Dr. Rebecca Sokol – Study links BPA in Plastics to Male Sexual Dysfunction

What’s up with erectile dysfunction and Bisphenol-A? A study funded by the federal government and released on Wednesday addressed this question. Apparently Bisphenol-A, a controversial chemical found in hard, clear plastic used in everything from baby bottles to food packaging, is one of the causes of erectile dysfunction and other sexual problems in men.

According to CNN Health, this is one of the first studies to examine the impact of BPA on the reproductive system of human males and supports findings previously reported only in animal research. The Washington Post reports that government agencies had already been questioning the safety of BPA, a compound that is found in thousands of consumer products and is detected in the urine of 93 percent of the U.S. population.

“This is a very compelling study,” states Dr. Rebecca Sokol, the director of the andrology program at the University of Southern California’s Keck School of Medicine. “It’s not cause and effect, but when you have the kind of ambient air quality assessment that they made, it comes pretty close to cause and effect.”

According to Vitals.com, Dr. Sokol received her medical degree and specialty training at the University of California.  Because of her prolific research contribution on the subject, she is considered one of America’s Leading Experts on Male Infertility.

De-Kun Li, a scientist at the Kaiser Foundation Research Institute who conducted the study, focused on 634 male workers at four factories in China. They were exposed to 50 times more BPA than what an average U.S. man faces.

After five years, their sexual health was compared with that of male workers in other Chinese factories where BPA was not present. Workers that were exposed to large amounts of BPA reported low sex drive, had four times more erectile dysfunction and were seven times more likely to have difficulty with ejaculation then the non-exposed group.

Representatives of the chemical industry feel the study has little meaning for consumers. They believe the study presents interesting information, but has little relevance since the average consumer is exposed to trace levels of BPA.

Last year the FDA’s scientific advisory board was critical of the agency for ignoring more then 100 academic and government studies that showed negative health effects of BPA. Obama’s administration and the FDA are now taking a closer look and a review is expected by the end of the month.

Dr. Sokol believes that the study did have some weaknesses. It was relatively small for an epidemiological study and the rate of erectile difficulty among the BPA workers was still relatively small, a little more than 15 percent.

“The BPA levels measured in the study were extraordinarily high and they may have little or no relevance to somebody drinking water out of a bottle. But we need to be prudent and cautious about whether this chemical actually is impacting reproduction. People have to stop and say, ‘Whoa, now we’re starting to get data in animals that are manifested in humans.’ ”

Dr. Matthew Lewin - Multitasking Wastes Time and Risks Your Life

The Boston Globe reports that as we cram more tasks into less time, frustration grows, quality of work drops and our brains take a hit. In trying to be more efficient, we could be actually wasting time or even worse endangering our lives.

Drivers who split their attention between the road and texting or e-mailing colleagues are the most dangerous multi-taskers. Distracted drivers account for nearly 80 percent of crashes, according to the National Highway Traffic Safety Administration.

Flying 37,000 feet over Denver, Colorado is definitely not a place to get distracted. But last week Timothy Cheney and Richard Cole were two airline pilots whose attention was elsewhere when they overshot their destination by 150 miles. Instead of monitoring the plane or responding to calls from traffic control, they were on their laptops discussing their new work schedules.

Just walking in the street can be hazardous, if all of your attention is on reading a text message. Dr. Matthew Lewin, an emergency physician at the University of California, was a first- hand witness of such an unfortunate incident.

“In March we were driving and saw a woman in her 20’s step off the road and get struck square by a pickup truck. You could tell she saw the truck at the last moment, because her cell phone dropped right where she was struck just off the curb, and she was thrown about 20 or 30 feet. It was horrifying.”

According to Vitals.com, Dr. Matthew Robert Lewin received his medical degree at the University of Texas and completed his specialty training at UCSF-Fresno Medical Program.

Researchers are discovering that constantly switching tasks may be a lot less effective than it might appear. According to a 2001 study, people who toggle between tasks lose valuable time in the transitions. The brain must refocus each time it switches activities, which can be as little as tenths of a second but add up over the course of the day.

Sometimes multitasking is inevitable. Here are some of the suggestions listed in the Boston Globe on how to ease the strain on the brain.

  • Combine easy and difficult tasks, like sitting in the waiting room of a doctor’s office and answering emails.
  • The fewer switches the better. If you’re working on an important project, check your emails every half hour instead of every ten minutes.
  • Practice paying attention. Constant multi-tasking may cause the brain to forget how to concentrate intensely on one activity, which is also a useful skill.

Most importantly, save phone calls or other distracting activities for when you and your car are in park.

Merck Creates Gender Equality - Gardasil Prevents Cervical Cancer and Male Genital Warts

Merck announced on Friday that U.S. regulators cleared its vaccine Gardasil to prevent genital warts in boys, a new use for a product already approved to prevent cervical cancer in women. The vaccine protects against a sexually transmitted infection called human Papillomavirus, or HPV, which infects approximately 20 million Americans.

“A fair number of people can carry the HPV virus and show no symptoms, so it can easily be passed on without people even knowing it. This vaccine will help cut down on the transmission of the virus,” said Dr. Paul Shin a urologist at George Washington University Hospital in Washington.

According to Vitals.com, Dr. Shin received his medical degree and completed his specialty training at the University of Virginia.

In a Merck-funded study released last year, researchers gave 4,065 males aged 9-26 the vaccine or a placebo. After 30 months three men getting Gardasil developed genital wart and none had precancerous growths compared with 28 cases of warts and three precancerous growths in the placebo group.  Studies have found it safe and nearly 100 percent effective in preventing the cancers targeted by the vaccine.

Expanding the shot’s use could add as much as 200 million in annual sales. Gardasil generated revenue of 1.4 billion last year, having already sold 50 million doses worldwide. Sales had been slowing amid questions about the longevity of the vaccine’s effect and it’s price tag of almost 400 dollars. Merck plans to expand a patient rebate and dose replacement program to help cover the cost of the vaccine for 19-26 years old men without health insurance and those with private insurance but no coverage.

Theoretically the approval could double the market for Merck. But analysts do not expect the vaccine to be widely used by boys, because the public health benefit might be outweighed by the expenses. A study by researchers from Harvard School of Public Health found that using the vaccine for girls was well within being a good value, but when boys were added to the equation the benefits did not outweigh the costs.

Certain doctors disagree with this result, believing that if it’s cost effective to vaccinate girls against cervical cancer it would be cost effective to vaccinate boys to prevent oropharyngeal, pineal and anal cancer.  They especially feel this way when they see their patients suffering from treatment and others dying of these diseases.

Aspirin stems from willow tree bark, blood thinner Warfarin comes from sweet clovers, Captopril used for blood pressure comes from venom of a viper and now heart failure patients can benefit from the hormones of a green mamba snake.

Dr. John Burnett Jr. of Mayo Clinic in Rochester, MN, has concocted an intravenous drug medication that is now being tested in clinical trials and requires more research until 2010 to produce concrete results.  Potentially, the venom medication can save the million annual patient hospitalizations suffering from heart failure, which is one of the leading causes of death among the elder generations. 

Dr. Burnett established that “a hormone found in the African tree snake’s venom which helps widen blood vessels to deliver its poison faster, reducing high blood pressure in the process. The hormone also appears to boost kidney function, researchers say, unlike other treatments which place excessive strain on the kidneys and often cause heart patients to be re-admitted with kidney failure.”

A component of the hormone’s structure, they believed, indicated it would provide more support to the kidneys than the human body’s natural natriuretic peptides, boosting its ability to filter out salt and water. In animal studies, the drug was especially effective in reducing salt in the body.

According to Vitals.com, Dr. John Burnett is an internist with a sub-specialty in Cardiovascular Disease. He received his medical degree in Loyola University Stritch School of Medicine and finished his residency at Mayo Medical School.

Dr. Richard Podell: Chronic Fatigue Syndrome, or the Yuppie Flu, Is Legit

Dr. Richard Podell

Tell a friend you’re suffering from Chronic Fatigue Syndrome (CFS) and they’ll cluck in sympathy. But a mind reader would hear “Huh? What a hypochondriac!”

CFS is often dismissed as the “yuppie flu” and thought of as a mental not physical ailment.  Patients are often labeled as neurotic or depressed. Those who suffer from the ailment find the word “syndrome” offensive, which implies that it is not a real disease.

Not so. According to the cover of the New York Times Science Section, a study published last week in the Journal of Science reports that many patients who have the syndrome are infected with a recently discovered virus. The link has intrigued scientists and is seen as vindication by some patients and inspired hope for a treatment.

Dr. Richard Podell, a well-known Chronic Fatigue Syndrome specialist describes CFS as a condition in which mild physical or mental exertion induces severe fatigue and increased activity will typically cause symptoms to worsen.

According to Vitals.com, Podell received his medical degree at Harvard University and completed a specialty residency at Mt. Sinai Medical Center.

CFS has long been a medical mystery and the subject of debate, sometimes bitter, among doctors, researchers and patients. This syndrome affects at least one million Americans, causing extreme fatigue, muscle and joint pain as well as sleep problems, difficulty concentrating and other symptoms that sometimes last for years. Its cause is unknown and there is no effective treatment.

Annette and Harvey Whittemore long believed Chronic Fatigue Syndrome was an infectious disease, but scientists rejected the idea. The Whittemores were extremely frustrated with the lack of progress in the scientific community, especially since their 31 year old daughter suffered from this syndrome for over twenty years. They decided if a place was created to find the answers a treatment would be found more quickly.  In 2004 they spent several million dollars to set up an institute at the University of Nevada, hiring Dr. Judy Mikovits to head the research. Indeed a test is expected to become available within two weeks, which is one step closer to finding treatment.

What Mikovits and researchers from the National Cancer Institute and the Cleveland Clinic discovered was a strong link between Xenotropicmurine, or XMRV, and CFS. But although they established a link, it still hasn’t been proven whether or not XMRV is the actual cause of CFS.

XMRV is a retrovirus that’s from the same notorious family that causes AIDS and leukemia in people. It was first identified three years ago in a case of prostate cancer and later detected in about one quarter of biopsies from men with that disease.

Mikovits reported in Science that they’d found that 68 of 101 patients with chronic fatigue or 67% were infected with XMRV compared with only 3.7% of 218 healthy control patients. Further testing after the paper was written found nearly 98% of about 300 patients had the syndrome. Mikovits believes that the virus will eventually be found in every patient with chronic fatigue syndrome.

Their next step will be working out whether XMRV causes CFS or just grows particularly well in people who have it. If XMRV does turn out to contribute to CFS this could point to new treatments. 

Medical skeptics believe the study is exciting but inconclusive. They feel that more work needs be done to find out whether the new virus plays a role in CFS. Just detecting it in a patient doesn’t prove they suffered from a syndrome whose very existence they questioned

But doctors who specialize in CFS adamantly disagree and are frustrated that medical science still hasn’t caught up with this debilitating disease. This new discovery may have finally turned things around for this poorly understood illness that affects more than a million Americans.
