Adenomyomatosis of the gallbladder is Characterized by hyperplastic changes including overgrowth of the mucosa, thickening of the muscle wall, and intramural diverticula, crypts, or sinus tracts(Rokitaasky-Aschoff sinuses). The main diagnostic test for the detection of this disease is oral cholecystography but it's use is being decreased. Recently, Ultrasound, ERCP, and CT have been used for diagnosis. We present a report of case in whom ademomyomatosis of gallbladder was disgnosed on ultrasound and ERCP and confirmed by surgery. The essential feactures of ultrasound and ERCP diagnosis are discussed.

PURPOSE: We reviewed the radiological outcomes and survival rate of the total hip arthroplasty (THA) with AML(R) (Anatomic Medullary Locking, DePuy, Warsaw, IN, USA) hip prosthesis on long-term follow-up. MATERIALS AND METHODS: From May 1988 to December 1990, 93 hip arthroplasties were performed on 77 patients in our hospital. In this study, 30 patients, of whom 41 hips underwent the procedure, were alive and able to be included. Follow-up was average of 21.4 years. The mean patient age was 45 years (35-60 years) at the time of operation. Of the hip procedures included in our study, the reasons for THA were osteonecrosis of the femoral head in 25 hips, rheumatoid arthritis in 3 and acetabular dysplasia in 2. We analyzed the wear rate of the polyethylene, osteolysis of the femur and acetabulum and stress shielding of the femur on the follow-up radiographs. In addition, we investigated the survival rate of the prosthesis and causes of revision in the last follow-up. RESULTS: The polyethylene wear rate of the surviving acetabular cup was 0.15 mm/yr. Acetabular osteolysis was detected in 33 hips and was mostly in zone 2 and 3. Femoral osteolysis was showed in 32 hips in zone 1 and 7. Stress shielding over grade 3 was found in 5 of 21 femoral stems in over 13.5 mm in diameter. The grade of stress shielding did not progress with follow-up. Of the 33 hips, 26 (63.4%) cups were revised for polyethylene wear and osteolysis. There were 6 (21%) femoral stems revised for osteolysis. CONCLUSION: The cause of a high revision rate of the prosthesis was polyethylene wear and osteolysis. We predict that THA using AML(R) prosthesis with wear-resistant bearing surfaces could increase the survival rate on long-term follow-up over 20 years.

OBJECTIVE: In rheumatoid arthritis(RA) patients, HLA-B27 has been mainly found with the same frequency as in the normal population. An increased frequency of HLA-B27 in RA has, however, repeatedly been found in northern Sweden and in Filand. The results concerning the association of HLA-B27 to the outcome of the disease have been contradictory in RA. In RA, the presence of I-ILA-B27 has shown to be a prognostic index for cervical spine subluxation. There has been no report regarding the association between RA and HLA-B27 in the Korean population. METHODS: 188 patients with RA were randomly selected from the patients who were diagnosed at Rheumatism Center of Hanyang University iHospital from October 1994 to June 1995 to establish the frequency of HLA-B27 in RA and to investigate the possible influence and prognostic significance on clinical outcome including atlantoaxial subluxations. RESULTS: The results were as follows: 1) HLA-B27 was present in 12.2% of the RA patients studied. The relative risk(RR) and etiologic fraction(EF) of HLA-B27 were 5.99 and 0. 1019 respectively. 2) The rheumatoid factor was positive in 79.8% of the total patients, 73.9% in HLA-B27 positive patients, and 80.6% in HLA-B27 negative patients. HLA-B27 was not associated with the presence of rheumatoid factor in this study. 3) HLA-B27 was not associated with the duration of morning stiffness, Ritchie index, extraarticular manifestations, the number of swollen joints, ARA functional class, ESR, C-reactive protein, or hemoglobin. HLA-B27 was not associated with the positivity of ANA and antiperinuclear factor. 4) HLA-B27 was not associated with the positive rate of erosion and Steinbrocker class in peripheral joints. 5) Atlantoaxial subluxation was present in 13% of HLA-B27 positive patients and 17% of HLA-B27 negative patients. The involvement of atlantoaxial joint including narrowing of lateral facet joints was 26.1% in HLA-B27 positive patients and 20.6% in HLA-B27 negative patients. Subaxial subluxation was presented in only 1 case in HLA-B27 negative group of total patients. HLA-B27 was not associated with the cervical changes in RA. CONCLUSIONS: An increased freuency of HLA-B27 in RA patients was significantly found in Korea(RR=5.99, EF=0.1019). However, patients with HLA-B27 had a similiar clinical profile to patients without HLA-B27 and HLA-B27 positivity did not further contribute to the severity with respect to clinical and laboratory variables or to radiological progression in peripheral joints or cervical spine.

Herniation of the synovium from the joint space into perioarticular soft tissues is a relatively common complication of adult rheumatoid arthritis, but rare in juvenile rheumatoid arthritis. The most completely described is the popliteal cysts. However, cysts have rarely been reported in the arm. Authors experienced a case of a boy with systemic form of juvenile rheumatoid arthritis who have bicipital synovial cysts in both arm and report this with a review of literature.

OBJECTIVES: To isolate and culture of human muscle cells by manipulating culture conditions. METHODS: Muscle samples were obtained during total hip replacement or bedside muscle biopsy. We isolated myoblasts from freshly obtained human muscle tissue by trypsin and collagenase digesion. RESULTS: Selective isolation of myoblasts was identified through histologic examination by light-microscope. We identified monoc]onal antibodies(Leu-19) as molecular markers in human skeletal muscle were expressed. CONCLUSIONS: This study demonstrated that it had been possible to culture morphologically and immunelogically identifiable myoblasts isolated from human skeletal muscle tissue.

OBJECTIVES: To document the clinical characteristics of Korean male patients with rheumatoid arthritis that are different from those of female counterparts. METHODS: Six hundred and seventy-five patients who had met the ACR criteria for rheumatoid arthritis were included in the study. Clinical and laboratory data were retrospectively reviewed and radiologic features of hands and feet were graded by Steinbroker's method. RESULTS: The female : male ratio in the total patients studied is 567 : 108 (5.25). The symptom onset age was 39.5 +/- 11.8 in woman and 44.0 +/- 11.3 in men. The functional class at the time of diagnosis and the incidence of anemia showed little significant difference. Among the extraarticular manifestations, only interstitial lung disease was more common in males. There were significant differences between both sexes on positivity of antiperinuclear factor, C-reactive protein, and titer of rheumatoid factor in the seropositive groups, but not on rheumatoid factor positivity. Radiologically there was no significant difference in the hands and feet joints between males and females. Higher dosage of steroid was initially prescribed for male patients. CONCLUSIONS: The males seem to have slightly more active disease and to show significant differences in antiperinuclear factor positivity, the titer of rheumatoid factor and C-reactive protein, and lung involvement. However, we failed to demonstrate that the disease in males was more severe than compared to that of their female counterparts.

It's now well recognized that the cervical spine is commonly affected in rheumatoid arthritis(RA) and that subluxation of the atlas is frequently present and may occasionally be fatal. It is not widely appreciated, however, that some rheumatoid patients may develop fractures of the odontoid process in association with relatively minimal trauma or no trauma at all. This is a fracture caused by erosion and osteoporosis of the odontoid process due to rheumatoid synovitis, aging and steroid therapy. In addition, another cause is a dynamic load produced from the instability accompanying atlantoaxial subluxation working on the odontoid in cervical extension. We evaluated a patient with RA who had a fracture of the odontoid process. Following diagnosis she underwent surgery for which the prognosis was excellent.

OBJECTIVES: To investigate the clinical, laboratory and radiological features of psoriatic arthritis. METHODS: Seventeen patients with psoriatic arthritis were studied. The diagnosis of psoriatic arthritis was based on the presence of an inflammatory arthritis associated with psoriasis, usually seronegative. Other rheumatic conditions were excluded. RESULTS: 1) There were 8 men and 9 women(male to female ratio of 1:1.13) and mean age was 41 years old. 2) Thirteen patients developed arthritis an average of 7. 3 years after the onset of psoriasis ; Three had a simultaneous onset of skin and joint disease(within 6 months), while in one patient the arthritis preceded psoriasis by a 10 years. 3) Ten patients had nail lesions, and dactyliris was presented in 6 patients. 4) The frequency of positive rheumatoid factor was 18 percent of the patients, and HLA-B27 was detected in 24 percent. 5) The prevalences of clinical patterns were as follows : oligoarthritis(41.2%), polyarthritis(29.4%), spondyloarthritis(23.5%) and arthritis in distal joint (5.9%). CONCLUSIONS: In contrast to rheumatoid arthritis, psoriatic arthritis occured frequently in males as in females and oligoarthritis was the most common joint pattern.

OBJECTIVES:Nitric Oxide(NO) is a toxic, inorganic, gaseous free radical produced during the metabolism of L-Arginine by NO synthase(NOS). It has been implicated in a rapidly growing number of physiological and pathophysiological processes such as cytotoxic effects against microbes and tumor cells, blood vessel dilation and neurotransmitter. Recently there is growing evidence implicating NO in immune regulation, inflammation, autoimmunity, and arthritis. We performed this study to determine a role for nitric oxide in inflammatory arthritis especially rheumatoid arthritis(RA). METHODS: We measured (1) the concentrations of nitrite, a breakdown product of nitric oxide, in serum and synovial fluid from patients with RA and osteoarthritis(OA) and in the serum of controls (2) the concentrations of nitrite in the supernatant of cultured synovial tissue with RA and OA and (3) determined whether human chondrocytes and synoviocytes can synthesize nitric oxide and if so, how production is regulated by cytokines and antirheumatic drugs. RESULTS: 1) Serum nitrite concentrations in patients with RA and OA were higher than in controls. In both disease groups synovial fluid nitrite was higher than serum nitrite. Serum and synovial fluid nitrite concenrations in RA were higher than those in OA. However, those findings are not statistically significant. 2) Although these findings are not statistically significant, the concentration of nitrite in the supernatant of cultured synavial tissue with RA was higher than that in OA. 3) IL-1beta and TNF-alpah induced the biosynthesis of NO by chondrocytes and synoviocytes. IGF-1 and TGF-beta failed to provoke the production of NO. The biosynthesis of NO required an induction period of approximately 6 hours and was inhibited by L-NMMA and cycloheximide. Dexamethasone, indomethacin, gold sodium thiomalate and methotrexate had no effect on the induction of NO biosynthesis. CONCLUSION: These results suggest a role for nitric oxide as an inflommatory mediator in inflammatory arthritis.

PURPOSE: We assumed that an obese patient has a high rate of postoperative wounds, but there is no objective data showing the relationship between the body mass index (BMI) and the rate of postoperative wounds in Korea. We describe the relationship of BMI and rates of postoperative wound complications. MATERIALS AND METHODS: From September 2005 to February 2006, 772 patients undergoing elective gastrectomy surgery due to gastric cancer were enrolled in a retrospective study to measure postoperative wound complications. A preoperative history, physical examination and daily progress notes were reviewed retrospectively from the medical records. Postoperative wound complications were detected from the elective medical record and from a doctor in charge statement. RESULTS: The total number of patients was 772, the mean age of the patients was 57+/-11.2 years and the sex ratio (male/female) was 1.82:1. Postoperative wound complication rates were different among the BMI groups (BMI<20 kg/m2 vs 20< or =BMI< or =25 kg/m2 vs >25 kg/m2), and patients with a BMI>25 kg/m2 that underwent gastrectomy had a significantly higher wound complication rate (4.6%) than underweight and normal weight patients (0.9% and 1.6%, respectively) (P=0.038). CONCLUSION: Overall, there was a statistical correlation between BMI and the postoperative wound complication rate. Overweight (BMI>25 kg/m2) patients that underwent gastrectomy had a higher wound complication rate than normal body weight (BMI< or =25 kg/m2) patients. Further studies will be required with a larger population and prospectively designed study considering other factors that affect the wound complication rate.
