Students hear ‘wake-up call’ about tobacco

Source: Star-Tribune Writer: ALLISON RUPP Gruen Von Behrens' story brought some middle-schoolers to tears. If it didn't bring tears, it at least had them asking questions and thinking about the negative effects of tobacco. During the question and answer part of Von Behrens' presentation, one girl's voice trembled as she asked, "How long does it take someone to die from tobacco?" Von Behrens doesn't care if he scares students. In fact, that's what he wants. "Some of the things may scare you," he said in the beginning. "If scaring you is what keeps you from using tobacco products, then I am going to scare the pants off you." Von Behrens didn't even need to open his mouth for some fear to set in. He has undergone 34 surgeries and hundreds of procedures to remove oral cancer from his mouth and repair what was left over. His face prominently shows what chewing tobacco can do. The 31-year-old lost all his teeth, most of his tongue and his jaw, although part of a leg bone was used to replace the jaw. Layers of skin from his thigh were used to try to rebuild his chin. Von Behrens began chewing tobacco at 13. Students and teachers called the presentation "powerful." "My parents don't smoke, do drugs or really drink alcohol so I always knew I didn't really want to do that stuff," said Levi Shade, an eighth-grader at Poison Spider School. "But now it's a sure thing -- I will never ever do it." Von [...]

Row erupts over oral cancer paper authorship

Source:The Australian Writer: Gay Healy AN international expert on oral cancer withdrew from joint authorship of a paper that drew a link between the disease and theListerine mouthwash made by his university laboratory's corporate sponsors, it has been claimed. The research paper's co-authors say Newell Johnson, whose Griffith University laboratory was funded by pharmaceutical firm Pfizer, Listerine's recent owner, decided not to put his name to the research paper, which made headlines across the world with its finding that alcohol-based mouthwashes were implicated in oral cancer. Professor Johnson says he was never an author. The claim about his involvement and withdrawal, made by Australian co-authors Michael McCullough of the University of Melbourne and Camile Farah of the University of Queensland, adds a new dimension to the controversy ignited by the paper, published in the Australian Dental Journal last December. In January UQ's head of dentistry Laurence Walsh came to the defence of mouthwashes, arguing they might prevent oral cancer, but later conceded that Listerine's present owner, Johnson & Johnson, had sponsored some of his workshops. The paper found the risk of oral cancer was increased by prolonged use of alcohol-based mouthwashes and highlighted six Listerine products. Professor McCullough said the research paper or literature review sprang from a 2007 meeting of the three researchers at a conference in Amsterdam. "After a session on the role of alcohol in oral cancer, we ended up deciding that we would formally write this article and review it between the three of us," hesaid. [...]

Dental Calamities That Can Truly Hurt

Source: New York Times Writer: Nicholas Bakalar DENTAL cavities are not good news, but when it comes to preventive oral health, they may be among the smaller problems. The advice is familiar: brush and floss regularly, use fluoride mouthwash, limit snacks and sweet drinks, visit the dentist twice a year. Good suggestions, even if not everyone follows them: by age 12, 50 percent of children have cavities. But there are two much more serious problems, common dental diseases that can lead not only to loss of teeth but also to loss of life: periodontal disease and oral cancer. Periodontal disease — a chronic bacterial infection of the gums that destroys the bone and tissues that hold the teeth — is the leading cause of tooth loss in adults. Some people are genetically susceptible, and the problem can be aggravated by smoking, taking certain medications, stress and other factors. Several studies have found that gum disease is associated with an increased risk for heart attack. “It isn’t nailed down yet,” said Dr. Martin J. Davis, professor of clinical dentistryat the College of Dental Medicine at Columbia, “but there seems to be a link between the inflammation of gums and the inflammatory markers of heart disease.” It may be that oral bacteria enter the bloodstream, attach to fatty plaques in the coronary arteries and cause clots to form. Or maybe inflammation itself increases plaque buildup. A 2007 study showed that periodontal disease increased the risk of heart disease in men by one third and doubled it in women, even [...]

Smokeless tobacco may not help smokers quit

Source: health.usnews.com Author: staff Cultural factors appear to influence whether smokeless tobacco can help smokers quit cigarettes, contends a new study. In Sweden, many smokers try to quit smoking by using snus, a form of moist, powdered tobacco that's placed under the lip. In Sweden, snus is more popular among male smokers, and Swedish men have higher smoking cessation rates than women. Some people have suggested that public health officials in the United States and other countries should promote smokeless tobacco as a way to help smokers quit cigarettes. However, University of California, San Diego, researchers examined data collected from more than 15,000 people in the United States and found that smokeless tobacco does not increase American smokers' quit rates. "With an ongoing tobacco control effort, men in the U.S. seem to be quitting smoking at higher rates than men in Sweden. And U.S. women are quitting at the same rate, unlike their counterparts in Sweden," study author Shu-Hong Zhu, a professor of family and preventive medicine in the UCSD School of Medicine, said in a university news release. The study found that: Among American men, less than 1 percent of current smokers switched to smokeless tobacco during the 12-month study. Only 1.7 percent of former smokers turned to smokeless tobacco. Men's quit rate for smokeless tobacco was three times higher than for cigarettes. Men were far more likely than women to use smokeless tobacco products, but smoking cessation rates were similar among men (11.7 percent) and women (12.4 percent). [...]

Visual Screening for Oral Cancer is Cost Effective in Low-Income Countries

Source: Carolina News Wire Writer: Lisa Bistreich, Patrick Gibbons RESEARCH TRIANGLE PARK, N.C. — Using visual inspection to screen for oral cancer is a cost-effective approach to earlier diagnosis in low- and middle-income countries, according to a study conducted by researchers at RTI International. The study, published in the Bulletin of the World Health Organization, looked at health care workers in Southern India, where oral cancer is a major health problem, and found that visual oral screening, particularly among high-risk individuals is cost-effective. "Our results show that screening for oral cancers by visual inspection is comparable or less expensive than the more widely accepted practice of screening for cervical cancers," said lead author Sujha Subramanian, a senior health economist at RTI. "We hope that the findings of this study will increase screening for oral cancers and help reduce the devastating impact of this cancer on families." More than 160,000 people participated in the study, and the researchers found that targeted screening of the high-risk group of alcohol and tobacco users is the most cost-effective approach. They determined that visual inspection for oral cancer targeted to high-risk people could be performed for under $6 per person over the course of a nine-year screening program. According to GLOBOCAN, the Indian subcontinent alone accounts for one-third of the world burden and oral cancer is the most common form of cancer and cancer-related death among men in India. Two-thirds of all deaths from oral cancers occur in low income countries. Worldwide, 270,000 new cases and 145,000 [...]

Risk of cerebrovascular events after neck and supraclavicular radiotherapy: a systematic review

Source: Radiother Oncol, January 24, 2009 Author: Apryl S Scott, Luke A Parr, and Peter A S Johnstone Objective: Although low dose radiation therapy (RT) has been used to prevent re-occlusion of coronary arteries, it may also precipitate vascular damage. Specifically, irradiation to the neck is related to subsequent vascular wall thickening and atherosclerotic plaque formation. Several investigators, reporting patients with varied disease processes and using different methods, have described an increased risk of cerebrovascular events (CVEs) after RT to the neck for head and neck cancer, breast cancer, or lymphoma. Our purpose is to determine the rate and risk of CVEs in patients after receiving radiation therapy to the neck. Methods: We performed a pooled analysis of the published data to document the cumulative risk of subsequent stroke after RT to the neck. An extensive MEDLINE and PUBMED search yielded five articles involving 6908 patients describing institutional series or cohort analyses comparing the frequency of CVE in irradiated versus non-irradiated patients. Results: Sixty-six CVEs were reported in 2567 patients after neck RT, whereas only 12 CVEs were documented in 4119 non-irradiated patients. Crude risk of CVEs after neck RT was 2.6%, and was 0.29% in non-irradiated patients. This odds ratio of 9.0 was statistically significant (95% CI 4.9, 16.7; p<0.0001). Data for supraclavicular RT were more difficult to analyze given differences in populations and reporting between the three studies, but it appears a significant risk is unlikely. Conclusions: Neck RT increases the likelihood of CVEs, but this risk must [...]

USC study finds that green tea blocks benefits of cancer drug

Source: news.biocompare.com Author: staff Contrary to popular assumptions about the health benefits of green tea, researchers at the University of Southern California (USC) have found that the widely used supplement renders a cancer drug used to treat multiple myeloma and mantle cell lymphoma completely ineffective in treating cancer. The study, which found that a component of green tea extract (GTE) called EGCG destroys any anticancer activity of the drug Velcade in tumor-bearing mice, will be published in a future print edition of the journal, Blood. It is now available online at the journal's pre-publication First Edition website. "Our finding that GTE or EGCG blocked the therapeutic action of Velcade was completely unexpected," says lead author Axel H. Schönthal, PhD, associate professor in the Department of Microbiology and Immunology at the Keck School of Medicine of USC. "Our hypothesis was that GTE or EGCG would enhance the anti-tumor effects of Velcade, and that a combination of GTE with Velcade (or EGCG with Velcade) would turn out to be a superior cancer treatment as compared to treatment with Velcade alone." Herbal remedies, including green tea, have become a popular remedy for cancer patients dealing with side effects of chemotherapy. However, these supplements are unregulated and, for most, their beneficial and/or detrimental effects have not been qualified through research. Using preclinical models and tumor-bearing mice, the researchers found that the unusually effective blockage of Velcade's therapeutic activity was based on the chemical interaction between molecules. The EGCG molecule and the Velcade molecule were [...]

Perceptronix reports clinical study underway to evaluate OralAdvance(TM) for early detection of oral cancer

Source: www.earthtimes.org Author: press release Perceptronix Medical Inc. announces that a clinical study of OralAdvance(TM), a test for the early detection of oral cancer, is now underway. The clinical study will assess the performance of OralAdvance(TM) compared to the gold standard biopsy and histology for its ability to differentiate between visually suspicious oral lesions with cancer or pre-cancer and visually suspicious benign oral lesions. "Unlike many other types of cancer, the incidence and mortality rates of oral cancer have not shown significant improvement over the past 30 years. By the time most oral cancers are diagnosed, they are already symptomatic late-stage disease. At Perceptronix we are dedicated to changing this paradigm towards early detection for better patient outcomes," says Dr. Bojana Turic, President and CEO of Perceptronix. Patients for the blinded study will be recruited from the BC Cancer Agency's Vancouver and Fraser Valley Centres. "We are pleased to be able to participate in the evaluation of the test in a clinical setting with technology that was developed in partnership with scientists at the BC Cancer Agency's Research Centre, and we are hopeful that the test will have a positive impact on the early detection of oral cancer," says Dr. Allan Hovan (Provincial Professional Practice Leader, Program in Oral Oncology/Dentistry, BC Cancer Agency). Currently, the death rate for oral cancer is higher than that of cervical cancer, Hodgkin's disease, cancer of the brain, liver, testes, kidney, or malignant melanoma. High death rate associated with oral cancer could be reduced significantly [...]
