PURPOSE: By developing on-line statistics program to record the information of radiation oncology to share the information with internet. It is possible to supply basic reference data for administrative plans to improve radiation oncology. MATERIALS AND METHODS: The information of radiation oncology statistics had been collected by paper forms about 52 hospitals in the past. Now, we can input the data by internet web browsers. The statistics program used windows NT 4.0 operation system, Internet Information Server 4.0 (IIS4.0) as a web server and the Microsoft Access MDB. We used Structured Query Language (SQL), Visual Basic, VBScript and JAVAScript to display the statistics according to years and hospitals. RESULTS: This program shows present conditions about man power, research, therapy machines, technics, brachytherapy, clinic statistics, radiation safety management, institution, quality assurance and radioisotopes in radiation oncology department. The database consists of 38 inputs and 6 outputs windows. Statistical output windows can be increased continuously according to user's need. CONCLUSION: We have developed statistics program to process all of the data in department of radiation oncology for reference information. Users easily could input the data by internet web browsers and share the information.

BACKGROUND: Carotid intima media thickness (CIMT) and the presence of carotid plaque have been used for risk stratification of cardiovascular disease (CVD). To date, however, the association between multi-directional functional properties of carotid artery and CVD has not been fully elucidated. We sought to explore the multi-directional mechanics of the carotid artery in relation to cardiovascular risk. METHODS: Four hundred one patients who underwent carotid ultrasound were enrolled between January 2010 and April 2013. A high risk of CVD was defined as more than 20% of 10-year risk based on the Framingham risk score. Using a speckle-tracking technique, the longitudinal and radial movements were analyzed in the B-mode images. Peak longitudinal and radial displacements, strain and strain rate were also measured. Beta stiffness and elastic modulus index were calculated from the radial measurements. RESULTS: Of the overall sample, 13% (52) of patients comprised the high-risk group. In multivariate logistic regression, CIMT and elastic modulus index were independently associated with a high-risk of CVD {odds ratio (OR): 1.810 [95% confidence interval (CI) 1.249–2.622] and OR: 1.767 (95% CI: 1.177–2.652); p = 0.002, 0.006, respectively}. The combination of CIMT and elastic modulus index correlated with a high-risk of CVD more so than CIMT alone. CONCLUSION: The elastic modulus index of the carotid artery might serve as a novel surrogate marker of high-risk CVD. Measurement of the multi-directional mechanics of the carotid artery using the speckle tracking technique has potential for providing further information over conventional B-mode ultrasound for stratification of CVD risk.

Behcet's disease is multi-systemic vasculitis affecting all sizes of arteries and veins. The prevalence of coronary involvement in Behcet's disease is extremely rare. A 35-year-old woman with one-year history of Behcet's disease was in hospitalized with pseudoaneurysm of left anterior descending coronary artery, which was detected by echocardiography. The patient was successfully treated by implantation of an endovascular graft-stent.

A 40-year-old man who underwent 2 times of operation for the graft interposition with aortic valve replacement because of aortic dissection was admitted due to high fever and multiple petechiae on extremities for several days. We performed Transthoracic echocardiogram and MRI, revealed vegetation in the aortic arch and descending aorta. Re-do operation of aortic segment replacement and vegetation removal was carried out. Histological evaluation of vegetatation found fungal mass of aspergillus fumigatus.

Despite the necessity of surgical aortic valve replacement, many patients with symptomatic severe aortic stenosis (AS) cannot undergo surgery because of their severe comorbidities. In these high-risk patients, percutaneous transcatheter aortic valve implantation (TAVI) can be safely accomplished. However, no study has shown that TAVI can be performed for patients with severe AS accompanied by acute decompensated heart failure. In this case report, 1 patient presented a case of severe pulmonary hypertension with decompensated heart failure after diagnosis with severe AS, and was successfully treated via emergency TAVI. Without any invasive treatment, acute decompensated heart failure with severe pulmonary hypertension is common in patients with severe AS, and it can increase mortality rates. In conclusion, TAVI can be considered one of the treatment options for severe as presented as acute decompensated heart failure patients with pulmonary hypertension.

MELAS syndrome is characterized by mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes, and cardiac involvement also frequently occurs. A 42-year-old female was admitted because of stroke like episodes and dyspnea. She had short status and hearing difficulty, and she complainded of general weakness. Brain MR revealed cortical sweeling and edema in temporal, parietal lobe and thalamus, which was not compatibe with stroke. Echocardiography revelaed hypertrophic left ventricular myocardium, resembling hypertrophic cardiomyopathy. Endomyocardial Biopsy confirmed myocardial involvement with MELAS syndrome.

Myxoma is the most common type of primary cardiac tumor and about 75% of myxomas occur in the left atrium of the heart. Most myxomas are diagnosed by echocardiography. The growth rate of myxoma is clearly unknown and newly developed myxoma is difficult to understand clearly the onset of growth. We describe the case of a newly developed huge left atrial myxoma (7x7 cm)which showed no echocardiographic evidence of the tumor four years ago. Four years later the patient underwent transthoracic echocardiography due to preoperative evaluation that was normal. Nine months later, she presented with dyspnea. Transthoracic echocardiography showed a large mass located in left atrium. Pathology showed a myxoma that measured 7x7 cm implying a growth rate of 0.15x0.15 cm/month.
