ABSTRACT
Although the COVID-19 pandemic affects the emergency medical service (EMS) system, little is known about the impact of the COVID-19 pandemic on the prognosis of emergency patients. This study aimed to reveal the impact of the COVID-19 pandemic on the EMS system and patient outcomes. We included patients transported by ambulance who were registered in a population-based registry of patients transported by ambulance. The endpoints of this study were the incident number of patients transported by ambulance each month and the number of deaths among these patients admitted to hospital each month. The incidence rate ratio (IRR) and 95% confidence interval (CI) using a Poisson regression model with the year 2019 as the reference were calculated. A total of 500,194 patients were transported in 2019, whereas 443,321 patients were transported in 2020, indicating a significant decrease in the number of emergency patients transported by ambulance (IRR: 0.89, 95% CI: 0.88-0.89). The number of deaths of emergency patients admitted to hospital was 11,931 in 2019 and remained unchanged at 11,963 in 2020 (IRR: 1.00, 95% CI: 0.98-1.03). The incidence of emergency patients transported by ambulance decreased during the COVID-19 pandemic in 2020, but the mortality of emergency patients admitted to hospital did not change in this study.
ABSTRACT
We experienced a case of inflammatory carcinoma, which has been well controlled by chemotherapy, especially, vinorelbine, S-1 and trastuzumab. A 54-year-old woman was diagnosed as inflammatory carcinoma with T4d, N3c, M0 in Stage III c. The lesion was diagnosed as invasive ductal carcinoma, scirrhous, ER(-), PgR(-), HER2(3+) by core needle biopsy, The skin lesion was diagnosed as dermal lymphatic carcinomatosis by skin biopsy. The following chemotherapy was performed: FEC(5-FU 500 mg/m2, epirubicin 70 mg/m2, cyclophosphamide 500 mg/m2) followed by docetaxel(DOC 70 mg/m/2), every 3 weeks, each 6 times; after that, sequentially, vinorelbine (25 mg/m2)+trastuzumab (2 mg/kg every week), UFT(300 mg, daily)+cyclophosphamide (100 mg 2 weeks on, 1 week off)+trastuzumab (continued) and S-1 (120 mg/body 4 weeks on, 2 weeks off)+trastuzumab (continued). The patient has been well controlled by the chemotherapy with good QOL. Especially vinorelbine, S-1, and trastuzumab contributed to the disappearance of skin lesion.
