As the use computed tomographic (CT) scanning spread, the diagnosis of blowout fractures of the medial orbital wall increased. Now, the diagnosis of blowout fracture in the medial wall are not uncommon. Conventionally, the surgery of blowout fractures in medial orbital wall was performed by the various approach with external incision. The conventional method had seveal possible disadvantages, including an external scar, incomplete reduction, increased mobidity rate and general anesthesia. Recently, endoscopic reconstruction of the medial orbital wall has provided good functional and cosmetic results. We performed endoscopic transnasal reduction surgery without external incision in 12 cases of medial blowout fracture under local anesthesia. The fractured bony fragments were removed after the intranasal ethmoidectomy and the entrapped medial rectus was released. And then a sheet of silicone late or uncinate process were placed on the fracture site. For the maintain of the position of fractured wall, Merocel packing or urinary ballon catheter were used in orbital fracture site for 1-3 weeks. There were no specific complications related to this procedure. Result of the surgery in all cases were satisfactory. In this article, we discussed the surgical procedure, the benifit of the transnasal endoscopic approach, the indications for surgery, and possible comlications.

This experimental study was conducted to evaluate the effect of indomethacin and methylprednisolone on PAN-induced nephrosis in rats. Sprague-Dawley rats weighing 150~200gm were used and divided into controls, group I (PAN intraperitoneally), group II(PAN intraperitoneally, followed by indomethacin peritoneally for 12 days), group III (PAN intraperitoneally, followed by methylprednisolone peritoneally for 12 days) and group IV (PAN intraperitoneally, followed by cyclosporin subcutaneously for 12 days). Twenty four-hour urinary protein excretion was measured on day 0, 5, 10 and 17. On the 17th day, rats were sacrificed for the determination of total serum protein, albumin and cholesterol levels. Foot process widths of glomerular epithelial cells were measured, and anionic sites of lamina rara externa were determined by using PEI as cationic probes. The following results were obtained. Twenty four-hour urinary protein excretion (mg/day) of group I was significantly increased to 455.7+/-188.8 on the 5th day compared to 15.2+/-3.7 on day 0 (p<0.01), and increased gradulally to 525.6+/-203.5 on the 10th day, then decreased to 280.6+/-25.2 on the 17th day. In group III, 24 hr urinary protein excretion on 17 th day (180.7+/-64.5) was significantly lower than that of group I (280.6+/-25.2). Total serum protein of group III was significantly lower than that of group I, and serum albumin and cholesterol did not show any significant difference among Group I, II, III and IV. Foot process widths (nm) of glomerular epithelial cells in group I, II, III and IV were 409.5+/-15.2, 387.8+/-49.2, 279.9+/-36.9 and 398.3+/-38.3, respectively. And the value of group of group III was significantly lower than that of group I (p<0.01). The number of anionic sites per 1micrometer length of glomerular basement membrane in Group I, II, III and IV were 10.3+/-1.3, 10.1+/-1.6, 12.5+/-1.5and 10.2+/-1.5, respectively. And the value of group III was significantly lower than that of group I (P<0.01). In conclusion, cyclosporin and indomethacin did not show any significant effect on PAN nephrosis in rat. However, methylprednisolone reduced the urinary protein excretion and showed significant recovery of foot process widths and number of anionic sites of glomerular basement membrane.

Cortical dysplasia is a cause of intractable epilepsy and a candidate for surgical resection to control epileptic attacks. The neuronal cytomegaly and balloon cell change are the diagnostic hallmarks of cortical dysplasia. Little research has been performed about the normal-sized dysplastic neuron which has complex arborizing dendrites and lacks in its polarity. The aim of this study was to define the histopathologic characteristics of the neurons in cortical dysplasia. Twelve cases of cortical dysplasia who underwent partial lobectomy for intractable seizures were selected and immunohistochemical staining for NF-M/H, MAP2, tau, and ubiquitin was performed. The perikarya and dendrite of dysplastic neurons were more intensely labeled with antibodies for the high and medium molecular weight neurofilament proteins (NF-M/H) than normal neurons. Immunoreactivity with the MAP2 antibody expressed mainly within the somatodendritic regions was present in the dysplastic or normal neurons without any significant difference in intensity. The complex arborizing dendrites of dysplastic neurons were easily identified due to pronounced immunoreactivity within the somatodendritic regions. Immunoreactivity with the primary antibody against tau and ubiquitin was present in the normal-looking neurons as well as the dysplastic neurons. This study suggests that the dysplastic neurons in cortical dysplasia are accompanied by changes of cytoskeletal neurofilaments, and the immunohistochemical stains for NF-M/H, MAP2, tau, and ubiquigin are useful to detect them.

Giant cell tumor (GCT) occurs very unusually in the rib (less than 1% of GCT). We present the cytologic features of GCT of the rib. It showed multiple cellular clusters composed of characteristic, benign looking osteoclast-like multinucleated giant cells and fibroblast-like mononuclear cells. The multinucleated giant cells contained numerous nuclei (average, 30 to 40 per cell, which were closely packed. The nuclei in giant cells were remarkably uniform and round to oval. The mononuclear, neoplastic stromal cells were elongated and spindle-shaped, There was no cytologically malignant portion in the tumor.

PURPOSE: There have been repoty on radiological features of lower respiratory track infection in infants and children caused by RSV(respiratory syncytial virus) in KOREA. The aims of this study were to summarize radiological features of lower respiratory tract infection caused by common viral agents other than RSV and to find any specific radiological features which might provide clue to the etiologic diagnosis. MATERIALS AND METHODS: We retrospectively analyzed radiological features in 51 children with symptoms of lower respiratory tract infection and identification of viral agents(except RSV). They included parainfluenza (n=22), adenovirus(n=16), influenza A(n--11), influenza B(n=2) virus infections. The mean age of the patients was 23 months. RESULTS: Major radiological findings of viral lower respiratory tract infection were bilateral parahilar peribronchial infiltration(62%), bilateral overaeration(60%), atelectasis(59%)(segmental or subsegmental atelectasis(43%), Iobar atelectasis(16%)) and patchy or confluent consolidation(20%). Pleural effusion was seen in only one case and hilar adenopathy was not observed in any of them. In the cares of adeno virus, consolidation was seen in 5 cases(31%) including 3 cases919%) of extensive confluent consolidations and overaerations were less frequent findings(44%) than in other viruses. In 24 patients with radiological follow up for more than 1 week, consolidation improved most rapidly, while was persistent atelectasis. CONCLUSION: The major radiologic features in vital lower respiratory tract infection(except RSV) were overinflation, bilateral peribronchial infiltration and atelectasis. In adenoviral infection, confluent consolidations which are usually seen in bacterial pneumonia were more common findings than in other viral lower respiratory tract infections.
