TSH receptor antibodies (TRAb) are autoantibodies directed against the TSH receptor, predominantly located on the thyroid epithelial cell surface. Two types of TSH receptor antibody have been found to exist in patients with autoimmune thyroid disease: thyroid stimulating antibodies (TSAb) and TSH-stimulation blocking antibodies (TSBAb). It has generally been felt that patients with positive TSAbs develop Graves’ hyperthyroidism and those with TSBAb antibodies develop hypo...

Hyponatremia is the commonest electrolyte abnormality presenting to Medical Admissions and when acute, severe and symptomatic, is associated with high mortality. The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the most common underlying disorder in hospitalised patients with euvolaemic hyponatraemia and is a complication of many clinical conditions and drug therapies.We discuss the cases of two patients...

Ectopic Cushing’s syndrome (CS) is commonly caused by malignancy, often behaves aggressively and may not clinically manifest with features of hypercortisolism due to its rapid course and associated cachexia. This may mislead clinicians into discounting the diagnosis in patients with more indolent features of CS. We present a 41 year old woman with an 8 year history of Cushingoid features with associated hypertension, obesity and Type 2 Diabetes. Investigations confirmed C...
