BACKGROUND/AIMS The current study examines the expression of molecular biomarkers in hepatocellular carcinoma (HCC) and whether these findings correlate with the clinicopathologic features of the disease and patient survival. METHODS We analyzed the immunohistochemical expression of p53, mammalian target of rapamycin (mTOR), c-Met, and insulin-like growth(More)
Previous studies reported that oxaliplatin is associated with sinusoidal obstruction syndrome. However few reports on oxaliplatin induced liver fibrosis are found in the literature. Furthermore pathogenesis of liver fibrosis is not well known. We report a case of 45-yr-old Korean man in whom liver fibrosis with splenomegaly developed after 12 cycles of(More)
Ganglioneuroma (GN) of the gastroin-testinal (GI) tract is rare tumor composed of ganglion cells, nerve fibers, and supporting cells of the enteric nervous system. Diffuse ganglioneuromatosis is associated with multiple endocrine neoplasia IIB (MEN IIB), neurofibro-matosis type I (NF1, also known as von Recklinghausen disease), multiple cu-taneous or GI(More)
PURPOSE The use of abdominal computed tomography (ACT) utilization is increasing to a remarkable extent in the pediatric Emergency Department (ED), but the clinical benefit of increased use of ACT for pediatric surgical patients remains uncertain. METHODS A retrospective review was conducted to investigate if, for patients who had visited pediatric ED(More)
Adenosquamous carcinoma (ASC) is a rare tumor of the liver, which carries a poor prognosis. It has been reported mostly in the form of case studies. Recently, we experienced a case of primary ASC of the liver that has been preoperatively considered as cholangiocelluar carcinoma of the liver. Microscopically, the tumor was composed of adenocarcinoma,(More)
The most common cause of esophagorespiratory fistulas (ERFs) is associated with malignancy. The use of self-expandable metal stents is effective for the treatment of malignant ERFs, but benign ERF is rare, which is why its optimal treatment is not defined yet. There have been few reports describing benign esophagopleural fistula and its treatments in South(More)
BACKGROUND Aortic cross clamping is associated with spinal cord ischemia. This study used a rat spinal cord ischemia model to investigate the effect of distal aortic pressure on spinal cord perfusion. MATERIALS AND METHODS Male Sprague-Dawley rats (n=12) were divided into three groups. In group A (n=4), the aorta was not occluded. In groups B (n=4) and C(More)
