In this April 15 file photo, 17-year-old Sydney Corcoran is tended to at the finish line of the Boston Marathon after two bombs exploded within seconds of each other. More than 180 people were hurt in the explosions, and at least 14 of them lost all or part of a limb. But one week after the Boston Marathon bombings, doctors say everyone injured in the blasts who made it alive to a hospital now seems likely to survive. (AP Photo/Boston Globe photo: John Tlumacki)
