The clinical and pathological features of a paraganglioma arising in the cauda equina is described and compared with previous reports. The right microscopic fetures were similar to those of paragangliomas from other sites, with a 'Zellballen' pattern of cells containing arzyrophil granules. Immunohistocytochemical stains for neurone specific enolase, S-100 protein, cytokeratin were positive, but stains for glial fibrillary acidic protein were negative. Electron microscopy showed densely staining membrane-bound granules, cilia like structures and fibros bodies in the cytoplasm. The last two features only occur in paragangliomas from this site. The pathological findings suggest that paragangliomas in this site arise from pre-existing paraganglia, possibly of the visceral autonomic group.

Four children, with histopathologically confirmed posterior fossa primitive neuroectoderrnal tumors, were examined by plain radiography, computed tomography (CT) and cerebral angiography. The homogeneously well enhanced solid mass in the midline of the posterior fossa and hydrocephalus of various degree were seen on all CT scans. One case had calcifications and another case had low density areas in the tumor mass. Three cerebral angiograms showed vascular displacement without tumor vascularities. Unfortunately, these CT and angiography findings are and other tumors. when a well enhanced solid mass in the midline posterior fossa is seen on CT scan in children.

BACKGROUND: Many countries have been legally prescribing health warning messages on cigarette packages as a part of their national policy of smoking cessation. This study was designed to evaluate the effectiveness for smoking cessation of graphic health warning labels, and compare them with the existing health warning messages. METHODS: From February to December 2002, we surveyed 103 smokers who were college students of fine arts. After letfing them see the graphic health warning labels, the self recorded questionnaires were collected. RESULTS: The effectiveness for the smoking cessation of the existing health warning messages was evaluated low, despite its wide recognition. But there was no difference between the visual effect and the effectiveness for the smoking cessation of the graphic health warning labels. The graphic health warning labels were more effective for the smoking cessation than the existing health warning messages, and it was the same in the subgroup analysis such as sex, degree of recognition of disease, and non- smoking planning. CONCLUSION: To quit smoking, it is reasonably concluded that the graphic health warning labels on cigarette packages was very effective. Hereafter, it is recommended more useful designs of graphic health warning labels be developed.

The Finnish type of Congenital Nephrotic Syndrome is characterized by large placenta, early manifestation, growth and developmental delay and resistance to treatment. Authors experienced a case of characteristic Finnish type of Congenital Nephrotic Syndrome in a girl, who was admitted to the Pediatric Department of KHUH at 2 1/1 months of age because of generalized edema and abdominal distension and died of pneumonia at 5 1/2 months of age. The diagnosis was made by birth history, clinical manifestation, laboratory findings and finally by the autopsy findings, Literatures are reviewed briefly.

The effect of DMSO and sodium butyrate on the production of recombinant hepatitis A virus (HAV) capsid protein VP1 was evaluated and optimized in the culture of stably transfected Drosophila melanogaster S2 cells using culture plates and spinner flasks. The effect of DMSO and sodium butyrate was also evaluated to improve the recombinant VP1 production in stably transfected Drosophila S2 cells. A production level of 0.88 mg of recombinant VP1/liter was obtained in the culture-plate culture of stably transfected S2 cells at 6 days after induction with 0.5 mM CuSO4. The supplements of 2% DMSO and 10 mM sodium butyrate at 4 days post-inoculation increased recombinant VP1 accumulation by 141 and 104%, respectively, resulting in 2.17 and 1.7 mg/liter of recombinant VP1 production. In spinner flasks, recombinant VP1 production reached maximum level at 9 days after induction with 0.5 mM CuSO4, with approximately 4.96 mg/liter of recombinant VP1 production level. When 2% DMSO or 10 mM sodium butyrate was added at 5 days post-inoculation, the recombinant VP1 production was increased to 8.35 and 5.85 mg/liter, respectively. However, the synergistic effects of DMSO and sodium butyrate were not observed. These results indicate that DMSO and/or sodium butyrate can be successfully used to improve the recombinant HAV VP1 production in culture plates and spinner flasks.

BACKGROUND/AIMS: Tuberculous peritonitis is still a very important cause of exudative ascites in Korea. We analized the clinical features and laparoscopic findings in patients with tuberculous peritonitis diagnosed by laparoscopy. METHODS: We studied 51 patients who had tuberculous peritonitis confirmed by laparoscopic biopsy from 1980 to 2000, in retrospective method. RESULTS: The ratio of male to female was 1:2. The peak incidence was between 21 and 40 years of age. The mean duration of symptoms is 60 days. The most frequent chief complaints and physical findings was abdominal fullness (88.2%) and shifting dullness (94.1 %). Involvement of other organs included pulmonary tuberculosis (27.4%), cervical tuberculous lymphadenitis (3.9%). The mean ascitic fluid protein concentration was 4.9 gm/dL, mean WBC count 1,240/mm3 and lymphocyte dominant exudate 88.2%. AFB smear was positive only one patient (2.0%). Tuberculous nodules on laparoscopy were noted in all of the patients. Histolologic findings were caseating granuloma (72.6%), non-caseating granuloma (19.6%) and nonspecific inflammation (7.8%). Tissue AFB stain was positive 10 patients (19.6%). CONCLUSIONS: Tuberculous peritonitis shows nonspecific clinical features. Therefore, laparoscopic examination with biopsy is the most useful method to make differential diagnosis of patients who are suspected tuberculous peritonitis.

Acinar cell carcinoma of the pancreas is a rare tumor that constitutes 1~2% of all pancreatic cancers. The clinical and radiologic findings are inconclusive when diagnosing this disease. Acinar cell carcinoma progresses rapidly and metastasizes early, resulting in a poor prognosis. A 41-year-old man was admitted for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography (PET)-CT showed a splenic mass involving the pancreatic tail with increased 18F-fluorodeoxyglucose (18F-FDG) uptake. A primary radical distal pancreatectomy and splenectomy were carried out. The pathology revealed acinar cell carcinoma of the pancreas. Three months later, a gastric recurrence was detected and a total gastrectomy was performed. Four months later, multiple hepatic metastases were found and a left hepatectomy was carried out. During treatment with capecitabine, no evidence of tumor progression was observed for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma that did not progress for 14 months with capecitabine treatment.

Primary retroperitoneal mucinous cystadenocarcinoma is a very rare malignancy, and little is known concerning its pathogenesis, optimal treatment, and prognosis. A 29-year-old pregnant woman (21 weeks) presented with abdominal discomfort. CA 19-9, CA 125, and CEA were normal. Abdominal CT scanning revealed a 19x15x13 cm retroperitoneal tumor. Exploratory laparotomy and tumor excision were performed. Mucinous retroperitoneal implants were removed as completely as possible. Histologically, the tumor showed focal areas of capsular invasion, but free resection margins. The uterus and both ovaries were normal in appearance. No adjuvant therapy was pursued. Six months later, peritoneal and bilateral ovarian metastases were discovered.Hence, we report the details of this case of primary retroperitoneal mucinous cystadeno-carcinoma and present a review of the literature.

Acinar cell carcinoma is a rare tumor that represents 1~2% of all pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease. Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-old man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased 18F-fluorodeoxyglucose (FDG) uptake. Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the pancreas. The patient underwent a total gastrectomy three months later because of gastric recurrence. Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy. During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabine.
