Severe hyperkalemia post adrenalectomy is documented in the literature but not actively sought after in high risk post-operative patients.Case: Fifty-one year old woman with a 12 year history of hypertension and hypokalemia. Her BP was controlled with amlodipine 10 mg OD. Serum aldosterone was 2832 pmol/l with undetectable renin activity leading to aldosterone to renin ratio (ARR) >28 000 pmol/l per ng/ml per h. Creatinine was 75 μmol/l with eGF...

Objective: There is currently extensive debate regarding elevated TSH (Thyroid Stimulating Hormone) concentrations and associated cardiovascular risk. This study investigated whether correlations exists between TSH concentrations within the accepted range of normality and increasing cardiovascular risk.Design: We performed a cross-sectional study of 728 asymptomatic women aged 45–60 years attending for thyroid screening over a twelve month period. P...

A 59 year old man was admitted with epistaxis. Blood pressure on admission was 213/110 mmHg. Past medical history included hypertension (3 years) and a cerebrovascular accident 5 years previously. Drug therapy included an ACE inhibitor, beta-blocker and thiazide diuretic. He denied thirst, polyuria or weight loss. He was an ex-smoker. On examination he was not Cushingoid. There were no diabetic complications.On block analysis potassium was 2.2mmol/l and ...

Introduction: Type 1 diabetes is an autoimmune condition resulting in insulin deficiency. Surveillance of other autoimmune disorders such as coeliac disease and hypothyroidism is common practice due to their higher co association. We describe a case of a 14 year old girl with 2 rarer autoimmune conditions; primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD)Case summary: A 14 year old girl presented ...

Background: Extrapulmonary PD NECs carry a poor prognosis. Some studies suggest cisplatin is more appropriate for younger patients due to its increased potency and nephrotoxicity compared to carboplatin, but randomized trials are lacking. We aim to determine whether there is a difference in outcomes for cisplatin vs carboplatin while adjusting for possible confounding factors.Methods: We identified PD NEC patients at Mayo Clinic between 2000-2022. Kaplan...

Background: Addison’s disease (AD) in both humans and dogs is characterised by corticosteroid deficiency requiring lifelong hormone therapy. In humans autoimmune pathogenesis is established; at diagnosis ~90% of patients are 21-hydroxylase (21-OH) autoantibody positive, with antibodies to other adrenal antigens also detected. The pathogenesis of canine AD is less well characterised; autoimmune mechanisms are suspected, with anti-adrenal autoantibodies demonstrated by indi...

IntroductionInsulin-like growth factors-I (IGF-I) and -II (IGF-II) are important in regulation of metabolism and growth. We previously reported in normal weight normoglycaemic individuals that low circulating IGF-II predicts future weight gain. We subsequently investigated whether such relationships persisted in circumstances of abnormal glucose tolerance.MethodIn 224 type 2 diabetes subjects we assessed the ...

Radioactive iodine scanning and ablative radioactive therapy (RAI) are mainstays of follow-up and therapy in patients with differentiated thyroid carcinoma. TSH levels of 30 or greater are recommended as the levels required for effective use of RAI (see recent British Thyroid Association guidelines).To clarify our own practice we have studied 20 consecutive patients undergoing ablative RAI for thyroid carcinoma (10 papillary, 8 follicular and 2 mixed). The fourteen who had...

Glucocorticoid remediable aldosteronism (GRA) was first described in 1966 by Sutherland et ala. In this family, aldosterone secretion was regulated by ACTH and symptoms and signs were reversed by the administration of exogenous glucocorticoid. GRA is usually characterised by moderate to severe hypertension with early onset. The hypertension is often difficult to control and is associated with greatly increased vascular risk. It is inherited as an autosomal dominant trait and ...

Members of a hospital staff (n=332) were invited to complete a survey outlining dietary and lifestyle behaviour, and indicate if they were interested in a weight management programme. Height and weight were measured and body mass index (BMI) was calculated, in all respondents.Two hundred and sixty (78%) staff members responded, 60 males (23.1%) and 200 females (76.9%). The mean age of respondents was 36.5 yrs (35.8yrs males, 36.7yrs female). The mean bo...
