Facial anthropometric measurements in offspring of epileptic mothers

RESUMO

Background. Minor facial anomalies in 14-33 percent of exposed fetuses have been associated with the teratogenic effect of antiepileptic drugs (AED) since 1968. The purpose of this article is to describe the facial characteristics ofoffspring of non-epileptic women previously describen in the literature, and to correlate the facial anomalies with the specific drug. Methods. An interval was defined where 95 percent as "uncommon values" (UV) or as being in the "alert zone"; the odds ratio with Wolf modification was used and then Fisher's tes for comparison with healthy newborns. Full-term eutrophic newborns of epileptic mothers who received attention at the epilepsy clinic of a gyneco-obstetric center were included. Results. During the study period, 72 eutrophic, full-term newborns were included; in 70 cases at least one measurement was found in the alert zone, with a predominance of the mid-line area. No differences were found between neonates who received monotherapy vs. polytherapy. The groups exposed to phenobarbital, clonazepam and multiple AED showed more uncommon values (p <0.05), identified as minor dysmorphisms by other authors. It seems to be a particulat susceptibility of the mid-line of the face to show the effects of AED and, additionally, of environmental agents. Conclusions. No differences were found in the facial values among the different AED used in monotherapy form. It is suggested that the choice of drug used during pregnancy must be decided on according to the clinical dignosis of each mother's epilepsy, and not on the basis of ptential teratogenic risk
