Rheumatoid arthritis is a chronic inflammatory systemic disease of young or middle aged adults, characterized by destructive and proliferative changes in the synovial membrane, periarticular structures, skeletal muscle and perineural sheath. Eventually, the joints are destroyed, ankylosed and deformed. Therfore, the aim of treatment is to keep the inflammatory process at a minimum, thereby preserving the joint motion, maintaining the health of muscle supplying motor power about the joint and preventing secondary joint stiffness and deformity. Surgical treatment in rheumatoid arthritis has progressed and there have been advances in the relief of pain and increase in the range of motion. Among them the results of total knee arthroplasty (TKA) have improved steadily during the past decade due to refinements in design, fixation, and surgical technique. At orthopedic department of seoul national university hospital, we performed 31 total knee replacement in 18 patients who had suffered from rheumatoid arthritis during the period from Aug. 1982 to Dec. 1988. Following results were obtained. 1. Knee score increased from 37.8 to 76.9. 2. Tibio-femoral angle was corrected from 0.9° valgus to 5.3° valgus. 3. Conplications were peroneal nerve palsy in 3 knees, instability in 1 knee, tuberculous arthritis in 1 knee. 4. In 25 out of 31 knees, good functional results were obtained.

BACKGROUND: The appropriate empirical antimicrobial choice in the treatment of community-acquired pneumonia (CAP) should be advocated by community-based information on the etiologic pathogens, their susceptibility to antimicrobials, clinical characteristics and outcomes. Jeju is a geographically isolated and identical region in Korea. However, there is no regional reference on adult CAP available. This study investigated the etiologic agents and clinical outcomes of adult patients diagnosed with CAP in Jeju, Korea, to help guide the empirical antimicrobial choice. METHODS: A prospective observational study for one year in a referral hospital in Jeju, Korea. Patients diagnosed with CAP were enrolled with their clinical characteristics. Microbiological evaluations to identify the etiologic agents in the adult patients with CAP were performed with blood culture, expectorated sputum smear and culture, antibody tests for mycoplasma, chlamydophila, and antigen tests for legionella and pneumococcus. The clinical outcomes of the initial empirical treatment were analyzed. RESULTS: Two hundred and three patients with mean age of 64 and 79 females were enrolled. Ten microbials from 90 cases (44.3%) were isolated and multiple isolates were confirmed in 30. Among the microbial isolates, S. pneumoniae (36.3%) was the most common, followed by M. pneumoniae (23.0%), C. pneumoniae (17.0%), S. aureus (9.6%) and P. aeruginosa (5.9%). The initial treatment failure (23.8%) was related to the isolation of polymicrobial pathogens, elevated inflammatory markers, and the presence of pleural effusion. Among the 30 isolates of S. pneumoniae, 16 (53.3%) were not susceptible to penicillin, and 19 isolates (63.3%) to erythromycin and clarithromycin. However, 29 isolates (96.7%) were susceptible to levofloxacin and ceftriaxone. CONCLUSION:S. pneumoniae, M. pneumoniae, S. aureus, and P. aeruginosa are frequent etiologic agents of adult CAP in Jeju, Korea. The clinical characteristics and antibiotic resistance should be considered when determining the initial empirical antimicrobial choice. Respiratory quinolone or ceftriaxone is recommended as an empirical antimicrobiotic in the treatment of adult CAP in Jeju, Korea.

Upper urinary tract urothelial carcinoma (UTUC) is relatively uncommon. Radical nephroureterectomy with an ipsilateral bladder cuff excision has been the gold standard treatment for UTUC. However, recent advances in technology have made possible the increased use of endoscopic management for the treatment of UTUC. The definitive goal of endoscopic management of UTUC is cancer control while maintaining renal function and the integrity of the urinary tract. Endoscopic management includes both the retrograde ureteroscopic and antegrade percutaneous approaches. The endoscopic management of UTUC is a reasonable alternative for patients with renal insufficiency or a solitary functional kidney, bilateral disease, or a significant comorbidity that precludes radical surgery. Select patients with a functional contralateral kidney who have low-grade, low-stage tumors may also be candidates for endoscopic management. The careful selection of patients is the most important point for the successful endoscopic management of UTUC. It is crucial that patients are compliant and motivated, because a lifetime protocol of strict surveillance is necessary. Adjuvant topical therapy with Bacillus Calmette-Guerin or mitomycin C can be used after endoscopic management of UTUC in an attempt to reduce recurrence. In this article, we review current endoscopic techniques, indications for endoscopic treatment, clinical outcomes of endoscopic management, adjuvant topical therapy, and surveillance in patients with UTUC.

Magnetic resonance image of INFH were correlated with histologic sections. Seventeen patients withe eighteen hips were included in this study. reoperative radiographs and MRI were taken for the patients. Three hips were in stage II, nine hips were in stage III, and remaining six were in stage IV respectively(Ficat and Alert). These hips were replaced with artificial joint and resected heads were examined. The specimens were bisected along the imaging plane, and studied histologically and matched with respective MR images of T1 and T2. Specimen MRI was performed on three femoral head immediately after femoral head removal. Necrotic portion of the femoral head in earlier stage showed higher signal intensity in T1-weighted image. Subchondral void, necrotic bone and saponified fat were responsible for low signal intensity in necrotic portion. Low signal band adjacent to the necrotic foci represented inner fibrous tissue and outer reactive sclerotic bone. Outside the fibrous band, the signal intensity diminished compared with normal fatty marrow. these findings were attributed by cellular infiltration and trabecular bony proliferation. MRI patterns were variable in various stages, but corresponded well with histologic findings.
