Introduction: Salivary androgens represent a non-invasive marker of puberty that may have utility in population studies as well as in the clinical arena.Objectives: To establish normal reference values of salivary androgens using LC-MS/MS and demonstrate the correlations between salivary androgens and pubertal development in boys.Methods: School-based adolescent cohort study with t...

Background: Short stature is a recognized complication of Crohn’s disease (CD) in children. Less is known on the impact of disease on final adult height and body proportions.Objective and hypotheses: To assess height and body proportions in 48 adults (F: 30; M: 18) with childhood (ACO) or adult (AAO) onset CD and 44 children (C) (F:22; M:22) with CD.Method: Standing, sitting height (SH) and leg length (SILL) were measured and ...

Introduction: The degree of consistency between the findings from next generation sequencing (NGS) and detailed endocrine assessment is unclear in boys with XY DSD.Objectives: Examine the range of endocrine and molecular genetic variation in boys undergoing evaluation for XYDSD.Methods: Boys with XYDSD who were evaluated in Glasgow from 2016 to 2018 were included. Sequence variants...

Introduction: Advances in diagnostic capability in the field of DSD hold great promise but need a regular review.Objectives: To study the range of endocrine and molecular genetic variation in a group of boys undergoing investigation for XY DSD.Methods: 157boys with median age of 0.9yrs (range,0,18) evaluated by the DSD Diagnostic Board in Glasgow from 2016to 2021 were included. Seq...

Background: Paediatric thyrotoxicosis is both rarer and more severe than in adulthood, rendering management difficult, and often unsatisfactory.Objective: To review outcome in a geographically defined area between 1989 and 2013; hence to develop an algorithm for improved clinical care.Method: Retrospective case note review plus questionnaire to family doctor requesting update. Graves’ disease (GD) was defined as positive TSH-R...

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...

Background: The pathophysiological mechanism of skeletal fragility in Duchenne Muscular Dystrophy (DMD) is unclear.Objective: To compare trabecular bone microarchitecture, cortical geometry, muscle area and fat fraction (FF) at distal femur and vertebral bone marrow adiposity (BMA) between DMD and controls.Method: Bone-muscle and muscle FF were assessed using 3T MRI and Dixon technique. BMA was assessed using 1H-MRS. Results expres...

Background: The pathophysiology of the increased fracture risk in Type 1 Diabetes Mellitus (T1DM) remains unclear.Objectives: Perform multimodality assessment to determine the effects of T1DM on bone health and fractures.Methods: Thirty-two children with T1DM at a median (range) age of 13.7 years (10.4, 16.7), and median HbA1c 65mmol/mol (27,100) were recruited. Serum bone alkaline phosphatase (BAP) and c-terminal telopeptide type ...

Background and aim: Metformin is widely used in Type 2 diabetes, with increasing reports of a potential bone protective role. We investigated the role of AMPK in mediating the effects of metformin on mesenchymal stem cell (MSC) differentiation to either osteoblasts or adipocytes.Methods: Confluent mouse MSCs (C3H10T1/2), wild type (WT) and AMPK knockout (KO) mouse embryo fibroblasts (MEFs) were treated with metformin(500 μM), AMPK-activator A769662(...

Background: An increasing need for non-invasive, out-patient based investigations has necessitated a re-evaluation of urinary gonadotrophins (uGn) for assessing puberty.Objective: Prospective evaluation of the relationship between first morning uGn measured by immunoassay and corrected for creatinine (uLH:uCr; uFSH:uCr), and basal serum gonadotropins (sLH, sFSH) and in response to LHRH stimulation test. Prospective evaluation of uGn trend in patients rec...
