Psoriasis
Psoriasis is a skin disorder in which the skin becomes inflamed, producing patches of red thickened areas covered with silvery scales. These patches occur most often on the scalp, face, elbows, palms of the hands, knees, lower back and the soles of the feet, and are usually found on both sides of the body. Psoriasis may also affect the fingernails and soft tissues of the mouth and genitalia.
The term psoriasis comes from the Greek word meaning "itch". The cause of psoriasis is unknown but is believed to be a disorder of the immune system. Some cases may be inherited.
There are several types of psoriasis, each distinguished by severity, location, duration and shape of the scales. The most common form is known as Plaque Psoriasis, characterized by reddened lesions covered by silvery scales. The top scales flake off and when the underneath scales are removed, the tender exposed skin bleeds. These red areas then grow in to larger areas. Other forms include the following: Guttate Psoriasis which is triggered by viral infections and found in children and young adults and is characterized by drop-like scaly spots; Postular Psoriasis is triggered by medication, sunlight, infection and/or emotional stress and is characterized by blisters appearing on the skin. Erytrhodermic Psoriasis is characterized by widespread reddening and scaling of the skin accompanied by pain and itching, and may be precipitated by severe sunburn or use of oral steroids. Inversion Psoriasis is characterized by large, dry, smooth red plaques usually found in the folds of the skin. Eighty (80%) percent of people with psoriasis develop symptoms of arthritis.
Treatment is based on the severity of the condition. The 1-2-3 approach is the most common form of treatment. Step 1 is a topical application of medication applied to the skin. Step 2 is phototherapy or treatment using light. Step 3 is a systemic treatment utilizing oral medications. The goal of treatment is to decrease inflammation and control the shedding of the skin.
