Review Meta AnalysisTherapy-based rehabilitation services for stroke patients at home.
Stroke Unit care is now accepted as an effective service model for hospital care, but the effectiveness of outpatient care is less certain. This review focuses on therapy-based rehabilitation services targeted at stroke patients living at home. ⋯ Therapy-based rehabilitation services targeted towards stroke patients living at home appear to improve independence in personal activities of daily living. However, the evidence is derived from a review of heterogeneous interventions and therefore further exploration of the interventions is justifiable.

ReviewTransient neurologic symptoms (TNS) following spinal anaesthesia with lidocaine versus other local anaesthetics.
Spinal anaesthesia has been in use since the turn of the late 19th century. The most serious complication of this technique is damage to the spinal cord or nerve roots resulting in lasting neurologic sequelae. Such serious adverse effects seldom happen. There has been an increase in the number of reports during the last nine years implicating lidocaine as a possible cause of temporary and permanent neurologic complications after spinal anaesthesia. Follow-up of patients who received uncomplicated spinal anaesthesia revealed that some of them developed pain in the lower extremities after an initial full recovery. This painful condition that occurs in the immediate post-operative period was named "transient neurologic symptoms" (TNS). ⋯ The risk of developing TNS after spinal anaesthesia with lidocaine was significantly higher than when bupivacaine, prilocaine and procaine were used. The term "TNS", which implies a positive neurologic finding, should not be used for this painful condition, which is in fact comparable to another common adverse effect after spinal anaesthesia - lower back pain. How much the pain in the lower extremities influences patient satisfaction is not elucidated clearly in the literature.

Review Meta AnalysisVaccines for preventing pneumococcal infection in adults.
Diseases caused by Streptococcus pneumoniae (S. pneumoniae) continue to cause substantial morbidity and mortality throughout the world. Polysaccharide pneumococcal vaccines have been developed for over 50 years and may have the potential to prevent disease and death. ⋯ While polysaccharide pneumococcal vaccines do not appear to reduce the incidence of pneumonia or death in adults with or without chronic illness, or in the elderly (55 years and above), the evidence from non-randomised studies suggests that the vaccines are effective in the reducing the incidence of the more specific outcome, invasive pneumococcal disease, among adults and the immunocompetent elderly (55 years and above). Surveillance data suggest that infection rates vary widely between and also within countries, but a typical figure in developed countries is 0.01%, or 10 per 100,000 per year. Efficacy of 50% then corresponds to a number-needed-to-treat (NNT) of 20,000 vaccinations per infection avoided, and perhaps 50,000 per death avoided.

Review Meta AnalysisCorticosteroids for hospitalised children with acute asthma.
Systemic corticosteroids are used routinely in the management of children with severe acute asthma. There is a lack of consensus regarding the agent, dose and route of corticosteroid administration. ⋯ Systemic corticosteroids produce some improvements for children admitted to hospital with acute asthma. The benefits may include earlier discharge and fewer relapses. Inhaled or nebulised corticosteroids cannot be recommended as equivalent to systemic steroids at this time. Further studies examining differing doses and routes of administration for corticosteroids will clarify the optimal therapy.

Benign prostatic hyperplasia (BPH) is a nonmalignant enlargement of the prostate which can result in bothersome lower urinary tract symptoms. The treatment goal for men with BPH is to relieve these bothersome symptoms. ⋯ Tamsulosin provided a small to moderate improvement in urinary symptoms and flow compared to men receiving placebo in men with BPH. Effectiveness was similar to other alpha antagonists and increased only slightly with higher doses. Long term effectiveness and ability to reduce complications due to BPH progression could not be determined. Adverse effects were generally mild but their frequency, including withdrawals, increased substantially with the higher doses that are generally available for treatment.
