Mandibular condylar fracture is common in mandibular fractures. Unlike other facial, skeletal fractures, most of mandibular condylar neck or head fractures are treated with closed reduction and subsequent functional therapy is essential for preventing complications including ankylosis, arthrosis and growth disturbance. From January, 2000 to September, 2002, we have treated 15 cases of mandibular condylar fractures with closed reduction by using functional appliance with bite block. Among these cases, we report a case of 14-year-old female with mandibular condylar neck fracture, resulted in good clinical and radiographic progress.

BACKGROUND: Immediate implant placement has become an acceptable treatment for the edentulous area. The advantages of the immediate implant placement include considerable decrease in time from tooth extraction to placement of the finial prosthesis, fewer surgical procedures, and better acceptance of the overall treatment plans. But the success is dependent on the quantity and quality of the extraction socket. The purpose of this study is to evaluate the success of the immediate implant placement. MATERIALS AND METHODS: Twenty-one sites in 16 patients were selected for the evaluation of the immediate implant placement. All of the cases were followed using clinical and radiographic examinations. Criteria of success were the absence of peri-implant radiolucency, mobility, and persistent pain or sign of infection. RESULTS: Of the 21 implants, 13 implants have been succeeded. Of the 13 implants, 10 implants were replaced for the periodontal disease and 3 implants were replaced for the trauma. CONCLUSION: The criteria of the success in immediate implant placement are as follows. 1) Implants placed into fresh extraction sockets have a high rate of survival. 2) Implant should be placed as close as possible to the alveolar crest. 3) Implant placed into available bone beyond the apex have a high success rate.

Intracranial lipoma usually occurs at or near the midline, predominantly in the callosal cistern and very rarely in the sylvian fissure. We report a case of lipoma of the sylvian fissure without association with other congenital anomaly or vascular abnormality.

We present two cases of compression of the common hepatic duct by overriding of the right hepatic artery. One case is gall bladder, common hepatic duct stone and one case is right intrahepatic duct stone. We observed the compression of the common hepatic duct caused by overriding of the right hepatic artery in the both cases. The final diagnosis was made at operative fields. These patient were successfully treated by dissection of adhesion, suture, fixation between gall bladder bed and right hepatic artery.

PURPOSE: The aim of this study is to correlate the non-characteristic dual-phase CT imaging findings of hepato-cellular carcinoma with the observed characteristics of surgical specimens. MATERIALS AND METHODS: We studied four cases in which homogeneous low attenuation was observed during the arterial and delayed phases of dynamic CT scanning and in which hepatocellular carcinoma with coagulation necrosis above 95% was pathologically confirmed. We compared the findings of dual phase CT scanning, ultrasonography, angiography and Lipiodol CT scanning with the observed features of surgical specimens. RESULTS: Nodules were 30-50 (mean, 41) mm in size, and were round in three cases and oval in one. In all four cases, a low density lesion was observed during the arterial and delayed phases of dual-phase CT scanning. Ultrasonography demonstrated internal echo and the presence of a hypoechoic halo, implying that in all cases a capsule was present. At angiography and LiCT, minimal peripheral and central tumor staining or lipiodol up-take was observed. In all surgical specimens a complete capsule was visible, and histologic structures were mainly of the trabecular type, Edmondson grade II or III was recorded, and the mass had undergone extensive coagulation necrosis (above 95%). CONCLUSION: In cirrhotic liver which is hepatitis B-antigen positive, clear sonographic findings of internal echo and a capsule, rather than a simple cyst, indicate the possibility of hepatocellular carcinoma with extensive coagulation necrosis. This is so even if the arterial and delayed phases of dual-phase CT scanning indicate the presence of a low-density lesion, and in such cases additional work-up is therefore required.

PURPOSE: Taxol (Paclitaxel) is a new generation of chemotherapeutic drug proven to be effective in the treatment of many cancers. In this study, to further demonstrate the differential effect of the tumor suppressor gene, p53, on the Taxol-induced apoptosis in osteogenic sarcoma cell lines, we used p53-defected SaOS2 cells and wild type p53-expressed U2OS cells. MATERIALS AND METHODS: The cell viability was measured by the XTT assay. To examine whether the differential expressions of p53, in U2OS and SaOS2 cells, were associated with Taxol-induced apoptosis, DNA fragmentation assays were performed on both cytosolic and genomic DNA. Since the cleavage of poly (ADP-ribose) polymerase (PARP) is primarily responsible for apoptosis, the cleavage of PARP, and the expression of cyclin B1, polo-like kinase, Bax, Bcl-xL, Bcl-2 in U2OS and SaOS2 cells were compared by Western blot analyses. RESULTS: The cell viability of the p53-defected SaOS2 cells was markedly decreased with Taxol treatment. Whereas, the cell viabilities due to 6-mercaptopurine and adriamycin were no different between the U2OS and SaOS2 cells. Treatment with Taxol induced a ladder- like pattern of DNA fragments, which is a biochemical hallmark of apoptosis, consisting of multiples of approximately 180-200 base pairs, in a dose-dependent manner in the SaOS2 cells, but insignificantly with the U2OS cells. When the cells were treated with Taxol, the 89 kDa cleavage product of PARP clearly appeared as a function of time in the SaOS2 cells, but not in the U2OS cells. The Taxol-induced apoptosis in p53 defected-osteogenic sarcoma cells was associated with the PARP cleavage as a result of the increased activity of caspase 3, and the high expressions of cyclin B1 and PLK. Bax, as a proapoptotic factor, was increased in the SaOS2cells, but the Bcl-xL and Bcl-2 were decreased when the cells were exposed to 10miceoM Taxol. CONCLUSION: From these results, it was concluded that p53-defected SaOS2 cells are much more sensitive to Taxol-induced apoptosis than p53-expressed U2OS cells.

Candida albicans cystitis is an uncommon but well described complication of modern therapeutics. The significance of systemic factors in the defense of the urinary tract against candidal infection is unknown. However, secretions from the prostate grand in men and from periurethral glands in women have been reported to be fungistatic. Conditions that predispose to candiduria include diabetes mellitus, antibiotic and corticosteroid therapy and disturbance of urine flow. Cystoscopy with bladder biopsy are necessary to rule out bladder tumor. We report a case of BPH with candidal cystitis and review the relevant literatures.
