RESUMO
INTRODUCTION: The search for biomarkers that could help in predicting disease prognosis in the Coronavirus Disease-2019 (COVID-19) outbreak is still high on the agenda. OBJECTIVE: To find out the efficacy of D-dimer and mean platelet volume (MPV) combination as a prognostic marker in hospitalized COVID-19 patients with bilateral infiltration. MATERIALS AND METHODS: Study design: Retrospective observational cohort. Patients who were presented to our hospital between March 16, 2020 and June 07, 2020 were reviewed retrospectively. The primary outcome of the study was specified as the need for intensive care, while the secondary outcomes were duration of treatment and hospitalization. Receiver operator curve (ROC) analyzes were carried out to assess the efficacy of D-dimer and MPV parameters as prognostic markers. RESULTS: Between the mentioned dates, 575 of 1,564 patients were found to be compatible with COVID-19, and the number of patients who were included in the study was 306. The number of patients who developed the need for intensive care was 40 (13.1%). For serum D-dimer levels in assessing the need for intensive care, the area under the curve (AUC) was found to be 0.707 (95% CI: 0.620-0.794). The AUC for MPV was 0.694 (95% CI: 0.585-0.803), when D-dimer was ≥1.0 mg/L. When patients with a D-dimer level of ≥1.0 mg/L were divided into two groups considering the MPV cut-off value as 8.1, the rate of intensive care transport was found to be significantly higher in patients with an MPV of ≥8.1 fL compared to those with an MPV of <8.1 fL (32.6 vs. 16.0%, p = 0.043). For the prognostic efficacy of the combination of D-dimer ≥ 1.0 mg/L and MPV ≥ 8.1 fL in determining the need for intensive care, following values were determined: sensitivity: 57.7%, specificity: 70.8%, positive predictive value (PPV): 32.0%, negative predictive value (NPV): 84.0%, and accuracy: 63.0%. When D-dimer was ≥1.0, the median duration of treatment in MPV <8.1 and ≥8.1 groups was 5.0 [interquartile range (IQR): 5.0-10.0] days for both groups (p = 0.64). The median length of hospital stay (LOS) was 7.0 (IQR: 5.0-10.5) days in the MPV <8.1 group, while it was 8.5 (IQR: 5.0-16.3) days in the MPV ≥ 8.1 group (p = 0.17). CONCLUSION: In COVID-19 patients with a serum D-dimer level of at least 1.0 mg/L and radiological bilateral infiltration at hospitalization, if the MPV value is ≥8.1, we could predict the need for intensive care with moderate efficacy and a relatively high negative predictive value. However, no correlation could be found between this combined marker and the duration of treatment and the LOS.
RESUMO
INTRODUCTION: Welding produces miscellaneous gases and particles that has various impact on respiratory system and long term exposure may result "welders'lung". The aim of this study is to describe the radiological findings of welders' and make an awereness for welders radilogical findings. MATERIALS AND METHODS: The clinical and radiological findings of welders' who had hospital applications with respiratory symptoms between January 2010-January 2017 were evaluated retrospectively. RESULT: A total of 16 male welders with mean age 37 ± 8 years had the mean duration of welding occupation 12 ± 7 years. The most common symptoms were coughing (87%), sputum production (63%) and dyspnoea (63%).Thirteen welders were working in shipyards and 3 in construction business and other workplaces. Three (19%) patients had rhonchi on physical examination and these patients had decreased FEV1/FVC values below 70% on spirometry. Poorly-defined centrilobular micronodules that were not clearly visible on chest radiographs observed on thorax high resolution computed tomography. Bronchoscopy was performed to 7 patients. Iron-positive pigment granules and ferruginous bodies were revealed in 3 patients' bronchoalveolar lavage. CONCLUSIONS: Welders' chest X-ray deserve a closer look. In pulmonary radiology, there may be radiographical findings ranging from small ill defined nodules to groundglass opacites. Physcians should look more careful to welders' chest X-ray and incase of suspicious findings best can be detected on high HRCT. An awareness for the radiological findings will also reduce interventional procedures in these patients hereby, occupational history must be included in daily practice of physicians.

INTRODUCTION: Tuberculosis drug resistance can be assessed by physicians with different approaches on issues such as the choice of treatment protocol and duration of treatment. MATERIALS AND METHODS: In this study, we aimed to evaluate the treatment regimens and treatment results of patients with non multi-drug resistant tuberculosis (MDR-TB) drug resistance implemented in different chest disease clinics in our hospital. The 167 culture-positive patients with nonMDR-TB drug resistance diagnosed between 2008-2010 were analyzed retrospectively. Patients' age, gender, previous TB treatments, bacteriological cruise, drug resistance patterns and treatment outcomes were analyzed. RESULT: One hundred sixty-seven patients with eligible data were evaluated; there were 117 (70.1%) men and 50 (29.9%) women, mean age was 42.35 (18-90) years, respectively. Among mono drug resistance; H resistance in 75 (44.9%) patients and R resistance in 11 patients was detected. In 19 (11.4%) patients HS resistance was detected as multiple drug resistance. One hudred and twenty-five (74.9%) were new cases. When treatment the results of in all patients evaluated, 136 (81.4%) of the patients achieved treatment success. Sixty-four (51.2%) of the new TB cases treated with "standard treatment protocols for new cases" (2HRZE/4H) and 51 (40.8%) of them treated with "other treatment protocols". Ten (23.8%)of the recurrent TB cases" standard treatment for recurrent cases (2HRZES/HRZE/5HRE) and 9 (21.4%) 33 (19.8%) of them treated with other protocols. The combination of the rthe treatment protocol and descriptive information about the duration of the treatment could not be created as 33 (19.8%) of the cases left without completing their treatment. CONCLUSIONS: As a result of the analysis, patients have completed their treatment, there was no significant difference in treatment outcomes. Patients with Non MDR-TB drug resistance should be monitored well and should be careful in terms of MDR-TB.

OBJECTIVE: Multidrug-resistant tuberculosis still continues to be a major health problem. Adjuvant surgical resection combined with antituberculous drug management is the most favorable treatment modality for patients with multidrug-resistant tuberculosis. In this article we report the results of surgical resections we performed during the years 1993 through 2005. METHODS: We performed 81 lung resections in 79 patients with multidrug-resistant tuberculosis. All these patients had at least 2 months of medical therapy before resection. Bronchial reinforcement was performed in 4 of the 81 operations. We present here the surgical results of the 81 procedures. Because 5 of 79 patients were lost to follow-up, we provide the medical treatment results on 74 of the patients. RESULTS: During this period, we performed 4 completion pneumonectomies, 39 pneumonectomies, 7 lobectomies with segmentectomy, 30 lobectomies, and 1 segmentectomy. Operative mortality was 2.5% (2/81). Bronchopleural fistula developed in 4 (4.9%) cases. Our overall cure rate was 94.5% (70/74). Relapse and treatment failure were 1.3% (1/74) and 1.3% (1/74), respectively. All but 5 patients are still under our follow-up. CONCLUSIONS: Surgical resection of patients with multidrug-resistant tuberculosis combined with chemotherapy provides a favorable outcome. Our results will need to be validated more strongly by using randomized clinical trials that compare surgical resection plus chemotherapy with chemotherapy alone.

The aim of this study was to assess the diagnostic yield of closed pleural brushing (CPBR) in the diagnosis of malignant pleural effusion. Twenty-one adult patients (20 men and 1 woman); aged 62.9 +/- 8.6 were participated to this prospective study. Thoracentesis, CPBR and closed pleural biopsy (CPB) following the brushing were applied to every patient. While CPBR provided diagnosis in 12 (57.1%) of 21 cases, in 3 of these 12 cases, pleural fluid cytology (PFC) and CPB were negative. The sensitivities of PFC, CPBR and CPB in the diagnosis of malignant effusions were 33%, 57% and 52%, respectively. When three procedures were used in combination, the sensitivity increased to 67%. When CPBR is performed in addition to PFC and CPB, the yield of the diagnosis increased 14% additionally. There was no mortality due to these interventions. Complications were chest pain in 3 (14.2%) cases, hypotension in 2 (9.5%) cases, cough in 1 (4.8%) case, pneumothorax in 1 (4.8%) case, and hemothorax in 1 (4.8%) case. In conclusion, CPBR as a safe, simple and well tolerated procedure provides high diagnostic yield in diagnosis of patients with malignant pleural effusion.
