Premature ejaculation is the most common male sexual dysfunction and defined as persistent or recurrent occurrences of ejaculation before or shortly after penetration. But there has never been any effective oral agents for the patients with premature ejaculation. Recently, fluoxetine, a potent serotonin reuptake inhibitor, being used as antidepressant, has been suggested to be helpful for the patients with premature ejaculation. Twenty three male outpatients with premature ejaculation were randomly divided into fluoxetine (n=12) and placebo (n=11) group. In the fluoxetine group, the dose of fluoxetine was 20 mg/day for the first one week and 40 mg/day for the remaining 5 weeks. Patient and his female partner were interviewed separately before starting medication, three weeks and six weeks after medication. The mean intravaginal ejaculation latency time increased to 187.5 seconds after 3 weeks and 254.2 seconds after 6 weeks front 46.7 seconds before treatment (p<0.05). Only 1 out of 12 patients in the fluoxetine group was able to have thrusts over 30 times before treatment. After 3 weeks of Treatment, 8of 12 patients and after 6 weeks of treatment, 7 patients were able to have thrusts over 30 times. There was no significant improvement of intravaginal ejaculation latency time and number of thrusts in the placebo group. Symptomatic improvement was noticed in 75% with fluoxetine group and 18.2% with placebo group. Side reactions of fluoxetine, fatigue and yawning, were noticed in 41% of the patients, but they did not interfere with their daily activities. These findings suggest that fluoxetine can be safely used as a good pharmacotherapeutic treatment for the patients with premature ejaculation.

Background:
Rixubis (recombinant factor IX, nonacog gamma) is indicated for the control and prevention of bleeding episodes, perioperative management, and routine prophylaxis in hemophilia B patients. This real-world, postmarketing surveillance study aimed to evaluate the safety and effectiveness of Rixubis in adult and pediatric hemophilia B patients in South Korea.
Methods:
This prospective, observational, multicenter study (clinicaltrials.gov identifier: NCT029 22231) was conducted in hemophilia B patients between April 2015 and April 2019, who were observed for up to 6 months after the initiation of Rixubis treatment. Safety was evaluated based on the number and severity of adverse events (AEs) and serious AEs (SAEs). Hemostatic effectiveness was assessed by physicians and patients by using a four-point scale and rated as excellent, good, fair, or no response based on treatment type.
Results:
In all, 58 patients were enrolled from four centers by seven physicians during the study period. The safety and effectiveness analysis sets included 57 and 54 patients, respectively. Overall, 11 AEs were reported in eight patients (14.0%), of which three were SAEs and occurred in three patients (5.3%). All 11 AEs were reported as unexpected and mild in severity, with no anaphylactic reaction, and 10 AEs (90.9%) resolved. The majority of AEs (10) were unrelated to Rixubis. Of the 142 hemostatic effectiveness assessments, 123 (86.6%) were reported as good or excellent.
Conclusion
Rixubis demonstrated an acceptable safety and effectiveness profile in the treatment of bleeding, perioperative management, and prophylaxis in hemophilia B patients in a real-world setting in South Korea.

BACKGROUND: Human T-cell lymphotropic virus type I (HTLV-I) is a retrovirus that has been identified as a cause of adult T-cell leukemia/lymphoma and tropical spastic paraparesis. HTLV-I infection is highly endemic in the southwestern islands of Japan, Caribbean basin, South America, and Africa. In 1993, we showed that the seroprevalence of antibodies to HTLV-I was 0.13% among blood donors in Korea, but surprisingly, 0.80% in Cheju-Do adjacent to endemic areas of Japan. So this study was designed to reevaluate the seroprevalence of antibodies to HTLV-I among residents in Cheju-Do. METHODS: Total 2,372 residents in Cheju-Do were tested from December 1995 to March 1996. Anti-HTLV-I antibodies were detected by the microtiter particle agglutination test. RESULTS: Among total 2,372 residents, 19 were anti-HTLV-I positive. So the overall positive rate of anti-HTLV-I antibodies was 0.80%. The positive rate in females was higher than in males (0.82% vs 0.78%). The positive rate was 1.45% in the age group of 20-29 years, 1.41% in 40-49 years, 0.91% in 0-9 years, 0.70% in 30-39 years, and 0.54% in 50-59 years. The mean age of seropositive cases is 35.2 in males and 35.4 in females, with a mean of 35.3. Geographically, high positive rate was observed in Sogwipo-City (1.37%) and Namcheju-Gun (0.83%) compared to those of Pukcheju-Gun (0.64%) and Cheju-City (0.61%), which showed high seroprevalence in districts adjacent to endemic areas of Japan. Any specific risk factors or associated disorders of HTLV-I infection could not be found among the seropositive cases. CONCLUSION: The seroprevalence of antibodies to HTLV-I in Cheju-Do was noted to be very high by the microtiter particle agglutination test. So henceforth serosurvey by confirmative laboratory tests is needed, and if high seroprevalence is showed from it, screening of blood donors for HTLV-I in Cheju-Do should be considered to prevent transfusion-associated HTLV-I infection.

OBJECTIVE: To examine the relationship between hypertension prevalence and the four commonest anthropometric measurements for obesity(body mass index(BMI), wasit-hip ratio(WHR), waist circumference(WC) and body fat in Korean adults. METHODS: We studied the cross-sectional association of the anthropometric indices and blood pressure in 1,197 individuals( who were participants in the population-based cohort study). Hypertension was defined as blood pressure 160/95 mmHg or current use of antihypertensive medication. Informations on life-style factors were obtained from personal interview. RESULTS: There were close associations between BMI, WHR and WC with blood pressure in both men and women. After age adjustment, BMI and WC showed significantly positive correlation with systolic and diastolic blood pressure levels in both men and women. Odds ratio(ORs) of being hypertensive were estimated comparing the highest to the lowest quantile, adjusting for age, smoking status, alcohol intake levels, education attainment. The simultaneously adjusted ORs of being hypertensive, comparing the highest vs the lowest categories, was for BMI 2.0(95% confidence interval(CI)=0.9-3.2) in men and 3.2 (95% CI=1.7-6.1) in women, for WC 2.1(95% CI=1.0-4.4) in men and 3.1(95% CI=1.6-5.9) in women, for fat(%) 4.2(95% CI=1.9-9.5) in men and 2.1(95% CI=1.2-3.6) in women. CONCLUSION: In addition to measures of overall obesity(BMI) as well as central obesity(WHR, WC), body fat(%) was independently associated with prevalence of hypertension. Among obesity indices, body fat was the most predictor variable in hypertensive state in male and BMI was in female.

This study was carried out to evaluate the associations between lifestyles and Body Mass Index in a group of 349 male and 65 female medical students, ages 17 to 31 years. 20.0% of male students and 3.1% of female student showed the over weight in the classification of obesity by Japan Society for Study of Obesity. There was no statistically significance in the comparison of the height body weight, body mass index, obesity index and body fat(%) according to grade in both sexes. But male students showed increasing tendency of waist-hip ratio with grade. According to obesity category, there was significant difference in the comparison of body weight, body mass index , obesity index, waist-hip ratio and body fat(%), but height. Body mass index was positively related with waist-hip ratio(r=0.6150, p=0.0001) and fat(%)(r=0.5101, p=0.0001) in males and waist-hip ratio (r=0.4734, p=0.001) and fat(%)(r=0.4522, p=0.002)in females. This study provides an opportunity to further examine the relationship of sociodemographic factors and health behaviors to obesity, and suggest the basic concept to match the obesity study to general eqidemiological cohort studies for controlling of chronic adult diseases.

OBJECTIVE: To investigate the effects of bisphenol A (BPA) on cell death pattern in neuronal development of chick embryos. MATERIALS AND METHODS: We planned to compare the cytokinetic features in the normal chick embryo and those with BPA. Fifteen eggs were divided into three GROUPS: the control group, BPA 50 microgram/g egg group and BPA 200 microgram/g egg group. Embryos were incubated for 56 hours (Hamburger & Hamilton stage 16) and then we injected BPA into embryos. The embryos were sectioned by 3 micrometer thickness at the level of wing buds and stained at 72 hours after incubation (HH stage 18). We observed cell death in the spinal cord using terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) method. RESULTS: The TUNEL-positivity markedly increased in proportion to the doses of BPA. The number of TUNEL-positive cells per section was 15.2+/-2.14 in the control group, 34.6+/-3.44 in the BPA 50 microgram/g egg group, 87.6+/-4.32 in the BPA 200 g/g egg group. Furthermore the contour of spinal cord was deformed as the doses of BPA raised. CONCLUSION: BPA causes neuronal cell death and exerts cytotoxic effect on early chick embryos. It suggests that BPA might have an effect on cytogenesis during neural tube development.

OBJECTIVES: The physical activity of Korean adolescents and its distribution based on social characteristics have not yet been fully assessed. This study intends to reveal the distribution of physical activity by its subgroups and offer possible explanatory variables. METHODS: The 3rd Korea Youth Risk Behavior Web-based Survey was analyzed for this study. The appropriateness of physical activity was defined by Korea's Health Plan 2010 and physical inactivity was assessed independently. Family affluence scale, parents' education levels, subjective economic status, grade, and school location were considered explanatory variables. All statistical analysis was conducted using SAS ver. 9.1. RESULTS: The proportion of participants engaging in vigorous physical activity was high in males (41.6%), at a low grade (38.5%), within the high family affluence scale group (35.5%). The distribution of participants engaging in moderate physical activity showed similar patterns, but the overall proportion was lower (9.8%). Low family affluence and students with lower subjective economic status reported a higher prevalence of physical inactivity. In multiple logistic regression analysis for physical activity, significant factors included family affluence scale (p<0.05). For physical inactivity, family affluence scale, parents education levels, and subjective economic status were included as significant factors (p<0.05). CONCLUSIONS: The results suggest that the physical activity and inactivity of adolescents may be affected by socioeconomic variables, such as family affluence scale. This implies the need to take proper measures to address these socio-economic inequalities.

OBJECTIVES: The object of this study was to determine the relationship between body mass index (BMI) and early menarche in adolescent girls in Seoul. METHODS: A retrospective study was conducted with 144 middle school students in Seoul who provided informed consent. We measured their body composition, and used the questionnaire survey method for data collection from November to December 2008. Past elemental body composition data were collected from elementary school health records of first year of middle school. RESULTS: The early menarcheal group was taller and heavier than the late menarcheal group (p<0.05 from 8-12 years old). The body fat percentage (%), BMI were higher in the early menarcheal girls than the late-menarcheal girls (p<0.05, age at 13). In the result of multiple logistic regression, the BMI at the age of 8 and 9 was associated with early menarche after adjusting for birth weight, breast feeding and age at menarche of the mother (BMI at the age of 8: p for trend=0.01, BMI at the age of 9: p for trend=0.04). An increase in BMI from 7 to 8 year was associated with early menarche after adjusting for birth weight, breast feeding, age at menarche of the mother (p for trend=0.048). CONCLUSIONS: The BMI at the age of 8 and 9 was associated with the early menarche of girls and increase in BMI from 7 to 8 year was associated with the early menarche of girls. These results suggest that BMI and increase in BMI before menarche cause early menarche. Although this study does not represent all Korean adolescent girls, it is one of the few studies that have investigated the temporal relationship between BMI and early menarche.

We operated on a Marfan patient who had Stanford type A acute aortic dissection, aortic root aneurysm, and aortic regurgitation. The Yacoub-David aortic root remodeling procedure which preserves native aortic valve and replaces all three aortic sinuses and ascending aorta by a Dacron graft, was applied for this patient. A 24mm Hemashield graft was designed to three tongues at the aortic root end to meet the shape of the Valsalva sinuses. The patient recovered from the procedure uneventfully and there was no aortic regurgitation postoperatively.
