Antiphospholipid syndrome (APS) is a thrombophilic disorder characterized by recurrent abortion, thrombocytopenia, and prolonged activated partial thromboplastin time (aPTT) in which venous or arterial thrombosis, or both, may occur in patients with antiphospholipid antibodies. Antiphospholipid antibodies have been associated with a variety of neurological disorders, many of which, but not all are manifestations of cerebral or ocular ischemia. Recently, we experienced one case of a cerebral infarct due to APS in a 24-year-old female. She visited the emergency department and presented with dizziness and vomiting. After admission, we conducted a physical examination, blood tests, and brain computed tomography. Her blood tests revealed prolonged aPTT and thrombocytopenia, and brain computed tomography showed a right cerebellar and pons infarct. We treated her with anticoagulants. She was discharged with nearly a full recovery on the seventh hospital day.

P u r p o s e: This study was conducted to evaluate the etiology and the efficacy of diagnostic tools such as physical examination, laboratory studies, cranial computed tomography (CT) scans, and electroencephalograms (EEGs) in adult patients presenting with new-onset seizure in an emergency department. M e t h o d s: This is a retrospective study of a 4-year period during which 67 patients were admitted to an emergeny department complaining of new-onset seizure. Among them, 61 patients were eligible for inclusion in this study, and we reviewed their medical records, laboratory data, CT scans and EEG findings. R e s u l t s: The etiologies of new-onset seizure were 1) unknown, 2) alcohol withdrawal, 3) ischemic stroke, and 4) central nervous system infection. An abnormal CT lesion was diagnosed in 27.5% of the patients with normal neurological examinations. An abnormal CT lesion was diagnosed in 30% of the patients whose EEG results had a focal-wave pattern. But, No statistical significance could be attached to the relationship between the CT lesion and EEG results (p> 0 . 0 5 ) . C o n c l u s i o n s: The principal etiologies of new-onset seizure were 1) unknown, 2) alcohol withdrawl, 3) ischemic stroke. A CT scan should be performed in all patients with newonset seizure. A focal-wave pattern in the EEG may consider a necessity for brain imaging.

Purpose: This study analyzed the general features, psychiatric histories, past suicidal attempts and psychiatric diagnoses of suicide victims admitted via the emergency department (ED). Methods: Reviewing the charts of 138 inpatients of suicide attempts admitted via the ED from January 2002 to December 2003, we analyzed various data, including sex, age, season, stressful events, psychiatric histories, previous suicidal attempts, and psychiatric diagnoses during admission, and we used a chi-square test to chart the statistical data. Results: A significant difference was found between 1 st attempts and repeated attempts as to the mechanical methods used for the suicide attempts, There was a significant difference in the kinds of drugs between patients with and without psychiatric histories. In the psychiatric diagnosis, there was a significant difference in AXIS I between patients with and without psychiatric histories. In AXIS II, there was a significant difference between patients with and without psychiatric histories, 1st attempts and repeated attempts. Conclusion: We emphasize the importance of psychiatric consults, treatments, and follow-ups for suicide victims and the emergency physicians' function in helping them to contact psychiatric doctors.

PURPOSES : The purpose of this study was to evaluate the performance of rapid-setting polymer-modified asphalt mixtures with a high reclaimed asphalt pavement (RAP) content. METHODS: A literature review revealed that emulsified asphalt is actively used for cold-recycled pavement. First, two types of rapid-setting polymer-modified asphalt emulsion were prepared for application to high-RAP material with no virgin material content. The quick-setting polymer-modified asphalt mixtures using two types of rapid-setting polymer-modified asphalt emulsion were subjected to the following tests: 1) Marshall stability test, 2) water immersion stability test and 3) indirect tensile strength ratio test. RESULTS AND CONCLUSIONS : Additional re-calibration of the RAP was needed for laboratory verification because the results of analyzing RAP aggregates, which were collected from different job sites, did not deviate from the normal range. The Marshall stability of each type of binder under dry conditions was good. However, the Type B mixtures with bio-additives performed better in the water immersion stability test. Moreover, the overall results of the indirect tensile strength test of RAP mixtures with Type B emulsions exceeded 0.7. Further research, consisting of lab testing and on-site application, will be performed to verify the possibility of using RAP for minimizing the closing of roadways.

Purpose: The purpose of this study was to observe the success rate, the average of total administration doses and the complications associated with a convenient method of adenosine admininstration for paroxysmal supraventricular tachycardia (PSVT). Methods: A non-blind, randomized, prospective study was conducted during the 30 months from January 1999 to June 2001. We enrolled 65 cases during this period. The number of cases in the standard method group was 35, and that in the mixed method group was 30. In the standard method group, 6 mg of adenosine was administered intra venously; therefore, 15~20 ml of normal saline was immediately flushed. This method is usually used and recommended. In the mixed method group, 6 mg of adenosine had been previously mixed with 15 ml of normal saline was administered intravenously without any additional manipulation. We evaluated the success rate, the average successful doses, and the complications of each group. Results: The success rate was 80% in the standard method group and 85.7% in the mixed method group, but this difference was not statistically significant (Chi square test, p=0.39). The average of total admininstration doses were 10.3±6.3 mg in the standard method group and 11.0±6.5 mg in the mixed method group, but this difference is not statistically significant (student t-test, p=0.07). There was no remarkable complication in the mixed method group. Conclusion: The mixed method was effective and more convenient than the standard method. A further, larger study is required.

Due to recent industrialization and increasing population, there has been increase in number of accident, which has subsequently led to increase in trauma patients. Blunt abdominal trauma is a supreme challenge to the emergency specialist`s clinical acumen. Historical data may be incomplete, absent, or presumptive. The symptoms and signs can be unreliable and obfuscated by head injury, alcohol, or depressed mental status(1). Although abdominal trauma is common, diagnosis and treatment has always been difficult due to the complex structure of abdomen, despite advance in diagnostic technique. If the patient show peritoneal irritation sign or hemodynamic instability immediately after abdominal trauma, there is need for open surgery to diagnose and to treat peritonitis and hemoperitoneum. However, it is known that patient may show no symptom or sign immediately but may result in delayed bowel perforation which could be fatal for the patient. Therefore we reported a case of peritonitis due to delayed bowel perforation 7 days after abdominal trauma.
