Durante la pandemia del pH1N1 se atendieron casos severos de neumonías por diferentes etiologías, por lo que nosotros quisimos describir y comparar las características clínicas y laboratoriales de los casos de neumonías positivas y negativas al pH1N1.Estudio trasversal analítico, se revisaron las historias clínicas de los niños hospitalizados por neumonía entre los meses de junio a octubre del 2009 en el Instituto Nacional de Salud del Niño con exámenes virológicos de tr-PCR TR para pH1N1 e infiltrado pulmonares en sus radiografías.Estudiamos a 187 casos de neumonía, de los cuales 50 fueron neumonía adquirida en la comunidad (NAC) positivas al pH1N1 y 24 fueron como neumonía nosocomial (NN) positivas al pH1N1, de ellos fallecieron 12; todos presentaron factores preexistentes. Los casos de NAC positivos al pH1N1 tuvieron más presencia de fiebre (p<0,005) y linfopen...
