[Clinical features and high resolution CT imaging evolution of coronavirus disease 2019].

Objective: To investigate the clinical manifestations of the clinical characteristics of 141 patients with coronavirus disease 2019 (COVID-19) and the imaging evolution characteristics of High Resolution CT (HRCT) in the chest. Methods: From January 20, 2020 to February 8, 141 COVID-19 patients in Renmin Hospital of Wuhan University, 77 males and 64 females, with a median age of 49 (9,87) , were retrospectively analyzed. The clinical features, laboratory examination indexes and HRCT evolution findings of 141 COVID-19 patients were analyzed. Results: Laboratory examinations of 141 COVID-19 patients showed a decrease in white blood cell count and lymphocyte ratio. Among the 141 patients with COVID-19, fever (>37.5 â„ƒ) was the most common clinical manifestation in 139 cases (98.58%) , and occasionally non-respiratory symptoms such as diarrhea in 4 cases (2.84%) . 141 patients with COVID-19 had abnormal HRCT. 52 (36.88%) chest HRCT images showed ground-glass opacity (GGO) , mainly under pleural; 23 (16.31%) GGO with focal consolidation; 27 (19.15%) small flaky shadows; 20 cases (14.18%) large flaky consolidation shadows; 48 cases (34.04%) bronchovascular bundle thickening and vascular penetrating signs; 5 cases (3.55%) had air bronchial signs; 7 cases (4.96%) of small nodule shadows; 5 cases (3.55%) of fibrosis, grid shadows or strand shadows.135 cases (95.74%) were positive for the first time nucleic acid test, 6 cases (4.26%) were negative, and 71 cases (50.35%) of common type, 47 cases (33.33%) of severe type and 23 cases (16.31%) of critical type were found during the same period. The average time from onset of each type to the first CT examination was: (2.51±1.32) , (5.02±2.01) , and (5.91±1.76) days; 19 (19/47, 40.43%) of which were severe for the first time CT classification worsened at the second examination and lessened at the third examination. 141 cases (100%) were positive for the second nucleic acid test, and the HRCT results for the same period were 44 cases (31.21%) of common type, 53 cases (37.59%) of severe type, and 44 cases (31.21%) of critical type; the average interval time was (3.32±1.61) , (3.93±1.84) , (4.15±1.57) days;the third nucleic acid test were positive among 113 cases and 28 cases were negative, HRCT results of the same period were 79 cases (56.03%) of common type, 46 cases (32.62%) of severe type, and 16 cases (11.35%) of critical type;the average interval from the first CT examination were: (5.59±1.83) , (7.32±1.37) , (7.55±1.78) days. The differences in CT typing at different time were statistically significant (P<0.05) . Conclusion: The clinical features of COVID-19 and HRCT images are diverse, extensive GGO and infiltrates in both lungs are typical. Viral nucleic acid tests usually occur earlier or at the same time as the CT examination positive, and there are false negatives in nucleic acid tests. In some epidemiological backgrounds, CT imaging manifestations and evolutionary characteristics are of great significance for early warning of lung injury, assessment of disease severity, and assistance in clinical typing and post-treatment follow-up.

[Management strategies for three patients with gynecological malignancies during the outbreak of COVID-19].

Objective: To explore the management strategies for patients with gynecological malignant tumors during the outbreak and transmission of COVID-19. Methods: We retrospectively analyzed the clinical characteristics, treatment, and disease outcomes of three patients with gynecological malignancies associated with COVID-19 in Renmin Hospital of Wuhan University, and proposed management strategies for patients with gynecological tumors underriskof COVID-19. Results: Based on the national diagnosis and treatment protocol as well as research progress for COVID-19, three patients with COVID-19 were treated. Meanwhile, they were also appropriately adjusted the treatment plan in accordance with the clinical guidelines for gynecological tumors. Pneumonia was cured in 2 patients, and one patient died of COVID-19. Conclusions: Patients with gynecological malignant tumors are high-risk groups prone to COVID-19, and gynecological oncologists need to carry out education, prevention, control and treatment according to specific conditions. While, actively preventing and controlling COVID-19, the diagnosis and treatment of gynecological malignant tumors should be carried out in an orderly and safe manner.
