The result of forty cases of rheumatoid arthritis according to New York criterion, who underwent multiple operations(up to 10) in multiple joints hetween 1983 and 1986 were evaluated in 3 years and 8 months in average(range; 18 months to 5 years 2 months)postoperatively. The joints operated upon were knee, ankle, shoulder, elbow, wrist and finger joints. The surgery performed were 65 arthroscopic synovectomies, 17 total joint replacement(16 knees and 1 elbow) and 7 arthrodesis(1 knee, 1 ankle and 5 wrists). There were 10 males and 30 females, 27 “clsssic” and 13 “definite” rheumatoid arthritis according to the classification of American Rheumatism Association.Functional capacity of the patient was graded as I, II,III and IV according to the ARA. The final clinical results were graded as “excellent”, “good”, “fair” and “poor” according to the modified citeria of Sledge et al(20). The relationship between number of cases of recurred synovitis and various factors such as sex, classification according to the ARA, number of joints involoved and extent of synovectomy in the knee joint was analyzed statistically with chi-square test of the contingency table.The results are as follows; 1. The final results were 22 “excellent”(55.0%), 16 “good”(40.0%) (altogether 95% of cases were satisfactory) and 2 fair (5.2%), but there was no “poor” result. 2. All cases showed functional improvement, the commonest mode of improvement being from preoperative grade II to postoperative grade I(19 out of 40 cases, 47.5%). 3. There were 9 cases of recurrence of synovitis following arthroscopic synovectomy(22.5 %). They were controlled by medication in 2 cases, and by reoperation in 5 cases (resynovectomy ; 3, joint replacement; 1, arthrodesis ; 1). 4. The factors such as sex, classification and number of joints involved were not significantly correlated c the recurrence rate although there was a tendency of frequent recurrences in cases of female, classic RA and multiple joint involovement (P>0.05). 5. In the knee joint there was significantly less recurrence rate in total synovectomy cases (1/20, S.0%) than in anterior synovectomy cases (7/22, 31.8%) (P<0.01). 6. There was no recurrence following total joint replacment or arthrodesis. In conclusion the combined surgery of arthroscopic synovectomy, joint replacement and arthrodesis in the multiple joints was effective in relief of pain and effusion and improvement of functional capcity of the rheumatoid patient if proper medical treatment was given postoperatively.

PURPOSE: The purpose of this study was to evaluate the diagnostic accuracy of [18F]FDG PET in the diagnosis of recurrent head and neck cancer after the completion of surgery and radiotherapy in patients with head and neck cancers. MATERIALS AND METHODS: In fifty-nine patients with head and neck cancers, whole body [18F]FDG PET studies were performed. According to the different therapeutic modalities, patients were divided into four groups (Group I; pre-treatment, Group II; surgery, Group III; radiotherapy, Group IV; both surgery and radiotherapy). [18F]FDG PET images were compared with clinical, CT and histopathologic findings. RESULTS: For detection of metastatic lymph nodes in 14 patients of pre-treatment group (group I), the sensitivity and specificity of PET were 100% (10/10) and 75% (3/4), and those of CT were 80% (8/10) and 100% (4/4). For detection of recurrence in 45 patients of post-treatment group, overall sensitivity and specificity of PET were 96.2% (25/26) and 78.9% (15/19) [(100% and 75% in group II, 80% and 50% in group III, and 100% and 100% in group IV)] without significant difference from pre-treatment group (p>0.1). In detecting recurrence, the sensitivity and specificity of [18F]FDG PET were 90.9% (10/11) and 20% (1/5) in 16 patients who underwent [18F]FDG PET within 2 months after the completion of treatment. The specificity of these patients was significantly lower than that of 29 patients (100% of sensitivity and specificity) who underwent [18F]FDG PET 2 months after treatment (p<0.05). CONCLUSION: [18F]FDG PET is an accurate diagnostic modality for the detection of recurrence in head and neck cancer. Post-therapy [18F]FDG PET should be obtained at least 2 months after the completion of surgery or radiotherapy.

We describe a 27-year-old man who developed gait disturbance and dysarthria 2 years after the onset of cardinal symptoms of Behcet's disease. Positron emission tomography with 18F-fluorodeoxyglucose revealed severe hypometabolism in the cerebellum, in accordance wih cerebellar symptoms and sign of the patient. However, single-photon emission tomography with Tc-99m-HMPAO and Tc-99m-ECD did not disclose significant perfusion abnormalities in the brain. Routine brain magnetic resonance imaging did not show signal abnormalities. The findings of imaging studies compared with neurological manifestations of the patient are discussed.

Many kinds of membrane have been used for the guided bone regeneration (GBR) technique. However, most membranes do not fulfill all requirements for the ideal membrane for the GBR technique. Among them, collagen membrane has been most widely used. However, its high price and weak tensile strength in wet condition are limitations for wide clinical application. Synthetic polymers have also been used for the GBR technique. Recently, silk based membrane has been considered as a membrane for the GBR technique. Despite many promising preclinical data for use of a silk membrane, clinical data regarding the silk membrane has been limited. However, silk based material has been used clinically as vessel-tie material and an electrospun silk membrane was applied successfully to patients. No adverse effect related to the silk suture has been reported. Considering that silk membrane can be provided to patients at a cheap price, its clinical application should be encouraged.

Tinea pedis is frequently found in those people with poor hygine and in hot and humid environments. The authors investigated the clinical, epidemiologicol a id mycological characteristics of tinea pedis in 138 sewerage workers attending a sewerage plant in Seoul. Tinea pedis was found in 82, with a prevalence of 59.4%. The prevalence of tinea pedis increased with age and the period working at sewerage plant, however, there was no statistical significance. Also there was no difference in the prevalence of tinea pedis between the clerical workers and the field workers. Positive rate for KOH smear was 73.2%, and culture positive rates were 42.7%, producing 35 strains of dermatophytes. Twertyeight strains of Trichophyton Rubrum and 7 strains of Trichophyton mentagrophytes were isolated. Twentyseven yeast-form colonies were isolated, and Trichosporon beigelii was foungl in 19 samples. Most of the yeast forms were found mixed with dermatophytes and moulcis, However, 6 were isolated from direct smear positive cases and yieIded pure colonies of yeast. These included 4 cases of T. beigelii, 1 case of Candida parapsilosis, and 1 case of Candida hormicola. In view of the recent report of these fungi as pathogenic organism, these isolates, rspecially T. beigelii, were considered as a causative agent of tinea pedis in certain groups like sewerage workers.
