Purpose: This study was conducted to gather descriptive data on trauma victims and to observe the general demographic characteristics and clinical profile of trauma victims who were admitted to a regional emergency medical center in the west southern Kyungsangnam-do area. Objects & Method: The study population consisted of 1,909 trauma patients who visited the emergency department of Gyeongsang National University Hospital between January 2003 and December 2004. The medical records were reviewed in a retrospective manner. Demographic data, the mechanism of injury, and clinical information were collected by three professional medical affairs recorders and an emergency physician and a Revised Trauma Score (RTS) and an Injury Severity Score (ISS) were calculated for each patient. Collected data were analyzed with SPSS software version 12.0. Results: Male patients outmembered female patients (M:F=2.54:1), and the mean age of the population was $40.5{\pm}21.4$ years. The mean RTS and ISS were $7.45{\pm}1.11$ and $8.40{\pm}7.44$, respectively. The seventies showed the highest ISS($10.94{\pm}8.66$). The most common mechanism of injury was motor-vehicle accidents (45.57%), followed by falls or slips(28.26%), and other blunt injuries(12.68%). The most frequent causes of death was cerebral herniation due to head injury(68.4%) and irreversible shock(26.3%). Conclusion: The present study clarified the demographic and clinical characteristics of trauma patients in the Kyungsangnam-do area. In the future, prospective clinical data collection is needed for a more sophisticated trauma study.

Purpose: This study analyzed the characteristics of unstable pelvic bone fractures associated with intra-abdominal solid organ injury. Methods: Medical records were retrospectively collected from January 2000 to December 2010 for patients with unstable pelvic bone fractures. Unstable pelvic bone fracture was defined as lateral compression types II and III, antero-posterior compression types II and III, vertical shear and combined type by young classification. Subjects were divided into two groups, with (injured group) and without (non-injured group) intra-abdominal solid organ injury, to evaluate whether the characteristics of the fractured depended on the presence of associated solid organ injury. Data included demographics, mechanism of injury, initial hemodynamic status, laboratory results, revised trauma score (RTS), abbreviated injury scale (AIS), injury severity score (ISS), amount of transfusion, admission to the intensive care unit (ICU), and mortality. Results: The subjects were 217 patients with a mean age of 44 years and included 134 male patients(61.8%). The injured group included 38 patients(16.9%). Traffic accidents were the most common mechanism of injury, and lateral compression was the most common type of fracture in all groups. The initial blood pressure was lower in the injured group, and the ISS was greater. The arterial pH was lower in the injured group, and shock within 24 hours after arrival at the emergency department was more frequent in the injured group. The amount of the transfused packed red blood cells within 24 hours was higher in the injured group than the non-injured group. Invasive treatment, including surgery and angiographic embolization, was more common in the injured group, and the stay in the ICU was longer in the injured group. Conclusion: A need exists to decide on a diagnostic and therapeutic plan regarding the possibility of intra-abdominal solid organ injury for hemodynamically unstable patients with unstable pelvic bone fractures and multiple associated injuries.

Purpose: This study analyzed the characteristics of stable pelvic bone fractures with intra-abdominal solid organ injury. Methods: Medical records were retrospectively reviewed from January 2000 to December 2009 of patients with stable pelvic bone fractures. A stable pelvic bone fracture according to Young's classification is defined as a lateral compression type I and antero-posterior compression type I. Subjects were divided into two groups, one with (injured group) and one without (non-injured group) intra-abdominal solid organ injury, to evaluate the dependences of the characteristics on the presence of an intra-abdominal solid organ injury. Data including demographics, mechanism of injury, initial hemodynamic status, laboratory results, Revised Trauma Score (RTS), Abbreviated Injury Scale (AIS), Injury Severity Score (ISS), amount of transfusion, admission to intensive care unit (ICU), and mortality were analyzed. Results: The subjects were 128 patients with a mean age of 42 years old, of whom were 67 male patients (52.3%). The injured group had 21 patients(16.4%), and the most frequent injured solid organ was the liver. Traffic accident was the most common mechanism of injury and lateral compression was the most common type of fracture in all groups. Initial systolic blood pressure was lower in the injured group, and the ISS was greater in the injured group. Arterial pH was lower in the injured group, and shock within 24 hours after arrival at the emergency department was more frequent in the injured group. Transfused packed red blood cells within 24 hours were 8 patients(38.1%) in the injured group and 11 patients(10.3%) in the non-injured group. Conservative treatment was the most common therapeutic modality in all groups. Stay in the ICU was longer in the injured group, and three mortalities occurred. Conclusion: There is a need to decide on a diagnostic and therapeutic plan regarding the possibility of intra-abdominal solid organ injury for hemodynamically unstable patients with stable pelvic bone fractures and for patients with stable pelvic bone fractures along with multiple associated injuries.

This study analyzed contributing factors affecting leg injury severity in pedestrian-vehicle crashes. A Binary Logistic Regression (BLR) method was used to identify the factors. Independent variables include characteristics for pedestrian, vehicle, road, and environmental conditions. The leg injury severity is classified into two classes, which are dependent variables in this study, such as 'severe' and 'minor' injuries. Pedestrian age, collision speed, and the height of vehicle were identified as significant factors for the leg injury. The probabilistic outcome of predicting leg injury severity can be effectively used in not only deriving pedestrian-related safety policies but also developing advanced vehicular technologies for pedestrian protection.

중추신경계는 일단 손상이 되면 손상된 세포의 재생, 손상된 수초의 회복, 신경계의 정상적인 연결 등의 제한성 때문에 그 회복이 매우 힘들다. 이러한 중추신경계의 중요한 손상으로는 다발성 경화증, 뇌졸중, 척수손상, 외상, 축삭의 탈수초화 등이 있다. 이전 연구들은 많은 발생빈도를 보이고 있는 척수손상에서 실질적인 척수의 기능적인 회복을 위해 손상된 척수신경의 재생과 축삭의 재수초화가 중요한 요인이라고 전하고 있다. 최근에는 이러한 척수손상에 대한 치료적 접근으로서 세포이식 기술이 하나의 해결책을 열어주고 있다. 따라서 본 논문에서는 척수손상의 특성을 살펴보고, 척수손상에 의한 기능장애에 대해 세포이식이 기능의 회복을 증진시킬 수 있다는 증거를 논의하고자 한다.

Purpose: The aim of this study was to identify clinical outcome and characteristics of trauma patients via emergency medical services (EMS). Methods: Medical records of the trauma patients visiting the emergency department were retrospectively collected and analyzed from January 2015 to June 2016 in the single institution. Of 529 registered patients, 371 patients were transported by - were enrolled. The parameters including age, gender, injury mechanism, Glasgow coma scale on arrival, presence of shock (systemic blood pressure <90 mmHg) on arrival, time to arrival from accident to emergency room (ER), need for emergency procedures such as operation or angioembolization, need for intensive care unit (ICU) admission, injury severity score (ISS), the trauma and injury severity score, revised trauma score (RTS), length of stay, and mortality rate were collected. The SAS version 9.4 (SAS Institute, Cary, NC, USA) was used for the data analysis. Results: Arrival time from the field to the ER was significantly shorter in EMS group. However, overall outcomes including mortalities, length of stay in the ICU and hospital were same between both groups. Age, ISS, RTS, and injury mechanisms were significantly different in both groups. ISS, RTS, and age showed significant influence on mortality statistically (p<0.05). Conclusions: The time to arrival of EMS was fast but had no effect on length of hospital stay, mortality rate. Further research that incorporates pre-hospital factors influence clinical outcomes should be conducted to evaluate the effectiveness of such a system in trauma care of Korea.

This study aims to the influenced factor analysis of spinal cord independence measure(SCIM), on walking velocity, walking endurance, time up & go(TUG), and subject characteristics. The subject of this study were 12 persons with incomplete spinal cord injury(ASIA C, D). All subject ambulatory with or without an assistive device. All participants were assessed on SCIM(score), walking velocity(m/s), walking endurance(m) and TUG(s). The data were analyzed using independent t-test and stepwise multiple regression. The results revealed that no statistical difference was noted in subject characteristics among SCIM, walking velocity, walking endurance, TUG(p>0.5). The independence score, breathing-sphincter control and ambulation were important factors in TUG(31.4%). The results suggest that SCIM may be an inappropriate assessment tool to predict gait ability of patient with incomplete spinal cord injury. Further study about gait speed, gait endurance and TUG by change of SCIM is needed using to patient of incomplete spinal cord injury.
