    Trisomy 13 or Patau syndrome (PS) is a chromosomal disorder characterized by a well known presentation of multiple congenital anomalies. Our objective was to determine the clinical features and prognosis observed in a sample of patients with PS. The series was composed of patients with diagnosis of PS consecutively evaluated by a Clinical Genetics Service from a reference hospital of southern Brazil, in the period between 1975 and 2012. Statistical analysis was performed using PEPI program (version 4.0), with two-tailed Fisher's exact test for comparison of frequencies (P<0.05). The sample consisted of 30 patients, 60% male, median age at first evaluation of 9 days. Full trisomy of chromosome 13 was the main cytogenetic alteration (73%). The major clinical findings included: cryptorchidism (78%), abnormal auricles (77%), congenital heart defects (76%), polydactyly (63%), microphthalmia (60%) and micrognathia (50%). Four patients (13%) simultaneously had micro/anophthalmia, oral clefts and polydactyly. Some findings were only observed in our sample and included, among others, preauricular tags (10%), duplication of the hallux (3%) and spots following the lines of Blaschko (3%). Mosaicism (20% of cases) had a statistically significant association only with absence of cryptorchidism. The median of survival was 26 days. Patients with and without mosaicism had similar median of survival. Our findings, in agreement with the literature, show that the anomalies in patients with PS can be quite variable, sometimes even atypical. There is no pathognomonic finding, which may make the early identification of these patients challenging.

    To identify the clinical and epidemiological profile of cryptococcosis diagnosed at the University Hospital of the Federal University of Mato Grosso do Sul, Brazil, medical records of 123 patients admitted from January 1995 to December 2005 were analyzed. One hundred and four cases (84.5%) had HIV infection, six (4.9%) had other predisposing conditions and 13 (10.6%) were immunocompetent. Male patients predominated (68.3%) and their age ranged from 19 to 69 years (mean: 35.9). Most patients (73.2%) were born and lived lifelong in the state of Mato Grosso do Sul. Involvement of the central nervous system occurred in 103 patients (83.7%) and headache and vomiting were the most frequent symptoms. In 77 cases it was possible to identify the Cryptococcus species: 69 (89.6%) C. neoformans and eight (10.4%) C. gattii. Amphotericin B was the drug of choice for treatment (106/123), followed by fluconazole in 60% of cases. The overall lethality rate was 49.6%, being 51% among the HIV infected patients and 41.2% among the non-HIV infected (p > 0.05). Although cryptococcosis exhibited in our region a similar behavior to that described in the literature, the detection of an important rate of immunocompetent individuals and five C. gattii cryptococcosis in HIV-infected patients is noteworthy.

    Full Text Available Abstract Background Childhood pneumonia and bronchiolitis is a leading cause of illness and death in young children worldwide with Respiratory Syncytial Virus (RSV as the main viral cause. RSV has been associated with annual respiratory disease outbreaks and bacterial co-infection has also been reported. This study is the first RSV epidemiological study in young children hospitalized with community-acquired pneumonia (CAP in Belém city, Pará (Northern Brazil. Methods With the objective of determining the prevalence of RSV infection and evaluating the patients’ clinical and epidemiological features, we conducted a prospective study across eight hospitals from November 2006 to October 2007. In this study, 1,050 nasopharyngeal aspirate samples were obtained from hospitalized children up to the age of three years with CAP, and tested for RSV antigen by direct immunofluorescence assay and by Reverse Transcription Polymerase Chain Reaction (RT-PCR for RSV Group identification. Results RSV infection was detected in 243 (23.1% children. The mean age of the RSV-positive group was lower than the RSV-negative group (12.1 months vs 15.5 months, pppppp Conclusion The present study highlights the relevance of RSV infection in hospitalized cases of CAP in our region; our findings warrant the conduct of further investigations which can help design strategies for controlling the disease.

    Full Text Available Introduction Celiac disease is an autoimmune disorder that involves gluten intolerance and can be triggered by environmental factors including hepatitis B virus (HBV infection. This study aimed to describe the prevalence of celiac disease in individuals with HBV infection and to describe the clinical and laboratory characteristics of celiac disease associated with HBV. Methods This cross-sectional study included 50 hepatitis B patients tested for IgA anti-endomysial antibodies (EMAs and tissue anti-transglutaminase (TTG between August 2011 and September 2012. Results Fifty patients were included with a mean age of 46.0 ± 12.6 (46.0 years; 46% were female and 13% were HBeAg+. Six patients had positive serology for celiac disease, four were EMA+, and five were TTG+. When individuals with positive serology for celiac disease were compared to those with negative serology, they demonstrated a higher prevalence of abdominal pain (100% vs. 33.3%, p = 0.008, lower median creatinine (0.7mg/dL vs. 0.9mg/dL, p = 0.007 and lower mean albumin (3.6 ± 0.4g/L vs. 3.9 ± 0.3g/L, p = 0.022. All individuals with positive serology for celiac disease underwent upper digestive endoscopy, and three of the patients exhibited a macroscopic pattern suggestive of celiac disease. Histologically, five patients demonstrated an intra-epithelial lymphocytic infiltrate level > 30%, and four patients showed villous atrophy associated with crypt hyperplasia on duodenal biopsy. Conclusions An increased prevalence of celiac disease was observed among hepatitis B patients. These patients were symptomatic and had significant laboratory abnormalities. These results indicate that active screening for celiac disease among HBV-infected adults is warranted.

    Full Text Available Introduction In this study, the clinical features, underlying diseases and clinical outcomes of patients with cryptococcosis were investigated. In addition, a molecular analysis of the Cryptococcus neoformans species complex isolated from these patients was performed. Methods A prospective study of 62 cases of patients with cryptococcal infection was conducted at the Hospital de Doenças Tropicais de Goiás Dr. Anuar Auad from 2009-2010. Cryptococcal meningitis cases were diagnosed by direct examination and cerebrospinal fluid (CSF sample culture. The profiling of these patients was assessed. The CSF samples were submitted to India ink preparation and cultured on Sabouraud dextrose agar, and C. neoformans was identified by the production of urease, a positive phenoloxidase test and assimilation of carbohydrates. C. neoformans and C. gattii isolates were distinguished by growth on L-canavanine-glycine-bromothymol blue medium, and molecular analysis was conducted via PCR fingerprinting reactions using M13 and (GACA4 primers. Results From the 62 patients with cryptococcosis, 71 isolates of CSF were obtained; 67 (94.4% isolates were identified as C. neoformans var. grubii/VNI, and 4 (5.6% were identified as C. gattii/VGII. Of these patients, 53 had an HIV diagnosis. The incidence of cryptococcosis was higher among patients 20-40 years of age, with 74.2% of the cases reported in males. Cryptococcus-related mortality was noted in 48.4% of the patients, and the symptoms were altered sensorium, headache, fever and stiff neck. Conclusions The high morbidity and mortality observed among patients with cryptococcosis demonstrate the importance of obtaining information regarding the epidemiological profile and clinical course of the disease in the State of Goiás, Brazil.

    Full Text Available Consensual unions are a well-known practice among the lower social strata in Latin America. However, this type of union is increasing in the region, among higher educated groups and in countries where they were never widespread, such as in Brazil. This study uses couples' data from the demographic census available at IPUMS (N=193,689 to identify the socioeconomic and cultural features of consensual unions in Brazil. The effects of women's education, couples' income, children, and religion on nuptial behavior are analyzed. Utilizing logistic multilevel analysis, special attention is paid to the effect of differences in the cultural environment of states in the five major regions in which these unions occur. Results indicate that socioeconomic factors affect the incidence of consensual unions in Brazil. Consensual unions are more common among lower income couples and less educated women, but are also found among the upper classes. Cultural diversity between Brazilian states is also reflected in nuptial behavior. Significant variance at the state level is partially explained by the ethnic composition of each state.

    2010-03-01

    Neurotoxicity from intravenous fludarabine is a rare but recognized clinical entity. Its brain imaging features have not been extensively described. Three patients received 38.5 mg or 40 mg/m per day fludarabine in a 5-day intravenous infusion before bone marrow transplantation in treatment of hematopoietic malignancies. Several weeks later, each patient developed progressive neurologic decline, including retrogeniculate blindness, leading to coma and death. Brain MRI showed progressively enlarging but mild T2/FLAIR hyperintensities in the periventricular white matter. The lesions demonstrated restricted diffusion but did not enhance. Because the neurotoxicity of fludarabine appears long after exposure, neurologic decline in this setting is likely to be attributed to opportunistic disease. However, the imaging features are distinctive in their latency and in being mild relative to the profound clinical features. The safe dose of fludarabine in this context remains controversial.

    2016-05-01

    Full Text Available ABSTRACT: Conidiobolomycosis is an emerging disease caused by fungi of the cosmopolitan genus Conidiobolus . Particular strains of Conidiobolus coronatus, Conidiobolus incongruus and Conidiobolus lamprauges , mainly from tropical or sub-tropical origin, cause the mycosis in humans and animals, domestic or wild. Lesions are usually granulomatous and necrotic in character, presenting two clinical forms: rhinofacial and nasopharyngeal. This review includes the main features of the disease in sheep, with an emphasis on the epidemiology, clinical aspects, and diagnosis of infections caused by Conidiobolus spp. in Brazil. In this country, the disease is endemic in the Northeast and Midwest, affecting predominantly woolless sheep breeds and occasioning death in the majority of the studied cases. The species responsible for infections of sheep are C. coronatus and C. lamprauges and the predominant clinical presentation is nasopharyngeal. These fungal infections are very important, since they compromise the health status of the sheep flock and cause serious economic losses to the sheep industry. Thus, research is needed to investigate faster tools for diagnosis and effective methods for the control and treatment of conidiobolomycosis.

    Jarius, S; Wildemann, B; Paul, F

    2014-05-01

    The term 'neuromyelitis optica' ('Devic's syndrome', NMO) refers to a syndrome characterized by optic neuritis and myelitis. In recent years, the condition has raised enormous interest among scientists and clinical neurologists, fuelled by the detection of a specific serum immunoglobulin (Ig)G reactivity (NMO-IgG) in up to 80% of patients with NMO. These autoantibodies were later shown to target aquaporin-4 (AQP4), the most abundant water channel in the central nervous system (CNS). Here we give an up-to-date overview of the clinical and paraclinical features, immunopathogenesis and treatment of NMO. We discuss the widening clinical spectrum of AQP4-related autoimmunity, the role of magnetic resonance imaging (MRI) and new diagnostic means such as optical coherence tomography in the diagnosis of NMO, the role of NMO-IgG, T cells and granulocytes in the pathophysiology of NMO, and outline prospects for new and emerging therapies for this rare, but often devastating condition.

    Objective To evaluate the clinical and pathological features of Riedel's thyroiditis (RT), and current diagnostic and treatment methods for that disease.Methods Five RT cases identified by surgery and pathological examinations at Peking Union Medi-cal College Hospital from 1985 to 2009 were analyzed and compared with the cases reported in the litera-ture in terms of clinical and pathological features. Immunohistochemical staining of kappa and lambda light chains was carried out for RT tissues from all the five patients.Results All the five cases were females, aged 45-55 years. Elevation of serum thyroid autoantibodies was found in only one patient, who had longer disease duration than the others. Pathological examination re-vealed invasive fibrosclerosis of the thyroid follicles, thyroid capsule, and the surrounding tissues. In RT tis-sues, the number of cells containing lambda chains was a little higher than those containing kappa chains.Conclusions RT is a rare disease which might be more common in middle-aged females than in other populations. Pathological features include the destruction of thyroid follicle, extension into surround-ing tissues by inflammatory cells and fibrous tissues. Immunohistochemical staining of kappa and lambda chains could help diagnose RT.

    Full Text Available Considering the relevance of AIDS/tuberculosis comorbidity worldwide, especially in Brazil, this study was developed to describe the clinical and epidemiological features of the comorbid cases identified from 1989 to 1997 by the epidemiology service of the Hospital das Clínicas of the Universidade de São Paulo. METHODS: Databases containing information on all identified AIDS/tuberculosis cases cared for at the hospital were used to gather information on comorbid cases. RESULTS: During the period, 559 patients were identified as presenting with AIDS/tuberculosis comorbidity. Risk behavior for AIDS was primarily heterosexual contact (38.9%, followed by intravenous drug use (29.3% and homosexual/bisexual contact (23.2%. Regarding clinical features, there were higher rates of extrapulmonary tuberculosis when compared to tuberculosis without comorbidity. There was an increase in reporting of AIDS by ambulatory units during the period. Epidemiologically, there was a decrease in the male/female ratio, a predominance in the 20 to 39 year-old age group, and a majority of individuals who had less than 8 years of schooling and had low professional qualifications. CONCLUSIONS: High rates of AIDS/tuberculosis cases at our hospital indicate the need for better attention towards early detection of tuberculosis, especially in its extrapulmonary form. Since the population that attends this hospital tends to be of a lower socioeconomic status, better management of AIDS and tuberculosis is required to increase the rates of treatment adherence and thus lower the social costs.

    Full Text Available Background: Intraocular medulloepithelioma arises from the primitive medullary epithelium and is diagnosed at a median age of five years. This tumor most commonly appears as a white, gray, or yellow-colored ciliary body tumor. The growth of medulloepithelioma is slow and it is locally invasive. Poor vision and pain are the most common presenting symptoms. The most common clinical signs include cyst or mass in iris, anterior chamber or ciliary body, glaucoma, and cataract. Case: A 22-month-old Caucasian female twin presented with leukocoria and poor vision in OS. Examination revealed normal findings OD and a mass in OS. Based on the clinical features of leukocoria, lens changes and a white cystic ciliary body mass in a young child, ultrasonographic, and transillumination features, the lesion was diagnosed as a non-pigmented ciliary epithelial medulloepithelioma. After enucleation, the diagnosis of malignant teratoid medulloepithelioma of the non-pigmented ciliary epithelium was confirmed. There was no evidence of tumor recurrence or systemic metastasis at three years follow-up. Conclusion: Medulloepithelioma in a child can present as a clinical triad of leukocoria, lens changes, and a white cystic ciliary body mass.

    The purpose of this study is to evaluate the CT findings and clinical features of patients with pneumatosis intestinalis. From January 2001 to October 2007, 15 patients with pneumatosis intestinalis were diagnosed by the use of CT. We analyzed the clinical features and CT findings to assess the involvement site, the presence of portal and mesenteric vein gas, and the existence of accompanied ischemic change. Of the 15 patients, five patients had end stage renal disease (33.3%), two patients underwent a gastrectomy, one patient underwent a laminectomy, one patient had tuberculous enteritis, one patient had lung cancer and one patient had pneumonia. Four patients presented with no specific disease. There was portal or mesenteric venous gas in six cases, and strangulation or an ischemic change of the bowel in five cases. Otherwise, pneumatosis intestinalis was associated with hydropneumoperitoneum in two cases, pneumoperitoneum in one case and a single case of perforated appendicitis. Nine patients underwent surgery for ischemic change of the bowel, pneumoperitoneum, appendicitis, and a clinical sign of panperitonitis. Among the remaining six patients, three patients recovered and were discharged, and three patients expired during progression of the disease. End stage renal disease is the most common condition associated with pneumatosis intestinalis. The presence of portomesenteric venous gas, ischemic change of the bowel, and linear pneumatosis intestinalis are indicative of a poor prognosis.

    The term ‘neuromyelitis optica’ (‘Devic's syndrome’, NMO) refers to a syndrome characterized by optic neuritis and myelitis. In recent years, the condition has raised enormous interest among scientists and clinical neurologists, fuelled by the detection of a specific serum immunoglobulin (Ig)G reactivity (NMO-IgG) in up to 80% of patients with NMO. These autoantibodies were later shown to target aquaporin-4 (AQP4), the most abundant water channel in the central nervous system (CNS). Here we give an up-to-date overview of the clinical and paraclinical features, immunopathogenesis and treatment of NMO. We discuss the widening clinical spectrum of AQP4-related autoimmunity, the role of magnetic resonance imaging (MRI) and new diagnostic means such as optical coherence tomography in the diagnosis of NMO, the role of NMO-IgG, T cells and granulocytes in the pathophysiology of NMO, and outline prospects for new and emerging therapies for this rare, but often devastating condition.

    In this review, we delineate clinical, electrodiagnostic, and radiographic features of ulnar mononeuropathies. Ulnar neuropathy at the elbow (UNE) is most commonly due to lesions at the level of the retroepicondylar groove (RTC), with approximately 25% at the humeroulnar arcade (HUA). The term 'cubital tunnel syndrome' should be reserved for the latter. The diagnostic accuracy of nerve conduction studies is limited by biological (e.g. low elbow temperature) and technical factors. Across-elbow distance measurements greater than 10 cm improve diagnostic specificity at the expense of decreased sensitivity. Short-segment incremental studies can differentiate lesions at the HUA from those at the RTC.

    Objective: To establish the initial symptoms and physical signs of osteosarcoma from the records of the first medical visit and to identify early characteristics of the diseases to shorten the delay of diagnosis. Methods: A group of patients with osteosarcoma in extremities was identified from Nanjing Jinling Hospital. Records from the first medical visit due to symptoms and physical signs related to the bone tumor were obtained from 71 patients with osteosarcoma. Results: The results of the data recorded about the first medical visit,reasons for consultation, pain,trauma,initial diagnosis,delay in diagnosis were reported respectively. Conclusion: Pair an initial symptom of osteosarcoma, and was intermittent but not frequently felt at night. A history of trauma was common, but the clinical course often diverged from what was expected from trauma. The most important clinical feature was a palpable mass. This finding emphasizes that a thorough physical examination is absolutely necessary.

    Objective To explore prospective diagnostic criteria for preleukemia.Methods A case control study was done comparing the discrepancies on clinical and laboratory features between patients with preleukemia and those with chronic aplastic anemia (CAA) or atypical paroxysmal nocturnal hemoglubinuria (a-PNH).Results There were eight variables of significance: (1) lymphocytoid micromegakaryocytes in the bone marrow; (2) immature granulocytes in the peripheral blood; (3) ≥2.0% myeloblasts in the bone marrow; (4) positive periodic acid schiff (PAS) stained nucleated erythrocytes; (5) myeloid differentiation index ≥1.8; (6) typical colonal karyotypic abnormalities; (7) negative sister chromatid differentiation; (8) cluster/colony ratio of granulocyte-macrophage colony-forming units (CFU-GM)>4.0. The following criteria were assigned: A: to meet variable one and at least two of the other seven variables and B: to meet at least four of the eight variables. All of the patients with preleukemia met either A or B and none of the patients with CAA or a-PNH did. Conclusions Preleukemia is different from CAA or a-PNH. It has its own clinical and laboratory features, which may be useful for its prospective diagnosis.

    Autoimmune uveitis (AU), an inflammatory non-infectious process of the vascular layer of the eye, can lead to visual impairment and, in the absence of a timely diagnosis and suitable therapy, can even result in total blindness. The majority of AU cases are idiopathic, whereas fewer than 20 % are associated with systemic diseases. The clinical severity of AU depends on whether the anterior, intermediate, or posterior part of the uvea is involved and may range from almost asymptomatic to rapidly sight-threatening forms. Race, genetic background, and environmental factors can also influence the clinical picture. The pathogenetic mechanism of AU is still poorly defined, given its remarkable heterogeneity and the many discrepancies between experimental and human uveitis. Even so, the onset of AU is thought to be related to an aberrant T cell-mediated immune response, triggered by inflammation and directed against retinal or cross-reactive antigens. B cells may also play a role in uveal antigen presentation and in the subsequent activation of T cells. The management of AU remains a challenge for clinicians, especially because of the paucity of randomized clinical trials that have systematically evaluated the effectiveness of different drugs. In addition to topical treatment, several different therapeutic options are available, although a standardized regimen is thus far lacking. Current guidelines recommend corticosteroids as the first-line therapy for patients with active AU. Immunosuppressive drugs may be subsequently required to treat steroid-resistant AU and for steroid-sparing purposes. The recent introduction of biological agents, such as those targeting tumor necrosis factor-α, is expected to remarkably increase the percentages of responders and to prevent irreversible sight impairment. This paper reviews the clinical features of AU and its crucial pathogenetic targets in relation to the current therapeutic perspectives. Also, the largest clinical trials

    Pachyonychia congenita (PC) is a rare genodermatosis affecting the nails, skin, oral mucosae, larynx, hair, and teeth. Pathogenic mutations in keratins K6a or K16 are associated with the PC-1 phenotype whereas K6b and K17 mutations are associated with the PC-2 phenotype. Analysis of clinical, pathological, and genetic data from the literature and two research registries reveal that >97% of PC cases exhibit fingernail and toenail thickening, and painful plantar keratoderma. Prospective evaluation of 57 PC patients from 41 families revealed variable clinical findings: hyperhidrosis (79%), oral leukokeratosis (75%), follicular keratosis (65%), palmar keratoderma (60%), cutaneous cysts (35%), hoarseness or laryngeal involvement (16%), coarse or twisted hair (26%), early primary tooth loss (14%), and presence of natal or prenatal teeth (2%). Stratification of these data by keratin mutation confirmed the increased incidence of cyst formation and natal teeth among PC-2 patients, although cysts were more commonly seen in PC-1 than previously reported (25%-33%). Previously unreported clinical features of PC include development of painful oral and nipple lesions during breastfeeding, copious production of waxy material in ears, and inability to walk without an ambulatory aid (50%). Possible pathogenic mechanisms are discussed with respect to the clinicopathologic and genetic correlations observed.

    A few authors have described the clinical picture of dysthymia in groups of elderly patients and pointed out differences from literature reports of dysthymia in younger adults. The present study, an attempt to analyze age effects on clinical characteristics of dysthymia throughout a lifetime, was performed in a sample of 106 patients, all aged > or =18 years, who were diagnosed according to DSM-IV. The patients were evaluated using: (1) a semistructured interview to assess clinical features, family history and previous treatments; (2) the Hamilton Depression Rating Scale; (3) the Interview for Recent Life Events; and (4) the Structured Clinical Interview for DSM-IV Disorders. Statistical analysis with stepwise logistic regression revealed that age was positively related to concomitant medical illnesses and to the total score of recent life events, but negatively related to the presence of avoidant or dependent personality disorders. The data suggested different etiologic pathways in older and younger patients. Dysthymia appeared to be associated in younger adults with abnormalities of personality; in the elderly, with a history of health problems and life losses.

    Objective To investigate the clinical pathological feature and diagnostic criteria of tongue amyloidosis (AL).Methods During 1992 to 2005, 25 patients pathologically diagnosed as tongue AL in our hospital were reviewed retrospectively, and all of them had no enlarged tongue. Haematoxylin and eosin (HE) and immunohistochemical staining were used to detect the amyloid deposition on the tongue.Results Totally 84 % (21/25) patients had symptoms of xerostomia and taste-blindness, 44 % (11/25) patients complained of activity limitation of tongue. Macroscopic observation showed mucosa pallescence, punctuate hemorrhage, red grain particles, and ulcers on the tongue. HE staining indicated amyloid depositions in basement membrane,muscle cell, vessel wall, and nerve fiber. Immunohistochemical study demonstrated kappa light-chain deposition in 64%(16/25) cases, and lambda light-chain deposition in 36 % (9/25) cases. They presented in vessel wall, nerve fiber, and muscle cells.Conclusion The biopsy is an important means for the diagnosis of early tongue AL, and the wide variety of amyloid light chain is helpful to differential diagnosis.

    We aimed to describe clinical and diagnostic features of vertebral osteomyelitis for differential diagnosis and treatment. This is a prospective observational study performed between 2002 and 2012 in Ankara Numune Education and Research Hospital in Ankara, Turkey. All the patients with vertebral osteomyelitis were followed for from 6 months to 3 years. In total, 214 patients were included in the study, 113 out of 214 (53%) were female. Out of 214 patients, 96 (45%) had brucellar vertebral osteomyelitis (BVO), 63 (29%) had tuberculous vertebral osteomyelitis (TVO), and 55 (26%) had pyogenic vertebral osteomyelitis (PVO). Mean number of days between onset of symptoms and establishment of diagnosis was greater with the patients with TVO (266 days) than BVO (115 days) or PVO (151 days, p 15 mm, sensitivity was 0.66, specificity was 0.97, positive predictive value was 0.89, negative predictive value was 0.88, and receiver operating characteristics area was 0.8. Tuberculous and brucellar vertebral osteomyelitis remained the leading causes of vertebral osteomyelitis with delayed diagnosis. In differential diagnosis of vertebral osteomyelitis, consumption of unpasteurized cheese, dealing with husbandry, sweating, arthralgia, hepatomegaly, elevated alanine transaminase, and lumbar involvement in magnetic resonance imaging were found to be predictors of BVO, thoracic involvement in magnetic resonance imaging and tuberculin skin test > 15 mm were found to be predictors of TVO, and history of spinal surgery and leucocytosis were found to be predictors of PVO.

    Full Text Available Departing from the polyvalent metaphor of the “clinic,” this article discusses the results of the first phase of an English teacher education project, part of the Teaching Initiation Scholarship Program (PIBID/CAPES at a federal university in Brazil. Given the effects of globalization on language teaching and learning, the English teacher certification program needs to incorporate critical and intercultural perspectives in the reflexive dimension of the teacher education curriculum. One possible approach is the study of global English, or Anglophone, literatures utilizing a cultural studies and postcolonial theoretical framework. In accordance with recent observations by Festino (2011 and Lourenço (2011 about the importance of literatures in English for education in Brazil, I propose a multimodal and critical approach to the study of Anglophone literatures connected to teaching in basic education that also stimulates teacher reflection. This approach also seeks to illuminatethe role of English in Brazil and clarify the notion of content in English classes, as it relates to narrative. My analysis involves a triptych of literary genres from different countries: Kendal Hippolyte (poetry – St. Lucia, Chinua Achebe (novel – Nigeria, and Jhumpa Lahiri (short story – United States and India. Some strategies for transposing literary studies to the middle school English classroom in Brazil are also outlined.

    have electrolyte disturbances like hyponatremia, hypokalemia, and metabolic alkalosis, associated with defective water handling or with diuretic use. Serum aminotransferases, alkaline phosphatase and gammaglutamyl transpeptidase are often abnormal in a nonspecific pattern. Some serum markers are useful in diagnosis of HCC. The most commonly used is alpha-fetoprotein (AFP. AFP is a glycoprotein that is normally produced during gestation by the fetal liver and the yolk sac.

    In adults, normal values are less than 20 ng/ml and AFP is often elevated in patients with HCC. Serum concentrations of AFP do not correlate with clinical features of HCC, such as size, stage and prognosis but is generally accepted that serum levels greater than 500 ng/ml in a high risk patient is diagnosis of HCC.

    Other serum markers - Because of the limitations of serum AFP measurements, other serum markers of HCC used alone or in combination with the serum AFP have been evaluated for diagnosis or determining prognosis in patients with HCC. These include lens culinaris agglutinin-reactive AFP and des-gamma carboxyprothrombin, glypican-3, human hepatocyte growth factor, and insulin-like growth factor.

    Autoimmune hepatitis (AIH) is a chronic hepatitis of unknown etiology which can progress to cirrhosis.Its clinical manifestations are highly variable and sometimes follow a fluctuating course.Diagnosis is based on characteristic histologic,clinical,biochemical and serological findings. Anti-inflammatory/immunosuppressive treatment frequently induces remission but long-term maintenance therapy is often required. Liver transplantation is generally successful in patients with decompensated cirrhosis unresponsive to or intolerant of medical therapy.

    2015-11-01

    Cachexia is a clinically relevant syndrome which impacts on quality of life, morbidity and mortality of patients suffering from acute and chronic diseases. The hallmark of cachexia is muscle loss, which is triggered by disease-associated inflammatory response. Cachexia is a continuum and therefore a staging system is needed. Initially, a three-stage system (i.e. pre-cachexia, cachexia and refractory cachexia) was proposed. More recent evidence supports the use of a five-stage classification system, based on patient's BMI and severity of weight loss, to better predict clinical outcome. Also, large clinical trials in cancer patients demonstrated that cachexia emerging during chemotherapy has greater influence on survival than weight loss at baseline. Therefore, becoming widely accepted is the importance of routinely monitoring patients' nutritional status to detect early changes and diagnose cachexia in its early phases. Although cachexia is associated with the presence of anabolic resistance, it has been shown that sustained yet physiological hyperaminoacidaemia, as well as the use of specific nutrients, is able to overcome impaired protein synthesis and revert catabolism. More importantly, clinical evidence demonstrates that preservation of nutritional status during chemotherapy or improvement of body weight after weight loss is associated with longer survival in cancer patients.

    Palheta Neto, Francisco Xavier

    2008-12-01

    Full Text Available Introduction: The Syndrome of Sturge-Weber is a rare condition of congenital development, and is characterized by a neurocutaneous disorder with angiomas wrapping the leptomeninges and the face skin, mainly in the course of ophthalmic (V1 and maxillary (V2 branches of the trigeminal nerve. Objective: To review the literature about the Sturge-Weber Syndrome with emphasis on the current aspects. Method: The following databases were searched: EMedicine, Encyclopedia of Medicine, FindArticles, LILACS, MEDLINE, Merck Manuals On-Line Medical Library and Scielo, and the searches applied the terms: Sturge-Weber Syndrome, neurocutaneous syndromes, encephalo-trigeminal angiomatosis, nevus flammeus, in articles published between 1991 and 2007. Literature's Review: The most characteristic clinical statement is the presence, since the birth, of nevus flammeus, that generally reaches one half of the face and may stretch out up to the neck; in addition, other clinical manifestations may be present, like the corticocerebral angiomatosis, cerebral calcifications, epilepsy, ocular and buccal affections and mental retardation. The diagnosis is established by means of the inquiry of neurological and ophthalmic alterations in patients with a characteristic nevus flammeus, allied to the clinical data of complementary exams such as Computerized Tomography. The treatment consists basically of controlling the already confirmed clinical manifestations and preventing from the appearing of other alterations, mainly buccal and ocular. Conclusion: This syndrome is not much frequent, but it needs to be early diagnosed, since it brings a series of complications to its carriers when not treated, specially because of reaching the Nervous Central System. The health professionals have to be suitably able to recognize its characteristic signs and symptoms, and so improve the quality of life of these patients.

    Objective:To analyze the clinicopathological features and differential diagnosis of angiomyofibroblastoma(AMFB) of the vulva. Methods:Two cases of AMFB were examined by light microscopy and immunohistochemical study and to discuss the clinicopatholoical features and differential diagnosis of AMFB with the reference to the literature. Results:Tumors were all circumscribed,and<5 cm in diameter.Microscopically,the tumors were composed of spindle or polygonal cells that were cellularly or hypocellularly arranged with perivascular accentuation in a mucoid or fibrocollagenous background.The tumors contained numerous small-to medium-sized blood vessels,which were characteristically thin walled.Immunohistochemically,two cases of tumor cells were positive for vimentin,SMA,CD34(+)and FⅧ(+). Desmin and MSA were positive in one case:Cytokeratin,S-100,CD31 were negative in both. Conclusion:AMFB is a rare,benign soft tissue tumor that occurs in the genital tract of adult women.The origin remains unclear,but it is suggested that an origin from a perivascular pluripotent stem cell that is capable of myofibroblastoma differentiation.Angiomyofibroblastoma should be differentiated from other neoplasms of the vulva such as aggressive angiomyxoma, superficial angiomyxoma and cellular angiofibroma.

    Mucormycosis (MCM) is a life-threatening infection that carries high mortality rates despite recent advances in its diagnosis and treatment. The objective was to report 14 cases of mucormycosis infection and review the relevant literature. We retrospectively analyzed the demographic and clinical data of 14 consecutive patients that presented with MCM in a tertiary-care teaching hospital in northern Mexico. The mean age of the patients was 39.9 (range 5–65). Nine of the patients were male. Ten patients had diabetes mellitus as the underlying disease, and 6 patients had a hematological malignancy (acute leukemia). Of the diabetic patients, 3 had chronic renal failure and 4 presented with diabetic ketoacidosis. All patients had rhinocerebral involvement. In-hospital mortality was 50%. All patients received medical therapy with polyene antifungals and 11 patients underwent surgical therapy. Survivors were significantly younger and less likely to have diabetes than nonsurvivors, and had higher levels of serum albumin on admission. The clinical outcome of patients with MCM is poor. Uncontrolled diabetes and age are negative prognostic factors. PMID:25210515

    To evaluate the clinical presentations, radiological characteristics, and natural history of healthy adolescents presenting with idiopathic spontaneous pneumomediastinum. We retrospectively reviewed the simple radiographs of 14 consecutive patients (11 males) with spontaneous pneumomediastinum, who were examined over a period of 8 years, and analyzed their clinical history, radiographic findings including distribution, combined subcutaneous emphysema, mediastinal widening, pneumothorax, pleural effusion, and resolving period on follow up chest radiographs. We also obtained CT images of 7 patients for the assessment of additional information. The most common complaint at the time of presentation was chest pain and chest discomfort (8/14), followed by neck discomfort (6/14). The chest radiograph was of diagnostic value in alI cases. The main distribution of the pneumomediastinum was cervical (14/14), upper lung (13/14) and lower lung (6/14). Combined subcutaneous emphysema was observed in 6 patients. However, there were no cases of mediastinal widening, pneumothorax or pleural effusion. Complete resolution of the pneumomediastinum on the radiograph was observed after 10 days (mean 5.6), following purely conservative treatment. There was no additional information on the CT images, as compared with that on the radiographs. Idiopathic spontaneous pneumomediastinum is a benign entity that usually goes undiagnosed, but which responds very weIl to conservative treatment.

    Objective: To analyze the mechanism of diffuse axonal injury (DAI) and study the relationship between DAI and brain concussion, brain contusion, and primary brain stem injury.Methods: The clinical data and iconographic characteristics of 56 patients with DAI were analyzed retrospectively.Results: Traffic accidents were the main cause of DAI. Among the 56 cases, 34 were injured for at least twice, and 71.43% of the patients were complicated with contusion.Conclusions: It is considered that DAI is a common pattern of primary brain injury, which is often underestimated. And DAI includes cerebral concussion and primary brain injury, and is often complicated by cerebral cortex contusion. Therefore, it is very simple and practical to divide primary brain injuries into local and diffuse injuries.

    Full Text Available Fascioliasis is a worldwide but unevenly distributed zoonosis caused by the trematode Fasciola hepatica that infects do­mesti­cated herbivores. Fasciolosis also occurs accidentally in humans by ingestion of metacercaria-laden freshwater or water plants. Human infections are common in developing countries and are not rare in Europe. The clinical course has been con­ventionally described in two phases: an acute phase of hepatic parenchymal invasion of an immature worm larva (parenchy­mal phase and a stationary phase after residence in the bile duct and production of eggs (ductal phase. We report a 34 years old woman from Ilam, western Iran with hepatic disorder, RUQ pain, and jaundice. The diagnosis was made by sonography, CT scan and serologic studies. Serologic exam (ELISA was positive & CT findings were compatible with fascioliasis.

    1989-01-01

    Malignant hyperthermia (MH) is a pharmacogenetic disorder. It is classically described as a hypermetabolic state triggered by halogenated anaesthetics and/or depolarizing muscle relaxants. In fact, since Denborough and Lovel's case, it has been shown that MH has a great number of clinical forms. The overwhelming picture of muscular hypercatabolism with fulminating hyperthermia and generalized rigidity is becoming rare. A better knowledge of the first symptoms explains in part the better prognosis: masseter spasm after suxamethonium, an increase in expired CO2 concentration, unexplained tachycardia, ventricular arrhythmias. The use of dantrolene reduced the mortality of MH. The different types of clinical manifestations are due to genetic differences, the concentration of the anaesthetic agent, and the length of time of exposure to the drug. The severity of the episode is linked to environmental factors such as stress, physical exercise, ambient temperature, concomitant use of other drugs. Masseter spasm after suxamethonium is specific for MH, but not pathognomonic. It occurs in 1% of cases in children when using halothane with suxamethonium. However, in those patients who displayed such a spasm, more than 50% had a positive contracture test. Masseter spasm is often associated with severe rhabdomyolysis in patients with muscle dystrophy, especially Duchenne's dystrophy. In the latter case, major cardiac problems may occur at the time of anaesthetic induction. Even if there are no other signs of MH, all patients who have had a masseter spasm must be considered as open to doubt, and should be further explored. MH is often difficult to diagnose in medium severity types.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Tegumentary and visceral leishmaniasis are severe and unfortunately common parasitic diseases in Brazil. Among domestic animals, dogs are considered the main urban reservoir of the protozoan parasites, however, there is evidence that infected cats can also contribute towards the disease pool. The number of cats diagnosed with leishmaniasis has greatly increased in the last few years, highlighting the importance of thorough investigations on the role of the cat in the epidemiological cycle of the disease and in public health related issues. The main clinical manifestations of leishmaniasis suffered by cats, even when infected with Leishmania chagasi, a viscerotropic species, are skin abnormalities, which can be confounded with multiple other diseases. Indirect ELISA should be used as a screening test in epidemiological investigations for being a sensitive technique, followed by more specific laboratory tests. The standardization and validation of rapid, economical and reproducible diagnostic methods, to be employed in epidemiological surveillance, are still required

    Full Text Available Although the epidemiological data is generally obtained from the patients that applied for gender reassignment surgery, it is known that transsexualism is not seen as rarely as it was estimated in the past and should be evaluated in detail because of its psychological and social consequences. Etiology remains to be unclear and biological and psychosocial factors are thought to be responsible for its development. Gender identity stabilizes approximately in 3-4 ages and it is impossible to change it after these ages. For this reason the aim of treatment approaches is to improve the conformity of individuals to their identity and life, but not to change the gender identity. The World Professional Association for Transgender Health [WPATH] published a guideline including standards of care [SOC] and SOC provide clinical guidance in follow-up and treatment of transsexual individuals. There is a detailed code in civil law about gender reassignment but when this code implemented strictly, the use of it is very limited and it is clear that a new arrangement is needed in this issue.

  16. [Oral candidiasis: clinical features and control].

    Candidiasis is the most commonly encountered fungal infection, and oral candidiasis is often observed as a local opportunistic infection. Oral candidiasis is clinically divided into three types: acute forms, chronic forms, and Candida-associated lesions. Candida adhesion and multiplication are largely regulated by the local and systemic factors of the host. The local factors include impairment of the oral mucosal integrity, which is usually impaired by hyposalivation, anticancer drugs/radiation for head and neck cancers, denture wearing, a decrease in the oral bacterial population, and poor oral hygiene. Among Candida species, oral candidiasis is mostly caused by Candida albicans (C. albicans), C. glabrata, or C. tropicalis. Oral Candida induces a variety of symptoms, such as oral mucosal inflammation manifesting as an uncomfortable feeling, pain, erythema, erosion, taste abnormalities, and hyperplasia of the oral mucosa. Candida overgrowth in the oral cavity may disseminate to distant organs. Therefore, in order to avoid the sequelae of systemic candidiasis, oral candidiasis should be rapidly controlled. Oral candidiasis is usually treated by the local application of antifungal drugs. However, oral candidiasis occasionally escapes the control of such local treatment due to the development of multi-drug resistant Candida strains and species or due to the suppression of salivation or cellular immune activity. When drug-resistant strains are suspected as the pathogens and when the host is generally compromised, the oral administration of combinations of antifungal drugs, enhancement of cellular immune activity, and improvement of the nutritional condition are recommended.

    The term "functional food" refers to foods or ingredients of foods providing an additional physiological benefit beyond their basic nutritional needs. Health benefits are best obtained through a varied diet containing fruits, vegetables, grains, legumes and seeds. However, fortified foods and dietary supplements have been marketed and food industry have made functional food one of their current leading trends. Recently, the number of functional foods that have a potential benefit on health has hugely grown and scientific evidence is supporting the role of functional foods in prevention and treatment of several diseases. Cancer, diabetes, heart disease and hypertension are the most important diseases that can be treated or prevented by functional foods; other diseases are osteoporosis, abnormal bowel motility, and arthritis. It has been estimated that 80% of cancer in USA have a nutrition/diet component suggesting a great impact of functional food and foods components on incidence and treatment of cancer. Numerous factors complicate the evaluation of scientific evidence such as the complexity of food substance, effect on food, metabolic changes associated to dietary changes, the lack of biological markers of disease development. This paper reviews the scientific evidence supporting this area regarding only those foods and ingredients in which a clear experimental and clinical evidence exists for their chemopreventive and therapeutic effects.

They are the most common benign tumors in childhood. Recently, there have been significant, exciting advancements in the understanding of the pathogenesis and treatment of infantile hemangiomas, which are discussed in this review. The decision to initiate treatment for IH is based on many factors, including size and location, functional compromise, psychosocial implications, and risks and benefits of the proposed therapy. For most families of children with hemangiomas, education about the natural history of IH and reassurance are often the only "treatment" required. A minority of patients with large, complex lesions or lesions that cause functional compromise require early intervention. These patients and families benefit from a multidisciplinary approach to care in vascular birthmark centers. Ongoing multi-institutional clinical trials will provide further important data on the efficacy and safety of hemangioma treatments.Keywords: progenitor stem cell, glucose transporter 1, PHACES, LUMBAR, infantile hemangioma

    Full Text Available [u][/u] Narcolepsy is a chronic hypersomnia characterized by excessive daytime sleepiness (EDS and manifestations of disrupted rapid eye movement sleep stage (cataplexy, sleep paralysis, and hypnagogic/hypnopompic hallucinations. Mechanisms underlying narcolepsy are not fully understood. Experimental data indicate that the disease is caused by a loss of hypocretin neurons in the hypothalamus, likely due to an autoimmune process triggered by environmental factors in susceptible individuals. Most patients with narcolepsy and cataplexy have very low hypocretin-1 levels in the cerebrospinal fluid. An appropriate clinical history, polysomnogram, and multiple sleep latency test are necessary for diagnosis of the disease. Additionally, two biological markers, i.e., cerebrospinal fluid hypocretin-1 levels and expression of the DQB1*0602 gene, are used. The treatment of narcolepsy is aimed at the different symptoms that the patient manifests. Excessive daytime sleepiness is treated with psychostimulants (amphetamine-like, modafinil and armodafinil. Cataplexy is treated with sodium oxybate (GHB, tricyclic antidepressants, or selective serotonin and noradrenaline reuptake inhibitors. Sleep paralysis, hallucinations, and fragmented sleep may be treated with sodium oxybate. Patients with narcolepsy should follow proper sleep hygiene and avoid strong emotions.

    To evaluate types of gray matter heterotopias, associated brain anomalies, and its correlation with the patterns of seizure. We evaluated retrospectively 19 patients (male:female=10:9, mean age 21 years) with gray matter heterotopias on brain MRI. Using 1.0T superconducting MR unit, spin echo T1-, proton -density and T2-weighted images in axial, coronal and sagittal planes were obtained. Types of gray matter heterotopias were single subependymal in four patients, multiple subependymal in one, focal subcortical in eight, diffuse subcortical in two, mixed multiple subependymal and focal subcortical in four. Associated anomalies were seen in 11 patients: other neuronal migration anomalies in eight patients, corpus callosum agenesis in two, and combined holoprosencephaly and Dandy-Walker malformation in one. Fifteen patients had seizure. The patterns of seizure were not correlated with the types of heterotopias. In addition to subependymal, focal subcortical, and diffuse subcortical types, gray matter heterotopias included mixed variant of multiple subependymal and subcortical type. Schizencephaly was the most common form of accompanying anomalies, and patterns of seizure were not correlated with types of gray matter heterotopias, even though main clinical manifestation was seizure.

    Full Text Available Parasomnias, as described in the recent second edition of the International Classification of Sleep Disorders, are “undesirable physical events or experiences” occurring during sleep transition, during arousal from sleep, or within the sleep period. These events encompass abnormal sleep related movements, behaviors, emotions, perceptions, dreaming, and autonomic nervous system functioning. Parasomnias are classified as: 1 disorders of arousal (from non-rapid eye movement, or NREM, sleep; 2 parasomnias usually associated with REM (rapid eye movement sleep; and 3 other parasomnias. This sleep disorders in childhood are common, and often more frequent than in adults. Clinicians should be aware that many pediatric parasomnias have benign and self-limited nature. Most of the parasomnias may not persist into late childhood or adolescence. Parasomnias in adults often differ in type from childhood parasomnias and may portend significant psychiatric disturbances or neurodegenerative disorders. A reliable diagnosis can often be made from a detailed history from the patient and, if possible, the parents or bed partner. Detailed overnight investigations of parasomnias are usually not required. The non-REM parasomnias are more common in community although REM parasomnias are more likely to be seen in general neurological practice. Sleep related eating disorder, sleep related dissociative disorders and sleep related sexual behavior and sleep related violence are novel and rarely reported sleep disorders. REM sleep behavior disorder is common and should be sought in all neurodegenerative diseases. They are included among clinical disorders due to the resulting injuries, and adverse health and psychosocial effects, which may affect the bed partner as well as the patient. Finally, parasomnias are common disturbances of sleep that may significantly affect the patient’s quality of life and that of the bed partner. Therefore, appropriate diagnostic and

    Full Text Available Children regularly and voluntarily go to school in order to fulfill the expectations of society from them to continue their education or schooling. School continuation has been made compulsory by laws. Nonetheless, contrary to popular belief, for some children it is distressing to go to school. These children have difficulty continuing school and/or refuse to go to school. Today school refusal is defined as a child’s inability to continue school for reasons, such as anxiety and depression. The prevalence of school refusal has been reported to be approximately 1% in school-age children and 5% in child psychiatry samples. The prevalence of school refusal is similar among boys and girls. School refusal can occur at any time throughout the child’s academic life and at all socio-economic levels. School refusal is considered a symptom rather than a clinical diagnosis and can manifest itself as a sign of many psychiatric disorders, with anxiety disorders predominant. Separation anxiety disorder, generalized anxiety disorder, social phobia, specific phobia, and adjustment disorder with anxiety symptoms are the most common disorders co-occurring with school refusal. While separation anxiety disorder is associated with school refusal in younger children, other anxiety disorders, especially phobias, are associated with school refusal in adolescents. Children who have parents with psychiatric disorders have a higher incidence of school refusal, and psychiatric disorders are more frequently seen in adult relatives of children with school refusal, which supports a significant role of genetic and environmental factors in th etiology of school refusal. School refusal is a emergency state for child mental health. As it leads to detrimental effects in the short term and the long term, it should be regarded as a serious problem. The long-lasting follow-up studies of school refusing children have revealed that these children have a higher incidence of

    Full Text Available INTRODUCTION: Strongyloides stercoralis is a soil-transmitted helminth that produces an infection that can persist for decades. The relationships between certain clinical conditions and strongyloidiasis remains controversial. This study aims to identify the clinical conditions associated with intestinal strongyloidiasis at a reference center for infectious diseases in Rio de Janeiro, Brazil. METHODS: The clinical conditions that were assessed included HIV/AIDS, HTLV infection, cardiovascular diseases, diabetes, obstructive respiratory diseases, viral hepatitis, tuberculosis, cancer, chronic renal disease, nutritional/metabolic disorders, psychiatric conditions, rheumatic diseases and dermatologic diseases. We compared 167 S. stercoralis-positive and 133 S. stercoralis-negative patients. RESULTS: After controlling for sex (male/female OR = 2.29; 95% (CI: (1.42 - 3.70, rheumatic diseases remained significantly associated with intestinal strongyloidiasis (OR: 4.96; 95% CI: 1.34-18.37 in a multiple logistic regression model. With respect to leukocyte counts, patients with strongyloidiasis presented with significantly higher relative eosinophil (10.32% ± 7.2 vs. 4.23% ± 2.92 and monocyte (8.49% ± 7.25 vs. 5.39% ± 4.31 counts and lower segmented neutrophil (52.85% ± 15.31 vs. 61.32% ± 11.4 and lymphocyte counts (28.11% ± 9.72 vs. 30.90% ± 9.51 than S. stercoralis-negative patients. CONCLUSIONS: Strongyloidiasis should be routinely investigated in hospitalized patients with complex conditions facilitate the treatment of patients who will undergo immunosuppressive therapy. Diagnoses should be determined through the use of appropriate parasitological methods, such as the Baermann-Moraes technique.

    2017-04-01

    This study investigates the relationship between political consumerism and core political values (CPVs) among university students in Brazil (N = 414) and Germany (N = 222). Despite the prerequisite to endorse values that are compatible with political consumerism, contextual features of one's immediate environment might affect overall levels of political consumerism. Our results show that political consumerism is significantly associated with higher income in Brazil (but not in Germany). After controlling for income, political consumerism was practised more frequently in Germany than in Brazil, in urban compared with rural areas, and was not dependent on gender. The urban-rural split was stronger in Brazil than in Germany. These results confirm our hypothesis that contextual features are associated with political consumerism. Furthermore, the political value Equality positively predicted political consumerism in both countries. In contrast, Traditional Morality and support of Free Enterprise negatively predicted political consumerism, although the effect sizes of these relationships were only small. These results suggest that political consumerism among university students is widespread in Germany but not in Brazil. Interestingly, regardless of its low prevalence in Brazil, political consumerism is positively associated with the CPV of Equality among university students in both countries.

    Full Text Available Differences in age and sex distribution as well as FAB (French-American-British classification types have been reported for acute leukemias in several countries. We studied the demographics and response to treatment of patients with acute myeloid leukemia (AML and acute lymphoblastic leukemia (ALL between 1989 and 2000 in Teresina, Piauí, and compared these results with reports from Brazil and other countries. Complete data concerning 345 patients (230 ALL, 115 AML were reviewed. AML occurred predominantly in adults (77%, with a median age of 34 years, similar to that found in the southeast of Brazil but lower than the median age in the United States and Europe (52 years. FAB distribution was similar in children and adults and FAB-M2 was the most common type, as also found in Japan. The high frequency of FAB-M3 described in most Brazilian studies and for Hispanics in the United States was not observed. Overall survival for adults was 40%, similar to other studies in Brazil. A high mortality rate was observed during induction. No clinical or hematological parameter influenced survival in the Cox model. ALL presented the characteristic peak of incidence between 2-8 years. Most of the cases were CD10+ pre-B ALL. In 25%, abnormal expression of myeloid antigens was observed. Only 10% of the patients were older than 30 years. Overall survival was better for children. Age and leukocyte count were independent prognostic factors. These data demonstrate that, although there are regional peculiarities, the application of standardized treatments and good supportive care make it possible to achieve results observed in other countries for the same chemotherapy protocols.

    Burkitt lymphoma (BL) is a highly aggressive non-Hodgkin lymphoma with a consistent MYC translocation. Epstein-Barr virus (EBV) has been associated with BL at different frequencies, depending on the clinical variant and geographic regions. This is a large-scale study of BL in Brazil, including 234 patients from 5 geographic regions that are widely disparate socioeconomically, including pediatric (61.1%) and adult (37.6%) populations. EBV was present in 52.6% of all BL cases, varying from 29% (12/42) in the South to 76% (13/17) in the North. Most of the cases were EBV type A. The frequency was higher in the pediatric group, and EBV association within this age range predominated in all regions except the South. Expression of p53 protein was observed in 16.2%, and only rare cases showed p63 expression. BL in Brazil is regionally distinct and has a low incidence of p53 overexpression and a higher-than-expected association with EBV in sporadic cases.

    Full Text Available ABSTRACT INTRODUCTION: Despite being the most prevalent arboviral disease worldwide, dengue has been neglected lately. However, recent epidemics of arboviruses such as Zika and chikungunya in locations throughout the world have alerted health authorities to these diseases. This study evaluated the incidence pattern of dengue, its clinical characteristics, and co-circulation of serotypes from 2007 to 2015 in Paraiba State, Northeast Brazil. METHODS: Data on dengue cases from 2007 to 2015 were extracted from clinical reports of the National System for Notifiable Diseases [Sistema Nacional de Agravos de Notificação (SINAN] of Brazil provided by the Paraiba Health Department. Reverse transcription polymerase chain reaction (RT-PCR assays for dengue serotypes were carried out on plasma samples obtained from patients with suspected dengue. The data were analysed using descriptive statistics. RESULTS: According to clinical features, dengue fever [n = 39,083 (70.2%] and dengue without warning signs [n = 15,365 (27.7%] were the most common classifications of dengue. On RT-PCR, DENV 1 was the most commonly identified serotype (80.5% in all years studied. Co-circulation of all four DENV serotypes was observed in 2013 and 2014. Furthermore, we observed an increase in dengue notifications in 2015, possibly due to the rise of Zika and chikungunya. CONCLUSIONS: Our findings support the hypothesis that co-circulation of the four DENV serotypes may be a reason for the increased prevalence of severe forms of dengue in the years studied. This study may contribute to directing research, health policy, and financial resources toward reducing poorly controlled epidemic diseases.

    The objectives were to study: (1) acceptance of STD screening in non-clinical settings for asymptomatic individuals; (2) risk factors and STD prevalence among individuals in non-clinical and clinical settings; and (3) non-clinical screening of asymptomatic populations as a feasible method for STD control. We recruited 139 males and 486 females between 18 and 30 years of age from a family planning clinic, schools, and community centers in low-income neighborhoods. We asked about STD symptoms and STD/HIV risk behaviors and tested the individuals for gonorrhea, Chlamydia, syphilis, and HIV. Except for HIV, women recruited directly from the community had higher STD rates than those who came in for care at the clinic. Screening in non-clinical settings in Brazil is feasible and has a high yield among young adults in low-income communities. Infected participants would likely never have otherwise sought care or been tested or treated. STD control efforts could be implemented in any site that can reach populations at risk and become a routine procedure in health care settings where people report for problems unrelated to STDs.

    Full Text Available Background: Chronic actinic dermatitis (CAD, one of the immune mediated photo-dermatoses, comprises a spectrum of conditions including persistent light reactivity, photosensitive eczema and actinic reticuloid. Diagnostic criteria were laid down about 20 years back, but clinical features are the mainstay in diagnosis. In addition to extreme sensitivity to UVB, UVA and/or visible light, about three quarters of patients exhibit contact sensitivity to several allergens, which may contribute to the etiopathogenesis of CAD. This study was undertaken to examine the clinical features of CAD in India and to evaluate the relevance of patch testing and photo-aggravation testing in the diagnosis of CAD. Methods: The clinical data of nine patients with CAD were analyzed. Histopathology, patch testing and photo-aggravation testing were also performed. Results: All the patients were males. The average age of onset was 57 years. The first episode was usually noticed in the beginning of summer. Later the disease gradually tended to be perennial, without any seasonal variations. The areas affected were mainly the photo-exposed areas in all patients, and the back in three patients. Erythroderma was the presenting feature in two patients. The palms and soles were involved in five patients. Patch testing was positive in seven of nine patients. Conclusions: The diagnosis of CAD mainly depended upon the history and clinical features. The incidence of erythroderma and palmoplantar eczema was high in our series. Occupation seems to play a role in the etiopathogenesis of CAD.

    Steatocystoma multiplex (SM) shares many clinical features and may show overlapping histopathological features with eruptive vellus hair cyst (EVHC). Clinical data and pathologic features of 64 patients with SM were evaluated in detail. Most of the cases were sporadic, with an average onset age of 26 years and distribution on the arms, chest, axillae, and neck. All cases exhibited eosinophilic cuticle and lack of granular layer, and 17-42% displayed vellus hair, hair follicles, keratin, and smooth muscle components within the cavity, in the wall, or adjacent to it. The results of this study add further evidence to the hypothesis that SM is a hamartomatous condition and that SM and EVHC are variants of one disorder which originates in the pilosebaceous duct.

    Morvan's Fibrillary Chorea (MFC) is a rare autoimmune disorder causally associated with auto-antibodies directed at the voltage-gated potassium channel (VGKC-Abs). It classically presents with sleep disturbances, neuromyotonia and dysautonomia. We aimed to systematically characterise the features of MFC by describing a patient and reviewing published literature. Case notes of 27 patients with MFC (one from our clinic and 26 from the literature) were reviewed and clinical data were extracted and analysed. We found that MFC mainly affects men (96%) and runs a subacute course over months. Neoplasia (56%), VGKC-Abs positivity (79%) and autoimmunity (41%) are frequent associations. Myokymia, insomnia and hyperhidrosis were almost universally described. Other autonomic features were present in 63% with the most common being cardiovascular and bowel disturbances. Clinical, radiological or electroencephalographical features of limbic encephalitis were present in 19% of patients. Outcome was fair with an overall recovery rate of 78%. All patients with malignancies underwent surgery. Immunotherapies including corticosteroids, intravenous immunoglobulins and plasma exchange were instituted in 22 patients and 19 (86%) responded. Of all symptomatic treatments tried, carbamazepine, phenytoin, sodium valproate, levetiracetam and niaprazine were found to be effective. The broad clinical spectrum of VGKC-Abs diseases can make early recognition of MFC difficult. Myokymia, insomnia and hyperhidrosis are invariably present. There may be abnormalities on cerebrospinal fluid testing and VGKC-Abs can occasionally be absent. Early initiation of immunotherapies and malignancy screening are important to prevent adverse outcomes in a condition that generally responds favourably to treatment.

    A dermatoscope is an important tool in a dermatologist's armamentarium as it can eliminate the need for a biopsy in a wide array of conditions. Porokeratosis was described by Mibelli and Respighi in 1893, as a disorder of keratinization which on the basis of distribution patterns was described as five clinical variants that portrayed a coronoid lamella on histopathology. We describe a case of asymptomatic, long-standing palmar and plantar pits, which on dermatoscopy showed features suggestive of porokeratosis, which was later reconfirmed by histopathologic sections. This report depicts diagnostic features of porokeratosis and obviates the need for invasive procedures for its diagnosis. PMID:27559506

    Full Text Available In 2015, Brazil was faced with the cocirculation of three arboviruses of major public health importance. The emergence of Zika virus (ZIKV presents new challenges to both clinicians and public health authorities. Overlapping clinical features between diseases caused by ZIKV, Dengue (DENV and Chikungunya (CHIKV and the lack of validated serological assays for ZIKV make accurate diagnosis difficult.The outpatient service for acute febrile illnesses in Fiocruz initiated a syndromic clinical observational study in 2007 to capture unusual presentations of DENV infections. In January 2015, an increase of cases with exanthematic disease was observed. Trained physicians evaluated the patients using a detailed case report form that included clinical assessment and laboratory investigations. The laboratory diagnostic algorithm included assays for detection of ZIKV, CHIKV and DENV. 364 suspected cases of Zika virus disease were identified based on clinical criteria between January and July 2015. Of these, 262 (71.9% were tested and 119 (45.4% were confirmed by the detection of ZIKV RNA. All of the samples with sequence information available clustered within the Asian genotype.This is the first report of a ZIKV outbreak in the state of Rio de Janeiro, based on a large number of suspected (n = 364 and laboratory confirmed cases (n = 119. We were able to demonstrate that ZIKV was circulating in Rio de Janeiro as early as January 2015. The peak of the outbreak was documented in May/June 2015. More than half of the patients reported headache, arthralgia, myalgia, non-purulent conjunctivitis, and lower back pain, consistent with the case definition of suspected ZIKV disease issued by the Pan American Health Organization (PAHO. However, fever, when present, was low-intensity and short-termed. In our opinion, pruritus, the second most common clinical sign presented by the confirmed cases, should be added to the PAHO case definition, while fever could be given less

    Full Text Available The aim of the study was to examine the structure of psychopathology and clinical features of depressive disorders in patients with brain oncopathology. Polymorphic mental disorders of various clinical content and severity in most cases not only are comorbid to oncological pathology of the brain, but most often are the first clinical signs of early tumors. The study was conducted using the following methods: clinical psychiatric, questionnaire Simptom Check List- 90 -Revised-SCL- 90 -R, Luscher test and mathematical processing methods. Sample included 175 patients with brain tumors with non-psychotic level of mental disorders. The peculiarities of mental disorders and psychopathological structure of nonpsychotic depressive disorders have been a clinical option of cancer debut in patients with brain tumors. We found that nonpsychotic depression is characterized by polymorphism and syndromal incompletion; this causes ambiguity of diagnoses interpretation on stages of diagnostic period. Features of depressive symptoms depending on the signs of malignancy / nonmalignancy of brain tumor were defined.

    Full Text Available BACKGROUND: Infants account for a small proportion of the overall dengue case burden in endemic countries but can be clinically more difficult to manage. The clinical and laboratory features in infants with dengue have not been extensively characterised. METHODOLOGY/PRINCIPAL FINDINGS: This prospective, cross-sectional descriptive study of infants hospitalized with dengue was conducted in Vietnam from November 2004 to December 2007. More than two-thirds of 303 infants enrolled on clinical suspicion of dengue had a serologically confirmed dengue virus (DENV infection. Almost all were primary dengue infections and 80% of the infants developed DHF/DSS. At the time of presentation and during hospitalization, the clinical signs and symptoms in infants with dengue were difficult to distinguish from those with other febrile illnesses, suggesting that in infants early laboratory confirmation could assist appropriate management. Detection of plasma NS1 antigen was found to be a sensitive marker of acute dengue in infants with primary infection, especially in the first few days of illness. CONCLUSIONS/SIGNIFICANCE: Collectively, these results provide a systematic description of the clinical features of dengue in infants and highlight the value of NS1 detection for diagnosis.

    Diagnostic uncertainty when a patient presents with melasma-like Undings can lead to suboptimal treatment and inaccurate prognostic expectations. In this study, the authors present a unique clinical feature of melasma that they term the "Fitzpatrick macule" and test its Utility in establishing diagnostic certainty. The "Fitzpatrick macule" is a confetti-like macule of regularly pigmented skin located within a larger patch of melasma hyperpigmentation. To test its diagnostic Utility, the authors compared clinical photography of known cases of melasma with common mimickers, such as poikiloderma of Civatte and solar lentiginosis, and determined the positivity rate of the Fitzpatrick macule in each scenario. Their results show that 89.1 percent of clinical photographs of melasma were positive for the presence of Fitzpatrick macules compared to 1.1 percent that were negative. In contrast, 37.5 and 56.3 percent of clinical photographs of poikiloderma of Civatte were positive and negative for Fitzpatrick macules, respectively. Solar lentiginosis showed a 5.6 percent positivity and a 77.8 percent negativity for Fitzpatrick macules. The sensitivity and specificity of Fitzpatrick macules for melasma was 99 and 83 percent, respectively. In summary, the authors report a highly sensitive and specific clinical feature of melasma. In cases of diagnostic uncertainty, the presence of Fitzpatrick macules may aid in establishing a diagnosis of melasma.

    Full Text Available Catatonia is not a usual clinical presentation of subacute sclerosing panencephalitis (SSPE, especially in the initial stages of illness. However, there is only one reported case of SSPE presenting as catatonia among children. In this report, however, there were SSPE-specific changes on EEG and the catatonia failed to respond to lorazepam. We describe a case of SSPE in a child presenting as catatonia that presented with clinical features of catatonia and did not have typical EEG findings when assessed at first contact. He responded to lorazepam and EEG changes emerged during the course of follow-up.

    Full Text Available Hereditary spastic paraplegia (HSP is a group of genetically-determined disorders characterized by progressive spasticity and weakness of lower limbs. An apparently sporadic case of adult-onset spastic paraplegia is a frequent clinical problem and a significant proportion of cases are likely to be of genetic origin. HSP is clinically divided into pure and complicated forms. The later present with a wide range of additional neurological and systemic features. To date, there are up to 60 genetic subtypes described. All modes of monogenic inheritance have been described: autosomal dominant, autosomal recessive, X-linked and mitochondrial traits. Recent advances point to abnormal axonal transport as a key mechanism leading to the degeneration of the long motor neuron axons in the central nervous system in HSP. In this review we aim to address recent advances in the field, placing emphasis on key diagnostic features that will help practicing neurologists to identify and manage these conditions.

    Research on neuro signals is challenging and significative in modern natural science. By clinical experiment, signals from three main nerves (median nerve, radial nerve and ulnar nerve) are successfully detected and recorded without any infection. Further analysis on their features under different movements, their mechanics and correlations in dominating actions are also performed. The original discovery and first-hand materials make it possible for developing practical neuro-prosthesis.

    Interstitial lung disease (ILD) is the most common extra-articular manifestations of rheumatoid arthritis (RA) in the lung. This study aimed to identify clinical features of RA-associated ILD (RA-ILD). Patients with RA were retrospectively enrolled and sub-classified as RA-ILD or RA without ILD based on high-resolution computed tomography imaging. Pulmonary function testing parameters and levels of RA-related biomarkers, tumour markers, and acute-phase proteins were compared between the two groups. Logistic regression model was used to assess the strength of association between RA-ILD and clinical features of interest. Receiver operating characteristic analysis was performed to assess potential predictive value of clinical features for detecting RA-ILD. Comparison analysis indicated that the percentage of predicted value of total lung capacity, inspiratory capacity, and diffusion capacity of the lung for carbon monoxide (DLCO) were reduced in patients with RA-ILD. Tumour markers CA15-3 and CA125 were increased in patients with RA-ILD. Logistic regression analysis revealed that decreased DLCO was related to the increased likelihood of RA-ILD (OR = 0.94, 95%CI = [0.91, 0.98]). The cut-off point at 52.95 percent of predicted value could sensitively discriminate RA patients with or without ILD. Our study suggested that DLCO value could be a useful tool for detecting ILD in patients with RA.

Material and Methods. 130 RA pts aged 16 to 80 years (mean age 52,5 years, 105 female and 25 male were examined. 55 pts had disease duration up to 1 year, 34 - between 1 and 3 years and 41 - more than 3 years. Standard clinical, laboratory and radiological examination was performed in all pts. In 43 pts with earlv RA T and В cell receptors were studied with monoclonal antibodies against CD3, CD72, CD4, CD8, CDI6. Results. The most frequent initial symptoms preceding characteristic RA picture were arthralgia (39,2%, fever (34,6% and body weight loss (24,6%. Mono- or oligoarticuiar onset with subsequent quick transformation into polyarthritis within one year revealed in 61,5% of pts was the usual feature of early RA. The most frequent false diagnoses in early RA were osteoarthritis (in 25,1%, reactive arthritis (in 24,9% and gout (in 4,6%. Male pts had longer morning stiffness, higher levels of C-reactive protein, more pronounced functional disability, T and В cell immunity activation than female. Conclusion. Understanding of essential clinical and immunologic features of early RA will allow to diagnose the disease in time.

    The purpose of this study was to analyse MR imaging features and lesion patterns as defined by compromised vascular territories, correlating them to different clinical syndromes and aetiological aspects. In a 19.8-year period, clinical records and magnetic resonance imaging (MRI) features of 55 consecutive patients suffering from spinal cord ischemia were evaluated. Aetiologies of infarcts were arteriosclerosis of the aorta and vertebral arteries (23.6 %), aortic surgery or interventional aneurysm repair (11 %) and aortic and vertebral artery dissection (11 %), and in 23.6 %, aetiology remained unclear. Infarcts occurred in 38.2 % at the cervical and thoracic level, respectively, and 49 % of patients suffered from centromedullar syndrome caused by anterior spinal artery ischemia. MRI disclosed hyperintense pencil-like lesion pattern on T2WI in 98.2 %, cord swelling in 40 %, enhancement on post-contrast T1WI in 42.9 % and always hyperintense signal on diffusion-weighted imaging (DWI) when acquired. The most common clinical feature in spinal cord ischemia is a centromedullar syndrome, and in contrast to anterior spinal artery ischemia, infarcts in the posterior spinal artery territory are rare. The exclusively cervical location of the spinal sulcal artery syndrome seems to be a likely consequence of anterior spinal artery duplication which is observed preferentially here. (orig.)

    Full Text Available To improve our understanding of sex differences in the clinical characteristics of Parkinson's Disease, we sought to examine differences in the clinical features and disease severity of men and women with early treated Parkinson's Disease (PD enrolled in a large-scale clinical trial.Analysis was performed of baseline data from the National Institutes of Health Exploratory Trials in Parkinson's Disease (NET-PD Long-term Study-1, a randomized, multi-center, double-blind, placebo-controlled study of 10 grams of oral creatine/day in individuals with early, treated PD. We compared mean age at symptom onset, age at PD diagnosis, and age at randomization between men and women using t-test statistics. Sex differences in clinical features were evaluated, including: symptoms at diagnosis (motor and symptoms at randomization (motor, non-motor, and daily functioning.1,741 participants were enrolled (62.5% male. No differences were detected in mean age at PD onset, age at PD diagnosis, age at randomization, motor symptoms, or daily functioning between men and women. Differences in non-motor symptoms were observed, with women demonstrating better performance compared to men on SCOPA-COG (Z = 5.064, p<0.0001 and Symbol Digit Modality measures (Z = 5.221, p<0.0001.Overall, men and women did not demonstrate differences in clinical motor features early in the course of PD. However, the differences observed in non-motor cognitive symptoms suggests further assessment of the influence of sex on non-motor symptoms in later stages of PD is warranted.

    Full Text Available Background. The epidemiology of atopic dermatitis (AD in Chinese outpatients is yet to be clarified. Objectives. To investigate population-based prevalence and clinical features of AD in Chinese outpatients. Methods. A multicenter cross-sectional study was conducted in outpatients with eczema or dermatitis from 39 tertiary hospitals in 15 provinces. Results. This study included 682 patients diagnosed with AD, with the mean age of 28.8±20.1 years and the median course of 5.3±6.9 years. AD patients had more severe itching (30.4% versus 13.8%, p<0.001 and clinically suspected bacterial infection (21.7% versus 16.1%, p<0.001 than those of other types of dermatitis. Older patients were more susceptible to have a history of flexion dermatitis (p<0.001, bacterial infection (p=0.005, and severe itching (p<0.001. Outpatients with clinically suspected bacterial infection had 3.53-fold increased risk of AD than those without it (p<0.001. The morbidity rate of AD in the (20–25°N region is 2.86 times higher than that in the (40–45°N region [OR (95% CI: 0.352 (0.241–0.514, p<0.001]. Conclusions. AD is characterized by unique clinical/demographic features. Bacterial infection and latitude region may have an impact on the incidence of AD in China.

    Full Text Available PURPOSE: To investigate the clinical features, clinical course of granuloma, serologic findings, treatment outcome, and probable infection sources in adult patients with ocular toxocariasis (OT. METHODS: In this retrospective cohort study, we examined 101 adult patients diagnosed clinically and serologically with OT. Serial fundus photographs and spectral domain optical coherence tomography images of all the patients were reviewed. A clinic-based case-control study on pet ownership, occupation, and raw meat ingestion history was performed to investigate the possible infection sources. RESULTS: Among the patients diagnosed clinically and serologically with OT, 69.6% showed elevated immunoglobulin E (IgE levels. Granuloma in OT involved all retinal layers and several vitreoretinal comorbidities were noted depending on the location of granuloma: posterior pole granuloma was associated with epiretinal membrane and retinal nerve fiber layer defects, whereas peripheral granuloma was associated with vitreous opacity. Intraocular migration of granuloma was observed in 15 of 93 patients (16.1%. Treatment with albendazole (400 mg twice a day for 2 weeks and corticosteroids (oral prednisolone; 0.5-1 mg/kg/day resulted in comparable outcomes to patients on corticosteroid monotherapy; however, the 6-month recurrence rate in patients treated with combined therapy (17.4% was significantly lower than that in patients treated with corticosteroid monotherapy (54.5%, P=0.045. Ingestion of raw cow liver (80.8% or meat (71.2% was significantly more common in OT patients than healthy controls. CONCLUSIONS: Our study discusses the diagnosis, treatment, and prevention strategies for OT. Evaluation of total IgE, in addition to anti-toxocara antibody, can assist in the serologic diagnosis of OT. Combined albendazole and corticosteroid therapy may reduce intraocular inflammation and recurrence. Migrating feature of granuloma is clinically important and may further suggest

    AIM: To study the dynamic computed tomography (CT) features of hepatic angiomyolipoma (AML) in patients with or without tuberous sclerosis complex (TSC). METHODS: The clinical information, CT findings and histopathological results of hepatic AML were analyzed retrospectively in 10 patients. RESULTS: Hepatic AML was prone to occur in female patients (7/10), and most of the patients (8/10) had no specific symptoms. All tumors presented as welldefined, unenveloped nodules in the liver. Six patients with sporadic hepatic AML had a solitary hepatic nodule with a definite fat component. Non-fat components of the hepatic lesions were enhanced earlier and persistently. Prominent central vessels were noted in the portal venous phase in three patients. In four patients with hepatic AML and TSC, most of the nodules were within the peripheral liver. Seven fatdeficient nodules were found with earlier contrast enhancement and rapid contrast material washout in two patients. Lymphangioleiomyomatosis was found in one patient.CONCLUSION: Imaging features of hepatic AML are characteristic. Correct diagnosis preoperatively can be made in combination with clinical features.

  2. The Clinical Features of Myositis-Associated Autoantibodies: a Review.

    The idiopathic inflammatory myopathies (IIM) are a group of autoimmune diseases traditionally defined by clinical manifestations including skeletal muscle weakness, skin rashes, elevated skeletal muscle enzymes, and neurophysiological and/or histological evidence of muscle inflammation. Patients with myositis overlap can develop other features including parenchymal lung disease, inflammatory arthritis, gastrointestinal manifestations and marked constitutional symptoms. Although patients may be diagnosed as having polymyositis (PM) or dermatomyositis (DM) under the IIM spectrum, it is quite clear that disease course between subgroups of patients is different. For example, interstitial lung disease may predominate in some, whereas cutaneous complications, cancer risk, or severe refractory myopathy may be a significant feature in others. Therefore, tools that facilitate diagnosis and indicate which patients require more detailed investigation for disease complications are invaluable in clinical practice. The expanding field of autoantibodies (autoAbs) associated with connective tissue disease (CTD)-myositis overlap has generated considerable interest over the last few years. Using an immunological diagnostic approach, this group of heterogeneous conditions can be separated into a number of distinct clinical phenotypes. Rather than diagnose a patient as simply having PM, DM or overlap CTD, we can define syndromes to differentiate disease subsets that emphasise clinical outcomes and guide management. There are now over 15 CTD-myositis overlap autoAbs found in patients with a range of clinical manifestations including interstitial pneumonia, cutaneous disease, cancer-associated myositis and autoimmune-mediated necrotising myopathy. This review describes their diagnostic utility, potential role in disease monitoring and response to treatment. In the future, routine use of these autoAb will allow a stratified approach to managing this complex set of conditions.

    Approximately 36.5% of the U.S. adults (≥ 20 years old) are obese. Obesity has been associated with type 2 diabetes mellitus, cardiovascular disease, stroke, and several types of cancer. The present study included 1788 prostate cancer patients who were treated with radical prostatectomy at the Ochsner Health System, New Orleans, Louisiana, from January, 2001 to March, 2016. The patient’s medical records were retrospectively reviewed. Body mass index (BMI), age, ethnicity (Caucasians versus African Americans), clinical stage, Gleason score, and prostate-specific antigen (PSA) levels were retrieved. The relative risk of the patients was stratified into low risk and high risk groups. Associative analyses found that BMI was associated with age, clinical stage, Gleason score, but not ethnicity, PSA levels, or the relative risk in this cohort. Age was associated with ethnicity, clinical stage, Gleason score, and PSA levels, as well as the relative risk. Ethnicity was associated with Gleason score and PSA levels as well as the relative risk, but not clinical stage. These findings suggest that obesity is associated with advanced prostate cancer with stage T3 or Gleason score ≥ 7 diseases, and age and ethnicity are important factors that are associated with the clinical features of prostate cancer patients.

    Full Text Available and lsquo;Pilonidal sinus' disease, which is most commonly seen in reproductive populations, such as young adults - mostly in males who are in their twenties - is actually a controversial disease in that there is no consensus on its many facets. It is sometimes seen as an infected abscess draining from an opening or a lesion extending to the perineum. It may also present as a draining fistula opening to skin. In terms of etiological factors, various theories (main theories being congenital and acquired have been established since it was first described, no universal understanding achieved. A long and significant post-operative care period with different lengths of recovery depending on the type of operation are quite prevalent with regards to recurrence and complication status. In order to prevent recurrence and improve the quality of life, etiological and predisposing factors as well as clinical features of sacrococcygeal pilonidal disease should be well known, a detailed differential diagnosis should be made, and a suitable and timely intervention should be performed. It was aimed here to explain the etiological factors, pathogenesis and clinical features of the disease that may present with various clinical symptoms. [Arch Clin Exp Surg 2016; 5(4.000: 228-232

    2013-04-10

    This review focuses on summarizing 2 pivotal articles in the clinical and pathophysiologic understanding of hemicrania continua (HC). The first article, a functional imaging project, identifies both the dorsal rostral pons (a region associated with the generation of migraines) and the posterior hypothalamus (a region associated with the generation of cluster and short-lasting unilateral neuralgiform headache with conjunctival injection and tearing [SUNCT]) as active during HC. The second article is a summary of the clinical features seen in a prospective cohort of HC patients that carry significant diagnostic implications. In particular, they identify a wider range of autonomic signs than what is currently included in the International Headache Society criteria (including an absence of autonomic signs in a small percentage of patients), a high frequency of migrainous features, and the presence of aggravation and/or restlessness during attacks. Wide variations in exacerbation length, frequency, pain description, and pain location (including side-switching pain) are also noted. Thus, a case is made for widening and modifying the clinical diagnostic criteria used to identify patients with HC.

    Brazil's population in 1985 was 135 million, with an annual growth rate (1982) of 2.3%. The infant mortality rate (1981) was 92/1000, and life expectancy stood at 62.8 years. 76% of the adult population was literate. Brazil is a federal republic which recognizes 5 political parties. 55% of the population is Portuguese, Italian, German, Japanese, African, or American Indian; 38% is white. Of the work force of 50 million, 35% are engaged in agriculture, 25% work in industry, and 40% are employed in services. Trade union membership totals 6 million. The agricultural sector accounts for 12% of the GDP and 40% of exports. Brazil is largely self-sufficient in terms of food. The GDP was US$218 billion in 1984, with an annual growth rate of 4%. Per capita GDP was US$1645. Brazil's power, transportation, and communications systems have improved greatly in recent years, providing a base for economic development. High inflation rates have been a persistent problem.

    Full Text Available Non-alcoholic fatty liver disease (NAFLD is a cluster of pathological liver conditions of emerging importance in overweight and obese children. NAFLD is associated with central obesity, insulin resistance, and dyslipidaemia, which are considered to be the main features of metabolic syndrome (MetS. Prevention of the adverse outcomes of NAFLD, as well as the risk of MetS, depends on the identification of genetic background and environmental factors that modulate susceptibility to these diseases. However, several lines of evidence highlight the strong correlation and co-currency of these two chronic diseases, both in children and in adults. In the present review, we provide an overview of the current clinical proofs on the link between NAFLD and MetS in children, with particular focus on all the possible overlapping features that connect them at paediatric age.

    Dacryocystitis-related orbital cellulitis is a relatively rare condition, and large case series of this clinical entity have been reported. This study was undertaken to identify a larger cohort of patients with this ailment, with the intent of defining its clinical and microbiologic features. Case logs from four institutions were reviewed to identify patients that suffered from dacryocystitis-related orbital cellulitis. A retrospective chart review was then performed to identify clinical features, management strategies, microbiologic features, and outcomes. A dedicated statistical software package was utilized to identify correlations between these variables. 13 patients (7 females, 6 males; mean age = 57.2 years, range = 7-89 years) were identified. One patient carried a diagnosis of immunosuppressive disease. All patients underwent emergent surgical drainage and received intravenous antibiotics. Primary acquired nasolacrimal duct obstruction was found to be the underlying etiology in nine cases (69.2%), whereas four patients suffered from specific causes of their obstructions. An average of 1.07 organisms/patient (standard deviation = 0.49 organisms/patient) were recovered from microbiologic cultures, and Gram-positive bacteria represented the majority of cultured organisms. All patients experienced either stable or improved vision upon discharge. The relationships between a specific etiology and the possibility of vision loss or the number of organisms cultured, between the number of organisms cultured and vision loss, and immunosuppression and vision loss or the number of organisms cultured were all not statistically significant (p > 0.05). Dacryocystitis-related orbital cellulitis most commonly occurs in adult patients who do not carry immunosuppressive diagnoses and suffer from primary obstructions. Multiple microbiologic species may cause this problem, although Gram-positive organisms are most common. With appropriate management, stable or improved vision

OBJECTIVES: To assess incidence and clinical features of snake bite cellulitis. METHODOLOGY: This present one year prospective study was conducted in the Department of Surgery, Karnataka Institute of Medical Sciences, Hubli. Out of 520 total cases of snake bites 66 patients with cellulitis changes were studied. STATISTICAL ANALYSIS: The data obtained was coded and entered in Microsoft Excel Spreadsheet. The categorical data was expressed as rates, ratios and percentages. RESULTS: Out of 520 total snake bite cases, 66 patients developed signs of cellulitis. In patients with cellulitis 49(74.24% were males and 17(25.75% were females. In patients with cellulitis, most were aged between 31 to 45 years (36.36% and 19 to 30 years (34.84.The mean age of the study population was 32.43 ± 13.75 years. Majority of the patients (74.24% had snake bite on lower limbs. Most common symptom complex noted was pain + swelling in 30(39.39% of the patients followed by pain in 9(13.6%, swelling in 6(9%, pain+swelling+fever in 4(6%, pain + discolouration in 2(3% and pain + fever in 1(1.5% of the patients. CONCLUSIONS: The present study shows high incidence of cellulitis in patients with snake bite and most common clinical feature is cellulitis is pain + swelling. So in any case of snake of snake bite we should take the proper precautionary measures to prevent cellulitis. If cellulitis has already formed, then it should be treated without delay in order to prevent limb loss, compartment syndrome, other morbidities and even death.

    In order to know the epidemiological and clinical features of trichinosis, the data of 208 patients with trichinosis from 1992 to 1994 were analysed. The results showed that these patients came from 11 districts, and acquired the infection mainly by tasting the raw pork filling for dumplings or ingesting instant-boiled pork or mutton. The incidence of trichinosis is high in winter. Young and middle-aged workers and cadres constituted the majority of the patients and the infection was more common in the males than in females. The main clinical manifestations of trichinosis were prolonged fever, general myalgia, muscle weekness and eosinophilia. Most of the patients had no gastrointestinal symptoms and skin eruption. Eyelid edema was only seen in the early stage. Serological tests were significant value in the diagnosis of trichinosis. The key measures to prevent trichinosis were that meat inspection should be strictly carried out and bad eating habit changed.

    Purpose The aim of this study was to investigate the clinical features and extraintestinal manifestations (EIMs) of Crohn disease (CD) in Korean pediatric patients. Methods The medical records of 73 children diagnosed with CD were retrospectively reviewed. Data regarding baseline demographic and clinical characteristics, including CD phenotype at diagnosis based on the Montreal classification, and clinical features and course of EIMs were investigated. Results Fifty-two (71.2%) of the patients were males. The mean age of the patients was 12.5 years. The mean follow-up period was 3.4 years. The disease location was ileal in 3 (4.1%) of the patients, colonic in 13 (17.8%), ileocolonic in 56 (76.7%). The clinical behavior was inflammatory in 62 (84.9%) of the patients, stricturing in 8 (11.0%), and penetrating in 3 (4.1%). Perianal abscesses or fistulas were found in 37 (50.7%) of the patients. EIMs observed during the study period were anal skin tag in 25 patients (34.2%), hypertransaminasemia in 20 (27.4%), peripheral arthritis in 2 (2.7%), erythema nodosum in 2 (2.7%), vulvitis in 1 (1.4%), uveitis in 1 (1.4%), and pulmonary thromboembolism in 1 (1.4%). Conclusion Perianal diseases and manifestations were present in more than half of Korean pediatric CD patients at diagnosis. Inspection of the anus should be mandatory in Korean children with suspicious CD, as perianal fistulas, abscesses, and anal skin tags may be the first clue to the diagnosis of CD. PMID:28090468

    Precise diagnosis of small round cell tumors, which include the thoracic primitive neuroectodermal tumor, is often a challenge to the clinical, oncologist, radiologist and pathologist. Different terms have been used to designate these tumors, depending on their location and extent of neural differentiation. With the progress of immuno-histochemical and cytogenetic diagnosis method, some of this tumors are now classified a unique clinical entity with several locations and mode of presentation. Therefore, tumors-like peripheral neuro epithelioma, Askin`s tumor, adult neuroblastoma, and primitive neuroectodermal tumor are now named peripheral primitive neuroectodermal tumor. The most common location of peripheral primitive neuroectodermal tumor is the thorax, and the mean age are close of the adolescence. This study reports the clinical, radiological and pathological features of 5 adults (3 men and 2 women) seen at the Hospital Heliopolis, Sao Paulo, SP Brazil, between 1991 and 1995 (5 years), with diagnosis of peripheral primitive neuroectodermal tumor made by immuno-histochemical and pathological studies. The mean age of the patients was 34 years, ranged between 17 and 57 years, and the most common location was the chest wall (n=3), followed by the posterior mediastinum (n=2). All the patients were symptomatic and undergone plain films and computed tomography. (author) 12 refs., 5 figs.

    The present study reports the first isolation of Actinobacillus seminis from a goat in Brazil. A four-year-old Moxotó breeding goat in a flock of 70 goats and 65 sheep reared together in the county of Patos, semiarid region of Northeastern Brazil, showed clinical signs of unilateral orchitis and epididymitis. Diagnosis of A. seminis infection was confirmed by association of clinical findings, bacterial isolation and 16S rRNA gene sequencing. This result suggests that A. seminis may be an additional cause of infertility in goats, and that sheep may be the source of infection because the mixed farming system allows the contact between sheep and goats in the semiarid region of Northeastern Brazil.

    This retrospective descriptive study was conducted at Queen Sirikit National Institute of Child Health (QSNICH), Bangkok, Thailand to describe the clinical features of gastrointestinal salmonellosis in children. The medical records of 134 patients admitted to QSNICH in 2009 who had a positive stool culture for Salmonella spp were reviewed. Demographic, clinical, laboratory, treatment, culture and antimicrobial sensitivity data were collected and analyzed. The mean age of the patients was 22.9 months (range 0.5 to 158 months); 76.9% were < 2 years old. The male to female ratio was 1.5:1. Salmonella B was most commonly found serogroup (47%). The common clinical manifestations included diarrhea (99.3%), fever (93.3%), dehydration (64.9%) and nausea/vomiting (48.5%). Most of the Salmonella isolates were sensitive to a fluoroquinolone and many were sensitive to Cotrimoxazole, but few were sensitive to ampicillin. There were no significant differences in the clinical manifestations and drug sensitivities of the different Salmonella serogroups, except convulsions were more common in Salmonella E infected patients (p = 0.04) and more Salmonella C isolates were sensitive to ampicillin (p = 0.04). There was no significant correlation between clinical course and antimicrobial treatment, except the duration of diarrhea was significantly longer in patients who received antimicrobial treatment (mean 6.1, SD 4.7 days vs mean 4.2, SD 2.1 days) (p = 0.03). Three patients had Salmonella bacteremia. Three patients died but not directly due to Salmonella infection.

    Schizencephaly is an uncommon structural disorder of cerebral cortical development, characterized by congenital clefts spanning the cerebral hemispheres from the pial surface to the lateral ventricles and lined by cortical gray matter. Either an antenatal environmental incident or a genetic origin could be responsible for this lesion which occurs between the third and fourth month of gestation. We report the clinical and cranial imaging features of 30 children, of whom 15 had unilateral and 15 had bilateral lesions. Their ages at the time of the first presentation ranged from 1 month to 10 years. They were thoroughly studied from clinical, epileptical, imaging and electroencephalographic (EEG) viewpoints. Five patients were investigated by cranial computed tomography (CT), eight by cranial magnetic resonance (MR) imaging, and 17 by both methods. The clinical features consisted of mild hemiparesis in 17 cases (57%), 12/17 were related to a unilateral phenotype (80% of all unilateral forms) and 5/17 to a bilateral phenotype. A tetraparesis was present in nine cases, all of which were due to a bilateral cleft. Bilateral forms were significantly associated with tetraparesis, whereas unilateral forms were associated with hemiparesis. Mental retardation was observed in 17 cases (57%), and was observed significantly more often in bilateral clefts (80%). When both hemispheres are involved, an absence of reorganization of the brain function between the two hemispheres leads to severe mental deficits, in addition to the cerebral anomaly itself. Eleven patients had seizures (seven from unilateral and three from bilateral forms). The degree of malformation was not related to the severity of epilepsy. Migration disorders, such as dysplasia or heterotopia, were observed in 30% of cases and are also important etiopathogenetic factors. The septum pellucidum was absent in 13 cases (43%), with septo-optical dysplasia in two cases. Corpus callosum dysgenesis was noted in 30% of cases

    Full Text Available Eosinophilic esophagitis (EE is a motility disorder of the esophagus that typically presents with dysphagia. The objective of the present study was to explore patient characteristics, clinical and endoscopic features, and response to treatment of patients with EE. Patients were selected retrospectively based on a review of biopsy results from previous endoscopies performed between 2004 and 2008. A total of 54 patients (41 men and 13 women with biopsy-proven EE were included in the study. Further information regarding the patients’ clinical and endoscopic features, and response to treatment were obtained through chart reviews and patient telephone interviews. The mean age of the patients at symptom onset was 30 years. All patients complained of dysphagia, 81% had a history of bolus obstruction, 43% had a history of asthma and 70% had a history of environmental allergies. Thirty-three per cent had a family history of asthma, while 52% had a family history of food or seasonal allergies. The most common endoscopic findings were rings and/or corrugations, which were found in 63% of patients. Swallowed fluticasone therapy resulted in symptom resolution in 74% of patients; however, 79% of these patients relapsed after discontinuing fluticasone therapy and required repeat treatments. Esophageal dilation was complication free and resulted in improvement in 80% of patients. However, 83% of those reporting improvement relapsed within one year. The clinical and endoscopic findings were similar to those found in the literature, with most patients requiring ongoing, repeated therapies. Further studies are needed to assess the safety and efficacy of treatment modalities ideally suited to patients with EE.

    Background Cerebral hemorrhage is common in patients with cancer, but the clinical features and pathogenesis of liver cancer patients with cerebral hemorrhage are not well known. Material/Methods Liver cancer patients who developed cerebral hemorrhage were recruited from the First Affiliated Hospital of Guangxi Medical University between January 2003 and December 2014. We retrospectively analyzed clinical presentations, results of laboratory tests, and imaging examinations. The clinical features and pathogenesis were summarized. Results Among 11133 patients with liver cancer, 9 patients (0.08%), including 3 females and 6 males met the inclusion criteria. The age range was 48–73 years and the average age was 61.67±8.97 years. Five patients did not have traditional hemorrhage risk factors and 4s had the risk factors; however, all had developed hepatocellular carcinoma, and 3 had developed metastasis. All 9 patients showed elevated tumor markers: an increased AFP level was detected in 6 patients, coagulation dysfunctions in 8 patients, and abnormal liver functions in 6 patients. Five patients had developed cerebral hemorrhagic lesions in the lobes of their brains, while hemorrhagic lesions in the basal ganglia occurred in 3 patients and in the brainstem in only 1 patient. Four patients had clear consciousness, while 5 patients were in coma and showed poor prognosis. Conclusions Patients who have liver cancer complicated with cerebral hemorrhage usually lack traditional risk factors of cerebral hemorrhage. The site of cerebral hemorrhage is often detected in the lobes of the brain. Coagulation dysfunctions might be the main pathogenesis of liver cancer complicated with cerebral hemorrhage.

    There is large variation in the molecular genetics and clinical features of hemoglobinopathies in Iran. Studying structural variants of hemoglobin demonstrated that the β-chain variants of hemoglobin S and D-Punjab are more prevalent in the Fars (southwestern Iran) and Kermanshah (western Iran) provinces, respectively. Also, α-chain variants of Hb Q-Iran and Hb Setif are prevalent in western Iran. The molecular basis and clinical severity of thalassemias are extremely heterogenous among Iranians due to the presence of multiethnic groups in the country. β-Thalassemia is more prevalent in northern and southern Iran. Among 52 different β-thalassemia mutations that have been identified among Iranian populations, IVSII-1 G:A is the most frequent mutation in most parts of the country. The presence of IVS I-5 G:C mutation with high frequency in southeastern Iran might reflect gene flow from neighboring countries. A wide spectrum of α-thalassemia alleles has been detected among Iranians with -α(3.7 kb) as the most prevalent α-thalassemia mutation. The prevention program of thalassemia birth in Iran has reduced the birth rate of homozygous β-thalassemia since the implementation of the program in 1997. In this review genetic epidemiology, clinical and hematological aspects of hemoglobinopathies, and the prevention programs of β-thalassemia in Iran will be discussed.

    Full Text Available Abstract Background The coexistence of COPD and asthma is widely recognized but has not been well described. This study characterizes clinical features, spirometry, and chest CT scans of smoking subjects with both COPD and asthma. Methods We performed a cross-sectional study comparing subjects with COPD and asthma to subjects with COPD alone in the COPDGene Study. Results 119 (13% of 915 subjects with COPD reported a history of physician-diagnosed asthma. These subjects were younger (61.3 vs 64.7 years old, p = 0.0001 with lower lifetime smoking intensity (43.7 vs 55.1 pack years, p = 0.0001. More African-Americans reported a history of asthma (33.6% vs 15.6%, p Conclusion Subjects with COPD and asthma represent a relevant clinical population, with worse health-related quality of life. They experience more frequent and severe respiratory exacerbations despite younger age and reduced lifetime smoking history. Trial registration ClinicalTrials.gov: NCT00608764

    Full Text Available Objective To analyze the clinical and cerebrospinal fluid (CSF cytological features of patients with tuberculous meningitis (TBM, to improve early diagnostic accuracy and treatment of TBM. Methods Clinical presentations, etiology and biochemical and cytological features of CSF were analyzed retrospectively among 60 adult cases with TBM hospitalized at Neurology Department of General Hospital of Ningxia Medical University from January 2005 to May 2011. Results Most patients (58/60, 96.67% had fever and headache at onset. In some patients, disturbance of consciousness (9/60, 15.00%, seizure (5/60, 8.33% occurred in 1 week and focal neurological signs developed during the course. Forty?four patients (73.33% had pulmonary tuberculosis history. In CSF examination, acid?fast bacillus positive was found in 8 patients. Positive acid ? fast myobacterium tuberculous culture was detected in 5 patients and positive myobacterium tuberculosis DNA were seen in 5 patients. The main changes of CSF were intracranial hypertension, increase of protein, and decrease of glucose. CSF presented mixed cellular response with predominace in the increasing of leucocytes. During early stage the mean percentage of neutrophil in CSF was less than 40%. After short term (as long as 2 months of regular antituberculotic therapy no significant changes in total cell count and the proportion of neutrophils were seen. In 60 patients, 44 patients were ameliorated, 11 were not healed or were discharged or transferred to other hospital and 5 were dead. Prognosis of patients treated within 3 weeks after onsets was superiorly to those treated at more than 3 weeks after onset. Conclusion There are no specific clinical features in TBM and it is hard to perform early diagnosis for TBM, particularly, existing of low efficiency in pathogenic detection, but pulmonary tuberculosis is of accessary value to diagnose TBM. Whereas mixed cellular response may complementarily provide the diagnosis of

    Background and objective Osteogenesis imperfecta (OI) comprises a group of disorders principally affecting type I collagen which result in increased bone fragility. Children with severe OI suffer recurrent fractures, resulting in severe deformity and growth stunting in many cases, with loss of independent ambulation by the teenage years in over 50% of cases. Recently, cyclical intravenous treatment with pamidronate has proven of benefit to children with severe forms of OI. This article aims to describle clinical features and laboratory manifestations of patient with OI and evaluate outcome of bisphosphonate management. Methods Clinical features, biochemical finding, and management outcome of 104 cases were study. The patients were classified into four major subtypes of Sillience et al. 1979. Patients with severe types were treatment with pamidronate (Aredia) used Rauch protocol 2003. Results Now we have 196 patients (87 females and 109 males) but we studied focus on 104 patients from 98 families (60 males, 44 females) onset at 2.1±3.0 years (median 0.35) with the average fracture bone of 5.9±4.4 times. In there, 17% type I, 8% type II, 63% type III, and 12% type IV. Clinical features include of intrauterine fracture visible on ultrasound 35%, bone deformation after birth 68%, triangle face 76%, long bone deformation 91%, chest deformation 46%, scoliosis 27%, short status 90%, blue sclera 83%, dentinogenesis imperfecta 20%, hearing loss 6%. Thirty patients have been treated with pamidronate at 3.2±3.7 years (4 months to 8 years) during 13±0.8 months (6-30 months). Fourteen patients had fracture bone after 6 months of treatment but no patients had fracture bone after 12 months. Seven patients had been treatment after 1.6±0.5 years, BMD increase from 0.39±0.311 to 0.79±0.105 g/cm2 (P<0.05). One patient had fever reaction after first pamidronate infusion but controlled with standard antipyretic therapy, and do not recur in later treatments. Conclusions OI has

    Using case reports and a review of the literature, the clinical features of envenomation by the genus of Australian funnel web spiders known as Hadronyche, are characterised. Five cases are reported here, including the first life-threatening envenomation by Hadronyche species 14 (the Port Macquarie funnel web). Two severe envenomations by Hadronyche cerberea (the Southern Tree funnel web) and one each by Hadronyche formidabilis (the Northern Tree funnel web) and Hadronyche infensa (the Darling Downs funnel web) are also described. The clinical experience of the authors' provided the five cases described in detail one of which has previously been reported in brief. Eight cases of Hadronyche envenomation from the literature (Medline 1966-1998 and Embase 1980-1998) were analysed in order to draw comparisons between this syndrome and the well described envenomation syndrome of Atrax robustus (the Sydney funnel web). Reports of funnel web spider antivenom use to Commonwealth Serum Laboratories (CSL) between 1995 and June 1998 were also examined. The biology of these dangerous spiders, their geographic distribution, venom characteristics and management issues are addressed. It is concluded that bites from at least six Hadronyche species have produced a life-threatening envenomation syndrome clinically indistinguishable from that of Atrax robustus. Atrax robustus derived antivenom is effective although antivenom requirements may be greater than for Atrax envenomation. Antivenom supplies are limited and sufficient stocks to treat a severe envenomation are unlikely to be found in any one institution. Pressure-immobilisation first aid is effective in delaying onset of envenomation, may enhance local inactivation of venom and early removal can result in rapid clinical deterioration.

    Because of the difficulties of ascertaining episode of hypomania by past history of the patients, it is of clinical value to find variables which predict the development of bipolar II disorder in depressive patients. Taking advantage of relatively long hospitalization, the authors tried to elucidate fine clinical features of the soft bipolarity. The subjects were 39 patients with Major Depressive Episode, diagnosed according to the 4th edition of the Diagnostic and Statistical Manual criteria. Among them, 15 patients were diagnosed as bipolar II disorder (BPII), whereas 24 patients were with unipolar depression (UP), using a structured clinical interview to assess the mood spectrum (SCI-MOODS). In addition to ordinary clinical and demographic variables, the authors studied fine symptomatology of depression, premorbid personality, and interpersonal relationship. Continuous variables were analyzed by t-test. Categorical variables were tested by chi2 analysis. In terms of premorbid personality, manic type (Zerssen) was found more frequently in BPII (UP 2/24, BPII 9/15, P < 0.05). Patients with BPII tended to show apparently quick disappearance of depressive symptoms (UP 2/24, BPII 9/15, P = 0.01). The most prominent result was a high prevalence of comorbidity of borderline personality disorder (BPD) among BPII (UP 0/24, BPII 6/15, P = 0.02). As Akiskal indicated that mood lability represents the most powerful predictor of hypomanias, patients with BPII showed quick response in mood to admission. The current subjects with BPII had high frequency of manic type of premorbid personality, indicating the usefulness of this variable for the prediction of hypomanias. Finally, the authors could observe development of BPD during hospitalization exclusively among BPII, to support the possibility of BPD as a state effect of BPII.

    Full Text Available BACKGROUND: The new epidemiological scenario of orally transmitted Chagas disease that has emerged in Brazil, and mainly in the Amazon region, needs to be addressed with a new and systematic focus. Belém, the capital of Pará state, reports the highest number of acute Chagas disease (ACD cases associated with the consumption of açaí juice. METHODOLOGY/PRINCIPAL FINDINGS: The wild and domestic enzootic transmission cycles of Trypanosoma cruzi were evaluated in the two locations (Jurunas and Val-de Cães that report the majority of the autochthonous cases of ACD in Belém city. Moreover, we evaluated the enzootic cycle on the three islands that provide most of the açaí fruit that is consumed in these localities. We employed parasitological and serological tests throughout to evaluate infectivity competence and exposure to T. cruzi. In Val-de-Cães, no wild mammal presented positive parasitological tests, and 56% seroprevalence was observed, with low serological titers. Three of 14 triatomines were found to be infected (TcI. This unexpected epidemiological picture does not explain the high number of autochthonous ACD cases. In Jurunas, the cases of ACD could not be autochthonous because of the absence of any enzootic cycle of T. cruzi. In contrast, in the 3 island areas from which the açaí fruit originates, 66.7% of wild mammals and two dogs displayed positive hemocultures, and 15.6% of triatomines were found to be infected by T. cruzi. Genotyping by mini-exon gene and PCR-RFLP (1f8/Akw21I targeting revealed that the mammals and triatomines from the islands harbored TcI and Trypanosoma rangeli in single and mixed infections. CONCLUSION/SIGNIFICANCE: These findings show that cases of Chagas disease in the urban area of Belém may be derived from infected triatomines coming together with the açaí fruits from distant islands. We term this new epidemiological feature of Chagas disease as "Distantiae transmission".

    Full Text Available Abstract Aorto-atrial fistulas (AAF are rare but important pathophysiologic conditions of the aorta and have varied presentations such as acute pulmonary edema, chronic heart failure and incidental detection of the fistula. A variety of mechanisms such as aortic dissection, endocarditis with pseudoaneurysm formation, post surgical scenarios or trauma may precipitate the fistula formation. With increasing survival of patients, particularly following complex aortic reconstructive surgeries and redo valve surgeries, recognition of this complication, its clinical features and echocardiographic diagnosis is important. Since physical exam in this condition may be misleading, echocardiography serves as the cornerstone for diagnosis. The case below illustrates aorto-left atrial fistula formation following redo aortic valve surgery with slowly progressive symptoms of heart failure. A brief review of the existing literature of this entity is presented including emphasis on echocardiographic diagnosis and treatment.

    To describe the US findings of corpus luteum cyst rupture in order to elucidate the associated clinical features. Twenty patients with proven corpus luteum cyst rupture were included in this study. The US findings of these patients were retrospectively analyzed in terms of the presence of designable cyst, size of the cyst, thickness and blood flow of the cyst wall, extension and echogenicity of peritoneal fluid, and involved site (right or left ovary). We also surveyed the clinical features such as the onset period according to the menstrual cycle, and the presence of suspectable cause. Fourteen of the 20 patients revealed designable cysts (mean diameter of 2.6 cm) with thick walled cysts (mean thickness, 4.6 mm, 2.4-6.8 mm) and increased blood flow. Six patients didn't reveal any cyst but only hematoma in adnexa. All patients had hemoperitoneum in the pelvic cavity, and the hemoperitoneum was extended to Morrison's pouch in 8 patients and to the subphrenic space in 6. The cysts occurred in the right adnexa in 15 patients and in the left in 5. Mean interval from the last menstrual period (LMP) was 26 days (13-44 days) and 6 of the 8 patients for whom it had been possible to obtain detailed history taking had had coitus just before the occurrence of symptom. When women who are hospitalized for acute abdomen and who are in luteal phase reveal US findings of hematoma or thick-walled cyst in adnexa and hemoperitoneum, a corpus luteum cyst rupture is highly suspected. In our case study the corpus luteum cyst rupture predominantly occurred in the right side, and the most suspectable cause was trauma such as coitus in the luteal phase

    Introduction Laryngeal tuberculosis (LTB) is the most frequent granulomatous disease of the larynx and represents less than 2% of extrapulmonary TB cases. There are no pathognomonic clinical and endoscopic features of this disease and studies on LTB that can assist in its diagnostic characterization are lacking. Objective To identify factors associated with clinical and topographical features of LTB. Method a retrospective cross-sectional study was conducted from the medical records of 36 patients with confirmed LTB diagnosis. Results Dysphonia and cough were the main symptoms presented by patients and the true vocal folds the most frequently affected site. The average of the duration of the disease evolution was significantly higher in patients with dysphonia than in patients without this symptom. We observed association between dysphonia and true vocal fold lesions and between odynophagia and lesions in the epiglottis, arytenoids and aryepiglottic folds. Odynophagia was more frequent in individuals with lesions in four or more laryngeal sites. Weight loss equal or above 10% of the body weight was more frequent in patients with odynophagia as first symptom and in patients with ulcerated lesion. Dyspnea on exertion was more frequent in individuals with more extensive laryngeal lesions. The percentage of smokers with lesions in four or more laryngeal sites was greater than that found in non-smokers. Laryngeal tissue fragment bacilloscopy and culture examinations were less positive than sputum ones. Conclusions Smoking appears to be associated with the development of more extensive LTB lesions, and LTB with dyspnea on exertion and odynophagia with consequent impairment of nutritional status. We emphasize the need for histopathologic confirmation, once positive sputum bacteriological examinations seem not to necessarily reflect laryngeal involvement. PMID:27077734

    Objective To investigate clinical features of pheochromocytoma and summarize experiences of anesthetic management during the perioperative period. Methods Two hundred and fifty eight patients who were diagnosed with pheochromocytoma in our hospital were reviewed retrospectively for clinical features. According to different preoperative pharmalogical preparations, perioperative mortalities were analyzed in three periods (Period 1: January 1955-December 1975; Period 2: January 1976-December 1994; Period 3: January 1995-July 2001). In Period 3, hemodynamic changes in the patients undergoing different anesthetic methods were analyzed. Results About 5.8% (15/258) of pheochromocytoma was an integral part of multiple endocrine neoplasia (MEN) type Ⅱ or mixed type. Sixty percent (149/249) of the patients who had undergone surgery possessed evidence of catecholamine cardiac toxicity preoperatively. Impaired glucose tolerance was found in 59% (147/249) of the patients before surgery. Perioperative mortality was significantly decreased from 8% (5/60) in Period 1 to 1.2% (1/75) in Period 2 (P<0.01). No perioperative deaths occurred in Period 3. The volume infused during the operation was significantly higher both in the epidural anesthesia group (3474 ml±624 ml, P<0.01) and in the epidural plus general anesthesia group (3654 ml±475 ml, P<0.01) than in the general anesthesia group (2534 ml±512 ml). There were favorable hemodynamic characteristics in patients before removal of the tumor in the epidural anesthesia group and in the epidural plus general anesthesia group, as compared with the general anesthesia group. Conclusions A positive surgical outcome of the excision of pheochromocytoma depends on multiple factors, including careful assessment of potential vital organ damage before surgery and restoration of blood volume by establishing α-blockade preoperatively, meticulous anesthetic management of patients during surgery, and appropriate circulatory support after

    1984-09-01

    A study of the neuromuscular features of acromegaly was performed in six patients. Clinical assessment was supplemented by quadriceps force measurements, plasma creatine kinase (CK) activities, electromyography (EMG) and nerve conduction studies. Muscle mass was measured by urinary creatinine/height indices (CHI) and cross sectional area (CSA) of thighs and calves on computed tomography. Quadriceps force/unit cross sectional area was derived. Needle biopsies of vastus lateralis were studied by histochemical and ultrastructural methods. Mean fibre area (MFA) and fibre type proportions were measured. Most of the subjects studied had muscle pain and proximal muscle weakness confirmed by quadriceps force measurements. This occurred in the absence of muscle wasting, as shown by cross sectional area measurements and normal or raised creatinine/height indices. "Myopathic" features were demonstrated by needle biopsy in half the patients and occasionally by electromyography and raised plasma creatine kinase activity. Abnormalities on needle biopsy included variation in fibre size, type 2 fibre atrophy and large type 1 MFA relative to type 2 MFA. Electronmicroscopy showed the non-specific findings of increased glycogen accumulation, excess lipofuscin pigment and myofilament loss.

    The authors discuss the diagnostic criteria for pedophilia and review the literature on its clinical features, including data on prevalence, gender, age of onset, number of victims, frequency and type of acts, violence, impulsivity, and insight. Findings concerning the characteristics of victims (e.g., sex, age, relationship to the pedophile) and research on pedophilic subtypes-exclusive versus nonexclusive; incestuous versus nonincestuous; heterosexual, homosexual, or bisexual-are reviewed. Studies have shown that pedophiles may share many psychiatric features beyond deviant sexual desire, including high rates of comorbid axis I disorders (affective disorders, substance use disorders, impulse control disorders, other paraphilias) as well as severe axis II psychopathology (especially antisocial and Cluster C personality disorders). The authors present several possible etiological models for pedophilia and conclude that further research is needed concerning the etiological role of a childhood history of sexual abuse as well as the underlying neurobiology of deviant sexual arousal and decreased erotic differentiation. Finally, findings concerning pharmacological and cognitive-behavioral treatments for pedophilia are briefly reviewed. Recidivism, drop-out, and noncompliance are significant problems in the treatment of pedophilia. The authors review predictors of treatment outcome and conclude that pedophilia is extremely difficult to treat and that effective treatment needs to be intensive, long-term, and comprehensive, possibly with lifetime follow-up.

    Full Text Available Macrophagic myofasciitis (MMF is an emerging condition characterized by specific muscle lesions assessing abnormal long-term persistence of aluminium hydroxide within macrophages at the site of previous immunization. Affected patients usually are middle-aged adults, mainly presenting with diffuse arthromyalgias, chronic fatigue, and marked cognitive deficits, not related to pain, fatigue or depression. Clinical features usually correspond to that observed in chronic fatigue syndrome/myalgic encephalomyelitis. Representative features of MMF-associated cognitive dysfunction include dysexecutive syndrome, visual memory impairment and left ear extinction at dichotic listening test. Most patients fulfil criteria for non-amnestic/dysexecutive mild cognitive impairment, even if some cognitive deficits appear unusually severe. Cognitive dysfunction seems stable over time despite marked fluctuations. Evoked potentials may show abnormalities in keeping with central nervous system involvement, with a neurophysiological pattern suggestive of demyelination. Brain perfusion SPECT shows a pattern of diffuse cortical and subcortical abnormalities, with hypoperfusions correlating with cognitive deficiencies. The combination of musculoskeletal pain, chronic fatigue and cognitive disturbance generates chronic disability with possible social exclusion. Classical therapeutic approaches are usually unsatisfactory making patient care difficult.

    Full Text Available Following a large outbreak of community-acquired psittacosis in 2002 in residents of the Blue Mountains, New South Wales, Australia, we reviewed new cases in this area over a 7-year period from 2003 to 2009. Using the 2010 criteria from the Centers for Disease Control National Notifiable Diseases Surveillance System, 85 patients with possible psittacosis were identified, of which 48 were identified as definite or probable infection. Clinical features of these cases are summarized. In addition to Chlamydia-specific serology, specimens, where available, underwent nucleic acid testing for chlamydial DNA using real-time PCR. Chlamydophila psittaci DNA was detected in samples from 23 patients. Four of 18 specimens were culture positive. This is the first description of endemic psittacosis, and is characterized in this location by community-acquired psittacosis resulting from inadvertent exposure to birds. The disease is likely to be under-diagnosed, and may often be mistaken for gastroenteritis or meningitis given the frequency of non-respiratory symptoms, particularly without a history of contact with birds. Clinical characteristics of endemic and outbreak-associated cases were similar. The nature of exposure, risk factors and reasons for the occurrence of outbreaks of psittacosis require further investigation.

    Full Text Available Objective: The aim of this study was to determine the prevalence of macroprolactin in patients with hyperprolactinemia in our region, and to determine the clinical and neuroradiological features of the affected individuals. Materials and Methods: We used the Roche Elecsys Prolactin assay (Prolactin II with polyethylene glycol precipitation to identify macroprolactin; recovery of ≤40% was considered to represent significant macroprolactinemia. Of 156 consecutive patients with hyperprolactinemia, macroprolactin was found in ten (6.4%. Clinical records of these patients were reviewed. Results: Of ten patients with macroprolactinemia, two males presented with infertility and two with decreased libido and erectile dysfunction. Females presented with menstrual dysfunction, with or without infertility. Pituitary adenomas were identified in two of seven patients who underwent neuroimaging. Dopamine agonists were prescribed to seven patients; their symptoms were not affected by this therapy. Conclusions: Macroprolactin is a cause of misdiagnosis and inappropriate treatment in patients with hyperprolactinemia. It is important to be aware of the extent to which the assay system used in the measurement of prolactin may detect macroprolactin, and to have a available validated method to confirm its presence. This will ensure appropriate management for patients with this benign condition. Turk Jem 2008; 12: 46-9

    The aim of this study was to investigate the clinical features and treatment results of endophthalmitis after cataract surgery. Five patients with endophthalmitis after phacoemulsification with intraocular lens implantation were enrolled in this study. The pathogenesis, clinical manifestation, and surgical outcomes of 5 patients were compared. Three patients were surgically treated with anterior chamber irrigation and vitrectomy with intravitreal injection. The remaining two patients were medically treated with an intravitreal injection of vancomycin and ceftazidime. Treatment results of the five patients were analyzed. Four patients had positive cultures for bacteria (two cases Staphylococcus epidermidis, one case Enterococcus faecalis, and one case head-like Staphylococcus). The culture of the fifth patient did not have bacterial growth. One year following treatment, four patients had restored visual acuity and a clear vitreous cavity. Retinal detachment and other complications were not observed. The remaining patient had a visual acuity of index at 30 cm one year following treatment. For patients with endophthalmitis after cataract surgery, a biochemical laboratory examination should be promptly performed and should include a bacterial culture and drug sensitivity test. When necessary, vitrectomy combined with an intravitreal injection of vancomycin should be performed to treat the infection early and to help retain useful vision.

    Full Text Available Background: There have been few reports on primary cicatricial alopecias (PCR especially from Asia (PCA. Aims: To study the clinical, pathological and dermoscopic characteristics of PCA among Chinese patients. Methods: A retrospective analysis of the clinical data of 59 patients with PCA was conducted and the dermoscopic, pathological, treatment and prognosis characteristics analyzed. Fisher′s Chi-square exact test, Kruskal-Wallis and Spearman rank correlation test were performed. Results: The ratio of neutrophilic to lymphocytic cicatricial alopecias was about 1.3:1 in this group. The most frequent disorder was folliculitis decalvans. Follicular openings were absent on dermoscopy in all cases except alopecia mucinosa. Patulous follicular openings were characterisitc of alopecia mucinosa. After treatment, an increase in short vellus hairs was the earliest feature, while telangiectasia, epidermal scale, follicular hyperkeratosis, pustules and hair diameter diversity gradually decreased or even disappeared. Improvement in the areas of hair loss after treatment was seen more often in discoid lupus erythematosus, folliculitis decalvans and dissecting cellulitis than in patients with classic pseudopelade of Brocq. Nine patients (13.6% relapsed after cessation of therapy. Female patients needed longer treatment times. Long duration, large areas of hair loss and shorter treatment courses were the major factors in relapses. Conclusions: Dermatoscopy provides a rapid, practical and useful aid for the diagnosis of PCA and also to assess disease activity. Patulous follicular openings are a specific dermoscopic sign of alopecia mucinosa. Lichen planopilaris is less common in China than in the West.

    Background In 2008 a nosocomial outbreak of five cases of viral hemorrhagic fever due to a novel arenavirus, Lujo virus, occurred in Johannesburg, South Africa. Lujo virus is only the second pathogenic arenavirus, after Lassa virus, to be recognized in Africa and the first in over 40 years. Because of the remote, resource-poor, and often politically unstable regions where Lassa fever and other viral hemorrhagic fevers typically occur, there have been few opportunities to undertake in-depth study of their clinical manifestations, transmission dynamics, pathogenesis, or response to treatment options typically available in industrialized countries. Methods and Findings We describe the clinical features of five cases of Lujo hemorrhagic fever and summarize their clinical management, as well as providing additional epidemiologic detail regarding the 2008 outbreak. Illness typically began with the abrupt onset of fever, malaise, headache, and myalgias followed successively by sore throat, chest pain, gastrointestinal symptoms, rash, minor hemorrhage, subconjunctival injection, and neck and facial swelling over the first week of illness. No major hemorrhage was noted. Neurological signs were sometimes seen in the late stages. Shock and multi-organ system failure, often with evidence of disseminated intravascular coagulopathy, ensued in the second week, with death in four of the five cases. Distinctive treatment components of the one surviving patient included rapid commencement of the antiviral drug ribavirin and administration of HMG-CoA reductase inhibitors (statins), N-acetylcysteine, and recombinant factor VIIa. Conclusions Lujo virus causes a clinical syndrome remarkably similar to Lassa fever. Considering the high case-fatality and significant logistical impediments to controlled treatment efficacy trials for viral hemorrhagic fever, it is both logical and ethical to explore the use of the various compounds used in the treatment of the surviving case reported here

    AIM: To summarize clinical features of probable severe acute respiratory syndrome (SARS) in Beijing.METHODS: Retrospective cases involving 801 patients admitted to hospitals in Beijing between March and June 2003, with a diagnosis of probable SARS, moderate type.The series of clinical manifestation, laboratory and radiograph data obtained from 801 cases were analyzed. RESULTS: One to three days after the onset of SARS, the major clinical symptoms were fever (in 88.14% of patients), fatigue, headache, myalgia, arthralgia (25-36%), etc. The counts of WBC (in 22.56% of patients) lymphocyte (70.25%)and CD3, CD4, CD8 positive T cells (70%) decreased. From 4-7 d, the unspecific symptoms became weak; however, the rates of low respiratory tract symptoms, such as cough (24.18%), sputum production (14.26%), chest distress (21.04%) and shortness of breath (9.23%) increased, so did the abnormal rates on chest radiograph or CT. The low counts of WBC, lymphocyte and CD3, CD4, CD8 positiveT cells touched bottom. From 8 to 16 d, the patients presented progressive cough (29.96%), sputum production (13.09%), chest distress (29.96%) and shortness of breath (35.34%). All patients had infiltrates on chest radiograph or CT, some even with multi-infiltrates. Two weeks later, patients' respiratory symptoms started to alleviate, the infiltrates on the lung began to absorb gradually, the counts of WBC, lymphocyte and CD3, CD4, CD8 positive T cells were restored to normality.CONCLUSION: The data reported here provide evidence that the course of SARS could be divided into four stages, namely the initial stage, progressive stage, fastigium and convalescent stage.

    Full Text Available The World Health Organization has declared tuberculosis (TB to be a global emergency, as it remains the most common single cause of morbidity and mortality worldwide. TB is caused by the acid-fast bacillus Mycobacterium tuberculosis and primarily affects the lungs [pulmonary TB (PTB]. It can also affect any other part of the body [extrapulmonary TB (EPTB]. It is estimated that 1.4% of patients with PTB will eventually develop ocular disease; however, in the majority of cases of ocular TB, PTB may not be documented. Ocular TB infection is usually a result of hematogenous spread during PTB or EPTB. Symptomatic disease most commonly develops after reactivation of dormant foci in the ocular tissue rather than being the manifestation of the initial infection. Immune-mediated ocular TB can occur due to hypersensitivity to M. tuberculosis antigens from a distant focus (such as lungs, despite the absence of the bacterium in the eye. The most common clinical presentation of intraocular inflammation (uveitis due to TB appears to be posterior uveitis, followed by anterior uveitis, panuveitis and intermediate uveitis. The absence of uniform diagnostic criteria for intraocular TB has led to confusion regarding its diagnosis and management. Recent studies on the clinical importance of purified protein derivative (PPD skin test, interferon-gamma release assays, chest computed tomography and polymerase chain reaction have provided a new approach to diagnosing ocular TB. This review series focuses on the clinical features, diagnostic techniques, diagnostic criteria, and treatment modalities in the light of recent literature. (Turk J Ophthalmol 2011; 41: 171-81

    Full Text Available Summary Objective: To evaluate the sponsored centers for clinical trial in the respiratory care setting in Brazil: profile; logistics and structure. Methods: Principal investigators (29 and subinvestigators (30 of 39 research centers completed the questionnaires that addressed personal identification and training of researchers, the centers' facilities and advantages and/or disadvantages of performing sponsored trials. Results: 75.6% of the centers were located in southern and southeastern Brazil. Most principal investigators were men with a mean age of 53.4 years. The clinical trials in the respiratory care setting focus on asthma and chronic obstructive pulmonar disease (COPD. 80% of the researchers cited delay of the Conep and Anvisa as a barrier to performing research. The advantages of participating in clinical trials were updating knowledge of the researcher and the team, and additional income for the team. The main disadvantages mentioned by the researchers included low financial compensation for the performed workload, and time availability. The median number of professionals per research center was six people, predominantly physicians. Conclusion: The number of research centers in the respiratory care setting in Brazil is still relatively small. The teams have good training for performing the clinical trials. Asthma and COPD are the most studied diseases in sponsored clinical trials. The main barrier is delay by the Conep and Anvisa. The factors that lead investigators to participate range from being updated along with the team, to site and staff financial issues; the main disadvantage is the low compensation for the required workload demand.

    as well as to investigate the role of viral pathogens in the etiology of GCS cases from Belem (PA, Brazil. PATIENTS AND METHODS: From August 1996 to December 2002, ten children with a clinical diagnosis of GCS were investigated through routine laboratory exams and serologically screened for several virus specific antibodies. A diagnosis of GCS was considered for cases that presented clinical aspects considered suggestive, together with one or more of the following criteria: elevated titers of hepatic enzymes, lymphocytosis, positive viral serology or history of a prior vaccination. RESULTS: Six out of 10 children (60% showed evidence of HHV6 primary infection, as demonstrated through specific IgM-antibody positivity. CONCLUSION: Anti-HHV6-IgM antibody positivity in 6/10 patients suggests that the pathogen can play a role in the etiology of GCS. Consequently, the authors recommend that this virus is added to the routine serological tests when exanthematous processes are concerned, especially those with a morphology suggestive of GCS.

    Background Pathological fractures signify a potentially more aggressive subset of the original disease with higher misdiagnosis rates and inferior oncologic results.The purpose of the present study was to explore the clinical features of neoplastic pathological fracture in extremities.Methods From August 2002 to December 2010,a consecutive series of 139 patients suffering neoplastic pathological fracture were recruited,including 79 males and 60 females with a mean age of 31.3 years.Fractures were classified into five groups:tumor-like lesions (55),benign bone tumors (13),giant cell tumors (7),primary malignant bone tumors (28),and metastatic bone tumors (36).Based on their inducing forces,pathologic fractures were classified into four grades:spontaneous fracture,functional fracture,minor injury,and traumatic injury.Patients' age,fracture site,histological diagnoses,fracture forces,prodromes,and misdiagnosis were well reviewed.Kruskal-Wallis and x2 tests were used to compare forces and prodromes within different types of bone tumors.Results The highest pathologic fracture morbidity was 32.3% (45/139),which lay in the 11-20 year group,and 86.1%of metastatic tumors occurred in the 50-80 year group.The common sites of fractures were femur,humerus,and tibia.The fracture forces in benign bone tumors and tumor-like lesions are the strongest,followed by metastatic tumors and primary malignant bone tumors (Hc=80.980,P=0.000).Sixty-seven patients (48.2%) had local prodromes before pathologic fracture.The incidence rates of prodromes between primary malignant tumors and metastatic bone tumors had no significant difference (P=0.146),but they were all obviously higher than that of benign bone tumors and tumor-like lesions.Twenty patients experienced misdiagnosis.Conclusion Minor injury forces and local prodromes are clinical features of neoplastic pathologic fractures and they are also the critical factor avoiding misdiagnoses.

    Cluster headache (CH) is a rare underdiagnosed primary headache disorder with very severe unilateral pain and autonomic symptoms. Clinical characteristics of Korean patients with CH have not yet been reported. We analyzed the clinical features of CH patients from 11 university hospitals in Korea. Among a total of 200 patients with CH, only 1 patient had chronic CH. The average age of CH patients was 38.1 ± 8.9 years (range 19–60 years) and the average age of onset was 30.7 ± 10.3 years (range 10–57 years). The male-to-female ratio was 7:1 (2.9:1 among teen-onset and 11.7:1 among twenties-onset). Pain was very severe at 9.3 ± 1.0 on the visual analogue scale. The average duration of each attack was 100.6 ± 55.6 minutes and a bout of CH lasted 6.5 ± 4.5 weeks. Autonomic symptoms were present in 93.5% and restlessness or agitation was present in 43.5% of patients. Patients suffered 3.0 ± 3.5 (range 1–25) bouts over 7.3 ± 6.7 (range 1–30) years. Diurnal periodicity and season propensity were present in 68.5% and 44.0% of patients, respectively. There were no sex differences in associated symptoms or diurnal and seasonal periodicity. Korean CH patients had a high male-to-female ratio, relatively short bout duration, and low proportion of chronic CH, unlike CH patients in Western countries. PMID:28145655

    Objective To investigate the incidence, imaging and clinical characteristics in elderly patients with coronary artery ectasia (CAE). Methods A retrospective analysis was conducted on patients with CAE who underwent coronary angiography between January 2006 and December 2012. According to age, the enrolled patients were divided into two groups (elderly group, age≥ 65 years; non-elderly group, age < 65 years). The clinical feature, imaging characteristics and the 5-year survival rate of the two groups were compared.Results The preva-lence of CAE in elderly patients was 0.33%. Patients in elderly group were found to have significantly higher proportion of female (30.1%vs. 10.1%,P< 0.001), three-vessel disease (60.5%vs. 45.2%,P = 0.003) and localized ectasia (55.0%vs. 40.2%,P = 0.003). In addition, body mass index (20.90 ± 2.71 kg/m2vs. 22.31 ± 2.98 kg/m2,P < 0.001) and percentage of current smokers (45.0%vs. 64.6%,P < 0.001) were significantly lower in elderly group. Cumulative survival curves demonstrated reduced 5-year cumulative survival at the follow-up in the elderly group compared with the non-elderly group (88.0%vs. 96.0%,P = 0.002). But the 5-year event free survival rate failed to show a significant difference between the two groups (31.0%vs. 35.0%,P= 0.311).ConclusionThe prevalence of CAE in elderly patients was 0.33%, which was about 1/3 of the entire numbers of CAE patients. There were significant differences between the elderly and the non-elderly patients with CAE in terms of coronary artery disease risk factors and coronary artery ectatic characteristics. CAE might be asso-ciated with increased mortality risk in the elderly.

    Background An increasing incidence of Crohn' s disease has been found in China in recent years.Our study has been focused on evaluating the diversity of the clinical manifestations of Crohn' s disease in order to improve early diagnostic accuracy and therapeutic efficacy.Methods Thirty patients with active Crohn's disease were enrolled and their clinical data, including diagnostic and therapeutic results, were analyzed. Endoscopy combined with histological examination of biopsy specimens provided characteristic features of the disease. Transabdominal bowel sonography (TABS) was used for detecting intestinal complications. Nutritional supportive therapy was given to 20 subjects with active cases of the disease.Results Most patients were young adults with a higher proportion of females to males (ratio: 1.14:1). The disease affects any segment or a combination of segments along with the alimentary tract(from the mouth to the anus). In this study, the colon and small bowel were the major sites involved.Recurrent episodes of abdominal pain in the right lower quadrant and watery diarrhea were the most common symptoms. Granulomas were identifiable in nearly one-third (30.8%) of all biopsy specimens. In moderate cases of the disease, remission was achieved more quickly through the use of oral prednisone therapy than with SASP or 5-ASA. Beneficial effects on the host' s nutritional status were observed. Immunosuppressives were used on an individual basis and showed variable therapeutic effects. Sixteen patients had surgery due to intestinal obstruction or failure to respond to drug therapies. Rapid improvement after surgery was reported. Conclusion Endoscopy (with biopsy) and TABS were both crucial procedures for diagnosis. SASP(or 5-ASA) and prednisone were effective as inductive therapies. Azathioprine has demonstrable benefits after induction therapy with prednisone. Surgery, as an alternative treatment, provided another effective choice in selected patients.

Material and Method: The records of 35 patients with orbital neurogenic tumors who were diagnosed and treated at Ankara University Faculty of Medicine, Department of Ophthalmology, between 1998 and 2011 were evaluated retrospectively. Results: Orbitotomy via a cutaneous approach was performed in 21 (60% cases and orbitotomy via a transconjunctival approach was performed in 7 (20% cases. Three (8% cases had been operated at different centers. Four (12% cases were diagnosed clinically. Total excisional biopsy was performed in 11 (31.4% cases, subtotal excisional biopsy was performed in 7 (20%, and incisional biopsy was performed in 10 (28.6% cases. 14 (40% 35 cases were diagnosed as meningioma, 12 (34% as peripheral nerve sheath tumor, and 9 (26% cases were diagnosed as optic nerve glioma. Six (43% meningioma cases were optic nerve sheath meningioma, 5 (36% were sphenoid wing meningioma, 2 (14% were ectopic meningioma, and 1 (7% was perisellar meningioma. Six (50% of peripheral nerve sheath tumors were schwannoma, 2 (16% were solitary neurofibroma, 4 (34% were plexiform neurofibroma. External beam radiotherapy was performed in 15 (42.8% cases, cyberknife radiosurgery in 1 (2.8% , chemotherapy in 1 (2.8%, and enucleation ( because of neovascular glaucoma and vitreous hemorrhage was performed in 1 (2.8% case. Discussion: The most common orbital neurogenic tumors are meningioma, peripheral nerve sheath tumor, and optic nerve glioma. For meningioma and glioma, external beam radiotherapy is required; for schwannoma and solitary neurofibroma, total excisional biopsy is the preferred treatment. The success of visual and anatomic results are high after treatment. (Turk J Ophthalmol 2013; 43: 335-9

    The present report aimed to perform a molecular epidemiological survey by investigating the presence of virulence factors in E. faecalis isolated from different human clinical (n = 57) and food samples (n = 55) in Porto Alegre, Brazil, collected from 2006 to 2009. In addition, the ability to form biofilm in vitro on polystyrene and the β-haemolytic and gelatinase activities were determined. Clinical strains presented a higher prevalence of aggregation substance (agg), enterococcal surface protein (esp) and cytolysin (cylA) genes when compared with food isolates. The esp gene was found only in clinical strains. On the other hand, the gelatinase (gelE) and adherence factor (ace) genes had similar prevalence among the strains, showing the widespread occurrence of these virulence factors among food and clinical E. faecalis strains in South Brazil. More than three virulence factor genes were detected in 77.2% and 18.2% of clinical and food strains, respectively. Gelatinase and β-haemolysin activities were not associated with the presence of gelE and cylA genes. The ability to produce biofilm was detected in 100% of clinical and 94.6% of food isolates, and clinical strains were more able to form biofilm than the food isolates (Student's t-test, p detected in clinical strains.

    Glutaric aciduria type 1 is a rare neurometabolic disease with high morbidity. To describe the MR imaging abnormalities in glutaric aciduria type 1 and to identify any association between the clinical and imaging features. MRI scans of 29 children (mean age: 16.9 months) with confirmed diagnosis of glutaric aciduria type 1 were retrospectively reviewed. Gray matter and white matter scores were calculated based on a previously published pattern-recognition approach of assessing leukoencephalopathies. Hippocampal formation and opercular topography were assessed in relation to the known embryological basis. MRI scores were correlated with morbidity score. The most consistent MRI abnormality was widened operculum with dilatation of the subarachnoid spaces surrounding underdeveloped frontotemporal lobes. Incomplete hippocampal inversion was also seen. The globus pallidus was the most frequently involved gray matter structure (86%). In addition to the central tegmental tract, white matter abnormalities preferentially involved the central and periventricular regions. The morbidity score correlated with the gray matter abnormality score (P = 0.004). Patients with dystonia had higher gray matter and morbidity scores. Morbidity is significantly correlated with abnormality of gray matter, rather than white matter, whether secondary to acute encephalopathic crisis or insidious onset disease. (orig.)

    Context It has been reported that childhood psychotic symptoms are common in the general population and may signal neurodevelopmental processes that lead to schizophrenia. However, it is not clear whether these symptoms are associated with the same extensive risk factors established for adult schizophrenia. Objective To examine the construct validity of children’s self-reported psychotic symptoms by testing whether these symptoms share the risk factors and clinical features of adult schizophrenia. Design Prospective, longitudinal cohort study of a nationally representative birth cohort in Great Britain. Participants A total of 2232 twelve-year-old children followed up since age 5 years (retention, 96%). Main Outcome Measure Children’s self-reported hallucinations and delusions. Results Children’s psychotic symptoms are familial and heritable and are associated with social risk factors (eg, urbanicity); cognitive impairments at age 5; home-rearing risk factors (eg, maternal expressed emotion); behavioral, emotional, and educational problems at age 5; and comorbid conditions, including self-harm. Conclusions The results provide a comprehensive picture of the construct validity of children’s self-reported psychotic symptoms. For researchers, the findings indicate that children who have psychotic symptoms can be recruited for neuroscience research to determine the pathogenesis of schizophrenia. For clinicians, the findings indicate that psychotic symptoms in childhood are often a marker of an impaired developmental process and should be actively assessed. PMID:20368509

    Mucocele is a benign lesion occurring in the buccal mucosa as a result of the rupture of a salivary gland duct and consequent outpouring of mucin into soft tissue. It is usually caused by a local trauma, although in many cases the etiology is uncertain. Mucocele is more commonly found in children and young adults, and the most frequent site is the lower inner portion of the lips. Fibroma, on the other hand, is a benign tumor of fibrous connective tissue that can be considered a reactionary connective tissue hyperplasia in response to trauma and irritation. They usually present hard consistency, are nodular and asymptomatic, with a similar color to the mucosa, sessile base, smooth surface, located in the buccal mucosa along the line of occlusion, tongue and lip mucosa. Conventional treatment for both lesions is conservative surgical excision. Recurrence rate is low for fibroma and high for oral mucoceles. This report presents a series of cases of mucocele and fibroma treated by surgical excision or enucleation and the respective follow-up routine in the dental clinic and discusses the features to be considered in order to distinguish these lesions from each other.

    Full Text Available Abstract Background Although several studies have been performed on risk factors and natural course of NASH, it seems that NASH tends to be more than a disease confined to strict boundaries. The objective of this study was to assess the clinical and paraclinical features and risk factors for non-alcoholic steatohepatitis (NASH patients in an Iranian population Methods Patients with histologically confirmed NASH who had elevated liver aminotransaminases, negative serologic markers of viral or autoimmune hepatitis and no findings in favor of metabolic liver disease were enrolled. A careful history was taken regarding alcohol intake. Results 53 patients consisting of 32 male and 21 female entered the study. The mean age was 37.8 ± 11.3 years. Twenty-six patients (55.3% were overweight, 15 (31.9% obese, 40 (75.5% dyslipidemic, and three patients (5.7% were diabetic. Liver biopsy showed mild steatosis in 35.7%, moderate steatosis in 53.6%, and severe forms in 10.7%. In 80.2% of patients, portal inflammation was present, and 9.4% had cirrhosis. The amount of increase in liver enzymes bore no relationship with fibrosis, portal inflammation, and degree of steatosis. Conclusions The patients in our study showed a male predominancy and were somewhat younger than other studies.

    Full Text Available BACKGROUND: Morgellons is a poorly characterized constellation of symptoms, with the primary manifestations involving the skin. We conducted an investigation of this unexplained dermopathy to characterize the clinical and epidemiologic features and explore potential etiologies. METHODS: A descriptive study was conducted among persons at least 13 years of age and enrolled in Kaiser Permanente Northern California (KPNC during 2006-2008. A case was defined as the self-reported emergence of fibers or materials from the skin accompanied by skin lesions and/or disturbing skin sensations. We collected detailed epidemiologic data, performed clinical evaluations and geospatial analyses and analyzed materials collected from participants' skin. RESULTS: We identified 115 case-patients. The prevalence was 3.65 (95% CI = 2.98, 4.40 cases per 100,000 enrollees. There was no clustering of cases within the 13-county KPNC catchment area (p = .113. Case-patients had a median age of 52 years (range: 17-93 and were primarily female (77% and Caucasian (77%. Multi-system complaints were common; 70% reported chronic fatigue and 54% rated their overall health as fair or poor with mean Physical Component Scores and Mental Component Scores of 36.63 (SD = 12.9 and 35.45 (SD = 12.89, respectively. Cognitive deficits were detected in 59% of case-patients and 63% had evidence of clinically significant somatic complaints; 50% had drugs detected in hair samples and 78% reported exposure to solvents. Solar elastosis was the most common histopathologic abnormality (51% of biopsies; skin lesions were most consistent with arthropod bites or chronic excoriations. No parasites or mycobacteria were detected. Most materials collected from participants' skin were composed of cellulose, likely of cotton origin. CONCLUSIONS: This unexplained dermopathy was rare among this population of Northern California residents, but associated with significantly reduced health

    In this paper we comprehensively review published quantitative research on the relationship between religion, spirituality (R/S), and cardiovascular (CV) disease, discuss mechanisms that help explain the associations reported, examine the clinical implications of those findings, and explore future research needed in Brazil on this topic. First, we define the terms religion, spirituality, and secular humanism. Next, we review research examining the relationships between R/S and CV risk factors (smoking, alcohol/drug use, physical inactivity, poor diet, cholesterol, obesity, diabetes, blood pressure, and psychosocial stress). We then review research on R/S, cardiovascular functions (CV reactivity, heart rate variability, etc.), and inflammatory markers (IL-6, IFN-γ, CRP, fibrinogen, IL-4, IL-10). Next we examine research on R/S and coronary artery disease, hypertension, stroke, dementia, cardiac surgery outcomes, and mortality (CV mortality in particular). We then discuss mechanisms that help explain these relationships (focusing on psychological, social, and behavioral pathways) and present a theoretical causal model based on a Western religious perspective. Next we discuss the clinical applications of the research, and make practical suggestions on how cardiologists and cardiac surgeons can sensitively and sensibly address spiritual issues in clinical practice. Finally, we explore opportunities for future research. No research on R/S and cardiovascular disease has yet been published from Brazil, despite the tremendous interest and involvement of the population in R/S, making this an area of almost unlimited possibilities for researchers in Brazil.

    Objective To investigate the clinical features and management of bronchogenic cyst in the adults. Methods We retrospectively reviewed 50 patients admitted to our hospital with histopathologically proved bronchogenic cyst from January 1983 to December 2007. Of all the patients, 28 were male and 22 were female, with an average age of 36.9 (range, 18 to 64) years. The symptoms, location of the cysts, imaging evaluation, surgical treatment manner, and outcome of these patients were analyzed. Results Symptoms were present in 33 of the 50 patients, and cough was the most common symptom. Thirteen patients presented with complications: hemoptysis, infected cyst, dysphagia, paralysis, and hoarseness. The locations of the cysts included the mediastinum (28 cases), pulmonary parenchyma (12 cases), hilar area (3 cases), visceral pleura (1 case), and some rare locations including the intestinal mesentery (1 case), retroperitoneum (1 case), adrenal gland (1 case), neck (2 cases), and dura matter of the cervical vertebrae (1 case). Chest X-ray was performed in 36 patients and computed tomography (CT) was performed in 41 patients. The bronchogenic cyst in CT was characterized as a round, well circumscribed, unilocular mass, with density ranging from that of water to high density (0-50 Hu). As for treatment, complete resection of the bronchogenic cyst was performed in 47 (94%) patients, subtotal resection was performed in 3 (6%) patients. Open surgery was performed in 45 (90%) patients, and thoracoscopy (video-assisted thoracic surgery) was performed in 5 (10%) paitients. Of the 12 patients with intrapulmonary cyst, 11 patients underwent lobectomy and 1 patient underwent wedge resection. Postoperative sequelae occurred in 2 patients, 1 with persistent air leakage and 1 with hoarseness. All patients were proved with bronchogenic cyst pathologically. The average follow-up period was 6.5 years (range, 4 months to 10 years), and no late sequelae or recurrence of the cyst occurred

    AIM: To analyze the clinical and endoscopic features of Chinese patients with reflux esophagitis (RE).METHODS: A total of 1405 RE patients were analyzed retrospectively. Data on gender, age, presence/absence of H pylori infection and associated esophageal hiatal hernia were collected. Esophagitis was divided into different grades according to Los Angeles Classification.RESULTS: Of 18823 patients, 1405 were diagnosed as RE. The ratio of male to female patients was 1.75:1 (P < 0.01). The mean age of male and female patients was significantly different (P = 0.01). The peak age at onset of the disease was 40-60 years. According to Los Angeles Classification, there were significant differences in the age of patients with grades A and B compared to patients with grades C and D (P < 0.01). Two hundred and seventy-seven patients were infected with H pylori, the infection rate was low (P < 0.01). Complication of esophageal hiatal hernia was found to be significantly associated with the severity of esophagitis and age in 195 patients (P < 0.01). Esophageal mucosa damages were mainly located at the right esophageal wall.CONCLUSION: The peak age of onset of RE is 40-60 years and higher in males than in females. The mean age of onset of RE is lower in males than in females. The infection rate of H pylori is significantly decreased in patients with esophagitis. Old age and esophageal hiatal hernia are associated with more severe esophagitis. Right esophageal mucosal damage can occur more often in RE patients.

    The clinical presentation and radiological features were analyzed in 30 cases of syringomyelia associated with Chiari malformation. None of the patients had spinal dysraphism. The age on admission ranged from 6 to 59 years with a mean of 27 years. Syringomyelia was diagnosed by CT myelography and or MRI from 1982 to 1988. The initial symptoms were skeletal abnormality (43%) such as scolisis (12 cases) or pescavus (one case), unilateral pain or numbness (40%) and unilateral motor weakness (17%). Frequently seen signs on admission were sensory deficit (100%), scoliosis (57%), muscle weakness (57%), muscle atrophy (37%) and lower cranial nerve palsy (40%). The neurological findings were asymmetrical in all patients. The characteristic neurological findings in the cases presenting under 20 years of age were unilateral sensory and motor deficits (61%) with decreased or absent deep tendon reflex on the same side. The localization of the syrinx in axial section varied according to the level even in the same case. In 15 cases with unilateral sensory disturbance or unilateral sensory and motor deficit, the syrinx was located in the region corresponding to the posterolateral portion on the same side as that of sensory disturbance in the cervical or thoracic level. On the other hand, in 15 cases with bilateral sensory and motor deficit, the syrinx was located in the central portion and extended into the posterolateral portion of the more affected side. The authors think that the syrinx which originates from the unilateral posterolateral portion, extends to involve the gray matter around the central canal and the posterolateral portion of the other side with progression of the syrinx to cause bilateral disturbance. As a result, unilateral neurological symptoms also become bilateral with progression of the syrinx. (author).

    Full Text Available Arsenicosis is a multisystem disorder, with virtually no system spared from its vicious claw; though its predominant manifestations are linked to cutaneous involvement. Cutaneous effects take the form of pigmentary changes, hyperkeratosis, and skin cancers (Bowen′s disease, squamous cell carcinoma, and basal cell epithelioma. Peripheral vascular disease (blackfoot disease, hypertension, ischemic heart disease, noncirrhotic portal hypertension, hepatomegaly, peripheral neuropathy, respiratory and renal involvement, bad obstetrical outcome, hematological disturbances, and diabetes mellitus are among the other clinical features linked to arsenic toxicity. The effects are mediated principally by the trivalent form of arsenic (arsenite, which by its ability to bind with sulfhydryl groups present in various essential compounds leads to inactivation and derangement of body function. Though the toxicities are mostly linked to the trivalent state, arsenic is consumed mainly in its pentavalent form (arsenate, and reduction of arsenate to arsenite is mediated through glutathione. Body attempts to detoxify the agent via repeated oxidative methylation and reduction reaction, leading to the generation of methylated metabolites, which are excreted in the urine. Understandably the detoxification/bio-inactivation process is not a complete defense against the vicious metalloid, and it can cause chromosomal aberration, impairment of DNA repair process, alteration in the activity of tumor suppressor gene, etc., leading to genotoxicity and carcinogenicity. Arsenic causes apoptosis via free radical generation, and the cutaneous toxicity is linked to its effect on various cytokines (e.g., IL-8, TGF-β, TNF-α, GM-CSF, growth factors, and transcription factors. Increased expression of cytokeratins, keratin-16 (marker for hyperproliferation and keratin-8 and -18 (marker for less differentiated epithelial cells, can be related to the histopathological findings of

    This article discusses the evaluation of secondary care in the area of health surveillance. This was a descriptive and normative/evaluative study. Performance analysis drew on secondary data, based on a historical series of dental procedures conducted at the specialized dental clinics implemented in Brazil and recorded by the Outpatient Information System of the Unified National Health System (SIA/SUS) in 2007, as well as primary data from site visits to the clinics, based on questionnaires completed by clinic staff. Performance of the clinics was poor in most regions of the country, and the North of Brazil had the lowest percentage of specialty services implemented. The indicator "Performance of Secondary Care in Oral Health" was 64.4%. The type 3 specialty clinics showed better results in terms of performance and achievement of targets. The study showed the need to review the legal framework for implementing specialized dental clinics by adjusting the criteria and norms, as well as definition of new standards for achievement of goals in the evaluation and monitoring of these services.

    Full Text Available The present report aimed to perform a molecular epidemiological survey by investigating the presence of virulence factors in E. faecalis isolated from different human clinical (n = 57 and food samples (n = 55 in Porto Alegre, Brazil, collected from 2006 to 2009. In addition, the ability to form biofilm in vitro on polystyrene and the β-haemolytic and gelatinase activities were determined. Clinical strains presented a higher prevalence of aggregation substance (agg, enterococcal surface protein (esp and cytolysin (cylA genes when compared with food isolates. The esp gene was found only in clinical strains. On the other hand, the gelatinase (gelE and adherence factor (ace genes had similar prevalence among the strains, showing the widespread occurrence of these virulence factors among food and clinical E. faecalis strains in South Brazil. More than three virulence factor genes were detected in 77.2% and 18.2% of clinical and food strains, respectively. Gelatinase and β-haemolysin activities were not associated with the presence of gelE and cylA genes. The ability to produce biofilm was detected in 100% of clinical and 94.6% of food isolates, and clinical strains were more able to form biofilm than the food isolates (Student's t-test, p < 0.01. Results from the statistical analysis showed significant associations between strong biofilm formation and ace (p = 0.015 and gelE (p = 0.007 genes in clinical strains. In conclusion, our data indicate that E. faecalis strains isolated from clinical and food samples possess distinctive patterns of virulence factors, with a larger number of genes that encode virulence factors detected in clinical strains.

    Full Text Available There has been a resurgence in the number of pertussis cases in Brazil and around the world. Here, the genome of a clinical Bordetella pertussis strain (Bz181 that was recently isolated in Brazil is reported. Analysis of the virulence-associated genes defining the pre- and post-vaccination lineages revealed the presence of the prn2-ptxS1A-fim3B-ptxP3 allelic profile in Bz181, which is characteristic of the current pandemic lineage. A putative metallo-β-lactamase gene presenting all of the conserved zinc-binding motifs that characterise the catalytic site was identified, in addition to a multidrug efflux pump of the RND family that could confer resistance to erythromycin, which is the antibiotic of choice for treating pertussis disease.

Objectives: The goal of this study was to evaluate the clinical and demographic profile of patients with dementing disorders seen at a specialized outpatient clinic in South Brazil. Methods: A sample of 105 demented patients seen at the Dementia Outpatient Clinic from Hospital de Clínicas de Porto Alegre (HCPA, Brazil between June 2004 and June 2008. Evaluation of patients consisted of medical history, cognitive testing, assessment of functional status (Activities of Daily Living Scale - ADL; Instrumental Activities Daily Living - IADL and application of the Neuropsychiatry Inventory (NPI for behavioral symptoms. Severity of dementia was evaluated based on the CDR scale. All patients underwent laboratory screening tests and brain imaging exams to define etiology of dementia. Results: Of the whole sample, 71% were female. Age was 79±8 years (mean±SD. Educational level was 4±3 years (mean±SD. Sixty-four patients (60% presented the diagnosis of Alzheimer's disease. Of the whole sample, 26.7% were classified as CDR=1, 44% as CDR=2 and 29. 3% as CDR=3. A significant difference on the Mini Mental State Examination (MMSE and functional status scores was observed among the CDR categories (severity. No significant association was found between severity and impairment on memory tests and behavioral symptoms. Conclusions: Alzheimer's disease was the most common etiology, followed by vascular dementia. At diagnosis, most patients presented mild to moderate severity of dementia, independent of cause.

    BACKGROUND: Spinal muscular atrophy (SMA) is a kind of degenerative disease of nervous system. There are 4 types in clinic, especially types Ⅰ, Ⅱ and Ⅲ are common, and the researches on those 3 types are relative mature. Type Ⅳ is a kind of adult spinal muscular atrophy (ASMA), which has low incidence rate and is often misdiagnosed as amyotrophic lateral sclerosis, muscular dystrophy, cervical syndrome, or others.OBJECTIVE: To observe the clinical features of 46 ASMA patients and analyze the relationship between course and activity of daily living.DESIGN: Case analysis.SETTING: Departments of Neurology of the 81 Hospital of Chinese PLA, the Second Affiliated Hospital of Nanjing Medical College and General Hospital of Nanjing Military Area Command of Chinese PLA.PARTICIPANTS: A total of 46 ASMA patients were selected from the Departments of Neurology of the 81Hospital of Chinese PLA, the Second Affiliated Hospital of Nanjing Medical College and General Hospital of Nanjing Military Area Command of Chinese PLA between April 1998 and January 2002. All patients were consentient. Among 46 cases, there were 37 males and 9 females with the mean age of 42 years. The patients' courses in all ranged from 6 months to 23 years, concretely, courses of 37 cases were less than or equal to 5 years, and those of 9 cases were more than or equal to 6 years.METHODS : ① All the 46 ASMA patients were asked to check blood sedimentation, anti O, serum creatinine,creatine, blood creatine phosphokinase (CPK) and muscular biopsy as early as possible. ② X-ray was used to measure plain film of cervical vertebra borderline film of cranium and neck at proximal end of upper limb of 25 cases and plain film of abdominal vertebra at proximal end of lower limb of 17 cases.③ Cerebrospinal fluid of lumbar puncture was checked on 42 cases, for routine examination, biochemical examination, and immunoglobulin examination.

    Objective To identify features of clinical decision support systems critical for improving clinical practice. Design Systematic review of randomised controlled trials. Data sources Literature searches via Medline, CINAHL, and the Cochrane Controlled Trials Register up to 2003; and searches of reference lists of included studies and relevant reviews. Study selection Studies had to evaluate the ability of decision support systems to improve clinical practice. Data extraction Studies were assessed for statistically and clinically significant improvement in clinical practice and for the presence of 15 decision support system features whose importance had been repeatedly suggested in the literature. Results Seventy studies were included. Decision support systems significantly improved clinical practice in 68% of trials. Univariate analyses revealed that, for five of the system features, interventions possessing the feature were significantly more likely to improve clinical practice than interventions lacking the feature. Multiple logistic regression analysis identified four features as independent predictors of improved clinical practice: automatic provision of decision support as part of clinician workflow (P < 0.00001), provision of recommendations rather than just assessments (P = 0.0187), provision of decision support at the time and location of decision making (P = 0.0263), and computer based decision support (P = 0.0294). Of 32 systems possessing all four features, 30 (94%) significantly improved clinical practice. Furthermore, direct experimental justification was found for providing periodic performance feedback, sharing recommendations with patients, and requesting documentation of reasons for not following recommendations. Conclusions Several features were closely correlated with decision support systems' ability to improve patient care significantly. Clinicians and other stakeholders should implement clinical decision support systems that incorporate these

The analysis of clinical symptoms established a correlation of high titers of antibodies to cytomegalovirus (CMV and Epstein-Barr virus (EBV with symptoms, such as fever, arthritis, lymphadenopathy, carditis, hepatomegaly and erythema migrans eruption. However, having the similar clinical manifestations, CMV and EBV infections had some organ specificity. In SLE, concomitant comorbid infection, viral infection in particular, contributed to the development of the clinical picture polymorphism with the protracted, remitting inflammatory process and the inadequate efficiency of glucocorticoid and immunosuppressive therapy.

Aims - To determine the occurrence of Crohn's disease and ulcerative colitis in a Brazilian university hospital throughout a 20-year period, and analyze the demographical, clinical and evolutive features of these cases. Methods - The frequencies of new cases of Crohn's disease and ulcerative colitis admitted from January 1980 up to December 1999 were calculated and a descriptive analysis of the features of all cases seen from January 1990 up to December 1999 was performed. Results - A total of 257 new cases (126 with Crohn's disease and 131 with ulcerative colitis was recorded. The frequencies of admissions for both Crohn's disease and ulcerative colitis have increased progressively from 40 up to 61 cases/10.000 new admissions and Crohn's disease gradually became more common than ulcerative colitis. For both diseases, there was predominance of women, age at admission in the range of 30-40 years, Caucasian origin, married state and non-smokers. Digestive symptoms presented were similar to those already described for both diseases and there were no differences between Crohn's disease and ulcerative colitis regarding the frequencies of general complaints and extra-intestinal manifestations (29.5% vs 23.3%, including thromboembolism (5.9% vs 5.4%. Obstruction and/or perforation were seen in up to 59.2% of Crohn's disease cases, whereas 53.7% of all ulcerative colitis cases presented as severe forms. In Crohn

    Full Text Available BACKGROUND: The emergence of dengue throughout the tropical world is affecting an increasing proportion of adult cases. The clinical features of dengue in different age groups have not been well examined, especially in the context of early clinical diagnosis. METHODOLOGY/PRINCIPAL FINDINGS: We structured a prospective study of adults (≥ 18 years of age presenting with acute febrile illness within 72 hours from illness onset upon informed consent. Patients were followed up over a 3-4 week period to determine the clinical outcome. A total of 2,129 adults were enrolled in the study, of which 250 (11.7% had dengue. Differences in the rates of dengue-associated symptoms resulted in high sensitivities when the WHO 1997 or 2009 classification schemes for probable dengue fever were applied to the cohort. However, when the cases were stratified into age groups, fewer older adults reported symptoms such as myalgia, arthralgia, retro-orbital pain and mucosal bleeding, resulting in reduced sensitivity of the WHO classification schemes. On the other hand, the risks of severe dengue and hospitalization were not diminished in older adults, indicating that this group of patients can benefit from early diagnosis, especially when an antiviral drug becomes available. Our data also suggests that older adults who present with fever and leukopenia should be tested for dengue, even in the absence of other symptoms. CONCLUSION: Early clinical diagnosis based on previously defined symptoms that are associated with dengue, even when used in the schematics of both the WHO 1997 and 2009 classifications, is difficult in older adults.

    Full Text Available Primary hyperparathyroidism (PHPT is a clinical condition characterized by overactive parathyroid gland secretion of parathyroid hormone with concurrent alteration of the phosphocalcemic metabolism. We present a literature review on primary hyperparathyroidism addressing key on clinical presentation, causes, medical and surgical treatment at the best of our knowledge. Based on this review we confirm the role of serum calcium and serum level examination, as well as we define the definitive treatment for PHPT being parathyroidectomy. In case of contraindication for surgery, medical treatment can play a relevant role.

    2010-01-01

    Analysing human gait has found considerable interest in recent computer vision research. So far, however, contributions to this topic exclusively dealt with the tasks of person identification or activity recognition. In this paper, we consider a different application for gait analysis and examine its use as a means of deducing the physical well-being of people. The proposed method is based on transforming the joint motion trajectories using wavelets to extract spatio-temporal features which are then fed as input to a vector quantiser; a self-organising map for classification of walking patterns of individuals with and without pathology. We show that our proposed algorithm is successful in extracting features that successfully discriminate between individuals with and without locomotion impairment.

    This case was diagnosed as multiple cementoosseous dysplasia on the basis of clinical and radiological features but was diagnosed as ossifying fibroma on the basis of histopathological feature. The histopathologic features of the multiple cementoosseous dysplasia and cementoossifying fibroma have common features of cementum, fibrous network and bone. Multiple cementoosseous dysplasia is reactive lesion and shows restricted lesion size, occurred on anterior and posterior tooth of the mandible and needs no treatment except periodic follow up. But Cementoossifying fibroma is the true neoplasm and grows continuously and needs surgical removal. The final diagnosis of the multiple cementoosseous dysplasia requires good correlation of the clinical histopathological, and radiological features.

  8. Molecular identification of nocardia isolates from clinical samples and an overview of human nocardiosis in Brazil.

    Directory of Open Access Journals (Sweden)

    Paulo Victor Pereira Baio

    Full Text Available BACKGROUND: Nocardia sp. causes a variety of clinical presentations. The incidence of nocardiosis varies geographically according to several factors, such as the prevalence of HIV infections, transplants, neoplastic and rheumatic diseases, as well as climate, socio-economic conditions and laboratory procedures for Nocardia detection and identification. In Brazil the paucity of clinical reports of Nocardia infections suggests that this genus may be underestimated as a cause of human diseases and/or either neglected or misidentified in laboratory specimens. Accurate identification of Nocardia species has become increasingly important for clinical and epidemiological investigations. In this study, seven clinical Nocardia isolates were identified by multilocus sequence analysis (MLSA and their antimicrobial susceptibility was also determined. Most Nocardia isolates were associated to pulmonary disease. METHODOLOGY/PRINCIPAL FINDINGS: The majority of Brazilian human isolates in cases reported in literature were identified as Nocardia sp. Molecular characterization was used for species identification of Nocardia nova, Nocardia cyriacigeorgica, Nocardia asiatica and Nocardia exalbida/gamkensis. Data indicated that molecular analysis provided a different Nocardia speciation than the initial biochemical identification for most Brazilian isolates. All Nocardia isolates showed susceptibility to trimethoprim-sulfamethoxazole, the antimicrobial of choice in the treatment nocardiosis. N. nova isolated from different clinical specimens from one patient showed identical antimicrobial susceptibility patterns and two distinct clones. CONCLUSIONS/SIGNIFICANCE: Although Brazil is the world's fifth-largest country in terms of land mass and population, pulmonary, extrapulmonary and systemic forms of nocardiosis were reported in only 6 of the 26 Brazilian states from 1970 to 2013. A least 33.8% of these 46 cases of nocardiosis proved fatal. Interestingly, coinfection

    Full Text Available Erythema nodosum leprosum (ENL is a severe multisystem immune mediated complication of borderline lepromatous leprosy and lepromatous leprosy. ENL is associated with skin lesions, neuritis, arthritis, dactylitis, eye inflammation, osteitis, orchitis, lymphadenitis and nephritis. The treatment of ENL requires immunosuppression, which is often required for prolonged periods of time and may lead to serious adverse effects. ENL and its treatment is associated with increased mortality and economic hardship. Improved, evidence-based treatments for ENL are needed; however, defining the severity of ENL and outcome measures for treatment studies is difficult because of the multiple organ systems involved. A cross-sectional study was performed, by the members of the Erythema Nodosum Leprosum International STudy (ENLIST Group, of patients with ENL attending seven leprosy referral centres in Brazil, Ethiopia, India, Nepal, the Philippines and the United Kingdom. We systematically documented the clinical features and type of ENL, its severity and the drugs used to treat it. Patients with chronic ENL were more likely to be assessed as having severe ENL. Pain, the most frequent symptom, assessed using a semi-quantitative scale was significantly worse in individuals with "severe" ENL. Our findings will determine the items to be included in a severity scale of ENL which we are developing and validating. The study also provides data on the clinical features of ENL, which can be incorporated into a definition of ENL and used for outcome measures in treatment studies.

    2015-02-01

    Full Text Available Leprosy is a chronic disease caused by Mycobacterium leprae, highly incapacitating, and with systemic involvement in some cases. Renal involvement has been reported in all forms of the disease, and it is more frequent in multibacillary forms. The clinical presentation is variable and is determined by the host immunologic system reaction to the bacilli. During the course of the disease there are the so called reactional states, in which the immune system reacts against the bacilli, exacerbating the clinical manifestations. Different renal lesions have been described in leprosy, including acute and chronic glomerulonephritis, interstitial nephritis, secondary amyloidosis and pyelonephritis. The exact mechanism that leads to glomerulonephritis in leprosy is not completely understood. Leprosy treatment includes rifampicin, dapsone and clofazimine. Prednisone and non-steroidal anti-inflammatory drugs may be used to control acute immunological episodes.

    2015-11-01

    Synopsis Gluteal tendinopathy is now believed to be the primary local source of lateral hip pain, or greater trochanteric pain syndrome, previously referred to as trochanteric bursitis. This condition is prevalent, particularly among postmenopausal women, and has a considerable negative influence on quality of life. Improved prognosis and outcomes in the future for those with gluteal tendinopathy will be underpinned by advances in diagnostic testing, a clearer understanding of risk factors and comorbidities, and evidence-based management programs. High-quality studies that meet these requirements are still lacking. This clinical commentary provides direction to assist the clinician with assessment and management of the patient with gluteal tendinopathy, based on currently limited available evidence on this condition and the wider tendon literature and on the combined clinical experience of the authors.

    1988-01-01

    Three hundred and fifteen patients with anterior uveitis and juvenile chronic arthritis were reviewed in order to determine the incidence, visual prognosis, and the clinical characteristics of the intraocular inflammation. The overall incidence of uveitis was 20%. Approximately 25% of patients had relatively mild and/or transient involvement and an excellent visual prognosis. In 50% the uveitis was more severe but could be controlled with topical medication. In the remaining 25% the visual prognosis was poor due to the intractable nature of the uveitis and the subsequent development of vision-threatening complications. The majority of patients (74%) were under the age of 8 years when the uveitis was first diagnosed. Clinically, the intraocular inflammation was most frequently an asymptomatic, chronic, non-granulomatous, iridocyclitis which was bilateral in 71% of cases. Other ocular lesions, which were rare, included keratoconjunctivitis sicca and corneal melting.

    Full Text Available Hepatitis B virus (HBV has a low endemicity in Rio de Janeiro, Brazil. Sexual transmission must play an important role in this virus, but the prevalence and risk factors have never been properly investigated. The aim of this paper is to determine the prevalence and risk factors for HBV infection in patients attending a Sexually Transmitted Diseases Clinic of the Universidade Federal Fluminense, from the State of Rio de Janeiro, Brazil. In a retrospective study, HBV seroprevalence was investigated in 440 patients. Serum of each patient was assayed for antibodies against hepatitis B core antigen (anti-HBc, hepatitis B surface antigen (HBsAg and antibodies against hepatitis B surface antigen (anti-HBs. Demographic and risk factor data were extracted from clinic notes. The overall seroprevalence of exposure markers for HBV (anti-HBc, HBsAg and anti-HBs were 13%, 3.4% and 8.5% respectively. Homo/bisexual behaviour, anal intercourse, HIV infection, positive serology for syphilis and blood transfusion were predictors of the HBV exposure. Among demographic data, age and place of birth were associated with the anti-HBc seropositivity.

    With the objective to show the characteristics of neurocysticercosis (NCC) in Brazil, was performed a critical analysis of national literature which showed a frequency of 1.5% in autopsies and 3.0% in clinical studies, corresponding to 0.3% of all admissions in general hospitals. In seroepidemiological studies the positivity of specific reactions was 2.3%. Brazilian patient with NCC presents a general clinical-epidemilogical profile (31-50 years old man, rural origin, complex partial epileptic crisis, increased protein levels or normal CSF, CT showing calcifications, constituting the inactive form of NCC), and a profile of severity (21-40 years old woman, urban origin, vascular headache and intracranial hypertension, typical CSF syndrome of NCC or alteration of two or more CSF parameters, CT showing vesicles and/or calcifications, constituting the active form of NCC). Although two localities from the state of S o Paulo have 72:100000 and 96:100000/habitants as prevalence coefficients, regional and national prevalences are very underestimated. Some aspects related to underestimation of NCC prevalence in Brazil are discussed.

    One of the sequelae of chronic alcohol abuse is malnutrition. Importantly, a deficiency in thiamine (vitamin B(1)) can result in the acute, potentially reversible neurological disorder Wernicke encephalopathy (WE). When WE is recognized, thiamine treatment can elicit a rapid clinical recovery. If WE is left untreated, however, patients can develop Korsakoff syndrome (KS), a severe neurological disorder characterized by anterograde amnesia. Alcohol-related brain damage (ARBD) describes the effects of chronic alcohol consumption on human brain structure and function in the absence of more discrete and well-characterized neurological concomitants of alcoholism such as WE and KS. Through knowledge of both the well-described changes in brain structure and function that are evident in alcohol-related disorders such as WE and KS and the clinical outcomes associated with these changes, researchers have begun to gain a better understanding of ARBD. This Review examines ARBD from the perspective of WE and KS, exploring the clinical presentations, postmortem brain pathology, in vivo MRI findings and potential molecular mechanisms associated with these conditions. An awareness of the consequences of chronic alcohol consumption on human behavior and brain structure can enable clinicians to improve detection and treatment of ARBD.

    The clinical manifestations associated with H5N1 infection in humans range from asymptomatic infection to mild upper respiratory illness, severe pneumonia, and multiple organ failure. The ratio of symptomatic cases to asymptomatic cases is not known, because it is not possible to precisely define the number of asymptomatic cases. A total of 97 cases suffering from avian flu were suspected based on history taking, demographic data, clinical manifestations, laboratory and radiological investigations. The followings were done for all cases; complete blood picture (differential leucocytic count), coagulation profile, renal and liver function tests. H5N1 influenza virus was diagnosed thorough PCR technique. Changes in arterial blood gases and repeated chest X-rays were reported frequently. All patients were given specific antiviral therapy (oseltamivir). The study described the clinical picture and laboratory results of 81 confirmed avian influenza human cases in an Egyptian hospital (Abassia chest hospital), and reviewed the avian influenza current situation covering from March 2006 to June 2009 with very high pick in the first half of 2009. The significant apparent symptoms were fever as initial and main symptom (93.75%), followed by shortness of breathing (73%), cough (66.6%), muscle & joint pain (60%) and sore throat (40%).

    Introduction Data specific to late-life bipolar disorder (BD) are limited. Current research is sparse and present guidelines are not adapted to this group of patients. Objectives We present a literature review on clinical characteristics, comorbidities, and cognitive impairment in patients with late-life BD. This review discusses common comorbidities that affect BD elders and how aging might affect cognition and treatment. Methods Eligible studies were identified in MedLine by the Medical Subject Headings terms “bipolar disorder” and “aged”. We only included original research reports published in English between 2012 and 2015. Results From 414 articles extracted, 16 studies were included in the review. Cardiovascular and respiratory conditions, type II diabetes, and endocrinological abnormalities were observed as highly prevalent. BD is associated with a high suicide risk. Bipolar elderly had an increased risk of dementia and performed worse on cognitive screening tests compared to age-matched controls across different levels of cognition. Despite high rates of medical comorbidity among bipolar elderly, a systematic under-recognition and undertreatment of cardiovascular disease have been suggested. Conclusion There was a high burden of physical comorbidities and cognitive impairment in late-life BD. Bipolar elderly might be under-recorded and undertreated in primary medical care, indicating that this group needs an adapted clinical assessment and specific clinical guidelines need to be established.

    Sarcoidosis is a chronic multisystemic granulomatous disease of unknown etiology, characterized by the formation of noncaseating granulomas in the involved organs. Cutaneous involvement is about 25% with different clinical expressions, the lichenoid pattern being one of the rarest types of cutaneous sarcoidosis. Lichenoid sarcoidosis clinically manifests with multiple scale papules involving extensive skin areas, especially the trunk, limbs, and face mimicking a lichen planus. Although diverse histologic patterns have been previously related, a lichenoid granulomatous infiltrate involving the dermo-epidermal junction has never been reported in lichenoid sarcoidosis. We report a case of a 43-year-old woman presenting with skin-colored pruritic papules, slightly scaling in trunk, extremities, and ears. These symptoms condition continued to expand and worsen for several years. The patient was otherwise in good health with no lymphadenopathies. Histopathologic examination of a skin biopsy showed an upper dermal granulomatous infiltrate of epithelioid cells, without necrosis, distributed in a lichenoid pattern with many cytoid bodies. We consider this may be the first case presenting a characteristic microscopic granulomatous lichen-like pattern in the setting of a clinically lichenoid type of sarcoidosis.

    2011-09-01

    Full Text Available Aim: Macroprolactin is a high-molecular-weight form of prolactin. It has been suggested that macroprolactin has no clinical importance because of its decreased or limited bioactivity. Although screening for macroprolactinemia is recommended especially in patients with idiopathic hyperprolactinemia; recent studies reported that patients with macroprolactinemia may have some hyperprolactinemia symptoms. Currently, the causes of the symptoms as well as the treatment and follow-up of this group of patients are not clear. In our study, we aimed to retrospectively evaluate and compare the clinical characteristics and gonadal hormone levels of patients with macroprolactinemia and hyperprolactinemia.Materials and Methods: Forty patients with macroprolactinemia and 15 patients with hyperprolactinemia who referred to Obstetrics and Gynecology Hospital were examined.Results: We observed that the patients with macroprolactinemia had similar menstrual disturbances (oligomenorrhea/amenorrhea to the patients with hyperprolactinemia. There was no statistically significant difference between the two groups with respect to FSH, LH and estradiol levels. The frequencies of galactorrhea (p=0.002, headache (p=0.04 and positive radiological finding (p=0.001 were higher in patients with hyperprolactinemia. Infertility rate was found to be increased in women with macroprolactinemia (p=0.02.Conclusion: Patients with macroprolactinemia may have very similar clinic symptoms to those with hyperprolactinemia. Therefore, macroprolactin levels should be measured regardless of the symptoms of hyperprolactinemia in patients with elevated prolactin levels. Türk Jem 2011; 15: 62-5

    Muhammed Murtaza

    Full Text Available BACKGROUND: Morbidity associated with primary headache disorders is a major public health problem with an overall prevalence of 46%. Tension-type headache and migraine are the two most prevalent causes. However, headache has not been sufficiently studied as a cause of morbidity in the developing world. Literature on prevalence and classification of these disorders in South Asia is scarce. The aim of this study is to describe the classification and clinical features of headache patients who seek medical advice in Pakistan. METHODS AND RESULTS: Medical records of 255 consecutive patients who presented to a headache clinic at a tertiary care hospital were reviewed. Demographic details, onset and lifetime duration of illness, pattern of headache, associated features and family history were recorded. International Classification of Headache Disorders version 2 was applied. 66% of all patients were women and 81% of them were between 16 and 49 years of age. Migraine was the most common disorder (206 patients followed by tension-type headache (58 patients, medication-overuse headache (6 patients and cluster headache (4 patients. Chronic daily headache was seen in 99 patients. Patients with tension-type headache suffered from more frequent episodes of headache than patients with migraine (p<0.001. Duration of each headache episode was higher in women with menstrually related migraine (p = 0.015. Median age at presentation and at onset was lower in patients with migraine who reported a first-degree family history of the disease (p = 0.003 and p<0.001 respectively. CONCLUSIONS/SIGNIFICANCE: Patients who seek medical advice for headache in Pakistan are usually in their most productive ages. Migraine and tension-type headache are the most common clinical presentations of headache. Onset of migraine is earlier in patients with first-degree family history. Menstrually related migraine affects women with headache episodes of longer duration than other patients

    Full Text Available In June 2014, Suriname faced the first Chikungunya outbreak. Since international reports mostly focus on hospitalized patients, the least affected group, a study was conducted to describe clinical characteristics of mainly outpatients including children. In addition, the cumulative incidence of this first epidemic was investigated.During August and September 2014, clinically suspected Chikungunya cases were included in a prospective follow-up study. Blood specimens were collected and tested for viral RNA presence. Detailed clinical information was gathered through multiple telephone surveys until day 180. In addition, a three stage household-based cluster with a cross-sectional design was conducted in October, December 2014 and March 2015 to assess the cumulative incidence.Sixty-eight percent of symptomatic patients tested positive for Chikungunya virus (CHIKV. Arthralgia and pain in the fingers were distinctive for viremic CHIKV infected patients. Viremic CHIKV infected children (≤12 years characteristically displayed headache and vomiting, while arthralgia was less common at onset. The disease was cleared within seven days by 20% of the patients, while 22% of the viremic CHIKV infected patients, mostly women and elderly reported persistent arthralgia at day 180. The extrapolated cumulative CHIKV incidence in Paramaribo was 249 cases per 1000 persons, based on CHIKV self-reported cases in 53.1% of the households and 90.4% IgG detected in a subset of self-reported CHIKV+ persons. CHIKV peaked in the dry season and a drastic decrease in CHIKV patients coincided with a governmental campaign to reduce mosquito breeding sites.This study revealed that persistent arthralgia was a concern, but occurred less frequently in an outpatient setting. The data support a less severe pathological outcome for Caribbean CHIKV infections. This study augments incidence data available for first outbreaks in the region and showed that actions undertaken at the

The first attack occurred mainly in the months of June, July and December. The first metatarsophalangeal joint was affected in 59.7% of patients and the hand in 25%. Treatment changed over the follow- up period, with a decreased use of NSAIDs (p<0.0001 and an increased use of colchicine (p=0.015 and allopurinol (p<0.0001. In 9 (12.5% patients, joint aspiration was performed and monosodium urate crystals were found in synovial fluid or tophi. 42/72 (58.3% patients fulfilled a minimum of 6 clinical criteria of the American College of Rheumatology, necessary for gout diagnosis. 47/72 (65.3% patients, met the EULAR recommendations and had an 82% probability of being affected by gout. Conclusions: The diagnosis of gout is not always easy because of its changing clinical spectrum. Identification of MSU crystals in joint aspirates was obtained only in a minority of patients. In this setting the diagnosis with gout was often based on the observation of an acute intermittent monoarthritis involving mainly the first metatarsophlangeal joint, associated with hyperuricaemia and responsive to colchicine.

    Full Text Available Objective: This study was aimed to define the clinical and demographic findings of psoriasis in childhood. Methods: In this retrospective study, the data from 64 children with psoriasis admitted at the our dermatology clinic between January 2007 and January 2011 were included whose data were fully. Results: Of the patients, 37 (57.8% were boys and 27 (42.2% were girls. Mean age of the children was 10.08 ±3.98 years (3-16. In 10 (15% cases, a positive family history was detected. The most frequent localizations at onset were trunk (46.9%, scalp (28.1%, knee-elbow (10.9% and extremities (7.9%, respectively. The most commonly seen clinical types were plaque (68.8%, guttate (20.3%, palmoplantar (9.4%, pustular (1.6%, respectively. Nine children had nail involvement. Out of all patients, 21.9% had upper respiratory tract infections and 9.4% had emotional stres. Four cases were diagnosed with depression. Of the cases, two cases were on non-steroid anti-inflammatory medication, and 4 of them were on antibiotics. Systemic treatments were given to 21.9% of the cases besides topical treatments. Conclusion: The epidemiological studies of psoriasis during childhood period for different countries have been reported. In this study, the ratio shows differences when compared to those previous studies. There are few epidemiologic studies for Turkey. We believe that further epidemiological studies including large number of patients' groups will contribute the diagnosis and treatment of the disease.

    Full Text Available Background: The transition from fetal to neonatal life during birth is difficult for all babies. We aim to analyze the demography, clinical presentation, causes, and outcome of neurologically distressed newborns. Materials and Methods: We reviewed a total of 615 newborns files admitted with life threatening condition. Amongst them, 453 had presented neurological distress syndrome. Only cases with severe neurological impairment (Apgar Score System [ASS] ≤6 with no other associated injury were included in the study group. The study covered a period from January to December 2011 and located in pediatric intensive care unit. The information regarding clinical presentation, condition of birth, causes of distress, and outcome were analyzed. Neonate examination had been conducted by neonatologist and pediatric neurologist. Results: The sample included 272/453 (60.04% males and 181/453 (39.96% females. Newborns were aged from 1 to 14 days. The incidence of neurological distress amongst all admissions was 453/615 (73.65%. Clinical signs were weakness of primary reflexes (86.70%, non reactivity (78.19%, flaccid muscle tone (59.49% and impaired consciousness (32.29%. On Apgar score, 73 (20.68% had a score from 0 to 3; 234 (66.29% had a score 4-6 in the first minute of life. A total of 307 (86.97% newborns had been resuscitated at birth during the first five minutes. Death rate was 35.69%. Asphyxia (51.27% and neonatal infection (43.34% were the most common causes of death. Conclusion: These results show that much effort remains to be done in obstetric care, resuscitation management and improvement in neonatal infection care.

    We report six patients with partial, predominantly paramedian, tegmental pontine hemorrhages. Constant clinical manifestations consisted of: ipsilateral miosis, horizontal gaze paresis, lower motor neuron facial paresis, contralateral hemisensory loss and mild and transitory hemiparesis, dysarthria and mild or no compromise of consciousness. Five out of six were hypertensive. All patients survived with mild sequelae, oculomotor disturbances being the most persistent deficit. We found in our patients that a transverse diameter of less than 17 mm, unilaterality of the injury and absence of coma were the major indicators of a favorable outcome.

    Full Text Available Background: The forearm refractures are the most common and serious injuries in the childhood. In our practice the refractures in children occur from 1.3% up to 5.2% among all fractures in children. Clinical characteristics of the refractures were highlighted insufficiently. Purpose: To study clinical signs of forearm refractures and effect of osteoreparative process. Material and methods: In the department of children's trauma of Scientific Research Institute of Traumatology and Orthopedics during the period from 2002 to 2012 from the general number of the patients 136 children with refracture of the tubular bones were revealed. With regard to the number of fractures twice refractures were in 132 patients, three times refractures found in 4 patients. From these patients 102 were boys and 34 were girls. According to structure of refracture localization the forearm refractures were on the leading place, which were observed in 109 (80.1% of patients. The refractures of the middle third forearm were noted in 82 patients, the refracture of middle upper third forearm - in 2 patients, the refracture of the lower third forearm was in 25 patients. Results: In the refractures at the second stage of regeneration (time of occurrence more than 3 months, especially at the moment of active process of the callus ossification the close of medullar canal occur and hematoma volume became significantly less than in primary fracture. At refractures hematoma at the place of fracture was more localized. At the refracture the weak pain is defined, and sometimes pain can be absent (about the reasons is said above, and the main active and passive movements in the full volume. The cases of absence of crepitation are possible in refractures. It is important that in refractures the longitudinal and impacted displacement we did not observe. In cases with painless clinical course of the refracture in the patients the active and passive movements were saved in complete volume

    Central neurocytoma (CN) is a rare, benign brain tumor often located in the lateral ventricles. CN may cause obstructive hydrocephalus and manifest as signs of increased intracranial pressure. The goal of treatment for CN is a gross total resection (GTR), which often yields excellent prognosis with a very high rate of tumor control and survival. Adjuvant radiosurgery and radiotherapy may be considered to improve tumor control when GTR cannot be achieved. Chemotherapy is also not considered a primary treatment, but has been used as a salvage therapy. The radiological features of CN are indistinguishable from those of other brain tumors; therefore, many histological markers, such as synaptophysin, can be very useful for diagnosing CNs. Furthermore, the MIB-1 Labeling Index seems to be correlated with the prognosis of CN. We also discuss oncogenes associated with these elusive tumors. Further studies may improve our ability to accurately diagnose CNs and to design the optimal treatment regimens for patients with CNs.

    Purpose: To investigate the clinical characteristics and determine the effective surgical managements of A-pattern exotropia.Methods: Thirty-two patients with A-pattern exotropia underwent superior oblique muscle weakening procedures, medial rectus resection or (and) lateral rectus recession. Preand post-operative eye position, deviation angle, superior oblique function and binocular vision were examined and analyzed in the cases.Results: Overaction of the superior oblique muscles (31/32) and underaction of the medial rectus muscle (20/32) were presented in the cases. Postoperatively, a satisfactory ocular alignment was obtained in 28 cases (87.5%), and the A-pattern was corrected in 31 cases (96.9%). Four cases got binocular vision after surgery.Conclusions: As one of the most common forms of A and V patterns, A-pattern exotropia showed clinical characteristics of superior oblique muscle overaction and medial rectus muscle underacion, which should be the primary factors in the etiology of A-pattern exotropia, and superior oblique weakening procedures combined with horizontal surgery should be an effective approach to A-pattern exotropia treatment.

    Nontyphoid Salmonella is the most common bacterial pathogen causing gastrointestinal infection worldwide. Most nontyphoid Salmonella infection is limited to uncomplicated gastroenteritis that seldom requires antimicrobial treatment. Nevertheless, invasive infections, such as bacteremia, osteomyelitis, and meningitis, may occur and require antimicrobial therapy. Continuous genetic and genomic evolution in Salmonella leading to increased virulence and resistance to multiple drugs are of significant public health concern. Two major changes in the epidemiology of nontyphoid salmonellosis in Europe and in the USA occurred in the second half of the 20(th) century: the emergence of foodborne human infections caused by Salmonella enterica serotype Enteriditis and by multidrug-resistant strains of Salmonella enterica serotype Typhimurium. In the 21(st) century, a worsening situation is the increasing resistance to fluoroquinolones and third-generation cephalosporins in nontyphoid Salmonella. Clinical isolates showing carbapenem resistance also have been identified. Although antimicrobial therapy is usually not indicated for uncomplicated Salmonella gastroenteritis, recent studies indicated that a short-course ceftriaxone therapy (3-5 days) for patients with severe gastroenteritis would lead to a faster clinical recovery. Continuous surveillance of Salmonella in both humans and animals is mandatory. A better understanding of the mechanisms that lead to the emergence of antimicrobial resistance in Salmonella may help in the devising of better interventional strategies to reduce the spread of resistant Salmonella between humans and reservoirs along the food chain.

    Primary biliary cirrhosis (PBC), which is characterized by progressive destruction of intrahepatic bile ducts, is not a rare disease since both prevalence and incidence are increasing during the last years mainly due to the improvement of case finding strategies. The prognosis of the disease has improved due to both the recognition of earlier and indolent cases, and to the wide use of ursodeoxycholic acid (UDCA). New indicators of prognosis are available that will be useful especially for the growing number of patients with less severe disease. Most patients are asymptomatic at presentation. Pruritus may represent the most distressing symptom and, when UDCA is ineffective, cholestyramine represents the mainstay of treatment. Complications of long-standing cholestasis may be clinically relevant only in very advanced stages. Available data on the effects of UDCA on clinically relevant end points clearly indicate that the drug is able to slow but not to halt the progression of the disease while, in advanced stages, the only therapeutic option remains liver transplantation.

  18. Diagnosis and clinical features of trigemino-autonomic headaches.

    2013-10-01

    Although severe short-lasting headaches are rare, they can be considered disabling conditions with a major impact on the quality of life of patients. These headaches can divided broadly in to those associated with autonomic symptoms, so called trigeminal autonomic cephalgias (TACs), and those with few or no autonomic symptoms. The TACs include cluster headache, paroxysmal hemicranias, hemicrania continua, and short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms as well as short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing syndrome. In all of these syndromes, half-sided head pain and ipsilateral cranial autonomic symptoms such as lacrimation or rhinorrhea are prominent. The paroxysmal hemicranias have, unlike cluster headaches, a very robust response to indomethacin, leading to a notion of indomethacin-sensitive headaches. The diagnosis of TACs is exclusively a clinical task. Because of the fact that cluster headache is strictly half-sided, typically involves the region around the eye and temple and often starts in the upper jaw, most patients first consult a dentist or ophthalmologist. No single instrumental examination has yet been able to define, or ensure, the correct diagnosis, or differentiate idiopathic headache syndromes. It is crucial that a trained neurologist sees these patients early so that management can be optimized and unnecessary procedures can be avoided. Although TACS are, in comparison to migraine, quite rare, they are nevertheless clinically very important for the neurologist to consider as they are easy to diagnose and the treatment is very effective in most patients.

    Full Text Available Thalassemia is a type of hereditary anemia that predominantly affects individuals born in or descendents of countries bathed by the Mediterranean Sea, such as Italy and Greece. Also known as Cooley’s anemia and Mediterranean anemia, the disease causes alterations in hemoglobin formation and malformations of the cranium, long bones, maxilla and mandible. It presents two distinct clinical conditions: one severe, called “major” thalassemia, and the other mild, denominated “minor” thassalemia. Hematologic exam diagnoses the two forms of the disease. Its clinical and radiographic manifestations include hepatosplenomegalia, lymphadenopathy, augmented mandible, increase in medullary spaces, thick bone trabeculae and in lower quantity, resembling a “spider web”, displacement of the mandibular canal, with loss of detail of its superior and inferior corticals and a radiographic aspect of “hair standing on end” at the surface of the cranium. Some of these manifestations are so characteristic and capable of being observed in radiographs that they form part of the dentist’s routine. This case report discusses the alterations observed in the panoramic radiograph of a patient with thalassemia diagnosed by means of hematologic exam.

    Implant therapy has become a widely recognized treatment alternative for replacing missing teeth. Several long term follow-up studies have shown that the survival rate is high. However, complications may appear and risk indcators associated with early and late failures have been identified. The purpose of the present retrospective clinical study was to describe some clinical features of patients with clinical signs of peri-implantitis and to identify risk indicators of peri-implantitis in a population at a specialist clinic of Periodontology. In total,the material consisted of 377 implants in 111 patients with the diagnosis peri-implantitis. The mean age at the examination was found to be 56.3 years (range 22-83) for females and 64.1 years (range 27-85) for males. The mean number of remaining teeth was found to be 10.5 (S.D. 8.89) and the mean number of implants was 5.85 (S.D. 3.42). For a majority of the subjects, more than 50% of the remaining teeth had a marginal bone loss of more than 1/3 of the root length. Forty-sex percent of the patients visited regularly dental hygienists for supportive treatment. The percentage of implants with peri-implantitis was significantly increased for smokers compared to non-smokers (p = 0.04). In the group of non-smokers, 64% of the implants had the diagnosis peri-implantitis, while the corresponding relative frequency for smokers was 78%. A majority of the individuals had a Plaque index and Bleeding on probing index >50%. The median of the follow-up time after implant placement was 7.4 years and the observation period was not significantly correlated to the degree of bone loss around the implants. Among the subjects with a mean bone loss >6 mm at implants with peri-implantitis, more than 70% had a mean marginal bone loss > 1/3 of the root length of the remaining teeth. A positive and significant correlation was found between the degree of marginal bone loss in remaining teeth and the degree of bone loss around implants with peri

    Background Fanconi anemia is a severe congenital disorder associated with mutations in a cluster of genes responsible for DNA repair.Arriving at an accurate and timely diagnosis can be difficult in cases of Fanconi anemia with atypical clinical features.It is very important to increase the rate of accurate diagnosis for such cases in a clinical setting.The purpose of this study is to explore the clinical diagnosis of Fanconi anemia in children with atypical clinical features.Methods Six cases of Fanconi anemia with atypical clinical features were enrolled in the study,and their clinical features were recorded,their FANCA gene transcription was assessed by RT-PCR,and FANCA mutations and the ubiquitination of FANCD2 protein were analyzed using DNA sequencing and western blotting respectively.Results All six cases showed atypical clinical features including no apparent deformities,lack of response to immune therapy,and progressively increasing bone marrow failure.They also have significantly increased fetal hemoglobin,negative mitomycin-induced fracture test results,and carry a FANCA gene missense mutation.Single protein ubiquitination of FANCD2 was not observed in those patients.Conclusion The combination of clinical features,FANCA pathogenic gene mutation genotype and the absence of FANCD2 protein ubiquitination are helpful in the accurate and timely diagnosis of Fanconi anemia in children.

  2. Review of clinical and laboratory features of human Brucellosis

    2007-01-01

    Full Text Available Infection with Brucella spp. continues to pose a human health risk globally despite strides in eradicating the disease from domestic animals. Brucellosis has been an emerging disease since the discovery of Brucella melitensis by Sir David Bruce in 1887. Although many countries have eradicated B. abortus from cattle, in some areas B. melitensis and B. suis have emerged as causes of this infection in cattle, leading to human infections. Currently B. melitensis remains the principal cause of human brucellosis worldwide including India. The recent isolation of distinct strains of Brucella from marine mammals as well as humans is an indicator of an emerging zoonotic disease. Brucellosis in endemic and non-endemic regions remains a diagnostic puzzle due to misleading non-specific manifestations and increasing unusual presentations. Fewer than 10% of human cases of brucellosis may be clinically recognized and treated or reported. Routine serological surveillance is not practiced even in Brucella - endemic countries and we suggest that this should be a part of laboratory testing coupled with a high index of clinical suspicion to improve the level of case detection. The screening of family members of index cases of acute brucellosis in an endemic area should be undertaken to pick up additional unrecognised cases. Rapid and reliable, sensitive and specific, easy to perform and automated detection systems for Brucella spp. are urgently needed to allow early diagnosis and adequate antibiotic therapy in time to decrease morbidity / mortality. The history of travel to endemic countries along with exposure to animals and exotic foods are usually critical to making the clinical diagnosis. Laboratory testing is indispensable for diagnosis. Therefore alertness of clinician and close collaboration with microbiologist are essential even in endemic areas to correctly diagnose and treat this protean human infection. Existing treatment options, largely based on

    Fuchs' uveitis is very often diagnosed with substantial delay, which is at the origin of deleterious effects such as unnecessary treatment and its consequences. The aim of this study was to analyse the type and frequency of posterior inflammatory and fluorescein angiographic signs in Fuchs' uveitis in conjunction with other clinical signs. Patients seen at the Centre for Ophthalmic Specialised Care (COS) in Lausanne and the Memorial A. de Rothschild, Clinique Générale-Beaulieu in Geneva between 1995 and 2008 with the diagnosis of Fuchs' uveitis and who had undergone a fundus fluorescein angiography (FFA) were analysed. In addition to FFA signs, the data collected included age, gender, initial and final visual acuities, clinical findings at presentation, mean diagnostic delay and ocular complications. Between 1995 and 2008, 105 patients seen in our centres in Lausanne and Geneva were diagnosed with Fuchs' uveitis. Forty of them (38.1%) had undergone at least one FFA. One patient was excluded because of a concomittant diagnosis of multiple sclerosis. In 28 of 39 patients (71.2%) diagnosis was not reached at presentation with a mean diagnosis delay of 3.67 ± 4.86 years (range: 1 month-24 years). The original erroneous diagnosis was intermediate uveitis in 16 patients (57.1%), posterior uveitis in two patients (7.1%), panuveitis in four patients (14.3%) and anterior granulomatous uveitis in six patients (21.4%). Fluorescein angiography demonstrated the presence of disc hyperfluorescence in 43/44 eyes (97.7%), sectorial peripheral retinal vascular leaking in 6/44 eyes (13.6%) and cystoid macular oedema in 4/44 eyes (9.1%), all of which were seen in eyes having undergone cataract surgery. Fuchs' uveitis was bilateral in 5/39 patients (12.8%). The most frequent clinical signs were vitritis in 42/44 eyes (95.5%), stellate keratic precipitates in 41 eyes (93.2%), posterior subcapsular opacities or cataract in 19 eyes (43.2%), and heterochromia in 19 eyes (43.2%).

Current research is sparse and present guidelines are not adapted to this group of patients.Objectives: We present a literature review on clinical characteristics, comorbidities, and cognitive impairment in patients with late-life BD. This review discusses common comorbidities that affect BD elders and how aging might affect cognition and treatment.Methods: Eligible studies were identified in MedLine by the Medical Subject Headings terms “bipolar disorder” and “aged”. We only included original research reports published in English between 2012 and 2015.Results: From 414 articles extracted, 16 studies were included in the review. Cardiovascular and respiratory conditions, type II diabetes, and endocrinological abnormalities were observed as highly prevalent. BD is associated with a high suicide risk. Bipolar elderly had an increased risk of dementia and performed worse on cognitive screening tests compared to age-matched controls across different levels of cognition. Despite high rates of medical comorbidity among bipolar elderly, a systematic under-recognition and undertreatment of cardiovascular disease have been suggested.Conclusion: There was a high burden of physical comorbidities and cognitive impairment in late-life BD. Bipolar elderly might be under-recorded and undertreated in primary medical care, indicating that

    A retrospective study was conducted of the clinical records of 41 patients discharged from a hospital in Tarapoto, Peru, between August 1992 and June 1996 following treatment for Plasmodium falciparum malaria. Patients ranged in age from 18 to 65 years; 25 were male. The cases were uniformly distributed throughout the year. The duration of illness averaged 11 days. At admission, 40 patients had fever, 36 had shaking chills, 29 had headache, 21 had nausea and vomiting, 21 had hyporexia, 15 had pallor, and 13 had splenomegaly. 3 of the 16 women were pregnant. 7 patients reported a history of malaria. The admission diagnosis was malaria in 33 cases. 31 patients were treated with chloroquine; 18 were subsequently treated with pyrimethamine-sulfadoxin and 1 received doxycycline. No cases of grave illness or death occurred. The increasing presence of Plasmodium falciparum malaria in the Peruvian lowlands should promote review of the adequacy of control programs.

The study has shown that inattentive type of ADHD is noted in 50%, combined type in 38.3% and hyperactivity/impulsivity type in 11.7% of patients. Adult patients with ADHD also have a high level of anxiety and asthenic disorders. This study evaluated the efficacy and safety of adaptol in dosage 1500 mg daily during 8 weeks in the treatment of this group of patients. The high efficacy (improvement in 64,7% of cases) and safety of adaptol confirmed by the data of clinical, psychological and neurophysiological studies.

    The case a twenty year old patient is reported, whose chest X-ray demonstrated cardiomegaly with a prominent pulmonary segment. The echocardiographical examination indicated a single ventricle with septal rudiments; heart catherization confirmed the diagnosis of a single ventricle of the right ventricular type with a well-sized left ventricular outlet chamber and the banding of the pulmonary artery. In addition the case of a 17 year old patient is reported, whose chest X-ray demonstrated dextrocardia. Clinical manifestations (cyanosis, elevated hemoglobin, clubbing, 3rd heart sound) as well as one- and two-dimensional echocardiography with echocontrast media confirmed the diagnosis of corrected transposition of the great arteries, pulmonary stenosis and incompetence, single ventricle and dextrocardia, a diagnosis made already 12 years ago by heart catherization.

    To characterize the radiological and clinicopathologic features of cystic synovial sarcoma. Seven patients with primary cystic synovial sarcoma were evaluated. Computed tomography (CT) and magnetic resonance (MR) imaging were undertaken at the first presentation. The diagnosis of synovial sarcoma was made on the basis of histological examinations followed by molecular analysis. Radiological and clinicopathologic findings were reviewed. CT showed well-defined soft tissue mass without cortical bone erosion and invasion. Calcification was seen at the periphery of the mass in three cases. T2-weighted MR images showed multilocular inhomogeneous intensity mass in all cases, five of which showed fluid-fluid levels. On gross appearance, old and/or fresh hematomas were detected in six cases. In the one remaining case, microscopic hemorrhage in the cystic lumen was proven. Four cases had poorly differentiated areas. In five cases prominent hemangiopericytomatous vasculature was observed. Histologic grade was intermediate in one tumor and high in six. One case had a history of misdiagnosis for tarsal tunnel syndrome, one for lymphadenopathy, two for sciatica and two for hematoma. All cystic synovial sarcomas demonstrated multilocularity with well-circumscribed walls and internal septae. Synovial sarcoma should be taken into consideration in patients with deeply situated multicystic mass with triple signal intensity on T2-weighted MR imaging. (orig.)

    Bromelia antiacantha flowered from December to February and during this period the central leaves and bracts displayed a bright red colour. The inflorescence bears 150-350 flowers, with 10-35 flowers opening per day over 4-5 days. The flowers are dark magenta coloured with white margins, tubular-shaped with a wide opening, and their stigma is situated below the anthers. Anthesis began around 4:00 h and flowers lasted approximately 15 h. The highest nectar volume and sugar concentration occurred between 4:00-6:00 h; after this period, both decreased throughout the day. B. antiacantha is partially self-incompatible, non-autogamous, and therefore, pollinator dependent. The hummingbirds Thalurania glaucopis, Amazilia fimbriata, and Ramphodon naevius were its most frequent pollinators (55% of the visits), visiting flowers mainly in the afternoon. The scattered distribution of B. antiacantha promoted trap-lining behaviour of the hummingbirds, which favoured fruit set through xenogamy. Corolla colour, wide flower opening, sweet odour and concentrated nectar early in the day favoured bee visitation. Of the 38 % of bee visits, 96% were made by Bombus morio, mainly in the morning and their behaviour promoted self-pollination. The bee Trigona spinipes frequently acted as a pollen and nectar thief early in the morning, excluding most of the hummingbirds. Bromelia antiacantha has ornithophilous and melittophilous features, and despite being pollinated by two kinds of agents, its reproductive success depends on a given set of circumstances.

    Nineteen adults with brain tumors have been studied with positron emission tomography utilizing FDG. Fourteen had biopsy proven cerebral malignant glioma, one each had meningioma, hemangiopericytoma, primitive neuroectodermal tumor (PNET), two had unbiopsied lesions, and one patient had an area of biopsy proven radiation necrosis. Three different patterns of glucose metabolism are observed: marked increase in metabolism at the site of the known tumor in (10 high grade gliomas and the PNET), lower than normal metabolism at the tumor (in 1 grade II glioma, 3 grade III gliomas, 2 unbiopsied low density nonenhancing lesions, and the meningioma), no abnormality (1 enhancing glioma, the hemangiopericytoma and the radiation necrosis.) The metabolic rate of the tumor or the surrounding brain did not appear to be correlated with the history of previous irradiation or chemotherapy. Decreased metabolism was frequently observed in the rest of the affected hemisphere and in the contralateral cerebellum. Tumors of high grade or with enhancing CT characteristics were more likely to show increased metabolism. Among the patients with proven gliomas, survival after PETT scan tended to be longer for those with low metabolic activity tumors than for those with highly active tumors. The authors conclude that PETT may help to predict the malignant potential of tumors, and may add useful clinical information to the CT scan.

    Background. Frozen shoulder syndrome is a common musculoskeletal disease of idiopathic Parkinson's disease (PD) that causes long-term pain and physical disability. A better understanding of the associated factors can help identify PD patients who will require prevention to improve their quality of life. Methodology. This prospective study evaluated 60 shoulders of 30 PD patients. Correlation analysis was used to evaluate the relationships between clinical factors and shoulder sonography findings. Results. Frozen shoulder syndrome was found in 14 of 30 PD patients affecting 19 shoulders, including bilateral involvement in five and unilateral involvement in nine. There was a significant positive correlation between the parameters of sonography findings and frozen shoulder syndrome (i.e., thickness of bicipital effusion and tendon thickness of the subscapularis and supraspinatus) and mean ipsilateral Unified Parkinson's Disease Rating Scale (UPDRS) III and its subscores (tremor, rigidity, and bradykinesia scores). Conclusions. Higher ipsilateral UPDRS and subscores are associated with increased effusion around the biceps tendon, with increased tendon thickness of subscapularis and supraspinatus. Preventing frozen shoulder syndrome in the high-risk PD group is an important safety issue and highly relevant for their quality of life.

    Full Text Available BackgroundEndogenous hyperinsulinemic hypoglycemia (EHH is characterized by an inappropriately high plasma insulin level, despite a low plasma glucose level. Most of the EHH cases are caused by insulinoma, whereas nesidioblastosis and insulin autoimmune syndrome (IAS are relatively rare.MethodsTo evaluate the relative frequencies of various causes of EHH in Korea, we retrospectively analyzed 84 patients who were diagnosed with EHH from 1998 to 2012 in a university hospital.ResultsAmong the 84 EHH patients, 74 patients (88%, five (6%, and five (6% were diagnosed with insulinoma, nesidioblastosis or IAS, respectively. The most common clinical manifestation of EHH was neuroglycopenic symptoms. Symptom duration before diagnosis was 14.5 months (range, 1 to 120 months for insulinoma, 1.0 months (range, 6 days to 7 months for nesidioblastosis, and 2.0 months (range, 1 to 12 months for IAS. One patient, who was diagnosed with nesidioblastosis in 2006, underwent distal pancreatectomy but was later determined to be positive for insulin autoantibodies. Except for one patient who was diagnosed in 2007, the remaining three patients with nesidioblastosis demonstrated severe hyperinsulinemia (157 to 2,719 µIU/mL, which suggests that these patients might have had IAS, rather than nesidioblastosis.ConclusionThe results of this study suggest that the prevalence of IAS may be higher in Korea than previously thought. Therefore, measurement of insulin autoantibody levels is warranted for EHH patients, especially in patients with very high plasma insulin levels.

    This report describes a suicide case by acute arsenic intoxication via intravenous injection. A 30-year-old woman injected arsenic As (V) (sodium arseniate disodique: Disodium Hydrogena Arsenik RP) in a successful suicide attempt. Three hours following administration, the woman developed severe digestive symptoms. She was admitted to a hospital and transferred to the intensive care unit within 12 h of the massive administration of arsenic. Despite therapeutic efforts, over the next 2 h she developed multiorgan failure and died. A postmortem examination was performed. Pulmonary edema and congestion of liver were apparent. As (V) and As (III) were determined by high performance liquid chromatography and inductively coupled plasma mass spectrometry after mineralization of samples by concentrated nitric acid. Toxicological analysis revealed high concentrations of arsenic in biological fluids as well as in organs. Histopathological examination showed a typical indication of myocarditis. These findings were in agreement with acute arsenic poisoning. The symptoms developed by this young woman (intoxication by intravenous administration) were comparable to oral intoxication. The clinical signs, survival time, and administration type are discussed in light of the literature on acute and chronic arsenic poisoning.

    Human intestinal capillariasis is a rare parasitosis that was first recognized in the Philippines in the 1960 s. Parasitosis is a life threatening disease and has been reported from Thailand, Japan, South of Taiwan (Kaoh-Siung), Korea,Tran, Egypt, Italy and Spain. Its clinical symptoms are characterized by chronic diarrhea, abdominal pain,borborygmus, marked weight loss, protein and electrolyte loss and cachexia. Capillariasis may be fatal if early treatment is not given. We reported 14 cases living in rural areas of Taiwan. Three cases had histories of travelling to Thailand. They might have been infected in Thailand while stayed there. Two cases had the diet of raw freshwater fish before. Three cases received emergency laparotomy due to peritonitis and two cases were found of enteritis cystica profunda. According to the route of transmission,freshwater and brackish-water fish may act as the intermediate host of the parasite. The most simple and convenient method of diagnosing capillariasis is stool examination. Two cases were diagnosed by histology.Mebendazole or albendezole 200 mg orally twice a day for 20-30 d is the treatment of choice. All the patients were cured, and relapses were not observed within 12 mo.

    Full Text Available Background: Alopecia can be a manifestation of mycosis fungoides (MF; however, the prevalence is unknown. Aims: We sought to describe the clinicopathologic presentation of alopecia in patients with diagnosis of MF. Methods: A retrospective analysis of patients with biopsy-proven MF, who were evaluated at our cancer center from 2002 to 2012, was performed to identify patients with alopecia. Results: Five patients with alopecia were identified from reviewing of 157 patients with MF. The male:female ratio was 3:2, and the mean age of patients was 42.8 years. Two of these patients showed patchy hair loss on scalp which was clinically identical to alopecia areata. In remaining three patients, hair loss was seen in areas of MF lesions, and epidermal changes consisted of patch- and plaque-type lesions of MF, tumors, and follicular lesions (follicular MF were also present. In two of these patients, lymphadenopathy without any visceral involvement was detected. Conclusions: Alopecia was observed in 5 (3.18% patients with MF, which makes it a rare finding, which included alopecia areata-like patchy loss in 2 and alopecia within MF lesions in 3.

    Twenty-six, ten-week-old mink were infected by force feeding by pipette 2 ml of a tissue suspension containing a Wisconsin strain of mink enteritis virus. Four days later, diarrhea and partial or complete loss of appetite developed simultaneously in all of the animals. Squinting and occasional vomiting were also observed. By the sixth day after inoculation, all of the mink were anorectic and weak. Anorexia persisted for 48 to 96 hours. Diarrhea and vomiting continued until the eighth to ninth day after exposure. For the first two days after the appearance of diarrhea, the feces contained large quantities of mucus and intestinal casts were seen frequently in the droppings. Thereafter, the feces consisted mostly of yellowish green, watery fluid and contained no casts. Some of the animals died on the eighth day after infection. Those which survived were severely dehydrated and debilitated, but resumed eating and achieved complete clinical recovery within the next five to six days.Leukopenia, i.e., total leukocyte count of less than 5,000 cells per mm(3) of blood, was found in seven of nine mink examined during the height of the disease. Leukopenic animals were deficient in both lymphocytes and neutrophils.

    2016-03-01

    Vasculitic peripheral neuropathy (VPN) occurs due to ischemic changes of peripheral nerves, resulting from a deficit of vascular blood supply due to damaged vasa nervorum leading to vasculitis. VPN usually manifests as sensorimotor or sensory disturbances accompanied by pain, presenting as a type of multiple mononeuropathy, with a scattered distribution in distal limbs. VPN may also present as a mononeuropathy, distal symmetric polyneuropathy, plexopathy, or radiculopathy. The rapidity of VPN is variable, ranging from days to months, with symptoms occasionally changing with the appearance of new lesions. Careful history taking and neurological examination provides an exact diagnosis. The most common cause of VPN is primary vasculitis predominantly affecting small vessels, including vasa nervorum, anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, and polyarteritis nodosa. Similar vasculitic processes can also result from a systemic collagen disorder or secondary vasculitis. Electrophysiological studies and pathological investigation of biopsied peripheral nerves and muscles are important for diagnosis of vasculitis. Serological tests, including ANCA, are useful for diagnosis of vasculitis. Accurate neurological examinations are essential for diagnosis and evaluation of clinical course.

  18. Symptomatic cranial neuralgias in multiple sclerosis: clinical features and treatment.

    2012-02-01

    In multiple sclerosis, neuropathic pain is a frequent condition, negatively influencing the overall quality of life. Cranial neuralgias, including trigeminal, glossopharyngeal neuralgias, as well as occipital neuralgia, are typical expression of neuropathic pain. Neuralgias are characterised by paroxysmal painful attacks of electric shock-like sensation, occurring spontaneously or evoked by innocuous stimuli in specific trigger areas. In multiple sclerosis, demyelination in the centrally myelinated part of the cranial nerve roots plays an important role in the origin of neuralgic pain. These painful syndromes arising in multiple sclerosis are therefore considered "symptomatic", in contrast to classic cranial neuralgias, in which no cause other than a neurovascular contact is identified. At this time, the evidence on the management of symptomatic cranial neuralgias in multiple sclerosis is fragmentary and a comprehensive review addressing this topic is still lacking. For that reason, treatment is often based on personal clinical experience as well as on anecdotal reports. The aim of this review is to critically summarise the latest findings regarding the pathogenesis, the diagnosis, the instrumental evaluation and the medical as well as neurosurgical treatment of symptomatic trigeminal, glossopharyngeal and occipital neuralgia in multiple sclerosis, providing useful insights for neurologists and neurosurgeons and a broad range of specialists potentially involved in the treatment of these painful syndromes.

    Background An eruption cyst (EC) is a benign, developmental cyst associated with a primary or permanent tooth. This paper presents 66 ECs in 53 patients who reported to 3 different centers in Turkey between 2014-2015. Material and Methods 53 patients (31 male, 22 female) with 66 ECs were diagnosed and treated over a 1-year period. The mean age of patients was 5.4 years (minimum 5 months, maximum 11 years). Clinical examination and periapical radiographs were used to establish diagnosis. Age, gender, site, history of trauma and type of treatment were recorded. Results Of the 66 ECs diagnosed in 53 patients, more than half (56.6%) were located in the maxilla, with the maxillary first primary molars the teeth most commonly associated with ECs (30.3%). Multiple ECs were diagnosed in 13 of the 53 patients. ECs had previously diagnosed in the primary dentition of 2 patients, 3 patients reported a history of trauma to primary teeth. In the majority of patients (46 cases, 86.8%), no treatment was provided, whereas surgical treatment was provided in the remaining 7 cases (13.2%). Conclusions Eruption cysts are usually asymptomatic and do not require treatment;. however, if the cyst is symptomatic, it should be treated with simple surgical excision.

    BACKGROUND: As aging in elderly people, their brain tissue has degeneration and brain atrophy of different severity, and the volume of cranial cavity is relatively enlarged, it has greater compensatory ability to the space occupying lesion, and it is difficult to detect the meningioma because it grows to expand slowly, the tumor locates in non-functional region, and there are atypical symptoms and deficiency of localization signs.OBJECTIVE: To investigate the clinicopathologic features of senile meningiomas.DESIGN: A retrospective analysis.SETTING: Affiliated Hospital of Hebei University.PARTICIPANTS: Forty-nine elderly patients with meningioma were selected from the Department of Neurosurgery, Affiliated Hospital of Hebei University from May 1999 to March 2005, including 15 males and 34 females, 60 - 74 years of age, and they were all diagnosed by CT and MRI.METHODS: The sites of tumors were identified by CT and MRI examinations in all the patients. The tumors were partially or totally resected according to their own conditions. The types of the resected tumor were pathologically observed. The conditions of postoperative recovery were observed after 1, 3 and 6 months, and without new neurological dysfunction or complication was considered as good outcome.MAIN OUTCOME MEASURES: ① Sites and pathological types of the tumor; ② Postoperative outcomes and complications.RESULTS: All the 49 patients were involved in the analysis of results. ① The tumors had wide distributions with a main location in brain convexity. Among the 49 cases of meningioma, there were 25 cases of fibrocystic type, 12 cases of meningothelial type, 6 cases of psammomatous type, 4 cases of angiomatous type and 2 cases of microcystic type. ② Among the 49 patients, 35 had good outcome, 8 had self-care ability, 4 required care by others, 2 (4.1%) died postoperatively. No long-term complication related to the operation was observed during the follow-up postoperatively.CONCLUSION: Meningioma has

    2003-01-01

    Full Text Available The epidemiology, clinical picture and pathology of an outbreak of urolithiasis in cattle in southern Brazil are described. The disease occurred in August 1999 in a feedlot beef cattle herd. Five out of 1,100 castrated steers were affected. Clinical signs included colic and ventral abdominal distension. White, sand-grain-like mineral deposits precipitated on the preputial hairs. Affected cattle died spontaneously 24-48 hrs after the onset of the clinical signs. Only one animal recovered after perineal urethrostomy. Necropsy findings included calculi blocking the urethral lumen of the distal portion of the penile sigmoid flexure, urinary bladder rupture with leakage of urine into the abdominal cavity and secondary fibrinous peritonitis. Daily water intake was low since water sources were scarce and not readily available. The animals were fed rations high in grains and received limited amounts of roughage. Biochemical analysis revealed that the calculi were composed of ammonium phosphate. A calcium-phosphorus imbalance (0.4:0.6 was detected in the feedlot ration. For the outbreak, it is suggested that contributing factors to urolith formation include insufficient fiber ingestion, low water intake and high dietary levels of phosphorus. No additional cases were observed in that feedlot after preventive measures were established. Similar dietary mismanagement in fattening steers has been associated with obstructive urolithiasis in feedlot beef cattle in other countries.

    Full Text Available Objective  To deepen the understanding of 45,X/46,XY mixed gonadal dysgenesis (45,X/46,XY MGD by summarizing the respective clinical features of patients gathered from China, Brazil, Norway and Denmark suffering from the disease. Methods  Comparative analysis was done with the clinical data of 7 patients suffering from 45,X/46,XY MGD diagnosed in the PLA General Hospital of China, and that of other domestic and foreign (Brazil, Norway and Denmark cases summarized by Peking Union Medical College Hospital. Results  Most of the patients of 45,X/46,XY MGD presented the Turner's syndrome-like clinical manifestations such as short stature, multiple naevi on face and lower hair line, etc. Cardiovascular and renal malformation could be found in some patients with 45,X/46,XY MGD. Regarding to the external genitalia, 42.9% (n=27 of the patients were considered to be ambiguous, with a variety of gonadal expression. Laboratory tests demonstrated elevation of follicle-stimulating and/or luteinizing hormone levels with decreased sex hormone levels in most of the patients with 45,X/46,XY MGD. Recombinant human growth hormone (RhGH, testosterone, artificial menstrual cycle and prophylactic gonadectomy were used as primary treatment. There were differences between the domestic and foreign patients in the reason to visit the hospital, and in the age for diagnosis. Chinese patients were always hospitalized for growth retardation, while the foreign patients might go to a doctor for consultation due to various reasons, such as abnormal genitalia, infertility, and fetal chromosomal abnormalities, and many of them might also be diagnosed as 45,X/46,XY MGD in prenatal period or at birth. That was why the average diagnostic age was 4.7 years younger in foreign patients than in Chinese patients. Conclusions  No significant difference was found in the clinical characteristics of patients with 45,X/46,XY MGD among different countries and races. But the diagnostic

    Full Text Available Objective: To describe the frequency of popular myths about and features of asthma treatment in children and adolescents in an urban area in southern Brazil. Methods: The parents or legal guardians of public school students (8-16 years of age completed a specific questionnaire regarding their understanding of asthma, asthma control, and treatment characteristics. The sample included parents or legal guardians of students with asthma (n = 127 and healthy controls (n = 124. Results: The study involved 251 parents or legal guardians, of whom 127 (68.5% were the mothers and 130 (51.8% were White. The mean age of these participants was 38.47 ± 12.07 years. Of the participants in the asthma and control groups, 37 (29.1% and 26 (21.0%, respectively, reported being afraid of using asthma medications, whereas 61 (48% and 56 (45.2%, respectively, believed that using a metered dose inhaler can lead to drug dependence. However, only 17 (13.4% and 17 (13.7% of the participants in the asthma and control groups, respectively, reported being afraid of using oral corticosteroids. In the asthma group, 55 students (43.3% were diagnosed with uncontrolled asthma, only 41 (32.3% had a prescription or written treatment plan, and 38 (29.9% used asthma medications regularly. Conclusions: Popular myths about asthma treatment were common in our sample, as were uncontrolled asthma and inappropriate asthma management. Further studies in this field should be conducted in other developing countries, as should evaluations of pediatric asthma treatment programs in public health systems.

    Full Text Available Three patients (males, black, ages 37, 40 and 57 attended a university clinic with a progressive paraparesis of obscure origin. One patient who referred disease duration of more than 16 years, showed diminished deep reflexes, bilateral Babinski's sign, diminished sensation of vibration, abnormal bladder function and back pain. The other two patients (with one and six years of disease duration complained of weakness in one leg, increased deep reflexes and back pain. Babinski's sign and bladder disturbance were also present in the patient with six years of disease. Blood samples tested by an enzyme immune assay and a discriminatory Western blot were positive for HTLV-I. The familial analysis of one patient showed a possible pattern of sexual and vertical transmission of the virus. To the best of our knowledge, these are the first cases of a proven association between HTLV-I and TSP/HAM in Belem, Para, and emphasize the need to actively look for cases of neurological disease associated to the virus.Três pacientes (masculinos, negros, idades 37, 40 e 57 foram atendidos em uma clínica universitária com uma paraparesia progressiva de origem obscura.

    Modern healthcare is getting reshaped by growing Electronic Medical Records (EMR). Recently, these records have been shown of great value towards building clinical prediction models. In EMR data, patients' diseases and hospital interventions are captured through a set of diagnoses and procedures codes. These codes are usually represented in a tree form (e.g. ICD-10 tree) and the codes within a tree branch may be highly correlated. These codes can be used as features to build a prediction model and an appropriate feature selection can inform a clinician about important risk factors for a disease. Traditional feature selection methods (e.g. Information Gain, T-test, etc.) consider each variable independently and usually end up having a long feature list. Recently, Lasso and related l1-penalty based feature selection methods have become popular due to their joint feature selection property. However, Lasso is known to have problems of selecting one feature of many correlated features randomly. This hinders the clinicians to arrive at a stable feature set, which is crucial for clinical decision making process. In this paper, we solve this problem by using a recently proposed Tree-Lasso model. Since, the stability behavior of Tree-Lasso is not well understood, we study the stability behavior of Tree-Lasso and compare it with other feature selection methods. Using a synthetic and two real-world datasets (Cancer and Acute Myocardial Infarction), we show that Tree-Lasso based feature selection is significantly more stable than Lasso and comparable to other methods e.g. Information Gain, ReliefF and T-test. We further show that, using different types of classifiers such as logistic regression, naive Bayes, support vector machines, decision trees and Random Forest, the classification performance of Tree-Lasso is comparable to Lasso and better than other methods. Our result has implications in identifying stable risk factors for many healthcare problems and therefore can

    Mycosis fungoides is the most common type of cutaneous T-cell lymphoma (CTCL) and a rare disorder that typically affects older adults with erythematous scaling patches and plaques. Hypopigmented patches are a rare clinical variant of the disease. Granulomatous mycosis fungoides (GMF) is also a rare type of CTCL. No particular clinical criteria are available for the diagnosis of GMF, because of its variable presentations, and so the detection of GMF is primarily considered as a histopathological diagnosis. Rarely, a co-existence of more than one clinical or histopathological feature of mycosis fungoides may be present. To the best of our knowledge this is the first report of MF that shows the simultaneous co-existence of more than one clinical and histopathological variant of MF. We present a 29-year-old female with clinical presentations of both classic and hypopigmented mycosis fungoides (MF), and also the histopathological features of the classic and granulomatous types of the disease.

    Full Text Available The aim of this research was to understand the reasoning developed by medical students in a public university in Brazil. This research on education included semi-structured interviews and film recordings of interns discussing 10 clinical cases. A sample of 16 interns analyzed cases presented on a notebook computer with a webcam. They were instructed to verbalize all their thoughts on the procedures they would use. The film recordings and transcripts of the interviews were analyzed. Quantitative data was evaluated using Yates' chi-squared test and speech analysis was used to evaluate the transcripts. The theme worked on in the practice of reasoning was: the student's perceptions of their clinical practice. Of the 160 diagnoses, 57% were done with analytical reasoning and 43% with non-analytical reasoning. The hypothetical deductive method was employed by 31% of the interns and the inductive method was employed by 69%. The diagnostic accuracy was 81% correct for easy cases and 85% correct for difficult cases. We observed two empirical categories: the cognitive universe of the student and the patient's context.

    Full Text Available Purpose. To evaluate the prevalence and reasons for teeth extractions in a sample from a dental clinic in Brazil. Methods. The prevalence of teeth mortality was analyzed by gender, age, tooth type and reasons for extraction on 800 teeth of 439 subjects, whose data was collected in clinical records in a convenience sample. Results. The groups with range from 35 to 44 years, 45 to 54 years and 55 to 64 years revealed significantly greater number of teeth extractions than other age groups (P<0.0001. The anterior teeth loss increased significantly with aging, while the tooth mortality of premolar and molar were higher in younger people. The caries was the more prevalent reason for tooth mortality among young and adults up to 44 years old, while the periodontal disease was the main reason for extractions from 45 years old until range of 81 years (P<0.0001. Conclusions. It can be suggested that some reasons for tooth loss were age-dependent, but the caries and the periodontal diseases were the main reasons for tooth mortality in this Brazilian sample.

    Although clinicopathologic correlation is critical in the diagnosis of early mycosis fungoides (MF), how clinical information directly affects the pathologist's interpretation is unknown. This pilot study aimed to assess the influence of provided clinical information and specific histopathologic features on the histopathologic diagnosis of MF vs. its inflammatory simulants. A computerized survey recorded diagnostic impressions by 24 dermatopathologists of 30 hematoxylin-eosin stained images, including 15 MF images and 15 dermatitis images. Images were accompanied by concordant clinical descriptions (33%), no clinical information (33%) or discordant clinical descriptions (33%). Percentage of correctly classified MF histopathologic images for the three scenarios of concordant clinical information, no clinical information or discordant clinical information were 32% (kappa 0.19), 56% (kappa 0.12) and 16% (kappa 0.33), respectively. The percentage of correctly classified slides presented with no clinical information was different from the other two groups (p < 0.0001). Pautrier collections were most associated with correct classification. Clinical information may play a significant role in the histopathologic diagnosis of MF, although there may be some value in initial blinded histopathologic interpretation. Specific histopathologic features differ in relative importance in the diagnosis of MF.

    Full Text Available Abstract Background In Brazil, a Ministry of Health report revealed women who underwent an abortion were predominantly in the use of contraceptive methods, but mentioned inconsistent or erroneously contraceptive use. Promoting the use of contraceptive methods to prevent unwanted pregnancies is one of the most effective strategies to reduce abortion rates and maternal morbidity and mortality. Therefore, providing post-abortion family planning services that include structured contraceptive counseling with free and easy access to contraceptive methods can be suitable. So the objective of this study is to determine the acceptance and selection of contraceptive methods followed by a post-abortion family planning counseling. Methods A cross-sectional study was carried out from July to October 2008, enrolling 150 low income women to receive post-abortion care at a family planning clinic in a public hospital located in Recife, Brazil. The subjects were invited to take part of the study before receiving hospital leave from five different public maternities. An appointment was made for them at a family planning clinic at IMIP from the 8th to the 15th day after they had undergone an abortion. Every woman received information on contraceptive methods, side effects and fertility. Counseling was individualized and addressed them about feelings, expectations and motivations regarding contraception as well as pregnancy intention. Results Of all women enrolled in this study, 97.4% accepted at least one contraceptive method. Most of them (73.4% had no previous abortion history. Forty of the women who had undergone a previous abortion, 47.5% reported undergoing unsafe abortion. Slightly more than half of the pregnancies (52% were unwanted. All women had knowledge of the use of condoms, oral contraceptives and injectables. The most chosen method was injectables, followed by oral contraceptives and condoms. Only one woman chose an intrauterine device. Conclusion The

Amphotericin B had the lowest minimum inhibitory concentration for 90% of isolates (MIC90) value (2 μg/mL) and voriconazole had the highest (16 μg/mL). There was an association between a higher natamycin MIC and need for therapeutic penetrating keratoplasty (Mann–Whitney test, P < 0.005). Conclusion Trauma was the main risk factor, and therapeutic penetrating keratoplasty was necessary in 54% of patients. Amphotericin B had the lowest MIC90 (2 μg/mL) of the three antifungal agents tested. There was an association between higher natamycin MIC levels and corneal perforation, emphasizing the need for antifungal susceptibility testing and tailoring of antifungal strategies. PMID:24039389

    Full Text Available BACKGROUND: Dengue is a vector-borne disease in the tropical and subtropical region of the world and is transmitted by the mosquito Aedes aegypti. In the state of Amazonas, Brazil during the 2011 outbreak of dengue all the four Dengue virus (DENV serotypes circulating simultaneously were observed. The aim of the study was to describe the clinical epidemiology of dengue in Manaus, the capital city of the state of the Amazonas, where all the four DENV serotypes were co-circulating simultaneously. METHODOLOGY: Patients with acute febrile illness during the 2011 outbreak of dengue, enrolled at the Fundação de Medicina Tropical Dr. Heitor Viera Dourado (FMT-HVD, a referral centre for tropical and infectious diseases in Manaus, were invited to participate in a clinical and virological descriptive study. Sera from 677 patients were analyzed by RT-nested-PCRs for flaviviruses (DENV 1-4, Saint Louis encephalitis virus-SLEV, Bussuquara virus-BSQV and Ilheus virus-ILHV, alphavirus (Mayaro virus-MAYV and orthobunyavirus (Oropouche virus-OROV. PRINCIPAL FINDINGS: Only dengue viruses were detected in 260 patients (38.4%. Thirteen patients were co-infected with more than one DENV serotype and six (46.1% of them had a more severe clinical presentation of the disease. Nucleotide sequencing showed that DENV-1 belonged to genotype V, DENV-2 to the Asian/American genotype, DENV-3 to genotype III and DENV-4 to genotype II. CONCLUSIONS: Co-infection with more than one DENV serotype was observed. This finding should be warning signs to health authorities in situations of the large dispersal of serotypes that are occurring in the world.

    Biomedical big data, as a whole, covers numerous features, while each dataset specifically delineates part of them. "Full feature spectrum" knowledge discovery across heterogeneous data sources remains a major challenge. We developed a method called bootstrapping for unified feature association measurement (BUFAM) for pairwise association analysis, and relational dependency network (RDN) modeling for global module detection on features across breast cancer cohorts. Discovered knowledge was cross-validated using data from Wake Forest Baptist Medical Center's electronic medical records and annotated with BioCarta signaling signatures. The clinical potential of the discovered modules was exhibited by stratifying patients for drug responses. A series of discovered associations provided new insights into breast cancer, such as the effects of patient's cultural background on preferences for surgical procedure. We also discovered two groups of highly associated features, the HER2 and the ER modules, each of which described how phenotypes were associated with molecular signatures, diagnostic features, and clinical decisions. The discovered "ER module", which was dominated by cancer immunity, was used as an example for patient stratification and prediction of drug responses to tamoxifen and chemotherapy. BUFAM-derived RDN modeling demonstrated unique ability to discover clinically meaningful and actionable knowledge across highly heterogeneous biomedical big data sets.

    2016-11-22

    Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas can exhibit a wide spectrum of macroscopic and microscopic appearances. This not only causes occasional difficulties for the reporting pathologist in distinguishing these tumours from other lesions, but is also relevant clinically. As evidence accumulates, it becomes clear that multiple macroscopic and histological features of these neoplasms are relevant to the risk for malignant transformation and, consequently, of prime importance for clinical patient management. The need for detailed reporting is therefore increasing. This review discusses the panoply of gross and microscopic features of IPMN as well as the recommendations from recent consensus meetings regarding the pathology reporting on this tumour entity.

    Percutaneous Coronary Intervention (PCI) is the most common strategy for the treatment of Acute ST segment elevation Myocardial Infarction (STEMI), and thromboaspiration has been increasingly utilized for removal of occlusive thrombi. To analyze the influence of histopathological features of coronary thrombi in clinical outcomes of patients with STEMI, and the association of these variables with clinical, angiographic, and laboratory features and medications used in hospitalization. Prospective cohort study. All patients were monitored during hospitalization and thirty days after the event. Aspirated thrombi were preserved in formalin and subsequently stained with hematoxylin-eosin and embedded in paraffin. Thrombi were classified as recent and old. The primary outcome was the occurrence of major cardiovascular events within thirty days. During the study period, 1,149 patients were evaluated with STEMI, and 331 patients underwent thrombi aspiration, leaving 199 patients available for analysis. It was identified recent thrombi in 116 patients (58%) and old thrombi in 83 patients (42%). Recent thrombi have greater infiltration of red blood cells than old thrombi (p = 0.02), but there were no statistically significant differences between other clinical, angiographic, laboratory, and histopathological features and medications in both group of patients. The rates of clinical outcomes were similar in both groups. Recent thrombi were identified in 58% of patients with STEMI and it was observed an association with infiltration of red blood cells. There was no association between histopathological features of thrombi and clinical variables and cardiovascular outcomes.

Associated with rapidly progressive clinical deterioration, it usually results in death by the third year of life. The predominant MRI appearance is diffuse and symmetrical white matter disease. We discuss an atypical, late presentation of Canavan disease with a benign clinical course and uncharacteristic imaging features. This case introduces a previously unreported pattern of diffuse cortical abnormality without significant white matter involvement. (orig.)

    2013-01-01

    Several distinct clinical forms of mycosis fungoides have been described. Hypopigmented mycosis fungoides should be regarded as a subtype of mycosis fungoides, insofar as it presents some peculiar characteristics that contrast with the clinical features of the classical form. Most patients with hypopigmented mycosis fungoides are younger than patients typically diagnosed with classical mycosis fungoides. In addition to typical dark-skinned individuals impairment, hypopigmented mycosis fungoid...

    To determine whether the presence of melancholic features in hospitalized patients with major depressive disorder (MDD) was associated with specific clinical characteristics and treatment outcomes, supporting melancholic depression as a distinct subtype within MDD. 126 acutely ill inpatients with MDD were enrolled in an open, 6-week trial with fixed-dose fluoxetine 20mg daily. Symptom severity was assessed regularly, using the 17-item Hamilton Depression Rating Scale (HAMD-17) and Clinical Global Impression of Severity (CGI-S). Melancholic features were defined according to the DSM-IV criteria. Clinical variables were compared between patients with and without melancholic features. Generalized estimating equations method was used to explore the differences in HAMD-17 and CGI-S scores between the 2 groups over time. Clinical response was defined as having a 50% or greater reduction in HAMD-17 scores. 96 (76.2%) of the 126 patients with at least one post-baseline assessment met the criteria for melancholic depression. Melancholic depression differed from non-melancholic depression in clinical characteristics and predicted a better response to fluoxetine treatment. The differentiation between melancholic and non-melancholic depression within MDD hence is clinically significant and valid.

    Full Text Available We investigated flower morphology, nectar features, and hummingbird visitation to Palicourea crocea (Rubiaceae, a common ornithophilous shrub found in the riparian forest understory in the Upper Paraná River floodplain, Brazil. Flowers are distylous and the style-stamen dimorphism is accompanied by other intermorph dimorphisms in corolla length, anther length, and stigma lobe length and form. We did not observe strict reciprocity in the positioning of stigma and anthers between floral morphs. Flowering occurred during the rainy season, October to December. Nectar standing crop per flowerwas relatively constant throughout the day, which apparently resulted in hummingbirds visiting the plant throughout the day. Energetic content of the nectar in each flower (66.5J and that required daily by hummingbird visitors (up to 30kJ would oblige visits to hundreds of flowers each day, and thus movements between plants that should result in pollen flow. Three hummingbird species visited the flowers: the Gilded Sapphire (Hylocharis chrysura, the Black-throated Mango (Anthracothorax nigricollis, and the Glittering-bellied Emerald (Chlorostilbon aureoventris. The frequency of hummingbird visitation, nectar features, and the scarcity of other hummingbird-visited flowers in the study area, indicate that P. crocea is an important nectar resource for short-billed hummingbirds in the study site.Investigamos a morfologia floral, as características do néctar e a visita de beija-flores a Palicourea crocea (Rubiaceae, uma espécie ornitófila arbustiva comumente encontrada no sub-bosque da vegetação ripária na planície de inundação do Alto Rio Paraná, Brasil.

    2000-01-01

    Full Text Available Hantavirus pulmonary syndrome (HPS has been recognized recently in Brazil, where 28 cases have been reported as of September 1999. We report here the clinical and laboratory findings of three cases whose diagnoses were confirmed serologically. All the patients were adults who presented a febrile illness with respiratory symptoms that progressed to respiratory failure that required artificial ventilation in two of them. Laboratory findings were most of the time consistent with those reported in the United States in patients infected with the Sin Nombre virus, and included elevated hematocrit and thrombocytopenia; presence of atypical lymphocytes was observed in one patient. The chest radiological findings observed in all the patients were bilateral, diffuse, reticulonodular infiltrates. Two patients died. Histopathological examination of the lungs of these patients revealed interstitial and alveolar edema, alveolar hemorrhage, and mild interstitial pneumonia characterized by infiltrate of immunoblasts and mononuclear cells. In the epidemiologic investigation of one of the cases, serologic (ELISA tests were positive in 3 (25% out of 12 individuals who shared the same environmental exposure. HPS should be included in the differential diagnosis of interstitial pneumonia progressing to acute respiratory failure.

    Full Text Available Objective: Brucellosis became a remarkable disease in Kosovo. But there is not a comprehensive epidemiological study about epidemiology and clinical course of this disease from Kosovo. The aim of our study is to present demographic and clinical data of patients with brucellosis at University Clinical Center of Kosovo. Methods: A retrospective study was performed for the patients with brucellosis treated in our clinic during years 2011- 2012. The data about demography, history of the disease, clinical presentations, serological test, serum biochemistry and reatment were collected from hospital medical records. The diagnosis of brucellosis based on clinical and laboratory findings. Results: This descriptive study included 47 patients, who 33 of them (70.2% were males. The mean age was 37.9 ± 19.3 years. The route of transmission of the disease was known in 28 59.5% of them. Direct contact with livestock in 22 (46.8% and ingestion of dairy products in six cases (12.7% were reported as the transmission route. The majority of patients (27 patients, 57.4% were from rural area. The main presenting symptoms were atigue, fever and arthralgia. Osteoarticular manifestations were the common forms of localized disease. Regarding to the therapy, 45 (95.7% of patients were treated with streptomycin and doxycycline for the first three weeks. Conclusion: Human brucellosis is not a common in Kosovo but there is a potential risk. Osteoarticular symptoms were the most common presentation reasons. The most effective and preferred treatment regimen was Streptomycin plus Doxycycline for the first three weeks, and Doxycycline plus Rifampicin thereafter. J Microbiol Infect Dis 2015;5(4: 147-150

    Generalized anxiety disorder (GAD) is a prevalent and disabling disorder characterised by persistent worrying, anxiety symptoms, and tension. General practitioners and mental healthcare professionals frequently misdiagnose the presenting symptoms. This article addresses the clinical presentation of GAD and provides guidelines for discriminating GAD from other disorders, based on theoretical considerations and clinical experience. Debate relating to the validity of the definition of GAD is discussed, and suggestions are made for improving the criteria for GAD, which may guide future versions of classification systems such as the Diagnostic and Statistical Manual.

    Full Text Available Abstract Background The diagnosis of abdominal tuberculosis (TB is difficult, especially so in health care facilities in developing countries where laparoscopy and colonoscopy are rarely available. There is little information on abdominal TB in HIV infection. We estimated the prevalence and clinical features of abdominal (excluding genitourinary TB in HIV infected adults attending the University Teaching Hospital, Zambia. Methods We screened 5,609 medical inpatients, and those with fever, weight loss, and clinical features suggestive of abdominal pathology were evaluated further. A clinical algorithm was used to specify definitive investigations including laparoscopy or colonoscopy, with culture of biopsies and other samples. Results Of 140 HIV seropositive patients with these features, 31 patients underwent full evaluation and 22 (71% had definite or probable abdominal TB. The commonest presenting abdominal features were ascites and persistent tenderness. The commonest ultrasound findings were ascites, para-aortic lymphadenopathy (over 1 cm in size, and hepatomegaly. Abdominal TB was associated with CD4 cell counts over a wide range though 76% had CD4 counts Conclusion The clinical manifestations of abdominal TB in our HIV-infected patients resembled the well-established pattern in HIV-uninfected adults. Patients with fever, weight loss, abdominal tenderness, abdominal lymphadenopathy, ascites and/or hepatomegaly in Zambia have a high probability of abdominal TB, irrespective of CD4 cell count.

    Background Hereditary spastic paraplegia is a clinically and genetically heterogeneous group of neurodegenerative disorders of the motor system, characterized by slowly progressive spasticity and weakness of the lower extremities. This study was conducted to investigate the clinical features of hereditary spastic paraplegia with thin corpus callosum (HSP-TCC). Methods Clinical data from five patients and thirty-five previously published case reports of HSP-TCC were analyzed retrospectively. Results Most patients were adolescents at the onset of the disease, presenting with spastic paraparesis of the lower limbs and mental impairment. Some patients also had other clinical features, including spasticity of the upper limbs, cerebellar ataxia, and sensory disturbances. Cranial MRIs of the five patients revealed an extremely thin corpus callosum, sometimes with widened cerebral sulci and ventricles, as well as with cerebellar and cerebral atrophy. Conclusion The main clinical features of HSP-TCC include slowly progressive spastic paraplegia, mental impairment during the second decade of life, and an extremely thin corpus callosum as shown on cranial MRIs.

    Full Text Available Melanoma is an aggressive and rare neoplasm of melanocytic origin. Mucosal melanomas of the head and neck account for 1 % of neoplasms, 0,2–8,0 4 % of all melanomas and over 50 % of all mucosal melanomas. To date, in Russian and foreign literature only few retrospective series and case reports have been reported on mucosal melanoma. Despite melanoma’s common histological origin, head and neck mucosal melanoma presentation has some specific features due to its anatomical localization and poor clinical outcomes compared with those of cutaneous melanomas. Mucosal melanoma has a high metastatic potential. Five-year overall survival does not exceed 30 %. Advances in understanding of the clinical presentation can be used for prediction of behaviour and prognosis of this disease. We considered and analised articles devoted to clinical features of head and neck mucosal melanoma according to its localization.

    Full Text Available Background: In 1966, the Gaffrée and Guinle University Hospital – GGUH was incorporated into the Federal University of the State of Rio de Janeiro – UNIRIO. Since then the Homeopathy clinic has had it's service there. Since the creation of medical residency in Homeopathy in 2004, there has been a significant increase of treatment in the number of patients and also a significant increase in the inter-relationship with other specialists and hospital services. A wide variety of patients have been treated at the GGUH on a daily basis. Many patients have been examined and treated with homeopathy alone, while others were also examined in other specialties, making homeopathic treatment an adjunct to classical therapy and vice versa. Given the expressive number of medical consultations (around 2500/year, this outstanding result in our clinical and academic practice has created the relevance and need for the verification of the epidemiological profile of these patients. Epidemiological studies are needed to clearly show the population included in this hospital, which is considered to be a reference in the Brazilian Health System (SUS. Aims: To demonstrate the epidemiological and clinical homeopathic profile in the ambulatory of homeopathy at the Gaffrée and Guinle University Hospital (GGUH of the Federal University of the Staate of Rio de Janeiro - UNIRIO, Brazil. Methodology: Cross-sectional study of 140 medical records randomly selected from the ambulatory of homeopathy at GGUH. The sample represents 50% of the monthly average of the clinical service from January to October 2009. The medical records incorrectly completed for the data analysis were excluded. Microsoft Office Excel 2007 used to data collection and analysis. Results and Discussion: A total of 100 records were selected for analysis (71.4%.

    Invasive pneumococcal disease is a relevant public health problem in Brazil, especially among children and the elderly. In July/2010 a 10-valent pneumococcal conjugate vaccine was introduced to the immunization schedule of Brazilian children under two years of age. Between July/2010 and December/2013 we conducted a case-series study on invasive pneumococcal disease in Salvador, Brazil to describe the clinical and bacteriological profile of invasive pneumococcal disease cases during the post-implementation period. Eighty-two cases were eligible. Mean age was 31 years (interquartile range, 3-42); 17.1% and 30.5% were under 2 years and 5 years, respectively. Pneumococcal meningitis (n=64, 78.1%), bacteraemic pneumococcal pneumonia (n=12, 14.6%) and bacteraemia (n=6, 7.3%) were the clinical syndromes identified. Thirty-three different serotypes were found. Of these, serotype 14 (n=12, 14.6%) was the most common, followed by 23F (n=10, 12.2%), 12F (n=8, 9.8%), 18C (n=5, 6.1%) and 6B (n=5, 6.1%). Investigations conducted in Salvador in the pre-vaccine period did not identify serotype 12F as one of the most prevalent serotypes. Increase of serotype 12F was observed in different regions of Brazil, in the post-vaccine period. Among children under two years of age, the target group for 10-valent pneumococcal conjugate vaccine, 11 (78.6%) of the 14 isolated strains of Streptococcus pneumoniae belonged to vaccine serotypes; at least 50% of these children were not vaccinated. The relatively recent implementation of 10-valent pneumococcal conjugate vaccine in Brazil reinforces the need to maintain an active surveillance of invasive pneumococcal disease cases, considering the possible increase of invasive pneumococcal disease cases related to non-vaccine serotypes and the changes on the clinical presentation of the disease.

    A total of 124 Cryptococcus isolates, including 84 clinical strains obtained from cerebrospinal fluid from AIDS patients and 40 environmental isolates from pigeon excreta and from Eucalyptus trees, were studied. The varieties, serotypes, phospholipase activity and molecular profile of these isolates were determined. Cryptococcus neoformans var. grubii serotype A was identified in 120 isolates and Cryptococcus gattii serotype B in four isolates. The clinical isolates showed higher phospholipase activity than environmental isolates. Similar patterns of in vitro susceptibility to amphotericin B, fluconazole, itraconazole and voriconazole and no resistance were found for all isolates. Molecular type VNI (C. neoformans var. grubii) was recovered in 80 clinical and 40 environmental isolates while the type VGIII (C. gattii) was found in four clinical isolates. This study demonstrated for the first time the molecular types of clinical and environmental Cryptococcus isolates in the midwest Brazil region.

    Full Text Available Brucellosis is a zoonotic infection and has endemic characteristics. Neurobrucellosis is an uncommon complication of this infection. The aim of this study was to present unusual clinical manifestations and to discuss the management and outcome of a series of 18 neurobrucellosis cases. Initial clinical manifestations consist of pseudotumor cerebri in one case, white matter lesions and demyelinating syndrome in three cases, intracranial granuloma in one case, transverse myelitis in two cases, sagittal sinus thrombosis in one case, spinal arachnoiditis in one case, intracranial vasculitis in one case, in addition to meningitis in all cases. Eleven patients were male and seven were female. The most prevalent symptoms were headache (83% and fever (44%. All patients were treated with rifampicin, doxycycline plus trimethoprim-sulfamethoxazole or ceftriaxone. Duration of treatment (varied 3-12 months was determined on basis of the CSF response. In four patients presented with left mild sequelae including aphasia, hearing loss, hemiparesis. In conclusion, although mortality is rare in neurobrucellosis, its sequelae are significant. In neurobrucellosis various clinical and neuroradiologic signs and symptoms can be confused with other neurologic diseases. In inhabitants or visitors of endemic areas, neurobrucellosis should be kept in mind in cases that have unusual neurological manifestations.

All patients were treated with rifampicin, doxycycline plus trimethoprim-sulfamethoxazole or ceftriaxone. Duration of treatment (varied 3-12 months) was determined on basis of the CSF response. In four patients presented with left mild sequelae including aphasia, hearing loss, hemiparesis. In conclusion, although mortality is rare in neurobrucellosis, its sequelae are significant. In neurobrucellosis various clinical and neuroradiologic signs and symptoms can be confused with other neurologic diseases. In inhabitants or visitors of endemic areas, neurobrucellosis should be kept in mind in cases that have unusual neurological manifestations.

    Full Text Available Background: The assessment of patient clinical outcome focuses on measuring various aspects of the health status of a patient who is under healthcare intervention. Patient clinical outcome assessment is a very significant process in the clinical field as it allows health care professionals to better understand the effectiveness of their health care programs and thus for enhancing the health care quality in general. It is thus vital that a high quality, informative review of current issues regarding the assessment of patient clinical outcome should be conducted. Aims & Objectives: 1 Summarizes the advantages of the assessment of patient clinical outcome; 2 reviews some of the existing patient clinical outcome assessment models namely: Simulation, Markov, Bayesian belief networks, Bayesian statistics and Conventional statistics, and Kaplan-Meier analysis models; and 3 demonstrates the desired features that should be fulfilled by a well-established ideal patient clinical outcome assessment model. Material & Methods: An integrative review of the literature has been performed using the Google Scholar to explore the field of patient clinical outcome assessment. Conclusion: This paper will directly support researchers, clinicians and health care professionals in their understanding of developments in the domain of the assessment of patient clinical outcome, thus enabling them to propose ideal assessment models.

    Aim: Nodular regenerative hyperplasia (NRH) and large regenerative nodules (LRN) are distinct types of hepatocellular nodules that have been confused in the radiology literature. However, distinction is critical because their clinical significance is quite different. Our purpose was to review the clinical and imaging findings in a series of patients with NRH and LRN in order to identify distinguishing clinical and imaging features. Materials and methods: This was a retrospective case series. The clinical and imaging features were compared in 36 patients with pathological proof of NRH and 23 patients with pathological evidence of LRN. Results: NRH and LRN have different predisposing factors and imaging findings. NRH is often associated with organ transplantation, myeloproliferative disease, or autoimmune processes. Livers with NRH typically do not have enhancing nodules; none of the present patients with NRH had enhancing liver masses. In contrast, LRN are often associated with Budd-Chiari syndrome. Enhancing liver masses were noted in 19 (83%) of the 23 patients with LRN. The p values for the comparisons were less than 0.001 for both enhancing liver masses and hepatic vein thrombosis. Conclusion: NRH and LRN can have distinct clinical presentations and imaging appearances. LRN often result in enhancing liver nodules, whereas NRH usually does not. Clinical and imaging information enables the distinction of LRN and NRH in many cases.

    Mitochondrial encephalopathy with lactic acidosis and stroke-like episodes (MELAS) mostly occur in children. The point mutation A3243G of mitochondrial DNA (mtDNA) may work as a specific bio-marker for mitochondrial disorders. The related clinical features, however, may vary among individuals. This study therefore investigated the relation between MELAS clinical features and point mutation A3243G of mtDNA, in an attempt to provide further evidences for genetic diagnosis of MELAS. Children with MELAS-like syndromes were tested for both blood lactate level and point mutation A3243G of mtDNA. Further family study was performed by mtDNA mutation screening at the same loci for those who had positive gene mutation at A3243G loci. Those who were negative for A3243G point mutation were examined by muscle biopsy and genetic screening. Both clinical and genetic features were analyzed. In all 40 cases with positive A3243G mutation, 36 children fitted clinical diagnosis of MELAS. In other 484 cases with negative mutation, only 8 children were clinically diagnosed with MELAS. Blood lactate levels in both groups were all elevated (P>0.05). In a further genetic screening of 28 families, 10 biological mothers and 8 siblings of MELAS children had positive A3243G point mutations but without any clinical symptoms. Certain difference existed in the clinical manifestations between children who were positive and negative for A3243G mutation of mtDNA but without statistical significance. MELAS showed maternal inheritance under most circumstances.

    The historical and clinical findings in 200 referred cases of equine sinus disease were reviewed retrospectively. Univariable and multivariable analyses were performed to detect significant differences in historical or clinical features between various categories of sinus disease. The causes of sinus disease were classified as subacute primary (less than two months duration) (n=52), chronic primary (more than two months duration) (n=37), dental (n=40), sinus cyst (n=26), traumatic (n=13) or mycotic sinusitis (n=7), sinus neoplasia (n=10), dental-related oromaxillary fistula (n=8) and intrasinus progressive ethmoid haematoma (n=7). The majority of sinus disorders were of chronic duration at the time of referral and most (including 97 per cent of chronic primary sinusitis cases) had not responded to previous antibiotic therapy and/or sinus lavage in some cases. Clinical signs included unilateral nasal discharge in most cases, including purulent or mucopurulent discharge in all horses with primary, dental and mycotic sinusitis. Haemorrhagic nasal discharge was a feature of traumatic sinusitis and intrasinus progressive ethmoid haematomas. Firm facial swellings and nasal airflow obstruction were features of sinus cysts and neoplasms. Ipsilateral lymphadenitis was a more prominent feature of sinus disease with active infections such as primary, dental or mycotic sinusitis.

    We report a patient who presented with clinical and MRI findings suggestive of polymyositis but, in whom, muscle biopsy disclosed a strikingly different diagnosis. A 65-year-old woman presented with 3-week history of bilateral proximal muscle pain and weakness. Laboratory investigations showed markedly elevated inflammatory markers and mildly elevated muscle enzymes. MRI scans of lower limbs showed features suggestive of polymyositis. However, muscle biopsy showed features of a polyarteritis-type vasculitis affecting an intramuscular blood vessel. Our reports highlight the critical role of muscle biopsy in establishing the correct diagnosis in patients with suspected myositis.

    Aim: The aim of work was presentation of several socio-demographic, clinical and laboratory characteristics of gastroenteritis caused by rotavirus. The examinees and methods: The examinees were children under the age of five years treated at the Pediatric Clinic due to acute gastroenteritis caused by rotavirus. Rotavirus is isolated by method chromatographic immunoassay by Cer Test Biotec. Results: From the total number of patients (850) suffering from acute gastroenteritis, feces test on bacteria, viruses. protozoa and fungi was positive in 425 (49.76%) cases. From this number the test on bacteria was positive in 248 (58.62%) cases, on viruses it was positive in 165 (39.0%), on protozoa in 9 (2.12%) cases and on fungi only one case. Rotavirus was the most frequent one in viral test, it was isolated in 142 (86.06%) cases, adenoviruses were found in 9 (5.45%) cases and noroviruses in only one case. The same feces sample that contained rotavirus and adenoviruses were isolated in five cases, whereas rotavirus with bacteria was isolated in the same feces sample in five cases. The biggest number of cases 62 (43.66%) were of the age 6-12 months, whereas the smallest number 10 (7.04%) cases were of the age 37-60 months. There were 76 (53.52%) of cases of male gender, from rural areas there were 81 (57.04%) cases and there were 58 (40.80%) cases during the summer period. Among the clinical symptoms the most prominent were diarrhea, vomiting, high temperature, whereas the different degree of dehydration were present in all cases (the most common one was moderate dehydration). The most frequent one was isonatremic dehydration in 91 (64.08%) cases, less frequent one was hypernatremic dehydration in 14 (9.85%) cases. The majority of cases (97.89%) had lower blood pH values, whereas 67 (47.17%) cases had pH values that varied from 7.16 -7.20 (curve peak), normal values were registered in only 3 (2.11%) cases. Urea values were increased in 45 (31.07%) cases (the maximum value

    Full Text Available The article describes a clinical case of organic depressive disorder in the personality who sustained a traumatic brain injury and who abused alcohol, with distinguishing number of clinical and psychopathological features. Depressed mood, slowed thinking process, sleep disturbances, low self-esteem, hypochondriacal tendencies allowed to diagnose depressive disorder. Clinical history on sustained brain concussion, as well as inertness of nervous and mental processes revealed in psychodiagnostic study testified to organic genesis of the disease. Alcohol abuse by the person having an adverse organic background contributed to appearance of psychotic symptoms in clinical picture. Hallucinatory and delusional inclusions relatively quickly stopped on a background of antipsychotic treatment; this testified that they are secondary to the affective (depressive symptoms.

    Full Text Available Copy number variations involving the 17q12 region have been associated with developmental and speech delay, autism, aggression, self-injury, biting and hitting, oppositional defiance, inappropriate language, and auditory hallucinations. We present a tall-appearing 17-year-old boy with marfanoid habitus, hypermobile joints, mild scoliosis, pectus deformity, widely spaced nipples, pes cavus, autism spectrum disorder, intellectual disability, and psychiatric manifestations including physical and verbal aggression, obsessive-compulsive behaviors, and oppositional defiance. An echocardiogram showed borderline increased aortic root size. An abdominal ultrasound revealed a small pancreas, mild splenomegaly with a 1.3 cm accessory splenule, and normal kidneys and liver. A testing panel for Marfan, aneurysm, and related disorders was negative. Subsequently, a 400 K array-based comparative genomic hybridization (aCGH + SNP analysis was performed which identified a de novo suspected pathogenic deletion on chromosome 17q12 encompassing 28 genes. Despite the limited number of cases described in the literature with 17q12 rearrangements, our proband’s phenotypic features both overlap and expand on previously reported cases. Since syndrome-specific DNA sequencing studies failed to provide an explanation for this patient’s unusual habitus, we postulate that this case represents an expansion of the 17q12 microdeletion phenotype. Further analysis of the deleted interval is recommended for new genotype-phenotype correlations.

    In patients with meningococcal infection, devastating presentations, such as purpura fulminans, which can progress to extensive tissue necrosis of the limbs and digits, have a significant social impact. The case presented herein illustrates such a phenomenon in a patient who developed bilateral necrosis of the lower extremities as a result of infection with Neisseria meningitis. We emphasize that severe myalgia was the first clinical manifestation of meningococcal purpura fulminans in our case. However, myalgia has typically been overlooked and undervalued as an early clinical feature of meningococcal sepsis. Early recognition and prompt initial antibiotic therapy continue to be the cornerstones of the successful management of this dramatic disease, reducing morbidity and mortality.

    Full Text Available Traumatic subperiosteal hematoma (SpH usually presents late, after the initial trauma. It is generally seen in young males. Computed tomography is the best mode of imaging and helps to rule out orbital fracture or associated subdural hematoma. We present the clinical features and management of four patients seen at the orbit clinic with SpH. Management is based on time of presentation, visual acuity and any communicating bleed. The prognosis of traumatic SpH is excellent if treated with an individualized patient approach.

    Juvenile myelomonocytic leukemia (JMML) is a rare clonal myeloproliferative disorder of childhood. Major progress has been achieved in diagnosis and the understanding of the pathogenesis of JMML by identifying the genetic pathologies that occur in patients. Mutations of RAS, NF1, PTPN11, and CBL are found in approximately 80% of JMML patients. Distinct clinical features have been reported to be associated with specific gene mutations. The advent of genomic studies and recent identification of novel genetic mutations in JMML are important not only in diagnosis but also in the management and prognosis of the disease. Herein, we present 2 patients with JMML harboring different mutations, NRAS and c-CBL, respectively, with distinct clinical features and different therapeutic approaches.

    Full Text Available BACKGROUND: Scrub typhus is an infectious disease caused by Orientia tsutsugamushi. The differences in virulence of O. tsutsugamushi prototypes in humans are still unknown. We investigated whether there are any differences in the clinical features of the Boryoung and Karp genotypes. METHODOLOGY/PRINCIPAL FINDINGS: Patients infected with O. tsutsugamushi, as Boryoung and Karp clusters, who had visited 6 different hospitals in southwestern Korea were prospectively compared for clinical features, complications, laboratory parameters, and treatment responses. Infected patients in the Boryoung cluster had significantly more generalized weakness, eschars, skin rashes, conjunctival injection, high albumin levels, and greater ESR and fibrinogen levels compared to the Karp cluster. The treatment response to current antibiotics was significantly slower in the Karp cluster as compared to the Boryoung cluster. CONCLUSION: The frequency of occurrence of eschars and rashes may depend on the genotype of O. tsutsugamushi.

    Patients with Huntington's disease (HD) carrying CAG repeats beyond 60 are less frequently seen and clinical features of them have been rarely reported. We identified four unrelated patients carrying CAG repeats beyond 60 (84.0 ± 13.76, ranging from 74 to 104) from 119 Chinese HD patients via direct sequencing. These four were all early onset with a mean age at presenting symptom of 9.8 ± 1.71 years. Paternal transmission was found in three of them and the fourth was apparently sporadic. In addition, they had atypical onset symptoms including epilepsy, intellectual decline, tics and walking instability, which might lead the clinicians to make the wrong diagnosis in the early stage of disease. Our work explores clinical features of Chinese HD patients with an expanded CAG repeat over 60 and may help the clinicians make a correct diagnosis in the early stage of disease.

    We investigated the clinical features and gene mutation in a pedigree of spinocerebellar ataxia (SCA). A series of clinical tests was performed including visual examination, retinal angiography, visual evoked potential, electroretinogram and magnetic resonance imaging. Genomic DNA of the family members and normal controls was used for amplification of the (CAG)n repeats of SCA1, SCA2, SCA3, SCA6, SCA7, SCA17 and DRPLA genes by PCR. The number of (CAG)n was determined by 8% denaturing polyacrylamide gel electrophoresis and direct sequencing. The main features of 2 patients were ataxia, visual failure, retinal degeneration, cerebellar and pontine atrophy. A mutation in SCA7 gene was detected, while no mutations were found in SCA1, SCA2, SCA3, SCA6, SCA17 or DRPLA gene. Therefore, this is a pedigree of SCA7. Analysis of the CAG trinucleotide repeat expansion at the SCA7 locus can provide valuable insights into SCA7.

    2015-06-01

    The uniform multidrug therapy clinical trial, Brazil (U-MDT/CT-BR), database was used to describe and report the performance of available tools to classify 830 leprosy patients as paucibacillary (PB) and multibacillary (MB) at baseline. In a modified Ridley and Jopling (R&J) classification, considering clinical features, histopathological results of skin biopsies and the slit-skin smear bacterial load results were used as the gold standard method for classification. Anti-phenolic glycolipid-I (PGL-I) serology by ML Flow test, the slit skin smear bacterial load, and the number of skin lesions were evaluated. Considering the R&J classification system as gold standard, ML Flow tests correctly allocated 70% patients in the PB group and 87% in the MB group. The classification based on counting the number of skin lesions correctly allocated 46% PB patients and 99% MB leprosy cases. Slit skin smears properly classified 91% and 97% of PB and MB patients, respectively. Based on U-MDT/CT-BR results, classification of leprosy patients for treatment purposes is unnecessary because it does not impact clinical and laboratories outcomes. In this context, the identification of new biomarkers to detect patients at a higher risk to develop leprosy reactions or relapse remains an important research challenge.

    Full Text Available Background. We aimed to evaluate the efficacy of various diagnostic tools such as computerized tomography (CT, small bowel follow-through (SBFT, and capsule endoscopy (CE in diagnosing small bowel tumors (SBTs. Additionally, we aimed to evaluate the clinical features of SBTs missed by CE. Methods. We retrospectively studied 79 patients with histologically proven SBT. Clinical data were analyzed with particular attention to the efficacy of CT, SBFT, and CE in detecting SBT preoperatively. We also analyzed the clinical features of SBTs missed by CE. Results. The most common symptoms of SBT were bleeding (43% and abdominal pain (13.9%. Diagnostic yields were as follows: CT detected 55.8% of proven SBTs; SBFT, 46.1%; and CE, 83.3%. The sensitivity for detecting SBTs was 40.4% for CT, 43.9% for SBFT, and 79.6% for CE. Two patients with nondiagnostic but suspicious findings on CE and seven patients with negative findings on CE were eventually found to have SBT. These nine patients were eventually diagnosed with gastrointestinal stromal tumor (4, small polyps (3, inflammatory fibroid polyp (1, and adenocarcinoma (1. These tumors were located in the proximal jejunum (5, middle jejunum (1, distal jejunum (1, and proximal ileum (1. Conclusion. CE is more efficacious than CT or SBFT for detecting SBTs. However, significant tumors may go undetected with CE, particularly when located in the proximal jejunum.

    Hattori, Isao; Miyauchi, Toshiro

    2005-01-01

    In order to improve diagnosis of schizophrenia with onset in adolescents at an early stage, we investigated in detail the clinical features of 74 patients with schizophrenia, (23 males) at adolescents psychiatric clinic. Many of the subjects had been suffering from the illness about 14 years old but had not undergone their first psychiatric examination until a few years later. A high percentage (more than 80%) of our subjects presented psychiatric symptoms such as delusional remembrance, delusional moods, delusions of persecution and hypobulia. Additionally, more than 60% of our subjects presented auditory hallucinations. In general, teenage patients with schizophrenia onset show vague symptoms such as anxiety, embarrassment and strange moods rather than obvious hallucinations. Nevertheless, it was possible to identify certain clinical features of this disorder in adolescents: many patients suffer delusional remembrance, delusional moods and delusions of persecution immediately after the onset of the illness. Gradually, problematic behaviors such as anorexia, self injury, offences against their families, voluntary vomiting, etc., develop, but patients do not always receive psychiatric examination at this stage. After socially obvious problems such as school refusal, withdrawal from social activities and lowering of school record develop over a period of time, patients may be urged to undergo psychiatric examination. Our research again underlines the difficulty of achieving diagnosis of schizophrenia at an early stage. The key to early diagnosis appears to be the accurate identification of psychiatric symptoms in the early stages of the illness at school, or at home if possible, before socially problematic behaviors arise.

HGPS has an estimated incidence of one in four million to one in eight million births. The main clinical features of HGPS include short stature, craniofacial dimorphism, alopecia, bone fragility, and cardiovascular disorders. The most frequent cause of death is myocardial infarction at a mean age of 13 years old. Dental manifestations include delayed development and eruption of teeth, discoloration, crowding and rotation of teeth, and displaced teeth. Cone beam computed tomography images revealed the absence of the sphenoid, frontal, and maxillary sinus, flattening of the condyles and glenoid fossa, and bilateral hypoplasia of the mandibular condyles. The disease is caused by mutations in lamin A/C (LMNA). Here, we present a case report of an 11-year-old boy with classical features of HGPS, which was caused by a de novo germ-line mutation (C1824T, G608G) in exon 11 of the LMNA gene. Some uncommon HGPS-associated features in our patient, such as alterations in the facial sinuses and hypoplasia of the condyles, contributed to the expansion of the phenotypic spectrum of this syndrome from a dentomaxillofacial perspective.

    Fractures during clinical function have been reported as the major concern associated with all-ceramic dental restorations. The aim of this study was to analyze the fracture features of glass-ceramic and zirconia-based restorations fractured during clinical use. Twenty-seven crowns and onlays were supplied by dentists and dental technicians with information about type of cement and time in function, if available. Fourteen lithium disilicate glass-ceramic restorations and 13 zirconia-based restorations were retrieved and analyzed. Fractographic features were examined using optical microscopy to determine crack initiation and crack propagation of the restorations. The material comprised fractured restorations from one canine, 10 incisors, four premolars, and 11 molars. One crown was not categorized because of difficulty in orientation of the fragments. The results revealed that all core and veneer fractures initiated in the cervical margin and usually from the approximal area close to the most coronally placed curvature of the margin. Three cases of occlusal chipping were found. The margin of dental all-ceramic single-tooth restorations was the area of fracture origin. The fracture features were similar for zirconia, glass-ceramic, and alumina single-tooth restorations. Design features seem to be of great importance for fracture initiation.

    Full Text Available Objective Patients with drug-induced parkinsonism (DIP may have nigrostriatal dopaminergic degeneration. We studied the clinical features that may indicate nigrostriatal dopaminergic degeneration in patients with DIP. Methods Forty-one DIP patients were classified into normal and abnormal [18F] FP-CIT scan groups. Differences in 32 clinical features and drug withdrawal effects were studied. Results Twenty-eight patients had normal (Group I and 13 patients had abnormal (Group II scans. Eight patients of Group I, but none of Group II, had taken calcium channel blockers (p = 0.040. Three patients of Group I and six of Group II had hyposmia (p = 0.018. After drug withdrawal, Group I showed greater improvement in Unified Parkinson’s Disease Rating Scale total motor scores and subscores for bradykinesia and tremors than Group II. Only hyposmia was an independent factor associated with abnormal scans, but it had suboptimal sensitivity. Conclusion None of the clinical features were practical indicators of nigrostriatal dopaminergic degeneration in patients with DIP.

    Objective. To describe the clinical, radiological and MRI features of six atypical cases of histologically proven appendicular Ewing sarcoma/ primitive neuroectodermal tumour (PNET). Design. Retrospective review of case notes and available imaging was carried out. Patients. Six patients (4 male, 2 female; mean age 27 years, range 19-44 years), presenting over a 77-month period, were identified from the Bone Tumour Register. All had unusual clinical and imaging features for Ewing sarcoma/PNET.Results and conclusions. Four tumours were centred on the distal femoral metaphysis, one in the proximal tibial metaphysis and one in the distal tibial metaphysis. Plain radiographs were available in four cases and showed minor cortical changes. MRI demonstrated a relatively small, eccentrically located intraosseous component with a large, eccentric extraosseous component. Extension into the epiphysis was seen in three cases and into the adjacent joint in two cases. Intraosseous ''skip'' metastases were present in three cases. The clinical and imaging features were atypical for conventional intraosseous Ewing sarcoma/PNET and the exact site of origin (intraosseous, periosteal or soft-tissue) was unclear. (orig.)

    Solitary rectal ulcer syndrome (SRUS) is an uncommon benign disease, characterized by a combination of symptoms, clinical findings and histological abnormalities. Ulcers are only found in 40% of the patients; 20% of the patients have a solitary ulcer, and the rest of the lesions vary in shape and size, from hyperemic mucosa to broad-based polypoid. Men and women are affected equally, with a small predominance in women. SRUS has also been described in children and in the geriatric population. Clinical features include rectal bleeding, copious mucus discharge, prolonged excessive straining, perineal and abdominal pain, feeling of incomplete defecation, constipation, and rarely, rectal prolapse. This disease has well-described histopathological features such as obliteration of the lamina propria by fibrosis and smooth muscle fibers extending from a thickened muscularis mucosa to the lumen. Diffuse collage deposition in the lamina propria and abnormal smooth muscle fiber extensions are sensitive markers for differentiating SRUS from other conditions. However, the etiology remains obscure, and the condition is frequently associated with pelvic floor disorders. SRUS is difficult to treat, and various treatment strategies have been advocated, ranging from conservative management to a variety of surgical procedures. The aim of the present review is to summarize the clinical features, pathophysiology, diagnostic methods and treatment strategies associated with SRUS.

    Introduction To improve our understanding of sex differences in the clinical characteristics of Parkinson’s Disease, we sought to examine differences in the clinical features and disease severity of men and women with early treated Parkinson’s Disease (PD) enrolled in a large-scale clinical trial. Methods Analysis was performed of baseline data from the National Institutes of Health Exploratory Trials in Parkinson’s Disease (NET-PD) Long-term Study-1, a randomized, multi-center, double-blind, placebo-controlled study of 10 grams of oral creatine/day in individuals with early, treated PD. We compared mean age at symptom onset, age at PD diagnosis, and age at randomization between men and women using t-test statistics. Sex differences in clinical features were evaluated, including: symptoms at diagnosis (motor) and symptoms at randomization (motor, non-motor, and daily functioning). Results 1,741 participants were enrolled (62.5% male). No differences were detected in mean age at PD onset, age at PD diagnosis, age at randomization, motor symptoms, or daily functioning between men and women. Differences in non-motor symptoms were observed, with women demonstrating better performance compared to men on SCOPA-COG (Z = 5.064, p<0.0001) and Symbol Digit Modality measures (Z = 5.221, p<0.0001). Conclusions Overall, men and women did not demonstrate differences in clinical motor features early in the course of PD. However, the differences observed in non-motor cognitive symptoms suggests further assessment of the influence of sex on non-motor symptoms in later stages of PD is warranted. PMID:26171861

    Full Text Available Objective To investigate the onset pattern, clinical manifestations, laboratory findings and imaging features of 17 Chinese patients with steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT. Methods The clinical data of 17 SREAT patients were collected. Retrospective analysis of their clinical features, as well as their serum levels of anti-thyroid, cerebrospinal fluid (CSF biochemical indicators, MRI and therapy was performed. Results The initial symptoms of those patients were seizures (4 cases, psychiatric symptoms (4 cases, hypomnesis (4 cases, walking unsteadiness (2 cases, headache (2 cases and dysarthria (1 case. Three cases were acute onset, 5 cases subacute onset and 9 cases chronic onset. The anti-thyroid peroxidase antibody (anti-TPO of 17 cases were significantly increased, average (928.63 ± 406.28 × 10 3 IU/L. The anti?thyroglobulin antibody (anti-TG of 15 cases was increased, average (601.27 ± 1014.12 × 10 3 IU/L. The protein in CSF was mildly increased, average (513.75 ± 283.15 mg/L. The EEG of 5 patients presented slow wave and the EEG of 2 patients showed epileptiform discharge. The brain MRI of 11 patients showed multifocal lesions in frontal lobe, temporal lobe, parietal lobe, basal ganglia, centrum ovale, corpus callosum, thalamus, cerebellum, and brain stem. The findings of clinical immunological index and tumor markers were normal. Besides, the prognosis of 11 patients treated with methylprednisolone and 3 patients treated with dexamethasone were good. Recurrence occurred in 2 patients. Conclusion Basically, the clinical features of Chinese SREAT patients present seizures, hypomnesis and psychiatric symptoms associated with increased anti-thyroid and multifocal lesions in gray and white matter of brain.

    Full Text Available In Brazil, current trends of the AIDS epidemic include an increase in transmission through heterosexual contact, predominantly from men to women, with more cases of AIDS in women and more children contaminated by vertical transmission. There is also a high proportion of cases in poor people or people living in small towns. HIV-infected patients with high levels of immunodeficiency are frequently hospitalized after their first visit to the clinic due to opportunistic infections, characteristic of advanced disease. This study characterized the clinical and laboratory pattern of AIDS in a sample of patients attended for the first time in the AIDS clinic of the Federal University of Bahia Hospital (HUPES in Salvador, Brazil. We revised medical charts of cases of subjects registered at the outpatient AIDS clinic from January 1997 to December 2003. The demographics, clinical data, and laboratory characteristics were analyzed to determine the degree of immunodeficiency at the time of admission. A total of 377 patients were evaluated (58.6% were male, with a mean sample age of 33.4 years. The most frequent clinical manifestations were asthenia, weight loss, fever, anemia, dermatitis, oral thrush and diarrhea. CDC criteria were not adequate to define the initial cases. After admission to the outpatient clinic, nearly 25% of the patients were hospitalized immediately, indicating delay in the diagnosis. In Bahia, the initial presentation of HIV-infected patients to health care assistance is occurring at a late stage of the disease, when signs and symptoms of immunodeficiency are already established. Efforts are necessary to construct strategies to make an early diagnosis of these patients, improve the quality of care, and guarantee the benefits of antiretroviral therapy, when it is indicated.

    Vibrio parahaemolyticus is a bacterial pathogen that can cause illness after the consumption or handling of contaminated seafood. The primary virulence factors associated with V. parahaemolyticus illness are thermostable direct hemolysin (TDH) and Tdh-related hemolysin (TRH). However, clinical strains lacking tdh and trh have recently been isolated, and these clinical isolates are poorly understood. To help understand the emergence of clinical tdh- and trh-negative isolates, a genomic approach was used to comprehensively compare 4 clinical tdh- and trh-negative isolates with 16 environmental tdh- and trh-negative isolates and 34 clinical isolates positive for tdh or trh, or both, with the objective of identifying genomic features that are unique to clinical tdh- and trh-negative isolates. The prevalence of pathogenicity islands (PAIs) common to clinical isolates was thoroughly examined in each of the clinical tdh- and trh-negative isolates. The tdh PAI was not present in any clinical or environmental tdh- and trh-negative isolates. The trh PAI was not present in any environmental isolates; however, in clinical tdh- and trh-negative isolate 10-4238, the majority of the trh PAI including a partial trh1 gene was present, which resulted in reclassification of this isolate as a tdh-negative and trh-positive isolate. In the other clinical tdh- and trh-negative isolates, neither the trh gene nor the trh PAI was present. We identified 862 genes in clinical tdh- and trh-negative isolates but not in environmental tdh- and trh-negative isolates. Many of these genes are highly homologous to genes found in common enteric bacteria and included genes encoding a number of chemotaxis proteins and a novel putative type VI secretion system (T6SS) effector and immunity protein (T6SS1). The availability of genome sequences from clinical V. parahaemolyticus tdh- and trh-negative isolates and the comparative analysis may help provide an understanding of how this pathotype is able to

    Our objective was to identify the main clinical and epidemiological features of ALS in a large cohort of African American (AA) patients and compare them to Caucasian (CA) patients in a clinic-based population. We retrospectively identified 207 patients who were diagnosed with ALS based on the revised El Escorial criteria (60 AA and 147 CA subjects). Patients were seen in the Neuromuscular Division at the University Medical Center. We compared epidemiological and clinical features of these two groups, focusing on age of onset and diagnosis, clinical presentation and survival. Results showed that AA patients had a significantly younger age of disease onset (55 years vs. 61 years for CA, p = 0.011) and were diagnosed at an earlier age (56 years vs. 62 years, p = 0.012). In younger ALS patients (population and males in the CA population (p = 0.025). In a multivariable Cox proportional hazard model, survival rates were not different between the groups. In both groups, survival significantly increased with younger age. In conclusion, AA patients presented at an earlier age, but there was no difference in survival compared to CA patients. A gender reversal occurred in younger ALS patients, with AA patients more likely to be female and CA patients more likely to be male.

    SUMMARY Contemporary clinical assessment of back pain is based on the diagnostic triage paradigm. The most common diagnostic classification is nonspecific back pain, considered to be of nociceptive etiology. A small proportion are diagnosed with radicular pain, of neuropathic origin. In this study we review the body of literature on the prevalence of neuropathic features of back pain, revealing that the point prevalence is 17% in primary care, 34% in mixed clinical settings and 53% in tertiary care. There is evidence that neuropathic features of back pain are not restricted to typical clinical radicular pain phenotypes and may be under-recognized, particularly in primary care. The consequence of this is that in the clinic, diagnostic triage may erroneously classify patients with nonspecific back pain or radicular pain. A promising alternative is the development of mechanism-based pain phenotyping in patients with back pain. Timely identification of contributory pain mechanisms may enable greater opportunity to select appropriate therapeutic targets and improve patient outcomes.

    Critical appraisal of the literature highlights that the discriminative power of gait-related features in patients with hip osteoarthritis (OA) has not been fully explored. We aimed to reduce the number of gait-related features and define the most discriminative ones comparing the three-dimensional gait analysis of 20 patients with hip osteoarthritis (OA) with those of 17 healthy peers. First, principal component analysis was used to reduce the high-dimensional gait data into a reduced set of interpretable variables for further analysis, including tests for group differences. These differences were indicative for the selection of the top 10 variables to be included into linear discriminant analysis models (LDA). Our findings demonstrated the successful data reduction of hip osteoarthritic-related gait features with a high discriminatory power. The combination of the top variables into LDA models clearly separated groups, with a maximum misclassification error rate of 19%, estimated by cross-validation. Decreased hip/knee extension, hip flexion and internal rotation moment were gait features with the highest discriminatory power. This study listed the most clinically relevant gait features characteristics of hip OA. Moreover, it will help clinicians and physiotherapists understand the movement pathomechanics related to hip OA useful in the management and design of rehabilitation intervention.

    Full Text Available Lichen planus pemphigoides (LPP is a rare, acquired and autoimmune disorder. LPP clinically, histologically and immunologically appears to be a combination of lichen planus and bullous pemphigoides. LPP is usually idiopathic but some cases have been associated with drugs, phototherapy, infections and malignancy. It has different clinical variants such as presenting with only oral lesions; with oral and cutaneous lesions and with only cutaneous lesions, respectively. We present two cases with typical histologic and immunofluorescence features of LPP. Our 55 years old male case had typical lichen planus lesions with widespread bulla and erosions; he responded systemic steroid treatment in a short time. Bulla and erosions were not prominent in our 16 years old female case and with topical treatments to her lesions improved in a short time. LPP should be considered in the clinical differential diagnosis of vesiculoerosive oral mucosal and cutaneous diseases.

    X-linked agammaglobulinemia (XLA) is caused by BTK mutations, patients typically show <2% of peripheral B cells and reduced levels of all immunoglobulins; they suffer from recurrent infections of bacterial origin; however, viral infections, autoimmune-like diseases, and an increased risk of developing gastric cancer are also reported. In this work, we report the BTK mutations and clinical features of 12 patients diagnosed with XLA. Furthermore, a clinical revision is also presented for an additional cohort of previously reported patients with XLA. Four novel mutations were identified, one of these located in the previously reported mutation refractory SH3 domain. Clinical data support previous reports accounting for frequent respiratory, gastrointestinal tract infections and other symptoms such as the occurrence of reactive arthritis in 19.2% of the patients. An equal proportion of patients developed septic arthritis; missense mutations and mutations in SH1, SH2 and PH domains predominated in patients who developed arthritis.

    Mycosis fungoides (MF) simulates a variety of dermatologic disorders histopathologically and clinically, well deserving the designation of a great mimicker. Interstitial MF is a rare, but well-recognized histopathological variant resembling the interstitial form of granuloma annulare or the inflammatory phase of morphea. From a clinical standpoint, MF can have a wide array of manifestations, including an anecdotal presentation with lesions clinically suggestive of lichen sclerosus (LS). We herein report a 25-year-old man with a history of patch-stage MF who later developed widespread LS-like lesions histopathologically consistent with interstitial MF. In some biopsies, additional features resembling LS were discerned. We think that our case might represent a unique variant of interstitial MF presenting with LS-like lesions. The diagnostic challenge arising from this uncommon presentation is discussed together with review of the literature.

    Full Text Available The author studied in detail the specific features of the clinical manifestations reflecting a granulomatous inflammatory response and necrotizing polyangiitis, by using her experience in following up 70 patients with granulomatosis and polyangiitis (Wegener's, and analyzed their early symptoms, premorbid background, and possible predictors. Granulomatous inflammation and its related clinical manifestations (primarily orbital pseudotumor and subfold granuloma of the larynx was demonstrated to tend over time to occupy a dominant place in the clinical picture of the disease while the proportion of the symptoms apparently related to necrotizing vasculitis was generally decreased. Interpretation of mechanisms for the development of granulomatosis with polyangiitis (Wegener's may be of value for the further elaboration of an optimal treatment strategy.

    BACKGROUND: Diagnosing pericardial effusion is critical for optimal patient care. Typically, clinicians use physical examination findings and historical features suggesting pericardial effusion to determine which patients require echocardiography. The diagnostic characteristics of these tools are not well described. The objective of this study is to determine the prevalence of historical features and sensitivity of clinical signs to inform clinicians when to proceed with echocardiogram. METHODS: A retrospective review of point-of-care echocardiograms performed over a two and a half year period in two emergency departments were reviewed for the presence of a pericardial effusion. Patient charts were reviewed and abstracted for presenting symptoms, historical features and clinical findings. The prevalence of presenting symptoms and historical features and the sensitivity of classic physical examination findings associated with pericardial effusion and tamponade were determined. RESULTS: One hundred and fifty-three patients with pericardial effusion were identified. Of these patients, the most common presenting complaint was chest pain and shortness of breath. Patients had no historical features that would suggest pericardial effusion in 37.5% of cases. None of the patients with pericardial effusion or pericardial tamponade had all of the elements of Beck’s triad. The sensitivity of Beck’s triad was found to be 0 (0%–19.4%). The sensitivity for one finding of Beck’s triad to diagnose pericardial tamponade was 50% (28.0%–72.0%). CONCLUSION: History and physical examination findings perform poorly as tests for the diagnosis of pericardial effusion or pericardial tamponade. Clinicians must liberally evaluate patients suspected of having a pericardial effusion with echocardiography. PMID:28123617

    Background: Skin infections caused by coryneform bacteria are common dermatological conditions. However, to the best of our knowledge, no studies are available on the clinical characteristics and epidemiological features of this group of disorders as one entity from India and abroad. Aims: To study the clinical and epidemiological features of coryneform skin infections Methods: A total of 75 patients presenting with clinically distinctive lesions of pitted keratolysis, erythrasma and trichobacteriosis to our hospital were included in the study. Cases were interviewed with particular emphasis on epidemiological features and the various clinical findings were recorded. Investigations like Gram's stain, Wood's light examination, 10% KOH scrapings, were done in selected cases to ascertain the diagnosis. Results: Pitted keratolysis was more common in the age group of 31-40 years (40%) with a male preponderance (76.7%), most commonly affecting pressure bearing areas of the soles with malodour (86.7%) and frequent contact with water (58.3%) constituting the most important presenting symptom and provocating factor respectively. Erythrasma affected both male and female patients equally and was more commonly detected in patients with a BMI > 23kg/m2 (62.5%) and in diabetics (50%). All patients with trichobacteriosis presented with yellow coloured concretions in the axillae. Bromhidrosis (71.4%) and failure to regularly use an axillary deodorant (71.4%) were the most common presenting symptom and predisposing factor respectively. Conclusion: Coryneform skin infections are common dermatological conditions, though epidemiological data are fragmentary. Hyperhidrosis is a common predisposing factor to all three coryneform skin infections. Asymmetrical distribution of pits has been reported in our study. Diabetic status needs to be evaluated in all patients with erythrasma. Woods lamp examination forms an indispensible tool to diagnose erythrasma and trichobacteriosis. PMID

    Full Text Available Peroxisomal disorders are a group of genetically heterogeneous metabolic diseases related to dysfunction of peroxisomes. Dysmorphic features, neurological abnormalities, and hepatic dysfunction can be presenting signs of peroxisomal disorders. Here we presented dysmorphic facial features and other clinical characteristics in two patients with PEX1 gene mutation. Follow-up periods were 3.5 years and 1 year in the patients. Case I was one-year-old girl that presented with neurodevelopmental delay, hepatomegaly, bilateral hearing loss, and visual problems. Ophthalmologic examination suggested septooptic dysplasia. Cranial magnetic resonance imaging (MRI showed nonspecific gliosis at subcortical and periventricular deep white matter. Case II was 2.5-year-old girl referred for investigation of global developmental delay and elevated liver enzymes. Ophthalmologic examination findings were consistent with bilateral nystagmus and retinitis pigmentosa. Cranial MRI was normal. Dysmorphic facial features including broad nasal root, low set ears, downward slanting eyes, downward slanting eyebrows, and epichantal folds were common findings in two patients. Molecular genetic analysis indicated homozygous novel IVS1-2A>G mutation in Case I and homozygous p.G843D (c.2528G>A mutation in Case II in the PEX1 gene. Clinical findings and developmental prognosis vary in PEX1 gene mutation. Kabuki-like phenotype associated with liver pathology may indicate Zellweger spectrum disorders (ZSD.

    Full Text Available Objectives:  To study the clinical features and diagnostic value of CT in Fahr’s disease. Methods:  We retrospectively analyzed skull images of 8,000 cases and observed the incidence and imaging characteristics of Fahr’s disease. Results: Fahr’s disease were found in 6 patients (6/4000=0.075%whose ages ranged from 16 to 62 years (average age:38.5±6.4years. We found that 6 Fahr’s disease had been incidentally detected in 4 men(4/6=66.7% and 2 women(2/6=33.4%; serum calcium:2.13~2.42 mmol/L,serum phosphor:1.0~1.6 mmol/L.The most common CT feature of Fahr’s disease is the presence of small bilateral intracranial calcifications which are usually restricted to the bilateral globus pallidus, putamen, caudate nucleus, thalamus, dentate nucleus and white matter of the cerebral hemispheres. Conclusions: Combined with clinical manifestations and imaging features, we can make a clear diagnosis of the Fahr’s disease.

    Full Text Available BACKGROUND: Severe malaria (SM is a major cause of death in sub-Saharan Africa. Identification of both specific and sensitive clinical features to predict death is needed to improve clinical management. METHODS: A 13-year observational study was conducted from 1997 through 2009 of 2,901 children with SM enrolled at the Royal Victoria Teaching Hospital in The Gambia to identify sensitive and specific predictors of poor outcome in Gambian children with severe malaria between the ages 4 months to 14 years. We have measured the sensitivity and specificity of clinical features that predict death or development of neurological sequelae. FINDINGS: Impaired consciousness (odds ratio {OR} 4.4 [95% confidence interval {CI}, 2.7-7.3], respiratory distress (OR 2.4 [95%CI, 1.7-3.2], hypoglycemia (OR 1.7 [95%CI, 1.2-2.3], jaundice (OR 1.9 [95%CI, 1.2-2.9] and renal failure (OR 11.1 [95%CI, 3.3-36.5] were independently associated with death in children with SM. The clinical features that showed the highest sensitivity and specificity to predict death were respiratory distress (area under the curve 0.63 [95%CI, 0.60-0.65] and impaired consciousness (AUC 0.61[95%CI, 0.59-0.63], which were comparable to the ability of hyperlactatemia (blood lactate>5 mM to predict death (AUC 0.64 [95%CI, 0.55-0.72]. A Blantyre coma score (BCS of 2 or less had a sensitivity of 74% and specificity of 67% to predict death (AUC 0.70 [95% C.I. 0.68-0.72], and sensitivity and specificity of 74% and 69%, respectively to predict development of neurological sequelae (AUC 0.72 [95% CI, 0.67-0.76].The specificity of this BCS threshold to identify children at risk of dying improved in children less than 3 years of age (AUC 0.74, [95% C.I 0.71-0.76]. CONCLUSION: The BCS is a quantitative predictor of death. A BCS of 2 or less is the most sensitive and specific clinical feature to predict death or development of neurological sequelae in children with SM.

    Objective: To test the hypothesis that core and suggestive features in possible dementia with Lewy bodies (DLB) would vary in their ability to predict an abnormal dopamine transporter scan and therefore a follow-up diagnosis of probable DLB. A further objective was to assess the evolution of core and suggestive features in patients with possible DLB over time depending on the 123I-FP-CIT SPECT scan result. Methods: A total of 187 patients with possible DLB (dementia plus one core or one suggestive feature) were randomized to have dopamine transporter imaging or to follow-up without scan. DLB features were compared at baseline and at 6-month follow-up according to imaging results and follow-up diagnosis. Results: For the whole cohort, the baseline frequency of parkinsonism was 30%, fluctuations 29%, visual hallucinations 24%, and REM sleep behavior disorder 17%. Clinician-rated presence of parkinsonism at baseline was significantly (p = 0.001) more frequent and Unified Parkinson’s Disease Rating Scale (UPDRS) score at baseline was significantly higher (p = 0.02) in patients with abnormal imaging. There was a significant increase in UPDRS score in the abnormal scan group over time (p < 0.01). There was relatively little evolution of the rest of the DLB features regardless of the imaging result. Conclusions: In patients with possible DLB, apart from UPDRS score, there was no difference in the evolution of DLB clinical features over 6 months between cases with normal and abnormal imaging. Only parkinsonism and dopamine transporter imaging helped to differentiate DLB from non-DLB dementia. PMID:27511183

    Full Text Available This study was designed to analyse the clinical and epidemiological data from human parvovirus B19 cases in a six-year study of rash diseases conduct in an urban area in Brazil (Niterói city area, State of Rio de Janeiro. A total of 673 patients with acute rash diseases were seen at two primary health care units and at a general hospital. A clotted blood sample was collected from all subjects at the time of consultation. Forty-nine per cent (330 cases of the patients were negative for dengue, rubella and measles IgM or for low avidity IgG to HHV-6. Of these 330, 105 (31.8% were identified as IgM positive to parvovirus B19 by using an antibody capture EIA. During the study period, three distinct peaks of parvovirus infection were detected, suggesting that the disease appears to cycle in approximately 4-5 years. B19 infection was characterized by variable combinations of fever, flu-like symptoms, arthropathy, and gastrointestinal symptoms. Frequency of fever and arthropathy was substantially higher in adults, 75% [chi2 (1 D.F. = 11.39, p = 0.0007] and 62.5% [chi2 (1 D.F. = 29.89, p = 0.0000], respectively. "Slapped-cheek" appearance and reticular or lace-like rash were seen in only 30.1% of the children. No adult presented this typical rash. The lack of the typical rash pattern in a large proportion of parvovirus B19 and the similarity of clinical manifestations to other rash diseases, specially to rubella, highlight the difficulty of diagnosing B19 infection on clinical grounds alone.

    The erysipeloid form of cutaneous leishmaniasis is considered as an unusual and rare clinical presentation in Tunisia. Our prospective study on 4 observations, aimed at examining the clinical, histological and progressive features of the "erysipeloid" form of cutaneous leishmaniasis. Our patients were 3 females and one male more than 62 years old. Their cutaneous leishmaniasis was clinically characterised by an infiltrated and extensive plaque which was localised on the face covering the nose and cheeks looking like erysipelas. The treatment was intramuscular meglumine antimoniate (Glucantime) in three cases and metronidazole in one case. A regression without scar was noticed in all the cases. On the histological examination, we observed an intense epidermic and constant hyperplasia with presence of amastigotes in 3 cases. Our study shows the lesional polymorphism of the old word cutaneous leishmaniasis in our region. The "erysipeloid" form of cutaneous leishmaniasis is a rare clinical presentation which generally affects women. If the clinical aspect is very meaningful, the histological aspect is meaningful but not specific.

    The family of an "affected" subject with limb girdle dystrophy has been studied in order to assess the clinical-hereditary characteristics of the disease and to contribute to its definite genetic features (phenotypical expressiveness of the pathologic gene). The diagnosis of certitude was based on the anamnestic-clinical criteria and instrumental investigations, supported by histological and histochemical studies of the muscles. The clinical, electromyographic and biochemical data made it possible to distinguish the "affected" from the "subclinical" and the healthy subjects. The subjects that, without noticeable symptoms of neuromuscular disorders, showed a slight clinical expressiveness which didn't alter the normal social and working activities, have been defined "subclinical". The modalities of hereditary transmission of this form of muscular dystrophy are considered in the light of the genetics most present trends that are tending to overcome the dominant-recessive dualism. The possibility of a modality of transmission definable as "intermediate inheritance" is proposed. In the case of the examined family the hypothesis that a pathologic recessive autosomic gene gives rise to a clinical expressiveness in heterozygote subjects seems tenable. This situation definable as "incomplete recessive" is rarely found in the limb girdle dystrophy.

    Anti-N-methyl D-aspartate (NMDA) receptor encephalitis is the most common type of encephalitis in the spectrum of autoimmune encephalitis defined by antibodies targeting neuronal surface antigens. In the present study, the clinical spectrum of this disease is presented using instructive cases in correlation with the anti-NMDA receptor antibody titers in the cerebrospinal fluid (CSF) and serum. A total of 7 female patients admitted to the hospital of Hannover Medical School (Hannover, Germany) between 2008 and 2014 were diagnosed with anti-NMDA receptor encephalitis. Among these patients, 3 cases were selected to illustrate the range of similar and distinct clinical features across the spectrum of the disease and to compare anti-NMDA antibody levels throughout the disease course. All patients received immunosuppressive treatment with methylprednisolone, intravenous immunoglobulin and/or plasmapheresis, followed in the majority of patients by second-line therapy with rituximab and cyclophosphamide. The disease course correlated with NMDA receptor antibody titers, and to a greater extent with the ratio between antibody titer and protein concentration. A favorable clinical outcome with a modified Rankin Scale (mRS) score of ≤1 was achieved in 4 patients, 1 patient had an mRS score of 2 after 3 months of observation only, whereas 2 patients remained severely impaired (mRS score 4). Early and aggressive immunosuppressive treatment appears to support a good clinical outcome; however, the clinical signs and symptoms differ distinctively and treatment decisions have to be made on an individual basis.

    Full Text Available Aim: the aim of the study is to evaluate the socio-demographic and clinical features with prognostic value in predicting evolution in severe OCD.Materials and methods: patients with a main diagnosis of OCD were recruited according to DSM-IV criteria. Socio-demographic and clinical features were assessed by mean of a semi-structured interview and clinical rating scales (Y-BOCS, HAM-A, HAM-D and SCID-II. Two subgroups were compared according to the severity of symptoms (severe vs mild-moderate.Results: the total sample was made up of 450 OCD subjects aged 34.5±12.1, with a mean age of onset 22.3±9.1; 215 subjects (47.8% were females. Patients with severe OCD (Y-BOCS ≥ 32 showed a more insidious onset and a more chronic course compared to patients with mild-moderate symptoms. Other predictors of increased OCD severity were washing and hoarding compulsions. Lastly, the severity of the obsessive-compulsive condition was higher when it was associated either with mood disorders or with Axis II disorders (particularly Cluster A.Discussion: our study shows a correlation between severe OCD and severity predictors such as functional impairment and mood disorders. Furthermore washing and hoarding symptoms, lifetime comorbity with mood disorders and Cluster A personality disorders seem to predict OCD severity.

    Full Text Available Different proposed pathophysiological mechanisms can result in variable clinical presentations of cervical radiculopathy (CR, often making it difficult to detect minor nerve root (NR conditions. This descriptive study determined (1 the level(s of  NR involvement suggested by the distribution patterns of clinical features and detected by magnetic resonance imaging (MRI and (2 the most common associations between the different variables in patients diagnosed with acute CR by a neurosurgeon. A physiotherapist blinded to the level(s of NR involvement performed a standardized interview on 21 subjects to determine the distribution patterns of pain and paraesthesia, and a neurological examination. The Fisher exact test was used to determine associations between the different variables. Only seven subjects presented clinically and radiologically with the same single-level NR involvement. Multiple- level presentations occurred which might be due to dermatomal overlapping, central sensitization or the possible involvement of two adjacent NR levels. Distribution patterns of motor weakness, pain and paraesthesia, and to a lesser extent sensory and reflex changes, have value in identifying the compressed NR level. For this sample the distri-bution patterns of radicular features identified C6 and C8 with more certainty than C7.

    Objective To investigate clinical features and anesthetic management of multiple endocrine neoplasia (MEN) associated with pheochromocytoma.Methods Medical records of patients who were diagnosed as multiple endocrine neoplasia a ssociated with pheochromocytoma in our hospital from April 1977 to April 2001 were reviewed retrospectively. The demographic data, clinical presentations, fami ly history, biochemical examinations, type of MEN, sequence of different surgica l procedures, anesthetic methods and hemodynamics during surgery were analyzed. Results Thirteen cases of MEN associated with pheochromocytoma were investigated, accounting for 6% (13/213) of the pheochromocytoma patients admitted into our hospital. Nine of the 13 patients presented as type Ⅱa MEN (Sipple syndrome), on e as type Ⅱb MEN, and three as mixed MEN. Four patients with typeⅡa MEN had a family history of similar disease. Five patients with other coexisting endocri ne disorders first underwent excision of the pheochromocytomas, although only tw o had hypertensive symptoms at the time of admittance. Seven patients without h istories of hypertension received surgical treatment for pheochromocytoma second ly. The excision of pheochromocytoma was performed under general anesthesia in 8 patients and epidural block in 4 patients. Marked hemodynamic fluctuation was recorded in 8 patients. No perioperative death was recorded. Conclusion Pheochromocytoma may be linked to other endocrine disorders during MEN, either as the main clinical presentation or most frequently as an occult tumor. Recognition of this feature of pheochromocytoma is of importance to the improvement of diagnosis and treatment both for pheochromocytoma and MEN.

    The objective of this study was to investigate the immunophenotypic subtype profiles of 207 pediatric patients with acute lymphoblastic leukemia (ALL) and its correlation with cytogenetics and clinical features. 207 children with ALL were immunophenotyped by four color flow cytometry using a panel of monoclonal antibodies. 207 patients were enrolled in this study, out of which 146 cases were subjected to karyotype analysis by R-banding technology. The results showed that 11.6% out of 207 children with ALL were identified as T-ALL, 88.4% as B-ALL. Myeloid antigen (MyAg) expression was documented in 42.5% out of 207 cases analyzed and CD13 was the most commonly expressed MyAg (31.4%). No difference was observed in the expression of MyAg between the groups of patients with T-ALL (41.7%) and B-ALL (42.6%). Abnormal karyotypes were detected in 84 out of 146 (57.5%) children. The clinical and biological characteristics of ALL patients between MyAg(+) and MyAg(-) groups showed that higher percentage of patients with high WBC count (> 50 × 10(9)/L) and higher CD34 positivity were found to be correlated with MyAg(+) ALL. It is concluded that immunophenotype analysis is useful for ALL diagnosis and classification, and the immunophenotypes are in relevance to the abnormal cytogenetic changes as well as clinical features in childhood ALL.

    Objective: To analyze the clinical features of lung cancer diagnosed by bronchoscopy. Methods:The clinical features of2168 patients with lung cancer diagnosed by bronchoscopy were retrospectively analyzed, including gender, age, pathological type, diseased region, manifestations under bronchoscopy and methods of drawing materials. Results:The ratio of male/female was 4.8:1 and the peak onset age was 60~69 years old. The major pathological type was squamous cell carcinoma (44.5%), then adenocarcinoma (25.9%) and small cell lung cancer (18.3%). The incidence of squamous cell carcinoma was the highest in males (50.6%), while that of adenocarcinoma in females (56.2%). The positive diagnostic rates of forceps biopsy, brush biopsy, bronchial alveolar lavage and transbronchial needle aspiration were 81.6%, 49.4%, 18.2% and 62.6%, respectively, whereas that of biopsy combined with brush biopsy came up to 89.0%. Conclusion: Bronchoscopy is an important method in diagnosis of lung cancer. Different ages and genders of patients with lung cancer have different onset, and the distribution of pathological types is diverse. Attaching more importance to bronchoscopy and improving biopsy technique can signiifcantly improve the diagnostic rate and provide reliable evidences for clinical treatment.

    Full Text Available Background. Anti-neuronal autoimmunity may cause cognitive impairment that meets the criteria for dementia. Objective. Our aim was to detect the incidence and clinical features of autoimmune encephalitis imitating clinical findings of primary dementia disorders and to delineate the validity of anti-neuronal antibody screening in dementia patients. Methods. Fifty consecutive patients fulfilling the clinical criteria for primary dementia, 130 control patients, and 50 healthy controls were included. Their sera were investigated for several ion channel and glutamic acid decarboxylase (GAD antibodies by a cell-based assay, radioimmunoassay, and ELISA, as required. Results. Sixteen patients satisfying dementia criteria had atypical findings or findings suggestive of autoimmune encephalitis. N-methyl-D-aspartate receptor (NMDAR antibody was detected in a patient with dementia, Parkinsonism, and REM sleep behavior disorder (RBD fulfilling the criteria for dementia with Lewy bodies (DLB. One control patient with bipolar disease displayed low anti-GAD antibody levels. Conclusions. Our study showed for the first time the presence of parkinsonism and RBD in an anti-NMDAR encephalitis patient mimicking DLB. Although autoimmune encephalitis patients may occasionally present with cognitive decline, most dementia patients do not exhibit anti-neuronal antibodies, suggesting that routine analysis of these antibodies in dementia is not mandatory, even though they display atypical features.

    Extraintestinal manifestations (EIMs) cause increased morbidity and decreased quality of life in Crohn disease (CD). Ankylosing spondylitis (AS) belongs to EIMs. Very little is known on the clinical features of CD concomitant with AS. This study is to investigate the clinical features of CD patients with AS.We retrospectively collected all CD patients with AS in our hospital, and established a comparison group (CD without AS) with age, sex, and duration of Crohn disease matched. Clinical information was retrieved for comparison.Eight CD + AS patients were identified from 195 CD patients. Sixteen CD patients were randomly selected into comparison group. All CD + AS patients were male, HLA-B27 (+), and rheumatoid factor (-) with an average age of 40.8 ± 4.52 years. Significant correlation between disease activity of CD and AS was revealed (r = 0.857, P = 0.011). Significant correlation between disease activity of CD and functional limitation associated with AS was identified (r = 0.881, P Crohn disease activity index (CDAI), Bath AS disease activity index, and Bath AS functional index(BASFI) scores (r = 0.73-0.93, P Disease activity of CD correlates with disease activity of AS and functional limitation caused by AS. CRP, ESR, and Alb/Glo may serve as biomarkers for disease activity and functional limitation in CD patients concomitant with AS, although future studies are expected.

    Full Text Available OBJECTIVE: The purpose of this study was to analyze the clinical features and prognostic factors of surgical outcome of foot drop caused by lumbar degenerative disease and put forward the clinical stage. METHODS: We retrospectively reviewed 135 patients with foot drop due to lumbar degenerative disease. The clinical features and mechanism were analyzed. Age, sex, duration of palsy, preoperative muscle strength of tibialis anterior (TA, sensation defect of affected lower limb, affected foot, diagnosis and compressed nerve roots were recorded and compared with surgical outcome. RESULTS: Foot drop was observed in 8.1% of all inpatients of lumbar degenerative disease. L5 nerve root compression was observed in 126 of all 135 patients (93.3%. Single, double and triple roots compression was observed respectively in 43, 83, and 9 patients (31.9%, 61.5%, and 6.6%. But there was no significant relationship between preoperative muscle strength of TA and the number of compressed roots. The muscle strength of TA was improved in 113 (83.7% patients after surgery, but it reached to >=4 in only 21 (15.6% patients. Improvement of the muscle strength of TA was almost stable at the 6-month follow-up. At the last follow-up, the muscle strength of TA was 1, 2, 3, 4, 5 respectively in 28, 24, 62, 13, 8 patients. Multivariate logistic regression showed duration of palsy (p=0.0360, OR=2.543, preoperative muscle strength of TA (p=0.0064, OR=5.528 and age (p=0.0309, OR=3.208 were factors that influenced recovery following an operation. CONCLUSIONS: L5 nerve root was most frequently affected. The muscle strength of TA improved in most patients after surgery, but few patients can get a good recovery from foot drop. Patients of shorter duration of palsy, better preoperative muscle strength of TA and younger age showed a better surgical outcome.

    Full Text Available Abstract Background acantholytic squamous cell carcinomas (ASCC and intraoral angiosarcoma share similar histopathological features. Aim of this study was to find marker for a clear distinction. Methods Four oral acantholytic squamous cell carcinomas and one intraoral angiosarcoma are used to compare the eruptive intraoral growth-pattern, age-peak, unfavourable prognosis and slit-like intratumorous spaces in common histological staining as identical clinical and histopathological features. Immunohistochemical staining for pancytokeratin, cytokeratin, collagen type IV, γ2-chain of laminin-5, endothelial differentiation marker CD31 and CD34, F VIII-associated antigen, Ki 67-antigen, β-catenin, E-cadherin, α-smooth-muscle-actin and Fli-1 were done. Results Cytokeratin-immunoreactive cells can be identified in both lesions. The large vascularization of ASCC complicates the interpretation of vascular differential markers being characteristic for angiosarcoma. Loss of cell-cell-adhesion, monitored by loss of E-cadherin and β-catenin membrane-staining, are indetified as reasons for massive expression of invasion-factor ln-5 in ASCC and considered responsible for unfavourable prognosis of ASCC. Expression of Fli-1 in angiosarcoma and cellular immunoreaction for ln-5 in ASCC are worked out as distinguishing features of both entities. Conclusion Fli-1 in angiosarcoma and ln-5 in ASCC are distinguishing features.

    In the absence of pathognomonic clinical features or a definitive laboratory test, multiple sclerosis (MS) remains ultimately a diagnosis of exclusion. Accurate diagnosis is increasingly important with available disease modifying therapy. Unfortunately the rate of misdiagnosis remains around 5%-10%, indicating that 1 in 20 patients thought to have MS has, instead, a condition resembling MS. In this review we describe conditions that may be confused with MS because they can present as lesions disseminated in time, space, or both. Conditions often confused with MS may be inflammatory (systemic lupus erythematosus, Sjögren's syndrome, vasculitis, sarcoidosis, Behçet's disease), infectious (Lyme disease, syphilis, progressive multifocal leukoencephalopathy, HTLV-1 infection, herpes zoster), genetic (lysosomal disorders, adrenoleukodystrophy, mitochondrial disorders, CADASIL), metabolic (vitamin B12 deficiency), neoplastic (CNS lymphoma) and spinal (degenerative and vascular malformations) diseases. The key to the accurate diagnosis of MS is vigilance for atypical features, suggesting the possibility of an alternative diagnosis.

    Introduction Cystic Fibrosis (CF) is an autosomal recessive disorder and the incidence of this disease is undermined in Northern India. The distinguishable salty character of the sweat belonging to individuals suffering from CF makes sweat chloride estimation essential for diagnosis of CF disease. Aim The aim of this prospective study was to elucidate the relationship of sweat chloride levels with clinical features and pattern of CF. Materials and Methods A total of 182 patients, with clinical features of CF were included in this study for quantitative measurement of sweat chloride. Sweat stimulation and collection involved pilocarpine iontophoresis based on the Gibson and Cooks methodology. The quantitative estimation of chloride was done by Schales and Schales method with some modifications. Cystic Fibrosis Trans Membrane Conductance Regulator (CFTR) mutation status was recorded in case of patients with borderline sweat chloride levels to correlate the results and for follow-up. Results Out of 182 patients having clinical features consistent with CF, borderline and elevated sweat chloride levels were present in 9 (5%) and 41 (22.5%) subjects respectively. Elevated sweat chloride levels were significantly associated with wheeze, Failure To Thrive (FTT), history of CF in Siblings, product of Consanguineous Marriage (CM), digital clubbing and steatorrhoea on univariate analysis. On multivariate analysis only wheeze, FTT and steatorrhoea were found to be significantly associated with elevated sweat chloride levels (pCFTR mutations and rest of the three cases were not having any mutation in CFTR gene. Conclusion The diagnosis is often delayed and the disease is advanced in most patients at the time of diagnosis. Sweat testing is a gold standard for diagnosis of CF patients as genetic mutation profile being heterozygous and unlikely to become diagnostic test. PMID:28208841

    Full Text Available INTRODUCTION: Measles that develops in previously vaccinated cases has been reported to be associated with modified disease, although severity has usually been assessed by the presence or absence of symptoms. To date no studies have attempted to subjectively grade the severity of the clinical features. AIM: To investigate both the objective and subjective severity of measles in vaccinated and unvaccinated cases in the context of a community outbreak. METHODS: A retrospective observational cohort study conducted in Christchurch in 2009 using notified data compared the presentation of measles in 14 confirmed cases that had received at least one MMR (measles, mumps, rubella vaccination and 14 age-matched unvaccinated confirmed cases. Additional details on the subjective and objective severity of the illness were obtained from parents/guardians using a standardised telephone questionnaire. RESULTS: The vaccinated group had significantly fewer clinical features on presentation (p=0.01, RR=1.3, 95% CI 1.1-1.6 and a less severe illness objectively, as measured by height and duration of fever, the number of days needing medication other than paracetamol and days required in bed. Unvaccinated cases were 2.8 times more likely to have more severe clinical features than vaccinated cases (OR=2.8, 95% CI 1.5-5.0. Unvaccinated cases were 3.0 times more likely to develop IgM antibody (RR=3.0, 95% CI 0.9-9.3. DISCUSSION: Previously vaccinated children who develop measles are likely to have less severe disease and serology results that may be inconclusive, particularly for IgM antibody if tested in the first few days after the rash onset.

    Full Text Available Context: Brain injuries occurring at a particular time may cause damages in well-defined regions of brain. Perinatal hypoxic ischemic encephalopathy and hypoglycemia are some of the most common types of brain injuries. Neonatal hypoglycemia can cause abnormal myelination in parietal and occipital lobes resulting in parieto-occipital encephalomalacia. There is a small number of studies about clinical and electroencephalographic (EEG features of children with parieto-occipital encephalomalacia. They might have important neurologic sequelae such as cortical visual loss, seizures, and psychomotor retardation. Aims: We aimed to evaluate the causes of parieto-occipital encephalomalacia and evaluate the clinical and electrophysiological features of children with parieto-occipital encephalomalacia. Settings and Design: We evaluated clinical features and EEGs of 27 children with parieto-occipital encephalomalacia. Statistical Analysis Used: Descriptive statistics were used. Results: Hospitalization during the neonatal period was the most common cause (88.9% of parieto-occipital brain injury. Eleven patients (40.7% had a history of neonatal hypoglycemia. Twenty-three patients (85.2% had epilepsy and nine of the epileptic patients (39% had refractory seizures. Most of the patients had bilateral (50% epileptic discharges originating from temporal, parietal, and occipital lobes (56.2%. However, some patients had frontal sharp waves and some had continuous spike and wave discharges during sleep. Visual abnormalities were evident in 15 (55.6% patients. Twenty-two (81.5% had psychomotor retardation. Fine motor skills, social contact and language development were impaired more than gross motor skills. Conclusions: In our study, most of the patients with parieto-occipital encephalomalacia had an eventful perinatal history. Epilepsy, psychomotor retardation, and visual problems were common neurologic complications.

    Full Text Available Introduction: Patients with growth hormone (GH insensitivity (also known as Laron syndome have been reported from the Mediterranean region and Southern Eucador, with few case reports from India. We present here the clinical and endocrine profile of 9 children with Laron syndrome from India. Material and Methods: Nine children diagnosed with Laron syndrome based on clinical features of GH deficiency and biochemical profile suggestive of GH resistance were studied over a period of 5 years from January 2008 to January 2013. Results and Discussion: Age of presentation was between 2.5-11.5 years. All children were considerably short on contemporary Indian charts with mean (SD height Z score -5.2 (1.6. However, they were within ± 2 SD on Laron charts. No child was overweight [mean (SD BMI Z score 0.92 (1.1]. All children had characteristic facies of GH deficiency with an added feature of prominent eyes. Three boys had micropenis and 1 had unilateral undescended testis. All children had low IGF-1 (<5 percentile and IGFP-3 (<0.1 percentile with high basal and stimulated GH [Basal GH mean (SD = 13.78 (12.75 ng/ml, 1-h stimulated GH mean (SD = 46.29 (25.68 ng/ml]. All children showed poor response to IGF generation test. Conclusion: Laron syndrome should be suspected in children with clinical features of GH deficiency, high GH levels and low IGF-1/IGFBP-3. These children are in a state of GH resistance and need IGF-1 therapy.

    Full Text Available Background and Design: Classic Kaposi sarcoma (KS occurs predominantly among the elderly, with Jews, Italians and Greeks. Classic KS has been seen relatively frequently in Turkey. Our aim was to evaluate the demographic, clinical features of Kaposi sarcoma and etiopathological role of human herpesvirus-8 (HHV-8. Treatment results of 18 classic Kaposi’s sarcoma were also concluded.Material and Method: Eighteen cases of classic Kaposi sarcoma diagnosed as clinically and histopathologically between January 2001 and August 2008 in our dermatology department were taken to this study. Demographic, clinical features and treatment results were reviewed retrospectively in all patients. HHV-8 was investigated in the lesional skin of 7 patients.Results: A male/female ratio of 2/1 was found. Mean age at diagnosis was 67.2 (37-94 years. Bilaterally lower extremities were involved in 15 patients (83.3%, the trunk was involved in 3 patients (16.6%. Plaques and nodules were the common type of lesions (66.6% and 55.5%. Nine patients had no symptoms (50%. Edema was the most common symptom (38.8%. A second primary malignancy was found in 2 patients (11.1%. HHV-8 was detected in 6 of the 7 patients(85.7%. Majority of the patients were treated with interferon alfa (subcutaneously and cryotherapy as a monotherapy or a combination therapy. Imiquimod was the second agent in combined treatment (27.7%. Conclusion: We suggest that interferon alfa and imiquimod can be used as first line therapy agents with their antiviral and immunmodulatuar features in the treatment of KKS.

    Purpose Epilepsy is common in sub-Saharan Africa (SSA), but the clinical features and consequences are poorly characterized. Most studies are hospital-based, and few studies have compared different ecological sites in SSA. We described active convulsive epilepsy (ACE) identified in cross-sectional community-based surveys in SSA, to understand the proximate causes, features, and consequences. Methods We performed a detailed clinical and neurophysiologic description of ACE cases identified from a community survey of 584,586 people using medical history, neurologic examination, and electroencephalography (EEG) data from five sites in Africa: South Africa; Tanzania; Uganda; Kenya; and Ghana. The cases were examined by clinicians to discover risk factors, clinical features, and consequences of epilepsy. We used logistic regression to determine the epilepsy factors associated with medical comorbidities. Key Findings Half (51%) of the 2,170 people with ACE were children and 69% of seizures began in childhood. Focal features (EEG, seizure types, and neurologic deficits) were present in 58% of ACE cases, and these varied significantly with site. Status epilepticus occurred in 25% of people with ACE. Only 36% received antiepileptic drugs (phenobarbital was the most common drug [95%]), and the proportion varied significantly with the site. Proximate causes of ACE were adverse perinatal events (11%) for onset of seizures before 18 years; and acute encephalopathy (10%) and head injury prior to seizure onset (3%). Important comorbidities were malnutrition (15%), cognitive impairment (23%), and neurologic deficits (15%). The consequences of ACE were burns (16%), head injuries (postseizure) (1%), lack of education (43%), and being unmarried (67%) or unemployed (57%) in adults, all significantly more common than in those without epilepsy. Significance There were significant differences in the comorbidities across sites. Focal features are common in ACE, suggesting identifiable and

    Full Text Available Pernicious anemia is an autoimmune disease with a variety of clinical presentations. We describe a case of pernicious anemia presenting with pancytopenia with hemolytic features. Further workup revealed very low vitamin B12 levels and elevated methylmalonic acid. It is important for a general internist to identify pernicious anemia as one of the cause of pancytopenia and hemolytic anemia to avoid extensive workup. Pernicious anemia can present strictly with hematological abnormalities without neurological problems or vice versa as in our case.

    We conducted a retrospective study comparing the presenting clinical and biologic features of 64 children who had septic arthritis caused by Kingella kingae with 26 children who had septic arthritis caused by Staphylococcus aureus. Children with K. kingae septic arthritis were significantly younger than those with S. aureus septic arthritis. Otherwise, there were no significant differences between the 2 groups with respect to fever, location, white blood cell count, synovial fluid cell count, C-reactive protein, or serum fibrinogen. However, the clinical course was significantly better for children with septic arthritis caused by K. kingae as evidenced by shorter hospitalization and fewer adverse events. Presumptive antibiotic therapy for septic arthritis in young infants should take into account both of these pathogens, even in case of mild presentation.

    We report a clinical and neuroradiological description of a severe case of Wernicke's encephalopathy in a surgical patient. After colonic surgery for neoplasm, he was treated for a long time with high glucose concentration total parenteral nutrition. In the early post-operative period, the patient showed severe encephalopathy with ataxia, ophthalmoplegia and consciousness disorders. We used magnetic resonance imaging (MRI) to confirm the clinical suspicion of Wernicke's encephalopathy. The radiological feature showed hyperintense lesions which were symmetrically distributed along the bulbo-pontine tegmentum, the tectum of the mid-brain, the periacqueductal grey substance, the hypothalamus and the medial periventricular parts of the thalamus. This progressed to typical Wernicke-Korsakoff syndrome with ataxia and memory and cognitive defects. Thiamine deficiency is a re-emerging problem in non-alcoholic patients and it may develop in surgical patients with risk factors such as malnutrition, prolonged vomiting and long-term high glucose concentration parenteral nutrition.

    Callosal anomalies are frequently associated with other central nervous system (CNS) and/or somatic anomalies. We retrospectively analyzed the clinical features of corpus callosal agenesis/hypoplasia accompanying other CNS and/or somatic anomalies. We reviewed the imaging and clinical information of patients who underwent brain magnetic resonance imaging in our hospital, between 2005 and 2012. Callosal anomalies were isolated in 13 patients, accompanied by other CNS anomalies in 10 patients, associated with only non-CNS somatic anomalies in four patients, and with both CNS and non-CNS abnormalities in four patients. Out of 31 patients, four developed normally, without impairments in motor or cognitive functions. Five of nine patients with cerebral palsy were accompanied by other CNS and/or somatic anomalies, and showed worse Gross Motor Function Classification System scores, compared with the other four patients with isolated callosal anomaly. In addition, patients with other CNS anomalies also had a higher seizure risk.

    Four cases of bilateral internal carotid occlusion are reported with respect to clinical features, hemodynamics and various image diagnosis. MRI is applied to three cases. The patients comprised 2.08 % of all cerebral occlusive diseases treated during the past five years at our clinic. One case is of abrupt onset and three cases are progressing profiles. In one of these cases, collateral circulation is supplied mainly by leptomeningeal anastomosis of the posterior cerebral artery and posterior pericallosal artery branching from the basilar artery. In two of them, they are supplied through the circle of Willis. Middle cerebral artery occlusion, occlusion supra occlusionem, however, causes decisive ischemic lesion in its teritory. Applying MRI, complicated ischemic lesions, such as lacunar infarction, paraventricular lesion, deep white matter lesion and border zone infarction can clearly be identified. In the case of total aphasia, the lesions responsible are demonstrated clearly by MRI, but only vaguely by X-ray CT.

  19. Clinical features of bacterial vaginosis in a murine model of vaginal infection with Gardnerella vaginalis.

    Directory of Open Access Journals (Sweden)

    Nicole M Gilbert

    Full Text Available Bacterial vaginosis (BV is a dysbiosis of the vaginal flora characterized by a shift from a Lactobacillus-dominant environment to a polymicrobial mixture including Actinobacteria and gram-negative bacilli. BV is a common vaginal condition in women and is associated with increased risk of sexually transmitted infection and adverse pregnancy outcomes such as preterm birth. Gardnerella vaginalis is one of the most frequently isolated bacterial species in BV. However, there has been much debate in the literature concerning the contribution of G. vaginalis to the etiology of BV, since it is also present in a significant proportion of healthy women. Here we present a new murine vaginal infection model with a clinical isolate of G. vaginalis. Our data demonstrate that this model displays key features used clinically to diagnose BV, including the presence of sialidase activity and exfoliated epithelial cells with adherent bacteria (reminiscent of clue cells. G. vaginalis was capable of ascending uterine infection, which correlated with the degree of vaginal infection and level of vaginal sialidase activity. The host response to G. vaginalis infection was characterized by robust vaginal epithelial cell exfoliation in the absence of histological inflammation. Our analyses of clinical specimens from women with BV revealed a measureable epithelial exfoliation response compared to women with normal flora, a phenotype that, to our knowledge, is measured here for the first time. The results of this study demonstrate that G. vaginalis is sufficient to cause BV phenotypes and suggest that this organism may contribute to BV etiology and associated complications. This is the first time vaginal infection by a BV associated bacterium in an animal has been shown to parallel the human disease with regard to clinical diagnostic features. Future studies with this model should facilitate investigation of important questions regarding BV etiology, pathogenesis and

    Background: Neuromyelitis optica spectrum disorder (NMOSD) was long believed to be an aggressive form of multiple sclerosis (MS). This study aimed to describe the clinical features of patients with MS and NMOSD to assist in differential diagnoses in clinical practice. Methods: Data including the patients’ serum and cerebrospinal fluid (CSF) tests, image findings, and clinical information from 175 patients with MS or NMOSD at Xuanwu Hospital, Capital Medical University from November 2012 to May 2014 were collected and analyzed retrospectively. An enzyme-linked immunosorbent assay was performed to detect the myelin oligodendrocyte glycoprotein (MOG) autoantibodies in CSF and serum. Cell-based assays were used to detect aquaporin-4-antibody (AQP4-Ab). The Chi-square test was used to compare the categorical variables. Wilcoxon rank sum test was performed to analyze the continuous variables. Results: Totally 85 MS patients (49%) and 90 NMOSD patients (51%) were enrolled, including 124 (71%) women and 51 (29%) men. Fewer MS patients (6%) had autoimmune diseases compared to NMOSD (19%) (χ2 = 6.9, P < 0.01). Patients with NMOSD had higher Expanded Disability Status Scale scores (3.5 [3]) than MS group (2 [2]) (Z = −3.69, P < 0.01). The CSF levels of white cell count and protein in both two groups were slightly elevated than the normal range, without significant difference between each other. Positivity of serum AQP4-Ab in NMOSD patients was higher than that in MS patients (MS: 0, NMOSD: 67%; χ2 = 63.9, P < 0.01). Oligoclonal bands in CSF among NMOSD patients were remarkably lower than that among MS (MS: 59%, NMOSD: 20%; χ2 = 25.7, P < 0.01). No significant difference of MOG autoantibodies was found between the two groups. Conclusion: The different CSF features combined with clinical, magnetic resonance imaging, and serum characteristics between Chinese patients with MS and NMOSD could assist in the differential diagnosis.

    Full Text Available Objective To summarize the clinical features, serologic, cerebrospinal fluid (CSF tests in patients with neurosyphilis at different stages.  Methods A retrospective analysis was made on the clinical features, imaging, serologic and CSF tests, treatment and prognosis of 12 cases diagnosed as neurosyphilis. In those cases, 5 cases were early-stage neurosyphilis, including 4 syphilitic meningitis (meningomyelitis and one meningovascular syphilis; 7 cases were late-stage neurosyphilis, all of whom were general paresis.  Results The serum Treponema pallidum antibody (TP-Ab and rapid plasma regain (RPR tests were positive in all 12 cases. The CSF TP-Ab tests of 12 cases were all positive and CSF RPR tests were positive in 9 cases. In 5 cases of early-stage neurosyphilis, one case had elevated intracranial pressure (ICP, 3 cases presented with elevated white blood cell (WBC, 4 cases had elevated protein concentration. In 7 cases of late-stage neurosyphilis, one case had elevated ICP, 7 cases presented with elevated WBC and protein concentration. CSF cytology showed lymphocyte reaction, mainly small lymphocytes. All cases were treated with different doses of intravenous penicillin or ceftriaxone sodium by intramuscular injection, among whom 8 cases presented improved neuropsychiatric symptoms, while 4 cases had no significant improvement.  Conclusions Neurosyphilis is easy to be misdiagnosed because of various styles of onset and nontypical clinical manifestations. A definite diagnosis depends on clinical manifestations and serologic and CSF examinations. Early diagnosis and standard treatment is essential for improving prognosis and reducing complications. DOI: 10.3969/j.issn.1672-6731.2016.07.005

    Objective To assess the differences in incidence, clinical features, current treatment strategies and outcome in patients with type-2vs. type-1 acute myocardial infarction (AMI).Methods We included 824 consecutive patients with a diagnosis of type-1 or type-2 AMI. Dur-ing index hospitalization, clinical features and treatment strategies were collected in detail. At 1-year follow-up, mortality, stroke, non-fatal myocardial infarction and major bleeding were recorded.ResultsType-1 AMI was present in 707 (86%) of the cases while 117 (14%) were classified as type-2. Patients with type-2 AMI were more frequently female and had higher co-morbidities such as diabetes, previous non-ST segment elevation acute coronary syndromes, impaired renal function, anaemia, atrial fibrillation and malignancy. However, preserved left ventricular ejection fraction and normal coronary arteries were more frequently seen, an invasive treatment was less common, and anti-platelet medications, statins and beta-blockers were less prescribed in patients with type-2 AMI. At 1-year follow-up, type-2 AMI was associated with a higher crude mortality risk (HR: 1.75, 95% CI: 1.14-2.68;P = 0.001), but this association did not remain significant after multivariable adjustment (P = 0.785). Furthermore, we did not find type-2 AMI to be associated with other clinical outcomes.Conclusions In this real-life population, compared with type-1, type-2 AMI were predominantly women and had more co-morbidities. Invasive treatment strategies and cardioprotective medications were less used in type-2, while the 1-year clinical outcomes were similar.

    During the H1N1 influenza pandemic (pH1N1/09) diagnostic algorithms were developed to guide antiviral provision. However febrile illnesses are notoriously difficult to distinguish clinically. Recent evidence highlights the importance of incorporating travel history into diagnostic algorithms to prevent the catastrophic misdiagnosis of life-threatening infections such as malaria. We applied retrospectively the UK pH1N1/09 case definition to a unique cohort of healthy adult volunteers exposed to Plasmodium falciparum malaria or influenza to assess the predictive value of this case definition, and to explore the distinguishing clinical features of early phase infection with these pathogens under experimental conditions. For influenza exposure the positive predictive value of the pH1N1/09 case definition was only 0.38 (95% CI: 0.06-0.60), with a negative predictive value of 0.27 (95% CI: 0.02-0.51). Interestingly, 8/11 symptomatic malaria-infected adults would have been inappropriately classified with influenza by the pH1N1/09 case definition, while 5/8 symptomatic influenza-exposed volunteers would have been classified without influenza (P = 0.18 Fisher's exact). Cough (P = 0.005) and nasal symptoms (P = 0.001) were the only clinical features that distinguished influenza-exposed from malaria-exposed volunteers. An open mind regarding the clinical cause of undifferentiated febrile illness, particularly in the absence of upper respiratory tract symptoms, remains important even during influenza pandemic settings. These data support incorporating travel history into pandemic algorithms.

    Background Angina without significant stenosis, or nonobstructive coronary artery disease, attracts clinical attention. Microvascular coronary artery spasm (microvascular CAS) can cause nonobstructive coronary artery disease. We investigated the clinical features of microvascular CAS and the therapeutic efficacy of calcium channel blockers. Methods and Results Three hundred seventy consecutive, stable patients with suspected angina presenting nonobstructive coronary arteries (<50% diameter) in coronary angiography were investigated with the intracoronary acetylcholine provocation test, with simultaneous measurements of transcardiac lactate production and of changes in the quantitative coronary blood flow. We diagnosed microvascular CAS according to lactate production and a decrease in coronary blood flow without epicardial vasospasm during the acetylcholine provocation test. We prospectively followed up the patients with calcium channel blockers for microvascular coronary artery disease. We identified 50 patients with microvascular CAS who demonstrated significant impairment of the endothelium-dependent vascular response, which was assessed by coronary blood flow during the acetylcholine provocation test. Administration of isosorbide dinitrate normalized the abnormal coronary flow pattern in the patients with microvascular CAS. Multivariate logistic regression analysis indicated that female sex, a lower body mass index, minor–borderline ischemic electrocardiogram findings at rest, limited–baseline diastolic-to-systolic velocity ratio, and attenuated adenosine triphosphate–induced coronary flow reserve were independently correlated with the presence of microvascular CAS. Receiver-operating characteristics curve analysis revealed that the aforementioned 5-variable model showed good correlation with the presence of microvascular CAS (area under the curve: 0.820). No patients with microvascular CAS treated with calcium channel blockers developed cardiovascular

    AIM: There is still no accepted conclusion regarding the clinical features and related risk factors of patients with fatty liver. The large-scale clinical studies have not carried out yet in Guangzhou area. The aim of the present study was to investigate the clinical features and related risk factors of patients with fatty liver in Guangzhou area. METHODS: A total of 413 cases with fatty liver were enrolled in the study from January 1998 to May 2002. Retrospective case-control study was used to evaluate the clinical featuresand related risk factors of fatty liver with logistic regression.RESULTS: Obesity (OR: 21.204), alcohol abuse (OR: 18.601),type 2 diabetes mellitus (OR: 4.461), serum triglyceride (TG)(OR: 3.916), serum low-density lipoprotein cholesterol (LDL-C)(OR: 1.840) and fasting plasma glucose (FPG) (OR: 1.535)were positively correlated to the formation of the fatty liver. The levels of serum alanine aminotransferase (ALT) and gammaglutamyltransferase (GGT) increased mildly in the patients withfatty liver and were often less than 2-fold of the normal limit.The higher abnormalities of aspartate aminotransferase (AST)levels (42.9%) with Asr/ALT more than 2(17.9%) were found in patients with alcoholic fatty liver (AFL) than those with nonalcoholic fatty liver (NAFL) (16.9% and 5.0% respectively). The elevation of serum TG, cholesterol (CHOL), LDL-C was more common in patients with NAFL than with AFL.CONCLUSION: Obesity, alcohol abuse, type 2 diabetes mellitus and hyperlipidemia may be independent risk factors of fatty liver. The mildly abnormal hepatic functions can be found in patients with fatty liver. More obvious damages of liver function with AST/ALT usually more than 2 were noted in patients with AFL.

    Spinal muscular atrophy with respiratory distress (SMARD1) is an autosomal recessive neuromuscular disease caused by mutations in the IGHMBP2 gene, encoding the immunoglobulin μ-binding protein 2, leading to motor neuron degeneration. It is a rare and fatal disease with an early onset in infancy in the majority of the cases. The main clinical features are muscular atrophy and diaphragmatic palsy, which requires prompt and permanent supportive ventilation. The human disease is recapitulated in the neuromuscular degeneration (nmd) mouse. No effective treatment is available yet, but novel therapeutical approaches tested on the nmd mouse, such as the use of neurotrophic factors and stem cell therapy, have shown positive effects. Gene therapy demonstrated effectiveness in SMA, being now at the stage of clinical trial in patients and therefore representing a possible treatment for SMARD1 as well. The significant advancement in understanding of both SMARD1 clinical spectrum and molecular mechanisms makes ground for a rapid translation of pre-clinical therapeutic strategies in humans.

    In clinically severe cervical spondylosis, imaging plays a vital role in surgical decisions. A prime factor is acquired canal stenosis with cord compression. To validate this concept, the clinical and imaging features of 20 patients with spondylitic myelopathy and 24 with radiculopathy were retrospectively reviewed. All had computed tomographic myelography (CTM) as part of their clinical work-up. The patients` clinical severity was graded as mild, moderate and severe; the age, length of illness and a history of eventual surgery or otherwise were recorded. At the level of maximum compression the following parameters were obtained from the axial CTM images: surface area and ratio of the anteroposterior to the transverse diameter of the cord; subarachnoid space and vertebral canal areas. Data were statistically analysed. A significant association exists between surgery and increasing severity of symptoms (P=0.04), and advancing age (P=0.01). These associations hold true for myelopathy and radiculopathy. A strong association is present between surgery and the surface area of the cord (P=0.01), being applicable to myelopathy only. The other parameters show no association with surgical decisions. It is concluded that with myelopathy a narrow cord area at the level of maximum compression, and moderate-severe functional impairment are indicators for surgical intervention.

    Bacillus cereus is the second most frequent cause of post-traumatic bacterial endophthalmitis. Although genotyping of B. cereus associated with gastrointestinal infections has been reported, little is known about the B. cereus clinical isolates associated with post-traumatic endophthalmitis. This is largely due to the limited number of clinical strains available isolated from infected tissues of patients with post-traumatic endophthalmitis. In this study, we report successful isolation of twenty-four B. cereus strains from individual patients with different disease severity of post-traumatic endophthalmitis. Phylogenetic analysis showed that all strains could be categorized into three genotypes (GTI, GTII and GTIII) and the clinical score showed significant differences among these groups. We then further performed genotyping using the vrrA gene, and evaluated possible correlation of genotype with the clinical features of B. cereus-caused post-traumatic endophthalmitis, and with the prognosis of infection by conducting follow-up with patients for up to 2 months. We found that the disease of onset and final vision acuity were significantly different among the three groups. These results suggested that the vrrA gene may play a significant role in the pathogenesis of endophthalmitis, and genotyping of B. cereus has the potential for predicting clinical manifestation and prognosis of endophthalmitis. To the best of our knowledge, this is the first report of isolation of large numbers of clinical isolates of B. cereus from patients with endophthalmitis. This work sets the foundation for future investigation of the pathogenesis endophthalmitis caused by B. cereus infection.

    Full Text Available Genomics is expanding the horizons of epidemiology, providing a new dimension for classical epidemiological studies and inspiring the development of large-scale multicenter studies with the statistical power necessary for the assessment of gene-gene and gene-environment interactions in cancer etiology and prognosis. This paper describes the methodology of the Clinical Genome of Cancer Project in São Paulo, Brazil (CGCP, which includes patients with nine types of tumors and controls. Three major epidemiological designs were used to reach specific objectives: cross-sectional studies to examine gene expression, case-control studies to evaluate etiological factors, and follow-up studies to analyze genetic profiles in prognosis. The clinical groups included patients' data in the electronic database through the Internet. Two approaches were used for data quality control: continuous data evaluation and data entry consistency. A total of 1749 cases and 1509 controls were entered into the CGCP database from the first trimester of 2002 to the end of 2004. Continuous evaluation showed that, for all tumors taken together, only 0.5% of the general form fields still included potential inconsistencies by the end of 2004. Regarding data entry consistency, the highest percentage of errors (11.8% was observed for the follow-up form, followed by 6.7% for the clinical form, 4.0% for the general form, and only 1.1% for the pathology form. Good data quality is required for their transformation into useful information for clinical application and for preventive measures. The use of the Internet for communication among researchers and for data entry is perhaps the most innovative feature of the CGCP. The monitoring of patients' data guaranteed their quality.

    Full Text Available Abstract Objective: This study aimed to critically review the literature available regarding the Zika virus outbreak in Brazil and its possible association with microcephaly cases. Sources: Experts from Instituto do Cérebro do Rio Grande do Sul performed a critical (nonsystematic literature review regarding different aspects of the Zika virus outbreak in Brazil, such as transmission, epidemiology, diagnostic criteria, and its possible association with the increase of microcephaly reports. The PubMed search using the key word “Zika virus” in February 2016 yielded 151 articles. The manuscripts were reviewed, as well as all publications/guidelines from the Brazilian Ministry of Health, World Health Organization and Centers for Disease Control and Prevention (CDC – United States. Summary of findings: Epidemiological data suggest a temporal association between the increased number of microcephaly notifications in Brazil and outbreak of Zika virus, primarily in the Brazil's Northeast. It has been previously documented that many different viruses might cause congenital acquired microcephaly. Still there is no consensus on the best curve to measure cephalic circumference, specifically in preterm neonates. Conflicting opinions regarding the diagnosis of microcephaly (below 2 or 3 standard deviations that should be used for the notifications were also found in the literature. Conclusion: The development of diagnostic techniques that confirm a cause–effect association and studies regarding the physiopathology of the central nervous system impairment should be prioritized. It is also necessary to strictly define the criteria for the diagnosis of microcephaly to identify cases that should undergo an etiological investigation.

    The Ipubi Formation in the Araripe Basin (Northeast Brazil) has evaporite-lutite successions rich in gypsum, a mineral of great regional economic relevance, a highlighted stratigraphic mark, and also a natural boundary for underlying successions potentially analogous to "Pre-Salt" hydrocarbon reservoirs of the Brazilian coastal basins. In this study, syngenetic and diagenetic aspects of the Ipubi Formation at Santana do Cariri (Ceará State) were investigated by means of facies analysis, petrography, and mineralogical/chemical analyses of evaporites and shales. The results show that the contact relationship between evaporites and marly shales, without signs of subaerial exposure and laterally adjacent, was associated with shallow, calm and somewhat anoxic waterbodies, locally salt-supersaturated (brines) but under seasonal variations of water levels. This scenario could have shared place with hydrothermal phenomena in a playa lake depositional system. Regarding diagenesis, although there is evidence supporting pseudomorphic replacement of gypsum by anhydrite, the burial of the Ipubi Formation would have been limited due to the frequent occurrence of gypsum without any trace of chemical replacement.

    This study evaluated the clinical characteristics, treatment outcomes, and complications of patients with adult onset Still's disease (AOSD) in our local Chinese population. Patients with AOSD attending our hospital from 2008 to 2011 were identified and followed up. Their clinical and laboratory features at presentation, as well as their disease progression, treatments, and outcomes were recorded and compared with other reported series. A total of 75 patients with AOSD were identified. Forty-four were female. Thirty-nine had disease onset between 16 and 35 years of age. The most common presenting features were fever (96%), arthritis (57.33%), rash (78.67%), and sore throat (49.3%). The acute phase response was marked in most patients, with elevated erythrocyte sedimentation rates (77.05%) and C-reactive protein levels (84.06%). Hyperferritinemia was present in 74.14% of cases, and serum ferritin (SF) levels declined after treatment in most cases. Liver abnormalities were usually transient, but were more severe in 5 patients. Most patients (92%) required corticosteroid therapy; of these, 33.3% also received disease-modifying antirheumatic drugs or immunosuppressive drugs. Sixty-four and 45.33% patients with AOSD achieved partial and complete remission, respectively, after 2 weeks of treatment, and 92% and 74.67%, respectively, after 1 month. The cumulative relapse rate was 45.3%. Patients with AOSD had complex symptoms with no specific laboratory findings. Reduced SF levels after treatment and liver abnormalities may be used to follow treatment outcome.

    Antiphospholipid syndrome is a relatively recent systemic autoimmune disorder defined by thrombotic events and/or obstetric complications in the presence of persistent elevated antiphospholipid antibodies. It\\'s characterized by a wide spectrum of clinical presentations and virtually any organ system or tissue may be affected by the consequences of vascular occlusion. Diagnosis is sometimes difficult and although classification criteria have been published and revised there remain ongoing issues regarding nomenclature, expanding clinical features, laboratory tests and management and much still has to be done. Cutaneous manifestations are common and frequently the first sign of the disease. Although extremely diverse it\\'s important to know which dermatological findings should prompt consideration of antiphospholipid syndrome and the appropriate management for those patients. Much has been debated about when to consider antiphospholipid syndrome and consensus still does not exist, however in spite of being a diagnostic challenge clinicians should know when to look for antiphospholipid antibodies since an early diagnosis is important to prevent further and serious complications. In this article we focus on the cutaneous features that should raise suspicion on the presence of antiphospholipid syndrome and on the complex management of such patients. Many other dermatological signs related to this syndrome have been described in the literature but only occasionally and without consistency or statistic impact and therefore will not be considered here.

    Background Apelin is an adipokine that contributes to the pathogenesis of type 2 diabetes. The plasma levels of apelin increased in obese patients and diabetic subjects. This study aimed to investigate the effects of apelin genetic variants on type 2 diabetes and related quantitative traits.Methods We selected three single nucleotide polymorphisms (SNPs) that could capture all common variants in APLN gene region and genotyped them in 1892 type 2 diabetic patients and 1808 normal glucose regulation controls. The clinical features related to glucose metabolism were measured in the controls. The comparison of allele and genotype distribution in the cases and controls were performed by using X2 tests. The association between SNPs and quantitative traits were analyzed using Wilcoxon's rank-sum test.Results None of the SNPs or haplotypes showed evidence of association to type 2 diabetes. However, rs2235306 was nominally associated with fasting plasma glucose levels in the male subjects with normal glucose regulation ((4.93±0.03)vs (5.01±0.03) mmol/L, P=0.04). No significant difference was observed between all three SNPs and other variables. Conclusions APLN SNP rs2235306 was associated with fasting plasma glucose levels in males. It suggests that APLN genetic variants may contribute to clinical features related to glucose metabolism in Chinese population.

    Full Text Available Purpose: To report impression cytology findings in specimens obtained from eyes with clinical and confocal microscopic features of Acanthamoeba keratitis (AK. Methods: In this interventional case series, impression cytology was obtained from corneas of patients with clinical and confocal microscopic features indicative of AK. Specimens were stained with Periodic acid-Schiff/Papanicolaou (PAS/PAP and examined for the presence of PAS-reactive Acanthamoeba cysts and/or hyperchromatic pear-shaped trophozoites. All specimens were then decolorized and re-stained with calcofluor white (CFW for the presence of chemofluorescent cysts. Results: Fifty-six eyes of 50 patients with mean age of 25.5±9.3 (range, 17 to 78 years were evaluated. Forty-one (82% cases were female and 51 (91.1% eyes had history of contact lens wear. PAS-reactive Acanthamoeba cysts and/or hyperchromatic pear-shaped trophozoites were identified in 53 eyes (94.6%, 2 of which demonstrated only trophozoitelike structures. CFW staining was able to reveal the presence of chemofluorescent cysts in all 51 specimens (91.1% in which cysts had been demonstrated with PAS/PAP staining. Trophozoites were not detected with CFW due to background staining of the cellulose acetate strip used for impression cytology. Conclusion: Corneal impression cytology, stained with PAS/PAP or with CFW, successfully detects Acanthamoeba and can be employed for early noninvasive diagnosis of AK.

    Mutations in the ganglioside-induced differentiation associated-protein 1 (GDAP1) gene have been associated with both autosomal recessive (AR) and dominant (AD) Charcot-Marie-Tooth (CMT) axonal neuropathy. The relative frequency of heterozygous, dominant mutations in Italian CMT is unknown. We investigated the frequency of dominant mutations in GDAP1 in a cohort of 109 axonal Italian patients by sequencing genomic DNA and search for copy number variations. We also explored correlations with clinical features. All cases had already been tested for variants in common axonal AD genes. Eight patients (7.3%) harbored five already reported heterozygous mutations in GDAP1 (p.Arg120Gly, p.Arg120Trp, p.His123Arg, p.Gln218Glu, p.Arg226Ser). Mutations had different penetrances in the families; the onset of symptoms is in the first decade and progression is slower than usually seen in GDAP1-related AR-CMT. We show that the relative frequency of mutations in GDAP was slightly higher than those observed in MFN2 and MPZ (7.3% vs 6.3% and 5.0%). The relatively milder clinical features and the quite indolent course observed are relevant for prognostic assessment. On the basis of our experience and the data reported here, we suggest GDAP1 as the first gene that should be analysed in Italian patients affected by CMT2.

    In this review, we summarize the status of Trichophyton tonsurans infection in Japan in terms of epidemiology, clinical features, diagnosis and infection control. Since approximately 2000, outbreaks of T. tonsurans infections among combat sports club members have been reported frequently, with the infection then spreading to their friends and family members. The most common clinical features of T. tonsurans infection are tinea corporis, which is difficult to differentiate from eczema, and tinea capitis. Tinea capitis is classified as the seborrheic form, kerion celsi form or "black dot" form, although 90% or more of patients are asymptomatic carriers. The diagnosis of symptomatic T. tonsurans infection is established by potassium hydroxide examination and fungal culture. However, because there are many asymptomatic carriers of T. tonsurans infection, tests using the hairbrush culture method are necessary. An increase in asymptomatic carriers of T. tonsurans makes assessment of the current prevalence of the infection challenging and underscores the importance of educational efforts and public awareness campaigns to prevent T. tonsurans epidemics.

    AIM: To assess the clinical features and prognosis of 151 patients with extrahepatic metastases from primary hepatocellular carcinoma (HCC), and describe the treatment strategy for such patients.METHODS: After the diagnosis of HCC, all 995consecutive HCC patients were followed up at regular intervals and 151 (15.2%) patients were found to have extrahepatic metastases at the initial diagnosis of primary HCC or developed such tumors during the follow-up period. We assessed their clinical features,prognosis, and treatment strategies.RESULTS: The most frequent site of extrahepatic metastases was the lungs (47%), followed by lymph nodes (45%), bones (37%), and adrenal glands (12%).The cumulative survival rates after the initial diagnosis of extrahepatic metastases at 6, 12, 24, and 36 mo were 44.1%, 21.7%, 14.2%, 7.1%, respectively. The median survival time was 4.9 mo (range, 0-37 mo). Fourteen patients (11%) died of extrahepatic HCC, others died of primary HCC or liver failure.CONCLUSION: The prognosis of HCC patients with extrahepatic metastases is poor. With regard to the cause of death, many patients would die of intrahepatic HCC and few of extrahepatic metastases. Although most of HCC patients with extrahepatic metastases should undergo treatment for the primary HCC mainly,treatment of extrahepatic metastases in selected HCC patients who have good hepatic reserve, intrahepatic tumor stage (T0-T2), and are free of portal venous invasion may improve survival.

    To evaluate clinical and imaging features of pediatric thyroid cancer, including BRAF'V{sup 600E} mutation status in papillary thyroid cancer (PTC). We evaluated clinical findings including BRAF''6{sup 00E} status, ultrasound (US), and CT features of 13 pediatric patients with thyroid cancer. US findings were retrospectively analyzed for location, presence of a nodule, echotexture, echogenicity, calcifications, margin, shape, intranodular vascularity and abnormal lymph nodes. CT characteristics of the lesions, including attenuation, calcification, and measured degree of enhancement, were assessed. The patients included three boys and ten girls with a mean age of 15.5 years (range 6-18 years). No patient was exposed to radiation. Palpable neck mass was the most common presentation. Eleven of 13 patients (84.6%) were diagnosed with PTC, and two (15.4%) had follicular thyroid cancer (FTC). Nine of 13 (69.2%) had high T-staging. BRAF{sup V600E} mutations were detected in 30.0% of PTC patients. A diffusely enlarged thyroid with calcifications (n = 2) or nodules (n = 7) was detected on US. All PTC nodules showed malignant US findings and one FTC displayed on indeterminate nodule. Nodules generally showed low attenuation on enhanced CT (n = 11/12). US demonstrated enlarged glands with calcifications or nodules. Diffusely enlarged thyroids with microcalcifications should be evaluated using fine-needle aspiration. A low attenuation nodule was a common finding on enhanced CT.

    Cyclosporin A is associated with an acute encephalopathy including seizures and alterations in mental status, herein referred to as cyclosporin A acute encephalopathy and seizure syndrome. The clinical history, electroencephalogram (EEG), and neuroimaging findings in 19 children with cyclosporin A acute encephalopathy and seizure syndrome over a 10-year period were reviewed in order to delineate clinical characteristics, imaging features, and to determine the risk of seizure recurrence in this population. All 19 had motor seizures associated with other features of cortical and subcortical dysfunction. The acute mean cyclosporin A level was 342 microg/L, but was within the "therapeutic" range in five cases. Brain imaging by computed tomography (CT) or magnetic resonance imaging (MRI) in the acute or subacute phase revealed lesions characteristic of cyclosporin A toxicity in 14 cases. Acute EEG abnormalities were present in all and included epileptiform discharges or focal slowing. Patients were followed for a median of 49 months (1-9 years). Follow-up imaging (n = 10) showed lesion resolution or improvement in the majority while EEG (n = 10) had normalized in only three. Seizures recurred in six patients and only in those with persistent EEG or imaging abnormalities. No patient had a second episode of cyclosporin A associated neurotoxicity or seizure. It appears that a significant risk of seizure recurrence exists following cyclosporin A acute encephalopathy and seizure syndrome and primarily in those children with persistent EEG or imaging abnormalities.

    Full Text Available Abstract Introduction The lateral periodontal cyst, as the name implies, occurs on a lateral periodontal location and is of developmental origin, arising from cystic degeneration of clear cells of the dental lamina. A botryoid odontogenic cyst is considered to be a rare multilocular variant of a lateral periodontal cyst. Case presentation We report the clinical and histopathologic features of a rare case of botryoid odontogenic cyst found in an edentulous area corresponding to the right lower canine of a 64-year-old African-American woman. A multilocular radiolucency was observed, and surgical removal of the lesion revealed a nodule of rubber-like consistency measuring about 1.5 cm in diameter. Cross-sectioning of the nodule showed that it consisted of various cystic compartments. Histologically, various voluminous periodic acid-Schiff-negative clear cells randomly distributed throughout the cystic epithelium were observed, as well as cell layers showing thickenings generally formed by oval, sometimes entangled plaques. The capsule consisted of fibrous connective tissue and showed rare and discrete foci of a perivascular mononuclear inflammatory infiltrate and reactive bone-tissue fragments. The final diagnosis was botryoid odontogenic cyst. Conclusion We provide data that allow the reader to establish the differences between botryoid odontogenic cyst, glandular odontogenic cyst, and lateral periodontal cyst, helping with the differential diagnosis. The reader will have the opportunity to review botryoid odontogenic cyst clinical and histopathologic features, including treatment.

    Heterozygous loss-of-function (LOF) SMAD4 mutations are associated with juvenile polyposis syndrome (JP) and hereditary hemorrhagic telangiectasia (HHT). Some carriers exhibit symptoms of both conditions, leading to the name JP-HHT syndrome. Three families have been reported with connective tissue abnormalities. In order to better understand the spectrum and extent of clinical findings in SMAD4 carriers, medical records of 34 patients (20 families) from five clinical practices were reviewed. Twenty-one percent (7/34) had features suggesting a connective tissue defect: enlarged aortic root (n=3), aortic and mitral insufficiency (n=2), aortic dissection (n=1), retinal detachment (n=1), brain aneurysms (n=1), lax skin and joints (n=1). JP-specific findings were almost uniformly present but variable. Ninety-seven percent had colon polyps that were generally pan-colonic and of variable histology and number. Forty-eight percent (15/31) had extensive gastric polyposis. HHT features were documented in 76% including epistaxis (19/31, 61%), mucocutaneous telangiectases (15/31, 48%), liver arteriovenous malformation (AVM) (6/16, 38%), brain AVM (1/26, 4%), pulmonary AVM (9/17, 53%), and intrapulmonary shunting (14/23, 61%). SMAD4 carriers should be managed for JP and HHT, since symptoms of both are likely yet unpredictable. Connective tissue abnormalities are an emerging component of JP-HHT syndrome, and larger studies are needed to understand these manifestations. PMID:24525918

    Full Text Available Problem. Clinical features of Graves’ hyperthyroidism (GH generally improve during pregnancy and rebound in the postpartum period. It is unclear whether the ophthalmopathy that is associated with GH and, less often, Hashimoto’s thyroiditis (HT changes in parallel with the thyroid associated antibody reactions and clinical features or runs a different course. Method of Study. We retrospectively studied 19 patients with autoimmune thyroid disease over 22 pregnancies: 9 pregnancies with GH and 13 with HT. Ophthalmopathy was defined by NOSPECS class. Results. Thyroid peroxidase (TPO and thyroglobulin (Tg antibody titres decreased during pregnancy and rose in the postpartum period. During pregnancy, 5 patients with GH and 4 patients with HT developed mild ophthalmopathy and two patients with GH and HT developed new upper eyelid retraction (UER. In the postpartum period, eye scores improved in 3 patients with GH and 3 with HT, remained stable in two and 5 patients, respectively, and worsened in 2 patients with GH and one with HT. Conclusions. In patients with mild to moderate eye signs associated with GH and HT, the orbital and thyroid reactions ran different courses during pregnancy. Since no patient had severe ophthalmopathy, we cannot draw definitive conclusions from this preliminary study.

Juvenile-onset AS (JAS with disease onset before 16 years of age differs from adult-onset AS (AAS in many respects. Objective. To compare the clinical features in JAS with different B27 subtypes and analyze the differences between JAS and AAS. Methods. 145 JAS and 360 AAS patients were included. The demographic data, clinical manifestations, laboratory markers, Bath AS indices, and B27 subtypes were recorded. Results. Peripheral arthritis, enthesitis, BASDAI, ESR, and CRP were significantly higher in JAS patients with HLA-B*2704 than those with B27-negative. Enthesitis and ESR were significantly higher in patients with HLA-B*2705 than those with B27-negative. The onset age of HLA-B*2715 group was much earlier than the other groups. The peripheral arthritis, enthesitis, and hip joint involvement in JAS with HLA-B*2704 were significantly higher than those in AAS with HLA-B*2704. Conclusion. JAS with different B27 subtypes had similar features in most of manifestations; JAS and AAS patients with the same subtype could have distinctive courses. Early diagnosis, hip detection, and control of systemic active inflammation in JAS patients will be helpful for improving the prognosis.

    Full Text Available Purpose: Mutations of the a-1 subunit sodium channel gene (SCN1A cause severe myoclonic epilepsy of infancy (SMEI. To date, over 300 mutations related to SMEI have been described. In the present study, we report new SCN1A mutations and the clinical features of SMEI cases. Materials and Methods: We studied the clinical and genetic features of nine patients diagnosed with SMEI at the Pediatric Neurology Department of Istanbul Medical Faculty. Results: Five patients had nonsense mutations, two had missense mutations, one had a splice site mutation and one had a deletion mutation of the SCN1A gene. Mutations at c.3705+5G splice site, p.trip153X nonsense mutation and deletion at c.2416_2946 have not been previously described. The seizures started following whole cell pertussis vaccination in all patients. The seizures ceased in one patient and continued in the other eight patients. Developmental regression was severe in three patients, with frequent status epilepticus. The type of mutation was not predictive for the severity of the disease. Two of the three patients with severe regression had nonsense and missense mutations. Conclusions : Dravet syndrome can be result of several different types of mutation in SCN1A gene. Onset of the seizures after pertussis vaccination is an important clue for the diagnosis and neuro- developmental delay should be expected in all patients.

    Objective: To investigate the clinical and pathological features of idiopathic membranous nephropathy (IMN) in Chinese adults. Methods: From 1986 to 1997, 264 patients with biopsy proven membranous nephropathy were selected in this study. Clinical and pathological features were compared between patients at different ages by t test. Results: (1) Patients from 21- 40 years old were inclined to membranous nephropathy. (2) One hundred and six of the patients had heavy proteinuria at presentation. Hypertension was found in 35 patients. Renal insuffeiency occurred in 7.7% of the patients in renal biopsy. Microscopic hematuria was found in 40.2% of the patients. Seventy-four patients presented nephrotic syndrome. (3) Eight of the 57 patients had deterioration of renal function during an average 49-month follow-up. (4) Patients of stage Ⅰ, Ⅱ, Ⅲ and Ⅳ accounted for 42.3%, 48.7%, 6.0% and 3.0% respectively. Glomeruli IgG, C3 and C1qdeposition was found in 93.2%, 98.8% and 58.3% of the patients. Conclusion: Younger patients are inclined to membranous nephropathy. The incidence of hypertension, microscopic hematuria and renal insuffcieney is similar to that of other countries, while nephrotic syndrome is uncommon.

    Full Text Available A retrospective study of 42 cases of acute flaccid paralysis (AFP in children aged between 7 months and 15 years, registered at the Municipal Clinical Hospital №1 throughout a 7 year period (2007—2014, was performed to investigate the features of pediatric Guillian-Barre Syndrome (GBS. GBS has shown to be the most common cause of AFP in children, with prevalence of 74% of all 31 cases. Clinical manifestations, functional status, laboratory and electrodiagnostic data were evaluated in group of 31 children in order to highlight particular features of childhood GBS in Russia. The highest frequency of GBS was observed in children aged between 1 to 3 with the median 6 [3; 11] years. Boys with GBS outnumbered girls by a 2,1:1 ratio. No seasonal dependence has been observed, with children equally suffering from this disease without a seasonal pattern throughout the year. According to the electrophysiological and clinical data, 24 children were diagnosed with acute inflammatory demyelinating polyradiculoneuropathy (AIDP (77%, 5 with acute motor axonal neuropathy (AMAN (16% and 2 with аcute motor-sensory axonal neuropathy (AMSAN in a total of cases (7%. Several exclusive features of GBS in children for Russia were discovered. The most common initial symptom was limb pain, with the impartial sensory disturbance found only in 13% of the patients observed, 10% of which were paresthesias and the remaining 3% belonging to hypostesias. Children reached the nadir state rapidly, the median time from onset to nadir was 9.5 [6,25; 12,5] days. Cranial nerve dysfunction at nadir was observed in a greater percentage of patients (51% compared to that of 23% cases at the onset, with the facial palsy increasing from 10 to 32% and the bulbar palsy from 12 to 19%. The patients were given intravenous immunoglobulin in various doses: from 0.2 to 1.75 mg/kg per course (0.5 [0.5; 0.8] g/kg and/or plasmapheresis with a median volume of 93 [81; 100] ml/kg per

    Full Text Available Primary focal segmental glomerulosclerosis (FSGS has recently been divided into five subtypes by the Columbia classification. However, little is known about the incidence of these subtypes in the Indian population. In addition, there are very few studies evaluating the clinico-pathologic features with morphometric parameters in these subtypes. This study was aimed at evaluating the clinical, histopathological and morphometric parameters in various subtypes of FSGS at our referral center. Sixty-five (65 cases of idiopathic FSGS, diagnosed over two years (2006-2007, were included in the study. Detailed clinical and biochemical investigations were noted. Histological sections were reviewed and cases classified according to the Columbia classification and various glomerular and tubulo-interstitial features were noted. Glomerular morphometry on digitized images was performed using image analysis software. Renal biopsies with minimal change disease were used as controls for morphometric evaluation. In this study, FSGS not otherwise specified (NOS was the most common subtype (44.6%, followed by perihilar FSGS (24.6%, collapsing (13.8%, tip (12.3% and cellular FSGS (4.6%. Collapsing subtype showed significantly shorter duration of symptoms and higher degree of proteinuria, mean serum urea and creatinine compared with the other subtypes. On histologic analysis, features like glomerular hyalinosis, capsular adhesion, mesangial proliferation and visceral epithelial cell prominence (VEP were frequently seen. The cases with VEP had a shorter duration of symptoms and a higher mean serum creatinine and 24-h urine protein excretion compared with those without VEP. The morphometric study revealed a significant higher mean glomerular area in the NOS, perihilar and collapsing variants as compared with the control biopsies. The present study highlights the differences in the prevalence in the FSGS subtypes in our population compared with the western data. Also, the

    2008-01-01

    Background Serum uric acid (UA), the final product of purine degradation, has been proposed to be a marker for the severity and a possible predictor of mortality in patients with pulmonary arterial hypertension (PAH). The objectives of this study were to elucidate whether serum UA level correlates with the clinical features and the hemodynamic variables in Chinese patients with PAH and to compare the difference of the correlates in patients associated with different etiologies. Methods Serum UA was assessed in 228 patients with three types of PAH (idiopathic PAH (IPAH), congenital heart disease related PAH (CHD-PAH) and connective tissue disease related PAH (CTD-PAH)) together with other clinical features. After the individualized treatment for at least 6 months, the UA levels and clinical features were re-evaluated in 88 patients. Results Serum UA was significantly elevated in patients with PAH compared with age-matched control subjects ((350.40±108.73) μmol/L vs (266.91±81.38) μmol/L), P<0.001). Serum UA negatively correlated with cardiac output and mixed venous saturation (SvO) in all three types of PAH (all P<0.05), positively correlated with the size of right ventricle in IPAH (P=0.002) and CTD-PAH (P=0.013) patients and with pulmonary vascular resistance just in CTD-PAH patients (P=0.001). Serum UA significantly decreased from (365.80±120.46) μmol/L to (333.67±117.56) μmol/L in 88 patients (P=0.006) with vasodilator therapy for at least 6 months, accompanied with a reduction in pulmonary vascular resistance from (15.13±6.96) Woods unit to (12.00±5.04) Woods unit (P=0.001) and an increase in cardiac output from (2.63±0.98) L/min to (3.08±1.04) L/min (P=0.005). Conclusions Serum UA increases in proportion to the clinical severity of all the three types of PAH, especially the CTD-PAH had a stronger correlations compared with IPAH and CHD-PAH. The serum UA levels also could partly reflect the response to the treatment in patients with PAH.

    Combined central and peripheral demyelination (CCPD) is rare, and current knowledge is based on case reports and small case series. The aim of our study was to describe the clinical features, diagnostic results, treatment and outcomes in a large cohort of patients with CCPD. Thirty-one patients entered this retrospective, observational, two-center study. In 20 patients (65%) CCPD presented, after an infection, as myeloradiculoneuropathy, encephalopathy, cranial neuropathy, length-dependent peripheral neuropathy, or pseudo-Guillain-Barré syndrome. Demyelinating features of peripheral nerve damage fulfilling European Federation of Neurological Societies/Peripheral Nerve Society (EFNS/PNS) electrodiagnostic criteria for CIDP were found in 23 patients (74%), and spatial dissemination of demyelinating lesions on brain MRI fulfilling the 2010 McDonald criteria for multiple sclerosis (MS) in 11 (46%). Two thirds of the patients had a relapsing or progressive disease course, usually related to the appearance of new spinal cord lesions or worsening of the peripheral neuropathy, and showed unsatisfactory responses to high-dose corticosteroids and intravenous immunoglobulins. The clinical presentation of CCPD was severe in 22 patients (71%), who were left significantly disabled. Our data suggest that CCPD has heterogeneous features and shows frequent post-infectious onset, primary peripheral nervous system or central nervous system involvement, a monophasic or chronic disease course, inadequate response to treatments, and a generally poor outcome. We therefore conclude that the current diagnostic criteria for MS and CIDP may not fully encompass the spectrum of possible manifestations of CCPD, whose pathogenesis remains largely unknown.

    Full Text Available Abstract Background Several enzyme-linked immunosorbent assay (ELISA-kits are commercially available for the rapid diagnosis of dengue infection, and have demonstrated good sensitivity and specificity in paired serum samples. In practice, however, often only one blood sample is available from febrile travellers returning from dengue endemic areas. Methods To evaluate the diagnostic value of positive dengue antibody-titres performed by a standard ELISA (PanBio IgM- and IgG-ELISA in single serum samples (regarded as "probable infection", 127 positive samples were further analyzed using envelope/membrane IgM-, and nonstructural protein 1 IgM- and IgG-ELISAs, immunofluorescence assays, and real-time reverse transcription polymerase chain reaction assays (RT-PCR. A combination of the test-results served as the diagnostic "gold standard". A total of 1,035 febrile travellers returning from dengue-endemic countries with negative dengue-serology and RT-PCR served as controls to compare clinical and haematological features. Results Overall, only 64 (positive predictive value = 50% of the probable cases were confirmed by additional analysis and 54 (42.5% were confirmed to be "false-positive". Rash was the only clinical feature significantly associated with confirmed dengue fever. The combination of thrombocytopenia and leucopenia was present in 40.4% of confirmed and in 6.1% of false-positive cases. Thus, the positive predictive value for the combination of positive PanBio-ELISA plus the two haematological features was 90.5%. Conclusion The examination of paired serum samples is considered the most reliable serodiagnostic procedure for dengue. However, if only one blood sample is available, a single positive ELISA-result carries a high rate of false-positivity and should be confirmed using a second and more specific diagnostic technique. In the absence of further testing, platelet and white blood cell counts are helpful for the correct interpretation.

    Full Text Available Mild hand, foot and mouth disease (HFMD is at a critical stage owing to its ease of communicability and a higher risk of developing severe complications and death. Clinical diagnosis of mild HFMD was made by the presenting symptoms and signs (symptoms in brief alone. We aim to evaluate the frequencies of symptoms in a retrospective case series study.We collected epidemiological, demographic, clinical, and laboratory data from outpatient and inpatient settings on the clinical data warehouse system. We principally described the frequencies of symptoms of mild HFMD. Correlations between symptoms with laboratory-confirmed cases were then analyzed.The clinical data warehouse system included 3649 probable cases, between 2010 and 2012, of which 956 (26.20% were laboratory confirmed. The peak incidence was identified in children 2 years of age. A total of 370 of the 956 laboratory confirmed cases (38.70% were associated with enterovirus 71 (EV71. Logistic regression analysis adjusted for geographical variables, age, sex, month of onset, and time from onset to diagnosis showed that the clinical features constipation (P<0.0001; adjusted OR, 95%CI (2.99, 2.28-3.91, and blisters (P<0.0001; adjusted OR, 95%CI (2.16, 1.82-2.56 were positively correlated with the confirmed cases.This is the largest case series study, including all the guideline-mentioned symptoms of mild HFMD. Our findings suggest that blisters and constipation should be considered as potential warning signs while front-line clinicians manage surges of children diagnosed with mild HFMD during a pandemic.

Patients and methods: We retrospectively reviewed the medical records of 30 patients with primary SRED (without any comorbid sleep disorders and who were not taking any possible causative medications, and ten patients with drug-induced SRED (occurrence of SRED episodes after starting nightly medication of sedative drugs, which completely resolved after dose reduction or discontinuation of the sedatives. Results: All patients with drug-induced SRED took multiple types of sedatives, such as benzodiazepines or benzodiazepine receptor agonists. Clinical features of drug-induced SRED compared with primary SRED were as follows: higher mean age of onset (40 years old in drug-induced SRED vs 26 years old in primary SRED, significantly higher rate of patients who had total amnesia during most of their SRED episodes (75.0% vs 31.8%, significantly lower rate of comorbidity of night eating syndrome (0% vs 63.3%, and significantly lower rate of history of sleepwalking (10.0% vs 46.7%. Increased doses of benzodiazepine receptor agonists may be responsible for drug-induced SRED. Conclusion: The clinical features of drug-induced SRED were different from those of primary SRED, possibly reflecting differences in the underlying mechanisms between these two categories of SREDs.

    Matthieu Lafaurie

    Full Text Available OBJECTIVES: Clinical features and risk factors for atazanavir (ATV-associated urolithiasis have not been fully investigated. METHODS: We reviewed all cases of ATV-containing urolithiasis identified by infrared spectrophotometry among HIV-infected patients over a 5-year period to describe their clinical features and outcome. A case-control study was performed to identify risk factors associated with ATV-associated urolithiasis using univariate and multivariate logistic regression analyses. RESULTS: 30 cases of ATV-associated urolithiasis were analyzed. Patients were mostly men (87%, median age: 45.5 years, median CD4 cell count: 443 cells/µL and 97% had plasma HIV RNA level <50 cp/mL. Median time between the initiation of ATV-containing regimen and the diagnosis of urolithiasis was 3.1 years. Patients presented with flank pain in 90% and macroscopic hematuria in 82.6%, 34% had renal dysfunction and 44.8% needed ureteroscopic treatment. In univariate analysis, chronic hepatitis C, a history of urolithiasis, prior use of indinavir, ATV duration, undetectable plasma HIV RNA, use of ritonavir as a booster and serum free bilirubin level were associated with ATV-urolithiasis. Multivariate models retained serum free bilirubin level (OR: 2.31, p<0.02 and either ATV duration (OR:  = 1.42, p = <0.03 or a history of urolithiasis (OR = 4.79, p<0.02 when adjusting on serum free bilirubin level as risk factors associated with urolithiasis. CONCLUSIONS: ATV-containing urolithiasis are associated with frank clinical symptoms and may require surgical intervention. A high serum bilirubin level, a long exposure to ATV and a history of urolithiasis are risk factors for this rare adverse event.

    Full Text Available Objective  To study the clinical features, laboratory results and image characteristics of meningeal carcinomatosis (MC. Methods  The clinical data, laboratory and image results, and cerebrospinal fluid (CSF findings of 29 cases diagnosed as MC were retrospectively reviewed and analyzed. Results  Lung cancer is more common as the primary malignancy in MC patients [16(55.2%]. The earliest neurological symptoms varied in MC patients, and headache was the most common symptom (58.6%, followed by epilepsy (13.8%, vision loss (10.3%, neuralgia (6.8%, hearing loss (6.8% and hoarseness (3.4%, and a part of MC patients presented some serious complications. Examination of CSF of MC patients revealed an increase in intracranial pressure, and the presence of white blood cells, red blood cells and increased protein content, while the contents of glucose and chlorides decreased. The content of carcinoembryonic antigen (CEA increased obviously, and CSF cytological exam was found to be positive in 26% patients. Head CT may not helpful for the diagnosis of the MC. The enhanced brain MRI scanning may reveal abnormal enhancement of piamater in 94.7% of MC patients, with diffuse enhancement in 94.4% of cases occurring mostly in piamater and subarachnoid space. Conclusions  MC is an unique form of brain metastases of malignant tumor. The clinical feature are varied and lack of specificity. Enhanced brain MRI scanning and CSF examination may provide some value for diagnosis. Meningeal metastasis is one of the most critical complications resulting in high mortality. Early diagnosis of MC followed by enhanced treatment can prolong survival time and improve patients' prognosis. DOI: 10.11855/j.issn.0577-7402.2016.03.09

    ABSTRACT Objectives. To describe (i) the clinical characteristics of workers, exposed to hymenoptera stings, with an ascertained diagnosis of Hymenoptera Venom Allergy (HVA), (ii) the specific role of occupational exposure, (iii) the effect of Venom Immunotherapy (VIT) in reducing the severity of allergic episodes in workers exposed to repeated stings of hymenoptera, and (iv) the management of the occupational consequences caused by allergic reactions due to hymenoptera stings. Methods. Between 2000 and 2013 an observational study, including patients referred to the regional reference hospital of Liguria, Italy, with an ascertained diagnosis of HVA and treated with VIT, was performed. A structured questionnaire was administered to all patients to investigate the occupational features of allergic reactions. These were graded according to standard systems in patients at the first episode, and after re-stings, during VIT. Results. One-hundred and 8four out of the 202 patients referred had a complete data set. In 32 (17.4%) patients, the allergic reaction occurred during work activities performed outdoor. Of these, 31.2% previously stung by hymenoptera at work, and receiving VIT, were re-stung during occupational activity. The grades of reaction developed under VIT treatment resulted clinically less severe than of those occurred at the first sting (p-value = 0.031). Conclusion. Our findings confirmed the clinical relevance of HVA, and described its occupational features in outdoor workers with sensitization, stressing the importance of an early identification and proper management of the professional categories recognized at high risk of hymenoptera stings. The Occupational Physician should be supported by other specialists to recommend appropriate diagnostic procedures and the prescription of VIT, which resulted an effective treatment for the prevention of episodes of severe reactions in workers with a proven HVA.

    Full Text Available Ankylosing spondylitis (AS is a chronic inflammatory disease, which typically begins in early decades of life with primarily axial joints involvement. This disease rarely affects patients older than 50 years of age. The aim of this study was to compare and evaluate the demographic, clinical, and laboratory features of late onset and early onset AS patients who were followed up in a single rheumatology center. A total of 339 patients who have been diagnosed with AS according to modified New York criteria were included in the study. The patients whose initial symptoms were observed after 50 years of age were accepted as late onset AS. Out of 339 patients, 27 (7.9% were diagnosed as late onset AS and 312 (92.3% patients were evaluated as early onset AS. Of 27 late onset patients, 10 were male and 17 were female. Delay in the diagnosis was 5.8 years for early onset AS, while it was 3.8 years for late onset AS (p = 0.001. Higher levels of acute phase reactants and more methotrexate (MTX use were detected in early onset AS patients compared to late onset AS (p = 0.001, p = 0.007, respectively. Statistically, there was no difference between these two groups, with regard to disease clinical activity indexes, anthropometric measurement parameters, uveitis and peripheral joint involvement. In this study, we showed that early and late onset AS patients may present with different clinical, genetic, and laboratory features. Late onset AS patients are characterized with lower human leukocyte antigen-B27 sequence, less inflammatory sign, delayed diagnosis, and less MTX and anti-tumor necrosis factor alpha drug usage.

    Smith-Magenis Syndrome (SMS) frequently goes unrecognized in newborns and infants as these patients do not yet demonstrate the characteristic behavioral phenotype and may only present with developmental delay and physical dysmorphism. Six of Hall`s ten cardinal features of trisomy 21 in the newborn are also frequently found in newborns with SMS, leading to an early presumptive diagnosis of DS in many of these patients. CASE No. 1: Based on clinical findings, a presumptive diagnosis of DS was given to the patient in the newborn period. Chromosome analysis of peripheral blood revealed a normal 46,XX karyotype. Given this result, the possibility of mosaic DS was raised, and a skin fibroblast study done. Again, the karyotype was reported as normal. Clinical features and cytogenetic analysis confirmed a diagnosis of SMS when the patient was 8 years old. CASE No. 2: A presumptive diagnosis of DS was made in an infant with hypotonia, facial dysmorphisms and congenital heart defects. A routine chromosome analysis was ordered, which revealed a 46,XY,del(17)(p11.2p11.2) karyotype. Indeed, approximately 38% of blood samples referred to our laboratory to rule out DS in an infant failed to demonstrate trisomy for chromosome 21. Given the high degree of clinical overlap with Down Syndrome, the diagnosis of SMS should be considered in all such patients. Additional analysis should be done to look for deletion 17p11.2 when faced with a {open_quotes}normal{close_quotes} karyotype in an infant referred to rule out DS.

    Full Text Available Background: Irritable bowel syndrome (IBS is classified into subtypes according to bowel habit. Objective: To investigate whether there are differences in clinical features, comorbidities, anxiety, depression and body mass index (BMI among IBS subtypes. Methods: The study group included 113 consecutive patients (mean age: 48 ± 11 years; females: 94 with the diagnosis of IBS. All of them answered a structured questionnaire for demographic and clinical data and underwent upper endoscopy. Anxiety and depression were assessed by the Hospital Anxiety and Depression scale (HAD. Results: The distribution of subtypes was: IBS-diarrhea (IBS-D, 46%; IBS-constipation (IBS-C, 32%, and mixed IBS (IBS-M, 22%. IBS overlap with gastroesophageal reflux disease (GERD, functional dyspepsia, chronic headache and fibromyalgia occurred in 65.5%, 48.7%, 40.7% and 22.1% of patients, respectively. Anxiety and/or depression were found in 81.5%. Comparisons among subgroups showed that bloating was significantly associated with IBS-M compared to IBS-D (odds ratio-OR-5.6. Straining was more likely to be reported by IBS-M (OR 15.3 and IBS-C (OR 12.0 compared to IBS-D patients, while urgency was associated with both IBS-M (OR 19.7 and IBS-D (OR 14.2 compared to IBS-C. In addition, IBS-M patients were more likely to present GERD than IBS-D (OR 6.7 and higher scores for anxiety than IBS-C patients (OR 1.2. BMI values did not differ between IBS-D and IBS-C. Conclusion: IBS-M is characterized by symptoms frequently reported by both IBS-C (straining and IBS-D (urgency, higher levels of anxiety, and high prevalence of comorbidities. These features should be considered in the clinical management of this subgroup.

    Salmonella is the most common etiological agent of cases and outbreaks of foodborne diarrheal illnesses. The emergence and spread of Salmonella spp., which has become multi-drug resistant and potentially more pathogenic, have increased the concern with this pathogen. In this study, 237 Salmonella spp., associated or not with foodborne salmonellosis in Brazil, belonging mainly to serotype Enteritidis, were tested for antimicrobial susceptibility and the presence of the virulence genes spvC, invA, sefA and pefA. Of the isolates, 46.8% were sensitive to all antimicrobials and 51.9% were resistant to at least one antimicrobial agent. Resistance to more than one antimicrobial agent was observed in 10.5% of the strains. The highest rates of resistance were observed for streptomycin (35.9%) and nalidixic acid (16.9%). No strain was resistant to cefoxitin, cephalothin, cefotaxime, amikacin, ciprofloxacin and imipenem. The invA gene was detected in all strains. Genes spvC and pefA were found in 48.1% and 44.3% of strains, respectively. The gene sefA was detected in 31.6% of the strains and only among S. Enteritidis. Resistance and virulence determinants were detected in Salmonella strains belonging to several serotypes. The high rates of antibiotic-resistance in strains isolated from poultry products demonstrate the potential risk associated with the consumption of these products and the need to ensure good food hygiene practices from farm to table to reduce the spread of pathogens relevant to public health.

    Full Text Available "nBrucellosis is not uncommon in children in endemic areas. We described clinical and laboratory features and therapeutic regimens for brucellosis in children under 14 who admitted in the Pediatric Medical Center Hospital, Tehran, Iran from March 1988 until February 2001. The male: female ratio was 2:1. Family history of brucellosis and consumption of un-pasteurized milk and dairy products was positive in 20.4% and 65.9%, respectively. The common clinical findings were arthritis (79.5%, fever (77.4%, anorexia (61.4%, sweating (52.3%, splenomegaly (43.2%, hepatomegaly (34.1% and lymphadenopathy (13.65. Anemia, leukopenia and thrombocytopenia were recorded in 56.8%, 31.8% and 9.1%, respectively. Out of all patients, seropositivity rate for brucellosis was found in 97.7% using serum agglutination test. Culture of blood and bone marrow specimen were positive in 30% and 50% of samples obtained, respectively. Rifampin and co-trimoxazole were the most commonly used combination in 68.1%. The overall relapse rate was 13.6%. Arthritis and fever were the most common clinical findings of brucellosis. Wright test is a very sensitive method to detect brucella infection. Public education and control measures should be applied to prevent the zoonotic and human brucellosis.

    Several works showed a decreased role for occlusion in the etiology of temporomandibular disorders (TMD). Nonetheless, it may be hypothesized that occlusion acts as a modulator through which bruxism activities may cause damage to the stomatognathic structures. To test this hypothesis, a logistic regression model was created with the inclusion of clinically diagnosed bruxism and eight occlusal features as potential predictors for temporomandibular joint (TMJ) pain in a sample of 276 consecutive TMD patients. The final logit showed that the percentage of the total log likelihood for TMJ pain explained by the significant factors was small and amounted to 13.2%, with unacceptable levels of sensitivity (16.4%). The parameters overbite > or = 4 mm combined with clinically diagnosed bruxism [OR (odds ratio) 4.62], overjet > or = 5 mm (OR 2.83), and asymmetrical molar relationship combined with clinically diagnosed bruxism (OR 2.77) were those with the highest odds for disease, even though none of those values was significant with respect to confidence intervals. Thus, the hypothesis under evaluation has to be rejected. It is possible that future studies with a higher discriminatory power for the different bruxism activities might be indicated to get deeper into the analysis of the potential mechanisms through which occlusion may play a role, even if small, in the etiology of the different TMD.

    Porphyria cutanea tarda is the most common disorder of porphyrin metabolism in the United States and Europe. This report presents the clinical, laboratory and pathologic features of 40 patients with porphyria cutanea tarda. Each patient was followed up for variable times during 1960-76 at the Clinical Research Center and the Dermatology Service of the Columbia-Presbyterian Medical Center; at the New York University Medical Center; or at the Rockefeller University Hospital. Earlier age at onset; diminution of alcohol ingestion as the major etiologic factor; and, an increased incidence in females indicate new environmental influences. The most frequently associated etiologic factor, aside from alcohol intake, was use of estrogens for contraception; postmenopausal syndrome; or treatment of prostatic carcinoma. Cutaneous findings in the patients included bullae (85%); increased skin fragility (75%); facial hypertrichosis (63%); hyperpigmentation (55%); sclerodermoid changes (18%); and, dystrophic calcification with ulceration (8%). Diabetes mellitus was found in 15%; systemic lupus erythematosus in 5%; elevated serum iron level in 62%; and, abnormal liver function test results in 60%. Histologic abnormalities were seen in liver biopsies of 34 patients. Phlebotomy is the treatment of choice. In 32 patients so treated, clinical remissions averaged 30.9 months. 31% (10 patients) had a relapse but additional phlebotomies resulted in 2nd remissions. Chloroquine and plasmaphoresis treatments were also briefly discussed.

    [Purpose] The purpose of this study was to determine the validity, demographic features of the newly developed Amer Dizziness Diagnostic Scale (ADDS), provide differential diagnosis of the vestibular disorders, assist in the clinical research and practice activities of health workers as well as to understand the probability of the utilization of the ADDS as a first-line evaluation tool in general clinical practice. [Subjects and Methods] Two hundred subjects of various ages including both male and female patients with a history of vertigo and/or dizziness were included in the study and evaluated once using the ADDS. [Results] There were more female (59.5%) than male (49.5) patients in this study. Additionally, we found that most patients (64.4%) had a central mediated problem. In addition, the Amer Dizziness Diagnostic Scale has been found to have both a sensitivity and specificity of 96% that can adequately determine the possible diagnosis of vestibular disorders. [Conclusion] This study has demonstrated the validity of the ADDS scale, the predominance of female involvement related to supplementary medication, vitamin D deficiency, general lifestyle factors, and fluid retention, high sensitivity and specificity, provide differential diagnosis of vestibular disorders that could be used as a first-line evaluation tool in general clinics.

    Localized scleroderma (LSc) primarily affects skin, whereas systemic sclerosis (SSc) affects skin and various internal organs. LSc and SSc are considered to be basically different diseases, and there is no transition between them. However, LSc and SSc have several common characteristics, including endothelial cell dysfunction, immune activation, and excess fibrosis of the skin, and there exist several SSc cases complicated with LSc during the course of SSc. Clinical and laboratory characteristics of SSc patients with LSc remain unclear. We investigated the clinical and laboratory features of 8 SSc patients with LSc among 220 SSc patients (3.6%). The types of LSc included plaque (5/8), guttate (2/8), and linear type (1/8). All cases were diagnosed as having SSc within 5 years before or after the appearance of LSc. In three cases of SSc with LSc (37.5%), LSc skin lesions preceded clinical symptoms of SSc. Young age, negative antinuclear antibody, and positive anti-RNA polymerase III antibody were significantly prevalent in SSc patients with LSc. The positivity of anticentromere antibody tended to be prevalent in SSc patients without LSc. No significant difference in the frequency of complications, such as interstitial lung disease, reflux esophagitis, and pulmonary artery hypertension, was observed. The awareness of these characteristic of SSc with LSc are essential to establish an early diagnosis and treatment.

    Objective:The aim of our study was to investigate the prognosis of obese breast cancer patients. Methods:This study was conducted on a total of 317 breast cancer patients who were histopathological y and clinical y diagnosed at the General Hospital of Shenyang Military Region (China) from 2004 to 2006. Clinical data including height, weight, age at diagnosis, tumor size, lymph node status, menopausal status, family history of cancer and hormone receptor status were col-lected. Log-rank test was performed to compare the disease free survival (DFS) and overal survival (OS). Cox proportional hazards regression analysis was conducted to make multivariate analysis. The Chi square test was used to compare the clinical features among normal weight group, overweight group, and obese group. Results:Obesity was an independent prognostic factor for DFS (P=0.022) and OS (P=0.032) in breast cancer patients. In the stratified analysis based on the hormone receptor status, obesity was independently associated with OS in patients with negative ER/PR (P=0.002), but such association was not observed in patients with positive hormone receptors. Obesity was also associated with lymph node status (P=0.001) and smoking (P=0.009). Conclusion:Obesity is associated with poor DFS and OS in patients with breast cancer. Therefore, maintaining normal weight may benefit breast cancer patients.

    Full Text Available Objective To summarize the clinical and pathological features of pyogenic liver abscess (PLA in patients with diabetes mellitus (DM. Methods A retrospective study was performed to analyze the clinical and pathological data of 42 DM patients with PLA in 306 Hospital of PLA from January 2001 to December 2010. Results All the DM patients with PLA were cured without relapse and mortality, and the hospital stay was 19-57 days. Thirty-three patients received minimally invasive surgical treatment, including 10 percutaneous needle aspiration (PNA, 23 percutaneous catheter drainage (PCD, and 3 patients undergoing surgical excision, with full and uneventful recovery. Among the 10 patients undergoing PNA, 6 patients were cured after one aspiration procedure, 3 patients after two, and 1 patient after three aspirations. The drainage tubes were removed from patients who received PCD after a mean of 8.6 days. 3-4 days after surgery, the temperature of patients returned to normal, and no complications occurred. The pathological examination revealed numerous fibrous septa in the abscess cavity, inflammatory cells infiltration in the liver tissues surrounding the abscess, and the presence of Mallory bodies in the cytoplasm. The examination also showed that the number of glycogen granule in the hepatocyte was decreased, and the expression of cytokeratin 8 increased (P<0.05. Conclusion  More attention should be paid to DM with the complication of PLA because of its particular clinical and pathological characteristics.

    Retention in early HIV care has been associated with virologic suppression and improved survival, but remains understudied in Brazil. We estimated retention in early HIV care for the period 2000-2013, and identified socio-demographic and clinical factors associated with good retention in an urban cohort from Rio de Janeiro, Brazil. Antiretroviral therapy-naïve, HIV-infected persons ≥18 years old linked to care between 2000 and 2011 were included. Retention in the first 2 years post-linkage (i.e. early care) was defined by the proportion of 6-month intervals with ≥1 HIV laboratory result. "Good" retention was defined as ≥1 HIV laboratory result recorded in at least three intervals. Overall, 80 % of participants met criteria for good retention and retention significantly improved over the study period. Older age, higher education level and early antiretroviral therapy initiation were associated with good retention. Efforts to improve retention in early care in this population should target younger and less-educated HIV-infected persons.

    BACKGROUND In high tuberculosis (TB) burden countries, there are few data on the performance of new molecular commercialised assays developed locally. OBJECTIVE To evaluate the performance of a new molecular commercialised assay for TB diagnosis (Detect-TB) in three laboratories. METHODS A total of 302 sputum samples from an equal number of patients with presumptive diagnosis of pulmonary tuberculosis (PTB) were submitted for routine smear microscopy, culture, and Detect-TB assay at three different sites in Brazil (the cities of Caxias do Sul, São Paulo and Canoas). FINDINGS Seventy four (24.7%) TB cases were diagnosed (65 bacteriologically confirmed). When compared to smear microscopy/culture results, the overall sensitivity and specificity of Detect-TB assay was 84.6% (CI 95%; 73.7-91.6) and 93.1% (CI 95%; 89.1-95.8), respectively. When compared to bacteriological and clinical diagnostic criteria, the sensitivity and specificity of Detect-TB assay was 74.3% (CI 95%; 63.3-82.9) and 92.9% (CI 95%; 88.7-95.6), respectively. Among the three sites - Caxias do Sul, São Paulo and Canoas - the sensitivity and specificity were respectively 94.7% and 97.8%; 71.4% and 93.9%, 82.1% and 88.9%. MAIN CONCLUSIONS These findings suggest that the Detect-TB assay could be applied routinely in reference laboratories across different regions in Brazil. PMID:28177043

    Full Text Available Abdominal angiostrongyliasis is a zoonotic infection caused by Angiostrongylus costaricensis, a nematode with an intra-vascular location in the mesentery. Our objective was to address several aspects of the natural history of this parasitosis, in a longitudinal clinical and seroepidemiological study. A total of 179 individuals living in a rural area with active transmission in southern Brazil were followed for five years (1995-1999 resulting in yearly prevalence of 28.2%, 4.2%, 10%, 20.2% and 2.8% and incidences of 0%, 5.9%, 8% and 1.5%, respectively. Both men and woman were affected with higher frequencies at age 30-49 years. In 32 individuals serum samples were collected at all time points and IgG antibody reactivity detected by ELISA was variable and usually persisting not longer than one year. Some individual antibody patterns were suggestive of re-infection. There was no association with occurrence of abdominal pain or of other enteroparasites and there was no individual with a confirmed (histopathologic diagnosis. Mollusks were found with infective third-stage larvae in some houses with an overall prevalence of 16% and a low parasitic burden. In conclusion, abdominal angiostrongyliasis in southern Brazil may be a frequent infection with low morbidity and a gradually decreasing serological reactivity.

    Full Text Available Abstract Background Many factors have been mentioned as contributing to under-diagnosis and under-reporting of zoonotic diseases particularly in the sub-Sahara African region. These include poor disease surveillance coverage, poor diagnostic capacity, the geographical distribution of those most affected and lack of clear strategies to address the plight of zoonotic diseases. The current study investigates the knowledge of medical practitioners of zoonotic diseases as a potential contributing factor to their under-diagnosis and hence under-reporting. Methods The study was designed as a cross-sectional survey. Semi-structured open-ended questionnaire was administered to medical practitioners to establish the knowledge of anthrax, rabies, brucellosis, trypanosomiasis, echinococcosis and bovine tuberculosis in selected health facilities within urban and rural settings in Tanzania between April and May 2005. Frequency data were analyzed using likelihood ratio chi-square in Minitab version 14 to compare practitioners' knowledge of transmission, clinical features and diagnosis of the zoonoses in the two settings. For each analysis, likelihood ratio chi-square p-value of less than 0.05 was considered to be significant. Fisher's exact test was used where expected results were less than five. Results Medical practitioners in rural health facilities had poor knowledge of transmission of sleeping sickness and clinical features of anthrax and rabies in humans compared to their urban counterparts. In both areas the practitioners had poor knowledge of how echinococcosis is transmitted to humans, clinical features of echinococcosis in humans, and diagnosis of bovine tuberculosis in humans. Conclusion Knowledge of medical practitioners of zoonotic diseases could be a contributing factor to their under-diagnosis and under-reporting in Tanzania. Refresher courses on zoonotic diseases should be conducted particularly to practitioners in rural areas. More emphasis

    Background Refractory anemia with ring sideroblasts associated with marked thrombocytosis was proposed as a provisional entity in the 2001 World Health Organization classification of myeloid neoplasms and also in the 2008 version, but its existence as a single entity is contested. We wish to define the clinical features of this rare myelodysplastic/myeloproliferative neoplasm and to compare its clinical outcome with that of refractory anemia with ring sideroblasts and essential thrombocythemia. Design and Methods We conducted a collaborative retrospective study across Europe. Our database included 200 patients diagnosed with refractory anemia with ring sideroblasts and marked thrombocytosis. For each of these patients, each patient diagnosed with refractory anemia with ring sideroblasts was matched for age and sex. At the same time, a cohort of 454 patients with essential thrombocythemia was used to compare outcomes of the two diseases. Results In patients with refractory anemia with ring sideroblasts and marked thrombocytosis, depending on the Janus Kinase 2 V617F mutational status (positive or negative) or platelet threshold (over or below 600×109/L), no difference in survival was noted. However, these patients had shorter overall survival and leukemia-free survival with a lower risk of thrombotic complications than did patients with essential thrombocythemia (P<0.001) but better survival (P<0.001) and a higher risk of thrombosis (P=0.039) than patients with refractory anemia with ring sideroblasts. Conclusions The clinical course of refractory anemia with ring sideroblasts and marked thrombocytosis is better than that of refractory anemia with ring sideroblasts and worse than that of essential thrombocythemia. The higher risk of thrombotic events in this disorder suggests that anti-platelet therapy might be considered in this subset of patients. From a clinical point of view, it appears to be important to consider refractory anemia with ring sideroblasts and

    Visceral leishmaniasis (VL) is an important health problem in Tunisia. It is most common in children under five years of age. The governorate of Kairouan (central Tunisia) is one of the most affected foci. The aim of this study was to update the epidemiological, clinical and biological features of the disease. The study concerned all VL cases admitted in the pediatric department of Kairouan hospital during 10 years (from 2004 to 2013). For every patient included in this study and when available, data such as sex, age, geographical origin and the condition of the patient at admission (clinical and biological findings) were collected. The myelogram results were also exploited as well as results of serology, culture, Real-Time polymerase chain reaction (PCR) and isoenzymatic typing of Leishmania isolates. Two hundred and forty cases were recorded. Rural cases (87.1%) were more prevalent than urban ones (12.9%). Age ranged from 2 months to 13 years (median, 18 months). The female/male sex ratio was 1.03. The diagnosis delays ranged from 1 day to 8 months (median, 15 days). The most common clinical symptoms at admission were splenomegaly (97.9%), fever (79.9%) and hepatomegaly (47.3%). The principal biological disturbances were anemia (91.7%), thrombocytopenia (83.9%) and leucopenia (56.1%). Among the different biological tools used for diagnosis confirmation, PCR was the most sensitive (100%). All 43 typed stocks corresponded to Leishmania (L.) infantum species. Although zymodeme MON-1 was predictably the most frequent (27 cases), L. infantum MON-24 and MON-80 were responsible of no negligible numbers of cases (11 and 5 cases respectively). The present study gave an updated epidemiological, clinical and biological profile of infantile VL in Tunisia. The diagnosis delays were considerably shortened compared to previous reports. However, an even earlier diagnosis of cases is needed to improve the disease prognosis. Real-Time PCR showed to be helpful in VL management.

    Full Text Available Abstract Background Coxsackievirus A9 (CA9 was one of the most prevalent serotype of enteroviral infections in Taiwan in 2011. After several patient series were reported in the 1960s and 1970s, few studies have focused on the clinical manifestations of CA9 infections. Our study explores and deepens the current understanding of CA9. Methods We analyzed the clinical presentations of 100 culture-proven CA9-infected patients in 2011 by reviewing their medical records and depicted the CA9 phylogenetic tree. Results Of the 100 patients with culture-proven CA9 infections, the mean (SD age was 4.6 (3.4 years and the male to female ratio was 1.9. For clinical manifestations, 96 patients (96% had fever and the mean (SD duration of fever was 5.9 (3.4 days. Sixty one patients (61% developed a skin rash, and the predominant pattern was a generalized non-itchy maculopapular rash without vesicular changes. While most patients showed injected throat, oral ulcers were found in only 19 cases (19%, among whom, 6 were diagnosed as herpangina. Complicated cases included: aseptic meningitis (n=8, bronchopneumonia (n=6, acute cerebellitis (n=1, and polio-like syndrome (n=1. Phylogenetic analysis for current CA9 strains is closest to the CA9 isolate 27-YN-2008 from the border area of mainland China and Myanmar. Conclusions The most common feature of CA9 during the 2011 epidemic in Taiwan is generalized febrile exanthema rather than herpangina or hand, foot, and mouth disease. Given that prolonged fever and some complications are possible, caution should be advised in assessing patients as well as in predicting the clinical course.

    Full Text Available Abstract Background Angiostrongylus vasorum infection is associated with high morbidity and mortality in dogs. Although recognised in Ireland, there are no large series of cases reported. The aim of this retrospective study was to identify pertinent clinical and geographical features in Irish dogs. Results The case records of dogs presenting to the University College Dublin Veterinary Hospital (1999-2010 were reviewed. A contemporaneous review of external faecal parasitology and post mortem submissions was also performed. A positive diagnosis of angiostrogylosis was identified in 49 dogs including 24 clinical, 10 post mortem and 15 external faecal sample cases. The majority (n = 44 (90% resided on the East Coast. In the clinical cases, the median age was 20 months, 29% of cases were older than 2 years. Clinical features included cardiorespiratory (63%, coagulopathic (71% and other (63% signs. Cough (n = 10, dyspnoea (n = 5 and tachypnoea (n = 3 were the most common cardiorespiratory abnormalities. Of animals with evidence of coagulopathy, excessive haemorrhage from a wound (n = 5, airway haemorrhage (n = 9, epistaxis (n = 3, haematoma (n = 4, suspected haemarthrosis (n = 3, neurological signs (n = 2 and haematuria (n = 1 were found. Ten dogs were anaemic, of which two were severe (haematocrit ≤ 0.20 L/L. Ten animals had thrombocytopenia, with four severely affected (≤50 × 109/L. PT and APTT values were prolonged in 4 (24% of 17 and a BMBT was prolonged in 5 (63% of 8 cases. Vague signs of exercise intolerance (n = 6, lethargy (n = 6 and weakness (n = 2 were identified, with two (8% animals having only these signs. In one animal the diagnosis appeared to be incidental. Thoracic radiographs (n = 19 identified abnormalities in 100% of cases. Four (17% animals died before or within 24 hours of treatment and post mortem examinations confirmed angiostrongylosis. Fenbendazole was administered in 19 cases, 18 (95% recovered. Two animals were

    AIM To describe the clinical features and microstructural characteristics assessed by in vivo confocal microscopy (IVCM) in patients with ocular cicatricial pemphigoid (OCP). METHODS A descriptive, uncontrolled case series study. Patients diagnosed with OCP were examined by clinical history, slit-lamp biomicroscopy features and IVCM images. The results of direct immunofluorescence (DIF) biopsies and indirect immunofluorescence (IIF) were also recorded. Local and systemic immunosuppressive therapy were administered and adjusted according to response. RESULTS A total of 12 consecutive OCP patients (7 male, 5 female; mean age 60.42±10.39y) were recruited. All patients exhibited bilateral progressive conjunctival scarring and recurrent chronic conjunctivitis was the most frequent clinical pattern. The mean duration of symptoms prior to diagnosis of OCP was 2.95±2.85y (range: 5mo to 10y). The Foster classification varied from stage I to IV and 20 eyes (83%) were within or greater than Foster stage III on presentation. Two of the 12 patients (17%) demonstrated positive DIF; 3 of the 12 (25%) patients reported positive IIF. The mean duration of the follow-up period was 20.17±11.88mo (range: 6 to 48mo). IVCM showed variable degrees of abnormality in the conjuctiva-cornea and conjuctival scarring was detected in all the involved eyes. Corneal s
