IGF-I and -II influence cytotrophoblast proliferation by activating the type-I IGF receptor (IGF1R) in first trimester human placenta. Ligand access to receptors is regulated by IGF binding proteins (IGFBPs) 1-6. In humans, the most abundant IGFBPs at the maternal-fetal interface are IGFBP-1 and IGFBP-3; we hypothesised that these IGFBPs function to regulate the effects of IGFs in the placenta and used our placental explant model, in which proliferation and differentiation are...

ObjectivesTo compare our practice, at Sunderland Royal Hospital, to the recommendations of NIH Consensus Development Programme (February 2002) and BAES.MethodRetrospective audit of patients who had adrenal mass on imaging studies done between 1996–2004.Patients who had incidentally detected adrenal mass were included. Patients with symptoms and / or signs suggesting adrenal mass pr...

ObjectiveThyroid replacement therapy needs careful titration, and recently there has been discussion regarding the bioavailability of different thyroxine preparations [1]We have taken the opportunity of comparing thyroid function in 18 females who were enrolled in a trial studying the effects of thyroxine therapy on subclinical hypothyroidism [SCH].MethodsThese patients (at entry to tri...

Background: 50% of patients with osteogenesis imperfecta (OI) will have dental involvement of some degree including dentinogenesis imperfecta and a severe malocclusion. OI is the most common inherited disorder of bone fragility in children, increasing fracture risk 100-fold.Aim: To assess the utilisation of tertiary dental services by children and young people with OI attending a supra-regional multidisciplinary OI service and review of the pathology ide...

Introduction: Nephrogenic diabetes insipidus is caused by a deficiency in the action of anti-diuretic hormone, and can be life threatening if not treated appropriately. Lithium is a commonly used mood stabiliser in psychiatry and is known to cause NDI in around 12% of patients. It has been reported in the literature that severe hyperglycemic state may trigger symptomatic lithium-induced NDI in patients who had been on prolonged lithium therapy.Case: We r...

Introduction: Differences/Disorders in Sex Development (DSD) represent a diverse range of conditions that present at various stages of life. A multidisciplinary team (MDT) approach is required to reach a specific diagnosis and management plan, but few large single centre studies of the range and prevalence of diagnoses have been undertaken.Method: Medical records of all children with DSD discussed at a single MDT between 1-Jan-1996 and 31-Dec-2015 (n...

Thyrotoxic periodic paralysis (TPP) is a rare endocrine emergency where early diagnosis of both hypokalaemia and thyrotoxicosis are vital to allow prompt treatment to prevent life-threatening complications and prevent recurrences. We present the first reported case of TPP in which four known stimulants of Na–K–ATPase acted simultaneously to produce profound hypokalaemia. A 32 year-old competitive body-builder took thyroxine supplements & a long-acting β2 ago...

Introduction: Hyponatremia from SIADH secondary to undiagnosed Myelomas are extremely rare and we present one such case.Clinical case: 63 year old woman with background of MGUS under regular haematology review/ILD/NAFLD/IHD presented with severe constipation on top of weakness, weight loss and tingling in the peripheral extremities. She was euvolemic on admission with Serum Sodium 124mmol/l, Potassium 4.3 mmol/l, Urea 3....

Introduction: The International Society for Paediatric and Adolescent Diabetes (ISPAD) 2022 Nutritional Guidelines recommend calculating carbohydrate requirements using an indivualised equation, such as the Schofield equation. Up to 2023, our centre used the Scientific Advisory Committee on Nutrition (SACN) 2011 guidelines that only require age to determine average carbohydrate requirements. The latest National Paediatric Diabetes Audit (NPDA) showed our centr...

Introduction: Incompletely controlled acromegaly has a three-fold excess all-cause mortality, with stroke being the predominant cause of death. Debate exists about the relationship between fractionated radiation (FRT) and risk of stroke, with radiation damage to cerebral vasculature potentially being a cause. We present outcomes in patients treated by gamma knife STRS at the National Centre for Stereotactic Radiosurgery in Sheffield, with...
