Repeated Epley's maneuvers in less sessions rendered more positional nystagmus-free patients when compared to those submitted to more sessions of single maneuvers.

Colonization of hospitalized patients with methicillin-resistant Staphylococcus aureus (MRSA) is of increasing concern. To evaluate this problem in Intensive Care Units (ICUs) in Brazil, we studied 100 patients admitted to two ICUs from April to June, 1997. Of the 100 patients, 70 were male, 53 were age 60 years or older, 55 were previously hospitalized, 78 were transferred to the ICU from other hospital units, 49 had received antibiotic therapy, and 66 had undergone recent surgery. Nasal and axillary swab cultures were obtained on admission and every 48 hours thereafter until discharge. MRSA were identified by plating any cultured S. aureus on Mueller-Hinton agar containing 6 microg/ml of oxacillin. At the time of admission, 46 (46%) of the patients were colonized with MRSA. No associated risk factors for acquiring MRSA (age, previous hospitalization, prior surgery) could be identified. Of the 54 patients negative for MRSA on admission, 28 (52%) became colonized while in the ICU. Sixteen (22%) of the 74 colonized patients (colonized either on admission or during ICU stay) had associated respiratory or urinary tract infections due to MRSA, and 9 (56%) died. No correlation with special risk factors (invasive procedures, antibiotic use, age, chronic disease) was identified. MRSA occurred frequently, but there was minimal evidence of associated risk factors. Thus, control of MRSA cannot be accomplished by targeting special factors alone, but requires attention to preventing microbial spread in all areas. Of special concern is the high frequency of acquiring the organism in the ICU (52%). Education concerning the importance of hand washing, environmental surface cleaning, and barrier protection from infected patients is needed.

O OBJETIVO: o objetivo deste trabalho foi verificar a eficácia da reabilitação vestibular personalizada (RVP) em diferentes quadros otoneurológicos. FORMA DE ESTUDO: clínico retrospectivo. MATERIAL E MÉTODO: Foi realizado um estudo retrospectivo que constou de uma descrição do programa de reabilitação vestibular de 37 pacientes, com idade entre 21 a 87 anos, vinte e seis do sexo feminino, onze do sexo masculino, com quadros otoneurológicos variados, atendidos no Ambulatório de Otoneurologia do Departamento de Otorrinolaringologia da Irmandade da Santa Casa de Misericórdia de São Paulo, no período de 2002 a 2003. Estes foram submetidos à avaliação otoneurológica e depois de realizado o diagnóstico pelo otorrinolaringologista, encaminhados para a reabilitação vestibular, realizada semanalmente no ambulatório, e em casa diariamente. Cada paciente seguiu programas específicos de exercícios, considerando-se os achados ao exame vestibular, o quadro clínico e, principalmente, os sintomas apresentados. Os exercícios foram baseados em diferentes protocolos descritos na literatura. Foi realizada uma análise individual da evolução clínica e em conjunto, a fim de verificar a eficácia da RVP em diferentes quadros clínicos. CONCLUSÃO: Pudemos concluir que o programa de RVP mostrou-se um recurso terapêutico efetivo na diminuição e extinção dos sintomas e conseqüente melhora na qualidade de vida de pacientes portadores de diferentes quadros clínicos.
