La puberté précoce est définie comme le développement des caractéristiques sexuelles avant l'âge de 8 ans chez les filles et de 9,5 ans chez les garçons. L'objectif de notre étude était de calculer la prévalence de la puberté précoce en consultation spécialisée et de décrire le profil clinique, paraclinique, étiologique et de prise en charge ainsi que la qua...

Background: Congenital adrenal hyperplasia, one of the most frequent autosome recessive disorders, is caused by defects in steroidogenic enzymes involved in the cortisol biosynthesis. Approximately 95% of cases are caused by a deficiency of the 21-hydroxylase enzyme. Its deficiency leads to androgen excess, consequently, to virilization and rapid somatic growth with accelerated skeletal maturation. Mutations in CYP21A2 are responsible for different forms of 21-hydroxylase defi...

Objectives: Diazoxide is first line treatment for hypoglycaemia due to hyperinsulinaemic hypoglycaemia (HH). However, the FDA has raised serious concerns regarding diazoxide-induced pulmonary hypertension (PH) in 2015. Although sporadic cases of PH have been reported, no HH cohort has been systematically characterised to understand severity and risk factors for diazoxide-induced PH.Methods: To investigate the onset, progress and associated factors in PH,...

Background: Central hypothyroidism (CeH) is a rare thyroid hormone deficiency due to an insufficient stimulation of a normal thyroid gland. Candidate genes for isolated CeH include TSHβ, TRH receptor (TRHR) or IGSF1 genes while the combined pituitary hormone deficits (CPHDs) are the consequence of defects in embryonic pituitary transcription factors or in the prokineticin receptor 2 (PROKR2).Patients series: Here we report nine males (M) and 15 fema...

Innervation of the hypothalamic median eminence by Gonadotropin-Releasing Hormone (GnRH) neurons is vital to ensure puberty onset and successful reproduction. However, the molecular and cellular mechanisms underlying median eminence development and pubertal timing are incompletely understood. Here we show that Semaphorin-6A is strongly expressed by median eminence-resident oligodendrocytes positioned adjacent to GnRH neuron projections and fenestrated capillaries, and that Sem...

Background: Adenosine deaminase (ADA) deficiency is a systemic metabolic disease that primarily affects the immune system and lymphocyte development, causing a severe combined immunodeficiency (ADA-SCID). However, the accumulation of toxic metabolites occurs in other organs and systems. Since most ADA-SCID patients undergo definitive treatment with Gene Therapy (GT) or allogeneic haematopoietic stem cell transplantation (HSCT), preceded by conditioning (either...

Polycystic ovary syndrome is the most common cause of hirsutism and menstrual irregularity in adolescent girls and young women. It is often accompanied by obesity and insulin resistance and is associated to lifelong co-morbidities, including subfertility, type 2 diabetes, non-alcoholic fatty liver disease, pre-menopausal cancer, depression, low health-related Qol, and pregnancy and offspring complications. PCOS in adolescent girls is commonly driven by fat excess in subcutaneo...

Background and methods: Sellar and suprasellar tuberculomas are extremely rare in children and most often patients present with headache, vomiting, visual disturbances, and hypofunction of the pituitary gland. Here, we report a girl with hypothalamic obesity, that recovers after antituberculosis treatment.Findings: An 11-year old girl presented with headache, fever and anorexia that progressively evolved into an encephal...

Introduction: Hypoglycemia is a significant cause of morbidity in children, yet is challenging to diagnose and treat due to its heterogeneity.Aim: To describe the diagnoses and clinical characteristics of children with hypoglycemia referred to a tertiary pediatric center.Methods: This retrospective study included 155 children (86 males, aged 0-18 years) diagnosed with hypoglycemia ...

Introduction: GLIS3 is a member of the GLI-similar zinc finger protein family encoding for a nuclear protein that maps to chromosome 9p24.3-p23. Mutations in GLIS3 have been reported in association with Neonatal diabetes mellitus and hypothyroidism syndrome. We aimed to present a case of congenital diabetes mellitus congenital hypothyroidism associated with a newly identified mutation in the GLIS-3 gene.Case Report: A se...
