Preface

Companion to Peripheral Neuropathy is an extension of Peripheral Neuropathy, first to fourth editions, originally published by W.B. Saunders and then by Elsevier, Inc. Peripheral Neuropathy met the need for a comprehensive review of peripheral nerve neurobiology, pathology, and clinical disorders. P.K. Thomas, a co-editor of Peripheral Neuropathy, developed an incapacitating stroke during the preparation of the fourth edition and therefore could not participate in Companion to Peripheral Neuropathy. Thomas was an internationally renowned expert on peripheral nerve. He had a breadth of information and skill in writing and editing that we miss.

There were three developments that led to production of Companion to Peripheral Neuropathy. The first was introduction of magnetic resonance imaging (MRI)targeted fascicular nerve biopsy pioneered especially by three of the editors of this book (PJBD, KA, and RJS). The approach allows accurate anatomic localization and MRI characterization of focal nerve lesions identified by clinical and neurophysiologic studies. In appropriately chosen cases this further localization and characterization leads to surgical exposure, fascicular nerve biopsy, and pathologic identification of the pathologic process. As we demonstrate in this book, this frequently allows diagnosis not otherwise possible. However, as Jack Griffin said in discussing MRI-targeted fascicular nerve biopsy in a plenary session of the AAN, Dont do this at home. We infer that he saw the importance of the newly introduced approaches but warned against its misuse, recognizing that considerable harm could be done.
