ABSTRACT
Two distinct hantaviruses have been isolated from Apodemus agrarius in 1976 and Rattus norvegicus in 1980 in Korea. Since our serosurveys conducted in 1994, a genetically distinct hantavirus from Apodemus peninsulae has been investigated. To isolate hantavirus from A. peninsulae captured in Korea, the lung homogenate of seropositive A. peninsulae inoculted Vero E6 cells. Viral antigen was detected in a progressively higher percentage of cells with subsequent passage after 80 days postinoculation. The new isolate from seropositive Apodemus peninsulae was designated Suchong virus after Suchong valley located in northeastern region of South Korea. Comparing with hantaan virus 76-118 strain, Suchong virus-1, 2, 3 and 4 showed the similarity of 71.0~91.8% at nucleotide and 90.9~94.8% at amino acid sequences in 231 nucleotides region of M segment, and the similarity of 75.1~81.0% at nucleotide and 97.5~100% at amino acid sequences in 237 nucleotides of S segment.

A patient experienced a silent gallstone accompanied by acute severe pancreatitis during interferon theraphy for renal cell carcinoma. Although the gallstone was highly suspected to be the cause of the pancreatits, there were no duodenoscopic or endoscopic retrograde cholangiopancreatographic findings suggesting gallstone pancreatitis such as papillitis, impacted papillary and common bile duct stones, and/or a wider cystic or pancreatic duct, respectively. It is believed that the acute pancreatitis in the presenting case was probably caused by interferon because 1) sludge nor biliary crystal was not detected by light microscopic examination, 2) no tumors, anomalies, nor any obstructing ductal lesions in the pancreas were found, 3) this patient had no other potential causes of acute pancreatitis, and 4) there was no use of potential drugs which could be responsible for the acute pancreatitis other than interferon. In addition, trials of endoscopic drainage of complicated pancreatic abscesses were discussed.

Endoscopic drainage of pancreatic pseudocysts is a new nonsurgical treatment modality. Among the cystogastrostomy and stent related complications, proximal migration of stent is rare and the correction of inserted stent into a pseudocyst is very difficult. We report a correction of an incidentally inserted pigtail stent into pseudocyst using a polypectomy snare.

Swallowing caustic materials may produce full-thickness burn and loss of esophageal function. Caustics, both acid and alkalis, can corrode and destroy living tissue. Full-thickness burn of esophiageal epithelium causes severe stricture which frequently requires surgical repair. Recently, non-operative dilatation of luminal stenosis has been utilized. Esophageal endoscopic endoprosthesis has been used widely in malignant esophageal stricture but not in benign stricture. In recurrent benign esophageal stricture following repetitive balloon dilatation, we experienced a case of an 18-year-old woman with severe stricture which was successfully managed by esophageal endoprosthesia So we report this case with the review of the literature.

Recent literatures suggest that pulmonary embolus secondary to renal cell cancer may be more common than previously suspected. A 63-year-old man, who suffered a massive tumor embolism to the right main pulmonary artery after surgery for renal cell carcinoma with vena caval and renal vein invasion, was treated by emergency pulmonary embolectomy using cardiopulmonary bypass. Renal cell carcinoma occasionally extends into the inferior vena cava as a tumor thrombus. In such patients, removal of the tumor thrombus from the inferior vena cava has to be performed in addition to radical nephrectomy. However, the massive pulmonary tumor embolism is a major potential hazard during radical surgical resection. To prevent intraoperative pulmonary embolisms, scheduled use of cardiopulmonary bypass with the cooperation of cardiovascular surgeons is recommended in addition to the standard proximal vena caval occlusion technique of clipping and clamping.
