Introduction: Deranged Mitochondrial bioenergetics is a key feature of type 2 diabetes and obesity but its status in non-obese type 2 diabetes patients is not known. The aim of the present study was to assess the status of mitochondrial oxidative phosphorylation and ROS metabolism in subcutaneous adipose tissue isolated from 4 groups of subjects: non-obese subjects with type 2 diabetes (NOT2D), non-obese non diabetic (C), obese non-diabetic (OB) and obese type 2 diabetes subje...

A 48-year-old woman presented to her GP with polyuria and proximal muscle weakness. She was found to have newly developed hypertension at 180/96 and her serum potassium was 2.7 mmol/l. Lisinopril 40 mg od and Slow-K 1 tablet bd were started and she was referred for further investigation.On clinic review blood pressure was 188/110 supine and 190/110 standing. Serum sodium was 147 mmol/l, potassium 3.7 mmol/l and total bicarbonate 29 mmol/l. Her Lisinopril...

TSH-secreting pituitary adenomas are rare and the optimal investigation and management is uncertain.A 42-year-old lady presented with a three-month history of three stone weight loss, palpitations, heat intolerance and tremor. Her sister was being treated for Graves’ disease. Visual fields were intact.Thyroid function tests showed free T4 concentration 29.5 pmol/l (9.0–19.0) and TSH concentration 3.672 mU/l (0....

Two patients presented to us with polyuria and polydipsia.Case 1– A 34 year old gentleman was referred with polyuria, polydipsia, diffuse headaches and poor sleep. Initial plasma and urine osmolality were 306 and 272 milliosmol/kg respectively. Water deprivation test demonstrated normal concentrating ability. Starting urinary osmolality was 788 milliosmol/kg, rising to 877 milliosmol/kg. MRI pituitary was normal. Hypertonic saline infusion test prod...

Arachidonic acid (AA) metabolites derived from cytochrome P450 enzymes regulate vascular tone and renal tubular function. The cytochrome P450 4A (Cyp4A) enzymes are responsible for the synthesis of 20- hydroxyeicosatetraenoic (20-HETE), the most abundantly produced AA Cyp P450 metabolite in the kidney. Cyp4a expression and the production of 20-HETE, have been implicated in the development of hypertension. Here we have investigated the expression of various renal isoforms of Cy...

Anabolic steroids enhance performance in atheletes, but can lead to life threatening consequences. We report a 33-year-old male amateur body-builder using anabolic steroids, presenting with acute inferolateral myocardial infraction and marked hyperlipidaemia. He had no known cardiovascular risk factors. Despite rapid thrombolysis, peak creatinine kinase was 3,348 iu/l, signifying significant myocardial damage and a markedly raised total cholesterol of 10.6 mmol/l, with a low H...

Carcinoid tumours are the most common neuroendocrine tumors with an estimated incidence of 7-13/ million population. The clinical symptoms of carcinoid tumours usually relate to presence of the carcinoid syndrome, local symptoms or metastases. Most are asymptomatic with only 10% manifesting the 'carcinoid syndrome'. We report an 86 year-old lady referred for evaluation of multiple subcutaneous, nodules around her neck and upper back, with a suspicion of underlying lymphoprolif...

Background: Patient Safety Noticed issued by Welsh Government in June 2021 set out multiple action plans to be implemented by Welsh health boards to improve recognition and management of adrenal crisis. Hospitals were advised to review policies to ensure all patients at risk of Adrenal Crisis [(primary/secondary/tertiary adrenal insufficiency (AI)] were identified.Aim: In response, our hospital commenced a quality improv...

Background: Carbimazole is a commonly used and effective treatment for hyperthyroidism. Although on the World Health Organisation’s list of essential medicines, it comes with the potentially significant side effect of agranulocytosis. We set out a Quality Improvement Project to improve communication with patients to ensure their understanding through creating a patient information leaflet.Methods: 30 patients receiv...
