Case Reports
Symptomatic epiphrenic diverticulum in an older patient successfully treated nonsurgically.
Epiphrenic diverticulum is a rare condition commonly diagnosed in middle-aged adults. Symptoms include dysphagia and regurgitation, which are associated with underlying esophageal motility disorders. ⋯ The patient was successfully treated non-surgically without any complications. This case demonstrates that conservative treatment is an option for older high-risk patients.

The Epstein-Barr virus (EBV) is associated with many malignancies and autoimmune diseases, including multiple sclerosis. In addition, EBV rarely but occasionally causes central nervous system (CNS) complications. ⋯ Notably, intravenous rituximab ameliorated EBV reactivation and TM. Since the CNS infiltration rate of intravenous rituximab is markedly low, the clinical efficacy of rituximab against TM suggests that EBV reactivation may cause TM via immune-mediated mechanisms.

Case Reports
Successful Treatment of Malignant Lymphoma Following Transcatheter Aortic Valve Replacement: A Case Report.
A 67-year-old woman with severe aortic stenosis (AS) was transferred to our hospital for large B-cell lymphoma treatment. Because of her high risk of anthracycline-induced cardiotoxicity due to severe AS and low performance status, the patient was initially treated with doxorubicin-free chemotherapy. ⋯ Nine days after TAVR, the patient received the first cycle of anthracycline-containing chemotherapy (R-CHOP). Currently, 12 months after completing 4 cycles of R-CHOP, the patient remains in complete remission without having developed cardiotoxicity.

High-altitude pulmonary edema (HAPE) is a life-threatening, noncardiogenic pulmonary edema that occurs in unacclimatized individuals rapidly ascending to high altitudes above 2,500 m above sea level. Until the entity of HAPE was first identified in a case report published in Japan in 1966, the symptoms of severe dyspnea or coma occurring in climbers of the Japan Alps were incorrectly attributed to pneumonia or congestive heart failure. ⋯ Over the past 50 years, a series of studies have been conducted at Shinshu University to gain a better understanding of the characteristics of HAPE. This review summarizes the major achievements of these studies, including their clinical features, management, and pathogenesis of HAPE, particularly in the Japanese population.

The misdiagnosis of intestinal tuberculosis (ITB), such as Crohn's disease (CD), and subsequent treatment with immunosuppressive therapies can lead to severe outcomes. However, the differential diagnosis between these two conditions can be challenging. ⋯ In the international medical community, we encounter patients from countries, such as Myanmar, where tuberculosis is endemic. Therefore, it is necessary to understand the epidemiological background of each country to accurately distinguish between CD and ITB.
