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.

We analyzed alcoholic extracts of herbs possessing anti-neosporal activity against Neospora (N.) caninum. To identify the chemical components of Sophora (S.) flavescens and Torilis (T.) japonica associated with anti-neosporal activity, specific fractions were isolated by high-performance liquid chromatography (HPLC). In vitro activity of the fractions against N. caninum was then assessed. Gas chromatography/mass spectrometry (GC/MS) was used to identify and quantify specific anti-neosporal molecules in the herbal extracts. Almost all HPLC fractions of S. flavescens and T. japonica had higher levels of anti-neosporal activity compared to the not treated control. Active constituents of the extracts were sophoridane, furosardonin A, and tetraisopropylidene-cyclobutane in S. flavescens; 5,17-beta-dihydroxy-de-A-estra-5,7,9,14-tetraene, furanodiene, and 9,12-octadecadienoic acid (Z,Z)-(CAS,1) in T. japonica.

BACKGROUND: In a noisy hospital setting, it is not easy to induce hypnosis or sedation calmly. Although the noise stress has been neglected, it seems to disturb a patient's sleep or induction of sedation. Therefore, we tried to evaluate the effects of loud operating room (OR) background noise on bispectral index (BIS) during monitored anesthesia care (MAC) by using an audiometer and BIS monitor. METHODS: Thirty adult patients (ASA class I) were scheduled two times for nasal or dental procedures at an interval of two or three days. In a randomized, cross-over study design, we prospectively compared the BIS values according to the loudness of OR noise in two different depths of sedation during MAC. Propofol target controlled infusion (TCI) was started at a propofol target concentration (CT) 2.0 microgram/ml using a DiprifusorTM with flash mode until a BIS 80 and/or a modified Observer's Assessment of Alertness/Sedation (mOAAS) score of 4 (group 1), and BIS 75 and/or mOAAS score 3 (group 2) was obtained. We evaluated the effect site concentrations and the elapsed time and checked the BIS at 50, 80, 110, and 120 dB of sound pressure level (SPL) in both groups. RESULTS: The BIS at 80, 110 and 120 dB of SPL in group 1 was significantly increased compared to those at 50 dB (P < 0.05). Similarly, the BIS at 110 and 120 dB of SPL in group 1 was significantly increased compared to those at 80 dB (P < 0.05). The patients in their twenties were most susceptible to loud OR noise during sedation. CONCLUSIONS: The loud OR background noise might be possible to interfere with induction of sedation to a degree, which was more noticeable on light to moderate sedation than for deep sedation.

PURPOSE: A cross-calibration equation is needed to compare bone mineral density measured by different dual X-ray absoptiometry systems. We performed this study to establish appropriate cross-calibration equations between two different dual X-ray absorptiometry systems. MATERIALS AND METHODS: Bone mineral density of anterior-posterior lumbar spine (L2-4 level) and femoral neck were measured in 109 women (55+/-11yr) using two different dual X-ray absorptiometry systems (Lunar EXPERT-XL) and Hologic QDR 4500-A). Bone mineral density values measured by two systems, including area, bone mass content, bone mineral density and percentile of young normals were compared and cross-calibration equations between two systems derived. RESULTS: The bone mineral density values of 109 women measured by Lunar system were 0.958+/-0.17 g/cm2 at L2-4 and 0.768+/-0.131 g/cm2 at femur neck, which were significantly higher (13+/-6% at L2-4 and 19+/-7% at femur neck, p<0.001) than those (0.851+/-0.144 g/cm2 at L2-4 and 0.649+/-0.108 g/cm2 at femur neck) by Hologic system. Bone mineral content and percentile of young normals measured by Lunar system were also significantly higher than those by Hologic system (p<0.001), whereas there was no difference in area (p>0.05). There was a high correlation between bone mineral density values of L2-4 and femoral neck obtained with both dual X-ray absortiometry systems (r=0.96 and 0.95, respectively). Cross-calibration equations relating the bone mineral density were Lunar=1.1287xHologic-0.0027 for L2-4 and Lunar=l.1556xHologic+0.0l82 for femoral neck. CONCLUSION:: We obtained cross-calibration equations of bone mineral density between Lunar EXPERT-XL and Hologic QDR 4500-A. These equations can be useful in comparing bone mineral density obtained by different dual X-ray absorptiometry systems.

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.
