Evaluation of disease control after SARS-CoV-2 infection or vaccination in patients with NSAID-exacerbated airway disease.

Background: There are insufficient data on changes in disease control after severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection or vaccination in patients with nonsteroidal anti-inflammatory drug exacerbated respiratory disease (N-ERD). Objective: This study aimed to investigate the history of coronavirus disease 2019 (COVID-19) in patients with N-ERD, determine whether they experienced exacerbations of asthma or rhinitis after COVID-19, and evaluate their postvaccination asthma and rhinitis control data. Methods: The demographic characteristics of patients with N-ERD and whether they had had symptoms of asthma, changes in nasal symptom scores Sino-nasal outcome test (SNOT-22), Asthma Control Test (ACT) within 1 month after SARS-CoV-2 vaccination or infection were recorded. The prevalence of COVID-19 in patients with N-ERD and in healthy controls was estimated. Results: A total of 103 patients with N-ERD and 100 healthy controls were included in the study. Thirty seven of the patients (35.9%) and 65 of the controls (65%) had a history of COVID-19. There were no significant differences in changes in the ACT and SNOT-22 scores after SARS-CoV-2 vaccination (p = 0.999). Although, the change in ACT score after infection was significant (p = 0.017; r = 0.39), there was no significant change in level of asthma control (p < 0.001). Conclusion: The history of COVID-19 was less frequent in the N-ERD group. There was no deterioration in asthma and rhinitis controls after SARS-CoV-2 vaccination. Although a significant decrease was observed in the ACT scores after COVID-19, there was no deterioration in the level of asthma control.

Discrimination of leptomeningeal carcinomatosis and meningeal inflammation/infection with internal acoustic canal enhancement.

PURPOSE: The purpose of this study is to investigate whether the presence and pattern of enhancement at the internal acoustic canal (IAC) could help in discriminating between leptomeningeal carcinomatosis (LCa) and meningeal inflammation/infection (MMI). METHODS: Magnetic resonance (MR) images of patients with leptomeningeal enhancement were retrospectively evaluated. MR images of the LCa group (n = 33), MMI group (n = 19) and control group (n = 33) were evaluated for the presence, type (moderate/prominent), and localization (unilateral/bilateral) of the IAC enhancement. RESULTS: The presence of IAC enhancement was significantly more common in patients with LCa (p < 0.001). In 73.7 % of patients with MMI, no contrast enhancement was observed in the IAC. In patients with contrast enhancement in the IAC, the risk of LCa in the etiology is 20 times greater than the risk of having MMI. Seventy-five percent of the IAC enhancement seen in LCa patients and 20 % of the IAC enhancements seen in MMI patients was bilateral. This difference was statistically significant (p = 0.029). CONCLUSION: Intense contrast enhancement of the IAC can be a marker for LCa.

Effect of Pulmonary Functions on Survival in Patients with Operable Non-small Cell Lung Cancer.

OBJECTIVE: To investigate the prognostic importance of pulmonary functions and their effect on survival in patients with operable non-small cell lung cancer (NSCLC), who underwent surgical resection and/or received medical treatment. STUDY DESIGN: Cohort study. PLACE AND DURATION OF STUDY: University of Health Sciences, Diskapi Training and Research Hospital, Ankara, Turkey, between June 2013 and March 2020. METHODOLOGY: The study included a total of 70 patients diagnosed with non-small cell lung cancer (NSCLC), comprising 35 who underwent surgical treatment and 35 who were treated medically. The effects of age, gender, additional comorbidities, smoking status, complications after surgery and/or radiotherapy, and pulmonary function test values ​​on survival were investigated. RESULTS:  The median overall survival time of the patients was 1973±769.1 (466-3.480) days. According to the univariate Cox regression analysis, the preoperative and postoperative values of the forced expiratory volume in 1 second were not important risk factors affecting survival (p=0.752 and p=0.878) respectively. A statistically significant difference was observed in survival probability between the patients with and without coronary artery disease (CAD) (p=0.005). There was also a statistically significant difference between the Eastern Cooperative Oncology Group (ECOG) performance groups in terms of survival probability (p<0.001). CONCLUSION: There was no relationship between pulmonary functions and survival in patients with operable NSCLC, but this evaluation should be undertaken in larger patient groups. This study demonstrated the importance of patients' performance status and comorbidities, such as CAD in survival. KEY WORDS: Non-small cell lung cancer, Survival, Respiratory function test.
