<p>When 10-year-old Charlie Cagann went to Lurie Children's Hospital in Chicago to have his adenoid removed, he was nervous about the surgery. But when he arrived at the hospital, there was something to help take his mind off things: an iPad.</p><p>Charlie who already owns an iPhone touch picked up the Apple tablet and started playing one of his favorite games, Subway Surfers. Soon, he was completely at ease.</p><p>"It was fun to use it," he remembers. "It makes you focus on the iPad, and it takes your mind off the surgery."</p><p>The iPad already has won the hearts of doctors across the country, and now, they've started experimenting with the popular tablet computer as an anxiety reducer for children. Doctors at the University of Chicago use an app that recreates the in-utero sound of the human heart to distract newborns as they're undergoing spinal taps. Doctors use another app, called Free Candle, in which the point is to blow out a candle, to get sick kids to really blow hard when checking their lungs. Over at Lurie, where Charlie had surgery two weeks ago, kids can chose everything from Fruit Ninja to Angry Birds to ease anxiety.</p><p><a href="http://www.wired.com/wiredenterprise/2013/06/hospital_ipad/">Keep reading...</a></p>
