Background: Homozygous aggrecan (ACAN) mutations have been described in a few skeletal dysplasias whilst more recently, heterozygous ACAN mutations have been reported in few families presenting with idiopathic short stature with advanced bone maturation and premature growth cessation.Case presentation: We describe two novel heterozygous ACAN stop mutations, detected using a skeletal dysplasia NGS panel and confirmed by Sanger sequencing...

Background: Many cross-sectional studies have demonstrated that serum testosterone concentration is an important biochemical predictor of bone mineral density in young males, but to our knowledge, no longitudinal studies have been carried out to support these cross-sectional data.Aims: to examine the associations between serum testosterone concentration at the age of 12 and the following gain in bone mineral density unti...

Introduction: Little is known about the effects of puberty suppression (PS) and hormone therapy (HT) on growth and adult height in transgender adolescents. These are topics of interest since height differs between sexes and some transgirls wish to limit their growth. In this longitudinal cohort study, we investigated the influence of PS and HT on growth and the efficacy of growth reduction therapy in transgender girls.Methods:</s...

Introduction: Global variations in epidemiology of type 1 diabetes (T1D) exist worldwide. This study is designed to determine the demographic and clinical characteristics of T1D in the past three decades, and to analyze changing trends in epidemiology over the past 50 years.Methods: Epidemiological and clinical characteristics of 925 patients with T1D were analyzed in three decades between 1991 and 2019. In addition, pre...

Background: Children with type 1 diabetes (T1D) and their parents need personalized i) information about the disease and glucose homeostasis and ii) knowledge and guidelines about diet and insulin therapy.Objectives: To set a complete educational program that allows children with T1D to improve disease management and daily life.Methods: Education modules were written and trained with children and parents at outpatient visits. Each ...

Introduction: Congenital Hyperinsulinism (CHI) is the most frequent cause of severe, persistent hypoglycemia in children. Despite current treatments, patients/caregivers report continued hypoglycemia according to the HI Global Registry 2020 Annual Report. Published literature characterizing hypoglycemia in CHI patients on standard of care (SOC) therapies is lacking.Objective: To quantify the extent of hypoglycemia in CHI...

Background: The short stature homeobox-containing (SHOX) gene, located in the telomeric pseudoautosomal region 1 (PAR1) on the short arm of both sex chromosomes, is important for linear growth.Objective and hypotheses: The aim of our study was to evaluate the presence of SHOX gene deletions/point mutations in children with short stature in order to understand the role of SHOX gene in idiopathic short stature (ISS) and estimate its frequency.<p class=...

Background: Previously we showed that pubertal children born small for gestational age (SGA) with a poor adult height (AH) expectation can benefit from treatment with GH 1 mg/m2 per day (~0.033 mg/kg per day) in combination with 2 years of GnRH analogue (GnRHa) and even more so with a double GH dose. GnRHa treatment is thought to have negative effects on body composition and blood pressure. Long-term effects and GH-dose effects on metabolic health in children treate...

Background: Adipose tissue (AT) in obesity is characterized by low grade inflammation. The apoptosis inhibitor of macrophages (AIM; also called CD5L) is incorporated into adipocytes leading to increased lipolysis. Excess AIM-dependent lipolysis induces adipose tissue macrophage recruitment. M1 (proinflammatory) macrophage infiltration, with surface marker CD40, correlates with metabolic complications.Objective and hypotheses: To study serum levels and AT...

Background: The Low dose dexamethasone suppression test (LDDST) is an important investigation for suspected Cushing’s Syndrome (CS). The traditional definition of normal suppression of serum cortisol to ≤50 nmol/l during the LDDST (0.5 mg 6 hrly × 48 h) comes from a time when biochemical autoanalysers did not routinely detect very low values. Previous studies reported 5.1–8.3% of patients with Cushing’s Disease (CD) suppressed to <50 nmol/l at 48 ...
