Objectives. The objectives of this study were to identify the clinical features and chest computed tomography (CT) findings of coronavirus disease 2019 (COVID-19) patients and to compare the characteristics of patients diagnosed in Wuhan and in other areas of China by integrating the findings reported in previous studies.Methods. We conducted a proportion meta-analysis to integrate the results of previous studies identified in online databases, and subsequently compared the overlapping of 95% confidence intervals (CIs) between locations of diagnosis. The heterogeneity of the results of the included studies was also demonstrated.Results. Nine studies with level IV evidence were considered to be eligible for the meta-analysis, and a comparative analysis was only possible between patients diagnosed in Wuhan and outside of Wuhan in China. Fever (84.8%; 95% CI, 78.5% to 90.1%) was identified as the most common clinical manifestation in all COVID-19 patients, and signs of respiratory infection were also frequently present in these patients. When comparing the clinical features according to the location of diagnosis, fever and dyspnea were less frequent in patients diagnosed outside of Wuhan (fever: 78.1%; 95% CI, 73.2% to 82.7%; dyspnea: 3.80%; 95% CI, 0.13% to 12.22%) than in patients diagnosed in Wuhan (fever: 91.7%; 95% CI, 88.0% to 94.8%; dyspnea: 21.1%; 95% CI, 13.2% to 30.3%). The chest CT findings exhibited no significant differences between the groups.Conclusion. Fever was found to be the most common symptom in COVID-19, and respiratory infection signs were also commonly present. Fever and dyspnea were less frequently observed in the patients diagnosed outside of Wuhan, which should be considered in COVID-19 screening programs. These results may be attributable to the earlier diagnosis of the disease and the younger age of patients outside of Wuhan although further analysis is needed. The role of chest CT in COVID-19 diagnosis is inconclusive based on this study.

Background and ObjectivesThe aims of this study were to evaluate the relationship between tinnitus and the level of anxiety and depression experienced by subjective tinnitus patients, and to determine the effect of the level of anxiety and depression to the results of tinnitus treatment.Subjects and MethodsA total of 104 patients were included in this study. All the patients conducted Tinnitus Handicap Inventory (THI), Beck Depression Inventory (BDI), State Trait Anxiety Inventory 1, 2 (STAI 1, 2) to evaluate their psychometric properties. The subjective patterns of tinnitus before and after treatment were assessed through questionnaires.ResultsSignificant correlation between THI scores and BDI, STAI 1, 2 scores were observed in the moderate and severe tinnitus group. The patients were classified into two groups depending on their THI scores, and also classified into two groups according to BDI, STAI 1, 2 results. Analysis of differences after treatment indicated significantly improved VAS scores after treatment in all groups.ConclusionsThe subjective level of tinnitus is significantly related with depression and anxiety symptoms when inconvenience caused by tinnitus was moderate or over. Assessments on tinnitus after treatment appeared to have improved significantly regardless of the severity of tinnitus, level of depression or anxiety disorder.

A tumorigenic cell line (BHP10-3M) of PTC showed higher expression of CXCR4 quantitatively and functionally than a nontumorigenic cell line (BHP10-3). The CXCR4 antagonist (AMD3100) showed a significant antitumor effect on the tumorigenic cell line of PTC BHP10-3 cells both in vitro and in vivo. CXCR4 antagonist can be expected to have an adjuvant role in the management of PTC. © 2016 Wiley Periodicals, Inc. Head Neck, 2016 © 2016 Wiley Periodicals, Inc. Head Neck 38: First-1486, 2016.
