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.

A 71-year-old woman with recurring stage IV hepatocellular carcinoma (HCC) was admitted to our hospital while being treated with atezolizumab and bevacizumab and complained of fatigue, vomiting, and appetite loss. The following were noted on admission: serum glucose level, 633 mg/dL; metabolic acidemia (HCO3- of 19.5 mmol/L); remarkably low serum and urinary C-peptide levels (0.16 ng/mL and ≤1.5 μg/day, respectively); and urinary ketone body level, 4,197 μmol/L. She was diagnosed with atezolizumab-induced fulminant type 1 diabetes mellitus (T1DM), and insulin therapy improved the symptoms. To our knowledge, this a novel report of atezolizumab-induced fulminant T1DM in an HCC patient.

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.

Case Reports
Lung Adenocarcinoma with Chronic Lymphocytic Leukemia Mimicking Bone Metastasis: A Case Report.
A 77-year-old man was referred to our hospital for abnormal thoracic radiographs. Computed tomography (CT) revealed a 20-mm subpleural ground-glass opacity in the right S6 area. ⋯ A right lower lung lobectomy was performed for the lung adenocarcinoma (cT1bN0M0, stage IA2). An aggressive biopsy of the bone lesion confirmed a rare case of double primary malignancies, which determined the patient's treatment and outcomes.

A 38-year-old man was taken to hospital with generalized clonic seizure. Brain magnetic resonance imaging (MRI) showed multiple ring-enhancing lesions centered in the left frontoparietal lobe. ⋯ The lesions worsened after anti-tuberculosis drugs were administered, which we considered to be a paradoxical response and continued treatment. A genetic diagnosis of M. tuberculosis using FFPE specimens is useful for diagnosing tuberculoma.
