Introduction: Aromatase inhibitors (AIs) are increasingly used in children and adolescents to augment adult height. Given the potential risks of these drugs in women with breast cancer, detailed cardiovascular examinations in adolescents using these treatments are needed to ensure their safety in the pediatric group. The aim of this study was to investigate the effects AIs on cardiac morphology, functions and their relation to several metabolic parameters in a...

Introduction: In rare cases of obesity, genetic defects lead to hyperphagia and severe early-onset obesity. Genetic testing in patients with a suspected genetic obesity phenotype is important, as it can lead to patient-tailored treatment advice. For children, the Endocrine Society (ES) recommends genetic testing in children with early-onset of obesity (<5 years) and hyperphagia. It is unclear whether these recommendations can also be used in adult obesity c...

Introduction: The impact of increased exposure to blue light (BL) from infancy over the past decade on growth and epiphyseal plate maturation is not well understood. This study aims to experimentally investigate the effects of BL exposure and duration during the prepubertal period on the epiphyseal plate.Materials and Methods: Eighteen female and eighteen male Sprague Dawley rats, aged 21-days postnatal, were divided int...

Introduction: The pubertal transition is accompanied by voice break in boys. Studies asking men to retrospectively recall their age at voice break report an average age of voice break corresponding to 13.4-14.0 years. However, it may be difficult to remember precisely when your voice broke, and recall bias is quite large. Little is known about voice frequency in boys and girls in relation to pubertal timing.Aim: To asses...

Background: The International Congenital Adrenal Hyperplasia (CAH) Registry provides rich longitudinal data from CAH patients with 21 Hydroxylase deficiency. We estimated the average total causal effect of fludrocortisone on blood pressure in patients with CAH by modelling within a causal inference framework.Methods: We constructed a directed acyclic graph (DAG) with domain experts (using Dagitty.net) to establi...

Background: Alterations in blood pressure in treated CAH due to 21 hydroxylase deficiency is contentious, with studies reporting different effects. We used data from young adults entered into the I-CAH registry to assess the change in blood pressure readings recorded within patients over time.Methods: We used longitudinal mixed effects modelling (LMEM) in R to account for repeated measures in two levels within patients a...

Introduction: IPEX Syndrome (Immune dysregulation, Polyendocrinopathy, Enteropathy, X-linked) is characterized by mutations in the Forkhead BoxP3 (FOXP3) transcription factor, leading to autoimmunity in various organs starting in the perinatal period. This syndrome manifests with proliferative lesions in the thyroid gland, gastrointestinal system, skin, and other organs. We report a case of a 4-month-old male with neonatal diabetes, resistant thrombocytopenia,...

Subclavian artery disruption sequence explains the development and association of Poland, Klippel-Feil, and Moebius anomalies with the hypothesis of vascular etiology. Herein, the coupling of Klippel-Feil-Poland-Moebius Syndromes and the diagnostic process in a patient who presented to our outpatient clinic with breast asymmetry will be discussed. At the age of 11 years and 10 months, the patient presented with breast asymmetry (smaller left breast-hypotelia). The patient&apos...

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=...

Introduction: Primary adrenal insufficiency (PAI) is a potentially life-threatening condition that requires appropriate diagnosis and treatment. The most common cause of PAI is congenital adrenal hyperplasia (CAH), but other well-established aetiologies include metabolic and autoimmune disorders, and physical damage. Mutations in more than 30 genes have now been associated with PAI, with considerable biochemical and phenotypic overlap. It is therefore importan...
