BACKGROUND: We designed this study to determine whether trauma history and initial assessment anticipate the injury severity of the free-fall patient. METHODS: Two hundred patients who admitted emergency department of Severance hospital because of the fall from a height were enrolled in this study. The height of fall, the body orientation, and the characteristics of impacted material, and the Injury Severity Score(ISS) were evaluated by retrospective chart reviews. And regression equations were determined for predicting ISS on the basis of clinical parameters using multiple regression analysis. RESULTS: According to the characteristics of impacted material, the ISS was higher in the hard surface(13.7+/-9.5) than the sort surface(10.5+/-8.8)(p<0.05). There were correlations between height of fall and ISS(p<0.01, r=0.5). To the body orientation, the ISS was higher in the head-to-feet orientation(18.211.7) than the feet-to-head(10.9+/- 7.0) or other position(8.5+/-5.8)(p<0.01). The regression equations were as follows, ISS=2 +0.082xage(year)-1.54x(Glasgow Coma Scale)-3x(feet-to-head orientation)+0.65x height of fall(m)+2.7 x (hand surface)(p<0.01, R2=0.53). CONCLUSION: This study suggest that the injury severity of patient with free fall are significancy related to the height of fall, the characteristics of impacted material and the body orientation.

Lobectomy with mediastinal node dissection has been standard treatment for non-small cell lung cancer (NSCLC). Nowadays, video-assisted thoracoscopic surgery (VATS) is gaining acceptance as an alternative treatment option, given the quality-of-life benefits that it confers. For the VATS procedure, most surgeons create two or three ports with a utility incision of 3 to 5 cm. However, with acquired skill and instrumentation advances, single-incision thoracoscopic surgery has emerged over time. Here, we report the case of an 86-year-old female with NSCLC treated by single-incision segmentectomy.

Although many prosthetic materials exist for fabrication of implant-supported telescopic overdentures, available materials have not been thoroughly evaluated from a functional standpoint. This case report describes the use of polyaryletherketone (PAEK) based polymer for an implant-supported telescopic overdenture, a seldom used material in dentistry. This material is lighter than traditional materials, can accommodate changes in retentive forces, and is an easily retrievable by CAD/CAM fabrication. This case highlights the possibility of using new polymer materials for implant-supported telescopic overdentures.

PURPOSE: We analyzed the cases of supracondylar-intercondylar femoral fracture treated with retrograde intramedullary nail and report the clinical results and its usefulness. MATERIALS AND METHODS: We reviewed 17 cases of supracondylar-intercondylar femoral fracture that had been treated with retrograde intramedullary nail and each of patients had been followed up for a minimum one year. Post-operative functional assessment was performed using a scale developed by Sanders et al. The evaluation scale assesses range of motion, pain, walking ability, return to work, and alignment and shortening as measured on radiograph. RESULTS: According to functional assessment of Sanders et al, there were 6 excellent, 9 good, 1 fair, and 1 poor results, that is, 94% showed above excellent results. Bony union was obtained in average 5 months after operation. The post-operative complications were varus deformity in 1 case, wound infection in 1 case, stiffness of knee joint in 1 case, and metal failure in 1 case. CONCLUSION: The treatment of supracondylar-intercondylar femoral fracture with retrograde intramedullary nail is one of the good surgical options for clinically preferable results with the advantages in early joint motion and early ambulation.

OBJECTIVE: This study was designed to evaluate the effect of epidural analgesia on the course of labor and delivery mode. METHOD: Three hundred eighteen term pregnant women with singleton fetus in vertex presentation were admitted for vaginal delivery at the Department of Obstetrics and Gynecology, medical center Chung-ju hospital from January 1, 1998 to December 31, 1998. They were divided into two groups: epidural analgesia group and non-epidural analgesia group. Epidural analgesia group was 106 women (79 primiparas and 27 multiparas). Non-epidural analgesia group was 212 women (138 primiparas and 74 multiparas). Course of labor and delivery mode were compared between the two groups. RESULTS: 1. The duration of the first stage of labor was not significantly different between two groups (primiparas: 672+/-110 min vs 625+/-134 min, multiparas: 458+/-152 min vs 422+/-184 min), and that of the second stage of labor in the primiparas was significantly longer in epidural analgesia group than non-epidural analgesia group (62+/-25 min vs 42+/-20 min, p=0.03), but did not differ significantly in the multiparas groups (36+/-12 min vs 31+/-20 min).2. Cesarean delivery rates were not significantly different between two groups (19.8% vs 15.1%).3. Cesarean delivery rates due to failure to progress were not significantly different between two groups (85.7% vs 78.1%).4. Oxytocin augmentation rates were significantly higher in epidural analgesia group than in non-epidural analgesia group (primiparas: 42.3% vs 20.1%, p=0.008, multiparas: 38.5% vs 19.7%, p=0.01).5. The newborn birthweight, Apgar score and the incidence of meconium-stained amnionic fluid were not significantly different between two groups.6. The complication of the epidural analgesia were back pain (10.4%), shivering (7.5%), nausea and vomiting (1.3%), hypotension (0.9%), and voiding difficulty (0.9%). CONCLUSION: Though epidural analgesia prolonged second stage of labor in the primiparas and increased oxytocin augmentation rates but did not increased the cesarean delivery rates. So intrapartum epidural analgesia provided safe and effective pain control without undesirable effects on labor outcomes.

BACKGROUND: In recent years, a combination of two demographic phenomena, an increased number of older people in the population and an increase in the incidence of lung cancer with age, has made it mandatory to develop therapeutic modalities with less toxicity for the treatment of inoperable elderly patients with lung cancer. Therefore, we investigated the correlation between COX-2 expression and cytotoxicity of Nimesulide, a specific COX-2 inhibitor. MATERIAL AND METHOD: Immunohistochemical staining of COX-2 was performed. After exposure of Nimesulide, XTT analysis, FACS analysis and Hoechst staining were carried out. RESULT: COX-2 protein was expressed in non- treated A549 cells strongly, but not in H1299. Cytotoxicity of Nimesulide against A549 cell and H1299 cell were similar and IC50 of Nimesulide in both cell lines were 70.9 microM in A549 cell line and 56.5 microM in H1299 cell line respectively. FACS analysis showed G0/G1 arrest in both cell lines and the S phase cell fraction was decreased. Morphologic assessment of apoptosis by Hoechst 33258 staining, many apoptotic cells were detected in both cell lines. CONCLUSION: Selective COX-2 inhibitor, Nimesulide, can inhibit the proliferation of non-small cell lung cancer cell lines in vitro. Inhibitory effect of Nimesulide are induction of apoptosis and G0/G1 arrest. There is no correlation between COX-2 expression and cytotoxicity of Nimesulide, a specific COX-2 inhibitor. Therefore, highly selective COX-2 inhibitors such as Nimesulide can be expected to lead to even greater efficacy of their use as adjuncts to various anticancer angents and radiation therapy for the treatment of high-risk patients.

OBJECTIVE: The aim of this study is to assess the relationships between maternal plasma and umbilical cord leptin concentrations and their effects on newborn birth weights, maternal body mass indices and fetal sex in term normotensive (NT) and preeclampsia (PE) women. METHODS: Blood samples were obtained at delivery from 20 NT group and another 20 from PE group of at least 36 weeks of gestation. And the umbilical cord samples were also taken from their newborns at birth. Plasma leptin levels were determined in both groups using a human recombinant leptin 125-I radioimmunoassay. RESULTS: Mean maternal plasma and umbilical cord leptin concentrations were 16.16+/-2.05 ng/ml and 7.11+/-1.01 ng/ml in NT group, 17.09+/-1.67 ng/ml and 8.55+/-6.63 ng/ml in PE group, and there was no statistical significances among them. The differences of leptin concentrations in maternal plasma and umbilical cord according to baby sex were not significant in both NT and PE groups. Plasma leptin concentrations were related with maternal weight gain and BMI in NT group and with body weight in PE group. The BMI and birth weights of the neonates have significant effects on the umbilical cord leptin concentrations in both NT and PE groups. CONCLUSION: In this study, no correlation was found between maternal plasma and umbilical cord leptin concentrations in both NT and PE groups. But maternal plasma leptin concentrations had positive correlations with maternal body weight, BMI, and body weight changes during pregnancy in both NT and PE groups. There were also positive correlations among umbilical cord leptin concentrations, BMI and birth weights of the neonates of NT and PE groups term. Therefore umbilical cord leptin is considered to be the index of fetal birth weight.

Papillary fibroelastoma is a rare benign tumor of the heart. A 21-year-old man presented with dyspnea on exertion and echocardiogram showed a small round mass attached to the anterolateral papillary muscle. After excision of the mass, including anterior papillary muscle, chordae tendinae, and anterior leaflet, he underwent mitral valve replacement with a mechanical valve. He was discharged on anticoagulant therapy without further problems.
