PURPOSE: To evaluate the usefulness, patterns and appearances of false positive lesions, and technical problems of CTAP(CT Arterioportography). MATERIALS AND METHODS: CTAP was done in 45 patients in whom hepatic lesions were suggested on other radiologic studies. CTAP findings were compared with the informations obtained by operations, biopsies, and follow-up imagings. Additional findings, which were not detected in other radiologic studies, false positive manifestations, and technical errors were analyzed. RESULTS: CTAP detected 51 additional hepatic lesions which are not detected in other imaging studies. Of the 51 lesions, ten were true positive hepatic tumors, 2 were inflammatory lesions and 39 were false positive .lesions. False positive lesions included perfusion defects of periportal and perifissural areas, subcapsular perfusion defects and nonlobar, nonsegmental geographic perfusion defects. In 2 cases, CTAP aided in deciding the surgical strategy. On the other hand, there were 4 cases causing interpretational confusion and 6 cases of improper imaging due to technical errors. CONCLUSION: CTAP was valuable in detection of additional hepatic cancer lesion as well as in making the treatment plan. However, since many false positive lesions and improper imaging due to technical error occur during the examination, the understanding of such problems is essential for correct interpretation of CTAP.

PURPOSE: This study aimed to identify a relationship between the communication competence and social anxiety in nursing students. METHODS: With a cross-sectional survey, a convenience sampling of 303 nursing students was taken from P-university in Y-city. The instrument for the study was a questionnaire that is consisted of the general characteristics, an Interaction Anxiousness Scale (IAS) and a Global Interpersonal Communication Competence Scale (GICC). Data was analyzed using descriptive statistics, t-test, one-way ANOVA, Kruskal-Wallis, Pearson's correlation coefficients and stepwise multiple regression with SPSS version 21.0. RESULTS: The mean score of the IAS was 41.89+/-8.74 and the GICC was 3.51+/-0.34. Communication competence significantly differed by the satisfaction of major (F=10.86, p<.001). In addition, the satisfaction of interpersonal relationships was significantly different in both communication competence (F=17.52, p<.001) and social anxiety (F=23.85, p<.001). Social anxiety had a negative correlation with communication competence (r=-.48, p<.001). Social anxiety accounted for 55.3% of the variance-social relaxation (beta=-.62), assertiveness (beta=-.18), interaction management (beta =.14) and efficiency (beta=-.13)- of communication competence's subcategories. CONCLUSION: It was found that communication competence has an influence on social anxiety. Therefore, education programs are needed to promote communication competence for a decline of social anxiety in nursing students.

PURPOSE: The purposes of this study were to examine the level of anger, anger expression, depression, psychosomatic symptom and perceived health status, and to identify the influencing factors of anger expression in shelter residents. METHODS: This study employed a descriptive correlational design. Data were collected from 407 homeless people residing at 27 shelters using structured instruments. RESULTS: The level of anger expression was different by age, educational level, existence of children, and duration of shelter residency. Anger expression was significantly correlated with depression, psychosomatic symptoms and perceived health status. The predictors of high-level anger expression was younger age, low educational level, duration of shelter residency in Model 1 (F=6.884, p<.001, Adj. R2=.065), and depression and psychosomatic symptoms in Model 2 (F=7.197, p<.001, Adj. R2=.113). CONCLUSION: This study suggested that the homeless in the shelters had various psychological vulnerabilities, and therefore more individualized programs based on their needs and psychological health status should be provided for the homeless.

PURPOSE: This study aimed to assess the risk of developing cardiovascular disease (CVD) and to evaluate the effects of intervention for CVD prevention in construction workers. METHODS: A total of 497 workers participated the health status survey and finally 90 workers were analyzed for evaluation of the intervention with the one-group pretest-posttest design. The data were collected from the questionnaires and health examinations in the healthcare service for road constructor's CVD prevention as secondary analysis. The intervention of the healthcare was composed of CVD prevention education for all workers and face to face counselling for the high risk group of CVD risk during 6 months in workplace. Data were analyzed with descriptive statistics, χ² test, Wilcoxon signed rank test, and paired t-test. RESULTS: The moderate and high risk groups of CVD were 9.7% and 0.8%. After the intervention, the physical activity (MET-min/week) significantly increased (Z=-5.46, p<.001). But, there were no significant differences in blood pressure, fasting glucose, body mass index, and CVD risk appraisals between pre and post intervention. CONCLUSION: The findings imply that it is necessary to develop the health promotion program for construction workers which fully reflects the characteristics of individuals and the organization.

Pharyngeal dysphagia can be caused by structural abnormalities or neurological disorders such as stroke, meningitis, and other conditions. Herpes zoster (HZ), caused by the varicella-zoster virus (VZV), is a rare cause of pharyngeal dysphagia. The symptoms of HZ usually involve a painful rash with vesicles along the dermatome area, but it can also affect the cranial nerves (CN), such as CN VII (Ramsay-Hunt syndrome), and less commonly, other CN. A 69-year-old man presented with a sore throat and dysphagia symptoms. A laryngoscopy revealed multiple ulcerative mucosal lesions on the right soft palate and lateral pharynx. The patient was treated with oral valacyclovir, and although the lesions disappeared, the dysphagia symptoms remained. While dysphagia associated with a VZV infection is rare, it can occur with the additional symptoms of vocal cord paralysis. This paper reports a rare case of pharyngeal dysphagia caused by a VZV infection, and the patient presented only with the initial symptoms of sore throat and dysphagia without skin lesions or signs of vocal cord paralysis.

BACKGROUND/AIMS: Despite numerous studies on the relation of genetic polymorphisms with irritable bowel syndrome (IBS), the results still remain inconclusive. The aim of this study was to assess the possible association between SLC6A4 serotonin transporter gene linked polymorphic region (5-HTTLPR), ADRA2A -1291C>G, GNB3 825C>T, CCK1R intron 779T>C and TRPV1 945G>C polymorphisms and IBS based on Rome III criteria in Korea. METHODS: Study subjects were prospectively recruited from visitors to Seoul National University Bundang Hospital between July 2009 and January 2014. Ninety-nine IBS patients and 171 healthy controls were enrolled. Polymorphisms of above-mentioned 5 genes were genotyped. Serum serotonin from 101 participants was measured by ELISA and compared according to SLC6A4 5-HTTLPR polymorphisms and IBS subtypes. RESULTS: Regarding SLC6A4 5-HTTLPR polymorphism, L/L genotype was significantly associated with the total IBS, constipation predominant IBS (IBS-C) and mixture of diarrhea and constipation IBS (IBS-M) (adjusted OR: 4.35, 95% CI: 1.04-16.67; adjusted OR: 11.11, 95% CI: 1.69-50.00 and adjusted OR: 5.56, 95% CI: 1.05-33.33, respectively). Carrying ADRA2A -1291G allele was significantly associated with total IBS and diarrhea predominant IBS (adjusted OR: 3.37, 95% CI: 1.16-9.77 and adjusted OR: 5.64, 95% CI: 1.18-27.01, respectively). IBS-C patients showed reduced level of serum serotonin compared to controls and patients with diarrhea predominant IBS (50.2 ng/mL vs. 69.0 ng/mL and 92.9 ng/mL, P = 0.017 and P = 0.001, respectively). CONCLUSIONS: Genetic polymorphisms of SLC6A4 5-HTTLPR and ADRA2A -1291C>G could be one of the pathophysiological factors of IBS in Korea. Reduced serum serotonin shown in the IBS-C group suggested a role of serotonin in IBS, but large study is needed for confirming genotypic difference in serum serotonin level.

Coronary stent embolization is a rare event but may result in clinically relevant cardiac ischemia or peripheral embolization during the procedure. We report a case of systemic embolizations of two coil stents during the primary PTCA in acute myocardial infarction, who were treated successfully with a double wire helix technique and a gooseneck snare. Although in our experience this rare complication did not produce any clinical complications, care should be taken to prevent this possibility, especially in patients with significant vessel tortuosity, calcification, total occlusion, or mild stenosis proximal to the target lesion.
