Digital arterial responsiveness to cold in healthy men, vibration white finger and primary Raynaud's phenomenon.

Vibration-induced white finger and cold response of digital arterial vessels in occupational groups with various patterns of exposure to hand-transmitted vibration

“…The findings of this study tend to confirm the conclusions of previous studies performed on smaller samples of vibrationexposed workers (3)(4)(5)(6)(7)(8), namely, the measurement of FSBP during local cooling can be considered an accurate laboratory test to differentiate between subjects with and without white fingers. This finding is also consistent with the results reported by other authors (16), who found that the digital pressure response to cooling was useful for the differential diagnosis of patients affected with nonoccupational vasospastic syndromes, such as cold sensitivity, primary Raynaud's phenomenon, and secondary Raynaud's phenomenon in scle- could not, however, differentiate between persons with dif-* P < 0.001, one-way analysis of covariance (covariates: age, smoking and drinking habits); * * P < 0.001, chi-square test for trend.…”

“…The accuracy of FSBP measurement during cooling in the detection of white fingers has been assessed mainly in clinical or laboratory work using either small groups of vibration-exposed workers or patients diagnosed consecutively with mild to severe white fingers (3)(4)(5)(6)(7)(8). There is a shortage of epidemiologic data on the usefulness of FSBP testing methods in assessments of white fingers in worker groups with different patterns of exposure to hand-transmitted vibration.…”

Simultaneous Observation of Zero‐Value of FSBP% and Raynaud's Phenomenon during Cold Provocation in Vibration Syndrome

“…Therefore, it is considered that zero value of FSBP% confirms Raynaud's phenomenon in a laboratory. FSBP% is also known to show higher sensitivity and specificity for diagnosis of vibrationinduced white finger, than a cold water immersion test [4][5][6][7] . In this case the FSBP% value of the little finger was 0%.…”

Effect of prior exposure to hand-transmitted vibration on cold response of digital arteries

“…The measurement of finger systolic blood pressure (FSBP) during cold provocation is considered a useful laboratory test for quantifying the degree of cold-induced digital vasospasm in vibrationexposed workers [1,3,12,20].…”
