Book excerpt: Objectifs: Etudier la valeur de l'IRM pour déterminer l'heure de début de l'accident vasculaire cérébral ischémique à la phase hyperaiguë et le pronostic fonctionnel à moyen terme des patients. Matériel et méthodes : Nous avons mené une étude rétrospective sur 55 patients présentant un AVCI avec heure de début connue et traités par thrombolyse. Une IRM encéphalique avec séquence de diffusion et FLAIR a été réalisée dans les 6 premières heures. Les signes d'ischémie en diffusion et en FLAIR ont été évalués de façon qualitative. Une analyse quantitative a été réalisée sur les paramètres d'IRM suivants : ratio de coefficient apparent de diffusion (ADC) et ratio FLAIR entre la zone ischémique en hypersignal et une région miroir symétrique de l'hémisphère controlatéral sain et volume lésionnel en diffusion et en FLAIR. La corrélation entre ces données d'imagerie et l'heure de début des symptômes a été évaluée. Les données d'IRM des 40 patients pris en charge dans les 3 premières heures ont été comparées à celles des 15 patients pris en charge entre 3 et 6 heures en utilisant une régression logistique multivariée et un test t de Student. Une analyse a été faite selon deux groupes d'évolution clinique à 3 mois selon le score de Rankin (mRS entre 0 et 2, mRS entre 3 et 6). Résultats: Nos résultats ne montrent pas de lien statistiquement significatif entre les variables quantitatives (ratio ADC, ratio FLAIR et volume lésionnel) et l'ancienneté de l'AVCI. Le score ASPECT en diffusion est statistiquement différent dans les deux groupes 0-3 heures et 3-6 heures en utilisant un test t de Student, (p = 0,02) et une régression logistique multivariée (p = 0,04). On ne trouve pas de différence significative entre les autres paramètres d'IRM dans les deux groupes. Notre étude décèle comme prédictifs de l?évolution clinique, les facteurs suivants : le score ASPECT en diffusion, le volume de la zone de nécrose initiale en diffusion, le ratio moyen du coefficient de diffusion et la présence d'hypersignaux intraartériels en FLAIR. Conclusion: Dans notre population, nous avons retrouvé des signes précoces d'ischémie en diffusion et en FLAIR chez tous les patients, sauf chez un cas où la séquence FLAIR est normale. L'IRM n'a pas permis de déterminer l'heure de début des symptômes dans les 6 premières heures ou de séparer les AVC datant de moins de 3 heures de ceux survenus entre 3 et 6 heures. Enfin, notre étude apporte des éléments prédictifs de l'évolution clinique et de la survie sans dépendance après thrombolyse.

Available in PDF, EPUB and Kindle. Book excerpt: 2004 BMA Medical Book Competition Winner (Radiology category) “This is an exciting book, with a new approach to use of the MRI scanner. It bridges the gap between clinical research and general neuro-radiological practice. It is accessible to the clinical radiologist, and yet thorough in its treatment of the underlying physics and of the science of measurement. It is likely to become a classic.” British Medical Association This indispensable 'how to' manual of quantitative MR is essential for anyone who wants to use the gamut of modern quantitative methods to measure the effects of neurological disease, its progression, and its response to treatment. It contains both the methodology and clinical applications, reflecting the increasing interest in quantitative MR in studying disease and its progression. The editor is an MR scientist with an international reputation for high quality research The contributions are written jointly by MR physicists and MR clinicians, producing a practical book for both the research and medical communities A practical book for both the research and medical communities “Paul Tofts has succeeded brilliantly in capturing the essence of what needs to become the future of radiology in particular, and medicine in general – quantitative measurements of disease.” Robert I. Grossman, M.D. New York, University School of Medicine (from the Foreword)

Available in PDF, EPUB and Kindle. Book excerpt: Body MRI: Cases in Radiology serves as a ready reference of 141 cases and nearly 900 superb quality images of common and uncommon conditions encountered in the daily practice of body MRI. The book is specifically intended for radiology residents and fellows as a study guide to broaden clinical knowledge and improve diagnostic skills when reviewing MR images of the liver, biliary system, pancreas, urinary tract, adrenal glands, peritoneal cavity, spleen, gastrointestinal system, female genital tract, vascular system, and heart. The selected cases provide outstanding examples of various disease states and their appearances as demonstrated by MR imaging using a variety of pulse sequences. Each case is shown on the front page with a brief clinical history and multiple, carefully selected images that best show the important findings. When turning the page, the imaging findings, differential diagnosis and important teaching points are given in bullet-point format facilitating the learning process and allowing the reader to improve interpretation and diagnostic capability in body MRI. Cases are presented in random order to mimic the diagnostic challenges that typically occur when reading the daily worklist of cases in a routine clinical body MRI practice. Readers can also review the cases by organ system through the Index of Cases found in the back of the book. Body MRI Cases is also an excellent companion study guide to Essentials of Body MRI by the same authors. Together, these texts provide an excellent foundation in Body MRI.

This book was released on 2019 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plum and Posner's Diagnosis and Treatment of Stupor and Coma, 5th edition, is a major update of the classic work on diagnosing the cause of coma, with the addition of completely new sections on treatment of comatose patients, by Dr. Jan Claassen, the Director of the Neuro-ICU at Columbia New York Presbyterian Hospital. The first chapter of the book provides an up-to-date review on the brain mechanisms that maintain a conscious state in humans, and how lesions that damage these mechanisms cause loss of consciousness or coma. The second chapter reviews the neurological examination of the comatose patient, which provides the basis for determining whether the patient is suffering from a structural brain injury causing the coma, or from a metabolic disorder of consciousness. The third and fourth chapters review the pathophysiology of structural lesions causing coma, and the specific disease states that result in coma. Chapter five is a comprehensive treatment of the many causes of metabolic coma. Chapter 6 review psychiatric causes of unresponsiveness and how to identify and treat them. Chapters 7 and 8 review the overall emergency treatment of comatose patients, followed by the treatment of specific causes of coma. Chapter 9 examines the long term outcomes of coma, including the minimally conscious state and the persistent vegetative state, and how they can be distinguished, and their implications for eventual useful recovery. Chapter 10 reviews the topic of brain death and the standards for examination of a patient that are required to make the determination of brain death. The final chapter 11 is by J.J. Fins, a medical ethicist who was invited by the other authors to write an essay on the ethics of diagnosis and treatment of patients who, by definition, have no way to approve of or communicate about their wishes. While providing detailed background for neurological and neurosurgical specialists, the practical nature of the material in this book has found its greatest use among Internists, Emergency Medicine, and Intensive Care specialists, who deal with comatose patients frequently, but who may not have had extensive neurological training.

Available in PDF, EPUB and Kindle. Book excerpt: Audiological medicine is a relatively new specialty spanning the investigation, diagnosis and medical management of hearing and balance disorders. Recent years have seen its growth as a separate medical discipline, although its practice depends not only upon a clear understanding of the basic sciences relevant to auditory and vestibular function, but also upon experience and knowledge in a wide range of clinical disciplines relevant to hearing and balance disorders, including genetics, immunology, pediatrics, geriatrics, neurology, otolaryngology, ophthalmology, psychiatry and general internal medicine. A Textbook of Audiological Medicine integrates the science and medicine of auditory and vestibular disorders, providing the first comprehensive textbook on the subject. There are five main sections; the first deals with both the auditory and vestibular systems, and then each system is considered in terms of the relevant basic sciences and clinical disorders.
