Research has highlighted the problems for carers of people with dementia. These include the effective loss of companionship and support of a life partner, social isolation and complex financial, legal and social decision making. The burden of caring is financially, emotionally and physically significant. Studies of the effects of ways of supporting carers and reducing the burden of caring often examine a range of outcomes. Probably because of these characteristics, no formal overview of this area of service provision has been undertaken. Moreover, the term 'intervention' in relation to caregivers of people with Alzheimer's disease is open to wide variations in interpretation at the level of service provision. Interventions range from the application of 'hi-tech' computer technology for socialy isolated carers, to the formation of specialist support groups and respite services. ⋯ With the limited nature of the research evidence in mind, it is not possible to recommend either wholesale investment in caregiver support programmes or withdrawal of the same. With the addition of further studies in future updates of this review, expected in early 1999, this presently inconclusive picture may become clearer. A number of conclusions relating to future areas of research can be put forward with more conviction. Specifically, 1) Future trials need to examine interventions included in the existing knowledge base on Alzheimer's carer-supportive interventions. 2) Outcome measures used should mirror those in similar studies. 3) Outcome measures need to be clinically and 'lay' relevant. 4) Trials need to be of longer duration given the 7-10 years median life expectancy of people with Alzheimer's Disease. 5) Sample sizes need to be increased and calculated properly given the likelihood of a moderate intervention effect (if any). 7) Blinding at the outcome assessment stage needs to be a part of future basic trial designs if bias is to be avoided. 8) If reviews are to have their power increased then quality o

ReviewCirculatory volume expansion for aneurysmal subarachnoid hemorrhage.
Patients with subarachnoid haemorrhage who develop spasm of the cerebral arteries may suffer from delayed cerebral ischaemia. This may be exacerbated by reduced circulatory volume. Intravenous fluid therapy to expand the circulating volume might reduce the risk of delayed cerebral ischaemia and so reduce the risk of neurological disability. ⋯ The effects of volume expansion therapy have not been studied properly in patients with aneurysmal subarachnoid haemorrhage. At present, there is no sound evidence for or against the use of volume expansion therapy in patients with aneurysmal subarachnoid haemorrhage.

ReviewBiopsychosocial rehabilitation for upper limb repetitive strain injuries in working age adults.
Upper limb repetitive strain injury is a common problem in western countries, causing human suffering and huge economical losses. Patients with prolonged pain associated with repetitive tasks in the work place can face both psychological and physical difficulties. Different treatment programmes, physical, psychological, behavioural, social and occupational treatments have been developed and used to help these patients. ⋯ We conclude that presently there appears to be little scientific evidence for the effectiveness of biopsychosocial rehabilitation on repetitive strain injuries. As RCTs on more intensive and comprehensive biopsychosocial treatment programmes for RSI are lacking, there does not seem to be reliable data for these interventions. There is a need for high quality trials in this field.

Among women with early breast cancer, the effects of ovarian ablation on recurrence and death have been assessed by several randomised trials that now have long follow-up. ⋯ In women aged under 50 with early breast cancer, ablation of functioning ovaries significantly improves long-term survival, at least in the absence of chemotherapy. Further randomised evidence is needed on the additional effects of ovarian ablation in the presence of other adjuvant treatments, and to assess the relevance of hormone-receptor measurements.

Artemisinin derivatives may have advantages over quinoline drugs for treating severe malaria since they are fast acting and effective against quinine resistant malaria parasites. ⋯ The evidence suggests that artemisinin drugs are no worse than quinine in preventing death in severe or complicated malaria. No artemisinin derivative appears to be better than the others.
