Purpose: We wanted to evaluate the clinical and radiologic results of acetabular revision using the acetabular reinforcement ring and also the allograft impaction in the acetabulum having deficient bone stock. Material and Methods: Nineteen hips revision arthroplasty were performed in 18 patients (9 males and 9 females) with using an acetabular reinforcement ring and allograft between July 1993 and December 2003. The patients were followed for an average of 64 months (range: 24-153). The mean age at the time of arthroplasty was 59 years old (range: 34-76). The causes of revision were aseptic loosening of the acetabular component in 16 cases, severe progressive osteolysis around the acetabular component in 2 cases and Girdlestone state after infected total hip arthroplasty in one case. The acetabular deficiency was type II in 5 hips, type III in 13 hips, and type IV in one hip according to the AAOS classification. The clinical results were evaluated using the modified Harris hip score, and the radiologic results were evaluated by assessing the preoperative and serial follow-up radiographs. Results: The mean preoperative Harris hip score of 47 was improved to 86 points at the latest follow-up. Periacetabular osteolysis was found in 2 cases, which did not progress at follow-up. The anatomic hip center was restored after revision arthroplasty (p<0.05). Complications were dislocation in 2 cases, breakage of the hook of the Ganz ring in one case, heterotopic ossification in one case and femoral artery injury in one case. All cases showed stable fixation of the acetabular component and good remodelling of the impacted allograft. There was neither recurrence of dislocation nor progression of the acetabular component loosening on the radiographs. Conclusion: Acetabular revision with acetabular reinforcement ring and allograft impaction showed satisfactory clinical and radiologic results with restoration of the hip center and consolidation of the allograft.

In order to investigate causative mechanisms of optic neuropathy, retrospective clinical studies including ophthalmologic examination, imaging study, and molecular biologic analyses were performed on 322 patients with optic neuropathy. The causes include hereditary optic neuropathy(71 patients, 22.1%), optic neuritis(66 patients, 20.5%), traumatic optic neuropathy(40 patients, 12.5%), ischemic optic neuropathy(35 patients, 10.9%), compressive optic neuropathy(31 patients, 9.6%), toxic optic neuropathy(23 patients, 7.1%), etc. In 29 patients of bilateral optic atrophy and 18 patients of unilateral optic atrophy, the causative mechanism was not clear. In conclusion, hereditary optic neuropathy was the most common causative mechanism of optic neuropathy in this study. The importance of meticulous history taking and molecular biologic test should be stressed in differential diagnosis of optic neuropathy.

PURPOSE: Recently developed BMS(TM) (Zassi Bowel Management System(TM): Hollister Inc., Illinois, USA) can provide effective nonsurgical fecal diversion without the risks associated with colostomy creation and subsequent closure. Our aim is to evaluate the effectiveness of the BMS in diverting feces from the perianal wide surgical wound in patients with Fournier's gangrene. METHODS: BMS(TM) was applied in five patients (male: 2, median age; 44) with Fournier's gangrene from January 2000 to September 2001. The treatments consist of three times a day wound dressing after wide surgical debridement and intravenous antibiotic therapy. For evacuation of feces, twice daily warm saline irrigation was administered via BMS(TM) or low daily doses of polyethylene glycol solutions were orally taken in. An endoscopic and anorectal manometric study was done to evaluate possible mucosal complications and anorectal functional changes. RESULTS: The average duration of the BMS application was 41 (range, 22~63) days. The result of a manometric study after immediate removal of the BMS(TM) showed a decreased mean resting pressure (range: 22~36 mmHg) and a decreased mean squeezing pressure (range: 32~39 mmHg). After 3 days, the sphincter pressure had improved markedly: mean resting pressures of 38, 45, 60, and 63 mmHg and mean squeezing pressure of 78, 89, 91, and 101 mmHg respectively. Fecal incontience was not noted in any patient. Other possible mucosal complications were not noted. There were no mortalit. CONCLUSIONS: BMS(TM) application in Fournier's gangrene patients after surgery successfully avoids a defunctioning colostomy. Furthermore, no significant complications were noted over a prolonged period up to 63 days.

The purine antimetabolite 6-Mercaptopurine (6-MP) has been in clinical use for over 30 years and is still a widely used agent in the treatment of childhood acute lymphoblastic leukemia. The bioavailibility, clinical efficacy and toxicity of 6-MP administered orally for maintenance therapy of children with acute lymphoblastic leukemia are highly variable in many studies, as well as at differnt times in same patient. there are many factors affecting the bioavailibility of 6-MP. The most notably factor being that concomitantly administered drugs and foods might contribute to a decrease in the bioavailibity of this drug. In our sociocultural environment milk is a major constituent of child's foods. Cow's milk contains a high concentration of xanthine oxidase, which could potentially transform 6-TM into 6-thioxanthine (6-TX) and 6-thiouric acid (6-TUA) which have no more therapeutic effects. In this study, we evaluated the effect of various milk products on the bioavailability of 6-MP. Incubation at 37degrees C for 30 min raw or pasteurized milk resulted in transformation of a large quantity of clinically relevant concentration of 6-MP into 6-TUA. The concomitant adminstration of folic acid and allopurinol has markedly inhibitory effect on the 6-MP destroying activity of milk at clinically relevant concentrations. These observations may help to optimize modalities of administration of 6-MP for the treartment of patients with childhood leukemia.

The shoulder fusion is one of the good method to relieve pain, improve the function and stabilize the flail shoulder joint. But recent advance of arthroplasty, the procedure is less popular. Authors studied and analized 23 patients who received shoulder arthrodesis from Aug. 1978 to Aug. 1986 and reported functional outcome after shoulder arthrodesis. Among twenty three patients, brachial plexus palsy were eighteen, upper extremity residual poliomyelitis in three and shoulder joint turberculosis in two respectively. Postoperative follow up was 12 months to 9 years and 6 months, average being 2 years and 6 months. It took 14.4 weeks in average for shoulder arthrodesis. The postoperative abduction fusion angle was 33.8 degrees in average(20 degrees to 50 degrees). The active abduction after shoulder fusion was mean 51.8 degrees(20 degrees to 85 degrees). The abduction fusion angle between 20 degrees and 40 degrees was presented satisfactory results in the point of pain relief, functional assessment and patients satisfaction. High abduction fusion angle(more than 40 degrees) revealed pain around the fused shoulder area. The combined extra and intraarticular arthrodesis revealed better results. The Saber-cut approach was more valuable for secondary elbow reconstruction than Henry approach.
