Silver in healthcare has many different facets and since the early concepts of microbiology of the 1880's, has been developed from usage in surgical clips, staples, foil wound dressings and surgical implants, to the widespread and clinically effective antiseptic wound dressings, sutures, catheters, bone and dental implants, and cardiovascular devices of today. From the dawn of human civilisation, silver has had a role of water purification and even now has a role in hospital water systems for control of MRSA and legionnaires disease. Biotechnological advances in recent years have extended the antimicrobial properties of silver into production of hygiene textiles and use in domestic products. Important advances have been made in understanding mechanisms of antimicrobial action of silver, the central importance of ionisation patterns in the presence of body fluids and secretion, and the genetical and molecular profiles of silver resistance. This publication is a comprehensive account of the history of silver in medicine, its clinical benefits and wide advantages as a broad spectrum antimicrobial agent. It is clear from the extensive array of publications in recognised and unofficial press, that many misconceptions and misleading conceptions have been perpetuated, leading to errors in evaluation of the safety of the metal in occupational, domestic and therapeutic situations. The book is unique in that it is the only comprehensive presentation of the toxicology of silver and it identifies the major misconceptions in the safety of silver and interpretation of argyria and argyrosis as central features of silver toxicity. In this book, Dr Lansdown reviews the literature from a clinical and experimental viewpoint, with the benefit of his many years research on silver and experience gained in working with clinicians, healthcare product manufacturers and microbiologists. There is also discussion in the book on the relevance of antimicrobial resistance to silver and deficiencies in present day clinical practice in not evaluating incidences of resistance on a routine basis. The subject matter is presented in a readable fashion and includes reference to use of the metal in such practices as acupuncture and treatment of tropical diseases as practised in some parts of the world, each of which is accompanied by special clinical risk. It is also a collation of current views on the use and efficacy of silver as a broad spectrum antibiotic. The chapters which deal specifically with toxicological aspects of silver in clinical, occupational and environmental issues are central to the book's value. The book is aimed at clinicians, research scientists and product manufacturers and will provide ideas for new research and academic endeavour. It is also essential reading for research students with an interest in metal toxicity and its management in mammalian tissues.

This book re-evaluates epidemiological and occupational health studies, experimental studies in animals and in vitro experiments relating to the toxicity of 27 metal and metalloid elements for which evidence of carcinogenicity has been presented. Human carcinogenic risk is substantiated in relation to arsenic, beryllium, thorium, chromium, radioactive elements, probably lead, and some nickel and cobalt compounds, and respirable silica particles, but the carcinogenicity of iron, aluminium, titanium, tungsten, antimony, bismuth, mercury, precious metals, and certain related compounds in humans is unresolved. The toxicity and carcinogenicity of each element is specific but correlates poorly with its position in the Periodic Table. Carcinogenicity differs according to the valency of the ion and its ability to interact with and penetrate membranes in target cells and to bind, denature or induce mutations by genotoxic or epigenetic mechanisms.This important text comprehensively examines each of the elements providing detailed information on the carcinogenicity and toxicity and detailing the most up-to-date research in this area. The book is an essential tool for toxicologists, medicinal and biochemists, and environmental scientists working in both industry and academia.
