Review Meta AnalysisMechanical bowel preparation for elective colorectal surgery.
For over a century the presence of bowel content during surgery has been linked to anastomotic leakage. Mechanical bowel preparation has been considered an efficient agent against leakage and infectious complications. This dogma is not based on solid evidence, but on observational data and expert's opinions. ⋯ There is no convincing evidence that mechanical bowel preparation is associated with reduced rates of anastomotic leakage after elective colorectal surgery. On the contrary, there is evidence that this intervention may be associated with an increased rate of anastomotic leakage and wound complications. It is not possible to be conclusion on the latter issue because of the clinical heterogeneity of trial inclusion criteria, methodological inadequacies in trial (in particular, poor reporting of concealment and allocation), potential performance biases, and failure of intention-to-treat analyses. Nevertheless, the dogma that mechanical bowel preparation is necessary before elective colorectal surgery should be reconsidered.

Review Meta AnalysisBenzodiazepines alone or in combination with antipsychotic drugs for acute psychosis.
Acute psychotic illness, especially when associated with agitated or violent behaviour, can require urgent pharmacological tranquillisation or sedation. In several countries, clinicians often use benzodiazepines (either alone or in combination with antipsychotics) for this outcome. ⋯ There is insufficient data from these studies to support or refute the use of benzodiazepines with or without antipsychotics where emergency drugs are needed. The sole use of older antipsychotics unaccompanied by anticholinergic drugs may be problematic, but studies in this review are not large enough to identify any serious adverse effects of benzodiazepines such as respiratory depression. Larger, more informative studies are needed before definite conclusions can be drawn as to the efficacy of benzodiazapines.

Review Meta AnalysisPositioning for acute respiratory distress in hospitalised infants and children.
Because of the association between prone positioning and sudden infant death syndrome SIDS) it is recommended that young infants be placed on their backs (supine). However, the supine position might not be the most appropriate position for infants and children hospitalised with acute respiratory distress. Positioning patients has been proposed as a non-invasive way of increasing oxygenation in adult patients with acute respiratory distress. But, because of substantial differences in respiratory mechanics between adults and children and the risk of SIDS in young infants, a specific review of positioning for infants and young children with acute respiratory distress is warranted. ⋯ The prone position was significantly superior to the supine position in terms of oxygenation. However, as most patients included in the meta-analysis were ventilated, preterm infants the benefits of prone positioning may be most relevant to these infants. In addition, although placing infants and children in the prone position may improve respiratory function, the association of sudden infant death with prone positioning means that infants should only be placed in this position if continuous cardiorespiratory monitoring is used.

Review Meta AnalysisMedicinal and injection therapies for mechanical neck disorders.
Medicinal therapies and injections are commonly recommended for neck pain, yet controversy persists over their effectiveness. ⋯ Intra-muscular injection of lidocaine for chronic MND and intravenous injection of methylprednisolone for acute whiplash were effective treatments. There was limited evidence of effectiveness of epidural injection of methylprednisolone and lidocaine for chronic MND with radicular findings. Oral psychotropic agents had mixed results. There was moderate evidence that Botox A intramuscular injections for chronic MND were no better than saline. Other medications, including NSAIDs, had contradictory or limited evidence of effectiveness.

Review Meta AnalysisEndovascular coiling versus neurosurgical clipping for patients with aneurysmal subarachnoid haemorrhage.
Patients who have had an aneurysmal subarachnoid haemorrhage (SAH) are at very high risk of rebleeding if the aneurysm is not treated. The standard treatment for several decades has been surgical clipping of the neck of the aneurysm. In recent years, an alternative, the introduction of detachable coils to occlude the aneurysm, has become more common. ⋯ The evidence comes mainly from one large trial. For patients in good clinical condition with ruptured aneurysms of either the anterior or posterior circulation we have firm evidence that, if the aneurysm is considered suitable for both surgical clipping and endovascular treatment, coiling is associated with a better outcome.
