Arthritis has various forms, including rheumatoid and osteoarthritis. But it can be helped. That's the topic of Saturday's Deseret Morning News/Intermountain Healthcare Hotline. From 10 a.m. to noon, Dr. Don Stromquist and Dr. Sean McMillan, both rheumatologists at LDS Hospital, will take phoned-in questions. All calls are confidential. From the Salt Lake area, call 236-6061. Elsewhere, the toll-free number is 1-800-925-8177 but the numbers are operational only during the hotline hours.
