MEASUREMENTS OF CAPILLARY RESISTANCE IN A TOPIC-DERMATITIS

For over 100 years many different methods have been used to determine capillary resistance as a measure of small vessel fragility. There is still no firm agreement as to the most suitable method; the procedure is not standardized and an objective system for measurement is lacking . We have developed a computerized system that makes it possible to co unt petechiae and determine their area without the results varying wit h different examiners. Although we tried to keep the conditions for ou r examinations constant, we found a wide individual spread. In spite o f this, the capillary resistance of atopic subjects was significantly lower than that of healthy persons.
