Background: Radioactive iodine therapy (RAI) is established as a safe and effective treatment for adults with Grave’s disease. As thyrotoxicosis in children is rare, it is difficult to obtain high quality evidence about the safety and efficacy of RAI. We present data from our centre between 2007 and 2017.Methods: 20 paediatric patients with hyperthyroidism (16F), median age 15.7 years (range 10.8–19.3) had RAI in our centre either one or two do...

Background: Patients being treated for differentiated thyroid cancer (DTC) receive a dose of Radioiodine for remnant ablation. Occasional patients appear to have little or no iodine uptake at all in the thyroid bed or else where even shortly after thyroidectomy.Objective: To evaluate the influence of ‘Coexisting Thyroiditis’ on radioiodine uptake in thyroid cancer ablation doses.Methods and Design: Retrospec...

Case history: A previously well 45-year-old lady presented with a 3-year history of hypertension initially diagnosed at a routine health check. Her blood pressure (BP) was 170-180/90-100 mmHg.Investigations: Showed hypokalaemia (K+= 3 mmol/l; NR 3.5-5.3 mmol/l), raised aldosterone (976pmol/l; NR 100-500pmol/l) and supressed renin activity (<0.2nmol/l/h), meeting criteria for diagnosing primary aldosteronism (PA). CT adrenals showed a 2.5 cm left adre...

A 65-year-old Afro-Caribbean gentleman, with a >10-year history of hypertension, frequently recorded blood pressures of >160/80 mmHg. His serum electrolytes showed Na+ 145 mmol/l and K+ 3.2 mmol/l. MRI demonstrated 13 mm left medial-limb adrenal adenoma. His hypertension was uncontrolled on treatment with amlodipine 10 mg OD, spironolactone 50 mg OD, losartan100 mg OD and doxazosin 16 mg OD. Although his quality of life was reduced, and he dislike...

Introduction: Patients with the familial cancer syndrome von Hippel–Lindau disease (VHL) are enrolled in radiological screening programmes which aim to identify tumour development at an early stage. This facilitates timely intervention to lesions when the risk of metastatic spread is low and when they are conducive to less-invasive and parenchymal-sparing interventions, thereby minimising treatment-related morbidity. A number of international screening protocols exist, al...

Introduction: Germline mutations in succinate dehydrogenase subunit B (SDHB) are one of the commonest findings in familial paraganglioma (PGL) syndromes and account for one quarter of PGLs associated with germline mutations. Although the penetrance is low, the malignancy conversion is high; up to 30%. With the increasing availability of genetic testing and the identification of ‘asymptomatic carriers’ of the SDHB gene mutation, it is therefore impor...

Introduction: Phaeochromocytoma localisation is generally reliably achieved with modern imaging techniques, particularly in sporadic cases. Diagnostic doubt can arise due to the presence of bilateral adrenal abnormalities, particularly in patients with mutations in genes predisposing them to the phaeochromocytoma development. In such cases, surgical intervention is ideally limited to large or functional lesions due to the long-term consequences associated with hypoadrenalism. ...

Introduction: The provision of out-of-hours (OOH) care for hospital inpatients is currently a hot political topic with aspirations for ‘seven day working’ and earlier specialist involvement. Care for patients with diabetes or endocrine problems OOH (which accounts for 75% of each week) is variable and often falls as a default to the general medical team. Our centre (over 1000 beds, all major specialities) has, for many years, provided a 24/7 service for GPs and hospi...

Primary aldosteronism (PA) is an important cause of hypertension which confers significant cardiometabolic risk. In approximately half of cases, the cause is a surgically resectable unilateral aldosterone-producing adrenal adenoma, making PA the most common potentially curable form of hypertension. Despite this, long-term data on surgical outcomes that could be used to guide discussions with patients are sparse. Here, we report on clinical outcomes several years post-adrenalec...
