Review Meta AnalysisSelective serotonin reuptake inhibitors (SSRIs) for stroke recovery.
Stroke is the major cause of adult disability. Selective serotonin reuptake inhibitors (SSRIs) have been used for many years to manage depression. Recently, small trials have demonstrated that SSRIs might improve recovery after stroke, even in people who are not depressed. Systematic reviews and meta-analyses are the least biased way to bring together data from several trials. Given the promising effect of SSRIs on stroke recovery seen in small trials, a systematic review and meta-analysis is needed. ⋯ SSRIs appeared to improve dependence, disability, neurological impairment, anxiety and depression after stroke, but there was heterogeneity between trials and methodological limitations in a substantial proportion of the trials. Large, well-designed trials are now needed to determine whether SSRIs should be given routinely to patients with stroke.

Up to one percent of people in industrialised countries will suffer from a leg ulcer at some time. The majority of these leg ulcers are due to problems in the veins, resulting in an accumulation of blood in the legs. Leg ulcers arising from venous problems are called venous (or varicose or stasis) ulcers. The main treatment is the application of a firm compression garment (bandage or stocking) in order to aid venous return. There is a large number of compression garments available and it was unclear whether they are effective in treating venous ulcers and, if so, which method of compression is the most effective. ⋯ Compression increases ulcer healing rates compared with no compression. Multi-component systems are more effective than single-component systems. Multi-component systems containing an elastic bandage appear to be more effective than those composed mainly of inelastic constituents. Two-component bandage systems appear to perform as well as the 4LB. Patients receiving the 4LB heal faster than those allocated the SSB. More patients heal on high-compression stocking systems than with the SSB. Further data are required before the difference between high-compression stockings and the 4LB can be established.

Review Meta AnalysisRecombinant human insulin-like growth factor I (rhIGF-I) for the treatment of amyotrophic lateral sclerosis/motor neuron disease.
Recombinant human insulin-like growth factor I (rhIGF-I) is a possible disease modifying therapy for amyotrophic lateral sclerosis (ALS, which is also known as motor neuron disease (MND)). ⋯ Meta-analysis revealed a significant difference in favour of rhIGF-I treatment; however, the quality of the evidence from the two included trials was low. A third study showed no difference between treatment and placebo. There is no evidence for increase in survival with IGF1. All three included trials were at high risk of bias.

Review Meta AnalysisClomiphene citrate in combination with gonadotropins for controlled ovarian stimulation in women undergoing in vitro fertilization.
Gonadotropins are the most commonly used medication for controlled ovarian stimulation in in vitro fertilization (IVF). However, they are expensive, invasive and are associated with risk of ovarian hyperstimulation syndrome (OHSS). With recent calls for patient friendly IVF, there has been an interest in the use of clomiphene citrate with or without gonadotropins to reduce the burden of injections. However, it is not known whether regimens using clomiphene are at least as effective as gonadotropins alone. ⋯ There was no evidence to indicate that clomiphene with gonadotropins (with or without GnRH antagonist) differed significantly from gonadotropins in GnRH agonist protocols for women undergoing IVF treatment, in terms of live births or pregnancy rates. Meanwhile, use of clomiphene led to a reduction in the incidence of OHSS. However, these results were based on data from a small number of underpowered randomised trials with few participants. Hence there was insufficient evidence to recommend use of clomiphene citrate in routine IVF practice. Larger trials with adequate power are required.

ReviewKetamine for management of acute exacerbations of asthma in children.
Asthma is the most common chronic disease in children, and children with asthma frequently visit the paediatric emergency departments with acute exacerbations. Some of these children fail to respond to standard therapy (aerosol beta(2)-agonist with or without aerosol anticholinergic and oral or parenteral corticosteroids) for acute asthma leading to prolonged emergency department stay, hospitalisation, morbidity (e.g. barotrauma, intubation) and death, albeit rarely. Ketamine may relieve bronchospasm and is a potentially promising therapy for children with acute asthma who fail to respond to standard treatment. ⋯ The single study on non-intubated children with severe acute asthma did not show significant benefit and does not support the case studies and observational reports showing benefits of ketamine in both non-ventilated and ventilated children. There were no significant side effects of ketamine. We could not find any trials on ventilated children. To prove that ketamine is an effective treatment for acute asthma in children, there is need for sufficiently powered randomised trials of high methodological quality with objective outcome measures of clinical importance. Future trials should also explore different doses of ketamine and its role in children needing ventilation because of severe acute asthma.
