A cross-sectional clinico-radiologic evaluation of occipito-atlantoaxial (OC1C2) region of 2 population groups. Determine the prevalence of OC1C2 osteoarthritis in porters involved in carrying loads on the head and general male population. Describe its clinico-radiologic manifestations. In addition to age, head loading is a known cause of degeneration affecting the occipito-cervical region. The impact of head loading in the population aged between third and sixth decade is unknown. Head loading is a common custom in the developing countries. Study group (n = 107) included randomly selected male porters from railway stations who underwent computed tomography (CT) study of the OC1C2 region, plain radiographs of the cervical spine and detailed clinical examination. Control group (n = 107) included randomly selected male patients undergoing CT scan study for diseases of paranasal sinuses with coincidental screening of OC1C2 region along with clinical assessment. The data were analyzed using SPSS 15 software. Mean age for study group was 32.6 years and controls was 34.6 years (P = 0.156). In the study group, duration of occupational exposure was 10.9 (+/-8.7) years; 81.3% porters being symptomatic with an age of 33.4 (+/-9.6) years. Radiologic prevalence of OC1C2 osteoarthritis in study group was 91.6% and in control group was 6.8%; age of affected individuals was 33.4 (+/-9.3) and 47.9 (+/-8.0) years, respectively. Most common complaint was suboccipital neck pain (69.7%); while the CT finding was decreased joint space with sclerosis and irregularity of the margins (81.3%). No statistically significant association was found between presence of radiologic changes and symptoms. Age, duration of occupational exposure and its relationship with various clinico-radiologic manifestations was studied. This condition has significant prevalence in porters, beginning at an early age. Diagnosis is based on the clinico-radiologic presentation. CT is the investigation of choice

Full Text Available OBJETIVO: o ultrassom (US tem sido uma importante ferramenta de diagnóstico para identificar várias causas de hemorragia gastrointestinal. Neonatos com alergia ao leite de vaca (ALV podem apresentar hematoquezia, e a confirmação do diagnóstico pode ser difícil. O objetivo deste estudo é descrever achados com ultrassom em escala de cinza e com Doppler colorido em pacientes com ALV. MÉTODOS: estudamos, retrospectivamente, 13 neonatos com ALV. Todos eles apresentaram hematoquezia severa e dor abdominal e foram submetidos a um estudo com US, com o diagnóstico de colite alérgica. O diagnóstico teve como base os achados clínicos, a recuperação após a dieta de exclusão do neonato ou da mãe, no caso de amamentação exclusiva, e o teste de provocação oral positivo. RESULTADOS: a idade média variou de um a seis meses (média = 3,53. Sete dos 13 neonatos (53,8% passaram novamente por ultrassonografia em escala de cinza e com Doppler colorido após a dieta de exclusão. Dentre eles, 12 dos 13 (92,3% mostraram anormalidades no US e no ultrassom com Doppler colorido (USDC no início. Os achados positivos que sugeriram colite foram paredes intestinais espessas e aumento na vascularização, principalmente no cólon descendente e sigmoide. Os resultados da colonoscopia e histopatológicos foram compatíveis com colite alérgica. Após uma mudança na dieta, os 13 neonatos se recuperaram e seus testes de provocação oral foram positivos. CONCLUSÃO: o US com Doppler pode ser muito útil para diagnosticar a colite secundária, como a ALV, e para excluir várias outras doenças abdominais que podem imitar essa doença.

Clinico-anatomic observation of autosomal-recessive renal cystic disease and congenital hepatic fibrosis at two fetuses from the same family was done. Mutation of His3124Tyr in 58 exon of PKHD1 gene in heterozygous state was found out. The same pathomorphological changes in the epithelium of cystic renal tubules and bile ducts of the liver were noted. We suggest that the autopsy research of fetuses with congenital abnormalities, detected after prenatal ultrasonic screening, has high diagnostic importance.

To determine the clinico haematological features, treatment and outcome of children diagnosed with aplastic anemia at a single institution. Study Design: Observational study. Place and Duration of Study: The Aga Khan University Hospital, Karachi, from January 1999 till December 2008. Methodology: Medical records of children aged less than 15 years of age diagnosed with aplastic anemia were reviewed. Clinico haematological features, treatment and its response to therapy and outcome were recorded. Results were described in percentages. Results: Ninety patients were diagnosed to have aplastic anemia (AA); 65 were male during the study period. Age ranged from 1 to 15 years. Fever in 65 patients (72.2%), pallor in 53 (58.8%), skin bleeding in 49 (54.4%) and epistaxis in 31(34.4%) were the most common and frequent presenting features. Congenital (Fanconi's) anemia was found in 15 (16.6%) and acquired idiopathic in 75 (83.4%) of patients. Very severe aplastic anemia (VSAA) was seen in 29 (32.2%), 26 (28.9%) had severe AA and 17 (18.9%) had moderate AA. Eight patients (8.9%) underwent haematopoietic stem cell transplantation (HSCT), 12 (13.3%) received immunosuppressive therapy (IST) and 70 patients (77.7%) received other and supportive therapy. Five (62.5%) patients showed complete response to HSCT and 3 (37.5%) failed to engraft. IST showed complete response in 3 (25%), partial response in 5 (41.6%) and no response in 4 (33.3%). Twenty two patients (24.4%) expired either due to infection in 16 (72.7%, fungal in 6, bacterial in 10) and intracranial haemorrhage in 6 (27.3%) cases. Conclusion: Majority of cases with AA were acquired and idiopathic in etiology. VSAA and SAA were frequent. Response to HSCT and IST was sub-optimal. (author)

Lichen planus and lichenoid lesions affecting the oral cavity show similar clinico-pathological features creating a diagnostic dilemma. Hence, the aim of the present study was to establish a clinical and histopathological correlation in the diagnosis of oral lichen planus, based on the modified WHO diagnostic criteria of oral lichen planus and oral lichenoid lesions proposed by Van der Meij and Van der Waal in 2003. In the present study, 100 cases of oral lichen planus were clinically and histopathologically analyzed. Out of the 100 cases, 50 were prospective and 50 were retrospective cases. Prospective cases were collected based on the clinical diagnosis of oral lichen planus and oral lichenoid lesion. Retrospective cases were collected based on the histopathological diagnosis of oral lichen planus. Both the clinical and histopathological analyses were performed based on a proposal for a set of modified diagnostic criteria of oral lichen planus and oral lichenoid lesion. A final diagnosis of oral lichen planus was made only after the correlation of the clinical diagnosis with the histopathological diagnosis. The interobserver agreement among three observers for both prospective and retrospective cases in the final diagnosis of oral lichen planus was found to be "good" to "very good" indicating high reproducibility. However, the final diagnoses of true oral lichen planus after clinico-pathological correlation in prospective and retrospective study groups appeared to be 38.0% and 54.0% respectively. The results of the present study revealed mild to moderate clinico-pathological correlation in the final diagnosis of oral lichen planus for the prospective and retrospective study groups respectively.

Pulmonary infections by Sporothrix spp. manifest radiologically as cavitary or non-cavitary disease depending on whether the infection is primary pulmonary or multifocal sporotrichosis. Despite current guidelines, the optimal management for pulmonary sporotrichosis remains unclear. In order to clarify this, we present two cases of pulmonary sporotrichosis, as well as the results of a comprehensive literature review of treatment outcomes based on clinico-radiological presentation patterns of the disease. A literature search of all case reports in English language over the last 50 years (1960-2010) was conducted. Data on patient characteristics, risk factors, clinico-radiological patterns, treatment modalities and outcomes were collected and analyzed. A total of 86 cases were identified, i.e., 64 (74.4%) primary pulmonary and 22 (25.6%) multifocal sporotrichosis. Radiologically, primary pulmonary disease was commonly characterized by cavity formation which was lacking in multifocal infections (P = 0.0001). Immunosuppressant use was more common in multifocal sporotrichosis (P = 0.0001), while hemoptysis was more common in primary pulmonary form (P = 0.01). No other differences in patient characteristics or risk factors were noted. Extra-pulmonary multifocal sporotrichosis most commonly involved skin (81.8%) and joints (45.4%). For patients with cavitary primary pulmonary sporotrichosis, outcomes from medical therapy alone were inferior to surgical intervention (P = 0.02). However, for both primary pulmonary and multifocal sporotrichosis with non-cavitary disease, medical therapy alone provided good outcomes. Only 12 (16.7%) cases were treated with itraconazole. Treatment of pulmonary sporotrichosis should be guided by the clinico-radiological patterns of presentation. Medical therapy alone is likely sufficient for non-cavitary disease while early surgery should be considered for cavitary primary pulmonary sporotrichosis.

Definite clinico-cytological criterion is outlined for thyroid lesions. Fine needle aspiration cytology (FNAC) makes it easier to segregate cases of thyroiditis (Chronic lymphocytic thyroiditis/Hashimoto's thyroiditis-CLT/HT, and subacute thyroiditis-SAT) from other benign and malignant lesions of thyroid. The study was done for a period of 5½ years at a diagnostic centre in Guwahati. Patients underwent FNAC and smears were studied for cytomorphology. A correlation with clinical features and thyroid function, including antithyroid antibody estimation, was done, wherever possible. 792 thyroid lesions were encountered during the study, of which 213 (26.89 %) were cases of thyroiditis (70.43 % CLT/HT, 24.9 % SAT and 3.76 % having overlapping features of CLT/HT and SAT); 2 cases (0.9 %) of CLT showed suspicion of Non-Hodgkin's Lymphoma (NHL), which was confirmed on histopathology. 24 cases (11.26 %) belonged to different ethnic tribal groups of Northeast India. CLT/HT presented predominantly with diffuse thyroid enlargement, but 12 cases (8 % of CLT/HT cases) had nodular enlargement. Patients presented with predominantly hypothyroidism; however occasional hyperthyroid cases were also seen. SAT showed signs of inflammation and presented with hyperthyroidism. Overlap cases of CLT/HT and SAT showed combined clinico-cytomorphological features of both lesions. 37.5 % cases with overlapping features belonged to tribal communities. A rise in incidence of thyroiditis, particularly CLT/HT, was seen. Overlap features of CLT/HT and SAT was noticed in significant percentage. No bias was noticed amongst any specific tribal community. FNAC, coupled with clinico-serological study, helps to diagnose thyroiditis at early stage.

Incidental parotid lesions on F-18 FDG-PET can mimic distant metastasis of underlying malignancy. The prevalence and the clinico-pathologic findings of PET positive parotid lesions have not been known. We investigated how often incidental parotid lesions are found on clinical FDG-PET studies and what the clinico-pathologic characteristics of those parotid lesions are in the present study. We retrospectively reviewed 3,344 cases of FDG-PET which had been obtained in our hospital from May 2003 to Dec 2006. The indications of FDG-PET were: evaluation of known/suspected cancer (n = 3,212) or screening of cancer in healthy subjects (n = 132). Incidental parotid lesion on FDG-PET was defined as an un-expected FDG uptake in one of parotid glands which was not primary target lesion of current FDG/PET. FDG uptake was represented by maximum standardized uptake value (maxSUV). Final diagnosis was made by pathologic analysis or clinical follow-up assessment. Fifteen (0.45% = 15/3,344) incidental parotid lesions were found and they were all benign lesions. The maxSUV ranged from 1.7 to 8.6 (mean ± s.d. = 3.7 ± 1.9). Final diagnoses of the incidental parotid lesions were; Warthin's tumor (n = 2), pleomorphic adenoma (n = 1), other un-specified benign lesion (n 1), and benign lesions under bases of imaging studies (n = 3) and of clinical follow-up (n = 8). All of incidentally found parotid lesions in clinical FDG-PET studies were confirmed as benign lesions with prevalence of 0.45%. Close follow up using PET or CT might be a reasonable approach for determining the nature of incidentally found parotid lesions

Herpes zoster is a common viral infection of skin caused by reactivation of varicella zoster virus infection from the spinal ganglia. The clinico-epidemiological patterns of this disease in an Indian setting required to be studied. A cross sectional study was conducted on all consecutive cases of herpes zoster reporting to the Dermatology Outpatient Department at a Tertiary Care Hospital in Bangalore during a period of one year from 01 Jun 2013 to 31 May 2014. Detailed history, examination, HIV screening and Tzanck smear were carried out in all cases. 84 cases of herpes zoster were seen with a mean age of 30 years. Majority (39%) of cases were seen in the 21-30 year age group. Thoracic segments were involved in 65.4%, cervical in 11.9%, cranial in 11.5%, lumbar in 8.3% and sacral segments in 3.5%. 63% of cases had zoster associated pain. One case had motor involvement.3.57% of the patients were HIV positive. This study shows a lower age incidence of herpes zoster HIV positivity and zoster associated pain as compared to other studies. The pattern of segmental involvement in herpes zoster seen in this study was similar to other studies.

Clinico-pathological findings of CSF dissemination which was diagnosed on CT scan, were studied on 13 cases of glioblastoma and 9 cases of medulloblastoma. The type of CSF dissemination and the prognosis of patients were both different between glioblastoma and medulloblastoma. In the former, the dissemination was predominantly in ventricular walls and in the latter, in basal cisterns. The mean survival time after the diagnosis of dissemination is 6 months of glioblastoma as compared with 13 months of medulloblastoma. The Pathological studies show that subependymal and/or subpial infiltration of tumor cells, and thickness of arachnoid membrane by marked mesodermal reaction were demonstrated in cases of glioblastoma. On the contrary, tumor cells of medulloblastoma grow markedly in the subarachnoid space and/or on the ependymal layers. From these pathological findings of CSF dissemination, it will be resulted that the prognosis of glioblastoma is much more poor that of medulloblastoma. (author)

The clinico-pathological features were recorded. miRNA profiling was performed in formalin fixed paraffin embedded (FFPE UM samples (n = 6 using Agilent, Human miRNA microarray, 8x15KV3 arrays. The association between miRNAs and clinico-pathological features were studied using univariate and multivariate analysis. miRNA-gene targets were predicted using Target-scan and MiRanda database. Significantly dys-regulated miRNAs were validated in FFPE UM (n = 86 and mRNAs were validated in frozen UM (n = 10 by qRT-PCR. Metastasis free-survival and miRNA expressions were analysed by Kaplen-Meier analysis in UM tissues (n = 52.Unsupervised analysis revealed 585 differentially expressed miRNAs while supervised analysis demonstrated 82 miRNAs (FDR; Q = 0.0. Differential expression of 8 miRNAs: miR-214, miR-149*, miR-143, miR-146b, miR-199a, let7b, miR-1238 and miR-134 were studied. Gene target prediction revealed SMAD4, WISP1, HIPK1, HDAC8 and C-KIT as the post-transcriptional regulators of miR-146b, miR-199a, miR-1238 and miR-134. Five miRNAs (miR-214, miR146b, miR-143, miR-199a and miR-134 were found to be differentially expressed in M3/ D3 UM tumors. In UM patients with liver metastasis, miR-149* and miR-134 expressions were strongly correlated.UM can be stratified using miRNAs from FFPE sections. miRNAs predicting liver metastasis and survival have been identified. Mechanistic linkage of de-regulated miRNA/mRNA expressions provide new insights on their role in UM progression and aggressiveness.

Full Text Available Background: The purpose of the study was to correlate the provisional diagnosis of pericoronal radiolucencies associated with impacted, embedded, or unerupted teeth with the histopathologic diagnosis, and also to emphasize the importance of early detection for better diagnosis and management. Methods: This is a retrospective study involving 18 cases of pericoronal radiolucencies associated with unerupted, embedded, or impacted teeth whose data during 1-year period were retrieved, and were reviewed for clinical, radiological, and histopathologic data. Also, comparison and correlation of clinico-histopathologic diagnosis was made. Results: Of the 18 cases, 11 were provisionally diagnosed as dentigerous cyst and the remaining were diagnosed as ameloblastoma, odontogenic keratocyst, adenomatoid odontogenic tumor, and calcifying epithelial odontogenic cyst. Histopathologic diagnosis of the 18 cases showed varied results, with only 10% correlating with the provisional diagnosis. Conclusion: Although many pathological processes may present radiographically as pericoronal radiolucencies associated with unerupted teeth, the most common is the dentigerous cyst. Hence, it is crucial for the clinician to fully investigate all teeth that fail to erupt at the expected time, and promptly initiate appropriate assessment and management of suspected cystic lesions.

Granular cell tumor (GCT) is uncommonly presented with cutaneous ulcer. We examined the clinico pathological and immunohistochemical features of this ulcerative form in fourteen cases that may raise the awareness of this variant. The study included 11 males and 3 females with a mean age 31.5± 7.42 years. All cases were presented with large solitary ulcer with indurated base, elevated border, skin colored margin, and necrotic floor. Twelve lesions were located on the extremities and two lesions on the genital region. Histologically, the lesions showed dermal infiltrate composed of large polygonal cells with granular cytoplasm and characteristic infiltration of the dermal muscles in all cases. Immunostaining showed positive reaction for S100 (14/14), NSE (14/14), CD68 (5/14), and Vimentin (7/14) while HMB45, CK, EMA, and Desmin were negative. We hope that this paper increases the awareness of ulcerative GCT and consider it in the differential diagnosis of ulcerative lesions

Since the fibro-osseous lesion is not a specific diagnostic term, the author studied clinically and radiologically 44 cases which had been diagnosed as fibro-osseous lesion in SNUDH (1972-1981.12). The obtained results were as follows. 1. Clinico-radiologically, the cases of fibro-osseous lesions were divided into two groups. 2. The first group was fibrous dysplasia(21 cases). 3. The second group was tumors of periodontal ligament origin, including ossifying fibroma, cementifying fibroma and cemento-ossifying fibroma (23 cases). 4. In most cases the chief complaint was painless swelling of the jaw and the mean age of the fibrous dysplasia (24.6 yrs) was a little younger than that of the periodontal ligament origin lesions (29.2 yrs). 5.

Infectious Granulomatous Dermatoses (IGDS) have various aetiological factors with a considerable overlap in the histopathological and clinical features, thus posing a diagnostic dilemma for dermatologists and pathologists. We aimed at determining the histopathological profile of IGDS correlating it with clinical features with an attempt to find the aetiology. In a cross-sectional study conducted in a tertiary referral center of Mumbai over two years, out of 1872 skin biopsies received, 239 histopathologically diagnosed cases of IGDS were studied for histopathological features of granuloma. A clinico-histopathological correlation was attempted. Chi-square test was used for comparison of proportions of different groups. Leprosy (211 cases) and tuberculosis (28 cases) were the commonest histopathologically diagnosed IGDS. Leprosy spectrum included BT (30.33% cases), followed by TT (21.32%), BL and LL and 21.79% cases of lepra reactions. Skin TB biopsies on histopathology showed lupus vulgaris (53.85% cases), scrofuloderma (15.38%), TBVC and papulonecrotic tuberculid (11.54% each). In leprosy maximum clinico-pathological agreement was seen at tuberculoid pole (TT 72.7% and BT 56.6%). Among tuberculosis cases, scrofuloderma (100%) and lupus vulgaris (53.8%) showed maximum agreement. Leprosy and skin TB are the commonest IGDS in Mumbai region though difficult to diagnose and subcategorize with certainty during initial stages. Histopathology plays the important role to elucidate the dilemma. This being a single center study, more such studies with a larger sample size are recommended to get more elaborate data and regional prevalence of these IGDS for a better overall approach to prevention, treatment and control.

The hypothesis was that when a hospital-wide Picture Archive and Communications System (PACS) is used, preparation for clinico-radiological meetings is faster, and more images are available, than when a conventional film system is used. This paper reports a study which compared the preparation time by radiologists when film was used with the time for the same activity when a hospital-wide PACS was used at Hammersmith Hospital for the preparation of the respiratory medicine and hepato-biliary meetings. It was found that when PACS was used the time per patient to prepare for the respiratory medicine session was reduced by 11.1 min and that similarly, 16 min per patient was saved in the preparation of the hepato-biliary sessions. The number of images which were unavailable for the session was reduced when PACS was in operation, but this reduction was not shown to be statistically significant. The introduction of PACS at Hammersmith Hospital has significantly reduced the time spent by radiologists in preparing for the two clinico-radiological sessions studied and, if this is extended to the other numerous sessions held each week, contributes to a considerable saving of staff time within the radiology department.

With changing indications for performing medical liver biopsies, we aimed to develop a tool to allow pathologists to evaluate the current usefulness, value and impact of their medical liver biopsy service. We designed and piloted a questionnaire-based clinico-pathological audit for medical liver biopsies. The audit tool was simple to implement and provided useful information about our service. Hepatologists felt that 96% of reports were clinically useful. 56% of biopsies confirmed clinical diagnoses, 46% helped differentiate between diagnoses and 42% were able to exclude possible diagnoses. 74% resulted in a change of management and 27% of liver biopsies resulted in a diagnosis which was not clinically suspected. We demonstrate the usefulness of an audit tool in providing evidence of the value of the liver pathology service in a large UK regional centre. Published by the BMJ Publishing Group Limited.

To describe the clinico-pathological and radiological profile of hepatocellular carcinoma. All consecutive patients suspected of having hepatocellular carcinoma (HCC), were admitted and included in this study. Diagnosis of HCC was established by clinical, biochemical, ultrasonographic and histopathologic findings. Patients with primary carcinoma elsewhere in the body, metastatic in the liver, fibrolamellar carcinoma and benign tumours were excluded from the study. At ultrasonography, the details of tumour size and number, portal vein thrombosis and presence of ascites were recorded. Patients were staged according to Okuda staging system. Results were described in mean and percentage values. There were 82 patients with hepatocellular carcinoma including 58 males and 24 females, with male to female ratio of 2.8:1. The mean age of patients was 56.24 +- 13.65 years. Right hypochondrial pain was the main symptom in 52 (63.4%) patients. The duration of symptoms varied from 1 month to 2 years. Tumour size was larger than 50% of liver size in 42 (51.2%) with portal vein thrombosis in 10 (12.19%). Anti HCV was positive in 44 (53.7%), HBsAg in 26 (31.7%) and both were found positive in 2 (2.44%) patients. Ten patients (12.2/%) found negative both for anti-HCV and HBsAg. According to Okuda staging system 18 patients had stage 1, 50 had stage 2 and 14 had stage 3 hepatocellular carcinoma. The mean age of presentation of hepatocellular carcinoma was younger as compared to western countries with potentially large non-resectable lesions. Chronic hepatitis C and B was found to be the major known factors. Patients with chronic hepatitis C and B should undergo vigorous HCC surveillance to detect early, potentially respectable HCC.

Full Text Available OBJECTIVES To know the incidence and aetiological factors of cervical lymphadenopathy. To know the most common group of lymph nodes enlarged. To assess the response to management. MATERIALS AND METHODS This study includes 50 patients who attended the Surgical OPD, studied taking detailed clinical history, after physical examination and arriving at clinical diagnosis, confirmation was done by FNAC and biopsy. RESULTS Tuberculous lymphadenopathy is the commonest cause of cervical lymphadenopathy with 68% followed by chronic nonspecific lymphadenopathy with 32%. There was no case of sarcoidosis in this series. Disease commonly affected the 2 nd and 3 rd decades with 19% and 18% respectively. There is comparatively an increased incidence of tuberculous cervical lymphadenopathy in females than males. The average age of presentation was 30.5 years. There was no definite history of contact with tuberculosis in 82% of cases. In this study series, 44% of the patients belonged to the low income group, 46% belonged to the middle income group. There was only unilateral involvement of node in 72% of cases right side was affected in 32% and left side was affected in 40% of cases. Bilateral involvement was seen in 14% of the cases. The lymph nodes were associated with other groups of lymph nodes in 10% of cases. Chest radiography findings showed the evidence of coexisting active tuberculosis lesions in 8 out of 50 cases (16% and normal was 42(84%. CONCLUSION Knowledge about clinico-demographic perspectives of cervical lymphadenopathy in respect to their cytopathological diagnosis will help to detect/refer the respective cases early for investigations and treatment. Surgical intervention is definitely required in many cases, though most of the cases are medically curable.

Full Text Available OBJECTIVE: To describe the MRI findings of two pediatric patients with sudden sensorineural hearing loss (SSHL. CASE REPORTS: Two male patients (two-year and three-months-old, and one year and four-months-old presented with sudden dumbness. Physical and neurological examinations were unremarkable besides bilateral hypoacusia. All the laboratory investigation was negative, and brain stem auditory evoked potentials showed deep bilateral deafness in both cases. MRI studies revealed normal inner ears and multifocal white matter areas of slight low signal on T1-weighted images and high signal on FLAIR images. The follow-up MRI studies and neurological examinations did not demonstrate alterations in the previous findings. CONCLUSION: Pediatric patients with SSHL may present cerebral white matter signal abnormalities at the MRI as the only finding. Further studies with larger casuistics need to be conducted to elucidate these findings.OBJETIVO: Descrever os achados de ressonância magnética (RM em dois pacientes pediátricos com perda auditiva neuro-sensorial súbita (PANS.

Full Text Available É relatado o caso de um paciente de 14 anos, do sexo masculino, com esclerose cerebral difusa precedida em 7 anos de sinais de insuficiência do córtex supra-renal, com antecedentes familiares. Clinicamente a doença é caracterizada por deterioração mental, distúrbios da marcha e da visão, associados com insuficiência do córtex supra-renal. Confirmando os dados da literatura, em nosso caso o estudo anátomo-patológico revelou desmielinização e gliose difusa na substância branca cerebral, poupando as fibras subcorticais. Células inflamatórias são comuns e têm distribuição perivascular. Na zona fasciculada e reticular da supra-renal, células "balonadas" são evidentes, muitas delas apresentando citoplasma vacuolizado e com estriações. Inclusões lipídicas similares têm sido encontradas nas células de Schwann dos nervos periféricos e dos testículos. Os achados são comparados com vinte casos da literatura.

Full Text Available Neurocisticercose é a mais frequente e disseminada neuroparasitose humana. O desenvolvimento de lesões no cérebro e leptomeninges, com consequente aparecimento de sintomas, está relacionado com a resposta imune do hospedeiro, ao número e à fase de involução dos parasitas . Relatamos os achados anatomopatológicos durante a necrópsia em 27 casos de neurocisticercose, que corresponderam a 3,1% dos casos necropsiados no serviço. 77% dos pacientes eram masculinos, com idade variando entre 18 e 85 anos. Em 26% dos casos havia história de alcoolismo. A análise clinico-patológica mostrou que 50% dos casos eram da forma assintomática, 11% da forma epiléptica, 11% da forma intraventricular e 11% da forma combinada. 33% dos pacientes apresentaram crise epiléptica como fator agravante do quadro clínico. O cisticerco era único em 60% dos casos, a forma cellulosae estava presente em 82% e a racemosa em 7% dos casos, sendo os 11% restantes portadores da forma combinada. Em 30% dos pacientes a causa mortis estava relacionada com a presença do cisticerco no sistema nervoso central. Nossos achados confirmam a alta morbidade desta parasitose.

2008-01-01

The paper deals with a comparison of clinico-morphological patterns of sporadic thyroid cancer and that in pediatric patients exposed to radiation during the Chernobyl disaster. The latter are highly prone to both local and regional metastatic spread to the lymph nodes (intrathyroid distribution--61%; extension through capsule--42%, and metastases to the neck lymph nodes--66%). However, these data do not differ significantly from those for intact areas. Yet, cancer occurs in exposed cohorts at an earlier stage: its incidence at age 4-6 is 2-3.5 higher and that of relapse such as presentation of latent metastases to the lymph nodes and tumor foci development in residual tumor tissue is 1.6 times the average. Also, morphological patterns have changed: typical papillary cancer incidence has dropped by half while the diffuse follicular variety has grown 1.8-fold.

The purpose of this study was to determine prognostic factors for the recurrence of keratocystic odontogenic tumors (KCOTs) following simple enucleation by examining clinico-pathologic and immunohistochemical findings. Following enucleation, the frequency of recurrence among 32 subjects diagnosed with KCOT was analyzed for tumor site, radiographic and histologic features, and immunopositivity for Ki-67 and p53. Keratocystic odontogenic tumors in four out of 32 subjects (12.5%) recurred during the follow-up period (median: 33 months, range: 7-114 months). Three out of four subjects (75.0%) among recurrent group showed high expression of Ki-67 (LI >10%) in basal layer and four (4/28; 14.3%) among non-recurrence group (P = 0.025). Expression of p53 among non-recurrent group was observed in 11 subjects (11/28; 39.3%), and in three subjects (3/4; 75.0%) among the recurrent group (P = 0.295). Hazard risk for the recurrence of KCOT was 4.02 (95% CI 1.42-18.14) for high Ki-67 expression in the basal layer by the Cox proportional hazard model (P = 0.009). In our study, none of the other clinico-pathologic variables were associated with the recurrence of KCOT. The results suggested that the evaluation of Ki-67 expression in KCOT at the time of pathological diagnosis might be helpful for consideration of appropriate adjunctive surgical procedures to avoid a recurrence and may serve as a prognostic marker.

The clinical expression of bilirubin-induced neurological dysfunction varies according to severity and location of the disease. Definitions have been proposed to describe different bilirubin-induced neurological dysfunction subtypes. Our objective was to describe the severity and clinico-radiological-neurophysiological correlation in 30 consecutive children with bilirubin-induced neurological dysfunction seen over a period of 5 years. Thirty children exposed to acute neonatal bilirubin encephalopathy were included in the study. The mean peak total serum bilirubin level was 625 μmol/L (range 480-900 μmol/L). Acoustic brainstem responses were abnormal in 73% (n = 22). Pallidal hyperintensity was observed on magnetic resonance imaging in 20 children. Peak total serum bilirubin levels correlated with motor severity (P = .03). Children with severe motor impairment were likely to manifest severe auditory neuropathy (P bilirubin-induced neurological dysfunction subtype, and the majority of children had abnormal acoustic brainstem responses and magnetic resonance imaging. © The Author(s) 2016.

To identify the clinico-radiological features of patients with positive cultures for nontuberculous mycobacteria (NTM) and compare those to a sample of patients with tuberculosis (MTB). A laboratory database was used to retrieve all specimens submitted to King Khalid University Hospital, Riyadh, mycobacteriology laboratory for mycobacterial smears and cultures during the period from October 1999-April 2002. Using this database, the original records of the mycobacteriology laboratory and a review of the patient's health records, a standard proforma was completed that included demographic, clinical, radiological and laboratory information on patients included in this study. The patients were divided into 2 groups; the NTM group, which included patients with positive cultures for NTM and the MTB group, which included a sample of patients with documented tuberculosis. During the study period, 286 patients had positive mycobacterial cultures. Seventy patients (24.5%) grew NTM and 216 (75.5%) grew MTB. For patients with MTB, 54 patients were included as per the selection protocol of the study. There was no difference between the 2 groups in all measured demographic variables. The presence of weight loss and fever was significantly more in the MTB group. Radiologically, the presence of hilar adenopathy was more significant among patients with MTB than those with NTM (17% versus 4%, p=0.02). However, bronchiectatic changes were seen significantly more among NTM patients compared to patients with MTB (26% versus 11%, p=0.03). The isolation of NTM in the mycobacteriology laboratory is high. The clinico-radiological features were not sufficiently specific to differentiate patients with NTM from patients with MTB. Local studies are needed to explore NTM disease in various developing countries and identify the NTM species causing infections in non-immunosuppressed patients in each locality. (author)

To evaluate the clinico-pathologic features of intraocular osseous metaplasia. Pathology specimens of enucleated eyes submitted to the ophthalmic pathology service at a tertiary eye-care referral center between January 1995 and June 1999 were studied for intraocular osseous metaplasia. Specific histopathologic features noted in specimens with osseous metaplasia were the presence of retinal detachment, gliosis, retinal pigment epithelial hyperplasia, drusen, epiretinal membrane, fibrovascular proliferation and inflammation. Immunohistochemistry using monoclonal antibody against glial fibrillary acidic protein was performed to assess the glial component within the membranes and the proliferative vitreoretinal mass. Clinical records were reviewed and correlated with histopathologic findings. Osseous metaplasiaS was noted in 8 of 151 (5.2%) eyes examined. Clinical diagnosis in these was phthisis bulbi, staphyloma, absolute glaucoma and microphthalmos. Enucleation was performed for relief of symptoms (in painful blind eyes) or for cosmesis, and in an eye inciting sympathetic ophthalmia. Retinal detachment, gliosis and retinal pigment epithelial hyperplasia were noted in all the cases. Drusen with calcification or ossification (5 of 8), fibrovascular proliferation in the vitreous (5 of 8) and active inflammation (4 of 8) were the other associated histologic features. Location of ossification was subretinal in 3 cases, preretinal (ora serrata) in 1 case and in both locations in 4 cases. The eyes with subretinal osseous metaplasia had associated calcified drusen, while preretinal ossification was seen within the fibrovascular membranes. Chronic retinal detachment, hyperplasia and transdifferentiation of retinal pigment epithelium appear to be a few of the prerequisites for intraocular osseous metaplasia. Ossification can occur at isolated subretinal and preretinal locations or can involve both. Though a larger study is required to postulate the chronology of events, in

Full Text Available Abstract Background Epigenetic gene silencing is one of the major causes of carcinogenesis. Its widespread occurrence in cancer genome could inactivate many cellular pathways including DNA repair, cell cycle control, apoptosis, cell adherence, and detoxification. The abnormal promoter methylation might be a potential molecular marker for cancer management. Methods For rapid identification of potential targets for aberrant methylation in gynecological cancers, methylation status of the CpG islands of 34 genes was determined using pooled DNA approach and methylation-specific PCR. Pooled DNA mixture from each cancer type (50 cervical cancers, 50 endometrial cancers and 50 ovarian cancers was made to form three test samples. The corresponding normal DNA from the patients of each cancer type was also pooled to form the other three control samples. Methylated alleles detected in tumors, but not in normal controls, were indicative of aberrant methylation in tumors. Having identified potential markers, frequencies of methylation were further analyzed in individual samples. Markers identified are used to correlate with clinico-pathological data of tumors using χ2 or Fisher's exact test. Results APC and p16 were hypermethylated across the three cancers. MINT31 and PTEN were hypermethylated in cervical and ovarian cancers. Specific methylation was found in cervical cancer (including CDH1, DAPK, MGMT and MINT2, endometrial cancer (CASP8, CDH13, hMLH1 and p73, and ovarian cancer (BRCA1, p14, p15, RIZ1 and TMS1. The frequencies of occurrence of hypermethylation in 4 candidate genes in individual samples of each cancer type (DAPK, MGMT, p16 and PTEN in 127 cervical cancers; APC, CDH13, hMLH1 and p16 in 60 endometrial cancers; and BRCA1, p14, p16 and PTEN in 49 ovarian cancers were examined for further confirmation. Incidence varied among different genes and in different cancer types ranging from the lowest 8.2% (PTEN in ovarian cancer to the highest 56

Colon carcinomas with microsatellite mutator phenotype exhibit specific genetic and clinico-pathological features. This report describes the analysis of 63 "microsatellite instability-high" (MSI-H) tumors for the presence of mutations in microsatellites located in the coding regions (CDRs) of 6 genes: TGFbetaRII, BAX, hMSH3, hMSH6, IGFIIR, and BLM. The following frequencies of mutations were detected: TGFbetaRII (70%), BAX (54%), hMSH3 (36.5%), IGFIIR (22%), hMSH6 (17.5%), and BLM (16%). The overall picture revealed combinations of mutations suggestive of a progressive order of accumulation, with mutations of TGFbetaRII and BAX first, followed by frameshifts in hMSH3, hMSH6, IGFIIR, and BLM. Correlations with 12 clinico-pathological parameters revealed that tumors with frameshifts in 1 or 2 CDRs were significantly better differentiated than tumors with frameshifts in more than 2 CDRs. We also found that mutations in the hMSH3 gene were significantly associated with decreased wall invasiveness and aneuploidy, and frameshifts in the BLM gene were significantly associated with the mucinous histotype. A trend toward an association between hMSH3 and IGFIIR with the medullary and conventional adenocarcinoma histotypes, respectively, was seen. Our results strengthen the concept that mutations in target genes have a role in the tumorigenic process of MSI-H tumors, and indicate that frameshifts in microsatellites located in CDRs occur in a limited number of combinations that could determine distinct clinico-pathological traits.

The incidence of dengue is rising steadily in Malaysia since the first major outbreak in 1973. Despite aggressive measures taken by the relevant authorities, Malaysia is still facing worsening dengue crisis over the past few years. There is an urgent need to evaluate dengue cases for better understanding of clinic-laboratory spectrum in order to combat this disease. A retrospective analysis of dengue patients admitted to a tertiary care teaching hospital during the period of six years (2008 - 2013) was performed. Patient's demographics, clinical and laboratory findings were recorded via structured data collection form. Patients were categorized into dengue fever (DF) and dengue hemorrhagic fever (DHF). Appropriate statistical methods were used to compare these two groups in order to determine difference in clinico-laboratory characteristics and to identify independent risk factors of DHF. A total 667 dengue patients (30.69 ± 16.13 years; Male: 56.7 %) were reviewed. Typical manifestations of dengue like fever, myalgia, arthralgia, headache, vomiting, abdominal pain and skin rash were observed in more than 40 % patients. DHF was observed in 79 (11.8 %) cases. Skin rash, dehydration, shortness of breath, pleural effusion and thick gall bladder were more significantly (P  40 years (OR: 4.1, P hospitalization (OR: 2.3, P = 0.037) as independent predictors of DHF. Overall mortality was 1.2 % in our study. Current study demonstrated that DF and DHF present significantly different clinico-laboratory profile. Older age, secondary infection, diabetes mellitus, lethargy, thick gallbladder and delayed hospitalization significantly predict DHF. Prior knowledge of expected clinical profile and predictors of DHF/DSS development would provide information to identify individuals at higher risk and on the other hand, give sufficient time to clinicians for reducing dengue related morbidity and mortality.

Hypo-pituitarism results from impaired production of one or more of anterior pituitary trophic hormones. A rare cause of hypo-pituitarism is pituitary stalk transection syndrome. The MRI features of this condition in children and its association with hormonal deficiencies have been reported earlier. Reports on adults with this disorder are scarce, with only one small case series published in the recent literature. We studied the hormonal deficiency pattern and MRI findings of 12 patients with pituitary stalk transection syndrome who presented to our department between 2004 and 2011. Six patients were children and six were adults (≥18 years). This article compares the adult clinico-radiological phenotype of pituitary transection syndrome with the pediatric group of patients with same condition

Background: Abnormal vaginal discharge is a common clinical problem in reproductive age group. It is the second most common problem after abnormal uterine bleeding. It is a neglected health problem, most commonly caused due to vulvovaginal candidiasis, trichomoniasis, and bacterial vaginosis (BV). Objectives: The present study was conducted to determine the prevalence of common organisms causing vaginal discharge and also to know the variety of clinical presentation. Materials and Methods: A cross-sectional descriptive study was conducted in the Skin and STD Outpatient Department of Vinayaka Mission Kirupananda Variyar Medical College Hospital, Salem, who presented with abnormal vaginal discharge between September 2012 and September 2014. A total of 100 women in the reproductive age group who had symptoms of vaginitis were examined. Data were coded and analyzed. Results: Out of the 100 patients examined, 77 (77%) cases were organism positive. Among the positive cases, BV (27%) was the most common microbiological cause of abnormal vaginal discharge, followed by trichomoniasis (25%), vaginal candidiasis (22%), combined infection (Candida and BV) (3%), and nonspecific cases (23%). Conclusion: Out of 100 cases, few cases showed discordance between clinical and laboratory diagnosis. This discordance can be due to pitfalls in identifying the causative agent clinically or obscuring of the findings due to improper treatment received for other ailments. Thus, clinico-investigative correlation is more important than other clinical findings alone. PMID:28442807

Despite a steady increase in life expectancy, a few studies have investigated cross-sectional correlates and longitudinal predictors of cognitive function, a core domain of the successful aging, among socio-clinico-demographic factors in the oldest-old exclusively. The aims of this study were to examine socio-clinico-demographic characteristics associated with global cognition and its changes in the oldest-old. We reanalyzed a dataset of cognitively preserved community-dwelling subjects aged 85 years and older in the Tokyo Oldest Old Survey on Total Health, a 6-year longitudinal observational study. This study consisted of (1) baseline cross-sectional analyses examining correlates of global cognition (n = 248) among socio-clinico-demographic factors and (2) longitudinal analyses examining baseline predictors for changes of global cognition in 3-year follow-up (n = 195). The Mini-Mental State Examination was used as a screening test to assess global cognition. At baseline, higher weights were related to higher cognitive function in the oldest-old. The baseline predictors of global cognitive decline in 3-year follow-up were higher global cognition, shorter education period, and lower sociocultural activities and lower instrumental activity of daily living, in this order. The present study suggests that it is crucial to attain higher education during early life and avoid leanness or obesity, participate in sociocultural cognitive activities during late life, and maintain instrumental activity of daily living to preserve optimal cognitive function in the oldest-old, which will facilitate developing prevention strategies for cognitive decline and promoting successful aging in this increasing population.

Full Text Available Descrevem-se os achados clínicos e patológicos e os exames laboratoriais de filhotes de cães com diagnóstico post mortem de infecção por herpesvírus canino. Os casos ocorreram em duas propriedades da Cidade de Porto Alegre, Rio Grande do Sul, em abril de 2007 e julho de 2008. Clinicamente, os cães apresentaram anorexia, apatia, choro e dispneia. A morte dos cães ocorreu após 24-72 horas do início dos sinais clínicos. Na necropsia observaram-se hemorragia multifocal renal e hepatomegalia com petéquias e pontos brancos na superfície natural do fígado. Os pulmões se apresentaram não-colapsados e vermelhos. Havia esplenomegalia e, em alguns cães, petéquias na superfície capsular do baço. Aumento dos linfonodos mesentéricos e do timo foi observado. Lesões microscópicas incluíram hemorragia e necrose multifocal em células epiteliais tubulares renais, hepatócitos e tecidos linfoides. Nos pulmões, havia necrose alveolar multifocal acentuada com abundante material fibrinoso e infiltrado inflamatório misto de intensidade variada. Ocasionais corpúsculos de inclusão intranucleares em áreas periféricas à necrose foram identificados em hepatócitos, células epiteliais de túbulos renais e células alveolares. Amostras de fígado, rim e pulmão foram positivas na imunofluorescência direta para herpesvírus canino tipo 1 (CHV-1. O diagnóstico de infecção por herpesvírus foi baseado nos achados de necropsia, histológicos e de imunofluorescência positiva em tecidos usando anticorpo anti-CHV-1. De nosso conhecimento, este é o primeiro relato da identificação do CHV-1 no Brasil, embora achados clínico-patológicos anteriores já sugerissem a presença do agente na população canina do país.The clinic and pathological findings and laboratorial testing of puppies with postmortem diagnosis of canine herpesvirus infection are described.

Chordoma: review of clinico radiological features and factors affecting survival

International Nuclear Information System (INIS)

Soo, M.Y.S.

2001-01-01

This study reviews the clinico radiological features of cranial and sacrospinal chordomas and identifies factors affecting survival. Nineteen patients seen between January 1980 and December 2000 with histopathological diagnosis of chordomas were retrospectively reviewed with reference to clinical presentation, imaging features, treatment modalities and post-therapy status. Eight had tumours in the skull base while 11 patients had spinal and sacro-coccygeal lesions. Surgical resection was performed in 16 patients whose subsequent natural history was used to identify clinical indicators that may influence survival. Completeness of resection, age, gender and postoperative irradiation were subjected to analysis using the Cox proportional hazard models. Kaplan-Meir survival curves illustrate the survival distributions. Diplopia and facial pain are prime clinical presentations in cranial lesions, while extremity weakness and a sacrogluteal mass are common complaints in the sacrospinal group. Lesional calcifications are present in 40% while an osteolytic soft tissue mass is detectable by CT in all cases. Heterogeneous signals and internal septations on T 2 -weighted MRI are predominant features. In sacrospinal tumours, complete excision with adjuvant radiotherapy achieves the best results with a disease-free survival of more than 5 years. The clinical and imaging findings in this study are in accordance with those of other series. Except for complete surgical excision followed by radiotherapy in the subset of patients with sacrospinal tumours, none of the other clinical indicators show a statistical significant influence on survival.

Trapped neutrophil syndrome (TNS) is an autosomal recessive inherited neutropenia known in Border Collies since the 1990's. Recently, the causative mutation has been identified in the canine VPS13B gene and a DNA-based diagnosis has now become available. The present paper describes clinical and clinico-pathologic findings in a Border Collie with TNS that was molecularly diagnosed for the first time in Japan. In a 10-week-old male Border Collie with microgenesis and symptoms related to recurrent infections, a hematological examination revealed severe leukopenia due to neutropenia, suggesting the dog to be affected by inherited neutropenic immunodeficiency. Direct DNA sequencing demonstrated that the dog was homozygous for the causative mutation of TNS and both its parents were heterozygous carriers. In addition, a simple and rapid polymerase chain reaction-based length polymorphism analysis coupled with microchip electrophoresis was developed for the genotyping of TNS. This assay could discriminate clearly all genotypes, suggesting that it was suitable for both individual diagnosis and large-scale surveys for prevention.

Full Text Available In Slovenia like in other countries, till recently, personal history of epithelial ovarian cancer (EOC has not been included among indications for genetic counselling. Recent studies reported up to 17% rate of germinal BRCA1/2 mutation (gBRCA1/2m within the age group under 50 years at diagnosis. The original aim of this study was to invite to the genetic counselling still living patients with EOC under 45 years, to offer gBRCA1/2m testing and to perform analysis of gBRCA1/2m rate and of clinico-pathologic characteristics. Later, we added also the data of previously genetically tested patients with EOC aged 45 to 49 years.

Full Text Available Aim: The aim of this study was to determine the relevant tools in the diagnosis of liver cirrhosis in dogs. Material and Methods: A total of 140 dogs presented at Veterinary Teaching Hospital, Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, showing clinical signs of hepatic insufficiency were subjected to clinico-hemato biochemical, urological, ultrasonographic (USG, and USG guided fine-needle biopsy examinations by standard methods. On the basis of these results, 6 dogs out of 140 dogs were found to be suffering from liver cirrhosis. Six clinically healthy dogs constituted the control group. Results: The dogs suffering from liver cirrhosis manifested inappetence, halitosis, abdominal distension, weight loss, melena, icterus, anemia, and neutrophilic leukocytosis with the left shift. Levels of hemoglobin, lymphocytes, packed cell volume, mean corpuscular volume, mean corpuscular Hb (MCH, and platelet count were significantly lower in liver cirrhosis group than control group while total leukocyte count, neutrophils, and MCH concentration were significantly higher. Glucose, total protein, albumin, A/G ratio, and fibrinogen were significantly lower, and creatinine, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, prothrombin time, and APTT were significantly higher than the control values. Ultrasound revealed diffuse increase in echogenicity with rounded and irregular liver margins. Cytological examination of the ascitic fluid and fine-needle aspiration biopsy of liver was not fruitful in the diagnosis of liver cirrhosis. Conclusions: Liver cirrhosis causes clinical and hemo-biochemical alterations, which require special consideration when treating diseased animals. USG, diffuse increase in echogenicity of liver, rounding and irregularity of liver margins and microhepatica were the consistent findings. It is suggested that USG along with hemo-biochemical alterations may be used as a diagnostic tool for

Squamous cell carcinoma (SCC) is a common and important primary cutaneous malignancy. On skin biopsies, SCC is characterized by significant squamous cell atypia, abnormal keratinisation, and invasive features. Diagnostic challenges may occasionally arise, especially in the setting of small punch biopsies or superficial shave biopsies, where only part of the lesion may be assessable by the pathologist. Benign mimics of SCC include pseudoepitheliomatous hyperplasia, eccrine squamous syringometaplasia, inverted follicular keratosis, and keratoacanthoma, while malignant mimics of SCC include basal cell carcinoma, melanoma, and metastatic carcinoma. The careful application of time-honored diagnostic criteria, close clinico pathological correlation and a selective request for a further, deeper, or wider biopsy remain the most useful strategies to clinch the correct diagnosis. This review aims to present the key differential diagnoses of SCC, to discuss common diagnostic pitfalls, and to recommend ways to deal with diagnostically challenging cases

The number of HIV-positive immigrants have increased in Spain in the last few years, and now represent a significant proportion of the epidemic. Our objective is to describe the clinico-epidemiological characteristics of HIV-positive immigrants seen in a specialist unit in Madrid. Retrospective study. Every patient born in a country other than Spain and attended an HIV Unit in Madrid between 1992 and 2009 was included. Of the 371 patients included, 53.1% were Latin Americans, 24.5% Sub-Saharan Africans, and 22.4% others), and 60% were males. Immigrants represented 0.3% of new patients in 1992 and rose to 49.2% in 2009. The principal reason for HIV testing had been pregnancy/delivery among women (32.7%) and having a category-B disease among men (17.4%). Sexual transmission accounted for 92% of patients. Tuberculosis was the principal AIDS-diagnosing illness. Respectively 90%, 7.7%, 60%, 26.7%, 96% and 95% of patients had an IgG for HAV, HCV, Toxoplasma, Treponema, CMV and VZV. VHB-Ags+: 5.4%; PPD+: 17%. At least one syphilis episode was recorded in 62% of the men who have sex with men (MSM). Prevalence of HLA-B5701 was 6%, 0.9% and 3.8% in Caucasians, Amerindians and Afro-Americans, respectively. Immigrants represent a significant proportion of new HIV-positive patients. It is a very heterogeneous group according to their clinical and epidemiological characteristics. Copyright © 2011 Elsevier España, S.L. All rights reserved.

Former studies suggest the frequent coexistence of Hashimoto's thyreoditis with papillary thyroid cancer, frequently featured by multifocal carcinogenesis but lower clinical stages compared to thyroid cancers lacking thyroiditis. We examined the clinico-pathological correlations between Hashimoto's thyroditis and papillary thyroid cancer in our region in the North-Eastern part of Hungary. We included a total of 230 patients with papillary thyroid cancer who underwent thyroid surgery at the Surgical Department of the University of Debrecen. Patients' sex, age, multifocality of thyroid cancer and clinical stage were evaluated. Cases included 40 patients (17.4%) with (4 male, 36 female) and 190 (82.6%) patients without HT (44 male, 146 female). Hashimoto's thyroiditis related thyroid cancer was almost exclusively associated with the papillary histological type. Multifocality of papillary cancer was significantly more frequent with coexisting Hashimoto's thyroiditis (16/40; 40.0%) compared to cases uninvolved (45/190; 23.7%; p = 0.034). In contrast, lymph node metastasis was significantly less frequent among patients with Hashimoto's thyroiditis (4 pN1 [36.4%]; 7 pN0 [63.6%]) then without it (34 pN1 [82.9%]; 7 pN0 [17.1%]; p = 0.002). Higher frequency and multifocality of papillary thyroid cancer might be the consequence of preexisting Hashimoto's thyroiditis to be considered as a preneoplastic stimulus supporting carcinogenesis, though the exact pathomechanism of this correlation is not clear yet.

Intestinal-type gastric cancer (GC) still ranks among the high-incidence, highly lethal malignancies. Atrophic gastritis is the cancerization field in which GC develops. The current histological reporting formats for gastritis do not include any (atrophy-based) ranking of GC risk. To test the gastritis OLGA-staging (Operative Link for Gastritis Assessment) in prognosticating neoplastic progression. Ninety-three Italian patients were followed up for more than 12 years (range: 144-204 months). Clinical examinations, pepsinogen serology, endoscopy and histology (also assessing Helicobacter pylori status) were performed both at enrolment (T1) and at the end of the follow-up (T2). All invasive or intra-epithelial gastric neoplasia were consistently associated with high-risk (III/IV) OLGA stages. There was a significant inverse correlation between the mean pepsinogen ratio and the OLGA stage (test for trend; P gastritis OLGA-staging conveys relevant information on the clinico-pathological outcome of gastritis and therefore for patient management. According to OLGA-staging and H. pylori-status, gastritis patients could be confidently stratified and managed according to their different cancer risks.

Two numerical procedures, based on the Genetic Algorithm (GA) and the Simulated Annealing (SA), are developed to solve the problem of the expansion of capacity of a water resource system. The problem was divided into two subproblems: capital availability and operation policy. Both are optimisation-simulation models, the first one is solved by means of the GA and SA, in each case, while the second one is solved using the Out-of-kilter algorithm (OKA), in both models. The objective function considers the usual benefits and costs in this kind of systems, such as irrigation and hydropower benefits, costs of dam construction and system maintenance. The strength and weakness of both models are evaluated by comparing their results with those obtained with the branch and bound technique, which was classically used to solve this kind of problems. [Spanish] Un par de metodos numericos fundamentados en dos tecnicas de busqueda globales. Algoritmos Genetico (AG) y Recocido Simulado (RS), son desarrollados para resolver el problema de expansion de capacidad de un sistema de recursos hidricos.

Ambos modelos son de optimizacion-simulacion, el primero se realiza mediante los algoritmos del RS y el AG en cada caso, en tanto que el segundo lleva a cabo a traves del algoritmo del Out-of-kilter (AOK) en los dos modelos. La funcion objetivo con que se trabaja considera los beneficios y costos mas comunes en este tipo de sistema, tales como beneficios por riego, por hidroelectricidad y costos de construccion de los embalses y mantenimiento del sistema. La potencia y debilidades delos dos modelos se evaluan mediante la comparacion con los resultados obtenidos a traves de una de las tecnicas mas usadas en este tipo de problemas: la de ramificacion y acotacion.

We report clinico-pathological studies on the effect of preoperative hyperthermia and chemotherapy combined with radiotherapy (HCR) for progress of the local curability of advanced esophageal carcinoma. The subjects of these studies were 17 patients who underwent subtotal esophagectomy after preoperative irradiation of 40 Gy from 1980 to 1989, of which 8 patients had HCR, 6 patients irradiation only (R), 3 patients both irradiation and chemotherapy (CR). The clinical response rate of the patients with R or CR was 33% (PR 3, MR 3, NC 3), and the histological effective (Ef{sub 3} or Ef{sub 2}) rate was 56% (Ef{sub 3} 1, Ef{sub 2} 4, Ef{sub 1} 4). The clinical response rate of the patients with HCR was 88% (PR 7, MR 1), and the histological effective rate was 100% (Ef{sub 3} 1, Ef{sub 2} 7). HCR was more effective than R or CR for the local lesion of esophageal carcinoma histopathologically (p<0.05). However, the survival rate of patients with HCR was similar to R and CR, respectively. These results suggest that further improvement of the heating methods and the methods of combining hyperthermia with irradiation and chemotherapy is needed. (author).

2010-01-01

Maspin (mammary serine protease inhibitor) is a member of the serpin super family of protease inhibitors and is known to have tumor-suppressor function in breast and prostate cancers, acting at the level of tumor invasion and metastasis. However, there have been no published data regarding the role of Maspin in squamous cell carcinoma (SCC) and transitional cell carcinoma (TCC) of urinary bladder. Patients and Methods: We have evaluated the immunohistochemical expression of Maspin and p53 in a series of 134 bladder cancer patients (56 SCC and 78 TCC) and the interrelationship between Clinico pathological features and Maspin and p53 expression. Results: There was positive Maspin expression in 53.7% in all cases. In TCC, expression was found in 48/78 cases (61.5%). High Maspin expression was found in low grade (p<0.001) and advanced stage (p=0.02). In SCC, expression was found in 24/56 (42.8%). There was a statistically significant association between lost Maspin expression and grading (p=0.001). No correlation was found between Maspin expression and other Clinico pathological parameters including gender, clinical stage and Bilharzial infestation. These results indicated that Maspin expression might predict a better prognosis for bladder carcinoma. Also Maspin probably could play a role in tumor progression. p53 was positive in 70 cases (52.2%) of all patients evaluated. In TCC, it was positive in 36/78 cases (46.1%) and correlated with high grade (p=0.01) and advanced stage (p=0.01). In SCC, it was positive in 34/56 cases (60.7%). There was a statistically significant association between p53 expression and high grade (p=0.01) and advanced stage (p=0.01). There was an inverse correlation between the Maspin and p53 expression in TCC and SCC of bladder cancer. We found no significant association between both Maspin and p53 expression and bilharziasis in TCC and SCC; this indicated that Maspin and p53 expression could be prognostic factors in both bilharzial and non

The majority of US adult cancer patients today are diagnosed and treated outside the context of any clinical trial (that is, in the real world). Although these patients are not part of a research study, their clinical data are still recorded. Indeed, data captured in electronic health records form an ever-growing, rich digital repository of longitudinal patient experiences, treatments, and outcomes. Likewise, genomic data from tumor molecular profiling are increasingly guiding oncology care. Linking real-world clinical and genomic data, as well as information from other co-occurring data sets, could create study populations that provide generalizable evidence for precision medicine interventions. However, the infrastructure required to link, ensure quality, and rapidly learn from such composite data is complex. We outline the challenges and describe a novel approach to building a real-world clinico-genomic database of patients with cancer. This work represents a case study in how data collected during routine patient care can inform precision medicine efforts for the population at large. We suggest that health policies can promote innovation by defining appropriate uses of real-world evidence, establishing data standards, and incentivizing data sharing.

Full Text Available As famílias de classe C, D e E (Critério Econômico Brasil representam, aproximadamente, três quartos da população brasileira. Na década de 1990, esses consumidores começaram a despertar a atenção das empresas e dos estudiosos da área de marketing. Ainda assim, existem, até o momento, poucos estudos acadêmicos sobre esse tema. Este artigo se propõe efetuar uma revisão desses trabalhos, de cunho essencialmente descritivo e interpretativo, confrontando e discutindo seus achados dentro de uma perspectiva interpretativa. Seu objetivo é o de tentar avançar na interpretação dos resultados dessas pesquisas, buscando, assim, contribuir para a construção de novos estudos. O artigo está estruturado em torno dos temas abordados nos estudos analisados: classe social; gestão do orçamento; experiência da compra; e papel do preço e da marca nas decisões de compra. Traz, como conclusão, uma proposta de articulação dos elementos interpretativos encontrados nas pesquisas analisadas. Resumidamente, duas racionalidades parecem coexistir na formação das decisões de consumo: uma, "dura", material, derivada da escassez de recursos, que impõe uma racionalização estrita dos gastos; outra, de ordem simbólica, ancorada em elementos culturais e particularmente, nas dimensões relacionais e hierárquicas da sociedade brasileira, bem como em instituições de forte significado nessa sociedade, como a família e a religião.

Full Text Available OBJECTIVE: To describe HRCT findings in patients with bacterial pneumonia following bone marrow transplantation (BMT. METHODS: This was a retrospective study involving 30 patients diagnosed with bacterial pneumonia in whom HRCT of the chest was performed within 24 h after the onset of symptoms and the diagnosis was confirmed, based on a positive culture of sputum or bronchial aspirate, together with a positive pleural fluid or blood culture, within one week after symptom onset. There were 20 male patients and 10 female patients. The median age was 21 years (range, 1-41 years. The BMT had been performed for the treatment of the following: chronic myeloid leukemia, in 14 cases; severe aplastic anemia, in 6; acute myeloid leukemia, in 4; Fanconi's anemia, in 3; and acute lymphocytic leukemia, in 3. Two radiologists analyzed the HRCT scans and reached their final decisions by consensus. RESULTS: The most common HRCT findings were air-space consolidation (in 60%, small centrilobular nodules (in 50%, ground-glass opacities (in 40%, bronchial wall thickening (in 20%, large nodules (in 20%, pleural lesions (in 16.7% and tree-in-bud opacities (in 10%. The pulmonary lesions were distributed in the central and peripheral areas in 15 patients, whereas they were exclusively peripheral in 11. Lesions were located in the lower and middle lobes of the lung in 22 and 20 patients, respectively. CONCLUSIONS: The most common HRCT findings in our patient sample were air-space consolidation, small centrilobular nodules and ground-glass opacities, most often in the central and peripheral regions of the middle and lower lung zones.OBJETIVO: Descrever os achados de TCAR em pacientes com pneumonia bacteriana após transplante de medula óssea (TMO.

There is critical need for improved biomarker assessment platforms which integrate traditional pathological parameters (TNM stage, grade and ER/PR/HER2 status) with molecular profiling, to better define prognostic subgroups or systemic treatment response. One roadblock is the lack of semi-quantitative methods which reliably measure biomarker expression. Our study assesses reliability of automated immunohistochemistry (IHC) scoring compared to manual scoring of five selected biomarkers in a tissue microarray (TMA) of 63 human breast cancer cases, and correlates these markers with clinico-pathological data. TMA slides were scanned into an Ariol Imaging System, and histologic (H) scores (% positive tumor area x staining intensity 0–3) were calculated using trained algorithms. H scores for all five biomarkers concurred with pathologists’ scores, based on Pearson correlation coefficients (0.80–0.90) for continuous data and Kappa statistics (0.55–0.92) for positive vs. negative stain. Using continuous data, significant association of pERK expression with absence of LVI (p = 0.005) and lymph node negativity (p = 0.002) was observed. p53 over-expression, characteristic of dysfunctional p53 in cancer, and Ki67 were associated with high grade (p = 0.032 and 0.0007, respectively). Cyclin D1 correlated inversely with ER/PR/HER2-ve (triple negative) tumors (p = 0.0002). Thus automated quantitation of immunostaining concurs with pathologists’ scoring, and provides meaningful associations with clinico-pathological data.

Full Text Available Background: The ABO blood group system is of prime significance in red cell transfusion and organ transplantation. However, ABO compatibility is not critical in allogenic hemopoietic stem cell transplantation (HSCT and approximately 40-50% of hemopoietic stem cell transplants are ABO incompatible. This incompatibility may be major, minor or bi-directional. Though there are descriptions of transfusion practice and protocols in ABO incompatible HSCT, there are considerable variations and transfusion support in these patients can be very challenging. Aims: The immunohematologic observations in two cases of bi-directional ABO incompatible HSCT have been described, and clinico-serologic correlation has been attempted. Materials and Methods: In both cases, peripheral blood stem cell harvests were obtained using the Cobe spectra cell separator. Immunohematologic assessments in the donor and recipient were done as a part of pre HSCT evaluation. Both the standard tube technique and column agglutination method (Ortho Biovue Micro Bead System was used. Antibody screen was done by column agglutination method using three cell panel (Surgiscreen cells. Isoagglutinin titration was done by the master dilution method and standard validated techniques were used. Results: The pattern of laboratory findings in the two cases was different and so were the clinical outcomes. Although there was early engraftment in the first case, the second case developed pure red cell aplasia and this was well-reflected in the immunohematologic assessments. Conclusion: Immunohematologic assessment correlated well with the clinical picture and could be used to predict clinical outcome and onset of complications in ABO incompatible HSCT.

2009-01-01

Angiogenesis and lymphangiogenesis are essential for breast cancer growth and progression. This study aimed at investigating lymphatic micro vessel density (LVD) and microvessel density (MVD) as prognostic markers in breast carcinoma. Forty breast carcinomas were immuno stained for D2-40, CD31 and VEGF. Median lymphatic and blood micro vessel densities, as well as VEGF expression, were related to each other and to clinico pathologic parameters including lymph node (Ln) status. The efficacy of haematoxylin and eosin (H and E) in detecting lymphatic vessel invasion (LVI) compared to D2-40 immunostaining was also investigated. D2-40 stained normal lymphatic endothelium and myoepithelial cells, but with different staining patterns. D2-40 LVD related significantly to CD31 counts (r=0.470; p=0.002), and LN metastasis (Mann-Whitney U=101.500; p=0.043); however, it did not relate to age, tumor grade, tumor size or LVI. D2-40 identified LVI in 3 more cases (7.5%) than those detected by H and E. VEGF was expressed in 85% of cases, and was significantly related to CD31 and D2-40 counts (p=0.033 and 0.007, respectively). In conclusion, D2-40 LVD showed a significant association with LN metastasis, and can be considered to segregate patients with positive from those with negative LNs. D2-40 enhances the detection of LVI relative to H and E staining reflecting a potential for lymphatic metastatic spread and possible poor prognosis

To determine the clinical and the pathologic significance of the focal attenuation differences (FAD) and bile duct wall enhancement occurring in recurrent pyogenic cholangitis (RPC) and seen at multiphasic spiral CT. Among the multiphasic (non-contrast, arterial and portal or delayed phase) spiral CT findings of 60 consecutive patients, two types of FAD were noted during the non-contrast phase. These were Type A (iso) and Type B (low attenuation), and their distribution pattern (lobar versus patchy, multifocal) and the and the presence or absence of bile duct wall enhancement were recorded. The radiologic findings were correlated with the clinical and pathologic findings. Two types of FAD were noted in 40 of the 60 patients. Active in flammation was present in 19 of the 27 with Type-A and in ten of the 15 in whom the presence of RPC was pathologically proven. Ten of the 13 with Type-B FAD were in a subclinical state, and nine of the ten in whom RPC was pathologically proven had chronic inflammation. Among 20 patients who did not have FAD, RPC was subclinical in 18 and dormant in nine of the eleven in whom its presence was pathologically proven (p<0.001). Clinico-pathologic correlation with bile duct wall enhancement and the distribution pattern of FAD showed no statistical significance. The inflammatory activity of RPC can be predicted by analysis of the FAD seen at multiphasic spiral CT

The diagnosis of jaw bones using X-ray computed tomography (CT) is important to determine placement of dental implants. A Clinico-statistical study were made on 490 cases which applied preoperative dental mutiplannar reconstructing CT (dental MPR) imaging for dental implant treatment in Iwate Medical University Hospital, during a five-year period from 2002 to 2006. The following results were obtained: The 490 cases consisted of 179 males and 311 females. They ranged in age from 16 to 80 years, the average age was 53.6 years old. The largest number of cases were in their 50's and, in most generations, there were more female cases than male. Similar cases have been increasing every year. Most patients were referred from other clinics to our hospital. Of the cases that underwent CT scanning more were mandible than maxilla. Implantation prearranged region revealed a predominance of mandible in anterior teeth, and maxilla in molar teeth. The cases that were using diagnostic surgical stents increased in the first three years, but were constant afterwards. (author)

The SteatoTest, fatty liver index (FLI) and hepatic steatosis index (HSI) are clinico-biological scores of steatosis validated in general or selected populations. Serum adiponectin (s-adiponectin) and retinol binding protein 4 (s-RBP4) are adipokines that could predict liver steatosis. We investigated whether the Steatotest, FLI, HSI, s-adiponectin and s-RBP4 could be valid predictors of liver steatosis in type-2 diabetic (T2D) patients. We enrolled 220 consecutive T2D patients. Reference standard was 3.0 T 1 H-MR spectroscopy (corrected for T1 and T2 decays). Intraclass correlation coefficients (ICCs), Kappa statistic measures of agreement, receiver operating characteristic (ROC) curves were assessed. Median liver fat content was 91 mg triglyceride/g liver tissue (range: 0-392). ICCs among the Steatotest, FLI, HSI, s-adiponectin, s-RBP4 and spectroscopy were low: 0.384, 0.281, 0.087, -0.297 and 0.048. Agreement between scores and spectroscopy was poor (Kappa range: 0.042-0.281). The areas under the ROC curves were low: 0.674, 0.647, 0.637, 0.616 and 0.540. S-adiponectin and s-RBP4 levels were strongly related to the presence of diabetic nephropathy (P = 0.0037 and P = 0.004; Mann-Whitney). The SteatoTest, FLI, HSI, s-adiponectin, s-RBP4 are not valid predictors of steatosis in T2D patients. Clino-biological markers cannot replace 1 H-MR spectroscopy for the assessment of liver fat in this population. (orig.)

In April 2006, a new affiliated hospital opened at Nihon University School of Dentistry at Matsudo, and the latest model was introduced into the department of radiology. CT examinations for preoperative dental implant going on 64 multi-detector row CT, the number of cases has increased. CT examination is useful for preoperative dental implant, and many studies of concerning clinical studies using CT images have been reported. The purpose of this study was to the clinico-statistical studies of preoperative CT examinations for dental implant at our radiology department using 64 multi-detector row CT. The subjects consisted of 5174 regions in 1312 cases of preoperative CT examinations, between April 2006 and December 2007. CT machine used was the Aquilion TM 64 (Toshiba Medical Systems, Japan), and the workstation used was the ZIOSTATION (ZIOSOFT, Japan). All of CT examinations were performed the position of implant placement and disease examined from CT findings. The following results were obtained: The 1312 cases consisted of 426 males and 886 females. Patient age ranged from 16 yrs to 86 yrs old, the average age were 55.5 yrs old. Six hundred and seventy four cases were ordered at another private dental office not our hospital, and 638 cases were ordered at our hospital. The numbers of implant placement were on the average of 3.9, and the rate got higher with age. The lesions which detected by preoperative CT examination were maxillary sinusitis, periodontitis, ectopic calcification, and mucous retention cyst. (author)

Apresentamos o caso clínico de um homem de 45 anos de idade, assintomático, com antecedentes de traumatismo do baço consequente a um acidente de viação aos 18 anos de idade. O doente foi enviado a consulta de Pneumologia por achados imagiológicos compatíveis com nódulos pleurais no hemitórax esquerdo, mas a análise histopatológica das referidas lesões demonstrou tratar-se de tecido esplénico. O tratamento dos remanescentes esplénicos é conservador. Estes podem adquirir função imunológica, independentemente do local onde estão implantados, e proteger o organismo de eventuais infeções. Summary: Thoracic splenosis is a rare, benign condition that results from the rupture of the spleen associated or not to diaphragm injury, usually asymptomatic and incidentally diagnosed after performing imaging exams for other reasons. We present the case of a 45-year-old male, asymptomatic, with splenic trauma history subsequent to a traffic accident at 18 years of age. The patient was sent to Pneumology consultation due to imaging findings consistent with pleural nodules in the left hemithorax, but histopathological examination of these lesions showed the presence of splenic tissue. The treatment of splenic remnants is conservative. These can acquire immune function, regardless of their location, and protect the patient from possible infections.

Non-metastatic clear-cell renal cancer: dependence of the tumour stage on clinico-anatomic and morphologic factors; prognostic value of macro- and karyometric characteristics Sankt Peterburg Pathology Bureau, Sankt Peterburg It was shown based on multivariate regression analysis that pT1a3bN0MO stages of non-metastatic clear-cell renal cancer significantly correlate not only with the tumor size and invasion into the fatty tissue and/or renal vein but also with the invasion into the renal capsule and with the mean maximum diameter and mean nucleus area of tumor cells. There was no correlation of clear-cell renal cancer stages with tumor proliferative activity, gene p53 mutation, oncosuppressor gene PTEN expression, fraction of tumour clear-cell component, and such clinical characteristics as patients' sex, age, and body mass index. Taking into account statistically significant differences between the patients' survival rates, the regression equations developed in this work may be used for the prediction of disease outcome.

Full Text Available Medication adherence contributes significantly to symptom remission, recovery and wellbeing in mental illnesses. We evaluated how medication adherence correlates with clinico-demographic factors and quality of life (QoL in a sample of Nigerians with schizophrenia. This descriptive crosssectional study involved 160 randomly selected participants with confirmed diagnosis of schizophrenia based on MINI International Neuropsychiatric Interview. Data on socio-demographic and clinical characteristics of participants were collected with a questionnaire. Medication adherence was assessed with Morisky Medication Adherence Questionnaire, and participants completed the World Health Organization Quality of Life Scale-BREF. The mean age of participants was 38.54 (±11.30 years, and all the participants were on antipsychotics, but only 45% were adherent to their medication. Out of all the participants, 45 (28.2% considered their overall QoL to be good, 97 (60.6% considered theirs to be fair, while 18 (11.2% reported poor QoL. Medication non-adherence correlated negatively with good QoL across multiple dimensions including overall QoL (r=- 0.175, health satisfaction (r=-0.161, physical (r=-0.186 and psychological domain (r=-0.175. Again, participant’s age (r=- 0.190 and age of onset of illness (r=-0.172 correlated negatively with medication nonadherence, and a trend towards relapse delay with medication adherence was also observed (r=-0.155. The effect size of these correlations were however small. Our findings suggest a link between medication adherence and QoL in schizophrenia, such that strategy that addresses medication nonadherence and its determinants may have potential benefits on wellbeing. Further hypotheses-driven studies are desirable.

The SteatoTest, fatty liver index (FLI) and hepatic steatosis index (HSI) are clinico-biological scores of steatosis validated in general or selected populations. Serum adiponectin (s-adiponectin) and retinol binding protein 4 (s-RBP4) are adipokines that could predict liver steatosis. We investigated whether the Steatotest, FLI, HSI, s-adiponectin and s-RBP4 could be valid predictors of liver steatosis in type-2 diabetic (T2D) patients. We enrolled 220 consecutive T2D patients. Reference standard was 3.0 T {sup 1}H-MR spectroscopy (corrected for T1 and T2 decays). Intraclass correlation coefficients (ICCs), Kappa statistic measures of agreement, receiver operating characteristic (ROC) curves were assessed.

Neuroendocrine tumours occur very rarely in the ampulla of Vater and their clinical behaviour is unknown. The aim of this study is to assess the clinico-pathological features, surgical approach and prognosis of these patients. Six patients with neuroendocrine tumours of the ampulla of Vater treated with curative intent surgery at a single centre were retrospectively analysed. A univariate analysis of potential prognostic factors was also performed (data provided from the present study and literature review). Pancreaticoduodenectomy was curative in all the patients. Overall and disease-free survival rates were significantly better for G1/G2 tumours (p = 0.006 and p = 0.004, respectively). Although frequent, lymph node metastases did not influenced both overall (p = 0.760) and disease-free survival rates (p = 0.745). No significant differences of survival were observed in patients with ENETS stage I/II disease, as compared to ENETS stage III disease (p = 0.169 and p = 0.137, respectively). No differences were observed according to UICC staging system (p = 0.073 and p = 0.177, respectively). Tumours that are less than 2 cm or limited to the ampulla appear to have a better prognosis. The WHO 2010 classification appear to accurately predict patient prognosis, while the ENETS or UICC staging systems have a limited value (especially in regard to lymph node metastases). Radical surgery (i.e. pancreaticoduodenectomy with lymphadenectomy) should be the standard approach in most patients with NET of the ampulla of Vater because this procedure removes all the potential tumour-bearing tissue.

Objective: To analyze clinico pathological presentation of tongue cancers and to calculate survival rates (SR) with disease free survival rates (DFSR) and recurrence rates (RR) in different treatment modalities and to compare the results of surgery alone and radiotherapy alone in stage I and stage II disease and to calculate better option of treatment in early tongue cancers. Design: A longitudinal study. Place and Duration of Study: Department of Otolaryngology and Head and Neck Surgery, Pakistan Institute of Medical Sciences, Islamabad (PIMS) from January 1987 to June 1998. Patients and Methods: Case histories of 67 patients were collected from departmental record. Clinical data included age at diagnosis, gender of patient, location of tumor, presenting symptoms and their duration, biopsy report, predominant histological pattern of tumor, nodal status, stage of tumor, treatment modality employed, tumor recurrence, metastasis and survival rates with disease-free survival rates after 2 years' follow-up. Results: Among 67 patients there were 31 males and 36 females. Mean age was 50 years (range 20 - 80 years). Sixty seven patients with primary cancer of tongue constituted 38.8% of oral cavity cancers during period of 1987 - 1998 in PIMS. Smoking, poor oro dental hygiene (POOH) and betel nuts chewing were the main risk factors. Odynophagia and painful ulcers on lateral border of tongue were the main clinical symptoms with average duration of 7 months. Regional lymph nodes were palpable in 32.8%, 5.5% was in stage I, 35.8% in stage II, 29.8% in stage III, and 28.3% was in stage IV. No patient was found to have distant metastasis. Histopathology in 94% of cases was squamous cell carcinoma (SCC). Recurrence and survival rates were determined in 49 patients. Average time of recurrence was 12.5 months. Recurrence was 100% loco regional (LR). It was 85.7% in patients treated with radiotherapy (RT) alone, 42.1% in patients treated with surgery alone and 31.2% in patients

In this work it is presented for the first time in the literature the solution of the problem of the planning the expansion of an electrical transmission network (PERTE) with the use of the Evolutionary Programming. The evolutionary programming is a stochastic method of optimization with similar characteristics to the generic algorithms, but different. During the development of this work it is shown what each one of these two heuristic methods of optimization consist of. Additionally, the main characteristics of other two heuristic methods known in the literature are described (Tabu Searching and Simulated Annealing). These two methods together with the genetic algorithms and decomposition of Benders have also been used to solve the problem of planning PERTE. The operation of the proposed algorithm of evolutionary programming was tested in two networks of electrical transmission. The first case of test is a system which is known in the literature. The second case is a representative system of the electrical transmission network of Central America. The results obtained improve all the results shown when applying different heuristic methods of optimization (genetic algorithms, simulated annealing and Tabu searching) to solve the same problem.

Diffuse hair loss (DHL) is a common problem in adult women and has a major impact on quality of life. Ascertaining the etiological diagnosis is a challenging task in such patients. Satisfactory treatment can only be instituted after ascertaining the cause of hair loss. To study the clinico-epidemiological profile of nonscarring DHL in females and to ascertain its underlying etiological factors. Of a total of 110 females, who presented with nonscarring DHL to the outpatient dermatology department, 100 qualified for inclusion in the study. A detailed history, clinical examination, and laboratory investigations were performed in all the patients. Statistical analysis was performed on the data collected. Of 100 cases of DHL which were included in the study, commonest was chronic telogen effluvium (CTE) (62%), followed by female pattern hair loss (FPHL) (22%) and acute telogen effluvium (ATE) (16%). Incidence of hair loss was highest in 21-40 years age group. Psychological stress was seen to be a precipitating factor in 18 patients and found most commonly in women belong to CTE group (n-16, 25.8%). Hemoglobin levels ranged from 80 to 142 gm/L (mean: 119 ± 110). Low hemoglobin level (hair loss, and their supplementation may be needed for a faster regrowth of hair in all cases of hair loss irrespective of the pattern. © 2018 Wiley Periodicals, Inc.

Full Text Available PURPOSE: To describe and evaluate normal rat temporomandibular joints from anatomic and histopathologic point of view and make a comparison between this joint in rats and humans. METHODS: Twelve male adult Wistar rats (12 same side joints were used in this procedure. The following anatomical structures were histologically evaluated in a qualitative fashion: condyle, disc, temporal bone, retrodiscal tissue and synovia. The macroscopical and microscopic study of the human TMJ was based on the current literature. RESULTS: The TMJ is surrounded by a thin capsule, consisting of fibrous tissue, and a synovial lining. The mandibular angle has a prominent shape. The glenoid fossa is flat, with no eminences. Histologically, the TMJ is composed of different tissues that comprise the mandibular head, mandibular fossa and fibrocartilaginous disc. A layer of hyaline cartilage covers the articulating cortical condyle and temporal bone. CONCLUSION:Morphologically and histologically, the articular structure of rats is, on the whole, similar to that of humans. In these animals there is no articular eminence.OBJETIVO: Descrever e avaliar a articulação temporomandibular de ratos sob o aspecto anatômico e histológico e realizar uma comparação entre esta articulação e a de humanos.

The objective of our study was to ascertain racial/ethnic disparities in Asian/Pacific Islanders (API) for non-small-cell lung cancer (NSCLC) clinico pathologic features and survival outcomes based on various tumor characteristics and treatment modalities. Method. SEER database identified invasive NSCLC cases from 2004 to 2010. Variables included American Joint Committee on Cancer (AJCC) stage 7, tumor grade, tumor size, histology, age, marital status, radiation, surgery, and reason for no surgery. The Kruskall-Wallis test and the Z test were used to examine differences between races/ethnicities and the referent, non-Hispanic white (NHW). Multivariate Cox proportional analyses were used to establish the weight of the prognostic significance contributing to disease-specific survival (DSS) in each AJCC stage. Result. Improved DSS was seen in API across stage I (HR: 0.78), stage II (HR: 0.79), and stage IV (HR: 0.86), respectively, compared to the referent NHW (P<0.01). being female gender, AIS histology, and birth outside the US (P<0.01). Conclusion. We have demonstrated improved survival among API in early stage and stage IV NSCLC. Further research is necessary to clarify the role of lifestyle and tumor biology for these differences.

Background and Objective: Survivin is a novel member of the inhibitor of apoptosis (IAP) gene family. It is associated with more aggressive behavior and parameters of poor prognosis in most human cancers including gastric, colorectal and bladder carcinomas. However, conflicting data exist on its prognostic effect in breast cancer. This current study is designed to assess survivin expression in breast carcinoma relating results with clinico pathological parameters, proliferation (MIB-1) and molecular classification. Material and Methods: Our retrospective study com- prised of 65 archived cases of breast carcinoma. Samples from the tumor and the adjacent normal breast tissue were immuno stained for survivin and MIB-1. Nuclear and cytoplasmic survivin expression was evaluated in normal breast tissue and carcinoma regarding both the intensity and the percentage of positive cells. ER, PR, HER2 were used as surrogate markers to classify the cases into four molecular subtypes. Results: Survivin expression was detected in 78.5% of breast carcinomas. The adjacent normal breast tissue was immuno negative. Survivin expression showed significant association with increased tumor size ( p <0.0001), high histologic grade ( p =0.04), lymph node metastases ( p <0.001), advanced tumor stage ( p <0.0001), MIB-1 expression ( p =0.02), negative estrogen receptor status ( p =0.01) and negative progesterone receptor status ( p <0.0001). The subcellular localization of survivin significantly related to histologic grade, stage and lymph node involvement. The percentage of TNP (triple negative phenotype) and HER2+/ER-PR- tumors expressing survivin were significantly higher compared to the Luminal subtypes ( p =0.01). Conclusion: Survivin expression was associated with parameters of poor prognosis in breast cancer. Moreover, the cancer-specific expression of survivin, coupled with its importance in inhibiting cell death and in regulating cell division, makes it a potential target for novel

This study provides comprehensive information on the past and current status of the Andean cutaneous leishmaniasis (Andean-CL, uta) in Peru and Ecuador, mainly focusing on the causative Leishmania parasites and clinico-epidemiological features. Available information and data including our unpublished works were analyzed thoroughly. Endemic regions of the Andean-CL (uta) in Peru run from the north Piura/Cajamarca to the south Ayacucho at a wide range of the Pacific watersheds of the Andes through several departments, while in Ecuador those exist at limited and spotted areas in the country's mid-southwestern two provinces, Azuay and Chimborazo. The principal species of the genus Leishmania are completely different at subgenus level, L. (Viannia) peruviana in Peru, and L. (Leishmania) mexicana and L. (L.) major-like (infrequent occurrence) in Ecuador. The Peruvian uta is now prevalent in different age and sex groups, being not clearly defined as found in the past. The precise reasons are not known and should be elucidated further, though probable factors, such as emergence of other Leishmania parasites, non-immune peoples' migration into the areas, etc., were discussed briefly in the text. The Andean-CL cases in Ecuador are more rural than before, probably because of a rapid development of the Leishmania-positive communities and towns, and the change of life-styles of the inhabitants, including newly constructed houses and roads in the endemic areas. Such information is helpful for future management of the disease, not only for Leishmania-endemic areas in the Andes but also for other endemic areas. Copyright © 2017 Elsevier B.V.

Background: Alcoholism is a health problem not only in developed countries but also in developing countries. Cirrhosis due to alcohol is a common cause of death among individuals abusing alcohol. A better knowledge of the spectrum of alcoholic liver diseases, its clinical, biochemical and histopathological features could result in early detection and prevention of alcoholic liver diseases before it’s catastrophic and life threatening effects. Materials and Methods: A total of 200 patients with alcoholic liver diseases were studied with respect to alcohol consumption, clinical features, biochemical and histopathological changes. The clinical features, biochemical parameters, and histopathology of liver including Ishak’s modified histological activity index (HAI) were correlated with the amount and duration of alcohol consumed. Result: Majority of the patients were in the age group of 40-49 years and all the cases were males. Majority consumed alcohol of about 75-90 grams per day for a duration of 10–12 years. Anorexia and jaundice were the most common symptom and clinical finding respectively. Hyperbilirubinemia and hypoalbuminemia were the most common abnormalities observed in liver function tests. Advanced HAI stages with features of cirrhosis were most frequent histo-pathological finding noted in this study. Clinico-biochemical profile was significantly correlated with degree of alcohol ingestion as well as with liver histopathology. Conclusion: The wide prevalence of alcoholic liver disease including cirrhosis among Indian males was noted with significantly lower quantity and duration of alcohol ingestion. The severity of liver damage is directly proportional to the quantity and duration of alcohol consumed. Clinical features and biochemical changes may forecast the liver histopathology among the patients of alcoholic liver disease. PMID:25478382

Validation of the prognostic gene portfolio, ClinicoMolecular Triad Classification, using an independent prospective breast cancer cohort and external patient populations

2014-01-01

Introduction Using genome-wide expression profiles of a prospective training cohort of breast cancer patients, ClinicoMolecular Triad Classification (CMTC) was recently developed to classify breast cancers into three clinically relevant groups to aid treatment decisions. CMTC was found to be both prognostic and predictive in a large external breast cancer cohort in that study. This study serves to validate the reproducibility of CMTC and its prognostic value using independent patient cohorts. Methods An independent internal cohort (n = 284) and a new external cohort (n = 2,181) were used to validate the association of CMTC between clinicopathological factors, 12 known gene signatures, two molecular subtype classifiers, and 19 oncogenic signalling pathway activities, and to reproduce the abilities of CMTC to predict clinical outcomes of breast cancer. In addition, we also updated the outcome data of the original training cohort (n = 147). Results The original training cohort reached a statistically significant difference (p risk groups. Conclusions Both prospective internal cohorts and the independent external cohorts reproduced the triad classification of CMTC and its prognostic significance. CMTC is an independent prognostic predictor, and it outperformed 12 other known prognostic gene signatures, molecular subtype classifications, and all other standard prognostic clinicopathological factors. Our results support further development of CMTC portfolio into a guide for personalized breast cancer treatments. PMID:24996446

MÉTODOS: Trabalho retrospectivo, realizado num Banco de Olhos (BOO entre janeiro de 2006 e junho de 2011, usando dados de prontuários a partir das informações enviadas pelos cirurgiões e sendo examinado material recebido de ceratoplastia penetrante com o exame de 38 peças de 35 pacientes, sendo processadas e feitas de uma a três colorações de acordo com as dificuldades diagnósticas. RESULTADOS: Os pacientes eram na maioria homens, 57% (n=35, a faixa etária acima de 60 anos a mais numerosa com 1/3 dos pacientes. Os casos de ceratite fúngica correspondiam à média de 6,4% (n=597 do material recebido no BOO e 1,65% (n=2310 dos transplantes ocorrido com o material fornecido nos últimos 5 anos. Pelas informações dos cirurgiões 39,5% (n=38 dos casos deviam-se a perfuração corneana. Usando as datas dos transplantes foi feita uma Tábua de Observação. Em 11 (n=38 casos, a córnea procedia de transplante anterior. As formas leveduriformes nos tecidos corneanos eram de 63% (n=38. Em 50% (n=38 dos casos o infiltrado inflamatório era pequeno ou inexistente. A camada de Descemet estava íntegra em 13% (n=38, enquanto eram encontrados fungos na superfície corneana de 45% (n=38 dos casos. CONCLUSÃO: A coleta do material poderá ser feita com sucesso mesmo depois de instalado o tratamento, entretanto, nas úlceras de córnea deve ser feito preferentemente a coleta de material com espátula para exame laboratorial e a microscopia confocal in vivo. A predominância das leveduras poderá ser devido a alterações morfológicas do fungo sofridas no tecido corneano. A penetração intraocular é facilitada por alterações da Camada de Descemet e pela própria capacidade do fungo de penetrar nos tecidos

This study evaluates the correlation between body mass index (BMI) and clinico pathological parameters of metastatic prostate cancer (MPC) and its impact on survival. Method During the study period, 71 MPC patients were eligible. Patients with BMI < 25.0 kg/m2 were categorized as level I and patients with BMI ⩾ 25.0 kg/m2 were categorized as level II. Demographic features and survival rates were evaluated by the Kaplan–Meier method and Cox proportional models. Results 31 patients belonged to level I while the rest belonged to level II with insignificant higher median follow-up duration in level II; ρ=0.5. In terms of age, metastasis, serum level of albumin, prostatic specific antigen, alkaline phosphatase (AKP) and Gleason score, there was no significant difference between the two levels. The cumulative survival probability in the 12th, 24th and 36th month in level I vs; level II was; 86.7%, 68.7%, 64.1% vs; 74.4%, 67.7%, 55.1%, respectively with 7 patients dead in level I compared to 14 patients dead in level II denoting a higher PC-specific death rate in the level II group. In univariate and multivariate analysis, poor prognosis was associated with increasing AKP (HR = 1.0005, 95% CI, p = 0.03; HR=1.001, 95% CI, ρ=0.03) respectively, while better prognosis was associated with no visceral metastasis (HR = 0.09, 95% CI, ρ=0.000; HR = 0.04, 95% CI, ρ=0.000) and increasing albumin levels (HR = 0.17, 95% CI, ρ=0.000; HR = 0.15, 95% CI, ρ=0.000) respectively. In multivariate analysis only, patients belonging to level I were associated with better prognosis (HR = 0.17, 95% CI, ρ=0.02). Conclusion BMI is dependent on prognostic factors in patients with MPC

Materials and Methods: This study included all patients who were referred for CL psychiatry from among the inpatients in the hospital and the emergency department (during off working hours of the hospital over a period of 1 year. Data were obtained and analyzed in terms of where was the referral placed, by whom, the reason for placing the referral, the primary medical/surgical diagnosis of the patient, the presenting complaints, any past psychiatric history, the psychiatric diagnosis (as per the International Classification of Diseases, Tenth Edition, the investigations advised and their reports, the treatment advised (psychotherapeutic and psychopharmacological, the sociodemographic profile of the patients, and the follow-up details. Results: A total of 157 patients were referred to the CL unit over the study period. Out of these, 125 patients were referred among the inpatients and 32 from the emergency department of the hospital. Majority of the patients were in the age group of 25–50 years and were male. The majority of the referrals were made by general physician; most of the referrals were placed from emergency department. The most common reason for referral was for altered sensorium and behavioral abnormalities. The most common diagnosis was delirium followed by depressive episode and alcohol dependence syndrome. Conclusion: There was higher representation of delirium and alcohol-related cases in our study compared to older studies.

Full Text Available Abstract Background Studies of several tumour types have shown that expression profiling of cellular protein extracted from surgical tissue specimens by direct mass spectrometry analysis can accurately discriminate tumour from normal tissue and in some cases can sub-classify disease. We have evaluated the potential value of this approach to classify various clinico-pathological features in colorectal cancer by employing matrix-assisted laser desorption ionisation time of-flight-mass spectrometry (MALDI-TOF MS. Methods Protein extracts from 31 tumour and 33 normal mucosa specimens were purified, subjected to MALDI-Tof MS and then analysed using the 'GenePattern' suite of computational tools (Broad Institute, MIT, USA. Comparative Gene Marker Selection with either a t-test or a signal-to-noise ratio (SNR test statistic was used to identify and rank differentially expressed marker peaks. The k-nearest neighbours algorithm was used to build classification models either using separate training and test datasets or else by using an iterative, 'leave-one-out' cross-validation method. Results 73 protein peaks in the mass range 1800-16000Da were differentially expressed in tumour verses adjacent normal mucosa tissue (P ≤ 0.01, false discovery rate ≤ 0.05. Unsupervised hierarchical cluster analysis classified most tumour and normal mucosa into distinct cluster groups. Supervised prediction correctly classified the tumour/normal mucosa status of specimens in an independent test spectra dataset with 100% sensitivity and specificity (95% confidence interval: 67.9-99.2%. Supervised prediction using 'leave-one-out' cross validation algorithms for tumour spectra correctly classified 10/13 poorly differentiated and 16/18 well/moderately differentiated tumours (P = P = P = 0.001; ROC error, 0.212. Conclusions Protein expression profiling of surgically resected CRC tissue extracts by MALDI-TOF MS has potential value in studies aimed at improved molecular

Full Text Available Estudos com neuroimagem vêm replicando alguns achados relevantes ao entendimento de anormalidades neuroanatômicas, estruturais e funcionais associadas ao transtorno de estresse pós-traumático (TEPT. A dificuldade em sintetizar, categorizar e integrar a memória traumática em uma narrativa pode estar relacionada à relativa diminuição do volume e ativação do hipocampo, à diminuição na atividade do córtex pré-frontal, do cíngulo anterior e da área de Broca. O mecanismo deficiente de extinção da resposta ao medo e à desregulação emocional estão possivelmente relacionados à menor atividade cortical pré-frontal, implicado na atenuação do feedback negativo da atividade da amígdala. Tais memórias traumáticas não-hipocampo/pré-frontal dependentes são involuntariamente acessadas, apresentam-se fragmentadas sensorialmente, sem estrutura narrativa desenvolvida e tendem a permanecer com expressão emocional intensa e sensações vívidas. Processos psicoterapêuticos, baseados em exposição e reconstrução cognitiva, podem estimular as faculdades cognitivas e integrativas do encéfalo correspondentes às estruturas encontradas como deficitárias em indivíduos com TEPT. Nessa perspectiva, a memória poderá perder intensidade emocional, ser cognitivamente mais organizada e ainda, esvaecer-se com o tempo. Outras implicações dos achados da neuroimagem são discutidas no âmbito psicoterapêutico, assim como, as perspectivas de futuros estudos com neuroimagem no Brasil.Neuroimaging findings have been replicating some findings important to understanding structural and functional abnormalities associated with posttraumatic stress disorder (PTSD. The impairment in synthesizing, categorizing, and integrating a traumatic memory into a narrative may be related to a relative decrease in hippocampus volume and activation, and a decrease in activity of the prefrontal cortex, anterior cingulate, and Broca's area.

Primitive tribal groups (PTGs) are the most marginalised and vulnerable communities in India. Clinico-epidemiological studies on morbidity patterns among the elderly primitive tribe members are essential to recommend special intervention programmes to improve the health of the elderly in these communities. A community-based cross-sectional study was carried out among the elderly populations of four different PTGs, namely Langia Saora (LS), Paudi Bhuiyan (PB), Kutia Kondh (KK) and Dongria Kondh (DK) living in the forests of Orissa, India. Clinical and anthropometric data were collected using standard methods and haemoglobin was estimated by the cyanomethaemoglobin method. The average number of illnesses per person was 3.0. Common disabilities like vision and hearing impairment and mobility-related problems were found in considerable numbers. Gastrointestinal problems like acid peptic disease were found among 2.6% to 20% of cases. Non-specific fever was marked in 10.2% to 24.2% of individuals. The iodine deficiency disorder, namely goitre, was found among 4.2% to 6.0% of individuals. Diseases of the respiratory tract, like upper and lower respiratory tract infection, asthma, tuberculosis and leprosy, were found in small numbers. The prevalence of hypertension among males and females was 31.8% and 42.2%, respectively. The LS had the highest prevalence of hypertension (63% among men and 68% among women). With regard to anaemia status, severe anaemia was marked in 70% of males and 76.7% of females in the LS, while in other groups the prevalence of severe anaemia ranged from 15% to 33%. Although the prevalence of severe anaemia in other tribal communities is lower than in the LS, mild to moderate anaemia was found to range from 60% to 80%. The present study revealed a high prevalence of physical disabilities with both non-communicable as well as communicable diseases among the elderly primitive tribal members. This warrants the implementation of a special health care

Using genome-wide expression profiles of a prospective training cohort of breast cancer patients, ClinicoMolecular Triad Classification (CMTC) was recently developed to classify breast cancers into three clinically relevant groups to aid treatment decisions. CMTC was found to be both prognostic and predictive in a large external breast cancer cohort in that study. This study serves to validate the reproducibility of CMTC and its prognostic value using independent patient cohorts. An independent internal cohort (n = 284) and a new external cohort (n = 2,181) were used to validate the association of CMTC between clinicopathological factors, 12 known gene signatures, two molecular subtype classifiers, and 19 oncogenic signalling pathway activities, and to reproduce the abilities of CMTC to predict clinical outcomes of breast cancer. In addition, we also updated the outcome data of the original training cohort (n = 147). The original training cohort reached a statistically significant difference (p value of the triad classification was reproduced in the second independent internal cohort and the new external validation cohort. CMTC achieved even higher prognostic significance when all available patients were analyzed (n = 4,851). Oncogenic pathways Myc, E2F1, Ras and β-catenin were again implicated in the high-risk groups. Both prospective internal cohorts and the independent external cohorts reproduced the triad classification of CMTC and its prognostic significance. CMTC is an independent prognostic predictor, and it outperformed 12 other known prognostic gene signatures, molecular subtype classifications, and all other standard prognostic clinicopathological factors. Our results support further development of CMTC portfolio into a guide for personalized breast cancer treatments.

Full Text Available The term "cerebellar liponeurocytoma", recently adopted by the World Health Organization Working Group (WHO, replaced many other different terms used up to now to give name to this rare tumor. To our knowledge, less than 20 cases have been related up to now under different names like as "lipomatous medulloblastoma, lipidized medulloblastoma, neurolipocytoma, medullocytoma and lipomatous glioneurocytoma". The new nomenclature eliminates the word "medulloblastoma", reinforces its benign caracter, and includes it in the category of glioneuronal tumors. We describe an adictional case of this distinct clinico-pathological entity removed from the right cerebellar hemisphere of a 53-year-old woman. With the present case report, we hope to contribute to the knowledge on the diagnostic and prognostic implications derived from the finding of mature adipose-like tissue within a medulloblastomatous tumour.O termo "liponeurocitoma cerebelar" recentemente adotado pela Organização Mundial de Saúde (Classificação de Tumores Cerebrais - versão 2000, surgiu em substituição a vários outros utilizados até então, para denominar esta rara neoplasia. De nosso conhecimento há na literatura menos de 20 casos relatados sob termos diferentes tais como "meduloblastoma lipomatoso, meduloblastoma lipidizado, neurolipocitoma, medulocitoma e glioneurocitoma lipomatoso". A nova nomenclatura elimina a palavra "meduloblastoma", enfatiza seu caráter benigno e o coloca na categoria dos tumores glioneuronais. Descrevemos mais um caso desta rara entidade clínico-patológica, ressecada do hemisfério cerebelar direito em uma mulher de 53 anos. Com este caso esperamos contribuir para o melhor conhecimento sobre o diagnóstico, prognóstico e possibilidades terapêuticas advindas da presença de tecido adiposo em tumor meduloblastomatoso de adultos.

Full Text Available A síndrome de West é um tipo de espasmo infantil caracterizado por encefalopatia epiléptica associado a espasmos em flexão e deficiência mental de instalação no primeiro ano de vida e de etiologia incerta. Acredita-se ser determinada por diferentes fatores etiológicos como infeção intrauterina, esclerose tuberosa, asfixia perinatal ou afecções pós-natais. FORMA DE ESTUDO: Observacional coorte com corte transversal. MATERIAL E MÉTODO: No presente estudo dez pacientes com Síndrome de West foram submetidos ao exame de Potencial Evocado de Tronco Cerebral (BERA para avaliar o envolvimento do tronco cerebral e das vias auditivas a este nível. RESULTADO: Os achados anormais ao BERA incluem alteração na morfologia das curvas com reprodutibilidade apenas de onda I e II, (caso 7, aumento do intervalo interpico da onda I-V (casos 1, 2 e 9, aumento da proporção de amplitude da onda I/V (caso 8 e alteração do limiar eletrofisiológico (caso 7. Tais achados ao BERA sugerem que a disfunção do sistema nervoso resulte principalmente da hipogênese ou degeneração das células nervosas, em parte como resultado da dismielinização. CONCLUSÃO: Os autores recomendam o uso de estudos eletrofisiológicos para avaliar a disfunção do sistema nervoso central no paciente com suspeita de espasmo infantil.The West syndrome is a pediatric disease that involves muscular spasm, mental deficiency and epileptic encephalopathy. This disease tends to be noticed in the first year of life and has no etiology known.

Full Text Available La intención del presente trabajo es la de examinar qué tipo de apropiaciones y puesta en circulación realiza el arte, específicamente el teatro, de las diversas representaciones sociales del cuerpo. Nos detendremos en varios textos dramáticos del ciclo que ya lleva seis años de edición conocido en la Argentina como Teatro por la Identidad. Teatro por la Identidad es una propuesta estética surgida de la Asociación Abuelas de Plaza de Mayo con el fin de recuperar las identidades, aún no recobradas, de los hijos apropiados durante la dictadura militar de 1976. El teatro se presenta entonces como la alternativa estética y política privilegiada para inquietar e inquirir sobre las identidades de cada uno de los que asisten a las representaciones. El cuerpo adquiere un espacio de densa significación en esta propuesta teatral ya que la ficción hace presentes los cuerpos “desaparecidos” del pasado encarnándolos en los “cuerpos sin órganos”, corporeidades en grado cero de los “hijos” arrebatados, para restituirles la identidad perdida. El planteo teórico excede en mucho el trabajo sobre la noción de individualidad, ya que el cuerpo se presenta como medio de conocimiento histórico y social al articular cuerpo individual y cuerpo social en una lógica de implicancia necesaria.

Full Text Available Follicular red dots have been described as a trichoscopic feature of active discoid lupus erythematosus of the scalp and its presence associated with a better prognosis. We report five patients with pigmentary disorders in whom follicular red dots were detected during scalp examination. We suggest that this pattern is probably related to the rich vasculature that naturally envelops the normal hair follicle. The possible implications of such proposition in cases of discoid lupus erythematosus and other scalp disorders are also discussed.Pontos vermelhos foliculares foram descritos como achado tricoscópico de lupus eritematoso discóide do couro cabeludo em atividade e a presença destes associado a melhor prognóstico. Relatamos cinco pacientes com distúrbios da pigmentação nos quais pontos vermelhos foliculares foram detectados ao exame do couro cabeludo. Sugerimos que este padrão está provavelmente relacionado à rica vascularização que naturalmente envolve o folículo piloso normal. As possíveis implicações desta suposição nos casos de lupus eritematoso discóide e outras doenças do couro cabeludo também são discutidas.

Full Text Available Objetivo: Avaliar o quadro clínico, as anormalidades gestacionais e de parto e os resultados na cirurgia de estrabismo em pacientes com síndrome de Möbius. Métodos: Foram estudados, retrospectivamente, 7 pacientes com diagnóstico de síndrome de Möbius, dos quais 6 foram submetidos à cirurgia de estrabismo. Resultados: Além dos achados clássicos que caracterizam a síndrome, em todos os casos estudados observaram-se alterações gestacionais ou de parto. Em 2 pacientes encontrou-se no per-operatório, inserção posteriorizada do reto medial. Graças à fixação cruzada, esses pacientes geralmente não desenvolvem ambliopia. Conclusão: A cirurgia, quando indicada, deve constar apenas dos retrocessos musculares e acredita-se que o planejamento cirúrgico deva ser menor do que o feito em casos de paralisia isolada do nervo abducente de mesmo valor.Purpose: To evaluate clinical features, pregnancy and labour abnormalities and the results of strabismus surgery in patients with Möbius syndrome. Methods: The authors studied retrospectively 7 patients with Möbius syndrome, of whom 6 were submitted to strabismus surgery. Results: In addition to the classical findings that characterize the syndrome, pregnancy and labour insults were observed in all cases. In 2 patients a posterior medial rectus insertion was found during surgery. Due to cross-fixation, these patients usually do not develop amblyopia. Conclusions: Surgery should consist of muscle recessions, but recessing them less than it would be done for similar isolated abducens palsy.

In this work we did a sectional study of 31 asthmatic patients with several levels of disease severity, which were submitted to high resolution computed tomography of the thorax and spirometry, between the months of July, 1995 and August, 1997. The tomographic findings were correlated with the clinical classification of the patients and the most frequent tomographic findings were bronchial wall thickening, bronchial dilatation, air trapping, centrilobular opacities, cicatricial linear shadows, mucoid impaction, emphysema and atelectasis. In asthmatic patients of long duration we observed small airway disease and irreversible lesions as the predominant findings. In smoking patients there was no high frequency of emphysema. (author)

Full Text Available Background and Objective: Dengue, an acute viral disease, transmitted by Aedes mosquitoes, has a variable clinical spectrum ranging from asymptomatic infection to life-threatening dengue hemorrhagic fever and dengue shock syndrome. However, neurological complications, in general, are unusual but have been observed more frequently in the recent past, and some studies highlighted varied neurological complications during the course of illness. Although dengue is classically considered a nonneurotropic virus, there is increasing evidence for dengue viral neurotropism. In this study, we have evaluated clinico-radiological profile and outcome of nine serologically confirmed dengue patients having varied manifestations of central nervous system (CNS involvement. Materials and Methods: All the consecutive patients presented with neurological complications with positive serology for dengue infection (IgM positivity in Department of Medicine, in a tertiary care hospital in Eastern India from August 2013 to October 2014 were included in the study. These patients were subjected to a detailed clinical evaluation, laboratory assessment including complete hemogram, coagulation profile, liver function test, serum electrolytes, and routine CSF (Cerebrospinal Fluid study with the exclusion of other common neuroinvasive pathogens. Results: Out of 9 patients with neurological complications associated with confirmed dengue infection, 2 (22% patients had dengue encephalopathy, 5 (56% patients have dengue encephalitis, 1 (11% patient had dengue meningitis, and 1 (11% patient had postdengue immune-mediated CNS involvement. Conclusion: This case series reaffirms the occurrence of varied CNS manifestations in dengue virus infection and underlines the importance of inclusion of dengue in the differential diagnosis of acute encephalitis syndrome.

Studies of several tumour types have shown that expression profiling of cellular protein extracted from surgical tissue specimens by direct mass spectrometry analysis can accurately discriminate tumour from normal tissue and in some cases can sub-classify disease. We have evaluated the potential value of this approach to classify various clinico-pathological features in colorectal cancer by employing matrix-assisted laser desorption ionisation time of-flight-mass spectrometry (MALDI-TOF MS). Protein extracts from 31 tumour and 33 normal mucosa specimens were purified, subjected to MALDI-Tof MS and then analysed using the 'GenePattern' suite of computational tools (Broad Institute, MIT, USA). Comparative Gene Marker Selection with either a t-test or a signal-to-noise ratio (SNR) test statistic was used to identify and rank differentially expressed marker peaks. The k-nearest neighbours algorithm was used to build classification models either using separate training and test datasets or else by using an iterative, 'leave-one-out' cross-validation method. 73 protein peaks in the mass range 1800-16000Da were differentially expressed in tumour verses adjacent normal mucosa tissue (P ≤ 0.01, false discovery rate ≤ 0.05). Unsupervised hierarchical cluster analysis classified most tumour and normal mucosa into distinct cluster groups. Supervised prediction correctly classified the tumour/normal mucosa status of specimens in an independent test spectra dataset with 100% sensitivity and specificity (95% confidence interval: 67.9-99.2%). Supervised prediction using 'leave-one-out' cross validation algorithms for tumour spectra correctly classified 10/13 poorly differentiated and 16/18 well/moderately differentiated tumours (P = < 0.001; receiver-operator characteristics - ROC - error, 0.171); disease recurrence was correctly predicted in 5/6 cases and disease-free survival (median follow-up time, 25 months) was correctly predicted in 22

La variedad esclerosis nodular es la más frecuente, afecta generalmente regiones supradiafragmáticas y se divide en 2 grados, con características morfológicas y pronósticas diferentes. El grado II, de mal pronóstico, exige formas de tratamiento más agresivas. La celularidad mixta suele tener mayor diseminación de la enfermedad y junto a la esclerosis nodular, se catalogan como formas clásicas de la enfermedad, con positividad para los marcadores inmunofenotípicos CD15 y CD30. El predominio linfocítico se considera un linfoma de células del centro germinal y emerge como entidad clínicopatológica diferente. La depleción linfocítica se diagnostica con baja frecuencia y tiene un pronóstico desfavorable.

Full Text Available INTRODUCTION: The Apert syndrome is a rare disorder of autosomal dominant inheritance caused by mutations in the FGFR2 gene at locus 10q26; patients with this syndrome present severe syndactyly, exophthalmia, ocular hypertelorism and hypoplastic midface with Class III malocclusion, besides systemic alterations. Most investigations available on the Apert syndrome address the genetic aspect or surgical management, with little emphasis on the oral aspects. OBJECTIVE: to investigate the oral findings, including dental anomalies, ectopic eruption of the maxillary permanent first molars and soft tissue alterations, in subjects with Apert syndrome. MATERIALS AND METHODS: clinical and radiographic examination of nine patients with Apert syndrome, aged 6 to 15 years, not previously submitted to orthodontic or orthognathic treatment. RESULTS: dental anomalies were present in all patients, with one to eight anomalies per individual. The most frequent anomalies were tooth agenesis, mainly affecting maxillary canines, and enamel opacities (44.4% for both. Ectopic eruption of maxillary first molars was found in 33.3% of patients; lateral palatal swellings were observed in 88.8% of patients. CONCLUSIONS: The occurrence of typical lateral palatal swellings agrees with the literature. The high prevalence of dental anomalies and ectopic eruption may suggest a possible etiologic relationship with the syndrome.INTRODUÇÃO: A síndrome de Apert é um distúrbio raro de herança autossômica dominante causado por mutações no lócus 10q26 do gene FGFR2; pacientes com esta síndrome apresentam sindactilia severa, exoftalmia, hiperteleorbitismo e hipoplasia da face média com má oclusão de Classe III, além de alterações sistêmicas. A maior parte dos estudos disponíveis sobre a síndrome de Apert aborda o aspecto genético ou manejo cirúrgico, com pouca ênfase nos aspectos bucais.

MÉTODOS: Participaram deste estudo 20 escolares, sendo dez com diagnóstico interdisciplinar de dislexia do desenvolvimento e dez com bom desempenho acadêmico, submetidos a avaliações audiológica, do processamento auditivo e de consciência fonológica. Os escolares com dislexia do desenvolvimento foram submetidos a exame de imagem (SPECT. RESULTADOS: Os resultados indicaram diferença estatisticamente significante entre as habilidades auditivas de sequência para sons verbais, mensagem competitiva ipsi e contralateral, dicótico de dígitos e dissílabos alternados e habilidades de síntese, segmentação, manipulação e transposição fonêmica. Entre os escolares com dislexia do desenvolvimento, evidenciou-se hipoperfusão da porção mesial do lobo temporal. CONCLUSÃO: Os achados deste estudo evidenciaram correlação entre provas de memória auditiva e manipulação silábica e fonêmica e associação entre habilidades auditivas e fonológicas, sugerindo que os processos auditivos interferem diretamente na percepção de aspectos acústicos, temporais e sequenciais dos sons para formação de uma representação fonológica estável, e que isto pode ser decorrente da presença de alterações de fluxo sanguíneo no lobo temporal.PURPOSE: To correlate auditory and metaphonological abilities and neuroimaging in students with developmental dyslexia, and to compare these findings to those obtained with students with good academic performance. METHODS: Twenty children participated in this study: ten with an interdisciplinary diagnostic of developmental dyslexia, and ten students with good academic performance.

Full Text Available Resumo: A broncofibroscopia possui um papel no diagnóstico e terapêutica das lesões iniciais do sistema respiratório, secundárias a queimaduras e inalação de fumo. Poucos trabalhos têm descrito as lesões da árvore brônquica encontradas na fase tardia pós-inalação.Os autores deste artigo investigaram as alterações histopatológicas da traqueia e brônquios na fase inicial e tardia pós-inalação. Cinco doentes sobreviventes a queimaduras e lesão da árvore brônquica por inalação foram avaliados, numa fase inicial e tardia através de broncofibroscopia, com realização de biópsias da mucosa. Numa fase tardia e apesar de a mucosa traqueobrônquica se apresentar praticamente recuperada macroscopicamente, persiste a nível histológico a invasão por células inflamatórias e dilatação dos capilares na região subepitelial. Nos casos de lesão por inalação com queimadura grave, o edema pulmonar e brônquico tornam-se mais prolongados, assim como o aumento das secreções brônquicas.Nalguns doentes, a produção exagerada e contínua de secreções brônquicas ocasiona quadros de obstrução e atelectasia. Os autores referem ainda que os achados broncoscópicos e histológicos encontrados na fase de cicatrização podem possuir um papel preditivo a longo prazo na função pulmonar dos doentes sobreviventes. Consideram ainda que a limpeza agressiva da árvore brônquica, com remoção de partículas estranhas inaladas e das secreções, é útil na redução da resposta inflamatória e obstrutiva pós lesão inalatória.

Full Text Available RESUMO O presente trabalho é um relato de caso que descreve os achados fonoaudiológicos e de qualidade de vida apresentados por uma adolescente com um tumor do sistema nervoso central acometida pela mielinólise extrapontina. A mielinólise extrapontina é uma doença desmielinizante aguda que pode ser causada por variações abruptas na osmolaridade sérica, como o que ocorre na rápida correção da hiponatremia. Os dados foram obtidos a partir da avaliação clínica fonoaudiológica, de questionários pediátricos sobre a qualidade de vida e dados contidos no prontuário médico. A paciente apresentou mutismo, disartria e disfagia decorrentes da mielinólise extrapontina, com impactos significativos na sua comunicação verbal, alimentação e qualidade de vida. Os escores de qualidade de vida após a mielinólise extrapontina apresentaram piora quando comparados aos do período anterior à doença. Recebeu atendimento fonoaudiológico hospitalar e ambulatorial. Foram observadas evoluções nos padrões de fala, deglutição e mobilidade das estruturas orofaciais, com reversão parcial dos déficits neurológicos. A atuação fonoaudiológica, como parte de uma equipe multiprofissional de saúde, é de grande importância na reabilitação funcional dos pacientes acometidos por esta doença.

Full Text Available Introdução: Manifestações laríngeas do refluxo gastro-esofágico são problemas cada vez mais comuns. Estudos revelam alta associação com sensação de "globus", rouquidão crônica e com tosse crônica. Seu diagnóstico e tratamento diferem da clássica doença do refluxo gastro-esofágico. Os achados à endoscopia laríngea de hiperemia e edema de estruturas glóticas, espessamento do espaço interaritenóideo, granulomas, pólipos, edema de Reinke, estenose subglótica sugerem uma investigação diagnóstica completa através da pHmanometria de 24 horas, exame de maior sensibilidade e especificidade. Objetivo: correlacionar achados clínicos e laringoscópicos precoces sugestivos de refluxo gastro-esofágico com resultados da pHmanometria de 24 horas. Avaliar terapia medicamentosa e modificações dietéticas. Forma de estudo: Clínico prospectivo. Material e Método: pacientes adultos com queixas crônicas: tosse seca, "globus", sialorréia, disfonia, pigarro, halitose e engasgos. Foram excluídos pacientes com outras patologias de vias aéreas. Endoscopia laríngea descartava aqueles que apresentassem lesões laríngeas mais avançadas. Encaminhamento à pHmanometria e iniciado tratamento clínico.

Background: The P hiladelphia Negative Classic Myeloproliferative Neoplasms include polycythaemia vera (PV), essential thrombocythaemia (ET) and idiopathic myelofibrosis (IMF). These three disorders share several clinical and laboratory features including JAK2 V617F mutation. Our objectives were to determine the clinico-pathological profile and outcomes of Pakistani patients with polycythaemia vera (PV), essential thrombocythaemia (ET) and idiopathic myelofibrosis (IMF) in order to have an insight regarding behaviour of these conditions. Methods: A retrospective analysis of all the cases of PV, ET and IMF diagnosed at our institute from January 1995 to December 2013 was performed. Age, gender, clinical presentation, laboratory investigations, treatment provided and duration of follow-up were included for analysis. Appropriate statistics were utilized for calculation of data. Results: A total of 58 patients were diagnosed as PV, ET or IMF during the study period. Male to female ratio was 1.1:1. Forty five percent (n=27) patients came to medical attention due to abnormal laboratory results, 3 had cerebrovascular events, 3 had pruritus, and 1 patient each with gangrene and Budd-Chiari syndrome. Haemorrhage was not seen in any patient. Sixty percent (n=35) patients were treated with phlebotomy, hydroxyurea and aspirin alone or in combination. None of the patients transformed to myelofibrosis (MF) or myelodysplasia (MDS) during the mean (±SD) follow-up period of 57.2±50 months. One patient with ET transformed to acute myeloid leukaemia 9 years after the diagnosis. Conclusions: This study demonstrated a relatively more benign form of PV, ET and IMF with lesser frequency of symptoms, good response to treatment and less likelihood of transformation to MF, MDS or AML.

Full Text Available Invasive micropapillary carcinoma (IMPC of the breast is a rare subtype of breast cancer that is associated with a high incidence of regional lymph node metastases and a poor clinical outcome. However, the clinico-pathological features and prognostic factors of IMPC are not well understood.A total of 188 IMPC cases and 1,289 invasive ductal carcinoma (IDC cases were included. The clinical features, breast cancer-specific survival (BCSS and recurrence/metastasis-free survival (RFS of the patients were compared between these two groups.The IMPC patients exhibited more features of aggressive carcinoma than the IDC patients, including larger tumor size, higher tumor stage, a greater proportion of nodal involvement and an increased incidence of lymphovascular invasion. Patients with IMPC had lower 5-year BCSS and RFS rates (75.9% and 67.1%, respectively than patients with IDC (89.5% and 84.5%, respectively. Compared to IDC patients, the patients with IMPC had a significantly higher percentage of stage III breast cancer (51.3% versus 21.7%. In a stage-matched Kaplan-Meier analysis, the patients with stage III IMPC had lower 5-year BCSS and RFS rates than patients with stage III IDC (BCSS, P = 0.004; RFS, P = 0.034. A multivariate analysis revealed that TNM stage was an independent prognostic factor for patients with IMPC. The proportion of cancers with a luminal-like subtype was significantly higher in IMPC than in IDC (P<0.001. However, after matching by molecular subtype, the patients with IMPC had significantly worse clinical outcomes than patients with IDC.In Chinese women, IMPCs displayed more aggressive behaviors than IDCs, resulting in poorer clinical outcomes for patients with IMPC, regardless of a favorable molecular subtype. Our findings illustrate that the poorer survival of patients with IMPC might be due to an increased incidence and aggressiveness of tumors in TNM stage III.

Our aim was to describe MRI findings inpatients with schistosomal liver disease identified by US. METHODS: Fifty-four patients (mean age 41.6±13.5years from an area endemic for Schistosomiasis mansoni were selected for this study.All had US indicating liver schistosomal fibrosis and were evaluated with MRI performed witha 1.5-T superconducting magnet unit (Sigma. RESULTS: Forty-seven (87% of the 54 patientsshowing signs of periportal fibrosis identified through US investigation had confirmed diagnosesby MRI. In the seven discordant cases (13%, MRI revealed fat tissue filling in the hilar periportalspace where US indicated isolated thickening around the main portal vein at its point of entryto the liver. We named this the fatty hilum sign. One of the 47 patients with MRI evidence ofperiportal fibrosis had had his gallbladder removed previously. Thirty-five (76.1% of the other46 patients had an expanded gallbladder fossa filled with fat tissue, whereas MRI of the remainingeleven showed pericholecystic signs of fibrosis. CONCLUSIONS: Echogenic thickening of thegallbladder wall and of the main portal vein wall heretofore attributed to fibrosis were frequentlyidentified as fat tissue in MRI. However, the gallbladder wall thickening shown in US (expandedgallbladder fossa in MRI is probably secondary to combined hepatic morphologic changes inschistosomiasis, representing severe liver involvement.INTRODUÇÃO: Não existem estudos que correlacionam os achados da ressonância magnética (RM aos da ultrassonografia (US em pacientes com esquistossomose mansônica.

Usam para isto um critério clínico, outro morfológico, em uma revisão de 372 pneumopatias infecciosas em casos de autópsias. Caracterizaram morfologicamente a resposta à agressão viral pela presença de: infiltrado mononuclear intersticial, predominantemente peribronquilar; alterações degenerativas ou mesmo necrose e hiperplasia do epitélio respiratório; membrana hialina; descamação epitelial; células gigantes sinciciais alveolares e bronquiolares; inclusões nucleares e citoplasmáticas; edema proteináceo alveolar e septal, proliferação intersticial conjuntiva incipiente. Criticam o erro por excesso de diagnósticos de "pneumonia mononuclear intesticial" e o erro por falta quando o acometimento bacteriano dificulta o diagnóstico de lesão atribuível a vírus. Além disso realçam a importância de achado de bonquiolite aguda como fundamental para o diagnóstico.

Full Text Available Abstract Background Human cutaneous anthrax results from skin exposure to B. anthracis, primarily due to occupational exposure. Bangladesh has experienced a number of outbreaks of cutaneous anthrax in recent years. The last episode occurred from April to August, 2011 and created mass havoc due to its dreadful clinical outcome and socio-cultural consequences. We report here the clinico-demographic profile and treatment outcome of 15 cutaneous anthrax cases attended at the Dermatology Outpatient Department of Rajshahi Medical College Hospital, Bangladesh between April and August, 2011 with an aim to create awareness for early case detection and management. Findings Anthrax was suspected primarily based on cutaneous manifestations of typical non-tender ulcer with black eschar, with or without oedema, and a history of butchering, or dressing/washing of cattle/goat or their meat. Diagnosis was established by demonstration of large gram-positive rods, typically resembling B. anthracis under light microscope where possible and also by ascertaining therapeutic success. The mean age of cases was 21.4 years (ranging from 3 to 46 years, 7 (46.7% being males and 8 (53.3% females. The majority of cases were from lower middle socioeconomic status. Types of exposures included butchering (20%, contact with raw meat (46.7%, and live animals (33.3%. Malignant pustule was present in upper extremity, both extremities, face, and trunk at frequencies of 11 (73.3%, 2 (13.3%, 1 (6.7% and 1 (6.7% respectively. Eight (53.3% patients presented with fever, 7 (46.7% had localized oedema and 5 (33.3% had regional lymphadenopathy. Anthrax was confirmed in 13 (86.7% cases by demonstration of gram-positive rods. All cases were cured with 2 months oral ciprofloxacin combined with flucoxacillin for 2 weeks. Conclusions We present the findings from this series of cases to reinforce the criteria for clinical diagnosis and to urge prompt therapeutic measures to treat

Introduction: the study of biological subtype of breast cancer (B C) given by the expression tumor estrogen receptors (E R), progesterone (P R) and growth factor receptor and evolutionary. Objective: To know the profile of tumor expression of HER2, ER and P R and their relation with to characteristics clinico pathological characteristics in Uruguayan and Argentine patients with breast cancer. Material and Methods: The medical records of patients who underwent analyzed C M I-III invasive stages between 03/2006 and 03/2008 and assisted in Oncology Services where the authors are performing, which had selected determination ER, P R and HER2 by immunohistochemistry. The expression profile of these was markers compared with age at diagnosis, type and histological grade (GH) and pathological stage (TNM). Results: 291 patients (197 Uruguayan and 94 Argentine) were included whose characteristics were: mean age: 56 years, ductal carcinoma: 85%, GH 1-2: 55% stage I-II: 70%, metastasis axillary: 51%, ER / P R +: 78% HER2 + 12%. Three subtypes were defined: HER2 ER / P R + (71%), HER2 + (12% Uruguayan patients: 10%, Argentine patients: 17%) and negative Triple (TN) (17%). The joint analysis of the patients in both countries showed that subtypes TN and HER2 is associated with greater histological grade (p <0.05). Furthermore, in the group of patients Uruguayan, TN subtype was associated with younger age at diagnosis (p <0.05) subtype HER2, ER / PR +. Conclusions: The percentage of patients with CM Uruguayan invasive HER2 + subtype (10%) is smaller than that reported by other studies (17-28%) and that observed in our study Argentine group of patients. Consistent with previous studies, TN subtypes and HER2 + correlated with more undifferentiated tumors and in the group of Uruguayan patients TN appeared in younger patients

Abstract Background In Slovenia like in other countries, till recently, personal history of epithelial ovarian cancer (EOC) has not been included among indications for genetic counselling. Recent studies reported up to 17% rate of germinal BRCA1/2 mutation (gBRCA1/2m) within the age group under 50 years at diagnosis. The original aim of this study was to invite to the genetic counselling still living patients with EOC under 45 years, to offer gBRCA1/2m testing and to perform analysis of gBRCA1/2m rate and of clinico-pathologic characteristics. Later, we added also the data of previously genetically tested patients with EOC aged 45 to 49 years. Patients and methods All clinical data have to be interpreted in the light of many changes happened in the field of EOC just in the last few years: new hystology stage classification (FIGO), new hystology types and differentiation grades classification, new therapeutic possibilities (PARP inhibitors available, also in Slovenia) and new guidelines for genetic counselling of EOC patients (National Comprehensive Cancer Network, NCCN), together with next-generation sequencing possibilities. Results Compliance rate at the invitation was 43.1%. In the group of 27 invited or previously tested patients with EOC diagnosed before the age of 45 years, five gBRCA1/2 mutations were found. The gBRCA1/2m detection rate within the group was 18.5%. There were 4 gBRCA1 and 1 gBRCA2 mutations detected. In the extended group of 42 tested patients with EOC diagnosed before the age of 50 years, 14 gBRCA1/2 mutations were found. The gBRCA1/2m detection rate within this extended, partially selected group was 33.3%. There were 11 gBRCA1 and 3 gBRCA2 mutations detected. Conclusions The rate of gBRCA1/2 mutation in tested unselected EOC patients under the age of 50 years was higher than 10%, namely 18.5%. Considering also a direct therapeuthic benefit of PARP inhibitors for BRCA positive patients, there is a double reason to offer genetic testing to

The development of neuroimaging has allowed clinicians to improve clinico-anatomic correlations in patients with strokes. Brainstem and cerebellum structures are well delineated on MRI, but there is a lack of standardization in their arterial supply. We present a system of 12 brainstem and cerebellum axial sections, depicting the dominant arterial territories and the most important anatomic structures. These sections may be used as a practical tool to determine arterial territories on MRI, and may help establish consistent clinico-anatomic correlations in patients with brainstem and cerebellar ischemic strokes.

Full Text Available OBJECTIVE: To present the case of a 54-year-old man with loss of speech, but with preservation of voluntary facio-lingual motility, language and other cognitive abilities (Broca's aphemia. METHOD: Observation of patient oral communicative abilities and general behavior, neuropsychological assessment and cranial computed tomography. RESULTS: Computed tomography showed a hyperdense lesion in the subcortex of the left precentral gyrus corresponding to Brodmann's area 6 and 44. Neuropsychological assessment confirmed that the major cognitive domains were intact. CONCLUSION: Our patient reiterates the validity of Broca's aphemia as a clinico-anatomic entity allowing us to portray it for the first time in pictures. From a neurobehavioral perspective, aphemia is related to apraxia rather than to aphasia, a fact that may have hampered the full grasp of its far-reaching implications for neurology and aphasiology.OBJETIVO: Apresentar o caso de um paciente de 54 anos de idade com perda da fala, mas preservação da linguagem, das demais capacidades cognitivas, e da motilidade fácio-lingual voluntária (afemia de Broca. MÉTODO: Observação da capacidade de comunicação oral e do comportamento geral, exame neuropsicológico e tomografia computadorizada do crânio. RESULTADOS: A tomografia computadorizada revelou lesão hiperdensa no subcórtex do giro precentral esquerdo correspondendo às áreas 6 e 44 de Brodmann. O exame neuropsicológico confirmou que os principais domínios cognitivos se encontravam intactos. CONCLUSÃO: Nosso paciente reiterou a validade da afemia de Broca como entidade anátomo-clínico permitindo documentá-la em fotos pela primeira vez. Da perspectiva neurocomportamental, a afemia está vinculada às apraxias e não às afasias, o que pode ter prejudicado a apreensão plena do seu profundo significado para a neurologia e para a afasiologia.

Full Text Available BACKGROUND Under nutrition is one of the major problems in the field of Paediatrics. The greatest risk of malnutrition is in the first two years of life. The effects of this early damage on health, brain development, intelligence, educability and productivity are potentially reversible. The current study was an attempt to find out the clinico epidemiological profile, evaluate them for trace elements deficiency and most appropriate management options in those who are admitted with infantile tremor syndrome. MATERIALS AND METHODS The current study was a hospital based cross sectional study that was conducted in the Department of Paediatrics, Dr. S. N. Medical College Jodhpur. Duration of study was One Year. Any child up to the age of three years of age admitted in the paediatric wards with typical features of infantile tremor syndrome. RESULTS Maximum numbers of patients were found between 6 months to 12 months of age, there was slight male predominance. The majority of infants in our study (85% were exclusively breast fed, 66% of cases were having low serum Copper level. 9% of cases were having low serum zinc level. 8% of cases were having low serum copper level with tremors. CONCLUSION In our study the fact that NTS is mainly seen in children who are exclusively breast feed for a longer period with delayed introduction of weaning foods. The main presenting features remain developmental delay, hyper pigmentation and anemia. Among nutritional factors, deficiency of copper and zinc in children plays a big role in development of disease. Thus to prevent the development of nutritional tremor syndrome stress should be on early timely introduction of weaning foods, especially rich in copper and zinc. What is already known about this Study- low levels of trace elements like copper and zinc may be responsible for typical clinical manifestations in patients of infantile tremor syndrome. Pronged and Exclusive breast feeding further aggravate these features

Magnetic resonance (MR findings, associated with clinical data and electroencephalogram (EEG, may indicate the diagnosis and could be an indicative of prognosis. We studied 5 patients with Rasmussen's encephalitis, assessing clinical history and MR images. All patients had refractory focal seizures with a predominant motor component associated with hemispheric atrophy, that was proportional to severity of disease and neurological deficits in these patients. Gray and white matter abnormal signal on T2 MR images were found in patients who had hemiparesis. It was not related to the duration of the disease but to aggressiveness. MR proton spectroscopy in severe disease showed lactate and choline increase and decreased NAA, reflecting neuronal and axonal loss, gliosis and elevated membrane turnover and recent - crisis (not controlled. MR studies, in addition to help in diagnosis, may be useful for monitoring metabolic changes and progression of disease in Rasmussen's encephalitis.A encefalite de Rasmussen é uma devastadora síndrome com disfunção cerebral multifocal e convulsões focais.

Clinico-roentgenological changes in dynamics are studied in 72 children and adolescents with a limited hematogenous vertebrae body osteomyelitis. The clinico-roentgenologic examination lasted from 1 to 15 years. Such a durable examination permitted to trace the development, regularities and remote results of the disease. The increase in vertebrae body height (lengthening) which is considered a pathognomonic sign of tuberculous spondylitis is described for the first time. Unlike tuberculosis, hematogenous spondylitis brings about the body lengthening of both ajacent nonaffected and affected vertebrae in the case of their surface or limited focal injury. 12 refs.; 1 fig

Questi fattori sono stati responsabili anche di un impoverimento genetico della forma autoctona italiana Sus scrofa meridionalis e majori che sembrano persistere solo in Sardegna e Maremma (Apollonio et al., 1988. Tra le riserve in cui si ritiene possano trovarsi popolazioni ancora integre, figura la tenuta presidenziale di Castelporziano (Roma. Prendendo spunto da questo lavoro, con il nostro contributo riportiamo i risultati, a livello genetico, della ibridazione con il maiale da parte di cinghiali della Campania, basato sul DNA microsatellite di 4 loci polimorfi. Sono state studiate 9 popolazioni (allevate e libere, usando per riferimenti maiali allo stato brado e cinghiali di Castelporziano. Dall?analisi delle frequenze alleliche è stato eseguito il test di assignment (implementato in una sub routine del software Arlequin 2.0 che individua la possibile origine di un individuo, rispetto ad una rosa di probabili popolazioni di riferimento (Paetkau et al., 1998. Con i risultati del test di assignment si è costruito il grafico log-log genotype, rappresentato da un piano individuato dalle due variabili di riferimento (cinghiale e maiale brado. Le popolazioni esaminate evidenziano una generalizzata distribuzione a cavallo tra i due riferimenti con individui geneticamente simili al cinghiale ed altri al maiale.

Full Text Available A 64-year-old apparently immunocompetent white man developed lung and brain lesions of disseminated cryptococcosis. The radiologic features mimicked those of lung cancer metastatic to the central nervous system. C. gattii was recovered from cultures of bronchoalveolar lavage fluid, brain biopsy, and blood. The same fungus was recovered from pulmonary and brain specimens at autopsy. Serum and cerebrospinal fluid cryptococcal antigen tests were diagnostic in our case and should be included in the diagnostic evaluation of unexplained pulmonary and cerebral lesions. A literature search showed few reports of fungemia by this species of Cryptococcus, contrasting to C. neoformans.Homem branco de 64 anos, aparentemente imunocompetente, desenvolveu lesões pulmonares e cerebrais por criptococose disseminada. Os achados radiológicos foram similares àqueles encontrados em pacientes com câncer de pulmão e metástase no sistema nervoso central. C. gattii foi isolado de cultivos de lavado broncoalveolar, biópsia cerebral e sangue. O mesmo fungo foi encontrado em fragmentos pulmonares e cerebrais obtidos da autópsia. Testes de antígeno no soro e no líquido cefalorraquidiano foram diagnóstico no nosso caso e devem ser incluídos na avaliação diagnóstica de lesões pulmonares e cerebrais indefinidas. Pesquisa na literatura mostrou poucos relatos de fungemia por esta espécie de Cryptococcus, contrastando com C. neoformans.

Kaposis sarcoma (KS) is in angio proliferative disorder associated with human herpes virus 8 infection. Classic Ks is the most prevalent type of KS in countries of the Mediterranean basin including Egypt. Several in vitro studies have detected C-kit expression in AIDS related-KS however, only a few studies addressed this Issue In the classic type with no data on the ethnicity of studied cases. The prospect of installing targeted anti-c-kit treatment to KS patients presents a promising avenue in KS therapeutics. Aim: To elucidate the expression of c-kit in classic KS cases and study possible relations with expression of HHV8 latency-associated nuclear antigen-1 (LANA-1) and other clinico pathological parameters. Methods: Twenty four cases of classic KS of the plaque and nodular stages in the lower limb were studied. Immunohistochemical detection of HHV8-LANA-1 and c-kit was carried out on archival paraffin embedded tissue, possession of the pathology and dermatology Departments, Alexandria School Of Medicine, Egypt. Statistical analysis of possible reltions between both antigen and clinico pathological parameters (patient age and gender and histological stage) was performed. Results: HHV8 expression was detected in 100% of cases while c-kit immunoreactivity was found in 54.2% of cases. There was no correlation between c-kit and HHV8 immunoreactivity or any of the studied clinico pathological parameters. Conclusions: This is the first report of c-kit expression in classic KS in an ethnically homogeneous cohort of arabs of the Mediterranean region. We detected c-kit expression in about half the cases with no relationship to HHV8 LANA expression or clinico pathological parameters

Full Text Available OBJETIVO: Comparar a definição de síndrome do desconforto respiratório agudo (SDRA estabelecida pela American-European Consensus Conference (AECC, Conferência Americano-Européia com achados de necropsia. MÉTODOS: Avaliaram-se todos os pacientes que morreram na unidade de terapia intensiva do Hospital Universitário da Universidade Federal de Juiz de Fora entre 1995 e 2003 e que foram submetidos à necropsia. Seus prontuários foram revisados para estabelecer a presença ou não dos critérios clínicos de SDRA, cujo diagnóstico histológico foi definido pela presença de dano alveolar difuso (DAD. RESULTADOS: No período, 592 pacientes faleceram e 22 foram submetidos à necropsia. Destes, 10 pacientes (45% preencheram os critérios de SDRA pela AECC e sete (32% preencheram os critérios histopatológicos de DAD. A sensibilidade da definição clínica foi de 71% (IC95%: 36-92% e a especificidade foi de 67% (IC95%: 42-85%.

Gastric cancer peritoneal carcinomatosis is a common clinical problem, but there are no suitable large animal models to study this problem. This study was to establish a stable rabbit peritoneal carcinomatosis model of gastric cancer using VX2 tumor, and analyze the clinico-pathological features. VX2 tumor was implanted into 36 New Zealand rabbits by 3 methods: laparotomic orthotopic injection of cancer cells into the submucosal layer of the stomach (Group A), laparotomic implantation of tumor tissue into the greater omentum immediately beneath the gastric antrum (Group B), and percutaneous injection of tumor cells directly into the peritoneal cavity (Group C), 12 rabbits in each group. The animals were closely observed and detailed clinico-pathological studies were conducted. The success rates of peritoneal carcinomatosis formation were 100% (12/12), 91.7% (11/12) and 58.3% (7/12), respectively, for Groups A, B and C (P = 0.019, A versus C; P = 0.077, B versus C; P = 0.500, A versus B, Fisher's exact test). Two weeks after submucosal cancer cells injection in Group A, ulcerative gastric cancer with peritoneal carcinomatosis showed typical VX2 tumor pathology, with widespread intraperitoneal metastatic nodules, bloody ascites and perspicuous pulmonary metastases. The clinico-pathological progression pattern was very similar to patients of advanced gastric cancer with peritoneal carcinomatosis. Groups B and C showed similar pattern of cancer progression, but less aggressive. First large animal model of peritoneal carcinomatosis from gastric cancer has been established by laparotomic orthotopic injection of VX2 cancer cells into the submucosal layer of the stomach, providing a more suitable model for surgical interventional studies. The clinico-pathological features of this model resemble human peritoneal carcinomatosis

Full Text Available Persistência hiperplásica do vítreo primitivo (PHVP é um desenvolvimento anormal, afetando crianças, resultante da falha de regressão do vítreo primitivo e dos vasos hialóides, com proliferação de tecido conectivo. A PHVP pode ter três variações: uma anterior, outra posterior e uma terceira com a combinação das duas. Clinicamente manifesta-se como leucocoria (reflexo branco pupilar em um olho de dimensões reduzidas. Esta anomalia é usualmente unilateral e não associada com outros achados sistêmicos. Leucocoria, descolamento de retina, pregas retinianas e catarata podem confundir PHVP com outras afecções oculares que têm achados semelhantes. Retinoblastoma, catarata congênita, retinopatia da prematuridade e pseudogliomas são doenças com achados semelhantes aos da PHVP. A visualização direta dos remanescentes do sistema vascular hialóide fetal é a melhor evidência da lesão presente, se não fosse, muitas vezes impossivel, à fundoscopia, devido à opacidade do tecido. Nestes casos, a visualização indireta, por meio de ultra-sonografia, tomografia computadorizada e ressonância magnética, fornece o diagnóstico. As imagens obtidas por estes métodos proporcionam, ainda, informações e diagnóstico diferencial com outras doenças, particularmente com o retinoblastoma. Os autores fazem uma revisão na literatura e apresentam um estudo iconográfico das imagens e achados da PHVP.

Magnetotherapy and laser therapy were used in complex and complex-combined regimens in 75 patients after cerebral ischemic or hemorrhagic stroke starting on the poststroke week 4-5. Clinico-neurologic, neurophysiological and cerebrohemodynamic findings evidence for the highest effectiveness of neurorehabilitation including complex magneto-laser therapy in hemispheric ischemic and hemorrhagic stroke of subcortical location in the absence of marked clinico-tomographic signs of dyscirculatory encephalopathy. Complex-combined magneto-laser therapy is more effective for correction of spastic dystonia. Mutual potentiation of magnetotherapy and laser therapy results in maximal development of collateral circulation and cerebral hemodynamic reserve (84% of the patients). Complex effects manifest in arteriodilating and venotonic effects. Complex magneto-laser therapy is accompanied by reduction of hyperthrombocythemia and hyperfibrinogenemia.

Full Text Available Alzheimer's disease (AD and related dementias are a major public health challenge and present a therapeutic imperative for which we need additional insight into molecular pathogenesis. We performed a genome-wide association study and analysis of known genetic risk loci for AD dementia using neuropathologic data from 4,914 brain autopsies. Neuropathologic data were used to define clinico-pathologic AD dementia or controls, assess core neuropathologic features of AD (neuritic plaques, NPs; neurofibrillary tangles, NFTs, and evaluate commonly co-morbid neuropathologic changes: cerebral amyloid angiopathy (CAA, Lewy body disease (LBD, hippocampal sclerosis of the elderly (HS, and vascular brain injury (VBI. Genome-wide significance was observed for clinico-pathologic AD dementia, NPs, NFTs, CAA, and LBD with a number of variants in and around the apolipoprotein E gene (APOE. GalNAc transferase 7 (GALNT7, ATP-Binding Cassette, Sub-Family G (WHITE, Member 1 (ABCG1, and an intergenic region on chromosome 9 were associated with NP score; and Potassium Large Conductance Calcium-Activated Channel, Subfamily M, Beta Member 2 (KCNMB2 was strongly associated with HS. Twelve of the 21 non-APOE genetic risk loci for clinically-defined AD dementia were confirmed in our clinico-pathologic sample: CR1, BIN1, CLU, MS4A6A, PICALM, ABCA7, CD33, PTK2B, SORL1, MEF2C, ZCWPW1, and CASS4 with 9 of these 12 loci showing larger odds ratio in the clinico-pathologic sample. Correlation of effect sizes for risk of AD dementia with effect size for NFTs or NPs showed positive correlation, while those for risk of VBI showed a moderate negative correlation. The other co-morbid neuropathologic features showed only nominal association with the known AD loci. Our results discovered new genetic associations with specific neuropathologic features and aligned known genetic risk for AD dementia with specific neuropathologic changes in the largest brain autopsy study of AD and related

Full Text Available Background: A review of both Western and Indian literature shows that there are few comprehensive studies on pancytopenia. In India, the causes of pancytopenia are not well defined. This data, if available, would help in planning the diagnostic and therapeutic approach in patients with pancytopenia. Aim: To evaluate the cases of pancytopenia by peripheral smear and/or bone marrow aspiration and/or bone marrow biopsy to find out the etiology, clinical, hematological, and histomorphologic features of pancytopenia. Materials and Methods: Detailed hematological investigations a complete hemogram, peripheral smear examination, bone marrow aspiration, and biopsy examination were done. Results: The most common cause of pancytopenia in our study was megaloblastic anemia (56%, followed by hypoplastic/aplastic anemia (14%, hypersplenism (8% and post viral illness (6%. Conclusion: Megaloblastic anemia due to vitamin B12/folate deficiency seems to reflect the higher prevalence of pancytopenia in Indian subjects, putting hypoplastic/aplastic anemia in the second position, which is the leading cause for pancytopenia in the Western countries.

Eduardo Chachamovich

2009-05-01

Full Text Available OBJETIVO: Suicídio é uma das maiores causas de mortalidade ao redor do mundo, especialmente entre indivíduos jovens. Suicídio é considerado o desfecho de um fenômeno complexo e multidimensional, e decorrente da interação de diversos fatores. A associação entre psicopatologia e suicídio tem sido largamente estudada. Dentre os diagnósticos psiquiátricos associados a suicídio, depressão maior se destaca sobremaneira. Tais achados parecem ser confirmados em diferentes desenhos metodológicos e em distintas populações. Este artigo visa a revisar sucintamente as contribuições recentes acerca das características clínicas da depressão que se encontram vinculadas a casos de suicídio. Destacam-se também os esforços de prevenção, no sentido de, ao se detectar e tratar casos de depressão em serviços gerais de saúde, diminuir o risco de suicídio. REVISÃO: Referências recentes foram identificadas e agrupadas com o intuito de ilustrar as principais contribuições acerca da interface entre depressão e suicídio. Brevemente, a revisão de literatura aberta aponta para a grande prevalência do diagnóstico de depressão maior entre os casos de comportamento suicida. Traços psicopatológicos de agressão e impulsividade parecem exercer um papel relevante no desencadeamento de atos suicidas. Estratégias de prevenção foram também revisadas nos contextos internacional e brasileiro. De modo geral, a detecção e tratamento de depressão são capazes de reduzir as taxas de suicídio. CONCLUSÃO: No campo da pesquisa sobre comportamento suicida, os estudos têm tido caráter pragmático e produziram um panorama de fatores claramente associados ao suicídio, sem, no entanto, oferecer uma amarração teórica consistente para os achados. A crescente adoção de modernas técnicas traz uma ampliação das possibilidades de investigação. Para serem clinicamente úteis, os novos conhecimentos devem possibilitar um olhar mais profundo

On the basis of a clinico-pharmacological study using a new diuretic combination it is shown that not only the RIA determination, but also the measurement of the total amount of potassium in the body with the aid of the 40 K potassium-nuclide confirmed therapeutic efficacy. Furosemide (30 mg) and the combination furosemide-retard (30 mg) and triamterene (50 mg) influence the plasmarenin-aldosterone system (PRA-system) differently. After both furosemide alone and the combination, the plasma-renin activity increased significantly (p 40 /K potassium nuclide - decreased after 8 days of treatment with the combination of furosemide-retard and triamterene. Both methods have proved of value in the clinico-pharmacological examination of diuretics. They are of great importance, easy to apply, involve no exposure to radiation, and are inexpensive. (orig.)

Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi. We prospectively studied the clinico-laboratory profile and outcome of 358 children aged 1 day to 18 years diagnosed with scrub typhus from Chennai, South India. All children (100%) had fever. Eschar was seen in 67%. All children were treated with oral doxycycline and those with complications were treated with intravenous chloramphenicol/azithromycin. Rapid defervescence (within 48 h) after initiation of doxycline was seen in 306 (85%) and 52 (14.5%) developed complications. Multivariate logistic regression analysis revealed that children who had an elevated aspartate amino transferase (> 120 IU/L) and the presence of thrombocytopenia (platelet count less than 1 lac cells/mm 3 ) at admission had high risk of developing complications. The overall mortality rate in this series was 0.8%. Our 4-year study highlights the clinico-laboratory profile of Scrub typhus in children from Chennai, South India. Early recognition and prompt treatment reduces the complication and mortality. What is Known: • Scrub typhus is endemic to tsutsugamushi triangle, a geographical triangle extending from northern Japan in the east to Pakistan and Afghanistan in the west and northern Australia in the south. • There is paucity of data regarding its clinico-laboratory profile in neonates as well as its predictors of outcome. What is New: • Children who had an elevated AST and the presence of thrombocytopenia at admission had high risk of developing complications.

Background and purpose: This study seeks to: (a) quantify radiologic-pathologic discrepancy for pancreatic adenocarcinoma by comparing tumor size on conventional computed tomography (C-CT) and 3-dimensional CT (3D-CT) to corresponding pathologic specimens; and (b) to identify clinico-pathologic characteristics predictive of radiologic-pathologic discrepancy to assist radiotherapy planning. Materials and methods: Sixty-three patients with pancreatic adenocarcinoma and preoperative C-CT and volume-rendered 3D-CT imaging within 6 weeks of resection were identified. Maximum tumor diameter (MTD) was measured on pathology, C-CT, and 3D-CT and compared for each patient as well as among different clinico-pathologic subgroups. Results: There was a trend toward C-CT underestimation of MTD compared to final pathology (p = 0.08), but no significant difference between 3D-CT MTD and pathology (p = 0.54). Pathologic tumor size was significantly underestimated by C-CT in patients with larger pathologic tumor size (>3.0 cm, p = 0.0001), smaller tumor size on C-CT ( 90 U/mL, p = 0.008), and location in the pancreatic head (p = 0.015). A model for predicting pathologic MTD using C-CT MTD and CA19-9 level was generated. Conclusions: 3D-CT may allow for more accurate contouring of pancreatic tumors than C-CT. Patients with the above clinico-pathologic characteristics may require expanded margins relative to tumor size estimates on C-CT during radiotherapy planning.

Purpose: To report the results of a three-year observational pilot study of lung cancer screening with low dose computed tomography (CT) and to present the study design of a randomised clinical trial named as Italung CT. Materials and methods: Sixty (47 males and 13 females, mean age 64{+-}4.5 years) heavy smokers (at least 20 packs-year) underwent three low-dose spiral CT screening tests one year apart on a single slice or multislice CT scanner. Indeterminate nodules were managed according to the recommendations of the Early Lung Cancer Action Project. Results: Indeterminate nodules were observed in 33 (55%) of the subjects (60% at the baseline screening test, 24% at the first annual test and 16% at the second annual test). The size of the largest indeterminate nodule was <5mm in diameter in 20 subjects. 10 of whom showed the nodule at the baseline test. Forty-five subjects (75%) completed the first annual test and 42 (70%) the second annual test. One (1.6%) prevalent lung cancer (adenosquamous carcinoma) and one (2.2%) incident lung cancer (small cell cancer at the first annual examination) were observed, as well as pulmonary localisation of Hodgkin's lymphoma (at the second annual test). In addition, one subject underwent lung surgery for a chondromatous hamartoma. Conclusions: The results of the pilot study are substantially in line with those of other observational studies of greater sample size. This justifies optimism about the reliability of the results in the screened arm of the Italung Ct trial which hast just began.

Full Text Available A persistência da veia cava superior esquerda com ausência da veia cava superior direita é uma anomalia rara, com menos de 150 casos descritos na literatura. A não-obliteração e regressão da veia cardinal anterior esquerda durante o desenvolvimento embriológico promove uma variação sistêmica de retorno venoso ao coração, com persistência da veia cava superior esquerda. Sua incidência varia de 0,3% em pacientes sem alterações cardíacas congênitas concomitantes a 4,3% naqueles com cardiopatias. Na maioria das vezes coexiste a veia cava superior direita, porém se houver regressão e degeneração da veia cardinal anterior direita, implicará a sua ausência e a drenagem venosa para o coração será feita pela veia cava superior esquerda ao átrio direito, através do seio coronariano. Mostramos um caso de um paciente submetido a radiografia de tórax e tomografia computadorizada para avaliação de doença pulmonar obstrutiva crônica, tendo como achado a persistência da veia cava superior esquerda com ausência da direita, sem qualquer cardiopatia associada e com a drenagem cardíaca sendo feita, através do seio coronariano, para o átrio direito.Persistent left superior vena cava with absent right superior vena cava is a rare anomaly, with less than 150 cases reported in the literature. Congenitally persistent left superior vena cava is the most common variant of systemic venous return to the heart, resulting embryologically from failure of the left anterior cardinal vein to become obliterated. Its incidence varies from 0.3% in patients with otherwise normal heart to 4.3% in patients with congenital heart disease. In the majority of the patients, a right superior vena cava is present as well, but rarely the right anterior cardinal vein degenerates resulting in the absence of the normal right superior vena cava. The blood from the right side is carried by the persistent left superior vena cava to the right atrium through the

Inherited ABO blood groups have been shown to play possible contributions in the pathogenesis of various gynecologic and non-gynecologic carcinomas. With regard to gynecologic carcinomas, there is a confined number of studies that explored the relationship between ABO blood group and endometrial carcinoma (EC) in the PubMed-indexed literature. To the best of our knowledge, no such study has ever been conducted in Saudi Arabia. Our study has two objectives: (I) to determine the prevalence of ABO blood groups among Saudi patients with EC, and (II) to explore the relationship between ABO blood group and several clinico-pathological prognostic parameters (namely: menopausal status [age], body mass index [BMI], tumor grade, FIGO [Fédération Internationale de Gynécologie et d'Obstétrique] stage and recurrence) in Saudi patients with EC. A retrospective cross-sectional study from 01-January-2010 to 31-July-2014 was conducted at King Faisal Specialist Hospital & Research Centre, Riyadh, Saudi Arabia - a referral tertiary healthcare institute. One-hundred and fourteen patients (n=114) were included in the study. Clinico-pathological data were extrapolated from medical records, and their association with ABO blood groups were evaluated. Categorical data were presented as number of cases (n) and percentages (%). Two-tailed Chi-square test was used for univariate analysis. For all purposes, p values 28 kg/m 2 (84.2%), diagnosed with early FIGO stage I-II (76.3%) and developed no recurrence (86.8%). The frequencies of ABO blood group types A, B, AB, and O were 28.1%, 12.3%, 3.5% and 56.1%, respectively. When ABO blood groups were analyzed as four different types (A, B, AB and O), O-type was the most common ABO blood group in pre- and post-menopausal EC patients (43.8% and 58.2%, respectively; p=0.14). There were no statistically significant correlations between ABO blood groups and all the examined clinico-pathological factors. Moreover, when ABO blood groups were

2010-04-01

Full Text Available Objectives: To systematize the clinico-radiological symptoms and course of bisphosphonate-related osteonecrosis of jaw bone and to evaluate the diagnostic potential of various radiological techniques to detect mild osteonecrosis in each stage of the disease.Material and Methods: The sample consisted of 22 patients previously diagnosed with extraoral malignant disease. Diagnosis was based on a clinical examination in conjunction to digital panoramic radiography and cone beam computed tomography (CBCT. Two dentomaxillofacial radiologists reviewed all images.Results: Twenty patients showed mandibular involvement clinically, while two others had a maxillary involvement. Four stages of the disease were proposed based on the clinico-radiological findings. Subclinical cortical and lamina dura thickening was detected with only three-dimensional CBCT and periapical images, while ulceration and cortical bone thickening was detected only by three-dimensional CBCT. Mixed sclerotic, lytic bone destruction involving alveolar and basal bone with or without encroachment on the mandibular canal, pathological mandibular fractures were detected by two-dimensional panoramic and three-dimensional CBCT images. Other findings are non healing extraction sockets, periapical radiolucencies, osteolysis, sequestra, oroantral fistula, and periosteal new bone formation.Conclusions: The present study showed that bisphosphonate-related osteonecrosis of jaw bone occurs in four distinct clinico-radiological stages. For mild cases, panoramic image diagnosis was much less obvious, whereas cone beam computed tomography was able to fully characterise the bony lesions and describe their extent and involvement of neighbouring structures in all cases. Thus cone beam computed tomography might better contribute to the prevention of bisphosphonate-related osteonecrosis of jaw bone as well to the disease management.

Full Text Available As micoses do sistema nervoso central não têm merecido atenção cuidadosa dos neurologistas. Elas afetam o neuraxe em diferente percentagem: a granulomatose criptocóccica (torulose é a mais freqüente, seguindo-se a actinomicose; a granulomatose paracoccidióidica só excepcionalmente determina lesões meningoencefálicas. Do ponto de vista clínico, as neuromicoses podem ser divididas em duas formas: tumorais encefalomedulares e meningíticas. Estas predominam sobre as tumorais, das quais são mais freqüentes as de localização encefálica. Não são raros os quadros mistos, meningoencetálicos. As formas tumorals encefálicas abrangem vários tipos anátomo-patológicos - abscesso, granuloma, nódulos e cistos - sendo mais comuns os dois primeiros, todos êles produzindo o quadro clinico da síndrome hipertensiva intracraniana. As formas meningomedulares, em geral, são secundárias às lesões ósseas vertebrais, sendo a actinomicose, por ser a mais osteófila, a micose que mais freqüentemente atinge a medula. Nestes casos, o quadro clínico da síndrome compressiva é o mais comum. As meninges participam do processo fúngico, na maior parte dos casos; as manifestações clínicas variam desde o simples meningismo, até as meningites purulentas e meningoencefalites graves, havendo a possibilidade de se formarem aracnoidites císticas, ependimites e bloqueios ventriculares, do aqueduto ou mesmo do canal raquidiano. O diagnóstico das micoses do sistema nervoso central é comumente um "achado de autópsia". Somente a verificação do cogumelo no líquor e o seu isolamento permitem um diagnóstico seguro. Outros dados liquóricos, quando bem interpretados com os achados clínicos e neurológicos, orientam o analista na pesquisa do agente fúngico. O quadro anátomo-patológico nada tem de caraterístico, a não ser a presença do agente parasitário e só o seu encontro firma o diagnóstico. Examinamos 25 casos de granulomatose

Basaloid Squamous Cell Carcinoma of the Head and Neck: Subclassification into Basal, Ductal, and Mixed Subtypes Based on Comparison of Clinico-pathologic Features and Expression of p53, Cyclin D1, Epidermal Growth Factor Receptor, p16, and Human Papillomavirus

2017-07-01

Full Text Available Background Basaloid squamous cell carcinoma (BSCC is a rare variant of squamous cell carcinoma with distinct pathologic characteristics. The histogenesis of BSCC is not fully understood, and the cancer has been suggested to originate from a totipotent primitive cell in the basal cell layer of the surface epithelium or in the proximal duct of secretory glands. Methods Twenty-six cases of head and neck BSCC from Asan Medical Center, Seoul, Korea, reported during a 14-year-period were subclassified into basal, ductal, and mixed subtypes according to the expression of basal (cytokeratin [CK] 5/6, p63 or ductal markers (CK7, CK8/18. The cases were also subject to immunohistochemical study for CK19, p53, cyclin D1, epidermal growth factor receptor (EGFR, and p16 and to in situ hybridization for human papillomavirus (HPV, and the results were clinico-pathologically compared. Results Mixed subtype (12 cases was the most common, and these cases showed hypopharyngeal predilection, older age, and higher expression of CK19, p53, and EGFR than other subtypes. The basal subtype (nine cases showed frequent comedo-necrosis and high expression of cyclin D1. The ductal subtype (five cases showed the lowest expression of p53, cyclin D1, and EGFR. A small number of p16- and/or HPV-positive cases were not restricted to one subtype. BSCC was the cause of death in 19 patients, and the average follow-up period for all patients was 79.5 months. Overall survival among the three subtypes was not significantly different. Conclusions The results of this study suggest a heterogeneous pathogenesis of head and neck BSCC. Each subtype showed variable histology and immunoprofiles, although the clinical implication of heterogeneity was not determined in this study.

Naik Chandra

2007-01-01

Full Text Available Background: Pitted keratolysis is a common dermatological condition. However, very few studies are available on the clinical characteristics and epidemiological features of this disorder from India and abroad. Materials and Methods: Fifty patients from rural area of Kolar at Sri R.L.J.H. and S.N.R. Hospital, presenting with clinically distinctive lesions of pitted keratolysis were included in the study. Cases were interviewed with particular emphasis on triggering factors and findings were recorded. Investigations like Gram′s stain, culture studies, Wood′s ultraviolet light examination, histopathology etc, was done in selected cases to ascertain the clinical diagnosis. Results: Age of the patients varied from 20 to 40 years in 52% with male preponderance in 82% of cases. Duration of the disease varied from 15 days to five years, most of the patients were bare-footed farmers (62% of cases. Hyperhidrosis and pruritus were most frequently observed symptoms in 70% and 60% of patients. Most of the patients presented with the characteristic pits which varied from 1 to 50 in number in 56 % of cases, located predominantly on the pressure bearing areas in 92% of cases and depth of the pits varied from 1 to 2 mm in 60% of cases. Associated skin conditions recorded in present study were fissuring of soles in 38%, psoriasis 10%, dermatophyte infections in 6%, planter warts 6% and Corynebacterial triad and corn in 2% of patients each. Discussion: Affection of bare-footed individuals, male preponderance, presence of hyperhidrosis and occurrence of lesions over pressure bearing areas of soles, observed in the present study were consistent with earlier studies on the subject. However, pruritus as commonest presenting symptom reported by 60% patients in the present study, has not been documented in the previous studies. Conclusion: Pitted keratolysis is fairly common in bare footed male farmers of rural India. The condition is predominantly seen over the pressure bearing areas of sole and hyperhidrosis is common precipitating factor. Pruritus, a common presenting symptom observed in this study has not been reported earlier.

Full Text Available Although clinical criteria, laboratory diagnosis and treatment are well established, scanty attention has been paid to prevalence and pattern of viral warts in India. HIV is widely prevalent and its influence on the number and morphology of viral warts has not yet been studied in our setup. Hence, this study was undertaken. One hindered and forty four cases of viral warts were studied between September 2000 and June 2002 at the department of Dermatology and STD, JIPMER, Pondicherry. These included 81childeren and 63 adults. In Children, viral warts were most commonly seen in the age group of 10to14 years (41.9%, whereas in adults, the most commonly seen in the age 14to20 years (46.03%. The average age at presentation was 11.5 years. The male to female ratio was 2.2 to 1 in children and 1.8 to 1 in adults. Family history of warts was observed in 27.7% of the cases. In children, multiple site involvement (62.9% was more common than single site involvement. The most commonly involved site was hand in children as also in adults. In adults, single site involvement (66.6%was more common than multiple site involvement. The most common type of wart seen in both children and adults was the common wart.

Neonatal breast hypertrophy is a common phenomenon in term infants, superadded infection can lead to mastitis and that can progress to breast abscess with short and long term detrimental effects. Our effort is to study the prevalence, risk factors, the current microbial profile and sensitivity pattern in these infections in order to suggest an optimal treatment plan for these patients. Case series. Hospital based study conducted in Kashmir on the native population. 2011 to 2013. 32 neonates with features of mastitis or abscess were included in the study. Demographic and clinical data, laboratory work-up were recorded for all these patients in a patient form. Gram stain of the purulent nipple discharge or pus obtained on drainage was done and the specimens were culture plated. Antibiotic sensitivity was determined by disk diffusion and categorized by current Clinical and Laboratory Standards Institute (CLSI) guidelines. Most babies were full term, the age range was 6-48 days. Peak incidence for mastitis was in the 2nd week and for abscess in the 4th week. The ratio of male: female was 1:2 in the entire group, there was greater preponderance of female involvement with increasing age. Massage for expression of secretions a common practice in the study population had been done in 15 patients, especially in male babies. The babies were generally well and associated skin pustulosis was common. Laboratory workup showed polymorphonuclear leucocytosis and CRP positivity. Gram staining showed gram positive cocci in 13 patients and gram negative rods in 1 patient. Culture revealed Staphylococcus aureus in 18, E.col in 2, klebsiella in 1 patient and was sterile in 2 patients. Most strains of Staphylococcus aureus were resistant to macrolides and penicillins. Fifteen were methicillin sensitive and 3 were resistant but were sensitive to amikacin, ofloxacin and vancomycin. Gram negative rods were sensitive to, aminoglycosides, chloramphenicol, quinolones, piperacillin-tazobactum and cefoperazone-sulbactum, but were resistant to cephalosporins including third generation cephalosporins. Treatment with oral antibiotic was not successful. Patients responded well to open drainage via a stab incision away from the breast mound; 4 patients were managed by repeated needle aspirations. IV antibiotics were prescribed in all patients for 2-5 days, followed by oral continuation therapy of 7-14 days. From our study, we can conclude that parental counseling to avoid massage, and early treatment for pustulosis is important to prevent mastitis. Intravenous antibiotics should be used for this condition guided by gram stain or culture sensitivity once available. Empirically a drug with good anti-staph cover may be instituted till appropriate reports are available. Incision drainage gives uniformly good results, though; multiple sittings of needle drainage may obviate the need for incision drainage. Therapy can be shifted to oral drugs once clinical improvement is seen.

Full Text Available Background: Generally it is well established fact that geographical distribution of the fungi may change from time to time; hence this study was planned. Aim and Objectives: To analyze the prevalence of superficial mycoses, its clinical presentation and species identification of the fungal isolates responsible for the disease. Material and Methods: A total 125 clinically diagnosed cases of superficial mycoses visiting Dermatology and Venereology outpatient department of Bharati Hospital, Sangli, for a period of one year were included in the study. Specimens like skin scrapping, nail clipping, hair were collected and subjected to KOH mount and culture. Identification of species was done by macroscopic examination of culture, tease mount and other physiological tests including Urease test, Hair perforation tests and Germ tube test. Results: Superficial mycosis was more common in the age group of 21-30 years (28% and in males (60.8%. The infection was more common in students (29.6%. Tinea corporis (42.4% was the commonest clinical type followed by tinea cruris (22.4%. 61.6% cases were positive by direct microscopy and 60.8% cases showed culture positive. Out of 125 samples, dermatophytes were grown in 63 cases (82.89% followed by non dermatophytic moulds in 10 cases (13.16% and Candida albicans in 3 cases (3.95%. The most common isolate among dermtophytosis was T. rubrum (46.05% followed by T. mentagrophyte (25%. Conclusion: It was concluded that along with dermatophytes, non dermatophytic moulds are also important to cause of superficial mycoses

To evaluate specific features of the course of chronic gastritis (CG), morphofunctional condition of gastric mucosa, vegetative regulation, adrenergic and cholinergic shifts, histamine metabolism and effects of exogenic and endogenic risk factors in CG patients; to study clinicopathogenetic variants of CG. A total of 311 CG patients aged from 16 to 72 years were studied. They were divided into three groups by their gastric mucosa condition. The control group consisted of 30 healthy donors. The following parameters were studied: visual and histological condition of gastric mucosa, total acidity, the levels of free hydrochloric acid, pepsin, bioelectric gastric activity, general autonomic tonicity, cholinesterase activity. Three clinicopathogenetic variants of the disease have been identified. Variant 1 was characterized by a recurrent course, subjective manifestation of the disease only in exacerbation, surface (primarily antral) mucosal affection, normal or enhanced secretory and motor functions of the stomach, adequate reaction of acid production to caffeine and histamine stimulation, parasympathicotonia, absolute hyperhistaminemia, relative hypoacetylcholinemia, subnormal urinary excretion of adrenalin. Variant 2 manifested with rare recurrences, longer and more severe exacerbations, frequent spontaneous and provoked aggravations, moderate focal atrophy of the mucosa, secretory insufficiency with adequate reaction to histamine and minor to caffeine stimuli, hypomotor gastric dyskinesia, vegetative eutonia, normohistaminemia, absolute hypoacetylcholinemia, subnormal urinary excretion of noradrenaline. Variant 3 runs without definite remissions and exacerbations, with continuous abdominal pain and dyspepsia, frequent spontaneous aggravations, marked extended mucosal atrophy with secretory insufficiency up to achlorhydria, no stimulation of acid production in response to caffeine and histamine, gastric hypomotility, sympathicotonia, absolute hypohistaminemia, hypoacetylcholinemia, normal urinary excretion of catecholamines. The findings expand our knowledge about clinicopathogenetic variants of CG and necessitate new approaches to development of effective methods of CG prevention and treatment.

Full Text Available Nieves Gonzalo, Carlos MacayaInterventional Cardiology, Cardiovascular Institute. Hospital Clinico San Carlos, Instituto de Investigación Sanitaria del Hospital Clinico San Carlos, Madrid, SpainAbstract: Coronary stents have improved very significantly the immediate and long-term results of percutaneous coronary interventions. However, once the vessel has healed, the scaffolding function of the stent is no longer needed, and the presence of a permanent metallic prosthesis poses important disadvantages. This has led to the idea of creating new devices that are able to provide mechanical support for a determined period and then disappear from the vessel, allowing its natural healing and avoiding the risks associated with having a permanent metallic cage, such as stent thrombosis. Absorbable stents currently appear as one of the most promising fields in interventional cardiology. The present article will review the available clinical evidence regarding these devices at present and their future perspectives.Keywords: absorbable stent, bioresorbable stent, absorb, percutaneous coronary intervention

Eun-Joo Jung

2011-01-01

Full Text Available Background: The over expression of fascin, extracellular matrix metalloproteinase inducer (EMMPRIN, and ezrin proteins has been associated with poor prognosis in various carcinomas and sarcomas. However, very few studies have reported the relationship between the expression of fascin, EMMPRIN, and ezrin proteins and the clinico-pathologic parameters of colorectal carcinomas. Aims: The aim was to investigate the relationship between fascin, EMMPRIN, and ezrin proteins in colorectal adenocarcinomas and their correlation with clinico-pathologic parameters. Settings and Design: The expression of fascin, EMMPRIN, and ezrin proteins was studied in 210 colorectal adenocarcinoma patients through immunohistochemical staining. Materials and Methods: Immunohistochemical staining by the avidin-biotin peroxidase method was done. The scoring of each protein expression was done and divided into three groups (negative, low-, and high-expression groups. Statistical Analysis: A chi-square test, and Kendall′s tau-b correlation test were used for comparing. Survival analysis was performed using the Kaplan-Meier method with log-rank tests and the Cox proportional hazard model. Results: The percentages of the high-expression group of fascin, EMMPRIN, and ezrin proteins in colorectal adenocarcinomas were 24%, 73%, and 62%, respectively. Weak positive correlations were observed among these protein expressions. An increased expression of the fascin protein was significantly associated with advanced tumor depth and shorter survival times, and a high expression of fascin protein was an independent prognostic factor in univariate and multivariate survival analyses. EMMPRIN and ezrin protein expressions were not associated with the clinico-pathologic parameters. Conclusions: The high expression of fascin protein may be an unfavorable prognostic marker for individual colorectal cancer patients.

Mild encephalitis/encephalopathy with reversible splenial lesion (MERS) is a rare clinico-radiological entity characterized by the magnetic resonance imaging (MRI) finding of a reversible lesion in the corpus callosum, sometimes involved the symmetrical white matters. Many cases of child-onset MERS with various causes have been reported. However, adult-onset MERS is relatively rare. The clinical characteristics and pathophysiologiccal mechanisms of adult-onset MERS are not well understood. We reviewed the literature on adult-onset MERS in order to describe the characteristics of MERS in adults and to provide experiences for clinician. We reported a case of adult-onset MERS with acute urinary retension and performed literature search from PubMed and web of science databases to identify other adult-onset MERS reports from Januarary 2004 to March 2016. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed on selection process. And then we summarized the clinico-radiological features of adult-onset MERS. Twenty-nine adult-onset MERS cases were reviewed from available literature including the case we have. 86.2% of the cases (25/29) were reported in Asia, especially in Japan. Ages varied between 18 and 59 years old with a 12:17 female-to-male ratio. The major cause was infection by virus or bacteria. Fever and headache were the most common clinical manifestation, and acute urinary retention was observed in 6 patients. All patients recovered completely within a month. Adult-onset MERS is an entity with a broad clinico-radiological spectrum because of the various diseases and conditions. There are similar characteristics between MERS in adults and children, also some differences.

Full Text Available RESUMO O objetivo deste trabalho foi descrever os achados eletrocardiográficos de 11 onças- pardas (Puma concolor. Os animais foram sedados com 0,15mg/kg de detomidina associado a 5mg/kg de cetamina e mantidos anestesiados com sevoflurano (GSEVO, n=6 ou isoflurano (GISO, n=5. A frequência cardíaca foi de 95 ± 13bpm. As alterações observadas nos animais no GSEVO foram: atrial standtill com condução ventricular, episódios isolados de contração ventricular prematura, bloqueio atrioventricular de primeiro grau, diminuição da amplitude do complexo QRS, onda S profunda e aumento da amplitude da onda T. No grupo GISO, observou-se bloqueio de ramo direito do feixe de His, bloqueio atrioventricular de primeiro grau e aumento da amplitude da onda T. Arritmias não puderam ser associadas ao uso dos anestésicos inalatórios devido à não sensibilização do miocárdio às catecolaminas. Achados como o BAV de primeiro grau pode ter ocorrido devido ao uso de agonistas α-2 adrenérgicos. Este estudo aumentou o conhecimento sobre as alterações eletrocardiográficas em onças-pardas anestesiadas, entretanto mais estudos são necessários para correlacionar estes achados ao uso de agentes anestésicos.

Full Text Available Abstract Background Fascin is a globular actin cross-linking protein, which plays a major role in forming parallel actin bundles in cell protrusions and is found to be associated with tumor cell invasion and metastasis in various type of cancers including oral squamous cell carcinoma (OSCC. Previously, we have demonstrated that fascin regulates actin polymerization and thereby promotes cell motility in K8-depleted OSCC cells. In the present study we have investigated the role of fascin in tumor progression of OSCC. Methods To understand the role of fascin in OSCC development and/or progression, fascin was overexpressed along with vector control in OSCC derived cells AW13516. The phenotype was studied using wound healing, Boyden chamber, cell adhesion, Hanging drop, soft agar and tumorigenicity assays. Further, fascin expression was examined in human OSCC samples (N = 131 using immunohistochemistry and level of its expression was correlated with clinico-pathological parameters of the patients. Results Fascin overexpression in OSCC derived cells led to significant increase in cell migration, cell invasion and MMP-2 activity. In addition these cells demonstrated increased levels of phosphorylated AKT, ERK1/2 and JNK1/2. Our in vitro results were consistent with correlative studies of fascin expression with the clinico-pathological parameters of the OSCC patients. Fascin expression in OSCC showed statistically significant correlation with increased tumor stage (P = 0.041, increased lymph node metastasis (P = 0.001, less differentiation (P = 0.005, increased recurrence (P = 0.038 and shorter survival (P = 0.004 of the patients. Conclusion In conclusion, our results indicate that fascin promotes tumor progression and activates AKT and MAPK pathways in OSCC-derived cells. Further, our correlative studies of fascin expression in OSCC with clinico-pathological parameters of the patients indicate that fascin may prove to be useful in prognostication and

Increasing human epidermal growth factor receptor 2 (HER2) immunohistochemistry (IHC)/fluorescence in situ hybridisation (FISH) dual-equivocal breast tumours are reported after the 2013 American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP) guideline update. The aim of this study is to investigate the clinico-pathologic characteristics, treatment patterns and disease outcome of these patients with HER2 dual-equivocal tumours. Patients with HER2 IHC 2+ and available FISH results were retrospectively analysed from the Comprehensive Breast Health Center, Shanghai Ruijin Hospital. The 2013 ASCO/CAP guideline was applied to define HER2-positive, dual-equivocal and -negative groups. Patient characteristics, systemic treatment patterns and survival were compared among these groups. Reverse transcriptase-polymerase chain reaction-based assays were applied to test HER2 mRNA expression level. Among 691 patients included, 133 (19.25%) were HER2 positive, 25 (3.62%) were HER2 dual-equivocal and 533 (77.13%) were HER2 negative. Univariate and multivariate analyses stated that HER2 dual-equivocal tumours shared more similarity with HER2-negative tumours, whereas HER2-positive tumours had rather different clinico-pathologic features. HER2 dual-equivocal tumours had similar HER2 mRNA levels compared with HER2-negative tumours (P = 0.26), which were much less compared with HER2-positive breast cancer. Besides, adjuvant systemic treatment patterns were comparable between HER2-negative and dual-equivocal tumours, and none of HER2 dual-equivocal patients received anti-HER2 treatment. There was no survival difference among these three groups (P = 0.43). HER2 dual-equivocal tumours share more similarity with HER2-negative disease in terms of clinico-pathologic features, HER2 mRNA levels, adjuvant systemic treatment patterns and disease outcome, which deserves further clinical evaluation.

Full Text Available There were investigated 50 cytological preparations after fibro-optic bronchoscopy of 10 patients with cervical spinal cord injuries. The dynamics of broncho-pulmonary complications of spinal cord injuries was estimated on the basis of cytological broncho-alveolar lavage fluid investigations. In the work there were used clinico-neurologic methods, radiological (computer tomography and magnetic resonance imaging, endoscopic (fibro-optic bronchoscopy and cytomorphological investigations. Cytomorphological investigations of broncho-alveolar lavage fluid were carried out on the 3-4, 7, 14, 30th days. Cellular composition of the broncho-alveolar wash-out (endopulmonary cytogramme was estimated by calculation of more than 100 cells in 3 fields of the immersion microscope coverage. Quantitative changes of cellular elements were taken into account with respect to normal cell amount. The results were analyzed according to the average out method. Quantitative changes of inflammatory elements in endopulmonary cytogramme were determined by the degree of endobronchitic manifestations and were corresponding to clinico-radiological picture of development of broncho-pulmonary complications in different periods of spinal cord injury

Full Text Available A hemiatrofia facial progressiva (HFP é doença esporádica de etiologia não esclarecida, caracterizada por progressiva atrofia e deformação de um dos lados da face. Os relatos e interpretações de comprometimento do sistema nervoso central na HFP, conforme deduzido pela ocorrência de crises epilépticas em alguns pacientes e pela documentação por pneumencefalografia e CT em pequenas séries de pacientes, são contraditórios. Examinamos três pacientes do sexo feminino com HFP, uma com epilepsia, com o objetivo de obter mais informações sobre a patogênese da doença. MÉTODOS: Realizamos exames de ressonância magnética nuclear (RMN de rotina da cabeça e face. RESULTADOS:Apenas a paciente com epilepsia apresentou achados patológicos no cérebro. Estes eram confinados ao hemisfério homolateral à hemiatrofia facial: dilatação monoventricular, dismorfismo meningo-cortical e alterações na substância branca. CONCLUSÕES: As alterações morfológicas verificadas à RMN assim como os achados neurorradiológicos e histopatológicos mostrados em revisão da literatura indicaram que a hemiatrofia homolateral é achado típico para um subgrupo de pacientes com HFP, mas não indica um modelo de simples processo atrófico. Reconsideramos a possibilidade de uma meningoencefalite crônica com acometimento vascular como possível causa do ocasional envolvimento cerebral na HFP.

Intestinal tuberculosis is still common in developing countries. In 186 patients with intestinal tuberculosis, clinical features, radiological findings and complications were carefully recorded and compared with those from earlier studies with a view to study any possible changes after the liberal use of antitubercular drugs. Sixty two percent of the patients in the present series had had prior exposure to antitubercular drugs. The incidence of systemic symptoms like fever and anorexia, alternating diarrhoea and constipation, peritoneal and lymph node involvements and associated pulmonary lesions were less frequently observed. On the other hand, an indolent and complicated course with intestinal obstruction (47 %) and lower gastrointestinal bleeding (5.5 %) and frequent colonic involvement (19 %) often necessitating surgical intervention appeared to have become more frequent than reported in earlier series. Awareness of these changes in the clinical profile of intestinal tuberculosis should be helpful in the diagnosis and management of the condition. (author)

Full Text Available BACKGROUND Cervical lymphadenopathy is a common finding in day today surgical practice which poses a challenge to the clinician because clinical findings may not always help in arriving at a possible cause. Meticulous history taking and thorough clinical examination most of the times helps the clinician in diagnosis but for confirmation and planning management histological examination always helps. Fine Needle Aspiration Cytology is emerging as a first line diagnostic tool in evaluating lymphadenopathy. The aim of this study was to identify various causes of cervical lymphadenopathy and to identify the distribution in various age groups and to compare clinical findings with pathological findings. This is a prospective study on Cervical Lymphadenopathy conducted on 130 patients in Department of General Surgery at Sri Venkateswara Ramnarain Ruia Government General Hospital, Tirupati from September 2015 to October 2016. MATERIALS AND METHODS This was a prospective study conducted in department of general surgery in Sri Venkateswara Ramnarain Ruia Government General Hospital, Tirupati from September 2015 to October 2016. A total of 130 patients were included in the study. Detailed history was taken and clinical examination was done, required investigations were done, Fine Needle Aspiration Cytology was done in all the cases. Results were analysed. RESULTS Tuberculosis was the most common cause (42% followed by non-specific lymphadenitis (25%. Women were more affected than men. Young adults in 18-30 years age group were more affected by TB whereas patients in age group 51-60 were affected with malignancy. Fine Needle Aspiration Cytology was conclusive in 125 cases. CONCLUSION Tuberculosis is the most common cause followed by non-specific lymphadenitis, metastatic lymph nodes. Fine Needle Aspiration Cytology is simple, quick and cheap investigative tool in cervical lymphadenitis evaluation.

To determine the different radiological findings in the lung of children presenting human ummunodeficiency virus (HIV) infection. We assess the different radiological patterns and their prevalence. The study deals with 58 children presenting HIV infection. All underwent plain chest radiography at some time during the course of their disease to determine the cause of different respiratory symptoms (dyspnea, fever, cough, etc.).Bronchial lavage was performed in all the children who required intubation due to severe respiratory distress. The results of chest X-ray were normal in 29 children despite the existence of pulmonary symptomatology. The other 29 patients presented pulmonary, including 21 cases of pneumonia (36,2%) in 16 patients, in seven of whom the pathogen was determined by blood culture. Four cases of Pneumocystis carinii (6.89%) were diagnosed by means of bronchial lavage. There were nine children with interstitial pneumonitis, five of the lym-phoid variant (8.62%) and four of unknown origin (6.89%). In contrast to the findings in adults, we have had no cases of pulmonary tuberculosis among our patients The rates of morbidity and mortality among HIV-infected children are associated with lung involvement. However, the prevalence has decreased progressively since the introduction of antiviral agents. Recurrent bacterial pneumonia and opportunistic Pneumocystis carinii infection are the most common types of acute pulmonary involvement. Interstitial pneumonitis usually develops a chronic course.

Genital warts is a disease of young adults and correlates with sexual maturity. The majority of patients were poor socio-economically, non-promiscuous and not addicted to alcohool. Most of the with the disease, were single and the women . married, reflecting the differing sources of acquisition of the disease. Homosexuality played a significant role in the acquisition of perianal warts in males. The mean incubation period. Warts were more numerous in women.. Long foreskins, by presenting a more moist environment probably preispose to the acquisition and propagation of warts. Personal hygiene soon after coitus did not seem significant, in the prevention of warts Cutaneous warts were associated in 8% of the cases. Concomitant sexually transmitted infections were present in 38.5% of the patients. Genital warts showed a preferential distribution at sites frequently subjected to the trauma of coitus.

Objective: To evaluate the risk factors involved, mode of presentation and the pattern of malignancies in hypopharynx. Design: It was a prospective study. Place and Duration of Study: The study was conducted at the Departments of Otolaryngology and pathology, Combined Military Hospital Kharian, over a period of two years (may 1998 to April 2000). Subject and Methods: Thirty patients with malignant tumors of the hypopharynx were studied. Evaluation was done by detailed history for presenting symptoms and possible risk factors, endoscopy and histological examination of the specimen. Results: out of 30 patients, 24 were males and 6 females with a male to female ratio of 4:1. A majority of them was in the 7th decade. History of tobacco intake in the form to smoking or chewing was present in 87%. Presenting symptoms were dysphagia, pain in the throat and neck mass. Most common site of origin was pyriform fossa (53%). All the malignant tumors were squamous cell carcinomas. Well-differentiated category was the most common (60%), followed by moderately-differentiated (26.5%) and poorly-differentiated (13.5%) varieties. Conclusion: Our findings are consistent with contemporary literature. There are close similarities with regard to sex tobacco use, presentation and type of malignancy. In our study, well-differentiated category was more common than the poorly differentiated one. (author)

Schistomiasis mansoni infection is a leading cause of severe morbidity in the Sudan. Most of the morbidity and mortality are due to the development of hepatic periportal fibrosis and consequent portal hypertension and bleeding varices. This is a hospital-based, retro-prospective study in the period from 1980-1995. Liver disease (i.e. periportal fibrosis) and its clinical presentation were studied in relation to the degree of fibrosis and other pathological, haematological, and biochemical parameters. The study identified the common hospital presenting symptoms, assessed factors that influence pathogenesis of periportal fibrosis and its severity, as well as, defined criteria which predict those patients who are at risk of bleeding. 898 patients were included. The common presenting symptoms were left hypochondrial pain, haematemesis and enlarged spleen (Towal). Males were found to have an increase prevalence of periportal fibrosis. Splenomegaly was found in almost all patients of the study of different age groups, but spleen size didn't show any significant difference between bleeders and non-bleeders (p=0.28). A sharp rise in the prevalence of bleeding was noted after the age of 16 years. Upper gastrointestinal bleeding was found to be more common

Since january 1970-december 1982, 58 patients underwent emergently appendectomy for acute appendicitis. 31 (53,4 percent) where males; the average age was 21 +/- 2,3 years (M +/- SEM). The duration of symptoms ranged from 1-6 hours (10,3 percent of cases) to over 48 hours, before the hospital admission (15,4 percent of cases). 27 patients (46,5 percent) had a clinical examination at home by a physician. 21 patients (36,4 percent) came to hospital emergency unit without previous physical examination; 10 (17,2 percent) were transferred from other departments. In 6,9 percent of cases was present a perforated appendicitis with peritonitis. During operation, in 50 percent of patients was performed a therapeutic peritoneal lavage. In 63,7 percent of cases multiple drains were placed in peritoneal cavity. In all patients was effected postoperative antibiotic profilaxis. The mortality rate was 3,4 percent. General complications were observed more in patients with perforated appendicitis. This review suggests the following remarcable data: morbidity of this disease is still high; the physical examination is more important than laboratory work (especially in the elderly patients, which are often immunodepressed and in children, with leucocitosis-lack at hospital admission); early surgery is the most important factor to the improvement of prognosis in these cases and the results of surgical treatment are improved by large vertical incisions, peritoneal lavage and application of multiple intracavitary drains.

Full Text Available Background: Human Immunodeficiency Virusinfected women account for almost half the number of cases of HIV worldwide. Despite reduction in HIV prevalence among the population, the percentage of Indian women contracting the disease seems to have increased. The social implications are also different in females. Materials and Methods: This prospective observational study was conducted from September 2009 to July 2011 at tertiary care hospitals attached to the Kasturba Medical College Mangalore, on a group of 200 HIV-positive patients. Patients above 18 years of age diagnosed with HIV as per National AIDS Control Organisation guidelines were included in the study. Clinical profile among women and men was compared with respect to clinical presentation, disease detection, CD4 count and response of family and society. Results: Clinical presentation was similar among both men and women. Eighty-one percent men had promiscual sexual exposure, 19% of women had so. Males were identified to be HIV-positive earlier than their spouse (tested later, time lag being 27.6 weeks. After detection of positivity 77% of females felt being less cared for by the in-laws. CD4 count less than 50 was detected in more number of females as compared to men (11% females and 1% males. Death of spouse was seen more often in females (among 35% of women and 11% of men. Conclusion: Most of the females were likely to acquire infection from their spouse. Females tend to seek and get medical attention at the late stage of disease as compared to men. HIV in females has different social implications which includes discrimination within the family.

Rural populations neighboring the Semipalatinsk nuclear test site were used as a model to develop and test an integrated population-genetic approach to analysis of the medical genetic situation and environmental conditions in the areas studied. The contributions of individual factors of population dynamics into the formation of the genetic load were also assessed. The informative values of some genetic markers were estimated. Based on these estimates, a mathematical model was constructed that makes it possible to calculate numerical scores for analysis of the genetic loads in populations differing in environmental exposure.

Full Text Available Palicourea marcgravii é considerada a principal planta tóxica de interesse pecuário no Brasil, porém, até o momento, é conhecido apenas o quadro agudo da intoxicação. Esse estudo avaliou as alterações clínico-patológicas de 10 caprinos cronicamente intoxicados por P. marcgravii. Os animais receberam, diariamente, 0,2g/kg de peso corporal da planta fresca por 6 a 38 dias. Os caprinos apresentaram como principais sinais clínicos anorexia, apatia, taquicardia, arritmia, pulso venoso jugular positivo e decúbito. Nas necropsias, os achados macroscópicos foram hidropericárdio, palidez dos rins e do miocárdio, atrofia gelatinosa da gordura cardíaca, evidenciação do padrão lobular hepático e edema pulmonar. Os principais achados microscópicos foram tumefação e vacuolização de cardiomiócitos, necrose de fibras cardíacas e infiltrado inflamatório mononuclear no miocárdio. Nos rins foi encontrada marcante degeneração hidrópico-vacuolar difusa. Os achados demonstraram nos caprinos cronicamente intoxicados, quadro clínico-patológico com características distintas do observado na forma aguda da intoxicação por P. marcgravii. Essas observações comprovam o risco para caprinos da ingestão da planta, mesmo que em pequenas doses, resultando no surgimento de quadro clínico e graves lesões ainda pouco conhecidas, e que poderiam ser confundidas com outras enfermidades.

2004-01-01

Objective: To define the clinico-pathologic characteristics and survival of young-robust patients ( 2 vs 70 mg/m 2 , P<0.001), and more cycles of chemotherapy 6 vs 4, P<0.001) were observed in the youngster group. There was no difference between the two groups in family history of cancer, cigarette smoking, weight loss, and KPS. The median survival intervals of all stages (10 months vs 12 months), and the 2-and 5-year survival rates (11.1% vs 23.1% and 3.1% vs 5.4%) were comparable (P=0.090) between them. For stage IIIb, there was a trend that young patients would give better outcome than the older ones with median survivals of 11 months to 9 months and the 2-year survivals of 3.8% to 0% (P=0.071). Conclusions: The different clinico-pathologic features of the young lung cancer patients are confirmed from that of old patients, but without any survival disparity. In order to enhance our understanding and reduce the mis-diagnosis rate, it is rational to define the lung cancer in relative young people as the youngster lung cancer, which may be beneficial to the clinical practice

Global aphasia without hemiparesis: A case series

Full Text Available Background: Global aphasia without hemiparesis (GAWH is a rare stroke syndrome characterized by the unusual dissociation of motor and language functions. Issues regarding its etio-pathogenesis, lesion sites, and recovery patterns are extensively being debated in contemporary neuroscience literature. Materials and Methods: Four patients admitted in our hospital between 2005 and 2009 with GAWH caused by ischemic stroke were studied retrospectively with emphasis on number and site of lesions, etiology, and recovery patterns. Results: The clinical findings from our subjects showed that GAWH could result from either single/multiple lesions including subcortical lesions. The recovery was rapid, although not complete. One case evolved into Wernicke′s aphasia as seen in earlier studies. Two subjects revealed evolution to transcortical sensory aphasia and one to Broca′s aphasia which is distinct from previous proposals. Two cases showed lack of clinico-anatomic correlation during recovery. Conclusions: GAWH could result from both embolic and large vessel strokes and single or multiple lesions. The recovery pattern may be variable and may show lack of clinico-anatomical correlation indicating anomalous cerebral functional reorganization, questioning the conventional teaching of language representation in the brain.

Introduction: Chronic allograft nephropathy (CAN) is a poorly understood clinico-pathological entity associated with chronic allograft loss due to immunologic and non-immunologic causes. It remains the leading cause of late allograft loss. Bone marrow derived stem cells are undifferentiated cells typically characterized by their capacity for self renewal, ability to give rise to multiple differentiated cellular population, including hematopoietic (HSCs) and mesenchymal stem cells (MSCs).

Abstract Since approximately 20 years most malignant lymphomas are classified by the recognition of clinico-pathologic entities, each with its own combination of clinical, morphologic, immunophenotypic and molecular genetic characteristics. Obviously, in many instances molecular cytogenetics is of great help for classification and in some lymphomas it is even a prerequisite. Molecular cytogenetic alterations can be detected by a large variety of techniques, ranging from conventiona...

Full Text Available INTRODUCTION AND OBJECTIVES : Anemia in Protein energy malnutrition (PEM is common and its pathogenesis is multifactorial. Since the clinico - pathological patterns are reflected by their underlying etiopathogenic factors, it is important to study the associated morbidity and mortalit y and to establish their causes for an effective management. The purpose of the present study is to determine the prevalence, patterns, clinico - pathological and morphological types of anemia in protein energy malnutrition children. The objectives of the st udy are: (1 To study the clinico - pathological and morphological patterns of anemia in PEM children of age group 6 month – 5 years. (2 To assess the resultant morbidity and mortality. (3 To determine the ideal parameter for iron deficiency anemia. METHOD S: This study was conducted on 75 clinically diagnosed Protein energy malnutrition patients of age group 6 months to 5 years. Detailed clinical history elicitation and thorough clinical examination was performed. Peripheral smears of these patients were ex amined. The complete hemogram including reticulocyte count was done. The special investigations like bone marrow study, Hb electrophoresis, iron studies and stool examination were done whenever required. RESULTS: In our study, anemia in PEM affected female population more than the males of age 36 - 47 months. Most of children had Grade III PEM and Microcytic hypochromic anemia was most prevalent. Most of the children had Iron deficiency anemia. This study also indicated that Serum iron assay and TIBC are the better indicators of iron deficiency anemia in patients with PEM and it is the investigation of choice when compared to serum ferritin as it gets falsely elevated in these patients with infections confirmed by elevated CRP level. INTERPRETATION AND CONCLUS ION: Malnutrition, Infection and Anemia show a synergistic relationship. So it necessitates prompt screening and early diagnosis through proper

MÉTODO: Os achados científicos relevantes foram descritos de acordo com a ordem cronológica de publicação e as características dos estudos, se eram pré-clínicos, relacio-nados à violência precoce como fator de risco e, finalmente, achados clínicos em pacientes portadores de transtorno de estresse pós-traumático. RESULTADOS: Foi encontrada uma literatura rica de achados a respeito de disfunções do eixo hipotálamo-pituitária-adrenal e transtorno de estresse pós-traumático. Os achados mostraram que o transtorno de estresse pós-traumático está associado a disfunções deste eixo e de estruturas cerebrais como o córtex pré-frontal, hipocampo e amídala. Os pacientes com transtorno de estresse pós-traumático apresentam um aumento da responsividade dos receptores de glicocorticóides, sugerindo que a inibição do feedback negativo tem um papel importante na fisiopatologia do quadro. Estudos pré-clínicos com modelos animais de deprivação maternal evidenciaram que, dependendo de quando o trauma ocorre, a disfunção do eixo será diferente. Os estudos clínicos mostram que o estresse precoce está relacionado ao desenvolvimento de psicopatologia durante a vida adulta. CONCLUSÕES: As disfunções do eixo hipotálamo-pituitária-adrenal relacionadas ao transtorno de estresse pós-traumático são evidências robustas e os mecanismos subjacentes a ele são cada vez mais compreendidos.OBJECTIVE: To review the literature on neurobiological findings related to hypothalamic-pituitary-adrenal axis dysfunctions associated with posttraumatic stress disorder.

MÉTODO: trata-se de estudo transversal, que consistiu na avaliação de 78 prontuários de pacientes menopausadas com queixa de sangramento, no período de janeiro de 2000 a junho de 2002 no Centro Estadual de Oncologia do Estado da Bahia, submetidas à histeroscopia com biópsia de endométrio. Os achados histeroscópicos foram classificados como benignos (miomas, pólipos, atrofia, normal e suspeitos (espessamento, hiperplasias e câncer e os achados histopatológicos como benignos (miomas, pólipos, atrofia, hiperplasia típica e malignos (hiperplasia atípica e câncer. Os resultados da histeroscopia foram comparados com os exames histopatológicos. RESULTADOS: em relação aos achados suspeitos (espessamento, hiperplasias e câncer, a sensibilidade da histeroscopia foi de 85,7% e a especificidade de 88,7%, quando comparados à histopatologia. O valor preditivo positivo foi de 42,8% e o negativo 98,4%. A razão de probabilidades do teste positivo e a razão de probabilidades do teste negativo foram respectivamente 7,6 e 0,16. A acuidade da histeroscopia foi de 88,4% e o índice kappa 0,5. CONCLUSÃO: a histeroscopia isoladamente não apresentou, no presente estudo, acurácia aceitável, reforçando o conceito de que sua principal vantagem é dirigir a biópsia, devendo sempre estar associada ao diagnóstico histopatológico.

MÉTODOS: Análise clínica e de imagem referente a 166 pacientes com lesões expansivas da órbita examinadas com o tomógrafo Somaton DR da marca Siemens de terceira geração num período de 10 anos consecutivos em Hospital Universitário de referência. RESULTADOS: Os achados clínicos mais comuns foram tumoração e proptose do globo ocular. À tomografia computadorizada, o achado típico foi de massa com baixa densidade, originando-se em seios paranasais, com destruição óssea adjacente, invasão da órbita e deslocamento do globo ocular. CONCLUSÃO: O desenvolvimento da tomografia computadorizada foi decisivo no estudo da órbita pois propicia, por meio de exame radiológico altamente especializado, imagens de incrível fidelidade anatômica revelando informações sobre o processo patológico como sua localização, sua relação com as estruturas adjacentes e sua vascularização.PURPOSE: To analyze and establish clinical-radiological findings of orbital mucocele. METHODS: Clinical analysis and image of 166 patients with expansive orbital lesions submitted to third generation Siemens Somaton DR computed tomography from February 1986 to February 1995. RESULTS: The most common clinical findings were mass and proptosis. On computed tomography, the typical finding was mass with low density, coming from paranasal sinuses presenting adjacent bone destruction and orbital invasion, with displacement of ocular globe. CONCLUSION: The development of computed tomography was an important mark in orbital studies because it allows incredible anatomic imagings, yielding information about the pathologic process like its localization and anatomic relation.

Gliosarcomas are biphasic neoplasms composed of a glioblastoma admixed to a sarcomatous component with different lines of differentiation. Histogenesis of these tumors is still discussed. Our objective is to specify clinical and pathological characteristics of this rare neoplasm and to discuss its histogenesis. Retrospective study of eight cases of gliosarcomas diagnosed between January 1998 and December 2004. Clinical, radiological, therapeutic and follow-up data were reviewed. Histological features and immunohistochemical results were also included in this review. Five patients were male, three women with a median age of 50.7 (range 31-74 years). Symptoms were dominated by intracranial hypertension and paralysis. The most common location was parietal or temporo-parietal (5 cases: 62.5%). Pathological exam including histochemical and immunohistochemical study confirmed the diagnosis of gliosarcoma in all cases. Sarcomatous component had features of fibrosarcoma in 5 cases, osteosarcoma in 2 cases and malignant fibrous histiocytoma in 1 case. All patients were treated by surgical excision (complete in five cases and partial in three cases). Adjuvant radiotherapy was received in three cases. One patient was lost on follow-up. Two patients died from postoperative. complications and the five remaining patients died with a medium follow up of 9 months (extremes: 2-24 months). Clinical, radiological and follow-up features of gliosarcomas share great similarities with glioblastomas. Histopathological, histochemical and immunohistochemical studies are helpful in accuracy diagnosis. Recent cytogenetic and molecular data support a monoclonal origin for these tumors.

Conclusion: Early diagnosis and intensive medical and surgical treatment were mandatory to minimize both morbidity and mortality from NEC. Surgical management should be determined according to the special circumstances of each case. However, the optimum choice between peritoneal drainage and laparotomy remains controversial. Gestational age, birth weight, age at admission, and treatment modality are definite prognostic factors as regard morbidity and mortality of patients with NEC.

Background: To study the patterns of clinically benign breast disease in females and to co-relate them with the pathological findings. Methods: One hundred females who attended the Surgery Outpatients Department in Indira Gandhi Medical College and Research Institute, Pondicherry, with various forms of benign breast diseases during the period from October 2011 to September 2012, were studied. Early diagnoses by doing a triple assessment like a clinical examination, FNAC or a core needle biopsy and imaging methods like ultrasonography or mammography, were made within 72 hrs from the first consultation. The clinical diagnoses were compared with the cytological or histological findings wherever possible and their accuracies were evaluated. Results: Out of the 100 female patients who were studied, 87 patients who presented with breast lumps and fibroadenoma, accounted for 48% of the cases, which was the highest number of patients. Fibrocystic changes and breast abscesses came next with 18% and 12% cases respectively. We detected 3 cases of proliferative disease with atypia and one case with florid hyperplasia, which had high and low risk factors respectively, for developing invasive carcinoma. The oldest lady of the group who was clinically diagnosed to have benign disease, was detected to have invasive ductal carcinoma. They were treated in our hospital and were advised follow up. Conclusion: Benign breast diseases are common in female patients and fibroadenoma is the commonest of them all. Triple assessment provided a quick diagnosis and it alleviated unnecessary anxiety from the patients about breast cancer. The clinical diagnosis of a breast lump, as confirmed by cytology and histology, was accurate in 91.95 % of the cases. PMID:23634406

Full Text Available We report clinical, radiological, and pathological features of three cases of macrodystrophia lipomatosa, which is characterized by progressive proliferation of all mesenchymal elements, with a disproportionate increase in fibroadipose tissue. The peculiarity in our report is the involvement of contralateral hand and feet in our 1st case in contrast to usual presentations of this rare condition, which is often unilateral. In our 2nd case, the lateral aspect of foot was involved as against the usual finding of involvement of medial aspect in lower limbs, also another surprising finding in this case is increase in the size of lesion after puberty.

Full Text Available Ten-bitches and 8-male dogs afflicted with transmissible venereal tumour (TVT randomly divided into 3 groups viz. Group-I, Group-II and Group-III comprising 6 dogs each, were subjected to three different protocols. Group-I was treated surgically. A complete regression of the tumour mass was observed in 4 (66.67% dogs, while 2 (33.34% had incomplete regression at the end of first 5 weeks. A 16.67% recurrence rate was also observed at the end of 6 months study period. In Group-III, chemotherapy with intravenous injection of vincristine sulphate @ 0.025 mg/kg b.wt. affected 80.33% (n=5 complete regression whereas incomplete regression was recorded in only one (16.67% subject at the end of 5th week. Vomiting and inappetance as side-effects were also noticed. Group-III was subjected to a combination of surgery and chemotherapy where vincristine sulphate was used after surgical debulking of tumour mass. A 100% regression even after 2-3 injections with no recurrence was achieved till 6 months post-treatment. There was a significant increase (P≤0.01 in erythrocyte sedimentation rate and total leukocyte count (TLC in TVT -afflicted dogs which returned to normal after 2-5 weeks of treatment. Vincristine sulphate had a significant decreasing effect on TLC in both Group-II and Group-III, which was transient.

Endoscopic management of Atypical sellar cavernous hemangioma: A case report and review of the literature

Directory of Open Access Journals (Sweden)

A.M. Al-Sharydah

2018-01-01

Conclusion: Seller cavernous hemangioma (SCH is an extremely rare lesion that can be misdiagnosed. It is characterized by clinico-radiological features similar to those of other lesions such as pituitary macroadenoma and should be included in the differential diagnosis. The endoscopic endonasal transsphenoidal (EET approach with subtotal/total resection appears to be a feasible option for debulking, with less surgical complications. Nonetheless, combining stereotactic radiosurgery will reduce postsurgical morbidities.

Distributed research networks (DRNs) afford statistical power by integrating observational data from multiple partners for retrospective studies. However, laboratory test results across care sites are derived using different assays from varying patient populations, making it difficult to simply combine data for analysis. Additionally, existing normalization methods are not suitable for retrospective studies. We normalized laboratory results from different data sources by adjusting for heterogeneous clinico-epidemiologic characteristics of the data and called this the subgroup-adjusted normalization (SAN) method. Subgroup-adjusted normalization renders the means and standard deviations of distributions identical under population structure-adjusted conditions. To evaluate its performance, we compared SAN with existing methods for simulated and real datasets consisting of blood urea nitrogen, serum creatinine, hematocrit, hemoglobin, serum potassium, and total bilirubin. Various clinico-epidemiologic characteristics can be applied together in SAN. For simplicity of comparison, age and gender were used to adjust population heterogeneity in this study. In simulations, SAN had the lowest standardized difference in means (SDM) and Kolmogorov-Smirnov values for all tests (p normalization performed better than normalization using other methods. The SAN method is applicable in a DRN environment and should facilitate analysis of data integrated across DRN partners for retrospective observational studies.

Primary epiploic appendagitis: US and CT findings

International Nuclear Information System (INIS)

Molla, E.; Ripolles, T.; Martinez, M.J.; Morote, V.; Rosello-Sastre, E.

1998-01-01

A retrospective review is presented of seven cases of epiploic appendagitis, with surgical confirmation in one case. The main clinico-analytical data and the US and CT findings are described, as well as the histopathologic features in the sole case that underwent surgical resection. We also calculated the frequency of this entity in patients undergoing emergency abdominal US on clinical suspicion of diverticulitis. In all seven cases the clinico-analytical evidence was nonspecific (localized acute abdominal pain and slight leukocytosis), mimicking in six cases the clinical presentation of sigmoid diverticulitis and in one case that of acute appendicitis. US imaging findings were characteristic: a hyperechoic mass localized under the point of maximum pain, adjacent to the anterior peritoneal wall and fixed during deep breathing. In none of the cases did color Doppler US show flow. CT findings were also typical and showed a mass with a peripheral hyperattenuated rim surrounding an area of fatty attenuation. Overall 7.1 % of patients investigated to exclude sigmoid diverticulitis finally showed findings of primary epiploic appendagitis. Primary epiploic appendagitis thus shows characteristic US and CT findings that allow its diagnosis and follow-up. This entity is much more frequent than previously reported, especially in patients referred for US to exclude sigmoid diverticulitis. (orig.)

2013-07-01

Full Text Available Clinical, pathoanatomical, histological, and bacteriological studies were performed on broiler chickens, growing broiler parents, and growing egg layers, in three different poultry farms, after an outbreak of Pseudomonas aeruginosa infections. The method of contamination of the birds was established. Several local and systemic clinico-morphological forms of spontaneous P. aeruginosa infections in various categories of stock birds were described: cases of P. aeruginosa infection resulting from injection of contaminated vaccines; case of P. aeruginosa infections through contaminated aerosol vaccine and cases of pododermatitis, periarthritis and arthritis in broiler chickens associated with P. aeruginosa infection. In different cases mortality range between 0.5 and 50%. The results showed that apart from embryonic mortality in hatcheries, and septicemic infections in newly hatched chickens, the pathogenicity of P. aeruginosa was associated with localized and systemic lesions in this category, as well as in young and growing birds. On one hand, these results have a theoretical significance, contributing for the confirmation and expansion of the wide array of clinico-morphological forms of P. aeruginosa infections in birds. On the other hand, the knowledge on these forms has a purely practical significance in the diagnostics of P. aeruginosa infections by poultry pathologists and veterinary practitioners.

Heterogeneity of Mesenchymal Markers Expression—Molecular Profiles of Cancer Cells Disseminated by Lymphatic and Hematogenous Routes in Breast Cancer

Breast cancers can metastasize via hematogenous and lymphatic routes, however in some patients only one type of metastases are detected, suggesting a certain proclivity in metastatic patterns. Since epithelial-mesenchymal transition (EMT) plays an important role in cancer dissemination it would be worthwhile to find if a specific profile of EMT gene expression exists that is related to either lymphatic or hematogenous dissemination. Our study aimed at evaluating gene expression profile of EMT-related markers in primary tumors (PT) and correlated them with the pattern of metastatic spread. From 99 early breast cancer patients peripheral blood samples (N = 99), matched PT (N = 47) and lymph node metastases (LNM; N = 22) were collected. Expression of TWIST1, SNAI1, SNAI2 and VIM was analyzed in those samples. Additionally expression of CK19, MGB1 and HER2 was measured in CTCs-enriched blood fractions (CTCs-EBF). Results were correlated with each other and with clinico-pathological data of the patients. Results show that the mesenchymal phenotype of CTCs-EBF correlated with poor clinico-pathological characteristics of the patients. Additionally, PT shared more similarities with LNM than with CTCs-EBF. Nevertheless, LNM showed increased expression of EMT-related markers than PT; and EMT itself in PT did not seem to be necessary for lymphatic dissemination

A lactate shuttle system between tumour and stromal cells is associated with poor prognosis in prostate cancer

Pértega-Gomes, Nelma; Vizcaíno, José R; Attig, Jan; Jurmeister, Sarah; Lopes, Carlos; Baltazar, Fátima

2014-01-01

In a malignant tumour, cancer cells are embedded in stromal cells, namely cancer-associated fibroblasts (CAFs). These CAFs are now accepted as important players in cancer dynamics, being involved in tumour growth and progression. Although there are various reports on the interaction between tumour and stromal cells, the clinico-pathological significance of this cross-talk is still largely unknown. In this study, we aimed to characterise the expression of key metabolic proteins involved in glucose transport, pyruvate/lactate shuttle system, glycolytic metabolism and fatty acid oxidation in CAFs and tumour cells in different stages of malignant transformation. We further aimed to contextualise the clinico-pathological significance of these protein expression profiles with reference to known prognostic indicators, including biochemical recurrence in pT stage. Prostate tissues were obtained from 480 patients with a median age of 64 years following radical prostatectomy with no previous hormonal therapy. Tissues were analysed for the expression of several key metabolism-related proteins in glands and surrounding fibroblasts by immunohistochemistry. Reliable markers of prognosis such as pT stage and biochemical recurrence were assessed for each case. We observed that prostate cancer cells did not rely mainly on glycolytic metabolism, while there was a high expression of MCT4 and CAIX - in CAFs. This corroborates the hypothesis of the “Reverse Warburg effect” in prostate cancer, in which fibroblasts are under oxidative stress and express CAIX, an established hypoxia marker. We found that alterations in the expression of metabolism-related proteins were already evident in the early stages of malignant transformation, suggesting the continuing alteration of CAFs from an early stage. Additionally, and for the first time, we show that cases showing high MCT4 expression in CAFs with concomitant strong MCT1 expression in prostate cancer (PCa) cells are associated with poor

Full Text Available O entendimento da interação de nanotubos de carbonos e fulerenos com os constituintes da pele, em especial o sistema imune de pele, é relevante para a determinação de parâmetros toxicológicos. Realizou-se revisão voltada a tais aspectos. Parte considerável das referências encontradas concentrou-se nos efeitos citotóxicos e de permeação da pele. Em menor escala, há artigos sobre ativação e imunomodulação de células e outros elementos imunes. Poucos trabalhos encontrados tratam, especificamente, da resposta imunológica cutânea, limitando o conhecimento relacionado. Os achados sugerem que os nanomateriais analisados possam estar envolvidos em quadros dermatológicos, como dermatite de contato irritativa, reações anafilactoides, urticária e angioedema, e suscitam a necessidade de que se realizem estudos adicionais para confirmação dos achados. A padronização da descrição e testagem de características dos nanomateriais empregados em experimentos pode facilitar a comparação dos resultados.

Cancer of unknown primary origin (CUP) is one of the ten most frequent cancers worldwide. It constitutes of 3-5% of all human malignancies. At time of diagnosis patients with CUP present with disseminated metastases without established primary origin. CUP manifests as heterogenous group of mainly epithelial cancers recognised by distinct clinico pathological entities. The diagnostic work-up includes extensive histopathology investigations and modern imaging technology. Nevertheless, the primary tumour remains undetected most of the time. (author)

Full Text Available RESUMO A infecção em cães por Dioctophyma renale, relatada em diversas partes do mundo, é considerada incomum, na maioria das vezes. No entanto, em algumas regiões são descritos números crescentes da infecção e muitos dados da epidemiologia e do ciclo biológico do parasito ainda são obscuros. Dessa forma, o trabalho tem como objetivo descrever os aspectos epidemiológicos, clinicopatológicos e ultrassonográficos de casos de infecção por Dioctophyma renale em cães na região da Fronteira Oeste do Rio Grande do Sul. Foram estudados 28 casos de dioctofimose em cães necropsiados ou clinicamente avaliados, submetidos à ultrassonografia e cirurgia para retirada dos parasitos. Os cães errantes foram os mais acometidos e todos com possível acesso às margens do Rio Uruguai. As lesões renais e extrarrenais foram caracterizadas predominantemente por atrofia do parênquima renal com glomerulonefrite esclerosante e peritonite granulomatosa associada a parasitos adultos livres na cavidade abdominal e ovos, bem como migrações erráticas para o tecido subcutâneo. Por fim, os achados ultrassonográficos corresponderam, especialmente, a imagens transversais circulares de até 0,6 cm de diâmetro, com margem hiperecoica e centro hipoecoico. Esses achados foram patognomônicos para infecção por Dioctophyma renale, e o exame ultrassonográfico se mostrou indispensável para o diagnóstico definitivo durante a avaliação clínica. Os achados observados nesse estudo demonstram a importância dessa parasitose na região. Além disso, alertam para a importância do diagnóstico, que vem sendo subestimado, além de apontar a necessidade de mais dados acerca da epidemiologia da doença para que se chegue a métodos efetivos de controle.

Full Text Available Aim: The purpose of this study was to compare the electrocardiographic (ECG, hematological and clinico-biochemical effects of two balanced anesthetic protocols in dogs. Materials and Methods: A total of 20 clinical cases of dogs, randomly divided into two groups of 10 animals each were made part of study. All dogs were premedicated with injection atropine sulfate @ 0.04 mg/kg body weight (b. wt. subcutaneously followed 15 min later with injection butorphanol tartarate @ 0.2 mg/kg b. wt. intravenous (IV. Subsequently after 10 min premedicated with injection diazepam @ 0.5 mg/kg b. wt. IV (Group DP or injection acepromazine maleate @ 0.015 mg/kg b. wt. IV (Group AP followed by injection propofol “till effect” IV for induction of surgical anesthesia. The animals were immediately transferred to halothane in oxygen. Observations recorded in dogs included ECG recordings, hematological and clinico-biochemical observations at various time intervals. Results: No arrhythmia was observed in any animal pre-operatively and intra-operatively in any of the groups. Significant fall in packed cell volume (PCV and total erythrocyte count occurred in DP group in early phase, whereas only PCV decreased significantly in AP group. Biochemical parameters were non-significant in both the groups. Conclusion: Both diazepam-butorphanol-propofol-halothane and acepromazine-butorphanol-propofol-halothane are safe with respect to their ECG, hematological and biochemical effects in clinical cases.

The clinical spectrum of germline mismatch repair (MMR) gene variants continues increasing, encompassing Lynch syndrome, Constitutional MMR Deficiency (CMMRD), and the recently reported MSH3-associated polyposis. Genetic diagnosis of these hereditary cancer syndromes is often hampered by the presence of variants of unknown significance (VUS) and overlapping phenotypes. Two PMS2 VUS, c.2149G>A (p.V717M) and c.2444C>T (p.S815L), were identified in trans in one individual diagnosed with early-onset colorectal cancer (CRC) who belonged to a family fulfilling clinical criteria for hereditary cancer. Clinico-pathological data, multifactorial likelihood calculations and functional analyses were used to refine their clinical significance. Likelihood analysis based on cosegregation and tumor data classified the c.2444C>T variant as pathogenic, which was supported by impaired MMR activity associated with diminished protein expression in functional assays. Conversely, the c.2149G>A variant displayed MMR proficiency and protein stability. These results, in addition to the conserved PMS2 expression in normal tissues and the absence of germline microsatellite instability (gMSI) in the biallelic carrier ruled out a CMMRD diagnosis. The use of comprehensive strategies, including functional and clinico-pathological information, is mandatory to improve the clinical interpretation of naturally occurring MMR variants. This is critical for appropriate clinical management of cancer syndromes associated to MMR gene mutations.

Full Text Available Abstract Aims As one of the five Lactate dehydrogenase (LDH isoenzymes, LDH5 has the highest efficiency to catalyze pyruvate transformation to lactate. LDH5 overexpression in cancer cells induces an upregulated glycolytic metabolism and reduced dependence on the presence of oxygen. Here we analyzed LDH5 protein expression in a well characterized large cohort of primary lung cancers in correlation to clinico-pathological data and its possible impact on patient survival. Methods Primary lung cancers (n = 269 and non neoplastic lung tissue (n = 35 were tested for LDH5 expression by immunohistochemistry using a polyclonal LDH5 antibody (ab53010. The results of LDH5 expression were correlated to clinico-pathological data as well as to patient's survival. In addition, the results of the previously tested Transketolase like 1 protein (TKTL1 expression were correlated to LDH5 expression. Results 89.5% (n = 238 of NSCLC revealed LDH5 expression whereas LDH5 expression was not detected in non neoplastic lung tissues (n = 34 (p Conclusions LDH5 is overexpressed in NSCLC and could hence serve as an additional marker for malignancy. Furthermore, LDH5 correlates positively with the prognostic marker TKTL1. Our results confirm a close link between the two metabolic enzymes and indicate an alteration in the glucose metabolism in the process of malignant transformation.

2017-11-01

Contemporary potentially malignant disorder management is based upon provisional histological diagnosis followed by interventional surgery to excise or ablate 'high-risk' mucosal lesions. Although the majority of patients achieve disease-free status post-treatment, others develop further or persistent disease unresponsive to intervention. A detailed, retrospective clinico-pathological review of treatment resistant potentially malignant lesions, from a 590 patient cohort treated by CO 2 laser surgery and followed for a mean of 7.3 years, was undertaken. Clinical outcome was determined at study census date (31 December 2014). A total of 87 patients (15%) exhibited PMD disease resistant to treatment: 34 (6%) became disease free following further treatment, whilst 53 (9%) had persistent disease despite intervention. Disease-free patients were younger, changed lesion appearance from erythroleukoplakia to leukoplakia (P = .004), developed further lesions at new sites, demonstrated reduction in dysplasia severity with time and required multiple treatments to achieve disease-free status (P = .0005). In contrast, persistent disease patients were older, male, often presented with proliferative verrucous leukoplakia (PVL) on gingival and alveolar sites, displayed less severe dysplasia initially and underwent laser ablation rather than excision (P = .027). Despite clinico-pathological profiling of treatment resistant patients, the precise inter-relationship between the inherent nature of potentially malignant disease and the external influence of treatment intervention remains obscure. © 2017 John Wiley & Sons A/S.

To evaluate the prognostic value of metabolic activity of metastatic lesions measured by 18 F-flurodeoxyglucose ( 18 F-FDG) uptake on preoperative positron emission tomography/computed tomography (PET/CT) in patients with advanced serous epithelial ovarian cancer (EOC). Clinico-pathological variables and PET/CT parameters such as the maximum standardised uptake value of the ovarian cancer (SUV ovary ), metastatic lesions (SUV meta ), and the metastatic lesion-to-ovarian cancer standardised uptake value ratio (SUV meta /SUV ovary ) were assessed in International Federation of Gynaecology and Obstetrics (FIGO) stage III, IV patients. Clinico-pathological data were retrospectively reviewed for 94 eligible patients. The median progression-free survival (PFS) was 18.5 months (range, 6-90 months), and 57 (60.6%) patients experienced recurrence. Older age [P = 0.017, hazard ratio (HR) 1.036, 95% CI 1.006-1.066], residual disease after surgery (P = 0.024, HR 1.907, 95% CI 1.087-3.346), and high SUV meta /SUV ovary (P = 0.019, HR 2.321, 95% CI 1.148-4.692) were independent risk factors of recurrence. Patients with high SUV meta /SUV ovary showed a significantly worse PFS than those with low SUV meta /SUV ovary (P = 0.007, log-rank test). Preoperative SUV meta /SUV ovary was significantly associated with recurrence and has an incremental prognostic value for PFS in patients with advanced serous EOC. (orig.)

AIM: To audit the relationship between Cancer Centre oncologists visiting peripheral hospitals and peripheral hospital radiologists by assessing (i) oncologists' knowledge of local radiological services; (ii) oncologists' perceptions of peripheral radiological services; (iii) peripheral radiologist's perceptions of oncologists; (iv) barriers to communication. MATERIALS AND METHODS: A postal questionnaire was sent to all radiology departments visited by an oncologist, and to all medical and clinical oncologists from two regional oncology centres. RESULTS: The response rate was 100% (21 peripheral hospital radiology departments and all 35 oncologists). (i) Oncologists' knowledge of peripheral hospital imaging modalities was limited (especially MRI and intervention). (ii) 72% of oncologists rated the peripheral hospital radiology service as excellent or good, 46% rated the radiology report quality excellent to good. Deficiencies in oncological reports were identified. (iii) 44% of radiologists thought the oncologist did not relate well with the local radiology department. 50% of radiologists did not know the visiting oncologist's specialist interest. (iv) 69% of oncologists did not regularly attend peripheral hospital clinico-radiological meetings. Lack of written and oral information was hampering both specialities. CONCLUSION: Communication between oncologists and the local radiology department should include: (1) information about local radiology services for visiting oncologists (including trainees) and on the oncology team for radiologists; (2) standardized report content; (3) improved clinical information for radiologists; (4) regular clinico-radiological meetings.

2003-01-01

Retrospective clinical analysis with a special focus on pyramidal syndrome expression in the disease course as well as morphological study of brain and spinal structures in all levels of cortical-spinal projection (from brain motor cortex to spinal lumbar segments) have been conducted for 11 section cases of lateral amyotrophic sclerosis (LAS), sporadic type. Two groups of patients were studied: with pronounced pyramidal syndrome (spasticity, hyperreflexia, etc)--7 cases and with some signs of pyramidal deficiency (anisoreflexia, stability of peritoneal reflexes)--4 cases. Pyramidal syndrome in LAS is considered as an emergence of current neurodegenerative process, embracing a significant part of upper motor neurons of both precentral convolution and its axons along the whole length of cerebrospinal axis in the form of cytoplasmic inclusions and axonal spheroids. A presence of pathomorphological changes in other upper segmental structures of motor control reveals their role in pyramidal deficiency. Comparative analysis showed that expression of pyramidal syndrome signs and its correlation to atrophic paresis appearances is specifically determined by the severity of upper and lower motor neurons lesions. With regard to morphological changes in CNS structures, the peculiarities of some pyramidal syndrome appearances in LAS are analyzed.

Full Text Available Background: Oral submucous fibrosis (OSF is a precancerous condition associated with the use of areca nut in various forms. There are very few reports to correlate the clinical stage to histopathological grading in OSF. Materials and Methods: A hospital-based study was conducted on 75 OSF cases who visited our hospital in Chennai from 2000-2003. A detailed history of each patient was recorded along with a clinical examination. Biopsy was performed for histopathological correlation. Clinical stage of the disease in terms of the ability to open one′s mouth was correlated with histopathological grading. Results: The male to female ratio of OSF cases was 6:1. All forms of areca nut products were associated with OSF. Chewing of paanmasala was associated with early presentation of OSF as compared to chewing of the betel nut. Out of 57 cases, which were in clinical stage II, 91.2% had histological grading of I and II in equal proportions and 8.8% had histological grade III. Out of 13 cases that showed a clinical stage of III, 52% showed a histological grade of II, 40% grade III and 8% grade I. Conclusion: In the present study, there was no direct correlation between clinical stages and histopathological grading. The possibility of difference in the severity and extent of fibrosis in different regions of the oral mucosa and involved muscles were considered as contributory factors for this variation.

1979-01-01

The mechanism of reparative processes under the effect of various drugs was studied in experimental acute radiation ulcer of rats. It was established that at the stage of marked exudative-necrotic processes the use of antiinflammatory and antiexudative substances (bariz, dimethylsulfoxyde) led to normalization of the microcirculation that reduced the time of radiation ulcer healing. The use of anabolic steroids (retabolil) intensified metabolism that also produced a favourable effect on the reparative processes

GOT, GPT, LDH, total Ac-P, prostatic Ac-P, cholesterol, free fatty acid, Ca, and P in plasma were measured once a week on rabbits injected subcutaneously with 0.5 and 1.0 mg Cd/kg daily for 11 weeks respectively, and Cd, Cu, Mn, and Zn contents in organs were determined at the termination of the experiment. Prostatic Ac-P activity, cholesterol, and free fatty acid levels in plasma rose in the early stage of administration, and GOT, GPT, LDH, and Al-P activities rose in the latter stage of administration. Ca and P levels in plasma did not change in any periods of the experiment. From these results, it could be concluded that a measurement of prostatic Ac-P, cholesterol, and free fatty acid is adequate to evaluate excess intake of Cd. Cd contents in heart, lungs, spleen, and testes of rabbits injected with 1.0 mg Cd/kg increased significantly compared with those with 0.5 mg Cd/kg, but a difference between the two groups in Cd contents in liver, kidneys and submandibular glands which contained high concentration of Cd was not recognized. Zn contents in organs of rabbits injected with Cd increased remarkably, while Cu contents decreased generally. This phenomenon was especially remarkable in liver and kidneys. 31 references, 7 figures, 2 tables.

From 5,625 biopsies received and analyzed, a total of 461 (8.2%) were non-neoplastic enlargement of the salivary glands; for each case, we registered demographic data as well as clinic characteristics. These lesions were characterized as a heterogeneous group of pathologic entities among which we included local, obstructive, infectious, and immunopathologic lesions. The most frequent lesion was the extravasation cyst in 341 (74%) cases, followed by chronic sialoadenitis and Sjögren's syndrome with 54 (11.7%) and 41 (8.8%) cases, respectively, and at a lesser percentage mucous retention cyst, sialosis, benign lymphoepithelial lesions and those related with sialolytes. Females were affected more frequently; mean age was second to third life decades. These lesions were most frequently localized on inferior labial mucosa.

Full Text Available INTRODUCTION : A polypoidal mass in the nasal cavity is a condition commonly encountered by the Otorhinolaryngologist. A diverse group of lesions may present themselves as polypoidal masses. A number of benign looking polyps often turn out to be malignant lesions or vice versa. OBJE CTIVES : This study is intended to clinically differentiate the various conditions presenting as nasal polypoidal lesions , to understand their exact nature by histopathological examination and thereby learn the relative incidence of individual conditions en countered. METHODOLOGY : D etailed history , clinical examination and histopathological examination of nasal polypoid masses were done in 73 patients. Incidence , clinical features and histopathological correlation of all the polypoidal masses were ascertained. RESULTS : O f the 73 cases , 53 (72.6% cases were non - neoplastic and 20 (27.4% were neoplastic lesions. The non - neoplastic lesions included nasal polyps , rhinosporidiosis , pyogenic granuloma and mucocoele. Benign neoplasms included inverted papilloma , haemangioma , angiofibroma , neurilemmoma and pleomorphic adenoma. Malignant neoplasms included squamous cell carcinoma , adenoid cystic carcinoma and olfactory neuroblastoma. CONCLUSION : P olypoidal masses in the nose may range from non - n eoplastic lesions to benign and malignant neoplasms with various histopathologic findings. It is impossible to distinguish between such lesions clinically. Hence , it is essential that all polypoidal masses removed should be evaluated histopathologically , t o make a correct diagnosis.

Esheba, Gh.E.; Esheba, N.E.

2013-01-01

Overview: Although angiomyolipoma (AML) is a relatively rare entity, it is the most common benign mesenchymal neoplasm of the kidney. The aim of this study: To highlight the clinicopathological characteristics of AML and to assess the role of Human Melanoma Black-45 (HMB-45), Melan-A, smooth muscle actin (SMA), S-100 and cytokeratin in its diagnosis. Materials and methods: The study included 15 cases of AML. Clinical and radiological data were retrieved from the archival files and all cases were subjected to a histopathological evaluation as well as immunohistochemical staining for HMB-45, Melan-A, SMA, S-100, and cytokeratin. Results: AML was more common in females (female:male = 4:1), the mean age was 53.9 ± 6.45 years. 60% of patients were symptomatic while the remaining 40% were asymptomatic. A statistically significant relationship was found between size of the tumor and the presence of the symptoms (P = 0.02). Patients with tumor size less than 4 cm were asymptomatic, while those with tumor size larger than 4 cm had different symptoms. Thirteen cases were classic AML, while 2 cases were epithelioid AML. Classic AML demonstrated admixture of fatty tissue, thick-walled blood vessels, and smooth muscle, while epithelioid AML was composed mainly of epithelioid cells and contained no fat. HMB-45 was positive in all cases of AML (100%), Melan-A was positive in 13/15 (87%) while SMA was positive in 11/15 (73%) of AML with variable staining intensity. All cases of AML were negative for S-100 and cytokeratin. Conclusion: AMLs have characteristic clinicopathological and immunohistochemical features and their recognition is crucial for proper diagnosis and treatment

1989-01-01

During diagnostic esophagogastroduodenoscopy, 104 children aged 6 months to 14 years were subjected to spot biopsy of the mucous membrane of the antral part of the stomach and duodenal bulb with a purpose of subsequent studies for Campylobacter pyloris (C. P.) including primary microscopy, the screening-urease test and culture isolation followed by its identification according to all the necessary biochemical tests. C. P. were detected in 50% of the children examined including 9 out of 12 patients suffering from ulcer disease of the duodenum. It was shown that the C. P. incidence noticeably rose with an increase of the period of the gastroenterologic anamnesis. The characteristic clinical and endoscopic signs of the illness were defined, associated with most or less probable C. P. isolation. It has been established that the findings of the screening-urease test cannot form the basis for the final diagnosis of pyloric campylobacteriosis in children.

1988-01-01

The relation between neurological signs and symptoms and computed tomography (CT) and magnetic resonance imaging (MRI) was examined in 11 cases of occlusion of the left posterior cerebral artery. All the patients were righthanded. Right homonimous hemianopia was noted in 8 cases, right upper quadrantanopia in 2 cases, and right lower quadrantanopia in 1 case. Of the 11 cases, alexia without agraphia was noted in 9 cases, all 9 of which showed lesions of inferior occipital cortex (lingual and fusiform gyri) and subjacent white matter. Lesions of splenium were found in only 5 of the cases of alexia without agraphia. In 2 cases with neither alexia nor agraphia, lesions were seen in the medial occipital cortex and the subjacent white matter but not in the inferior occipital lobe. Three patients had color anomia which was accompanied by memory disturbances and alexia without agraphia. In 2 of these 3, lesions were widespread in the region of the left posterior cerebral artery. Memory disturbances were observed in 6 cases, all of which also showed alexia without agraphia. The lesions extended not only of the inferior surface of the occipital lobe and along the interhemispheric fissure, but also of hippocampal and parahippocampal gyri. In 3 cases of alexia without agraphia in which no memory distrubance was found, the symptoms of alexia were slight and disappeared at an early stage. (J.P.N.)

Chamakuri

2015-10-01

Full Text Available INTRODUCTION: Anemia is defined as haemoglobin level in the blood below the lower extreme of the normal range for the age and sex of the individual. According to WHO, in developing countries the prevalence of anemia among pregnant women averages 60%, ranging between 35 to 100% among different regions of the world. A hemoglobin concentration below 11.0g/dl or packed cell volume (PCV of less than 33.0% is regarded as anemia during pregnancy by the WHO. It occurs in 40 - 80% of the pregnant women. Iron and folic acid defici encies, malaria, intestinal parasitic infections and hemoglobinopathies are the principal causes of anemia in pregnancy. Predisposing factors include young age, grand multiparity, low socioeconomic status, illiteracy, ignorance and short intervals of pregn ancy. AIM AND OBJECTIVES: 1. To study various patterns of anemia in pregnant women having haemoglobin level < 11 gm%. 2. To determine the most common pattern of anemia in pregnancy based on red cell morphology. MATERIALS AND METHODS: This study is a prospe ctive study over a period of one year from September 2014 to August 2015 in the department of pathology, Andhra medical college, Visakhapatnam . The study was conducted on 120 pregnant women whose haemoglobin level is < 11 gm/dl. All the haemotological parameters & peripheral blood smear stained by Leishman’s stain were evaluated. Complete clinical & obstetric history was recorded. Socioeconomic status was also noted. RESULTS: Out of 120 cases of anemia, we found 47 patie nts (39.1% having dimorphic anemia, 36(30% – microcytic hypochromic anemia, 23(19.1% - normocytic hypochromic anemia, 11(9.16% - sickle cell anemia and 1(0.83% case of pancytopenia. Maximum cases were seen in the age group of 21 - 30 years. 52 cases (43. 3% were primigravida and remaining 68 cases (56.6% were gravida two to four. 20 cases (16.6% were diagnosed in the first trimester, 38 cases (31.6% in the second trimester & 62 cases (51.6s% in the third trimester. CONCLUSION: In conclusion, the commo n morphological patterns of anemia in this study are dimorphic anemia and microcytic hypochromic anemia. More common in the multigravida & in the third trimester of pregnancy. After the 1 st trimester there is increased fetal demand & hemodilution effect an d thus anemia occurs commonly in this period. The risk factors for anemia in this study are low socioeconomic status, multiparity & H/O complications during previous pregnancy. The socioeconomic conditions must be improved, early detection & good antenatal care to be provided for the prevention of anemia in pregnancy

Full Text Available FUNDAMENTOS: A capilaroscopia é método não invasivo e reprodutível capaz de analisar diretamente os capilares na região periungueal, auxiliando no diagnóstico diferencial das doenças do tecido conectivo. OBJETIVOS: Estudar, por meio da capilaroscopia periungueal, pacientes com lúpus eritematoso cutâneo crônico, lúpus eritematoso sistêmico e grupo controle. MÉTODOS: Foram analisados 70 pacientes pela capilaroscopia periungueal, sendo 37 com lúpus eritematoso cutâneo crônico e 33 com forma sistêmica, comparados a 32 indivíduos sadios. RESULTADOS: A presença de capilares ectasiados (p=0,027; p=0,001, enovelados (p=0,001; p=0,007 e em saca-rolhas (p=0,011;p=0,005, além de hemorragias capilares (p=0,004; p=0,001 foram parâmetros capazes de discriminar os dois grupos de pacientes do grupo controle. A variável capilar enovelado demonstrou ser preditiva para o diagnóstico de lúpus eritematoso sistêmico (OR=8,308. As variáveis independentes capilares ectasiados (OR=12,164 e hemorragias capilares (OR=5,652 foram preditoras para lúpus eritematoso cutâneo crônico. CONCLUSÃO: A capilaroscopia é útil na prática clínica, pois pacientes com alterações capilaroscópicas específicas parecem ter maior probabilidade de desenvolver lúpus eritematoso. As variáveis preditoras independentes para lúpus eritematoso sistêmico foram capilares enovelados e para lúpus eritematoso cutâneo crônico foram capilares ectasiados e hemorragias capilares.BACKGROUND: Capillaroscopy is an useful diagnostic tool that is non-invasive, reproducible, able to assess the capillaries in the periungal region and that assists in the differential diagnosis of connective tissue diseases. OBJETIVES: The aim of the study was to distinguish chronic cutaneous lupus erythematosus and systemic lupus erythematosus from controls assessed by nailfold capillaroscopy. METHODS: Seventy patients with lupus erythematosus (37 with chronic cutaneous lupus erythematosus and 33 with systemic lupus erythematosus were studied by the technique of capillary microscopy and compared to 32 controls. RESULTS: The presence of ectatic (p=0.027; p=0.001, meandering (p=0.001; p=0.007, corkscrew capillaries (p=0.011; p=0.005 and nailfold bleeding (p=0.004; p=0.001 distinguished between the two groups of patients (chronic cutaneous lupus erythematosus and systemic lupus erythematosus from controls. The variable meandering loops could be predictive for systemic lupus erythematosus (OR=8.308. The independent variables ectatic loops (OR=12.164 end nailfold bleedings (OR=5.652 were predictive for chronic cutaneous lupus erythematosus. CONCLUSIONS: Capillaroscopy can help in the management of patients, since the presence of typical capillaroscopic abnormalities seems to be related to the development of lupus erythematosus. The independent predictive variables for systemic lupus erythematosus were meandering loops, and, for chronic cutaneous lupus erythematosus, ectasic loops and nailfold bleedings.

Full Text Available Neste trabalho são descritos os aspectos tomográficos de alta resolução dos linfomas pulmonares e feita correlação com os achados anatomopatológicos. Com este objetivo, foram revisados as tomografias computadorizadas de alta resolução do tórax e os dados histopatológicos de dez pacientes com diagnóstico confirmado de linfoma não-Hodgkin ou de doença de Hodgkin. Os resultados obtidos foram confrontados com os descritos na literatura. Os achados radiológicos mais comumente vistos neste estudo foram as consolidações parenquimatosas, localizadas, com broncogramas aéreos de permeio (n = 8. Em menor freqüência, foram encontrados múltiplos nódulos parenquimatosos (n = 4, espessamento peribroncovascular (n = 3 e opacidades em vidro fosco (n = 2. Na correlação com a anatomia patológica, as consolidações corresponderam a preenchimento alveolar por células neoplásicas, o espessamento peribroncovascular se deveu a infiltração das bainhas peribroncovasculares por células linfomatosas e a atenuação em vidro fosco se associou com infiltração dos septos alveolares por tais células.

Full Text Available Este trabalho tem como objetivo revisar as patologias que acometem o compartimento iliopsoas. Foi realizada análise retrospectiva de casos com acometimento do compartimento iliopsoas avaliados por tomografia computadorizada (TC, no Departamento de Radiologia da Faculdade de Ciências Médicas da Universidade Estadual de Campinas, nos últimos dez anos, confirmados por biópsia cirúrgica ou percutânea. Os principais diagnósticos encontrados foram neoplasias, abscessos e hematomas. Os achados tomográficos baseiam-se na extensão do acometimento iliopsoas, no grau de atenuação, margens da lesão, presença de gás e/ou calcificações, destruição óssea, infiltração da gordura e acometimento de estruturas abdominais adjacentes. A TC é o método de escolha na avaliação do compartimento iliopsoas, podendo ser utilizada para orientar biópsias percutâneas, cirúrgicas ou drenagem. Porém, os achados isolados do estudo por TC, sem o conhecimento da história clínica, não são específicos para permitir a diferenciação das diversas patologias que acometem o compartimento iliopsoas.

2010-01-01

Chronic diseases of the lung parenchyma (CDoLP) in children encompass a vast number of distinct clinico-pathological conditions. The prevalence of CDoLP has continued to increase in the last 10-15 years and the paediatric radiologist will therefore have to become more familiar with the imaging appearances of CDoLP. This review highlights some of the key imaging appearances of CDoLP, focussing mainly on airways disease. We also explore issues around technique optimisation and dose minimisation that remain of paramount importance in children. (orig.)

Oxiuríase e migrações pré-históricas Oxyuriasis and prehistoric migrations

Directory of Open Access Journals (Sweden)

Adauto Araújo

Full Text Available O encontro de parasitos em material arqueológico tem permitido o acompanhamento da dispersão de agentes infecciosos e seus hospedeiros humanos no passado. Através desses achados, pôde-se retomar teorias propostas no início do século sobre contatos transpacíficos de populações asiáticas com a América do Sul. Assim foi feito, por exemplo, no caso do encontro de ovos de ancilostomídeos em material arqueológico datado de até sete mil anos antes do presente. O aumento da produção científica na área torna necessária, agora, a realização de trabalhos de síntese que avaliem o estado da arte e proponham modelos paleoepidemiológicos compreensíveis para a dispersão pré-histórica das parasitoses humanas. Nesse sentido, foi feito o presente trabalho, a partir dos recentes achados de ovos de Enterobius vermicularis em material arqueológico nas Américas. Diferentemente da infecção por ancilostomídeos, a oxiuríase não necessita de passagem pelo solo para a transmissão de um hospedeiro a outro, logo, sua persistência em uma dada população humana independe das condições climáticas. Poderia, portanto, ter sido trazida do velho para o novo continente, inclusive pelas migrações humanas que atravessaram o estreito de Bering. Tal fato pode explicar a maior dispersão geográfica dos achados e sua disseminação na América do Norte, desde dez mil anos até os tempos atuais. Na América do Sul, por outro lado, os achados arqueológicos só confirmaram sua existência ao longo da região andina, com achados no Chile e no Norte da Argentina. No Brasil, apesar do grande número de amostras examinadas, não foram encontrados ovos de Enterobius vermicularis em coprólitos. No presente trabalho, discutem-se modelos explicativos para a distribuição conhecida dessa parasitose em populações pré-históricas.Parasite findings in archeological material have made it possible to trace the dispersion of infectious agents and their human

Background Hereditary cancers account for 5–10% of cancers. In this study BRCA1, BRCA2 and CHEK2*(1100delC) were analyzed for mutations in 91 HBOC/HBC/HOC families and early onset breast and early onset ovarian cancer cases. Methods PCR-DHPLC was used for mutation screening followed by DNA sequencing for identification and confirmation of mutations. Kaplan-Meier survival probabilities were computed for five-year survival data on Breast and Ovarian cancer cases separately, and differences were tested using the Log-rank test. Results Fifteen (16%) pathogenic mutations (12 in BRCA1 and 3 in BRCA2), of which six were novel BRCA1 mutations were identified. None of the cases showed CHEK2*1100delC mutation. Many reported polymorphisms in the exonic and intronic regions of BRCA1 and BRCA2 were also seen. The mutation status and the polymorphisms were analyzed for association with the clinico-pathological features like age, stage, grade, histology, disease status, survival (overall and disease free) and with prognostic molecular markers (ER, PR, c-erbB2 and p53). Conclusion The stage of the disease at diagnosis was the only statistically significant (p < 0.0035) prognostic parameter. The mutation frequency and the polymorphisms were similar to reports on other ethnic populations. The lack of association between the clinico-pathological variables, mutation status and the disease status is likely to be due to the small numbers. PMID:19656415
