Introduction: Differences of sex development (DSD) encompass a variety of conditions with atypical development of chromosomal, gonadal or anatomic sex. 46, XX ovotesticular (OT) DSD is a rare condition, in which the presence of testicular and ovarian tissues is identified in the same individual. These patients present variable phenotypes with a wide spectrum of atypical genitalia and their sex assignment can be male or female. Short stature is a frequent issue...

Abstract: Congenital hyperinsulinism (CH) is the most frequent cause of persistent hypoglycemia in the newborn. Octreotide, a long-acting somatostatin analogue (SSA), is a second line treatment for diazoxide unresponsive CH patients. Although it has been found to be a safe and effective treatment, long-term benefits and side effects have not been thoroughly evaluated. Furthermore, some authors have emphasized that exocrine pancreatic insufficiency is a common ...

Background: Autoimmune diseases (AIDs) have familial aggregation and frequently share a common genetic background, but few studies have evaluated autoimmune clusters in children with AIDs and their families.Objective and hypotheses: To identify clusters of AIDs in children and their first-degree relatives.Method: A cross-sectional study was performed in subjects with an AID of pediatric onset (<18 years) recruited at Pediatric ...

Background: Hypothalamic obesity (HyOb) is a disease characterized by weight gain resistant to lifestyle changes and dietary restriction. The main clinical findings are hyperfagia and decline of satiety, high levels of insulin and an increase of adipogenesis. The major problem for these patients is that conventional treatments, either medical or surgical are not succesful and have variable results.Objective and hypotheses: We aim to describe the natural ...

Background: French health authorities have developed a national program to organize outpatient care networks for the prevention and management of obesity in children and adolescents (Réseau de Prise en Charge de l’Obésité Pédiatrique (REPOP)). To date, REPOP Ile-de-France has more than 250 primary care physicians with dietitians, nurses, educators, and psychologists trained in the management of childhood obesity as part of a standard care pathway, work...

Introduction: Improvements in the treatment of acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL) have increased survival, with the consequent concern about the long-term effects that childhood chemotherapy may have on ovarian function. AMH constitutes an indirect, reliable biomarker of the ovarian reserve, useful for the assessment of cancer therapy-related ovarian damage.Aim: To evaluate small ovarian f...

Introduction: Non-communicable diseases are recognized as a major cause of morbidity in low and middle-income countries (LMICs). There are 21 francophone countries (>100 million speak French) in Sub-Saharan Africa (FSSA). We identified only 19 pediatric endocrinologists in FSSA (37% in Cameroon and Senegal) mostly trained in France or through the successful anglophone “Paediatric Endocrine Training Centers for (West) Africa” (PETC[W]A) offered i...

Context: Congenital hypothyroidism from thyroid dysgenesis (CHTD) is mainly a sporadic and non-syndromic condition occurring in 1:4,000 live births. In contrast to rare cases of syndromic monogenic CHTD, non-syndromic (NS) CHTD shows low familial recurrence risk (~2%) and low concordance rate between MZ twins, suggesting a two-hit scenario combining post-zygotic events with either a de novo monogenic mutation or incomplete penetrance of polyg...

Triple A syndrome (AAAS) is a rare, incurable, recessive disorder, characterised by achalasia, alacrima, adrenal failure and a neurodegenerative phenotype. The AAAS gene encodes ALADIN, is a nuclear pore complex (NPC) protein necessary for nuclear import of DNA protective molecules, important for redox homeostasis. ALADIN’s role is not fully characterised: its discovery at the centrosome and the endoplasmic reticulum suggests a role outside the NPC. To date, the ...

Introduction: Various types of mutations in GHRHR cause isolated growth hormone deficiency type 1B. Here, we report the clinical features associated with deletion of whole GHRHR gene for the first time.Case: A four-year–and-nine-month-old otherwise healthy girl was admitted due to short stature. She was born at term with a birthweight of 3750 gr. Her height velocity slowed down after 2 years of age. The mother (157.8 cm, −0.8...
