background gastrointestinal stromal tumors (gist) are the most common mesenchymal tumors of the gastrointestinal (gi) tract. they are usually c-kit positive and seen slightly more common in men. these tumors are seen in the gi tract from the esophagus to the anus with occasional invasion or metastasis. method in this retrospective study, we evaluated the prevalence of c-kit positive stromal tum...

there is documented evidence that infection in laboratory animals can often influence the outcome of experiments. all infections, apparent or inapparent, are likely to increase biological variability. as a research project concerning the diversity and distribution of parasites of rabbit and guinea pig in a conventional laboratory animal house, about 87 rabbits (from 700 ) and 105 guinea pigs (f...

vancomycin-resistant enterococci (vre) are becoming a major concern in medical practice. their increased prevalence and their ability to transfer vancomycin resistance to other bacteria have made them a subject of close scrutiny and intense investigation. colonization is usually acquired by susceptible hosts in an environment with a high rate of patient colonization with vre. the aim of this st...

although gastrointestinal involvement by metastatic malignant melanoma is common but primary gastrointestinal (gi) melanoma has been reported in rare cases. in this study we report two cases of primary gastrointestinal malignant melanoma that one of them is a known case of neurofibromatosis type 1(nf1). both cases showed no evidence of any lesions in skin and eye. malignant melanoma of gi tract...

the gastrointestinal tract is the most frequently involved extranodal location for malt* lymphomas, but malt lymphomas of the large intestine are rarely observed. a treatment for colorectal malt lymphoma has not yet been established. in colonic malt lymphomas, the literature suggests that surgical resection of localized lesion may be the best choice. in the present case, combination of multi-ag...

background: endoscopy of the upper gastrointestinal tract is the most accurate method for the diagnosis of most disease conditions associated with dyspepsia. however, endoscopy involves some discomfort, significant social inconvenience, and cost. attempts to identify those patients most likely to benefit from endoscopy have met with variable success. to evaluate endoscopic findings of the upper...
