[Absence of the formation of wrinkles of the finger tips in leprosy].

Soaking of the hand of leprosy patients in water of 38 degrees--40 degrees C during half an hour does not lead to the formation of wrinkles, in contrast to healthy individuals. We tend to relate this lack of wrinkles to the damaged nerve ends which are often found in leprosy patients. The number of investigated individuals is small and repeated experiments are therefore required.
