WASHINGTON - Researchers have found high
concentrations of platinum in women who got silicone breast implants and in
the children they bore and breast-fed afterward.
The type of platinum found in the women's blood and
urine was different than the traces of regular platinum not uncommon in
people's bodies. It was a highly reactive platinum, used to help turn
silicon oil into the honey-like gel that lends a more natural feel to a
breast implant.
Concentrations were up to three times higher than
in women who didn't have breast implants, according to findings by S.V.M.
Maharaj, a chemist at American University. Maharaj was scheduled present the
findings Thursday to the American Chemical Society in Philadelphia.
Ernest Lykissa, a forensic and clinical
toxicologist who co-authored the paper, said the study's sample size was
small. But Lykissa said it fairly represented hundreds of women with
implants he's studied over the years.
Women who had implants the longest recorded the
highest platinum concentrations. The heavy metal was also found in bone
marrow, where blood cells are made.
Distinct from platinum released by catalytic
converters in cars, platinum in implants is treated with nitric and
hydrochloric acids and becomes very reactive, Lykissa said. The heavy metal
readily binds in the human body, especially to nerve endings,
short-circuiting communication with the brain.
"You see green, but you perceive a full moon," he
said. "All of a sudden, your brain system is not working right."
Some women developed nervous tics, had faulty
perception, and impaired hearing and eyesight, he said.
Children born to women with implants had problems
with eyesight and hearing, too, but those nervous system disorders may have
been caused by something else, he cautioned.
The Food and Drug Administration in January stunned
plastic surgeons when, contradicting the advice of its expert panel, it
rejected Inamed's bid to reintroduce silicone breast implants. After safety
concerns rose, the FDA banned such implants in 1992 for most patients.
In January, the drug regulatory agency asked Inamed
for more details about what happens when silicone seeps from the implant.
Dan Cohen, a spokesman for Santa Barbara,
Calif.-based Inamed, said the company would speak in detail about its formal
reply, submitted to the FDA earlier this month.
But at the FDA's October 2003 advisory board
meeting, the company briefly discussed platinum dispersion and concentration
in implant patients. The company has tracked those patients for three years.
"It was not an issue that anyone dwelled on _
either our presentation or the panel," Cohen said.
For its part, the FDA in 2002 surveyed scientific
literature that indicated platinum leaks from implants into surrounding
breast tissue. Researchers said they didn't find anything suggesting women
had allergic responses to leached platinum.
Paul H. Wooley, director of research for orthopedic
surgery at Wayne State University, said it's been suspected for at least a
decade that heavy metals used in manufacturing might cause problems for
women who receive implants.
"I'm not sure these questions have been answered
because, in general, they haven't been asked," Wooley said. "For political
reasons, working on breast-implant patients has been somewhat difficult to
do."
