Kaposi sarcoma usually manifests as skin or mucosal lesions; involvement in visceral organs such as the gastrointestinal tract is rare. Kaposi sarcoma can occur in immunocompromised patients receiving immunosuppressive therapy, in which case it is known as iatrogenic Kaposi sarcoma or drug-induced Kaposi sarcoma. Intestinal Kaposi sarcoma in patients with inflammatory bowel disease is extremely rare. Case presentation A 46-year-old East Asian male with recently diagnosed Crohn's disease was administered azathioprine and prednisolone; however, the patient complained of persistent abdominal pain and diarrhea following treatment. Endoscopy revealed small bowel Kaposi sarcoma. The patient was treated with systemic chemotherapy successfully without relapse. Conclusions This is the fifth case of Kaposi sarcoma developed over the small intestine in a patient with Crohn's disease following administration of immunomodulators. Additionally, this case indicated that even short-term immunomodulator use can induce Kaposi sarcoma in patients with inflammatory bowel disease. Thus, in patients with inflammatory bowel disease, if symptoms are aggravated or do not abate after immunomodulators prescription, and before intending to upgrade immunomodulators, endoscopy should be considered. Finally, chemotherapy can also be considered if both medication withdrawal and surgical intervention are not feasible. <br> Mon, 11 Dec 2023 06:01:27 GMT https://ir.cnu.edu.tw/handle/310902800/34053 title: A Digital Evaluation Approach for Nodule Size Analysis of Pearlite Mixture Phase Structure in Steel abstract: This study employed a digital evaluation approach for determining the nodule size of a no heat-treatment pearlite structure, as well as the grain size of the ferrite phase via an image morphology process methodology. The grain size of steel has great influence on the mechanical properties of manufactured materials, making it a necessary metallographic inspection item for materials. The properties affected by grain size include hardness, failure life, ultimate stress, electric characteristics, and heat expansion rate. In general, grain size inspection has two approaches: manual comparison and digital computation. In manual comparison, the comparison of standard graphics or the observation of an eyepiece inserted on a microscope can be progressed. For digital computation, planimetric and intercept procedures are applied according to international standards. This study thus applied an image processing algorithm to identify the observed image after undergoing seven times of erosion and dilation operations. <br> Fri, 18 Nov 2022 03:21:52 GMT https://ir.cnu.edu.tw/handle/310902800/27145 title: 電子書學習情境與雲端協同服務於技職教育課程之運用─總計劃 Wed, 26 Feb 2014 03:44:23 GMT https://ir.cnu.edu.tw/handle/310902800/26226 title: 老年人跌倒動作模擬系統之建立與應用評估 Tue, 05 Mar 2013 06:08:30 GMT
