"The Treatment of Poisoning in Children" by Diane Aschenbrenner (Drug Watch, February) included an incorrect telephone number for national poison control. The correct number is (800) 222-1222.

"On the Campaign Trail" by Karen Roberts (Profiles, February) contained several errors. Marc Perez, CRNA, RN, is a member of the Franklin County, Missouri, Planning and Zoning Commission (not committee); he was appointed to the commission in 2003 (not 1993); and he has been a member of the Republican Party since 1994 (it could be inferred from the article that Perez made a recent switch from the Democratic to the Republican Party). We regret the errors.
