Electrocardiographical case. A tale of tall T's. Hyperkalaemia.

A 63-year-old woman presented at the emergency department (ED) with a history of increasing lethargy and drowsiness. The electrocardiogram (ECG) showed tall peaked T waves with broadening of the QRS interval, suggestive of hyperkalaemia. This patient had an elevated serum potassium level due to diabetic ketoacidosis. She was treated with intravenous calcium chloride and insulin with 50% dextrose. The ECG changes associated with hyperkalaemia are discussed, with illustrations from a second 48-year-old male patient with renal failure who presented with malaise, lethargy and generalised weakness.

Electrocardiographical case. ST elevation: is this an infarct? Pericarditis.

A 25-year-old man presented at the emergency department with complaints of fever and chest pain. The electrocardiogram (ECG) showed concave ST segment elevation that was not confined to any arterial territory. There was PR segment elevation in lead aVR as well as PR segment depression in leads II, V5 and V6. This was consistent with pericarditis. The electrocardiographical changes associated with pericarditis are discussed. A second case of a 64-year-old man with uraemic pericarditis with similar ECG changes is illustrated.

An unusual corneal complication of soft contact lens.

An unusual complication caused by hydrophilic soft contact lenses developed in 13 patients (ten women and three men, 16 to 39 years old), most of whom had tight eyelids. The lesion consisted of an arc-like opacity in the superior cornea. The opacity lay in the superficial cornea about 1 to 3 mm from the corneoscleral limbus and had fine spokes extending away from the main trunk. In some cases the problem was unilateral and in others bilateral.
