The authors analyzed clinical and radiographic results of the 87 cases which had done THRA with porous coated femoral stem followed up more than 2 years to study the difference of clinical and radiologic findings between the absence (group 1 ; 53 cases) and presence(group 2 ; 34 cases) of the porous coating in superolateral portion of the femoral stem. The following results were obtained : 1. Harris hip scores were improved 34.4 points from 56.5 points preoperatively to 90.9 points postoperatively in group Ι, and 32.7 points from 61 points preoperatively to 93.7 points postoperatively in group 2. The clinical results of the group 1 were Excellent in 45 cases, Good in 5 cases and Fair in 3 cases, and clinical result of the group 2 were Excellent in 33 cases and Good in 1 case. 2. The changes of femoral stem angle were below 2 degrees in 7 cases, above 2 degrees in 2 cases in group 1, and below 2 degrees in 5 cases, but not found more than 2 degrees of change of the femoral stem angle in group 2. 3. The osteolysis around femoral stem were 15 cases(28%) in Group 1, and 5 cases(15%) in Group 2. Diffuse osteolysis were 3 cases in Group 1, but was not observed in Group 2. 4. The vertical subsidence more than 2 mm was 3 cases in group 1, but was not observed in group 2. 5. The stable femoral stem were 51 cases in group 1, and 34 cases in group 2. The unstable femoral stem were 3 cases in group 1, but was not observed in group 2. Above results suggest that the porous coating in the superolateral portion of the femoral stem showed better results in radiologic and clinical findings in short term follow up.

PURPOSE: Tension-free hernioplasty has become the most popular procedure for the repair of groin hernias in the United States and United Kingdom. The purpose of this study is to describe a 7-year personal experience with Lichtenstein's tension-free groin hernia repair under local anesthesia. METHODS: We retrospectively studied the clinical outcome of 321 cases of Lichtenstein repairs, performed consecutively by an experienced surgeon between Jan. 1994 and Dec. 2000. RESULTS: Of the 321 cases, 242 (75.4%) were indirect, 34 (10.6%) were direct, 8 (2.5%) were femoral, 7 (2.2%) were pantaloon, and 30 (9.3%) were recurred hernias. The mean age was 55 years; 91% were male. The mean number of injections of analgesics required in the postoperative period was 3.2. The mean hospital stay following repair was 2.7 days. Complications occurred in 23 cases (7.1%). Most of these were minor, consisting of five cases of bruising or hematomas (1.6%), four superficial infections (1.3%), three seromas (0.9%), two hydroceles (0.6%), six patients with persisting groin pain for more than a month (1.8%), one foreign body granuloma, one urinary retention, and one testicular atrophy. There were no recurrences or operative deaths. CONCLUSION: Lichtenstein's tension-free hernioplasty is an easy and simple technique with less pain, minor complications and only rare instances of recurrence. This procedure can be performed on a same-day basis under local anesthesia. Lichtenstein repair may be the most promising technique for the repair of groin hernias.

BACKGROUND: The SF-6D, derived from the SF-36, is a preference-based instrument measuring health-related quality of life (HRQOL). Using this tool, we measured the HRQOL of persons disabled by stroke dwelling in Gyeongju city and identified factors affecting the HRQOL. METHODS: As of March 2008, 991 persons who had had a stroke and were aged 50 and over were identified on the Gyeongju city disabled registry. Interviewers specifically trained for this face-to-face survey gathered pertinent information including general and clinical characteristics from June to October 2008. In addition, the health status was measured using the Modified Rankin Scale, the Barthel ADL index, and the SF-36. The SF-6D index was derived from the SF-36. We analyzed the known-group construct validity and convergent validity. Finally, we performed multiple regression analyses to identify factors affecting the HRQOL. RESULTS: Of the 991 potential subjects, 498 persons participated in the interviews (response rate: 50.3%). The SF-6D indices for females and those aged 70 and over were lower than indices for males and those aged 60 and less. Correlation coefficients between the Modified Rankin Scale, the Barthel index, and the SF-6D index were relatively high (-0.533 and 0.555, respectively) and statistically significant (P<0.001). Multiple regression analyses showed that sex, age, smoking, alcohol use, comorbidity, the Modified Rankin Scale, and the Barthel index had an effect on the SF-6D index of persons with stroke, and the Barthel index was the most important factor. CONCLUSIONS: Our results indicate that the SF-6D can be a valid tool for evaluating health states of persons disabled by stroke, and functional limitation was the main factor affecting the HRQOL.

OBJECTIVES: This study was conducted to elicit quality weights for 42 EQ-5D health states with the time trade-off (TTO) method from the general population of South Korea. METHODS: We selected the same EQ-5D health states as those in the UK MVH study. The Korean version of EQ-5D questionnaire and TTO method were used for the valuation process. We interviewed 500 people as a representative sample of the general population in Seoul and Gyeonggido. The result was compared with those from UK, Japan, and USA by Spearman's rank correlation and t-test. RESULTS: TTO values for 42 EQ-5D health states and 'unconscious' state were obtained from the general South Korean population. The best one was '11112' state and the worst one was 'unconscious' state. The states worse than death were '33323', '33333', and 'unconscious' states, which had negative TTO values. There was a strong correlation between TTO values of the EQ-5D health states and those of their corresponding states from UK, Japan, and USA (Spearman's correlation coefficient: 0.885, 0.882, and 0.944, respectively, p <0.001). However, absolute TTO values of most EQ-5D health states were significantly different from those of their corresponding states in other foreign studies (UK: 41/42, USA: 32/42, Japan: 15/17). CONCLUSIONS: We found that the Korean general population TTO values for EQ-5D health states were different from those of other foreign studies, suggesting that a specific Korean valuation set should be developed and used for economic evaluation studies in South Korea.

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.

The aim of this retrospective study was to compare the amount of marginal bone loss between upper anterior area and upper posterior area with 71 upper single-tooth restorations on 2 stage machined Branemark implants since Jan 1995. The second aim was to compare the bone defect group which had dehiscence and fenetration and the others in the upper anterior region. The results were as follows. 1. The most frequent reason of missing tooth in the upper anterior region was trauma by 61%. While upper posterior region showed various reasons such as congenital missing, advanced periodontitis, trauma. 2. Peri-implantitis with fistula occurred 1 of 41 implants in the upper anterior group in 1 year after loading and 2 of 32 implants in the upper posterior group failed before loading. The 1 year success rate of upper anterior group was 97.56 %, and 93.75 % for upper posterior group. 3. The mean marginal bone loss in the upper anterior group was 0.44 +/- 0.25 mm, while 0.57+/- 0.32 mm in the upper posterior group. There was stastically significant difference in the amount of mean marginal bone loss (P<0.05). 4. The mean marginal bone loss of bone defect group was 0.40+/- 0.10 mm at one year, and 0.48+/- 0.26 mm for the control group. No statistically significant difference of mean marginal bone loss was showen between bone defect group and the others at implantation. According to the results, the upper anterior region showed less marginal bone loss than the upper posterior region. In case of missing single upper tooth, careful consideration on recipient residual ridge to determine proper implant diameter and length, sufficient healing time, proper loading would lead to implant success. Single tooth implants in the maxilla seemed to be an alternative to fixed partial dentures without damage to adjacent teeth.

OBJECTIVES: This study aimed to explore dimensions in addition to the 5 dimensions of the 5-level EQ-5D version (EQ-5D-5L) that could satisfactorily explain variation in health-related quality of life (HRQoL) in the general population of South Korea. METHODS: Domains related to HRQoL were searched through a review of existing HRQoL instruments. Among the 28 potential dimensions, the 5 dimensions of the EQ-5D-5L and 7 additional dimensions (vision, hearing, communication, cognitive function, social relationships, vitality, and sleep) were included. A representative sample of 600 subjects was selected for the survey, which was administered through face-to-face interviews. Subjects were asked to report problems in 12 health dimensions at 5 levels, as well as their self-rated health status using the EuroQol visual analogue scale (EQ-VAS) and a 5-point Likert scale. Among subjects who reported no problems for any of the parameters in the EQ-5D-5L, we analyzed the frequencies of problems in the additional dimensions. A linear regression model with the EQ-VAS as the dependent variable was performed to identify additional significant dimensions. RESULTS: Among respondents who reported full health on the EQ-5D-5L (n=365), 32% reported a problem for at least 1 additional dimension, and 14% reported worse than moderate self-rated health. Regression analysis revealed a R2 of 0.228 for the original EQ-5D-5L dimensions, 0.200 for the new dimensions, and 0.263 for the 12 dimensions together. Among the added dimensions, vitality and sleep were significantly associated with EQ-VAS scores. CONCLUSIONS: This study identified significant dimensions for assessing self-rated health among members of the general public, in addition to the 5 dimensions of the EQ-5D-5L. These dimensions could be considered for inclusion in a new preference-based instrument or for developing a country-specific HRQoL instrument.

The occurrence of carcinoma in a congenital uterine anomaly is uncommon. Indeed, malignancy of the uterine fundus with congenital uterine anomaly is quite rare, with fewer than 50 cases reported in the world liturature. Many patients go through life without the knowledge of their presence, and they are discovered at autopsy. Early diagnosis and proper management is necessary to decrease the high mortality. We present a case of endometrial carcinoma in a single horn of a bicornuate uterus.
