Synovial sarcoma is comparatively uncommon and highly malignant tumor, which usually arises in proximity to a joint and may affect the adjacent bones. Occurence in finger and severe bony involvement are rare. We present a case of synovial sarcoma of the thumb, because the tumor arose in an unusual site and was characterized by severe bony destruction.

The purpose of this study was to access the effect of TMJ arthrocentesis in locking 8 patients with anterior distal displacement without reduction ( 'closed lock' ). TMJ Arthrocentesis was defined as needle puncture of the joint space and usually combined with lavage. After lavage, the mandible is gently manipulated to evaluate the movement. Arthrocentesis with irrigation has been used successfully with few complications and low morbidity. Postoperative therapy requires repetitive opening and excursive exercises to maintain and improve the function. The mean follow-up period was 17.1 months(range, 8 to 30months). Preoperative and postoperative mean maximal interincisal opening(MIO) was 25.4mm preoperatively and 39.8mm postoperatively. The pain was reduced in 7 out of 8(87.5%) patients with limited mouth opening. The result of this study indicate that TMJ arthrocentesis is an effective means of controlling pain and improving jaw movement in patients with closed lock.

The purpose of the present study lied in examining the incidence, treatment and failure causes of peri-implantitis by analyzing medical charts of those patients who underwent implant placement for the past 2 years. The subjects included those patients who underwent implant placement at the present hospital from January 2001 to December 2002. 3i implants were used for the analysis for the comparison of significance. A total of 301 patients were examined, among whom 102 were females and 199, males. Implants were placed in a total of 578 cases. The number of peri-implantitis was present in a total of 29 cases (21 males and 8 females), giving the incidence at 9.6%. The evidence of peri-implantitis was seen in 60 cases, which was in 10.4% of the patients. Among those cases with peri-implantitis, 28 cases (47%) underwent bone graft and 22 cases (43%) underwent maxillary sinus lift. Furthermore, 4 of these patients had systemic diseases such as diabetes or hypertension. Regular management is important for the preven ion of peri-implantitis. In other words, early prevention through regular follow-ups to check the status of surrounding soft tissue would be needed to maintain implants.

Owing to shared receptor components, the biological activities of IL-15 are similar to those of IL-2. However the patterns of tissue expression of IL-2/IL-2R alpha and IL-15/IL-15R differ. The development of agents targeting the receptor and signaling elements of IL-15 may provide a new perspective for treatment of diseases associated with expression of IL-15/IL-15R. We designed, genetically constructed and expressed a receptor site specific IL-15 antagonist by mutating glutamine residue within the C-terminus of IL-15 to aspartic acid and linked this mutant IL-15 to murine IgG2a. These IL-15 mutant/IgG fusion proteins specifically bound to the IL-15R, and competitively inhibited IL-15 triggered cell proliferation. We examined the immunosuppressive activity of this agent because of prolonged half-life and the potential for destruction of IL-15R+ leukocytes. The IL-15 mutant/IgG proteins markedly attenuated antigen specific DTH responses in Balb-c mice comparing with the responses in the mice treated with control IgG. Intraperitoneal injection of this mutant protein enhanced the acceptance of crude islet allograft from DBA/2J (H-2(d)) to B6AF1 (H-2(b/d),k) rendered diabetic by injection of streptozotocin (15 vs >65 days; control IgG vs IL-15 mutant/IgG treatment, mean survival time, 8 mice in each group). These findings suggest that i) IL-15/IL-15R+ cells are crucial to these T-cell dependent immune responses, and ii) treatment with IL-15 mutant/IgG protein may ameliorate T-cell dependent immune/inflammatory diseases.

A clinical analysis was done on 129 patients (131 cases) of the ankle fractures that were admitted and treated in Orthopedic Department, Inchon Christian Hospital from January 1973 to December 1980. The following results were obtained: l. Of the 129 patients, male was 104 patients and female 25 patients, the average age of the patients was 37. 2. The main cause of the injuries was traffic accident (38.2%), and the remain causes were industrial accident (28.2%), fall down (18.3%), slip down (11.5%), and sports injury (3.8%) in order. 3. The most common type by Lauge-Hansen classification was supination-external rotation type (37.4%). 4. In method of treatment, operative treatment was done in 72 cases and nonoperative in 59 cases. 5 The average duration of the cast immobilization in nonoperative treatment was 8 weeks and operative 7 weeks. 6. The better result was obtained by operative treatment than nonoperative one. 7. The most poor result was noticed in pronation-external rotation type according to Lauge-Hansen classification. 8. We agree that the accurate reduction of the lateral malleolus make the talus in good anatomic position in ankle joint. 9. We agree that Lauge-Hansen classification is useful in diagnosis and treatment of ankle fracture.
