In coming issues, The Rheumatologist will increase its coverage of drug safety. The goal of these articles will be to present emerging information on the crucial issues of risks and benefits of drugs currently in use. We want to inform and alert you about data to allow you and your patients to make the best decisions in the face of what will always be uncertainty.

Dr. Pisetsky is physician editor of The Rheumatologist and professor of medicine and immunology at Duke University Medical Center in Durham, N.C.
