Background: Inherited forms of congenital hypothyroidism (CH) account for approximately one quarter of all causes of CH. These include biosynthetic defects and developmental and morphological abnormalities.Objective: Describe the Scottish experience of genetic testing in CH.Method: Retrospective study over 37 years up to March 2016. Patients were selected on the basis of imaging findings or strong family history of CH.<p class=...

Introduction/Aim: Children with Prader-Willi syndrome (PWS) show alterations in infantile, childhood and pubertal growth. Growth Hormone (GH) therapy is recommended due to reported improvements in height velocity (HV) and body composition. The aim was to describe the patterns of growth in PWS and the influence of both changes in clinical practice and GH therapy.Methods: Height SDS (HSDS), BMISDS and HVSDS of children attending a dedicated PWS clinic, 200...

Background: Individuals with Down Syndrome are at an increased risk of developing thyroid disease. Given that thyroid disorders represent a preventable cause of neurodevelopmental impairment, early detection and treatment are essential to maximise cognitive abilities in this already impaired population. This service evaluation sought to assess the efficacy of the Down Syndrome Hypothyroid Screening programme in its uptake and subsequent diagnosis of hypothyroi...

Background: Hypoglycaemia is one of the most common presenting complaints at paediatric emergency department. There are many distinct causes of hypoglycaemia, ranging from nutritional insufficiency, infectious origins, to metabolic disorders. A thorough investigation can help differentiate the cause of hypoglycaemia, with subsequent tailored management. All patients with hypoglycaemia should have a full clinical assessment and together with a hypoglycaemia scr...

Background: The recommended capillary TSH cut-off level for neonatal screening for congenital hypothyroidism (CH) in the UK is 10 mIU/l. However several of the regional screening laboratories have adopted lower cut-off limits in order to increase detection sensitivity. There is now pressure to standardise the UK screening programme with universal adoption of the recommended cut-off. Scotland has been using a cut-off of 8 mIU/l since the adoption of AutoDELFIA TSH screening met...

Background: Autoimmune thyroid disease (AITD) is the most common thyroid disorder in the paediatric age range. However, the development of thyroid dysfunction in biochemically euthyroid children with positive TPOAbs and associated risk factors is unclear.Objective and hypotheses: To evaluate the evolution of children with positive TPOAbs and normal thyroid function and identify predictive factors for the development of thyroid dysfunction.<p class="a...

Endochondral bone formation regulates bone growth both during embryonic development and after birth. Several different autocrine/paracrine or hormonal mechanisms govern the regulation of endochondral bone formation. Among those is the pathway involving stimulatory G protein, which primarily mediates the actions of parathyroid hormone-related peptide (PTHrP) in the growth plate. PTHrP is synthesized in the perichondrial cells and chondrocytes at the end of bones. In the growing...

Background: Over 800 different mutations in GCK gene have been reported in the Human Gene Mutation Database, the vast majority of which result in monogenic diabetes (Maturity Onset Diabetes of the Young, MODY type 2). The missense mutation p.Leu122Val is listed in that database as "disease-causing". However, the National Center for Biotechnology Information ClinVar database (Variation ID 585919) reports that this mutation is of "uncertain ...

Background: Autoimmune thyroid diseases are multifactorial diseases with a genetic susceptibility and environmental factors. A potential role of the protein tyrosine phosphatase non-receptor type 22 (PTPN22) gene, the interferon induced helicase domain 1 (IFIH1) gene, the TSH receptor (TSH-R) gene polymorphisms on autoimmune thyroid diseases (AITDs) in children has not been established equivocally yet.Objective and hypotheses: To estimate the association...

Background: X-linked hypophosphatemia (XLH) is a rare, often debilitating genetic disorder caused by mutations in the phosphate-regulating gene with homologies to endopeptidases on the X chromosome (PHEX) that is characterized by excess fibroblast growth factor 23 (FGF23), hypophosphatemia, skeletal deformities, and growth impairment.1,2 Conventional therapy with the combination of phosphate and active vitamin D is associated with poor treatment adh...
