Clinical study of 40 cases who have used steroid preparations was done during past 6 months from March 72 to September 72. 1. The youngest patient was twenty, the oldest seventy-four and the average fifty-two. Eighty percent was included between from 41 to 70 year of age. 2. And the sex ratio was 1:4.7. 3. Diagnostic incidence was 47.5% in degenerative arthritis and 40% in rheumatoid arthritis. 4. The causes of administration were multiple joint pain (35%), lumbago (27.5%) and pain on knee joint (25%) in order. 5. Prednisolone (60%), dexacortisil (25%) and dexamethasone (12.5%) were used in 97.5%. 6. The source of steroid was drung store (95%) or doctor (5%). 7. The time from first dose to last dose was less than 1month (20%), 1–3 month(10%), 4–6 month (7.5%) and more than 1 year (52.5%). And 3 cases have used for more than 5 years, 8. Eighteen cases (45%) used steroid continuously and 22 cases (55%) irregularly. 9. Transient effectiveness was experienced in 92.5% with steroid administration, that was one of the causes of steroid usage without doctor's prescription. 10. The side effects were as follows; moon face (62.5%), ulcer (20%), fat deposition (15%), osteoporosis (15%), peripheral edema (10%), elevation of blood pressure (7.5%), malar flush(7.5%), vertebral compression fracture (7.5%), obesity (5%), psychotic change (5%), pyogenic arthritis (5%), diabetes (2.5%), sepsis (2.5%), adrenal insufficiency (2.5%), avascular necrosis (2.5%) and stress fracture of femur neck (2.5%).

Failure of total joint replacement is often due to infection. Many efforts have been made to reduce the rate of infection. The use of antibiotic-acrylic bone cement composites for the preventlon and treatment of infection after joint replacement surgery has been advocated. Early reports of clinical success using bone cement containing antibiotics are encouraging, but different results of antibacterial effect of antibiotic-acrylic bone cement were reported in vitro and in vivo studies. The purpose of this experiment is to determine the effectiveness of bone cement itself on bacterial growth, stability of antibiotics in cured bone cement, and whether antibiotic acrylic bone cement composites produce an effective antimicrobial concentration in tissue fluid of hip joint and if so, the duration of it. 30 rabbits were used as test animal: 3 each for hemiarthroplasty and for hemiarthroplasty with the insertion of bone cement as control; 6 each for dicloxacillin, cephacetrile, gentamycin and amlkacin impregnated bone cements. Antibiotic activities were measured by disk diffusion method and tube dilution method using tissue fluid collected through tube inserted in the hip joint of the animals. The results were as follows: 1. Bone cement itself does not have antibacterial effec: on the growth of Staphyiococcus aureus and Escherichia coli. Antibiotic impregnated acrylic bone cements showed antibacterial effects which were stable for 3 weeks in vitro test. 2. After the insertion of antibiotic-acrylic bone cement composites, maximal concentrations of antibiotics in tissue fluid were measured at 1 hour. The concentration of antibiotics remained in tissue fluid at relatively high level for 2 days, and decreased abruptly there after. Inhibition zones in disk diffusion method could be measured until 3rd day in dicloxacillin group and 4th day in cephacetrile, gentamycin and amikacin group. No antibacterial effect could be measured in control groups. 3. On first postoperative day the concentrations of antibiotics in tissue fluid were measured as 64 mcg/ml in dicloxacillin group and 128 mcg/ml in cephacetrille, gentamycin and amikacin group. The antiblotic activities in tissue fluid could be measured for 6 days in dicloxacillin group and 7 days in cephacetrile, gentamycin and amikacin group using tube dilution method. No antibiotic activities were measured in tissue fluid of control groups. As a result of this study, it is proved that the concentration of antibiotics in tissue fluid of hip joint can be maintained above the level of minimal inhibitory concentration for about a week when antibiotic-acrylic bone cement composite is used in joint replacement arthroplasty. The impregnation of antibiotics in crylic bone cement is proved to be effective in the prevention of exogenous infection, especially in the protection of damaged tissue prone to infection postoperatively.

OBJECTIVE: Endometriosis is a disease affecting a large population of women all over the world. A local sterile inflammation occurs in the peritonel cavity of patients with endometriosis. It suggests that immunological events play a major role in the pathogenesis of endometriosis. We have studied the levels of serveral T cell and monocyte derived cytokines, especially IL-6 (promoter of immune response) and IL-10 (inhibitor of immune response), in the peritoneal fluid of patients with endometriosis to characterize the change of immune response that occurs at the site of endometriosis. Method: This study was performed in Hallym university hospital from October, 1997 to October 1998 and enrolled 29 women with gross or microscopic findings of minimal to severe endometriosis in case group, and 28 women without visual evidence of pelvic endometriosis and with benign gynecologic disease in control group. IL-6 and IL-10 levels in the peritoneal fluid were determined using commercial ELISA and compared between endometriosis and controls and between fertile and infertile women with endometriosis and according to the revised American Fertility Society classification. RESULT: IL-6 was higher and IL-10 was lower in the peritoneal fluid of endometriosis group than of control group. Cyclic variations in the IL-6 concentrations were seen in endometriosis group : the concentrations in the secretory phase were significantly higher than those in the proliferative phase. In endometriosis group, IL-6 concentrations of infertile women were higher than fertile women. Both IL-6 and IL-10 in the peritoneal fluid of endomtriosis group did not show significant correlation according to r-AFS stages. CONCLUSION: Increased IL-6 and decreased IL-10 levels in the peritoneal fluid may be related to infertility and pathogenesis in the endometriosis, suggesting that partially contribute to the disturbed immune regulation observed in endometriosis.

As the number of primary total knee arthroplasties (TKA) have increased, there has been a corresponding increase in the number of revision TKAs. The purpose of the this study is to report on the follow-up results of 50 revision TKAs, and to assess their clinical outcome. From January 1990 to December 1995, 50 revision TKAs were perfomed in 43 patients, by one surgeon. Mean follow up time was 2.5 years (range, 1 to 6 years). The mean interval from the initial arthroplasty to revision was 4.6 years (range, 3 months-12.6 years). The causes of the revision were wear of polyethylene in 29 joints (58%), infection in seven (14%) and aseptic loosening in six. The revision components were fixed with cement in all cases. Additional fixations were obtained with modular stems (femoral 11 cases, tibial 13 cases), 9 tibial metal wedges, 7 femoral augmentations, and 12 allografts. The Knee Rating Scale of Hospital for Special Surgery was used for clinical assessment. The mean flexion contracture and further flexion of knee joint were 8.8degrees (range, 0-70degrees), 98.5degrees (range, 5-135degrees) preoperatively, and 3.7degrees (range, 0-15degrees), 112degrees (range, 75-135degrees) postoperatively. The Knee Rating Scale improved from 66.5 points (range, 15-83) to 87.5 points (range, 79-98). There were two cases of complications, dislocation of patella and superficial wound problem in each case. In conclusion, wear was the most common cause of failure of primary TKA. The results of revision in infected TKA were less favorable than that of wear and loosening. The prosthetic design and thickness of polyethylene were the most important factors related to wear. The tibial component of PCA and patellar component of Miller-Galante had significant wear problems.
