Background: In-vivo skeletal MRI imaging remains challenging due to the extremely short MR relaxation times (<1 ms) of protons bound to water in bone. However, each MRI sequence contains properties identifiable through feature-based recognition, highlighting characteristics relating to skeletal configuration. We thus present a novel statistical method for clinical 1.5 Tesla (T) MRI in quantifying trabecular microstructure and use HRpQCT to determine its accuracy.<...

Introduction: Anti-obesity drugs with increased efficacy and safety are urgently being sought. Peptide YY3–36 (PYY3–36) is an attractive drug target due to its anorectic effect and decreased circulation concentration, without drug resistance, in obese individuals. Its short half-life and required method of delivery are limiting factors in its clinical application. Transport and uptake mechanisms, including blood-brain barrier passage, of vitamin B12 (B12) is highly e...

Background: Children with ISS have an array of causes that lead to short stature and/or poor growth velocity. Genetic causes of short stature, notably SHOX mutations, can be associated with subtle skeletal disproportion with shorter limbs, manifesting as increased sitting-to-standing height ratios or SDS.Objective and hypothesis: Children with ISS and skeletal disproportions have a diminished growth response to GH treatment compared to chi...

Background: In the vast majority of cases, achondroplasia and hypochondroplasia are attributable to hotspot missense mutations in the FGFR3 gene. 96% of patients have a G(1138)A and 3% have a G(1138)C point mutation. We report on a family whose members have a deep intronic mutation that leads to a novel cryptic splicing variant of the FGFR3 gene, and via this pathway results in new pathogenicity manifesting as achondroplasia.Case...

Handling diabetes at a very early age is difficult, even more when a complementary diet has not yet started. There is increasing evidence supporting the use of CSII in infants but some tricks could be useful.Infant 1: 10 mo, admitted in cardiac arrest. ROSC after 3 minutes, severe DKA (pH 6,95). Transferred to PICU, received also plasma transfusions. Day 2: CGM Dexcom G6 was started and tests for pancreatic autoimmunity and genetic of ne...

Objective: Hysterosalpingography (HSG) to assess patency of the Fallopian tubes with the use of iodinated (oil- or water-based) contrast media is a standard test during fertility work-up. An observational study found an increased risk of congenital hypothyroidism in neonates whose mothers were exposed to high amounts of oil-based contrast during HSG. Oil-based contrast contains more iodine (480mg Iodine/ml) than water-based contrast (250mg Iodine/ml). We inves...

Background: Hypospadias in boys may be associated with a lack of androgen exposure during the masculinisation programming window. As testosterone has effects on the vasculature, we assessed whether boys with hypospadias show any evidence of vascular dysfunction.Methods: Excess foreskin tissue was obtained from boys undergoing hypospadias repair (cases) or circumcision (controls) and small arteries dissected from this tissue. Vascular contractility was as...

Introduction: Hypogonadotropic hypogonadism (HH) is a rare condition, where a definitive diagnosis is often hard to reach.Objectives: To describe the clinical, biochemical and genetic findings in cases with suspected HH in the West of Scotland who were referred for genetic analysis between 2016 and 2020.Methods: Information was collected on clinical assessment including family hist...

Background: Hypogonadism has been associated with cardiovascular disease. However, little is known about the cardiovascular impact of hypogonadism during development. Using hypospadias as a surrogate of hypogonadism, we investigated whether hypospadias is associated with vascular dysfunction during childhood and whether it is a risk factor for adult cardiovascular disease.Methods: Our human study spanned molecular mechan...

Introduction: Gonadectomy may be indicated in people with differences or disorders of sex development (DSD). Based on historical data from the International-DSD (I-DSD) Registry that showed considerable practice variation, this I-DSD care quality improvement project seeks to determine, through prospective surveillance, the frequency of gonadectomy in individuals with DSD internationally.Methods: All existing I-DSD centre...
