Chlorpromazine, formulated in the 1950s, remains a benchmark treatment for those with schizophrenia. ⋯ This review will confirm much that clinicians and recipients of care already know but provides quantification to support clinical impression. Despite the humbling 40% improvement rate in those who were allocated to placebo, chlorpromazine's global position as the 'benchmark' treatment of those with psychoses is not threatened by this review. Chlorpromazine, in common use for nearly half a century, is a well established but imperfect treatment. Judicious use of this best available evidence should lead to better informed decisions both by carers and those with psychotic illnesses.

The majority of strokes are due to blockage of an artery in the brain by a blood clot. Clot dissolving (or thrombolytic) drugs may reduce brain damage from the stroke, but may also cause serious bleeding in the brain. Thrombolytic therapy has now been evaluated in several randomised trials in acute ischaemic stroke. ⋯ Thrombolytic therapy increases deaths within the first seven to ten days, and deaths at final follow-up. Thrombolytic therapy also significantly increases symptomatic and fatal intracranial haemorrhage. These risks are offset by a reduction in disability in survivors, so that there is, overall, a significant net reduction in the proportion of patients dead or dependent in activities of daily living. The data from trials using intravenous recombinant tissue Plasminogen Activator, from which there is the most evidence on thrombolytic therapy so far, suggest that it may be associated with less hazard and more benefit. There was heterogeneity between the trials and the optimum criteria to identify the patients most likely to benefit and least likely to be harmed, the agent, dose, and route of administration, are not clear.

ReviewAntifibrinolytic therapy for aneurysmal subarachnoid haemorrhage.
Re-bleeding is an important cause of death and disability in people with aneurysmal subarachnoid haemorrhage. This is probably due to dissolution of the clot by natural fibrinolytic activity. ⋯ Antifibrinolytic treatment does not appear to benefit people with aneurysmal subarachnoid haemorrhage. However, the trials were all done more than 10 years ago. New strategies may counteract the ischaemia-inducing potential of antifibrinolytic treatment and lead to improved outcome. A trial of combined antifibrinolytic and anti-ischaemia treatment is underway.

Despite widespread use of naltrexone maintenance in many countries for more than a decade, the evidence of its effects has not yet been systematically evaluated. ⋯ The available trials do not allow a final evaluation of naltrexone maintenance treatment yet. A trend in favour of treatment with naltrexone was observed for certain target groups (particularly people who are highly motivated), as has been previously described in the literature.

ReviewEarly emergency department treatment of acute asthma with systemic corticosteroids.
The airway edema and secretions associated with acute asthma are most effectively treated with anti-inflammatories such as corticosteroids delivered by inhaled, oral, intravenous or intra-muscular routes. There is an unresolved debate about the use of systemic corticorticoids in the early treatment of acute asthma for emergency department patients. ⋯ Use of corticosteroids within 1 hour of presentation to an ED significantly reduces the need for hospital admission in patients with acute asthma. Benefits appear greatest in patients with more severe asthma, and those not currently receiving steroids. Children appear to respond well to oral steroids.
