Gestação heterotópica espontânea: relato de caso com diagnóstico e manejo oportunos / Spontaneous heterotopic pregnancy: a case report with appropriate diagnosis and management

Introdução: A gravidez heterotópica é um fenômeno obstétrico muito raro em concepções espontâneas no qual gestações tópica e ectópica coexistem. O diagnóstico é difícil, mas, se realizado precocemente, o prognóstico é favorável. Descrição do caso: Paciente do sexo feminino, de 35 anos de idade, admitida com quadro de dor abdominal e pequeno sangramento vaginal. Diagnosticada precocemente e tratada cirurgicamente por gravidez heterotópica naturalmente concebida. Como resultado, a gravidez tópica seguiu sem intercorrências. Conclusão: Esse caso enfatiza a necessidade de considerar esse diagnóstico diferencial e analisar clínica e ecograficamente as características globais da pelve, mesmo na ausência de fatores de risco em gestações tópicas.(AU)

Introduction: Heterotopic pregnancy (HP) is a rare obstetric phenomenon in spontaneous conceptions in which intrauterine and ectopic pregnancies coexist. The diagnosis is difficult, but, if performed early, the prognosis is favorable. Case description: A 35-year-old woman was admitted with abdominal pain and light vaginal bleeding. She was early diagnosed and surgically treated for a naturally conceived heterotopic pregnancy. As a result, the intrauterine pregnancy went on healthily. Conclusion: This case emphasizes the need to regard HP as a differential diagnosis and analyze the global pelvis characteristics both clinically and in ultrasound scans, even in the absence of risk factors when dealing with intrauterine pregnancies.(AU)

Omeprazole and adenocarcinoma in the stomach of rats submitted to duodenogastric reflux. Is there a protective effect?

PURPOSE: To investigate the role of omeprazole and nitrites on the gastric mucosa of rats submitted to specific techniques to induce duodenogastric reflux. METHODS: One hundred and twenty Wistar rats were divided into three groups: Group I (n=40) -gastrotomy; Group II (n=40) - duodenogastric reflux after gastrojejunoanastomosis latero-lateral (DGR); Group III (n=40) - retrograde duodenogastric reflux through the pylorus (DGR-P). The groups were divided into 4 subgroups of 10 animals, respectively treated for 16 weeks with water, omeprazole 1.6 mg / rat / day, nitrite 600 mg / kg / day and omeprazole plus nitrite simultaneously. RESULTS: The proliferative lesions found were: squamous hyperplasia - 69.1%, adenomatous hyperplasia in the anastomosis - 29.1% and prepyloric adenomatous hyperplasia - 42.5%. Adenocarcinomas were registered in 7 animals (5.8%): one in Group I (omeprazole plus nitrite), two in Group II (omeprazole and nitrite plus omeprazole) and four in Group III (water, nitrite, omeprazole and omeprazole plus nitrite). CONCLUSIONS: The occurrence of squamous hyperplasia, adenomatous hyperplasia and adenocarcinoma increased after gastrojejunal anastomoses, which cause duodenogastric reflux. The association of omeprazole did not protect the development of proliferative lesions and cancer induced by duodenogastric reflux in rats.
