Weight-loss surgery can cut cancer risk

Successful bariatric surgery allows morbidly obese patients to lose up to 70 percent of their excess weight and to maintain weight loss. The latest study by Dr. Nicolas Christou of the McGill University Health Centre (MUHC) and McGill University shows that this surgery also decreases the risk of developing cancer by up to 80 percent. Dr. Christou presented his preliminary results yesterday at the 25th Annual Meeting of the American Society for Metabolic and Bariatric Surgery........

Magnet-controlled camera in the body

Images from inside the body? It can be done with tiny cameras which the patient has to swallow. In the past there was no way of controlling the device as it passed through the body. Now it can be steered and stopped where desired, and even deliver images of the esophagus. Images of the inside of the intestine can be obtained even today: The patient swallows a camera that is no larger than a candy. It makes its way through the intestine and transmits images of the intestinal villi to an external receiver which the patient carries on a belt. This device stores the data so that the doctor can later analyze them and identify any hemorrhages or cysts. However, the camera is not very suitable for examinations of the esophagus and the stomach. The reason is that camera only takes about three or four seconds to make its way through the esophagus - producing two to four images per second - and once it reaches the stomach, its roughly five-gram weight causes it to drop very quickly to the lower wall of the stomach. In other words, it is too fast to deliver usable images. For examinations of the esophagus and the stomach, therefore, patients still have to swallow a rather thick endoscope........

Flat carbonated drinks not an effective alternative

Flat carbonated drinks should not be used as an alternative for oral rehydration solution to prevent dehydration in children with acute vomiting and diarrhoea, as per advice reported in the recent issue of Archives of Disease in Childhood. Oral rehydration solution is a liquid containing the ideal balance of salts and sugars for avoiding dehydration in people with gastroenteritis who are losing fluids, salts and sugars through diarrhoea and vomiting........

Steps leading to celiac disease

Researchers who last year identified a new genetic risk factor for coeliac disease, have, following continued research, discovered an additional seven gene regions implicated in causing the condition. The team, lead by David van Heel, Professor of Gastrointestinal Genetics at Barts and The London School of Medicine and Dentistry, have further demonstrated that of the nine coeliac gene regions now know, four of these are also predisposing factors for type 1 diabetes. Their research sheds light not only on the nature of coeliac disease, but on the common origins of both diseases. It is published online today (2 March 2008) in Nature Genetics........

Optimal care for inflammatory bowel disease

Inflammatory bowel disease (IBD) is a chronic recurrent gastrointestinal disease. The disease has a relatively higher morbidity in young adults, in whom growth, education, employment and wellbeing all are adversely influenced. Many guidelines for management of inflammatory bowel disease are available for bringing evidence-based medicine into full play to improve IBD patient care. What about the actual quality of care for patients with IBD in China?.......

Exercise to avoid gallstones!

A new University of Illinois study shows that exercise-trained mice get far fewer gallstones than sedentary mice and identifies potential mechanisms to explain why this occurs. The study, recently reported in the Journal of Applied Physiology, can be viewed online at: http://jap.physiology.org/cgi/reprint/01292.2007v1........

Camera in a pill

What if swallowing a pill with a camera could detect the earliest signs of cancer? The tiny camera is designed to take high-quality, color pictures in confined spaces. Such a device could find warning signs of esophageal cancer, the fastest growing cancer in the United States. A fundamentally new design has created a smaller endoscope that is more comfortable for the patient and cheaper to use than current technology. Its first use on a human, scanning for early signs of esophageal cancer, will be reported in an upcoming issue of IEEE Transactions on Biomedical Engineering........

How To Overcome Colonoscopy Fears?

Patients who have had a colonoscopy can play a life-saving role by encouraging other patients to follow through with their own colorectal cancer screenings, as per new research from the University of Pennsylvania School of Medicine. These peer coaches can provide important information to combat myths and fears that serve as barriers to colonoscopy issues patients say their doctors often fail to address. In a randomized trial, clinicians in the Division of General Internal Medicine studied patients who were at increased risk of missing their scheduled colon study appointment. They observed that those who received telephone mentoring from a trained peer coach were two times more likely to keep their first colonoscopy appointment than those who received an educational brochure about the procedure in the mail or received no peer or literature support........

Acid Reflux and Survival

Gastroesophageal reflux disease (GERD), often known as acid reflux, is a common problem that has been linked to cancers, asthma, recurrent aspiration and pulmonary fibrosis. A new study published in The American Journal of Gastroenterology examines whether GERD sufferers may have shorter lifespans than those without the disease........

bacteria in cows milk may cause Crohn's disease

Crohn's is a condition that affects one in 800 people in the UK and causes chronic intestinal inflammation, leading to pain, bleeding and diarrhoea. The team observed that a bacterium called Mycobacterium paratuberculosis releases a molecule that prevents a type of white blood cell from killing E.coli bacteria found in the body. E.coli is known to be present within Crohn's disease tissue in increased numbers........

Age, burden, divorce and heavy tea consumption

Gastroesophageal reflux disease (GERD) is a common disorder with a high incidence rate in adults of 10 - 38%. The diagnosis and therapy of GERD are therefore important because the disease, in addition to the highly disturbing typical symptoms, has a series of known consequences. The presence of GERD may affect patients' quality of life, decrease functional activity, and increase the risk of esophageal carcinoma........

New therapeutic targets in the treatment of ulcerative colitis

Social, environmental and dietary changes are linked to the changes of disease spectrum in a country. Ulcerative colitis has become a usually seen disease in China, probably due to extensive consumption of Western foods in recent years. Unfortunately, the etiology and pathogenesis of ulcerative colitis have not been clarified yet. Therefore, no effective etiological therapy is available at present. But a recent study published in issue 44 of the World Journal of Gastroenterology may offer new insight into this difficult-to-treat disease........

MRI predicts liver fibrosis, study says

Moderate to severe chronic liver disease can be predicted with the use of diffusion-weighted MRI (DWI), as per a recent study conducted by scientists at New York University Medical Center in New York, NY. Due to the increased occurence rate of chronic hepatitis in the United States, especially hepatitis C, there is a strong need for non-invasive methods to replace or supplement liver biopsy, which is relatively invasive and limited by interobserver variability and sampling error, said Bachir Taouli, MD, lead author of the study. DWI appears promising in that purpose, eventhough it needs validation in larger series, he said........

Night-time acid reflux can impact sleep

As per results of a survey presented at the 72nd Annual Scientific Meeting of the American College of Gastroenterology, nighttime acid reflux, along with some of the less typical manifestations or symptoms of gastroesophageal reflux disease (GERD), is linked to significant sleep impairment. In a recent national survey, scientists assessed the prevalence of sleep impairment among people with GERD and people without GERD based on response to an Internet survey of a general population of U.S. adults. Using a validated GERD screening tool, 701 respondents were identified with GERD and the remaining were controls. Bonnie Dean, MPH, PhD, of Cerner LifeSciences, Ronnie Fass, MD of the University of Arizona and their research team observed that sleep impairment was more common among people with GERD (41.9 percent) than those without GERD (19.4 percent). Scientists observed that 49.5 percent of respondents with nighttime GERD reported sleeping poorly often or most of the time, in comparison to 36.7 percent of people with daytime GERD........
