11/11/2004 GINA KOLATA New York Times People who take high doses of vitamin E to improve their health may not be getting any benefits and may, in fact, be slightly increasing their risks of dying earlier, researchers reported yesterday. The adverse effect was tiny, however, and some experts with no connections to the vitamin industry say they are not convinced it was demonstrated. It emerged only when the researchers pooled the results from 19 clinical trials involving 135,967 participants. That led them to conclude that there were 39 additional deaths per 10,000 people who were taking vitamin E doses exceeding 400 international units a day. The recommended daily amount of vitamin E is about 20 international units a day, and the dose in a multivitamin pill is about 30 units. People take much higher doses because they believe that at high doses the vitamin acts like a drug, protecting them from disease. The new study, by Dr. Edgar R. Miller III, an associate professor of medicine and epidemiology at Johns Hopkins University, will be published on Jan. 4 in The Annals of Internal Medicine. Dr. Miller presented the data at the American Heart Association meeting yesterday in New Orleans, and the journal is making the paper available free on its Web site, www.annals.org. The results, some nutrition experts said, were disconcerting because vitamin E is widely used by people who hope it will act as an antioxidant and prevent heart disease, cancer, Alzheimer's disease, and even the common cold.

11/11/2004 Washington, D.C. DONNA DE LA CRUZ newsday.com About 30,000 Americans each year contract oral cancer, and 8,000 of them will die, but people remain ignorant of a disease that can be cured if caught in the early stages, a University of Medicine & Dentistry of New Jersey official said Wednesday. "This is not a disease that strikes just old men anymore," said Arnold Rosenheck, assistant dean at UMDNJ's dental school, before he was to speak to health care professionals about oral cancer at the American Public Health Association's annual meeting here. Oral cancer can strike anyone, even people who don't smoke or drink, which are two of the risk factors, Rosenheck said, adding that his goal is to educate Americans and health care professionals on how to prevent the disease. Oral cancer once struck mainly men in their 60s, but the largest increase in cases now is seen in people under 40 years of age, and in women. The survival rate remains unchanged from 50 years ago - about 50 percent for someone diagnosed with the disease in its later stages. Women began developing oral cancer when smoking became chic, said Rosenheck, referring to the well-known Virginia Slims ad campaign, "You've Come a Long Way, Baby," that ran from 1968 to 1986. "As a result, women have taken their place alongside their male counterparts in developing the diseases that are prevalent to tobacco use," Rosenheck said. "And I think women are drinking more openly now, going out with the [...]

11/9/2004 Elizabeth Querna USNews.com Straight, white teeth signify not only good physical health but also high social class. A nice set of choppers makes you look more employable, giving new meaning to the phrase putting your money where your mouth is. But for those segments of population without access to healthcare, bad teeth have economic and physical consequences. A policy report from the Joint Center for Political and Economic Studies' Health Policy Institute in Washington, D.C. shows how the disparity in dental care hurts one group, African-American males. What the researchers wanted to know: How good is the dental health of African-American males, and what can be done to improve it? What they did: The authors pulled from numerous research studies showing differences in the dental care received by people of different races. Using studies published in the past decade, the authors examined dental care coverage, disease and tooth loss rates, percentage of black dentists, and dental visitations by African-American men. What they found: Fifty percent of black men have untreated dental decay as compared with 28 percent of white men; black men also have the highest rate of oral cancer of any demographic group, and the lowest survival rate. In Harlem, N.Y., 46 percent of African-American seniors were missing teeth, compared with 22 percent of Latinos. More than 9.5 billion African-American men, about 75 percent of the population, are without dental coverage, and are not usually eligible for Medicaid. Fewer than 25 percent of black men have visited a [...]

11/9/2004 Lidia Arcavi, MD; Neal L. Benowitz, MD Archives of Internal Medicine, Vol. 164 No. 20, November 8, 2004 Background: Infectious diseases may rival cancer, heart disease, and chronic lung disease as sources of morbidity and mortality from smoking. We reviewed mechanisms by which smoking increases the risk of infection and the epidemiology of smoking-related infection, and delineated implications of this increased risk of infection among cigarette smokers. Methods: The MEDLINE database was searched for articles on the mechanisms and epidemiology of smoking-related infectious diseases. English-language articles and selected cross-references were included. Results: Mechanisms by which smoking increases the risk of infections include structural changes in the respiratory tract and a decrease in immune response. Cigarette smoking is a substantial risk factor for important bacterial and viral infections. For example, smokers incur a 2- to 4-fold increased risk of invasive pneumococcal disease. Influenza risk is severalfold higher and is much more severe in smokers than nonsmokers. Perhaps the greatest public health impact of smoking on infection is the increased risk of tuberculosis, a particular problem in underdeveloped countries where smoking rates are increasing rapidly. Conclusions: The clinical implications of our findings include emphasizing the importance of smoking cessation as part of the therapeutic plan for people with serious infectious diseases or periodontitis, and individuals who have positive results of tuberculin skin tests. Controlling exposure to secondhand cigarette smoke in children is important to reduce the risks of meningococcal disease and otitis media, and in adults to reduce the risk of [...]

11/9/2004 Pia Huguenin, Karl T. Beer et al. Journal of Clinical Oncology, 10.1200/JCO.2004.12.193 Purpose: To determine whether the application of two courses of cisplatin simultaneously with hyperfractionated radiotherapy improves the outcome in locally advanced and/or node-positive nonmetastatic carcinomas of the head and neck, compared with hyperfractionated radiotherapy alone. Patients and Methods: From July 1994 to July 2000, 224 patients with squamous cell carcinomas of the head and neck (excluding nasopharynx and paranasal sinus) were randomly assigned to hyperfractionated radiotherapy (median dose, 74.4 Gy; 1.2 Gy twice daily) or the same radiotherapy combined with two cycles of concomitant cisplatin (20 mg/m2 on 5 days of weeks 1 and 5). The primary end point was time to any treatment failure; secondary end points were locoregional failure, metastatic relapse, overall survival, and late toxicity. Results: There was no difference in radiotherapy between both treatment arms (74.4 Gy in 44 days). The full cisplatin dose was applied in 93% and 71% of patients during the first and second treatment cycles, respectively. Acute toxicity was similar in both arms. Median time to any treatment failure was not significantly different between treatment arms (19 months for combined treatment and 16 months for radiotherapy only, respectively) and the failure-free rate at 2.5 years was 45% and 33%, respectively. Locoregional control and distant disease-free survival were significantly improved with cisplatin (log-rank test, P = .039 and .011, respectively). The difference in overall survival did not reach significance (log-rank test, P = .147). Late toxicity was comparable in both [...]

11/9/2004 Liz Szabo USA Today Supreme Court Chief Justice William Rehnquist's diagnosis of thyroid cancer, announced late last month, comes at an time when research in the malignancy — which experts say was stalled for many years — is suddenly taking off. In the past year or so, scientists have initiated at least 10 new studies of thyroid cancer, and a dozen more will soon be up and running, says Steven Sherman, an associate professor at M.D. Anderson Cancer Center in Houston. "There's been an explosion," Sherman says. "Before that, there was almost nothing." Thyroid cancer research has suffered partly because its most common variety is usually curable, making the disease seem less threatening. Yet the most aggressive form of thyroid cancer, anaplastic carcinoma, is one of the most lethal of all tumors. Anaplastic cancers afflict so few people — just a few hundred a year — that experts long doubted that it was possible to even start clinical trials, says Manisha Shah, a thyroid cancer specialist at Ohio State University Comprehensive Cancer Center. Recent research has been sparked by the discovery of genetic mutations involved in thyroid tumors, as well as progress in the growing field of "targeted" cancer therapies that affect the tumors but not the surrounding, healthy tissue. Last year, a team of scientists at Johns Hopkins University School of Medicine discovered a genetic mutation that is present in most papillary thyroid cancers, the most common sort. Earlier this year, the same team showed that the mutation [...]

11/9/2004 Michael Flynn Ashville Citizen-Times Paul Turner directs the North Carolina Spit Tobacco Education Program, which seeks to reduce the rate of spit tobacco use among the state's middle and high school students and to make sure people are aware that smokeless tobacco is not harmless. Nationally, spit tobacco use among high school boys is 10.8 percent, but North Carolina`s rate is 17.6 percent and in Western North Carolina the rate is more than 35 percent. The N.C. Health and Wellness Trust Fund has awarded the program $304,500 grant, which is administered by the Haywood County Health Department. Before joining the program, Turner retired after a lengthy career with the Centers for Disease Control and Prevention, including serving as Deputy Director of the Division of Oral Health. Turner has also served as director of Oral Health America's National Spit Tobacco Education Program. Question: What are the health risks of using spit tobacco? Answer: The risks include nicotine addiction and dependence, periodontal disease, tooth loss, increased heart rate and high blood pressure, heart disease and stroke, decreased stamina and endurance, delayed wound healing and gastric problems such as stomach problems and ulcers. In some cases spit tobacco use can result in oral cancer and death. Spit tobacco use is certainly not a safe alternative to smoking. Q: Why are the use rates higher in WNC than the rest of the state and country? A: It is part of our heritage. We are basically a rural environment with a lot of wide-open [...]

11/9/2004 WILMINGTON, Mass Business Wire DUSA Pharmaceuticals, Inc. today announced the signing of a second clinical trial agreement with the National Cancer Institute (NCI), Division of Cancer Prevention (DCP). The new agreement covers the clinical development of Levulan(R) photodynamic therapy (PDT) for the treatment of oral cavity dysplasia. It follows a similar agreement dated September 27, 2004, covering the treatment of high-grade dysplasia (HGD) within Barrett's Esophagus (BE). Levulan is DUSA's brand of aminolevulinic acid, or ALA. DUSA and the NCI DCP will be working together to prepare an overall clinical development plan for Levulan PDT in oral cavity dysplasia, starting with a Phase I/II study and continuing through Phase III studies if appropriate. The immediate plan is for the NCI DCP to solicit clinical protocols from its extramural expert clinical investigator consortium, after which time DUSA and the NCI DCP will finalize the clinical trial design. The NCI DCP will use its resources to file its own IND. DUSA will provide Levulan, device(s) and the necessary training for the investigators involved in the studies. DUSA will maintain full ownership of its existing intellectual property and, subject to successful Phase II and III clinical trial results, intends to seek FDA approval in due course. Oral Cancer and Dysplasia Approximately 30,000 Americans will be diagnosed with oral cancer this year, and another 12,500 will be diagnosed with cancer of the larynx, or voice box. Risk factors include tobacco use and alcohol consumption. Some types of pre-malignancy, such as leukoplakia (visible as [...]

11/9/2004 M Gorsky, JB Epstein, C Oakley, ND Le, J Hay, and P Stevenson-Moore Oral Surg Oral Med Oral Pathol Oral Radiol Endod, November 1, 2004 Objective: Oral cancer is primarily a disease of epithelial origin. The tongue is the most common site of oral cancer. Oropharyngeal cancer accounts for approximately 2% of all cancer deaths. The purpose of this study was to analyze a case series of patients with tongue cancer.Study design The medical records of 322 consecutive patients diagnosed with squamous cell carcinoma (SCC) of the tongue treated from 1979-1994 were reviewed. Results: Patients had a mean age of 61.1 years and a 1.5:1 male to female ratio. Approximately, half of the cancers were diagnosed at an advanced stage and most involved the base of the tongue. The majority of oral tongue tumors were diagnosed at an early stage and had more well-differentiated cell types than those of the base of the tongue. Localized discomfort was the most common complaint (66.5%), present for up to 6 months in patients prior to diagnosis and were related to the oral tongue in 90% of cases. Symptoms associated with base of tongue lesions included neck masses, dysphagia, ear pain, and weight loss. Seventy-nine percent of the patients smoked, 58% consumed alcohol on a daily basis, and 43% consumed more than 4 alcoholic drinks daily. Primary radiotherapy was the treatment of 49.6% lesions, of which 57% were at an early stage at diagnosis. The mean overall survival was 3 years and 5 [...]

11/8/2004 Patricia Anstett Charleston Gazette Kenji Izumi enters a small sterile room at the University of Michigan Medical Center, scrubbed and covered head to toe in white plastic disposable garments. A research scientist, he's the caretaker for a collection of cells that will grow to millions in just two weeks. When he gets enough - he needs a supply the size of a quarter - the cells will be harvested as mouth grafts for surgical treatment of oral cancers and periodontal disease. Eventually, the product could be used for other skull and facial problems. Synthetically grown skin grafts are common in medicine. Grown from human skin cells, the grafts have been used for years to treat burns by providing a continuous, vital supply of tissue for thousands of patients who need them. But oral surgeons found problems using such grafts in the mouth to repair wounds after surgery for oral and throat cancers and periodontal disease. Skin grafts are rigid, don't always last long and some - heaven forbid - grow hair like real skin does, says Dr. Stephen Feinberg, professor and associate chairman of research at U-M's section of Oral & Maxillofacial Surgery, in the Department of Surgery. The grafts the U-M team are working on do not grow hair because the cells come from inside a person's mouth. In August, Feinberg's U-M team began clinical studies with EVPOME, the oral mucosal tissue product for which the team has a pending patent application. The product is made from cells [...]
