Background: Leptin is produced by adipocytes and regulates central hunger and satiety sensation. While the central leptin effects are well understood, little is known about the regulation of peripheral leptin production. Clinical data demonstrate that leptin levels are rapidly declining upon fasting, suggesting that leptin secretion is acutely regulated by nutrient availability. Although it has been previously shown that leptin secretion is under control by gl...

Background: 11-oxygenated 19-carbon (11oxC19) steroids, 11ketotestosterone (11KT) and 11βhydroxyandrostenedione(11OHA4) are adrenally derived steroids that rise in congenital adrenal hyperplasia (CAH). Increased 11oxC19 concentrations are associated with markers of poor control of CAH. To date, 11oxC19 concentrations have not been measured in patients with Addison’s disease (AD).Methods: Children with primary ...

Background: Concerns about a child's growth are one of the most common topics parents express during pediatric visits and are a leading cause for referral to a pediatric endocrinologist. For the general pediatric, when short stature is diagnosed, its clinical management remains a challenge.Objective: The aim of the study was to approach and understand the perception from the general pediatrician about short stature,...

Background: Septo-optic dysplasia (SOD) is a rare condition diagnosed in children with two or more of the following: hypopituitarism, midline brain abnormalities, and optic nerve hypoplasia (ONH). Children with SOD experience varied visual impairment and endocrine dysfunction. Autistic-like behaviours have been reported, however the nature and prevalence of these neurobehavioural impairments remain to be fully understood. The present systematic review aimed to...

Central diabetes insipidus (CDI) at neonatal age may occur in the setting of intracranial abnormalities that affect the hypothalamus-pituitary system. These conditions are characterized by defective production, transport or secretion of antidiuretic hormone (ADH). This results in inappropriately low ADH levels in the setting of increased plasma osmolality. We present the case of an infant born by C-section at 38 weeks of gestation, with bilateral cheilognatopalatoschisis, naso...

Hyperinsulinemic hypoglycemia (HH) is common in newborns. If hypoglycemia occurs after the first 48 hours following birth, it may be a sign of an underlying condition. We present the case of a baby girl born at 38 weeks of pregnancy, with good adaptation to extrauterine life and blood glucose of 60 mg/dl in the first days of birth. Approximately 2 days after discharge, she was addressed at the emergency unit because of food refusal for approximately 30 hours, with a blood suga...

Introduction: In youth, primary ovarian insufficiency (POI) is due to genetic, autoimmune, iatrogenic, and idiopathic etiologies. When POI is diagnosed early with evidence of an ovarian reserve, fertility preservation can be offered. When the girl is premenarchal, the preferred fertility preservation method is ovarian tissue cryopreservation (OTC) containing primordial follicles. In the past, when OTC was performed in an unselected group of children and adoles...

Recently, we identified Neuritin 1 (NRN1) as preferentially expressed in human white compared to brown adipocyte progenitor cells. In mice, Nrn1 deficiency leads to a reduction in body weight, indicating that it might regulate body weight. In this study, we aim to address the function of NRN1 regarding adipocyte metabolism in vitro and in vivo. We used human SGBS preadipocytes as an in vitro model system. NRN1-deficient cells were generated using len...

Background: The French population of the SAGhE study showed an increased morbidity and mortality due to cerebrovascular disease in growth hormone (GH) treated subjects compared to the general population. Cerebrovascular health can be assessed using neuroimaging markers on MRI. One of the markers is white matter hyperintensity (WMH).Objective: To assess cerebrovascular health by scoring WMH on MRI in young adults born sma...

Introduction: When used to treat obesity, glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1RA) improve both BMI and metabolic health. Liraglutide is approved by both the EMA and FDA for the treatment of pediatric obesity, from 12 years and older. However, 26 weeks after discontinuation of liraglutide, the weight lost during treatment is regained. Prolonged exogenous stimulation of hormone-specific receptors may influence endogenous hormonal regulation. ...
