A research team from Germany analyzed the pathogenetic role and potential clinical usefulness of the epidermal growth factor receptor (EGFR) and the human epidermal growth factor receptor 2 (HER2) in patients with advanced biliary tract cancer (BTC). They found that routine testing and therapeutic targeting of HER2 does not seem to be useful in patients with BTC, while targeting EGFR may be promising. http://www.physorg.com/news174916004.html Medicine & Health Fri, 16 Oct 2009 18:50:01 EST news174916004 Acute hepatocellular injury is a commonly encountered phenomenon in patients with cholelithiasis and concomitant common bile duct (CBD) stones. However, in clinical practice, it seemed to occur also in cholelithiasis patients without evidence of CBD stones. Its incidence and final outcome necessitated clarification. http://www.physorg.com/news170423663.html Medicine & Health Tue, 25 Aug 2009 15:00:01 EST news170423663 Primary sclerosing cholangitis (PSC) is an idiopathic chronic cholestatic inflammatory liver disease characterized by diffuse fibrosing inflammation of intra- and/or extrahepatic bile ducts, resulting in bile duct obliteration, biliary cirrhosis, and eventually hepatic failure. One of the most common symptoms at the time of presentation of PSC is mild to severe abdominal pain localized in the right upper quadrant. However, the mechanisms responsible for the abdominal pain in PSC are not fully understood. http://www.physorg.com/news169120394.html Medicine & Health Mon, 10 Aug 2009 10:53:42 EST news169120394 Based on serum bank material, BA profiling was applied in IBD patients and healthy controls which showed that most but not all BA species were decreased to a different extent in CD and UC. BA decreases were highly pronounced in CD patients with surgical interventions in the gut. http://www.physorg.com/news166970717.html Medicine & Health Thu, 16 Jul 2009 17:50:01 EST news166970717 Overall prognosis for gallbladder cancer appears to be improving, although many patients still have incurable disease and poor survival rates, according to a report in the May issue of Archives of Surgery. http://www.physorg.com/news161882928.html Medicine & Health Mon, 18 May 2009 16:29:11 EST news161882928 Obesity and gallstones often go hand in hand. But not in mice developed at Washington University School of Medicine in St. Louis. Even when these mice eat high-fat diets, they don't get fat, but they do develop gallstones. Researchers say the findings offer clues about genetic factors related to gallstones, and they believe better understanding of those factors may one day allow physicians to monitor people at risk and even, perhaps, to intervene before gallstones become a serious problem. http://www.physorg.com/news160910670.html Medicine & Health Thu, 07 May 2009 10:25:00 EST news160910670 Physicians at Northwestern Memorial Hospital successfully removed a patient's gallbladder through the vagina, making them the first in the Midwest and the third in the country to perform the innovative procedure. The technique, known as NOTES -natural orifice translumenal endoscopic surgery -is gaining in popularity and has been characterized by many in the medical profession as laying the groundwork for truly "incisionless" surgery. http://www.physorg.com/news154786732.html Medicine & Health Wed, 25 Feb 2009 12:19:32 EST news154786732 In April of last year, surgeons at NewYork-Presbyterian Hospital/Columbia University Medical Center made headlines by removing a women's gallbladder through her uterus using a flexible endoscope, aided by several external incisions for added visibility. Now, they have performed the same procedure without a single external incision in what surgeons report may be the first surgery of its kind in the United States. http://www.physorg.com/news136466103.html Medicine & Health Mon, 28 Jul 2008 12:15:03 EST news136466103
