Review Case Reports
Metachronous Esophageal Ulcers after Immune-mediated Colitis Due to Immune Checkpoint Inhibitor Therapy: A Case Report and Literature Review.
Although cases of gastrointestinal toxicity of pembrolizumab have been reported, cases of acute immune-mediated colitis accompanied with metachronous esophageal disorders (esophagitis and ulcer) are rare. We herein report a case of acute colitis and metachronous esophageal ulcers due to an immune-related adverse event following concomitant pembrolizumab chemotherapy for lung adenocarcinoma. To our knowledge, there have so far been no reports of cases in which both acute immune-mediated colitis and metachronous esophageal ulcers developed. We therefore report the details of this case along with a review of the pertinent literature.

Objective The present study analyzed the psychological status of healthcare workers in Japan and the influencing factors during the 2019 coronavirus disease pandemic. Methods An online survey was conducted from July 22 to August 21, 2020. A total of 328 of the 1,029 medical staff members in our university hospital participated in the study. ⋯ The multivariate regression analysis showed that four factors were extracted as independent 12-item General Health Questionnaire-related factors: the lack of a sense of mission as a medical professional, the burden of the change in the quality of work, the lack of understanding about virus infectivity, and a strong sense of duty. Conclusion In summary, we found a high prevalence of psychological distress among healthcare workers during the 2019 coronavirus disease outbreak in Japan. Independent risk factors for psychological distress were the burden of the change in the quality of work, the lack of understanding about virus infectivity, a sense of responsibility, and the lack of a strong motivation and drive to help.

Multicenter Study
Immediate or Interval Endoscopic Papillary Large-balloon Dilation after Limited Endoscopic Sphincterotomy for Bile Duct Stone Removal.
Objective Endoscopic papillary large-balloon dilation (EPLBD) with limited endoscopic sphincterotomy (EST) is widely used for removing multiple large common bile duct (CBD) stones. However, the safety and effectiveness of immediate EPLBD after limited EST and EPLBD at an interval after limited EST is unclear. Thus, this multicenter retrospective study was conducted to examine this matter. ⋯ The immediate EPLBD group had significantly fewer mean ERCP sessions for complete stone removal and a significantly lower rate of endoscopic mechanical lithotripsy (EML) usage than the interval EPLBD group [1.6 vs. 2.4 sessions, p<0.001; and 4/33 (12.1%) vs. 12/33 (36.4%), p=0.042, respectively]. Conclusion The incidence of post-ERCP complications in the immediate EPLBD group was not significantly different from that in the interval EPLBD group. Compared with interval EPLBD, immediate EPLBD may result in a reduced number of ERCP sessions for complete stone clearance and reduce the rate of EML usage.

Multicenter Study Observational Study
Gender Differences in the Circadian and Seasonal Variations in Patients with Takotsubo Syndrome: A Multicenter Registry at Eight University Hospitals in East Japan.
Objective The aim of this study was to clarify the circadian and seasonal variations in addition to identify sex-based differences in Japanese patients with Takotsubo syndrome (TTS). Methods The authors conducted a retrospective observational study to analyse the differences between the groups based on sex. Patients The patients were registered out of each institute registry of the acute coronary syndrome (ACS) which contains a total of 10,622 cases in eight academic hospitals in east Japan. ⋯ Conclusion In a multicenter study in Japan, seasonal variation was observed in the female group but not in the male group. Circadian variation was observed in both groups. These results suggested that the pathogenesis and clinical features of TTS might therefore differ according to sex.

We herein report two cases of thrombotic thrombocytopenic purpura (TTP) complicated by other autoimmune disorders, autoimmune hepatitis and immune thrombocytopenia, respectively. In both cases, corticosteroids were continuously administered for the treatment of preceding autoimmune disorders. ⋯ Both patients achieved a sufficient response, and have never had any recurrence as of the last follow-up dates. The early introduction of rituximab could be an effective treatment option in TTP patients complicated with other autoimmune disorders.
