Background: Disorders related to an impairment in parathyroid hormone (PTH) signaling pathway are historically classified under the term pseudohypoparathyroidism (PHP), that now encompasses rare, related but highly heterogeneous diseases with demonstrated (epi)genetic causes. The actual classification is based on the presence or absence of specific clinical and biochemical signs together with an in vivo response to exogenous PTH and an in vitro assay of Gs&#9...

Background: Obesity is characterized by an increase in fat mass caused by an increase in adipocyte number and adipocyte size and is often associated with adipose tissue (AT) dysfunction contributing to metabolic impairment. It is suspected that adipocyte progenitor cells play an important role during healthy and obesity-related AT expansion. Studies in adults showed that the stroma vascular fraction (SVF) of AT is composed of different progenitor cell subpopul...

A ten year old girl was brought by the emergency mobile service for a persistent status epilepticus despite administration of Diazepam on site. She had presented headaches for the last three days and one episode of fever was suspected but not measured four days earlier. She had one episode of dizziness five days earlier.Persistent status epilepticus required invasive ventilation as well as deep sedation with Levetiracetam, Midazolam, ketamine, phenytoin,...

Background: Clinical observations of children and adolescents with differentiated thyroid cancer (DTC) patients led us to investigate quality of life and anxiety. Although adult DTC survivors have similar or slightly worse quality of life (QOL), this has not been evaluated in the pediatric population.Objective and Hypotheses: In this cross-sectional pilot study, our objective was to compare QOL and anxiety in adolescents with DTC to patients with acquire...

Background and Aim: A substantial proportion of SGA patients have a syndrome underlying their growth restriction. Most SGA cohorts comprise both syndromic (S-SGA) and non-syndromic patients (nonS-SGA) impeding delineation of the recombinant human growth hormone (rhGH) response. We present a detailed characterization of the Belgian SGA cohort and analyze rhGH response based on adult height (AH).Patients & Methods: Cli...

Background: In the past, the majority of the pacients with Type 1 Diabetes (DM1) had late puberty due to hipogonadotropic hipogonadism as a result of insulin deficiency. However, the use of intensive insulin therapy nowadays, results in higher BMI what can lead to an earlier puberty. Insulin administered subcutaneously is not processed by the liver, which implies increased exposure to this hormone in the ovary leading to greater activation of theca and granulo...

Background: The growth and IGF1 responses to GH treatment show a large variation across children with idiopathic short stature (ISS). Compliance and GH regimens are important determinants. The d3 variant of the GH receptor (GHR) is a significant genetic predictor. The role of individual epigenetics had not been studied. The IGF1 locus is an attractive candidate where CG methylation could influence GH action.Objectives: To study GH effects on a) IGF1 gene...

Background: Medullary thyroid cancer (MTC) in MEN 2A is caused by mutations in RET. Guidelines (2001/2009/2015) recommend prophylactic total thyroidectomy (TT) based on mutation specific risk levels (ATA 2015: high/moderate).Objective: The aim of this study was to analyse changes of age at TT, frequency of metastatic MTC (MMTC), and frequency of TT according to guidelines since introduction of RET testing in 1995....

Background: Short stature has several causes ranging from complex hormonal deficiencies mostly related to pituitary gland genetics, to idiopathic and environmental causes such as maternal smoking in pregnancy, etc. Floating harbor syndrome is a rare genetic disorder characterized by short stature, delayed bone age, mild to moderate mental retardation, retarded speech development, and typical facial dysmorphic features. The syndrome is caused by heterozygous mutations in exon 3...

Background: The thyroid gland is a common unintended target during and after cancer treatment in childhood cancer survivors. However, only a limited number of studies have assessed thyroid adverse events of newer or more selective anticancer drugs. The main objectives of this review are to provide an overview of thyroid disorders in children, treated with 131 I-metaiodobenzylguanidine (131 I-MIBG), tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibi...
