Perfil clínico-epidemiológico dos casos de tétano acidental ocorridos em Ribeirão Preto, Estado de São Paulo, no período de 1990 a 2009

Abstract

Introduction: Tetanus remains a major health problem in developing countries. In Brazil, despite technological advances, no significant decrease in the lethality rate of tetanus have been documented in recent years. Clinical and epidemiological data from patients who were treated in Ribeirão Preto in the state of São Paulo, Brazil in the last two decades were analyzed in this case series. Methods: Retrospective data regarding the demographics, clinical presentations and prognoses of patients admitted with clinical suspicion of tetanus to a tertiary referral university hospital from 1990 to 2009 were identified. The tetanus diagnosis was defined according to the Brazilian Ministry of Health criteria. Results: Eleven cases out of 23 patients with suspected tetanus were included in this study (47.8% of positive cases). The Tetanus Severity Score ranged from 0 to 8 points. There were no deaths, but two (18.2%) patients had permanent neurological deficits. The median length of hospital stay was 17 days (6-98 days). The absence of deaths can be explained by early clinical diagnosis and prompt treatment. Conclusions: Ribeirão Preto is an area in which tetanus is not a severe public health problem.
