About Psoriasis

Psoriasis is a chronic (long-lasting) skin disease of scaling and inflammation that affects greater than 3 percent of the U.S. population, or more than 5 million adults. Although the disease occurs in all age groups, it primarily affects adults. It appears about equally in males and females.

Psoriasis occurs when skin cells quickly rise from their origin below the surface of the skin and pile up on the surface before they have a chance to mature. Usually this movement (also called turnover) takes about a month, but in psoriasis it may occur in only a few days... NIH - National Institute of Arthritis and Musculoskeletal and Skin Diseases

Treatments for guttate psoriasis

Psoriasis is a skin disease that causes scaly pink patches. Guttate psoriasis is a particular form of the disease that usually affects children and young adults. It can happen on its own, or as a complication of ordinary (chronic plaque) psoriasis. Often, it follows a bacterial throat infection or tonsillitis. Antibiotics and tonsillectomy as treatments for guttate psoriasis are covered by another review. This review could find no evidence, from trials, about the effects of any other commonly used treatments for guttate psoriasis.

Antibiotics or tonsillectomy for people with psoriasis.

Psoriasis, a disease which produces scaly pink patches on the skin, often gets worse after a bacterial throat infection or tonsillitis. When someone with psoriasis has a throat infection, antibiotics are sometimes used in an attempt to prevent this from happening. For people with psoriasis and repeated throat infections tonsillectomy is sometimes recommended. The review found no evidence from trials that either antibiotics or tonsillectomy are helpful for people with psoriasis.

Treatments for nail psoriasis

Psoriasis is a common chronic skin disease with a prevalence in 2% to 3% of the population, according to European studies. Involvement of the nails occurs in about 50%. Nail psoriasis is difficult to treat, but may respond to some treatments. We aimed to review the efficacy and safety of the treatments used for nail psoriasis.
