To read the full abstract: J Clin Endocrinol Metab. 2019;104:5765–5779.It is not clear whether retesting is needed for a healthy cotwin of a twin pair discordant for congenital hypothyroidism (CH) at the first neonatal screening. Medda et al. retrospectively analyzed a cohort of 47 twin pairs discordant for CH at the first neonatal screening. On follow-up, 7 (15%) of cotwins who were initially negatively screened then tested positi...

However, the long-term outcome on offspring metabolic, somatic and cognitive health has raised significant concern. In rodents, high glucocorticoid levels inhibit development of beta cells during fetal life and lead to...
