OBJECTIVE: The purpose of this retrospective study was to evaluate the effect of neoadjuvant chemotherapy followed by radical surgery compared with conventional radical surgery in stage Ib1 cervical cancer as to operative complications, the rate of lymph node metastasis, recurrence and overall five-year survival rates. METHODS: The study materal (98 cases of stage Ib1 cervical cancer) was divided into two groups; The one group was neoadjuvant chemotherapy (Cisplatin + 5-FU) followed by radical surgery (n = 41) and the other was the conventional radical surgery (n = 57) group. Reviewing records of operative and pathological reports and clinical findings, the outcome was statistically analyzed and compared. RESULTS: As to the complication, bladder dysfuntion was more frequent in neoadjuvant chemotherapy group, statistically significant.(43.9% vs 22.8%, P=0.034). No significant difference was found in the incidence of lymphnode metastasis (17% vs 17.5%, P=0.779) and overall five year survial rates(85.3% vs 87.7%, P=0.735). CONCLUSION: No benefical effect of neoadjuvant chemotherapy could be found on stage Ib1 cervical cancer in this retrospective study. However, well controlled longterm prospective study will be need to get firm conclusion.

OBJECTIVES: Many medication errors can occur when ordering and dispensing medicine in hospitals. The clinical decision support system (CDSS) is widely used in an effort to reduce medication errors. This study focused on the evaluation of user satisfaction with the CDSS for medication at a university hospital. Specifically, this study aimed to identify the factors influencing user satisfaction and to examine user requirements in order to further improve user satisfaction and drug safety. METHODS: The study was based on survey data from 218 users (103 doctors, 103 nurses, and 15 pharmacists) at a university hospital that uses the CDSS. In order to identify the factors influencing user satisfaction with the CDSS, a multiple linear regression was performed. In order to compare the satisfaction level among the professional groups, an analysis of variance (ANOVA) was performed. RESULTS: The reliability of information, decision supporting capability, and departmental support were significant factors in influencing user satisfaction. In addition, nurses were the most satisfied group, followed by pharmacists and doctors according to the ANOVA. Areas for further improvement in enhancing drug safety were real time information searching and decision supporting capabilities to prevent adverse drug events (ADE) in a timely manner. CONCLUSIONS: We found that the CDSS users were generally satisfied with the system and that it complements the nationwide drug utilization review (DUR) system in reducing ADE. Further CDSS evaluation in other hospitals is needed to improve user satisfaction and drug safety.

Malignant deciduoid mesothelioma is a rare malignant neoplasm occurring in the peritoneum of young women. We report a case of malignant deciduoid mesothelioma that occurred in the omentum of a 47-year-old woman. The patient had never exposed to asbestos and had no history of cesarean section. The lesions were multiple infiltrative nodules affected the peritoneal cavity, omentum, and surface of the uterus with both ovaries. Microscopically, the nodules were composed of mesothelial cells similar to decidual cells

OBJECTIVES: This study presents the information system for Pusan National University Hospital (PNUH), evaluates its performance qualitatively, and conducts economic analysis. METHODS: Information system for PNUH was designed by component-based development and developed by internet technologies. Order Communication System, Electronic Medical Record, and Clinical Decision Support System were newly developed. The performance of the hospital information system was qualitatively evaluated based on the performance reference model in order to identify problem areas for the old system. The Information Economics approach was used to analyze the economic feasibility of hospital information system in order to account for the intangible benefits. RESULTS: Average performance scores were 3.16 for input layer, 3.35 for process layer, and 3.57 for business layer. In addition, the cumulative benefit to cost ratio was 0.50 in 2011, 1.73 in 2012, 1.76 in 2013, 1.71 in 2014, and 1.71 in 2015. The B/C ratios steadily increase as value items are added. CONCLUSIONS: While overall performance scores were reasonably high, doctors were less satisfied with the system, perhaps due to the weak clinical function in the systems. The information economics analysis demonstrated the economic profitability of the information systems if all intangible benefits were included. The second qualitative evaluation survey and economic analysis were proposed to evaluate the changes in performance of the new system.

PURPOSE: The purpose of the present study was to evaluate the potential association of the G1691A mutation of factor V (factor V Leiden), which is a main causative factor of activated protein C resistance leading to intravascular coagulation, with osteonecrosis (ON) of the femoral head. MATERIALS AND METHODS: Genomic DNA was extracted from peripheral blood leukocytes of 116 consecutively identified patients with nontraumatic ON of the femoral head and 59 healthy controls. The region in exon 10, that encodes an APC cleavage site in factor V gene, was amplified by polymerase chain reaction (PCR) with use of the 2 primers (Korea Biotech Inc., Daejeon): 5'-GGA ACA ACA CCA TGA TCA GAG CA-3' (forward primer) and 5'-TAG CCA GGA GAC CTA ACA TGT TC-3'(reverse primer). Amplified product was subjected to MnlI restriction enzyme digestion and resulting fragments were separated by electrophoresis on 3% agarose gel. The homozygous and heterozygous patterns of DNA fragments of 1691G-A mutation in the factor V gene was investigated. RESULTS: The prevalence of factor V Leiden was 0% in the patients group and in the control group. CONCLUSIONS: The data suggested that thrombophilia by the G1691A mutation of factor V (factor V Leiden) was less likely to be associated with the development of ON of the femoral head in Koreans.

Synovial fluid (SF) aspiration cytology is a useful diagnostic tool. For patients with gouty arthritis, the diagnosis is confirmed by the presence of monosodium uric acid (MSU) crystals in the SF, and these crystals are long, pointed ended and needle-shaped and they show strongly negative birefringence. Sometimes, it is difficult to diagnosis between gouty arthritis and other type of inflammatory arthritis. We experienced two unusual cases of gouty arthritis that we performed SF analysis for. The first patient was a 35 year old male who presented with relatively typical clinical symptoms with hyperuricemia, but the SF showed acute inflammatory cells without crystals on light microscopy. Only a few suspected crystals of MSU were identified on polarizing microscopy. The second patient was a 45 year old male who presented with atypical symptoms and pain and swelling of the left ankle and knee joint for 3 weeks. The uric acid level in the serum and urine was increased, but not over the normal limit. However, on light and polarizing microscopy, there were numerous MSU crystals in the SF. Conclusively, in some cases of gouty arthritis, the crystals are not identified on light microscopy or the uric acid level is not dramatically increased. So, the polarizing microscopy, the clinical information and the laboratory findings are all included in the work-up when evaluating the SF cytology of arthritis patients.

Uterine torsion, which most often occurs during pregnancy, is rare. Torsion of a nongravid uterus is extremely rare and is associated with pelvic adhesions, uterine leiomyomas, or uterine anomalies. We experienced a case of uterine torsion, with a huge subserosal leiomyoma and multiple intramural leiomyomas, in a postmenopausal woman, one that showed the most extreme degree of rotation among the known cases of uterine torsion. Necrosis of the uterus and both adnexae was observed. A total abdominal hysterectomy with a bilateral salpingo-oophorectomy was performed. We present this case with a brief review of the relevant literature.

Lysophosphatidic acid (LPA) is a bioactive phospholipids and involves in various cellular events, including tumor cell migration. In the present study, we investigated LPA receptor and its transactivation to EGFR for cyclooxygenase-2 (COX-2) expression and cell migration in CAOV-3 ovarian cancer cells. LPA induced COX-2 expression in a dose-dependent manner, and pretreatment of the cells with pharmacological inhibitors of Gi (pertussis toxin), Src (PP2), EGF receptor (EGFR) (AG1478), ERK (PD98059) significantly inhibited LPA- induced COX-2 expression. Consistent to these results, transfection of the cells with selective Src siRNA attenuated COX-2 expression by LPA. LPA stimulated CAOV-3 cell migration that was abrogated by pharmacological inhibitors and antibody of EP2. Higher expression of LPA2 mRNA was observed in CAOV-3 cells, and transfection of the cells with a selective LPA2 siRNA significantly inhibited LPA-induced activation of EGFR and ERK, as well as COX-2 expression. Importantly, LPA2 siRNA also blocked LPA-induced ovarian cancer cell migration. Collectively, our results clearly show the significance of LPA2 and Gi/Src pathway for LPA-induced COX-2 expression and cell migration that could be a promising drug target for ovarian cancer cell metastasis.

OBJECTIVE: To study the relationship between serum human papillomavirus (HPV) deoxyribonucleic acid (DNA) and clinicopathologic prognostic factors and the clinical usefulness of serum HPV 16 DNA in cervical cancer patients. METHODS: All the patients were treated at our institution, from January, 2002 to February, 2007. DNA extracted from serum of 17 patients with HPV 16 infected carcinoma in situ and 65 patients with HPV 16 infected squamous cell carcinoma of the uterine cervix (stage IA-IIIB) were examined for HPV 16 DNA using polymerase chain reaction with types 16 specific E6 primer. Clinicopathological parameters were obtained from medical records, and the relationship between the discrete variables and serum HPV 16 DNA status were evaluated. RESULTS: HPV 16 DNA was not detected in serum from all patients with carcinoma in situ. However, among the 65 patients with HPV 16 infected squamous cell carcinoma of the uterine cervix, we detected 17 HPV 16 DNA positive samples (26.2%) in serum. Positive HPV 16 DNA in serum was correlated with age (P=0.0071), serum squamous cell carcinoma (SCC) antigen (P=0.0034), tumor size (P=0.0029), clinical stage (P<0.0001), deep stromal invasion (P=0.0048), resection margin positivity (P=0.0008), and pelvic lymph nodal metastasis (P=0.0040). CONCLUSION: The serum HPV 16 DNA in patients with cervical cancer was correlated with poor prognostic factors that need adjuvant treatment.
