Background: Congenital adrenal hyperplasia (CAH) arises from mutations in CYP21A2 gene, which encodes for the steroidogenic enzyme 21-hydroxylase. Currently employed chorionic villus sampling and amniocentesis provide genetic results at ~14 weeks of gestation at the earliest. At this time, the genitalia of the affected female foetuses have already become virilized. To prevent genital ambiguity, prenatal treatment with dexamethasone must begin on or before gestational ...

Introduction: The mechanisms underlying short stature in Noonan Syndrome (NS) are poorly understood and may include inadequate GH secretion or action, decreased IGF-1 production, growth plate dysfunction, or other factors. In this retrospective study, we aimed to evaluate the function of the GH-IGF-1 axis in NS.Method: We took all patients with genetically proven Noonan syndrome among 1001 children and adolescents curren...

Background: The genetic etiology of SGA-SS spans from abnormalities of the GH-IGF-1 axis, growth plate disorders, and defective fundamental intracellular/intranuclear processes, to imprinting conditions. We recently elucidated the genetic etiology in a large cohort of 74 children SGA-SS (Toni L et al, Horm Res Pediat 2024; 97(1): 40-52). Of these, 49 have already completed five years of daily GH therapy.Aim: To analyze 5...

Objective: This study aims to assess the potential predictive value of impulse oscillometry (IOS) and hepatic fat content as an alternative diagnostic tools to polysomnography (PSG) for obstructive sleep apnea syndrome (OSAS) in obese children and adolescents.Method: The study included obese children with a body mass index (BMI) above the 95th percentile. OSAS was assessed via PSG in obese children. Hypopnea was defined ...

Objective: The objective of this study was to investigate the clinical presentations, laboratory findings, treatment modalities, follow-up strategies employed for children with levothyroxine (LT4) poisoning.Materials-Methods: The study encompassed patients admitted to the respective centers between 2010-2023, who fulfilled the predefined study criteria. Findings were presented as percentages (%), median values with inter...

Background: Follicle-stimulating hormone (FSH) plays a key role in reproduction. The G-protein coupled FSH receptor (FSHR), is expressed primarily in gonads, and specifically binds FSH. FSHR is also expressed in vascular endothelium, osteoclasts, adipose tissue, monocytes and rodent pancreatic islets. Elevated FSH levels are associated with development of obesity, insulin resistance, osteoporosis, and cardiovascular disease. In a recent study, we showed that h...

Background: Congenital combined pituitary hormone deficiency (cCPHD) is the loss of ≥2 pituitary hormones caused by genetic or prenatal factors.Methods: For the period 1996–2020, patients with cCPHD were identified from the Danish National Patient Registry and the registries at the four Danish hospitals approved for the management of cCPHD. Retrospective hospital file reviews were performed to validate the diagn...

Introduction: When used to treat obesity, glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1RA) improve both BMI and metabolic health. Liraglutide is approved by both the EMA and FDA for the treatment of pediatric obesity, from 12 years and older. However, 26 weeks after discontinuation of liraglutide, the weight lost during treatment is regained. Prolonged exogenous stimulation of hormone-specific receptors may influence endogenous hormonal regulation. ...

Background: Childhood growth is an indicator of health/well-being. Growth monitoring identifies treatable conditions in apparently healthy children and prevents inappropriate referrals. Systematic growth monitoring is not currently a UK priority and growth disorders are frequently diagnosed late.Objective: Develop and test the accuracy of GrowthMonitor, an app which enables families to measure a child’s height at h...

Background: Hypotonia-Cystinuria Syndrome (HCS) is a rare autosomal recessive disease characterized by generalized hypotonia, nephrolithiasis, short stature, minor facial dysmorphism, hyperphagia, and rapid weight gain in late childhood. Microdeletion can be detected in part of the SLC3A1 and PREPL genes in these cases. Growth hormone deficiency is rarely seen in these patients and adequate growth can be achieved with growth hormone therapy.<p class="abste...
