Abstract
The data processing of multiple congenital abnormalities [CA] is demonstrated in the Hungarian Surveillance of Congenital Anomalies. Specified dysmorphic syndromes and CA-associations are registered on the basis of notification. Unspecified multiple congenital abnormalities are evaluated on the basis of notified abnormalities. First, a distance-diagnosis is being tried concerning some specified dysmorphic syndromes and CA-associations. Second, the alive babies with unspecified multiple abnormalities are referred to the regional multiple abnormality center while a detailed post-mortem description is requested from the stillborns and infant deaths with multiple abnormalities. Third, the remaining unspecified congenital abnormalities are divided into 4 categories (obvious, important, dubious and minor) and into 40 groups. Babies with 2 abnormalities are annually compiled in 1 table. Babies with 3 abnormalities are summarized according to the so-called cardinal abnormalities in different tables. Finally, babies with .gtoreq. 4 abnormalities are listed one by one with regard to the leading abnormality in another table. This classification system helps recognize known and new syndromes and CA-associations and helps monitor a cluster of specific combinations of congenital abnormalities.
