Adult reproductive function is affected by early life environments and experiences, pointing to a possible role for epigenetic modifications in directing an adaptive response. Using mouse and cellular models, we have been studying the mechanisms underlying the shorter reproductive lifespan experienced by Bangladeshi women who grew up in Bangladesh as opposed to the UK, a phenotype associated specifically with the greater immune challenges in Bangladeshi childhood and altered D...

Aim: The most common cause of persistent hypoglycemia and related brain damage in infancy is congenital hyperinsulinism (CHI), due to inappropriate secretion of insülin by pancreatic βcells. The most frequent and most serious mutations are activating mutations in ABBC8 or KCNJ11 genes. Genetic analyses, which might predict the type of lesion, performed in early period and 18f dopa pet scanning are very valuable for treatment choice and follow-up of the patients. In t...

Type 1 diabetes (T1D) is a chronic disease characterized by the autoimmune destruction of pancreatic β cells. This destruction is mediated by lymphocytes T helper and cytotoxic, and by the action of the pro-inflammatory cytokines IL1β, IFNγ and TNFa inside the islets of Langerhans. We propose a new approach to alleviate islet inflammation by targeting pro-inflammatory cytokine receptors. Our hypothesis is that the downregulation of inflammatory pathways ma...

Background and Aims: Despite intensive insulin treatment of type 1 diabetes (T1DM), metabolic control remains suboptimal, especially in children. In an attempt to optimize postprandial glycaemia, some families decrease the amount of carbohydrates contained in a meal. While "low-carbohydrate diets" may improve metabolic control in some selected populations, controversies remain around the risk of hypoglycemia and ketoacidosis and the impact of such diet...

Introduction: Monogenic diabetes (MD) accounts for at least 3% of all pediatric diabetes cases. MD is often misdiagnosed as type 1 or type 2 diabetes, because of its wide phenotypic spectrum. While clinical and biochemical parameters can suggest MD, a definitive diagnosis requires genetic analysis. We conducted a broad study to diagnose MD cases. Then, with the gained knowledge, we designed a new diagnostic to...

Background: op’DDD can be used in adrenal cortical carcinoma (ACC) i) when surgery is impossible ii) or as an adjunct to surgery when local extension or metastases are present.Objectives and hypotheses: To report the unexpected spectacular effects of op’DDD in an unoperable ACC.Patient and results: A 3-year-old black African girl presented in poor shape with a 2-year history of pubic hair, clitoromegaly, abdominal distens...

Background: Reports of Cushing syndrome during the first month of life are rare. Mortality is high, despite medical (metyrapone) or surgical (adrenalectomy) treatment.Objectives: To report a new neonatal case of Cushing due to McCuneAlbright syndrome (MAS).Patient and results: Although a healthy baby at age 10 days, a newborn girl presented with sudden manifestations within the following 2 weeks: facial and truncal plethora, severe...

Context: Cryptorchidism, a common consequence of HH, is treated with orchiopexy. We previously observed that continuous subcutaneous infusion of gonadotropins restored normal serum testosterone and inhibin B concentrations in two infants with hypogonadotropic hypogonadism (HH) and was associated with testicular descent in one.Objective: Test if subcutaneous gonadotropin infusion within the first year of life can allow testicular descent in eight boys wit...

Background: Young adult patients with childhood-onset GH deficiency (GHD) whose GH replacement therapy (GHRT) is discontinued exhibit negative metabolic and physiological effects, reversible through GHRT.Objective and hypotheses: To report the characteristics and 5-year GHRT in adults with childhood-onset GHD.Method: Analysis of the subgroup of adults with childhood-onset GHD included between March 2003 and October 2006 in KIMS. In...

Background: Congenital hypothyroidism (CH) is the most common endocrine disorder in neonates and is predominantly caused by developmental abnormalities known as thyroid dysgenesis (TD). Several transcription factors have been described in its aetiology, but defects in the known genes only account for a small proportion of cases.Methods: To identify novel genes involved in TD, we performed exome sequencing in 7 unrelated ...
