Background: For adult patients who do not meet indications to surgery, the calcimimetic cinacalcet is approved for primary hyperparathyroidism (HPT), decreasing calcium and parathyroid hormone (PTH) levels. This drug is largely used in adults, but may be a challenge in daily practice in children, because of the risk of hypocalcemia, increased QT interval and drug interactions. A few pediatric cases have highlighted its potential interest in children with HPT; ...

Introduction: XLH is caused by mutations in PHEX leading to increased FGF23 levels, phosphate wasting, and impaired endogenous calcitriol synthesis. Affected patients present with rickets and diminished growth velocity during childhood, and osteomalacia and short stature in adulthood. Adult height is linked with health within and across generations suggesting that adult height may be a potential tool for monitoring health conditions, e.g., XLH.<p ...

Introduction: Congenital Lipoid Adrenal Hyperplasia (CLAH) is a severe deficiency of adrenal and gonadal steroidogenesis, caused by mutations in the StAR gene and the accumulation of cholesterol in the outer mitochondrial membrane due to steroidogenic acute regulatory protein (StAR) deficiency. Affected patients present peripheral adrenal insufficiency with early onset, and variable phenotypes at the age of puberty.Objective of o...
