Review Comparative StudyIntrarectal quinine versus intravenous or intramuscular quinine for treating Plasmodium falciparum malaria.
In children with falciparum malaria, a proprietary quinine preparation (adjusted to make it less acidic) administered rectally may be easier to use and less painful than intramuscular or intravenous administration. However, rectal quinine may be less effective. ⋯ We detected no difference in the effect on parasites and clinical illness for intrarectal quinine, but most trials were small. Pain may be less with intrarectal proprietary, buffered quinine preparations (made less acidic by adjustment of the pH to 4.5). Further larger trials in patients with severe malaria and in adults are required before the intrarectal route can be recommended.

Hypothermia has been used in the treatment of head injury for many years. Encouraging results from small trials and laboratory studies led to renewed interest in the area and some larger trials. ⋯ Hypothermia may be effective in reducing death and unfavourable outcomes for traumatic head injured patients, but significant benefit was only found in low quality trials. Low quality trials have a tendency to overestimate the treatment effect. The high quality trials found some statistically non-significant benefit of hypothermia which could be due to the play of chance. Hypothermia may increase the risk of pneumonia. Due to uncertainties in its effects, hypothermia should only be given to patients taking part in a randomised controlled trial with good allocation concealment.

Review Meta AnalysisSingle dose oral paracetamol (acetaminophen) with codeine for postoperative pain in adults.
This is an updated version of the Cochrane review published in Issue 4, 1998. Combining drugs from different classes with different modes of action may offer opportunity to optimise efficacy and tolerability, using lower doses of each drug to achieve the same degree of pain relief. Previously we concluded that addition of codeine to paracetamol provided additional pain relief, but at expense of additional adverse events. New studies have been published since. This review sought to evaluate efficacy and safety of paracetamol plus codeine using current data, and compare findings with other analgesics evaluated similarly. ⋯ This update confirms previous findings that combining paracetamol with codeine provided clinically useful levels of pain relief in about 50% of patients with moderate to severe postoperative pain, compared with under 20% with placebo. New information for remedication shows that the combination extended the duration of analgesia by about one hour compared to treatment with the same dose of paracetamol alone. At higher doses, more participants experienced adequate pain relief, but the amount of information available for the 1000 mg paracetamol plus 60 mg codeine dose was small, and based on limited information.

Review Meta AnalysisOn-site mental health workers delivering psychological therapy and psychosocial interventions to patients in primary care: effects on the professional practice of primary care providers.
Mental health problems are common in primary care and mental health workers (MHWs) are increasingly working in this setting delivering psychological therapy and psychosocial interventions to patients. In addition to treating patients directly, the introduction of on-site MHWs represents an organisational change that may lead to changes in the clinical behaviour of primary care providers (PCPs). ⋯ This review provides some evidence that MHWs working in primary care to deliver psychological therapy and psychosocial interventions cause a significant reduction in PCP behaviours such as consultations, prescribing, and referrals to specialist care. However, the changes are modest in magnitude, inconsistent, do not generalise to the wider patient population, and their clinical or economic significance is unclear.

Review Meta AnalysisTransmyocardial laser revascularization versus medical therapy for refractory angina.
Chronic angina and advanced forms of coronary disease are increasingly more frequent. Although the improved efficacy of available revascularization treatments, a subgroup of patients present with refractory angina. Transmyocardial laser revascularization (TMLR) has been proposed to improve the clinical situation of these patients. ⋯ There is insufficient evidence to conclude that the clinical benefits of TMLR outweigh the potential risks. The procedure is associated with a significant early mortality.
