MRI recordings at one fiftieth of a second

"Please hold absolutely still": This instruction is crucial for patients being examined by magnetic resonance imaging (MRI). It is the only way to obtain clear images for diagnosis. Up to now, it was therefore almost impossible to image moving organs using MRI. Max Planck researchers from G-ttingen have now succeeded in significantly reducing the time required for recording images - to just one fiftieth of a second.

New non-invasive method to diagnose osteoarthritis

Researchers at New York University have developed an innovative way to look at the development of osteoarthritis in the knee joint-one that relies on the examination of sodium ions in cartilage. Their work, which appears in the Journal of Magnetic Resonance, may provide a non-invasive method to diagnose osteoarthritis in its very early stages.

World's tallest man undergoes Gamma Knife surgery

Much of Sultan Kosen's eight feet, two-inch stature rose up in an 17-year period starting at age 10, when the benign tumor in his brain's pituitary gland highjacked the organ, causing it to secrete massive amounts of growth hormone, making Mr. Kosen's body grow fast and grow without ceasing. He will need to wait several months to find out if his Gamma Knife® surgery last Thursday at the University of Virginia (UVA, Charlottesville, Va.) has inactivated the tumor and he has reached his final height, but his physicians are optimistic.

Researchers develop magnetic nanoparticles for metallic implant drug delivery

If a drug can be guided to the right place in the body, the treatment is more effective and there are fewer side-effects. Researchers at Lund University in Sweden have now developed magnetic nanoparticles that can be directed to metallic implants such as artificial knee joints, hip joints and stents in the coronary arteries.

Asia's first 'custom fit knee replacement surgery' performed at Fortis Hospitals

Combining the latest technology, medical breakthroughs and personalized patient care, Fortis Hospitals Bangalore today announced Asia's first 'Custom Fit Knee Replacement Surgery' performed on a series of patients. Dr. Sanjay Pai, Chief Orthopedic Surgeon, along with his team performed this revolutionary surgery for the first time in the Asian Continent by precisely matching the size and placement of the implant specific to the patients' knee size. This procedure ensures lesser pain, less tissue damage, faster mobilization and longer lasting implant solution.

Early year-round sports specialization contributes to rise of overuse injuries

Bobby Boyle engages in serious year-round sports training and has had his share of minor muscle injuries. When the 12-year-old athlete felt tightness in the back of his thigh while sprinting at track practice, he and his parents thought he pulled a hamstring and assumed it would heal with limited exercise time.

'Rotten eggs' gas inside knee joint protects against inflammation

Hydrogen sulfide (H2S) is a gas more commonly associated with the smell of 'rotten eggs' and blocked drains. However, it has now been shown to be present naturally in our bodies and reside in knee joint synovial fluid, the protective fluid found in the cavities of joints that reduces friction between the cartilage of joints during movement. Synovial fluid H2S may play a role in reducing inflammation in joints.

FDA Advisory Committee votes in favor of expanding pain indications for Eli Lilly's Cymbalta

The U.S. Food and Drug Administration (FDA) Anesthetic and Life Support Drugs Advisory Committee voted 8-6 in favor of expanding the pain indications for Eli Lilly and Company's (NYSE: LLY) Cymbalta® (duloxetine HCl) to a broader pain population that will be further defined by the FDA, if approved.

Study finds no clinical benefits from gender-specific total knee prostheses for women

A gender-specific total knee prosthesis was developed to more closely match the anatomy of the female knee, aiming to be a better fit resulting in better outcomes for women. However, a recent study in the Journal of Bone and Joint Surgery (JBJS) found that 85 women who received a gender-specific implant in one knee and a standard prosthesis in the other knee found no clinical benefits of the gender-specific knee.

Cluster-coated implant strengthens attachment of joint-replacement implant with bone

Researchers have developed an improved coating technique that could strengthen the connection between titanium joint-replacement implants and a patients' own bone. The stronger connection created by manipulating signals the body's own cells use to encourage growth could allow the implants to last longer.

Hearing loss in adolescents on the rise

Hearing loss is now affecting nearly 20 percent of U.S. adolescents age 12-19, a rise of 5 percent over the last 15 years, according to a new Journal of the American Medical Association (JAMA) study co-led by Ron Eavey, M.D., director of the Vanderbilt Bill Wilkerson Center and the Guy M. Maness Professor in Otolaryngology.

Study finds sham acupuncture superior to traditional Chinese acupuncture in osteoarthritis treatment

Researchers from MD Anderson Cancer Center determined patients with osteoarthritis (OA) of the knee who are treated with traditional Chinese acupuncture (TCA) do not experience any more benefit than those receiving sham acupuncture (placebo). The team did find that the communication style of the acupuncturist could have a significant effect on pain reduction and satisfaction in patients. Full findings are now online and will publish in the September print issue of Arthritis Care & Research, a journal of the American College of Rheumatology.
