Osteochondromadevelop most commonly at distal femur, proximal humerus and proximal tibia, but the rib osteochondroma was reported less commonly. In this report, scapular snapping syndrome complicated by adventitious bursa and soft tissue pseudotumor surrounding the osteochondroma of the 6th rib body was treated successfully by surgical excision of them. We report this rare case with reviewing the relevant literature.

In case of submucosal tumor, adenoma and atypism, we can't frequently use the snare polypectomy for treatment of them. Adenoma and atypism are premalignant, so other therapeutic modalities are necessary for resection of them. We have perfortned endoscopic mueosectomy such as strip biopsy, and "O"ring ligation on various mucosal lesions of upper GI tract in 23 patients(11 men, l2 women) from June 1993 to December l994. Fourteen patients wbo had adenoma were followed up endoscopically for 6 months to 24 months(mean: 14 months). The results were as follows: 23 patients(27 lesions) were enrolled in this study. Mean age was 50.3(range 32-74 years). The method of mucosectomy was strip biopsy in 19 cases(21 lesions), and "O"ring ligation in 4 cases(6 lesions). The rate of complete resection was 88.9%. If adenomas were resected incompletely, we added a laser therapy. There was no recurrence except a case in which carcinoma was detected on the other site during follow-up. No serious compication occurred such as massive bleeding or perforation. Based on the above results, the endoscopic mucosectomy is considered to be a safe and effective modality in the treatment of the flat polyps of upper GI tract and could be used for prevention of gastric cancer.

Midazolam is a new water soluble benzodiazepine which used to induce anesthesia. The drug possesses properties similar to those of benzodiazepines(sedative, anxiolytic, anticonvulsant, muscle-relaxant) and has low toxicity compared with thiopental which is world-wide used for induction agent. Midazolam is characterized by slow onset of action, more gradual effects on circulation, low frequency of thrombophlebitis and greater degree of antegrade amnesia. Because of these characteristics midazolam is used as an alternative induction agent. As an induction agent, in order to evaluate the properties of midazolam compared with thiopental, 60 patients were divided into 2 groups. Group I, thiopental 5 mg/kg induction group; Group II, midazolam 0.15mg/kg induction group. Systolic and diastolic blood pressure, pulse rate, induction time and recovery time were measured in each group. Frequency of the throm bophlebitis, retrograde and antegrade amnesia were evaluated. In group I, systolic blood pressure decreased significantly and pulse rate increased signifi-cantly. In group II, diastolic pressure decreased significantly and pulse rate increased signifi-cantly. Induction time and recovery time were delayed significantly in group II than group I. In group II, frequency of the thrombophlebitis was lower and antegrade amnesia was greater than group I. Retrograde amnesia did not occured in both groups. On the basis of these data, midazolam used for induction maintains hemodynamic stability, induces anesthesia smoothly, produces low frequency of the thrombophlebitis and high frequency of antegrade amnesia. Therefore it is concluded that midazolam is safe and effective induction agent and may offers an advantage over thiopental in situations where hemodynamic stability is crucial.

MRI has proved to be very reliable in evaluating the menisci and cruciate ligaments. On MRI, several diagnostic criteria of ruptured ACL were reported. Boeree and Ackyroyd reported that when the ACL is ruptured the PCL may appear to be curled up or sigmoid. But these morphologic changes may be shown in the normal ACL, so the quantitative analysis of these morphologic changes in considered as a way to increase the diagnostic sensitivity. We have used 1.0 tesla MRI scanner(SIMENS W. Germany) with a surface coil. We compared two groups of patients; a ruptured ACL group(16 patients) in which had indicated and arthroscopy confirmed rupture of the ACL and control group(46 patients), in which had shown the ACL to be entirely normal. At first, we made a line(basal line) between the femoral attachment and tibial attachment of the PCL and decided the point(apex) which was located far distant from the line. And we made a line(A line) between the femoral attachment and apex of the PCL, another line(B line) between the tibial attachment and apex of the PCL. We divided the basal line into the four areas. We measured the each angle between basal line and A line(angle a), between basal line and B line(angle b). And we measured the entire length of basal line, each height of the PCL previously divided point of the basal line(H1, H2, H3) and the apex of the PCL on the basal line. We compared the control group and ruptured ACL group by t-test from the measured factors angle a, angle b, H1, H2, H3, H4, and length of basal line. We studied factors which were able to decide whether the ACL was ruptured or not in MRI finding by logistic regression. 1. H1, the distance from the basal line to the PCL at 1/4 point on the basal line, were 5.7±1.6 mm in ruptured ACL group, 4.7±1.3 mm in control group, so there was statistically significant increase in ruptured ACL group. 2. The angle a were 56.0±14.4° in ruptured ACL group, 39.7±10.1° in control group, so there was statistically significant increase in ruptured ACL group. 3. From the measured factors angle a was able to decide whether the ACL was ruptured or not in MRI and the slope of angle a in logistic regression was 0.1. In conclusion, when the apex of the PCL is located at proximal 1/4 of the PCL and PCL and greater curve, above signs will be considered to be a sign of ruptured ACL in MRI.

8.Gastrointestinal Fellowship Education in Korea.
The Korean Journal of Gastroenterology 2019;73(1):7-9
Since the residency training program in internal medicine changed from a four-year to a three-year program in 2017 in Korea, issues of an optimal training program for the gastrointestinal (GI) fellowship has arisen. Currently, the evaluation criteria for a GI fellowship in Korea include the following; 1) the total number of assigned patients during the training period, 2) the number of GI endoscopy procedures, 3) attendance at academic conferences, and 4) research presentations. However, competency-based training should be introduced in the GI fellowship training program. The current issues of GI fellowship training in Korea include the following; 1) reorganization of the GI fellowship education system and consideration of an optimal training period following the introduction of the three-year internal medicine residency training program, 2) development of a standardized, competency-based GI fellowship training program, 3) provision of a support program for instructors in GI fellowship education, 4) introduction of a mentor-mentee system, 5) introduction of an accreditation system for GI fellowship, 6) supplementation of a GI sub-specialty qualification system, and 7) provision of benefits to GI sub-specialists.

PURPOSE: To evaluate the clinical characteristics of intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures and assess the surgical outcomes of a novel, closed intramedullary nailing surgical approach designed to minimize fixation failure. MATERIALS AND METHODS: Between May 2013 and April 2017, 31 patients with intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures treated with closed intramedullary nailing or long proximal femoral nail antirotation (PFNA) were enrolled in this study. Preoperative data included age, sex, injury severity score, body mass index, location of shaft fracture, injury mechanism, accompanying traumatic injury, walking ability before injury, and surgical timing. Perioperative outcomes, including follow-up period, types of intramedullary nails, number of blocking screws used, operation time, and blood loss were assessed. Radiologic outcomes, including union rate, time from surgery to union, and femoral shortening, and clinical outcomes, including hip flexion, walking ability, and Harris hip score were also evaluated. RESULTS: A total of 29 unions (93.5%) were achieved. The time to union was 16.8 months (range, 11–25 months) for hip fractures (15.7 weeks for intertrochanteric fractures and 21.7 weeks for subtrochanteric fractures) and 22.8 months for femoral shaft fractures. There were no significant differences in surgical outcomes between the two groups except for type of intramedullary nail. CONCLUSION: Closed intramedullary nailing in the treatment of intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures may be a good surgical option. However, fixation of femoral shaft fractures might not be sufficient depending on the implant design.

BACKGROUND: Catheter-related bloodstream infections (CR-BSIs) are common, costly, and potentially lethal. The purpose of this study was to ascertain the effect of maximal sterile barrier on CR-BSIs in intensive care units. METHODS: We monitored CR-BSIs in intensive care units of Sunlin Hospital in Pohang, before (September 2005 to May 2006) and after (June to December 2006) implementation of maximal sterile barrier. CR-BSIs were identified by using the definition of Centers for Disease Control and Prevention. RESULTS: During the intervention period, the proportion of conducting maximal sterile barrier was 84%. In the pre-intervention period, 10 episodes of CR-BSIs were recorded out of a total of 1,749 catheter-days, compared to 1 episode of CR-BSI out of a total of 1,277 catheter-days in the post-intervention period. The rate of CR-BSIs was significantly reduced from 5.72 to 0.57 per 1,000 catheter-days (P=0.03). CONCLUSION: Implementation of maximal sterile barrier resulted in a significant reduction in CR-BSIs.
