MINNEAPOLIS (AP) — Medtronic Inc., the world's largest medical device company, said Tuesday it received U.S. approval for the first pacemaker designed to be safely used with MRI scanners. Patients with the heart-pacing implants are strongly discouraged from having MRI scans because the radio waves could interfere with the functioning of their device.
CHICAGO (AP) — Many breast cancer patients can skip aggressive lymph node surgery without increasing their chances of a recurrence or death if their disease shows limited spread, according to a study that has prompted changes in practice. Under current guidelines, the often-debilitating surgery is done if the cancer has spread outside the breast to any lymph nodes.
Hughston Clinic orthopaedic surgeon, Champ L. Baker Jr., M.D., F.A.C.S ., has performed a successful knee ligament reconstruction procedure using a breakthrough medical device, ExoShapeTM CL, created by MedShape Solutions, Inc. ExoShape is a two-part, biocompatible PEEK AlteraTM interference fixation device that simplifies and improves soft tissue graft fixation during anterior cruciate ligament (ACL) reconstructive surgery.
Much of the devastation of stroke and head trauma is due to damage caused the overproduction of a substance in the brain called glutamate. Preventing this damage has been impossible, until now, as many drugs don't cross the so-called blood-brain barrier, and those that do often don't work as intended.
Never before has a therapy proven more beneficial for women than men in preventing heart disease – until now. A new study, published today in the Journal of the American College of Cardiology , found that women receive a significantly greater benefit – a 70 percent reduction in heart failure and a 72 percent reduction in death – from cardiac resynchronization therapy with defibrillator (CRT-D) than men.
Exposure to low-dose radiation from cardiac imaging and other procedures after a heart attack is associated with an increased risk of cancer, found a new study published in CMAJ ( Canadian Medical Association Journal ). The use of procedures with low-dose ionizing radiation, such as computed tomography (CT) angiography and nuclear scans, is increasing which has led to mounting concern in the medical community that patients may be at increased risk of cancer.
Lauran Neergaard, AP Medical Writer WASHINGTON (AP) — Patients don't want to hear that they're dying and doctors don't want to tell them. But new guidance for the nation's cancer specialists says they should be upfront and do it far sooner. The American Society of Clinical Oncology says too often, patients aren't told about options like comfort care or even that their chemo has become futile until the bitter end.
The concept of fast track rehabilitation program has been recently introduced in colorectal surgery. It is basically a multidisciplinary perioperative care strategy for patients after resection of colorectal cancer. A research article to be published on in the World Journal of Gastroenterology addresses this question.
Patients with kidney tumours larger than four centimetres are much more likely to enjoy good long-term renal function if they undergo nephron-sparing surgery rather than radical nephrectomy, according to a study in the February issue of the urology journal BJUI . Researchers from the Department of Urology at Johannes Gutenberg University in Mainz, Germany, studied 166 patients for up 19 years, with a median follow up of five-and-a-half years.
More students are pushing universities to make medicines more available to people in the world’s poorest countries. An article in the new issue of the Journal of International Affairs examines “humanitarian licensing.” The movement argues that universities that own the rights to medicines they develop should ensure they are available to people in need, according to Journal contributing author Bhaven N.
Maria Cheng, AP Medical Writer LONDON (AP) — The world is becoming a heavier place, especially in the West. Obesity rates worldwide have doubled in the last three decades even as blood pressure and cholesterol levels have dropped, according to three new studies. People in Pacific Island nations like American Samoa are the heaviest, one of the studies shows.
While hand gestures are nothing new to the operating room, surgeons of the future might use a system that recognizes hand gestures as commands to control a robotic scrub nurse or tell a computer to display medical images during an operation. Both the hand-gesture recognition and robotic nurse innovations might help reduce the length of surgeries and the potential for infection, states Juan Pablo Wachs, an assistant professor of industrial engineering at Purdue University.
The pediatric cardiac team at Oregon Health & Science University Doernbecher Children's Hospital is the first in the region and one of a handful in the nation to implant a pulmonary heart valve without open-heart surgery. To date, four patients have received the valve in the OHSU Pediatric and Adult Congenital Cardiac Catheterization Lab.
Greg Bluestein, AP A federal lawsuit filed against the Food and Drug Administration urges a judge to block imports of a key drug used in the nation's executions that has been in short supply since the sole U.S. maker decided to stop producing it. The lawsuit claims the FDA has knowingly allowed state corrections officials to import sodium thiopental, the sedative used in a three-drug execution cocktail, that has not been approved by the agency.
(AP) — The VA Medical Center in St. Louis has halted surgeries after a regular inspection showed possible contamination of equipment. The hospital's medical director, RimaAnn O.
