RESUMEN
Aim Comprehensive studies on the coexistence of COVID-19 and pericardial effusion (PEff) are limited. In this study, we investigated the relationship between pneumonia severity and PEff, predisposing factors, and the effect of PEff on clinical prognosis and mortality in COVID-19 patients.Material and methods Between March and November 2020, 5 575 patients were followed up in our pandemic hospital due to COVID-19. 3 794 patients with positive polymerase chain reaction (PCR) test results and thoraxcomputerized tomography (CT) imaging at admission were included in the study. The clinical and demographic characteristics, CT images, hematological and biochemical parameters of these patients were retrospectively examined. Pulmonary involvement of 3794 patients was divided into three groups and its relationship with PEff was investigated retrospectively.Results There were 560 patients who did not have pulmonary involvement, 2 639 patients with pulmonary involvement below 50â%, and 595 patients with 50â% or more pulmonary involvement. As pulmonaryinvolvement or the severity of the disease increased, male gender and advanced age become statistically significant. The mean age of patients with PEff was higher, and PEff was more common in males. Patients with PEff had more comorbid diseases and significantly elevated serum cardiac and inflammatory biomarkers. The need for intensive care and mortality rates were higher in these patients. While the in-hospital mortality rate was 56.9â% in patients with PEff and pulmonary involvement above 50â%, in-hospital mortality rate was 34.4â% in patients with pulmonary involvement above 50â% and without PEff (p<0.001).The presence of PEff during admission for COVID-19 disease, the appearance of PEff or increase in the degree of PEff during follow-up were closely related to mortality and prognosis.Conclusion As the severity of pulmonary involvement or the clinical severity of the disease increased, PEff occurred in patients or the degree of PEff increased. The clinical prognosis of patients presenting with PEff was quite poor, and the frequency of intensive care admissions and mortality were significantly higher. PEff was an important finding in the follow-up and management of patients with COVID-19, and it reflected the clinical prognosis.

BACKGROUND: This study aimed to investigate the role of inflammatory markers in decreasing negative appendectomy rate (NAR) based on their relation with findings of acute appendicitis (AA) on computed tomography (CT). METHODS: Ninety-two patients who underwent CT examination with suspected AA were included. We investigated the relation between CT findings of AA and laboratory inflammatory markers and also performed receiver operating characteristic (ROC) analysis to calculate cut-off values of inflammatory markers and CT findings of AA. Appendectomy cases were re-evaluated considering cut-off values to make the operation decision and NAR was recalculated. Chi-squared test was used to compare the actual and recalculated NAR. RESULTS: Cut-off values of appendiceal diameter, appendiceal wall thickness, and caecal wall thickness were 7.9, 2, and 2.3 mm, respectively, for the diagnosis of AA. Cut-off values of WBC , NLR, and CRP on ROC analysis were 7.47, 4.06 and 13, respectively, for the diagnosis of AA. When the actual and recalculated NAR (21.9% versus 9.1%) were compared, the difference was found to be almost significant (p=0.058). CONCLUSION: Inflammatory markers are not sufficiently powerful on their own to accurately diagnose AA. However, particularly in equivocal cases, proposed cut-off values may be helpful for accurate diagnosis and a lower NAR can be achieved.
