This up-to-date and comprehensive set of two CD-ROM discs provides a superb collection of authoritative documents on the subject of psoriasis. Psoriasis is a skin disease that causes itchy or sore patches of thick, red skin with silvery scales. You usually get them on your elbows, knees, scalp, back, face, palms and feet, but they can show up on other parts of your body. A problem with your immune system causes psoriasis. In a process called cell turnover, skin cells that grow deep in your skin rise to the surface. Normally, this takes a month. In psoriasis, it happens in just days because your cells rise too fast. For patients, practical information is provided in clearly written patient education documents. For medical professionals, doctor reference tools and texts have detailed technical information and clinical background material. There is no other reference that is as fast, convenient, and portable - everything you need to know, from the federal sources you trust.
