Meningioma is the most common neoplasm of central nervous system which is hardly diagnosed by cytologic examination. However, preoperative cytologic diagnosis can be easily made in the case of extracranial meningioma, especially in head and neck lesion. We recently experienced a case of fine needle aspiration cytology of meningioma in submandibular area of a 24 year-old male patient. The smear revealed high cellularity in the clean background. Individual tumor cell of nests or syncytium had round or oval nuclei with fine chromatin and moderate amount of lightly stained cytoplasm with indistinct mar- gin. Characteristic cellular whorls, intranuclear inclusions and scattered psammoma bodies made it easy to diagnose a meningioma.

Henoch-Schonlein purpura is a common pediatric disease presenting most frequently with skin, gastrointestinal, joint and renal manifestations. But in cases are infrequently only severe gastrointestinal manifestations. It is hard to diagnose promptly and exactly. Clinical manifestations and laboratory findings were observed and analyzed in 20 cases with Henoch-Schonlein purpura which were considered as acute abdomen, hospitalized at Kyung Hee university Hospital during the period from December, 1982 to September, 1992. The following results were obtained; 1) The age distribution of Henoch-Schonlein purpura had a peak incidence between 7 to 9 year old. And male preponderance was observed with male to female ratio of 2.33 to 1. 2) The most prevalent season for the initial presentation of Henoch-Schonlein purpura was in fall: in 10 cases (50%). 3) The frequency of each type of clinical manifestations showed 20 (100%), 20 (100%), 18 (90%), 8(40%) cases for skin, gastrointestinal, joint and renal manifestation respectively in order of frequency. 4) The common previous illness were URI, 40 cases (50%) and allergy, 2 cases (10%). 5) The onset time of skin manifestation from admission were 1 to 4 days (75%0, 5 to 8 days (15%), 9 to 12 days (10%) explolaparotomies were done the last 2 cases. 6) In all cases, X-ray study (100%), abdominal sono (50%), Meckels scan and colon study (5%) respectively were done. 7) Hematologically leukocytosis over 10,000/mm3 was observed in 80% of cases and increase in ESR over 20 mm/hr in 65% of cases. Coagulation studies, immunologic and complement level revealed the result within normal range in most of the cases. 8) Among 8 cases with renal involvement, all cases had both hematuria and proteinuria. 9) Most cases were recovered within 4 weeks but in 4 cases, renal biopsies were done because of relapse. The results were Meadow classification grade I (1 case), II (1 case), IVa (2 cases). After renal biopsy, steroid pulse therapy was started.

PURPOSE: The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyme and renal collecting systems are invaded simultaneously. MATERIAL AND METHOD: We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renalcontour bulging or reniform shape, location of mass center, intact parenchyme overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. RESULT:There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cellcarcinima, wherea and nine of 12 cases of transitional cell carcinoma maintained the reniform appearance. This is significant statiscal difference between the two(p<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(p<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, whereas 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(p<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(p<0.05). CONCLUSION: CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reniform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change.

Transcatheter arterial chemoembolization(TACE) is an imperative method for the managment of inoperable hepatocellular carcinoma(HCC). It is well known that primary HCC frequently invades the portal venous system and forms a tumor thrombus obstructing the portal blood flow which makes unfavorable prognosis of patiebt. We retrospetively reviewed 58 patients who reveived TACE(minimum 3 times) of HCC invading into portal venous system. Group 1(n=29) which showed peripheral portal vein invasion had better clinical and laboratory response. Group 2(n=17) which showed first order portal branch invasion had similar response to Group 3(n=12), which had main portal invasion. Group 1 showed no difference in survival time between TAC and TACE, but, in Group 2 and 3, emboliation with chemotherapy made longer survival than chemotherapy only. Clinical level of AFP was meaningful in Group 1 and 2 as decreasing value. Our results provides that careful selection of TACE and case by case Coil/Gelfoam embolization can improve the mean survival and clinical response when HCC evidently invades portal venous system.

This study was to find out whether the rendering screen difference affect to measuring distance in a CAD program according to three types of CAD programs. Materials and methods: The model presented in ISO 12836 for dental scanner evaluation was reduced by 70%. This model was repeatedly scanned 15times using Trios II (3Shape, Denmark). Using the output STL file, 3Shape CAD, inLab 15, and ExoCAD programs were used to measure the horizontal distance (H) and vertical distance (V) between adjacent point angle, and for each experiment, three groups were set according to the CAD program type. Statistical analysis was performed using One-way ANOVA test and post hoc was performed using Dunnett T3 test. Results: In the horizontal and vertical distance measurement, there was no difference in the average of the measured values between the three groups according to the CAD program (P>.05). Conclusion: There were no effect of the difference in the rendering screen in the horizontal and vertical linear distance measurements of the inlay model on the dental CAD program.

PURPOSE: Laparoscopic instruments have been remarkably developed through many trials. Various studies and experiments on laparoscopic instruments are underway in other countries. Laparoscopic surgery is also very actively applied in Korea. However, research on the use and safety of the instruments is stagnant. Furthermore, reuse of some disposable laparoscopic instruments is frequently observed, but there are only rare studies on the safety of this. Thus, we tried to provide study cases on the safety of repeated use of disposable laparoscopic instruments. METHODS: To investigate the effectiveness of sterilization and a re-package procedure, we divided the laparoscopic instruments that are commonly used in our institution into 10 types. Among all the available instruments, 32 instruments were selected for the simulation experiment. Each instrument was sterilized using ethylene oxide gas or glutaraldehyde 2%, and then packaged. Then, each was observed grossly and microscopically under aseptic conditions and we looked for any remnant foreign body or contaminant. When remnant foreign body or contaminant was found, they were collected and separately cultured. RESULTS: Residual contaminants were found in 15 instruments (46.9%) out of a total of 32 and microorganisms, including coagulase-negative staphylococcus and gamma-hemolytic streptococcus, were cultured from (9.38%), and each had different types of microorganisms. CONCLUSION: It is remarkable that the bacteria were cultured from recycled laparoscopic instruments after sterilization. The reuse of laparoscopic instruments might be cost-effective, but further studies on its safety are required. Moreover, careful inspection on the method of surgical instrument sterilization in each institution will be necessary.

Aneurysmal fibrous histiocytoma(AFH) is a histologic variant of dermatofibroma. The importance of the recognition of AFH as a variant of dermatofibroma lies in the differential diagnosis because the histologic appearance of AFH is very similar to dermatofibrosarcoma protuberans and other vascular malignancies, such as Kaposi's sarcoma and angiosarcoma. A 32-year-old man was seen for a nodular mass on the right popliteal fossa of 4 years' duration. The excisional biopsy specimen showed a relatively well circumscribed tumor mass in the dermis. In addition to compact storiform proliferation of spindle cells, there were multiple, irregular, blood-filled, aneurysmal tissue spaces that were devoid of lining of endothelial cells. Also, deposition of hemosiderin was prominent, particularly in the periphery of the aneurysmal spaces. Immunohistochemical stain for CD34 were negative to most tumor cells. After excisional therapy, there was no evidence of recurrence during the period of ten months' follow-up.

OBJECTIVE: The purpose of this study was to compare the effectiveness, easiness, postoperative complications between tension-free vaginal tape (TVT) and Burch colposuspension (BC) in the surgical management of female genuine stress urinary incontinence. METHODS: A retrospective study of 77 cases with stress urinary incontinence at Department of Obstetrics and Gynecology and Urology, Pochon CHA University Medical College from January 2000 to December 2002, followed up more than 6 months. All of 77 cases were above grade 2 genuine stress urinary incontinence, 37 cases were performed tension-free vaginal tape, 40 cases were performed Burch colposuspension. RESULTS: Cure rate was 91.4% in the tension-free vaginal tape (TVT) group, 90% in the Burch colposuspension group. The mean operative time for TVT was 23.4 minutes and for Burch colposuspension was 47.2 minutes. The mean hospital stay in TVT was 1.8 days and in Burch colposuspension was 5.2 days. The incidence and severity of postoperative complication is similar in both groups. CONCLUSION: The cure rates of TVT were comparable with Burch colposuspension in the surgical management of female genuine stress urinary incontinence. And the incidence and severity of postoperative complication is similar in both groups. Moreover TVT is simple procedure more than Burch colposuspension.
