[The occurrence of malformations in newborns from highly polluted environment: own materials from years 1993-1998].

OBJECTIVES: Epidemiological rates and the structure of malformations in live born infants from the II Chair and Clinic of Obstetrics and Gynecology in Zabrze in the year 1993-1998 are shown in this paper. MATERIAL AND METHODS: 5898 newborns with weight over 500 g were examined. 341 histories of development of newborns with malformations were analysed. Statistical calculations were performed using Chi square test. RESULTS: It was stated, that the percentage of malformations was 5.8% in examined period with 1.6% of severe malformations in it. Malformations of genitourinary, osteoarticular and circulatory systems were of the most frequent occurrence. Frequency of intrauterine hypotrophy in newborns with malformations was statistically significantly higher than in the group of all examined infants. CONCLUSIONS: Hypotrophy is to a higher degree than prematurity connected with the hazard of presence of congenital malformation. Considering constant increase of the number of malformations which was shown in this paper, there is urgent necessity of introducing of the comprehensive registry of malformations in Upper Silesia.
