Mucocuaneous Lymph Node Syndrome(Kawasaki disease) is a new diseae entity that was first described by Kawasakiin 1967. It occures predominantly in children less than 5yrs old and acute febrile illness, which is mucocutaneousinvolvment associated with swelling of cervical lymph nodes. The coronary artery aneurysms have been revealed 20–30% of patients with Kawsaki disease. The authors report a case of multiple coronary artery aneurysms inKawasaki disease which was diagnosed by a coronary arteriography.

PURPOSE: This study was performed to investigate the relationship between serum vitamin D and parathyroid hormone (PTH) levels as well as to describe the prevalence and the risk factors of vitamin D deficiency (VDD) in Korean children. METHODS: Participants were 1,212 children aged 4 to 15 years, who visited Bundang CHA Medical Center (located at 37degreesN) between March 2012 and February 2013. Overweight was defined as body mass index> or =85th percentile. Participants were divided into 4 age groups and 2 seasonal groups. VDD was defined by serum 25-hydroxyvitamin D (25OHD) <20 ng/mL. RESULTS: The level of 25OHD was significantly lower in overweight group than in normal weight group (17.1+/-5.1 ng/mL vs. 19.1+/-6.1 ng/mL, P<0.001). Winter-spring season (odds ratio [OR], 4.46; 95% confidence interval [CI], 3.45-5.77), older age group (OR, 1.60; 95% CI, 1.36-1.88), and overweight (OR, 2.21; 95% CI, 1.62-3.01) were independently related with VDD. The PTH levels were significantly higher in VDD group compared to vitamin D insufficiency and sufficiency group (P<0.001). In normal weight children, 25OHD (beta=-0.007, P<0.001) and ionized calcium (beta=-0.594, P=0.007) were independently related with PTH, however, these associations were not significant in overweight children. CONCLUSION: VDD is very common in Korean children and its prevalence increases in winter-spring season, in overweight children and in older age groups. Further investigation on the vitamin D and PTH metabolism according to adiposity is required.

The present study was performed to evaluate the effect of Tetracycline-HCl and Saline on the change of implant surface microstructure and surface roughness according to application time. Implants with resorbable blasting media surface were utilized. Before test all 13 implants were measured surface roughness. Among them, 6 implants were rubbed with 50mg/ml Tetracycline-HCl solution and other 6 implants with saline for 1/2min., 1min., 1 1/2min., 2min., 2 1/2min and 3min. Then, specimens were processed for scanning electron microscopic observation and surface roughness after test. The results of this study were as follows. 1. Control group showed a few irregular, rough, uneven surface with crater-like depression. 2. The test group with Tetracycline-HCl conditioning showed an altered surface when Tetracycline-HCl was applied for 30secs, and showed a various surface alteration as application times go on. 3. The test group with Saline conditioning showed no significant surface differences and surface roughness. 4. The significant increase of Ra value was showed when Tetracycline-HCl was applied for 30secs. In conclusion, the 50mg/ml Tetracycline-HCl must not be applied for the RBM surface implant for surface treatment.

About one tenth of all CNS neoplasms involves the brain. Due to their location in the ventricles they often present similar nonspecific clinical manifestation. Localization and differential diagnosis are dependent on radiological investigation. For the identification of specific CT characteristics of the intraventricular tumors and the differental diagnosis, we retrospectively analyzed 22 pathologically proved cases seen on CT. Important differential features included age and sex of the patient, the location within the ventricle, and the morpholgic appearance of the mass and density on CT before and after intravenous administration of contrast material. Meningiomas (4 cases) and a germinoma showed increased density on the precontrast CT scans, and demonstrated dense uniform enhancement of the postenhanced scan. Choroid plexus papillomas (3 cases) showed dense uniform contrast enhancement. Intraventricular neurocytomas (3 cases) demonstrated characteristic attachment to the septum pellucidum, confinement of the lateral and third ventricle, and calcification within the mass Colloid cysts (2 cases) showed characteristic location of anterosuperior aspect of the third ventricle. In conclusion, CT findings of intraventricular tumors are usually nonspecific. The location of the mass and the patient's age are the most helpful information in the differential diagnosis.

Recently, new trials for the treatment of the vesicoureteral reflux have been proposed. These trials convince us of the need to reevaluate the ureterovesical junction and to reinvestigate the role of the detrusor muscle and the ureteral sheath. We studied forty adult and five infant human bladders and distal ureters. Microscopic sections were studied, taken serially from the ureterovesical junction and adjacent urinary bladder with the hematoxylin-eosin and the Gomori trichrome staining method. The slit shaped ureteral orifice was most commonly observed ( 57.0 %). The approximate ratio of the submucosal length to the intramural ureter was 2:3. Ureteral sheath consists of smooth muscle fibers (bundles) arranged in a helical fashion and loose connective tissues which envelope the distal ureter over a 3 cm distance to the juxtavesical portion. These structures are independent from the ureter proper. The muscle bundles of ureteral sheath are of 4 types: 1. Those which extend from the outer bladder wall to the juxtavesical ureters (JVU) and, 2. continuing from JVU, these become the detrusor muscle after entering the bladder. 3. Bundles run from the JVU to the trigone, and 4. bundles run to the trigone from the mid-circular layer of the detrusor muscle. In the bladder, most roof muscle bundles of ureteral sheath run to the upper portion of the trigone after crossing the intramural ureter ventrally. Most floor bundles run to the inferolateral portion of the bladder. In infants, the deep trigone and basal detrusor muscle are relatively thicker and not compactly organized. We conclude that ureteral sheath is of detrusor muscle origin. We suggest that ureteral sheath functions as a part of a preventive mechanism with compressing the intravesical ureter by contraction in voiding and filling phase independently against vesicoureteral reflux.

PURPOSE: To evaluate the specif!c radiologic findings of the dysgenesis of corpus callosum(CCD) on CT and/or MR images. MATERIALS AND METHODS: The authors reviewed retrospectively CT and/or MR images of 10 patients with CCD. After classifying CCD into partial and total type according to the degree of its development, we investigated structural abnormalities on CT and/or MR images resulting from or related to CCD and then associated anomaly. RESULTS: The most common findings of CCD on axial planes of CT and/or MR images were dilatation of posterior part of the lateral ventricles(8/10) and feature of the bodies of the both lateral ventricles(8/10) in parallel. Sagittal and coronal planes of MR demonstrated exact extent of dysgenesis of the corpus callosum(5/5) and radiating pattern of gyri in medial surface of cerebral hemisphere extending to the 3rd ventricle without interruption by cingulate sulcus(4/5). CONCLUSION:MR image of mid-sagittal plane appeared most useful in diagnosis of CCD because of its direct depiction of the whole length of corpus callosum. In most cases, however, CCD can be easily diagnosed with CT scan by characteristic findings of dilatation of the posterior part of lateral ventricles and paralleling of the lateral ventricles.

A 77-year-old woman was admitted to this hospital for evaluation of chest pain for 3 days. On physical examination, icteric sclerae, inspiratory crackles on both lower lung field and normal heart sounds were observed. Electrocardiograms showed pathologic Q waves with ST elevations in the precordial leads(V1-V4). Chest X-rays showed mild pulmonary edema with anteroseptal wall akinesia. Cardiac enzyme studies were compatible with AMI. Hematologic investigation revealed severe thrombocytopenia and microangiopathic hemolytic anemia. Coagulation profiles were normal. Coombs test, sucrose lysis test, anti-platelet antibody and antinuclear antibody were all negative. Urinalysis showed albuminuria(+++) and microscopic hematuria. Initial therapy with aspirin, nitrate, morphine and prednisolone was started. Ten hours after admission, she developed agitation, aphagia and confusion with progression to coma. Computed tomography of the brain was normal. Five units of fresh frozen plasma were infused. After one day, platelet counts slightly increased. But cardiogenic shock ensued and she died despite cardiopulmonary resuscitation. AMI has not been reported in association with TTP. This patient had no risk factors for coronary artery disease and no previous history of angina. TTP was clinically diagnosed with confidence by excluding other known cause of microangiopathic hemolytic anemia with thrombocytopenia. Coronary angiogram and bone marrow examination could not be performed due to a rapidly fatal course. The etiology of AMI in this patient was not confirmed, but clinical evidence strongly supported etiologic association with TTP.

PURPOSE: To evaluate the hemodynamic change by portal tumor thrombus in hepatocellular carcinoma(HCC). MATERIALS AND METHODS: We reviewed 35 cases of combined spiral CTHA and CTAP in 25 HCC patients with portal tumorthrombus from April 1993 to October 1994, regarding to portal tumor thrombus, the involved area of arterioportal(AP) shunt and the development of cavernous transformation of portal vein, in comparison with hepaticand superior mesenteric arteriography. RESULTS: Spiral CTHA showed hyperattenuating tumor, portal tumor thrombus and hyperattenuating peritumoral parenchymal area. Spiral CTAP showed perfusion defect area including tumor, portal tumor thrombus and peritumoral area distal to portal vein obstruction. In 15 cases, portal tumor thrombus showed intraluminal and marginal hyperattenuating linear structures on CTHA due to transvasal AP shunt and tumor feeding arteries, which were corresponding to thread and streaks sign on hepatic arteriography. Cavernous transformation of portal vein was demonstrated in 15 cases as irregular periportal hyperattenuating collateral vessels on spiral CTAP. In 32 cases, portal vein was visualized on CTHA due to AP shunt. And according to shunt amount, we classified AP shunt into 4 grades. Grade I means only the presence of portal tumor thrombus without AP shunt, grade II with segmental AP shunt, grade III with one lobar AP shunt, and grade IV with both lobar AP shuntor the presence of cavernous transformation of portal vein. Grade I was seen in 3, grade II in 4, grade III in 13 and grade IV in 15 cases. CONCLUSION: Variable CTHA and CTAP findings were shown in HCC patients with portal tumor thrombus according to the amount of AP shunt and the presence of cavernous transformation of portal vein. Combined CTHA and CTAP are useful to differentiate the tumor thrombus from simple thrombus and are very sensitive method for detecting AP shunt. Understanding these findings related with portal tumor thrombus is important topredict patient}s prognosis and to decide treatment method.
