Les professionnels impliqués dans la prescription ou la vente de lentilles de contact (ou lentilles cornéennes) constatent, au quotidien, en fonction du type de lentilles choisies et de leur entretien, que le port de lentilles cornéennes peut entraîner des sensations d'inconfort ainsi que des atteintes de la santé oculaire, parfois bénins, parfois plus sérieux. Quelle est la meilleure solution d'entretien pour améliorer l'expérience du porteur de lentilles de contact ? Quel mode de port doit-on privilégier ? Quelles sont les meilleures pratiques pouvant assurer une plus grande sécurité ? Quels sont les facteurs importants à considérer pour éviter le développement d'infection ou d'inflammation à la suite du port de lentilles ? Qui est à risque ? Ce sont ces thèmes que développe l'ouvrage Les lentilles de contact. Optimisation de l'adaptation, utilisation et entretien. Après une présentation de l'évolution des matériaux composant les lentilles, l'auteur présente les solutions d'entretien et de conservation des lentilles de contact avec leurs différents agents, et leur mode d'utilisation. La présence de lentilles de contact sur l'œil n'est pas anodine et tous les professionnels ou prescripteurs délivrant des produits et des lentilles de contact doivent veiller à réduire les risques d'infection au maximum. Si toutefois des complications surviennent, l'auteur propose une conduite à suivre. Ce livre expose les recommandations et les gestes au quotidien que le porteur de lentilles doit respecter : de la pose de la lentille à son retrait, son entretien, sa conservation pour la nuit. Les lentilles de contact. Optimisation de l'adaptation, utilisation et entretien s'adresse à tous les professionnels de la vision (ophtalmologistes, opticiens, étudiants en optométrie, orthoptistes, enseignants…) ainsi qu'aux porteurs de lentilles désireux de conseils pratiques dans le choix et l'entretien des lentilles de contact.

L’aventure spatiale a imposé une connaissance approfondie des mécanismes d’interface entre l’homme et un environnement hostile. Elle a mis en évidence la complexité du système visuel, son intégration avec les autres sens et la place essentielle des facteurs que sont l’attention, la cognition et la représentation mentale. La vision est donc apparue non seulement comme une fonction dédiée à un organe particulier, mais surtout comme une des fonctions nécessaires à la survie d’un organisme entier. Fruit d’une approche pluridisciplinaire, Avancées en ophtalmologie – Apport de la conquête spatiale montre comment la recherche en neurosciences liée aux vols spatiaux habités a permis des progrès remarquables dans le domaine des spécialités de la vision. Cet ouvrage relate également une aventure médicale et précise les bases physio-pathogéniques qui ont contribué à la structuration médicalisée du concept de malvoyance, puis à sa prise en charge et à son enseignement. Il s’adresse non seulement à l’ensemble des professionnels de la vision, mais aussi aux ergothérapeutes, psychomotriciens, instructeurs en locomotion, psychologues, gériatres, chercheurs, médecins généralistes, etc...

It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Most women who die from cervical cancer, particularly in developing countries, are in the prime of their life. They may be raising children, caring for their family, and contributing to the social and economic life of their town or village. Their death is both a personal tragedy, and a sad and unnecessary loss to their family and their community. Unnecessary, because there is compelling evidence, as this Guide makes clear, that cervical cancer is one of the most preventable and treatable forms of cancer, as long as it is detected early and managed effectively. Unfortunately, the majority of women in developing countries still do not have access to cervical cancer prevention programmes. The consequence is that, often, cervical cancer is not detected until it is too late to be cured. An urgent effort is required if this situation is to be corrected. This Guide is intended to help those responsible for providing services aimed at reducing the burden posed by cervical cancer for women, communities and health systems. It focuses on the knowledge and skills needed by health care providers, at different levels of care.

This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.

These guidelines have been developed to support countries to relieve pain in their paediatric populations. These guidelines address persisting pain in children caused by conditions such as cancer, HIV/AIDS, sickle-cell disease, burns, trauma, and phantom limb pain. Recommendations -- developed following a careful and transparent appraisal of available evidence -- are presented for the pharmacological treatment of mild, moderate and severe pain. The guidelines include chapters on the various systems used to classify pain and on the evaluation of pain, which reviews the available tools for routine pain measurement in children. Provision of sustainable pain relief within health care systems is covered in a separate chapter. Since morphine and other opioid analgesics -- required for the relief of moderate-to-severe pain in children -- are listed under the 1961 UN Single Convention on Narcotic Drugs, the new guidelines include an annex explaining the Convention's requirements for the handling and procurement of opioid analgesics for the relief of pain.
