Background: Leprechaunism, due to a mutation of both alleles of insulin receptor gene, is a most severe and precociously life-threatening condition, difficult to treat.Objective and hypotheses: In leprechaunism rhIGF1 may replace insulin through I the insulin-like metabolic properties of its own receptor.Method: rh IGF1 was continuously subcutaneously administered through a.pump from the age of four months and adjusted according to...

Background: Nearly 10% of paediatric onset diabetes are auto-antibodies negative. Among them monogenic diabetes are frequently under-diagnosed. The major increase in the prevalence of childhood obesity is misleading with a risk of confusion between type 2 diabetes (T2D) and monogenic causes of diabetes.Objective and hypotheses: To report on two informative families with negative auto-antibodies childhood-onset diabetes cases.Method...

Background: More than 20 gene loci are known to cause monogenic neonatal diabetes today. A definite mutation can be found in 65–70% of all cases. Mutations in the ATP sensitive potassium channel can frequently be treated by sulfonylurea. Glibenclamide is on of the drugs known to inhibit the bile salt export pump (BSEP). However most drug induced cholestasis cases are reported in adults.Objective and hypotheses: Glibenclamide is used frequently to tr...

Background: There are international guidelines on screening for Microalbuminuria (MA) in children with Type1 Diabetes Mellitus (T1DM). But the National Paediatric Diabetic Audit, UK suggests that screening is missed in over 50% of cases. Further, there is little data on the management and natural course of MA in children by frontline units.Objective and hypotheses: To describe the prevalence, management and natural course of MA in children and adolescent...

Background: Cataract as a chronic complication of diabetes is well established in the literature and the risk factors are also well known. However, rare cases of acute bilateral cataract have been reported, all of them happening relatively shortly after diagnosis in T1DM. While the pathophysiology of this phenomenon remains unclear – as a lot of different theories proposed so far with the most accepted being the osmotic stress induced oxidative damage – fail to expla...

Background: Vaginal agenesis (VA) in MRKH syndrome can be managed either by surgery or autodilatations.Objective and hypotheses: To compare different managements of MRKH-VA in terms of quality of life, sexual function, anatomical results and complications.Method: National Multicentric observationnal study including 130 patients older than 18, at least one year after completing VA management, from October 2012 to April 2015. 84 had ...

Background: Steroidogenic factor-1 (SF-1), denominated as nuclear receptor subfamily five group A member 1 (NR5A1), is an orphan receptor that regulates several steps of adrenal and gonadal development. Mutations in its gene are responsible for different phenotypes of disorders of sex development (DSD).Objective and hypotheses: To study the functional impact of two novel NR5A1 mutations, the p.C247* and p.K396Rfs*34, both identified within the l...

Background: Current guidelines recommend that gender dysphoric adolescents be treated with puberty suppression using gonadotropin releasing hormone analogues (GnRHa) followed by cross sex hormones. However limited data are available on the safety and side effects of this treatment. In adults changes in adrenal steroids have been observed during cross sex hormone treatment.Objective and hypotheses: We aimed to investigate the effect of GnRHa and cross sex...

Background: Patients with 45,X/46,XY mixed gonadal dysgenesis (MGD) have variable phenotypes leading to both male and female sex assignments. A multidisciplinary team should guide the process of sex assignment, however a standardized approach may provide objective guidance for the team as well as a tool for settings without such resources. One of the most important considerations for sex assignment is the hormonal production, which often determines the degree of virilization. ...

Background: Polycystic ovary syndrome (PCOS) is a complex endocrine genetic disorder, which is associated with increased metabolic and cardiovascular morbidity. Vitamin D or omega-3 fatty acids supplementation may alleviate the metabolic and reproductive complications of PCOS.Objective and hypotheses: To compare clinical, psychometric, biochemical, endocrine, bone and sonographic markers in vitamin D sufficient adolescents with PCOS, pre- and post- 6 mon...
