Available in PDF, EPUB and Kindle. Book excerpt: @Il existe dans l’environnement du cabinet dentaire et autour de l’unit dentaire différentes sources de contamination. Elles sont représentées par le praticien, son personnel, le patient, l’eau provenant de l’unit dentaire et l’air. L’eau constitue un élément essentiel dans la réalisation des soins dentaires. La concentration bactérienne de l’eau contenue dans les units dentaires est supérieure à celle du réseau de distribution d’eau potable dont elle est issue. Ces microorganismes proviennent essentiellement du biofilm qui se forme à l’intérieur des conduits d’eau des units dentaires. L’activité au fauteuil va générer plusieurs voies de dissémination des germes pathogènes et donc divers types de transmission. L’utilisation de l’instrumentation dynamique va précipiter dans l’air un grand nombre de micro-organismes. La formation des bioaérosols aura pour conséquence directe un risque pour le personnel soignant et les patients mais aussi comme conséquence indirecte le développement d’un biofilm multi-bactérien sur une surface inerte. Les mains vont donc jouer un rôle primordial dans la chaîne de transmission des germes et par conséquent dans la propagation des infections. La contamination de l’eau des units dentaires représente un risque pour le patient, le praticien et le personnel. Le chirurgien dentiste et son personnel ont le devoir et l’obligation d’appliquer toutes les mesures d’hygiène nécessaires pour prévenir la transmission des infections. Différents moyens de lutte contre les agents infectieux sont à la disposition des professionnels de santé pour éviter le risque de contamination au cabinet dentaire.

Book excerpt: La première partie de la thèse est consacrée à l'énoncé et à la critique des diverses techniques microbiologiques utilisées pour étudier la plaque sous-gingivale et sa pathogénécité. La deuxième partie est plus spécialement consacrée aux études de cette flore, réalisée par M. Listgarten et son équipe, à l'aide du microscope à fond noir. La troisième partie rend compte d'une recherche personnelle qui a été effectuée au sein d'une équipe, à l'Hôpital de Tonnerre où 2952 échantillons de plaque sous-gingivale prélevée sur 30 patients ont été temporairement examinés au microscope à fond noir. L'originalité de notre recherche se situe à deux niveaux : l'élaboration d'un protocole expérimental commun à plusieurs recherches bien spécifiques mais complémentaires, et l'utilisation d'une méthode statistique tout à fait nouvelle en Sciences Odontologiques. Nous sommes arrivées, à la fin de cette expérimentation, aux résultats suivants : La pathologie la plus avancée d'une bouche se trouve statistiquement au niveau des faces proximales des molaires ; l'ordre d'apparition des populations bactériennes de l'état sain à pathologique suit une chronologie précise : les "autres" seraient une population charnière entre l'état sain et pathologique ; la profondeur de poche et l'indice de plaque semblent préfigurer l'indice gingivale : la profondeur de poche semble être un indice transitoire entre l'indice de plaque et l'indice gingivale.
Download or read book L Eau comme vecteur de contamination au cabinet dentaire written by Florie Laval and published by . This book was released on 2003 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'eau est un élément largement utilisé au cabinet dentaire. Sa qualité microbiologique dans les équipements dentaires est d'une importance considérable car les patients et les membres de l'équipe y sont régulièrement exposés. La caractéristique unique de l'unit est sa capacité à développer rapidement des biofilms bactériens sur les conduites d'approvisionnement en eau. Ces biofilms sont alimentés par les germes contenus en faible quantité dans l'eau d'arrivée et ceux de la bouche du patient rétractés pendant les soins. L'eau de l'unit dentaire et notamment les aérosols produits lors des traitements, peuvent alors être fortement contaminés par des pathogènes opportunistes et dépassent souvent les paramètres microbiologiques de potabilité. Actuellement, il n'existe pas de réelle preuve scientifique concernant un quelconque lien entre exposition à l'eau contaminée et infection. Cependant avec l'augmentation des personnes fragilisées, appliquer le principe de précaution semble souhaitable; ceci dans un cadre d'amélioration de la qualité des soins au cabinet. Par ailleurs, le praticien est responsable de la qualité de l'eau qu'il distribue à ses patients. Pour contrôler les risques d'infection, quelques méthodes simples d'amélioration de La qualité de L'eau sont proposées. Une étude est réalisée dans le but d'évaluer le niveau de connaissance et de prise de conscience des professionnels quand au rôle de l'eau comme facteur de contamination au cabinet dentaire.

Book excerpt: SCIENCE AND EMPIRES: FROM THE INTERNATIONAL COLLOQUIUM TO THE BOOK Patrick PETITJEAN, Catherine JAMI and Anne Marie MOULIN The International Colloquium "Science and Empires - Historical Studies about Scientific De velopment and European Expansion" is the product of an International Colloquium, "Sciences and Empires - A Comparative History of Scien tific Exchanges: European Expansion and Scientific Development in Asian, African, American and Oceanian Countries". Organized by the REHSEIS group (Research on Epistemology and History of Exact Sciences and Scientific Institutions) of CNRS (National Center for Scientific Research), the colloquium was held from 3 to 6 April 1990 in the UNESCO building in Paris. This colloquium was an idea of Professor Roshdi Rashed who initiated this field of studies in France some years ago, and proposed "Sciences and Empires" as one of the main research programmes for the The project to organize such a colloquium was a bit REHSEIS group. of a gamble. Its subject, reflected in the title "Sciences and Empires", is not a currently-accepted sub-discipline of the history of science; rather, it refers to a set of questions which found autonomy only recently. The terminology was strongly debated by the participants and, as is frequently suggested in this book, awaits fuller clarification.
Download or read book The Human Rights to Water and Sanitation written by Léo Heller and published by Cambridge University Press. This book was released on 2022-05-12 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: This analysis of the human rights to safe drinking water and sanitation (HRtWS) uncovers why some groups around the world are still excluded from these rights. Léo Heller, former United Nations Special Rapporteur on the human rights to water and sanitation, draws on his own research in nine countries and reviews the theoretical, legal, and political issues involved. The first part presents the origins of the HRtWS, their legal and normative meanings and the debates surrounding them. Part II discusses the drivers, mainly external to the water and sanitation sector, that shape public policies and explain why individuals and groups are included in or excluded from access to services. In Part III, public policies guided by the realization of HRtWS are addressed. Part IV highlights populations and spheres of living that have been particularly neglected in efforts to promote access to services.
Download or read book The Chemical Industry in Europe 1850 1914 written by Ernst Homburg and published by Springer Science & Business Media. This book was released on 1998-10-31 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Europe is the cradle of the modem international chemical industry. From the middle of the nineteenth century until the outbreak of World War I, the European chemical industry influenced not only the production and control of science and technology, but also made significant contributions towards economic development, as well as bringing about profound changes in working and living enviromnents. It is a highly complex heritage, both rich and threatening, that calls for close scrutinity. Fortunately, a unique opportunity to explore the historical development of the European chemical industry from a variety of novel standpoints, was made possible during 1993 as part of the European Science Foundation (ESF) programme called 'The Evolution of Chemistry in Europe, 1789-1939.' This process of exploration has taken place through three workshops, each dealing with different time periods. The workshop concerned with the period 1850-1914, which corresponds roughly to the so-called Second Industrial Revolution, was held in Maastricht, The Netherlands, on 23-25 March 1995. This volume is the outcome of that workshop. The other workshops dealing with European chemical industry were held in Liege in 1994, covering the First Industrial Revolution period, 1789-1850, and Strasbourg in 1996, covering the period between the two World Wars.
Download or read book Skin Microbiology written by H.I. Maibach and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Not since the 1965 pUblication of Skin Bacteria lind Their Role in Infection has our knowledge of clinical skin microbiology been reviewed and sum marized. In the more than a decade and a half since that publication, we have seen a careful reevaluation of the ideas and information current in 1965 and the development of important new discoveries and information. This volume, Skin Microbiology: Relevance to Clinical Infection, reviews developments in the field since 1965 and summarizes the current state ofthe art in thirty-six carefully prepared chapters. Emphasis is on the clinical per spective rather than straight microbiology, although we include enough of the latter to put the clinical aspects in a proper scientific context. The authors contributing to this volume represent a cross section of authorities in the many specialty areas that contribute to our knowledge of skin microbiology. They include investigators in microbiology, infectious disease, epidemiology, surgery, pediatrics, and dermatology. Significant ef forts have been made to minimize repetition and overlap in the various chapters. In some cases, however, information is deliberately repeated in order to provide for the reader a necessary frame of reference. We hope that this volume will be of value to dermatologists, microbio logists, pediatricians, surgeons, public health workers, nurses, and others in volved in the diagnosis and treatment of dermatologic problems caused by bacteria. The editors acknowledge with appreciation the assistance of Drs. A. Allen, F. Marzulli, F. Engley, G. Hildick-Smith, A. Kligman, M. Bruch, H. Eiermann, and D. Taplin.
Download or read book Arsenic in Drinking Water written by National Research Council and published by National Academies Press. This book was released on 2001-11-26 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.
Download or read book Agroclimatology written by Jerry L. Hatfield and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: Can we unlock resilience to climate stress by better understanding linkages between the environment and biological systems? Agroclimatology allows us to explore how different processes determine plant response to climate and how climate drives the distribution of crops and their productivity. Editors Jerry L. Hatfield, Mannava V.K. Sivakumar, and John H. Prueger have taken a comprehensive view of agroclimatology to assist and challenge researchers in this important area of study. Major themes include: principles of energy exchange and climatology, understanding climate change and agriculture, linkages of specific biological systems to climatology, the context of pests and diseases, methods of agroclimatology, and the application of agroclimatic principles to problem-solving in agriculture.
