胎儿风疹感染常造成先天性聋。近年来发现可以用自动免疫的手段来预防。为此要了解这种先天性聋的发病率。本文作者们对丹麦先天性聋的儿童进行了风疹抗体的血清学测定,并与相同年龄无听觉损伤的对照组进行了比较。共对137例儿童做血清试验,分为三组:(1)7例婴儿。年龄小于6个月,取血平均年龄为2个月;(2)58例儿童平均年龄29个月,这二组儿童全部有先天性聋,均经不同听力学手段测得可靠的生理听觉阈值。(3)对照组72例平均年龄29个月的没有
Fetal rubella infections often cause congenital deafness. In recent years, it can be prevented by means of autoimmunity. To understand this incidence of congenital deafness. The authors of this study performed a serological test for Rubella antibodies in children with congenital deafness in Denmark and compared them to controls of the same age without auditory impairment. A total of 137 cases of children do serum tests, divided into three groups: (1) 7 cases of infants. (2) The mean age of 58 children was 29 months. All of the two groups had congenital deafness, and the reliable physiological hearing thresholds were measured by different audiological methods . (3) 72 cases in the control group with an average age of 29 months did not
