Abstract
AIM: To analyze the clinical features, management, and outcome of treatment of patients with primary intestinal and colonic non-Hodgkin’s lymphoma (PICL).
METHODS: A retrospective study was performed in 37 patients with early-stage PICL who were treated in our hospital from 1958 to 1998. Their clinical features, management, and outcome were assessed. Prognostic factors for survival were analyzed by univariate analysis using the Kaplan-Meier product-limit method and log-rank test.
RESULTS: Twenty-five patients presented with Ann Arbor stage I PICL and 12 with Ann Arbor stage II PICL. Thirty-five patients underwent surgery (including 31 with complete resection), 22 received postoperative chemotherapy or radiotherapy or both. Two patients with rectal tumors underwent biopsy and chemotherapy with or without radiotherapy. The 5- and 10-year overall survival (OS) rates were 51.9% and 44.5%. The corresponding disease-free survival (DFS) rates were 42.4% and 37.7%. In univariate analysis, multiple-modality treatment was associated with a better DFS rate compared to single treatment (P = 0.001). While age, tumor size, tumor site, stage, histology, or extent of surgery were not associated with OS and DFS, use of adjuvant chemotherapy significantly improved DFS (P = 0.031) for the 31 patients who underwent complete resection. Additional radiotherapy combined with chemo-therapy led to a longer survival than chemotherapy alone in six patients with gross residual disease after surgery or biopsy.
CONCLUSION: Combined surgery and chemotherapy is recommended for treatment of patients with PICL. Additional radiotherapy is needed to improve the outcome of patients who have gross residual disease after surgery.

Abstract
OBJECTIVE To assess the prevalence, characteristics and prognostic factors of interstitial lung disease (ILD) in Korean patients with polymyositis (PM), dermatomyositis (DM) and amyopathic dermatomyositis (ADM). METHODS We reviewed the medical records of 72 consecutive PM and DM patients, including six patients with ADM, who were seen at the Rheumatology Clinic of Seoul National University Hospital between 1984 and 2003. RESULTS Twenty-nine PM/DM patients (40.3%) developed ILD. Anti-Jo-1 antibody and arthralgia were associated with the presence of ILD (P = 0.022 and P = 0.041, respectively), whereas dysphagia was more frequently found in patients without ILD (P = 0.041). Lung biopsies revealed diffuse alveolar damage (DAD) (n = 2), usual interstitial pneumonia (UIP) with DAD (n = 2), UIP (n = 1), and non-specific interstitial pneumonia (n = 2). Of the 29 patients, 11 (37.9%) died. The mean survival time in ILD patients was significantly shorter than in those without ILD (13.8+/-1.8 vs 19.2+/-0.9 yr, P = 0.017). Poor survival in ILD patients was associated with a Hamman-Rich-like presentation (P = 0.0000), ADM features (P = 0.0001) and an initial forced vital capacity (FVC) < or =60% (P = 0.024). CONCLUSIONS ILD was observed in 40.3% of Korean PM/DM patients and was associated with poor survival. A Hamman-Rich-like presentation, ADM features and an initial FVC < or =60% were associated with poor survival in ILD.

Abstract
BACKGROUND Adult onset Still's disease (AOSD) is a rare systemic inflammatory disorder of unknown aetiology, frequently accompanying multiple lymphadenopathy. It often mimics malignant lymphoma, and immunohistochemical and molecular studies are needed for definite diagnosis. AIMS To aid in diagnosis and understand the pathogenesis of the disease by clarifying lymph node (LN) pathology in AOSD. METHODS Thirteen biopsies (one follow up biopsy) and medical records of 12 patients were reviewed. Immunohistochemistry, polymerase chain reaction for T cell receptor gamma chain (TCRgamma) and immunoglobulin heavy chain gene rearrangement, and Epstein-Barr virus in situ hybridisation were performed. RESULTS Histologically, LN lesions were classified into four patterns. The most common (six biopsies) showed paracortical hyperplasia, with prominent vascular proliferation, scattered large B/T immunoblasts, and infiltration by reactive lymphocytes and inflammatory cells. In the second pattern (two biopsies), paracortical hyperplasia was accompanied by massive sinus histiocytosis and S-100 positive histiocyte aggregates. The third pattern (three patients) showed an exuberant immunoblastic reaction, in the form of patchy/diffuse infiltration of large T immunoblasts with high mitotic activity, although clonal rearrangement of the TCRgamma gene was not detected. The fourth pattern showed distinct follicular hyperplasia (two cases). One patient with a follow up biopsy showed a pattern change from pronounced follicular hyperplasia to atypical paracortical hyperplasia. CONCLUSIONS AOSD LN lesions show a dynamic histological spectrum, including atypical paracortical hyperplasia, burnt out histiocytic reaction, exuberant immunoblastic reaction, and follicular hyperplasia. During the course of disease, LN reactivity changes and mixed B and T cells are involved in the pathogenesis.

Abstract
We investigated the frequency and distribution of osteopenia according to the clinical severity in ankylosing spondylitis (AS). Bone mass was measured in men with mild (n = 45) and severe AS (n = 31) with dual-energy X-ray absorptiometry (DEXA). Definition of clinical severity was based on the Schober's test. Osteopenia was commonly detected (48% in mild AS and 39% severe AS) and, in mild disease, more frequently observed at the lumbar spine than any of the proximal femur sites. In severe AS, however, the frequency of osteopenia at the femoral neck and Ward's triangle was as high as at the lumbar spine. Both bone mineral density and T-scores in severe disease were lower than in mild disease at the femur neck, Ward's triangle, and total proximal femur, but not in the lumbar spine. The progression of osteopenia may be reflected more reliably at proximal femur sites than at the lumbar spine.

Abstract
Rheumatoid arthritis (RA) is characterized by synovial proliferation and the accumulation of inflammatory cells in the affected joints. Intercellular adhesion molecule-1 (ICAM-1) is readily detected in RA synovial tissues and helps recruit inflammatory cells to the joint. ICAM-1 shows genetic polymorphisms at codons 241 (R241G) and 469 (K469E). In order to investigate the association between ICAM-1 gene polymorphisms and RA, we genotyped ICAM-1 R241G and ICAM-1 K469E polymorphisms in 143 Korean patients with RA, and in 138 healthy controls, by using the polymerase chain reaction-restriction fragment length polymorphism method. No polymorphism of R241G was found in Korean subjects. However, the frequency of the K469 allele was found to be significantly lower in RA patients than in healthy controls. Allele frequency of K469 was lower in RA patient group, compared to that in healthy controls, regardless of the shared epitope status. Distribution of K469E allele frequencies was not different whether the patient had rheumatoid factor, radiographic erosion or extra-articular complications. In conclusion, this study shows lower frequency of the ICAM-1 K469E allele in Korean patients with RA than that in healthy controls.

Abstract
OBJECTIVE We investigated the clinical features of Korean patients with adult-onset ankylosing spondylitis (AAS) and examined the differences between AAS patients with and without peripheral joint disease (PJD). METHODS We studied 67 consecutive patients with primary AAS who visited the rheumatology clinic of a tertiary referral hospital. All patients experienced joint symptoms after the age of 15 and fulfilled the modified New York criteria for ankylosing spondylitis. Hips and shoulders were not considered as peripheral joints. RESULTS The male-to-female ratio was 8.6:1.0. Mean age at disease onset was 22.3 +/- 5.5 (mean +/- s.d.) yr and disease duration was 10.8 +/- 8.0 yr. Spinal symptoms were the first manifestations in 80.6% of patients. During the disease course, hip, shoulder and peripheral joint involvement were found in about 60% of patients. In patients with PJD, the most commonly affected joints were the knees and ankles. The pattern of PJD, in most cases, was asymmetrical and mono/oligoarticular. AAS patients with PJD had fewer spinal symptoms than those without PJD as a presenting feature (71.8 vs 92.9%, P = 0.035). The modified Schober test showed greater increments in patients with PJD (4.9 +/- 2.4 vs 3.0 +/- 2.4 cm, P = 0.002). Forced vital capacity was better in patients with PJD (79.0 +/- 11.4 vs 70.8 +/- 15.5% of predicted value, P = 0.016). Totally ankylosed sacroiliitis, spinal squaring and syndesmophytes on radiographs were less common in the patients with PJD than in those without PJD (33.3 vs 64.2%, P = 0.012; 20.5 vs 67.9%, P = 0.000; and 38.5 vs 71.4%, P = 0.008, respectively). CONCLUSION Peripheral joints as well as shoulder and hip joints were more frequently involved during the disease course in Korean AAS patients compared with earlier reports in Caucasians. The general joint involvement pattern of PJD was similar to patterns reported previously. Our data suggest that, clinically and radiographically, AAS patients with PJD have a less severe spinal disease course than those without PJD.

Abstract
Transforming growth factor-beta1 (TGF-beta1) plays an important role in the pathogenesis of systemic sclerosis (SSc). To investigate the role of TGF-beta1 gene polymorphisms in SSc, we genotyped six biallelic polymorphic positions (position -988, -800, and -509; and codons 10, 25, and 263) in 61 Korean SSc patients and in 148 healthy controls, using polymerase chain reaction-sequence-specific primers. Genetic polymorphisms were found at position -509 and codon 10 in Koreans. The allele frequencies of C/T at position -509 were 0.59/0.41 in patients and 0.56/0.44 in controls. The allele frequencies of C/T at codon 10 were 0.40/0.60 in patients and 0.50/0.50 in controls. In conclusion, no skewed distribution of TGF-beta1 gene polymorphisms was found in Korean patients with SSc.

Abstract
OBJECTIVE The rheumatoid synovium is a hypoxic environment, and hypoxia has been implicated as a factor in the pathogenesis of rheumatoid arthritis (RA). The purpose of this study was to investigate the effect of hypoxia on the expression of matrix metalloproteinase (MMP)-1, -3 and tissue inhibitor of metalloproteinase (TIMP)-1 in rheumatoid synovial fibroblasts. METHODS Synovial fibroblasts obtained from RA patients were cultured for 48 h under normoxic or hypoxic conditions. Assays included western blot analysis and enzyme-linked immunosorbent assay (ELISA) for MMP-1, -3 and TIMP-1, and northern blot analysis to measure TIMP-1 mRNA levels. RESULTS Compared with normoxic culture, hypoxia increased MMP-1 and MMP-3 expression in rheumatoid synovial fibroblasts. Hypoxia decreased TIMP-1 expression in rheumatoid synovial fibroblasts, as measured by both protein and mRNA levels. CONCLUSION These results suggest that microenvironmental conditions, such as hypoxia, may directly contribute to joint destruction in RA by increasing the ratio of MMP-1, -3 to TIMP-1 production in synovial fibroblasts.

Abstract
Radiation synovectomy is a useful treatment modality in patients with refractory synovitis. We have developed a 188Re-tin-colloid as a new radiopharmaceutical agent and investigated its efficacy and safety in patients with rheumatoid arthritis. Radiation synovectomy was performed using 188Re-tin-colloid in 22 knees from 21 rheumatoid arthritis patients refractory to intra-articular corticosteroid injection. The efficacy and safety of administration of 370-1110 MBq of 188Re-tin-colloid were evaluated after 1, 3, 6, 9 and 12 months. Pain intensity on a visual analogue scale decreased significantly 12 months after therapy (mean+/-SD: 68.0+/-26.1 mm vs. 25.1+/-23.4 mm; P=0.0001 by the paired t-test). Pain decreased in 19 cases (86.3%), joint tenderness improved in 14 cases (63.6%) and joint swelling was reduced in all cases (100%). 188Re-tin-colloid was safe. The residual activity of 188Re in the blood was 0.077%+/-0.25% of the injected dose. The radioactivity of 188Re in the urine was 0.14%+/-0.13% of the injected dose. Transient reactive synovitis was observed in 18 cases (81.8%). No clinical side-effects or abnormalities in leucocyte count, platelet count, liver function tests or urine analysis were observed in any patient. In conclusion, in this first study of radiation synovectomy using 188Re-tin-colloid for patients with rheumatoid arthritis, the treatment resulted in the improvement of arthritis and was well tolerated.

Abstract
OBJECTIVE PG201 has been formulated using 12 herbs known to have anti-inflammatory and protective effects on damaged tissue and bone among other functions. The present study was done in order to assess the therapeutic effects of PG201 in collagen-induced arthritis (CIA) in mice. METHODS DBA/1 mice were immunized with bovine type II collagen. After a second collagen immunization, mice were treated with PG201 orally at 10 mg/kg once a day for 18 days. Paws were evaluated macroscopically for redness, swelling and deformities. The levels of TNF-alpha and IL-1beta in the ankle were examined. The severity of arthritis within the knee joints was evaluated by histological assessment of cartilage destruction and pannus formation. Molecular indicators related to CIA pathology were analysed by measuring the serum levels of matrix metalloproteinase 2 (MMP-2), tissue inhibitor of matrix metalloproteinase 2 (TIMP-2) and the anti-inflammatory cytokines interleukin (IL)-4 and IL-10. RESULTS Administration of PG201 significantly suppressed the progression of CIA and inhibited the production of TNF-alpha and IL-1beta in the paws. The erosion of cartilage was dramatically reduced in mouse knees after treatment with PG201. In the serum of PG201-treated mice, the level of TIMP-2 and the ratio of TIMP-2 to MMP-2 were significantly elevated, and the level of IL-4, but not of IL-10, was increased. CONCLUSION Administration of PG201 has therapeutic effects on CIA. Protection of cartilage was particularly prominent. PG201 is a potential therapy for rheumatoid arthritis.

Abstract
OBJECTIVES To identify genes which are more highly expressed in the peripheral blood mononuclear cells (PBMC) of patients with spondyloarthropathy (SpA), rheumatoid arthritis (RA) and psoriatic arthritis (PsA), in comparison to normal subjects. METHODS A 588-gene microarray was used as a screening tool to select a panel of such genes from PBMC of these subjects and of normal subjects. Results were then validated by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS The following genes were more highly expressed in arthritis patients than in normal subjects: macrophage differentiation marker MNDA (myeloid nuclear differentiation antigen), MRP8 and MRP14 (migratory inhibitory factor-related proteins); signalling molecules JAK3 (janus kinase 3) and MAP kinase p38 (mitogen-activated protein kinase); receptors TNFR2/p75, C-C-chemokine receptor type 1 (CCR1), C-X-C-chemokine receptor type 4 (CXCR4) and integrin beta1; and the cytokines/chemokines interleukin (IL) 1beta and IL-8. Expression of CXCR4 was unexpectedly high among all arthritis subjects. Using RT-PCR, ELISA and immunohistology, expression of stromal cell-derived factor 1 (SDF-1) was demonstrated in arthritis joints. CONCLUSIONS The CXCR4/SDF-1 is a potential pro-inflammatory axis for RA, PsA and SpA.

Abstract
Genetic factors and immune dysregulation play important roles in the development of systemic lupus erythematosus (SLE). Tumor necrosis factor receptor 2 (TNFR2) is suggested to be involved in the development of SLE because its genetic locus (1p36) encompasses one of the susceptible loci for SLE and its ligand (TNF) is associated with SLE. To investigate the role of TNFR2 in the pathogenesis of SLE, 139 Korean patients were genotyped with SLE, 137 healthy control subjects were genotyped for TNFR2 196 R/M polymorphism in exon 6 with PCR-SSCP, and the clinical characteristics of SLE were analyzed according to the genotypes. The genotype frequencies of 196 R/R, 196 R/M, and 196 M/M were 3.6%, 30.9%, and 65.5% in SLE patients and 4.4%, 26.3%, and 69.3% in healthy controls (p = 0.676). The allelic frequency of 196 R was 19.1% in SLE patients and 17.5% in healthy controls (p = 0.638, odds ratio = 1.109, and the 95% confidence interval = 0.720-1.708). The clinical characteristics were not different according to the genotypes. In conclusion, no skewed distribution of TNFR2 196 R/M polymorphism was found in Korean patients with SLE compared with healthy controls. Further studies in other populations will be needed to elucidate the role of the TNFR2 polymorphism in the development of SLE.

Abstract
The prevalence of Behcet's disease is the highest in the East Asian and the Mediterranean countries. Behcet's disease is also distributed in the Asian countries, but the nationwide survey has not been performed in Korea yet. The Korean Study Group for Behcet's Disease, founded in 1999, conducted a multicenter, retrospective survey on epidemiologic and clinical features of the patients with Behcet's disease from 20 hospitals around the nation from 1997 to 1999. Of 3,497 patients, 1,527 were classified into complete or incomplete type of Behcet's disease according to the revised Shimizu's classification. The sex ratio was 1:1.75 with the female predominance. Geographical distribution showed the highest frequency in Seoul (38.5%). Clinically, 98.8% had oral ulcers, 83.2% had genital ulcers, 84.3% had skin lesions and 50.9% had ocular lesions. As for the minor clinical manifestations, articular symptoms were the most frequent. The pathergy test showed positive in 15.4% of patients and revealed a higher positive rate in males (20.2%) than in females (12.7%). In conclusion, we performed the first multicenter study on Behcet's disease in Korea and revealed the female predominance, higher frequency of ocular lesions, and lower positivity of pathergy test in the patients.

Abstract
OBJECTIVE Chondrocyte apoptosis has been described in studies of the pathogenesis of various arthritides. Since matrix degradation is important in the pathology of arthritis, we investigated the effect of matrix depletion on chondrocyte apoptosis. METHODS Consecutive 1 mm sections of child's rib cartilage were cultured under 4 sets of conditions: (1) control; and treatment with (2) hyaluronidase, (3) collagenase, (4) hyaluronidase/collagenase alternately. Sections were harvested on Days 5, 8, and 11, and the proportion of apoptotic cells was measured by propidium iodide staining and flow cytometry. Changes of Fas and Fas ligand expression were verified by immunohistochemistry and Western blot. RESULTS Collagenase treatment led to an increase of apoptosis, which began on Day 8, whereas hyaluronidase treatment had no effect on chondrocyte viability up to Day 11. Alternating hyaluronidase and collagenase treatment induced chondrocyte death earlier, but the difference in apoptotic rate was not significant on Days 8 or 11 compared to collagenase treatment alone. Immunohistochemistry showed the expression of Fas ligand in all enzymatically treated specimens. Expression of Fas receptor was ubiquitous in both control and treated specimens. CONCLUSION The collagen framework is important in the maintenance of chondrocyte survival in human cartilage. Upregulation of Fas ligand in matrix depleted specimens suggested that the Fas pathway may have a role in apoptosis induced by matrix depletion.

Abstract
OBJECTIVE To investigate HLA class II associations with systemic sclerosis (SSc) in Koreans according to anti-topoisomerase I (anti-topo I), anti-centromere antibody (ACA), and anti-U1 ribonucleoprotein (RNP) status. METHODS HLA class II alleles (DRB1, DRB5, DQB1) were determined by DNA typing in 200 healthy control subjects and 74 patients with SSc: 35 anti-topo I positive, 3 ACA positive, and 19 anti-U1 RNP positive; among them were 34 diffuse and 40 limited subtypes, and 16 overlap syndrome. RESULTS Anti-topo I positive SSc was strongly associated with DRB1*1502 compared with both controls (23% vs 5%; Pcorr = 0.003) and anti-topo I negative patients (23% vs 3%; p = 0.009); our study confirms observations in Japanese. HLA-DR 67FLEDR71, especially 38V-67FLEDR71 sequence (carried on DRB5*0102 in linkage disequilibrium with DRB1*1502, DRB1*0802, DRBI*1101), showed the strongest association with anti-topo I response (46% vs 16% in controls; Pcorr = 0.001), and 38L-67FLEDR71 group alleles were not associated with anti-topo I response. Anti-topo I response was not significantly associated with HLA-DQB1 alleles in Koreans. There were only 3 ACA positive patients, and all patients had DRB1*1501 and DQB1*0602 as heterozygotes. Anti-U1 RNP occurred at a high frequency (63%) among patients with overlap syndrome, and was not associated with HLA-DR or DQ genes. Among anti-topo I negative patients, diffuse and limited subtypes of SSc were significantly associated with DRB1*0803 (47% vs 15% in controls; Pcorr < 0.05) and DRB1*1501 (50% vs 17% in controls; Pcorr < 0.01), respectively. These HLA associations have not been reported in other ethnic groups and possible associations with certain autoantibody subsets remain to be confirmed. CONCLUSION HLA-DR gene has a primary association with anti-topo I response, and HLA-DR 38V-67FLEDR71 group alleles including DRB5*0102 (in linkage disequilibrium with DRB1*1502) show the strongest association with anti-topo I response in Korean patients with SSc.

Abstract
OBJECTIVE Reactive arthritis (ReA) is postulated to be caused by a defective host defense against gram-negative bacteria. HLA-B27 could play a role in this process, but does not account for the many HLA-B27 negative patients. The objective of this study was to test the expression of 3 macrophage scavenger receptors (SRs) that are responsible for innate immunity against gram-negative bacteria: SR class A type I (SR-AI), SR-AII, and the macrophage receptor with collagenous structure (MARCO). We postulate that defects in such receptors might also contribute to the host risk factors that increase the predisposition to ReA and perhaps other subtypes of spondylarthropathy (SpA). METHODS Peripheral blood, synovial fluid, and synovial tissue samples were obtained from patients with recent Salmonella infection, ReA, other SpA, and rheumatoid arthritis (RA). The expression of SRs receptors was assessed by semiquantitative reverse transcriptase-polymerase chain reaction. RESULTS Evaluation of the peripheral blood mononuclear cells (PBMC) from 4 patients who were recently infected with Salmonella, showed that PBMC from 2 patients who developed ReA expressed positive levels of MARCO, while PBMC from 2 patients who recovered from infection without sequelae did not. The synovial fluid mononuclear cells (SFMC) from some ReA patients expressed MARCO, but the levels were only moderate. The level of MARCO in the SFMC from the SpA patient group was low. In marked contrast, MARCO expression was high in almost all samples of RA SFMC. These findings also extended to synovial tissues. CONCLUSION Expression of the host defense gene MARCO was susceptible to modulation, not only during infections, but also in the inflammatory arthritis conditions RA and SpA. MARCO is a variable to be considered as a candidate factor that might contribute to ReA.

Abstract
High frequency of p16 alteration and high local recurrence rate of bladder cancer make this cancer an ideal target for p16 gene therapy. However, a low transduction rate of p16 via adenoviral vector causes an inconsistent result. In this study, we have tested adenovirus-p16 in several bladder cancer cell lines and investigated a way of improving the low transduction rate. Adenovirus-p16 showed a strong antitumor effect on bladder cancer cell lines (253J and T24) with strong Coxackie-adenoviral receptor (CAR) expression but little antitumor effect on bladder cancer cell lines (J82 and HT1376) with little CAR expression. In this study, we suggest a simple way of overcoming the differential effects of the adenovirus. The addition of butyrate to media was found to increase the transduction rate of adenovirus remarkably and increase the antitumor effect of adenovirus-p16 in bladder cancer cell lines with little CAR expression. Butyrate effects were related with increased CAR expression on the cell surface as well as increased transgene expression from adenoviral vector. From these observations, application of adenovirus-p16 gene therapy with butyrate can overcome the obstacle of low gene transfer and enhance the antitumor effect of adenovirus-p16 in bladder cancer.

Abstract
OBJECTIVE To evaluate the blood concentration of type III procollagen N-terminal propeptide (PIIINP), soluble interleukin-2 receptor (sIL-2R), and von Willebrand factor (vWF) in systemic sclerosis (SSc) patients. METHODS PIIINP, sIL-2R, and vWF were measured in the sera and plasma of 29 SSc patients and 29 sex- and age-matched healthy controls. Serum PIIINP was determined by radioimmunoassay. Both serum sIL-2R and plasma vWF were measured by enzyme-linked immunosorbent assay (ELISA). Associations between concentrations and clinical and laboratory features were evaluated. RESULTS Serum levels of PIIINP and sIL-2R were significantly higher in the SSc group than in the control group (p < 0.01 for both). No differences in serum PIIINP and sIL-2R levels were found between the limited and diffuse cutaneous subsets. However, PIIINP concentrations were significantly higher in anti-Scl-70 positive SSc patients compared with those of anti-Scl-70 negative patients (p = 0.01). Serum PIIINP levels were significantly higher in SSc patients with restrictive pulmonary function (FVC < 80%) than in patients with normal pulmonary function (p < 0.05). The correlation between PIIINP levels and FVC (p < 0.05) was negative, but the correlation between PIIINP levels and modified Rodnan skin scores (p < 0.05) was positive. sIL-2R levels were not correlated with skin and pulmonary involvement of SSc. There was no difference in vWF levels between those of the SSc patients and those of the control groups. CONCLUSION These results suggest that serum PIIINP serves as a biologic marker for the extent of skin and pulmonary involvement in systemic sclerosis. Increased serum levels of sIL-2R in SSc patients support a role for T lymphocyte activation in the pathogenesis of systemic sclerosis.

Abstract
Sjögren's syndrome (SS) is a systemic lymphoproliferative, autoimmune disease, which is characterized by dryness of the eyes, mouth, and other mucous membranes. The nervous system may be affected in up to 20% of the cases of primary or secondary SS. We present a case of a 54-year-old woman with trochlear nerve palsy complicating Sjögren's syndrome secondary to rheumatoid arthritis. We suggest that all patients with multiple cranial neuropathies, especially when associated with rheumatoid arthritis, should be carefully examined for the possible presence of secondary SS.

Abstract
We assessed the prevalence and clinical features of psoriatic arthritis (PsA) in Korean patients with psoriasis. The prevalence of PsA in patients with psoriasis was 9%. Patients with PsA were older and had a longer duration of skin disease than those with psoriasis alone (median age, 40 vs 35 years, P = 0.03, and 15.3 vs 11.7 years, P = 0.04, respectively). Spondylitis was the most common pattern of PsA (50%). Nail change, dactylitis, and enthesopathy were observed in 36%, 15.4%, and 15.6% of patients with PsA, respectively. Increased erythrocyte sedimentation rate (ESR), antinuclear antibody, and radiological sacroiliitis were more frequent in patients with PsA than in those with uncomplicated psoriasis (25.8% vs 10.3%, P = 0.04; 37.9% vs 16.7%, P = 0.02; and 37.8% vs 1.1%, P < 0.01, respectively). The onset ages of psoriasis and arthritis in the spondylitis group were significantly lower than those in the non-spondylitis group (median age, 21.5 vs 31 years, P = 0.03, and 28.5 vs 43.5 years, P = 0.01, respectively). HLA-B27 was prevalent in 8% of patients with PsA.

Abstract
Marfan syndrome (MS) is a dominantly inherited connective tissue disorder characterized by arachnodactyly, tall stature, the presence of aortic aneurysm, and lens dislocation. Takayasu's arteritis (TA) is a chronic vasculitis that primarily affects the aorta and its branches. The authors report the first case of TA in a patient with MS. The simultaneous presence of TA and MS could be a coincidence, however; the pathogenesis of TA might be linked with autoimmunity induced by abnormal extracellular matrix protein derived from the genetic mutations in MS.
