Telethermographic study of skin circulation in smokers

Skin vascular diseases are accompanied by changes of the temperature of the skin. However, modifications of thermal gradients are often < 0,1°C. The thermostimulation method let us to overcome the accuracy of the current devices. Infact, performing by contact a cold/hot stimulus under controlled conditions, it is possible to evaluate thermal gradients of a hot/cold spot, by timering its thermal recovery. On these bases, we have performed a study of early effects of cigarette smoking. Infact, among the acute effects of cigarette smoking there is a capillary vasoconstriction. However this effect is not similar in all the subjects.
