This study aims to enhance the accuracy of severity classification by examining the usage patterns and characteristics of emergency department visits. It focuses on adult and elderly patients who visited a public hospital in Seoul. This descriptive study retrospectively reviewed the electronic medical records of patients who visited the emergency department of a public hospital between November and December 2023. The total number of participants was 1,033, with 46.4% (n=479) being elderly and 53.6% (n=554) being adults. The chief complaints of the participants were as follows: for the elderly, nervous system symptoms at 8.2% (n=85) and digestive symptoms at 7.5% (n=77) were the most common, while for adults, gastrointestinal symptoms at 11.0% (n=114) and trauma at 8.6% (n=89) were more prevalent. In the case of the elderly, patients classified as urgent accounted for the highest percentage at 23.9% (n=247), while for adults, non-emergency were more prevalent at 32.2% (n=333). The initial severity classification error rate for elderly patients in the urgent was 3.8%, indicating that the suitability of KTAS for elderly patients with high severity was low. To minimize severity classification errors and enhance KTAS accuracy, it's essential to address its current limitation of only classifying adults and children separately by developing a KTAS classification system that reflects the diverse characteristics of elderly patients.

Purpose: Many studies have addressed a psychiatric analysis of self-injury patients who have self-injurious behavior and who have attempted suicide. Few studies on the injury characteristics of self-injury related trauma patients have been conducted. We analyzed the injury characteristics of self-injury patients. Methods: A retrospective review of the medical records extracted from the injury surveillance system of Wonju Christian Hospital for the period from August 2006 to February 2008 was conducted. Of the 121 cases extracted, 103 were included in this study. We analyzed the sex ratio, age group, place of injury, injury mechanism, location of injury, management results, injury severity, and relation with drinking. Results: One hundred three cases were included (sex ratio: 1.06), and the mean age was $33.9{\pm}14.2$ years old. Fifty-six patients (54.4%) were discharged from the emergency department (ED) on the day of injury after primary care, and 9 patients (8.7%) were discharged, because they refused treatment. Seven patients (6.8%) died. Of these, 4 patients (3.9%) died after attempted cardio-pulmonary resuscitation in the ED, 1 patient (1%) was dead on arrival, and 2 patients (1.9%) died after admission. Sixteen patients (15.5%) were admitted to the hospital, including 2 patients (1.9%) needing emergency surgery. Sixteen patients (15.5%) were transferred to other hospitals. Sixty-one cases (59.2%) involved drinking, and 31 (30.1%) did not; for 11 cases (10.7%), the involvement of drinking was unknown. The mean revised trauma score (RTS) was $11.26{\pm}2.52$, and 88 cases (85.4%) hat a RTS of 12. The mean injury severity score (ISS) was $5.80{\pm}14.56$, and 9 (8.7%) severely injured patients had scores of more than 15. Conclusion: Most self-injuries were mild traumas related to drinking and occurred at a young age. Most cases were not so severe, and the patients were discharged from the ED, but some patients needed hospitalization. Other patients had injuries so severe that they died.
Purpose: The aim of this study is to present the basic data for qualitative improvement of emergency care for emergency patient by paramedic in fire station by understanding the level of awareness and practice in prehospital and transfer step, and understanding the level of emergency care and improvement of clinical knowledge through hospital clinical training. Methods: The researchers explained the objective for 143 persons who completed hospital clinical training from June 2nd, 2006 to October 23rd, 2009 among paramedic in fire station. The questionnaire in this research consisted of 80 questions. In the reliability for the awareness of emergency patient assessment, cronbach's $\alpha$ was 0.95, and in the reliability for emergency care fulfillment, cronbach's $\alpha$ was 0.93. reliability for clinical knowledge improvement is cronbach's $\alpha=.95$, and reliability for emergency care fulfillment is cronbach's $\alpha=.82$. Collected data was analyzed through SPSS 18.0 statistics program for frequency, percentage, average, standard deviation, Paired t-test, t-test, Correlation Coefficient, and internal consistency reliability was analyzed by cronbach's $\alpha$. Results: 1) The paramedic awareness and practice difference for emergency patient is statistically signification for general patient assessment(t=14.159, p=.000), trauma patient assessment(t=11.288, p=.000), internal medicine patient assessment(t=10.898, p=.000), and it shows the level of practice is lower than the level of awareness. 2) The paramedic difference between the level of awareness and practice according to whether or not they have clinical career is not signification on awareness(t=3.119, p=.125), and is high on practice(t=3.119, p=.002). 3) The correlation between paramedic awareness and the level of practice shows positive correlation(r=.61, p=.000). The higher the awareness of emergency patient assessment is, the higher the level of practice is. 4) The difference between paramedic clinical knowledge improvement and the level of emergency care practice is statistically significant(t=3.351, p=.001). 5) 89.6%(128 persons) of paramedic replied hospital clinical training experiences are helpful for field activity. 92.3%(133 persons) replied they apply well for clinical knowledge learned during hospital clinical training and emergency care skills in the field. Conclusion: Paramedic in fire station must evaluate the patient's initial assessment and activate the transfer system to the emergency department. It is necessary to develop and implement the effective education program continuously. The education program should systemize currently operated hospital clinical training. emergency disease and symptoms emergency care method, and practice mainly skill education should be progressed. In the prehospital and transfer management, high quality of medical assessment is required to the emergency medical service system. Medical direction from the doctors can feedback the paramedic continuously and continuing education must be provided to the paramedic in fire station.

Purpose: Hypovolemic shock is the leading cause of death in multiple trauma patients with pelvic bone fracures. The purpose of this study was to develop a simple prediction method for injury severity and amount of hemorrhage via an analysis of the correlation between the site of pelvic bone fracture and the amount of transfusion and to verify the usefulness of the such a simple scoring system. Methods: We analyzed retrospectively the medical records and radiologic examination of 102 patients who had been diagnosed as having a pelvic bone fracture and who had visited the Emergency Department between January 2007 and December 2011. Fracture sites in the pelvis were confirmed and re-classified anatomically as pubis, ilium or sacrum. A multiple linear regression analysis was performed on the amount of transfusion, and a simplified scoring system was developed. The predictive value of the amount of transfusion for the scoring system as verified by using the receiver operating characteristics (ROC). The area under the curve of the ROC was compared with the injury severity score (ISS). Results: From among the 102 patients, 97 patients (M:F=68:29, mean $age=46.7{\pm}16.6years$) were enrolled for analysis. The average ISS of the patients was $16.2{\pm}7.9$, and the average amount of packed RBC transfusion for 24 hr was $3.9{\pm}4.6units$. The regression equation resulting from the multiple linear regression analysis was 'packed RBC units=1.40${\times}$(sacrum fracture)+1.72${\times}$(pubis fracture)+1.67${\times}$(ilium fracture)+0.36' and was found to be suitable (p=0.005). We simplified the regression equation to 'Pelvic Bleeding Score=sacrum+pubis+ilium.' Each fractured site was scored as 0(no fracture) point, 1(right or left) point, or 2(both) points. Sacrum had only 0 or 1 point. The score ranged from 0 to 5. The area under the curve (AUC) of the ROC was 0.718 (95% CI: 0.588-0.848, p=0.009). For an upper Pelvis Bleeding Score of 3 points, the sensitivity of the prediction for a massive transfusion was 71.4%, and the specificity was 69.9%. Conclusion: We developed a simplified scoring system for the anatomical fracture sites in the pelvis to predict the requirement for a transfusion (Pelvis Bleeding Score (PBS)). The PBS, compared with the ISS, is considered a useful predictor of the need for a transfusion during initial management.
Purpose: A brain abscess is a serious disease of the central nerve system. We conducted this study to summarize the clinical manifestations and outcomes of brain abscesses. Methods: A retrospective chart review of pediatric patients diagnosed with brain abscesses from November 1994 to June 2009 was performed at Samsung Medical Center, Seoul, Korea. Results: Twenty-five patients were included in this study. On average, 1.67 cases per year were identified and the median age was 4.3 years. The common presenting clinical manifestations were fever (18/25, 72%), seizure (12/25, 48%), altered mental status (11/25, 44%), and signs of increased intracranial pressure (9/25, 36%). A total of 14 (56%) patients had underlying illnesses, with congenital heart disease (8/25, 32%) as the most common cause. Predisposing factors were identified in 15 patients (60%). The common predisposing factors were otogenic infection (3/25, 12%) and penetrating head trauma (3/25, 12%). Causative organisms were identified in 64% of patients (16/25). The causative agents were $S$$intermedius$ (n=3), $S$$aureus$ (n=3), $S$$pneumoniae$ (n=1), Group B streptococcus (n=2), $E.$$coli$ (n=1), $P.$$aeruginosa$ (n=1), and suspected fungal infection (n=5). Seven patients received medical treatment only while the other 18 patients also required surgical intervention. The overall fatality rate was 16% and 20% of patients had neurologic sequelae. There was no statistical association between outcomes and the factors studied. Conclusion: Although uncommon, a brain abscess is a serious disease. A high level of suspicion is very important for early diagnosis and to prevent serious consequences.

Purpose: In Ulleung island, emergency medical transport by helicopter is very important. So, we analysized our experience with emergency medical transport by helicopter for 4 years and we were compared our data with other data for 1997-2001. Therefore we need to research public health development direction. Method: We analysized patient's medical record for 4 years. Result: During 4 years, 104 transports were done and 130 patients were trasported to tertiary hospital center, there was more increased than that from 1997 to 2001. Helicopters from Pohang coast guard, Donghae coast guard, Navy, and 119 rescue etc. were used, but 119 rescue transport was decreased more and more. The 60's patients was most, 22.3% and teenager's and 80's patients was lowest. The male was 65% but the female was increased more and more annually. In addition, the older patients was the more portion of female patient. The transport was concentrated in daytime. The traumatic patient was much in winter period. The cerebrovascular accident was 1st cause of patient and fracture was many also. Conclusioon: Except Fire service's helicopter, the other helicopter was not apt to emergency medical tansport. But Fire service's helicopter was not used commonly because Fire service's helicopter was in Daegu, so distant and time consumed. As a result, emergency medical transport helicopter is needed in east coast like Fire service's helicopter. In addition, trauma prevention education and public health education for hypertension and diabetes will be essential and public health system in Ulleung island will be prepared for aging society.

In emergency cases, such as the severe trauma involving the fracture of skull, spine, or cervical bone, from auto accident or a fall, and/or pneumothorax which can not be diagnosed exactly by the eye examination, it is necessary the radiological examination during transferring to the hospital for emergency care. The aim of this study was to design and evaluate the prototype of mobile medical image communication system based on CDMA 1X EVDO. The system consists of a laptop computer used as a transmit DICOM client, linked with cellular phone which support to the CDMA 1X EVDO communication service, and a receiving DICOM server installed in the hospital. The DR images were stored with DICOM format in the storage of transmit client. Those images were compressed into JPEG2000 format and transmitted from transmit client to the receiving server. All of those images were progressively transmitted to the receiving server and displayed on the server monitor. To evaluate the image quality, PSNR of compressed image was measured. Also, several field tests had been performed using commercial CDMA2000 1X-EVDO reverse link with the TCP/IP data segments. The test had been taken under several velocity of vehicle in seoul areas.
Transplantation would be the only way to cure the end-stage organ failure involving heart, lung, liver, kidney and pancreas. The replacement of the parts of the body damaged to lose its function or lost to trauma must be a dream of human-being. Human history is replete with chimeras, from sphinxes to mermaids, making one wonder if the ancients might actually have dreamed of what now is called 'xenotransplantation'. In the 20th century, the transplantation of organs and tissues to cure disease has become a clinical reality. The development in the fields of surgical techniques, physiology and immunology attributed to the successful transplantation in human. In the center of the successful transplantation lies the progress in understanding the cellular and molecular biology of immune system which led to the development of immunosuppressive drugs and the invention of the concept of immunological tolerance. The mandatory side effects of immunosuppressive drugs including infection and cancer forced us to search alternative approaches along with the development of new immunosuppressive agents. Among the alternative approaches, the induction of a state of immunologic tolerance would be the most promising and the most generic applicability as a future therapy. Recent reports documenting long-term graft survival without immunosuppression suggest that tolerance-based therapies may become a clinical reality. Last year, we saw the epoch making success of overcoming hyperacute rejection in porcine to primate xenotransplantation which will lead porcine to human xenotransplantation to clinical reality. In this review, I dare to summarize the development of transplantation immunology from the perspective of history.
Treatment of chronic subdural hematoma (CSDH) is relatively straightforward, however, there is still some debate regarding the best strategy for treatment. The most practical recommendations of up to date were identified by a review of literature. The author reviewed the literature on CSDH management from the past to now to identify the best methods. Till 1970s, craniotomy was the most commonly used method. Burr hole (BH) became the most preferred method from 1980s. In 1977, twist drill (TD) craniostomy was introduced. Closed system drainage after a BH or a TD became the most frequently used surgical method. Although nonsurgical treatment is often successful, trephination has more advantages, such as rapid resolution of the symptoms and short period of hospitalization. Nonsurgical treatment is possible in asymptomatic patients with a small CSDH. For the symptomatic patients with CSDH, trephination is the treatment of choice, either by BH or TD. In gray zone between surgery and medical treatment, shared decision making can be an ideal approach. For the recurrent CSDHs, repeated trephination is still effective for patients with a low risk of recurrence. If the risk of recurrence is high, additional management would be helpful. For the refractory CSDHs, it is necessary to obliterate the subdural space.

C1q nephropathy is a rare glomerulopathy that typically presents with nephrotic syndrome in children. Treatment with immunosuppressive agents renders patients vulnerable to infection and its complications. Gastroenteritis is common in children, and rotavirus is a leading cause. Extraintestinal manifestations of rotavirus have recently been reported; however, there is a paucity of cases exploring the involvement of a rotavirus on the respiratory system. Acute respiratory distress syndrome (ARDS) is a rapid onset respiratory failure characterized by noncardiogenic pulmonary edema and hypoxemia. Causes of ARDS include sepsis, pneumonia, pancreatitis, aspiration, and trauma. In this paper, we report a case of ARDS after rotavirus infection in a child with C1q nephropathy who had been treated with immunosuppressive agents.
