Introduction: Congenital adrenal hyperplasia (CAH) is most often caused by 21-hydroxylase deficiency (21OHD: 95%) or by 11-hydroxylase deficiency (11OHD). Classic CAH results in impaired cortisol production and consequently elevated ACTH concentrations leading to chronic adrenal stimulation with strongly elevated adrenal steroid precursors before the enzymatic defect. In contrast to other forms of adrenal insufficiency, some untreated classic CAH patients seem to have less cli...

Background & Aims: Children with acute lymphoblastic leukemia (ALL) frequently receive high doses dexamethasone during treatment, which may induce acute side effects. The aims of the current study were to determine the influence of a five-day dexamethasone course on changes in leptin, fat mass, body mass index (BMI), hunger, sleep and fatigue and to explore the associations between these changes.Methods: Pediatric AL...

Introduction: Children with cancer are at increased risk of endocrine complications, especially children with a brain tumor. One of these late effects includes bone disorders (ranging from low bone mineral density (BMD) to osteoporosis). Children with a suprasellar Low Grade Glioma (LGG) may be especially at risk for bone problems due to exposure to multiple treatment modalities, hypothalamic dysfunction and/or decreased mobility in combination with vision los...
