In order to observe the differences in fixability and stability of the acetabular cup through the differences in cup size in relation to the size of acetabular reaming, we analyzed 75 cases of porous coated acetabular cup of Harris-Galante type which be followed up more that two years. All cases were divided into two group ; the first group (On line fit :45 cases) used with acetabular cup equal in size to the last reaming size and the second group (Press fit : 30 cases) used with acetabular cup 2mm larger than the last reaming size. For initial stability, all cases were fixed with acetabular screws. Both groups were analyzed for presence of gap, change of acetabular inclination, presence of radiolucent line, degree of displacement of vertical distance, stability and clinical results. The results were as follows; 1. The average Harris hip score was improved from 55.8 points preoperatively to 90.2 points postoperatively in the first group, from 56.9 points to 91.2 points in the second group, Clinical results are excellent in 39 cases, good in 4 cases, fair in 2 cases in the first group, and excellent in 29 cases and good in 1 case in the second group. 2. The gap between the acetabular cup and acetabulum was found initially at 17 zones in the first group but no gap at final follow up. In the second group, the gap was found at 23 zones and finally remained less that 1 mm gap was found at 3 cases in zone B1. 3. No radiologic instability of acetabular cup by Martell evaluation was noted in both 1st and 2nd group. Our data suggests that initial gap between acetabular cup and acetabulum in microporous coated acetabular cup were replaced with new bone and also, radiologic stability and good clinical results could be obtained in the second group used with acetabular cup 2 mm larger than the last reaming size.

BACKGROUND: HBsAg carriers are 6-12% of population in Korea. The patients knowledge on hepatitis B and regular follow-up tests are important, because HBsAg carriers have infectivity and the disease may progress without symptoms. We surveyed their knowledge on the hepatitis B and the frequency of follow-up blood test and sonogram. METHODS: From March 1993 through September 1994, 630 patients who were diagnosed as HBsAg positive and Anti-HBs negative in a health promotion center of college hospital were surveyed by mailing questionnaire. The questionnaire included the result of HBV viral marker test, transmission routes, complications, and prevention methods of Hepatitis B, frequency of follow-up test, and doctors recommendation. RESULTS: Of the 490 questionnaires excluded the 140 questionaires returned due to wrong address, 100 were answered, making the reply rate 20.4%. As for the result of HBV marker test, 64% answered their HBV marker as HBsAg positve, 10% answered HBsAg negative, and 26% answered I dont know. 65% answered that they are HBV carrier. As for the mode of transmission, 59% answered that HBV is transmitted by blood, 57% from carrier mother at birth, 29 % by sexual intercourse. 76% of responders know that vaccination is needed for preventing vertical transmission. When making score on their knowledge, significant differences were showed according to education, income and doctors recommendation about regular follow-up test. The number of persons who took regular blood test every 6 to 12 months were 56(56%), and the number of persons who took regular abdominal ultrasonogram were 39(39%). The number of patients who were recommended regular follow-up by doctor was 76%. In this group, 51 persons(67.0%) took regular blood test and 35 persons(35%) took regular sonogram so this frequency is significantly higher than the other group(each 20.8%, 16.7%). CONCLUSIONS: The knowledge on hepatitis B in HBsAg positive patients is relatively low and the frequency of regular follow-up test is significantly higher in the group who took doctors recommendation. So it is very important that HBsAg carriers must be educated about the infectivity, preventive methods, and regular follow-up for early detection of complication like hepatocellular cancer.

Primary germ cell tumor of the testis is rare, which occupies 1 to 2% of all reported malignant male neoplasms. Combined primary germ cell tumor of the testis composed of embryonal carcinoma and seminoma is more rare tumor. The authors experienced a case of 50-year old male who presented with painless enlargement of right testicle. He has had radical orchiectomy and diagnosed by pathologically as combined germ cell tumor of testis. The testicle is measuring 180 gm in weight and 9×6×5 cm in dimension, and almostly replaced by tumor mass. Grossly the tumor is rubbery solid smooth tumor mass, with variegated cut surface with geographically outlined diffuse necrotic area. Histologically the tumor is composed of two components of tumor, which are solid growth pattern of large round to polyhedral cells with clear or granular cytoplasm and distinct cell border, and anastomosing glandular and papillary arrangement of anaplastic epithelial cells. The former corresponds to seminoma, and the latter to embryonal carcinoma. Each tumor lobule is separated by abundant fibrous stroma.

PURPOSE: A survey was performed to identify the level of mouthguard use, awareness, wearability issues and attitude toward mouthguard among elite Korean Taewondo athletes. MATERIALS AND METHODS: Survey questionnaires were given to 152 athletes participating in the Korea National Taekwondo team selection event for the 2010 Guangzhou Asian Games. Questionnaires consisted of three sections, mouthguard awareness, reasons for not wearing mouthguard and the last section to test the level of acceptance on current mouthguard and when the identified problems were resolved. For analyzing difference among response, chi2 test was used and significant level (alpha) was set up as 0.05. RESULTS: Responses in each of items showed significant difference (P<.001). Majority of response regarding each question: Majority of respondents believed that mouthguard were effective in preventing injuries (36.4%) but the result suggested that the provision of information on mouthguard to athletes was inadequate (44.0%) and the result showed that respondents were not greatly interested or concerned in relation to the mandatory mouthguard rule (31.6%). Although the responses on the level of comfort and wearability of mouthguard were negative (34.8%), athletes were positively willing to wear mouthguard if the problems rectified (51.2%). CONCLUSION: Considering the high level of willingness to wear mouthguard if the problems rectified, it is thought that together with efforts in providing more mouthguard information, the work of sports dentistry to research and improve mouthguard will be invaluable in promoting mouthguard to more athletes.
