Meta-Analysis Review
BACKGROUND
A significant proportion of electroconvulsive therapy (ECT)-treated patients experience anxiety anticipating the treatment, often to such an extent that they refuse or discontinue a much-needed treatment. Despite its great impact on treatment adherence, anxiety in patients receiving ECT is underexposed in the scientific literature.
OBJECTIVES
We aimed to review the prevalence and specific subjects of ECT-related anxiety and therapeutic interventions to reduce it.
METHODS
We performed a computerized search (EMBASE, MEDLINE, and PsycINFO) for articles meeting the following inclusion criteria: (1) qualitative (interview) studies, quantitative (questionnaire) studies, or experimental (interventional) studies that (2) report on anxiety that is related to a planned, ongoing, or past ECT treatment.
RESULTS
Of 1160 search results, 31 articles were included. Electroconvulsive therapy-related anxiety is estimated to be present in 14% to 75% of patients and is most often linked to worries about memory impairment or brain damage. Only a few interventions (chlorpromazine, meprobamate, propofol, a talking-through technique, an information leaflet, and animal-assisted therapy) have been proposed to reduce patients' ECT-related anxiety.
CONCLUSIONS
Electroconvulsive therapy-related anxiety is a highly prevalent phenomenon, and the literature provides little guidance for its clinical management. Most studies are of a low methodological quality and suffer from significant limitations, thereby hampering generalized conclusions. Given the clinical importance of ECT-related anxiety, further study on its nature and evolution through the course of treatment and on anxiety-reducing interventions is warranted.

Meta-Analysis Review
BACKGROUND
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.
OBJECTIVES
The aim of this review was to determine the efficacy and safety of muscle relaxants in pain management in patients with RA. The muscle relaxants that were included in this review are the antispasmodic benzodiazepines (alprazolam, bromazepam, chlordiazepoxide,cinolazepam, clonazepam, cloxazolam, clorazepate, diazepam, estazolam, flunitrazepam, flurazepam, flutoprazepam, halazepam, ketazolam, loprazolam, lorazepam, lormetazepam, medazepam, midazolam, nimetazepam, nitrazepam, nordazepam, oxazepam, pinazepam, prazepam, quazepam, temazepam, tetrazepam, triazolam), antispasmodic non-benzodiazepines (cyclobenzaprine, carisoprodol, chlorzoxazone, meprobamate, methocarbamol, metaxalone, orphenadrine, tizanidine and zopiclone), and antispasticity drugs (baclofen and dantrolene sodium).
SEARCH METHODS
We performed a search of the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 4th quarter 2010), MEDLINE (1950 to week 1 November 2010), EMBASE (Week 44 2010), and PsycINFO (1806 to week 2 November 2010). We also searched the 2008 to 2009 American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR) abstracts and performed a handsearch of reference lists of relevant articles.
SELECTION CRITERIA
We included randomised controlled trials which compared a muscle relaxant to another therapy (active, including non-pharmacological therapies, or placebo) in adult patients with RA and that reported at least one clinically relevant outcome.
DATA COLLECTION AND ANALYSIS
Two blinded review authors independently extracted data and assessed the risk of bias in the trials. Meta-analyses were used to examine the efficacy of muscle relaxants on pain, depression, sleep and function, as well as their safety.
MAIN RESULTS
Six trials (126 participants) were included in this review. All trials were rated at high risk of bias. Five cross-over trials evaluated a benzodiazepine, four assessed diazepam (n = 71) and one assessed triazolam (n = 15). The sixth trial assessed zopiclone (a non-benzodiazepine) (n = 40) and was a parallel group study. No trial duration was longer than two weeks while three single dose trials assessed outcomes at 24 hours only. Overall the included trials failed to find evidence of a beneficial effect of muscle relaxants over placebo, alone (at 24 hrs, 1 or 2 weeks) or in addition to non-steroidal anti-inflammatory drugs (NSAIDs) (at 24 hrs), on pain intensity, function, or quality of life. Data from two trials of longer than 24 hours duration (n = 74) (diazepam and zopiclone) found that participants who received a muscle relaxant had significantly more adverse events compared with those who received placebo (number needed to harm (NNTH) 3, 95% CI 2 to 7). These were predominantly central nervous system side effects, including dizziness and drowsiness (NNTH 3, 95% CI 2 to 11).
AUTHORS' CONCLUSIONS
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
BACKGROUND
There are two reasons to believe anxiolytics might help in smoking cessation. Anxiety may be a symptom of nicotine withdrawal. Second, smoking appears to be due, in part, to deficits in dopamine, serotonin and norepinephrine, all of which are increased by anxiolytics and antidepressants.
OBJECTIVES
The aim of this review is to assess the effectiveness of anxiolytic drugs in aiding long term smoking cessation. The drugs include buspirone; diazepam; doxepin; meprobamate; ondansetron; and the beta-blockers metoprolol, oxprenolol and propanolol.
SEARCH STRATEGY
We searched the Cochrane Tobacco Addiction Group trials register which includes trials indexed in Medline, Embase, SciSearch and PsycLit, and meetings abstracts.
SELECTION CRITERIA
We considered randomized trials comparing anxiolytic drugs to placebo or an alternative therapeutic control for smoking cessation. We excluded trials with less than 6 months follow-up.
DATA COLLECTION AND ANALYSIS
We extracted data in duplicate on the type of study population, the nature of the drug therapy, the outcome measures, method of randomisation, and completeness of follow-up. The main outcome measure was abstinence from smoking after at least six months follow-up in patients smoking at baseline. We used the most rigorous definition of abstinence for each trial, and biochemically validated rates if available. Where appropriate, we performed meta-analysis using a fixed effects model.
MAIN RESULTS
There was one trial each of the anxiolytics diazepam, meprobamate, metoprolol and oxprenolol. There were two trials of the anxiolytic buspirone. None of the trials showed strong evidence of an effect for any of these drugs in helping smokers to quit. However, confidence intervals were wide, and an effect of anxiolytics cannot be ruled out on current evidence.
REVIEWER'S CONCLUSIONS
There is no consistent evidence that anxiolytics aid smoking cessation, but the available evidence does not rule out a possible effect.

Review
BACKGROUND
Enuresis (bedwetting) is a socially unacceptable and stressful condition which affects around 15-20% of five year olds, and up to 2% of young adults. Although there is a high rate of spontaneous remission, the social, emotional and psychological costs to the children can be great.
OBJECTIVES
To assess the effects of drugs other than desmopressin and tricyclics on nocturnal enuresis in children, and to compare them with other interventions.
SEARCH STRATEGY
The following electronic databases were searched: MEDLINE to June 1997; AMED; ASSIA; BIDS; BIOSIS Previews (1985-1996); CINAHL; DHSS Data; EMBASE (1974 to June 1997); PsycLIT and SIGLE. Organisations, manufacturers, researchers and health professionals concerned with enuresis were contacted for information. The reference sections of obtained studies were also checked for further trials. Date of the most recent search: July 1997.
SELECTION CRITERIA
All randomised trials of drugs (excluding desmopressin or tricyclics) for nocturnal enuresis in children were included in the review. Trials were eligible for inclusion if: children were randomised to receive drugs compared with placebo, other drugs or other conservative interventions for nocturnal bedwetting; participants with organic causes for their bedwetting were excluded; and baseline assessments of the level of bedwetting were provided. Trials focused solely on daytime wetting were excluded.
DATA COLLECTION AND ANALYSIS
Two reviewers independently assessed the quality of the eligible trials, and extracted data.
MAIN RESULTS
None of the drugs (phenmetrazine, amphetamine sulphate/ephedrine + atropine, furosemide (sic) or chlorprotixine) were better than placebo during treatment. The numbers were too small to draw reliable conclusions, and none are used in current practice in the UK. Imipramine (a tricyclic) was better than each of the three drugs with which it was compared (meprobamate, ephedrine sulphate and furosemide) even though the numbers were small. Alarm treatment was better than drugs in one small trial.
REVIEWER'S CONCLUSIONS
There was not enough evidence to suggest that the included drugs reduced bedwetting. There was limited evidence to suggest that imipramine and alarms were better, and in other reviews, desmopressin, tricyclics and alarm interventions have tentatively been shown to be effective.

Review
BACKGROUND
There are two reasons to believe antidepressants and anxiolytics might help in smoking. First, anxiety and depression are symptoms of nicotine withdrawal, and smoking cessation sometimes precipitates depression. Second, smoking appears to be due, in part, to deficits in dopamine, serotonin and norepinephrine, all of which are increased by anxiolytics and antidepressants.
OBJECTIVES
The aim of this review is to assess the effectiveness of such drugs in aiding long term smoking cessation. The drugs include bupropion; buspirone; diazepam; doxepin; fluoxetine; imipramine; meprobamate; moclobemide; nortriptyline; tryptophan; ondansetron; venlafaxine and the beta-blockers metoprolol, oxprenolol and propanolol.
SEARCH STRATEGY
We searched the Cochrane Tobacco Addiction Group trials register which includes trials indexed in Medline, Embase, SciSearch and PsycLit, and meetings abstracts.
SELECTION CRITERIA
We considered randomized trials comparing anxiolytic or antidepressant drugs to placebo or an alternative therapeutic control for smoking cessation. We excluded trials with less than 6 months follow-up.
DATA COLLECTION AND ANALYSIS
We extracted data in duplicate on the type of study population, the nature of the drug therapy, the outcome measures, method of randomisation, and completeness of follow-up. The main outcome measure was abstinence from smoking after at least six months follow-up in patients smoking at baseline. We used the most rigorous definition of abstinence for each trial, and biochemically validated rates if available. Where appropriate, we performed meta-analysis using a fixed effects model.
MAIN RESULTS
There was one trial each of the anxiolytics diazepam, meprobamate, metoprolol and oxprenolol. There were two trials of the anxiolytic buspirone. None of these showed evidence of effectiveness in helping smokers to quit. There was one trial each of the antidepressants fluoxetine and moclobemide, two of nortriptyline, and four trials of bupropion. Nortriptyline and bupropion increased cessation and other antidepressants might also be effective. One trial found combined bupropion and nicotine patch produced higher quit rates than patch alone.
REVIEWER'S CONCLUSIONS
There is little evidence that anxiolytics aid smoking cessation. Some antidepressants (bupropion and nortriptyline) can aid smoking cessation. It is not clear whether these effects are specific for individual drugs, or a class effect.
