The growth hormone (GH)-insulin-like growth factor (IGF-1) system is essential for optimal human growth and energy homeostasis. Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a protease involved in the liberation of free IGF-1, leads to problems in growth and bone density in humans and mice. Patients with PAPP-A2 deficiency also present lower body mass and mild glucose intolerance. The present study aimed to determine the influence of 1 month of high carbohydr...

For the brain tumor committee of SFCE (Société Française des Cancers de l’Enfant).Objective: Therapeutic approach favors chemotherapy as the first-line-treatment in progressing OPG. There are few data on long term endocrine outcomes of aggressive OPG treated by upfront chemotherapy. Our main objective was to describe the long-term endocrine sequelae in these patients and to identify potential early predictors of the endocrine involvem...

Background: The genetic etiology of non-syndromic HI remains unknown in over 20% of all cases, and over 50% of diazoxide-responsive cases. Non-coding variants in HK1 have been suggested to cause HI by linkage-analysis (Pinney et al., 2008). More recently, variants within a regulatory region of HK1 intron 2 were reported in 17 individuals with HI (Wakeling et al., 2022). These variants have been proposed to cause HI by disrup...

Background: Cantù syndrome is a rare disorder characterized by congenital hypertrichosis, neonatal macrosomia, a distinct osteochondrodysplasia, and cardiomegaly. Other findings described are vascular abnormalities, pulmonary hypertension, generalized edema, mild learning disability and behavioral problems. Cantù syndrome is related to an heterozygous pathogenic variant in ABCC9 or KCNJ8, which can be inherited in an autosominal dominant manner or d...

Background: Congenital hyperinsulinism (CHI) is a common cause of hypoglycaemia in neonates, infants and children. CHI is a heterogeneous disease in terms of clinical presentation, genetics and histology.Objective and hypotheses: The aim of this study was to describe the clinical characteristics, genotype–phenotype correlations and treatment outcome of Russian patients with CHI.Method: A total of 90 children with CHI were iden...

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...

Introduction: Infants whose weight is > the 90th percentile for gestational age are classified as large for gestational age (LGA). Catch-up and catch-down growth can be defined as an increase or decrease in WAZ by > 0.67 SD respectively during the infantile period. It was suggested that in LGA rapid catch-up and/or no catch-down during infancy may be associated with the development of overweight (OW) and obesity (OB) during childhood.<p class="abstex...

Introduction: Large for date (LGA) infants may have a higher tendency to become obese and tall. Catch-up and/or catch-down in linear growth, defined as an increase or decrease in length for age Z score (LAZ) by > 0.67 SD during the infantile period, may affect this tendency. Additionally, head circumference is well correlated with brain growth.Aim: We evaluated the prevalence of tall stature (LAZ > 1 and> 2) and...

Background: Celiac disease (CD) is an important association with type 1 diabetes (T1DM) with a significant impact on growth and glycaemic control. The frequency of coexistence of T1DM and CD is widely described, ranging from 2.5 to 16.4% in 23 studies worldwide, much greater than the general population risk of 1%. The risk of CD is higher among younger children (less than 4 years), females and during the first few years of T1DM diagnosis. Objectives: We aimed ...

Introduction: Small size at birth is only a proxy for the pathological process of intrauterine growth restriction.Aim: To study the effect of different birth weights on postnatal growth.Method: We studied the linear growth of 59 infants who were born preterm (GA = 33.5 +/- 2.2 weeks) with birth weight >1.5 < 2.5 kg) for two years. They were classified at birth into two groups...
