Brain Edema Xi

The Symposium on Brain Edema has been organized by the Osterreichische Arbeitsgemeinschaft fur Neuropathologie and by the Problem Commission for Neuropathology of the World Federa tion of Neurology. We would like to express our thanks to Dr. L. van Bogaert, president of the W.F.N., for his great interest in the design of this conference and for his energetic support. One of the aims ofthe Problem Commission for Neuropathology has been to contribute to the advances in various problems which are becoming ripe for elucidation by experts in different fields. The idea of the Symposium on Brain Edema has as its background a compelling necessity to elucidate this subject which is clinically so important and neuropathologic ally so poorly understood. It was hoped that this could be achieved by a multidisciplinary approach involving a variety of aspects to be discussed and correlated. Brain edema, being an abnormal cerebral condition, belongs basically to the sphere of neuropathology, but to be successful in our endeavors we had to apply neuropathology in its most modern and widest terms. By this we understand that such neuropathology includes the study of all abnormal phenomena in the nervous tissue related to the structural alterations, and by "structural" we mean not only tissual or cellular ones but also changes on ultrastructural and molecular levels. Thus we needed close and integrated coopera tion of experts in fields such as neurohistology, histochemistry, electron microscopy, neurochemistry, and neurophysiology.

Brain edema is found in a wide variety of clinical disorders including stroke, intracerebral haemorrhage, subarachnoid haemorrhage, head injury, brain tumors and hydrocephalus. This volume brings together clinical and basic scientists from all over the world. Their expertise in the understanding of brain edema and shifts in brain water compartments has led to a further significant step in our understanding of those diseases characterized by brain edema. This book has also drawn on the expertise of the International Advisory Board of the Brain Edema Society, who have carefully summarized each section, thus providing an easy-to-read summary of the latest advances in each subject. The book is therefore much more than a collection of papers: it represents a critical appraisal and puts each paper into modern scientific context. The greatest advances have come from the rapid development of modern imaging techniques, especially with magnetic resonance imaging (MRI). Imaging can now produce "water maps” and "metabolic profiles” that bring brain metabolism and water content right into every clinic with access to MRI. This book provides the background knowledge to understand these pathophysiological changes.

This volume contains 93 papers from internationally recognized experts in the field of brain edema and brain injury. The papers include human and animal studies on edema following stroke, cerebral hemorrhage, traumatic brain injury, spinal cord injury and hydrocephalus. Papers also address fluid dynamics in the brain (including the role of aquaporins).

In this book, leading world authorities on brain edema and neurological disorders/injuries and experts in preconditioning join forces to discuss the latest progress in basic sciences, translational research, and clinical management strategies relating to these conditions. The range of topics covered is wide, including microglia, energy metabolism, trace metals and ion channels, vascular biology, cellular treatment, hemorrhagic stroke, novel technological advances, anesthesia and medical gases, pediatric brain edema, neuroimaging, behavioral assessment, clinical trials, peripheral to central signaling pathways, preconditioning translation, and animal models for preconditioning and brain edema research. The book comprises presentations from Brain Edema 2014, the joint meeting of the 16th International Conference on Brain Edema and Cellular Injury and the 3rd Symposium on Preconditioning for Neurological Disorders, held in Los Angeles on September 27–30, 2014.

The first International Symposium on Brain Edema was organized by Dr. Klatzo and Dr. Seitelberger and held in Vienna in 1965. The second Symposium was held in Mainz in 1972 and organized by Dr. H.J. Reulen and Dr. K. Schiirmann, the third in Montreal in 1976 by Dr. H.M. Pap pius, the fourth in Berlin in 1979 by Dr. J. Cervos-Navarro, and the fifth in Groningen in 1982 by Dr. K.G. Go. This volume contains the papers presented at the 6th International Sym posium on Brain Edema, held in Tokyo, Japan, November 7-10, 1984. The invited lectures by Dr. I. Klatzo, Dr. A. Hirano, Dr. S.I. Rapoport, Dr. B.K. Siesj6, Dr. H.M. Pappi us, Dr. K.A. Hossmann, and Dr. D.M. Long are included as special chapters. On behalf of the organizing committee, I wish to express my deep ap preciation to all the participants for their contribution toward making this meeting so fruitful and significant. Moreover, the great success of this Sym posium depended on the high quality of the invited lectures and presen tations by experts in various fields, as well as on the free and enthusiastic discussion. I was deeply impressed with the papers presented by all the authors, who endeavored to elucidate their subjects. The editors have made only minor corrections and rearrangements, since prompt publi cation was considered to be important.

A workshop on Dynamic Aspects of Cerebral Edema was organized to pro vide an opport~nitY,for interdisciplinary and detailed consideration of this subject, so crucial in neurology and neurosurgery. The previ ous workshops were held in Vienna in 1965 and in Mainz in 1972. In the meantime, our ideas on mechanisms of resolution of cerebral edema had been changing drastically. Controversy had arisen regarding the role of biogenic amines in the development of edema. Active work in several centers had indicated the possibility of a reversible compo nent in edematous changes associated with ischemia, the control of which could be of therapeutic significance in the problem of stroke. It was felt that a thorough discussion, at this time, by those involv ed in these various studies should help to resolve the controversies, to crystallize the implications of the new findings, and to evaluate their application for patient care. In preparing the proceedings for publication we have edited the manu scripts and selected the discussions with an aim to highlight new find ings, to make this volume readable, and to eliminate duplication. We gratefully acknowledge financial support from the institutions and organizations previously listed. Many individuals contributed to the success of the workshop and the preparation of the proceedings for publication. Doctors J.B. Brierley, I. Klatzo, H.J. Reulen, and A.G.
