Chondrodysplasie ponctuée et intoxication alcoolique maternelle: à propos de 7 observations

: The authors report 7 cases of chondrodysplasia punctata in whom maternal alcohol intoxication was found. Most often, it consisted of chronic and confirmed alcoholism, except for the last case, in which an acute intoxication had occurred at about the 4th or 5th week of pregnancy. Clinically, the appearance of the children was evocative of fetal alcohol syndrome, except in the last case when, in contrast, the facial dysmorphy was very typical of chondrodysplasia punctata. The skeletal anomalies preferentially involve the lower limbs, sometimes the sacrum, and in one single case, the dorsal spine. Upper limbs are always spared. The maternal hepatic lesions may be responsible for the skeletal impairment, due to their repercussion on the metabolism of vitamin K. This skeletal impairment would then be close to that induced by treatments with warfarin during pregnancy. Whatever, it is absolutely necessary to X-ray the lower limbs in cases with fetal alcohol syndrome, in order to not overlook associated bone lesions.
