Epilepsia e crises epilépticas são transtornos cerebrais comuns em idosos e estão associadas com uma taxa de mortalidade elevada que pode ser atribuída à etiologia ou a causas relacionadas à epilepsia.Objetivo Descrever preditores de mortalidade em pacientes idosos internados com epilepsia e crise epiléptica.Método Estudo retrospectivo, envolvendo idosos hospitalizados, de 60 anos ou mais, que foram admitidos de janeiro de 2009 a dezembro de 2010 por terem apresentado epilepsia e crises epilépticas durante a hospitalização. Cento e vinte pacientes foram incluídos no estudo.Resultados A etiologia mais comum foi o acidente vascular cerebral isquêmico (37%), seguido por neoplasias (13%), acidente vascular cerebral hemorrágico (12%), demências (11,4%) e distúrbios metabólicos (5,5%). Na análise univariada, duração da doença (p = 0,04), estado de mal epiléptico (p < 0,001) e etiologia metabólica (p = 0,005) estiveram associados com mortalidade. Entretanto, após ajuste por regressão logística, apenas estado de mal epiléptico permaneceu como preditor independente de morte (odds ratio = 13; IC95% = 2,3 a 72; p = 0,004).Conclusão Neste estudo, estado de mal epiléptico foi um fator independente de risco para morte durante hospitalização.

Epilepsy and epileptic seizures are common brain disorders in the elderly and are associated with increased mortality that may be ascribed to the underlying disease or epilepsy-related causes.Objective To describe mortality predictors of epilepsy and epileptic seizures in elderly inpatients.Method Retrospective analysis was performed on hospitalized elderly who had epilepsy or epileptic seizures, from January 2009 to December 2010. One hundred and twenty patients were enrolled.Results The most common etiology was ischemic stroke (37%), followed by neoplasias (13%), hemorrhagic stroke (12%), dementias (11.4%) and metabolic disturbances (5.5%). In a univariate analysis, disease duration (p = 0.04), status epilepticus (p < 0.001) and metabolic etiology (p = 0.005) were associated with mortality. However after adjustment by logistic regression, only status epilepticus remained an independent predictor of death (odds ratio = 13; 95%CI = 2.3 to 72; p = 0.004).Conclusion In this study status epilepticus was an independent risk factor for death during hospitalization.

Transmission of Mycobacterium bovis from cattle to humans has been reported and can cause tuberculosis (Tb) and a problem in certain risk populations. Therefore, knowledge of resistance of M. bovis towards antibiotics used for therapy of human Tb could help avoiding cure delay and treatment cost increase when dealing with drug resistant organisms. We therefore evaluated the susceptibility of M. bovis isolates towards streptomycin, isoniazide, rifampicin, ethambutol, and ethionamide, the first line antibiotics for human Tb. Therefore, 185 clinical samples from cattle with clinical signs of tuberculosis were processed and submitted to culturing and bacterial isolates to identification and drug susceptibility testing using the proportion method. Among 89 mycobacterial strains, 65 were identified as M. bovis and none were resistant to any of the antibiotics used. Confirmation of present results by future studies, enrolling a large number of isolates and designed to properly represent Brazilian regions, may favor the idea of using isoniazide preventive therapy as part of a Tb control strategy in special situations. Also, nucleic acids from bacterial isolates were submitted to rifoligotyping, a recently described reverse hybridization assay for detection of mutations causing resistance towards rifampicin. Concordance between the conventional and the molecular test was 100%, demonstrating the use of such methodology for rapid evaluation of drug susceptibility in M. bovis.
