There is a recent renewed interest in vitamin D metabolism and pathophysiology, due to its recent description as a hormone with a positive impact on global health rather than a strictly bone hormone: vitamin D could be a protective factor against infection, autoimmunity, cardiovascular morbidity, and cancer. By contrast, vitamin D deficiency appears to be increasingly frequent worldwide. We propose a review of these new aspects of vitamin D metabolism, with a focus on vitamin D status in a local pediatric cohort. There is an urgent need for revisiting current guidelines on vitamin D supplementation and for closely monitoring serum vitamin D in children with chronic diseases, i.e., at greater risk of cardiovascular impairment, bone morbidity, infectious disease, and acute inflammation.

Screening for sickle cell disease, the most common of recessive autosomic hemoglobin disorders, allows detection of sickle cell disease SCD (homozygous sickle cell disease, compound heterozygote SC, and S β-thalassemia) in a target population. Our objective was to evaluate its effectiveness at the Nice University Hospital. ⋯ Screening for sickle cell disease appears effective in Nice. It seems necessary to continue focusing on the importance of screening among maternity healthcare actors.

The mythology of the Greeks and Romans is full of monsters of fiction: giants, cyclops, centaurs, hydras, Gorgons… The accounts of travelers, reproduced in the Natural History of Pline l'Ancien reported the existence, in distant countries, of men with a dog's head (baboons), of men with a single tall foot (sciapode), beings whose face is embedded in the chest (or acephala blemmyes), to which must be added a wide variety of men with no mouth, no nose, or equipped with giant ears or feet turned backwards, as well as hermaphrodites. Teratology reports on monstrous births, which have constituted the factual basis from which the imagination conceived adults whose morphology corresponds to the monsters of legend. Newborns sirenomelia were behind the legend of sciapode and sirens. ⋯ The acardiac fetus may explain some monstrous forms, features the work of Hieronymus Bosch. The significance of the monsters of legend, their genesis, their persistence through the ages is complex. By approaching teratology, we added a new field of exploration of real monsters of antiquity and Middle Ages.
