Background: Partial androgen insensitivity syndromes (PAIS) are rare 46,XY DSD (disorder of sex development).Objective and hypotheses: Three families with PAIS (six patients) are reported, focusing on their phenotype and treatment depending on sex of rearing. Biological investigations and surgical management are described.Method: Between 2009 and 2015 a consultation for uro-genital malformations in pediatric patients was set up in ...

Background: Maternal bariatric surgery is associated with increased risk of small-for-gestational-age infants. Risk of nutritional deficiencies in neonates of mothers with prior gastric bypass (GBP) is unclear.Methods: This study compared the clinical and cord blood biological characteristics of 56 newborns of GBP mothers and 56 newborns of healthy mothers, in the Obstetrics Department of Angers University Hospital between 01/03/2008 and 31/10/2012. Afte...

Introduction: HbA1C goals are rarely achieved in children with Type 1 diabetes (T1D) except at the cost of increased hypoglycaemia episodes. The Diabeloop Hybrid Closed-Loop system improves time in range and glycemic control in adults. However, the efficacy and safety of the system had not yet been evaluated in children. Our objective was to evaluate the safety and efficiency of the Diabeloop hybrid closed-loop system in prepubescent children (DBL4K).<p cl...

Background: Children and young people living with severe obesity experience a range of complications of excess weight (CEW), however the prevalence of complications is not well defined. We have evaluated baseline clinical characteristics and CEW of patients seen in two multi-disciplinary tier-3 paediatric weight management services in different regions of the UK.Methods: All new patients (n=185) aged 2-17 years ...

Background: The SCOPE French retrospective study follows children affected with growth hormone (GH) disorders treated with recombinant human GH (r-hGH) therapy via the easypod® connected injection device for up to 5 years.Aim: To show the results from an interim analysis of the SCOPE study analysing adherence to r-hGH therapy in a real-world setting and its effect on catch-up growth.Met...

DSD-LIFE is a comprehensive clinical outcome study investigating medical, surgical, psychosocial, and ethical issues to improve treatment and care of patients with the different diagnoses included in the umbrella term disorders/differences of sex development (DSD). The multidisciplinary DSD-LIFE consortium consists of 15 experienced European scientists in the areas endocrinology, psychology, surgery, gynaecology, urology, and ethics. In 2013 the study protocol and the online d...

Background: Phosphoglucomutase 1 (PGM-1) deficiency is a congenital disorder of glycosylation caused by an impairment of glucose-1-phosphate and glucose-6-phosphate interconversion.The clinical phenotype of PGM1 deficiency is variable and includes several endocrine manifestations such as recurrent hypoglycemia and short stature, which may be associated with the decreased levels of growth hormone (GH), insulin like growth factor-1 (IGF1) ...

Background: Steroidogenic Factor 1 (SF-1), encoded by NR5A1 (Nuclear receptor subfamily 5 group A member 1) gene, is a transcriptional factor that is primordial for adrenal and gonadal organogenesis. Pathogenic variants of NR5A1 are responsible for a wide spectrum of phenotypes with autosomal dominant inheritance, from adrenal insufficiency to gonadal dysgenesis and oligospermia-azoospermia in 46,XY patients.Obj...

Introduction: Congenital Lipoid Adrenal Hyperplasia (CLAH) is a severe deficiency of adrenal and gonadal steroidogenesis, caused by mutations in the StAR gene and the accumulation of cholesterol in the outer mitochondrial membrane due to steroidogenic acute regulatory protein (StAR) deficiency. Affected patients present peripheral adrenal insufficiency with early onset, and variable phenotypes at the age of puberty.Objective of o...

Background: Pure gonadal dysgenesis 46 XY is a rare form of sexual differentiation disorders.Objective and hypotheses: This study describes the diagnosis circumstances, clinical, biological and radiological presentation, and genetic aetiology of 14 patients with a 46 XY pure gonadal dysgenesis.Method: It is a retrospective descriptive multicenter study from Necker Hospital (Paris) and Lille university hospitals.<p class="abstex...
