Case: A 79 years old frail lady with history of dementia and hypertension presented with refractory hypoglycaemia over a period of 3 months requiring multiple admissions. During her most recent admission, she required continuous dextrose infusion to maintain euglycaemia. The severe spontaneous hypoglycaemia in this non-diabetic lady, warranted a series of investigations. TFT and Short Synacthen Test excluded thyroid dysfunction and hypoad...

Background/methodsPatients with uncontrolled acromegaly or receiving high cost medical therapy despite initial treatment, usually transsphenoidal surgery (TSS), were considered for a ¹¹C-methionine PET-CT scan (11C-Met PET-CT). This imaging technique may identify a target for TSS or radiotherapy when MRI appearances are inconclusive1. In preparation, four patients on long-term SSA were taken off treatment 3 months prior to the scan. ...

Background /Methods: Adrenal incidentalomas pose a significant burden to endocrinology services in assessing the clinical significance of these lesions. Following vetting of the incidentaloma referrals, the patients at our centre are initially seen in a nurse-led clinic for biochemical investigations and to ensure completion of radiology assessment using a structured proforma. This step facilitates efficient patient flow and quicker decision making. The clinical outcomes of th...

Background11C-methionine (11C-Met) positron emission tomography co-registered with MRI is a new imaging technique used for functioning pituitary adenomas, permitting targeted intervention (Transphenoidal Surgery (TSS) or Radiotherapy)1. The 11C-Met PET-CT scan has been available in our centre since Dec 2016. With limited availability in 2019/2020 (due to cyclotron refurbishment) we re-audited our patients to prioritise th...

Obesity increases the risk of certain cancers, especially tumours that reside close to adipose tissue (e.g. breast cancers and ovarian metastasis to omentum). Adipose tissue in obesity and tumour micro-environmentsshare a common pathogenic feature, oxygen deprivation (hypoxia, Hx). Here we hypothesised that this hypoxic microenvironment causes changes in key metabolic pathways in adipocytes leading to increased cancer cell growth. To test this, human or mouse breast (BC) and o...

A 28-year-old female presented to ED with one week history of flu-like symptoms, palpitations, increasing breathlessness, and productive cough with copious sputum, of two days duration. There was h/o some weight loss over the last year, with episodic palpitations over the last 8-10 years that increased in frequency over the last one year. She had a family history of hyperthyroidism paternally and maternally. On examination, there was mild lid-lag and proptosis. She was tachypn...

Introduction: Polycystic Ovary Syndrome (PCOS) affects 5-10% of childbearing females and, up to 20% in specific ethnic populations (i.e. South Asians and Hispanics). It is linked with a higher prevalence of obesity and metabolic dysfunction, resulting in increased risk for dyslipidaemia, impaired glucose tolerance, type 2 diabetes mellitus (T2DM) and cardiovascular diseases.Methods: This is a retrospective study of patients diagnosed with PCOS (n</em...

Aim: Increasing left ventricular mass index (LVMI) is associated with a poor prognosis in patients with chronic kidney disease (CKD). Blockade of the mineralocorticoid receptor (MR) in CKD leads to improvement in proteinuria and LV mass. However, the MR can be activated by aldosterone, cortisol and deoxycorticosterone (DOC) and their relative contribution to adverse events in CKD is unclear. We aimed to assess the correlation between mineralocorticoid excretion and LVMI in pat...

Delayed hyponatraemia(DH) is a well-known complication following trans-sphenoidal pituitary surgery (TSS), varying in incidence from 9–36% and occurs between post-operative days(POD) 4 to 14. Various studies have demonstrated that post-operative fluid restriction after TSS reduces the incidence of DH.Objective: to assess whether a fluid restriction protocol from POD5 to POD14 following TSS reduces the incidence of post-operative DH ...
