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.

Diabetic nephropathy is characterized by one or a combination of the following lesions: (1) glomerular involvement with three distinctive patterns: diffuse glomerulosclerosis, nodular glomerulosclerosis, and exudative lesions; (2) arteriolo sclerosis; (3) urinary tract bacterial infection with pyelonephritis and sometimes emphysematous pyelonephritis. Emphysematous pyelonephritis is an uncommon life-threatening and acute suppurative infection of the kidney, and usually occurs in diabetic female patients. It is characterized by the production of intraparenchymal gas. Glucose fermentation has been considered the main cause of the gas formation. We presented two illustrative nephrectomy cases of emphysematous pyelonephritis in addition to the typical pathologic features of diabetic nephropathy.

PURPOSE: The purpose is to aid in the diagnosis and obstetric management by analysing the ultrasonographic findings of prenatally diagnosed Edward syndrome. METHOD: The study population consisted of 15 cases prenatally diagnosed Edward syndrome from January 1993 to January 1999. The medical charts and ultrasonographic findings were reviewed retrospectively, and especially the ultrasonographic findings before prenatal genetic diagnosis were anlyzed. RESULTS: All of the 15 cases reviewed showed at least one ultrasonographic finding suggesting Edward syndrome. In the first trimester, 2 cases revealed cystic hygroma and increased nuchal translucency, and after the second trimester, major structural anomalies including congenital heart anomalies and minor ultrasonographic findings such as choroid plexus cyst were noted. All of cases after 21 weeks of gestation showed congenital heart anomaly, and as the pregnancy progressed there was an increased tendency of intrauterine growth restriction and polyhydramnios. CONCLUSION: Prenatal ultrasonography in the screening process of Edward syndrome can be placed as a very informative method, as all of the Edward syndrome cases revealed at least one abnormal ultrasonographic findings. As congenital heart anomalies were found in all of the cases after 21 weeks of gestation, fetal echocardiography should be considered in evaluating suspected cases of Edward syndrome.

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.

PURPOSE: To determine the significance of anomalous position of the gallbladder. MATERIALS AND METHODS: Sixteen patients with anomalous position of the gallbladder were evaluated for analysis. The diagnosis was confirmed by ultrasonography(15 patients) and oral cholecystography(1patient). Among those, six patients underwent CT scan and a patient had 99mTc-DISIDA scan. The images were analysed with respect to the location of the GB and configuration and associated abnormality of the liver and hepatobiliary systems. Medical records of each patient were also reviewed. RESULTS: Among 16 patients having an anomalous position of the gallbladder, nine had retrodisplaced gallbladder, four had left-sided gallbaldder, two had suprahepatic gallbladder, and one had floating gallbladder. Except for one patient, fifteen had abnormality in the liver such as focal atrophic or hypoplastic change and liver cirrhosis. Intrahepatic stones were demonstrated in 6 patients. CONCLUSION: Our results showed that anomalous position of the gallbladder was commonly associated with atrophy or hypoplasia of the liver rather than congenital in origin. The possiblity of an anomalous location of gallbladder should be kept in mind when GB is not in its normal location.

Chondroblastoma is a rare primary bone tumor which originates from cartilage, and represents approximate 1% af all bone tumor. The chondroblastoma arises most frequently from the epiphysis of the long bones with the humerus being the commonest site. It afflicts usually the young under 25 years with greater incidence in male. As there is no cartilage cell on craniofacial bone which is mainly fromed by intramembranous ossification, the chondroblastoma on the craniofacial bone is extremely rare. But the chondroblastoma recurred frequently in craniofacial bone when the mass is excised incompletely or curretted and, as the tumor has the outstanding ability of local invasiveness, it destructs the adjacent bone. In addition, it is difficult to diagnose differentially from sarcoma or giant cell tumor histopathologically. Due to the entities described above, it is necessary to remove the entire tumor mass as complete as possible, to treat with radiation pre or postoperatively for preventing from recurrence, and to observe for a long time. The chondroblastoma on temporal bone is rare and is difficult to diagnose and treat successfully. So we'd like to present a case of chondroblastoma which was originated from temporal side of TMJ with literatural review.
