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.
This study aimed to understand the differences in general characteristics, principal diagnosis, injury-related characteristics, and types of transportation accidents between young-old and old-old patients who were hospitalized owing to injury based on data from the Korean National Hospital Discharge In-Depth Injury Surveys. We used a complex sample cross tabulation analysis (chi-square test) and complex sample generalized linear model (t-test). Therefore, the primary focus of healthcare professionals working with the old-old should prevent falls in the home and increase the available medical care, financial aid plans, and psychosocial support for aging. Additionally education on traffic accident prevention and road safety is particularly important for old-old patients.
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.
Acute spinal cord injury can produce neurologic injury with many physical, psychological and social ramifications. It has been shown that two separate components combine to produce neurologic damage in acute spinal cord injury : the primary and secondary injuries. The primary mediators of spinal cord injury include the actual mechanical tissue disruption which is a passive process that occurs immediately following the trauma. A secondary injury cascade follows which appears mediated by cellular and molecular processes working through complex mechanisms. Both the primary and secondary injury cascades produce cell death both in neuronal and supporting cell tissues. Recovery from central nervous system(CNS) disorders is hindered by the limited ability of the vertebrate CNS to regenerate injured cells, replace damaged myelin sheath, and re-establish functional neuronal connections. Of many CNS disorders including multiple sclerosis, stroke, and other trauma, spinal cord injury is one of the important diseases because of the direct association with the functional loss of the body. Previous studies suggest that substantial recovery of function might be achieved through regeneration of lost neuronal cells and remyelination of intact axon in spinal cord injury which is occurred frequently. As a therapeutic approach in spinal cord injury, recently, cell transplantation provides a potential solution for the treatment of spinal cord injury. This review describes the characteristics of spinal cord injury and presents some evidence supporting functional recovery after cell transplantation following spinal cord injury.
The purpose of this survey was to investigate the exercise injuries and its care methods of members in amateur tennis clubs. 176 questionnaires were surveyed from tennis players who were exercising at 6 tennis club ranges in J city, Korea. The interesting variables were parts, time slots, causes, treatments of injuries, which were analyzed based on the general and exercise characteristics of surveyees, a gender, an age, an exercise career, an exercise time, an occupation, an average earning. The results of this study were as follows: 1) In the results of analyses for the injury parts, the upper bodies injuries were more than lower body ones, the injury of back and lumbus had the highest rate among upper body injuries. In twenties, the number of injury had highest rate. 2) The main cause of injury was the carelessness of one's own. The most injury by the carelessness of one's own was a reason for a lack of warm-up. 3) The first emergency manager for the injury was mostly oneself.
The past five years, industrial accidents due to food processing machinery have been occurred 725 cases, injury by the food cutter occurred 390 cases in its. On this study, to prevent food cutter injury, an attempt is made to present the improved documentation of fundamental safety of the food cutter workplace through the injury analysis of food cutter injury and surveys on band saw machine business field. Analyzing the result of 390 cases on food cutter injury, amputation, cut, puncture occupied 75.1 percent (293 cases), compressed occupied 23.3% (91 cases), also it showed constant component without reference to gender, age, scale of work place, service period. In the survey, lack of concentration for workers have been pointed out as the biggest factor in the cause of band saw machine injury. Meanwhile, such as the EU and Japan, whereas presents safety standards about band saw machines that are tailored to each country, on the other hand, South Korea doesn't provide the standards. To prevent the food cutter injury, safety standards need to be established in consideration of amputation, cut, puncture, compressed injury and financial support is required to procure protective equipment at each place of business.
