Concurrent premature gonadotrophic activation and gonadal insufficiency in young girls with a brain tumor

Evelein Annemieke , Schouten - Van Meeteren Netteke , Bakker Boudewijn , Gidding Corrie , Van der Wetering Marianne , Van Santen Hanneke

Background: It is well known that endocrine comorbidities occur frequently in children with cancer, especially in those with a brain tumor. In those children, increased intracranial pressure or hydrocephalus may lead to central precocious puberty. Furthermore, chemotherapy, especially alkylating agents, increases the risk for gonadal insufficiency. In this case series we describe 3 young girls with a brain tumor, who develop premature gonadotrophic activation,...

Curve matching to predict future growth in patients receiving recombinant human growth hormone: an interpretable and explainable method using big data

van Dommelen Paula , Arnaud Lilian , Koledova Ekaterina

Background: Prediction models demonstrate potential in predicting growth in patients receiving recombinant human growth hormone (r-hGH) for growth disorders. However, considerable information from patients is needed to calculate a predicted growth curve. The curve matching technique only requires height data. This technique identifies growth curves that are similar (matched) among real-world patients within a database. The growth curves of these ‘matched...

Real-World Data From Electronic Monitoring of Adherence to Growth Hormone Treatment in Children with Growth Disorders: A Descriptive Analysis

Koledova Ekaterina , Tornincasa Vincenzo , van Dommelen Paula

Poor adherence to long-term growth hormone (GH) treatment can lead to suboptimal clinical outcomes. The easypod™ connect eHealth platform enables healthcare professionals to obtain an accurate picture of real-world adherence by allowing patients to transmit adherence data to a database. Our aims were to assess adherence to r-hGH (Saizen, Merck KGaA, Darmstadt, Germany) treatment with the easypod connect platform in children from treatment start to 48 months and to investi...

Follow-up to Adulthood of Two 46,XY Siblings with 5-alpha Reductase Deficiency and Different Sex of Rearing

Chiniara Lyne , Sandberg David , Van Vliet Guy

Background: 46,XY patients with 5α-reductase deficiency (5-ARD), reared from birth as girls, are reported to self-reassign as boys subsequent to a masculinizing puberty; whether this holds true in cases of early orchidectomy is less well documented.Objective and hypotheses: Prepubertal orchidectomy reduces the likelihood of gender self-reassignment.Method: Presentation, management and outcome of two siblings with 5-ARD with na...

Characteristics of a Population of Obese Children and Adolescents: Suggesting a New Paradigm

Van Meter Quentin , Welstead Bethany , Low Joey

Background: Obese children come from families where either one or both parents are obese, suggesting obesity is the result of exposure to detrimental environment.Objective and hypotheses: We propose that inherited insulin resistance is the core which promotes development of obesity and that allergic airway obstruction stalls development of obesity, while peptic gastritis promotes over-eating by confounding portion control.Method: W...

Impact of the COVID-19 pandemic and related lockdown measures on lifestyle behaviours and quality of life in children and adolescents with severe obesity

Welling MS , Abawi O , van den Eynde E , van Rossum EFC , Halberstadt J , Brandsma AE , Kleinendorst L , van den Akker ELT , van der Voorn B ,

Introduction: Lockdown measures following the COVID-19 pandemic are shown to have greatly affected lifestyle behaviours and health-related quality of life (HRQoL) of children. The impact on children with severe obesity has not yet been described. Aim of this study was to investigate the impact of COVID-19 lockdown on eating behaviours, physical activity (PA), screen time, and HRQoL of children (including adolescents) with severe obesity....

Primary Hyperparathyroidism caused by a Mutation of the Vitamin D Receptor Gene

de Beldjenna Liliana Mejia de Beldjenna L

Objective: To present a patient with hypercalcemia caused by a parathyroid adenoma and a deletion of the VDR gene.Case clinic: The case is that of a 13-year-old male who presented with hypercalcemia, muscle weakness, nephrocalcinosis, two pathological fractures and a family history of nephrocalcinosis. Physical examination was unremarkable, except the presence of a fracture of the left femur. Laboratory findings: Total s...

Introduction: Congenital adrenal hyperplasia (CAH) is the most common genetic condition in the spectrum of differences of sex development (DSD). Surgery in DSD is a controversial topic and there is no consensus if to perform surgery, how to perform surgery, and when to perform surgery. The current study was designed to evaluate the current practice in CAH related surgical practice in girls.Patients and Methods: All cases...

Congenital adrenal hyperplasia in detail: A multicentric and interdisciplinary study in minors with different sexual development

Ignacio Diez-Lopez , Nerea Gonzalez-Temprano , Villalon Flor , Larreina de la Fuente Leire , Cancela Vanesa , Nuñez Francisco Javier , Hernandez Jone Miren

Of the 67 included DSD patients, 33% were HSCs. 68% women and 32% men, with a total concordance between legal sex, current gender and chromosomal sex. Median age: 10.5 years, IQR 8-14. The most frequent clinical form was non-classical (NC) 45.5%, followed by classical with saline loss (CPS) 41%. The distribution of each clinical form according to the karyotype is significant (P = 0.013), the most frequent with XY karyotype is CPS and in NC forms all cases are XX. Med...

Very preterm infants developing BPD have increased levels of the cortisol precursors 17-OH progesterone and 11-deoxycortisol

Romijn Michelle , Onland Wes , van Keulen Britt , Heijboer Annemieke , Rotteveel Joost , van Kaam Anton , Finken Martijn

Rationale: Bronchopulmonary dysplasia (BPD) is a major complication of preterm birth, which pathophysiology involves systematic inflammation. Preterm infants commonly suffer from relative adrenal insufficiency (RAI) in their first week of life, resulting in an insufficient production of cortisol inappropriate for the degree of inflammation. One of the major causes of RAI is immaturity of adrenal cortex enzymes, leading to an accumulation of cortisol precursors...
