Congenital Hypothyroidism (CH) is the most common congenital endocrine disease and avoidable cause of severe mental retardation. The CH pathogenesis may include the contribution of genetic and environmental factors. However, causal mutations have been found in a minority of cases. Moreover, the elevated frequency of discordance for CH phenotype between monozygotic (MZ) twins suggests the involvement of non-Mendelian mechanisms. Aim of this study was to investigate the role of ...

Background: The initial L-T4 dose in the treatment of congenital hypothyroidism (CH) currently recommended is 10–15 mcg/kg/die.Objective: We designed a multicenter randomized trial to evaluate the effects of different starting dose of L-T4 within the range 10–15 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.
