Growth hormone deficiency (GHD) in children results in reduced adult height. Children with GHD typically require daily subcutaneous (s.c.) injections of growth hormone (GH). Daily injections are burdensome for both patients and their caregivers and reduced adherence negatively impacts clinical outcomes. Somapacitan (Novo Nordisk) is a long-acting reversible albumin-binding human GH derivative in development for once-weekly s.c. administration in children with GHD, aiming to ov...

Context: Polycystic ovary syndrome (PCOS) is defined by androgen excess and ovarian dysfunction in the absence of a specific physiological diagnosis. The best clinical marker of androgen excess is hirsutism, while the best biochemical parameter is still a matter of debate. Current consensus guidelines recommend serum free testosterone as the most sensitive serum parameter to measure androgen excess. Recently, however, novel active androgens and androgen metabo...

Introduction: Vitamin D status is investigated as a modifier for the risk and course of multiple malignant diseases. Findings point towards a detrimental role of low vitamin D levels for event free and overall survival (EFS/OS). However, vitamin D deficiency is often associated with secondary hyperparathyroidism, which may influence EFS/OS in childhood malignancies.Methods: Real world data from 1547 cases (873 male) of c...

We report on a 17-year-old female patient with cramps in hands and legs since 6 months. She showed hypokalemia with high need of potassium substitution (128mmol K= 1.3 mmol/kg/d), arterial hypertension (mean 154.5/92 mmHg), polydipsia and polyuria without nocturia or salt craving. Her PMH revealed neuroblastoma stage III with high-dose chemotherapy, stem cell transplantation and obesity (36.8 kg/m2). Further investigation showed aldosterone 77.5 ng/dl (norm values: 2-10ng/dl),...

Background: Polycystic ovary syndrome (PCOS) continues to be a diagnostic challenge in adolescent girls. Symptoms like oligomenorrhea and acne, and polycystic ovarian morphology on ultrasound can be normal variants in adolescents. In addition to diagnostic difficulties, there is lack of randomized controlled trials for PCOS treatments specific to adolescents. Current guidelines for diagnosis and management of PCOS in adolescents have large variations and rely ...

Introduction: Hypophosphatasia (HPP) characterized by reduced mineralization results from mutations in the tissue non-specific alkaline phosphatase (ALPL) gene. HPP is clinically variable with extensive allelic heterogeneity in the ALPL gene. We report the findings of in vitro functional studies following site-directed mutagenesis in bi-allelic mutations causing extreme clinical phenotypes; severe perinatal and asymptomatic HPP.<...

Background: Polycystic ovarian syndrome (PCOS) is common, affecting up to one-fifth of females. PCOS is associated with significant comorbidity including metabolic dysfunction, pro-inflammation and mood disorders. Despite this, it is poorly understood, and diagnosis and management remain challenging in adolescents. Proteomics enables the better understanding of disease mechanisms and facilitates the identification of novel biomarkers.<st...

Hypophosphatasia (HPP) is a rare, inherited, systemic disease characterized by deficient tissue-nonspecific alkaline phosphatase activity. Common manifestations in children include impaired skeletal mineralization, short stature, and reduced physical function. Asfotase alfa is an enzyme replacement therapy approved for treatment of patients of any age with pediatric-onset HPP. The utility of dual X-ray absorptiometry (DXA) as a diagnostic tool or measure of treatment effective...

Background: The incidence of ES in children varies greatly depending on the population surveyed, ranging from 1.2%-9% to 68% (children without and with known endocrinopathies, respectively). MRI is the main diagnostic tool for screening pituitary and in a previous KIGS study, 3.0% of patients with GHD were identified with ES and 7.8% with pituitary hypoplasia (Maghnie et al, EJE (2013).Aim: T...

Objective: Glioblastoma 2 (encoded by GLI 2 gene), is an activating zinc-finger transcription factor, involved in the Sonic Hedgehog pathway and embryogenesis of diencephalon and distal extremities Heterozygous mutations of GLI2 gene cause a wide range of clinical phenotype known as holoprosencephaly and holoprosencephaly-like syndrome, pituitary insufficiency, mid-facial hypoplasia, and polydactyly. We, herein, report a novel heterozygous IV...
