Review Meta AnalysisErgonomic and physiotherapeutic interventions for treating upper extremity work related disorders in adults.
Conservative interventions such as physiotherapy and ergonomic adjustments play a major part in the treatment of most work-related musculoskeletal disorders (WRMD). ⋯ This review shows limited evidence for the effectiveness of keyboards with an alternative force-displacement of the keys or an alternative geometry, and limited evidence for the effectiveness of individual exercises. The benefit of expensive ergonomic interventions (such as new chairs, new desks etc) in the workplace is not clearly demonstrated.

Review Meta AnalysisErythropoietin for patients with malignant disease.
Anaemia associated with cancer and cancer therapy is an important clinical factor in the treatment of malignant diseases. Therapeutic alternatives are recombinant human erythropoietin (EPO) and red blood cell transfusions. ⋯ There is consistent evidence that the administration of erythropoietin reduces the risk for blood transfusions and the number of units transfused in cancer patients. For patients with baseline haemoglobin below 10 g/dL there is strong evidence that erythropoietin improves haematological response. There is inconclusive evidence whether erythropoietin improves tumour response and overall survival. Research on side effects is inconclusive.

ReviewPin site care for preventing infections associated with external bone fixators and pins.
Metal pins are used to apply skeletal traction or external fixation devices in the management of orthopaedic fractures. These pins protrude through the skin and are therefore described as 'percutaneous' and much has been written on the management of the associated skin wound. The way in which percutaneous pins are treated may affect the incidence of pin site infection. Recommendations for care are not necessarily evidence based. This review set out to summarise the research evidence on the effect of pin site care on infection rates. ⋯ There is very little evidence as to which pin site care regimen best reduces infection rates. Clearly there is a need for large RCTs to determine the best method of pin site management.

ReviewInterventions for replacing missing teeth: maintaining health around dental implants.
To maintain healthy tissues around dental implants it is important to institute an effective preventive regimen (supportive therapy). Different maintenance regimens have been suggested, however it is unclear which are the most effective. ⋯ There is only little reliable evidence for which are the most effective interventions for maintaining health around peri-implant tissues. There was no evidence that the use of powered or sonic toothbrushes was superior to manual toothbrushing. There is weak evidence that Listerine mouthwash, used twice a day for 30 seconds, as adjunct to routine oral hygiene is effective in reducing plaque formation and marginal bleeding around implants. There was no evidence that phosphoric etching gel offered any clinical advantage over mechanical debridement. These findings are based on RCTs having short follow-up periods and few subjects. There is not any reliable evidence for the most effective regimens for long term maintenance. More RCTs should be conducted in this area. In particular, there is a definite need for trials powered to find possible differences, using primary outcome measures and with much longer follow up. Such trials should be reported according the CONSORT guidelines (http://www.consort-statement.org/).

Pressure ulcers (also known as bedsores, pressure sores, decubitus ulcers) are areas of localised damage to the skin and underlying tissue due to pressure, shear or friction. They are common in the elderly and immobile and costly in financial and human terms. Pressure-relieving beds, mattresses and seat cushions are widely used as aids to prevention in both institutional and non-institutional settings. ⋯ In people at high risk of pressure ulcer development, consideration should be given to the use of higher specification foam mattresses rather than standard hospital foam mattresses. The relative merits of higher-tech constant low pressure and alternating pressure for prevention are unclear. Organisations might consider the use of pressure relief for high risk patients in the operating theatre, as this is associated with a reduction in post-operative incidence of pressure ulcers. Seat cushions and overlays designed for use in Accident & Emergency settings have not been adequately evaluated.
