Background: The pathophysiology of the increased fracture risk in Type 1 Diabetes Mellitus (T1DM) remains unclear.Objectives: Perform multimodality assessment to determine the effects of T1DM on bone health and fractures.Methods: Thirty-two children with T1DM at a median (range) age of 13.7 years (10.4, 16.7), and median HbA1c 65mmol/mol (27,100) were recruited. Serum bone alkaline phosphatase (BAP) and c-terminal telopeptide type ...

Background: Obesity in childhood and adolescence represents a major health problem of our century that has reached epidemic proportions globally during the last decades. In obese subjects, a relatively high cortisol output in urine has been observed compared to nonobese individuals. However, cortisol concentrations in blood, saliva, and urine in association with obesity have not been consistent across studies. Hair cortisol concentrations (HCC) determined in scalp hair provide...

Background: Turner Syndrome (TS) with a 45,X phenotype is generally more severe than TS with mosaicism, but the potential role of the degree of mosaicism in modulating TS phenotype has never been investigated. We assessed the impact of various degrees of 45,X/ 46,XX mosaicism on phenotypic features in a cohort of TS patients.Method: We analysed a cohort of TS with 45,X/ 46,XX mosaicism (percentage mosaicism from peripheral blood lymphocytes, known in <em...

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: 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...
