A 45-year-old woman presented with a 6-week history of constipation and generalised abdominal pains. Blood biochemistry revealed a corrected serum calcium of 4.99 mmol/l, phosphate 0.82 mmol/l, and intact parathyroid hormone (i-PTH) of 0.2 pmol/l (normal range 1–6.1 pmol/l). Serum parathyroid hormone related peptide (PTH-rP) was 5.3 pmol/l (normal range <1.8 pmol/l). Computed tomography demonstrated an 11.0×11.6 cm ovarian tumour with cystic and solid areas and h...

Glucagon is released from α-cells in the pancreatic islets and is best known for its role in glucose homeostasis. Glucagon/GLP-1 receptor co-agonists have recently been shown to improve glucose homeostasis and reduce body weight in diet-induced obese mice. Glucagon receptor agonism increases energy expenditure while the GLP-1 receptor agonism prevents glucagon-induced hyperglycemia. Peripherally administered glucagon is also capable of reducing food intake, and glucagon n...

A 50-year-old man with poorly controlled type 2 diabetes mellitus on oral hypoglycaemics was under review as a diabetic outpatient. In April 2007, he developed idiopathic thrombocytopaenic purpura which, on a background of probable diabetic nephropathy, precipitated end-stage renal failure. He was treated with oral steroids and was established on haemodialysis. To achieve better glycaemic control, he was converted to twice daily insulin. His treatment dose of prednisolone was ...
