We noticed the treatment results of each of them after having treated the seventy-nine cases of benign prostatic hyperplasia with TUMT (N=32, Term ; 92.6-93.3), TUR-P (N=31, Term; 91.4-93.3), open prostatectomy (N=16, Term; 91.4-93.3). However, there was a difficulty to get to statistical reliability, for there was a little gap between the term of survey and the period of treatment of three groups. The results are following. In the TUMT, the maximal flow rate was improved from 8.2ml/s to 13.3ml/s and Madsen score dropped from 13.6 to 5.3, in the TUR-P they were 8.4ml/s to 16.5ml /s and 14.5 to 5.3 respectively, and in the open prostatectomy 6.8ml/s to 20.0ml/s and 15.8 to 5. 3 respectively. The degree of satisfaction of the patients themselves with each prescription was 46.9% in the TUMT. 67.7% in the TUR-P and 81.2% in the open prostatectomy. But 18.8% and l6.l% of the patients thought TUMT and TUR-P respectively ineffective. The conclusion is that open prostatectomy presented the better results than TUMT or TUR-P in the degree of satisfaction of patients and uroflowmetry during the survey period. And even though TUMT have presented lesser degree of satisfaction then TUR-P up to now, if the exact indications for the use of TUMT are found and the mechanical improvements undergo, then a number of benign prostatic hyperplasia cases seem to be treated in more safety and with lesser cost and time by TUMT instead of TUR-P.

Mystic experience is highly evaluated so as to be called as core of experience in the religious world and also becomes the subject of concern among various social groups. Psychologists and psychiatrists are concerned about it, but because of its individuality and subjectivity, the scientific approach was difficult so that only the description of mystic experience has been researched so far. There is a current report saying that mystic experience is the one of the dissociative phenomenon. And there are a lot of reports saying that dissociation is related to childhood trauma experience and rises as much as psychopathological tendencies exist. Consequently, based on the reference that mystic experience is connected with dissociation, the study has been progressed to find out the level of dissociation, psychopathology and trauma experience for religious people who experienced mystic experience but excluding patients. Among them, it has been compared between group of non-mystic experience (n=35) and group of mystic experience (n=42). We used Dissociative Experience scale-Korean version (DES-K), Symptom Checklist-90-Revised (SCL-90-R), questionnaire about trauma. The result is that the group of mystic experience had a significantly higher tendency to have dissociation and trauma experience than group of non-mystic experience. However, the difference of psychopathology has not been found.

PURPOSE: The increased use of antibiotics may be the main factor responsible for the development and spread of bacterial resistance. This study demonstrated the relation between quinolone use and the rate of isolating ciprofloxacin-resistant(CIPRO-R) Escherichia coli(E.coli) in patients with urinary tract infection(UTI). MATERIALS AND METHODS: From 2001 to 2006, we determined antimicrobial use for 2,803 in terms of the defined daily dose(DDD) and the antimicrobial use density(AUD), and we surveyed the isolation rates of CIPRO-R E.coli in UTIs in both inpatients and outpatients. We also analyzed the correlation between the number of prescriptions and the resistance rates. RESULTS: Of the 637(22.7%) CIPRO-R E.coli isolates, 297(46.6%) were from inpatients and 340(53.4%) were from outpatients. There was a statistically significant correlation between the rate of isolating CIPRO-R E.coli and the amount of quinolone use for the inpatients(r=0.815, p<0.05) as well as the outpatients(r=0.804, p<0.05). A logistic regression analysis identified previous quinolone use as the independent risk factor(odd ratio: 2.604 [95% confidence interval(CI): 1.639-4.137]) for CIPRO-R E.coli in inpatients. Also, these CIPRO-R E.coli showed low sensitivity to ampicillin and trimethoprim/sufamethoxazole(TMP/SMX) in the inpatients(10.4%, 27.3%) and outpatients(5.1%, 27.1%), respectively. CONCLUSIONS: Our study shows a significant correlation between ciprofloxacin resistance and quinolone use, and previous quinolone use seems to be the risk factor for CIPRO-R E.coli bacteriuria. It is necessary to keep antimictrobial therapy under constant surveillance for the prevention of CIPRO-R E.coli.

PURPOSE: We evaluated the effect of tamsulosin and nifedipine on expulsion of ureteral stones after extracorporeal shock wave lithotripsy(ESWL). MATERIALS AND METHODS: We evaluated 96 upper or lower ureteral stone patients. All patients received a single session of ESWL with a piezolith- 3000 and received twice-a-day oral treatment of 5mg trospium chloride. The patients were randomly divided into three groups. Group 1 received once a day oral therapy of 0.2mg tamsulosin. Group 2 received once a day oral therapy of 30mg nifedipine. Group 3 was used as the control group. All patients took oral medication for 2 weeks, and then we analyzed the stone expulsion rate, side effects, and mean numbers of emergency room(ER) visits for pain control. RESULTS: There were no differences in the 3 groups in stone size, location, age, and sex. The total stone expulsion rate was significantly higher in group 1(84.4%) compared with group 3(60.6%)(p=0.032). Patients with lower ureteral stones in group 1 showed a higher expulsion rate(94.1%) than those of group 3(66.7%)(p=0.042). There was no difference in stone expulsion rates between group 2(67.7%) and group 3(60.6%). CONCLUSIONS: These result suggest that adjunctive medical therapy with tamsulosin after an ESWL increased the stone expulsion rate of ureteral stones, especially lower ureteral stones.

PURPOSE:
. The purpose of this study is to evaluate translucency and masking ability of translucent zirconia compared to conventional zirconia and lithium disilicate materials.
MATERIALS AND METHODS:
. Three types of zirconia blocks with different yttria contents (3Y, 4Y, 5.5Y) and LS blocks (Rosetta SM) were used.Ten specimens for each group were fabricated with 10 mm diameter, with both 0.8 mm and 1.5 mm thicknesses (± 0.02 mm). All groups of zirconia specimens were sintered and polished according to the manufacturer’s instructions. To calculate the translucency parameter (TP), CIELAB value was measured with a spectrophotometer on black and white backgrounds. To investigate the color masking abilities, background shades of A2, normal dentin, discolored dentin, and titanium were used. The color difference (ΔE) was calculated with the CIELAB values of A2 shade background as a reference compared with the values in the various backgrounds. One-way ANOVA and Bonferroni tests were conducted (P < .05).
RESULTS:
. The TP values of zirconia specimens increased as the yttria content increased. All materials used in the study were able to adequately mask normal dentin shade (ΔE < 5.5), but were incapable of masking severely discolored dentin (ΔE > 5.5). On the titanium background, all materials of 1.5 mm thickness were able to mask the background shade, but with a thickness of 0.8 mm, only 3Y-TZP and 4Y-PSZ were able to mask titanium background.
CONCLUSION
. All zirconia materials and lithium disilicate specimens used in this study were unable to adequately mask the shade of severely discolored dentin. It is recommended to use 3Y-TZP or 4Y-PSZ with a sufficient thickness of 0.8 mm or more to mask titanium.

Hypermobility of the bladder neck in response to increased intraabdominal pressure is the anatomical cause of female stress urinary incontinence ( SUI) and the degree of bladder neck movement has been used to classify SUI patients and to guide management decisions. We performed transvaginal ultrasonography in 14 SUI patients and 20 normal female as control to assess its role on the demonstration of the anatomical features associated with SUI. We adopted three anatomical factors in the sagittal plane which affect the bladder neck mobility , vertical (JY) and horizontal(JX) distance difference between pubic symphysis and bladder neck, and rotation angle difference(JZ) composed of by pubic symphysis and bladder neck during rest and stress states. There were significant differences in Y and Z between the two groups. Three months after corrective surgery for SUI these two factors showed significant improvement in all patients. It could be concluded that transvaginal ultrasonography is a safe and reliable method to diagnosis and evaluate the postoperative outcome for SUI.

PURPOSE: Although the sural nerve is the most commonly used donor for autologous nerve graft, its morbidity after harvesting is sparsely investigated. The sural nerve being a sensory nerve, complications such as sensory changes in its area and neuroma can be expected. This study was designed to evaluate the donor site morbidity after sural nerve harvesting. METHODS: Among the 13 cases, who underwent sural nerve harvesting between January 2004 and August 2009, 11 patients with proper follow up were included in the study. The collected data included harvested graft length, actual length of the grafted nerve, anesthetic and paresthetic area, presence of Tinel sign and symptomatic neuroma, and scar quality. RESULTS: In 7 patients, no anesthetic area could be detected. Of the patients with a follow up period of more than 2 years, all the patients showed no anesthetic area except two cases who had a very small area of sensory deficit (225 mm2) on the lateral heel area, and large deficit (4,500 mm2) on the lateral foot aspect. The patients with a short follow up period (1~2 m) demonstrated a large anesthetic skin area (6.760 mm2, 12,500 mm2). Only one patient had a Tinel sign. This patient also showed a subcutaneous neuroma, which was visible, but did not complain of discomfort during daily activities. One patient had a hypertrophic scar in the retromalleolar area, whereas the two other scars on the calf were invisible. CONCLUSION: After a period of 2 years the size of anesthetic skin in the lateral retromalleolar area is nearly zero. It is hypothesized that the size of sensory skin deficit may be large immediately after the operation. This area decreases over time so that after 2 years the patient does not feel any discomfort from nerve harvesting.

PURPOSE: Carcinomas of the biliary tract are considerably rare conditions. In spite of recent progress in diagnosis and treatment, resectability remains low, and the prognosis is still discouraging. This review summarizes our 12-year experience with biliary tract cancers, with particular focus on the survival rates after operation and the prognostic factors that affected the survival of patients. METHODS: Between 1987 and 1998, 268 patients with biliary tract cancers were operated on at our institution. The clinical and the pathologic data were collected, and a survival analysis was performed. RESULTS: The tumor was located in the gallbladder in 90 patients, in the proximal bile duct in 74 patients, in the distal bile duct in 54 patients, and in the ampulla of Vater in 50 patients. One hundred ninety-seven patients underwent a radical resection (resection rate: 73.5%). A curative resection was achieved in 140 patients (curative resection rate: 71.1%). The overall operative mortality after resection was 3.0%. The cumulative survival rates at five years after resection were 61.1% for carcinomas of the gallbladder, 25.8% for proximal bile duct cancers, 28.9% for distal bile duct cancers, and 48.7% for ampulla of Vater cancers. The one-year survival rates for the non-resection group were 18.2% and 26.6% for gallbladder cancers and proximal bile duct cancers, respectively. The mean survival periods for unresectable distal bile duct cancers and ampullary cancers were 4.7 months and 8.3 months, respectively. Positive lymph-node metastasis was a statistically significant, poor prognostic factor. CONCLUSION: Long-term survivals can be expected by a radical surgery for patients with biliary tract cancers. Increasing the resection rate by performing an extended procedure is essential for the improvement of treatment outcomes.

STUDY DESIGN: Retrospective study. PURPOSE: The objective of the study is to evaluate the relationship between the detection rate of lumbar disc herniation and socioeconomic status. OVERVIEW OF LITERATURE: Income is one important determinant of public health. Yet, there are no reports about the relationship between socioeconomic status and the detective rate of disc herniation. METHODS: In this study, 443 cases were checked for lumbar computed tomography for lumbar disc herniation, and they reviewed questionnaires about their socioeconomic status, the presence of back pain or radiating pain and the presence of a medical certificate (to check the medical or surgical treatment for the pain) during the Korean conscription. RESULTS: Without the consideration for the presence of a medical certificate, there was no difference in spinal physical grade according to socioeconomic status (p=0.290). But, with the consideration of the presence of a medical certificate, the significant statistical differences were observed according to socioeconomic status in 249 cases in the presence of a medical certificate (p=0.028). There was a lower detection rate in low economic status individuals than those in the high economic class. The common reason for not submitting a medical certificate is that it is neither necessary for the people of lower socioeconomic status nor is it financially affordable. CONCLUSIONS: The prevalence of lumbar disc herniation is not different according to socioeconomic status, but the detective rate was affected by socioeconomic status. Socioeconomic status is an important factor for detecting lumbar disc herniation.
