Pain: Basics and relevance in dermatology

P>Scientific progress in pathophysiology and differentiation of pain, functional diagnostic of pain and emerging treatments highlight this subject. Basics of development of pain, as well as differentiation of nociceptive and neuropathic pain are depicted; the latter is illustrated with the example of postherpetic neuralgia. Complex regional pain syndromes are described as a third pain complex. Principles of differentiated pain management are given. Substance groups from the WHO scheme including antipyretic analgesics, non-steroidal antiinflammatory drugs (NSAIDs) and opioids are discussed. Recommendations of the Drug Commission of the German Medical Association concerning NSAIDs and of the International Association for the Study of Pain (IASP) concerning new treatment options for cancer pain are cited. Overviews amongst others from the Cochrane library for local anesthetics, opioids and for the treatment of postherpetic neuralgia are included. Tables are provided to simplify use in daily practice. The goal of this overview is a conceptual development of pain diagnosis and therapy in dermatology.
