Assay interference with various laboratory measurements has been reported in the presence of paraproteins. We report a case of a 57 year old woman, who was referred to endocrine clinic after being found to have elevated total vitamin D levels of 369 and 336 nmol/l (normal 50–100 nmol/l). She was not known to be on any Vitamin D supplements that could account for such high levels. Around the time of referral, she was also diagnosed with IgM paraproteinaemia. Therefore, pos...

Introduction: Commonest causes of pancreatitis are alcohol and gallstones but less common causes like hypertriglyceridemia should also be considered as management may differ.Case history: 47 years old gentleman with history of pancreatitis and hyperlipidaemia type1 taking atorvastatin and bezafibrate, admitted with severe abdominal pain and vomiting. He was non-smoker and non-drinker. No history of cholelithiasis or medications causing pancreatitis. He w...

Background: Elevated TSH concentration should be assessed and treated with caution because of the possibility of transient thyroid dysfunction, or, in rare cases, measurement interference. We describe a case with a rare cause of elevated TSH level in a 39-year-old mother and her four children.Case Summary: A 39-year-old lady was referred with a long history of high serum TSH ranging between 18.9 to 38.7 (reference interval 0.4-4.0 mU/l) with FT4 concentr...

Objective: To evaluate the GRI and its association with other CGM metrics after initiation of automated insulin delivery (AID) system in adults with type 1 diabetes (awT1D).Methods: Up to 90 days of CGM data before and after initiation of an AID system from 185 awT1D were collected. GRI with hypoglycemia and hyperglycemia components and other CGM metrics were calculated using cgmanalysis R software and analyzed for 24-hour, nighttime, and daytime. GRI va...

Introduction: Dermoid cysts are rare (0.5% of intracranial tumours). They are best considered a spectrum: from epidermoid cysts containing desquamated squamous epithelium to teratomas containing all three embryonic tissues. Sellar dermoid cysts are even rarer [Orpha.net ID: ORPHA:91351]. Case: A 47-year old white British male was referred following incidental discovery of bitemporal field defect on routine eye test. He was otherwise completely asymptomat...

The pituicytomas are extremely rare and little-studied primary tumours of the adult neurohypophysis. These are low-grade (World Health Organization [WHO] grade 1), indolent gliomas which present as a sellar mass, which is usually mistaken for a pituitary adenoma, and has no known hormonal secretory function. A 63 years old retired paediatrician was referred to the neurology clinic with the history of constant severe headache ongoing for a few weeks. It involved the whole of th...

Introduction: Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is documented as a pre-malignant condition by the World Health Organisation. Patients with pulmonary nodules typically undergo 5′-18fluoro-deoxy-D-glucose (FDG) positron emission tomography combined with computed tomography (PETCT) for further diagnostic investigation. DIPENCH is widely accepted as an FDG negative pathology. The purpose of this analysis was to a...

A 30-year-old teacher with no past medical history presented with a 3 month history of muscle weakness, pain and spasms together with cold intolerance, weight gain and fatigue.
