Background: The sensitivities and specificities of interferon-gamma release assays (IGRAs) vary among different population studies, and the data on the routine use of IGRAs are limited. The aim of this study was to evaluate the role of QuantiFERON-TB Gold In-Tube (QFT-GIT) test in the diagnosis of active tuberculosis. Methods: We conducted a prospective study, enrolling 77 patients with suspected pulmonary tuberculosis (TB), at a secondary care teaching hospital in Seoul. Results: In total, 12 (15.6%) patients showed indeterminate results due to positive control failure on the QFT-GIT test. Indeterminate results were significantly associated with the elderly, history of the intensive care unit stay, lymphocytopenia, especially low CD4 count, increased C-reactive protein and decreased protein levels. Of the 77 patients, 44 (57.1%) were diagnosed with active pulmonary tuberculosis, and the percentage of false negative results of the QFT-GIT was 36.4% (vs. 31.8% with TST). In the TB group with >65 years old (n=12), the proportions of the indeterminate (33.3% vs. 3.1%) and the false negative results (58.3% vs. 25.0%) of the QFT-GIT were significantly higher than in the younger TB group (n=32). Conclusion: Indeterminate and false negative results of QFT-GIT test were not infrequent in tuberculosis, especially in the elderly. Care should be considered for the interpretation with the elderly, immunocompromised, chronic and severely diseased patients.

Purpose:Hospitals provide top medical service using exceptional manpower, medical technology, and state-of-the-art equipment, thus raising the standard of customer satisfaction. In addition, their medical service is becoming higher than before. One-stop service is a good way to improve the quality of customer-centered service as a qualitative marketing strategy. This study thus aims to facilitate subsequent research and compare customer satisfaction before and after one-stop service. Methods: The study included 72 patients who received the reserved examination and one-stop service for 20 days from April 23 to May 12, 2014. The surveyed questionnaire data were analyzed using SPSS 18.00. Results: The comparison results of customer satisfaction showed that the satisfaction score was generally high in the areas of kindness of examination staff, the speedy/accuracy of work processing of examination staff, and the kindness of reservation staff. The group before one-stop service showed their dissatisfaction with repeated visits and difficulty of booking a desired day. The group after one-stop service showed dissatisfaction with the long waiting time for examination or same-day treatment. Conclusion: The one-stop service showed good results, but new uncomfortable issues for the customer were revealed as well, which may result in more work of employees. Considering the characteristics of various clinical departments, the author hopes to find an efficient operation plan through the development and improvement of an appropriate one-stop service method.

Purpose: Sonongraphic examinations such as extended Focused Assessment with Sonography in Trauma (eFAST) are widely used in Emergency Departments. This study is designed to determine student achievement by teaching medical college students through short training. Methods: 38 participants in their 3rd year of medical school were enrolled in this study. An Emergency Medicine physician trained the students to 2 hours of theoretical training followed by 2 hours of hands on training. Results: The average age of students was $28.1{\pm}3.4$, with 21 male students. The average of pre-educational test results were $60.4{\pm}8.9$ and post-educational exam results were $80.1{\pm}14.5$ (p<0.001). The average success rate of eFAST was 87.5%. But success rate of each items were lowest in checking the hepatorenal recess and the splenorenal recess, each success rate, 65.8% and 68.4%, consecutively. The questionnaires filled out after the study showed that the students were highly interested in this education and that they found the education easy to understand. They also answered that eFAST education is necessary in the medical college curriculum. Conclusion: This study shows that eFAST can be effectively taught to students through short training.

Objective: Recent studies demonstrated that core needle biopsy (CNB) can effectively reduce the possibility of inconclusive results and prevent unnecessary diagnostic surgery. However, the effectiveness of CNB in patients with suspicious thyroid nodules has not been fully evaluated. This prospective study aimed to determine the potential of CNB to assess thyroid nodules with suspicious ultrasound (US) features. Materials and Methods: Patients undergoing CNB for thyroid nodules with suspicious features on US were enrolled between May and August 2016. Diagnostic performance and the incidence of non-diagnostic results, inconclusive results, conclusive results, malignancy, unnecessary surgery, and complications were analyzed. Subgroup analysis according to nodule size was performed. The risk factors associated with inconclusive results were evaluated using multivariate logistic regression analysis. Results: A total of 93 patients (102 thyroid nodules) were evaluated. All samples obtained from CNB were adequate for diagnosis. Inconclusive results were seen in 12.7% of cases. The diagnostic accuracy, sensitivity, specificity, positive predictive value, and negative predictive value for diagnosis of malignancy were 93.8%, 100%, 100%, 78.9%, and 95%, respectively. None of the patients underwent unnecessary surgery. The diagnostic performance was not significantly different according to nodule size. On multivariate logistic regression analysis, larger nodule size and shorter needle length were independent risk factors associated with inconclusive results. Conclusion: Samples obtained by CNB were sufficient for diagnosis in all cases and resulted in high diagnostic values and conclusive results in the evaluation of suspicious thyroid nodules. These findings indicated that CNB is a promising diagnostic tool for suspicious thyroid nodules.

Background: Primary aim of this study is to assess whether or not there is an increase at rate of HPV positive oropharyngeal cancers during 1996-2011 in Turkey, for comparison with prior reports from Western countries. Materials and Methods: A total of 138 newly diagnosed patients with oropharyngeal cancer were identified, 39 of which had no primary tumor specimen available and 18 patients with invalid HPV status, therefore HPV status for remaining 81 patients was evaluated. The presence and type of HPV DNA were determined with formalin-fixed paraffin embedded specimens, using an HPV DNA-based multiplex PCR assay. Associations between HPV status and clinicopathological characteristics were evaluated using a two-sample t-test for the continuous variables and the categorical variables were compared by chi-square test. Overall survival (OS) periods were calculated with Kaplan-Meier method. Results: The proportion of HPV-positive cancer has continued to increase during 2004-2011 as compared with 1996-2003. Notably, 33% (6/18) of the cases were HPV-positive in 1996-1999, 43% (9/21) in 2000-2003, 55% (11/20) in 2004-2007 and 70% (16/23) in 2008-2011. Thus, when we compared the results obtained during the 2004-2011with results of 1996-2003 period, we found that increase at HPV-positivity ratio was statistically significant (38% vs 64% p=0.012). Conclusions: This study demonstrated that HPV positive oropharyngeal cancers are increasing in Turkish patients as in the Western world.
