The purpose of this study was to evaluate the characteristics of craniofacial skeleton on orthognathic surgical cases with skeletal Class III malocclusion. For this study, 74 students at the dental college of Chosun University volunteered as a normal occlusion group. They had well-balanced faces and good occlusions with acceptable Class I molar relationship. They had not received orthodontic treatment and had no signs or symptoms of temporomandibular joint dysfunction. 45 malocclusion patients enrolled for orthognathic surgical treatment with skeletal Class III malocclusion at the Department of Orthodontics, College of Dentistry, Chosun University. On the basis of this study, the results of this study were as follows: 1. Skeletal Class III malocclusion was largely due to the overgrowth of mandible in man and the undergrowth of maxilla in woman. 2. The mandible was antero-inferiorly overgrown by large MP-HP angle and large gonial angle in orthognathic surgical cases with skeletal Class Iii malocclusion. And also, upper incisors were severely labioversioned, but on the other hand lower incisors were linguoversioned. 3. In female, lower-third facial height was characteristically shortened in comparison with middle-third facial height and also, lower facial throat angle was sgrall in male.

Thelazia callipaeda, parasitic in the eye of 24 years old Korean male, was extracted from the left eye of the patient in Seoul, Korea. We confirmed that as T. callipeada morphologically, based on the descriptions of Hsu and other literature. We presents the 7th human thelaziasis case in Korea with the historical review of the literature.

We report a caae of hepatic and intestinal infestation with paragonimus wewstermani complicating abscess formation. The pathway by which the paragonimus westermani reaehea liver and intestine is not well understood. However, there was possiblity that it may become lodged in other organs that the lung because of polonged larval migrations through the diaphragm or into various sites in the abdomen. The patient, 52-year-old female gave a history of having reyeatedly consumed raw crabs. An x-ray film of the chest showed clear lunga Skin test for paragonimus-westermani was positive. Abdominal ultrasonogram showed enlargement of the liver with multiple hypoechoic lesiona ERCP revealed multiple ie lesions in the right lobe of the liver. Abdaminal CT showed multifocal abscess cavities with slight rim enhancements. Above meetioned diagnostic procedures suggested liver abscess or hepatoma. Then, an exploratory laparotomy was done for a definite diagnosis, Frozen biopsy, from liver and surgically exe mass from ileocecal region revealed extrpulmonary paragnomiasis involving liver and cecum. Thus, the patient was treated with prasiquantel. Three months later, abdominal ultrasonogram demonstrated slight enlargement of the liver but no evidence of abnormal mass like lesions.

PURPOSE: To determine the magnetic resonance (MR) imaging findings of tuberculous arthritis, and the frequency-in such cases-with which tuberculoma occurs. MATERIALS AND METHODS: MR images of 26 patients (M:F, 14:12; mean age, 46.2 years) with pathologically proven tuberculous arthritis were retrospectively reviewed. The presence of joint effusion, subchondral erosion, synovial proliferation and soft tissue abscess, and whether the inner wall of this abscess was smooth, were assessed. In particular, we determined whether a nodular lesion which showed low SI on T1WI, central low SI with peripheral high SI on T2WI, and rim enhancement on contrast study, was a tuberculoma. RESULTS: The joints involved were those of the knee (n=7), hip (n=7), shoulder (n=4), sacroiliac region (n=3), elbow (n=3), and ankle (n=2). Joint effusion was noted in 15 cases (58%), and subchondral erosion in 24(92%). synovial proliferation was found in 23 cases (88%), and soft tissue abscess in 24 (92%). The inner wall of this abscess was irregular in 17 cases (71%). A tuberculoma was present in intra- or extra-articular soft tissue in 18 cases (69%). CONCLUSION: The MR findings of tuberculous arthritis were subchondral erosion, synovial proliferation, and soft tissue abscess. The presence of a tuberculoma in intra- or extra-articular soft tissue, a specific finding in tuberculous arthritis, was noted in 69% of our cases.

BACKGROUND: Primary hepatocellular carcinoma(HCC) is the second cause of cancer death in our country. Hepatitis B virus(HBV) and hepatitis C virus(HCV) are important risk factors for hepatocellular carcinoma. The mechanism of HCC development and the epidemiology in HCV infected individuals are still unclear. In this study, we investigated the epidemiolgical and clinical features of HCC in relation to viral infection. METHODS: We reviewed the medical records of 160 HCC patients retrspectively who had been admitted to one University Hospital located in Seoul between January 1991 and December 1995. Among these patients, 113 patients were positive for HBsAg(B group), 24 for anti-HCV(C group). We compared epidemiological and clinical data between B group and C guoup. RESULTS: Anti-HCV positivity was significantly higher in HBsAg negative patients than in HBsAg positive patients(53.3:1.7%, p<0.01). The mean age of patients in B group was significantly lower than that in C group(52:62yr, p<0.01). In C group, the proportion of Child-Pugh class B and C was significantly larger than that of B group(35.4: 75.0%, p<0.01). In C group, the proportion of transfusion history was significantly larger than that in B group(4.4: 16.7%, p<0.05), and the proportion of drug abuse hestory was significantly larger than that in B group (31.0:62.5%, p<0.01). In C group, the albumin, cholesterol, Gamma-glutamyl transferase leves were significantly lower than those in B group. In B group, the proportion of metastasis was significantly larger than that in C group(31.9:4.2%, p<0.01). Alpha fetoprotein levels greater than 400ng/ml are much more prevalent in group B significantly(67:39.1%, p<0.05). No significant differences in cumulative survival rate(1yr, 2yr) and median survival time were observed between the two groups. CONCLUSIONS: We ascertain that the HBV and HCV are inportant factors in HCC. In epidemiology and clinical features of HCC, there were some difference between the HBsAg and anti HCV positive group. Therefore, on primary health care settings, it is necessary to test for hepatitis C as well as hepatitis B in order to prevent and manage HCC and chronic liver desease.

The treatment of scar contracture has a relatively long history in the department of plastic surgery. Flap surgery, including Z-plasty and skin graft has been a common surgical modality for the treatment of scar contracture. However, the 'deficiency' of the tissue is basically responsible for the limitations of this treatment. The concept of tissue expansion has contributed to the solution of tissue deficiency and thus tissue expansion is currently widely used for various purposes in plastic and reconstructive surgery. Nevertheless, tissue expansion has not yet clearly solved the problems in cases of seven deficiency of surrounding normal tissues, or in cases of multiple and diffuse scar contracture. We have tried to 'expand the scar tissue' to overcome these limitations. The authors 'several decades of experience in tissue expansion has taught us to find the usefulness of incidentally expanded scar tissues. Thirty-one patients with scar contracture urderwent expansion of surrounding normal and/or scar tissues, including 5 cases of pure scar tissue expansion. The postoperative results were satisfactory with a minimal complication rate. In conclusion, scar tissue expansion was usefully applicable for the scar contracture with no surrounding normal tissues. Scar tissue could be expanded safely and sufficiently, designed to various flaps, and the flap survival was reasonable. The functional and aesthetic quality of the scar tissue seems to improve following tissue expansion. In addition, meticulous planning is essential from the initial operation, including the area of expander insertion, flap design considering the aesthetic unit and functional aspect.
