Gastric high-grade dysplasia is an important premalignant lesion in gastric epithelial cells and has a high possibility of transforming to adenocarcinoma. Therefore, biopsy-proven high-grade dysplasia should be treated with en bloc resection methods such as endoscopic mucosal resection or endoscopic submucosal dissection (ESD). We report the case of a 63-year-old male patient, diagnosed with ga...

BACKGROUND Acromioclavicular (AC) joint injuries, particularly sprains, are common in athletic populations and may result in significant time lost to injury. However, surprisingly, little is known of the epidemiology of this injury. PURPOSE To define the incidence of AC joint injuries and to determine the risk factors for injury. STUDY DESIGN Descriptive epidemiological study. METHODS A l...

It is presently not clear if ovarian carcinomas arise de novo or from benign precursors (cystadenomas) and if high-grade malignant tumors (carcinomas) develop from preexisting low-grade carcinomas. The presence of allelic losses on chromosome 11p15.5 distinguishes high-grade ovarian carcinomas from either low-grade carcinomas or cystadenomas. We therefore examined the distribution of such losse...

this prospective study, conducted in 8 cities of iran from 1999 to 2000. out of total 16,573 trauma patients, 106 (0.63%) included in this study had renal injury. this study aimed at investigation of incidence, etiology and management of renal trauma patients in iran. they were 87 (82.1%) male and 19 (17.9%) female patients. renal trauma mechanism was mainly blunt injury (93.4%). road traffic c...

i.p.s. hypergroups are canonical hypergroups such that$[forall(a,x),a+xni x]longrightarrow[a+x=x].$i.p.s. hypergroups were investigated in [1], [2], [3], [4] and it was proved thatif the order is less than 9, they are strongly canonical (see [13]). in this paperwe obtain the sequences of fuzzy sets and of join spaces determined (see [8])by all i.p.s. hypergroups of order seven. for the meaning ...
