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.

BACKGROUND: The revised Consolidated Standards for Reporting of Trials (CONSORT) were developed to improve the reporting of Randomized Controlled Trials. We studied to survey the extent to which RCTs report items included in the revised CONSORT recommendations. METHODS: A descriptive survey of RCTs enrolled in 2005 at KoreaMed, which is a representative database in Korea was done. The main outcome measures were the proportion of RCTs that reported each of 22 checklist items of CONSORT. RESULTS: We identified 125 RCTs from 26 journals. Random sequence implementation (0%), estimated effect size and its precision (0%), sample size determination (8.9%), method of random sequence generation (7.3%), allocation concealment (3.2%), participant flow (4.8%) and any other analysis (7.3%), generalizability of the trial findings (0.8%) were pooly reported. CONCLUSION: The proportions of following the CONSORT recommendations in Korean medical journals were very low. An effort to improve the reporting of RCTs by application and recommendation of CONSORT statement is required.

BACKGROUND: Over the past decade, considerable evidence has been accumulated showing that social networks influence health. However few valid and reliable instruments exist for assessing social networks among elderly population. Therefore, we translated the Lubben social network scales (LSNS) and tested the validity and reliability of Korean version. METHODS: Ten items, self-administered questionnaires were translated by multidisciplinary committee members. Also they were reverse translated by bilingual and modified from pretest procedure. Reliability was tested by 4 weeks testretest reliability and internal consistency (Cronbach's alpha). Validity was tested by factor analysis and construct validity comparison with the Korean version of Duke-UNC and Korean Health Related Quality of Life Scale (KQOLS) were tested for validity testing. RESULTS: Cronbach's alpha was 0.75. Four weeks test-retest Pearson coefficient was 0.78 (P < 0.0001). Correlation coefficient with the Korean version of Duke-UNC was 0.58 (P < 0.0001). Correlation coefficient with social function domain of KQOLS was 0.40 (P < 0.0001). Principal components analysis identified 3 factors. Three contents areas are family and friends networks, interdependent social support and living arrangements. CONCLUSION: Korean version of LSNS is both valid and reliable instrument, but fine refinements will be needed to adapt for use in practical settings.

OBJECTIVES: The purpose of this study was to investigate the correlation of periodontitis with metabolic syndromes and menopause status. METHODS: The 2013 Korea National Health and Nutrition Examination Survey data of 645 postmenopausal and 663 premenopausal women were analyzed using the Pearson's chi-squared test and multiple regression analysis with the Statistical Package for the Social Sciences (PASW statistics) software version 21.0. Metabolic syndromes and community periodontal index (CPI) were analyzed. RESULTS: CPI 3, CPI 4 (P<0.001), and the prevalence of periodontal disease were significantly higher in the postmenopausal group (P<0.001). Periodontal disease was significantly higher (P<0.001) in postmenopausal women not using dental floss (2.69 times), hypertensive postmenopausal women (1.60 times), and premenopausal women with high blood glucose levels (1.67 times). In the multiple logistic regression analysis, after adjusting for age, smoking habit, and alcohol consumption, significant risk factors for periodontal disease were the lack of dental floss use (odds ratio [OR]: 1.83; 95% confidence interval [CI]: 1.26–2.67), menopause (OR: 1.71; 95% CI: 1.22–2.41), and number of metabolic syndromes (when 1 or 2, OR: 2.22 and 95% CI: 1.50–3.29; when 3 or more, OR: 2.22 and 95% CI: 1.58–3.13). CONCLUSIONS: In summary, menopause status is associated with periodontal disease. Therefore, oral health programs for middle-aged women with menopause and metabolic syndromes should be conducted to improve their oral health-related quality of life.

OBJECTIVES: The purpose of this study was to investigate the reasons for unmet dental needs in Korea and to find ways to improve dental care accessibility by using data from the 6th National Health and Nutrition Survey. METHODS: This study was performed using data collected from the 6th National Health and Nutrition Examination Survey (KNHANES). A total of 2,251 subjects were selected for the study. Statistical analysis was performed using SPSS 21.0 on data files obtained according to complex sampling design, and a significance level of 0.05 was used. General characteristics of the subjects, oral health status, and unmet dental needs were examined for a complex sampling frequency analysis, and the differences in distribution were analyzed using chi-square analysis. Relevant factors were determined using logistic regression analysis. RESULTS: According to the logistic regression analysis, in Model 1, gender, household income, employment status, and subjective health status were found to be significantly related to unmet dental needs (P<0.05). In Model 2, subjective health status, subjective oral health status, and chewing difficulty were significantly related to unmet dental needs (P<0.001). Model 3 showed a significant relationship between subjective health status, subjective oral health status, chewing difficulty, periodontal disease, and unmet dental needs (P<0.001). CONCLUSIONS: We conclude that the reasons for the unmet dental needs in Korea are socioeconomic status, general health status, and oral health status. In the future, economic barriers to obtaining dental care need to be overcome through improvements in health insurance policies and systems and diversification of private insurance. Oral health should be improved through oral health education, which can create awareness and provide motivation for maintaining oral health.

OBJECTIVE: To evaluate differences in skeletal maturity in relation to vertical facial types and to compare differences in the skeletal maturity of the cervical vertebrae and hand-wrist in females. METHODS: This study included 59 females aged 7 to 9 years with skeletal Class I malocclusion. The participants were categorized into three groups (low, normal, and high) according to the mandibular plane angle. Skeletal maturity was measured using skeletal maturity indicators (SMIs) and the Tanner–Whitehouse III (TW3) method on hand-wrist radiographs and by using cervical vertebrae maturation indicators (CVMIs) on lateral cephalometric radiographs. RESULTS: The SMI was higher in the high-angle group than in the low-angle group (p = 0.014). The median TW3 bone age was 11.4 months higher in the high-angle group than in the low-angle group (p = 0.032). There was no significant difference in CVMI among the three groups. Skeletal maturity showed a weakly positive correlation with the mandibular plane angle (SMI, r = 0.391; TW3, r = 0.333; CVMI, r = 0.259). CONCLUSIONS The skeletal maturity of the hand-wrist in females with a high mandibular plane angle was higher than that in females with a low mandibular plane angle. Obtaining additional hand-wrist radiographs may facilitate evaluation of skeletal maturity of females. In females with a high mandibular angle, the time to commence orthodontic treatment may be earlier than that in females with a low mandibular angle.

OBJECTIVES: The purpose of this study was to use the components of the European Quality of Life-5 dimension (EQ-5D) scale to investigate the oral health status and health-related quality of life of adults in order to collect basic data on how to improve quality of life. METHODS: This study was conducted in 2014. Data from the 6th Korean National Health and Nutrition Examination Survey (sixth term; 2 years) were analyzed by utilizing the raw information from the disease management headquarters. The 2,805 subjects were 19 to 59-year-old adults who were not missing values of the main missing value of oral health status in variables and the EQ-5D. Statistical analysis was performed by frequency analysis and chi-squared (χ2) and t-tests. Analysis of variance was performed using multiple regression analysis. The significance level was determined to be 0.05. RESULTS: Dental pain and mobility (P<0.005), pain and discomfort (P<0.005), chewing problems and speaking discomfort, anxiety and depression (P<0.05), subjective oral health awareness, mobility (P<0.001), self-care (P<0.05), usual activities (P<0.05), pain and discomfort (P<0.005) were significantly related. In the effect on the components of the EQ-5D by logistic regression analysis, gender, age, education level, household income, chewing problems, and periodontal disease prevalence were significant variables in the quality of health-related life. CONCLUSIONS: The results showed that oral health status significantly influenced the quality of life in adults. Through the recognition of the impact of oral health on health-related quality of life, we expect that the data from this study will help promote the development of oral health and oral health education programs for the maintenance and promotion of adult health.

OBJECTIVES: The purpose of this study was to analyze the OHIP-14 (Oral Health Impact Index) and EQ-5D (health-related quality of life) scores for women in some areas, and to provide basic data as the basis for oral health and systemic health-related quality of life methods improving. METHODS: The subjects included 418 women aged 20-65 years, living in Busan and Gyeongnam between July 20 and September 30, 2014. RESULTS: OHIP-14 and EQ-5D scores increased with age and educational level; scores were lower in subjects with systemic disease and those with a non-professional occupation. Increased oral health awareness and recognition are both bad health, menopause oral health in one person was related to quality of life, and health-related quality of life scores were significantly lower (P<0001). When considering the oral care OHIP-14 score for more than a year and a time in the scaling 56.07 points, if not receiving was found as a factor affecting the OHIP-14 with 53.33 points (P<0.05), OHIP-14. Higher EQ-5D indicated a significant difference (P<0.001). The OHIP-14 score for factors affecting oral health behavior, depression score, menopause, dry mouth, monthly income, presence of systemic disease, and dentures showed a significant difference for body weight (P<0.01). Significant differences in EQ-5D scores were found for systemic diseases, subjective general health, depression score, and menopause score (P<0.01). CONCLUSIONS: OHIP-14 and EQ-5D will be helpful in the development of oral care and oral health education programs for women.
