Although nosocomial, or hospital-acquired, infections have been well cataloged and are fairly well understood, traditional solutions have failed to completely eliminate the problem. Even the most modern hospitals find themselves stymied by the persistence of these pathogens in hospital wards and operating rooms. The degree to which most of these infections are airborne is not known, but a growing body of evidence indicates that airborne transmission plays a role in many hospital-acquired infections. Addressing one of the most important topics in health care, Hospital Airborne Infection Control is the first book to deal with the control of airborne nosocomial infections in detail. It identifies all pathogens known or suspected to be airborne, along with their sources in hospital environments. It also summarizes all epidemiological evidence for airborne transmission. The text addresses respiratory, surgical site, burn wound, immunocompromised, pediatric, nursing home, and non-respiratory infections. In each category, an extensive number of examples show that inhalation is not the only airborne route by which infections may be transmitted. Noting that airborne transmission and surface contamination are virtually inseparable, the author emphasizes that both air and surface disinfection, including hand hygiene, are important factors in controlling the transmission of airborne disease. He also proposes a variety of new solutions and technologies, including ultraviolet, ionization, ozone, plasma, and vegetative air cleaning systems. A compendium of scientific and medical information, this book helps hospitals control nosocomial infections and outbreaks spread by the airborne route as well as by direct contact and contact with fomites or contaminated equipment.

This book provides comprehensive coverage of corneal collagen cross-linking (CXL), a major management modality for keratoconus and ectatic corneal disorders. All aspects are covered, including refractive and non-refractive surgery indications, models of application, safety, efficacy, performance, outcome measures, evidence of CXL, complications, contraindications, use in children, and controversies. The discussion reflects the considerable progress that has been made in understanding of the modality since its development in the late 1990s. Detailed attention is paid to new concepts, changing surgical techniques and indications, the latest evidence-based science and research, and the future of CXL. Guidance is also provided on the use of CXL in combination with other modalities, such as LASIK, PRK, intracorneal ring implantation and others. The text is accompanied by numerous high-quality color illustrations. Corneal Collagen Cross Linking will provide the reader with a sound grasp of the technique and its use and will hopefully also serve as a stimulus to further research and advances.
