PSORIASIS

As far as we know, psoriasis is not an allergic condition. In fact, its cause has not been found. We do know that it is not due to an infection, and it is not catching. It does not appear to be related to diet. It may run in families. It seems to bear some relationship to lack of sunlight, as it is less common in the tropics, rarely appears on the exposed parts of the body such as the face, and usually gets worse in winter. Emotional factors may also play a part in this disease.

In psoriasis, rounded or scalloped red patches, with sharp borders, appear on the skin. They are covered by layers of shiny, silvery, dry scales resembling the scales of mica. They appear most frequently on the elbows, knees, lower back, and scalp. The hair is apt to fall out in the affected scalp areas, but, fortunately, it usually grows in again. The soles of the feet, folds of the body—in fact, any place—can be covered with these patches, and often they must be bandaged to prevent the clothing from sticking to them.

Psoriasis is resistant to treatment; it may be chronic or acute; even if it clears up, it is almost bound to recur. There is no known cure. But a doctor experienced in treating this condition can do a great deal for the itching and disfigurement.
