children hospitalized between 2007 and 2010 at the Mayo Clinic Children's Hospital, a 120-bed facility within a larger adult hospital in Rochester, Minnesota. We calculated antimicrobial utilization rates in days of therapy per 1,000 patient-days. Details of vancomycin and cefepime use in 2010 were abstracted by chart review. Two pediatric infectious disease physicians independently assessed appropriateness of antibiotic use. From 2007 to 2010, 9,880 of 17,242 (57%) hospitalized children received 1 or more antimicrobials. Antimicrobials (days of therapy per 1,000 patient-days) used most frequently in 2010 were cefazolin (97.8), vancomycin (97.1), fluconazole (76.4), piperacillin-tazobactam (70.7), and cefepime (67.6).

Allergy prevention in non-breastfed infants at risk: There are studies showing that fully hydrolyzed formula can reduce the risk of allergic reactions, especially atopic dermatitis, in high-risk non-breastfed babies. Some recommendations for high-risk non-breastfed infants support feeding up to 4 to 6 months with hydrolyzed formulas. Further research is needed on this subject. Soy formulas failed to prevent allergy in high-risk infants. • In case of cow's milk allergy symptoms in breastfed babies: Although a small amount of food allergens may be present in the milk, mothers should be encouraged to continue breastfeeding while avoiding consumption of cow's milk and products. • In case of cow's milk allergy symptoms in non-breastfed babies: Under six months of age, extensively hydrolyzed formula is suitable for most cases of cow's milk allergy, except for severe clinical conditions, which require amino acid formulas. Over six months, soy formulas can be considered. Exposure to solid foods: The current recommendations are to start on solids at the age of 4-6 months and there is no recommendation for avoiding known allergens, despite family history. Later introduction of peanut, fish or egg does not prevent, and may even increase, the risk of developing food allergy.

Whereas toddlers and children with food allergy or pseudo-allergy present with similar symptoms as adults, two different forms have been identified in the newborn and infant period. One can occur as allergic colitis in breast or bottle fed infants. In breast fed infants the bloody mucoid stools are produced because of an allergic reaction of the colonic mucosa to foreign proteins which are delivered to the baby via breast milk. In bottle fed infants the given foreign protein itself can trigger the allergic reaction. The clinical, endoscopical and histological appearance is similar to that of ulcerative colitis. Elimination of foreign proteins from the diet of the mother or in bottle fed infants from the child is the therapy of choice. The second manifestation of food allergy in this age group is the cow's milk protein intolerance with predominantly gastrointestinal symptoms such as vomiting, diarrhea and failure to thrive. The diagnosis is based on the clinical picture alone. The usual laboratory tests don't discriminate enough and can therefore not confirm the diagnosis. Elimination of the affecting protein and replacement by a semi-elementary diet are recommended for therapy. The prevention of allergies by dietetic means has become of great importance since it was possible to identify newborns at risk for allergies. The prolonged breast feeding and the late introduction of solids later than the sixth month of life is the preventive measure. \"Hypoallergenic\" formulae are not recommended because not enough solid data are available to confirm their preventive effect." }, { "id": "pubmed23n0739_17500", "title": "[Association of dietary patterns and food allergy in infants during the first year of life].", "score": 0.014288630332720964, "content": "There is controversy about the effect of dietary patterns during the first year of life and the occurrence of food allergy.

At present ther is evidence that the mode of early infant feeding influences the development of food allergy, whereas daily exposure to inhalant allergens and daily exposure to tobacco smoke is found to be associated with an increased risk of recurrent wheezing/asthma and inhalant allergy. In infants with atopic predisposition (first-degree relatives), exclusively breastfeeding &gt; or = four months is found associated with a significant reduction of the cumulative prevalence of cow's milk allergy/intolerance (CMA/CMI) during the first 1-2 years of age.

Partially hydrolysed formulas (pHF) may be effective in allergy prevention, but due to drawbacks of study design and lack of documentation pHF cannot be recommended at present. The results of studies comparing the preventive effect of eHF and pHF are awaited. The protective effect on the development of cow's milk allergy is a real prevention and not only a postponement of the onset of symptoms. No studies have demonstrated a preventive effect of dietary measures as regards asthma/inhalant allergy, at present until the age of four years. As no studies concerning the preventive effect of avoidance of milk and other foods after the age of 4-6 months of life have been performed, recommendation of preventive elimination diets beyond this age is empirically based. In order to reduce the costs, to minimize the risk of stigmatisation and the risk of malnutrition it is important to avoid unnecessary restrictive and prolonged diets. A diet period of 4-6 months seems sufficient in most infants. At present eHF are recommended for avoidance of cow's milk. Some high risk infants may benefit from maternal diet during lactation, but there is no documented beneficial effect of maternal diet during pregnancy." }, { "id": "pubmed23n0089_19498", "title": "[Incidence and symptoms of cow's milk protein intolerance following acute gastroenteritis in young infants.

The experts agreed that CMPA diagnosis should be based on symptomatic evaluation and diagnostic elimination diet as followed by implementation of an open challenge test after disappearance of symptoms and confirmation of CMPA diagnosis in re-appearance of symptoms. For breastfed infants, differential diagnosis involves withdrawal of cow's milk-containing products from the mother's diet, while calcium supplements and appropriate dietary advice are given to mothers to prevent nutritional deficiency. For infants not breastfed exclusively, cow's milk-based formula and any complementary food containing cow's milk protein (CMP) should be avoided. The first line treatment should be extensively hydrolyzed formula (eHF) with use of amino acid-based formula (AAF) in severe cases such as anaphylaxis, enteropathy, eosinophilic esophagitis and food protein induced enterocolitis along with cases of multiple system involvement, multiple food allergies and intolerance to eHF. Introduction of supplementary foods should not be delayed in CMPA, while should be made one by one in small amounts and only after the infant is at least 17 weeks of age. Infants who are at-risk can be identified by family history of atopic disease. Exclusive breastfeeding for 4-6 months (17-27 weeks) is recommended as the best method of infant allergy prevention. There is no evidence that modifying the mother's diet during pregnancy and/or breast-feeding and delaying solid or even potentially allergic foods beyond 4-6 months in infants may be protective against allergy among at-risk infants. When exclusive breastfeeding is not possible, at-risk infants should get a partially or extensively hydrolyzed formula (pHF or eHF) to prevent allergy until risk evaluation by a health professional. In conclusion, the present consensus statement provides recommendations regarding diagnosis, prevention and management of CMPA in infants and children in Turkey, and thus expected to guide physicians to optimize their approach to CMPA and decrease burden of the disease on infants and their caregivers." }, { "id": "pubmed23n0102_1105", "title": "Allergy to cow's milk in the first year of life and its prevention.", "score": 0.010609857978279031, "content": "Cow's milk allergy in the first year of life is one of the most common problems faced by pediatricians. Both over and under diagnosis is seen. Cow's milk allergy, which is IgE-mediated should be differentiated from milk intolerance due to lactase deficiency or other causes. Cow's milk allergy may effect the gastrointestinal tract, respiratory tract, skin or blood. Anaphylaxis may occur. Diagnosis is made primarily on clinical grounds but skin tests and/or RAST are of value. Elimination and subsequent challenge confirms the diagnosis but challenge is not always necessary. Challenge should not be performed if there is evidence of anaphylaxis. Avoidance is the mainstay of treatment and breastfeeding is the optimal choice. Since antigenically intact cow's milk protein can pass into the breast milk, the mother should avoid excessive intake of milk products herself while breast feeding. Alternatives to breast milk such as soy formulas or hydrolysed casein or whey formulas may be used. Twenty-five percent of milk-sensitive infants are also allergic to soy protein. Hydrolysed casein formulas are more hypoallergenic but are expensive and less palatable. Hydrolysed whey formula, which is comparable in expense to soy formulas but is less allergenic, may prove of value in the management of the milk-allergic infant as well as for prophylaxis in infants from susceptible parents. Parents of infants born to families with bilateral atopic histories may be able to prevent milk allergy by using dietary manipulations which include decreased prenatal maternal milk intake and while breast feeding as well as careful avoidance of milk products in the infant's diet during the first year of life." }, { "id": "pubmed23n0751_23062", "title": "Nutrition, growth, and allergic diseases among very preterm infants after hospital discharge.", "score": 0.009900990099009901, "content": "The aims of this PhD thesis were: 1. Primarily to investigate the effect, of adding human milk fortifier to mother's milk while breastfeeding very preterm infants after hospital discharge, on growth until 1 year corrected age (CA) 2. Secondarily to describe breastfeeding rate and factors associated with breastfeeding among very preterm infants at hospital discharge. 3. To describe possible feeding-problems during the intervention-period, and allergic diseases during the first year of life, among very preterm infants related to their nutrition after hospital discharge. 4. To describe the content of macronutrients in human milk from mothers delivering very preterm. This PhD thesis is based on a prospective, randomized, and controlled interventional birth cohort study. A total of 633 very preterm infants with a gestational age (GA) ≤ 32 + 0 weeks were recruited consecutively from July 2004 until August 2008 of whom 157 were excluded due to diseases or circumstances influencing nutrition. Further 156 refused participation in the interventional part of the study, but data on breastfeeding, weight, and some epidemiological data until discharge were available. Results on breastfeeding rate at discharge were therefore based on data from 478 infants, and parents of 320 infants accepted participation in the intervention study. Of these 320 infants, 207 were exclusively breastfed and they were shortly before hospital discharge randomized to either breastfeeding without (group A) or with fortification (group B) until 4 months CA. Infants (n = 113) who were bottle-fed at discharge (group C) were given a preterm formula (PF) until 4 months CA. Infants were examined at the outpatient clinics at term, and at 2, 4, 6, and 12 months CA, where parameters on growth, allergic diseases, possible feeding problems, blood-samples, and milk samples were obtained. Data on duration of exclusively breastfeeding and time of introduction to formula and/or complementary food were also recorded. Among the 478 infants 60% (n = 285) were exclusively breastfed, 35% (n = 167) were exclusively bottle-fed, and 5% (n=26) were both breast- and bottle-fed at discharge. Compared to mothers in lower social groups and mothers who smoked, mothers in higher social groups and \"non-smokers\" were significantly (p = 0.000 and p = 0.003 respectively) more often breastfeeding their very preterm infants at discharge. Single birth infants tended more often to be breastfed (p = 0.09). Infant age at discharge and duration of hospitalization did not influence breastfeeding at discharge. Increase in weight Z-score from birth to discharge was largest in the bottle-fed group compared to the breastfed group (p = 0.000), probably due to feeding practice the last week(s) of hospitalization. In the intervention study, 207 exclusively breastfed very preterm infants were randomized to group A (n = 102) and B (n = 105) respectively. The duration of breastfeeding was not influenced by fortification of mother's milk after hospital discharge. There was no significant difference on growth comparing group A and B at 12 months CA. Both boys and girls in group C achieved catch-up in weight and length earlier as compared to group A and B. Per protocol (PP) analysis showed that girls, but not boys, were longer and had a larger head circumference but were not heavier in group B (n = 51) compared to group A (n = 73) at 2 and 4 months CA (p&lt;0.05). Protein-concentration in mothers' milk declined significantly from 2 weeks (1.8 g/100 ml) to 6 weeks after birth (1.4 g/100 ml) and declined further to 1.2 g/100 ml 12 weeks after birth. The incidence and the prevalence at 12 months CA of recurrent wheezing was 39.2% and 32.7% respectively, while atopic dermatitis was 18.0% and 12.1% respectively. Predisposition to allergic disease increased the risk of developing atopic dermatitis (p = 0.04) (OR 2.6 (95% CI 1.0-6.4)), and the risk of developing recurrent wheezing (p = 0.02) (OR 2.7 (95% CI 1.2-6.3)). Boys had an increased risk of developing recurrent wheezing (p = 0.003) (OR 3.1 (95% CI 1.5-6.5)). In conclusion breastfeeding can successfully be established in very preterm infants. Fortification of human milk after hospital discharge while breastfeeding was possible without influencing the duration of breastfeeding. Fortification in the amount given in this study did, however, not affect growth significantly at 1 year of age. An increased amount of protein was correlated with increased BUN-values indicating a better growth potential. Fortification of mother's milk or preterm formula was not associated with an increased risk of developing allergic diseases. Future follow-up of this cohort investigating e.g. growth, allergic diseases, and neuropsychological development is planned at 6 years of age. The definition of optimal growth and nutrition of preterm infants is though still a question for debate and further investigations are needed." }, { "id": "pubmed23n0239_11021", "title": "Changing pattern of cow's milk intolerance.

FPIES in exclusively breastfed babies is a very rare clinical condition and only few cases have been reported in the medical literature. We describe two cases of FPIES in exclusively breastfed babies. The first one is a two-month-old infant with a brief history of vomit and diarrhea that presented to the Emergency Department in septic-like conditions.

An amino acid-based formula allowed a complete normalization of the symptoms. The second one is a three-month-old infant admitted for a 3 days history of persistent vomit and diarrhea. Blood tests showed a raised level of methemoglobin (7%). An esophagogastroduodenoscopy was performed and biopsies showed an eosinophilic infiltration of the duodenal mucosa.

The twins were delivered at 35 weeks gestation by Caesarian Section. Lily weighed 5 lbs 11 oz; Maggie was small-for-gestational age with a birth weight of 3 lbs 13 oz. Maggie required oxygen with nasal prongs for only a few hours after birth. She remained in the Neonatal Intensive Care Unit (NICU) with initial nasogastric tube feeding; she was advanced to bottle feeding prior to discharge. Both Maggie and Lily were slow to initiate and sustain formula feeding. They required over 1 hour to consume 2 ounces of formula and \"tire easily\". At 1 month of age, Maggie resisted feedings by crying and arching her back. By 5 months of age, both children cried at the sight of the bottle and tried to push it away. However, they never lost weight. Maggie was treated with intermittent naso-gastric tube feeding at 5-6 months of age in order to gain adequate weight. At 11 months of age, both girls continued to resist feeding, but their mother was able to \"get in\" 24 ounces each day of a 31-calorie/ounce formula \"with a lot of work\". Dad observed that his wife's entire day revolved around getting the twins to eat and that became a significant stress for her as well as on their relationship.

The age of the children at gluten introduction was similar, but the celiac children were significantly more often introduced by a gluten-containing follow-up formula, while the reference children more often started on a gluten-containing porridge. The results can be interpreted in two ways. First, it could be argued that breast milk per se protects against symptoms of celiac disease in childhood. It could, however, also be claimed that breast-feeding merely modulates the gluten introduction, causing a less abrupt introduction of gluten in the baby diet and thereby fewer overt symptoms of the disease." }, { "id": "pubmed23n0801_14682", "title": "[Breastfeeding: health benefits for child and mother].", "score": 0.009433962264150943, "content": "The prevalence of breastfeeding in France is one of the lowest in Europe: 65% of infants born in France in 2010 were breastfed when leaving the maternity ward. Exclusive breastfeeding allows normal growth until at least 6 months of age, and can be prolonged until the age of 2 years or more, provided that complementary feeding is started after 6 months. Breast milk contains hormones, growth factors, cytokines, immunocompetent cells, etc., and has many biological properties. The composition of breast milk is influenced by gestational and postnatal age, as well as by the moment of the feed. Breastfeeding is associated with slightly enhanced performance on tests of cognitive development. Exclusive breastfeeding for at least 3 months is associated with a lower incidence and severity of diarrhoea, otitis media and respiratory infection. Exclusive breastfeeding for at least 4 months is associated with a lower incidence of allergic disease (asthma, atopic dermatitis) during the first 2 to 3 years of life in at-risk infants (infants with at least one first-degree relative presenting with allergy). Breastfeeding is also associated with a lower incidence of obesity during childhood and adolescence, as well as with a lower blood pressure and cholesterolemia in adulthood. However, no beneficial effect of breastfeeding on cardiovascular morbidity and mortality has been shown. Maternal infection with hepatitis B and C virus is not a contraindication to breastfeeding, as opposed to HIV infection and galactosemia. A supplementation with vitamin D and K is necessary in the breastfed infant. Very few medications contraindicate breastfeeding. Premature babies can be breastfed and/or receive mother's milk and/or bank milk, provided they receive energy, protein and mineral supplements. Return to prepregnancy weight is earlier in breastfeeding mothers during the 6 months following delivery. Breastfeeding is also associated with a decreased risk of breast and ovarian cancer in the premenopausal period, and of osteoporosis in the postmenopausal period.

Infants born at three maternity hospitals were followed from birth: 279 infants with high atopic risk (intervention group) were compared with 80 infants with similar atopic risk but no intervention (non-intervention group). The intervention programme included dietary measures (exclusive and prolonged milk feeding diet followed by a hypoantigenic weaning diet) and environmental measures (avoidance of parental smoking in the presence of the babies, day care &gt; 2 years of life). Mothers in this group who had insufficient breast milk were randomly assigned to one of two coded formulas: either a hydrolysed milk formula (Nidina HA, Nestlé) or a conventional adapted formula (Nan, Nestlé). Other environmental measures remained the same as for the breastfeeding mothers. The non-intervention group were either breastfed or received the usual Italian milk feeding and weaning diet, without environmental advice. The main outcome measures were anthropometric measurements and allergic disease manifestations. Normal anthropometric data were observed both in the intervention group and in the non-intervention group. The incidence of allergic manifestations was much lower in the intervention group than in the non-intervention group at 1 year (11.5 versus 54.4%, respectively) and at 2 years (14.9 versus 65.6%) and 3 years (20.6 versus 74.1%). Atopic dermatitis and recurrent wheezing were found in both the intervention group and the non-intervention group from birth up to the second year of life, while urticaria and gastrointestinal disorders were only present in the non-intervention group in the first year of life. Conjunctivitis and rhinitis were present after the second year in both the intervention group and the non-intervention group. Relapse of the same allergic symptom was less in the intervention group (13.0%) than in the non-intervention group (36.9%). In comparison to the non-intervention group, there were fewer intervention group cases with two or more different allergic symptoms (8.7 versus 32.6%), and they were more likely to avoid steroid treatment (0 versus 10.8%) and hospital admission (0 versus 6.5%). Babies in the non-intervention group fed with adapted formula were more likely to develop allergies than breastfed babies in the same group. In the intervention group the breastfed infants had the lowest incidence of allergic symptoms, followed by the infants fed the hydrolysed formula (ns). Infants in the intervention group fed the adapted formula had significantly more allergies than the breastfed and hydrolysed milk fed infants, although less than their counterparts in the non-intervention group. Of the affected subjects in the intervention group, 80.4% were RAST and/or Prick positive to food or inhalant allergens.

The incidence of postoperative complications is higher when the cervical region has been irradiated with a dose equal or higher to 5,500 tumor rads or when the larynx, pharynx and/or buccal cavity have been entered." }, { "id": "pubmed23n1157_9975", "title": "A Unique Presentation of Ectopic Thyroid Tissue: Case Report and Management Principles.", "score": 0.009708737864077669, "content": "Ectopic thyroid is a rare clinical presentation to encounter in day-to-day clinical practice. It occurs due to developmental defects in the early stages of the thyroid gland embryogenesis during its descent from the floor of the primitive foregut to its final pre-tracheal position. It is usually present along the extent of the thyroglossal duct as well as in distant locations such as sub-diaphragmatic or mediastinal spaces. The diverse clinical presentation of this rare entity often causes a diagnostic dilemma. A thyroid scintigraphy scan is pivotal in the diagnosis of ectopy, but ultrasonography is done more frequently. Surgical management is preferred for symptomatic cases, followed by radioactive iodine ablation and levothyroxine supportive therapy for refractory cases. We present a case of a 62-year-old female patient who presented with pain and swelling of the right submandibular region. On ultrasonography, a 5*4 cm firm mobile swelling of the right submandibular region was found, suggestive of right submandibular sialadenitis. Fine needle aspiration cytology (FNAC) was subsequently done, and it showed features of basaloid neoplasm like pleomorphic adenoma, and as the thyroid tissue was in an ectopic location, it must have been misdiagnosed. The patient was then taken up for right submandibular sialoadenectomy, and the histopathological examination of the operative specimen showed nodular colloidal goiter and mild chronic sialadenitis. Ectopic thyroid can present at various anatomical locations and thereby has varied clinical presentations which makes it a diagnostic dilemma for clinicians. The usual radiological investigations done include USG and CT scan, whereas thyroid scintigraphy is more precise in reaching the diagnosis of ectopic thyroid. The confirmatory diagnostic method is the histopathological examination of the excised specimen. Most cases of ectopic thyroid are asymptomatic and require regular follow-up. Symptomatic cases are managed by surgical excision followed by periodic monitoring and adequate thyroxine replacement." }, { "id": "pubmed23n0370_9856", "title": "The value of elective neck dissection in treatment of cancer of the tongue.", "score": 0.009708737864077669, "content": "The \"adequate\" therapy of tongue cancer has not yet been determined. The authors report their experience with 58 N(0) patients to elucidate the role of elective neck dissection in surgical treatment of cancer of the tongue.

TNM staging, intraoperative N staging, pathologically confirmed cervical lymph node metastases and their levels, and clinical outcomes (local and regional recurrences) were recorded. The sensitivity and specificity of intraoperative staging was determined. Fifty-four percent (31/58) of the patients presented as T(1), and 26% (15/58) as T(2). The overall occult metastasis rate was 29.3% (17/58). The occult metastasis rate for T(1) and T(2) lesions was 19.4% (6/31) and 26.7% (4/15), respectively. The sensitivity of intraoperative staging was 76.5%, and the specificity was 51.2%. The rate of occult metastasis to the neck is too high in all tongue cancer cases to take the risk of regional recurrence, and the surgeon can not solely depend on neck palpation for determination of neck metastasis.

The main causative factors include dental infections (dental caries with atypical periodontitis, pericoronitis, and dental procedures). Other predisposing conditions include poor dental hygiene, dental caries, malnutrition, diabetes mellitus, AIDS, and various other immunocompromised states. It presents as an acute onset and spreads very rapidly causing bilateral diffuse neck swelling, edema of floor of mouth, pain, fever, trismus, foul-smelling pus discharge, difficulty in swallowing, airway edema, and tongue displacement creating a compromised airway with stridor. So it requires early diagnosis and aggressive management. Material and methods Clinical data of all patients with clinical diagnosis of Ludwig's angina managed at the Department of Otorhinolaryngology-Head and Neck Surgery, Sir Takhatsinhji (T) General Hospital and Government Medical College, Bhavnagar, India, from 2015 to 2019 were analyzed retrospectively in this study. Result Over the review period, 30 cases were diagnosed as Ludwig's angina, out of which 12 (40%) were males and 18 (60%) were females; male to female ratio was 1:1.5. The age of the patients ranged from six months to 64 years, with a mean age of 38.86 years. Fever, neck swelling, and neck pain were present in all patients. In 16 patients, incision and drainage were done under general anesthesia while the rest five patients required only local anesthesia. In six patients (20%), for maintenance of airway, tracheostomy was required. The most common complication was necrotizing fasciitis and death followed by septicemia. Mortality was observed in three patients (10%) in this study. Conclusion Despite improved outcomes compare to pre-antibiotic era, Ludwig's angina still remains a potentially life-threatening disease in ENT at present. Dental caries, uncontrolled diabetes mellitus, and malnutrition are commonly associated conditions. With early diagnosis, close airway observation, aggressive intravenous antibiotic treatment, and timely surgical intervention, morbidity, and mortality can be reduced." }, { "id": "pubmed23n0278_5688", "title": "Squamous carcinoma presenting as an enlarged cervical lymph node.", "score": 0.009523809523809525, "content": "Patients presenting with an enlarged cervical lymph node containing squamous cell carcinoma are a difficult problem for head and neck surgeons. In most cases, the primary site lies in the head and neck region. The advent of fine-needle aspiration cytologic study means that this group of patients can be accurately identified in the clinic and investigated accordingly. The current report studies the records of 267 such patients presenting to the Head and Neck Unit at The University of Liverpool over a 29-year period. The 5-year survival rate for all patients presenting with a cervical lymph node metastasis was 27%. The 5-year survival rate for patients with a detected primary in the head and neck was 31% and the primary site was identified during the patient's life time in all but 36 patients (13%). In 53% of patients, the primary site was discovered during routine clinical examination, and in a further 16% it was discovered at panendoscopy. Most diagnostic tests proved relatively unhelpful but 10 patients in our series had the primary site discovered by radiograph and 9 of these had carcinoma of the lung. In the current study when the primary site was discovered it was in the head and neck region in 74% of patients. Primary sites other than head and neck occurred in 11% of the patients and no 5-year survivors existed. Multivariate analysis suggested that open biopsy of the lymph node metastasis appeared to have an adverse effect on survival as did advanced age and advanced N stage. The late diagnosis of the primary site, if it proved to be in the head and neck region, on the other hand, had a positive association with survival. Patients presenting with a lymph node metastasis in the head and neck region from an unknown primary have a prognosis identical to that of other patients with head and neck squamous carcinoma with neck node metastases. The prognosis for patients in whom the primary site is never discovered or in whom the primary site is not head and neck, however, is disastrous. If the primary tumor proves to be in the head and neck region, treatment is worthwhile since almost a third of patients are cured of their disease. When the primary carcinoma is not in the head and neck region, treatment must be considered palliative." }, { "id": "pubmed23n1094_11212", "title": "Fine needle aspiration in COVID-19 vaccine-associated lymphadenopathy.", "score": 0.009433962264150943, "content": "With ongoing intensive vaccination programme against COVID-19, numerous cases of adverse reactions occur, some of which represent rare events.

As patients at risk of a severe course of COVID-19, indicated by their medical history such as a previous diagnosis of malignancy, receive priority vaccination, newly palpable lymph nodes raise concerns of disease progression. In this case series, we report on five patients who presented with enlarged lymph nodes after COVID-19 vaccination. Sonography guided fine needle aspiration (FNA) was performed in five patients presenting with PET-positive and/or enlarged lymph nodes after COVID-19 vaccination with either the Pfizer-BioNTech or Moderna vaccine. COVID-19 vaccination had been carried out in all cases, with an interval of between 3 and 33 days prior to FNA. Three of five patients had a history of neoplasms. The vaccine was administered into the deltoid muscle, with subsequent enlargement of either the cervical, supra-, infra- or retroclavicular, or axillary lymph nodes, in four out of five cases ipsilaterally. In all cases, cytology and additional analyses showed a reactive lymphadenopathy without any sign of malignancy. Evidence of newly enlarged lymph nodes after recent COVID-19 vaccination should be considered reactive in the first instance, occurring owing to stimulation of the immune system. A clinical follow-up according to the patient&amp;rsquo;s risk profile without further diagnostic measures is justified. In the case of preexisting unilateral cancer, vaccination should be given contralaterally whenever possible. Persistently enlarged lymph nodes should be re-evaluated (2 to) 6 weeks after the second dose, with additional diagnostic tests tailored to the clinical context. Fine needle aspiration is a well established, safe, rapid and cost-effective method to investigate an underlying malignancy, especially metastasis.

The main area of debate in case of diagnosis lies with the fact that whether we should rely on ultrasound, as a diagnostic modality for diagnosing micrometastases in the neck in head and neck malignancy patients? The second controversial issue is the management of N0 neck, whether to be radical or conservative? This study was conducted on 70 diagnosed patients of head and neck carcinoma who were planned for resection of the primary. An appropriate neck dissection was performed in all the patients, and their clinical, ultrasonography, and postoperative histopathological neck findings were correlated. In our center, the most common site of the primary tumor was oral cavity with most involving buccal mucosa. As expected, T4 lesions were commonly associated with nodal metastasis (71%). The sensitivity of clinical examination and ultrasound was 80% and 93.3%, respectively, and specificity of clinical examination and ultrasound was 57% and 27.2%, respectively. Histopathologically positive but clinically nonpalpable metastases in the study group were more frequent in levels Ib, II, and III, respectively. We concluded that ultrasonography being a low cost and a highly sensitive investigation can act in tandem with clinical examination for diagnosing the neck for metastases preoperatively in head and neck malignancy patients. However, due to its low specificity, we cannot completely rely on it, hence doing a neck dissection in selective form, will definitely improve the clinical course of the disease in N0 necks." }, { "id": "pubmed23n0285_18756", "title": "Unusual small bone metastases from epithelial malignancies: diagnosis by fine-needle aspiration cytology with histologic confirmation.", "score": 0.009345794392523364, "content": "Although epithelial malignancies can have bone metastases, involvement of small bones is exceedingly rare, representing either first manifestation of an occult carcinoma or late disseminated disease.

Major changes (affecting treatment or prognosis) occur in 5 to 7% of surgical pathology cases. The thyroid is consistently identified as a site that is particularly prone to diagnostic discrepancies; and no specific head and neck sites are immune to diagnostic error. Limited studies addressing the site-specific impact of second opinion pathology implicate the head and neck as a high-risk area that is prone to major changes in diagnoses.

In these cases, a systematic tonsillectomy in the absence of suspicious lesions is discussed since up to 25% of primary tumours can be detected in this site. Thoracic, and abdominal primaries (especially from lung, oesophagus, stomach, ovary or pancreas) should be sought in the case of adenocarcinoma and involvement of the lower neck. Positron emission tomography with fluoro-2-deoxy-D-glucose allows detection of primary tumour in about 25% of cases, but this procedure is still considered investigational.

In 10 (45.5%), the lymphangioma involved the neck, 5 of them presented with sudden neck swelling as a result of hemorrhage into a lymphangioma, which caused diagnostic confusion. One patient had extensive lymphangioma involving the floor of the mouth, tongue, and left parotid gland. The remaining 11 patients had lymphangioma involving the parotid gland in 2, floor of the mouth in 3, and one each in the abdominal wall, above the right knee, mediastinum, breast, scrotum, and mesentery. All were treated surgically except 3 who were treated with intralesional bleomycin and showed complete disappearance of their lesions. There was recurrence in the child with mediastinal lymphangioma and a small recurrence in the child with bilateral lesions in the floor of the mouth. Lymphangiomas are relatively rare, involving mainly the head and neck, but they can be rarely seen at other sites. An important observation is the sudden appearance of cervical lymphangioma as a result of hemorrhage, which should be kept in mind. Our experience in the treatment of lymphangiomas using bleomycin is limited to draw any conclusions. We therefore considered surgery as treatment of choice for lymphangiomas. However, sclerotherapy can be used when there is a risk of damaging surrounding structures, and also to obviate the poor cosmetic results." }, { "id": "pubmed23n0419_4302", "title": "Fine needle aspiration cytology of head and neck masses.

FNA from 225 patients with head and neck masses were reviewed. The results were analyzed, according to anatomic location, into 3 groups: inflammatory, congenital and neoplastic. FNA diagnoses were retrospectively correlated with available histologic findings or with the outcome of treatment. Accuracy, sensitivity, specificity, positive predictive value and negative predictive value in the diagnosis were computed. The numbers of lymph node biopsies performed before and after introduction of the procedure were compared. The most common diagnoses were reactive/nonspecific lymphadenitis and tuberculous (TB) lymphadenitis (33% and 21%, respectively). Sensitivity and negative predictive value for TB were 97% and 93%, respectively. The next most common masses were malignant neoplasms, cysts, benign neoplasms and sialadenitis, in 13%, 11%, 9% and 5%, respectively. Carcinomas metastatic to the lymph node were the most common type of cancer, followed by lymphoma and salivary gland carcinoma. The primary site of metastatic carcinomas were nasopharynx (44%) and thyroid (22%). The sensitivity and negative predictive values for the diagnosis of cancer were 95% and 96%, respectively, but reached 100% when lymphoma was excluded. The introduction of FNA reduced the number of lymph node biopsies performed in this hospital by 90%. FNA of head and neck masses proved to be a very useful diagnostic tool in separating inflammatory lesions (no surgical excision required) from cystic and neoplastic lesions. It enhanced surgical planning for malignant diseases, allowing rapid referral of lymphomas and cancer cases to tertiary care centers for management. FNA is simple, cost effective and suitable for developing countries and small, secondary care hospitals with limited resources.

We analysed the experience of the Peter MacCallum Cancer Institute to assess the risk of withholding mucosal irradiation in relation to the diagnostic algorithm used to exclude a primary lesion at the time of initial presentation. Between 1983 and 1992, 69 patients were seen with metastatic squamous or undifferentiated carcinoma in cervical nodes from an unknown primary site. Neck nodal stage was NX or N1 13%; N2 52%; N3 35%. Nodal disease was bilateral in 12% of patients. Investigations included examination under anaesthesia, with or without random biopsies, in 84%, and CT scanning of the head and neck in 55%. Treatment was by surgery alone in four patients, by radiotherapy alone in 23, and by combined modalities in 40. Two patients received no treatment. Seventeen were treated with palliative intent. The radiotherapy fields provided comprehensive coverage of the pharynx in only eight patients and partial coverage in five. The estimated overall 5-year survival was 36%. Eleven primary tumours were detected between 7 months and 7 years after the initial treatment, of which nine were in head and neck sites. This yielded an estimated incidence of 30% at 10 years, which is similar to the risk of the development of a second primary after the successful treatment of a known head and neck cancer. Only three patients (none of whom had a CT scan as part of their initial evaluation) manifested a primary in an unirradiated pharyngeal site within 2 years of treatment. As the accuracy of imaging improves, the risk of missing an occult primary lesion will decrease further. We conclude that the use of standardized diagnostic investigations incorporating modern imaging substantially eliminates the indication for comprehensive elective mucosal irradiation with its consequent morbidity. The overriding priority in patients who present with advanced neck disease is to secure regional control." }, { "id": "pubmed23n1064_24613", "title": "Diagnosis and management of Ludwig's angina: An evidence-based review.", "score": 0.008771929824561403, "content": "Ludwig's angina is a potentially deadly condition that must not be missed in the emergency department (ED). The purpose of this narrative review article is to provide a summary of the epidemiology, pathophysiology, diagnosis, and management of Ludwig's angina with a focus on emergency clinicians. Ludwig's angina is a rapidly spreading infection that involves the floor of the mouth. It occurs more commonly in those with poor dentition or immunosuppression. Patients may have a woody or indurated floor of the mouth with submandibular swelling. Trismus is a late finding. Computed tomography of the neck soft tissue with contrast is preferred if the patient is able to safely leave the ED and can tolerate lying supine. Point-of-care ultrasound can be a useful adjunct, particularly in those who cannot tolerate lying supine. Due to the threat of rapid airway compromise, emergent consultation to anesthesia and otolaryngology, if available, may be helpful if a definitive airway is required. The first line approach for airway intervention in the ED is flexible intubating endoscopy with preparation for a surgical airway. Broad spectrum antibiotics and surgical source control are keys in treating the infection. These patients should then be admitted to the intensive care unit for close airway observation. Ludwig's angina is a life-threatening condition that all emergency clinicians need to consider.

Nevertheless, to date, the total number of reported cases of each of these conditions is estimated to be in double digits. Both manifest as a constellation of features like craniofacial dysmorphism, hypotonia, intellectual impairment and global developmental delay. Characteristic facies include protruded forehead, hypertelorism, epicanthic folds, down slanting palpebral fissures, flat nasal bridge, long philtrum, thin upper lip, carp-shaped mouth, retro-micrognathia and low set ears. Besides, trisomy 10p is strikingly associated with clinodactyly and camptodactyly which aids in clinical diagnosis, apart from other musculoskeletal deformities like hip dysplasia and pes planus. Intersex conditions have been found to commonly co-exist. As other systems also display involvement frequently, trisomy 10p is a discernible multiple congenital anomalies/mental retardation (MCA/MR) syndrome. On the other hand, with terminal 14q deletion, increased risk of certain types of cancer was predicted as specific tumor suppressor genes are lost in the deletion and thus, screening was recommended. Genetic workup using techniques like fluorescence in situ hybridization (FISH), spectral karyotyping (SKY) and chromosomal microarray-based comparative genomic hybridization (CGH) was found to be helpful in diagnosis of trisomy 10p and 14q deletion. Prenatal diagnosis of these conditions has been well documented too. Intrauterine growth retardation has been observed to be related to trisomy 10p. There is a paucity of literature on the management of children diagnosed with trisomy 10p or with terminal 14q deletion. Although management of a child diagnosed with concomitant occurrence of trisomy 10p and terminal 14q deletion by a multidisciplinary approach emphasizing physiotherapeutic intervention has shown remarkable improvement in motor skills, the care of children diagnosed with these genetic aberrations needs further investigation. Documentation of more such cases will help to expand phenotypic spectrum for early identification and to delineate natural history for a life span approach. Early identification and intervention facilitate tapping of the maximum neuroplastic potential for better neurodevelopmental outcomes.

The condition is the second most common autosomal trisomy syndrome after trisomy 21. The live born prevalence is estimated as 1/6,000-1/8,000, but the overall prevalence is higher (1/2500-1/2600) due to the high frequency of fetal loss and pregnancy termination after prenatal diagnosis. The prevalence of trisomy 18 rises with the increasing maternal age. The recurrence risk for a family with a child with full trisomy 18 is about 1%. Currently most cases of trisomy 18 are prenatally diagnosed, based on screening by maternal age, maternal serum marker screening, or detection of sonographic abnormalities (e.g., increased nuchal translucency thickness, growth retardation, choroid plexus cyst, overlapping of fingers, and congenital heart defects ). The recognizable syndrome pattern consists of major and minor anomalies, prenatal and postnatal growth deficiency, an increased risk of neonatal and infant mortality, and marked psychomotor and cognitive disability. Typical minor anomalies include characteristic craniofacial features, clenched fist with overriding fingers, small fingernails, underdeveloped thumbs, and short sternum. The presence of major malformations is common, and the most frequent are heart and kidney anomalies. Feeding problems occur consistently and may require enteral nutrition. Despite the well known infant mortality, approximately 50% of babies with trisomy 18 live longer than 1 week and about 5-10% of children beyond the first year. The major causes of death include central apnea, cardiac failure due to cardiac malformations, respiratory insufficiency due to hypoventilation, aspiration, or upper airway obstruction and, likely, the combination of these and other factors (including decisions regarding aggressive care). Upper airway obstruction is likely more common than previously realized and should be investigated when full care is opted by the family and medical team. The complexity and the severity of the clinical presentation at birth and the high neonatal and infant mortality make the perinatal and neonatal management of babies with trisomy 18 particularly challenging, controversial, and unique among multiple congenital anomaly syndromes.

A potential candidate gene causative for limb malformation in our proband could be FGFR4, which maps relatively in the closest position to the chromosomal breakage site (about 1.3 Mb) from all known 5q duplications.

The records of 203 children aged 0-15 years diagnosed with acute lymphoblastic leukemia from 2006 to 2016 were revisited. The results of the blood workup showed a median white blood cell count of 7120 × 10<sup9</sup/L (range: 450-600,000 × 10<sup9</sup/L), and a median hemoglobin concentration of 7.5 g/dL (range: 2.4-15.3 g/dL), whereas the median platelet count was 47,400 × 10<sup9</sup/L (range: 4000-544,000 × 10<sup9</sup/L). Leukocytosis and leukopenia were present in 36.6% and 36.1% of cases, respectively; anemia was diagnosed in 82.9% children. The order of frequency for major clinical symptoms was fatigue 62%, fever 60%, bone and joint pain 39%, hyporexia 33% and weight loss 21%, while main physical findings were hepatomegaly 78%, splenomegaly 63%, lymphadenopathy 57%, pallor 48%, and purpura 30%.

The clinical characteristics, physical examination, laboratory tests, gene tests, and treatment process were analyzed and related literature was reviewed. The patient was a 16-month- old boy.Since the first month of life, he started to have repeatedly fever, diarrhea, shortness of breath, lymphadenopathy, hepatosplenomegaly, anemia (HGBmin 50 g/L) and thrombocytopenia (min 35 × 10⁹/L) . But multiple exams showed a normal peripheral blood leukocyte count, hypergammaglobulinemia (IgG 19 800 mg/L, IgA 1 710 mg/L, IgM 2 590 mg/L) and significantly increased serum vitamin B12.

He was treated with prednisone 15 mg once daily and immunomodulator 150 mg three times a day, while in maintaining period with normal levels of hemoglobin and platelet, the dose of prednisone was reduced gradually. Till now, the patient has been treated and observed for 8 months. We retrieved the reports of ALPS in the databases at home and abroad published in recent 10 years, more than 400 cases reported from foreign countries, but there were only 5 domestic cases. Among those, 4 had onset in infancy and 1 at 6-years of age. All the cases presented servere lymphadenopathy and hepatosplenomegaly with anemia (4 of them with hemolytic anemia) and thrombocytopenia. Three cases had a history of frequent infection, one of them had glomerulonephritis.

All patients were treated with corticosteroid, 2 of them were added with mycophenolate mofetil. The therapy presented effective result in early 1-3 months, but no long-term follow-up reports were available. ALPS is a disorder of disrupted lymphocyte homeostasis caused by defective Fas-mediated apoptosis, and it is one of the primary immunodeficiency diseases. The onset of the disease occurs during infancy mainly. Clinical lymphoid hyperplasia and autoimmune phenomena are outstanding signs, which can be associated with frequent infections and allergies. The level of serum vitamin B12 &gt; 1.5 pg/L and the count of CD3⁺ CD4⁻ CD8⁻ T cell show important significance.

He was treated for 20 years with testosterone IM once monthly, which he stopped a year before the current hospitalization for unclear reasons. The patient reported no congenital lymphedema. Physical examination revealed two deep skin ulcers (Figure 1) on the right leg measuring 10 cm in diameter with raised irregular inflammatory borders and a boggy, necrotic base discharging a purulent hemorrhagic exudate. Bilateral leg pitting edema and right lymphangitis with lymphadenitis were noted. He had low head hair implantment, sparse hair on the body and head, hyperpigmentation on both legs, onychodystrophia of the toenails (mainly the large toe and less prominent on the other toes), which was atrophic lichen-planus-like in appearance and needed no trimming (Figure 2), normal hand nails, oral thrush, and angular cheilitis.

In the Pel-Ebstein pattern, fever lasting 3–10 days is followed by afebrile periods of 3–10 days; this pattern can be classic for Hodgkin’s disease and other lymphomas. In cyclic neutropenia, fevers occur every 21 days and accompany the neutropenia. There is no periodicity of fever in patients with familial Mediterranean fever.

Due to low back pain, an orthopedist had indicated i.v. zoledronic acid, 5 mg/year for 3 years (2006-2008). She received occasional supplements of ergocalciferol. In 2009, she suffered a fall and sustained a subtrochanteric fracture of the left femur. She was operated on and recovered uneventfully. In 2012, she consulted a dentist due to loose teeth. She underwent the removal of a molar and was given a denture. She had discomfort when using the prosthesis, and developed an ulceration in the gum of the mandible, which exposed the bone and did not heal for 2 months. After radiologic studies, the diagnosis was osteonecrosis of the jaw. She improved after surgical debridement and local and systemic antibiotics.

She underwent exploratory laparotomy with tumor debulking surgery at that time. Shortly thereafter, she was readmitted to the same hospital with evidence of partial small bowel obstruction and treated conservatively with bowel rest, nasogastric (NG) tube placement, and intravenous (IV) fluid administration. Eventually the NG tube was removed, and she was discharged home. The following day, she received cycle one of palliative chemotherapy with cisplatin and gemcitabine at her local outpatient oncology clinic. She experienced persistent nausea and intermittent vomiting throughout the night and presented to our local community hospital for evaluation. At the time of admission, she was passing minimal flatus and had passed only a small bowel movement that morning. She had experienced nausea, vomiting, and poor oral intake for over a week. Other presenting symptoms included mild to moderate abdominal pain involving the upper abdomen. Upon evaluation, abdominal x-ray revealed dilated loops of small bowel, consistent with partial small bowel obstruction. An NG tube was placed, and the patient's symptoms were initially improved with bowel rest. Her medical history was significant for pulmonary embolism detected at the time of her adenocarcinoma diagnosis, and she was on oral anticoagulation and home oxygen. She also had a history of depression and total abdominal hysterectomy/bilateral salpingo-oophorectomy (TAH/BSO) due to fibroids. Her social history revealed she was an office worker and married with two sons, ages 18 and 24. The 18-year-old son lived at home with the patient and her husband. The patient was eagerly awaiting the birth of a granddaughter, due in a few weeks' time. Her mother and father were also present daily during her hospitalization and were a major source of support for her and her family. At the time of hospital admission, a surgical team consultation concluded she was not a candidate for palliative surgery due to extensive disease burden. She was seen in consultation by medical oncology, who recommended resuming chemotherapy once the acute partial small- bowel obstruction resolved. <bPalliative Care Consult</b A palliative care consultation was requested to assist with symptom management, including pain and nausea relief. At the time of consultation, the patient appeared in mild distress due to abdominal pain and distention. Vital signs were stable. Physical exam was significant for absent bowel sounds and a mildly distended but nontender abdomen. The NG tube was in place, draining bilious gastric fluid. She had mild nonpitting edema involving the bilateral lower extremities. Discussion with the patient revealed values consistent with improving symptoms and extending life expectancy as long as possible. The patient expressed wishes for \"aggressive treatment,\" which she defined as continuation of chemotherapy and full resuscitation. The palliative care team discussed symptom management options with the patient. Nonsurgical management of partial bowel obstruction was continued, including bowel rest, NG tube decompression, and IV fluids. Pain was controlled initially with IV morphine as needed. After symptom improvement and evidence of bowel function recovery, the NG tube was removed. However, after a short time, she required NG tube replacement due to recurrent nausea and vomiting. Discussion was initiated with the patient, who opted for placement of a venting gastrostomy tube (G-tube) and total parenteral nutrition (TPN), with the goal of symptom relief and administration of nutrition, which would allow for continuation of chemotherapy. During placement of the venting G-tube, the gastroenterology (GI) team noted extensive tumor involving the stomach, which made placement of the tube difficult. Additionally, anticoagulation was held during G-tube placement, and postoperatively, the patient experienced acute, right-sided chest pain and shortness of breath. Computed tomography (CT) scan with pulmonary embolus (PE) protocol revealed a new PE, and anticoagulation was changed to enoxaparin. Shortly thereafter, she became febrile and developed leukocytosis. Blood cultures revealed coagulase-negative staphylococcus from a Port-a-Cath source. She was treated with appropriate antibiotic therapy; however, follow-up blood cultures revealed persistent coagulase-negative staphylococcus bacteremia. Her indwelling Port-a-Cath was removed. After appropriate antibiotic therapy, a peripherally inserted central catheter line was inserted and TPN restarted. <bReinstituting Palliative Chemotherapy</b Palliative care discussion with the patient confirmed her desire to reinstitute palliative chemotherapy, with the goal of restoring bowel function and returning home. Chemotherapy was resumed on day 15, despite concerns and even objections from several nursing staff members. The patient experienced treatment side effects, including prolonged thrombocytopenia. A platelet function antibody returned positive, consistent with heparin-induced thrombocytopenia. Enoxaparin was discontinued, and fondaparinux (Arixtra) was initiated. Platelet count recovered shortly thereafter. The patient required intense symptom management due to intractable abdominal pain and nausea and vomiting despite adequate venting G-tube decompression. Medical management was maximized with antiemetics, antisecretory agents, steroids, and antipsychotic agents, and symptoms eventually improved after cycle 2 of chemotherapy. Thereafter, the patient was discharged home. At the time of discharge, her symptoms were well controlled on minimal pain medications. She was still experiencing intermittent nausea but was passing flatus. By reducing the tumor burden, chemotherapy significantly improved her quality of life. She spent a total of 7 weeks in the hospital. During that time, she received two cycles of chemotherapy plus best supportive care and symptom management. Despite intermittent nausea and vomiting, administration of palliative chemotherapy allowed this patient to achieve her primary goals, which included returning home to her family and regaining some bowel function. Over the next several months, she received several more cycles of outpatient palliative chemotherapy. She experienced mild to moderate nausea and intermittent vomiting despite G-tube venting. Eventually, her disease progressed, and the patient chose to forgo any further intervention or chemotherapy. She was enrolled in hospice care and died comfortably at home surrounded by her family." }, { "id": "wiki20220301en137_42614", "title": "Ruth Lyons (broadcaster)", "score": 0.009433962264150943, "content": "Later years, retirement and death The mid-1960s were a time of illness and sorrow for Lyons and her family.

Within 10 hours of hospitalization, her symptoms deteriorated further with rebound tenderness during the examination, tachycardia, and a drop of 12 units in her hematocrit value. An emergency laparotomy was performed. Two mesenteric cysts and a 60 cm necrotic part of her intestine were revealed intraoperatively. In the postoperative period, she complained of acute abdominal pain, tachycardia, and dyspnea. Computed tomography imaging revealed mesenteric vein thrombosis and pulmonary thromboembolism. She was treated with low molecular weight heparin and she was discharged on the 11th postoperative day. To the best of our knowledge, this is the first report in the literature of a simultaneous mesenteric cyst and mesenteric vein thrombosis in pregnancy.

It is therefore justifiable to search for them systematically by breast examination of all patients over 30. Large-scale mass screening campains in the USA, with clinical and mammographic examination of tens of thousands of women, have proven that it is possible to detect more \"early\" cancers and reduce general mortality in the groups studied. The number of cancers thus detected is nevertheless so small that it does not justify the investment of so much labour and money in this kind of campaign. Systematic breast examination at regular intervals (6 months to 1 year) with regular mammographies should be confined to patients in the high risk groups: women who have already undergone surgery for cancer of one breast, and patients with a marked family history of breast cancer. For the rest of the female population, the solution seems obvious: every physician should get into the habit of performing regular clinical examination of the breasts. Most gynecologists are already doing so, but they only examine a small part of the population. The most important role in the detection of breast cancer falls to the internists and the general practitioners: they should assume responsibility for all their patients' breasts, in the same manner as they do for heart and lung examinations. They will then request additional examinations (mammography, thermography) as soon as clinical examination reveals a pathological finding. The results of GILBERTSEN [5] confirm that clinical examination remains the most valuable and least expensive method for breast cancer detection." }, { "id": "pubmed23n0788_11342", "title": "Sickle cell disease with osteogenesis imperfecta.", "score": 0.009259259259259259, "content": "A 16 yr old female presented with generalized weakness and easy fatigability since 2 months.

KS was in her usual state of good health when she noticed a left breast mass in the inferior reconstructed breast in June 2017. She presented to the nurse practitioner (NP) in the surgical oncology clinic for evaluation. At that time, she was 17 weeks pregnant and being seen in the same facility for high-risk obstetrics and gynecology care. KS had no other concerning symptoms for recurrent cancer, and her pregnancy had been progressing smoothly.The surgical oncology NP noted a 1-cm firm superficial mass in the breast at 6 o'clock. She had no other bilateral breast findings or adenopathy. Upon review of systems, she denied new persistent headache, shortness of breath, abdominal pain, weight loss, night sweats, or fatigue.Due to her pregnancy and the superficial presentation of the breast mass, a left breast ultrasound was ordered. It revealed an 8-mm irregular hypoechoic mass 7 cm from the nipple at the 6 o'clock position in the reconstructed breast.A diagnostic workup ensued with a left breast ultrasound-guided core needle biopsy. KS was given a diagnosis of clinical stage T1b, N0, grade 2 invasive micropapillary carcinoma: ER positive (Allred 6), PR positive (Allred 8), HER2/<ineu</i, immunohistochemistry 3+, and fluorescence in situ hybridization amplified.After discussion of this recurrent cancer diagnosis, her team opted for a bilateral diagnostic mammogram (with abdominal shielding) and bilateral axillary and breast ultrasound to evaluate the contralateral breast and lymph nodes. There was no adenopathy, a small amount of accessory breast tissue in the right axillary tail region, and a biopsy clip was noted in the left inferior breast at 6 o'clock. The new cancer was not seen on mammogram, likely due to the proximity to the implant." }, { "id": "pubmed23n1130_20912", "title": "A 20-Year-Old Woman With Thoracic Pain and Progressive Dyspnea on Exertion.", "score": 0.009174311926605505, "content": "A 20-year-old woman presented with dry cough, right-sided thoracic pain, and gradually progressive dyspnea on exertion.

The six dissected lymph nodes were negative for malignancy. Her surgical history was otherwise unremarkable. Her medical history was positive for hypercholesterolemia and depression. Pertinent family history included breast cancer in both her mother and her sister. Given the patient's age, tumor size, lack of nodal involvement, and clear surgical margins, she met recommended MammoSite criteria, and she underwent accelerated partial breast radiation. She subsequently received 340 cGy of radiation twice a day for a total dose of 3400 cGy in 10 administrations in February 2005. Accelerated partial breast radiation treatment was completed in February 2005, and she received subsequent routine care.

Early recognition of symptoms and immediate descent are important for successful treatment. Despite early signs and symptoms of high altitude illness, many trekkers tend to push themselves to the maximum limit. Some of them, such as the case reported here, choose to ascend on horse-back which is extremely dangerous and can be fatal. A 55 years of age Indian ethnic South African lady was emergency air-lifted from 4410 m altitude in the Nepal Himalayas to Kathamandu (1300 m) with a suspected case of high altitude pulmonary edema. She had continued ascending despite experiencing mild altitude symptoms at Namche (3440 m), and these symptoms worsened considerably at Tengboche (3860 m). At the very start of her trek, just after Lukla (2800 m), she suffered from sore throat, and had consequently begun a course of antibiotics (azithromycin) for a suspected throat infection. She had planned to continue ascending on horse back to complete the trek, however her condition deteriorated further and she had to be medically evacuated.On admission to the clinic her axillary temperature was 99.4 F, blood pressure 120/60 mmHg, pulse rate 72/min, respiratory rate of 25 breaths/min, and pulse oximeter showed saturation of 90% on room air at rest. Right sided crackles on the axillary and posterior region were heard on chest auscultation. Heel to toe test showed no signs of ataxia. The chest radiograph showed patchy infiltrates on the right side. An echocardiogram was done which revealed a high pulmonary artery pressure of 50 mm of Hg. She was diagnosed as resolving high altitude pulmornay edema. She was treated with bed rest, supplemental oxygen and sustained release nifedipine 20 mg (orally) twice a day. On the third day her crackles had cleared significantly and repeat chest radiograph as shown showed remarkable improvement. She felt much better. A repeat echocardiogram revealed a normal pulmonary artery pressure. The case report highlights numerous points:1) Many high altitude trekkers have invested significant time, money and physical efforts in in their ventures and are determined to ascend despite early warning and illnesses. 2) Despite no history of altitude illnesses in previous altitude exposure,inter-current illness (in this case a nonspecific respiratory tract infection) may contribute to the development of high altitude pulmonary edema. 3) Continuing ascent using other transport means, whilst suffering from symptoms of high altitude illness, worsens the condition and could be life threatening. 4) Acetazolamide does not prevent high altitude pulmonary edema-perhaps more so in the cases that have inter-current illness. 5) Descent is the golden rule in all altitude illnesses. Actually 'descent' is advised in any undiagnosed illness at high altitude among sojourners. 6) Finally, an experienced guide who has mountain medicine training is essential. They can be crucial in noticing early signs and symptoms of altitude illnesses to inform the client's safety as in this case." }, { "id": "wiki20220301en624_4964", "title": "Leo Stern (historian)", "score": 0.008771929824561403, "content": "Halle" } ] } } }

Transthoracic (TTE) and transesophageal (TEE) echocardiography revealed abnormal, turbulent flow across the aortic prosthesis, which was probably caused by the presence of a pathological smooth and mobile structure (10 × 9 × 5 mm) in front of the aortic annulus. Blood cultures were positive and staphylococcal prosthetic valve endocarditis (PVE) was diagnosed. Despite antibiotic treatment, the patient's condition deteriorated, and he was referred for prosthesis reimplantation. After being transferred to the Cardiac Surgery Clinic, he presented with nausea, vomiting, and abdominal pain. The results of imaging examinations suggested spleen hematoma. The patient underwent an urgent splenectomy. Histopathological examination revealed a spleen infarction consequent to an embolic event and subscapular hematoma.

An emergency reoperation was undertaken for refractory heart failure in seven out of ten cases, with an average delay of 6.6 days after the beginning of antibiotic therapy. In the other three cases, the operation was carried out at the end of 40 days of antibiotic therapy, once for recurrent endocarditis and twice for severe aortic insufficiency. The most common causative micro organism was the staphylococcus (7 out of 10 cases). The infected prosthetic valves were, in 8 out of the 10 cases, in the aortic position. The outcome was poor as the mortality rate was 60% (6 out of the 7 patients operated on in an emergency). Death was attributed to heart failure with conduction disturbances and severe aortic regurgitation (2 cases), cerebral emboli (2 cases), septicopyemia (2 cases). Four patients of the ten, after a mean follow up of 10 months, are cured without prosthetic valve dysfunction. The extreme gravity of prognosis seems related to the microorganism (staphylococcus), to the delay between the beginning of antibiotic therapy and the onset of the fever, and finally to the extension of destructive lesions under the prosthetic valve implantation base; the reimplantation of the prosthesis on frail and abscessed tissue implies a substantial risk of disinsertion.

Rapidly progressive heart failure and presence of a friable-appearing vegetation on echocardiography were the indications for urgent operation. Preoperative electrocardiogram showed first degree A-V block. At operation the aortic valve was generally thickened with mild calcification about the commissures. Non-coronary cusp was severely deformed and was nearly detached at its base due to annular abscess formation. Native valve was completely excised and the abscess was debrided. A club or a tongue-shaped pedicled aortic wall flap was prepared to the left of the oblique aortotomy incision with its free end to the distal side of the aorta. The flap was folded inward at its pedicle about 1 cm above the non-coronary annulus and was used to patch the abscess cavity. The aortic valve was replaced with a SJM 23 mm aortic valve prosthesis. The remaining defect of the aortic wall was repaired with a patch of woven-dacron vascular prosthesis. Post-operative hemodynamics of the patient was uneventful and he was given a 6-week course of parenteral antibiotics. He developed complete A-V block during the operation, and a permanent pacemaker was implanted on the 6th postoperative day. One year after operation he has not had recurrent infection and is leading a normal life. When used in the repair of ventriculo-aortic discontinuity created by infective endocarditis, the pedicled aortic wall flap has several advantages. It is easily obtainable and can cover abscesses of almost any shape and size. Unlike aortic root homograft, there is no problem of availability. Technically it is relatively simple to prepare a flap, bring it down through the non-coronary sinus and suture over the abscess. Aortic wall has just appropriate thickness and strength to reinforce the weakened periannular area, and if the debrided cavity is deep, the flap can be folded to obtain double thickness. By using this flap, potentially infected cavity is covered and packed by autologous tissue alone, and the synthetic patch to repair the aortic wall defect is placed well away from the site of possible contamination. In addition to the use in infective endocarditis, the aortic wall flap can predictably be used in the repair of aortic annular defect created by over-zealous removal of calcium in the surgery of calcific aortic stenosis, and in intracardiac patching in aortic annular enlargement operation such as Manouguian operation.

No patients submitted to operation for acute/subacute bacterial endocarditis of the native aortic valve developed PE.

Seven of the nine infections with Staphylococcus albus were caused by a highly resistant nosocomial variant. Ten of the PE patients underwent replacement of the prosthesis while 14 were treated conservatively. The two therapeutic groups were comparable, although the surgically treated patients tended to be younger and to have more impaired cardiac status. All surgically treated patients and all patients treated conservatively and in whom post mortem verification was possible had paravalvular defects, annular abscesses and/or vegetations on the prosthesis. The thirty-day, one year and ten year cumulative survivals were 80%, 80% and 50%, respectively, after replacement of the prosthesis and 64%, 21% and 7%, respectively, after conservative treatment (p = 0.02). A Cox regression analysis identified conservative treatment, infection with Escherichia coli or Haemophilus influenzae and the need to intensify digitalis/diuretic treatment for congestive heart failure as independent risk factors.

Electrocardiographic evaluation was performed pre- and postprocedurally, and at 1-week and 1-month follow-up. Other clinical variables were obtained from the medical history, echocardiography, and angiography. After PAVI, 7 patients required PPI, all of whom developed total atrioventricular block within 3 days postprocedurally. A smaller left ventricular outflow tract diameter (20.3 +/- 0.5 vs 21.6 +/- 1.8 cm, P = .01), more left-sided heart axis (-20 degrees +/- 29 degrees vs 19 degrees +/- 36 degrees , P = .02), more mitral annular calcification (10 +/- 1 vs 5 +/- 4 mm, P = .008), and a smaller postimplantation indexed effective orifice area (0.86 +/- 0.20 vs 1.10 +/- 0.26 cm(2)/m(2), P = .04) were associated with PPI.

Percutaneous aortic valve implantation with the CoreValve prosthesis results in a high incidence of total atrioventricular block requiring PPI and new-onset LBBB. Preexisting disturbance of cardiac conduction, a narrow left ventricular outflow tract, and the severity of mitral annular calcification predict the need for permanent pacing, whereas the only factor shown to be predictive for new-onset LBBB is the depth of prosthesis implantation." }, { "id": "pubmed23n0321_6185", "title": "[Right-heart endocarditis after pacemaker implantation as a cause of a round pulmonary infiltrate].", "score": 0.00980392156862745, "content": "A 57-year-old man developed intermittent fever and fatigue 11 months after a two-chamber cardiac pacemaker had been implanted because of 2 degrees and 3 degrees A-V block.

Patients who needed an additional procedure such as another valve surgery, aortic surgery or coronary artery bypass grafting were excluded from the study. Permanent pacemaker implantation was required in 11 (6.9%) patients. The pacemaker was implanted after at least 7 days of complete AV block which was then considered permanent. Univariate analysis showed that permanent pacemaker implantation was associated with prolonged cardiopulmonary bypass time, prolonged aortic cross-clamp time, and the occurrence of electrolyte disturbances. Univariate logistic regression revealed that the need for permanent pacemaker implantation depended on 5 factors including prolonged cardiopulmonary bypass time, prolonged aortic cross-clamp time, larger size of the implanted valve prosthesis, endocarditis as the indication for surgery, and electrolyte disturbances. In both backward and forward stepwise multivariate regression models, two parameters, prolonged aortic cross-clamp time and the presence of electrolyte disturbances, correlated with the occurrence of complete AV block. Permanent complete AV block is a serious complication after aortic valve surgery.

The mean pre-procedural QRS duration was 101.7 ± 20.4 ms. More than one-half of the cohort (n = 111, 55%) developed new left bundle branch block (LBBB) following the procedure. Permanent pacemakers were implanted in 64 patients (32%) with a median time to insertion of 3.0 ± 3.4 days. Chief indications for pacing were atrioventricular (AV) block (n = 46, 72%), or LBBB with 1st degree AV block (n = 11, 17%). Amongst those who received a pacemaker following TAVR the pre-procedural electrocardiogram findings included: No conduction disturbance (n = 41, 64%); 1st degree AV block (n = 10, 16%); right bundle branch block (n = 6, 9%) and LBBB (n = 5, 8%). LBBB (but not permanent pacemaker) occurred more frequently in patients who had balloon aortic valvuloplasty before TAVR (odds ratio [OR]: 1.25; p = 0.03). Pre-procedural conduction abnormality (composite of 1st degree AV block, hemiblock, right bundle branch block, LBBB) was independently associated with the need for permanent pacemaker (OR: 2.54; p = 0.048). The absence of aortic valve calcification was also associated with a higher pacing rate (OR: 0.55; p = 0.031). Multivariate regression analysis did not show an independent association between depth of implant, valve oversizing, balloon post-dilatation, and the need for pacing post-procedure. Following implantation of the repositionable LOTUS valve, 55% of patients developed LBBB and 32% of patients required a pacemaker during their index hospital admission. Patients with pre-procedural conduction disturbance and non-calcified aortic valves were more likely to need pacing. No other anatomic features were identified with increased pacing requirement with the LOTUS device." }, { "id": "pubmed23n0103_4597", "title": "[Endocarditis on cardiac pacemaker endocavitary electrodes.

Cardiopulmonary bypass without cardiac standstill enabled dissection of the fibrous rings surrounding the catheter after purging the blood from the atrial and ventricular cavities. In one patient, associated tricuspid valve endocarditis was found and valvular replacement was performed with a bioprosthesis.

The correct answer is 5. An asymptomatic myoma of this size that does not deform the endometrial cavity is not a problem for pregnancy.
[HIDDEN] An asymptomatic myoma of this size that does not deform the endometrial cavity is not a problem for pregnancy.
A 32-year-old asymptomatic woman goes for a gynecological health check-up because she wishes to become pregnant. During this check-up, a 4cm uterine myoma is detected, partly intramural and partly subserosal, located on the anterior aspect of the uterus and which does not deform the endometrial cavity. What approach would you recommend?

Prospective RCTs have not been performed to compare the clinical results from UAE with more conventional therapies for symptomatic uterine leiomyomata. At least three attempts at conducting such RCTs have been unsuccessful because of poor patient accrual that related to differing patient expectation and desires, clinical bias, insurance coverage, and the tendency that patients who have exhausted other treatment options may be disposed more favorably to less invasive treatments. Other comparative studies have serious limitations. For example, the retrospective study that compared outcomes after abdominal myomectomy with UAE suggested that patients who received UAE were more likely to require further invasive treatment by 3 years than were recipients of myomectomy. Lack of randomization introduced a selection bias because women in the group that underwent UAEwere older and were more likely to have had previous surgeries. A prospective study of \"contemporaneous cohorts,\" which excluded patients who had sub-mucosal and pedunculated subserosal myomas, sought to compare quality of life measures and adverse events in patients who underwent UAE or hysterectomy. The investigators concluded that both treatments resulted in marked improvement in symptoms and quality of life scores, but complications were higher in the group that underwent hysterectomy over 1 year. In this study,however, a greater proportion of patients who underwent hysterectomy had improved pelvic pain scores. Furthermore, hysterectomy eliminates uterine bleeding and the risk for recurrence of myomas. Despite the lack of controlled studies that compared UAE with conventional surgery, and despite limited extended outcome data, UAE has gained rapid acceptance, primarily because the procedure preserves the uterus, is less invasive, and has less short-term morbidity than do most surgical options. The cost of UAE varies by region, but is comparable to the charges for hysterectomy and is less expensive than abdominal myomectomy. The evaluation before UAE may entail additional fees for diagnostic testing, such as MRI, to assess the uterine size and screen for adenomyosis. Other centers have recommended pretreatment ultrasonography, laparoscopy, hysteroscopy, endometrial biopsy, and biopsy of large fibroids to evaluate sarcoma. Generally,after UAE the recovery time and time lost from work are less; however, the potential need for subsequent surgery may be greater when compared with abdominal myomectomy. Any center that offers UAE should adhere to published clinical guidelines,maintain ongoing assessment of quality improvements measures, and observe strict criteria for obtaining procedural privileges. After McLucas advocated that gynecologists learn the skill to perform UAE for managing symptomatic myomas, the Society of Interventional Radiology responded with a precautionary commentary on the level of technical proficiency that is necessary to maintain optimum results from UAE. The complexity of pelvic arterial anatomy, the skill that is required to master modern coaxial microcatheters, and the hazards of significant patient radiation exposure were cited as reasons why sound training and demonstration of expertise be obtained before clinicians are credentialed to perform UAE.A collaboration between the gynecologist and the interventional radiologist is necessary to optimize the safety and efficacy of UAE. The primary candidates for this procedure include women who have symptomatic uterine fibroids who no longer desire fertility, but wish to avoid surgery or are poor surgical risks. The gynecologist is likely to be the primary initial consultant to patients who present with complaints of symptomatic myomas. Therefore, they must be familiar with the indications, exclusions, outcome expectations, and complications of UAE in their particular center. When hysterectomy is the only option, UAE should be considered. Appropriate diagnostic testing should aid in the exclusion of most, but not all, gynecologic cancers and pregnancy. Other contraindications include severe contrast medium allergy, renal insufficiency, and coagulopathy. MRI may be used to screen women before treatment in an attempt to detect those who have adenomyosis; patients should be aware that UAE is less effective in the presence of solitary or coexistent adenomyosis. Because some women may experience ovarian failure after UAE, additional studies to determine basal follicle-stimulating hormone and estradiol before and after the procedure may provide insight into UAE-induced follicle depletion.UAE is a unique new treatment for uterine myomas, and is no longer considered investigational for symptomatic uterine fibroids. There is international recognition that data are needed from RCTs that compare UAE with surgical alternatives. Current efforts to provide prospective objective assessment of treatment outcomes and complications after UAE will help to optimize patient selection and clinical guidelines. FIBROID should provide critical data for the assessment of safety and outcomes measures for women who receive UAE for symptomatic uterine myomas." }, { "id": "pubmed23n0537_4576", "title": "Myomas and assisted reproductive technologies: when and how to act?", "score": 0.016151866151866152, "content": "The effect of myomas on reproductive outcome has been the subject of many studies; however, a definitive answer is still missing. Therefore, the authors have tried to outline some guidelines for the management of women who have uterine myomas and desire to conceive. The location and size of the myomas are the two parameters that influence the success of a future pregnancy. Subserosal myomas seem to have little, if any,effect on reproductive outcome, especially if they are up to 5 to 7 cm in diameter. Intramural myomas that do not encroach upon the endometrium also can be considered to be relatively harmless to reproduction, if they are smaller than 4 to 5 cm in diameter. This is the ambiguous gray zone of the subject, and where research should be focused before a consensus can be established. Myomas that compress the uterine cavity with an intramural portion (submucous myoma type II) and submucous myomas significantly reduce pregnancy rates, and should be removed before assisted reproductive techniques are used. Hysteroscopic myomectomy is the gold standard for the treatment of submucous myomas. For other myomas, abdominal myomectomy, or laparoscopic myomectomy--when the experience of the surgeon and the facilities are sufficient--are the best alternatives. In most of the literature, the pregnancy rates were increased and the miscarriage rates were decreased after surgery with these two techniques. Other alternative treatment modalities, such as CUV, laparoscopic myolysis, or MRI-guided focused ultrasound, are to be monitored and evaluated thoroughly before they are applied as routine procedures." }, { "id": "pubmed23n1102_20141", "title": "Myoma Expulsion after Uterine Artery Embolization.", "score": 0.014609094535301157, "content": "Uterine leiomyomas are the most common benign pelvic tumors in women over 35 years and can be symptomatic or asymptomatic.

No significant impact of embolization on hormonal function has been reported in women less than 45 years with normal baseline function. UAE is not indicated for submucous myomas. Randomized studies comparing embolization to hysterectomy demonstrate that reinterventions are more frequently performed after embolization. Secondary hysterectomy is performed in 13 to 24 % of cases at 2 years and in up to 28 % of cases at 5 years.

Randomized studies comparing embolization to myomectomy demonstrate that in the short and mid-term there is no difference in terms of control of menorrhagia and bulk-related symptoms. Uterine volume reduction and quality of life were not different at 6 months. Periprocedural and 30-day complication rates are not different.

Hospital stay, duration of recovery and time off work are shorter after embolization compared to myomectomy. UAE is less aggressive than myomectomy and should be proposed as a conservative alternative treatment. Embolization should be considered with caution in pregnancy-seeking women since there is still a lack of good quality data available in the specific group of patients. FSH level is more frequently elevated after embolization compared to myomectomy. Pregnancy rate and term pregnancy rate are higher after myomectomy compared to embolization. Spontaneous abortion is more frequent after embolization than after myomectomy. At this time, UAE is not indicated excepted in studies or in specific cases when the woman want a pregnancy. Embolization performed before myomectomy (preoperative or combined procedures) can be discussed for an individual patient but there is not enough data to support its routine use.

Stepwise demonstration with narrated video footage. An academic tertiary care hospital affiliated with Baylor College of Medicine. Our patient is a 39-year-old pregnant G1P0010 with a symptomatic 12-cm degenerating pedunculated myoma refractory to conservative pain management. Recent literature has indicated that most laparotomic myomectomies performed during pregnancy showed overall positive pregnancy outcomes and low complications. This indicates that myomectomy in pregnancy is safe and can be used in cases unresponsive to conservative management [1]. However, cases in literature discussing the single-site techniques for laparoscopic myomectomy during pregnancy have been sparse [2]. Four case series were reviewed; a total of 62 pregnant patients underwent laparoendoscopic single-site surgery without any complications [3-6]. Using laparoscopy in myomectomy compared with laparotomy during pregnancy permits decreased postoperative pain, quicker recovery, and lowered risk of postoperative complications [5,7,8]. Single-site laparoscopic surgery also aids in improved patient cosmesis and can be used for the myoma removal. Literature has demonstrated that single-site laparoscopy is safe and feasible during all stages of pregnancy [3,4]. Nevertheless, this approach may be challenging for inexperienced surgeons owing to the lack of triangulation and crowding of instruments in single-site laparoscopy [5]. At 21 weeks and 3 days pregnancy, our patient underwent single-incision laparoscopic surgery myomectomy. A 2.5-cm skin incision was made at the umbilicus to the abdominal cavity, and a GelPOINT Mini was inserted. Through the laparoscope, we can observe that a 12-cm pedunculated myoma was protruding from the right uterine fundus on a 4-cm stalk. A 0-Vicryl suture was tied around the base of the stalk. The stalk was then cauterized with bipolar energy and transected with the harmonic scalpel, completely detaching the myoma. Subsequently, an Endo Catch bag was placed around the myoma and brought up to the umbilical incision. Using a scalpel, bag-contained morcellation was completed within 22 minutes and the contents removed. As a result, the estimated blood loss was 50 cc and the total operative time was 123 minutes. The extended operating time was caused by slow movements to avoid disrupting the fetus. She had an unremarkable postoperative course, no medications were needed for pain management, and she was discharged home on postoperative day 2. At 38 weeks, she successfully delivered with elective cesarean delivery with no complications. Histopathology showed fragments of leiomyoma with diffuse necrosis. Tips and tricks: 1. Single-site entry technique uses the open Hasson technique, which reduces the risk of injury to the pregnant uterus and dilated surrounding vessels. 2. Through a 2.5-cm incision, the surgeon placed a suture in the myoma stalk because other hemostasis agents such as vasopressin are contraindicated in pregnancy. 3. Owing to difficulties related to single-site surgery, the surgeon should possess extensive expertise in single-site surgery. 4. Manipulation of the uterus should be minimized to reduce the disturbance of the pregnant uterus. 5. V-loc suture allows for faster and simplified uterine incision closure. 6. If the surgeon encounters excessive difficulty during the surgery, a 5-mm accessory port can be placed. 7. During tissue extraction, gentle traction should be used to reduce provoking the pregnant uterus. 8. When transecting the myoma stalk, it is important to leave a stump of more than 1 cm to increase suturing ease and prevent accidental suturing of the uterus. Single-incision laparoscopic surgery myomectomy for pedunculated myoma may be a practical technique in women refractive to conservative management. When performed by an experienced surgeon, the patient may benefit from faster specimen removal and recovery." }, { "id": "pubmed23n0416_15708", "title": "[Management of uterine myomas in women of fertile age].", "score": 0.009900990099009901, "content": "Review of current knowledge about uterine fibroids management in young women.

Department of Obstetrics and Gynecology, 1st Faculty of Medicine and the General Faculty Hospital, Charles University, Prague. Analysis of the facts in literature (texts in medical journals, monographies, textbooks, internet database Medline and Ovid) and authors' clinical experience. Alternatives of treatment of infertility in women with uterine fibroids have significantly enlarged in past 10 years. However none of the indicated methods is perfect. Expectation does not exclude the risk of growth of fibroids and abortion. The effect of pharmacological therapy is only temporary. Myomectomy is associated with the risk of surgical complications, fibroids' recurrence and uterine rupture in subsequent gestation. Although uterine artery embolisation (on an average) halves the fibroids volume, the long-term effect of the method on female fertility is still unknown. Nevertheless it seems convenient to advise the active approach to all women planning pregnancy and having significant (submucous or intramural) fibroid even before spontaneous or assisted conception. Most recent studies indicate significant improvement of reproduction outcomes after myomectomy, especially in young women with the absence of other factors of infertility. Only the results of randomized, controlled trials (that are still awaited) will inform us about comparison of the effects and risks of myomectomy and uterine artery embolization in management of infertility." }, { "id": "pubmed23n0968_18287", "title": "Port site parasitic leiomyoma after laparoscopic myomectomy: a case report and review of the literature.", "score": 0.00980392156862745, "content": "Uterine fibroids are the commonest benign gynecological tumors. Laparoscopic myomectomy is becoming increasingly popular as one of the surgical treatment options for symptomatic cases. Large tissues such as leiomyomas or even the uterus need to be morcellated in order to be retrieved from the abdominal cavity. Some of the morcellated fragments or small fibroids may be accidentally left in the abdominal cavity during the retrieval process. These may subsequently become implanted in the abdominal cavity, develop blood supply from the surrounding structures, and grow to form parasitic myomas with varied clinical presentation, depending on the location and size. A 47-year-old African woman presented to our hospital 6 years after laparoscopic myomectomy with a lower abdominal mass. Her work-up revealed an anterior abdominal wall mass consistent with uterine leiomyoma. She was scheduled for excision of the mass, which was subsequently histologically confirmed to be a uterine fibroid. Parasitic leiomyomas are a rare late complication of power morcellation following laparoscopic myomectomy or hysterectomy. Most patients present with an abdominal/pelvic mass and may need surgical excision to relieve the symptoms. Care should be taken during power morcellation to prevent excessive fragmentation of the tissues, some of which may become implanted and persist to form parasitic myomas. Moreover, effort should be made to retrieve all myoma fragments by carefully checking the abdominal cavity. Whenever possible, the morcellation should be done in a containment bag." }, { "id": "pubmed23n0619_19880", "title": "[New options in the diagnosis and management of uterine myoma].", "score": 0.00980392156862745, "content": "Myoma accounts for nearly 95% of all benign tumors of female genital organs and is the most common neoplasm of female genital tract.

A number of therapeutic options are available for the management of myoma, ranging from medicamentous therapy through operative procedures (e.g., total or supracervical hysterectomy or myoma enucleation) and novel non-operative procedures (e.g., embolization of uterine artery (EUA) and magnetic resonance guided focused ultrasound (MRgFUS). Discomforts caused by a myoma are an absolute indication for treatment. Therapeutic option to be chosen is determined by the number, size and location of myomas, and the patient's preferences.

Usual and novel treatment options for fibroids will be reviewed with emphasis on their applicability in women who wish to conceive. Management of fibroids in women wishing to conceive first involves documentation of the presence of the fibroid and determination of likelihood of the fibroid impacting on the ability to conceive. Treatment of fibroids in this instance is primarily surgical, but must be weighed against the evidence of surgical management improving clinical outcomes, and risks specific to surgical management and approach. The outcomes of primary concern are the improvement in pregnancy rates and outcomes with management of fibroids in women with infertility. Published literature was retrieved through searches of PubMed, MEDLINE, the Cochrane Library in November 2013 using appropriate controlled vocabulary (e.g., leiomyoma, infertility, uterine artery embolization, fertilization in vitro) and key words (e.g., fibroid, myomectomy). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies published in English and French. There were no date restrictions. Searches were updated on a regular basis and incorporated in the guideline to November 2013. Grey (unpublished literature) was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The quality of evidence in this document was rated using the criteria described by the Canadian Task Force on Preventive Health Care (Table). These recommendations are expected to allow adequate management of women with fibroids and infertility, maximizing their chances of pregnancy by minimizing risks introduced by unnecessary myomectomies. Reducing complications and eliminating unnecessary interventions are also expected to decrease costs to the health care system. Summary Statements 1. Subserosal fibroids do not appear to have an impact on fertility; the effect of intramural fibroids remains unclear. If intramural fibroids do have an impact on fertility, it appears to be small and to be even less significant when the endometrium is not involved. (II-3) 2. Because current medical therapy for fibroids is associated with suppression of ovulation, reduction of estrogen production, or disruption of the target action of estrogen or progesterone at the receptor level, and it has the potential to interfere in endometrial development and implantation, there is no role for medical therapy as a stand-alone treatment for fibroids in the infertile population. (III) 3. Preoperative assessment of submucosal fibroids is essential to the decision on the best approach for treatment. (III) 4. There is little evidence on the use of Foley catheters, estrogen, or intrauterine devices for the prevention of intrauterine adhesions following hysteroscopic myomectomy. (II-3) 5. In the infertile population, cumulative pregnancy rates by the laparoscopic and the minilaparotomy approaches are similar, but the laparoscopic approach is associated with a quicker recovery, less postoperative pain, and less febrile morbidity. (II-2) 6. There are lower pregnancy rates, higher miscarriage rates, and more adverse pregnancy outcomes following uterine artery embolization than after myomectomy. (II-3) Studies also suggest that uterine artery embolization is associated with loss of ovarian reserve, especially in older patients. (III) Recommendations 1. In women with infertility, an effort should be made to adequately evaluate and classify fibroids, particularly those impinging on the endometrial cavity, using transvaginal ultrasound, hysteroscopy, hysterosonography, or magnetic resonance imaging. (III-A) 2. Preoperative assessment of submucosal fibroids should include, in addition to an assessment of fibroid size and location within the uterine cavity, evaluation of the degree of invasion of the cavity and thickness of residual myometrium to the serosa. A combination of hysteroscopy and transvaginal ultrasound or hysterosonography are the modalities of choice. (III-B) 3. Submucosal fibroids are managed hysteroscopically. The fibroid size should be &lt; 5 cm, although larger fibroids have been managed hysteroscopically, but repeat procedures are often necessary. (III-B) 4. A hysterosalpingogram is not an appropriate exam to evaluate and classify fibroids. (III-D)  5. In women with otherwise unexplained infertility, submucosal fibroids should be removed in order to improve conception and pregnancy rates. (II-2A) 6. Removal of subserosal fibroids is not recommended. (III-D) 7. There is fair evidence to recommend against myomectomy in women with intramural fibroids (hysteroscopically confirmed intact endometrium) and otherwise unexplained infertility, regardless of their size. (II-2D) If the patient has no other options, the benefits of myomectomy should be weighed against the risks, and management of intramural fibroids should be individualized. (III-C) 8. If fibroids are removed abdominally, efforts should be made to use an anterior uterine incision to minimize the formation of postoperative adhesions. (II-2A) 9. Widespread use of the laparoscopic approach to myomectomy may be limited by the technical difficulty of this procedure. Patient selection should be individualized based on the number, size, and location of uterine fibroids and the skill of the surgeon. (III-A) 10. Women, fertile or infertile, seeking future pregnancy should not generally be offered uterine artery embolization as a treatment option for uterine fibroids.

The areas of clinical practice considered in formulating this guideline were assessment, medical treatments, conservative treatments of myolysis, selective uterine artery occlusion, and surgical alternatives including myomectomy and hysterectomy. The risk-to-benefit ratio must be examined individually by the woman and her health care provider. Implementation of this guideline should optimize the decision-making process of women and their health care providers in proceeding with further investigation or therapy for uterine leiomyomas, having considered the disease process and available treatment options, and reviewed the risks and anticipated benefits. Published literature was retrieved through searches of PubMed, CINAHL, and Cochrane Systematic Reviews in February 2013, using appropriate controlled vocabulary (uterine fibroids, myoma, leiomyoma, myomectomy, myolysis, heavy menstrual bleeding, and menorrhagia) and key words (myoma, leiomyoma, fibroid, myomectomy, uterine artery embolization, hysterectomy, heavy menstrual bleeding, menorrhagia). The reference lists of articles identified were also searched for other relevant publications. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies.

Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, and national and international medical specialty societies. The majority of fibroids are asymptomatic and require no intervention or further investigations. For symptomatic fibroids such as those causing menstrual abnormalities (e.g. heavy, irregular, and prolonged uterine bleeding), iron defficiency anemia, or bulk symptoms (e.g., pelvic pressure/pain, obstructive symptoms), hysterectomy is a definitive solution. However, it is not the preferred solution for women who wish to preserve fertility and/or their uterus. The selected treatment should be directed towards an improvement in symptomatology and quality of life. The cost of the therapy to the health care system and to women with fibroids must be interpreted in the context of the cost of untreated disease conditions and the cost of ongoing or repeat investigative or treatment modalities. The quality of evidence in this document was rated using the criteria described in the Report of the Caadian Task Force on Preventive Health Care (Table 1). Summary Statements 1. Uterine fibroids are common, appearing in 70% of women by age 50; the 20% to 50% that are symptomatic have considerable social and economic impact in Canada. (II-3) 2. The presence of uterine fibroids can lead to a variety of clinical challenges. (III) 3. Concern about possible complications related to fibroids in pregnancy is not an indication for myomectomy except in women who have had a previous pregnancy with complications related to these fibroids. (III) 4. Women who have fibroids detected in pregnancy may require additional maternal and fetal surveillance. (II-2) 5. Effective medical treatments for women with abnormal uterine bleeding associated with uterine fibroids include the levonorgestrel intrauterine system, (I) gonadotropin-releasing hormone analogues, (I) selective progesterone receptor modulators, (I) oral contraceptives, (II-2) progestins, (II-2) and danazol. (II-2) 6. Effective medical treatments for women with bulk symptoms associated with fibroids include selective progesterone receptor modulators and gonadotropin-releasing hormone analogues. (I) 7. Hysterectomy is the most effective treatment for symptomatic uterine fibroids. (III) 8. Myomectomy is an option for women who wish to preserve their uterus or enhance fertility, but carries the potential for further intervention. (II-2) 9. Of the conservative interventional treatments currently available, uterine artery embolization has the longest track record and has been shown to be effective in properly selected patients. (II-3) 10. Newer focused energy delivery methods are promising but lack long-term data. (III) Recommendations 1. Women with asymptomatic fibroids should be reassured that there is no evidence to substantiate major concern about malignancy and that hysterectomy is not indicated. (III-D) 2. Treatment of women with uterine leiomyomas must be individualized based on symptomatology, size and location of fibroids, age, need and desire of the patient to preserve fertility or the uterus, the availability of therapy, and the experience of the therapist. (III-B) 3. In women who do not wish to preserve fertility and/or their uterus and who have been counselled regarding the alternatives and risks, hysterectomy by the least invasive approach possible may be offered as the definitive treatment for symptomatic uterine fibroids and is associated with a high level of satisfaction. (II-2A) 4. Hysteroscopic myomectomy should be considered first-line conservative surgical therapy for the management of symptomatic intracavitary fibroids. (II-3A) 5. Surgical planning for myomectomy should be based on mapping the location, size, and number of fibroids with the help of appropriate imaging. (III-A) 6. When morcellation is necessary to remove the specimen, the patient should be informed about possible risks and complications, including the fact that in rare cases fibroid(s) may contain unexpected malignancy and that laparoscopic power morcellation may spread the cancer, potentially worsening their prognosis. (III-B) 7. Anemia should be corrected prior to proceeding with elective surgery. (II-2A) Selective progesterone receptor modulators and gonadotropin-releasing hormone analogues are effective at correcting anemia and should be considered preoperatively in anemic patients. (I-A) 8. Use of vasopressin, bupivacaine and epinephrine, misoprostol, peri-cervical tourniquet, or gelatin-thrombin matrix reduce blood loss at myomectomy and should be considered. (I-A) 9. Uterine artery occlusion by embolization or surgical methods may be offered to selected women with symptomatic uterine fibroids who wish to preserve their uterus. Women choosing uterine artery occlusion for the treatment of fibroids should be counselled regarding possible risks, including the likelihood that fecundity and pregnancy may be impacted. (II-3A) 10. In women who present with acute uterine bleeding associated with uterine fibroids, conservative management with estrogens, selective progesterone receptor modulators, antifibrinolytics, Foley catheter tamponade, and/or operative hysteroscopic intervention may be considered, but hysterectomy may become necessary in some cases. In centres where available, intervention by uterine artery embolization may be considered.

This technique was introduced in the 1990s to help manage severe chronic pain and improve the opioid response in cancer patients. In order to obtain adequate levels of pain relief, patients requiring chronic opioid therapy may require an increase in the original prescribed dose for a number of reasons, including increased pain or a worsening disease state. Over the course of long term treatment, an increase in dosage cannot be continued indefinitely as unwanted side effects of treatment often become intolerable once a certain dose is reached, even though the pain may still not be properly managed. One strategy used to address this is to switch the patient between different opioid drugs over time, usually every few months.

In general, cancer pain treatment is far from being optimal for many patients. To date, morphine remains the gold standard as first-line therapy, but other pure μ agonists such as hydromorphone, fentanyl, or oxycodone can be considered. Transdermal opioids are an important option if the oral route is impossible. Due to its complex pharmacology, methadone should be restricted to patients with difficult pain syndromes. The availability of a fixed combination of oxycodone and naloxone is a promising development for the reduction of opioid induced constipation. Especially bone metastases often result in breakthrough pain episodes. Thus, the provision of an on-demand opioid (e.g., immediate-release morphine or rapid-onset fentanyl) in addition to the baseline (regular) opioid therapy (e.g., sustained-release morphine tablets) is mandatory. Recently, rapid onset fentanyls (buccal or nasal) have been strongly recommended for breakthrough cancer pain due to their fast onset and their shorter duration of action. If available, metamizole is an alternative non-steroid-anti-inflammatory-drug. The indication for bisphosphonates should always be checked early in the disease. In advanced cancer stages, glucocorticoids are an important treatment option. If bone metastases lead to neuropathic pain, coanalgetics (e.g., pregabalin) should be initiated. In localized bone pain, radiotherapy is the gold standard for pain reduction in addition to pharmacologic pain management. In diffuse bone pain radionuclids (such as samarium) can be beneficial. Invasive measures (e.g., neuroaxial blockage) are rarely necessary but are an important option if patients with cancer pain syndromes are refractory to pharmacologic management and radiotherapy as described above. Clinical guidelines agree that cancer pain management in incurable cancer is best provided as part of a multiprofessional palliative care approach and all other domains of suffering (psychosocial, spiritual, and existential) need to be carefully addressed («total pain»)." }, { "id": "wiki20220301en269_37542", "title": "Metastatic breast cancer", "score": 0.012800097991180794, "content": "Liver metastases.

Nonopioids were recommended for mild pain, with the addition of mild opioids for moderate pain and strong opioids for severe pain. Here, we review the evidence for the use of nonopioid analgesic agents in patients with cancer and describe the mode of action of the main drug classes. Evidence supports the use of anti-inflammatory drugs such as acetaminophen/paracetamol and nonsteroidal anti-inflammatory drugs (NSAIDs) for mild cancer pain. Adding an NSAID to an opioid for stronger cancer pain is efficacious, but the risk of long-term adverse effects has not been quantified. There is limited evidence to support using acetaminophen with stronger opioids. Corticosteroids have a specific role in spinal cord compression and brain metastases, where improved analgesia is a secondary benefit. There is limited evidence for adding corticosteroids to stronger opioids when pain control is the primary objective. Systematic reviews suggest a role for antidepressant and anticonvulsant medications for neuropathic pain, but there are methodologic issues with the available studies.

For cancer pain oral analgesics are efficacious in more than 90% of the patients. When a causal therapy of pain (e.g. chemotherapy, operation) fails an analgesic ladder with oral analgesics is instituted. This ladder starts with a non-narcotic analgesic in a sufficient dose. The regular dose of acetylsalicylic acid or paracetamol is 4 g daily. When this dose does not work sufficiently, a weak opioid (e.g. dihydrocodeine) is given concomitantly at an individual dose. When the weak opioid fails, strong opioids are given (e.g. morphine). The drugs should be given by mouth whenever possible. The most important point is the regular application according to a time-schedule. This time-schedule is related to the action time of the drug. Patients with severe vomiting or dysphagia can receive a continuous subcutaneous infusion. These measures are based on recommendations of the WHO.The same medications can be employed in patients with chronic non-malignant pain, provided that all other conventional measures in pain treatment fail. However, many states of pain are not opioid-responsive. Pain related to the sympathetic nervous system is more responsive to antidepressants than to opioids or NSAID. Neuropathic pain as in trigeminal neuralgia responds to anticonvulsants. Pain from muscle spasm is better controlled by muscle relaxants than by analgesics. Bone pain is more sensitive to NSAID than to any other drug.In any state of pain the response to the different groups of drugs should be evaluated first.

Bone metastasis causes skeletal-related events(SREs), including pain, bone fractures, spinal cord compression, and hypercalcemia. SREs significantly impair patients' quality of life. The main purpose of treatment for bone metastasis is to prevent or delay SREs and to improve patients' quality of life. Accurate diagnosis of bone metastases is important in order to choose an appropriate treatment. Treatment of bone metastasis requires a multidisciplinary approach. Analgesic medication with NSAIDs and opioids is the first choice for pain control. In addition to bisphosphonate, the receptor activator of the nuclear factor κB ligand(RANKL)inhibitor, denosumab is a novel bone-targeting agent effective in preventing SREs. Prophylactic stabilization of impending fractures provides several advantages compared with fixation of an acute fracture, in terms of short hospitalization and a quick return to baseline.

From December 1988 to March 1994, 205 patients with a total of 255 solitary or multiple bone metastases from several primary tumors were treated in our radiotherapy center with palliative intent. Irradiation fields were treated with three main fractionation schedules: (1) Conventional fractionation: 40-46 Gy/20-23 fractions in 5-5.5 weeks; (2) Short course: 30-36 Gy/10-12 fractions in 2-2.3 weeks; (3) Fast course: 8-28 Gy/1-4 consecutive fractions. Pain intensity was self-assessed by patients using a visual analogic scale graduated from 0 (no pain) to 10 (the strongest pain one can experience). Analgesic requirement was assessed by using a five-point scale, scoring both analgesic strength and frequency (0 = no drug or occasional nonopioids; 1 = Nonopioids once daily; 2 = Nonopioids more than once daily; 3 = Mild opioids (oral codeine, pentazocine, etc.), once daily; 4 = Mild opioids more than once daily; 5 = Strong opioids (morphine, meperidine, etc.). Complete pain relief meant the achievement of a score &lt; or = 2 in the pain scale or 0 in the analgesic requirement scale. Partial pain relief indicated a score of 3 to 4 or of 1 to 2 on the former and latter scale, respectively. Total pain relief (complete + partial) was observed in 195 (76%) sites, in 158 of which (62%) a complete response was obtained. Metastases from NSC lung tumors appeared to be the least responsive among all primary tumors, with 46% complete pain relief in comparison to 65% and 83% complete relief in breast (p = 0.04) and in prostate metastases (p = 0.002), respectively. A significant difference in pain relief was detected among the several ranges of total dose delivered to the painful metastases, with 81%, 65%, and 46% complete relief rates in the 40-46 Gy, 30-36 Gy (p = 0.03), and 8-28 Gy (p = 0.0001) dose ranges respectively. A straight correlation between total dose and complete pain relief was confirmed by the curve calculated by the logistic model which shows that doses of 30 Gy or more are necessary to achieve complete pain relief in 70% or more of bone metastases. This correlation holds also for the duration of pain control, as shown by the actuarial analysis of time to pain progression. Multivariate analyses, with complete pain relief and time to pain progression as endpoints show a highly significant effect of radiation dose (p = 0.0007) and performance status (p = 0.003), with lower rates of complete pain relief and shorter time to pain progression observed after smaller radiation total doses or higher Eastern Cooperative Oncology Group (ECOG) scores.

Conventional therapies to relieve metastatic bone pain include nonopioid and opioid analgesics, hormonal therapy, external-beam irradiation, and chemotherapy. Limitations in the long-term safety and effectiveness of these treatments have increased interest in using systemic radioactive isotopes for palliation of pain. Strontium chloride Sr 89 is a relatively new bone-seeking radiopharmaceutical that has FDA-approved labeling for use in relieving pain associated with skeletal metastases. An analogue of calcium, strontium chloride Sr 89 is rapidly cleared from the blood after i.v. injection. The agent selectively irradiates metastatic sites while generally sparing normal soft-bone tissue. In clinical studies, a majority of patients with prostate or breast cancer obtained substantial relief from bone pain after receiving strontium chloride Sr 89 alone or in combination with external-beam irradiation. Adverse effects tend to be mild, but patients should be monitored for possible hematologic toxicity. Patients should discontinue any calcium-containing products before receiving the agent. The typical dose is 4 mCi (148 MBq) administered by slow i.v. push over one to two minutes; doses can be repeated at three-month intervals. Pain relief usually begins in 10-20 days and lasts up to six months. Radiation safety measures are necessary in handling strontium chloride Sr 89 and the wastes of patients.

Although this group of diseases are highly susceptible to chemotherapy, prognosis depends on the type of GTN and whether the tumor has spread to other areas of the body. Cause and Risk factors The exact cause of gestational trophoblastic neoplasia (GTN) is unknown. GTN often arises after molar pregnancies but can also occur after any gestation including miscarriages and term pregnancies. Although risk factors may impact on the development of the tumor, most do not directly cause of disease. According to the some studies, the risk of complete molar pregnancy is highest in women over age 35 and younger than 20. The risk is even higher for women over age 45.

This standard effectively detects all disease recurrence; however, it is resource intensive, delays child bearing, and is subject to significant noncompliance. Our objective was to determine the risk of disease recurrence after hCG spontaneously declines to undetectable levels. We used a database from the New England Trophoblastic Disease Center to analyze hCG levels in patients with complete molar pregnancies. Among 1,029 women with complete molar pregnancy and complete data, 15% developed persistent gestational trophoblastic neoplasia. The rate of persistent neoplasm among those whose hCG level fell spontaneously to undetectable levels was 0.2% (2/876, 95% confidence interval 0-0.8%). No women developed persistent gestational trophoblastic neoplasia after their hCG level fell to undetectable levels using an assay with a sensitivity of 5 mIU/mL (n = 82, 95% confidence interval 0-4.5%).

High-risk patients should be treated with multi-agent chemotherapy EMA/CO, with selective use of surgery and radiotherapy (II-3B). Salvage chemotherapy with EP/EMA and surgery should be employed in resistant disease (III-C). 5.

Without treatment, it goes through the following stages: primary, secondary, latent, and tertiary (1). The clinical picture of secondary syphilis is very variable (2,3). We present two rare cases of secondary syphilis, one with nodular lesions initially considered to be lymphoma and second with periostitis, which was initially interpreted as an osteoma. To date, only 15 cases with nodular lesions and 10 cases with periostitis in secondary syphilis have been reported in the literature. The first patient was a 59 year old man who presented in a private practice with nodular lesions on the face and axillary and inguinal folds (Figure 1, a, b). The initial diagnostic consideration was lymphoma. A biopsy specimen was taken, and the histopathological features revealed epidermal hyperplasia with papillomatosis, minimal spongiosis with many neutrophils and with a marked inflammatory infiltrate in dermis, consisting of lymphocytes, plasma cells, and neutrophils; the diagnosis of interfaced dermatitis was established (Figure 1, d, e). After one month, the patient presented to our clinic with numerous nodular lesions, some of them painful, located on the trunk and intertriginous folds, including the intergluteal cleft - the lesions in this area being suggestive of condylomata lata (Figure 1, c). The diagnosis of secondary syphilis was taken into consideration, and screening serum tests were performed and found reactive: a Venereal Diseases Research Laboratory (VDRL) titer of 1:64 and Treponema pallidum Hemaglutination Assay (TPHA) titer of 1:80. Hepatitis and anti-human immunodeficiency virus (HIV) antibodies serology was negative. The biopsy was repeated and showed the same histopathological changes. In addition, Warthin-Starry staining was performed, revealing the presence of some spiral micro-organisms in the dermis corresponding to Treponema pallidum (Figure 1, f). A diagnosis of secondary syphilis was established, and the patient was treated with benzathine penicillin G 2.4 million units by intramuscular injection once a week for 2 consecutive weeks. The skin lesions regressed within 1 month, and serological tests showed a VDRL titer of 1:8 3 months after treatment. The second patient was a homosexual male, 35 years old, diagnosed with HIV infection, stage B2. He presented with bone pain in the calves and forearms, with insidious onset. He also presented with an associated erythematous maculo-papular rash on the trunk and limbs and generalized lymphadenopathy (Figure 2, a, b). The tibial crest and radius were sensitive to palpation. A right leg radiography was performed, raising suspicion of osteoid osteoma. The CT scan excluded the diagnosis of osteoma; taking into account the epidemiological context, the diagnosis of syphilis was suspected. The diagnosis was confirmed by leg ultrasound examination (2D US) which showed thickening of the compact tibial bone associated with subperiosteal destructive and proliferative changes (Figure 2, c, d) and by serology for syphilis: the VDRL titer was 1:32 and the TPHA titer was 1:80. The patient was treated with benzathine penicillin 2.4 million units, once a week, for 2 consecutive weeks, with clinical improvement. Syphilis continues to be a serious public health problem worldwide, even if it is a controllable disease due to diagnostic tests and effective and accessible treatment. According to the World Health Organization in 2008, the estimated number of new cases of sexually transmitted diseases in adults with syphilis is 10.6 million cases (4). The cases presented in this paper were characterized by unusual manifestations, requiring good collaboration between the dermatologist and other specialties. In the first case, the diagnosis of secondary syphilis was confirmed by positive serological, clinical, and histopathological findings. The main differential diagnosis of nodular syphilis includes lymphoma, sarcoidosis, Kaposi's sarcoma, atypical mycobacteriosis, deep fungal infections, leprosy, tuberculosis, leishmaniasis, and lymphomatoid papulosis (5). Another important differential diagnosis is between secondary and tertiary syphilis, especially when ulcerating nodules are present. Tertiary syphilis is characterized by unilateral, deep ulcerating nodules with necrotizing granulomas (6). Bone involvement during syphilis is mainly represented by polyarthritis, synovitis, osteitis, and periostitis (7,8). Syphilitic periostitis is characterized by localized or diffuse pain, particularly during the night, which is relieved by movement. The skull, the shoulder girdle, and the long bones are the most common sites of involvement (9). In conclusion, we presented two different cases of secondary syphilis that contribute to the clinical experience of rare cases presented in the literature, raising the awareness of dermatologists and other specialists about less specific clinical aspects of syphilis." }, { "id": "article-28956_53", "title": "Sexually Transmitted Infections -- History and Physical -- Lymphogranuloma venereum (LGV)", "score": 0.009615384615384616, "content": "Females and males: Signs and symptoms: Patients will present with painful lymphadenopathy localized to the inguinal area.

This question corresponds to the section on traumatology; however, it could be answered with knowledge of rheumatology and with the osteoporosis recommendations of the Spanish Society of Rheumatology. In osteoporosis, one of the main risks associated with increased fracture risk is low adherence to treatment, so answer 1 is correct. Answer 2 is found in the SER guidelines, which confirm that some studies conclude that bone remodeling markers can be useful for early monitoring of adherence and response to treatment. Answer 4 is correct because again in the SER 2019 guidelines they quote: "The current scientific evidence allows us to affirm that neither increasing dietary calcium nor taking calcium supplements alone protects against the appearance of fractures". Therefore, the correct answer to this question is option 3. Patients on pharmacological treatment for OP should use calcium and vitamin D supplements because practically all clinical trials that have demonstrated efficacy of antiosteoporotic drugs routinely include calcium supplements and cholecalciferol (vitamin D3), but not in monotherapy.

Tomorrow the situation will clearly be worse because the continual increase in life expectancy will cause a 3-fold rise in worldwide fracture incidence over the next 60 years, particularly in women, but also in men. In addition, a secular increase in the incidence of hip fractures in individuals of the same age has been noted in both sexes by several investigators, and the cost of hip fractures is expected to dramatically increase in the next decades. Consequently, preventive strategies are urgently required. A great deal has been learned in recent years about the risk factors for hip fracture, the pathophysiology of this fracture, and the prediction of fracture risk, particularly through bone mass measurements on the hip and biochemical evaluations of parathyroid and vitamin D status. The two main determinants of hip fractures are falls and bone loss leading to an intrinsic femoral fragility. A substantial femoral bone loss continues throughout the old age, with a continuous and exponential increase in the risk of hip fracture, and any reduction or arrest of this loss will induce an important reduction in the incidence of hip fractures. A preventive effect on the risk of hip fracture may be partly achieved by using long term estrogen replacement therapy after menopause, but also by using vitamin D and calcium supplements for a late prevention in elderly people. Vitamin D insufficiency and deficit in calcium intake are very common in elderly people living either in institutions or at home, particularly in Europe where dairy products are not fortified with vitamin D. The cumulative response to this deficit in calcium intake and low vitamin D status is a negative calcium balance which stimulates parathyroid hormone secretion. In 300 residents of nursing homes, we recently found a significant negative correlation between serum 25 OHD and log serum PTH after age-adjustment. In addition, in 446 elderly women living at home in 5 French cities and selected from the voting lists, we also found an age-adjusted relationship between serum 25 OHD and PTH concentrations. This senile secondary hyperparathyroidism is one of the determinants of femoral bone loss and can be reversed by calcium and vitamin D supplements. We have shown in a 3-year controlled prospective study that the daily use of these supplements (1.2 g of calcium and 800 IU of vitamin D3) given in a large population of 3270 elderly ambulatory women living in nursing homes reduced of 23% (intention-to-treat analysis) the number of hip fractures and other non vertebral fractures. In parallel, serum perathyroid hormone concentration was reduced of 28% and low serum 25-hydroxyvitamin D concentration returned to normal values. After 18 months of treatment the bone density of the total proximal femoral region had increased 2.7% the vitamin D3-calcium group and decreased 4.6% in the placebo group (p &lt; 0.001). This prevention is safe and can be recommended in people living in institutions. It could be also useful in other elderly subjects particularly at risk because of a low calcium intake, an absence of solar exposure and a previous history of falls. From the data of our study we assessed the economic consequences in terms of medical cost of this prevention. In case of treatment of all women living in nursing homes in France, this would saved FF 150000000 per year, the economic balance of prevention becoming positive as soon as the age of the beginning of the prevention reaches 73.5 years. It is now possible to partly stop bone loss in elderly people and it is never too late to prevent hip fractures with calcium and vitamin D supplements." }, { "id": "pubmed23n0655_3344", "title": "Efficacy of vitamin D3 supplementation in preventing fractures in elderly women: a meta-analysis.", "score": 0.016662057522123894, "content": "The efficacy of vitamin D(3) in preventing fractures and falls has been explored in a number of clinical trials.

Medline and EMBASE were searched for controlled trials comparing the effectiveness of cholecalciferol (vitamin D(3)) against placebo with or without background calcium supplementation in the treatment of postmenopausal women. Eight controlled trials evaluating the effect of vitamin D(3) supplementation with or without calcium were assessed. Of 12 658 women included in a Bayesian meta-analysis, 6089 received vitamin D(3) (with or without calcium) and 6569 received placebo (with or without calcium). Compared to placebo, vitamin D(3) with calcium supplementation showed beneficial effects on the incidence of non-vertebral (odds ratio [OR] 0.77, 95% credibility limit [CL] 0.6-0.93) and hip (OR 0.70, 95% CL 0.53-0.90) fractures, while the effects on non-vertebral-non-hip fractures (OR 0.84, 95% CL 0.67-1.04) % point increase) were associated with more uncertainty. Vitamin D(3) supplementation showed a 70% probability of being a better treatment than placebo for the prevention of non-vertebral fractures, hip fractures, and non-vertebral, non-hip fractures. Compared to calcium supplementation, vitamin D(3) plus calcium reduced non-vertebral fractures (OR 0.68, 95% CL 0.43-1.01) and non-vertebral, non-hip fractures (OR 0.64, 95% CL 0.38-0.99), but did not reduce hip fractures (OR 1.03, 95% CL 0.39-2.25). Key limitations to this analysis include a small number of studies and heterogeneity in the study populations. This meta-analysis supports the use of vitamin D3 of 800 IU daily to reduce the incidence of osteoporotic non-vertebral, hip, and non-vertebral-non-hip fractures in elderly women. Vitamin D(3) with calcium appears to achieve benefits above those attained with calcium supplementation alone for non-vertebral and non-vertebral-non-hip fractures." }, { "id": "pubmed23n0275_4712", "title": "Prevention of hip fractures.", "score": 0.016387959866220735, "content": "For a 50-year old Caucasian woman today, the risk of a hip fracture over her remaining life-time is about 17%.

Through diagnostic bone mass measurements at the hip and assessment of biochemical parameters, a great deal has been learned in recent years about reduction of hip fracture risk. Preventive strategies are based on prevention of falls, use of hip protectors, and prevention of bone fragility. The latter includes the optimization of peak bone mass during childhood, postmenopausal estrogen replacement therapy, and also late prevention consisting in reversing senile secondary hyperparathyroidism, which plays an important role in the decrease of skeletal strength. This secondary hyperparathyroidism, which results from both vitamin D insufficiency and low calcium intake, is preventable with vitamin D3 and calcium supplements.

This study tries to define the types of patients, both at risk of osteoporosis and with established disease, who may benefit from calcium and vitamin D supplementation. The importance of adequate compliance in these individuals is also discussed. Calcium and vitamin D therapy has been recommended for older persons, either frail and institutionalized or independent, with key risk factors including decreased bone mineral density (BMD), osteoporotic fractures, increased bone remodelling as a result of secondary hyperparathyroidism and increased propensity to falls. In addition, treatment of osteoporosis with a bisphosphonate was less effective in patients with vitamin D deficiency. Calcium and vitamin D supplementation is a key component of prevention and treatment of osteoporosis unless calcium intake and vitamin D status are optimal. For primary disease prevention, supplementation should be targeted to those with dietary insufficiencies. Several serum 25-hydroxyvitamin D (25(OH)D) cut-offs have been proposed to define vitamin D insufficiency (as opposed to adequate vitamin D status), ranging from 30 to 100 nmol/l. Based on the relationship between serum 25(OH)D, BMD, bone turnover, lower extremity function and falls, we suggest that 50 nmol/l is the appropriate serum 25(OH)D threshold to define vitamin D insufficiency. Supplementation should therefore generally aim to increase 25(OH)D levels within the 50-75 nmol/l range. This level can be achieved with a dose of 800 IU/day vitamin D, the dose that was used in successful fracture prevention studies to date; a randomized clinical trial assessing whether higher vitamin D doses achieve a greater reduction of fracture incidence would be of considerable interest. As calcium balance is not only affected by vitamin D status but also by calcium intake, recommendations for adequate calcium intake should also be met. The findings of community-based clinical trials with vitamin D and calcium supplementation in which compliance was moderate or less have often been negative, whereas studies in institutionalized patients in whom medication administration was supervised ensuring adequate compliance demonstrated significant benefits." }, { "id": "pubmed23n0396_7604", "title": "Combined calcium and vitamin D3 supplementation in elderly women: confirmation of reversal of secondary hyperparathyroidism and hip fracture risk: the Decalyos II study.", "score": 0.0162569649295313, "content": "Vitamin D insufficiency and low calcium intake contribute to increase parathyroid function and bone fragility in elderly people. Calcium and vitamin D supplements can reverse secondary hyperparathyroidism thus preventing hip fractures, as proved by Decalyos I. Decalyos II is a 2-year, multicenter, randomized, double-masked, placebo-controlled confirmatory study. The intention-to-treat population consisted of 583 ambulatory institutionalized women (mean age 85.2 years, SD = 7.1) randomized to the calcium-vitamin D3 fixed combination group (n = 199); the calcium plus vitamin D3 separate combination group (n = 190) and the placebo group (n = 194). Fixed and separate combination groups received the same daily amount of calcium (1200 mg) and vitamin D3 (800 IU), which had similar pharmacodynamic effects. Both types of calcium-vitamin D3 regimens increased serum 25-hydroxyvitamin D and decreased serum intact parathyroid hormone to a similar extent, with levels returning within the normal range after 6 months. In a subgroup of 114 patients, femoral neck bone mineral density (BMD) decreased in the placebo group (mean = -2.36% per year, SD = 4.92), while remaining unchanged in women treated with calcium-vitamin D3 (mean = 0.29% per year, SD = 8.63). The difference between the two groups was 2.65% (95% CI = -0.44, 5.75%) with a trend in favor of the active treatment group.

The relative risk (RR) of HF in the placebo group compared with the active treatment group was 1.69 (95% CI = 0.96, 3.0), which is similar to that found in Decalyos I (RR = 1.7; 95% CI = 1.0, 2.8).

Trials that administered 400 IU vitamin D did not achieve fracture efficacy. Notably, there was a significant association between higher achieved 25-hydroxyvitamin D levels (25(OH)D) in the treatment groups and fracture efficacy: The minimal mean level where fracture efficacy was observed was 74 nmol/l (25(OH)D). Epidemiological data for bone density and lower extremity strength support this threshold, and high-quality trials that used 700 to 800 IU D3 suggested fall risk reduction by 35 to 65% in institutionalized and community-dwelling older individuals. However, since the 2005 meta-analysis, benefits of vitamin D on fracture and fall reduction have been questioned by results from several recent trials. This review proposes that the interpretation of these recent trials is hindered by different doses of vitamin D, different types of supplemental vitamin D (D3 or ergocalciferol D2), low adherence, concurrent use of supplements outside the study protocol, open study design, short follow-up, and/or different patient risk profiles including primary and secondary fracture prevention. In most recent trials, low adherence, the use of the relatively less potent D2, or a too low dose of D3 (400 IU) may have prohibited a shift of (25(OH)D) levels in the treatment groups to the desirable range of at least 75 nmol/l. In summary, from recent trials, two lesson may be learned: (1) Adherence less than 60% is insufficient to achieve fracture efficacy with daily 800 IU D3 plus calcium, (2) D2 in any application or any previously studied dose may not reduce fractures in institutionalized or community-dwelling older individuals." }, { "id": "pubmed23n0667_6165", "title": "Treatment for osteoporosis in Australian residential aged care facilities: consensus recommendations for fracture prevention.", "score": 0.015027612574341546, "content": "Older people living in residential aged care facilities (RACFs) are at considerably higher risk of suffering fractures than older people living in the community.

Opinion is divided about the value of routine measurements of serum concentrations of 25-hydroxyvitamin D, parathyroid hormone and bone turnover markers. The non-pharmacological approach to fracture prevention includes multifactorial programs of falls prevention and the use of hip protectors. Vitamin D supplementation is recommended for all patients in RACFs. Dietary calcium intake should be optimised (1200-1500 mg per day is recommended) and supplementation offered to those with inadequate intake.

The efficacy of treatment will depend on the efficiency and level of implementation of clinical case finding to select patients at risk, the results of additional investigations, the efficacy, tolerance and safety of medical intervention and the adherence to treatment during follow-up. Each of these steps is critical in treatment in daily practice. Failure to consider one or another step can result in suboptimal fracture prevention or overtreatment. The aim of case finding is to identify patients for treatment, who have disease characteristics of patients in whom fracture prevention has been demonstrated in randomised controlled trials (RCTs). These include patients with a low-trauma hip or vertebral fracture, with a low bone mineral density (BMD) or with a high risk of fracture based on the presence of clinical risk factors (CRFs) for osteoporosis and fractures such as included in the FRAX case-finding algorithm, with or without BMD. Case finding starts clinically, with systematic or opportunistic doctor- and/or patient-driven evaluation for the presence of CRFs, but its implementation is low. Further investigations aim to assess the risk of fracture(s) and to have baseline measurements for the subsequent monitoring of treatment, to exclude diseases that mimic osteoporosis, to identify the cause of osteoporosis and contributory factors and to select the most appropriate treatment.

This article presents the rationale for calcium and vitamin D supplementation in the prevention and treatment of osteoporotic fractures and reviews the literature evidence on the efficacy of this strategy. Two musculoskeletal risk factors are implicated in osteoporotic fractures in the elderly: the loss of bone mass due to secondary hyperparathyroidism and the increased propensity to falls. Calcium and vitamin D reverse secondary hyperparathyroidism with resultant beneficial effects on bone mineral density (BMD). Additionally, calcium and vitamin D supplementation significantly improves body sway and lower extremity strength, reducing the risk of falls. The effects of combined calcium and vitamin D on parathyroid function and BMD provide a strong rationale for the use of this therapy in the prevention and treatment of osteoporosis and osteoporotic fractures. There is general agreement that, in patients with documented osteoporosis, calcium and vitamin D supplementation should be an integral component of the management strategy, along with antiresorptive or anabolic treatment. Frail elderly individuals constitute another major target population for calcium and vitamin D because evidence from randomized studies in institutionalized elderly subjects demonstrates that these supplements reduce osteoporotic fracture risk, particularly in the presence of dietary deficiencies. However, the results of trials in community-dwelling subjects have been equivocal. Within the primary-care setting, further research is required to establish appropriate target subgroups for calcium and vitamin D supplementation; overall, the data are consistent with a benefit individuals with insufficient calcium and/or vitamin D, although patients with documented osteoporosis will derive further benefit in terms of fracture prevention from the addition of an antiresorptive agent." }, { "id": "pubmed23n0913_22610", "title": "The use of cholecalciferol in patients with hip fracture.", "score": 0.013636363636363637, "content": "Major osteoporotic fractures are steadily increasing due to population aging.

Aim of this study was to assess the trends in the use of vitamin D supplements containing cholecalciferol in the population of hip fracture patients older than 65 years, resident in the region of Tuscany (Italy) in the years 2011-2015 and to describe vitamin D status in a subgroup of this individuals directly referred to a bone clinic for further evaluation after hip osteoporotic fracture. Data were retrieved from the electronic anonymous regional administrative database administered by the Region of Tuscany (Italy) in the years 2011-2015 within the T.A.R.Ge.T. project (Trattamento Appropriato delle Rifratture Geriatriche in Toscana, i.e., \"Appropriate treatment of geriatric refractures in Tuscany\"), a program endorsed by the region itself. Data pertaining to cholecalciferol prescriptions and hospital discharge codes were retrieved and appropriately crossed to get data on the use of cholecalciferol supplements in patients before and after a hip fracture. A retrospective analysis was carried out in a subgroup of subjects (n 254) appropriately referred to the local fracture liaison service after the major osteoporotic fracture and vitamin D status in terms of serum 25(OH) vitamin D levels was assessed. The majority of subjects experiencing a hip fracture (98.2% and 88.3% in 2011 and 2015, respectively) did not receive vitamin D supplements at the time of the fracture event. Although a trend in increase in prescriptions for cholecalciferol supplements could be observed in the years of the study, the percentage of treated individuals remained low even after the fracture, since only 30-35% of subjects receives cholecalciferol supplements at one year after the fracture. Cholecalciferol remained the most prescribed drug in this population, while a substantial decrease of cholecalciferol in association with calcium salts was observed. The use of high doses of cholecalciferol has decreased in this population, while diminished the use of the drops has been accompanied by an increase in prescriptions of single monthly dose supplements. The correction of vitamin D inadequacy is preliminary to any treatment for osteoporosis and together with calcium may reduce fracture risk by itself. The prescription of vitamin D supplements is low in patients before and after a hip fracture in a Mediterranean region and despite the overall increase in vitamin use and abuse in the general population. Proper educational programs and active fracture liaison services are needed in order to bridge this gap." }, { "id": "pubmed23n0575_244", "title": "Use of calcium or calcium in combination with vitamin D supplementation to prevent fractures and bone loss in people aged 50 years and older: a meta-analysis.", "score": 0.01355110475282149, "content": "Whether calcium supplementation can reduce osteoporotic fractures is uncertain.

Consequently, the global prevalence of osteoporotic fractures will increase with the aging of the population. In old age, osteoporosis is associated with a substantial burden in terms of morbidity and mortality. Nevertheless, osteoporosis in old age continues to be underdiagnosed and undertreated. This may, at least partly, be explained by the fact that evidence of the antifracture efficacy of osteoporosis treatments comes mainly from randomized controlled trials in postmenopausal women with a mean age of 70-75 years. However, in the last years, subgroup analyses of these landmark trials have been published investigating the efficacy and safety of osteoporosis treatment in the very elderly. Based on this evidence, this narrative review discusses the pharmacological management of osteoporosis in the oldest old (≥80 years). Because of the high prevalence of calcium and/or vitamin D deficiency in old age, these supplements are essential in the management of osteoporosis in the elderly people. Adding antiresorptive or anabolic treatments or combinations, thereof, reduces the risk of vertebral fractures even more, at least in the elderly with documented osteoporosis. The reduction of hip fracture risk by antiresorptive treatments is less convincing, which may be explained by insufficient statistical power in some subanalyses and/or a higher impact of nonskeletal risk factors in the occurrence of hip fractures. Compared with younger individuals, a larger absolute risk reduction is observed in the elderly because of the higher baseline fracture risk. Therefore, the elderly will benefit more of treatment. In addition, current osteoporosis therapies also appear to be safe in the elderly.

Drugs that inhibit bone resorption constitute the mainstay for the treatment of postmenopausal osteoporosis. A recent meta-analysis indicates that vitamin D can reduce the risk of hip fractures only if calcium supplements are also administered. The effect of hormone replacement therapy on the risk of non vertebral fractures is less clear than on vertebral fractures. Raloxifene (a SERM) reduces the rate of vertebral fractures and of breast cancer, but it does not protect against hip fracture. Bisphosphonates are the most commonly used compounds to treat postmenopausal osteoporosis. The level of evidence for currently used bisphosphonates (alendronate, ibandronate, risedronate, zoledronate) to reduce vertebral fracture rate is maximal. Results of controlled clinical trials indicate a reduction in the risk of vertebral fractures of 40-50% and of 20-40% for non vertebral fractures, including hip fractures. However, their relative efficacy on hip fractures has been less well studied and remains more controversial. Long-term compliance of bisphosphonate therapy is improved by intermittent schemes. The most recent developpements concern the intravenous administration of ibandronate and even more of zoledronate (yearly infusions). The reduction in the rate of vertebral and hip fractures has been demonstrated in the main zoledronate trial and a prolongation of survival has been shown in the study including patients with a recent hip fracture.

Painful diabetic polyneuropathy.", "score": 0.016560678325384208, "content": "In the industrialized world, polyneuropathy induced by diabetes mellitus (DM) is one of the most prevalent forms of neuropathy. Diabetic neuropathy can result from a direct toxic effect of glucose on nerve cells. Additionally, the damage of the nerve structures (central and peripheral) is accompanied by a microvascular dysfunction, which damages the vasa nervorum. More than 80% of the patients with DM-induced polyneuropathy have a distal and symmetric presentation. The initial symptoms are: signs of diminished sensation, burning feet, which may occur particularly during the night and worsen when touched, and tingling sensation in the feet. Attacks of shooting pain may also occur. Proper control of DM is mandatory. Based on the recently published National Institute for Health and Clinical Excellence guidelines, treatment of painful diabetic neuropathy should start with duloxetine or amitriptyline if duloxetine is contraindicated. If pain relief is inadequate, monotherapy with amitriptyline or pregabalin, or combination therapy with amitriptyline and pregabalin should be considered. If pain relief is still insufficient, tramadol instead of or in combination with a second-line agent should be considered. In patients who are unable to take oral medication, topical lidocaine can be considered for localized pain. There are currently four studies showing that spinal cord stimulation can potentially provide pain alleviation for the longer term in patients with painful diabetic polyneuropathy. Complications are mainly implant related, though infections also occur. The available evidence (2 C+) justifies spinal cord stimulation to be considered, preferably study related." }, { "id": "pubmed23n0702_7029", "title": "Painful diabetic neuropathy: diagnosis and management.", "score": 0.014608952287260207, "content": "The prevalence of painful diabetic peripheral neuropathy (PDN) is about 20% in patients with type 2 diabetes and 5% in those with type 1. Patients should be systematically questioned concerning suggestive symptoms, as they are not usually volunteers. As PDN is due to small-fibre injury, the 10 g monofilament pressure test as well as the standard electrophysiological procedures may be normal. Diagnosis is based on clinical findings: type of pain (burning discomfort, electric shock-like sensation, aching coldness in the lower limbs); time of occurrence (mostly at rest and at night); and abnormal sensations (such as tingling or numbness). The DN4 questionnaire is an easy-to-use validated diagnostic tool. Three classes of drugs are of equal value in treating PDN: tricyclic antidepressants; anticonvulsants; and selective serotonin-reuptake inhibitors. These compounds may be prescribed as first-line therapy following pain assessment using a visual analogue scale. If the initial drug at its maximum tolerated dose does not lead to a decrease in pain of at least 30%, another drug class should be prescribed; if the pain is decreased by 30% but remains greater than 3/10, a drug from a different class may be given in association." }, { "id": "wiki20220301en023_25278", "title": "Peripheral neuropathy", "score": 0.012192048390145548, "content": "Most types of polyneuropathy progress fairly slowly, over months or years, but rapidly progressive polyneuropathy also occurs.

Sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists prevent adverse cardiovascular and renal outcomes in patients with type 2 diabetes mellitus and also reduce all-cause and cardiovascular mortality. Most older adults (mean age, 75 years) with prediabetes do not progress to diabetes. Among patients in this age group with type 2 diabetes treated with medication, an A1C level of less than 7% is associated with increased risk of hospitalization for hypoglycemia, especially when using a sulfonylurea or insulin. For patients with chronic low back pain, exercise, nonsteroidal anti-inflammatory drugs, duloxetine, and opioids were shown to be more effective than control in achieving a 30% reduction in pain, but self-discontinuation of duloxetine and opioids was common. There is no clinically important difference between muscle relaxants and placebo in the treatment of nonspecific low back pain. In patients with chronic pain, low- to moderate-quality evidence supports exercise, yoga, massage, and mindfulness-based stress reduction. For acute musculoskeletal pain, acetaminophen, 1,000 mg, plus ibuprofen, 400 mg, without an opioid is a good option. Regarding screening for colorectal cancer, trial evidence supports performing fecal immunochemical testing every other year. For chronic constipation, evidence supports polyethylene glycol, senna, fiber supplements, magnesium-based products, and fruit-based products. The following abdominal symptoms carry a greater than 3% risk of cancer or inflammatory bowel disease: dysphagia or change in bowel habits in men; rectal bleeding in women; and abdominal pain, change in bowel habits, or dyspepsia in men and women older than 60 years. For secondary prevention in those with established arteriosclerotic cardiovascular disease, 81 mg of aspirin daily appears to be effective. The Framingham Risk Score and the Pooled Cohort Equations both overestimate the risk of cardiovascular events. Over 12 years, no association between egg consumption and cardiovascular events was demonstrated. Gabapentin, pregabalin, duloxetine, and venlafaxine provide clinically meaningful improvements in chronic neuropathic pain. In patients with moderate to severe depression, initial titration above the minimum starting dose of antidepressants in the first eight weeks of treatment is not more likely to increase response. In adults with iron deficiency anemia, adding vitamin C to oral iron has no effect. In children with pharyngitis, rhinosinusitis, acute bronchitis, or acute otitis media, providing education combined with a take-and-hold antibiotic prescription results in 1 in 4 of those children eventually taking an antibiotic." }, { "id": "pubmed23n0998_22168", "title": "A comparative double-blind randomized study on the effectiveness of Duloxetine and Gabapentin on painful diabetic peripheral polyneuropathy.", "score": 0.010560044580663137, "content": "<bBackground:</b The most common cause of polyneuropathy is diabetes mellitus.

Totally, 104 painful diabetic peripheral polyneuropathy (PDPP) patients who had a minimum Visual Analog Scale (VAS) of 40 millimeters, received no pain-controlling medication, and had no other severe disease at its final stage were randomly assigned to two groups (n=52) through the four block method.

Members of the Canadian Medical Association identified 20 of these POEMs as most relevant to practice. This article reviews the clinical questions and bottom-line answers from these studies. Blood pressure should be measured after a period of rest, using a bare arm, and orthostatic blood pressure is more predictive when measured after one minute of standing rather than three minutes. Intensive blood pressure lowering results in cardiovascular benefits but also renal harms in high-risk patients with an average age of 68 years. The initiation of a statin for primary prevention does not reduce cardiovascular events in adults 65 years or older. Sterile gloves do not reduce the risk of infection for common outpatient skin procedures, and the preferred approach to managing onychomycosis is empiric oral terbinafine. Routine home glucose monitoring is not needed in patients with type 2 diabetes mellitus, and trying to achieve an A1C target level of 6.0% rather than 7.0% to 7.9% does not improve outcomes and may be harmful. Fasting blood glucose and A1C levels have limited accuracy for identifying glucose intolerance, and patients 65 years and older with thyroid-stimulating hormone levels between 4.6 and 10.0 mIU per mL should be rechecked before considering treatment. Gabapentin and pregabalin are not effective for acute or chronic low back pain, even in patients with sciatica. Physical therapy does not provide any additional benefit over usual care in patients with acute ankle sprain, and corticosteroid injections for knee osteoarthritis are ineffective and may damage cartilage. A two-question screening test can rule out depression in older adults; a large U.S. trial continued to find no benefit to prostate cancer screening; and clinicians need to be thoughtful about how they discuss recommendations to stop screening for cancer in older patients. Finally, ibuprofen, naproxen, and celecoxib have similar risks of adverse events, and continuous positive airway pressure in patients with obstructive sleep apnea does not reduce the risk of cardiovascular events." }, { "id": "InternalMed_Harrison_15296", "title": "InternalMed_Harrison", "score": 0.0098467067625055, "content": "evidence of peripheral nerve disease.

She lives with her husband and enjoys gardening and reading. She has two grown children and three grandchildren who live approximately 180 miles away. SECOND CANCER DIAGNOSIS  One morning while showering, Sarah detected a painless quarter-sized lump on her inner thigh. While she thought it was unusual, she felt it would probably go away. One month later, she felt the lump again; she thought that it had grown, so she scheduled a visit with her primary care physician. A CT scan revealed a 6.2-cm soft-tissue mass in the left groin. She was referred to an oncologic surgeon and underwent an excision of the groin mass. Pathology revealed a grade 3 malignant melanoma. She was later tested and found to have BRAF-negative status. Following her recovery from surgery, Sarah was further evaluated with an MRI scan of the brain, which was negative, and a PET scan, which revealed two nodules in the left lung. As Sarah had attended a cancer support group during her breast cancer treatment in the past, she decided to go back to the group when she learned of her melanoma diagnosis. While the treatment options for her lung lesions included interleukin-2, ipilimumab (Yervoy), temozolomide, dacarbazine, a clinical trial, or radiosurgery, Sarah's oncologist felt that ipilimumab or radiosurgery would be the best course of action. She shared with her support group that she was ambivalent about this decision, as she had experienced profound fatigue and nausea with chemotherapy during her past treatment for breast cancer. She eventually opted to undergo stereotactic radiosurgery. DISEASE RECURRENCE  After the radiosurgery, Sarah was followed every 2 months. She complained of shortness of breath about 2 weeks prior to each follow-up visit. Each time her chest x-ray was normal, and she eventually believed that her breathlessness was anxiety-related. Unfortunately, Sarah's 1-year follow-up exam revealed a 2 cm × 3 cm mass in her left lung, for which she had a surgical wedge resection. Her complaints of shortness of breath increased following the surgery and occurred most often with anxiety, heat, and gardening activities, especially when she needed to bend over. Sarah also complained of a burning \"pins and needles\" sensation at the surgical chest wall site that was bothersome and would wake her up at night. Sarah met with the nurse practitioner in the symptom management clinic to discuss her concerns. Upon physical examination, observable signs of breathlessness were lacking, and oxygen saturation remained stable at 94%, but Sarah rated her breathlessness as 7 on the 0 to 10 Borg scale. The nurse practitioner prescribed duloxetine to help manage the surgical site neuropathic pain and to assist with anxiety, which in turn could possibly improve Sarah's breathlessness. Several nonpharmacologic modalities for breathlessness were also recommended: using a fan directed toward her face, working in the garden in the early morning when the weather is cooler, gardening in containers that are at eye level to avoid the need to bend down, and performing relaxation exercises with pursed lip breathing to relieve anxiety-provoked breathlessness. One month later, Sarah reported relief of her anxiety; she stated that the fan directed toward her face helped most when she started to feel \"air hungry.\" She rated her breathlessness at 4/10 on the Borg scale. SECOND RECURRENCE: MULTIPLE PULMONARY NODULES  Sarah's chest x-rays remained clear for 6 months, but she developed a chronic cough shortly before the 9-month exam. An x-ray revealed several bilateral lung lesions and growth in the area of the previously resected lung nodule. Systemic therapy was recommended, and she underwent two cycles of ipilimumab. Sarah's cough and breathlessness worsened, she developed colitis, and she decided to stop therapy after the third cycle. In addition, her coughing spells triggered bronchospasms that resulted in severe anxiety, panic attacks, and air hunger. She rated her breathlessness at 10/10 on the Borg scale during these episodes. She found communication difficult due to the cough and began to isolate herself. She continued to attend the support group weekly but had difficulty participating in conversation due to her cough. Sarah was seen in the symptom management clinic every 2 weeks or more often as needed. No acute distress was present at the beginning of each visit, but when Sarah began to talk about her symptoms and fear of dying, her shortness of breath and anxiety increased. The symptom management nurse practitioner treated the suspected underlying cause of the breathlessness and prescribed oral lorazepam (0.5 to 1 mg every 6 hours) for anxiety and codeine cough syrup for the cough. Opioids were initiated for chest wall pain and to control the breathlessness. Controlled-release oxycodone was started at 10 mg every 12 hours with a breakthrough pain (BTP) dose of 5 mg every 2 hours as needed for breathlessness or pain. Sarah noted improvement in her symptoms and reported a Borg scale rating of 5/10. Oxygen therapy was attempted, but subjective improvement in Sarah's breathlessness was lacking. END OF LIFE  Sarah's disease progressed to the liver, and she began experiencing more notable signs of breathlessness: nasal flaring, tachycardia, and restlessness. Opioid doses were titrated over the course of 3 months to oxycodone (40 mg every 12 hours) with a BTP dose of 10 to 15 mg every 2 hours as needed, but her breathlessness caused significant distress, which she rated 8/10. The oxycodone was rotated to IV morphine continuous infusion with patient-controlled analgesia (PCA) that was delivered through her implantable port. This combination allowed Sarah to depress the PCA as needed and achieve immediate control of her dyspneic episodes. Oral lorazepam was also continued as needed. Sarah's daughter moved home to take care of her mother, and hospice became involved for end-of-life care. As Sarah became less responsive, nurses maintained doses of morphine for control of pain and breathlessness and used a respiratory distress observation scale to assess for breathlessness since Sarah could no longer self-report. A bolus PCA dose of morphine was administered by Sarah's daughter if her mother appeared to be in distress. Sarah died peacefully in her home without signs of distress.

It affects approximately half of patients with diabetes. DPN is symmetric and predominantly sensory, starting distally and gradually spreading proximally in a glove-and-stocking distribution. It causes substantial morbidity and is associated with increased mortality. The unrelenting nature of pain in this condition can negatively affect a patient's sleep, mood, and functionality and result in a poor quality of life. The purpose of this review was to critically review the current literature on the diagnosis and treatment of DPN, with a focus on the treatment of neuropathic pain in DPN. A comprehensive literature review was undertaken, incorporating article searches in electronic databases (EMBASE, PubMed, OVID) and reference lists of relevant articles with the authors' expertise in DPN. This review considers seminal and novel research in epidemiology; diagnosis, especially in relation to novel surrogate end points; and the treatment of neuropathic pain in DPN. We also consider potential new pharmacotherapies for painful DPN. DPN is often misdiagnosed and inadequately treated. Other than improving glycemic control, there is no licensed pathogenetic treatment for diabetic neuropathy. Management of painful DPN remains challenging due to difficulties in personalizing therapy and ascertaining the best dosing strategy, choice of initial pharmacotherapy, consideration of combination therapy, and deciding on defining treatment for poor analgesic responders. Duloxetine and pregabalin remain first-line therapy for neuropathic pain in DPN in all 5 of the major published guidelines by the American Association of Clinical Endocrinologists, American Academy of Neurology, European Federation of Neurological Societies, National Institute of Clinical Excellence (United Kingdom), and the American Diabetes Association, and their use has been approved by the US Food and Drug Administration.

Background Abnormal sensation, such as numbness or tingling, is traditionally thought to originate from neural compression. There is limited evidence to support reports of abnormal sensation arising from a trigger point. Case Description The patient was a 60-year-old woman with a primary complaint of right shoulder pain and secondary complaints of neck pain and right upper extremity numbness. Cervical spine neurological examination was unremarkable, and manual examination did not reproduce the patient's arm numbness or tingling symptoms. Compression of a trigger point in the infraspinatus and teres minor reproduced the patient's primary complaint of shoulder pain. The initial intervention included dry needling, which reproduced her upper extremity numbness. Subsequent treatment included manual therapy and exercise. Outcomes The patient was seen for a total of 3 visits, including the evaluation. Dry needling was utilized in 2 of her 3 visits. At discharge, she reported complete resolution of pain and altered sensation. Additionally, her scores on the Neck Disability Index, numeric pain-rating scale, and global rating of change exceeded the minimal clinically important difference. These outcomes were maintained at 2- and 12-month follow-up phone calls. Discussion This case report described the examination and use of dry needling in a case where the diagnosis was unclear.

We report the results obtained with long-term (3-4 years) carvedilol administration to 40 patients with idiopathic dilated cardiomyopathy who were initially recruited in a 4-month double-blind placebo-controlled trial. In the initial 4-month double-blind trial, 20 patients were randomized to placebo and 20 to carvedilol treatment. All patients, except one who was not on ACE-inhibitors, were on digoxin, furosemide and ACE-inhibitors. Carvedilol or placebo doses were progressively titrated, at weekly intervals, up to the maximal doses of 25 mg bid. After the initial 4-month double-blind phase, all patients were followed long term. Mean follow-up duration was 52 +/- 12 months (range 48-61). Among the 20 patients initially randomized to carvedilol administration, 4 died (3 for cardiac and 1 for extracardiac causes) and 2 underwent heart transplant. Among the 20 patients initially randomized to placebo, 5 died for cardiac causes, 3 underwent heart transplant and 4 were started on carvedilol because of progressive heart failure during the initial 4 months of the study. The remaining 8 patients, who were kept on digoxin, furosemide and ACE-inhibitors, were used as control group. Each patient underwent an assessment of clinical conditions (NYHA functional classification and Minnesota Living with Heart Failure questionnaire), equilibrium radionuclide ventriculography, and maximal cardiopulmonary bicycle exercise testing. Exams were performed before treatment, after 4 and 12 months, and at the end of the follow-up period. No significant difference between the carvedilol and control group was present at baseline.

Long term rapid atrial arrhythmia can lead to further deterioration of cardiac function. This case is a 51-year-old male. He was admitted to Department of Cardiology, Peking University Third Hospital with palpitation and fatigue after exercise. Electrocardiogram showed incessant atrial tachycardia. Echocardiography revealed dilation of all his four chambers, especially the right ventricle, with the left ventricular ejection fraction of 40% and the right ventricular hypokinesis. Cardiac magnetic resonance imaging found that the right ventricle was significantly enlarged, and the right ventricular aneurysm had formed; the right ventricular ejection fraction was as low as 8%, and the left ventricular ejection fraction was 35%. The patients met the diagnostic criteria of ARVC, and both left and right ventricles were involved.

The therapeutic approaches to heart failure have undergone considerable changes during the last few years. The guidelines have to be updated almost yearly due to new results from prospective randomized studies. Although an agreement could be reached with respect to general measures and drug treatment, no agreement on mechanical devices, pacemakers and surgical interventions has been reached. The basis for medical treatment of chronic heart failure depends on diuretics, digitalis, ACE inhibitors, and beta-blockers. Calcium antagonists and other positive inotropic drugs, other than digitalis, should be avoided as far as possible. Thiazides, loop diuretics and aldosterone antagonists are needed for acute and chronic treatment of heart failure, alone or in combination (diuretic resistant heart failure!). Digitalis glycosides are needed in patients with atrial fibrillation with a fast ventricular rate or atrial flutter and in patients with systolic dysfunction, large hearts and symptomatic failure class NYHA III and IV. However, digitalis does not convert atrial fibrillation to sinus rhythm. Today there is no question that ACE inhibitors improve the prognosis of all patients with heart failure in all stages, if ejection fraction is reduced. Therefore, most patients after myocardial infarction or after having experienced pump failure due to myocarditis or cardiomyopathy are treated with ACE inhibitors and diuretics. The beneficial effects of ACE inhibitors seem to be most pronounced the worse the situation is. Relative risk reductions (mortality!) between 10% and 40% have been published depending on the severity of symptomatic left ventricular dysfunction. Those patients with high absolute risk have more to gain than those with low risk for any given \"risk reduction\", of course. Recent studies also indicate that most high risk cardiac patients profit from ACE inhibitors even if pump function is normal (i.e., patients with coronary heart disease, diabetes mellitus, cerebral vascular disease, hypertension) (15). AT1 antagonists can substitute for ACE inhibitors, if the latter are not tolerated due to cough. Up to now, beta-blocking agents apart from diuretics seem to be the best investigated drugs in heart failure. Large controlled studies with bisoprolol, carvedilol and metoprolol in addition to diuretics, digitalis and ACE inhibitors convincingly yielded positive results in chronic left ventricular failure patients. Reduction of mortality by 35% and even of sudden cardiac deaths by 40% have been proven beyond doubt. Thus, heart failure patients today should also receive beta-blocking agents in all stages of the disease. In the era of controlled prospective studies (evidence-based medicine), physicians are well advised to use only drugs that have been proven beneficial in large controlled studies." }, { "id": "pubmed23n0505_21749", "title": "Effects of carvedilol on ventriculo-arterial coupling in patients with heart failure.", "score": 0.012828947368421053, "content": "Ventriculo-arterial coupling, defined as the ratio of the effective afterload (Ea) to contractility (Ees), reflects the mechano-energetic performance of the heart and is increased in chronic heart failure (CHF); the aim of treatment is to reduce its value. We studied the effect of carvedilol on the Ea/Ees ratio in patients with CHF treated with ACE-inhibitors, diuretics, and digoxin. Between November 1999 and October 2001, 36 consecutive ambulatory patients (aged 31 to 76 years) with stable CHF and idiopathic or hypertensive cardiomyopathy, in sinus rhythm and with a left ventricular ejection fraction &lt; or = 40%, were started on carvedilol and the dose was increased to the maximum tolerated. Ees was calculated as the left ventricular systolic pressure--taken as the systolic arterial pressure measured using the cuff manometer simultaneously with two-dimensional echocardiographic recordings--divided by the left ventricular end-systolic volume. Ea was measured as the ratio of the left ventricular systolic pressure to the stroke volume. All patients were investigated prospectively after 6 and 12 months of treatment. Out of 36 patients, 4 did not tolerate the drug and were dropped out. At 6.35 +/- 1 months, the daily dosage of carvedilol was 49.7 +/- 21 mg.

Moreover, the Ea reduction was related linearly to the decrease in heart rate (r = 0.46, p = 0.001). There was no change in diuretic or ACE-inhibitor dosing during carvedilol titration. At 14.7 +/- 2 months of follow-up, no further variation occurred, short of a trend toward a slight increase in Ees (1.38 +/- 0.49 to 1.58 +/- 0.65, p = 0.07). Carvedilol, added to the conventional therapy of CHF, improves left ventricular performance and reduces the Ea/Ees ratio by decreasing Ea, mainly through a reduction in heart rate.

Forty patients with idiopathic dilated cardiomyopathy treated with digoxin, furosemide and angiotensin-converting enzyme inhibitors were randomized in a double-blind manner to receive either placebo or carvedilol. Right heart hemodynamic variables were evaluated up to 8 h after short-term drug administration and, on the next day, during cardiopulmonary exercise testing before and 3 h after drug ingestion. Placebo or carvedilol was added to standard therapy, starting with a dose of 6.25 mg twice a day with weekly increments up to the maximum of 25 mg twice a day. Patients were reevaluated after 4 months by cardiopulmonary exercise testing and measurement of right heart hemodynamic variables 12 h after last drug ingestion and 3 h after drug readministration. Left ventricular ejection fraction and volume, measured by equilibrium radionuclide ventriculography, quality of life and submaximal exercise duration were assessed before and after long-term therapy. Compared with placebo, carvedilol produced a short-term reduction in heart rate and pulmonary artery and pulmonary wedge pressures and, after long-term administration, increased both rest and peak exercise cardiac, stroke volume and stroke work indexes, with a further reduction in right atrial, pulmonary artery and pulmonary wedge pressures. Long-term carvedilol administration also improved rest left ventricular ejection fraction (from 20 +/- 7% to 30 +/- 12%, p &lt; 0.001), submaximal exercise capacity, quality of life and New York Heart Association functional class. No baseline variable was predictive of the response to therapy.

The approach to pharmacologic treatment has become a combined preventive and symptomatic management strategy. Ideally, treatment should be initiated in patients at risk, preventing disease progression. In patients who have progressed to symptomatic left ventricular dysfunction, certain therapies have been demonstrated to improve survival, decrease hospitalizations, and reduce symptoms. The mainstay therapies are angiotensin-converting enzyme (ACE) inhibitors and beta-blockers (bisoprolol, carvedilol, and metoprolol XL/CR), with diuretics to control fluid balance. In patients who cannot tolerate ACE inhibitors because of angioedema or severe cough, valsartan can be substituted. Valsartan should not be added in patients already taking an ACE inhibitor and a beta-blocker. Spironolactone is recommended in patients who have New York Heart Association (NYHA) class III to IV symptoms despite maximal therapies with ACE inhibitors, beta-blockers, diuretics, and digoxin. Low-dose digoxin, yielding a serum concentration &lt;1 ng/mL can be added to improve symptoms and, possibly, mortality.

Atrial fibrillation is associated with a higher incidence of coronary events, stroke, and mortality than sinus rhythm. A fast ventricular rate associated with atrial fibrillation may cause tachycardia-related cardiomyopathy. Management of atrial fibrillation includes treatment of underlying causes and precipitating factors. Immediate direct-current cardioversion should be performed in persons with atrial fibrillation associated with acute myocardial infarction, chest pain due to myocardial ischemia, hypotension, severe heart failure, or syncope. Intravenous beta-blockers, verapamil, or diltiazem may be used to immediately slow a fast ventricular rate associated with atrial fibrillation. An oral beta-blocker, verapamil, or diltiazem should be given to persons with atrial fibrillation if a rapid ventricular rate occurs a rest or during exercise despite digoxin.

Nondrug therapies should be performed in persons with symptomatic atrial fibrillation in whom a rapid ventricular rate cannot be slowed by drug therapy. Paroxysmal atrial fibrillation associated with the tachycardia-bradycardia syndrome should be managed with a permanent pacemaker in combination with drugs. A permanent pacemaker should be implanted in persons with atrial fibrillation in whom symptoms such as dizziness or syncope associated with non-drug-induced ventricular pauses longer than 3 seconds develop. Elective direct-current cardioversion has a higher success rate and a lower incidence of cardiac adverse effects than medical cardioversion in converting atrial fibrillation to sinus rhythm.

The therapy includes two basic questions--anticoagulant or anti-aggregation treatment and the control of rhythm or frequency. The anticoagulant therapy should be introduced in all patients, where contraindications are not present, being necessary before every cardioversion, provided atrial fibrillation lasts more than two days. In patients without any heart disease and with a physiological echocardiogram it is possible to administer only anti-aggregation treatment. Cardioversion (the control of rhythm) is recommended to all symptomatic patients, in other cases and especially in older persons the control of frequency is safer and of more advantage. Electrical cardioversion is more effective that a pharmacological treatment, the sinus rhythm is preferably controlled by dofetilid, ibutilid, propafenon and amiodaron.

His history includes hypertension, well controlled with diet and cognitive deterioration in the last year under study by his neurologist. The emergency cranial CT scan shows a left frontal lobar hematoma without contrast uptake. What is the most probable cause of the hematoma?

On MRI using 0.5 T unit t-1 and t-2 weighted spin echo images of these hematomas also showed the similar chronological changes. The history, these CT and MRI studies suggest that two hematomas of this case occurred almost simultaneously in one cerebral hemisphere.

These hemorrhages may be derived from vessel wall weakness because of Abeta depositions in the wall of the cortical and leptomeningeal arteries. Although vessel ruptures in CAA have been thought to occur in cortical arteries, it was recently demonstrated that the primary hemorrhage occurs in the subarachnoid space, particularly the cerebral sulci, as a result of multiple ruptures of meningeal arteries in some cases of subcortical hematoma caused by CAA. Case patient 1 was a 74-year-old woman who presented with epileptic seizure. A restricted SAH in the right frontal lobe was observed on MRI. Thirty-three days later, left hemiparesis occurred suddenly and a huge subcortical hematoma was observed in the right frontal lobe on CT. The hematoma was removed, and the patient was pathologically diagnosed with amyloid angiopathy. Case patient 2 was a 73-year-old man who presented with epileptic seizure. A restricted SAH in the right frontal lobe was observed on MRI. Twenty days later, left hemiparesis occurred suddenly and a huge subcortical hematoma was observed in the right frontoparietal area on CT. Hematoma removal was performed on both patients, and they were diagnosed pathologically with amyloid angiopathy. We report on the cases of 2 patients with CAA who presented with epileptic seizure and were found to have a restricted subarachnoid hematoma in the cerebral sulcus on MRI before their subcortical hemorrhages occurred. Both cases were diagnosed pathologically. This demonstrated that vessel ruptures in CAA can occur in the subarachnoid space, particularly the cerebral sulci, as a result of ruptures of meningeal arteries.

They investigated the correlations between the underlying causes and the clinicoradiographic features in 29 patients who showed no angiographic vascular abnormalities, in order to elucidate the operative indication for such cases. Patients with ruptured saccular aneurysm or trauma were not included in this study. There were 15 males and 14 females, ranging in age from 7 to 76 years (mean 52.4 years). Histological diagnoses of the surgical specimens were as follows: vascular malformation in nine cases (arteriovenous malformation (AVM) in six and cavernous malformation in three), microaneurysm in 11, cerebral amyloid angiopathy in six, and brain tumor in two; in the remaining case the cause was not verified histologically. The underlying cause was determined in 96.5% of cases. The mean patient age was lowest in the cavernous malformation group (27.0 years), followed by the AVM (45.8 years), microaneurysm (59.8 years), and cerebral amyloid angiopathy (70.0 years) groups. Four patients with vascular malformation (three AVM's and one cavernous malformation) had previous episodes of bleeding at the same site, whereas none of those with microaneurysms or cerebral amyloid angiopathy had such episodes. On computerized tomography (CT) scans, the round to oval hematoma was related to the presence of an AVM or cavernous malformation in contrast to microaneurysms and cerebral amyloid angiopathy. Upon infusion of contrast material, variable enhancement was seen in five (two AVM's and three cavernous malformations) of the nine vascular malformations while no enhancement was noted in any patient with microaneurysm or cerebral amyloid angiopathy at the acute stage. Subarachnoid extension of the hematoma was associated with cerebral amyloid angiopathy significantly more frequently than with AVM's (p less than 0.05) and microaneurysms (p less than 0.01). The results suggest that clinicoradiographic pictures in cases with negative angiography are quite different among the three major pathological categories; namely, vascular malformation (AVM and cavernous malformation), microaneurysm, and cerebral amyloid angiopathy. It is suggested that the underlying etiology of a given lobar intracerebral hemorrhage with negative angiography may be predicted by a combination of patient age, history of previous bleeding at the same site, hematoma shape, and subarachnoid extension of the hematoma on CT scans. Based upon these findings, the authors discuss operative indications for such cases." }, { "id": "pubmed23n0567_21957", "title": "[A case of primary subarachnoid hemorrhage due to cerebral amyloid angiopathy].", "score": 0.017786561264822136, "content": "A 77-year-old man who was suffering from an intracerebral hemorrhage of the left subcortex without hypertension was admitted to our hospital.

An iterative analysis involved listening to and discussing cases to identify emergent patterns of initiation of health behavior talk and advice that followed. Physicians initiated 65% of discussions and used two overarching strategies (1) Structured: a routine to ask about health behavior and (2) Opportunistic: use of a trigger to make a transition to talk about health behavior. Opportunistic strategies identified a greater proportion of patients at risk (50% vs. 34%) and led to a greater rate of advice (100% vs. 75%). Patients initiated one-third of health behavior discussions and were more likely to receive advice if they explicitly indicated readiness to change. Opportunistic strategies show promise for a higher yield of identifying patients at risk and leading to advice.

It increases the risk of sudden infant death syndrome, bacterial meningitis, middle ear infection, asthma, and lower respiratory tract infection. The preoperative assessment of children presenting for procedures under general anesthesia is an opportune moment to screen for exposure to ETS and give information about the risks and cessation support (if applicable). This can be described as a \"teachable moment\"; there is a documented need for this public health education and it aligns with the NHS Long Term Plan, aiming to embed public health information into every consultation a patient or family has with a healthcare practitioner. The period preceding and following surgery is a time when patients or their families are motivated to make a behavioral change. It has been shown that parents who smoke are more likely to attempt smoking cessation if their child has had recent surgery but not to maintain their abstinence; however, we know that subsequent quit attempts increase the likelihood that a smoker will succeed in permanently abstaining so aiming for a quit attempt rather than permanent abstinence is a valid aim. A suggested screening method would be to firstly ask all parents or carers in the preoperative health screening questionnaire about their child's exposure to ETS, accepting this lacks both the sensitivity and specificity of a valid screening tool. This can be augmented by measuring exhaled carbon monoxide in any child who is able to comply with the test; exhaled carbon monoxide has been shown to be a valid screening tool for exposure to ETS in adolescents but not children under 12 years of age, perhaps because smaller children may not be able to cooperate with the test which requires a vital capacity maneuver to provide an adequate endtidal sample. A suggested model for smoking cessation intervention is called Very Brief Advice and comprises three parts: Ask about a child's exposure to ETS with/without exhaled carbon monoxide measurement Advise about the risks to the child's general and perioperative health and the health of the smoker and wider family plus the benefits of smoking cessation Act on the response by referring to local smoking cessation support. Referral to local smoking cessation services should be along established pathways. Thus, recording a household smoking status and referring to local smoking cessation services targets a public health measure with benefits beyond the individual patient and planned anesthetic. There is no evidence in the literature of the effect of environmental exposure to electronic cigarettes (\"vaping\") on a child's perioperative health. Further research is needed to establish if preoperative reduction in or removal from exposure to ETS reduces the risk of respiratory adverse events in the child." }, { "id": "pubmed23n0724_12863", "title": "Promoting smoking cessation.", "score": 0.00980392156862745, "content": "Cigarette smoking causes significant morbidity and mortality in the United States.

Clinical contacts with unmotivated patients should emphasize the rewards and relevance of quitting, as well as the risks of smoking and anticipated barriers to abstinence. These messages should be repeated at every opportunity.

However, the rates at which providers address smoking cessation and the success of that support vary. Strategies can be implemented to improve and increase the delivery of smoking cessation support (e.g. through provider training), and to increase the amount and breadth of support given to people who smoke (e.g. through additional counseling or tailored printed materials). To assess the effectiveness of strategies intended to increase the success of smoking cessation interventions in primary care settings. To assess whether any effect that these interventions have on smoking cessation may be due to increased implementation by healthcare providers. We searched the Cochrane Tobacco Addiction Group's Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and trial registries to 10 September 2020. We included randomized controlled trials (RCTs) and cluster-RCTs (cRCTs) carried out in primary care, including non-pregnant adults. Studies investigated a strategy or strategies to improve the implementation or success of smoking cessation treatment in primary care. These strategies could include interventions designed to increase or enhance the quality of existing support, or smoking cessation interventions offered in addition to standard care (adjunctive interventions). Intervention strategies had to be tested in addition to and in comparison with standard care, or in addition to other active intervention strategies if the effect of an individual strategy could be isolated. Standard care typically incorporates physician-delivered brief behavioral support, and an offer of smoking cessation medication, but differs across studies. Studies had to measure smoking abstinence at six months' follow-up or longer. We followed standard Cochrane methods. Our primary outcome - smoking abstinence - was measured using the most rigorous intention-to-treat definition available. We also extracted outcome data for quit attempts, and the following markers of healthcare provider performance: asking about smoking status; advising on cessation; assessment of participant readiness to quit; assisting with cessation; arranging follow-up for smoking participants. Where more than one study investigated the same strategy or set of strategies, and measured the same outcome, we conducted meta-analyses using Mantel-Haenszel random-effects methods to generate pooled risk ratios (RRs) and 95% confidence intervals (CIs). We included 81 RCTs and cRCTs, involving 112,159 participants. Fourteen were rated at low risk of bias, 44 at high risk, and the remainder at unclear risk. We identified moderate-certainty evidence, limited by inconsistency, that the provision of adjunctive counseling by a health professional other than the physician (RR 1.31, 95% CI 1.10 to 1.55; I<sup2</sup = 44%; 22 studies, 18,150 participants), and provision of cost-free medications (RR 1.36, 95% CI 1.05 to 1.76; I<sup2</sup = 63%; 10 studies,7560 participants) increased smoking quit rates in primary care. There was also moderate-certainty evidence, limited by risk of bias, that the addition of tailored print materials to standard smoking cessation treatment increased the number of people who had successfully stopped smoking at six months' follow-up or more (RR 1.29, 95% CI 1.04 to 1.59; I<sup2</sup = 37%; 6 studies, 15,978 participants). There was no clear evidence that providing participants who smoked with biomedical risk feedback increased their likelihood of quitting (RR 1.07, 95% CI 0.81 to 1.41; I<sup2</sup = 40%; 7 studies, 3491 participants), or that provider smoking cessation training (RR 1.10, 95% CI 0.85 to 1.41; I<sup2</sup = 66%; 7 studies, 13,685 participants) or provider incentives (RR 1.14, 95% CI 0.97 to 1.34; I<sup2</sup = 0%; 2 studies, 2454 participants) increased smoking abstinence rates. However, in assessing the former two strategies we judged the evidence to be of low certainty and in assessing the latter strategies it was of very low certainty. We downgraded the evidence due to imprecision, inconsistency and risk of bias across these comparisons. There was some indication that provider training increased the delivery of smoking cessation support, along with the provision of adjunctive counseling and cost-free medications. However, our secondary outcomes were not measured consistently, and in many cases analyses were subject to substantial statistical heterogeneity, imprecision, or both, making it difficult to draw conclusions. Thirty-four studies investigated multicomponent interventions to improve smoking cessation rates. There was substantial variation in the combinations of strategies tested, and the resulting individual study effect estimates, precluding meta-analyses in most cases. Meta-analyses provided some evidence that adjunctive counseling combined with either cost-free medications or provider training enhanced quit rates when compared with standard care alone. However, analyses were limited by small numbers of events, high statistical heterogeneity, and studies at high risk of bias. Analyses looking at the effects of combining provider training with flow sheets to aid physician decision-making, and with outreach facilitation, found no clear evidence that these combinations increased quit rates; however, analyses were limited by imprecision, and there was some indication that these approaches did improve some forms of provider implementation. There is moderate-certainty evidence that providing adjunctive counseling by an allied health professional, cost-free smoking cessation medications, and tailored printed materials as part of smoking cessation support in primary care can increase the number of people who achieve smoking cessation. There is no clear evidence that providing participants with biomedical risk feedback, or primary care providers with training or incentives to provide smoking cessation support enhance quit rates. However, we rated this evidence as of low or very low certainty, and so conclusions are likely to change as further evidence becomes available. Most of the studies in this review evaluated smoking cessation interventions that had already been extensively tested in the general population. Further studies should assess strategies designed to optimize the delivery of those interventions already known to be effective within the primary care setting. Such studies should be cluster-randomized to account for the implications of implementation in this particular setting. Due to substantial variation between studies in this review, identifying optimal characteristics of multicomponent interventions to improve the delivery of smoking cessation treatment was challenging. Future research could use component network meta-analysis to investigate this further." }, { "id": "pubmed23n0541_2781", "title": "A pilot study on inducement of smoking cessation by a simple 5A (asking, advice, assess, assist, and arrange) approach at outpatient clinics.", "score": 0.009615384615384616, "content": "Asking smokers about their smoking status, followed by advice to quit smoking, assessing the intention to quit, assistance with cessation, and arrange of follow-up (5A) is recommended for induction of smoking cessation.

Given the benefit of smoking cessation, strategies to assist individuals who smoke to quit should be a primary focus in modern HIV care. Tobacco harm reduction focuses on reducing health risk without necessarily requiring abstinence. However, there remains uncertainty about the safety, policy and familiarity of specific approaches, particularly the use of vaporised nicotine products. Evidence suggests that vaporised nicotine products may help smokers stop smoking and are not associated with any serious side-effects. However, there is the need for further safety and efficacy data surrounding interventions to assist quitting in the general population, as well as in PLHIV specifically.

It is a type of gallop rhythm by virtue of having an extra sound; the other gallop rhythm is called S4. The two are quite different, but they may sometimes occur together forming a quadruple gallop. If the heart rate is also very fast (tachycardia), it can become difficult to distinguish between S3 and S4 thus producing a single sound called a summation gallop. S3 is a dull, low-pitched sound best heard with the bell placed over the cardiac apex with the patient lying in the left lateral decubitus position. This heart sound when present in a child or young adult implies the presence of a supple ventricle that can undergo rapid filling. Conversely, when heard in a middle-aged or older adult, an S3 is often a sign of disease, indicating increased ventricular filling due to congestive heart failure or severe mitral or tricuspid regurgitation." }, { "id": "pubmed23n0276_19500", "title": "Cardiac pearls.", "score": 0.015407407407407408, "content": "Most diagnoses of cardiovascular disease are made in the office or at the bedside. For example, in pulsus alternans of the radial pulse, observed when first greeting a patient, alteration of intensity of the second sound and systolic murmur and a ventricular (S3) gallop are clinical pearls--often subtle--that diagnose cardiac decompensation. A faint gallop, ventricular (S3) or atrial (S4), might be overlooked in a patient who has an emphysematous chest and an increase in anteroposterior diameter if one listens over the usual areas of the precordium. However, the gallop might be detected easily by listening over the xiphoid or epigastric area. How do you tell the difference between an S4, a split first sound, and an ejection sound? The S4 is eliminated with pressure on the stethoscope, but pressure does not eliminate the ejection sound or the splitting of S1. The atrial sound (S4) is most frequently found in patients who have coronary heart disease, and it is a constant finding in patients who have hypertension. It does not denote heart failure, as does the S3 (ventricular) gallop. In some patients, both atrial (S4) and ventricular (S3) diastolic gallops may be present. This occurrence is common in patients with cardiac decompensation associated with coronary heart disease, hypertensive heart disease, and dilated cardiomyopathy. When these diastolic filling sounds occur in close proximity, a short rumbling murmur may be heard, which causes confusion of this sound with that of a valvular or congenital lesion. When both sounds occur exactly simultaneously, a single sound results. Often, this sound is louder than either the first or second sound and can be misinterpreted as either a valvular or congenital lesion. This, however, is a summation gallop, which is rare. For the most accurate timing of heart sounds and murmurs, the simple technique called \"inching\" is the best. Keeping the second sound in mind as a reference, the physician moves (inches) the stethoscope from the aortic area to the apex. An extra sound may be noted to occur in systole before the second sound, thereby diagnosing a systolic click. If the sound occurs after the second sound, however, it is an S3 or ventricular diastolic gallop. If a murmur appears before S2, it is a systolic murmur; if it appears after S2, it is a diastolic murmur.

Intracardiac sound and pressure recordings from high fidelity catheter-tipped micromanometers have documented that the precordial murmur is the summation of both the systolic ejection murmur (SEM) arising from the LVOT, as well as the mitral regurgitant murmur recorded from the left atrium. The intensity of the precordial murmur varies directly with the LVOT gradient, which in turn is determined primarily by the contractility and loading conditions of the left ventricle. Reversed splitting of the second heart sound (S2) with paradoxical respiratory movement is a common finding in HCM, and when present, almost always denotes a significant LVOT gradient. It is due to marked lengthening of the left ventricular ejection time secondary to prolongation of the contraction and relaxation phases of left ventricular systole. The presence of a fourth heart sound (S4) is the rule in HCM when normal sinus rhythm is present, and is a reflection of a forceful left atrial contraction into a hypertrophied noncompliant left ventricle. A third heart sound (S3) is also common in HCM, and often the initial vibrations occur before the 0 point of the apexcardiogram (ACG) and continue giving the auscultatory impression of a diastolic rumble. When associated with a loud S1, which is frequently present, the clinical presentation may mimic mitral stenosis. This is particularly true when the patient has chronic atrial fibrillation. Careful attention to evidence of marked left ventricular hypertrophy as well as the typical echocardiographic findings of HCM preclude this diagnosis.

There were two types of \"presystolic murmur\": The first type observed in three of the 18 patients occurred during the accelerated phase of the atrial (A) wave of mitral inflow signals and lasted until the first heart sound. The A wave velocity in mitral inflow signals was high at the onset and peak, and rapidly decreased after the peak.

The A wave velocity in mitral inflow signals was low at the onset, but high at the peak and rapidly decreased after the peak. 3.

The calcification ring ratio (CRR = MRC/MVR X 100) was 50.3% in the MR Group and 69.8% in the MS Group.

The study of 122 cases with MRC length greater than or equal to 5 mm suggested that MRC occurred first in the middle scallop of the posterior mitral leaflet, and extended to the posterior scallop, subsequently extending up to the anterior scallop, and finally involved the anterior mitral leaflet beyond the commissures.(ABSTRACT TRUNCATED AT 400 WORDS)" }, { "id": "First_Aid_Step2_9", "title": "First_Aid_Step2", "score": 0.013064516129032259, "content": "Systolic murmurs: Aortic stenosis: Harsh systolic ejection murmur; radiation to carotids.

This systolic murmur is characterised by its exceptional intensity, its raspy character at the base, becoming softer at the apex and in the axilla, the presence of a thrill and irradiation into the neck in 50 to 75% of cases. The etiological diagnosis was ensured precisely by 1) pharmaco-dynamic tests: amyl nitrite accentuates the systolic ejection murmurs and attenuates murmurs due to mitral regurgitation. 2) careful analysis of diastole: a systolic murmur extending into early diastole, a third sound or an opening snap and a low-pitched diastolic murmur, suggest mitral incompetence. A high-pitched diastolic murmur is in favour of aortic stenosis. 3) the carotid arteriogram and catheterisation show the characteristic abnormalities of the carotid arteriogram found in aortic valve disease and the existence of a trans-aortic or intra-ventricular pressure gradient, when there is an obstruction to left ventricular jection. The F wave of the apex cardiogram or left atrial reflux of the contrast medium during cineangiocardiography, confirm mitral incompetence. The main phono-hemodynamic and phono-anatomical correlations have been emphasized: 1. The intensity of the systolic murmur is directly proportional to the degree of obstructive cardiomyopathy or mitral incompetence, but does not parallel the degree of the sub-valvular apparatus. 3. The maximum intensity of the murmur occurs all the later when the stenosis is tight, whilst it is earlier in severe obstructive cardio-myopathy. 4. The lozange shape of the murmur of mitral incompetence on phono-cardiography is, above all, due to those cases with lesions of the sub-valvular apparatus.

Attention was paid to the existence of the fourth sound, its magnitude, and its vibrational frequency. In general it was accepted that a magnitude of 1/2 of the first heart sound or a frequency of 30 Hz denoted a pathologic fourth sound. However, exceptions were found among normal subjects, so that only the combination of the two criteria could be considered highly significant for a pathologic phenomenon (gallop). Patients with aortic stenosis presented an increase in magnitude of the fourth sound but incidence and vibrational frequency were similar to those of controls. Patients with hypertension had a greater incidence of fourth sounds, especially in middle age (100%); middle age patients usually had a greater magnitude while older patients had more often an increase in vibrational frequency.

This was a 1-year, multicenter, randomized, double-blind, double-dummy study in adult patients with symptomatic asthma that was not controlled by therapy with 200 to 500 microg/d inhaled corticosteroid (ICS) plus a long-acting beta2 agonist, or with &gt;500 to 1000 microg/d ICS alone.

After 4 weeks of stable dosing in both groups, eligible patients continued the study for an additional 48 weeks, receiving either a stable dose of SAL/FP or AMD of FOR/BUD. According to the AMD treatment plan, patients initially halved their dose and subsequently stepped up or down as indicated by the presence or absence of nocturnal awakenings due to asthma, frequency of rescue medication use, and changes in morning peak expiratory flow (PEF). The primary end point was the percentage of symptom-free days. Other parameters included daily asthma symptom scores, morning PEF, percentage of days free of rescue medication use, daily rescue medication use, percentage of nighttime awakenings due to asthma, percentage of weeks with well-controlled asthma, and number of exacerbations requiring oral corticosteroids or emergency department (ED) visits/hospitalizations. Tolerability was assessed in terms of adverse events spontaneously reported or elicited at clinic visits. The intent-to-treat population comprised 688 patients (344 per treatment arm) with a mean age of 45 years and a mean baseline forced expiratory volume in 1 second 81% of the predicted normal value.

Patients in the AMD group with well-controlled asthma stepped down to one inhalation bid; others continued with two inhalations bid. All AMD patients could increase to four inhalations bid for 7-14 days if symptoms worsened. All patients used terbutaline or salbutamol for symptom relief throughout. The primary variable was the odds of achieving a well-controlled asthma week (WCAW).

Treatment with inhaled steroids and bronchodilators often results in good control of symptoms, prevention of further morbidity and mortality and improved quality of life. Several steroids and beta2-agonists (long- and short-acting) as well as combinations of these treatments are available in a single inhaler to be used once or twice a day, with a separate inhaler for relief of symptoms when needed (for patients in Step three or higher, according to Global Initiative for Asthma (GINA) guidelines). Budesonide/formoterol is also licenced for use as maintenance and reliever therapy from a single inhaler (SiT; sometimes referred to as SMART therapy). SiT can be prescribed at a lower dose than other combination therapy because of the additional steroid doses being received as reliever therapy. It has been suggested that using SiT improves compliance and hence reduces symptoms and exacerbations, but it is unclear whether it increases side effects associated with the use of inhaled steroids. To assess the efficacy and safety of budesonide/formoterol in a single inhaler (SiT) to be used for both maintenance and reliever therapy in asthma in comparison with maintenance treatment provided through combination inhalers with a higher maintenance steroid dose (either fluticasone/salmeterol or budesonide/formoterol), along with additional fast-acting beta2-agonists for relief of symptoms. We searched the Cochrane Airways Group Specialised Register of trials, online trial registries and drug company websites. The most recent search was conducted in November 2013. We included parallel-group, randomised controlled trials of at least 12 weeks' duration. Studies were included if they compared single-inhaler therapy with budesonide/formoterol (SiT) versus combination inhalers at a higher maintenance dose of steroids than was given in the SiT arm (either salmeterol/fluticasone or budesonide/formoterol). We used standard methods expected by The Cochrane Collaboration. Primary outcomes were exacerbations requiring hospitalisation, exacerbations requiring oral corticosteroids and serious adverse events (including mortality). Four studies randomly assigning 9130 people with asthma were included; two were six-month double-blind studies, and two were 12-month open-label studies. No trials included children younger than age 12. Trials included more women than men, with mean age ranging from 38 to 45, and mean baseline steroid dose (inhaled beclomethasone (BDP) equivalent) from 636 to 888 μg. Mean baseline forced expiratory volume in one second (FEV1) percentage predicted was between 70% and 73% in three of the trials, and 96% in another. All studies were funded by AstraZeneca and were generally free from methodological biases, although the two open-label studies were rated as having high risk for blinding, and some evidence of selective outcome reporting was found. These possible sources of bias did not lead us to downgrade the quality of the evidence. The quantity of inhaled steroids, including puffs taken for relief from symptoms, was consistently lower for SiT than for the comparison groups.Separate data for exacerbations leading to hospitalisations, to emergency room (ER) visits or to a course of oral steroids could not be obtained. Compared with higher fixed-dose combination inhalers, fewer people using SiT had exacerbations requiring hospitalisation or a visit to the ER (odds ratio (OR) 0.72, 95% confidence interval (CI) 0.57 to 0.90; I(2) = 0%, P = 0.66), and fewer had exacerbations requiring a course of oral corticosteroids (OR 0.75, 95% CI 0.65 to 0.87; I(2) = 0%, P = 0.82). This translates to one less person admitted to hospital or visiting the ER (95% CI 0 to 2 fewer) and two fewer people needing oral steroids (95% CI 1 to 3 fewer) compared with fixed-dose combination treatment with a short-acting beta-agonist (SABA) reliever (per 100 treated over eight months). No statistical heterogeneity was observed in either outcome, and the evidence was rated of high quality. Although issues with blinding were evident in two of the studies, and one study recruited a less severe population, sensitivity analyses did not change the main results, so quality was not downgraded.We could not rule out the possibility that SiT increased rates of serious adverse events (OR 0.92, 95% CI 0.74 to 1.13; I(2) = 0%, P = 0.98; moderate-quality evidence, downgraded owing to imprecision).We were unable to say whether SiT improved results for several secondary outcomes (morning and evening peak expiratory flow (PEF), rescue medication use, symptoms scales), and in cases where results were significant, the effect sizes were not considered clinically meaningful (predose FEV1, nocturnal awakenings and quality of life). SiT reduces the number of people having asthma exacerbations requiring oral steroids and the number requiring hospitalisation or an ER visit compared with fixed-dose combination inhalers. Evidence for serious adverse events was unclear. The mean daily dose of inhaled corticosteroids (ICS) in SiT, including the total dose administered with reliever use, was always lower than that of the other combination groups. This suggests that the flexibility in steroid administration that is possible with SiT might be more effective than a standard fixed-dose combination by increasing the dose only when needed and keeping it low during stable stages of the disease. Data for hospitalisations alone could not be obtained, and no studies have yet addressed this question in children younger than age 12." }, { "id": "pubmed23n0729_22023", "title": "Step-down from high dose fixed combination therapy in asthma patients: a randomized controlled trial.", "score": 0.009615384615384616, "content": "Asthma guidelines suggest that therapy can be reduced once asthma is controlled.

In this 24-week trial undertaken at four primary health-care practices and one hospital in New Zealand, patients (aged 16-65 years) with a recent asthma exacerbation were randomly assigned in a 1:1 ratio to the SMART or standard fixed-dose regimen. Treatment in the SMART group consisted of two actuations of budesonide-formoterol (200 μg and 6 μg, respectively, per actuation) twice daily, delivered through a combination metered dose inhaler (MDI), with one extra actuation as needed for relief of symptoms; treatment in the standard group consisted of two actuations of budesonide-formoterol (200 μg and 6 μg, respectively, per actuation) twice daily through a combination MDI with one to two actuations of salbutamol (100 μg per actuation) by MDI as needed for relief of symptoms. MDIs were monitored electronically to measure actual use of medication. The allocation sequence for randomisation was computer generated, with a block size of eight per site. Participants, investigators, and the statistician were not masked to group assignment.

Lung function measurements were made throughout the study and patients kept daily records of peak expiratory flow (PEF), symptoms and salbutamol usage. Forced expiratory volume in one second and PEF at week 6 were significantly increased by both treatments (p&lt;0.01). PEF variability was reduced by about 30% in both groups. There were significant improvements in asthma symptoms and rescue medication use (p&lt;0.001). There were no significant differences between the treatment groups. The study demonstrated clinical equivalence of theophylline plus beclomethasone dipropionate 400 microg x day(-1) and beclomethasone dipropionate 800 microg x day(-1) in patients whose asthma is not controlled on beclomethasone dipropionate 400 microg x day(-1).

SCA3 is Spinocerebellar Ataxia type 3 also called Machado-Joseph disease. It is caused by mutations in the ATXN3 gene by the CAG triplet repeat expansion mechanism. Affected individuals have between 52 and 86 CAG triplet repeats in heterozygosis with complete penetrance. The heterozygous mutation carrier has the disease as its inheritance pattern is autosomal dominant. In this clinical case, the one who has the disease and has the mutated gene in heterozygosis is the brother (26 years old) of the pregnant woman. I think that before doing the chorion biopsy, the pregnant woman should be tested to know her ATXN3 gene status. She has a 50% chance of carrying the mutation and having the disease, but since she is 31 years old, I think she should have already had symptoms. Nevertheless, I would do the genetic test on the pregnant woman to be on the safe side. If she came out without the mutation, there would be nothing more to do because the disease would no longer be transmitted. If she came out with the mutation, then I would do a chorionic villus biopsy. Answers 1 and 2 are both true, but I think answer 1 is more true than answer 2.
SCA3 is Spinocerebellar Ataxia type 3 also called Machado-Joseph disease. It is caused by mutations in the ATXN3 gene by the CAG triplet repeat expansion mechanism. Affected individuals have between 52 and 86 CAG triplet repeats in heterozygosis with complete penetrance. The heterozygous mutation carrier has the disease as its inheritance pattern is autosomal dominant. In this clinical case, the one who has the disease and has the mutated gene in heterozygosis is the brother (26 years old) of the pregnant woman. I think that before doing the chorion biopsy, the pregnant woman should be tested to know her ATXN3 gene status. She has a 50% chance of carrying the mutation and having the disease, but since she is 31 years old, I think she should have already had symptoms. Nevertheless, I would do the genetic test on the pregnant woman to be on the safe side. If she came out without the mutation, there would be nothing more to do because the disease would no longer be transmitted. If she came out with the mutation, then I would do a chorionic villus biopsy. [HIDDEN]
An asymptomatic 31-year-old woman (Consultant) is asymptomatic and has a 10-week gestation according to ultrasound study (primiparous). Her younger brother (index case) aged 26 years is affected by ataxia and genetically diagnosed as a heterozygous carrier of an expansive mutation of 70 CAG repeats in the SCA3 gene (chromosome 14). The patient is referred to the genetic counseling office where a possible chorionic villus biopsy to study the fetal genotype is evaluated. Is this invasive procedure indicated as a pre-natal diagnosis (PND) in this case?

Five spinocerebellar ataxia genes (SCA1, SCA2, SCA3, SCA6 and SCA7) and another related dominant ataxia gene (DRPLA) have been cloned, allowing the genetic classification of these disorders. We present here the molecular analysis of 87 unrelated familial and 60 sporadic Spanish cases of spinocerebellar ataxia. For ADCA cases 15% were SCA2, 15% SCA3, 6% SCA1, 3% SCA7, 1% SCA6 and 1% DRPLA, an extremely rare mutation in Caucasoid populations. About 58% of ADCA cases remained genetically unclassified. All the SCA1 cases belong to the same geographical area and share a common haplotype for the SCA1 mutation. The expanded alleles ranged from 41 to 59 repeats for SCA1, 35 to 46 [corrected] for SCA2, 67 to 77 for SCA3, and 38 to 113 for SCA7. One SCA6 case had 25 repeats and one DRPLA case had 63 repeats. The highest CAG repeat variation in meiotic transmission of expanded alleles was detected in SCA7, this being of +67 units in one paternal transmission and giving rise to a 113 CAG repeat allele in a patient who died at 3 years of age. Meiotic transmissions have also shown a tendency to more frequent paternal transmission of expanded alleles in SCA1 and maternal in SCA7. All SCA1 and SCA2 expanded alleles analyzed consisted of pure CAG repeats, whereas normal alleles were interrupted by 1-2 CAT trinucleotides in SCA1, except for three alleles of 6, 14 and 21 CAG repeats, and by 1-3 CAA trinucleotides in SCA2.

Clinical classification of these disorders was an important step [2] in differentiation among several types, the most common one being ADCA-I, accompanied with supranuclear ophthalmoplegia, optic nerve atrophy, symptoms of the basal ganglia lesions, dementia and amyotrophia. Molecular-genetic studies indicated genetic heterogeneity of ADCA-I with mutations of genetic loci on chromosome 6p (spinocerebellar ataxia type 1; SCA1), 12q (SCA2), 14q (SCA3), 19p (SCA6) and 16q (SCA4) [3]. Spinocerebellar ataxia type 1 (SCA1) is characterized by cerebellar ataxia, ophthalmoplegia and pyramidal signs [4], but also with other neurological findings that tend to prevent clinical differentiation among patients with SCA1, SCA2 and SCA3. The mutation inducing SCA1 is an instable expansion of trinucleotide (CAG) repeats in the coding region on chromosome 6 [5]. Herein, we report clinical features in patients from two families with SCA1: family I with 15 and family II with 8 affected members in 4 consecutive generations. The acceptable data (history, examination and/or insight into medical records) were obtained for 9 patients in family I and 7 patients in family II. The age at the onset of the disease was 37.8 +/- 11.3 years (mean value +/- SD) (range: 27-60) for all the patients, or 31.8 +/- 10.7 years (range: 7-60) for family I and 45.0 +/- 8.4 years (range: 35-55) for family II.

The mean number of CAG repeats in the mutated allele for SCA1 of the affected individuals was 50.5 +/- 6.2 (range 45-64). A significant inverse correlation (p &lt; 0.05) was noted between the number of CAG repeats and the age at the onset of the disease (Figure 3). Similarity of initial symptoms in SCA1 was noted. They include simultaneous gait-related problems and dysarthria (usually slurred speech). Occurrence of other neurological signs (Table 3) was also predictable in most cases and depended on the phase of SCA1 at the time of examination. Generally, it is believed that intra- and interfamilial phenotypic heterogeneity in SCA1 is lower than in SCA2 and SCA3 [12]). In conclusion, typical clinical manifestations of SCA1, at least in early phases of the disease, according to our study, include gait ataxia, dysarthria, brisk muscle reflexes and marked hand ataxia; the age at the onset of the disease was inverse, and clinical progression was directly related to the number of CAG repeats in the mutated allele on chromosome 6.

The correct answer is 4. Children born to HBV carrier mothers should be administered hepatitis B vaccine and immunoglobulin at different puncture sites within the first 24 hours of life. Although the virus is excreted in breast milk, the risk of infection by this route is very low and therefore it is not currently a contraindication for breastfeeding.

In the western world, hepatitis A, B or C do not seem to influence the course of pregnancy, or to be associated with foetal risks. In contrast, women who contract a hepatitis E infection in their third trimester of pregnancy have a relatively high probability to develop a fulminant hepatitis. Mother-to-infant transmission of hepatitis A seems to be very uncommon. On the contrary, HBsAg and HBeAg positive mothers have a 80-90% risk to transmit the disease to their offspring, more than 85% of these becoming chronic carriers of HBsAg. The risk depends on the level of viral replication. In HBsAg positive and HBeAg negative mothers the rate of transmission is only 2-15%, these babies rarely become carriers. A possible explanation is the transplacental passage of the HBeAg making the infant tolerant to the hepatitis B virus. As most of the infections occur during or directly after delivery, the neonates are suitable for postexposure prophylaxis. It is recommended by the Centers for Disease Control and Prevention and the American Academy of Pediatrics that newborns of HBsAg positive mothers should receive hepatitis B immunoglobulins within 12 hours after birth concurrently with the first paediatric dose of the vaccine.

Local ethics committee approval was obtained at the beginning of the study. The study was carried out between December 2005 and October 2007 among children attending the outpatient clinics of medical school hospital. The study encompassed 912 children (393 female, 519 male; aged 1-5 years old) who had been immunized with three doses of intramuscular recombinant hepatitis B vaccine during infancy. All of the children were born to HBsAg negative mothers and did not have any known immune system problems. Sociodemographic characteristics and passive smoking status were gathered by a questionnaire. Anthropometric measurements were taken, and a detailed physical examination was carried out for each child. Blood samples were obtained to check serum HBsAg, anti-HBs and anti-HBc levels by commercial micro-ELISA (Sanofi Diagnostics Pasteur, Sydney) method. Levels of anti-HBs ≥ 10 mIU/ml were defined as seropositivity. In seronegative children, anti-HBs levels were re-checked 4 weeks after receiving one booster dose of hepatitis B vaccine. Of the children 877 (96.2%) were found anti-HBs positive, while all of them were negative for anti-HBc or HBsAg. Of children 34.8% were 12-23 months; 28.7% were 24-36 months; and 36.5% were 37-60 months-old, and anti-HBs negativity rate was higher in the older age group with a statistically significant difference (1.4%, 3.9% and 4.2%, respectively; p= 0.003). Anti-HBs antibodies were found negative in 2.8% of children who were born by vaginal route and in 5.8% of children who were born by cesarean section, the difference being statistically significant (p= 0.016). There were no significant differences between anti-HBs seropositivity and gender, working/ educational status of the mothers and the presence of smoking parents in the family (p&gt; 0.05). Logistic regression analysis indicated that the factors that affect antibody levels in vaccinated children were the duration of breastfeeding only (4.77 ± 1.53 months in anti-HBs positives and 3.69 ± 2.13 months in negatives; p= 0.008), birth weight (3328.18 ± 318 g in anti-HBs positives and 3135.27 ± 488 g in negatives; p= 0.037) and pregnancy parity (anti-HBs was negative in 3.4% of children born from mothers who had &lt; 2 parities, and 8.2% of children born from mothers who had &lt; 3 parities; p= 0.037). The remaining 35 (3.8%) children with undetectable antibody levels became seropositive after one dose of hepatitis B vaccination, with the antibody levels of ≥ 100 mIU/ml. This response underlined the presence of immune memory in vaccinated children. The results of this study indicated that almost all 1-5 years old children who had received three doses of hepatitis B vaccine during infancy were protected from hepatitis B virus infection.

Orlistat acts by decreasing fat absorption; it is currently the only drug approved for use in obesity.
A patient with obesity (body mass index 38) is referred to your office. In the clinical history the patient refers that he/she has been obese since the age of 17 (currently 36 years old), having been on multiple diets with weight loss ranging from 5 to 10 kg but has subsequently regained weight. The patient is currently on a 1500 Kcal diet (self-administered and not restricted in fat) with a good follow-up of this diet, performing one hour of aerobic exercise 4 days a week. She has lost 3 kg but needs an additional loss of 7 kg more. Given the possibility of adding a drug against obesity, which one would you use to reduce fat absorption?

All human research reported in English, published in peer-reviewed scientific journals within the past 25 y was reviewed. Acceptance criteria (n = 493 from &gt; 700 studies) were that a therapeutic intervention of diet, exercise or diet plus exercise was employed, specifically for weight reduction in obese adult humans and that weight change was reported numerically. Only aerobic exercise studies were included, while drug, hormone and surgical treatments were excluded. All data were extracted by the same investigator from the original research report. Except for gender and program type, all extracted data were numerical. ANOVA, with a Newman-Keuls post hoc test, was used to determine differences among programs (P &lt; 0.05). One analysis was performed on the group mean data and one based on effect sizes. Analyses were repeated using initial body weight, initial percent body fat and program length, as covariates. Primarily, subjects aged 40 y have been studied (39.5 +/- 0.4 y, mean +/- s.e.m.) who are only moderately obese (92.7 +/- 0.9 kg, 33.2 +/- 0.5 body mass index (BMI), 33.4 +/- 0.7% body fat); for short durations (15.6 +/- 0.6 weeks).

The observation that the BMI value associated with the lowest relative mortality is slightly higher in older than in younger adults, mainly through its reduced impact on coronary heart disease, has often been misinterpreted that obesity is not as harmful in the elderly, who suffer a large range of disabling consequences of obesity. All medical consequences of obesity are multi-factorial and most alleviated by modest, achievable weight loss (5-10 kg) with an evidence-based maintenance strategy. But severe obesity, e.g. BMI &gt;40 may demand greater weight loss e.g. &gt;15 kg to reverse type 2 diabetes. Since relatively reduced physical activity and reduced muscle mass (sarcopenic obesity) are common in the elderly, combining exercise and modest calorie restriction optimally reduces fat mass and preserves muscle mass - age presents no obstacle and reducing polypharmacy is a valuable outcome. The currently licensed drug orlistat has no age-related hazards and is effective in a low fat diet, but the risks from bariatric surgery begin to outweigh benefits above age 60. For the growing numbers of obese elderly with diabetes, the glucagon-like peptide-1 (GLP-1) receptor analogue liraglutide appears a safe way to promote and maintain substantial weight loss. Obesity and sarcopenia should be prevented from younger age and during life-transitions including retiral to improve future health outcomes and quality of life, with a focus on those in \"obese families\".

Weight loss is difficult but worth the effort. Although new weight-loss drugs are available, there are no magic bullets: to lose weight and keep it off, people must eat less and exercise more. This article presents a practical approach on how physicians can help their patients lose weight through diet, behavior modification, and adjunctive pharmacologic therapy. An appropriate initial goal is to lose 5% to 10% of one's baseline weight over 3 to 6 months.

These agents decrease appetite, reduce absorption of fat or increase energy expenditure. Primary endpoints used to evaluate anti-obesity drugs most frequently include mean weight loss, percentage weight loss and proportion of patients losing &gt;or=5% and &gt;or=10% of initial bodyweight. Secondary endpoints may include reduction in body fat, risk factors for cardiovascular disease and the incidences of diseases such as diabetes mellitus. Most pharmacotherapies have demonstrated significantly greater weight loss in patients on active treatment than those receiving placebo in short-term (&lt;or=1 year) randomised controlled trials of pharmacological treatment in conjunction with a calorie-controlled diet or lifestyle intervention. The evidence of long-term efficacy is limited to sibutramine (2 years) and orlistat (4 years). These are the only drugs currently approved for the long-term management of obesity in adults.

Clinical trials evaluating ephedrine, bupropion, topiramate and zonisamide have demonstrated significantly greater weight loss than placebo but have been limited to 16-26 weeks' treatment.

A search was conducted for weight-loss-focused randomized clinical trials with &gt;or=1-year follow-up. Eighty studies were identified and are included in the evidence table. The primary outcomes were a measure of weight loss at 6, 12, 24, 36, and 48 months. Eight types of weight-loss interventions-diet alone, diet and exercise, exercise alone, meal replacements, very-low-energy diets, weight-loss medications (orlistat and sibutramine), and advice alone-were identified. By using simple pooling across studies, subjects mean amount of weight loss at each time point for each intervention was determined. Efficacy outcomes were calculated by meta-analysis and provide support for the pooled data. Hedges' gu was combined across studies to obtain an average effect size (and confidence level). A mean weight loss of 5 to 8.5 kg (5% to 9%) was observed during the first 6 months from interventions involving a reduced-energy diet and/or weight-loss medications with weight plateaus at approximately 6 months. In studies extending to 48 months, a mean 3 to 6 kg (3% to 6%) of weight loss was maintained with none of the groups experiencing weight regain to baseline. In contrast, advice-only and exercise-alone groups experienced minimal weight loss at any time point. Weight-loss interventions utilizing a reduced-energy diet and exercise are associated with moderate weight loss at 6 months. Although there is some regain of weight, weight loss can be maintained. The addition of weight-loss medications somewhat enhances weight-loss maintenance." }, { "id": "wiki20220301en180_5549", "title": "Tesofensine", "score": 0.009433962264150943, "content": "Clinical trials Phase IIB trial (TIPO-1) results reported in The Lancet showed levels of weight loss over a 6-month period that were significantly greater than those achieved with any currently available drugs.

Obesity management is a modern challenge because of the rapid evolution of unfavorable lifestyles and unfortunately there are no effective treatments applicable to the large majority of obese/overweight people. The current medical attitude is to treat the complications of obesity (e.g. dyslipidemia, hypertension, diabetes, and cardiovascular diseases). However, the potential of treating obesity is enormous, bearing in mind that a volitional weight loss of 10 kg is associated with important risk factor improvement: blood pressure -10 mmHg, total cholesterol -10%, LDL cholesterol -15%, triglycerides -30%, fasting glucose -50%, HDL cholesterol +8%. Drug treatment for obesity is an evolving branch of pharmacology, burdened by severe side effects and consequences of the early drugs, withdrawn from the market, and challenged by the lack of long-term data on the effect of medications on obesity-related morbidity and mortality, first of all cardiovascular diseases. In Europe three antiobesity drugs are currently licensed: sibutramine, orlistat, and rimonabant; important trials with clinical endpoints are ongoing for sibutramine and rimonabant. While waiting for their results, it is convenient to evaluate these drugs for their effects on body weight and cardiometabolic risk factors. Sibutramine is a centrally acting serotonin/noradrenaline reuptake inhibitor that mainly increases satiety. At the level of brown adipose tissue, sibutramine can also facilitate energy expenditure by increasing thermogenesis. The long-term studies (five) documented a mean differential weight reduction of 4.45 kg for sibutramine vs placebo. Considering the principal studies, attrition rate was 43%. This drug not only reduces body weight and waist circumference, but it decreases triglycerides and uric acid as well and it increases HDL cholesterol; in diabetics it improves glycated hemoglobin. Sibutramine has conflicting effects on blood pressure: in some studies there was a minimal decrease, in some others a modest increase. In all the studies this drug increased pulse rate. Sibutramine is not recommended in patients with uncontrolled hypertension, or in case of history of cardio- and cerebrovascular disease. Orlistat is a pancreatic lipase inhibitor that reduces fat absorption by partially blocking the hydrolysis of dietary triglycerides. A recent meta-analysis evaluated 22 studies lasting for at least 12 months, in obese patients with a mean body mass index of 36.7 kg/m2, where orlistat was associated with hypocaloric diet or behavioral interventions: the net average weight loss was 2.89 kg (confidence interval 2.27-3.51 kg). Considering the principal studies, attrition rate ranged from 33 to 57%. Orlistat significantly decreases waist circumference, blood pressure, total and LDL cholesterol, but has no effect on HDL and triglycerides. This drug significantly reduced the incidence of diabetes only in subjects with impaired glucose tolerance. The major adverse effects with orlistat are mainly gastrointestinal (fatty and oily stool, fecal urgency, oily spotting, fecal incontinence) and attenuate over time. Orlistat should be avoided in patients with chronic malabsorption and cholestasis. Rimonabant is a selective antagonist of cannabinoid type 1 receptor. This drug, by inhibiting the overactivation of the endocannabinoid system, produces anorectic stimuli at the central nervous level, but also has effects on the peripheral systems involved in metabolism control, such as liver, adipose tissue, skeletal muscles, endocrine pancreas, and gastrointestinal apparatus, influencing many processes partially unknown. An ample experimental program named RIO (Rimonabant In Obesity) involved about 6600 obese or overweight patients to identify the effects of rimonabant in weight loss and associated cardiometabolic abnormalities, over and beyond a caloric restriction of 600 kcal in the treatment and placebo arms. In the four double-blind RIO trials published (Rio-North America, RIO-Europe, RIO-Lipids, RIO-Diabetes), rimonabant 20 mg significantly (p &lt;0.001) reduced weight by 6.3-6.9 kg in the non-diabetic groups vs placebo (-1.5-1.8 kg), whereas in the diabetic subjects enrolled in RIO-Diabetes, weight loss was 5.3 vs 1.4 kg in the placebo group. Attrition rate at 1 year ranged between 40 and 50%, similar to the studies with sibutramine or orlistat. Similarly to weight loss, also waist circumference was significantly reduced by rimonabant. As for cardiometabolic parameters, rimonabant induced a significant increase in HDL cholesterol and a significant decrease in triglycerides. Even if no significant LDL reduction was achieved, the RIO-Lipids study showed a significant decrease in small dense LDL particles, more atherogenic, in rimonabant-treated subjects. Non-diabetic treated patients improved basal insulin and indirect indexes of insulin resistance, while in the RIO-Diabetes study, the only one including diabetics, glycated hemoglobin improved by 0.7% in the active treatment arm vs placebo. The effects on HDL cholesterol and glycated hemoglobin seem in a large percentage unrelated to weight loss. These effects have been confirmed by another trial, named SERENADE, evaluating the treatment in naive diabetic patients. Rimonabant is not recommended in patients with a history of depressive disorders or suicidal ideation and with uncontrolled psychiatric illness, and is contraindicated in patients with ongoing major depression or ongoing antidepressive treatment. In conclusion, despite an enormous advancement in basic research to understand the pathogenetic mechanisms at the base of obesity, the pharmacological research did not reach the therapeutic opportunities available for other chronic conditions, like hypertension and dyslipidemia. However, the few molecules available for clinical practice (sibutramine, orlistat, rimonabant) have shown, when properly used, to contribute to reduce body weight and undoubtedly improve cardiometabolic risk factors. With this preamble, according to current guidelines and pharmacoeconomic studies, patients who might benefit from antiobesity treatment are those with a body mass index &gt; or =30 or 27-29.9 kg/m2 with major obesity-related comorbidities such as hypertension, diabetes, dyslipidemia, obstructive sleep apnea, and metabolic syndrome." }, { "id": "pubmed23n0080_1753", "title": "[The base data from Weight Watcher's groups as the parameter for long-term follow-up of weight reduction].", "score": 0.009345794392523364, "content": "The available data of members of Weight Watchers groups were statistically evaluated and their efficiency is discussed with respect to the underlying therapeutic concept. As a result of the data evaluation and the discussion of the literature it can be concluded: 1. The time of active membership in the group correlates with the weight loss. 2. Dropouts can be expected at the beginning of the therapy and have usually a greater obesity than other members. An early motivation has to consider the slower success in those people with a high degree of obesity. 3. A continuous motivation and re-motivation is of greatest importance to prevent any weight gain after the end of group therapy. This re-motivation program should be established within the group; members who succeeded in losing weight should return for meetings at regular intervals." }, { "id": "pubmed23n0610_14679", "title": "Dietary treatment for obesity.", "score": 0.009259259259259259, "content": "In patients with obesity, low-fat diets seem to result in a weight loss of 3-4 kg at 3 years, but long-term data are limited. Calorie-controlled diets seem to outperform low-fat diets with reported weight losses of 6-7 kg at 4 years, but, again, data are very limited; an initial very-low-calorie diet approach does not lead to greater weight loss than low-fat diets in the long term. Use of meal replacements can lead to an 8 kg weight loss at 4 years, but this finding has been reported only in one, uncontrolled study. High-protein, low-carbohydrate (or very-low-carbohydrate) diets have also been evaluated and seem to be superior to high-carbohydrate diets at least for up to 2 years. Very-low-carbohydrate diets can lead to elevations in LDL cholesterol levels in some individuals. Cognitive behavioral therapy added to diet therapy can facilitate approximately 5 kg additional weight loss, and exercise can facilitate an additional 1-1.5 kg weight loss. Drug treatment, particularly with sibutramine and rimonabant, can increase weight loss with a mildly hypocaloric diet by an additional 3-5 kg, but weight-loss drugs are costly and have adverse effects. If dietary and medical therapies fail, gastric banding can lead to a weight loss of approximately 14% at 10 years, with greater losses of up to 25% with gastric bypass and gastroplasty.

Obesity is defined as a body mass index (BMI) of at last 30 kg/m(2).() Morbid obesity is defined as a BMI of at least 40 kg/m(2) or at least 35 kg/m(2) with comorbid conditions. Comorbid conditions associated with obesity include diabetes, hypertension, dyslipidemias, obstructive sleep apnea, weight-related arthropathies, and stress urinary incontinence. It is also associated with depression, and cancers of the breast, uterus, prostate, and colon, and is an independent risk factor for cardiovascular disease. Obesity is also associated with higher all-cause mortality at any age, even after adjusting for potential confounding factors like smoking. A person with a BMI of 30 kg/m(2) has about a 50% higher risk of dying than does someone with a healthy BMI. The risk more than doubles at a BMI of 35 kg/m(2). An expert estimated that about 160,000 people are morbidly obese in Ontario. In the United States, the prevalence of morbid obesity is 4.7% (1999-2000). In Ontario, the 2004 Chief Medical Officer of Health Report said that in 2003, almost one-half of Ontario adults were overweight (BMI 25-29.9 kg/m(2)) or obese (BMI ≥ 30 kg/m(2)). About 57% of Ontario men and 42% of Ontario women were overweight or obese. The proportion of the population that was overweight or obese increased gradually from 44% in 1990 to 49% in 2000, and it appears to have stabilized at 49% in 2003. The report also noted that the tendency to be overweight and obese increases with age up to 64 years. BMI should be used cautiously for people aged 65 years and older, because the \"normal\" range may begin at slightly above 18.5 kg/m(2) and extend into the \"overweight\" range. The Chief Medical Officer of Health cautioned that these data may underestimate the true extent of the problem, because they were based on self reports, and people tend to over-report their height and under-report their weight. The actual number of Ontario adults who are overweight or obese may be higher. Diet, exercise, and behavioural therapy are used to help people lose weight. The goals of behavioural therapy are to identify, monitor, and alter behaviour that does not help weight loss. Techniques include self-monitoring of eating habits and physical activity, stress management, stimulus control, problem solving, cognitive restructuring, contingency management, and identifying and using social support. Relapse, when people resume old, unhealthy behaviour and then regain the weight, can be problematic. Drugs (including gastrointestinal lipase inhibitors, serotonin norepinephrine reuptake inhibitors, and appetite suppressants) may be used if behavioural interventions fail. However, estimates of efficacy may be confounded by high rates of noncompliance, in part owing to the side effects of the drugs. In addition, the drugs have not been approved for indefinite use, despite the chronic nature of obesity. Morbidly obese people may be eligible for bariatric surgery. Bariatric surgery for morbid obesity is considered an intervention of last resort for patients who have attempted first-line forms of medical management, such as diet, increased physical activity, behavioural modification, and drugs. There are various bariatric surgical procedures and several different variations for each of these procedures. The surgical interventions can be divided into 2 general types: malabsorptive (bypassing parts of the gastrointestinal tract to limit the absorption of food), and restrictive (decreasing the size of the stomach so that the patient is satiated with less food). All of these may be performed as either open surgery or laparoscopically. An example of a malabsorptive technique is Roux-en-Y gastric bypass (RYGB). Examples of restrictive techniques are vertical banded gastroplasty (VBG) and adjustable gastric banding (AGB). The Ontario Health Insurance Plan (OHIP) Schedule of Benefits for Physician Services includes fee code \"S120 gastric bypass or partition, for morbid obesity\" as an insured service. The term gastric bypass is a general term that encompasses a variety of surgical methods, all of which involve reconfiguring the digestive system. The term gastric bypass does not include AGB. The number of gastric bypass procedures funded and done in Ontario, and funded as actual out-of-country approvals,() is shown below. Number of Gastric Bypass Procedures by Fiscal Year: Ontario and Actual Out-of-Country (OOC) ApprovalsData from Provider Services, MOHLTCCourtesy of Provider Services, Ministry of Health and Long Term Care The Medical Advisory Secretariat reviewed the literature to assess the effectiveness, safety, and cost-effectiveness of bariatric surgery to treat morbid obesity. It used its standard search strategy to retrieve international health technology assessments and English-language journal articles from selected databases. The interventions of interest were bariatric surgery and, for the controls, either optimal conventional management or another type of bariatric procedure. The outcomes of interest were improvement in comorbid conditions (e.g., diabetes, hypertension); short- and long-term weight loss; quality of life; adverse effects; and economic analysis data. The databases yielded 15 international health technology assessments or systematic reviews on bariatric surgery. Subsequently, the Medical Advisory Secretariat searched MEDLINE and EMBASE from April 2004 to December 2004, after the search cut-off date of April, 2004, for the most recent systematic reviews on bariatric surgery. Ten studies met the inclusion criteria. One of those 10 was the Swedish Obese Subjects study, which started as a registry and intervention study, and then published findings on people who had been enrolled for at least 2 years or at least 10 years. In addition to the literature review of economic analysis data, the Medical Advisory Secretariat also did an Ontario-based economic analysis. Bariatric surgery generally is effective for sustained weight loss of about 16% for people with BMIs of at least 40 kg/m(2) or at least 35 kg/m(2) with comorbid conditions (including diabetes, high lipid levels, and hypertension). It also is effective at resolving the associated comorbid conditions. This conclusion is largely based on level 3a evidence from the prospectively designed Swedish Obese Subjects study, which recently published 10-year outcomes for patients who had bariatric surgery compared with patients who received nonsurgical treatment. (1)Regarding specific procedures, there is evidence that malabsorptive techniques are better than other banding techniques for weight loss and resolution of comorbid illnesses. However, there are no published prospective, long-term, direct comparisons of these techniques available.Surgery for morbid obesity is considered an intervention of last resort for patients who have attempted first-line forms of medical management, such as diet, increased physical activity, behavioural modification, and drugs. In the absence of direct comparisons of active nonsurgical intervention via caloric restriction with bariatric techniques, the following observations are made:A recent systematic review examining the efficacy of major commercial and organized self-help weight loss programs in the United States concluded that the evidence to support the use of such programs was suboptimal, except for one trial on Weight Watchers. Furthermore, the programs were associated with high costs, attrition rates, and probability of regaining at least 50% of the lost weight in 1 to 2 years. (2)A recent randomized controlled trial reported 1-year outcomes comparing weight loss and metabolic changes in severely obese patients assigned to either a low-carbohydrate diet or a conventional weight loss diet. At 1 year, weight loss was similar for patients in each group (mean, 2-5 kg). There was a favourable effect on triglyceride levels and glycemic control in the low-carbohydrate diet group. (3)A decision-analysis model showed bariatric surgery results in increased life expectancy in morbidly obese patients when compared to diet and exercise. (4)A cost-effectiveness model showed bariatric surgery is cost-effective relative to nonsurgical management. (5)Extrapolating from 2003 data from the United States, Ontario would likely need to do 3,500 bariatric surgeries per year. It currently does 508 per year, including out-of-country surgeries." }, { "id": "wiki20220301en420_15136", "title": "The Biggest Loser (season 15)", "score": 0.009174311926605505, "content": "Winners $250,000 Winner (among the finalists) $100,000 Winner (among the eliminated contestants) Weigh-In Difference History Notes Rachel's 4 pound weight loss in week 10 was displayed as -5 due to her 1-pound advantage from the challenge.

The aims of this study were to investigate the atypical serologic profiles seen in patients screened for HBV infection and the S gene mutations in patients with concurrent positivity of HBsAg and anti-HBs. A total of 592 sera from patients (332 male, 260 female; age range: 13-84 years, mean age: 43.9 years) prediagnosed as HBV infection between January to September 2013, and screened for HBV markers (HBsAg, anti-HBs, HBeAg, anti-HBe, anti-HBc-IgM, anti-HBc-total and HBV-DNA) were included in the study. Of those samples 364 were screened only for HBsAg and anti-HBs markers. S gene mutations were investigated by direct sequencing method in sera which were concurrent positive for HBsAg and anti-HBs. In our study, 5.2% (31/592) of the sera yielded atypical serologic profiles. Of these 13 cases were concurrently positive for HBsAg and anti-HBs; nine were HBeAg positive, anti-HBe and HBV-DNA negative; eight were HBeAg, anti-HBe and HBV-DNA positive; and one was HBsAg and anti-HBs negative, anti-HBe and HBV-DNA positive. The rate of concurrent positivity of HBsAg and anti-HBs was 3.6% (13/364), while 76.9% (10/13) of those cases were also positive for HBV-DNA. DNA sequencing was performed for seven out of 10 samples which were positive for HBsAg, anti-HBs and HBV-DNA, however three samples were not used because of the low amounts. Sequence analysis of seven samples showed S gene mutations in two samples, one was sS143L with sS193L, a HBV vaccine escape mutation, and the other was sP120R, a HBV immune escape mutation. Of the patients 2.7% (10/364) was negative for both HBsAg and anti-HBs; in which nine were HBV-DNA negative and anti-HBe positive, while one was positive for both HBV-DNA and anti-HBe. The rate of concurrent positivity of HBeAg and anti-HBe was found as 1.4% (8/592), and all of these samples were HBV-DNA positive. No single positivity for HBsAg, anti-HBc, anti-HBs or HBV-DNA was not detected in any of the patients.

Our investigations indicate that the diffuse and focal forms of persistent hepatitis can remain unchanged overlong periods and the same histological findings over a number of years. The chronic persistent hepatitis, however, may develop through clinically imperceptible changes into a chronic aggressive hepatitis, and the inapparent acute hepatitis can even pass over directly into cirrhosis. The identification of various forms of hepatitis, from light instances to the most severe cases, among the HB antigen carriers proves that the acute viral hepatitis of the type B may have in all the phases of its development a clinically asymptomatic course; it may even asymptomatically pass over into hepatopathies of the most severe kinds.

There were two significant findings in this study: a) In 1987-88 [corrected], 8-9% of HBsAg-positive individuals had HBeAg and 64-81% had anti-HBe, while in 1980-82, 36% of those positive for HBsAg had HBeAg and only 25% had anti-HBe. b) At the time of arrival recent infection by HBV was indicated by the presence of IgM anti-HBc in 57% of those positive for HBsAg and 21% in whom anti-HBc was the sole serological HBV marker. In 1987-88 no IgM anti-HBc was found in HBsAg-positive persons or in those with anti-HBc only. These results indicate that most HBV infections in this population had occurred before their arrival in Israel.

The test results of 56 years old male patient who suffered from fatigue and pain on the right upper quadrant, revealed high levels of liver enzymes (AST: 187 U/L, ALT: 569 U/L), positivity of HBsAg, anti-HBc IgG and anti-HBe, and negativity of anti-HBc IgM, HBeAg and anti-HBs. Since HBV-DNA level was found 405,974 copies/mL by quantitative real time polymerase chain reaction (PCR), the patient was taken into follow-up.

Laboratory results showed hyperkalemia, elevated kidney function tests, indirect hyperbilirubinemia, increased liver function tests, leukocytosis, anemia, thrombocytopenia and elevated international normalized ratio (INR). He was treated with saline infusions, four units of red blood cells and one unit of fresh frozen plasma transfusions. Four days later he was transported to our Institution with ARF. Physical examination revealed dyspnoe, petechiae, hemoptoe, oliguria, chest-wall pain and aggressive behavior. Thrombocytopenia, signs of MAHA (fragmentocytes and helmet cells in the peripheral blood), normal INR, elevated lactate dehydrogenase (LDH) and ARF suggested TTP-HUS. Hemodialysis and six plasmaferesis (PF) were carried out. After the fifth PF, skin manifestations of thrombotic microangiopathy occurred on the feet. Clotting analysis revealed elevated D-dimer (&gt;5 μg/mL), normal fibrinogen (3.2 g/L), a slightly raised INR (1.36) and activated partial prothrombin time (APTT) (45.8 sec), normal reticulocyte (57 G/L) and a slightly low platelet count (123 G/L), which proved to be chronic DIC. Therapeutic dose of low-molecular-weight heparin (LMWH) was started. Elevated prostate-specific antigen (PSA) (109.6 ng/mL) suggested prostatic carcinoma. Prostate biopsy revealed adenocarcinoma (Gleason: 4+4 for left lobe and 3+3 for right lobe). Elevated alkaline phosphatase suggested metastases in the bone, which were confirmed by bone scintigraphy. Combined androgen blockade (CAB) was started. After three months follow-up our patient's status is satisfactory. PSA is in the normal range (4.6 ng/mL). Thrombocytopenia of uncertain origin with normal or raised INR, APTT, elevated D-dimer, normal fibrinogen and reticulocyte count prove the diagnosis of chronic DIC. This process warrants searching for metastatic neoplasia. Due to the relatively low serum levels of circulating procoagulant factors (e.g. tissue factor), therapeutic dose of LMWH can be used with good efficiency in chronic DIC with low risk of bleeding. Severe DIC as a complication of metastatic prostate cancer can be treated by androgen deprivation therapy (ADT) or CAB in combination with ketokonazole and concomitant use of supportive treatment.

Advanced pernicious anemia is thought to cause intramedullary hemolysis, resulting in peripheral pancytopenia. The fragile RBCs are easily sheared, producing schistocytosis without platelet microthrombi. In contrast to hemolytic anemias, reticulocyte count is low given the unavailability of B12 for erythropoiesis. Reticulocytopenia is a universal finding in cases of pseudo-TMA.

Far fewer situations exist, however, in which these analyses are the main clue in establishing an emergency diagnosis. Artifacts can lead to wrong diagnosis, e.g. pseudo-thrombocytopenia, which is defined as a low platelet count resulting from a laboratory artifact. Severe neutropenia (agranulocytosis) and extreme hyperleukocytosis, as well as suspicion of acute leukemia, require a rapid diagnostic work-up. A newly detected anemia should not necessarily be treated by packed red cell transfusions. The decision whether an anemic patient ought to receive transfusions should be based on the speed with which the anemia has developed, as well as on clinical judgement. As a rule a chronic anemia patient with hemoglobin above 70 g/l does not need transfusions. An uncritical transfusion policy can even cause emergencies, e.g. in patients with megaloblastic anemia or in anemic multiple myeloma patients with a hyperviscosity syndrome. An elevated hematocrit requires prompt further investigations. This is of utmost importance if one considers the diagnosis of polycythemia vera rubra, a disease in which patients are particularly prone to thrombotic complications. Fragmented red cells (schistocytes) on peripheral blood smears constitute a cardinal diagnostic clue for the detection of microangiopathic hemolytic anemias (MAHA), in particular for the diagnosis of the life-threatening thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS). Malaria is another example for a chief role of blood smears examination in achieving a rapid diagnosis. If one encounters an unexpected severe thrombocytopenia, a marrow examination reveals whether it is due to rapid peripheral destruction, or due to a marrow failure. Furthermore, in any patients with an unanticipated thrombocytopenia, a disseminated intravascular coagulation and a MAHA should be ruled out.

It represents the acquired megakaryocytic thrombocytopenia with the shortened life of platelets because of immunologic damage (antibodies absorbed by platelets). In the case of this acquired hemorrhagic disorder, in spite of compensatory increased function of the bone marrow, there is a reduced number of platelets because of their increased destruction by the reticuloendothelial system (destructive thrombocytopenia). There are three forms of ITP: acute, chronic and intermittent. The acute form occurs in 80-90% of cases with bleeding episodes lasting a few days or weeks, but no longer than 6 months. The chronic form occurs in 10-15% of children, while the rarest-intermittent form is characterized by periods of normalization in regard to the number of platelets but also with relapse in intervals of 1-3 months. The disease is caused by an immunological disorder in the sense of an imbalanced immune response. Immunologic damages of platelets cause shortening of the opsonized platelets life span. The most frequent platelet opsonins are the immumoglobulin G (IgG) antibodies directed at the platelet membrane in the form of autoantibodies, alloantibodies or possibly absorbed antigen caused by microorganism infection or drug intake. It is typical for the phenomenon of bleeding that it starts suddenly and without any other sign of illness. The most frequent acute form appears between the second and fourth year, and is characterized by seasonal occurrence usually after acute viral infections. Children older than 10 years of age, like adults, often have the chronic form associated with other immunologic disorders. The disease affects girls more often than boys (about three times more often) with moderate and constant increase of antiplatelet antibodies. Hemorrhagic manifestations include: petechiae, purpura, epistaxis, gastrointestinal and genitourinary bleeding. They depend on the grade of thrombocytopenia, although there is no strict correlation between the number of platelets and volume of bleeding. Low mortality of the acute ITP is almost exclusively due to intracranial hemorrhage. LABORATORY STUDIES: Thrombocytopenia represents a decrease in the number of blood platelets being a basic abnormality of the blood count. The half-life of platelets in ITP is shortened. Detection of antiplatelet antibodies is connected with technical difficulties, so they are established in about 30% of cases. Bleeding time is prolonged and so is the coagulum retraction which may be completely missed. The Rumpel-Leede test is positive. Clinical differentiation of drug-induced thrombocytopenia is not possible. However, other differential diagnostic possibilities are thrombotic-thrombocytopenic purpura and hemolytic-uremic syndrome. A child with aplastic anemia or acute leukemia, beside thrombocytopenia, has a characteristic finding of white and red blood cell count. Thrombocytopenia with absent radii syndrome is associated with skeletal system abnormalities. New knowledge about the role of the immune system in ITP determines the modern therapeutic modalities. In cases of acute ITP in children, there are two therapeutic options or therapies of choice: corticosteroids and high doses of intravenous immunoglobulin. Immunosupressive therapy means anti Rh(D) immunoglobulin, cyclosporine, cytostatics, danazol, loaded platelets. In cases of distinctive hemorrhagic syndrome there are also indications for platelet transfusion.

Basically two types of DIC are distinguished: (1) chronic (compensated) - with alteration of laboratory values and (2) acute (non-compensated) - with severe clinical manifestations: bleeding, shock, acute renal failure (ARF), transient focal neurologic deficit, delirium or coma. Chronic DIC related to metastatic neoplasia is caused by pancreatic, gastric or prostatic carcinoma in most of the cases. Incidence rate of DIC is 13-30% in prostate cancer, among those only 0.4-1.65% of patients had clinical signs and symptoms of DIC. In other words, chronic DIC is developed in one of eight patients with prostate cancer. DIC is considered as a poor prognostic factor in prostatic carcinoma. The similar clinical and laboratory findings of TTP-HUS (thrombotic thrombocytopenic purpura - hemolytic uremic syndrome) and DIC makes it difficult to differentiate between them. A 71 years old male patient with known chronic obstructive pulmonary disease, benign prostatic hyperplasia, significant carotid artery stenosis, gastric ulcer and alcoholic liver disease was admitted to another hospital with melena. Gastroscopy revealed intact gastric mucosa and actually non-bleeding duodenal ulcer covered by clots. Laboratory results showed hyperkalemia, elevated kidney function tests, indirect hyperbilirubinemia, increased liver function tests, leukocytosis, anemia, thrombocytopenia and elevated international normalized ratio (INR). He was treated with saline infusions, four units of red blood cells and one unit of fresh frozen plasma transfusions. Four days later he was transported to our Institution with ARF. Physical examination revealed dyspnoe, petechiae, hemoptoe, oliguria, chest-wall pain and aggressive behavior. Thrombocytopenia, signs of MAHA (fragmentocytes and helmet cells in the peripheral blood), normal INR, elevated lactate dehydrogenase (LDH) and ARF suggested TTP-HUS. Hemodialysis and six plasmaferesis (PF) were carried out. After the fifth PF, skin manifestations of thrombotic microangiopathy occurred on the feet. Clotting analysis revealed elevated D-dimer (&gt;5 μg/mL), normal fibrinogen (3.2 g/L), a slightly raised INR (1.36) and activated partial prothrombin time (APTT) (45.8 sec), normal reticulocyte (57 G/L) and a slightly low platelet count (123 G/L), which proved to be chronic DIC. Therapeutic dose of low-molecular-weight heparin (LMWH) was started. Elevated prostate-specific antigen (PSA) (109.6 ng/mL) suggested prostatic carcinoma. Prostate biopsy revealed adenocarcinoma (Gleason: 4+4 for left lobe and 3+3 for right lobe). Elevated alkaline phosphatase suggested metastases in the bone, which were confirmed by bone scintigraphy. Combined androgen blockade (CAB) was started. After three months follow-up our patient's status is satisfactory. PSA is in the normal range (4.6 ng/mL). Thrombocytopenia of uncertain origin with normal or raised INR, APTT, elevated D-dimer, normal fibrinogen and reticulocyte count prove the diagnosis of chronic DIC. This process warrants searching for metastatic neoplasia. Due to the relatively low serum levels of circulating procoagulant factors (e.g. tissue factor), therapeutic dose of LMWH can be used with good efficiency in chronic DIC with low risk of bleeding. Severe DIC as a complication of metastatic prostate cancer can be treated by androgen deprivation therapy (ADT) or CAB in combination with ketokonazole and concomitant use of supportive treatment.

A newly detected anemia should not necessarily be treated by packed red cell transfusions. The decision whether an anemic patient ought to receive transfusions should be based on the speed with which the anemia has developed, as well as on clinical judgement. As a rule a chronic anemia patient with hemoglobin above 70 g/l does not need transfusions. An uncritical transfusion policy can even cause emergencies, e.g. in patients with megaloblastic anemia or in anemic multiple myeloma patients with a hyperviscosity syndrome. An elevated hematocrit requires prompt further investigations. This is of utmost importance if one considers the diagnosis of polycythemia vera rubra, a disease in which patients are particularly prone to thrombotic complications. Fragmented red cells (schistocytes) on peripheral blood smears constitute a cardinal diagnostic clue for the detection of microangiopathic hemolytic anemias (MAHA), in particular for the diagnosis of the life-threatening thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS). Malaria is another example for a chief role of blood smears examination in achieving a rapid diagnosis. If one encounters an unexpected severe thrombocytopenia, a marrow examination reveals whether it is due to rapid peripheral destruction, or due to a marrow failure. Furthermore, in any patients with an unanticipated thrombocytopenia, a disseminated intravascular coagulation and a MAHA should be ruled out. Heparin-induced thrombocytopenia is a rare, but possibly fatal complication of therapy with heparins." }, { "id": "pubmed23n0059_11730", "title": "[Thrombotic thrombocytopenic pupura (TTP)--remission following treatment with high-dose immunoglobulin].", "score": 0.013844974609562135, "content": "A 60-year-old man was admitted to our hospital because of fever, hemorrhagic tendency, anemia and neurological abnormality.

It represents the acquired megakaryocytic thrombocytopenia with the shortened life of platelets because of immunologic damage (antibodies absorbed by platelets). In the case of this acquired hemorrhagic disorder, in spite of compensatory increased function of the bone marrow, there is a reduced number of platelets because of their increased destruction by the reticuloendothelial system (destructive thrombocytopenia). There are three forms of ITP: acute, chronic and intermittent. The acute form occurs in 80-90% of cases with bleeding episodes lasting a few days or weeks, but no longer than 6 months. The chronic form occurs in 10-15% of children, while the rarest-intermittent form is characterized by periods of normalization in regard to the number of platelets but also with relapse in intervals of 1-3 months. The disease is caused by an immunological disorder in the sense of an imbalanced immune response. Immunologic damages of platelets cause shortening of the opsonized platelets life span. The most frequent platelet opsonins are the immumoglobulin G (IgG) antibodies directed at the platelet membrane in the form of autoantibodies, alloantibodies or possibly absorbed antigen caused by microorganism infection or drug intake. It is typical for the phenomenon of bleeding that it starts suddenly and without any other sign of illness. The most frequent acute form appears between the second and fourth year, and is characterized by seasonal occurrence usually after acute viral infections. Children older than 10 years of age, like adults, often have the chronic form associated with other immunologic disorders. The disease affects girls more often than boys (about three times more often) with moderate and constant increase of antiplatelet antibodies. Hemorrhagic manifestations include: petechiae, purpura, epistaxis, gastrointestinal and genitourinary bleeding. They depend on the grade of thrombocytopenia, although there is no strict correlation between the number of platelets and volume of bleeding. Low mortality of the acute ITP is almost exclusively due to intracranial hemorrhage. LABORATORY STUDIES: Thrombocytopenia represents a decrease in the number of blood platelets being a basic abnormality of the blood count. The half-life of platelets in ITP is shortened. Detection of antiplatelet antibodies is connected with technical difficulties, so they are established in about 30% of cases. Bleeding time is prolonged and so is the coagulum retraction which may be completely missed. The Rumpel-Leede test is positive. Clinical differentiation of drug-induced thrombocytopenia is not possible. However, other differential diagnostic possibilities are thrombotic-thrombocytopenic purpura and hemolytic-uremic syndrome. A child with aplastic anemia or acute leukemia, beside thrombocytopenia, has a characteristic finding of white and red blood cell count. Thrombocytopenia with absent radii syndrome is associated with skeletal system abnormalities. New knowledge about the role of the immune system in ITP determines the modern therapeutic modalities. In cases of acute ITP in children, there are two therapeutic options or therapies of choice: corticosteroids and high doses of intravenous immunoglobulin. Immunosupressive therapy means anti Rh(D) immunoglobulin, cyclosporine, cytostatics, danazol, loaded platelets. In cases of distinctive hemorrhagic syndrome there are also indications for platelet transfusion. Nowadays splenectomy is more restricted, because one third of cases is unsuccessful, whereas plasmapheresis is rarely used in children because of possible complications. ITP is the most frequent hemorrhagic disease in children. The disease is basically caused by an immunologic disorder with platelet destruction due to increased immunoglobulin on their membrane.
