If case reports be the food of knowledge, write on: our Cases of the Quarter.

The value of publishing case reports has long been debated and the arguments are summarised. Last year, to encourage trainees, the Royal College of Physicians of Edinburgh's Senior Fellows Club inaugurated an annual prize for the best case report or case series published in the Journal of the Royal College of Physicians of Edinburgh by a doctor in training. Some of the highlights of last year's entries are reviewed, commented on and developed. They include cases of myelofibrosis and cherubism due to secondary hyperparathyroidism from renal failure; reversible blindness in diabetic ketoacidosis; the long QT syndrome; ictal asystole; giant cell arteritis; tumour necrosis factor-α inhibition in Lyme borreliosis; and cannabis hyperemesis syndrome.
