The medial collateral ligament is the most commonly injured ligamentous structure of the knee. The management of the medial collateral ligament injuries were divided into surgical and conservative treatment. More recently, many investigators reported that isolated medial collateral ligament injuries did well under non-operative treatment. So, arthroscopic examination of the knee to rule out other intraarticular pathologic conditions such as cruciate ligament injuries, meniscal tear and osteochondral lesion is essential. From October 1993 to April 1995, we treated 45 cases of Grade III medial collateral ligament injuries and arthroscopic finding for cruciate ligament, meniscus, bony structure were analized in these cases. The result were as follows; 1. Anterior cruciate ligament injury:37.5% in +1 degree, 42.8% in +2 degree, 86.7% in +3 degree 2. Posterior cruciate ligament injury:12.5% in +1 degree, 13.4% in +2 degree, 33.3% in +3 degree 3. Meniscal injury:12.5% in +1 degree, 21.3% in +2 degree, 33.4% in +3 degree 4. Medial capsular ligament injury was more frequent and severe in the meniscofemoral ligament than in the meniscotibial ligament, but that finding was not correlated with degree of medial instability.

Fractures of the neck of the femur have always presented great challenges to orthopedic surgeons and still remain as one of the unsolved fracture as far as treatment and results are concerned. With life expectancy increasing with each decade, becoming more and more patients suffering from femoral neck fractures and their sequelae. The objoct of this study is to observe the relationship between the clinical results and the degree of displacement of fracture, degree of osteoporosis and duration between injury and operation in femoral neck fractures treated with multiple pin fixation. The author clinically analyzed 56 patients of the femoral neck fractures treated with closed reduction and multiple Knowles pinning followed by more than 1 year at Korea University Hospital from January 1986 to December 1991. There were 20 male and 36 female. The age of patients were ranged from 32 to 88 years(average:65.1 years) and most commonly occurred in 7th decade (23cases,41%). The most common cause was slip down(44 cases;79%). The most common type of fracture was stage III (48%) following to Gardens classification. The obtained results were as follows; 1. Union occurred in 49 cases(88%). 2. Among fifty-six cases, five cases(9%) of avascular necrosis, two cases(4%) Of non-union, two cases(4%) of malunion and one case of posttraumatic arthritis were occurred. 3. The functional results by Lunceford criteria were excellent in 30 cases(53% ), good in 13 cases(23%), fair in 5 cases(10%) and poor in 8 cases(14%). 4. Unsatisfactory results were noted in Garden stage II or IV, osteoporosis below Singh index 3 and delayed treatment over 1 week. Above results suggest that multiple Knowles pinning in femoral neck fractures offers high union rate and low complication rate, and so is also one of salvaging method of femoral head.

Analysis and prediction of the care charges related to colorectal cancer in Korea are important for the allocation of medical resources and the establishment of medical policies because the incidence and the hospital charges for colorectal cancer are rapidly increasing. But the previous studies based on statistical analysis to predictthe hospital charges for patients did not show satisfactory results. Recently, data mining emerges as a new technique to extract knowledge from the huge and diverse medical data. Thus, we built models using data mining techniques to predict hospital charge for the patients. A total of 1,022 admission records with 154 variables of 492 patients were used to build prediction models who had been treated from 1999 to 2002 in the Kyung Hee University Hospital. We built an artificial neural network (ANN) model and a classification and regression tree (CART) model, and compared their prediction accuracy. Linear correlation coefficients were high in both models and the mean absolute errors were similar. But ANN models showed a better linear correlation than CART model (0.813 vs. 0.713 for the hospital charge paid by insurance and 0.746 vs. 0.720 for the hospital charge paid by patients). We suggest that ANN model has a better performance to predict charges of colorectal cancer patients.

Pulmonary alveolar proteinosis is a rare disease of unknown etiology characterized by the accumulation of phospholipids and proteinaceous material in the alveolar spaces. Sequential bronchopulmonary lavage with 2-4 days interval has been the most acceptable method of treatment. Prognosis after bronchopulmonary lavage is very variable. We have experienced recurred case of pulmonary alveolar proteinosis. In this case we have performed sequential lavage in one stage safely. Complete removal of lavage fluid, facilitation of oxygenation by ventilation of lavaged lung with positive end expiratory pressure, and adequate evaluation of oxygenation enabled sequential lavage in one stage. We report a case of sequential bronchopulmonary lavage in one stage in a patient with a recurred pulmonary alveolar proteinosis.

PURPOSE: The purpose was to evaluate the procedure-related complications of the TIPS and its clinical significance. MATERIALS AND METHODS: The materials consisted of 52 patients who had 57 TIPS procedures for the management of variceal bleeding due to portal hypertension. To detect the occurrence of complications during transhepatic needle puncture(from hepatic vein to the portal vein), contrast material was injected with the withdrawl of the puncture needle. RESULTS: Procedure-related complications occurred in 28 patients (54%) among 52 patients. The corn lications were biliary tree puncture(15 cases), transperitoneal puncture(14 cases), stent malposition(3 cases) stent migration(1 case), hepatic arteries puncture(1 case), splenic vein perforation(1 case), and paroxysmal tricular tachycardia(1 case). Three patients had acute stent thrombosis with rebleeding immediately after procedure. The procedure was repeated in two patients. One patient was expired due to rebleeding. CONCLUSION: The procedure related complications were clinically insignificant in most instances, when stent thrombosis or proxysmal ventricular tachycardia was developed.

PURPOSE: This study was designed to verify intermediate-term functional and radiological results of limb salvage operation using endoprosthetic replacement system (MUTARS(R)) used in patients with a malignant bone tumor. MATERIALS AND METHODS: Thirty one cases which used MUTARS(R) tumor prosthesis were reviewed. The mean age of the patients was 49.2 years and the mean follow up was 39.8 months. We retrospectively reviewed complications, and evaluated functionally and radiologically by Enneking functional score, ISOLS radiological implants evaluation system at last follow-up. RESULTS: 3 patients had died of disease, distant metastasis was seen in 4 patients and local recurrence was seen in 1 patients. Complications were developed in 12 patients. (infection 6, leg length discrepancy 2, aseptic loosening 2, periprosthetic femoral fracture 1, screw loosening 1) Mean value of total functional scores were 81.2% in proximal femur, 77.4% in distal femur, 78.1% in proximal tibia, and 80.2% in proximal humerus. The overall radiological result was relatively satisfactory. CONCLUSION: Our results suggest limb salvage with the MUTARS(R) endoprosthesis is successful with good functional and radiological results. But we should be careful with complications such as infection.

Ectopic pregnancy refers to gestation in which the fertilized ovum implants on any other tissure than tbe mucus membrane lining the uterine cavity. Cornual (intertitial) pegnancy is a relatively uncommon but potentially catastrophic form of ectopic pregnancy, defined as implantation in the intramural portion of a fallopian tube. A hydatidiform mole usually occupies the uterine cavity but it's occurrence in the uterine tube is extremely rare. Only a few cases of primary hydatidifm mole of the tube have been reported. We experienced a case of ectopic hydatidiform mole in the uterine cornua and so present it with brief review of literatures.

PURPOSE: To evaluate protective mechanism of melatonin against radiation damage and its relationship with apoptosis in mouse jejunum. MATERIALS AND METHODS:' 168 mice were divided into 28 groups according to radiation dose and melatonin treatment. To analysis crypt survival, microcolony survival assay was done according to Withers an (l Elkind's method. To analysis apoptosis, TUNEL assay was done according to Labet-Moleur's method. RESULTS: Radiation protection effect of melatonin was demonstrated by crypt survival assay and its effect was stronger in high radiation dose area. Apoptosis index with 8 Gy irradiation was 18.4% in control group and 16.5% in melatonin treated group. After 18 Gy, apoptosis index was 17.2% in control group and 15.4% in melatonin treated group. Apoptosis index did not show statistically significant difference between melatonin treated group and control group. CONCLUSION: Melatonin shows clear protective effect in mouse jejunum against radiation damage but it.', protective effect seems not to be related with apoptosis protection effect.
