Background: 21-Hydroxylase deficiency due to mutations in CYP21A2 represents the commonest form of congenital adrenal hyperplasia (CAH). Dyshormonogenetic congenital hypothyroidism (CH) may be due to TPO, TG, DUOX2, DUOXA2, IYD, SLC5A5 and SLC26A4 mutations.Objective and hypotheses: We report a kindred with three siblings born to unrelated parents manifesting with two different forms...

Background: Diabetes insipidus (DI) is characterised clinically by the inappropriate production of large volumes of dilute urine even in the presence of clinical dehydration or deprivation of water. DI occurs either due to a deficiency or insufficiency of arginine vasopressin (AVP) hormone production. Hereditary DI accounts for <10% of the DI cases. As hyponatraemic seizures secondary to inappropriate use of desmopressin can occur, caution is required before a diagnosis of...

Background: Sulfonylurea therapy allows a better metabolic control than insulin in patients with neonatal diabetes secondary to mutation in potassium channel. Its galenic form (tablets) is not suitable for children, as the dosage can’t be easily modulated and as it induces large pharmacokinetics (PK) variations when administer to young children.Objective and hypotheses: To measure relative biodisponibility of a new galenic form of glibenclamide and ...

Background: Growth charts constitute an important tool to monitor a child’s growth and development, and thus detect growth anomalies. Growth assessment allows early referral and management of treatable disorders. In France, the currently used growth reference charts were derived at the end of 1970s, based on children born on 1950s in Paris area. Questions are raised about their use for growth monitoring of more recently born children.Objectives: To ...

Background: Secondary pseudohypoaldosteronism presents with hyponatremia and hyperkalemia due to a transient aldosterone resistance.Objective and hypotheses: We recommend a check of urea and electrolytes in all infants with urinary tract infection, dehydration and failure to thrive.Method: A 5 month old presented with a day’s history of poor feeding and two episodes of vomiting. He was afebrile with normal observations. His ur...

Background: Neonatal diabetes can present from birth to six months of age. This can often be confused with sepsis as there is considerable overlap of symptoms in this age group as illustrated below.Objective and hypotheses: The cases described illustrate the importance of blood glucose monitoring in sick infants presenting to emergency care settings we recommend an initial check of blood glucose concentrations in all sick infants who present to Accident ...

Background: Paediatric diabetes has been the focus of attention during the COVID-19 pandemic. There are reports of increased incidence of new-onset type 1 paediatric diabetes and concerns about delayed presentations to the Emergency Department (ED) due to parental fears of SARS-CoV-2, resulting in an increase in the incidence and severity of DKA in children with new-onset diabetes.Objectives: To characterise the features...

Introduction: The COVID-19 pandemic led to regional lockdowns and restrictions associated with changes in lifestyle and quality of life (QoL) thus potentially burdening metabolic control in Diabetes Mellitus (DM). We examined whether the stages of restrictions lead to changes in QoL and metabolic control in children with DM.Methods: Starting in April 2020, this monocentric prospective longitudinal cohort study included c...

Background: In 2013, Abreu et al identified loss-of function mutation in the MKRN3 gene of fifteen patients from five families with idiopathic central precocious puberty (iCPP), highlighting the implication of this maternally imprinted gene in this still poorly understood condition. Since this study, other mutations have been described and now represent the most common genetic cause of iCPP.Objective: The objective of th...

Congenital Hyperinsulinism (CHI) is primarily associated with defects in the regulated release of insulin from ß-cells but little information is available about the role of other islet cell types. Pancreatic polypeptide (PP) cells represent a minor component of the islet endocrine cell population. PP causes satiety, decreases gastrointestinal tract motility and suppresses glucagon release. Since CHI is associated with feeding problems and loss of glucagon-mediated counter...
