    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. 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. 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. This unexplained dermopathy was rare among this population of Northern California residents, but associated with significantly reduced health-related quality of life. No common underlying medical

    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.

    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. © 2010 American Academy of Forensic Sciences.

    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.

    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. PMID:25651321

    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.

    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.)

    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.

    Eccrine porocarcinoma is a rare, malignant cutaneous adnexal tumor that arises from the ducts of sweat glands. Found mainly in patients of advanced age, this tumor has diverse clinical presentations. Histology confirms the diagnosis, detects features relevant to prognosis, and guides treatment. Growth is slow, but the prognosis is poor if the tumor metastasizes to lymph nodes or visceral organs. We report 7 cases of eccrine porocarcinoma, describing patient characteristics, the clinical and histopathologic features of the tumors, and treatments used. Our observations were similar to those of other published case series. Given the lack of therapeutic algorithms or protocols for this carcinoma, we propose a decision-making schema based on our review of the literature and our experience with this case series. The algorithm centers on sentinel lymph node biopsy and histologic features. Copyright © 2016 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

    The aim of this study was to describe the imaging features of neuroendocrine differentiated breast carcinoma (NEDBC) and to correlate the radiological findings with the clinical and histopathological findings. A retrospective review of the mammograms of 1845 histopathologically proven breast cancer cases revealed five NEDBC. The clinical, imaging, and histopathological findings were analyzed. On mammography, a high-density mass was seen in all patients. The shape of the mass was round in 4 and irregular in 1 patient. The margins were spiculated in 2, indistinct in 1, microlobulated in 1, and partially obscured in 1 patient. On sonography, 4 patients had homogeneously hypoechoic masses with normal sound transmission. In 1 patient the mass was heterogeneously hypoechoic with mild posterior acoustic enhancement. The margins were microlobulated in 2, irregular in 2, and well-circumscribed in 1 patient. Neuroendocrine differentiated breast carcinoma should be included in the differential diagnosis of mammographically dense, round masses with predominantly spiculated or lobulated margins. Sonographically, they mostly present as irregular or microlobulated, homogeneously hypoechoic masses with normal sound transmission. (orig.)

    The limited form of Granulomatosis with Polyangiitis (GPA), formerly known as Wegener's Granulomatosis (WG) primarily involves the head and neck region, including the orbit, but is often a diagnostic challenge, particularly as it commonly lacks positive anti-neutrophil cytoplasm antibody (ANCA) titres or classical features on diagnostic orbital biopsies. The purpose of this study was to relate biopsy findings with clinical outcome and to determine which histopathological features are predictive of a clinical diagnosis of GPA. Retrospective case series of 234 patients identified from the database of the UCL Institute of Ophthalmology Department of Eye Pathology as having had orbital biopsies of orbital inflammatory disorders performed between 1988 and 2009. Clinical records were obtained for the patients and analysed to see whether patients had GPA or not, according to a standard set of diagnostic criteria (excluding any histopathological findings). Biopsy features were then correlated with the clinical diagnosis in univariate and multivariate analyses to determine factors predictive of GPA. Of the 234 patients, 36 were diagnosed with GPA and 198 with other orbital pathologies. The majority of biopsies were from orbital masses (47%). Histology showed a range of acute and chronic inflammatory pictures in all biopsies, but the presence of neutrophils (PGPA. In a multivariate analysis, only tissue neutrophils (OR=3.6, P=0.01) and vasculitis (OR=2.6, P=0.02) were independently associated with GPA, in contrast to previous reports associating eosinophils and necrosis with the diagnosis. Neutrophil, eosinophil and macrophage infiltration of orbital tissues, together with vasculitis and necrosis, are all associated with a clinical diagnosis of GPA, but only neutrophil infiltration and vasculitis are independently associated with this diagnosis. These features may assist in the establishing the diagnosis of limited GPA among patients with early orbital disease, particularly

    To determine the clinical, histopathologic and imaging features of pancreatic adenocarcinomas without secondary signs on dynamic CT. Seventy patients (mean age 70 years) with histologically proven pancreatic adenocarcinoma underwent preoperative contrast material-enhanced multiphasic multidetector CT before pancreatic resection. In each patient, clinical data including carbohydrate antigen 19-9, frequency of isoattenuating tumours, and presence of secondary signs and histopathologic findings such as tumour location, tumour stage, and microscopic infiltrative growth grade were evaluated. Ten tumours (14 %) were without secondary signs, and 60 (86 %) were with secondary signs. Tumours without and with secondary signs were located in the uncinate process in 5 (50 %) and 3 (5 %), head in 3 (30 %) and 29 (48 %), body in 2 (20 %) and 22 (37 %), and tail in 0 (0 %) and 6 (10 %), respectively (p =.001). The frequency of isoattenuating pancreatic adenocarcinomas without secondary signs was significantly higher than those with secondary signs (p = 0.034). The tumour stage of pancreatic adenocarcinomas without secondary signs was earlier than that in tumours with secondary signs (p = 0.041). Pancreatic adenocarcinomas without secondary signs is characterized by the presence of uncinate and isoattenuating tumours and earlier tumour stage compared to tumours with secondary signs. (orig.)

    We report clinical features and histopathological findings in fatal cases with dengue (DENV) and chikungunya (CHIKV) co-infection identified at the Colombian National Institute of Health between September 2014 and October 2015. Seven such cases were documented. Dengue serotype 2 virus was identified in six cases. All patients were adults and comorbidities were present in four. Fever, arthralgia or myalgia was present in all cases. The frequency of rash, haemorrhage, oedema, and gastrointestinal symptoms was variable. Laboratory findings such as thrombocytopenia, renal failure, and leukocyte count were also inconsistent between cases. Post-mortem tissue examination documented focal hepatocellular coagulative necrosis in three cases, incipient acute pericarditis in one and tubulointerstitial nephritis in one. This study provides evidence of mortality in patients with DENV and CHIKV co-infection. Fatal cases were characterised by variable clinical and laboratory features. Evaluation of histopathology of autopsy tissues provided evidence of the pathological consequences of the disease.

    Follicular variant papillary thyroid carcinoma (FVPTC) is the most common variant of papillary thyroid carcinoma (PTC) after classical PTC (CPTC). In this study, we aimed to compare functional status, ultrasonographical features, cytological results, and histopathological characteristics of patients with CPTC and FVPTC. Preoperative thyroid functions, thyroid autoantibodies, ultrasonographical features, cytology, and histopathology results of 354 (79.9%) CPTC and 90 (20.3%) FVPTC patients were reviewed retrospectively. Sex distribution, mean age, thyroid autoantibody positivity, and thyroid dysfunctions were similar in two groups. Among 320 patients with preoperative ultrasonography (US) findings, a hypoechoic halo was observed more frequently (p=0.003), and marginal irregularity was observed less commonly (p=0.024) in FVPTC lesions. In CPTC, rate of malignant cytology (p=0.001), and in FVPTC, rate of suspicious cytology (p<0.001) were significantly higher. Histopathologically, mean tumor diameter was markedly higher in FVPTC compared to CPTC (16.89 ± 13.86 vs 10.64 ± 9.70 mm, p<0.001), while capsular invasion and extrathyroidal spread were significantly lower in patients with FVPTC (p=0.018 and p=0.039, respectively). FVPTC tend to have more benign features in US and less malignant results in cytology. Higher tumor size in FVPTC might be explained by the recognition of clinical importance of these lesions after reaching particular sizes due to benign US features.

    Mastitis is a benign inflammatory process of the breast with heterogeneous histopathological findings, which clinically and radiographically may mimic a mammary carcinoma. We undertook a retrospective study on 37 cases of mastitis in our institution to correlate the radiographic imaging features and the clinical presentation with the histopathological findings. Histologically, there were 21 granulomatous, 7 fibrous, 3 plasma cell, 3 lupus, 2 lymphocytic, and 1 case of acute mastitis. Radiographically, 16/25 (64%) patients with ultrasound studies showed irregular hypoechoic masses suspicious for malignancy. Clinically, 38% of patients had an associated systemic disease. © 2015 Wiley Periodicals, Inc.

In this case we report a 24 yr-old male patient who presented to our dermatology department with diagnosed paucibacillary leprosy by his local dermatologist, and confirmed by perineurovascular lymphocytic infiltrate in the histopathological exam. On physical examination we found new plaque lesions that were suggestive of morphea with alteration of sensitivity. A new biopsy was performed showing sclerotic superficial dermis with thickening of the collagen bundles in deep dermis and linear arrays lymphocytic infiltrate between the collagen bundles that confirm the diagnosis of morphea.

    Tumor necrosis factor-α (TNF-α) inhibitors have been reported to induce new-onset psoriasis. To better define the demographic, clinical features, and treatment approach of TNF-α inhibitor-induced psoriasis. Systematic review of published cases of TNF-α inhibitor-induced psoriasis. We identified 88 articles with 216 cases of new-onset TNF-α inhibitor-induced psoriasis. The mean age at psoriasis onset was 38.5 years. The most common underlying diseases were Crohn disease (40.7%) and rheumatoid arthritis (37.0%). Patients underwent TNF-α therapy for an average of 14.0 months before psoriasis onset with 69.9% of patients experiencing onset within the first year. The majority of patients received skin-directed therapy, though patients who discontinued TNF therapy had the greatest resolution of symptoms (47.7%) compared with those who switched to a different TNF agent (36.7%) or continued therapy (32.9%). Retrospective review that relies on case reports and series. While TNF-α inhibitor cessation may result in resolution of induced psoriasis, lesions may persist. Decisions regarding treatment should be weighed against the treatability of TNF-α inhibitor-induced psoriasis, the severity of the background rheumatologic or gastrointestinal disease, and possible loss of efficacy with cessation followed by retreatment. Skin-directed therapy is a reasonable initial strategy except in severe cases. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

    2017-01-01

    Introduction Prevalence of ameloblastomas has been established worldwide but collective data of ameloblastoma in Southeast Asian countries has not been well analyzed. Aim Aim of this study was to report analysis and comparison of the prevalence and demographic data of clinical features of ameloblastoma and its histopathological variants in Southeast Myanmar and lower Northern Thailand populations. Materials and Methods A retrospective study on ameloblastoma was performed based on the availability of oral biopsy specimens in Faculty of Dentistry, Naresuan University, Phitsanulok, Thailand, between January 2002 and August 2015. The collected data were subjected to descriptive statistical analyses with the SPSS version 17.0 statistical software package (SPSS Inc., Chicago, USA). Pearson’s chi square (χ2) test and t-test were employed. The critical level of significance was set at pameloblastoma with male:female ratio of 1.14:1. The mean age of the patients was 31.3±15.6 years. The predominance anatomical distribution was observed in the mandible (86.7%). Posterior body-ramus-angle region was the most common site. Almost all cases were asyptomatic and most common clinical manifestation was swelling of affected region. Multilocular radiolucency was observed in 70% of cases, whereas 30% were unilocular. Three subtypes of ameloblastomas were diagnosed: unicystic ameloblastoma (20%), conventional solid/multicystic ameloblastoma (70%), and desmoplastic ameloblastoma (10%). The most common histologic pattern was the plexiform type (57.2%) followed by follicular type (23.8%). Conclusion Prevalence of ameloblastoma in Southeast Myanmar and lower Northern Thailand populations correspond with data from other geographic areas of Thailand and other Asian countries. However, some demographic and histopathological profiles are different, with plexiform ameloblastoma being the most common subtype in this study. PMID:28274056

    Full Text Available Ovarian steroid cell tumours (not otherwise specified are rare neoplasms of the ovary and are classified under lipid cell tumours. Their diagnosis can be considered as one of exclusion. Histopathologically, the tumour should carefully be evaluated for microscopic features of malignancy, but it is essential for the clinician and the pathologist to remember that in these tumours, pathologically benign histomorphology does not exclude the possibility of clinically malignant behaviour. Our case study focuses on the comparative findings in a postmenopausal female diagnosed with an ovarian steroid tumour (not otherwise specified. A careful correlation between clinical and surgical evaluation and microscopic analysis is necessary, as is a regular followup.

    Full Text Available A 2-year-old, intact male Siberian Husky was presented with corneal opacity, eye lid swelling, depigmentation, alopecia and erythema predominantly on face. Bilateral uveitis preceded periocular and nasal planum depigmentation. Ancillary tests excluded other systemic diseases. Histopathology of the skin revealed lichenoid interface dermatitis with pigmentary incontinence. Diffuse pyogranulomatous inflammation of the globes was also noted. Based on the clinical signs and characteristic histopathological findings, the dog was diagnosed as uveodermatologic syndrome (UDS. Further treatment was not attempted in this case and the dog was euthanized. This case report describes typical clinical and histopathologic features of UDS in a Siberian Husky.

    Twenty-three cases of ovarian fibroma, comprising 3% of all benign tumors seen over a 20-year period, were analyzed. It was unilateral in all cases affecting more commonly the left ovary (70%). Whilst a majority of cases (77%) were encountered in the reproductive age group, the tumor was rare before the second decade. Only in 13% of cases was ascitis clinically detectable. This was not influenced by the size and weight (average of 9.3 x 10.8 x 11.1 cm and 959 g, respectively) of the tumors; a smooth-surfaced tumor was, however, associated with a greater amount of peritoneal fluid. Varying degrees of calcification in some tumors are detectable on ultrasonography and occasionally on abdominal radiography. The classical Meig's Syndrome was seldom encountered. The histopathological features, diagnostic problems and management are discussed.

    Histopathologic features, particularly Gleason grading system, have contributed significantly to the diagnosis, treatment, and prognosis of prostate cancer for decades. However, prostate cancer demonstrates enormous heterogeneity in biological behavior, thus establishing improved prognostic and predictive markers is particularly important to personalize therapy of men with clinically localized and newly diagnosed malignancy. Many automated grading systems have been developed for Gleason grading but acceptance in the medical community has been lacking due to poor interpretability. To overcome this problem, we developed a set of visually meaningful features to differentiate between low- and high-grade prostate cancer. The visually meaningful feature set consists of luminal and architectural features. For luminal features, we compute: 1) the shortest path from the nuclei to their closest luminal spaces; 2) ratio of the epithelial nuclei to the total number of nuclei. A nucleus is considered an epithelial nucleus if the shortest path between it and the luminal space does not contain any other nucleus; 3) average shortest distance of all nuclei to their closest luminal spaces. For architectural features, we compute directional changes in stroma and nuclei using directional filter banks. These features are utilized to create two subspaces; one for prostate images histopathologically assessed as low grade and the other for high grade. The grade associated with a subspace, which results in the minimum reconstruction error is considered as the prediction for the test image. For training, we utilized 43 regions of interest (ROI) images, which were extracted from 25 prostate whole slide images of The Cancer Genome Atlas (TCGA) database. For testing, we utilized an independent dataset of 88 ROIs extracted from 30 prostate whole slide images. The method resulted in 93.0% and 97.6% training and testing accuracies, respectively, for the spectrum of cases considered. The

    Full Text Available Background: Intrathyroid lymphoid tissue is accrued in Hashimoto thyroiditis (HT. Histologically, this acquired lymphoid tissue bears a close resemblance to mucosa-associated lymphoid tissue (MALT and can evolve to lymphoma. Aim: To demonstrate the morphological, and immunohistochemical profiles of Hashimoto thyroiditis and to ascertain the importance of light chain restriction in distinguishing HT with extensive lymphoplasmacytoid infiltrate from MALT lymphoma. Materials and Methods: We studied histopathologically and immunohistochemically (CD20, CD3, Igk, Igl and cytokeratin 30 cases of HT for evaluation of the lymphoid infiltrate and the presence of lymphoepithelial lesions (LELs. Distinguishing between early thyroid lymphoma and HT was evaluated by light chain restriction. These findings were compared with two cases of primary thyroid lymphoma. Results: The histopathological findings were characteristic of HT. Immunohistochemistry confirmed inconspicuous, rare B-cell LELs as well as a prominent T-lymphocyte population. Testing for light chain restriction showed polyclonal population of plasma cells. The cases of MALT lymphoma had distinct destructive lymphoepithelial lesions, B-cell immunophenotyping and showed kappa light chain restriction in the plasmacytoid population. Conclusions: Hashimoto thyroiditis differs both histopathologically and immunohistochemically from thyroid lymphoma. In suspicious cases, immunohistochemistry could be helpful in reaching a definitive diagnosis.

    Full Text Available Acanthamoeba keratitis, infectious crystalline keratopathy and atypical mycobacterial keratitis have recently emerged as important types of infectious keratitis. These corneal infections have been associated with contact lens wear and with corneal surgical procedures such as radial keratotomy and penetrating keratoplasty, and the clinical setting of each of these infections is important in alerting the clinician to the possible diagnosis. There have been improvements in rapid diagnostic techniques for such infections in the last several years. Treatment has also improved, but remains a difficult problem, especially for Acanthamoeba. An overview of recent developments in the clinical and histopathologic methods for diagnosis and treatment options of these three corneal infections is provided.

    Objective To study the clinical characteristics and histopathologic features of partially involuting congenital hemangiomas (PICH). Methods The clinical and histopathologic data of 7 RICH patients were reviewed retrospectively and compared to the non-involuting congenital hemangioma (NICH) and rapidly involuting congenital hemangioma (RICH). Results Two male and five female healthy infants presented with a vascular tumor involving the extremity (n=5) and trunk (n=3) at birth. The mass was round to ovoid in shape, bossed and solid, pink to purple and surrounded by a pale halo. Size of tumor was over 5.0 cm in diameter (greatest dimension) in all patients. All had rapid involution during the first 7 to 48 weeks (mean 28 weeks) of life before stabilizing in size and appearance. The overlying skin was frequently punctuated by coarse telangiectasia and surrounded by a pale halo. Doppler ultrasound imaging demonstrated hypervascular subcutaneous lesions with low-resistance, high-velocity arterial flow. MRI: the T1-weighted magnetic image showed subcutaneous lesions with uniform signal intensity and the T2-weighted magnetic image showed homogeneously increased signal intensity. T1-weighted magnetic image after gadolinium revealed an intense and homogeneous enhancement with well-defined limits. HE staining:the architecture in most specimens was dominated by lobules of capillaries in the dermis and subcutis that were separated by dense fibrous tissue. The lobules were composed of thin-walled capillaries, usually with round lumina in various size. The endothelial cells were moderately plump and had a dark, round, protruding nucleus. The nucleus/cytoplasm ratio increased, but there was no obviously atypical and the mitoses was rarely seen. The "hobnailed" endothelial cells lined the small intralobular vessels were observed in all specimens. Immunostaining for CD31 and CD34 demonstrated strong expression in lobular and extralobular endothelial cells. Endothelial cells were

    In histopathological image analysis, feature extraction for classification is a challenging task due to the diversity of histology features suitable for each problem as well as presence of rich geometrical structures. In this paper, we propose an automatic feature discovery framework via learning class-specific dictionaries and present a low-complexity method for classification and disease grading in histopathology. Essentially, our Discriminative Feature-oriented Dictionary Learning (DFDL) method learns class-specific dictionaries such that under a sparsity constraint, the learned dictionaries allow representing a new image sample parsimoniously via the dictionary corresponding to the class identity of the sample. At the same time, the dictionary is designed to be poorly capable of representing samples from other classes. Experiments on three challenging real-world image databases: 1) histopathological images of intraductal breast lesions, 2) mammalian kidney, lung and spleen images provided by the Animal Diagnostics Lab (ADL) at Pennsylvania State University, and 3) brain tumor images from The Cancer Genome Atlas (TCGA) database, reveal the merits of our proposal over state-of-the-art alternatives. Moreover, we demonstrate that DFDL exhibits a more graceful decay in classification accuracy against the number of training images which is highly desirable in practice where generous training is often not available.

    Background Pheochromocytomas are tumors arising from chromaffin tissue located in the adrenal medulla associated with typical symptoms and signs which may occasionally develop metastases, which are defined as the presence of tumor cells at sites where these cells are not found. This retrospective analysis was focused on clinical, genetic, and histopathologic characteristics of primary metastatic versus primary benign pheochromocytomas. Materials and methods We identified 41 subjects with metastatic pheochromocytoma and 108 subjects with apparently benign pheochromocytoma. We assessed dimension and biochemical profile of the primary tumor, age at presentation, and time to develop metastases. Results Subjects with metastatic pheochromocytoma presented at a significantly younger age (41.4±14.7 vs. 50.2±13.7 years; Ppheochromocytomas. No significant differences were found in the incidence of genetic mutations in both groups of subjects (25.7 % in the metastatic group and 14.7 % in the benign group; P=0.13). From available histopathologic markers of potential malignancy, only necrosis occurred more frequently in subjects with metastatic pheochromocytoma (27.6 % vs. 0 %; Ppheochromocytoma and age of its first presentation are two independent risk factors associated with the development of metastatic disease.

    Osteoporosis is one of the most common disorders in postmenopausal women, affecting the quality of life and increasing the risk for fractures in minor traumas. Changes in the bone microarchitecture causes static changes in the body and affects motility. In this study, we analyzed two groups of women, one with physiological menopause and one with surgically induced menopause. The diagnosis of osteoporosis was suspected based on the clinical symptoms and confirmed by assessing bone mineral density by the dual-energy X-ray absorptiometry (DEXA). Comparing some clinical and biological aspects there was noted that a much higher percentage of women with surgically induced menopause exhibited increases in body mass index, changes in serum lipids, cholesterol, triglycerides, blood glucose, serum calcium, magnesemia and osteocalcin. In contrast, no significant differences were observed in the histopathological aspects of bone tissue examined from these two groups. In all patients, there was identified a significant reduction in the number of osteocytes and osteoblasts, the expansion of haversian channels, reducing the number of trabecular bone in the cancellous bone with wide areola cavities often full of adipose tissue, non-homogenous demineralization of both the compact bone and the cancellous bone, atrophy and even absence of the endosteal, and the presence of multiple microfractures. Our study showed that early surgically induced menopause more intensely alters the lipid, carbohydrate and mineral metabolism, thus favoring the onset of osteoporosis.

    Central core disease (CCD) is a congenital myopathy characterized by distinctive cores in muscle fibers. Mutations in the gene encoding ryanodine receptor 1 (RYR1) have been identified in most CCD patients. Two unrelated patients presented with slowly progressive or nonprogressive proximal muscle weakness since childhood. Their family history revealed some members with the same clinical problem. Histological analysis of muscle biopsy samples revealed numerous peripheral cores in the muscle fibers. RYR1 sequence analysis disclosed a novel mutation in exon 101 (c.14590T>C) and confirmed a previously reported mutation in exon 102 (c.14678G>A). We report herein two families with CCD in whom missense mutations at the C-terminal of RYR1 were identified. Although it has been accepted that such mutations are usually associated with a severe clinical phenotype and clearly demarcated central cores, our patients exhibited a mild clinical phenotype without facial muscle involvement and skeletal deformities, and atypical cores in their muscle biopsy specimens.

    Pathologists are required to integrate data from multiple sources when making a diagnosis. Furthermore, whole slide imaging (WSI) and next generation sequencing will escalate data size and complexity. Development of well-designed databases that can allow efficient navigation between multiple data types is necessary for both clinical and research purposes. We developed and evaluated an interactive, web-based database that integrates clinical, histologic, immunohistochemical and genetic information to aid in pathologic diagnosis and interpretation with nine lung adenocarcinoma cases. To minimize sectioning artifacts, representative blocks were serially sectioned using automated tissue sectioning (Kurabo Industries, Osaka Japan) and selected slides were stained by multiple techniques, (hematoxylin and eosin [H&E], immunohistochemistry [IHC] or fluorescence in situ hybridization [FISH]). Slides were digitized by WSI scanners. An interactive relational database was designed based on a list of proposed fields covering a variety of clinical, pathologic and molecular parameters. By focusing on the three main tasks of 1.) efficient management of textual information, 2.) effective viewing of all varieties of stained whole slide images (WSI), and 3.) assistance in evaluating WSI with computer-aided diagnosis, this database prototype shows great promise for multi-modality research and diagnosis. © 2016 Japanese Society of Pathology and John Wiley & Sons Australia, Ltd.

    Capillaria hepatica is a nematode parasite of wild rodents and other mammals. Adult worms inhabit the liver. Recently, during the necropsy examination of a group of 160 rabbits from a commercial supplier, firm pale or cystic areas (1-5 mm) were noted on the liver in thirteen animals. On further investigation, these animals were found to be infected with C. hepatica. The histopathological features of the infection in the rabbit are described for the first time and diagnostic features recorded. Lesions were identified predominantly in portal tracts consisting of dilated bile ducts with luminal debris, peribiliary inflammatory cell infiltrates, and fibrosis. Large granulomas (macrogranulomas) were evident in portal areas and involved the bile ducts. Macrogranulomas contained collections of characteristic C. hepatica eggs, macrophages, eosinophils, and lymphocytes. Small granulomas (microgranulomas), characterized by epithelioid macrophages surrounded by lymphocytes and eosinophils, were also identified. C. hepatica eggs were also observed in the lumina of the bile ducts and gall bladder. No adult C. hepatica worms were identified. Oocysts of Eimeria stiedae were also evident in the biliary epithelium in some animals. The unique characteristics of the C. hepatica life cycle are described, and the differential diagnosis of hepatic capillariasis is discussed.

    Equine odontoclastic tooth resorption and hypercementosis (EOTRH) is a painful progressive condition of older horses that involves multiple teeth, including canines and incisors. EOTRH is uncommonly recognized by veterinary pathologists and in some cases may be misdiagnosed as cementoblastoma. The cause is unknown. The goals of this study were to describe the histopathologic features of EOTRH in 17 affected horses from the United States and to increase awareness of this condition. Samples ranged from affected tooth to the entire rostral mandible and maxilla. Affected teeth exhibited cemental hyperplasia and lysis. The marked proliferation of cementum in severe cases caused bulbous enlargement of the intra-alveolar portions of affected teeth. Several teeth contained necrotic debris, bacteria, and plant material in the regions of cemental lysis. All horses exhibited dentinal lysis in at least affected tooth, and several contained necrotic debris in these regions. Endodontic disease was often present with inflammation, lysis, necrotic debris, fibrosis, and/or a thin rim of atubular mineralized tissue in the pulp cavity. Periodontal disease was a common feature that was primarily characterized by moderate lymphoplasmacytic inflammation. Resorption with secondary hypercementosis appears to begin on the external surface of the teeth rather than within the pulp cavity. Distinguishing EOTRH from other diseases requires a complete history that includes the number and location of affected teeth, a gross description of regional hard/soft tissue health, and radiographic findings.

    Full Text Available Abstract Background Coats' disease is a non-hereditary ocular disease, with no systemic manifestation, first described by Coats in 1908. It occurs more commonly in children and has a clear male predominance. Most patients present clinically with unilateral decreased vision, strabismus or leukocoria. The most important differential diagnosis is unilateral retinoblastoma, which occurs in the same age group and has some overlapping clinical manifestations. Case presentation A 4 year-old girl presented with a blind and painful right eye. Ocular examination revealed neovascular glaucoma, cataract and posterior synechiae. Although viewing of the fundus was impossible, computed tomography disclosed total exsudative retinal detachment in the affected eye. The eye was enucleated and subsequent histopathological evaluation confirmed the diagnosis of Coats' disease. Conclusion General pathologists usually do not have the opportunity to receive and study specimens from patients with Coats' disease. Coats' disease is one of the most important differential diagnoses of retinoblastoma. Therefore, It is crucial for the pathologist to be familiar with the histopathological features of the former, and distinguish it from the latter.

    Full Text Available Background: Clinical-histopathological data contributes to a better diagnosis, assessment and treatment of head and neck lesions. Objective: To determine clinical-histopathological correlation of head and neck lesions. Methods: a descriptive, retrospective, observational study was developed in a series of cases (360 patients to determine the clinical diagnostic scope in relation to the histopathological techniques used in the Maxillary Surgery Service of “Gustavo Aldereguía Lima” hospital between June 2006 and 2007. Required data was taken from clinical histories and records from Pathological Anatomy, which were transferred to a form design for that purpose. Results: The age group of 0-19 years had the higher concordance among the studied groups (72,4%. 59, 7% of the studied cases had clinical-histopathological concordance, mainly in extra-oral lesions (60, 4% particularly in the vermilion border (82, 4 % and among the intra-oral the most common were those in the vestibular duct (100%. The most important lesions where clinical diagnosis did not coincide with histopathological diagnosis were fibroma with 23 in the intra-oral and warts and a total of 34 in extra-oral, followed by basal carcinomas. Conclusions: There is a significant correlation between clinical and histopathological diagnosis, suggesting high attention quality and correct application of the clinical method as central element in patients’ management.

    The purpose of this study was to identify histopathologic correlates for the varied appearances of breast masses on contrast-enhanced ultrasonography (CEUS). Contrast-enhanced ultrasonography was performed in 104 patients (age range, 19-86 years) after administration of a sulfur hexafluoride microbubble contrast agent, and enhancement patterns were classified as no enhancement, peripheral enhancement, homogeneous enhancement, regional enhancement, and heterogeneous enhancement. All patients' histologic slides were reviewed and correlated with CEUS findings. In malignant masses, heterogeneous enhancement corresponded to tumor cell cords or clusters in a variable amount of desmoplastic stroma. Homogeneous enhancement corresponded to hypercellularity in the whole mass, or ductal carcinoma in situ (DCIS) was predominant. Regional enhancement corresponded to a DCIS component. Peripheral enhancement corresponded to a DCIS component, hypercellularity or adenosis at the periphery, and low-degree cellularity, degeneration, fibrosis, or necrosis in the center. No enhancement was present in 1 case of low-grade DCIS. In benign masses, heterogeneous enhancement corresponded to loose cell proliferation in a more sclerotic stroma. Homogeneous enhancement corresponded to diffuse hypercellularity, an inflammatory cell infiltrate, or intraductal papilloma. Regional enhancement corresponded to focal hypercellularity or intraductal papilloma within a dilated duct. No enhancement corresponded to desmoplastic stroma. Peripheral enhancement was shown in 1 case of granulomatous mastitis with an inflammatory infiltrate at the periphery and necrosis in the center. Breast mass CEUS findings correlated with histologic features.

    To describe the ultrasound, histopathological and genetic characteristics of uveal melanoma in a Mexican-Mestizo population. A total of 39 enucleated eyes with a histopathological diagnosis of uveal melanoma were assessed by describing the clinical findings, and ultrasound, histopathological and genetic features. A high correlation was observed between tumour height measurement using ultrasound and histopathology. In our cases, tumour size and reflectivity were higher compared with those reported in the literature. The preliminary data on the molecular assessment of the tumours show the presence of an unreported polymorphism (T>C IVS5+34) and one sample with GNAQ mutation (A>C CAA>CCA Gln 209 Pro). Ultrasound is a reliable method to identify the size of the tumour. Furthermore, knowledge of the molecular mechanisms promises new perspectives for the development of new targeted therapeutics. Fortunately this leads to progress in the treatment of patients with metastatic disease or prevents it in those at high risk. Copyright © 2017 Sociedad Española de Oftalmología.

    Full Text Available Background and Design: Dermoscopy has an important role in the diagnosis of melanoma nowadays. Dermoscopic findings of melanoma had been associated with Breslow thickness and invasion status in previous studies but the relationship between dermatoscopic findings and other histopathological prognostic indicators has not been investigated until today. In this study, our aim is to investigate the relationship between dermatoscopic findings and histopathologic prognostic indicators such as Breslow thickness, invasion status, mitotic rate, lymphovascular invasion (LVI, ulceration and regression in patients who had been diagnosed with melanoma due to their clinical, dermatoscopic and histopatological findings. Materials and Methods: Dermoscopic and histopathological findings of 47 cases of melanoma who applied to our clinic between the years 2000 and 2014 were evaluated. The relationship between the dermoscopic findings which had been reported to be observed in melanomas in previous research and the histopathologic prognostic indicators such as Breslow thickness, invasion status, mitotic rate, lymphovascular invasion, ulceration and regression were investigated. Results: Irregular dots/globules, atypical pigment network, multifocal hypopigmentation, radial streaks and moth-eaten borders have been associated with good prognostic indicators whereas comedo like openings, regular blotch, exophytic papillary structures, dotted, glomerular, lineer irregular vessels, pink/red and blue/gray colors were associated with poor prognostic indicators. Additionally some dermatoscopic findings which are more observed in benign lesions such as multiple milia-like cysts, comedo like openings, moth-eaten borders, regular blotch, exophytic papillary structures and finger print areas have been observed in melanomas in our study. Conclusion: Many dermoscopic findings have demonstrated statistically significant association with the histopathological prognostic indicators

    Recently, with the advent of the 7th edition of the AJCC Cancer Staging manual, at least one set of criteria (e.g. breast) were modified to now require the measurement of maximal depth of stromal invasion. With the current manual interpretive morphological approaches typically employed by surgical pathologists to assess tumor extent, the specialty now potentially has stumbled upon a crossroads of practice, where the diagnostic criteria have exceeded the capabilities of our commonly available tools. While whole slide imaging (WSI) technology holds the potential to offer many improvements in clinical workflow over conventional slide microscopy including unambiguous utility for facilitating quantitative diagnostic tasks with one important example being the determination of both linear dimension and surface area. However, the availability of histology data in digital form is of little utility if time-consuming and cumbersome manual workflow steps are necessarily imposed upon the pathologist in order to generate such measurements, especially as encountered with the complex and ill-defined shapes inherent to infiltrative tumors. In this communication, we demonstrate the utility of the recently described SIVQ algorithm to serve as the basis of a highly accurate, precise and semi-automated tool for direct surface area measurement of tumor infiltration from WSI data sets. By anticipating the current trend in cancer staging that emphasizes increasingly precise feature characterization, as witnessed by the recent publication of AJCC's 7th edition of the Cancer Staging Manual, this tool holds promise to will be of value to pathologists for clinical utility.

    Programmed cell death protein 1 (PD-1) blocking agents are novel immunotherapeutics used for treatment of advanced-stage malignancies. They have shown promise in the treatment of several malignancies, with greater efficacy and better tolerability than cytotoxic T-lymphocyte antigen 4 (CTLA-4) blocking agents. However, as with anti-CTLA-4 agents, clinically significant colitis remains an important complication. Although there is growing awareness of the histopathologic features of anti-CTLA-4 therapy, there is little information on the pathologic features of anti-PD-1 colitis. We describe here the histopathologic findings in 8 patients who developed colitis while on anti-PD-1 monotherapy. The most common pattern of injury observed (5/8 cases) was an active colitis with neutrophilic crypt microabscesses and with prominent crypt epithelial cell apoptosis and crypt atrophy/dropout. These latter features are reminiscent of other colitides with prominent apoptosis such as acute graft-versus-host disease or certain drug-induced colitides. The remainder of cases (3/8) showed a lymphocytic colitis-like pattern, characterized by increased intraepithelial lymphocytes and surface epithelial injury. Apoptosis was also often increased in these cases but crypt atrophy/dropout was not present. In patients who experienced recurrence of anti-PD-1 colitis, histologic features were similar to the initial insult but, in addition, features of chronicity developed that mimicked inflammatory bowel disease (basal lymphoplasmacytosis and crypt architectural irregularity, and Paneth cell metaplasia in 1 case). Awareness of the clinical scenario, however, should allow pathologists to suggest anti-PD-1 colitis. Interestingly, recurrent colitis was observed in patients who had been off anti-PD-1 therapy for many months. As anti-PD-1 agents are increasingly used in oncology, we present this series to increase awareness of anti-PD-1 colitis among pathologists, to facilitate its timely diagnosis

    A form of Hashimoto's thyroiditis with lymphoplasmacytic sclerosing changes and increased numbers of IgG4-positive plasma cells has recently been reported in the literature. These histopathological features suggest that this subtype of Hashimoto's thyroiditis may be closely related to IgG4-related disease. Therefore, this unique form of IgG4-related Hashimoto's thyroiditis, which is referred to as IgG4 thyroiditis, has its own clinical, serological, and sonographic features that are distinct from those associated with non-IgG4 thyroiditis. IgG4 thyroiditis shares similarities with the well-known fibrous variant of Hashimoto's thyroiditis; however, the detailed histopathological features of IgG4 thyroiditis have not been well established. Based on immunostaining results, 105 patients with Hashimoto's thyroiditis were divided into an IgG4 thyroiditis group (n=28) and a non-IgG4 thyroiditis group (n=77). As in our previous reports, IgG4 thyroiditis was associated with a patient population of a younger age, a lower female-to-male ratio, rapid progression, higher levels of thyroid autoantibodies, subclinical hypothyroidism, and diffuse sonographic echogenicity. Histopathologically, this group revealed severe lymphoplasmacytic infiltration, dense stromal fibrosis, marked follicular cell degeneration, numerous micro-follicles, and notable giant cell/histiocyte infiltration. Importantly, the IgG4-related group did not completely overlap with fibrous variant of Hashimoto's thyroiditis. Four cases (14%) in the IgG4 thyroiditis group presented only mild fibrosis in the stroma, whereas 29 cases (38%) in the non-IgG4 thyroiditis group met the diagnostic criteria for fibrous variant of Hashimoto's thyroiditis. Furthermore, we observed three patterns of stromal fibrosis in Hashimoto's thyroiditis: interfollicular fibrosis, interlobular fibrosis, and scar fibrosis. The IgG4 thyroiditis group was significantly associated with the presence of predominant interfollicular fibrosis. In

    Full Text Available Purpose. The aim of this study is to investigate the etiology and the clinical, microbiological, histopathological, and radiological findings of acquired dacryocystoceles. Methods. In this retrospective study, we reviewed the clinical records of 10 eyes of 8 patients with dacryocystoceles who underwent external dacryocystorhinostomy (DCR surgery. Etiology, presenting symptoms and radiological findings as well as microbiological and histopathological assessment results and outcome were analyzed. Results. The records of 8 patients with dacryocystoceles were included in this study. In the histopathological evaluations of the samples collected from the lacrimal sac wall, chronic inflammation was found in all biopsied samples and fibrosis was observed in two histopathological evaluations. Computerized tomography (CT imaging showed fluid collection separated from adjacent tissues by a thin rim, corresponding to dacryocystoceles in the sac. In the microbiological culture examination of samples collected from the fluid within the cyst, no bacterial growth in 5 eyes, gram-negative bacillus growth in 3 eyes, and gram-positive cocci growth in 2 eyes were found. Conclusions. Acquired dacryocystoceles were observed extremely rarely and a definite pathogenic agent could not be identified in any of the cases, either microbiologically or histologically, whereas chronic inflammation was detected in all cases in our study.

    Equine pastern vasculitis is clinically challenging and the underlying aetiopathogenesis is unclear. The aims of this retrospective study were to establish histopathological criteria for pastern vasculitis, to look for an underlying cause, to investigate whether the histopathological lesions are associated with a distinct clinical picture, to assess if and how the clinical picture varies, and to determine the treatment response. Skin biopsies and clinical data from 20 horses with a diagnosis of vasculitis of the distal extremities were investigated and histology was compared to biopsies from healthy horses. It was concluded that intramural inflammatory cells, leukocytoclasia with nuclear dust, thickening and oedema of the vessel walls, and microhaemorrhages are highly specific histological findings in equine pastern vasculitis. Based on the feedback from the clinicians, the lesions were mostly seen on the lateral and medial aspects of un-pigmented legs. Lesions in white skin were characterised by exudation and crusts, whereas those in pigmented skin were alopecic and characterised by scaling. The response to treatment was poor and the prognosis guarded. No association was found between any of the histopathological findings and a distinct clinical picture. An underlying cause of equine pastern vasculitis could not be identified. Considering the large number of confounding factors, the causative agents are difficult to identify, but may involve drugs or a hypersensitivity reactions to yet unknown antigens.

    Full Text Available This manuscript describes the clinical and pathological findings associated with a unilateral horn core carcinoma in a 12- year-old, Nellore cow. Initially the cow presented a small growth within the right horn with consequent hanging of the affected horn and progressive increasein size of the mass, ultimately resulting in a large space occupying tumorous growth. Clinical laboratory evaluations revealed non-regenerative anemia; while bacteriological analyses yielded cultures of Pseudomonnas spp. and Arcanobacterium spp. Histopathology revealed the mass to be consisted predominantly of a well differentiated squamous cell carcinoma with areas of neoplastic glandular epithelium. The anatomic location of the tumor associated with the histopathological findings is consistent with horn core carcinoma of cattle.Este manuscrito descreve os achados clínicos e patológicos associados com um carcinoma da base do chifre de uma vaca da raça Nelore de 12 anos de idade. Inicialmente a vaca apresentou uma pequena massa dentro do seio do corno direito com aumento progressivo no tamanho, que se evidenciou após a fratura do mesmo, que permaneceu pendurado por um pequeno fragmento de pele. Essa lesão resultou em uma enorme massa exuberante. Os exames laboratoriais revelaram anemia arregerenativa; as análises bacteriológicas produziram culturas de Pseudomonnas spp. E Arcanobacterium spp. A avaliação histopatológica revelou que a massa era formada predominantemente pelo carcinoma das células escamosas bem-diferenciado com áreas de neoplasia do epitélio glandular. A localização anatômica do tumor associado aos achados histopatológicos é consistente com o carcinoma da base do chifre.

    Dysembryoplastic neuroepithelial tumors (DNTs) are long-term epilepsy associated tumors subdivided into simple and complex variants. The purpose of this study was to relate different DNT components identified on magnetic resonance imaging (MRI) to histopathological features and to test the hypothesis that glial nodules as a histopathological feature of complex variants induce an occasional glioma misdiagnosis. Clinical, MRI, and histopathologic features of DNTs operated between 1988 and 2008 were reviewed. From a total of 61 DNTs, 48 simple and 13 complex variants were identified. Multiple or single pseudocysts in a cortical/subcortical location with small cysts sometimes separated from the tumor represented the glioneuronal element and were found in all DNTs. FLAIR hyperintense tissue was found between pseudocysts but - in neocortical DNTs - also circumscript in deeper tumor parts. Calcification and hemorrhages in this location occurred in four of 13 complex variants, and one of these patients was also the only one with tumor growth. Patients with complex variants had earlier seizure onset, and complex variants were more often located outside the temporal lobe. Although complex variants represented a higher diagnostic challenge, misdiagnoses also occurred in simple variants. One of five of DNTs showed contrast enhancement, which varied on follow-up studies with enhancing parts becoming nonenhancing and vice versa. The glioneuronal element is readily identifiable on MRI and should be considered to support the DNT diagnosis. Complex DNT variants have a different clinical profile and a more variable histopathological and MRI appearance; however, misdiagnoses occasionally also occur in simple variants. (orig.)

    The aim of the study is: 1) A sequential description of the clinical course of acute radiation proctitis during pelvic RT. 2) A sequential description of the rectal mucosal histopathology during pelvic RT as a possible substrate for clinical toxicity. 3) To assess the mucosal protease activity during RT as a possible explanation of the observed tissue changes. 4) To assess the efficacy of prophylactic sucralfate in acute radiation proctitis a randomised study was initiated and carried out together with a meta-analysis of previously available data. 5) Most studies on clinical acute toxicity in pelvic RT use either the RTOG/EORTC score system or focus on diarrhoea/stool frequency. A more differentiated and sensitive recording was developed and tested to pick up symptoms escaping the commonly used scores. 6) Study the relation between histopathological findings and the clinical picture. 4 papers presenting various studies are included. The titles are: 1) Acute radiation proctitis: a sequential clinicopathologic study during pelvic radiotherapy. 2) Clinical significance of increased gelatinolytic activity in the rectal mucosa during external beam radiation therapy of prostate cancer. 3) Profiles and time course of acute radiation toxicity symptoms during conformal radiotherapy for cancer of the prostate. 4) Sucralfate does not ameliorate acute radiation proctitis. Some future prospects are discussed.

    Full Text Available BACKGROUND: Lichen amyloidosus (LA is a primary localized cutaneous amyloidosis characterized clinically by discrete hyperkeratotic hyperpigmented papules and histologically by deposition of amyloid material in previously normal skin without any evidence of visceral involvement. AIMS AND OBJECTIVES: The aim of this work was to study the etiology, clinical features, histopathology and direct immunofluorescence findings in LA. METHODS: A prospective study of 30 patients with clinical, histological and immunofluorescence findings suggestive of LA was undertaken. After a detailed history and clinical examination, two punch biopsies for histopathology and immunofluorescence were taken. RESULTS: Of the 30 patients, 19 (63.3% were males and 11 (36.7% were females with duration of LA ranging from 6-20 months. Pruritus was the presenting symptom in 27 (90% patients. Shin was involved in 26 (86.7% followed by arms in three (10% and back in one (3.3%. Seventeen patients (56% had used scrubs for more than 2 years. Histopathology, direct immunofluorescence and Congo red staining detected amyloid in all cases. CONCLUSIONS: LA commonly presents over the shins as pruritic discrete hyperpigmented papules. Familial predisposition and friction may have a pathogenic role. Histopathological examination is very useful in the detection of amyloid which may be supplemented with direct immunofluorescence and Congo red staining.

    Full Text Available SUMMARY Objective: As a result of the use of neuroimaging techniques, silent pituitary lesions are diagnosed more and more frequently; however, there are few published post-mortem studies about this gland. Incidence data of pituitary lesions are rare and in Portugal they are outdated or even non-existent. The aim of this study is to determine the prevalence of normal patterns and incidental post-mortem pituitary pathology at Centro Hospitalar Lisboa Norte, analyzing the associations with clinical data and assessing the clinical relevance of the findings. Method: We reviewed retrospectively and histologically 167 pituitaries of a consecutive series of autopsies from the Department of Pathology of this centre. They were done between 2012 and 2014, and in all cases medical records were reviewed. The morphological patterns observed, were classified into three major groups: 1 Normal histological patterns and variants; 2 Infectious-inflammatory pathology, metabolic and vascular disorders; 3 Incidental primary proliferation and secondary to systemic diseases. Results: The subjects included in this study were of all age groups (from 1 day to 91 years old, 71 were female and 96 male. Fifty-seven of these glands didn’t show any alteration; 51 showed colloid cysts arising from Rathke cleft; 44 presented hyperplasia in adenohypophysis and we identified 20 adenomas in 19 glands (immunohistochemically, eight PRL-producing and five ACTH-producing tumors, ten of which associated with obesity, 11 to hypertension and six to diabetes mellitus. There were two cases with metastasis. Conclusion: Subclinical pathology in our country is similar to that seen in other parts of the world, but at older ages.

    Elastoma is a connective tissue nevus characterized by changes in elastic fibers. It can be congenital or acquired, and is usually diagnosed before puberty. Associated with osteopoikilosis, it is known as Buschke-Ollendorff syndrome. Histopathology with specific staining for elastic fibers is critical for a diagnostic conclusion. This report describes the case of a 7-year-old male patient with lesions diagnosed as elastoma, with absence of bone changes in the radiological imaging. This study aims to report the clinical presentation and histological examination of such unusual disease.

    Dermatopathology is considered the gold standard for melanoma diagnosis, but a subset of cases is difficult to diagnose by histopathology. The goals of this study were to measure the accuracy of histopathologic features in difficult-to-diagnose melanocytic tumors and the interobserver agreement of those features. This is a case-control study of histopathologic features of melanoma in 100 difficult-to-diagnose melanocytic neoplasms (40 melanomas and 60 nevi). Slides were blindly evaluated by 5 dermatopathologists. Frequencies, predictive values, and interobserver agreement were calculated. Univariate and multivariate logistic regression analyses were performed to identify the most influential features in arriving at a diagnosis of melanoma. Asymmetry, single-cell melanocytosis, solar elastosis, pagetoid melanocytosis, and broad surface diameter were most influential in arriving at a diagnosis of melanoma. Asymmetry and single-cell melanocytosis were most predictive of melanoma. Fleiss kappa was melanoma. This study is limited by the small sample size, selection bias, and binary classification of melanocytic lesions. Our results indicate histopathologic features of melanoma in difficult-to-diagnose lesions vary in accuracy and reproducibility. Copyright © 2017 American Academy of Dermatology, Inc.

    Multiparametric magnetic resonance (MR) imaging combines anatomic and functional imaging techniques for evaluating the prostate and is increasingly being used in diagnosis and management of prostate cancer. A wide spectrum of anatomic and pathologic processes in the prostate may masquerade as prostate cancer, complicating the imaging interpretation. The histopathologic and imaging findings of these potential mimics are reviewed. These entities include the anterior fibromuscular stroma, surgical capsule, central zone, periprostatic vein, periprostatic lymph nodes, benign prostatic hyperplasia (BPH), atrophy, necrosis, calcification, hemorrhage, and prostatitis. An understanding of the prostate zonal anatomy is helpful in distinguishing the anatomic entities from prostate cancer. The anterior fibromuscular stroma, surgical capsule, and central zone are characteristic anatomic features of the prostate with associated low T2 signal intensity due to dense fibromuscular tissue or complex crowded glandular tissue. BPH, atrophy, necrosis, calcification, and hemorrhage all have characteristic features with one or more individual multiparametric MR imaging modalities. Prostatitis constitutes a heterogeneous group of infective and inflammatory conditions including acute and chronic bacterial prostatitis, infective and noninfective granulomatous prostatitis, and malacoplakia. These entities are associated with variable clinical manifestations and are characterized by the histologic hallmark of marked inflammatory cellular infiltration. In some cases, these entities are indistinguishable from prostate cancer at multiparametric MR imaging and may even exhibit extraprostatic extension and lymphadenopathy, mimicking locally advanced prostate cancer. It is important for the radiologists interpreting prostate MR images to be aware of these pitfalls for accurate interpretation. PMID:26587887

    The objective of this study is to assess computed tomography (CT) changes, both volume estimates and subjective features, following preoperative chemotherapy for nephroblastoma (Wilms' tumour) in patients treated on the United Kingdom Children's Cancer Study Group Wilms' Tumour Study-3 (UKW-3) protocol and to compare CT changes and histopathological classification. Twenty-one nephroblastomas in 15 patients treated on UKW-3 were included. All patients were examined by CT before and after preoperative chemotherapy treatment. CT images were reviewed (estimated volume change and subjectively assessed features). CT changes were compared to histopathological classification. Of the 21 tumours, all five high-risk tumours decreased in volume following chemotherapy (median -79%; range -37 to -91%). The sole low-risk tumour decreased in volume by 98%. Ten intermediate-risk tumours decreased in volume (median -72%; range -6 to -98%) and five intermediate-risk tumours increased (median +110%; range +11 to +164%). None of the five high-risk tumours, compared to 15/16 intermediate or low-risk tumours, became less dense and/or more homogeneous, or virtually disappeared, following chemotherapy. Volume change following chemotherapy did not relate to histopathological risk group. Changes in subjectively assessed qualitative CT features were more strongly related to histopathological risk group. (orig.)

    Aim: To evaluate the ultrasound (US) features of the diffuse sclerosing variant of papillary carcinoma (DSVPC) of the thyroid, with histopathological correlations. Materials and methods: The US and histopathological findings of six patients with surgically proven DSVPC of the thyroid were retrospectively assessed. Results: Most of cases showed diffuse, scattered microcalcifications with or without associated masses and underlying heterogeneous hypoechogenicity at the site of the DSVPC in the thyroid. At ultrasound, scattered microcalcifications and heterogeneous hypoechogenicity seen in the DSVPC correlated to psammoma bodies and lymphocytic infiltration at histopathological review. Conclusion: DSVPC of the thyroid usually manifested as diffuse scattered microcalcifications and associated suspicious mass on ultrasound. These findings are not specific for the DSVPC of the thyroid. However, in relatively young patients with suspicious masses associated with underlying diffuse scattered microcalcifications on US, the possibility of DSVPC should be included in differential diagnosis.

    Full Text Available Female genital ulcer is a disease that affects a large number of women, and its etiologic diagnosis can be difficult. The disease may increase the risk of acquiring HIV. Genital ulcer may be present in sexually transmitted diseases (STD - syphilis, chancroid, genital herpes, donovanosis, lymphogranuloma venereum and other non-STD disorders (NSTD - Behçet's syndrome, pemphigus, Crohn's disease, erosive lichen planus and others. This study evaluated the clinical-histopathologic-microbiologic characteristics of female genital ulcers. A cross-sectional descriptive prospective study was conducted during a six-month period to investigate the first 53 women without a definitive diagnosis, seeking medical care for genital ulcers at a genital infections outpatient facility in a university hospital. A detailed and specific history was taken, followed by a dermatologic and gynecologic examination. In addition to collecting material from the lesions for microbiologic study, a biopsy of the ulcer was performed for histopathologic investigation. The average age of the patients was 32.7 years, 56.6% had junior high school education and higher education. The most frequent etiology was herpetic lesion, followed by auto-immune ulcers. At the time of their first consultation, around 60% of the women were using inadequate medication that was inconsistent with the final diagnosis. Histologic diagnosis was conclusive in only 26.4% of the patients (14/53. Cure was obtained in 99% of the cases after proper therapy. The female genital ulcers studied were equally distributed between sexually transmitted and non-sexually transmitted causes. Herpes was the most frequent type of genital ulcer, affecting women indiscriminately, mostly between the ages of 20 and 40 years.

    Condylar hyperplasia is a rare disorder characterized by an increased volume of the condyle, ramus, and mandibular body leading to facial asymmetry. We present three cases of condylar hyperplasia: two women and one man, age range 27 to 34. Clinically, all three patients showed a deviation of the mandible to the opposite side and a protruded position of the chin, hypertrophy of the lower border of the mandible, combined with an elongation of the mandibular ramus, open-bite on the deformed side, and cross-bite on the opposite side. In all three cases, scintigraphy showed an increased uptake. Radiography and CT scanning confirmed the clinical diagnosis and patients were subjected to surgery, comprising high condylectomy on the affected side with access in the pre-tragus area. The surgical piece sent to the Institute of Pathological Anatomy for histological examination revealed a nonuniform picture, in terms of both the depth of cartilage islands and the thickness of the fibrous layer covering the joint surface. Common to all three cases, however, was the apparent evolution of fibrous tissue to cartilage, and of this to compact bone tissue. At two-four years, all cases have maintained a good occlusal response. The asymmetric deformity of the mandible resulting from the rare condition of hemimandibular hyperplasia is presented and the clinical, histopathological and therapeutic aspects discussed.

    Full Text Available Background and Design: Lichen planopilaris (LPP is a type of cicatricial alopecia characterized by autoreactive lymphocytic destruction of the hair follicle. We aimed to evaluate the demographic, clinical and histopathological features, and treatment outcomes of patients with LPP. Materials and Methods: Medical reports of 25 patients, who have been diagnosed with LPP according to the clinical and histopathological findings between January 2006 and June 2012, were retrospectively reviewed. The transverse and vertical sections of scalp biopsy specimens were re-evaluated by a pathologist, and the findings were noted. Results: Of the 25 patients, 18 were female and 7 were male, the mean age was 49.8±12.4 years. Eighteen patients had been diagnosed with classic LPP and 7 patients with frontal fibrosing alopecia (FFA. The alopecia has begun in postmenopausal period in 5 patients with FFA. Alopecia was associated with pruritus, pain and/or burning in 19 patients. Extra-scalp involvement was observed in 11 patients. The most common clinical findings were follicular hyperkeratosis (92%, perifollicular erythema (48%, perifollicular lichenoid papules, and positive hair-pull test (44%. Dermatoscopic examination was performed in 14 patients, and most commonly, absence of follicular openings (100%, perifollicular scales (92.9% and perifollicular erythema (50% were noted. The most common diagnostic histopathological findingsmwere follicular vacuolar and lichenoid degeneration (88% and vacuolar and lichenoid interface changes (56%. Twenty-three patients who were started on treatment received topical, intramuscular and intralesional corticosteroids, topical minoxidil, oral tetracycline, cyclosporine A, and hydroxychloroquine either alone or in combination. Progression of alopecia was prevented and the symptoms and/or signs were reduced in 12 (75% of 16 patients whose follow-up data were available.

    Benign lichenoid keratosis is a cutaneous entity that consists of a nonpruritic papule or slightly indurated plaque that is histologically characterized by a band-like inflammatory infiltrate with interface involvement. The purpose of this study was to investigate the clinical and histopathologic features of benign lichenoid keratosis localized on the face. Fourteen benign lichenoid keratosis patients diagnosed clinically and histopathologically in our clinic during the 10-year period from 2002 to 2012 were studied. Thirteen female and 1 male patients were included. The mean age at diagnosis was 46.5 years. The color of most of the lesions was brown (10 cases, 71%). The cheek was the most commonly involved area (10 cases, 71%). All of the lesions were single. There were 9 (64%) flat lesion cases and 5 (36%) raised lesion cases. Most patients denied having any symptoms; 3 had mild pruritus. The histopathological findings indicated that all the cases exhibited lichenoid inflammatory infiltrate obscuring the dermal-epidermal junction and vacuolar alteration of basal cell layer. The lesions showed focal parakeratosis (79%), melanophages (79%), hyperkeratosis (71%), and necrotic keratinocytes (71%). Solar elastosis (50%) and acanthosis (43%) were also seen frequently. Diagnosis of benign lichenoid keratosis should be made by a combination of clinical manifestations and histopathological findings. In particular, benign lichenoid keratosis should be considered if a middle-aged patient presents a solitary asymptomatic brown lesion on the face. We think benign lichenoid keratosis may be a specific disorder rather than the inflammatory stage of regressing solar lentigines, large cell acanthoma or reticulated seborrheic keratosis.

    In this work, cellular mitosis detection in histopathological images has been investigated. Mitosis detection is very expensive and time consuming process. Development of digital imaging in pathology has enabled reasonable and effective solution to this problem. Segmentation of digital images provides easier analysis of cell structures in histopathological data. To differentiate normal and mitotic cells in histopathological images, feature extraction step is very crucial step for the system accuracy. A mitotic cell has more distinctive textural dissimilarities than the other normal cells. Hence, it is important to incorporate spatial information in feature extraction or in post-processing steps. As a main part of this study, Haralick texture descriptor has been proposed with different spatial window sizes in RGB and La*b* color spaces. So, spatial dependencies of normal and mitotic cellular pixels can be evaluated within different pixel neighborhoods. Extracted features are compared with various sample sizes by Support Vector Machines using k-fold cross validation method. According to the represented results, it has been shown that separation accuracy on mitotic and non-mitotic cellular pixels gets better with the increasing size of spatial window.

    BACKGROUND American tegumentary leishmaniasis has an annual incidence of 1 to 1.5 million cases. In some cases, the patient's immune response can eliminate the parasite, and the lesion spontaneously resolves. However, when this does not occur, patients develop the disseminated form of the disease. OBJECTIVE To investigate the association between clinical, laboratory and pathological findings in cases of American tegumentary leishmaniasis. METHODS A retrospective study of the medical records of 47 patients with American cutaneous leishmaniasis. Clinical, laboratory and epidemiological data were collected, and semi-quantitative histopathological analyses were performed using the Spearman correlation coefficient (p Montenegro reaction, degree of granulomatous transformation and epithelioid cell count; duration of disease, Montenegro reaction and number of lymphocytes; epithelial hyperplasia and edema, hemorrhaging, and epithelial aggression; number of plasmocytes and number of parasites. The main negative correlations found were as follows: age and serology; time and parasite load; epithelial hyperplasia and degree of granulomatous transformation. CONCLUSION The long duration of the disease could be explained by the fact that lesions were relatively asymptomatic, and therefore ignored by patients with low literacy levels. Individuals may have simply waited for spontaneous healing, which proved to be dependent on the activation of hypersensitivity mechanisms. PMID:24626648

    Lichen sclerosus et atrophicus and limited systemic scleroderma (acrosclerosis) are inflammatory skin diseases that ultimately evolve into two distinct modes of atrophic scar formation, but which can easily be confused clinically. They are very rarely associated. The literature has reported cases in which lichen sclerosus was associated with various forms of scleroderma, but often with localized morphea. The characteristic histopathological picture of lichen sclerosus includes a thin epidermis, with orthohyperkeratosis and vascular degeneration in the basal layer, loss of elastic fibers, and band-like inflammatory infiltrate in the papillary dermis, while systemic sclerosis is characterized by excessive deposition of collagen in the dermis, accompanied by reduction in adnexal structures and their entrapment in collagen, and the presence of perivascular lymphocytic inflammatory infiltrate. We present the case of a 40-year-old female patient clinically diagnosed with systemic scleroderma and lichen sclerosus involving the genital mucosa. Physical examination in conjunction with laboratory findings (elevated antinuclear, anti-Scl-70, anti-SSA antibodies and immunogram) induced the supposition of the coexistence of lichen sclerosus and systemic scleroderma, fact confirmed by pathological examination. Systemic therapy with corticosteroids, immunosuppressive and phlebotropic drugs, peripheral vasodilators and other tropic adjuvants and topically potent topical corticosteroids was initiated. The course was favorable under therapy, the hardened skin slightly regaining elasticity, relief of itching and disappearance of lichen sclerosus lesions. Our case reaffirms the uncommon association of these two disorders. The importance of history, physical and laboratory examinations in making a diagnosis of certainty in emphasized.

    Periodontal disease is one of the most frequent diseases affecting people all over the world. The relation between periodontal disease and diabetes mellitus raised the interest both of dentists and doctors treating metabolic diseases, as the two conditions influence one another. In our study, we analyzed a number of 75 patients with diabetes mellitus and periodontal disease that presented to the medical consultory for conditions of the dental maxillary system. The clinical study showed that periodontal disease and diabetes may affect young adults as well, still this pathological association more frequently appears after the age of 50. The disease was identified especially in the women living in urban area. The clinical examination of the dental maxillary system identified the presence of gingival ulcerations, dental calculus, gingival bleeding, radicular leftovers with anfractuous margins, fixed prostheses with an inappropriate cervical adjustment. Of the systemic diseases associated to periodontal disease and diabetes mellitus, there was observed that 66.66% of the patients also suffered from cardiovascular diseases (high blood pressure, ischemic cardiopathy, heart failure), and 37.33% suffered from obesity. The histopathological and immunohistochemical tests highlighted the presence of an inflammatory chronic, intense reaction, mainly formed of lymphocytes, plasmocytes, macrophages and granulocytes, heterogeneously disseminated and alteration of the structure of marginal and superficial periodontium. The inflammatory reaction in the patients with periodontal disease and diabetes was more intense than in the patients with periodontal disease without diabetes.

    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.

    Full Text Available We report a case of cutaneous Stenotrophomonas maltophilia infection which presented with clinical and histopathological findings that mimicked a gamma/delta (γδ T-cell lymphoma. In this case, tissue culture of the biopsy specimen was key to determining the diagnosis and allowing appropriate treatment with oral trimethoprim–sulfamethoxazole and topical silvadene. A prompt complete resolution of lesions was observed following antibiotic treatment, with no recurrence of disease over the last 5 years, supporting an infectious rather than malignant etiology. In our patient, radiation therapy was indicated based on the misdiagnosis of γδ T-cell lymphoma, which was supported both clinically and histopathologically. However, tissue culture in this case avoided unnecessary radiation exposure and highlights the role of tissue culture in the evaluation of the biopsy of an undiagnosed cutaneous lesion.

    The purpose of this paper was to evaluate the relationship between the thrombosis and secretory duct dilation, lesion size, clinical types, nature (primary or recurrent) and duration of illness in the development of ranula. A total of 229 cases of sublingual gland cysts were treated with surgical resection from Jan. 1990 to Feb. 2010. The patients' data were investigated on histopathological findings, size of ranula, the clinical types, nature of ranula (primary or recurrent) and duration of illness. Sections from the paraffin-embedded blocks were HE-stained. CK expression was immunohistochemically detected. Among 229 cases the incidence of venous thrombosis was 58.52%. The incidence of venous thrombosis with or without duct dilation was 73.25% and 26.39% respectively, with a significant difference between the two groups (Pranulas with diameter larger or less than 3 cm was 72.22% and 46.28% (Pranula, plunging ranula and mixed ranula was 49.37%, 77.19% and 85.71% respectively, with a significant difference found between oral and plunging or mixed ranula (Pranula patients with duration of illness longer or less than 3 months was 69.77% and 51.75% (Pranulas was 51.85% and 64.85%, without a significant difference noted between them (P>0.05). It is concluded that the formation of venous thrombosis was related to the dilation of secretory duct, lesion size, clinical types, duration of lesion but formation of venous thrombosis was not related to the nature (primary or recurrent) of ranulas.

    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

    Objective: To study the relationship between histopathology and clinical prognosis of invasive pituitary adenoma subjected to transsphenoidal surgery. Methods: The enrolled were 82 patients with invasive pituitary adenomas undergoing transsphenoidal surgery during Jan. 2000 May 2003 in our department with full MR imaging findings, pathology data and follow-up information. The follow-up duration was 5-30 months. Results: MR imaging findings of invasive pituitary adenoma included: depression of the sellar floor, involvement of sphenoid sinus and cavernous sinus, breakthrough of diaphragma sellae,encasement of internal carotid artery, etc. Pathological examination revealed that the invasion rate of dura in sella turcica was the highest among the structures around tumor. Pituitary adenoma apoplexy was found in 20 cases (24.4%). The total removal rate for PRL-secreting adenomas was significantly lower than that for non-secreting adenomas (P<0.01), but non-, GH-, ACTH-secreting adenomas had no significant differences. The recurrence rate of PRL-secreting adenornas was higher than that of non- and GH-secreting adenomas (P<0.05). Conclusion: Among invasive pituitary adenomas, the therapeutic effects of nonand GH-secreting pituitary adenomas are better than that of PRL-secreting adenomas. Invasive biological behaviors of invasive pituitary adenomas result in radical operation failure and postoperative recurrence.

    Compared with the proven utility of flow cytometry immunophenotyping (FCI) analysis in the workup of myelodysplastic syndromes (MDS), immunophenotypic alterations in myeloproliferative neoplasms (MPN) have been less studied and the potential utility of FCI is not defined. Bone marrow (BM) samples of 83 Philadelphia-negative MPN patients were assessed by multicolor FCI including 27 with essential thrombocythemia (ET); 17 polycythemia vera (PV); 33 primary myelofibrosis (PMF) and 6 MPN-unclassifiable (MPN-U). The time interval from initial diagnosis of MPN to FCI analysis was 18 months (0-370). Ninety-five age-matched MDS patients with a similar BM blast count were included for comparison. Immunophenotypic alterations, either in CD34(+) cells or myelomonocytic cells, were detected in 82 of 83 (99%) MPN cases. FCI abnormalities were more frequently observed in cases with substantial myelofibrosis but not different between PMF and fibrotic stage of ET/PV. Furthermore, FCI abnormalities were more frequent in cases with ≥5% BM blasts and/or circulating blasts (P = 0.006); as well as cases with an abnormal karyotype (P = 0.036); but not associated with morphologic dysplasia or JAK2 mutation status. Comparing with MDS, FCI abnormalities were overall less pronounced in MPN cases (P = 0.001). MPNs exhibit frequent immunophenotypic alterations, more pronounced in cases with adverse histopathologic features. These findings illustrate that immunophenotypic alterations are a part of constellational findings in MPN, and correlate progressively with disease stage. The study results also suggest a role of FCI in diagnosis of MPN and monitoring disease over time and after therapy. © 2014 International Clinical Cytometry Society.

    Full Text Available Acute appendicitis is one of the most common surgical conditions that affect about seven percent of the population. The histopathologic stages of appendicitis are important to regarding prognosis. To evaluate pathologic features of appendix after operation, this study was designed. 2753 appendices specimen that had been received to department of pathology of two major hospitals in Kerman-Iran during five years periods were reviewed by two pathologist and classification was performed by followed: Normal, early acute, acute, suppurative or purulent, gangrenous and perforated appendicitis. There were 54.6% males, the average age of patients was 24.9+/-13.3 (mean+/-SD, that 76.6% was under 30 years old. 34.2% of reports were normal histopathologically. The accuracy rate of acute appendicitis was 65.8%. Perforation observed to 0.8%. There was significant difference between sex and stage of development of appendicitis. Seasonal incidence was difference in various histopathology views, significantly. Finally, acute appendicitis was more frequent in men than women and was increase by age specially 19-30 years. Our results showed appendicitis was more frequent and higher in stage at winter.

    To evaluate MRI features of response of primary extremity liposarcoma (LPS) to neoadjuvant radiation therapy (RT) with histopathologic correlation. In this IRB-approved study including 125 patients with extremity LPS treated with neoadjuvant RT from 2000 to 2013, MRI of the primary tumour in 18 patients (5 pleomorphic LPS, 13 myxoid LPS) before and after RT were reviewed by two radiologists by consensus. Histopathology of the surgical specimens was reviewed by a pathologist with expertise in sarcomas. In the pleomorphic LPS cohort, 3/5 tumours increased in size; 3/5 decreased in enhancing component; and 3/5 increased in peritumoral oedema, intratumoral haemorrhage, and necrosis. In the myxoid LPS cohort, 12/13 tumours decreased in size, 8/13 decreased in enhancing component, and 5/13 increased in internal fat following RT. Histopathology showed ≥50 % residual tumour in 1/5 pleomorphic LPS and 2/13 myxoid LPS. Hyalinization/necrosis of ≥75 % was noted in 4/5 pleomorphic LPS and 11/13 myxoid LPS. Cytodifferentiation was noted in 1/5 pleomorphic and 9/13 myxoid LPS. While pleomorphic LPS showed an increase in size, peritumoral oedema, intratumoral haemorrhage, and necrosis on MRI following neoadjuvant RT, myxoid LPS showed a decrease in size and enhancement with an increase in internal fat.

    Histopathologic features could affect the FDG uptake of primary gastric cancer and detection rate on FDG PET/CT. The aim of this study was to evaluate the FDG uptake of primary gastric cancer by correlating it with the histopathologic features of the tumors. Fifty patients with locally advanced gastric adenocarcinoma who were referred for preoperative FDG-PET/CT scans were enrolled in this study. The detection rate of PET/CT and maximum standardized uptake values (SUV{sub max}) of the primary tumor were compared using the WHO, Lauren, Ming and Borrmann classifications and tumor size and location. In 45 of the 50 patients (90 %), the primary gastric tumors were detected by FDG PET/CT. On comparison using the WHO classification, the detection rate and SUV{sub max} of the tubular type were significantly higher than those of the poorly cohesive type. On comparison using the Lauren and Ming classifications, the SUV{sub maxs} of the intestinal type and expanding type were significantly higher than those of the diffuse and infiltrative type, respectively. On comparison using the Borrmann classification and tumor size and location, there was no significant difference in the detection rate and SUV{sub max} of primary gastric tumors. This study demonstrates that the poorly cohesive type according to the WHO classification, diffuse type according to the Lauren classification and infiltrative type according to the Ming classification have low FDG uptake in patients with locally advanced gastric carcinoma. Understanding the relationship between primary tumor FDG uptake and histopathologic features would be helpful in detecting the primary tumor by FDG PET/CT in patients with gastric cancer.

    The purpose of this study was to analyze the computed tomography (CT) features of fungal sinusitis and to correlate them with nasal endoscopy and histopathological findings. Our study included 16 patients of either sex and any age group who presented in the otorhinolaryngology clinic at our hospital and had evidence of definite sinonasal disease on clinical evaluation. Multidetector CT was carried out on Somatom definition AS + 128 slice CT Machine by Siemens Germany Ltd. Axial sections were performed with the plane of data acquisition parallel to the hard palate and slice thickness of 3 mm, reconstructions at 0.75 mm in coronal and sagittal planes. Scanning parameters included 190 mA S, 120 KV and tube rotation time of 0.5 s. Provisional CT diagnosis was made in all cases and correlated with nasal endoscopy and histopathological findings. Out of total 16 patients, 12 showed immunocompromised status and had infection with mucormycosis. Out of 12, 9 patients (75%) showed extension of disease beyond the sinonasal cavities and 4 (33.3%) showed evidence of bone destruction. All patients with candidiasis showed soft-tissue attenuation with hyperdense areas on CT scan. Nearly, 66.6% patients with aspergillosis showed soft-tissue attenuation with hyperdense areas and expansion of sinonasal cavities. Fifteen patients (93%) were proved to be of fungal sinusitis on histopathology. One patient of non-specific granulomatous infection showed bone destruction and mimicked fungal sinusitis on CT. In the present study, fungal sinusitis could be correctly diagnosed on CT with high accuracy. Thus, understanding the different CT findings of fungal sinusitis allows the radiologist to play a crucial role in the diagnosis and prompt treatment.

    Oral cancer (OC) is the sixth most common cancer in the world. In India it is the most common malignant neoplasm. Histopathological images have widely been used in the differential diagnosis of normal, oral precancerous (oral sub-mucous fibrosis (OSF)) and cancer lesions. However, this technique is limited by subjective interpretations and less accurate diagnosis. The objective of this work is to improve the classification accuracy based on textural features in the development of a computer assisted screening of OSF. The approach introduced here is to grade the histopathological tissue sections into normal, OSF without Dysplasia (OSFWD) and OSF with Dysplasia (OSFD), which would help the oral onco-pathologists to screen the subjects rapidly. The biopsy sections are stained with H&E. The optical density of the pixels in the light microscopic images is recorded and represented as matrix quantized as integers from 0 to 255 for each fundamental color (Red, Green, Blue), resulting in a M×N×3 matrix of integers. Depending on either normal or OSF condition, the image has various granular structures which are self similar patterns at different scales termed "texture". We have extracted these textural changes using Higher Order Spectra (HOS), Local Binary Pattern (LBP), and Laws Texture Energy (LTE) from the histopathological images (normal, OSFWD and OSFD). These feature vectors were fed to five different classifiers: Decision Tree (DT), Sugeno Fuzzy, Gaussian Mixture Model (GMM), K-Nearest Neighbor (K-NN), Radial Basis Probabilistic Neural Network (RBPNN) to select the best classifier. Our results show that combination of texture and HOS features coupled with Fuzzy classifier resulted in 95.7% accuracy, sensitivity and specificity of 94.5% and 98.8% respectively. Finally, we have proposed a novel integrated index called Oral Malignancy Index (OMI) using the HOS, LBP, LTE features, to diagnose benign or malignant tissues using just one number. We hope that this OMI can

    Full Text Available Objective:This research aims to establish the prevalence, factors associated with the onset, and clinical and histopathological features of oral leukoplakia and erythroplakia, so that these data can contribute to the prevention of these lesions and, consequently, of oral cancer.Material and method:A retrospective study was conducted at a reference service of Universidade Federal do Rio Grande do Norte (UFRN from 2000 to 2012. To verify the association of variables, Pearson's chi-squared test and Fisher's exact test (p ≤ 0.05 were used.Results:Among 6,560 investigated records, 54 cases were selected, of which 44.4% were male and 55.6% female, with mean age of 56.93 years. Regarding habits, 72.2% were smokers and 25% were alcohol users; 17.9% showed association of both habits. Oral leukoplakia lesions were the most prevalent (0.65% and oral erythroplakia showed greater association with malignancy in the histopathological presentation (p = 0.001. Most lesions showed no symptoms (p = 0.004. The most frequent was oral leukoplakia in smoking women, with mean age of 57 years.Conclusion:Knowledge of associated factors and clinical characteristics of oral leukoplakia and erythroplakia is essential for establishing the correct diagnosis and treatment.

    A retrospective study over 26 female patients with chronic active hepatitis was made. The mean age was 39 years old, the mean length of illness of 8 months; 5 patients had positive markers for hepatitis B. Patients were selected with the grade of histological activity: 8 patients had a mild form from disease (2A) and 16 with a severe one (2B). The predominant group was 2B. Severe inflammatory infiltration was the hallmark and multiobulillar necrosis, bridging, eosinophils and hiperplasia of kuppfer cells were found only in this group. Clinical features range from hepatic manifestations to systemic ones. Chronic active hepatitis may present with cholestasis, but the latter is not always related with the grade of activity. Group 2B had elevated aminotransferases and a low concentration for protrobine.

    Full Text Available ABSTRACTINTRODUCTION:The aim of this study was quantify annexin A1 expression in macrophages and cluster of differentiation 4 (CD4 + and cluster of differentiation 8 (CD8+ T cells from the skin of patients with cutaneous leishmaniasis (n=55 and correlate with histopathological aspects.METHODS:Infecting species were identified by polymerase chain reaction-restriction fragment length polymorphism, and expression of annexin A1 was analyzed by immunofluorescence.RESULTS:All patients (n = 55 were infected with Leishmania braziliensis . Annexin A1 was expressed more abundantly in CD163 + macrophages in infected skin (p < 0.0001 than in uninfected skin. In addition, macrophages in necrotic exudative reaction lesions expressed annexin A1 at higher levels than those observed in granulomatous (p < 0.01 and cellular lesions p < 0.05. This difference might be due to the need to clear both parasites and necrotic tissue from necrotic lesions. CD4 + cells in cellular lesions expressed annexin A1 more abundantly than did those in necrotic (p < 0.05 and granulomatous lesions (p < 0.01. Expression in CD8 + T cells followed the same trend. These differences might be due to the pervasiveness of lymphohistiocytic and plasmacytic infiltrate in cellular lesions.CONCLUSIONS:Annexin A1 is differentially expressed in CD163 + macrophages and T cells depending on the histopathological features of Leishmania -infected skin, which might affect cell activation.

    Full Text Available Purpose: To report micro- and ultrastructural features of internal limiting membranes (ILMs in various maculopathies and to evaluate the effects of indocyanine green (ICG and triamcinolone acetonide (TA on epiretinal proliferations associated with ILM and on retinal cleavage plane. Methods: ILMs from various maculopathies were evaluated regarding presence or absence of membrane-associated cells, type of cells and ILM thickness based on routine histopathology, immunohistochemistry and transmission electron microscopy (TEM. Results: Thirty ILM specimens were enrolled; 25 of which were evaluated by histopathology and immunohistochemistry and 5 by TEM. ICG only had been used in 17 specimens, TA in 4, and both agents in one specimen. The majority of specimens were immunoreactive for glial fibrillary acidic protein and neuron specific enolase. No significant difference in specimen cellularity and alteration of cleavage plane was noted between ICG-stained and non-ICG-stained ILMs or between TA-assisted and non-TAassisted ones. Excluding central retinal vein occlusion (CRVO cases, acellularity was not observed in any of ILMs from diabetic macular edema (DME, cystoid macular edema (CME, and traumatic macular hole (TMH eyes. TEM disclosed ILM thickening and cellularity in DME as compared to CRVO. Conclusion: Acellular membranes from CRVO maculopathy may be a sequel of acute retinal ischemia. Thickened diabetic ILMs with high cellularity may be related to chronic activation of Muller cells. No obvious influence of ICG or TA on epiretinal cellularity was detected and the dyes seem to have no significant effect on cleavage plane.

    Background We tested the relevance of clinical information in the histopathologic evaluation of melanocytic skin neoplasm (MSN). Methods Histopathologic specimens from 99 clinically atypical MSN were circulated among ten histopathologists; each case had clinical information available in a database with a five-step procedure (no information; age/sex/location; clinical diagnosis; clinical image; dermoscopic image); each step had a histopathologic diagnosis (D1 through D5); each diagnostic step had a level of diagnostic confidence (LDC) ranging from 1 (no diagnostic certainty) to 5 (absolute diagnostic certainty). The comparison of the LDC was employed with an analysis of variance (ANOVA) for repeated measures. Findings In D1 (no information), 36/99 cases (36.3%) had unanimous diagnosis; in D5 (full information available), 51/99 cases (51.5%) had unanimous diagnosis (p for difference between proportions <0.001). The observer agreement expressed as kappa increased significantly from D1 to D5. The mean LDC linearly increased for each observer from D1 through D5 (p for linear trend <0.001). On average, each histopathologist changed his initial diagnosis in 7 cases (range: 2–23). Most diagnostic changes were in D2 (age/sex/location). Interpretation The histopathologic criteria for the diagnosis of MSN can work as such, but the final histopathologic diagnosis is a clinically-aided interpretation. Clinical data sometimes reverse the initial histopathologic evaluation. PMID:19404399

    We aimed to assess the validity of the American Joint Committee on Cancer (AJCC) tumor-node-metastasis (TNM) staging system in patients with papillary thyroid carcinoma (PTC) by evaluating the relationships between clinicopathologic factors and TNM stage using histopathological specimens and electronic medical records. We enrolled 733 consecutive patients who had undergone thyroid surgery for PTC between 2010 and 2013. Clinical data were obtained from electronic medical records. TNM stages, multifocality, and bilaterality were analyzed after review of histopathological specimens by applying the AJCC TNM staging system. Multiple statistical analyses were performed to evaluate the correlation between the AJCC TNM staging system and the clinicopathologic factors. Of the 733 patients, there were T stage including T1a (46.9 %, 344/733), T1b (12.6 %, 92/733), T2 (2.0 %, 15/733), T3 (38.1 %, 279/733), T4a (0.4 %, 3/733), and T4b (0 %, 0/733), N stage including N0 (58.9 %, 432/733), N1a (24.3 %, 178/733), and N1b (16.8 %, 123/733), and multiplicity including multifocality (31.1 %, 228/733) and bilaterality (23.7 %, 174/733). There was a significant association between the PTC primary tumor size and T stage, N stage, multifocality, and bilaterality (p TNM staging system, and these factors were independent predictors of multifocality and bilaterality.

    Accurate counting of mitosis in breast cancer histopathology plays a critical role in the grading process. Manual counting of mitosis is tedious and subject to considerable inter- and intra-reader variations. This work aims at improving the accuracy of mitosis detection by selecting the color channels that better capture the statistical and morphological features having mitosis discrimination from other objects. The proposed framework includes comprehensive analysis of first and second order statistical features together with morphological features in selected color channels and a study on balancing the skewed dataset using SMOTE method for increasing the predictive accuracy of mitosis classification. The proposed framework has been evaluated on MITOS data set during an ICPR 2012 contest and ranked second from 17 finalists. The proposed framework achieved 74% detection rate, 70% precision and 72% F-Measure. In future work, we plan to apply our mitosis detection tool to images produced by different types of slide scanners, including multi-spectral and multi-focal microscopy.

    Full Text Available Differentiating hereditary motor sensory neuropathy (HMSN from chronic inflammatory demyelinating polyneuropathy (CIDP is often difficult especially when the disease starts at an early age and has protracted course. This study compares the clinical, electro, physiological and histopathological features of hereditary and acquired chronic demyelinating neuropathies. Records of 26 patients of chronic demyelinating neuropathy who underwent sural nerve biopsy were reviewed; HMSN 9, CIDP 13, chronic relapsing demyelinating polyneuropathy (CRDP-4, Salient features of the HMSN group were: Consanguineous parentage-4, onset in first decade-9, skeletal markers-7, absence of positive sensory symptoms- 7 and clinically thickened nerves-6. None of the patients with acquired neuropathy had skeletal markers, 11 had positive sensory symptoms and only 4 had nerve thickening. Electrophysiological evaluation in 22 motor nerves in the HMSN group revealed: inexcitable nerves -13, prolonged distal latency - 6, slow conduction velocity-8 and prolonged f wave latency-3. The 44 motor nerves in patients with acquired neuropathy showed: inexcitable nerves- 7, prolonged distal latency-35, slow conduction velocity-34, f wave prolongation-30 and conduction block 9. Elevated CSF protein was noticed only in acquired group (77%. Pathologically in HMSN the fibre loss was always diffuse and onion bulb formation was frequent while endoneural edema and inflammatory infiltration were absent in this group. Selection of patients with chronic demyelinating neuropathies for therapeutic modulation needs comprehensive clinical and laboratory evaluation.

    Extrapleural solitary fibrous tumors are uncommon mesenchymal neoplasms frequently observed in middle-aged adults and are classified, according to the WHO classification of soft tissue tumors, as part of the hemangiopericytoma tumor group. However, these two entities remain separated in the WHO classification of tumors of the central nervous system. In fact, meningeal solitary fibrous tumors are believed to be benign lesion and only in a minority of cases local relapses have been described, although detailed survival clinical studies on solitary fibrous tumors of meninges are rare. In contrast to hemangiopericytoma, which frequently shows distant extracranial metastases, such an event is exceptional in patients with meningeal solitary fibrous tumors and has been clinically reported in a handful of cases only and their histopathological features have not been investigated in detail. In this report, we describe the detailed clinico-pathological features of a meningeal solitary fibrous tumor presenting during a 17-year follow-up period, multiple intra-, extracranial relapses and lung metastases.

    Full Text Available Statement of Problems: Sufficient knowledge, experience and careful examination usually lead to appropriate clinical diagnosis. However, lesions with similar clinical features present a diagnostic challenge. Therefore, a confirmatory histopathological examination can be helpful to reach the final diagnosis. Purpose: The present study was conducted to evaluate the agreement between clinical and histopathological diagnoses of oral epithelial and mesenchymal lesions in a period of 30-years (1976-2006 at Mashhad Dental School.Materials and Methods: The percentage of concurrence and discrepancy between clinical and histopathological diagnoses of 625 epithelial and 2480 mesenchymal lesions was compared. Clinical data including the patient’s gender and age and the lesion’s location were also evaluated in cases with discrepancy. Data were analyzed using Mann-Whitney, T-Test, Chi-Square, Likehood Ratio, Fisher’s Exact and Kappa tests.Results: An overall agreement between clinical and histopathological diagnoses was seen in 71/4% of epithelial lesion cases, with maximum parity in squamous cell carcinoma and papilloma. In 57/1% of the mesenchymal cases, the diagnosis was in total agreement. Denture hyperplasia, epulis fissuratum, and pregnancy tumor showed the highest concurrence, respectively.Conclusion: Although histopathological examination leads to final diagnosis, in some cases proper strategies and more attention to clinical features of the lesion are necessary to minimize the discrepancy, especially for those with non-specific clinical presentation.

    Full Text Available Background: tumors of the ocular adnexa are a common cause of patient visits to the Ophthalmology consultation. An adequate clinical-pathological relationship is important for prognosis. Objective: to describe the correspondence between clinical and histopathological diagnosis of tumors of the ocular adnexa. Methods: a case series study was conducted in patients who underwent a histopathological study due to suspicion of malignancy treated at the Oculoplastic Service of the Ophthalmology Center of the Dr. Gustavo Aldereguía University General Hospital, from January 2014 to the same month of 2015. The variables analyzed were: age, skin color, type of tumor, correspondence between clinical and histopathological diagnosis and safety margin. Results: correspondence between clinical and histopathological diagnosis was 79.1 %. The 40-59 age group was the most affected, with a higher incidence in females. The most common location was the eyelid region in white patients. Benign lesions of the eyelid and conjunctiva predominated. Conjunctival carcinoma and basal cell carcinoma were the most common malignancies; the safety margin was 2.19 %. Conclusions: an adequate correspondence between presumptive and histopathological diagnosis was observed. The safety margin achieved was satisfactory.

    The aim of the study was to analyze the histopathological characteristics of samples with a diagnosis of oral lichenoid disease (OLD) and their link with the location and the type of clinical lesion, and the clinicopathological subtypes. Retrospective study on 85 consecutive patients diagnosed with OLD (58 women and 27 men, mean age of 57.7 years). Clinical and histopathological characterization of each case (modified WHO criteria). Collection of the clinical and histopathological data of the lesions. Descriptive and comparative statistical analysis of the results. The 78.8% of the cases were considered clinically typical while the 21.2% were considered compatible. Histologically, 52.9% were classified as typical and 47.1% as compatible. Biopsies from "plaque-like" lesions presented hyperkeratosis (p>0.001) and epithelial dysplasia (p=0.06) more frequently. Furthermore, acute inflammation was more evident in erosive-ulcerative lesions (p=0.001). Differences regarding the location of the biopsy were statistically non-significant. However, 42.9% of the tongue biopsies showed epithelial dysplasia. The histopathological aspect of this disorder is not specific and does not allow us to differentiate between the main subtypes. Therefore, the main reasons to perform a biopsy in this disorder are to define the differential diagnosis and to rule out epithelial dysplasia or a carcinoma. The final histopathological result may be subject to the type of lesion that is biopsied.

    Acromegaly is a rare and underdiagnosed disorder caused, in more than 95% of cases, by a growth hormone (GH)-secreting pituitary adenoma. The GH hypersecretion leads to overproduction of insulin-like growth factor 1 (IGF-1) which results in a multisystem disease characterized by somatic overgrowth, multiple comorbidities, physical disfigurement, and increased mortality. This article aims to review the clinical features of acromegaly at diagnosis. Acromegaly affects both males and females equally and the average age at diagnosis ranges from 40 to 50 years (up to 5% of cases acromegaly is often diagnosed five to more than ten years after its onset. The typical coarsening of facial features include furrowing of fronthead, pronounced brow protrusion, enlargement of the nose and the ears, thickening of the lips, skin wrinkles and nasolabial folds, as well as mandibular prognathism that leads to dental malocclusion and increased interdental spacing. Excessive growth of hands and feet (predominantly due to soft tissue swelling) is present in the vast majority of acromegalic patients. Gigantism accounts for up to 5% of cases and occurs when the excess of GH becomes manifest in the young, before the epiphyseal fusion. The disease also has rheumatologic, cardiovascular, respiratory, neoplastic, neurological, and metabolic manifestations which negatively impact its prognosis and patients quality of life. Less than 15% of acromegalic patients actively seek medical attention for change in appearance or enlargement of the extremities. The presentation of acromegaly is more often related to its systemic comorbidities or to local tumor effects.

    Full Text Available Background: Immunobullous diseases are morphologically heterogeneous and the differentiation between various subtypes is essential for proper treatment and prognosis. Aim of our study was to analyze and correlate clinical, histopathological and immunofluorescence findings in autoimmune bullous diseases. Materials and Methods: A cross-sectional study was done over a period of two years (2010-2012 after approval of the ethics committee. Sixty patients, who met the inclusion criteria of immunobullous disease, were included in the study. Skin biopsy for histopathology and direct immunofluorescence (DIF examination was taken. DIF using salt-split technique was done in few of the cases. The final diagnosis was based on clinical, histopathology and DIF findings. Pearson′s coefficient of correlation (r was calculated. Statistical Analysis was done using Epi info version. 7.0. Results: Fifty-three cases with clinical diagnosis of autoimmune bullous diseases were evaluated. In 88.6% of cases, histopathology diagnosis was consistent with clinical diagnosis and in 75.5% of cases, DIF findings were consistent with clinical diagnosis. A positive relation was seen between clinical and DIF findings with r = 0.65 and between histopathology and DIF findings with r = 0.75. DIF positivity was seen in 100% cases of bullous pemphigoid (BP and pemphigus foliaceous and 94.7% cases of pemphigus vulgaris, which was statistically significant with p < 0.05. In DIF salt-split test, deposition was seen on roof of blister in BP whereas on floor in epidermolysis bullosa acquisita. Conclusion: Our study provides evidence-based guidance for the diagnosis and classification of various immunobullous disorders. DIF test should be done in conjunction with histopathology for definitive diagnosis and to minimize both: False-positive and false-negative results.

    Full Text Available In the present study, we describe a subcutaneous mass between the left flank and hip in a 2-year-old male Great Dane dog. Histopathologically, cells appeared to be spindle shaped around a central capillary together with a fingerprint pattern. Immunohistochemical analysis presented that the neoplastic cells expressed vimentin, but did not stain for S-100 protein. On the basis of histopathology and immunohistochemical findings, the present tumor was diagnosed as canine hemangiopericytoma. Hemangiopericytoma could be considered in differential diagnosis list of any mass in the skin (even in young dogs and must be identified histopathologically.

    To evaluate a possible association of shoulder pain with the clinical features and the histopathological changes occurring in the ruptured tendon and subacromial bursa of patients with rotator cuff tear. One hundred and eighty patients were clinically evaluated with the constant score and the visual analogue pain scale. Radiographs and MRI were performed. The chronology of the rupture, the muscle fatty degeneration according to Goutallier's scale and the tear size were evaluated. For each patient, a biopsy of the supraspinatus tendon and subacromial bursa was performed during arthroscopic rotator cuff tear repair and the specimens were histopathologically analysed. Clinically, the shoulder was more painful in females, in the presence of a chronic cuff lesion and a low Goutallier's grade (P rotator cuff tear. In particular, a greater association of pain was observed with the histopathological changes in the bursa compared with those in the rotator cuff. Considering that the bursa plays also an essential role during the healing process, this "new" role of the subacromial bursa as pain generator has important repercussions in both pharmacological and surgical treatments of rotator cuff tears.

    Here we describe clinicopathologic features of Ebola virus disease in pregnancy. One woman infected with Sudan virus in Gulu, Uganda, in 2000 had a stillbirth and survived, and another woman infected with Bundibugyo virus had a live birth with maternal and infant death in Isiro, the Democratic Republic of the Congo in 2012. Ebolavirus antigen was seen in the syncytiotrophoblast and placental maternal mononuclear cells by immunohistochemical analysis, and no antigen was seen in fetal placental stromal cells or fetal organs. In the Gulu case, ebolavirus antigen localized to malarial parasite pigment-laden macrophages. These data suggest that trophoblast infection may be a mechanism of transplacental ebolavirus transmission. Published by Oxford University Press for the Infectious Diseases Society of America 2016.

    Skeletal coccidioidomycosis is a rare complication of pulmonary coccidioidomycosis that remains incompletely characterized, and its histopathologic features have not been systematically evaluated. All skeletal coccidioidal infections (2000 to 2012) were retrieved from the University of Arizona and Mayo Clinic in Arizona pathology archives. Clinical history and histologic features were reviewed. Among 25 patients (median age 40 y; 17 men), infections involved bones (2 cases), joints (6), or both (17), usually in the distal extremities (68%), especially the wrist (32%). History included previously documented coccidioidomycosis (13), autoimmune disease (8), diabetes (6), malignancy (4), and iatrogenic immunosuppression (10). Common symptoms (median 3 mo) included pain/arthralgia (21) and swelling (10). Cultures and serology were positive in 15 of 17 (88%) and 19 of 22 patients (86%), respectively. Treatment included surgical debridement(s) and chronic antifungal medication(s). Histologic review showed granulomas in all cases, ranging from poorly to well formed, with or without necrosis. Spherule density varied widely (mean 4.8/HPF; range <0.1 to 13.5/HPF). Composition of inflammatory infiltrates, degree of necrosis, and extent of fibrosis did not significantly differ between immunocompetent and immunocompromised patients. Eosinophils were only seen in one third of cases; when present, eosinophils were almost always rare. 10 patients experienced recurrent infection, 8 of whom were immunocompromised; the remaining patients recovered. In conclusion, distal extremities are the most common sites of skeletal coccidioidomycosis encountered by surgical pathologists. This condition is strongly associated with autoimmune disorders and immunosuppression. Spherules are sometimes rare, and multiple modalities including serology, culture, and histology may be required for diagnosis.

    Full Text Available Background: The aim of our study was to investigate the clinical and histopathological characteristics of cutaneous leishmaniasis (CL in the city of Sanliurfa in Turkey, where Syrian refugees also reside. Materials and Methods: At the Harran University Hospital outpatient clinics between 2012 and 2013, 54 CL cases, including 24 Syrian patients, underwent punch biopsy of the skin and/or a touch imprint. Patients in whom leishmania parasites were detected were included in the study. The clinical and histopathological data of the patients were obtained by a review of the patients′ medical records. All the slides of each patient were re-evaluated histopathologically. Results: Fifty-four cases (mean age; 17 ± 12 years, consisting of 32 males (59.3% and 22 females (40.7%, were examined. The most common site of involvement was the face (63%. The most common presentation was noduloulcerative lesions (57.4%. Histopathologically, the majority of the cases exhibited hyperkeratosis, follicular plugging of the epidermis, chronic inflammatory infiltration, leishmania amastigotes and non-caseating granulomatous inflammation in the dermis. Conclusion: CL presents with a wide spectrum of expression, both clinically and histologically, and may mimic other inflammatory and neoplastic diseases. The diagnosis of CL relies on the identification of leishmania amastigotes in either a direct smear of the lesion or in a tissue section.

    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.

    Fifty-tree patients with localized painful spine syndrome were investigated prospectively by contrast-enhanced MRI. Pain was not predominantly radiating and there was no clinical evidence of spinal infection. In all patients, sagittal SE T1-weighted, fast-SE T2-weighted or turbo-STIR, and T1-weighted frequency-selective fat-suppressed images were obtained. We identified 37 vascularized disks in 26 patients. In 18 patients the changes had occurred spontaneously, in 6, the affected disk had been operated on previously, and 2 patients had spondylolisthesis. In 15 patients, vascularization was accompanied by medullary edema adjacent to the vertebral endplates. In one of the vascularized disks, herniation was also found. In seven patients, ventral diskectomy was performed. Histopathologic findings confirmed disk vascularization in six of seven cases. Degenerative, band-like disk vascularization is a feature which is associated with local pain. It is demonstrated by contrast-enhanced MRI. Degenerative disk vascularization is an important differential diagnosis to bacterial spondylodiskitis. It can be a cause of pain in patients with postdiskectomy syndrome. (orig./MG)

    Histopathological diagnoses have been done in the last century based on hematoxylin and eosin staining. These methods were complemented by histochemistry, electron microscopy, immunohistochemistry (IHC), and molecular techniques. Mass spectrometry (MS) methods allow the thorough examination of various biocompounds in extracts and tissue sections. Today, mass spectrometry imaging (MSI), and especially matrix-assisted laser desorption ionization (MALDI) imaging links classical histology and molecular analyses. Direct mapping is a major advantage of the combination of molecular profiling and imaging. MSI can be considered as a cutting edge approach for molecular detection of proteins, peptides, carbohydrates, lipids, and small molecules in tissues. This review covers the detection of various biomolecules in histopathological sections by MSI. Proteomic methods will be introduced into clinical histopathology within the next few years.

    Mixed gonadal dysgenesis (MGD) is an abnormality of sexual differentiation (ASD), which encompasses an heterogeneous group of different gonadal and phenotypic abnormalities. This study describes the main clinical features found in 16 patients with MGD, relating the clinical presentation with cytogenetic evaluation and histopathological findings. For purpose of this study, MGD was considered in those patients who fulfilled the following diagnostic criteria: 1) müllerian and/or wolfflan derivatives; 2) any of the following gonadal characteristics: a) bilateral intrabdominal or scrotal immature testicular tissue; b) intrabdominal or scrotal immature testicular tissue with contralateral streak gonad. Patients were selected from an ASD study which was carried out in Medical Genetic Unit of University of Zulia (UGM-LUZ), Maracaibo, Venezuela, from 1980 to 1997. The following information was extracted from the medical history at UGM-LUZ: age, gender which patient was reared, clinical presentation, cytogenetic evaluation, laparoscopic findings and gonadal biopsy. Sixteen patients fulfilled the diagnostic criteria and ranged in age from 1.2 to 39.4 years with an average of 12.65 years. Only 5 patients were reared as males. Twelve patients consulted for genital ambiguity. Chromosomal evaluation was as following: 8 patients with 45,X/46,XY mosaicism: 5 had a 46,XY normal male karyotype and the remaining patients: 46,XX; 46,XX/46,XY and 45,X/46,Xi(Xq) karyotypes, respectively. All patients showed müllerian derivatives and occasionally wolffian derivatives. Gonadal tumors were present in 2 patients. Molecular studies of genes that govern gonadal development are necessary for a better understanding of the wide heterogeneity present in MGD.

    Full Text Available Darier′s disease, also known as keratosis follicularis, is a rare autosomal dominant genodermatosis, manifesting clinically as hyperkeratotic, firm papule that predominates in the seborrheic areas and flexures with accompanying nail abnormalities. Heat, sweating, sunlight, and stress are exacerbating factors of the lesion. The oral lesions are asymptomatic and comprise multiple white papules in the buccal mucosa and hard palate, giving a cobblestone appearance, and it is characterized histologically by loss of desmosomal adhesion and abnormal keratinization resulting in mucocutaneous abnormalities. Pruritus, recurrent infections, and malodor can decrease the quality of life. We report a case of a 7-year-old boy with clinical and histological features of Darier′s disease.

    Melanoma of the oral cavity is a rare malignancy that carries a poor prognosis. We identified 46 new cases of both primary and metastatic melanoma to the oral cavity. Following IRB approval, these cases were obtained from the Oral Pathology Biopsy Service archives of the UF College of Dentistry (1994-2014), the UK College of Dentistry (1997-2015), and the UM Medical Center (1988-2015). All slides were reviewed. The location, age, race, gender, clinical impression, duration of lesion, histopathologic diagnosis, and histopathologic features were recorded. Cases from the facial skin and those with an ambiguous diagnosis were excluded. Forty-six cases fulfilled the inclusion criteria with 32 primary cases, 11 known metastases, and 3 cases where metastasis could not be excluded. The primary cases included a total of 20 females and 12 males with an average age of 66.7 (range 27-95), and the majority (80 %) of the patients were Caucasian when race was known. Twenty-two of the 32 primary cases (68.8 %) were located in the maxillary mucosa, 5 in the mandibular mucosa or bone, and 5 in other locations. The clinicians' impressions varied from benign fibrous growths to high grade malignancies. The histopathology varied widely among the cases, however two cell types predominated (often in combination): epithelioid cells (50.0 %) and spindle cells (50.0 %). Only 53.1 % demonstrated melanin pigmentation. Oral melanoma remains one of the most diverse clinical and histopathologic diagnoses. Better understanding of this neoplasm may promote earlier diagnosis and may lead to improved outcomes.

    Study of mass in ear was undertaken with the aim that clinical diagnosis was in most but not all cases consistent with the histo-pathological diagnosis. Therefore incisional or excisional biopsy with histo-pathological study is a must in all types of small masses in ear. A study of 50 patients, attending Ear, Nose and Throat department, was done and specimen collected from them and subjected to histopathological examination. These masses were further classified as inflammatory, benign and malignant lesions and the frequency of their occurrence in saurashtra region (Jamnagar, GUJARAT), their age and sex distribution were observed. Most common lesion was found to be inflammatory Polyps (20), followed by Cholesteatomas (12) and chronic non-specific inflammations (7), Abscess (1). In malignant lesions Squamous cell carcinoma (7) was the commonest followed by Embryonal rhabdomyosarcoma (1) and in benign lesion, Carcinoid tumor (1) and Nevus (1) were diagnosed on histo-pathological examination. Right side masses were more common than left side; males were more affected than females. Adolescents/children more affected than adults for benign lesions while reverse was true for malignant lesions.

    Rosacea is a chronic inflammatory skin condition that predominantly affects the central face. It is characterised by a variable range of symptoms, including erythema, telangiectasia, papules, pustules and changes in skin texture. Rosacea may be transient, recurrent or persistent. Because it affects the most visible part of the body, the psychosocial effects of this condition can be significant. This article describes the features and management of the condition.

    1998-06-01

    Legionnaires' disease is a systemic infectious disease primarily involving the lungs, with multisystemic extrapulmonary manifestations. Any species of Legionella may cause legionnaires' disease in normal and compromised hosts. The clinical diagnosis of legionnaires' disease may be made on the basis of associated extrapulmonary clinical and laboratory findings. Although no single finding in legionnaires' disease is pathognomonic, the association of key extrapulmonary constitutes a typical pattern that is diagnostically characteristic. The syndromic approach based on a weighted point evaluation system described in the article gives physicians a system to arrive at a rapid presumptive clinical diagnosis of legionnaires' disease. Definitive diagnosis of legionnaires' disease is by direct fluorescent antibody testing of respiratory specimens, serological methods, Legionella urinary antigenuria, or culture.

    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.

    Clinical, neurological, endoscopic, psychological findings, questionnaire data on vegetative sphere, diaphragm x-ray, articulation test and Viene test system evidence obtained on 25 patients with phonic spasm confirm organic neurological nature of spastic dysphonia as focal muscular dystonia. This condition can be accompanied with tremor, rotatory, winking and writers' spasms, oromandibular dystonia. As indicated by positive treatment outcomes, combined treatment of phonic spasm with GABA-ergic drugs of clonazepam (antelepsin) and baclofen, orthophonic voice correction, physiotherapy is pathogenetically justified.

    Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare lymphoma entity. We performed a matched-pair analysis to evaluate the prognostic impact of several histopathological features in this distinct Hodgkin lymphoma subtype. Lymph node samples of NLPHL patients were tested for CD15, IgD, phosphorylated STAT6, ICOS and Epstein-Barr virus status of the malignant lymphocyte-predominant cells as well as epithelioid cell clusters and activated T cells in the microenvironment. None of these features was associated with a particular clinical outcome. However, patients presenting with epithelioid cell clusters showed a non-significant trend towards a lower relapse rate, justifying further evaluation of this marker. © 2014 John Wiley & Sons Ltd.

    Full Text Available CONTEXT: Intestinal parasites induce detectable histopathological changes, which have been studied in groups with known diagnosis of parasitic disease. There is no available study with a larger base without previous diagnosis. OBJECTIVE: To describe clinical and histopathological findings of parasitosis diagnosed by endoscopic biopsy in patients submitted to upper digestive endoscopy. METHODS: Recorded biopsies archive at "Complexo Hospitalar Professor Edgar Santos" , a general teaching Hospital in the state of Bahia, Northeast Brazil, from January 1995 to January 2009, were reviewed. One thousand ten duodenal biopsy reports were found. Reports positive for parasites had their specimens reviewed and photographed. All blocks of biopsy selected as case were retrieved and reviewed by an experienced pathologist. Clinical, laboratorial and endoscopic data were collected. RESULTS: Eleven biopsies showed parasites, including cases of Cryptosporidium sp. and Strongyloides stercoralis. Vomiting (91%, abdominal pain (78%, diarrhea (78% and weight loss (78% were usual symptoms. Seventy-five percent had duodenal mucosa changes on endoscopy, while 25% have no changes. Anemia and low serum albumin were important laboratorial data. HIV infection association was observed. Villus atrophy and reactive epithelium were usual in Strongyloides cases. CONCLUSIONS: No endoscopic or histopathologic finding was pathognomonic. One percent of duodenal endoscopic biopsies showed parasites.

    2009-01-01

    Full Text Available Aluminium phosphide poisoning is very common in India. It is one of the most fatal poisons. The clinical spectrum of poisoning varies depending upon the dosage and duration of consumption. The main effect of the poison is due to the release of phosphine which inhibits cytochrome oxidase and thereby hampers cellular oxygen utilization. Almost any organ can be affected by aluminium phosphide poisoning. We report a case where the heart was the predominantly affected organ. We describe the clinical symptoms and signs and their correlation with electrocardiographic and histopathological examinations.

    Multilocular thymic cysts are rare and acquired lesions induced by an inflammatory arising within the thymus. We report a rare case of multilocular thymic cyst with follicular lymphoid hyperplasia in a 59-year-old female. Chest CT and MRI revealed a large multilocular cystic mass, which contains thick septa and nodules in the thymus. F-18 FDG PET/CT showed almost no FDG uptake of the multilocular cystic mass but moderate FDG uptake of the solid nodules. Extended total thymectomy was performed. Histopathological findings revealed follicular lymphoid hyperplasia of thymic tissue but no neoplastic lesion. Based on these findings, diagnosis of multilocular thymic cyst with follicular lymphoid hyperplasia was made. This is a rare case that preoperatively was difficult to diagnose.

    Full Text Available Objectives: Fine-needle aspiration biopsy (FNAB is thegold standard in the management of thyroid nodules andspecimen should be obtained from dominant nodule. Inour study, we aimed to compare the FNAB and histopathologyresults of dominant and non-dominant nodulesand to evaluate the association between nodule size andhistopathology results in patients with MNG.Materials and methods: Between 2009 and 2010, 197cases who had diagnosed MNG were analyzed. Thesecases were performed FNAB from both dominant noduleand non-dominant nodule. 26 patients with inadequatecytological results were excluded and 171 cases were includedin the analysis. Malignant ultrasonographic (USfeatures were defined as showing marked hypoechogenicity,microcalcifications, solid structure and not havingperipheral halo.Results: No statistically significant difference was observedbetween malign cytology and suspected cytologyratios of dominant nodules and non-dominant nodules(p=0.083. Malignancy rates were higher at dominantnodules not having peripheral halo and non-dominantnodules including microcalcification at US. Also statisticallysignificant difference was not observed (p=0.485between malign histopathology rates of dominant andnon-dominant nodules after surgery.Conclusions: According to cytological and histopathologicalresults of patients with MNG, there was no significantdifference between the malignancy ratio of dominantand non-dominant nodules. There is no obvious correlationbetween malignancy and nodule size in patients withMNG. We think that FNAB obtained not from only dominantnodules but also nodules with suspicious featuresof malignancy is necessary for most accurate diagnosis.

    According to Nottingham grading system, mitosis count plays a critical role in cancer diagnosis and grading. Manual counting of mitosis is tedious and subject to considerable inter- and intra-reader variations. The aim is to improve the accuracy of mitosis detection by selecting the color channels that better capture the statistical and morphological features, which classify mitosis from other objects. We propose a framework that includes comprehensive analysis of statistics and morphological features in selected channels of various color spaces that assist pathologists in mitosis detection. In candidate detection phase, we perform Laplacian of Gaussian, thresholding, morphology and active contour model on blue-ratio image to detect and segment candidates. In candidate classification phase, we extract a total of 143 features including morphological, first order and second order (texture) statistics features for each candidate in selected channels and finally classify using decision tree classifier. The proposed method has been evaluated on Mitosis Detection in Breast Cancer Histological Images (MITOS) dataset provided for an International Conference on Pattern Recognition 2012 contest and achieved 74% and 71% detection rate, 70% and 56% precision and 72% and 63% F-Measure on Aperio and Hamamatsu images, respectively. The proposed multi-channel features computation scheme uses fixed image scale and extracts nuclei features in selected channels of various color spaces. This simple but robust model has proven to be highly efficient in capturing multi-channels statistical features for mitosis detection, during the MITOS international benchmark. Indeed, the mitosis detection of critical importance in cancer diagnosis is a very challenging visual task. In future work, we plan to use color deconvolution as preprocessing and Hough transform or local extrema based candidate detection in order to reduce the number of candidates in mitosis and non-mitosis classes.

    Full Text Available The count of mitotic figures in Breast cancer histopathology slides is the most significant independent prognostic factor enabling determination of the proliferative activity of the tumor. In spite of the strict protocols followed, the mitotic counting activity suffers from subjectivity and considerable amount of observer variability despite being a laborious task. Interest in automated detection of mitotic figures has been rekindled with the advent of Whole Slide Scanners. Subsequently mitotic detection grand challenge contests have been held in recent years and several research methodologies developed by their participants. This paper proposes an efficient mitotic detection methodology for Hematoxylin and Eosin stained Breast cancer Histopathology Images using Gabor features and a Deep Belief Network- Deep Neural Network architecture (DBN-DNN. The proposed method has been evaluated on breast histopathology images from the publicly available dataset from MITOS contest held at the ICPR 2012 conference. It contains 226 mitoses annotated on 35 HPFs by several pathologists and 15 testing HPFs, yielding an F-measure of 0.74. In addition the said methodology was also tested on 3 slides from the MITOSIS- ATYPIA grand challenge held at the ICPR 2014 conference, an extension of MITOS containing 749 mitoses annotated on 1200 HPFs, by pathologists worldwide. This study has employed 3 slides (294 HPFs from the MITOS-ATYPIA training dataset in its evaluation and the results showed F-measures 0.65, 0.72and 0.74 for each slide. The proposed method is fast and computationally simple yet its accuracy and specificity is comparable to the best winning methods of the aforementioned grand challenges

    Dentinogenesis imperfecta (DI) type II, an inherited disorder affecting dentin, has been linked to mutations in the dentin sialophosphoprotein ( DSPP) gene on chromosome 4q21. The gene product is cleaved into two dentin-specific matrix proteins, dentin sialoprotein (DSP) and dentin phosphoprotein. The aim of this investigation was to study genotypes and phenotypes in two affected families with special reference to clinical, radiographic, and histopathologic manifestations. Seven affected members of Family A and five of Family B were documented clinically and radiographically; 14 and 10 teeth, respectively, were available for histopathologic investigation and prepared for ground sections, which were assessed semiquantitatively for dysplastic manifestations in the dentin according to the scoring system, dysplastic dentin score (DDS). Venous blood samples were collected from six affected and ten unaffected members of Family A, and from eight affected and six unaffected members of Family B. Genomic DNA was extracted and used for sequence analyses. The two families presented with different missense mutations. An Arg68Trp missense mutation in the DSP part of the gene was revealed in all six analyzed affected individuals in Family A. This mutation was not present in any of the ten healthy members. In Family B, an Ala15Val missense mutation involving the last residue of the signal peptide was found in all eight affected but in none of the six healthy members. The clinical and radiographic disturbances and DDS were more severe in Family B. The data indicate the presence of a genotype-phenotype correlation in DI type II.

    The objective of this paper is to provide an improved technique, which can assist oncopathologists in correct screening of oral precancerous conditions specially oral submucous fibrosis (OSF) with significant accuracy on the basis of collagen fibres in the sub-epithelial connective tissue. The proposed scheme is composed of collagen fibres segmentation, its textural feature extraction and selection, screening perfomance enhancement under Gaussian transformation and finally classification. In this study, collagen fibres are segmented on R,G,B color channels using back-probagation neural network from 60 normal and 59 OSF histological images followed by histogram specification for reducing the stain intensity variation. Henceforth, textural features of collgen area are extracted using fractal approaches viz., differential box counting and brownian motion curve . Feature selection is done using Kullback-Leibler (KL) divergence criterion and the screening performance is evaluated based on various statistical tests to conform Gaussian nature. Here, the screening performance is enhanced under Gaussian transformation of the non-Gaussian features using hybrid distribution. Moreover, the routine screening is designed based on two statistical classifiers viz., Bayesian classification and support vector machines (SVM) to classify normal and OSF. It is observed that SVM with linear kernel function provides better classification accuracy (91.64%) as compared to Bayesian classifier. The addition of fractal features of collagen under Gaussian transformation improves Bayesian classifier's performance from 80.69% to 90.75%. Results are here studied and discussed.

    Full Text Available Context: The spectrum of pediatric renal tumors is different from adult renal tumors, and Wilms′ tumor (WT forms the majority. The histological type and clinicopathological staging are the two important prognostic parameters. The role of newer prognostic factors is not clear. Aims: This study was performed to analyze the histopathological spectrum of pediatric renal tumors and to study the expression of proliferation markers (Ki-67 and p53 in WT and correlate its expression in epithelial and blastema components in different stages. Materials and Methods: Twenty-seven cases of pediatric renal tumors were collected over 2 years. Hematoxylin-eosin staining was used for diagnosis. Immunostaining was performed for Ki-67 and p53. Ki-67 proliferation index (PI and p53 expression were determined in each case and for the epithelial and blastema components separately. Statistical Analysis and Results: We had 20 cases of WT (74.1%, three cases of mesoblastic nephroma (11.1%, three cases of clear cell sarcoma (11.1% and one case of rhabdoid tumor (3.7%. It was observed that the PI of the epithelial component (57.2% was significantly higher than that of blastema (39.53% in all stages. The PI in Stage II is significantly higher than that in Stage I. Statistical analysis could not be performed in Stages III and IV due to the small number of cases. p53 expression did not show any significant difference in the epithelial and blastema components. There was also no significant difference between the stages. Conclusion: In this study, we found the differences between PI of different tissue components of WT, with the epithelial component having a higher PI, which correlated with the stage of advancement of the disease.

    Leprosy, a relatively common chronic contagious disease having diverse modes of clinical presentation, can mimic a variety of unrelated diseases. For proper and adequate treatment, the diagnosis must be made accurately with subtyping which should be done with the help of bacillary index, histopathological features, and clinical correlation. This is extremely important in patient care as paucibacillary and multibacillary types have different modes of treatment. Our aim is to categorize leprosy into various types based on bacillary index, morphological findings both in slit skin smears, and biopsy along with clinical correlation.

    Colorectal cancer is the second leading cause of cancer deaths in the United States, affecting more than 130,000 Americans every year(1). Determining tumor margins prior to surgical resection is essential to providing optimal treatment and reducing recurrence rates. Colorectal cancer recurrence can occur in up to 20% of cases, commonly within three years after curative treatment. Typically, when colorectal cancers are resected, a margin of normal tissue on both sides of the tumor is required. The minimum margin required for colon cancer is 5 cm and for the lower rectum 2 cm. However, usually more normal tissue is taken on both sides of the tumor because the blood supply to the entire segment is removed with the surgery and therefore the entire segment must be removed. Anastomotic recurrences may result from inadequate margins. Pathologists look at the margins to ensure that there is no residual tumor and this is usually documented in the pathology report. We have developed a portable, point-of-care fiber bundle microendoscopy imaging system for detection of abnormalities in colonic epithelial microstructure. The system comprises a laptop, a modified fiber bundle image guide with a 1mm active area diameter and custom Lab VIEW interface, and is approved for imaging surgically resected colon tissue at the University of Arkansas for Medical Sciences. The microendoscopy probe provides high-resolution images of superficial epithelial histology in real-time to assist surgical guidance and to localize occult regions of dysplasia which may not be visible. Microendoscopy images of freshly resected human colonic epithelium were acquired using the microendoscopy device and subsequently mosaicked using custom post-processing software. Architectural changes in the glands were mapped to histopathology H&E slides taken from the precise location of the microendoscopy images. Qualitatively, glandular distortion and placement of image guide was used to map normal and dysplastic areas

    Full Text Available To study clinical and histopathological changes occur within the first 12 hours of strangulating obstruction of the small intestine in equine, twenty five adult donkeys were used in an experimental study. Strangulation obstruction of the small intestine was performed for 3, 6, 9 and 12 hours, respectively. Clinical examination was done before surgery and at 3 hours intervals postoperatively. After euthanasia, histopathological examination was made 10 cm, 1, 2 and 3 meters proximal to the strangulated part. Three hours postoperatively, the animals began to show signs of abdominal pain, they were looking around, stamping the hind feet, falling down suddenly. Nine hours postoperatively, animals showed signs of depression with intermittent nervous movements in the form of circle movement. After 12 hours, the animals were lying down; There were a significant reduction in the body temperature, respiratory rate, pulse rate, heart rate with significant increase in capillary refill time. Macroscopic changes of the strangulated part were congestion, edema, and dark red discoloration of the intestinal wall and mesentery. Distension of the intestine proximal to the strangulation extended more with increase the period of strangulation. Microscopic examination showed showed severe congestion, dark brown to blackish discoloration with fibrous shreds on the strangulated segment. Peticheal hemorrhages were observed in the intestinal wall and its mesentery for a distance up to 3 meters. The severity of signs varies according to the duration of obstruction which could give a remarkable justification of the prognosis of the patient and the availability of treatment.

    The purpose of this study was to compare clinical, radiographic, and histopathologic effects of Nd:YAG laser pulpotomy to formocresol pulpotomy on human primary teeth. Patients with at least two vital primary molar teeth that required pulpotomy, because of pulpal exposure to caries, were selected for this study. After hemorrhage control, complete hemostasis into the canal orifice was achieved by exposure to Nd:YAG laser (1064 nm) and an He-Ne laser (the aiming beam of the Nd:YAG laser) in noncontact mode at 2 W, 20 Hz, 100 mJ, or was achieved by applying 1:5 dilution of formocresol. Forty-two teeth in two groups were to be followed up clinically and radiographic at 1, 3, 6, 9, and 12 months. Eighteen teeth planned for serial extractions were selected for histopathologic study. The teeth were extracted at 7 and 60 days. The teeth in the laser group had a clinical success rate of 85.71% and a radiographic success rate 71.42% at 12 months. The teeth in the formocresol group had a clinical and radiographic success rate of 90.47% at 12 months. There were no statistically significant differences between laser and formocresol group with regard to both clinical and radiographic success rates. There was a statistically significant difference between 7- and 60-day laser groups with regard to inflammatory cell response criteria. Dentin bridge was absent in all samples. No stained bacteria were observed in any of these samples. In conclusion, Nd:YAG laser may be considered as an alternative to formocresol for pulpotomies in primary teeth.

    Summary: The MRI appearances of 7 adult patients with pathologically proven intracranial primitive neuroectodermal tumors (PNET) were retrospectively analyzed. The MRI features were compared with findings in pathology and surgery. In this group, the tumor masses were most commonly found in the semisphere of cerebrum and in the vermis of cerebellum. They were relatively large and 4 were in lobulated shape. All of them had well-defined margins. MR images showed the tumors to be mildly or obviously hypointense on Ti-weighted images and hyperintense on T2-weighted images. Most masses had heterogeneous appearances with some cystic and necrotic areas. Intratumoral haemorrhage and focal calcification were occasionally seen. Mostly, there was no or only mild surrounding edema. Marked inhomogeneous contrast enhancement on MRI was seen in 6 cases except one. Two patients with multiple intracranial metastases were revealed on MR images. In this series, there was good correlation between MRI features and findings in pathology and surgery.These results showed that certain MRI features might suggest the diagnosis of intracranial PNET in adults. MRI is an effective technique to detect these tumors and is helpful to treatment planning and follow-up.

    Full Text Available BACKGROUND: Plaque disruption with superimposed thrombus is the predominant mechanism responsible for the onset of acute coronary syndromes. Studies have shown that plaque disruption and thrombotic occlusion are frequently separated in time. We established the histopathological characteristics of material aspirated during primary percutaneous coronary intervention (PCI in a large consecutive ST-elevation myocardial infarction (STEMI population. METHODOLOGY/PRINCIPAL FINDINGS: Thrombus aspiration during primary PCI was performed in 1,362 STEMI patients. Thrombus age was classified as fresh (5 day. Further, the presence of plaque was documented. The histopathological findings were related to the clinical, angiographic, and procedural characteristics. Material could be aspirated in 1,009 patients (74%. Components of plaque were found in 395 of these patients (39%. Fresh thrombus was found in 577 of 959 patients (60% compared to 382 patients (40% with lytic or organized thrombi. Distal embolization was present in 21% of patients with lytic thrombus compared to 12% and 15% of patients with fresh or organized thrombus. CONCLUSIONS/SIGNIFICANCE: Material could be obtained in 74% of STEMI patients treated with thrombus aspiration during primary PCI. In 40% of patients thrombus age is older than 24 h, indicating that plaque disruption and thrombus formation occur significantly earlier than the onset of symptoms in many patients.

    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.

    Twelve cases of Mucolipidosis II (I-cell disease) with a wide range of severity of skeletal involvement were studied. Pathological findings in two cases provided helpful information in understanding the radiographic features of dysostosis multiplex. Inhibition of the growth plate cartilage calcification and rickets-like lesions were observed in the metahphyses. Enhanced subperiosteal remodelling and paratrabecular fibrosis were also evident in the diaphyses. High levels of parathormone were found in one case. This finding supports the hyporthesis that bone lesions may be secondary, at least in part to damage in such viscera as the kidney and/or the liver and that they are mediated by vitamin D and parathormone.

    A previous report suggests a substantial incidence of exertional rhabdomyolysis (ER) in Arabian horses performing endurance racing. This study compared formalin histopathology and clinical and metabolic responses to a standardised field exercise test (SET) between Arabians with and without ER. Arabian horses with (n = 10; age 15.4 ± 5.6 years) and without (n = 9; 12.9 ± 6.1 years) prior ER were stall-rested for 24-48 h, after which paired ER and control horses were fitted with a telemetric ECG and performed a 47 min submaximal SET. Plasma glucose, lactate, electrolyte and total protein concentrations and packed cell volume were measured before and immediately after exercise. Blood and percutaneous gluteal muscle samples were also obtained before and 3 h after exercise for measurement of plasma creatine kinase (CK) activity and muscle glycogen concentration, respectively. Histopathologic analysis of formalin-fixed pre-exercise muscle sections was performed. Data were analyzed by ANOVA and non-parametric tests (P exercise, and plasma CK increased similarly in ER and control Arabians. Muscle glycogen, heart rate, and remaining plasma variables did not differ between horses with ER and control horses. Horses with ER had more internalised nuclei in mature myofibers, more aggregates of cytoplasmic glycogen and desmin, and higher myopathic scores than control horses. Although many horses with ER had histopathologic evidence of chronic myopathy, muscle glycogen concentrations and metabolic exercise responses were normal. Results did not support a consistent metabolic myopathy or a glycogen storage disorder in Arabians with ER.

    Mutations in ryanodine receptor 1 gene (RYR1) are frequent causes of myopathies. They classically present with central core disease; however, clinical variability and histopathologic overlap are being increasingly recognized. Patient 1 is a 15-year-old girl with mild proximal, four-limb weakness from age 5, presenting with a progressive scoliosis starting at age 10. Patient 2 is an 18-year-old girl with progressively worsening muscle hypotrophy and mild proximal, four-limb weakness. She developed a rapidly progressive scoliosis from age 11 and needed surgical treatment at age 14 years. Patient 3 is an 11-year-old boy with moderate proximal limb weakness and progressive neck flexor weakness, first noticed at age 2. Muscle biopsies revealed type 1 fiber predominance (Patients 1 and 2) or abnormal type 1 fiber uniformity (Patient 3). Different RYR1 variants were identified in all patients. In Patients 1 and 3, these changes were validated as being pathogenic. These patients illustrate early-onset, progressive myopathies with predominant axial involvement. Histopathologic findings were abnormal but not specific for a diagnosis, particularly central core myopathy. Genetic testing helped broaden the range of phenotypes included in the RYR1-related myopathies. Our patients reinforce the need to recognize the broad histopathologic variability of RYR1-related myopathies and sometimes lack of pathognomonic findings that may reduce the diagnostic threshold of this disease. We suggest that the predominance of type 1 fibers and involvement of axial muscles may be an important element to consider the RYR1 gene as candidate. Copyright © 2014 Elsevier Inc.

    Objective: To study the CT characteristics of solitary focal organizing pneumonia (FOP). Materials and methods: Chest CT of consecutive 45 patients (34 males and 11 females, median age: 56 years) with confirmed FOP were analyzed. The CT features between large FOP (>3 cm, n = 27) and small FOP (≤3 cm, n = 18) were compared. Results: FOP lesions predominately located in peripheral lungs (86.7%), with the right lower lobe being most common lobe (44.4%). No lesion mainly located in the inner 1/3 of lungs. All large lesions were polygon in shape and had an irregular margin, while small lesions were more likely to be round or oval with an irregular or smooth border. Air bronchogram or small bubble-like lucency was present in majority of the lesions. 42.2% of lesions had incompact internal structure with inhomogeneous density besides air component. Most lesions were associated with a contraction or convergence of surrounding vessels; while no pulmonary vessel was interrupted abruptly by a small FOP lesion. Majority of large lesions had broad contact with the pleura, while only one patient had mild pleural effusion. Mild mediastinal lymph nodes enlargement was present in about 1/5 of the patients. Conclusion: Compared with the known CT features of lung cancer, our results suggest differential diagnosis can often be made for large FOP, while small FOP may resemble lung cancer.

    Background 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. Objectives 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. Methods 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. Results 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. Conclusions 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. PMID:24162472

    Episodic ataxia (EA) is a clinically heterogeneous group of disorders that are characterized by recurrent spells of truncal ataxia and incoordination lasting minutes to hours. Most have an autosomal dominant inheritance pattern. To date, 8 subtypes have been defined according to clinical and genetic characteristics, and five genes are known to be linked to EAs. Both EA1 and EA2, which are caused by mutations in KCNA1 and CACNA1A, account for the majority of EA, but many patients with no identified mutations still exhibit EA-like clinical features. Furthermore, genetically confirmed EAs have mostly been identified in Caucasian families. In this article, we review the current knowledge on the clinical and genetic characteristics of EAs. Additionally, we summarize the phenotypic features of the genetically confirmed EA2 families in Korea. PMID:27667184

    D.C. Gomes Júnior

    Full Text Available ABSTRACT The purpose of this study was to evaluate acrylonitrile butadiene styrene (ABS and polyamide implants in rabbits submitted to evisceration at the macroscopic and microstructure level and to assess clinical response and histopathological changes as well. For the experimental study implants of 12mm diameter were prepared by rapid prototyping, weighed and the outer and inner surfaces evaluated macroscopically and by electron microscopy. In addition, a compression test was performed and ultrastructural damage was then determined. After evisceration of the left eyeball, nine New Zealand rabbits received ABS implants and nine others received polyamide implants. The animals were assessed daily for 15 days after surgery and every seven days until the end of the study (90 days. Histopathological evaluation was performed at 15, 45 and 90 days after surgery. The ABS implants weighed approximately 0.44g, while the polyamide ones weighed 0.61g. Scanning electron microscopy demonstrated that the ABS implants had regular-sized, equidistant micropores, while the polyamide ones showed micropores of various sizes. The force required to fracture the ABS implant was 14.39 ±0.60 Mpa, while for the polyamide one, it was 16.80 ±1.05 Mpa. Fifteen days after surgery, we observed centripetal tissue infiltration and scarce inflammatory infiltrate. Implants may be used in the filling of anophthalmic cavities, because they are inert, biocompatible and allow tissue integration.

    Cutaneous lesions of feline sporotrichosis show high fungal load and are associated with severe disease and elevated zoonotic potential. The present study describes the histopathology and fungal load of the lesions in different clinical presentations of feline sporotrichosis. Cats with sporotrichosis were separated into groups L1, L2 and L3 (lesions in one, two and three or more locations, respectively) and subjected to skin biopsies for histopathology. Eighty-six cats were included in the study. Lesions were suppurative granulomatous in 84 cases and poorly formed granulomas were predominant. The well-formed granulomas were associated with group L1. The high fungal load was predominant in group L3 and in poorly formed granuloma cases and did not occur in well-formed granulomas cases. The good general condition was associated with low fungal load. These findings suggest that the fungal load control in animals with more localized lesions and well-organized response is linked with the improvement in the outcome of infected cats.

    Objective: To present the histopathological and clinical correlation of mycetoma among patients attending King Abdulaziz University Hospital between 1998-2013.Methods: The data of all histopathologically diagnosed mycetomas in the period between January 1998 and January 2013 were collected through a computerized database search of the anatomic pathology archives at King Abdulaziz University Hospital. The collected data were analysed. Identification of species were performed for five patients using 16 S ribosomal DNA and internal transcribed spacer 2.Results: There were 19 patients with mycetoma with an average age of 44.26 years and male: female ratio of 4:1. Actinomycetoma were 63.15% and eumycetoma were 36.84%. All patients presented with the classic lesions; presenting as painless subcutaneous mass, sinuses and discharge containing grains. The swellings were of slow evolution, with preferential foot localization. Species specification performed for samples from five patients with active lesions revealed species of Actinomyces israelii and Madurella mycetomatis in respective cases.Conclusions: Actinomycetoma is more common than eumycetoma in this region. The fact that one of the patients with eumycetoma was a Saudi national raises the possibility of an indigenous species similar to Maduraella mycetomatis to be further explored for characteristics and pathogenesis. The disease has to be prioritized again and more robust and quick molecular diagnostic tools should be made available in order to save patients form disfiguring amputations.

    To explore the clinical features of hypokalemic periodic paralysis, and compare clinical features of primary group with those of thyrotoxicosis secondary group. Clinical data of 44 patients with hypokalemic periodic paralysis in Peking University First Hospital from 1996 December to 2008 December were retrospectively analyzed. There were 22 patients in primary group, and 22 in thyrotoxicosis group. Identical clinical features of both the groups: (1)It had a predilection in young men. (2)Main symptoms were limb movement disorder and fatigue, and paralysis recurrent attacked in most patients. (3) 40.9% to 68.2% patients had obvious incentives, and the common ones were a heavy meal, sweet drinks, or strenuous exercise. (4) Serum potassium levels of the two groups were obviously lower than the normal range. (5)In 20% patients of primary group and 25% patients of thyrotoxicosis secondary group, CK levels were higher than normal, while LDH and HBDH levels were normal. (6)The doses of potassium replishment were not correlated to serum potassium levels at the onset. Different clinical features of the two groups: (1) Patients of thyrotoxicosis group had hypermetabolism symptoms and thyroid dysfunction. Patients of primary group had no hypermetabolism symptoms, and all of them were euthyroid. (2)Serum potassium levels of thyrotoxicosis secondary group were lower than those of primary group significantly [(2.25 +/- 0.67) vs (2.78 +/- 0.49) mmol/L, P=0.007]. (3) Hyperkalemia is easier than primary group to rebound in thyrotoxicosis secondary group, after replenishment of potassium. Hypokalemic periodic paralysis has its clinical features, and patients with early diagnosis and replenishment of potassium in time have good prognosis. The doses of potassium replenishment are not determined by serum potassium levels at the onset. Hyperkalemia is easier to rebound in thyrotoxicosis secondary group after replenishment of potassium, serum potassium levels should be monitored closely

  5. Behavioral, medical imaging and histopathological features of a new rat model of bone cancer pain.

    Full Text Available Pre-clinical bone cancer pain models mimicking the human condition are required to respond to clinical realities. Breast or prostate cancer patients coping with bone metastases experience intractable pain, which affects their quality of life. Advanced monitoring is thus required to clarify bone cancer pain mechanisms and refine treatments. In our model of rat femoral mammary carcinoma MRMT-1 cell implantation, pain onset and tumor growth were monitored for 21 days. The surgical procedure performed without arthrotomy allowed recording of incidental pain in free-moving rats. Along with the gradual development of mechanical allodynia and hyperalgesia, behavioral signs of ambulatory pain were detected at day 14 by using a dynamic weight-bearing apparatus. Osteopenia was revealed from day 14 concomitantly with disorganization of the trabecular architecture (µCT. Bone metastases were visualized as early as day 8 by MRI (T(1-Gd-DTPA before pain detection. PET (Na(18F co-registration revealed intra-osseous activity, as determined by anatomical superimposition over MRI in accordance with osteoclastic hyperactivity (TRAP staining. Pain and bone destruction were aggravated with time. Bone remodeling was accompanied by c-Fos (spinal and ATF3 (DRG neuronal activation, sustained by astrocyte (GFAP and microglia (Iba1 reactivity in lumbar spinal cord. Our animal model demonstrates the importance of simultaneously recording pain and tumor progression and will allow us to better characterize therapeutic strategies in the future.

    Full Text Available Background: Adenomyosis is a very real problem encountered in modern gynecology due to the increase in the incidence, severity of the disease, and absence of effective methods of conservative treatment. The aim of the study was to investigate the clinical and morphological features of the focal and diffuse forms of adenomyosis. Methods and Results: The study involved 70 women who applied to the Center with the diagnosis of ‘adenomyosis’. Examination included transvaginal sonography (TVS, magnetic resonance spectroscopy (MRS, and morphological study of the adenomyotic foci. With a probability of 99%, one can argue that focal adenomyosis (FA in its clinical features is different from diffuse adenomyosis (DA in all its major manifestations. Conclusion: FA has unique morphological characteristics and clinical features. The diagnosis of FA should be based on a complex of clinical and instrumental data in conjunction with morphological process verification. Besides, there are difficulties in the diagnosis of FA, which is a major reason for the incorrect determination of the treatment tactic for patients. However, the application of MRS allows the preoperative identification of the biochemical structure of the focus and determination of its borders, and in the postoperative period, selection of optimal treatment tactics based on the identified morphological features of the removed adenomyotic foci.

    The objective of this study was to characterize the clinical, clinicopathological, and histopathological findings of dogs with chronic pancreatitis. The necropsy database at Texas A&M University was searched for reports of dogs with histological evidence of chronic pancreatitis defined as irreversible histologic changes of the pancreas (i.e. fibrosis or atrophy). A reference necropsy population of 100 randomly selected dogs was used for signalment and concurrent disease comparisons. Cases were categorized as clinical or incidental chronic pancreatitis based on the presence of vomiting, decreased appetite, or both vs. neither of these signs. All archived pancreas samples were scored histologically using a published scoring system. Sixty-one dogs with chronic pancreatitis were included. The most frequent clinical signs were lethargy, decreased appetite, vomiting, and diarrhea. Compared to the reference necropsy population, chronic pancreatitis cases were more likely to be older, neutered, of the non-sporting/toy breed group, and to have concurrent endocrine, hepatobiliary, or neurological disease. Clinical cases had significantly higher histological scores for pancreatic necrosis and peripancreatic fat necrosis, and were significantly more likely to have hepatobiliary or endocrine disease as well as increased liver enzyme activities, or elevated cholesterol and bilirubin concentrations. In conclusion, clinical disease resulting from chronic pancreatitis might be related to the presence of pancreatic necrosis and pancreatic fat necrosis. The signalment, presentation, and concurrent diseases of dogs with chronic pancreatitis are similar to those previously reported for dogs with acute pancreatitis.

    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.

    Full Text Available An outbreak of Marek’s disease was reported to occur in broiler chicken in Districts of Tasikmalaya and Ciamis. A total number of 58 tissues samples of broiler chicken were collected from 7 flocks of commercial broiler chicken farms in both Districts. The disease affected broiler chicken aged 17 to 24 days. Those chickens had been vaccinated to Newcastle Disease (ND and at age of 10 days had been vaccinated to Gumboro using blended bursa of fabricius. Tissue samples were fixed in 10% of buffered neutral formalin (BNF prior to haematoxilin and eosin (H and E stain using standard procedures. Histopathological features show that out of 58 samples, 32 (55.2% were infected by Marek’s Disease (19.0% were infected by Marek’s Disease, 20.1% were infected by Marek’s Disease and Gumboro, 16.1% Marek’s Disease and other infections, whereas 44.8% were infected by Gumboro alone or accompanied by other infections, ND and Colibasillosis. The study reveals that Marek’s Disease infection in broiler chicken tends to be mild i.e. infiltration of neoplastic cells (lymphoid, pleomorphic in proventriculus, intestine, spleen, livers and bursa of fabricius. In addition to this, there were mild non-supurative inflammation in heart, lung, peripheral nerve and brain, as well as a severe demyelination in brain. It is concluded that the histopthological features confirm the diagnosis of Marek’s Disease.

    The incidence of health problems associated with endocrine-disruption have increased. Many studies suggesting that endocrine disruptor chemicals (EDC) do contribute to cancer through estrogen-related receptors. Many chemicals have EDCs properties including insecticides. Early life exposure to EDCs can increased the risk of testicular cancer have been reported in the last decade. This study was aimed to determine the effect of insecticides exposure on histopathological tumor cell development of germ and Leydig cell. True experiment research design with posttest only control group design was applied. Sprague Dawley (SD) rat (n = 25) were randomly divided into 5 groups (control group, 25 mg β estradiol 3-benzoate, spiral mosquito coil repellent, 3 ml of liquid mosquito repellent, and 4 ml of liquid mosquito repellent). The exposure were administered for 20 days started at aged 3 days. At the age of 100 days (older adult), testis was stained using Hematoxyllin Eosin (HE) and histological features predicting malignancy were observed. The number of tumor cell development in both testicular germ cells and Leydig cells significantly increased in all treated group compared to those of control and the changes towards malignancy were also observed in all treated group. Exposure to mosquito insecticides causes significant changes in testicular germ and Leydig cell histological features that leads to malignancy.

    1. Systemic listeriosis was induced in 14-d-old Chukar partridge chicks, Alectoris chukar, by intravenous injection of a suspension containing 10(6) cfu/ml of viable Listeria monocytogenes organisms to study the course of infection. 2. Septicaemic and encephalitic forms of listeriosis were observed in all birds. Infection resulted in a fever response 8-h post-inoculation. Disease rapidly developed over a 24-h period with decreased activity, lethargy, ruffled feathers, huddling, listlessness, inability to stand, wing droop, decreased feed and water consumption, growth depression, neural disturbances and finally death. Gross and histopathological changes were observed in the myocardium, proventriculus, gizzard, intestine, pancreas, kidney, liver, spleen, lung, meninges and joints. 3. The diversity of these clinical signs and lesions suggests a high susceptibility of Chukar partridge chicks to systemic listeriosis.

    2012-01-01

    Full Text Available An 8-year-old male pug with a 12-month history of a progressive nonpainful mass on the left cornea was evaluated. Ocular examination showed a severe bilateral keratoconjunctivitis sicca, pigmentary keratitis, and an exophytic irregular pink mass occupying approximately 75% of the total corneal surface of the left eye. A squamous cell carcinoma (SCC was suspected on cytology, and clinical investigations showed no evidence of metastases. A transpalpebral enucleation was therefore performed, and the diagnosis of SCC was confirmed on histopathology. Immunohistochemical investigations showed that the neoplastic cells were pan-cytokeratin positive and vimentin negative. Additionally, nuclei immunoreactive to Ki-67 antigen were detected. Tumor cells were also negative to p53. Immunoreactivity to COX-2 was found in less than 10% of the neoplastic cells. No adjuvant therapies were instituted, and no evidence of local recurrence or distance metastasis was identified during the 24-month follow-up period.

    Aim: To evaluate the efficacy of Ultrasonography compared to clinical diagnosis, radiography and histopathological findings in the diagnosis of maxillofacial swellings. Material and methods: The study was conducted on forty-five patients with maxillofacial swellings. The clinical diagnosis, radiographic diagnosis and ultrasonographic diagnosis were made which was compared to the histopathological diagnosis. The maxillofacial swellings included cystic lesions, benign swellings, malignant swellings, lymphadenopathies and abscesses and space infections. Results: The diagnostic accuracy and contingency coefficient was evaluated considering histopathology as gold standard. The diagnostic accuracy of ultrasound was found to be 92.30% in the diagnosis of cystic lesions, 87.5% in benign tumors, 81.8% in malignant tumors, 100% in lymphadenopathies and 90% in space infections and abscesses. The contingency coefficient of 0.934 was obtained when ultrasonography was compared to the histopathology, which was highly significant. Similar significant results were obtained comparing ultrasonography with clinical diagnosis (0.895) and radiographic diagnosis (0.889). Conclusion: Ultrasonography provides accurate imaging of the head and neck region and provides information about the nature of the lesion, its extent, and relationship with the surrounding structures. As the conventional and digital radiography enable the diagnosis of the presence of the disease, but do not give any indication of its nature. So, together with clinical and histopathological examinations, real time ultrasound imaging works out as a valuable adjunct in the diagnosis of orofacial swellings.

    Prostate cancer is the sixth leading cause of cancer-related deaths in Japan. We aimed to elucidate the clinical and histopathological characteristics of patients with prostate cancer in the BioBank Japan (BBJ) project. Four thousand, seven hundred and ninety-three patients diagnosed with prostate cancer in the BBJ project were included. Clinical and histopathological data, including causes of death, were analyzed. Relative survival (RS) rates of prostate cancer were calculated. Four thousand, one hundred and seventy-one prostate cancer patients with available histological data had adenocarcinoma. The mean age of the patients was 72.5 years. The proportion of patients who were non-smokers, non-drinkers, had a normal body mass index, did not exercise, had a normal prostate-specific antigen level, and had a family history of prostate cancer were 30.7%, 28.0%, 66.6%, 58.1%, 67.6%, and 6.5%, respectively. The proportion of patients with Stage II, III, and IV disease were 24.4%, 7.3%, and 4.4%, respectively. After limiting to patients with a time from the initial diagnosis of prostate cancer to entry into the study cohort of ≤90 days (n = 869), the 5- and 10-year RS rates were 96.3% and 100.5%, respectively, although we were unable to consider management strategies due to a plenty of data missing. We provide an overview of patients with prostate cancer in the BBJ project. Our findings, coupled with those from various high throughput "omics" technologies, will contribute to the implementation of prevention interventions and medical management of prostate cancer patients.

    Several classification schemes have been developed for anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), with actual debate focusing on their clinical and prognostic performance. Sixty-two patients with renal biopsy-proven AAV from a single center in Mexico City diagnosed between 2004 and 2013 were analyzed and classified under clinical (granulomatosis with polyangiitis [GPA], microscopic polyangiitis [MPA], renal limited vasculitis [RLV]), serological (proteinase 3 anti-neutrophil cytoplasmic antibodies [PR3-ANCA], myeloperoxidase anti-neutrophil cytoplasmic antibodies [MPO-ANCA], ANCA negative), and histopathological (focal, crescenteric, mixed-type, sclerosing) categories. Clinical presentation parameters were compared at baseline between classification groups, and the predictive value of different classification categories for disease and renal remission, relapse, renal, and patient survival was analyzed. Serological classification predicted relapse rate (PR3-ANCA hazard ratio for relapse 2.93, 1.20-7.17, p = 0.019). There were no differences in disease or renal remission, renal, or patient survival between clinical and serological categories. Histopathological classification predicted response to therapy, with a poorer renal remission rate for sclerosing group and those with less than 25 % normal glomeruli; in addition, it adequately delimited 24-month glomerular filtration rate (eGFR) evolution, but it did not predict renal nor patient survival. On multivariate models, renal replacement therapy (RRT) requirement (HR 8.07, CI 1.75-37.4, p = 0.008) and proteinuria (HR 1.49, CI 1.03-2.14, p = 0.034) at presentation predicted renal survival, while age (HR 1.10, CI 1.01-1.21, p = 0.041) and infective events during the induction phase (HR 4.72, 1.01-22.1, p = 0.049) negatively influenced patient survival. At present, ANCA-based serological classification may predict AAV relapses, but neither clinical nor serological

    Full Text Available The authors present a report of a 44-year-old female patient, with complaints of visual disturbances in the left eye. The symptoms were present for at least 5 years and worsened in the last 2 years, impairing her activities. The patient reported perception of a floating circle, which blurred her vision. There was no previous history of trauma, infectious or inflammatory disease. Clinical evaluation included physical examination, laboratory testing, abdominal ultrasonography, thorax X-ray and head tomography. Ophthalmologic examination consisted of visual acuity, motility tests, biomicroscopy, tonometry and indirect ophthalmoscopy. Complementary investigation was done with a and b scan ocular ultrasonography. The chosen therapeutic approach to excise the cyst was pars plana vitrectomy, successfully performed. Anatomopathologic analysis revealed a pigmented vitreous cyst, of possible congenital origin, described as a cystic choristoma from the primitive hyaloid system. Benign evolution, clinical findings and histopathological analysis corroborated the diagnostic hypothesis of a cystic choristoma of the primitive hyaloid system. Surgery (pars plana vitrectomy was successful and the patient returned with visual acuity of 20/20 in both eyes, and with no further complaints.Os autores apresentam relato de um caso de paciente de 44 anos, com história de dificuldade visual no olho esquerdo há 5 anos.

    Twenty-one surgical patients with carcinoma of the rectum (Group 3) were treated with preoperative radiotherapy and intratumoral injections of Pepleomycin and BUdR (5-bromo-2'-deoxyuridine). On the other hand, 25 patients (Group 1) were treated by surgery alone and 7 patients (Group 2) were treated with preoperative radiotherapy alone. The difference in the background factors of the patients for three groups was not significant. The total dose of preoperative radiation was 42.6 Gy., e.i., 30.6 Gy. (1.8 Gy./fr. x 5/wk) delivered to the entire pelvis plus an additional 12 Gy. (3.0 Gy./fr. x 4/wk) to the primary tumor. The reduction rates in tumor regression on roentgenogram for Groups 2 and 3 were 30.5 % and 46.5 %, respectively. The extent of cancer cell invasion in rectal wall of the surgical specimens was examined histopathologically. In the preoperative radiation group, especially in Group 3, it was indicated that the stage of the lesion had been reduced. The rates of patients with an ew of less than 2 mm were 64.0 % in Group 1, 28.6 % in Group 2 and 14.3 % in Group 3 (Group 1 - 3 : p = 0.02). The incidence of positive lymph nodes was higher in Group 1 than in Groups 2 and 3. In a histopathological investigation of the patients in Group 3, the degenerative changes were heavier than in Group 2. Scattered mucocele transformation from the submucosal layer through to the adventitial tissue was noted in Group 3. This study suggests that the clinical and pathological effect of this combination therapy is able to increase the local control and survival rate.

    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.

    With the decline of ovarian hormonal function, from the fifth decade of life, women enter the menopause transition, during which bleeding becomes irregular in duration and time of occurrence. Secondary to ovarian dysfunction, developmental and maturation endometrial anomalies occur, which are clinically translated by abnormal uterine bleeding, which in many cases at this age can be caused by organic lesions (fibroma, polyps, endometritis, endometrial hyperplasia, adenomyosis, etc.). The retrospective study included a total of 256 patients with abnormal uterine bleeding in menopause transition. Statistics showed that the incidence of these types of bleeding increases with age (64.5%) and parity (30.5%), with symptoms consisting mostly in different clinical forms of abnormal uterine bleeding (62.1%), and leiomyomas prevailing at histopathological examination (49.6%). Progesterone replacement therapy was the first therapeutic choice for correcting these types of bleeding. Progesterone therapy is useful not only for therapeutic purposes to amend the bleeding, but also as a precaution against the development of endometrial carcinoma. Progestogens cancel the proliferative and mitogenic effect of estrogens, even when administered in sequential regimen 10-12 days per month.

    characterization. The present study had the aim to describe the histopathological characteristics of subclinical hairy leukoplakia, as well as to carry out a comparative analysis between clinical and subclinical OHL. For that, 11 cases were analyzed - 5 biopsies from patients who presented with the lesion and 6 samples from the borders of tongues obtained in necropsies. The histopathological findings in subclinical OHL were: absence of parakeratosis and papillomatosis, mild acanthosis, ballooning cells and nuclear alterations. In situ hybridization and immunostaining were positive for EBV in the nuclear alterations identified in the histophatological analysis. Based on the identification of EBV in the nuclear alterations, it was possible to conclude that subclinical OHL, similarly to the clinical lesion, presents histopathological features that are specific and sufficient to establish the definitive diagnosis, regardless of the identification of the virus.

    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 Primary malignant lymphomas of the salivary glands are rare, accounting for 2-5% of salivary gland tumors and 5% of extranodal lymphomas, frequently seen in the parotid gland. There are single case reports mentioned in the literature. Clinical presentation is not characteristic and the disease is often overlooked with delay in diagnosis and treatment. We are reporting a case of bilateral parotid gland lymphoma in a 55-year-old male, presented with bilateral enlarged parotids. Magnetic resonance imaging (MRI showed bilateral enlarged parotid glands with multiple well-defined intraparotid lesions. Fine Needle Aspiration Cytology (FNAC of both showed mixed population of lymphoid cells with large monocytoid cells with scant cytoplasm, anisonucleosis with prominent nucleoli, and numerous mitoses suggestive of non-Hodgkin's lymphoma (NHL. Histopathology showed sheets of large lymphoma cells destructing the salivary acini and infiltrating the periparotid fat. Immunohistochemistry (IHC showed diffuse CD20 positivity, B-cell lymphoma 6 protein (Bcl-6 was focally positive and negative for cluster of differentiation (CD 3, CD5, CD10, and Multiple myeloma oncogene-1 (MUM1 which led to the diagnosis of NHL-Diffuse large B cell type.

    Full Text Available BACKGROUND: The nephrotic syndrome is recognized as an independent entity of renal disease for over half a century . 1 Causes of nephrotic syndrome varies with age, time period, geographical location and race. In children, minimal change nephrotic syndrome is the commonest 2 ; however, membranous nephropathy is most frequent in adults . 3 As it commonly affects the younger age group and is associated with high morbidity and mortality, there is a need to understand and diagnose the disease at an early stage. Hence, this study has been done to identify the clinical presentation, biochemical parameters and histopathology associated with nephrotic syndrome in adults and its subtypes. OBJECTIVE: To study the clinical, biochemical and histopathological profile of patients with Adult Nephrotic Syndrome admitted in our tertiary care hospital. METHODS: Prospective study of 100 patients with Adult Nephrotic Syndrome admitt ed in our tertiary care hospital were screened with facial puffiness and pedal edema. They were tested for urine proteinuria, urine protein creatinine ratio or 24 hour urine protein estimation. Later renal biopsy was done for all patients to stratify the subtypes. RESULTS: In this study, males were predominantly affected. Most common presenting complaints were facial puffiness and pedal edema. Systolic BP was increased in 96% of patients and diastolic BP was elevated in 50% of patients. Serum LDL and TGL were elevated in nephrotic syndrome. In young patients less than 40 years Focal Segmental Glomerulosclerosis (FSGS is the commonest type, then Membrano Proliferative Glomerulo Nephritis (MPGN and Minimal Change Disease (MCD. In individuals more than 40 years, membranous nephropathy was predominantly seen followed by FSGS. CONCLUSION: There is a changing trend in primary nephrotic syndrome and FSGS was found to be the commonest subtype. Male preponderance was noticed and also FSGS was found to be more common in younger adults. Most

    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.

    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.

    A severe outbreak of scuticociliatosis occurred in Australian pot-bellied seahorse, Hippocampus abdominalis (Lesson, 1872), kept at the Vancouver Aquarium Marine Science Centre (Vancouver, British Columbia, Canada). Clinical signs included anorexia, lethargy, irregular respiration, and death. Cytology and histopathology revealed a high number of histophagous ciliated protozoa within the tissues. The parasite, identified as Philasterides dicentrarchi, was observed in several internal organs that appeared edematous and hemorrhagic upon postmortem examination. Severe histopathologic lesions were reported in particular in the ovary, the kidney, and the intestine. This infection was successfully treated with metronidazole via bath therapy. No further evidence of this parasite was found in the treated fish.

    Miliary dissemination is a rare form of brain metastasis. The clinical and pathologic features of this form are unclear. We report a 66-year-old man with miliary brain metastases from adenocarcinoma of the lung, describing MRI and neuropathologic findings in the context of previously reported cases. Initial disorientation progressed to an apallic state within 6 months. Although, CT with administration of contrast agent failed to demonstrate any lesions, MRI with Gd-DTPA administration showed multiple enhancing miliary nodules in the cerebral cortex, basal ganglia, thalamus, cerebellum, and brainstem. Some of those nodules also could be seen on T2-weighted imaging without Gd-DTPA, but were difficult to identify conclusively. A histopathologic examination at autopsy disclosed diffusely distributed miliary tumor nodules in a perivascular distribution without surrounding focal edema or reactive gliosis. Notably, this patient with miliary brain metastases developed disorientation followed by unconsciousness, which overshadowed other focal neurologic signs at that time. We should consider this pattern of brain dissemination when a cancer is associated with unexplained disturbance of consciousness. (orig.)

    2013-02-01

    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.

    To measure the strength of agreement in clinical, radiological and histopathological diagnosis of osteosarcoma in a 5 year study period. Addis Ababa University, Black-Lion ('Tikur Anbessa') Hospital-BLH, is the country's highest tertiary level referral and teaching hospital. The departments involved in this study (Radiology, Pathology and Orthopedics) receive referred patients from all over the country. All bone tumor patients, presenting to the three departments at BLH between the study period, December, 2003 - March, 2008 were recruited for the study. 51 patients with radiological diagnosis of osteosarcoma of the extremities were identified and their clinical and histopathological diagnoses reviewed in detail. All patients had a clinical examination, plain radiographs and biopsies of the affected part of the extremity. Radiographs of selected difficult cases were discussed at joint orthopedic & radiologic sessions every week. The radiological and histopathological diagnoses made were categorized separately using WHO classification of bone tumors. Strength of agreement between radiological and histopathological diagnoses was measured using Cohen's Kappa test. Of the total of 216 bone tumor patients presented and biopsied in the five year period, fifty one (51) had osteosarcoma of extremity bones. Commonest age affected by osteosarcoma was 16 (7-55 years) and sex ratio was 1:1. Osteosarcoma was also the single most common clinical, radiological and histological diagnosis made. Considering all bone tumors presented together, the study indicated that radiological diagnosis was confirmed by similar histological diagnosis in 172 out 205 cases (84%) and the corresponding Cohen's Kappa value (0.82) showed excellent level of agreement between radiological and histological diagnoses of all bone tumors. The agreement between radiological and histopathological diagnoses of osteosarcoma of the limbs was 84.5%. There is an excellent agreement between clinical, radiological and

    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.

    Geographic tongue is a chronic, inflammatory, and immune-mediated oral lesion of unknown etiology. It is characterized by serpiginous white areas around the atrophic mucosa, which alternation between activity, remission and reactivation at various locations gave the names benign migratory glossitis and wandering rash of the tongue. Psoriasis is a chronic inflammatory disease with frequent cutaneous involvement and an immunogenetic basis of great importance in clinical practice. The association between geographic tongue and psoriasis has been demonstrated in various studies, based on observation of its fundamental lesions, microscopic similarity between the two conditions and the presence of a common genetic marker, human leukocyte antigen (HLA) HLA-C*06. The difficulty however in accepting the diagnosis of geographic tongue as oral psoriasis is the fact that not all patients with geographic tongue present psoriasis. Some authors believe that the prevalence of geographic tongue would be much greater if psoriatic patients underwent thorough oral examination. This study aimed to develop a literature review performed between 1980 and 2014, in which consultation of theses, dissertations and selected scientific articles were conducted through search in Scielo and Bireme databases, from Medline and Lilacs sources, relating the common characteristics between geographic tongue and psoriasis. We observed that the frequency of oral lesions is relatively common, but to establish a correct diagnosis of oral psoriasis, immunohistochemical and genetic histopathological analyzes are necessary, thus highlighting the importance of oral examination in psoriatic patients and cutaneous examination in patients with geographic tongue.

It is commonly found in individuals whose occupational activities are related to chronic sun exposure and the definitive diagnosis is performed with biopsy. Althoug Exfoliative cytology has been used as a screening procedure to evaluate cancer of the oral cavity no studies have proposed the use of exfoliative cytologic analysis to evaluate and diagnose AC. OBJECTIVE: The purpose of this study was to evaluate lower lip lesions on fishermen related to chronic solar exposure using clinical, cytologic and histopathologic analyses. PATIENTS AND METHODS: Smears taken from the vermilion of the lower lips of 125 fishermen and 30 control individuals were subjected to cytologic analysis. RESULTS: The harvested cells were sufficient for cytologic analysis in 83.2% of the samples. Sixteen fishermen exhibited prominent lower lip lesions that justified biopsy and histological studies. In total, 4 specimens were malignant (3.2%, and 12 displayed epithelial dysplasia, demonstrating that the prevalence of epithelial dysplasia and malignant lesions was high among the fishermen population. These conditions were strongly associated with infiltration and blurring of the vermilion margin of the lower lip. CONCLUSION: The cytologic analysis was not useful for detecting epithelial dysplasia or malignant alterations.

    to present main clinical and hematologic features of pediatric leukemias treated at Hematooncologic department of Pediatric Clinic in Sarajevo during last 7 years. In retrospective study we followed up children with leukemia aged 0-15 who were treated during period of 01.01.1997-31.12.2003. at Hematooncologic department on Pediatric Clinic in Sarajevo. A total number of patient with leukemia was 130 of them 112 (83.2%) had acute lymphoblastic leukemia (ALL), 16 (12.3%) of them had acute myeloid leukemia (AML) and 2 (1.5%) patients had chronic myeloid leukemia (CML). There were 84 (64.6%) boys and 46 (35.4%) girls. Median age of newly diagnosed patients was 6 years and 4 months. Dominant clinical signs were: high temperature-72.9%, fatigue and paleness-74.8% and bone pain-87.9%. Most of the children had leucocitosis (51.5%), anemia (56.1%) and trombocitopenia (57.5%). Most frequent signs at the beginning of the illness are general symptoms like fatigue, unclear febrile state and accented bone pains. Those united signs with complete blood picture finding should be enough reason for suspicion under possible leukemia.

    Trypophobia refers to the fear of, or aversion to, clusters of holes. We assessed clinical features of trypophobia and investigated whether it most resembled a specific phobia or obsessive-compulsive disorder. An online survey was conducted to gather information on sociodemographic variables, course and duration, severity, associated features, comorbid psychiatric diagnoses, and levels of psychological distress and impairment in individuals with trypophobia. The survey also explored whether such individuals experienced more fear or disgust, and whether symptoms showed more resemblance to a specific phobia or to obsessive-compulsive disorder. Associations of symptom severity and duration with degree of impairment were investigated. One hundred and ninety-five individuals completed the questionnaire. Symptoms were chronic and persistent. The most common associated comorbidities were major depressive disorder and generalized anxiety disorder. Trypophobia was associated with significant psychological distress and impairment. The majority of individuals experienced disgust rather than fear when confronted with clusters of holes, but were more likely to meet DSM-5 criteria for specific phobia than for obsessive-compulsive disorder. Symptom severity and duration were associated with functional impairment. Given that individuals with trypophobia suffer clinically significant morbidity and comorbidity, this condition deserves further attention from clinicians and researchers.

    Background/Aims Chronic urticaria (CU) is defined as itchy wheals lasting 6 weeks or more. As the aged population increases worldwide, it is essential to identify the specific features of this disease in the elderly population. Methods We investigated the prevalence and clinical features of CU in elderly patients. Medical records of 837 CU patients from the outpatient Allergy Clinic of Ajou University Hospital, Korea were analyzed retrospectively. Patients with chronic spontaneous urticaria according to the EAACI/GA2LEN/EDF/WAO guidelines were included. Patients older than 60 years were defined as elderly. Results Of the 837 patients, 37 (4.5%) were elderly. In elderly versus nonelderly CU patients, the prevalence of atopic dermatitis (AD) was significantly higher (37.8% vs. 21.7%, respectively; p = 0.022), while that of aspirin intolerance was lower (18.9% vs. 43.6%, respectively; p = 0.003) in terms of comorbid conditions. The prevalences of serum specific immunoglobulin E antibodies to staphylococcal enterotoxin A and staphylococcal enterotoxin B were considerably higher in elderly CU patients with AD than in those without AD (37.5% vs. 0%, respectively). Conclusions Elderly patients with CU had a higher prevalence of AD. Therefore, there is a need to recognize the existence of AD in elderly CU patients. PMID:25378979

    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.

    Meningiomas constitute 25% of primary spinal tumors and predominantly involve the thoracic spinal cord. Although calcifications are commonly seen in intracranial meningiomas, gross calcifications are observed in only 1-5% of all spinal meningiomas. We report the clinical findings, surgical strategy and histological features of 9 patients with ossified spinal meningiomas (OSMs). Clinical and surgical features of 9 patients with ossified spinal meningiomas were retrospectively reviewed. There were 8 women and 1 man with a mean age of 59 years. In 7 patients, the lesions were localized in the thoracic segment of the spine while in 2 patients in the lower cervical segment. All patients presented with weakness of the lower limbs and hypoesthesia below the site level of the lesion. Only 2 patients presented with urinary incontinence. Gross-total resection of the tumor was achieved in 6 patients while in 3 a subtotal removal of the meningioma was obtained. In all patients the postoperative course was uneventful. Six patients presented with a significant neurological improvement while in 3 patients a mild improvement was observed. Microscopically, all tumors showed typical histological pattern of ossified meningioma. OSMs are amenable to surgery if the complete removal can be achieved. Because of their hard-rock consistency complete resection can be challenging. In difficult cases, subtotal removal can be advised and follow-up imaging is mandatory. Overall, the risk of long-term recurrence of the lesions is low, and a good clinical outcome after total or subtotal removal can be expected. Copyright © 2016 Elsevier B.V. All rights reserved.

    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

    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.

    In psychomotor retardation there is an abnormal development of mental, sensory and motor skills associated with ocular manifestations. There are biological and psychosocial risk factors that predispose an individual to neurological damage. From 50% to 80% of patients with strabismus retardation have special features that differentiate it from the rest of strabismus in healthy patients. To determine the most common type of strabismus in patients with psychomotor retardation and their clinical features. Patients with psychomotor retardation and strabismus were included. An ophthalmological examination was performed, as well as an evaluation of the characteristics of strabismus, including perinatal and post-natal history. Esotropia was the most frequent squint with 65.3%, followed by exotropia with 32.7%. The variability in the squint magnitude was 60% in both types, and 6 patients had dissociated vertical deviation. Most of the patients started to present strabismus since they were born. The most frequent perinatal risk factors were threatened miscarriage, pre-eclampsia, foetal distress, and hypoxia. Esotropia is the most common type of strabismus in psychomotor retardation. The variability of squint magnitude is a characteristic in these patients. The moderate variability is the most frequent in both esotropia and exotropia. The most common refractive error is hyperopic astigmatism in esotropia and the myopic kind in exotropia.

    Full Text Available Abstract Background Clinical mastitis is an important disease in sheep. The objective of this work was to identify causal bacteria and study certain epidemiological and clinical features of clinical mastitis in ewes kept for meat and wool production. Methods The study included 509 ewes with clinical mastitis from 353 flocks located in 14 of the 19 counties in Norway. Clinical examination and collection of udder secretions were carried out by veterinarians. Pulsed-field gel electrophoresis (PFGE was performed on 92 Staphylococcus aureus isolates from 64 ewes. Results and conclusion S. aureus was recovered from 65.3% of 547 clinically affected mammary glands, coagulase-negative staphylococci from 2.9%, enterobacteria, mainly Escherichia coli, from 7.3%, Streptococcus spp. from 4.6%, Mannheimia haemolytica from 1.8% and various other bacteria from 4.9%, while no bacteria were cultured from 13.2% of the samples. Forty percent of the ewes with unilateral clinical S. aureus mastitis also had a subclinical S. aureus infection in the other mammary gland. Twenty-four of 28 (86% pairs of S. aureus isolates obtained from clinically and subclinically affected mammary glands of the same ewe were indistinguishable by PFGE. The number of identical pairs was significantly greater than expected, based on the distribution of different S. aureus types within the flocks. One-third of the cases occurred during the first week after lambing, while a second peak was observed in the third week of lactation. Gangrene was present in 8.8% of the clinically affected glands; S. aureus was recovered from 72.9%, Clostridium perfringens from 6.3% and E. coli from 6.3% of the secretions from such glands. This study shows that S. aureus predominates as a cause of clinical ovine mastitis in Norway, also in very severe cases. Results also indicate that S. aureus is frequently spread between udder halves of infected ewes.

Methods Conservative therapy, puncture and drainage, hematoma removal and/or decompressive craniectomy were used in the treatment of 630 intracerebral hemorrhage (ICH patients, who were divided into 2 groups: 30 cases with MICH and another 600 cases with solitary intracerebral hemorrhage (SICH. Three months after onset, modified Rankin Scale (mRS was used to evaluate the prognosis of all cases. Results Compared with patients in SICH group, the occurrence rate of hypertension > 5 years (P = 0.008, diabetes mellitus (P = 0.024, hypercholesterolemia (P = 0.050 and previous ischemic stroke (P = 0.026 were all significantly higher in MICH group. The mean arterial pressure (MAP level (P = 0.002 and the incidence of limb movement disorder (P = 0.000 were significantly higher in patients with MICH than those with SICH. Basal ganglia and thalamus were the predilection sites of hematoma (P = 0.001. Patients with MICH had worse prognosis compared to those with SICH 3 months after onset (P = 0.006. Conclusions Hypertension > 5 years, diabetes mellitus, hypercholesterolemia and ischemic stroke were identified to be the pathophysiological basis of MICH in this study. All patients with MICH had more serious clinical manifestations after onset and worse prognosis. DOI: 10.3969/j.issn.1672-6731.2016.01.008

    To report radiologic findings with histopathologic correlations of humidifier disinfectant-associated children's interstitial lung disease (HD-chILD) and to compare computed tomography (CT) findings between survivors and non-survivors. Forty-seven children with HD-chILD (27.4 ± 12.4 months old) were categorized as survivors (n = 25) and non-survivors (n = 22). The patterns, distributions, and chronological changes in lung lesions at follow-up CT were investigated. Histopathologic correlations were performed in 23 patients. CT features were characterized by chronological changes, from consolidation to centrilobular opacities, and lesions eventually became faint centrilobular nodules. Histopathologic features were bronchocentric-distributed fibro-inflammatory lesions, which were more profound in the advanced stage than the early stage. Consolidation ≥30 % [hazard ratio (HR), 2.932], centrilobular opacities ≥60 % of the total lung volume (TLV; HR, 0.206) and spontaneous air leaks (HR, 3.457) were significant factors associated with patient survival, as per univariate analysis. Consolidation ≥30 % (HR, 3.519), centrilobular opacities ≥60 % (HR, 0.205) and diffuse ground glass opacity (GGO) ≥70 % of the TLV (HR, 3.521) were significant factors associated with patient survival, as determined via multivariate analysis. Distinctive chronological CT features were observed in the HD-chILD images. Spontaneous air leaks, consolidation, GGO, and centrilobular opacities were prognostic factors. (orig.)

    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.

    Spindle epithelial tumor with thymus-like differentiation (SETTLE) of the thyroid gland is a very rare tumor. It is believed to originate from ectopic thymus tissue within the thyroid gland or from branchial pouch remnants that differentiate along the thymic line. A few reports of SETTLE have been presented, but to the best of our knowledge, there is no case report in which detailed preoperative imaging features of SETTLE have been described. In addition, there are no case reports of SETTLE in Korean patients. Thus, we report a case of SETTLE with detailed preoperative ultrasonography and computed tomography features, cytological findings and histopathological results.

    2016-09-01

    Full Text Available Background: Psoriasiform dermatitis is a frequently encountered terminology in a wide variety of inflammatory dermatoses. It often poses challenges to both dermatologists and pathologists alike. Clinical features when considered alone may not be reliable, as they vary with both disease duration and treatment. On the contrary, histopathological material constitutes definite hard evidence, which can be preserved and will continue to be available for future review. The objective of the study is to study the histopathological findings in Psoriasiform dermatitis.Materials and Methods: This is a retrospective study in a tertiary care centre in Kerala, South India. All cases diagnosed as Psoriasis or mentioned as one of the differential diagnosis were included. The material included 66 skin biopsies. Patients with a previous diagnosis of the same were excluded from the study.Results: The lesions comprised 9% of the total number of skin biopsies. The age distribution pattern revealed that the highest percentage was in the 41-60 year age group (50% with a male preponderance of 65%. Psoriasis was the most common lesion (60.60% and Lichen simplex chronicus was the second most common lesion (10.60 %, encountered in the study.Conclusion: Some of the histopathological features are specific and characteristic for each entity like Psoriasis, Pityriasis rubra pilaris, Pityriasis rosea and Inflammatory linear verrucous epidermal nevus whereas some overlap in lesions like Prurigo nodularis, Lichen simplex chronicus and Allergic contact dermatitis. Hence, combination of proper clinical observation and histopathological study will give a conclusive 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.

    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.

    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.

    The β-tropomyosin gene encodes a component of the sarcomeric thin filament. Rod-shaped dimers of tropomyosin regulate actin-myosin interactions and β-tropomyosin mutations have been associated with nemaline myopathy, cap myopathy, Escobar syndrome and distal arthrogryposis types 1A and 2B. In this study, we expand the allelic spectrum of β-tropomyosin-related myopathies through the identification of a novel β-tropomyosin mutation in two clinical contexts not previously associated with β-tropomyosin. The first clinical phenotype is core-rod myopathy, with a β-tropomyosin mutation uncovered by whole exome sequencing in a family with autosomal dominant distal myopathy and muscle biopsy features of both minicores and nemaline rods. The second phenotype, observed in four unrelated families, is autosomal dominant trismus-pseudocamptodactyly syndrome (distal arthrogryposis type 7; previously associated exclusively with myosin heavy chain 8 mutations). In all four families, the mutation identified was a novel 3-bp in-frame deletion (c.20_22del) that results in deletion of a conserved lysine at the seventh amino acid position (p.K7del). This is the first mutation identified in the extreme N-terminus of β-tropomyosin. To understand the potential pathogenic mechanism(s) underlying this mutation, we performed both computational analysis and in vivo modelling. Our theoretical model predicts that the mutation disrupts the N-terminus of the α-helices of dimeric β-tropomyosin, a change predicted to alter protein–protein binding between β-tropomyosin and other molecules and to disturb head-to-tail polymerization of β-tropomyosin dimers. To create an in vivo model, we expressed wild-type or p.K7del β-tropomyosin in the developing zebrafish. p.K7del β-tropomyosin fails to localize properly within the thin filament compartment and its expression alters sarcomere length, suggesting that the mutation interferes with head-to-tail β-tropomyosin polymerization and with

    Purpose The aim of this study was to investigate how clinical features such as sex, age, etiologic factors, and presenting symptoms of odontogenic sinusitis are differentiated from other types of sinusitis. Also, this study was designed to find methods for reducing the incidence of odontogenic sinusitis. Materials and Methods A retrospective chart analysis was completed on twenty-seven patients with odontogenic sinusitis. They were all treated at Kangbuk Samsung Hospital between February 2006 and August 2008. The study protocol and informed consent forms were approved by the institutional review boards for human beings at Kangbuk Samsung Hospital. Results Ten patients (37.0%) had dental implant related complications and 8 (29.6%) had dental extraction related complications. Unilateral purulent nasal discharge was the most common symptom (66.7%). The therapeutic modality included transnasal endoscopic sinus surgery in 19 (70.4%) patients, and a Caldwell-Luc operation in two (7.4%) patients. Conclusion In our study, there was no significant difference in the incidence between genders. The average age of the patients was 42.9 years. The incidence was highest in the fourth decade. There were no significant differences between the symptoms of odontogenic sinusitis and that of other types of sinusitis. However, almost all of the patients with odontogenic sinusitis had unilateral symptoms. Iatrogenic causes, which include dental implants and dental extractions, were the most common etiologic factors related to the development of odontogenic sinusitis. Therefore, a preoperative consultation between a rhinologist and a dentist prior to the dental procedure should be able to reduce the incidence of odontogenic sinusitis. PMID:20879062

    Full Text Available ObjectiveTo analyze the clinical data of Klebsiella pneumoniae liver abscess (KPLA, and to provide a reference for early diagnosis and proper treatment. MethodsThe etiological features of 156 patients with bacterial liver abscess (BLA and positive culture results who were hospitalized in The First Hospital Affiliated to Nanjing Medical University from March 2009 to July 2015 were analyzed retrospectively. According to the culture results, BLA patients were divided into KPLA group (81 patients and non-KPLA (NKPLA group (61 patients, and other positive strains including Escherichia coli were found in the other 14 patients with positive culture results for Klebsiella pneumoniae. The clinical, laboratory, and imaging data of KPLA and NKPLA were compared. The t-test was applied for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was applied for continuous data with skewed distribution between groups; the chi-square test or Fisher′s exact test was applied for comparison of categorical data between groups. ResultsThe most common pathogenic bacteria for BLA were Klebsiella pneumonia. In comparison with the NKPLA group, the KPLA group had a significantly higher proportion of male patients (χ2=4.50, P=0.03, a significantly higher proportion of patients with diabetes (χ2=27.28,P<0.001, and a significantly lower proportion of patients who complained of abdominal pain (χ2=5.24, P=0.02. In the aspects of underlying diseases, the prevalence of biliary tract diseases, previous abdominal surgery, and a history of intraperitoneal tumors showed significant differences between the NKPLA group and the KPLA group (χ2=18.38, 20.87, and 21.68, all P<0.001. As for laboratory examination, the NKPLA group had a significantly greater reduction in hemoglobin compared with the KPLA group (t=4.903, P<0.001. In terms of imaging examination, most BLA patients showed a single lesion in the right lobe of the liver, but

    To evaluate whether standardized uptake value (SUV) and/or metabolic rate of glucose (MRglu) are different among epithelioid, mixed, and spindle cell uveal melanomas, as well as between low and high risk melanomas; to correlate ultrasonographic data and metabolic parameters with histopathological features; and to assess the role of {sup 18}F-FDG PET/CT for evaluating prognosis. Of 34 eligible patients prospectively enrolled with clinical suspicion of medium/large uveal melanoma, 26 (15 men, mean age 62.8 {+-} 11.8 years) were evaluated. All patients underwent metastatic work-up, 3-D dynamic brain and whole-body {sup 18}F-FDG PET/CT, and surgery. Of the 26 ocular lesions, 23 showed {sup 18}F-FDG uptake, with a sensitivity of 88 %. MRglu was significantly higher in the epithelioid cell melanomas than in the spindle cell melanomas, as well as in high-risk lesions than in low-risk lesions (p = 0.01, p = 0.02, respectively). SUV and MRglu were correlated with histopathological features while ultrasonographic data were not. MRglu is useful for distinguishing the different cell types in uveal melanoma, as well as high-risk from low-risk lesions, while SUV is not. MRglu provides a more accurate evaluation of glucose consumption, whereas SUV provides only an estimation. In addition, the metabolic parameters correlate with histopathological features, well also reflecting cellular behaviour in ocular malignancy. A longer follow-up is needed to assess the role of {sup 18}F-FDG in evaluating prognosis. (orig.)

    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

    Full Text Available Objective: Recent studies have shown that tumor cell adhesion molecules CD44 and matrix metalloproteinases (MMP-2 are expressed strongly in many tumors and associated closely with invasion and metastasis of these tumors. Although solitary fibrous tumors (SFT have a good prognosis, a minority behave malignantly. The aim of this study was to analyze the correlation between CD44 and MMP-2 expression with histopathological parameters in SFT.Material and Method: Haemotaxylin-Eosin stained sections of 10 patients with SFT were reexamined for evaluation of histopathological parameters. Immunostaining of CD44 and MMP-2 was performed by using the streptavidin-biotin method with mouse monoclonal antibody.Results: Our cases consisted of three male and seven female patients with a mean age of 54.5 years. Three patients had a history of asbest exposure. Complete resection was performed in 2 malignant (multiple masses and 8 benign SFT cases. One intrapulmonary tumor was treated with pneumonectomy. 3 cases originated from the right and 7 from the left hemithorax. Tumor size ranged from 5 to 27cm. All cases expressed strong CD44. Only 2 malignant SFT and intrapulmonary SFT expressed focal MMP-2.Conclusion: Although MMP-2 positivity was observed in 2 malignant cases, CD44 positivity was not associated with malignancy criteria in solitary fibrous tumors.

    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.

    A 9 year old male mixed-breed dog was presented for progressive aggressiveness towards the owner. The neurological evaluation was consistent with a forebrain syndrome. Magnetic Resonance Imaging (MRI) of the brain revealed enlargement of the third ventricle and presence of a large spheroidal neoplasm in the sellar/parasellar region suggestive of a pituitary macroadenoma. On the owner request, the dog was euthanized. Histopathological examination revealed the presence of a pituitary chromophobe carcinoma. To the author’s knowledge, pituitary carcinomas have been rarely described in dogs, especially the chromophobe subtype. PMID:27800300

    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.

    2007-07-01

    Full Text Available Abstract Background We present an analysis of the utility of multispectral versus standard RGB imagery for routine H&E stained histopathology images, in particular for pixel-level classification of nuclei. Our multispectral imagery has 29 spectral bands, spaced 10 nm within the visual range of 420–700 nm. It has been hypothesized that the additional spectral bands contain further information useful for classification as compared to the 3 standard bands of RGB imagery. We present analyses of our data designed to test this hypothesis. Results For classification using all available image bands, we find the best performance (equal tradeoff between detection rate and false alarm rate is obtained from either the multispectral or our "ccd" RGB imagery, with an overall increase in performance of 0.79% compared to the next best performing image type. For classification using single image bands, the single best multispectral band (in the red portion of the spectrum gave a performance increase of 0.57%, compared to performance of the single best RGB band (red. Additionally, red bands had the highest coefficients/preference in our classifiers. Principal components analysis of the multispectral imagery indicates only two significant image bands, which is not surprising given the presence of two stains. Conclusion Our results indicate that multispectral imagery for routine H&E stained histopathology provides minimal additional spectral information for a pixel-level nuclear classification task than would standard RGB imagery.

    The aim of this study was to evaluate the staging accuracy of magnetic resonance imaging (MRI) with an endorectal surface coil on patients with endometrial cancer compared to results obtained using the International Federation of Gynecology and Obstetrics (FIGO) classification and histopathology. In this prospective study, patients with biopsy-proven endometrial cancer were staged clinically using the FIGO classification before undergoing 1.5 T MRI with an endorectal surface coil (eMRI). The staging results from the FIGO classification and from eMRI were compared with the histopathological results after surgery. Furthermore, each patient was given a questionnaire designed by the authors to evaluate the patients' opinions on eMRI. The responses were examined using the methods of descriptive analysis. A total of 33 consecutive patients were recruited and clinically staged before undergoing eMRI. Subsequently, 21 patients underwent primary surgery and 12 patients primary radiochemotherapy. The FIGO stages were identical to the histopathological results in 17 (81 %) cases, and those of eMRI were identical in 15 (71 %). In 13 (62 %) cases, FIGO and eMRI staged identically. In 12 (57 %) of the 21 cases, all three staging modalities diagnosed the same tumor stage. eMRI overstaged the tumor in four patients and understaged it in two. All T1a tumors were staged correctly by eMRI. Eighteen patients answered the questionnaire, of whom 11 (61 %) patients stated that their experience with eMRI was overall positive. It seems feasible in principle to employ eMRI for diagnosing patients with endometrial cancer stage T1a. Yet, the results of eMRI for our study population were not better than the results obtained using the FIGO classification or than those from using MRI without an endorectal surface coil. eMRI thus does not meet the expectations based on its use in other pelvic tumor entities.

    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

The studies of histopathology on diseases in EGs, however, are scarce. In the present study, we systematically investigated EGs in 36 resection cases of gastric cardiac carcinomas involving the esophagus (GCE in Chinese patients. All cases showed chronic inflammation in EGs and 14 (39% with Helicobacter pylori infection. Hyperplasia, atrophy, and dysplasia were common in EGs and observed in 21 (58%, 14 (39%, and 28 (78% cases, respectively. These changes were associated with various types of metaplasia, including intestinal (6, 17%, oncocytic (26, 72%, pancreatic acinar (11, 30%, and squamoid metaplasia (8, 22%. Oncocytic metaplasia was patchy, frequently replaced the entire lobule with dysplastic features. Pancreatic acinar metaplasia was present in superficial EGs as small acinar patches. Squamoid metaplasia was limited to the EG drainage ductile epithelium without keratin pearls or intercellular bridges; however, cytoplasmic vesicles and secretory vacuoles were common, suggesting dual differentiation.

    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.

    Full Text Available Background and objectives: This study was conducted to compare the diagnostic accuracy of fine needle aspiration cytology in differentiating the benign and malignant lesions of palpable breast lump with histopathological correlation and also to study the accuracy of the needle tip localizing the tumor during fine needle aspiration cytology procedure. Methods: Two years prospective study was conducted in our institution and in that 100 patients underwent fine needle aspiration cytology of the palpable breast lump after thorough physical examination. The cytological diagnosis was classified in to 3 groups benign, suspicious and malignant. After this reporting all the patients were later subjected to open/excision biopsy and its histopathological confirmation. Later diagnostic accuracy of cytology reporting was compared with that of histopathology. Accuracy of the needle tip in localizing the tumor in fine needle aspiration cytology was also studied by comparing the normal glandular cell aspirate with tumor cell aspirate. Repeat cytology was carried out before open/excision biopsy if the pathologist reports the cytology slide as “inadequate”. Results: We had accuracy rate of 100% for benign lesion and 93.10% for malignant lesion with false negative rate of 6.9% and false positive rate of zero with fine needle aspiration cytology in the diagnosis of palpable breast lump. The overall sensitivity of fine needle aspiration in diagnosing the palpable breast lump is 93.10%, specificity is 100%, positive predictive value is 100% and negative predictive value is 90.47%. Since inadequate sampling rate is 2% in our study, the accuracy rate of needle tip in localizing the tumor in fine needle aspiration cytology is 98%. Conclusion: Since our diagnostic accuracy rate and predictive values are very high and comparable to any other published series it can be advised that the patients in which fine needle aspiration cytology is unequivocally diagnostic for

    Zidovudine-induced myopathy is characterized by reversible muscle weakness, wasting, myalgia, fatigue, and elevated creatine kinase (CK). Some zidovudine-treated patients with normal muscle strength experience excessive fatigue, myalgia, or transient mild CK elevations that improve when zidovudine is stopped. To determine the cause of these symptoms, we studied 13 physically fit, HIV-infected men who developed fatigue, myalgia, and reduced endurance, while taking zidovudine for a mean period of 20 months (2-39 months), with neurological evaluation and muscle biopsy processed for enzyme histochemistry and electron microscopy (EM). All subjects had normal muscle strength. In 6 of the 13 patients, muscle biopsies were normal by enzyme histochemistry. EM, however, demonstrated proliferation of normal or abnormal mitochondria, and increased amounts of lipid, glycogen, and lipofuscin. Electromyographic (EMG) studies (5/5) and serum CK (6/6) were normal. The other 7 individuals had signs of moderate to severe mitochondrial abnormalities shown by both light microscopy and EM, characterized by severe destruction, vacuolization, and rare paracrystalline inclusions. Most had elevated CK (4 out of 7) and normal EMG (5 out of 7). The severity of morphological abnormalities did not correlate with duration of HIV infection, zidovudine therapy, or zidovudine dosage. We conclude that in zidovudine-treated patients, symptoms of fatigue, myalgia, reduced endurance, and exercise intolerance represent early signs of zidovudine-induced mitochondriotoxicity, which causes an energy shortage within the muscle fibers even when muscle strength is still normal. Zidovudine, a DNA chain terminator, results in overt myopathy when a critical threshold of molecular, histological, and biochemical dysfunction of mitochondria is crossed, which seems to vary between individuals.

    Vasculitis of the breast (VB) may be an isolated finding or a manifestation of systemic vasculitis. In the current study we sought to characterize isolated VB (IVB) and compare it to VB in the setting of systemic vasculitis. We studied VB cases in the literature and patients cared for at our institution. We analyzed clinical, laboratory, and histologic features (including vessel size and type of inflammatory infiltrates); course of illness; biopsy procedure; and treatment. Based on the presence of localized or systemic disease at the time of disease presentation and during the follow-up, we divided patients into 3 groups: IVB (Group 1), VB with proven or indirect evidence of systemic vasculitis (Group 2), and VB with possible systemic involvement (Group 3). We identified a total of 34 cases of VB (30 from PubMed [National Library of Medicine, Bethesda, MD] and 4 from our pathology database). All patients presented with breast lesions, which were the only expression of disease in 16 (47%). Eighteen, 6, and 10 patients belonged to Group 1, 2, and 3, respectively. Constitutional symptoms were present less often in Group 1. Musculoskeletal symptoms occurred only in Groups 2 and 3. Patients in Groups 2 and 3 had higher erythrocyte sedimentation rates and lower hemoglobin levels, and also received corticosteroids more frequently than those in Group 1. No differences were found in the other analyzed parameters between groups. In summary, VB is uncommon, and in about half of the cases, occurs in the form of IVB. Histologic characteristics do not correlate with disease extent. In IVB patients, constitutional and musculoskeletal manifestations are usually absent. Such patients generally do not require systemic therapy and may be cured by resection alone.

    SEE THAL AND VANDENBERGHE DOI101093/BRAIN/AWW057 FOR A SCIENTIFIC COMMENTARY ON THIS ARTICLE: Post-mortem Braak staging of neurofibrillary tau tangle topographical distribution is one of the core neuropathological criteria for the diagnosis of Alzheimer's disease. The recent development of positron emission tomography tracers targeting neurofibrillary tangles has enabled the distribution of tau pathology to be imaged in living subjects. Methods for extraction of classic Braak staging from in vivo imaging of neurofibrillary tau tangles have not yet been explored. Standardized uptake value ratio images were calculated from 80-100 minute (18)F-AV-1451 (also known as T807) positron emission tomography scans obtained from n = 14 young reference subjects (age 21-39 years, Mini-Mental State Examination 29-30) and n = 173 older test subjects (age 50-95 years) comprising amyloid negative cognitively normal (n = 42), clinically-diagnosed mild cognitive impairment (amyloid positive, n = 47, and amyloid negative, n = 40) and Alzheimer's disease (amyloid positive, n = 28, and amyloid negative, n = 16). We defined seven regions of interest in anterior temporal lobe and occipital lobe sections corresponding closely to those used as decision points in Braak staging. An algorithm based on the Braak histological staging procedure was applied to estimate Braak stages directly from the region of interest profiles in each subject. Quantitative region-based analysis of (18)F-AV-1451 images yielded region of interest and voxel level profiles that mirrored key features of neuropathological tau progression including profiles consistent with Braak stages 0 through VI. A simple set of decision rules enabled plausible Braak stages corresponding to stereotypical progression patterns to be objectively estimated in 149 (86%) of test subjects. An additional 12 (7%) subjects presented with predefined variant profiles (relative sparing of the hippocampus and/or occipital lobe). The estimated Braak

    Full Text Available Innate immunity consists of macrophages, neutrophils, natural killer cells, mucosal immunuglobulins and the comlement system. Mannose binding lectin (MBL takes part in innate immunity through opsonisation and complement activation. MBL deficiency is associated with some infections and autoimmune disorders. However some studies indicate that MBL deficiency alone is not essential for immunity but it may intensify the clinic picture of an immune deficiency that already exists. This article refers to clincal studies related to MBL and brings up the clinical importance of MBL deficiency. [Archives Medical Review Journal 2013; 22(4.000: 565-574

    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.

    The infundibular keratinizing acanthoma (IKA) is a rare epithelial benign keratin-containing neoplasm of hair follicles. The purpose of this study was to evaluate the defining histopathologic architecture of IKA. A typical IKA consisted of a keratin-filled crypt in the dermis and subcutis that opened to the skin surface. Most of this tumor occurred on the back, neck, head, and the shoulders. Microscopically, the dermal nodules were focally contiguous in both the dermis and subcutis. Furthermore, most histological lesions are consistent with a simple or multiloculated cyst filled with keratin and lined by a wall of stratified squamous epithelium; keratin appears as a concentric lamellar mass, with a keratotic pearly aspect. Histological examination of the cutaneous lesions revealed that the growths were comprised of IKA. IKA of man and dog were compared, and it was concluded that although they are similar in many respects, they are not identical entities. To the best of our knowledge, this is the first report on the prevalence of IKAs among the population of owned dogs in Iran.

    Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is characterized by panniculitic infiltrates that may be difficult to distinguish from inflammatory disorders, particularly lupus erythematosus profundus (LEP). We report on 11 patients (M:F=5:6; median age: 49 y; range: 20 to 75 y) presenting with lobular panniculitic infiltrates showing histopathologic features of both SPTCL and LEP in different parts of the same biopsy specimen. The areas showing aspects of SPTCL revealed dense infiltrates of small and medium-sized, atypical α/β T-cytotoxic lymphocytes with focal rimming of the adipocytes and high proliferation. In other areas the infiltrate was composed of nodules of B lymphocytes arranged characteristically at the periphery of the fat lobules and in the septa and showing a low proliferation rate. CD123-positive plasmocytoid dendritic cells arranged in small clusters could be observed in 3 cases. Our observation raises an important question concerning the relationship between SPTCL and LEP. A simple chance overlap of 2 unrelated pathologies seems unlikely, as we could observe these unusual features in 11 cases, much more than mere chance would justify. Three other hypotheses may explain the features observed in our patients: (1) these are examples of SPTCL with focal histologic features mimicking those of LEP; (2) these are examples of LEP with focal atypical histologic features mimicking those of SPTCL; (3) SPTCL and LEP may represent 2 ends of a spectrum, a hypothesis that may be supported by the frequent association of the 2 diseases.

    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.

    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.

    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.

    Full Text Available Dubin-Johnson syndrome (DJS is a rare autosomal recessive disease caused by deficiency of the canalicular multi-specific organic anionic transporter (CMOAT protein. The consequent impairment of conjugated bilirubin secretion into the bile results in hyperbilirubinemia, and the manifestation is black pigment depositing in liver cells under microscope and black liver from macroscopy. However, DJS appears to be a benign disease and no specific treatment has been developed. Misdiagnosis of DJS is common and patients frequently experience repeated visits to physicians during which they undergo a battery of unnecessary clinical testing. This situation may be further complicated by concomitant diseases, which are only recently being recognized and may be the primary etiology or a promoting factor for the patient’s prolonged jaundice. Moreover, the patients who tend to present to clinic during middle and old age which is the rare morbidity age can be easily misdiagnosed. As the disease can be easily ignored. In this review, we summarize the known information regarding DJS pathogenesis, clinical characteristics, and diagnostic methods in order to improve physicians’ awareness of the disease.

    Full Text Available Aim: The aim of the study was to determine the clinical and histopathological effect on palatal hyperplasia caused by suction cups by different methods of management used for recovery of abused tissues. Materials and Methods: A total of 35 subjects agreed for biopsy procedure, from 50 patients who gave consent for the study. Out of the 35 subjects, 20 were randomly selected for treatment with discontinuation of denture (Group I and 15 selected for denture relined with tissue conditioner (COE-comfort (Group II. Punch biopsy procedure was performed on these patients to study the histopathology of the lesion before the two modalities of treatment was administered on them. Results: Inflammation caused by suction cup decreased considerably by both the treatment modalities, i.e., the use of tissue conditioner as well as discontinuation of denture (tissue rest for a period of 2 weeks. Conclusion: It was concluded that wearing denture day and night considerably increased the severity of inflammatory papillary hyperplasia of palate. Healing was better with tissue conditioner when compared with tissue rest.

    A. Rocha

    2012-01-01

    Full Text Available A 6-year-old Lusitano stallion was referred to our centre due to an enlarged left testicle. Anamnesis indicated that the stallion had a chronic hypertrophy of the left testicle, with no apparent ill effect on work (dressage training or semen production. Prolonged use of anti-inflammatory drugs (NSAIDs and antibiotics were probable. Upon examination of the animal, it was found that clinical signs were compatible with chronic testicular degeneration or fibrosis. Ultrasound scanning did not evidence the exuberant macroscopic lesions seen upon hemicastration of the left testicle, but it showed in the left spermatic cord a conspicuous absence of the typical hypoechogenic areas representing the pampiniform plexus. Swabbing of the penis, prepuce, and distal urethra resulted in the isolation of Rhodococcus equi and Corynebacterium spp. However, histopathological examination did not support infectious orchitis as cause of the lesions and no bacterial growth was obtained from swabbing of the parenchyma in the excised testicle. Histopathological findings were compatible with chronic orchitis with fibrosis and necrosis, probably secondary to ischemia of the testicular parenchyma. After hemi-castration, the stallion resumed semen production at acceptable levels.

    Full Text Available 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.

    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.

    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.

    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.

    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 Background: Leprosy has been a major public-health problem in many developing countries for centuries. According to the National Leprosy Elimination Programme report of March 2012, there were a total of about 0.13 million cases of leprosy in India, 9.7% of which were children. Numerous studies have investigated child leprosy amongst reported cases however, studies pertaining to proportion and characteristics of undetected childhood cases in the community are very few. Aim: To examine the clinical, bacteriological, and histopathological characteristics of newly detected child leprosy cases in the community. Methods: The population survey conducted from June to September 2007 and the defined rural areas, which included five primary health centers of Panvel Taluka, in Raigad district and urban areas, which included M-east ward of the municipal corporation of greater Mumbai of western Maharashtra, India. Results: House-to-house survey yielded 32 and 37 so far, undetected child cases of leprosy in the rural and urban region, and the prevalence rate was 10.5 and 1.5 per 10,000, respectively. The age of child leprosy cases detected, ranged from 3 to 14 years with a mean of 10.06 ± 3.35 years in the rural and 9.97 ± 3.12 years in the urban area. Most of the cases were paucibacillary (62%. A large proportion of children (49% had single skin lesion (SSL. Of the 19 SSL cases examined histopathologically, 15 (99% showed features of borderline tuberculoid, 1 (5% borderline lepromatous and 3 (16% had indeterminate type of leprosy. Tuberculoid leprosy was not seen in any, indicating less likelihood of self-healing. Overall, three cases had deformity (grade 1 = 1 and grade 2 = 2 and 31% of multibacillary cases were smear positive. Conclusion: The clinical, bacteriological, and histopathological characteristics of newly detected child cases in the community evidently indicate the grave nature of the problem of undetected child leprosy, recent active

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 Dirofilarioses are zoonoses caused by filaria of the genus Dirofilaria, the parasites of domestic and wild animals. People are just random carriers of this parasite. In Europe, human dirofilariosis is caused by two species: Dirofilaria repens ( D. repens, also known as a species of The Old World , usually with the superficial localization of infection, and D. immitis, which is present throughout the world, and causes, beside superficial, visceral dirofilariosis. So far, based on the data from reference literature, it can be observed that in Serbia about 34 cases of human dirofilariosis have been diagnosed and published. It is assumed that the prevalence of this parasitosis is significantly higher as our country is an endemic area for dirofilariosis in dogs and the region where species of mosquitoes, which are transitory hosts and vectors of Dirofilaria spp., are present. The clinical picture of dirofilariosis depends on the type and location of the parasite in the human body. In our country, patients diagnosed with dirofilariosis had subcutaneous or subconjunctival infection in the majority of cases. Ocular dirofilariosis may affect the orbit and the periorbital region, the skin of the eyelids, the conjunctiva, the Tenon membrane, a retrobulbar space or has an intrabulbar localization. These patients may have a severe disability, and surgery alone can be complicated due to localization. The aim of this review is to highlight the importance of this unexpected important zoonoses, with special emphasis on the importance within the ophthalmic practice.

    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.

    To determine the clinical profile and outcomes of patients with Pantoea agglomerans endophthalmitis as seen at a tertiary eye care center in India. Retrospective observational case series. Data collected included demographics, history, the initial and final corrected distance visual acuity, details of the ocular and systemic examination, surgeries performed, and the final anatomical outcome. The final corrected distance visual acuity and the anatomical outcome were the outcome measures. Four patients had traumatic endophthalmitis; the fifth developed endophthalmitis after cataract surgery. All patients were men with a mean age of 34.24 ± 23.34 years. Three patients had corneal laceration and traumatic cataract. All patients underwent vitreous sampling with intraocular antibiotic injection with or without lensectomy and corneal wound repair. The visual acuity at presentation ranged from hand motion to perception of light. One patient ended up with phthisis in the affected eye. One patient developed postoperative retinal detachment and underwent successful surgery. The final visual acuity ranged from 20/25 to no light perception. P. agglomerans is a likely source of infection in traumatic and postoperative cases. Though variable, it appears sensitive to common antibiotics. The visual and anatomical prognosis seems fair in most cases. Special care needs to be taken to ensure the organism is not missed, given the rarity of the condition and the isolation techniques required.

    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.

    Lesion area measurement of enamel caries using polarized light microscopy (PLM) is currently performed in a large number of studies, but measurements are based mainly on a mislead qualitative interpretation of enamel birefringence in a single immersion medium. Here, five natural enamel caries lesions are analysed by microradiography and in PLM, and the differences in their histopathological features derived from a qualitative versus a quantitative interpretation of enamel birefringence are described. Enamel birefringence in different immersion media (air, water and quinoline) is interpreted by both qualitative and quantitative approaches, the former leading to an underestimation of the depth of enamel caries mainly when the criterion of validating sound enamel as a negatively birefringent area in immersion in water is used (a current common practice in dental research). Procedures to avoid the shortcomings of a qualitative interpretation of enamel birefringence are presented and discussed. © 2012 The Authors Journal of Microscopy © 2012 Royal Microscopical Society.

    Synoviorthesis was performed in 217 joints from 111 patients suffering from different stages of rheumatoid arthritis (RA). 32P-colloidal chromic phosphate was employed, with an average dose from 6 mCi for large joints (knees) to 0.3 mCi for small peripheral joints such as average dose from 6 mCi for large joints (knees) to 0.3 mCi for small peripheral joints such as the MCP or PIP joints. Satisfactory clinical results were observed in 84% of the cases and no significant side effects resulted after a follow-up period from 1 to 10 years. Striking effects after treatment were observed through histopathological studies (light and electron microscopy) and the use of contrast arthrography. We concluded that radioactive synovectomy with 32P-chromate is a very useful method for the local treatment of RA.

    This paper compares the dinical signs, histopathology, detection of PrPSc protein and PrP genetics of the transmission of BSE to sheep and goats, with the effects of the transmission of natural scrapie from a brain homogenate from a single sheep. After intracerebral and oral inoculations there were similarities in the clinical signs due to the two sources of infection, but there were differences in pathology at the end stage of disease and in the genotypes of the sheep which succumbed to the challenges. The incubation period of BSE was associated with the sheep PrP codon 171 genotype, but the natural scrapie source, despite inducing disease only in known susceptible genotypes, showed no clear association with PrP genotype.

    Abstract To describe the profile of left-sided polymicrobial endocarditis (PE) and to compare it with monomicrobial endocarditis (ME). Among 1011 episodes of left-sided endocarditis consecutively diagnosed in 3 tertiary centers, between January 1, 1996 and December 31, 2014, 60 were polymicrobial (5.9%), 821 monomicrobial (81.7%), and in 123 no microorganism was detected (12.2%). Seven patients (0.7%) were excluded from the analysis because contamination of biologic tissue could not be discarded. The authors described the clinical, microbiologic, echocardiographic, and outcome of patients with PE and compared it with ME. Mean age was 64 years SD 16 years, 67% were men and 30% nosocomial. Diabetes mellitus (35%) were the most frequent comorbidities, fever (67%) and heart failure (43%) the most common symptoms at admission. Prosthetic valves (50%) were the most frequent infection location and coagulase-negative Staphylococci (48%) and enterococci (37%) the leading etiologies. The most repeated combination was coagulase-negative Staphylococci with enterococci (n = 9). Polymicrobial endocarditis appeared more frequently in patients with underlying disease (70% versus 56%, P = 0.036), mostly diabetics (35% versus 24%, P = 0.044) with previous cardiac surgery (15% versus 8% P = 0.049) and prosthetic valves (50% versus 37%, P = 0.038). Coagulase-negative Staphylococci, enterococci, Gram-negative bacilli, anaerobes, and fungi were more frequent in PE. No differences on age, sex, symptoms, need of surgery, and in-hospital mortality were detected. Polymicrobial endocarditis represents 5.9% of episodes of left-sided endocarditis in our series. Despite relevant demographic and microbiologic differences between PE and ME, short-term outcome is similar. PMID:26656328

    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

    The CD3(-)CD4(+) lymphoid variant of hypereosinophilic syndrome is characterized by hypereosinophilia and clonal circulating CD3(-)CD4(+) T cells. Peripheral T-cell lymphoma has been described during this disease course, and we observed in our cohort of 23 patients 2 cases of angio-immunoblastic T-cell lymphoma. We focus here on histopathological (n=12 patients) and immunophenotypic (n=15) characteristics of CD3(-)CD4(+) lymphoid variant of hypereosinophilic syndrome. Atypical CD4(+) T cells lymphoid infiltrates were found in 10 of 12 CD3(-)CD4(+) L-HES patients, in lymph nodes (n=4 of 4 patients), in skin (n=9 of 9) and other extra-nodal tissues (gut, lacrymal gland, synovium). Lymph nodes displayed infiltrates limited to the interfollicular areas or even an effacement of nodal architecture, associated with proliferation of arborizing high endothelial venules and increased follicular dendritic cell meshwork. Analysis of 2 fresh skin samples confirmed the presence of CD3(-)CD4(+) T cells. Clonal T cells were detected in at least one tissue in 8 patients, including lymph nodes (n=4 of 4): the same clonal T cells were detected in blood and in at least one biopsy, with a maximum delay of 23 years between samples. In the majority of cases, circulating CD3(-)CD4(+) T cells were CD2(hi) (n=9 of 14), CD5(hi) (n=12 of 14), and CD7(-)(n=4 of 14) or CD7(low) (n=10 of 14). Angio-immunoblastic T-cell lymphoma can also present with CD3(-)CD4(+) T cells; despite other common histopathological and immunophenotypic features, CD10 expression and follicular helper T-cell markers were not detected in lymphoid variant of hypereosinophilic syndrome patients, except in both patients who developed angio-immunoblastic T-cell lymphoma, and only at T-cell lymphoma diagnosis. Taken together, persistence of tissular clonal T cells and histopathological features define CD3(-)CD4(+) lymphoid variant of hypereosinophilic syndrome as a peripheral indolent clonal T-cell lymphoproliferative

    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

    BACKGROUND Chronic urticaria is characterized by transient, pruritic lesions of varying sizes, with central pallor and well-defined edges, with disease duration longer than six weeks. Its cellular infiltrate consists of neutrophils, lymphocytes and eosinophils. There is a subgroup of patients with eosinophilic or neutrophilic urticaria, resistant to the treatment with antihistamines, but that respond to a combination of antihistamine with other drugs. OBJECTIVE To evaluate the present infiltration in chronic urticaria biopsies and correlate it with the clinical disease activity and response to treatment. METHODS Forty-one patients with chronic urticaria were classified according to the score of severity of the disease, response to treatment and type of perivascular infiltrate. Inflammatory infiltrates were divided in eosinophilic (46.30%), neutrophilic and mixed. RESULTS An association was found between the eosinophilic infiltrate and clinical scores of greater severity (p = 0.002). CONCLUSION This association shows that the eosinophilic inflammatory infiltrates denote high clinical activity, which means more severe and exuberant clinical pictures of the disease. PMID:28099597

    Full Text Available Introduction: The jaw can be affected by several lesions that manifest in the oral cavity, but little is known about their distribution patterns in various populations. Aims and Objectives: This study presents the frequency and distribution of biopsied jaw lesions recorded in Faculty of Dentistry and gathers the information including provisional and final diagnosis of the lesions. Material and Methods: Biopsy of 1938 lesions (2008-2013 was reviewed and 1473 lesions were included in this study. The provisional diagnosis and histopathological validations of lesions were compared. Data on the location of the lesion, as well as patient demographics, were also evaluated. The lesions were divided into three major groups as 1 - developmental/reactive and inflammatory lesions of the jaw, 2 - cystic lesion and 3 - tumor and tumor-like lesions. Statistical Analysis: The variables were recorded and analysed using descriptive statistics. Results and Observations: Three hundred and ninety-six lesions were in Group 1 and periapical granuloma was the most frequent diagnosis. Seven hundred and eighty-nine lesions were in Group 2 and the radicular cyst was the most frequent diagnosis. Two hundred and eighty-eight lesions were in Group 3 and the keratocystic odontogenic tumor was the most frequent. Two hundred and ninety-one biopsied lesions were in disagreement with respect to the diagnoses on clinical and histopathological examination. Conclusion: Consequently, a provisional diagnosis of some of the malignant lesions was reactive, inflammatory, cystic or benign lesions, therefore the importance of evaluation of the specimen is emphasized.

    An unusually large complex odontoma of the maxilla, occupying the entire maxillary sinus with expansion into the floor of the orbit and left nasal fossa, is reported. Although occurrences of complex odontomas are not considered rare, odontomas attaining extremely large sizes, especially involving the entire maxillary sinus with extension to the orbital floor and nasal fossae, are indeed, rare. In this article, the literature is reviewed to identify the common clinical, radiographic, and histologic characteristics of such lesions, and the outcome of treatment is discussed. Complex odontomas occasionally have significant growth potential, especially in the first two decades of life. Early recognition and consideration for surgical excision are key to successful management of this common odontogenic lesion. When odontomas extend beyond the alveolar process into the fascial planes, nasal fossae, paranasal sinuses, and orbits, computed tomography can readily demonstrate the extent and boundaries of the lesion.

    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.

    Full Text Available Introduction: Oral and maxillofacial lesions present a wide spectrum of clinical manifestations ranging from an asympto - matic small lesion to a large destructive one. Several lesions mimic each other in their clinical presentation posing a diag - nostic dilemma. Due to interoperator subjectivity and lack of defined objective diagnostic criteria, histopathological investi - gation, most of the times, plays a vital role in final diagnosis. Many studies have reported the concordance rates among the clinical and histopathological diagnoses of oral lesions, however, there are very few studies which have highlighted the discrepancies in them that have led to drastic changes in the lines of diagnoses and treatment. This institutional retro - spective descriptive study intended to highlight this lacuna by going through histopathological registry to study such cases with discrepancies in clinical and histopathological diagnoses in last 10 years. The aim of this study was to systematically analyze the discrepancies in clinical and histopathological diagnoses of various oral lesions with an emphasis on malig - nant and nonmalignant groups so as to stress the importance of histopathological examination to ultimately minimize the risk of inadvertent inappropriate treatment. Materials and methods: A total of 1570 cases that were reported to our institute over a period of 10 years were evaluated from the histopathology registry. Out of these, 1300 cases met our inclusion criteria. Discrepancies were charted as major and minor discrepancies and discrepancy indices were calculated. Lesions were divided into malignan t and nonmalignant groups and were subjected to d i agnostic-screening test evaluation to assess the discrepancies. Results: Total discrepancy value (discrepancy index obtained was 12.9%, out of which 9.23% showed major discrepancies and 3.69% showed minor discrepancies. Ninety-five percent confidence interval (CI was calculated, and was found in

    The microbiome is the collective term used to describe the bacteria, viruses, fungi and archaea that reside on and in the human body. The majority of these organisms are found within the large bowel. Mounting evidence suggests that changes in the microbiome may be associated with the development of colorectal cancer, a disease which affects 1.3 million people a year worldwide. Using colorectal cancer as an example, this article presents the inter-specialty collaborative approach to microbiome research and discusses the key role that clinical biochemistry is likely to play.

    Full Text Available Introduction. Vascular cognitive impairment is a common yet preventable cause for dementia. It needs high degree of suspicion and appropriate designing of investigatory tools to confirm diagnosis, identify comorbidities, and ascertain the areas of impairment. Commonly DSM-IV criterion is applied for diagnosis and detailed clinical and neuropsychological examination for identifying the specific phenotype is used. Early diagnosis using the mandatory criteria will help in early initiation of disease modifying treatment strategies which can result in partial reversal of vascular changes and arrest of progression. Patients with young onset disease might require genetic characterization for designing more aggressive treatment. Discussion and Conclusion. Dementias as such carry poor course and prognosis resulting in severe Disability Adjusted Life Years (DALYs for patients and caregivers. Therefore, it is mandatory to identify treatable and preventable causes so that man power loss can be reduced.

    Sarcoidosis is a multisystem inflammatory disease characterized by the formation of noncaseating granulomas in various organs and tissues. The majority of patients with systemic sarcoidosis will present with lung and lymph node involvement. In addition, 20% have skin involvement that may be the only manifestation of the disease or may be an important prognostic marker for involvement of other organs. There are multiple forms of presentation of cutaneous sarcoidosis, which may be a true challenge.We report a patient with a one month history of an eruption of skin colored papules. Some were grouped in a symmetrical distribution on the trunk, inner arms, and lumbar region. Pathologic examination revealed an infiltrate in the papillary dermis showing a band of noncaseating granulomas along with disruption of the basal lamina and lichenoid changes. The clinicopathological correlation confirmed the diagnosis of lichenoid sarcoidosis. We consider our case interesting owing to the clinical presentation and the lichenoid distribution of granulomas.

  1. Psoriasis: Epidemiology, clinical features, co-morbidities, and clinical scoring

    Full Text Available On the basis of current evidence derived from hospital-based studies, mostly from North India, the prevalence of psoriasis in adults varies from 0.44 to 2.8%, with a much lower prevalence in children. The peak age at onset in adults is in the third and fourth decade of life, with a slight male preponderance. It is recommended that population-based large epidemiologic studies should be undertaken in different parts of the country for estimating the correct prevalence of psoriasis in general population. Chronic plaque-type psoriasis is the most common morphologic presentation of psoriasis, accounting for more than 90% of all cases. Other morphologic variants that deserve special mention include palmoplantar psoriasis, pustular psoriasis, and recalcitrant psoriasis.For epidemiologic purposes, psoriasis can be classified into early and late onset psoriasis. Psoriasis can be classified on the basis of morphology and extent of involvement into localized and widespread disease.For the purpose of clinical trials, psoriasis may be classified as mild psoriasis, moderate psoriasis, and severe psoriasis. The literature shows that there is a significant risk of psoriatic arthritis (7–48% in patients with plaque-type psoriasis. Hence, it is recommended to evaluate for its presence by detailed history taking and clinical examination, and if necessary, by appropriate radiological investigations. Evidence on the association between plaque-type psoriasis and cardiovascular disease risk factors and ischemic heart disease isinconsistent.On the basis ofavailable evidence, it is prudent to proactively look for metabolic syndrome, dyslipidemia, and obesity, especially in patientswith severe psoriasis (Level 1+ evidence based on systematic reviews and meta-analysis. Based on the current evidence, the psoriasis area severity index appears to be the most valid and reproducible clinical severity score in the management of adult patients with plaque-type psoriasis.

    To compare the RI (resistive index) of renal artery with serum creatinine level and histological change in 50 patients with renal parenchymal disease. To measure RI in each patient, Doppler studies were performed three times in each kidney at the level of the interlobar arteries, and the average value of RI was taken. The study was performed 1 -3 days after renal biopsy and the time interval between blood sampling for serum creatinine and duplex study was also 1 - 3 days. The RI of patients with renal disease was also correlated with patient's age, sex and serum creatinine level, and RI was also correlated with the degree of severity of glomerular, interstitial, and vascular change in the kidneys. Statistical analysis was performed using Student's t test and Pearson's correlation method. The RI of the normal control and renal disease group was 0.566{+-}0.037 and 0.584{+-}0.038, respectively with no statistical significance(p=0.444). In the group with renal disease, there was no significant correlation between RI and a patient's age, sex, and serum creatinine level(p>0.05). RI was not significantly different between predominantly glomerular disease (n=45) and nonglomerular or mixed disease(n=5)(p=0.558), and did not correlate with the severity of glomerular sclerosis, interstitial fibrosis, or atherosclerosis(p>0.05). The authors conclude that RI is not helpful for the diagnosis and differential diagnosis of renal parenchymal diseases and does not correlate with serum creatinine levels. In order to define the role of the RI, further clinical experience with more cases is required.

    In the forensic literature only a few scientific reports are dealing with series of histopathological bone marrow (BM) investigations, mainly concerning changes after drug abuse and alcoholic consumption. In a period of 13 years (1995-2008) we routinely investigated 225 BM specimens from anterior iliac crests taken at forensic autopsies if the cause of death was unclear or vague, septicaemia was suspected or known, in cases of presumed haemorrhagic diathesis or bleeding tendencies, spleens were found to be enlarged or intoxications were suspected or proofed. In 78 cases (34.66%) abnormal histopathologic changes were found. Forty of those revealed neoplastic, mainly haematological diseases, which were unknown during lifetime. Referring to our findings, extraction of post-mortem BM specimens for histopathological investigations should become an essential issue for both the forensic and clinical pathologist.

    Full Text Available ABSTRACT The aim was to report on a case of ossifying fibroma, consisting of a benign fibro-osseous lesion characterized by slow growth and proliferation of fibrous cellular tissue, bone, cement or a combination. A 29-year-old male patient was attended at a hospital, after he had suffered a car accident. During the clinical examination, increased volume in the region of the right side of the mandible was observed, and a fracture in the middle third of the face was suspected. The tomographic examination showed an image suggestive of fracturing of the left-side zygomatic complex, without displacement, and with a well-delimited radiopaque image of the mandible. The patient was sent to a hospital where panoramic radiography, posteroanterior radiography of the face and teleradiography were performed in order to better document the case. An incisional biopsy was performed. Histopathological examination showed the presence of a benign bone lesion suggestive of ossifying fibroma. Surgery was performed in order to completely remove the lesion, with fixation using a reconstruction plate. A new anatomopathological examination confirmed the diagnosis.

    Congenital pulmonary valve stenosis and patent ductus arteriosus are common congenital heart defects in dogs. However, concurrence of atypical pulmonary valve stenosis and patent ductus arteriosus is uncommon. This report describes the anatomic, histopathologic, and echocardiographic features in a dog with concomitant pulmonary valve stenosis and patent ductus arteriosus with atypical pulmonary valve dysplasia that included a fibrous band of tissue. A 1.5-year-old intact female Chihuahua dog weighing 3.3 kg presented with a continuous grade VI cardiac murmur, poor exercise tolerance, and an intermittent cough. Echocardiography indicated pulmonary valve stenosis, a thickened dysplastic valve without annular hypoplasia, and a type IIA patent ductus arteriosus. The pulmonary valve was thick line-shaped in systole and dome-shaped towards the right ventricular outflow tract in diastole. The dog suffered a fatal cardiac arrest during an attempted balloon pulmonary valvuloplasty. Necropsy revealed pulmonary valve dysplasia, commissural fusion, and incomplete opening and closing of the pulmonary valve because of a fibrous band of tissue causing adhesion between the right ventricular outflow tract and the dysplastic intermediate cusp of the valve. A fibrous band of tissue between the right ventricular outflow track and the pulmonary valve should be considered as a cause of pulmonary valve stenosis. Pulmonary valve stenosis and patent ductus arteriosus can have conflicting effects on diastolic and systolic dysfunction, respectively. Therefore, beta-blockers should always be used carefully, particularly in patients with a heart defect where there is concern about left ventricular systolic function.

    Systemic aspergillosis is a manifestation of Aspergillus sp. infection that can result in central nervous system (CNS) involvement with marked alterations in CNS function. Information regarding the clinical presentation and magnetic resonance imaging (MRI) findings in cases of aspergillosis with CNS involvement is lacking, resulting in a need for better understanding of this disease. The primary objectives were to describe the clinical features and MRI findings in dogs with CNS aspergillosis. The secondary objectives were to describe clinicopathologic findings and case outcome. Seven dogs with CNS aspergillosis. Archived records from 6 institutions were reviewed to identify cases with MRI of CNS aspergillosis confirmed with serum galactomannan enzyme immunoassay (EIA) testing, culture, or supported by histopathology. Signalment, clinical, MRI, clinicopathologic, histopathologic, and microbiologic findings were recorded and evaluated. Aspergillosis of the CNS was identified in 7 dogs from 3 institutions. The median age was 3 years and six were German Shepherd dogs. Five dogs had signs of vestibular dysfunction as a component of multifocal neurological abnormalities. The MRI findings ranged from normal to abnormal, including hemorrhagic infarction and mass lesions. Until now, all reported MRI findings in dogs with CNS aspergillosis have been abnormal. We document that CNS aspergillosis in dogs, particularly German Shepherd dogs, can be suspected based on neurologic signs, whether MRI findings are normal or abnormal. Confirmatory testing with galactomannan EIA, urine, cerebrospinal fluid (CSF) or tissue culture should be performed in cases where aspergillosis is a differential diagnosis.

    There have been a number of Swedish studies on human papillomavirus (HPV) typing in men, most of which have used less sensitive HPV-typing techniques. The present study included male patients with genital HPV-induced lesions planned for surgery. Samples were prepared for histopathology and PCR. HPV was detected in 233/253 (92%) and HPV 6 or 11 in 89% of the HPV-positive lesions. There were statistically significant differences regarding morphology (p=0.002), location (p=0.000001) and colour (p=0.005) of the lesions for low- vs. mixed or high-risk HPV types. For example, acuminate lesions were mostly found among men with low-risk HPV types, whereas macular lesions were over-represented among them with mixed or high-risk types. The HPV type distribution is similar to that in earlier studies, but we also found correlations with some clinical parameters.

    To review the research conclusions relating to clinical aspects of syndesmosis, the incidence and prognosis of syndesmosis injuries, and the effectiveness of the history and clinical examination to reliably diagnose ankle syndesmosis injury. Google Scholar search: Syndesmosis paired with incidence, prognosis, history, and examination in turn. There was no time limit for the search. Articles were selected by reading titles, abstracts, and the full article, if indicated, seeking original articles determining these clinical aspects of syndesmosis injuries. Further articles were derived from the references of the primary articles. The prognosis for isolated syndesmosis injuries, including the time to functional recovery, is unknown. The incidence of acute syndesmosis injury in moderate to severe ankle injuries requiring imaging is of the order of 5%. Historical features and special clinical tests of syndesmosis injury have not been proven reliable by clinical studies using evidence-based diagnostic criteria. Acute local tenderness of the anterior inferior tibiofibular ligament will indicate significant syndesmosis injury in only approximately half of nonspecific ankle injuries. There is limited, evidence-based, standard, published literature from which to draw conclusions regarding the validity or reliability of various clinical special tests for syndesmosis injury. Literature assessing the incidence, prognosis, and clinical features is generally not based on definitively confirmed syndesmosis injuries, which is a critical aspect of evidence-based medicine before valid conclusions can be drawn.

    The independence or interdependence of grief and major depression has been keenly argued in relation to recent DSM definitions and encouraged the current study. We report a phenomenological study seeking to identify the experiential and phenomenological differences between depression and grief as judged qualitatively by those who had experienced clinical (n=125) or non-clinical depressive states (n=28). Analyses involving the whole sample indicated that, in contrast to grief, depression involved feelings of hopelessness and helplessness, being endless and was associated with a lack of control, having an internal self-focus impacting on self-esteem, being more severe and stressful, being marked by physical symptoms and often lacking a justifiable cause. Grief was distinguished from depression by the individual viewing their experience as natural and to be expected, a consequence of a loss, and with an external focus (i.e. the loss of the other). Some identified differences may have reflected the impact of depressive "type" (e.g. melancholia) rather than depression per se, and argue for a two-tiered model differentiating normative depressive and grief states at their base level and then "clinical" depressive and 'pathological' grief states by their associated clinical features. Comparative analyses between the clinical and non-clinical groups were limited by the latter sub-set being few in number. The provision of definitions may have shaped subjects׳ nominated differentiating features. The study identified a distinct number of phenomenological and clinical differences between grief and depression and few shared features, but more importantly, argued for the development of a two-tiered model defining both base states and clinical expressions.

    We sought to study the spectrum of oral pathologies presenting clinically with papillary-verrucous features. A 10-year (2007 to 2016) retrospective study of oral papillary lesions was undertaken. All biopsy reports that included a clinical description of papillary or verrucous architecture were retrieved. The data collected included clinical features, size, color, location, histopathologic diagnosis, age, and gender. The study included 137 patients, with a total of 150 lesions. The ages ranged from 10 weeks to 84 years (mean, 49 years). Histopathologically, 60% of cases were human papillomavirus (HPV) related, 19% showed hyperplasia, 11% had hyperplastic candidiasis, 7% were dysplastic or malignant, and 3% were benign of unknown etiology. Among the 7% of lesions diagnosed with dysplasia or malignancy, only 60% were suspected to have malignancy at the time of biopsy. HPV-related lesions and hyperplasia were most frequently found on the tongue (38% and 41%, respectively) and soft palate (21% and 14%, respectively). Hyperplastic candidiasis was most frequently found on the buccal mucosa and tongue (35% and 24%, respectively). Squamous cell carcinoma was found in 1.3% of total lesions and verrucous carcinoma in 1.3%. Of the verrucous or papillary malignant lesions, 50% were found on the gingiva. Most malignant lesions occurred in the 40- to 60-year age group. The results of this study suggest that, because of the wide spectrum of entities presenting clinically with a papillary-verrucous architecture, biopsy is necessary for diagnosis. The clinical presentation allowed for overall accurate diagnosis in only 47% of cases and 60% accuracy in dysplastic or malignant cases. It is of considerable importance to correctly identify those lesions that are HPV related but at the same time to rule out those lesions that are unrelated to HPV to help alleviate a patient's anxiety. Most important, biopsy is mandatory for the recognition of malignant lesions with a papillary

    The aim of this study was to evaluate the association of primary tumour {sup 18}F-fluorodeoxyglucose (FDG) uptake with clinical, histopathological and molecular characteristics of breast cancer patients scheduled for neoadjuvant chemotherapy. Second, we wished to establish for which patients pretreatment positron emission tomography (PET)/CT could safely be omitted because of low FDG uptake. PET/CT was performed in 214 primary stage II or III breast cancer patients in the prone position with hanging breasts. Tumour FDG uptake was qualitatively evaluated to determine the possibility of response monitoring with PET/CT and was quantitatively assessed using maximum standardized uptake values (SUV{sub max}). FDG uptake was compared with age, TNM stage, histology, hormone and human epidermal growth factor receptor 2 status, grade, Ki-67 and molecular subtype in univariable and multivariable analyses. In 203 tumours (95 %) FDG uptake was considered sufficient for response monitoring. No subgroup of patients with consistently low tumour FDG uptake could be identified. In a univariable analysis, SUV{sub max} was significantly higher in patients with distant metastases at staging examination, non-lobular carcinomas, tumours with negative hormone receptors, triple negative tumours, grade 3 tumours, and in tumours with a high proliferation index (Ki-67 expression). After multiple linear regression analysis, triple negative and grade 3 tumours were significantly associated with a higher SUV{sub max}. Primary tumour FDG uptake in breast cancer patients scheduled for neoadjuvant chemotherapy is significantly higher in tumours with prognostically unfavourable characteristics. Based on tumour characteristics associated with low tumour FDG uptake, this study was unable to identify a subgroup of patients unlikely to benefit from pretreatment PET/CT. (orig.)

    Full Text Available The article is devoted to the study of clinical and anamnestic features of hepatic steatosis in children. The results of a comparative analysis of survey data of patients with evidence of hepatic steatosis and patients without steatosis were shown. The presence and degree of hepatic steatosis was found using FibroScan-touch-502 by measuring controlled attenuation parameter (CAP. The features of lifestyle and nutrition of children with steatosis were determined: hypodynamic lifestyle, the prevalence of fast food habits, insufficient consumption of liquid. It was established that hepatic steatosis is closely associated with obesity and hypothalamic disorders, increased both blood pressure and serum levels of atherogenic lipids.

    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.

    Enterovirus 71 (EV71) is a neurotropic pathogen that causes hand, foot, and mouth disease. While infection is usually self-limiting, a minority of patients infected with EV71 develop severe neurological complications. In humans, EV71 has been reported to utilize the scavenger receptor class B, member 2 (SCARB2) as a receptor for infectious cellular entry. In this study, we define the pathological features of EV71-associated disease as well as the distribution of EV71 antigen and SCARB2 in human fatal cases and a mouse model. Histopathologically, human fatal cases showed severe central nervous system (CNS) changes, mainly in the brainstems, spinal cords, and thalamus. These patient further exhibited pulmonary edema and necrotic enteritis. Immunohistochemical analysis of human fatal cases demonstrated that EV71 antigen and SCARB2 were observed mainly in neurons, microglia cells and inflammatory cells in the CNS, and epithelial cells in the intestines. However, skeletal muscle tissue was negative for EV71 antigen. In a mouse model of EV71 infection, we observed massive necrotic myositis, different degrees of viral diseases in CNS, and extensive interstitial pneumonia. In mice, EV71 exhibits strong myotropism compared to the neurotropism seen in humans. EV71 antigen was detected in the spinal cord and brainstem of mice. However, there was no clear correlation between mouse SCARB2 and EV71 antigen distribution in the mouse model, consistent with previous results that SCARB2 functions as a receptor for EV71 in humans but not mice. The EV71-induced lesions seen in the mouse model resembled the pathological changes seen in human samples. These results increase our understanding of EV71 pathogenesis and will inform further work developing a mouse model for EV71 infection.

    Full Text Available Background: Salivary gland neoplasm is one of the rare neoplasm. The frequency of this neoplasm is lower than 2% of all type of tumors in human. Malignant salivary gland tumor comprises 6% of all head and neck tumors. Data about salivary gland carcinoma are still limited. The aim of this study was to determine the frequency of malignant salivary gland based on the patients’ age, gender, site of lesion and histopathology type. Methods: This study was conducted descriptively. There were 97 subjects found from histopathological form that had been examined in Department of Anatomical Pathology, Dr. Hasan Sadikin General Hospital in 2009–2012. Total sampling technique was used and all data about patients’ age, gender, site of lesion and histopathology type were collected and analyzed. Results: Of 97 cases, age group 50–59 years old had the highest frequency (29%. The prevalence in male was more frequent than female with male:female ratio was 1.4:1. The most common site of carcinoma was found in parotid gland (45%. Mucoepidermoid carcinoma was the most common histopathology type found in this study (28%. Conclusions: Salivary gland carcinoma is still a rare malignant case in Dr. Hasan Sadikin General Hospital. Carcinoma in parotid gland was the most common site and mucoepidermoid carcinoma was the most common histopathology type.

    Neuropsychiatric (NP) involvement is a poorly understood manifestation of SLE. We studied post-mortem histopathology in relation to clinical NPSLE syndromes and complement deposition in brains of NPSLE and SLE patients and controls. Furthermore, we investigated the correlation between cerebral post-mortem histopathology and ex vivo 7 T MRI findings in SLE and NPSLE. A nationwide search for autopsy material yielded brain tissue from 16 NPSLE and 18 SLE patients. Brains obtained from 24 patients who died of acute cardiac events served as controls. Apart from a histopathological evaluation, paraffin-embedded cortical tissue was stained for components of the classical, lectin and terminal complement pathways. Diffuse vasculopathy, microinfarction, macroinfarction, vasculitis and microthrombi occurred significantly more often in NPSLE than SLE patients and were absent in controls. Focal vasculopathy was found in both SLE patients and controls. Complement deposition was strongly associated with both SLE and NPSLE, but not with controls (P < 0.001). Microthrombi were found uniquely in NPSLE and were associated with C4d and C5b-9 deposits (P < 0.05). A 7 T MRI was unable to detect most small vessel injury that was visible histopathologically. Our study demonstrates that histopathological lesions in NPSLE represent a continuum, ranging from non-specific lesions such as focal vasculopathy, to more specific lesions including C4d- and C5b-9-associated microthrombi and diffuse vasculopathy related to clinical syndromes defining NPSLE. Complement deposition may be a key factor in the interaction between circulating autoantibodies and thromboischaemic lesions observed in NPSLE. Therefore, complement inhibition may have novel therapeutic potential in NPSLE. © The Author 2016. Published by Oxford University Press on behalf of the British Society for Rheumatology.

    There is no easy road map for venous malformations (VMs) of the head and neck according to which treatment modality can be chosen. The purpose of this study was to identify different types of VMs of the head and neck based on clinical, histopathology, MRI, and venography findings that help in specification of different treatment modalities. Sixty-nine patients with VMs of the head and neck were included in this study. Our results proposed a diagnostic approach for VMs of the head and neck. MRI, venography, and clinical examination had important impact in decision-making, whereas histopathology had no impact. A management approach has been suggested for each type and its subtypes.

    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.

    To investigate and summarize the clinical features and comorbidities of Asperger syndrome (AS) in children and to provide a theoretical basis for improving the understanding and diagnosis of AS. Inquiry of medical history, physical examination, behavioral observation, psychiatric examination, questionnaire survey, and the Wechsler Intelligence Scale were used to summarize and analyse the clinical data of 95 children with AS, including chief complaint, symptoms, perinatal and familial conditions, family genetic history, and common comorbidities. AS was more common in male children, with hyperactivity, inattention, and social withdrawal as frequent chief complaints. The main clinical manifestations included poor communication skills (95%), restricted interest (82%), repetitive and stereotyped patterns of behavior (77%), semantic comprehension deficit (74%), and indiscipline (68%). Verbal IQ was higher than performance IQ in most patients. The comorbidities of AS included attention deficit hyperactivity disorder (ADHD) (39%), emotional disorder (18%), and schizophrenia (2%); emotional disorder was more common in patients aged 13-16 years, while ADHD was more common in patients aged 7-16 years. Among these patients, 61% had fathers with introverted personality, 43% had mothers with introverted personality, and 19% had a family history of mental illness. AS has specific clinical manifestations. It is essential to know more about the clinical features and comorbidities of AS, which is helpful for early identification and diagnosis of AS.

    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.

    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.

    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.

    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.

    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.

    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.)

    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.

    The structure of the nail unit is complex and many dermatologists and dermatopathologists have an incomplete understanding of it. Familiarity with the anatomy and histology of this unit, however, is a key factor in improving the diagnostic yield of nail biopsy. Inflammatory or infectious conditions that affect the nail can have a marked impact on a patient's quality of life. A wide-ranging variety of tumors can also develop in this region and they may be life-threatening or require surgery that will result in functional defects. The author reviews the anatomy and histology of the nail unit as well as the basic histopathologic findings in the most common conditions affecting the nails.

    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.

    Nemaline myopathy (NM) is a rare congenital myopathy of great heterogeneity, characterized by the presence of rods in the cytoplasm of muscle fibers. This study aimed to summarize and analyze retrospectively the clinicopathological features of 28 patients with NM. Among the 28 patients, 15 were classified as of the typical congenital type, manifested as lower- or four-limb weakness as the first symptom and slowly progressive course. Six patients were classified as of childhood onset type, with lower-limb weakness and progressive course. Seven patients were classified as of the adult onset type, with rapidly progressive course and obvious muscle atrophy. Patient's 1, 16 and 23 had rapid clinical progression. On follow up, the three patients showed respiratory failure. Limb weakness in all patients was proximal‑dominant. Hypotonia was observed in most patients. High arched feet were also observed as dysmorfic features. In all patients, the creatine kinase (CK) level was normal or mildly elevated, and electromyography revealed myogenic changes. Nemaline bodies were observed under a light microscope in more than half of the patients' muscle fibers, and especially in type I fibers. All patients showed fiber type I predominance and atrophy. Modified Gömöri trichrome staining showed characteristic purple‑colored rods. Muscle electron microscopy revealed the presence of high electron‑dense nemaline bodies around the nucleus, and of a disorganized myofibrillar apparatus, with broken myofilaments and irregular myofibrils and Z lines. The 28 patients with NM shared a number of clinical features, such as proximal limb weakness, reduced deep tendon reflex and dysmorfic features. Differences were also observed between the three types of patients, with regards to course progression, disease severity and respiratory failure. In conclusion, patients with NM showed great clinical heterogeneity. The diagnosis of NM was mainly based on the muscle biopsy.

    Full Text Available Background: Tonsillar diseases are common in paediatric and adult otolaryngological practice. These diseases require tonsillectomy. Specimens are subjected to histopathology routinely in my institution for fear of infections and tumour without consideration for risk factors. The financial burden is on the patients and waste of histopathologist′s man hour because other specimens are left un-attended. This study aims to find out the necessity of routine histopathology of tonsil specimens. Materials and Methods : A 2 year retrospective review of the histopathological results of two (paediatric and adult groups of 61 patients managed for tonsillar diseases at the ENT UNIT of Jos University Teaching Hospital from July 2005 to June, 2007. Data extracted included biodata, clinical features and histopathological diagnosis. Result : The 61 patients comprise 35 children and 26 adults. The youngest and oldest paediatric patients were 1 year and 3 months and 16 years respectively, a range of 1 year 3 months to 16 years. The youngest and oldest adults were 17 and 50 years with a range of 17-50 years. Groups mean ages were 5.1 and 28.5 years. The gender ratios were 1:2.7 and 1:1.9 respectively. One adult was HIV positive. The histopathological diagnosis were chronic nonspecific tonsillitis in 10(16.6%, follicular tonsillitis in 23(38.3%, chronic suppurative tonsillitis in 10(16.6%, lymphoid hyperplasia in 18(30.0% and lymphoma in 1(1.0% respectively. Conclusion : Histopathologic request for tonsillectomy specimens should be based on certain risk factors with consideration of the cost to patients and to spare the histopathologist′s man hour.

    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

    Koi herpesvirus (KHV) is the aetiological agent of an emerging disease (KHVD) associated with mass mortalities in koi and common carp and reported from at least 30 countries. We report the first detection of KHV from koi in Iran using clinical, histopathological and molecular studies. KHV-infected fish showed reduced swimming activity, sunken eyes and increased mucus production on skin and fins. On post-mortem examination, gill necrosis was observed in the majority of fish. Histopathologically, the gill showed diffuse necrosis of the branchial epithelial cells. Margination of chromatin was detected in gills, kidney, heart, spleen, intestine and brain. In addition, sequence analyses of the TK gene, ORF 136 and marker I and II, demonstrates that Iranian KHV isolates were identical and classified as variant A1 of TUSMT1 (J strain) and displayed the I(++) II(+) allele of this Asian genotype.

    The anaplastic ganglioglioma (AG) is the high-grade counterpart of ganglioglioma, a rare mixed tumor composed of neuronal/ganglion and glial cells. We describe the histopathology and immunohistochemistry in 7 cases of AG and correlate them with the clinical and radiological features. Our AG patients correspond to 2.5% of the central nervous system tumor patients evaluated in our institution. The mean age at presentation was 25.7 years, with a male predominance. The most common clinical presentation was generalized tonic-clonic seizures (3/7 cases), in correlation with frequent cortical/subcortical location (6/7 cases). Histopathologically, all our cases showed high-grade features in glial (glial fibrillary acid protein-positive) and neuron-ganglion cells (synaptophysin, PGP-9.5, neurofilament, NSE and CD56-positive), as well as moderate cellularity, frequent mitotic figures and a Ki-67 labeling index >5%. All our patients had poor survival. We found that a typical histopathological and immunohistochemical profile is constant and can be useful in early diagnosis of these aggressive neoplasms.

    2004-01-01

    Background Diffuse panbronchiolitis (DPB) was originally and is still primarily reported in Japan, rarely in other countries. As macrolide therapy is effective for this disease with once dismal prognosis, familiarity with its clinical features is urgently needed, especially for clinicians outside Japan. The objectives of this study were to investigate the clinical features of DPB in a Chinese population and propose diagnostic procedures that will lead to increased awareness of this treatable disease among clinicians, ultimately allowing for more rapid diagnosis. Methods After a literature review, the clinical features of DPB were histopathologically confirmed in a series of 9 cases either by open lung biopsy or video-assisted thoracic surgical biopsy, resulting in the largest series of confirmed DPB cases in a non-Japanese population. Here, the cases are retrospectively described and diagnostic procedures are discussed.Conclusions Although its clinical features may vary with disease course and ethnic populations, most cases of DPB can be diagnosed or suggested according to clinical diagnostic criteria. However, underdiagnosis as a result of unfamiliarity with its clinical features and diagnostic criteria prevails. If difficulty in diagnosis arises, the diagnosis should be based on clinicopathological features and the exclusion of other diseases. Few cases can be confirmed by transbronchial biopsies; in these cases, either an open-lung biopsy or a video-assisted thoracic surgical lung biopsy should be recommended.

    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.

    2017-02-01

    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.

    2014-05-01

    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.

    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 Background and Aims: Castleman′s disease (CD is a rare disease of lymph node with two identified forms - the hyaline vascular (HV type or angiofollicular type and plasma cell (PC type. It usually presents as localized or systemic lymphadenopathy or even as extra nodal mass and may give rise to several differential diagnoses. Fine needle aspiration cytology (FNAC, as the initial investigation, may be misleading. Excision biopsy usually gives the diagnosis. This study analyzes the clinical, cytological and histological features of CD of HV type Materials and Methods: All the cases of CD reported between 2001 and March 2008 have been reviewed. Cytology and histopathology slides of all cases were reviewed by two reporting pathologists independently and the clinical records were analyzed. Result: We had five cases of CD all of which presented as cervical lymphadenopathy of 1 to 5 cms in young patients. Patients were mostly asymptomatic with all relevant investigations within normal limits. The cytology findings mostly showed a predominance of small lymphocytes with capillary fragments. On excision biopsy, all cases were diagnosed as CD of HV type. Conclusion: CD should be kept as a differential of lymphadenopathy, especially in asymptomatic and young patients.

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.

    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

    Conclusion: Although the degree of abnormality in colposcopic findings can be predicted by the vascular patterns of the lesion, the major advantage of colposcopy is to outline the most suspicious lesion for histologic diagnosis by directed biopsy, which is the mainstay in establishing the correct diagnosis. Colposcopy is valuable in the detection of early cancerous lesions. However the final diagnosis must rely on a meticulous histopathological examination by an expert pathologist.

    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.

    Vein of Galen malformations (VOGMs) are rare and complex congenital arteriovenous fistulas. The clinical and radiological features of VOGMs and their relation to clinical outcomes are not fully characterized. To examine the clinical and radiological features of VOGMs and the predictors of outcome in patients. We retrospectively reviewed the available imaging and medical records of all patients with VOGMs treated at the University of California, San Francisco between 1986 and 2013. Radiological and clinical features were identified. We applied the modified Rankin Scale to determine functional outcome by chart review. Predictors of outcome were assessed by χ(2) analyses. Forty-one cases were confirmed as VOGM. Most patients (78%) had been diagnosed with VOGM in the first year of life. Age at treatment was bimodally distributed, with predominantly urgent embolization at <10 days of age and elective embolization after 1 year of age. Patients commonly presented with hydrocephalus (65.9%) and congestive heart failure (61.0%). Mixed-type (31.7%) VOGM was more common in our cohort than purely mural (29.3%) or choroidal (26.8%) types. The most common feeding arteries were the choroidal and posterior cerebral arteries. Transarterial embolization with coils was the most common technique used to treat VOGMs at our institution. Functional outcome was normal or only mildly disabled in 50% of the cases at last follow-up (median=3 years, range=0-23 years). Younger age at first diagnosis, congestive heart failure, and seizures were predictive of adverse clinical outcome. The survival rate in our sample was 78.0% and complete thrombosis of the VOGM was achieved in 62.5% of patients. VOGMs continue to be challenging to treat and manage. Nonetheless, endovascular approaches to treatment are continuing to be refined and improved, with increasing success. The neurodevelopmental outcomes of affected children whose VOGMs are treated may be good in many cases. Published by the BMJ

    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

    Objective To discuss thepathogenesis, etiology, clinical manifestations, diagnosis, treatment and prognosis of right-sided infective endocarditis (RIE) . Methods To investigate retrospectively the clinical data of patients with RIE admitted in our hospital from Jan 1985 to Dec 2000.Results There were 17 cases of RIE (12 male, 5female, mean age 22 years), among which 7 with congenital heart disease, 1 with pacemaker implantation and 9 with a history of intravenous drug abuse but without underlying heart disease. Fever and multiple pulmonary emboli were the major clinical manifestations. Blood cultures were positive in 8 cases with Staphylococcus aureus as the predominant microorganism. Echocardiography detected right heart vegetations in all cases, with tricuspid valve as the structure most frequently affected. Most patients were successfully treated with antimicrobials. The outcome was favourable, with a mortality of 11.8 % . Conclusions The clinical features of RIE are different from that of left-sided infective endocarditis (LIE) . Echocardiography plays an important role in the diagnosis of RIE.

    Because it is difficult to distinguish between focal takotsubo cardiomyopathy and aborted myocardial infarction, there is little information about the prevalence and clinical features of focal takotsubo cardiomyopathy. Our cardiac catheterization databases were queried to identify patients with focal takotsubo cardiomyopathy and other types of takotsubo cardiomyopathy. We defined focal takotsubo cardiomyopathy as hypo-, a- or dyskinesis in both anterolateral and septal segments without obstructive coronary artery disease explaining the wall motion abnormality. A total of 10 patients were diagnosed with focal takotsubo cardiomyopathy. The control group comprised patients with takotsubo cardiomyopathy with apical, mid-ventricular, or basal ballooning. Clinical features and in-hospital outcomes were compared between patients with focal takotsubo cardiomyopathy and those with other types of takotsubo cardiomyopathy. Among the 144 patients with takotsubo cardiomyopathy, the apical, mid-ventricular, basal, and focal types occurred in 85 (59.0%), 49 (34.0%), 0 (0%), and 10 patients (6.9%), respectively. The left ventricular ejection fraction was significantly higher in the focal group compared with the apical and mid-ventricular group (56±13 vs. 45±13 vs. 46±12%, P=0.03). In-hospital outcome was not significantly different among the 3 groups. Focal takotsubo cardiomyopathy is not rare. Biplane left ventriculography is useful for its diagnosis.

    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 AND OBJECTIVES Abnormal Uterine Bleeding (AUB is a very frequent gynaecological complaint and occurs across the entire age spectrum, approximately 75000 hysterectomies are carried out each year with 30% of these for menstrual problems alone. These menstrual aberrations occur more commonly at extremes of reproductive life. The introduction of hysteroscopy has opened a new dimension in evaluation of patient with AUB replacing the blind technique of Dilatation and Curettage. The present study was undertaken to know the accuracy of various tests with Histopathology. MATERIALS AND METHODS The present prospective study was carried out on 100 patients from reproductive, perimenopausal and postmenopausal age group with abnormal uterine bleeding in Dr. B. R. Ambedkar Medical College and Hospital. RESULTS In the present study, in relation to histopathological examination, clinical findings and hysteroscopy had better accuracy (72% as compared to ultrasound findings (41% in diagnosis of abnormal uterine bleeding. CONCLUSION Hysteroscopy guided biopsy and histopathology complements each other in the evaluation of patient with abnormal uterine bleeding for accurate diagnosis and further treatment.

    Hippocampal sclerosis (HS) is a common pathology in MTLE, patients may show different surgical outcomes and clinical features. The 2013 ILAE classification subdivides HS into 3 types (HS type 1: severe neuronal loss and gliosis predominantly in CA1 and CA4 regions; - HS type 2: CA1 predominant; HS type 3: CA4 predominant) and includes "gliosis only, as no-HS". The association of clinical and electrophysiological findings with different HS types has not been reported previously in detail. 48 patients who had undergone temporal lobectomy with amygdalohippocampectomy due to mesial TLE-HS between February 2014 and February 2016 were included. The patients were divided into five groups: patients with HS ILAE type 1, HS ILAE type 2, HS ILAE type 3, FCD type IIIa, or gliosis/no HS. The correlation between HS ILAE types and clinical/EEG findings in patients with MTLE due to HS was investigated. Of the 48 patients 30 were male. In 23 patients, the resection was on the left side (48%). Three patients had only gliosis, 25 patients had HS ILAE type 1, 7 had HS ILAE type 2, and 4 had HS ILAE type 3. Nine of the 48 patients had cortical lamination abnormalities in the temporal lobe associated with HS (FCD type IIIa). All patients were seizure free for early follow up. There was no association between type of HS in terms of duration of epilepsy, onset age of epilepsy, lateralized or localized semiological findings, or interictal/ictal EEG findings. Family history of epilepsy or SGTCSs were statistically more frequent in patients with types 2 and 3 HS and status epilepticus was more frequent in patients with HS-FCD type IIIa. The patients with HS types 2 and 3 have more frequent SGTCS or status epilepticus as well as increased family history of epilepsy. These findings can be helpful in understanding the epileptogenicity-prognoses of HS. Copyright © 2016 Elsevier B.V. All rights reserved.

    2012-12-01

    Full Text Available Diseases of the oral cavity may be either a reflection of system or cutaneous diseases or can be seen as a primary oral lesion. These lesions are inflammatory reactions due to miscellaneous mechanisms, ulceration or erosion, reactive proliferative nodules, precancerous or neoplastic diseases. In this study, microscopic features of the most common diseases, together with their differential diagnosis are discussed. Some of the diseases of the oral cavity have overlapping histopathological findings. In these conditions, ancillary methods such as immunoflourescence or immunohistochemistry can be performed. Deep biopsies from representative areas are essential for proper histopathological diagnosis. Moreover, informing the pathologist about the exact anatomic localization of the biopsy, as well as the clinical findings of the lesion is crucial for a better approach.

    To assess the spectrum of causes, clinical features, differences between disease phases, and prognosis of extrinsic allergic alveolitis (EAA). Patients with EAA diagnosed at Peking Union Medical College Hospital from August 1983 to May 2007 were analyzed retrospectively. Their medical records were examined to gather clinical, laboratorial, radiological, and histopathological data. Patients were divided to three phases (acute, subacute, and chronic) according to clinical presentations. Follow-up data regarding treatment response, subsequent radiological and pulmonary function studies, and clinical outcomes were collected. A total of 21 cases were enrolled. Among them, 11 were subacute, 10 were chronic. The most common exposure was pet birds (6 cases, 28.6%). The primary abnormality of pulmonary function was restriction and/or reduction in diffusing capacity (12 cases, 63.2%). The most common findings on high-resolution computed tomography (HRCT) were ground-glass opacities (13 cases, 68.4%) and centrilobular nodules (8 cases, 42.1%). Airway obstruction in pulmonary function test, emphysema, lung cysts, and fibrosis on HRCT were more frequently seen in chronic than in subacute patients, though the differences were not statistically significant. Bronchoalveolar lavage fluid (BALF) showed lymphocytosis. The total cell count and the percentage of neutrophils were significantly higher in subacute than in chronic patients (P<0.05). Nonnecrotizing granulomas were seen in 8 (47.1%) cases. Improvement or normalization in symptoms, radiography, and pulmonary function test after treatment were seen in all 18 patients with available follow-up data. Five patients recurred. The characteristic abnormalities of pulmonary function, findings on HRCT, and pathology are essential for all phases of EAA, and the atypical manifestations such as obstruction and fibrosis can also be present frequently, particularly in chronic cases. Differential cell counts of BALF are related to the phase

    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.

    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.

    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

    The purpose of this study was to describe the breast ultrasonography (US) features and to investigate whether performing a core biopsy is warranted in young women having palpable solid breast masses. A total of 76 solid palpable masses in 68 consecutive women (≤25 years old) underwent tissue diagnosis by percutaneous core biopsy. Two radiologists, who were blinded to the clinical history and histopathology, independently evaluated the US features according to Breast Imaging-Reporting and Data System (BI-RADS) lexicon. The frequency of benign and malignant descriptor terms that were used to characterize the lesions were compared to the final pathology. All 76 palpable solid masses yielded benign pathology. On the US, the shape of the mass was described by radiologists 1 and 2 as oval or round (63.2% and 71.1%), margin as circumscribed (68.4% and 77.6%) and orientation as parallel (85.5% and 90.8%); the frequency of using all three benign descriptors was 61.8% and 68.5%, respectively. Suspicious descriptors were used less frequently by radiologists 1 and 2 including irregular shape (9.2% and 13.1%), non-circumscribed margin (31.6% and 22.4%) and non-parallel orientation (14.5% and 9.2%); the frequency of using all three suspicious descriptors was 9.2% and 11.8%, respectively. Despite the variable US features, breast malignancy seems extremely low in 25 years or younger women for palpable breast lesions. Using the BI-RADS lexicon, US accurately predicted benignity in about two thirds of our patients, supporting US surveillance as a safe alternative to invasive tissue sampling in this setting.

    Full Text Available Background: Tumor necrosis factor-alpha (TNFα is an important inflammatory mediator in psoriasis and several genetic polymorphisms of this cytokine have been reported. Majority of studies have focused on the increased G- A polymorphism at the -308 position in psoriasis. There has been no comprehensive study evaluating the genetic polymorphisms, TNFα expression in the skin and histopathology. We are undertaking this study to outline TNFα genetic polymorphisms, its skin expression and histopathological correlation to help determine its role at the genetic and protein level. Materials and Methods : 112 patients of psoriasis and 243 healthy controls were included in this prospective study. 5 ml of peripheral blood was collected to study the TNFα genetic polymorphisms by polymerase chain reaction and restriction fragment length polymorphism analysis. Histopathological analysis of biopsies from the 112 patients were done using visual analogue scale and correlated with the findings. 61 of these cases were analyzed for TNFα expression by immunohistochemistry. The results of study were statistically analyzed using SPSS 13.0 statistical package program. Results: A strong association of TNFα -308 G/A polymorphism in psoriasis cases was detected. The A allele of the TNFα -308 G/A polymorphism occurs rarely in the Indian population, however there is an over representation of this allele in psoriatic patients. There was no association seen between TNFα genotype and histopathological severity of psoriasis. Conclusion: The study emphasized the central role of TNFα in the pathogenesis of psoriasis. TNFα genotyping may be helpful in identifying subjects in whom anti-TNFα therapeutic strategies may be tried.

    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

    The oral mucositis is a main side effect of radiotherapy on head and neck, initiating two weeks after the beginning of the treatment. It is characterized by sensation of local burning to intense pain, leading in several cases, to the interruption of the treatment. The purpose of this work is to review the main published studies that discuss the clinical, biological and histopathological features of oral mucositis induced by radiation therapy and to describe the main approaches recommended to prevent or to treat it. Although the clinical features of mucositis are intensively described in the literature, few studies address the histopathological alterations in oral mucositis and only recently, its biological processes have been investigated. The biological mechanisms involved in the radiation tissue damage have been only recently discussed and there is no consensus among treatment modalities. Yet, the progressive knowledge in the histopathology and biological characteristics of oral mucositis probably will lead to more effective in prevention and control strategies. (author)

    Clear cell tumors of the skin are observed in a wide variety of benign and malignant conditions with different histogenesis, sharing the presence of cells with abundant clear cytoplasm. Herein, we report the clinicopathologic features of a healthy young patient affected by asymptomatic, eruptive and disseminated, benign clear cell dermal tumors since early infancy. Neither family history nor genetic testing and counseling provided further useful information. The lesions were mostly confined to the face and lower left extremity with pink teleangiectatic papules and small nodules. Over a 4-year period, a total of 16 different cutaneous lesions were biopsied and histopathologic and immunohistochemical studies carried out; an additional lesion was also removed for electron microscopy examination. Histopathology evidenced multiple perivascular growths of spindle to oval and round cells intermingled with clear/granular cells throughout the dermis, with prominent desmoplasia and numerous capillary-like vessels with focal hemangiopericytoma-like features. Immunohistochemical neoplastic cells were uniformly positive for h-caldesmon and focally smooth muscle α-actin and CD13 indicating myoid differentiation whereas the consistent diffuse cytoplasmic staining for lysosome antigen, such as CD68PG-M1 and NKI/C3 along with the ultrastructural findings supported the view of a lysosome-mediated apoptotic process. The differential diagnosis with other clear cell cutaneous neoplasms is discussed.

    Objectives While gastritis and esophagitis are well studied in children, there is very limited literature on duodenitis in children. We aimed to assess the prevalence, etiology, clinical, endoscopic, and pathological features in a large cohort of unselected children with duodenitis. Methods We reviewed the pathology reports of all upper endoscopies performed at our institution over 5 years to identify children with duodenitis. Biopsy sections were reviewed to confirm the diagnosis of duodenitis. Demographic, clinical, endoscopic data and presence of associated gastritis and esophagitis were noted in all children with duodenitis. Etiology of duodenitis was correlated with the patient's clinical diagnosis. Results Out of 2772 children who had endoscopy, 352 had duodenitis with the prevalence rate of 12.7%. Gastritis was seen in 64% of children with duodenitis compared with 46% of children without duodenitis (P < 0.001). Common indications for endoscopy in children with duodenitis were abdominal pain, positive celiac serology and diarrhea. The most common etiology was celiac disease (32%), followed by Crohn's disease (13%), ulcerative colitis (3%), and Helicobacter pylori infection (6%). In 63% of cases, endoscopic appearance of duodenum was normal. Cryptitis, villous changes and cellular infiltration were noted on histology. Conclusions Prevalence of duodenitis is 12.7% in children undergoing endoscopy. Celiac disease and inflammatory bowel disease are common causes of duodenitis. Associated gastritis is common in children with duodenitis and correlation of endoscopic appearance with histology is poor. PMID:26252915

    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

    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 Mycoplasma pneumoniae is one of the most common causes of community-acquired pneumonia in children and young adults. The incidence of fulminant M. pneumoniae pneumonia (MPP is relatively rare despite the high prevalence of M. pneumoniae infection. This literature review highlights the clinical features of fulminant MPP by examining the most recent data in epidemiology, clinical presentation, pathogenesis, and treatment. Fulminant MPP accounts for 0.5-2% of all MPP cases and primarily affects young adults with no underlying disease. Key clinical findings include a cough, fever, and dyspnea along with diffuse abnormal findings in radiological examinations. Levels of inflammatory markers such as white blood cells (WBC and C-reactive protein (CRP are elevated, as well as levels of lactate dehydrogenase (LDH, IL-18, AST, and ALT. The exact pathogenesis of fulminant MPP remains unclear, but theories include a delayed hypersensitivity reaction to Mycoplasma pneumoniae and the contribution of delayed antibiotic administration to disease progression. Treatment options involve pairing the appropriate anti-mycoplasmal agent with a corticosteroid that will downregulate the hypersensitivity response, and mortality rates are quite low in this treatment group. Further research is necessary to determine the exact pathogenesis of severe and fulminant types of MPP.

    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

    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

    Full Text Available Bacground/Aim. Sjögren's syndrome is a chronic autoimmune systemic disease characterized by polyglandular tissue destruction, leading to keratoconjunctivitis sicca and xerostomia. These patients have 44-fold increased risk of developing salivary gland lymphoma, of which 80% are marginal zone (MALT type. Having in mind that criteria for distinguishing benign lymphoepithelial lesions from MALT lymphoma are obscure, the aim of this study was to provide practical information that could be integrated into diagnostic practice. Methods. Among 32 parotidectomies, 27 cases were identified as having benign lymphoepithelial disorders and 5 cases low grade MALT lymphoma. Histological sections were stained routinely with hematoxylin and eosin (H&E and special stains. Immunohistochemical study was performed by LSAB2 method, by using primary antibodies for CD20, CD3, Kappa and Lambda light chains and Cytokeratin (Dako Denmark. Results. The 27 patients with Sjögren's sialoadenitis (22 women and 5 men, and 5 patients with MALT lymphoma (only women were included in this analysis. According to the Ann Harbor Classification, all patients with MALT lymphoma had stage IE. Both groups of patients had an indolent clinical course, except permanent, rapid parotid enlargement in the patients with MALT lymphoma. Histologically, the periductal lymphoid infiltrate, gradually extended to the acini, completely replacing them by a sea of polyclonal lymphocytes, immunoblasts, germinal centers and plasma cells (confirmed immunohistochemically, but sparing the ducts and preserving lobular appearance. The histological feature of salivary gland MALT lymphoma included heterogeneous B-cell infiltrate that totally or subtotally had effaced the normal glandular structure. Malign lymphoepithelial lesions, representing infiltration of the ductal and epithelial structures by monoclonal neoplastic Bcells, positive for CD20, were highlighted by antibody to cytokeratin.

    Esophageal eosinophilia is classified as either eosinophilic esophagitis (EoE) or proton-pump inhibitor-responsive esophageal eosinophilia (PPI-REE), depending on the response to PPI treatment. The aim of this study was to compare the clinical, endoscopic, and histopathological findings of EoE and PPI-REE in Japanese patients. In addition, the characteristics of these cases were compared with those of reflux esophagitis (RE) cases. Eleven patients diagnosed with EoE, 16 with PPI-REE, and 39 with RE, who were all consecutively examined from 2005 to 2015 at Shimane University Hospital, were enrolled. Clinical, endoscopic, and histopathological esophageal findings in these groups were retrospectively examined and compared. The differences in the clinical characteristics of EoE and PPI-REE were not remarkable, though patients with EoE and PPI-REE were younger, presented a higher prevalence of allergic comorbidities, and complained of symptoms of dysphagia more frequently than those with RE. The only noteworthy differences between EoE and PPI-REE were more frequent reports of asthma (36.4 vs. 2.6 %) and food allergy (27.3 vs. 0 %) by patients with EoE (P eosinophilia is difficult and requires further investigation.

    Identifying pregnant women with sepsis is challenging because diagnostic clinical and laboratory criteria overlap with normal pregnant physiologic indices. Our primary study aim was to describe clinical and laboratory characteristics of women diagnosed with sepsis, severe sepsis and septic shock. Our secondary aim was to determine positive predictive values for International Classification of Disease (ICD)-9 billing codes for sepsis, severe sepsis, and septic shock. After gaining Institutional Review Board approval, we identified women with ICD-9 codes for sepsis, severe sepsis and septic shock who were admitted to a single tertiary obstetric center from 2007-2013. Diagnoses were confirmed using criteria from the International Sepsis Definitions Conference report. Demographic, obstetric, vital signs and laboratory data were abstracted by medical chart review. We identified 190 women with sepsis-related ICD-9 codes: of these, 35 (18%) women met the criteria for a clinical diagnosis of sepsis, severe sepsis or septic shock. Twenty (57%) women had a sepsis-related diagnosis after cesarean delivery. Twenty-one (60%) women had one or more pre-existing medical conditions and 19 (54%) women had one or more obstetric-related conditions. The genital tract was the most common site of infection. We observed considerable heterogeneity in maternal vital signs and laboratory indices for women with ICD-9 codes for sepsis, severe sepsis, and septic shock. The positive predictive value for each sepsis-related ICD-9 code was low: 16% (95% CI 10 to 24%) for sepsis, 10% (95% CI 3 to 25%) for severe sepsis and 24% (95% CI 10 to 46%) for septic shock. We identified marked heterogeneity in patient characteristics, clinical features, laboratory indices and microbiological findings among cohorts of women diagnosed with maternal sepsis, severe sepsis or septic shock. Based on our findings, the incidence of maternal sepsis using ICD-9 codes may be significantly overestimated. Copyright

    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.

    Objective: To describe the radiological and clinical features of adult non-puerperal mastitis and to determine the most accurate method of preventing unnecessary surgical procedures. Methods: Clinical and imaging findings were retrospectively reviewed in 51 females with non-puerperal mastitis, which was confirmed by biopsy/surgical pathology. All 51 patients had pre-operative MRI; 45 patients also had sonograms and 25 also had mammograms, pre-operatively. Results: Of the 51 cases with non-puerperal mastitis, 94.1% (48/51) were confirmed as having acute or chronic inflammation, and the other 3 had plasma cell mastitis; areola papillaris inflammation was found in 39.2% (20/51) of the cases. Overall, 6 of the 25 cases that were examined with mammography and 2 of the 45 cases that were examined with sonography appeared normal, but all 51 lesions were positively identified on MRI. Asymmetrical density (12/25) on mammograms and solitary or separated/contiguous, clustered, hypoechoic mass-like lesions (31/45) on ultrasound were the most common signs of non-puerperal mastitis. On enhanced MRI, 90.2% (46/51) of patients showed non-mass-like enhanced lesions. Multiple regional enhancements in the pattern of distribution (32/46) and separated or contiguous, clustered, rim-like enhancements in the pattern of internal enhancement (29/46) were the most common manifestations in non-mass-like enhanced lesions. Of the 51 patients, mastitis Type 1 and Type 2 in the time–signal intensity curve were detected in 47.1% and 51.0% of the patients, respectively. The breast imaging reporting and data system categories with the highest number of patients were Category 0 (9/25) on mammography, Category 4a on sonography (18/45) and Category 4a on MRI (29/51). Conclusion: The findings from mammography and ultrasound are non-specific; therefore, using MR can be helpful in the diagnosis, especially in the presence of non-mass-like enhancements that are multiple, regional, separated, or

    Full Text Available Background To investigate the gene mutation and clinical features of hypokalemic periodic paralysis (HypoPP in a Han family. Methods Mutation analyses of CACNA1S, SCN4A and KCNE3 gene were screened by DNA direct sequencing in the proband (Ⅲ3. Then, other patients and one asymptomatic relative were tested for the mutation detected in the proband before. Besides, clinical information was collected and analyzed carefully so as to detect whether the mutations were responsible for HypoPP.  Results KCNE3 gene was not detected in the propositus (Ⅲ 3. Mutations of IVS25-194C/T in CACNA1S gene were detected in the propositus (Ⅲ 3 and other patients (Ⅱ 1, Ⅲ 4, Ⅳ 3, while it was not detected in the asymptomatic relative (Ⅲ1. Given that it was an intron mutation, we presumed that it was not responsible for HypoPP in this family. In addition, mutations of IVS18-130G/A in SCN4A gene were detected in all patients (except for Ⅰ1 and asymptomatic relative (Ⅲ 1. Since it was an intron mutation and it was detected in symptomatic or asymptomatic members simultaneously, we also presumed that it was not responsible for HypoPP in this family. Interestingly, a missense mutation (V662I of c.1984G > A in exon 12 of SCN4A gene was detected in the proband (Ⅲ 3 and asymptomatic relative (Ⅲ 1. However, it was not detected in other symptomatic members ( Ⅱ 1, Ⅲ 4, Ⅳ 3. Based on clinical information and bioinformatics, we presumed that it was not causative mutation for the disease in this pedigree.  Conclusions This pedigree research enriched the data of gene mutation and clinical features of HypoPP in China. Besides for gene KCNE3, CACNA1S and SCN4A, other gene mutations accounted for HypoPP in the Han family should be further studied. doi: 10.3969/j.issn.1672-6731.2014.06.006

    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.

    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

    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

    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.

    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.

    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.

    To correlate the amount of bone marrow edema (BME) calculated by magnetic resonance imaging(MRI) with clinical findings, histopathology, and radiographic findings, in patients with advanced hip osteoarthritis(OA). The study was approved by The Institutional Human Subject Protection Committee. Coronal MRI of hips was acquired in 19 patients who underwent hip replacement. A spin echo (SE) sequence with four echoes and separate fast spin echo (FSE) proton density (PD)-weighted SE sequences of fat (F) and water (W) were acquired with water and fat suppression, respectively. T2 and water:fat ratio calculations were made for the outlined regions of interest. The calculated MRI values were correlated with the clinical, radiographic, and histopathologic findings. Analyses of variance were done on the MRI data for W/(W + F) and for T2 values (total and focal values) for the symptomatic and contralateral hips. The values were significantly higher in the study group. Statistically significant correlations were found between pain and total W/(W + F), pain and focal T2 values, and the number of microfractures and calculated BME for the focal W/(W + F) in the proximal femora. Statistically significant correlations were found between the radiographic findings and MRI values for total W/(W + F), focal W/(W + F) and focal T2 and among the radiographic findings, pain, and hip movement. On histopathology, only a small amount of BME was seen in eight proximal femora. The amount of BME in the OA hip, as measured by MRI, correlates with the severity of pain, radiographic findings, and number of microfractures. (orig.)

    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 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 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.

    Ebola virus disease is caused by a highly contagious and pathogenic threadlike RNA virus of the Filoviridae family. The index human case is usually a zoonosis that launches human-to-human transmission interface with varying levels of sustainability of the epidemic depending on the level of public health preparedness of the affected country and the Ebola virus strain. The disease affects all age groups in the population. Clinical diagnosis is challenging in index cases especially in the early stages of the disease when the presenting features are usually nonspecific and only similar to a flu-like illness. However, in the agonal stages, hemorrhage frequently occurs in a high proportion of cases. The diagnostic gold standard is by detecting the antigen using reverse transcription-polymerase chain reaction. Mortality rates in the past 28 outbreaks since 1976 have ranged from 30% to 100% in different settings among adults, but lower mortality rates have been documented in children. This review aims to describe Ebola virus infection, clinical presentation, diagnosis and outcomes in children.

    To analyze the clinical characteristics of protracted bacterial bronchitis (PBB) in children. The clinical data of patients seen from October, 2010 to March, 2014 in Department of Respiratory Diseases of our hospital were retrospectively analyzed. Inclusion criteria were over 4 weeks cough, receiving fiberoptic bronchoscopy, positive bacterial culture and (or) the increased percentage of neutral granulocytes in bronchoalveolar lavage fluid (BALF). Twenty eight patients were involved, 26 were male (93%) and two were female (7%). The median age of patients was 8.5 months. The median duration of cough was four weeks. The average length of hospital stay was (8.3 ± 3.9)days. The main clinical feature was wet cough in 28 cases, wet cough with wheezing was seen in 21 cases. The wet cough phase distribution was irregular in 21 cases. The crackles with wheeze (in 21 cases) was main signs of PBB. The percentage of CD3⁻ CD16⁺ 56⁺ cells increased in peripheral blood. The fiberoptic bronchoscopic manifestations of PBB were luminal mucosal edema. Eleven patients also had airway malacia. The neutrophil median in BALF was 0.2. The positive rate of bacterial culture of BALF was 36%. The main bacteria were Streptococcus pneumoniae (50%) and Haemophilus influenzae (30%). The main treatment for PBB patients included amoxycillin/clavulanate potassium and second-generation cephalosporins. The average duration of treatment was (17.3 ± 3.2)days, the prognosis was good. PBB is common in male infants. Persistent wet cough with wheezing was the main characteristic of PBB. PBB is commonly accompanied by immune dysfunction and airway malacia, and the pathogens were Streptococcus pneumoniae and Haemophilus influenzae.

    To analyze the clinical features and treatment of skull base osteosarcoma. The clinical data of 18 patients with skull base osteosarcoma, who were admitted to the CAMS Cancer Hospital from January 2005 to November 2013, were retrospectively analyzed. The patients were followed up by telephone, outpatient review and other means. Fifteen patients were followed up, 4 cases received surgery only, and 11 cases received surgery with adjuvant chemotherapy and/or radiotherapy. Kaplan-Meier survival curve analysis was used to analyze the clinical data and Log rank method was used for verification. Nine patients died among the 15 patients who were followed up for 3-103 months (mean 25.0 months): seven patients died of local recurrence, and two patients died of distant metastasis, and six patients were still alive. Four patients received surgery only, with a median survival time of 25.0 months, and 11 patients received comprehensive treatment, with a median survival time of 47.0 months (P = 0.02). Five patients received sub-total resection, with a mean survival time of 47.0 months, and 10 patients received total resection, with a mean survival time of 45.0 months (P = 0.37). The 1- and 2-year recurrence rates were 46.6% and 68.9%, respectively. The overall 1-, 2-, 3- and 5-year survival rates were 82.4%, 61.8%, 36.0% and 36.0%, respectively, with a median survival time of 30.0 months. To compare the long bone and head and neck osteosarcoma with skull base osteosarcoma, the skull base osteosarcoma has a lower total resection rate, a higher recurrence rate, and a poorer prognosis. Radical surgery and comprehensive treatment are appropriate for skull base osteosarcoma.

    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

    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 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.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.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 in future outbreaks

    Extracranial meningiomas of the head and neck region are rare neoplasms, the majority being a secondary location of a primary intracranial tumour. We herewith report three rare cases of extracranial meningiomas, located in the temporal muscle, parotid gland and nasal cavity, together with complete pathological, immunohistochemical and ultrastructural studies. Prognosis of this tumour is generally excellent. Surgical excision is the treatment of choice, with no need for further treatment; nevertheless, differential diagnosis must consider other more common tumours of the head and neck and be based on histopathologic examination and relative techniques, including examination of frozen sections. This procedure is particularly useful assessing surgical treatment and should be performed whenever possible to exclude the malignant nature of the lesion and avoid over-treatment. All three patients underwent surgery and are alive and disease-free.

    Full Text Available Introduction: Identifying clinical features that differentiate acute febrile thrombocytopaenia from acute febrile illness without thrombocytopaenia can help primary care physician to decide whether to order a full blood count (FBC. This is important because thrombocytopaenia in viral fever may signify more serious underlying aetiology like dengue infection.Objective: The aim of this study was to compare the clinical features of acute febrile patients with thrombocytopaenia and acute febrile patients without thrombocytopaenia.Methodology: This was a clinic-based cross-sectional study from May to November 2003. Consecutive patients presenting with undifferentiated fever of less than two weeks were selected from the Primary Care Centre of Hospital Universiti Kebangsaan Malaysia and Batu 9 Cheras Health Clinic. Clinical features of these patients were recorded and FBC examination was done for all patients. Thrombocytopaenia was defined as platelet count <150X109/L. The odds ratio of thrombocytopaenia for each presenting symptoms was calculated.Result: Seventy-three patients participated in this study. Among them, 45.2% had thrombocytopaenia. Myalgia and headache were common among all patients. However, nausea and vomiting occurred significantly more often among patients with thrombocytopaenia than in patients with normal platelet count (OR 2.2, 95% CI 1.1-4.5.Conclusion: Acute non-specific febrile patients presenting with symptoms of nausea and vomiting may have higher risk of thrombocytopaenia and should be seriously considered for FBC.

    OBJECTIVE: To thoroughly investigate clinical characteristics of progressive supranuclear palsy (PSP) in a Chinese population.METHODS: Computer-based online searches through China National Knowledge Infrastructure and Weipu Periodical Database were performed to collect case reports of PSP published between 1980 and 2009. Clinical characteristics were analyzed.RESULTS: A total of 58 studies comprising 105 patients (76 males and 29 females) were included. All cases were sporadic and free of family history. The mean age at onset was 60.6 ± 9.1 years, and the mean course from onset of symptoms to diagnosis was 3.4 ± 2.4 years. The male-to-female ratio was approximately 3: 1. Onset was characterized by akinetic-rigid features and accounted for 34.3% of all cases, followed by early postural instability (25.5%), pseudobulbar palsy (9.8%), cognitive impairment (9.8%), and vertical supranuclear ophthalmoplegia (7.8%). With disease progression, vertical supranuclear ophthalmoplegia was reported in 95.1% of cases, followed by akinetic-rigid features (83.3%), pseudobulbar palsy (82.4%), axial dystonia (75.5%), cognitive impairment (72.5%), and early postural instability (69.6%). A total of 70.5% of patients exhibited abnormal electroencephalograms, and 21.4% exhibited mild abnormalities in cerebrospinal fluid. Brain CT scanning results of 37 patients showed 37.8% with midbrain and concurrent cerebral hemisphere atrophy, and 5.4% and 24.3% with midbrain and cerebral hemisphere atrophy, respectively. Brain MRI scanning results of 55 patients revealed a total of 16.4% patients with midbrain atrophy, 23.6% with midbrain and concurrent cerebral hemisphere atrophy, 32.7% with cerebral hemisphere atrophy, and 11% with brainstem atrophy. The percentage of midbrain atrophy revealed by MRI was greater than by CT. All 11 patients subjected to Mini-Mental State Examination scored < 23. A total of 10 patients underwent brain electrophysiological examination, and 80% presented with

    Delusional jealousy is a psychotic syndrome characterized by a belief in the infidelity of one's spouse that reaches delusional intensity. Although delusional jealousy has been described in relation to organic psychosis, little is known concerning the actual role of delusional jealousy in dementia. The aim of the present study was to investigate the clinical features of delusional jealousy and possible mechanisms whereby delusional jealousy arises in patients with dementia. We studied 208 consecutive outpatients with dementia (diagnosis based on DSM-III-R criteria; mean [SD] age of 77.0 [8.0] years; study period: September 2011-August 2012). Delusional jealousy was defined as a false belief derived from a pathological jealousy that makes the patient believe that his or her spouse is unfaithful. The prevalence of delusional jealousy was compared between Alzheimer's disease, dementia with Lewy bodies, and vascular dementia. Patients with and without delusional jealousy were compared in terms of general characteristics. In addition, each patient with delusional jealousy and their primary caregivers were interviewed about the clinical features of the syndrome. Of the 208 patients with dementia, 18 (8.7%) showed delusional jealousy. The prevalence of delusional jealousy in patients who had dementia with Lewy bodies (26.3%) was significantly higher than that in patients with Alzheimer's disease (5.5%) (P delusional jealousy in regard to gender (P = 1.00), age (P = .81), educational attainment (P = .29), presence of other persons living with the couple (P = .22), and Mini-Mental State Examination score (P = .47). On the other hand, delusional jealousy was preceded by the onset of serious physical diseases in nearly half of the patients. Delusional jealousy resolved within 12 months after treatment in 15 of 18 patients (83%). Although delusional jealousy is a considerable problem in dementia, the prognosis of delusional jealousy in demented patients appears to be

     Objectives: To characterize the clinical presentations and diagnosis including serological tests and histopathological findings in children with celiac disease. Methods: All children (less than 18 years) with confirmed celiac disease diagnosed over a 6 year period at a private tertiary care health care center in Riyadh,  Saudi Arabia were studied retrospectively. Information collected included demographics, clinical presentation and diagnostic modalities with serology and small intestinal histology reported by Marsh grading. Results: A total of 59 children had confirmed celiac disease. Thirty (50.8%) were male. Median age was 8 years (range 1 to 16 years). The mean duration of symptoms before diagnosis was 2.3 (±1.5) years. Classical disease was present only in 30.5%, whereas 69.5% had either non-classical presentations or belonged to high risk groups for celiac disease such as those with type-1 diabetes, autoimmune thyroiditis, Down syndrome and siblings. Failure to thrive was the most common presentation followed by short stature, abdominal pain and chronic diarrhea. Anti-tissue transglutaminase antibody was positive in 91.5%, and titers were no different between those with classical and non-classical disease. All had Marsh-graded biopsy findings consistent with celiac disease. Conclusion: Children with celiac disease usually present with non-classical features. A high index of suspicion needs to be maintained to consider this disorder in the diagnostic workup of pediatric patients. High risk group should be screened early to avoid complications associated with untreated celiac disease.

    To correlate Multi-spectral Digital Skin Lesion Analysis classifier scores with histopathological severity of pigmented lesions and clinical features of melanoma. Classifier scores were computed for 1,632 skin lesions. Dermatologists evaluated the same lesions for Asymmetry, Border Irregularity, Color variegation, Diameter >6mm, Evolution, Patient's Concern, Regression, and/or "Ugly Duckling" sign. Classifier scores were correlated to the number of clinical risk features and for six histopathological severity levels of pigmented lesions. Average classifier score, Welch's t-test, and chi-square analysis. Melanomas had higher mean classifier scores (3.5) than high-grade dysplastic nevi (2.7, p=0.002), low-grade dysplastic nevi (1.7, pClassifier score and the number of clinical risk characteristics directly correlated (Pearson coefficient 0.32, pclassifier scores to clinical and histological melanoma features supports the effectiveness of Multi-spectral Digital Skin Lesion Analysis in assessing the risk of pigmented lesions requiring biopsy. Optimizing outcomes of dermatologist decisions to biopsy suspicious pigmented lesions may be enhanced utilizing Multi-spectral Digital Skin Lesion Analysis.

    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.

    To describe the clinical characteristics and surgical outcomes of a group of patients with age-related distance esotropia (ARDE). A retrospective study was conducted on a consecutive case series of 16 adult patients diagnosed with ARDE between 2008 and 2015. The clinical features evaluated included mean age and gender, primary position deviations at distance and near, measured in prism dioptres (pd), treatment offered in each case, and post-surgical deviations. Ductions and versions were full, with no evidence of lateral rectus paresis. None of these patients had any obvious underlying neurological disorder, such as, high myopia or thyroid disease. A good result is considered to be the disappearance of diplopia in all positions of gaze. A total of 16 patients (11 females [68.8%]) were identified. The mean age at diagnosis was 78.19±6.77 years. The mean initial esodeviation was 2.25±3.08 pd at near (-4 to +8 pd) and 9.5±4.18 pd at distance (2 to 18 pd). Treatment was not necessary in 5 cases because the symptoms were intermittent or well-tolerated. Of the 11 patients with symptoms, one was corrected with an external base therapeutic prism. Botulinum toxin was administered in another patient, without satisfactory results. Unilateral medial rectus muscle recession was performed on one patient, and unilateral lateral rectus plication on 7 patients, indicating prisms before surgery. One patient refused surgery despite continuous diplopia in far vision. After a mean follow-up of 16.5 months, all operated patients were asymptomatic. Not all patients with ARDE require treatment, as the tolerance to diplopia varies from one subject to another. Both medial rectus weakening and lateral rectus strengthening provides excellent results. Crown Copyright © 2016. Publicado por Elsevier España, S.L.U. All rights reserved.

    Obesity occurs in both clinical and animal forms in a variety of specific models which allow study of its underlining endocrine and mechanistic features. Among the neuroendocrine varieties of obesity, polycystic ovaries are probably the most common. The importance of the gonadal feedback system for regulation of food intake and obesity is indicated by the effects of castration in experimental animals which is a widely used mechanism for producing experimental obesity. Cushing syndrome and hypothalamic obesity are rare clinical syndromes. The current evidence suggests that there are two types of hypothalamic obesity from a mechanistic point of view--one associated with hyperphagia as a necessary and sufficient cause and a disturbance of the autonomic nervous system without hyperphagia as a second mechanism. Although genetic factors underlie most types of human obesity, there are several dymorphic forms of obesity including the Prader-Willy syndrome, Cohen's syndrome, Carpenter's syndrome, Ahlstrom's syndrome and the Bardet-Biedel syndrome. The Prader-Willi syndrome is characterized by obesity hypotonia hypogonadism and mental retardation. In animals, a dominant form of inheritance of obesity is seen in the yellow mouse. Current evidence suggests that this syndrome can be explained by reduced acetylation of MSH in the pituitary and/or hypothalamus. Several recessively inherited forms of obesity exist including the obese mouse, the diabetes mouse, fatty rat, the fat mouse, tubby mouse and the corpulent rat. In addition, there are a number of polygenic types of experimental obesity. The final mechanistic classification of obesity are those due to dietary manipulation. For both human beings and animals, a highly fat diet appears to be particularly problematic for the development of obesity.(ABSTRACT TRUNCATED AT 250 WORDS)
