Spectrum of congenital surgical malformations in newborns.

A prospective study to detect the frequency and distribution of congenital surgical malformations in a rural hospital setting in Maharashtra was carried out. A total of 3000 consecutive births over a 9-month period was included and the frequency of congenital malformations was 21.1 per 1000 births. Stillbirths were associated with a higher incidence of malformations (14.5%) as compared to live births (1.8%). The commonest systems affected were the gastro-intestinal tract and the genito-urinary tract (20.4% each) followed by the central nervous system (17.3%). Among the various possible risk factors studied, a higher incidence of congenital malformations was associated with increasing maternal age (> 35 years), higher gravida mothers (> G4), parental consanguineous marriages, previous history of abortions, maternal hypertension, etc.
