Nonpancreatic pseudocyst is a rare lesion, with a specific fat-fluid level in the cyst. It is found among all age groups. The condition has been previously reported in foreign but not in domestic journals; we now describe one such case.

OBJECTIVE: Vascular endothelial growth factor (VEGF),a potent angiogenic, permeability-enhancing cytokine plays an important role in chronic inflammatory process of rheumatoid arthritis (RA).Nonsteroidal anti-inflammatory drugs (NSAIDs)are the most widely used drugs for the treatment of RA.However, the effect of NSAIDs on angiogenesis in rheumatoid synovium is unclear.In this study,we investigated the effects of NSAIDs such as indomethacin (IDC) on TGF-beta-induced VEGF production in rheumatoid synoviocytes. METHODS: Fibroblast-like synoviocytes (FLS)from RA were stimulated with T G F -beta(10 ng/ml)for 24hr in the presence of the various concentrations of IDC. The levels of VEGF were measured in culture supernatant by ELISA.In addition, COX-2 and VEGF mRNA expression of cultured FLS were evaluated by RT-PCR. RESULTS:VEGF production from FLS was significantly increased in the presence of TGF-beta.IDC exerted a dose-dependent inhibitory effect on the production of VEGF induced by TGF-beta.RT-PCR analysis showed that IDC also inhibited TGF-beta-induced COX-2 and VEGF mRNA expression in cultured FLS by a dose-dependent manner. CONCLUSION:Our results demonstrate that NSAIDs inhibit VEGF production and the expression of its mRNA and COX-2 mRNA in synovial cells of RA patients.These findings suggest that NSAIDs may suppress progression and perpetuation of rheumatoid synovitis by anti-angiogenic activity.

PURPOSE: To evaluate the usefulness of percutaneous management and prognosis in venous rupture during angioplasty of hemodialytic arteriovenous fistulas. MATERIALS AND METHODS: Among 814 patients who underwent angioplasty on account of inadequate hemodialysis, 63[39 women and 24 men aged 20-78 (mean, 55.8) years] were included in this study. All 63 had peripheral venous stenosis. Venous rupture was diagnosed when contrast leakage was seen at venography after percutaneous angioplasty (PTA). In order to manage venous rupture, the sites at which this occurred were compressed manually for 3-5 minutes or blood flow was blocked with a balloon catheter for the same period. In one case, a stent was inserted at the rupture site. Using the Kaplan-Meier method, we investigated the patency rate of arteriovenous fistula (AVF) in cases of successful PTA. We also compared PTA patency rates in cases with and without peripheral venous rupture. RESULTS: Venous rupture occurred in 38 cephalic, 16 brachial, and 9 basilic veins. In 63 patients, bleeding stopped and in 54 (85.7%) of these, PTA was successful. Among the nine failed cases, dilatation was incomplete in five, though bleeding had stopped. In patients with brachial and cephalic vein rupture, the venous tract at the rupture site was not located. Two patients underwent surgery: one of these experienced brachial venous rupture, with incontrollable bleeding, and the other had nerve compression symptoms due to hematoma. Among 54 patients in whom PTA was successful, the primary and secondary six-month rates for angioaccess were 47.9% and 81.2%, and the mean patency period was 6.1 and 15.8 months, respectively. In cases of non-venous rupture, the mean patency period was 9.6 months, significantly longer than in cases involving venous rupture (p=0.02). CONCLUSION: Venous rupture occurring during the PTA of hemodialytic AVF can be managed percutaneously.

OBJECTIVE: To evaluate clinical significance of interleukin 15 (IL-15) in patients with Behcet's disease (BD). METHODS: Serum samples were obtained from 31 patients with BD and 29 healthy controls. BD patients were divided into active and inactive group according to the presence of clinical manifestations on the day of sampling. Serum levels of IL-15 and IL-8 were measured by sandwich enzyme-linked immunosorbent assay (ELISA). RESULTS: Serum levels of IL-15 and IL-8 were significantly higher in BD patients than in healthy controls (117.2+/-26.2 pg/ml versus 51.8+/-15.4 pg/ml, p<0.01, 287.7+/-100.9 pg/ml versus 138.5+/-17.2 pg/ml, p<0.01, respectively). There was a significant correlation between serum levels of IL-15 and IL-8 IL-15 levels compared with those without it (161.1+/-68.8 pg/ml versus 96.4+/-3 4 . 8pg/ml, p<0.05). Serum levels of IL-15 and IL-8 tended to be higher in active group than in inactive group, but didn't reach statistical significance. CONCLUSION: Serum level of IL-15 was elevated in patients with BD, especially those with uveitis, but it did not seem to be useful as a marker of disease activity in BD.
