Background: Girls with Turner Syndrome (TS) are at an increased risk of primary ovarian failure. Oestrogen replacement is commenced at around the age of 12 years, in girls who do not enter puberty spontaneously, with incremental changes to the dose over the next 3 years until adult replacement doses are achieved. We have previously shown good correlation between serum and urinary LH (uLH) and FSH (uFSH) in children being assessed for disorders of puberty.<...

Background: Hypoglycaemia is one of the most common presenting complaints at paediatric emergency department. There are many distinct causes of hypoglycaemia, ranging from nutritional insufficiency, infectious origins, to metabolic disorders. A thorough investigation can help differentiate the cause of hypoglycaemia, with subsequent tailored management. All patients with hypoglycaemia should have a full clinical assessment and together with a hypoglycaemia scr...

Background: Silver Russell syndrome (SRS) is a rare imprinting disorder with prenatal and postnatal growth retardation and feeding difficulties. The main molecular causes are loss of methylation of the 11p15.5 imprinting control region (H19/IGF2) and maternal uniparental disomy of chromosome 7. Prader-Willi syndrome (PWS) is a complex neurodevelopmental imprinting disorder with neonatal muscular hypotonia, failure to thrive to insatiable appetite, sho...

Background: Early treatment of neonatal diabetes with sulfonylureas has shown to improve neurodevelopment, beyond the demonstrated efficacy on glycemic control. Several barriers still prevent its use as an early treatment in preterm babies including the limited availability of a suitable galenic form of glibenclamide. Recently, an oral suspension of glibenclamide (Amglidia®) has been approved for use in EU.Methods: W...

Background: Steroidogenic Factor 1 (SF-1), encoded by NR5A1 (Nuclear receptor subfamily 5 group A member 1) gene, is a transcriptional factor that is primordial for adrenal and gonadal organogenesis. Pathogenic variants of NR5A1 are responsible for a wide spectrum of phenotypes with autosomal dominant inheritance, from adrenal insufficiency to gonadal dysgenesis and oligospermia-azoospermia in 46,XY patients.Obj...

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...

Background: Emerging evidence suggests a link between the intestinal microbiota and cardiometabolic outcomes in both children and adults. The oral microbiota is less studied, and the association between the oral microbiota and cardiometabolic health in childhood remains largely unknown.Objective: To explore the associations between oral microbiota diversity measured at 8-10 yr and cardiometabolic health in childhood and ...

Background: Severe primary insulin-growth factor-1 (IGF-1) deficiency (SPIGF1D) is a rare cause of growth retardation. Diagnostic criteria include age- and sex-dependent low basal IGF-1 levels (<2.5th percentile), height ≤ -3SDS, absence of growth hormone deficiency and of any secondary causes of growth failure.Objectives: Description of pubertal onset and growth spurt, data on adult or near-adult-he...

Background: Oral microbiota composition and diversity differ between obese and non-obese individuals. However, the associations between lifestyle habits (implicated in the pathogenesis of obesity) and the oral microbiota remain uncertain, particularly among children.Objective: To explore the associations between oral microbiota diversity and lifestyle habits among 8-10 year-old children.Met...

Background: Protein intake is crucial for growth. Many inherited metabolic diseases (IMD) require a strict controlled protein diet.Aim: to evaluate growth, pubertal status and body composition in IMD requiring a strict controlled protein diet.Patients & Méthods: Longitudinal follow up cohort study. We recorded data before 4years (early childhood, n=189); betwe...
