Aims: The lowest licensed dose of tolvaptan for treatment of hyponatraemia is 15 mg. There is little data on lower doses. Our study aimed to evaluate the safety of an initial dose of 7.5 mg tolvaptan.Methods: We retrospectively reviewed data from a London teaching hospital over a 6-year period. All adults administered a first dose of 7.5 mg tolvaptan were included. Three different timeframes were reviewed: 4-12, 12-18 and 18-30 hours. We analysed respons...

Background: Testosterone replacement therapy (TRT) is widely used for the treatment of symptomatic hypogonadism in men. However, data on prescription behaviours of TRT are limited. The objective of this study was to investigate clinical characteristics associated with the likelihood of being prescribed TRT by general practitioners (GPs) in North West London (NWL).Methods: We carried out a retrospective cohort study using Discover database of GP-registere...

Introduction: Obese adults of South Asian origin in the UK are considered to be obese at a BMI of 27.5 kg/M2 compared with 30 kg/m2 for other groups and are at increased risk of obesity related disorders such as type 2 diabetes. From July 2021, GPs have been offered financial incentives for referral of adults to weight management services. However no provision or adjustments have been made for children and young people especially those of South Asian orig...

Introduction: The uterus develops during puberty and increases not only in length but also in width and depth, to achieve a mature shape. Pubertal induction with exogenous oestradiol aims to mimic this. Research to date shows variable results for the attainment of an adult uterine configuration in females with hypogonadism. Suboptimal uterine development is hypothesised to be a contributing factor for adverse reproductive outcomes in females with hypogonadism undergoing egg do...

Introduction: We sought to the impact of an out of hours telephone advice service for children and young people with diabetes mellitus on Emergency Department attendance rates.Methods: In July 2014 we commenced a collaborative service for 240 patients with diabetes across two Paediatric diabetes centres- Croydon University Hospital (CUH) and St George’s University Hospital, London. Paediatric diabetes specialist nurses and consultants in Paediatric ...

Introduction: Several studies have described ethnic differences in HbA1c. Non-Caucasian patients have been found to have a higher HbA1c than the Caucasian ones. These differences have often been attributed to disparities in access to medical care or quality of the care. However differences in HbA1C in ethnic minorities could also relate to biological factors so we looked at mean levels of glycaemia. The aim of our study was to observe if there is a similar correlation between ...

Traditional literature agrees that Diabetic Ketoacidosis is typically associated with Type 1 Diabetes Mellitus, but can be associated with stress including infections in Type 2 diabetics. The authors did a restrospective evaluation of diabetic ketoacidosis presenting to a large district hospital in London. 343 patients were admitted with diagnosis of Diabetic Ketoacidosis during the COVID peaks from January 2020 to January 2021. 57% of these were Type 1 diabetics and 43% were ...

Background: Studies suggest that glucocorticoid hypersecretion alongside primary hyperaldosteronism (PA) is common and may contribute to the adverse metabolic phenotype. Adrenal crisis post-surgery for PA is rare.Aim: To determine the prevalence of cortisol co-secretion in PA in patients at Imperial College London NHS Trust, Hammersmith Hospital (a tertiary referral centre for adrenal tumours).Methods: Am...

Background: Characterisation of large adrenal lesion is challenging. There is no single robust imaging marker in defining benignity, especially for lesions which are greater than 4cm and are believed to carry increased risk of malignancy.A radiolabelled cholesterol analog tracer, I-131-Norcholesterol (NP-59), localises to adrenal cortical lesions. It has an established role in Conn’s syndrome. It is not expected to concent...

Background: Phaeochromocytomas (PCC) and paragangliomas (PGL) are tumours derived from neural crest cells within the adrenal medulla or extra-adrenal ganglia, respectively. Over 20 known genes are implicated in at least 30% of cases. Experience with these tumours in individual centres is limited due to their rarity.Objective: To describe the demographics, genetics, treatment and progression-free survival (PFS) in ...
