作者指出,近来成年人患脊髓灰白质炎比过去增多,由于现在小儿已经广泛地进行了预防,将来这种趋势还会增加。从1957到1961年间,有42例拟诊为“原发性神经炎”的病人在意大利佛罗棱薩地方收入医院。患者中男性27人,女性15人。在年龄上没有小于11岁的,11到15岁的7人,16到20岁的12人,其余23人(包括所有死亡的14人)都在21岁以上。 The authors note that recent adult-onset glaucomatous inflammation has increased over the past and this trend is likely to increase in the future as widespread prevention has now occurred in children. From 1957 to 1961, 42 patients who were diagnosed with “primary neuritis” were admitted to hospitals in the Florens region of Italy. There were 27 males and 15 females. There are no less than 11-year-olds, 11 to 15-year-olds 7, 12 to 16-year-olds 12, and the remaining 23 (including all 14 who died) are over the age of 21.
