Drink warm water to ease effects of colon probes?

Drink warm water to ease effects of colon probes?

Drinking warm water seems to relax the bowel and improve the comfort of colonoscopy, as well as the “completeness” of the procedure, hint findings of a study from Korea.

Colonoscopy involves inserting a thin, flexible scope into the colon to look for cancer or polyps, which are growths that can become cancerous. With colonoscopy, the entire length of the colon can be inspected. It is considered the most sensitive way to screen for colon cancer.

However, “incomplete” colonoscopy examinations — when the full length of the colon can not be examined, for whatever reason — do occur and may lead to some small growths in the colon being missed, Dr. Jae J. Kim, at Sungkyunkwan University School of Medicine in Seoul noted in an email to Reuters Health.

In their study, Kim’s team found that they were able to completely examine more of the large intestine surface (98.4 percent on average) of patients who drank 2 liters (approximately 2 quarts) of warm water just prior to undergoing colonoscopy.

By contrast, colonoscopy reached lesser surface amounts (90.6 and 92.2 percent, respectively) in patients who drank 2 liters of cold water or no water, the researchers report in the American Journal of Gastroenterology.

Nose treatment cuts hospital-acquired infections

Nose treatment cuts hospital-acquired infections

If you’re checking into the hospital for surgery, doctors may soon be swabbing your nose in an effort to prevent an infection from appearing after your operation.

Researchers in the Netherlands said on Wednesday they were able to cut the risk of a common bacterium by nearly 60 percent by first looking for signs of it in the nose and then treating it with an antibiotic nasal gel and full body wash.

The treatment combination also shaved two days off a typical 14-day stay in the hospital.

Hospital-acquired infections are a major problem in medicine, so doctors are always looking for the best way to reduce the risk.

About 27 million surgeries are done just in the United States each year, and in as many as half a million cases, infections occur at the site of surgery.

Up to 30 percent of those infections are caused by strains of the bacterium Staphylococcus aureus, which otherwise benignly resides in the nose and on the skin.

The new study, published in the New England Journal of Medicine, used a rapid test to identify which patients, most of whom were scheduled to undergo surgery, had the bacteria in at least one nostril.

The 504 patients treated with the antibiotic nose gel mupirocin, also known as Bactroban, and washed with chlorhexidine, a common ingredient in mouthwash, developed an S. aureus infection 3.4 percent of the time. The rate for 413 volunteers given placebo treatment was 7.7 percent.

Bowel disease drugs increase cancer risk: study

Bowel disease drugs increase cancer risk: study

Some treatments for inflammatory bowel disease increase the risk of infection-related cancers, French scientists said on Monday, but the benefits of the drugs still outweigh the risks.

Thiopurine drugs — immunosuppressive medicines that inhibit the body’s immune system — are regularly used to treat inflammatory bowel disease, the researchers said, but can increase the risk of cancers linked to viral infections.

Laurent Beaugerie and colleagues at the Saint-Antoine hospital in Paris looked at more than 19,000 patients with inflammatory bowel disease. Around 30 percent of the patients were taking thiopurines, 14 percent had stopped taking them and 56 percent had never taken them.

Following up after almost 3 years, the researchers found 23 new cases of cancers — one of Hodgkin’s lymphoma and 22 of non-Hodgkin lymphoma.

Statistical analysis showed that patients receiving thiopurines — like azathioprine produced by several generic drugmakers and by GlaxoSmithKline as Imuran — had a more than five-fold increased risk of lymphoma compared with those who had never received the drugs, the researchers said in a study published in The Lancet journal.

Older male patients with a longer history of inflammatory bowel disease also had increased lymphoma cancer risk.

“The absolute cumulative risk…in young patients receiving a 10-year course of thiopurines remains low — (less than 1 percent) — and does not undermine the positive risk-benefit ratio of these drugs,” the researchers wrote.

But for elderly patients and for unlimited treatment periods, more studies were needed to assess the risk, they said.

Commenting on the study, Geert D’Haens of the Imelda GI Clinical Research Center and Paul Rutgeerts University Hospital Gasthuisberg, both in Belgium, said doctors should be cautious in prescribing thiopurines for prolonged periods.
