Background: There are limited data available on the efficacy and safety of GH treatment in very young (<30 months) short children, born small for gestational age (SGA).Objectives: To determine the effect of 24 months of GH treatment on body height, BMI, and head growth as well as overall psychomotor development (using the Bayley Scale of Infant Development (BSID-II)) and demonstrate its safety in young (aged between 19 and 29 months) short SGA childr...

Females with Turner syndrome (TS) have a reduced life expectancy of about 13 years and a substantial excess mortality; about 50% of this is the result of cardiovascular pathology. Hypertension affects 20-60% of females with TS and is the single most modifiable risk factor for cardiovascular disease. However, hypertension in TS is both under-diagnosed and under-treated. The presentation details a practical approach to monitoring blood pressure and managing hypertension in TS. T...

Background: Patients with hyperinsulinism (HI) and anterior hypopituitarism often present in the new-born period (NBP). However up to 30% patients with HI and an unknown number with hypo-pit will present in the first year of life. Despite advances in care the long-term neurological outcome for patients with HI is poor in 20-40% cases.Aim: To retrospectively evaluate the care given during the NBP in a series of patients diagnosed with late presenting pote...

Background: Fertility Preservation (FP) in children and adolescents poses unique challenges as efficacy is unproven.Objective and hypotheses: To describe characteristics and evidence for potential fertility in ovarian and testicular tissue cryopreservation specimens (OTCP and TTCP respectively) taken from paediatric and adolescent patients, stratified by age, and prior chemotherapy.Method: Retrospective review of gonadal biopsies a...

Introduction: Focal disease of the pancreas causing hyperinsulinism (FHI) has 2 essential characteristics 1) the inheritance of a paternally derived mutation in ABCC8 or KCNJ11 in conjunction with loss of a region of the maternal chromosome 11p13.1 and 2) the ability to be cured by resection of the focal lesion while sparing the majority of the pancreas. At the time of surgery the surgeon resects the focal lesion until clear margins are avail...

Background: First line treatment for thyrotoxicosis is thionamide (TA) antithyroid drug therapy. The TA used is usually Carbimazole in the UK. TA can be administered in a relatively large 'blocking' dose that prevents endogenous thyroid hormone synthesis, requiring thyroid hormone replacement (block and replace or BR), or in a smaller dose that renders the patient euthyroid (dose titration or DT). The American Thyroid Association (ATA) recommends DT be...

Background: Links between early life exposures and long-term health outcomes may in part be due to nutritional programming, and suggested benefits of breast feeding during infancy include reduced risk of obesity and metabolic disease. Mechanisms remain unexplained but potential differences in lipid exposures during infancy may be involved.Objective and hypotheses: To explore the effects of breast- or formula-feeding on lipidomic profiles we used recently...

Introduction: 6 Mercaptopurine (6MP) is a cornerstone of maintenance therapy in pediatric acute lymphoblastic leukemia (ALL). Fasting hypoglycemia is a rare side effect of 6MP therapy that has been observed in children being treated for ALL. We present two pediatric patients who developed symptomatic, fasting hypoglycemia during maintenance therapy.Case Description: A 7-year-old male with standard risk B ALL receiving ma...

Background: DICER1 is a member of the Ribonuclease III family that plays a crucial role in the biogenesis and the maturation of microRNAs. Pathogenic germline DICER1 variants cause a hereditary cancer predisposition syndrome with a variety of manifestations: in addition to first described pleuropulmonary blastoma (PPB) and ovarian sex cord-stromal tumours, individuals may also develop benign (multinodular goiter MNG, cystic nephroma\.) or malignant tumours as differen...

Background: Monitoring treatment of children with classic congenital adrenal hyperplasia (CAH) is difficult and biochemical targets are not well defined.Objective and hypotheses: To analyse the urinary steroid metabolome of children with classic 21-hydroxylase deficiency (21-OHD) during treatment with hydrocortisone and fludrocortisone.Method: We retrospectively analysed 553 daily urinary steroid hormone metabolite profiles determi...
