We tested correlations between anti-Helicobacter pylori IgG and IgA levels and the urease test, anti-CagA protein antibody, degree of gastritis, and age. In total, 509 children (0-15 years) were enrolled. Subjects were stratified as 0-4 years (n = 132), 5-9 years (n = 274), and 10-15 years (n = 103) and subjected to the urease test, histopathology, ELISA, and western blot using whole-cell lysates of H. pylori strain 51. The positivity rate in the urease test (P = 0.003), the degree of chronic gastritis (P = 0.021), and H. pylori infiltration (P < 0.001) increased with age. The median titer for anti-H. pylori IgG was 732.5 IU/mL at 0-4 years, 689.0 IU/mL at 5-9 years, and 966.0 IU/mL at 10-15 years (P < 0.001); the median titer for anti-H. pylori IgA was 61.0 IU/mL at 0-4 years, 63.5 IU/mL at 5-9 years, and 75.0 IU/mL at 10-15 years (P < 0.001). The CagA-positivity rate was 26.5% at 0-4 years, 36.5% at 5-9 years, and 46.6% at 10-15 years for IgG (P = 0.036), and 11.3% at 0-4 years, 18.6% at 5-9 years, and 23.3% at 10-15 years for IgA (P < 0.001). Anti-H. pylori IgG and IgA titers increased with the urease test grade, chronic gastritis degree, active gastritis, and H. pylori infiltration. Presence of CagA-positivity is well correlated with a high urease test grade and high anti-H. pylori IgG/IgA levels.

Although heart transplantation is a final therapeutic option in pediatric patients with dilated cardiomyopathy (DCMP), the shortage of pediatric heart donors is a major obstacle. In adults with DCMP characterized by cardiac dyssynchrony, cardiac resynchronization therapy (CRT) is known to be an effective treatment option. However, there is a lack of evidence on the effectiveness of CRT in infants with DCMP. Several studies have reported improvement in hemodynamics and cardiac performance following CRT in infants with DCMP. Here, we report CRT in an infant with DCMP during extracorporeal membrane oxygenation with 5 months of follow-up.

BACKGROUND: The patients with traumatic brain injury showed ischemia due to increased intracranial pressure. This study evaluated the relationship of pre-anesthetic serum lactate level with in-hospital mortality. METHODS: The archived medical records of 121 patients were retrospectively reviewed. Demographics and preoperative serum lactate level were analyzed. RESULTS: Of the 121 patients, 32 patients expired in the hospital after decompressive craniectomy. Preoperative serum lactate levels were 3.2 +/- 2.2 mmol/L in the survivors and 5.4 +/- 3.0 mmol/L in the dead (P = 0.001), and the receiver operating characteristic curve revealed that a cut off value of 3.60 mmol/L was reasonable for predicting mortality. CONCLUSIONS: Preoperative serum lactate level is highly correlated with in-hospital mortality after decompressive craniectomy in traumatic brain injury.

PURPOSE: Brain natriuretic peptide (BNP) has been considered a biochemical marker for myocarditis in Kawasaki disease. We performed this study to determine its quantitative significance. METHODS: We attempted to correlate log-transformed BNP concentrations (log-BNP) and clinical, laboratory, and echocardiographic variables in 81 children with Kawasaki disease. Stepwise multiple linear regression analysis was used to determine the variables independently associated with log-BNP concentration. RESULTS: Serum C-reactive protein level (P<0.0001), serum alanine aminotransferase concentration (P=0.0032), white blood cell count (P=0.0030), and left ventricular mass index (P=0.0024) were positively related with log-BNP, and hemoglobin level (P<0.0001), serum albumin level (P<0.0001), Na+ concentrations (P<0.0001), left ventricular fractional shortening (P=0.0080), and peak early diastolic tissue velocity of the left ventricular basal lateral segment (P=0.0045) were negatively related to the log-BNP concentration. Multiple regression analysis showed that serum albumin concentration (R2=0.31, P=0.0098) and left ventricular mass index (R2=0.09, P=0.0004) were significantly associated with the log-BNP concentration. CONCLUSION: Elevated BNP levels during the acute phase of Kawasaki disease may be attributable to cardiac dysfunction associated with the increase in left ventricular mass, and log-BNP concentration may be a quantitative biochemical marker of myocarditis in Kawasaki disease.

BACKGROUND AND PURPOSE: There is recent evidence of various types of morphological changes in the hippocampus of a rodent model of medial temporal lobe epilepsy (mTLE). However, little is known about such changes in humans. We examined the histological changes [i.e., neuronal loss, cell genesis, and granule cell dispersion (GCD)] in surgical hippocampal specimens taken from patients with mTLE. METHODS: Nissl staining, and nestin and Prox1 immunohistochemistry were performed on human hippocampal specimens obtained from patients with medically intractable mTLE, thus allowing the analysis of neuronal loss, cell genesis, and GCD, respectively. We also assessed the correlations between clinical parameters and the histopathologic findings. RESULTS: The degree of cell genesis in the granule cell layer was significantly correlated with the severity of GCD, history of childhood febrile seizures, and frequent generalized seizures. Cell genesis was not correlated with cell death, age at seizure onset, duration of epilepsy, or the mean frequency of all seizures. CONCLUSIONS: Our results indicate that cell genesis in the dentate gyrus of patients with mTLE is associated with GCD and is influenced by the presence of febrile seizures during childhood and the frequency of episodes of generalized seizures.

BACKGROUND AND PURPOSE: We performed this study to explore the various diagnostic roles of video-EEG monitoring (VEM) and to assess the outcome after VEM. METHODS: 1749 patients who underwent VEM in the adult epilepsy section were included. We classified purposes of VEM and assessed outcome after VEM or epilepsy surgery guided by VEM. The outcome was assessed according to seizure frequency during the previous 12 months from the day of follow-up evaluation. RESULTS: The purposes of VEM were presurgical evaluation (68.5%), confirmation of epilepsy (15%), classification of seizures (9.4%), diagnosis of pseudoseizures (5.5%), and detection of nonconvulsive status epilepticus (1.7%). The efficiency of VEM was 89.2%, highest for presurgical evaluation (97.1%) and lowest for confirmation of seizures (66.0%). The number of events detected and the number of days needed differed according to the purposes of VEM. Epilepsy surgery was performed in 629 patients. The outcome of patients with epilepsy surgery was significantly better compared with patients without surgery despite presurgical evaluation (p<0.0001). Various other illnesses with transient symptoms as well as various epileptic syndromes were diagnosed by VEM. Better outcomes were observed in patients in whom VEM was used for classification and confirmation of seizures compared with patients in whom VEM was used for presurgical evaluation. CONCLUSIONS: VEM is a useful tool for various purposes. The efficiency, number of events and days of VEM differed according to the purposes. Patient outcome was also dependent on the purpose of the VEM as well as on treatment modalities.

Ectopic pancreas rarely produces clinical symptoms. Most commonly reported symptoms were abdominal pain, epigastric discomfort, nausea, vomiting, and bleeding. However, presentation of specific symptoms due to its size and location, including obstructive jaundice, and pyloric obstruction are possible. Ectopic pancreas is subject to various pathological changes occurring in the pancreas itself; namely, cyst, pancreatitis, hemorrhage, necrosis, and neoplastic change. We present a case of 60-year old woman with right upper quadrant pain in whom the surgical pathologic diagnosis was ectopic pancreas of the stomach complicated by pancreatitis and pseudocyst formation.

BACKGROUND: The current techniques for percutaneous coronary interventions (PCI) remain limited by restenosis. Recent studies have provided evidence of inflammation playing a role in the pathogenesis of cardiovascular disease. METHODS: Whether inflammatory markers are predictors of subsequent restenosis were prospectively tested in 272 consecutive patients with angiographically proven coronary artery disease. Patients having undergone PCI at Chonnam National University Hospital, between Sept. 1999 and Mar. 2001, were divided into two groups according to the occurrence of restenosis on a follow-up coronary angiogram: Group I were patients with restenosis (n=99, 59.5 +/- 10.8 years, M: F=77: 22) and Group II were those without restenosis (n=173, 58.8 +/- 10.2 years, M: F=131: 42). The IgG seropositivity, cytomegalovirus (CMV) titers, C. pneumoniae, H. pylori and levels of C-reactive protein (CRP) were compared between the two groups. RESULTS: There were no statistical differences in the seropositivity of the CMV IgG C. pneumoniae IgG and H. pylori IgG between the two groups (Groups I vs. II: 100 vs. 100%, 24.7 vs. 25.7% and 62.2 vs. 63.7%, respectively). Of the angiographic parameters, a low Thrombolysis In Myocardial Infarction (TIMI) flow (TIMI 0 or I) was more common in Group I than Group II (p=0.038). The patients with an elevated CRP (> 0.5 mg/dL) were more common in Group I than Group II (57.6 vs. 36.4%, p=0.001), with the CRP values being higher in Group I than Group II (3.3 +/- 5.8 vs. 1.3 +/- 2.6 mg/dL, p=0.001). According to a multiple logistic regression analysis, the CRP was the only predictor of restenosis, with an odds ratio of 2.1169 (95% C.I. 1.2062-3.7154, p=0.009). CONCLUSION: The CRP value is the most important predictor of restenosis after PCI.

BACKGROUND AND OBJECTIVES: Despite marked advances in the design of percutaneous coronary intervention hardware, total occlusion remains associated with a low primary success rate. The most common cause of failure is the inability to cross the lesion with a guidewire. We report the results of a non-randomized single-center investigation using a hydrophilic coated guidewire (Crosswire NT). SUBJECTS AND METHODS: We analyzed the angiographic results of 92 patients (68 males, 24 females, age 58.8+/-9.7 years-old) who underwent angioplasty utilizing Crosswire NT for either total (TIMI flow 1) or subtotal occlusion at Chonnam National University Hospital between December 2000 and July 2001. RESULTS: Clinical diagnoses of the studied subjects revealed 40 cases of acute myocardial infarction, 15 of myocardial infarction, 29 of unstable angina and 8 of stable angina. The primary success rate was 79.3% (73/92), the success rate in total occlusion was 69.0% (40/58), and that of the chronic total occlusion cases among the total occlusion group was 64.3% (18/28). The success rates in the use of Crosswire NT as the first and second choice were 85.7% and 78.8%, respectively. The abrupt occlusive lesions, complex lesions more than type B 2, and presence of collateral circulation were all associated with a lower success rate. Coronary artery perforation occurred in one case. CONCLUSION: The new nitinol hydrophilic wire, Crosswire NT, is a safe and effective tool for the recanalization of total occlusive coronary lesion.

BACKGROUND AND OBJECTIVES: It has been reported that intracoronary radiation therapy (ICRT) using a Ho-166 coated balloon inhibits restenosis of porcine coronary arteries. However, the consequences of ICRT on coronary artery endothelial function are unknown. The aim of this study is to investigate the effects of ICRT using a Ho-166 balloon on coronary artery endothelial function and vasomotor reactivity. MATERIALS AND METHODS: Female pigs (25-35 kg) were orally premedicated daily with aspirin (100 mg) and ticlopidine (250 mg) for the duration of the study. Under sterile conditions with local anesthesia of the skin provided by 2% lidocaine, an arteriotomy of the left carotid artery was performed, an 8 Fr sheath was inserted, and intraarterial heparin sodium (10,000 IU) was injected. Under fluoroscopic guidance, the coronary artery main branch was selected through an 8 Fr guiding catheter for coronary artery overdilation injury (balloon to artery ratio, 1.3:1) and ICRT. A Ho-166 coated balloon prepared to deliver 20 Gy at a depth of 2 mm from the balloon surface was used for ICRT. The coronary artery main branch in each pig was randomly assigned to either balloon injury (Group I) or balloon injury plus ICRT (Group II). Coronary artery segments were taken from the animals at 0 week (n=8), 4 weeks (n=6) and 8 weeks (n=8) after the intervention. Data in each group denote the relative ratio compared to non-injured coronary artery and are expressed as mean +/- standard error of mean. RESULTS: The degree of KCl-induced contractile response (g) was not different between the two groups at 0 and 4 weeks, but was significantly decreased in group II compared to group I at 8 weeks (I:1.04+/-0.06, II:0.79+/-0.07, p=0.014). In rings precontracted with prostaglandin F 2alpha (PGF 2alpha), the degree of NO-dependent relaxation (%) induced with substance P was significantly decreased in group II compared to group I at 0 week (I:0.93+/-0.33, II:0.47+/-0.31, p=0.03), but the difference between the two groups was not significant at 4 and 8 weeks. In rings precontracted with PGF 2alpha and LAME in the presence of indomethacin, the degree of EDHF-induced relaxation (%) using substance P was not different between the two groups at 0, 4 and 8 weeks; nor was the degree of sodium nitroprusside-induced endothelium independent relaxation (%) in depolarized conditions with PGF 2alpha. CONCLUSION: Endothelial function of the porcine coronary artery is only transiently impaired after ICRT using a Ho-166 coated balloon. Therefore this therapy can be used as an effective method to prevent restenosis after percutaneous coronary intervention.
