The effects of dextroamphetamine treatment in children with hypothalamic obesity

Samaan J , Welling MS , de Groot CJ , Abawi O , Burghard M , Kleinendorst L , van der Voorn B , van Haelst MM , Oude Ophuis B , Kamp GA , Rotteveel J , van Schouten-Meeteren AYN , van den Akker ELT , van Santen HM ,

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,...

Elevated Anti-tissue Transglutaminase Antibodies in Children Newly Diagnosed with type 1 Diabetes do not Always Indicate Celiac Disease

Paketçi Ahu , Armagan Coskun , Erbas İbrahim Mert , Demir Korcan , Abaci Ayhan , Böber Ece

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...

Gonadotropin-Dependent Pubertal Disorders are Common in Patients with Virilizing Adrenocortical Tumors in Childhood

Stecchini Monica F , Braid Zilda , More Candy B , Aragon Davi C , Castro Margaret , Moreira Ayrton C , Antonini Sonir R

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 (...

Ultrasound-Based Measurements of Testicular Volume in 6–16 Year Old Boys: Intra- and Inter-Observer Agreement and Comparison with Prader Orchidometry

Oehme Ninnie , Roelants Mathieu , Bruserud Ingvild Saervold , Egil Eide Geir , Bjerknes Robert , Rosendahl Karen , Juliusson Petur B

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...

Steroidogenesis in the Human Fetal Adrenals at the End of the First Trimester

Savchuk Iuliia , Morvan M.L. , Soeborg T. , Antignac J.P. , Danielsson K. Gemzell , Bizec B. Le , Soder O. , Svechnikov K.

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</...

Gender Identity Prediction in Adulthood by HTP Test (House-Tree-Family) in 46, XY DSD Patients

Batista Rafael Loch , Inacio Marlene , Oliveira Jr Ari , Brito Vinicius N , Costa Elaine M F , Domenice Sorahia , Mendonca Berenice B

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...

Profiling of a Novel NSIAD-Causing Mutation of Vasopressin Receptor 2 and its Differential Effect on Receptor Trafficking Compared to Previously Identified Mutations

Tiulpakov Anatoly , White Carl W , Abhayawardana Rekhati , Zubkova Natalia , Seeber Ruth M , See Heng B , Pfleger Kevin D G

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...

Assessment of DRD2 dopamine receptor gene rs6277 in pediatric obesity: a case-control study

Machado Pinto Renata , Alves Nygell S , Fortes Jakeline S , Monteiro Rubia V , Minasi Lysa B , da Cruz Aparecido Divino ,

Introduction: Obesity is a multifactorial disease resulting from an interplay between genetics and the environment. Metabolic, nutritional, psychosocial, and lifestyle factors participate, promoting various degrees of overweight or obesity. Pediatric obesity increases after infancy and is higher in early adulthood, showing a heritability of up to 85%. Genetic variants associated with BMI in children can exert their effects by affecting eating behavior, as is t...

Polygenic scores for testosterone and SHBG are associated with hormone levels in male infants

Siegfried Busch Alexander , Lindhardt Ljubicic Marie , N. Upners Emmie , B. Fischer Margit , P Hagen Casper , Juul Anders

Background: The male Hypothalamic-Pituitary-Gonadal (HPG) axis undergoes a transient activity phase during the first months of life with surging serum concentrations of reproductive hormones. Theoretically, the hormonal surge could represent a passive postnatal feedback to the withdrawal from the high sex steroid levels in pregnancy. However, we believe that minipuberty rather represents an active, tightly genetically-regulated biological process. We therefore...
