BLISTER DISEASE, (Pemphigus).—This is an acute or chronic skin disease in which there are blisters of various sizes and shapes, and these usually occur in crops.
Symptoms.—The disease may attack any part of the body. The blisters range from the size of a pea to a large egg. They contain at first a clear fluid, which soon becomes cloudy and looks more or less like pus. They last several days and then dry up. They do not rupture of themselves very often. It is not catching.
Causes.—These are obscure and not understood. A low state of the system is usually found.
PHYSICIANS' TREATMENT for Blister Disease.—General treatment should be given. Arsenic is the best remedy and can be given in the form of Fowler's solution, five drops after meals at the beginning far an adult. This should be increased until some poisonous symptoms, such as bloating in the face is produced.
Elixir Quinine, Iron and Strychnine is good as a tonic, one teaspoonful after meals. Regulate the diet, give nourishing and easily digested food.
Local Treatment.—Puncture the blisters. Then put on a mild ointment like vaselin; bran and starch baths can be given in some cases. The length of the time of the disease is uncertain.
THE ITCH DISEASE. (Psoriasis) (not Common Itch). Definition.—This is a chronic inflammatory disease of the skin, in which there appear upon the skin thick, adherent, overlapping, scales of a shiny, whitish color, and these are situated upon a reddish, slightly raised and sharply outlined (defined) base.
Symptoms.—They begin as small reddish spots, sharply defined against the healthy skin. They may be elevated slightly and soon became covered with whitish pearl colored scales. If the scales are picked off, there is left a smooth red surface, and from this, small drops of blood ooze out. No watery or pus-like discharge escapes at any period of this disease. These spots extend at the circumference (periphery), reaching the size of the drops, or of the coins, or they may run together and form ring-shaped, or crooked wavy lines of patches, with a center that is healing up. A few scattered spots may be present, or large areas may be involved. In rare cases the whole skin is affected. These spots or patches may occur an any part of the body, but involve the extending part of the limbs, especially the elbows and knees. There may be slight itching present at times.
