1997年の奈良県における小児急性神経疾患の発生状況

Abstract

A regional survey of the incidence of several acute infantile neurological disorders in 1997 was performed in Nara, concerning the incidence of aftereffects in preventive vaccinations. The most frequent disorder in the survey was 'aseptic meningitis' with 238 cases out of the total of 394, while 'epilepsy' was the second with 98 cases. Four out of eight patients with 'encephalitis' were of complication of rubella infection. Six cases of 'encephalopathy', including Reye syndrome, were reported in approximately 230,000 children in Nara in 1997 (0.0017%), while one case of Reye syndrome after DPT vaccination occurred (0.0014%) among 70,000 children who were injected with DPT in Nara in 1997.
