Brief Summary: This prospective cohort study measured day 3 serum calcium and 25OH vitamin D (25OHD) in 1002 mother-newborn pairs to establish reference ranges in vitamin D replete babies.Calcium declines in the first days of life and is frequently measured in the neonatal nursery, not only for symptomatic newborns but also for conditions such as prematurity, low birth weight or maternal diabetes mellitus. French guidelines recommend an oral bolus of Vit...

Brief summary: Over the recent years several publications reported on next generation sequencing (NGS) in cohorts of patients with congenital hypothyroidism (1). Based on these data, diagnostic yield was higher in patients with gland-in-situ, than with thyroid dysgenesis. Further studies performed NGS only in cohorts of patients with gland-in-situ, excluding thyroid dysgenesis forms such as athyreosis, ectopy, or hypoplasia (2). The publication of Levaillant ...
