ReviewChest radiograph in acute respiratory infections in children.
Chest radiography is widely used in acute lower respiratory infection in children, but the benefits are unknown. ⋯ There is no evidence that chest radiography improves outcome in ambulatory children with acute lower respiratory infection. The findings do not exclude a potential effect of radiography, but the potential benefit needs to be balanced against the hazards and expense of chest radiography. The findings apply to ambulatory children only.

ReviewDuration of treatment with vitamin K antagonists in symptomatic venous thromboembolism.
Currently the most frequently used secondary treatment for patients with venous thromboembolism are vitamin K antagonists targeted at an INR of 2.5 (range 2.0 - 3.0). However, based on the continuing risk of bleeding and uncertainty regarding the risk of recurrent venous thromboembolism, there is discussion on the proper duration of treatment with vitamin K antagonists for these patients. Recently, several studies were published in which the risk and benefits of different durations of oral anticoagulants were compared in patients with venous thromboembolism. ⋯ In conclusion this meta-analysis shows that treatment with vitamin K antagonists reduces the risk of recurrent venous thromboembolism as long as it is used. However, the absolute risk of recurrent venous thromboembolism declines over time, while the risk for major bleeding remains. Thus, the efficiency of vitamin K antagonist administration decreases over time since the index event.

ReviewPharmacological interventions for spasticity following spinal cord injury.
Spasticity is a major health problem for patients with a spinal cord injury (SCI) that limits patients' mobility and affects independence in activities of daily living and work. Spasticity may also cause pain, loss of range of motion, contractures, sleep disorders and impair ambulation in patients with an incomplete lesion. The effectiveness of available drugs is still uncertain and they may cause adverse effects. Assessing what works in this area is complicated by the lack of valid and reliable measurement tools. The aim of this systematic review is to critically appraise and summarise existing information of the effectiveness of available treatments and to identify areas where further research is needed. ⋯ There is insufficient evidence to assist clinicians in a rational approach to antispastic treatment for SCI. Further research is urgently needed to improve the scientific basis of patient care.

ReviewProstaglandins versus oxytocin for prelabour rupture of membranes at 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 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 neonatal infections after prostaglandin induction compared to oxytocin.

Misoprostol is a synthetic prostaglandin which has been used to induce labour. Oral use of the drug misoprostol may be convenient, but an overdose could cause uterine hyperstimulation and precipitate labour which may be life-threatening for both mother and fetus. ⋯ Oral misoprostol may be an effective method for labour induction. However, the data on safety are lacking. It is possible that clinically effective oral regimens may have an unacceptably high incidence of complications such as uterine hyperstimulation and possibly uterine rupture.
