And the winner is . . . CMAJ 2000;162:1342 CMAJ's second OSLER Challenge has been won by Dr. Henry Phillips of Kingston, Ont. OSLER (the CMA's free online search service) users were asked to submit the MEDLINE searching strategy that they used to answer this question: Is there any evidence that zinc lozenges shorten the duration and severity of the common cold in children? A copy of Jacalyn Duffin's History of Medicine: a Scandalously Short Introduction, goes to Phillips. Details of the strategy needed to conduct the search and various searching techniques will be reviewed in a future On the Net column. Physicians interested in using OSLER can contact Member Services, 800 457-4205.
