Based on our experience with 23 frontotemporal reconstructions performed, this paper attempts to provide guidelines for appropriate selection among the four most commonly employed materials (e.g., autogenous parietal bone, silicone rubber, methylmethacrylate, and porous polyethylene) so that optimal results can be achieved. Clinical follow-up ranged from 6 to 91 months (mean 32 months). Every patient was analyzed clinically by ordinary scale method. The mean defect size was 134.8 cm2 in the silicone rubber, 36.5 cm2 in the methylmethacrylate, 17.4 cm2 in the autogenous bone graft and 7.3 cm2 in the porous polyethylene. The clinical assessment was excellent (mean, 29.3 points) in silicone rubber, excellent (mean, 28.6 points) in autogenous bone, excellent (mean, 26.8 points) in methylmethacrylate, and good (mean, 24.8 points) in polyethylene. To sum up, a large bony defect of congenital calvarial anomaly produced an excellent result using custom-made silicone implant. A relatively small bony defect with a scarred bed produced an excellent result using autogenous parietal bone grafting. Unexpected and medium-sized defect was reconstructed successfully through a simple procedure using methylmethacrylate. Porous Polyethylene was used at an incidental small defect because of its expensiveness.

PURPOSE: To report the results of acetabular revisions performed with the cementless, hemi-spherical porous coated component supported by viable host bone and minimal allobone graft for acetabular deficiencies. MATERIALS AND METHODS: A retrospective study was completed for 22-revision acetabular components, using the cementless hemispherical porous coated prosthesis and minimal femoral head allograft. There was an average follow up of 48 months, with a range of 24 to 84 months. Radiographic measurements were performed in several aspects; cup-allograft contact, inclination, vertical and horizontal migration of acetabular cup, and acetabular zone by modified zone of DeLee and Charnley, in which location, size and progression or non-progression of radiolucent zone were recorded. The acetabular deficiencies were classified by the American Academy of Orthopaedic Surgeons Committee and were type I in 2 hips (9%), type II in 12 hips (55%), and type III in 8 hips (36%). Twenty acetabular cup cases of Harris-Galante II were used in this study, 1 case of Harris- Galante I, and 1 case of Duraloc. The average size of the cup was 57(44-66) mm. RESULTS: The average cup-allograft contact was 72.5% in 19 cases and we could not differentiate the margin between the host bone and the allograft in 3 cases. There was no significant vertical or horizontal migration of acetabular cup. Radiolucent zones in follow-up radiographs were 8 cases in zone IA, 4 cases in zone IB, 4 cases in zone IIB, 9 cases in zone IIC, 8 cases in zone IIIA, and 7 cases in zone IIIB. One case showed 2 mm radiolucent area in zone IIC and another case showed 3 mm radiolucent area in zone IIB, but the radiolucencies were not progressive. The remaining cases showed less than 0.5 mm radiolucent area or no radiolucent zone. The average period of bony incorporation was 13.1 months. CONCLUSIONS: We suppose that acetabular revision with the cementless hemispherical porous coated cup supported by viable host bone and minimal bone graft produces good results.

7.Diagnostic Efficacy of the Combination of Urine Cytology, Urinalysis and History in the Follow-up of Bladder Tumor.
Korean Journal of Urology 1991;32(6):894-901
We studied a retrospective analysis of the diagnostic value of the non-invasive modalities in 6O patients with primary superficial bladder tumors (pTa, pT1) who underwent treated at the Han. yang University Hospital From March 1980 to February 1990. In this study, using empirical cystoscopy follow-up scheme. 17 cystoscopies had to be done to detect each new recurrence. Because of this excessive number of cystosoopies. the diagnostic value of the combination of the following tests were calculated and the sensitivity of the following tests (singly and combined) has been assessed ; (l) urine cytology, (2) red blood cell count in urine sediment and (3) history of symptoms or irritative bladder and hematuria. This study indicated that a combination of non-invasive tests may produce a more rational approach to the follow-up of patients with low stage. low grade transitional cell carcinoma by minimizing the number of cystoscopies. The result indicated that over all recurrence rate was 36.7% (22,60) and 19 cases (86%) were recurred within 2 years and these patients had poor prognosis than patients after 2 years. There were significant increase of recurrence in initial high stage, high grade. high class tumors and the recurrence rate was decreased in patient with instilled adriamycin more than 10 times. The combination of these non-invasive diagnostic tests may constitute a sensitive procedure for the follow-up of bladder tumors. In the case of grade III and muscle-invasive recurrences (>T1), the sensitivity rate was 100%.

OBJECTIVE: It is known that normal follicular growth and pregnancy are possible using Follicular stimulating hormon(FSH) alone during controlled ovarian hyperstimulation(COH) for IVF-ET. The purpose of this study was to compare and analize the results of COH for IVF-ET between a group using only FSH-HP and a group using FSH/hMG METHOD: 111 cycle of the total 280 COH for IVF-ET cycles belonged to the FSH-HP group, and the FSH/hMG group accounted for remaining 169 cycles. The amount of gonadotropin administered, the duration of hormonal therapy, the number of embryos transfered, the endometrial thickness, and the pregnancy rate were compared between the two groups and statistically analized using the t-test. p values less than 0.05 deemed statistically significant. RESULT: There were no statistical differences on the amount of gonadotropin administered, the duration of hormone therapy, number of oocytes retrieved, nor the endometrial thickness between the two groups. However,the serum E2 level was significantly lower, and the number of embryos of high quality(GradeIandII) significantly higher in the FSH-HP group. In pregnancy rate, FSH-HP group shows higher than FSH/hMG group(38.8% VS 34.2%). but the difference was not large enough to be considered statistically significant. CONCLUSION: The results of this study show that compared to using FSH/hMG, treatment with FSH-HP alone allowed the retrieval of more embryos of high quality, and although not statistically significant, achieved a higher pregnancy rate, thus indicating that it can be used as an effective method for COH.
