1.Intraosseous Ganglion of the Scapular Glenoid: A Case Report.
The Journal of the Korean Bone and Joint Tumor Society 2012;18(1):37-40
Intraosseous ganglion is a benign cystic lesion. It is composed of fibrous tissue with mucoid changes located in the subchondral bone adjacent to a joint. Intraosseous ganglion has been reported in various skeletal sites and most commonly in the lower end of the tibia and femur. However reports of intraosseous ganglion of the glenoid are rare, with only 14 cases in the literature. We repot 2 cases of intraosseous ganglion of the glenoid with literature reviews.

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.

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.

The purpose of present study is to compare the effect of treatment using Guidor(R) as a barrier membrane in conjunction with platelet-derived growth factor and insulin like growth factors on experimental dehiscence defects. Following the resection of premolar crowns, roots were submerged. After 12 weeks of healing period, experimental dehiscence defects of 4mm in height and 4mm in width were surgically created on the mid-facial aspect of the lower premolar roots in each of 4 adult dogs. After root planning and demineralization of the root surface with citric acid, the control groups received 4% methylcellulose gel only, the test group I received 4% methylcellulose gel and were covered by Guidor(R) and the test group II were treated with PDGF and IGF and 4% methylcellulose gel with Guidor(R) coverage. Histological and histomorphometric analysis following 8 weeks of healing revealed the following results. 1. The new bone formation showed no statistically significant difference in all groups with 0.59+/-0.82mm(14.03+/-19.60%) for control, 0.70+/-0.39mm(16.30+/-9.01%) for group I, 0.87+/-0.76mm(18.74+/-16.03%) for group II. 2. The new cementum formation showed no statistically significant difference in all groups with 0.54+/-0.48mm(16.38+/-14.57%) for control, 0.95+/-0.38mm(23.43+/-9.30%) for group I, 1.01+/-0.75mm(22.10+/-16.11%) for gorup II. 3. The root resorption showed statistically significant differences betweenthe control group and all test groups(p<0.05) with 2.11+/-0.53mm(52.93+/-12.32%) for control, 0.63+/-0.27mm(15.32+/-7.05%) for group I, 0.89+/-0.33mm (19.26+/-7.11%) for group II. On the bases of these results, there were no statistically difference between treatment using resorbable membrane and resorbable membrane in conjunction with PDGF and IGF in the dehiscence defects, where it was difficult to maintain space. The use of membrane seemed to be more effective in the inhibition of root resorption.

PURPOSE: We analyzed disease free survival and the prognostic factors of liposarcoma in the extremity. MATERIALS AND METHODS: Between 1994 and 2005, of 44 patients who were diagnosed and treated for liposarcoma of the extremity, 40 patients were restrospectively analysed. 13 out of 40 patients got postoperative radiotherapy. We examined local recurrence, distant metastasis and disease free 5-year survival rate. We also analyzed clinical prognostic factors, such as age, gender, size of tumor, prior unplanned excision, histologic type, surgical excision margin and postoperative radiotherapy respectively. RESULTS: There were 3 cases of local recurrence and 4 cases of distant metastasis. The disease free 5-year survival rate was 85.0%. 26 patients presented with myxoid, 8 well differentiated, 4 round cell, 1 pleomorphic and 1 dedifferentiated histology. The disease free 5-year survival rate of mixoid, well differentiated and round cell liposarcoma were 100.0%, 84.6% and 75.0% (p=0.419). The 5-year disease free survival rate was 90.6% in negative surgical margin (n=25) and 62.5% in positive surgical margin (n=15) (p=0.003). CONCLUSION: Our study suggests that surgical excision margin is significant prognostic factor for 5-year disease free survival rate.

8.Effect of azithromycin on gingival overgrowth of organic transplanted patients.
The Journal of the Korean Academy of Periodontology 1998;28(4):829-836
Management of gingival overgrowth due to medication is bothersome because plaque control measurement alone did not prevent gingival overgrowth. The best treatment of drug induced gingival overgrowth is discontinuing use of the associated drugs. In this report we attempt to evaluate the short term effects of azithromycin which shown to be of some benefit on gingival overgrowth due to medication. We studied 16 organic transplanted patients who had the gingival overgrowth. All patients received oral azithromycin once daily for 5 days. We measured papillary overgrowth index(POI) every interdental areas before treatment and after 2 and 4 week. Severity and frequence of the papillary overgrowth is tend to reduce progressively in 2 to 4 weeks after treatment in all patients. But no case is completely resolved within 4 weeks. We could find the partial resolution of gingival overgrowth with a 5 day treatment of azithromycin. It is not known whether the response to azithromycin was mediated through its antibacterial effect or another mechanism. We suggest that the treatment of azithromycin could be added to periodontal management of patients with gingival overgrowth due to medication.

This study was designed to estimate the prevalence of hepatitis C virus(HCV) infection in drug abusers. The subjects were 141 inpatients who had been admitted to a general hospital with the symptoms and signs of methamphetamine intoxication. Seroprevalence of antibody to the hepatitis C virus(anti-HCV) was 60.3%,(85/141) and it was higher in the group with increased frequency and duration of drug abuse, but such a relationship was not found in the seroprevalence of hepatitis B surface antigen(HBsAg). These findings suggested the possibility of high prevalence of HCV infection in methamphetamine abusers, and the importance of repetitive percutaneous injection in the transmission of HCV infection.
