Calcium isotope analysis used to predict myeloma progression

The researchers tested a new approach to detecting bone loss in cancer patients by using calcium isotope analysis to predict whether myeloma patients are at risk for developing bone lesions, a hallmark of the disease. They believe they have a promising technique that could be used to chart the progression of multiple myeloma, a lethal disease that eventually impacts a patient’s bones. The method could help tailor therapies to protect bone better and also act as a way to monitor for possible disease progression or recurrence. “Multiple myeloma is a blood cancer that can cause painful and debilitating bone lesions,” said Gwyneth Gordon, an Associate Research Scientist in ASU’s School of Earth and Space Exploration, and co-lead author of the study…

7 warning signs you should not ignore

A few days after Melissa Daly broke her ankle, the calf above it became tender. Within a week, her foot was dark purple. She saw her doctor, who dismissed it as normal bruising and offered a prescription for painkillers. The drugs didn't help, and a week later she woke up in the middle of the night gasping for air.  “I felt like I was suffocating,” she said. Her husband called 911, and within an hour she was on a respirator in the ER. A blood clot had broken off from her calf and lodged in her lungs. The agony she felt is one of seven pains you should never brush off. Read on to make sure that your nagging aches are as innocent as they seem. MORE: 7 Lies We Tell Our Doctors Severe Head Pain This mother of all headaches makes your bachelorette party hangover seem laughable. If you could laugh. The culprit: Odds are, any jackhammering in your brain is just a migraine. But if it's not accompanied by other migraine symptoms (such as a visual aura), sudden and severe pain -- we're talking the absolute worst headache of your life -- can signal a brain aneurysm.  These arterial bulges occur in up to 5 percent of people, but most of the time they don't cause any trouble -- you won't even know you have one unless the weak spot leaks or tears. If that happens, escaping blood can flood the surrounding tissue (causing a violent headache) and cut off the oxygen supply there. Smoking and having a family history of aneurysms increase your odds. The fix: “A burst aneurysm can cause brain damage within minutes, so you need to call 911 immediately,” Dr. Elsa-Grace Giardina, director of the Center for Women's Health at NewYork-Presbyterian Hospital/Columbia University Medical Center, said.  Your doctor will take a CT scan to look for bleeding in the space around the brain. If he finds hemorrhaging, you'll head into the (operating room) pronto for surgery to repair the blood vessel. Throbbing Tooth Spooning your way through a pint of Chubby Hubby has become an exercise in torture. When your teeth touch anything frosty, you feel a dull throb or sharp twinge. The culprit: It's likely that the tooth's nerve has become damaged, usually because the surrounding pearly white is cracked or rotting away. Unless you get it patched up quickly, bacteria in your mouth can infect the nerve. And you definitely don't want that breeding colony to spread throughout your body, said Kimberly Harms, a dentist outside St. Paul, Minnesota. The fix: Time for a cavity check! You may just need a filling to cover the exposed nerve. But if it's infected, you're in for a root canal, in which the tooth's bacteria-laden pulp is removed and replaced with plastic caulking material. Antibiotics can clear up any infection that has spread beyond the mouth. MORE: The 10 Self-Checks Every Woman Should Do Sharp Pain In Your Side A typical runner's side stitch pales in comparison to this piercing stab, which intensifies over a few hours or days. The culprits: You may just need some Beano. But if you feel as if you're being skewered in your right side and you're also nauseated and running a fever, you could have appendicitis. It occurs when something (like a stray piece of feces) migrates into the space where the appendix empties into the colon, blocking it. Soon the organ becomes dangerously inflamed.  Another possibility is an ovarian cyst. Typically these fluid-filled sacs are harmless and disappear on their own. But if one twists or ruptures, it can cause terrible pain. The fix: In both cases, you're looking at emergency surgery.  “If you don't remove an inflamed ap­pendix, it can burst,” Dr. Lin Chang, a gastroenterologist and co-director of UCLA's Center for Neurovisceral Sciences and Women's Health, said.  This can cause dangerous swelling of the tissue surrounding your organs. A twisted cyst also needs to be removed right away, as it can block blood flow to your ovary within hours. If that happens, the doctor will need to cut out the entire ovary (and the eggs inside) along with the cyst. Passing Chest Pain Periodically, you get what feels like a bad case of heartburn, or a tight squeezing sensation, as if you're being laced into a corset. The culprit: You probably just peppered your pizza with too many chilis. But if you know you're at risk for heart problems, don't blow it off -- it could be a heart attack. Every year, about 10,000 women under 45 have one. Symptoms tend to be less severe in women than in men, so “you may just feel pressure, along with fatigue, throat pain, or shortness of breath,” Giardina said. The fix: Feel the burn after feasting on chalupas? Normal. Feel as if you're being squeezed to death by a boa constrictor after a hard workout?

Vocal cord paralysis: Explaining Google CEO Larry Page’s rare condition

Earlier this week, Google CEO Larry Page finally revealed the reason behind his soft, hoarse-sounding voice: he suffers from a rare condition called vocal cord paralysis Though Page was able to speak on Wednesday at Google I/O, the company’s annual developer conference, he recently wrote on his Google Plus profile that he has struggled with vocal cord paralysis for the past 14 years. Page said he was first diagnosed with paralysis in his left vocal cord after a bad cold. However, his condition worsened last summer when his right vocal cord also became paralyzed. Experiencing paralysis in both vocal cords is extremely uncommon, according to Dr. Nicole Maronian, director of the Voice Center at University Hospitals Case Medical Center in Cleveland, Ohio, who did not treat Page for his condition. “Since I’ve been in practice, since 1998, it’s been one patient. Having it affect both vocal cords, it’s pretty rare,” Maronian told FoxNews.com. Normal vocal cords open and then close completely every time they are stimulated by the nerves. “They have to close in a tight line to get the kind of strong voice out that you and I have today,” Maronian said. But when vocal cords become paralyzed, they are not able to close completely, leaving a gap.  “If there’s a gap, air starts leaking through, and you start sounding breathy, softer,” Maronian explained.   In addition to hoarseness, patients with this paralysis can also experience shortness of breath due to air leaking through the gap between the vocal cords. “They often get a little bit high-pitched, trying to project or pitch the voice. They get short of breath because of all that air leaking out, or have trouble getting full sentences out because of the air leaking out,” Maronian said. Some patients even experience aspiration, when recently swallowed fluids leak through the space in between the vocal cords. Aspiration can lead to coughing symptoms or even “aspiration pneumonia, which has significant morbidity and mortality,” Maronian said. While the paralysis is typically thought to be caused by a viral infection, such as a cold, pneumonia or bronchitis, other factors may be to blame as well.   “Lots of things can affect the nerve: A virus, compression from a thyroid issue, other things like cancer, (or) surgeries where the nerve is ether stretched or pulled,” Maronian said. Page disclosed that he was also diagnosed with Hashimoto’s thyroiditis in 2008, an inflammation of the thyroid gland, which may or may not affect his vocal cord paralysis. “Sometimes the thyroid gets big which can compress the nerve and push on it. Usually though, the gland burns out and gets small and the nerve compression issue isn’t a piece of it anymore,” Maronian said. Recovery time for vocal cord paralysis can vary. Some patients rebound within months, while others take much longer to heal, Maronian noted. Depending on the needs of the patient, doctors can offer several treatment options for vocal cord paralysis. Patients can wait and see if the condition improves on its own, but many opt for vocal cord injections or surgical procedures to achieve faster relief and recovery. “In the office or operation room, we can (inject) a material next to the vocal cord that pushes it into a more natural position, so it can get closure. (We then) watch and hope it recovers on its own,” Maronian said. Page said in his statement that he plans to “fund a significant research program” through the Vocal Health Institute, led by Dr. Steven Zeitels from the Harvard Medical School and the Massachusetts General Hospital Voice Center.source : http://www.foxnews.com/health/2013/05/16/vocal-cord-paralysis-explaining-google-ceo-larry-pages-rare-condition/

How to deal with bad behavior at the gym

The etiquette of dealing with space invaders, circuit breakers and other gym scourges. Space Invaders Problem: You finally make it to yoga class, but just as it begins, a latecomer places his mat inches from yours. Now you can’t salute the sun without smacking your neighbor’s back. Solution: Confront, but in a nice way. “Always begin your approach with the thought that most people aren’t rude on purpose,” Liz Neporent, exercise physiologist and a coauthor of “The Fat-Free Truth,” said. “They’re simply wrapped up in their own little worlds.”  You could say something like, “Excuse me, but I’m going to need a little extra room here,” suggested Dee Poquette, a personal trainer in Danbury, Connecticut. If politeness fails, move to another spot or take the matter to a higher authority. Chances are the gym or studio may be overselling classes. Loud Talkers Problem: You’re thoroughly engrossed in a magazine, cycling toward your eight-mile goal, when a woman on the machine behind you answers her cell phone and proceeds to discuss her dinner plans at full volume. Solution: Say something, but keep your tone pleasant and nonaccusatory. You can say, “Excuse me, but your conversation is distracting―would you mind talking off the gym floor?” If you don’t want to get directly involved, ask an employee to intervene.  “The proble mis that many clubs don’t ban cell phones,” John McCarthy, a former executive director of the International Health, Racquet & Sportsclub Association, said.  If yours doesn’t, try moving to another part of the gym or wearing headphones. Smelly Patrons Problem: As you work yourself into an elliptical frenzy, a strong whiff of your most hated perfume (or, worse, body odor) wafts your way, and you feel as if you’re going to suffocate or faint. Solution: Move away, if possible. But if you’re stuck in close quarters, there’s little you can do beyond discreetly taking your complaint to a manager.  “When the issue is personal grooming, we prefer members to come to us,” Steven L. Schwartz, chief executive officer of Midtown Athletic Clubs in Chicago, said. “It’s uncomfortable for someone to tell another person that he smells bad.”      Sometimes the issue is ignorance or, in the case of body odor, inattention. Poquette recalled when one client’s odor lingered long after he had left the room, bothering other clients.  “It turns out he would work out and put his clothes in the locker, then put the same clothes back on two days later,” she said. “As soon as someone pointed out the issue, the problem was straightened out. You’d think he could tell, but he was oblivious.” Circuit Breakers Problem: As you’re zooming around the machines, which are clearly labeled 1 through 9 for circuit training, you see someone position herself on the shoulder press―your intended next stop. Solution: “A certain amount of jumping in on a circuit is acceptable, provided the person doesn’t block someone who’s going through in order,” Neporent said. “If someone is about to block you, you can say, ‘I’m following the circuit, and I’m about to use that machine.’ ”      If she blocks you anyway, keep going around and come back to the machine later to maintain the flow of your workout. Circuit etiquette is a bit different from general weight-room etiquette in that you’re expected to let another person use your machine―that is, “work in”―while you rest or do cardio between sets. Should a response to your “May I work in with you?” be less than friendly, simply back off or take the matter to the trainer on duty. You’re not tattling.      “Things like that have a way of boiling over in gyms,” Denis Barry, a co-owner of Edge, a gym in New York City, said.
