Prevalence of helicobacter pylori infection in advanced gastric carcinoma

There is substantial evidence that infection with Helicobacter pylori plays a role in the development of gastric cancer and that it is rarely found in gastric biopsy of atrophic gastritis and gastric cancer. On advanced gastric tumors, the bacteria can be lost from the stomach. Aims - To analyze the hypothesis that the prevalence of H.pylori in operated advanced gastric carcinomas and adjacent non-tumor tissues is high, comparing intestinal and diffuse tumors according to Lauren’s classifi cation. Methods - A prospective controlled study enrolled 56 patients from “Hospital Universitário”, Federal University of Rio Grande do Norte, Natal, RN, Brazil, with advanced gastric cancer, treated from February 2000 to March 2003. Immediately after partial gastrectomy, the resected stomach was opened and several mucosal biopsy samples were taken from the gastric tumor and from the adjacent mucosa within 4 cm distance from the tumor margin. Tissue sections were stained with hematoxylin and eosin. Lauren‘s classifi cation for gastric cancer was used, to analyse the prevalence of H. pylori in intestinal or diffuse carcinomas assessed by the urease rapid test, IgG by ELISA and Giemsa staining. H. pylori infected patients were treated with omeprazole, clarithromycin and amoxicillin for 7 days. Follow-up endoscopy and serology were performed 6 months after treatment to determine successful eradication of H. pylori in non-tumor tissue. Thereafter, follow-up endoscopies were scheduled annually. Chi-square and MacNemar tests with 0.05 signifi cance were used. Results - Thirty-four tumors (60.7%) were intestinal-type and 22 (39.3%) diffuse type carcinomas. In adjacent non-tumor gastric mucosa, chronic gastritis were found in 53 cases (94.6%) and atrophic mucosa in 36 patients (64.3%). All the patients with atrophic mucosa were H. pylori positive. When examined by Giemsa and urease test, H. pylori positive rate in tumor tissue of intestinal type carcinomas was higher than that in diffuse carcinomas. In tumor tissues, 34 (60.7%) H. pylori-positive in gastric carcinomas were detected by Giemsa method. H. pylori was observed in 30 of 56 cases (53.5%) in tissues 4 cm adjacent to tumors. This difference was not signifi cant. Eradication of H. pylori in non-tumor tissue of gastric remnant led to a complete negativity on the 12th postoperative month. Conclusions - The data confi rmed the hypothesis of a high prevalence of H. pylori in tumor tissue of gastric advanced carcinomas and in adjacent non-tumor mucosa of operated stomachs. The presence of H. pylori was predominant in the intestinal-type carcinoma

O enfermeiro e a laqueação de varizes esofágicas

O conceito de enfermeiro endoscopista ainda é recente, estando ligado em grande parte ao desenvolvimento das técnicas de diagnóstico e terapêutica em Gastroenterologia. A sua diversificação e complexidade tem vindo a reforçar o contributo do enfermeiro nesta área. Nesse sentido é da maior importância que se acompanhe esta evolução através da actualização de conhecimentos teóricos e práticos que se traduzam num desempenho eficaz e de qualidade.

Prevalence of celiac disease among first degree relatives of Brazilian celiac patients

Background - Several studies have shown that celiac disease, an autoimmune disorder that occurs in genetically susceptible individuals, is highly prevalent among relatives of celiac patients. Aim - To determine the prevalence of celiac disease in a group of first degree relatives of Brazilian celiac patients. Methods - First degree relatives of celiac patients attending the Brasilia University Hospital Pediatric Gastroenterology Outpatient Clinic or the Celiac Disease Investigation Center, Brasília, DF, Brazil, between March 2001 and November 2004 were invited to undergo serological screening for celiac disease applying the IgA anti-endomysium antibody test (IgA-EMA). All positive IgA-EMA sera underwent a second screening using the IgA anti-tissue transglutaminase antibodies test. Duodenal or small intestinal biopsies were performed in all subjects positive to serological testing. Biopsy samples were classified as type (O) normal, (I) infiltrative, (II) infiltrative hyperplastic, (III) flat destructive, and (IV) atrophic hypoplastic. The final diagnosis was ascertained in subjects showing positive serological tests and a grade I to III small intestinal lesion. Results - Nine new cases of celiac disease were found among the 188 first degree relatives tested (4.8%). Conclusion - The present study confirms the high prevalence of celiac disease among first degree celiac patients’ relatives and reinforces the need of extensive diagnostic screening in this specific group.

Este relatório foi realizado no âmbito do estágio curricular no Hospital Veterinário do Baixo Vouga de 1 de Setembro de 2015 a 31 de Janeiro de 2016. A primeira componente trata da casuística acompanhada no estágio. A área médica mais comum foi a gastroenterologia. A segunda componente consiste na revisão bibliográfica da aspergilose canina complementada com um caso clínico acompanhado no estágio. A aspergilose sino-nasal canina ocorre principalmente em indivíduos jovens ou de meia-idade, mesaticéfalos ou dolicocéfalos e saudáveis. O seu diagnóstico implica o conjunto de vários exames, nomeadamente imagiológicos, cultura de fungos, histopatologia, serologia e diagnóstico molecular. O tratamento recomendado é o tópico. A aspergilose disseminada é menos frequente, sendo mais comum na raça Pastor Alemão. Sendo geralmente mais grave, o tratamento passa essencialmente pela terapia antifúngica sistémica. O uso de fungicidas tem sido muito associado à ocorrência de resistências cruzadas a antifúngicos azóis, dificultando o tratamento destas infeções; Abstract: Small Animal Medicine This report was elaborated following a traineeship at the Hospital Veterinário do Baixo Vouga from September 1st, 2015 to January, 31st, 2016. The first component covers the casuistry accompanied during the same. The most prevalent medical field was the gastroenterology. The second component consists of a literature review of canine aspergillosis along with the report of a case followed during the internship. Canine sinonasal aspergillosis primarily affects young to middle-aged, mesaticephalic or dolichocephalic and healthy dogs. Its diagnosis involves a conjunction of medical exams, namely imagiologic, fungal culture, histopathology, serology and molecular diagnosis. The recommended treatment is the topical one. Disseminated aspergillosis is more infrequent, occurring usually in German Shepard Dogs. Being more grievous, its treatment is based upon the administration of systemic antifungals. The use of azole fungicides has been linked to the development of cross-resistances between these and the antifungal azoles, making it difficult to treat such infections.
