BACKGROUND
Clinicians need an accurate diagnostic test for hand-arm vibration syndrome (HAVS).
AIMS
To validate a simple thermometric method to diagnose HAVS-related Raynaud's phenomenon.
METHODS
Fifteen workers with photographically confirmed HAVS-related Raynaud's phenomenon were compared to controls without Raynaud's phenomenon and an occupational history of hand-arm vibration exposure. Digit temperatures were measured using an infrared thermometer before and after immersion in 5 degrees C water for 1 min.
RESULTS
The HAVS patients differed significantly from the controls in terms of baseline temperature, rewarming time and rate. The fingertip-base temperature gradient was more commonly positive among the controls.
CONCLUSIONS
The test method evaluated in this study is simple, cheap and accurate. If the pre-test probability is at least 35%, the best test variable to confirm the diagnosis of HAVS-related Raynaud's phenomenon is the time to rewarm to baseline of the first three fingertips providing the interval is > or =8-9 min.
背景
临床医生需要一种准确的诊断测试来诊断手部振动综合征（HAVS）。
目的
验证一种简单的测温方法来诊断与 HAVS 相关的雷诺现象。
方法
将 15 名经照片证实患有 HAVS 相关雷诺现象的工人与无雷诺现象和手部手臂振动暴露职业史的对照组进行比较。使用红外线温度计在浸入 5 摄氏度水中 1 分钟前后测量指尖温度。
结果
HAVS 患者与对照组在基础体温、复温时间和速率方面存在显著差异。对照组的指尖-基底温度梯度更常见为阳性。
结论
本研究评估的测试方法简单、廉价且准确。如果预测试概率至少为 35%，则确认 HAVS 相关雷诺现象诊断的最佳测试变量是前三个指尖恢复到基线的时间，前提是间隔时间≥8-9 分钟。
