Preclinical Bioassay of a Polypropylene Mesh for Hernia Repair Pretreated with Antibacterial Solutions of Chlorhexidine and Allicin: An In Vivo Study. Toxic Chemicals Released From Polypropylene Plastic. By Brenda Fulmer This story from Advancing Green Chemistry, a group dedicated to finding healthier alternatives to harsh chemicals, concerns a research article in June 2010 studying the toxicity of polypropylene plastic used in sutures and hernia and transvaginal mesh.
A study out of Austria and the Institute of Analytical Chemistry states that the amount of stabilizers in commercial petroleum-based plastics used in polypropylene (PP) are usually undercounted. Besides medical devices such as transvaginal and hernia mesh, PP is commonly used to make plastic blinds and indoor-outdoor carpets.
Talc–filled polypropylene can be found in household appliances and car parts, syringes, test tubes and other medical equipment. Even the hula hoop was made of Marlex, the commercial name for polypropylene.Its cost-to-performance ratio is one of the determining factors for its use over alternatives, such as polycarbonate and polystyrene, according to the chemical consultancy group, Frost & Sullivan. De gevaren waarvan de chemiereuzen niet willen dat u ze kent - Wetenschap. Identification of degradation products of antioxidants in polyolefins by liquid chromatography combined with atmospheric pressure photoionisation mass spectrometry.
Abstract Round robin tests have revealed the trend that the concentration of stabilizers in polyolefins is usually underestimated.
However, it is still unclear whether this underestimation is due to systematic errors of the analysis procedures or to degradation of the stabilizers during the production of the round robin sample itself. Within the present work, the degradation pathways of six common antioxidants (ADK Stab AO-60, Everfos 168, Kinox 30, Irganox 3114, Irganox 1076, and Cyanox 1790) were investigated. Methods based on high-performance liquid chromatography with UV detection or hyphenated with mass spectrometry (employing either an ion trap or a quadrupole/time-of-flight instrument) were developed, whereby the suitability of atmospheric pressure photoionisation was studied and compared with the performance of more established ionisation techniques like electrospray ionisation and atmospheric pressure chemical ionisation.

Boston Scientific has been sued under the Racketeering and Corrupt Organizations Act (RICO) for allegedly orchestrating a conspiracy to sell misbranded transvaginal mesh made from counterfeit plastic smuggled from China.
Qmed News. Boston Scientific accused of using counterfeit ingredients - Crossroads Today. By Jackie Wattles NEW YORK (CNNMoney) -- A class action lawsuit against Boston Scientific made public Thursday alleges the company used counterfeit material from China to manufacture toxic vaginal mesh implants.
The suit filed in a West Virgina federal court is yet another in the mounting litigation that's been brought against makers of vaginal mesh implants. Patients have said the devices caused miscarriages and other severe medical issues. A few cases have been settled, and more than 70,000 civil lawsuits have been consolidated into an ongoing case playing out in federal court. The West Virgina suit goes beyond the claims made in those cases. If the allegations are substantiated, Boston Scientific could face criminal charges and even heftier payouts than it would in other civil cases.
Boston Scientific accused of using counterfeit pellets in pelvic. Attorneys for a West Virginia woman suing the makers of a product used to treat pelvic organ prolapse and urinary incontinence claim confidential documents the company turned over in related complaints suggest some of the mesh being implanted in women isn’t even the real deal.
The complaint, which names Teresa Stevens as lead plaintiff, was filed Friday, Jan. 15 in federal court in Charleston by attorneys with the Houston, Texas-based Mostyn Law Firm and Harry Bell of Harry F. Bell Law in Charleston. It alleges Boston Scientific, maker of Advantage mesh, panicked a decade ago when its U.S. supplier cut off its supply of Marlex, the pellets used to make Boston Scientific’s mesh products, and substituted a counterfeit product its people found in China without notifying the women in whom it was implanted or the U.S.
Food & Drug Administration of the change. Mostyn Law: RICO case targets company over tainted vaginal implants. HOUSTON, Jan. 14, 2016 /PRNewswire-USNewswire/ -- Mostyn Law, a Houston-based firm, has accused a leading U.S. medical company of running an international conspiracy that sold defective vaginal surgical mesh, made of counterfeit supplies it smuggled from China.
The firm, headed by attorneys Amber and Steve Mostyn, sued Boston Scientific Corp. and three other companies under the Racketeering and Corrupt Organizations Act (RICO) on behalf of women who have suffered severe discomfort, bleeding, infections, painful intercourse, urinary problems and other complications from the plastic mesh implants. The class-action lawsuit says that after losing its U.S. supplier of the synthetic resin to produce the mesh, Boston Scientific bought unverified, substandard material from a known counterfeiter in China.
The company took extraordinary measures to avoid being caught by U.S. and Chinese authorities, at times acting like a drug dealer to hide multiple overseas shipments, the suit says. The U.S. Possible allergy to polypropylene mesh. Thank you for your inquiry.
We have dealt with a very similar question regarding a possible allergic reaction to polypropylene mesh. For your convenience, I have copied the previous question and our response below which was posted on 4/25/2012. Unfortunately, I could find no additional studies in the literature since that response was posted. As you can see from our answer to the previous inquiry, there is a dearth of scientific literature in this area. However, I would interpret any testing in this area with caution since, at least according to the review of the literature that I have made, there is no available standardization of testing that has been published allowing one to distinguish normal from sensitized individuals. Thank you again for your inquiry and we hope this response is helpful to you. Patent US3054406 - Surgical mesh - Google Patents. Mostyn Law calls on FDA and Boston Scientific to Stop the Use of Counterfeit Surgical Mesh.
HOUSTON, Jan. 27, 2016 /PRNewswire-USNewswire/ -- A federal judge in West Virginia urged a plaintiff in a lawsuit against Boston Scientific Corp. to ask the Food and Drug Administration (FDA) to investigate the company's use of a plastic resin from China to make vaginal surgical mesh.
The Jan. 26 decision by U.S. District Judge Joseph Goodwin in Charleston, West Virginia, directed plaintiff Teresa Stevens to ask the FDA for a determination on the safety of products made by Boston Scientific Corp. The plaintiff filed a lawsuit claiming Boston Scientific used counterfeit resin smuggled from China. Judge Goodwin said the regulatory agency should be given the first opportunity to decide whether Boston Scientific's mesh should be banned for use in vaginal implants under the doctrine of "primary jurisdiction. " This doctrine allows a judge to halt a case while a regulatory agency determines technical matters.
