BACKGROUND: The EuroQol-5 Dimension (EQ-5D) is the most frequently used questionnaire in cost-utility studies such as the quality-adjusted life year measure. Nevertheless, little attention has been paid to the relationship between an individual's visual analogue scale (VAS) score and EQ-5D dimensions. The objective of this study was to assess the relationship between the EQ-5D and VAS quality of life measures after adjusting for socio-demographic factors in the Korean general population. METHODS: The Fourth Korea National Health and Nutrition Examination Survey, which is a national representative sample, was used to analyze the impact of the EQ-5D dimensions on the VAS. The known-group construct validity of the VAS was assessed by factors that included age, income and comorbidities. The ordinary linear regression models were applied to test for the effect of the EQ-5D dimensions after adjusting for socio-demographic and clinical factors. RESULTS: We found that the VAS showed good construct validity. The VAS significantly declined as age increased, and as education and income levels decreased. VAS scores decreased for all EQ-5D dimensions as the response level rose. The explanatory power of the VAS increased from 23.0% in the first model, which included only the EQ-5D dimensions and levels, to 25.0% in the full model, which included socio-demographic and clinical factors. CONCLUSIONS: While the EQ-5D dimensions were significant factors in determining the VAS, they did not, however, explain a sufficient amount of variance in the VAS. Further research is required on adding more dimensions to the EQ-5D preference-based instrument.

An automated percutaneous lumbar discectomy(APLD) have been apphed for contained lumbar disc herniation. But suggested that more exclusion criteria than disc containment was needed to improve success rate. The purposes of this study are to evaluate cIinical outcome of more than 4 years follow up of APLD, to analysis the cause of failure for longer follow up period, and to define prognostic factor of APLD. The l04 patients with contained lumbar disc herniation were treated with APLD from March 1990 to November 1992 in National Medical Center. The surgical candidates were contained focal disc herniation in MRI, sciatica than back pain, failure to conservative management at least 6 weeks and clinical and radiological correlation. And patient were excluded from this data if they had history of previous lumbar surgery and compensation claims. Among them 74 cases were followed up for over 4 years (Mean: 5.3 years). The results were accessed by questionnaire using telephone or OPD follow up. The overall success rate was 84% on 3 months follow up, but 68.9% on more than 4 years follow up by four subjective criterias (Onik, 1987). Causes of decreasing success rate were reoperation, recurrence without specific cause or after sprain and heavy work. 76% of failed cases occurred within 1 year and 40% of them underwent open discectomy. The patient sex, treated level, duration of symptom were not influenced on success rate, but age was factor related to success rate. In this study we can assess the effectiveness of APLD within 3 months in most cases and then change treatment option according to patients status, and it seems that we need more exclusion criteria than disc containment in MRI and refined patient selection in order to decrease the failures.

Ankle arthrodesis has been regarded as a good operative treatment for post traumatic and rheumatoid arthritis of ankle, and ankle arthroplasty has been also developed with several types, from 1970, by Lord & Marotte. Ankle arthroplasty is more functional & less cosmetic troublesome than arthrodesis, and with more developed prosthesis design, more good result will come. The authors operated 6 cases of total ankle arthroplasty for posttraumatic and rheumatoid arthritis of ankle, which were also indications of arthrodesis, and introduce the results and operative problems of ankle arthroplasty.

PURPOSE: To evaluate the psychometric properties of the Korean short form-36 health survey version 2 for assessing the general population and to provide normative data on the general population. METHODS: Six hundred members of the general Korean population were recruited using a multistage quota sampling method. Data quality was evaluated in terms of the completeness of the data and the response consistency index. Each psychometric property was evaluated using descriptive statistics, item internal consistency, item discriminant validity, known-group validity, internal consistency reliability, and exploratory factor analysis. RESULTS: The rate of missing data was low, and the rate of consistent responses was similar to conventional criteria. Item internal consistency was acceptable across all scales, whilst item discriminant validity was satisfactory for five of the eight scales. Social functioning was the least acceptable in terms of not only item discriminant validity but also item consistency reliability (Cronbach's alpha = .64). Test-retest Pearson correlation coefficients ranged from .54 to .80. In known group comparison, male sex, age <60 years, high educational status, and the absence of any comorbidities were associated with higher scores than their counterparts. Item factor analysis yields the presence of six factors, accounting for 68.8% of the variance. CONCLUSION: The findings of this study generally support the use of the Korean short form-36 version 2 for evaluating the general population, although caution is recommended when interpreting the vitality, social functioning, and mental health scales. Further research is needed in Korea.

Uterine sarcomas are relatively rare tumors of mesodermal origin that constitute 2-6% of uterine malignancies. Uterine sarcomas include endometrial stromal sarcoma (ESS), leiomyosarcoma (LMS), malignant mixed m llerian tumor (MMMT) of both homologous and heterologous type, pure heterologous sarcomas, blood vessel sarcomas, and lymphoma. Endometrial stromal tumors are divided into three types: 1) endometrial stromal nodule, 2) low-grade stromal sarcoma or endolymphatic stromal myosis, and 3) endometrial stromal sarcoma. The low grade endometrial stromal sarcoma is very rare. It shows occasional local recurrence, which might arise from endometrial stroma, from adenomyosis, and rarely from endometriosis. We have experienced a case of low grade endometrial stromal sarcoma of the uterus in a 54-year-old woman, which is presented with a review of literatures.

PURPOSE: This study was to measure and identify the differences of perceived confidence in practice of core basic nursing skills performed by new graduate nurses in Korea. METHODS: The tool used in this study was a questionnaire for measuring the confidence in 20 items of core basic nursing skills which was structured based on Korean Accreditation Board of Nursing Education tool. 231 new graduate nurses participated in this study. The reliability of this questionnaire had Cronbach's alpha .918. RESULTS: Subjects who experienced simulation education and standard patient education were 86.6% and 35.9%, respectively. Item enema intervention, tracheostomy care, and blood transfusion showed low practice confidence level. These items showed significant differences on whether the subjects experienced simulation and clinical practicum or not. CONCLUSION: Developing and managing clinical education program under deep cooperation between practicum agency and clinical instructor are needed. Simulation practicum will complement insufficient core basic nursing skills between newly graduated nurses before they allocate at the clinical department.

Journal of Preventive Medicine and Public Health 2022;55(3):243-252
Objectives:
Very limited previous research has investigated the utility weights of prostate-related diseases in the general population in Korea. The purpose of this study was to calculate the utility of prostate-related health states in the Korean general public using the standard gamble (SG) method.
Methods:
Seven health states for hypothetical prostate cancers, 1 for benign prostate hyperplasia, and 1 for erectile dysfunction were developed based on patient education material and previous publications. In total, 460 responses from the Korean general population were used to analyze the utility of prostate-related health states. Computer-assisted personal interviews were conducted, and utility values were measured using a visual analogue scale (VAS) and SG. Mean utility values were calculated for each prostate-related health state.
Results:
The mean utility values of prostate cancer derived from SG ranged from 0.281 (metastatic castration-refractory prostate cancer) to 0.779 (localized prostate cancer requiring prostatectomy). The utility value of benign prostate hyperplasia was 0.871, and that of erectile dysfunction was 0.812. The utility values obtained using the SG method in all conditions were higher than the values obtained by VAS. There were no significant demographic variables affecting utility values in multivariate analysis.
Conclusions
Our findings might be useful for economic evaluation and utility calculation of screening and interventions for prostate-related conditions in the general population.

The effect of hyperoxia and smoking on retinal and optic nerve head microcirculation, and O2 reactivity in smokers and non-smokers were investigated using HRF(Heidelberg Retinal Flowmeter). 10 eyes of 10 young healthy non-smoking volunteers and 10 eyes of 10 young healthy smoking volunteers were investigated. Blood flow measurements were performed using HRF before and after 100% oxygen was applied to the subjects. In the non-smoking group, retinal flow was reduced by 33%, retinal volume by 24%, optic nerve head flow by 16% and optic nerve head volume by 18%. In the smoking group, retinal flow was reduced by 19%, retinal volume by 16%, optic nerve head flow by 16% and optic nerve head volume by 16%. The difference of O 2 reactivity between smokers and non-smokers was statistically significant in the retinal blood flow and volume, but not significant in the optic nerve head flow and volume. These results indicate that hyperoxia leads to a decrease in capillary blood flow of the retina and optic nerve head secondary to vasoconstriction, and that smoking decreases O2 reactivity in retinal microcirculation. The findings might be based on the long term effects of nicotine on the vascular system in smokers.
