Abstract
The practical approach to effective prevention and diagnosis of congenital anomalies involving them early (prenatal or neonatal), correctly and completely. Both actions require but etiopathogenic knowledge, clinical skills and appropriate means of exploration. Epidemiological studies can contribute in a meaningful way to identify and assess risk factors involved in the etiopathogenesis of congenital anomalies. This research is part of a large study (retrospective and prospective), which aims to identify factors involved in congenital anomalies determinism towards a diagnostic algorithm for an early and optimal case management.
