Background: We are not aware of other longitudinal cohort studies of boys with prepubertal assessment of exposure to endocrine-disrupting chemicals (EDCs) and annual long term follow-up of growth and puberty to evaluate semen quality.Objective: To describe semen quality and explore associations of prepubertal serum concentrations of organochlorine compounds and pubertal measures with semen parameters in an ongoing longitudinal cohort study of Russian boy...

Purpose: To investigate the overall prevalence of vertebral fractures (VF) following childhood acute lymphoblastic leukemia (ALL) treatment and examine the association of VF with growth trajectory and insulin-like growth factorsMethods: Children (n = 172; 59.3 % male) diagnosed with ALL at age between 2 and 18 years were assessed for VF by screening the lateral thoracolumbar spine radiographs (Genant’s semi-quantitative met...

Introduction: Hypospadias is often associated with reduced testosterone synthesis or action. High rates of complications are reported with surgical repair of hypospadias, including wound dehiscence. Boys with hypospadias have previously been demonstrated to have increased reactive oxygen species (ROS) compared to healthy controls and there is a known link between male hypogonadism and oxidative stress. It is not clear what effect ROS has on wound healing in bo...

Introduction: The annual incidence of severe influenza infections reaches 5 million cases globally. Patients with diabetes mellitus (DM) are known to suffer more severe influenza infections, with increased mortality. Despite vaccination being recommended as standard of care, vaccination uptake rates have remained low for our DM patients. We undertook a quality improvement (QI) initiative to improve influenza vaccination uptake rates in our paediatric DM clinic...

Background: Aluetta® Smartdot™ (Merck Healthcare KGaA, Darmstadt, Germany) is a novel injection device for administering recombinant-human growth hormone (r-hGH), integrated with a smart knob attachment for data transmission that combines ease of use with advanced capabilities. Integration with Growzen™ digital ecosystem empowers healthcare professionals (HCPs) with remote monitoring of patient adherence, thereby promoting optimal cl...

Introduction: Our study aimed to describe the clinical profile of children with central precocious puberty (CPP) presenting to a single tertiary centre, and to determine the factors that would lead patients and families to pursue treatment with gonadotrophin releasing hormone (GnRH) agonist as well as the predictors of a more favourable final adult height in this cohort.Methods: We conducted a retrospective medical chart...

Introduction: Estrogen treatment can be used for pediatric patients with Marfan syndrome who wish to control the rate of excessive height growth. However, the appropriate timing of treatment initiation is controversial and studies were limited. In this study, the authors aimed to find out when the initiation of estradiol therapy is most appropriate for controlling height growth rate in patients with Marfan syndrome.Methods:</stro...

GX-H9 is a long-acting form of recombinant human GH under clinical development for both adults and children with GH deficiency (GHD). This study was designed to compare 12-month effects of once-weekly and twice-monthly (every other week; EOW) administration of GX-H9 treatment to that of Genotropin®, in pediatric patients with GHD. A randomized, open-label, active-controlled, parallel study was conducted at 27 endocrinology centers in 10 countries (Europe and Ko...

Background: The presentation of early-onset Primary Ovarian Insufficiency (EO-POI), most often with primary amenorrhea, is at one end of a spectrum spanning 40 years. The aetiology of POI is frequently unclear but next generation sequencing of varied age groups has identified several associated genetic variants. Whether girls with EO-POI are more likely to have a genetic aetiology than those with later presentations remains unknown.<stro...

Background: The need to understand the relationship between bone, muscle, and fat within the bone-muscle unit has recently gained great prominence. Although high resolution (HR) MRI is a non-invasive imaging modality that can provide this information, there is limited expertise in children and young people.Objectives: To establish MRI-based normative data for bone, bone marrow adiposity and muscle adiposity in children a...
