ReviewAntiplatelet agents for preventing and treating pre-eclampsia.
Pre-eclampsia is associated with deficient intravascular production of prostacyclin, a vasodilator, and excessive production of thromboxane, a platelet-derived vasoconstrictor and stimulant of platelet aggregation. These observations led to the hypotheses that antiplatelet agents, and low dose aspirin in particular, might prevent or delay the development of pre-eclampsia. ⋯ Antiplatelet agents, in this review largely low dose aspirin, have small-moderate benefits when used for prevention of pre-eclampsia. Further information is required to assess which women are most likely to benefit, when treatment should be started, and at what dose.

ReviewProphylactic synthetic surfactant for preventing morbidity and mortality in preterm infants.
This section is under preparation and will be included in the next issue. ⋯ Prophylactic intratracheal administration of synthetic surfactant to infants judged to be at risk of developing respiratory distress syndrome has been demonstrated to improve clinical outcome. Infants who receive prophylactic synthetic surfactant have a decreased risk of pneumothorax, a decreased risk of pulmonary interstitial emphysema, and a decreased risk of neonatal mortality. Infants who receive prophylactic synthetic surfactant have an increased risk of developing patent ductus arteriosus and pulmonary hemorrhage.

Low back pain is one of the most common and costly musculoskeletal problems in modern societies. Proponents of massage therapy claim it can minimize pain and disability, and speed return to normal function. ⋯ Based on the studies reviewed, there is insufficient evidence to recommend massage as a stand-alone treatment for non-specific low back pain. There is a need for high quality controlled trials to further evaluate the effects of massage for this condition.

ReviewNeuraminidase inhibitors for preventing and treating influenza in healthy adults.
Influenza is an acute respiratory infection associated with raised temperature, headache, muscle ache and cough. The objective of this review was to assess the effects of neuraminidase inhibitors (NIs) in preventing cases of influenza and shortening or reducing the severity of influenza in healthy adults. A further objective was to estimate the frequency of adverse effects associated with NI administration. ⋯ NIs are effective for the prevention and treatment of influenza. Overall NIs are safe, although Oseltamivir causes significant nausea.

ReviewGastro-oesophageal reflux treatment for asthma in adults and children.
Asthma and gastro-oesophageal reflux are both common medical conditions and often co-exist. Studies have shown conflicting results concerning the effects of lower oesophageal acidification as a trigger of asthma. Furthermore, asthma might precipitate gastro-oesophageal reflux. Thus a temporal association between the two does not establish that gastro-oesophageal reflux triggers asthma. Randomised trials of a number of treatments for gastro-oesophageal reflux in asthma have been conducted, with conflicting results. ⋯ In asthmatic subjects with gastro-oesophageal reflux, (but who were not recruited specifically on the basis of reflux-associated respiratory symptoms), there was no overall improvement in asthma following treatment for gastro-oesophageal reflux. Subgroups of patients may gain benefit, but it appears difficult to predict responders.
