To the Editor:— A study is being made in the Department of Pharmacology and Toxicology of the University of Rochester School of Medicine and Dentistry, under the direction of Dr. Harold Hodge, to determine to what extent the effects of therapeutic drugs and exposure to toxic chemicals contribute to the high death and disability rates due to accidents. This study is part of a wider consideration of the medical aspects of accident control, and is concerned particularly with the problem of injuries and poisonings which occur in homes and on farms. There is special emphasis on the etiology of accidents to children between the ages of 1 and 20 years, since accidents are the leading cause of death in this age group, and second only to congenital malformations as a cause of permanent disability. In dealing with industrial and traffic accidents some degree of mechanical and legal control is possible.
