Background: Familial hypercholesterolemia (FH) leads to markedly elevated circulating levels of low-density lipoprotein cholesterol (LDL-C) and is associated with a significantly increased cardiovascular mortality already in childhood and adolescence. FH is caused by dominant mutations in the genes encoding LDL-receptor (LDLR), ApoB-100 and protein convertase subtilin/kexin9 (PCSK9), whereas rarely recessive forms due to mutations in LDL receptor adaptor protein 1 (LDLRAP1...

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...

Title: The making of the EndoWatch: A new device for Early Monitoring of Hypothalamic imbalances. Hulsmann S, Petras S, Fraboulet P, Yuan Lu, van Santen HM (on behalf of the EndoWatch team) Keywords: Paediatric and adolescent cancer survivors, Brain tumour, Quality of Life, Wearable, Hypothalamic Obesity Main goals: Aim for better quality of lifeIntroduction: Children and adults with a suprasellar (hypothalamic)...

Background: The positive effect of GH therapy in small for gestational age (SGA) singletons has been shown in previous studies. Little is known about twin growth and GH treatment where only one twin is born SGA.Objective and hypotheses: We present data from two set of twins where one was appropriate for gestational age (control) and the other twin was SGA (treatment).Method: Twin pair 1: male monochorionic diamniotic (MCDA) twins b...

Background: McCune–Albright syndrome (MAS) is defined by skin, bone and glands disorders, due to activating mutations in the GNAS1. Clinical presentation is heterogeneous. Reports about GH excess in MAS patients are scarce.Case report: We present the case of an 8-year-old male, previously diagnosed with mono-ostotic fibrous dysplasia of the skull, referred due to signs of pubertal development since the age of 6. The patient presented only 1...

Background: Postnatal linear growth is characterized by a steady decline of growth velocity in healthy individuals, with the exception of sex-steroid induced pubertal growth. Pharmacologic interventions in growth disorders are limited to systemic application of growth factors such as growth hormone, and CNP analogues in conditions with FGFR3 overactivation. Tyrosine kinase receptor inhibitors (TKI) represent a heterogenous group of drugs, mostly used for oncol...

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 ...

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...

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...

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...
