PURPOSE: Tetanus is still one kind of major health problem in many countries, so tetanus prophylaxis is very important. However medical interview and wound description are not always enough to determine the tetanus prophylaxis. Thus, we assessed the utility of Tetanos Quick Stick(R) test for selective tetanus prophylaxis in the emergency department. METHODS: From September 17, 2003 to October 4, 2003, 180 patients were studied for 14 days. Tetanos Quick Stick (R) and ELISA (enzyme-linked immunosorbent assay) were performed with 180 samples from 180 patients. RESULTS: The Tetanos Quick Stick(R) had a sensitivity of 79.6%, a specificity of 99.2%, a positive predictive value of 97.7 %, a negative predictive value of 91.9%, and an accuracy of 93.3%. CONCILUSION: The results of our study revealed that the Tetanos Quick Stick(R) test is useful for selective tetanus prophylaxis in the emergency department.

BACKGROUND: Community-acquired pneumonia (CAP) is one of the leading causes of mortality and morbidity, but its management is still challenging. The limitations of diagnostic methods to identify etiologic agents rapidly make it necessary to use empiric antibiotics in almost all patients, and furthermore the discovery of new respiratory pathogens and the emergence of antibiotic-resistant organisms pose difficulties to the selection of an empiric antibiotic regimen. To clarify the factors necessary for the optimal choice of empirical antibiotics, such as the frequency of etiologic agents, the attributable rates to death and antimicrobial resistance rates in the community, six university hospitals in Seoul and one university hospital in Cheonan were participating in this study. METHODS: Medical records of adults (> 15 years of age) hospitalized for CAP or pulmonary tuberculosis between March 1995 and February 1996, were reviewed. Patients who satisfied all of the following criteria were included in the study: (1) fever or hypothermia; (2) respiratory symptoms; and (3) pulmonary infiltrates on chest roentgenogram. To exclude cases of pulmonary tuberculosis whose roentgenographic features were so typical that it could be easily differentiated from conventional pneumonia, two additional criteria were required for inclusion: antibiotic treatment during the first week of hospital admission and initiation of anti-tuberculosis medications thereafter. Organisms isolated from sterile body sites, acid-fast bacilli or Mycobacterium tuberculosis isolated from sputum, pathogens diagnosed by a 4-fold rising titer to "atypical" pathogens, or pathogens revealed by histopathology were defined as definitive cause of pneumonia; isolates from sputum with compatible Gram stain, pathogens diagnosed by a single diagnostic titer plus use of a specific antimicrobial agent, or tuberculosis diagnosed by clinical response to anti-tuberculosis medications were considered probable cause of pneumonia. The records of the clinical microbiology were reviewed for isolates of S. pneumoniae, H. influenzae, M. catarrhalis, Mycobacterium or acid-fast bacilli, and mycoplasma. Then the frequency of these agents, antimicrobial resistance rates of respiratory pathogens from all body sites, and their clinical significance were evaluated. RESULTS: After excluding 365 patients (230 with pulmonary tuberculosis and 135 with CAP) who were screened for inclusion but did not meet the inclusion criteria, 246 persons were enrolled in this study. Their mean age was 58.2 years old with slight male predominance (58.2%), and 171 (71%) patients had underlying illnesses. Blood cultures were performed on 191 (77.6%) patients and serologic tests on 44 (18.3%) patients. The etiologic agents were identified in 31.3%, and the list of individual agents, in decreasing order, was pulmonary tuberculosis (17 definite and 3 probable: data of six hospitals), S. pneumoniae (8 definite and 10 probable), non-pneumococcal streptococci (3 definite), aerobic gram-negative bacilli (7 definite and 4 probable), Haemophilus spp. (11 probable), mycoplasma (1 definite and 4 probable), polymicrobial infections (2 definite and 2 probable : E. coli and S. agalactiae, M. tuberculosis and S. aureus, S. pneumoniae and H. influenzae, and A. baumannii and K. pneumoniae), S. aureus (2 definite and 2 probable), and mucormycosis (1 definite). Among gram-negative bacilli, K. pneumoniae was the most common agent (8 isolates). The rates of admission to the intensive care unit and of using assisted ventilation were 18% and 9.3% respectively. The mortality was 13.8% and logistic regression analysis showed that hypothermia and tachypnea were associated with death. Hospital stay averaged 19 days. Susceptible rates of S. pneumoniae isolated from all body sites to penicillin ranged from 8% to 28% but all seven isolates from blood of patients with pneumonia were susceptible to penicillin. Also all 8 isolates of K. pneumoniae from patients with pneumonia were susceptible to cefotaxime and gentamicin. CONCLUSION: In Korea, in addition to S. pneumoniae, M. tuberculosis is an important agent causing community-acquired pneumonia. The low incidence of etiologic diagnosis is probably related to infrequent requesting of test to "atypical" pathogens and does not represent the true incidence of infections by "atypical" pathogens, which will be answered by a prospective study. The antimicrobial resistance rates of major respiratory pathogens from sterile body sites are low, however, because of a small number of the isolates this result needs confirmation by a nationwide surveillance of antimicrobial resistance.

Many neuromuscular disorders involve the heart and may produce dilated or hypertrophic cardiomyopathy. Guillain-Barre Syndrome is an inflammatory polyradiculoneuropathy in which the autonomic nervous system is sometimes involved. ST-segment and T-wave abnormalities have been reported in which the autonomic nervous system is involved, and sudden death can be attributed to fatal arrhythmic or malignant hypertension, but cardiomypathy have been reported rare. 58-year-old woman who complained of pitting edema and exertional dyspnea was admitted. Dilated cardiomyopathy was diagnosed by transthoracic echocardiography. Guillain-Barre syndrome was diagnosed by clinical manifestation, EMG, and CSF tapping. T-wave inversion in electrocardiogram was noted, and left ventricular end-diastolic diameter and ejection fraction were 69.2mm and 37.5% respectively in transthoracic echocardiography. Coronary angiograms were normal and ergonovine test was negative. Plasmapheresis has been used as mainstay of treatment in patient with Guillain-Barre syndrome. She was treated with diuretics and digoxin. Motor paralysis improved gradually by plasmapheresis and left ventricular dysfunction improved after 8 months.

BACKGROUND AND OBJECTIVES: We assessed the ability of portable echocardiography (with contrasts) to clearly delineate the cardiac structure, and evaluated the impact of its use on the diagnosis and management of critically ill patients in Korea. SUBJECTS AND METHODS: We prospectively enrolled 123 patients (mean age 66+/-16 years), who underwent portable transthoracic echocardiography (with contrast) for image enhancement at 12 medical centers. The quality of the global left ventricular (LV) images, the number of the regional LV segments visualized, the ability to visualize the LV apex and the right ventricle (RV), and any changes in the diagnostic procedure and treatment strategy were compared before and after the contrast. RESULTS: Of the 123 patients, 52 (42%) were using mechanical ventilators. The amount of poor or uninterpretable images decreased from 48% to 5% (p<0.001), after the contrast. Before the contrast, 15.6+/-1.1 of 16 LV segments were seen, which improved to 15.9+/-0.6 segments (p=0.001) after the contrast. The ability to visualize the LV apex increased from 47% to 94% (p<0.001), while the inability to clearly visualize the RV decreased from 46% to 19% (p<0.001). Changes in the diagnostic procedure (for example, not requiring other types of imaging studies) were observed in 18% of the patients, and the treatment plan (medication) was altered in 26% of patients after the contrast echocardiography. CONCLUSION: The use of a contrast agent during the portable echocardiography, in intensive care settings, can improve the image quality and impact the diagnostic procedures and treatment for Korean patients.

BACKGROUND AND OBJECTIVES: In aortic dissection (AD), CT angiography (CTA) is useful both in initial diagnosis and long term follow-up. In this study, we used CTA to evaluate the morphologic changes of aorta after AD. SUBJECTS AND METHODS: We reviewed the initial and follow-up CTA images of 43 patients with AD. The diagnoses were double-lumen dissection (n=13), intramural hematoma (n=11), and residual dissection after surgery (n=19). The duration of CTA follow-up was 3.3+/-1.9 years (range 7 - 89 months). After reviewing the CTA images of the thoracic aorta level, and of the upper and lower abdominal aorta levels, we compared the areas of total lumen, true lumen and false lumen and the area ratio of true/total lumen. RESULTS: Changes in luminal areas were greatest in the thoracic aorta, where both the true lumen area and the ratio of true/total lumen area increased. Subgroup analysis revealed that although the total lumen area increased significantly in the classic AD group, no changes were noted in the ratio of true/total lumen area. Only the increase in false lumen area (from 5.8 cm 2 to 9.0 cm 2) was significant (p=0.036). In patients with intramural hematoma, a decrease in total lumen area and an increase in the ratio of true/total lumen area were noted. CONCLUSION: In classic AD, false lumen dilatation occurs with false lumen enlargement, whereas in intramural hematoma total aorta size decreases with any increase in the ratio of true/total lumen area.
