Drug Shows Promise As New Treatment For Gut Tumor

A drug that is already an approved therapy for some cancers also might be an effective secondary treatment for a rare tumor of the gastrointestinal tract, according to a team led by researchers from the University of Pittsburgh Cancer Institute (UPCI). The findings, based on experiments using cell cultures, were published in the Jan. 1 issue of Cancer Research. Bortezomib, or Velcade, is used to treat multiple myeloma and certain lymphomas, said Anette Duensing, M.D., assistant professor of pathology, University of Pittsburgh School of Medicine, an investigator in the Cancer Virology Program, UPCI, and senior author of the study. It works in part by preventing the degradation of certain proteins, which when elevated, induce apoptosis, or programmed cell death, in the cancerous cells.

Incidental Findings At MRI-Enterography

MRI is increasingly used in the assessment of small bowel CD. Unlike conventional radiology, MRI enables visualization of disease extension beyond the intestinal wall, i.e., abscesses and fistulas. However, some extra-intestinal findings are unexpected and without relation to CD. The ability to detect incidental findings presents a clinical dilemma. On one hand, modern imaging techniques may detect early extra-intestinal malignant disease or disease requiring clinical intervention, thereby reducing morbidity and mortality. On the other hand, incidental findings may lead to further diagnostic work-up or surgery of benign lesions causing increased morbidity.

An Etiological Role For H. Pylori In Autoimmune Gastritis

Experimental animal studies have shown that H. pylori shares several antigenic regions in common with acid secreting cells in gastric mucosa. Antibodies triggered by H. pylori destroy acid secreting cells due this antigenic mimicry. H. pylori infection is very common in humans, and about half of the infected patients develop atrophic changes over the years. In end stage severe atrophy, H. pylori disappears and signs of a previous infection are difficult to detect. This research, lead by Dr. L Veijola and her colleagues in the University of Helsinki, Finland, has recently been published on January 7, 2010 in World Journal of Gastroenterology.

Physician First In Virginia To Deliver New Cancer Fighting Technique

The world's smallest flexible microscope is diagnosing some big diseases and allowing physicians to treat patients on the spot. Dr. Michel Kahaleh, associate professor of medicine in the Division of Gastroenterology and Hepatology at the University of Virginia Health System, is the only physician in Virginia currently using probe-based confocal laser endomicroscopy (pCLE). pCLE is a technique that lets him view live tissue in real time at the cellular level. This allows the identification of cancer with pinpoint precision and permits precise removal of the diseased tissue. "Until now, if we found suspicious tissue during one of these diagnostic procedures, we often had to randomly sample it and send it to the laboratory for analysis, which can take up to a week, " says Kahaleh.

Oral Sodium Phosphate Laxative Inducing Hyperphosphatemia Relates With Weight

Colon cleansing is used widely for colonoscopic exploration and colonic and gynecological surgery. Oral sodium phosphate (OSP) solution is the osmotic laxative most commonly used for this purpose. It is known that OSP can induce severe hyperphosphatemia and hypocalcemia due to excessive absorption of phosphates, and there have been reports of deaths and irreversible dialysis-requiring renal insufficiency. However, no prospective studies have investigated the prevalence of hyperphosphatemia in low-risk patients. A research article published on December 21, 2009 in the World Journal of Gastroenterology addresses this problem. A research team from Argentina recruited one hundred consecutive ASA .

Research Reveals Pycnogenol Is Effective In Reducing Severe Symptoms Of Hemorrhoids, Including Bleeding

According to the National Digestive Diseases Information Clearinghouse, about half of the U.S. population will have hemorrhoids by the age of 50. While the most common prescription to treat hemorrhoids is over-the-counter remedies, most patients do not report symptoms of acute hemorrhoidal attacks to their doctor until they are in severe distress, including bleeding. A study published in a recent issue of Phytotherapy Research reveals Pycnogenol® (pic-noj-en-all), an antioxidant plant extract from the bark of the French maritime pine tree, has important anti-inflammatory and anti-thrombotic properties that may be beneficial in patients with hemorrhoids, both for acute and chronic treatment, and in preventing new attacks.
