PURPOSE: The aim of this article is to analyze the preference for treatment modality of dentists. MATERIAL AND METHODS: Data of 20,038 patients was involved. Data analysis were done by distribution according to the various kinds of prosthesis, including complete denture, removable partial denture, fixed partial denture, implant-supported dental prosthesis as well as distribution according to the professional titles of the dentists finishing the treatment, including resident and professors. RESULTS: The number of cases of dental prosthesis increased year by year. 61.06% of the patients accepted fixed partial denture restoration. The number of patients who accepted implant supported restoration is also increasing year by year. The number of complete denture, implant-supported dental prosthesis finished by professors was larger than that done by residents, while it was contrary for removable partial denture, fixed partial denture, and the difference was statistically significant (P<.05). CONCLUSION: Professors and residents have some difference in the categorization of prosthesis finished. Fixed partial denture and implant-supported dental prosthesis are preferred.

Ankle arthrodesis has been regarded as a good operative treatment for post traumatic and rheumatoid arthritis of ankle, and ankle arthroplasty has been also developed with several types, from 1970, by Lord & Marotte. Ankle arthroplasty is more functional & less cosmetic troublesome than arthrodesis, and with more developed prosthesis design, more good result will come. The authors operated 6 cases of total ankle arthroplasty for posttraumatic and rheumatoid arthritis of ankle, which were also indications of arthrodesis, and introduce the results and operative problems of ankle arthroplasty.

BACKGROUND: Immunolcgical assays are required for the accurate diagnosis of autoimmune bullous dermatoses including pemphigus vulgaris(PV) and pemphigus foliaceus(PF). In the detection of circulating autoantibodies to pemphigus antigens(desmosomal components), the priority remains controversial between indirect immunofluorescence(IF) and immunoblot(IB) assay. OBJECTIVE: In the present study we compared the sensitivity of indirect IF and that of IB using amplified alkaline phosphatase staining system in the detection of pemphigus autoantibodies. PATIENTS: We selected eight patients with serum endpoint titer of 1:80 in preliminary study. Among these patients three were PV and five were PF. METHODS/RESULTS: The titers of IgG autoantibodies found on indirect IF were confirmed as 1: 80 in all patients, whereas the titers examined by IB assay were much higher, 1: 640 to 1: 2560. In the 3 sera of PV patients, the titers of two cases were 1: 1280 and the third case was 1: 2560. In 5 cases of PF, one was 1:640, two were 1: 1280, and two were 1:2560. CONCLUSION: This result suggests that the immunoblot examination using amplified alkaline phosphatase staining system demonstrates higher sensitivity compared with indirect IF(p=0.0003 by Mann-Whitney U test) in the detection of pemphigus autoantibodies.

Fibrous dysplasia is a benign bony disorder that contains trabeculae of poorly calcified primitive bone formed by osseous metaplasia. It is also characterized by replacement of normal spongiosa by abnormal fibrous tissues. We retrospectively analyzed the computed tomographic (CT) findings of 29 cases with clinically and radiologically diagnosed craniofacial fibrous dysplasia. In 2 cases, only cranial bones were involved and in 7 cases only facial bones were involved. Involvements of both cranial and facial bones were noted in the remained 20 cases. The commonly involved bones in the decreasing order of frequency were as follows: frontal, sphenoidal, ethmoidal and temporal bones in cranium and maxilla, zygoma, lacrimal bones and mandible in facial bones. Even though plain films are enough to diagnose the fibrous dysplasia, we think that CT is useful in more accurate diagnosis by demonstrating amorphous "ground-glass" appearance in the lesion and defining the exact extent of craniofacial fibrous dysplasia.

Kawasaki disease or mucocutaneous lymph node syndrome is an acute inflammatory illness of childhood characterized by systemic panvasculitis. It presents with high fever, dramatic changes of the skin and mucous membranes, and lymphadenopathy. Adult-onset Kawasaki disease is rare and reports on coronary involvement in adult are even rarer. Herein, we report a case of adult-onset Kawasaki disease complicated by splenic infarction and development of coronary aneurysm even despite of treatment with intravenous gamma globulin. A 20-year-old man presented with fever, erytheatous rash, induration and desquamation of hands and feet, pulmonary edema and shock due to cardiomyopathy, splenic infarction, bilateral conjunctivitis, jaundice, and cervical lymphadenopathy. After Kawasaki disease was suspected, intravenous gamma globulin (2 g/kg once) and aspirin (6 g/day) were administered. On the 30th hospital day, transesophageal echocardiography showed one coronary aneurysm and coronary angiography showed three aneurysms. Eight months after the first admission, follow-up coronary angiography showed normalization of the previous coronary abnormalities.

PURPOSE: The aim of this study was to investigate a comparison of implant bone bed preparation with Er,Cr:YSGG laser and conventional drills on the relationship between implant stability quotient (ISQ) values and implant insertion variables. MATERIALS AND METHODS: Forty implants were inserted into two different types of pig rib bone. One group was prepared with conventional drills and a total of 20 implants were inserted into type I and type II bone. The other group was prepared with a Er,Cr:YSGG laser and a total of 20 implants were inserted into type I and type II bone. ISQ, maximum insertion torque, angular momentum, and insertion torque energy values were measured. RESULTS: The mean values for variables were significantly higher in type I bone than in type II bone (P < .01). In type I bone, the ISQ values in the drill group were significantly higher than in the laser group (P < .05). In type II bone, the ISQ values in the laser group were significantly higher than in the drill group (P < .01). In both type I and type II bone, the maximum insertion torque, total energy, and total angular momentum values between the drill and laser groups did not differ significantly (P > or = .05). The ISQ values were correlated with maximum insertion torque (P < .01, r = .731), total energy (P < .01, r = .696), and angular momentum (P < .01, r = .696). CONCLUSION: Within the limitations of this study, the effects of bone bed preparation with Er,Cr:YSGG laser on the relationship between implant stability quotient (ISQ) values and implant insertion variables were comparable to those of drilling.

The purpose of this study is to evaluate the diagnostic accuracy of various quantitative indices for the differentiation of benign from malignant primary soft tissue tumors by FDG-PET. A series of 32 patients with a variety of histologically or clinically confirmed benign (20) or malignant (12) soft tissue lesions were evaluated with emission whole body (5min/bed position) PET after injection of [18F]FDG. Regional 20min transmission scan for the attenuation correction and calculation of SUV was performed in 16 patients (10 benign, 6malignant) followed by dynamic acquisition for 56min. Postinjection transmission scan for the attenuation correction and calculation of SUV was executed in the other 16 patients (10 benign, 6 malignant). The following indices were obtained : the peak and average SUV (pSUV, aSUV) of lesions, tumor-to-background ratio acquired at images of 51 min p.i. (TBR51), tumor-to-background ratio of areas under time-activity curves (TBRarea) and the ratio between the activities of tumor ROI at 51 min p.i. and at the time which background ROI reaches maximum activity on the time-activity curves (T51/Tmax). The pSUV, aSUV, TBR51, and TBRarea, in malignant lesions were significantly higher than those in benign lesions. We set the cut-off values of pSUV, aSUV, TBR51, TBRarea and T51/Tmax for the differentiation of benign and malignant lesions at 3.5, 2.8, 5.1, 4.3 and 1.55, respectively. The sensitivity, specificity and accuracy were 91.7%, 80.0%, 84.4% by pSUV and aSUV, 83.3%, 85.0%, 84.4% by TBR51, 83.3%, 100%, 93.8% by TBRarea and 66.7%, 70.0%, 68.8% by Tsl/Tmax. The time-activity curves did not give additional information compared to SUV or TBR. The one false negative was a case with low-grade fibrosarcoma and all four false positives were cases with inflammatory change on histology. The visual analysis of FDG-PET also detected the metastatic lesions in malignant cases with comparable accuracy. In conclusion, all pSUV, aSUV, TBR51, and TBRarea are useful metabolic semi-quantitative indices with good accuracy for the differentiation of benign from malignant soft-tissue lesions.
