Immune checkpoint inhibitors can affect any organ, including the salivary glands. A case of Sjögren's syndrome (SjS) induced by nivolumab for the treatment of gastric cancer is herein presented. Nivolumab treatment caused marked tumor shrinkage, but xerostomia developed after two cycles. ⋯ Prednisolone and pilocarpine hydrochloride did not relieve the symptoms. SjS is a relatively rare immune-related adverse event that might sometimes be overlooked. Since SjS can severely impair a patient's quality of life, oncologists should not miss any signs of salivary gland hypofunction and cooperate with specialists for SjS.

Three Cases of Ampullary Neuroendocrine Tumor Treated by Endoscopic Papillectomy: A Case Report and Literature Review.
We herein report three cases of patients with an ampullary neuroendocrine tumor (NET), who underwent endoscopic papillectomy (EP). No tumor recurrence or metastasis was detected in the patients for more than two years after EP. ⋯ However, as EP is less invasive than surgical resection, there are some reports of low-grade small ampullary NETs curatively treated by EP with long-term follow-up. We consider that EP may be a curative treatment for small and low-grade ampullary NETs without regional or distant metastasis.

Objective Brain parenchymal involvement in Behçet's disease (BD) (neuro-Behçet's disease, NB) can be classified into acute type (ANB) and chronic progressive type (CPNB) based on differences in the clinical course and responses to corticosteroid treatment. The present study developed evidence-based recommendations for the management of NB. Methods The task force of the research subcommittee consisted of seven board-certified rheumatologists (one was also a board-certified neurologist) and three board-certified neurologists. ⋯ The strength of each recommendation was established based on the evidence level as well as the rate of agreement. Conclusion The recommendations generated in this study are based on the results of uncontrolled evidence from open trials, retrospective cohort studies and expert opinions, due to the lack of randomized clinical trials. Nevertheless, these recommendations can be used for international studies, although verification by further properly designed controlled clinical trials is required.

An 83-year-old man was hospitalized for coronavirus disease 2019 (COVID-19) after a 10-day history of a persistent fever. Chest computed tomography showed extensive non-segmental ground glass opacity. ⋯ Two days of polymyxin B-immobilized fiber column-direct hemoperfusion (PMX-DHP) with adjunctive corticosteroid prevented his respiratory condition from worsening. For rapidly progressive COVID-19 cases, the early use of PMX-DHP may avoid the need for mechanical ventilation by suppressing local inflammation of the lung.
