Objective Screening and surveillance methodologies for Lynch syndrome (LS) in Japan. This study assessed the changes in LS knowledge and practice trends. Methods In 2020 and 2022, 2 questionnaire surveys were administered to 3574 councilors of the Japanese Society of Gastroenterology to assess changes in LS-related knowledge and practices. ⋯ However, the rise in UTS suggests a potential bias from doctors with heightened interest in LS, which may have influenced the findings. Conclusion The number of newly diagnosed and currently monitored patients with LS in Japan has been increasing, likely due to expanded screening practices. However, the potential bias introduced by the increased adoption of UTS should be considered when interpreting these results.

Objective Dysphagia is a common and disabling symptom in patients with myasthenia gravis (MG). Moreover, it is caused by muscle weakness or fatigability in the pharynx, swallowing, and respiration discoordination. The current study aimed to establish a novel method for evaluating swallowing difficulty in patients with MG. ⋯ Results Patients with MG who presented with dysphagia had abnormal excessive expiratory flows, clusters of excessive expiratory flows, high inspiratory flows, and prolonged EMG patterns compared to healthy controls (all p <0.05). Among these parameters, the incidence of an excessive expiratory flow, cluster of excessive expiratory flows, and prolonged EMG pattern significantly improved after treatment (p <0.05). Conclusion Based on this study, the respiratory patterns and submental sEMG are likely to reflect the severity of pharyngeal muscle weakness/fatigability and thus can be used as a quantitative parameter for dysphagia in patients with MG.

A 75-year-old man diagnosed with esophageal cancer and lung metastasis received a combination of fluorouracil, cisplatin, and pembrolizumab. During pembrolizumab maintenance therapy, lymphoproliferative lesions at the lips and mouth and multiple lymph node swellings appeared. ⋯ Rituximab was administered, resulting in the improvement of the OIIA-LPD. The emergence of an OIIA-LPD merits close attention in patients receiving immune checkpoint inhibitors.
