Health Alert from NewsMax.com Headlines (Scroll down for complete stories): Study Doubts Melanoma is Epidemic Job Occupations Linked to Alzheimer's, Parkinson's Researchers Looking at Alzheimer's Vaccine Study Links Painkillers, High Blood Pressure 'Healthy' Vegetable Oils Are Usually Dangerous 1. Study Doubts Melanoma is Epidemic Belief that there is an epidemic of deadly melanoma, now being diagnosed at twice the rate it was in 1986 and increasing faster than any other form of cancer, has been challenged by a study published in the current issue of The British Medical Journal. According to the New York Times, Dr. H. Gilbert Welch of the Department of Veterans Affairs in White River Junction, Vt., and Dartmouth Medical School and his two colleagues, Dr. Woloshin and Dr. M. Schwartz, analyzed melanoma's changing incidence and death rate over time. Using Medicare data to track the swift rise in melanoma cases since 1986 and data compiled by the National Cancer Institute to track the death rate and the number of people with early and late-stage disease the researchers learned that since 1986, skin biopsies have risen by 250 percent, a figure nearly the same as the rise in the incidence of early stage melanoma. They discovered, however, that there was no change in the death rate from the lethal form of skin cancer. They also discovered that the incidence of advanced melanoma disease also did not change. Dr. Welch and his colleagues insist that if there was really an epidemic of melanoma - if for example, something in the environment was causing people to get the skin cancer, scientists should see increases in cancers at all stages. According to the Times, this is what happened with lung cancer caused by smoking, and with other cancers caused by toxic substances. The fact, however, that the increase was seen only in very early stage disease was a tip-off that the epidemic might be less than it appears to be, Dr. Welch explained. This, he says, leads to a difficult question. The point of screening for melanoma is to reduce the death toll from the cancer, yet if screening has not altered the number of patients with advanced disease or lowered the death rate, what is its benefit? " That's the million dollar question, " Dr. Welch said. " It certainly raises questions about whether we're doing any good. " He and his colleagues added, however, that people who notice suspicious moles or spots should not hesitate to see a doctor. But skin cancer screening, they said, is directed at healthy people who have no reason to suspect that anything is wrong. While admitting that more and more people are having skin biopsies, Dr. Darrell Rigel, a dermatologist in New York, said he questioned Dr. Welch's conclusion that the biopsies were leading to excessive diagnoses of melanoma. " I would say the inverse is more likely, " Dr. Rigel said. " There are more melanomas and therefore more biopsies. " At the American Cancer Society, Dr. Len Lichtenfeld, an oncologist, told the Times his group reviewed the same data as Dr. Welch and came to a different conclusion. Screening, he said, appears to be saving lives. He cited a trend in the data indicating that the death rate from the disease rose slightly year by year until about a decade ago. That, he told the Times, is consistent with an increase in serious cases of melanoma. Now, he said, " there has been a suggestion in the data that the death rates in the Medicare age group are going down, " an effect that would be expected if screening was working, adding that " We agree that some of the melanomas are biologically indolent, but we also feel that when we look at the trend in the data and the suggestion of decreased mortality that there has been a benefit from increased surveillance for the disease. " The cancer society, countered Dr. Welch, was " taking tiny, tiny differences " in death rates from year to year and " putting a huge microscope on it. " In fact, he said, the death rate has been basically flat since 1986, although it bounces around slightly from year to year as a result of statistical fluctuations. " We don't disagree about the data, " Dr. Welch added. " We disagree about the interpretation. We are not arguing that there is zero change in disease burden. We are arguing that most of the newly diagnosed cases are the result of increased screening. " The Times recalled that two dermatologists, Dr. Swerlick and Dr. Suephy Chen of Emory University and the Atlanta Veterans Affairs Medical Center, wrote in a 1997 article that while some people might be saved by screening, there also are risks from a melanoma diagnosis. " After a patient has received the diagnosis of melanoma, obtaining insurance can be extremely difficult, " they wrote. " The diagnosis of melanoma also results in heightened scrutiny of all first-degree relatives and family members of the patient, and if increased surveillance leads to increased diagnosis, this process may also put them at risk for the diagnosis of melanoma. " For his part, Dr. Welch says that early detection " is a double-edged sword and people need to remember that. " A few people might be saved because a cancer is found early, he said, but many, many more will be thrown into the medical mill when there is nothing wrong with them. " People should realize that is the price we pay for screening, " Dr. Welch said, and although screening is widely promoted, " we ought to know whether it helps.

Job Occupations Linked to Alzheimer's, Parkinson's Reuters reported this week that a wide range of occupations, from farming to teaching, may be potential risk factors for degenerative brain diseases, such as Alzheimer's and Parkinson's disease, research findings suggest. In a study of more than 2.6 million U.S. death records, researchers found that a variety of jobs were associated with an increased risk of death from several forms of brain degeneration, namely Alzheimer's and Parkinson's disease, early-onset dementia and motor neuron disease. Many of the associations had been seen in earlier research and could potentially be explained by on-the-job exposures to the chemicals that farmers, welders and hairdressers routinely use or inhale. Other findings, however, such as the elevated disease risks among teachers, clergy and bank tellers, are not easily explained, according to the researchers, led by M. Park of the National Institute for Occupational Safety and Health, Cincinnati, Ohio. In their analysis, Park and his colleagues found that the bank tellers, clergy, aircraft mechanics and hairdressers had highest odds of dying from Alzheimer's disease. For Parkinson's disease, the highest risks were among biological scientists, teachers, clergy members and other religious workers. The risk of death from presenile dementia - a form of dementia that arises before the age of 65 - was greatest among dentists, graders and sorters in industries other than agriculture and, again, clergy. Dr. Blaylock: You Can Prevent Brain Diseases The connection between chemicals and brain disease is not new for readers of The Blaylock Wellness Report, edited by Blaylock, M.D. Dr. Blaylock is a renowned neurosurgeon and nutritionist, and has warned of toxic substances causing an epidemic of brain diseases like Alzheimer's and Parkinson's. In a recent report, " Save Your Brain: Protect Yourself from the Ravages of Alzheimer's and Other Diseases, " Dr. Blaylock says when brain cells are weakened, either by disease or a lifetime of free-radical damage, they become much more vulnerable to injury by toxins of various types. It is for this reason that you must avoid further injury by avoiding known brain toxins. Among these toxins: Avoid fluoride. Avoid MSG. Avoid pesticides. Avoid vaccinations. Avoid aluminum. Avoid mercury in fillings. For complete details on Dr. Blaylock's report Go Here Now 3. Researchers Looking at Alzheimer's Vaccine Researchers are experimenting with a new nasal vaccine designed to reduce the brain plaque seen in victims of Alzheimer's disease. " It works in mice, " said Dr. Weiner. " I think the significance of the experiment is we've discovered a unique way of vaccination that may be of help for Alzheimer's. " Weiner, co-director of the Center for Neurologic Diseases at Boston's Brigham and Women's Hospital and Harvard Medical School, told WebMD: " We think it's very exciting. The next step is to see whether it's safe in humans and then we can test to see how efficacious it is. " The vaccine mixes an FDA-approved multiple sclerosis drug and another substance that helps stimulate immunity. The vaccine can be given as a nasal spray or as drops. It's designed to activate brain cells called microglia, which clean up a protein known as beta-amyloid that is found in the brain plaque seen in Alzheimer's disease. The researchers found that after the mice were treated with the vaccine, total beta-amyloid levels dropped 73 percent. Weiner added: " It's a totally unique type of vaccine from all the other vaccines that have been tried. " Editor's Note: Omega-3 can protect your brain from disease -- Go Here Now 4. Study Links Painkillers, High Blood Pressure Women taking daily amounts of non-aspirin painkillers - such as extra-strength Tylenol - should monitor their blood pressure, doctors say following a new study suggesting a link between the drugs and hypertension. " If you're taking these over-the-counter medications at high dosages on a regular basis, make sure that you report it to your doctor and you're checking your blood pressure, " said Dr. Christie Ballantyne, a cardiologist at the Methodist DeBakey Heart Center in Houston who had no role in the study. While many popular over-the-counter painkillers have been linked before to high blood pressure, acetaminophen, sold as Tylenol, has generally been considered relatively free of such risk. It is the only one that is not a non-steroidal anti-inflammatory drug or NSAID, a class of medications the federal government just required to carry stricter warning labels because of the risk for heart-related problems. Those include ibuprofen (sold as Advil and Motrin) and naproxen (sold as Aleve). Many had turned to those painkillers in the wake of problems with prescription drugs, such as Vioxx. However, the new study found that women taking Tylenol were about twice as likely to develop blood pressure problems. Risk also rose for women taking NSAIDS other than aspirin. The research found that aspirin still remains the safest medicine for pain relief. It has long been known to reduce the risk of cardiovascular problems and was not included in the government's requirement for stricter labels for NSAIDs. The study involved 5,123 women participating in the Nurses Health Study at Harvard Medical School and Brigham and Women's Hospital in Boston. None had had high blood pressure when it began. Results were published online Monday in the American Heart Association journal Hypertension. " It certainly sets the basis for more studies, " said Dr. Lawhorn, a cardiologist at St. Luke's Mid America Heart Institute in Kansas City. " Most of the time we think that things like acetaminophen are fairly safe drugs. " The study found that women ages 34-77 who took an average daily dose of more than 500 milligrams of acetaminophen - one extra-strength Tylenol - had about double the risk of developing high blood pressure within about three years. Women 51-77 who take more than 400 mg a day of NSAIDS - equal to say two ibuprofen - had a 78 percent increased risk of developing high blood pressure over those who didn't take the drug. Those ages 34-53 had a 60 percent risk increase. " We are by no means suggesting that women with chronic pain conditions not receive treatment for their pain, " lead author Dr. Forman, of Harvard Medical School and associate physician at Brigham and Women's Hospital in Boston, said in an e-mail. " By pointing out risks associated with these drugs, more informed choices can be made by women and their clinicians. " Previous research linking these drugs to blood pressure problems did not look at dose. The results in this study held up even when researchers excluded women who were taking pills for headaches, something that could itself be a result of very high blood pressure, said Dr. Curhan, another study author also of Harvard Medical School. As for why aspirin didn't raise risk, it might be because " aspirin has a different effect on blood vessels than NSAIDS and acetaminophen have, " said Dr. , dean of the school of medicine at University of Mississippi Medical Center in . © 2005 The Associated Press Editor's Note: Blood pressure medications have serious side effects.

'Healthy' Vegetable Oils Are Usually Dangerous Atherosclerosis is the scientific name for the process responsible for hardening of the arteries - the condition that leads to heart attacks and strokes. Back in the 1930s, studies indicated that elevated levels of cholesterol might cause accumulations of crud in arteries, thus hardening them. Corn oil was used in these studies to dissolve the cholesterol so that the test animals could eat it, and today, corn oil is even promoted as a cholesterol-lowering oil. But the irony here is that polyunsaturated vegetable oils such as corn oil are easily oxidized and produce rancid oils, much like rancid milk. When oxidized, these oils trigger inflammation and create free radicals. Both free radicals and chronic inflammation have been shown to cause atherosclerosis! So remember, the chemical composition of polyunsaturated fats found in many vegetable oils oxidizes rapidly, causing inflammation and free radical production. Research today shows that these early researchers mistakenly assumed it was the cholesterol causing the problem when the corn oil itself was the real cause. In fact, only when cholesterol is oxidized does it have any relationship to atherosclerosis. When oxidized, cholesterol becomes highly irritating to tissues, including those making up the walls of blood vessels. So the " healthy " vegetable oils being touted - such as corn, soybean, safflower, sunflower and canola - are contributing to the oxidation of cholesterol.
