Objective: Increasing number of patients are developing complicated pleural infection. We aimed at revealing the differences of treatment modalities performed in patients with empyema. Methods: Patients those had been diagnosed and treated for empyema were assessed in a retrospective design. For the definitive diagnosis of empyema, thoracentesis was made. We categorized the patients in two groups as therapeutic drainage (group 1) and open surgery (group 2). Results: A total of 360 patients, 57 of whom were women, were included. Tube drainage was applied to the patients in group 1, and therapeutic thoracentesis was applied to those not suitable for drainage. Patients who did not provide adequate drainage due to loculation were deloculated with fibrinolytic agent or video-assisted thoracoscopic surgery. In patients with advanced empyema with multiloculation and remarkable pleural thickening, which constituted group 2, decortication was performed by thoracotomy. Thoracoplasty was added in those who had insufficient lung volume. There were 292 (81.2%) patients in group-1 and 68 (18.8%) patients in group 2. In comparison of two groups, a significant difference was detected for lactate dehydrogenase (p

Introduction: Coronavirus diseases-2019 (COVID-19) have been ongoing for more than two years. Despite the scientific research conducted in this process, there is still no widely accepted definitive treatment for the disease. For treating COVID-19, using antiviral agents previously used for the treatment of other RNA-virus infections has been seen as a fast way to a solution, and favipiravir is one of the leading agents. This prospective, multicenter, observational study was designed to investigate the safety of favipiravir in 500 patients treated with favipravir for favipravir. Methods: This study was conducted as a multicenter prospective study. Eight different sites from four cities participated, and 500 patients were included in the study. Follow-up of laboratory parameters, adverse events (AEs), and amelioration of fever, dyspnea, and cough symptoms of the patients was recorded in a case report form. Results: A total of 475 patients from eight centers completed the study. A total of 401 AEs were reported in 206 (51.4%) patients, which were mild-to-moderate in the majority of cases. Serious AEs occurred in 5 patients and death occurred in 4 patients. From the first to the last measurement, serum alanine aminotransferase levels (31.9±27.7 vs. 47.2±49.7 U/L, p37.8 for 6.6% on day 3, 3.2% on day 5, and 0.6% on day 10), dyspnea (for 56.4% on day 5, 62.4% on day 7, and 81.2% on day 10), and cough (46.0% on day 5, 73.0% on day 7, and 87.3% on day 10) were noted in an increasingly higher percentage of patients with continued therapy. Conclusion: The current study provides real-life data of favipiravir, which is a unique option in Turkey for treating COVID-19 patients. The results revealed that favipiravir is a well-tolerated agent with a low side-effect profile. However, it needs to be evaluated with well-designed, dose-compared, randomized controlled studies for the evaluation of efficacy.

Abstract Objective Risk analysis models, which are used in the diagnostic algorithm of incidental pulmonary nodules, are based on patient data from developed countries. Mayo Clinic, Brock University and Herder are among the most known models. We aim to compare the reliability of these models in patients with indeterminate solid nodules and to investigate the contribution of the predictors used to the model. Methods We analysed 305 patients who performed transthoracic needle biopsy and positron emission tomography/computed tomography for solid nodules, retrospectively. For all three models, the malignancy risk probabilities of patients were calculated, and patients were classified as low (

Objective The purpose of this study was to determine the diagnostic value of pleural fluid lactate dehydrogenase (LDH)/pleural fluid adenosine deaminase (ADA) ratio in differentiating pleural effusions owing to tuberculous pleurisy (TBP) and parapneumonic effusion (PPE). Patients and methods The data of 272 patients (140 patients with TBP and 132 patients with PPE) between January 2012 and October 2018 were analyzed retrospectively. Demographic data of all patients; concurrent serum glucose, albumin, protein, and LDH values; and pleural fluid pH, glucose, albumin, protein, and ADA results have been reviewed. Results Pleural fluid ADA values were statistically significantly higher in the TBP group than PPE (P

Abstract Background The aim of this paper was to evaluate the availability of FRAX for assessing osteoporosis risk, and to demonstrate the importance of vitamin D levels in COPD patients. Methods Fourty-six males who fulfilled the COPD diagnostic criteria defined by GOLD were included. Age, race, BMI, physical activity frequency, smoking and dietary habits, age at COPD diagnosis, disease duration, fractures history, and medications use were determined. Levels of 25(OH)D were detected. BMD was measured by DXA at lumbar spine, femoral neck, and entire femur, and classified according to ISCD. FRAX score was calculated. Control group was composed of 40 non-smoker individuals without previous history of pulmonary diseases. Results 25(OH)D levels were significantly different between patients and controls. In the COPD group, a statistically significant difference in vitamin D levels was detected among the A, B, C, and D grades, while no such significant differences in FRAX scores were detected. 25(OH)D levels were significantly low in COPD patients with disease exacerbations and hospitalizations in the previous one year. No correlation was detected between vitamin D levels and the FRAX score. A positive correlation was observed between vitamin D levels and T-score. FRAX scores were higher and vitamin D levels were lower in osteoporotic COPD patients than in non-osteoporotic COPD patients. Conclusion Using FRAX for assessing osteoporosis in COPD can reduce fracture risk and allow adequate treatment. Since vitamin D levels are related to exacerbations and hospitalizations, vitamin D supplementation may be needed in COPD patients, especially in those with high FRAX scores.

PURPOSE: This study aims to investigate whether there is a significant difference between typical and atypical parenchymal patterns in the development of fibrosis, which is the most crucial factor affecting morbidity in pulmonary sarcoidosis. METHODS: In our hospital, 145 cases with Siltzbach Types 2 and 3 sarcoidoses diagnosed by clinical, radiological, and histopathologic were retrospectively investigated. Perilymphatic nodules, accompanying mosaic attenuation, and interlobular septal thickening and central peribronchovascular bunch-like thickening on high-resolution computed tomography were assessed as typical. Solid nodules, galaxy finding, consolidation, ground-glass opacity, isolated mosaic attenuation, and interlobular septal thickening, and pleural fluid were accepted as atypical findings. Findings indicating fibrosis were fine and rough reticular opacity, traction bronchiectasis, volume loss, and cystic changes. For the analysis of variables, SPSS 25.0 program was used. RESULTS: Ten (16%) of the 61 cases with typical findings and 16 (19%) of the 84 with atypical findings developed fibrosis (P = 0.827). The mean age of cases with fibrosis was higher. With the cut-off of 50 years, sensitivity was 61.5%, and specificity was 68.9%. The highest fibrosis rate was in cases with ground glass pattern (n = 7/17), whereas higher reversibility rates were in those with miliary pattern (n = 9/12) and galaxy sign (n = 5/6). CONCLUSION: The incidence of fibrosis is higher in the atypical group with no significant difference. The incidence of fibrosis differs in each atypical pattern, being highest in ground-glass opacity and lowest in the miliary pattern.

Background The study was planned to investigate the importance of Glasgow prognostic score (GPS) in cases that require hospitalization owing to chronic obstructive pulmonary disease (COPD) acute attack. Patients and methods The study retrospectively conducted 223 patients with acute exacerbation of COPD. Based on the data obtained from the files, the requirement of transfer to intensive care and death in hospital was considered as negative results. Results In total, 233 cases were involved in this study. A total of 194 (83.3%) of the patients were male, and 39 (16.7%) were female. GPS of 0, 1, and 2 were observed in 36, 112, and 85 patients, respectively. Cox regression analysis indicated that hospitalization in ICU (P=0.000, odds ratio: 7.45, confidence interval: 4.77–11.53%) and GPS 2 (P=0.11, odds ratio: 3.34, confidence interval: 1.314–8.52%) are independent risk factors for negative results of acute exacerbation. Survival times were shorter at significant levels in GPS 2 group. Conclusion It was found that elevated GPS values are associated with increased hospital mortality risk. GPS is a universally available, low-cost method and may be used as a prognostic marker for short-term hospital mortality in patients with acute exacerbation of COPD.

Aim: The aim of this study wass to compare the cytological features of pleural exudative fluids by conventional smear (CS) method and cell block (CB) method and also to assess the utility of the combined approach for cytodiagnosis of these effusions. Materials and Methods: In all, 113 pleural exudative fluid samples were subjected to evaluation by both CS and CB methods over a period of 2 years. Cellularity, architecture patterns, morphological features, and yield for malignancy were compared, using the two methods. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for diagnosis of malignancy were calculated for both the methods, using histology as a gold standard. Results: CB method provided higher cellularity, better architectural patterns, and additional yield for malignancy when compared with CS method. For 22 (40%) patients, histologic subtype was determined with CB especially for adenocarcinoma. The sensitivity, specificity, positive, and negative predictive values of cytology and CB were 48%, 100%, 100%, 67.8% and 59.2%, 100%, 100%, 72.8%, respectively. Conclusion: CB technique definitively increased detection of malignancy in pleural fluid effusion when used as an adjunct to CSs. Also, CB provides material suitable for molecular genetic analysis for targeted therapies especially in the treatment of adenocarcinoma.
