Review Meta AnalysisTopical NSAIDs for chronic musculoskeletal pain in adults.
Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly taken orally, but they are also available in topical preparations to be applied to or rubbed onto the skin of a painful joint, typically one affected by arthritis, with the aim of relieving pain locally. Topical NSAIDs are widely used in some parts of the world for acute and chronic painful conditions, but have not been universally accepted until recently. One of the problems has been that older clinical studies were generally short, lasting four weeks or less, and short duration studies are not regarded as adequate in ongoing painful conditions. ⋯ Topical NSAIDs can provide good levels of pain relief; topical diclofenac solution is equivalent to that of oral NSAIDs in knee and hand osteoarthritis, but there is no evidence for other chronic painful conditions. Formulation can influence efficacy. The incidence of local adverse events is increased with topical NSAIDs, but gastrointestinal adverse events are reduced compared with oral NSAIDs.

Although conventional non-pharmacological and pharmacological treatments for insomnia are effective in many people, alternative therapies such as acupuncture are widely practised. However, it remains unclear whether current evidence is rigorous enough to support acupuncture for the treatment of insomnia. ⋯ Due to poor methodological quality, high levels of heterogeneity and publication bias, the current evidence is not sufficiently rigorous to support or refute acupuncture for treating insomnia. Larger high-quality clinical trials are required.

The prevalence of mechanical neck disorders (MND) is known to be both a hindrance to individuals and costly to society. As such, massage is widely used as a form of treatment for MND. ⋯ No recommendations for practice can be made at this time because the effectiveness of massage for neck pain remains uncertain.As a stand-alone treatment, massage for MND was found to provide an immediate or short-term effectiveness or both in pain and tenderness. Additionally, future research is needed in order to assess the long-term effects of treatment and treatments provided on more than one occasion.

Review Meta AnalysisPerioperative glycaemic control for diabetic patients undergoing surgery.
Patients with diabetes mellitus are at increased risk of postoperative complications. Data from randomised clinical trials and meta-analyses point to a potential benefit of intensive glycaemic control, targeting near-normal blood glucose, in patients with hyperglycaemia (with and without diabetes mellitus) being submitted to surgical procedures. However, there is limited evidence concerning this question in patients with diabetes mellitus undergoing surgery. ⋯ The included trials did not demonstrate significant differences for most of the outcomes when targeting intensive perioperative glycaemic control compared with conventional glycaemic control in patients with diabetes mellitus. However, posthoc analysis indicated that intensive glycaemic control was associated with an increased number of patients experiencing hypoglycaemic episodes. Intensive glycaemic control protocols with near-normal blood glucose targets for patients with diabetes mellitus undergoing surgical procedures are currently not supported by an adequate scientific basis. We suggest that insulin treatment regimens, patient- and health-system relevant outcomes, and time points for outcome measures should be defined in a thorough and uniform way in future studies.

ReviewTransarterial (chemo)embolisation versus no intervention or placebo intervention for liver metastases.
Primary liver tumours and liver metastases from colorectal carcinoma are the two most common malignant tumours to affect the liver. The liver is second only to the lymph nodes as the most common site for metastatic disease. More than half of the patients with metastatic liver disease will die from metastatic complications. Chemoembolisation is based on the concept that the blood supply to hepatic tumours originates predominantly from the hepatic artery. Therefore, embolisation of the hepatic artery can lead to selective necrosis of the liver tumour while it may leave normal parenchyma virtually unaffected. ⋯ On the basis of one small randomised trial that did not describe sequence generation, allocation concealment or blinding, it can be concluded that in patients with liver metastases no significant survival benefit or benefit on extrahepatic recurrence was found in the embolisation group in comparison with the palliation group. The probability for selective outcome reporting bias in the trial is high. At present, transarterial (chemo)embolisation cannot be recommended outside randomised clinical trials.
