Is superselective embolization of the brain AVMs, the possibilities of adjacent normal brain tissue damage necessitates preembolic evaluation. The authors performed the Sodium Amytal test on 15 patients with brain AVMs. In the AVM patients with negative Amytal test(30 cases), all patients showed normal pattern on EEG and neurologic examinations after embolization Among the five patients with positive Amytal test, three cases showed neurologic deficit and the others two didn't. In eleven patients. Repeated embolization without the Amytal test were done. Among them, 5 cases showed neurlogic deficit and the others were quite normal. In conclusion, the Amytal test is a useful method of evaluation of the risk to damage normal brain tissue which are supplied by superselected feeding vessels. Combining the EEG with this test is a sensitive and objective method in evaluating patients following the Amytal test. And it is essential to performed the Amytal test for repeat embolization procedures.

Thirty cases of lacerated canaliculi were repaired by bicanalicular silicone intubation(Pilling(R) Intubation Set)with use of a silicone sponge for nasal fixation. The results were as follows: Canalicular laceration occurred mainly in males(25 cases), and in young age group(10-39yrs). An isolated inferior canalicular laceration was the most common and occurred in 23 cases. There was no significant difference in laterality between right and left. The average follow up period was 13.8 months and final results were better in patients who were repaired earlier and had a longer intubation time. Postoperative complications occurred in 7 cases and all of them were canalicular slits. Canalicular slits were not related to the duration of intubation and did not affect the final results significantly. The advantages of this operation were good cosmetic results, minimal irritation by tube, and easy removal of tube.

Congenital diverticulum of the left ventricle is a very rare disease. Ventricular diverticulum is usually associated with other anomalies including intracardiac and midline thoracoabdominal defect. We describe a case with congenital left ventricular diverticulum presenting as an isolated lesion. A 37-year-old man presented with 4-year history of chest pain. Diverticulum was diagnosed by echocardiography and left ventriculogram.

Castleman disease rarely presents as an isolated retroperitoneal mass. We report two cases of retroperitoneal Castleman disease. Sonography showed hypoechoic mass. in two CT demonstrated homogeneously enhancing mass in two cases and calcifications in one case.

PURPOSE: This study was performed to compare the clinical characteristics of 2009 pandemic influenza A(H1N1) [A(H1N1) pdm09] and seasonal influenza A infection in the pediatric cancer patients. METHODS: A retrospective review was performed in the pediatric cancer patients who had confirmed A(H1N1)pdm09 infection at Samsung Medical Center from August 2009 to February 2010. For the comparison, the medical records of pediatric cancer patients with seasonal influenza A from January 2000 to May 2009 were reviewed retrospectively. RESULTS: Eighty-two A(H1N1)pdm09 infections were confirmed in the pediatric cancer patients. Ten patients (12.2%) developed complicated clinical course by lower respiratory infections or extrapulmonary infections; 4 pneumonia, 1 bronchitis, 1 pericarditis with pneumonia, 1 encephalitis with pneumonia, 2 meningitis and 1 pericarditis. Three patients received mechanical ventilator and ICU care. Three pediatric cancer patients (3.7%) died. The risk factors related to complicated A(H1N1)pdm09 infections were date of infection (44-45th week 2009) and nosocomial infection. When comparing with previous seasonal influenza A infections, more prompt and aggressive antiviral therapy was given in A(H1N1)pdm09 infections. CONCLUSION: The A(H1N1)pdm09 infections caused a various clinical manifestations including fatal cases in pediatric cancer patient during pandemic season. There was no significant difference in clinical course between influenza A(H1N1)pdm09 and seasonal influenza A infections except the antiviral treatment strategy.

BACKGROUND: A long-term objective is to understand the pathogenesis of neurologic injuries associated with cardiac surgery, cardiopulmonary bypass, and circulatory arrest. Our specific aims are to establish a dose of air which results in moderate to severe neurologic defects in normothermic (37degrees C) rabbits. METHODS: To first establish a dose of air which would cause unequivocal neurologic impairment, anesthetized rabbits received either 0, 50, 100 or 150 microgram l/kg of air into the internal carotid artery(n=5 in each group). One hour later, anesthesia was discontinued and animals were recovered. Animal were neurologically evaluated at 24 hours using a zero(normal) to 97(coma) point scale. RESULTS: There was a clear relationship between the dose of air injected and the severity of neurologic impairment at 24 hours, p=1.1x10(-7). Rabbits receiving 50 micrograml/kg of air were minimally affected and were difficult to distinguish from controls. In contrast, rabbits receiving 150 micrograml/kg of air were uniformly and unequivocally impaired. CONCLUSION: we recommend for future cerebral air embolism studies, 150 microgram l/kg as the optimal dose of air which would reliably produce viable subjects for 24 hours with marked unequivocal, neurologic impairment.

We report a case of a 36 year old female with coronary artery obstructive disease(Left coronary osteal stenosis), who had been admitted due to severe headache and vomitting. In admission, she was diagnosed as moyamoya disease on cerebral angiogram. She had no history of hypertension, diabetes mellitus, hyperlipidemia, smoking. She had experienced angina for 2 years, and 1 year ago she ws diagnosed as bypass surgery with left main coronary artery angioplasty. In moyamoya disease, several portions of extracranial arteries have been found to be involved, but so far, only one case has been reported the coronary involvement on coronary angiogram in the world. And, there has not been a report about moyamoya disease combined with left main osteal lesion yet. This present case indicates that we need to exam for extracranial vascular system including the heart in moyamoya disease.
