PURPOSE: Reports of neurologic abnormalities associated with acute diarrhea are increasing recently. It was reported that the incidence of the neurologic abnormalities related to gastroenteritis was higher in rotavirus gastroenteritis than in non-rotavirus gastroenteritis. We investigated the incidence, the manifestations and the prognosis of the neurologic abnormalities associated with rotavirus diarrhea and non-rotavirus diarrhea in Korean children. METHODS: Six hundred forty-nine children who showed acute diarrhea and whose stools were examined for rotavirus were enrolled and categorized into the rotavirus positive group(n=186) and the negative group(n=463). The medical records were reviewed retrospectively for neurologic manifestations, diagnoses and the status of follow-up. RESULTS:The incidence of neurologic abnormalities in all children with diarrhea was 9.4%. Neurologic abnormalities associated with diarrhea were more common in the rotavirus positive group than in the rotavirus negative group(16.1% vs 6.7%, P=0.0002). The neurologic diagnoses of the children ranged from simple febrile convulsion to encephalitis. The rate of patients presenting neurologic abnormalities other than seizures was relatively higher in the rotavirus positive group than in the rotavirus negative group(56.7% vs 25.8%, P=0.01). All children with neurologic abnormalities showed complete recovery. CONCLUSION: The incidence of neurologic abnormalities among patients with diarrhea was about 9%. The neurologic diagnoses in patients who showed neurologic abnormalities were diversed. In rotavirus gastroenterits, the rate of patients presenting neurologic abnormalities other than seizure was higher than in non-rotavirus gastroenteritis. The outcome of the children who showed neurologic abnormalities with diarrhea was excellent.

PURPOSE: This study was undertaken to determine the differences in genotypes of rotavirus and their incidence between patients with acute rotaviral enteritis who suffered neurologic complications and those who did not suffer neurologic complications. METHODS: Among the 82 patients with rotaviral enteritis whose genotype was analyzed, 71 patients were not associated with neurologic complications(neurology(-) group), and eleven patients were associated with neurologic complications(neurology(+) group). Four G genotypes and four P genotypes were determined by reverse trans cription and multiplex polymerase chain reaction. RESULTS: In the neurology(-) group, the number of G4, G3, G2 and G1 was 24(35.3 percent), 23 (33.8 percent), 17(25.0 percent) and 4(5.6 percent), respectively and the number of P6, P4, P8 and P9 was 26(36.1 percent), 23(31.9 percent), 22(30.6 percent) and 1(1.4 percent), respectively. G2P4, and G4P6 were the most frequently found com bination genotypes, respectively. In the neurology(+) group, the number of G2, G3 and G4 was 9(75.0 percent), 2(16.7 percent) and 1(8.3 percent), respectively and the number of P4, P6, P8 and P9 was 8(66.7 percent), 2(16.7 percent), 1(8.3 percent) and 1(8.3 percent), respectively. G2P4 was the most frequently found combination genotype. The incidence of each of the G2, P4 and G2P4 was significantly higher in the neurology(+) group when compared to that of each of the G2, P4, and G2P4 in the neurology(-) group. CONCLUSION: In the patients with acute rotavirus gastroenteritis associated with neurologic complications, the G1 genotype was not found and genotypes of the G2, P4, and G2P4 were more frequently found.

BACKGROUND: Infection with respiratory virus has been shown to exacerbate asthma. However, the role of a respiratory virus in the pathogenesis of chronic asthma and/or wheezing in young children has not been clearly defined. And it also has been debated whether virus-induced wheezing in young children is an entity different from allergic asthma, or just a different expression of the same disease. In this study, we attempted to evaluate the importance of eosinophilic inflammation, comparing IL-5 and IFN-gamma levels in nasopharyngeal secretions in wheezing children with or without viral infection and the controls. METHODS: We compared IL-5 and IFN-gamma levels in nasopharyngeal secretions from 38 non-asthmatic wheezing children with viral infections (RSV in 21 children, influenza A virus in 17 children), 12 asthmatic children without viral infections and 16 children as the controls. RESULTS: The present study reported that RSV infection in children induced more releasing of IL-5 in nasopharyngeal secretions than the influenza A virus infected ones and the controls. On the other hand, the releasing of IFN-gamma levels in nasopharyngeal secretions from children with influenza A virus infection was significantly higher than those of the children with RSV infection or asthmatic children. CONCLUSION: RSV infection in children may play a role in the immune response toward a Th2 phenotype as increasing IL-5 secretion in nasopharyngeal secretion. Increased IFN-gamma production in response to the influenza A virus infection may be related to the effective Th1 responses.

We report a rare case of pulmonary artery sarcoma mimicking pulmonary artery thromboembolism in a 57-year-old man who suffered with 2-month dyspnea and exacerbated for 1 week. He was transferred from private clinic and he was diagnosed as acute pulmonary artery thromboembolism on the basis of chest CT. Chest CT, pulmonary artery angiogram, and perfusion scan were examined. We performed surgical excision with aid of CPB. The final pathologic report was that the mass was a pulmonary artery sarcoma. We experienced one case of pulmonary artery sarcoma and reported it with reference.

The surgical closure of VSD in patient with severe pulmonary hypertension has been considered a difficult problem for surgeons, because sudden hemodynamic change after closure of the defect could bring on high perioperative mortality. Recently, it was reported that UVP (unidirectional valve patch), which allows some blood to flow from right to left in case of acute right heart failure, is effective in improving the postoperative hemodynamics after closing septal defects. This 42-year old woman had suffered from VSD for 20 years and recently complained of worsening exertional dyspnea for three months, and was diagnosed of a large VSD (2.0 cm in diameter) with severe pulmonary hypertension (116/38 mm Hg), equal to systemic arterial pressure. We could successfully close VSD with severe pulmonary hypertension using one UVP and the other UVP for the creative ASD to be prepared against possible acute right heart failure. She was discharged on the fourteenth postoperative day and has been well for twelve months with spontanenous closure of UVP patch at the ninth postopeative month.

The silkworm extract powder contain 1-deoxynojirimycin (DNJ), a potent alpha-glycosidase inhibitor, has therapeutic potency against diabetes mellitus. Therefore, natural products containing DNJ from mulberry leaves and silkworm are consumed as health functional food. The present study was performed to evaluate the safety of the silkworm extract powder, a health food which containing the DNJ. The repeated toxicity studies and gentic toxicity studies of the silkworm extract powder were performed to obtain the data for new functional food approval in MFDS. The safety was evaluated by a single-dose oral toxicity study and a 90 day repeated-dose oral toxicity study in Sprague-Dawley rats. The silkworm extract powder was also evaluated for its mutagenic potential in a battery of genetic toxicity test: in vitro bacterial reverse mutation assay, in vitro chromosomal aberration test, and in vivo mouse bone marrow micronucleus assay. The results of the genetic toxicology assays were negative in all of the assays. The approximate lethal dose in single oral dose toxicity study was considered to be higher than 5000 mg/kg in rats. In the 90 day study, the dose levels were wet at 0, 500, 1000, 2000 mg/kg/day, and 10 animals/sex/dose were treated with oral gavage. The parameters that were monitored were clinical signs, body weights, food and water consumptions, ophthalmic examination, urinalysis, hematology, serum biochemistry, necropsy findings, organ weights, and histopathological examination. No adverse effects were observed after the 90 day administration of the silkworm extract powder. The No-Observed-Adverse-Effect-Level (NOAEL) of silkworm extract powder in the 90 day study was 2000 mg/kg/day in both sexes, and no target organ was identified.

Since sorafenib was introduced in 2007 for treating advanced hepatocellular carcinoma (HCC), 15 patients have achieved a complete response (CR) in advanced HCC. However, only four of these reports can be regarded as real CRs involving adequate assessments including imaging, serum tumor markers, and histologic examinations of completely resected specimens. A 54-year-old man with hepatitis C virus (HCV)-related liver cirrhosis (LC) presented to our unit. A CT scan demonstrated a 3.8-cm arterial hypervascular/portal-washout mass in the right lobe and invasion in the right portal vein. Twelve weeks after beginning sorafenib therapy, the AFP level was normalized and a CT scan showed a prominent decrease in the hepatic mass and a significant decrease in the volume of portal vein thrombosis (PVT). The patient received a right liver hemihepatectomy after 12 months. No viable tumor cells were found in the resected specimen, and there was no thrombotic obstruction of the portal vein. Twelve months later the patient showed no clinical evidence of HCC recurrence. This is the first case of CR in HCC treatment following sorafenib with histologically confirmed HCV-related HCC without LC evidence, HCC with PVT, and a follow-up of longer than 12 months. This case seems to be an extremely unusual clinical outcome in advanced HCC.
