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: Adamantinomatous craniopharyngioma (aPCs) are complex intracranial neoplasms that arise in the sellar or parasellar region affecting the endocrine system, leading to severe comorbidities. Activating mutations resulting in degradation resistant b-Catenin have been shown to be the main driver for a large proportion of these neoplasms. However, the underlying genetic driver for a number of these tumours remains unknown. Here, using murine transgenic...

Background: Visual impairment is a critical component of aftercare in survivors of childhood onset craniopharyngioma (CP). This study aims to evaluate retinal ganglion cell complex thickness (GCC) and correlation with clinical parameters in patients with CP using optical coherence tomography (OCT).Methods: Sixty eyes of 37 patients with childhood onset craniopharyngioma and 90 eyes of 45 age and sex-matched healthy volun...

Introduction: Ectopic posterior pituitary (EPP) is a neuroimaging diagnosis frequently identified together with other hypothalamo-pituitary (H-P) abnormalities [hypoplastic anterior pituitary and thin interrupted stalk -Pituitary Stalk Interruption Syndrome (PSIS)] and associated with variable endocrine phenotypes evolving over time. We aim to describe the spectrum of hormonal deficiencies and neuroimaging abnormalities in a large cohort of children with EPP.<...

Background: Clinical use of serum gonadotropins (Gn) test for diagnosis of pubertal disorders is always limited by invasive sampling, requirement of hospital visit, high expense and the feature of pulsatile secretion of Gn. As an alternative, evaluating first morning voided (FMV) urinary Gn (U-Gn) may facilitate non-invasive pubertal assessment.Objective: In this study, we will explore whether FMV U-Gn can predict the ac...

Background: Presence of current acne is well described in adolescents and adults with altered sex steroid levels, e.g., in polycystic ovarian syndrome, androgen producing tumors and misuse of anabolic androgenic substances. However, less is known about the impact of physiological concentrations of testosterone and dihydrotestosterone (DHT) quantified by gold standard LC-MS/MS methodologies on the development of acne in healthy adolescent boys and girls.<p ...
