Distal foot defect is frequently encountered as an output site in high-tension electrical burn injuries, and proper treatment methods should be applied in order to achieve a properly-functioning foot. However, in distal foot defects around the metatarsal heads or metatarsophalangeal joints, conventional methods have not been ideal, replaced by such methods as secondary healing, amputation or skin graft because there was insufficient tissue in the distal foot and the general condition of the patient was unsuitable for distant or free flap surgeries. So, in order to establish convenient, promising methods for the reconstruction of distal foot defects in severe electrical burns, we classified the distal foot into four zones according to their blood supply and we defined or created ideal reverse flaps in each zone. From April 1996 to March 1999, we reconstructed 43 cases of distal foot defects in fourth-degree high voltage electrical burn wounds. In 19 cases of MP(medial plantar) zone injuries, we used reverse medial plantar island flap and in 5 cases of DP(dorsalis pedis) zone, we created a reverse dorsalis pedis island fascia flap, In 11 cases of P(peroneal) zone, we created reverse peroneal fascia flap and in 8 cases of I (intermediate) zone, we modified a reverse posterior tibial island flap, There was partial flap necrosis or grafted skin loss in five cases, but those were extremely minor problems and we successfully reconstructed distal foot defects in all 43 cases. In conclusion, proper reverse flaps according to the zone of the distal foot are ideal reconstructive methods because they provide good vascularization, sufficient tissue from the proximal parts and they require short operative time with relatively easy procedures.

The purpose of this study was to investigate what the intermediate filaments in the cells of rat mandibular fossa fibrous layer are and any relationships between the presence of these filaments and aging. Mandibular fossae of 4 groups of rats(14-day, 28-day, 55-day and adult groups) were removed on bloc and processed for immunostaining and were subjected to light microscopic examination. The results were as follows : In 14-day group, there were no immunoreactive cells in fibrous layer of mandibular condyle articular surface. But in 28-day group, many immunoreactive cells were seen in fibrous layer, especially central portion of articular surface of mandibular fossa. These cells were fusiform shaped and immunoreactivities were seen in the cytoplasm around the nucleus. In 55-day group many immunoreactive cells were seen in fibrous layer of mandibular fossa. These cells were fusiform shaped and distributed evenly in central portion of this fibrous layer. Immunoreactivities were seen in the cytoplasm around the nucleus. In adult group, the results were similar to 55-day group, Many immunoreactive cells were seen in fibrous layer of mandibular fossa especially central portion. According to these results, vimentin immunoreactive filaments appear with aging and increment of mechanical load associated with incision or mastication.

A 55 year old male complain right shoulder pain and right upper quadrant pain about three months. He was a heavy alcoholism. Highly selective angiography, CT scan and operation findings suggest primary malignant neoplasm of the liver. Right hepatic lobectomy and partial diaphragmectomy was done under impression of heaptocellular carcinoma. The specimen measured 15x11x9 cm and disclose relatively hard and nodular mass devoid of cirrhotic changes. Cut surface show unilobar large mass measuring 11x8x6 cm and bearing brightly yellow discoloration and multifocal hemorrhagic necrosis. Histological characteristics were diffuse proliferation of large neoplastic cells with ample cytoplasm, containing granular materials, erythrophagocytosis, neutrophagocytosis and hemosiderin pigments. Atypical and bizarre mitosis and multinucleated giant cells bearing abundant erythro and neutrophagocytosis were frequently seen. The large or vesicular nuclei were irregular, with occasional deep indentations and revealed sharply defined nuclear membrane, coarse chromatin and conspicious nucleoli. Ultrastructurally the cytoplasm of neoplasltic cells had lysosomal granule, phagolysosome, phagocytized material and residual bodies. Immunohistochemical stains for alpha 1-antitrypsin, alpha 1-antichymotrypsin, vimentin and lysozyme showed positive reactions, but, alpha fetoprotein, cytokeratin, S-100 protein, factor VIII, complement 3 receptor and carcinoembryonic antigen were negative. Alpha-naphtyl acetate esterase activity in paraffin embedded tissue ribbon showed negative reaction. These findings show compatible with primary malignant lymphoma, true histiocytic type, (histiocytic sarcoma, Kupffer cell carcinoma) of the liver.

To know the pattern of visual field (VF) defect of low tension glaucoma (LTG), its diffuse and localized VF defects were compared using the significance values (p-value) of mean deviation (MD) and corrected pattern standard deviation (CPSD), which are calculated with STATPAC in Humphrey Visual Field Analyser. Sixteen eyes of LTG were enrolled and 34 eyes of primary open angle glaucoma (POAG) were used as controls. The degree of VF defects in LTG and POAG was relatively mild with the p-value of MD equal to or greater than 1%. Neither mean MD nor mean CPSD of LTG was significantly different from each of POAG (p > 0.8 and p > 0.2, respectively). Comparing the p-values of MD and CPSD, many patients showed more significant p-value of MD in LTG and POAG (62.5% and 61.8%, respectively). However, relatively more severe defect of CPSD tended to occur more frequently in LTG than in POAG (25% and 5.9%, respectively, chi-square = 4.964, p < 0.09). The relation between p-values of MD and CPSD was not significantly influenced by the intraocular pressure, MD or vertical cup to disc ratio in either LTG or POAG.
