Review Meta Analysis
Reliable estimation of the proportion of minor stroke due to intracerebral haemorrhage.
A previous hospital clinic-based study estimated that 3.5% of minor strokes are due to primary intracerebral haemorrhage, but the confidence intervals were wide. Moreover this figure may be an underestimate in older patients, who are less likely to be referred to secondary care, and who may have higher rates of intracerebral haemorrhage. Further studies are required to validate and increase the precision of this estimate and to determine any association with age, in order to plan appropriate services for minor stroke. ⋯ We have shown that the proportion of minor stroke due to intracerebral haemorrhage was very similar in a population-based cohort and a hospital clinic-based cohort using different imaging strategies, and that the frequency is independent of age. A frequency of between 4.5 and 5.0% appears to be a reliable estimate at all ages.

Randomized Controlled Trial Multicenter Study
A double-blind, placebo-controlled, randomized, multicenter study to investigate CHInese Medicine Neuroaid Efficacy on Stroke recovery (CHIMES Study).
Rationale Traditional Chinese Medications(TCM) have been reported to have beneficial effects in stroke patients, but were not rigorously evaluated by GCP standards. Aim This study tests the hypothesis that Neuroaid, a TCM widely used in China post-stroke, is superior to placebo in reducing neurological deficit and improving functional outcome in patients with acute cerebral infarction of an intermediate severity. Design This is a multicenter, randomised, double-blind, placebo-controlled study of Neuroaid in ischemic stroke patients with National Institute of Health Stroke Scale(NIHSS) 6-14 treated within 48 h of stroke onset. Neuroaid or placebo is taken (4 capsules) 3 times daily for 3 months. Treatments are assigned using block randomization, stratified for centers, via a central web-randomization system. With a power of 90% and two-sided test of 5% type I error, a sample size is 874. Allowing for a drop-out rate of up to 20%, 1100 individuals should be enrolled in this study. Study Outcomes The primary efficacy endpoint is the modified Rankin Scale(mRS) grades at 3 months. Secondary efficacy endpoints are the NIHSS score at 3 months; difference of NIHSS scores between baseline and 10 days, and between baseline and 3 months; difference of NIHSS sub-scores between baseline and 10 days, and between baseline and 3 months; mRS at 10 days, 1 month, and 3 months; Barthel index at 3 months; Mini Mental State Examination at 10 days and 3 months. Safety outcomes include complete blood count, renal and liver panels, and electrocardiogram. ⋯ ClinicalTrials.gov identifier: NCT00554723.

Randomized Controlled Trial Multicenter Study
Minimally invasive craniopuncture therapy vs. conservative treatment for spontaneous intracerebral hemorrhage: results from a randomized clinical trial in China.
To evaluate the effects of minimally invasive craniopuncture therapy compared with conservative treatment in treating intracerebral hemorrhage (25-40 ml) in the basal ganglion. ⋯ This minimally invasive craniopuncture technique can improve the independent survival of patients with small basal ganglion hemorrhage. It is a safe and practical technique in treating cerebral hemorrhage.
