“…Verificaram-se reinternação da criança pelo mesmo episódio em 2,1% dos casos e reinternação da mesma criança por outro episódio em 24,8% A idade mostrou-se inversamente relacionada à prevalência de sibilância nas crianças Guarani. A precocidade na apresentação de sibilân-cia em crianças foi descrita por diversos autores em populações carentes atendidas em serviços públicos de saúde em cidades do Sul e Sudeste do Brasil 2,20,21 . Em estudo em pacientes atendidos em unidades básicas de saúde em São Paulo, encontrou-se uma prevalência elevada de sibilância, com quase metade dos lactentes apresentando pelo menos um episódio de sibilância já no primeiro ano de vida 2 .…”
