Multilocular cystic renal cell carcinoma is a distinct subtype of renal cell carcinoma with its pathological characteristics and good prognosis. Multilocular renal cysts and renal cell carcinoma with cystic change are important differential diagnoses. We report a case of multilocular cystic renal cell carcinoma in a 37-year-old woman who came to the hospital because of the right renal mass. The removed right kidney showed a 6x4 cm well defined cystic mass in the lower pole. On cut section there were multiple cavities in the mass, filled with serosanguineous fluid and focal yellowish solid area. Microscopically, these cysts were lined by a single layer of flat or cuboidal cells consisted of clear cytoplasm with small central nuclei. In some portions of the tumor, the clear neoplastic cells formed sheets within the septa or walls of the cysts.

A valid assessment of obesity in children and adolescents is important due to significant change in body composition during growth. This study aimed to develop percentile curves of body fat and fat free mass using the Lambda, Mu, and Sigma method, and to examine the relationship among body mass index (BMI), fat mass and fat free mass in Korean children and adolescents, using the Korea National Health and Nutrition Examination Survey (KNHANES) 2009-2010. The study subjects were 834 for boys and 745 for girls aged between 10 and 18 yr. Fat mass and fat free mass were measured by dual-energy x-ray absorptiometry. The patterns of development in body fat percentage, fat mass and fat free mass differed for boys and girls, showing a decreased fat mass with an increased fat free mass in boys but gradual increases with age in girls. The considerable proportion of boys and girls with relatively normal fat mass appeared to be misclassified to be at risk of overweight based on the BMI criteria. Therefore, the information on the percentiles of body fat and fat free mass with their patterns would be helpful to complement assessment of overweight and obesity based on BMI for Korean children and adolescents.

In this study, the α-amylase inhibitory activity, α-glucosidase inhibitory activity, pancreatic lipase inhibitory activity, and Xanthine Oxidase inhibitory activity of the fruiting body extracts of 5 varieties of Agaricus bisporus (AB) were confirmed. First, the α-amylase inhibitory activity of AB12, AB13, AB18, AB34, and AB40 methanol extracts was lower than that of acarbose, a positive control, in all concentration ranges. The α-glucosidase inhibitory activity of the AB40, AB13, and AB12 methanol extracts at the extract concentration of 1.0 mg/mL was 80.5%, 81.3%, and 78.5%, respectively, similar to that of acarbose, a positive control. The pancreatic lipase inhibitory activity of the methanol extract of Agaricus bisporus fruiting body was significantly lower than that of the positive control orlistat in the concentration range of 50 $ 1.000 (mg/mL). The Xanthine Oxidase inhibitory activity was 0.5 $ 8.0 mg/mL of each extract, which was significantly lower than that of the positive control allopurinol in the same concentration range. However, the Xanthine Oxidase inhibitory activity of AB13 and AB40 at 8.0 mg/mL was about 70%, which was higher than that of other mushrooms. In conclusion, five kinds of Agaricus bisporus fruiting bodies seem to have inhibitory effects on enzymes such as α-amylase, α-glucosidase, pancreatic lipase, and Xanthine Oxidase that degrade starch and protein. In particular, it has an inhibitory effect and a reduction effect on xanthine oxidase that causes gout, so it is expected that it can be developed and used as a food or health supplement with health functional properties through future research.

Among the 98 patients who underwent operations for thoracolumbar spinal lesions from May 1989 to September 1994, the authors performed clinical analysis of 72 patients who were followed-up for more than 12 months. There were 52 cases of trauma, 18 cases of tuberculous spondylitis, and 2 cases of metastatic tumor. After partial or toal vertebrectomy, interbody fusion was performed using autogenous iliac bone or autogenous ribs which were taken while approaching the thoracic spine, and stabilized using Kaneda devices. Complete neural decompression was possible under direct vision in all cases. Neurologic deficits improved to an average of 1.7 grades using a modified Frankel scale. Patients with tuberculous spondylitis did not show recurrence or any evidence of increased risk of secondary infection caused by instrumentation. Loosening or breakdown of instruments occurred in 4 patients, and spinal deformity in 7 patients, but reoperation was not needed in any of these patients. By anterior decompression, interbody fusion and stabilization using Kaneda device in thoracolumbar spinal lesions, we could obtain satisfactory neurologic improvement as well as immediate firm stability and high fusion rate involving only a minimum(usually two) number of motion segments as compared with the posterior approach.

Pulmonary epithelioid hemangioendothelioma (PEH) is a rare tumor that occurs among young women and typically presents as bilateral multiple nodules. In the present report, we describe an uncommon case of PEH presented as a single cavitary nodule in a 33-yr-old asymptomatic man. This is the first case of PEH presented as a single cavitary nodule in the English literature. Three years of the follow-up without treatment was performed. Overall histologic findings were accord with conventional PEH, but some atypical features such as, increased mitotic activity (mean; two per ten high power fields), necrosis, spindling, and pleural and vascular invasion were recognized. Immunohistochemically, the tumor cells were positive for CD34. This report may contribute to the data on clinical findings and natural history of this rare tumor.

BACKGROUND/AIMS: Obstructive jaundice is developed from the cholangiocarcinoma, biiliary tract stone, biliary benign stricture and pancreatic head cancer and is rapidly progress to cholangitis or sepsis. So early decompression, accurate diagnosis and treatment are very important. Percutaneous transhepatic choledocoscopy (PTCS) and endoscopic retrograde choledocoscopy (ERCS) have been used for evaluation of the obstructive jaundice. We performed, through the PTCS, electrohydraulic lithotripsy (EHL) for biliary tract stone rernoval, biopsy for diagnosis of biliary stric and self expandible metalic coil stent (EndocoilTM stent, Instent Co.) insertion on biliary stricture to evaluate the usefullness of PTCS in patients with obstructive jaundice. METHODS: Between Auguest 1994 and September 1995, PTCS was performed in 37 patients with obstructive jaundice. First, percutaneous transhepatic biliary drainage (PTBD) with 7Fr. drainage tube was done. Three days later, we exchainged the 7Fr. drainage tube with 16Fr.. Seven days later, through the PTCS, we performed EHL, biopsy and EndocoilTM stent insertion.
