Title: Congenital anomalies associated with congenital hypothyroidism. Author: Stoll C, Dott B, Alembik Y, Koehl C. Journal: Ann Genet; 1999; 42(1):17-20. PubMed ID: 10214503. Abstract: The French national neonatal screening program for congenital hypothyroidism (CH) was initiated in 1978. The purpose of this study was to ascertain the incidence of congenital extrathyroid anomalies (ETAs) among the infants with congenital hypothyroidism (CH) and to compare it with the Northeastern France Birth Defect Monitoring System data from 1979 to 1996. Among 129 CH infants on whom adequate data were available, 20 infants (15.5%) had associated congenital anomalies. Eight out of 76 infants with persistent CH had ETAs (10.5%) whereas 12 out of 53 children with transient hypothyroidism had ETAs (22.6%, p < 0.05). Some additional anomalies were considerably more common than in the general population. Nine infants had congenital cardiac anomalies (6.9%). This rises the question if teratogenic effects active during organogenesis may affect simultaneously many organs, including the developing thyroid, causing a relatively high percentage of CH infants with congenital ETAs.[Abstract] [Full Text] [Related] [New Search]
