|Abstract:||The authors have used computerized digital thermometry for the instrumental diagnosis of Raynaud's phenomenon; such a technique enables them to evaluate the temperature of the ten fingers of the hands separately in baseline conditions, during and after the "cold test." In baseline conditions the mean digital skin temperature was 31.2 degrees C (SD 1.67) in control subjects and 26.8 degrees C (SD 2.84) in patients suffering from Raynaud's phenomenon (p less than 0.001). During the cold test the mean skin temperature decreased to 12.7 degrees C (SD 1.94) in control subjects and to 13.0 degrees C (SD 1.67) in patients (p = n.s.). The mean final skin temperature, at the end of the recovery period after the cold test, was 31.1 degrees C (SD 1.76) in controls and 21.9 degrees C (SD 2.78) in patients (p less than 0.001). The sensitivity of the computerized digital thermometry was high (63.6% and 92.7% for basal and final temperature, respectively), while the specificity was 100% for both values. In conclusion, computerized digital thermometry is a useful technique for the diagnosing and quantifying the extent of Raynaud's phenomenon.|
