Purpose: The 12-lead electrocardiogram has limitation for detection of lateral wall myocardial infarction (MI). Therefore, this study was conducted to compare the location of leads V5 and V6 with the left ventricle (LV) lateral wall using multidetector computed tomography (MDCT) and propose new additional leads for detection of lateral wall MI. Methods: From 120 study subjects who underwent chest MDCT, we measured the angle (θ) between the midsagittal plane and long axis of LV on the coronal imaging of MDCT. Using this, another angle (90-θ) between the long axis of LV and leads V5 and V6 was calculated. After the location of the leads V5 and V6 was identified using axial and coronal images of MDCT, the positional relationship between leads V5 and V6 and the lateral wall was compared based on the thoracic spine. Results: The θand 90-θwas 52.2 ±10.3 and 37.8 ±10.3 , respectively. Leads V5 and V6 faced the LV lateral wall very obliquely. The score of leads V5 and V6 position based on the thoracic spine was 6.9±1.8 points as the level of lower part of 9th vertebral body. Meanwhile, the lateral wall of LV was 4.7±2.2 points as the lower part of the 8th vertebral body. Thus, leads V5 and V6 were located lower by the height of one thoracic vertebral body than the lateral wall of LV on coronal images (p<0.001). Conclusion: Leads V5 and V6 are inappropriate for detection of the lateral wall MI. To diagnose that more efficiently, we propose the new additional leads, elevated V5 and elevated V6, located two or three intercostal spaces upward from leads V5 and V6.

Hemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory syndrome caused by excessive activation of lymphocytes and macrophages, leading to cytokine storm. Infection-associated HLH is most common, and Epstein-Barr virus is the leading triggers. Quick diagnosis is essential for starting the treatment before irreversible damage. We report a case of 16-year-old boy who presented with unremitted fever, jaundice, and erythematous maculopapular rash all over the body. Investigations showed thrombocytopenia, hyperferritinemia, hypertriglycemia, and the bone marrow biopsy showed hemophagocytosis. Epstein-Barr virus antibody was positive. He responded to chemotherapy as per the HLH-2004 protocol and supportive treatment, and was discharged without complication on day 17.

Chilaiditi syndrome is an extremity rare disease that is typically asymptomatic, but can lead to fatal complications, such as volvulus, perforation, and bowel obstruction. This paper reports a case of an 80-year-old female patient who was admitted for right upper quadrant pain and nausea. She showed a positive Murphy sign with tenderness in the right upper quadrant area. Abdominal ultrasound showed that the gall bladder was normal, but abdominal computed tomography revealed multiple small bowel loops interposed among the liver and diaphragm, as well as an abrupt small transition in the bowel caliber with air fluid levels. Therefore, she was diagnosed with an acute small bowel obstruction by Chilaiditi syndrome. She was managed with surgical repair and was discharged without complications after 18 days of admission. Small bowel obstructions by Chilaiditi syndrome is one etiology of which every emergency physician should be aware.

P u r p o s e: We evaluated the proper length of a central venous catheter (CVC) during subclavian vein catheterization and the usefulness of transthoracic echocardiography in identifying the position of the CVC. M e t h o d s: From August 2002 to September 2002, we studied prospectively 30 consecutive patients who had a CVC inserted. The right subclavian vein was punctured by using the Seldinger method, and the patients were divided into two groups according to the method used to identify the position of the central venous catheter. In the radiology group, after central venous catheterization, we identified the position of the CVC by using a plain chest X-ray; then, we adjusted the length of the catheter. In the echocardiography group, during central venous catheterization, we inserted it deeply enough to observe the tip of the catheter in the right atrium by using echocardiography; then, we withdrew the catheter slowly until it was no longer observed in the right atrium, and we fixed the catheter at that position. We measured the heights, weights, and chest circumferences of the patients. R e s u l t: The maximal lengths of CVCs were 15.9±2.0 cm in the radiology group and 15.9±1.7 cm in the echocardiography group. There was no difference between the two groups (p=0.98). The maximal length of the CVC correlated to the height of the patient (Y=0.154X-9.8: Y=the length of the CVC, X=height, p<0.001, R2=0.394) and to the weight of the patient (Y=0.076X+11.2: Y = the length of the CVC, X=weight, p=0.042, R2=0.140), but not to the chest circumference (p= 0 . 3 7 1 ) . C o n c l u s i o n: Echocardiography was a useful method in identifying the optimal positioning in central venous catheterization. The maximal length of the CVCs was 15.9 ±1.9 cm via the subclavian vein approach in Koreans and correlated to the height of the patients.

Background: Trauma-induced deaths can be prevented by implementation of trauma system during prehospital phases and in-hospital phases. To reduce the preventable death rate (PDR), it is essential to improve the treatment strategy during the prehospital phases and the in-hospital phases. This study was designed to compares the prehospital death and emergency department (ED) death in a city before and after implementation of trauma system. Method: We evaluated the prehospital and ED data of 106 trauma patients who had died in 1991 and 2001. Trauma deaths were reviewed and the preventability of those deaths was judged by three professional panels according to appropriateness of diagnosis and treatment in prehospital phases and in-hospital phases. Deaths were classified as preventable and nonpreventable. We compared the preventable death of 1991 with those of 2001. Result: Trauma patients were 993 in 1991 and 3,094 in 2001. Trauma-induced deaths were 60 in 1991 and 46 in 2001. The death rate decreased from 6% in 1991 to 1.5% in 2001 (p<0.001). Death rate by traffic accident decreased from 90% (54/60) in 1991 to 67% (31/46) in 2001 (p<0.001). The PDR decreased from 40% (24/60) in 1991 to 13% (6/46) in 2001 (p<0.001). The time elapsed from the scene of accident to ED arrival decreased from 111 minutes in 1991 to 53 minutes in 2001 (p<0.001). There was no significant difference in Injury Severity Score between 1991 and 2001 (p=0.283). Conclusion: The rate of preventable death decreased from 1991 to 2001. Implementation and improvement of the trauma system has positive effects on trauma-induced death rate, PDR and the time elapsed from the scene of accident to ED arrival.

4차산업혁명에서 전문서비스업의 변화와 감정평가의 역할

감정평가는 불완전시장에 대한 공적 개입의 일환으로서, 균형가격 등 정상적인 시장정보를 생산하고 시장의 기능을 보완하는 역할을 수행해왔다. 그러나, 부동산 정보가 다양한 빅데이터와 융ㆍ복합되면서 자동평가모형이 개발되는 등 시장참가자에 의한 가격 접근성이 향상되고 있으며, 이는 감정평가에 대한 회의로까지 이어지고 있는 실정이다. 빅데이터에 기반한 자동평가모형의 도입은 감정평가정보의 사적 활용과 경합할 것으로 예상되나, 과세, 보상, 담보 등 국민의 재산권 및 시장안정성을 보호하는 역할을 수행하는 공적 감정평가활동의 대체는 제한적일 것으로 판단된다. 그러나, 전문지식의 누적성과 비경합성에 의한 시장 환경의 변화는 향후 감정평가업의 능률화, 체계화를 견인하는 외부적 압력으로 작용할 것이다. 감정평가사는 가치평가 전문지식을 개발하고 관리하면서, 시장참여자들이 이를 활용할 수 있게 돕는 것이다. 방대한 양의 공공데이터와 가격정보의 개방은 필연적이므로, 빅데이터를 포용하고 해석하지 못한 감정평가정보는 시장의 신뢰와 무관하게 시장의 인지도를 상실할 것이다. 감정평가사는 누구보다 먼저 빅데이터를 받아들이고 관리하면서, 국민에게 혜택을 주는 다양한 부동산정보를 생산하고 무작위적 시장정보에 대한 관리자로서의 위상을 세워야 할 것이다. Property appraisal has been responsible for producing market information and supplementing the function of market as a part of public intervention on the imperfect market. Recently, emerging various big data services for real-estate markets become a threat for property appraisal industry. The introduction of the automatic evaluation model based on the big-data is expected to compete with existing property appraisal services in the private sector. Its substitution on public appraisal activities, such as property taxation, might be limited in order to ensure property rights, but big-data in the real-estate market could be an external pressure to streamline and systematize the appraisal business. Since the opening and sharing of public data and price information is inevitable, appraisal information that does not embrace and utilize big data will lose market competitiveness. Therefore, property appraisers should accept and manage big data actively, produce various real estate information for the people, and strengthen their position as a real estate market information specialist.
