Eletriptan (Relpax) is a new triptan soon to be made available by prescription for the treatment of acute migraine. Currently five triptans are available by prescription and more are under development. In light of the many drugs for treating acute migraine, there is a need for evidence-based assessments to help determine the relative efficacy and harm of these treatments. ⋯ Eletriptan 20 mg, 40 mg and 80 mg are effective for the treatment of an acute migraine attack. Effectiveness is dose-related, with statistically significant differences between doses for pain-free response and 24-hour outcomes. Eletriptan compares well with other triptans available for outcomes measured up to 2 hours and provides meaningful relief for 24 hours. Taken as a single dose, eletriptan was well tolerated and caused no major harm. The incidence of minor harm was dose-dependent, with 80 mg giving significantly more adverse effects than 40 mg.

ReviewEducation interventions for adults who attend the emergency room for acute asthma.
The use of educational and behavioural interventions in the management of chronic asthma have a strong evidence base. There may be a role for educative interventions following presentation in an emergency setting in adults. ⋯ This review found that educational interventions applied in the emergency department reduce subsequent asthma admissions to hospital. The interventions did not significantly reduce ED re-presentations; while the trend in effect favours educational interventions, the pooled results were not statistically significant. The impact of educational intervention in this context on longer term outcomes relating to asthma morbidity is unclear. Priorities for additional research in this area include assessment of health-related quality of life, lung function assessment, exploration of the relationship between socio-economic status and asthma morbidity, and better description of the intervention assessed.

Reality Orientation (RO) was first described as a technique to improve the quality of life of confused elderly people, although its origins lie in an attempt to rehabilitate severely disturbed war veterans, not in geriatric work. It operates through the presentation of orientation information (eg time, place and person-related) which is thought to provide the person with a greater understanding of their surroundings, possibly resulting in an improved sense of control and self-esteem. There has been criticism of RO in clinical practice, with some fear that it has been applied in a mechanical fashion and has been insensitive to the needs of the individual. There is also a suggestion that constant relearning of material can actually contribute to mood and self-esteem problems. There is often little consistent application of psychological therapies in dementia services, so a systematic review of the available evidence is important in order to identify the effectiveness of the different therapies. Subsequently, guidelines for their use can be made on a sound evidence base. ⋯ There is some evidence that RO has benefits on both cognition and behaviour for dementia sufferers. Further research could examine which features of RO are particularly effective. It is unclear how far the benefits of RO extend after the end of treatment, but and it appears that a continued programme may be needed to sustain potential benefits.

ReviewPeriurethral injection therapy for urinary incontinence in women.
Periurethral or transurethral injection of bulking agents is a surgical procedure most often used for the treatment of stress urinary incontinence a common, troublesome symptom amongst adult women. ⋯ Despite five additional trials, this updated review is still an unsatisfactory basis for practice. The trials were small and generally of moderate quality. The only evidence of benefit comes for within-group short-term changes following injection. The finding that placebo saline injection was followed by a similar symptomatic improvement questions the mechanism of any effects. There were no trials in comparison with pelvic floor muscle training -the obvious non-surgical comparator. Greater symptomatic improvement was observed after surgery, although these advantages need to be set against likely higher risks. No clear-cut conclusions could be drawn from trials comparing alternative agents; one small trial suggests that periurethral injection may carry more risks than transurethral injection. The single trial of autologous fat provides a reminder that periurethral injections can occasionally cause serious side-effects. Pending further evidence, injection therapy may represent a useful option for short-term symptomatic relief amongst selected women with co-morbidity that precludes anaesthesia - two or three injections are likely to be required to achieve a satisfactory result.

Many patients visit their general practitioner (GP) because of problems that are psychosocial in origin. However, for many of these problems there is no evidence-based treatment available in primary care, and these patients place time-consuming demands on their GP. Therefore, GPs could benefit from tools to help these patients more effectively and efficiently. In this light, it is important to assess whether structured psychosocial interventions might be an appropriate tool for GPs. Previous reviews have shown that psychosocial interventions in primary care seem more effective than usual care. However, these interventions were mostly performed by health professionals other than the GP. ⋯ In general, there is little available evidence on the use of psychosocial interventions by general practitioners. Of the psychosocial interventions reviewed, problem-solving treatment for depression may offer promise, although a stronger evidence-base is required and the effectiveness in routine practice remains to be demonstrated. More research is required to improve the evidence-base on this subject.
