Experts worry over possible link between child CT scans and cancer

Fewer CT scans were done on American children in recent years after a steep increase from 1996 to 2005, a new study showed, but medical experts said they remain concerned that too many youngsters are being unnecessarily exposed to the procedure's harmful radiation. Medical experts said that about one-third of kids who receive the scans likely are exposed unnecessarily to radiation from the equipment. Ionizing radiation from computed tomography equipment, which uses X-rays to examine internal organs for bleeding, fractures or cancer, among other purposes, has been linked in previous studies to increased risk of cancer. Children appear particularly vulnerable because their organs are still developing and they have a longer period for cancer to form. In Monday's study, published in JAMA Pediatrics, researchers examined the rates and radiation dosages of CT scans used in children across seven large U.S. health-maintenance organizations between 1996 and 2011. The study examined data on the 152,000 to 370,000 children who got scans each year, for a total of 4.85 million child-years of observation. One child-year refers to data for one child over one year. For the 10 years up to 2005, use of scans doubled in kids younger than 5 and tripled in those aged 5 to 14. The rates then plateaued between 2006 and 2007 and began to decline between 2008 and 2010. “This is adding more to the body of knowledge of we're…overdoing CT scans in general and ionizing radiation in everyone, especially children,” said Eric Topol, director of the Scripps Translational Science Institute in La Jolla, Calif., who studies medical technologies and wasn't involved in the current study. The recent decrease may be connected in part to growing concerns about cancer risk from CT radiation, but probably also is related to a push to reduce unnecessary and expensive testing, said Diana Miglioretti, the first author on the study and a biostatistics professor at the University of California, Davis. Health-care spending of many types fell during the recession. However, there still likely is overuse of CT scans in children, Dr. Miglioretti said. For instance, medical evidence suggests that children with suspected appendicitis first should get an ultrasound, which doesn't use radiation, but many times they receive a CT scan initially. The researchers also used radiation-dosage information for CT scans, combined with prior studies on the amount of radiation associated with cancer, to project how many additional cancers might result from CT scans in childhood. They found that the highest risk was for abdomen scans, where one case of cancer could be expected in 300 to 400 girls and one in 700 to 800 boys who received such a scan.

Diabetes drug points the way to overcoming drug resistance in melanoma

Their studies, conducted in cell and animal models of melanoma, demonstrate that the combined therapy could destroy a subset of drug-resistant cells within a tumor. "We have found that the individual cells within melanoma tumors are not all identical, and tumors contain a sub-population of cells that are inherently drug resistant, which accounts for the fact that advanced melanoma tumors return no matter how much the tumor is depleted," said Meenhard Herlyn, D.V.M., D.Sc., professor and director of Wistar’s Melanoma Research Center. "We found that these slow-growing, drug-resistant cells are marked by a high rate of metabolism, which makes them susceptible to diabetes therapeutics." "Our findings suggest a simple strategy to kill metastatic melanoma — regardless of cell type within the tumor — by combining anticancer drugs with diabetes drug," Herlyn said. "The diabetes drug puts the brakes on the cells that would otherwise repopulate the tumor, thus allowing the anticancer drug to be more effective." In the Cancer Cell article, the researchers describe how various anticancer drugs, including cisplatin and the targeted therapy vemurafenib, which targets melanomas with the BRAF mutation, become more effective when co-delivered with phenformin. …

More doctors unclogging heart arteries through wrist

During artery unclogging procedures, doctors are increasingly accessing the heart through a vein in the wrist, rather than in the groin, Medical News Today reported. Artery unblocking surgeries, known as percutaneous coronary intervention (PCI) or coronary angioplasty, involve widening narrow areas of the artery by angioplasty or another similar method. Traditionally, doctors in the United States have accessed the heart through the femoral artery in the groin. However, a new study in the journal Circulation reveals that the number of wrist-entry operations, or radial PCIs, in the United States increased 13-fold between 2004 and 2007, Medical News Today reported. Based on data gathered from nearly 3 million procedures, researchers found that patients had a lower risk for bleeding complications during wrist-entry surgeries, compared to groin-entry surgeries. This is relevant because many patients undergoing artery unclogging surgeries are also on blood thinners, increasing their risk for bleeding complications post-surgery. As radial PCIs increase in popularity, researchers note that they are most effective for high-risk patients, including people 75 or older, women and patients with acute coronary syndrome (ACE), Medical News Today reported.

Screening fails to affect breast cancer mortality statistics, UK study finds

Researchers from the Department of Public Health at the University of Oxford sought evidence of a decline in population-based breast cancer mortality that could be attributed to the implementation of mammographic screening programmes. They concluded that population-based mortality statistics for England do not show a past benefit of breast cancer screening…

Diabetes-related deaths in New York City hit all-time high

Health officials say diabetes-related deaths in New York City have hit a record high, though the death rate is below the national average. The city Health Department said Monday that the disease was the underlying or a contributing cause of 5,695 deaths in 2011. That is about 160 more such deaths than in 2010 and 1,260 more than in 1990. That happened while the city's overall death rate hit an all-time low in 2010, when almost 8,000 fewer people died than in 2000. The city's diabetes death rate now amounts to 67 fatalities per 100,000 people. The federal Health and Human Services Department says the national rate was just over 73 diabetes-related deaths per 100,000 people in 2007. The city is launching a radio ad campaign about the risks of diabetes.source : http://www.foxnews.com/health/2013/06/11/diabetes-related-deaths-in-new-york-city-hit-all-time-high/

Be picky about fruit: Best ways to get your daily servings

It’s important to eat fruit throughout the year, and one of the perks of summer is there’s greater variety of fresh fruit to choose from.  According to the USDA’s Dietary Guidelines adults on a 2,000-calorie diet should eat about two cups of fruit per day, and for optimal health benefits it’s a good habit to eat a colorful mix.  But watch how you get your fruit because some commercial fruit products lose nutrients in processing and pack a lot of extra calories from added sugar. Fruit drinks Many commercial fruit juices are not 100 percent juice; some are so watered down that their taste comes from artificial flavors and sugar. To know what you are getting read the ingredients list on the nutrition label.  Juicing at home gives you more control over freshness and quality, but be sure to juice fruit with the skin or you could be throwing away some of the best nutrients. Case in point: a whole apple has 4g of fiber while apple juice pressed without the skin may have little to no fiber. Frozen fruit Did you know that frozen fruit may actually be more nutritious than the whole fruit at the supermarket?  That’s because whole fruit headed for the produce aisle is picked before it is fully ripe whereas frozen fruit is processed right in the field with fruit picked at its nutritional peak. Canned fruit Canned fruits, like frozen, are usually harvested at when they are fully ripe, but be sure to check how it has been prepared and packed. Some canned fruits swim in heavy sugar-based syrup that adds extra calories. Your best bet is to go with fruit canned in light syrup or better yet its own juice.  If your canned brand does contain added sugar you can rinse much of it off right before eating. Fruit safety Sometimes harmful bacteria can contaminate fresh fruits during harvesting. Avoid buying fruit that is bruised or visibly damaged, and it’s best to keep perishable fruits refrigerated at or below 40°F. And wash your fruit thoroughly even if you don’t intend to eat it with the skin.

Avoid hearing loss: Check the decibels before entering a room

An estimated 26 million Americans between the ages of 20 and 69 have some form of hearing loss due to exposure to loud noise at work or at play. That’s partly because our suburban and urban lifestyle has gotten louder, due to things like city traffic, a screeching subway, a football game, a loud bar or restaurant, or leaf blowers in the suburbs.  Research has also shown that the now ubiquitous practice of listening to music through earphones increases the risk of hearing loss. Aside from damaging hearing, loud noises are also associated with stress and symptoms of stress like hypertension and cardiovascular disease. As the noise level has increased, we’ve grown accustomed to the higher decibels, so it’s become difficult to know what is normal and what is too loud. According to the National Institutes of Health, long or repeated exposure to sounds at or above 85 decibels can cause hearing loss. The louder the sound, the shorter the time period before noise-induced hearing loss can occur. Regular exposure to more than one minute of 110 decibels or more risks permanent hearing loss. Less than 75 decibels is generally considered safe. Now to put that into perspective: Normal conversation is approximately 60 decibels, heavy city traffic can reach 85 decibels, stadium noise can roar to 120 decibels, a rock concert or symphony orchestra can reach 110 decibels, a snowmobile generates 100 decibels, and a movie hovers at 85 – but can have 100 decibel peaks. A good way of gauging high decibels is if you have to raise your voice to be heard by someone sitting or standing nearby; this is not uncommon in noisy restaurants, bars or at a concert. If the noise hurts your ears, it’s also a sign that it’s too loud. To get a more accurate reading on sound, you can download an app that can quickly measure decibels. “If you think something’s loud, you can pick up the phone and see just how loud it is,” said Dr. Annette Hurley, associate professor of communications disorders at Louisiana State University Health Sciences Center.   Walk into a restaurant, quickly test the decibels, and go somewhere else if it registers above 75. If you feel like being an advocate for all patrons, you can bring it to the attention of the restaurant owner, who may be able to lower the decibels simply by turning down the background music. If you’re going to a concert or other noisy venue, take earplugs to dampen the sound. Here are a few apps that Dr. Hurley recommends:  - dB Volume Meter - TooLoud? - deciBel It’s also a good idea to set maximum decibels on your personal listening device. If you’re trying to hear your music in a place that’s already noisy, it’s easy to inadvertently turn up the volume to damaging levels. Make sure it’s set below 85 decibels, recommended Dr. Hurley.Laurie Tarkan is an award-winning health journalist whose work appears in the New York Times, among other national magazines and websites.

Buffy star Sarah Michelle Gellar hopes to slay pertussis through vaccine awareness

While slaying vampires and saving the world may be her area of expertise, television and movie star Sarah Michelle Gellar said she was slightly overwhelmed when she had to tackle a subject she previously knew little about: children’s health care. Gellar is a mother to 3-year-old daughter Charlotte and son Rocky, who was born in September, and she said keeping them healthy has been one of the trickiest aspects of being a parent. “Someone told me when they start pre-school, they’ll be sick within the first six months,” said Gellar, who is famous for portraying Buffy the Vampire Slayer in the cult TV series of the same name.  “And sure enough, when my daughter started pre-school, she was sick for pretty much six months straight.  I thought that I would have a chair at the pediatrician’s office with my name on it, I had been there so much.” One daunting task for Gellar was delving into the world of childhood vaccinations and trying to understand the safest and most effective options for her kids.  Now having learned about the health dangers that face small children, Gellar has made it a priority to get her entire family vaccinated against pertussis – a serious illness, also known as whooping cough, that has been on the rise in the United States. While her family’s health is her chief concern, Gellar also wants others to follow her example.  Hoping to raise awareness about the importance of getting vaccinated, Gellar has teamed up with the Sounds of Pertussis Campaign, a crusade launched by Sanofi Pasteur and the March of Dimes that focuses on the dangers of pertussis and what parents can do to prevent their children from getting this potentially deadly disease. “I’m just like everyone else out there,” Gellar said.  “I’m a mom trying to keep my kids healthy, but I also have access to so much information that I can then go through it all and make it easier for people to understand.  You’re talking about an illness that doesn’t have to exist.  The only way to help fight against it is to get the vaccine, and that’s a simple way.” A serious respiratory illness, pertussis presents in infants and children like a common cold, with symptoms of a runny nose or congestion and sneezing.  But if left untreated, the disease can progress into severe coughing that forces air out of the lungs – causing pertussis sufferers to inhale with a large “whooping” sound.   According to the Centers for Disease Control and Prevention, America is experiencing one of the largest outbreaks of pertussis cases within the past 50 years, with more than 41,000 cases and 18 deaths reported in 2012.  Infants younger than 1 year of age are particularly vulnerable to the outbreak, since they do not begin receiving their own vaccinations until they are 2 months old, and they aren’t fully protected from the disease until they have received at least three doses.  This danger is compounded by the fact that infants with pertussis are often in need of hospitalization, and some can go on to develop life threatening pneumonia.   Gellar said this is why it is just as important for parents and teenagers to stay up-to-date on their vaccines in order to eliminate the possibility of passing pertussis on to small babies. “You look at the statistics, and they can track it back,” Gellar said.  “Eighty percent of the children who came down with it, they can track it back to a family member that brought it in, and 50 percent were the actual parents.  I know there’s nothing worse as a new parent than you thinking that you got your child sick…It’s a simple vaccination for an adult to get every five years, and that’s it.  It’s the only safe way to prevent the child from getting the disease.” To help families keep track of their necessary vaccinations, the Sounds of Pertussis campaign has created a Facebook application called The Breathing Room, which shows which individuals among a person’s friends and family have pledged to get vaccinated. As for the concerns that some parents have regarding the safety of vaccines, Gellar said it is important for people to do the necessary research and talk with the right people before making any judgments.  Gellar, along with many health care professionals, maintain there are minimal side effects when it comes to getting the shot. “I think there’s a lot of misinformation out there about vaccines,” Gellar said.  “People are scared, and I think that if you can bring (information) in a way that people understand the importance, and how simple it actually is, I think people will be more prone to do it.” To learn more about getting vaccinated against pertussis, visit the Sounds of Pertussis website and the campaign’s Facebook page.source : http://www.foxnews.com/health/2013/06/11/buffy-star-sarah-michelle-gellar-hopes-to-slay-pertussis-through-vaccine/

6 sex supplements contain hidden drugs, FDA warns

The Food and Drug Administration is cracking down on sex supplements again, warning the public on Monday about six products that were found to contain hidden drugs. The names of the tainted products are: Reload, Get It Up, Super Cheetah, Cave Diver, Nights to Remember and X Zen Platinum. All of the products are marketed for sexual enhancement, and sold on various websites and in some retail stores, the FDA said. All of the products were found to contain the drug sildenafil (sold under the brand name Viagra), and one was found to contain tadalafil (brand name Cialis). Sildenafil and tadalafil are prescription drugs used to treat erectile dysfunction. Sex supplements are not allowed to contain prescription drugs, and the drugs are not included on the products' labels. Undeclared drugs in supplements are dangerous because consumers ingest these drugs without being told about their risks. Sildenafil and tadalafil can cause adverse reactions, including dangerously low blood pressure, if taken along with other prescription drugs that contain nitrates, the FDA says. (Some drugs prescribed to treat chest pain and heart disease contain nitrates.) Consumers who take the products listed in today's warnings should stop using them immediately, and throw them away, the FDA says. Last month, the FDA recalled two sex supplements, called Vicerex and Black Ant, because the products contained sildenafil and tadalafil. Earlier this year, the FDA warned consumers that several other sexual enhancement supplements contained undeclared drugs. Because the FDA is unable to test and identify all tainted sexual enhancement products, consumers should exercise caution before buying any products in this category, the agency said.

10 signs you may have obsessive-compulsive disorder

Hooked on hand sanitizer? Closet organized to a T? Quirks like this can usually be chalked up to personality or preference, but in some cases they may point to a more serious issue: obsessive-compulsive disorder (OCD), a condition marked by obsessive thoughts and compulsions that affects about 1 percent of U.S. adults. How can you tell if OCD tendencies are symptoms that require professional help? There's no easy test, as it's usually a matter of degree, said Jeff Szymanski, executive director of the International OCD Foundation, a Boston-based advocacy organization. Still, there are certain patterns that may indicate the full-blown disorder. Here are 10 of the most common. Hand-washing Compulsive hand-washing or hand sanitizer use is so prevalent in OCD that “washers” has become a widely accepted category of OCD patient. The urge commonly stems from a fear of germs (the most common obsession seen in OCD), but it also can be rooted in fears of making others sick or of being impure or immoral. When to seek help: If you think about germs even after washing your hands, worry that you're not scrubbing well enough, or have irrational fears about disease (such as getting HIV from a shopping cart), it could be a sign that your hand-washing is compulsive, Szymanski said. Elaborate hand-washing routines—needing to wash five times and get soap under each nail, for example—are another warning sign. Health.com: Do You Have an Anxiety Disorder…
