This title offers a plain-speaking introduction to psoriasis: the nature of the disease and treatments. Psoriasis is a chronic inflammatory, but non-contagious skin disease that affects as many as one in 50 adults - making it arguably the world's most common skin disorder. It can appear at any age and can affect relationships, the ability to work, and the ability to enjoy leisure activity. In this second, revised and fully updated edition Dr. Langley presents a detailed look at all this too common problem. In clear and accessible language, he offers insight into the nature of the disease, its potential treatments, and their relative benefits and risks - information that will enable patients to achieve a significantly better quality of life.
