Endoscopic retrograde biliary drainge is a useful method of palliative treatment of malignant biliary obstruction with respect to safety, rapidity in decompression of obstruction. However, despite of efforts to prolong patency of the stents, the main long term complication of current-widely used plastic endoprosthesis is to tendency for the stents to become clogged by sludge leading to recurrent jaundice and cholangitis, finally, obstruction of stents. Recently, in an effort to improve the patency of stent, variety of self-expandable metallic endoprosthesis have developed and which can be compressed into and inserted through small lumen catheter with large-bored lumen in expandable state. However, most of these open mesh of self-expandable stents allows tumor in growth which causes reobstruction, and additionally it is nearly impossible to retrieve the inserted prosthesis. Recently developed coil metal stent(Endocoil, Intent Co.), which, unlikely other previous metallic stent, has possibility of retrieving prosthesis and prevention of tumor ingrowth. We experienced a case of 52-year old male sufferd from malignant biliary obstruction due to recurrence of cancer at peripancreatic lymph nodes and combined with common bile duct stones on both proximal and distal side of the stricture, in whom Endocoil was implanted with sucessful decompression of obstruction and simultaneous removal of biliary stones located at both side of stricture.

PURPOSE: This study was explored the experiences of the middle-aged women and tried to understand their lived experiences. METHOD: The data was collected from 9 participants living in Seoul from Sep. to Dec. 2003. Collection of data was by means of in-depth interviews. The analysis of the data was made the phenomenological analytic method suggested by Colaizzi(1978). RESULT: The 10 themes were extracted in this study ; sense of emptiness, repentance of one's past, decline of physical functions, lost one's youth, worry of children, thinking about future, importance of husband, importance of job, composure of mind, content with present life. CONCLUSION: Therefore, the helpful program should be developed and applied to extend positive lived experiences, and relieve or exclude negative lived experiences for the middle aged women.

In order to assess the effects of radiofrequency-induced local hyperthermia on the normal liver, histopathologic findings and biochemical changes after localized hyperthemia in canine liver were studied. Hyperthermia was externally administered using the Thermotron RF-8 (Yamamoto Vinyter Co., Japan; Capacitive type heating machine) with parallel opposed electrodes. Thirteen dogs were used and allocated into one control group (N=3) and two treatment groups according to the treatment temperature. GroupI(N=5) was heated with 42.5+/-0.5degree C for 30 minutes, and GroupII(N=5) was heated with 45+/-0.5degree C for 15-30 minutes. Samples of liver tissue were obtained through a needle biopsy immediately afterhyperthermia and 7, 14 and 28 days after treatment and examined for SGOT, SGPT and alkaline phosphatase. Although SGOT and SGPT were elevated after hyperthermia in both groups (three of five in each group), there was no liver cell necrosis or hyperthermia related mortality in GroupI. A hydropic swelling of hepatocytes was prominent histologic finding. Hyperthermia with 45degree C for 30 minutes was fatal and showed extensive liver cell necrosis. In conclusion, liver damage day heat of 42.5+/-0.5degree C for 30 minutes is reversible, and liver damage by heat of 45+/-0.5degree C for 30 minutes can be fatal or irreversible. However, these results cannot be applied directly to human trial. Therefore, in order to apply hyperthermic treatment on human liver tumor safely, close observation of temperature with proper thermometry is mandatory. Hyperthermic treatment should be confined to the tumor area while sparing a normal liver as much as possible.

Hypematremia is a rare but important medical condition and is associated with mortality rate of 40 to 70%. However, little has been known about its prognostic factors or treatment guidlines. To evaluate the prognostic factors and the outcome following treatment, we reviewed 22 available medical records among twenty five hypernatremic patients (0.2%) in 12841 admissions at medical ward from January to December 1995. We defined hypernatremia as serum sodium concentration more than or equal to 150 mEq/L. Of these patients, two had hypematrernia at admission and the remaining patients became hypernatremic during admission. Mean peak serum sodium concentration was 158 (150-178) mEq/L and mean total body water deficit was 11.4 (6.7-21.3)%. Factors correlated with the development of hypernatremia were diverse and multiple, and the most frequent factor was diminished access to water. Mortality rate was 59%, but mortality was not correlated with age, correction rate of hyper-natremia, primary route of fluid loss, and the severity of hypernatremia or total body water deficit. Mortality rate was higher in patients whose serum sodium concentrations were below 130 mEq/L at admission (P<0.05). In our study, development of hypernatremia from initial hyponatremic state was significantly associated with poor outcome, and age, rapidity of correction, route of fluid loss, and the severity of hypernatremia or total body water deficit were not.

PURPOSE: Brain surface intensity model (BSIM)-based cortical thickness analysis does not require complicated 3D segmentation of brain gray/white matters. Instead, this technique uses the local intensity profile to compute cortical thickness. The aim of the present study was to evaluate intra-rater and inter-rater reliability of BSIM-based cortical thickness analysis using images from elderly participants. MATERIALS AND METHODS: Fifteen healthy elderly participants (ages, 55-84 years) were included in this study. High-resolution 3D T1-spoiled gradient recalled-echo (SPGR) images were obtained using 3T MRI. BSIM-based processing steps included an inhomogeneity correction, intensity normalization, skull stripping, atlas registration, extraction of intensity profiles, and calculation of cortical thickness. Processing steps were automatic, with the exception of semiautomatic skull stripping. Individual cortical thicknesses were compared to a database indicating mean cortical thickness of healthy adults, in order to produce Z-score thinning maps. Intra-class correlation coefficients (ICCs) were calculated in order to evaluate inter-rater and intra-rater reliabilities. RESULTS: ICCs for intra-rater reliability were excellent, ranging from 0.751-0.940 in brain regions except the right occipital, left anterior cingulate, and left and right cerebellum (ICCs = 0.65-0.741). Although ICCs for inter-rater reliability were fair to excellent in most regions, poor inter-rater correlations were observed for the cingulate and occipital regions. Processing time, including manual skull stripping, was 17.07 +/- 3.43 min. Z-score maps for all participants indicated that cortical thicknesses were not significantly different from those in the comparison databases of healthy adults. CONCLUSION: BSIM-based cortical thickness measurements provide acceptable intra-rater and inter-rater reliability. We therefore suggest BSIM-based cortical thickness analysis as an adjunct clinical tool to detect cortical atrophy.

Between January, 1990, and December, 1994, 105 elderly patients(over the age of sixty) were referred to the Division of Nephrology at the Seoul National University Hospital as acute renal failure(ARF) (serum creatinine >1.7mg/dL, patients who had been diagnosed to have acute on chronic renal failure were excluded). To find out the characteristics of ARF in the elderly, we made a retrospective study of our data. Sufficient data for analysis were available in 101 of these. Among these patients, prerenal failure occured in 5% of the cases, ischemic ATN 34%, toxic ATN 11%, renovascular obstruction 5%, glomerular disease 5%, postrenal failure 15%. Dialysis was required in 31 patients(31%). Twenty four patients were treated by hemodialysis, it was carried out in 1 patient by the peritoneal route, and the other 6 patients were treated by CAVH. The most common indication was hypervolemia(77%). Twenty seven patients died during the period of acute renal failure. The most common cause of death was infection(15 patients), and the others were underlying diseases, pulmonary complications and cardiovascular complications. Oliguria, and chronic underlying disease were poor prognostic factors. There were significant differences between living and died group in APACHE II score(P<0.05). We conclude that ischemic ATN is a more common cause of ARF in the elderly than in the younger, and presence of oliguria and chronic underlying disease are poor prognostic factors.
