ReviewPramipexole for levodopa-induced complications in Parkinson's disease.
To compare the efficacy and safety of adjuvant pramipexole therapy versus inactive placebo in patients with Parkinson's disease, already established on levodopa. ⋯ Pramipexole can be used to reduce off time, improve motor impairments and disability and reduce levodopa dose at the expense of increased dyskinetic adverse events. This conclusion is based on short and medium term trials (up to 24 weeks). Further trials are required to directly compare the newer with the older dopamine agonists.

ReviewTarget payments in primary care: effects on professional practice and health care outcomes.
The method by which physicians are paid may affect their professional practice. Although payment systems may be used to achieve policy objectives (e.g. improving quality of care, cost containment and recruitment to under-served areas), little is known about the effects of different payment systems in achieving these objectives. Target payments are a payment system which remunerate professionals only if they provide a minimum level of care. ⋯ The evidence from the studies identified in this review is not of sufficient quality or power to obtain a clear answer to the question as to whether target payment remuneration provides a method of improving primary health care. Additional efforts should be directed in evaluating changes in physicians' remuneration systems. Although it would not be difficult to design a randomised controlled trial to evaluate the impact of such payment systems, it would be difficult politically to conduct such trials.

Exercise therapy is a widely used treatment for low back pain. ⋯ The evidence summarised in this systematic review does not indicate that specific exercises are effective for the treatment of acute low back pain. Exercises may be helpful for chronic low back pain patients to increase return to normal daily activities and work.

ReviewModern combined oral contraceptives for pain associated with endometriosis.
Endometriosis is a major women's health-care problem. It causes pain and/or infertility, and affects millions of women worldwide. Endometriosis is defined according to histological criteria by the presence of tissue resembling endometrium in sites outside the uterus, most commonly the ovaries and peritoneum. The aim of treatment has been to remove the deposits of ectopic endometrium that are thought to be responsible for the symptoms of endometriosis. This can be achieved surgically by destroying or removing the implants; medical therapies induce atrophy within the hormonally-dependent ectopic endometrium. The duration of hormonal treatment may be limited by unwanted side effects. There is some evidence, however, from epidemiological research that current use of the combined oral contraceptive pill (OCP) is associated with a reduced incidence of endometriosis. The combined pill has the great advantage over other hormonal treatments that it can be taken indefinitely. ⋯ There is a paucity of data relating to the use of oral contraceptive preparations in the treatment of symptomtic endometriosis. The data such as it is supports the common practice of the use of the oral contraceptive pill as a first line therapy but further research is required to fully evaluate its role in the management of endometriosis.

ReviewBotulinum toxin type A in the treatment of lower limb spasticity in cerebral palsy.
To determine whether botulinum toxin (BtA) is an effective and safe treatment for lower limb spasticity in children with cerebral palsy. Functional outcomes are of particular interest. ⋯ This systematic review has not revealed strong controlled evidence to support or refute the use of BtA for the treatment of leg spasticity in cerebral palsy. Ongoing randomised controlled trials are likely to provide useful data on the short term effects of BtA for leg spasticity. Future research should also assess the longer term use of BtA. Ideally studies should be pragmatic in their approach to dose and distribution of toxin to reflect practise. Outcome measures assessing function and disability would give the most useful information.
