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.

Review Case Reports
Pancreatic Neuroendocrine Neoplasm Concomitant with Branch-duct Intraductal Papillary Mucinous Neoplasm: A Case Report and Literature Review.
Reports of pancreatic neuroendocrine neoplasm (P-NEN) concomitant with intraductal papillary mucinous neoplasm (IPMN) are gradually increasing. However, many of these cases were diagnosed in the resected specimen incidentally. ⋯ These findings suggest that P-NEN as well as pancreatic ductal adenocarcinoma should be considered as concurrent tumors developing in patients with IPMNs. EUS is an essential modality when evaluating IPMN for detecting small lesions concomitant with IPMN.
