Maggots: Not Just for Your Tea Anymore

(props to my co-worker, Kevin G., for that headline)

Maggots are making a medical comeback, cleaning out wounds that just won't heal (CNN - AP - 3 Aug 2004)

It's a therapy quietly championed since the early 1990s by a California physician who's earned the nickname Dr. Maggot. But Dr. Ronald Sherman's maggots are getting more attention since, in January, they became the first live animals to win Food and Drug Administration approval -- as a medical device to clean out wounds. ...

His research shows that in the mere two to three days they live in a wound, maggots also produce substances that kill bacteria and stimulate growth of healthy tissue. ...

This has been quite a year for wormlike critters. In June, FDA also gave its seal of approval to leeches, those bloodsuckers that help plastic surgeons save severed body parts by removing pooled blood and restoring circulation. And in the spring, University of Iowa researchers reported early evidence that drinking whipworm eggs, which causes a temporary, harmless infection, might soothe inflammatory bowel disease by diverting the overactive immune reaction that causes it. ...

Drop maggots into the wound and cover with a special mesh to keep them in place. Two to three days later, after the maggots have eaten their fill, lift them off and dispose. ...

Patients say it's not that hard to accept. Pamela Mitchell of Akron, Ohio, begged to try maggots when surgeons wanted to amputate her left foot, where infection in an inch deep, 2-inch-wide diabetic ulcer had penetrated the bone. It took 10 cycles of larvae, but she healed completely.

How did they feel? On day 2, when the maggots were fat, "I could feel them moving, because they were ready to come out," she recalls. But, "if you're faced with amputation or the maggots, I think most people would try the maggots."
