Background: Metabolic syndrome and insulin resistance are well recognized in adult obesity. Their criteria and prevalence and are still controversial in children.Objective and hypotheses: To evaluate the prevalence and natural history of clinical and biological parameters of the metabolic syndrome in a pediatric cohort of obese subjects. To identify metabolically healthy subjects and the persistence of this phenotype over time.Meth...

Background: Non-idiopathic central precocious puberty (CPP) is caused by acquired or congenital hypothalamic lesions visible on magnetic resonance imaging (MRI), or associated with various complex genetic and/or syndromic disorders without visible lesions on MRI. We investigated the different types and prevalences of non-isolated CPP phenotypes in a large group of consecutive patients with CPP.Methods: This observational cohort study included all patient...

Background: An increase in the incidence of congenital hypothyroidism (CH) with a normally located gland has been reported worldwide. Affected individuals display transient or permanent CH during follow-up in childhood. We aimed to determine the prevalence of transient CH and to assess the possibility of distinguishing between transient and permanent CH in early infancy.Methods: This observational cohort study included all patients identified by systemat...

Background and Objectives: Chronic administration of synthetic glucocorticoids affects 1% of the world population and is responsible for secondary adrenal insufficiency for 40% of the patients. In pediatrics, glucocorticoid-induced adrenal insufficiency (GI-AI) diagnosis is based on the Low Dose Synacthen Test (LD-SST). Screening for glucocorticoid-induced adrenal insufficiency implies medical and economical costs due to the necessity of an intravenous line an...

Background: Final results from MEGHA study required by Health French Authorities (HAS).Objective and hypotheses: Objectives are to carry out longitudinal follow-up during maximum 5 years of AGHD patients treated with Saizen, with a description of prescription modalities, demographic and clinical characteristics, patient compliance, product safety, and quality of life.Method: MEGHA is a multicentric study, with prospective follow-up...

Background: Renal tubular acidosis (RTA) is an uncommon cause of growth failure and rickets. In Haiti, diagnostic evaluation and management is challenged by limited access to comprehensive diagnostic tools.Case presentation: An 8-year-old Haitian girl was evaluated at an academic referral center for bony deformations and bone pain, progressive over the previous six years. Her 2.5 year-old sister presented similar symptoms, associated with dental caries a...

Background: Genetic females with congenital adrenal hyperplasia (CAH) from severe 21-hydroxylase deficiency may be declared at birth as cryptorchid boys. Neonatal salt wasting leads to early reassignment but in its absence, the condition may go unrecognized.Case presentation: A term newborn with non-palpable gonads but a penile urethra was declared as boy. At 4.8 years, the child presented with sexual precocity. Height was +2.3 S.D., penil...

Background: The age of onset of puberty varies from country to another and, within every country, from one socioeconomic group to another. In Sub-Saharan Africa, particularly in Cameroon, there is paucity of data on this topic.Objective and hypotheses: To determine clinically meaningful normative reference data that describe the timing of sexual maturity indicators among Cameroonian children and to determine factors that influence the onset of this matur...

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: Treatment of childhood and adolescent obesity is rarely effective if “cure” i.e., BMI below the obesity range, is used as the definition of success. However, results of obesity treatment is much more effective if treatment is initiated in 6–7 years old children. It is therefore urgent to develop interventions for young children, both preventive and obesity treatment efforts. Results from such interventions as well as preliminary results from ongoing ...
