Case Reports
A Case of Bile Duct Mixed Neuroendocrine-nonendocrine Neoplasm with a Complete Response to Chemoradiotherapy.
The incidence of neuroendocrine carcinomas arising from the bile duct is low, and that of mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) is even lower; therefore, there is no standard treatment for MiNENs. Choosing the appropriate treatment in clinical practice is difficult. We herein report a case of unresectable extrahepatic bile duct MiNEN in a 66-year-old man who received curative chemoradiotherapy and achieved a complete response, remaining recurrence-free for 2.5 years. We consider the findings of this case to be valuable in selecting a treatment strategy for unresectable bile duct MiNENs.

Objective Cataract and chronic kidney disease (CKD) occur with increasing frequency with age and share common risk factors including smoking, diabetes, and hypertension. We evaluated the risk of incident cataract surgery in patients with non-dialysis-dependent CKD and dialysis-dependent CKD compared to non-CKD patients, while taking into account the competing risk of death. Methods The participants included 1,839 patients from Sado General Hospital enrolled in the Project in Sado for Total Health (PROST) between June 2008 and December 2016 (54% men; mean age, 69 years). ⋯ After adjusting for potential confounding factors, the dialysis-dependent CKD group [hazard ratio (HR) 2.48; 95% CI 1.43-4.31], but not the non-dialysis-dependent CKD group (HR, 1.01; 95% CI 0.74-1.38), had a higher risk of cataract surgery than the non-CKD group. However, this association was no longer significant according to a competing risk analysis (sub-hazard ratio, 1.67; 95% CI 0.93-3.03). Conclusion Dialysis-dependent CKD patients were found to have an increased risk of cataract surgery; however, the association was attenuated and no longer significant when death was considered a competing risk.

Acute hemolytic transfusion reaction (AHTR) is a rare but life-threatening complication of transfusion. We herein report a case of anti-Jkb IgM-related AHTR. ⋯ We confirmed the presence of anti-Jkb IgM in the patient's serum by flow cytometry. This case demonstrates the potential utility of flow cytometry for IgM detection.

Objective This study examined the prevalence of migraine in nurses in Japan, which, to our knowledge, has not been documented in English. Methods From April to May 2021, we administered a questionnaire to 229 nurses working at Keio University Hospital to investigate the prevalence and characteristics of headache among nurses in Japan. Headaches were classified as migraine or tension-type headache (TTH) based on the International Classification of Headache Disorders 3rd edition (ICHD-3). ⋯ In many cases, headache-associated symptoms are more important than laterality or other characteristics for the diagnosis. Many nurses are treated for headaches without a correct diagnosis. Further education regarding primary headaches may be necessary for health practitioners as well as society.
