Review Case Reports
Atezolizumab-induced Encephalitis in a Patient with Hepatocellular Carcinoma: A Case Report and Literature Review.
We herein report a case of encephalitis in a 42-year-old woman with hepatocellular carcinoma following atezolizumab plus bevacizumab therapy. After two weeks of treatment, she was admitted for a high fever, impaired consciousness, and convulsive seizure refractory to diazepam. Magnetic resonance imaging revealed a hyperintense splenial lesion. ⋯ Steroid pulse therapy improved the fever and seizure. However, her incomplete right-sided paralysis and aphasia persisted. This is the first case report of encephalitis caused by atezolizumab plus bevacizumab therapy for hepatocellular carcinoma.

Eosinophilic cholangiopathy (EC) presents with thickening and stenosis of the bile duct wall that is histologically characterized by eosinophil infiltration. The diagnosis is often difficult. We herein report a patient who had been followed up with a diagnosis of primary sclerosing cholangitis but had a final diagnosis of EC based on eosinophilia, histological findings of bile duct and liver biopsy specimens, and a review of a previous surgical specimen of the gallbladder. Antigen tests, isolation from her house, and accidental re-exposure to the antigen revealed that the causative antigen was the mite Dermatophagoides pteronyssinus.

Review Case Reports
Severe Gastrointestinal Disorder due to Capecitabine Associated with Dihydropyrimidine Dehydrogenase Deficiency: A Case Report and Literature Review.
Dihydropyrimidine dehydrogenase (DPD) deficiency induces severe adverse events in patients receiving fluoropyrimidines. We encountered a 64-year-old DPD-deficient man with a severe capecitabine-related gastrointestinal disorder. He received capecitabine-containing chemotherapy after rectal cancer resection. ⋯ Endoscopy revealed mucosal shedding with bleeding throughout the gastrointestinal tract. DPD deficiency was suspected because he developed many severe adverse events of capecitabine early and was finally confirmed based on the finding of a low DPD activity level in peripheral blood mononuclear cells. After one month of intensive care, hemostasis and mucosal healing were noted, although his gastrointestinal function did not improve, and he had persistent nutritional management issues.

Meta Analysis
Seizure Control in Patients with Epilepsy During the COVID-19 Pandemic: A Systematic Review and Meta-analysis.
Objective To investigate seizure control in patients with epilepsy during the coronavirus disease 2019 (COVID-19) pandemic. Method A systematic review and meta-analysis was conducted, and the MEDLINE, EMBASE, CENTRAL, and ClinicalTrials.gov databases were comprehensively searched for relevant studies. Studies that reported seizure control in patients with epilepsy during the COVID-19 pandemic were included. ⋯ The pooled proportion of seizure worsening in the subgroup analysis was 18.9% (95% CI: 13.5-25.0; I2=96%; p<0.01). Conclusion Although the heterogeneity was high, our results showed a relatively high incidence of seizure worsening during the COVID-19 pandemic. During the COVID-19 pandemic, physicians should be aware of the likelihood of worsening seizures in patients with epilepsy.

Review Case Reports
Adult T Cell Leukemia/Lymphoma Becoming Apparent During Treatment of Pulmonary Abscess and Empyema Caused by Nocardia asiatica: A Case Report and Review of the Literature.
Nocardia is a Gram-positive bacterium that causes opportunistic infections. Nocardia asiatica was newly isolated in 2004, and there have been no case reports describing the empyema caused by N. asiatica. ⋯ We herein report a case in which immunosuppression attributable to ATL may have led to pulmonary abscess and empyema caused by N. asiatica. Our case demonstrates the need to investigate causes of immunosuppression, including ATL, in patients showing nocardiosis.
