PURPOSE: The purpose of this study was to test and validate a model to predict contraception behavior in unmarried men and women. METHODS: Data were collected from a questionnaire survey of 180 unmarried men and 186 unmarried women 20 years of age or over who had sexual relationships in the past 6 months. Participants were from Seoul, Kyunggi, Daegu, and Busan and data collection was done from February 19 to April 16, 2013. RESULTS: Model fit indices for the hypotheoretical model fitted to the recommended levels. Out of 15 paths, 11 were statistically significant in both. Predictors of contraception behavior in unmarried men and women were intention to use contraception and self-efficacy for contraception. Exposure to sexual content was directly significant to the intention in men only. Self-efficacy for contraception was affected by perceived threat of pregnancy and gender role attitude. In women, the two predictors were also significant except for the effect of exposure to sexual contents. CONCLUSION: Results indicate that an intervention program which increases self-efficacy in unmarried men and women contributes to effective contraception behavior. In addition, proper sexual education programs using positive aspect of mass media can help develop active participation for contraception behavior.

PURPOSE: This study aimed to identify differences in contraception behavior and related factors between unmarried female and male. METHODS: A cross-sectional survey design with a convenient sampling was used. From Seoul, 107 women and 96 men were recruited. A structured questionnaire was self-administered from July 14, 2008 to September 2, 2008. RESULTS: The average ages of women and men were 26.9 and 27.8 years old, respectively. Fifty-six percent of women and 85.4% of men have experienced sexual intercourse. There were no differences between female and male in attitude toward contraception, subjective norm, and contraception behavior, while female had higher score of self-efficacy for contraception (p=.02) and intention of contraception (p=.02). There was positive correlation with subjective norm (r=.22, p<.05), self-efficacy (r=.53, p<.01) in male and attitude (r=.32, p<.05), self-efficacy (r=49, p<.01) in female. According to the result of multiple regression, the significant factor of contraception behavior was self-efficacy for both female (beta=.49, p=.00) and male (beta=.53, p=.00). CONCLUSION: To improve contraception behavior for unmarried female and male, it is necessary to develop proper sex education program to enhance self-efficacy for contraception. Adjusted education program by this result will contribute to increase sexual health for female and male.

BACKGROUND/AIMS: Endoscopic submucosal dissection (ESD) is a novel alternative treatment for differentiated early gastric cancer (EGC) without lymph node metastasis. We conducted this study to verify the therapeutic usefulness of ESD for treating differentiated EGC compared to that of surgery. METHODS: This is a retrospective cohort study of 382 patients treated with differentiated EGC from March 2006 to May 2010. The propensity score yielded 275 matched patients. They were divided into an ESD group of 175 people and a gastrectomy group of 100 people. The patient demographics, pathologic characteristics, length of hospital stay, complication rate and survival rate were compared. RESULTS: The complication rate was higher for the gastrectomy group than for the ESD group (15.0% vs. 5.1%, p=0.007). The average length of patient hospitalization was longer after gastrectomy than after ESD (8.6 days vs. 2.4 days, p<0.001). There were two cases of mortality in the surgery group within 30 days of procedure. The 5-year survival rates of the two groups did not show a statistically significant difference (92.0% vs. 93.3%, p=0.496). CONCLUSIONS: The long-term survival rates of ESD and gastrectomy were not significantly different. The complication rate was lower for ESD than for gastrectomy, and the length of hospital stay was shorter after ESD than after gastrectomy.

The purpose of this study is to compare the effects of the femoral attachment points of the graft and knee flexion angles at the time of graft fixation on stability of posterior cruciate ligament reconstruction. We analyzed the posterior stability of the knee on 23 patients(24 knees) with posterior cruciate ligament injury whose posterior cruciate ligament had been reconstructed arthroscopically and followed for minimum 1 year period at Asan Medical Center from May 1992 to June 1994. The patients were divided into the two groups according to femoral attachment points of the graft and knee flexion angles at the time of graft fixation. The distance from the junction of the intercondylar notch with trochlear groove of the femoral attachment points and knee flexion angles were 11mm and 0°-30° in group A and 7mm and 70°-90° in group B, respectively. 11 knees were included in group A and 13 knees in group B. Posterior stability was determined by difference in posterior tibial translation between the injured and the opposite knee with Telos device. In group A, 5 cases were at the range of 0-2mm, 3 cases 3-5 mm, 3 cases 6-10mm. In group B, 10 cases were at the range of 0-2mm and 3 cases 3-5mm, respectively. Differences in posterior tibial translation on average were 3.6mm and 1.7mm in group A and B, respectively. Conclusively, arthroscopic postrior cruciate ligament reconstruction with femoral attachment point at 7mm from the junction of interconlylar notch with trochlear groove and 70°

BACKGROUND: Mitral stenosis is charcterized by decrease in mitral valve area anatomically and increase in transmitral pressure gradient hemodynamically. And these changes have been used to quantify the severity of mitral stenosis clinically. To evaluate the clinical usefulness of mitral valve resistance as a hemodynamic parameter in patients with mitral stenosis, we compared the mitral valve resistance to the clinical status of the patient with mitral stenosis, the other hemodynamic parameters and static parameter. METHODS: We analyzed and reviewed the data obtained from the consecutive 27 patients with mitral stenosis(7 male, 20 female : mean age 38+/-9 years) who had been underwent percutaneous mitral valvuloplasty(PMV). RESULTS: Befor PMV, the mitral valve resistance was significantly correlated with exercise capacity on treadmill test(r=-0.37, p<0.05), mitral valve area(r=-0.72, p<0.01), transmitral mean pressure gradient(r=0.83, p<0.01),not with cardiac output, mixed venous oxygen saturation. After PMV, the mitral valve resistance was significantly correlated with mitral valve area (r=-0.72, p<0.01), transmitral mean pressure gradient(r=0.90, p<0.01).According to the results summerizing and comparing the values of before and after percutaneous mitral valvuloplasty, the mitral valve resistance had good relationship with preexisting paramerters of severity such as mitral valve area(r=-0.82, p<0.01), transmitral mean pressure gradient (r=0.92, p<0.01). CONCLUSION: This results indicate that the mitral valve resistance is a useful hemodynamic parameter in patients with mitral valve stenosis and reflects the exercise capacity during the treadmill test which was the objective parameter of practical and clinical status of the patient well than the other hemodynamic parameters in case of remarkably reduced transmitral valve blood flow due to severe mitral valve stenosis, because the degree of change in the mitral valve resistance in relagion to the degree of change in transmitral valve blood flow is relatively more constant than the other hemodynamic parameters.

BACKGROUND: Ambulatory blood pressure monitoring is widely available in clinical practice. To evaluate the pattern of normal 24 hour variation of blood pressure and the problems in analysis of data which was obtained with use of automatic blood pressure recorder, 24 hour ambulatory blood pressure was measured. METHODS: Ambulatory blood pressure was recorded for 24 hours with automatic blood pressure monitor in 22 normotensive young adolescents. RESULTS: 1) Average 24-hour BP was 109mmHg in systolic(115+/-30 for male, 102+/-30 for female), 66mmHg in diastolic(69+/-18 for male, 63+/-19 for female) and pulse rate was 72 beats per minute(70+/-23 for male, 75+/-26 for female). 2) Data obtained from ambulatory blood pressure monitor should be analyzed after deletion of unacceptable data with use of conventional criteria. Blood pressure increase which is not accompanied by increase in pulse rate increase can be used as another criteria to rule out unacceptable blood pressure data. 3) Blood pressure was low from mid-night to 6 A.M. and began to rise slowly till mid-day and then maintained steadily through the remainder of the day. And 24 hour variation of blood pressure was more adequately assessed after application of Fourier analysis. CONCLUSIONS: These results suggest that certain deletion criteria was inevitable during analysis of the data which were obtained from ambulatory blood pressure recorder and Fourier analysis can be used as valuable smoothing technique to assess the 24-hour blood pressure profiles.

PURPOSE: To examine the details of lymphedema, upper limb morbidity, and its self management in women after breast cancer treatment. METHODS: Using a cross-sectional survey design, 81 women were recruited from a university hospital. Lymphedema was detected by a nurse as a 2-cm difference between arm circumferences at 6 different points on the arm. Degrees of pain, stiffness, and numbness were scored using a drawing of upper limb on a 0~10 point scale. Aggravating conditions and self-management for lymphedema were also recorded. RESULTS: The mean age of the participants was 52.5 years; the average time since breast surgery was 29.7 months. Histories of modified radical mastectomy (55%) and lymph node dissection (81%) were noted. Lymphedema was found in 59% of women, then pain and stiffness were prevalent most at upper arm while numbness was apparentat fingers, and the symptom distress scores ranged 3.9~6.7. Women experienced aggravated arm swelling after routine housework with greatly varied duration. Self-management was conservative with a wide range of times for the relief of symptoms. CONCLUSION: Lymphedema education for women with breast cancer should be incorporated into the oncologic nursing care system to prevent its occurrence and arm morbidity. Risk reduction guidelines, individually tailored self-care strategies, and self-awareness for early detection need to be refined in clinical nursing practices.

Intramuscular myxoma is a rare benign myxoid tumor that is difficult to differentiate from other benign soft tissue tumors and sarcoma, and as a result, intramuscular myxoma is commonly misdiagnosed as another type of soft tissue tumor. Accordingly, awareness of the existence of this condition is a fundamental requirement for treatment decision-making. Furthermore, although intramuscular myxoma appears grossly to be well-circumscribed, it can infiltrate adjacent soft tissue microscopically. Tumor resection is the recommended treatment, but appropriate surgical margin sizes remain controversial. To the best of our knowledge, this is the first South Korean report to be issued on the treatment of intramuscular myxoma of the foot.

Purpose: Treatment for epilepsy primarily involves antiseizure medications (ASMs), which can be characterized using the clinical data warehouse (CDW) database. In this study, we compared retention rates and time to successful treatment for various ASMs to reflect both efficacy and adverse effects in patients with newly diagnosed epilepsy. Materials and Methods: We identified newly diagnosed epilepsy patients with ASM treatment for more than 12 months using CDW of a tertiary referral hospital. Clinical characteristics were compared between groups with successful and unsuccessful treatment. Cox regression analysis was performed to evaluate independent variables of age, sex, comorbidities, and attributes of ASM regimens. Results: Of 2515 eligible participants, 46.2% were successfully treated with the first ASM regimen, and 74.7% with all ASM regimens with the median time-to-treatment success of 14 months. Participants with second-generation ASM as the first ASM were more likely to be successfully treated with the first regimen compared to those with first-generation ASM (51.6% vs. 42.3%, p<0.001) and more successfully treated [hazard ratio (HR)=1.26; 95% confidence interval (CI): 1.15–1.39]. Overall, valproic acid was the most common ASM across a wide range of ages under 65 years, while levetiracetam in patients aged over 65 years or lamotrigine in female adult patients. Clinical factors associated with less favorable treatment outcomes included renal disease (HR=0.78; 95% CI: 0.66–0.92), liver disease (HR=0.65; 95% CI: 0.52–0.81), depression (HR=0.70; 95% CI: 0.57–0.84), and mechanical ventilation (HR=0.58; 95% CI: 0.50–0.67). Conclusion Second-generation ASMs have the advantage of more successful treatment with fewer ASM regimen changes compared with first-generation drugs. Various comorbid conditions as well as age and sex should be considered when selecting ASMs.
