Complications after pediatric thyroidectomy: lymph node dissection is a risk factor for permanent hypocalcemia

van Rooijen Jesse J. , Paul van Trotsenburg A.S. , Zwaveling-Soonawala Nitash , Nieveen van Dijkum Els J.M. , Engelsman Anton F. , Derikx Joep P.M. , Mooij Christiaan F.

Background: Thyroidectomy is a definitive treatment option in some benign thyroid disorders and the definitive treatment option for thyroid cancer. As postoperative mortality is extremely rare data on postoperative complications and long-term health consequences are important.Objective: To evaluate the frequencies of short- and long-term complications, and their risk factors in pediatric patients (0-18 years) who underwent a thyroidectomy in a tertiary c...

Resting energy expenditure and body composition in children and adolescents with severe obesity due to (suspected) medical causes: comparison between different subtypes of obesity

Abawi Ozair , Koster Emma , Welling Mila , Boeters Sanne , van Rossum Elisabeth , van der Voorn Bibian , de Groot Cornelis , van den Akker Erica ,

Background: Paediatric obesity is a multifactorial disease characterized by an imbalance between energy intake and expenditure. In rare cases, obesity is caused by underlying medical disorders arising from disruptions in the leptin-melanocortin pathway, which regulates satiety and energy expenditure.Aim: To investigate resting energy expenditure (REE) in relation to body composition in children and adolescents with sever...

Clinical characteristics of heterozygous ACAN gene variants and longer-term response to growth hormone treatment: real-world data

Renes Judith , Reedijk Ardine , Losekoot Monique , Kant Sarina , van der Steen Manouk , van der Kaay Danielle , Hokken-Koelega Anita , van Duyvenvoorde Hermine , de Bruin Christiaan

Background: Heterozygous pathogenic variants in the ACAN gene underlie disproportionate short stature with characteristically accelerated bone age (BA) maturation and/or osteochondritis dissecans (OD)/early-onset osteoarthritis (OA).Objective: To describe the phenotypic spectrum and assess the response and safety of growth hormone (GH) treatment in children with a heterozygous pathogenic ACAN variant.</...

Introduction: Childhood craniopharyngioma (cCP) has excellent survival, but quality of life may be severely hampered by hypothalamic dysfunction. We aimed to evaluate treatment and hypothalamic outcomes of a Dutch cCP cohort, and evaluate the effect of centralization of care.Methods: A retrospective cohort study was performed, including cCP patients diagnosed between 2004-2021. Treatment characteristics and hypothalamic ...

Clinical features and response to rhGH treatment in ten patients with heterozygous IGF1 variants

Punt Lauren , van der Kaay Danielle , van Setten Petra , Bocco Gianni , de Munnik Sonja , Losekoot Monique , van Duyvenvoorde Hermine , de Bruin Christiaan , Maarten Wit Jan , Joustra Sjoerd

Introduction: Patients carrying homozygous IGF1 loss-of-function mutations are extremely rare and show severe pre- and postnatal growth failure, microcephaly, developmental delay, retrognathia and sensorineural deafness. Heterozygous variants in IGF1 appear to be more common in short stature, but only few cases have been reported in detail. Therefore, clinical features and growth response to recombinant human growth hormone (rhGH) therapy are...

Puberty induction in boys with CHARGE syndrome and hypogonadism: experiences of patients, parents and doctors

Dijk Dieuwerke , Bocca Gianni , Ranchor Adelita , Van Ravenswaaij-Arts Conny

CHARGE syndrome is a rare and complex disorder with an incidence of 1:15000 to 1:17000 live births. It is associated with a wide range of issues, including, but not limited to, coloboma of the eye, congenital heart disease, atresia of the choanae, retardation of growth and development, hypogonadotropic hypogonadism, ear abnormalities and hearing loss. Hypogonadotropic hypogonadism is present in 60-88% of individuals with CHARGE syndrome. In these patients, hormone replacement ...

A Rare Case of Pseudoisodicentric X Chromosome in a Patient with Primary Amenorrhoea

Schipper Saskia , Aarts Coranne , van der Linde Annelieke

Background: Pseudoisodicentric X chromosomes with an Xq deletion (46,X,idic(Xq)) are rare. Most cases are mosaic, the other cell line being 45,X. Nonmosaicism is rare. Phenotype is characterized by the resultant of the X deletion. Variations from short to tall stature can occur and premature ovarian failure is a common feature.Case presentation: A 16 year old girl was referred to our clinic with primary amenorrhoea. She ...

Individual Patterns of Objectively Measured Adherence to Growth Hormone Treatment and its Effect on Growth in Prepubertal Children with Growth Hormone Deficiency

van Dommelen Paula , Wit Jan M , Koledova Ekaterina

The easypod™ electromechanical injection in combination with the easypod Connect platform electronically records and transmits, in real time, accurate, objective records of the date, time and dose injected for patients receiving Growth Hormone (GH) for growth disorders, limiting the risk of misreporting and allowing physicians to accurately monitor patient behavior.The aim was to study individual patterns of adherence from start treatment up to 24 m...

Refractory Cyclical Cushing’s Disease - a Case of Multiple Pituitary Micro-adenomas in a Three Year Old Girl after 8 Years Follow up

Robinson Elizabeth , Poonam Poonam Dharmaraj , Heyningen Carl van

Case presentation: A 3 years 10 months old British white girl presented with rapid weight gain of 11 kg over 4 months, hirsutism, central obesity, moon face, buffalo hump and hypertension.Investigations: Plasma cortisol, IGF-1 and ACTH levels were elevated. The 9am plasma cortisol was 1035 nmol/l (140–500) with simultaneous plasma ACTH 13 pmol/l (1–11). Plasma cortisol and ACTH levels responded to both dexamethasone suppression and CRH stimulat...

Chronotype and Type 2 Diabetes Risk in Preadolescents

Dumin Magdalena , O'Sullivan Katie , Van Cauter Eve , Koren Dorit

Background: An individual’s chronotype, or preference in the timing of sleep or food intake, may have metabolic implications. Late chronotype has been associated with higher body mass index (BMI) and hemoglobin A1c (HbA1c) in adults and greater BMI, portion sizes, and lower HDL cholesterol levels in adolescents.Objective and hypothesis: To examine associations between chronotype and risk factors for type 2 diabetes in children ages 10–13 years....
