OBJECTIVETo discuss the effects of criteria in controlling the risk factors on secondary prevention of brain vessel disease.

METHODSAmong 631 cases who had been examined at our hospital on brain vessel disease for longer than 1 year, 123 cases were chosen as treatment group which received criterion therapy to control their risk factors while the rest cases were under antitheses group. The two groups were compared on the 1 year recrudesce rate thereafter.

RESULTSThe 1 year recrudesce rate of the treatment group showed better than the antitheses group (P = 0.005 < 0.05), as the benefit mostly from the control of risk factors, such as blood pressure (P = 0.005), blood sugar (P = 0.038). There was active effect of criterion therapy in controlling the risk factors.

CONCLUSIONThere was active effect of criterion therapy in controlling the risk factors as high blood pressure, high blood sugar and high blood fat etc. Healthy life style would help the recurrence of brain vessel disease, which should be highlighted in the secondary prevention of brain vessel disease.

OBJECTIVE: We aimed to evaluate the combined effects of a high body shape index (ABSI) and a high serum C-reactive protein (CRP) level on the incidence of ischemic stroke in a Mongolian population in China. METHODS: A prospective cohort study was conducted among 2,589 participants from June 2002 to July 2012 in Inner Mongolia, China. The participants were categorized into 4 groups according to their level of ABSI and CRP. Cox proportional hazards models were used to assess the hazard ratios (HRs) and 95% confidence intervals (CIs) for ischemic stroke among all groups. RESULTS: The multivariate adjusted HRs (95% CI) of ischemic stroke for high ABSI and high CRP level were 1.46 (0.89-2.39) and 1.63 (0.95-2.79), respectively. Compared with the low ABSI/low CRP level group, the multivariate adjusted HRs (95% CI) of ischemic stroke in the low ABSI/high CRP, high ABSI/low CRP, and high ABSI/high CRP groups were 1.04 (0.46-2.35), 1.06 (0.58-1.95) and 2.52 (1.27-5.00), respectively. The HR of ischemic stroke for the high ABSI/high CRP level group was the highest and most statistically significant. CONCLUSION We found that participants with simultaneously high ABSI and high CRP levels had the highest risk of ischemic stroke in the Mongolian population. Our findings suggest that the combination of high ABSI and high CRP levels may increase the risk of ischemic stroke.

INTRODUCTIONWhile paediatric strokes are fairly uncommon, they are often associated with significant long-term disability. Diagnosis is often delayed because of the need to exclude conditions that mimic stroke. Understanding the outcomes related to stroke in children is important in the development of secondary prevention strategies. The aim of this study was to evaluate the epidemiology of childhood stroke in a tertiary paediatric unit in Singapore and to assess factors influencing outcome in these children.

MATERIALS AND METHODSA retrospective case-note review of all childhood strokes presenting to the Children's Medical Institute (CMI) at the National University Hospital (NUH), Singapore between October 1999 and May 2006. Data collected include demographic factors, clinical presentation, diagnosis, subsequent management and follow-up using specific outcome measures.

RESULTSTwenty-six children with a median age of 8.0 years at presentation were identified, comprising 15 ischaemic strokes (57.7%), 10 haemorrhagic strokes (38.5%) and 1 patient with both ischaemic and haemorrhagic lesions. The most common symptoms at presentation were seizures (15/26, 57.7%), lethargy (11/26, 42.3%), hemiparesis (10/26, 38.5%) and altered levels of consciousness (10/26, 38.5%). Vascular abnormalities accounted for 50% of strokes in our study population. The average length of follow-up was 33.2 months (range, 1 to 120) with only 11 children (11/26, 42.3%) achieving full recovery. Significant prognostic factors include altered consciousness and seizures at presentation, lesions in both cortical and subcortical locations, systemic disease aetiology, neurological deficits at discharge and seizures at the time of discharge.

CONCLUSIONLong-term neurological, neuropsychological and functional impairment are common in survivors of paediatric strokes. Certain clinical features and lesion characteristics are useful indicators of prognosis in these children.

OBJECTIVETo study the incidence and the risk factors of dysphagia after ischemic stroke in Chengdu City, China.

METHODSReview was made with unified questionnaire on dysphagia after ischemic stroke in 563 patients from four hospitals, from January to December 2005. Over 20 risk factors related to dysphagia after ischemic stroke were analyzed by logistic regression.

RESULTSThe total incidence of dysphagia after ischemic stroke was 13.3% in Chengdu. Data from logistic regression analysis indicated that gender, morbidity frequency, basal nuclei, periventricular lesion, hypertension, pneumonia, hyperlipemia, cervical spondylosisi, internal carotid artherosclerosis were closely related to dysphagia after ischemic stroke,with OR values as 0.416, 0.489, 0.327, 0.454, 2.187, 2.146, 0.352, 0.242 and 0.273 respectively.

CONCLUSIONThe total incidence was lower than literature published from home and abroad. Gender, morbidity frequency, basal nuclei, periventricular lesion, hypertension, pneumonia, hyperlipemia, cervical spondylosisi and internal carotid artherosclerosis seemed to be risk factors to dysphagia after ischemic stroke.

PURPOSE: Despite undergoing successful catheter ablation of typical atrial flutter (AFL), patients remain at increased risk for ischemic stroke. However, data on risk prediction tools for the development of stroke after AFL ablation are lacking. This study investigates whether CHA₂DS₂-VASc score is useful for predicting ischemic stroke after successful ablation of typical AFL. MATERIALS AND METHODS: A total of 293 patients (236 men, mean age 56.1±13.5 years) who underwent successful radiofrequency catheter ablation for typical AFL were included in this study. The clinical end point was occurrence of ischemic stroke during follow-up after AFL ablation. RESULTS: During the follow-up period (60.8±45.9 months), ischemic stroke occurred in 18 (6%) patients at a median of 34 months (interquartile range, 13–65 months). CHA₂DS₂-VASc score [hazard ratio 2.104; 95% confidence interval (CI), 1.624–2.726; p < 0.001] was an independent predictor for the occurrence of stroke after AFL ablation. The area under the receiver operating characteristic curve for CHA₂DS₂-VASc score was 0.798 (95% CI, 0.691–0.904). The CHA₂DS₂-VASc score could be used to stratify patients into two groups with different incidences of ischemic stroke (1.6% vs. 14.4%, p < 0.001) at a cutoff value of 2. CONCLUSION: CHA₂DS₂-VASc score is useful in a prediction model for the risk of stroke after catheter ablation of typical AFL.
