Infective endocarditis (IE) may be acquired in the community as community-acquired (CA) IE or in the healthcare setting. In Japan, cases of CA-methicillin-resistant Staphylococcus aureus (MRSA) infection as skin infection have been increasing. ⋯ However, only a few IE cases induced by USA300 have been reported. We herein report a 64-year-old man who developed CA-IE from a furuncle caused by USA300 MRSA producing PVL and ACME, which resulted in complications of meningitis.

Objective Strict follow-up is recommended for branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs) to avoid missing the development of high-risk stigmata (HRS) at a premalignant stage. This study explored the risk factors associated with the development of HRS during follow-up. Methods We performed a retrospective analysis of 283 patients with BD-IPMN, treated at Okayama University Hospital in Japan between January 2009 and December 2016. ⋯ The rate of HRS development was significantly higher in cases with multiple WFs than in the other cases (p<0.0001). Conclusion MPD dilation, rapid cyst growth, and multiple WFs were significant risk factors for the development of HRS. In the presence of such features, it is necessary to closely follow the development of HRS and avoid missing the best opportunity to perform surgical intervention.

Case Reports
Neuromyelitis Optica Complicated by Ornithine Transcarbamylase Deficiency Treated Safely with Pulse Steroid Therapy.
Steroid administration to patients with urea cycle disorders can cause hyperammonemia. We encountered a 36-year-old woman with neuromyelitis optica (NMO) complicated by ornithine transcarbamylase (OTC) deficiency. By reducing the doses of steroids and adequate infusion management, we were able to administer pulse steroid therapy without any severe complications. This case indicates the safety of steroid treatment in patients with urea cycle disorders.

Case Reports
A Case of Gastric Cancer with Multiple Lymph Node Enlargement at the Time of the Sarcoidosis Diagnosis.
An 80-year-old woman was found to have a 40-mm depressed-type gastric cancer. Computed tomography showed multiple lymph node enlargement, including paraaortic lymph nodes. The extent of lymph node enlargement was significant compared with the depth of the primary lesion. ⋯ In the dissected lymph nodes, noncaseating granuloma was found without metastasis of adenocarcinoma. Immunohistochemical staining using Propionibacterium acnes-specific antibodies showed a large number of P. acnes-positive cells in the granulomas. Finally, the tumor was diagnosed as early-stage gastric cancer and sarcoidosis.

Background Homeless persons are those who carry out their activities of daily living in city parks and other facilities. Little is known about homeless patients with lung cancer in Japan. Therefore, we characterized the clinical features and outcomes of homeless people in metropolitan Tokyo. ⋯ During the study, nine patients died in the hospital, and four were lost to follow up. Conclusion It is difficult for homeless patients to continue chemotherapy, and they often quit therapy willfully. Therefore, it is necessary to develop an education and health insurance support system to ensure treatment continuity in a good social environment.
