Intravenous leiomyomatosis is a rare neoplasm characterized by intravenous growth of histologically benign smooth muscle cell tumor. We report a case of intravenous leiomyomatosis with right atrial extension in a 19-year-old woman. Various surgical techniques and approaches have been previously reported. In this case, the tumor was removed with a single-stage approach via laparotomy without cardiopulmonary bypass.

Spindle cell lipoma is a relatively rare adipocytic neoplasm that is easily mistaken for a liposarcoma, and is histologically characterized by a mixture of uniform spindle cells and mature fat cells. It occurs predominantly in male patients aged 45~65 years, and in most cases it arises in the subcutaneous tissue of the neck or shoulder. We report a case of a 45-year-old woman with spindle cell lipoma arising from the left pleural cavity.

BACKGROUND: We analyzed post-operative angiography performed in symptomatic patients to evaluate the patency rates and the roles of grafts. MATERIAL AND METHOD: We reviewed 52 (15%) coronary angiograms performed for recurrent angina after prior coronary artery bypass surgery from January 1995 to June 2005. A total of 345 patients underwent coronary artery bypass surgery during this period. There were 41 men and 11 women and the mean age was 64.07+/-15.58 years. The median period from operation to re-angiogram was 68.5 months (range, 1 to 126 months). The numbers of grafts and peripheral anastomoses were 42 and 43 for internal thoracic artery (ITA), 14 and 20 for radial artery (RA), and 49 and 89 for saphenous vein. The mean number of anastomosis was 2.9 per patient. RESULT: The patency rates of ITA, RA and saphenous vein graft (SVG) were 37/43 (86%), 17/20 (85%) and 34/89 (38.2%). The patency rate of arterial grafts was significantly higher than that of SVG (p<0.001) and the patency rate of the RA was comparable to that of ITA (p=0.912). The patency rate of sequential SVGs was higher than that of single SVG (40.3% vs 31.8%, p=0.478) and the patency rate of proximal segments in sequential anastomosis was higher than that in single anastomsis (55.6% vs 31.8%, p=0.097), but statistically not significant. CONCLUSION: Arterial grafts have markedly superior patency rates than SVGs, so consideration should be given to the vigorous use of arterial grafts. The patency rate of the RA was comparable to that of ITA.

PURPOSE: We investigated the relationship between the drinking behavior of primary healthcare providers (interns and residents) and their attitude toward the screening, brief intervention, and referral to treatment (SBIRT) questionnaire used for problem-drinking patients in an emergency department and an outpatient clinic. METHODS: Our survey was sent to interns and residents in two university hospitals. The survey inquired about (1) primary healthcare providers' AUDIT (Alcohol Use Disorder Identification Test) score, (2) self diagnosis of their own drinking behavior, and (3) the attitude of problem drinking patients toward the SBIRT. We analyzed for correlations between drinking behavior and SBIRT scores. RESULTS: A total of 109 interns and residents completed the survey. The component of ratio between the normal group, risky drinking group and the alcohol use disorder group of respondents was 43.1%, 40.4% and 16.5%, respectively. The proportion of risky drinking + alcohol use disorder among our subjects was higher than in the general population. Using the AUDIT scoring method drinking behavior diagnosis and self diagnosis were correlated (p<0.05). The ratio for the normal group that disagreed for alcohol screening test's necessity (59.6%) was higher than for the risky drinking group (34.1%) and alcohol use disorder group(38.9%) (p=0.041) and shows that doctors' own drinking behavior may affect enforcement of the drinking screening test for patients. CONCLUSION: Our research suggests that alcohol use among doctors affects their attitude towards the implementation of drinking screening tests (SBIRT) for patients. Also, doctors have a higher rate of problem drinking than the general population. Those doctors in the problem-drinking group are more likely to think that they do not have any problems with their own drinking behavior and they do not agree with the necessity of a drinking screening test more than brief intervention, and referral to treatment We believe that interns and residents need medical education and self-awareness training with regards to the effects of alcohol.

This study aimed to develop and implement a progressive e-learning teaching method in the teaching of human anatomy. For analysis of the effect of new teaching methods, we made a survey of user satisfaction, content difficulty, and course management. The e-learning content was developed by the authors and implemented to class, practice, and tests, for 16 weeks. The survey was conducted on sophomores of nursing science (NS, n=42) and sports science (SS, n=26), at Kangwon National University. These two groups of students filled out a questionnaire related to effectiveness of e-learning content and tool in learning human anatomy. The results were compared between two groups. The majority of the students were satisfied with the content, difficulty level, and management of the e-learning course. Through the board of virtual classroom, all of the students played positive manners in communication and activity. Students pointed out 'reinforcement of multimedia data', 'improvement of technical service' and 'addition of broad information' as the most notable improvements of content. Therefore, we conclude that an e-learning course for undergraduate nursing science and sports science students can provide an effective learning model.

OBJECTIVE: This study aimed to construct a Korean normal elderly brain template (KNE96) using Korean elderly individuals for use in brain MRI studies and to validate it. METHODS: We used high-resolution 3.0T T1 structural MR images from 96 Korean normal elderly individuals (M/F=48/48), aged 60 years or older (M=69.5+/-6.2 years, F=70.1+/-7.0 years), for constructing the KNE96 template. The KNE96 template was validated by comparing the registration-induced deformations between the KNE96 and ICBM152 templates using different MR images from 48 Korean normal elderly individuals (M/F=24/24), aged 60 years or older (M=71.5+/-5.9 years, F=72.8+/-5.1 years). We used the magnitude of displacement vectors (mag-displacement) and log of Jacobian determinants (log-Jacobian) to quantify the deformation produced during registration process to templates. RESULTS: The mag-displacement and log-Jacobian of the registration were much smaller using the KNE96 template than with the ICBM152 template in most brain regions. There was a prominent difference in the significant averaged differences (SADs) of the mag-displacement and log-Jacobian between the KNE96 and ICBM152 at the superior, medial, and middle frontal gyrus, the lingual, inferior, middle, and superior occipital gyrus, and the caudate and thalamus. CONCLUSION: This study suggests that templates constructed from Asian populations, such as the KNE96, may be more desirable than those from Caucasian populations, like the ICBM152, in computational neuroimaging studies that measure and compare anatomical features of the frontal and occipital lobe, thalamus and caudate.

In an extremely enlarged right heart, the repeated midline sternotomy was considered to involve the risk of massive hemorrhage. A right thoracotomy provides a convenient and safe way to approach the tricuspid valve in patient who have had previous heart surgery through a midline sternotomy.
