V. M. Maharaj (1) Department of Chemistry, American University, Washington, DC 20016, USA Received: 5 January 2004 Revised: 28 May 2004 Accepted: 7 June 2004 Published online: 8 July 2004 Abstract Inductively coupled plasma-mass spectrometry (ICP-MS) was used to determine the concentration of platinum (Pt) in silicone breast implant gel (range, 0.26?48.90 g g?1 Pt; n=15), elastomer (range, 3.05?28.78 g g?1 Pt; n=7), double lumen (range, 5.79?125.27 g g?1 Pt; n=7), foam (range, 5.79?8.36 g g?1 Pt; n=2), and capsular tissue (range, 0.003?0.272 g g?1 Pt; n=15). The results show that very high levels of Pt are present in the encasing elastomer, double lumen, and foam envelope materials. Silicone breast implants can be a source of significant Pt exposure for individuals with these implants.

The reactive platinum, unlike other inert platinum in the body, can cause various forms of neurological damage and asthma-like allergic reactions, said Ernest Lykissa, a Houston clinical toxicologist who co-authored the paper. Maharaj, a chemist at American University, detailed the findings to an American Chemical Society meeting in Philadelphia. Lykissa, who four years ago disclosed some of his preliminary research to the Star Tribune, said the paper presented Thursday reported sharply higher levels of reactive platinum in the blood and urine of 10 women who had implants than in five control subjects. While the sample size is small, he said in a phone interview, the results reflect those in similar tests he has since performed on hundreds of women. Lykissa said that his research also has been confirmed by a group of German scientists and that it offers an explanation for many of the illnesses alleged by hundreds of thousands of women who received silicone gel implants. Kathleen Quinn, a spokeswoman for the Food and Drug Administration (FDA), said the agency " is not able to comment ... at this time " on the paper. The FDA declined last winter to lift a 12-year-old moratorium and allow Santa Barbara, Calif.-based INAMED Corp. to put silicone breast implants back on the U.S. market. INAMED grew from a former subsidiary of Maplewood-based 3M, which got out of the breast implant business in 1984 and has paid more than $1 billion to settle suits over its products. Dan Cohen, INAMED's vice president for global government affairs, said he would not " dismiss [the new study] until I've had the chance to have our scientists review it. " But, he said, the company has seen " no peer-reviewed, credible data that would support Mr. Lykissa's claim. " Cohen said the FDA's letter rejecting INAMED's petition to fully market its silicone breast implants included " no discussion of the platinum issue. " Page 53 A catalyst INAMED and the California-based Mentor Corp. continue to sell silicone gel implants for use in reconstructive surgery for breast cancer victims or for women volunteering for clinical studies. Silicone implant makers have used platinum for decades to produce a catalyst. The catalyst causes silicone oil to thicken into a gel. At issue is whether platinum left over from those reactions is inert or reactive and whether it leaks into women's bloodstreams if the implants rupture. Some government scientists have expressed concern that not all of the platinum from the manufacturing process would be neutralized. Lykissa said reactive platinum " is notorious for attacking nerve endings and interfering with the nerve impulses to the brain. " Women he has examined, he said, suffer from pain in their fingers and toes, have ticks in their eyes, memory lapses and equilibrium or eyesight imbalances. " The children that we tested that I have seen have all suffered from hearing and eye problems " after being breast fed. " There were platinums detected in the breast milk of those mothers,' " Lykissa said. Greg Gordon is at ggordon@....

Determination of siloxanes, silicon, and platinum in tissues of women with silicone gel-filled implants. Flassbeck D, Pfleiderer B, Klemens P, Heumann KG, Eltze E, Hirner AV. Institute of Environmental Analytical Chemistry, University of Essen, Germany. Silicone [poly(dimethylsiloxane)] gel used in breast implants has been known to migrate through intact silicone elastomer shells, resulting in the clinically observable " gel bleed " on the implant surface. Although silicon concentrations in capsular tissues of women with silicone prostheses have been measured with element-specific silicon analyses, no silicone-specific investigation of these tissues has been performed as yet.A combination of element-specific inductively coupled plasma high-resolution isotope dilution mass spectrometry (ICP-HR-IDMS) and species-specific gas chromatography coupled mass spectrometry (GC-MS) was used to analyze silicon, platinum, and siloxanes in prosthesis capsule, muscle, and fat tissues of women (n=3) who had silicone gel-filled breast implants and in breast tissue of non-augmented women (n=3) as controls.In all tissues of augmented women, siloxanes, in particular octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcyclohexasiloxane (D6) were identified. Depending on the siloxane species and type of tissue analyzed, siloxane levels in the range of about 10-1,400 ng g(-1) were detected; total silicon was found in all tissue samples in the range of about 8,900-85,000 ng g(-1). Higher platinum levels ranging from 25-90 ng g(-1 )were detected in fibrin layer and fat tissue of two patients with prostheses. No siloxanes were detected in control breast tissue samples.This investigation of human tissues by a combination of element-specific and species-specific analytical techniques clearly demonstrates for the first time that platinum and siloxanes leak from prostheses and accumulate in their surrounding tissues.

Download to Citation Manager PubMed Citation Related Articles in PubMed CASE REPORT. The authors present a case of a patient with an abdominal CSF pseudocyst that resulted from an allergic reaction to silicone. The patient underwent repair surgery of the meningomyelocele associated with the Chiari II malformation, and the V-P shunt was instituted at 6 months of age. A formation of the abdominal CSF pseudocyst and the consequent shunt malfunction were observed 40 days after the V-P shunt. An increase in the number of the peripheral eosinophils and serum immunoglobulin E (IgE), and an infiltration of eosinophils in the specimen harvested from the pseudocyst wall suggested an allergic reaction as the cause of the pseudocyst. A sixth operation to revise the V-P shunt was performed using the shunt system made of 'extracted silicone', which was produced extracting the allergic substances. OUTCOME. The serum IgE was normalized after surgery and the abdominal CSF pseudocyst has not recurred for 22 months.

Columbia University College of Physicians and Surgeons, New York, NY. 10032, P. Chander. New York Medical College, Vahalla, NY. 10595 Silicone breast implants have been reported to increase the risk for development of autoimmune disease in adults. We report the occurrence of systemic lupus erythematous in two children, a 15 year old boy in 1992, 12 years after a silicone testicular prosthesis was implanted In the scrotum for cosmetic reasons (unilateral cryptorchidism), and a 10 year old girl in 1981, two years after a silicone scleral sponge was implanted in her eye (retinal detachment). Both developed lupus nephritis requiring treatment with prednisone and azathioprine to control their disease. 2/50 children who have had renal biopsies for lupus nephritis at Babies Hospital between 1977-19933 have had silicone implants prior to their developing SLE. In addition, we have examined a silicone testicular implant electively removed from an asymptomatic 7 year old boy and demonstrated significant granular mural small vessel staining with anti-sera to IgM. mild staining with anti-IgG and minimal staining with anti-IgA, C1 and C3 in the fibromuscular tissue. These observations, although limited, suggest development of lupus in children in association with silicone implants at sites other than the breast.

Young VL, Hertl MC, Murray PR, Jensen J, Witt H, Schorr MW. Division of Plastic and Reconstructive Surgery, Washington University School of Medicine, St. Louis, Mo., USA. In vitro and in vivo experiments were conducted to determine whether intraluminal saline in breast implants can support the growth of common wound-infecting microorganisms over a prolonged period of time. The bacteria tested were Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Corynebacterium jeikeium, Enterobacter cloacae, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Three fungal species also were tested: Aspergillus fumigatus, Paecilomyces variotii, and Candida albicans. In the in vitro study, four organisms survived in flasks of sterile saline for the 2 weeks in which serial cultures were performed: K. pneumoniae, C. albicans, A. fumigatus, and P. variotii. In the in vivo study, 61 white rabbits (122 implants) received both an experimental implant inoculated with one of the test organisms and a control implant containing only sterile saline. They were sacrificed at 1-, 3-, or 6-month scheduled endpoints. None of the control implants containing sterile saline had positive cultures. In contrast, the intraluminal saline was culture positive for 7 of the 10 inoculated organisms after varying lengths of time: S. epidermidis, E. coli, E. cloacae, K. pneumoniae, P. aeruginosa, A. fumigatus, and P. variotii. Samples of capsular tissue also were cultured. Of the 122 capsular tissue specimens, 21 (17 percent) had positive cultures and surrounded both inoculated and sterile implants. In most instances, capsules that were culture positive contained an organism different from the one that had been inoculated in the group. In only 3 cases was the same organism cultured from both the periprosthetic tissue and the intraluminal saline, and these may represent instances of the inoculated organism migrating through the implants filler valves. The data show that several types of bacteria (particularly gram-negative species) and fungi can grow and reproduce in a restricted saline environment for extended periods of time.

(She improved after the removal of her legs and part of her hands) [Tell her how safe Saline implants are] It goes on to say In 1988, Nordstrom et al. mentioned a case of Serratia marcescens infection of a tissue expander (saline type of implant) used for postmastectomy breast reconstruction. As in our patient, bacteria were cultured from both the periprosthetic fluid and the SALINE WITHIN THE IMPLANT. The exact relationship between bacteria inoculation within or about an implant and the origin of the infection remains a mystery. The ability of bacteria to traverse the membrane elastomer appears to hold the key to understanding this pathologic process. The permeability of silicone (saline) implants to substances or organisms occurs by means of two proposed mechanisms. Either a substance can diffuse directly though the membrane elastomer (as with ether, lidocaine, iodine, steroids, and certain antibiotics) or it must leak though holes in the membrane or fill ports.

See The Lancet Infectious Diseases, February 2005, pages 94-106 However, infection complicates 2-2•5% of breast implantations, and is the leading cause of illness following such surgery. The comprehensive review in The Lancet Infectious Diseases of infection of breast implants is particularly timely in light of the recent call for tighter regulation of the private cosmetic surgery industry in the UK. Professor Brigitte Pittet (Plastic and Reconstructive Surgery Unit, University of Geneva Hospitals, Geneva, Switzerland) and colleagues provide a fascinating journey through the history of breast implants and review the myriad risk factors for breast implant infections, before discussing clinical features such as toxic shock syndrome and late infection occurring months - or even years - after implantation. Diagnostic and management strategies are proposed for such problems. In addition, they discuss the idea that capsular contraction - the leading long-term complication that follows breast implantation, involving the formation and contraction of a collagenous sheath around the implant, thus forming hard, spherical masses in the breasts - may be caused by subclinical infection, and could be prevented by antibiotics. Brigitte Pittet comments: “Patients should be aware that, similar to other invasive procedures involving the implantation of foreign material, breast implants may lead to potential complications such as infection or capsular contracture. In good hands, however, infection remains infrequent.” Contact: Professor Didier Pittet, Infection Control Programme, University of Geneva Hospitals, 24 Rue Micheli-du-Crest, 1211 Geneva 14, Switzerland.

I asked for the most recent data. That information is now available on the net by clicking o n the website Press hyperlinked. You then go to chart #3. So the sum total from the last report of 195,202 (including 123 deaths which were not reported here) is now 234,187 Adverse Reports! I added up the number for the last quarter 1999, all 2000+the first quarter 2001=36,089! 36,089 ADVERSE REPORTS TO THE FDA in the last two years! The grand total 234,187--AND THAT'S OK?

Subject: An internal memorandum that discloses the " Dow Strategy " for the Breast Implant Cover-Up Date: 2004-10-18 21:50:53 PST From anonymous sister - scanned but not corrected - possibly from the Catch files. This is an internal memorandum that discloses the " Dow Strategy " for the Breast Implant Cover-Up. June 24, 1991 It has been two weeks since we had the great session with the BOD at which time they pointed out some of the problems we were facing and suggested ways we might get beyond them. This communication is intended to simply summarize where I feel we are. The issue of " cover-up " is going well from a long-term perspective are moving rapidly ahead on our press conference, and all things appear to be in place for that with the exception of the University of Michigan study being finalized. I did talk to four other presidents of the main breast implant manufacturers on Friday, and they have given us the go-ahead on discussing the NYU Study. I asked Tony Getty from Mentor if he was going to participate in the University of Michigan Study, and he said he was not sure but would respond early this week for a final resolution. Jan Varner said McGhan will go with us regardless. The issue of the Breast Implant Communications Center is almost completely put to bed at this point. It will be very tight for our July 8 deadline in terms of having letters out and having all the printed material ready. The final sign-off is today, June 24. The selection of people is completed and the training will begin this week. The number one issue in my mind is the establishment of networks. I believe we have made no progress in two weeks. Obviously, this is the largest single issue on our platter because it affects not only the next 2-3 years profitability of DCC, but also ultimately has a big impact on the long-term ethics and " believability " issues. If we do not win this one, or at least minimize the financial impact that our people are able to achieve, you can forget about whether we have done all these other things correctly. I know I am the " Lone Ranger " after all of our sessions on this, but I still believe appointing Burnett full time to do nothing but " orchestrate " the NETWORKS is absolutely critical! I still favor having somebody who has Page 63 " moxie " and judgment skills which are excellent to be turned loose to make the contacts to " get the ball rolling " This is critical to the patient community. While I have no problem with your approach, Barie, of turning it over to Burston Marstellar, it is a very sterile approach in the final analysis. I believe we can make faster progress on our own, even without all the communication documents established since the early part of the job is primarily getting contacts and establishing some believability as a person. It takes a lot of time to do this, and it is going to take someone like Burnett, as good as he is, a fair mount of time just to get in motion. It has become obvious to me that what is at risk here is somewhere between $50 million and $500 million. Right now, I think we are losing the " time race " badly in this critical area, and I believe that the amount of money we are going to lose is increasingly rapidly since we are not going to be in a position to divert the opposing forces into the directions we want soon. The latest information that July 5 will be a day when a legal firm in Chicago makes an announcement they have 25 women assembled who will be suing all breast implant manufacturers is just another example of how good Wolfe is in knowing when our " red-letter days " are, and anticipating and meeting them with excellent counter strategies. I fear that if he can pull it off, he may have a multi-city announcement which we are not aware of at this point. In talking to the other companies, they were not aware of the Chicago announcement, and did not know of any others beside the California group. I hope this is true, because we would be ill-prepared in terms of counter measures through the grass roots system to try to present a counter prospective. I have started to initiate the " surgeon contact sessions " by getting the people at DOW together tomorrow for an extensive development of a plan of how we want to organize the plastic surgery community and involve our ITSA organization, which should be extremely effective in this. Also, I am beginning to line up the price discussion that is desperately needed so we present a " uniform picture " to the outside community. Finally, I have been in contact with Dick Hazelton, Colin Rowland and Alain Jacquin from Europe concerning strategies there. I believe they are in good shape at this point, but it will be critical to get them rolling. I understand, Barie, you have contacted Dean, and he will be attending the press conference. I think this is good, because at this point in time after talking with the sales representatives in Europe, I am convinced they do not have the same problem yet. We obviously have a chance to get in front there, and stay there. As far as Australia is concerned, I am out of data at this point, but will get caught up. The place we have the biggest " hole " still missing and two weeks behind from the time we got the word from McKannan, is in this whole arena of getting a patient grass roots movement going. I will keep working diligently and as much as needed to help us get to " the other side, " but I am very worried Page 64 From: Myrl (myrlj@...) Subject: 1992/MFGs paid Millions/Secret Agreements - from the evidentiary files of breast implant litigation Date: 2004-05-21 06:56:08 PST Thanks to Pam Dowd for sending the following from the evidentiary files of breast implant litigation. . .Myrl PUBLICATION Montreal Gazette PUBLICATION DATE Sat 15 Feb 92 EDITION FINAL BYLINE PATRICIA ANSTETT SECTION NEWS CompuServe Mail PAGE Al2 Breast-implant firms paid millions to settle suits; Lawyers say settlements are secret because of court gag orders over decade DETROIT - Dow Corning and other breast-implant manufacturers have paid millions of dollars in out-of-court breast-implant settlements over the last decade, buying silence about implant problems through strict secrecy agreements that keep vital health information from the public, lawyers say. " Had this stuff been made public, there would have been hundreds of women today that would have never had those implants, " said Kotoske, a Palo Alto, Calif. lawyer. He has settled about 100 breast implant lawsuits since 1980, nearly all covered by secrecy agreements. Next week, some expert witnesses bound for years by these legal agreements will give testimony to a U.S. Food and Drug Administration panel. They say they no longer have to keep quiet since Dow Corning of Midland, Mich., released many top-secret documents Monday. Kotoske has won two lawsuits that breast implant manufacturers filed, alleging he broke secrecy agreements. He was one of more than a dozen lawyers interviewed nationwide who have settled out of court with manufacturers of saline-filled and silicone-gel implants. Michigan lawyers and expert witnesses told of being involved in more than 50 such cases. Hundreds of other lawsuits are pending, including more than a dozen filed in Detroit or consolidated in Chicago yesterday. " One of the reasons this information has taken so long to get to the public is because of Dow Corning's use of protective orders, " said lawyer Feldstein, who settled a case with Dow Corning. McKeenon, Dow Corning's new chief executive officer, disputed estimates of hundreds of settlements. ~Ms Page 65 From: Myrl (myrlj@...) Subject: What Dow Knew and When They Knew It: Date: 2004-10-16 20:57:44 PST What Dow Knew and When WHAT Dow Chemical Knew and When They Knew It: From: Court Documents, Internal Corporate Memos 1950: Silicones later used in breast implants by Dow Corning were bioreactive, immunogenic, toxic, and inflammatory in the human body. 1954: Dr. Spencer of Dow Chemical reported that chemical compounds of silicone gel are highly toxic. 1955: Dr. Rowe of Dow Chemical reports that materials of implant shells cause diffuse cellular infiltrates and fibrocystic changes in the lungs and organs of animals. 1956: Dow Chemical study of the biological effects of Octamethylcyclotetrasiloxane (D4), the building block of silicone gel used in implants, found if administered orally or by intramuscular injection, led to traces of siloxans throughout the bodies of laboratory animals that caused a slight initial weight loss and moderate liver pathology. 1956: Dow Chemical study of D4 found that it had a biological effect on the eye and that contact would cause painful irritation of the conjuntival membranes. Nine Dow Chemical reports indicated in test results that D4 caused irritation to the eyes and skin. One report indicated that the silicone fluid caused hyperemia, edema, and geneal skin rawness in all cases. 1956: Dow Chemical funded a research project with the University of Miami in which results found that a silicone compound (Z04141) caused deposits of silicone in the livers of laboratory rats, a fact not mentioned in the final report. 1957: Dow Corning report sent to Dow Chemical reports that: Dow Corning Fluid 200 was absorbed through the skin and found in the adrenal and kidneys of laboratory rabbits. 1961: Dow Chemical tested Dow Corning Fluid 200 when it was heat treated. The fluid caused death in all but one laboratory rat in the test. Irritation of the respiratory tract was given as the cause of death. The Dow Chemical Company, parent company of the leading manufacturer of silicone breast implants, Dow Corning, researched the health effects of exposure to commercial silicones as early as the 1940's. (See below: a partial quote of Dow Chemical Co.'s own report in the Journal of Industrial Hygiene and Toxicology by Drs. Spencer and Rowe of Dow Chemical, published in 1948. Dow Chemical and Dow Corning also conducted secret research in the 1960s that revealed that certain silicone compounds possessed sufficient biological activity to have potential uses as pharmaceuticals. Specifically, the research showed that silicones could affect the central nervous system. The companies pursued the development of silicone-based drugs for central nervous system disorders. Out of this research, the companies' scientists also learned that silicone compounds could affect the immune system. Page 66 Heyer-Schulte, a subsidiary of American Hospital Supply Corp., Dow Corning, Bristol Meyers, 3-M, the Veterans Hospital (which did testing for them), the FDA (who was warned many times but allowed these manufacturers to set their own guidelines ignored complaints and warnings from around the world about leaking implants for 30 years. A 1975 Dow Corning memo (and other implant manufacturers internal memos) state that demonstration implants were bleeding and instructed sales staff to wash the implants with soap and water and towel dry them before letting doctors handle them. The Plastic Surgeons Society was well aware of the bleeding and failure rate and wrote warning letters to these companies. A 1977 memo relates how a Dow Corning employee told plastic surgeons with crossed fingers that Dow Corning too had an active contracture/gel migration study underway. This apparently satisfied them for the moment, but one of these days they will be asking us for the results of our studies. In fact, Dow Corning was not studying contracture, a complication that occurs when the scar around the implant contracts. In 1983, Dow Corning's head of biomaterial safety wrote top company management: However, I want to emphasize that to my knowledge, we have no valid long-term implant data to substantiate the safety of gels for long-term implant use. This statement was made twenty-one (21) years AFTER Dow Corning first put silicone implants on the market and assured women that implants were safe. In a 1987 study, the Medtox Project Report, Dow Corning acknowledged that the chronic reactions to silicones seen in test animals could trigger autoimmune-type diseases in humans. In a Bristol-Meyers Squibb document from 1985, a company employee states: Polurethanes have no real history of implantation without deterioration and we know deterioration products of polyurethanes are toxic and in come cases carcinogenic. Whether they are released in such low levels as to be no threat to the human only time will tell. A 1976 3-M (Minnesota Mining and Manufacturing) document states that: It appears virtually no documented safety and efficacy data exists on (Don McGhan's) implant products. McGhan's breast implant company, McGhan Medical Corp., was purchased by 3-M. The McGhan Corp., Don McGhan, spun off from Heyer-Schulte. Heyer-Schulte Corp., spun off from Dow Corning. (See inspection photos of Corning Glass Works and Dow Chemical owners (Amory Houghton and CEO, Armistead and Dow Chemical at Dow Corning Plant.) Dr. Kessler, Commissioner of the Food and Drug Administration, reiterated in testimony before Congress in August, 1995, that the law requires manufacturers to prove affirmatively, with valid scientific data evaluated by the FDA, that their devices are safe and effective. The manufacturers have consistently failed to comply. Now they are bullying Dr. Kessler as they have all the previous FDA Commissioners. Dr. Kessler wrote in the Journal of the American Medical Association in 1993 that: the adverse effects data on silicone get implants submitted by the manufacturers were so poor that the FDA could not determine where these devices were safe and effective. He Page 67 added that the manufacturers' documents suggested that there were inadequate quality control procedures to prevent safety problems and that problems had been evident for years. Saline breast implants were never approved. There have been seven saline breast implant deaths. Three employees of Heyer-Schulte breast implant manufacturing company died of human adjuvant disease and cancer in handling silicone. Manufacturers told women that implants would last a lifetime and that ruptures occurred less than 1 percent of the time. Studies published in the American Journal of Radiology in 1992 and the ls of Plastic Surgery in 1995 reveal a rupture rate of 51 percent. A third study, published in Plastic and Reconstructive Surgery in 1993, ties rupture to the age of the implant. Of implants aged one to nine years, 35.7 percent had ruptured. Of those aged 10 to 17 years, 95.7 percent had ruptured. The FDA's own implant rupture rate on microfiche illustrates this rupture rate. The Food and Drug Commissioner, Dr. Kessler wrote in the Journal of the American Medical Association in 1993 that: Even with a conservative rupture rate, some 75,000 of the 1 to 2 million women (actually the number turned out to be only around 600,000,) would be at risk for potentially serious adverse health effects. That is NOT a safety standard that the FDA can accept. Page 68 Dow Corning Knew. . . 1968 Silicone Compounds Kill Roaches. Dow Corning has always insisted that the silicone gel in its breast implants was biologically inert, meaning that it cannot harm the body. Unfortunately, their own internal documents reveal that for almost thirty years, they've been lying. Soon after Dow Corning began marketing the implants, they tested the silicone gel for use as an insecticide. They had discovered that the silicone killed roaches. They also explored using silicone compounds to control fleas, lice, and weevils. And Dow hid other vital information. Dow filed a study claiming that four dogs used in a 1970 experiment showed no adverse effects six months after being implanted with silicone. But Dow never reported that two years after implantation, one dog was dead and the other three developed a chronic inflammation indicative of immune system problems, and similar to an affliction now seen in women with implants. If only Dow had told the truth then. In another experiement, male rabbits were swabbed with silicone. Reports show the rabbits developed a " trend toward testicular atrophy. " Biologically inert? At one time, Dow actually considered selling a silicone compound as a potent stimulator of the the human immune system. And a 1985 secred Dow report says: " The preponderance of available animal data also suggests a potential for silicone materials to be involved in immunologically mediated disease states. " Today, as more and more women are suffering immune-related disease, Dow Corning has created a smokescreen of flawed science. Meanwhile, a growing and largely ignored body of scientific literature bears out what Dow Corning's own research revealed thirty years ago--silicone implants rupture, silicone implants leak, silicone migrates throughout the body. Indeed, these implants contain a biologically active material that can affect the human immune system. Dow Corning has always insisted that the silicone gel in its breast implants was biologically inert, meaning that it cannot harm the body. Unfortunately, their own internal documents reveal that for almost thirty years, they've been lying. Soon after Dow Corning began marketing the implants, they began testing the silicone gel inside for use as an insecticide. They had discovered that the silicone killed roaches. They also explored using silicone compounds to control fleas, lice, and weevils. Page 69 And Dow hid other vital information. Dow published a study claiming that four dogs used in a 1970 experiment showed no adverse effects six months after being implanted with silicone.. But Dow never reported that two years after implantation, one dog was dead and the other three developed a chronic inflammation indicative of immune system problems, and similar to an affliction now seen in women with implants. If only Dow had told the truth then. In another experiment, male rabbits were swabbed with silicone. Reports show the rabbits developed a " trend toward testicular atrophy.

Frisch, June 10, 1969 Page 70 -71-72-73 CHRONOLOGY OF FDA ACTIVITIES RELATED TO BREAST IMPLANTS May 28, 1976: The Medical Device Amendments were enacted, giving FDA authority to regulate medical devices such as breast implants, which were already on the market. July 23, 1976: The FDA General and Plastic Surgery Devices Panel (referred to as the Panel) recommended that breast implants be placed in class II,18 requiring general controls and performance standards. January 19, 1982: Because of some reports of adverse events in the medical literature, FDA announced a proposal to place breast implants in class III. Class III devices have stringent controls for safety and effectiveness. June 24, 1988: FDA classified all breast implants into class III. After prescribed waiting period of 30 months, FDA could require the submission of premarket approval applications (PMAs) in which manufacturers present data showing the safety and effectiveness of these devices. January - March 1989: An unpublished study showed that polyurethane foam, which was used as a coating on certain types of silicone gel-filled breast implants, would degrade and release 2-toluene diamine (TDA), a chemical known to cause cancer in animals, under conditions of high temperature and alkalinity. FDA requested specific information from the manufacturer about the chemical composition and safety testing of polyurethane foam. Shortly afterwards, the manufacturer of polyurethane-coated breast implants removed them from the market May 17, 1990: FDA issued a proposed 515( regulation (call for safety and effectiveness data) in the Federal Register on silicone gel-filled implants. April 10, 1991: FDA published a final 515( regulation in the Federal Register that required manufacturers of silicone gel-filled implants to submit PMAs with data showing the safety and effectiveness of the implants by July 9, 1991. June 1991: FDA required the manufacturer of polyurethane-coated implants to conduct research on the material. In taking this action FDA made the first use of new postmarket surveillance authority under the Safe Medical Devices Act of 1990. July 31, 1991: The Panel reviewed FDA's risk assessment of polyurethane foam coating. The Panel found that the risk of cancer, if any, appears minimal and would very likely be outweighed by the surgical risk involved in removing a polyurethane-coated implant. August 22, 1991: FDA determined that PMAs submitted by three manufacturers of silicone gel-filled implants did not contain sufficient data to warrant a full review. v September 26, 1991: FDA issued a Notice in the Federal Register requiring dissemination of information to patients on the risks associated with breast implants. November 12-14, 1991: FDA convened the Panel to consider whether the PMA data received from the manufacturers was sufficient to establish that the silicone gel-filled implants are safe and effective. Despite the lack of data, the Panel voted unanimously to advise FDA that the implants filled a public health need and should continue to be available while the manufacturers collected additional data. January 6, 1992: FDA called for a moratorium on the use of silicone gel-filled implants until new safety information could be thoroughly reviewed by the Panel. February 18, 1992: The Panel met again to review new information on silicone gel-filled implants. This included case reports of autoimmune diseases; information not included in the manufacturers'original submissions to FDA; and evidence that some early models may have leaked excessively. March 19, 1992: Dow Corning withdrew from the silicone implant market, but continued to supply gel to one implant manufacturer. April 16, 1992: FDA lifted the moratorium on breast implants and announced its decision to allow silicone gel-filled implants on the market only under controlled clinical studies for reconstruction after mastectomy, correction of congenital deformities, or replacement for ruptured silicone gel-filled implants for augmentation. FDA denied applications for using silicone breast implants for augmentation but planned that the manufacturers would later conduct clinical trials that would include a limited number of augmentation patients (the stage 3 or core studies). April 16, 1992: FDA authorized limited distribution of reconstructive silicone gel-filled implants on an urgent need basis along with a very detailed informed consent form. July 24, 1992: FDA approved Mentor Corporations stage 2 or adjunct study protocol for silicone gel-filled implants for reconstruction only. December 1992: Dow Corning announced that it will no longer make five implant grades of silicone for sale after March 31, 1993, but that it will continue to manufacture 45 other medical grades of silicone materials. January 8, 1993: FDA published a 515( proposal in the Federal Register calling for safety and effectiveness data for saline-filled implants. The proposal provided for a 60-day comment period. June 2, 1994: FDA sponsored a Part 15 Hearing on saline breast implants to hear testimony from all interested parties concerning the timing of the agency's review of the safety and effectiveness of saline-filled breast implants. FDA promised to make a decision by the end of the year. July 15, 1994: FDA granted conditional approval of a pilot study of 50 patients for a breast implant filled with a purified form of soybean oil. October 21, 1994: FDA sponsored a workshop entitled, Alternatives to Silicone Breast Implants. The workshop provided a forum for FDA to present draft guidance concerning testing requirements for alternative breast implants. December 23, 1994: FDA issued a Talk Paper describing the types of studies required to demonstrate the safety and effectiveness of saline breast implants, and when the studies are expected to be completed. Pre-clinical data were submitted throughout 1995, and final clinical data are expected by early 1999. April 20, 1995: FDA updated the Patient Information Sheet on saline breast implants that manufacturers give to physicians who, in turn, provide them to patients considering implant surgery. The Information Sheet lists known and unknown risks. January 11, 1996: FDA sends a letter to current and potential manufacturers of silicone gel-filled breast implants detailing the type of information needed for core studies (stage 3 studies) of both augmentation and reconstruction patients with the silicone gel-filled implants. September 4, 1996: FDA cleared Poly Implants Prostheses (PIP) for marketing of saline breast implants through the 510(k) process. September 19, 1996: FDA received a Citizen's Petition from the Y-Me National Breast Cancer Organization and other related organizations requesting that the FDA ease restrictions on the availability of silicone gel-filled breast implants for women who choose reconstruction after a mastectomy and who have other special medical needs. February 11, 1997: FDA received a Citizen's Petition from implant recipients (who reported significant problems with their silicone implants) requesting that the FDA revoke the manufacturers' permission to make silicone gel-filled breast implants available to women with breast cancer and women who previously had implants. May 20, 1997: FDA cleared Hutchinson International for marketing of saline breast implants through the 510(k) process. FDA is currently working with saline breast implant manufacturers to submit staged submissions of preclinical and clinical data in anticipation of the call for PMAs in late 1998. October 15, 1997: FDA sent letters in response to the two Citizen's Petitions dated 9/19/96 and 2/11/97. The FDA responded to both petitioners that we do not, at this time, have sufficient information to change the current regulatory policy on silicone gel implants. FDA noted the petitioners' numerous concerns, and stated that the combination of available literature, updated PMA applications and additional ongoing studies should permit FDA to make a thorough evaluation of the safety and effectiveness of silicone gel-filled breast implants. The FDA is conducting a study to assess the rupture rate of silicone gel-filled breast implants. This study will include more than 1200 women, and medical records will be sought if their breast implants have been explanted. A sub-group of women who still have their implants will receive MRI to determine if the implants are intact. This study began in early 1998. The Department of Health and Human Services (DHHS) asked the Institute of Medicine (IOM) to conduct an independent, unbiased review of all past and ongoing scientific research regarding the safety of silicone breast implants A committee of experts in relevant scientific and clinical areas will evaluate past and ongoing studies of the relationship, if any, between implants and systemic disease; assess the biologic and immunologic effects of silicone and other chemical components of breast implant; and assess the impact of breast implants, if any, on the offspring of women with implants or the accuracy of mammograms. For more information, visit the IOM website at http://www2.nas.edu/hpdp/22f6.html March 30, 1998: FDA approved McGhan Medicals Stage 2 or Adjunct study protocol for silicone gel-filled breast implants for reconstruction only. May 6, 1998, Mentor Corporation and its subsidiary, Mentor Texas, signed a consent decree of permanent injunction, promising that the company would manufacture its breast implants in compliance with the Quality System Regulation. June 5, 1998, FDA approved McGhan medical's IDE study for silicone gel-filled breast implants for augmentation, reconstruction, and revision for a limited number of patients at a limited number of sites. ----------------------------------------------------------------- *FDA has three regulatory categories for medical devices. Class I and class II are for devices whose safety and effectiveness are well-established. Class I devices are simple devices whose risks can be controlled by the manufacturing process; class II devices require additional measures, called special controls, to control risks. Special controls may include performance standards, postmarket surveillance studies, user education or other measures. If there is a lack of information about what makes a device safe and effective, it is put into class III and the highest level of premarket review is required. Class III devices include innovative, medical breakthrough and new technology devices, as well as devices with poorly established or questionable safety and effectiveness.
