Background: Neonatal vitamin D deficiency (VDD) can result in symptomatic hypocalcemia, seizures and cardiomyopathy and has been associated with reduced bone mineralization in childhood, but is potentially preventable with antenatal cholecalciferol supplementation. Single nucleotide polymorphisms (SNP) in the vitamin D metabolism pathway are associated with serum 25-hydroxyvitamin D [25(OH)D] in adulthood. We assessed whether maternal and/or offspring SNPs in ...

Introduction: The melanocortin 4 receptor (MC4R) is a G protein coupled receptor (GPCR) and plays a pivotal role in the central regulation of body weight in the hypothalamus. In the context of the leptin-melanocortin signaling pathway, the MC4R is activated by the endogenous ligands a- and b-MSH (melanocyte-stimulating hormone). This leads to the feeling of satiety and to a reduction in food intake. Mutations within the genes leptin, leptin receptor (LEPR), pr...

Background and Aims: Central Precocious Puberty (CPP) caused by the early activation of the hypothalamic-pituitary-gonadal axis is a rare affection that occurs in 0.2% in girls. Clinical signs are suggestive and LHRH-test could be sometimes difficult to use and not always contributive. Gonadotropin assay in twenty-four hours-urinary collection could be an interesting option. The present work intended to evaluate the diagnostic interest of 24-hour urinary gonad...

Executive function, intelligence and bone mineral density: Do associations exist in childhood?

Background: In later life, osteoporosis and poor cognitive function often co-exist. This has commonly been attributed to post-menopausal estrogen loss, but there is increasing recognition of cross-talk between the brain and bone. For example, in animal models, bone derived osteocalcin has positive associations with brain volume and cognitive function whilst brain-derived neurotransmitters appear to influence bone mass. Despite this, a common early life origin ...

Introduction: Congenital hyperinsulinism (CHI) is the commonest cause of severe hypoglycaemia in early childhood but glycaemic characterisation remains scarce. Continuous glucose monitoring (CGM) offers a deep understanding of glycaemic control to understand disease burden, individualise patient care and inform therapeutic trials in CHI. Preliminary studies suggest inadequate accuracy and no efficacy of standalone CGM to reduce hypoglycaemia. Provision is hist...

Background: Pancreas transcription factor-1 alpha (PTF1A), encoded by the PTF1A gene, is a beta helix loop(bHLH) protein which involved in the development of the pancreas and cerebellar neurogenesis. Although mutations of PTF1A cause permanent neonatal diabetes(PNDM), pancreas agenesis and cerebellar agenesis, PTF1A enhancer mutations reported causing PNDM and isolated pancreas agenesis. In the present study, we evaluate the phenotyp...

Introduction: Parathyroid Hormone (PTH) is one of the principal regulatory hormones for calcium and phosphate homeostasis. Reduced PTH concentration in hypoparathyroidism is characterised by hypocalcaemia and hyperphosphataemia.Case Presentation: We report a ten-year-old girl who was admitted to the Department of Paediatrics, Endocrinology, Diabetology with Cardiology due to repeated seizures, hypoalcaemia with suspected...

Background: Neonatal Diabetes Mellitus (NDM) is a rare form of monogenic diabetes that typically presents during the first 6 months of life. Its prevalence is about 1:100 000 live births; however it may rise up to 1:29 000 in highly consanguineous populations. Mutations in 22 different genes are reported; with the most common cause being potassium channel subunit gene (KCNJ11/ABCC8) mutations. However, causative mutations among consanguineous populations seem to diffe...
