Review Meta AnalysisInterventions for preventing weight gain after smoking cessation.
Most people who stop smoking gain weight. There are some interventions that have been designed to reduce weight gain when stopping smoking. Some smoking cessation interventions may also limit weight gain although their effect on weight has not been reviewed. ⋯ Although some pharmacotherapies tested to limit PCWG show evidence of short-term success, other problems with them and the lack of data on long-term efficacy limits their use. Weight management education only, is not effective and may reduce abstinence. Personalised weight management support may be effective and not reduce abstinence, but there are too few data to be sure. One study showed a VLCD increased abstinence but did not prevent WG in the longer term. CBT to accept WG did not limit PCWG and may not promote abstinence in the long term. Exercise interventions significantly reduced weight in the long term, but not the short term. More studies are needed to clarify whether this is an effect of treatment or a chance finding. Bupropion, fluoxetine, NRT and varenicline reduce PCWG while using the medication. Although this effect was not maintained one year after stopping smoking, the evidence is insufficient to exclude a modest long-term effect. The data are not sufficient to make strong clinical recommendations for effective programmes to prevent weight gain after cessation.

In HIV-infected adults, oral ulcers occur more frequently, last longer and produce more painful symptoms than in immunocompetent people. Oral aphthous ulcers observed during the course of HIV infection may be severe and can result in significant morbidity in these patients. Such manifestations may interfere with oral functions and alter patients' quality of life. ⋯ There is a need for well designed studies to evaluate the efficacy and safety of topical agents for the treatment of HIV related oral aphthous ulcers.

Review Meta AnalysisMuscle relaxants for pain management in rheumatoid arthritis.
Pain management is a high priority for patients with rheumatoid arthritis (RA). Muscle relaxants include drugs that reduce muscle spasm (for example benzodiazepines such as diazepam (Valium), alprazolam (Xanax), lorazepam (Ativan) and non-benzodiazepines such as metaxalone (Skelaxin) or a combination of paracetamol and orphenadrine (Muscol)) and drugs that prevent increased muscle tone (baclofen and dantrolene). Despite a paucity of evidence supporting their use, antispasmodic and antispasticity muscle relaxants have gained widespread clinical acceptance as adjuvants in the management of patients with chronic musculoskeletal pain. ⋯ Based upon the currently available evidence in patients with RA, benzodiazepines (diazepam and triazolam) do not appear to be beneficial in improving pain over 24 hours or one week. The non-benzodiazepine agent zopiclone also did not significantly reduce pain over two weeks. However, even short term muscle relaxant use (24 hours to 2 weeks) is associated with significant adverse events, predominantly drowsiness and dizziness.

Review Meta AnalysisInterventions for helping to turn term breech babies to head first presentation when using external cephalic version.
Breech presentation is associated with increased complications. Turning a breech baby to head first presentation using external cephalic version (ECV) attempts to reduce the chances of breech presentation at birth, and reduce the adverse effects of breech vaginal birth or caesarean section. Tocolytic drugs and other methods have been used in an attempt to facilitate ECV. ⋯ Betastimulants, to facilitate ECV, increased cephalic presentation in labour and birth, and reduced the caesarean section rate in both nulliparous and multiparous women, but there were insufficient data on adverse effects. Calcium channel blockers and nitric acid donors had insufficient data to provide good evidence. At present we recommend betamimetics for facilitating ECV.There is scope for further research. The possible benefits of tocolysis to reduce the force required for successful version and the possible risks of maternal cardiovascular side effects, need to be addressed further. Further trials are needed to compare the effectiveness of routine versus selective use of tocolysis, the role of regional analgesia, fetal acoustic stimulation, amnioinfusion and the effect of intravenous or oral hydration prior to ECV.Although randomised trials of nitroglycerine are small, the results are sufficiently negative to discourage further trials.

ReviewPain management for inflammatory arthritis (rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis and other spondylarthritis) and gastrointestinal or liver comorbidity.
Even with optimal disease-modifying treatment and good control of disease activity, persistent pain due to structural damage is common in people with inflammatory arthritis and therefore additional treatment for pain might be required. Because comorbidity is highly prevalent in people with inflammatory arthritis, it is important to consider comorbidities such as gastrointestinal or liver diseases in deciding upon optimal pharmacologic pain therapy. ⋯ On the basis of the current review, there is scant evidence to guide clinicians about how gastrointestinal or liver comorbidities should influence the choice of pain treatment in patients with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis or other spondylarthritis. Based upon additional studies that included a mixed population of participants with a range of rheumatic conditions, NSAIDs should be used cautiously in patients with inflammatory arthritis and a history of gastrointestinaI comorbidity as there is consistent evidence that they may be at increased risk.
