Background: The efficacy of growth hormone (GH) treatment in short, healthy children diagnosed with growth hormone deficiency (GHD) or those meeting the criteria of idiopathic short stature (ISS) suggest that an overlap exists between these two conditions. Although flawed and inconsistent, growth hormone stimulation tests (GHST) are the key diagnostic tool differentiating between GHD and ISS affecting clinical decisions such as treatment eligibility and dose.<...

Context: Pregnancy and parturition involve a complex interplay between maternal health and that of her offspring. Graves’ disease and its management have been associated with adverse pregnancy, labor and delivery, as well as neonatal outcomes. Adaptation of the hypothalamic-pituitary-thyroid axis can be reflected by measuring thyroid function levels in newborn screening (NBS).Objective: To investigate the character...

Background and aims: Disparities in children's height often reflect socio-economic inequalities. Our aims were: (A) to describe anthropometric and socio-demographic data of children with short stature (CDC based height-z score<-2SDS) at age 6-7 years, compared to peers with height-z score≥-2SDS. (B) To assess risk factors for short stature at age 6-7 years based on growth and socio-demographic data at age 0-2 years.Met...

Objective: Craniopharyngiomas, diagnosed and treated during childhood, pose significant challenges due to their location in the sella turcica, adjacent to the pituitary and hypothalamus. Patients often experience endocrine deficiencies which may affect their body composition and metabolic health. We aim ed to explore the body composition components and their interaction with metabolic syndrome components in pediatric patients with craniopharyngioma following n...

Background: Irisin is a myokine involved in the browning of adipocytes, regulation of body composition, and enhancement of glycemic control. Additionally, irisin has been suggested to play a role in the signaling mechanisms associated with activation of the hypothalamic-pituitary-gonadal axis and the onset of puberty. Given the reported relationship between irisin levels and glycemic control, as well as the link between body composition and glycemic control, w...

Aim of the Study: Cryptorchidism occurs more frequently in CF-children, and malformed epididymis was found more in cryptorchid boys with abrogated mini-puberty. Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) is transporter protein that acts as a chloride channel. Specifically, CFTR is associated with spermatogenesis and fertility.Patients and Methods: Testicular biopsies for histological and RNA analysis from...

Introduction: Propionic Acidaemia (PA), an organic acidaemia, is characterized by episodes of decompensation with severe metabolic acidosis and hyperammonaemia. PA is associated with low bone mineral density and osteoporosis. Hypocalcaemia is known to occur in 35-65% of decompensations, however the underlying pathophysiology remains unclear. PTH resistance has previously only been described in one case of hypocalcaemia in PA and we report the first use of ...

Background: Pseudohypoparathyroidism type 1b (PHP1b) is caused by epigenetic errors on the maternal GNAS allele at differentially methylated regions (DMRs) associated with exons A/B, XL, and NESP that lead to reduced production of Gαs transcripts most notably in the renal proximal tubule and thyroid follicular cells. Most PHP1b cases appear sporadically, few of which can be explained by paternal uniparental disomy involving chromosome 20q, leading to global methy...

Background: Graves’ disease therapy in young children may be challenging due to lack of therapy options. The safety of Radioiodine Ablation (RIA) has not been proven in children under age of 10 years. Propylthioracil (PTU) therapy has been linked to hepatic failure and became contraindicated in pediatrics.The case: A 6-year-old female was diagnosed with Graves ‘disease and treated with Methimazole (MTZ) and Propranolol. A few days after startin...

Introduction: Most testis expressed (TEX) genes are testis-specific and evolutionarily conserved and several studies have reported important roles of TEX11, TEX12, TEX14, TEX15 and TEX 101 in mammalian fertility. Retrotransposons are thought to be critical for the evolution of mammalian genomes. TEX19 functions in the post-translational regulation of L1 retrotransposons, which are involved in maintaining trans-generational genome stability. In boys with crypto...
