New technique alleviates painful bone metastases, study suggests

During the procedure, known as MR-guided focused ultrasound, doctors direct a concentrated beam of energy to specific nerve endings that are causing pain in bone metastases. These patients typically have a significant amount of discomfort — half of study participants rated their pain at least a 7 out of 10 — but within a handful of days, most said they felt significant relief. Although Fox Chase patients received local anesthesia during the procedure, the most commonly reported side effect was pain — which can often be alleviated with additional anesthesia, says study author Joshua Meyer, MD, attending physician in the Radiation Oncology Department at Fox Chase. "That’s temporary pain, which is gone as soon as the procedure is over," he says…

Brain makes call on which ear is used for cell phone

The study — to appear online in JAMA Otolaryngology-Head & Neck Surgery — shows a strong correlation between brain dominance and the ear used to listen to a cell phone. More than 70% of participants held their cell phone up to the ear on the same side as their dominant hand, the study finds. Left-brain dominant people — who account for about 95% of the population and have their speech and language center located on the left side of the brain — are more likely to use their right hand for writing and other everyday tasks. Likewise, the Henry Ford study reveals most left-brain dominant people also use the phone in their right ear, despite there being no perceived difference in their hearing in the left or right ear…

New mechanism leading to tumor hypoxia defined

Growing evidence from experimental studies and clinical trials suggests a fundamental role of hypoxia in solid tumors. The mechanisms leading to hypoxia include the rapid rate of tumor growth, poor tumor perfusion or transiently disrupted tumor blood flow…

iPad 2 could interfere with pacemaker, study shows

A California teen discovered the magnets in iPad 2 tablets and covers are capable of interfering with cardiac rhythm devices, like pacemakers, according to the Heart Rhythm Society. The research, conducted by 14-year-old Gianna Chien of Stockton, Calif , was presented Thursday at Heart Rhythm 2013, the Societyâ€™s 34th Annual Scientific Sessions. â€œiPad 2s use magnets to help secure the cover to the tablet. Since people hold tablets so close to their chest, I wanted to see if these magnets could affect cardiac device performance,â€� said Chien, who initially organized the study as part of a school science fair project. …
