A 15-year-old female patient had malignant atrophic papulosis(Degos' disease) that affected the skin and probably intestinal tract. She had multiple erythematous papules with porcelain-white atrophic centers on the trunk and extremities. Also she suffered from intermittent nausea, vomiting and abdominal pain. She received appendectomy for abdominal pain 2 months ago. Histopathologic studies showed atrophic epidermis and necrobiotic dermis. There were endothelial thickening, fibrinoid necrosis of bload vessels, perivascular lymphocytic infiltation in the lower dermis. She was treatd with acetyl salicylic acid and dipyridamole, but there was no improvement.

Infantile hemangiopericytoma deserves separate consideration from adult form of hemangiopericytoma in that it has a benign clinical behavior and distinct histology. We herein report a case of infantile hemangiopericytoma in a 80-day-old male. He had multiple tender subcutaneous nodules on buttock and lower extremities which disappeared spontaneously in 10 months. Microscopically, well circumscribed multiple tumor nodules were seen in the dermis and subcutis and the nodules were consisted of haphazardly packed cells around endothelium-lined vascular slits. Infantile hemangiopericytoma is usually soliitary and spontaneously healed case has not been reported yet.

O1igodendrocytes are known to be responsible for the synthesis and maintenance of myelin sheath in the central nervous system, and their functional disturbance leads to defect in myelination. But, the fine mechanism of myelination by oligodendrocytes is not yet known, and iron metabolism in central nervous system is suspected to be related with myelination process by oligodendrocytes. Carbonic anhydrase-II[CA-II], transfe-rrin, and ferritin are known to be present at oligodendrocytes and suspected to play a role in iron metabolism of central nervous system. In this study, demyelination and remyelination of ICR mouse brains were induced using cuprizone, the copper-chelating agent, and immunohistochemical changes of CA-II-, transferrin-, and ferritin-immunoreactive oligodendrocytes at corpus callosum were observed. During demyelination by cuprizone feeding, the numbers of CA-II- and transferrin-immunoreactive oligodendrocytes were decreased. Especially, the decrease ratio of CA-II-positive cells was great. In contrast, the number of ferritin-positive oligodendrocytes was increased during demyelination by cuprizone feeding. Cessation of cuprizone feeding leaded remyelination and the numbers of CA-II-, transferrin-, and ferritin-immunoreactive oligodendrocytes were returned to normal level. In conclusion, the derangement of iron metabolism in oligodendrocytes may be related to demyelination mechanism of central nervous system, and the CA-II is suspected to have an important role in iron metabolism of oligodenrocytes in relation to demyelination and remyelination induced with cuprizone.

PURPOSE: To compare the radiological and clinical results between intramedullary nailing and plate fixation in the treatment of distal tibial fractures. MATERIALS AND METHODS: 19 cases of distal tibial metaphyseal fractures within 4 cm of the ankle joint line were enrolled. Ten patients were treated with interlocking intramedullary nail and the others with plate and screws. RESULTS: The mean union time was 14 weeks in nailing group and 16 weeks in plate group. The average angulation in AP view was 4.1 degrees in nailing group and 3.1 degrees in plate group. The average angulation in lateral view was 1.7 degrees in nailing group and 2.7 degrees in plate group. The rotational deformity was 2.8 degrees in nailing group and 1.7 degrees in plate group in average. There was no implant failure and soft tissue problem. CONCLUSION: There was no difference in clinical and radiological results between intramedullary nailing and plate in the treatment of the distal tibial fractures and, considering the preservation of the soft tissue, the intramedullary nails are a reliable method for managing distal metaphyseal fractures of the tibia.
