Severe Hypercalcaemia can present as a life threatening emergency requiring urgent measures to lower the calcium. Usually, this is associated with Primary Hyperparathyroidism. It can result in obtundation, oliguria, anuria, collapse or arrhythmias. It is important to act fast and decisively to prevent fatal complications.We describe a 39 year old gentleman who was a tennis coach, who was brought after he collapsed in his bathroom. ...

Background: Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum of diseases starting with pathological accumulation of intrahepatocellular triglyceride (TG) (i.e. steatosis), which can progress to steatohepatitis (NASH) and cirrhosis. Insulin resistance is often associated with the development of steatosis and disease progression however, the underlying mechanisms for this are poorly defined. A major challenge in modelling human NAFLD disease progression is the la...

G protein-coupled receptors are the largest family of mammalian receptors, with key roles in controlling most physiological processes. Ovarian function is no exception, with a key ovarian GPCR, follicle stimulation hormone receptor (FSHR), and its endogenous ligand, FSH, critical for pre-antral-antral follicle growth and survival. An increasingly important way that GPCRs have been shown to regulate ligand specificity and signal amplitude is via association and formation of dim...

Background: Nice guideline recommends using TSH receptor antibody as a tool for classification of hyperthyroid patients; and considering technetium scanning of the thyroid gland if TRAbs are negative. Early diagnosis of TED is also essential for treatment to be effective. The most common way to assess the severity of TED is to use the Clinical Activity Score (CAS) 7-point scale.Objectives: We aimed to evaluate if hyperthyroid patients are classified corr...

Ovarian aging is a naturally occurring physiological process, marked by dynamic changes in ovarian function and hormone secretion. Ovarian ageing is associated with several co-morbidities, including; osteoporosis, diabetes, cardiovascular disease and impaired cognitive function, therefore, understanding the physiological processes regulating this is imperative for identifying novel treatment modalities. A key endocrine regulatory of ovarian function is the heterodimer glycopro...

Pseudohypoparathyroidism type 1b (PHPT1b) is a rare disorder due to resistance to parathyroid hormone (PTH) and subsequent hypocalcaemia, hyperphosphataemia and normal or raised PTH levels. Sufferers usually present in childhood with seizures or tetany due to hypocalcaemia. Typically, PHPT1b is associated with defects on the long-arm of chromosome 20 in the form of uniparental (paternal) disomy of 20q or genetic mutations or sporadic epigenetic changes in GNAS gene. G...

Background: ‘Glycaemic tracking’ describes the stability of HbA1c over time commonly observed in individuals with type 1 diabetes (T1DM). Preliminary studies have noted the relationship between early metabolic control and long-term outcomes, while recent evidence has been presented for glycaemic tracking in a large number of newly diagnosed individuals with T1DM. The benefits of tight glycaemic control, in terms of reducing microvascular complications and lowering Hb...

Introduction: There are many causes of rhabdomyolysis, with Carbimazole, the first line treatment for hyperthyroidism, being one of the rarest. Rhabdomyolysis can potentially cause significant morbidity and mortality if left untreated.Case: A 38 year old female presented to the Emergency Department in May 2018 with a 4 day history of severe sudden onset bilateral thigh pain. Her only prior health problem was primary hyperthyroidism for which she had been...

Introduction: Measurement of plasma metanephrines (PMETS) is widely regarded as one of the best screening tests for phaeochromocytoma/paraganglioma (P/PGL). Current Endocrine Society guidelines recommend that samples for PMETS are ideally collected in the supine position after 30 min rest and interpreted using supine reference ranges, in order to optimise the diagnostic performance of the test. Current practice in our centre is to collect samples for PMETS from seated patients...
