[Congenital anomalies in the material of City Hospital in Bydgoszcz during the period of 1995-1999].

OBJECTIVE
The analysis occurrence of developmental defects of newborns in the City Hospital in Bydgoszcz during the period 1995-1999.


MATERIALS AND METHODS
Over the period of 5 years, 14,943 newborns delivered in City Hospital in Bydgoszcz. The group of 358 (2.40%) with developmental anomalies was analysed retrospectively. The subject of the study was to estimate the types of malformations and their frequency.


RESULTS
In our material cardiovascular anomalies (29.05%), reproductive system anomalies (20.11%) and muscosceletal anomalies (18.72%) were most frequent. Breech-presented or transverse lie fetuses had double the risk of any anomalies. In addition, pre-term delivery were not positively associated with any newborn defects. The frequency of occurrence cesarean sections was positively correlated with presence of congenital malformations.
