Authors reviewed 28 cases of displaced acetabular fracture treated operatively from Februay 1991 to January 1996 and followed up more than 1 year. The clinical results were retrospectively analyzed with consideration of surgical problems and complications. The results were as follows; 1. According to Letournels classification, we had 16 elementary fractures(57%) and 12 associated fractures(43%). 2. Kocher-Langenbeck approach in 16 cases, ilioinguinal in 9 cases, extended iliofemoral 2 cases and combined approach in 1 case were used. 3. The devices for internal fixation were as follows: screw only in 12 cases(elementary fracture 9cases, associated fracture 3 cases), plate and screw in 16 cases(elementary fracture 7 cases, as-sociated fracture 9 cases). 4. There were complications such as 3 degenerative arthritis, 2 superficial wound infection, 1 iatrog-enic sciatic nerve palsy and 1 avascular necrosis of femoral head and no postoperative heterotro-phic ossification. 5. Satisfactory reduction by radiologic criteria was gained in 23 cases(82%). Satisfactory results by clinical criteria(by dAubigne & Postels) was gained in 21 cases(75%). Only 2 patient with a satisfactory radiologic reduction was clinically unsatisfactory. It seems that the satisfactory operative reduction of the fracture is the factor that correlates best with a satisfact-ory clinical result.

In an effort to reduce the false-negative rate of PAP smear, several new technologic screening methods have recently evolved. Cervicography is one of these methods. The purpose of this study was to evaluate the screening use of cervicography as an adjunctive method and the clinical effectiveness of cervicography in korean reports, compared with other countries. And we estimated the specificity and sensitivity of cervicography in cervical cancer screening in several korean reports. The results were : 1. The sensitivity of cervicography and pap smear was 89.2% and 85.7%. 2. The false negative rate of cervicography and pap smear was 3.8% and 22.4%. 3. When cervicography and Pap smear were used conjointly, the sensitivity was higher than for cervicography or pap smear used alone(95.7% vs 89.2%, 95.7% vs 85.7%) Cervicography is one of the useful screening method for detect cervical cancer, However when cervicography are used in conjunction with Pap smear, the detection rate of cervical cancer will be increased.

OBJECTIVES: The objectives of this study were to determine the relationship between lifestyle-implementation and metabolic syndrome in an electronics research and development company, and to provide a foundation for health providers of health management programs for setting priorities. METHODS: From July 1 to July 16, 2008 we carried out a descriptive cross-sectional survey. Consecutive workers of one R & D company in Seoul, Korea (N=2,079) were enrolled in study. A checklist for lifestyle (from the National Health Insurance Corporation) consisted of questions regarding diet, drinking, smoking and exercise. After the survey, researchers obtained data from health profiles for metabolic syndrome(waist-circumference, triglycerides, HDL cholesterol, blood pressure and fasting blood sugar level). Lifestyle was recorded as good or not good. Statistical analysis of metabolic syndrome and the lifestyle of subjects was done using multiple logistic regression analysis. RESULTS: The prevalence of metabolic syndrome in our study gropu was 13.3% (N=277). After adjustment for age, the adjusted odds ratios (odds ratio, 95% confidence intervals) for metabolic syndrome increased in proportion to the number of bad habits: two (1.72, 1.23-2.44), three (2.47, 1.73-3.56), and four (3.63, 2.03-6.34). Relative to subjects eating both vegetables and meat', the OR for 'meat' eaters was 1.66 (1.18-2.31). Compared with 'non-smokers and ever-smoker', the OR for 'current-smoker' was 1.62 (1.25-2.10). Compared with 'Healthy drinker', the OR for 'unhealthy drinker' was 1.38 (1.05-1.83). CONCLUSIONS: Poor lifestyle was associated with an increased likelihood of metabolic syndrome. These findings suggest that lifestyle-based occupational health interventions for young employees should include a specific diet, smoking cessation, and healthy-drinking programs.

An applied technique of contrast enhancement for X-ray image is proposed which is based on combined enhancement of scaling and wavelet coefficients in discrete wavelet transform space. Conventional contrast enhancement methods such as contrast limited adaptive histogram equalization (CLAHE), multi-scale image contrast amplification (MUSICA) and gamma correction were applied on scaling coefficients to enhance the contrast of an original. In order to enhance the detail as well as reduce the blurring caused by up scaling of contrast modified scale coefficients from lower resolution, the sigmoid manipulation function was used to manipulate wavelet coefficients. The contrast detail mammography (CDMAM) phantom was imaged and processed to measure the image line profile of results and contrast to noise ratio (CNR) comparatively. The proposed technique produced better results than direct application of various contrast enhancement methods on image itself. The proposed method can enhance contrast, and also suppress the amplification of noise components in a single process. It could be useful for various applications in medical, industrial and graphical images where contrast and detail are of importance.

Cervical cancer is the second most common gynecological cancer among Korean women. While nationwide screening program has developed, the pathogenesis of cervical cancer is unknown. The aim of this study was to compare the protein expression profiles between cervical squamous carcinomas and normal cervical tissues in order to identify proteins that are related to the cancer. Three cervical cancer tissue samples and three normal cervical tissue samples were obtained and protein expression was compared and was identified in the samples with the use of matrix assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF-MS). A total of 20 proteins that showed up-regulated expression in the cervical cancer tissue samples were selected and identified. Seven proteins were matched to allograft inflammatory factor 1 (AIF-1), actine-like protein 2 (ALP2), brain type fatty acid-binding protein (B-FABP), NCK adaptor protein 1 (NCK-1), islet cell autoantigen 1 (ICA69), cationic trypsinogen (PRSS1), and cyclin-dependent kinase 4 (CDK4), but the remaining 13 proteins were unidentifiable. After confirmation by RT-PCR, Western blotting and immunohistochemistry, we found that B-FABP, NCK-1, and CDK4 were related to the pathogenesis of cervical cancer. These proteins are suggested as candidates of new pathological tumor markers for cervical cancer.

OBJECTIVE: To evaluate the frequency and obstetric consequences of women with uterine anomalies and correlation between obstetric consequence and congenital uterine anomalies. Materials and METHODS: A retrospective study was made on 65 patients with uterine anomalies in order to evaluate the obstetric consequence at department of obstetrics and gynecology, Soonchunhyang University Hospital from January 1994 to June 1997. The diagnosis of uterine anomalies was made with hysterosalpingogram or ultrasonogram, or at the time of cesarean section. The uterine anomalies were classified according to the classification of Buttram and Gibbons and compared the pregnancy outcome for each classification. The obstetric consequences were divided into preterm delivery, premature rupture of membranes, intrauterine growth restriction, and abnormal presentation of fetus. Statistical analysis was carried out using chi-square test, the significance was defined as P< 0.05. RESULTS: 1. The incidence of uterine anomalies accounted for 1.04% (65/6,250 deliveries). 2. The most common uterine anomalies were class III (Uterine didelphys, 47.7%). 3. We noted preterm birth rate (16.9%), premature rupture of membranes rate (20%), intrauterine growth restriction rate (9.2%) in 65 patients. 4. The rate of breech presentation was 41.5% and the mean birth weight was 2,747 gram. 5. When uterine anormalies were present, the incidence of obstetric consequences was significantly increased. CONCLUSION: We concluded that congenital uterine anomalies were closely related to obstetric consequences, such as preterm, breech presentation, intrauterine growth retardation.

PURPOSE: Transilluminated powered phlebectomy (TIPP) offers a minimally invasive operation alternative to stab avulsion for varicose veins. The purpose of this study is to compare the safety and efficacy of TIPP with conventional phlebectomy (CP) for removal of varicose veins. METHOD: A retrospective review was performed on the clinical records from March 2001 to March 2002. We divided the patients into 2 groups. The first group consisted of 87 patients (107 limbs) who had undergone TIPP. The second group of 27 patients (29 limbs) had undergone CP by the stab avulsion. We compared operation time, number of skin incisions, duration of hospital stay, patient's satisfaction scores, and complications. RESULT: Mean operation time was significantly shorter in the TIPP group than in the CP group (47.3 min vs. 64.0 min). The number of skin incision was also significantly less in the TIPP group (3.4 vs. 4.9). Length of hospital stay was significantly shorter in the TIPP group (2.5 days vs. 4.0 days). However, postoperative patient's satisfaction score was similar in both groups. 81 patients (93%) in the TIPP group developed ecchymosis postoperatively, resolved spontaneously within approximately 8 weeks. CONCLUSION: TIPP can make the better cosmetic result, shorter duration of hospitalization and operation time. These results suggest that TIPP is a feasible surgical treatment modality for varicose veins of the lower extremity. However, we should minimize postoperative ecchymosis and improve the surgical technique.

Nephrogenic systemic fibrosis is a systemic illness that only affects patients with kidney failure. Exposure to gadolinium-based contrast agents has been associated with the subsequent development of nephrogenic systemic fibrosis in patients with decreased renal function. Nephrogenic systemic fibrosis is characterized by skin induration after swelling and limited joint movement through a loss in flexibility that preferentially affects the extremities. A 58-year-old man in peritoneal dialysis developed swelling and stiffness of the lower limbs following gadolinium exposure for brain magnetic resonance imaging. This patient was diagnosed with nephrogenic systemic fibrosis by CD34 immunoreactivity of subcutaneous fibroblasts in a skin biopsy. We report, for the first time in Korea, that nephrogenic systemic fibrosis developed after gadolinium exposure in a peritoneal dialysis patient.

Methods: This is a post hoc analysis of a prospective, controlled, randomized, unblinded study with 78 Korean hemodialysis patients receiving intravenous (n = 40) or subcutaneous (n = 38) erythropoietin therapy. We evaluated hemoglobin variability by calculating the frequency of hemoglobin measurements outside the target range during all visits. The high-frequency group was defined by those with hemoglobin variability over the median value (25%) while the low-frequency group was defined by those with hemoglobin variability of <25%. Results: In this analysis, 37 patients (51.1%) were men, and the mean age was 50.6 ± 12.5 years. Twenty-five patients (35.2%) had diabetes mellitus. The frequency of the value being outside the target hemoglobin range was higher in the subcutaneous group compared to the intravenous group (0.36 ± 0.19 vs. 0.27 ± 0.12/visit, p = 0.03). The low-frequency group required significantly lower erythropoietin doses compared to the high-frequency group. In the adjusted Cox analysis, the parameter high-frequency group was a significant independent risk factor for cardiovascular events (hazard ratio, 3.53; 95% confidence interval, 1.15–10.83; p = 0.03). Conclusion The risk of missing the target hemoglobin range increased with subcutaneous administration compared with intravenous erythropoietin administration in hemodialysis patients. An increased frequency of the value being outside the target hemoglobin range was also associated with an increased risk of cardiovascular events.

BACKGROUND/AIMS: The management of small-bowel perforations associated with endoscopic retrograde cholangiopancreatography (ERCP) or endoscopic sphincterotomy (EST) is still controversial. The purpose of this study was to analyze the treatment and outcome of patients with ERCP-related perforations in a single tertiary medical center. METHODS: Of 18,379 cases of ERCPs performed between January 1990 and December 2003, twenty-six patients (0.14%) with perforation were identified and medical chart were reviewed retrospectively. RESULT: EST were performed in 10,231 patients and perforation occurred in 18 patients. Four out of 18 patients with small-bowel perforation related to EST underwent surgical operation and the rest 14 patients recovered with conservative treatment alone. Of the rest 8 perforation patients unrelated to EST, perforation occurred during the insertion of endoscope in 7 patients and catheter manipulation in 1 patient. All but one perforations associated with mechanical injury by endoscope itself were managed with an emergent laparotomy, and the one patient with perforation related to catheter manipulation recovered with conservative treatment. CONCLUSIONS: A small-bowel perforation related to endoscope per se usually required a surgery, but sphincterotomy related perforations rarely did so. The prevalence and mortality rate of small-bowel perforations associated with ERCP and/or EST were 0.14% and 0%, respectively, in a single tertiary medical center.
