Intravenous leiomyomatosis is a rare neoplasm characterized by intravenous growth of histologically benign smooth muscle cell tumor. We report a case of intravenous leiomyomatosis with right atrial extension in a 19-year-old woman. Various surgical techniques and approaches have been previously reported. In this case, the tumor was removed with a single-stage approach via laparotomy without cardiopulmonary bypass.

PURPOSE: The chemoembolization with Lipiodol and doxorubicin hydrochloride is used in patients with hepatocellular carcinoma. What condition is the ideal emulsion of Lipiodol and doxorubicin for excellent anticancer effect? METHOD AND MATERIALS: Microscopic evaluation was performed on the emulsions, which were varied with different specific gravities of doxorubicin solutions, degrees in mixing of the emulsion, and amount of Lipiodol. RESULT: 1. Maximal amount of doxorubicin solution was contained in Lipiodol droplets and the release of doxorubicin from the droplets were delayed, when specific gravity of doxorubicin was equal to that of Lipiodol (SG, 1.28). 2. The optimal therapertic ratio of Lipiodol and doxorubicin was 3:2 at least, as in the emulsion less than 3:2, unmixed free forms of doxorubicin solution were increased. 3. The emulsion mixed by pumping 50--100 times had smaller Lipiodol droplets and contained larger amount of doxorubicin solution in the droplets than by pumping 20 times. CONCLUSION: We recommend the emulsion with specific gravity of doxorubicin equal to Lipiodol (SG. 1.28), the ratio of Lipiodol and doxorubicin closo to 3:2, and the mixture prepased with puming 50--100 times.

PURPOSE: Mesenteric and omental cysts are uncommon lesions found all age groups. They elicit interest because of their unclear pathogenesis and confusing terminology. MATERIALS AND METHODS: CT findings of 12 case with mesenteric and omental cysts were described and compared with surgical and pathologic findings. RESULTS: In mesenteric and omental cyst, the histologic diagnoses were lymphangioma(7 cases), nonpancreatic pseudocyst(3 cases), mesothelial cyst(2 cases). Lymphangiomas were usually multiloculated with enhancing wall, located in the small bowel mesentery. And these cystic lesions were frequently attached to bowel and required resection of a bowel segment. In three cases of pseudocyst, thick and enhancing wall was shown in unilocular cyst. Two cases of mesothlial cyst were located in greater omenturn, showed very thin wall in unilocuation. CONCLUSION: The CT features of the mesenteric and omental cysts are fairly characteristic. Identification of lymphangioma, which shows a multilocuation and enhancing wall, is important due to frequent bowel resection in operative field.

Recently there has been a progressive increase of thoracolumbar fractures with neurologic symptoms. It has been thought that laminectomy increased instability and was therefore considered a contraindication. Currently, with the development of instrument for posterior stabilization, it is possible to perform posterior fusion and instrumentation, both with and without laminectomy. To compare the effect of neurologic recovery with and without laminectomy, we analyzed the clinical records of 38 patients with neurologic symptoms who were evaluated with plain radiographs and CT before and after surgery from 1989 to 1996 in Gyeong-Sang National University Hospital. We divided our cases into two groups, one group consisted open reduction with laminectomy and instrumentation with posterior fusion. The other group consisted of open reduction without laminectomy and instrumentation with posterior fusion. Twenty three of 38 were operated with open reduction and internal fixation with laminectomy and others were operated without laminectomy. The results were that both groups had improvement of neurologic symptoms after surgery and at follow-up. There was no significant statistical difference between the two groups. Depending on the time interval between injury and surgery, patients who were underwent emergency surgery had an marked improvement of neurologic symptoms. Except cases of complete paraplegia, incomplete paraplegic patients who were operated within 24 hours with laminectomy group had greater improvement than those without laminectomy. The improvement was statistically significant(P<0.05).

OBJECTIVE: The pathologic diagnosis of the astrocytoma has been primarily based on the histologic grading, however, there are some discrepancies among the pathologists on the tumor grading. Met protein, known as the hepatocyte growth factor receptor, is a transmembrane 190 kDa heterodimer with tyrosine kinase activity, encoded by c-met gene. Although c-Met protein is known to be expressed in a variety of tissues and plays important roles in signal transduction, the study on its expression related to clinicopathological prognostic parameters in brain tumor is rare. METHODS: We have evaluated c-Met protein expression in association with p53 and Ki-67 expression in 35 astrocytic tumors (15 diffuse astrocytomas: LGA, 11 anaplastic astrocytomas: AA, 9 Glioblastoma multiforme: GBM) using immunohistochemical method. RESULTS: c-Met immunoreactivity was observed in 2 LGA(13.3%), 5AA(45.5%), 4GBM cases (44.4%), respectively. p53 immunoreactivity was observed in 2 LGA(13.3%), 4AA(36.4%), 4GBM cases (44.4%), respectively. Ki-67 labelling index was 1.7+/-1.0% (LGA), 13.3+/-.2% (AA) and 18.0+/-.1% (GBM), respectively. Each c-Met expression and the Ki-67 labelling index were statistically correlated between low grade and anaplastic astrocytomas. The c-Met and p53 expression rate were not associated with increased Ki-67 labelling index. But, c-Met, p53, Ki-67 expression tended to increase with higher grade of malignancy. CONCLUSION: We conclude that c-Met expression may contribute to the invasiveness and tumor progression of the astrocytoma and c-Met expression is useful in discrimination between low grade astrocytoma and anaplastic astrocytoma.

PURPOSE: The therapeutic effects of amniotic membrane transplantation (AMT) contain anti-fibrosis, anti-inflammation and facilitation of epithelialization. Thus we investigated whether applying of amniotic membrane (AM) ointment could get the same effect as AMT. METHODS: Alkali burn was induced by applying 6 mm round filter paper which was soaked with 1 N NaOH, onto the central cornea for 60 seconds on both eyes of 10 white rabbits. Then we applied AM ointment on one eye and base ointment on the other eye, four times a day for 1 week. The corneas were harvested for histopathologic studies at 1 day and 3 weeks. Corneal opacity and thickness were measured in 3 days and 1, 2, 3 weeks. RESULTS: In the AM ointment applicated group, the number of the infiltrated PMNs (polymorp-honuclear cells) and apoptotic keratocytes were significantly less than that of the control group (P<0.05). The degree of lipid peroxidation and myofibroblast differentiation were less than those of the control group. Corneal opacity and corneal edema were less in AM ointment group than control group. CONCLUSIONS: AM ointment application after alkali burn is beneficial to reduce inflammation, keratocyte apoptosis and lipid peroxidation, and is considered to suppress corneal haze by these effects. Therefore, this report may be a basic study for the AM ointment research to treat recalcitrant keratitis.

The Galloway-Mowat syndrome, a rare inherited disorder, is characterized by congenital microcephaly with various neurological abnormalities and early onset of nephrotic syndrome with unresponsiveness to treatment, progressive deterioration in renal function and death in early lifetime. In this report, we describe a girl with microcephaly, seizures. and psychomotor retardation who developed nephrotic syndrome at 17 months of age.
