Acupuncture and related techniques are promoted as a treatment for smoking cessation in the belief that they may reduce nicotine withdrawal symptoms. ⋯ There is no clear evidence that acupuncture, acupressure, laser therapy or electrostimulation are effective for smoking cessation.

Review Meta AnalysisBuprenorphine maintenance versus placebo or methadone maintenance for opioid dependence.
Buprenorphine has recently been reported to be an alternative to methadone and LAAM for maintenance treatment of opioid dependent individuals, differing results are reported concerning its relative effectiveness indicating the need for an integrative review. ⋯ Buprenorphine is an effective intervention for use in the maintenance treatment of heroin dependence, but it is not more effective than methadone at adequate dosages.

Review Meta AnalysisLaparoscopic surgery for subfertility associated with endometriosis.
Endometriosis is the presence of endometrial glands or stroma in sites other than the uterine cavity. It is variable in both its surgical appearance and clinical manifestation often with poor correlation between the two. Surgical treatment of endometriosis aims to remove visible areas of endometriosis and restore anatomy by division of adhesions. ⋯ The use of laparoscopic surgery in the treatment of minimal and mild endometriosis may improve success rates. The relevant trials have some methodological problems and further research in this area is needed.

Review Meta AnalysisDeep transverse friction massage for treating tendinitis.
Deep transverse friction massage (DTFM) is one of several physiotherapy interventions suggested for the management of tendinitis pain. ⋯ DTFM combined with other physiotherapy modalities did not show consistent benefit over the control of pain, or improvement of grip strength and functional status for patients with ITBFS or for patients with ECRT. These conclusions are limited by the small sample size of the included RCTs. No conclusions can be drawn concerning the use or non use of DTFM for the treatment of ITBFS. Future trials, utilizing specific ITBFS methods and adequate sample sizes are needed, before conclusions can be drawn regarding the specific effect of DTFM on tendinitis.

Review Meta AnalysisGinkgo biloba for cognitive impairment and dementia.
Extracts of the leaves of the maidenhair tree, Ginkgo biloba, have long been used in China as a traditional medicine for various disorders of health. A standardized extract is widely prescribed in Germany and France for the treatment of a range of conditions including memory and concentration problems, confusion, depression, anxiety, dizziness, tinnitus and headache. The mechanisms of action are thought to reflect the action of several components of the extract and include increasing blood supply by dilating blood vessels, reducing blood viscosity, modification of neurotransmitter systems, and reducing the density of oxygen free radicals. ⋯ Ginkgo biloba appears to be safe in use with no excess side effects compared with placebo. Many of the early trials used unsatisfactory methods, were small, and we cannot exclude publication bias. Overall there is promising evidence of improvement in cognition and function associated with Ginkgo. However, the three more modern trials show inconsistent results. Our view is that there is need for a large trial using modern methodology and permitting an intention-to-treat analysis to provide robust estimates of the size and mechanism of any treatment effects.
