Background: Congenital central hypothyroidism (CeH) may occur isolated, or in combination with other pituitary hormone deficiencies. Although a third causative gene for CeH was recently reported (IGSF1), the aetiology of isolated CeH has remained unexplained in most cases.Objective and hypotheses: We hypothesized that in three relatives with unexplained isolated CeH a mutation in another gene might be responsible for the phenotype.<p class="...

IGFI and Relation to Growth in Infancy and Early Childhood in Very-Low-Birth-Weight Infants and Term Appropriate for Gestational Age Infants

Jong Miranda de , Cranendonk Anneke , van Weissenbruch Mirjam M.

Background: IGFI regulates early postnatal growth of preterm infants and also plays an important role in growth in childhood. Very-low-birth-weight (VLBW) infants are at risk for reduced growth in early childhood.Objective and hypotheses: To compare IGFI and the correlation to growth parameters in infancy and early childhood in VLBW and term appropriate for gestational age (AGA) infants.Method: We included 41 VLBW children and 64 t...

Impaired Motor Function in Turner Syndrome: What is the Relationship to Performal Intelligence Scores?

Taskin Betul , Verhaak Chris , Essink Marlou , Kempers Marlies , Vinck Anja , Sanden Ria Nijhuis-van der , Velden Janielle van Alfen-van der

Background: Although motor performance is often impaired in patients with Turner syndrome, the exact prevalence of motor problems is unknown. Detailed studies on specific motor profiles are lacking and the exact relationship between performal IQ and motor function is unknown.Aims and objectives: 1. To describe motor performance in our population of children and adolescents with Turner syndrome including the differentiation in specific motor skill domains...

Pathogenic variants in GHSR cause short stature and growth hormone neurosecretory dysfunction; results from a large case series

Introduction: Ghrelin binds to its receptor GHSR1A, encoded by GHSR, on somatotrophs of the pituitary. Growth hormone (GH) secretion is enhanced by ghrelin binding as well as the receptor’s constitutive activity. Results from in vitro experiments, knock-out mice, and GWAS suggest that heterozygous loss-of-function of GHSR may be associated with short stature, but observations in case studies are equivocal. We aimed to better ch...

Establishment of Reference Intervals for Hair Cortisol in Healthy Children Aged 0-18 Years Using Mass Spectrometric Analysis

de Kruijff Ineke , Noppe Gerard , Kieviet Noera , Choenni Vandhana , Lambregtse-van den Berg Mijke , Begijn Dominique , Tromp Ellen , Dorst Kristien , van Rossum Elisabeth , de Rijke Yolanda , van den Akker Erica

Background: Human scalp hair is a valuable matrix for determining long-term cortisol concentrations, with wide-spread applicability in clinical care as well as research. However, pediatric reference intervals are lacking.The aim of this study is to establish age-adjusted reference intervals for hair cortisol in children aged 0-18 years and to gain insight into hair-growth velocity in children up to 2 years old.Methods: A...

Alterations in resting-state functional connectivity in patients with congenital adrenal hyperplasia

Messina Valeria , van´t Westeinde Annelies , Padilla Nelly , Lajic Svetlana ,

Background: Patients with congenital adrenal hyperplasia (CAH) are treated with life-long glucocorticoid (GC) replacement therapy. Negative effects on cognition, brain structure and function during working memory tasks have been identified. To date, no studies on functional connectivity during rest have been performed in patients with CAH. One study conducted on patients with Cushing’s syndrome, another disorder of cortisol imbalance, suggests that long-t...

Avascular necrosis of the hip as a rare complication of growth hormone therapy

van der Linde Annelieke , van Baelen Amber , van Bergen Christiaan

Background: Growth hormone therapy can be indicated for children who are born small for gestation age (SGA) (either birth weight or birth height < -2 SDS) without catch-up growth (height < -2.5 SDS) at age 4 years. Growth hormone therapy is considered a safe treatment.Case presentation: A 12-year-old girl was referred to the pediatric endocrinologist for short stature. She was born small for gestational age (birth ...

Obesity in ROHHADNET Syndrome: Does Cortisol Play a Role?

van Tellingen Vera , van Trotsenburg Paul

Background: ROHHADNET syndrome is characterised by rapid onset childhood obesity, hypoventilation, variable hypothalamic-pituitary and autonomic dysfunction, and neuroendocrine tumors in 30–40%. Autoimmunity and paraneoplastic syndrome have been proposed as possible pathophysiological mechanisms, but the exact aetiology remains unclear.Objective and hypotheses: We present the clinical course of ROHHADNET syndrome in a 17-year-old girl, with consecut...

Recurrent Ketosis after Prolonged Exercise in Type 1 Diabetes: The Need for Glycogen Replacement Strategies: Case Report

van Albada Mirjam , van Waarde Willie Bakker

Background: In diabetic athletes, glycogen depletion can contribute to the early development of starvation ketones as is demonstrated by our patient.Case presentation: Our patient, a 15-year-old male triathlete with type 1 diabetes for 5 years was referred to our tertiary center because of suboptimal regulation on continuous subcutaneous insulin infusion (CSII). He frequently awoke with nausea and ketosis, which was initially attributed to failure of ins...

How do I manage severe obesity

van den Akker Erica

Pediatric severe obesity is a major threat to health and longevity. Around 7% of children worldwide have early onset severe obesity before the age of 7. Pediatric obesity is caused by an interplay of multiple factors: lifestyle, environmental, sociocultural, psychological, biological and genetic factors. Endocrine, monogenetic or syndromal causes are rare, but currently underdiagnosed and important to identify for the need of specific treatment. Cardiovascular risk factors and...
