Correlation between self-reported recovery and central sensitization in whiplash patients

Central sensitization has been associated with chronic pain in whiplash patients.Methods:Consecutive whiplash patients were assessed at 3 months post-whiplash injury with the brachial plexus provocation test(BPPT)as a sign of central sensitization.Self-reported recovery was assessed by the response to the question ‘Do you feel you have recovered fully from your accident injuries?'Results:Sixty-nine subjects(32 males,37 females,age 37.5±13.0 years(mean±SD),range 18-71)were included.Of these,34 reported a lack of recovery,and 35 reported recovery at 3 months post-injury.The mean BPPT elbow extension(from 180°)was 41.5±23.0°,and the mean VAS score for the BPPT was 2.2 ± 1.2(out of 10).Those who reported recovery had a mean BPPT elbow extension angle of 25.1±15.8 while those who did not report recovery had a mean BPPT angle of 58.4 ± 15.9(P＜0.05).The visual analogue scale(VAS)score for recovered subjects was 1.8 ± 1.1 and 2.7 ± 1.1(P＜0.05)for non-recovered.There was a moderate correlation between self-reported recovery and BPPT elbow extension angle(-0.44)and a lower correlation between self-reported recovery and VAS score(-0.30).Conclusion:Self-reported recovery correlates well with a lower likelihood of signs of central sensitization.Copyright(c)2012,Shanghai University of Sport.Production and hosting by Elsevier B.V.All rights reserved.

过敏原免疫治疗对呼吸道过敏性疾病致敏原谱的影响:3年回顾性研究

目的探讨接受过敏原免疫治疗(AIT)的呼吸道过敏性疾病患者出现新增过敏原的情况及危险因素。方法回顾性收集2011至2016年在本科室接受AIT的过敏性鼻炎和/或哮喘患者的临床资料。结果本研究共纳入1640例患者(男性649例),平均年龄17.7岁。免疫治疗后,413例(25.2%)患者出现新增过敏原。单一致敏患者与多重致敏相比出现新增过敏原的概率降低(OR=0.432,95%CI:0.342~0.545)。134例患者纳入生存曲线分析,结果显示在AIT开始后0.5、1.5、2.5和3年时,出现新增过敏原的患者比例分别为14.2%、17.2%、18.7%和26.1%。多重致敏患者相比单一致敏患者出现新增过敏原的速率更快(P=0.024)。结论过敏性鼻炎和/或哮喘患者在接受AIT后,仍有少数患者出现新增过敏原。单一致敏患者与多重致敏患者相比出现新增过敏原概率降低。新增过敏原多出现在AIT早期,随着时间延长,出现新增过敏原的速率呈现逐渐降低趋势。
