The atlas offers a comprehensive and up-to-date overview of frontal sinus surgery. In recent years there have been great advances in endoscopic nasosinusal surgery but they have been particularly prominent in frontal sinus surgery. The book provides complete instructions for a gradual learning of the different surgical techniques and includes surgical pearls. It is enriched with videos presenting real-time guidance for frontal sinus endoscopic procedures. The book will meet the needs of both trainees and more experienced practitioners, and will enable them to make steady progress in endoscopic surgery and to adopt a more complete and safe approach to the frontal sinus. It will be of interest also for ophthalmologists, maxillofacial surgeons and neurosurgeons.
Features, Transmission, Detection, and Case Studies in COVID-19 examines the effects of the virus on the body, as well as its transmission and clinical profile. This volume begins with an introduction to the virus and its pathogenesis, transmission, and avoidance, followed by sections on pulmonary and cardiovascular effects, obesity, diabetes, the liver, detection issues, and biomarkers. Vaccines and treatment are also discussed. Specific case studies covered include hypoxia, acute kidney injury, pneumonia, and neurological effects. This volume is relevant for all clinicians and scientists working to ensure the best outcomes for patients with COVID-19. - Discusses COVID-19 biology, including...
A growing body of evidence from economic studies shows areas where appropriate policies can generate health and other benefits at an affordable cost, sometimes reducing health expenditure and helping to redress health inequalities at the same time.
The volcanic and oceanic nature of the Canary Islands, its rich plant biodiversity and high rate of endemism, as well as the relict character of some of its plant communities make it a territory of great biological interest. The main geographic, climatic, bioclimatic, biogeographic and floristic features of the Islands are shown and related to the distributional pattern of potential communities along an altitudinal gradient. Current vegetation units and their ecology are described and illustrated with numerous pictures. Potential vegetation units are summarized and comprehensive maps of the potential natural vegetation for each island are given. Human impact on the natural landscape, the occurrence of invasive plants, and the probable impact of climate change on the flora and vegetation are discussed. The conservation status of flora and vegetation are assessed. Four appendixes include a syntaxonomical scheme, a brief history of botanical studies and explorations in the Islands, ethnobotanical notes, and a list of selected literature.
Because procedures are not in place in many schools and school districts to successfully determine academic placement of English language learners, many of these learners are placed inappropriately. Some who don't need special services (other than English as a second language) may find themselves in special education classes. Others who need special services may be placed in regular classes without the extra supports and services that they need. Working with English language learners and with students requiring special education services requires collaboration among teachers, school psychologists, speech pathologists, and assessment personnel with expertise in general, bilingual, and special education.
