ReviewContinuous infusion versus intermittent flushing to prevent loss of function of peripheral intravenous catheters used for drug administration in newborn infants.
The use of peripheral intravenous cannulae is common in newborn babies. Many of them require an intravenous line only for medications and not for fluid. Currently there is little uniformity in methods used to maintain cannula patency. ⋯ It is difficult to draw reliable conclusions given the way the data were analysed and reported in the two included studies. The reliability of the results is uncertain. However, given the caution in interpreting these data, it should also be noted that the use of intermittent flushes was not associated in either study with a decreased cannula life or any other disadvantages, thus lending some support for the use of intermittent flushing of cannulas in a selected population in neonatal nurseries.

Obstructive sleep apnoea/hypopnoea syndrome(OSAHS) is the periodic reduction or cessation of airflow during sleep. The syndrome is associated with loud snoring, disrupted sleep and observed apnoeas. Surgery for obstructive sleep apnoea/hypopnoea syndrome aims to alleviate symptoms of daytime sleepiness, improve quality of life, and reduce the signs of sleep apnoea recorded by polysomnography. ⋯ There are now a small number of trials assessing different surgical techniques with inactive and active control treatments. The studies assembled in the review do not provide evidence to support the use of surgery in sleep apnoea/hypopnoea syndrome, as overall significant benefit has not been demonstrated. The participants recruited to the studies had mixed levels of AHI, but tended to suffer from moderate daytime sleepiness where this was measured. Short-term outcomes are unlikely to consistently identify suitable candidates for surgery. Long-term follow-up of patients who undergo surgical correction of upper airway obstruction is required. This would help to determine whether surgery is a curative intervention, or whether there is a tendency for the signs and symptoms of sleep apnoea to re-assert themselves, prompting patients to seek further treatment for sleep apnoea.

ReviewImmunosuppressant and immunomodulatory treatment for dermatomyositis and polymyositis.
Idiopathic inflammatory myopathies are chronic skeletal diseases with significant mortality and morbidity despite treatment by corticosteroids. Immunosuppressive agents and immunomodulatory therapy are used to improve disease control and reduce the long-term side effects of corticosteroids. While these treatments are used commonly in routine clinical practice, the optimal therapeutic regimen remains unclear. ⋯ This systematic review highlights the lack of high quality randomised controlled trials that assess the efficacy and toxicity of immunosuppressants in inflammatory myositis.

ReviewNSAIDS or paracetamol, alone or combined with opioids, for cancer pain.
NSAIDs are widely applied to treat cancer pain and are frequently combined with opioids in combination preparations for this purpose. However, it is unclear which agent is most clinically efficacious for relieving cancer-related pain, or even what may be the additional benefit of combining an NSAID with an opioid in this setting. ⋯ Based upon limited data, NSAIDs appear to be more effective than placebo for cancer pain; clear evidence to support superior safety or efficacy of one NSAID over another is lacking; and trials of combinations of an NSAID with an opioid have disclosed either no difference (4 out of 14 papers), a statistically insignificant trend towards superiority (1 out of 14 papers), or at most a slight but statistically significant advantage (9 out of 14 papers), compared with either single entity. The short duration of studies undermines generalization of their findings on efficacy and safety of NSAIDs for cancer pain.

ReviewTranscutaneous electrical nerve stimulation (TENS) for chronic low-back pain.
Chronic low-back pain (LBP) affects a significant proportion of the population. Transcutaneous electrical nerve stimulation (TENS) was introduced more than 30 years ago as an adjunct to the pharmacological management of pain. However, despite its widespread use, the usefulness of TENS in chronic LBP is still controversial. ⋯ There is inconsistent evidence to support the use of TENS as a single treatment in the management of chronic LBP. Larger, multi-center, randomized controlled trials are needed to better assess the true effectiveness of TENS. Special attention should be given to the risks and benefits of long-term use, which more appropriately addresses the realities of managing chronic low-back pain.
