Vertebral artery (VA) injuries usually accompany cervical trauma. Although these injuries are commonly asymptomatic, some result in vertebrobasilar infarction. The symptoms of VA occlusion have been reported to usually manifest within 24 hours after trauma. The symptoms of bilateral VA occlusions seem to be more severe and seem to occur with shorter latencies than those of unilateral occlusions. A 48-year-old man had a C3-4 fracture-dislocation with spinal cord compression that resulted from a traffic accident. After surgery, his initial quadriparesis gradually improved. However, he complained of sudden headache and dizziness on the 5th postoperative day. His motor weakness was abruptly aggravated. Radiologic evaluation revealed an infarction in the occipital lobe and cerebellum. Cerebral angiography revealed complete bilateral VA occlusion. We administered anticoagulation therapy. After 6 months, his weakness had only partially improved. This case demonstrates that delayed infarction due to bilateral VA occlusion can occur at latencies as long as 5 days. Thus, we recommend that patients with cervical traumas that may be accompanied by bilateral VA occlusion should be closely observed for longer than 5 days.

This study was initiated to minimize head injuries, which is the largest cause of increased external activity, traffic accident injuries, and death. We developed a low cost airbag that can be covered by a safety helmet based on consumer needs. The results of the survey showed that safety is the most important aspect of consumers' safety helmets. It also predicted that increasing the weight would present the biggest problem. Curved airbag cushion parts that can be attached to a helmet and the sensor part of a block type were designed. Impact analysis was performed by specifying the pressure inside the airbag and the volume of the airbag as variables.

Objectives: This study was conducted to examine the association between health condition and leaving the labor market among middle-aged and older adults in South Korea. Methods: Data was obtained from individuals aged 45 years and older participating in the 2006 and 2008 Korean Longitudinal Study of Ageing. We used various health measures including chronic diseases, comorbidities, traffic accident injuries, disabilit of instrumental activities of daily living, depressive symptoms, and self-rated health. The odds ratios of job loss, and retirement, versus employment were calculated using multinomial logistic regression by each health measure. Results: In our cross-sectional and longitudinal analysis, health problems related to physical disabilities had the greatest effect on leaving the worksite. A shift in health condition from good to poor in a short period was a predictor of increased risk of unemployment but a persistent pattern of health problems was not associated with unemployment. Women with health problems showed a high probability of retirement, whereas among men, health problems instantly the possibility of both job loss and retirement. Conclusions: Health problems of middle aged and older workers were crucial risk factors for retirement and involuntarily job loss. Especially functional defect and recent health problems strongly and instanty affected employment status.

Purpose: Traumatic diaphragmatic injury (TDI) is no longer considered to be a rare condition in Korea. This study investigated differences in the prevalence of accompanying injuries and the prognosis in patients with traumatic diaphragmatic damage according to the mechanism of injury. Methods: We retrospectively reviewed the medical records of patients with TDI who were seen at a regional emergency medical center from January 2000 to December 2018. Among severe trauma patients with traumatic diaphragmatic damage, adults older than 18 years of age with a known mechanism of injury were included in this study. Surgery performed within 6 hours after the injury was sustained was defined as emergency surgery. We assessed the survival rate and likelihood of respiratory compromise according to the mechanism of injury. Results: In total, 103 patients were analyzed. The patients were categorized according to whether they had experienced a penetrating injury or a blunt injury. Thirty-five patients had sustained a penetrating injury, and traffic accidents were the most common cause of blunt injuries. The location of the injury did not show a statistically significant difference between these groups. Severity of TDI was more common in the blunt injury group than in the penetrating injury group, and was also more likely in patients with respiratory compromise. However, sex, the extent of damage, and the initial Glasgow coma scale score had no significant relationship with severity. Conclusions: Based on the findings of this study, TDI should be recognized and managed proactively in patients with blunt injury and/or respiratory compromise. Early recognition and implementation of an appropriate management strategy would improve patients' prognosis. Multi-center, prospective studies are needed in the future.

Purpose: Crushing injuries by car tires result from a combination of friction, shearing, and compression forces and the severity of injury is influenced by the acceleration. Because car-tire injuries of the lower leg in children are common these days but they have received little attention; thus, our purpose was to look closely into this problem. Methods: A retrospective analysis was conducted of data from children under 15 years old age who visited an emergency department because of a car-tire-related crushing injury to the lower leg in pedestrian traffic accident from January 2008 to September 2012. The patient's age, sex, site of injury, degree of injury, associated injuries, type of surgery, and complications were reviewed. Results: There were 39 children, the mean age was 8.0 years, and 71.8% were boys. The dorsal part of the leg was involved most frequently. According to the severity classification, 15 children were grade I, 6 were grade II, and 18 were grade III. Among 24 patients, 13 were treated with skin graft and 3 were treated using a sural flap. Twelve patients developed complications, such as hypertrophic scarring, contractures, and deformities with significant bone loss. Conclusion: Various degrees of skin or soft tissue defects were caused in children by car tires. In this study, patients were often also had tendon or bone damage. Proper and timely initial treatments are needed to reduce the incidence of infection, the number of operative procedures, and the hospital stay.

Childhood injuries are the primary cause of death and disability among children aged 5 to 14. Consistent practice of learned safety behaviors can reduce the occurrence of severe injuries among children. However, safety behavior concern is low among Korean-American children specifically and American children, in general. The objective of the study is to evaluate the impact of an unintentional injury prevention curriculum, Risk Watch among Korean-American children. A quasi-experimental design with a nonequivalent control group was used for the designed of the study. Two intervention and two control Korean schools in Atlanta participated in this study. The intervention consisted of weekly lessons in traffic, bicycle, pedestrian, and fire safety. One hundred and two students completed a pre-test and a post-test. The main outcomes were safety behaviors (seat belt use or helmet use), behavioral intentions, and safety knowledge. Analysis of covariance was used for the statistical analyses. Strong intervention effects were found for increasing knowledge of all safety topics in the intervention group. Additionally, statistically significant intervention effects were detected for increasing seat belt and helmet use, as well as behavioral intentions of wearing a seat belt and wearing a helmet, among pre-kindergarten and kindergarten students. For students in grades 1 and 2, intervention effects were found for increasing helmet use. Among students in grades 3 to 8, the intervention group showed statistically significant increases for seat belt use. Limitations of the study and recommendations for modifying and supporting unintentional injury prevention programs for school children are discussed.

둔상에 의한 쇄골하 동맥 가성동맥류의 발생은 드물며, 관통상 이후에 이차적으로 발생하는 경우가 있다. 대게 쇄골하 동맥은 주변의 인대, 근막뿐만 아니라 쇄골, 첫 번째 갈비뼈, 심부 경부 조직들에 의해 보호받고 있어 둔상으로 의한 합병증으로 쇄골하 동맥의 손상이 발생하는 경우는 드물다. 쇄골하 동맥의 손상은 외상 초기에 나타나며, 동맥 파열은 생명을 위협할 수 있는 출혈, 가성동맥류 형성, 상완신경총 압박 등을 유발할 수 있다. 쇄골하 동맥 손상은 쇄골골절, 총상, 관통상이나 중심정맥삽관 같은 술기의 합병증으로 발생하는 것이 대부분이다. 쇄골 주변의 큰 혈종이나 맥박이 느껴지는 종괴가 있다면 심각한 혈관 손상 가능성이 높아지므로 이러한 소견이 있는지 이학적 검사를 통해 확인해야만 한다. 1993년에 외상성 혈관손상의 치료에 있어 혈관 내 스텐트 삽입 시술이 처음 발표된 이후 혈관내 스텐트 삽입 시술을 통해 외상성 혈관 손상을 치료하는 사례가 점차적으로 많아지고 있다. 이 연구는 교통사고 10일 후에 발생한 쇄골하 동맥 가성동맥류 환자에서 혈관내 스텐트 삽입을 통한 성공적 치료와 관련된 임상양상과 추정되는 병태생리에 대해 보고한 사례연구이다.
