Review Meta AnalysisDesferrioxamine mesylate for managing transfusional iron overload in people with transfusion-dependent thalassaemia.
Thalassaemia major is a genetic disease characterised by a reduced ability to produce haemoglobin. Management of the resulting anaemia is through transfusions of red blood cells. Repeated transfusions results in excessive accumulation of iron in the body (iron overload), removal of which is achieved through iron chelation therapy. Desferrioxamine is the most widely used iron chelator. Substantial data have shown the beneficial effects of desferrioxamine. However, important questions exist about whether desferrioxamine is the best schedule for iron chelation therapy. ⋯ We found no reason to change current treatment recommendations. However, considerable uncertainty continues to exist about the optimal schedule for desferrioxamine in people with transfusion-dependent thalassaemia.

No intervention has proven effective in modifying long-term disease prognosis in Multiple Sclerosis (MS) but exercise therapy is considered to be an important part of symptomatic and supportive treatment for these patients. ⋯ The results of the present review suggest that exercise therapy can be beneficial for patients with MS not experiencing an exacerbation. There is an urgent need for consensus on a core set of outcome measures to be used in exercise trials. In addition, these studies should experimentally control for 'dose' of treatment, type of MS and should include sufficient contrast between experimental and control groups.

Adalimumab is a fully human anti-TNFalpha monoclonal antibody. Published studies indicate that its use in patients with RA can be effective and safe. ⋯ On the basis of the studies reviewed here, adalimumab in combination with methotrexate is efficacious and safe in the treatment of the rheumatoid arthritis. Adalimumab 40 mg sc e.o.w. and 20 mg e.w. slows the radiographic progression at 52 weeks. Adalimumab in combination with DMARDs other than methotrexate is also efficacious and safe, even though data from one only study are available and the number of patients in each group is low. Adalimumab in monotherapy is efficacious and safe in the treatment of the rheumatoid arthritis but the effect size is lower than with combined therapy.

Review Meta AnalysisHaloperidol plus promethazine for psychosis induced aggression.
Health services often manage agitated or violent people and for emergency psychiatric services such behaviour is particularly prevalent (10%). The drugs used in this situation should ensure that the person swiftly and safely becomes calm. ⋯ This review suggests that both benzodiazepines work, but that midazolam has a faster onset and thereby reduces the risk of exposure to violence. Both benzodiazepines have the potential to cause respiratory depression, probably midazolam more so than lorazepam, and we would question the use of this group of drugs outside of those services fully confident of observing for and managing the consequences of respiratory distress. Most evidence, however, exists for the haloperidol plus promethazine mix, with currently more than 400 people randomised to the combination. The onset of action is swift and faster than lorazepam. The combination also seems safe with no clear longer term consequences. We would expect policy makers recommending other drug managements to have equally compelling evidence to support their guidance and hope that this would not be founded in conjecture or consensus, which may be more difficult to defend than evidence from high quality studies.

Patients with unicompartmental osteoarthritis of the knee can be treated with a correction osteotomy. The goal of the correction osteotomy is to transfer the load bearing from the pathologic to the normal compartment of the knee. A successful outcome of the osteotomy relies on proper patient selection, stage of osteoarthritis, achievement and maintenance of adequate operative correction. ⋯ Based on 11 studies, of which 6 were high quality, we conclude that there is silver level evidence that valgus HTO improves knee function and reduces pain. There is no evidence whether an osteotomy is more effective than conservative treatment and the results so far do not justify a conclusion about effectiveness of specific surgical techniques.
