Morphine kills pain -- not patientsA number of people, including health care workers, think that morphine is a lethal drug that causes death when used to control pain for a patient who is dying. That is a misconception as per new research reported in the latest issue of Palliative Medicine, from SAGE Publications.

Root Beer May Be "Safest" Soft Drink for TeethExposing teeth to soft drinks, even for a short period of time, causes dental erosion-and prolonged exposure can lead to significant enamel loss. Root beer products, however, are non-carbonated and do not contain the acids that harm teeth, as per a research studyin the March/April 2007 issue of General Dentistry, the AGD's clinical, peer-evaluated journal.
