    Local weather factors are widely considered to influence the transmission of infectious gastroenteritis. Few studies, however, have examined the non-stationary relationships between global climatic factors and transmission of infectious gastroenteritis. We analyzed monthly data for cases of infectious gastroenteritis in Fukuoka, Japan from 2000 to 2012 using cross-wavelet coherency analysis to assess the pattern of associations between indices for the Indian Ocean Dipole (IOD) and El Niño Sou...

    Local weather factors are widely considered to influence the transmission of infectious gastroenteritis. Few studies, however, have examined the non-stationary relationships between global climatic factors and transmission of infectious gastroenteritis. We analyzed monthly data for cases of infectious gastroenteritis in Fukuoka, Japan from 2000 to 2012 using cross-wavelet coherency analysis to assess the pattern of associations between indices for the Indian Ocean Dipole (IOD) and El Niño Southern Oscillation (ENSO). Infectious gastroenteritis cases were non-stationary and significantly associated with the IOD and ENSO (Multivariate ENSO Index [MEI], Niño 1 + 2, Niño 3, Niño 4, and Niño 3.4) for a period of approximately 1 to 2 years. This association was non-stationary and appeared to have a major influence on the synchrony of infectious gastroenteritis transmission. Our results suggest that non-stationary patterns of association between global climate factors and incidence of infectious gastroenteritis should be considered when developing early warning systems for epidemics of infectious gastroenteritis.

    Transmissible gastroenteritis coronavirus (TGEV) is one of the most destructive agents, responsible for the enteric infections that are lethal for suckling piglets, causing enormous economic loss to the porcine fostering industry every year. Although it has been known that TGEV spiker protein is essential for the viral entry for many years, the detail knowledge of the TGEV fusion protein core is still very limited. Here, we report that TGEV fusion core (HR1-SGGRGG-HR2), in vitro expressed in GST prokaryotic expression system, shares the typical properties of the trimer of coiled-coil heterodimer (six α-helix bundle), which has been confirmed by a combined series of biochemical and biophysical evidences including size exclusion chromatography (gel-filtration), chemical crossing, and circular diagram. The 3D homologous structure model presents its most likely structure, extremely similar to those of the coronaviruses documented. Taken together, TGEV spiker protein belongs to the class I fusion protein, characterized by the existence of two heptad-repeat (HR) regions, HR1 and HR2, and the present knowledge about the truncated TGEV fusion protein core may facilitate in the design of the small molecule or polypeptide drugs targeting the membrane fusion between TGEV and its host

    A recombinant transmissible gastroenteritis coronavirus (rTGEV) in which E gene was deleted (rTGEV-ΔE) has been engineered. This deletion mutant only grows in cells expressing E protein (E + cells) indicating that E was an essential gene for TGEV replication. Electron microscopy studies of rTGEV-ΔE infected BHK-pAPN-E - cells showed that only immature intracellular virions were assembled. These virions were non-infectious and not secreted to the extracellular medium in BHK-pAPN-E - cells. RNA and protein composition analysis by RNase-gold and immunoelectron microscopy showed that rTGEV-ΔE virions contained RNA and also all the structural TGEV proteins, except the deleted E protein. Nevertheless, full virion maturation was blocked. Studies of the rTGEV-ΔE subcellular localization by confocal and immunoelectron microscopy in infected E - cells showed that in the absence of E protein virus trafficking was arrested in the intermediate compartment. Therefore, the absence of E protein in TGEV resulted in two actions, a blockade of virus trafficking in the membranes of the secretory pathway, and prevention of full virus maturation

    Highlights: •TGEV infection induced ROS accumulation. •ROS accumulation is involved in TGEV-induced mitochondrial integrity impairment. •ROS is associated with p53 activation and apoptosis occurrence in TGEV-infected cells. -- Abstract: Transmissible gastroenteritis virus (TGEV), an enteropathogenic coronavirus, causes severe lethal watery diarrhea and dehydration in piglets. Previous studies indicate that TGEV infection induces cell apoptosis in host cells. In this study, we investigated the roles and regulation of reactive oxygen species (ROS) in TGEV-activated apoptotic signaling. The results showed that TGEV infection induced ROS accumulation, whereas UV-irradiated TGEV did not promote ROS accumulation. In addition, TGEV infection lowered mitochondrial transmembrane potential in PK-15 cell line, which could be inhibited by ROS scavengers, pyrrolidinedithiocarbamic (PDTC) and N-acetyl-L-cysteine (NAC). Furthermore, the two scavengers significantly inhibited the activation of p38 MAPK and p53 and further blocked apoptosis occurrence through suppressing the TGEV-induced Bcl-2 reduction, Bax redistribution, cytochrome c release and caspase-3 activation. These results suggest that oxidative stress pathway might be a key element in TGEV-induced apoptosis and TGEV pathogenesis.

  8. The sialic acid binding activity of the S protein facilitates infection by porcine transmissible gastroenteritis coronavirus

    Full Text Available Abstract Background Transmissible gastroenteritis virus (TGEV has a sialic acid binding activity that is believed to be important for enteropathogenicity, but that has so far appeared to be dispensable for infection of cultured cells. The aims of this study were to determine the effect of sialic acid binding for the infection of cultured cells under unfavorable conditions, and comparison of TGEV strains and mutants, as well as the avian coronavirus IBV concerning their dependence on the sialic acid binding activity. Methods The infectivity of different viruses was analyzed by a plaque assay after adsorption times of 5, 20, and 60 min. Prior to infection, cultured cells were either treated with neuraminidase to deplete sialic acids from the cell surface, or mock-treated. In a second approach, pre-treatment of the virus with porcine intestinal mucin was performed, followed by the plaque assay after a 5 min adsorption time. A student's t-test was used to verify the significance of the results. Results Desialylation of cells only had a minor effect on the infection by TGEV strain Purdue 46 when an adsorption period of 60 min was allowed for initiation of infection. However, when the adsorption time was reduced to 5 min the infectivity on desialylated cells decreased by more than 60%. A TGEV PUR46 mutant (HAD3 deficient in sialic acid binding showed a 77% lower titer than the parental virus after a 5 min adsorption time. After an adsorption time of 60 min the titer of HAD3 was 58% lower than that of TGEV PUR46. Another TGEV strain, TGEV Miller, and IBV Beaudette showed a reduction in infectivity after neuraminidase treatment of the cultured cells irrespective of the virion adsorption time. Conclusions Our results suggest that the sialic acid binding activity facilitates the infection by TGEV under unfavorable environmental conditions. The dependence on the sialic acid binding activity for an efficient infection differs in the analyzed TGEV strains.

    Intestinal epithelial cells are the targets for transmissible gastroenteritis (TGE) virus (TGEV) infection. It is urgent to develop a novel candidate against TGEV entry. Bacillus subtilis is a probiotic with excellent anti-microorganism properties and one of its secretions, surfactin, has been regarded as a versatile weapon for most plant pathogens, especially for the enveloped virus. We demonstrate for the first time that B. subtilis OKB105 and its surfactin can effectively inhibit one animal coronavirus, TGEV, entering the intestinal porcine epithelial cell line (IPEC-J2). Then, several different experiments were performed to seek the might mechanisms. The plaque assays showed that surfactant could reduce the plaque generation of TGEV in a dose-dependent manner. Meanwhile, after incubation with TGEV for 1.5 h, B. subtilis could attach TGEV particles to their surface so that the number of virus to bind to the host cells was declined. Furthermore, our data showed that the inhibition of B. subtilis was closely related to the competition with TGEV for the viral entry receptors, including epidermal growth factor receptor (EGFR) and aminopeptidase N (APN) protein. In addition, Western blotting and apoptosis analysis indicated that B. subtilis could enhance the resistance of IPEC-J2 cells by up-regulating the expression of toll-like receptor (TLR)-6 and reducing the percentage of apoptotic cells. Taken together, our results suggest that B. subtilis OKB105 and its surfactin can antagonize TGEV entry in vitro and may serve as promising new candidates for TGEV prevention. © 2017 The Author(s).

    Full Text Available The interactions occurring between a virus and a host cell during a viral infection are complex. The purpose of this paper was to analyze altered cellular protein levels in porcine transmissible gastroenteritis coronavirus (TGEV-infected swine testicular (ST cells in order to determine potential virus-host interactions. A proteomic approach using isobaric tags for relative and absolute quantitation (iTRAQ-coupled two-dimensional liquid chromatography-tandem mass spectrometry identification was conducted on the TGEV-infected ST cells. The results showed that the 4-plex iTRAQ-based quantitative approach identified 4,112 proteins, 146 of which showed significant changes in expression 48 h after infection. At 64 h post infection, 219 of these proteins showed significant change, further indicating that a larger number of proteomic changes appear to occur during the later stages of infection. Gene ontology analysis of the altered proteins showed enrichment in multiple biological processes, including cell adhesion, response to stress, generation of precursor metabolites and energy, cell motility, protein complex assembly, growth, developmental maturation, immune system process, extracellular matrix organization, locomotion, cell-cell signaling, neurological system process, and cell junction organization. Changes in the expression levels of transforming growth factor beta 1 (TGF-β1, caspase-8, and heat shock protein 90 alpha (HSP90α were also verified by western blot analysis. To our knowledge, this study is the first time the response profile of ST host cells following TGEV infection has been analyzed using iTRAQ technology, and our description of the late proteomic changes that are occurring after the time of vigorous viral production are novel. Therefore, this study provides a solid foundation for further investigation, and will likely help us to better understand the mechanisms of TGEV infection and pathogenesis.

    Transmissible gastroenteritis (TGE) causes severe diarrhea in suckling piglets, results in enormous economic loss in swine-producing areas of the world. To develop an effective, safe, and convenient vaccine for the prevention of TGE, we have constructed a recombinant Bacillus subtilis strain (B. subtilis CotGSG) displaying the transmissible gastroenteritis virus (TGEV) spike (S) protein and discussed its immune function to intestinal submucosal dendritic cells (DCs). Our results showed that the recombinant B. subtilis had the ability to recruit more DCs to sample B. subtilis CotGSG, migrate to MLNs, and induce immune responses. Immunized piglets with B. subtilis CotGSG could significantly elevate the specific SIgA titers in feces, IgG titers and neutralizing antibodies in serum. Collectively, our results suggested that recombinant B. subtilis CotGSG expressing the TGEV S protein could effectively induce immune responses via DCs, and provided a perspective on potential novel strategy and approach that may be applicable to the development of the next generation of TGEV vaccines.

    2013-07-01

    Full Text Available The spike proteins of a number of coronaviruses are able to bind to sialic acids present on the cell surface. The importance of this sialic acid binding ability during infection is, however, quite different. We compared the spike protein of transmissible gastroenteritis virus (TGEV and the spike protein of infectious bronchitis virus (IBV. Whereas sialic acid is the only receptor determinant known so far for IBV, TGEV requires interaction with its receptor aminopeptidase N to initiate infection of cells. Binding tests with soluble spike proteins carrying an IgG Fc-tag revealed pronounced differences between these two viral proteins. Binding of the IBV spike protein to host cells was in all experiments sialic acid dependent, whereas the soluble TGEV spike showed binding to APN but had no detectable sialic acid binding activity. Our results underline the different ways in which binding to sialoglycoconjugates is mediated by coronavirus spike proteins.

    A modified method of autoradiographic determination of virus antibodies of gastroenteritis of swine was developed. It is based on the actual reaction between antigen bound in cells of the infected cell cultures and antibodies in tested sera, which is visualized by rabbit antibodies labelled with /sup 125/I (/sup 125/I RaSw IgG antibody) to porcine IgG, on a sensitive radiograph and evaluated by darkening at the point of positive immunological reaction. Specificity of the test and mutual comparability and reproducibility of the results were confirmed by examining the known positive and negative sera and by a comparison with the results of the virus-neutralization test. Of the 36 examined porcine blood sera, antibodies were only proved autoradiographically in the samples positive also by virus-neutralization. In experimentally infected pigs, the same dynamics of antibody production was recorded by the two tests. They were, however, demonstrated autoradiographically the eighth day after infection, while by virus neutralization test as late as 14th day. Their level increased gradually till 35th day after infection.

    Transmissible gastroenteritis virus (TGEV) is a coronavirus characterized by diarrhea and high morbidity rates, and the mortality rate is 100% in piglets less than 2 weeks old. Pigs infected with TGEV often suffer secondary infection by other pathogens, which aggravates the severity of diarrhea, but the mechanisms remain unknown. Here, we hypothesized that persistent TGEV infection stimulates the epithelial-mesenchymal transition (EMT), and thus enterotoxigenic Escherichia coli (ETEC) can more easily adhere to generating cells. Intestinal epithelial cells are the primary targets of TGEV and ETEC infections. We found that TGEV can persistently infect porcine intestinal columnar epithelial cells (IPEC-J2) and cause EMT, consistent with multiple changes in key cell characteristics. Infected cells display fibroblast-like shapes; exhibit increases in levels of mesenchymal markers with a corresponding loss of epithelial markers; have enhanced expression levels of interleukin-1β (IL-1β), IL-6, IL-8, transforming growth factor β (TGF-β), and tumor necrosis factor alpha (TNF-α) mRNAs; and demonstrate increases in migratory and invasive behaviors. Additional experiments showed that the activation of the phosphatidylinositol 3-kinase (PI3K)/Akt and extracellular signal-regulated kinase (ERK) signaling pathways via TGF-β is critical for the TGEV-mediated EMT process. Cellular uptake is also modified in cells that have undergone EMT. TGEV-infected cells have higher levels of integrin α5 and fibronectin and exhibit enhanced ETEC K88 adhesion. Reversal of EMT reduces ETEC K88 adhesion and inhibits the expression of integrin α5 and fibronectin. Overall, these results suggest that TGEV infection induces EMT in IPEC-J2 cells, increasing the adhesion of ETEC K88 in the intestine and facilitating dual infection. IMPORTANCE Transmissible gastroenteritis virus (TGEV) causes pig diarrhea and is often followed by secondary infection by other pathogens. In this study, we showed

    In this study, a novel duplex nanoparticle-assisted polymerase chain reaction (nanoPCR) assay was developed to detect porcine epidemic diarrhea virus (PEDV) and porcine transmissible gastroenteritis virus (TGEV). Two pairs of primers were designed based on the conserved region within the N gene of PEDV and TGEV. In a screening of 114 clinical samples from four provinces in China for PEDV and TGEV, 48.2 and 3.5 % of the samples, respectively, tested positive. Under optimized conditions, the duplex nanoPCR assay had a detection limit of 7.6 × 10 1 and 8.5 × 10 1 copies μL -1 for PEDV and TGEV, respectively. The sensitivity of the duplex nanoPCR assay was ten times higher than that of a conventional PCR assay. Moreover, no fragments were amplified when the duplex nanoPCR assay was used to test samples containing other porcine viruses. Our results indicate that the duplex nanoPCR assay described here is useful for the rapid detection of PEDV and TGEV and can be applied in clinical diagnosis.

    Acute gastroenteritis (AGE) is a major cause of illness in the United States, with an estimated 179 million episodes annually. AGE outbreaks propagated through direct person-to-person contact, contaminated environmental surfaces, and unknown modes of transmission were not systematically captured at the national level before 2009 and thus were not well characterized. 2009-2013. The National Outbreak Reporting System (NORS) is a voluntary national reporting system that supports reporting of all waterborne and foodborne disease outbreaks and all AGE outbreaks resulting from transmission by contact with contaminated environmental sources, infected persons or animals, or unknown modes. Local, state, and territorial public health agencies within the 50 U.S. states, the District of Columbia (DC), five U.S. territories, and three Freely Associated States report outbreaks to CDC via NORS using a standard online data entry system. A total of 10,756 AGE outbreaks occurred during 2009-2013, for which the primary mode of transmission occurred through person-to-person contact, environmental contamination, and unknown modes of transmission. NORS received reports from public health agencies in 50 U.S. states, DC, and Puerto Rico. These outbreaks resulted in 356,532 reported illnesses, 5,394 hospitalizations, and 459 deaths. The median outbreak reporting rate for all sites in a given year increased from 2.7 outbreaks per million population in 2009 to 11.8 outbreaks in 2013. The etiology was unknown in 31% (N = 3,326) of outbreaks. Of the 7,430 outbreaks with a suspected or confirmed etiology reported, norovirus was the most common, reported in 6,223 (84%) of these outbreaks. Other reported suspected or confirmed etiologies included Shigella (n = 332) and Salmonella (n = 320). Outbreaks were more frequent during the winter, with 5,716 (53%) outbreaks occurring during December-February, and 70% of the 7,001 outbreaks with a reported setting of exposure occurred in long

    Preferential RNA packaging in coronaviruses involves the recognition of viral genomic RNA, a crucial process for viral particle morphogenesis mediated by RNA-specific sequences, known as packaging signals. An essential packaging signal component of transmissible gastroenteritis coronavirus (TGEV) has been further delimited to the first 598 nucleotides (nt) from the 5' end of its RNA genome, by using recombinant viruses transcribing subgenomic mRNA that included potential packaging signals. The integrity of the entire sequence domain was necessary because deletion of any of the five structural motifs defined within this region abrogated specific packaging of this viral RNA. One of these RNA motifs was the stem-loop SL5, a highly conserved motif in coronaviruses located at nucleotide positions 106 to 136. Partial deletion or point mutations within this motif also abrogated packaging. Using TGEV-derived defective minigenomes replicated in trans by a helper virus, we have shown that TGEV RNA packaging is a replication-independent process. Furthermore, the last 494 nt of the genomic 3' end were not essential for packaging, although this region increased packaging efficiency. TGEV RNA sequences identified as necessary for viral genome packaging were not sufficient to direct packaging of a heterologous sequence derived from the green fluorescent protein gene. These results indicated that TGEV genome packaging is a complex process involving many factors in addition to the identified RNA packaging signal. The identification of well-defined RNA motifs within the TGEV RNA genome that are essential for packaging will be useful for designing packaging-deficient biosafe coronavirus-derived vectors and providing new targets for antiviral therapies.

    We present a family where five members (three males and two females) are carriers of der(4)t(Y;4)(q11.23;p16.3). The adult carriers are phenotypicaly normal and fertile; the boy shows macrocephaly, psychomotor retardation, and atypical autism. The FISH on cultured lymphocytes confirmed that the redundant Yq heterochromatin was attached to the 4p-subtelomeric region maintained on the der(4). Sperm FISH analysis performed in a normospermic der(4) carrier showed a significant distortion of the expected 1:1 ratio of the X- and Y-bearing spermatozoa in favor of the X chromosome and significant lack of Y,der(4)spermatozoa. The overall lack of Y spermatozoa was not balanced even by a relative excess of Y,4 sperm. The analysis of X, Y, 7, 8, 18, and 21 sperm disomy and diploidy did not indicate any interchromosomal effect. The chromosome 4 disomy was significantly increased but still very low to be of considerable reproductive significance. The neurodevelomental phenotype of the boy was probably caused by a gene mutation. The coincidental occurrence of such chromosomal aberration and boy's phenotype might lead to misinterpretation of the causal relationship between these findings. It is necessary to consider the results of chromosomal analysis and clinical records of relatives for provide genetic counseling in such families. Copyright © 2011 Wiley-Liss, Inc.

    Rotavirus is the most common cause of gastroenteritis in children requiring hospitalization. It is a very resistant and contagious virus causing nosocomial gastroenteritis. In France, the vaccine against rotavirus has been available since 2006, but the vaccine is not recommended for infant vaccination. The aim of this retrospective study was to describe nosocomial rotavirus gastroenteritis (NRGE) and to assess its impact on children hospitalized in the General Pediatrics Department of Robert-Debré Hospital (Paris) between 1 January 2009 and 31 December 2013. We analyzed the demographic characteristics of children (age, term birth, underlying diseases) and the severity of the NRGE (oral or intravenous hydration), and assessed whether these children could benefit from vaccination against rotavirus. One hundred thirty-six children presented nosocomial rotavirus infection, with an incidence of 2.5 NRGE per 1000 days of hospitalization. The incidence of NRGE was stable between 2009 and 2013 despite the introduction of specific hygiene measures. The average age of the children was 7 months (range: 0.5-111 months). Most often NRGE occurred in children hospitalized for respiratory diseases (65% of cases) and requiring prolonged hospitalization (median: 18 days). One-third of children were born premature (25%). Hydration was oral in 80 patients (59%), by intravenous infusion in 18 patients (13%), and intraosseous in one patient. Half of the patients were aged less than 5 months and could benefit from the protection afforded by vaccination. NRGE are common. Rotavirus mass vaccination should have a positive impact on the incidence of NRGE by reducing the number of children hospitalized for gastroenteritis, therefore indirectly reducing the number of hospital cross-infections of hospitalized children who are too young to be vaccinated.

    Preferential RNA packaging in coronaviruses involves the recognition of viral genomic RNA, a crucial process for viral particle morphogenesis mediated by RNA-specific sequences, known as packaging signals. An essential packaging signal component of transmissible gastroenteritis coronavirus (TGEV) has been further delimited to the first 598 nucleotides (nt) from the 5′ end of its RNA genome, by using recombinant viruses transcribing subgenomic mRNA that included potential packaging signals. The integrity of the entire sequence domain was necessary because deletion of any of the five structural motifs defined within this region abrogated specific packaging of this viral RNA. One of these RNA motifs was the stem-loop SL5, a highly conserved motif in coronaviruses located at nucleotide positions 106 to 136. Partial deletion or point mutations within this motif also abrogated packaging. Using TGEV-derived defective minigenomes replicated in trans by a helper virus, we have shown that TGEV RNA packaging is a replication-independent process. Furthermore, the last 494 nt of the genomic 3′ end were not essential for packaging, although this region increased packaging efficiency. TGEV RNA sequences identified as necessary for viral genome packaging were not sufficient to direct packaging of a heterologous sequence derived from the green fluorescent protein gene. These results indicated that TGEV genome packaging is a complex process involving many factors in addition to the identified RNA packaging signal. The identification of well-defined RNA motifs within the TGEV RNA genome that are essential for packaging will be useful for designing packaging-deficient biosafe coronavirus-derived vectors and providing new targets for antiviral therapies.

    An association between proton pump inhibitor (PPI) therapy and bacterial gastroenteritis has been suggested as well as contradicted. The aim of this study was to examine the association between the use of PPIs and occurrence of bacterial gastroenteritis in the prospective Rotterdam Study. The Rotterdam Study is a population-based cohort study among 14,926 subjects aged 45 years and older with up to 24 years of follow-up. Analyses were performed with a generalized estimating equations method in participants who handed-in a diagnostic stool sample. Furthermore, a nested case–control analysis was performed using the total cohort as a reference group. A bacterial microorganism was isolated in 125 samples, whereas 1174 samples were culture negative. In the generalized estimating equations analysis, we found that participants with a bacterial gastroenteritis were more likely than controls to be current users of PPIs (adjusted OR 1.94; 95 % CI 1.15–3.25). Different sensitivity analyses did not change this result. A considerably higher effect was observed (adjusted OR 6.14; 95 % CI 3.81–9.91), using the total cohort as a reference in a nested case–control analysis. Current PPI therapy is associated with an increased risk of bacterial gastroenteritis. However, by reducing the risk of selection and information bias in our study design, we demonstrated that the effect is lower than previously assumed.

    Although noroviruses were the first viral agents to be linked to gastrointestinal disease, they were long considered a secondary cause far behind rotaviruses. Development of molecular-based diagnostic techniques has provided clearer insight into the epidemiological impact of noroviruses that are now recognized not only as the leading cause of non-bacterial gastroenteritis outbreaks but also as an important cause of sporadic gastroenteritis in both children and adults. Norovirus infection is generally characterized by mild acute vomiting and diarrhea usually lasting for only a few days, but it can lead to more severe and potentially life-threatening symptoms in high-risk groups such as young children, elderly, and immunodeficient persons. It has been demonstrated that they are present in tropical countries. Molecular epidemiological studies have documented the great genetic diversity of noroviruses with regular emergence of variants. Since no vaccine is available, prevention on norovirus infection depends mainly on strict personal and community hygiene measures.

    Full Text Available Shewanella algae is an emerging bacteria rarely implicated as a human pathogen. Previously reported cases of S. algae have mainly been associated with direct contact with seawater. Here we report the isolation of S. algae as the sole etiological agent from a patient suffering from acute gastroenteritis with bloody diarrhoea. The bacterium was identified by automated identification system and 16S rRNA gene sequence analysis. Our report highlights the importance of looking for the relatively rare aetiological agents in clinical samples that does not yield common pathogens. It also underscores the usefulness of automated systems in identification of rare pathogens.

    Full Text Available In June 2006, an outbreak alert regarding cases of acute gastroenteritis in a region in North Eastern Greece (population 100,882 inhabitants, triggered investigations to guide control measures. The outbreak started the first days of June, and peaked in July. A descriptive epidemiological study, a virological characterization of the viral agent identified from cases as well as a phylogenetic analysis was performed. From June 5 to September 3, 2006 (weeks 23–44, 1,640 cases of gastroenteritis (45.2% male and 54.8% female, aged 3 months to 89 years were reported. The overall attack rate for the period was 16.3 cases/1,000 inhabitants. About 57% of cases observed were under the age of 15 years. Αnalysis of faecal samples identified Norovirus GII strains. Fifteen different Norovirus GII strains were recorded, presenting a homology of 94.8% (86–97% to GII strains obtained from GenBank. The long duration of the outbreak suggests an important role of person-to-person transmission, while the emergence of the outbreak was possibly due to contaminated potable water, although no viruses were detected in any tested water samples. This outbreak underscores the need for a national surveillance system for acute non-bacterial gastroenteritis outbreaks.

    The idea that human boca virus (HBoV) infection possibly plays a role in gastroenteritis has been suggested because of the frequent manifestation of gastrointestinal symptoms. The purpose of this study was to investigate the role of HBoV In children with gastroenteritis. We studied the etiologic agents in 100 fecal samples in children suffered from acute gastroenteritis. Bacterial etiological agents were dtected by conventional bacteriological culture, and viral etiologic agents were detected by rotavirus latex agglutination and conventional PCR for HBoV and enteric adenovirus. Enteropathogenic E-Coli (EPEC) was detected in 4% of cases. Rotatavirus, enteric adenovirus and co infection between rotavirus and adenovirus were detected in 14%, 6% and 2% respectively. Human boca virus was detected in 1% of cases without associated respiratory symptoms or co infection with other pathogen which suggests its role in children gastroenteritis

It causes significant mortality in developing countries and significant economic burden to developed countries. Viruses are ­responsible for approximately 70% of episodes of acute gastroenteritis in children and rotavirus is one of the best studied of these viruses. Oral rehydration therapy is as effective as i­ntravenous therapy in treating mild to moderate dehydration in acute gastroenteritis and is strongly r­ecommended as the first line therapy. However, the oral rehydration solution is described as an underused simple solution. Vomiting is one of the main reasons to explain the underuse of oral rehydration therapy. Antiemetics are not routinely recommended in treating acute gastroenteritis, though they are still commonly prescribed. Ondansetron is one of the best studied antiemetics and its role in enhancing the compliance of oral rehydration therapy and decreasing the rate of hospitalization has been proved recently. The guidelines regarding the recommendation on antiemetics have been changed according to the evidence of these recent studies.Keywords: gastroenteritis, vomiting, antiemetic, ondansetron, rotavirus, oral rehydration therapy, intravenous therapy, guideline

    This report presents two cases with eosinophilic gastroenteritis in detail. The radiographic and pathologic features of eosinophilic gastroenteritis are summarized with emphasis on the differential diagnostic features. Radiographic eosinophilic gastritis should be differentiated from gastric carcinoma and lymphoma, and eosinophilic enteritis from intestinal tuberculosis and intussusception of the small bowel in Korea where these entities are prevent. Eosinophilic gastroenteritis is pathologically characterized by diffuse infiltration of the submucosa and muscle coats with eosinophilic in conjunction with hypertrophy of individual muscle fibers. This leads to thickening of the gastrointestinal wall resulting in narrowing and obstruction of the lumen. Eosinophilic venulitis is another characteristic feature which is helpful for differentiation this entity from a parasitic infection.

    2000-11-01

    Aim: The aim of the study was the determination of the radiation exposure to the patient caused by single-photon transmission measurement for 3D whole-body PET. Material and method: Single-photon-transmission measurement is performed using two Cs-137 pointsources (E{gamma}=662 keV, A=2*614 MBq) on a 3D PET scanner (ECAT ART). During a simulation of a whole body transmission scan (axial length: 75 cm, 6 contigous bed positions) dose measurements with thermoluminescent dosimeters were carried out using a thorax and an abdomen phantom. Following the guidelines of the ICRU report No. 60 an estimation of the effective dose caused by a single-photon transmission measurement was calculated. Results: For a total acquisition time of 360 min (6 beds with an acquisition time of 60 min per bed) the absorbed doses amounted to: Surface (xyphoid) 189 {mu}Gy, heart 196 {mu}Gy, lungs 234 {mu}Gy, vertebra 240 {mu}Gy, liver 204 {mu}Gy, gonads 205 {mu}Gy, thyroid 249 {mu}Gy and bladder 185 {mu}Gy resulting in a conversion factor of 1.7*10{sup -4} mSv/(h*MBq). The estimation of the effective dose for a patient's transmission (acquisition time of 3.2 min per bed) yields a value of 11 {mu}Sv. An estimation of the ratio of the conversion factors for transmission measurements in single-photon- and in coincidence mode (two Ge-68/Ga-68 rod sources of 40 MBq each), respectively, resulted in a value of 0.18. The comparison of the effective doses caused by single-photon transmission and by emission measurement (injection of 250 MBq of FDG) yields a ratio of 2.3*10{sup -3}. Conclusion: The radiation exposure of the patient caused by the transmission measurement for 3D whole-body-PET can be neglected. In comparison with the coincidence-transmission using uncollimated line sources of low activity the radiation exposure is still reduced using single photon transmission with collimated point sources of high activity.

    2017-02-01

    Full Text Available Since they were identified in 1975, human astroviruses have been considered one of the most important agents of viral acute gastroenteritis in children. However, highly divergent astroviruses infecting humans have been recently discovered and associated with extra-intestinal infections. The report of cases of fatal meningitis and encephalitis, especially in immunocompromised individuals, has broadened their disease spectrum. Although zoonotic transmission among animal and human astroviruses has not been clearly recognized, the genetic similarity between some human and animal viruses makes it likely to occur. This review provides an update on the epidemiology of both classic and novel human astroviruses, and a comprehensive view on confirmed or potential association between astrovirus and human disease.

    When oral rehydration is not feasible, enteral rehydration via the nasogastric route has been the ESPGHAN recommended method of rehydration since 2008, rather than intravenous rehydration (IVR), for children with acute gastroenteritis. However, these recommendations are rarely followed in France. Since 2011, in case of failure of oral rehydration, enteral rehydration has been used as a first-line therapy in the Children's Emergency Department at the Grenoble-Alpes University Hospital. The aims of the study were to compare the length of the hospital stay, the duration of initial rehydration, and the incidence of complications and failure with the use of enteral nasogastric versus intravenous rehydration. This study compared two cohorts of children (rehydration via the oral route. The first group (winter 2010-2011) was managed according to the previous protocol (intravenous rehydration). The second group (winter 2011-2012) was managed according the new protocol (nasogastric tube rehydration [NGR]). The rest of the gastroenteritis management was identical in both groups. A total of 132 children were included, 65 were treated with nasogastric tube rehydration (NGR) and 67 with intravenous rehydration. There was a significant reduction in the duration of hospitalization in the post-emergency unit in the NGR group: 23.6h vs 40.1h (Prehydration was also significantly reduced (10.5h vs 22.0h). There was no significant difference regarding serious adverse events. However, the NGR group presented more mild adverse events (22 vs 7, Prehydration reduces the duration of rehydration and the length of the hospital stay without increasing the incidence of serious adverse events for dehydrated children hospitalized for acute gastroenteritis.

    Full Text Available The work aimed at studying a series of diagnostic aspects and determination of the possible treatment of children with acute gastroenetrites according to the protocol based on international recommendations and standards. The study involved 130 children, of whom in 71 patients the presence of rotavirus antigen in coprofilters was checked via latex particle agglutination method. In 85% rotavirus infection was confirmed. It was shown that the majority of cases fall on November to may. Infant and early children are the most susceptible to rotavirus gastroenteritis. The analysis of therapy results showed that antibioticsfree treatment of watery diarrhea patients worked well, and prescription of antibacterial therapy for the concomitant bacterial infection does not influence the time of gastroenteritis reduction. The results of dehydration therapy show that oral rehydration is not always effective for the 2nd stage dehydration, especially with late treatment. However, the time of recovery (diarrhea reduction does not depend on the type of rehydration or symptomatic therapy. A diagnostic algorithm that helps use the minimum diagnostic methods in stationary conditions and at the same time provides the optimum scope of therapeutic intervention was worked out.Key words: rotavirus infection, children, rehydration, antibacterial therapy.

    The series development of hybrid systems in combination with the new ZF 8-speed automatic transmissions contains also for the testing several aspects of challenge the complex overall system with additional loads, components and functions requires new definitions of testing volumes and load collectives with an ideal integration of testing expertise of all parties involved. This paper describes how, already in an early development stage of the fully hybridised 8-speed transmission system, specific load collectives have been developed with the aid of simulation. So the ''hybrid-effect'' as an additional load and its influence on the durability compared to non hybridised applications could be identified. Also it is shown how testing collectives have been adapted in practice to the hybrid specific needs to the point of a specific assembly of a test bench. The ZF testing concept for hybridised automatic transmissions has the ability of an early and efficient verification of the production readiness also securing highest possible series production quality for prospective hybrid projects.

    In January, 1980, six out of 13 persons (46%) attending a party in a small northwest Florida town near the Gulf of Mexico became ill with Norwalk virus gastroenteritis after eating raw oysters. Symptoms experienced by the ill persons were principally nausea (100%), vomiting (83%) and diarrhea (50%) and were of brief duration. The symptom complex and epidemiology of Norwalk virus infection closely resemble the gastrointestinal illness commonly referred to as the 24-hour intestinal flu or "stomach flu." Norwalk virus infection was identified in this outbreak by application of a recently developed sensitive and specific serologic radioimmunoassay. Oysters from the incriminated batch had fecal coliform levels above recommended standards; however, recent studies of oyster-harvesting waters have shown only a weak correlation between fecal coliforms and the presence of enteric viruses. Further studies are needed to determine whether modifications of monitoring modalities for oyster-harvesting waters are needed.

    Distributed energy resources (DER) are quickly making their way to industry primarily as backup generation. They are effective at starting and then producing full-load power within a few seconds. The distribution system is aging and transmission system development has not kept up with the growth in load and generation. The nation's transmission system is stressed with heavy power flows over long distances, and many areas are experiencing problems in providing the power quality needed to satisfy customers. Thus, a new market for DER is beginning to emerge. DER can alleviate the burden on the distribution system by providing ancillary services while providing a cost adjustment for the DER owner. This report describes 10 types of ancillary services that distributed generation (DG) can provide to the distribution system. Of these 10 services the feasibility, control strategy, effectiveness, and cost benefits are all analyzed as in the context of a future utility-power market. In this market, services will be provided at a local level that will benefit the customer, the distribution utility, and the transmission company.

    Although most cases of acute gastroenteritis require minimal medical intervention, severe dehydration and hypoglycemia may develop in cases of prolonged vomiting and diarrhea. The mainstay of treatment for mild-to-moderately dehydrated patients with acute gastroenteritis should be oral rehydration solution. Antiemetics allow for improved tolerance of oral rehydration solution, and, when used appropriately, can decrease the need for intravenous fluids and hospitalization. This issue reviews the common etiologies of acute gastroenteritis, discusses more-severe conditions that should be considered in the differential diagnosis, and provides evidence-based recommendations for management of acute gastroenteritis in patients with mild-to-moderate dehydration, severe dehydration, and hypoglycemia.

    Full Text Available Introduction : Rotavirus gastroenteritis is an important public health problem all over the world, causing a notable economic burden in both developing and developed countries. Aim: To explore the relationship between blood group typing, rotavirus gastroenteritis, and its severity in Egyptian children. Material and methods: A cross sectional case control study was conducted on 231 cases of acute gastroenteritis attending the outpatient clinic of Al-Zahraa University Hospital. Full history taking, clinical examination, and clinical data collection were done. Blood samples were collected for an ABO grouping. Stool samples were tested for viral gastroenteritis agents. Results : Rota positive cases of GE were significantly more prevalent among cases with blood group A (p < 0.05 and significantly less among cases with blood group B (p < 0.05. The rate of hospitalisation was highly significantly greater among cases with group A (p < 0.005, and significantly lower among cases with group AB and O (p < 0.05. As regards the degree of dehydration, moderate and severe cases were highly significant in groups A and O (p < 0.005. Rota-positive gastroenteritis showed significant positive correlations with indicators of severity such as hospitalisation, degree of dehydration, and duration of fever (p < 0.005. Conclusions : Blood group A is highly associated with paediatric rotavirus gastroenteritis. This could highlight an important risk factor, which could play a significant role for the pathogenesis of rotavirus gastroenteritis and severity as well. Furthermore, more intervention care could be needed for blood group A paediatric patients, if gastroenteritis especially rotavirus affect this group to avoid comorbidities.

    The primary objective of this work was the first experimental realization of parallel RF transmission for accelerating spatially selective excitation in magnetic resonance imaging. Furthermore, basic aspects regarding the performance of this technique were investigated, potential risks regarding the specific absorption rate (SAR) were considered and feasibility studies under application-oriented conditions as first steps towards a practical utilisation of this technique were undertaken. At first, based on the RF electronics platform of the Bruker Avance MRI systems, the technical foundations were laid to perform simultaneous transmission of individual RF waveforms on different RF channels. Another essential requirement for the realization of Parallel Excitation (PEX) was the design and construction of suitable RF transmit arrays with elements driven by separate transmit channels. In order to image the PEX results two imaging methods were implemented based on a spin-echo and a gradient-echo sequence, in which a parallel spatially selective pulse was included as an excitation pulse. In the course of this work PEX experiments were successfully performed on three different MRI systems, a 4.7 T and a 9.4 T animal system and a 3 T human scanner, using 5 different RF coil setups in total. In the last part of this work investigations regarding possible applications of Parallel Excitation were performed. A first study comprised experiments of slice-selective B1 inhomogeneity correction by using 3D-selective Parallel Excitation. The investigations were performed in a phantom as well as in a rat fixed in paraformaldehyde solution. In conjunction with these experiments a novel method of calculating RF pulses for spatially selective excitation based on a so-called Direct Calibration approach was developed, which is particularly suitable for this type of experiments. In the context of these experiments it was demonstrated how to combine the advantages of parallel transmission

    Gastroenteric tube feeding plays a major role in the management of patients with poor voluntary intake, chronic neurological or mechanical dysphagia or gut dysfunction, and patients who are critically ill. However, despite the benefits and widespread use of enteral tube feeding, some patients experience complications. This review aims to discuss and compare current knowledge regarding the clinical application of enteral tube feeding, together with associated complications and special aspects. We conducted an extensive literature search on PubMed, Embase and Medline using index terms relating to enteral access, enteral feeding/nutrition, tube feeding, percutaneous endoscopic gastrostomy/jejunostomy, endoscopic nasoenteric tube, nasogastric tube, and refeeding syndrome. The literature showed common routes of enteral access to include nasoenteral tube, gastrostomy and jejunostomy, while complications fall into four major categories: mechanical, e.g., tube blockage or removal; gastrointestinal, e.g., diarrhea; infectious e.g., aspiration pneumonia, tube site infection; and metabolic, e.g., refeeding syndrome, hyperglycemia. Although the type and frequency of complications arising from tube feeding vary considerably according to the chosen access route, gastrointestinal complications are without doubt the most common. Complications associated with enteral tube feeding can be reduced by careful observance of guidelines, including those related to food composition, administration rate, portion size, food temperature and patient supervision.

    The German transmission system operators are obliged to make and publish forecasts on the development of the nationwide EEG apportionment on a calendar year basis. An important part of this study is a forecast of the electricity consumption to final consumers. In addition the electricity consumption of the self-suppliers,the final consumption is to be investigated according to the privilege categories for which the EEG apportionment has to be paid in a reduced amount. The final consumption amounted to about 463 TWh in 2014 and falls steadily to about 446 TWh by 2020. In 2016 the final consumption is about 460 TWh. The decline in final consumption is slightly more pronounced than in the case of net electricity demand, which is attributable to the rising self-supply. The net electricity demand in 2014 was about 513 TWh, which is about 15 TWh lower than in 2013. The decline is due in part to an increase in energy efficiency in electricity-based applications and on the other hand to mild weather. In the reference scenario, net electricity demand will decline from about 512 TWh in 2016 to about 506 TWh in 2020. The net electricity demand in the sectors of households and industry is decreasing, but increasing in the area of the TCS sector and the transport sector. In the course of the renewal of the EEG in 2014, regulations for the self-supply of electricity have been introduced for the first time, according to which operators of new plants larger than 10 kW and an annual self-sufficiency of more than 10 MWh have to pay a proportionate EEG apportionment, which increases in the subsequent years. While this regulation in the TCS sector leads to a stagnation of self-supply, the industrial sector is expected to continue replacement construction. An increase in the PV self-supply volume is expected for private households. Self-supply will increase from around 52 TWh in 2016 to around 53 TWh in 2020. The development of the future non-privileged final consumption, which is

Salesi", Ancona, Italy Abstract: Acute gastroenteritis, characterized by the onset of diarrhea with or without vomiting, continues to be a major cause of morbidity and mortality in children in mostly resource-constrained nations. Although generally a mild and self-limiting disease, gastroenteritis is one of the most common causes of hospitalization and is associated with a substantial disease burden. Worldwide, up to 40% of children aged less than 5 years with diarrhea are hospitalized with rotavirus. Also, some microorganisms have been found predominantly in resource-constrained nations, including Shigella spp, Vibrio cholerae, and the protozoan infections. Prevention remains essential, and the rotavirus vaccines have demonstrated good safety and efficacy profiles in large clinical trials. Because dehydration is the major complication associated with gastroenteritis, appropriate fluid management (oral or intravenous is an effective and safe strategy for rehydration. Continuation of breastfeeding is strongly recommended. New treatments such as antiemetics (ondansetron, some antidiarrheal agents (racecadotril, and chemotherapeutic agents are often proposed, but not yet universally recommended. Probiotics, also known as “food supplement,” seem to improve intestinal microbial balance, reducing the duration and the severity of acute infectious diarrhea. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition and the European Society of Paediatric Infectious Diseases guidelines make a stronger recommendation for the use of probiotics for the management of acute gastroenteritis, particularly those with documented efficacy such as Lactobacillus rhamnosus GG, Lactobacillus reuteri, and Saccharomyces boulardii.

    It is described an acute gastroenteritis outbreak of probable hydric transmission in Ontinyent (Valencia). It was declared on the 31st of January, 1992 and affected 3541 people according to the declaration done by the sanitary services who attended the patients. The clinical situation was characterized by the presence of profuse and watery diarrhoea, nausea, vomiting, abdominal pain and fever or febricula. A preliminary study of the cases has been done, the information being treated with the classical method of descriptive epidemiology and a later study of the transversal observation type by means of a telephone inquiry. The results show that this outbreak affected approximately to a 30% of the population, and show the relation between consumption of water from the municipal water system and the outbreak, as well as the existence of a control population not affected for receiving a different water supply. Once rejected the bacterial origin for the results of the copro-cultivation done the analysis of the clinical and epidemiological characteristics of the outbreak, show a total agreement with the criteria described by Kaplan to characterize acute gastroenteritis outbreaks because of Norwalk-like virus.

    An outbreak of gastroenteritis affected 453 attendees (attack rate 28·5%) of six separate events held at a hotel in Singapore. Active case detection, case-control studies, hygiene inspections and microbial analysis of food, environmental and stool samples were conducted to determine the aetiology of the outbreak and the modes of transmission. The only commonality was the food, crockery and cutlery provided and/or handled by the hotel's Chinese banquet kitchen. Stool specimens from 34 cases and 15 food handlers were positive for norovirus genogroup II. The putative index case was one of eight norovirus-positive food handlers who had worked while they were symptomatic. Several food samples and remnants tested positive for Escherichia coli or high faecal coliforms, aerobic plate counts and/or total coliforms, indicating poor food hygiene. This large common-source outbreak of norovirus gastroenteritis was caused by the consumption of contaminated food and/or contact with contaminated crockery or cutlery provided or handled by the hotel's Chinese banquet kitchen.

    Hajj is the annual gathering of Islam practitioners in Mecca, Saudi Arabia. During the event, gastrointestinal infections are usually experienced and outbreaks have always been a concern; nevertheless, a deep and integrative study of the etiological agents has never been carried out. Here, I describe for the first time the epidemiology of pathogenic enteric viruses during Hajj 2011, 2012 and 2013. The focus of this study was the common enteric viruses Astrovirus, Norovirus, Rotavirus and Adenovirus. An enzyme Immunoassay established their presence in 14.9%, 15.0% and 6.6% of the reported cases of acute diarrhea for 2011, 2012 and 2013, respectively. For the three years of study, Astrovirus accounted for the majority of the viral infections. To our knowledge, this is the first time an epidemiological study depicts Astrovirus as the main viral agent of gastroenteritis in a mass gathering event. Hajj is rich in strains of Astrovirus, Norovirus and Rotavirus. A first screening by RT-PCR resulted in ten different genotypes. Strains HAstV 2, HAstV 1 and HAstV 5 were identified for Astrovirus. GI.6, GII.3, GII.4 and GII.1 were described for Norovirus and G1P[8], G4P[8] and G3P[8] were found for Rotavirus. The majority of the Astrovirus isolates could not be genotyped suggesting the presence of a new variant(s). Cases like this encourage the use of metagenomics (and nextgeneration sequencing) as a state-of-the-art technology in clinical diagnosis. A sample containing Adenovirus particles is being used to standardize a process for detection directly from stool samples and results will be obtained in the near future. The overall findings of the present study support the concept of Hajj as a unique mass gathering event that potentiates the transmission of infectious diseases. The finding of Norovirus GII.4 Sydney, a variant originated from Australia, suggests that Hajj is a receptor of infectious diseases worldwide. This work is part of the Hajj project, a collaborative

    Full Text Available Abstract Background Rotavirus is the leading cause of severe diarrhea in young children and causes substantial morbidity and mortality. Although the clinical aspects have been well described, little information is available regarding the emotional, social, and economic impact of rotavirus gastroenteritis on the family of a sick child. The objectives of this study were to: 1 assess the family impact of rotavirus gastroenteritis through qualitative interviews with parents; 2 compare the clinical severity of rotavirus-positive and negative gastroenteritis; 3 test a questionnaire asking parents to rank the importance of various factors associated with a case of rotavirus gastroenteritis. Methods The study enrolled parents and children (2–36 months of age brought to one of the study sites (outpatient clinic or ER if the child experienced ≥ 3 watery or looser-than normal stools and/or forceful vomiting within any 24-hour period within the prior 3 days. The clinical severity of each child's illness was rated using a clinical scoring system and stool samples were tested for rotavirus antigen. Parents of rotavirus-positive children were invited to participate in focus group or individual interviews and subsequently completed a questionnaire regarding the impact of their child's illness. Results Of 62 enrolled children, 43 stool samples were collected and 63% tested positive for rotavirus. Illness was more severe in children with rotavirus-positive compared to rotavirus-negative gastroenteritis (92% vs. 37.5% rated as moderate/severe. Seventeen parents of rotavirus-positive children participated in the interviews and completed the written questionnaire. Parents were frightened by the severity of vomiting and diarrhea associated with rotavirus gastroenteritis, and noted that family life was impacted in several ways including loss of sleep, missed work, and an inability to complete normal household tasks. They expressed frustration at the lack of a

    Power networks have to withstand a variety of disturbances that affect system frequency, and the problem is compounded with the increasing integration of intermittent renewable generation. Following a large-signal generation or load disturbance, system frequency is arrested leveraging primary frequency control provided by governor action in synchronous generators. In this work, we propose a framework for distributed energy resources (DERs) deployed in distribution networks to provide (supplemental) primary frequency response. Particularly, we demonstrate how power-frequency droop slopes for individual DERs can be designed so that the distribution feeder presents a guaranteed frequency-regulation characteristic at the feeder head. Furthermore, the droop slopes are engineered such that injections of individual DERs conform to a well-defined fairness objective that does not penalize them for their location on the distribution feeder. Time-domain simulations for an illustrative network composed of a combined transmission network and distribution network with frequency-responsive DERs are provided to validate the approach.

    Full Text Available Introduction: This paper describes the epidemiological, microbiological and environmental investigations conducted during an outbreak of Salmonella gastroenteritis in Singapore.Methods: A case-control study was undertaken to identify the vehicle of transmission. Microbiological testing was performed on faecal, food and environmental samples. Isolates of Salmonella were further characterized by phage typing and ribotyping.Results: There were 216 gastroenteritis cases reported from 20 November to 4 December 2007. The causative agent was identified as Salmonella enterica subspecies enterica serotype Enteritidis for 14 out of 20 cases tested. The vehicle of transmission was traced to cream cakes produced by a bakery and sold at its retail outlets (P < 0.001, OR = 143.00, 95% Cl = 27.23–759.10. More than two-thirds of the 40 Salmonella strains isolated from hospitalized cases, food samples and asymptomatic food handlers were of phage type 1; the others reacted but did not conform to any phage type. The phage types correlated well with their unique antibiograms. The ribotype patterns of 22 selected isolates tested were highly similar, indicating genetic relatedness. The dendrogram of the strains from the outbreak showed distinct clustering and correlation compared to the non-outbreak strains, confirming a common source of infection.Discussion: The cream cakes were likely contaminated by one of the ingredients used in the icing. Cross-contamination down the production line and subsequent storage of cakes at ambient temperatures for a prolonged period before consumption could have resulted in the outbreak.

    Ein grundlegendes Verständnis der Pathogenese der Endometriose ist eine zwingende Voraussetzung zur Etablierung neuer und wirksamer Therapieoptionen. Dabei erscheint die Endometriose als heterogene Gruppe von Krankheitsformen, die sich unterschiedlich manifestieren. Dies erklärt, weshalb die genaue Pathogenese der Endometriose bis heute ein nicht abschliessend erforschtes Gebiet bleibt.

    Full Text Available Communication in foreign language teaching is gaining more importance in today’s world. Language students find that learning the vocabulary and grammatical structures of a particular language is not enough to gain proficiency in the language. The close relationship between language and culture reveals the fact that it is impossible to master a language without learning its culture. Therefore, the course books used for teaching a foreign language must improve students’ communication skills by raising their cultural awareness. In this study, culture transfer through course books is analyzed and evaluated within the context of teaching Turkish to foreigners. The Yeni Hitit Yabancılar için Türkçe series, the course books used in the Turkish Studies Department at Jagiellonian University, are evaluated according to the following cultural transfer criteria: a subject area, (b type of text and (c visuality. The evaluation of the Yeni Hitit Yabancılar için Türkçe course book series from the perspective of cultural transmission has revealed that they contain elements that present Turkish culture to students with its different aspects and succeed in transmitting the Turkish culture to students for whom they are intended. Course books that promote communicative and intercultural competence should be chosen to teach Turkish as a foreign language at Polish universities. Günümüzde yabancı dil öğretiminde iletişimin önemi gittikçe artmaktadır. Dil öğrenenler için sadece o dilin kelime ve dilbilgisi yapılarını öğrenmek dil yeterliliği açısından yeterli değildir. Dil ve kültür arasındaki yakın ilişki, bir dile o dilin kültürünü öğrenmeden hâkim olunamayacağı gerçeğini ortaya koymaktadır. Bundan dolayı, yabancı dil öğretimi için kullanılan ders kitapları da kültürel farkındalığı artırarak iletişim becerilerini geliştirmesi beklenmektedir.

  19. Der II. Hauptsatz der Wärmelehre

    Heintze, Joachim

    Wir haben in (4.44) den II. Hauptsatz als empirische Tatsache folgendermaßen formuliert: (i) Wärmeenergie geht von selbst nur von einem wärmeren Körper auf einen kälteren über, niemals in der umgekehrten Richtung. Nun werden wir beweisen, dass sich aus diesem Prinzip folgende äquivalente Formulierungen für den II. Hauptsatz ableiten lassen: (ii) Es ist unmöglich, ein Perpetuum mobile zweiter Art zu bauen, d. h. eine Maschine, die fortlaufend Wärmeenergie vollständig in mechanische Arbeit umsetzen kann. Eine Wärmekraftmaschine, die einen Kreisprozess mit der höchsten Temperatur Tw und der niedrigsten Temperatur Tk durchläuft, hat höchstens den Carnotschen Wirkungsgrad c = (Tw - Tk)/Tw. Wenn in der Maschine nur reversible Prozesse ablaufen, die gesamte Wärmezufuhr bei der Temperatur Tw erfolgt und ausschließlich bei der Temperatur Tw gekühlt wird, ist ihr Wirkungsgrad = C. Es gibt keine Wärmekraftmaschine, die eine bessere Ausnutzung der Wärmeenergie ermöglicht. (iv) In jedem thermodynamischen System existiert die Zustandsgröße Entropie, definiert durch ihr Differential dS = (dQrev)/T . Entropie kann erzeugt, aber nicht vernichtet werden. Bei Zustandsänderungen, die in einem abgeschlossenen System ablaufen, nimmt die Entropie entweder zu (irreversible Prozesse), oder sie bleibt konstant (reversible Prozesse). Im Anschluss an (iii) werden wir zur Definition der thermodynamischen Temperatur und bei der Diskussion von (iv) zu einem tieferen Verständnis der Entropie gelangen. Es zeigt sich, dass die Entropie das eigentliche Bindeglied zwischen Mechanik und Wärmelehre darstellt. Am Ende des Kapitels werden wir einige Anwendungen des II. Hauptsatzes betrachten.

    In children, the most significant cause of rhabdomyolysis or muscle breakdown is viral infection. However, there are no reports that norovirus, a gastroenteric virus that commonly infects children, specifically causes rhabdomyolysis. Here, we report the first pediatric case of norovirus-associated rhabdomyolysis. The patient, a 2-year-old boy with fever, diarrhea, and vomiting, was referred to our hospital with dysstasia and transaminitis. He was diagnosed with rhabdomyolysis. Additionally, norovirus genogroup GII was detected from stool samples by real-time quantitative reverse transcription Polymerase Chain Reaction, and thereafter, the norovirus GII.4 variant was identified. However, the association between rhabdomyolysis and the isolated norovirus variant was not clarified. After treatment the patient recovered without renal failure or disseminated intravascular coagulation. Rhabdomyolysis is a disease for which there is a need for early detection and treatment. If abnormal posture or muscle weakness is observed during the course of gastroenteritis, blood and urinary tests should be performed to rule out rhabdomyolysis.

    Full Text Available Eosinophilic Gastroenteritis is a rare disease characterized by infiltration of the gastrointestinal tract by an increased number of eosinophils as compared to the normal. The anatomic location and intensity of the infiltrate decides the varied clinical symptomatology with which these patients present. The present report deals with four cases, all presenting with clinical signs of intestinal obstruction A laparotomy performed revealed a stricture in the first case, superficial ulcers and adhesions in the second case, an ileocaecal mass in the third case and volvulus formation in the fourth case. Eosinophilic gastroenteritis was confirmed on histopathology in all the four cases. All the four patients experienced relief of symptoms after resection. It is essential to diagnose the disease to differentiate it from other conditions presenting as intestinal obstruction. The cases are presented because of the rarity of occurrence and presentation. Relevant literature has been reviewed.

    Eosinophilic gastroenteritis is an uncommon condition characterized by focal or diffuse infiltration of eosinophils in the gastrointestinal tract in the absence of secondary causes. The pathogenesis of this condition is not well understood and its clinical presentation depends on the segment and layer of the gastrointestinal tract affected. The definition of eosinophilic gastroenteritis may be difficult, as the normal ranges of eosinophil numbers in normal and abnormal gastric and intestinal mucosa are not standardized. We present the case of a 59-year-old male who came to the hospital with hypovolemic shock and lethargy secondary to severe diarrhea. Laboratory analysis was significant for peripheral eosinophilia, and pathology from both the duodenum and colon showed marked eosinophilic infiltration.

    Full Text Available High prevalence of acute enteric infections in children, the majority of which affects infants, determines the necessity of development of modern recommendation on diagnostics and treatment of such conditions. The authors show data on etiology of enteric infections and results of various Russian and international research on efficacy of treatment of acute gastroenteritis, including information about sorbents, probiotics, antiemetic agents and antibacterial drugs usage. Recommendations on treatment of acute gastroenteritis are based on the modern protocol of the European Society of Pediatric Gastroenterologists, Hepatologists and Nutritionists (ESPGHAN, which was published in 2008. According to these recommendations, oral rehydration is one of the main components of treatment, decreasing children’s mortality rates. However due to the absence of the effect of this measure on the intestinal peristalsis, duration of the diarrhea and concomitant symptoms (abdominal pain and distension, additional therapy is necessary. In Russia combinations of enterosorbents and probiotics are used in order to relieve such conditions.

    Full Text Available According to the statistics of the recent 5 years, the share of rotavirus gastroenterites is 44-47% of all acute intestinal infections in children under 5 years of age in the Russian Federation. Up to 5% of mortality rate in children under 5 years of age is connected with rotavirus gastroenteritis. Rotavirus gastroenteritis takes an especially severe course in children of 6-24 months of age. The only reliable method of preventing this infection is vaccination. The authors present information on the rotavirus strains dominant in Russia and abroad, efficacy and safety of immunization with a pentavalent vaccine and the recommended schemes of its administration. This vaccine is registered in the Russian Federation; it is to be first used in the nearest future.

    An outbreak of gastroenteritis in New York City's largest jail involved 145 cases over a two-month period. The outbreak was unusual in that two Salmonella strains (serogroups B and D) were involved. Management of the outbreak involved screening kitchen workers by culture of stool samples, and education regarding personal hygiene. Obstacles to investigation and management of the outbreak arose out of the special nature of the jail environment; these included jurisdictional problems and high turnover of the inmate population.

    Full Text Available Abstract Background The highest incidence of rotavirus gastroenteritis has generally been reported in children 6-24 months of age. Young infants are thought to be partially protected by maternal antibodies acquired transplacentally or via breast milk. The purpose of our study was to assess the age distribution of children with confirmed community-acquired rotavirus gastroenteritis presenting to an urban referral hospital. Methods Children presenting to The Children's Hospital of Philadelphia with acute gastroenteritis have been monitored for the presence of rotavirus antigen in the stool by ELISA (followed by genotyping if ELISA-positive since the 1994-95 epidemic season. Results Over the last 12 rotavirus seasons prior to the introduction of the pentavalent rotavirus vaccine in 2006, stool specimens from 1646 patients tested positive for community-acquired rotavirus infection. Gender or age was not recorded in 6 and 5 cases, respectively. Overall, 58% of the cases occurred in boys. G1 was the predominant VP7 serotype, accounting for 72% of cases. The median (IQR age was 11 (5-21 months. A total of 790 (48% cases occurred in children outside the commonly quoted peak age range, with 27% in infants 24 months of age. A total of 220 (13% cases occurred during the first 3 months of life, and the highest number of episodes per month of age [97 (6%] was observed during the second month of life. Conclusions The incidence of community-acquired rotavirus gastroenteritis monitored over 12 seasons in the prevaccine era at a major university hospital was nearly constant for each month of age during the first year of life, revealing an unexpectedly high incidence of symptomatic rotavirus disease in infants

    Introduction. It is estimated up to 6 % of prosthetic vascular grafts become infected. Staphylococcus aureus is predominant in early infection and coagulase-negative staphylococci are predominant in late infections. Enterobacteriaceae cause 14-40 % of prosthetic vascular graft infections. This is, to our knowledge the first reported case of Salmonella gastroenteritis causing chronic prosthetic vascular graft infection (PVGI). Case presentation. A 57 years old lady presented with signs and symptoms of prosthetic vascular graft infection. Three years earlier, she had undergone a prosthetic axillo-femoral bypass graft for critical limb ischaemia. The infected prosthetic vascular graft was removed and Salmonella Typhimurium was isolated on culture. In the intervening period, Salmonella Typhimurium was isolated from a faecal specimen, collected during an episode of acute gastroenteritis. Whole-genome sequencing (WGS) showed that the respective Salmonella Typhimurium isolates differed by only a single nucleotide polymorphism (SNP). Salmonella Typhimurium was not isolated on culture of a faecal specimen collected five days following cessation of antimicrobial therapy. Six months after removal of the prosthetic graft, the patient remains under follow-up for her peripheral vascular disease, which currently requires no further surgical intervention. Conclusion. This case has clear implications for the management of chronic PVGI. It is vital to collect high-quality surgical specimens for microbiological analysis and empirical choices of antibiotics are unlikely to cover all potential pathogens. It may also be prudent to enquire about a history of acute gastroenteritis when assessing patients presenting with chronic PVGI.

    Background The causative pathogen is rarely identified in the emergency department (ED), since the results of cultures are usually unavailable. As a result, antimicrobial treatment may be overused. The aim of our study was to investigate the pathogens, risk factors of acute gastroenteritis, and predictors of acute bacterial gastroenteritis in the ED. Methods We conducted a matched case-control study of 627 stool samples and 612 matched pairs. Results Viruses (41.3%) were the leading cause of gastroenteritis, with noroviruses (32.2%) being the most prevalent, followed by bacteria (26.8%) and Giardia lamblia (12.4%). Taking antacids (adjusted odds ratio [aOR] 4.10; 95% confidence interval [CI], 2.57–6.53), household members/classmates with gastroenteritis (aOR 4.69; 95% CI, 2.76–7.96), attending a banquet (aOR 2.29; 95% CI, 1.64–3.20), dining out (aOR 1.70; 95% CI, 1.13–2.54), and eating raw oysters (aOR 3.10; 95% CI, 1.61–5.94) were highly associated with gastroenteritis. Elders (aOR 1.04; 05% CI, 1.02–1.05), those with CRP >10 mg/L (aOR 2.04; 95% CI, 1.15–3.62), or those who were positive for fecal leukocytes (aOR 2.04; 95% CI, 1.15–3.62) or fecal occult blood (aOR 1.97; 95% CI, 1.03–3.77) were more likely to be hospitalized in ED. In addition, presence of fecal leukocytes (time ratio [TR] 1.22; 95% CI, 1.06–1.41), abdominal pain (TR 1.20; 95% CI, 1.07–1.41), and frequency of vomiting (TR 0.79; 95% CI, 0.64–0.98) were significantly associated with the duration of acute gastroenteritis. Presence of fecal leukocytes (aOR 2.08; 95% CI, 1.42–3.05), winter season (aOR 0.45; 95% CI, 0.28–0.74), frequency of diarrhea (aOR 1.69; 95% CI, 1.01–2.83), and eating shrimp or crab (aOR 1.53; 95% CI, 1.05–2.23) were highly associated with bacterial gastroenteritis. The area under the receiver operating characteristic curve of the final model was 0.68 (95% CI, 0.55–0.63). Conclusions Acute bacterial gastroenteritis was highly associated with season

    Full Text Available Background. Rotavirus (RV is the commonest pathogen in the hospital and primary care settings, followed by Adenovirus (AV and Norovirus (NV. Only few studies that assess the burden of RV gastroenteritis at the community level have been carried out. Objectives. To estimate incidence, disease characteristics, seasonal distribution, and working days lost by parents of RV, AV, and NV gastroenteritis leading to a family pediatrician (FP visit among children < 5 years. Methods. 12-month, observational, prospective, FP-based study has been carried out using Pedianet database. Results. RVGE incidence was 1.04 per 100 person-years with the highest incidence in the first 2 years of life. Incidences of AVGEs (1.74 and NVGEs (1.51 were slightly higher with similar characteristics regarding age distribution and symptoms. Risk of hospitalisation, access to emergency room (ER, and workdays lost from parents were not significantly different in RVGEs compared to the other viral infections. Conclusions. Features of RVGE in terms of hospitalisation length and indirect cost are lower than those reported in previous studies. Results of the present study reflect the large variability of data present in the literature. This observation underlines the utility of primary care networks for AGE surveillance and further studies on community-acquired gastroenteritis in children.

    1998-01-01

    Full Text Available Eine genetische Grundlage der Osteoporose wird neben Umwelteinflüssen seit langem vermutet. Bei Familien- und Zwillingsuntersuchungen wurden erbliche Einflüsse von etwa 46-75 % auf die Knochendichte - abhängig von den Meßorten - festgestellt. Neben einer genetischen Belastung durch eine betroffene Mutter wurde auch ein väterlicher Einfluß auf die Ausprägung der individuellen Knochendichte nachgewiesen. Verschiedenste Kandidatengene wurden bisher untersucht. Bedeutende Beiträge dazu sind in den genetischen Polymorphismen von Östrogen- und anderen Hormonrezeptoren und anderen wichtigen Genorten zu sehen. Eine Durchleuchtung des genetischen Hintergrundes der Osteoporose kann in Zukunft verbesserte Möglichkeiten der Früherkennung und Differenzierung der Diagnostik eröffnen und damit zu neuen Strategien für Prophylaxe und Therapie der Osteoporose führen.

    Objectives More than 900 students and teachers at many schools in Jiaxing city developed acute gastroenteritis in February 2014. An immediate epidemiological investigation was conducted to identify the pathogen, infection sources and route of transmission. Methods The probable cases and confirmed cases were defined as students or teachers with diarrhoea or vomiting present since the term began in February 2014. An active search was conducted for undiagnosed cases among students and teachers. Details such as demographic characteristics, gastrointestinal symptoms, and drinking water preference and frequency were collected via a uniform epidemiological questionnaire. A case-control study was implemented, and odds ratios (ORs) and 95% confidence intervals were calculated. Rectal swabs from several patients, food handlers and barrelled water factory workers, as well as water and food samples, were collected to test for potential bacteria and viruses. Results A total of 924 cases fit the definition of the probable case, including 8 cases of laboratory-confirmed norovirus infection at 13 schools in Jiaxing city between February 12 and February 21, 2014. The case-control study demonstrated that barrelled water was a risk factor (OR: 20.15, 95% CI: 2.59–156.76) and that bottled water and boiled barrelled water were protective factors (OR: 0.31, 95% CI: 0.13–0.70, and OR: 0.36, 95% CI: 0.16–0.77). A total of 11 rectal samples and 8 barrelled water samples were detected as norovirus-positive, and the genotypes of viral strains were the same (GII). The norovirus that contaminated the barrelled water largely came from the asymptomatic workers. Conclusions This acute gastroenteritis outbreak was caused by barrelled water contaminated by norovirus. The outbreak was controlled after stopping the supply of barrelled water. The barrelled water supply in China represents a potential source of acute gastroenteritis outbreaks due to the lack of surveillance and supervision

    The chlorination of public water supplies has led researchers to largely discard drinking water as a potential source of gastroenteritis outbreaks. The aim of this study was to investigate an outbreak of waterborne disease associated with drinking water from public supplies. A historical cohort study was carried out following notification of a gastroenteritis outbreak in Baqueira (Valle de Arán, Spain). We used systematic sampling to select 87 individuals staying at hotels and 67 staying in apartments in the target area. Information was gathered on four factors (consumption of water from the public water supply, sandwiches, water and food in the ski resorts) as well as on symptoms. We assessed residual chlorine in drinking water, analyzed samples of drinking water, and studied stool cultures from 4 patients. The risk associated with each water source and food type was assessed by means of relative risk (RR) and 95% confidence intervals (CI). The overall attack rate was 51.0% (76/149). The main symptoms were diarrhea 87.5%, abdominal pain 80.0%, nausea 50.7%, vomiting 30.3%, and fever 27.0%. The only factor associated with a statistically significant risk of disease was consumption of drinking water (RR = 11.0; 95% CI, 1.6-74.7). No residual chlorine was detected in the drinking water, which was judged acceptable. A problem associated with the location of the chlorinator was observed and corrected. We also recommended an increase in chlorine levels, which was followed by a reduction in the number of cases. The results of stool cultures of the four patients were negative for enterobacteria. This study highlights the potential importance of waterborne outbreaks of gastroenteritis transmitted through drinking water considered acceptable and suggests the need to improve microbiological research into these outbreaks (viruses and protozoa detection).

Die komplexen Auswirkungen auf die Klinik der Parodontologie und Implantologie werden im vorliegenden Beitrag beispielhaft dargestellt. Vitamin D3 fördert die Heilung nach Parodontalchirurgie. Bisphosphonate können die parodontale Situation während der Nachsorgetherapie verbessern und möglicherweise die Einheilung von dentalen Implantaten fördern. Die meisten klinischen Studien zeigen keine negativen Effekte in Bezug auf die Entstehung von Osteonekrosen des Kieferknochens. Die Bedeutung von Strontium für die Zahnheilkunde ist primär in der Kariesprävention angesiedelt. Erste klinische Pilotstudien unterstützen eine mögliche Wirkung von Teriparatid auf die Einheilung dentaler Implantate. Bedeutsam erscheinen die positiven Effekte von Teriparatid bei der Regeneration nach chirurgischer Parodontaltherapie. Die vorliegenden Studien zeigen, dass die pharmakologische Osteoporosetherapie einen positiven Einfluss auf die Klinik der Parodontologie und Implantologie haben kann.

    From the interplay of the energy-economic regulatory framework it follows that no drawbacks must arise from a change of ownership for either the utility that sells part of its transmission line system or the power customers. In the procedure commonly adopted in energy-economic practice for assessing the current market value of power mains, assessment errors having a contrary effect are tolerated in establishing the takeover price in order to reach a consensus. In this way, if profit losses have occurred in the past due to power pricing with excessive and premature reimbursements to customers for grants received towards construction costs (these reimbursements being mandatory under the code of financial practice but implicitly faulty), these losses are compensated for in the net sales price. As a consequence, however, future power prices need to be higher if they are to cover costs. As is demonstrated in the paper, the current market value, which is defined as Sieben`s material asset value, takes into account past costs that were not covered by profits from power sales. In other words, the utility that sells its power mains at a price corresponding to the current market value does not incur an implicit loss or gain, nor does the change in ownership of the power mains involve charges to customers. (orig./RHM) [Deutsch] Aus dem Zusammenspiel der energiewirtschaftlichen Rahmenordnung folgt insgesamt, dass der Versorgerwechsel weder zum Nachteil fuer das abgebende EVU noch zum Nachteilen fuer die Abnehmer/Verbraucher fuehren darf. Das in der energiewirtschaftlichen Praxis uebliche Verfahren der Sachzeitwertermittlung nimmt zum Erreichen eines Konsenses bezueglich des Uebergabepreises entgegengerichtete Bewertungsfehler in Kauf.

    Dresp, Joachim H.

    Im Bereich der Augenheilkunde findet sich die weltweit am häufigsten ausgeführte chirurgische Massnahme, die operative Behandlung des Grauen Stars: die Katarakt. Bei der Katarakt handelt es sich um eine Eintrübung der natürlichen Augenlinse, die sich je nach Stadium der Erkrankung leicht opak, über milchig bis zu bräunlich präsentiert. Mit dieser Zunahme der Undurchlässigkeit für das sichtbare Licht geht eine Abnahme des Sehvermögens einher, die bis zur totalen Erblindung führen kann. Bedingt durch die sehr eingeschränkten chirurgischen Möglichkeiten in den Ländern der Dritten Welt ist die Katarakt die Erblindungsursache Nummer 1 in der Welt. Ganz im Gegensatz hierzu ist in den industrialisierten Ländern Europas, Amerikas und Asiens die Katarakt-OP die sicherste chirurgische Intervention. In der Augenheilkunde werden Implantate aller drei Aggregatszustände verwendet.

    Full Text Available Abstract Background HIV-infected and HIV-exposed, uninfected infants experience a high burden of infectious morbidity and mortality. Hospitalization is an important metric for morbidity and is associated with high mortality, yet, little is known about rates and causes of hospitalization among these infants in the first 12 months of life. Methods Using data from a prevention of mother-to-child transmission (PMTCT trial (India SWEN, where HIV-exposed breastfed infants were given extended nevirapine, we measured 12-month infant all-cause and cause-specific hospitalization rates and hospitalization risk factors. Results Among 737 HIV-exposed Indian infants, 93 (13% were HIV-infected, 15 (16% were on HAART, and 260 (35% were hospitalized 381 times by 12 months of life. Fifty-six percent of the hospitalizations were attributed to infections; gastroenteritis was most common accounting for 31% of infectious hospitalizations. Gastrointestinal-related hospitalizations steadily increased over time, peaking around 9 months. The 12-month all-cause hospitalization, gastroenteritis-related hospitalization, and in-hospital mortality rates were 906/1000 PY, 229/1000 PY, and 35/1000 PY respectively among HIV-infected infants and 497/1000 PY, 107/1000 PY, and 3/1000 PY respectively among HIV-exposed, uninfected infants. Advanced maternal age, infant HIV infection, gestational age, and male sex were associated with higher all-cause hospitalization risk while shorter duration of breastfeeding and abrupt weaning were associated with gastroenteritis-related hospitalization. Conclusions HIV-exposed Indian infants experience high rates of all-cause and infectious hospitalization (particularly gastroenteritis and in-hospital mortality. HIV-infected infants are nearly 2-fold more likely to experience hospitalization and 10-fold more likely to die compared to HIV-exposed, uninfected infants.

    Strukturbrüche sind eine der Hauptursachen für die Schwierigkeiten vieler Unternehmen, ihre Organisationsform zu modernisieren und vor allem turbulenten Marktbedingungen anzupassen. Klassische Beispiele für Strukturbrüche finden sich in der Spaltung von Aufbau- und Ablauforganisation, der Spaltung von Produktion und Dienstleistung oder der Spaltung von Planung und Ausführung. Ein wirkungsvoller Ansatz zur Überwindung solcher Spaltungen ist eine Art Versöhnungsmuster: die Polare Organisation. Wesentliche Elemente dieser Organisationsform sind ihr Netzwerkcharakter, kooperatives Zusammenwirken, eine hohe Kommunikationsintensität und eine polare Koppelung der kommunizierenden Partner oder - in abstrahierter Form - die organisierte Balance erfolgskritischer Gegensätze, wie Kosten und Qualität.

    Bei der Dosimetrie von Photonenstrahlungen mit luftgefüllten Ionisationskammern werden in diesem Kapitel zwei Grenzfälle unterschieden. Der eine Fall ist die Bedingung des so genannten Sekundärelektronengleichwichts im Kammervolumen. In diesem Fall bestimmen ausschließlich die Photonen im Messvolumen die dosimetrische Anzeige. Der zweite Grenzfall ist gegeben, wenn das Luftvolumen und die Kammer das Strahlungsfeld im Phantom so wenig stören, dass der Sekundärelektronenfluss unverändert bleibt. Diese Bedingungen nennt man BRAGG-GRAY-Bedingungen. Beide Grenzfälle sind in der Praxis nur näherungsweise zu verwirklichen. Abweichungen müssen durch entsprechende Korrekturen oder Kalibrierungen berücksichtigt werden.

Damit vermittelt diese Darstellung im historischen Kontext ein tieferes Verständnis des physikalischen Denkens von der Antike bis heute und lotet zugleich die Dimension der Genesis physikalischer Begriffe aus, die in modernen Lehrbüchern zumeist nicht dargelegt wird. Das Credo Kuhns: Wer über die handwerkliche Handhabung von Physik hinausgehen will, muss sich zwingend mit der Frage befassen, was physikalisches Denken ausmacht und wie es entstanden ist. Die vorliegende zweite Auflage wurde ergänzt durch ein Vorwort von Prof. Dr. Oliver Schwarz, der im Institut Wilfried Kuhns forschen konnte und dabei dessen Denk- und Arbeitsweisen kennengelernt hat.

Die von den Lehrenden vorgelebten verinnerlichten Dispositionen im handlungsspezifischen Umgang mit unterschiedlichen Medien als auch der zu Grunde liegende „legitime Geschmack“, in dem sich diese Veranlagungen ausdrücken, sind hierbei bedeutsam. Die Rekonstruktion des medialen Habitus von LehrerInnen wird durch einen Vergleich zweier divergierender Unterrichtskonzeptionen mit der Methode der Videoanalyse erreicht. Das mediendidaktische Design, die Mediennutzung und die aktive Unterrichtsbeteiligung stellen die Analyseschwerpunkte dar, die der Beschreibung der verinnerlichten Dispositionen aufgrund der vorgelebten Haltungen und Wertvorstellungen dienen. Die anschließende relationierte Beobachtung ermöglicht es, in Anlehnung an die Habitustypen von Mutsch, die Differenzen und Gemeinsamkeiten der Unterrichtskonzepte sowie der daraus resultierenden Chancen und Schwierigkeiten im Unterricht zu verdeutlichen. This study attempts to show the correlation between school and media based on media habits, experiences and patterns of media usage of teachers and pupils in primary schools. As a theoretical framework, Bourdieu’s conception of habitus and the conception of media habitus of Kommer and Biermann are used to reconstruct the media habitus of primary school teachers in different educational settings. In this research, media habitus is understood as a combination of media economic capital, media activities, experience and preferences, values and attitudes of media in daily routine just as purposes and motives of media usage and educational intervention in family life.

    Full Text Available Introduction: In May 2014 an outbreak of norovirus occurred among patrons of a restaurant in Melbourne, Australia. Investigations were conducted to identify the infectious agent, mode of transmission and source of illness, and to implement controls to prevent further transmission. Methods: A retrospective case-control study was conducted to test the hypothesis that food served at the restaurant between 9 and 15 May 2014 was the vehicle for infection. A structured questionnaire was used to collect demographic, illness and food exposure data from study participants. To ascertain whether any food handlers had experienced gastroenteritis symptoms and were a possible source of infection, investigators contacted and interviewed staff who had worked at the restaurant between 9 and 16 May 2014. Results: Forty-six cases (including 16 laboratory-confirmed cases of norovirus and 49 controls were interviewed and enrolled in the study. Results of the analysis revealed a statistically significant association with illness and consumption of grain salad (OR: 21.6, 95% CI: 1.8–252.7, p = 0.015 and beetroot dip (OR: 22.4, 95% CI: 1.9–267.0, p = 0.014. An interviewed staff member who reported an onset of acute gastrointestinal illness on 12 May 2014 had prepared salads on the day of onset and the previous two days. Discussion: The outbreak was likely caused by person-to-food-to-person transmission. The outbreak emphasizes the importance of the exclusion of symptomatic food handlers and strict hand hygiene practices in the food service industry to prevent contamination of ready-to-eat foods and the kitchen environment.

    1997-06-27

    A wedding reception at a North Yorkshire hotel was followed by an explosive outbreak of gastroenteritis. The attack rate among the 111 guests was 50% and vomiting was a predominant feature. The results of laboratory and epidemiological investigations were consistent with a common source outbreak of small round structured virus (SRSV) infection genotype II. The source of the outbreak was traced to a kitchen assistant who suddenly became ill on the eve of the reception and vomited into a sink used for preparing vegetables. The sink was cleaned with a chlorine based disinfectant and used the next morning to prepare a potato salad, subsequently identified as the vehicle of infection in a cohort study of guests (odds ratio 3.21; CI 1.78-5.78, p = 0.0001). No other food was associated with illness. The outbreak provides further supporting evidence of the importance of vomiting in the transmission of SRSV infection, highlights the virulence of this group of viruses, and indicates their relative resistance to environmental disinfection and decontamination. It also highlights the need for the adequate training of catering staff and the implementation and enforcement of food hygiene regulations.

    A controlled, randomised trial comparing the results of oral rehydration therapy with those of intravenous fluid treatment in 470 children with severe gastroenteritis was undertaken. The oral rehydration therapy was divided into two phases--a rehydration phase that used high sodium isotonic fluid at 40 ml/kg per hour and a maintenance phase using low sodium isotonic fluid (sodium 40, potassium 30, bicarbonate 25, chloride 45, and dextrose 130 mmol/l). The results indicate that oral rehydration treatment, used according to this protocol, is successful in treating severe diarrhoea and dehydration, and has considerable advantages over intravenous fluid therapy in reducing complications associated with the treatment of hypernatraemia, in promoting rapid correction of hypokalaemia and acidosis, in decreasing the duration of diarrhoea, and in promoting a greater weight gain at hospital discharge.

    Full Text Available Background Urinary tract infection (UTI is the second most common bacterial infection in infancy and childhood with peaking in infancy and toilet training. Objectives The current study aimed to investigate UTI in patients with diarrhea. Patients and Methods This case-control study was conducted on 200 participants, 100 were patients with acute gastroenteritis and the other 100 were controls who referred to the clinic for routine checkup. UTI was defined as two positive urine cultures with > 105 cfu/mL. If white blood cells were more than 10/mm3 in un-centrifuged urine it would be considered pyuria and more than one microorganism in 10 oil immersion fields as bacteriuria. Analysis was conducted using SPSS ver. 16 with application of chi-square test and 0.05 as significant levels. Results The distribution of these 200 children were 115 (57.5% and 85 (42.5% for females and males respectively. The gender and age distribution in case and control groups showed non-significant association. In urine culture it was observed that 27 individuals were positive and there were seven healthy children. The number of children with positive urine culture was higher than that of their counterparts significantly (P = 0.0001. Relationship between urine culture and age groups showed that the number of participants with positive urine culture was higher in children with age of two months to two years but it was not significant (P = 0.54. Conclusions It was demonstrated that, considerable percentage of UTI existed in the gastroenteritis diseases. Early treatment of UTI in patients would reduce UTI complications.

    In January 1995, Florida experienced the largest outbreak of oyster-associated gastroenteritis ever reported. We interviewed both the cohort of persons from 38 gatherings where illness was reported and a sample of harvesters and harvest-area residents. Oysters were traced by means of tags and dealer records, and water quality measures in harvest areas were reviewed. We examined stool specimens for small round structured viruses by means of electron microscopy and amplification of RNA by reverse-transcriptase polymerase chain reaction. We also tested serum specimens for antibodies to Norwalk virus. Of 223 oyster eaters, 58% (129/223) became ill, compared with 3% (2/76) of non-oyster eaters (relative risk, 22; 95% confidence interval, 5.6-87.0). Most oyster eaters (67% [149/223]) ate only cooked (grilled, stewed, or fried) oysters. Oyster eaters who reported eating only thoroughly cooked oysters were as likely to become ill as those who ate raw oysters (relative risk, 0.68; 95% confidence interval, 0.45-1.0; P = .1). In 29 clusters, implicated oysters were from Apalachicola Bay, Florida. A community outbreak occurred in 2 bayside communities before the oyster harvest, leading to an increase in the reportedly common practice of overboard dumping of feces. Small round structured viruses were identified in the stool specimens of 2 harvest-area residents and 9 persons from 8 clusters. Results of water quality tests for fecal coliforms were within acceptable limits. This large outbreak of gastroenteritis associated with oysters may have resulted from overboard dumping of feces during a community outbreak of diarrheal illness. Our findings of acceptable water quality measures for fecal contamination and the lack of appreciable protective effect from cooking leave the consumer with no assurance of safety.

    Full Text Available In our contemporary society which humanistic emotions are corrupting due to increase in technological advances, there is a need for effective value education to train persons who are honest ambitious, hardworking and capable of empathy, who have respect for each other without losing feelings of love and tolerance, who give very importance to science and rationalism. Schools are social institutions which enable the continuity of society by transmission of national and universal values. The course textbooks, which are an indispensable part of education process, have an important role in the transmission of values. Students gain national and universal values through the literary works in course textbooks which are established by benefiting from the richness of mother tongue and its vocabulary. The purpose of this study is to determine which national and universal values are delivered through the reading texts of Primary Education 6th, 7th and 8th grade Turkish textbooks, and to determine how these values are distributed at 6th, 7th and 8th grade Turkish textbooks. This study used document analysis method which is a qualitative research method. The sample of the survey is established of 6th, 7th and 8th grade Turkish textbooks which are published by National Education Ministry (MEB. By examining reading texts in the textbooks according to “Values Assessment Form (VAF”, it is tried to determine which national and universal values are delivered through texts. In this study, it is found that, texts at MEB 6th, 7th and 8th grade Turkish textbooks did not deliver values at the desired level and value transmission is more intense at 6th grade and has been reduced at 7th and 8th grades Teknolojik gelişmelere paralel olarak insanî duyguların köreldiği günümüz toplumlarında, birbirlerine karşı saygı, sevgi ve hoşgörü duygularını kaybetmeden bilimselliğe ve akılcılığa önem veren, empati kurabilen, azimli, çalışkan ve d

    The electric power industry in the United States is undergoing dramatic change. Once totally controlled by utilities that had monopolistic holds on the supply, transmission and distribution of electricity in their service areas, the electric power system is being deregulated, introducing competition among electricity providers who can distinguish themselves by price, services and other factors. The new electric power system will feature advanced technologies and services that can be used on-site or located in close proximity to the load, instead of depending solely upon large, central station generation and transmission. Using a variety of advanced modular generating technologies (including small-scale renewables), distributed energy resource (DER) plants supply base-load power, peaking power, backup power, remote power and/or heating and cooling, and in some cases supply higher and more reliable quality power. Currently, DER represent a minor part of the electric supply system. If the potential of DER is to be realized in the new electric power market, a full understanding of the value and benefits these technologies provide to the electric system is necessary. This report includes 30 key quantitative studies reporting on the values and benefits of distributed energy generation technologies (including renewables) in various applications, as well as a matrix that permits key comparisons.

    unstoppable. In response, energy providers will be forced to both fully acknowledge the trend and plan for accommodating DER [3]. With bureaucratic barriers [4], lack of time/resources, tariffs, etc. still seen in certain regions of the country, changes still need to be made. Given continued technical advances in DER, the time is fast approaching when the industry, nation-wide, must not only accept DER freely but also provide or review in-depth technical assessments of how DER should be integrated into and managed throughout the distribution system. Characterization studies are needed to fully understand how both the utility system and DER devices themselves will respond to all reasonable events (e.g., grid disturbances, faults, rapid growth, diverse and multiple DER systems, large reactive loads). Some of this work has already begun as it relates to operation and control of DER [5] and microturbine performance characterization [6,7]. One of the most urgently needed tools that can provide these types of analyses is a distribution network analysis program in combination with models for various DER. Together, they can be used for (1) analyzing DER placement in distribution networks and (2) helping to ensure that adequate transmission reliability is maintained. Surveys of the market show products that represent a partial match to these needs; specifically, software that has been developed to plan electrical distribution systems and analyze reliability (in a near total absence of DER). The first part of this study (Sections 2 and 3 of the report) looks at a number of these software programs and provides both summary descriptions and comparisons. The second part of this study (Section 4 of the report) considers the suitability of these analysis tools for DER studies. It considers steady state modeling and assessment work performed by ORNL using one commercially available tool on feeder data provided by a southern utility. Appendix A provides a technical report on the results of

    Bender, Brenda J; Ozuah, Philip O

    2004-04-01

    For treatment of mild to moderate dehydration arising from viral gastroenteritis, the American Academy of Pediatrics recommends oral rehydration therapy over a 4-hour period. However, oral rehydration therapy remains largely underused by emergency physicians. Studies suggest that a major barrier is a perception that the time requirement for oral rehydration therapy is too long relative to intravenous (IV) hydration. : To test the hypothesis that children who receive IV hydration for gastroenteritis spend significantly less than 4 hours in the emergency department (ED). A prospective case series involving a consecutive sample of 549 children treated with IV hydration for mild to moderate dehydration at an urban pediatric ED. Treatment time was defined as period elapsed between when a physician placed a patient in an ED room and when he/she discharged the patient. We excluded time spent in the waiting room before seeing a physician. Using a standardized procedure, we collected data in September/October 2000 (fall), November 2000 to January 2001 (winter), and April/May 2001 (spring). To provide a measure of average pass-through time at this ED, we also collected data on all patients treated during consecutive 7-day periods in the fall (n = 502), winter (n = 776), and spring (n = 653). We performed univariate analysis of continuous variables using t tests for independent samples. 549 subjects received IV treatment for dehydration; of whom 55% were female, and mean age was 9.7 years. Treatment time for patients undergoing IV hydration exceeded 4 hours (mean = 5.4 +/- 2.4 hours; median = 5.0 hours). Mean time for IV treatment of dehydration was significantly longer than the mean time for treating other patients (5.4 vs. 1.2 hours, P Pediatrics for oral rehydration. The data did not support the perception by emergency physicians that children treated with IV hydration spend significantly less time than 4 hours in the ED. These findings have implications for addressing one

    Full Text Available Background: Enteric viruses (mainly rotaviruses are the most common cause of infectious diarrhea in infants. One  of the  pathophysiologic mechanisms in rotaviral gastroenteritis is the  reduction of the  surface  activity of enterocyte disaccharidases  and  osmotic  diarrhea. Aim: To determine the clinical significance of metabolic activity of intestinal microbiota in the formation of the osmotic component of viral diarrhea in children of various ages. Materials and methods: The study involved 139 children aged  from 1 month  to 14 years admitted to the hospital in the first 24 to 72 hours of moderate-degree  viral gastroenteritis.  Rotaviral infection was the most prevalent  (90%. Viral etiology was confirmed  by the  reaction  of indirect hemagglutination and multiplex real-time PCR (in feces. Total carbohydrate content in the feces was measured and fecal microflora was investigated by two methods: bacteriological and gas liquid chromatography with the determination of short-chain fatty acids. Results: The mean carbohydrate content in the feces of children below 1.5 years of age was higher than  that  in older children (p = 0.014. There was an inverse correlation between the concentration of rotaviral antigens  and carbohydrate   contents (r = -0,43, p < 0.05 and the production of acetic and propionic acids (R = -0,35, p < 0.01.

    Food handlers play an important role in the transmission of norovirus (NoV) in food-borne outbreaks of gastroenteritis (GE). In a year-round prevalence study, the prevalence of NoV in catering companies without recently reported outbreaks of GE was investigated and compared to the observed prevalence in catering companies with recently reported outbreaks. Swab samples were collected from surfaces in the kitchens and (staff) bathrooms in 832 randomly chosen companies and analyzed for the presence of NoV RNA. In total, 42 (1.7%) out of 2,496 environmental swabs from 35 (4.2%) catering companies tested positive. In contrast, NoV was detected in 147 (39.7%) of the 370 samples for 44 (61.1%) of the 72 establishments associated with outbreaks of gastroenteritis. NoV-positive swabs were more frequently found in winter, in specific types of companies (elderly homes and lunchrooms), and in establishments with separate bathrooms for staff. We found a borderline association with population density but no relation to the number of employees. Sequence analysis showed that environmental strains were interspersed with strains found in outbreaks of illness in humans. Thus, the presence of NoV in catering companies seemed to mirror the presence in the population but was strongly increased when associated with food-borne GE. Swabs may therefore serve as a valuable tool in outbreak investigations for the identification of the causative agent, although results should be interpreted with care, taking into account all other epidemiological data.

    Oral rehydration is the standard in most current guidelines for young children with acute gastroenteritis (AGE). Failure of oral rehydration can complicate the disease course, leading to morbidity due to severe dehydration. We aimed to identify prognostic factors of oral rehydration failure in children with AGE. A prospective, observational study was performed at the Emergency department, Erasmus Medical Centre, Rotterdam, The Netherlands, 2010-2012, including 802 previously healthy children, ages 1 month to 5 years with AGE. Failure of oral rehydration was defined by secondary rehydration by a nasogastric tube, or hospitalization or revisit for dehydration within 72 hours after initial emergency department visit. We observed 167 (21%) failures of oral rehydration in a population of 802 children with AGE (median 1.03 years old, interquartile range 0.4-2.1; 60% boys). In multivariate logistic regression analysis, independent predictors for failure of oral rehydration were a higher Manchester Triage System urgency level, abnormal capillary refill time, and a higher clinical dehydration scale score. Early recognition of young children with AGE at risk of failure of oral rehydration therapy is important, as emphasized by the 21% therapy failure in our population. Associated with oral rehydration failure are higher Manchester Triage System urgency level, abnormal capillary refill time, and a higher clinical dehydration scale score.

    Full Text Available Cases of benign infantile convulsions with mild gastroenteritis (BICE treated in our hospital from 2008 to 2012 were analyzed retrospectively. Among the 65 cases of convulsions with acute diarrhea, there were 18 cases of BICE, 15 cases of febrile seizures, 13 cases of epilepsy, 6 cases of viral encephalitis, 6 cases of hyponatremia encephalopathy, 3 cases of hypernatremia encephalopathy, 2 cases of toxic encephalopathy, and 2 cases of hypocalcemia convulsion. The convulsion occurred mostly during the first 2 d of the illness and was in a generalized tonic or tonic-clonic form.

    Clinical assessment of dehydration in children with acute gastroenteritis (AGE) is crucial for treatment. The gold standard for assessment is acute weight loss. Dehydration severity, as determined by weight loss, significantly correlates with serum urea nitrogen (UN) in children with AGE. The disadvantage of using serum UN as a marker of dehydration severity, however, is that the level can be affected by nutrition. Serum uric acid (UA) theoretically could serve as an alternative in this regard, but there have been no reports on the direct relationship between serum UA and weight loss. The aim of this study was therefore to assess the relationship between serum UA and weight loss in patients with AGE. This was a prospective observational study of children 1-71 months of age admitted to Tokyo Metropolitan Children's Medical Center with AGE between 1 December 2010 and 31 March 2015. Patients with symptoms of AGE ≥ 8 days, chronic disease, or incomplete data were excluded from the study. Pre-post-rehydration weight change was used as an alternative, gold standard marker for the assessment of dehydration severity. The study participants consisted of 97 children. Serum UA correlated significantly with weight change, and increased significantly along with dehydration severity. Serum UA can be considered as an adjunct to the clinical assessment of dehydration in children with AGE. © 2017 Japan Pediatric Society.

    Pediatric acute gastroenteritis (AGE) is a common condition with high health care utilization, persistent practice variation, and substantial family burden. An initial approach to resolve these issues is to understand the patient/caregiver experience of this illness. The objective of this study was to describe caregivers' experiences of pediatric AGE and identify their information needs, preferences, and priorities. A qualitative, descriptive study was conducted. Caregivers of a child with AGE were recruited for this study in the pediatric emergency department (ED) at a tertiary hospital in a major urban centre. Individual interviews were conducted (n=15), and a thematic analysis of interview transcripts was completed using a hybrid inductive/deductive approach. Five major themes were identified and described: 1) caregiver management strategies; 2) reasons for going to the ED; 3) treatment and management of AGE in the ED; 4) caregivers' information needs; and 5) additional factors influencing caregivers' experiences and decision-making. A number of subthemes within each major theme were identified and described. This qualitative descriptive study has identified caregiver information needs, preferences, and priorities regarding pediatric AGE. This study also identified inconsistencies in the treatment and management of pediatric AGE at home and in the ED that influence health care utilization and patient outcomes related to pediatric AGE.

    In Catalonia the current surveillance systems do not allow to know the true incidence or the health care utilization of acute gastroenteritis (AGE) caused by Campylobacter and Salmonella infections. The aim of this study is to analyze these characteristics. Descriptive study of Campylobacter and Salmonella infections reported in 2002 and 2012 in Catalonia, Spain. We included cases isolated and reported by the laboratory to a regional Surveillance Unit. The estimated incidence of Salmonella and Campylobacter AGE decreased by almost 50% and 20% respectively in 2012. Children between one and 4 years old were the most affected in both years. Significant differences in the clinical characteristics and disease duration were observed between Campylobacter and Salmonella. Visits to the Emergency Department and hospitalization rates were 63.7% and 15%, being more frequent among salmonellosis cases. The estimated incidence of Campylobacter and Salmonella infections has decreased, however rates are still important, as well as it is the health care utilization in both diseases. Current surveillance systems need appropriateness improvements to reach a better control of these infections. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

    Since 2006, two new vaccines have been licensed to prevent rotavirus, the cause of 20% to 50% of severe acute gastroenteritis in young children worldwide. These vaccines have been implemented in national immunization programs in about 30 high- and middle-income countries, including the United States, and vaccine use has led to substantial decreases in diarrhea-related health care visits. In addition to reductions in diarrhea burden in vaccinated children, decreases have been observed in older, unvaccinated age groups in many settings, suggesting indirect benefits (i.e., herd immunity) from vaccination. Although the efficacy of these oral rotavirus vaccines is expectedly lower in developing countries in Asia and Africa, the public health benefits of vaccination in these settings, where more than 90% of the estimated 453,000 annual deaths from rotavirus occur, are likely to be substantial. Efforts continue to develop alternative rotavirus vaccines that could have a better efficacy and safety profile and may be less expensive. PMID:23303967

Auch die steuerlichen Erhebungslasten fordern eine Vereinfachung des materiellen Rechts: Selbst wenn die Mitwirkungspflichten, die Lenkungswirkungen, auch die steuerstrafrechtlichen Vorgaben und datenrechtlichen Lasten isoliert betrachtet noch zumutbar wären, verletzt jedenfalls deren Kumulation das verfassungsrechtliche Maß. Schließlich wird der Kampf gegen „aggressive Steuerplanungen“ internationaler Unternehmen nur erfolgreich sein, wenn das anzuwendende Steuerrecht grundlegend vereinfacht wird. Diese Reformforderungen werden durch die historischen Motive der Soll-Ertragsbesteuerung bestätigt: Steuerhinterziehungen sollten vermieden, die Privatsphäre der Steuerpflichtigen sollte geschont und jeder gleichheitsgerecht zur Steuer herangezogen werden. Das geltende Steuerrecht belastet zu Recht den tatsächlichen, den Ist-Ertrag. Die geltende unübersichtliche Konkretisierung dieses Ausgangspunktes durch Elemente der Soll-Ertragsbesteuerung ist aber in einer grundlegenden Vereinfachung des Steuerrechts zu rationalisieren und zum System zu machen.

    1999-01-01

    To evaluate the use of stents for prolonging the patency of gastroenteric anastomoses (GEA) induced by magnet compression. Rare earth magnets were inserted perorally and serially in 15 dogs so as to mate across the gastric and jejunal walls. After magnet excretion, the resulting GEA was identified endoscopically, dilated (n = 1), and stented with bare (n = 2) or partially covered (n = 6) flared 10-mm or 12-mm Z stents. The GEA was followed at 2-4-week intervals for patency; malfunctioning shunts were irrigated, or dilated with angioplasty balloons. Gross and histologic examination of the anastomotic tissues was performed in 14 animals. Magnet pairs were excreted in 5-7 days. Of the 19 magnet placements in 15 animals, stent placement was not possible because of early GEA closure (n = 6), failure to locate (n = 2), pancreatic abscess (n = 1), and magnet perforation with peritonitis (n = 1). Estimated duration of GEA patency was 19 days after balloon dilation, 40-64 days with bare Z stents, and 58-147 days (mean, 90 days) with partially covered Z stents. Shunt function was commonly hindered by bezoars. Stent narrowing or occlusion was caused by tissue overgrowth through bare stents (n = 2), between covered stent struts and through partially detached membrane (n = 2). Serious morbidity (n = 2) was due to malpositioned magnets across the pancreas in one animal and gastric perforation in the other. One dog was euthanized because of unsuspected kidney infection. Partially covered stents significantly extend the anatomic patency rate of magnetic GEA to 7 weeks or more. Functional patency is frequently impaired by bezoars. Ongoing improvements in covered stent design should provide longer-term GEA patency.

Epidemiological and environmental investigation in Tangdar block (Kupwara district) and Uri Tehsil (Baramula district). Visits to villages affected by the earthquake, rehabilitation camps and health care, examination of cases with acute diarrhoeal disease (ADD), environmental observations, collection of clinical samples from ADD cases and environmental samples from drinking water sources, and laboratory methods. In total, 1783 cases of ADD were reported between 14 October and 17 December 2005 in Tangdar (population 65000). The overall attack rate was 20% in children under 4 years of age. Twelve cases of ADD with loose motions without blood were studied, and 11 rectal swabs and one stool sample were processed. No bacterial enteropathogens could be isolated, but three of the 12 samples yielded rotavirus antigen on enzyme-linked immunosorbent assay. Twelve of 13 (92.3%) water samples, collected from various stream or tap water (source: spring/stream) sources, were unsatisfactory (P=0.001) using the H(2)S strip method compared with other sources (well/mineral water). All eight water sources in Tangdar block were unsatisfactory, indicated by blackening of H(2)S filter paper strips. Following the earthquake, drinking stream water or tap water without boiling or chlorination may have led to a common source water-borne outbreak of rotavirus gastroenteritis. Other contributing factors were: overcrowding; poor sanitation; open-air defaecation; poor hygiene; and living in makeshift camps near streams. Person-to-person transmission may also have contributed to perpetuation of the outbreak.

    In January 2011, multiple acute gastroenteritis outbreaks that spanned many days and were related to attendance at funerals were reported to public health units in Quebec. An epidemiological investigation was initiated to identify the source of the contamination and to explain the extent of the contamination over time. Thirty-one cohorts of individuals attended different funerals held between 14 and 19 January. All attendees were served a cold buffet made by the same caterer. Of these 31 cohorts, 16 (with a total of about 800 people) contained individuals who reported being ill after the funeral. Symptoms were mainly diarrhea (89 to 94% of individuals), vomiting (63 to 90%,) and fever (26 to 39%), with a median incubation period of 29 to 33 h and a median duration of symptoms of 24 to 33 h, suggesting norovirus-like infection. Among the 16 cohorts, 3 were selected for cohort studies. Among those three cohorts, the mean illness rate was 68%. Associations were found between those who fell ill and those who had consumed pasta salad (relative risk [RR] = 2.4; P = 0.0022) and ham sandwiches (RR = 1.8; P = 0.0096). No food handlers reported being sick. No stool samples were provided by individuals who became ill. Environmental and food samples were all negative for causative agents. Although the causative agent was not clearly identified, this investigation raised many concerns about the importance of preventing foodborne transmission of viral gastroenteritis and generated some recommendations for management of similar outbreaks.

    The study aims to assess the risk of developing hyponatraemia when large-volume bolus fluid rehydration therapy is administered. We conducted a prospective randomised study in a tertiary-care centre emergency department. Participants included children with gastroenteritis and dehydration requiring intravenous rehydration. They were randomised to receive 60 mL/kg (large) or 20 mL/kg (standard) 0.9% saline bolus followed by maintenance 0.9% saline for 3 h. Biochemical tests were performed at baseline and 4 h. The primary outcome measure was the development of hyponatraemia at 4 h. Secondary outcome measures were (i) change in sodium relative to baseline value; (ii) magnitude of decrease among those who experienced a decrease; (iii) risk of hypernatraemia; (iv) correlations between urine parameters and hyponatraemia; and (v) fluid overload. Eighty-four of 224 (38%) participants were hyponatraemic at baseline. At 4 h, 22% (48/217) had a dysnatraemia, and similar numbers of children were hyponatraemic in both groups: large (23% (26/112)) versus standard (21% (22/105)) (P = 0.69). Among initially hyponatraemic children, 63% (30/48) who received large-volume rehydration and 44% (15/34) of those administered standard rehydration were isonatraemic at 4 h (P = 0.10). Overall, children who received 60 mL/kg experienced a larger mean increase (1.6 ± 2.4 mEq/L vs. 0.9 ± 2.2 mEq/L; P = 0.04) and were less likely to experience a sodium decrease of ≥2 mEq/L (8/112 vs. 17/105; P = 0.04) than those administered 20 mL/kg. Large-volume bolus rehydration therapy with 0.9% saline is safe. It does not promote the development of hyponatraemia over the short term, but hastens the resolution of baseline hyponatraemia. © 2013 The Authors.

Um Aussagen über die Wirksamkeit einzelner Therapieformen in der Behandlung dieser Erkrankung treffen zu können, untersuchten wir 24 Patientinnen mit neuromuskulärer Beckenbodenschwäche sowie 24 männliche Patienten nach Prostatektomie. In einer kontrollierten, prospektiven Längsschnittstudie erhielten je 8 Patienten jeder Diagnosegruppe nach randomisierter Zuordnung eine Serie Elektrostimulation der Beckenbodenmuskulatur (ES, Biofeedbacktherapie (BF und EMG-getriggerte Elektrostimulation (EMG-ES in Kombination mit einer standardisierten Krankengymnastik (KG. Hauptzielparameter ist der Harninkontinenzgrad, Nebenzielparameter die Häufigkeit der Inkontinenzepisoden und Beckenbodenspannung, gemessen über den Oberflächen-EMG-Bereich. In bezug auf den Harninkontinenzgrad sind die Ergebnisse am Studienende bei Einsatz der Feedbackverfahren signifikant besser als nach isolierter Elektrostimulation. Durch BF sank der Harninkontinenzgrad nach Ingelmann-Sundberg im Mittelwert von Therapiebeginn bis zum Ende des Follow-up um 1,2; nach EMG-ES um 1,05. Passive ES führte zu einer Harninkontinenzreduktion um 0,36.

    Tuberculosis (TB) is a granulomatous disease caused by Mycobacterium tuberculosis and transmission is via an airborne route by droplet infection. In the majority of cases patients have thoracic TB, which most frequently presents with hilar lymphadenopathy and pulmonary manifestation. Due to the rise in incidence of TB in central Europe to be expected over the coming years, it is essential to be acquainted with the radiological manifestations of pulmonary TB, particularly to be able to discriminate active from inactive TB. Due to the use of molecular techniques entailing DNA fingerprinting, the traditional classification of TB in primary and postprimary TB is being challenged. These genetic studies have revealed that variations in the clinical and radiographic appearance of TB are mainly affected by the immune status of the patients. Due to the low prevalence of TB in central Europe and the wide variation of radiological presentations, the diagnosis and therapy of TB is often delayed. In this article, the radiographic manifestations of thoracic TB are summarized and discussed. Together with the medical history and bacteriological tests, chest X-ray imaging and computed tomography (CT) play a major role not only in the detection of TB but also in the follow-up during and after therapy. Chest X-radiographs should be the primary diagnostic method in patients with suspected TB in screening as well as for diagnosis and therapy monitoring. The use of CT is more sensitive than chest radiographs and is frequently performed after chest radiographs to obtain detailed information about subtle parenchymal changes or lymph node manifestation. When active TB is suspected CT should be performed. Tree in bud, lobular consolidations, centrilobular nodules, cavities and ground-glass opacification are typical changes in active TB. (orig.)

    Gastroenteritis is one of the most common infectious diseases in the military populations and can diminish operational effectiveness and impede force readiness. The present study investigates the cause and the source of an acute gastroenteritis outbreak that occurred during a military exercise of the Portuguese Army, in February 2013. A retrospective investigation was performed and stool samples, food items and water were screened for common foodborne bacteria and viruses, namely Norovirus GI, Norovirus GII, Astrovirus, Rotavirus, Adenovirus and Sapovirus. From the total of 160 soldiers that participated in the military exercise 20 developed gastroenteritis (attack rate of 12.5%). Symptoms were predominantly vomiting (n=17, 85%) and diarrhoea (n=9, 45%). The first cases occurred 24-48h after drinking water from the creek, the plausible origin of the outbreak. The epidemic peak was registered 2 days after and the last cases 6 days after, upon returning to base. No pathogenic bacteria were found in stools however virological analysis revealed the presence of multiple enteropathogenic viruses, namely Norovirus GI (GI.3), Norovirus GII (GII.4 New Orleans 2009), Astrovirus and Sapovirus, as single or co-infections. Food and water samples were not tested for the presence of viruses due to exhaustion of samples on bacteriological analysis. To the best of our knowledge this is the first report of a viral gastroenteritis outbreak among military personnel in the Portuguese Army. Copyright © 2015 Elsevier B.V. All rights reserved.

    Acute gastroenteritis is common in childhood. The estimation of the degree of dehydration is essential for management of acute gastroenteritis. Plasma water was assessed as a diagnostic tool in children with acute gastroenteritis and dehydration admitted to hospital. In a prospective cohort study, 101 patients presenting at the emergency department with dehydration were included. Clinical assessment, routine laboratory tests, and plasma water measurement were performed. Plasma water was measured as a percentage of water content using dry weight method. During admission, patients were rehydrated in 12 h. Weight gain at the end of the rehydration period and 2 weeks thereafter was used to determine the percentage of weight loss as a gold standard for the severity of dehydration. Clinical assessment of dehydration was not significantly associated with the percentage of weight loss. Blood urea nitrogen (r = 0.3, p = 0.03), base excess (r =-0.31, p = 0.03), and serum bicarbonate (r = 0.32, p = 0.02) were significantly correlated with the percentage of weight loss. Plasma water did not correlate with the percentage of weight loss. On the basis of the presented data, plasma water should not be used as a diagnostic tool in the assessment of dehydration in children with acute gastroenteritis.

    Full Text Available Noroviruses (Norwalk-like viruses are an important cause of gastroenteritis worldwide. They are the most common cause of outbreaks of gastroenteritis in the adult population and occur in nursing homes for the elderly, geriatric wards, medical wards, and in hotel and restaurant settings. Food-borne outbreaks have also occurred following consumption of contaminated oysters. This study describes the application of a reverse transcription-polymerase chain reaction (RT-PCR assay using random primers (PdN6 and specific Ni and E3 primers, directed at a small region of the RNA-dependent RNA polymerase-coding region of the norovirus genome, and DNA sequencing for the detection and preliminary characterisation of noroviruses in outbreaks of gastroenteritis in children in Brazil. The outbreak samples were collected from children <5 years of age at the Bertha Lutz children's day care facility at Oswaldo Cruz Foundation (Fiocruz, Rio de Janeiro, that occurred between 1996 and 1998, where no pathogen had been identified. At the Bertha Lutz day care center facility, only Fiocruz's employee children are provided for, and they come from different social, economic and cultural backgrounds. Three distinct genogroup II strains were detected in three outbreaks in 1997/98 and were most closely related to genotypes GII-3 (Mexico virus and GII-4 (Grimsby virus, both of which have been detected in paediatric and adult outbreaks of gastroenteritis worldwide.

    Full Text Available Background: Three weeks after Typhoon Haiyan, an increasing number of acute gastroenteritis cases were reported in Kananga, Leyte, an area where evacuated residents had returned home two days after the disaster. An outbreak investigation was conducted to identify the source and risk factors associated with the increase of gastroenteritis. Methods: A case was defined as any person in Kananga who developed acute diarrhoea (≥ 3 times/24 hours and any of the following symptoms: fever, nausea, vomiting or abdominal pain from 11 November 2013 to 10 December 2013. Active case finding was conducted by reviewing medical records, and a case-control study was conducted. Rectal swabs and water samples were tested for bacteriological examination. Results: One hundred and five cases were identified. Multivariate analysis revealed that consumption of untreated drinking-water was associated with illness (adjusted odds ratio: 18.2. Both rectal swabs and municipal water samples tested positive for Aeromonas hydrophila. On inspection of the municipal water system, breaks in the distribution pipes were found with some submerged in river water. Conclusion: This acute gastroenteritis outbreak was most likely caused by Aeromonas hydrophila and transmitted through a contaminated water source. This study highlights that areas less damaged by a disaster that do not require ongoing evacuation centres can still have acute gastroenteritis outbreaks. All affected areas should be monitored during a disaster response, not just those with evacuation centres. Boiling or chlorinating of water should also be recommended for all areas affected by disaster.

The aim of the study is to compare the clinical effectiveness of the probiotics—Saccharomyces boulardii and Bifidobacterium lactis—in children who had been diagnosed with rotavirus gastroenteritis. Materials and methods. Seventy five patients aged between 5 months–5 years diagnosed as rotavirus gastroenteritis were included in the study. The patients diagnosed as rotavirus gastroenteritis by latex agglutination test in stool were divided into 3 groups of twenty-five patients each: First group was given oral rehydration therapy and rapid refeeding with a normal diet with Saccharomyces boulardii (spp. I-745, second group was given oral rehydration therapy and rapid refeeding with a normal diet with Bifidobacterium lactis (spp. B94, culture number:∘118529 and third group received only oral rehydration therapy and rapid refeeding with a normal diet. Results. The duration of diarrhea was shorter in the group given oral rehydration therapy and rapid refeeding with a normal diet with Bifidobacterium lactis and Saccharomyces boulardii than the group given only oral rehydration therapy and rapid refeeding with a normal diet. Conclusion. Bifidobacterium lactis has a complemental role in the treatment of rotavirus gatroenteritis and other probiotics may also have a beneficial effect in rotavirus gastroenteritis compared with the therapy included only oral rehydration therapy and rapid refeeding with a normal diet.

    Full Text Available OBJECTIVES: We investigated a nationwide outbreak of severe rotavirus gastroenteritis in Nicaragua in children under 5 years old, leading to many consultations, hospitalizations, and deaths. We questioned whether a vaccine might have prevented these illnesses and deaths, sought to identify risk factors for death, and developed a clinical profile of children hospitalized with diarrhea. METHODS: We conducted a case-control study to determine whether children who died had access to routine immunizations, a proxy predicting access to a rotavirus vaccine. We identified risk factors for death among children who died in the outbreak compared with surviving age-matched controls with diarrhea. We collected stools, clinical data, and immunization data on children hospitalized for diarrhea to test for rotavirus, develop the profile, and forecast future access to a rotavirus vaccine. RESULTS: The outbreak from February to April 2005 caused 47 470 consultations and 52 deaths. Approximately 80% of cases and controls and 60% of children hospitalized with diarrhea had access to routine immunizations and would likely have had access to a rotavirus vaccine. With a vaccine efficacy of 85%, up to 51% of severe rotavirus cases and up to 68% of deaths could have been prevented if a rotavirus vaccine were available as part of routine child-hood immunizations. Study of 35 case-control pairs indicated that severe illnesses, malnutrition, and care by traditional healers were risk factors for death. Rotavirus was found in 42% of samples from hospitalized children and was associated with severe disease and dehydration. CONCLUSIONS: The impact of the seasonal outbreaks of rotavirus disease could be diminished with a rotavirus vaccine, improvements in oral rehydration programs, and training of traditional healers in the proper management of children with acute diarrhea.OBJETIVOS: Se investigó un brote nacional de gastroenteritis grave por rotavirus en niños menores de 5 a

Rhetorikhandbücher geben zahlreiche Ratschläge, wie eine gute Festrede vorbereitet werden soll, um zu unterhalten, zu bewegen und zu belehren. Ziel dieser Untersuchung ist es festzustellen, welche Eigenschaften der Dankesrede die Zuhörer als erwünscht oder unerwünscht wahrnehmen und welche Charakteristika am meisten zur Qualität festlicher Dankesreden beitragen. Das Korpus der gesprochenen Texte bilden 30 Dankesreden anlässlich kroatischer Preisverleihungen in den Bereichen Schauspiel, Sport, Musik, Fernsehen, Literatur und Wirtschaft. Die Audio-Aufnahmen der Dankesreden wurden einer Gruppe von Hörern zur Bewertung in folgenden Kategorien vorgelegt: interessant, geistreich, hoher Sprachstil, feierlich, emotiv, persönlich, originell, bescheiden, vorbereitet und spontan. Zusätzlich wurde zu jeder Rede die offene Frage gestellt, was dem Zuhörer an der Rede gefallen oder nicht gefallen habe. Die Resultate der Perzeptionsanalye lassen erkennen, dass die Interessantheit einer Rede mit der Eigenschaft des Geistreichen, des Originellen, des Emotionalen und des Persönlichen in Verbindung gebracht wird und die Eigenschaft des Festlichen im Wesentlichen nur mit dem hohen Sprachstil und der Vorbereitetheit des Textes korreliert. Einige Eigenschaften können sowohl erwünscht als auch unerwünscht sein, z. B. Dialekt, Persönliches und Kürze. Die besten Dankesreden haben Eigenschaften, die im Grunde schwer miteinander zu verbinden sind: Einerseits soll der Text vorbereitet sein (hoher Stil, Wortwahl, Figuren, Originalität der Geschichte, Humor, andererseits wird bei der Ausführung Spontaneität (Aufrichtigkeit, Emotionalität, Persönlichkeit erwartet.

    Full Text Available While healthcare costs for rotavirus gastroenteritis requiring hospitalization may be burdensome on households in Malaysia, exploration on the distribution and catastrophic impact of these expenses on households are lacking.We assessed the economic burden, levels and distribution of catastrophic healthcare expenditure, the poverty impact on households and inequities related to healthcare payments for acute gastroenteritis requiring hospitalization in Malaysia.A two-year prospective, hospital-based study was conducted from 2008 to 2010 in an urban (Kuala Lumpur and rural (Kuala Terengganu setting in Malaysia. All children under the age of 5 years admitted for acute gastroenteritis were included. Patients were screened for rotavirus and information on healthcare expenditure was obtained.Of the 658 stool samples collected at both centers, 248 (38% were positive for rotavirus. Direct and indirect costs incurred were significantly higher in Kuala Lumpur compared with Kuala Terengganu (US$222 Vs. US$45; p<0.001. The mean direct and indirect costs for rotavirus gastroenteritis consisted 20% of monthly household income in Kuala Lumpur, as compared with only 5% in Kuala Terengganu. Direct medical costs paid out-of-pocket caused 141 (33% households in Kuala Lumpur to experience catastrophic expenditure and 11 (3% households to incur poverty. However in Kuala Terengganu, only one household (0.5% experienced catastrophic healthcare expenditure and none were impoverished. The lowest income quintile in Kuala Lumpur was more likely to experience catastrophic payments compared to the highest quintile (87% vs 8%. The concentration index for out-of-pocket healthcare payments was closer to zero at Kuala Lumpur (0.03 than at Kuala Terengganu (0.24.While urban households were wealthier, healthcare expenditure due to gastroenteritis had more catastrophic and poverty impact on the urban poor. Universal rotavirus vaccination would reduce both disease burden and health

    Background Rotavirus vaccines were introduced in Japan in November 2011. We evaluated the subsequent reduction of the health-care burden of rotavirus gastroenteritis. Methods We conducted active surveillance for rotavirus gastroenteritis among children under 5 years old before and after the vaccine introduction. We surveyed hospitalization rates for rotavirus gastroenteritis in children in Tsu City, Mie Prefecture, Japan, from 2007 to 2015 and surveyed the number of outpatient visits at a Tsu City clinic from 2010 to 2015. Stool samples were obtained for rotavirus testing and genotype investigation. We assessed rotavirus vaccine coverage for infants living in Tsu City. Results In the pre-vaccine years (2007–2011), hospitalization rates for rotavirus gastroenteritis in children under 5 years old were 5.5, 4.3, 3.1 and 3.9 cases per 1000 person-years, respectively. In the post-vaccine years (2011–2015), the rates were 3.0, 3.5, 0.8 and 0.6 cases per 1000 person-years, respectively. The hospitalization rate decreased significantly in the 2013–2014 and 2014–2015 seasons compared to the average of the seasons before vaccine introduction (P rotavirus infection was 66. In the post-vaccine years (2011–2015), the numbers for each season was 23, 23, 7 and 5, respectively. The most dominant rotavirus genotype shifted from G3P[8] to G1P[8] and to G2P[4]. The coverage of one dose of rotavirus vaccine in Tsu City was 56.5% in 2014. Conclusion After the vaccine introduction, the hospitalization rates and outpatient visits for rotavirus gastroenteritis greatly decreased. PMID:28246579

    Dysphagia is a common symptom in clinical practice. Due to the broad spectrum of underlying diseases many disciplines are involved in the therapy and diagnosis of dysphagia, where radiology plays a central role. The radiologist is confronted with different diagnostic problems and has to choose the most appropriate type of investigation. In many cases no organic disorder can be demonstrated by clinical examination, endoscopy or conventional radiological techniques. In this setting cineradiography is an outstanding tool for finding functional or structural changes in the swallowing chain. This study underlines the efficiency of cineradiography in the diagnosis of dysphagia. (orig.) [Deutsch] Die Dysphagie ist in der klinischen Praxis ein haeufiges Symptom. Aufgrund des weiten Spektrums zugrundeliegender Erkrankungen sind zahlreiche Fachdisziplinen mit der Diagnostik und Therapie der Dysphagie befasst, wobei der Roentgendiagnostik eine zentrale Rolle zukommt. Der Radiologe wird mit unterschiedlichen Fragestellungen konfrontiert und muss die geeignete Untersuchungsstrategie festlegen. Haeufig ist durch klinische Untersuchung, Endoskopie und konventionelle Roentgenuntersuchung keine organische Erkrankung nachweisbar. Mit der Hochfrequenzkinematographie steht dann ein Verfahren zur Verfuegung, welches in hervorragender Weise funktionelle und strukturelle Veraenderungen der am Schluckakt beteiligten Organe aufzeigen kann. Die hohe Effizienz der Methode wird in dieser Studie belegt. (orig.)

    2016-12-01

    Der übermäßige oder unkritische weltweite Einsatz von Antibiotika in der Medizin hat die Ausbreitung von Antibiotikaresistenzen beschleunigt. In einigen Bereichen sind viele Antibiotika bei bakteriellen Infektionen, die zuvor noch gut auf antibakterielle Wirkstoffe reagierten, mittlerweile wirkungslos geworden. Dermatologen/Venerologen setzten orale und topische Antibiotika bei der Behandlung von Acne vulgaris routinemäßig ein, obwohl Akne weder eine infektiöse Erkrankung ist noch alleine durch das Propionibacterium getriggert wird. Vielmehr ist sie eine komplexe, chronische entzündliche Hauterkrankung, die durch verschiedene pathogenetische Faktoren wie follikuläre Hyperkeratose, erhöhter Sebumproduktion, bakterielle Proliferation und Entzündung zustande kommt. Folglich sollte eine erfolgreiche Therapie auf die Bekämpfung verschiedener pathogenetischer Faktoren und nicht nur auf die von Propionibacterium acnes abzielen. Daher wurden topische Retinoide und Benzoylperoxid als Mittel der ersten Wahl definiert. Monotherapien mit lokalen Antibiotika sollten insgesamt vermieden werden. Systemische Antibiotika der Tetrazyklin-Gruppe haben bei bestimmen Krankheitsstadien ihren Sinn, ihre Wirkung könnte aber eher auf der antientzündlichen als auf der antibiotischen Reaktion beruhen. Gesundheitsbehörden ermahnen alle Gesundheitsdienstleister, den Einsatz von Antibiotika einzuschränken. Das Nutzen-Risiko-Verhältnis muss bei der Entscheidung für oder gegen eine antibiotische Therapie bei einem einzelnen Patienten immer auch in Bezug auf das öffentliche Interesse am Erhalt der Wirksamkeit von Antibiotika abgewogen werden. Im Folgenden werden das aktuelle Krankheitskonzept zu Acne vulgaris und die sich daraus ableitenden Konsequenzen für den Einsatz von Antibiotika vorgestellt. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

    Sebulke, Johannes

    In der Fördertechnik wird kaum ein größerer Einsatzfall so dem anderen gleichen, dass man zwei Anlagen nach denselben Zeichnungen fertigen kann. Konstruktionszeiten, Rüst- und Umstellungszeiten der Fertigung sind hoch; der Kunde muss bei Einzelanfertigung lange Lieferzeiten in Kauf nehmen. In der Fördertechnik haben sich daher Baukastenprinzip, Standardisierung und die Konstruktion von Erzeugnisreihen weitgehend durchgesetzt.

    Full Text Available Einnässen ist das häufigste urologische Symptom im Kindesalter. Es ist für den behandelnden Arzt eine Herausforderung, da der Erfolg oder Mißerfolg der eingeleiteten Therapie das psychische und auch das körperliche Wohlergehen des Kindes deutlich beeinflußt. Die Abklärung inkontinenter Kinder, die zumeist primär in der Hand von Pädiatern liegt, wird von den beteiligten Fachdisziplinen sehr unterschiedlich gehandhabt. Dabei zeichnet sich zumindest in Deutschland eine Tendenz zur primären Psychologisierung des Problems Enuresis ab. In unserer Spezialsprechstunde finden sich immer mehr Kinder, die beim Kinderpsychologen vorgestellt wurden, nachdem primäre medikamentöse Therapieversuche nicht erfolgreich waren. Auch eine Komedikation mit Ritalin wegen Aufmerksamkeits-Defizitsyndrom findet sich zunehmend. Die Diagnostik der vorbehandelnden Kollegen reicht dabei vom Nichtstun bis hin zu invasiven radiologischen Maßnahmen und endoskopischen Verfahren. Ein definierter Behandlungserfolg kann nur dann erzielt werden, wenn durch die vorangegangene Diagnostik eine klare Unterscheidung zwischen Enuresis und allen anderen Formen der Blasenstörung, zusammengefaßt im Begriff "Kindliche Harninkontinenz", getroffen wird. Nach den Leitlinien der deutschen Gesellschaft für Urologie (DGU und des Arbeitskreises "Urologische Funktionsdiagnostik und Urologie der Frau" muß man streng bei unterschiedlicher Ätiologie und Pathophysiologie zwischen Enuresis und kindlicher Harninkontinenz unterscheiden [1]. Die nicht-invasive Basisdiagnostik erlaubt in den meisten Fällen bereits die Klassifizierung der Störung und gibt Hinweise auf die Ursache. Die exakte pathophysiologische Abklärung bei kindlicher Inkontinenz kann aber nur durch weiterführende invasive Diagnostik bzw. mit Hilfe der (Video- Zystomanometrie erfolgen.

    2015-01-01

    Der Ausstieg aus der Nutzung der Kernenergie in Deutschland wurde im Sommer 2011 im Eiltempo beschlossen. Jetzt zeigt sich, dass es keinen realistischen Plan für den Umbau der Energieversorgung in der vorgesehenen Frist von zehn Jahren gibt. Für die Umstellung unserer gesamten Stromversorgung und damit unserer Wirtschaft ist der Zeitraum zu kurz. Es fehlt eine belastbare empirische Begründung, die Fragen der Versorgungssicherheit, der Finanzierbarkeit, der Auswirkungen auf die wirtschaftliche Entwicklung und die soziale Gerechtigkeit behandeln müsste. Somit droht diese Wende an ihren Widersprüchen zu scheitern. Konrad Kleinknecht versucht in seinem Buch, die Probleme zu benennen und Antworten zu finden. Für ihn stellen sich die folgenden Fragen: Welche Möglichkeit haben wir, mit Windkraft und Solarenergie einen Teil der Stromversorgung zu ersetzen? Welche Stromquellen bieten gesicherte Leistung? Können wir auf Kohlekraftwerke verzichten? Brauchen wir neue Stromtrassen? Wie lässt sich Strom speichern?...

    Ens, Konstantin; Wenzel, Fabian; Fischer, Bernd

    Die lokale Symmetrie von Hirnscans entlang der Sagittalebene zu ermitteln und zu modizifieren, ist für eine Reihe neurologischer Anwendungen interessant. Beispielsweise kann der voxelweise Vergleich von rechter und linker Hirnhälfte nur dann Aufschluss über die Lokalisierung von Läsionen geben, wenn durch Transformation ein Hirnscan eine möglichst hohe Symmetrie aufweist. Ein weiteres Anwendungsgebiet ist die Visualisierung von medialen Hirnschnitten, für die die Trennfläche beider Hirnhälfte möglichst eben sein sollte. Diese Arbeit stellt die Entwicklung eines Verfahrens vor, mit dessen Hilfe die Symmetrie von Hirnaufnahmen entlang der Sagittalebene verbessert werden kann. Dies geschieht unter Verwendung von aktiven Konturen, die mit Hilfe einer neuartigen Kostenfunktion gesteuert werden. Experimente am Ende der Arbeit mit strukturellen Kernspinaufnahmen demonstrieren die Leistungsfähigkeit des Verfahrens.

    Full Text Available In präklinischen Studien wurden Sicherheit und Durchführbarkeit von durch transurethralen Ultraschall geführten Injektionen von autologen Myo- und Fibroblasten zur Behandlung der Stressinkontinenz untersucht. Zwischen 2002 und März 2005 wurden 129 inkontinente Patienten (Alter 36–85 Jahre, 92 Frauen, 37 Männer in eine klinische Studie aufgenommen, um zu untersuchen, ob die Stressinkontinenz effektiv mittels durch transurethralen Ultraschall geführte Injektionen von autologen Myo- und Fibroblasten behandelt werden kann. Die Patienten litten an Stress- oder gemischter Harninkontinenz. Vor und nach der Therapie wurden ein definierter Inkontinenz-Score, Veränderungen der Lebensqualität sowie Morphologie und Funktion von Urethra und Rhabdosphinkter bewertet. Der transurethrale Ultraschall wurde zur Untersuchung und Visualisierung des unteren Harntraktes verwendet. Zusätzlich wurden vor und nach der Behandlung urodynamische und Labortests durchgeführt. Es wurden kleine Muskelbiopsien am Oberarm unter Lokalanästhesie entnommen und die Zellen in einem GMP-Labor zum Wachstum gebracht. Die Fibroblasten wurden fallweise mit einer kleinen Menge an Kollagen als Trägermaterial (ca. 2,5 ml gemischt. Mittels transurethralem Ultraschall und einer speziell entwickelten Injektionsvorrichtung wurden die Fibroblasten in die urethrale Mukosa zur Atrophiebehandlung injiziert. Die Myoblasten wurden direkt in den Rabdosphinkter zur Muskelrekonstruktion injiziert. Bei 108 Patienten konnte die Harninkontinenz nach der Injektion geheilt werden. Die postoperative Lebensqualität sowie die Dicke von Urethra und Rhabdosphinkter und die Aktivität und Kontraktilität des Rhabdosphinkter waren nach der Behandlung wesentlich verbessert. Bei 21 Patienten kam es zu einer Verbesserung der Harninkontinenz. Es traten keine Nebenwirkungen oder Komplikationen auf.

    2015-08-01

    Introduction In late October of 2012, Hurricane Sandy struck the northeast United States and shelters were established throughout the impacted region. Numerous cases of infectious viral gastroenteritis occurred in several of these shelters. Such outbreaks are common and have been well described in the past. Early monitoring for, and recognition of, the outbreak allowed for implementation of aggressive infection control measures. However, these measures required intensive medical response team involvement. Little is known about how such outbreaks affect the medical teams responding to the incident. Hypothesis/Problem Describe the impact of an infectious viral gastroenteritis outbreak within a single shelter on a responding medical team. The number of individuals staying in the single shelter each night (as determined by shelter staff) and the number of patients treated for symptoms of viral gastroenteritis were recorded each day. On return from deployment, members of a single responding medical team were surveyed to determine how many team members became ill during, or immediately following, their deployment. The shelter population peaked on November 5, 2012 with 811 individuals sleeping in the shelter. The first patients presented to the shelter clinic with symptoms of viral gastroenteritis on November 4, 2012, and the last case was seen on November 21, 2012. A total of 64 patients were treated for nausea, vomiting, or diarrhea over the 17-day period. A post-deployment survey was sent to 66 deployed medical team members and 45 completed the survey. Twelve (26.7%) of the team members who responded to the survey experienced symptoms of probable viral gastroenteritis. Team members reported onset of symptoms during deployment as well as after returning home. Symptoms started on days 4-8, 8-14, on the trip home, and after returning home in four, four, two, and two team members, respectively. Medical teams providing shelter care during viral gastroenteritis outbreaks are

  12. Der evolutionäre Naturalismus in der Ethik

    Science.gov (United States)

    Kaiser, Marie I.

    Charles Darwin hat eindrucksvoll gezeigt, dass der Mensch ebenso wie alle anderen Lebewesen ein Produkt der biologischen Evolution ist. Die sich an Darwin anschließende Forschung hat außerdem plausibel gemacht, dass sich nicht nur viele der körperlichen Merkmale des Menschen, sondern auch (zumindest einige) seiner Verhaltensdispositionen in adaptiven Selektionsprozessen herausgebildet haben. Die Vorstellung, dass auch die menschliche Moralität evolutionär bedingt ist, scheint daher auf den ersten Blick ganz überzeugend. Schließlich hat die Evolutionstheorie in den vergangenen Jahrzehnten in vielen Bereichen (auch außerhalb der Biologie) ihre weitreichende Bedeutung unter Beweis gestellt. Warum sollte, so könnte man beispielsweise fragen, gerade die Fähigkeit des Menschen, moralische Normen aufzustellen und gemäß ihnen zu handeln, nicht evolutionär erklärt werden können? Und warum sollte eine solche evolutionäre Erklärung der menschlichen Moralität irrelevant für die Rechtfertigung moralischer Normen sein? Warum sollte die Ethik eine Bastion der Philosophen bleiben, für die evolutionsbiologische Forschungsergebnisse über den Menschen und seine nächsten Verwandten keinerlei Relevanz besitzen?

    International Nuclear Information System (INIS)

    Bradford, J.; Wilson, L.; Thon, S.; Millar, N.

    2005-01-01

    This session on transmission issues focused on the role that transmission plays in electricity markets and the importance of getting the market structure right in terms of generation divestiture with buy back contracts, demand side responsive programs, transmission upgrades and long term contracts. The difficulties of distinguishing between market power and scarcity were examined along with some of the complications that ensue if transmission experiences congestion, as exemplified by the August 2003 blackout in eastern North America. The presentations described the best ways to handle transmission issues, and debated whether transmission should be deregulated or follow market forces. Issues of interconnections and reliability of connections were also debated along with the attempt to integrate renewables into the grid. Some presentations identified what new transmission must be built and what must be done to ensure that transmission gets built. The challenges and business opportunities for transmission in Alberta were discussed with reference to plans to invest in new infrastructure, where it is going outside of the province and how it works with other jurisdictions. Manitoba's Conawapa Hydro Project and its 2000 MW tie line to Ontario was also discussed. Some examples of non-optimal use of interconnections in Europe were also discussed in an effort to learn from these mistakes and avoid them in Canada. tabs., figs

    2001-06-01

    Our aim was to evaluate the efficacy of a prototype "YO-YO"-shaped covered stent for keeping experimental magnetic compression gastroenteric fistulas patent for 6 months. Magnets were introduced perorally with endoscopic and fluoroscopic guidance and were mated across the gastric and jejunal walls of 5 dogs. After a mean of 5.5 days a 12-mm diameter YO-YO stent was placed perorally in the resulting fistula. The gastroenteric anastomosis (GEA) with stent was observed endoscopically and gastrographically at 1- to 2-month intervals. There was no morbidity and there were no significant weight changes. The GEA was widely patent at necropsy at 6 months (n = 4); partial membrane separation occurred at 5 months in the fifth dog. There was minor breakage of the stent prongs in 2 animals. Peroral creation of a stented magnetic compression GEA is safe and provides long-term patency. This technique may be potentially useful for managing gastric outlet obstruction caused by malignancy.

    This study describes the epidemiology and circulating strains of sapovirus associated with gastroenteritis outbreaks in Alberta, Canada, from 2004 to 2007. Sapovirus was an important cause of gastroenteritis outbreaks, accounting for 43 (17.6%) of 244 outbreaks in which all samples tested were negative for norovirus. All 4 human sapovirus genotypes, GI, GII, GIV, and GV, were found in samples during these outbreaks. The greatest amount of sapovirus-associated outbreak activity occurred in 2007, after the emergence of genotype GIV in December 2006. The majority of sapovirus-associated outbreaks in Alberta during this period (27 [62.8%] of 43) occurred in hospitals, community long-term care facilities, and senior lodges. Adults>65 years of age were the age group most commonly affected.

    Visceral hypersensitivity and abnormal coping are common in children with functional abdominal pain disorders (FAPDs). Thus, it would be expected that children with visceral hypersensitivity would report more pain if their gut is acutely inflamed. The aim of the study was to compare clinical symptoms and somatization of children with and without FAPDs at time of an episode of acute gastroenteritis. Seventy children with acute gastroenteritis and their parents completed the Rome III Diagnostic Questionnaire for Pediatric Functional GI Disorders and the Children's Somatization Inventory. Twenty-one percent of children were diagnosed with an FAPD. Children with FAPDs showed significantly more nongastrointestinal somatic symptoms than children without FAPDs. There were no significant differences in abdominal pain, nausea, vomiting, or school absenteeism between both groups at time of consultation.

Hereby we present the case of a 29-year-old male without history of allergies who was evaluated for unspecific gastrointestinal symptoms, without relevant findings on physical examination and presenting an initial complete blood count (CBC with severe eosinophilia. The patient was evaluated and the diagnosis of eosinophilic gastroenteritis was confirmed by histopathological findings. The relevance of the case resides in highlighting the lack of guidelines or consensus for histological diagnosis being virtually the only one available. To a similar extent, treatment evidence is based on case series with a reasonable number of patients and case reports.

    This study evaluates potential markers in blood and stools for their ability to distinguish bacterial from viral gastroenteritis. A total of 108 patients were prospectively recruited, of which 27 showed bacterial, 30 viral, and 51 no detectable pathogen, respectively. Cytokines, C-reactive protein (CRP), and white blood cells as well as the 2 fecal markers lactoferrin and calprotectin were determined. Statistics comprised Kruskal-Wallis test and U test in addition to an assessment of receiver operating characteristic. Interferon γ (IFNγ) levels were significantly increased in the viral group compared to the bacterial and nonspecific group. For the bacterial group, both fecal markers lactoferrin and calprotectin as well as CRP were significantly higher in comparison to the other 2 groups. To differentiate between bacterial and viral gastroenteritis, CRP, serum IFNγ, and the fecal proteins lactoferrin and calprotectin may be useful. A corresponding algorithm should be evaluated prospectively. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available In vorausgegangenen Studien konnte gezeigt werden, dass eine Gesichtsklassifikation mittels Gesichtsphotographien zur Diagnostik von Akromegalie mit guten Ergebnissen eingesetzt werden kann. In diesem Artikel werden die grundlegende Vorgehensweise der Klassifikation mittels der Software FIDA erläutert sowie Optimierungsansätze mit dem Ziel diskutiert, diese Methode näher an den klinischen Einsatz zu bringen. Die Gesichtsklassifikation basiert auf „Knotenpunkten“, die verteilt über die jeweilige Frontal- und/oder Seitenansicht des Gesichts platziert werden und den so genannten „Graphen“ bilden. Mittels mathematischer Verfahren erfolgt eine Analyse der zugrunde liegenden Textur des Bildes sowie die Auswertung geometrischer Informationen. Untersucht wird, wie sich die Reduktion von als irrelevant eingestuften Knoten auf das Klassifikationsergebnis auswirkt. Ebenso wird untersucht, wie sich neu definierte Knoten, die die typischen morphologischen Veränderungen der akromegalen Erkrankung im Gesicht berücksichtigen, auf die Klassifizierungsergebnisse auswirken. Die interne Validierung erfolgt an einem Datenset bestehend aus 57 an Akromegalie erkrankten Probanden (29 weiblich, 28 männlich sowie 59 Kontrollen (29 weiblich, 30 männlich. Die externe Validierung wird an einer weiteren Stichprobe gemessen, die zum Zeitpunkt der Präsentation auf der Tagung der European Neuroendocrine Association 2012 in Wien 13 akromegale Patienten (7 weiblich, 6 männlich sowie 45 Kontrollen (25 weiblich, 20 männlich umfasste. Die Datenbank wird ständig durch neue Probanden aus verschiedenen Quellen erweitert. Erste Ergebnisse zeigen, dass die Verwendung von Graphen mit reduzierten Knoten und von neuen Sets von Knoten unter Einbeziehung typischer morphologischer Veränderungen des Gesichts die Klassifizierung weiter verbessert.

    2013-10-01

    In inverse scattering theory, transmission eigenvalues can be seen as the extension of the notion of resonant frequencies for impenetrable objects to the case of penetrable dielectrics. The transmission eigenvalue problem is a relatively late arrival to the spectral theory of partial differential equations. Its first appearance was in 1986 in a paper by Kirsch who was investigating the denseness of far-field patterns for scattering solutions of the Helmholtz equation or, in more modern terminology, the injectivity of the far-field operator [1]. The paper of Kirsch was soon followed by a more systematic study by Colton and Monk in the context of developing the dual space method for solving the inverse scattering problem for acoustic waves in an inhomogeneous medium [2]. In this paper they showed that for a spherically stratified media transmission eigenvalues existed and formed a discrete set. Numerical examples were also given showing that in principle transmission eigenvalues could be determined from the far-field data. This first period of interest in transmission eigenvalues was concluded with papers by Colton et al in 1989 [3] and Rynne and Sleeman in 1991 [4] showing that for an inhomogeneous medium (not necessarily spherically stratified) transmission eigenvalues, if they existed, formed a discrete set. For the next seventeen years transmission eigenvalues were ignored. This was mainly due to the fact that, with the introduction of various sampling methods to determine the shape of an inhomogeneous medium from far-field data, transmission eigenvalues were something to be avoided and hence the fact that transmission eigenvalues formed at most a discrete set was deemed to be sufficient. In addition, questions related to the existence of transmission eigenvalues or the structure of associated eigenvectors were recognized as being particularly difficult due to the nonlinearity of the eigenvalue problem and the special structure of the associated transmission

    Rapid intravenous (IV) rehydration is commonly used for the management of pediatric gastroenteritis in the emergency department. The current practice shows wide variation in the volume and rate of rapid IV hydration. The aim of this review was to assess the efficacy of rapid IV rehydration compared with standard method in children with gastroenteritis. MEDLINE (1946-2014), EMBASE (1974-2014), and CENTRAL via the Cochrane Library (Issue 8, 2014) were systematically searched to identify eligible studies. Inclusion criteria were randomized controlled trials of rapid IV rehydration in children with gastroenteritis. A total of 1513 articles were retrieved, and our inclusion criteria were met by 3 studies, with a total of 464 participants. The percentage of children who were successfully rehydrated and tolerated oral fluids at 2 to 4 hours after starting IV fluid therapy ranged from 69% to 100% in both rapid IV rehydration and standard method. Time to discharge ranged from 2 to 6 hours (rapid rehydration) versus 2 to 5 hours (standard rehydration). Emergency department revisits ranged from 3% to 16% (rapid rehydration) versus 5% to 14% (standard). Summarized results suggested that rapid IV rehydration may be associated with longer time-to-discharge and higher readmission rates. The new evidence fails to demonstrate superiority of large-volume (60 mL/kg/h) over standard (20 mL/kg/h) IV rehydration. Standard volume IV rehydration for 1 to 4 hours followed by oral hydration or maintenance IV fluids seems sufficient for most children with gastroenteritis requiring IV fluid administration. However, more evidence is needed to establish an optimal IV rehydration regimen.

    Prospectively identifying children with significant dehydration from gastroenteritis is difficult in acute care settings. Previous work by our group has shown that bedside ultrasound (US) measurement of the inferior vena cava (IVC) and the aorta (Ao) diameter ratio is correlated with intravascular volume. This study was designed to validate the use of this method in the prospective identification of children with dehydration by investigating whether the IVC/Ao ratio correlated with dehydration in children with acute gastroenteritis. Another objective was to investigate the interrater reliability of the IVC/Ao measurements. A prospective observational study was carried out in a pediatric emergency department (PED) between November 2007 and June 2009. Children with acute gastroenteritis were enrolled as subjects. A pair of investigators obtained transverse images of the IVC and Ao using bedside US. The ratio of IVC and Ao diameters (IVC/Ao) was calculated. Subjects were asked to return after resolution of symptoms. The difference between the convalescent weight and ill weight was used to calculate the degree of dehydration. Greater than or equal to 5% difference was judged to be significant. Linear regression was performed with dehydration as the dependent variable and the IVC/Ao as the independent variable. Pearson's correlation coefficient was calculated to assess the degree of agreement between observers. A total of 112 subjects were enrolled. Seventy-one subjects (63%) completed follow-up. Twenty-eight subjects (39%) had significant dehydration. The linear regression model resulted in an R² value of 0.21 (p dehydration. Forty-eight paired measurements of IVC/Ao ratios were made. The Pearson correlation coefficient was 0.76.   In this pilot study the ratio of IVC to Ao diameters, as measured by bedside US, was a marginally accurate measurement of acute weight loss in children with dehydration from gastroenteritis. The technique demonstrated good interrater

    Children with gastroenteritis often develop dehydration with metabolic acidosis. Serum ketones are frequently elevated in this population. The goal was to determine the relationship between initial serum ketone concentration and both the degree of dehydration and the magnitude of acidosis. This was a secondary analysis of a prospective trial of crystalloid administration for rapid rehydration. Children 6 months to 6 years of age with gastroenteritis and dehydration were enrolled. A point-of-care serum ketone (beta-hydroxybutyrate) concentration was obtained at the time of study enrollment. The relationship between initial serum ketone concentration and a prospectively assigned and previously validated clinical dehydration score, and serum bicarbonate concentration, was analyzed. A total of 188 patients were enrolled. The median serum ketone concentration was elevated at 3.1 mmol/L (interquartile range [IQR] = 1.2 to 4.6 mmol/L), and the median dehydration score was consistent with moderate dehydration. A significant positive relationship was found between serum ketone concentration and the clinical dehydration score (Spearman's rho = 0.22, p = 0.003). Patients with moderate dehydration had a higher median serum ketone concentration than those with mild dehydration (3.6 mmol/L vs. 1.4 mmol/L, p = 0.007). Additionally, the serum ketone concentration was inversely correlated with serum bicarbonate concentration (ρ = -0.26, p Children with gastroenteritis and dehydration have elevated serum ketone concentrations that correlate with both degree of dehydration and magnitude of metabolic acidosis. Point-of-care serum ketone measurement may be a useful tool to inform management decisions at the point of triage or in the initial evaluation of children with gastroenteritis and dehydration. © 2013 by the Society for Academic Emergency Medicine.

    Recurrent cases of gastroenteritis occurred in a small hotel. The causative agent of disease could not be detected. The cause and the source of the disease were established through epidemiological investigations and laboratory diagnosis. The causative agent of the disease was norovirus GI.3. Norovirus GI was detected in the water from the well and on surfaces at the hotel. Both epidemiological investigations and laboratory diagnostics are needed in resolving epidemics. Continuous development of laboratory methods is important.

    The aim of this study was to conduct an investigation into an outbreak of waterborne disease caused by Norovirus due to the consumption of contaminated drinking water. The first week after the school summer holidays we detected an outbreak of gastroenteritis at a school in Borges Blanques (Lleida, Spain). A retrospective cohort study was carried out to investigate: water consumption and food (six items). We assessed RNA Norovirus by RT-PCR in 6 stool samples. The risk of gastroenteritis was assessed by applying adjusted risk ratio (RRa) analysis at 95% confidence intervals (CI). The overall attack rate was 45% (96/213). The main symptoms were: abdominal pain, 88.4% (84/95); nausea, 65.9% (62/94), and vomiting, 64.6% (62/96). The consumption of school drinking water was statistically associated with the disease (RRa: 2.8; 95% CI: 1.3-6.2). The school water tank was dirty, but this drinking water was qualified as potable. Six stool samples gave positive results for Norovirus. Norovirus caused this waterborne outbreak of gastroenteritis transmitted through treated drinking water. It should be obligatory to regularly clean school drinking water deposit tanks, especially after the summer holidays.

    Plesiomonas shigelloides is a common pathogen in tropical regions, whereas it is rarely isolated in temperate climates. It is most often found in surface water and fish. During the last 10 years it was found to cause gastroenteritis 6 times in Ludwigshafen. Not all of these patients reported a trip to foreign countries. A 54-year-old male patient was hospitalized after a trip to Malaysia with strong greenish watery diarrhea and chills. On physical examination we saw a dehydrated patient in severely reduced general condition. The stool frequency was 30/d. The laboratory examinations only showed elevated parameters of inflammation. Plesiomonas shigelloides was cultivated in the stool cultures. With appropriate substitution of fluid and electrolytes, and antidiarrheal therapy the patient resumed a normal diet without any complications. Three days later his bowel movements were normal and his general condition was greatly improved. We withheld antibiotic therapy because of the noncomplicated course of illness. In Germany infections with Plesiomonas shigelloides are rare, an increase is observed because of increasing tourism to tropical regions. The course of infection is sometimes asymptomatic, but usually patients develop an acute gastroenteritis. Especially immunocompromised patients can show serious courses of infection. Plesiomonas shigelloides should be included in the differential diagnosis of acute gastroenteritis after journeys to tropical regions. Some of our patients, however, denied traveling to tropical regions. They also denied consuming seafood, which indicates a risk of infection in Germany. Still an infection with Plesiomonas shigelloides seems to be rare in northern European countries.

    Full Text Available Adenoviruses are one of the most important etiological agents of serious gastroenteritis among infants and young children. Fecal specimens from patients with an acute gastroenteritis were evaluated for the presence of adenovirus (Ad40, 41 from April 2002 to February 2004. During the study, 1052 samples were collected from children under the age of 5 years in six educational and therapeutic pediatric centers. The specimens were tested for adenovirus (Ad40, 41 by EIA technique in the Virology Department of Pasteur Institute of Iran. Adenoviruses (Ad40, 41 were detected from 27(2.6% samples, but were not detected in 150 samples of healthy control group. In this study the highest rate of adenovirus was found in children aged 6 to 12 months (40.7%, but the male to female ratio inpatients was approximately equal. Adenovirus (Ad40, 41 infections peaked in the winter as 48.1% was detected from December to March. There were a statistically significant difference between age and infection (P < 0.001, also between season with adenovirus (Ad40, 41 infection (P = 0.005. Breast-feeding had a protective action against adenovirus (Ad40, 41 infection. This study revealed that enteric adenovirus (Ad40, 41 is an etiological agent of acute gastroenteritis among children in Tehran.

    Norovirus (NoV) is responsible for an estimated 90 % of all epidemic nonbacterial outbreaks of gastroenteritis worldwide. Waterborne outbreaks of NoV are commonly reported. A novel GII.17 NoV strain emerged as a major cause of gastroenteritis outbreaks in China during the winter of 2014/2015. During this time, an outbreak of gastroenteritis occurred at a hotel in a ski park in Hebei Province, China. Epidemiological investigations indicated that one water well, which had only recently been in use, was the probable source. GII.17 NoV was detected by real-time reverse-transcription polymerase chain reaction from samples taken from cases, from concentrated water samples from water well, and from the nearby sewage settling tank. Nucleotide sequences of NoV extracted from clinical and water specimens were genetically identical and had 99 % homology with Beijing/CHN/2015. All epidemiological data indicated that GII.17 NoV was responsible for this outbreak. This is the first reported laboratory-confirmed waterborne outbreak caused by GII.17 NoV genotype in China. Strengthening management of well drinking water and systematica monitoring of NoV is essential for preventing future outbreaks.

    Norovirus (NoV) gastroenteritis outbreaks appear frequently in food service operations (FSOs), such as in restaurants and canteens. In this study the presence of NoV and adenovirus (AdV) genomes was investigated on the surfaces of premises, especially in kitchens, of 30 FSOs where foodborne gastroenteritis outbreaks were suspected. The objective was to establish a possible association between the presence of virus genomes on surfaces and a visual hygienic status of the FSOs. NoV genome was found in 11 and AdV genome in 8 out of 30 FSOs. In total, 291 swabs were taken, of which 8.9% contained NoV and 5.8% AdV genome. The presence of NoV genomes on the surfaces was not found to associate with lower hygiene level of the premises when based on visual inspection; most (7/9) of the FSOs with NoV contamination on surfaces and a completed evaluation form had a good hygiene level (the best category). Restaurants had a significantly lower proportion of NoV-positive swabs compared to other FSOs (canteens, cafeteria, schools etc.) taken together (p = 0.00014). The presence of a designated break room for the workers was found to be significantly more common in AdV-negative kitchens (p = 0.046). Our findings suggest that swabbing is necessary for revealing viral contamination of surfaces and emphasis of hygiene inspections should be on the food handling procedures, and the education of food workers on virus transmission.

  6. Quantifying Transmission.

    Transmissibility is the defining characteristic of infectious diseases. Quantifying transmission matters for understanding infectious disease epidemiology and designing evidence-based disease control programs. Tracing individual transmission events can be achieved by epidemiological investigation coupled with pathogen typing or genome sequencing. Individual infectiousness can be estimated by measuring pathogen loads, but few studies have directly estimated the ability of infected hosts to transmit to uninfected hosts. Individuals' opportunities to transmit infection are dependent on behavioral and other risk factors relevant given the transmission route of the pathogen concerned. Transmission at the population level can be quantified through knowledge of risk factors in the population or phylogeographic analysis of pathogen sequence data. Mathematical model-based approaches require estimation of the per capita transmission rate and basic reproduction number, obtained by fitting models to case data and/or analysis of pathogen sequence data. Heterogeneities in infectiousness, contact behavior, and susceptibility can have substantial effects on the epidemiology of an infectious disease, so estimates of only mean values may be insufficient. For some pathogens, super-shedders (infected individuals who are highly infectious) and super-spreaders (individuals with more opportunities to transmit infection) may be important. Future work on quantifying transmission should involve integrated analyses of multiple data sources.

    Acute gastroenteritis remains a common condition among infants and children throughout the world. In 1996, The American Academy of Pediatrics (AAP) revised its recommendations for the treatment of infants and children with acute gastroenteritis. The purpose of this survey was to determine how closely current treatment among Lebanese pediatricians compares with the AAP recommendations and to determine the impact of such management on the healthcare system. The outline of the study was based on a telephone questionnaire that addressed the management of healthy infants and children below five years of age with acute gastroenteritis complicated by mild to moderate dehydration. In addition, the costs of medical treatment and requested laboratory studies were calculated. A total of 238 pediatricians completed the questionnaire. Most pediatricians prescribed Oral Rehydration Solutions (ORS) for rehydration (92.4%), advised breastfeeding during acute gastroenteritis (81.5%), and avoided parenteral rehydration for mild to moderate dehydration (89.1%). In addition to ORS, oral fluids such as soda, juices, and rice water were allowed for rehydration by 43.7% of pediatricians. Thirty-one percent of pediatricians delayed re-feeding for more than 6 hours after initiation of rehydration. Only 32.8% of pediatricians kept their patients on regular full-strength formulas, and only 21.8% permitted full-calorie meals for their patients. 75.4% of pediatricians did not order any laboratory studies in cases of mild dehydration and 50.4% did not order any laboratory studies for moderate dehydration. Stool analysis and culture were ordered by almost half of the pediatricians surveyed. Seventy-seven percent prescribed anti-emetics, 61% prescribed probiotics, 26.3% prescribed antibiotics systematically and local antiseptic agents, 16.9% prescribed zinc supplements, and 11% percent prescribed antidiarrheal agents. Pediatricians in Lebanon are aware of the importance of ORS and the positive

    Winkler, Reinhard

    Meist enden ähnliche Gespräche über Mathematik etwa an diesem Punkt, ohne dass der Nichtmathematiker von der Sinnhaftigkeit mathematischer Forschung, ja mathematischer Tätigkeit generell überzeugt werden konnte. Ich glaube nicht, dass dem Laien Blindheit für die Großartigkeit unserer Wissenschaft vorzuwerfen ist, wenn hier keine befriedigendere Kommunikation zustande kommt. Ich sehe als Ursache eher ein stark verkürztes Bild von der Mathematik, welches auch Fachleute oft zeichnen, weil ihnen eine angemessenere Darstellung ihres Faches zu viel Mühe macht - und das obwohl Mathematik nur betreiben kann, wer geistige Mühen sonst keineswegs scheut. Ich will versuchen, den Ursachen dieses eigentümlichen Phänomens auf den Grund zu gehen.

  9. Force transmissibility versus displacement transmissibility

    It is well-known that when a single-degree-of-freedom (sdof) system is excited by a continuous motion of the foundation, the force transmissibility, relating the force transmitted to the foundation to the applied force, equals the displacement transmissibility. Recent developments in the generalization of the transmissibility to multiple-degree-of-freedom (mdof) systems have shown that similar simple and direct relations between both types of transmissibility do not appear naturally from the definitions, as happens in the sdof case. In this paper, the authors present their studies on the conditions under which it is possible to establish a relation between force transmissibility and displacement transmissibility for mdof systems. As far as the authors are aware, such a relation is not currently found in the literature, which is justified by being based on recent developments in the transmissibility concept for mdof systems. Indeed, it does not appear naturally, but the authors observed that the needed link is present when the displacement transmissibility is obtained between the same coordinates where the applied and reaction forces are considered in the force transmissibility case; this implies that the boundary conditions are not exactly the same and instead follow some rules. This work presents a formal derivation of the explicit relation between the force and displacement transmissibilities for mdof systems, and discusses its potential and limitations. The authors show that it is possible to obtain the displacement transmissibility from measured forces, and the force transmissibility from measured displacements, opening new perspectives, for example, in the identification of applied or transmitted forces. With this novel relation, it becomes possible, for example, to estimate the force transmissibility matrix with the structure off its supports, in free boundary conditions, and without measuring the forces. As far as force identification is concerned, this

    In February 2009, an outbreak of 38 cases of gastroenteritis occurred among the participants of two Dutch coach trips (A and B) who visited the same hotel in Germany. We initiated an outbreak investigation to determine possible risk of food-borne infection. A retrospective cohort study was performed among 87 passengers using a self-administered questionnaire. The response rate was 75 of 87 (86%). Mean age was 65 years. Cases were defined as participants of the two coach trips who had diarrhoea and/or vomiting at least once within 24 hours in the period between 7 and 14 February 2009. We distinguished early and late cases, with symptoms starting within or after 72 hours of arrival in the hotel. Overall attack-rate was 38 of 75 (51%). Microbiological investigation was performed on stool samples of two passengers from Coach A and two passengers from Coach B. Identical norovirus genotype II.4 sequences were detected in all four samples. Univariate analysis revealed a potential risk for early cases from juice consumption , which was most clearly seen for Coach B on day of arrival (juice at lunch: relative risk (RR): 3.9, 95% confidence interval (CI): 1.3-11.7; juice at dinner: RR: 5.5, 95% CI: 1.6-18.1). A dose-response relationship was found. This outbreak was probably caused by using the taps of juice served in large containers with a tap for self-service, due to environmental contamination through person-to-person transmission. Still the role of either contaminated juice or contact with contaminated juice cannot be ruled out.

    There are many varieties of gastroenteritis viruses, of which norovirus (NoV) accounts for over 90% of the viral food poisoning incidents in Japan. However, protocols for rapidly identifying other gastroenteritis viruses need to be established to investigate NoV-negative cases intensively. In this study, a multiplex real-time PCR assay targeting rotavirus A, rotavirus C, sapovirus, astrovirus, adenovirus, and enterovirus was developed using stool samples collected from gastroenteritis patients between 2010 and 2013 in Fukui Prefecture, Japan. Of the 126 samples collected sporadically from pediatric patients with suspected infectious gastroenteritis, 51 were positive for non-NoV target viruses, whereas 27 were positive for NoV, showing a high prevalence of non-NoV viruses in pediatric patients. In contrast, testing in 382 samples of 58 gastroenteritis outbreaks showed that non-NoV viruses were detected in 13 samples, with NoV in 267. Of the 267 NoV-positive patients, only two were co-infected with non-NoV target viruses, suggesting that testing for non-NoV gastroenteritis viruses in NoV-positive samples was mostly unnecessary in outbreak investigations. Given these results, multiplex real-time PCR testing for non-NoV gastroenteritis viruses, conducted separately from NoV testing, may be helpful to deal with two types of epidemiological investigations, regular surveillance of infectious gastroenteritis and urgent testing when gastroenteritis outbreaks occur. © 2017 Wiley Periodicals, Inc.

    Full Text Available Die Überprüfung der Funktionstüchtigkeit der Ovarien ist für die Beratung und Planung einer IVF-Behandlung von besonderer Bedeutung. Die Funktionstüchtigkeit wird im Allgemeinen als ovarielle Reserve bezeichnet. Diese setzt sich aus der Anzahl der im Rahmen einer kontrollierten ovariellen Stimulation gewonnenen Eizellen und der Qualität eben dieser zusammen. Es gibt verschiedene Möglichkeiten, diese zu bestimmen, jedoch keinen Parameter, der beide Kriterien optimal erfüllt. Auch zeigen sich viele Parameter als nicht unabhängig voneinander oder als zu aufwendig für die routinemäßige Verwendung bei Frauen mit Kinderwunsch. Die Kombination einzelner Parameter erlaubt jedoch eine gute Aussage über die zu erwartende Antwort der Ovarien auf eine kontrollierte ovarielle Stimulation und somit die Anpassung der Stimulation.

Das verursachte in der Bukowina und besonders in ihrer Hauptstadt Czernowitz die Herausbildung einer deutschsprachigen Literatur, deren Anfänge in die Mitte des 19. Jahrhundert fallen. Zuerst nur als „Heimatliteratur“ begriffen, entwickelte sie sich bald, vor allem auf dem Gebiet der lyrischen Dichtung, zu einem beachtlichen literarischen Phänomen, das in der Zwischenkriegszeit im Werk solcher Dichter wie Alfred Margul-Sperber, Rose Ausländer, David Goldfeld, Alfred Kittner, Moses Rosenkranz, Immanuel Weißglas, Paul Celan, Alfred Gong, Selma Meerbaum-Eisinger ihre höchste Blüte erlebte. Infolge der fortschreitenden Romanisierung des Landes und der Bedrohung des Sprachverlusts greifen um diese Zeit viele Czernowitzer deutschjüdische Dichter öfters zur Sprachproblematik, indem sie sie in ihren Gedichten im tragischen Sinne thematisieren. Nach dem Holocaust und der Emigration aus der Bukowina verwandelt sich die Muttersprache für verbannte Dichter in ein Synonym der Heimat („Mutterland Wort“.

    2016-06-01

    This is a critical transcription of Paul Feyerabend's earliest extant essay "Der Begriff der Verständlichkeit in der modernen Physik" (1948) recovered from the European Forum Alpbach archives. In it, Feyerabend defends positivism as a progressive framework for scientific research in certain stages of scientific development. He argues that in physics visualizability (Anschaulichkeit) and intelligibility (Verständlichkeit) are time-conditioned concepts: what is deemed visualizable in the development of physical theories is relative to a specific historical context and changes over time. He concludes that from time to time the abandonment of visualizability is crucial for progress in physics, as it is conducive to major theory change, illustrating the point on the basis of advances in atomic theory.

Problems are insulation, radio interference and the cost of underground lines (16 times that of overhead lines). Also considered are the economics of the grid as a means of transporting energy and as a means of spreading the peak load over the power stations in the most efficient manner. Finally, the question of amenities is discussed.

    Paediatric acute gastroenteritis is a global public health problem. Comprehensive laboratory investigation for viral, bacterial and parasitic agents is helpful for improving management of acute gastroenteritis in health care settings and for monitoring and controlling the spread of these infections. Our study aimed to investigate the role of various pathogens in infantile diarrhoea in Bulgaria outside the classical winter epidemics of rotavirus and norovirus. Stool samples from 115 hospitalized children aged 0-3 years collected during summer months were tested for presence of 14 infectious agents - group A rotavirus, astrovirus, Giardia, Cryptosporidium and Entamoeba using ELISAs; norovirus by real-time RT-PCR; picobirnavirus and sapovirus by RT-PCR; adenovirus using PCR, and Salmonella, Shigella, Escherichia coli, Yersinia and Campylobacter using standard bacterial cultures. Infectious origin was established in a total of 92 cases and 23 samples remained negative. A single pathogen was found in 67 stools, of which rotaviruses were the most prevalent (56.7 %), followed by noroviruses (19.4 %), enteric adenoviruses (7.5 %), astroviruses (6.0 %), bacteria and parasites (4.5 % each) and sapoviruses (1.4 %). Rotavirus predominant genotypes were G4P[8] (46.3 %) and G2P[4] (21.4 %); for astroviruses, type 1a was the most common, while the GII.4/2006b variant was the most prevalent among noroviruses. Bacteria were observed in five cases, with Salmonella sp. as the most prevalent, while parasites were found in ten stool samples, with Giardia intestinalis in five cases. The results demonstrated high morbidity associated with viral infections and that rotavirus and norovirus remain the most common pathogens associated with severe gastroenteritis during summer months in Bulgaria, a country with a temperate climate, and significant molecular diversity among circulating virus strains. © 2015 The Authors.

    Rotavirus is the leading cause of acute gastroenteritis (AGE) and the most frequent cause of severe diarrhoea in children aged less than 5 years. Although the epidemiology of rotavirus gastroenteritis (RVGE) is well documented, there are few data on the impact of RVGE on the families of affected children. Data associated with the burden of RVGE, including number of working days lost, levels of parental stress, the need for alternative childcare arrangements and additional nappies used, were extracted from questionnaires completed by parents of children participating in a prospective, multicentre, observational study (Rotavirus gastroenteritis Epidemiology and Viral types in Europe Accounting for Losses in public health and society, REVEAL), conducted during 2004-2005 in selected areas of Belgium, France, Germany, Italy, Spain, Sweden, and the United Kingdom to estimate the incidence of RVGE in children aged less than 5 years seeking medical care as a result of AGE. 1102 children with RVGE were included in the present analysis. The proportion of RVGE cases that required at least one parent or other person to be absent from work was 39%-91% in the hospital setting, 44%-64% in the emergency department, and 20%-64% in primary care. Self-reported levels of parental stress were generally high (mean stress levels, > or = 5 on a 10-point visual analogue scale). Additional childcare arrangements were required in up to 21% of RVGE episodes. The mean number of nappies used per day during RVGE episodes was approximately double that used when the child was not ill. Paediatric RVGE cases cause disruption to families and parental stress. The burden of RVGE on children and their families could be substantially reduced by routine rotavirus vaccination of infants.

    To identify the source of infection and risk factors and to provide control measures regarding an outbreak of gastroenteritis involving 30 villagers. Who attended the same wedding party held on March 5(th), 2012, a survey was carried out. Case was defined as having onset of vomiting, nausea, stomachache or diarrhea among the attendees of a wedding party. We randomly selected and interviewed 140 from 470 attendees on their symptoms and food exposures at the wedding. We compared food-specific attack rates (AR) for gastroenteritis in a retrospective cohort study. The leftover foods were tested for Salmonella, Shigella, and Staphylococcus aureus. The leftover Boletus mushrooms were examined and species determined by the Kunming Institute of Botany, Chinese Academy of Sciences. Of the 140 attendees 61% (85) developed gastroenteritis. Case-attendees had vomiting (94%), nausea (89%), stomachache (53%), and diarrhea (51%). The AR among attendees who ate Boletus mushroom was 69% (81/118), compared to 18% (4/22) of those who did not (RR = 3.8, 95%CI: 1.5 - 9.2). When comparing the ARs between the attendees on consumption of other foods, data did not show statistically significant differences. Among the 7 species of Boletus identified from the leftover mushrooms, 3 (B. venenatus, B. sinicus and B. magnificus) were toxic. Store keepers bought dried or fresh mushrooms from local villagers who had picked up them from the mountains. Salmonella, Shigella, and Staphylococcus aureus tests on those leftover food showed negative results. Poisonous Boletus mushroom contributed to this outbreak. We recommended that education should be targeted on mushroom-pickers regarding how to recognize the poisonous mushrooms. Regulations and laws should also be developed to facilitate the necessary process.

    We previously created a clinical dehydration scale. Our objective was to validate the clinical dehydration scale with a new cohort of patients with acute gastroenteritis who were assessed in a tertiary emergency department in a developed country. A prospective observational study was performed in an emergency department at a large pediatric tertiary center in Canada. Children 1 month to 5 years of age with symptoms of acute gastroenteritis who were assessed in the emergency department were enrolled consecutively during a 4-month period. The main outcome measures were length of stay, proportion of children receiving intravenous fluid rehydration, and proportions of children with abnormal serum pH values or bicarbonate levels. A total of 205 children were enrolled, with a mean age of 22.4 +/- 14.9 months; 103 (50%) were male. The distribution of severity categories was as follows: no dehydration (score of 0), n = 117 (57%); some dehydration (score of 1-4), n = 83 (41%); moderate/severe dehydration (score of 5-8), n = 5 (2%). The 3 dehydration categories were significantly different with respect to the validation hypotheses (length of stay, mean +/- SD: none, 245 +/- 181 minutes; some, 397 +/- 302 minutes; moderate/severe, 501 +/- 389 minutes; treatment with intravenous fluids: none, n =17, 15%; some, n = 41, 49%; moderate/severe, n = 4, 80%; number of vomiting episodes in the 7 days before the emergency department visit: none, 8.4 +/- 7.7 episodes; some, 13 +/- 10.7 episodes; moderate/severe, 30.2 +/- 14.8 episodes). The clinical dehydration scale and the 3 severity categories were valid for a prospectively enrolled cohort of patients who were assessed in our tertiary emergency department. The scoring system was valuable in predicting a longer length of stay and the need for intravenous fluid rehydration for children with symptoms of acute gastroenteritis.

    Full Text Available Fundamento: Los brotes de gastroenteritis aguda de origen vírico son actualmente uno de los problemas de salud que más están afectando a las personas residentes en instituciones de la tercera edad. El objetivo del estudio es investigar las causas del origen y transmisión de un brote de gastroenteritis aguda por virus Norwal-Like. Método: En una residencia de ancianos con 141 residentes y 71 trabajadores expuestos, se investigó la relación entre un brote de gastroenteritis aguda y distintas variables: características personales, de lugar, fecha de inicio de los síntomas, clínica de la enfermedad y factores causales (alimentos y agua de consumo. Se realizó un estudio descriptivo, tabla de contingencia y test de hipótesis 2, diseño de casos y controles con el calculo de Odds Ratio cruda y posteriormente ajustada (IC al 95% utilizando regresión logística. Resultados: No se observaron diferencias significativas en las variables de características personales y de lugar. La tasa de ataque en los residentes fue del 30,1% y en trabajadores fue del 21,12%. En el calculo de la Odds Ratio ajustada sólo tuvo valores de relación causal la mousse de nata (Odds Ratio ajustada=4,66; IC-95% 1,15-18,91; p=0,031. Se remitieron 10 muestras de heces de enfermos para su análisis, no detectándose ninguna bacteria patógena, pero si se aisló en 3 de ellas virus Norwal-Like. Conclusiones: El hallazgo de la mousse de nata como posible responsable del brote supone una primicia en la presencia de virus Norwalk, pero este resultado está sujeto a limitaciones, como el posible sesgo de clasificación por no recuerdo de consumo de alimentos. Aún así, supone un elemento a tener en cuenta en el control de gastroenteritis agudas por virus.

    Aim: The aim of work was presentation of several socio-demographic, clinical and laboratory characteristics of gastroenteritis caused by rotavirus. The examinees and methods: The examinees were children under the age of five years treated at the Pediatric Clinic due to acute gastroenteritis caused by rotavirus. Rotavirus is isolated by method chromatographic immunoassay by Cer Test Biotec. Results: From the total number of patients (850) suffering from acute gastroenteritis, feces test on bacteria, viruses. protozoa and fungi was positive in 425 (49.76%) cases. From this number the test on bacteria was positive in 248 (58.62%) cases, on viruses it was positive in 165 (39.0%), on protozoa in 9 (2.12%) cases and on fungi only one case. Rotavirus was the most frequent one in viral test, it was isolated in 142 (86.06%) cases, adenoviruses were found in 9 (5.45%) cases and noroviruses in only one case. The same feces sample that contained rotavirus and adenoviruses were isolated in five cases, whereas rotavirus with bacteria was isolated in the same feces sample in five cases. The biggest number of cases 62 (43.66%) were of the age 6-12 months, whereas the smallest number 10 (7.04%) cases were of the age 37-60 months. There were 76 (53.52%) of cases of male gender, from rural areas there were 81 (57.04%) cases and there were 58 (40.80%) cases during the summer period. Among the clinical symptoms the most prominent were diarrhea, vomiting, high temperature, whereas the different degree of dehydration were present in all cases (the most common one was moderate dehydration). The most frequent one was isonatremic dehydration in 91 (64.08%) cases, less frequent one was hypernatremic dehydration in 14 (9.85%) cases. The majority of cases (97.89%) had lower blood pH values, whereas 67 (47.17%) cases had pH values that varied from 7.16 -7.20 (curve peak), normal values were registered in only 3 (2.11%) cases.

  1. Hospitalizations due to rotavirus gastroenteritis in Catalonia, Spain, 2003-2008

    Science.gov (United States)

    2011-01-01

    Background Rotavirus is the most common cause of severe gastroenteritis among young children in Spain and worldwide. We evaluated hospitalizations due to community and hospital-acquired rotavirus gastroenteritis (RVGE) and estimated related costs in children under 5 years old in Catalonia, Spain. Results We analyzed hospital discharge data from the Catalan Health Services regarding hospital admissions coded as infectious gastroenteritis in children under 5 for the period 2003-2008. In order to estimate admission incidence, we used population estimates for each study year published by the Statistic Institut of Catalonia (Idescat). The costs associated with hospital admissions due to rotavirus diarrhea were estimated for the same years. A decision tree model was used to estimate the threshold cost of rotavirus vaccine to achieve cost savings from the healthcare system perspective in Catalonia. From 2003 through 2008, 10655 children under 5 years old were admitted with infectious gastroenteritis (IGE). Twenty-two percent of these admissions were coded as RVGE, yielding an estimated average annual incidence of 104 RVGE hospitalizations per 100000 children in Catalonia. Eighty seven percent of admissions for RVGE occurred during December through March. The mean hospital stay was 3.7 days, 0.6 days longer than for other IGE. An additional 892 cases of presumed nosocomial RVGE were detected, yielding an incidence of 2.5 cases per 1000 child admissions. Total rotavirus hospitalization costs due to community acquired RVGE for the years 2003 and 2008 were 431,593 and 809,224 €, respectively. According to the estimated incidence and hospitalization costs, immunization would result in health system cost savings if the cost of the vaccine was 1.93 € or less. At a vaccine cost of 187 € the incremental cost per hospitalization prevented is 195,388 € (CI 95% 159,300; 238,400). Conclusions The burden of hospitalizations attributable to rotavirus appeared to be lower in

    Familiarity with the spectrum of findings in the different imaging modalities appears essential. Radiographically, significant changes include Charcot joints of the tarsus (destructive type) and bone absorption of the forefoot (mutilating type). In diabetic foot problems, magnetic resonance imaging and leukocyte scintigraphy appear to be the most effective tools for detection of osteomyelitis, and a negative study makes osteomyelitis unlikely. However, the findings of both techniques in active, noninfected neuropathic osteoarthropathy may be indistinguishable from those of osteomyelitis. (orig.) [Deutsch] Da der diabetische Fuss zu einer der haeufigsten Komplikationen der Grunderkrankung zaehlt, muss das Befundspektrum bei den verschiedenen bildgebenden Verfahren bekannt sein. Bei der diabetischen Osteoarthropathie werden uebersichtsradiographisch 2 Formen unterschieden: der destruierende Typ, der die Tarsalknochen bevorzugt, und der mutilierende Typ, welcher sich an den Roehrenknochen des Fusses manifestiert. Die Magnetresonanztomographie und die Leukozytenszintigraphie sind zum Nachweis bzw. Ausschluss einer Osteomyelitis am besten geeignet. Aber auch diese Methoden koennen nicht sicher eine nicht infizierte, aktive Osteoarthropathie von einer Osteomyelitis differenzieren. (orig.)

    The effect of rotavirus in developed countries is mainly economic. This study aimed to assess the indirect costs induced by rotavirus acute gastroenteritis (RVAGE) in Spain. A prospective observational study was conducted from October 2008 to June 2009. It included 682 children up to 5 years of age with acute gastroenteritis (AGE) who attended primary care (n = 18) and emergency room/hospital settings (n = 10), covering the regions of Galicia and Asturias (North-west Spain). All non-medical expenses incurred throughout the episode were recorded in detail using personal interviews and telephone contact. Among the 682 enrolled children, 207 (30.4%) were rotavirus positive and 170 (25%) had received at least one dose of rotavirus vaccine. The mean (standard deviation) indirect cost caused by an episode of AGE was estimated at 135.17 (182.70) Euros. Costs were 1.74-fold higher when AGE was caused by rotavirus compared with other etiologies: 192.7 (219.8) Euros vs. 111.6 (163.5) Euros (p purchase of material.

    2018-01-01

    Full Text Available Introduction. Eosinophilic gastroenteritis (EGE is a rare idiopathic disease that can affect one or more organs of the digestive tract. It has an estimated incidence of 1–20 cases per 100,000 patients. Klein et al. classified EGE into 3 subtypes: predominant mucosal, muscular, or subserosal. Clinical Case. We report a case of a 32-year-old woman, who presented with diffuse abdominal pain, nausea, postprandial infarction, diarrhea, and moderate ascites of three-week evolution. The rest of physical examination did not show alterations. The past medical history was unremarkable. Laboratory test results revealed peripheral blood eosinophilia. Abdominal CT scan revealed diffuse and concentric parietal thickening of the distal 2/3 of esophagus, moderate volume ascites, and small bowel wall thickening and distension on the left quadrants. The paracentesis revealed 93.3% of eosinophils. The colon biopsies evidenced an increase in the number of eosinophils. Secondary causes of eosinophilia were excluded. The patient was treated with oral prednisolone 40 mg/day with immediate clinical and analytical improvement. Conclusion. Eosinophilic gastroenteritis is a rare condition with a nonspecific and highly variable clinical presentation, which requires a high level of clinical suspicion. It is a diagnosis of exclusion. Secondary causes of eosinophilia such as intestinal tuberculosis, parasitosis, and malignant neoplasms should be excluded.

  11. Diapers in war zones: ethnomedical factors in acute childhood gastroenteritis in Peshawar, Pakistan.

    Directory of Open Access Journals (Sweden)

    Saira H Zaidi

    Full Text Available This article considers ethnomedical knowledge and practices among parents related to contraction of acute gastroenteritis among children in Peshawar, Pakistan. Research methods included analysis of the Emergency Pediatric Services' admission register, a structured interview administered to 47 parents of patients seen in the Khyber Medical College Teaching Hospital, semi-structured interviews of 12 staff, and four home visits among families with children treated at the hospital. The use of native research assistants and participant observation contributed to the reliability of the findings, though the ethnographic, home-visit sample is small. Our research indicated that infection rates are exacerbated in homes through two culturally salient practices and one socioeconomic condition. Various misconceptions propagate the recurrence or perserverance of acute gastroenteritis including assumptions about teething leading to poor knowledge of disease etiology, rehydration solutions leading to increased severity of disease, and diaper usage leading to the spread of disease. In our Discussion, we suggest how hospital structures of authority and gender hierarchy may impact hospital interactions, the flow of information, and its respective importance to the patient's parents leading to possible propagation of disease. These ethnographic data offer a relatively brief but targeted course of action to improve the effectiveness of prevention and treatment efforts.

    Heinävesi, a Finnish municipality with a population of 4860 inhabitants, had an outbreak of gastroenteritis in March 1998. On the basis of an epidemiologic survey, an estimated 1700-3000 cases of acute gastroenteritis occurred during the outbreak. Municipal water consumption was found to be associated with illness (risk ratio [RR]=3.5, 95% confidence interval, 3.11>RR>3.96). Norwalk-like virus (NLV) genogroup II (GGII) was identified in untreated water, treated water, and 4 tap water samples by use of reverse transcription-polymerase chain reaction. This was the first time NLVs had been detected in municipal tap water. Fifteen of 27 patient stool samples had NLV GGII, with an identical amplification product to that found in the water samples, indicating that the outbreak was caused by this virus. In some patients, NLV genogroup I was also encountered. This virus, however, could not be detected in the water samples. Inadequate chlorination contributed to the survival of the virus in the water.

    A nosocomial outbreak of rotavirus gastroenteritis involving 52 newborns occurred between June and September 1988 at the University Children's Hospital of Freiburg, Federal Republic of Germany. Stools from 27 representative patients were examined for rotavirus serotypes, using a monoclonal antibody-based enzyme-linked immunosorbent assay. The electropherotype was also examined by polyacrylamide gel electrophoresis of genomic RNA. As many as 18 patients were found to be infected by serotype 4, subtype 4B strain, and in all of them the same electropherotype was detected. Although rotavirus from the remaining nine patients could not be typed, the electropherotype in four was identical to that of the serotype 4, subtype 4B strain. Thus, most of the patients in the outbreak were infected by the same rotavirus strain. Retrospective epidemiological studies showed that the 4B strain began to circulate at the hospital in January 1988, whereas only rotavirus serotypes 1, 3, and 4A were detected in 1985-1987. The primary case of the outbreak was presumably a newborn with acute gastroenteritis, admitted to the hospital from a small maternity unit in the same urban area. During the outbreak, 12 of 44 healthy newborns in the nurseries of the Children's Hospital and other maternity hospitals were found to be asymptomatic rotavirus carriers, and in three of the newborns the same 4B strain was detected. This is the first reported outbreak caused by a serotype 4, subtype 4B strain.

    2015-08-01

    Although several studies have investigated the effects of temperature on the incidence of infectious gastrointestinal disease in a single city or region, few have investigated variations in this association using nationwide data. We obtained weekly data, gathered between 2000 and 2012, pertaining to infectious gastroenteritis cases and weather variability in all 47 Japanese prefectures. A two-stage analysis was used to assess the nonlinear and delayed relationship between temperature and morbidity. In the first stage, a Poisson regression allowing for overdispersion in a distributed lag nonlinear model was used to estimate the prefecture-specific effects of temperature on morbidity. In the second stage, a multivariate meta-analysis was applied to pool estimates at the national level. The pooled overall relative risk (RR) was highest in the 59.9th percentile of temperature (RR, 1.08; 95% CI: 1.01, 1.15). Meta-analysis results also indicated that the estimated pooled RR at lower temperatures (25th percentile) began immediately but did not persist, whereas an identical estimate at a higher temperature (75th percentile) was delayed but persisted for several weeks. Our results suggest that public health strategies aimed at controlling temperature-related infectious gastroenteritis may be more effective when tailored according to region-specific weather conditions.

    Full Text Available Introduction: Accidental ingestion of magnetic foreign bodies has become more common due to increased availability of objects and toys with magnetic elements. The majority of them traverse the gastrointestinal system spontaneously without complication. However, ingestion of multiple magnets may require surgical resolution. Magnet ingestion usually does not cause serious complications, but in case of multiple magnet ingestion or ingestion of magnet and a metal object, it could cause intestinal obstruction, fistula formation or even perforation. Case report: We report case of a transmesocolic double gastro-enteric fistula formation following ingestion of 28 small magnets in a 17 months old boy. No history of foreign body ingestion could be obtained from parents therefore the patient was treated conservatively in a pediatric clinic for vomiting, dehydration, upper respiratory tract infection and suspicion of upper digestive tract bleeding. After 48 h he was sent in our clinic for surgical evaluation. Intraoperatively double transmesocolic gastro-enteric fistula was found. After separation of de gastric and enteral walls, resection of gastric wall and intestinal segment containing the two perforations was performed, followed by gastric suture in two layers and entero-enteric anastomosis. A total of 28 magnets were removed from the stomach and small intestine. Conclusion: Single magnet ingestion is treated as non-magnetic foreign body. Multiple magnet ingestion should be closely monitored and surgical approach could be the best option to prevent or to cure its complications.

    Annual mortality rates due to infectious diarrhea are about 2.2 million; children are the most vulnerable age group to severe gastroenteritis, representing group A rotaviruses as the main cause of disease. One of the main factors of rotavirus pathogenesis is the NSP4 protein, which has been characterized as a viral toxin involved in triggering several cellular responses leading to diarrhea. Furthermore, the rotavirus protein NSP1 has been associated with interferon production inhibition by inducing the degradation of interferon regulatory factors IRF3, IRF5, and IRF7. On the other hand, probiotics such as Bifidobacterium and Lactobacillus species in combination with prebiotics such as inulin, HMO, scGOS, lcFOS have been associated with improved generalized antiviral response and anti-rotavirus effect by the reduction of rotavirus infectivity and viral shedding, decreased expression of NSP4 and increased levels of specific anti-rotavirus IgAs. Moreover, these probiotics and prebiotics have been related to shorter duration and severity of rotavirus diarrhea, to the prevention of infection and reduced incidence of reinfections. In this review we will discuss in detail about the rotavirus pathogenesis and immunity, and how probiotics such as Lactobacillus and Bifidobacterium species in combination with prebiotics have been associated with the prevention or modulation of rotavirus severe gastroenteritis.

    Group A rotaviruses (RVA) are the leading cause of acute gastroenteritis (AGE) in young (aged rotavirus are presently known, most RVA infections in humans worldwide are related to five major G/P combinations: G1P[8], G2P[4], G3P[8], G4P[8], and G9P[8]. To provide the hospitals of the Italian surveillance network with update information on RVA AGE. During RVA gastroenteritis surveillance in Italy in 2012-14, a total of 2341 RVA-positive faecal samples were collected from children hospitalized with AGE, and RVA strains were genotyped following standard EuroRotaNet protocols. Most strains analysed belonged to the five major human genotypes and 118 out of 2341 (5.0%) were reported to be hospital-acquired. Comparison of the distributions of the RVA genotypes circulating in the community or associated with nosocomial infections showed a different distribution of genotypes circulating inside the hospital wards, with respect to those observed in the community. G1P[8] and G9P[8] RVA strains were detected frequently, whereas G12P[8] caused a single large nosocomial outbreak. The information from this study will be useful to implement guidelines for preventing RVA AGE and optimizing the management of patients in hospital wards.

    Burgkart, Rainer; Gollwitzer, Hans; Holzapfel, Boris; Rudert, Maximilian; Rechl, Hans; Gradinger, Reiner

    Die Behandlung der Knochentumoren unterlag in den letzten 20 Jahren einem raschen und stetigen Wandel, was zum einen auf die verbesserten Therapieerfolge durch den Einsatz von neoadjuvanten Therapieformen zurückzuführen ist, und andererseits von medizintechnischen Entwicklungen bezüglich moderner Schnittbilddiagnostik, neuer 3D Operationsplanungsverfahren wie das Rapid Prototyping und adaptiv modularer Tumorendoprothesensystemen u. a. begleitet wurde. Gerade die technischen Entwicklungen haben dazu geführt, daß im Bereich der Extremitäten und der Wirbelsäule radikalere Eingriffe durchgeführt werden können, was die lokale Tumorkontrolle wesentlich verbessert hat. In zunehmenden Maße werden deshalb nicht nur Kurzzeiterfolge sondern auch mittel- und langfristige Fortschritte bei der Behandlung der malignen Knochentumoren einschließlich der Metastasenbehandlung erreicht. Grundlage der Therapie ist dabei immer primär die Sicherung der Diagnose mittels Biopsie und die bildgebende sowie histologische Stadieneinteilung des malignen Tumors. Nach der Tumorresektion kann die Rekonstruktion biologisch oder mit Endoprothesensystemen erfolgen. Gerade die weiterentwickelten modularen Systeme führen zu guten funktionellen Ergebnissen mit langen Standzeiten und einer reduzierten Komplikationsrate. Individuell angefertigte Implantate sind vor allem im Bereich der Rekonstruktion komplexer Beckentumoren von großer klinischer Bedeutung.

    2001-03-01

    Full Text Available Nicht nur Fachleute beklagen die mangelnde Qualität der deutschen Filme und Werbespots. Eine Ursache für die mangelnden Erfolge solcher mediatisierten Kommunikation liegt in einer systematischen Interaktionsstörung zwischen der Medienpraxis und Medienforschung. Die aktuelle deutschsprachige Medienwirkungsforschung entzieht sich weitgehend der gebotenen und von Macher/innen erwarteten gesellschafts- und praxisdienenden Aufgabe. Der Hauptgrund hierfür liegt darin, dass die zumeist zugrunde gelegten Forschungsrahmen (conceptual frameworks praxisrelevante Kategorien wie die der Zuschauerperspektive weitgehend ignorieren. Das hier vorgestellte interaktionistische Modell der mediatisierten Kommunikation will deshalb als Forschungsrahmen den Blick auf Übersehenes richten. Darüber hinaus soll dieses Modell auch für Praktiker als Prüfschema zur Mediaplanung dienen, mediatisierte Kommunikation - gemessen am eigenen Anspruch - kalkulierbarer und damit auch erfolgreicher zu machen.

    Die computergestützte bildbasierte Analyse der Herzfunktionen ist mittlerweile Standard in der Kardiologie. Die verfügbaren Produkte erfordern meist ein hohes Maß an Benutzerinteraktion und somit einen erhöhten Zeitaufwand. In dieser Arbeit wird ein Ansatz vorgestellt, der dem Kardiologen eine größtenteils automatische Analyse der Herzfunktionen mittels MRT-Bilddaten ermöglicht und damit Zeitersparnis schafft. Hierbei werden alle relevanten herzphysiologsichen Parameter berechnet und mithilfe von Diagrammen und Graphen visualisiert. Diese Berechnungen werden evaluiert, indem die ermittelten Werte mit manuell vermessenen verglichen werden. Der hierbei berechnete mittlere Fehler liegt mit 2,85 mm für die Wanddicke und 1,61 mm für die Wanddickenzunahme immer noch im Bereich einer Pixelgrösse der verwendeten Bilder.

    Increased gut permeability to macromolecules is thought to be an important factor in the development of food hypersensitivity. The latter can develop in the course of acute gastroenteritis and could play a role in infantile eczema. The authors studied gut permeability in 10 normal adults, 11 control children, 7 children with acute gastroenteritis, and 8 patients with infantile eczema, making use of [ 51 Cr]EDTA as probe molecule. [ 51 Cr]EDTA was given orally (50-100 microCi); 24-h urinary excretion of [ 51 Cr]EDTA was measured and expressed as a percentage of the oral dose. Mean and standard error were 2.35 +/- 0.24, 2.51 +/- 0.21, 9.96 +/- 3.44, and 10.90 +/- 2.05 in normal adults, control children, and gastroenteritis and eczema patients, respectively. Differences between controls and either gastroenteritis (p less than 0.001) or eczema (p less than 0.001) patients are significant. The results support the hypothesis that increased gut permeability could play a role in food hypersensitivity

  20. Efficacy of intravenous ondansetron to prevent vomiting episodes in acute gastroenteritis: a randomized, double blind, and controlled trial

    Full Text Available Acute gastroenteritis is one of the most common infectious diseases of childhood. Its symptoms are vomiting, diarrhea, and dehydration. In the emergency ward, intravenous rather than oral rehydration is usually preferred because of the high likelihood of emesis. Treatments to reduce emesis are of value in improving the rehydration procedure. Our study is a double-blind randomized trial and proposes the use of ondansetron as an anti-emetic drug to treat children with acute gastroenteritis. Seventy-four in-patients, aged 3 months to 15 years, were enrolled and randomly assigned to an ondansetron or placebo group. Inclusion criteria were the diagnosis of acute gastroenteritis and the absence of other diseases or allergies to drugs. A single bolus (0.15 mg/kg of ondansetron was injected intravenously; normal 0.9% saline solution was used as a placebo. This treatment induced vomiting cessation in the ondansetron group significantly in comparison to the placebo group. The length of the hospital stay and the oral rehydration fluid volume were similar in the two groups and no adverse effects were noticed. Thus, safety, low cost, and overall bene­fit of ondansetron treatment suggests that this drug can be administered successfully to children with acute gastroenteritis.

    All over the world, children and adults are severely affected by acute gastroenteritis, caused by one of the emerging enteric pathogens, rotavirus C (RVC). At present, no extensive surveillance program is running for RVC in India, and its prevalence is largely unknown except cases of local outbreaks. Here, we intended to detect the presence of RVC in diarrheic children visiting or admitted to hospitals in Haldwani (state of Uttarakhand, India), a city located in the foothills of the Himalayas. During 2010-2013, we screened 119 samples for RVC by an RVC VP6 gene-specific RT-PCR. Of these, 38 (31.93%) were found positive, which is higher than the incidence rates reported so far from India. The phylogenetic analysis of the derived nucleotide sequences from one of the human RVC (HuRVC) isolates, designated as HuRVC/H28/2013/India, showed that the study isolate belongs to genotype I2, P2 and E2 for RVC structural genes 6 and 4 (VP6, and VP4) and non-structural gene 4 (NSP4), respectively. Furthermore, the VP6 gene of HuRVC/H28/2013/India shows the highest similarity to a recently-reported human-like porcine RVC (PoRVC/ASM140/2013/India, KT932963) from India suggesting zoonotic transmission. We also report a full-length NSP4 gene sequence of human RVC from India. Under the One-health platforms there is a need to launch combined human and animal RVC surveillance programs for a better understanding of the epidemiology of RVC infections and for implementing control strategies. Reoviridae , possess 11 double-stranded segments of RNA that encode six structural viral proteins (VP1, VP2, VP3, VP4, VP6, VP7) and five/six non-structural proteins (NSP1-NSP5/6) [7]. Based on the antigenic properties of the major inner capsid protein (VP6), RVs are subdivided into eight well-characterized species (A-H) and two putative species viz. I and J [8-10]. Humans and other mammalian species are affected by species A, B, C and H rotaviruses and birds by species D, F and G, and species E has

    In 1999, in Toledo, Ohio, an outbreak of gastroenteritis occurred among people who had attended a Christmas dinner banquet and had eaten food prepared by a local caterer. Overall, 93 of the 137 attendees (67.9 percent) reported illness. Eight sought medical care, and one was hospitalized. Case-control studies revealed that the illness was associated with eating tossed salad (odds ratio [OR] = 2.5, 95 percent confidence interval [CI] = 1.02-6.26). Eleven of 12 stool specimens that were taken from ill people tested positive for a Norwalk-like virus (NLV) but were negative for E. coli O157:H7, Salmonella, and Shigella. The primary source of the outbreak was not determined, but an infected food handler may have played a role in the transmission of the virus. The catering facility had been cited frequently for food safety and hygiene violations. None of the personnel or food handlers at this facility had been appropriately trained in safe food-handling practices, nor had the personnel at another local caterer that had prepared food items suspected of causing a multistate outbreak of NLVs. In Toledo, food service operations with trained personnel/food handlers received better inspection reports than food service operations without trained personnel and were less likely to contribute to foodborne outbreaks. Training of personnel and food handlers may be important for preventing outbreaks.

    In March 1999, an outbreak of gastroenteritis occurred affecting 30 day-care centres served by the same caterer. A retrospective cohort study was performed in 13 randomly selected day-care centres to determine the source and mode of transmission. Electron microscopy and PCR were used to verify the diagnosis. The overall attack rate (AR) was 37% (195/524): 30% in children and 62% in adults. Modified by the age of the patient, eating pumpkin salad served on 1 March was associated with becoming an early case (odds ratio = 3.9; 95% confidence interval 1.8-8.8). No significant association was found between food consumption and becoming a late case. The primary food-borne AR was 27% and the secondary AR was 14%. The same genotype of Norwalk-like virus was found in 5 cases and in 1 ill and 1 asymptomatic food-handler. Contamination by 1 of the food-handlers seems the most likely route of spread of the virus and underlines the importance of strict hygienic routines.

    Historical outbreaks can be an important source of information in the understanding of norovirus evolution and epidemiology. Here, we revisit an outbreak of undiagnosed gastroenteritis that occurred in Shippensburg, Pennsylvania in 1972. Nearly 5000 people fell ill over the course of 10 days. Symptoms included diarrhea, vomiting, stomach cramps, and fever, lasting for a median of 24 h. Using current techniques, including next-generation sequencing of full-length viral genomic amplicons, we identified an unusual norovirus recombinant (GII.Pg/GII.3) in nine of 15 available stool samples from the outbreak. This particular recombinant virus has not been reported in recent decades, although GII.3 and GII.Pg genotypes have been detected individually in current epidemic strains. The consensus nucleotide sequences were nearly identical among the four viral genomes analysed, although each strain had three to seven positions in the genome with heterogenous non-synonymous nucleotide subpopulations. Two of these resulting amino acid polymorphisms were conserved in frequency among all four cases, consistent with common source exposure and successful transmission of a mixed viral population. Continued investigation of variant nucleotide populations and recombination events among ancestral norovirus strains such as the Shippensburg virus may provide unique insight into the origin of contemporary strains.

    Controlled water turbines were first introduced in the second half of the 19th century. The report takes a look at the history of controlled turbines, including those inventions and technologies that paved the way for water turbines as we know them today and for turbine speed control. The report is based on a lecture presented by the author on 10 Nov 1998 in the opening session of the 10th international seminar on hydroelectric power systems at the university of Vienna. The contents are presented in more detail and illustrated by examples. [German] Seit langem widmen sich Wissenschaftshistoriker und auch Ingenieure der Erforschung und Aufarbeitung der Technikgeschichte als eigenstaendige Disziplin der Wissenschaftsgeschichte, wofuer an vielen Universitaeten und Hochschulen entsprechende Lehrstuehle bestehen. Auch an der Entwicklung der Regelungstechnik im Allgemeinen ist das Interesse mit langem erwacht. Die ersten geregelten Wasserturbinen wurden in der zweiten Haelfte des 19. Jahrhunderts bekannt und so ist es denn auch angebracht, die zumindest 130 Jahre der Entwicklungsgeschichte dieser Turbinenregelung darzustellen. Dies ginge nicht, ohne zunaechst auch auf jene anderen Erfindungen und Technologien kurz zurueckzublicken, die Wegbereiter fuer die heutigen Wasserturbinen und fuer die ersten Ansaetze zu deren Drehzahlregelung waren. Diese Arbeit beruht auf einem Hauptvortrag, der am 10 November 1998 in der Eroeffnungssitzung des 10. Internationalen Seminars Wasserkraftanlagen an der Technischen Universitaet Wien gehalten wurde. Gegenueber der schriftlichen Fassung jenes Vortrags wird mit diesem Heft den an diesem speziellen Sektor der Technikgeschichte interessierten Kollegen eine stark erweiterte Fassung vorgelegt.

    Full Text Available Introducción: La potabilidad del agua induce a descartar el posible origen hídrico de los brotes. El objetivo fue investigar un brote de gastroenteritis por agua potable de suministro público. Métodos: Después de la notificación de un brote de gastroenteritis en el municipio de Baqueira (Valle de Arán se diseñó un estudio epidemiológico de cohortes retrospectivo. Mediante un muestreo sistemático se eligió a 87 personas hospedadas en los hoteles y a 62 alojadas en diferentes apartamentos. Se recogió información sobre 4 factores (consumo de agua de la red, bocadillos, agua y alimentos en las pistas de esquí y presencia de síntomas. Se determinó la existencia de cloro, se analizó el agua de la red y se realizó un coprocultivo a 4 enfermos. La implicación de cada factor se determinó con el riesgo relativo (RR y su intervalo de confianza (IC del 95%. Resultados: La incidencia de gastroenteritis fue del 51,0% (76/149. Los porcentajes de los síntomas fueron los siguientes: fiebre, 27,0%; diarrea, 87,5%; náuseas, 50,7%; vómitos, 30,3%, y dolor abdominal, 80,0%. El único factor que presentó un riesgo estadísticamente significativo fue el consumo de agua de la red (RR = 11,0; IC del 95%, 1,6-74,7. La calificación sanitaria del agua fue de potabilidad. Se observó un defecto de situación del clorador en el depósito, que fue corregido. Se recomendó incrementar aún más las concentraciones de cloro, lo cual se acompañó de una disminución de los casos. Los coprocultivos de los 4 enfermos fueron negativos para las enterobacterias investigadas. Conclusiones: El estudio demuestra la posibilidad de presentación de brotes hídricos por agua cualificada como potable y sugiere la necesidad de mejorar la investigación microbiológica (determinación de protozoos y virus en este tipo de brotes.

El objetivo del estudio es investigar las causas del origen y transmisión de un brote de gastroenteritis aguda por virus Norwal- Like. Método: En una residencia de ancianos con 141 residentes y 71 trabajadores expuestos, se investigó la relación entre un brote de gastroenteritis aguda y distintas variables: características personales, de lugar, fecha de inicio de los síntomas, clínica de la enfermedad y factores causales (alimentos y agua de consumo. Se realizó un estudio descriptivo, tabla de contingencia y test de hipótesis 2, diseño de casos y controles con el calculo de Odds Ratio cruda y posteriormente ajustada (IC al 95% utilizando regresión logística. Resultados: No se observaron diferencias significativas en las variables de características personales y de lugar. La tasa de ataque en los residentes fue del 30,1% y en trabajadores fue del 21,12%. En el calculo de la Odds Ratio ajustada sólo tuvo valores de relación causal la mousse de nata (Odds Ratio ajustada=4,66; IC-95% 1,15- 18,91; p=0,031. Se remitieron 10 muestras de heces de enfermos para su análisis, no detectándose ninguna bacteria patógena, pero si se aisló en 3 de ellas virus Norwal-Like. Conclusiones: El hallazgo de la mousse de nata como posible responsable del brote supone una primicia en la presencia de virus Norwalk, pero este resultado está sujeto a limitaciones, como el posible sesgo de clasificación por no recuerdo de consumo de alimentos. Aún así, supone un elemento a tener en cuenta en el control de gastroenteritis agudas por virus.

    The objective was to validate the clinical dehydration scale (CDS) for children with gastroenteritis in a different pediatric emergency department (ED) from where it was initially derived and validated. A prospective cohort study was performed in a tertiary care pediatric ED over a 1-year period. A sample of triage nurses were trained in applying the CDS. The CDS consists of four clinical characteristics (general appearance, eyes, mucous membranes, and tears), each of which are scored 0, 1, or 2 for a total score of 0 to 8, with 0 representing no dehydration; 1 to 4, some dehydration; and 5 to 8, moderate/severe dehydration. Children 1 month to 5 years of age with vomiting and/or diarrhea who had the CDS documented at triage and a final diagnosis of gastroenteritis, gastritis, or enteritis were enrolled. Exclusion criteria included a chronic disease, treatment with intravenous (IV) rehydration within the previous 24 hours, visit to the ED for the same illness in the 7 days prior to arrival, and diarrhea of more than 10 days' duration. The primary outcome was the length of stay (LOS) in the ED from the time of seeing a physician to discharge, analyzed with a Kruskal-Wallis test. From April 2008 to March 2009, 150 patients with a mean (+/-SD) age of 22 (+/-14) months (range = 4 months to 4 years) were enrolled. Fifty-six patients had no dehydration, 74 had some dehydration, and 20 had moderate/severe dehydration. The median LOS in the ED after being seen by a physician was significantly longer as children appeared more dehydrated according to the CDS: 54 minutes (interquartile range [IQR] = 26-175 minutes), 128 minutes (IQR = 25-334 minutes), and 425 minutes (IQR = 218-673 minutes) for the no, some, and moderate/severe dehydration groups, respectively (p children with gastroenteritis in a different pediatric center than the original one where it was developed. It is a good predictor of LOS in the ED after being seen by a physician. (c) 2010 by the Society for

    The efficacy of the pentavalent rotavirus vaccine (PRV), RotaTeq(®), was evaluated in a double-blind, placebo-controlled, multicenter Phase III clinical trial conducted (April 2007-March 2009) in 3 low-income countries in Africa: Ghana, Kenya, and Mali. In total, 5468 infants were randomized 1:1 to receive 3 doses of PRV/placebo at approximately 6, 10, and 14 weeks of age; concomitant administration with routine EPI vaccines, including OPV, was allowed. HIV-infected infants were not excluded. The primary endpoint, vaccine efficacy (VE) against severe-rotavirus gastroenteritis (RVGE), as measured by Vesikari scoring system (VSS, score ≥11), from ≥14 days following Dose 3 through a follow-up period of nearly 2 years in the combined 3 African countries, and secondary endpoints by total follow-up period have been previously reported. In this study, we report post hoc subgroup analyses on secondary endpoints of public health importance. VE against RVGE of any severity was 49.2% (95%CI: 29.9, 63.5) through the first year of life and 30.5% (95%CI: 16.7, 42.2) through the complete follow-up period. VE against severe-gastroenteritis of any etiology was 21.5% (95%CI: vaccine-contained G and P types (G1-G4, P1A[8]), (ii) non-vaccine G types (G8, G9, G10), and (iii) non-vaccine P types (P1B[4], P2A[6]) was 34.0% (95%CI:11.2, 51.2), 81.8% (95%CI:16.5, 98.0) and 40.7% (95%CI:8.4, 62.1), respectively. There was a trend towards higher VE with higher disease severity, although in some cases the numbers were small. In African countries with high under-5 mortality rates, PRV significantly reduced RVGE through nearly 2 years of follow-up; more modest reductions were observed against gastroenteritis of any etiology. PRV provides protection against severe-RVGE caused by diverse rotavirus genotypes, including those not contained in the vaccine. Copyright © 2012 Elsevier Ltd. All rights reserved.

  15. Effects of the van der Waals Force on the Dynamics Performance for a Micro Resonant Pressure Sensor

    Full Text Available The micro resonant pressure sensor outputs the frequency signals where the distortion does not take place in a long distance transmission. As the dimensions of the sensor decrease, the effects of the van der Waals forces should be considered. Here, a coupled dynamic model of the micro resonant pressure sensor is proposed and its coupled dynamic equation is given in which the van der Waals force is considered. By the equation, the effects of the van der Waals force on the natural frequencies and vibration amplitudes of the micro resonant pressure sensor are investigated. Results show that the natural frequency and the vibrating amplitudes of the micro resonant pressure sensor are affected significantly by van der Waals force for a small clearance between the film and the base plate, a small initial tension stress of the film, and some other conditions.

    Full Text Available Background: Acute gastroenteritis (AGE can be caused by a wide array of pathogens, including bacteria, viruses, and parasites. A prospective study to investigate the epidemiology and clinical presentation in young children hospitalized with AGE was conducted in a medical center in southern Taiwan. Methods: Patients aged less than 5 years who was hospitalized due to AGE in National Cheng Kung University Hospital were enrolled from July 2014 to June 2016. The demographic information, clinical features and laboratory data were collected by chart reviews, and stool samples were sent to Centers of Disease Control, Taiwan (Taiwan CDC for a panel of pathogen identification consisting of two viruses, nine bacteria, and five parasites. Results: Totally 441 patients were enrolled in this study. Salmonella spp. was the leading cause of disease (21.8%, followed by norovirus (17.0%, Clostridium difficile (9.5%, and rotavirus (9.3%. Norovirus identification rate was the highest among patients less than 6 months of age, while Salmonella was highest among patients between 2 and 3 years old. Patients with Salmonella infection frequently presented with fever, lethargy, bloody stool, and elevated serum level of C-reactive protein (CRP; norovirus and rotavirus infection frequently presented with vomiting. Salmonella gastroenteritis also resulted in longer hospitalization and more frequent antibiotics administration. C. difficile could be isolated from both gastroenteritis patients and control children. Conclusion: Salmonella spp. was the most common pathogen of AGE in hospitalized children in southern Taiwan during 2014–2016, followed by norovirus and rotavirus. Further monitoring of epidemiology characteristics among cardinal pathogens of pediatric gastroenteritis is necessary. Keywords: Acute gastroenteritis, Children, Epidemiology, Taiwan

    Walter, Wolfram M.

    Die Digitalisierung schreitet mit großen Schritten voran. Dies wirkt sich nicht nur auf die Gesellschaft im Grundsatz, sondern auch auf das Verhalten der Kunden aus. Neue Kommunikationswege beschleunigen die Interaktion zwischen Unternehmen und Verbraucher. Im Vergleich mit großen Internetfirmen werden etablierte Dienstleistungsunternehmen - vom Energieversorger bis zu Versicherungen - stark unter Druck gesetzt, sich noch intensiver mit dem Kundenservice auseinanderzusetzen. Dies wird nur möglich sein, wenn sich die Organisationen entsprechend positionieren und sich frühzeitig auf die Veränderungen einstellen. Hieraus ergeben sich mehr Chancen als Risiken, zumal es nicht nur neue Prozesse, sondern auch neue Berufsbilder geben wird.

    Previously reported outbreaks of norovirus gastroenteritis associated with aircraft have been limited to transmission during a single flight sector. During October 2009, an outbreak of diarrhea and vomiting occurred among different groups of flight attendants who had worked on separate flight sectors on the same airplane. We investigated the cause of the outbreak and whether the illnesses were attributable to work on the airplane. Information was obtained from flight attendants on demographic characteristics, symptoms, and possible transmission risk factors. Case patients were defined as flight attendants with diarrhea or vomiting airplane during 13-18 October 2009. Stool samples were tested for norovirus RNA. A passenger had vomited on the Boeing 777-200 airplane on the 13 October flight sector. Sixty-three (82%) of 77 flight attendants who worked on the airplane during 13-18 October provided information, and 27 (43%) met the case definition. The attack rate among flight attendants decreased significantly over successive flight sectors from 13 October onward (P airplane during successive flight sectors. Airlines should make provision for adequate disinfection of airplanes with use of products effective against norovirus and other common infectious agents after vomiting has occurred.

    In an outbreak of acute gastroenteritis which originated in a restaurant in Chiba, Japan, in December, 1987, small round structured virus (SRSV) particles were observed by electron microscopy in 14 of 16 stool specimens from patients. The particles were 30 to 35 nm in diameter, possessed amorphous surface structure surrounded by fine projections and had a buoyant density of 1.36 to 1.37 g/ml in cesium chloride. Serological responses to the SRSV were found by immune electron microscopy and Western blot (WB) assay in paired sera of 12 of 19 patients. Furthermore, WB analysis revealed that the antibody against SRSV was cross-reactive to other SRSV, Tokyo 86/510.

    We present our reflections on the management of an acute gastroenteritis outbreak in a public school, which caused a public health crisis, and the conclusions drawn from this experience. The methodology of strengths, weaknesses, opportunities, and threats (SWOT) analysis was used. This article describes the epidemiology of the incident and the policy decisions made, but focuses on operational aspects of outbreak management. The experience of the outbreak control team, liaison with other organizations, and data management are discussed. The difficulties encountered by the outbreak team related to delay in declaring in the outbreak, lack of training in some of the entities involved, and incorrect use of the surveillance circuits. Current protocols and specific action plans for the management of outbreaks should be improved through self-evaluation and updating of resources and knowledge.

    Full Text Available In der Urologie hat die Zertrümmerung von schmerzhaften Nierensteinen mittels extrakorporaler Stoßwellen die nicht-invasive Therapie von Nierensteinen revolutioniert. Dieses erfolgversprechende Konzept wurde vor über 15 Jahren in der Orthopädie aufgegriffen. Dabei wurde versucht, die verzögerte Knochenbruchheilung durch Stimulation der Knochenenden mit Hilfe fokussierter extrakorporaler Stoßwellen zu beschleunigen. Im folgenden wurde dieses Verfahren erfolgreich zur Behandlung von Knochenbruchheilungsstörungen, der Tendinitis calcarea, der Epicondylitis radialis humeri und der Fasciitis plantaris eingesetzt. Dabei ist – anders als bei der Nierensteinzertrümmerung – nicht die Zerstörung von Hartgewebe für den Wirkmechanismus verantwortlich. Lange Zeit waren die Kenntnisse sowohl über die Wirkmechanismen extrakorporaler Stoßwellen am Knochen, als auch über mögliche unerwünschte Nebenwirkungen nur eingeschränkt verfügbar. In den letzten Jahren sind jedoch viele neue Studien publiziert worden. Die vorliegende Arbeit faßt den entsprechenden gegenwärtigen Kenntnisstand über die Wirkung extrakorporaler Stoßwellen auf den Knochen aus tier- und zellkulturexperimentellen Grundlagenuntersuchungen zusammen. Insbesondere in bezug auf mögliche unerwünschte Nebenwirkungen der ESWT haben die bisher durchgeführten Untersuchungen wertvolle Hinweise ergeben. Darüber hinaus konnten in jüngster Zeit erste Ergebnisse bezüglich der molekularen Wirkweise extrakorporaler Stoßwellen am Stütz- und Bewegungsapparat vorgelegt werden, die ein komplexes Bild der tatsächlichen Vorgänge erahnen lassen. Durch eine Intensivierung der tierexperimentellen Grundlagenforschung zur ESWT wird es möglich sein, in naher Zukunft eine breit abgesicherte, experimentell-wissenschaftliche Grundlage zum Einsatz extrakorporaler Stoßwellen am Stütz- und Bewegungsapparat zu erarbeiten.

    To examine (i) the extent of illness caused by contamination of a waterworks with waste water due to overflow, and its correlation with precipitation; (ii) the potential secondary spread; (iii) economic losses due to sick leave. A historical follow up study with structured postal questionnaires. A small community on the outskirts of greater Copenhagen at the end of 1991 and the beginning of 1992. The main study group comprised all 703 households supplied by the waterworks (response rate: 89% of households). There was a control group of 200 randomly chosen households in neighbouring communities with a different water supply source (response rate: 64% of households). A day care group of all 149 children (response rate: 78%) and 30 teachers (response rate: 83%) who lived in central Copenhagen, but spent the day in four day care centres supplied by the waterworks, and members of their household was also studied. Altogether 1455 people (88% of respondents in the main study group) reported having had symptoms of gastroenteritis, particularly diarrhoea (83%) and vomiting (55%). In the control group, 10% had had symptoms of gastroenteritis. The onset of episodes with diarrhoea correlated well with precipitation (Spearman's correlation coefficient: 0.75; p = 0.0002). The secondary attack rate in household contacts was 12%. No pathogens were found. Affected people stayed home from work for a total of 1658 days. The cost of loss of production because of sick leave amounted to 1,600,000 Danish kroner (180,000 pounds). The outbreak caused extensive illness correlated with precipitation, showed secondary spread, and was associated with major economic losses. Increased awareness among local physicians and waterworks personnel of the possibility of contamination of the water could have led to earlier intervention and reduced the extent of illness. Outbreaks are often caused by several factors, many of a technical nature, which in this case acted together. It is recommended that

    Full Text Available Abstract Background Rotavirus gastroenteritis (RVGE is the most common cause of severe childhood diarrhea worldwide. Objectives were to estimate the burden of RVGE among children less than five years old in the Middle East (Bahrain, Iran, Iraq, Israel, Jordan, Kuwait, Oman, Qatar, Saudi Arabia, Syria, UAE, Yemen, North Africa (Algeria, Egypt, Libya, Morocco, Tunisia and Turkey. Methods A comprehensive literature search was conducted in major databases on the epidemiology and burden of rotavirus among children less than five years old between 1999 and 2009. Data from each country was extracted and compared. Results The search identified 43 studies. RVGE was identified in 16-61% of all cases of acute gastroenteritis, with a peak in the winter. RVGE-related hospitalization rates ranged from 14% to 45%, compared to 14%-28% for non-RVGE. Annually, RVGE caused up to 112 fatalities per 100,000 in certain countries in the region. Hospitalization costs ranged from $1.8 to $4.6 million annually, depending on the country. The most recent literature available showed that G1P[8] was the most prevalent genotype combination in 8 countries (range 23%-56%. G2P[4] was most prevalent in 4 countries (26%-48%. G9P[8] and G4P[8] were also frequently detected. Conclusions RVGE is a common disease associated with significant morbidity, mortality, and economic burden. Given the variety and diverse rotavirus types in the region, use of a vaccine with broad and consistent serotype coverage would be important to help decrease the burden of RVGE in the Middle East and North Africa.

    The objective of the study is to determine the efficacy of oral granisetron (a long-acting 5-HT3 receptor antagonist) in stopping vomiting subsequent to discharge from emergency department (ED), in 6-month-old to 8-year-old patients with gastroenteritis-related vomiting and dehydration, who had failed an initial trial of oral rehydration (ORT). Eligible patients were offered ORT on a slowly advancing schedule. Patients who tolerated the initial ORT were discharged home. Patients who vomited were randomized to receive either 40 μg/kg of granisetron or placebo, and ORT was resumed. Patients who tolerated the postrandomization ORT were discharged home with another dose of the study drug. Parents were contacted by telephone every 24 hours until complete resolution of symptoms. The primary outcome was the proportion of patients with vomiting at 24 hours. Of the 900 eligible patients, 537 (60%) tolerated the initial ORT and were discharged home. Of the patients who vomited during the initial ORT, 165 were included in the final study sample (placebo, n = 82; granisetron, n = 83). There was no statistically significant difference in the proportion of patients with vomiting at 24 hours (granisetron, n = 38; placebo, n = 45; odds ratio, 0.64; 95% confidence interval, 0.34-1.19; P = .16). A similar trend in the proportion of patients with vomiting was noted for the entire follow-up period (granisetron, n = 43; placebo, n = 47; odds ratio, 0.73; P = .33; 95% confidence interval, 0.39-1.36). Granisetron was not effective in controlling gastroenteritis-related vomiting subsequent to discharge from ED. It did not change the expected course of the illness. Copyright © 2014 Elsevier Inc.

    Full Text Available Background: Livestock animals have been the assumed source of several human epidemics in recent years, for example, influenza H1N1, rotavirus G8/G9, and MERS-CoV. Surveillance of novel viruses in animals is essential to evaluate the risk to human and animal health and to determine any economic impact, for example, failure to thrive. There is a paucity of data regarding detection and characterisation of gastroenteritis viruses, particularly novel viruses, in porcines in Ireland. Recently, a number of small novel porcine DNA viruses have emerged globally, for example, torque teno sus virus, porcine bocavirus, and parvoviruses 2 & 4, and little is known about the biology and potential pathogenicity of these viruses. Bocaparvovirus is a genetically distinct group of viruses which has been recently detected in humans and animals. Methods: In this study, the presence of gastroenteritis viruses (rotavirus A, porcine circovirus, adenovirus, and porcine bocavirus was investigated in a selection of archived faecal samples from asymptomatic piglets from a commercial farm in Ireland. A total of 104 specimens were pooled and screened using conventional molecular techniques (PCR and RT-PCR, a subset of specimens (n=44 were then examined individually. Viral diversity was then investigated using statistical and phylogenetic techniques. Results: Initial screening showed a high prevalence of PBoV in this farm, with the formation of three distinct groups in phylogenetic analysis. Other viruses were also investigated in this study with the first report of PCV, PAdV and lineage I G5 RVA in Ireland. Some specimens contained >1 virus, with statistical analysis indicating a strong correlation for mixed infections of PBoV and PAdV on this farm. Conclusion: Investigating the diversity of circulating enteric viruses on Irish porcine farms is important to improve the prophylactic tools available and to facilitate the early detection of changes in circulating viruses.

    Acute gastroenteritis is characterized by diarrhea, which may be accompanied by nausea, vomiting, fever, and abdominal pain. To review the evidence on the assessment of dehydration, methods of rehydration, and the utility of antiemetics in the child presenting with acute gastroenteritis. The evidence suggests that the three most useful predictors of 5% or more dehydration are abnormal capillary refill, abnormal skin turgor, and abnormal respiratory pattern. Studies are conflicting on whether blood urea nitrogen (BUN) or BUN/creatinine ratio correlates with dehydration, but several studies found that low serum bicarbonate combined with certain clinical parameters predicts dehydration. In most studies, oral or nasogastric rehydration with an oral rehydration solution was equally efficacious as intravenous (i.v.) rehydration. Many experts discourage the routine use of antiemetics in young children. However, children receiving ondensetron are less likely to vomit, have greater oral intake, and are less likely to be treated by intravenous rehydration. Mean length of Emergency Department (ED) stay is also less, and very few serious side effects have been reported. In the ED, dehydration is evaluated by synthesizing the historical and physical examination, and obtaining laboratory data points in select patients. No single laboratory value has been found to be accurate in predicting the degree of dehydration and this is not routinely recommended. The evidence suggests that the majority of children with mild to moderate dehydration can be treated successfully with oral rehydration therapy. Ondansetron (orally or intravenously) may be effective in decreasing the rate of vomiting, improving the success rate of oral hydration, preventing the need for i.v. hydration, and preventing the need for hospital admission in those receiving i.v. hydration.

    Dehydration caused by acute rotavirus gastroenteritis is a frequent finding in pediatric patients. The most important treatment modality in these patients is recognising and treating dehydration, electrolyte imbalance and acute kidney injury. Neutrophil gelatinase-associated lipocalin (NGAL) is used widely as a biomarker for the diagnosis of acute or chronic renal injury in numerous clinical studies. It is recognized as an early marker of acute renal failure before the elevation of routine biochemical tests such as creatinine. The aim of this study is to investigate the plasma and urine NGAL concentrations in mildly or moderately dehydrated patients with acute rotavirus gastroenteritis. A total of 30 patients (13 girls, mean age 62.5 ± 46.2 months) with diarrhea and mild/moderate dehydration and 35 healthy controls (17 girls, mean age 81.1 ± 41.8 months) were enrolled in the study. Plasma and urine NGAL levels of the two groups were compared. The mean age, gender and serum creatinine levels of the patients and healthy controls were similar. The mean plasma and urine NGAL levels of the patients were significantly higher than controls (plasma: 118.6 ± 81.2 vs. 66.5 ± 11.3, p = 0.001 and urine: 17.7 ± 17.5 vs. 10.6 ± 7.9, p = 0.035, respectively). Mildly or moderately dehydrated children have higher plasma and urine NGAL levels compared to control subjects. Plasma and/or urine NGAL levels can be used for the early prediction of renal impairment in children with mild or moderate dehydration.

    We seek to determine whether an initial intravenous bolus of 5% dextrose in normal saline solution compared with normal saline solution will lead to a lower proportion of hospitalized patients and a greater reduction in serum ketone levels in children with gastroenteritis and dehydration. We enrolled children aged 6 months to 6 years in a double-blind, randomized controlled trial of patients presenting to a pediatric emergency department. Subjects were randomized to receive a 20 mL/kg infusion of either 5% dextrose in normal saline solution or normal saline solution. Serum ketone levels were measured before and at 1- and 2-hour intervals after the initial study fluid bolus administration. Primary outcome was the proportion of children hospitalized. Secondary outcome was change in serum ketone levels over time. One hundred eighty-eight children were enrolled. The proportion of children hospitalized did not differ between groups (35% in the 5% dextrose in normal saline solution group versus 44% in the normal saline solution group; risk difference 9%; 95% confidence interval [CI] -5% to 22%). Compared with children who received normal saline solution, those who received 5% dextrose in normal saline solution had a greater reduction in mean serum ketone levels at both 1 hour (mean Δ 1.2 versus 0.1 mmol/L; mean difference 1.1 mmol/L; 95% CI 0.4 to 1.9 mmol/L) and 2 hours (mean Δ 1.9 versus 0.3 mmol/L; mean difference 1.6 mmol/L; 95% CI 0.9 to 2.3 mmol/L). Administration of a dextrose-containing bolus compared with normal saline did not lead to a lower rate of hospitalization for children with gastroenteritis and dehydration. There was, however, a greater reduction in serum ketone levels in patients who received 5% dextrose in normal saline solution. Copyright © 2012. Published by Mosby, Inc.

    The aim of the study was to diagnose infections with rotavirus and other enteric pathogens in children under five years old with acute gastroenteritis and to identify the most common epidemiological and clinical characteristics of these pathogens. The study was conducted using 110 stool samples from the same number of children under five years old who were inpatients at three paediatric hospitals in Havana, Cuba, between October and December 2011. The samples were tested for rotavirus and other enteric pathogens using traditional and molecular microbiological methods. Pathogens were detected in 85 (77.3 %) of the children. Rotavirus was the most commonly found, appearing in 54.5 % of the children, followed by bacteria (29 %) and parasites (10.9 %). Other viral pathogens detected included adenovirus (6.4 %) and astrovirus (3.6 %). In rotavirus-positives cases, at least one other pathogen was detected, usually a bacterium (26.6 %). More than three episodes of watery diarrhea in 24 hours were observed in 78.3 % of the cases. Dehydration was found in 30 (50 %) rotavirus-positive children, of whom seven (11.6 %) were transferred to an intensive care unit due to complications of metabolic acidosis. Rotavirus was most commonly observed among children under 12 months old (65 %). The highest incidence of infection occurred in children who were under the care of a relative at home (78.3 %), had not been breastfed (65 %), or had been breastfed for less than six months (28.3 %). The genotype combinations most frequently found were G9P8 (28.3 %) and G1P8 (10 %). This study demonstrates the presence of rotavirus and other enteric pathogens as causes of gastroenteritis in hospitalized infants and young children in Cuba.

    Full Text Available Die radikale Prostatektomie ohne Nerverhalt geht mit Impotenz einher. Bei nerverhaltendem Vorgehen kann das Risiko der erektilen Dysfunktion gesenkt, aber nicht ausgeschlossen werden. Die präoperative Beratung der Patienten erfordert bei nerverhaltender Prostatektomie die Kenntnis der Faktoren, die Einfluss auf die postoperative Potenz haben. Patienten & Methoden: 110 Patienten antworteten 24 Monate nach radikaler perinealer nerverhaltender Prostatektomie auf einen per Post übermittelten Fragebogen. Die Patienten wurden, entsprechend dem Erection Hardness Score, nach der Rigidität ihrer Erektionen befragt. Überwiegend erfolgte der Nerverhalt unilateral (104/110.

    IMPORTANCE A genetic polymorphism affecting FUT2 secretor status in approximately one-quarter of humans of European descent affects the expression of histo-blood group antigens on the mucosal epithelia of human respiratory, genitourinary, and digestive tracts. These histo-blood group antigens serve as host receptor sites necessary for attachment and infection of some pathogens, including norovirus. OBJECTIVE We investigated whether an association exists between FUT2 secretor status and laboratory-confirmed rotavirus infections in US children. DESIGN, SETTING, AND PARTICIPANTS Multicenter case-control observational study involving active surveillance at 6 US pediatric medical institutions in the inpatient and emergency department clinical settings. We enrolled 1564 children younger than 5 years with acute gastroenteritis (diarrhea and/or vomiting) and 818 healthy controls frequency matched by age and month, from December 1, 2011, through March 31, 2013. MAIN OUTCOMES AND MEASURES Paired fecal-saliva specimens were tested for rotavirus and for secretor status. Comparisons were made between rotavirus test–positive cases and healthy controls stratified by ethnicity and vaccination status. Adjusted multivariable analyses assessed the preventive association of secretor status against severe rotavirus gastroenteritis. RESULTS One (0.5%) of 189 rotavirus test–positive cases was a nonsecretor, compared with 188 (23%) of 818 healthy control participants (P < .001). Healthy control participants of Hispanic ethnicity were significantly less likely to be nonsecretors (13%) compared with healthy children who were not of Hispanic ethnicity (25%) (P < .001). After controlling for vaccination and other factors, children with the nonsecretor FUT2 polymorphism appeared statistically protected (98% [95% CI, 84%–100%]) against severe rotavirus gastroenteritis. CONCLUSIONS AND RELEVANCE Severe rotavirus gastroenteritis was virtually absent among US children who had a genetic

    Shoulder instability is defined as a symptomatic abnormal motion of the humeral head relative to the glenoid during active shoulder motion. Glenohumeral instabilities are classified according to the causative factors as the pathogenesis of instability plays an important role with respect to treatment options. Instabilities are classified into traumatic and atraumatic instabilities as part of a multidirectional instability syndrome and into microtraumatic instabilities. For diagnostics plain radiographs (''trauma series'') are performed to document shoulder dislocation and its successful repositioning. Direct magnetic resonance (MR) arthrography is the most important imaging modality for delineation of the different injury patterns of the labral-ligamentous complex and bony structures. Monocontrast computed tomography (CT) arthrography with the use of multidetector CT scanners represents an alternative imaging modality; however, MR imaging should be preferred in the work-up of shoulder instabilities due to the mostly younger age of patients. (orig.) [German] Unter einer Schulterinstabilitaet versteht man jede zu Beschwerden fuehrende Translation des Humeruskopfs in Relation zur Gelenkpfanne waehrend einer aktiven Bewegung der Schulter. Glenohumerale Instabilitaeten werden heute nach ihrer Aetiologie eingeteilt, da bei der Wahl der Therapie der Entstehungsmechanismus der Instabilitaet eine wichtige Rolle spielt. Danach unterscheidet man primaer traumatisch von atraumatisch entstandenen Instabilitaeten sowie Mikroinstabilitaeten. Bei der Diagnostik dienen konventionelle Roentgenuebersichtsaufnahmen nur noch zur Dokumentation einer Luxation und zur Beurteilung der Reposition. Die durch eine Instabilitaet hervorgerufenen Verletzungsfolgen am labroligamentaeren Komplex und den knoechernen Strukturen werden heute bevorzugt mit der direkten MR-Arthrographie dargestellt.

Of the 284 specimens, 142 (50%) were found to be positive for viruses causing gastroenteritis. Rotavirus (66.2%) was the most frequently detected, followed by adenovirus (15.5%), norovirus and astrovirus each with 9.2%. All of rotavirus detected belonged to group A. Eight specimens were found positive by two viruses. The introduction of simple and rapid tests for diagnosis of viruses causing gastroenteritis in our pediatric hospitals will improve patient care by reducing unnecessary treatments and hospital stay for patients.

The decisive criterion defined by the BAG (Federal Labour Court) is the transfer of ownership of the essential operating equipment and the handing over of all business with customers, as the new owner of the facilities will use these for the same purpose as the former, namely to ensure and perform electricity supply. Application of paragraph 613 a BGB implies that the transferee, the local government utility, is obliged to take over the personnel employed at the time of takeover by the transferor either exclusively or overwhelmingly for the purpose of electricity distribution and supply in the given local supply area, regardless of their place of work.

Hat der Versöhnungsbegriff Hegels, der am konkretesten innerhalb des philosophischen Gedankens ausgeführt wird, bestimmte Folgen auch für den Begriff der Philosophie selber? Opfert sich die Philosophie einer endlichen Äußerlichkeit oder bedarf sie selbst eines Opfers, um das philosophische System als solches zu vervollständigen? Kann man auch heutzutage die geschichtlich-politischen Ereignisse und die Vergehen des Rechts als tragisch darstellen und betrachten? Vermag es die Politik noch immer (wie in der Moderne, die Rolle des Schicksals in der griechischen Tragödie zu übernehmen?

Verschiedene "Task Forces" arbeiten mit zum Teil identischen Methoden am gleichen Ziel. Die Bildung spezialisierter Endometriosezentren verbunden mit einer breiten Qualifikation der Ärzte und des medizinischen Personals gehören – begleitet von der Unterstützung der Forschung – ebenso in dieses Spektrum wie die Schulung und Information der betroffenen Frauen sowie die Sensibilisierung der Gesundheitspolitik, der Kostenträger und der Industrie. Vor dem Hintergrund knapper Ressourcen ist eine Bündelung des vorhandenen nationalen und internationalen Engagements absehbar und notwendig. Inwieweit dies zur konsequenten Gründung von einheitlichen nationalen Endometriose-Gruppen als Basis einer europäischen Dachgesellschaft führen könnte, bleibt abzuwarten.

    Rotavirus (RV)–specific secretory immunoglobulin (RV-SIg) has been previously detected in serum of naturally RV infected children and shown to reflect the intestinal Ig immune response. Total plasma SIgA and plasma RV-SIg were evaluated by ELISA in children with gastroenteritis due or not due to RV infection and in 50 children vaccinated with the attenuated RIX4414 human RV vaccine and 62 placebo recipients. RV-SIg was only detected in children with evidence of previous RV infection or with acute RV gastroenteritis. Vaccinees had higher RV-SIg titers than placebo recipients and RV-SIg titers increased after the second vaccine dose. RV-SIg measured after the second dose correlated with protection when vaccinees and placebo recipients were analyzed jointly. RV-SIg may serve as a valuable correlate of protection for RV vaccines.

    Various types of intestinal intussusception were diagnosed in 29 of 220 young dogs with acute enteritis or gastroenteritis, due to canine parvovirus (85 cases) or presumably to other infectious agents, inflammation or less common hypermotility and metabolic derangements (135 cases). As the other causes of the disease were excluded, acute enteritis or gastroenteritis was considered to be the most likely predisposing factor for the intestinal intussusception. The most common type of intussusception was found to be the ileocolic. Of the 21 dogs that underwent surgical resection and anastomosis of the intestine, 18 dogs recovered completely and three died due to complications. The high survival rate was due to the effective pre-operative, surgical and post-operative therapy.

    Rotavirus gastroenteritis (RVGE) results in substantial mortality and morbidity worldwide. However, an accurate estimation of the health and economic burden of RVGE in Malaysia covering public, private and home treatment is lacking. Data from multiple sources were used to estimate diarrheal mortality and morbidity according to health service utilization. The proportion of this burden attributable to rotavirus was estimated from a community-based study and a meta-analysis we conducted of primary hospital-based studies. Rotavirus incidence was determined by multiplying acute gastroenteritis incidence with estimates of the proportion of gastroenteritis attributable to rotavirus. The economic burden of rotavirus disease was estimated from the health systems and societal perspective. Annually, rotavirus results in 27 deaths, 31,000 hospitalizations, 41,000 outpatient visits and 145,000 episodes of home-treated gastroenteritis in Malaysia. We estimate an annual rotavirus incidence of 1 death per 100,000 children and 12 hospitalizations, 16 outpatient clinic visits and 57 home-treated episodes per 1000 children under-5 years. Annually, RVGE is estimated to cost US$ 34 million to the healthcare provider and US$ 50 million to society. Productivity loss contributes almost a third of costs to society. Publicly, privately and home-treated episodes consist of 52%, 27% and 21%, respectively, of the total societal costs. RVGE represents a considerable health and economic burden in Malaysia. Much of the burden lies in privately or home-treated episodes and is poorly captured in previous studies. This study provides vital information for future evaluation of cost-effectiveness, which are necessary for policy-making regarding universal vaccination.

Gleichzeitig stehen Bibliotheken im Lichte der Öffentlichkeit, was einen klaren und sicheren Umgang mit der Herkunft der Medien erfordert. Ist die Herkunft oder die Zuordnung der Medien nicht sicher oder erfolgte ein vorhergehender Erwerb durch eine Unrechtshandlung, so sollte über das Instrument der Provenienzforschung und nachgelagerter Handlungen ein sachgerechter Umgang erfolgen. Ein zentraler Wegbereiter für die Entwicklung der Provenienzforschung war und ist die Diskussion um die NS-Raubkunst. Ein weiterer Anlass ist die Entziehung von Kulturgütern in der SBZ bzw. DDR. Auch weniger spektakuläre Umstände – wie fehlende Unterlagen – lassen einen Nachforschungsbedarf entstehen. Der Beitrag beschäftigt sich aus juristischer Sicht mit der Provenienzforschung. The power of disposal over the library media is a basic requirement for libraries to offer their services. At the same time, libraries are in the public eye and need to treat the provenience of their media openly and reliably. If the history of a media item is unknown or the former acquisition was illegal, the issue should be properly handled by provenience research and subsequent actions. Provenience research has been pioneered by the discussion of the Nazi-looted art. Another catalyst for provenience research was the looted art in the Soviet Zone and German Democratic Republic. But also less spectacular circumstances like missing documentaries can make provenience research necessary. The present article covers provenience research from the legal point of view

We investigated the outbreak to identify the source, propose control and preventive measures. Materials and Methods: We defined a case of the gastroenteritis as the occurrence of more than three smelly loose motions between 28 th June to 2 nd July, 2006 among some sections of the resident hostellers. We determined age and sex specific attack rate. We hypothesized it as a food borne beef meat outbreak. We conducted the case control study and collected the information about the food items consumed inside and outside the hostel at dinner using the standardized questionnaire. We calculated floor wise incidences of four hostels, odds ratios and attributable fractions. We interviewed food handlers. We lifted the seven rectal stool, four water and three samples from floor, kitchen and meat chopper room for culture and sensitivity. Results: 116 cases patients of 802 hostellers met the case definition. The maximum attack rate (16% was in the youngest group (15-20yrs and nil in staff and 31-40 years age group with 5 overall attack rate as 14%. Sex specific attack rate was more (18% in females.

    Purpose Rotavirus (RV) is a leading cause of severe gastroenteritis (GE) in children across the world. As there is a lack of epidemiological data for RV gastroenteritis (RVGE) in Saudi Arabia, this hospital-based study was designed to estimate the disease burden of RVGE and assess the prevalent RV types in Saudi children younger than 5 years of age. Patients and methods Children hospitalized for acute GE were enrolled at four pediatric referral hospitals in Saudi Arabia. The study was conducted from February 2007 to March 2008 and used the World Health Organization’s generic protocol for RVGE surveillance. The Vesikari severity scale was used to assess the severity of RVGE. Stool samples were tested for RV using an enzyme-linked immunosorbent assay. Samples were further typed by reverse transcriptase–polymerase chain reaction and hybridization assay for determining the G and P types. Results A total of 1,007 children were enrolled; the final analysis included 970 children, of whom 395 were RV positive, 568 were RV negative, and seven had unknown RV status. The proportion of RVGE among GE hospitalizations was 40.7% (95% confidence interval: 37.6–43.9). The highest percentage of RVGE hospitalizations (83.1%) was seen in children younger than 2 years of age. The highest proportion of RV among GE hospitalizations was in June 2007 with 57.1%. The most common RV types detected were G1P[8] (49.3%), G1G9P[8] (13.2%), and G9P[8] (9.6%). Before hospitalization, severe GE episodes occurred in 88.1% RV-positive and 79.6% RV-negative children. Overall, 94% children had recovered by the time they were discharged. Two children (one RV positive and one RV negative) died due to GE complications. Conclusion RVGE is responsible for a high proportion of hospitalizations in Saudi children younger than 5 years of age. Routine RV vaccination has therefore been introduced into the national immunization program and may help reduce the morbidity, mortality, and disease burden

    To characterize the prevalence of rotavirus (RV) and adenovirus (AdV) infections in immunocompromised patients with acute gastroenteritis. The presence of RV and AdV (serotypes 40 and 41) was evaluated in 509 stool samples obtained between January 2009 and December 2010 from 200 immunocompromised patients (83 females and 117 males; median age 21 years old, range 0-72. The diagnosis of infection was performed as a routine procedure and the presence of RV and AdV (serotypes 40 and 41) was determined by immunochromatography using the RIDA(®) Quick Rota-Adeno-Kombi kit (r-Biopharm, Darmstadt, Germany). The data analysis and description of seasonal frequencies were performed using computer software IBM(®) SPSS(®) (Statistical Package for Social Sciences) Statistics version 20.0 for Mac. The frequencies of infection were compared into different age and gender groups by χ(2) test. The study revealed 12.4% AdV positive samples and 0.8% RV positive samples, which correspond to a prevalence of 6.5% and 1.5%, respectively. AdV was more frequent between October 2009 and April 2010, while RV was identified in April 2010 and July 2010. The stool analysis revealed that from the 509 samples, 63 (12.4%) were positive for AdV and 4 (0.8%) positive for RV, which by resuming the information of each patient, lead to an overall prevalence of AdV and RV of 6.5% (13/200 patients) and 1.5% (3/200 patients), respectively. The stratification of the analysis regarding age groups showed a tendency to an increased prevalence of infection in paediatric patients between 0-10 years old. Considering the seasonal distribution of these infections, our study revealed that AdV infection was more frequent between October 2009 and April 2010, while RV infection was characterized by two distinct peaks (April 2010 and July 2010). The overall prevalence of AdV and RV infection in immunocompromised patients with acute gastroenteritis was 8% and AdV was the most prevalent agent.

Results For 12% of the GP patients with gastroenteritis, a stool sample was requested and tested for enteric pathogens. In most patients, the duration, followed by severity of complaints or a visit to a specific, high-risk country were reported as reasons to request laboratory diagnostics. Tests were requested most often in summer months and in February. Campylobacter (requested for 87% of the tests, Salmonella (84%, Shigella (78% and Yersinia (56% were most frequently included in the stool tests. Campylobacter was detected most often in patients. Conclusion Test requests did not always comply with existing knowledge of the etiology of gastroenteritis in GP patients and were not always consistent with the Dutch GP guidelines. Therefore, the data of this study can be used to develop educational approaches for GP's as well as for revision of the guidelines.

    Full Text Available Salmonella is considered to be one of the main pathogens causing human gastroenteritis worldwide. Looking for Salmonella in Africa in patients suffering from gastroenteritis is rather unusual, and the use of antibiotics is not subject to any regulation. This study intends for stressing the possible prominent importance of Salmonella in digestive diseases in Africa as well as identifying antimicrobial resistance of Salmonella isolates from faeces samples of human origin. All samples were collected from five N'Djamena hospitals, from patients suffering from diarrhoea. The collecting was undertaken over two periods of six months each: from August 2010 to January 2011 and from September 2011 to February 2012. Salmonella isolates were obtained by standard cultivation and serotyping methods. A total of 43 Salmonella isolates were identified, belonging to 21 different serovars. The most prevalent serovar was Salmonella Stanleyville (n = 7, followed by S. Anatum (n = 4 and S. Kottbus (n = 3. The other serovars were under-represented. The majority of these isolates were susceptible to all antibiotics tested (CLSI Standards, except two S. Enteritidis isolates that exhibited resistance to fluoroquinolones. The different serovars and antibiotic resistance profiles that were observed highlight the substantial diversity of Salmonella in N'Djamena, Chad. Roughly, one out of ten patients who consulted for gastroenteritis was shedding Salmonella spp. and none of them would have been diagnosed outside the context of this research program. This study may encourage local clinicians to explore more often salmonellosis suspicion in their daily practice.

    SUMMARY On 6 December 2010 a fire in Hemiksem, Belgium, was extinguished by the fire brigade with both river water and tap water. Local physicians were asked to report all cases of gastroenteritis. We conducted a retrospective cohort study among 1000 randomly selected households. We performed a statistical and geospatial analysis. Human stool samples, tap water and river water were tested for pathogens. Of the 1185 persons living in the 528 responding households, 222 (18·7%) reported symptoms of gastroenteritis during the time period 6-13 December. Drinking tap water was significantly associated with an increased risk for gastroenteritis (relative risk 3·67, 95% confidence interval 2·86-4·70) as was place of residence. Campylobacter sp. (2/56), norovirus GI and GII (11/56), rotavirus (1/56) and Giardia lamblia (3/56) were detected in stool samples. Tap water samples tested positive for faecal indicator bacteria and protozoa. The results support the hypothesis that a point-source contamination of the tap water with river water was the cause of the multi-pathogen waterborne outbreak.

    Mainzer, K.

    Seit der Antike wird der Aufbau des Universums mit einfachen und regulären (symmetrischen) Grundstrukturen verbunden. Diese Annahme liegt selbst noch den Standardmodellen der relativistischen Kosmologie zugrunde. Demgegenüber läßt sich die Emergenz neuer Strukturen von den Elementarteilchen über Moleküle bis zu den komplexen Systemen des Lebens als Symmetriebrechung verstehen. Symmetriebrechung und strukturelle Komplexität bestimmen die kosmische Evolution. Damit zeichnet sich ein fachübergreifendes Forschungsprogramm von Physik, Chemie und Biologie ab, in dem die Evolution des Universums untersucht werden kann.

    Full Text Available In der beruflichen Bildung sind (E-Portfolios zur Reflexion des Gelernten – anders als etwa an Hochschulen oder in allgemeinbildenden Schulen – in Theorie und Praxis gegenwärtig kaum existent. Konzepte und Studien zum Einsatz von E-Portfolios in der Berufsausbildung und der Weiterbildung fehlen weitgehend, so dass die Potenziale von Portfolioarbeit für eine selbstbewusstere und selbstbestimmtere Gestaltung beruflichen Lernens bisher ungenutzt bleiben. Hier setzt dieser Beitrag an. Es wird ein Konzept vorgestellt, wie der Einsatz eines E-Portfolios die Berufsausbildung im dualen System unterstützen kann. Anhand des dargestellten Beispiels werden Möglichkeiten und Grenzen des Einsatzes von E-Portfolios in der beruflichen Bildung aufgezeigt. Die Umsetzung des E-Portfolios findet im Rahmen des berufswissenschaftlich begründeten E- Learning-Konzepts der Kompetenzwerkst@tt statt (vgl. Howe/Knutzen 2007. Die Kompetenzwerkst@tt ist ein softwaregestütztes Ausbildungskonzept, das sich an realen beruflichen Arbeitsprozessen und Ansätzen des Situierten Lernens orientiert. Im Mittelpunkt des E-Portfolios als Teil der Kompetenzwerkst@tt steht die lernortübergreifende Dokumentation und Reflexion der Ausbildungsinhalte der Dualen Berufsausbildung. Im Beitrag wird gezeigt, wie die konzeptionellen Überlegungen zur Portfolioarbeit in der beruflichen Bildung vom Portfolio-Diskurs in anderen Bildungsbereichen beeinflusst sind, sich aber in der Umsetzung und in den konkreten Zielsetzungen deutlich unterscheiden. Es werden darüber hinaus weitere Möglichkeiten und Optionen von Portfolioarbeit in der beruflichen Bildung aufgezeigt.

    Vertically stacked van der Waals heterostructures are a lucrative platform for exploring the rich electronic and optoelectronic phenomena in two-dimensional materials. Their performance will be strongly affected by impurities and defects at the interfaces. Here we present the first systematic study of interfaces in van der Waals heterostructure using cross-sectional scanning transmission electron microscope (STEM) imaging. By measuring interlayer separations and comparing these to density functional theory (DFT) calculations we find that pristine interfaces exist between hBN and MoS 2 or WS 2 for stacks prepared by mechanical exfoliation in air. However, for two technologically important transition metal dichalcogenide (TMDC) systems, MoSe 2 and WSe 2 , our measurement of interlayer separations provide the first evidence for impurity species being trapped at buried interfaces with hBN interfaces that are flat at the nanometer length scale. While decreasing the thickness of encapsulated WSe 2 from bulk to monolayer we see a systematic increase in the interlayer separation. We attribute these differences to the thinnest TMDC flakes being flexible and hence able to deform mechanically around a sparse population of protruding interfacial impurities. We show that the air sensitive two-dimensional (2D) crystal NbSe 2 can be fabricated into heterostructures with pristine interfaces by processing in an inert-gas environment. Finally we find that adopting glovebox transfer significantly improves the quality of interfaces for WSe 2 compared to processing in air.

  16. Vaccine preventable viral diseases and risks associated with waterborne transmission

    Directory of Open Access Journals (Sweden)

    Franco Maria Ruggeri

    2012-12-01

    Full Text Available Rotavirus and poliovirus are paradigmatic viruses for causing major diseases affecting the human population. The impact of poliovirus is remarkably diminished because of vaccination during the last half century. Poliomyelitis due to wild polio currently affects a limited number of countries, and since 2000 sporadic outbreaks have been associated to neurovirulent vaccine-derived polioviruses. Conversely, rotavirus is presently very diffuse, accounting for the largest fraction of severe gastroenteritis among children <5 years-old. Vaccination towards rotavirus is still in its dawn, and zoonotic strains contribute to the emergence and evolution of novel strains pathogenic to man. The environment, particularly surface water, is a possible vehicle for large transmission of both viruses, but environmental surveillance of circulating strains can help promptly monitor entry of new virulent strains into a country, their shedding and spread.

    Full Text Available Zweck dieser Untersuchung war es, die Effizienz von Transitionalzonenbiopsien und von Biopsien der lateralen Anteile der Prostata zur Karzinomentdeckung zu untersuchen, nachdem eine vorangegangene Biopsie keinen Tumor finden konnte. Methodik: Wir untersuchten 74 Präparate nach radikaler Prostatektomie und unterzogen diese einer sonographisch gezielten Prostatabiopsie ex vivo. Zuerst erfolgte eine Sextantenbiopsie, dann zwei unterschiedliche Rebiopsien. Rebiopsie-Technik A bestand aus einer lateral plazierten Sextantenbiopsie und zwei Stanzen aus den Transitionalzonen je Seite. Rebiopsie-Technik B bestand aus einer Sextantenbiopsie und zwei Stanzen je Seite aus den lateralen Arealen der Prostata. Ergebnisse: Mit der initialen Sextantenbiopsie konnten 39 Karzinome gefunden werden (53 %. Von den verbliebenen Karzinomen konnten mit der Rebiopsie-Technik A 12 Karzinome gefunden werden. In dieser Gruppe fand eine lateral durchgeführte Sextantenbiopsie 12 Karzinome. Die Transitionalzonenbiopsien waren in 5 Fällen positiv, jedoch konnte kein zusätzlicher Tumor entdeckt werden. Mit der Rebiopsie-Technik B wurden 23 Karzinome gefunden. 14 Tumore enthielten die Stanzen der Sextantenbiopsie. Zusätzliche 9 Tumore waren in den Stanzen aus den lateralen Arealen der Prostata enthalten. Schlußfolgerungen: Eine Standard-Sextantenbiopsie hat eine niedrige Sensitivität von nur 53 %. Eine Biopsie, welche die Transitionalzonen inkludiert, ist nicht geeignet, die verbliebenen Karzinome zu finden. In dieser Studie zeigte die Wiederholung einer Sextantenbiopsie mit zusätzlichen Stanzen aus den lateralen Arealen das beste Ergebnis bei der Rebiopsie.

    Full Text Available Allgemeines: Schon seit langem wird die Frage einer Beteiligung des Hypophysenhormons Human Growth Hormone (Wachstumshormon, hGH, GH an der Kontrolle der sexuellen Maturation und der Reproduktionsfunktion des Menschen diskutiert. Die Symptome eines GH-Defizits beim Mann sind u. a. allgemeine Antriebslosigkeit, Oligo- oder Azoospermie, eine Verminderung der Libido sowie eine Beeinträchtigung der normalen Erektionsfähigkeit. Es wird vermutet, daß die biologischen Effekte des GH eine durch das Somatomedin Insulin-like Growth Factor 1 (IGF-1 vermittelte Stimulation der Produktion von Stickoxid (NO durch die endotheliale und neuronale Form des Enzyms NO-Synthase einschließen. So konnte gezeigt werden, daß physiologische Konzentrationen von GH den adrenergen Tonus isolierter Streifenpräparate humaner Schwellkörpermuskulatur antagonisieren und den Gewebegehalt des Second Messengers cGMP erhöhen. Im Rahmen dieser Studie haben wir in einem Kollektiv gesunder Männer und in einer Gruppe von Patienten mit erektiler Dysfunktion (ED die systemischen und cavernösen Serumkonzentrationen von GH während verschiedener peniler Funktionszustände, d. h. verschiedener Stadien der sexuellen Erregung, untersucht.

    A cross-border gastroenteritis outbreak at a scouting camp was associated with drinking water from a farmer's well. A retrospective cohort study was performed to identify size and source of the outbreak, as well as other characteristics. Epidemiological investigation included standardized questionnaires about sex, age, risk exposures, illness and family members. Stool and water (100mL) samples were analyzed for bacteria, viruses and parasites. Questionnaires were returned by 84 scouts (response rate 82%), mean age of 13 years. The primary attack rate was 85% (diarrhoea and/or vomiting). Drinking water was the strongest independent risk factor showing a dose-response effect with 50%, 75%, 75%, 93% and 96% case prevalence for 0, 1, 2-3, 4-5 and >5 glasses consumed, respectively. Norovirus (GI.2 Southampton and GII.7 Leeds) was detected in 51 stool specimens (75%) from ill scouts. Water analysis showed fecal contamination, but no norovirus. The secondary attack rate was 20%. This remarkable outbreak was caused by a point-source infection with two genogroups of noroviruses most likely transmitted by drinking water from a well. Finding a dose-response relationship was striking. Specific measures to reduce the risk of waterborne diseases, outbreak investigation and a good international public health network are important.

    On May 21, 1997, numerous cases of febrile gastrointestinal illness were reported among the students and staff of two primary schools in northern Italy, all of whom had eaten at cafeterias served by the same caterer. We interviewed people who ate at the cafeterias about symptoms and foods consumed on May 20. There were no samples of foods left at the cafeterias, but we tested routine samples taken on May 20 by the caterer and environmental specimens at the catering plant. The hospitalized patients were tested for common enteropathogens and toxins. Of the 2189 persons interviewed (82 percent of those exposed), 1566 (72 percent) reported symptoms; of these, 292 (19 percent) were hospitalized. Among samples obtained from hospitalized patients, all but two of the stool specimens and all blood specimens were negative for common enteropathogens. Listeria monocytogenes was isolated from one blood specimen and from 123 of the 141 stool specimens. Consumption of a cold salad of corn and tuna was associated with the development of symptoms (relative risk, 6.19; 95 percent confidence interval, 4.81 to 7.98; Pcaterer's sample of the salad and from environmental specimens collected from the catering plant. All listeria isolates were serotype 4b and were found to be identical on DNA analysis. Experimental contamination of sterile samples of the implicated foods showed that L. monocytogenes grew on corn when kept for at least 10 hours at 25 degrees C. Food-borne infection with L. monocytogenes can cause febrile illness with gastroenteritis in immunocompetent persons.

    In February 2000, an outbreak of gastroenteritis occurred among employees of a car dealership in New York. The same meal was also supplied to 52 dealerships nationwide, and 13 states reported illness at dealerships where the banquet was served. A retrospective cohort study was conducted to identify risk factors associated with the illness. Stool samples were collected to detect Norwalk-like virus, and sera were drawn and tested for immunoglobulin A antibodies to the outbreak strain. By univariate analysis, illness was significantly associated with consumption of any of four salads served at the banquet (relative risk = 3.8, 95% confidence interval: 2.5, 5.6). Norwalk-like virus was detected by reverse transcription-polymerase chain reaction assay in 32 of 59 stool samples from eight states. Nucleotide sequences of a 213-base pair fragment from 16 stool specimens collected from cases in eight states were identical, confirming a common source outbreak. Two of 15 workers at caterer A had elevated immunoglobulin A titers to an antigenically related Norwalk-like virus strain. This study highlights the value of molecular techniques to complement classic epidemiologic methods in outbreak investigations and underscores the critical role of food handlers in the spread of foodborne disease associated with Norwalk-like virus.

    In Amsterdam, 17 of the 55 gastroenteritis (GI) outbreaks reported from January 2002 to May 2003 were confirmed to be caused by noroviruses (NV). In this study, we describe the molecular epidemiology of a group of nine outbreaks associated with a catering firm and two outbreaks, 5 months apart, in an Amsterdam hospital. All outbreaks were typed to confirm their linkage, and the hospital-related cases were studied to see if the two outbreaks were caused by one persisting NV strain or by a reintroduction after 5 months. For the outbreaks associated with the catering firm one NV genogroup I strain was found which was identical in sequence among customers and employees of the caterer. This was not the strain that predominantly circulated in 2002/2003 in and around Amsterdam, which was the NV genogroup II4 "new variant" (GgII4nv) strain. In the Amsterdam hospital, the two outbreaks were caused by this predominant GgII4nv type, and we argue that NV was most likely reintroduced in the second outbreak from the Amsterdam community.

    From 20 September through 5 October 2012, the largest recorded food-borne outbreak in Germany occurred. Norovirus was identified as the causative agent. We conducted four analytical epidemiological studies, two case–control studies and two surveys (in total 150 cases) in secondary schools in three different federal states. Overall, 390 institutions in five federal states reported nearly 11,000 cases of gastroenteritis. They were predominantly schools and childcare facilities and were supplied almost exclusively by one large catering company. The analytical epidemiological studies consistently identified dishes containing strawberries as the most likely vehicle, with estimated odds ratios ranging from 2.6 to 45.4. The dishes had been prepared in different regional kitchens of the catering company and were served in the schools two days before the peaks of the respective outbreaks. All affected institutions had received strawberries of one lot, imported frozen from China. The outbreak vehicle was identified within a week, which led to a timely recall and prevented more than half of the lot from reaching the consumer. This outbreak exemplifies the risk of large outbreaks in the era of global food trade. It underlines the importance of timely surveillance and epidemiological outbreak investigations for food safety.

    Full Text Available A two month study to investigate the incidence o f nosocomial infection was conducted in a paediatric gastroenteritis ward o f a black academic hospital. Enteric pathogens were identified on admission in 61 (47,2% o f 129 patients; 56 bacterial and 25 viral. Six per cent o f patients had a combination o f bacterial and viral pathogens. Enteric pathogens most frequently identified on admission were Campylobacter jejuni in 22%, Rotavirus in 19,3%, EPEC in 10,8% and Shigella spp. in 6,9% patients. Twenty six (20% patients had more than 1 enteric pathogen. The nosocomial infection rate was recorded at 17,1%. EPEC occurred most commonly in 5,3% patients, Salmonella typhimurium in 4,6% and Shigella spp. in 2,3%. Nosocomial infections increased the mean length o f hospital stay from 7,2- 20,2 days. Contributory factors to the spread o f nosocomial infection were the unsatisfactory methods o f bathing patients and giving naso-gastric feeds.

    Full Text Available Aim: Hemorrhagic gastroenteritis (HGE ranging from mild to severe forms is commonly encountered in puppies. The aim of the study was to identify the prevalence of common enteropathogens and the antibiotic sensitivity pattern in puppies reported with HGE. Materials and Methods: The canine HGE activity index, with little modification, was adopted to identify Grade III/ severely affected puppies below 6 months of age. Fecal polymerase chain reaction (PCR assay was employed to screen and compare the enteropathogens in puppies with hemorrhagic diarrhea and healthy control. Results: Canine parvovirus 2b was identified in 90.3% of the diarrheic and 10% of the non-diarrheic healthy puppies. Clostridium difficile was identified in all the diarrheic puppies and in 80% of the healthy puppies. Among the diarrheic puppies, 17.7% were positive for Clostridium perfringens enterotoxin, 9.7% were positive for C. perfringens alpha toxin, 6.4% were positive for Escherichia coli shiga toxin, 6.4% were positive for E. coli enterotoxin (LT, and 3.2% were positive for canine distemper virus. Whereas, none of the healthy puppies were positive for these bacteria and toxins. Fecal antibiotic sensitivity test pattern revealed gentamicin to be sensitive in 95% of the cases, azithromycin in 50%, enrofloxacin in 25%, cefotaxime in 20%, and tetracycline in 5% of the cases. Conclusion: Parvoviral enteritis is predominant among puppies. Yet, bacteria and their toxins also play an important role in HGE. Gentamicin has higher sensitivity against the enteropathogens associated with the condition.

    An inappropriate cross-connection between sewage- and drinking-water pipelines contaminated tap water in a Finnish town, resulting in an extensive waterborne gastroenteritis outbreak in this developed country. According to a database and a line-list, altogether 1222 subjects sought medical care as a result of this exposure. Seven pathogens were found in patient samples of those who sought treatment. To establish the true disease burden from this exposure, we undertook a population-based questionnaire investigation with a control population, infrequently used to study waterborne outbreaks. The study covered three areas, contaminated and uncontaminated parts of the town and a control town. An estimated 8453 residents fell ill during the outbreak, the excess number of illnesses being 6501. Attack rates were 53% [95% confidence interval (CI) 49.5-56.4] in the contaminated area, 15.6% (95% CI 13.1-18.5) in the uncontaminated area and 6.5% (95% CI 4.8-8.8) in the control population. Using a control population allowed us to differentiate baseline morbidity from the observed morbidity caused by the water contamination, thus enabling a more accurate estimate of the disease burden of this outbreak.

    Two outbreaks of non-bacterial gastroenteritis occurred in Gifu prefecture in January 1989 and in January 1991. Both outbreaks were closely related to the consumption of raw oysters, and showed similar clinical features. Small, round-structured virus particles were found in patient stools in both outbreaks by electron microscopy. The role of these particles as the causative agents of the outbreaks were strongly suggested by immune electron microscopy and/or western-blotting immunoassay. When compared with SRSV-9 (Tokyo/SRSV/86-510) reported previously (Hayashi et al, J. Clin. Microbiol., 27: 1728-1733, 1989), it was found that these viral particles were antigenically similar to SRSV-9, and had a major structural protein of 63 kilodaltons (kDa). Further, the prevalence of this agent in Gifu area was examined by western blot antibody assay using 67 serum samples collected from the inhabitants in 1991. The results indicated the circulation of the same or antigenically similar agent in this area.

    An investigation, in Ciudad Quesada of Costa Rica, has been carried out to explore and characterize the outbreak of acute gastroenteritis in the area. Surveillance data and medical records of the patients were analyzed to develop a descriptive study between July 8 and July 14, 2010 in the canton of San Carlos. A fact sheet was applied to obtain information from patients. ELISA test was performed to the stool samples to detect the presence of enteropathogens. Water samples were analyzed for bacteria and fecal coliform in the distribution system. A total of 352 cases were confirmed in the studied region. The most frequent symptoms among confirmed cases were: diarrhea (94,2%), nausea (92,7%) and vomiting (91,7%). The average age of patients is 29 years (15,8%) and (50,8%) has been female. The age group that has been most affected are infants of 1-4 years (attack rate 18,2/1,000 population). The area that has been most affected is the central area of Ciudad Quesada. In five out of six stool tests has been possible to isolate the norovirus. In water Escherichia coli has been witnessed by what has been suggested that the norovirus has been transmitted by water contaminated with fecal matter. Water quality monitoring has been recommended and promote the use of potable water as well as the sensitization of rural communities about hygiene and disease prevention. (author) [es

    Rotavirus is a major cause of gastroenteritis in children. Knowledge of rotavirus genotypes is important for vaccination strategies. During 2005-2006, rotavirus surveillance studies were conducted in São Paulo, Salvador, Goiânia, and Porto Alegre, Brazil. Stool samples were collected from children <5 years of age who had diarrhea and were screened by the Rotaclone Enzyme Immunoassay for the presence of rotavirus. Confirmed rotavirus-positive samples were characterized for P and G genotypes by reverse-transcriptase polymerase chain reaction. A total of 510 stool samples were collected. Of these, 221 (43.3%) were positive for rotavirus. Overall, G9 was the predominant G type, followed by G2, and G1; P[4] and P[8] were the predominant P types. The most frequent G/P genotype combination detected was G2P[4], followed by G9P[8], G9P[4], and G1P[8]. G2P[4] was the predominant type in Goiânia and Salvador; G9P[8] and G1P[8] were predominant in São Paulo and Porto Alegre, respectively. The prevalence, seasonality, and genotype distribution of rotavirus infection varied in different regions in Brazil. With immunization programs, continuous monitoring of rotavirus types is important to detect novel and emerging strains.

    2012-01-01

    Full Text Available Abdominal pain, bloating, early satiety, and changes in bowel habits are common presenting symptoms in individuals with functional GI disorders. Emerging data suggests that these symptoms may be associated with mast cell excess and/or mast cell instability in the GI tract. The aim of this retrospective study was to evaluate the contribution of mast cells to the aforementioned symptoms in individuals with a history of atopic disease. A retrospective chart review of individuals seen in a university GI practice was conducted and twenty-four subjects were identified. The majority had abdominal pain, early satiety, and nocturnal awakening. 66.7% and 37.5% had a history of environmental and/or food allergy. Solid gastric emptying was increased as were the mean number of mast cells reported on biopsies from the stomach, small bowel, and colon (>37/hpf by CD117 staining. Mean whole blood histamine levels were uniformly elevated. This study suggests that in individuals with these characteristics, consideration should be given to staining their gastrointestinal biopsies for mast cells as this may provide them with relatively non-toxic but highly targeted treatment options. Allergic gastroenteritis and colitis may represent a third type of GI mast cell disorder along with mast cell activation syndrome and mastocytic enterocolitis.

    Gastroenteritis (GE) causes significant morbidity, especially in young children. A vaccine against rotavirus, a common cause of viral GE (vGE), was added to the childhood immunization schedule in the UK in July 2013 and further related vaccines are under development. To explore parents' beliefs about vGE and their attitudes towards vaccinating. Qualitative interview study with parents of children who had recently experienced an episode of GE. Twenty-eight semi-structured interviews were conducted over the phone with parents. Interviews were audio-recorded, transcribed and analysed using standard thematic approaches. Parents varied in their perception of the threat posed by GE, and parents who did not perceive GE as serious were less enthusiastic about vaccines. Other parents were supportive of vaccines in general and considered benefits to their child, their family and the wider community. Many parents said that they lacked knowledge about efficacy and effectiveness of GE vaccines but their underlying belief about the seriousness of illness motivated their attitudes. Acceptability of GE vaccines to parents could be improved by providing more information on both the burden of illness and the impact of rotavirus vaccine in other comparable countries. © The Author 2015.

    Rising numbers of campylobacteriosis case notifications in Switzerland resulted in an increased attention to acute gastroenteritis (AG) in general. Patients with a laboratory-confirmed Campylobacter infection perceive their disease as severe and around 15% of these patients are hospitalized. This study aimed at estimating healthcare costs due to AG and campylobacteriosis in Switzerland. We used official health statistics, data from different studies and expert opinion for estimating individual treatment costs for patients with different illness severity and for extrapolating overall costs due to AG and campylobacteriosis. We estimated that total Swiss healthcare costs resulting from these diseases amount to €29-45 million annually. Data suggest that patients with AG consulting a physician without a stool diagnostic test account for €9·0-24·2 million, patients with a negative stool test result for Campylobacter spp. for €12·3 million, patients testing positive for Campylobacter spp. for €1·8 million and hospitalized campylobacteriosis patients for €6·5 million/year. Healthcare costs of campylobacteriosis are high and most likely increasing in Switzerland considering that campylobacteriosis case notifications steadily increased in the past decade. Costs and potential cost savings for the healthcare system should be considered when designing sectorial and cross-sectorial interventions to reduce the burden of human campylobacteriosis in Switzerland.

    Eosinophilic gastroenteritis (EG) is an uncommon disease characterized by focal or diffuse eosinophilic infiltration of the gastrointestinal tract, and is usually associated with dyspepsia, diarrhea and peripheral eosinophilia. Diffuse gastrointestinal tract and colonic involvement are uncommon. The endoscopic appearance may vary from normal to mucosal nodularity and ulceration. Gastrointestinal obstruction is unusual and is associated with predominantly muscular disease. We present five unusual cases of EG associated with gastric outlet and duodenal obstruction. Two cases presented with acute pancreatitis and one had a history of pancreatitis. Four cases responded well to medical therapy and one had recurrent gastric outlet obstruction that required surgery. Four out of the five cases had endoscopic and histological evidence of esophagitis and two had colitis. Two patients had ascites. These cases reaffirm that EG is a disorder with protean manifestations and may involve the entire gastrointestinal tract. Gastric outlet and/or small bowel obstruction is an important though uncommon presentation of EG. It may also present as esophagitis, gastritis with polypoid lesions, ulcers or erosions, colitis and pancreatitis and may mimic malignancy.

    Full Text Available Despite substantial interventions in the understanding and case management of acute gastroenteritis, diarrheal diseases are still responsible for a notable amount of childhood deaths. Although the rotavirus is known to cause a considerable burden of pediatric diarrheal cases, the roles of other viruses remain undefined for the Pakistani population. This study was based on tertiary care hospital surveillance, from January 2009 to December 2010, including the detection of rotavirus, norovirus, astrovirus, and human parechovirus in children under the age of five using serological or molecular assays. Rotavirus, human parechovirus, norovirus, and astrovirus were detected in 66%, 21%, 19.5%, and 8.5% subjects, respectively. Human parechovirus genotypes, determined through analysis of VP1 gene sequences, showed a great diversity among co-circulating strains. Eighty percent of hospitalized children had dual or multiple viral infections, while 98% parechovirus positive cases were co-infected with rotavirus. The remarkable diversity of viruses associated with the childhood diarrhea in Pakistan calls for large-scale epidemiological surveys, coupled with case control studies, to ascertain their role in clinical manifestations. In addition, these findings also highlight the need for the implementation of up-to-date health interventions, such as the inclusion of a rotavirus vaccine in routine immunization programs for the improvement of quality in child health care.

    Non-steroidal anti-inflammatory drugs (NSAIDs) induce acute kidney injury (AKI) in volume-depleted patients; however the prevalence of this complication is likely underestimated. We assessed the impact of ibuprofen exposure on renal function among dehydrated children with acute gastroenteritis (AGE) to further characterize NSAID-associated AKI. Over a 1-year period dehydrated children with AGE (n = 105) were prospectively enrolled and grouped as cases, presenting with AKI (n = 46) or controls, not presenting with AKI (n = 59). AKI was defined by pediatric RIFLE (pRIFLE) criteria. Among the children enrolled in the study, AKI prevalence was 44 %, and 34 (54 %) of the 63 patients who received ibuprofen developed renal impairment. Relative to the controls, children presenting with AKI were younger (median age 0.66 vs. 1.74 years; p dehydration, ibuprofen exposure remained an independent risk factor for AKI (p dehydrated children with AGE. Drug exposure increased the risk for developing AKI by more than twofold, independent of the magnitude of the dehydration.

    We compared rotavirus detection rates in children with acute gastroenteritis (AGE) and in healthy controls using enzyme immunoassays (EIAs) and semiquantitative real-time reverse transcription PCR (qRT-PCR). We calculated rotavirus vaccine effectiveness using different laboratory-based case definitions to determine which best identified the proportion of disease that was vaccine preventable. Of 648 AGE patients, 158 (24%) were EIA positive, and 157 were also qRT-PCR positive. An additional 65 (10%) were qRT-PCR positive but EIA negative. Of 500 healthy controls, 1 was EIA positive and 24 (5%) were qRT-PCR positive. Rotavirus vaccine was highly effective (84% [95% CI 71%–91%]) in EIA-positive children but offered no significant protection (14% [95% CI −105% to 64%]) in EIA-negative children for whom virus was detected by qRT-PCR alone. Children with rotavirus detected by qRT-PCR but not by EIA were not protected by vaccination, suggesting that rotavirus detected by qRT-PCR alone might not be causally associated with AGE in all patients.

    Poliovirus (PV) is typically transmitted by the fecal-oral route, which means that the risk of infection and virus distribution could be achieved by exposure to the virus contaminated in food and water. The aim of this study was to determine the occurrence of PV strains by detecting the virus in pediatric patients who admitted to the hospitals with diarrhea in Chiang Mai, Thailand during 2010-2015. By applying a reverse transcription-polymerase chain reaction and nucleotide sequencing analysis of 1,300 stool specimens collected from pediatric patients, PVs were detected at 0.61% (8 out of 1,300 specimens). Among eight PV positive samples, mixed infection with norovirus or human bocavirus was detected in one each out of eight cases. All PV strains detected in this study were characterized further by phylogenetic analysis of 343 bp of the 5' UTR and 315 bp of the partial VP1 sequences. The results revealed that eight PV strains detected in the present study two of each were PV1 and PV2, and four were PV3 serotypes of the Sabin vaccine strains. The data demonstrated the presence of PV1, PV2, and PV3 Sabin vaccine strains in children with acute gastroenteritis in Chiang Mai, Thailand. J. Med.

    Vibrio vulnificus is a virulent human pathogen causing gastroenteritis and possibly life threatening septicemia in patients. Most V. vulnificus are catalase positive and can deactivate peroxides, thus allowing them to survive within the host. In the study presented here, a catalase from V. vulnificus (CAT-Vv) was purified to homogeneity after expression in Escherichia coli. The kinetics and function of CAT-Vv were examined. CAT-Vv catalyzed the reduction of H 2 O 2 at an optimal pH of 7.5 and temperature of 35°C. The V max and K m values were 65.8±1.2 U/mg and 10.5±0.7 mM for H 2 O 2 , respectively. Mutational analysis suggests that amino acids involved in heme binding play a key role in the catalysis. Quantitative reverse transcription-PCR revealed that in V. vulnificus, transcription of CAT-Vv was upregulated by low salinity, heat, and oxidative stresses. This research gives new clues to help inhibit the growth of, and infection by V. vulnificus.

    Rotavirus is recognized to be a very important cause of GE in younger children in both developed as well as developing countries, but causes most of the mortality and morbidity in the latter. The recent introduction of a rotavirus vaccine in some parts of the world makes it necessary for us to determine the impact of this organism in our population with the aim of determining the need for the vaccine. In order to determine this, a study was conducted at the JUH and 3 other private hospitals. At the JUH, 64/256 (25%) of children with GE had rotavirus in 1995. The proportions of cases attributed to rotavirus in the other 3 y were 70/199 (35.2%), 69/279 (24.7%) and 76/294 (25.8%) for 2002, 2003 and 2004, respectively. The cumulative proportion of cases attributable to rotavirus gastroenteritis in all the y was 27.14%. With regard to the 3 private hospitals, rotavirus accounted for 38/225 (16.9%), 140/664 (21%) and 668/1496 (44.6%) at the Khalidy, Jordan and Islamic hospitals, respectively. It is concluded that rotavirus is a significant cause of GE in Jordanian children regardless of their social background, and attempt at controlling this infection may be warranted.

    Acute gastroenteritis (AGE) is one of the most common diseases among children and an important cause of school absenteeism. The aim of this study was to assess the effectiveness of a handwashing program using hand sanitizers for the prevention of school absenteeism due to AGE. A randomized, controlled and open study of a sample of 1341 children between 4 and 12 years of age, attending 5 state schools in Almería (Spain), with an 8-month follow up (academic year). The experimental group (EG) washed their hands with soap and water, complementing this with the use of a hand sanitizer, and the control group (CG) followed the usual handwashing procedure. Absenteeism rates due GI were compared between the 2 groups through the multivariate Poisson regression analysis. Percent days absent in both groups were compared with a Z-test. 446 cases of school absenteeism due to AGE were registered. The school children from the EG had a 36% lower risk of absenteeism due to AGE (IRR: 0.64, 95% confidence interval: 0.52-0.78) and a decrease in absenteeism of 0.13 episodes/child/academic year (0.27 of EG vs 0.40 CG/episodes/child/academic year, P absenteeism cases due to AGE.

    Eosinophilic gastroenteritis, focal or diffuse with eosinophilic infiltrations of the stomach or intestine, has been described in human beings, cats, dogs, and horses. In this paper, we describe infiltration of the gastrointestinal tract with eosinophils accompanied by a circulating eosinophilia in six ferrets (Mustela putorius furo). Clinical signs included chronic weight loss, anorexia, and diarrhea. The small intestines from five ferrets had diffuse infiltrates of eosinophils. This resulted in focal or multifocal loss of the muscular tunic in three ferrets. Two of these ferrets also had eosinophilic gastritis. Eosinophilic granulomas with Splendore-Hoeppli material were present in mesenteric lymph nodes in four ferrets. Two ferrets had multiple organ involvement; one had eosinophilic granulomas in the liver, mesentery, and choroid plexus as well as moderate parapancreatic segmental arteritis with infiltration of eosinophils and mural thrombosis. The second ferret had, in addition to moderate diffuse gastric and small intestinal eosinophilic mucosal infiltrations, interstitial eosinophilic pulmonary infiltrates. Examination of all tissues failed to reveal an infectious agent.
