Context: Newborns with Congenital hypogonadotropic hypogonadism (CHH) have an impaired postnatal activation of the gonadotropic axis. Substitutive therapy with recombinant gonadotropins can be proposed to mimic physiological male mini-puberty during the first months of life.Objective: To retrospectively compare the clinical (penile size, volume and testicular descent) and biological efficacy (serum concentrations of test...

Methods: Patients commenced 0.75mg/kg carbimazole (CBZ) daily with randomisation to either BR or DT. We examined baseline patient characteristics, CBZ dose, time to serum TSH/FT4 normalisation and BMI Z-score. Results: There were data available from 80 patients (baseline) and 78 patients (61 female) at 6 months. Mean CBZ dose was 0.9 mg/kg/day (BR) and 0.5 mg/kg/day (DT). There was no difference in the time taken for...

Short stature and hypogonadism are frequent symptoms in Turner syndrome (TS). In most cases, puberty must be induced but pubertal induction modalities are not consensual. Moreover, pubertal induction impact on final height and pubertal growth spurt has not been studied in depth. Our aim was to study factors influencing final height during pubertal induction in TS. Retrospective cohort of 45 TS girls followed in a single center: Bicetre hospital. We recorded auxological paramet...

Background/aim: Hyperparathyroidism (HPHT) is a common feature in patients with X-linked hypophosphatemia (XLH) especially when treated with vitamin D analogues and phosphate supplements. Although the exact mechanism is not clear, it is assumed that phosphate supplements taken chronically stimulate parathyroid hormone (PTH) secretion. We prospectively assessed the effect of a novel pathogenetic treatment anti-FGF23 (burosumab) on PTH levels in children with XL...

A new condition, unique to Irish Travellers, was first described clinically as autosomal recessive natural killer and glucocorticoid deficiency (AR-NKGCD) ORPHA:75391 in 2008 and was attributed to recessive founder variant in MCM4/PRKDC gene in 2012. Irish Travellers are an indigenous endogamous population numbering ~40,000 in the Republic of Ireland. AR-NKGCD is characterised by short stature, glucocorticoid and natural killer cell deficiency and is a disorder of DNA repair. ...

Background: Glibenclamide has proven to be efficient for patients with neonatal diabetes owing to potassium channel mutations. Anyway its pharmaceutical form is not suitable for young children or infants. The tablets dosage is too high for most infants and must be crushed and diluted before administration. We developed a suspension of glibenclamide (EMA Orphean drug designation january 2016) fitting recommendations of drug administration to allow a precise dosage and designed ...

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...

Background: A meta-analysis of 39 studies using multicomponent lifestyle interventions, in comparison to standard, minimal, or no treatment identified a mean difference in BMI z-score of -0.12 (95% CI -0.17 to -0.06) at six months. However, a minimum BMI-SDS reduction of 0.25 or greater has been shown to improve metabolic health in overweight children. We describe our experience in a multidisciplinary (MDT) clinic at a tertiary children's hospital with...

Background: Interplay of various factors contribute to development of morbid childhood obesity and to its recalcitrant nature making it a treatment challenge. A tertiary level, structured multidisciplinary outpatient approach may not always be sufficient in identifying morbid obesity causation. In the absence of other effective treatment modalities, a hospital stay approach can be a suitable option in selected resistant cases.Met...

Background: Pseudohypoparathyroidism type 1A (PHP1A) and PseudoPHP are caused respectively by maternal and paternal mutations involving those GNAS exons that encode the alpha-subunit of the stimulatory G protein (Gsα). Common to different forms of PHP1B is a loss-of-methylation (LOM) at one or several maternal GNAS exons, which likely reduces Gsα expression in certain tissues. In most autosomal dominant PHP1B variants (AD-PHP1B), LOM is restricted t...
