To determine the effects of available pharmacological interventions in treating the different clinical features of Behcet's syndrome. ⋯ We conclude that further randomized, placebo-controlled, double-blind trials should be carried out to compare cyclosporine, azathioprine and benzathine-penicillin versus placebo in order to make the results generalizable and comparable.

Leg oedema from venous insufficiency is not dangerous but it can cause women symptoms such as pain, feelings of heaviness, night cramps and paraesthesiae. Leg oedema can be a sign of pre-eclampsia when associated with raised blood pressure or proteinuria. ⋯ Rutosides appear to relieve symptoms of venous insufficiency in late pregnancy. However it is not known if the drug is safe in pregnancy. External pneumatic compression appears to reduce ankle swelling. Immersion in water for 50 minutes results in diuresis and fall in blood pressure. It is not known for how long these changes are sustained nor whether they are of any benefit.

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.

Piroxicam is a non-steroidal anti-inflammatory drug (NSAID) with analgesic properties, and is used mainly for treating rheumatic disorders. Some drugs have been directly compared against each other within a trial setting to determine their relative efficacies, whereas other have not. It is possible, however, to compare analgesics indirectly by examining the effectiveness of each drug against placebo when used in similar clinical situations. ⋯ Piroxicam appears to be of similar efficacy to other non-steroidal anti-inflammatory drugs (NSAIDs) and intramuscular morphine 10 mg when used as a single oral dose in the treatment of moderate to severe postoperative pain.

ReviewScreening for colorectal cancer using the faecal occult blood test, hemoccult.
Colorectal cancer is a leading cause of illness and death in the Western world. In Australia, the United Kingdom and the United States, it is the second commonest cancer for women after breast cancer (age-standardised incidence 22-33 per 100,000), and men after prostate or lung cancer (age-standardised incidence 31-47 per 100,000) (Jeffs et al, 1996; Parkin et al, 1992). Just under half of all persons affected will die from their disease (Jeffs et al, 1996; Parkin et al, 1992) The human and financial costs of this disease have prompted considerable research efforts to evaluate the ability of screening tests to detect the cancer at an early curable stage. Tests which have been considered for screening include faecal occult blood tests, sigmoidoscopy and colonoscopy. ⋯ Screening benefits include reduction in colorectal cancer mortality, possible reduction in cancer incidence through detection and removal of colorectal adenomas and potentially, treatment of early colorectal cancers may involve less invasive surgery. Harmful effects of screening include the physical complications of colonoscopy, disruption to lifestyle, stress and discomfort of testing and investigations, and the anxiety caused by falsely positive screening tests. Although screening benefits are likely to outweigh harms for populations at increased risk of colorectal cancer, we need more information about the harmful effects of screening, the community's responses to screening and screening costs for different health care systems before widespread screening can be recommended.
