Electrical burns constitute a unique type of thermal injury. With the passage of high tension current through body surface, 2,500 to 3,000℃ heat was generated, and lead to coagulation of blood vessels, nerves, muscles, skin and other structures. Therefore, electrical burn differs from thermal burn in the point of extent, degree, fluid and electrolytes therapy. From February, 1979 to April, 1982, clinical study was performed in 17 patients with electrical burn of more than 20%, and formula used in thermal burn was modified, further then this modified formula was applied to the fluid and electrolytes therapy. The brief summary of observations were as follows: 1. Fluid loss below the necrotic limb was negligible, and only cut surface between the necrotic limb and viable limb was regarded as actual fluid loss area. 2. In many cases, amputation of extremities in electrical burn was inevitable due to irreversible changes in deep structures. 3. Amputation stump was not well fitted in most cases due to multiple skin damage and deep tissue injury in different levels of extremities.

The effect of intravesical formalin instillation as a therapeutic modality for intractable bladder hemorrhage in well known. And despite clear evidence of therapeutic efficacy of intravesical cytotoxic drugs and / or BCG immunotherapy, there have been substantial recurrences during follow up after transurethral resection for superficial bladder tumor. If formalin injected at the bed of superficial bladder tumor is able to coagulate and necrotize the tumor, it will be greatly helpful to the patients with recurrent bladder tumor developed during follow up. Since this technique is applicable on outpatient basis, an economical as well as a psychological burden of the patients can be reduced considerably. The purpose of this study is to evaluate the effect of submucosal formalin injection on rat bladder wall. 36 healthy adult male Sprague-Dawley rats (weighing 350 gm in average) were divided into 3 groups: In Group I (control group), 0.01ml of normal saline was injected submucosally at the left posterolateral wall of the bladder opened under intraperitoneal Nembutal anesthesia; In Group II and III, 0.01 ml of 10% and 4% formalin, respectively, were administered at the same site as in the Group I, two rats in each group were sacrificed at day 1, 2, and 3, and week 1, 2, and 4 after injection, respectively. Gross and microscopic examination of the cystectomized specimen were done in each group. In the Group II, bladder stones were formed at week 1, and in both the Group I and III, stones were seen at week 2 post injection. There was no significant difference in histologic findings of the bladder between the group II and III. Mucosal ulcer and/or prominent mucosal disruption was observed at 24 hours after injection in both Group II and III. Epithelial regeneration began at day 2, and was marked at day 3, and epithelial lining was almost normalized one week after injection. Subepithelial edema, telangiectasia and inflammatory reaction were prominent at 24 hours post formalin injection. Subepithelial edema persisted in moderate degree for 1 week. Telangiectasia and inflammatory reaction were noted for 4 weeks. Mild degree of these findings also appeared in the control group. Fibroblastic proliferation appeared at day 2 and persisted in moderate degree for 4 weeks. There has been no mortality or bladder perforation. These results suggest that clinical application of this technique is feasible for the selected cases of recurrent, solitary superficial bladder tumor. However, optimal dosage of formalin in relation to the size of the lesion remains to be investigated.

PURPOSE:Effects of IDDM on bone mineral metabolism are still in controversy. Some reported that bone mineral density in IDDM had inverse relationship with HbA1c, some reported that spine BMD was normal while femur BMD was decreased. Others reported that increased urinary calcium excretion in IDDM induced early trabecular bone mineral loss. We studied the correlation of BMD with diabetic control and body measurements. METHODS:In sixteen IDDM patients, using dual energy X-ray absorptiometry, BMD was measured in lumbar spine as trabecular bone and femur neck as cortical bone. Z-score of BMD was obtained by comparing age and sex matched control data. Correlations between BMD and diabetic control parameters (HbA1c, duration of IDDM) and body measurements were calculated. RESULTS:The body measurements were in normal range in all IDDM patients, the duration of IDDM was 38.4+/-24.0months, HbA1c was in good control state (7.69+/-1.53%), and urinary Ca/creatinine ratio was not increased. The Z-score of BMD was not decreased statistically (lumbar spine: -0.255, femur neck: -0.404), and the Z-score had no correlationship with body measurements and diabetic control parameters. CONCLUSIONS:In well controlled childhood IDDM, BMD was not decreased significantly.

The anterior cruciate ligament(ACL) is one of the main structures which have a stabilizing function of the knee. If a knee with a complete tear of ACL is not treated operatively, progressive instability develops, and the knee has a high risk of incurring meniscal is required. From March, 1989 to December 1992, we reconstructed ACL using patellar tendon with Kennedy-ligament augmentation device(LAD) in 26 patients. Nine patients had acute injuries and 17 patients had chronic rupture. In eleven patients operation was done arthroscopically, and in fifteen patients operation was done by arthrotomy. We used quadriceps tendon-patellar periosteum-patellar tendon in 16 cases and bone-patellar tendon-bone in ten cases. The length of follow-up ranged from 6 month to 33 months (mean; 10 months). We obtained satisfactory results in 22 cases.

In 1941, Jaffe and coworkers studied a lesion with histologic appearance of fibrous stroma, pigmented deposition and histiocytic infiltration as well as giant cell, for which they named pigmented villonodullar synovitis, bursitis and tenosynovitis. Thereafter many authors have disscussed etiology, clinical and radiological features, pathology and treatment regarding the disease. Recently we experienced a case of pigmented villonodular synovitis involving an hip joint which was treated by synovectomy and total hip replacement with good result.

Vertical and marginal fractures of the patella are uncommon injuries compared with other types of patellar fracture. It's possible that they are more common than supposed, but often remain undiagnosed as acute injuries. Vertical and marginal fractures often results in less acute disability than stellate or transverse fracture and the routine radiographs are often unhelpful. Failure to diagnose acute vertical and marginal fractures of the patella, especially when the fragments are displaced, may result in prolonged disability of the knee and possible development of degenarative changes in the patello-femoral joint later. Twelve patients of the vertical and the marginal patellar fractures treated at St. Mary's Hospital from Feb. 1982 to Dec. 1987 were analyzed in clinical and radiological aspect. The results obtained from this study were as followings. 1. Vertical and marginal fractures had 15.4% of injury rate in all patellar fractures. 2. The fracture and its displacement were always present on the tangential view of the patella. 3. The mechanism of the fracture was s direct blow to the patella in which the affected knee was flexed. 4. The location of the fracture line was related to the degree of the flexed knee at the time of fracture. 5. Large separated fragments of the patella should be accurately reduced with rigid fixation in the rationale of the intraarticular fracture.
