Case Reports
Hilar Malignant Biliary Obstruction Treated with Four Metallic Stents Involving a New Slim Device.
Endoscopic hilar multiple stenting is challenging. A 68-year-old patient had self-expandable metallic stents (SEMSs) inserted for unresectable hilar malignant biliary obstruction. ⋯ After the placement of these four SEMSs, the liver abscess improved. The new SEMS was effective for hilar multiple biliary drainage.

A 59-year-old woman who had been diagnosed with cirrhotic primary biliary cholangitis (PBC) 5 years earlier was admitted for severe jaundice (total bilirubin: 30.1 mg/dL). We suspected that her cirrhotic PBC had deteriorated acutely for some reason. ⋯ Histopathological findings revealed cirrhosis and submassive loss and necrosis of hepatocytes. Clinicians should consider the possibility of acute HEV infection as a trigger for acute PBC exacerbation.

Case Reports
A Case of Diffuse Alveolar Hemorrhage Associated with Dilated Cardiomyopathy and Sleep Apnea Syndrome.
We herein report a case of diffuse alveolar hemorrhage (DAH) associated with dilated cardiomyopathy (DCM) and sleep apnea syndrome (SAS) in a 47-year-old man. The patient exhibited recurring dyspnea and bloody sputum. Chest radiography showed bilateral diffuse infiltrative opacities without pleural effusion. ⋯ Laboratory and pathological findings ruled out the possibility of collagen diseases and vasculitis. Overnight polysomnography revealed concomitant severe obstructive SAS. Treatment with continuous positive-pressure ventilation and pharmacological therapy for DCM prevented recurrence of DAH.

Case Reports
Severe Measles Encephalitis and Acute Disseminated Encephalomyelitis in an Immunocompetent Japanese Young Male.
Measles encephalitis rarely affects young adults and has no established treatment strategy. This brief report described the rare case of an immunocompetent 30-year-old man with severe measles pneumonia and encephalitis, following the autoimmune disease acute disseminated encephalomyelitis, during a large measles outbreak in 2018 in Japan. With multidisciplinary treatments, including corticosteroids, intravenous immunoglobulins, vitamin A, and therapeutic plasma exchange, the patient was successfully treated. This case provides a new strategy for treating measles encephalitis and its complications during measles outbreak.

We treated a 51-year-old Japanese man with chronic hepatitis B (viral load 7.6 LC/mL, genotype C). Hepatitis B virus DNA and HBe antigen were undetectable during the administration of the nucleic acid analogs (NUCs) lamivudine and adefovir, although the concentration of HBs antigen (HBsAg) was 851.2 IU/mL. ⋯ During this time, HBsAg reached undetectable concentrations, and HBs antibody was detected and continued to be detectable during the three-year follow-up. These unprecedented findings suggest that IFN may contribute to the seroclearance of HBsAg in patients treated with NUCs.
