Abstract
BACKGROUND Pulmonary thromboembolism (PE) is a major disease in respiratory emergencies. Thoracic CT angiography (CTA) is an important method of visualizing PE. Because of the high radiation and contrast exposure, the method should be performed selectively in patients in whom PE is suspected. OBJECTIVES The aim of the study was to identify the role of clinical scoring systems utilizing CTA results to diagnose PE. MATERIAL AND METHODS The study investigated 196 patients referred to the hospital emergency service in whom PE was suspected and CTA performed. They were evaluated by empirical, Wells, Geneva and Miniati assessments and classified as low, intermediate and high clinical probability. They were also classified according to serum D-dimer levels. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated and evaluated according to CTA findings. RESULTS Empirical scoring was found to have the highest sensitivity, while the Wells system had the highest specificity. When low D-dimer levels and "low probabilty" were evaluated together for each scoring system, the sensitivity was found to be 100% for all methods. Wells scoring with a cut-off score of 4 had the highest specificity (56.1%). CONCLUSIONS Clinical scoring systems may be guides for patients in whom PE is suspected in the emergency department. The empirical and Wells scoring systems are effective methods for patient selection. Adding evaluation of D-dimer serum levels to the clinical scores could identify patients in whom CTA should be performed. Since CTA can only be used conservatively, the use of clinical scoring systems in conjunction with D-dimer levels can be a useful guide for patient selection.

Abstract
OBJECTIVE To determine the effects of methyl palmitate on murine model of chronic asthma. METHODS The experimental study was conducted in the animal laboratory of DokuzEylul University, Turkey, from October to December, 2012, and comprised BALB/c mice whowere divided into four equal groups: three experimental and one control group. All groups except the control group were sensitised and challenged with ovalbumin. Mice with experimentally-induced asthma in Group I received saline; Group II dexamethasone 1mg/kg; Group III methyl palmitate300mg/kg intraperitoneally three times per week in the last four weeks of the study period. Animals were sacrificed 24h after the last administration of study drugs. Histological findings of airways were evaluated by light microscopic examination. Blood samples from vena cava inferior were taken for measurement of interleukin-5 levels. SPSS 15 was used for statistical analysis. RESULTS The 28 female mice in the study were divided into 4 groups of 7(25%) each. The age range of the animals was 6-8weeks, and the weight range was 18-20g. All histological parameters and interleukin-5 levels of asthma in the Group III were significantly ameliorated compared to the Group I (p<0.05). All histological parameters and interleukin-5 levels were similar between Group III and Group II. CONCLUSIONS Methyl palmitate exhibited anti-inflammatory effects by resolving the histological changes and reducing the interleukin-5 levels in murine model of chronic asthma.

Abstract
AIM To investigate the effectiveness of indirect computed tomography (CT) venography applied after pulmonary CT angiography to patients with suspected pulmonary embolism. MATERIAL AND METHODS The study comprised 80 patients at high/moderate risk of pulmonary embolism (PE) according to the clinical findings. Computed tomography venography (CTV) was performed 3-3.5 minutes after taking pulmonary CTA images. Color Doppler ultrasonography (CDUS) of the lower extremities was applied to all patients before pulmonary CTA or within 24 hours after CTA. RESULTS Pulmonary embolism was determined in a total of 19 patients (23%). Six patients had deep venous thrombosis on CTV examination even though the CDUS findings were normal. Accepting color Doppler ultrasonography findings as the gold standard, the sensitivity of CTV in determining deep vein thrombosis (DVT) was found to be 100%, specificity 91%, positive predictive value 60%, negative predictive value 100%, likelihood of giving a positive result 11.1, and likelihood of giving a negative result 0. There was a statistically significant good degree of correlation between the two methods (r = 0.741, p < 0.001). CONCLUSIONS Computed tomography venography examination applied after pulmonary CTA is a fast imaging technique that has high diagnostic value and can be an alternative to CDUS, especially when CDUS is insufficient in application and evaluation.

Abstract
Introduction Malignant pleural mesothelioma (MPM) is a malignant of mesodermal neoplasm and arises from multipotential mesothelial or subserosal cells of the pleura, pericardium and peritoneum. Case A seventy five year-old male patient was admitted with chest and lower limb pain. He was a heavy smoker and exposed to environmental asbestos in his childhood. PET-CT scans showed multiple pathological FDG uptakes in lungs and other organs. Biopsies performed from lung and anterior thigh muscles were reported as epitheloid type malignant pleural mesothelioma. Discussion We emphasize that unexpected distant metastases can be observed in MPM and occasionally primary diagnosis can be determined by the biopsy of the metastatic regions. This case also points out the role of PET-CT in the staging of malign mesothelioma by determining different metastatic sites.

Abstract
INTRODUCTION There is very few data on the epidemiological features of interstitial lung diseases (ILD) in the literature. These studies on this subject suffer from limited number of patients. OBJECTIVE The goal of this study was to evaluate the epidemiological features of ILD in Turkey. METHODS Fifty-four investigators, 31 centres in 19 cities from six regions of Turkey, participated in the study. Two thousand two hundred forty-five newly diagnosed patients (51.8% females), led by Turkish Thoracic Society Clinical Problems Study Group, enrolled in this prospective study. RESULTS The mean age was 51.8 ± 16.7 years. The mean age among males was 50.5 ± 18.6 years and 53.0 ± 14.6 years among females (P < 0.001). 23.8% of the cases had ILD with known causes, while 39.4% were in granulomatous group, 23.7% were idiopathic, and 4.4% were in the unclassified group. Overall, histopathologically confirmed diagnosis rate was 40.4%. Sarcoidosis was the most common disease (37%), whereas cases with idiopathic pulmonary fibrosis (IPF) constituted 19,9% of patients. 53% of the sarcoidosis patients were females, and the ratio reaches to 75% under 50 years of age (for this group, IPF ratio is %3). In contrast, sarcoidosis and IPF ratios were equal in males (25%). Sarcoidosis was 8% in men over 50, while IPF was %45. CONCLUSION The overall incidence of ILD in Turkey was computed to be 25.8/100,000.

Abstract
OBJECTIVE To discuss the utility of Sit-to-Stand Test (STST) compared to the 6min walking test (6MWT) for the evaluation of functional status in patients with chronic obstructive pulmonary disease (COPD). MATERIAL-METHOD SUBJECTS Fifty-three patients with stable COPD (mean forced expiratory volume in 1s (FEV(1)) 46+/-9% predicted, mean age 71+/-12 year) and 15 healthy individuals (mean FEV(1) 101+/-13% predicted and mean age 63+/-8) were included. INTERVENTIONS Functional performance was evaluated by STST and 6MWT. During the tests, severity of dyspnea (by Modified Borg Scale), heart rate, pulsed oxygen saturation (SpO(2), by Modified Borg Scale) (by pulse oxymeter), blood pressure were measured. The pulmonary function (by spirometry), quadriceps femoris muscle strength (by manual muscle test) and quality of life (by Nottingham Health Profile Survey) were evaluated. RESULTS The STST and 6MWT results were lower in COPD group than the healthy group (P<0.05). During the 6MWT the rise in the heart rate, systolic blood pressure and the decrease in SpO(2) were statistically significant according to STST in COPD groups (P<0.05). The STST and 6MWT were strongly correlated with each other in both groups (P<0.05). Similarly, they were correlated with age, quality of life, peripheral muscle strength and dyspnea severity in COPD groups (P<0.05). CONCLUSION Similar to 6MWT, STST is also able to determine the functional state correctly. Additionally, it produces less hemodynamical stress compared to the 6MWT. In conclusion, STST can be used as an alternative of the 6MWT in patients with COPD.

Abstract
OBJECTIVE Cisplatin-gemcitabine (PG) and cisplatin-etoposide (PE) combinations are active regimens for non-small cell lung cancer (NSCLC). The present study aimed to compare PG with PE in the treatment of patients with stage IIIB and IV NSCLC. METHODOLOGY We conducted a prospective, multicentre trial. A total of 166 patients were enrolled into the study and received either gemcitabine (1,000 mg/m(2)) on days 1, 8 and 15 plus cisplatin (80 mg/m(2)) on day 2 every 4 weeks, or etoposide (100 mg/m(2)) on days 1, 2 and 3 plus cisplatin (80 mg/m(2)) on day 1 every 3 weeks. RESULTS The overall response rate was superior in the PG group (54.8%vs 39.0%, P=0.045). There was no significant difference in survival between the two groups, with respective median and 1-year survival of 38 weeks and 33.3% for the PG group, and 34 weeks and 23.2% for the PE group. There was also no statistical difference for time to progression between the two groups. Neutropenia and thrombocytopenia were seen more frequently in the PG group (grade 3 neutropenia, 33.3%vs 15.9%, P=0.012; grade 3 thrombocytopenia, 27.4%vs 3.7%, P<0.001 and grade 4 thrombocytopenia, 10.7%vs 1.2%, P=0.018). CONCLUSION PG is an active chemotherapy regimen and has a better response rate than PE in advanced NSCLC, although there was no difference in time to progression and overall survival. A higher incidence of haematological toxicity was seen with PG than with PE.

Abstract
AIM The aim of this study was to correlate findings of perfusion magnetic resonance imaging (MRI) and perfusion scintigraphy in cases where there was a suspicion of abnormal pulmonary vasculature, and to evaluate the usefulness of MRI in the detection of perfusion deficits of the lung. METHODS In all, 17 patients with suspected abnormality of the pulmonary vasculature underwent dynamic contrast-enhanced MRI. T1-weighted 3D fast-field echo pulse sequences were obtained (TR/TE 3.3/1.58 ms; flip angle 30 degrees; slice thickness 12 to 15 mm). The dynamic study was acquired in the coronal plane following administration of 0.1 mmol/kg gadopentetate dimeglumine. A total of 8 to 10 sections repeated 20 to 25 times at intervals of 1s were performed. Perfusion lung scintigraphy was carried out a maximum of 48 h before the MR examination in all cases. Two radiologists, who were blinded to the clinical data and results of other imaging methods, reviewed all coronal sections. MR perfusion images were independently assessed in terms of segmental or lobar perfusion defects in the 85 lobes of the 17 individuals, and the findings were compared with the results of scintigraphy. RESULTS Of the 17 patients, 8 were found to have pulmonary emboli, 2 chronic obstructive pulmonary disease with emphysema, 2 bullous emphysema, 2 Takayasu arteritis and 1 had a hypoplastic pulmonary artery. Pulmonary perfusion was completely normal in 2 cases. In 35 lobes, perfusion defects were detected using both methods, in 4 with MR alone and in 9 only with scintigraphy. There was good agreement between MRI and scintigraphy findings (kappa=0.695). CONCLUSION Pulmonary perfusion MRI is a new alternative to scintigraphy in the evaluation of pulmonary perfusion for various lung disorders. In addition, this technique allows measurement and quantification of pulmonary perfusion abnormalities.

Abstract
BACKGROUND Lung cancer is the most common neoplasm in Turkey, but there is not enough data on the characteristics of this mortal illness in our country. OBJECTIVES AND METHODS The Turkish Thoracic Society, Lung and Pleural Malignancies Study Group (TTS-LPMSG) conducted a national retrospective hospital-based study to determine the pattern of lung cancer in Turkey. RESULTS A total of 11,849 lung cancer patients were studied between 1994 and 1998, 90.4% were male and 9.6% were female. The majority of patients were smokers (77.9%) or ex-smokers (10.8%). The mean age at the time of diagnosis was 58.4 years (20-84) and 56.7% of the patients were aged between 46 and 65 years. The most common histological types were squamous cell (45.4%), small cell (SCLC; 20.5%) and adenocarcinoma (20.2%). The majority of patients with non-small-cell lung cancer were diagnosed with metastatic disease (40.4%). Of the patients with SCLC patients, 37.9% had limited stage disease and 62.7% extensive stage disease at diagnosis. CONCLUSION The results of the largest data so far collected in Turkey show that the vast majority of patients with lung cancer are male, squamous cell is the most common histological type, and only a small proportion of patients are diagnosed at an early stage.

Abstract
UNLABELLED Technetium-99m-tetrofosmin, an agent that is widely used in myocardial imaging, has been reported to accumulate in several types of malignancies, including lung tumors. Yet, there is limited knowledge about its role in imaging infection or inflammatory lesions. The aim of this study was to investigate the role of 99mTc-tetrofosmin scintigraphy in pulmonary tuberculosis in cases with active and inactive tuberculosis in comparison with radiological and microbiological findings. METHODS Twenty-seven patients with active pulmonary tuberculosis (APTB) and 6 patients with inactive pulmonary tuberculosis (IPTB), proven by sputum smears and cultures, were included in this study. Mean age of the group was 42.6+/-13 yr. Nine months after therapy, 99mTc-tetrofosmin scintigraphy was repeated in 6 patients with APTB to evaluate response to therapy. Ten-minute anterior and posterior chest images were acquired 20 and 60 min after the injection of 370 MBq (10 mCi) 99mTc-tetrofosmin. The images were evaluated both visually and semiquantitatively by two blinded nuclear medicine physicians. For semiquantitative evaluation, regions of interest (ROIs) were drawn over the lesion (L) and nonlesion areas (NL). The mean count values of ROIs were obtained and L/NL ratios were calculated. RESULTS According to the visual evaluations, 99mTc-tetrofosmin uptake was Grade (+) in 4 (15%) and Grade (++) in 23 (85%) patients with APTB. Technetium-99m-tetrofosmin uptake was negative in 5 patients with IPTB. Grade (+) 99mTc-tetrofosmin uptake was observed in only one inactive case. After therapy, there was no 99mTc-tetrofosmin uptake in 3 patients, which correlated well with chest radiography and clinical findings. In the other 2 patients, 99mTc-tetrofosmin uptake was slightly decreased when compared with a previous scan that correlated with radiological and clinical findings. In 1 patient with bilateral lung disease, 99mTc-tetrofosmin uptake decreased on the right lung lesions, whereas the left lung lesions persisted with no change. The mean early and delayed L/NL ratios of APTB were 1.53+/-0.22 and 1.45+/-0.21, respectively. Although 99mTc-tetrofosmin uptake in APTB lesions was more visually marked in early images than that in delayed images, there was no statistically significant difference between these two sets of images. CONCLUSION Technetium-99m-tetrofosmin scintigraphy showed increased uptake in APTB lesions related to disease activity. After treatment, 99mTc-tetrofosmin uptake disappeared or decreased, correlating well with radiological and clinical findings. Technetium-99m-tetrofosmin scintigraphy may have a complementary role in the assessment of APTB as well as in follow-up treatment.

Abstract
Theophylline and benzodiazepines are frequently combined in clinical practice. Because of a number of case reports about antagonism of benzodiazepine-induced sedation by theophylline, we investigated serum alprazolam levels in a convenient sample of pulmonary medicine inpatients receiving theophylline and no theophylline. One mg of alprazolam was given daily for seven days to 6 patients receiving theophylline and 7 patients not receiving theophylline treatment. On days 2 through 7, trough serum alprazolam levels were measured. On day 7, blood samples were collected before (0 hour), and at 3, 6, 9 and 12 hours after alprazolam administration. In patients receiving theophylline, serum trough alprazolam levels were significantly lower during each day of the study. In patients receiving no theophylline, serum alprazolam levels were in the therapeutic range, except for two patients who had high alprazolam levels. In this small study, serum alprazolam levels were found to be consistently below the therapeutic range in patients receiving chronic theophylline treatment. Previously reported antagonism of anxiolytic effects of benzodiazepines by theophylline is probably due to the lower serum benzodiazepine levels in these patients.

Abstract
Children who had undergone adenotonsillectomy for recurrent adenotonsillitis showing no signs of clinical or radiological obstructive manifestations were evaluated with pulmonary function tests before, and one month after the operation. In relation to the result obtained by function tests, 60% of 45 cases (27) had the findings of mild obstructive pulmonary disease whereby these findings were in transient character that vanished after the operation. The following parameters were measured and found that they were all increased, mean FVC from 82.22 +/- 6.82 to 93.11 +/- 7.81 (p < 0.01), mean PEF from 77.60 +/- 8.38 to 88.60 +/- 5.57 (P < 0.01), mean FEVI from 74.28 +/- 11.68 to 90.15 +/- 7.28 (p < 0.01), mean FEF 25 from 71.44 +/- 11.53 to 83.53 +/- 6.40 (p < 0.01), mean FEF 50 from 69.53 +/- 14.53 to 84.37 +/- 7.72 (p < 0.01), mean FEF 75 from 70.08 +/- 12.15 to 85.48 +/- 7.15 (p < 0.01). In conclusion, pulmonary function tests could reveal the obstructive effects of adenotonsillar hypertrophy with no clinical or radiological obstructive findings, and could be useful in surgical indications of adenotonsillar hypertrophy dur to recurrent infections in children.
