Review Case Reports
Immunoglobulin G4-related disease with Marked Eosinophilia: A Case Report and Literature Review.
We encountered a 78-year-old Japanese man with IgG4-related sialoadenitis complicated with marked eosinophilia. We diagnosed him with IgG4-RD (related disease) with a submandibular gland tumor, serum IgG4 elevation, IgG4-positive plasma cell infiltration, and storiform fibrosis. During follow-up after total incision of the submandibular gland, the peripheral eosinophil count was markedly elevated to 29,480/μL. ⋯ The patient exhibited a prompt response to corticosteroid therapy. His peripheral blood eosinophil count was the highest ever reported among similar cases. We also review previous cases of IgG4-RD with severe eosinophilia.

We herein report a case of hepatitis-associated aplastic anemia (HAAA) that occurred after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. In this patient, progressive pancytopenia observed two months after acute hepatitis following the second dose of the SARS-CoV-2 vaccine indicated the development of HAAA. ⋯ SARS-CoV-2 vaccination in children has only started relatively recently, so the range of side effects in children has not yet been thoroughly described. Therefore, we need to strengthen surveillance for symptoms of children who are vaccinated.

Case Reports
Mandibular Nodule Caused by Mycobacterium marinum with False Positive Interferon-γ Release Assay. A Case Report.
Mycobacterium marinum is a ubiquitous organism inhabiting both fresh and salt water. It can cause human diseases such as skin and soft tissue infection. ⋯ Here, we present a case of submandibular nodule caused by M. marinum with positive T-SPOT®. TB test, which was likely to be false positive.

Objective Interstitial lung disease (ILD) is the most critical manifestation in patients with rheumatoid arthritis (RA). In some cases, ILD may appear before the RA onset. Some patients with an initial diagnosis of idiopathic interstitial pneumonia (IIPs) develop RA; however, few studies have reported on its features, and the details remain unknown. ⋯ Pathological findings showed plasma cell infiltration, bronchus-associated lymphoid tissue (BALT), and bronchiolitis in the lobules. Cellular and destructive bronchiolitis was noticeable in many patients with ILD preceding RA and contributed to the destruction and dilation of the bronchiole. Conclusion In ILD patients with IIP, radiological and pathological findings with increased attenuation around the cysts, prominent inflammatory cell infiltration (especially in plasma cells), an increase in the BALT number, and cellular and destructive bronchiolitis might serve as helpful RA development indicators.

Observational Study
Antimicrobials in the Hospital are Unevenly Discontinued on Weekdays.
Objective Amid the global spread of antimicrobial resistance, antimicrobial stewardship should be further promoted in the clinical setting. Our previous study suggested an intra-week disproportion of discontinuation of broad-spectrum antibiotics. We therefore explored the generalization of this prescription trend by investigating the use of all intravenous antibiotics. ⋯ Similarly, antimicrobials were unevenly discontinued on the day after holidays compared to other days (p<0.001), with an approximately 2-fold difference. The use of antimicrobials in the hospital was thus unequally terminated on weekdays. Conclusion To further promote antimicrobial stewardship, clinicians should be aware of the influence of behavioral, environmental, and social factors on antimicrobial prescription, which is seemingly beyond medical indications.
