Low prevalence of H. pylori Infection in HIV-Positive Patients in the Northeast of Brazil
<p>Abstract</p> <p>Background</p> <p>This study conducted in Northeastern Brazil, evaluated the prevalence of <it>H. pylori </it>infection and the presence of gastritis in HIV-infected patients.</p> <p>Methods</p> <p>There were included 113 HIV-positive and 141 age-matched HIV-negative patients, who underwent upper gastrointestinal endoscopy for dyspeptic symptoms. <it>H. pylori </it>status was evaluated by urease test and histology.</p> <p>Results</p> <p>The prevalence of <it>H. pylori </it>infection was significantly lower (p < 0.001) in HIV-infected (37.2%) than in uninfected (75.2%) patients. There were no significant differences between <it>H. pylori </it>status and gender, age, HIV viral load, antiretroviral therapy and the use of antibiotics. A lower prevalence of <it>H. pylori </it>was observed among patients with T CD4 cell count below 200/mm<sup>3</sup>; however, it was not significant. Chronic active antral gastritis was observed in 87.6% of the HIV-infected patients and in 780.4% of the control group (p = 0.11). <it>H. pylori </it>infection was significantly associated with chronic active gastritis in the antrum in both groups, but it was not associated with corpus chronic active gastritis in the HIV-infected patients.</p> <p>Conclusion</p> <p>We demonstrated that the prevalence of <it>H. pylori </it>was significantly lower in HIV-positive patients compared with HIV-negative ones. However, corpus gastritis was frequently observed in the HIV-positive patients, pointing to different mechanisms than <it>H. pylori </it>infection in the genesis of the lesion.</p

Incidência de cefaléia em uma comunidade hospitalar Headache incidence in a hospital community
O objetivo foi determinar em um grupo de pessoas de uma comunidade hospitalar a incidĂŞncia de cefalĂ©ia e para esta a frequĂŞncia, principais caracterĂsticas e investigações mĂ©dicas mais solicitadas. Utilizamos a combinação de questionário e entrevista. Do total de 1006 fichas aleatoriamente preenchidas, 987 pessoas responderam corretamente aos quesitos e destas 380 (38,5%) eram portadoras de cefalĂ©ia. Baseados na Classificação Internacional de CefalĂ©ia dividimos os portadores em dois principais grupos, a migrânea e a cefalĂ©ia do tipo tensional. As demais foram agrupadas num terceiro grupo. A idade mĂ©dia foi 31,18 anos, com predomĂnio do sexo feminino em todos os tipos de cefalĂ©ia. A presença de histĂłria familiar foi positiva em 76,8% dos entrevistados. As caracterĂsticas mais frequentes foram: localização frontal, tipo pulsátil e intensidade moderada. O principal fator desencadeante foi o estresse. A procura de acompanhamento mĂ©dico deu-se em 41,3% dos portadores. Destes, aproximadamente 56% consultaram um clĂnico geral, 23% consultaram um neurologista e 21% procuraram outras especialidades. O RX de crânio foi o exame mais solicitado pelos generalistas e o eletrencefalograma pelos neurologistas. A tomografia computadorizada do crânio nĂŁo foi solicitada com frequĂŞncia<br>The purpose was to describe the main features of headache incidence in a hospital community, its frequency and the most requested medical investigation. Due to the stressful work environment, hospital is considered to hold a high-risk population. Interviews and questionnaires were utilized. Of a 1006 files, which were randomly filled out, 987 could be analyzed. Of all, 38,5% were from headache sufferers. By using a table of pain symptoms taken from the International Headache Society classification as a pattern, headaches were assigned as migraine, tension-type and other. The mean age was 31.18 and the frequency in females was higher than in males, at any type. Family occurrence in first-degree relatives was 76.8%. Frontal location, medium intensity and pulsation were the most described features. Stress was the most frequently mentioned trigger factor. A physician was consulted only by 41.3%. Cranium X-ray was the most frequently requested exa
