We observed the effect of application of n-PTFE on mandibular bone defects in the rabbit. GTR is based on the hypothesis that during wound healing, non-osteogenic cells are mechanically blocked from entering a bone defect. This allows the slower-migrating mesenchymal cells from the surrounding bone and marrow, having osteogenic potential, to move the defect site. Bilateral through & through defects, 8mmx4mm in size, involving the inferior border of mandible, were created in the mandible angle of 15 rats. The experimental side was applied with high-density n-PTFE membrane, with the opposite side serving as a control. In the first week of the early experimental period, the bone defects of experimental groups were filled with highly vascularized fibrous connective tissue showing prominent osteoblastic activity with osteoid formation, whereas the defects of control were replaced by dense fibro-muscular tissue without osteoblastlf activity. After 3 weeks, the experimental group revealed well formed bone trabeculae and fibro-vascular marrow within surrounding membrane. With time the amount of new bone was decreased with increase of hematopoietic marrow, and the cortical plate composed of dense mature bone was more thicker. In the whole experimental periods, the inflammation and foreign body reaction were not found around the inserted n-PTFE membrane. After removal of membrane there was marked remodeling of newly formed bone by active osteoclasts in periosteal soft tissue, which decreased the bone volume apparently. These findings suggest that n-PTFE has biocompatibility, flexibility, and rigidity and offer rapid bone regeneration within limited area by the membrane. On the other hand, the early removal of membrane caused reduction of bone volume by the osteoclastic resorption. Thus, the time of removal may be more important factor for maintenance of regenerated bone volume.

PURPOSE: If damage to the neurovascular bundle of the mandibular canal during dental implant surgery of the mandible is to be prevented, accurate measurement of the distance between the alveolar crest and the mandibular canal, as seen on panoramic radiographs, is important. The purpose of this study was to compare the accuracy of panoramic radiography using a lead ruler with that of computed tomography for the measurement of the distance between the alveolar crest and superior border of the mandibular canal and to evaluate the usefulness of panoramic radiography using a lead ruler. MATERIALS AND METHODS: For control study, panoramic radiography of the dry mandible was undertaken using a lead ruler, and computed tomography was added. The distances between the alveolar crest and the superior border of the mandibular canal and between the alveolar crest and the lowest border of the body of the mandible were measured at the level of the 2nd premolar to the 3rd molar. These measurements were compared with actual measurements of the dry mandible in the same areas. The cases of 87 patients[49 men, 38 women; age range, 20 -84 (mean, 42) years] who had undergone panoramic radiography using a lead ruler were reviewed. They were catergorized according to sex, the presence of teeth, and whether under or over 50 years of age. All measurements were compared and analyzed using the Student t-test. RESULTS: Measured values obtained from a panoramic radiograph using a lead ruler(magnification:100.32%+/-5.92) and from a computed tomograph(magnification:100.22%+/-5.55) deviated less from actual measurements on the dry mandible (p > 0.05). The distance from the 2nd premolar to the 3rd molar was greater in male adults (19.62 mm +/-3.95) than in female (17.54 mm +/-4.04) (p < 0.05), except the 3rd molar. In addition, the distance was greater in dentulous patients(18.81 mm +/-3.33) than in edentulous (16.23 mm +/-1.75)(p < 0.05), except the 3rd molar. There was, howerer, no significant difference between patients under and over 50 years of age (p> 0.05), except 2nd pre molar and 1st molar in the female. CONCLUSION: Panoramic radiography using a lead ruler is a simple and accurate modality for the presurgical planning of dental implant surgery. It is suggested that the successful long-term rate of dental implantation may be higher in dentulous male than in edentulous female molars.

BACKGROUND: There were several reports that thyroid autoimrnune disease commonly found in myasthenia gravis patients. We performed this study to determine the prevalence of thyroid autoimmune disease as well as analyze correlation between acetylcholine receptor antibody and various thyroid autoantibadies among the myasthenia gravis patients in Korea. METHOD: The patient group, 48 patients, diagnosed as myasthenia gravis from January 1985 to December 1995 at the department of Neurology, Internal medicine at Dongsan Medical Center was compaired to the control group, 40 patients, with no age and sex difference from the patient group. The samples were collected from both group for the measure of the values of acetylcholine receptor antibody, thyroid autoantibody and thyroid hormones. RESULT: 1) The values of acetylcholine receptor antibody in myasthenia gravis group and control group were 5.78+-0.7nM and 0.05+-0.06nM respectively. Of 48 patients with myasthenia gravis, 38 patients have been measured acetylcholine receptor antibody value > 0.5nM, Their mean average value was 7.24+-0.66nM. 2) The severe myasthenia gravis group with value of acetylcholine receptor antibody 0.5nM and severe myasthenia gravis group with value of acetylcholine receptor antibody 0.5nM showed thyroglobulin antibody value of 159.6+-79.91IU/mL versus 56.86+-32.99IU/mL. also thyroid microsomal antibody value showed 159.0+-79.9IU/mL and 23.633+-0.19IU/mL respectively. 3) Of 48 myasthenia gravis patients, 12 patients (24%) had high value of antithyroglobulin antibody or anti-microsomal antibody and 5 patients (10%) had both antibodies at the same times. In contrast, only 3 patients (8%) were observed with high value of either one of antibodies. Patient with both antibodies was not observed in normal control group. CONCLUSION: According to the datas we have obtained, appearence of the thyroid autoantibody is significantly greater in severe myasthenia gravis group than normal control group. Therefore it is suggested that the prevalence of thyroid autoimmune disease is higher in severe myasthenia gravis group than mild myasthenia gravis group or normal control group.

We report the case of a 67-year-old woman presenting with epigastric pain. Computed tomography identified diffuse phlegmonous esophagitis. Esophagogastroduodenoscopy revealed multiple perforations in the mucosal layer of the esophagus. A large amount of pus was drained internally through the gut. The patient was treated with antibiotics and early jejunostomy feeding. Although phlegmonous esophagitis is a potentially fatal disease, the patient was successfully treated medically with only a minor complication (esophageal stricture).

BACKGROUND AND OBJECTIVES: The Epstein-Barr virus (EBV) is a human herpes virus which causes certain type of lymphoma and some epithelial neoplasm such as undifferentiated nasopharyngeal carcinoma. However, the role of EBV as a causative factor in other head and neck tumor especially, in laryngeal squamous cell carcinoma is not fully elucidated. The aim of this study was to analyze the relationship between the prescence of EBV in laryngeal squamous cell carcinoma and clinicopathologic characteristics. MATERIALS AND METHODS: 65 cases of laryngeal squamous cell carcinoma were retrieved from formalin-fixed, paraffin-embedded blocks and analyzed for EBV by immunohistochemical staining. Results : The EBV was detected in 26(40%) of the 65 patients with laryngeal squamous cell carcinoma and 2(10%) of the 20 control ases. In 26 cases of EBV-positive patients, 13(46.4%) cases were supraglottic cancer and 13(35.1%) cases were glottic cancer. CONCLUSION: These results suggest that EBV may possibly play an etiologic role in the pathogenesis of laryngeal squamous cell carcinoma.

PURPOSE: The education of the patients is an effective component of comprehensive care, especially in patients with epilepsy. We developed an epilepsy educational program designed to improve the knowledge and understanding of the natural clinical course, the treatment, and prognosis of epilepsy. We evaluated the efficacy of this educational program to epilepsy patient's knowledge of their disorder and quality of life. METHODS: We studied 224 patients with epilepsy from Dongsan Epilepsy Center. All patients completed the Knowledge and Quality of Life in Epilepsy-31 (QOLIE-31) questionnaire before a one-day educational program was completed. Six months after the educational program was given, patients completed the same questionnaire. The results of the two surveys were compared. RESULTS: In the initial questionnaire, about 60% of the patients thought that epilepsy is not related with head trauma. About 40% of the patients thought that epilepsy is a genetic disorder. Over 80% of the patients thought that behavior changes are not related to epilepsy. Over 90% of the patients had correct responses about taking antiepileptic drugs. However, only 60% of the patients had their ideas regarding proper social activity correct. After completing the educational course, the results of the follow-up questionnaires were markedly improved concerning the patients' knowledge of epilepsy. In contrast, the quality of life measures changed a little. CONCLUSION: An epilepsy educational program for patients improves their knowledge of epilepsy. This study was performed with only one education workshop, which is not sufficient to improve the quality of life measures. A well-regulated, systematic educational program is needed to efficiently improve the lives of epileptic patients.
