In spite of the progress in techniques and materials of the prosthodontic rehabilitation of patients with complete edentulous arches, prosthodontists still face patients' complaints about dissatisfaction and discomfort from their dentures. In the past several decades, prosthodontists tried to find the factors that influence the patient's satisfaction with dentures. However the results are contraversial especially with the psychological factor. In this study using patient denture satisfaction questionnaire' and Hopkins Symptom Checklist, we tried to find the correlation between the patient's denture satisfaction and the patient's psychological aspects. 23 complete edentulous patients who have visited the Department of Prosthodontics, Yonsei University Dental Hospital from September 1998 to June 1999 for complete denture treatment were asked to complete the questionnaires 4 to 6 weeks after the upper and lower complete delivery. After the measurement of validity of the questionnaires, correlations between the patient's general satisfaction with their new upper and lower complete dentures and the other satisfaction questions including the satisfactions with esthetics, retention, mastication, speech, comfort and other peoples's opinion and between the patient's general satisfaction with their new upper and lower complete dentures and the 5 symptoms of Hopkins Symptoms Checklist including somatic, obsessivecompulsive, interpersonal sensitivity, depression and anxiety were analyzed. Among the several satisfaction questionnaire items, comfort with the lower denture showed highest relation to the patient's general satisfaction with dentures. However, only the anxiety scale of Hopkins Symptom Checklist among the other symptom scales was related to the patient's general satisfaction with dentures. The two questionaires used in this study turned out to be valid means of analyzing patient's denture satisfaction and psychological status before and after the complete denture treatment.

It has been increasingly clear that the defence against Mycobacterium leprae(M. leprae) appears mainly to depend on cell-mediated rather than humoral immune mechanism. Nevertheless, the M. leprae is not only capable of producing specific humoral antibody, but also stimulating the formation of a variety of autoantibodies, since mycobacteria are known to exert adjuvant effect. Although the exact role of the autoantibodies in the pathogenesis of leprosy is not known, it is remarkable that the prevalence of autoantibodies has been reported different by several investigators, suggesting the possibility of geographical or racial difference. This study was undertaken to investigate the prevalence of some autoantibodies in Korean patients with leprosy. Eighty patients with leprosy registered at the Department of Dermatology, Seoul National University Hospital entered this study from February, 1977 through October, 1978, The diagnosis was made by clinical, histological, bacteriological and immunological assessments and the patients were classified according to the Ridley-Jopling scale. All patients were under anti leprosy chemotherapy with DDS (Diaminodiphenylsulfone) for various periods at the time of study. Venereal Disease Research Laboratory (VDRL) test was performed in 80 patients and the sera displaying reactive VDRL were subjected to re-examination by Treponema Pallidum Hemagglutinin Assay (TPHA). Rbeumatoid factor was sought by means of latex fixation test in 66 patients. Antinuclear antibody (ANA) was detected by means of latex agglutination reaction in 61 patients using polysterene latex complexed with calf thymus deoxyribonucleoprotein. Cryoprotein was detected as described elsewhere. Four of the 80 patients(5%) showed reactive VDRL, while rheumatoid factor and antinuclear antibody were not detectable in all cases. Cryoprotein was detected in 15 patients (27. 3 %). Compared with other reports on the prevalence of autoantibodies in Caucacian and African patients, we found a much lower frequency. This result may be expained partly by the racial or geographic difference in the pattern of leprosy as suggeste4 by Turk.

Dermabrasion involves the removal of the epidermis and the upper dermis by means of a motor-driven rotary abrasive instrument or a brush using ethyl chloride or dichlorotetrafluoroethane(Freon) as the evaporative refrigerant-anesthetic. Kurtin(1952) developed this refrigeration-abrasion method and named it skin planing. The technique of skin planing was introduced to Korea in early 1960s and it was extensively used for corrective surgery of scar induced by small pox until early 1970s. The indication for dermabrasion includes correction of scars, prophylaxis and correction of aging of the skin, removal of congenital nevoid anomalies, malignant and benign skin tumors, tattoos and others. The authors dermabased the cutaneous lesions of xeroderma pigmentosum, angiofibroma (adenoma sebaseum), nevus sebaceus of Jadassohn, epidermal verrucous nevus and linear porokeratosis, using Stryker' pneumatic powered dermabrader, with successful results. The technique of dermabrasion and the literature were briefly reviewed.

The Schatzki ring, a submucosal fibrotic thickening of the lower esophagus, occurs at the squamocolumnar junction and is invariably associated with an esophageal histal hernia The ring is discrete narrowing covered with squamous epithelium on its superior aspect and columnar epithelium on its inferior aspect, with various degrees of submucosal fibrosis supporting the annulair ring. Symptoms, when present, are generally those of distal esophageal obstruction to the passage of solids and highly associated with ring diameter. The pathogenesis and etlology are obscure. But one theory suggests that they are caused by gastroesophageal reflux. The vast maiority of symptomatic Schatzki rings sre ameneble to dilation, a few patients will require surgical antireflux measures after dilatation. We have experienced a case of Schatzki ring associated with reflux esophagitis and esophageal hiatal hernia by the esophagogram after barium swallowing and endoscopy. So we report this case with brief review of the previous literatures.

Benzoyl peroxide has been known to have bacteriostatic activity against Corynebacterium acnes and to have comedolytic action in patients with acne vulgaris. The present study was undertaken to evaluate the therapeutic effect of Renoxal, a 5% benzoyl peroxide lotion, in patients with acne vulgaris. A total of 35 patients entered this study at the Department of Dermatology, Seoul National University Hospital during the five months period from March to July, 1978. All patients were instructed to apply Benoxal on their affected sites once or twice daily; and the number of lesions on three fixed areas were counted before and every week for four weeks after the treatrnent. Two female patients stopped the application due to developrnent of contact dermatitis to Benoxal The results observed in the 33 patients were as follows: 1. The percentage decrease in total number of lesions in four weeks after treatment was 51.1% 2. Closed and open comedones were gradually eliminated; and their numbers were decreased in four weeks after treatment by 45. 8% and 55. 3% respectively. The papules were decreased. by 59. 1 @2 after the first week of treatment, but showed. a transient lag around tbe second week and then marked 61. 5% in four weeks after treatment. 3. Observed side effects included burning sensation,(3 cases), tightness (3 cases), itching sensation (2 cases) and scaling (1 case). All were tolerable without any specific measure or discontinuance of the application. The authors concluded througb this experiment that Benoxal (5% benzoyl peroxide lotion) is a very effective local therapeutic agent in the treatment of acne vulgaris patients.

Most of the malignant tumors of the pancreas are adenocarcinomas arising from the ductal epithelium. Primary leiomyosarcoma of the pancreas, even though it is the most common sarcoma of the pancreas, is very rare. We present a case of leiomyosarcoma of the pancreas, probably primary, with metastases to the stomach, lymph nodes, and abdominal wall. A 52-year-old woman visited the hospital with vague right upper abdominal pain and weigh loss of 6 kg for 2 months. The radiological and endoscopic examination revealed that she had a large heterogeneous mass, 11 cm in size, in the pancreatic body and tail, a 4 cm-sized mass in the paraaortic area, and a 3 cm-sized polypoid mass in the stomach. Histologically, they were all similar to one another and composed of markedly pleomorphic cells. Immunohistochemical and electron microscopic studies showed definite smooth muscle differentiation of the tumor cells. Two months later, the patient underwent an excision of a new 3 cm mass in the right lower abdominal wall, showing features of well differentiated leiomyosarcoma.

STATEMENT OF PROBLEM: In spite of the progress in techniques and materials in complete denture prosthodontics, patients still complain of discomfort after the insertion of complete dentures. For the last several decades many prosthodontists tried to find factors influencing patient complete denture satisfaction, however the reported results became a controversy. PURPOSE: The purpose of the present study was to verify the factors influencing patient satisfaction with complete dentures using multiple regression analysis. MATERIALS AND METHODS: 33 patients who visited the department of prosthodontics, dental hospital of Yonsei University, 4 to 6 weeks after the complete denture delivery, were asked to complete the questionnaires on complete denture satisfaction, social variables and psychological variables. The Prosthodontists who treated the patients with complete dentures were also asked to complete the questionnaires on evaluation of patients' oral condition and technical quality of dentures. The factors influencing patients' satisfaction with their complete dentures were analyzed using multiple regression analysis. RESULTS: Among the patients' sociodemographic variables, the variables of relationship with children, economic status, housing condition, other people's opinions of dentures and gender were the influential factors on patients' satisfaction with complete dentures. Patients showing the symptoms of depression, one of the psychological variables, were dissatisfied with their complete dentures. In spite of the good oral condition, patients were dissatisfied with complete dentures, whereas the technical quality of dentures did not influence patients' complete denture satisfaction. CONCLUSION: According to the results above, patients' sociodemographic and psychological variables rather than clinical variables including oral condition and technical quality of dentures were the influential factors on complete denture satisfaction. The results of this study may not only enable prosthodontists to predict the success and failure of complete denture treatment, but also help both prosthodontists and patients be informed of the essentials of increasing satisfaction with complete dentures.
