Aims: The golden standard to characterize pubertal maturation is the analysis of steroid hormones in the blood. The aim of the investigation was to assess whether the analysis of salivary steroids is similarly able to characterize male pubertal development.Methods: The investigation included 165 normal boys (mean age 12.7±2.8 years, mean body mass index 19.6±4.2 kg/m2). Pubic hair stages were stratified by Tanner and testicular volum...

Background: Congenital hyperinsulinism is the most common cause of persistent hypoglycaemia in early infancy. Mutations in the HNF4A gene lead to transient hyperinsulinism in early infancy and maturity-onset diabetes of youth (MODY1), later in life. Fanconi syndrome is a generalised dysfunction of the renal proximal tubule with a loss of glucose, amino acids, phosphate, low molecular weight proteins, bicarbonate and urate, causing growth failure and rickets in childho...

Background: Disproportional short stature (DSS) is the most frequent clinical presentation of skeletal dysplasias, which are a heterogeneous group of more than 450 disorders of bone. Skeletal survey is important to establish the diagnosis and to guide the genetic test, but has several limitations, especially in mild and atypical cases.Objective and hypotheses: To identify the genetic aetiology of DSS by exome sequencing.Method: Who...

Introduction: Premature pubarche is the most frequent diagnosis when children present moderate pubic hair development, but other diagnosis must be ruled out. We report the case of a child with premature pubarche with hormonal results in the physiological range, corresponding to an adrenal tumor.Observation: A girl aged 6.8 years consulted for precocious pubertal development (pubic hair stage 3, breast stage 2), with moderate acne. There was no virilizati...

Background: The SCOPE French retrospective study follows children affected with growth hormone (GH) disorders treated with recombinant human GH (r-hGH) therapy via the easypod® connected injection device for up to 5 years.Aim: To show the results from an interim analysis of the SCOPE study analysing adherence to r-hGH therapy in a real-world setting and its effect on catch-up growth.Met...

Background: 17-hydroxyprogesterone (17-OHP) basal levels greater than 2ng/ml has been related to the need to request an ACTH test to dismiss non-classic congenital adrenal hyperplasia. We have seen an increase in baseline levels in 2021 compared to 2020.Objectives: To determine how many of the tests that were requested due to a high basal 17-OHP value, were positive. Assess the need to modify the cut-off points to reques...

Introduction: Hirsutism is a condition defined as excessive male-pattern hair growth in females most commonly caused by hyperandrogenism. Polycystic ovary syndrome (PCOS), non-classic adrenal hyperplasia (NCAH) due to 21-hydroxylase deficiency and androgen-secreting tumors represent causes of androgen excess. Common features such as hirsutism, polycystic ovaries, oligomenorrhea or amenorrhea, and insulin resistance make it hard to distinguish between the first...

Background: Bardet-Biedl syndrome (BBS) causes early-onset extreme obesity and hyperphagia that is hypothesized to arise from leptin receptor dysfunction. Setmelanotide, a melanocortin-4 receptor (MC4R) peptide agonist, has been shown to induce weight loss in individuals affected by other rare genetic obesity disorders resulting from leptin-melanocortin pathway dysfunction upstream of MC4R.Objective: Report preliminary data on body weight, hunger scores,...

Background: The peptides obestatin and adropin are thought to regulate glucose and lipid metabolism, weight gain, and fluid intake in adults. The roles of obestatin and adropin in the regulation of weight and glucose and lipid metabolism in Prader-Willi syndrome (PWS) and non-syndromic pediatric obesity are poorly understood. This study compares the concentrations of obestatin and adropin in infants and children with PWS and age- and BMI-z matched controls, and explores the as...
