Objective Seasonal influenza affects healthcare demand. However, the efficacy of anti-influenza drugs, particularly among young patients at a low risk of complications, has rarely been evaluated. Therefore, we evaluated the efficacy of anti-influenza drugs against seasonal influenza in healthy young and middle-aged adults. ⋯ Oseltamivir (300 mg/day for 5 days) showed the largest reduction in time to fever alleviation by -19.1 [95% confidence interval (CI): -29.4, -10.7] h compared with a placebo. Baloxavir marboxil (40 mg/day) reduced the time to symptom alleviation by -28.2 (95% CI: -42.7, -13.7) h, and peramivir (300 mg/day) administered by intravenous infusion for 1 day reduced the time to resumption of usual activities by -43.5 (95% CI: -72.8, -14.2) h. Conclusion Several pharmaceutical treatments were able to reduce the recovery time for fever and symptom alleviation and resumption of usual activities in young and middle-aged adults with seasonal influenza without increasing the risk of complications.

Review Case Reports
Kluyvera georgiana Bacteremia Due to Acute Cholangitis: A Report of the First Known Case and a Literature Review.
We herein present the first known case of bacteremia caused by Kluyvera georgiana in a 67-year-old female undergoing chemotherapy for recurrent pancreatic cancer. The patient underwent choledochojejunotomy and thereafter developed ascending cholangitis. ⋯ Although Kluyvera spp. infections are typically sensitive to antibiotics, multidrug resistance is possible. This case highlights the importance of the early diagnosis and treatment of K. georgiana and its associated risk factors.

Review Case Reports
An Extremely Delayed Onset of Frey Syndrome: A Case Report and Literature Review.
We report the case of an 80-year-old man with Frey syndrome that developed 30 years postoperatively, which is an exceptionally long period before its occurrence. Sweating and flushing occurred on only the side of his face where the surgery was performed, and he had no other causative abnormalities. ⋯ Various surgical methods to prevent this syndrome have been explored, but complete prevention has not yet been achieved. These findings suggest that the underlying pathophysiology of Frey syndrome may be more complex than previously recognized.

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.
