I carefully reviewed these trials, allowing development of recommendations for use of LMWH in clinical practice. A large amount of data is available for evaluating the use of LMWH in treatment of venous thromboembolism and in prophylaxis against venous thromboembolism. Less data are available concerning the utility of these agents in cardiovascular and cerebrovascular disorders. These agents are also excellent pharmacologic prophylactic agents in orthopedic surgery patients.
Recent data suggest use in unstable angina in place of heparin.
Other indications for use are not as well defined at this time. Technologic advances have led to increased use of computers at home and in the workplace. It is estimated that more than 100 million workers in the United States and Canada will be using computers daily by the year 2000. We reviewed pertinent articles in the literature. Several studies have addressed the role of VDTs in disease causation, specifically whether EMR causes skin or ocular disease or obstetric complications.
