The pancreatic pseudocyst as a sequela of pancreatitis or pancreatic trauma can occur at any site in the abdomen. Its detection seems to be increasing with modern imaging tools such as abdominal ultrasound or abdominal CT scanning. But recently, we experienced a case of a pseudocyst due to a ruptured pancreatic pseudocyst which was misdiagnosed as a simple hepatic cyst by abdominal ultrasonography or abdominal CT scan. A 12-year-old male presented with recurrent epigastric pain during the past 4 years. On the abdominal ultrasound and abdominal CT scan, there was an 8x7.5 cm sized sharply defined thin-walled cyst in the left lobe of the liver. First, percutaneous (cather) drainage guided by ultrasonography was done. An exploratory laparotomy was performed because of signs of hemoperitoneum. A 8x7.5 cm sized cyst was found at the left subhepatic space, which communicated with another smaller cystic lesion in the pancreatic head. Microscopic finding of the cyst showed infiltration of inflammatory cells and granulation tissue without ephithelial lined cells which is compatible to a pseudocyst. So we report this case with a review of literatures.

We report a case of primary osteosarcoma of the breast which is rare and exhibits poor prognosis. A 52 years-old-woman was admitted with rapidly growing right mammary mass. A huge lobulated dense mass with speckled calcifications, suggesting malignancy, was observed on mammography. She underwent a radical mastectomy. Grossly, the mass measured 16 14 6 cm and showed grayish white hard lobulated tissue with focal hemorrhage and necrosis. Light microscopically, the tumor was confirmed as an osteosarcoma devoid of any epithelial components. In postoperative whole body bone scan, there was no evidence of the other malignancy. To the best of our knowledge, the present case is the first report of primary osteosarcoma of the breast in Korea.

Recently MRI has been shown to be a sensitive and specific study for the noninvasive detection of meniscal tears and several MRI findings of bucket-handle meniscal tears have been reported. Therefore, the MRI findings of the menisci proven to be the bucket-handle tear with arthroscopy were evaluated and the typical MRI findings seen to be the bucket-handle meniscal tear of the knee were analysed. 76 patients with proven bucket-handle meniscal tears arthroscopically were reviewed retrospectively, in which MRI was performed in 24 patients. The 3 typical findings of bucket-handle meniscal tears were assessed: double PCL (posterior cruciate ligament) sign, flipped meniscus sign, and fragment in the intercondylar notch. In 245 cases of meniscus tears, bucket-handle meniscal tears were 76 cases (31.0%) with 52 cases at medial meniscus and 24 cases at lateral meniscus. As to clinical and physical findings of the bucket-handle meniscal tears, McMurray test, locking, joint line tenderness and giving way sense were presented in orders. The sites of bucket-handle meniscal tear were medial meniscus in 17 cases and lateral in 7 cases. The double PCL sign was seen in 10 cases (58.8%) of in medial bucket-handle meniscal tears and in 3 cases (42.9%) of 7 lateral bucket-handle meniscal tears. The flipped meniscus sign were seen in 3 cases (17.6%) of medial bucket-handle meniscal tears and in 3 cases (42.9 %) of lateral bucket-handle meniscal tears. Fragments were identified in the intercondylar notch in 8 cases (47.1%) of medial bucket-handle meniscal tears and in 3 cases (42.9%) of lateral bucket-handle meniscal tears. There were 19 cases (79.2%) in which at least one or more typical findings were presented on MR images. The MRI is a sensitive study for detection of bucket-handle meniscal tears but precise interpretation of MRI is needed for diagnosis of bucket-handle tears. In this respect, the above three typical findings are helpful and reproducible for diagnosis of bucket-handle meniscal tears with MR images; double PCL sign, fragment in the intercondylar notch and flipped meniscus sign.

The purpose of this study is to analyze the effects of IFN-r(interferon-r) on HLA-DR and ICAM-l(intercellular adhesion molecule 1) expression, a measure of cancer progression. We uses human bladder tumor cell lines of RT4(GI) and T24(GIII), a part of each type of cultured cells were treated by 200U/m IFN-r and divided into 3 groups( 24-hour, 48-hour, 72-hour) according to the time after the IFN-r treatment. Each cell was then indirectly immunofluorescence stained and analyzed using the Fluorescence Activated Cell Sorter(FACS). We founded that bladder cancer cells, when they are not treated by IFN-r, do not seem to show much HLA-DR constitutive expression. When bladder cancer cells are treated by IFN-r, the effects of IFN-r on HLA-DR expression rate seem to depend on the degree of differentiation of bladder cancer cells : well-differentiated bladder cancer cell shows higher HLA-DR expression rate when it is treated by IFN-r, while poorly-differentiated bladder cancer cell does not show much changes in HLA-DR expression rate even after it is treated by IFN-r. Bladder cancer cells of higher degree of malignancy show higher ICAM-1 constitutive expression rate and enhanced expression by IFN-r.

BACKGROUND: Stellate ganglion block (SGB) has been used to treat over 150 diseases which include diabetes mellitus and gout. This study was planned to investigate whether stellate ganglion block (SGB) could lower the levels of blood glucose, uric acid, epinephrine, and norepinephrine. METHODS: Sixty Sprague-Dawley rats within the weight of 250-350 gm were randomly devided into four groups. CS group was normal group with sham SGB with normal saline, CL group was normal group with SGB with lidocaine, DS group was diabetic group with SGB with normal saline, DL group was diabetic group with SGB with lidocaine. The diabetes was induced by intraperitoneal injection of 40 mg/kg of streptozotocin in citrate buffer (0.01 M, pH 4.5). Nondiabetic groups were given same amount of the citrate buffer. Seven days after the last injection of the streptozotocin blood glucose level was checked and more than 300 mg/dl was considered diabetic. The SGB was performed three times at right superior cervical ganglion two days apart from two days after the conformation of diabetes. Successful SGB was conformed by the ipsilateral ptosis or conjunctival congestion. Blood samplings from tail vein for the check of glucose, uric acid, and catecholamines were done before the injection of streptozotocin, seven days after the last injection of streptozotocin, and two days after the last SGB. RESULTS: The SGB with lidocaine reduced the blood glucose level only in the diabetic rats while SGB with the saline did not. The epinephrine levels were increased in the diabetics and decreased by the SGB with lidocaine without any statistical significance. Norepinephrine and uric acid levels had not been effected by the SGB and both of them had no correlationship with the glucose level. CONCLUSIONS: SGB in the diabetic rats decreases the blood glucose level. But for the effects of the SGB on the level of epinephrine further study would be needed.

The use of totally implantable central venous access devices (chemoport) has increased with the development of chemotherapeutic agents in oncologic patients, especially with no venous access site. However, there can be various complications such as port site infection, thromboembolism, injury of central vein, fracture of catheter, and migration of catheter. We report a rare case of migration of catheter to right atrium due to the separation of the catheter from the chemoport.
