The objective of this study was to ascertain whether or not the high-risk human papillomavirus (HPV) test, when coupled with Papanicolaou (Pap) smears, would prove useful in the screening and management of patients in whom abnormal Pap smear results had been obtained. Concomitant high-risk HPV detection using the hybrid capture II test and colposcopy with a Pap smear were performed with 176 patients, all of whom had been screened for both cervical carcinoma and precancerous lesions. We concomitantly performed colposcopies on these patients. Upon the follow-ups, the histologic diagnoses of these patients were confirmed via either biopsy or hysterectomy. The rate of high-risk HPV detection was correlated with cytologic diagnoses and colposcopic findings. The group composed of the high-risk HPV-positive ASCUS patients exhibited a 55.7% rate of cervical intraepithelial neoplasia (CIN), a significantly higher rate than the 7.5% result obtained in the high-risk HPV-negative ASCUS group. HPV test showed high sensitivity (87%) and low specificity (62.6%) in detection of CIN and colposcopy also showed high sensitivity (88%) and low specificity (22%). Any combination of these tests improve sensitivity, but not specificity. High-risk HPV tests, when coupled with Pap smears, constituted a useful triage approach with regard to colposcopy-directed biopsies in patients in whom a cytologic diagnosis of ASCUS had been rendered.

Purpose: In South Korea, suicide mortality has rapidly increased, so it has become a major public health concern. Multicultural adolescents are regarded as a high-risk group due to their situation. In this study, we compared the prevalence and risk factors of suicide ideation between Korean and multicultural adolescents. Methods: Data from the eleventh Korean Youth Risk Behavior Web-based Survey (2015), collected by the Korean Centers for Disease Control and Prevention, were statistically analyzed using the descriptive statistics and multivariate logistic regression. The total participants were 63,376 in numbers. They were composed of 62,649 (98.9%) Korean and 727 (1.1%) multicultural adolescents. Results: I found that the prevalence of suicide ideation was significantly higher among the multicultural adolescents (15.8%) compared with those of Korean (11.3%). The risk factors of suicide ideation in the Korean group were co-residence without family, poor perceived health status, depressive mood, high stress level, poor perceived happiness level, and experience of violence. Conversely, the risk factors of the multicultural group were smoking, depressive mood, and experience of violence. Conclusion: These findings suggest that appropriate and practical prevention strategies should focus on psychological and environmental factors in order to prevent suicide ideation and reduce suicide behavior in Korean and multicultural adolescents.

Background: The objective of this study was to evaluate baseline use and positive rates of staging images (bone scan, CT) in newly diagnosed patients with prostate cancer (PCa) and to improve staging image overuse. Materials and Methods: This retrospective study covered a consecutive series of patients with PCa who underwent stage imaging at our institution between 2006 and 2011. Various clinical and pathological variables (age, PSA, biopsy Gleason score, clinical T stage, positive biopsy core rate) were evaluated by multivariate logistic regression analysis for their ability to predict a positive staging image. All patients were stratified according to the NCCN risk stratification and positive rates were compared in each risk group. Results: 410 patients (100%) underwent a bone scan and 315 patients (76.8%) underwent a CT scan. Some 51 patients (12.4%) had a positive bone scan, clinical T3 and T4 being significant independent predictors. Positive bone scan rates for low-, intermediate-, high-, and very high-risk groups were 0%, 0%, 8.25%, and 56.6%. Some 59 (18.7%) patients had a positive CT scan, with elevated PSA and clinical T3, T4 as significant independent predictors. Low-, intermediate-, high- and very high-risk group rates were 0%, 0%, 13.8% and 80.0%. Conclusions: The incidences of positive staging image in low- and intermediate- risk group were reasonably low. Following feedback on these results, staging in low- and intermediate- risk groups could be omitted.

Purpose: This study was to examine the effects of a depression intervention and suicide prevention program in adolescents with high risk of suicide. Methods: This research was designed as a nonequivalent control group pretest-posttest study. The participants were adolescents with high risk of suicide in mental health screening examination. A total of 40 adolescents (experimental group=21, control group=19) were sampled from C-gun, Chungbuk Province. The experimental group participated in the depression intervention and suicide prevention program for eight sessions while the control group did not participate in the program. Data were collected with a self-reporting structured questionnaire from November to December, 2008. SPSS/Win 12.0 was used for data analyses including chi-square test, t-test, and paired t-test. Results: After this program, there was no statistically significant difference in depression (t=1.498, p=.142) between the two groups, but depression decreased in the experimental group. There was a statistically significant difference in suicide ideation (t=2.058, p=.047). Conclusion: To decrease depression and suicide ideation in adolescents with high risk of suicide, it is necessary to offer this program in a more intensive course and for a longer period. Also, family consultation programs and individual case treatment and consultation programs should be offered.

Purpose: This study was done to identify the time interval to pressure ulcer and to determine the optimal time interval for position change depending on pressure ulcer risk in patients using foam mattress in intensive care units. Methods: The Braden scale score, occurrence of pressure ulcers and position change intervals were assessed with 56 patients admitted to an intensive care unit from April to November, 2011. The time to pressure ulcer occurrence by Braden scale risk group was analyzed with Kaplan-Meier survival analysis and log rank test. Then, the optimal time interval for position change was calculated with ROC curve. Results: The median time to pressure ulcer occurrence was 5 hours at mild or moderate risk, 3.5 hours at high risk and 3 hours at very high risk on the Braden scale. The optimal time interval for position change was 3 hours at mild and moderate risk, 2 hours at high and very high risk of Braden scale. Conclusion: When foam mattresses are used a slight extension of the time interval for position change can be considered for the patients with mild or moderate pressure ulcer risk but not for patients with high or very high pressure ulcer risk by Braden scale.

To investigate the risk perception of environmental issues, two consequtive surveys were conducted to environmental professionals using a standardized questionnaire from September to October in 1999. The number of subjects were 72 for the first survey and 68 for the second one. The questionnaire was consisted of items such as the degree of environmental pollution in Korea, risk perception of some issues on human health and ecosystem, and seriousness of the problems in the real situation in Korea. For the degree of environmental pollution in Korea, the average risk rating in the second test (7.4 point) was significantly higher than that in the first test (7.2 point). The risk perception on the general human health and ecosystem, and the seriousness in Korea situation were analyzed in the order of ′air pollution′, ′water pollution′,′soil contamination′,′waste′,′toxic chemical pollutants′,′food contamination′,′ocean contamination′, ′odor pollution′, and ′noise pollution′. Also ′toxic chemical pollutants′ problem was perceived to be the highest risk on general human health or ecosystem, and on present situation in Korea. ′Automotive vehicle exhaust′ problem was perceived to be the most severe environmental problems among specific 30 items. ′Industrial source air pollution′,′toxic air pollutants′, and ′domestic and industrial source pollutants to surface water′ were relatively severe environmental problems comparing to other problems. The pollution issues were classified into four categories by two aspects of perception; risk in general setting and seriousness in Korea situation. If the issues were highly serious in Korea and low risk perception in general setting then it is named "the Korea-specific group". Those that were all high score in two aspects, named "the Common group". Those that were all low in two aspects, named "the Nonsignificant group". And the issues were high risk perception in general setting and low seriousness in Korean situation, named "the Latent group".

In consideration of limitations of the classic economic approach to risk evaluation and the psychometric analysis of risk perception, this study applies a facilitated modeling technique to a group of college students in Korea. In this group activities, researchers did not provide a pre-selected list of risk items. Instead, 35 participants had group discussions to generate 63 risk items, to rate their risk level and to evaluate their characteristics in terms of the level of knowledge and dreadfulness. This study also analyzes the influence of mass media, online news papers in particular, on risk perception by counting the number of news articles covering key word corresponding risk items generated. The results show that there are significant differences between the rank order of risk items generated by students and that of statistical or objective risk. Psychometric analyses find that the levels of knowledge and dreadfulness have meaningful correlations with risk level. A well known or a dreadful risk demonstrates a high level of risk. Correlation analyses of media coverage and the risk level also re-confirms strong positive relations. The larger number of news articles a risk issue was covered by, the higher level of risk it showed. It means that college students generated risk items on the basis of what they were exposed by media. The role of mass media in risk perception and the importance of risk communication in risk evaluation are underlined. Implications of research findings and future research are discussed as well.

Aim: To evaluate precancerous lesions such as hyperplasia and endometrial polyps in obese postmenopausal women. Materials and Methods: Women who were referred with abnormal uterine bleeding in postmenopausal period or the presence of endometrial cells on cervical cytology in our department were investigated. Anthropometric measurements such as height, weight, body mass index, waist/hip ratio and endometrial thickness were compared between a precancerous lesion (hyperplasia and endometrial polyp) group and a pathologically normal group. Results: We detected statistically significant thickening of endometrium in patients with precancerous lesions. Moreover patients with precancerous lesions had higher body mass index than the pathologically normal group. Conclusions: We found elevated precancerous lesion rates in overweight and obese women in the postmenopausal period, of interest given that the prevalence of obesity is increasing in most parts of the world. Although screening for endometrial cancer is not recommended for the general population, in high-risk populations like obese postmenopausal women, it may be very important.
