Pathology Of Skeletal Muscle

This book has been described as the bible of muscle disease, from both a scientific and a clinical point of view. It is a comprehensive work that explains and illustrates in detail all pathological reactions of skeletal muscles that occur in human disease. The microscopic changes are illustrated by histochemistry, immunocytochemistry, resin histology, and electron microscopy. The pathological findings are correlated with the clinical picture whenever possible. The interpretation of the findings is scientifically based. To facilitate this process, the fundamentals of normal histology and biology of the muscle cell are also covered.The book has been thoroughly revised and expanded for this Second Edition to provide up-to-date coverage of the relevant molecular biology and molecular genetics, as well as extensive references. It has been well organized and richly illustrated by the authors, who have been at the forefront of muscle pathology and neuromuscular research for 35 years. This practical reference work is intended for neuropathologists, neurologists, and general pathologists who look at muscle biopsies. It will also serve as an introduction to muscle disease for neurology and pathology residents.

Aimed at the diagnostic pathologist and neurologist, this text is organized by disease, with introductory chapters on morphology, immunology, pathogenesis and biopsy technique. The second edition includes information on pathogenesis of muscle disease.

Metabolic and functional impairments in skeletal muscle occur frequently, often in diverse conditions and each with different aetiologies, methods of diagnosis and treatment. This comprehensive text brings the complex facets of skeletal muscle pathology, diagnosis and management together.

With the advent of enzyme histochemistry, which this field and simplistic theories will be expanded or revealed hitherto unseen pathological differences discarded. between muscle disorders, muscle biopsy assumed Diseased muscle cells, as any other cell type, show an important diagnostic role. The investigation is easily only limited morphological changes. However bizarre, performed and is being undertaken with increasing very few of these changes, if any, are pathognomonic of frequency. Nevertheless there is still a tendency to a single disease. The exact significance of microscopic regard its interpretation as highly specialized and out findings is to a large extent determined by their clinical side the province of the general histopathologist. In this context. Thus, although this is an atlas, it is definitely atlas I have tried to lift the veil of neuropathological not designed to promote 'spot' histological diagnoses.

This book covers all aspects of basic, essential, recent advances and controversies in myopathology. The major emphasis is on diagnostic myopathology of muscular dystrophies, inflammatory myopathies, mitochondrial myopathies, metabolic myopathies, congenital myopathies, myopathies of miscellaneous etiology, neurogenic and neuromuscular junction disorders, the goal being to broaden readers’ understanding of individual disease subgroups. The book also contains all the essential details needed to establish a neuromuscular lab, making it especially relevant for laboratory technical staff and research scholars.

The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.
