This text contains the scientific contributions to the Fourth International Symposium on Sphingolipids, Sphingo lipidoses and Allied Disorders held at the Kingsbrook Jewish Medical Center on October 25-27, 1971. These meetings were conducted under the auspices of the Isaac Albert Research Institute of the Kingsbrook Jewish Medical Center and the National Tay-Sachs and Allied Diseases Association, Inc. Four symposia, held in 1958, 1961, 1965 and 1971 were designed to gather the most relevant and innovative of the laboratory and field studies concerned with these hereditary disorders. The texts generated by these periodic meetings have mirrored the increasing absorption of the scientific community in the problems of sphingolipid metabolism. The first meeting in 1958 consisted of but twelve pre sentations, the majority emanating from local laboratories. The current sessions contain 48 scientific presentations by scientists from nine countries and demonstrate the increas ingly diversified techniques and approaches employed in the study of these diseases. Many of the authors, in exploring data on the mucopolysaccharidoses and leucodystrophies, as well as the sphingolipidoses, have given recognition to those biochemical areas held in common by these otherwise diverse disease processes. The problems of prevention and therapy of these diseases have been considered by some of the contributors. Laboratory screening procedures designed to detect carriers of the va rious lipidoses are now available and the experiences of some laboratories in this area are summarized within this volume. The prospective identification of heterozygotes may indeed become a powerful adjunct in genetic counseling.

The present volume contains the scientific contributions to the Fifth International Symposium on "Current Trends in Sphingo lipidoses and Allied Disorders" under the auspices of the Isaac Albert Research Institute of the Kingsbrook Jewish Medical Center, the Department of Pathology, Downstate Medical Center, State Uni versity of New York, Brooklyn, New York, and the National Tay-Sachs and Allied Diseases Association, Inc., New York. A review of the four previous Symposia shows the increase in scope of the scientific exploration in this rapidly expanding field. The first meeting, held in 1958, was devoted to the discussion al most entirely of Tay-Sachs disease. The majority of the work emanated from local laboratories. The participants at the present Symposium came from many other domestic and foreign research in stitutions. The scope of the papers presented at these meetings and the interest shown in the Symposium demonstrates the signifi cance attached by the scientific community to the problems of these hereditary diseases. The reasons for this are apparent, when one considers the contributions during recent years to our basic know ledge by lipid and enzyme chemistry, genetics, and neuropathology. Partly because of the hereditary nature of these diseases any new discovery in this field has general meaning and permits cautious generalization well beyond its clinical significance.

Cerebral Sphingolipidoses: A Symposium on Tay-Sach's Disease and Allied Disorders is a collection of papers presented at the 1961 Symposium on the Cerebral Sphingolipidoses, held in Isaac Albert Research Institute of the Jewish Chronic Disease Hospital and the Downstate Medical Center of the State University of New York. The contributors demonstrate the significance attached to an intensive study of Tay-Sach's and allied diseases. A unique feature of the Symposium was the constant awareness of the clinical implications of the fundamental studies presented. This book is organized into three sections encompassing 30 chapters. The first part deals with the morphological aspects of cerebral lipidoses, including the diagnosis, biopsy, pathology, and clinical features of these diseases. This part also provides case reports of specific cerebral sphingolipidoses. The second part highlights the biochemical aspects of Tay-Sach's and allied disorders. This part specifically looks into the mechanism of abnormal lipid metabolism, chemical pathology of lipids, and quantitative fractionation of complex lipid mixtures. This part also considers the characterization of accumulated gangliosides in brain, which is one the most striking features in infantile amaurotic idiocy, a type of Tay-Sach's disease. The third part explores the genetic and therapeutic aspects of the sphingolipidoses. This book will be of value to lipid chemists, geneticists, biochemists, neuropathologists, and clinicians.

Inborn Disorders of Sphingolipid Metabolism is a collection of papers presented at the Third International Symposium on the Cerebral Sphingolipidoses and Allied Diseases, held at the Isaac Albert Research Institute of the Jewish Chronic Disease Hospital and at the State University of New York, Downstate Medical Center, on October 25 and 26, 1965. This book is organized into three parts encompassing 35 chapters. Part I deals first with electron microscopic, histochemical, and morphological investigations of certain sphingolipid metabolism disorders. This part also examines several case reports on the features and symptoms of spongy degeneration of the central nervous system, familial leukodystrophy, adrenal insufficiency, and cutaneous melanosis. Part II surveys the metabolism, biosynthesis, and structure of gangliosides and sialic acids. This part also considers the nature of the lipophilic portions of the brain gangliosides. This part particularly looks into the features and clinical manifestation of Tay-Sachs disease. The third part covers the genetic and clinical aspects of the Tay-Sachs disease. This part also evaluates the genetics of the Hurler-Hunter syndrome, Batten-Spielmeyer-Vogt disease, and lipogranulomatosis syndrome. This book is of value to biochemists, histochemists, geneticists, and researchers in the allied fields of lipidosis.

This volume in the 5-Minute Consult series focuses on neurological diseaes and disorders, as well as key symptoms, signs, and tests. Dozens of noted authorities provide tightly organized, practical guidance. Using the famous two-page layout and outline format of The 5-Minute Consult Series, the book provides instant access to clinically-oriented, must-have information on all disorders of the nervous system. Each disease is covered in a consistent, easy-to-follow format: basics (including signs and symptoms), diagnosis, treatment, medications, follow-up, and miscellaneous considerations (including diseases with similar characteristics, pregnancy, synonyms, and ICD coding).

The book presents a detailed and authoritative exposition of the basic principles and applications of biochemistry. It thouroughly covers the syllabus recommended by MCI for undergraduate medical students. It focuses primarily on the fundamental concepts and explain them in detail. Numerous line diagrams, in an attractive two-colour format, are provided to illustrate the concepts and help the students in grasping their significance. Medical applications of biochemistry are discussed through extended examples and clinical cases.
