Primary ampullary carcinoma is one of rare gastrointestinal malignancies which can be diagnosed by ERCP and endoscopic biopsy. However, sometimes it is difficult to comfirm the diagnosis when the tumor is not exposed out of orifice of ampulla. Recently, we diagnosed early stage ampullary carcinoma using endoscopic sphincetrotomy for the exposure of tumor in 54 year old woman ia whom ERCP revealed rather impacted stone like filling defect in distal common bile duct. we describe a case of papillary adenocarcinoma of the ampulla of Vater diagnosed by edoscopic sphincterotomy.

OBJECTIVES: The aim of this study was to compare the osteogenic effects of demineralized dentin matrix (DDM) combined with recombinant human bone morphogenetic protein-2 (rhBMP-2) in rabbit calvarial defects with DDM and anorganic bovine bone (ABB) combined with rhBMP-2. MATERIALS AND METHODS: Four round defects with 8-mm diameters were created in each rabbit calvaria. Each defect was treated with one of the following: 1) DDM, 2) ABB/rhBMP-2, or 3) DDM/rhBMP-2. The rhBMP-2 was combined with DDM and ABB according to a stepwise dry and dip lyophilizing protocol. Histological and microcomputed tomography (µCT) analyses were performed to measure the amount of bone formation and bone volume after 2- and 8-week healing intervals. RESULTS: Upon histological observation at two weeks, the DDM and ABB/rhBMP-2 groups showed osteoconductive bone formation, while the DDM/rhBMP-2 group showed osteoconductive and osteoinductive bone formation. New bone formation was higher in DDM/rhBMP-2, DDM and ABB decreasing order. The amounts of bone formation were very similar at two weeks; however, at eight weeks, the DDM/rhBMP-2 group showed a two-fold greater amount of bone formation compared to the DDM and ABB/rhBMP-2 groups. The µCT analysis showed markedly increased bone volume in the DDM/rhBMP-2 group at eight weeks compared with that of the DDM group. Notably, there was a slight decrease in bone volume in the ABB/rhBMP-2 group at eight weeks. There were no significant differences among the DDM, ABB/rhBMP-2, and DDM/rhBMP-2 groups at two or eight weeks. CONCLUSION: Within the limitations of this study, DDM appears to be a suitable carrier for rhBMP-2 in orthotopic sites.

We herein describe a 70-year-old woman who presented with respiratory failure due to extensive lung adenocarcinoma. Despite advanced disease, care in the intensive care unit with ventilator support was performed because she was a newly diagnosed patient and was considered to have the potential to recover after cancer treatment. Because prompt control of the cancer was needed to treat the respiratory failure, empirical treatment with an oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor was initiated before confirmation of EGFR-mutant adenocarcinoma, and the patient was successfully treated. Later, EGFR-mutant adenocarcinoma was confirmed.

BACKGROUND: Inflammatory cytokines play an important role in human immune responses to malaria, although the role of these mediators in pathogenesis is unclear. In this study, we evaluated changes in cytokine levels following chemotherapy, and determined whether cytokine levels in serum correlated with the hematological parameters in the Korean vivax malarial patients. METHODS: The study population was composed of 31 patients in Inje University Ilsan Paik Hospital who were diagnosed with Plasmodium vivax infection. Cytokine profiles, including tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, and IL-10 levels, were assessed in serum samples obtained from the malaria patients three times, at the time of diagnosis (stage I) and after treatment with hydroxychloroquine (stage II) and primaquine (stage III). The level of each cytokine was measured using commercially available serum-based ELISA kits. Hematological parameters were simultaneously measured using a hematology autoanalyzer. RESULTS: At thetime of diagnosis, the TNF-alpha (mean, 62.9 pg/mL), IL-6 (mean, 45.5 pg/mL), and IL-10 (mean, 237.7 pg/mL) levels in the malaria patients were higher than the reference values. After treatment with hydroxychloroquine, these levels (TNF-alpha, P<0.01; IL-6, P<0.05; IL-10, P<0.01) significantly decreased to near-normal levels. Significant positive correlations were observed among the cytokine levels, but not between the cytokine levels and other hematological parameters. CONCLUSIONS: In this study, TNF-alpha, IL-6, and IL-10 levels increased at the time of diagnosis and rapidly decreased to normal levels after treatment the levels of these cytokines did not correlate with other hematological parameters.

ABSTRACT: Apoptosis of osteosarcoma cells induced by bile duct derivates, HS-1200 was investigated with relation to mitochodria. HS-1200 induced cytochrome c and Smac/DIABLO release from mitochondria which are major factors related to apoptosis. In these apoptosis processes, release of cytochrome c was not blocked by caspase inhibitor, but release of Smac/DIABLO was blocked. BKA, a kind of PTP (permeablity transition pore) inhibitor, did not block both of them. Interestingly, the alteration of MMP was not observed by means of using JC-1 dye. Although MitoTracker, DiOC-6 and Rhodamine123 were used to confirm previous results, the decrease of MMP was not observed. In order to investigate whether this phenomenon is apoptosis-specific or cell-specific process, genistein was added to cells which usually decreased MMP. After adding genistein, MMP was not decreased, suggesting this phenomenon is cell-specific process. Conclusionally, HS-1200 induced apoptosis of osteosarcoma cells via mitochondria, cytochrome c and Smac/DIABLO were released from mitochondria without decrease of MMP. The release of Smac/DIABLO was dependent of caspase.

Vivax malaria reemerged in the Republic of Korea in 1993. Vivax malaria is generally a benign disease with few severe complications. Even in the worldwide literature, there is only a small number of case reports on severe complications in vivax malaria. We report a unique case of P. vivax infection complicated by seizure and shock. A 58 year-old male showed generalized tonic-clonic seizure and shock after P. vivax infection. The species of malarial parasite was identified using peripheral blood film examination and polymerase chain reaction (PCR). He successfully recovered after treatment with hydroxychloroquine.

Low-viscosity composite resins may produce better sealed margins than stiffer compositions (Kemp-Scholte and Davidson, 1988; Crim, 1989). Flowable composites have been recommended for use in Class V cavities but it is also controversial because of its high rates of shrinkage. On the other hand, in the study comparing elastic moduli and leakage, the microfill had the least leakage (Rundle et al. 1997). Furthermore, in the 1996 survey of the Reality Editorial Team, microfills were the clear choice for abfraction lesions. The purpose of this study was to evaluate the microleakage of 6 compostite resins (2 hybrids, 2 microfills, and 2 flowable composites) with and without load cycling. Notch-shaped Class V cavities were prepared on buccal surface of 180 extracted human upper premolars on cementum margin. The teeth were randomly divided into non-load cycling group (group 1) and load cycling group (group 2) of 90 teeth each. The experimental teeth of each group were randomly divided into 6 subgroups of 15 samples. All preparations were etched, and Single bond was applied. Preparations were restored with the following materials (n=15): hybrid composite resin [Z250(3M Dental Products Inc. St.Paul, USA), Denfil(Vericom, Ahnyang, Korea)], microfill [Heliomolar RO(Vivadent, Schaan, Liechtenstein), Micronew(Bisco Inc. Schaumburg, IL, USA)], and flowable composite [AeliteFlo(Bisco Inc. Schaumburg, IL, USA), Revolution(Kerr Corp. Orange, CA, USA)]. Teeth of group 2 were subjected to occlusal load (100N for 50,000 cycles) using chewing simulator(MTS 858 Mini Bionix II system, MTS Systems Corp., Minn. USA). All samples were coated with nail polish 1mm short of the restoration, placed in 2% methylene blue for 24 hours, and sectioned with a diamond wheel. Enamel and dentin/cementum margins were analyzed for microleakage on a sclale of 0 (no leakage) to 3 (3/3 of wall). Results were statistically analyzed by Kruscal-Wallis One way analysis, Mann-Whitney U-test, and Student-Newmann-Keuls method. (p=0.05) RESULTS: 1. There was significantly less microleage in enamel margins than dentinal margins of all groups. (p<0.05) 2. There was no significant difference between six composite resin in enamel margin of group 1. 3. In dentin margin of group 1, flowable composite had more microleakage than others but not of significant differences. 4. There was no significant difference between six composite resin in enamel margin of group 2. 5. In dentin margin of group 2, the microleakage were R>A=H=M>D>Z. But there was no significant differences. 6. In enamel margins, load cycling did not affect the marginal microleakage in significant degree. 7. In dentin margins, load cycling did affect the marginal microleakage only in Revolution. (p<0.05)

Morganella morganii is a facultative gram-negative and anaerobic rod. It may be a cause of devastating infections in neonates and immunocompromised hosts. Some bacterial infections such as Clostridium and Vibrio are associated with hemolysis. However, massive hemolysis caused by M. morganii sepsis has not yet been reported. We observed a 59-yr-old man who had chemotherapy-induced neutropenia and was found to have massive hemolysis and metabolic acidosis due to sepsis. He died 6 hr after admission in spite of aggressive treatment. Two sets of blood cultures revealed the growth of M. morganii. We report here that M. morganii sepsis can cause fatal massive hemolysis leading to death.
