    Assessment of liver hydatid cyst cases - 10 years experience inTurkey
    (2007) Mergen H.; Genç H.; Tavusbay C.
    We analysed 73 hydatid cyst patients according to their age, gender, localization, number of cysts, infectivity, symptoms, physical examination findings, presence of accompanying diseases, and diagnostic methods. Female/male ratio was 1.6/1. In total, 69% of cases had a single cyst and 31% multiple cysts. Of the cysts, 61% were in form of 'eau de roche' and the rest infective. The mean age was 42.3 years, ranging from 18 to 85 years. The most common symptom was abdominal pain in 74% of patients. Right lobe involvement was encountered in 65% of cases, left lobe in 13%, and left and right in 8%. In 27% of patients, cholelithiasis was the most common accompanying disease. As an imaging technique ultrasound was the most commonly used diagnostic technique. © 2007, Royal Society of Medicine Press. All rights reserved.

    Acute phase reactants in patients with coronary slow flow phenomenon; [Koroner yavaş akım fenomeni olan hastalarda akut faz reaktanları]
    (AVES, 2010) Madak N.; Nazli Y.; Mergen H.; Aysel S.; Kandaz M.; Yanik E.; Çekdemir D.; Tavli T.
    Objective: In this study, we sought to investigate the serum levels of high sensitivity C-reactive protein (Hs-CRP), N-terminal pro-brain natriuretic peptide (NT proBNP), erythrocyte sedimentation rate, leukocyte, thyroid hormone and fibrinogen levels in patients with coronary slow flow phenomenon (CSFP). Methods: A total of 82 patients with angiographically proven normal coronary arteries and slow coronary flow in all three coronary vessels (45 males and 37 females, mean age 59±11 years) and 34 patients with normal coronary arteries and normal coronary flow (19 males and 15 females, mean age 56±10 years) with similar risk profiles were included in this cross-sectional observational study. Coronary flow rates of all patients and control subjects were documented by Thrombolysis In Myocardial Infarction (TIMI) frame count, serum level of Hs-CRP, NT proBNP, sedimentation, leukocyte, free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH) and fibrinogen levels were measured. Statistical analysis was performed using t test for independent samples, Chi-square test and Pearson correlation analysis. Results: Hs-CRP (0.88±0.86 vs 0.36±0.35 mg/L, p<0.001) and NT proBNP (117.83±163.2 vs 47.33±30.6 ng/ml, p<0.01) were found to be significantly higher in patients with coronary slow flow compared with normal control group. There are no significant differences regarding thyroid hormones, fibrinogen, sedimentation and leukocyte between two groups. The mean TIMI frame counts were positively correlated (r=0.454, p=0.001 and r=0.554, p=0.001, respectively) with plasma Hs-CRP levels and NT-proBNP levels. Conclusion: Hs-CRP and NT proBNP are significantly higher in patients with coronary slow flow compared with normal control group. Their increased levels are positively correlated with TIMI frame count. © 2010 by AVES Yayi{dotless}li{dotless}k Ltd.

    Comparative validity and reliability study of the QIDS-SR16 in Turkish and American college student samples; [Türk ve amerikalı üniversite öǧrencilerinde hızlı depresif belirti envanteri-özbildirim formu'nun (HDBE16-ÖF) karşılaştırmalı olarak geçerlik ve güvenirliǧi]
    (Cukurova Univ Tip Fakultesi Psikiyatri Anabilim Dali, 2011) Mergen H.; Bernstein I.H.; Tavli V.; Ongel K.; Tavli T.; Tan S.
    Comparative validity and reliability study of the QIDS-SR16 in Turkish and American college student samples Objective: To evaluate the validity and reliability of the Quick Inventory of Depressive Symptomatology, selfreported version, in a Turkish student sample (QIDS-SR16-T) by comparing it to (a) the American version (QIDS-SR16- US) and (b) the Turkish version of the Beck Depression Inventory (BDI-II-T). Materials and Methods: Slightly modified versions of the QIDS-SR16-T, and the BDI-II-T were administered to 626 outpatients at the Uludaǧ University campus-based family health center. The QIDS-SR16-US was administered to 584 respondents at an American university. SAS and MPlus were used to provide descriptive statistics, classical exploratory factor analysis, and item response theory analyses (in the form of a multiple group confirmatory factor analysis). Results: The internal consistency (Cronbach α) of the QIDS-SR16-T was 0.77. Both QIDS-SR16 versions were unidimensional, but the BDI-II-T was not. The mean QIDSSR16- T and QIDS-SR16-US item-total correlations were similar. The correlation between the QIDS-SR16-T and BDIII- T was 0.72 (.90 when disattenuated). Multiple-group confirmatory factor analysis suggested that the QIDSSR16- T and QIDS-SR16-US had the same factor loadings but different intercepts. This reflects group differences in level of depression, perhaps because the Turkish respondents, unlike their US counterparts, were seen in a medical context where illness-related depression is more prevalent. Scores on the QIDS-SR16-T and the BDI-II-T were also equated. Discussion: The QIDS-SR16-T has good psychometric properties and convergent validity with the BDI-II-T. Its use is recommended when a self-reported instrument is appropriate.

    Validity and reliability of the QIDS-SR16-Turkish in comparison with BDI-IITurkish among young outpatient sample of Turkish University students; [Hızlı Depresif Belirti Envanteri-Özbildirim Formu'nun (HDBE 16 -ÖF) Beck Depresyon Envanteri-II ile Karşılaştırılarak Ayaktan Başvuran Hastalarda Geçerlilik ve Güvenilirliǧi]
    (Turkish Neuropsychiatric Society, 2012) Mergen H.; Tavli T.; Öngel K.
    Objective: To evaluate the validity and reliability of 16-item self-report version of the Quick Inventory of Depressive Symptomatology (QIDS-SR16) scale in comparison with BDI-II-Turkish (BDI-II-T) in a young sample of Turkish university students. Methods: A slightly modified version of the QIDS-SR16-Turkish (QIDS-SR16-T) available at www.ids-qids.org, along with the BDI-II-T, was administered to 628 young Turkish university students who attended the Family Health Center in Uludaǧ University Campus between February and April 2010. Descriptive analyses, Student's t-test, receiver operating characteristic (ROC) analysis, and confirmatory factor analyses were used in the study. Results: The mean age of the participants was 21.1±2.16 (SD) years; 67.8% were female and 32.2% were male. Cronbach's α coefficient for internal consistency of the QIDS-SR16-T was found to be 0.769. The mean item-total correlation was 0.45, ranging from 0.29 to 0.71. The correlation between the BDI-II-T and QIDS-SR16-T was 0.72. ROC curve analysis suggested 9 as the optimal cut-off for a clinical depression level for the QIDS-SR16-T. Conclusion: We observed that the QIDS-SR16-T demonstrated good psychometric properties in a sample of young Turkish students and has convergent validity with the BDI-II-T, a widely used scale for depression. It is essential to diagnose reliably the major depressive disorder and to follow up the patients by valid screening instruments in primary care setting. The internal consistencies of the QIDS determined in studies from the United States were greater than our Cronbach's α coefficient, but there was no statistically significant difference between them (z=0.55, p>0.05). The QIDS-SR16-T can be reliably used in primary care settings. © Archives of Neuropsychiatry, published by Galenos Publishing.
