Mysterious Illness Forces Girl to Survive on a Diet of Mints

A U.K. teen eats only Tic Tac mints after a mysterious illness has left her unable to tolerate any other food, it is being reported.

According to a report on NewKerala.com, at one time, doctors believed Natalie Cooper, 17, suffered from bulimia because she would vomit after eating any type of solid food. But they soon realized the illness, which remains a mystery, was out of her control.

The girl, from Maidstone, Kent in the U.K., was diagnosed with the condition four years ago. She now receives all her nutrients from a specially formulated feed given to her in through a tube, it was reported.

She eats Tic Tacs, which do not make her vomit, to help her believe she isn’t hungry, the Mail reported.

“I went from Trebor Extra Strong Mints to Polos and ended up with Tic Tacs,” she is quoted as saying.

The feed tube has helped the teen go from a lean 70 pounds to a healthier 98 pounds, according to the report.

Baby shampoo study raises chemical concerns

Baby shampoos, lotions and powders may expose infants to chemicals that have been linked with possible reproductive problems, a small study suggests.

The chemicals, called phthalates, are found in many ordinary products including cosmetics, toys, vinyl flooring and medical supplies. They are used to stabilize fragrances and make plastics flexible.

In the study, they were found in elevated levels in the urine of babies who’d been recently shampooed, powdered or lotioned with baby products.

Phthalates (pronounced thowl-ates) are under attack by some environmental advocacy groups, but experts are uncertain what dangers, if any, they might pose. The federal government doesn’t limit their use, although California and some countries have restricted their use.

Animal studies have suggested that phthalates can cause reproductive birth defects and some activists believe they may cause reproductive problems in boys and early puberty in girls.

Rigorous scientific evidence in human studies is lacking. The current study offers no direct evidence that products the infants used contained phthalates, and no evidence that the chemicals in the babies’ urine caused any harm. Still, the results worried environmental groups that support restrictions on these chemicals.

HPV increasingly causes oral cancer in men

The sexually transmitted virus that causes cervical cancer in women is poised to become one of the leading causes of oral cancer in men, according to a new study.

The HPV virus now causes as many cancers of the upper throat as tobacco and alcohol, probably due both to an increase in oral sex and the decline in smoking, researchers say.

The only available vaccine against HPV, made by Merck & Co., is currently given only to girls and young women. But Merck plans this year to ask government permission to offer the shot to boys.

Experts say a primary reason for male vaccinations would be to prevent men from spreading the virus and help reduce the nearly 12,000 cases of cervical cancer diagnosed in U.S. women each year. But the new study should add to the argument that there may be a direct benefit for men, too.

“We need to start having a discussion about those cancers other than cervical cancer that may be affected in a positive way by the vaccine,” said study co-author Dr. Maura Gillison of Johns Hopkins University.

The study was published Friday in the Journal of Clinical Oncology.

Bluetooth-equipped prosthetic legs help double amputee walk again

As we’ve seen, there’s plenty of different solutions out there for controlling prosthetic limbs, but the artificial legs now helping Marine Lance Cpl. Joshua Bleill walk certainly have to rank up there with the most inventive, and they don’t even rely on brain control. Instead, the legs employ tried and true Bluetooth technology, which has previously been used to allow a single prothestic leg to mimic the individual’s other leg but, in this case, is being use to allow one prosthetic leg to mimic the other. To control them, Bleill simply applies force with his thigh muscles to get things moving or slow them down, with built-in motors in the legs allowing him to walk longer without getting tired. As you can see in the video available courtesy of CNN at the read link below, that setup appears to work remarkably well, and Bleill hopes he’ll soon get to the point where he needs just one cane before eventually ditching them altogether.

Pill prevents ovarian cancer for decades

Birth control pills can protect women against ovarian cancer for 30 years or longer after they stop taking them and have so far prevented 100,000 ovarian cancer deaths worldwide, British researchers said on Thursday.

The longer women stay on the pill, the lower their risk of developing the disease, which is more common after age 50, the researchers wrote in the journal Lancet. For example, women who take the pill for 15 years cut their risk in half, they said.

Worldwide the pill has already prevented 200,000 women from developing cancer of the ovary and has prevented 100,000 deaths from the disease, Valerie Beral of the University of Oxford and colleagues wrote in their report.

The findings are the strongest evidence yet of the benefits of the pill when it comes to ovarian cancer, and show the protection lasts far longer than people had thought, Beral said.

“When you are 60 it matters whether you took it for five years or 10 years in your twenties,” Beral said in a telephone interview. “The longer you took it, the better off you are when the risk of ovarian cancer is high.”

An estimated 300 million women have used the contraceptive pill since its introduction in the early 1960s. Hundreds of studies have looked at its safety, some suggesting benefits and others showing a raised risk of breast and cervical cancer.

Work-related stress can kill, study finds

Work really can kill you, according to a study on Wednesday providing the strongest evidence yet of how on-the-job stress raises the risk of heart disease by disrupting the body’s internal systems.

The findings from a long-running study involving more than 10,000 British civil servants also suggest stress-induced biological changes may play a more direct role than previously thought, said Tarani Chandola, an epidemiologist at University College London.

“This is the first large-scale population study looking at the effects of stress measured from everyday working life on heart disease,” said Chandola, who led the study. “One of the problems is people have been skeptical whether work stress really affects a person biologically.”

Heart disease is the world’s leading cause of death. It is caused by fatty deposits that harden and block arteries, high blood pressure which damages blood vessels, and other factors.

The researchers measured stress among the civil servants by asking questions about their job demands such as how much control they had at work, how often they took breaks, and how pressed for time they were during the day.

The team conducted seven surveys over a 12-year period and found chronically stressed workers — people determined to be under severe pressure in the first two of the surveys — had a 68 percent higher risk of developing heart disease.

The link was strongest among people under 50, Chandola said.

“This study adds to the evidence that the work stress-coronary heart disease association is causal in nature,” the researchers wrote in the European Heart Journal.

Behavior and biological changes likely explain why stress at work causes heart disease, Chandola said. For one, stressed workers eat unhealthy food, smoke, drink and skip exercise — all behaviors linked to heart disease.

In the study, stressed workers also had lowered heart rate variability — a sign of a poorly-functioning weak heart — and higher-than-normal levels of cortisol, a “stress” hormone that provides a burst of energy for a fight-or-flight response.

Study: Caffeine may boost miscarriage risk

New research out Monday may have expecting moms rethinking their drinking habits.

A new study has found that pregnant women who consumed more than 200 milligrams of caffeine a day, equivalent to about two cups of coffee, had twice the risk of miscarriage as the women who consumed no caffeine at all. The findings are published in Monday’s Journal of Obstetrics and Gynecology.

Previous studies have found similar results, but Dr. De-Kun Li, lead author and investigator with the Kaiser Permanente Division of Research, is quick to point out the significance of his findings. “We were able to address the issue of if the increase is really due to caffeine or due to women changing their drinking patterns. Other studies have reported the same results but had some biases in the research.”

HOW MUCH BUZZ?

Just how much is 200 milligrams of caffeine? We did the math for you.

 

 

• one to two cups of coffee (12 oz. serving)

   

• two to three cups of tea (12 oz. serving)

   

• one to three energy drinks

   

• about five cans of soda

 

Amounts are estimates; actual caffeine content may vary by brand

The Kaiser study looked at 1,063 women in the early stage of pregnancy. Among women who consumed no caffeine, the miscarriage rate was 12.5 percent. In comparison, 25.5 percent of women who consumed more than 200 mg of caffeine a day miscarried. Although there was an increased risk for women who consumed fewer than 200 mg of caffeine a day, the lead investigator says the increase is not statistically significant.

Researchers say it made no difference whether the caffeine came from coffee, soda, tea or hot chocolate.

Caffeine is dangerous during pregnancy, Li said, because it can cross through the placenta to the fetus and can be difficult for the fetus to metabolize the caffeine. Caffeine may influence cell development and decrease blood flow to the placenta, he added. If arteries are constricted it may restrict blood flow which can result in miscarriage.

FDA: No Cough, Cold Drugs for Tots

The FDA today urged parents and caregivers not to give over-the-counter (OTC) cough and cold medicines to children younger than 2 because of dangerous side effects. “We strongly recommend that over-the-counter cough and cold products should not be used in infants and young children under 2 years of age because serious and potentially life-threatening side effects can occur from use of these products,” Charles Ganley, MD, director of the FDA’s Office of Nonprescription Products, said at a news conference.

OTC cough and cold products include decongestants, expectorants, antihistamines, and antitussives (cough suppressants) for the treatment of colds.

An FDA news release states that rare, serious adverse events — including convulsions, rapid heart rates, decreased levels of consciousness, and death – have been reported with use of cough and cold products.

The FDA is still reviewing the use of cough and cold medicines in children aged 2-11.

Scientists Claim to Have Produced Embryo Clones of Two Men

Scientists say they have produced embryos that are clones of two men, a potential step toward developing scientifically valuable stem cells.

It’s the first documented demonstration that ordinary cells from an adult human can be used to make cloned embryos mature enough to produce stem cells, the researchers said. But because they haven’t produced those stem cells yet, experts reacted coolly.

Since other scientists had previously made a cloned human embryo, “I found it difficult to determine what was substantially new,” said Doug Melton of the Harvard Stem Cell Institute.

He said the “next big advance will be to create a human embryonic stem cell line” from cloned embryos. “This has yet to be achieved,” Melton said.

Korean scientist Hwang Woo-suk claimed a few years ago that he’d created such cell lines, but that turned out to be a fraud.

Dr. Samuel Wood, a co-author of the new paper and chief executive of Stemagen Corp. of La Jolla, California, said he and his colleagues are now attempting to produce stem cell lines from the embryos.

The work was published online Thursday by the journal Stem Cells.

Scientists say stem cells from cloned embryos could provide a valuable tool for studying diseases, screening drugs and, perhaps someday, creating transplant material to treat conditions like diabetes and Parkinson’s disease.

But critics raise objections. Some say the procedure amounts to creating a human life in a lab and then destroying it to harvest the stem cells. Others raise concerns about health risks and exploitation if large numbers of women are asked to provide eggs for widespread cloning.

Those objections are one reason that an alternative route to stem cells made headlines last November. Scientists reported a relatively simple way to turn skin cells directly into stem cells. This direct reprogramming carries a theoretical risk of cancer for the recipients of tissue from these cells, however, and many scientists have urged that work continue on the cloning technique as well.

The cloning approach involves inserting DNA from a person into an egg, and then growing the egg into an embryo about five days old before extracting the stem cells. At that stage, the embryo is a sphere of about 150 cells.

In the new work, researchers took skin cells from Wood and another volunteer and produced three embryos with DNA matching the men’s. Further DNA testing on one of these embryos strengthened the case that it was a clone, researchers said.

No more dodgeball? PE now about individuals

With music pumping in the background, the kids in Terry Wade’s physical education class are in constant motion, going from sit-ups to jumping jacks to curls with light weights.

After their 45-minute session, the sixth-graders who are sweating the most, or as Wade calls it, “burning butter,” get stickers.

“My main goal and emphasis is getting these kids up and moving,” said Wade, who teaches at Northrich Elementary in the Richardson school district in suburban Dallas. “It’s ’Can this kid do this for a lifetime?’ I don’t care how good they are. I care if they’re having fun.”

Instead of team sports, Wade and other physical education teachers across the country are focusing more on individual activities that students can incorporate into their lives long after their school days are over.

Experts say the shift also helps gym teachers include children who are struggling with their weight. With individual activities, overweight students can work at their own pace, and not be left on the sidelines. And they can take part in lower impact activities like weightlifting, yoga or martial arts.

“Now we organize our classes in such a way where no kids are sitting,” said Susan Henderson, coordinator for physical education and health for the Dallas-area Mesquite school district.

She said that even if the lesson is about a team sport like football, they focus on skills like passing the ball.

“Nobody is waiting their turn,” Henderson said.

Steve Jefferies, head of the department of health, human performance and nutrition at Central Washington University in Ellensburg, Wash., is a fan of treasure hunts and other activities that students can do without realizing they are getting exercise. That shifts the focus to finding things, not the half-mile walk to get there, he said.

Jefferies suggests teachers wear a weight belt to get an idea of what an overweight student experiences.

“You’ve got to find something that each individual person enjoys,” said Jefferies, who also runs a Web site to help physical education teachers keep up with the latest developments.
