A clinical trial being conducted at several high-profile centers in Canada has begun recruiting patients to investigate a new, non-surgical treatment for lower back pain caused by a contained herniated disc. The trial is studying a minimally invasive injection of natural gases designed to dissolve a small amount of disc tissue in order to resolve the disc herniation.
A survey of 13,860 patients who had undergone interventions for aortic valve disease has revealed that over 80 percent were in the same or a better state of health one year after the intervention. Aortic stenosis is the most frequent valvular heart disease in the aging Western population, and the prognosis of this disease in symptomatic patients with conservative therapy is poor.
Dr. Oren Tessler, Assistant Professor of Clinical Surgery at Lousiana State University, is part of a team of plastic and reconstructive surgeons who report a high success rate using a method to screen and select patients for a specific surgical migraine treatment technique. More than 90% of the patients who underwent this surgery to decompress the nerves that trigger migraines experienced relief and also got a bonus cosmetic eyelid surgery.
Controlled application of vacuum pressure is a promising approach to limiting tissue damage after traumatic brain injury (TBI). In the study, which was funded by a major grant from the U.S. Army, the researchers tested the mechanical tissue resuscitation approach by inducing localized TBI in swine, then applying negative pressure—that is, a mild vacuum—over the injured area of the brain.
CrowdOptic, a maker of mobile and wearable broadcasting solutions, announced its working with the Department of Cardiothoracic Surgery at Stanford University Medical Center to help improve resident training in complex surgical procedures, through the use of Google Glass technology. CrowdOptic's software lets one Google Glass wearer inherit another's point of view, simply by looking in the other user's direction.
A report released Tuesday by the acting U.S. surgeon general cited an alarming 200 percent jump in deadly melanoma cases since 1973. The report blames a generation of sun worshipping for the $8 billion spent to treat all forms of skin cancer each year.
“It a very competitive award, which validates the uniqueness of this polymeric nanofilm technology. A significant merit is that the concept is adaptable to delivery of a wide range of bioactive molecules on tissue surfaces, providing a broadly applicable healthcare materials platform,” said co-founder Nicholas Abbott, PhD, Professor in Department of Chemical and Biological Engineering at University of Wisconsin-Madison.
"Stem cells offer tremendous potential, but the marketplace is saturated with unsubstantiated and sometimes fraudulent claims that may place patients at risk," write Dr. Michael T. Longaker of Stanford University Medical Center and colleagues. To date, just one stem cell procedure for cosmetic purpose has received FDA approval, after extensive evaluation.
With a new technique, researchers at the University of Pennsylvania have established a new strategy to help surgeons see the entire tumor in the patient, increasing the likelihood of a positive outcome. This approach relies on an injectable dye that accumulates in cancerous tissues much more so than normal tissues. When the surgeon shines an infrared light on the cancer, it glows, allowing the surgeon to remove it.
Patients who are placed in contact isolation after their operations are at a particularly high risk for developing life-threatening blood clots, but ensuring they move around has helped curb the occurrence of venous thromboembolism in one hospital.
A new study, published in the July, 2014, issue of the Journal of the National Cancer Institute by Northwestern Medicine® researchers, sheds new light on the risks associated with the growing popularity of endoscopic resection in the treatment of localized, early-stage esophageal cancer. The study reviewed the outcomes of more than 5,000 patients from 824 hospitals.
Compared with complication rates in 2009, mortality rates dropped by 31.5 percent. The collaborative saw improvements in 13 of the 17 types of complications, and nine improved significantly. The areas of most improvement included surgical site infections, pneumonia and urinary tract infections, which all dropped by approximately one-third.
A revised version of a surgical procedure to treat severe chronic migraine headaches led to significant symptom relief more than 90 percent of the time in patients treated at Massachusetts General Hospital (MGH). "We confirmed that surgery through standard incisions used for cosmetic procedures can be very effective in treating some of the most severe cases of chronic migraine," says William G. (Jay) Austen, Jr., MD.
A team of researchers have created a biodegradable biomaterial that is inherently antioxidant and can be used to create elastomers, liquids that turn into gels, or solids for building devices or implants that are more compatible with cells and tissues, reducing inflammation or rejection.
The project's goal was to reduce the cardiac NSQIP SSI rate to two percent. The team succeeded in lowering the infection rate to a NSQIP average of 1.6 percent in the nine months after fully instituting the surgical best practices bundle.
