随着计划生育工作的开展,优生优育工作正在大力推行,笔者根据临床的实践认为:小儿遗传病中以智力低下、先天性心脏病、指趾畸形、唇腭裂、先天性聋哑等发病率较高,这对优生优育是极不利的,为此就我们发现的这些疾病的病例与其病因作一些初步探讨。(一)智力低下这是多种因素引起的,其中患遗传性疾病者(染色体和基因缺陷)占居重要地位。智力是一个复杂的问题,涉及到医学、社会、教育、经济等各方面。美国调查智力低下占1.25%、北京调查占3.4‰、内蒙古呼市调查约14万人中为2.4‰。由于智力商数的分类国内外无统一数据,国
With the development of family planning work, prenatal and postnatal care work is vigorously promoted, the author based on clinical practice that: children with genetic diseases in mental retardation, congenital heart disease, toe deformities, cleft lip and palate, congenital deaf and other more than the incidence High, which is extremely unfavorable for prenatal and postnatal care, for which we found some cases of these diseases and their causes for some preliminary discussion. (A) mental retardation This is caused by many factors, including those with genetic diseases (chromosomes and genetic defects) occupy an important position. Intelligence is a complex issue involving medical, social, educational, economic and other aspects. The United States accounted for 1.25% of mental retardation, Beijing survey accounted for 3.4 ‰, Inner Mongolia Hohhot survey of about 140,000 people was 2.4 ‰. Due to the classification of intelligence quotient without uniform data at home and abroad, the country
