RESUMO Pacientes com demência são comumente admitidos em setores de internação. O objetivo deste estudo foi descrever a frequência de demência em pacientes idosos internados em uma enfermaria de geriatria de um hospital universitário terciário brasileiro e identificar associações entre demência e fatores clínicos e sociodemográficos. Métodos: Todos os pacientes internados na enfermaria de geriatria de um hospital universitário público brasileiro no período de 1 de março de 2014 a 31 de janeiro de 2015 foram avaliados por geriatras. Os pacientes foram divididos em dois grupos: com ou sem diagnóstico prévio de demência. Análise univariada foi utilizada na comparação dos resultados dos dois grupos por meio do Teste do Qui-Quadrado, teste t-Student e o teste de Mann-Whitnney. Resultados: Foram avaliados 103 pacientes idosos, com idade média de 82 (±7,9) anos; 74,7% apresentaram escolaridade baixa (<4 anos), 66% usavam polifarmácia, 57,2% desenvolveram delirium durante a hospitalização e 59% eram totalmente dependentes das atividades básicas da vida diária. O diagnóstico de demência foi observado em 59 indivíduos (57%). Conclusão: A frequência de demência foi alta entre pacientes idosos avaliados. A associação entre demência e certas condições clínicas, como a incontinência, o delírio e o uso de drogas psicoativas, está em consonância com a literatura médica.

ABSTRACT Patients with dementia are commonly admitted to inpatient sectors. The aim of this study was to describe the frequency of dementia among elderly inpatients admitted to the Geriatrics Sector of a Brazilian Tertiary University Hospital, and to identify associations between dementia and clinical and sociodemographic factors. Methods: All patients admitted to the Geriatrics Sector of a public Brazilian university-hospital from March 1st 2014 to January 31st 2015 were assessed by geriatricians. The patients were divided into groups "with or without diagnosis of dementia". Univariate analysis was performed between these two groups using the Chi-Square Test, Student's t-test or the Mann-Whitney Test. Results: One hundred and three elderly inpatients, with a mean age of 82 (±7.9) years, were assessed. Overall, 74.7% had low educational level (<4 years), 66% used polypharmacy, 57.2% developed delirium during hospitalization and 59% were totally dependent for basic activities of daily living. The diagnosis of dementia was observed in 59 (57%) subjects. Conclusion: The frequency of dementia was high among the elderly inpatients evaluated. The association between dementia and certain clinical conditions, such as incontinence, delirium and use of psychoactive drugs, was in line with the medical literature.

PURPOSE: To evaluate the efficacy of surgical treatment for esophageal perforation. METHODS: A systematic review of the literature was performed. We conducted a search strategy in the main electronic databases such as PubMed, Embase and Lilacs to identify all case series. RESULTS: Thirty three case series met the inclusion criteria with a total of 1417 participants. The predominant etiology was iatrogenic (54.2%) followed by spontaneous cause (20.4%) and in 66.1% the localization was thoracic. In 65.4% and 33.4% surgical and conservative therapy, respectively, was considered the first choice. There was a statistically significance different with regards mortality rate favoring the surgical group (16.3%) versus conservative treatment (21.2%) (p<0.05). CONCLUSION: Surgical treatment was more effective and safe than conservative treatment concerning mortality rates, although the possibility of bias due to clinical and methodological heterogeneity among the included studies and the level of evidence that cannot be ruled out.
