Fetus papyraceus, also called fetus compressus, is a mummified and compressed fetus as a result of fetal death during pregnancy. It is always associated with twin pregnancy, and the other litter is usually alive to compress the dead feuts. The cause of death of the fetus is not always clear. Recently we had a case of fetus papyraceus from a 25-year-old woman, which we thought most probably caused by velamentous insertion of the umbilical cord into the dividing membrane of the placenta, resulting fetal death and subsequently becoming fetus papyraceus.

C-erbB-2 oncoprotein has been known to act as growth factor receptor responsible for the regulation of cellular growth, proliferation and differentiation and has been demonstrated in a number of cancers by immunohistochemical as well as matrix blotting techniques. Breast and ovarian cancer patients, whose tumor cells have amplification or overexpression of this oncoprotein, have been suggested to have worse prognosis. Yet, there are only a few studies on c-erbB-2 oncoprotein expression in transitional cell carcinoma(TCC) of the bladder. The aim of this study was to examine c-erbB-2 oncoprotein expression in bladder cancer to assess its potential as a useful prognostic marker in transitional cell carcinoma of the bladder. Deparaffinized tumor specimens from 42 patients with TCC of the bladder and 3 normal bladder tissue specimens were utilized. C-erbB-2 oncoprotein expression was detected by immunohistochemical analysis and then correlated with conventional prognostic variables such as histologic tumor grade, stage and DNA ploidy. In addition, we related the expression of c-erbB-2 oncoprotein to indicators of cellular proliferative activities such as proliferating cell nuclear antigen(PCNA), mean number of silver nucleolar organizer regions(AgNORs) per nucleus, flow cytometric S-phase fraction(CPF) and proliferation index(PI). The incidence of c-erbB-2 oncoprotein expression in Ash grade IV TCC of bladder was higher than that in Ash grade II and III (Chi-square test, p<0.05). The incidence of positive immunoreaction was higher in cases with muscle invasion and metastasis than in superficial tumors with statistical significance(p<0.05). In addition, statistical significant correlation was noted between c-erbB-2 oncoprotein expression and PCNA expression rate. But there were no significant differences in c-erbB-2 oncoprotein expression to DNA ploidy, PI nor SPF by flow cytometry and mean number of AgNORs per nucleus. The results of this study suggests that the c-erbB-2 oncoprotein together with other predictive parameters may serve to provide a phenotypic profile which permits more accurate forecasting of bladder cancer behavior and may prove to be useful in the future as an important guide to specific anti-tumor therapy.

PURPOSE: The aim of the study was to compare the clinical characteristics in emergency endotracheal intubation procedures between non-elderly and elderly patients. METHODS: Data for airway registry, which were collected in two emergency departments (ED) between April 2006 and March 2010, were retrospectively reviewed. The airway registry data included patient's demographic information and variables such as Cormack-Lehane grade, 3-3-2 finger analysis, success rate, the number of attempts at intubation, complications of intubation, and clinical outcomes after intubation. RESULTS: A total of 1,457 patients were enrolled. The mean age of the patients was 62.2+/-15.7 and 62.1%(n=905) were male. A total of 726(49.8%) patients were classified as being in the elderly intubation group(> or =65 years). Cormack-Lehane grade, 3-3-2 finger analysis, the relationship between the number of attempts and success rate, the relationship between Cormack-Lehane classification and success rate, complications, and clinical outcomes after intubation showed no significant difference between elderly and non-elderly groups. CONCLUSION: Anatomical structures related to endotracheal intubation, the process and clinical outcomes of elderly patients are not different than for non-elderly adult patients. However, considering the lower physiologic reservoir and higher comorbidities of elderly patients, a more vigorous approach to emergency airway management in the elderly is needed.

A histopathological study was carried out on the duodenum of mice and rats experimentally infected by F. seoulensis. Each mouse was infected wit 500 metacercariae and killed after 1, 2, 3 days, 1 and 2 weeks from infection. Each rat was given 1,000 metacercariae and was examined after 1, 2, and 4 weeks from infection. The duodenal tissue sections of mice and rats were stained with hematoxylin and eosin, and PAS stained for the rats of 1 week group. The pathological findings are summarized as below. There were no differences in mucosal findings between the mice and the rats, adn between the location of duodenum, 1 and 5 cm distal to the pylorus. Each worm embraced a villus exclusively with its foliate forebody which was inserted into the intervillous spaces. The fluke pinched villous epithelia using its oral and ventral suckers. The tribocytic organ destroyed the villous epithelia deeply up to the stroma after 3 days from infection. Apparent villous changes were observed in the mice after 3 days from infection. Villous changes were shortening, widening, blunting or fusion. The villous stroma showed edema, microscopic hemorrhage, capillary congestion, dilatation of lymphatics and inflammatory cell infiltration. The cells were lymphocytes, plasma cells, eosinophils and giant cells. Rarely submucosal and transmural inflammation was encountered.

Bacterial lipopolysaccharide (LPS) plays a major role in stimulating the synthesis and release of the principal osteoclast-activating cytokines, namely, interleukin 1 and tumor necrosis factor-alpha from immune cells. Although monocytes/macrophages are the main producers of these cytokines, recent evidence has indicated that polymorphonuclear leukocytes (PMN) have the ability to release IL-1 and TNF-alpha. Calcium hydroxide has been shown to be an effective medicament in root canal infections, reducing the microbial titre within the canal. It has been proposed that the therapeutic effect of Ca(OH)2 may also be the result of direct inactivation of LPS. The purpose of this study was to investigate whether treatment of Porphyromonas endodontalis LPS with calcium hydroxide alters its biological action as measured by human PMN secretion of IL-1 and TNF-alpha, and it was compared with Escherichia coli LPS. P. endodontalis ATCC 35406 was cultured in anaerobic condition, and LPS was extracted using the hot-phenol water extraction method and purified. Purchased E. coli LPS was also purified. 100 microg/ml of each LPS in pyrogen free water were incubated with 25mg/ml Ca(OH)2 at 37degrees C for 7 days. The supernatants were subjected to ultrafiltration, and the isolates were lyophilized and weighed. PMNs were obtained from peripheral blood by centrifugation layered over Lymphoprep. The cells were resuspended (4x106 cells/ml) in RPMI 1640 followed by treatment with various concentrations of LPS (0, 0.1, 1, 10microg/ml) for 24 hours at 37degrees C in 5% CO2 incubator. The supernatants of cells were collected and the levels of IL-1alpha, IL-1beta and TNF-alpha were measured by enzyme-linked immunosorbent assay. The results were as follows; 1. The levels of IL-1alpha, IL-1beta, TNF-alpha from PMN treated with each LPS were significantly higher than those released from unstimulated PMN of the control group (p<0.05). 2. The levels of all three cytokines released from PMN stimulated with each calcium hydroxide treated LPS were significantly lower than those released from PMN stimulated with each untreated LPS (p<0.05), while they were not significantly different from those released from unstimulated PMN of the control group (p>0.05). 3. The levels of secretion for all three cytokines were affected in a dose-dependent manner in PMN stimulated with each LPS (p<0.05), but not in PMN stimulated with each calcium hydroxide treated LPS (p>0.05). 4. The levels of all three cytokines released from PMN stimulated with P. endodontalis LPS were significantly lower than those released from PMN stimulated with E. coli LPS (p<0.05).

PURPOSE: The aim of this study was to validate the Glasgow-Blatchford score and the pre-endoscopic Rockall score to assess their ability to predict the presence of active bleeding in emergency department patients with suspected upper gastrointestinal bleeding. METHODS: We reviewed and extracted data from electronic medical records on patients presenting with a suspicion of acute upper gastrointestinal bleeding at our emergency department from January 1, 2012 to December 31, 2012. For each patient we calculated the Glasgow-Blatchford score and the pre-endoscopic Rockall score. Discriminative ability of the scoring systems for predicting active bleeding was evaluated by receiver operator characteristic (ROC) curve analysis. RESULTS: We identified 636 patients with upper gastrointestinal bleeding. There were 118 (18.6%) patients with active bleeding and 520 (81.8%) patients with need for intervention. The ROC curve analysis showed poor discriminative ability of the Glasgow-Blatchford score and the pre-endoscopic Rockall score for determining the presence of active bleeding (area under the curve (AUC)=0.546, 95% confidence interval (CI) 0.490-0.602 vs. 0.576, 95% CI 0.523-0.630; p=0.34). The sensitivity and the specificity of the two scoring systems were suboptimal. However, the Glasgow-Blatchford score outperformed the pre-endoscopic Rockall score in predicting the need for clinical intervention (AUC=0.867, 95% CI 0.831-0.903 vs. 0.698, 95% CI 0.643-0.754; p<0.001). CONCLUSION: The Glasgow-Blatchford score was superior in predicting the need for intervention in emergency department patients with suspected gastrointestinal hemorrhage. However, these clinical decision rules may be insufficient to predict the presence of active bleeding.
