Stroke:头痛早期,脑CT排除蛛网膜下腔出血敏感性较高

2016-07-25 phylis 译 MedSci原创

背景:新的证据表明早期脑部电脑断层扫描(CT)高灵敏度带来的问题,即CT诊断阴性后,必须进行腰椎穿刺诊断自发性蛛网膜下腔出血的(SAH)。研究者旨在确定头痛开始6小时内脑CT排除SAH的敏感性。方法:对Ovid MEDLINE, Ovid EMBASE, Web of Science和Scopus进行全面的文献检索,研究者进行了一项荟萃分析。纳入自发性蛛网膜下腔出血史的患者,在症状开始6小时内使用

背景:新的证据表明早期脑部电脑断层扫描(CT)高灵敏度带来的问题,即CT诊断阴性后,必须进行腰椎穿刺诊断自发性蛛网膜下腔出血的(SAH)。研究者旨在确定头痛开始6小时内脑CT排除SAH的敏感性。

方法:对Ovid MEDLINE, Ovid EMBASE, Web of Science和Scopus进行全面的文献检索,研究者进行了一项荟萃分析。纳入自发性蛛网膜下腔出血史的患者,在症状开始6小时内使用新一代的多排螺旋CT扫描的原始研究。研究以系统综述和荟萃分析作为优先报告项目(PRISMA)。

结果:总共对882个论文进行了审查,5篇论文符合纳入标准,包括8907例患者。6小时内脑CT未显示蛛网膜下腔出血(发生率1.46/1000)。CT的总敏感性为0.987(95%CI,0.971-0.994),特异性为0.999(95%CI,0.993-1.0)。阴性CT总似然比(likelihood Ratio, LR)为0.010(95%CI,0.003-0.034)。

结论:出现剧烈头痛和神经系统检查正常的患者,头痛6小时内脑CT排除动脉瘤性蛛网膜下腔出血是极其敏感的。

背景:非均匀性气道收缩和闭合是哮喘的特征。然而,到目前为止没有研究通过直接测量平行气道而获得图像数据,也就是说这一特征从来未被量化过,而且这些过程的解剖基础也仍不清楚。方法:7例正常受试者和9例哮喘受试者在予乙酰胆碱扩张气道的前后接受高分辨率的CT检查。分别测量28和24平行姐妹气道对(来自同一气道的分支,直径范围在1mm-8.7mm)的整个管腔的平均面积。非均匀性气道收缩被定义为是平行姐妹气道之
