Book excerpt: Since the publication of the first edition of Radiotherapy of Intraocular and Orbital Tumors in 1993 the treatment programs for cure have changed from the dominance of surgical resection to the utilization of radiation therapy with preservation of the eye intact and preservation of vision. In 2002 about 2,300 primary eye tumors will be diagnosed in the United states, 75% of which will be choroidal melanomas, 20% retinoblastomas, and the remainder a wide variety of tumors - malignant lymphoma, rhabdomyosarcomas, liposarcomas, meningiomas, malignant fibrous histiocytomas, etc. Even so, the majority of malignant tumors of the eye are metastatic, primarily from cancers of the lung or breast. The impact of newer imaging studies, including computed tomography, magnetic resonance imaging, and ultrasound with and without contrast medium, have allowed for better tumor definition, more precise treatment techniques, and major improvement in local control, with preservation of the eye intact and excellent survival. The better histologic definition of the tumor has selected more appropriately the cases suitable for adjuvant chemotherapy particularly demonstrated by the combined integrated multimodal treatment of rhabdomyosarcoma without enucleation. Surgical techniques are now being reserved for biopsy and for treatment failures, a dramatic change in treatment approaches since 1993. The second edition by Sagerman and Alberti clearly demonstrates this major change in treatment. The volume explores the impact of diagnostic workup, the role of surgery, the role of external beam radiation therapy, the use of radioactive plaques, photocoagulation, cryotherapy, and other less major surgical procedures.

This book was released on 1990-02-01 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reevaluates the health risks of ionizing radiation in light of data that have become available since the 1980 report on this subject was published. The data include new, much more reliable dose estimates for the A-bomb survivors, the results of an additional 14 years of follow-up of the survivors for cancer mortality, recent results of follow-up studies of persons irradiated for medical purposes, and results of relevant experiments with laboratory animals and cultured cells. It analyzes the data in terms of risk estimates for specific organs in relation to dose and time after exposure, and compares radiation effects between Japanese and Western populations.

Book excerpt: The spectral transmittance of ultraviolet, visible, and near infrared light through the ocular media of humans has been measured. Using freshly enucleated eyes, the transmittances of each component part (cornea, aqueous humor, lens, vitreous humor) were determined for the wavelength range from 0.22 to 2.8 microns. To date 9 eyes have been measured, ranging in age from 4 weeks to 75 years. Two types of measurements were made: the first to measure the total light transmitted (direct and scattered) at each wavelength and the second to measure the percent transmittance of that light passing directly through the various media without absorption or scattering. The results show that: (a) the transmission of ultraviolet radiation decreases with the age of the eye; (b) the transmission of infrared radiation appears to be independent of the age; and (c) the maximum total transmittance of the whole eye, about 81 percent, is obtained in the region from 600 to 850 millimicrons.

This book was released on 2017-01-15 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the lectures presented at the International School of Radiation Damage and Protection at the "Ettore Majorana" Centre for Sci entific Culture in Erice, Italy, September 6-15, 1985. The sixth course of the School, entitled "Advances in Applications, Biological Effects, and Dosimetry of Ultrasound," provided an in-depth review of all facets of ultra sound interactions and their biological effects on living systems, allowing an assessment of the hazard potential of the various applications of ultra sound. Particular reference was made to possible health risks associated with medical ultrasound exposure since this use is by far the most prevalent. Since the initial application of ultrasound to submarine detection, medical diagnostic and therapeutic applications have become predominant over the past 20 years. The question of safety of this physical agent is an extremely important one. In many industrialized countries most pregnant women receive at least one diagnostic ultrasound examination before the birth of the child. Thus, potential hazards to the fetus are of prime concern. This problem has been aggravated by the fact that the medical diagnostic applications of ultrasound have far outpaced research efforts on biological effects. A further compounding factor of concern to clinicians and scientists has been the use of higher and higher intensities by the manufacturers of ultrasound equipment, particularly higher peak pulse intensities.

Book excerpt: Widely regarded as the cornerstone text in the field, the successful series of editions continues to follow the tradition of a clear and comprehensive presentation of the physical principles and operational aspects of medical imaging. The Essential Physics of Medical Imaging, 4th Edition, is a coherent and thorough compendium of the fundamental principles of the physics, radiation protection, and radiation biology that underlie the practice and profession of medical imaging. Distinguished scientists and educators from the University of California, Davis, provide up-to-date, readable information on the production, characteristics, and interactions of non-ionizing and ionizing radiation, magnetic fields and ultrasound used in medical imaging and the imaging modalities in which they are used, including radiography, mammography, fluoroscopy, computed tomography, magnetic resonance, ultrasound, and nuclear medicine. This vibrant, full-color text is enhanced by more than 1,000 images, charts, and graphs, including hundreds of new illustrations. This text is a must-have resource for medical imaging professionals, radiology residents who are preparing for Core Exams, and teachers and students in medical physics and biomedical engineering.

Book excerpt: The 2001 report completed a comprehensive review of the risks to offspring following parental exposure to radiation. The review included an evaluation of those diseases which have both hereditary and environmental components. The major finding is that the total hereditary risk to the first generation following radiation is less than one tenth of the risk of fatal carcinogenesis following irrradiation. The Committee concluded that a sounder basis now exists for estimating the hereditary risks of radiation exposure. This is due to advances in molecular genetics, and in the evaluation of multifactorial diseases, such as coronary heart disease.
