Multicenter Study Observational Study
Rabeprazole Coadministration Controls Ulcer Recurrence in Patients on Low-dose Aspirin Therapy: A Multicenter Prospective Study.
Objective To evaluate the efficacy and safety of rabeprazole coadministration with low-dose aspirin (LDA). Methods From 2015 to 2018, we conducted a large-scale, multicenter, prospective observational study to assess the safety and efficacy of treatment with rabeprazole (5 or 10 mg/day) in combination with LDA. Results The incidence of adverse reactions was 0.73% (11/1,513 patients), with no serious adverse reactions. ⋯ The cumulative recurrence rate of ulcers by Week 52 (Kaplan-Meier estimates) was 3.50% (range, 1.56-7.75%). No gastrointestinal bleeding was reported. Conclusion Rabeprazole in combination with LDA appears as safe and effective in real-world situations as in clinical trials.

A 79-year-old man was admitted with worsening cough, dyspnea, and increased ground-glass opacity on chest computed tomography (CT). He had been diagnosed with idiopathic pulmonary fibrosis given the absence of an identifiable cause of interstitial pneumonia, chest CT findings, and absence of lymphocytosis in bronchoalveolar lavage (BAL) fluid. ⋯ A re-evaluation with BAL showed lymphocytosis, and clinical improvement with antigen avoidance confirmed the diagnosis of fibrotic hypersensitivity pneumonitis (fHP). A re-evaluation with BAL at disease deterioration after possible exposure to inciting antigen can facilitate a correct fHP diagnosis.

Case Reports
A Tumefactive Fibroinflammatory Lesion of the Head and Neck Mimicking Immunoglobulin G4-related Disease.
A 67-year-old woman with a 5-year history of recurrent swollen eyelids and epistaxis, diagnosed as immunoglobulin G4-related diseases (IgG4-RD) based on hyper-IgG4-emia and IgG4-positive cell infiltration to the lesion, was referred to our department due to recurrent symptoms despite corticosteroid therapies. Computed tomography revealed an osteoclastic sinus mass with prominent neutrophil infiltration and necrosis that was incompatible with IgG4-RD histopathologically. Finally, she was diagnosed with a tumefactive fibroinflammatory lesion (TFIL) of the head and neck and treated with high-dose corticosteroids. Physicians should remember that TFIL can mimic IgG4-RD in the head and neck region with prominent neutrophil infiltration and necrosis.

We herein report two cases of thymic cancer with Lynch syndrome showing a high frequency of microsatellite instability and loss of mismatch repair protein expression without MLH1 promoter hyper-methylation. In Case 1, a 71-year-old man had a pathogenic germline variant in MLH1 and underwent tumor resection. ⋯ In Case 2, a 43-year-old man underwent genetic testing that also showed a pathogenic germline variant in MLH1. Since these two cases had MLH variants, we suspect a possible association between thymic cancer with Lynch syndrome and germline pathogenic variants in MLH1.

Fabry disease is an X-linked lysosomal storage disorder due to mutations in the alpha-galactosidase A gene, which leads to the accumulation of globotriaosylceramide in various organs. In Fabry disease with end-stage renal disease (ESRD), cerebrovascular events are lethal, even with enzyme replacement therapy (ERT). ⋯ We herein report a case of recurrent cerebrovascular complications under ERT in a Fabry disease patient, progressing to ESRD on peritoneal dialysis. Further studies are warranted, but Fabry disease patients with ESRD receiving ERT might need careful long-term follow-up in cases with cerebrovascular manifestations.
