One case of congenital cutis aplasia is presented. The defect involved includes full-thickness skin defect of scalp and cranium. The patient was treated with debridement of dirty necrosed crust which covered exposed dura mater and with double opposing rotation flap including pericranium for bone regeneration. The donor site was covered with skin graft from right thigh. During operation, the superficial temporal artery was found to be short and weak. And after operation, the margin of flap were congested and finally necrotized. The necrotic wound was treated with conservative management. The vascular impairment is thought to be main course of congenital cutis aplasia. So we conclude that the treatment of choice is conservative management or careful flap surgery for coverage of defect area.

Effect of Mercury chloride on the synthesis of NO2- and ATP were observed in EMT-6 cells which were culture with cytokines(IL-1alpha and IFN-gamma) and various concentrations of mercury chloride from 0.05 to 0.08 M. Viability of EMT-6 cells were observed above 90% in almost groups. There were not significant differences in the viability between mercury supplemented groups and control group. It suggests viability of EMT-6 cells were not influenced by these concentrations of mercury chloride. Results of the synthesis of nitrite showed significant time and group effect. There is a significant interaction effect between concentration of mercury chloride and culture time. The effect of various concentration of mercury chloride is not the same for all levels of culture time. There were significant differences in the synthesis of nitrite between mercury chloride supplemented groups and control group, and the synthesis of nitrite in EMT-6 cell by the supplement of mercury chloride was significantly decreased in a dose-dependent manner. Results of the synthesis of ATP showed a significant group effect, and the time main effect and the Group x Time interaction were also significant. There were significant differences in the synthesis of ATP between mercury chloride supplemented groups and control group, and the synthesis of ATP in EMT-6 cell by the supplement of mercury chloride was significantly decreased in a dose-dependent manner. These results suggest that the disorder of cell mediated immunity by mercury chloride could be related to the inhibition of nitric oxide synthesis which will be caused by the decreased synthesis of ATP.

Calcaneus was the most commonly involved bone among the tarsal bone fracture. Many different methods have been tried for the treatment of fractures of the calcaneus in order to search for better results. But there is no general agreement on the treatment of the fracture of the calcaneus, especially involving the subtalar joint. From Jan. 1986 to Jan. 1990, 25 feet in 20 patients of calcaneal fractures involving the subtalar joint were treated by closed reduction & percutaneous pinning at the Dept. of Orthopedic Surgery, Chosun University Hospital and the results were as follows; 1. Of these intra-articular fractures, 15 fractures were tongue type and 10 fractures were joint depression type by Essex-Lopresti classification. 2. According to the Salama unit system, the results of treatment were excellent or good in 11 cases of 15 tongue types and 6 cases of 10 joint depression types. 3. The results were excellent in which reduction is achieved near anatomical reduction. 4. Even if the joint depression type fracture which is not severely comminuted, the treatment with closed reduction & percutaneous pinning is thought to be good method.

Since Klemm introduced the concept of antibiotic-containing bone cement for the treatment of chronic osteomyelitis, a number of studies have demonstrated the positive results of this therapy. It has been proved that antibiotic-containing bone cement continuously releases high levels of atibiotics locally into the infected and avascular wound environment. Antibiotic-containing bone cement provides several distinct advantages over irrigation-suction drainage. The major objective of this study is to analyze the results of therapy using antibiotic-containing bone cement beads for chronic osteomyelitis. The authors analyzed 21 cases of chronic osteomyelitis in patients who had been treated by saucerization and antibiotic-containing bone cement beads at Chosun University Hospital, between February 1990 and January 1993. Each patient's case was followed for at least thirteen months after operation. The results are as follows: 1. The causes of osteomyelitis were postoperative complications(10 patients), open fracture(8 patients), and hematogenous osteomyelitis(3 patients). 2. Staphylococcus aureus was the most common organism causing osteomyelitis, followed by Pseudomonas. 3. The femur was the most common location of lesion(11 patients) followed by the tibia(7 patients), the humerus(2 patients) and the ulna (1 patients). 4. Pus drainage was stopped in 13 cases with one insertion of the beads, in 2 cases with two insertions and in 2 cases with three insertions. 5. Therapy using antibiotic-containing bone cement beads can be regraded as an effective method of increasing local antibacterial activity by releasing the antibiotic into surrounding tissue over a continuous period in the treatment of chronic osteomyelitis. Antibiotic-containing bone cement beads are useful in the treatment of chronic osteomyelitis.
