RESUMO
INTRODUCTION: YKL-40 is a glycoprotein that plays role in inflammation and malignant processes. High serum YKL-40 levels are associated with short survive in cancer and chronic obstructive pulmonary disease (COPD) is another reason to increase its' level. However, limited knowledges are known in YKL-40 along with lung cancer and COPD. MATERIALS AND METHODS: One hundred patients were involved to study with lung cancer (84 men, 16 women, and median age 62). Results were compared with 30 healthy volunteers. Thirteen patients were small cell lung cancer (SCLC), 87 patients were non-small cell lung cancer (NSCLC). 62% of patients were inoperable. RESULT: Median YKL-40 level was 222.7 ± 114.1 ng/mL in patients and was 144.5 ± 105.7 ng/mL in controls (p< 0.001). Stage, tumour size, lymph node involvement and distant metastasis weren't associated with serum YKL-40 level. Above all cut-off values (133.159 and 162 ng/mL) survival was shorter (p> 0.05). Patients with COPD had worse survive above all cut-off values (p< 0.05), especially according to 133 ng/mL (p= 0.01). CONCLUSIONS: YKL-40 level is useful in lung cancer however it's not related to cell type and prognosis. It is associated with poor prognosis in lung cancer patients with COPD.

PURPOSE: The first disease-specific quality-of-life questionnaire in patients with drug hypersensitivity, Drug Hypersensitivity Quality of Life Questionnaire (DrHy-Q), was developed and validated recently. The aim of this study was to assess validity, reliability and responsiveness to interventions of the Turkish version of the DrHy-Q. METHODS: The Turkish version of the DrHy-Q was administered to prospectively enrolled 736 patients with drug hypersensitivity from ten allergy units. To assess validity, all patients completed the validated Turkish version of Psychological General Well-Being Index (PGWBI). For test-retest reliability, 182 patients completed the DrHy-Q 1 week after the first questionnaire administration without any intervention. Responsiveness was assessed on 97 patients who had a DrHy-Q recorded at a follow-up visit after the intervention. RESULTS: The internal consistency and test-retest reliability of the scale were adequate (Cronbach's alpha = 0.934, intra-class correlation coefficient = 0.783). The DrHy-Q scores showed weak negative correlations with the PGWBI total and domain scores (r = - 0.378 to -0.254, p < 0.001). DrHy-Q was able to discriminate the patients with one drug hypersensitivity reaction from the patients with two and above two reactions (p = 0.012 and p < 0.001, respectively), and the patients who experienced a respiratory reaction from the patients who did not (p = 0.018). However, it did not discriminate the patients with comorbid disease including psychiatric comorbidity (p > 0.05). The baseline DrHy-Q scores were significantly higher than the post-intervention scores (p = 0.008). CONCLUSION: The Turkish version of DrHy-Q is reliable and valid for evaluating quality of life in patients with drug hypersensitivity, and it appeared responsive to interventions.

INTRODUCTION: Vascular endothelial growth factor (VEGF) and Angiopoietin-2 (Ang-2) are major angiogenic mediators in neovascularization process. In current literature both biomarkers are discussed separately and only for non-small cell lung cancer (NSCLC). So in this study we aimed to examine them together for both cell types NSCLC and small cell lung cancer (SCLC). PATIENTS AND METHODS: 100 patients with lung cancer were enrolled to this single center study. 87 of patients were diagnosed with NSCLC including 28 adenocarcinomas and 59 squamous cell cancers and 13 were SCLC. Results were compared with 30 healthy volunteers. Pre-treatment serum VEGF and Ang-2 levels were measured by using ELISA method. RESULTS: While serum Ang-2 levels were higher in patients than healthy controls (23395 pg/mL vs. 4025 pg/mL, p< 0.001), VEGF levels didn't differ (2308 pg/mL vs. 2433 pg/mL, p> 0.05). There was no difference between cases with SCLC and NSCLC in terms of Ang-2. But serum VEGF values were significantly lower in SCLC than NSCLC and control groups. None of these mediators were correlated with cell type, tumor size, TNM staging, performance status and operability. VEGF levels were higher in patients with chronic obstructive pulmonary disease (COPD), but it was not significant. Three cut of values were determined according to sensitivity and specificity by using youden index. They were 8515.73 pg/mL (sensitivity 78%, specificity 76%), 7097 pg/mL (sensitivity 80%, specificity 70%) and 11063.48 pg/mL (sensitivity 76%, specificity 70%). Patients with SCLC had shorter survival time above cut-off values (p> 0.05). VEGF and Ang-2 showed a weak positive correlation (p= 0.1 and r= 0.638). CONCLUSION: In conclusion, serum VEGF wasn't useful to predict lung cancer, prognosis or cell type. Albeit Ang-2 was higher in patients with lung cancer without any effect on survival. Due to the heterogeneity of the studies done with serum measurement Ang-2 on tumor tissue should be more meaningful.

Although bleeding is the most serious complication of oral anticoagulant treatment, hemothorax is extremely rare. Herein, a case with localized pleural plaques and spontaneous hemothorax due to warfarin treatment which was improved with medical treatment is presented because of its rarity. The patients recieving oral anticoagulant treatment should be monitorized for effective anticoagulation and adverse effects, if pleural effusion occurs, hemothorax should be kept in mind in the differential diagnosis. Pleural pathologies such as pleural plaques or thickening may be risk factors for hemothorax.
