Abstract
Background The International Agency for Research on Cancer (IARC) Monograph conducted a systematic review of the relationship between asbestos and ovarian cancer. However, there may have been information bias due to the undue weight given to few articles. To address this limitation, the present study performed a meta-analysis integrating studies published both before and after the 2012 IARC Monograph on Asbestos, with the aim of investigating the association between asbestos exposure and ovarian cancer. Methods A comprehensive search of major journal databases was conducted to identify studies examining the relationship between asbestos exposure and ovarian cancer, including those featured in the 2012 IARC Monograph on Asbestos. A meta-analysis on asbestos exposure and cancer risk was performed. Results The meta-analysis of studies published after the 2012 IARC Monograph on Asbestos found a summary Standardized Mortality Ratio (SMR) of 2.04 (95% CI: 1.03-4.05; p = 0.0123; 5 studies), with a significant degree of heterogeneity among the studies (I2 = 72.99%). The combined analysis of 15 studies before and after the 2012 IARC Monograph showed an overall summary SMR of 1.72 (95% CI: 1.43-2.06; p = 0.0349; 15 studies), with a moderate degree of heterogeneity (I2 = 42.99%). Conclusion This meta-analysis provides evidence of a significant association between asbestos exposure and ovarian cancer mortality. While the possibility of misdiagnosis in earlier studies cannot be completely ruled out, recent findings suggest a robust correlation between asbestos exposure and ovarian cancer. This highlights the importance of sustained efforts to minimize asbestos exposure and protect public health.

Abstract
Postmenopausal osteoporosis arises from imbalanced osteoclast and osteoblast activity, and mounting evidence suggests a role for the osteoimmune system in bone homeostasis. Bisphosphonate (BP) is an antiresorptive agent, but its treatment failure rate can be as high as 40%. Here, we performed single-cell RNA sequencing on peripheral immune cells from carefully selected postmenopausal women: non-osteoporotic, osteoporosis improved after BP treatment, and BP-failed cases. We found an increase in myeloid cells in patients with osteoporosis (specifically, T cell receptor+ macrophages). Furthermore, lymphoid lineage cells varied significantly, notably elevated natural killer cells (NKs) in the BP-failed group. Moreover, we provide fruitful lists of biomarkers within the immune cells that exhibit condition-dependent differences. The existence of osteoporotic- and BP-failure-specific cellular information flows was revealed by cell-cell interaction analysis. These findings deepen our insight of the osteoporosis pathology enhancing comprehension of the role of immune heterogeneity in postmenopausal osteoporosis and BP treatment failure.

Abstract
BACKGROUND Bulky or multiple lymph node (LN) metastases are associated with poor prognosis in cervical cancer, and the size or number of LN metastases is not yet reflected in the staging system and therapeutic strategy. Although the therapeutic effects of surgical resection of bulky LNs before standard treatment have been reported in several retrospective studies, well-planned randomized clinical studies are lacking. Therefore, the aim of the Korean Gynecologic Oncology Group (KGOG) 1047/DEBULK trial is to investigate whether the debulking surgery of bulky or multiple LNs prior to concurrent chemoradiation therapy (CCRT) improves the survival rate of patients with cervical cancer IIICr diagnosed by imaging tests. METHODS The KGOG 1047/DEBULK trial is a phase III, multicenter, randomized clinical trial involving patients with bulky or multiple LN metastases in cervical cancer IIICr. This study will include patients with a short-axis diameter of a pelvic or para-aortic LN ≥2 cm or ≥3 LNs with a short-axis diameter ≥1 cm and for whom CCRT is planned. The treatment arms will be randomly allocated in a 1:1 ratio to either receive CCRT (control arm) or undergo surgical debulking of bulky or multiple LNs before CCRT (experimental arm). CCRT consists of extended-field external beam radiotherapy/pelvic radiotherapy, brachytherapy and LN boost, and weekly chemotherapy with cisplatin (40 mg/m²), 4-6 times administered intravenously. The primary endpoint will be 3-year progression-free survival rate. The secondary endpoints will be 3-year overall survival rate, treatment-related complications, and accuracy of radiological diagnosis of bulky or multiple LNs. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT05421650; Clinical Research Information Service Identifier: KCT0007137.

Abstract
Laparoscopic surgery has evolved with technological advances in many aspects and increasing demand for its benefits in cosmetics, fast recovery, reduced complication rates and pain. However, it still possesses drawbacks such as limited surgical movement due to the nature of rigid laparoscopic instruments. In order to overcome such limitations, several laparoscopic jointed instruments have been developed. In this prospective multicenter, single-arm cohort study, we investigated the short-term safety and feasibility of the new articulating laparoscopic instruments in benign gynecologic surgery. A total of 113 patients who were diagnosed with benign gynecologic adnexal diseases underwent laparoscopic surgery with articulating laparoscopic instruments. Surgical outcomes, including intra/postoperative complication rates, operation time and estimated blood loss, as well as surgeon's subjective evaluation of the usage of the instruments, were evaluated. The results demonstrated that the articulating laparoscopic instruments had comparable usability and produced similar surgical outcomes to conventional laparoscopic surgery. The objective parameters, such as the operative time and complication rates, as well as the subjective parameters, such as the surgeon's own evaluation of the surgical instruments' usability, demonstrated potential benefits of the instruments in benign gynecological diseases. Overall, the study demonstrated that the use of this novel articulating device is feasible in gynecologic laparoscopic surgery.

Abstract
Considerable evidence has accumulated in the last decade supporting the notion that chronic stress is closely related to the growth, metastasis, and angiogenesis of ovarian cancer. In this study, we analyzed the conditioned media in SKOV3 ovarian cancer cell lines treated with catecholamines to identify secreted proteins responding to chronic stress. Here, we observed that epinephrine and norepinephrine enhanced the secretion and mRNA expression of CXC-chemokines (CXCL1, 2, 3, and 8). Neutralizing antibodies to CXCL8 and CXCL8 receptor (CXCR2) inhibitors significantly reduced catecholamine-mediated invasion of SKOV3 cells. Finally, we found that the concentration of CXCL1 and CXCL8 in the plasma of ovarian cancer patients increased with stage progression. Taken together, these findings suggest that stress-related catecholamines may influence ovarian cancer progression through the secretion of CXC-chemokines.

Abstract
Gentian violet (GV) is known to have antibacterial and antifungal effects, but recent studies have demonstrated its inhibitory effects on the growth of several types of cancer cells. Here, we investigated the anticancer efficacy of GV in ovarian cancer cells. GV significantly reduced the proliferation of OVCAR8, SKOV3, and A2780 cells. Results of transferase dUTP nick and labeling (TUNEL) assay and Western blot assay indicated that the inhibitory effect of GV on ovarian cancer cells was due to the induction of apoptosis. Moreover, GV significantly increased reactive oxygen species (ROS) and upregulated the expression of p53, PUMA, BAX, and p21, critical components for apoptosis induction, in ovarian cancer cells. Our results suggest that GV is a novel antiproliferative agent and is worthy of exploration as a potential therapeutic agent for ovarian cancer.

Abstract
Among ovarian cancer patients with BRCA mutation or homologous recombination deficiency (HRD), the efficacy of Poly-ADP-ribose polymerase (PARP) inhibitors such as olaparib, niraparib, veliparib, and rucaparib has been proven in a number of clinical trials. BRCA mutation and HRD are currently indicated for PARP inhibitor maintenance treatment in ovarian cancer. HRD diagnostic tests examine various components, resulting in different HRD status definitions and, as a result, different treatment decisions. A number of HRD diagnostic tests exist, but test results provided by different companies may differ as they use different methods and different cutoffs. HRD prevalence difference was shown between PARP inhibitor maintenance trials. It is important to select an appropriate method that can present accurate HRD phenotypes to predict sensitivity to PARP inhibitors so that patients who are most likely to benefit from treatment are selected. Additionally, in the subset data of the PARP inhibitor maintenance trials, there was a difference in HRD prevalence by race as higher HRD prevalence in Japanese and Chinese ovarian cancer patients was shown. Further large-scale investigations on racial differences in HRD prevalence are needed and this may contribute to changes in determining the treatment plan and personalized treatment in ovarian cancer patients.

Abstract
(1) Background: Bisphosphonate treatment failure is one of the most difficult clinical problems for patients with osteoporosis. This study aimed to analyze the incidence of bisphosphonate treatment failure, associated radiological factors, and effect of fracture healing in postmenopausal women with osteoporotic vertebral fractures (OVFs). (2) Methods: A total of 300 postmenopausal patients with OVFs who were prescribed bisphosphonate were retrospectively analyzed and divided into two groups according to the treatment response: response (n = 116) and non-response (n = 184) groups. The radiological factors and the morphological patterns of OVFs were included in this study. (3) Results: The initial BMD values of the spine and femur in the non-response group were significantly lower than those in the response group (all Ps < 0.001). The initial BMD value of the spine (odd ratio = 1.962) and the fracture risk assessment tool (FRAX) hip (odd ratio = 1.32) showed statistical significance in logistic regression analysis, respectively (all Ps < 0.001). (4) Conclusions: The bisphosphonate non-responder group showed a greater decrease in BMD over time than the responder group. The initial BMD value of the spine and the FRAX hip could be considered radiological factors influencing bisphosphonate non-response in the postmenopausal patients with OVFs. The failure of bisphosphonate treatment for osteoporosis has a possible negative on the fracture healing process in OVFs.

Abstract
The adhesion molecule Nectin-4 is a new potential therapeutic target for different types of cancer; however, little is known about its diagnosis significance in endometrial cancer (EC). We found that Nectin-4 expression was significantly higher in EC tissues than in nonadjacent normal tissue. The area under the receiver operating characteristic curve value of 0.922 indicated good diagnostic accuracy for Nectin-4 expression in EC. Furthermore, Nectin-4 expression was associated with DNA mismatch repair (MMR) protein deficiency. Notably, the high Nectin-4 expression group of patients with MSH2/6-deficient EC had shorter progression-free survival than that of the low Nectin-4 expression group. The number of lymphovascular space invasion-positive patients in groups with MMR deficiency and high Nectin-4 expression was also increased compared with that in the low Nectin-4 expression group. Bioinformatics analysis revealed that alteration in Nectin-4 and MMR genes is associated with Nectin-4 expression in EC. To the best of our knowledge, this is the first study to show that Nectin-4 expression may be a potential biomarker for EC diagnosis and that high Nectin-4 expression in MMR-deficient patients with EC can predict short progression-free survival, thus providing clues to identify patients for adjuvant therapy.

Abstract
PURPOSE Laparoscopic total extra-peritoneal (TEP) inguinal hernia repair is usually performed under general anesthesia (GA) for muscle relaxation. However, TEP hernia repair may be reluctant in high-risk patients of GA. The aim of this study was to compare the outcomes of the TEP under GA and local anesthesia (LA). METHODS We retrospectively analyzed patients with inguinal hernia who underwent TEP under GA or LA in a single center from December 2016 to May 2018. The outcomes, such as demographics, duration of surgery, length of hospital stay, visual analog scale (VAS), and postoperative complications, were compared in each group. RESULTS Seventy-six patients with inguinal hernia underwent TEP under GA (n = 52) or LA (n = 24). Total operation time (mean ± standard deviation; GA, 111.6 ± 23.0 min; LA, 76.3 ± 18.0 min; p < 0.001) and length of hospital stay (GA, 38.3 ± 11.6 min; LA, 30.3 ± 15.6 min; p < 0.014) were shorter in LA group compared to GA group. There were no significant differences in postoperative VAS (1 h, p = 0.247; 4 h, p = 0.086; 12 h, p = 0.469; 24 h, p = 0.411), postoperative adverse effects (vomiting, p = 0.570; urinary retention, p = 0.214; headache, p = 0.494), and postoperative complications (seroma, p = 0.348; scrotal edema, p = 0.178; recurrence, p = 0.822) between LA group and GA group. CONCLUSION Compared with GA, there were no differences in postoperative pain and complications in patients who underwent TEP hernia repair under LA. Furthermore, in LA group, total operation time and length of hospital stay were shortened.

Abstract
The sociomedical environment is changing. In the traditional physician-patient relationship, the physician was authoritative and the patient was obedient. The contractual relationship featured patient consent to the physician’s decision. Today, the physician must explain fully the planned medical treatment, and any alternative, to the patient, who has the right to choose her treatment after considering the benefits and side-effects. The Korean Society of Gynecologic Oncology (KSGO) thus decided to standardize the surgical consent forms to meet the legal requirements of modern medicine, improve patient understanding of the surgical details, and protect medical staff from legal disputes. To determine the format and content, subcommittees for each cancer type collected and reviewed all relevant articles and the current consent forms of domestic medical institutions. After several meetings, 16 basic items to be included for each type of gynecologic cancer were selected. Also, to help patients understand the surgical details, figures were included. The revised forms were legally reviewed in terms of the appropriateness of the format and content. We also developed English versions to provide adequate information for foreign patients. We hope that these efforts will promote trust between patients and physicians, and contribute to effective treatment by laying a foundation of mutual respect. Physician must explain the planned treatment and any alternative to the patient. We developed the surgical consent forms to meet the legal requirements, improve patient understanding of surgical details, and protect medical staff from legal disputes. We expect these promote trust between patient and physician and contribute to effective treatment.

Abstract
Objective This nationwide cohort study aimed to evaluate the cause-specific mortality (probability of death by ovarian cancer, probability of death by other causes) under the competing risks of death in women with ovarian cancer. Methods The Korea Central Cancer Registry was searched to identify women with primary ovarian cancer diagnosed between 2006 and 2016. Epithelial ovarian cancer cases were identified using the International Classification of Diseases for Oncology 3rd edition. We estimated the cause-specific mortality according to age (<65 years, ≥65 years), stage (local, regional, and distant), and histology (serous, mucinous, endometrioid, clear cell, and others) under the competing risks framework; moreover, cumulative incidences were estimated. Results We included 21,446 cases. Cause-specific mortality continuously increased throughout 10 year follow-up. Compared with women aged <65 years, ovarian cancer-specific mortality (5-year, 28.9% vs. 61.9%; 10-year, 39.0% vs. 68.6%, p<0.001) and other cause mortality (5-year, 1.7% vs. 4.8%; 10-year, 2.8% vs. 8.2%, p<0.001) increased in women aged ≥65 years. This trend was consistent across all the stages and histological types. There was a substantial increase in competing risks from 1.1% in women aged <65 years to 8.0% in women aged ≥65 years in patients with early-stage (p<0.001) non-serous ovarian cancer (p<0.001). Conclusion Older age at diagnosis is associated with increasing ovarian cancer-specific mortality and competing risks. Given the substantial effect of competing risks on elderly patients, there is a need for assessment tools to balance the beneficial and harmful effects to provide optimal treatment. This nationwide cohort study analyzed 21,446 women with primary ovarian cancer to evaluate survival and cause-specific competing mortality. Older age was associated with increasing both ovarian cancer-specific mortality and competing risks. Increased awareness of competing mortality is required for the optimal treatment decisions in the elderly.

Abstract
OBJECTIVE The aim of this study was to compare the clinical outcomes of chemoradiotherapy with or without bevacizumab in patients with newly diagnosed International Federation of Gynecology and Obstetrics (FIGO) stage IVB cervical cancer. METHODS 41 patients with stage IVB cervical cancer who underwent chemoradiotherapy between August 2015 and December 2017 were retrospectively analyzed. This study included 11 patients who received bevacizumab before or after radiotherapy (group A) and 30 patients who received conventional chemoradiotherapy without bevacizumab (group B). We excluded the following patients: those with dual primary cancers; those whose pathologic diagnosis was neither squamous cell carcinoma nor adenocarcinoma; those who did not undergo radiotherapy; or those from whom follow-up data could not be collected. We analyzed the treatment responses, toxicities, progression-free survival, and overall survival rates. RESULTS A total of 41 patients were included in the analysis. The median follow-up was 19 months (range 3-108). The response rates at 3 months after treatment were 90.9% in group A and 83.3% in group B (p=0.54). After completing all treatments, the complete response rates were 81.8% in group A and 47% in group B (p=0.04). Grade ≥3 gastrointestinal toxicities, including bleeding, fistula, perforation, and obstruction, were more frequent in group A (54.5%) than in group B (6.7%) (p=0.003). The 12 month progression-free survival and overall survival rates were similar in both arms (12 month progression-free survival: 45.5% vs 46.7%, respectively, p=0.22; 12 month overall survival: 81.8% vs 72.9%, respectively, p=0.57). Patients with node-only metastasis had better 12 month progression-free survival in group B than in group A (59.1% vs 42.9%, respectively, p=0.04). However, the responses to both treatments did not differ in patients with organ metastasis. CONCLUSIONS Bevacizumab for stage IVB cervical cancer is associated with higher complete response rates. However, patients treated with bevacizumab experienced more bowel toxicities. Bevacizumab did not improve progression-free survival among patients with node-only metastasis.

Abstract
Natural attenuation represents all processes that govern contaminant mass removal, which mainly occurs via microbial degradation in the environment. Although this process is intrinsic its rate and efficiency depend on multiple factors. This study aimed to characterize the microbial taxonomic and functional diversity in different aquifer sediments collected in the saturated zone and in situ microcosms (BACTRAP®s) amended with hydrocarbons (13C-labeled and non-labeled benzene, toluene and naphthalene) using 16S rRNA gene and "shotgun" Illumina high throughput sequencing at a jet-fuel contaminated site. The BACTRAP®s were installed to assess hydrocarbon metabolism by native bacteria. Results indicated that Proteobacteria, Actinobacteria and Firmicutes were the most dominant phyla (~98%) in the aquifer sediment samples. Meanwhile, in the benzene- and toluene-amended BACTRAP®s the phyla Firmicutes and Proteobacteria accounted for about 90% of total community. In the naphthalene-amended BACTRAP®, members of the SR-FBR-L83 family (Order Ignavibacteriales) accounted for almost 80% of bacterial community. Functional annotation of metagenomes showed that only the sediment sample located at the source zone border and with the lowest BTEX concentration, has metabolic potential to degrade hydrocarbons aerobically. On the other hand, in situ BACTRAP®s allowed enrichment of hydrocarbon-degrading bacteria. Metagenomic data suggest that fumarate addition is the main mechanism for hydrocarbon activation of toluene. Also, indications for methylation, hydroxylation and carboxylation as activation mechanisms for benzene anaerobic conversion were found. After 120 days of exposure in the contaminated groundwater, the isotopic analysis of fatty acids extracted from BACTRAP®s demonstrated the assimilation of isotopic labeled compounds in the cells of microbes expressed by strong isotopic enrichment. We propose that the microbiota in this jet-fuel contaminated site has metabolic potential to degrade benzene and toluene by a syntrophic process, between members of the families Geobacteraceae and Peptococcaceae (genus Pelotomaculum), coupled to nitrate, iron and/or sulfate reduction.

Abstract
BACKGROUND To compare the efficacy of serotonin-norepinephrine reuptake inhibitors (SNRIs) treatment for chemotherapy-induced peripheral neuropathy (CIPN) METHODS:: Two authors independently searched MEDLINE, Embase, Cochran Library, and Web of Science to identify and review articles published from January 1998 until December 2018 according to selection criteria. Outcomes were expressed as mean difference, the pooled odds ratio, or relative risk in a meta-analysis model. RESULTS A total of 10 studies were included in this meta-analysis: 6 randomized-controlled studies and 4 observational studies. Meta-analysis showed that CIPN was improved after treatment with SNRI (standardized mean difference = 2.20; 95% confidence interval, 0.90-3.49; I = 93% in 3 randomized controlled studies). Somnolence and insomnia occurred in <15% of patients. Incidence of somnolence was lower than with pregabalin treatment, and insomnia was comparable to that in expectant management or pregabalin treatment. Incidence of nausea and vomiting was higher than in expectant management, but no significant difference was found when compared to expectant management. CONCLUSION From the several available studies suitable for indirect comparison, SNRI shows excellent efficacy and tolerability to CIPN. SNRI could provide an important treatment option for CIPN.

Abstract
Objective The purpose of this study was to assess the incidence rate of cervical intraepithelial neoplasia (CIN) and cervical cancer, and their costs according to age. Methods We collected data on annual incidence and medical costs of CIN and cervical cancer from 2010 until the end of 2014 from the Health Insurance Review and Assessment (HIRA) service. The CIN was classified into CIN3 (high-grade) requiring conization and CIN1/2 (low-grade) requiring observation. Results Incidence rates of CIN3 and cervical cancer are reducing over time, whereas CIN1/2 is increasing significantly (p for trend: <0.001). The peak ages of incidence were 25–29, 30–34, and 70–74 years old for CIN1/2, CIN3, and cervical cancer, respectively. The crude incidence of CIN1/2 increased by approximately 30% in 2014 compared to 5 years ago and demonstrated an increasing trend in all age groups. The CIN3 showed a significantly increasing trend in the age group of 30–39 years old, the cervical cancer was significantly reduced in all ages, except the 35–39 years old. The treatment for cervical cancer costs $3,342 per year, whereas the treatment for CIN3 and CIN1/2 cost $467 and $83, respectively. Conclusion The crude incidence rate of cervical cancer is currently decreasing among Korean women, but the incidence rates and medical costs of CIN and cervical cancer are increasing in women in their 30s in Korea. These findings suggest that different strategies by age will be required for prevention of cervical cancer in Korea.

Abstract
OBJECTIVE To evaluate the effectiveness and safety of the combination of pegylated liposomal doxorubicin with carboplatin (CD) compared with those of carboplatin and paclitaxel (CP) for platinum-sensitive recurrent ovarian, fallopian, or primary peritoneal cancer in a real-world setting in Korea. METHODS We enrolled relevant patients from 9 institutions. All patients received CD or CP as the second- or third-line chemotherapy in routine clinical practice during 2013-2018. The primary endpoints were progression-free survival (PFS) and toxicity. The secondary endpoint included the objective response rate (ORR). RESULTS Overall, 432 patients (224 and 208 in the CD and CP groups, respectively) were included. With a median follow-up of 18.9 months, the median PFS was not different between the groups (12.7 vs. 13.6 months; hazard ratio, 1.161; 95% confidence interval, 0.923-1.460; p=0.202). The ORR was 74.6% and 80.1% in the CD and CP group, respectively (p=0.556). Age and surgery at relapse were independent prognostic factors. More patients in the CD group significantly experienced a grade 3 to 4 hematologic toxicity and hand-foot syndrome (13.8% vs. 6.3%), whereas grade 2 or more alopecia (6.2% vs. 36.1%), peripheral neuropathy (4.4% vs. 11.4%), and allergic/hypersensitivity reaction (0.4% vs. 8.5%) developed more often in the CP group. CONCLUSIONS The safety and effectiveness of chemotherapy with CD in a real-world setting were consistent with the results from a randomized controlled study. The different toxicity profiles between the 2 chemotherapy (CD and CP) regimens should be considered in the clinical practice. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03562533.

Abstract
Current chemotherapy regimens have certain limitations in improving the survival rates of patients with advanced ovarian cancer. Hepatocyte growth factor (HGF) is important in ovarian cancer cell migration and invasion. This study assessed the effects of YYB-101, a humanized monoclonal anti-HGF antibody, on the growth and metastasis of ovarian cancer cells. YYB-101 suppressed the phosphorylation of the HGF receptor c-MET and inhibited the migration and invasion of SKOV3 and A2780 ovarian cancer cells. Moreover, the combination of YYB-101 and paclitaxel synergistically inhibited tumor growth in an in vivo ovarian cancer mouse xenograft model and significantly increased the overall survival (OS) rate compared with either paclitaxel or YYB-101 alone. Taken together, these findings suggest that YYB-101 has therapeutic potential in ovarian cancer when combined with conventional chemotherapy agents.

Abstract
OBJECTIVE To evaluate the effect of pretreatment with combined oral contraceptives (COC) on outcomes in women with polycystic ovary syndrome (PCOS) who underwent assisted reproductive technology for subfertility. METHODS Two authors independently searched MEDLINE, EMBASE, and the Cochran Library to identify and review articles published from October 1995 until December 2018 according to selection criteria. Outcomes are expressed as mean difference and odds ratio (OR) in a meta-analysis model. RESULTS A total of seven studies were included in this meta-analysis: one randomized controlled study and two prospective and four retrospective cohort studies. Meta-analysis showed that the COC pretreatment did not affect rate of clinical pregnancy (OR = 0.93, 95% confidence interval CI 0.65-1.34, I2 = 76%) or ovarian hyperstimulation syndrome (OR = 0.90, 95% CI 0.57-1.44, I2 = 0%). However, the rate of miscarriage in the COC group was significantly higher (OR = 1.33, 95% CI 1.02-1.72, I2 = 9%) and the rate of cumulative live birth was significantly lower compared with the control group (OR = 0.72, 95% CI 0.54-0.98, I2 = 55%). Subgroup analysis showed higher rates of miscarriage and lower rates of cumulative live birth in studies with a gonadotropin-releasing hormone (GnRH) antagonist protocol (OR = 1.69, 95% CI 1.17-2.44, I2 = 0% and OR = 0.38, 95% CI 0.29-0.50, respectively). CONCLUSION Pretreatment with COC in women with PCOS before assisted reproductive technology may have an adverse effect on clinical outcomes, especially with a GnRH antagonist protocol.

Abstract
Objective To compare the survival outcomes of adjuvant radiotherapy and chemotherapy in women with uterine-confined endometrial cancer with uterine papillary serous carcinoma (UPSC) or clear cell carcinoma (CCC). Methods Medical records of 80 women who underwent surgical staging for endometrial cancer were retrospectively reviewed. Stage I UPSC and CCC were pathologically confirmed after surgery. Survival outcomes were compared between the adjuvant radiotherapy and chemotherapy groups. Results Fifty-four (67.5%) and 26 (32.5%) women had UPSC and CCC, respectively. Adjuvant therapy was administered to 59/80 (73.8%) women (25 radiotherapy and 34 chemotherapy). High preoperative serum cancer antigen-125 level (25.1±20.2 vs. 11.5±6.5 IU/mL, p<0.001), open surgery (71.2% vs. 28.6%, p=0.001), myometrial invasion (MI) ≥1/2 (33.9% vs. 0, p=0.002), and lymphovascular space invasion (LVSI; 28.8% vs. 4.8%, p=0.023) were frequent in women who received adjuvant therapy compared to those who did not. However, the histologic type, MI ≥1/2, and LVSI did not differ between women who received adjuvant radiotherapy and those who received chemotherapy. The 5-year progression-free survival (78.9% vs. 80.1%, p>0.999) and overall survival (77.5% vs. 87.8%, p=0.373) rates were similar between the groups. Neither radiotherapy (hazard ratio [HR]=1.810; 95% confidence interval [CI]=0.297–11.027; p=0.520) nor chemotherapy (HR=1.638; 95% CI=0.288–9.321; p=0.578) after surgery was independently associated with disease recurrence. Conclusion Our findings showed similar survival outcomes for adjuvant radiotherapy and chemotherapy in stage I UPSC and CCC of the endometrium. Further large study with analysis stratified by MI or LVSI is required.

Abstract
Background. The purpose of this study was to identify factors associated with the national cervical cancer screening behaviors of married female immigrants living in South Korea. Methods. The present study dataset was collected by the National Health Insurance Services in 2014–2015. A final study population of 15,935 was considered eligible for inclusion in this study if they met the criteria for participation in the national cervical cancer screening program in 2014–2015. Results. Of the 15,935 subjects, 7837 (49%) participated in cervical cancer screening. Based on the results of the logistic regression analysis of the association between cervical cancer screening behaviors and related factors, the odds ratio (OR) for participation in cervical cancer screening among individuals older than 50 years was the highest (OR: 2.13; 95% confidence interval (CI): 1.82–2.51), and the OR increased as their duration of stay in South Korea decreased. The OR of Chinese women for cervical cancer screening participation was higher than that of non-Chinese women (OR: 1.83; 95% CI: 1.69–1.99). The OR value was 29.4 (95% CI: 25.9–33.3) among those who participated in the general health screening compared with those who did not participate. Conclusions. To improve awareness about cervical cancer screening and reduce disparities in access to healthcare, appropriate programs should be developed to promote cervical cancer screening participation to socially vulnerable classes. Continuous social attention is needed to address these issues and encourage participation in general health screening to improve the rate of cervical cancer screening.

Abstract
UNLABELLED To evaluate a possible correlation between bone mineral density (BMD) and age at menarche, the present study used the BMD dataset of the Korea National Health and Nutrition Examination Survey IV-V (KNHANES IV-V). Age at menarche had a small but significant association with BMD of the lumbar spine in premenopausal Korean females, aged 20-50 years. INTRODUCTION To investigate any correlation between bone mineral density (BMD) and age at menarche in Korean females using data from the fourth and fifth Korea National Health and Nutrition Examination Survey (KNHANES IV-V; 2008-2011). METHODS In total, 37,753 individuals participated in health examination surveys between 2008 and 2011. A total of 5032 premenopausal females aged 20-50 years were eligible. Age, height, weight, and age at menarche were assessed. RESULTS Results from the univariate linear regression and analysis of covariance (ANCOVA) indicated that age (per 1 year), height (per 1 cm), weight (per 1 kg), exercise (per 1 day/week), familial osteoporosis history (yes), parity (n = 0 to ≥4), and menarche age distribution were associated with BMD of the total femur, femur neck, and lumbar spine. After stratifying the bone area and adjusting for age, parity, alcohol intake, smoking, exercise, and familial osteoporosis history, no effect was seen for the total femur or femur neck. Age at menarche 16~17 and ≥18 years groups were associated with BMD of the lumbar spine only. CONCLUSIONS Age at menarche had a small but significant association with BMD of the lumbar spine in premenopausal Korean females, aged 20-50 years. Females with late menarche may achieve lower peak bone mass at some skeletal sites, which may put them at greater risk for osteoporosis in later life.

Abstract
OBJECTIVES Despite the possibility of early detection of cervical cancer, participation in screening programmes among young Koreans is low. We sought to identify associations between risk factors and participation in screening for cervical cancer among young Koreans. DESIGN Nationwide cross-sectional study. SETTING Republic of Korea. PARTICIPANTS 3734. MAIN OUTCOME MEASURES The Korea National Health and Nutrition Examination Survey (KNHANES V: 2010-2012) was used to evaluate factors associated with attendance for cervical cancer screening among women aged 15-39. After excluding those who were previously diagnosed with cervical cancer and those with incomplete responses to questionnaires, a total of 3734 subjects were eligible. Multi-dimensional covariates as potential predictors of cervical cancer screening were adjusted in multiple logistic regression analysis. RESULTS The participation rate for cervical cancer screening was 46% among women aged 40 or younger. The logistic analyses showed that age, education, total household income, smoking and job status among women aged 15-39 were associated with participation in cervical cancer screening (p<0.05). After age stratification, the associated factors differed by age groups. Moreover, a dose-response between participation in cervical cancer screening and high total household income in the 30-39 age group was seen. CONCLUSIONS Predictive factors differed among young women (aged 15-29 vs 30-39). Thus, age-specific tailored interventions and policies are needed to increase the participation rate in screening for cervical cancer.

Abstract
A retrospective review of intestinal transplantation (ITx) at Seoul St. Mary's Hospital was made by collecting clinical data over the past 10 years. Fifteen consecutive cases from 2004 were analyzed. Five children and 10 adults (6 months to 69 years of age) were included. Primary diseases in adults included 4 mesenteric vessel thromboses, 2 strangulations, and 1 each of visceral myopathy, malignant gastrointestinal stromal tumor (GIST), mesenteric lymphangiectasis, and injury. Pediatric cases involved 2 Hirschsprung disease, 2 visceral myopathy, and 1 necrotizing enterocolitis. Three of 7 stomas were closed using a serial transverse enteroplasty procedure before transplantation. The ITx were performed using 3 living-donor Itx, 12 deceased-donor ITx, 14 isolated Itx, and 1 modified multivisceral transplantation. Daclizumab, basiliximab, alemtusumab, or basiliximab with rabbit antithymocyte globulin (rATG) was used for the induction; tacrolimus monotherapy was used as the basic maintenance immunosuppressant; and m-TOR inhibitor was used for renal dysfunction patients. Seven cases of acute cellular rejection were treated with rATG. Three cases of antibody-mediated rejection were treated with rituximab alone or with rituximab and bortezomib combination. There were 4 cases of early mortality within 6 months after Itx. Causes of death were declamping shock, cardiac tamponade with acute cellular rejection, dysmotility, and sepsis. Surgical complications consisted of 1 feeding jejunostomy displacement, and a minor leakage at a colo-colostomy site. One-year survival of the patient and graft was 73.33% (Kaplan-Meier survival curve). Although the total number of ITx is small, its social impact has been remarkable in changing the related laws and reimbursement policy in Korea.

Abstract
In this study, we examined whether the peroxisome proliferator-activated receptor γ (PPARγ) agonists, ciglitazone (CGZ) and troglitazone (TGZ), induce cell death in human cervical cancer HeLa cells. The cells were treated with a range of CGZ or TGZ doses for 24 or 48 h. Low concentrations of CGZ (≤10 μM) or TGZ (≤20 μM) had no effect on cell viability whereas higher doses induced cell death in a time- and dose-dependent manner as evidenced by the detection of activated caspase-3 and PARP cleavage. Treatment with the PPARγ antagonist GW9662 followed by PPARγ agonists did not increase CGZ- or TGZ-induced cell death, indicating that PPARγ agonists induced HeLa cell death independently of PPARγ. Moreover, ERK1/2 activation was observed at a CGZ concentration of 25 μM and a TGZ concentration of 35 μM, both of which induced cell death. To elucidate the role of ERK1/2 activated by the two PPARγ agonists, the effect of U0126, an inhibitor of ERK1/2, on PPARγ-agonist-induced cell death was examined. Treatment with 10 or 20 μM U0126 followed by CGZ or TGZ induced the down-regulation of ERK1/2 activity and a decrease in Bcl-2 expression accompanied by the collapse of mitochondrial membrane potential, which in turn significantly enhanced CGZ- or TGZ-induced apoptotic cell death. Our results suggest that PPARγ agonists are capable of inducing apoptotic cell death in HeLa cells independently of PPARγ and that inhibition of ERK1/2 activity offers a strategy to enhance the cytotoxicity of PPARγ agonists in the treatment of cervical cancer.

Abstract
OBJECTIVE To evaluate the impact of comorbid diabetes mellitus (DM) on prognoses among patients with cervical cancer. METHODS We analyzed cervical cancer outcomes in patients who treated in two hospitals retrospectively. Patients were divided into those with DM and those without. Clinicopathologic parameters, disease-free survival (DFS), and overall survival (OS) rates were evaluated. RESULTS Of the 494 patients, 50 had DM. These were more likely to be older than those in the non-DM group and their body mass index (BMI) was higher. They showed higher levels of tumor markers and had more combined diseases. They were less likely to have had surgical treatment. Among these patients, 12 (24%) experienced a recurrence (hazard ratio, HR, 1.484; 95% confidence interval, CI, 0.746-2.951). Differences in DFS did not show statistical significance. In the OS analysis, 11 (22%) in the DM group and 62 (14%) in the non-DM group died (HR, 1.239; 95% CI, 0.606-2.533). No statistically significant differences were also observed for cancer-specific death (HR, 1.246; 95% CI, 0.567-2.737). Those with DM and an adenocarcinoma tended to have an increased risk of dying compared with the non-DM patients with an adenocarcinoma (HR, 3.673; 95% CI, 0.990-13.625), but this difference was not statistically significant (p=0.0518). CONCLUSION Diabetes mellitus did not have an impact on the prognosis for patients with cervical cancers. In those with an adenocarcinoma, patients with diabetes tended to have an increased risk of dying compared with the non-DM group, but this difference was not statistically significant.

Abstract
Triple-negative breast cancer (TNBC) relapses more frequently than hormone receptor-positive subtypes and is often associated with poor outcomes. This retrospective study reviewed the pattern of distant metastasis with regard to survival in patients with TNBC. A total of 205 TNBC patients were analyzed. TNBC patients with lung metastases had the longest median post-metastatic OS (with 95% confidence interval) of 16.6 (10.3-22.9) months, followed by the bone, 16.3 (11.7-20.8) months, the liver, 8.9 (3.5-14.4) months, the pleura, 7.5 (2.8-12.3) months, and the brain, 4.3 (0.6-8.0) months. Kaplan-Meier plots indicated that TNBC patients with metastatic spread to brain, liver, and pleural had poorer post-metastatic OS rate than patients with lung metastases (p = 0.001, 0.004, and 0.029, respectively). Moreover, brain and liver metastases correlated significantly with poorer post-metastatic OS as compared to bone metastasis (p = 0.004 and 0.011, respectively). Route of first metastasis correlated significantly with survival of TNBC patients with brain metastases being the poorest survival indicator, followed by metastases to liver, pleura, bone, and lung.

Abstract
OBJECTIVE This study was to compare pregnancy outcomes between cerclage and expectant management in wemen with a dilated cervix. DESIGN Retrospective multicenter cohort study. SETTING Five hospitals of Catholic University Medical Center Network in Korea. POPULATION A total of 173 women between 14 0/7 and 29 6/7 weeks' gestation with cervical dilation of 1 cm or greater by digital examination. METHODS Pregnancy outcomes were compared according to cerclage or expectant management, with the use of propensity-score matching. MAIN OUTCOME MEASURES Primary outcome was time from presentation until delivery (weeks). Secondary outcomes were gestational age at delivery, neonatal survival, morbidity, preterm birth, and so on. RESULTS Of 173 women, 116 received a cerclage (cerclage group), and 57 were managed expectantly without cerclage (expectant group). Cervical dilation at presentation, and the use of amniocentesis performed to exclude subclinical chorioamnionitis differed between two groups. In the overall matched cohort, there was significant difference in the time from presentation until delivery (cerclage vs. expectant group, 10.6±6.2 vs. 2.9±3.2 weeks, p <0.0001). While there was no significant difference in the neonatal survival between two groups, there were lower neonatal morbidity as well as higher pregnancy maintenance rate at 28, 32, 34 and 37 weeks' gestation in the cerclage group, compared with the expectant group. CONCLUSION This study suggests that digital examination-indicated cerclage appears to prolong gestation and decrease neonatal morbidity, compared with expectant management in women with cervical dilation between 14 0/7 and 29 6/7 weeks.

Abstract
OBJECTIVE To investigate the potential susceptibility to the solute carrier family 11 member 1 (SLC11A1) gene polymorphisms of Korean patients with Behçet's disease (BD). METHODS Ninety-nine patients with BD and 98 controls were recruited. Analyses of three polymorphisms of the SLC11A1 gene [the 5'-promoter (GT)n, D543N and A318V] were performed, either by denaturing high-performance liquid chromatography for D543N and A318V or by using automatic DNA sequencing for the (GT)n. The genotypes and alleles between patients with BD and the controls were compared using the chi2 test and Yate's correction test. RESULTS No significant differences were found in the distribution of genotypes and alleles of the (GT)n polymorphism between BD patients and the controls. However, subjects with the allele 3 or the genotype allele 3/allele 3 of this polymorphism had a significantly lower risk of developing BD than those without this allele or genotype [allele: p = 0.029, pc = 0.039, odds ratio (OR) = 0.60, 95% confidence interval (CI) 0.37-0.95; genotype: p = 0.036, pc = 0.048, OR = 0.54, 95% CI 0.31-0.96]. In addition, the distributions of genotypes and alleles of D543N were similar between BD patients and controls (p>0.05). In the case of A318V, all of the BD patients and controls had a wild-type genotype. CONCLUSION The allele 3 and the genotype allele 3/allele 3 of the 5'-promoter (GT)n in the SLC11A1 gene may have a protective effect for the development of BD in the Korean population. Further studies in other populations are required to confirm our results.

Abstract
OBJECTIVE This study was performed to examine the influence of tumour necrosis factor-alpha (TNFalpha) promoter polymorphisms on disease susceptibility and clinical features of Behçet's disease (BD) and the association between TNFalpha polymorphisms and human leucocyte antigen (HLA)-B51. METHODS We examined 115 patients with BD and 114 healthy subjects. Six single nucleotide polymorphisms (SNPs) of the TNFalpha promoter at positions -1031, -863, -857, -308, -238, and -646 were analysed using automated sequencing. We compared the frequencies of alleles and genotypes in patients with BD and controls using the chi(2)-test or Fisher's exact test. Haplotype frequency was also assessed using the chi(2)-test. RESULTS We found no significant differences in the frequencies of polymorphic genotypes and alleles of the TNFalpha promoter region between BD patients and controls. The resulting haplotype frequencies of the BD patients were also not significantly different from those of controls. None of the TNFalpha promoter polymorphisms analysed here were associated with clinical features. Patients with the novel -646A allele of the TNFalpha promoter region were significantly associated with the expression of the HLA-B51 allele (p(corr) = 0.006), although this novel polymorphic allele was not associated with BD susceptibility. CONCLUSION The novel -646A TNFalpha allele was associated with the expression of HLA-B51 in Korean BD, although we found no genetic role of TNFalpha promoter polymorphisms in the susceptibility to BD. Further studies to examine the contributions of this gene polymorphism and HLA-B51 to the susceptibility to BD in large populations are required.

Abstract
Invasive pulmonary aspergillosis (IPA) is a serious and lethal complication among organ transplant recipients. This report described the clinical manifestations and treatment of IPA over a 28-year period. From January 1979 to December 2007, 3215 organ transplant patients (2954 kidney and 261 liver recipients) were enrolled in the study. Nine patients developed IPA (7 kidney and 2 liver recipients), yielding an incidence of 0.003% (9/3215). Five IPA patients (55.6%) were diagnosed by transbronchial lung biopsy or autopsy, and 3 (33.3%) by sputum culture study. One patient was diagnosed through clinical manifestations and observations of IPA characteristics on chest X ray. We used amphotericin B (n = 4; 44.4%), voriconazole (n = 2; 22.2%), or fluconazole (n = 1; 11.1%) as the primary antifungal agents, but 2 patients could not receive antifungal agents due to rapid disease progression and sequential mortality. This study showed a high mortality rate among IPA patients (55.6%; 5/9). Only patients who received early antifungal agent thereby after a prompt diagnosis recovered from IPA. This survival advantage warrants careful monitoring for invasive fungal infections after organ transplantation with immediate administration of antifungal agents or surgical intervention.

Abstract
AIMS To investigate the survival benefit and preoperative risk factors for hospital mortality of salvage surgery in esophageal cancer patients who had locoregional residual/recurrent tumor after definitive chemoradiotherapy. METHODS We retrospectively reviewed the esophageal cancer patients who presented at our hospital from 1997 to 2004. Forty-seven patients who had squamous cell cancer and developed locoregional recurrent/persistent disease after primary definitive chemoradiotherapy were elected. Twenty-seven of them received salvage esophagectomy (group 1) and the other 20 underwent non-operative treatment only (group 2). In order to assess the surgery-related mobility and mortality in group 1, 191 patients who received neoadjuvant chemoradiotherapy followed by operation during the same time period were also enrolled (group 3). RESULTS The 5-year overall survival of group 1 patients was 25.4%. In contrast, all of the patients in the group 2 died within 16.7 months. The difference was statistically significant (p=0.0029). In comparison with group 3, group 1 patients had significantly more surgery-related complications and hospital mortality. In univariate analysis for preoperative risk factors, a low albumin or hemoglobulin level was associated with high hospital mortality in group 1 (p=0.004 and 0.003, respectively). After multivariate analysis, only the low albumin level remained borderline significance. As for disease specific survival after salvage surgery, R0 resection was the only independent prognosticator (p=0.049). CONCLUSION Salvage surgery provides survival benefit in esophageal cancer patients with locoregional persistent or recurrent disease after primary definitive chemoradiotherapy. Preoperative albumin and hemoglobulin levels are associated with hospital mortality and may aid in selecting suitable patient for salvage surgery.

Abstract
OBJECTIVE To determine the prevalence of fibromyalgia (FM) in Korean patients with Behçet's disease (BD) and to evaluate the association between FM and clinical and psychological variables. METHODS Seventy patients with BD were examined for FM tender points and asked to complete a Korean version of the Fibromyalgia Impact Questionnaire (FIQ). Disease activity was measured using the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and a clinical activity score, which was calculated by summing the clinical manifestations. The State-Trait Anxiety Inventory (STAI) and Beck Depression Inventory (BDI) were used for psychometric scoring. RESULTS Twenty-six BD patients (37.1%) met the American College of Rheumatology criteria for FM. The patients who met the criteria for FM were more frequently female, less frequently employed, and less well educated. Age, disease duration, clinical manifestations, medication, and measures of disease activity did not differ between BD patients with and without FM. Nevertheless, BD patients with FM had higher STAI and BDI scores than did patients without FM (all p < 0.05). FM tender points were significantly correlated with the STAI and BDI, and not with disease activity variables. The FIQ scores were also strongly correlated with the STAI and BDI scores, and not with disease activity. CONCLUSION FM was very common among BD patients and was associated with the presence of anxiety and depression, and not with disease activity.

Abstract
OBJECTIVE There is strong evidence that Th1-type cytokines play an important role in the pathogenesis of Behçet's disease (BD). Interleukin (IL)-18 is a proinflammatory cytokine that mediates Th1-polarized immune responses, and elevated levels of IL-18 have been observed in the sera and bronchoalveolar lavage fluid of patients with active BD. Therefore, the aim of this study was to investigate the potential associations of two single nucleotide polymorphisms (SNPs) at positions -137 (G/C) and -607 (C/A) in the promoter region of the IL-18 gene with a susceptibility to BD in the Korean population. METHODS Ninety-eight patients with BD and 105 healthy controls were studied. All of the subjects were genotyped using sequence specific PCR. The genotypes and alleles between patients with BD and controls were compared using the chi2 test, together with Yate's correction where appropriate. Haplotype analysis was assessed using the EH program. RESULTS The genotype and allele distributions of the two SNPs did not differ significantly between patients with BD and controls. The haplotype frequencies of the IL-18 promoter polymorphisms were also similar between patients with BD and controls. However, the frequency of the GG genotype at position -137 was significantly higher in BD patients with ocular lesions than in those without ocular lesions (p = 0.026, pc = 0.048, OR = 4.1). CONCLUSION Although the IL-18 gene polymorphisms were not associated with a susceptibility to BD in the Korean population, the patients carrying the GG genotype at position -137 had a higher risk of developing the ocular lesions. Further studies in other populations are required to confirm these results.

Abstract
AIM Peripheral nerve injuries are commonly encountered clinical problems and often result in severe functional deficits. In the present study, the effects of treadmill running on the recovery rate of locomotor function and the expression of brain-derived neurotrophic factor (BDNF) mRNA following sciatic crushed nerve injury in rats were investigated. METHODS EXPERIMENTAL DESIGN Comparative investigation was performed over 14 days. SETTING Experimental animal laboratory. PARTICIPANTS 24 male Sprague-Dawley rats weighing 200+/-10 g. Animals were randomly assigned into 3 groups: the sham-operation group, the sciatic nerve injury group, and the sciatic nerve injury and running group. INTERVENTIONS The right sciatic nerve was crushed for 30 s using a surgical clip. Rats of the running group were made to run on a treadmill for 30 min once a day for 12 consecutive days. MEASURES Functional recovery was analyzed using a walking track analysis which can be quantified with the sciatic function index (SFI) and BDNF mRNA expression was analyzed using reverse transcription-polymerase chain reaction (RT-PCR). RESULTS Sciatic crushed nerve injury showed characteristic gait changes showing decrease of SFI value and treadmill running significantly enhanced the SFI value. The level of BDNF mRNA expression was increased following sciatic crushed nerve injury and treadmill running significantly suppressed the sciatic nerve injury-induced increment of BDNF mRNA expression. CONCLUSIONS It can be suggested that treadmill running after peripheral nerve injury is effective in the functional recovery by inhibition on the over-expression of BDNF mRNA.

Abstract
OBJECTIVE To investigate the degree of ossification and the frequency of ankylosis between the atlas and the dens of the axis in patients with longstanding ankylosing spondylitis (AS), to assess radiological involvement of the cervical spine, and to determine their correlations with structural severity and clinical variables, including neurological abnormalities. METHODS In 61 AS patients with disease duration over 7 years, the findings of conventional radiographs were graded by the Bath Ankylosing Spondylitis Radiology Index (BASRI), and the ossification levels between the atlas and the dens and the severity of zygapophyseal (ZA) joint lesions were scored using multislice CT. Neurological examinations and somatosensory evoked potentials (SSEP) were performed by neurologists. RESULTS According to the BASRI, 50 patients (82.0%) had radiological changes of the cervical spine > or = score 1. Thirty-seven patients (60.6%) revealed a certain extent of the atlantodental ossification, and the presence of partial or complete atlantodental ankylosis was seen over 30% of the patients. The BASRI-cervical spine score and the atlantodental ossification levels correlated with disease duration. ZA involvement was observed in 49 patients (80.3%), including 23 with ZA fusion (37.7%). Although 4 of 11 patients with atlantoaxial subluxation showed abnormal SSEP none had significant neurological complications. This might be attributed in part to atlantodental ankylosis and ZA fusion. Finally, ossifications of the anterior and posterior longitudinal ligaments were found 26.2 and 29.5%, respectively. CONCLUSION Cervical spine involvement and atlantodental ossification or ankylosis appear to be common in patients with longstanding AS, and to be particularly more severe in patients with a longer disease duration.

Abstract
OBJECTIVE Recently we have proposed a modified set of criteria to settle the questions raised regarding the International Study Group (ISG) criteria for Behçet's disease (BD). The aim of the present study was to validate the two pre-existing criteria sets commonly used in Korea, the ISG criteria and the criteria of the Behçet's Disease Research Committee of Japan (Japanese criteria), as well as the proposed modified criteria. METHODS The study population included 155 consecutive patients with BD and 170 controls with non-Behçet's rheumatic diseases. Detailed data for all of the subjects were recorded prospectively by the participating physicians on a standard form that listed the clinical features of BD. The sensitivity, specificity, and accuracy of each set of the criteria were measured. RESULTS Of the three criteria sets employed, the modified criteria were the most accurate, with an accuracy of 96.3%. The ISG criteria often failed to classify the following patients with BD: patients with only oral and genital ulcerations, certain patients with intestinal ulcerations, patients who did not manifest oral ulcerations, and patients with acute disease but fewer than three recurrent oral ulceration relapses in a 1-year period. The Japanese criteria also failed to categorize the following patients with BD: patients with oral and genital ulcerations, and patients with oral ulcerations, skin lesions, and a positive pathergy reaction. In addition, the Japanese criteria misclassified some of the control subjects with non-Behçet's uveitis as having BD. CONCLUSIONS The results of this study suggest that there are some points that need to be reconsidered in the clinical application of the two pre-existing sets of criteria. Although the modified criteria were the most accurate, further validation studies will be required in other ethnic populations.

Abstract
OBJECTIVE To assess potential associations between Korean Behçet's disease (BD) or other rheumatic diseases with vasculitis and two polymorphisms of the endothelial nitric oxide synthase (eNOS) gene, which include the Glu298Asp polymorphism in exon 7 and a variable number of tandem repeats (VNTR) polymorphism in intron 4. METHODS 65 patients with BD, 27 with rheumatic diseases with vasculitis, and 80 controls were studied. Analyses of the Glu298Asp polymorphism in exon 7 and VNTR polymorphism in intron 4 of the eNOS gene were made by the polymerase chain reaction (PCR)-restriction fragment length polymorphism technique and PCR genotyping, respectively. Additionally, HLA-B51 typing was performed in the BD group and controls by a two step PCR sequence-specific primers method. RESULTS Significant differences in Glu298Asp genotype frequencies were found between the BD or vasculitis groups and the controls (BD group v controls: p(corr)=0.006; vasculitis group v controls: p<0.001). The Asp298 frequency was much higher in the BD and vasculitis groups than in the controls. Even after stratification of the BD group based on the results of HLA-B51 testing, a significant association of the Glu298Asp polymorphism was still found (p=0.002, Mantel-Haenszel weighted odds ratio 4.3, 95% confidence interval 1.7 to 10.9). Distribution of the genotype frequencies in two eNOS gene polymorphisms was similar in connective tissue diseases-associated vasculitis and primary vasculitic syndromes. In contrast, distribution of alleles and genotypes of VNTR polymorphism did not differ between BD or vasculitis groups and the controls. CONCLUSION The Glu298Asp polymorphism in exon 7 of the eNOS gene seems to be a susceptibility gene for Korean BD and other rheumatic diseases.

Abstract
OBJECTIVE The prevalence of Th-2 cell-mediated diseases, such as atopic diseases, has been noted to be low in Th-1 cell-mediated diseases. This study was undertaken to assess the prevalence of atopy and atopic diseases in Behçet's disease (BD), a Th-1 cell-mediated disease, and to investigate the clinical association between the atopy and the development of severe manifestations in BD. METHODS We examined 70 consecutive BD patients and 113 controls without BD or other inflammatory rheumatic diseases. The cumulative history of severe manifestations in BD patients was investigated during the disease course. A skin prick test was performed in all the subjects, and atopy was defined as present when the size of one or more allergen-induced wheals was equal to or larger than that caused by histamine. Atopic diseases were defined as present when there were relevant responses for atopic diseases on the questionnaires in the subjects with atopy. In addition, serum IgE levels and peripheral blood eosinophil counts were measured. RESULTS The prevalence of atopy and atopic diseases was significantly lower in BD patients than in controls. Other atopy parameters, such as serum IgE levels and peripheral blood eosinophil counts, were also significantly lower in BD patients when compared with controls. However, atopy, serum IgE levels, and peripheral blood eosinophil counts did not differ significantly between BD patients with and without severe manifestations. CONCLUSION The prevalence of Th-2 cell-mediated conditions, such as atopy and atopic diseases, appeared to be lower in BD, a Th-1 cell-mediated disease. In addition, a Th-1 and Th-2 balance may not influence the development of severe manifestations in BD.

Abstract
OBJECTIVE To investigate the relationship between fasting glucose and 2 h glucose with percentage of Hawaiian ancestry and ethnic admixture. DESIGN Cross-sectional epidemiological study of type 2 diabetes and heart disease risk factor prevalence among Native Hawaiians. SUBJECTS A total of 578 Native Hawaiians residing in two rural communities were examined between 1993 and 1996. Sample sizes in statistical analyses varied due to missing data and selection criteria based on ethnic ancestry. MEASUREMENTS Percentage of Hawaiian ancestry and non-Hawaiian ethnic admixture, assessed by self-report. Fasting and 2 h post glucose challenge plasma glucose levels. Anthropometric measures (height, weight, waist and hip circumferences). Self-report of diet and physical activity. Medical history. RESULTS Increased Hawaiian blood quantum was significantly associated with increased fasting glucose (P=0.0047), increased body mass index (BMI; P<0.0001), waist-to-hip ratio (WHR; P=0.0103), and age (P<0.0001), but not with leisure time physical activity and total dietary caloric intake. This association was attenuated after adjusting for BMI and WHR, but not by age-adjustment alone. However, when the effects of descent from other ethnic groups was examined in a subset of participants, full-Hawaiians had significantly higher fasting glucose concentrations (7.28 mmol/l) than part-Hawaiians after adjustments for age, gender, BMI and WHR. In contrast, part-Hawaiians of predominantly Asian ancestry had the highest 2 h glucose concentrations (7.62 mmol/l). CONCLUSION These results suggest that ethnic admixture may be an important, but extremely complex, factor concerning the high prevalence of type 2 diabetes observed among this population. The complexity of this relationship may have obscured the relationship between ancestry and glucose tolerance in earlier observations of this population.

Abstract
The aim of this study was to determine the distribution of the FcgammaRlla and FcgammaRIIIa polymorphisms and their association with clinical manifestations in Korean lupus patients. Three hundred SLE (systemic lupus erythematosus) patients (48 male, 252 female) meeting 1982 ACR criteria and 197 Korean disease-free controls were enrolled. Genotyping for FcgammaRlla 131 R/H and FcgammaRIIIa 176 F/V was performed by PCR of genomic DNA using allele-specific primers and the FcgammaRIIIa genotype was confirmed by direct sequencing of PCR product in some cases. There was significant skewing in the distribution of the three FcgammaRIIa genotypes between the SLE and the controls (P=0.002 for R/R131 vs R/H131 and H/H131, OR 2.5 (95% Cl 1.4-4.5), but not in FcgammaRIIIa genotypes. FcgammaRIIa-R allele was a significant predictor of lupus nephritis, as compared with SLE patients without nephritis (P=0.034 for R131 vs H131, OR 1.4 (95% Cl 1.03-1.9)), but proliferative nephritis (WHO class III and IV) was less common in patients with FcgammaRlla-R/R131 and in FcgammaRIIa-R allele. In 300 SLE patients, high binding allele combination H131/V176 was less common in SLE with nephritis than in SLE without nephritis. Hemolytic anemia was less common in R131/F176 allele combination among four FcgammaRIIa/FcgammaRIIIa allelic combinations. Male SLE patients showed a higher frequency of renal involvement, serositis, thrombocytopenia, malar rash and discoid rash than female SLE, and male SLE had a higher frequency of FcgammaRIIa-R/R131 or R131-allele than male controls, but FcgammaRIIa or FcgammaRIIIa genotypes had no association with renal involvement in male SLE patients. FcgammaRIIa-H/H131 showed a higher frequency of hemolytic anemia and less pulmonary complications in male SLE. Female SLE patients showed higher frequency of any hematologic abnormality, lymphopenia, anticardiolipin antibody (+) and anti-Ro antibody (+) than male SLE, and had earlier onset of first symptoms. There was no skewing in FcgammaRIIa or FcgammaRIIIa genotypes between female SLE and female controls, but FcgammaRIIa-R131 allele showed skewing between female SLE with nephritis and female SLE without nephritis. The age at onset of thrombocytopenia was earlier in FcgammaRIIa R/R131 among three FcgammaRIIa genotypes, and serositis in FcgammaRIIIa-F/F176 among three FcgammaRIIIa genotypes. FcgammaRIIa-R131 homozygote was a major predisposing factor to the development of SLE and FcgammaRIIa-RI31 homozygote and R131 allele were a predisposing factor, and H131/V176 was a protective allele combination in lupus nephritis. In contrast to other ethnic patients, in our study cohort, clinical manifestation was different between male and female, and FcgammaRIIa and FcgammaRIIIa showed somewhat different clinical associations between the genders.

Abstract
BACKGROUND A phase II clinical trial was performed to evaluate the activity and toxicity of bimonthly cisplatin and weekly 24-h infusion of high-dose 5-fluorouracil and leucovorin in patients with advanced gastric cancer. PATIENTS AND METHODS From September 1997 to March 1998, 23 chemo-naive patients of advanced gastric cancer were enrolled in this study. The regimen consisted of weekly 24-h infusion of 5-FU (2,600 mg/m2) and LV 150 mg and bimonthly cisplatin (25-50 mg/m2) bolus for 12 weeks followed by a 2-week break. RESULTS There were 10 male and 13 female patients with a median age of 52 years. A total of 428 chemotherapy treatments were given with a mean of 11. Seventeen patients were evaluable for response. There were 41% (7/17) partial response, 18% (3/17) stable disease and 41% (7/17) progressive disease. The grade III or IV toxicity included anorexia 35% (8/23), fatigue 26% (6/23), vomiting 17% (4/23) and mucositis 9% (2/23). One patient developed perforated duodenal stump after chemotherapy. One patient died of hyperammonemia-related coma. The median times to disease progression and overall survival were 3.5 and 7 months, respectively. CONCLUSIONS This regimen showed modest activity against gastric cancer. However, there was no survival advantage and there was greater toxicity than with weekly high-dose 5-FU-LV alone.

Abstract
Porcine proliferative enteropathy(PPE) is an enteric disease been caused by Lawsonia intracellularis. It has become one of the critical problems in the pig industry. To investigate the prevalence of PPE in Korea, serum samples of 828 pigs from 65 herds were tested using indirect immunofluorescence antibody technique(IFA). The infection rate in individual pigs varied from 44 to 69%, whereas 100% in pig farms. The infection frequency was 57, 44.9, and 59.4% according to age respectively. Administration of tylosin in feed at a concentration of 110 ppm for 14 days reduced the infection rate of the farms. These data indicated that the high prevalence of PPE may be controlled by tylosin.
