Thyroid function in preterm infants admitted to the neonatal intensive care unit: a single center study

Nicolas Georges , Achkar Joy , Akiki Simon

Background: A common cause of neurodevelopmental impairment in children is congenital hypothyroidism, but can be preventable with adequate screening and proper management. Preterm newborns are more likely to have thyroid dysfunction, with small for gestational age (SGA) being an additional risk factor. However, only few studies addressed the altered thyroid hormone concentrations in the first few weeks of life concluding that Thyroid-Stimulating Hormone (TSH) levels are higher...

We report a term male with diazoxide-unresponsive congenital hyperinsulinism (CHI) (spontaneous conception, non-consanguineous, no family history). The patient did not have macroglossia, exomphalos or lateralised overgrowth (cardinal Beckwith-Wiedemann spectrum (BWSp) features) (1). There was no polyhydramnios, macrosomia, facial naevus simplex, ear creases/pits, diastasis recti or nephromegaly/hepatomegaly (suggestive BWSp features) (1).A targeted massi...

Background: We recently identified loss-of-function mutations in makorin ring finger 3 (MKRN3) as a cause of familial central precocious puberty (CPP). Analysis of Mkrn3 expression in the arcuate nucleus of mice showed high expression levels in juvenile mice, with a marked reduction prior to puberty onset, suggesting that MKRN3 inhibits puberty initiation. The function of MKRN3 is not known but based on its amino acid sequence, it is predicted to act as an ubiquitin l...
