[Epidemiology of congenital malformations in neonates born alive in the Institute of Gynecology and Obstetrics of Medical University in Lodz in the years 2001-2003].
Institute of Gynaecology and Obstetrics of Medical University in Lodz acceded the Polish Register of Congenital Malformations and keeps on propagating the program. The aim of the study was to estimate the frequency of congenital malformations in newborns delivered in the Institute of Gyneacology and Obstetrics in Lodz in the years 2001-2003 and to analyse some epidemiological parameters concerning inborn defects in the region of Lodz. The study is based on the retrospective analysis. All neonates born alive in our Institute in the years 2001-2003 were taking into consideration. The data about inborn malformations was collected from the medical documentation and the results were confronted with demographic analysis of the region of Lodz.


RESULTS
Among 66474 neonates born alive during analysed period of time in the region of Lodz, 4507 (6,78%) were delivered in the Institute of Gyneacology and Obstetrics in Lodz. There were 106 newborns congenitally malformed, so the percentage of inborn defects reached 2,35% of all neonatal population. From the region of Lodz 966 babies with inborn malformations were notified to the Polish Register of Congenital Malformations, and 106 (10,9%) malformed newborns were registered from our Institute. Malformations of heart and circulatory system were the most frequent--28,8%, defects of skeletal and muscular system were the next -18%, and malformations of urogenital system formed 16,2%. In the region of Lodz there were 477 neonatal deaths and 121 cases were caused by congenital anomalies, which makes the percentage of 25,4% of neonatal mortality.


CONCLUSIONS
1. Congenital malformations are the one of the main reasons of neonatal and infantile mortality. 2. The program of registrating malformations helps in exact epidemiological analysis of congenital anomalies in newborns.
