OBJECTIVE: To evaluate clinical and evolutive characteristics of patients admitted in an intensive care unit after cardiopulmonary resuscitation, identifying prognostic survival factors.METHODS: A retrospective study of 136 patients admitted between 1995 and 1999 to an intensive care unit, evaluating clinical conditions, mechanisms and causes of cardiopulmonary arrest, and their relation to hospital mortality.RESULTS: A 76% mortality rate independent of age and sex was observed. Asystole was the most frequent mechanism of death, and seen in isolation pulmonary arrest was the least frequent. Cardiac failure, need for mechanical ventilation, cirrhosis and previous stroke were clinically significant (p<0.01) death factors.CONCLUSION: Prognostic factors supplement the doctor's decision as to whether or not a patient will benefit from cardiopulmonary resuscitation.

Os anéis de Kayser-Fleischer (K-F) são alterações pigmentadas localizadas na membrana de Descemet, principalmente na região perilímbica na córnea. Estão associadas à doença de Wilson, sendo a manifestação oftalmológica mais comum da mesma e se correlacionam diretamente ao tempo de evolução desta doença. Os anéis de K-F caracterizam-se pela deposição de granulações de cobre de tamanhos e formas variadas na córnea e predominam na periferia corneana. A doença diretamente ligada ao aparecimento dos anéis de K-F, a doença de Wilson, caracteriza-se por distúrbio metabólico com acúmulo de cobre nos tecidos humanos, principalmente no fígado. A presença de anéis pigmentados na córnea nem sempre é diagnóstico de anéis de K-F, devendo ser diferenciados de outras alterações pigmentadas da córnea não ligadas à doença de Wilson. Estas englobam a vasta maioria de doenças hepato-biliares que podem ocasionar acúmulo de cobre, além de corpos estranhos intra-oculares contendo cobre, mieloma múltiplo, entre outras. O objetivo do presente artigo é revisar alguns aspectos desta alteração pigmentada corneana, os anéis de K-F, além de descrever algumas características da principal doença ligada ao seu aparecimento.

Kayser-Fleischer (K-F) rings are characterized by copper deposition on Descemet's membrane, mainly near the limbus. They are strongly associated with Wilson's disease and are the most common ocular finding in this disease. There is an association between the presence of the rings and the time of disease. The K-F rings are composed of small copper granulations of different sizes on the cornea. Wilson's disease is characterized by an accumulation of copper in the body, primarily in the liver. The occurrence of pigmented rings on the cornea not associated with Wilson's disease have been reported and must be differentiated from the K-F rings. They occur most often in hepatobiliary diseases, multiple myeloma and ocular copper containing foreign bodies. The purpose of this paper is to review the K-F rings and Wilson's disease.

Objetivos — Determinar a prevalência de infecção pelo Helicobacter pylori em pacientes de 2 a 18 anos submetidos a biopsias gástricas por endoscopia esôfago-gástrica-duodenal no Hospital de Clínicas de Porto Alegre, RS, durante o período de 1990 a 1997, correlacionando-a com os achados clínicos, endoscópicos e anatomopatológicos. Métodos - Estudo transversal embasado na revisão de arquivos médicos e de laudos anatomopatológicos, sendo estes últimos revistos por médico patologista que desconhecia as informações clínicas e laudos anatomopatológicos prévios. Resultados - Foram avaliados 181 pacientes e obteve-se uma prevalência de infecção pelo Helicobacter pylori de 24,86% (45 casos). Na histologia, gastrite foi encontrada em 38 pacientes dos 45 com Helicobacter pylori positivo e em 45 do 136 Helicobacter pylori negativo. Úlcera péptica foi encontrada em 6 dos 45 Helicobacter pylori positivo e em 3 dos 136 Helicobacter pylori negativo. Conclusão - O estudo demonstrou relação significativa da infecção do Helicobacter pylori com alterações principalmente histológicas nas crianças avaliadas.

Objectives — To determinate prevalence of Helicobacter pylori infection in a group of symptomatic patients between 2 and 18 years old who were submitted to gastric biopsy during upper endoscopy done in the period of 1990-97. To correlate the histological findings with clinical and endoscopical data. Methods — A cross-sectional study done after review of clinical and histopathological data. Histopathological sections were reviewed by a pathologist, who did not know the clinical information and the previous histopathological reports. Results — Among 181 patients evaluated, prevalence of Helicobacter pylori infection was 24.86% (45 positive cases). In pathological analysis, gastritis was found in 38/45 of the positive Helicobacter pylori patients and in 45/136 negative Helicobacter pylori. Gastric ulceration was found in 6/45 positive Helicobacter pylori and in 3/136 negative Helicobacter pylori. Conclusion — This study stated a significative association between Helicobacter pylori infection and pathological abnormalities in children evaluated in the "Hospital de Clínicas de Porto Alegre", RS, Brazil.
