Case Reports
A Case of Cytokine Release Syndrome Induced by Immune-checkpoint Inhibitor Therapy for Non-small-cell Lung Cancer.
Immune-related adverse events, including autoimmune toxicity, may develop as a consequence of immune-checkpoint inhibitor (ICI) cancer therapy. Cytokine release syndrome (CRS) is a severe and life-threatening cytokine-associated toxicity that can develop after adoptive T-cell therapy. ⋯ He recovered by steroid pulse therapy and tocilizumab. CRS is a rare but life-threatening adverse event of ICI therapy and therefore warrants awareness.

Objective Percutaneous patent foramen ovale (PFO) closure is a procedure widely used to prevent recurrence of cryptogenic stroke. Since December 2019, the Amplatzer PFO occluder device has been available in Japan through medical insurance. However, data on the clinical experience with this device are lacking, as it has been approved for use in only a limited number of institutions. ⋯ Almost all cases (92.9%) were performed with a 25-mm device and without significant complications within approximately 1 hour. Conclusion Percutaneous closure using Amplatzer PFO occluder is a safe procedure for Japanese patients. However, further investigations with a larger sample and longer follow-up are needed to confirm this result.

A 79-year-old man with underlying alcoholic liver cirrhosis presented with complaints of a fever, abdominal pain, and difficulty walking. A diagnostic work-up revealed liver atrophy and chylous ascites, and spontaneous bacterial peritonitis (SBP) was diagnosed based on the cell and neutrophil counts. ⋯ Bcc is often multidrug-resistant and difficult to treat. SBP caused by Bcc has been rarely reported and may have a serious course, thus necessitating caution.
