Severe spondylolisthesis/spondyloptosis is still a controversial issue in spine surgery. This book takes an interdisciplinary approach and discusses the state of the art and defines therapeutic strategies. The contributing authors are well-known specialists in the field.

It was only in 1980 that the first recognisable magnetic resonance images of the human brain were published, by Moore and Holland from Nottingham University in England. There then followed a number of clinical trials of brain imaging, the most notable from the Hammersmith Hospital in London using a system designed by EMI, the original manufacturers of the first CT machines. A true revolution in medicine has ensued; in only a few years there are thousands of scanning units, and magnetic resonance imaging (MRI) has assumed a central importance in medical investigation. It is an extraordinary fact that within a few years of development, the esoteric physics of nuclear spin, angular momentum, and magnetic vector precession were harnessed to provide exquisite images of living anatomy; modem science has no greater tribute. That indisputable king of neurology and the oldest of recorded conditions, epilepsy, has not been untouched by the new technology; indeed, it is our view that the introduction of MRI of electroencephalography (EEG) in the late has been as important to epilepsy as was that 1930s. Now, for the first time, the structural and aetiological basis of the condition is susceptible to thorough investigation, and MRI can provide structural detail to parallel the functional detail of EEG. MRI has the same potential as had EEG over 50 years ago, to provide a new level of understanding of the basic mechanisms, the clinical features and the treatment of epilepsy.

Brain edema is a simple phenomenon - an abnormal increase of brain tissue volume by the increase of brain tissue water content. However the etiology is not simple and relating to a wide variety of neurological disorders including ischemia, trauma, tumor, hemorrhage and hydrocephalus. It is still a major cause of death in the neurological/neurosurgical ward. This volume is an up-to-date report on progress in brain edema research, diagnosis and treatment, including papers presented at the 12th International Symposium on Brain Edema and Brain Tissue Injury in 2002. Major topics include molecular biology and blood-brain barrier disorders, ischemic and traumatic brain edema, imaging and diagnosis of brain edema, treatment and radiation effect. Various papers in the rapidly growing fields of neuroimaging and molecular medicine are also included.

Advances in epilepsy in recent decades have allowed for improved algorithms for diagnosis and a common understanding of terminology with the development of the International Classifications of Seizures and the Epilepsies. Nevertheless, no common system exists for the estimation of epilepsy severity or its impact on quality of life. Therefore, epileptologists lack the ability to make quantitative assessments of individual patients for comparison of care or for meta-analyses in clinical trials. This book on the Quantitative Assessment of Epilepsy Care approaches this omission by addressing the potential application of clinimetrics within the framework of epilepsy treatment. Clinimetrics is a fast growing discipline concerned with the quantification of clinical symptoms with respect to decision making relating to diagnosis, treatment, and prognosis. These methods allow for the development and validation of clinical scoring systems. For example, the Glasgow Coma Scale is widely used. As a chronic disorder, epilepsy would benefit from clinimetric methodology to create uniformity and to allow for comparisons among evaluations. In addition, epileptologists have not yet developed assessments of health related quality of life to define the overall condition of the chronic epilepsy patient and various therapeutic endpoints. While clini metric tools are essential for research, they will also be useful in clinical practice for the care of individual patients by documenting status and changes over time. This treatise will provide critical analyses of whether existing rating scales and techniques are valid to use, and which types of scales and techniques require further development.

We are most pleased to present Volume 3 of Developmental-Behavioral Disorders: Selected Topics, designed to serve as a companion for standard reference textbooks that address cogent issues in developmental pedi atrics. Periodic publications such as Selected Topics and theme-related articles, as well as continuing education programs, attempt to supple ment in a timely fashion the rapidly changing knowledge base in devel opmental-behavioral pediatrics. These media are important as forums for enhancing the quality of clinical practice, teaching skills, and re search activities. The need is critical for periodically disseminating and updating information about issues in developmental medicine, in as much as this field of study continues to expand at a meteoric pace. During the past several decades, developmental medicine has been recognized as a defined subspecialty in pediatrics. The spectrum of problems encompassed by this discipline is relatively broad and at times clinically overwhelming. The ultimate goal of preventing delays, disor ders, and/or dysfunctions from becoming chronic handicapping condi tions has, by volume per se, created clinical dilemmas for pediatric health care providers. There are numerous facets of providing efficient and effective care, which in the field of developmental-behavioral pediatrics are often exaggerated impediments to the delivery of services by pri mary health care specialists, e. g., time, clinical skills, need for inter disciplinary management, medical-legal responsibilities, financial reim bursements. These issues, as well as clinical problems, are still very much part of the information base to be disseminated to concerned pro fessionals."

This long-awaited second edition has been thoroughly updated and revised by Dr. Michael Salcman with the assistance of Edward R. Laws, MD, Roberto Heros, MD, and Volker Sonntag, MD, yet still preserves the user-friendly aspects of the original book: brevity and ease of practical application in the operating room environment.

Gamma knife radiosurgery has grown continually in importance in recent years. However, there was a lack of established clinical and physical quality standards and a good knowledge of the possibilities of radiosurgical treatment for brain lesions. This book fills the gap by giving an overview of the current status of European gamma knife radiosurgery. Leading european experts report on their specialities in this field which is a state-of-the-art summary of the possibilities and results of their current work. The book encompasses all important as well as the more rare indications. All relevant technical and clinical quality standards are addressed. Tailored planning strategies are described for different indications. All professionals who care for patients with neurosurgical disease, such as neurosurgeons, radiosurgeons, radiologists, radiation oncologists and neurologists will find the book highly useful for the management of patients with benign and malignant brain lesions in a multidisciplinary setting.

As an addition to the European postgraduate training system for young neurosurgeons, we began to publish in 1974 this series of Advances and Technical Standards in Neurosurgery which was later sponsored by the European Association of Neurosurgical Societies. This series was first discussed in 1972 at a combined meeting of the Italian and German Neurosurgical Societies in Taormina, the founding fathers of the series being Jean Brihaye, Bernard Pertuiset, Fritz Loew and Hugo Krayenbuhl. Thus were established the principles of European co operation which have been born from the European spirit, flourished in the European Association, and have been associated throughout with this senes. The fact that the English language is now the international medium for communication at European scientificconferences is a great asset in terms of mutual understanding. Therefore we have decided to publish all contri butions in English, regardless of the native language of the authors. All contributions are submitted to the entire editorial board before publication of any volume for scrutiny and suggestions for revision. Our series is not intended to compete with the publications of original scientificpapers in other neurosurgical journals. Our intention is, rather, to present fields of neurosurgery and related areas in which important recent advances have been made. The contributions are written by specialists in the given fieldsand constitute the first part of each volume."

The small neck of the aneurysm afforded an easy surgical attack. An ordinary flat silver clip was placed over the sac and tightly compressed obliterated it completely. The clip was flush with the wall of the carotid artery. The sac, lateral to the silver clip, was then picked up with the forceps and thrombosed by the electocautery. Walter Dandy reporting his successful operation of a posterior communicating aneurysm on March 23, 1937. Walter Dandy's patient left the hospital in good health 2 weeks later, and from his report one may gain the impression that the operation was an easy task. Despite continuous developments during the following decades, it was not until the introduction of the operating microscope and microsurgical techniques that surgical treatment was generally accepted. During the microsurgical era surgical results have continued to improve due to diagnostical, neuroanaesthesi ological, and microsurgical refinements, and improved neurointensive care. Endovascular obliteration has become an important treatment alternative but this has not been included in this particular volume. The purpose of the present supplement of the ACTA NEUROCHIRURGICA is to review some of the elements in the neurosurgical management of patients with aneurysmal subarachnoid haemorrhage that are important for a successful outcome. Professor Helge Nornes has been a major force in the development of new techniques and research strategies in this area for a number of years and has recently retired from the National Hospital in Oslo."

Surgical skill and imaging technology in the field of neurosurgery have developed remarkably during the past decade. Magnetic resonance imaging (MRI), with high contrast resolution and multiplanar capabilities, allows for accurate preoperative localization and postoperative assessment of syringomyelia. Recent advances in dynamic MRI techniques have made it possible to evaluate normal and abnormal cerebrospinal fluid (CSF) flow at the foramen magnum, within the syrinx, and in the spinal subarachnoid space, without invasion of the closed CSF system. These developments have yielded substantial information concerning various aspects of syringomyelia. However, many issues related to the pathophysiology and treatment of syringomyelia remain controversial. This book contains the scientific contributions presented at the international sym posium "Syringomyelia 2000:' held in Kobe, Japan, June 16-17,2000. The purpose of the symposium was to bring together experts in the fields of neurosurgery, neurol ogy, and neuropathology, in order to enhance the level and scope of their knowledge by making them more aware of work done in complementary fields. The contribu tions also report on clinical and basic studies pertinent to the topic of the sympo sium. This volume thus represents a comprehensive description of the state of the art regarding this disease in the hope that it may help to define comprehensively what is already known and to find new ways toward a better understanding of the patho physiology, diagnosis, and treatment of syringomyelia.

In addition to surgery and radiotherapy, local treatment modalities for the management of brain tumours are increasingly being developed and clinically tested. This book describes for the first time basic tumour biology as well as all current procedures in progress at the most recent level of knowledge, presented by leading experts in the respective fields. Image guided resection procedures, fluorescence guided surgery, developments in interstitial radiosurgery are addressed, just as intracavitary chemotherapy and all current concepts and studies of interstitial targeted therapy. Owing to its topicality this book will remain for long the standard for this comprehensively treated subject.

It is estimated that the functionally significant body of knowledge for a given medical specialty changes radically every 8 years. New specialties and "sub specialization" are occurring at approximately an equal rate. Historically, estab lished journals have not been able either to absorb this increase in publishable material or to extend their readership to the new specialists. International and national meetings, symposia and seminars, workshops, and newsletters success fully bring to the attention of physicians within developing specialties what is occurring, but generally only in demonstration form without providing historical perspective, pathoanatomical correlates, or extensive discussion. Page and time limitations oblige the authors to present only the essence of their material. Pediatric neurosurgery is an example of a specialty that has developed during the past 15 years. Over this period, neurosurgeons have obtained special train ing in pediatric neurosurgery, and then dedicated themselves primarily to its practice. Centers, Chairs, and educational programs have been established as groups of neurosurgeons in different countries throughout the world organized themselves respectively into national and international societies for pediatric neurosurgery. These events were both preceded and followed by specialized courses, national and international journals, and ever-increasing clinical and investigative studies into all aspects of surgically treatable diseases of the child's nervous system."

Pituitary adenomas account for 10-15% of all intracranial tumors and they frequently impair fertility. The development of medical and surgical therapy for such tumors has turned pregnancy into a reality for women harboring pituitary adenomas. However, gestation risks for both mother and fetus are still of concern for endocrinologists, gynecologists and pediatricians. This book intends to update knowledge on this topic, mainly regarding fertility restoration as well as gestational and post gestational management of patients with pituitary tumors.

Because stroke is essentially a disease of the vessels and blood flow, the most fundamental aspects of ischemic blood flow in the brain are under investigation by researchers. Their work was the focus of the sixth in the series of Keio University International Symposia for Life Sciences and Medicine, held in Tokyo in 1999. Selected here are 55 papers from the symposium, covering the buffy coat (glycocalyx) of endothelial cells, the blood-brain barrier and permeability, gene expression, vascular reactivity, dysregulation, inflammatory deterioration, cortical spreading depression, edema, microvascular derangement, and pathology, in ten major sections. The book includes the thought-provoking discussions that followed the presentations, thus providing an invaluable source of up-to-date information not only for researchers investigating microcirculation but also for clinicians implementing the most effective treatment for stroke patients.

Recent breakthroughs in understanding the effectiveness of brain hypothermia treatment have been brought about by rapid progress in experimental gene studies along with new findings in the areas of brain-injury mechanisms, brain thermo-pooling, hemoglobin dysfunction, insulin-resistant hyperglycemia, radical damage involving states of consciousness, management of lipid-dominant metabolism in the intensive care unit (ICU), and management of immune crises under conditions of hypothermia. This book explains the mechanism of brain hypothermia and presents advanced techniques for ICU management of brain hypothermia for critically brain-injured patients. Especially useful for bedside care in the ICU are the easy-reference care-management "cards" in the appendix of the book. Brain Hypothermia Treatment provides a valuable resource and practical guide for professionals in the fields of neurosurgery and emergency and critical care medicine.

The title of this monograph, Brain Tumor Research and Therapy, is the name of the Conference itself, which had its inaugural meeting in the United States in 1975 andhas since progressed to the international scale. In Japan, the first conference ofits kind was organized by Dr. Takao Hoshino and me and was held at Nikko in 1980, hence its name, the Nikko Conference on Brain Tumor Research and Therapy. Though it started as a small, closed meeting, the conference has grown considerably, and in 1992 it was reorganized as the Japanese Conference on Brain Tumor Research and Therapy and was opened to all neurosurgeons and neuropathologists interested in the study of brain tumor problems and who are participating in this field. The main purpose of the Conference on Brain Tumor Research and Therapy is the candid and informed discussion of the most up-to-date developments in basic re search and clinical treatment of brain tumors. The 3rd Japanese Conference on Brain Tumor Research and Therapy was held at Nasu (Tochigi Prefecture), Japan, in No vember 1994. It was a great honor to welcome many distinguished guests from over seas who kindly attended each session and made valuable contributions.

This 'in vivo' atlas contains more than 50 magnetic resonance (MR) images of the brain. Each structure is represented in the axial, coronal and sagittal plane, magnified in colour schemes and reconstructed in 3D images with a useful millimetric scale. The atlas offers the reader a practical and simple tool for surgical planning and for diagnostic and anatomical studies. The high level of anatomical definition of the in vivo MR images means that there is no loss in precision as a result of post-mortem changes. No doubt, this book is an excellent teaching instrument for all students of the neurosciences, regardless of the individual level of training and expertise.

Some 29 scientists from the fields of neuroanatomy, neurochemistry, neu rophysiology, neuropharmacology, and behavior have contributed their ef forts to this testimonial on behalf of the contributions made by Dr. F. W. L. Kerr to science and to those with whom he interacted. The intention of the contributors to this volume was to deal with the manifold advances that pertain to the substrates in spinal cord relating to the processing of sensory infor mation, a subject that in one form or another provoked time and again Kerr's native enthusiasm for research. The organization of the book follows a natural course from the peripheral innervation of the somatic and visceral organs (Winkelmann, Chapter 2) to the effective stimuli that activate these fibers and give rise to sensation under normal and pathological conditions (Campbell and Meyer, Chapter 3; Dubner and colleagues, Chapter 13; Dyck, Chapter 14) to the course these afferent systems take to enter the spinal cord (Coggeshall, Chapter 4) and to the organization of the systems through which this afferent information reaches the brain (Willis, Chapter 11; Vierck and colleagues, Chapter 12)."

The fact that the English language is well on the way to becoming the international medium at European scientific conferences is a great asset in terms of mutual understanding. Therefore we have decided to publish all contributions in English, regardless of the native language of the authors.

Our series is not intended to compete with the publications of original scientific papers in other neurosurgical journals. Our intention is, rather, to present fields of neurosurgery and related areas in which important recent advances have been made. The contributions are written by specialists in the given fields and constitute the first part of each volume. In the second part of each volume, we publish detailed descriptions of standard operative procedures, furnished by experienced clinicians; in these articles the authors describe the techniques they employ and explain the advantages, difficulties and risks involved in the various procedures. This part is intended primarily to assist young neurosurgeons in their post graduate training. However, we are convinced that it will also be useful to experienced, fully trained neurosurgeons."

In August of 1991, a second Dartmouth International Workshop on the corpus callosum was convened to share and discuss the progress that had been made over the decade that had passed following the first workshop. A nucleus of basic and clinical scientists came together to discuss their work and the work of others in a field that has been broadened clinically by the addition of many new centers throughout the world that are now performing corpus callosotomy for intractable epilepsy. This text was stimulated by the participants' presentations and associated fertile discussions. It is compiled from the conference and subsequent studies. It reflects, both at the basic and clinical level, an important and expanding field of neural science endeavor. In keeping with the present and rapidly expanding field of outcomes assessment, callosotomy is again evaluated in light of a further decade of surgery and follow-up. Callosotomy continues to be a useful, palliative procedure and the indications for its use have been better established. The basic science section is a supplement to the first edition and elaborates progress in both new data and ideas. The section on experimental epilepsy models adds further support to the clinical rationale for callosotomy. Perhaps of greater importance is the contribution of experimental models to our understanding of the propagation of seizure activity. The section on the neuropsychology of the split brain patient demonstrates the continuing major contributions to the understanding of brain and behavior that pour forth from this cornucopia.

The intracarotid amobarbital (or Amytal) procedure is commonly referred to as the Wada test in tribute to Juhn Wada, the physician who devised the technique and performed the fIrst basic animal research and clinical studies with this method. Wada testing has become an integral part of the pre operative evaluation for epilepsy surgery. Interestingly, however, Wada initially developed this method as a technique to assess language dominance in psychiatric patients in order that electroconvulsant therapy could be applied unilaterally to the non-dominant hemisphere. Epilepsy surgery has matured as a viable treatment for intractable seizures and is no longer confmed to a few major universities and medical institutes. Yet, as is increasingly clear by examining the surveys of approaches used by epilepsy surgery centers (e.g., Rausch, 1987; Snyder, Novelly, & Harris, 1990), there is not only great heterogeneity in the methods used during Wada testing to assess language and memory functions, but there also seems to be a lack of consensus regarding the theoretical assumptions, and perhaps, even the goals of this procedure.
