ABSTRACT
Although gastric cancer patients have a high incidence and risk of colorectal cancer, evidence is lacking regarding whether early gastric neoplasms (EGNs), such as gastric adenomas and early gastric cancer, are risk factors for colorectal adenoma. This study aimed to investigate the incidence of colorectal adenomas in patients with EGN. This prospective study was conducted between January 2015 and December 2016. Of the 307 patients who underwent gastric endoscopic submucosal dissection for EGN, 110 patients were enrolled in the EGN group, and 110 age- and sex-matched healthy persons from the screening population were included in the control group in a 1:1 ratio. Demographic factors and results of colonoscopy, including quality assessment, were collected, and analyzed. No significant differences in the quality of colonoscopy, including bowel preparation, cecal intubation rate, and withdrawal time between the 2 groups, were observed. The incidence of colorectal adenoma was significantly higher in the EGN group than in the control group (55.5% vs 26.4%, P = .001). Multivariate analysis confirmed that old age (odds ratio: 1.04, 95% confidence interval: 1.01-1.08, P = .005) and a history of EGN (odds ratio: 4.99, 95% confidence interval: 2.60-9.57, P = .001) were independent risk factors for colorectal adenoma. This is the first prospective study to reflect the quality indicator of colonoscopy and confirmed that old age and a history of EGN are significant risk factors for colorectal adenomas. Therefore, more stringent colonoscopy surveillance should be considered in elderly patients with EGN.

Non-Hodgkin's lymphoma of B-cell type is the second most common neoplasm after Kaposi's sarcoma among patients with human immunodeficiency virus infection. Most non-Hodgkin's lymphoma cases that are associated with acquired immunodeficiency syndrome (AIDS) involve extranodal sites, especially the digestive tract and the central nervous system. We report a case of multiple jejunal intussusception caused by Burkitt lymphoma in a 42-year-old AIDS patient. Upper gastrointestinal endoscopy and surgical biopsy were performed and a complete diagnostic study including histological and immunohistochemical analyses showed Burkitt lymphoma.
ABSTRACT
The purpose of this study was to report a case of a previously healthy 20-year-old woman diagnosed with splenic infarction following infectious mononucleosis (IM) by Epstein-Barr virus (EBV) infection and to perform the first systematic review of the clinical characteristics of splenic infarction associated with IM. A systematic review was conducted using English, French, and Japanese literatures of splenic infarction associated with IM due to EBV infection published between 1961 and 2015 in PubMed Medline. A total of 19 cases were extracted from the collected articles. Left upper quadrant (LUQ) pain was observed in 15 (79%) patients. Splenectomy was performed in five (26%) cases, among which four patients presented with stable vital signs. Splenic rupture was accompanied in two (10%) patients. The median time from the onset of IM symptoms to the diagnosis of splenic infarction was 5 days (range, 1-25 days). Fourteen (74%) of 19 patients experienced improvement through medical treatment, and there were no deaths. Splenic infarction associated with IM due to EBV infection can show a favorable clinical outcome after medical treatment. Clinicians should consider the possibility of splenic infarction when patients with IM experience LUQ pain. J. Med. Virol. 89:332-336, 2017. © 2016 Wiley Periodicals, Inc.
