Antibiotic treatment of acute bronchitis, which is one of the most common illnesses seen in primary care, is controversial. Most clinicians prescribe antibiotics in spite of expert recommendations against this practice. ⋯ Overall, antibiotics appear to have a modest beneficial effect in patients who are diagnosed with acute bronchitis. The magnitude of this benefit, however, is similar to that of the detriment from potential adverse effects. Furthermore, patients with other symptoms of the common cold who have been ill for less than one week are not likely to have any benefit from antibiotics.

ReviewAnticoagulants for preventing stroke in patients with nonrheumatic atrial fibrillation and a history of stroke or transient ischemic attacks.
People with nonrheumatic atrial fibrillation who have had a transient ischemic attack or a minor ischemic stroke are at risk of recurrent stroke. ⋯ The evidence suggests that anticoagulants are beneficial, without serious adverse effects, for people with nonrheumatic atrial fibrillation and recent cerebral ischaemia.

The role of chemotherapy in the treatment of patients with non-small cell lung cancer was not clear. A systematic review and quantitative meta-analysis was therefore undertaken to evaluate the available evidence from all relevant randomised trials. ⋯ At the outset of this meta-analysis there was considerable pessimism about the role of chemotherapy in the treatment of non-small cell lung cancer. These results offer hope of progress and suggest that chemotherapy may have a role in treating this disease.

ReviewAnticoagulants versus antiplatelet therapy for preventing stroke in patients with nonrheumatic atrial fibrillation and a history of stroke or transient ischemic attacks.
People with nonrheumatic atrial fibrillation who have had a transient ischemic attack or minor ischemic stroke are at risk of recurrent stroke. ⋯ The evidence from one trial suggests that anticoagulant therapy can benefit people with nonrheumatic atrial fibrillation and recent cerebral ischaemia. Aspirin may be a useful alternative if there is a contraindication to anticoagulant therapy. The risk of adverse events appears to be higher with anticoagulant therapy than aspirin.

Whilst carotid endarterectomy (CEA) is of proven benefit in recently symptomatic patients with severe carotid stenosis, the role of carotid endarterectomy in preventing stroke in patients with asymptomatic carotid stenosis remains uncertain. ⋯ There is some evidence favouring CEA for asymptomatic carotid stenosis, but the effect is at best barely significant, and extremely small in terms of absolute risk reduction.
