Book SynopsisNeurology is primarily characterized by a variety of diseases which seem very similar and are therefore difficult to distinguish between. Skill at differential diagnosis is therefore absolutely paramount. Neurological Differential Diagnosis is a streamlined handbook of prioritized differential diagnosis, to be used both in clinical practice and for exam review. By presenting differential diagnosis in order of frequency and importance, this book provides a practical handbook for clinicians in training, as well as a potential resource for quick board review. Whilst the book covers the most important syndromes and disease entities, readers are referred to other texts for more exhaustive differentials. By limiting differentials in this way - to the most likely and most serious diagnoses - the reader can more easily recall relevant disease processes when faced with a particular clinical situation, whether it be a patient in the emergency room or a diffTrade Review"This is a "pearl" of a book for any clinician who is asked to assess patients with symptoms or signs suggestive of a neurological disorder, including neurologists, internists, geriatricians, neurosurgeons, psychiatrists, general practitioners, trainees, and students. Neurological Differential Diagnosis will enlighten clinicians on the most likely and important differential diagnoses to consider and exclude, and guide appropriate and cost-effective investigations. The book has a unique format; it is the only book I know to list differential diagnoses according to what is most common in patients of the same demographic and what is potentially the most lethal and disabling. This hierarchy of differential diagnoses is clearly and consistently presented (eg, in bold and italicised text) throughout the book. Associated relevant background information for each symptom, syndrome, or disorder is well presented (in shaded boxes) with the list of differential diagnoses. Welcome chapters on paediatric neurology, neurogenetics, neuroradiology, diagnostic tests, neuroanatomy, and neuropathology are included. Although few references are given, the book seems to be valid, based on a wealth of clinical experience coupled with best evidence from the available literature. Even after practising clinical neurology for more than 20 years, I have already dipped into this book on several occasions to help me with tricky patients, and I have to remind my neurology residents and registrars, and colleagues in the accident and emergency department, to return it." --Graeme J Hankey (The Lancet Neurology, Vol 4 November 2005)Table of ContentsForeword.

Book SynopsisDespite public perception, osteoporosis remains a widespread, devastating disease, and a very serious and costly public health threat. Early detection and treatment must be a priority for primary health care providers. Dual-energy X-ray absorptiometry (DXA) is the principal x-ray technology used to diagnose osteoporosis in its early, asymptomatic stages, to assess treatment efficacy, and to guide treatment decisions. It remains the gold standard today.

Book SynopsisEarly hearing detection and intervention (EHDI) is the gold standard for any practising audiologist, and for families of infants and children with hearing impairment. EHDI programmes aim to identify, diagnose and provide intervention to children with hearing impairment from as early as six months old (as well as those at risk for hearing impairment) to ensure they develop and achieve to their potential. Yet EHDI remains a significant challenge for Africa, and various initiatives are in place to address this gap in transferring policy into practice within the southern African context.The diversity of factors in the southern African context presents unique challenges to teaching and research in this field, which has prompted this book project. The South African government's heightened focus on increasing access to health care which includes ongoing Early Childhood Development (ECD) programmes, make this an opportune time for establishing and documenting evidence-based research for current undergraduate and postgraduate students. Early Detection and Intervention in Audiology: An African Perspective aims to address this opportunity.Grounded in an African context with detailed case studies, this book provides rich content that pays careful attention to contextual relevance and contextual responsiveness to both identification and intervention in hearing impairment. With diverse contributions from experts in local and international contexts, but always with an African perspective, this is textbook will be an invaluable resource for students, researchers and practitioners.Table of Contents List of illustrations Abbreviations and acronyms Acknowledgements Section One: Early Detection of Hearing Impairment Chapter 1 A Paradigm Shift in Early Hearing Detection and Intervention in South Africa - Amisha Kanji and Katijah Khoza-Shangase Chapter 2 Exploring Early Detection of Hearing Impairment in Sub-Saharan Africa - Amisha Kanji Chapter 3 Approaches to Early Detection of Hearing Impairment in Low and Middle-Income Countries - Amisha Kanji Chapter 4 Implementing Early Hearing Detection in the South African Health Care Context - Luisa Petrocchi-Bartal, Katijah Khoza-Shangase and Amisha Kanji Chapter 5 Confronting Realities to Early Hearing Detection in South Africa - Katijah Khoza-Shangase Chapter 6 Contextualisation of Risk Factors for Hearing Impairment - Jane Fitzgibbons, Rachael Beswick and Carlie Driscoll Section Two: Early Intervention for Hearing Impairment Chapter 7 Approaches to Early Intervention for Hearing Impairment - Amisha Kanji and Aisha Casoojee Chapter 8 Models of Care in Early Intervention for Children with Hearing Impairment - Amisha Kanji Chapter 9 Continuity of Care at School for the Hearing-Impaired Child - Katijah Khoza-Shangase SECTION THREE: COMPLEXITIES OF EARLY HEARING DETECTION AND INTERVENTION Chapter 10 Sensory Impairments in Early Hearing Detection and Intervention - Nomfundo F.

Book SynopsisToday most of immunochemistry methods for the determination of proteins, peptides, drugs, and many small molecules are fully automated, with good precision, excellent sensitivity and short reaction time. However, inaccuracy due to poor standardization and the presence of interfering substances in biological samples is still a serious and life-threatening issue. Proper validation of methods and quality assurance have little effect on frequency of occurrence of false positive or false negative results, which, if unrecognized, may lead to patient's misdiagnosis, unnecessary treatment or even unnecessary surgery. Deep knowledge of basic principles of immunochemical methods (antigen-antibody reaction, standardization, matrix effect, limit of detection, cross-reactivity, etc.), sources of analyte-independent interferences (preanalitycal errors, the presence of binding proteins, the presence of autoantibodies) and analyte-dependent interferences (presence of heterophilic antibodies, high-dose effect) are very important to understand, detect, reduce and/or eliminate the interferences. This book helps to reduce false results and, at the same time, improve patient's care and patient's safety.Table of ContentsImmunodiagnostics and patient safety Table of contents1.

Book SynopsisBlood transfusion is considered a life-saving therapy since ancient times, but, at the same time, a high-risk procedure. Nowadays the common perception is that infection is the greatest risk, even if the blood has never been safer from this point of view. Currently, the residual risk of transfusion must be related mainly to immunological mechanisms underlying to AB0 and minor blood systems, to compatibility of blood transfused and to development of irregular antibodies in transfused patients. "Transfusion Medicine and Patient Safety" aims to provide the basic of immunohematology to readers and to analyze the transfusional process highlighting the most critical points, thus more exposed to errors. Screening on blood and blood components for infectious diseases along with the surveillance action on emerging viruses results in the drastic reduction of post-transfusion infection, together with the potential to further increase the level of security from infection through the inactivation of blood components.The text also describes the major diagnostic systems and organizational models that modern technology provides us with a correct immunohematological diagnosis and an appropriate trasfusional therapy.

Book SynopsisHow Doctors Think defines the nature and importance of clinical judgment. Although physicians make use of science, this book argues that medicine is not itself a science but rather an interpretive practice that relies on clinical reasoning. A physician looks at the patient''s history along with the presenting physical signs and symptoms and juxtaposes these with clinical experience and empirical studies to construct a tentative account of the illness.How Doctors Think is divided into four parts. Part one introduces the concept of medicine as a practice rather than a science; part two discusses the idea of causation; part three delves into the process of forming clinical judgment; and part four considers clinical judgment within the uncertain nature of medicine itself. In How Doctors Think, Montgomery contends that assuming medicine is strictly a science can have adverse side effects, and suggests reducing these by recognizing the vital role of clinical judgment. This is a book that wiTable of ContentsPART I. MEDICINE AS A PRACTICE ; 1. Medicine and the Limits of Knowledge ; 2. The Misdescription of Medicine ; PART II.
