LINFOMA DE BURKITT EM ESTÔMAGO: RELATO DE CASO / BURKITT'S LYMPHOMA OF STOMACH: CASE REPORT

Introdução: Linfoma não-hodgkin em trato gastrointestinal é frequente, entretanto linfoma de burkitt primário em estômago é apresentação rara. Objetivo: Relatar o caso de um paciente com queixa de massa abdominal. Resultados: Foi realizado ultrassonografia e tomografia computadorizada de abdômen sendo visualizado tumoração epigástrica. Durante a cirurgia via laporotomia mediana foi visualizado foi visualizado tumor de antro gástrico aderido ao cólon transverso. A análise histopatológica comprovou linfoma não-hodgkin do tipo Burkitt. Paciente após cirurgia foi encaminhado para centro onco-hematológico especializado. Conclusão: O caso relatado reflete rara manifestação do linfoma de Burkitt em paciente com idade pouco frequente e enfoca a importância clínica e a necessidade do diagnóstico precoce, como fundamental na redução da morbimortalidade pelo reconhecimento clínico.Palavras-chave: Linfoma não Hodgkin.

Objective: The aim of this study was to report the case of an individual complaining of abdominal mass. Results: abdominal ultrasonography and computed tomography were performed and it was found epigastric tumor. During the surgery through median laparotomy, we visualized gastric antrum tumor that was adhered to the transverse colon. Histopathological analysis confirmed non-Hodgkin Burkitt's lymphoma. After the surgery, the patient was sent to a specialized center of oncology/hematology. Conclusion: This case reflects a rare manifestation of Burkitt's lymphoma in the stomach of a patient with uncommon age. The report focuses on the clinical importance and the need of early diagnosis in order to reduce morbidity and mortality by clinical recognition.Keywords: Non-Hodgkin lymphoma. Burkitt's lymphoma.

Children and adolescents ostomized in a reference hospital. Epidemiological profile

Abstract Objectives To assess the epidemiological profile of children and adolescents with intestinal stoma, assisted at the Presidente Dutra University Hospital (HUPD), São Luís (MA). Methods Observational, descriptive, retrospective, and individuated study. Data were collected from 110 children and adolescents with elimination intestinal stoma, from January 2006 to February 2013. The following variables were analyzed: age, gender, patient origin, and stomata indication, type, and temporal character. After data collection, descriptive analysis was made by Bioestat 5.0 program. Results Of 110 patients, 78.2% were male and 21.8% female. The average age was 9.4 years old. 55.5% came from the Maranhão state countryside, and 44.5% from the capital, São Luís. Regarding stoma type, colostomies made up 88.2%, and were 11.8% ileostomies, all temporary stoma. The main cause was trauma (42.7%), with firearm abdominal puncture being the most frequent cause (71.5% of the category); followed by congenital anomalies (38.2%), and obstructive (5.4%) and inflammatory (4.5%) causes. Conclusion Studied children and adolescents were mostly male, from Maranhão state countryside. The main cause was trauma, and colostomy was the most common stoma type

Use of 2-octyl cyanoacrylate adhesive in rat liver induced lesion Uso adesivo de 2-octil cianoacrilato em lesão induzida de fígado de ratos

PURPOSE: To evaluate the healing process of rat traumatic liver lesion corrected with the use of 2-octyl cyanoacrylate adhesive, compared to the use of biologically absorbable chromed catgut thread suture. METHODS: Thirty mail adult rats were divided into two groups (15 per group) according to the used method for liver lesion correction as follows: adhesive group (AG), and catgut group (CG); each group being divided into three subsets of five animals (7th, 14th, and 21st day), respectively, according to post-surgery evaluation. All animals were submitted to homogeneous lesion applying synthetic bonding to AG and using chromed catgut suture to CG for lesion correction. Macroscopic and microscopic parameters of healing processes were evaluated. RESULTS: Both groups of animals showed excellent abdominal wall healing, with no evidence of infection, and no abdominal cavity peritonitis or abscess. The presence of adherence was observed in both groups with no statistically significant difference. As to macroscopic evaluation, there was statistically significant difference with respect to specific factors of clinical inflammation (ischemic inflammation and giant celular inflammatory reaction) between animals evaluated on the 10th day (ischemic necrosis and giant celular inflammatory reaction) among animals evaluated on the 14th day (A14 versus C14). CONCLUSION: Applying 2-octyl-cyanoacrylate adhesive for correcting rat liver lesion does not change healing process when compared to the use of chromed catgut stitch.<br>OBJETIVO: Avaliar o processo de cicatrização de lesão induzida em fígado de rato utilizando adesivo de 2-octil cianoacrilato em comparação com a sutura com catgut cromado. MÉTODOS: Utilizou-se 30 ratos adultos, machos, distribuídos em dois grupos de 15 animais denominados de grupo adesivo (GA) e grupo catgut (GC); cada grupo foi dividido em três subgrupos, cada um com cinco animais, de acordo com a data marcada para avaliação pós-operatória (sétimo, décimo quarto e vigésimo primeiro dia). Todos os animais foram submetidos à lesão homogênea, aplicando o adesivo sintético no GA e utilizando sutura com catgut cromado no GC para correção das lesões. Foram avaliados parâmetros de macroscópicos e microscópicos do processo de cicatrização. RESULTADOS: Em ambos os grupos os animais evoluíram com boa cicatrização da parede abdominal, sem evidência clínica de infecção, sem abscessos ou peritonite na cavidade abdominal; a presença de aderências foi observada em ambos os grupos sem diferenças estatisticamente significantes; quanto à avaliação microscópica só houve diferença estatisticamente significante quanto aos parâmetros específicos de inflamação crônica (necrose isquêmica e reação gigantocelular) entre os animais avaliados no décimo quarto dia (A14 vs. C14). CONCLUSÃO: O emprego de adesivo de 2-octil cianoacrilato na correção de lesão em fígado de rato não altera o processo de cicatrização quando comparado ao uso de sutura com fio de categute cromado
