This study was conducted to evaluate the accuracy of the official death registry in rural area. The base data used for the study was 379 deaths registered during the period of 1993 and 1994 in 4 rural townships of Chonnam Province. The interview survey for cause-of-death was performed on the next of kin and/or neighbor. Additional medical informations were collected from hospitals and medical insurance associations for the purpose of verification. The underlying cause-of-death of 278 cases presumed by the survey was compared to the cause on official death registry. There was a prominent disagreement of cause-of-death between the survey data and the registry data(agreement rate: 38.9~44.6%%, according to disease classification method). These results may be caused by extremely low rates of physicians' certification, which were mostly confined to the poisoning and injury. Symptoms, signs, and ill defined conditions on death registry could be classified into circulatory disease(32.3%), neoplasm(21.2%), digestive disease(7.l%), injury and poisoning(7.l%) and so on. These results suggest that careful attention and verification be required on utilization of death registry data in rural area.

Desmoplastic small round cell tumor (DSRCT) is a rare and highly aggressive neoplasm. The cytological diagnosis of this tumor has only been reported in a few cases. In most of these cases, the diagnosis was made using fine-needle aspiration cytology. Most DSRCTs resemble disseminated carcinomatoses in their clinical manifestation as well as cytomorphologically, even in young-adult patients. These authors report a case of using peritoneal-washing and pleural-effusion ThinPrep cytology to diagnose DSRCT, with extensive glandular differentiation and mucin vacuoles. We found that fibrillary stromal fragment, clinical setting, and adjunctive immunocytochemical staining were most helpful for avoiding misdiagnosis.

A 29-year-old pregnant woman with recurrent pericardial effusion and a cardiac tumor, diagnosed as an angiosarcoma, was treated with surgical resection of the tumor followed by radiotherapy. Immediately after completion of radiotherapy, she developed bilateral breast masses, which were also confirmed as angiosarcomas. We thought this might be the first case of bilateral angiosarcoma of the breast metastasizing to heart mimicking a primary cardiac angiosarcoma, although we could not conclude with certainty that angiosarcoma of the heart was not the primary site.

Paragonimiasis typically results from the consumption of raw or improperly cooked crustacea, especially crabs and crayfish. Although previously endemic in Korea, the prevalence of this disease decreased in the early 1970s because of educational campaigns and fewer intermediate hosts as a result of ecological changes. Recently, we were presented with a family where all members were infected with Paragonimus after ingestion of Kejang (= drunken crab). The mother was hospitalized for general myalgia and weakness first, followed by the father, who was hospitalized for dyspnea 2 month later. After the parents were diagnosed with paragonimiasis, we recommended their daughter to visit our hospital for a checkup, because they all had eaten freshwater crabs soaked in soybean sauce. She complained of generalized myalgia, fever, and pleuritic pain, and was also diagnosed with paragonimiasis. Peripheral blood of the 3 patients revealed hypereosinophilia, and computed tomography (CT) scans of their chests showed pleural effusion. The results of antibody tests by ELISA were positive for paragonimiasis. We report here the case series of familial paragonimiasis in a modern urban city, rather than in a typical endemic area.

Primary central nervous system lymphoma (PCNSL) is an aggressive non-Hodgkin's lymphoma (NHL), usually composed of diffuse large B-cells. Although rituximab is known for its curative effect on B-cell NHL, data on the use of intrathecal rituximab for PCNSL are limited. In this report, we present two patients showing relapsed PCNSL with lymphomatous meningitis. Both patients were refractory to conventional methotrexate-based intrathecal chemotherapy. However, after intrathecal rituximab with or without conventional intrathecal chemotherapy, both patients showed stable disease on magnetic resonance brain imaging and cerebrospinal fluid analysis. There were no serious adverse events during each of 3 and 6 cycles with intrathecal rituximab immunotherapy.

Histiocytic sarcoma (HS) is a very rare neoplasm that often shows an aggressive clinical course and systemic symptoms, such as fever, weight loss, adenopathy, hepatosplenomegaly and pancytopenia. It may present as localized or disseminated disease. We describe here a 63-yr-old male who manifested systemic symptoms, including fever, weight loss and generalized weakness. Abdominal and chest computed tomography failed to show specific findings, but there was suspicion of multiple bony changes at the lumbar spine. Fusion whole body positron emission tomography, bone scan and lumbar spine magnetic resonance imaging showed multiple bone lesions, suggesting a malignancy involving the bone marrow (BM). Several BM and bone biopsies were inconclusive for diagnosis. Necropsy showed replacement of the BM by a diffuse proliferation of neoplastic cells with markedly increased cellularity (95%). The neoplastic cells were positive for lysozyme and CD68, but negative for T- and B-cell lineage markers, and megakaryocytic, epithelial, muscular and melanocytic markers. Morphologic findings also distinguished it from other dendritic cell neoplasms.

Acquired amegakaryocytic thrombocytopenia (AAMT) is an unusual disease characterized by severe thrombocytopenia resulting from a marked decrease in bone marrow megakaryocytes. Various pathogenic mechanisms have been suggested, and several treatments have been tried, with varying outcomes. In some case reports, cyclosporine and anti-thymocyte globulin have had good clinical results in the treat of AAMT. There are few reports on the treatment of relapsed AAMT with cyclosporine. We report a patient with relapsed AAMT who was treated successfully with an additional course of cyclosporine. The initial remission was achieved with cyclosporine 4 years earlier and a second remission was induced by cyclosporine. Cyclosporine may be effective for relapsed AAMT that previously responded to cyclosporine.

BACKGROUND: It is known that propofol protects myocardium against a global ischemia-reperfusion injury in the isolated rat heart model. The aim of this study was to investigate whether propofol, at a clinically relevant concentration infused during the peri-ischemic period, also provides a protective effect against a regional myocardial ischemia-reperfusion injury in vivo. METHODS: Rats were subjected to 25 minutes of coronary artery occlusion followed by 24 hours of reperfusion. Propofol or intralipid was administrated during 35 minutes starting 5 minutes before the onset of ischemia until 5 minutes after the onset of reperfusion. A micromanometer catheter was advanced into the left ventricle and the hemodynamic function was evaluated. The infarct size was determined by triphenyltetrazolium staining after 24 hours of reperfusion. RESULTS: Propofol administration during the peri-ischemic period demonstrated protective effects on hemodynamic function and infarct size reduction. In the control group, the peak rate of the ventricular pressure increase (+dP/dt(max))(P = 0.0001) and the peak rate of the intraventricular pressure decline (-dP/dt(max))(P = 0.0001) were significantly decreased compared to the sham group. In the propofol group, the +dP/dt(max) (P = 0.003) and -dP/dt(max) (P = 0.002) were significantly improved compared to the control group. The infarct size was 47.6% of the area at risks in the control group, and was reduced markedly by administration of propofol during the peri-ischemic period to 26.2% in the propofol group (P = 0.004). CONCLUSIONS: Propofol, at a clinically relevant concentration infused during the peri-ischemic period, have protective effect after regional myocardial ischemia-reperfusion injury in an in vivo rat heart model.

Acute recurrent pancreatitis has a variety of etiologies. We experienced a case of a tumor-forming pancreatitis in a 49 year old Korean woman who also had pancreatic intraepithelial neoplasm III (PanIN-III), and this manifested just like recurrent pancreatitis. She had a history of recurrent pancreatitis. She was found to have an early stage of pancreatic cancer via computed tomography and magnetic resonance cholangiopancreatography. EUS guided fine needle aspiration (FNA) showed only many acinar cells of the pancreas. But due to the possibility of her having pancreatic carcinoma, she underwent distal pancreatectomy and splenectomy with lymph node dissection. Pathologically, the tumor of the pancreatic body showed secondary changes with focal fibrosis from the localized chronic pancreatitis. PanIN-III was observed in the pancreatic duct within the tumor, and there were no cancerous findings in the 13 dissected lymph nodes.

BACKGROUND/AIMS: Rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy (R-CHOP) has improved survival in patients with diffuse large B-cell lymphoma (DLBCL) and weakened the prognostic power of the international prognostic index (IPI). We evaluated the efficacy of the IPI and revised IPI (R-IPI) in patients with DLBCL who were treated with R-CHOP, focusing on extranodal site number (ENS) because extranodal involvement occurs frequently in Koreans. METHODS: A total of 126 R-CHOP-treated patients with stage III/IV DLBCL were analyzed. We performed a retrospective analysis of the clinicopathologic factors and verified the predictive power of the standard IPI and R-IPI. Various numbers of extranodal sites were analyzed for further stratification, and we set the extranodal site-modified IPI (E-IPI) as the IPI when the number of extranodal sites was stratified as < 3 vs. > or = 3. RESULTS: A univariate analysis showed that ENS was associated with complete response (CR, p = 0.04), event-free survival (EFS, p = 0.01), and overall survival (OS, p < 0.001) when the ENS cut-off was set at > or = 3. A multivariate analysis revealed that an ENS > or = 3 remained associated with EFS (p < 0.01; hazard ratio [HR], 2.60; 95% confidence interval [CI], 1.29 to 5.26) and OS (p < 0.01; HR, 3.52; 95% CI, 1.68 to 7.35). The IPI was effective for determining prognosis in terms of OS (p = 0.04) but not EFS (p = 0.17). The R-IPI was effective in terms of both variables (p = 0.02 and 0.04, respectively), as was the E-IPI (p = 0.01 and 0.001, respectively). CONCLUSIONS: An ENS < 3 vs. > or = 3, rather than the original < 2 vs. > or = 2, was the most significant prognostic factor for EFS and OS. All three indices were predictive, but only the E-IPI identified the high-risk group of R-CHOP-treated Korean patients with disseminated DLBCL.
