PURPOSE: We evaluated if VEGF (Vascular Endothelial Growth Factor)-immunoreactivity is associated with tumor stage or grade in RCC (renal cell carcinoma), and specifically, if it could serve as a prognostic i ndicator in terms of survival. MATERIALS AND METHODS: Histologic samples of 54 patients in whom radical nephrectomy due to RCC (clear cell type exclusively) from January 1995 to July 1999 were included in this study. VEGF-immunoreactivity was classified as 0 to 3+ according to the ratio of VEGF-positive cells in randomly selected multiple tumor areas. Histologic differentiation was classified according to Fuhrmann's classification and staging was made with TNM classification. RESULTS: The correlation between grade and VEGF-positivity was statistically significant using chi-square analysis. Among the 3 patients with grade I, showed 2, 1, 0 for VEGF 1+, 2+, 3+ respectively. In grade II the cases were 11, 7, 3 respectively. In grade III the cases were 3, 10, 11, and in grade IV the cases were 1, 2, 3 respectively. The correlation between stage and VEGF-positivity didn't show statistical significance. The survival rate for VEGF during the period was 100%, 90%, 76.5% for VEGF 1+, 2+, 3+ respectively. The survival rate for grade was 100%, 100%, 83.3%, 66.7% for grade I, II, III, IV respectively. The survival rate for stage was 95.2%, 85.7%, 87.5%, 66.7% FOR STAGE I, II, III, IV respectively. In the same grade, survival rate decreased apparently according to the increase of VEGF-positivity. For example, in the same grade III, the survival rae was 100%, 90%, 72.7% for VEGF 1+, 2+, 3+ respectively. CONCLUSIONS: The results of this study is that VEGF is correlated with tumor grade and the higher VEGF expression, the lower the survival rate, so we can predict the prognosis by VEGF immunohistochemical staining for supplement of grading system. VEGF alone can be a good predictor for survival, and importantly in the same grade, we can differentiate patient's prognosis with VEGF.

Strongylodiasis is universal in distribution but is most abundant in countries with a tropical climate. Although infestation by Strongyloides stercoralis is usually limited to the intestines, dessemination of this helminth in debilitated host can be lead to death with various clinical disorders. characterized by profound malabsorption, diarrhea, electrolyte imbalance, gram negative or opportunistic fungal sepsis, coma and death. Cell-mediated immunity contributing significantly to the control of helminthic infections, may be suppressed by carcinoma, immunosuppressive chemotherapy and use of corticosteroids. Diagnosis of Strongyloidiasis is achieved by an examination of samples of feces, duodenal aspirates and sputum of patients for Strongyloides stercoralis. Treatment of strongyloidiasis is twofold : correction of the immunosuppressive state by withdrawal of immunosuppressive drug, if possible, and vigorous treatment with thiabendazole. Testing for strongyloidiasis is especially recommanded before treating a patients should be monitored for infection by Strongyloides stercoralis and other opportunistic infection. We are reporting a case patient with Strongyloides stercoralis hyperinfection and pulmonary tuberculosis who had been. used corticosteroid for persisting polyarthritis.

The various and serious types of disaster occur everyday and everywhere on the earth. There is no doubt that it is very timely to discuss about the effectiveness and preparedness of disaster. The purpose of this study is to develop a curriculum on the disaster management through reviewing disaster concepts and the disaster management system. For the empirical relevance of the study, researchers participated in a couple or more disaster training program, reviewed references, and consulted to the experts working on action parts in the area. As a result, the 'Integrated Disaster Management System Model(IDMSM)' was designed, in which four dimensions were explained. Then the 'Disaster Curriculum Model(DCM)' was explored with its theoretical framework based on the system model. The developed curriculum is composed of four levels ; the introductory course, the fundamental course, the advanced course, and the expert course. From this DCM, basically the course-outlines of two subjects in the introductory course, 18 subjects in the fundamental course(5 of direct services, 13 of indirect services) were developed. Also each course-outline was explored by its course objective, learning objectives, contents, and its length. Finally to make the most of the results, suggestions are proposed. The governmental considerations on the policy should support the systematic and integrated educational program to practice, appointing [Disaster School] or [Disaster Training Center] of relevance and accountabilities. The further study should explore the higher levels of the DCM through interdisciplinary efforts, and develop the text materials. The further study should explore the higher levels of the DCM through interdisciplinary efforts, and develop the text materials.

We applied arthroscopy in the diagnosis of thirty four patients with internal derangement of the knee from March to August, 1982. Its results were compared with clinical diagnosis and arthrographic findings. We also performed arthrofomy in twenty nine patients and the final diagnosis enabled us to evaluate the diagnostic accuracy of each method. The accuracy of clinical diagnosis was 63.4%. Arthrographic findings were correct in 77.8%. The diagnostic accuracy of arthroscopy was 92.3% with one false negative case. Unnecessary operations were avoided in five patients with the assistance of negative findings of arthroscopy. Arthrography and arthroscopy were complementary in the diagnosis of internal derangement of the knee.

Background: Hemophilia is life-threatening and hereditary bleeding disorder caused by deficiencies of pi coagulation VIII. IX, XI factor, and that is inherited by X-linkcd recessive. However, hemophilic treatment is getting increase in our country, but still insufficient or poor because of high cost, which is about 50000-70000$ per patient per year in other countries. Now, we need to detect hemophilia heterozygote (XAX*) or no symptomatic carrier among hemophiliac siblings (including mother, younger sister, sister) that is essential for prevention of hemophilia. We need to screen the mutation spectrum of FS and F9 gene among patients with hemophilia in order to detect hemophilia carriers. Objective: to detect a mutation 1'Ó ø! f9 gene among patients with hemophilia Methods: The blood samples were collected from paffeflf* who had been hospitalizing in department ot hematology of the First Clinical Hospital and the National Center for Maternal and Child Health from 2010 to 2011. We have carried out the screening of most common mutation named int- 22 inversion by Long-Range PC'R method is previously described by Lui Q et al.. 1998. Direct sequence method was used to detect the SNP and small deletion in patients who had no int-22 inv and large deletion. Results: In total, If pillitfhis with hemophilia (ÈË-14, IIB=1) participated in this study. The 9 patients positive for an int-22 inversion mutation, while the one patient had a multiple exon deletion (exon 1-13) which was demonstrated by repeated PC'R amplification failure. I wo missense mutation and 1 frame shift mutation were detected. The one patient had nonsense mutation but he was diagnosed as a severe hemophilia-A patient. Conclusion: We have to urgently adopt the molecular diagnosis and carrier detection ol hemophilia in our rnuntrv

Ventriculoperitoneal shunt (VP shunt) for hydrocephalus is thought to inhibit the closure of processus vaginalis by increasing intraabdominal pressure, thus it promotes the inguinal hernia. We reviewed the incidence and characteristics of the inguinal hernia in VP shunted patients, and tried to estimate the patency rate of processus vaginalis in early childhood. A reprospective review of patients undergone insertion of VP shunt between January 1980 and May 1998 at Seoul National University Children Hospital was done. 262 patients were included in this study. Among them, 28 patients developed inguinal hernia (10.7%). Six patients developed inguinal hernia before the insertion of VP shunt. According to the age of VP shunt, the inguinal hernia developed in 16.2% (12/74) of patients who had undergone VP shunt before 6 months old, 12.4% (11/89) between 6 months and 2 years old and 5.1% (5/99) after 2 years old. Among 22 patients excluding 6 patients who developed hernia before VP shunt, the incidence of inguinal hernia after VP shunt was 8.6% (22/256) with male predominance (M:F=18:4). 8 patients developed inguinal hernia bilaterally (36.4%). It is suggested that at least 14% of processus vaginalis is patent until 2 years old.

Authors analyzed the findings of findings of chest radiographs and high-resolution CT(HRCT) of chronic mercury vapor poisoning in 12 patients who were diagnosed by previous working history for mercury-thermometer and high level of mercury in blood and urine. The purpose of this paper is to introduce the HRCT findings of chronic mercury vapor poisoning. Duration of mercury exposure was ranged from 10 to 41 months(mean, 21.8 months). Estimated value of serum mercury was ranged from 3.6 to 8.7µg/dl(mean, 5.3 µg/dl: normal value is less than 0.5µg/dl). Estimated value of mercury in urine was ranged from 104 to 482µg/1(mean, 291.4µg/1: normal value is less than 20µg/1). Chest radiographs showed positive findings such as ground-glass opacities and peribronchial cuffings in only 2 out of 12 patients, but HRCT showed positive findings such as ground-glass opacities in 8 patients, peribronchial cuffings in 7 patients, centrilobular abnormalities in 5 patients, interface sign in 4 patients, interlobular septal thickening with intralobular lines in 2 patients and lobular consolidation in one patient. In conclusion, chest HRCT is superior to chest radiograph to show the pulmonary manifestation of chronic mercury vapor poisoning. In patients with chronic mercury vapor poisoning, HRCT findings of centrilobular distributed ground-glass opacities and peribronchial cuffinges are characteristic.
