The books in this series are the results of international headache seminars held each November. The present book is from the 4th International Headache Research Seminar, where the usefulness of classification systems and operational diagnostic criteria were emphasized. Headache Classification and Epidemiology is divided into an introduction and six sections, each of them ending with a discussion summary. The first section deals with the general principles of disease classification and diagnosis, symptoms, and interobserver reliability. In this section, it is suggested that changes in the International Headache Society (IHS) criteria be made gradually and on the basis of solid published data, and that IHS criteria be combined with International Classification of Disease, 10th edition (ICD-10) codes. The conclusion is that the diagnosis of migraine and tension-type headaches can be made with low interobserver variability. The second section is devoted to the classification and diagnosis of primary headaches; migraine, tension-type, and drug-induced headaches are analyzed. In the particular case of migraine, one of the most important issues discussed is the debate over whether “migraine with aura” and “migraine without aura” are actually different conditions. The third section is dedicated to secondary headaches, paying special attention to posttraumatic and stroke-related headaches. Posttraumatic headache remains a very controversial condition, but there seems to be an agreement that the severity of the head injury is not related to either the severity of the headache or its duration. Section four deals with general principles of epidemiology; the validity of questionnaires in headache research is questioned. The conclusion is that the only method which fulfills the IHS criteria is a face-to-face interview with a neurologist. However, questionnaires should be the first step toward selecting individuals to undergo more sophisticated evaluation. The fifth section provides some epidemiologic studies of headache, focusing on the United States and some European countries, as well as on headache in children. The last section is devoted to sociodemographic and psychosocial factors. We must commend the editor for his efforts to ensure that the book contains up-to-date information on contemporary topics in headache and is written by worldwide specialists. It is difficult today to obtain this much quality information compiled in

this manner. This book is a good compromise between quality and quantity, which is difficult to find in other sources. It is noteworthy that every discussion summary emphasizes the most interesting and controversial issues in current headache assessment, classification, and epidemiology.

BRAIN TUMORS: A COMPREHENSIVE TEXT. Edited by Robert A. Morantz and John W. Walsh 864 pages. $215.00. New York: Marcel Dekker, Inc., 1994. ISBN O-8247-88265 It is obvious that the brain tumor is one of the major disorders managed by neurosurgeons, and the number of patients has been gradually increasing recently in almost all countries in the world. The diagnostic methods and therapeutic modalities are also steadily changing and improving. Although many monographs dealing with the pathology and molecular biology of brain tumors or specific tumors such as glioma, meningioma, pituitary adenoma, or third ventricular tumors have been published in recent years, there has been no up-to-date, comprehensive text on the subject of brain tumors. This text, edited by Drs. Robert A. Morantz and John W. Walsh, is a very well organized and useful text covering all aspects of brain tumors. Although no remarkable advancement in biologic research and therapeutic modalities had been achieved during almost half a century after the pioneering works by Cushing and others in the beginning of 20th century, revolutionary changes were realized in the 1970s in the imaging diagnosis of brain tumors by the development of computed tomography scan and in surgical techniques by introducing microscopes. Surgical techniques to remove skull base tumors and the stereotactic management for biopsy, local radiosurgery, or brachytherapy for treating various brain tumors have developed and have extensively improved the outcome for patients with brain tumors. This text covers precisely those new fields of brain tumor treatment. With the introduction of many useful illustrations and figures, the readers can easily understand such procedures and their results. Even in cases of malignant brain tumors, germinoma and medulloblastoma are two examples of tumors that have showed dramatic improvement in
