Background: s/Aims: This study was performed to reveal the usefulness of the trabecular bone score (TBS) in assessing bone strength in patients with ankylosing spondylitis (AS) in comparison with dual-energy X-ray absorptiometry (DXA) methods. Methods: A total of 215 AS patients (75.8% male) were enrolled from a single university hospital in Korea. Demographic and clinical information were assessed. Patients completed X-rays of the cervical and lumbar spine (L-spine), and spinal ankyloses were quantified using the modified Stoke AS Spine Score (mSASSS). Hip, anteroposterior and lateral L-spine bone mineral density (BMD) and TBS were assessed by DXA methods. Clinical characteristics and bone strength measurement results were compared between male and female AS patients. The accuracy of each bone strength evaluation method in predicting Fracture Risk Assessment Tool (FRAX) scores indicating moderate or higher fracture risk was compared by receiver operating characteristic curves in patients aged ≥ 40 years. Correlations between each bone strength measurement method and mSASSS were examined. Results: Male patients showed higher mSASSS and less prevalent peripheral joint involvement compared to female patients (p < 0.05). TBS, hip BMD, and L-spine lateral BMD showed comparably high areas under the curve (AUCs) for predicting FRAX-major osteoporotic fractures (MOF) ≥ 10% (AUC ranged 0.72 to 0.76). TBS negatively correlated with mSASSS in both male and female patients (p < 0.01). Conclusions TBS could predict the risk of MOF and is not influenced by spinal osteoproliferation in AS patients, even in those with advanced spinal changes.

PURPOSE: The impact of obesity on the surgical outcomes of Asian patients undergoing laparoscopic colon surgery is not clear. The purpose was to evaluate the outcome of laparoscopic surgery in obese Asian patients with colon cancer.METHODS: We retrospectively reviewed the prospectively collected data of 1,740 consecutive patients who underwent laparoscopic surgery for colon cancer between January 2008 and December 2010. Patients were classified according to the categories proposed by the International Obesity Task Force, Non-obese (body mass index [BMI]<25.0 kg/m2), Obese-I (BMI, 25.0–29.9 kg/m2), and Obese-II (BMI≥30 kg/m2). Surgical outcomes, including open conversion, operative time, and postoperative hospital stay, were compared in the Non-obese, Obese-I, and Obese-II patients.RESULTS: Of the 1,192 patients in the study, 812 (68.1%), 360 (30.2%), and 20 (1.7%), were classified as Non-obese, Obese-I, and Obese-II, respectively. The Obese-II group had higher conversion rates (10.0% vs. 3.6% and 1.6%, P=0.008) and, longer operative times (180.35 vs. 162.54 and 147.84 minutes, P<0.001) than the Obese-I and Non-obese group. However, the other postoperative outcomes were not significantly different. The overall survival and disease-free survival were not significantly different between groups (P=0.952). Multivariate analysis showed that the independent risk factor for conversion were BMI, total operative time, previous operative history, and cancer perforation.CONCLUSION: The outcomes of laparoscopic colon surgery in obese patients are similar to those of non-obese patients, offering all the benefits of a minimally invasive approach. However, the conversion rate was higher in obese patients. It is therefore very important for surgeons to be aware of these risks during laparoscopic colon surgery in obese patients.

PURPOSE: The purpose of this study was to evaluate the early and midterm results of superficial femoral artery (SFA) stenting with self-expanding nitinol stents and to identify the factors affecting patency. MATERIALS AND METHODS: SFA stenting was performed in 165 limbs of 117 patients from January 2009 to December 2013. Patients were followed-up for the first occurrence of occlusion or stenosis based on computed tomography and duplex scan results and a decrease in ankle brachial index of >15%. RESULTS: During the follow-up period (mean, 15.3+/-3.2 months), no early thrombotic reocclusions occurred within 30 days, but in-stent restenosis developed in 78 limbs. The primary patency rates at 6, 12, 18, and 24 months were 78%, 66%, 42%, and 22%, respectively, and the secondary patency rates were 85%, 72%, 58%, and 58%, respectively. TASC II C or D lesions, stent length >8 cm, number of patent tibial arteries and diabetes were significantly associated with reintervention. CONCLUSION: The midterm results of stenting for SFA occlusive disease were disappointing because the primary and secondary patency rates at two years were 22% and 58%, respectively. Reintervention after SFA stenting remains a major problem, particularly in patients with diabetes mellitus or long TASC II C or D lesions.

The aim of this study was to investigate the acute oral toxicity of fermented Scutellariae Radix (JKTMHGu-100) in rats and dogs. JKTM-HGu-100 was orally administered at a dose of 2,000 mg/kg in Sprague-Dawley rats. An escalating single-dose oral toxicity test in beagle dogs was performed at doses of 500, 1000, and 2000 mg/kg with 4-day intervals. Clinical signs, changes in body weight, mortality, and necropsy findings were examined for 2 weeks following oral administration. No toxicological changes related to the test substance nor mortality was observed after administration of a single oral dose of JKTM-HGu-100 in rats or dogs. Therefore, the approximate lethal dose (LD) for oral administration of JKTMHGu-100 in rats was considered to be over 2,000 mg/kg, and the maximum tolerance doses (MTDs) in rats and dogs were also estimated to be over 2,000 mg/kg. These results indicate that JKTM-HGu-100 shows no toxicity in rodents or non-rodents at doses of 2,000 mg/kg or less.

BACKGROUND/AIMS: The HER-2/neu protein is involved in normal cell proliferation and tissue growth because it is extensively homologous and related to epidermal growth factor receptor. As a prognostic marker, HER-2/neu is used to forecast the clinical course and poor outcome in breast cancer. As a predictive marker, HER-2/neu is used to predict the therapeutic response to adjuvant chemotherapy and endocrine therapy in breast cancer. In this study, we investigated the relationships between clinical and pathologic characteristics of tumor and prognosis according to the HER-2/neu expression in colon cancer. This study was conducted for the future introduction of Herceptin(r) therapy for colon cancer patients. METHODS: Overexpression of HER-2/neu was examined by semiquantitative standardized immunohistochemical staining kit in 88 patients with colon cancer. The patients underwent curative surgery at the Kangbuk Samsung Hospital. RESULTS: Overexpression of HER-2/neu was detected in 11 (12.5%) of 88 patients. Tumors with positive HER-2/neu staining showed a tendency for higher rates of nodal metastasis and poor mean survival (1,646 +/- 269 vs 2,631 +/- 141 days) and 5-year survival (65.5% vs 78.9%). CONCLUSIONS: Tumors with positive HER-2/neu staining showed a tendency for higher rates for nodal metastasis and poor clinical survival rate.

BACKGROUND/AIMS: The clinical usefulness of urinary trypsinogen-2 dipstick test is still in controversy. We evaluated the usefulness of urinary trypsinogen-2 dipstick test in patients with acute pancreatitis. METHODS: Urinary trypsinogen-2 dipstick test was prospectively performed in 50 patients with acute pancreatitis, 50 patients with non-pancreatic abdominal pain, and 50 healthy controls. RESULTS: On admission, urinary trypsinogen-2 dipstick test was positive in 36 of 50 patients with acute pancreatitis (sensitivity, 72%) and in 4 of 50 patients with non-pancreatic abdominal pain (specificity, 92%). On the other hand, it was all negative in controls. The sensitivity and specificity of serum lipase were 78% and 94%, respectively. At 24 hours after admission, the positive rate of urinary trypsinogen-2 dipstick test rose from 72% to 94% (p=0.02). The results of urinary trypsinogen-2 dipstick test was positive in 14 of 15 patients with severe pancreatitis and 22 of 35 patients with mild pancreatitis according to the criteria by Atlanta International Symposium, 1992. CONCLUSIONS: Urinary trypsinogen-2 dipstick test is comparable to serum lipase in diagnosing acute pancreatitis. Delayed measurement and severe pancreatitis are more likely to yield positive results with urinary trypsinogen-2 dipstick test. Thus, we suggest that the cut-off value of urinary trypsinogen-2 dipstick test should be lowered to increase its sensitivity.

Ischemic colitis generally develops in the elderly patients with concomitant cardiovascular condition, diabetes mellitus, and renal insufficiency. This disease predominently occurs in the left colon, particularly splenic flexure and sigmoid colon. The most frequent symptoms include abdominal pain, diarrhea, alteration in bowel functions and hematochezia. Blood loss is usually minimal in most patients. Herein, we report a case of ischemic colitis which developed on ascending colon with massive bleeding. A 48-year-old man was admitted because of massive lower gastrointestinal bleeding for 7 days. He has underwent hemodialysis for thirteen years. Colonoscopy showed a circular ulcer on the ascending colon with partial stenosis and mass-like oozing lesion distal to the stenotic area. We performed right hemi-colectomy. Grossly, colon showed shallow ulceration and congested ileocecal valve coated with hemorrhage. Microscopically, ulcer bed showed thickened and fibrotic submucosa which had nearly obliterated atherosclerotic vessels.

BACKGROUNDS: The education by the family physician. is important for more practical primary care medicine education. In this study, we try to know the presnent state of education and the future and the number of education resource and how to multiply this resource. METHODS: we have got the list of family physicians who have their clinic in Seoul by the help of the Korean Academy of Family Medicine. And we performed telephone questionary. We also asked the demographic factors RESULTS: 134 persons were asked questionary by the telephone. 17persons were joining in education. Trainee by the 3rd grade hospitals was the major, the next was by 2nd grade hospital, and doctors who did not have the training. 14 persons have begun education by asking of the training hospital, 3 persons wanted it, but none thought it beneficial to them. 44 persons wanted to join education in the future, and there was no difference between the 3rd and the 2nd grade hospital trainee. CONCLUSION: There was no difference between the 3rd and 2nd grade hospital trainee but 2nd grade hospital trainee was less joining than the 3rd. This shows that the 2nd grade hospital trainee can be the good pool of the future education if there are adequate supply. So many adequate supply is necessary.

A computerized hospital equipment utilization review system has been developed and implemented in a tertiary care utilization hospital in order to provide real-time equipment utilization with income information to be used in budgeting and strategic planning. Among various hospital fixed and clinical equipment, 283 (purchase price over US$15,000 per unit) were selected initially for utilization review. The application was written in Power Builder which was then loaded on Pentium client or on-line service. The data base management and statistical transactions were done by Oracle v 7.3.4 on NUMA Q2000 server. The utilization and associated income information of operating tables and other clinical equipment were automatically collected from physician order information in the hospital information system. Those information on other equipment which (lid not have direct utility information linked to physician order entry in the hospital information system were manually entered by users .Various utilization reports can be generated by users through computer menus; reports include name of equipment, using department, purchase price and year, frequency of use for inpatients and outpatients separately, income generated by such usage, and etc. The out put can also be generated by department, by instrument. by any interval as selected. The automated hospital equipment utilization review system has been developed and used since March, 2000 and is proven to he an essential tool for the hospital budget planners and managers. The outcome has been increasingly satisfactory.
