1.Total Wrist Arthroplasty (Three Cases Report)
The Journal of the Korean Orthopaedic Association 1989;24(4):1173-1178
We have performed three total wrist arthroplasty of Meuli type on the dominant wrist of three female patients who have been suffering from the classical rheumatoid arthritis for more than two years, and after follow them for average twenty months postoperatively, we have found, even the complications and reoperation rate after total wrist arthroplasty are reported high in literature, three patients have reasonably satisfied with the remarkable relief of pain and the functional abilities of their wrists. It is our belief, even if the total wrist arthroplasty is also still in controversy, that in those patients with bilateral wrist involvement by the rheumatoid arthritis in whom arthrodesis was done on one wrist, then a total wrist arthroplasty on dominant wrist is a most prefer way to reconstruct the disabled wrists.

Aneurysmal benign fibrous histiocytoma(ABFH) is a relatively rare variant and has a distinctive histopathological features, that is collections of capillaries, foci of hemorrhage, siderophages, and foamy macrophages surrounding cleft-like and cavernous blood filled spaces in the tumor. But, in spite af the distinctive features, it is not infrequently confused with malignant melanoma, angiomatoid malignant fibrous histiocytoma, and vascular tumors such as spindle cell hemangioendothelioma, nodular Kaposi's sarcoma and angiosarcoma. We report a case of ABFH developed on the left upper extremity of a 41-year-old man.

Tinea faeiei is an unusual fungal infection which often is not recognized by clinieians. Because of light sensitivity, the frequent absence of typical clinical manifestation, and secondary changes due to steroid treatment, this condition is frequently misdiagnosed with other dermatoses. We described two patients who showed atypical facial lesions which were histologically diagnosed as tinea faciei. The case I was a 54 year old male who had multiple discoid plaques and nodules on the face. The other case was a 83 year old female who showed scaly plaques, nodules, pustules, and photosensitivity on the face. Histologic exarnination revealed fungus spores and mycelia within the inflamed hair follicles.

It is well-known that the infection of bone and joints could produce the shortening by destroying the articuiar cartilage and growth plate, or the lengthening hy increased hlood circulation to the epiphyseal and metaphyseal regions of long bone. Since 1985, we have treated total l7 cases of children s pyogenic or tuberculous children s knee with early arthrotomy and continuous irrigation etc. and followed their long hone growth for average 53 months after surgical intervention. Five patients (group I ) were early treated within 2 weeks and twelve patients(group 3 ) were delayed to treat their knees for more than 2 weeks of symptom development. Total 11 patients out of 17 cases(64.7%) (2 cases of group 1 pyogenic arthritis, and 1 case of group l and 8 cases of group II tuberculous arthritis) revealed growth acceleration. Femoral lengthening was much more greater than that of tibial growth, and the size of patella, distal femoral and proximal tibial epiphysis which were measured by computerized digitizer were also significantly larger than that of opposite knee. The total limb length was increased hy average 7mm in 6 months, l4mm in 1 year and 3mm in 2 years after operation. These results suggest the pyogenic and tuberculous arthritis in children s knee should he treated as early as possible after symptoms developed, and followed them to trace their limh inequality for at least 2 years after surgery. That means the early arthrotomy for tuberculous knee or even in pyogenic arthritis can preserve normal articular cartilage and can also prevent the early epiphyseal closure hy infection. and can get the limh lengthening by increased blood circulation around the knee joint.

PURPOSE: To analyze clinical, radiological and pathological features as well as clinical outcome after surgical treatment of patients with secondary chondrosarcoma arising from osteochondroma(tosis). MATERIALS AND METHODS: We retrospectively reviewed clinical records, radiographs, pathologic slides of 14 patients. Nine patients were male and five were female. The mean age was 34 years. The mean follow-up period was 54 months. RESULTS: All patients had a history of previous mass since childhood or puberty. Preexisted osteochondroma was single in 3 patients and multiple in 10. Remaining 1 patient had multiple osteochondromatosis with enchondromatosis. MRI clearly provided thickness of cartilage cap, which was over 2 cm except in 2 cases. Chondrosarcoma was grade 1 in all except 1 case, which was grade 2. Wide excision was performed in 10 patients, marginal excision in 3 and amputation in 1. Twelve patients were doing very well without evidence of disease. Among 3 patients with marginal excision, 1 patient had local recurrence and 1 patient died of disease. CONCLUSION: Comprehensive understanding of clinical, radiological and pathological features of secondary chondrosarcoma is warranted for accurate diagnosis. The best result can be expected with early recognition of malignant change of osteohcondroma(tosis) and wide excision.

PURPOSE: To investigate prognostic factors influencing on local recurrence, distant metastasis and event-free survival of liposarcomas. MATERIALS AND METHODS: Fifty-two patients managed for liposarcomas since 1993 were analyzed respectively in the view of prognostic influence of patient age, tumor size, location, histologic type, histologic grade, resection type, surgical margin, chemotherapy and radiation therapy on local recurrence, distant metastasis and event-free survival. The mean follow up period was 39 months. The univariate and multivariate regression analysis were performed for statistical evaluation. RESULTS: The local recurrences occurred in 11 patients (21.2%) and distant metastasis in 4 patients (8%), Event-free survival rate at 4 year follow up was 67%. In univariate analysis, histologic grade, surgical margin, chemotherapy and radiation therapy were significant prognostic factors on local recurrence (p<0.05). However, histologic grade lost its significance in muitivariate analysis. Trunk location revealed higher rate of distant metastasis than extremity location. In univariate analysis on event-free survival. histologic grade and chemotherapy were significant factors (p<0.05). No factor remained significant in multivariate analysis. CONCLUSION: Considering selection bias, positive surgical margin was negative prognostic factor on local recurrence. Liposarcomas arisen in trunk revealed higher rate of distant metastasis. There was no independent prognostic factor on event-free survival of patients with liposarcomas.

PURPOSE: We evaluated oncologic outcomes of chondrosarcomas and analyzed the disease-free survival rate of chondrosarcomas according to the various factors. MATERIALS AND METHODS: We performed a retrospective study for the disease-free survival rate of 48 chondrosarcomas, 44 of which underwent surgical treatment and followed up more than 18 months since 1993, and in the remaining 4 cases, the patients died before 18 months after surgery. The vsariables were location, tumor volume, histologic grade, stage, age at presentation and treatment performed. The mean follow up period was 43.8 months (1-196 months). RESULTS: The overall disease-free survival rate was 77.1% at mean 43.8 month follow up. The 5 year- and 10 year disease-free survival rates were 64% and 58% respectively. The histologic grade, stage, age at presentation revealed statistical significance on disease-free survival. All 9 patients treated with extended curettage for grade 1 central chondrosarcomas revealed disease-free survival with excellent functional outcome. CONCLUSION: The disease-free survival rate of chondrosarcomas mainly depended on histologic grade, stage and age at presentation. Local recurrence and distant metastasis also revealed statistically significant differences of disease-free survival rate. Comparing to wide resection, extended curettage for low-grade central chondrosarcomas in extremities were efficient methods with similar survival rate and less functional losses and complications.

BACKGROUND: A stenosis of left main coronary artery has critical prognostic importance. Recent reports on successful left main stenting are now challenging traditional treatment patterns for this lesion. We evaluated recent four-year trends in incidence, clinical, angiographic findings and treatment modalities in patients with left main coronary artery stenosis(LMS). METHODS: Patients who were diagnosed as a significant LMS at Yonsei cardiovascular hospital between 1996 and 1999 were analyzed retrospectively. RESULTS: The incidence of LMS during the period of 1996 to 1999 was 3.3%(n=24) and it was significantly higher than that of previous 15 years before 1996(p<0.01). The incidence of isolated ostial lesion was 0.28% and this lesion was more prevalent in young female patients with less risk factors compared with other types of LMS(p<0.01). After exclusion of the patients with an isolated ostial lesion, patients were grouped according to the lesion site: ostium, shaft, and shaft lesion extended to distal vessels. There were no differences in clinical and hemodynamic findings among these groups. Coronary artery bypass graft was performed in 141 patients(63%) and stent implantation in 16 patients(14%). CONCLUSION: The incidence of LMS has been increased. There was no difference in clinical and hemodynamic findings according to the types of LMS. Surgery is still a standard treatment, but in selected patients percutaneous coronary intervention can be another treatment option.

A 53-year-old man developed some erythematous follicular macules accompanied with tingling sensation on both shoulders. Histologic finding showed a dense lymphocytic infiltrate around the infundibular portion of the follicle, where separation of the dermoepidermal junction was seen. The insect, obtained from the skin lesion, was identified as a larva of an Ap- hid
