A 39-year-old man presented with thyrotoxicosis and was diagnosed with Graves’ disease. Despite high doses of anti-thyroid medication for 18 months, he remained biochemically and clinically hyperthyroid. Therefore, a thyroidectomy was planned. Four days before surgery, he developed double vision and was referred for urgent Neurosurgical review at our centre. On further questioning, he reported a 12-month history of lethargy and low libido. On examination, he had right 6th...

Background: Secondary adrenal insufficiency is a common complication of transsphenoidal hypophysectomy (TSS) for pituitary adenoma. It is therefore imperative to rapidly and accurately identify patients requiring glucocorticoid replacement, thus minimising risks of adrenal insufficiency or unnecessary glucocorticoid exposure. The gold-standard test of HPA axis reserve, the insulin tolerance test (ITT), cannot be performed safely until after post-operative recovery. Nine am cor...

Objective: To investigate whether a supervised structured exercise program by 16 weeks improves metabolic, pulmonary and cardiovascular parameters in obese adolescents.Material and methods: We included 38 obese adolescents between 12–15 years old. They participated in a supervised exercise program by 90 minutes, 5 days a week during 16 weeks. At baseline and at the end of the exercise program, we evaluated cardiorespiratory fitness, anthropometric m...

The definition of early cure post transphenoidal surgery (TSS) for Cushing’s disease continues to be debated. The low dose dexamethasone suppression test with corticotrophin releasing hormone (LDDST-CRH) is a test for diagnosis of Cushing’s; however it has not been validated in early post TSS to determine remission. The aim of this study was to determine whether the combined LDDST-CRH test could be used in post TSS patients.The combined LDDST-C...

Eliciting an accurate diagnosis of Cushing's disease before transphenoidal hypophysectomy is essential to avoid unnecessary surgery. Localisation of the tumour increases the chance of operative success.In the right hands, Inferior Petrosal Sinus Sampling (IPSS) can provide invaluable information in distinguishing ectopic ACTH from pituitary Cushing's and localising the tumour in patients who are known to have Cushing's syndrome. Due to the invasive natur...

Objectives: Metabolic dysfunction–associated fatty liver disease (MAFLD) is a new nomenclature for fatty liver disease (FLD). The clinical impact of the change in nomenclature on the ability to identify individuals at risk for cardiovascular disease (CVD) has not yet been elucidated. The aim of this study is to describe the cardiovascular risk and subclinical CVD of the different MAFLD subtypes.Methods: Retrospective analysis of patients who attende...

Introduction: Prolactinomas are the commonest type of secretory pituitary tumours. In current practice, dopamine agonists (DA) remain the mainstay treatment. However, treating physicians are increasingly aware of DA-associated impulse control disorders (ICD) in their patients. We describe 4 individuals with prolactinomas, who either developed ICD on DA or deemed at ‘high risk’, successfully managed surgically with preservation of pituitary function. All decisions for...

A 44 year old gentleman presented to his local hospital with a two week history of fevers and rigors. Blood cultures were positive for Streptococcus oralis, and an echocardiogram confirmed new diagnosis of hypertrophic cardiomyopathy (HCM) complicated by mitral valve infective endocarditis (IE). Unfortunately, this required a mechanical mitral valve replacement (MVR) and he started warfarin (INR target 2.5-3.5). During his admission, he reported chronic headaches. An MRI brain...

A 44-year-old gentleman presented to the Emergency Department with a 2-week history of fever and rigors. Past medical history was unremarkable other than an earlier diagnosis of hypertension. He was noted to have new onset atrial fibrillation with rapid ventricular response; a diagnosis of hypertrophic obstructive cardiomyopathy (HOCM) was made on echocardiography. In addition, a vegetation was identified on the mitral valve. Treatment for infective endocarditis (Streptoco...

Case history : A 44-year-old female presented with 6-week history of gradual deterioration in her left vision associated with eye pain. She saw an ophthalmologist who noted that she had reduced visual acuity (6/24) and colour vision (Ishihara colour vision score 3/15) in her left eye with left relative afferent pupillary defect (RAPD). It was thought that she may have a left retrobulbar neuritis so she was advised to attend A&E for an urgent neurology assessment. On examin...
