Background: French health authorities have developed a national program to organize outpatient care networks for the prevention and management of obesity in children and adolescents (Réseau de Prise en Charge de l’Obésité Pédiatrique (REPOP)). To date, REPOP Ile-de-France has more than 250 primary care physicians with dietitians, nurses, educators, and psychologists trained in the management of childhood obesity as part of a standard care pathway, work...

Background: In monogenic diabetes due to KCNJ11 and ABCC8 mutations that impair KATP- channel function, sulphonylureas improve long-term glycaemic control. Although KATP channels are extensively expressed in the brain, the effect of sulphonylureas on neurological function has varied widely. We evaluated published evidence about potential effects of sulphonylureas on neurological features, especially epilepsy, cognition, motor function and muscular tone, visuo-...

Hypochondroplasia (HCH) is a skeletal dysplasia, mainly caused by mutations in the fibroblast growth factor receptor3 (FGFR3) gene and characterized by disproportionate short stature.Our main was to determine the efficacy of growth hormone therapy in children with HCH, compared with a historical cohort of 40 untreated children with HCH.Diagnosis of subjects was confirmed by the Bone Dysplasia Center2. Height standard dev...

Background: Adolescence is often a period of worse metabolic control and less wellbeing in diabetic children. We studied global (GW) and diabetic-related (DRW) wellbeing in diabetic adolescents and the influence of sex, age, ethnic origin, family composition (single- or two-parent family), family income and metabolic control.Method: 133 (71 girls, 120 autochthonous, 20 treated with CSII, 107 from a two-parent family, 68 from families with a monthly incom...

Context: Specific references for height, weight and BMI that consider the maturation tempo for onset of puberty are lacking worldwide.Aim: To fill the gap, by developing specific pubertal references for heightSDS, weightSDS and BMISDS, all aligned for the individual onset of puberty.Method: Reference population: a subgroup of GrowUp1990Gothenburg cohort of 1572 (763 girls) health...

Background: Individuals with congenital adrenal hyperplasia (CAH), a form of adrenal insufficiency, are exposed to daily non-physiologic, non-circadian cortisol profiles due to both the disease and therapeutic limitations. Dysfunction in the hypothalamic-pituitary-adrenal axis is strongly associated with depressive disorders. However, little is known about the prevalence of depression among children and young adults with CAH. We investigated the prevalence of ...

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: 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...

Background: Congenital hypothyroidism is primarily due to thyroid dysgenesis (TD). The genes implicated in TD, account for a small number of patients with monogenic forms, less than 5%. Borealin is a major component of the Chromosomal Passenger Complex, an essential regulator of mitosis.Objective and hypotheses: To understand the role of Borealin mutations found in patients with TD.Method: We performed whole exome sequencing (WES) ...

Background: Sulfonylurea therapy (SU) allows a better metabolic control than insulin in patients with neonatal diabetes secondary to mutation in potassium channel subunits (ND-K). Most of these patients have neurological and neuromotor developmental impairments whose changes under SU has not been studied in a systematic and prospective way in a large cohort.Objective and Hypotheses: To demonstrate the beneficial effect of SU on neuropsychological functio...
