The histopathological findings of immune checkpoint inhibitor (ICI)-induced pancreatitis have rarely been reported. A 56-year-old man with squamous cell carcinoma of the lung with bone metastasis was being treated with pembrolizumab, an anti-programmed cell death protein-1 antibody. After 13 doses, he was referred to our department due to pancreatitis. ⋯ However, a histological examination showed neutrophil-based inflammatory cell infiltration and acinar-ductal metaplasia. Immunostaining showed CD8-positive T lymphocyte infiltration. This case revealed the characteristic histopathology of pembrolizumab-induced pancreatitis, which was previously poorly understood.

Objective In patients with coronavirus disease 2019 (COVID-19), understanding the timeline of oxygen demand and severe respiratory failure, such as intensive care unit (ICU) admission, may clarify the therapeutic window when home-care treatment is possible and help determine the timing of treatment in hospitalized patients to improve the respiratory status. We examined the timeline of respiratory status in hospitalized patients with moderate-to-severe COVID-19 in terms of oxygen demand and ICU admission. Methods We retrospectively assessed all patients with COVID-19 who were admitted to our hospital between February 2020 and February 2021 and required supplemental oxygen. ⋯ Only 2 of 66 patients (3.0%) were admitted to the ICU six days or later after the initiation of supplemental oxygen. Conclusion Physicians should carefully monitor each patient's condition after eight days from symptom onset. New therapies and their early administration are needed to reduce the frequency of respiratory failure in COVID-19 patients.

Objective The coronavirus disease (COVID-19) pandemic has altered the delivery of medical care. The present study evaluated the impact of COVID-19 on the outcomes of unresectable pancreatic cancer (PC) patients who received end-of-life care. Methods We retrospectively compared the management of PC patients during the COVID-19 pandemic (from April 2020 to March 2021) to the preceding year, which was unaffected by the pandemic (from April 2019 to March 2020), based on a prospectively maintained institutional database. ⋯ A multivariate analysis revealed that death during the COVID-19 exposed period was independently associated with home death (odds ratio: 4.536, 95% confidence interval: 2.527-8.140, p<0.001). Conclusions While the COVID-19 pandemic did not seem to influence chemotherapeutic treatment for PC patients at our institution, it had a large impact on end-of-life care. These findings may promote discussion about end-of-life care in Japan.

Ebstein's anomaly is an uncommon congenital disorder affecting the tricuspid valve. We herein report a 38-year-old woman who experienced consciousness and sensory disturbance during treatment for heart failure caused by Ebstein's anomaly. ⋯ Ebstein's anomaly concomitant with moyamoya disease is extremely rare. However, we should consider the possibility of this rare but important concurrence when treating patients with heart failure due to Ebstein's anomaly to avoid excessive diuresis and vasodilation and irreversible brain injury.

We encountered a case of refractory adult-onset Still's disease (AOSD) with two relapses. Prednisolone and methotrexate were begun as induction therapy, resulting in the patient's first relapse during tapering of prednisolone. ⋯ While lactate dehydrogenase (LDH) levels and white blood cell (WBC) counts increased in both relapses, interleukin-6 (IL-6) suppression resulted in stable C-reactive protein and ferritin levels in the second relapse. A comparison of the two relapses indicated that increases in both WBC counts and LDH levels can aid in the diagnosis of AOSD relapse.
