Virtual Colonoscopy on the Rise in Hospitals


Virtual colonoscopy -- a screening method for colorectal cancer that's a noninvasive alternative to the traditional colonoscopy -- is becoming more common in U.S. hospitals.

A virtual colonoscopy requires the same preparation to empty the bowels as a standard colonoscopy, but instead of inserting a viewing tube into the colon and rectum, a CT scan of the abdomen is done to obtain two- and three-dimensional images of the intestines. Because the test will cause only minor discomfort, sedation is not needed
.
In a recent study reported in the Journal of the American College of Radiology(Volume 8, page 169), researchers looked at American Hospital Association surveys from 2005 to 2008 that asked whether hospitals provided virtual colonoscopy, also called computed tomographic colonography, or CTC.

They found that between 2005 and 2008, the number of hospitals offering this approach rose from 13 to 17 percent. In 2008, most hospitals (69 percent) that offered CTC also offered traditional colonoscopy. Some hospital representatives said that they adopted the CTC approach to offer an alternative for frail older patients or to address long waiting times for colonoscopy.

Virtual colonoscopy does have drawbacks: Patients still have to clean out their colon before screening, which can be uncomfortable; patients are exposed to radiation during the procedure; and the provider can't use the approach to remove any growths. Also, in 2009, Medicare rules stated that the program wouldn't cover CTC for general screening, though it would be covered in specific situations.

Adopting a Vegetarian Diet

Adopting a vegetarian diet has become a popular choice for individuals looking to improve their health, particularly as heart disease and obesity rates continue to rise in many parts of the world. Vegetarians tend to have lower cholesterol levels and consume fewer trans fats than those who consume meat and dairy products. However, to maintain good health, vegetarians must ensure they obtain the right amount of nutrients from their vegan diets. By taking care to plan their diets carefully, vegetarians can enjoy a satisfying and tasty way of life. While there is no established vegan diet, it is widely agreed that with so many vegetarian diets to choose from, the choice is ultimately up to the individual.

THE TRUTH ABOUT MENOPAUSE, WEIGHT GAIN AND "THE POOCH"

By Colleen McCleery, MD, OB/GYN—Exuberan® by Virtua Menopause is a mixed bag of little surprises. While most women look forward to saying goodbye to tampons and pads, far fewer are excited to now experience hot flashes and night sweats. And it’s probably fair to say that weight gain is the least popular and often least expected “side effect” of this hormonal shift. Considering many women struggle with their weight on a good day, it’s not surprising that this is the number one complaint from patients who are going through this transition. The biology of menopause During the late 40s to mid-50s, a hormone called FSH (follicle-stimulating hormone) increases and no longer performs its job to regulate the ovaries. During this increase in FSH, other hormones like estrogen, progesterone and testosterone decrease. A decrease in testosterone can lead to weight gain and decreased energy. And, not surprisingly, estrogen loss has far-reaching effects beyond hot flashes. It contribut...
