It is now well-known that the electronic data processing system(EDPS: computer) is very useful for indexing, sorting, verification, and so on. And a few orthopedics in Korea are processing informations with computers for their medical records respeetively. But since there are no established principles on the description of orthopedic diseases, a computer programmer unfamiliar with medical terms is poor in electronic processing for medical records. After processing with an IBM computer for several years, it has come to our attention that we have a need for standardization of the description of orthopedic diseases for EDPS. Based largely on the International Classification of Diseases(ICD-9th), we propose the following: 1. Diseases should be written in English, and whether it be capital letter or small letter does not matter. 2. Description of the disease should be in order of title, region of the body, cause or present status, and side of the body. The sequence may be changed without problem, but only the noun form should be used. It is also recommended that the key words in articles be defined. 3. Abbreviated forms should be avoided. If inevitable, the abbreviation should be used consistently from the first to the 1ast. 4. Connection with other types of medical records such as medical insurance system by registering the code number of the International Classification of Disesaes at the end of the description or on another line.

Many oncogenes and tumor supressor genes have been identified and studied in colorectal carcinoma. Among them, p53 is a tumor supressor gene and its mutation is frequently noted in human tumors. E-cadherin is a cell adhesion molecule and associated with tumor differentiation. CD44 is a cell surface glycoprotein that plays a role in cell migration and metastasis. nm23 is a gene known to lower metastatic potential of tumors and has been proposed to be a metastasis supressor gene. Tumor angiogenesis is required for the expansion of the primary tumor and metastasis and its degree is related to the potential of malignancy. We studied the expression of p53, E-cadherin, nm23, CD44 and tumor angiogenesis in 36 cases of colorectal adenocarcinomas. They were compared with previously known prognostic factors such as the stage, tumor size, depth of invasion, differentiation, presence of lymphatic or venous invasion, the lymph node and distant metastasis. The results were as follows. 1) The expression of p53 was not significantly associated with any prognostic factors. 2) The expression of E-cadherin was significantly associated with tumor differentiation. In the well differentiated adenocarcinomas, its expression was higher than in the poorly differentiated adenocarcinoma. 3) The expression of nm23 was also significantly associated with tumor differentiation. In carcinoma with lymph node metastasis, the expression of nm23 was reduced, but statistically it was not significant. 4) The expression of CD44 was higher in tumors with lymph node metastasis than in tumors without lymph node metastasis, but it was not statistically significant. 5) The degree of microvessel density was significantly associated with lymphatic invasion. According to the above results, the expression of E-cadherin and nm23 are related to the differentiation of the tumor and tumor angiogenesis is related to the lymphatic invasion of the colorectal adenocarcinoma.

Effects of several cytokines(IL -1beta, TNFalpha, and IFNgamma) have been examined on fetal rat osteoblast-like cells. To investigate whether cytokines play direct causal roles in production of lysosomal enzyme, fetal rat osteoblast-like cells were treated with IL-1beta, TNFalpha, and IFNgamma, respectively or combined. And acid phosphatase was determined by biochemical method. Alkaline phosphatase was assayed to determine the effects of IL-1beta, TNFalpha, and IFNgamma on the expression of this enzyme. And also experiment of calcified nodule formation was performed to assess the effects of cytokines on the bone-forming activity of osteoblast-like cells in vitro. Acid phosphatase activity was significantly increased by the addition of IL-1beta and TNFalpha, whereas decreased by IFNgamma, However, no significant changes in alkaline phosphatase activity was observed when the osteoblast-like cells were treated with IL-1beta and TNFalpha. Interestingly, IFNalpha showed stimulatory effect on alkaline phosphatase activity. The number of calcified nodules was decreased by treatment of cultures with 1ng/ml IL -lbeta, 20ng/ml TNFalpha, and 500 u/ml IFNgamma continuously for 21 days, while considerable number of calcified nodules were formed in control group of osteoblast-like cell in culture for 21 days. These results seem to suggest that cytokines may play crucial roles in bone remodeling through the direct action on the osteoblast-like cell.

The distal tibial physes begins its closure about 18 months prior to complete cessation of the tibial growth, closing first in its midportion, then medially, and finally, laterally. So the patterns of the ankle fracture during this period would be different from those of the adult or the children before this period. During the six year period from 1983 to 1988 at the department of orthopedic surgery, college of medi-cine, Hallym University, we found and analysed 54 adolescent patients with the ankle fracture which developed before the closure of the distal tibial growth plate, which were followed up more than 1 year. The results were as follows 1. During the 6 year period of this study, the adolescent ankle fracture comprise 4.4% (54 cases) of all the ankle fractures(1158 cases). Injury occurred more often in male than in female(44 versus 10). The mean age was 13.7 years. 2. The most common cause of injury was traffic accident being in 26 cases(48.1%), the next was slip down accident in 11 cases, and the third was sports activity in 10 cases. 3. The incidence of the adoescent ankle fractures using the Salter-Harris classification revealed 20 (37%) type II, 7 (13%) type III, 5 (9.3%) type IV, and 4 (7.4%) type I and that using the Dias and Tachdjian classification revealed 14 (25.9%) Supination-Inversion, 10 (18.5%) Supination-External rotation, 7 (12.7%) Pronation-Eversion-External rotation, and 1 (1.9%) no adjustable fracture. There were 9 (16.7%) Tillaux and 9 (16.7%) triplane fractures, which were belonged to both classifications 4. The treatments performed were closed reduction and cast immobilization for 28 cases (51.9 %), open reduction and internal fixation for 20 cases (37%), and closed reduction and percutaneous pinning for 6 cases. 5. There were complications experienced in 9 cases, which were 3 premature epiphyseal closure, 3 joint surface incongruity, 2 angular deformity, and 1 leg shortening. 6. For the prevention of the complication, the treatment of the adolecsent ankle fracture should be treated like as adult fracture.

Congenital scoliosis is defined as a lateral curvature of the spine caused by congenital anomalies of the vertebral development. In this study seventeen congenital scoliosis patients seen and treated by either Milwaukee brace or surgical intervention at Department of Orthopedic Surgery, Seoul National University Hospital from December 1972 to April 1978 were evaluated according to frequency of the curve pattern, character of the deformity, method of treatment and its correctability. The following results were obtained in this study. 1. Age distribution was from 2 to 39 years and mean age was 13.4 years. 2. The most common deformity pattern was hemivertebra in 8 cases (47.1%), unilateral unsegmented bar in 4 (23.6%) and mixed type in 3 (17.6%). 3. The most common curve level was thoracic in 6 cases (35.3%), followed by thoracolumbar in 4 (23.5%) and lumbar in 4 (23.5%). 4. The best corrected type by Milwaukee brace was trapezoid vertebra (29.4%) and then mixed type(26.1%), followed by block type (20%) and hemivertebra(2.3%). 5. The operative treatment was performed in the cases of unilateral bar and progressive type with Milwaukee brace. In terms of the correctability of the curvature, the surgical intervention was better than the conservative treatment, with the result of its average correction of 33.5% that is compared with 15.9% of Milwaukee brace. 6. Halofemoral traction was effectively applied in the cases of rigid and severe curve; the initial curve 76.3 degress with 21.3% of flexibility. 7. Loss of correction in operative treatment was 2.3 degrees (6.5%).

Therapeutic irradiation can induce angiosarcoma. Radiation-induced angiosarcoma constitutes 20% of all angiosarcomas. Although its common site of origin is the skin and subcutaneous tissue, it rarely arises in small or large bowels with a presentation as multifocal abdominal angiosarcomatosis. We report a case of intra-abdominal angiosarcomatosis involving the jejunum, ileum, transverse colon, mesentery and right ovary in a 63-year-old female. It developed 10 years after therapeutic irradiation for squamous cell carcinoma of uterine cervix. She developed panperitonitis due to intestinal perforation. She died from sepsis 3 days after segmental resection of the small bowel and right oophorectomy. We reviewed the previously reported cases and describe the clinicopathologic features of this tumor.

The characteristics of modern society's trauma is a propensity for multiple and severe trauma, specially, the fatal damage accompanied by facial bone fracture. We observed the malocclusion owing to delayed prompt treatment If the fractured fragments is crushed severely, it is difficult to make them positioned into the normal anatomical states and to fix them tightly. Post-traumatic malocclusion is usually caused by a delay in treatment and inadequate anatomic reduction. Inadequately treated facial bone fractures result in facial disfiguring and functional impairment of mastication and speech.We performed 27 cases of correction of post-traumatic malocclusion between April 1994 and June 1996. We used various operative techniques such as anterior segmental osteotomy, Le Fort osteotomy, maxillary segmental osteotomy and mandibular sagittal split osteotomy. If the malocclusion was due to disarrangement segmental osteotomy. If that malocclusion was attributed to a malpositioned skeletal bone, we take maxillary segmental osteotomy or mandibular sagittal split osteotomy. We acquired the desirable occlusion first followed by a fixation between the mandible and maxillary skeletal bones with the bite block. The aim in the correction of malocclusion was to create a harmony of centric relation and centric occlusion. After operation, intermaxillary fixation with bite block have many advantages in the treatment of malocclusion.

The T cell responses to hepatitis B surface antigen (HBsAg) were analyzed in acute hepatitis patients, chronic active hepatitis (CAH) patients and asymptomatic carriers. Neither proliferative responses nor substantial cytokine production of peripheral blood mononuclear cells (PBMC) in response to HBsAg was detected. For further studies, HBsAg- reactive T cell lines were prepared from PBMC of the hepatitis patients and asymptomatic carriers. No proliferative response of the T cell lines was observed. Interestingly, however, T cell lines obtained from acute hepatitis patients were found to produce IFN-r, but not IL- 4, in response to HBsAg stimulation, whereas T cell lines obtained from CAH patients and carriers were not. Results of this study suggest that HBsAg-reactive T cells producing Thl type cytokines may play an important role in the viral clearance during acute infections, while defects in those T cells may be responsible for the viral persistency.

OBJECTIVE: The purpose of this study was to evaluate the motor recovery of initial and plateau period in the patients with subcortical stroke lesion which were different locations. METHOD: We studied the 42 stroke patients with subcortical lesions who had been admitted to the Department of Rehabilitation Medicine from 1998 to 2000, retrospectively. Patients were divided into four groups according to the information from brain CT or MRI; Group 1: basal ganglia, group 2: anterior limb of internal capsule and/or basal ganglia, group 3: posterior limb of internal capsule and/or basal ganglia and group 4: thalamus only. Quantitative assessments of motor recovery using the Brunnstrom stage and results were correlated with sites of lesion. RESULTS: 1) Brunnstrom stages at initial and plateau period were the highest in the patients with thalamic lesion and the lowest in the patients with posterior limb of internal capsule and/or basal ganglia lesion. The patients with thalamic lesion showed higher stage than the patients with basal ganglia with anterior limb lesion in hand and low extremity (p<0.05). 2) Significant motor recovery was occurred in all patients except the lesion located in thalamus (p<0.05). CONCLUSION: There were significant differences of motor recovery at plateau period in the patients with thalamic lesions comparing with basal ganglia with anterior limb lesion about hands and lower extremities and patients with basal ganglia and/or capsular lesion showed good motor recovery.
