978-3-540-78814-0 (ISBN)
Based on the understanding of the molecular basis of skin diseases, this truly international book supports the reader to understand the mode of action of new and established therapies. Thus, by explaining the molecular pathology with its applications for therapy, it provides the reader with an up-to-date knowledge of the therapy of skin disease and helps to understand ongoing and new developments in the field. Written and edited by international and renowned dermatology experts from Europe, America and Asia, it also includes regional concepts of therapies.
The reader-friendly structure allows the reader to pick up the information quickly; for example, each chapter highlights practical hints for indications and applications. This lavishly illustrated book will support the reader to choose the most appropriate therapy for the patient and to reach a better treatment outcome. It will be an indispensable resource for dermatologists in university departments as well as in clinical practice.
