Background: Pituitary stalk interruption syndrome (PSIS) is a frequent cause of congenital hypopituitarism. Patients are initially referred for the evaluation of hypoglycemia during the neonatal period or growth retardation during infancy or childhood. PSIS are either associated with extra-pituitary malformations (EPM+) or isolated (EPM−).Objective and hypotheses: To compare baseline characteristics, GH response, and long term evolution in patients...

Background: Hypercortisolism due to PPNAD may be cyclical, atypical and may develop suddenly or progressively.Objective and Hypotheses: The performance of salivary cortisol (SF) in this rare cause of Cushing’s syndrome (CS) is lacking.Method: Ten patients (nine F/one M) with PPNAD (two sporadic; eight Carney complex) were evaluated. Among these, six had CS family history, while in two the diagnosis was confirmed by germline PR...

Background: Osteogenesis imperfecta (OI) is a genetic connective tissue disorder with variable phenotype, mainly characterized by bone fragility, short stature and non-skeleton findings. Since growth failure is a predominant feature of OI, recombinant human growth hormone (rhGH) has been suggested as a potential intervention. We describe two boys with OI type I treated with rhGH.Case Reports: Patient 1 had the first frac...

Introduction: Achondroplasia is caused by a pathogenic mutation in the FGFR3 gene, leading to impaired endochondral bone growth and multiple medical complications. Vosoritide (once daily, subcutaneous injection) has recently been approved by the European Medicines Agency (EMA) for treating achondroplasia in patients aged ≥2 years until closure of epiphyses. It has been made available in France via an early access program, a cohort Temporary Authorization fo...

Background: In our bone unit, we were following since their younger age, two brothers with a severe osteogenesis imperfecta. We had no genetic confirmation but the severity of the disease combined with unaffected consanguine parents argues for a recessive autosomal transmission. Both present with highly severe form of osteogenesis imperfecta: repeated vertebral and peripheral fractures, long bone deformations, centromedullary nails on the lower limbs, major motor handicap and ...

Introduction: Achondroplasia is the most common skeletal dysplasia, in which the main clinical feature is short stature. Vosoritide, the first specific treatment for achondroplasia; administered as a daily subcutaneous injection, was approved by the European Medicines Agency in August 2021 for patients aged ≥2 years until closure of epiphyses. French Health Authorities granted early access to vosoritide treatment in France on 24 June 2021, which continued u...

Background: Cardiometabolic (CM) risk is linked to being small for gestational age (SGA, birthweight <-2SDS). Fetal growth restriction (FGR) may not result in SGA. We focused on potential CM risk in children born following pregnancies at higher risk for FGR.Aims: To identify associations between fetal and childhood weight trajectory quartiles and CM risk markers. 2.To define molecular pathways potentially associated w...

Introduction: Thyroid surgery in children is associated with high risk of recurrent laryngeal nerves (RLN) damage. It is due to complex and variable anatomy, high bleeding which decreasing visualization and requiring instrumental hemostasis. Large goiters change of syntopy, metastatic process requires bigger aggression and volume of intervention. The risk of damage significantly increases during repeated operations due to the scar process. There is significant...

Background: Hypospadias is a common characteristic of Disorders of Sex Development (DSD). At the present time a molecular diagnosis is not reached in over 50% of cases. The DDD Study represents a useful resource of large molecular and phenotypic datasets obtained from individuals with an undiagnosed developmental abnormality including DSD.Objective: To review associated features and identify likely pathogenic variants in previously undiagnosed DDD partic...

Background: Collaborative project to review the phenotypic and genotypic data from children recruited to the UK wide deciphering developmental disorders (DDD) study.Objective and hypotheses: To report the frequency and range of disorders of sex development (DSD) phenotypes observed in DDD participants who have one or more associated ‘neurodevelopmental delay’ diagnostic human phenotype ontology (HPO) term.Method: Retrospe...
