3. Thyroid

A Stoupa , G Szinnai

A selection of papers with high impact challenging current knowledge and practice in pediatric thyroidology were published during the last year. On the molecular level, the proof of intracellular compartmentalization of the TSH/TSHR signaling cascade changes our view on TSH/TSHR signaling adding an new level of regulation. On the hormonal level, the fact that thyroid hormones regulate cardiac function and metabolic activity mainly by a noncanonical thyroid hormone receptor ind...

A Galderisi , D Kariyawasam , A Stoupa , AN Quoc , G Pinto , M Viaud , S Brabant , J Beltrand , M Polak , D Samara-Boustani

Brief Summary: This study investigated daily glucose patterns in young children with classic congenital adrenal hyperplasia (CAH) and their relation with hormonal circadian rhythm.Comment: The aim of treatment in classical CAH is to provide adequate glucocorticoid and – when necessary – mineralocorticoid replacement to prevent adrenal crises and suppress excess adrenal androgen production. Glucocorticoids regulate glucose homeostasis, and patie...

Brief Summary: This single-centre retrospective cohort study offers valuable insights into the trajectory of weight gain in a paediatric craniopharyngioma cohort over a mean follow-up period of 10.4 years, reinforcing the necessity for targeted interventions to address this issue.Craniopharyngioma poses a substantial clinical challenge in paediatric patients, primarily due to the risk of hypothalamic involvement. A particularly severe long-term consequen...
