We have reviewed seven cases of fracture-separation of the distal humeral epiphysis, one of which was initially misdiagnosed as a fracture of the lateral condyle. There were difficulties in making the diagnosis. The injury must be distinguished from an elbow dislocation and a fracture of the lateral humeral condyle. All seven patients revealed posteromedial displacement of the distal humeral epiphysis on initial x-rays. Three patients were treated by closed reduction and cast immobilization, and four patients by open reduction and internal fixation. All three patients with conservative treatment had slight cubitus varus (under 5 degrees). Two patients with operative treatment had significant deformities of the elbow, one 25 degrees of valgus and one 20 degrees of varus. In treatment of these injuries, accurate evaluation of the state of reduction is most important. We got acceptable results with a conservative treatment.

Vnrus deformity is a common finding in patients who are candidates for toial knee replacement arthropiasty. To obtain excellent clinical results and to maintain well-aligned and stable prosthetic components in patients who have such a deformity, adequate ligament balancing as well as accurate cone.ction of bony alignment is required. But many technical problems are encountered. Especially the bony defect on the medial aspect of the tibia after adequate bone cutting and ligament imbalance with laxity in the lateral side and contracture in the medial side. Total knee replacement arthroplasty with 43 patients(56 cases) to be mcre than 10 degrees of varus of tibio-femoral angle was done by a single surgeon and reviewed retrospectively. The diagnosis was osteoarthritis in 46 cases, rheumatoid arthritis in 9 cases. The average follow up period was average 33 months(l-7 years). Preoperative varus deformity of average 13.5 degree., was corrected to valgus 6.69 degrees at last follow-up. Postoperative range of motion was 122.5 degree. And the mean knee society score improved from 24.8 to 87.2 postoperatively and the function score improved from 23.6 to 83.9 postoperatively. At self-assements, 88.2% of the patients was very satisfied or somewhat satisfied. Total knee replacement ;u1hroplasty in the patients with vaus deformity is effective procedure to corri.ct deformity and improve clini- c;1 and functional status, but long-term follow up period is required for changing alignment.

Manifest latent nystagmus (MLN) combined with esotropia may be confused with the nystagmus blockage syndrome (NBS), so the NBS may be overdiagnosed. The NBS is similar to MLN in the characteristics of the nystagmus and the clinical features, thus two diseases must be differentiated. In order to differentiate the MLN with esotropia from the NBS, accurate calibration of slow phase of nystagmus is essential with the aid of electro-oculography (EOG). With EOG recording, authors report a case of MLN associated with esotropia which may be misdiagnosed as the NBS.

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.

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.

Metacercariae of a kind of Levinseniella species were found from a brackish water crabs, Macrophthalmus japonicus de Haan, in the brackish area of Hyungsan river of Kyungpook province. Habitats were the epigastric and progastric regions of Macrophthalmus japonicus. One hundred and seventy five crabs out of 178 examined (98.3 per cent) were infested with metacercariae of Levinseniella species. The infested number of metacercariae in each crabs was average 100 ea. The excystation of metacercaria has not developed in vitro (both saline and tyrode's solution). Many eggs were observed in the metacercariae maintained for 24 or 48 hours in the water-bath. No differences were observed between semi-adult fluke from rat host and those maintained for 24 or 48 hours in vitro.
