[Registration of congenital malformations in Paris. Evaluation and perspectives of a study carried out under the auspices of the European Economic Community].

Since 1976 a registration of congenital malformations has been gradually set in Paris. At present it covers 95% of the births registered in this department which amount to 38,925 births in 1982. Since 1981, it has been extended to include malformations diagnosed during the first month of life in neonatal units in Paris, for residents in Paris, and also a register of therapeutic abortions for congenital abnormalities. It is part of the 17 registers which have been started on the initiative of the European Economic Community. The results of the frequency of different types of congenital malformation are given for the years 1978 to 1982. The value of this register as epidemiological information and the studies that have been carried out with a view to determining aetiology are discussed.
