A unit of y-ray attenuation used for CT-scans as a measurement of bone density. Each pixel is assigned a value on a scale on which air is -1000, water 0, and compact bone +1000.

In dentistry exists a proposal to use bone density as a determinant for clinical success (Misch CE, Contemporary Implant Dentistry, St. Louis Mosby, 1999: 109-118).

Concerns about shortages of orthopaedic implants due to the EU Medical Device Regulation

February 16, 2024The German Society for Endoprosthetics (AE) is concerned about potential shortages of artificial hip and knee joints. Bureaucratic hurdles urgently need to be removed, as otherwise the EU Medical Device Regulation (MDR) would increasingly jeopardize patient safety, it said today. The MDR, which came into force in 2021, has been criticized since its inception and the warnings issued at the time seem to be increasingly coming true: Specialized medical devices in particular, which are manufactured in small quantities, are increasingly disappearing from the supply chain. In addition to reducing bureaucratic hurdles, the association is therefore also calling for a simplified approval and recertification process in order to safeguard care and continue to enable innovation. Only this would make it possible to bring implants for special requirements onto the market quickly and unbureaucratically and ensure modern and patient-oriented medical care.

Testing company to pay more than ten million euros in breast implant scandal

January 12, 2024In the scandal surrounding defective breast implants from French manufacturer Poly Implant Prothèse (PIP), a court has ordered TÜV Rheinland to pay more than ten million euros. The testing company must compensate 605 of 1,319 plaintiffs. Most of the women in these proceedings come from Great Britain. The court stated that from 2002 onwards, there had been a discrepancy at PIP between the quantity of gel ordered for the breast implants and the number of prostheses produced. This should have been noticed. The TÜV’s lawyer criticized the ruling and recommended an appeal. From 2001 to 2010, PIP sold around one million of the poor-quality implants worldwide. 400,000 women suffered damage to their health. In Germany, Belgium, Italy and Spain, complaints have been dismissed, emphasized TÜV Rheinland. Only in France are there still legal disputes. According to its own information, TÜV Rheinland did not test the implants of the manufacturing company PIP, but certified the company’s quality management system. In 2016, PIP founder Jean-Claude Mas was sentenced to four years in prison and a fine of 75,000 euros for serious fraud and deceiving TÜV. He died in 2019.

Implant reduces intraocular pressure

December 29, 2023The US Food and Drug Administration (FDA) has approved an intraocular implant for the treatment of open-angle glaucoma or ocular hypertension. The capsule placed in the angle of the chamber continuously releases the prostaglandin analog travoprost, which improves the outflow of aqueous humor. The implantation of “iDose” frees patients from the daily use of eye drops. It is implanted in the iridocorneal angle between the cornea and the iris. There it penetrates the sclera with its tip, where it is firmly anchored with a barb. The most common ocular side effects, which occurred in 2 % to 6 % of iDose TR patients, were increases in intraocular pressure, iritis, dry eyes and visual field defects, which were mostly mild and improved on their own.

A Double-Lung Transplant and a Pair of Breast Implants to Save a Life

December 21, 2023The patient, had a history of vaping and multiple infections, first viral infections and then Pseudomonas pneumonia. He had a really severe infection in both lungs. He was ventilated but the ventilator was not sufficient to keep him alive. He was then placed on the extracorporeal membrane oxygenation (ECMO), and he was dying on the ECMO, with no other options for him at that time. He was failing antibiotic treatments, and unfortunately, ECMO was not bridged for his survival or improvement. The hope, of course, is that bypassing the heart-lung system allows the lungs times time to heal and eventually you can wean the patient off ECMO, back to the ventilator, and then off the ventilator. But this was not the case here. In his current condition, he was not a candidate for a lung transplant. We came to idea to actually remove the lungs from the patient. The patient would be living without his lungs while we waited for new lungs to be available from a donor. We had to create artificial channels in the heart, reconnecting the right and left side of the body and implanting oxygenators to take over the function of the lungs. The heart was beating in a chest cavity in the absence of lungs stabilizing it from either side. To keep the heart stable two breast implants were put on either side of it. When the transplant lungs arrived, the breast implants were removed and the lungs were put in. Now the patient is out of the hospital, out of rehab, and here, at his temporary home in Chicago and doing really well.
