PURPOSE: This study was done to identify the mediating effect of emotional dissonance in the relationship between emotional labor and burnout among clinical nurses. METHODS: A cross-sectional survey design was used. The participants were 257 nurses working at three general hospitals located in Seoul and Gyeonggi Province. Data were collected by convenience sampling using self-report questionnaires that consisted of general characteristics, and measures of emotional labor, emotional dissonance and burnout. Data were analyzed with descriptive statistics, t-test, ANOVA, correlation, and multiple regression. RESULTS: The findings of the multiple regression were as follows. First, surface acting of emotional labor showed significant positive effects on emotional dissonance and burnout. Second, when surface acting and emotional dissonance were entered into the regression model at the same time, surface acting showed an insignificant effect on burnout, however, emotional dissonance showed a significant effect. Finally, emotional dissonance had a mediating effect only between surface acting of emotional labor and burnout, not between deep acting and burnout. CONCLUSION: Results of the study suggest that as a way to reduce burnout, nursing administrators should develop educational programs for nurses to perform deep acting of emotional labor instead of surface acting at the moment of truth.

Among the fifty-three clinical isolates of Haemophilus influenzae, nineteen isolates including eight isolates of each biotype I-VIII, six of serotype b (Hib) strains and five of nontypeable strains were characterized by SDS-PAGE about outer membrane protein (OMP), restriction enzyme analysis (REA) and rRNA gene restriction pattems. OMP patterns showed to common band patterns in each H. influenzae isolate. Based on the two major proteins, 31KDa-38KDa, isolated strains were classified into 7 subtypes. In the OMP patterns about biotype and serotype, the specific pattern of each biotype was not distinguishable, but all of the serotype b strains were shown identical unique pattern, therefore it made distinctive difference with nontypeable strains. The digested genomic DNAs with EcoRI were identical result with rRNA gene restriction. It was more subdivided into 10 ribotypes. The most common ribotype I and serotype 1 accounted for 6 strains (31.6%) and 7 strains (36.8%) of the 19 clinical isolates, respectively. Hib isolates that were both OMP subtype 1 and ribotype I accounted for 2 strains (10.5%). In the epidemiologically unrelated strains, the putative association between the subtypes could not be confirmed. According to these results, the three methods were discriminatory and appropriate techniques for epidemiological studies of H. influenzae.

The transesophageal echocardiography (TEE) has been used for the assessment of right and left ventricular function, valvular structure and function, regional wall motion abnormalities and localization of intravascular catheters, cannular and prosthesis. We inserted the pulmonary artery catheter (PAC) under the guidance of intraoperative TEE because of the difficulty of placing PAC with the pressure tracing method in two patients. The PAC was inserted from right atrium to right ventricle with the basal four chamber view and advanced to pulmonary artery through pulmonary valve with the longitudinal view of TEE. We observed typical pulmonary arterial wave form to confirm the correct position. We suggest that the TEE can be used for successful placement of a PAC to facilitate manipulation of the catheter as an alternative method in the patients whose PAC can not be positioned with the pressure tracing method.

PURPOSE: Neuroendocrine (NE) cells of the prostate are considered to be involved in the pathogenesis of benign prostate hyperplasia (BPH). By a comparative analysis of NE cell density in BPH tissue of men who were either exposed to or not exposed to 5alpha-reductase inhibitor, we investigated the relationship between NE cells and BPH, and the effect of androgen deprivation on NE cells. MATERIALS AND METHODS: Prostate tissue specimens, obtained from 30 men by transurethral resection of the prostate or radical cystoprostatectomy, were used. Of the 30 patients, 10 had a prostate smaller than 25 ml (normal control), the other 20 had a prostate larger than 40ml, 10 of who had taken 5alpha-reductase inhibitor (finasteride) for 3 months before surgery (androgen blockade group), and 10 who had not (BPH group). The distribution of NE cells in the prostate was examined using the anti-chromogranin A (CgA) antibody, and the density of the CgA-positive cells was compared by an optical dissector method. Immunoblotting was performed using the neuron specific enolase (NSE) antibody. A Mann-Whitney U test was used in a statistical analysis. RESULTS: Most of the CgA-positive NE cells were localized between the acinar epithelial cells. The mean numbers of CgA-positive NE cells per acinus in the normal controls and the BPH groups were 1.67+/-0.78 and 4.45+/-2.54, respectively, and the difference was statistically significant (p<0.05). However, the mean number of CgA-positive NE cells in the androgen blockade group, was 4.93+/-2.17, which was similar to the BPH group. In a NSE immunoblotting study, a distinct band was observed in the BPH and androgen blockade groups, but the density of the band was higher in the androgen blockade group. CONCLUSIONS: Our results suggest that NE cells may be involved in the hyperplastic process of BPH. Inhibition of dihydrotestosterone, caused by the oral administration of the 5alpha-reductase inhibitor, failed to induce any significant change in the NE cells, probably due to the incomplete androgen blockade.

Double primary cancer is defined as the case of primary malignant tumors, which must be arise in different sites and have a different histologic appearences. The number of reported cases of double primary malignant tumors has increased in recent and the occurrence of multiple primary cancers in the same individuals is one of the interesting subjects for investigation and research in relation to the carcinogenic mechanism and/or genetic factors. We have experienced a case with double primary malignant tumors of different site origins such as stomach adenocarcinoma and rectal adenocarcinoma, which were diagnosed by biopsies with gastro and colono fiberscopy. For its great rarity, we report this case with review of literatures.

PURPOSE: The purpose of this study was to estimate the effects of lifestyle factors on metabolic syndrome (MS) among Korean adults (age> or =20). METHODS: A total of 7,798 subjects (weighted subjects=37,215,961) were recruited from the 2009 Fourth Korea National Health and Nutrition Examination Survey (KNHANES IV-3). Data were analyzed by t-test, chi2-test, and logistic regression in consideration of strata, cluster and weight as national data using the SAS 9.1 program. RESULTS: The prevalence of MS by definition of AHA/NHLBI and waist circumference cutoff points for Koreans was 22.4%. The mean clinical MS score for MS patients was 3.4, but the mean score for the non-MS group was 1.2 out of 5.0. Among the lifestyle factors, smoking (OR=1.024), stress (0.546< or =OR< or =0.587) and drinking (OR=1.005) had significant influence on the MS risk and MS scores, but exercise did not. CONCLUSION: The results of this study indicate that further research is necessary on the effect of lifestyle factors on MS risk and nurses should focus on effective programs about smoking, stress and drinking for the prevention and reduction of MS risk.

Intestinal tuberculosis has been known since antiquity. After about 1950's, effective antituberculous chemotherapy and an improved standard of living resulted in a steady decline in all forms of tuberculosis. However, intestinal tuberculosis has been reported with impressive frequency in developing countries including Korea. Disease affecting the duodenum is reported to be rare and isolated duodenal tuberculosis sparing the rest of the intestine is uncommon. We experienced a case of tuberculosis of duodenal bulb associated pulmonary tuberculosis. The diagnosis was made on the basis of the histological study of the endoscopic biopsy specimen. We have confirmed the healing of the duodenal lesion by the follow-up endoscopy after 9 months treatment of antituberculous medication.
