Medicine turns to the lowly maggot
'They're definitely our friends at this house'

LOS ANGELES (CNN) -- Despite the availability of modern
antibiotics and the latest in surgical procedures, people
with poor circulation suffer from injuries that heal slowly
or not at all.
But a California researcher has found a treatment that may
not be for the squeamish, but it works: He's using maggots to
clean out wounds and accelerate healing.
Dr. Donald Sherman of the University of California in Irvine
uses maggots, or fly larvae, which were first discovered to
be beneficial centuries ago.
Sherman says military doctors found that "wounded soldiers on
the battlefield whose wounds became infested with maggots did
much better" than those not visited by maggots.
Sherman has used hundreds of sterile larvae from green
blowflies to help people like Vitus Smieja, who nearly lost
his legs in 1995 when several infections wouldn't heal.
"They were just getting worse and worse," Smieja says. "And
when they said they may amputate, it just about knocked me
out."
'They're definitely our friends at this house'
Sherman says the maggots dissolve dead and infected material,
yet leave healthy tissue alone. They also secrete enzymes
that kill bacteria.
"We've been able to show that wounds not healing or even
enlarging have actually reversed that pattern and start
healing at a rate several-fold faster," Sherman says.
"The first time that I saw his legs after they took the
maggots off it just looked better," says Smieja's wife, Ella.
"It just looked good!"
Smieja's infection after several weeks of treatment
"It was heartwarming to see that happen," says Smieja,
"because I didn't want to lose these legs."
Not every patient is a candidate for this kind of therapy.
But for diabetics and others with poor circulation whose
wounds won't heal, a few visits from the maggots may be the
difference between healing and amputation.
"They're definitely our friends at this house," says Ella
Smieja.
