Objectives: Due to their developmental characteristics, adolescents have a higher probability than other age groups of experiencing injuries caused by accidents, violence, and intentional self-harm. The severity and characteristics of injuries vary by the intentionality and mechanism of injury; therefore, there is a need for a national-level estimate of the scale and the severity of injuries in adolescents that takes these factors into account. Methods: By using data from the Emergency Department-based Injury In-depth Surveillance Data, National Emergency Department Information System, the Korean National Hospital Discharge In-depth Injury Survey, and cause of death statistics, we calculated the emergency department (ED) visit rate, hospitalization rate, and death rate of injuries per 100 000 adolescents for each injury mechanism. The calculated rates were used to generate the injury pyramid ratio (ratio of death rate to hospitalization rate to ED visit rate) to visualize the scale and the severity of the injury. Results: The mortality rate in adolescents due to injury was 10/100 000; the corresponding rates for hospitalization and ED visits were 1623 and 4923, respectively, resulting in an injury pyramid ratio with the general pyramid form, with a 1:162:492 ratio of deaths to hospitalizations to ED visits. The mortality rate due to suicide/intentional self-harm was 5/100 000, while 35 were hospitalized for this reason and 74 made ED visits. The pyramid ratio of 1:7:15 for intentional self-harm/suicide showed a steep pyramidal form, indicating considerable lethality. The mortality rate due to motor vehicle collisions (MVCs) was 3/100 000; 586 were hospitalized for this reason, while 1023 made ED visits. The pyramid ratio of 1:195:341 for MVCs showed a gradual pyramid form, indicating that the lethality was low and the scale of injury was high. Conclusions: The main categories of injuries in adolescents were visualized in pyramid form, contributing to an understanding of the scale of each injury by mechanism in terms of levels of death, hospitalization, and ED visits. These findings will be helpful for understanding how to prioritize injuries in adolescents.

손상부담은 우리사회에서 매우 심각한 것으로 널리 인식되고 있다. 그럼에도 불구하고 손상감시에 필요한 데이터가 충분하지 않다. 이 연구의 목적은 손상감시를 위해 핵심 데이터를 선택하고 보완하는 것이다. 이를 위해 본 연구에서는 통계품질 6가지 차원에 따라 '사망원인통계', '건강보험통계', '퇴원손상조사'에 대한 품질평가보고서 등의 문헌을 분석 하였다. 분석결과는 '사망원인통계'와 '건강보험통계'가 손상감시를 위한 핵심데이터로서 유용성이 있다는 것이다. 그러나 '건강보험통계'에는 손상외인에 대한 데이터가 부족하다는 단점이 있다. 단점을 보완하기 위해, 본 연구에서는 국민건강보험 의료비 청구 시 의료기관이 손상외인을 의무적으로 신고하도록 하는 제도를 제안한다. 이 제도의 결과로서 우리는 '손상 피라미드 구축', '국민연금과의 데이터 연계', '손상 데이터의 시의성 향상'을 기대할 수 있다. 그리고 이 제도 실현을 위한 후속 연구를 기대한다.

Objective : In this study, we used the aged bilateral common carotid artery occlusion (BCAO) rats were used to measure the effect of Bupleuri Radix (Si-Ho) on the brain ischemic injury, because aging is an important factor in storke, Method : The brian ischemic injury was induced by temporary closing of carotids on both sides in a low blood pressure state. Bupleuri Radix (Si-Ho) was orally administered in 18-month-old BCAO rats. Result : The Ischemic Damaged Hippocampus and HSP expression were analyzed by the immunohistochemical staining and the result were as follows: 1. The low numbers of pyramid cells in the hippocampus CA1 area for the ischemically injured experimental group rose to numbers simillar to those of the control group. 2. The thin neuronal cell layer in the hippocampus CA1 area for the ischemically injured experimental group returned to thickness simillar to those of the control group. 3. The normalized optical density of HSP70 expression was suppressed in CA2, DG and CA1 expression was significantly suppressed in the experimental group compared to the control group. Conclusion : These results suggested that Bupleuri Radix (Si-Ho) has a neuroprotective effect by reducing neural cell injury in the initial ischemic state.

Purpose: In cases where nasal fractures involve frontal process of maxilla or perpendicular plate of ethmoid, 4 - 5 days of nasal packing may not provide sufficient support for avoiding displacement after packing removal. Therefore a single Kirschner - wire(K - wire) is used as an internal splint when nasal fractures involve the above two areas. Methods: Thirty five patients during the last 3 practical years were treated with a K -wire pinning according to the anatomic locations of nasal fractures. We performed a retrospective study using 13 nasal fractures out of total 35 patients. Among 13 cases, 10 patients involved frontal process of maxilla, and 3 patients were diagnosed as bilateral nasal side wall fractures accompanied with fractures of perpendicular plate of ethmoid. One patient of the last three cases had been augmented with dorsal silicone implant long before the trauma. We analyzed the anteroposterior displacement of key stone area and the width between both lateral walls by comparing immediate postoperative radiographs with 2 month follow - ups. To reduce the errors, the same measurements were taken by two different inspectors, and the mean of each inspector's measurements was compared. Patient satisfaction was analyzed using a questionnaire regarding the esthetic and functional outcomes. Results: Ten patients underwent a longitudinal K - wire fixation in submucoperiosteal plane underneath the frontal process of maxilla. And three patients underwent a transverse K - wire fixation from the one side of lateral wall to the perpendicular plate of ethmoid and to the other side of lateral wall. The mean postoperative anteroposterior displacement of the key stone area measured by two inspectors were 1.84% and 3.06%; mean narrowing of bony pyramid were 1.33% and 1.48%, respectively. Subjective satisfaction scores regarding the esthetic appearance and the maintenance of nasal shape compared with immediate post - operative state with the long term ones were not different (p>0.05). Conclusion: K - wire pinning after closed reduction is a reliable and useful method for the treatment of nasal fractures involving frontal process of maxilla or perpendicular plate of ethmoid. This is because it achieves longer intranasal support after reduction. This method also leaves conspicuous external scar, and minimal soft - tissue injury.
