Women with an identical twin sister are up to four times more likely to go through menopause much earlier than fraternal twins, or even other women in general. That's according to a new government study that followed 800 twins through menopause. The reasons behind the link between twins and early menopause are unclear, but researchers think it has something to do with the embryo splitting process.
Doctors often look at flat images on computers to understand the progression of disease. Now a new visual tool literally spins a 3-D image into view. The Perspecta Spatial 3-D system is being put through its paces at Rush University Medical Center in Chicago. The domed viewer houses a spinning computer screen. The high speed rotation visually combines hundreds of digital image slices into a single, floating 3-D image. Doctors can double check radiation treatment plans by looking at tumors from all angles, ensuring radiation hits the whole tumor while avoiding healthy tissue.
When it comes to the face, Botox isn't just for erasing fine lines. Researchers have found that it can also ease intense facial pain. People suffering from the disorder called Trigeminal Neuralgia often have sudden, stabbing pain on one side of the face. Normal, everyday activity such as talking and brushing teeth can trigger horrible attacks. Researchers at Thomas Jefferson University Hospital in Philadelphia says ten days after Botox injections on the face, the pain was significantly decreased for 100 percent of the patients in a study. Also called Tic Douloureux, the disorder is more common in women than in men and typically affects those older than 50. The study included 13 patients. Researchers say there were no major side effects. They followed the patients for 60 days.
