Background: 46,XY patients with SF-1 mutations have sex reversal or ambiguous genitalia (with or adrenal insufficiency) due to dysgenetic testis. In most cases, a severe defect in testosterone (T) production has been found. We described here 3 cases showing the variability in T production.Results: Case 1: A was seen at the age of 17 years for primary amenorrhea. Tanner stage was B2PH3. External genitalia were normal. FSH was 55 IU/l, LH 17 IU/l,...

Background: Congenital hyperinsulinism (HI) is the most common cause of persistent hypoglycemia in infants and children.Objective and hypotheses: Recently, mutations in genes usually involved in MODY 1 and 3 have been described in HI.Method: We present here six cases of hyperinsulinism associated with MODY1 (one case) and MODY3 (four cases) and one case of HI associated with MODY5 mutation.Results: Case 1...

Background: Congenital isolated adrenocorticotrophic hormone (ACTH) deficiency (IAD) is a rare condition. It is characterized by low plasma and cortisol levels and preservation of all other pituitary hormones (2 cases described with transient partial growth hormone deficiency). The principal molecular cause is identified as TPIT mutation. We present here the case of a neonate with TPIT mutation and ACTH deficiency associated with probable growth hormone and thyrotropin deficie...

The mineralisation measured by DXA, bone-mineral-content (BMC), of obese boys seems to be better than that of lean boys and It is known that obese children are taller than healthy children. Is this the only factor that explains the better DXA measurements of obese boys? And how explain the fact that these boys have more fractures of the extremities? We described bone mineralization in boys with overweight/obesity and leanness in relation to body composition. Cross-sectional st...

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...

Background: Wiedemann Steinert Syndrome (WSS) is characterized by distinctive facial features (hypertelorism, thick eyebrows, long philtrum, broad nasal bridge), growth retardation, and intellectual disability of varying degrees. Affected individuals are often born small for their gestational age and have generalized hypertrichosis. Some have growth hormone deficiency, usually partial with normal pituitary MRI. The disease is caused by autosomal dominant varia...

Background: Neonatal hyperinsulinism is the most frequent cause of neonatal recurrent hypoglycaemia. The persistent form can be explained by mutations of genes involved in beta cell function, whereas the transient form can occur in case of prematurity, low birth weight, macrosomia, perinatal hypoxia, and maternal diabetes.Objective and hypotheses: As we observed an increase in the incidence of neonatal hyperinsulinism, we hypothesized that potential mate...

Context: Alterations in semen characteristics and Sertoli and Leydig cell function have been described in obese male adults. Whether these alterations occur before adulthood has not been fully evaluated.Objective and Design: Cross sectional study from 2010 to 2018 describing gonadic function in overweight-obese (ow/ob) boys through childhood and adolescence.Setting: Monocentric study in the Pediatric Endocrinology ...

Introduction: In obese boys, alteration of Sertoli and Leydig cell functions have been described, but potential reversibility of these alterations after weight loss during childhood has not been fully evaluated.Objective: Evaluate the impact of weight loss on gonadic function in obese boys.Setting: Monocentric study in the Pediatric Endocrinology Unit of Angers University Hospital ant its follow-up...
