Review Meta AnalysisHaloperidol plus promethazine for psychosis induced aggression.
Health services often manage agitated or violent people and for emergency psychiatric services such behaviour is particularly prevalent (10%). The drugs used in this situation should ensure that the person swiftly and safely becomes calm. ⋯ This review suggests that both benzodiazepines work, but that midazolam has a faster onset and thereby reduces the risk of exposure to violence. Both benzodiazepines have the potential to cause respiratory depression, probably midazolam more so than lorazepam, and we would question the use of this group of drugs outside of those services fully confident of observing for and managing the consequences of respiratory distress. Most evidence, however, exists for the haloperidol plus promethazine mix, with currently more than 400 people randomised to the combination. The onset of action is swift and faster than lorazepam. The combination also seems safe with no clear longer term consequences. We would expect policy makers recommending other drug managements to have equally compelling evidence to support their guidance and hope that this would not be founded in conjecture or consensus, which may be more difficult to defend than evidence from high quality studies.

Review Meta AnalysisElectrical cardioversion for atrial fibrillation and flutter.
Atrial fibrillation increases stroke risk and adversely affects cardiovascular haemodynamics. Electrical cardioversion may, by restoring sinus rhythm, improve cardiovascular haemodynamics, reduce the risk of stroke, and obviate the need for long-term anticoagulation. ⋯ Electrical cardioversion (rhythm control) led to a non-significant increase in stroke risk but improved three domains of quality of life.

Review Meta AnalysisCorticosteroids for aneurysmal subarachnoid haemorrhage and primary intracerebral haemorrhage.
Corticosteroids, particularly dexamethasone, are commonly used for treatments in patients with subarachnoid haemorrhage (SAH) and primary intracerebral haemorrhage (PICH) despite the lack of evidence. ⋯ Overall, there is no evidence of a beneficial or adverse effect of corticosteroids in patients with either SAH or PICH. Confidence intervals are wide and include clinically significant effects in both directions.

Review Meta AnalysisAcupuncture and dry-needling for low back pain.
Although low-back pain is usually a self-limiting and benign disease that tends to improve spontaneously over time, a large variety of therapeutic interventions are available for its treatment. ⋯ The data do not allow firm conclusions about the effectiveness of acupuncture for acute low-back pain. For chronic low-back pain, acupuncture is more effective for pain relief and functional improvement than no treatment or sham treatment immediately after treatment and in the short-term only. Acupuncture is not more effective than other conventional and "alternative" treatments. The data suggest that acupuncture and dry-needling may be useful adjuncts to other therapies for chronic low-back pain. Because most of the studies were of lower methodological quality, there certainly is a further need for higher quality trials in this area.

Review Meta AnalysisTransient neurologic symptoms (TNS) following spinal anaesthesia with lidocaine versus other local anaesthetics.
Spinal anaesthesia has been in use since the turn of the late nineteenth century. During the last decade there has been an increase in the number of reports implicating lidocaine as a possible cause of temporary and permanent neurologic complications after spinal anaesthesia. Follow-up of patients who received uncomplicated spinal anaesthesia revealed that some of them developed pain in the lower extremities after an initial full recovery. This painful condition that occurs in the immediate postoperative period was named "transient neurologic symptoms" (TNS). ⋯ The risk of developing TNS after spinal anaesthesia with lidocaine was significantly higher than when bupivacaine, prilocaine and procaine were used. The term "TNS", which implies a positive neurologic finding, should not be used for this painful condition. One study about the impact of TNS on patient satisfaction and functional impairment demonstrated that non-TNS patients were more satisfied and had less functional impairment after surgery than TNS patients, but this did not influence their willingness to recommend spinal anaesthesia.
