[Analysis of congenital malformations in newborns]. / Analiza wad wrodzonych u noworodków.

We analyzed data from 194 newborns with congenital malformations of central nervous, cardiovascular, gastro-intestinal, skeletal, genito-urinary systems and Down's syndrome. We detected that the highest frequency of congenital malformations occurred from may 1986 to december 1986. Congenital malformations were detected more frequently in female newborns and newborns delivered by multipara. The percentage of CNS malformations was constant but at the same time the number of other malformations were significantly changed. We made an attempt of statistical analysis of frequency and type of malformations taking into consideration possible influence of radiation during analyzed period.
