TAILIEUCHUNG - ATSDR Case Studies in Environmental Medicine

Diagnostic nuclear medicine began more than 50 years ago and has evolved into a major medical specialty. Its practitioners use low activity levels of radioactive materials in a safe way to gain information about health and disease. Small amounts of radioactive materials, known as radiopharmaceuticals, are intro- duced into the body by injection, swallowing, or inhalation. Different radiopharmaceuticals are used to study different parts of the body. These agents emit photons that can be detected externally by special cameras. These cameras produce images on film and/ or work in conjunction with computers to produce images of the body’s organs. An estimated 12–14 million nuclear medicine procedures are performed each year in the United States | ATSDR Case Studies in Environmental Medicine Arsenic Toxicity Atsdr AGENCY FOR TOXIC SUBSTANCES AND DISEASE REGISTRY CS213O21-A AGENCY FOR TOXIC SUBSTANCES AND DISEASE REGISTRY CASE STUDIES IN ENVIRONMENTAL MEDICINE Course WBCBDV1576 Date October 1 2009 Expiration Date October 1 2011 ARSENIC TOXICITY Key Concepts Prolonged arsenic exposure causes skin and lung cancer and may cause other internal cancers as well. Skin lesions peripheral neuropathy and anemia are hallmarks of chronic arsenic exposure. About This and Other Case Studies in Environmental Medicine This educational case study document is one in a series of self-instructional modules designed to increase the primary care provider s knowledge of hazardous substances in the environment and to promote the adoption of medical practices that aid in the evaluation and care of potentially exposed patients.
