American College of Gastroenterology, Oct. 28-Nov. 1, 2011Last Updated: November 07, 2011.
The annual meeting of the American College of Gastroenterology was held from Oct. 28 to Nov. 1 in Washington, D.C., and attracted more than 4,500 participants from around the world, including gastroenterology and digestive specialists and other health care professionals. The conference featured presentations focusing on clinical updates in gastroenterology and hepatology as well as the latest advances in digestive health and gastrointestinal disorders.
In an effort to understand smoking's impact on colorectal cancer, Carolyn Anderson, M.D., of Dartmouth Medical School in Hanover, N.H., and colleagues sought to assess the risk of colorectal cancer in those who had quit smoking, especially women. The investigators evaluated gender differences in colorectal cancer risk associated with smoking among 2,428 male and female individuals, above 45 years of age, who had quit smoking.
"It is known that men and women have different rates of advanced colorectal neoplasia. These data show that there are also gender differences with regard to smoking exposure and rate of neoplasia," Anderson said.
Among both men and women, the investigators found that the risk of colorectal cancer was significantly elevated for those who were current smokers or previous smokers who quit five years prior to screening colonoscopy. The risk of colorectal cancer was still elevated for women who had quit smoking six to 10 years prior to screening colonoscopy; however, this elevated risk did not apply to men.
"Men and women with colon cancers have different outcomes. The question is: why? Undoubtedly, understanding the mechanisms for these differences may help understand the smoking-related carcinogenesis and perhaps prevent cancer," Anderson added.
In another study, Pia Prakash, M.D., of the George Washington University Hospital in Washington, D.C., and colleagues found that it may be difficult to determine whether commonly used cosmetic products contain gluten.
"Our research showed that, of the top 10 selling cosmetic companies, none offers information about gluten contained in their cosmetics on their official Web sites. Furthermore, very few offer a list of ingredients for individual cosmetic products. Even when a list of ingredients is available, it is difficult to determine whether ingredients contain gluten or not, making cosmetic products a potential hazard for celiac patients," Prakash said. "Health care providers and clinicians need to be aware that many products, including cosmetics and body products, contain gluten. Celiac patients should not only be educated on the importance of following a gluten-free diet, but also on the potential harm of gluten-containing products such as lipsticks, foundations/face powders, and lotions."
Scott Gabbard, M.D., of the Dartmouth-Hitchcock Medical Center in Lebanon, N.H., and colleagues evaluated risk factors for small intestinal bacterial growth (SIBO), including the impact of lifestyle factors such as alcohol consumption and tobacco use, as well as the use of proton pump inhibitors (PPIs) and H2 receptor antagonists (H2RAs). The investigators evaluated the charts of 198 patients who underwent lactulose hydrogen breath testing (LHBT) between 2008 and 2010.
"We found that alcohol consumption was [a] strong predictor of positive LHBT and SIBO. Those who consumed any amount of alcohol had a significantly higher rate of a positive LHBT when compared to those who did not drink: 59.8 versus 39.6 percent," Gabbard said. "Of the 198 patients in the study, 92 drank some amount of alcohol. Interestingly, only four of the 92 patients drank more than the U.S. Department of Agriculture recommendation of a moderate amount of alcohol -- up to one drink per day for women and up to two drinks per day for men. All levels of consumption had higher rates of a positive LHBT compared to those who abstained."
The investigators did not find any association between smoking, PPI use, or H2RA use and SIBO.
"This study adds to the growing data that lifestyle factors such as diet and alcohol consumption play a very important role in patients with functional bowel disorders," Gabbard concluded.
