ReviewElastic compression stockings for prevention of deep vein thrombosis.
One of the settings in which deep vein thrombosis (DVT) in the lower limb and pelvic veins occurs is prolonged immobilisation in hospital for various surgical and medical illnesses. Use of graduated compression stockings (GCS) in these patients has been proposed to decrease the risk of DVT. ⋯ Analysis of these RCT's confirm that GCS are effective in diminishing the risk of DVT in hospitalised patients. Data examination also suggests, that GCS on a background of another method of prophylaxis is even more effective than GCS alone.

ReviewHolding chambers versus nebulisers for beta-agonist treatment of acute asthma.
In acute asthma inhaled beta-agonists are often administered to relieve bronchospasm by wet nebulisation, but some have argued that metered-dose inhalers with a holding chamber (spacer) can be equally effective. In the community setting nebulisers are more expensive, require a power source and need regular maintenance. ⋯ Metered-dose inhalers with holding chamber produced outcomes that were at least equivalent to nebuliser delivery. Holding chambers may have some advantages compared to nebulisers for children with acute asthma.

ReviewThienopyridine derivatives (ticlopidine, clopidogrel) versus aspirin for preventing stroke and other serious vascular events in high vascular risk patients.
The most widely studied and prescribed antiplatelet agent for the prevention of stroke and other serious vascular events among high vascular risk patients is aspirin. Aspirin inhibits platelet activation by inhibiting platelet cyclooxygenase and thromboxane production, and reduces the odds of a serious vascular event by about a quarter. The thienopyridines (ticlopidine and clopidogrel) inhibit platelet activation by a different mechanism to aspirin (blocking the ADP receptor on platelets), and so may be more effective than aspirin. ⋯ The available randomised evidence shows that the thienopyridine derivatives are modestly but significantly more effective than aspirin in preventing serious vascular events in patients at high risk (and specifically in TIA/ischaemic stroke patients), but there is uncertainty about the size of the additional benefit. The thienopyridines are also associated with less gastrointestinal haemorrhage and other upper gastrointestinal upset than aspirin, but an excess of skin rash and diarrhoea. The risk of skin rash and diarrhoea is greater with ticlopidine than with clopidogrel. Ticlopidine, but not clopidogrel, is associated with an excess of neutropenia and of thrombotic thrombocytopenic purpura.

ReviewProstaglandins versus oxytocin for prelabour rupture of membranes at or near term.
The conventional method of induction of labour is with intravenous oxytocin. More recently, induction with prostaglandins, followed by an infusion of oxytocin if necessary, has been used. ⋯ Women with prelabour rupture of membranes at or near term having their labour induced with prostaglandins appear to have a lower risk of epidural analgesia and fetal heart rate monitoring. However there appears to be an increased risk of chorioamnionitis and nausea/vomiting with prostaglandins compared to oxytocin.

ReviewOn-site mental health workers in primary care: effects on professional practice.
Mental health problems are common in primary care and mental health workers (MHWs) are increasingly working in this setting. In addition to treating patients, the introduction of on-site MHWs may lead to changes in the clinical behaviour of primary care providers (PCPs). ⋯ This review does not support the hypothesis that adding MHWs to primary care provider organisations in 'replacement' models causes a significant or enduring change in PCP behaviour. 'Consultation-liaison' interventions may cause changes in psychotropic prescribing, but these seem short-term and limited to patients under the direct care of the MHW. Longer-term studies are needed to assess the degree to which demonstrated effects endure over time.
