Abstract
We have observed the anesthesia at certain regions of the skin of leprous patients and the relation between anesthesia and disturbance of sweating at the same regions.
1) Twenty leprous patients were chosen and their tuberculoid macula of skin and the anesthesia were observed. It was noticed that the extent of tactile agnosia was generally wider than that of analgesia.
2) Thirteen cases were chosen and their lepromatous infiltrations, lepromatous nodule and clinical pictures of the skin anesthesia were observed. In some of them, the extent of analgesia was wider than that of tactile agnosia, and in the others it was in reverse order.
3) Thirtyfive cases of various types of leprosy were chosen and their skin without primary lepromatous change but with anesthesia were observed. It was noticed that region of analgesia was wider than that of tactile agnosia regardless of type, lepromatous or tuberculoid.
4) It was noticed that extent of paralysis of temperature sensation was widest of the four. Generally, extent of paralysis of warm sensation was wider than that of cold sensation.
5) It was considered that extent of sweatless area may not become wider than that of paralysis of skin sensitivity, according to the relation between the figure of anesthesia and the disturbance of sweating at tuberculoid macula and leucoderma leproua.
6) As for the relation between anesthesia and disturbance of sweating of lepromatous infiltration or lepromatous nodule, the region of sweatless part was smaller than that of analgesia, and there were two types, wider and smaller than the part of tactile agnosia.
7) As for the relation between anesthesia and disturbance of sweating at the part where skin sensitiveness had been paralysed without revealing primary lepromatous changes on the skin, many instances showed that the region of sweatless part was smaller than that of the anesthesia, but sometimes there was reverse condition.
