Background: Little is known about the long-term social outcome of diabetic children.Objective and hypotheses: This study aimed to describe social and professional life, quality of life (QOL) and sexuality at adult age of children and adolescents with type 1 diabetes (T1D).Method: Participants (n=388, age=28.5±3.1 years; duration of diabetes=17.0±2.7 years, recruited from a French national register) completed a qu...

Objective: To assess the characteristics of thyroid nodules among infants diagnosed with congenital hypothyroidism and to discuss the interest of a systematic screening.Material and method: A retrospective study of children with congenital hypothyroidism due to dyshormonogenesis was carried out at the pediatric endocrine center in Kremlin Bicêtre hospital, Paris, between 1999 to 2020. A screening ultrasound for thyroid nodules was t...

Context: Newborns with Congenital hypogonadotropic hypogonadism (CHH) have an impaired postnatal activation of the gonadotropic axis. Substitutive therapy with recombinant gonadotropins can be proposed to mimic physiological male mini-puberty during the first months of life.Objective: To retrospectively compare the clinical (penile size, volume and testicular descent) and biological efficacy (serum concentrations of test...

Background: Few studies have investigated in detail how the pubertal breast maturation in girls is related to the pubertal growth spurt in a longitudinal setting. The golden standard for assessment of secondary sex characteristics for girls includes breast development (B1-B5)1. The different maturation stages follow the increasing estradiol production from the ovaries also giving rise to the pubertal growth spurt. The QEPS-growth model makes it poss...

Background: Micronodular bilateral adrenal hyperplasia (MiBAH) is a rare cause of adrenal Cushing syndrome (CS) that may be subdivided in two main entities: primary pigmented nodular adrenocortical disease (PPNAD) and isolated micronodular adrenocortical disease (i-MAD). The most common presentation of MiBAH is familial PPNAD as part of Carney complex (CNC). The underlying genetic defect in most forms of PPNAD is inactivating germline mutations of the PRKAR1A ...

Summary: Severe obesity with various complications is a growing public health problem in childhood. Due to the lack of available hygienic and dietary therapeutic solutions, bariatric surgery has become, in recent years, one of the only effective treatments for severe obesity to induce persistant weight loss and reduce complications.Material and method: We analyzed a cohort of 162 patients followed in the specialized obes...

Growth failure is the gateway to a myriad of childhood and adolescent diseases. In the majority of cases, growth retardation is said to be constitutional after a detailed diagnostic evaluation. In the literature, there is a high degree of heritability of height (> 80%), underlining the predominant role of genetic factors.Objective: To identify new causes of growth retardation in 61 patients with constitutional familial short stature b...

Introduction: Children with CAH need a supraphysiologic dose of hydrocortisone, from 12-20 mg/m2/day to suppress adrenal androgens. Patients with difficult-to-treat CAH typically present with a combination of CAH-related (hyperandrogenemia, advancedbone age and short stature, amenorrhea) and glucocorticoid overtreatment–related clinical symptoms. Continuous subcutaneous hydrocortisone infusion therapy (CSHI) administered via an insulin pump has been used...

Homozygous loss-of-function mutations of the calcium-sensing receptor gene (CaSR) are associated with neonatal severe hyperparathyroidism (NSHPT), a life-threatening condition with a challenging treatment approach.We report a 7-day-old-female infant who was admitted to our Pediatric Department due to poor sucking. On examination she was lethargic and hypotonic. Laboratory evaluation revealed extreme hypercalcemia of 23.54 mg/dL (N: 7.6–10.4...

Introduction: Neonatal severe hyperparathyroidism (NSHPT) is a life-threatening disease characterized by hypercalcemia and bone demineralization due to homozygous or compound heterozygous loss-of-function mutations in the calcium-sensing receptor (CaSR) gene. Most cases require emergency parathyroidectomy to be life-saving. Alternative treatments, such as pamidronate and cinacalcet, may be used until surgery is feasible. We present a case of severe hypercalcem...
