Bisphosphonate is used widely for osteoporosis management. On the other hand, some studies have reported that prolonged use of bisphosphonate without a proper resting period can cause insufficiency fracture and, in rare cases, fractures on the femur neck. This paper reports a case of an elderly patient who suffered bilateral femur neck insufficiency fractures induced by non-stopped long-term bisphosphonate therapy. The patient complained of pain in her buttocks at the first visit. During the admission period, inguinal area pain newly developed. Both a femur neck insufficiency fracture was observed on the hip radiographic image. Hip pinning and postoperative parathyroid hormone treatment were performed. The patient was discharged without specific complications and reported improvement in symptoms on the last follow-up. Several authors have reported one-sided femoral neck insufficiency fractures due to bisphosphonate use, but the present case is uncommon in that it occurred simultaneously in both femur necks. In addition, in the case of bilateral femur fractures, the walking ability after surgery is lower than that of one-sided fracture cases, so active rehabilitation is necessary.

The incidence of ectpic pregnancy has increased rapidly over the past decade. Currently, the complications of this disorder make it one of the leading causes of maternal mortality and morbidity. In the late 1980s, reports of successful use of methotrexate (MTX) as a non surgical treatment for ectopic pregnancy (EP) also began to appear in the literature. With MTX emerging as a possible alternative management of selected women with an EP, an analysis of its comparative costs is now needed. We examined retrospectively the costs associated with management of EP in our hospital. We selected 30 women with EPand divided them into two groups of MTX treated group (n= l0) and surgically treated group (n=20). There were no statistically significant differences in the doctors fee, room, charge and cost of laboratory and radiologic examination between two groups. But We found significant reduction in cost with regard to pharmacy, injection, procedure and operation of MTX treated group compared to surgically treated group (p<0.05). Consequently the use of MTX for EP should still be considered investigational; we recognize and agree that the evolution of this remedial option should be based primarily on its ability to decrease morbidity and mortality rather than on its ability to reduce costs. If medical treatment proves to be effective, the potential cost savings demonstrated in this report will become an important influential factor on selecting alternative remedy.

OBJECTIVE: To assess the reliability of triple marker screening test in midtrimester pregnancy for fetal Down syndrome. METHODS: From October 1, 1996 to May 31, 1998 at Nowon Eulji Hospital, 3700 Pregnant women underwent serum tiple marker screening for Down syndrome during 15-20weeks of gestational age. The results of serum triple marker screenig tests for Down syndrome and the outcomes of pregnancies were retrospectively assesed. RESULTS: Sixty seven of 3700 cases(1.81%) were positive in screening test, and 3633(98.18%) cases were negative. Among 67 cases of positive screening test, 1 case(1.49%) was diagnosed as Down syndrome. Among 3633 cases of negative screening test, 4 cases(0.1%) were diagnosed as chromosomal abnormalies postnatally. Two of these 4 cases of chromosomal abnormalies were Down syndrome. CONCLUSION: With this results, sensitivity of triple marker screeing test for Down syndrome is very low as 33.3%. In order to increase the sensitivity, some compensatory adjustment is required in triple marker screening test.

In order to find out the distribution of fibronectin and fibrinogen in placenta among pregnancy induced hypertensive (PIH) patients, 6 normotensive pregnancies and 17 PIH patients were chosen. The placentas were obtained right after delivery and soaked in the 10% formalin solution. The score was measured in terms of the positiveness of the stain in immunohistochemical stain by using I antibody with the rabbit antihuman fibronectin and the rabbit anti-human fibrinogen. Comparison between two groups are as following: 1.The placenta of PIH patients showed significantly reduced positiveness of fibronectin in their fetal villous vessels and villous stroma. 2. In the PIH patients, the positiveness was reduced in the group giving the birth to intrauterine fetal growth retardation compared to giving birth to normal baby. 3. In both normotensive and PIH patients, the villous basement membrane did not show the staining response to fibronectin, while showing heavy staining response to fibrinogen. 4. The positiveness of fibrinogen in fetal vessels, villous basement membrane, intervillous space and stroma were almost same in both normotensive and PIH patients. From above results, we can conclude that there is abnormality in the distribution of fibronectin especially in the fetal vessels and the villous stroma of placenta among PIH patients. The cause of this result needs further study.

OBJECTIVE: To evaluate the epidemiologic change of patients with spinal cord injury who were admitted to a Rehabilitation Hospital, Yonsei University College of Medicine, during 1987-1996 and 2004-2008. METHODS: Medical records of 629 patients with spinal cord injury admitted to the Rehabilitation Hospital, Yonsei University College of Medicine, from 2004 to 2008 were collected and reviewed retrospectively. RESULTS: The male-to-female ratio decreased to 2.86:1, the mean age at injury increased, nontraumatic etiology increased, traffic accident remained to be the most common in traumatic spinal cord injury, and falling increased significantly. Tumor was the most common etiology in nontraumatic spinal cord injury, tetraplegia and incomplete injuries occurred more than paraplegia and complete injuries, indwelling catheter was the most common voiding method, and the duration of hospitalization decreased. CONCLUSION: Many trends changed in epidemiology of spinal cord injury.

A Computer-Based Examination(CBE) System is developed to take the effective examination for medical student. The server system is operated with Windows NT(Korean ver. 4.0) and the clients system with Windows 95(later than ver. OSR 2), and the Microsoft SQL server(ver. 7.0) is used for database server, and the Inprise Delphi(ver. 4.02) for development tool. This system consists of five subsystems(item bank, item selection, implementation, item analysis). The CBE system is designed to execute the multimedia data(image, sound, movie), and for professors to build question items, to extract the items for examinations on this system, and for students to conduct the examination on the client computer systems. It will reduce time to mark examination papers and to analyze the items, and can be applied for self-studying(computer assisted learning, CAL) with linking to internet or knowledge-base system.

BACKGROUND: We evaluated the optimal concentrations of eye opening and orientation after propofol- fentanyl TCI by CSDT of the pharmacokinetic model using DiprifusorTM in adults retrospectively. Furthermore, we tried to compare those data with the cases of using propofol TCI alone that had been reported. METHODS: After obtaining informed consent and IRB approval, 124 patients of ASA class I or II scheduled for elective surgery were allocated into 3 groups according to age. Three groups were group 1 (n = 40): 18 - 29 years, group 2 (n = 42): 30 - 39 years, group 3 (n = 42): 40 - 54 years. Propofol infusion was started at a propofol target concentration (CT) of 6 microgram/ml by using DiprifusorTM. Anesthesia was mostly maintained with propofol CT 3.5 microgram/ml and fentanyl CT 1.5 ng/ml using a Stelpump and 67% nitrous oxide in oxygen. We estimated the average concentrations of propofol at eye opening and orientation in each group with DiprifusorTM, and we also evaluated the correlation coefficient. RESULTS: Total requirements of propofol in cases of propofol-fentanyl TCI were decreased by 18-26% than in propofol TCI alone. The average concentrations of propofol at eye opening and orientation after surgery were 1.2 - 1.4 microgram/ml. The times to show eye opening and orientation after surgery from stopping of nitrous oxide and infusion were 10.4 - 14.5 min in the propofol-fentanyl group compared with 7.5 - 11 min using propofol TCI alone. CONCLUSIONS: We concluded that the optimal concentrations of propofol at eye opening and orientation after surgery in cases of combination with fentanyl were 1.2 - 1.4 microgram/ml instead of 1.4 - 1.6 microgram/ml with using propofol alone.

A primary mucosa-associated lymphoid tissue lymphoma (MALT lymphoma) of the breast is extremely rare. We report a case of a MALT lymphoma of the breast that presented as a palpable left breast mass in a 37-year-old woman. A physical examination revealed a large firm, and fixed mass in the left inner breast. Mammograms showed a large, isodense mass in the lower inner quadrant of the left breast and an enlarged lymph node in the axilla. A sonogram demonstrated a 5 cm sized, oval, circumscribed, and heterogeneously hypoechoic mass with posterior acoustic enhancement. A surgical biopsy was performed, and the pathology revealed a MALT lymphoma.
