We recently showed that Xq26.3 microduplications are associated with early childhood-onset gigantism, a condition we named X-linked acrogigantism (X-LAG). Patients with X-LAG present with mixed GH/PRL secreting pituitary macroadenomas and/or hyperplasia. The original smallest region of overlap for the microduplications included 4 coding genes, of which only one, an orphan G protein-coupled receptor named GPR101, was highly expressed in tumors. A single patient with GP...

Background: Congenital diabetes insipidus (DI) can be due to mutations in the arginine vasopressin (AVP) gene (familial neurohypophyseal DI), the AVP receptor type 2 (AVPR2) or aquaporin 2 (AQP2) genes (congenital nephrogenic DI, NDI). The clinical manifestation of congenital NDI, especially the response to AVP, can vary greatly depending on the functional effect of the AVPR2 mutation. Here we present two male siblings with NDI and partial response to ddAVP.<p class="abste...

Background: Bone X-rays provide the main diagnostic parameters for chondrodysplasia, including common dyschondrosteosis (DC). Skeleton is usually studied piece by piece by visual analysis in search of characteristic signs. The phenotypic spectrum of DC is large. Indeed, children who have seemingly idiopathic short stature (ISS) may have subtle forms of DC that can be unrecognized.Objectives: Provide a user-friendly computer-assisted program that facilita...

Introduction: Gsα is imprinted in human thyroid glands and this appears to be important in the development of moderate TSH resistance in pseudohypoparathyroidism (PHP) 1A and less severe TSH resistance in some, but not all, other forms of PHP. Obesity is a clinical condition in which subclinical alterations of thyroid function have been reported, although the relationship between thyroid status and obesity remains unclear. It is uncertain if this biochemical abnormality m...

Background: Type 1 diabetes (T1D) in teenagers is challenging: the constraints of diabetes add up to the specificities of a delicate age; moreover, this period of life is often associated with impaired metabolic control (i.e. higher hemoglobin A1c - HbA1c). Therapeutic Patient Education (TPE) enables people with chronic diseases to manage their illness and yields benefits in both health and financial terms. The first step of TPE approach is to make an “educational diagnos...

Background: Carnitine deficiency (CD) has been reported in children at time of type 1 diabetes (T1D) diagnosis. By impairing free fatty acid ß-oxidation in liver, muscle mass and pancreatic ß cells, CD might impair glucose homeostasis and residual insulin secretion. We postulate that reversed of these FAO defects may help regenerate a healthier ß cell mass and increased the diabetes honeymoon duration.Objective: Evaluate the effects of car...

Background: Hematocolpos is a rare condition in young girls that can be caused by imperforated hymen or vaginal agenesis. It is usually diagnosed at early puberty with cyclic abdominal pain and amenorrhoea. Menarche is usually observed two years after the start of puberty; sometimes pre-menarcheal bleeding can occur, ranging from isolated premature menarche to spotting in course of puberty. In case of imperforated hymen or vaginal anomaly, a pre-menarcheal uterine bleeding can...

Background: Following years of dietary and lifestyle intervention (DLI) as the only therapeutic option, reports of bariatric surgery are emerging in adolescents with morbid obesity. We present herein preliminary results of our 4-yr sleeve gastrectomy study.Objectives and hypotheses: To compare the effects of laparoscopic sleeve gastrectomy (LSG) and intensive DLI in adolescents with morbid obesity (ie BMI >4 DS) and extremely active weight gain (i.e....

Background: Dietary and lifestyle modifications commonly proposed to overweight or obese youth lack efficacy in those with severe obesity. Early results with bariatric procedures in obese adolescents suggest that weight loss and safety are comparable or better than those seen in adults. One of these procedures, laparoscopic sleeve gastrectomy, is commonly performed using multiple ports. We selected single port sleeve gastrectomy (SPSG) as a minimally invasive surgery to be tes...

Background: Anorexia nervosa (AN) is a primary psychiatric disease, complicated by serious endocrine disturbances. Hypogonadotropic hypogonadism with primary or secondary amenorrhea is the most common endocrine repercussion of AN, with consequent estrogen deficiency and concerns about bone mineral density. Furthermore, establishing regular menstrual cycles is considered as one of the important milestones in girls treated for AN.Aim: To quantify the estro...
