Tuberculosis is a common etiology of granulomatous interstitial nephritis (GIN). However, the absence of evidence of lung involvement and lack of mycobacterial isolation in cultures make the etiological diagnosis and treatment decision challenging. ⋯ Despite no evidence of tuberculosis except for a positive interferon-gamma release assay (IGRA), the patient was successfully treated with anti-tuberculosis drugs. Our case suggests that anti-tuberculosis therapy should be considered for patients with IGRA-positive GIN after excluding other etiologies.

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.

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.

A 19-year-old man with pectus excavatum developed symptomatic persistent atrial fibrillation (AF). He had no remarkable medical history or comorbidities and had not exercised intensely during childhood. Electrical cardioversion and pre-treatment with amiodarone for two months failed to maintain sinus rhythm. ⋯ Voltage mapping revealed that the right and left atrial voltages were preserved within the normal limit. However, radiofrequency catheter ablation successfully eliminated recurrent persistent AF. No recurrence was observed during eight months of follow-up.

Case Reports
Reversible Brain Atrophy in Cryptogenic New-onset Refractory Status Epilepticus: A Case Report.
Cryptogenic new-onset refractory status epilepticus (C-NORSE) is a neurologic emergency condition characterized by refractory status epilepticus (RSE) of unknown cause. Brain atrophy in a setting of C-NORSE is usually irreversible. ⋯ Her cognitive function also gradually improved, with a reduction in seizure frequency. Early initiation of intensive immunotherapy with anti-seizure medications may have minimized irreversible brain damage associated with RSE, resulting in a relatively good outcome.
