Introduction: Anorexia nervosa (AN) is a psychiatric disorder affecting mainly adolescents and young women, characterized by a restriction of energy intake leading to malnutrition, serious medical complications and high mortality. Until now the etiology of AN remains unknown and seems to be multifactorial. Patients with AN develop endocrine disorders related to disturbances of energy metabolism. Nesfatin-1 and glucagon-like peptide-1 (GLP-1) are involved in th...

Hypoplastic left heart syndrome (HLHS) is one of the most severe congenital heart defects. Despite medical progress, HLHS patients remain at risk of many complications of this cardiac defect and cardiac surgery, including growth failure. Some of them can be treated with recombinant human growth hormone (rhGH) fulfilling criteria of GH–deficiency (GHD) or having a history of intrauterine growth restriction or small for gestational age (SGA). We assessed the effectiveness ...

It is estimated that single-gene mutations are responsible for 3-10% of childhood obesity cases. The most common of these is a mutation in the MC4R gene, occurring in about 1-6% of children and 1% of adults with early-onset severe obesity. We report on of 7-year-old male twins with severe obesity (86% and 75% excess body mass relative to height), starting from the second year of life, along with hyperphagia. The boys were born from a twin pregnancy, PIII, CC, at 37 weeks of ge...

Introduction: Children with hypothalamic dysfunction, e.g. due to a genetic or acquired cause such as suprasellar tumours, often suffer from hyperphagia and/or decreased resting energy expenditure (REE). This process induces uncontrollable weight gain, resulting in severe hypothalamic obesity (HO). No effective treatment is available yet for HO. Amphetamines are psychostimulants that are known for their appetite reducing and REE stimulating side effects. Here,...

Introduction: The prevalence of celiac disease is 5–10 times higher in patients with type 1 diabetes mellitus (DM) than in the general population. Therefore, celiac serology should be screened intermittently in type 1 DM patients. However, anti-tissue transglutaminase (anti-TTG) antibody elevation may be detected incidentally at the time of type 1 DM diagnosis and regress spontaneously during follow-up, without medical or dietary interventions.<p clas...

Background: In pediatric patients with adrenocortical tumors (ACT), morbidity and mortality rates have been extensively evaluated. However, there are almost no data on the late consequences of early exposure to high androgen levels on pubertal development and on final height (FH) in these patients.Objective: To investigate the impact of early exposure to androgen excess on gonadotropin-dependent pubertal development and on final height (...

Background: Prader orchidometry has been the standard method for evaluating testicular size. As this technique is subjective and tends to overestimate the testicular volume, ultrasound has been proposed as a more reliable method.Objective: To evaluate the intra- and inter-observer agreement of ultrasound measurements of testicular volume and comparison with Prader orchidometry.Materials and methods: Length, width and depth of the r...

Background: Steroid hormones produced by the human fetal adrenals (HFA) are suggested to regulate intrauterine homeostasis and the maturation of certain fetal organs necessary for extrauterine life. Appropriate development and hormonal function of the HFA therefore are critical for normal fetal maturation and survival. Little is known about the possible relationship between the expression of steroidogenic enzymes and corresponding transcription factors in the HFA in vivo</...

Background: Patients with 46, XY DSD present conflicts and issues related to gender identity (GI) and change to male social sex in patients registered in the female social sex is not rare. The HTP test is a projective psychological test, which assesses aspects related to sexual identification. GI in this test is defined as female (F), male (M) or ambiguous.Objective and hypotheses: To evaluate GI in patients with 46, XY DSD by the HTP test and compare th...

Background: Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) results from gain-of-function mutations in the AVPR2 gene coding for vasopressin receptor 2 (V2R). In contrast, nephrogenic diabetes insipidus (NDI) is caused by loss-of-function mutations in AVPR2. Here we describe and functionally characterize a novel mutation located in the seventh transmembrane domain of V2R. This mutation was identified in a boy suffering from water-induced hyponatrem...
