Kawasaki disease is an acute febrile illness frequently developed in infants and children. This disease may involve coronary arteries in 15- 25% of the patients and may progress to coronary aneurysms, ischemic cardiac diseases, and sudden cardiac death. Recently we experienced successful balloon angioplasty followed by coronary stenting in a 15-year old boy with unstable angina and severe coronary arterial occlusive disease secondary to Kawasaki disease. He was diagnosed as unstable angina by 24 hours Holter monitoring, treadmill exercise stress test, echocardiography, and Dipyridamole 99mTc-sestamibi scan. And coronary angiogram revealed severe multiple stenosis and aneurysmal changes due to Kawasaki disease. We successfully performed a percutaneous transluminal coronary angioplasty with stent implantation at left circumflex arterial occlusive lesion.

Intramural hematoma(IMH) and penetrating aortic ulcer have been increasingly recognized as causes of acute aortic pathology in addition to aortic dissection. The presence of the intimal tear and a flap traversing the aortic lumen is considered to be a most reliable differential point of aortic dissection and IMH. Transesophageal echocardiography(TEE) has become a valuable modality for the diagnosis, prognosis and management of acute aortic syndrome with the unique advantages of portability and the ability to obtain high-resolution real time images. Endovascular Stent-graft placement over the primary entry tear may be an alternative to open surgery because it can close the intimal tear, which leads to thrombosis of the false lumen, excluding flow through the intimal tear and redirecting aortic flow exclusively into the true lumen. We report 88 year-old male with aortic dissection in descending thoracic aorta, successfully treated with endovascular Stent-graft implantation, which was mimicking intramural hematoma by its appearance and subclinical intimal tear diagnosed exclusively by TEE against other imaging studies.

Deregulation of G1 cyclins has been reported in several human and rodent tumors including colon cancer. To investigate the expression pattern of G1 cyclins in 1,2- dimethyl-hydrazine dihydrochloride (DMH)-induced rat colon carcinogenesis, we studied the expression of cyclin D1 and cyclin E by quantitative reverse transcription-polymerase chain reaction (RT-PCR) analysis and immunohistochemistry (IHC). The mRNA level of cyclin D1 was increased 1.2-fold in adenocarcinomas but not significantly in adenomas, when compared with normal rat colonic mucosa (p<0.05). The cyclin E mRNA level was increased 2.7-fold in adenomas and 3.3-fold in adenocarcinomas (p<0.05). The PCNA mRNA level was also increased 1.9-fold in adenomas and 1.8-fold in adenocarcinomas (p<0.05). Immunohistochemical staining revealed exclusive nuclear staining of the neoplastic cells for cyclin D1, cyclin E and PCNA. Cyclin D1 expression was detected in 56.3% of the adenomas and in 61.5% of the adenocarcinomas examined, whereas cyclin E expression was detected in 87.5% of the adenomas and in 92.3% of the adenocarcinomas. Overall, cyclin D1, cyclin E and PCNA expression was significantly increased at both the mRNA and protein levels in normal colonic mucosa, adenomas and adenocarcinomas, but there was no significant difference in the degree of expression of these genes in adenomas and adenocarcinomas. Our results indicate that the overexpression of cyclin D1 and cyclin E may play an important role during the multistage process of rat colon carcinogenesis, at a relatively early stage, and may disturb cell-cycle control in benign adenomas, and thereafter, participate in tumor progression.

PURPOSE: The urinary bladder requires an adequate energy supply to maintain contractile function. The primary metabolic fuel is glucose. Through glycolysis and oxidative phosphorylation, high energy phosphate are generated, which in turn supply the metabolic energy for the contractile activities of the urinary bladder. The aim of this study was to determine the effects of glucose deprivation and recovery from glucose deprivation on the phasic and tonic components of the contractile responses of rabbit bladder strips to field stimulation, bethanechol, and KCl. MATERIALS AND METHODS: The urinary bladder bodies of mature male New Zealand White rabbits were separated from the base above the level of the ureteral orifices, and placed in Tyrode`s solution containing glucose in 37degrees C and equilibrated with 95% O2 and 5% CO2. Bethanechol(250microM) was left in contact with the strips for 4 minutes. KCI(120 mM) was left in contact with the strips for 4 minutes. Field stimulation(31Hz, 80V, 1ms) was maintained for 2 minutes. At the end of each incubation in glucose-free medium(100 minutes for FS, 180 minutes for KCl and bethanechol), the medium was changed to Tyrode`s solution containing glucose(1mg/ml) and stimulations continued for additional 90 minutes. Changes in muscle tension were measured and recorded on a Grass model 7D polygraph. RESULTS: The results can be summarized as follow : In response to glucose deprivation, (1) the tonic responses to field stimulation, bethanechol, and KCl all decreased at a significantly greater rate than the phasic responses; (2) the phasic and tonic responses to field stimulation were both reduced to less than 10% of control within 70 minutes of glucose deprivation; (3) the tonic response to bethanechol and KCl were reduced to approximately 10% of control within 180 minutes whereas the phasic responses remained stable at 40 and 30%, respectively; and (4) glucose replacement stimulated a rapid and nearly complete recovery of the phasic and tonic components of the response to field stimulation, bethanechol, and KCl. Concolusions: These results indicate that the tonic responses to all forms of stimulation are more sensitive to glucose deprivation than phasic responses.

Angiosarcomas are rare tumors that are derived from vascular endothelial cells. They may occur in various sites, including the skin, breast, visceral organs and deep soft tissues. The pleura usually a metastatic site from angiosarcomas. However, thirty one cases of primary pleural angiosarcomas have been reported worldwide. Here, we report a 61-year-old man with a primary angiosarcoma of the pleura with a brief review of the literature.

This report is based on analysis of admissions to the department of pediatric at the Wonju Christian Hospital during the 3 3/4-year period from January 1989 to September 1993 with an Isolated ostium secundum ASD. Several methods of assessment of ASD size, namely, echographic, pulmonary-to-systemic flow ratio(Qp:Qs), and angiographic measures, were undertaken in a group of 37 patients, who were being evaluated for transcatheter closure of ASD; the results were compared with the operation diameter. The result of study was as follows : 1) The (Qp:Qs) ratio have no significant(p>0.01) correlation with the operation diameter(r= 0.342) 2) The angiographic size have a significant(p<0.01) correlation with the operation diameter (r=0.842) 3) The echo diameter has the best correlation with the operation diameter(r=0.935; p<0.01) The operation diameter can be estimated by the equation: 1.05 x echo diameter in millimeters+0.93mm. It is concluded that operation diameter of ASD can be estimated accurately by two-dimensional subcostal echo measurements, which in turn could be used for selection of device size for occlusion of the ASD.

OBJECTIVE:
In Gunsan, Jeollabuk-do, Korea, we wanted to determine if the sluggish local economy could affect citizens' health behaviors, especially mental health.
METHODS:
We divided Gunsan-si into 5 living areas and conducted Small-Area Estimations and confirmed the modified compound estimation value using the 2013-2017 Community Health Survey data and population data from Gunsan-si.
RESULTS:
The health behaviors and mental health of the residents of the western living area(Soryong-dong, Misung-dong), which is an industrial hub of Gunsan, had deteriorated or decreased compared to those of other regions.
CONCLUSIONS
Although there are limitations in analyzing the community health survey data using the small-area estimation method, it could be useful data for evaluating regional gaps and health level.

Large intestinal Lipohyperplasia (LPH) is a poorly recognized lesion characterized by adipose tissue infiltration in the submucosal layer of the colon. Most of all, LPH developed at Ileoceal valve, especially upper lip which was called by ileocecal valve syndrome. For endoscopists and radiologists, it has often remained difficult to make a distinction from malignant neoplasia. We report here the case of a mild obese, 51-year-old man who had polypoid lipohyperplasia of the colon associated with extreme hyperplasia of the appendix. His chief complaint was recurrent intermittent abdominal pain. The colonoscopic finding was a submucosal tumor-like polypoid mass originating from appendix with smooth surface, But ileocecal valve was intact. Abdominal CT finding was 2.5 cm sized round heterogeneous low density mass like lesion with intratumoral fatty density of cecal tip area with enhancement of peripheral portion. In barium enema study, after retrograde filling of contrast, smooth extrinsic indentation of cecal tip with partial filling of appendix was seen. Histological exemination revealed infiltration of mature adipose tissue in the submucosal layer. Because of recurrent abdominal pain, ileocecal resection was performed at operation. We discuss the case and review the literatures on this subject.

An aneurysm arising from the intracranial portion of the internal carotid artery(ICA) is usually found at the junction of the ophthalmic, superior hypophyseal, posterior communicating or anterior choroidal artery, or at the bifurcation of the internal carotid, but very rarely at the junction of the persistent trigeminal artery. We present a case of a 49-year-old man who presented with a massive subarachnoid hemorrhage, with large intracerebral hematoma due to rupture of the aneurysm originating from the distal portion of the internal carotid artery. During surgery, we found that the aneurysm was originated at the junction of the internal carotid artery and the artery arising from the distal to anterior choroidal artery. We considered this artery to be an anatomical variant of the uncal artery(UA) arising from the internal carotid artery.

PURPOSE: Colorectal cancer (CRC) has a high risk for postoperative thromboembolic complications such as venous thromboembolism (VTE) compared to other surgical diseases, but the relationship between VTE and CRC in Asian patients remains poorly understood. The present study examined the incidence of symptomatic VTE in Korean patients who underwent surgery for CRC. We also identified risk factors, incidence and survival rate for VTE in these patients. MATERIALS AND METHODS: The patients were identified from the CRC database treated from January 2011 to December 2012 in a single institution. These patients were classified into VTE and non-VTE groups, their demographic features were compared, and the factors which had significant effects on VTE and mortality between the two groups were analyzed. RESULTS: We analyzed retrospectively a total of 840 patients and the incidence of VTE was 3.7% (31 patients) during the follow-up period (mean, 17.2 months). Histologic subtype (mucinous adenocarcinoma) and previous history of VTE affected the incidence of VTE on multivariate analysis. There was a statistically significant difference in survival rate between the VTE and non-VTE group, but VTE wasn't the factor affecting survival rate on multivariate analysis. Comparing differences in survival rate for each pathologic stage, there was only a significant difference in stage II patients. CONCLUSION: Among CRC patients after surgery, the incidence of VTE was approximately 3% within 1 year and development of VTE wasn't a significant risk factor for death in our study but these findings are not conclusive due to our small sample size.
