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.

ReviewProphylactic syntometrine versus oxytocin for delivery of the placenta.
The routine prophylactic administration of an oxytocic agent is an integral part of active management of the third stage of labour. These agents help prevent postpartum haemorrhage. ⋯ The use of the combination preparation syntometrine (oxytocin and ergometrine) as part of the routine active management of the third stage of labour appears to be associated with a statistically significant reduction in the risk of postpartum haemorrhage when compared to oxytocin where blood loss is less than 1000ml. No difference was seen between the groups using either five or 10 international units for blood loss equal to or greater than 1000 millilitres. This needs to be weighed against the more common adverse effects associated with the use of syntometrine.

ReviewPostoperative caffeine for preventing apnea in preterm infants.
Growing ex-preterm infants who undergo general anesthesia for surgery at about term-equivalent age may have episodes of apnea, cyanosis and bradycardia during the early postoperative period. Caffeine treatment given at the time of operation might prevent these episodes. ⋯ Implications for practice. Caffeine can be used to prevent postoperative apnea/bradycardia and episodes of oxygen desaturation in growing preterm infants if this is deemed clinically necessary. In view of the small numbers of infants studied in these trials and uncertainty concerning the clinical significance of the episodes, caution is warranted in applying these results to routine clinical practice. Implications for research. There is a need to determine which infants might benefit most by this treatment. Studies confined to those most at risk of apnea (prior history, younger postmenstrual age) and those that might require mechanical ventilation (chronic lung disease) would be of value.

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.

Maintenance of optimal lung function is an important therapeutic goal in cystic fibrosis as it is lung damage that, in the long term, is responsible for most premature death among affected people. Inhaled corticosteroids are being increasingly used to treat children and adults with cystic fibrosis. The rationale for their use is that they have the potential to reduce lung damage arising from inflammation. However chronic use of inhaled steroids may also have adverse effects. It is thus important to establish the current level of evidence about the potential benefits and harms of this practice. ⋯ Nine trials were identified reporting the use of inhaled steroids in 266 subjects aged between seven and 45 years with cystic fibrosis. Methodological quality was difficult to assess from published information, specifically with respect to concealment of allocation and method used to generate random sequence. Trials were heterogeneous with respect to inclusion criteria, specifically age, severity of pulmonary involvement, clinical diagnosis of asthma and pulmonary colonisation with Pseudomonas aeruginosa. Trials also differed in type and duration of treatment. Beclomethasone was given for periods of between four and 22 weeks in four trials, budesonide for six weeks and six months respectively in two, and fluticasone for periods of between six weeks and two years in the remaining three. Measures of the volume of air breathed out on a forcible expiration (forced expiratory volumes) were reported in most trials but these data could not be combined for this review partly because reports differed in the way data were summarised and partly because some data were not included in published reports. Outcomes of potentially greater relevance to affected individuals such as nutritional status or quality of life were not reported in any trial. Survival was not reported in any trial, but this may reflect the fact that maximum duration of follow up was too short to allow this outcome to be meaningfully assessed. Adverse effects were systematically documented in only two trials. Although one trial was halted prematurely because a proportion of all those taking part had acquired chronic lung infections with Pseudomonas aeruginosa, no conclusions can be reached from this one small trial as to whether this risk is increased as
