...children with such horrific structural defects, the only solution is extensive and grueling surgery. Doctors take bone from the patient's own body, usually from the ribs or hips, and graft it to the existing bone in the head and face. Unfortunately, the patient has a limited amount of spare bone, the "harvesting" process can mean additional trauma, and frequently the transplanted material is absorbed back into the body before new bone has formed. But now doctors may have a way of overcoming these difficulties. Last week Boston researchers announced that they had made successful repairs in more than...
...bizarre outpouring reminded some observers of the more hysterical manifestations of the Cultural Revolution in China in the 1960s. In reality it was the latest national morality campaign promulgated by South Korean President Chun Doo Hwan, the former general turned strongman who has been zealous about rooting out graft and creating what he calls a "clean and honest climate" in the country.

So these patients have the same kind of sensations as with a skin graft. It isn't perfect, but it is very good." The artificial dermis breaks down as new natural tissue forms. The plastic top layer acts solely as a temporary protective covering; beginning as early as ten days after the artificial skin graft, postage-stamp size patches of plastic are peeled...
