Giant condyloma and carcinoma-like condyloma is relatively rare. Although it has histological similarities to condyloma acuminata, it is believed by most authorities to be a clearly defined variant of epidermoid carcinoma. Clinically it is easily mistaken for the more aggressive metastasing epidermoid carcinoma. The legion was first described by Buschke in the German literature in 1896. as a varient of condyloma acuminata. A case of malignancy of the penis which have apparently been transformed from giant condyloma acuminata of the penis are herein presented with review of literature.

Fractures of the acetabulum are relatively uncommon. But if fractures of the acetubulum are not accurately evaluated, classified, and reduced anatomically, major sequalae and complications are frequently developed. Because of complicated anatomy, difficulty with surgical exposure, severe comminution, and major associated injuries, the treatment of displaced acetabular fractures between conservative and operative methods is still controversial. We reviewed thirty five cases of displaced acetabular fracture treated operaively from January 1984 to December 1991. The prevalent age was the fourth decade. There was twenty seven cases of associated injuries, twenty two dislocations of the hip. According to the Letournel's classification, the most common fracture type was posterior wall and both column type. The fracture was fixed internally with only screws in thirteen cases and with plate and screws in twenty two cases. Among thirty five patients, five patients were lost in the follow up and another five patients had followed up lesser than one year. The mean duration of follow-up afrer the operation was three years (range, one to eight years). Among twenty five patients who had followed up more than one year, the satisfactory results were achieved in nineteen patients (76%) and the poor results were achieved in three patients (8%). The complications were post-traumatic arthritis, avascular necrosis of femoral head, osteomyelitis in iliac bone, skin necrosis, and heterotopic ossification.

PURPOSE: recent studies have reported that the expression of Drg-1 is up-regulated by androgen. It has been suggested that Drg-1 gene be used as a molecular marker for prostate cancer therapies like PSA. To de termine the role of Drg-1 gene as a molecular marker during intermittent androgen deprivation(IAD) therapy, we investigated the expression of Drg-1 and compared it with PSA expression in human prostate cancer cell lines treated with dihydrotestosterone (DHT) continuously or intermittently. MATERIALS AND METHODS: Two prostate cancer cells having different status of androgen receptor [LNCaP (androgen dependent) and PC-3 (androgen independent)] were used in this study. To know the change in PSA and Drg-1 expression after DHT treatment the cells were cultured in steroid-free RPMI media for 24 hours. 10(-7) and 10(-8)M of DHT and 10(-7)M bicalutimide was added into the cells and then cultured for 72 hours. And we established in vitro IAD model using LNCaP cells. Northern analyses were performed to determine the expression level of both PSA and Drg-1genes. Also, western analyses were performed to determine the protein level of proliferating cellular nuclear antigen and androgen receptor. RESULTS: Transcripts of Drg-1 were detected in both LNCaP and PC-3 cells but PSA was not expressed in PC-3 cells. The expression of Drg-1gene in LNCaP cells was up-regulated by 10(-8)M of DHT like PSA gene and down-regulated by 10(-7)M bicalutamide. In the treatment of intermittent androgen deprivation, the expression pattern of Drg-1was similar to that of PSA. However, up-regulation of PSA was detected earlier than of Drg-1. CONCLUSIONS: Based on observation, Drg-1 was up-regulated by androgen and down-regulated by anti-androgen. This suggests that Drg-1gene is useful for determining the androgen independency of prostate cancer during IAD.

6.In Vitro Potentiation of 5-Fluorouracii-lnduced Cytotoxicity by Leucovorin in Human Bladder Cancer Cell Lines.
Korean Journal of Urology 1997;38(1):7-12
Several experimental and clinical studies have shown that leucovorin(LV) potentiate the antitumor effect of 5-fluorouracil(SFU) by biochemical modulation. LV increases the intracellular reduced folate, which stabilizes the 5FU metabolite 5-fluorodeoxyuridine monophosphate (FdUMP):thymidylate synthase(TS) complex, thus increasing the block in the DNA synthesis pathway. This present study was designed to analyze the cytotoxic effects of the combination of 5FU and LV in bladder cancer cell lines. We used two human bladder transitional cell cancer cell lines (DU4184 and DU4284): In vitro cytotoxicity was assessed by the colorimetric assay. Them was a substantial difference of 5FU cytotoxicity between two cell lines. DU4284 cells were 2-fold less sensitive to 5FU than DU4184 cells (mean IC50 : 0.43M+0.02 vs. 0.21+0.0l.uM). Enhanced cytotoxic effect of 5FU by coadministration of LV was seen in both cell lines with the greater degree of potentiation being observed in DU4284 cells (enhancement factor: 7.2 vs. 2.7 fold, respectively). It is concluded that, in this study, 1) bladder cancer cells reveal various patterns of cytotoxic responses to 5FU only, 2) LV significantly enhances the cytotoxicity of 5FU in bladder cancer cells including the 5FU- less sensitive cells. These data support the use of LV in combination with 5FU as adjuvant treatment of patients with advanced metastatic bladder cancer.

This series represents 128 cases of acute gonococcal urethritis treated with doxycycline at the Seoul Red Cross Hospital from the 1st. May to.5th, Oct., 1969. Results of this treatment were divided in three groups: Group I ; Single dose of doxycycline, 300 mg. was administered for this group. 36 cases fall into this category. Cure rate for this group was 36%. Group II; Doxycycline, 200mg. was given on the 1st treatment day and daily dose of 100 mg. for 4 ensuing days. 42 cases were included to this group. Cure rate was 72%. Group III Daily dose of 200 mg. was administered for the remainders, 50 cases for 5 consecutive days. Cure rate was 91%. It was concluded that 200 mg. of doxycycline daily for 5 days dose regime can be recommended for the treatment of acute gonococcal urethritis, especially in cases allergic to penicillin or in which penicillin treatment fails. No anaphylactic shock or some other undesirable side reaction in administering this drug was experienced.

Partial trisomy 10q syndrome is a rare chromosome anomaly characterized by severe mental and growth retardation, craniofacial dysmorphia with prominent forehead, fine arched eyebrows, deep set small eyes and micrognathia, In addition, other physical manifestations have been reported as skeletal anomaly, congenital heart disease, inguinal hernia, and so on. We report a case of partial trisomy 10q syndrorne with certain stigmata which confirmed by chromosome analysis.
