Background:Fine-needle aspiration cytology (FNAC) in the diagnosis of thyroid nodules is an easy and cost-effective method. The increase in malignancy rates of the excised nodules due to the high sensitivity and specificity rates of the FNAC is remarkable.Aim:The aim of this study was to assess the effectiveness of FNAC in the evaluation of thyroid nodules by comparing the results with histopathologic evaluation and comparing the consistency of the results with the literature.Materials and Methods:In this study, 1607 FNACs of 1333 patients which were classified according to the Bethesda system and 126 histopathological evaluations obtained from this group were evaluated. The mean age of the patients was 51.24 (range: 17-89, 17% male and 83% female). The sensitivity, specificity, positive and negative predictive values, and accuracy rates were evaluated.Results:The sensitivity was 87.1% and specificity was 64.6%. The positive and negative predictive value and accuracy rates were 76.1%, 79.5%, and 77.3%, respectively.Conclusions:In our study, the evaluation of thyroid FNAC samples with Bethesda system highly correlated with the results of histopathological diagnosis. However, combination of additional and advanced diagnostic methods such as immunocytochemical studies and molecular pathology techniques enhance the prognostic value of FNAC in patients with atypia of undetermined significance or follicular lesion of undetermined significance, lesions suspicious for malignancy, and suspected follicular neoplasm.

Purpose: To investigate the reproducibility of LIRADS v2014 and contribute to its widespread use in clinical practice.

Aim:This study aims to investigate the general mental health situation, work-related stress and risk factors of health management trainees.Methods:This cross-sectional study was conducted on Health Management Musters students (N=96) in Canakkale Onsekiz Mart University Health Sciences Institute, May-June 2014. A total of 58 students who voluntarily participated in the study were reached (60.42%). Participants completed a 22-question sociodemographic survey form and a 12-item General Health Questionnaire in a face-to-face interview. Data were analyzed using the SPSS software version 20.0.Results:The average age of participants was 36.4±6.2 (Min:24-Max:62) years. Thirty five of the participants were female (60.3%), 23 were male (39.7%). The number of people using cigarettes and alcohol were 23 (39.7%) and 9 (15.8%) respectively. In our study group according to GHQ scale 32 people (55.2%) were in the group at risk of depression. Eighty-six percent of participants reported experiencing work stress. The most frequently reported sources of stress were superiors (56.8%), work itself (41.3%), and work colleagues (25.8%). There was no significant difference between those at risk of depression and those not at risk in terms of gender, marital status, educational level, age, work-related factors (daily work, computer use, duration of sitting at desk), sleep duration, presence of chronic disease, substance use (cigarettes, alcohol), regular exercise, regular meals, fast-food consumption, sufficient family time and vacations (p>0.05).Conclusions:Our study results indicated that majority of participants reported experiencing work stress with more than half at high risk of developing depression. The most reported risk factors were superiors, the work itself and colleagues in the present study. Psychosocial risk factors at work environment should be investigated in terms of psychological, sociological and ergonomics in more detail to reduce the risk of health management trainees experiencing work stress and mental health problems.
