Review Meta AnalysisTranscranial direct current stimulation (tDCS) for idiopathic Parkinson's disease.
Idiopathic Parkinson's disease (IPD) is a neurodegenerative disorder, with the severity of the disability usually increasing with disease duration. IPD affects patients' health-related quality of life, disability, and impairment. Current rehabilitation approaches have limited effectiveness in improving outcomes in patients with IPD, but a possible adjunct to rehabilitation might be non-invasive brain stimulation by transcranial direct current stimulation (tDCS) to modulate cortical excitability, and hence to improve these outcomes in IPD. ⋯ There is insufficient evidence to determine the effects of tDCS for reducing off time ( when the symptoms are not controlled by the medication) and on time with dyskinesia ( time that symptoms are controlled but the person still experiences involuntary muscle movements ) , and for improving health- related quality of life, disability, and impairment in patients with IPD. Evidence of very low quality indicates no difference in dropouts and adverse events between tDCS and control groups.

Review Meta AnalysisMotivational interviewing for the prevention of alcohol misuse in young adults.
Alcohol use and misuse in young people is a major risk behaviour for mortality and morbidity. Motivational interviewing (MI) is a popular technique for addressing excessive drinking in young adults. ⋯ The results of this review indicate that there are no substantive, meaningful benefits of MI interventions for preventing alcohol use, misuse or alcohol-related problems. Although we found some statistically significant effects, the effect sizes were too small, given the measurement scales used in the included studies, to be of relevance to policy or practice. Moreover, the statistically significant effects are not consistent for all misuse measures, and the quality of evidence is not strong, implying that any effects could be inflated by risk of bias.

This review is one of a series on drugs used to treat fibromyalgia. Fibromyalgia is a clinically well-defined chronic condition of unknown aetiology characterised by chronic widespread pain that often co-exists with sleep problems and fatigue affecting approximately 2% of the general population. People often report high disability levels and poor health-related quality of life (HRQoL). Drug therapy focuses on reducing key symptoms and disability, and improving HRQoL. Cannabis has been used for millennia to reduce pain and other somatic and psychological symptoms. ⋯ We found no convincing, unbiased, high quality evidence suggesting that nabilone is of value in treating people with fibromyalgia. The tolerability of nabilone was low in people with fibromyalgia.

Review Meta AnalysisPain relief for women with cervical intraepithelial neoplasia undergoing colposcopy treatment.
Pre-cancerous lesions of cervix (cervical intraepithelial neoplasia (CIN)) are usually treated with excisional or ablative procedures. In the UK, the National Health Service (NHS) cervical screening guidelines suggest that over 80% of treatments should be performed in an outpatient setting (colposcopy clinics). Furthermore, these guidelines suggest that analgesia should always be given prior to laser or excisional treatments. Currently various pain relief strategies are employed that may reduce pain during these procedures. ⋯ Based on two small trials, there was no difference in pain relief in women receiving oral analgesics compared with placebo or no treatment (MD -3.51; 95% CI -10.03 to 3.01; 129 women). We consider this evidence to be of a low to moderate quality. In routine clinical practice, intracervical injection of local anaesthetic with a vasoconstrictor (lignocaine plus adrenaline or prilocaine plus felypressin) appears to be the optimum analgesia for treatment. However, further high quality, adequately powered trials should be undertaken in order to provide the data necessary to estimate the efficacy of oral analgesics, the optimal route of administration and dose of local anaesthetics.

Review Meta AnalysisPartial breast irradiation for early breast cancer.
Breast-conserving therapy for women with breast cancer consists of local excision of the tumour (achieving clear margins) followed by radiotherapy (RT). RT is given to sterilize tumour cells that may remain after surgery to decrease the risk of local tumour recurrence. Most true recurrences occur in the same quadrant as the original tumour. Whole breast radiotherapy (WBRT) may not protect against the development of a new primary cancer developing in other quadrants of the breast. In this Cochrane review, we investigated the delivery of radiation to a limited volume of the breast around the tumour bed (partial breast irradiation (PBI)) sometimes with a shortened treatment duration (accelerated partial breast irradiation (APBI)). ⋯ It appeared that local recurrence and 'elsewhere primaries' (new primaries in the ipsilateral breast) are increased with PBI/APBI (the difference was small), but we found no evidence of detriment to other oncological outcomes. It appeared that cosmetic outcomes and some late effects were worse with PBI/APBI but its use was associated with less acute skin toxicity. The limitations of the data currently available mean that we cannot make definitive conclusions about the efficacy and safety or ways to deliver of PBI/APBI. We await completion of ongoing trials.
