Review Meta AnalysisAntipsychotics for acute and chronic pain in adults.
The role of antipsychotics as adjuvant analgesics is a subject of longstanding controversy. Neuroleptanalgesia (i.e. a state of quiescence, altered awareness, and analgesia produced by a combination of taking an opioid analgesic and an antipsychotic), an established term for the management of acute pain, was shown to negatively influence disease course and total mortality in unstable angina patients. Nevertheless, antipsychotics are used to treat chronic pain (e.g. chronic headache, fibromyalgia and diabetic neuropathia). With atypical antipsychotics, a new class of antipsychotics, fewer extrapyramidal side effects and additional benefits may be available. ⋯ Antipsychotics might be used as an add-on therapy in the treatment of painful conditions. Nevertheless, extrapyramidal and sedating side effects have to be considered before using antipsychotics for treating painful conditions.Results for antipsychotics in the treatment of different painful conditions are mixed and most sample sizes in the reviewed RCTs are small. Further studies on atypical antipsychotics in larger double-blind placebo-controlled studies including standardised pain assessment/documentation are warranted.

Review Meta AnalysisCombined intermittent pneumatic leg compression and pharmacological prophylaxis for prevention of venous thromboembolism in high-risk patients.
It has been suggested that combined modalities (methods of treatment) are more effective than single modalities in preventing venous thromboembolism (defined as deep vein thrombosis and pulmonary embolism, or both) in high-risk patients. ⋯ Compared with compression alone, combined prophylactic modalities decrease significantly the incidence of venous thromboembolism. Compared with pharmacological prophylaxis alone, combined modalities reduce significantly the incidence of DVT but the effect on PE is unknown. The results of the current review support, especially in high-risk patients, the use of combined modalities. More studies on their role in PE prevention, compared with pharmacological prophylaxis alone, are urgently needed.

Review Meta AnalysisCorticosteroids for the prevention and treatment of post-extubation stridor in neonates, children and adults.
Post-extubation stridor may prolong length of stay in the intensive care unit, particularly if airway obstruction is severe and re-intubation proves necessary. Corticosteroids, however, may be associated with adverse effects ranging from hypertension to hyperglycemia, and a more systematic assessment of the efficacy of this therapy is indicated prior to widespread adoption of this practice. ⋯ Using corticosteroids to prevent (or treat) stridor after extubation has not proven effective for neonates, children or adults. However, given the consistent trends towards benefit, this intervention does merit further study.

Review Meta AnalysisVitamin A for preventing acute lower respiratory tract infections in children up to seven years of age.
Vitamin A supplements are effective for preventing diarrhoea. There are theoretical reasons it might also be effective for acute lower respiratory tract infections (LRTIs), also very common in children, especially in low income countries. ⋯ This unexpected result is outside our current understanding of the use of vitamin A for preventing acute LRTIs. Accordingly, vitamin A should not be given to all children to prevent acute LRTIs. There is evidence for vitamin A supplements to prevent acute LRTIs in children with low serum retinol or those with a poor nutritional status.

Postpartum haemorrhage (PPH) (bleeding from the genital tract after childbirth) is a major cause of maternal mortality and disability, particularly in under-resourced areas. In these settings, poor nutrition, malaria and anaemia may aggravate the effects of PPH. In addition to the standard known strategies to prevent and treat PPH, there is a need for simple, non-expensive techniques which can be applied in low-resourced settings to prevent or treat PPH. ⋯ The present review adds support to the 2004 joint statement of the International Confederation of Midwives and the International Federation of Gynaecologists and Obstetricians on the management of the third stage of labour, that uterine massage after delivery of the placenta is advised to prevent PPH. However, due to the limitations of the one trial reviewed, trials with sufficient numbers to estimate the effects of sustained uterine massage with great precision, both with and in the absence of uterotonics, are needed.
