Background: The surgical reconstruction of hypospadias is usually performed during the first 2 years of life but little objective data is available to determine its optimal timing. Whereas the no-early surgery option in DSD management is rising, the results of late genital surgery should be evaluated before advocating this attitude.Objective and hypotheses: To evaluate the outcome of hypospadias surgery according to age and to determine if some complicat...

Adeno-associated virus (AAV) gene therapy reached the maturity and a liver-targeting approach is currently used as a replacement treatment for rare hepatic and muscular diseases. X-linked hypophosphatemia (XLH) is a rare disease associated with hyperfunction of fibroblast growth factor 23 (FGF23) in bone and characterized by severe skeletal deformities and short stature. The current medical therapies for XLH requires life-long repeated treatment presenting major limitatio...

Introduction: In adolescents and men with PAIS, gynaecomastia has been reported in the majority but its management remains challenging.Objectives: To assess the current management of gynaecomastia as well as clinical characteristics in male PAIS.Materials and Methods: Retrospective review in the I-DSD registry of 46, XY male PAIS who were over the age of 10 years.<p class="abst...

Background: Partial Androgen insensitivity syndrome (PAIS) is a rare condition which is associated with a variable phenotype. To date, there are limited data reporting long-term endocrine outcome for this condition.Aims: To determine the outcomes and clinical characteristics for 46, XY males with PAIS, using information from the International DSD (I-DSD) Registry and its clinical users.Methods: The I-DSD Registry and its users were...

Background: It is well known that boys are heavier than girls at birth. Causes of this difference are thought to originate from the Y chromosome and as a result of androgen action. Although some studies showed that sex dimorphism in size at birth is dependent of fetal androgens, one study reported that it is not generated by action of androgens.Objective and hypotheses: To determine birth weight (BW) of children in different aetiologies of disorder of se...

Objective: Craniopharyngioma is a benign brain tumour with frequent local recurrence after treatment. Growth hormone replacement therapy (GHRT) is prescribed in children with growth hormone deficiency due to childhood-onset craniopharyngioma. The objective was to evaluate whether shorter time delay of GHRT initiation after childhood-onset craniopharyngioma completion therapy increased the risk of recurrence.Design: Our r...

Background: Klinefelter syndrome (KS) is associated with an increased risk of lower socioeconomic status and a higher risk for morbidity and mortality, which may have a significant impact on quality of life (QOL). The objective of this study is to investigate QOL in a large European cohort of men with KS and associate QOL with socioeconomic status, prevalence of somatic disease and mental illness, testosterone supplementation and age of diagnosis.<p class=...

Background: Twenty-three national healthcare networks for rare diseases were identified in 2014 as part of the French scheme on rare diseases. The rare endocrine disease national healthcare network FIRENDO (www.firendo.fr) includes six centers of reference with complementary fields of expertise certified between 2005 and 2006, 30 centers of competence covering all French regions, 18 research and 37 diagnostic laboratories, 5 national learned...

Background: Transient neonatal diabetes mellitus (TNDM) is a rare genetic β-cell dysfunction leading to hyperglycaemia that resolves in early childhood. About 80% of patients relapse during adolescence or adulthood. Some of these patients suffer from neurodevelopmental defect. Long-term outcome has been poorly investigated.Objective and Hypotheses: To investigate metabolic and neurologic outcomes in adults affected with TNDM.M...

Introduction: Ghrelin binds to its receptor GHSR1A, encoded by GHSR, on somatotrophs of the pituitary. Growth hormone (GH) secretion is enhanced by ghrelin binding as well as the receptor’s constitutive activity. Results from in vitro experiments, knock-out mice, and GWAS suggest that heterozygous loss-of-function of GHSR may be associated with short stature, but observations in case studies are equivocal. We aimed to better ch...
