Radiologists uncover and label a new teen affliction
Researchers evaluating a new technique for locating and removing objects accidentally embedded in the body say they may have uncovered a new form of self-mutilating behavior in which teenagers intentionally insert objects into their flesh.

Personnel at Nationwide Children's Hospital in Columbus, Ohio, report extracting 52 foreign objects that 10 teenage girls deliberately embedded in their arms, hands, feet, ankles and necks over the last three years, including needles, staples, wood, stone, glass, pencil lead and a crayon.

One patient had inserted 11 objects, including an unfolded metal paper clip more than 6 inches long.
