Persistently elevated CKMB and negative troponin T in a patient at ischaemic risk with chest pain.

Analytical interference in laboratory assays is not only unpredictable but also an underestimated problem. Not recognising these interferences can lead to misdiagnosis and mismanagement of patients. We present a case of a patient with chest pain and ischaemic risk factors with incongruent biochemical results.

Ischemic stroke in a man using estrogen.

Ischemic cerebrovascular disease has been associated with oral contraceptives but not standard hormone replacement in women. It is unknown whether or not estrogen therapy in a male is associated with an increased risk of stroke. We report a single case of a genetic male taking high doses of estrogen and progesterone who suffered a stroke.

Benign angioedema after thrombolysis for acute stroke.

We present a case of acute angioedema after administration of recombinant tissue plasminogen activator (t-PA) for acute ischemic stroke. Our patient was treated with t-PA in accordance with the National Institute of Neurological Disorders and Stroke (NINDS) protocol, and subsequently developed angioedema of the lower lip that subsided within 2 hours. Five patients who required upper airway control after the use of t-PA for ischemic stroke have been reported in the literature.
