[Correlations between pregnancy pathology, study of the placenta, antenatal echography and examination of the product of conception in a series of 175 congenital malformations]. / Corrélations entre la pathologie gravidique, l'étude du placenta, l'échographie anténatale et l'examen du produit de conception dans une série de 175 malformations congénitales.

In order to verify the hypothesis that during pregnancy in a woman without peculiar history, signs could be discovered when the fetus is malformed we have reviewed the files of 175 women who had a malformed child and of 300 controls. All of these women had at least one clinical examination and one ultrasonographic examination during pregnancy. Two clinical symptoms were more often discovered in the mother of the malformed fetus (p less than 0.001): decrease of fetal movements and small for date fetus. The placenta is never abnormal in the mother with normal fetus. Placenta is abnormal in 31% of the mother with malformed fetus but the abnormalities are not specific. Ultrasonographic examinations allowed more often the discovery of a malformation when hydramnios (p less than 0.001) or fetal hypotrophy (p less than 0.01) or an anomaly of the morphology of the fetus is discovered. Accuracy of prenatal diagnostic is considered for the different categories of congenital malformations.

[The value of current echographic parameters in fetal biometry]. / Valeur des nouveaux paramètres échographiques de biométrie foetale.

A review of current literature concerning developments of new parameters in fetal biometry is presented. To be sure, these parameters are very useful for detection of fetal malformations but outside of femoral length they do not contribute more valuable information than the already accepted parameters for determination of gestational age or detection of disorders of fetal growth.

[Epidemiologic factors in ovarian cancer]. / Facteurs épidémiologiques des cancers de l'ovaire.

Ovarian carcinoma is the most severe gynecological cancer with an overall incidence of 12 per 1000 Americans or Europeans developing it over 40 years of age. Only 3 of the 12 cases will receive efficient care because the diagnosis will be made too late. This study reveals the principal risk factors i.e. upper socioeconomic echelon, ovarian function uninterrupted by a pregnancy or usage of oral contraceptives, anamnestic evidence of ovarian carcinoma in the family, some hereditary disorders, external insults (talcum powder). The synthesis of these various risk factors permits a comprehensive review of the hypotheses of pathogenesis concerning recurrence of tumors. But corollary epidemiologic studies are still needed to try to define better the high risk groups whose follow-up systematic detection and testing is a priority.
