Steroids decrease the intestinal wall edema and thus the symptoms improve or disappear. The role of gastric acid inhibition in HSP patients remain

unknown but we opted to continue this while he is maintained on oral steroids. Upon follow-up, the previously noted purpuric rashes resolved, however, there was the appearance of new purpuric RGFP966 in vitro rashes on the lower extremities with occasional vague hypogastric pain but there was no recurrence of the bloody stools. The plan is to continue patient on oral prednisone and continue to monitor response. Key Word(s): 1. Henoch Schoenlein; 2. HSP; 3. GI bleed; 4.

University Northern Yokohama Hospital Objective: Magnifying selleck inhibitor chromoendoscopy (MC) is a Japanese standard diagnostic method for endoscopically predicting a massively invasive submucosal colorectal cancer (SMm) which has the possibility of metastasis Recently developed ultra-magnifying (450-fold) endoscopy “endocytoscopy (EC)” was also reported to be useful for predicting SMm. The aim was to assess the additional value of EC to MC for diagnosing colorectal lesions. Methods: Consecutive lesions which were resected after colonoscopical examination with use of EC were enrolled in this retrospective

study between May 2005 and Febulary 2013 in Showa University Northern Yokohama Hospital. At colonoscopy, the on-site endoscopists diagnosed each lesion on the basis of MC+EC findings after assessing it on the basis of MC findings alone. The 4��8C diagnostic abilities of MC+EC were compared to those of MC alone with reference to the histopathology of the resected specimens. As main outcome measure, the diagnostic abilities of predicting both neoplastic change and SMm were evaluated according to Kudo’s pit pattern classification and the EC classification. In addition, inter- and intraobserver agreement for both MC and EC diagnoses were evaluated by using fifty randomly selected images among six endoscopists at intervals of one month. Results: Overall, 357 patients with 391 specimens were available for analysis. Of them, there were 41 non-neoplastic lesions, 272 dysplasias, 12 slightly invasive submucosal cancers, and 74 SMms. The main results were shown in the table.
