B.C. detection test being used to catch oral cancer in early stages

Source: www.cbc.ca Author: staff Doctor says oral cancer is among the deadlier diseases yet rarely talked about. The Canadian Cancer Society estimates 4,400 people will be diagnosed with oral cancer this year. The deadly disease can often go undiagnosed because it is tough to screen for dormant symptoms. But now, researchers at the University of British Columbia (UBC) are developing a new test that will be able to detect oral cancer at a much earlier stage. Dr. Catherine Poh, an oral pathologist who also teaches dentistry at UBC, spoke with the Early Edition's Rick Cluff about the latest developments. What can you tell us about this new brushing test you're working on? We are a proposing a non-invasive approach to analyse genetic material collected from patients mouths using a simple brush. This can be done by a dentist or at a family doctor's office. This test would detect genetic change that happens in human genomes from the cells collected from the mouth. We have shown that it has prediction value for the risk for oral cancer development. How does your test compare to how oral cancer is detected right now? Right now the majority of oral cancer has been screened by dentists because many of the oral cancer [diagnosis] come with no pain or no symptoms. Through the dental regular checkups it can be detected early, otherwise patients come with a sore in their mouths that is essentially a delay in the diagnosis. What symptoms should people look out for? [...]

Study finds how T cells cause inflammation with oral candidiasis

Source: www.drbicuspid.com Author: Donna Domino, Features Editor Ohio dental researchers have found a method to study how T cells cause inflammation during oral candidiasis infections, according to a new study in the Journal of Visualized Experiments (February 18, 2015). The discovery could lead to new therapies or drugs that may improve the functioning of weakened immune systems. Pushpa Pandiyan, PhD, an assistant professor at Case Western Reserve School of Dental Medicine, and colleagues worked on mice to find a new way to model how T cells, the white blood cells critical for the body's immune system, cause inflammation. Pandiyan's previous work focused on isolating different types of oral T cells for study. In the latest study, the researchers injected T cells into genetically engineered immunodeficient mice to test how the cells function when fighting Candida albicans, a fungus found in about 60% of the population but controlled by a functioning immune system. The infection becomes a particular health problem for people with the HIV/AIDS infection, cancer patients with immune systems weakened by chemotherapy, or those born with no immune defenses. The researchers investigated how IL-17a (T helper 17, or Th17 cells, a type of T cells that secrete a cytokine) and T regulatory cells (Tregs) controlled the fungal infection and inflammation, respectively. "Although Th17 cells are required for antifungal immunity, uncontrolled Th17 cells have been implicated with such illnesses as multiple sclerosis, lupus, psoriasis, cancers, and irritable bowel disease," Pandiyan said in a statement. The immunodeficient mice were infected with [...]

Study links gum disease, HPV-status of head and neck cancer

Source: www.buffalo.edu/ubreporter Author: Sara R. Saldi Human Papilloma Virus (HPV), once almost exclusively associated with cancer of the cervix, is now linked to head and neck cancer. Furthermore, according to a new UB study just published in the Archives of Otolaryngology—Head & Neck Surgery, a JAMA publication, gum disease is associated with increased odds of tumors being HPV-positive. Primary investigator Mine Tezal, assistant professor of oral biology in the School of Dental Medicine, and a team of scientists from UB evaluated data from 124 patients diagnosed with primary head and neck squamous cell carcinoma (HNSCC) between 1999 and 2007. “The aim of the study was to test the presence of periodontitis, a persistent inflammatory process and HPV-status of HNSCC,” Tezal says. Of the 124 tumor samples Tezal and her team studied, 50 were positive for HPV-16 DNA and that subjects with HPV-positive tumors had a significantly higher severity of periodontitis when compared to subjects with HPV-negative tumors. According to the National Cancer Institute, there has been a steady increase in the prevalence of oropharyngeal cancers in the U.S. since 1973. This is despite the significant decline in tobacco use since 1965, a year after the U.S. Surgeon General issued the landmark Report on Smoking and Health. Tezal notes that this increase has mainly been attributed to oral HPV infection. Understanding the natural history of the oral HPV infection and targeting factors associated not only with its acquisition but also with its persistence, says Tezal, will lead to more effective strategies, [...]

Berry Nutrition

Source: www.foodproductdesign.com Author: Marie Spano, M.S., R.D., Contributing Editor Nutritionally speaking, good things come in sweet—and tart—little packages. Research is discovering berries pack a nutritional punch due to their vitamin, fiber and antioxidant content. Botanically speaking, berries are indehiscent fruits (they don’t need to be opened to release their seeds) that ripen through the ovary wall. However, any small, edible fruit with multiple seeds is typically considered a berry. In addition to lending flavor and brilliant colors to a wide variety of dishes, all berries are packed with an array of antioxidants, nutrients and potential health benefits. Berries that are especially antioxidant-rich include fresh crowberries, bilberries, black currants, wild strawberries, blackberries, blueberries, goji berries, sea buckthorn, blueberries and cranberries. However, the antioxidant content of berries varies based on the geographical growing condition. And, while fresh berries are an excellent source of antioxidants, total phenol content drops during processing. In fact, processed berry jams and syrup contain approximately half the antioxidant capacity of fresh berries, and juices show the greatest loss of anthocyanins and tannins due to the removal of seeds and skin (Nutrition Journal, 2010; 9:3; Journal of Agricultural and Food Chemistry, Jan 13, 2012). Botanical berries Shiny, scarlet-colored cranberries are rich in vitamin C, loaded with antioxidants, including flavonoids, and score higher in their ORAC score than many other fruits ("Oxygen Radical Absorbance Capacity (ORAC) of Selected Foods—2007", USDA ARS). Cranberries are perhaps best known for the role their juice plays in the prevention of urinary tract infections (UTI) [...]

Emerging indications: antioxidants for periodontal disease

Source: http://www.dentistryiq.com Author: Edward P. Allen, DDS, PhD Since approximately 10 to 15 percent of adults worldwide suffer from periodontitis at one time or another(1), oral health professionals are constantly challenged with treating patients for existing conditions and helping them prevent future occurrences. Root planing, scaling, and in severe cases, surgical intervention are part of the standard treatment for periodontitis, and antibiotics are used for infection control. However, in recent years, dental health professionals have honed in on the inflammation that accompanies periodontitis. Research shows that inflammation in the oral tissues—especially that associated with periodontitis—can be a factor in chronic illness such as heart and vascular disease, diabetes, arthritis, Alzheimer’s, pregnancy complications, and a growing list of other conditions. The real culprit with inflammation is oxidative stress, a disturbance in the balance of oxidants and antioxidants. Oxidative stress is the result of overproduction of free radicals, unstable molecules that attack tissue cells by “stealing” electrons from other molecules. Although infection is a major trigger for inflammation and oxidative stress, there are numerous other causes, such as poor diet, alcohol consumption and nicotine use or chemical pollutants. In oral tissues oxidative stress can result from dental procedures and from materials used for bleaching, composite fillings, implants, crowns, veneers, and so on. Antibiotics control the micro-organisms that contribute to periodontitis and other infection, but they do not necessarily address the free radicals and oxidative stress that accompany inflammation. Innate defense through natural salivary antibiotics and antioxidants The human body has an innate [...]

If teeth could talk…

Source: wsj.com Author: Melinda Beck The eyes may be the window to the soul, but the mouth provides an even better view of the body as a whole. Some of the earliest signs of diabetes, cancer, pregnancy, immune disorders, hormone imbalances and drug issues show up in the gums, teeth and tongue -- sometimes long before a patient knows anything is wrong. There is also growing evidence that oral health problems, particularly gum disease, can harm a patient's general health as well, raising the risk of diabetes, heart disease, stroke, pneumonia and pregnancy complications. "We have lots of data showing a direct correlation between inflammation in the mouth and inflammation in the body," said Anthony Iacopino, director of the International Centre for Oral-Systemic Health, which opened at the University of Manitoba Faculty of Dentistry in Canada in 2008. Recent studies also show that treating gum disease improves circulation, reduces inflammation and can even reduce the need for insulin in people with diabetes. Such findings are fueling a push for dentists to play a greater role in patients' overall health. Some 20 million Americans -- including six percent of children and nine percent of adults -- saw a dentist but not a doctor in 2008, according to a study in the American Journal of Public Health this month. "It's an opportunity to tell a patient, 'You know, I'm concerned. I think you really need to see a primary care provider,' so you are moving in the direction of better health," said [...]

CU Med School prof seeing red over wine benefit study

Source: www.aurorasentinel.com Author: Sara Castellanos There’s a reason Robert Sclafani always chooses red wine over white wine, and it’s not just because he thinks it tastes better. Sclafani, a professor of biochemistry and molecular genetics at the University of Colorado’s School of Medicine, prefers the darker of the two wines because of its health benefits. Red wine contains much more of a compound called resveratrol, found in the skin of grapes and also in peanuts and leeks. Sclafani and his colleagues are currently testing the effects of resveratrol on mice, and this month he received encouraging news from overseas that resveratrol can have health benefits for obese humans. “There are a number of studies in animals where you can take an animal like a mouse and give it cancer by treating it with carcinogens or manipulating the genes in mice so they’ll get cancer,” Sclafani said. “If you treat the animal with resveratrol, it blunts the effect; they either get less cancers, cancers never develop or they never go anywhere.” Here’s how it works: resveratrol causes damage to the DNA in cancer cells, he said. “We think that’s the Achilles heel,” he said. The compound has been known to have positive effects for more than a decade, but on Nov. 2, a group of scientists in the Netherlands showed for the first time that it can have health benefits in obese humans. Eleven obese but healthy men had taken a relatively low dose of the compound daily for a month, [...]

Honey may reduce inflammation in cancer patients

Source: www.onlinenews.com.pk Author: staff A special type of indigenous honey available in New Zealand has special anti-infection properties that may help reduce inflammation in cancer patients, say scientists. Manuka honey's healing powers have been known for centuries. It has been used as a medicine since the ancient Egyptians, who regarded it as a cure all. The Christie Hospital in Didsbury, Manchester, have been using special honey-coated dressings at the Manchester Royal Infirmary since May, reported the online edition of BBC News. "Manuka honey has special anti-inflammatory and anti-infection properties and is believed to reduce the likelihood of infection," said Nick Slevin, a specialist at the hospital. The hospital is buying Manuka honey, produced by bees that mainly feed on the Manuka bush from New Zealand, in bulk. The doctors at the hospital now plan to use it on mouth and throat cancer patients. According to doctors, 60 patients at the hospital are taking part in a study to see if the honey can prevent infections that may be resistant to antibiotics.
