Background: The familial non-autoimmune hyperthyroidism (FNAH) is a hereditary disease caused by dominant activating mutations of the TSH receptor (TSHR) gene and rare in the paediatric population.Case presentation: A 20-month girl was referred for tachycardia. In personal history, she was delivered at 35 weeks of gestation by caesarean for fœtal tachycardia; she had been hospitalised at 1 and 5 months for diarrhoea and tachycardia was noticed. Clin...

Background: Non functioning pituitary macro adenoma is rare during childhood. Therapeutic options are reduced to surgery and radiotherapy. Proton therapy is a particle therapy that uses a beam of protons to irradiate the tissue with the chief advantage that as a charged particle the dose is deposited over a narrow range and there is minimal exit dose.Objective and hypotheses: Proton therapy is largely used in France for paediatric craniopharyngiomas irra...

Background: Acquired Von Willebrand's syndrome (aVWS) associated with hypothyroidism is rare in children and more often diagnosed during the peripubertal period in the context of Hashimoto's thyroiditis.Case presentation: A 5-year-old girl was referred to the paediatric haematology unit for rectal bleeding, anaemia, and prolonged activated partial thromboplastin time. Her developmental and learning skills were no...

Benign breast diseases (BBD) have always been neglected in comparison to cancer, despite the fact that there are many more patients with such diseases than patients presenting to a breast clinic for cancer, especially in young women. So far, BBD have been the subject of a relatively few isolated and unconnected studies, and earlier related work has often been ignored. This situation has led to a great deal of confusion, especially because different authors have their own nomen...

Primary (premature) ovarian insufficiency (POI) is defined as a loss of ovarian activity before the age of 40, and is characterized by menstrual disturbances (amenorrhea or oligomenorrhea) with elevated gonadotropins (follicle-stimulating hormone [FSH] ≥ 25 IU/L) and low serum estradiol levels. The incidence of POI is around 1 per 100 women overall, and 1 per 1000 women under the age of 30 years. POI leads to infertility and an increased risk of osteoporosis and cardiova...

Patients with Turner syndrome (TS) have short stature, despite having normal growth hormone (GH) secretion. Treatment with recombinant human GH is recommended. The effectiveness and safety of Norditropin® (somatropin, Novo Nordisk) over ≤10 years of follow-up were investigated in two non-interventional studies: NordiNet® IOS (NCT00960128) and the ANSWER Program (NCT01009905). Of 2,409 children with TS, 2,377 were included in the full analysis s...

Aims: Recently, our team introduced the concept of post-hypoglycemic hyperglycemia (PHH) in the context that recovery of hypoglycemia impacts cardiovascular risk. GLUREDIA study aimed to evaluate whether PHH parameters correlated with glycemic homeostasis during the first year after type 1 diabetes onset and helped to distinguish pediatric patients undergoing partial remission or not.Methods: In the GLUREDIA study, longi...

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...

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...
