The series, Current Management of Pain, is intended by the series editor and the publishers to provide up-to-date information on advances in the clinical management of acute and chronic pain and related research as quickly as possible. Both the series editor and the publishers felt that, although comprehensive texts are now available, they do not always cover the rapid advances in this field. Another format was needed to publish advances in basic sciences and clinical modalities and to bring them rapidly to the practitioners in the community. A questionnaire was sent to selected clinicians and, based on their responses, topics were chosen by the series editor. Editors of each volume were chosen for their expertise in the field and their ability to encourage other active pain specialists to contribute their knowledge.
