BACKGROUND: Recently, the incidence of acute myocardial infaction has been gradually increasing as prolongation of life spans and improvements of diet and life styles in Korea. The rate of mortality and sudden death is higher than other diseases. The purpose of this study is to evaluate factors which can affect on the mortality of AMI during initial 24 hrs. METHODS: A retrospective clinical study was done on 364 consecutive patients with AMI who had been presented to Keimyung University Dong-sang Medical Center from January 1990 to May 1997(M:F ratio=254:110). The subjects were divided two groups. The Group I was patients who had expired during the initial 24hrs period of AMI(47 patients, 13%), the Group II was patients who had survived(317 patients, 87%). We compared clinical features, EKG, laboratory results in both groups and tried to analyse the vulnarable factors. RESULTS: The results were as follows; 1) The mean age in Group I (64.4 yearly) was older than in Group II(61.3 yearly) and female gender was also higher in Group I. The mean systolic/diastolic blood pressures of the Group I(103/61mmHg) were lower than those of the Group II(123/75mmHg). 2) The chest pain and mental change were noted more frequently in Group I than in Group II and the dyspnea was less frequent in Group I than Group II. 3) The higher grades of Killip classification was significantly more frequent in Group I than in Group II. 4) The mean onset to drug time for thrombolytics in Group I and Group II were 14.1 hrs and 6.6 hrs. 5) The mortality rate of the Group I and the Group II were respectively 13%, 6.6%. The most common causes of death were cardiogenic shock and ventricular arrhythmia. CONCLUSION: The mortality rate of initial 24 hrs of onset as form of sudden death was higher than post-24hrs group(66.2%). The factors for the higher mortality group were old age and female gender, and they were unstable in vital signs, higher Killip classifications. Therefore, these groups demand more rapid and aggressive approach than the other groups.

In general, pelvic fracture carries higher mortality especially from motor veicle accident, we have retrospectively reviewed charts and radiographs of 185 patients in order to identify clinical fading, kinds of fracture, hemodynamic changes and associated injuries in patients with pelvic fractures. We attempted to classify pelvic fractures according Young classification. The following results were obtained; 1. On age and sex distribution, the pelvic fractures showed peak incidence between 2nd decade and 5th decade. Male was affected more frequently than female, the ratio being male to female, 2.6 to 1. 2. The mechamisn of injury was motor veicle accident in 155(83.8%), fall in 25(13.5%), others in 5(2.7%). 3. The associated injuries of pelvic fractures: extremity, thoracic, urinary system, intraperitoneal and head injury. 4. Of the 185 cases of the pelvic fractures, simple pelvic fractures are 101 cases(54.6%), lateral compression in 39(21.1%), anteroposterior compression in 18(9.7%), vertical shearing in 17(9.2%), mixed pattern in 10(5.4%). 5. Retroperitoneal hematoma and urinary tracts injuries were the most common associated in mixed pattern. 6. The incidence of hemodynamically unstable fractures were 19.8% in simple pelvic fracture but, as expected was higher in major pelvic ring disruptions except to acetabular fracture(52.4%). 7. Mortality rates were 5.9% in all pelvic fractures but 10.7% in major pelvic ring disruptions except to acetabular fractures. Prognostic factor in pelvic fractures were the amount of hemorrhage and associated injuries, therefore early diagnosis and managements are essential to reduce the mortality in pelvic fracture.

As the incidence of acute myocardial infarction been increasing with prolongation of life spans, improvement in foods and life styles in Korea, rapid diagnosis and treatment is critical in survival of acute myocardial infarction patient. Most of the acute myocardial infarction result from atherosclerotic plaque forming thrombus and occlusion of coronary artery. Because early thrombolytic therapy is important to maintain the left ventricular function and survival rate, there have been many trials to reperfuse the occluded coronary artery. We have studied the many aspects of acute myocardial infarction such as sex, age, infarction site, chief complaints, change of ECG, change of serum enzyme, time delay on emergency room arrival, and compared the effectiveness of thrombolytic therapy. Total number of patient was 212, and males were 141(66.5%) and females were 71(33.5%). The most common infarction site was ant, fuel wall(102 cases,48%)of the heart and the most common chief complaint was chest pain(204 cases,97%). Among the 106 patients who received thrombolytic therapy, 101 patients(95%) had survived and 5 patients(5%) had died. Among the 64 patients who didn't receive thrombolytic therapy, 56 patients (87.5%) were alived and 8 patients(12.5%) were dead.

Tuberculomas in the spine are estimated to be 15 to 50 times less common than those occurring in the cranium. We experienced a case of intramedullary spinal tuberculoma and brain tuberculoma associated with pulmonary tuberculosis. A 39-year-old male was referred to the National Medical Center via emergency room because of urinary difficulty and lower limb weakness for 3 days. He had been treated with anti-tuberculosis regimens against pulmonary tuberculosis for 20 days. Spinal MRI revealed intradural intramedullary tuberculoma at T5. On the 21st day at the hospital, a generalized seizure attacked him. Brain MRI revealed multiple tuberculoma in both hemispheres, brainstem and cerebellum. He was treated anti-tuberculosis regimens and corticosteroids for 9 months. His condition improved clinically and radiologically. We report this case with a review of the literature.

PURPOSE: We performed this study to identify the clinical characteristics of delirium tremens in Korea. METHODS: We reviewed the charts of patients suffering from delirium tremens who visited the Emergency Department of Keimyung University Hospital during the period of Jan. 2001 through Jun. 2002. RESULTS: All patients were mail, and the number was 28. The age distribution was 40~49, and the most common duration of drinking (15 cases) was between 11 and 20 years. The abstinence period before development of Delirium Tremens was, in most cases, less than 4 days, and the average period of symptoms of Delirium Tremens was less than 6 days. Various abnormal laboratory finding were noted: increased bilirubin level in 50%, prolonged pro-thrombin time in 14.3%, increased amylase level in 19.9% and electrolyte imbalance in 25%. CONCLUSION: During the study period, there was no mortalities. The author believes that sufficient vitamins and fluid supplement contributed to the results.

BACKGROUND: Phantom limb sensation is an unusual position sense of the extremity during nerve block that the position of extremity is misinterpreted as being flexed, or elevated, when actually they are in neutral position. Whether it is from the fixation of proprioceptive input at the time of motor blockade or from unmasking of the pattern which has been already present in the CNS is still controversial. We perfomed this study under the assumption that phantom limb sensation can still be reproduced without the influence of position at the time of nerve blockade. METHODS: Thirty-six patients scheduled for elective orthopedic surgery were randomly assigned. For 26 patients, spinal anesthesia was performed with hyperbaric 0.5% tetracaine or bupivacaine at lateral decubitus position and the position was changed to supine immediately. Existence of phantom limb sensation and the level of anesthesia was recorded at 10 and 20 minutes after injection of local anesthetics. For 10 patients, same local anesthetics were injected after patient's legs were straightened in lateral decubitus position. RESULTS: Forteen out of 26 patients whose position were changed to supine immediately after the injection of local anesthetics experienced phantom limb sensations. Five out of 10 patients whose legs were kept straight before the injection of local anesthetics experienced phantom limb sensations. Previous history of trauma was positively related to the expression of phantom limb sensation. CONCLUSION: Our data showed that the expression of phantom limb sensation is reproducible. And this was not related to the position at the time of spinal anesthesia. Trauma seems to be an important factor related to the expression of phantom limb sensation.

BACKGROUND: The differentiation between hemorrhagic(HS) and norhemorrhagic(NHS) stroke is the most important first step in the management of acute stroke because clinical management of the two disorders differs substantially. Neuroimaging studies are useful in diagnosing and distinctioning between HS and NHS. The use of clinical variables, such as Siriraj stroke scores(SSS), has led to good sensitivity, specificity and predictive values. The aim of our study was to evaluate the use of the SSS in the Korean population and assess whether it could aid to expedite treatment decisions. METHODS: We reviewed 111 cases of stroke patients admitted to our hospital via the emergency department over a 6 months period from July to December 1998. Levels of consciousness, vomiting, headache, and atheroma markers used in the SSS were applied to these patients who met the criteria for a stroke. RESULTS: Of the 111 patients, the SSS classified 83 with sensitivities of 81.1%(NHS) and 73.3%(HS) and positive predictive values of 84.3% and 68.8%, respectively. The overall accuracy rate was 78.3%. CONCLUSION: Our results suggest that the SSS is not reliable in distinguishing stroke types in the Korean population. Definite neuroimaging studies are needed prior to thrombolytic therapy.

BACKGROUND: Good documentation of electrical injuries at the time of presentation is very important to emergency management, so this study was designed to investigate the clinical characteristics and the outcomes of patients with electrical injury. METHODS: A review of 75 cases of electrical injuries admitted to our hospital via the emergency department over a 4 year period from 1996 to 1999 was conducted. RESULTS: There were 49 patients with high-voltage injuries and 19 patients with low-voltage injuries. All but 4 patients were males, with a mean age of 29.5 years. The most common type of injury was 14.5% TBSA in the high-voltage group and 2.5% in the low-voltage group. Forty-nine(72.1%) of the injuries were work related. The number of patient with compartment syndrome was 19, and fasciotomies were performed in all but one patient. Myoglobinuria was noted in 22 patients, but no patient developed acute renal failure due to myoglobinuria. In the high-voltage group, 10 limb amputations were performed. Complication were observed in 12 patients. The most common complication was neurological injury. The average length of hospital stay was 50.7 days in the high-voltage group and 13.8 days in the low-voltage group. The overall mortality rate was 4.3%. CONCLUSION: Prevention of electrical injuries is very important. Education and compliance with safety measures, as well as basic knowledge and precaution in dealing with electricity, are essential to avoid these injuries.
