Thyroid dysgenesis accounts for 75% of all cases of congenital hypothyroidism (CH), and includes thyroid agenesis or hemiagenesis, thyroid hypoplasia, and thyroid ectopy. Thyroid transcription factors TTF-1, TTF-2 and Pax-8, which are involved in the development of the thyroid gland and its normal migration, have been indicated as the best candidate genes but have been found to be mutated in a minority of cases. Sonic Hedgehog (Shh) protein is involved in several key events du...

Background: The initial L-T4 dose in the treatment of congenital hypothyroidism (CH) currently recommended is 1015 mcg/kg/die.Objective: We designed a multicenter randomized trial to evaluate the effects of different starting dose of L-T4 within the range 1015 mcg/kg/die on neurocognitive development in children with CH.Methods: Seventy-two children with CH diagnosed by neonatal screening were enrolled in the study. The...
