Intracranial hemorrhage is the most common neuropathologic finding in premature infants. But in full-term infants, it is less common and rarely causes death. We found out intracranial hemorrhages in 21 full-term neonates by real-time neurosonography and concluded as followings. 1) Among 21 neonates, 17 infants were male and 4 infants were female. 2) In 11 (52.3%) infants the hemorrhage was detected within 7 days after birth. 3) The intracranial hemorrhage was not related with delivery type nor Apgar score. 4) In 13 cases (61.9%) the hemorrhage was in the subependymal germinal matrix and the degree was Grade I. 5) Precipitating or associated factors were asphyxia, pneumonia, ventilator care, RDS and congenital heart disease. 6) Symptoms and signs were seizure, apnea, lethargy, cyanosis, jaundice, anemia or bulging fontanel.

Human cytomegalovirus (HCMV) isolated from Korean patients is different in the antigenic and genomic structure of gB from the laboratory-adapted strain. To dissect the reactivity to HCMV glycoprotein B (gB) domains, each domain gene of gB of HCMV SNUCH1, Korean isolate, was amplified from the extracted DNA of the virus-infected fibroblasts with the specific primers by polymerase chain reaction (PCR). Amplified DNA was cloned into pcDNA3. Immunofluorescent staining and western blot analysis revealed that the expressed gB in mammalian cells was immunoreactive and equivalent to the naturally expressed gB in virus-infected fibroblasts. The antigenic component reactive with monoclonal antibodies, MCMVA 57, 88, and 98 appeared at the D3 domain of gB molecule, and that with MCMVA 66 and 135 at the D2b domain. Antibody titer was measured with HCMV-infected fibroblasts and the domains of gB expressed in mammalian cells. There was no correlation between the antibody titer to the whole HCMV and neutralizing antibody titer, and between the antibody titer to whole HCMV and whole gB. It was more reasonable to use whole gB than whole HCMV in the comparison with the neutralizing antibody titer. D3 was representative domain in gB molecule in the anti-gB reactivity. Conclusively it is highly recommendable to use the representing isolates in Korea and its domains for the detection of antibody or the analysis of antigen in the aspect of immunological properties and molecular structures.

BACKGROUND/AIMS: The efficacy of standard triple therapy (STT) in treating Helicobacter pylori infection has decreased. Many investigators have attempted to increase the eradication rate. We investigated the outcomes of concomitant therapy (CT) and STT combined with probiotics (STP) as a first-line treatment for H. pylori infection. METHODS: We reviewed the medical records of 361 patients who received either STP (n=286) or CT (n=75). The STP group received STT combined with a probiotic preparation for 1 week. The CT group received STT and metronidazole for 1 week. RESULTS: The intention-to-treat and per-protocol eradication rates were 83.6% (95% confidence interval [CI], 79.0 to 87.7) and 87.1% (95% CI, 81.2 to 89.7) in the STP group and 86.7% (95% CI, 78.7 to 93.3) and 91.4% (95% CI, 83.6 to 97.1) in the CT group (p=0.512 and p=0.324), respectively. The frequency of adverse effects was higher in the CT group (28.2%) than in the STP group (12.8%) (p=0.002). CONCLUSIONS: STP and CT are encouragingly efficacious as first-line treatments for H. pylori infection. Therefore, adding probiotics to STT may be a feasible option to avoid side effects.

BACKGROUND: QT dispersion(QTD=QTmax-QTmin) on the 12 lead ECG has been known to reflect regional variation of ventricular repolarization, and thus a marker of an increased risk of arrhythmia events. Late potential(LP) on signal averagina ECG(SAECG) is independent risk factor of ventricular arrhythmia following acute myocardial infaction(AMI). However, the relation between LP and QTD as indicator of electrophysiologic instability in AMI remains to be determined. METHOD: To determine whether there is a difference in QTD between in parients with AMI during acute phase and in normal control and whether thrombolytic therapy is assiciated with a reduction in QTD, and to determine the relationship between change of QTD and late potential on SAECG, we studied 71 patient with AMI(male 54, female 14, mean age 57yrs) and 23 controls(malw 17, female 6, mean age 58yrs). QT interval was measured on a standard 12 lead ECG in patients with AMI on admission, 2 hours after urokinase IV and 10-14 days post-AMI, and QT dispersion was calculated by difference of maximal and minimal corrected QT interval(QTmax-QTmin). A signal averaged ECG was recorded in 36 patients before discharge and coronary angiogeaphy(CAG) was performed in all patients 10-14 days post-AMI. RESULT: QTD is significantly increased in AMI compared to control(78.7+/-39.5ms vs. 24.6+/-22.3ms, P < 0.01). In patients who received thrombolytic therapy with urokinase, QTD is decreased from 75.0+/-34.4ms to 53.9+/-36.0ms(P < 0.01), whereas there is no significant change in patients who did not received thrombolytic therapy(84.8+/-47.6ms vs. 78.9+/-36.2ms, NS). There in no difference in QTD between patients with positive LP(68.4+/-23.6ms) and those with negative LP(77.8+/-32.1ms) on admission, those with positive LP(66.6+/-27.6ms) and those with negative LP(56.0+/-26.4ms) after 10-14days post-AMI. But magnitude of change of 10-14 days post-AMI QTD in patients with negative LP is larger than those with positive LP(-21.7+/-33.4ms vs. -1.8+/-15.2ms, P=0.06). CONCLUSION: QTD in acute phase of AMI is significantly reduced by the thrombolytic therapy. Patients with negative late potential tent to have greater QTD reduction within 14 days after AMI. These finding suggest that QT dispersion in patients with AMI can be reduced by early recanalization and its reduction is associated with the presence of late potential.

BACKGROUND: Dobutamine echocardiography is a useful method to detect myocardial viability in ischemic heart disease. Recently myocardial contrast echocardiography(MCE) is reported to be a new method to evaluate myocardial viability by assessing microvascular integrity of dysfunctional myocardium. We hypothesized if the microvascular integrity is maintained, the dysfunctional myocardium would improve its function by dobutamine infusion. METHOD: 10 myocardial infarction patients (acute : old=8 : 2, M : F=7 : 3, mean age=61+/-11yr) were included in the study. 2 dimensional echocardiography was performed before and during dobutamine infusion and after contrast injection to right and left coronary arteries in the catheterization laboratory. Echocardiographic analysis was done in parasternal short, apical 4 and 2 chamber views. Left ventricule was devided by 20 segments from 3 views. In each segment, will motion score(graded 1, normal, to 5, dyskinesia) before and after dobutamine infusion and opacification grade(0, 0.5, 1 denoting no, intermediate and normal opacification respectively) was compared. RESULTS: The number of segments with abnormal wall motion at baseline were 57 segments. 5 segments was exciuded due to poor image quality. Among 52 segments, 25 segments improved it's function during dobutamine infusion. Improvement of regional function was more frequent in hypokinetic segments than akinetic or dyskinetic segments (69% vs 15%). The improvement of dysfunctional regional wall motion by dobutamine infusion was observed in 80%(19/24), 67%(6/9) and 5%(1/19) of normally, intermediately and none opacified segment respectively. The correlation between wall motion score with opacification grade was 0.598 at baseline and increased to 0.766 after dobutamine infusion. CONCLUSION: In patients with myocardial infarction the dysfunctional segments but intact microvasculature assessed myocardial contrast echocardiography improves function by dobutamine infusion. These findings myocardial contrast echocardiography would be a useful method to detect myocardial viability.

PURPOSE: To assess the clinical and pathologic features of each type of intrahepatic cholangiocarcinoma,which is divided into three types according to gross appearance, and to determine the efficacy of CT in detectingthis tumor. MATERIALS AND METHODS: The pathologic and CT features of 53 surgically proven cases of intrahepaticcholangio-carcinoma were reviewed. On the basis of their gross appearance, the tumors were divided into threetypes, as follows: mass forming (n=33), periductal infiltrating (n=6), and intraductal growth type (n=14). CTscans were analyzed for sensitivity of detection and correlation between a tumors appearance and itshistopathology. RESULTS: The most common histopathologic feature of mass forming and periductal infiltrating typewas tubu-lar adenocarcinoma, while in the intraductal growth type, papillary adenocarcinoma (100%) was common.With regard to pattern of tumor spread, intrahepatic and lymph node metastasis were more common in the massforming and periductal infiltrating type than in the intraductal growth type. CT findings including intra-hepaticmass, ductal wall thickening or intraductal mass associated with segmental dilatation of intrahepataic bile ducts,corresponded with these morphologic types. CONCLUSION: This classification according to gross appearance is ofconsiderable value when interpreting the pathologic features of intrahepatic cholangiocarcinoma. CT seems to be auseful modality for the detection of tumors and may be consistent with their gross morphologic findings.
