A case of pigmented villonodular synovitis developed in the right ankle joint is reported. The patient was a 25 years old house wife who had complained marked swelling and tenderness over the anterolateral aspect of the right ankle for 2 years. Roentgenological studies showed marked swelling of the ankle joint and erosion of the neck of the talus. Synovectomy of the affected joint was performed. The tumor mass, measuring about 7cm×5cm×2cm in size, was yellowish brown in colour, elastic and soft in consistency, and contained several well encapsulated nodules.

Systemic lupus erythematosus (SLE) is a multisystemic disease that can involve the gastrointestinal tract, liver, and biliary system. Symptomatic pancreatic involvement, however, has rarely been reported. It may be part of the primary disease process, such as vasculitic or autoimmune etiology, or associated with drug therapy, in particular corticosteroid. We report here a lupus patient who developed severe pancreatitis within 30 hours of initiation of corticosteroid therapy; we also discuss the relation between pancreatitis and systemic lupus erythematosus.

The intravenous administration of midazolam is widely used as sedative premedication for upper gastrointestinal endoscopy. We performed a study to evaluate the effectiveness and safety of midazoiam as premedication for upper gastrointestinal endoscopy. Between June 1995 and October 1995, 112 patients of diagnostic esophago-gastroduodenoseopy were enrolled in the study. The patients were recieved a bolus midazolam 0.~03mg/kg or placebo, followed by typical anesthesia. The blood pressure, pulse and oximeter values were monitored. The systolic blood pressure and heart rate were increased during endoscopy in compared with before premedication, and normalized immediately. There was no significant change of arterial oxygen saturation. Midazolam induced amnesia completely in 49.2% and partially in 27.2%, and all patients were recovered completely in 1 hour. The tolerance score is higher in the midazolam group as compared with the placebo group(p<0.05), and midazolam group would accept the same sedation for repeated endoscopies(p<0.01). We conclude that midazolam has beneficial effects as premedication for upper gastrointastinal endoscopy without significant altteration in cardiopulmonary parameters. This suggest that midazolam may be used more frequently as premedication, especially in the cases of repeated endoscopy.

OBJECTIVE: To evaluate the basophil histamine releasability in response to IgE- and non- IgE-mediated stimuli in children with atopic asthma. Met: Basophil histamine releasability was measured in Dermatophagoides farinae (D. farinae)-sensitive atopic asthmatics, D.farinae-sensitive healthy atopics, non-atopic asthmatics, and healthy non-atopics. Basophils were stimulated with D.farinae, goat antihuman IgE antibody, formyl-Met-Leu-Phe(fMLP), and Calcium ionophore A23187. Histamine was measured by automated fluorometric technique. RESULTS: Sponianeous histamine release was higher in atopic asthmatics compared to healthy non-atopics. Histamine release by D.farinae and by anti-IgE antibody was higher in atopic asthmatics compared to the other groups. There was no difference in histamine release by fMLP among all groups. Histamine release by Calcium ionophore was higher in healthy atopics and non-atopic asthmatics compared to healthy non-atopics. The atopics showed correlation between histamine release by D.farinae, by anti-IgE antibody and total serum IgE levels. CONCLUSIONS: Spontaneous and IgE-mediated histamine release were related to the presence of both atopy and asthma, whereas non-IgE mediated histamine release was different depending on the stimuli.

STATEMENT OF PROBLEM: The Cement as well as restoration required esthetics for making natural color restoration. PURPOSE: The purpose of this research is to evaluate color stability of restoration intermediated by resin cement which is used for cementation of all ceramic crown. MATERIAL AND METHOD: After making Empress 2 ingot into the size of 10mm x 10mm x 1mm according to indication, it glazed and made 48 Empress 2 blocks. Three kinds of resin cement(Rely-X, Variolink 2, Choice) having same shade cemented between Empress 2 blocks and Ivory shade tiles and made 48 specimens in the thickness of 30 micrometer and 80 micrometer. After measureing color difference using spectorphotomenter, the result of this study were as follows. RESULTS: The color difference of resin cement used in experiment increased in the order Rely-X, Variolink 2. As the thickness of cement increases, the color difference of all kinds of cement found statistically sifnificant difference but, this result is clinically acceptable. CONCLUSION: More resarch would have to be done in order to decrease the color difference as cement's thickness.

We investigate the clinical characteristics of Sjogren's syndrome (SS). METHODS: We. retrospectively reviewed 59 patients with SS in the period from January 19: To 86 to January 1997. European Epidemiology Center criteria was used to diagnose SS. OBJECTIVES AND RESULTS: Thirty-one primary SS and 28 secondary SS patients were included in this study. There were 57 females and 2 males, the mean age was 45. 2+12.3 years (24 to 70 years). Patients with secondary SS were associated with rheumatoid arthritis(n=10), systemic lupus erythematosus(n=7), scleroderma(n=5), mixed connective tissue disease(n=3), and myositis(n=3). The common presenting symptoms were dry mouth in 92% and dry eyes in 90% of patients. Other symptom and signs included fatigue(27%), lymphadenopathy(22%) and parotid gland swelling (10%). The commonly presented autoantibodies were antinuclear antibody(83%) and rheumatoid factor(57%). Anti-Ro was positive in 49%(25/51) and anti-La in 37%(19/51). Anti-La positivity was significantly higher in primary SS(52%) compared to secondary SS(21%) (p<0.05). Schirmer test was positive in 98% (44/45), salivary radioscintigraphy in 74%(25/34), and lower lip biopsy in 47%(16/34). Extraglandular manifestations, such as Raynaud's phenomenon, vasculitis, glomerulonephritis, vaginal dryness, renal tubular acidosis, and primary biliary cirrhosis, were more frequently presented in primary SS compared to secondary SS (p<0. 05). CONCLUSION: The sex, age, and clinical manifestation of primary SS were similar with secondary SS, but extraglandular manifestations and anti-La antibody positivity were more frequent in primary SS.

STATEMENT OF PROBLEM: The implant prosthesis has been utilized in various clinical cases thanks to its increase in scientific effective application. The relevant implant therapy should have the high success rate in osseointegration, and the implant prosthesis should last for a long period of time without failure. Resorption of the peri-implant alveolar bone is the most frequent and serious problem in implant prosthesis. Excessive concentration of stress from the occlusal force and biopressure around the implant has been known to be the main cause of the bone destruction. Therefore, to decide the location and angulation of the implant is one of the major considering factors for the stress around the implant fixture to be dispersed in the limit of bio-capacity of load support for the successful and long-lasting clinical result. Yet, the detailed mechanism of this phenomenon is not well understood. To some extent, this is related to the paucity of basic science research. PURPOSE: The purpose of this study is to perform the stress analysis of the implant prosthesis in the partially edentulous mandible according to the different fixture locations and angulations using three dimensional finite element method. MATERIALS AND METHODS: Three 3.75mm standard implants were placed in the area of first and second bicuspids, and first molar in the mandible. Thereafter, implant prostheses were fabricated using UCLA abutments. Five experimental groups were designed as follows: 1) straight placement of three implants, 2) 5.buccal and lingual angulation of straightly aligned three implants, 3) 10.buccal and lingual angulation of straightly aligned three implants, 4) lingual offset placement of three implants, and 5) buccal offset placement of three implants. Average occlusal force with a variation of perpendicular and 30.angulation was applied on the buccal cusp of each implant prosthesis, followed by the measurement of alteration and amount of stress on each configurational implant part and peri-implant bio-structures. The results of this study are extracted from the comparison between the distribution of Von mises stress and the maximum Von mises stress using three dimensional finite element stress analysis for each experimental group. CONCLUSION: The conclusions were as follows: 1. Providing angulations of the fixture did not help in stress dispersion in the restoration of partially edentulous mandible. 2. It is beneficial to place the fixture in a straight vertical direction, since bio-pressure in the peri-implant bone increases when the fixture is implanted in an angle. 3. It is important to select an appropriate prosthodontic material that prevents fractures, since the bio-pressure is concentrated on the prosthodontic structures when the fixture is implanted in an angle. 4. Offset placement of the fixtures is effective in stress dispersion in the restoration of partially edentulous mandible,
