Epstein-Barr virus (EBV) is the cause of infectious mononucleosis, which is characterized by fever, lymphadenopathy, and sore throat. On the other hand, gastrointestinal symptoms of EBV infection like dyspepsia, abdominal pain are non-specific and rarely encountered, which means it is difficult to diagnose gastric involvement of EBV infection without suspicion. The relation between gastric carcinoma and gastric lymphoma associated with EBV infection is well defined, but relations with other EBV-associated gastrointestinal diseases such as gastritis and peptic ulcer disease have rarely been reported. We report a case of benign gastric ulcer with EBV infection confirmed by endoscopic and histological findings.

Ischemic colitis is the consequence of a sudden reduction in colon blood supply, which in turn results in ischemic injury. The splenic flexure and rectosigmoid junction are the areas most often affected. Ischemic colitis occurs with greater frequency in the elderly and is caused by various medications and procedures. Pseudoephedrine acts as a vasoconstrictor directly affecting adrenal receptors of nasal mucous membrane. Pseudoephedrine occasionally causes vascular insufficiency due to intense vasoconstriction, even at standard doses. Ischemic colitis associated with pseudoephedrine has been reported in other countries,, but it has never been reported in Korea. In this paper, we describe 3 cases of ischemic colitis that occurred after taking pseudoephedrine for nasal congestion.
