BACKGROUND: Care for prehospital cardiac arrest is one of the major concerns of emergency medical services. But, in Korea, prehospital emergency medical service systems are not yet well established. We tried to offer one of the fundamental data for development of these systems. METHODS: After application of exclusion criteria, 183 patients who transferred to emergency center of our hospital after cardiac arrest in consecutive 24 months from Jan,1,1994 to Dec,31,1995 were included in this study. Retrospective review of the hospital charts of these patients was done. For statistical analysis, we divided patients to some categories. t-test or chi-square analysis was used. RESULTS: 24 patients of the 183 patients were secondary visitors(cardiac arrest was occurred during transfer from other hospitals), 159 patients were primary visitors. In the primary visitor group, only one third was ambulance visitors, and there is no statistical differences between arrest time of ambulance visitors and non-ambulance visitors(35+/-27 vs 37+/-24 min, p=NS). No organized bystander CPR was done. After arrival, 131 patients received CPR and 87 patients(66.4%) were not responded, 31 patients(23.1%) experienced transient ROSC, 13 patients(10.0%) survived until discharge, and only 2 patients(1.5%) were returned to their lives. CONCLUSION: We failed to find significant statistical survival differences between ambulance visitors and non-ambulance visitors, between presumed cardiac etiology group and non-cardiac etiology group. Survival rate was high in witnessed arrest group than unwitnessed arrest group(14.5% vs 2.1%, p=0.015).

2.Background and progress of regional trauma center development.
Journal of the Korean Medical Association 2016;59(12):919-922
In a modern medical delivery system, it is very difficult to provide adequate, timely, and equitable medical care for severely injured patients. Trauma is a leading cause of deaths under the age of 40 and a source of expensive socioeconomic losses in Korea. Korean government has been making a major effort to establish a trauma system since 2000, but inadequacies of the current trauma system still result in many preventable deaths from accidental injuries. The designation and support program for regional trauma centers is the first step in a national plan for trauma system development. At present, there are 9 regional trauma centers and 7 candidates for trauma centers. Regional trauma centers must play a key role in a regionally inclusive trauma system that integrates emergency medical services systems and healthcare delivery systems to deliver optimal medical care for injured patients.

The branch retinal vein occlusion is the second most common retinal vascular disease after diabetic retinopathy. Complications such as macular edema, retinal neovascularization, vitreous hemorrhage, epiretinal membrane may be associated. But, the retinal detachment may occur rarely in BRVO patients. We studied the clinical features of retinal detachment associated with branch retinal vein occlusion. We reviewed the medical records of 15 retinal detachment patients associated with branch retinal vein occlusion. Mean age was 54.7 years old and 10 patients(66.7%) were female. Hypertension was associated in 13cases(86.7%). The duration between the development of BRVO and the development of retinal detachment was shorter than 4 years in all cases and shorter than 2 years in 9 cases(60.0%). Retinal break was identified in 14 cases(93.3%), among which 13 cases(92.2%) were located inside the lesion of branch vein occlusion. The epiretinal membrane was frequently combined 8 cases(53.3%). The preoperative laser photocoagulation was done in 4 cases(26.7%). The primary surgical procedures included scleral buckling in 8 cases(53.3%), pars plana vitrectomy in 6 cases(40.0%), and scleral buckling with pars plana vitrectomy in 1 case(6.7%). Three cases(20.0%) required reoperations. The postoperative complications included the progression of cataract in 6 cases(40.0%), iatrogenic retinal tear in 3 cases(20.0%), epiretinal membrane in 2 cases(13.3%), and proliferative vitreoretinopathy in 1 case(6.7%). The anatomic retinal reattachment was achieved in 14 cases(93.5%) and the visual recovery in 11 cases(73.3%).

Journal of the Korean Pediatric Society 2002;45(11):1411-1416
PURPOSE: Although the use of intravenous gamma-globulin(IVGG) in Kawasaki disease(KD) is effective in reducing clinical symptoms and coronary artery complications, 20-30% of patients have persistent or recrudescent fever and ongoing clinical symptoms. In these patients, the additional infusion of IVGG is considered. The authors studied the characteristics of patients who received IVGG retreatment, and compared them with the patients who did not need IVGG retreatment, for determination of IVGG retreatment. METHODS: We reviewed the medical records of 117 KD patients who could be followed up at least six months. We studied the conventional laboratory findings, electrocardiogram(EKG), signal averaged ECG(SAECG) and echocardiogram. RESULTS: Twenty three patients had early cardiac complications during the six months of follow-up. Four patients had late cardiac complications after six months. The early cardiac complication rate was higher in the IVGG retreatment group than the single infusion group(P<0.0001). The late complication rate was also higher in the retreatment group(P<0.0001). The patients who received methyl-prednisolone(m-PD) pulse therapy had much higher rates of early and late cardiac complications than those who received a single IVGG infusion. Among the clinical data and laboratory findings, only CRP increased significantly in patients who have had the cardiac complications. The IVGG retreatment group had increased CRP than the single infusion group. CONCLUSION: The patients with increased initial CRP may have an increased incidence of complications and an increased possibility of IVGG retreatment. We thought that retreated KD patients might have inflammations severe enough to need high dose IVGG as shown by high CRP levels, and IVGG retreatment could not prevent coronary artery lesions sufficiently.

The reliability of emergency ultrasonographic(US) detection of hemoperitoneum and solid organ injury in blunt abdominal trauma was evaluated retrospectively. From October 1,1995 to August 31,1996,90 patients were included in the study. Ultra- sonographic findings showed a sensitivity, specificity, and accuracy of 97.6%, 97.9%, and 98.1%, respectively, in detecting intraabdominal fluid collection. We believe that US in an emergency center is a quick, safe screening method in the evaluation of blunt abdominal trauma. In our department, US has replaced diagnostic peritonaeal lavage(DPL) and computed tomography(CT) as the screening study of first choice.

PURPOSE: Plasma cholinesterase is a sensitive measure determining the severity of organophosphate intoxication. The author evaluated the usefulness of the plasma cholinesterase level as a prognostic indicator of the severity of organophosphate intoxication. METHODS: From June 1999 to May 2001, 55 patients presented with organophosphate insecticide intoxication to the Emergency Medical Center of the Chonnam National University Hospital, and these were enrolled in this study. The plasma cholinesterase activities of these 55 patients were determined at the time of presentation. The relationships between the plasma cholinesterase level and the clinical variables of organophosphate toxicity, quantity of ingested poison, elapsed time to gastric lavage, and the APACHE score at the time of hospitalization were analyzed. RESULTS: The plasma cholinesterase activity significantly decreased in association with the degree of toxicity of the poison (p<0.001), elapsed time to gastric lavage (p<0.001), and the quantity of organophosphate ingested (p=0.013). In the 55 patients, lower plasma values of cholinesterase were observed in patients with longer durations of mechanical ventilation (r=-0.717, p<0.001) and in patients who developed pneumonia during treatment (r=-0.538, p<0.001). Also, decreased cholinesterase activity correlated with a higher APACHE score (r=-0.672, p<0.001). CONCLUSION: These results suggest that immediate determination of the plasma cholinesterase level at the time of hospitalization may be useful as a prognostic indicator in patients with organophosphate intoxication.

Cardiac arrest (CA) in children is associated with high mortality rates. In Korea, cohort studies regarding the outcomes of pediatric CAs are lacking, especially in emergency departments (EDs) or in-hospital settings. This study was conducted to examine the trends in epidemiology and survival outcomes in children with resuscitation-attempted CAs using data from a cross-sectional, national, ED-based clinical registry. We extracted cases in which cardiopulmonary resuscitation and/or manual defibrillation were performed according to treatment codes using the National Emergency Department Information System (NEDIS) from 2008 to 2012. The total number of ED visits registered in the NEDIS during the 5-yr evaluation period was 20,424,530; among these, there were 2,970 resuscitation-attempted CAs in children. The annual rates of pediatric CAs per 1,000 ED visits showed an upward trend from 2.81 in 2009 to 3.62 in 2012 (P for trend = 0.045). The median number of estimated pediatric CAs at each ED was 7.8 (25th to 75th percentile, 4 to 13) per year. The overall rates for admission survival and discharge survival were 35.2% and 12.8%, respectively. The survival outcome of adults increased substantially over the past 5 yr (11.8% in 2008, 11.7% in 2010, and 13.6% in 2012; P for trend = 0.001); however, the results for children did not improve (13.6% in 2008, 11.4% in 2010, and 13.7% in 2012; P for trend = 0.870). Conclusively, we found that the overall incidence of pediatric CAs in EDs increased substantially over the past 5 yr, but without significantly higher survival outcomes.

Tissue array contains hundreds or thousands tissues from different cases, and has been known useful for rapid analysis of markers in a large numbered work. This has mainly been used in investigative purpose, and few has been reported for diagnostic trial. Diagnosis of early myocardial infarction is important in medicolegal field. Immunohistochemical staining using various antibodies has become a popular tool for this purpose, but standardization and reproducibility have been problems. Use of tissue array is promising in this points. We have made two cardiac tissue arrays using 87 different cases and have verified the feasibility of tissue array in forensic field. Experiences and several issues concerning tissue array are discussed.

We analyzed records at Chonnam university hospital from Sep. 1. 1993 to Aug. 31. 1996 to assess clinical significance of the foreign body in the gastrointestinal tract. There were 133 episodes consisting of 79 pediatric and 54 adult patients as possible to review. In the pediatric patients, the coin was the most common cause of foreign body ingestion, while adult patients were usually caused by bones and meat. We removed foreign bodies in the oral cavity and oropharynx in 12 cases using direct laryngophanmgoscpy and forcep. Endoscopy was performed successfully in 47 of 51 patients in which was attempted; there were two complications composed of an aspiration pneumonia and a mediastinitis due to esophageal perforation. There were spontaneous passage of foreign bodies in 48 cases. We observed complications in 6 cases in which 4 cases needed operations due to complications. Foreign bodies which pass into the stomach can be observed for development of complications, as 94% of foreign bodies which reach the stomach spontaneously pass. Only 4 patients required interventions, which was done without mortality.
