To know the correlation between glomerular and tubulointerstitial lesion and to define the characteristics of interstitial inflammatory cell in IgA nephropathy and classified according to WHO classification and graded tubulointerstitial lesion as mild, moderate and severe. Paraffin-embedded 5u sections were stained with UCHL-l, L26 and CD68 antibodies. More than 20 fields were examined in each case under the high power microscopy and the number of positive cells were counted. There was positive correlation between the severity of glomerular and that of tubulointerstitial lesion. The mostcommoninflammatory cells in the interstitiuin were UCHL-l positive cells followed by CD68 and L26 positive cells. As the WHO grade or tubulointerstitial lesion increased, the numbers of positive cells were increased in all three groups. The proportion of UCHL-1 Positive cells were increased in cases with high WHO grade whereas that of L26 positive cells incases with severe tubulointerstitial lesion Proteinuria was correlated with the degree of inflammatory cell infiltration, especially with that of L26 positive cells.

We report a case of an erythrodermic form of mycosis fungoides in a 68-year-old male, who showed generalized erythroderma with scales for 3 months. Lymphadenopathies in the inguinal and neck areas were present. Histopathological findings showed epidermotropism, perivascular atypical lymphocyte infilteration in the upper dermis, and dermatopathic lymphadenopathy in the inguinal lymph node. T cell markers were positively stained in the immunohistochemical study. These clinicopathological features were consistent with an erythrodermic form of mycosis fungoides(TNM IIl). The patient was treated with PUVA therapy and low dose chemotherapy.

Patient survival is one of the most important measures for the evaluation of progress in cancer patient care across the wide spectrum from diagnosis to treatment. The optimal monitoring method for cancer patient survival is to estimate survival based on representative data from cancer patients in the population, which is only achievable through using population-based cancer registration data. Relative survival is used to compare the survival experience in a study cohort that expected to result from background population mortality rates. This technique is useful when the cause of death is not accurate or not available, since it provides a measure of excess mortality in a group of patients with a certain disease. The purpose of this article is to demonstrate the procedures for estimating relative survival using the statistical software Stata. For this survival analysis to show the procedure, the example data set was randomly selected from the National Cancer Incidence Database, which was used in a recent article reporting the overall relative survival of cancer patients diagnosed during 1993-2002 in Korea.

Patients with breast lesion suggestive of malignancy underwent Tc-99m MIBI scan in order to assess the value of this technique in the detection of breast carcinoma and axillary lymph node metastasis. One hundred five patients with breast lesion underwent 99m-MIBI scan before biopsy. 20mCi of Tc-99m MIBI was given intravenously in contralateral arm of the breast lesion and planar prone lateral and supine anterior views for 10 minutes each were taken. Pathological diagnoses were carcinoma in 77 breasts of 76 patients and benign in 29 patients. Pathologic types were DCIS in 4, IDC in 62, mucinous carcinoma in 3, medullary carcinoma in 2 and others in 6. The pathologic tumor status was DCIS in 4, T1 in 27 ,T2 in 30, T3 in 6, T4 in 4 and Tx is 6 cases. All patients with multiple lesions were positive. The sensitivity of Tc-99m-MIBI scan was 95%(73/77) and specificity was 69%(20/29). Sensitivity of mammography and ultrasonography were 85% and 82%. Axillary metastasis study showed 68% sensitivity and 92% specificity. The Tc-99m MIBI scan is a highly effective method in the diagnosis of breast cancer.

PURPOSE: Sentinel lymph node (SLN) biopsy is a useful method for assessing axillary nodal status and selecting axillary dissection in breast cancer patients. The goals of our study were to evaluate the detection rate of SLN and determine the accuracy of SLN biopsy in predicting axillary nodal status using technetium radiolabeled sulfur colloid and isosulfan blue dye. METHODS: Between January and August 2001, 55 breast cancer patients with clinically node negative results underwent SLN biopsy from the Department of Surgery at Ajou University Hospital. Both technetium radiolabeled sulfur colloid and isosulfan blue dye were used to guide SLN biopsy. SLN biopsy was always followed by a complete axillary dissection. The histopathology of SLNs determined from frozen sectioning and serial sectioning was compared with that of the nonsentinel nodes evaluated with routine Hematoxylin and Eosin stain. RESULTS: The overall SLN detection rate was 85.4% (47 of 55 patients). The staging accuracy of SLN biopsy was 97.9% (46 of 47 patients), the sensitivity 92.3% (12/13), the false negative rate 7.7% (1/13), and the negative predictive value 97.1% (34 of 35). CONCLUSION: Our study was a pilot study for SLN biopsy. SLN biopsy was more effective when a combination of technetium radiolabeled sulfur colloid and isosulfan blue dye were used. The results of our study support the hypothesis that SLN biopsy is an accurate predictor of axillary nodal status. SLN biopsy may be applicable to early breast cancer patients and thereby allow the omission of routine axillary dissection in selected cases.

Caveolin-1 (CAV1) is an integral membrane protein that may function as a scaffold for plasma membrane proteins and acts as a tumor suppressor protein. One causative factor of chemotherapy- resistant cancers is P-plycoprotein (P-gp), the product of the multidrug resistance-1 gene (MDR1), which is localized in the caveolar structure. Currently, the interactive roles of CAV1 and MDR1 expression in the death of cancer cells remain controversial. In this study, we investigated the effects of indomethacin on the cell viability and the expression levels of MDR1 mRNA and protein in a CAV1- siRNA-mediated gene knockdown hepatoma cell line (SK-Hep1). Cell viability was significantly decreased in CAV1-siRNA-transfected cells compared with that of control-siRNA-transfected cells. Furthermore, the viability of cells pretreated with CAV1 siRNA was markedly decreased by treatment with indomethacin (400micrometer for 24 h). However, the protein and mRNA levels of MDR1 were unchanged in CAV1-siRNA-transfected cells. These results suggest that CAV1 plays an important role as a major survival enzyme in cancer cells, and indomethacin can sensitively induce cell death under conditions of reduced CAV1 expression, independent of MDR1 expression.

PURPOSE: The aim of this study was to assess the clinical utility of the known CT signs of the traumatic rupture of the diaphragm. MATERIALS AND METHODS: CT scans and chest radiographs were retrospectively reviewed in 13 patients who had diaphragmatic rupture confirmed by surgery. On chest radiographs, the elevation of the diaphragm was evaluated. On CT, 1) discontinuity of the diaphragm, 2) lack of depiction of the diaphragm surrounding the herniated intraabdominal organs (absent diaphragm sign), and 3) fat seen lateral to the diaphragm (fat sign) were evaluated. RESULTS: Chest radiographs showed the elevation of the diaphragm in 11 patients (85%). CT scan showed absent diaphragm sign in 11 patients (85%), discontinuity of the diaphragm in 8 (62%), and fat sign in 7 (54%). All of 12 patients who had the left diaphragmatic rupture had one or more of the above findings. CONCLUSION: Discontinuity of the diaphragm, absent diaphragm sign, and fat sign may be helpful CT findings in the diagnosis of the traumatic rupture of the left diaphragm.

Cushings syndrome in pregnancy is rare. This is explained by the syndromes association with amencerhea, infertility and abortions. Matemal and fetal risks increase markedly when pregnancy does occur in woman with hypercortisolism. Since pregnant women without Cushings syndrome develop some features of Cushings syndrome, such as hypertension, hyperglycemia and striae, a high index of clinical suspician must be maintained to prevent delay in diagnosis. The physiologic changes in adrenocorticostemid metabolism during pregnancy further complieate the diagnosis. We describe a case of Cushings syndmme in pregnancy secondary to an adrenal cortical adenoma which was diagnosed immediately after a preterm delivery in 24-year-old woman with preeclampsia.
