Psoriasis

Psoriasis is a chronic, autoimmune condition affecting the skin. Approximately 1% of the population is affected by the disease, and there is a genetic component. Psoriasis is not contagious. Approximately 30% of patients with psoriasis may have joint disease called psoriatic arthritis, which necessitates effective treatment to avoid permanent joint damage. There are several forms of psoriasis. The most common, psoriasis vulgaris, appears as red patches with overlying silver-white flakes that are found on the elbows, knees, body, and scalp. Other variants can occur in body folds or on the hands and feet, or even following a streptococcal bacterial infection. Many times, the fingernails or toenails are affected by psoriasis. Treatment for psoriasis depends on the location and severity of the condition. Various topical prescriptions including steroids, calcineurin inhibitors, or tar therapy is the mainstay of treatment. Light therapy, oral medications, and injectable biologic therapy are all treatment options in more significant cases of psoriasis.
