Diagnosis of PCOS in Adolescents Using MRI

Maxime Fondin , Antoine Rachas , Van Huynh , Abella Stephanie Franchi , Jean-Paul Teglas , Lise Duranteau , Catherine Adamsbaum

Background: Polycystic ovarian syndrome (PCOS) diagnosis includes ovarian morphology using transvaginal ultrasound (US). However transvaginal US cannot be used in virginal girls and transabdominal US is not optimal particularly in obese patients.Objective and hypotheses: To evaluate the validity and reproducibility of ovarian morphology measures using MRI for the diagnosis of PCOS in adolescents.Method: This case-control study (200...

Different Long-term Neurodevelopmental Outcomes in Very Preterm Versus Very-low-birth-weight Infants

Hollanders Jonneke J , Schaefer Nina , van der Pal Sylvia M , Rotteveel Joost , Finken Martijn J J

Background: Birth weight (BW) is often used as a proxy for gestational age (GA) by studies on preterm birth. Recent data indicate that the terms very-low-birth-weight (VLBW; BW <1500 g) and very preterm (VP; GA <32 weeks) birth are not equivalent with regard to perinatal outcomes and postnatal growth up until final height. It is unknown whether the differences between these terms could be extended to long-term neurodevelopmental outcomes.Objectiv...

Genetics of Growth Failure in Small for Gestational Age Children

Keppler Romy , van der Werft-Grohmann Natascha , Schwab Karl Otfried , Lausch Ekkehart

Background: Small for gestational age (SGA), defined as ≤−2.0 SDS birth length or weight, is a condition seen in up to 3% of all newborn. Most SGA children catch up height in postnatal life. In a significant number (~10%), however, height remains below the third centile. Recombinant GH therapy is indicated when growth failure continues to 4 years of age. The pathophysiological basis of SGA is complex: monogenic disorders and/or fetal programming by environmental fa...

Beneficial Effects of Long-term GH Treatment on Adaptive Functioning in Infants With Prader–willi Syndrome

Lo Sin , Festen Dederieke , van Wijngaarden Roderick Tummers-de Lind , Collin Philippe , Hokken-Koelega Anita

Background: Knowledge about the effect of GH treatment on adaptive functioning in children with Prader–Willi syndrome (PWS) is limited.Objective and hypotheses: The aim of this study was to investigate the effect of GH treatment on adaptive functioning in children with PWS.Method: Vineland Adaptive Behavior Scale (VABS) was assessed at start, at the end of the RCT, and after 7 years of GH treatment. In the RCT, 75 children (42...

Early Medical Treatment of Children with Gender Dysphoria: an Empirical Ethical Study on Arguments of Proponents and Opponents Concerning Early Interventions

de Vries Martine , Vrouenraets Lieke , Wichmann Anne , Schermer Maartje , Fredriks Miranda , Delemarre-van de Waal Henriette

Background: Both The Endocrine Society and the World Professional Association for Transgender Health (WPATH) published guidelines for the treatment of children and adolescents with gender dysphoria (GD). The guidelines recommend the use of GnRH agonists in adolescence to suppress puberty, and the use of cross-sex hormones starting around age 16 for eligible patients. In actual practice, there is no consensus whether to use these early medical interventions. The aim of our stud...

Response to GH Treatment in Patients with Silver Russell Syndrome

Smeets C C J , Renes J S , van der Steen M , Hokken-Koelega A C S

Background: Silver Russell syndrome (SRS) is characterized by low birth weight, severe postnatal short stature and distinctive facies. In ~50% of patients, (epi)genetic alterations can be detected (~40% hypomethylation of H19 on chromosome 11, ~10% maternal uniparental disomy (UPD) 7). As SRS patients are usually born small for gestational age (SGA), they are treated with GH to improve height. However, data on long-term effects of GH treatment in SRS patients are very limited....

Endocrine Abnormalities in Phosphoglucomutase 1 Deficiency

Mueksch Barbara , Morava Eva , Lefeber Dirk , Claahsen-van der Grinten Hedi , Korsch Eckhard

Introduction: Phosphoglucomutase 1 catalyzes the interconversion of glucose-6-phosphate and glucose-1-phosphate. Phosphoglucomutase 1 deficiency (PGM1-CDG), previously termed glycogenosis type XIV (OMIM 612934), is a rare variant of the congenital disorders of glycolysation (CDG), resulting in abnormal attachment and processing of protein linked N-glycans. We present a girl with PGM1-CDG and delayed pubertal development and review the endocrine findings of the few pat...

Increased Required Dose of GH in Children with Inborn Panhypopituitarism

Wurm Michael , van der Werf-Grohmann Natascha , Krause Alexandra , Roemer-Pergher Cordula , Schwab Karl Otfried

Introduction: Standard dose for GH deficient children is 0.025 mg/kg per day given subcutaneously once daily. Inborn panhypopituitarism is a special subset of GH deficiency. Its management is difficult because several hormones need to be replaced. We present three patients with perinatal onset panhypopituitarism.Case reports: Case 1 is a 7-year-old boy who had hypoglycaemic seizure with reanimation due to circulatory arrest shortly after birth. Panhypopi...

Lack of Association between Transient Hypothyroxinaemia of Prematurity and Neurodevelopmental and Behavioral Outcomes in Young Adulthood

Hollanders Josephina J , Israels Joel , van der Pal Sylvia M , Rotteveel Joost , Finken Martijn J J

Background: Preterm newborns are at risk of becoming transiently hypothyroxinaemic, which has been associated with neurodevelopmental impairments in childhood. It is not known whether these associations persist into adulthood.Objective and hypotheses: We studied the relation between transient hypothyroxinaemia of prematurity and IQ, neuromotor functioning and problem behaviour at young adult age.Method: This was a prospective study...

RM-493, a Melanocortin-4 Receptor (MC4R) Agonist, is Being Therapeutically Evaluated in Patients with Deficiencies in the Leptin – Proopiomelanocortin (POMC) – MC4R Hypothalamic Pathway, Including Prader–Willi Syndrome (PWS)

Kuhnen Peter , Krude Heiko , Wiegand Susanna , van der Ploeg Lex , Fiedorek Fred , Hylan Michelle , Gottesdiener Keith

Background: The hypothalamic leptin–melanocortin signalling pathway is a critical regulator of human appetite and weight regulation. Monogenetic defects in the POMC gene, the MSH ligand generating PC1 gene and the MSH receptor gene MC4R lead to severe early onset and leptin-resistant obesity. In PWS, where the function of genes such as MAGEL2 are impaired, the Magel2-/- mouse model revealed decreased POMC neuronal functioning as one c...
