Objective To investigate current situation of disaster medicine courses among medical schools in China and perception of disaster management among medical students.Methods The survey was conducted among medical students from 14 medical schools in China.A questionnaire which included self-evaluation of ability to practice disaster management, status of disaster medicine courses and self-interest in learning disaster management was used.Results The survey showed that only a few of medical schools offered disaster medicine courses and the quality of current courses was not satisfying.Medical students were generally lack of systematic perception of disaster management, but they were interested in studying related knowledge.Conclusions It is necessary to design disaster medicine courses of high quality and promote them among medical schools in China.It can not only meet the requirements of medical students, but also effectively improve the response capacity of medical students and doctors when facing catastrophes.

OBJECTIVE: To analyze the clinical characteristics, prognosis and parallel clinical course of ovarian cancer (OC) and dermatomyositis (DM). METHODS: The medical records of 23 consecutive patients who were diagnosed with OC and DM and were treated at Peking Union Medical College Hospital (PUMCH) between 2002 and 2017 were reviewed. Propensity score matching method was used to match control group (OC patients without DM) at a ratio of 1:5. The correlation between OC and DM was measured using the Pearson correlation scatter plot and Pearson's r. Kaplan-Meier survival analysis and Cox proportional hazard regression analysis were performed to evaluate the prognostic factors. RESULTS: After matching, 23 patients who have the concurrence of OC and DM (DM group) and 115 patients diagnosed with OC alone (No DM group) were included. The 5-year overall survival rates (71.6% vs. 51.8%, p=0.020) and 5-year progression-free survival (30.5% vs. 0%, p=0.018) were poorer in DM group. Correlation between serum cancer antigen 125 (CA 125) and creatine kinase (CK) level was observed in 12 patients. The time between OC and DM diagnosis is significant through univariable analysis (p=0.021) but not in multivariable analysis in patients who have the concurrence of OC and DM. CONCLUSION: The concurrence of OC and DM as a paraneoplastic syndrome is rare and has a poor prognosis. The risk for patients diagnosed with DM is highest within 3 years before or after OC diagnosis. A correlation and a parallel clinical course exist between these 2 diseases.
