Rituximab is an effective treatment for frequently relapsing/steroid-dependent nephrotic syndrome, but there is concern about infections caused by humoral immunodeficiency. We herein report a case of prolonged (>7 weeks) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. ⋯ Treatment with casirivimab and imdevimab (REGEN-COV) monoclonal antibodies in combination with remdesivir resulted in complete clearance of the infection. The REGEN-COV antibody cocktail may improve the outcome of SARS-CoV-2 infection in patients with humoral immunodeficiency.

Objective Quantification of patient encounters during internal medicine residency training is challenging. At present, there are no established strategies for evaluating the whole inpatient experience in Japan. We hypothesized that the Diagnosis Procedure Combination (DPC) database, which is widely used in Japan, might be a useful tool for such an evaluation. ⋯ There was a moderately positive correlation between the total patient-days and extra working hours in these residents, but no such correlation was noted in the rate of monthly patient encounters and extra working hours among residents as a whole. Conclusion The DPC-based quantification of patient encounters during residency training appears effective in evaluating the coverage of the current J-OSLER list. Owing to its wide availability and generalization, this matching method may be useful as a universal tool for assessing internal medicine programs.

Posterior reversible encephalopathy syndrome is an uncommon syndrome in exertional rhabdomyolysis. We herein report a case of rhabdomyolysis and acute kidney injury after intense exercise. ⋯ This case report describes an infrequent neurological complication of exertional rhabdomyolysis. Understanding the range of complications is critical for improving patient outcomes.

We herein report a 45-year-old-man with multiple foreign body granulomas in the lungs caused by polytetrafluoroethylene (PTFE). A mass in the right lower lobe of the lung and bilateral centrilobular lung nodules were found unexpectedly during the patient's visit to a hospital for a respiratory infection. ⋯ The presence of fluorine in the granulomatous lesions was confirmed using an electron probe microanalyzer with wavelength dispersive spectrometer. Fluorine is a component of PTFE and is not found in normal lung tissue.
