Evaluation of the Effect of Sampling Strategy on Test Results in the COVID-19 Pandemic.

BACKGROUND: The oronasopharyngeal (ONP) sampling phase is critical in the diagnosis of infection during the coronavirus disease-2019 (COVID-19) pandemic. In this study, the aim is to investigate the effect of the standardized operational team in the sampling unit on test results and repetitions. METHODS: Patients who applied to the Adult Pandemic Polyclinic between August 2020 and October 2021 and whose ONP samples were taken for Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) Polymerase Chain Reaction (PCR) test were included in the study. For August 2020, the Ear, Nose and Throat (ENT) specialists were appointed to work in the sample collection unit. For the following months, physicians from other clinics as well as ENT specialists were appointed under the same conditions. The ENT and other specialties were compared in terms of PCR positivity and test repetition. RESULTS: Out of a total of 129,808 patients, 21,602 (16.6%) of them were sampled by ENT physicians, and 108,206 (83.4%) by others. The first three months with the highest number of ONP samples were August 2021 (n: 20,317; 15.7%), July 2021 (n: 11,767; 9.1%), and November 2020 (n: 11,511; 8.9%). The highest positive PCR results were in August 2021 followed by August 2021 (37.3%), December 2020 (32.8%), and November 2020 (32.5%). In September 2020, more positive results were obtained from the samples taken by ENT specialists (p = 0.001). The repetition frequency of ONP samples taken by ENT and other specialists was calculated as 221 (1%) and 878 (0.8%), respectively (p > 0.05), and the month with the highest re-test rate was November 2020. CONCLUSIONS: It is seen that the training of ENT specialists given to non-ENT specialists on sampling technique is effective and the process is managed with optimal benefit. This study can be evaluated as the first step data in comparing all these organizations and emphasizing the importance of the cooperation created by the institutions during the pandemic process.

Effects of platelet-rich fibrin and dexamethasone on nerve regeneration after acute facial-nerve injury.

BACKGROUND: Acute facial-nerve injury. OBJECTIVE: To investigate the effects of platelet-rich fibrin (PRF) and dexamethasone on nerve regeneration. MATERIALS AND METHODS: Thirty-six rats were randomly divided into six groups. Facial-nerve injury was created using a full-thickness incision in all groups except Group E. Next, primary anastomosis, PRF application, topical dexamethasone application, primary anastomosis with topical PRF and dexamethasone application, and no facial-nerve repair were performed in Groups A, B, C, D, and F, respectively. Clinical, functional, and structural improvements were evaluated at eight weeks. RESULTS: The mean eye-closure movement score in Group B was significantly higher than that in Group F (p < .001). The mean whisker-movement score in Group B was significantly higher than that in Group F (p = .001). The mean amplitude of whisker movement in Group F was significantly lower than those in Groups A, B, C, and E, and the mean amplitude in Group D was significantly lower than that in Group E (p < .001). Furthermore, an improvement in nerve ultrastructure was observed in Group B. CONCLUSION: PRF application has a positive effect on nerve recovery after anastomosis. SIGNIFICANCE: Contribute to the literature to improve nerve regeneration.

Does the Change in the Indications of Endoscopic Sinonasal Surgery Continue? Data between 1994-2018.

OBJECTIVE: Endoscopic sinonasal surgery (ESS) has changing over the years in parallel with the developments in endoscopy devices, video-imaging techniques, and surgical instruments. In the present study we investigated whether the indications of patients who underwent surgery over a period of 25 years have accommodated to these changes. METHODS: We retrospectively evaluated 1173 patients who underwent surgery in our clinic from 1994 through 2007, and 954 patients who underwent surgery from 2008 through 2018. The patients were divided into three groups as follows: chronic rhinosinusitis with polyps (CRSwNP), chronic rhinosinusitis without polyps (CRSsNP), and others. The changes in the indications during the first 14 years and the following 11 years were compared, and the results were statistically evaluated. RESULTS: A significant decrease was observed in the number of patients who underwent surgery following the diagnosis of CRSsNP (p<0.001). In addition, a statistically significant increase was found in CRSwNP (p<0.001) and other (p<0.001) indications. CONCLUSION: When ESS indications identified in our clinic were reviewed, it was observed that the increasing trend in CRSwNP rate in the first 14 years continued, there was a significant increase in non-CRS indications in the last 11 years, and there has been an increase in patients with fungal sinusitis, especially in this group.
