Introduction: Calcium sensing receptor (CaSR) plays a role in calciotropic processes by regulating parathyroid hormone secretion and urinary calcium excretion. Activating mutation of the CaSR, with heterozygous gain in function, causes autosomal dominant hypocalcaemia 1 (ADH1), a rare disorder with a prevalence of 3.9 per 100,000. Aggressive treatment to normalise serum calcium causes nephrocalcinosis and hypercalcaemia. We present a case of a 27-year-old female with CaSR muta...

Introduction: Silent corticotroph adenomas(SCA) are defined as pituitary adenomas showing positive staining for adrenocorticotrophic hormone in immunohistochemical studies not associated with clinical/laboratory features of hypercortisolaemia. We report a case of SCA in a 61-year-old man, who presented with pituitary apoplexy.Case presentation: Patient presented with persistent diplopia of 3 months duration, associated with severe headache for 1 week. He...

Neuromyelitis Optica (NMO) is a neuro-inflammatory condition usually presenting with optic nerve and spinal cord events, caused by autoimmunity to Aquaporin 4 (AQ4) channels in the central nervous system (CNS). The high density of AQ4 channels in the hypothalamus and area postrema mean that NMO can occasionally present with atypical features. We present a 56-year old South Asian man, who presented with hiccoughs and Syndrome of inappropriate antidiuretic hormone (SIADH ) and w...

Introduction: Coexistence of primary hyperparathyroidism and plasma cell dyscrasias such as multiple myeloma and monoclonal gammopathy of uncertain significance (MGUS) is rare. This can cause diagnostic uncertainty regarding the aetiology and relative contribution of each disorder to hypercalcaemia. We present a series of five individuals with this combination.Case series: All five patients were referred to the endocrine clinic with hypercalcaemia. The s...

Background: Primary aldosteronism (PA) is a common, curable and high-risk subset of hypertension, mandating detection. In all but the most severe cases, learned society guidelines recommend confirmatory testing. Whilst a variety of confirmatory tests exist, data describing their safety are limited. Concerns centre around the potential of some tests to precipitate hypokalaemia or a hypertensive emergency in a patient with PA on sub-optimal anti-hypertensive medication. In this ...

Introduction: Diabetes mellitus is as a major contributor to disease severity and mortality in patients with Covid-19 infection, as the estimated increase in risk of death in hospitalised patients is 3.5-times (for T1DM) and 2.03-times (for T2DM).This retrospective analysis recruited 35 patients from three London hospitals who presented with diabetic emergencies i.e. diabetic ketoacidosis (DKA), Hyperglycaemic hyperosmolar state( HHS), presence of ketone...
