The aortic dissection is an acute aortic syndrome, caused by an intimal tear and subsequent splitting of the media by the pulsatile blood flow. Though there would be differences in the origin of aortic dissection and therapeutic modalities, the intermediate and long-term prognoses are poor. Endovascular Stent-graft implantation is a revolutionary technique in the treatment of aortic dissection. The endovascular stent grafting in aortic dissection is less invasive and feasible method and is an effective tool for closing the entry site and promoting clot formation, reducing the size of the false lumen. Therefore, endovascular Stent-graft implantation makes possible the desirable remodelling of aorta. We report 33 year-old male with aortic dissection in the thoracic aorta, which was treated with endovascular Stent-graft implantation. Over the favorable remodelling, his dissection was healed completely by the endovascular treatment using Stent-graft.

Journal of Korean Society of Medical Informatics 2004;10(4):415-427
OBJECTIVE: This study investigates consumers' choice regarding source of health information. Specifically, the relationships between consumers' socioeconomic characteristics, health status, attitude to health, information needs and source of health information were explored. METHODS: Type of health information sources includes web-based, health professional, and mass-media types. Structured questionnaires were completed by 1,189 consumers through a telephone survey, and 622(52.3%) responses were included in analysis. RESULTS: A key finding was the significant difference for accessing health information by customer's characteristics, although the strong preference was shown in web-based resource. Accessing channels were different by consumer's needs of health information and attitude to health as well as consumer's age, job, education, and economic status. CONCLUSION: Consumer behaviors are likely to optimize physical and psychosocial health potentials through health information. Despite a growing number of available web-based health information resources, consumers continue to face a variety of barriers as they attempt to access these resources. Meeting consumer's needs for health information is an important role for all providers of health information.

OBJECTIVE: Each consumer uses different consumer evaluation by sources of health information, considering the influences of consumers' socio-demographic characteristics, health status, attitude to health, and types of health information needed. METHODS: Sources of health information include web-based resources, health professionals, and publications such as medical books, magazines, newspapers, etc. Data were collected from 1,189 respondents through a telephone survey, among whom 513(43%) responses were finally included in the analysis. The results were analysed by statistical methods including Chi-square, multiple regression, and correlation analyses. RESULTS: Key findings are as follows. First, there were significant differences in evaluation results by different sources of health information. Access to health professionals shows positive outcomes in general, followed by web-based resource. Second, the significant factors related to the access outcomes were different in each domains such as easiness, amount, understanding, reliability, and helpfulness. In addition, while access to health professionals was found to have significant influence on health behavior by improving the ability of health management, access to internet improved only the understanding of health information. CONCLUSION: Access to health professionals for health information was positively related to utilization outcomes in general, but access to publications was negatively related to outcomes. Despite the increase in the number of web-based users, they could not rely on the information they found. To effectively utilize various sources of health information and improve the nation's health by providing appropriate health information, quality assurance strategy for contents in health information websites and active intervention by health professionals should be pursued.

PURPOSE: Bone bruises of patients with acute traumatic knee injuries, that are not found on simple radiograph, can be found on magnetic resonance imaging (MRI). The purpose of this study is to evaluate the frequency and locations of bone bruises on MRI in acute traumatic anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) injury. MATERIALS AND METHODS: 25 and 19 MRls, in which acute traumatic ACL and PCL injury was pre sent and there was no abnormality in simple radiograph, were reviewed. MRI was taken within 51 days of injury. A bone bruise was determined as a geographic and nonlinear area of signal loss on T1 images and increased signal intensity on T2 images involving the subcortical bone. RESULTS: In 16 patients with bone bruises and acute ACL injury, bone bruises were found in the lateral compartment of the knee in 15 (93.8%) patients. The most common area was the lateral tibial plateau (11 cases, 68.8%) and the second was lateral femoral condyle (9 cases, 56.3%). In 5 patients with bone bruises and acute PCL injury, bone bruises were found in the lateral compartment of the knee in all 5 (100%) patients. The most common area was lateral tibial plateau (4 cases, 80%) and the second was lateral femoral condyle (2 cases, 40%). CONCLUSIONS: In patients with acute traumatic ACL or PCL injuries the bone bruises are often found on the lateral compartment of the knee, especially lateral tibial plateau and lateral femoral condyle on MRI.

BACKGROUND: Preoperative chemotherapy has been adopted in our hospital as a standard treatment for non-small cell lung cancer patients with N2 disease. However, there have been cases of pathologic N2 disease that have been detected after curative-intent surgical resection. We retrospectively studied the outcomes of initial surgical treatment without neoadjuvant therapy in patients with unexpected N2 non-small cell lung cancer. MATERIAL AND METHOD: Between January 1995 and June 2007, 225 patients were diagnosed with pathologic N2 disease after they underwent initial pulmonary resection without neoadjuvant therapy. Among them, 170 patients were preoperatively diagnosed with lymph node stage N0 or N1. We retrospectively reviewed their medical record and analyzed the outcomes. RESULT: The overall 5-year survival rate was 35.4%. The prognostic factors that were significantly associated with survival were no adjuvant therapy, histologic cell types other than adenocarcinoma or squamous cell carcinoma, a pathologic T stage more than T1, old age (> or =70 years) and no mediastinoscopic biopsy. During the follow-up, 79 patients (46.5%) experienced tumor recurrence, including loco-regional recurrence in 20 patients (25.3%) and distant metastasis in 56 (70.9%). The 5-year recurrence-free survival rate was 33.7%. CONCLUSION: Based on our findings, the survival was good for patients with unexpected N2 non-small cell lung cancer and who underwent initial pulmonary resection without neoadjuvant therapy. A prospective comparative analysis is needed to obtain more conclusive and persuasive results.

OBJECTIVE: There are few published studies which have documented psychopathological abnormalities in patients with of adolescent idiopathic scoliosis (AIS) The aim of this study was to evaluate the psychopathological influence of AIS in Korean 19-year-old males. METHODS: The authors compared the Korean military multiphasic personal inventory (KMPI) military profiles of 105 AIS cases (more than 10 degrees of Cobb's angle without surgical treatment) with the KMPI profiles of 108 normal controls. The AIS group was split depending on Cobb's angle to further evaluate this relation by the severity of AIS. RESULTS: A significantly decreased result on the faking-good response scale and an significantly increased result on the faking-bad response were observed in the AIS group compared to the control (p<0.012). The neurosis scale results, including anxiety, depression and somatization symptoms, were significantly increased in the AIS group compared to the control (p<0.010). The severity level of personality disorder and schizophrenia were also significantly increased in the AIS group (p<0.010). Differences in KMPI scale scores were not related to the severity of AIS. CONCLUSION: Young males with AIS tend to have abnormal results on the multiphasic personal inventory test compared to normal volunteers, suggesting that AIS may be related to psychopathology in the young male group in Korea. Although these psychopathology in AIS were differently observed compared to normal controls, but not interfered with military life. Clinicians are recommended to pay attention the psychopathological traits of patients with AIS.

BACKGROUND AND OBJECTIVES: Low-density lipoprotein cholesterol (LDL-C), an established cardiovascular risk factor, can be generally determined by calculation from total cholesterol, high-density lipoprotein cholesterol, and triglyceride concentrations. The aim of this study was to compare LDL-C estimations using various formulas with directly measured LDL-C in a community-based group and hospital-based group among the Korean population. SUBJECTS AND METHODS: A total of 1498 participants were classified into four groups according to triglyceride concentrations as follows: <100, 100–199, 200–299, and ≥300 mg/dL. LDL-C was calculated using the Friedewald, Chen, Vujovic, Hattori, de Cordova, and Anandaraja formulas and directly measured using a homogenous enzymatic method. Pearson's correlation coefficients, intraclass correlation coefficients (ICC), Passing & Bablok regression, and Bland-Altman plots were used to evaluate the performance of six formulas. RESULTS: The Friedewald formula had the highest accuracy (ICC=0.977; 95% confidence interval 0.974-0.979) of all the triglyceride ranges, while the Vujovic formula had the highest accuracy (ICC=0.876; 98.75% confidence interval 0.668–0.951) in people with triglycerides ≥300 mg/dL. The mean difference was the lowest for the Friedewald formula (0.5 mg/dL) and the percentage error was the lowest for the Vujovic formula (30.2%). However, underestimation of the LDL-C formulas increased with triglyceride concentrations. CONCLUSION: The accuracy of the LDL-C formulas varied considerably with differences in triglyceride concentrations. The Friedewald formula outperformed other formulas for estimating LDL-C against a direct measurement and the Vujovic formula was suitable for hypertriglyceridemic samples; it could be used as an alternative cost-effective tool to measure LDL-C when the direct measurement cannot be afforded.

PURPOSE: There is no report about psychopathological effect causing by disc herniation. The disease could impose psychopathological influence on the social life, the treatment period, and response to the treatment. This study was to evaluate retrospectively the psychopathological influence of lumbar disc herniation (LDH) among Korean 19-year-old males. MATERIALS AND METHODS: We compared the Korean military multiphasic personality inventory (KMPI) profiles of 74 LDH cases with the KMPI profiles of 150 controls. The LDH groups were categorized to 2 groups according to the presence of thecal sac compression by disc materials, and evaluated the relation between the KMPI and LDH. RESULTS: The decrease of the faking-good response scale and increase of the faking-bad response scale were observed more in the LDH group than in the normal volunteer group (p<0.05). The neurosis set such as anxiety, depression and somatization was markedly increased in the LDH group compared to the normal volunteers group (p<0.05). The scale of personality disorder was also increased more in the LDH group (p=0.002). The differences of KMPI scales were not correlated with the severe pathology of LDH. CONCLUSION: Young male with LDH may tend to have more abnormal results of multiphasic personality inventory test compared to the normal volunteers, suggesting that LDH may be related to the psychopathology in young males in Korea. Therefore, clinicians are recommended to evaluate and treat the psychopathological aspects in patients with LDH.

OBJECTIVE: To evaluate the morphometry of the anterior thalamoperforating arteries (ATPA). METHODS: A microanatomical study was performed in 79 specimens from 42 formalin-fixed adult cadaver brains. The origins of the ATPAs were divided into anterior, middle, and posterior segments according to the crowding pattern. The morphometry of the ATPAs, including the premammillary artery (PMA), were examined under a surgical microscope. RESULTS: The anterior and middle segments of the ATPAs arose at mean intervals of 1.75+/-1.62 mm and 5.86+/-2.05 mm from the internal carotid artery (ICA), and the interval between these segments was a mean of 3.17+/-1.64 mm. The posterior segment arose at a mean interval of 2.43+/-1.46 mm from the posterior cerebral artery (PCA), and the interval between the middle and posterior segments was a mean of 3.45+/-1.39 mm. The mean numbers of perforators were 2.66+/-1.19, 3.03+/-1.84, and 1.67+/-0.98 in the anterior, middle, and posterior segments, respectively. The PMA originated from the middle segment in 66% of cases. A perforator-free zone was located >2 mm from the ICA in 30.4% and >2 mm from the PCA in 67.1% of cases. CONCLUSION: Most perforators arose from the anterior and middle segments, within the anterior two-thirds of the posterior communicating artery (PCoA). The safest perforator-free zone was located closest to the PCA. These anatomical findings may be helpful to verify safety when treating lesions around the PCoA and in the interpeduncular fossa.
