The nephrotic syndrome frequently causes a hypercoagulable state, leading to thromboembolic complications in veins, but arterial thrombosis is relatively rare, and is usually associated with a poor prognosis. We report 50-year-old female patient who presented with minimal change disease complicated with aortic and right iliac arterial thrombosis. She was admitted to our hospital with severe pain in her right leg and left flank. No pulse was palpable in her right femoral artery. Aortography demonstrated a focal eccentric thrombus attached to the left wall of aorta, in which the left renal artery was occluded, and another thrombus obstructing the right common iliac artery. An emergency thrombectomy was performed. Although the patient had satisfactory reperfusion of right common iliac artery, her left renal function was not recovered. A renal biopsy revealed histologic evidence of minimal change of glomerulonephritis. After 8 weeks of steroid therapy, cytoxan was started. After 3 weeks, she developed pneumonitis and died with sepsis. 신증후군에서 혈전 색전증의 빈도는 보고자에 따라 다르지만 막성 신증의 경우 70% 까지도 보고되고 있다1). 위험률을 정확히 예측할 수는 없으나 낮은 알부민 농도, 많은 양의 단백뇨 배출, 높은 fibrinogen 농도, 낮은 antithrombin III 농도, 순환 혈액량 감소 등이 혈전색전증의 합병과 관련이 있다고 알려져 있고1-3) 고위험군에서는 예방적 항 응고 치료를 권유하고 있다2). 동맥에 발생하는 혈전증은 상대적으로 아동에서 더 많이 발생하고 성인에서는 드물며4,5) 예후는 좋지 않다. 신증후군에 합병되는 혈전증의 원인이 되는 요소로는 응고 인자와 섬유소 용해계의 변화로 인한 응고성 항진 상태, 혈소판 수와 기능의 변화, 혈액 농축 및 점도의 증가 등이 있다6). 저자들은 미세 변화 신증후군이 있었던 성인 여자에서 대동맥과 장골 동맥에 혈전증이 합병되었고 이 중 대동맥의 혈전증이 좌측 신동맥 기시부에 위치하여 신경색을 초래한 증례를 경험하였기에 문헌 고찰과 함께 보고한다.

Central catheterization for temporary vascular access in hemodialysis patients may cause serious catheter-related infection such as bacteremia, osteomyelitis, and septic shock. We here report a case of unusual complication of catheter-related infection in a hemodialysis patient with internal jugular catheter. A 44-year old man was admitted due to intermittent fever and right chest discomfort. Five weeks ago, right internal jugular catheter was inserted for hemodialysis. Three weeks ago, He stopped hemodialysis treatment and exit site skin care of the catheter by himself. Chest X-ray showed massive right pleural effusion. But the catherter was normally positioned in superior vena cava. Both blood and pleural fluid cultures demonstrated Staphylococcus aureus. After prompt removal of the catheter and drainage of the pleural fluid, and adequate antibiotic treatment, catheter-related bacteremia and pleural effusion improved.

Purpose: We performed a quantitative and qualitative analysis in the Journal of the Korean Society of Traumatology (JKST) by Bibliometrics to know the trends of articles. Methods: We reviewed articles in the JKST retrospectively through 1988 to 2014. Articles were classified into original articles, case reports, review articles, and also it is further classified as topics and the information related to the Department of Medicine of corresponding author. Original article was classified prospective and retrospective studies. Results: 753 studies and average of 27.9 studies per year were posted on JKST. 576 original articles (76.5%) were posted. Retrospective studies around 449 studies (78%) were posted and there were about 35 descript studies and 541 analytic studies. The most common themes were related to abdominal trauma, 144 pieces, 95 pieces following damage to the chest and the 84 pieces of special order of trauma. Emergency department had the highest case whereas general surgery came to the second place. Conclusion: Recently, there has been reduced proportion of original article in JKST. It was not possible to evaluate the Korea Citation index journals due to the fact that it does not correspond to listed register Journal of National Foundation of Korea. There will be the need for the effort to improve the maintenance of the posted article number, as well as the qualitative development of the posted articles. [ J Trauma Inj 2015; 28: 182-189 ]

Purpose: The rapid recognition of cardiac arrest is an important factor for survival in cardiac arrest patients, and gasping is a primary barrier to the recognition of a cardiac arrest. This study examined differences in capability of recognizing a cardiac arrest and gasping among lay people, hospital nurses, and medical dispatchers. Methods: From January to July 2016, 193 participants (65 lay people 62 hospital nurses, and 66 medical dispatchers) watched video clips of a collapsed virtual patient with unresponsiveness, gasping or seizure and answered a questionnaire asking whether the patient was in cardiac arrest or not. The results of the questionnaire were analyzed and compared among the groups. Results: The total score of the questionnaire on the determination of cardiac arrest among lay people, nurses, and medical dispatchers were significant (3.09±1.43 vs. 4.15±1.22 vs. 4.45±1.29 points, p<0.01). In the questions regarding cardiac arrest with gasping, the correct answer rate was highest in the dispatchers, followed in order by nurses and lay people (82.5% vs. 54.8% vs. 29.7%, p<0.001). Conclusion: In this study, lay people had the lowest recognition capability of a cardiac arrest and gasping among the groups. In addition, gasping is a meaningful barrier to cardiac arrest recognition for both lay people and healthcare providers.

Purpose The dose of drug and the size of instrument are determined based on children’s weight. We aimed to validate the finger counting method (FCM) for weight estimation in Korean children using the Monte Carlo simulation. Methods We estimated the weight of Korean children aged 1 to 9 years by the FCM. These measurements were compared with the weight extracted by the Monte Carlo simulation applied to the “2007 Korean Children and Adolescents Growth Standard.” Pearson correlation coefficients (r) were measured to assess the correlation between the weight extracted by the simulation and that estimated by FCM. Bland-Altman analyses were performed to assess the agreement between the weight extracted by the simulation and that estimated by FCM and 2 other well-known pediatric weight estimation formulas (the Advanced Pediatric Life Support and Luscombe formulas). Results Data regarding 9,000 children’s weight selected by age and gender was randomly extracted using the simulation. We found a positive correlation between the weight estimated by the FCM and the weight extracted (in boys, r = 0.896, P < 0.001; in girls, r = 0.899, P < 0.001). The FCM tended to underestimate weight in the children aged 7 years or old. Conclusion This article suggests the usefulness of FCM in weight estimation, particularly in children younger than 7 years. With appreciation of the limitation in older children, the FCM could be applied to emergency practice. .

Objective: Data mining extracts meaningful information from large datasets. In this study, text mining techniques were used to extract keywords from the Journal of the Korean Society of Emergency Medicine, and the change trend was examined. Methods: The rvest package in R was used to extract all papers published in the Journal of the Korean Society of Emergency Medicine from 2006 to 2016 that could be searched online. Among them, 3,952 keywords were extracted and studied. Using the selected keywords, the corpus was formed by refining keywords that did not correspond to MeSH (Medical Subject Headings) or were misspelled and had similar meanings based on agreement of researchers. Using the refined keywords, the frequencies of the keywords in the first and second halves of the studies were calculated and visualized. Results: Word Cloud revealed that emergency medical service and cardiopulmonary resuscitation (CPR) were most frequently mentioned in both the first and second halves of the studies. In the first half, ultrasonography, stroke, poisoning, injury, and education were frequently mentioned, while in the second half, poisoning, injury, stroke, acute, and tomography were frequently mentioned. A pyramid graph revealed that the frequencies of emergency medical service and CPR were commonly high. Conclusion: Core keywords of the Journal of the Korean Society of Emergency Medicine were analyzed for correlations and trends. Changes in study topics according to key topics of interest and period were visually identified.

Urinary tract infection is one of the causes of acute renal failure. But it has been reported rarely, so we must consider another etiologies before diagnoses. Abdominal ultrasonogram is a good non-invasive technique for radiologic diagnosis or for differential diagnosis, but it`s possible that tiny abscesses and small lesions of focal bacterial nephritis might be missed CT is the best radiologic method to diagnose renal lesion, especially acute bacterial nephritis. Nevertheless, CT has several problems, including contrast-induced nephropathy, exposure to radiation. We experienced a severe form of anuric acuric acute renal failure secondary to acute bacterial nephritis due to E, coli infection, The patient`s renal lession was not visualized on the ultrasonogram and his uremic symptom was severe. So we decided to do a kidney biopsy to find another possible cause of acute renal failure. The renal biopsy finding showed acute bacterial nephritis, and abdominal CT reconfirmed it. His serum creatinine increased to a maximum 8.5 ㎎/dL, but decreased to 1.24 ㎎/dL through continuous antibiotic therapy. We emphasize that urinary tract infection is not a rare cause of acute renal failure any more, and that positive diagnositic approaches, including kidney biopsy, are important for accurate and early diagnosis.
