Common congenital anomalies.

Congenital anomalies account for a substantial proportion of childhood morbidity and mortality. They have become proportionately larger because of the decline of such other categories as infections or birth trauma. Approximately 3% of newborns have a serious handicapping or potentially lethal condition; in longterm studies the frequency is much higher. There is no good evidence to suggest that the rates of congenital anomalies are increasing, although this is a common perception. This article discusses diagnosis and management (especially genetic implications) of heart defects, neural tube defects, orofacial clefting, dislocated hip, clubfoot, and hypospadias.
