Breast implant fears put focus on biomaterials
Article Abstract:
The polyurethane coating of some of the breast implants made of silicon can break down in the body, releasing a material that can lead to the development of cancer. The breakdown of the coating by the body was not surprising to biomaterial scientists and some clinicians, and evidence of some cancer-causing by-products of the breakdown has been reported in the literature for over a year. There is an increased need for materials that are more compatible with the body. Biomaterials are needed in many areas of medicine, for example: in cardiology, for replacement parts of the heart, such as bypass grafts and heart valves; in dentistry, for tooth substitutes; and in ophthalmology, for lenses for the eyes. Biomaterials could also be used in joint and ligament replacement, in drug delivery systems, and as filters of the blood. There is a proposal for a 10-year $250 million-per-year biomaterial program. Long-term funding is needed so that a systematic approach can be taken to develop biomaterials. It is hoped that the products could be rapidly commercialized so that revenues for further research could come from the progress of the research. All the materials that are currently used break down and can be toxic or can cause an immune reaction. Biomaterials can be compatible in one part of the body but not in another part, so any materials developed must be analyzed for use in various parts of the body.

Breast-implant ruling sends a message
Article Abstract:
Federal judge Robert E Jones, faced with a long list of expert witnesses in a case claiming a link between breast implants and autoimmune disorders, assembled his own panel to exclude some evidence before the trial. His procedure may set a precedent for large suits involving scientific evidence.
