An increasing number of elderly individuals are now undergoing coronary artery bypass surgery. Elderly patients, compared with patients of a younger age group, present for surgery with a greater burden of risk factors and reduced functional levels. Short-term outcomes are hence poorer in them. But symptom relief occurs in most survivors and is accompanied by excellent rates of long-term survival and a good quality of life. Therefore, an individualised risk-benefit profile must be carefully constructed by clinicians, taking into account several different factors and not just age alone. This review summarises the current concepts of coronary artery bypass surgery from the perspective of the very old.

The bacille Calmette-Guérin, a live attenuated form of Mycobacterium bovis, has been used as anti-cancer immunotherapy for superficial bladder cancer since 1976 [ 1]. It is now the mainstay of therapy for this condition, which is partly attributable to the low complication rate; indeed 95% have no significant side effects [ 2]. However, proven disseminated M. bovis infection has been documented, as is the case with our elderly patient.

SUMMARYHypoglycaemic haemiparesis (HH) is an uncommon but important presentation to the emergency department, and it often mimics stroke and is therefore frequently misdiagnosed by clinicians. The mechanism of haemiparesis is not fully understood. This case outlines a diabetic elderly woman, who had been having frequent hypoglycaemic episodes and presented to paramedics with hypoglycaemia associated with a right-sided haemiparesis. She was immediately transferred to the local stroke centre after presenting to the emergency department. CT and MRI did not fit in with her presenting neurology. Her weakness resolved, after normoglycaemia was achieved with dextrose infusion; however, she was reported to be more sleepy and drowsy than usual. After extensive and costly investigations during her prolonged inpatient stay, her unifying diagnosis was an HH which triggered of a hypoactive delirium. BACKGROUND

Antiphospholipid syndrome is a disorder of recurrent vascular thrombosis, pregnancy loss and thrombocytopenia associated with persistently elevated levels of antiphospholipid antibodies. It was first described in a group of patients with systemic lupus erythematosus but has since been associated with a wide range of conditions, including other autoimmune disorders and malignancy. It can also occur in isolation, the so-called primary antiphospholipid syndrome. We describe an elderly woman with the antiphospholipid syndrome thought to be associated with a cholangiocarcinoma.
