    Full Text Available Abstract Background In West Africa, the Northern Sahelian zone and the coastal areas are densely populated but the Middle Belt in between is in general sparsely settled. Predictions of climate change foresee more frequent drought in the north and more frequent flooding in the coastal areas, while conditions in the Middle Belt will remain moderate. Consequently, the Middle Belt might become a major area for immigration but there may be constraining factors as well, particularly with respect to water availability. As a case study, the paper looks into the capacity of the Middle Belt zone of Benin, known as the Oueme River Basin (ORB, to reduce diarrhea prevalence. In Benin it links to the Millennium Development Goals on child mortality and environmental sustainability that are currently farthest from realization. However, diarrhea prevalence is only in part due to lack of availability of drinking water from a safe source. Social factors such as hygienic practices and poor sanitation are also at play. Furthermore, we consider these factors to possess the properties of a local public good that suffers from under provision and requires collective action, as individual actions to prevent illness are bound to fail as long as others free ride. Methods Combining data from the Demographic Health Survey with various spatial data sets for Benin, we apply mixed effect logit regression to arrive at a spatially explicit assessment of geographical and social determinants of diarrhea prevalence. Starting from an analysis of these factors separately at national level, we identify relevant proxies at household level, estimate a function with geo-referenced independent variables and apply it to evaluate the costs and impacts of improving access to good water in the basin. Results First, the study confirms the well established stylized fact on the causes of diarrhea that a household with access to clean water and with good hygienic practices will, irrespective of

    Full Text Available Clostridium difficile is a frequently identified cause of nosocomial gastrointestinal disease. It has been proved to be a causative agent in antibiotic-associated diarrhea, antibiotic-associated colitis, and pseudomembraneous colitis. This study was aimed to determine the prevalence of C.difficile- associated diarrhea in hospitalized patients with nosocomial diarrhea. The 942 hospitalized patients stool samples with nosocomial diarrhea were collected at three hospitals in Tehran from Dec 2002 to Feb 2004.All the stool samples were cultured and in 97 (prevalence: 10.9% samples grew C.difficile that 57 (prevalence: 6.1% isolates were toxigenic by cytotoxicity assay and so 57 patients had C.difficile- associated diarrhea. Results of statistical analysis showed significant difference between the rate of C.difficile associated diarrhea and the patients ages (P<0.05.

    Full Text Available Abstract Background There is a high incidence of diarrhea in traveling populations. Norovirus (NV infection is a common cause of diarrhea and is associated with 7% of all diarrhea related deaths in the US. However, data on the overall prevalence of NV infection in traveling populations is limited. Furthermore, the prevalence of NV amongst travelers returning to Europe has not been reported. This study determined the prevalence of NV among international travelers returning to Germany from over 50 destinations in and outside Europe. Methods Stool samples of a total of 104 patients with a recent ( Results In our cohort, NV infection was detected in 15.7% of returning travelers with diarrhea. The closer to the date of return symptoms appeared, the higher the incidence of NV, ranging as high as 21.2% within the first four days after return. Conclusions In our cohort, NV infection was shown to be frequent among returning travelers especially in those with diarrhea, with over 1/5 of diarrhea patients tested positive for NV within the first four days after their return to Germany. Due to this prevalence, routine testing for NV infection and hygienic precautions may be warranted in this group. This is especially applicable to patients at an increased risk of spreading the disease, such as healthcare workers, teachers or food-handlers.

    Care practices and risk factors for diarrhea among impoverished communities across Mesoamerica are unknown. Using Salud Mesoamérica Initiative baseline data, collected 2011-2013, we assessed the prevalence of diarrhea, adherence to evidence-based treatment guidelines, and potential diarrhea correlates in poor and indigenous communities across Mesoamerica. This study surveyed 14,500 children under 5 years of age in poor areas of El Salvador, Guatemala, Mexico (Chiapas State), Nicaragua, and Panama. We compared diarrhea prevalence and treatment modalities using χ(2) tests and used multivariable Poisson regression models to calculate adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) for potential correlates of diarrhea. The 2-week point prevalence of diarrhea was 13% overall, with significant differences between countries (P < 0.05). Approximately one-third of diarrheal children were given oral rehydration solution and less than 3% were given zinc. Approximately 18% were given much less to drink than usual or nothing to drink at all. Antimotility medication was given to 17% of diarrheal children, while antibiotics were inappropriately given to 36%. In a multivariable regression model, compared with children 0-5 months, those 6-23 months had a 49% increased risk for diarrhea (aRR = 1.49, 95% CI = 1.15, 1.95). Our results call for programs to examine and remedy low adherence to evidence-based treatment guidelines. PMID:26787152

    Full Text Available Iron deficiency anemia is still common in children under five years of age and may impair their growth and cognitive development. Diarrhea is the second most common reason for seeking medical care for young children in Nepal. However, neither screening programs nor effective preventive measures for anemia and iron deficiencies are in place among children with diarrhea in many developing countries. The aims of this study were to determine the prevalence of anemia and iron deficiency and explore their associations with clinical, socioeconomic, and anthropometric parameters in Nepalese children. This was a cross-sectional study based on 1232 children, six to 35 months old, with acute diarrhea participating in a zinc supplementation trial. The mean (SD hemoglobin was 11.2 g/dL (1.2. Anemia was found in 493 children (40%; this estimate increased to 641 (52% when we adjusted for the altitude of the study area (hemoglobin <11.3 g/dL. One in every three children had depleted iron stores and 198 (16% of the children had both depleted iron stores and anemia, indicating iron deficiency anemia. The prevalence of anemia among children presenting with acute diarrhea was high but the degree of severity was mainly mild or moderate. Iron deficiency explained less than half of the total anemia, indicating other nutritional deficiencies inducing anemia might be common in this population.

    To examine the relationship between measures of mother's caretaking, practice and individual agency on acute diarrhea and respiratory tract infections (ARTIs) of Indonesian children. Using population-based household data from the Indonesian Demographic Health Surveys for 2002-2003 (n = 9,151 children) and 2007 (n = 9,714 children), we selected 28 indicators related to mother' caretaking, and applied principal component analysis to derive indices for access to care, practice and experience, and agency. The association between index quartiles (level 1-4) and the prevalence of diarrhea and ARTIs in the youngest child family size, child's age and sex, immunization status and received vitamin A supplementation. Moderate levels (level 3) of practice and experience were associated with decreased diarrheal risk (adjusted OR 0.86, 95 % CI 0.75-0.98), but not for ARTIs. Children of mothers with higher levels (level 4) of agency were protected against both diarrhea (adjusted OR 0.68, 95 % CI 0.60-0.77) and ARTIs (adjusted OR 0.77, 95 % CI 0.66-0.91). Stratified analyses with child's age and mother's education, and tests of interaction, showed that agency had a stronger effect on diarrhea and ARTIs prevalence in children child health.

    2010-09-01

    Full Text Available Abstract Background Rotavirus remains the commonest cause of severe dehydrating diarrhea among children worldwide. Children in developing countries die more because of several factors including poorer access to hydration therapy and greater prevalence of malnutrition. Hitherto, the magnitude of rotavirus disease in Uganda has remained unknown. This study was therefore done to determine the prevalence and factors associated with rotavirus infection among children aged 3-59 months admitted with acute diarrhea to paediatric emergency ward of Mulago Hospital, Uganda Methods Three hundred and ninety children, aged between 3-59 months with acute diarrhoea were recruited. The clinical history, socio-demographic characteristics, physical examination findings and laboratory investigations were recorded. Stool samples were tested for rotavirus antigens using the DAKO IDEIA rotavirus EIA detection kit. Results The prevalence of rotavirus infection was 45.4%. On multivariate analysis rotavirus was significantly associated with a higher education (above secondary level of the mother [OR 1.8; 95% CI 1.1-2.7]; dehydration [OR 1.8; 95% CI 1.1-3.0] and breastfeeding [OR 2.6; 95% CI 1.4-4.0]. Although age was significantly associated with rotavirus on bivariate analysis; this association disappeared on multivariate analysis. No significant association was found between rotavirus infection and nutritional status, HIV status and attendance of day care or school. Conclusions Rotavirus infection is highly prevalent among children with acute diarrhoea admitted to Mulago Hospital in Uganda.

    Enteric viruses are a major cause of diarrhea in children, especially those under five years old. Identifying the viral agents is critical to the development of effective preventive measures. This study aimed to determine the prevalence and genetic diversity of common enteric viruses in children under five years old in Burkina Faso. Stool samples from children with (n = 263) and without (n = 50) diarrhea disorders were collected in Ouagadougou, Burkina Faso from November 2011 to September 2012. Rotavirus, norovirus, sapovirus, astrovirus, adenovirus and Aichivirus A were detected using real-time or end-point (RT-)PCR. Rotavirus strains were G and P genotyped by multiplex RT-PCR and other viral strains were characterized by sequencing of viral subgenomic segements. At least one viral agent was detected in 85.6% and 72% of the symptomatic and asymptomatic patients, respectively. Rotavirus (63.5%), adenovirus (31.2%) and genogroup II norovirus (18.2%) were the most prevalent viruses in symptomatic patients, but only rotavirus and genogroup II norovirus were significantly associated with diarrhea (OR: 7.9, 95%CI: 3.7-17; OR: 3.5, 95%CI: 1-11.7, respectively). Sapovirus (10.3%), astrovirus (4.9%), genogroup I norovirus (2.7%) and Aichivirus A (0.8%) were less prevalent. The predominant genotype of rotavirus was G9P[8] (36.5%), and the predominant norovirus strain was GII.4 variant 2012 (71.4%). Among sapovirus, the genogroup II (87.5%) predominated. Astrovirus type 1 (41.7%) was the most frequent astrovirus identified. Aichivirus A belonged to the three genotypes (A, B and C). Enteric adenoviruses type 40 and 41 were identified in 10.2% and 5.1% respectively. Several cases of co-infections were detected. The results highlight the high prevalence and the high diversity of enteric viruses in Burkinabe children. PMID:27092779

  18. Prevalence of microscopic colitis in patients with diarrhea of unknown etiology in Turkey

    2008-01-01

    AIM: To investigate the prevalence and demography of microscopic colitis in patients with diarrhea of unknown etiology and normal colonoscopy in Turkey. METHODS: Between March, 1998 to July, 2005, 129 patients with chronic non-bloody diarrhea of unexplained etiology who had undergone full colonoscopy with no obvious abnormalities were included in the study. Two biopsies were obtained from all colonic segments and terminal ileum for diagnosis of microscopic colitis. On histopathologic examination, criteria for lymphocytic colitis (intraepithelial lymphocyte ≥ 20 per 100 intercryptal epithelial cells, change in surface epithelium, mononuclear infiltration of the lamina propria) and collagenous colitis (subepithelial collagen band thickness ≥ 10 μm) were explored. RESULTS: Lymphocytic colitis was diagnosed in 12 (9%) patients (Female/Male: 7/5, mean age: 45 year, range: 27-63) and collagenous colitis was diagnosed in only 3 (2.5%) patients (all female, mean age: 60 years, range: 54-65). CONCLUSION: Biopsy of Turkish patients with the diagnosis of chronic non-bloody diarrhea of unexplained etiology and normal colonoscopic findings will reveal microscopic colitis in approximately 10% of the patients. Lymphocytic colitis is 4 times more frequent than collagenous colitis in these patients

    Norovirus infections in diarrhea patients attending an urban and a rural hospital in Bangladesh were investigated. A total of 953 fecal specimens from both children and adults collected during 2010-2014 were tested for the presence of norovirus using real time PCR. One fourth (25%) of the specimens were positive for norovirus RNA which was identified both in children and adults. Norovirus was associated with short duration of diarrhea, high abdominal pain, and more moderate to severe dehydration when compared with rotavirus infections. Norovirus GII (69%) was the most prevalent genogroup followed by GI (18%), mixed GI/GII/GIV (11%), and GIV (2%). Among GII genogroup, GII.4 (42%) was the most prevalent genotype followed by GII.3 (21%), GII.6 (7%), GII.7 (6%), and GII.21 (6%). GII.4 and GII.3 strains were frequently identified (82% and 75%, respectively) in children <2 years of age and less commonly (16% and 15%) in adults more than 18 years of age. The present study reinforces the importance of norovirus-associated hospitalizations both in children and adults. The dynamic molecular epidemiology of norovirus requires routine strain surveillance to identify changes in prevailing strains. J. Med. Virol. 88:1742-1750, 2016. © 2016 Wiley Periodicals, Inc.

    2016-01-01

    Full Text Available Introduction & Objective: Diarrhea is the most common cause of morbidity and mortality in all age groups, especially children, the elderly and immunocompromised patients. Various studies have been reported regarding the relationship between the children acute diarrhea and Aeromonashydrophila and Yersinia enterocolitica. This study aimed to investigate the prevalence of the bacteria and their sensitivity to common antibiotics and the prevalence of virulence genes in the bacteria in Hamadan, Iran. Materials & Methods: In this study, 120 stool samples collected from children less than 10 years of age with acute diarrhea were examined for Aeromonashydrophila and Yersinia enterocolitica. Identification of the bacteria was performed by biochemical reactions and PCR using 16S rRNA genes. Moreover, the prevalence of virulence genes earA and hyl of Aeromonashydrophila and ail and ystB genes of Yersinia enterocolitica were investigated using PCR. Antibiotic susceptibility of isolated bacteria was performed by disk diffusion method. Results: Out of 120 stool samples, 2 (1.7 % Aeromonashydrophila and 3 (2.5% Yersinia enterocolitica were isolated. All isolates of Aeromonashydrophila were sensitive to the chloramphenicol, co-trimoxazole, gentamicin, meropenem, amikacin and 50% of isolates were sensitive to the ceftriaxone and azithromycin. All Aeromonashydrophila isolates were resistant to erythromycin. All isolates of Yersinia enterocolitica were sensitive to the chloramphenicol, co-trimoxazole and meropenem. The 33.3% of the isolates were sensitive to gentamicin and amikacin and 66.6% of them were susceptible to ceftriaxone. However, all of Yersinia enterocolitica isolates were resistant to erythromycin and azithromycin. The prevalence aerA and hyl genes in Aeromonashydrophila were reported 100% and 50%, respectively. The prevalence of ail and ystB genes in Yersinia enterocolitica was reported as 66.6%. Conclusions: Identification and analysis of

  2. A molecular study on the prevalence and virulence potential of Aeromonas spp. recovered from patients suffering from diarrhea in Israel.

    Yigal Senderovich

    Full Text Available BACKGROUND: Species of the genus Aeromonas are native inhabitants of aquatic environments and have recently been considered emerging human pathogens. Although the gastrointestinal tract is by far the most common anatomic site from which aeromonads are recovered, their role as etiologic agents of bacterial diarrhea is still disputed. Aeromonas-associated diarrhea is a phenomenon occurring worldwide; however, the exact prevalence of Aeromonas infections on a global scale is unknown. METHODOLOGY/PRINCIPAL FINDINGS: The prevalence and virulence potential of Aeromonas in patients suffering from diarrhea in Israel was studied using molecular methods. 1,033 diarrheal stools were sampled between April and September 2010 and Aeromonas species were identified in 17 (∼2% patients by sequencing the rpoD gene. Aeromonas species identity and abundance was: A. caviae (65%, A. veronii (29% and Aeromonas taiwanensis (6%. This is the first clinical record of A. taiwanensis as a diarrheal causative since its recent discovery from a wound infection in a patient in Taiwan. Most of the patients (77% from which Aeromonas species were isolated were negative for any other pathogens. The patients ranged from 1 to 92 years in age. Aeromonas isolates were found to possess different virulence-associated genes: ahpB (88%, pla/lip/lipH3/apl-1 (71%, act/hlyA/aerA (35%, alt (18%, ast (6%, fla (65%, lafA (41%, TTSS ascV (12%, TTSS ascF-ascG (12%, TTSS-dependent ADP-ribosylating toxins aexU (41% and aexT (6% in various combinations. Most of the identified strains were resistant to beta-lactam antibiotics but susceptible to third-generation cephalosporin antibiotics. CONCLUSIONS: Aeromonas may be a causative agent of diarrhea in patients in Israel and therefore should be included in routine bacteriological screenings.

    Full Text Available CONTEXT: Acute diarrhea is a common cause of hospitalization among children under 5 years of age. Knowing the prevalence and risk factors associated with the severity of acute diarrhea is essential to control morbidity and mortality. OBJECTIVE: Describe the prevalence of demographic, epidemiologic and clinical features of children under 6 years of age hospitalized for acute diarrhea, and investigate the association between these determinants and the severity of the diarrheic episode. METHOD: Retrospective, cross-sectional study, during the period from January, 2005 through December, 2008, in the municipality of Juiz de Fora, MG, Brazil. Files from 6,201 children from 0 to 6 years of age, hospitalized in two public teaching institutions (which account for 84% of all the hospitalizations in the municipality, were assessed. Acute diarrhea was defined as the presence of at least three evacuations of liquid or loose stools, within 24 hours, for a maximum period of 14 days. The patients with acute diarrhea were divided in two groups, according to disease severity, severe diarrhea being considered whenever hospitalization lasted for at least 4 days. Epidemiologic and clinical data were assessed and compared through the application of the chi-squared test and the binomial logistic regression model. RESULTS: The prevalence rate for admission due to acute diarrhea was 8.4%. The factors significantly associated with the severity of the diarrheic episode were: age under 6 months (P = 0.01, OR = 2.762; disease onset during fall (P = 0.033, OR = 1.742, presence of fever (P = 0.017, OR = 1.715 and antibiotic use during hospitalization (P = 0.000, OR = 3.872. CONCLUSIONS: Diarrhea is the third most common cause of hospitalization among children under 6 years of age in Juiz de Fora. Young age (under or equal to 6 months, fever, antibiotic use during hospitalization and disease onset during fall are risk factors associated with longer hospital stay.

    Full Text Available Abstract Background Different groups of viruses have been shown to be responsible for acute diarrhea among children during their first few years of life. Epidemiological knowledge of viral agents is critical for the development of effective preventive measures, including vaccines. Methods In this study we determined the prevalence of the four major enteropathogenic viruses – rotavirus, norovirus, adenovirus and astrovirus – was determined in 270 stool samples collected from children aged 0 – 60 months who were admitted with diarrhea in four hospitals in Dar es Salaam, Tanzania, using commercially available ELISA kits. In addition, the molecular epidemiology of group A rotavirus was investigated using reverse transcriptase multiplex polymerase chain reaction (RT-PCR. Results At least one viral agent was detected in 87/270 (32.2% of the children. The prevalence of rotavirus, norovirus, adenovirus and astrovirus was 18.1%, 13.7%, 2.6% and 0.4%, respectively. In most cases (62.1% of viruses were detected in children aged 7–12 months. The G and P types (VP7 and VP4 genotypes respectively were further investigated in 49 rotavirus ELISA positive samples. G9 was the predominant G type (81.6%, followed by G1 (10.2% and G3 (0.2%. P[8] was the predominant P type (83.7%, followed by P[6] (0.4% and P[4] (0.2%. The following G and P types were not detected in this study population; G2, G4, G8 G10, P[9], P[10] and P[11]. The dominating G/P combination was G9P[8], accounting for 39 (90.7% of the 43 fully characterized strains. Three (6.1% of the 49 rotavirus strains could not be typed. Conclusion Nearly one third of children with diarrhea admitted to hospitals in Dar es Salaam had one of the four viral agents. The predominance of rotavirus serotype G9 may have implication for rotavirus vaccination in Tanzania.

    2014-12-01

    Clostridium perfringens has been suspected as an enteropathogen in dogs. However, its exact role in gastrointestinal (GI) disorders in dogs remains unknown. Recent studies suggest the importance of an altered intestinal microbiota in the activation of virulence factors of enteropathogens. The aim of this study was to evaluate the relationship between diarrhea, dysbiosis, and the presence of C. perfringens and its enterotoxin (CPE). Fecal samples were collected prospectively from 95 healthy control dogs and 104 dogs with GI disease and assessed for bacterial abundances and the presence of CPE using quantitative PCR and ELISA, respectively. C. perfringens was detected in all dogs. Potentially enterotoxigenic C. perfringens were detected in 33.7% (32/95) of healthy control dogs and 48.1% (50/104) diseased dogs, respectively. CPE was detected by ELISA in 1.0% (1/95) of control dogs and 16.3% (17/104) of diseased dogs. Abundances of Fusobacteria, Ruminococcaceae, Blautia, and Faecalibacterium were significantly decreased in diseased dogs, while abundances of Bifidobacterium, Lactobacillus, and Escherichia coli were significantly increased compared to control dogs. The microbial dysbiosis was independent of the presence of the enterotoxigenic C. perfringens or CPE. In conclusion, the presence of CPE as well as fecal dysbiosis was associated with GI disease. However, the presence of C. perfringens was not indicative of GI disease in all cases of diarrhea, and the observed increased abundance of enterotoxigenic C. perfringens may be part of intestinal dysbiosis occurring in GI disease. The significance of an intestinal dysbiosis in dogs with GI disease deserves further attention. PMID:25458422

    In the present study, we examined the prevalence of Providencia spp. in retail meats and in stool samples from diarrheal patients in Thailand. Providencia-specific (Psp)-PCR amplification was positive for 58% (15/26) of the chicken, 64% (16/25) of the pork, and 68% (17/25) of the beef samples. Subsequently, Providencia strains were isolated from 65% (17/26) of the chicken, 68% (17/25) of the pork, and 72% (18/25) of the beef samples. Although P. alcalifaciens (40-58%) was the most prevalent Providencia strain, P. rettgeri, P. stuartii, and P. rustigianii were also isolated. Of the patient stool samples tested, 7.5% (16/214) had Psp-PCR products, of which 4 were P. alcalifaciens (1.9%), 4 were P. rettgeri (1.9%), and 1 was P. stuartii (0.5%). In conclusion, retail meats were substantially contaminated with Providencia, especially P. alcalifaciens. Therefore, retail meats are possibly the source of Providencia infections in humans.

    2016-01-01

    Serological surveys based on a planned sampling on bovine viral diarrhea virus (BVDV) infection in Brazilian cattle herds are scarce. A cross-sectional study was carried out to determine herd- and animal-level seroprevalences and to identify risk factors associated with herd-level seroprevalence for BVDV infection in the State of Paraíba, Northeastern Brazil, from September 2012 to January 2013. The state was divided into three sampling strata, and for each stratum, the prevalence of herds infected with BVDV and the prevalence of seropositive animals was estimated by a two-stage sampling survey. In total, 2443 animals were sampled from 478 herds. A virus-neutralization test was used for BVDV antibody detection. A herd was considered positive when at least one seropositive animal was detected. The herd- and animal-level prevalences in the State of Paraíba were 65.5% (95% confidence interval (CI) = 61.1-69.7%) and 39.1% (95% CI = 33.1-45.6%), respectively. The frequency of seropositive animals per herd ranged from 10 to 100% (median of 50%). The risk factors identified were as follows: more than six calves aged ≤12 months (odds ratio (OR) = 3.72; 95% CI = 2.08-6.66), animal purchasing (OR = 1.66; 95% CI = 1.08-2.55), pasture rental (OR = 2.15; 95% CI = 1.35-3.55), and presence of veterinary assistance (OR = 2.04; 95% CI = 1.10-3.79). Our findings suggest that the implementation of control and prevention measures among farmers, with the aim of preventing dissemination of the agent in the herds, is necessary. Special attention should be given to addressing the identified risk factors, such as sanitary control prior to animal purchasing and to discourage the pasture rental, as well as to encourage the vaccination in the herds.

  15. Studies of the prevalence and significance of radiolabeled bile acid malabsorption in a group of patients with idiopathic chronic diarrhea

    We studied radiolabeled fecal bile acid excretion in 11 normal subjects and 17 patients with idiopathic chronic diarrhea for three major purposes: to establish normal values for this test in the presence of increased stool volumes (induced in normal subjects by ingestion of poorly absorbable solutions); to test for bile acid malabsorption in the patients and to correlate this with an independent test of ileal function, the Schilling test; and to compare the results of the bile acid excretion test with the subsequent effect of a bile acid binding agent (cholestyramine) on stool weight. In normal subjects fecal excretion of the radiolabel was increased with increasing stool volumes. As a group, patients with idiopathic chronic diarrhea excreted radiolabeled bile acid more rapidly than normal subjects with induced diarrhea (t1/2 56 +/- 8 vs. 236 +/- 60 h, respectively, p less than 0.005). There was a statistically significant positive correlation between t1/2 of radiolabeled bile acid and Schilling test results in these patients. Although 14 of 17 patients absorbed labeled taurocholic acid less well than any of the normal subjects with comparable volumes of induced diarrhea, cholestyramine had no statistically significant effect on stool weight in the patient group, and in none of the patients was stool weight reduced to within the normal range. In summary, most patients with idiopathic chronic diarrhea have bile acid malabsorption (as measured by fecal excretion of labeled bile acid), but they do not respond to cholestyramine therapy with a significant reduction in stool weight. Although the significance of these findings was not clearly established, the most likely interpretation is that bile acid malabsorption is a manifestation of an underlying intestinal motility or absorptive defect rather than the primary cause of diarrhea

    Full Text Available Diarrheal diseases can be caused by viral, bacterial and parasitic infections. This paper provides a preliminary image of diarrhea with regards to etiology and epidemiologic factors in Tunisian children less than five years of age.Overall, 124 diarrhoeal stools were collected from patients suffering from acute diarrhea and 54 stool samples from healthy children. All stools were examined for the presence of enteric pathogens.In diarrheagenic children, 107 pathogenic bacteria were isolated (12 Salmonella spp. (9.7% and 95 diarrheagenic Escherichia coli strains (76.6%: 29 enteroaggregative E.coli (EAEC (23.4%, 15 enteroinvasive E.coli (EIEC (12.1%, 17 enteropathogenic E.coli (EPEC (13.7%, 26 enterotoxigenic E.coli (ETEC (21% and 2 enterohemoragic E.coli (EHEC (1.6%. However, in the control group, 23 pathogenic E.coli strains were isolated (42.6%: 8 EAEC (14.8%, 12 EIEC (22.2% and 3 EPEC (5.5%. Among diarrheagenic E.coli (DEC, only ETEC strains were significantly recovered from diarrheagenic children than from healthy controls (P < 0.0003. Group A rotavirus was identified in 33.9% (n=42 of diarrheagenic children and in 11.1% among the control group (n=6. Concerning norovirus, 8.9% (n=11 of the samples collected from diarrheagenic children and 9.2% (n=5 from the control group were positive. The prevalence of rotaviruses and Salmonella spp were also significantly higher in patients with diarrhea than in controls (P = 0.002 and P < 0.019, respectively. Finally, enteropathogenic parasites (Entamoeba coli and cryptosporidium Oocystes were isolated from 4.8% and 9.2% of diarrheagenic and control children, respectively.These results provide baseline data about the relative importance of different enteropathogens in Tunisian children.

    2012-01-01

    The prevalence of Campylobacter spp. was investigated in 327 patients suffering from diarrhea and in 36 animals (dogs, cats and chickens) owned by the patients that presented infection by Campylobacter in Santa Rosa, La Pampa, Argentina. Campylobacter spp. was isolated in 50/327 patients and in 12/36 animals, being Campylobacter jejuni the most common species. Resistance to ciprofloxacin (65 %) and tetracycline (32 %) was found among 35 isolates of human origin studied. Seven genetic subtypes were observed among 13 C. jejuni isolates by pulsed field gel electrophoresis. Two subtypes grouped isolates belonging to patients and their respective dogs whereas another subtype grouped one isolate of human origin and two isolates from the patient's chickens. The results of this investigation highlight the need to strengthen surveillance of Campylobacter spp. not only in poultry, which is recognized as the main reservoir, but also in pets, which were shown to be asymptomatic carriers of the pathogen.

    Andrade, J A; Moreira, C; Fagundes Neto, U

    2000-07-01

    INTRODUCTION: Persistent diarrhea has high impact on infantile morbidity and mortality rates in developing countries. Several studies have shown that 3 to 20% of acute diarrheal episodes in children under 5 years of age become persistent. DEFINITION: Persistent diarrhea is defined as an episode that lasts more than 14 days. ETIOLOGY: The most important agents isolated in persistent diarrhea are: Enteropathogenic E. coli (EPEC), Salmonella, Enteroaggregative E. coli (EAEC), Klebisiella and Cryptosporidium. CLINICAL ASPECTS: In general, the clinical characteristics of patients with persistent diarrhea do not change with the pathogenic agent. Persistent diarrhea seems to represent the final result of a several insults a infant suffers that predisposes to a more severe episode of diarrhea due to a combination of host factors and high rates of enviromental contamination. Therefore, efforts should be made to promptly treat all episodes of diarrhea with apropriate follow-up. THERAPY: The aim of the treatment is to restore hydroelectrolytic deficits and to replace losses until the diarrheal ceases. It is possible in the majority of the cases, using oral rehydration therapy and erly an appropriate type of diet. PREVENTION: It is imperative that management strategies also focus on preventive aspects. The most effective diarrheal prevention strategy in young infants worldwide is promotion of exclusive breast feeding. PMID:14676915

  7. Prevalence study and genetic typing of bovine viral diarrhea virus (BVDV in four bovine species in China.

    Mingliang Deng

    Full Text Available To determine the nationwide status of persistent BVDV infection in different bovine species in China and compare different test methods, a total of 1379 serum samples from clinical healthy dairy cattle, beef cattle, yaks (Bos grunniens, and water buffalo (Bubalus bubalis were collected in eight provinces of China from 2010 to 2013. The samples were analyzed using commercial antibody (Ab and antigen (Ag detection kits, and RT-PCR based on the 5'-UTR and Npro gene sequencing. Results showed that the overall positive rates for BVDV Ab, Ag and RT-PCR detection were 58.09% (801/1379, 1.39% (14/1010, and 22.64% (146/645, respectively, while the individual positive rates varied among regions, species, and farms. The average Ab-positive rates for dairy cattle, beef cattle, yaks, and water buffalo were 89.49% (298/333, 63.27% (248/392, 45.38% (236/520, and 14.18% (19/134, respectively, while the Ag-positive rates were 0.00% (0/116, 0.77% (3/392, 0.82% (3/368, and 5.97% (8/134, respectively, and the nucleic acid-positive rates detected by RT-PCR were 32.06% (42/131, 13.00% (26/200, 28.89% (52/180, and 19.40% (26/134, respectively. In addition, the RT-PCR products were sequenced and 124 5'-UTR sequences were obtained. Phylogenetic analysis of the 5'-UTR sequences indicated that all of the 124 BVDV-positive samples were BVDV-1 and subtyped into either BVDV-1b (33.06%, BVDV-1m (49.19%, or a new cluster, designated as BVDV-1u (17.74%. Phylogenetic analysis based on Npro sequences confirmed this novel subtype. In conclusion, this study revealed the prevalence of BVDV-1 in bovine species in China and the dominant subtypes. The high proportion of bovines with detectable viral nucleic acids in the sera, even in the presence of high Ab levels, revealed a serious threat to bovine health.

  10. Addressing epidemiological and public health analytic challenges in outcome and impact research: a commentary on 'Prechewing Infant Food, Consumption of Sweets and Dairy and Not Breastfeeding are Associated with Increased Diarrhea Risk of Ten Month Old Infants'.

    Habicht, Jean-Pierre; Pelto, Gretel H

    2016-07-01

    Based on a paper by Conkle et al 2016, in which the authors use a descriptive epidemiological design to examine the relationship of premastication and other dietary behavioral variables to childhood diarrhea in the US, we address larger issues of "plausible causality" and the challenges involved in moving from epidemiological studies to public health policy. Drawing on examples from breastfeeding research and water, sanitation and hygiene (WASH) research, we discuss the following propositions: 1. Effective outcome analyses require simultaneous investigation of different, even contradictory, pathways; 2. Outcome versus impact assessments require different analytic procedures including context analysis; 3. Impact analysis requires understanding the trade-offs between detrimental and beneficial outcomes in relation to potential interventions; 4. No estimates exist for the likely detrimental and beneficial impacts of banning premastication, much less for their trade-offs. PMID:27229538

  11. Bovine viral diarrhea virus in free-ranging wild ruminants in Switzerland: low prevalence of infection despite regular interactions with domestic livestock

    Casaubon Julien

    2012-10-01

    Full Text Available Abstract Background In the frame of an eradication program for bovine viral diarrhea (BVD in Swiss livestock, the question was raised whether free-ranging wildlife could threaten the success of this sanitary measure. Therefore, we conducted serological and virological investigations on BVD virus (BVDV infections in the four indigenous wild ruminant species (roe deer, red deer, Alpine chamois and Alpine ibex from 2009 to 2011, and gathered information on interactions between wild and domestic ruminants in an alpine environment by questionnaire survey. Results Thirty-two sera out of 1’877 (1.7%, 95% confidence interval [CI] 1.2-2.4 were seropositive for BVDV, and a BVDV1 sub genotype h virus was found in a seropositive chamois (0.05%, 95% CI 0.001-0.3. The seropositive animals originated from sub-alpine or alpine regions and significantly more seropositive red deer, chamois and ibex than roe deer were found. There were no statistically significant differences between sampling units, age classes, genders, and sampling years. The obtained prevalences were significantly lower than those documented in livestock, and most positive wild ruminants were found in proximity of domestic outbreaks. Additionally, BVDV seroprevalence in ibex was significantly lower than previously reported from Switzerland. The survey on interspecific interactions revealed that interactions expected to allow BVDV transmission, from physical contacts to non-simultaneous use of the same areas, regularly occur on pastures among all investigated ruminant species. Interactions involving cervids were more often observed with cattle than with small ruminants, chamois were observed with all three domestic species, and ibex interacted mostly with small ruminants. Interactions related to the use of anthropogenic food sources were frequently observed, especially between red deer and cattle in wintertime. Conclusions To our knowledge, this is the first report of BVDV RNA isolated from an

    2016-03-01

    Traveler's diarrhea (TD) is the most common travel-related illness, and it can have a significant impact on the traveler. Pretravel consultation provides an excellent opportunity for the clinician to counsel the traveler and discuss strategies such as food and water hygiene, vaccinations, and medications for prophylaxis or self-treatment that may decrease the incidence and impact of TD. Postinfectious sequelae, such as postinfectious irritable bowel syndrome, reactive arthritis, and Guillain-Barre syndrome, may develop weeks or months after return. PMID:26900116

    Diarrhea is one of the most common diseases for which patients seek medical help. Most (more than 90%) cases of acute diarrhea are caused by enteropathogenic bacteria, viruses or parasites. Dehydration is the most frequent and most dangerous complication of diarrhea, but it can be managed with relatively simple procedures. Diarrhea in children is stiH a common reason for consulting a doctor and for hospital admission. Intravenous fluids are recommended for children with shock and/or severe de...

    Full Text Available CONTEXT: Acute diarrhea is a common cause of hospitalization among children under 5 years of age. Knowing the prevalence and risk factors associated with the severity of acute diarrhea is essential to control morbidity and mortality. OBJECTIVE: Describe the prevalence of demographic, epidemiologic and clinical features of children under 6 years of age hospitalized for acute diarrhea, and investigate the association between these determinants and the severity of the diarrheic episode. METHOD: Retrospective, cross-sectional study, during the period from January, 2005 through December, 2008, in the municipality of Juiz de Fora, MG, Brazil. Files from 6,201 children from 0 to 6 years of age, hospitalized in two public teaching institutions (which account for 84% of all the hospitalizations in the municipality, were assessed. Acute diarrhea was defined as the presence of at least three evacuations of liquid or loose stools, within 24 hours, for a maximum period of 14 days. The patients with acute diarrhea were divided in two groups, according to disease severity, severe diarrhea being considered whenever hospitalization lasted for at least 4 days. Epidemiologic and clinical data were assessed and compared through the application of the chi-squared test and the binomial logistic regression model. RESULTS: The prevalence rate for admission due to acute diarrhea was 8.4%. The factors significantly associated with the severity of the diarrheic episode were: age under 6 months (P = 0.01, OR = 2.762; disease onset during fall (P = 0.033, OR = 1.742, presence of fever (P = 0.017, OR = 1.715 and antibiotic use during hospitalization (P = 0.000, OR = 3.872. CONCLUSIONS: Diarrhea is the third most common cause of hospitalization among children under 6 years of age in Juiz de Fora. Young age (under or equal to 6 months, fever, antibiotic use during hospitalization and disease onset during fall are risk factors associated with longer hospital stay

  1. Insect Consumption to Address Undernutrition, a National Survey on the Prevalence of Insect Consumption among Adults and Vendors in Laos.

    Hubert Barennes

    Full Text Available Insect consumption (entomophagy is a potentially high nutritious and healthy source of food with high fat, protein, vitamin, fiber and micronutrient content. At least 2 billion people globally eat insects (over 1900 edible species though this habit is regarded negatively by others. There is a limited amount of data on the perception and consumption of insects. We conducted a national cross-sectional survey in the Lao People's Democratic Republic (Laos to assess the prevalence and characteristics of insect consumption among adult lay people and insect vendors.We conducted a multi stage randomized national survey in 1303 households in 96 villages in 16 Lao provinces. Three insect vendors or collectors per village were also included. A standardized pretested questionnaire addressed the following issues: socioeconomic characteristics, type of insects consumed and frequency of consumption, reasons and trends in consumption as well as reports on side effects, over the last 10 years.A total of 1059 adults (Sex ratio F/M: 1.2, 30 ethnic groups, and 256 vendors were enrolled. A total of 1025 (96.8% lay people were currently insect consumers, 135 (13.0% daily or weekly consumers, and 322 (31.1% consumed several times per month. For the majority (575, 55.6% the consumption was infrequent (less than a few times per year and only 22 (2% had never eaten insects. Consumption started in childhood. Insect availability was seasonal (670, 63.2% and respondents would have eaten more insects, if they had been more available (919, 86.7%. Hmong and Leu ethnic groups had significantly lower consumption levels than the general population. Eggs of weaver ants, short-tailed crickets, crickets, grasshoppers, and cicadas were the top 5 insects consumed. Consumption had decreased in the last decade, mostly due to less availability (869; 84.0% and change of life (29; 5.5%.

    Mireille Ângela Bernardes Sousa

    2013-02-01

    Full Text Available Introduction: Acute infectious diarrhea is still regarded as a public health problem associated with a wide range of etiologic agents, from which Salmonella enterica is particularly worth mentioning inasmuch as it is a major cause of inflammatory diarrhea in both developed and developing countries. Objective: To assess the distribution of S. enterica among children with acute diarrhea in Belo Horizonte and to characterize bacterium isolates. Material and methods: The study group comprised a total of 157 children from low socioeconomic background. Stool samples were collected for leukocyte analysis and Salmonella bacterial culture. The isolates were serotyped and evaluated as to antimicrobial susceptibility profile, extended-spectrum β-lactamases (ESBL production, and presence of virulence markers (invA, iroB, and spvC. RESULTS: A total of 5/3.2% children were infected by S. enterica, 3/60% by S. enterica Typhimurium, 1/20% by S. enterica Enteritidis and 1/20% S. enterica subsp. enterica serotype 8.20:z4,z23:-. Fecal leucocytes were detected in two out of five fecal specimens positive for S. enterica. Isolates from three children were resistant to nalidixic acid, nalidixic acid + chloramphenicol, and nalidixic acid + chloramphenicol + ampicillin. ESBL production was not detected. All samples presented invA and iroB genes. spvC marker was observed in isolates from two children infected by S. Typhimurium and S. Enteritidis. Conclusion: The results demonstrate that S. enterica infection is uncommon among children from our region. Furthermore, they indicate the need for periodic monitoring of bacterial antimicrobial susceptibility profile in order to establish suitable antimicrobial therapy when required.INTRODUÇÃO: A diarreia infecciosa aguda é considerada um problema de saúde pública associado a uma ampla gama de agentes etiológicos, entre os quais destaca-se Salmonella enterica, causa importante de diarreia inflamatória em pa

    2011-04-01

    Full Text Available Abstract Background Lack of exclusive breastfeeding among infants 0-5 months of age and no breastfeeding among children 6-23 months of age are associated with increased diarrhea morbidity and mortality in developing countries. We estimate the protective effects conferred by varying levels of breastfeeding exposure against diarrhea incidence, diarrhea prevalence, diarrhea mortality, all-cause mortality, and hospitalization for diarrhea illness. Methods We systematically reviewed all literature published from 1980 to 2009 assessing levels of suboptimal breastfeeding as a risk factor for selected diarrhea morbidity and mortality outcomes. We conducted random effects meta-analyses to generate pooled relative risks by outcome and age category. Results We found a large body of evidence for the protective effects of breastfeeding against diarrhea incidence, prevalence, hospitalizations, diarrhea mortality, and all-cause mortality. The results of random effects meta-analyses of eighteen included studies indicated varying degrees of protection across levels of breastfeeding exposure with the greatest protection conferred by exclusive breastfeeding among infants 0-5 months of age and by any breastfeeding among infants and young children 6-23 months of age. Specifically, not breastfeeding resulted in an excess risk of diarrhea mortality in comparison to exclusive breastfeeding among infants 0-5 months of age (RR: 10.52 and to any breastfeeding among children aged 6-23 months (RR: 2.18. Conclusions Our findings support the current WHO recommendation for exclusive breastfeeding during the first 6 months of life as a key child survival intervention. Our findings also highlight the importance of breastfeeding to protect against diarrhea-specific morbidity and mortality throughout the first 2 years of life.

    To examine the association between diarrhea in early childhood and malaria parasitemia, we conducted a nested case-control study in Guinea-Bissau of 297 children with diarrhea and a similar number of children without diarrhea matched for age, season, and residential area. There were no associations...... between diarrhea and parasite rate, parasite density, or clinical malaria. However, anti-malarials were easily available and frequently used, which was reflected by a 0.7% prevalence of children with a parasite density > 100/200 leukocytes. Thus, the findings do not preclude that diarrhea may be a sign of...

  9. Advances in understanding of bile acid diarrhea.

    Camilleri, Michael

    2014-01-01

    Bile acids (BA) are actively reabsorbed in the terminal ileum by the apical Na(+)-dependent bile salt transporter. This review addresses the epidemiology, pathophysiology, diagnosis and treatment of BA diarrhea (BAD). BAD is typically caused by ileal resection or disease; 25-33% of patients with chronic functional diarrhea or irritable bowel syndrome-diarrhea (IBS-D) have BAD, possibly from deficiency in the ileal hormone, FGF-19, which normally provides feedback inhibition of BA synthesis. Diagnosis of BAD is typically based on reduced BA retention of radiolabeled BA ((75)SeHCAT), increased BA synthesis (serum C4) or increased fecal BA loss. In clinical practice, diagnosis is often based on response to BA sequestrants (e.g., cholestyramine or colesevelam). Diagnostic tests for BA malabsorption (BAM) need to be used more extensively in clinical practice. In the future, farnesoid X receptor agonists that stimulate ileal production of FGF-19 may be alternative treatments of BAD. PMID:24410472

  10. Drug Therapy in Diarrhea

    1985-09-01

    Full Text Available The drug used in diarrhea must be effective in that they reduce the secretion and increase the absorption of the intestinal mucosa. This seems to be only possible with morphine derivatives. But these are not recommended as they may cause ileus. Antibiotics are indicated in only few cases of severe intestinal infections. Other frequently used drugs such as adsorbents are practically of no effect. Thus, rehydration, electrolyte substitution and realimentation remain the most effective method of treatment of acute diarrhea in infants.

    Parasitic diarrhea among children is a significant health problem worldwide. This cross sectional study described the burden of parasitic diarrhea among children. The objectives of this study were to evaluate the impact of risk factors on the parasitic diarrhea, and to determine the parasitic profile among children in Baghdad-Iraq, during the period extending from September 2003 to June 2004. A total number of 2033 cases were included in the study. The estimated prevalence rate of parasitic diarrhea was 22%. We identified the following major diarrhea determinants were large households size, residential location, water source, low socioeconomic status, and low parent education. Giardia lamblia was found to be the most prevalent parasite with an infection rate of 45.54% followed by Entamoeba histolytica 23.44%, Enterobius vermicularis 12.7%, Hymenolepis nana 9.82%, Trichuris trichiura 5.4%, and Ascaris lumbricoides 2.2%. In conclusion, this study demonstrates that poor sanitation, inadequate environmental conditions, and low socioeconomic status are the main determining factors that predispose children to parasitic diarrhea. Mass deworming programs are recommended for school children, as this population is easily accessible. PMID:25382477

    2016-01-01

    Full Text Available Background and Objectives: Incidence of hospital-acquired diarrhea has increased rapidly and burn patients are at high risk of getting it. Infection with C. difficile is the most common cause of antibiotic associated diarrhea. The aim of this study was to determine the baseline characteristics and clinical presentation of hospital-acquired diarrhea and compare C. difficile and non-C. difficile diarrhea in burn patients treated at a burn center.Materials and Methods: During a 1-year study all patients with hospital-acquired diarrhea at Motahari Burn Hospital, Teh- ran, Iran enrolled in this study. We compared patients with a stool sample positive for C. difficile toxin or tracing the antigen in patients who were negative for detection of toxin in their stool sample specimens.Results: Diarrhea developed in 37 patients out of 3200 admitted patients with a mean burn size of 34.8 ±20.1%. Among them, 8 patients had a positive result for C. difficile. The mean time between antibiotic therapy and occurrence of diarrhea was 9.5 ± 6.2 days. Nine (23.7% patients died in the 7.8± 4.2 days, mostly due to co-morbidities. The mean duration of di- arrhea was 3.6 ± 2 days. Twenty two (57.9% patients were treated with oral metronidazol and eleven (28.9% patients were treated with combination of metronidazole and vancomycin, higher rate of combination therapy was seen in Clostridium difficile CDI.Conclusion: Overall, the prevalence of hospital-acquired diarrhea was 120/10,000  and 21% of them caused by infection with C. difficile. Presence of peripheral leukocytosis and colitis were the alarm sign for diagnosis of C. difficile infection. Keywords: Hospital-acquired diarrhea (HAD, Burn, Clostridium difficile infection (CDI

  17. Post-irradiation diarrhea

    In radiotherapy of pelvic cancers, the X-ray dose to be delivered to the tumour is limited by the tolerance of healthy surrounding tissue. In recent years, a number of serious complications of irradiation of pelvic organs were encountered. Modern radiotherapy necessitates the acceptance of a calculated risk of complications in order to achieve a better cure rate. To calculate these risks, one has to know the radiation dose-effect relationship of normal tissues. Of the normal tissues most at risk when treating pelvic tumours only the bowel is studied. In the literature regarding post-irradiation bowel complications, severe and mild complications are often mixed. In the present investigation the author concentrated on the group of patients with relatively mild symptoms. He studied the incidence and course of post-irradiation diarrhea in 196 patients treated for carcinoma of the uterine cervix or endometrium. The aims of the present study were: 1) to determine the incidence, course and prognostic significance of post-irradiation diarrhea; 2) to assess the influence of radiotherapy factors; 3) to study the relation of bile acid metabolism to post-irradiation diarrhea; 4) to investigate whether local factors (reservoir function) were primarily responsible.

  18. Pharmacologic Agents for Chronic Diarrhea.

    Lee, Kwang Jae

    2015-10-01

    Chronic diarrhea is usually associated with a number of non-infectious causes. When definitive treatment is unavailable, symptomatic drug therapy is indicated. Pharmacologic agents for chronic diarrhea include loperamide, 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists, diosmectite, cholestyramine, probiotics, antispasmodics, rifaximin, and anti-inflammatory agents. Loperamide, a synthetic opiate agonist, decreases peristaltic activity and inhibits secretion, resulting in the reduction of fluid and electrolyte loss and an increase in stool consistency. Cholestyramine is a bile acid sequestrant that is generally considered as the first-line treatment for bile acid diarrhea. 5-HT3 receptor antagonists have significant benefits in patients with irritable bowel syndrome (IBS) with diarrhea. Ramosetron improves stool consistency as well as global IBS symptoms. Probiotics may have a role in the prevention of antibiotic-associated diarrhea. However, data on the role of probiotics in the treatment of chronic diarrhea are lacking. Diosmectite, an absorbent, can be used for the treatment of chronic functional diarrhea, radiation-induced diarrhea, and chemotherapy-induced diarrhea. Antispasmodics including alverine citrate, mebeverine, otilonium bromide, and pinaverium bromide are used for relieving diarrheal symptoms and abdominal pain. Rifaximin can be effective for chronic diarrhea associated with IBS and small intestinal bacterial overgrowth. Budesonide is effective in both lymphocytic colitis and collagenous colitis. The efficacy of mesalazine in microscopic colitis is weak or remains uncertain. Considering their mechanisms of action, these agents should be prescribed properly. PMID:26576135

  19. Epidemiology of functional diarrhea and comparison with diarrhea-predominant irritable bowel syndrome: a population-based survey in China.

    Yan-Fang Zhao

    Full Text Available BACKGROUND: The epidemiology of functional diarrhea and its impacts on Chinese remain unclear, and there are no data on the comparative epidemiology of functional diarrhea and diarrhea-predominant irritable bowel syndrome (IBS-D. This study was to explore the epidemiology of functional diarrhea and its impacts, and to identify its distinction from IBS-D. METHODS AND FINDINGS: A cross-sectional survey was conducted in 16078 respondents, who were interviewed under a randomized stratified multi-stage sampling design in five cities of China. All respondents completed the modified Rome II questionnaire, and the 36-item Short Form health survey (SF-36 was used for assessing health-related quality of life in 20% of the sample. Overall, 248 respondents (1.54% had functional diarrhea and 277 (1.72% had IBS-D. Functional diarrhea was positively associated with increasing age and body mass index (trend test P<0.05. The three most common symptoms for at least 3 weeks in the past months were loose, mushy or watery stools (n = 203, 81.85%, more than three bowel movements a day (n = 100, 40.32% and having to rush to the toilet to have a bowel movement (n = 72, 29.03%. Meaningful impairment was observed in 5 of the 8 SF-36 domains in respondents with functional diarrhea. The demographics are mostly similar between the respondents with functional diarrhea and IBS-D; however, respondents with IBS-D had more frequent symptoms of diarrhea and even lower scores in SF-36 domains than those with functional diarrhea. CONCLUSIONS: The prevalence of functional diarrhea in China is substantially lower than that in Western countries and relatively higher than that in other Asian countries. It impaired health-related quality of life, and respondents with IBS-D have even worse quality of life. Further population-based studies are needed to investigate the epidemiology of functional diarrhea and the differences between functional diarrhea and IBS-D.

  4. Acute diarrhea in children

    Radlović Nedeljko

    2015-01-01

    Full Text Available Acute diarrhea (AD is the most frequent gastroenterological disorder, and the main cause of dehydration in childhood. It is manifested by a sudden occurrence of three or more watery or loose stools per day lasting for seven to 10 days, 14 days at most. It mainly occurs in children until five years of age and particularly in neonates in the second half-year and children until the age of three years. Its primary causes are gastrointestinal infections, viral and bacterial, and more rarely alimentary intoxications and other factors. As dehydration and negative nutritive balance are the main complications of AD, it is clear that the compensation of lost body fluids and adequate diet form the basis of the child’s treatment. Other therapeutic measures, except antipyretics in high febrility, antiparasitic drugs for intestinal lambliasis, anti-amebiasis and probiotics are rarely necessary. This primarily regards uncritical use of antibiotics and intestinal antiseptics in the therapy of bacterial diarrhea. The use of antiemetics, antidiarrhetics and spasmolytics is unnecessary and potentially risky, so that it is not recommended for children with AD.

    2016-09-25

    Rotaviruses (RVs) are a major cause of severe diarrhea in humans and animals. Five of the nine RV groups (RVA, RVB, RVC, RVE, and RVH) have been previously detected in pigs; however, in pig herds worldwide, most studies highlight diarrhea outbreaks caused by RVA. In the present study, we describe detection and characterization of RV groups A, B, C, and H in fecal samples from pigs with single and mixed infections during a post-weaning diarrhea outbreak. The outbreak occurred in a single pig herd routinely vaccinated with an inactivated commercial vaccine for neonatal diarrhea control that included the RVA OSU (G5P[7]) strain. RVC (78%) was the most prevalent group found in single (34%) and mixed (44%) infections, followed by RVA (46%), RVB (32%), and RVH (18%). Phylogenetic analysis of three RVA strains allowed the characterization of two distinct G/P genotypes represented by G5P[13] and G9P[23], different from G5P[7] found in vaccines. Regardless of the RV group, mixed infections (54%) were more prevalent than single infections. Detection of RVB or RVH was associated with the presence of other RV groups, suggesting a secondary action of these RV groups in the reported outbreak. The detection of RV groups B, C, and H in the same pig herd suggests that these RVs act as causative agents of diarrhea and should be included in the diagnostic tests of porcine enteric diseases. These data provide new epidemiological information on RV diversity that need to be addressed in future studies for a better understanding and prevention of RV infections. PMID:27599939

    Anita Chakravarti; Manisha Jain; Mayank Singh Chauhan; Anju Sharma; Sayani Tewari

    2010-01-01

    Objective:To screen for the presence of mixed infection with rotavirus. Methods:The present study included 140 children aged less than 2 years with acute diarrhea. Fecal samples of all these patients were analyzed for the presence of astroviral antigen by enzyme immunoassay. Also 40 rotavirus positive fecal samples were screened for the presence of astrovirus. Results:In case of acute diarrhea in children the prevalence of astrovirus was around 34%(48/140). It was seen that even in rotavirus positive cases astrovirus co infection was 25%. Conclusions:Astrovirus is a growing problem which is often underrecognised. With the rotavirus vaccine licensure being imminent astrovirus will emerge out as the single most important cause of viral diarrhea.

    To identify enteropathogens for vaccine development, we implemented clinic-based surveillance for severe pediatric diarrhea in Egypt's Nile River Delta. Over 2 years, a physician clinically evaluated and obtained stool samples for microbiology from patients with diarrhea and less than 6 years of age. In the first (N = 714) and second clinic (N = 561), respectively, 36% (N = 254) and 46% (N = 260) of children were infected with rotavirus, enterotoxigenic Escherichia coli (ETEC), Campylobacter, or Shigella. When excluding mixed rotavirus-bacterial infections, for the first and second clinic, 23% and 10% had rotavirus-associated diarrhea, and 14% and 17% had ETEC-associated diarrhea, respectively. Campylobacter-associated diarrhea was 1% and 3%, and Shigella-associated diarrhea was 2% and 1%, respectively, for the two clinics. Rotavirus-associated diarrhea peaked in late summer to early winter, while bacterial agents were prevalent during summer. Rotavirus-associated cases presented with dehydration, vomiting, and were often hospitalized. Children with Shigella- or Campylobacter-associated diarrhea reported as watery diarrhea and rarely dysentery. ETEC did not have any clinically distinct characteristics. For vaccine development and/or deployment, our study suggests that rotavirus is of principle concern, followed by ETEC, Shigella, and Campylobacter. PMID:16407360

    AIM: To explore the characteristics of diarrhea caused by acaroid mites.METHODS: Acaroid mites in fresh stools of 241 patients with diarrhea were separated by flotation in saturated saline.Meanwhile, skin prick test, total IgE and mite-specific IgE were detected in all patients.RESULTS: The total positive rate of mites in stool samples of the patients was 17.01% (41/241), the positive rates of mites in male and female patients were 15.86 % (23/145)and 18.75 % (18/96), respectively, without significant difference (P>0.05). The percentage of skin prick test as ″+++″″++ ″″+ ″″±″″-″ was″+++, ″++″,″ +″, ″±″ and ″-″was 9.13 % (22/241), 7.47 %(18/241), 5.81% (14/241), 4.98 % (12/241) and 72.61%(175/241), respectively. The serum levels of total IgE, mitespecific IgE in patients with and without mites in stool samples were (165.72±78.55) IU/ml, (132.44±26.80) IU/ml and (145.22±82.47) IU/ml, (67.35±45.28) IU/ml,respectively, with significant difference (P<0.01). The positive rate of mites in stool samples in staffs working in traditional Chinese medicine storehouses or rice storehouses (experimental group) was 26.74 % (23/86), which was significantly higher than that (11.61%, 18/155) in people engaged in other professions (X2=8.97, P<0.01).CONCLUSION: Acaroid mites cause diarrhea and increase serum levels of total IgE and mite-specific IgE of patients,and the prevalence of diarrhea caused by acaroid mites is associated with occupations rather than the gender of patients.

  14. Syndromic diarrhea/Tricho-hepato-enteric syndrome

    2013-01-01

    Abstract Syndromic diarrhea/Tricho-hepato-enteric syndrome (SD/THE) is a rare and severe bowel disorder caused by mutation in SKIV2L or in TTC37, 2 genes encoding subunits of the putative human SKI complex. The estimated prevalence is 1/1,000,000 births and the transmission is autosomal recessive. The classical form is characterized by 5 clinical signs: intractable diarrhea of infancy beginning in the first month of life, usually leading to failure to thrive and requiring parenteral nutrition; facial dysmorphism characterised by prominent forehead and cheeks, broad nasal root and hypertelorism; hair abnormalities described as woolly and easily removable; immune disorders resulting from defective antibody production; intrauterine growth restriction. The aetiology is a defect in TTC37, a TPR containing protein, or in the RNA helicase SKIV2L, both constituting the putative human ski complex. The ski complex is a heterotetrameric cofactor of the cytoplasmic RNA exosome which ensures aberrants mRNAs decay. The diagnosis SD/THE is initially based on clinical findings and confirmed by direct sequencing of TTC37 and SKIV2L. Differential diagnosis with the other causes of intractable diarrhea is easily performed by pathologic investigations. During their clinical course, most of the children require parenteral nutrition and often immunoglobulin supplementation. With time, some of them can be weaned off parenteral nutrition and immunoglobulin supplementation. The prognosis depends on the management and is largely related to the occurrence of parenteral nutrition complications or infections. Even with optimal management, most of the children seem to experience failure to thrive and final short stature. Mild mental retardation is observed in half of the cases.

    Full Text Available The objective of this study was to determine the prevalence and to identify risk factors associated with Giardia lamblia infection in diarrheic children hospitalized for diarrhea in Goiânia, State of Goiás, Brazil. A cross-sectional study was conducted and a comprehensive questionnaire was administered to the child's primary custodian. Fixed effects logistic regression was used to determine the association between infection status for G. lamblia and host, sociodemographic, environmental and zoonotic risk factors. A total of 445 fecal samples were collected and processed by the DFA methodology, and G. lamblia cysts were present in the feces of 44 diarrheic children (9.9%. A variety of factors were found to be associated with giardiasis in these population: age of children (OR, 1.18; 90% CI, 1.0 - 1.36; p = 0.052, number of children in the household (OR 1.45; 90% CI, 1.13 - 1.86; p = 0.015, number of cats in the household (OR, 1.26; 90% CI, 1.03 -1.53; p = 0.059, food hygiene (OR, 2.9; 90% CI, 1.34 - 6.43; p = 0.024, day-care centers attendance (OR, 2.3; 90% CI, 1.20 - 4.36; p = 0.034, living on a rural farm within the past six months prior hospitalization (OR, 5.4; CI 90%, 1.5 - 20.1; p = 0.03 and the number of household adults (OR, 0.59; 90% CI, 0.42 - 0.83; p = 0.012.

  16. Presidential address.

    Vohra, U

    1993-07-01

    The Secretary of India's Ministry of Health and Family Welfare serves as Chair of the Executive Council of the International Institute for Population Sciences in Bombay. She addressed its 35th convocation in 1993. Global population stands at 5.43 billion and increases by about 90 million people each year. 84 million of these new people are born in developing countries. India contributes 17 million new people annually. The annual population growth rate in India is about 2%. Its population size will probably surpass 1 billion by the 2000. High population growth rates are a leading obstacle to socioeconomic development in developing countries. Governments of many developing countries recognize this problem and have expanded their family planning programs to stabilize population growth. Asian countries that have done so and have completed the fertility transition include China, Japan, Singapore, South Korea, and Thailand. Burma, Malaysia, North Korea, Sri Lanka, and Vietnam have not yet completed the transition. Afghanistan, Bangladesh, Iran, Nepal, and Pakistan are half-way through the transition. High population growth rates put pressure on land by fragmenting finite land resources, increasing the number of landless laborers and unemployment, and by causing considerable rural-urban migration. All these factors bring about social stress and burden civic services. India has reduced its total fertility rate from 5.2 to 3.9 between 1971 and 1991. Some Indian states have already achieved replacement fertility. Considerable disparity in socioeconomic development exists among states and districts. For example, the states of Bihar, Madhya Pradesh, Rajasthan, and Uttar Pradesh have female literacy rates lower than 27%, while that for Kerala is 87%. Overall, infant mortality has fallen from 110 to 80 between 1981 and 1990. In Uttar Pradesh, it has fallen from 150 to 98, while it is at 17 in Kerala. India needs innovative approaches to increase contraceptive prevalence rates

  17. Calcium ameliorates diarrhea in immune compromised children

    Cheng, Sam X.; Bai, Harrison X; Gonzalez-Peralta, Regino; Mistry, Pramod K.; Gorelick, Fred S.

    2013-01-01

    Treatment of infectious diarrheas remains a challenge, particularly in immunocompromised patients in whom infections usually persist and resultant diarrhea is often severe and protracted. Children with infectious diarrhea who become dehydrated are normally treated with oral or intravenous rehydration therapy. Although rehydration therapy can replace the loss of fluid, it does not ameliorate diarrhea. Thus, over the past decades, there has been continuous effort to search for ways to safely st...

  1. Oral rehydration salts, zinc supplement and rota virus vaccine in the management of childhood acute diarrhea

    Abdulwahab MA Telmesani

    2010-01-01

    Full Text Available Acute diarrhea remains a major cause of morbidity and mortality in children. Since the introduction of oral rehydration salts (ORS mortality has dropped to less than 50% worldwide. Low osmolarity ORS improved the outcome and reduced the hospitalization further. Zinc difficiency has been found to be associated with severe episodes of acute diarrhea. Zinc supplement in developing countries did reduce the incidence and prevalence of diarrhea. In addition, Zinc supplement significantly reduced the severity of diarrhea and duration of the episode. In the Americas and Europe, Rota virus vaccine was 90% effective in preventing severe episodes of severe rotavirus gastroenteritis. This review concludes that low osmolarilty ORS, zinc supplementation and rotavirus vaccine are major factors in reducing the morbidity, mortality and hospitalization resulting from to acute gastroenteritis in childhood.

    2015-01-01

    Enteric viruses have been shown to be responsible for diarrhea among children during their early childhood. This study was carried out to determine the prevalence of rotavirus, adenovirus, and norovirus infection in young children with diarrhea in two primary health centers in Edo State, Nigeria. A total of 223 stool specimens were collected from children aged 0–36 months with clinical signs of diarrhea and 59 apparently healthy age-matched children as control. These specimens were investigated for three viral agents using immunochromatographic technique (ICT). The overall results showed that at least one viral agent was detected in 95/223 (42.6%) of the children with diarrhea while the control had none. The prevalence of rotavirus was 28.3%, adenovirus 19.3%, and norovirus 3.6%. There was a significant association between age group and infection (P < 0.0001). Seasonal pattern of enteric viruses was not statistically significant (P = 0.17). The overall coinfection rate was 7.6% and rotavirus-adenovirus coinfection had the highest with 5.4%. Rotavirus was the most prevalent viral agent. Coinfections are not uncommon among the population studied. The most commonly associated clinical symptom of viral diarrhea in this study was vomiting. Viral diagnostic tests are advocated for primary health care facilities in this locality. PMID:26064123

    Vohmann, B; Hoffmann, J C

    2013-11-01

    Chronic diarrhea can be caused by multiple disease entities. Basic diagnostic tests are required in order to administer specific therapies whenever possible. If no specific treatment can be used, a symptomatic management should be initiated in order to prevent massive electrolyte- and water losses. Substances that can be used are loperamide, cholestyramine, bulking agents, probiotics, anticholinergic agents and in severe cases opioids. If used properly these agents can be prescribed longterm with an acceptable side effect profile. PMID:24163167

    2014-12-01

    This study examined the relationship between childhood diarrhea prevalence and caregiver knowledge of the causes and prevention of diarrhea in a prospective cohort of 952 children Cochabamba, Bolivia. The survey of caregiver knowledge found that more than 80% of caregivers were unaware that hand washing with soap could prevent childhood diarrhea. Furthermore, when asked how to keep food safe for children to eat only 17% of caregivers reported hand washing before cooking and feeding a child. Lack of caregiver awareness of the importance of practices related to hygiene and sanitation for diarrhea prevention were significant risk factors for diarrheal disease in this cohort. The knowledge findings from this study suggest that health promotion in these communities should put further emphasis on increasing knowledge of how water treatment, hand washing with soap, proper disposal of child feces, and food preparation relate to childhood diarrhea prevention.

  6. Observational Study of Travelers' Diarrhea.

    Meuris

    1995-03-01

    Background: European air travelers returning from Algeria, Egypt, Mexico, Morocco, and Tunisia were interviewed about their experience of travelers' diseases upon arrival in Brussels. Diarrhea was mentioned by 37% of the adults and 27% of the children. These subjects were questioned about the types of measures taken, type and duration of drug treatment (if any), and about duration of diarrhea and side effects experienced. Methods: Final analysis was performed based on 2160 interviews. The largest proportion of diarrhea was reported in the age group 15-24 years (46%). Results: The majority of the 2160 subjects had opted for drug treatment (81%): 927 subjects for loperamide alone, 235 for loperamide in combination with nifuroxazide, and 178 for nifuroxazide alone. Other drugs had been used less frequently. The median time to recovery was 2.4 days with loperamide compared to 3.2 days with nifuroxazide and to 3.4 days for the no-treatment group. Conclusions: A stratification of the results by severity of the diarrhea suggests a rank of antidiarrheal potency as follows: loperamide > nifuroxazide > no-drug treatment. The side effect with the highest incidence was constipation (2.4% with loperamide). (J Travel Med 2:11-15, 1995) Travelers' diarrhea is usually defined as the passage of at least three unformed stools per day or any number of such stools when accompanied by fever, abdominal cramping, or vomiting. The definition may be broadened to include more trivial bowel disturbance.1,2 The duration of this self-limited disease generally is 3 to 5 days. Medical intervention aims at shortening the duration of disease, thus allowing the sufferer to resume his or her usual activities at an early stage. A shortened period of recovery to physical well-being has obvious favorable economic implications if the traveler is on business and may help the maintenance of a desired level of quality of life while a traveler is on holiday.

    Bovine viral diarrhea virus (BVDV) is classified into two species, namely, Bovine viral diarrhea virus 1 and Bovine viral diarrhea virus 2, and affects cattle worldwide, resulting in significant economic loss. The prevalence of BVDV-1 and BVDV-2 infections and its genotypes in Mongolian animals has not been studied. In this study, we surveyed BVDV infection in dairy cattle and yaks from Bornuur and Bulgan counties by RT-PCR, and the average infection rate in the sampling sites was 15.8 % and 20.0 %, respectively. In addition, molecular features of the 5'-UTR region of the BVDV genome in Mongolian cattle and yaks were identified as belonging to the subtypes BVDV-1a and BVDV-2a, respectively. Determining the prevalence, geographical distribution, and molecular diversity of BVDV-1 and BVDV-2 in various host species in Mongolia is important for further studies and process control programs.

  12. Effective prophylaxis against rotavirus diarrhea using a combination of Lactobacillus rhamnosus GG and antibodies

    Hammarström Lennart

    2007-09-01

    Full Text Available Abstract Background Rotavirus is a worldwide cause of infectious infantile diarrhea that claims over 600,000 lives annually. Recently, two new vaccine candidates have been developed but their efficacy in developing countries, still remains to be proven. Oral delivery of specific immunoglobulins provides passive immunity and is a fast acting treatment for rotavirus diarrhea. Probiotic bacteria have also gained considerable attention lately as treatment for rotavirus diarrhea. Here we report an evaluation of the therapeutic potential of different probiotics and their combination with anti – rotavirus antibodies in a mouse model of rotavirus diarrhea. Results Of the six probiotic bacteria tested, Lactobacillus rhamnosus strain GG had the strongest influence in reducing prevalence, duration and severity of diarrhea and was therefore chosen for combination treatment with immunoglobulins. The combination treatment reduced the diarrhea outcome measures significantly, prevented histopathological changes and reduced the virus load in the intestines. Conclusion The advantages associated with immunoglobulins and probiotics based therapy is that the treatment provides a rapid therapeutic effect and is cost efficient. These components do not require special storage conditions and could potentially complement the rehydration therapy that is currently used.

    2013-11-01

    Full Text Available Background The incidence of diarrhea in Indonesia has declined in the past five years. In spite of the increasing number of studies on the treatment for acute diarrhea, especially the use of zinc, it is not known if bacterial vs. non-bacterial etiology makes a difference in the reduction of severity of acute diarrhea in children on zinc therapy. Objective To assess the effect of zinc therapy in reducing the severity of acute bacterial and non-bacterial diarrhea. Methods We performed a cross-sectional study in the Secanggang District, Langkat Regency of North Sumatera, from August to November 2009 in children aged 2 months to 14 years. Microscopic stool examinations were undertaken to separate subjects into the acute bacterial or non-bacterial diarrhea groups. Both groups received 10 mg/day of zinc sulphate for subjects aged <6 months or 20 mg/day for those aged ≥6 months for 10 days. Measurement of disease severity was based on the frequency of diarrhea (times/day and the duration of diarrhea (hours after initial drug consumption. We performed independent T-test for statistical analysis. Results Sixty-two children participated in this study, with 31 children in the acute bacterial group, and the remainder in the non-bacterial group. There were no significant differences between the two groups in frequency of diarrhea (2.61 vs 2.70 times/day, respectively, P=0.27 or in duration of diarrhea (63.39 vs 66.68 hours, respectively, P=0.06. Conclusion Zinc is not more effective in reducing the severity of acute bacterial diarrhea compared to non-bacterial diarrhea in children. [Paediatr Indones. 2013;53:334-8.].

    As mast cells have been highlighted in the pathogenesis of diarrhea-predominant irritable bowel syndrome, a new term "mastocytic enterocolitis" was suggested by Jakate and colleagues to describe an increase in mucosal mast cells in patients with chronic intractable diarrhea and favorable response to treatment with antihistamines. Although it is not an established disease entity, two cases have been reported in the English medical literature. Here, for the first time in Asia, we report another case of chronic intractable diarrhea caused by gastrointestinal mastocytosis. The patient was a 70-year-old male with chronic intractable diarrhea for 3 months; the cause of the diarrhea remained obscure even after exhaustive evaluation. However, biopsy specimens from the jejunum were found to have increased mast cell infiltration, and the patient was successfully treated with antihistamines. PMID:27433151

    2012-05-01

    Full Text Available With the purpose of an estimation of the contribution of virus activators in the etiological structure of acute intestinal infections in children during the rise of prevalence of acute intestinal infections from 2009 to 2011 there were studied 1050 children admitted to the hospital with diarrheal diseases. It is established, that acute intestinal infections have a viral nature in 56.67% of cases. Thus the leading role belongs to rotaviruses and adenoviruses. Infectious agents of diarrheal diseases are rotaviruses in 28.1 % of cases, adenoviruses - in 17.05 %, and astroviruses - in 11.43 %. The viral monoinfections occur more often, than mixed-infections. The rise of sporadic diseases of viral diarrhea was characterized by seasonal prevalence. For intestinal infections of viral etiology the seasonal rise in a cold season with peak of the rate of diseases of rotaviral infection in April, adenoviral infection in November, and astroviral infection in December is characteristic.

    This paper addresses various aspects of the bases underlying the nuclear third party liability regime, and also analyses the distinction between danger and risk and the manner in which damage caused by flood, mass unemployment (economic damage mainly) and certain diseases is dealt with in the absence of liability provisions similar to those applicable to nuclear incidents. It also is suggested that the State because of its duty under the Basic Law to ensure adequate energy supplies, should be co-responsible for liability questions along with the nuclear operator.

    In this case report we present in detail the complex nature of enteral feeding, diarrhea, hypoalbuminemia, and edema in a critically ill patient. We also discuss the use of a peptide-elemental formula in this patient, who suffered continuous diarrhea for 15 weeks after liver transplantation. Use of this formula was associated with cessation of the diarrhea and permitted adequate nutritional delivery. After 26 weeks of mechanical pulmonary ventilation, extubation was possible. This case illustrates the ineffectiveness of parenteral albumin infusions for treatment of enteral edema and demonstrates the restoration of normal intestinal absorptive capacity when ultrafiltration was instituted and the patient's generalized edematous state was corrected.

    2011-05-01

    Full Text Available Abstract Background Diarrhea remains the second leading cause of death in children under 5 years of age in sub-Saharan Africa. Health care seeking behavior for diarrhea varies by context and has important implications for developing appropriate care strategies and estimating burden of disease. The objective of this study was to determine the proportion of children under five with diarrhea who consulted at a health structure in order to identify the appropriate health care levels to set up surveillance of severe diarrheal diseases. Methods A cluster survey was done on 35 clusters of 21 children under 5 years of age in each of four districts of the Maradi Region, Niger. Caretakers were asked about diarrhea of the child during the recall period and their health seeking behavior in case of diarrhea. A weighted cluster analysis was conducted to determine the prevalence of diarrhea, as well as the proportion of consultations and types of health structures consulted. Results In total, the period prevalence of diarrhea and severe diarrhea between April 24th and May 21st 2009 were 36.8% (95% CI: 33.7 - 40.0 and 3.4% (95% CI: 2.2-4.6, respectively. Of those reporting an episode of diarrhea during the recall period, 70.4% (95% CI: 66.6-74.1 reported seeking care at a health structure. The main health structures visited were health centers, followed by health posts both for simple or severe diarrhea. Less than 10% of the children were brought to the hospital. The proportion of consultations was not associated with the level of education of the caretaker, but increased with the number of children in the household. Conclusions The proportion of consultations for diarrhea cases in children under 5 years old was higher than those reported in previous surveys in Niger and elsewhere. Free health care for under 5 years old might have participated in this improvement. In this type of decentralized health systems, the WHO recommended hospital-based surveillance of

  7. The Influence of Episode Severity on Caregiver Recall, Care-seeking, and Treatment of Diarrhea Among Children 2-59 Months of Age in Bihar, Gujarat, and Uttar Pradesh, India.

    Increased diarrheal episode severity has been linked to better 2-week recall and improved care-seeking and treatment among caregivers of children under five. Using cross-sectional data from three Indian states, we sought to assess the relationship between episode severity and the recall, care-seeking, and treatment of childhood diarrhea. Recall error was higher for episodes with onset 8-14 days (31.2%) versus 1-7 days (4.8%) before the survey, and logistic regression analysis showed a trend toward increased severity of less recent compared with more recent episodes. This finding indicates that data collection with 2-week recall underestimates diarrhea prevalence while overestimating the proportion of severe episodes. There was a strong correlation between care-seeking and dehydration, fever, vomiting, and increased stool frequency and duration. Treatment with oral rehydration salts was associated with dehydration, vomiting, and higher stool frequency, and trends were established between therapeutic zinc supplementation and increased duration and stool frequency. However, state and care-seeking sector were stronger determinants of treatment than episode severity, illustrating the need to address disparities in treatment quality across regions and delivery channels. Our findings are of importance to researchers and diarrhea management program evaluators aiming to produce accurate estimates of diarrheal outcomes and program impact in low- and middle-income countries.

    2011-01-01

    Background There has been a marked global increase in the incidence of human Campylobacter enteritis in recent years. This study investigated the epidemiological and clinical features of Campylobacter enteritis in adult patients suffering from acute diarrhea.Methods This was a retrospective review of Campylobacter enteritis in adult patients with acute diarrhea presenting at Beijing University First Hospital, Beijing, China, in the summer and autumn (April to October) of 2005 to 2009. The data collected included the species of campylobacter identified, and the age, gender, clinical manifestations and results of laboratory test on stool samples collected from the patients. Campylobacter sensitivity tests to various antimicrobial agents were conducted on 80 specimens. Chi-square tests were applied using SPSS13.0 software and a two-sided P value of <0.05 was considered statistically significant.Results Campylobacter spp. isolated from the stool specimens of 142 patients with diarrhea represented 14.9% of all the cases examined. C. jejuni was identified in 127 patients (89.4%) and C. coli in 15 others (10.6%). The infection incidence was highest in the age range of 21-30 years which comprised 21.7% of the total cases examined. Most cases of diarrhea (46 patients) occurred in June. Watery diarrhea (97.2%), abdominal pain (72.5%) and fever (64.8%) were the most common manifestations of enteric campylobacteriosis. Only four patients (2.8%) had bloody diarrhea. The antimicrobial resistance rates were: cefoperazone (100%), levofloxacin (61.3%), gentamicin (12.5%), erythromycin (6.3%), and azithromycin (2.5%).Conclusions Campylobacter was prevalent among adults with acute diarrhea from 2005 to 2009 in Beijing, China. The large number of those afflicted by the disease warrants the commission of a large multicenter study to determine the extent of enteric campylobacteriosis in this region.

    The impact of the Chernobyl accident on health has been dramatic but different than expected. It has posed a tremendous health, social and economic burden on the people of Belarus, the Russian Federation and Ukraine. Now the picture of the impact of the accident on health and environment is clearer and the agenda can further move towards development and focused health programmes. The work of the Chernobyl Forum, which allowed this important objective to be reached, is an example of the multiplied added value that different United Nations agencies working together can achieve when addressing complex problems affecting large communities in an independent, comprehensive and credible way. This model should be the basis for future action with the Member States towards reconstruction, development and better health

  12. Probiotics and Antibiotic-Associated Diarrhea and Clostridium difficile Infection

    Surawicz, Christina M.

    Diarrhea is a common side effect of antibiotics. Antibiotics can cause diarrhea in 5-25% of individuals who take them but its occurrence is unpredictable. Diarrhea due to antibiotics is called antibiotic-associated diarrhea (AAD). Diarrhea may be mild and resolve when antibiotics are discontinued, or it may be more severe. The most severe form of AAD is caused by overgrowth of Clostridium difficile which can cause severe diarrhea, colitis, pseudomembranous colitis, or even fatal toxic megacolon. Rates of diarrhea vary with the specific antibiotic as well as with the individual susceptibility.

    Diarrhea represents one of the most frequent disorders in dogs. In puppies, degradation of feces quality is associated with a reduced daily weight gain and an increased risk of death. Prevention of diarrhea in puppies requires a global approach encompassing enteropathogens, environment and management practices especially when housed in groups. The purpose of this study was to determine prevalence of enteropathogens in puppies in breeding kennels and to identify risk factors of diarrhea. Two hundred and sixty six puppies (between 5 and 14 weeks of age) from 29 French breeding kennels were included. For each kennel, data about environment, management of the kennel and puppies' characteristics (age, sex and breed) were collected. For each puppy, fecal consistency and fecal excretion of enteropathogens (viruses and parasites) was evaluated. At least one enteropathogen was identified in 77.1% of puppies and 24.8% of puppies presented abnormal feces. The main risk factor of weaning diarrhea was fecal excretion of canine parvovirus type 2 (odds ratio=5; confidence interval 95%: 1.7-14.7). A targeted sanitary and medical prophylaxis against canine parvovirus type 2 should be implemented to decrease risk of weaning diarrhea. PMID:25175676

  14. Bile acids in radiation-induced diarrhea

    Radiation-induced bowel disease manifested by debilitating diarrhea is an unfortunate consequence of therapeutic irradiation for pelvic malignancies. Although the mechanism for this diarrhea is not well understood, many believe it is the result of damage to small bowel mucosa and subsequent bile acid malabsorption. Excess amounts of bile acids, especially the dihydroxy components, are known to induce water and electrolyte secretion and increase bowel motility. We have directly measured individual and total bile acids in the stool samples of 11 patients with radiation-induced diarrhea and have found bile acids elevated two to six times normal in eight of them. Our patients with diarrhea and increased bile acids in their stools had prompt improvement when given cholestyramine. They had fewer stools and returned to a more normal life-style

Introduction At the outset, I should like to acknowledge that part of the title above, which tries to capture the main flavour of this meeting, and has been borrowed from one of the plenary talks at the conference. When we set out to make the programme for the conference, we thought of beginning with observations on the Universe, but then we certainly wanted to go further and address deeper questions, which were at the very foundations of our inquiry, and understanding on the nature and structure of the Universe. I believe, we succeeded to a good extent, and it is all here for you in the form of these Conference Proceedings, which have been aptly titled as 'Vishwa Mimansa', which could be possibly translated as 'Analysis of the Universe'! It is my great pleasure and privilege to welcome you all to the ICGC-2011 meeting at Goa. The International Conference on Gravitation and Cosmology (ICGC) series of meetings are being organized by the Indian Association for General Relativity and Gravitation (IAGRG), and the first such meeting was planned and conducted in Goa in 1987, with subsequent meetings taking place at a duration of about four years at various locations in India. So, it was thought appropriate to return to Goa to celebrate the 25 years of the ICGC meetings. The recollections from that first meeting have been recorded elsewhere here in these Proceedings. The research and teaching on gravitation and cosmology was initiated quite early in India, by V V Narlikar at the Banares Hindu University, and by N R Sen in Kolkata in the 1930s. In course of time, this activity grew and gained momentum, and in early 1969, at the felicitation held for the 60 years of V V Narlikar at a conference in Ahmedabad, P C Vaidya proposed the formation of the IAGRG society, with V V Narlikar being the first President.

    Full Text Available Recent studies have revealed that microbes play an important role in the pathogenesis of gastrointestinal (GI diseases in various animal species, but only limited data is available about the microbiome in cats with GI disease. The aim of this study was to evaluate the fecal microbiome in cats with diarrhea. Fecal samples were obtained from healthy cats (n = 21 and cats with acute (n = 19 or chronic diarrhea (n = 29 and analyzed by sequencing of 16S rRNA genes, and PICRUSt was used to predict the functional gene content of the microbiome. Linear discriminant analysis (LDA effect size (LEfSe revealed significant differences in bacterial groups between healthy cats and cats with diarrhea. The order Burkholderiales, the families Enterobacteriaceae, and the genera Streptococcus and Collinsella were significantly increased in diarrheic cats. In contrast the order Campylobacterales, the family Bacteroidaceae, and the genera Megamonas, Helicobacter, and Roseburia were significantly increased in healthy cats. Phylum Bacteroidetes was significantly decreased in cats with chronic diarrhea (>21 days duration, while the class Erysipelotrichi and the genus Lactobacillus were significantly decreased in cats with acute diarrhea. The observed changes in bacterial groups were accompanied by significant differences in functional gene contents: metabolism of fatty acids, biosynthesis of glycosphingolipids, metabolism of biotin, metabolism of tryptophan, and ascorbate and aldarate metabolism, were all significantly (p<0.001 altered in cats with diarrhea. In conclusion, significant differences in the fecal microbiomes between healthy cats and cats with diarrhea were identified. This dysbiosis was accompanied by changes in bacterial functional gene categories. Future studies are warranted to evaluate if these microbial changes correlate with changes in fecal concentrations of microbial metabolites in cats with diarrhea for the identification of potential diagnostic or

    Full Text Available Objectives : This research examined about dietary therapy on the diarrhea based on the literary findings, for clinical treatment and prevention of the diarrhea. Methods : This Research examined on histories, compositions, applications, and effects of the diarrhea on about 100 cases of dietary therapy of the diarrhea from recent Chinese literatures Results : 1. Various vegetables, animals and mineral materials including herbs, grains, vegetables, fruits, food and drink were used for the dietary therapy. 2. Methods of the preparation for use as therapeutics were decoction, pulvis, gruel, medicinal wine, cake, tea, paste and gelatin and etc. 3. Frequently used materials were sesame oil, honey, ear mushroom, shiitake mushroom, kelp, walnut seed, hemp seed, groundnut, glutinous rice, apricot stone, yellow bean peel, radish, potato, spinage, and spring onion. Conclusion : Though dietary therapy for the diarrhea is not based on clinical or experimental data, but through experience. It is mostly based on Yin-Yang and five elements, visceral manifestation, channels and their collateral channels and chinese herbal medicine theories. If we use them properly according to oriental medicine method, it will be effective on treating and preventing the diarrhea.

  19. Opening Address

    Yamada, T.

    2014-12-01

    Ladies and Gentlemen, it is my great honor and pleasure to present an opening address of the 3rd International Workshop on "State of the Art in Nuclear Cluster Physics"(SOTANCP3). On the behalf of the organizing committee, I certainly welcome all your visits to KGU Kannai Media Center belonging to Kanto Gakuin University, and stay in Yokohama. In particular, to whom come from abroad more than 17 countries, I would appreciate your participations after long long trips from your homeland to Yokohama. The first international workshop on "State of the Art in Nuclear Cluster Physics", called SOTANCP, was held in Strasbourg, France, in 2008, and the second one was held in Brussels, Belgium, in 2010. Then the third workshop is now held in Yokohama. In this period, we had the traditional 10th cluster conference in Debrecen, Hungary, in 2012. Thus we have the traditional cluster conference and SOTANCP, one after another, every two years. This obviously shows our field of nuclear cluster physics is very active and flourishing. It is for the first time in about 10 years to hold the international workshop on nuclear cluster physics in Japan, because the last cluster conference held in Japan was in Nara in 2003, about 10 years ago. The president in Nara conference was Prof. K. Ikeda, and the chairpersons were Prof. H. Horiuchi and Prof. I. Tanihata. I think, quite a lot of persons in this room had participated at the Nara conference. Since then, about ten years passed. So, this workshop has profound significance for our Japanese colleagues. The subjects of this workshop are to discuss "the state of the art in nuclear cluster physics" and also discuss the prospect of this field. In a couple of years, we saw significant progresses of this field both in theory and in experiment, which have brought better and new understandings on the clustering aspects in stable and unstable nuclei. I think, the concept of clustering has been more important than ever. This is true also in the

    Full text: Honourable Representatives of His Majesty King Mohammed VI and of the Government of Morocco, representatives of sponsoring organizations, distinguished participants, on behalf of the Director General of the IAEA, it is my pleasure and privilege to welcome you to this International Conference on National Infrastructures for Radiation Safety: Towards Effective and Sustainable Systems. I would like to express my sincere appreciation to His Majesty King Mohammed VI for his patronage, to the Government of Morocco and the University Mohammed V, Agdal, for hosting this conference in the beautiful and historic city of Rabat, and to the local organizers for their diligent planning and gracious hospitality. I would also like to thank the four organizations that are co-operating with the IAEA in holding this conference: the World Health Organization, the Pan American Health Organization, the International Labour Organization, the European Commission and the OECD/Nuclear Energy Agency. National infrastructure for radiation safety has emerged as an issue of international concern over the last two decades. Systematic and strategic consideration of infrastructure has become widely recognized as an essential prerequisite for safety. The first IAEA conference to address the topic was in Munich, Germany, in 1990. The 1996 edition of the International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (known as the Basic Safety Standards or BSS) highlighted the issue, and the IAEA's technical co-operation Model Project for Upgrading Radiation Protection Infrastructure was introduced to help address it. The Model Project has helped, and continues to help, more than 85 IAEA Member States to work towards the goal of a radiation safety infrastructure in accordance with the Basic Safety Standards. A great deal has been achieved, but this work is not complete. Furthermore, not all States are members of the IAEA or the Model

  1. Opening address

    This opening address covers two main areas: first, a snapshot of the continuing threat and the recent changes having been made to the United Kingdom's counterterrorism structures to respond to it; and second, how the United Kingdom is combating nuclear terrorism through a range of measures covering physical security, decreasing vulnerability to attack and increasing resilience. Combating the threat of nuclear terrorism requires an international effort. Radiological and fissile materials are present throughout the world and, as such, it should be secured wherever it is found. All countries are encouraged to continue to enhance security and protection mechanisms for radiological and fissile material; and to develop contingency plans should the worst happen. The United Kingdom has responded to the very serious and real threat by consolidating and strengthening elements of its counterterrorist planning via the creation in May this year of the Office for Security and Counter-Terrorism (OSCT). These changes have been coupled with an unprecedented level of investment to enable the delivery of the United Kingdom counterterrorist strategy - known as CONTEST - through which we aim to (a) stop terrorist attacks; (b) where it cannot be stopped, to mitigate its impact; (c) strengthen our overall protection against terrorist attack; (d) stop people becoming terrorists or supporting violent extremism. In the case of radiological and nuclear terrorism, it is not sufficient merely to prepare for such an attack; one must also devote efforts to preventing such attacks in the first instance by intercepting dangerous materials before they reach their intended target; and by strengthening the protection of vulnerable places and detecting or mitigating any devices before they are placed or activated. As such, in terms of the United Kingdom's efforts on radiological and nuclear terrorism, there are three main strands to this work: physical protection of materials including the global

  2. Keynote address

    This keynote address describes the reasons why Ontario restructured its electricity sector to include open market competition. Much effort, time, money and expertise have been devoted to developing the Ontario competitive market. The 1997 White Paper issued by the Ontario Ministry of Energy, Science and Technology was the first paper to express the urgent need for change because the old system was failing. Prices increased by 60 per cent between 1986 and 1993. Although governments imposed a price freeze, it is recognized that such prices freezes cannot be sustained. Between 1980 and 1986, Ontario Hydro's debt rose from $12 billion to over $30 billion. The cause was attributed to poor business performance which was putting the taxpayers at risk. The author states that the potential and social benefits of competitive electricity markets are significant. Opening the power markets improves the efficiency of electricity systems and offers significant benefits. It is noted that restructuring does not mean deregulation. The Ontario Energy Board and the Independent Market Operator continue to regulate the market to ensure its proper operation and to protect consumers. In a properly functioning competitive market, prices change in response to market conditions. Electricity prices have generally declined where competitive markets have been introduced in other jurisdictions around the world. The author also cautions that it is easy to create unfounded fears about a competitive market and cited California as an example. California's problems arose from a lack of generating capacity, regulation which discouraged new power generation, inadequate transmission capacity, lack of snow in the northeast where hydropower is produced, and a consumer price cap that encouraged power consumption at a time when supply was short. The author notes that these factors do not exist in Ontario and that the competitive market should not be abandoned

    DOE biomass R ampersand D programs have the potential to provide America with both plentiful, clean-burning domestic transportation fuels and cost-competitive industrial and utility fuels, benefiting energy security in the United States. Biofuels developed under our programs will also help improve air quality, reduce greenhouse gases, reduce the large daily quantities of waste we produce, and revitalize rural America. These research motivations have been documented in the National Energy Strategy. DOE looks forward to expanding its biofuels research program and to forging a partnership with private sector for cost-shared commercialization of new fuels and vehicle technologies. Many alternative fuels (e.g., ethanol, methanol, compressed natural gas, propane, or electricity) are candidates for gaining market share. Indeed, there may be significant regional variation in the future fuel mix. Alcohol fuels from biomass, particularly ethanol, have the potential to make a major contribution. Currently, ethanol in the United States is almost entirely made from corn; and the limitations of that process are well known (e.g., costly feedstock, end product requiring subsidy to be competitive, use of fossil fuels in renewable feedstock production and processing, and potential adverse impact of corn ethanol production on the price of food). To address these concerns, the DOE biofuels program is pursuing an ambitious research program to develop the technologies needed to convert these crops into alternative transportation fuels, primarily cellulose-based ethanol and methanol. Program R ampersand D has reduced the estimated cost per gallon of cellulose-based ethanol from $3.60 in 1980 to the current $1.35, with a program goal of $0.60 by the year 2000. DOE is also investigating the thermochemical conversion of biomass to methanol. The program goal is to achieve commercial production of methanol (like ethanol) at the gasoline equivalent of $0.90 per gallon by the year 2000. 4 figs

    Nooroudien Mohamed; Monique Marais; Juanita Bezuidenhout

    2011-01-01

    AIM: To determine the prevalence of increased in-traepithelial lymphocytes, using immunohistochemistry in patients with normal colonoscopy and near normal biopsy. METHODS: We retrospectively reviewed all non-malig-nant colon mucosal biopsies between 2005 and 2007, reported as normal, chronic inflammation or melanosis coli in patients who were undergoing routine colonos-copy. Immunohistochemistry using CD3 was performed on all mucosal biopsies and an intraepithelial lympho-cyte count (IEL) was determined. Cases with an IEL count of ≥ 20 IELs per 100 surface epithelial cells were correlated with demographic, clinical and follow-up data. A further subgroup was evaluated for lymphocytic colitis.RESULTS: Twenty (8.3%) of 241 cases revealed an IEL count ≥ 20. Six (2.5%) patients were identified as having lymphocytic colitis (P < 0.001), of whom, five were missed on initial evaluation (P = 0.01). Four of these five patients were labeled with diarrhea-predom-inant irritable bowel syndrome (IBS). On follow-up, three of the remaining 20 cases were diagnosed with malignancy (renal cell carcinoma and myelodysplastic syndrome) and one had an unknown primary tumor with multiple liver metastases. Two cases of collag-enous colitis with an IEL count < 10 were included in this study. Increased IELs were not confined to pa-tients with diarrhea as a primary presenting symptom, but were also present in patients with abdominal pain (n = 7), constipation (n = 3) and loss of weight (n = 1). CONCLUSION: Immunohistochemistry using CD3 is of value in identifying and quantifying IELs for the pres-ence of microscopic colitis in patients with diarrhea-predominant IBS.

  5. Opening address

    The opening address by the host country started by thanking to the International Atomic Energy Agency for holding this important scientific event in in Morocco. The themes to be considered by this conference are among the priorities of the Scientific Research Department in its endeavour to promote scientific research in the field of nuclear science and technology for peaceful uses in Morocco. By so doing, this Department is following and supporting the efforts being made by our country to provide training, and elaborate rules and regulations, and to create infrastructure, acquire material and, equipment and encourage qualified and active researchers. Hence, the convening of this conference responds to a strategic interest of our country, which, similar to other countries, is committed to the achievement of comprehensive and sustainable development for the protection of human kind and the environment. This is considered nowadays as a strategic and vital objective as it entails the protection of people from radiation and against all kinds of professional risks and health hazards. Morocco attaches great importance to radiation safety issues. Our country adhered to all international conventions related to nuclear safety. It is in the process of adapting its internal regulations to international norms and standards, and it is making progress towards the establishment of a national safety body which meets those norms and standards, with the assistance of the IAEA. For this purpose, a standing committee for the follow-up of nuclear affairs has been created on the basis of Royal Instructions, and placed under the authority of the Prime Minister. Its task is to serve as a think-tank on nuclear safety issues and to make proposals on ways and means of reinforcing radiation safety measures. It goes without saying that the peaceful uses of nuclear energy must meet the safety standards elaborated by the IAEA. However, we are convinced that the elaboration of safety standards

    and become more technical. Involving experts from all fields is then crucial for success. This perception is reflected in the goals of this meeting. It is designed as an extensive information exchange forum between decision makers, regulators, radiation and waste safety specialists, and the nuclear industry. It is this mix which promises high efficiency with respect to solving the problems that you are addressing. I am sure that the safe termination of practices involving radioactive materials during the decommissioning of nuclear installations is one of the major challenges that industrialized nations will have to face during the next decades

  7. Welcome Address

    Kiku, H.

    2014-12-01

    Ladies and Gentlemen, It is an honor for me to present my welcome address in the 3rd International Workshop on "State of the Art in Nuclear Cluster Physics"(SOTANCP3), as the president of Kanto Gakuin University. Particularly to those from abroad more than 17 countries, I am very grateful for your participation after long long trips from your home to Yokohama. On the behalf of the Kanto Gakuin University, we certainly welcome your visit to our university and stay in Yokohama. First I would like to introduce Kanto Gakuin University briefly. Kanto Gakuin University, which is called KGU, traces its roots back to the Yokohama Baptist Seminary founded in 1884 in Yamate, Yokohama. The seminary's founder was Albert Arnold Bennett, alumnus of Brown University, who came to Japan from the United States to establish a theological seminary for cultivating and training Japanese missionaries. Now KGU is a major member of the Kanto Gakuin School Corporation, which is composed of two kindergartens, two primary schools, two junior high schools, two senior high schools as well as KGU. In this university, we have eight faculties with graduate school including Humanities, Economics, Law, Sciences and Engineering, Architecture and Environmental Design, Human and Environmental Studies, Nursing, and Law School. Over eleven thousands students are currently learning in our university. By the way, my major is the geotechnical engineering, and I belong to the faculty of Sciences and Engineering in my university. Prof. T. Yamada, here, is my colleague in the same faculty. I know that the nuclear physics is one of the most active academic fields in the world. In fact, about half of the participants, namely, more than 50 scientists, come from abroad in this conference. Moreover, I know that the nuclear physics is related to not only the other fundamental physics such as the elementary particle physics and astrophysics but also chemistry, medical sciences, medical cares, and radiation metrology

    Nuclear terrorism has been recognized as a potential threat to human security and economic prosperity since at least the 1970s. Evidence of Al Qaeda's interest in acquiring nuclear material came to light during the 1990s. However, it is since the attacks of 11 September 2001 that the risk of nuclear terrorist acts has come to be a widespread public and governmental concern, for understandable reasons, and that efforts to combat illicit trafficking, which could lead to nuclear or other radioactive materials falling into the hands of terrorists, have intensified. Six years on, it makes sense to take stock of what has been achieved in the combat to stem illicit trafficking and of where further actions - actions of individual States and cooperative international actions - might usefully be initiated. The IAEA has maintained an Illicit Trafficking Database since 1995. Information reported to this database confirms that concerns about illicit trafficking in nuclear material are justified. Database information points to persistent theft and loss of radioactive sources. States' international obligations relevant to international nuclear trafficking are based on the Convention on the Physical Protection of Nuclear Material (CPPNM), the International Convention for the Suppression of Acts of Nuclear Terrorism, the United Nations Security Council Resolution 1540, which deals with weapons of mass destruction, including nuclear weapons and non-State actors, and the United Nations Security Council Resolution 1375, which requires all States to take the necessary steps to prevent the commission of terrorist acts, including early warning to other States. In addition to these legally binding instruments, there is the non-binding Code of Conduct on the Safety and Security of Radioactive Sources, which Member States of the IAEA agreed in 2003. The Code addresses the establishment of an adequate system of regulatory control, from the production of radioactive sources to their final

    Full Text Available Abstract Background Prevention of diarrhea has presented indomitable challenges. A preventive strategy that has received significant interest is zinc supplementation. Existing literature including quantitative meta-analyses and systematic reviews tend to show that zinc supplementation is beneficial however evidence to the contrary is augmenting. We therefore conducted an updated and comprehensive meta-analytical synthesis of the existing literature on the effect of zinc supplementation in prevention of diarrhea. Methods EMBASE®, MEDLINE ® and CINAHL® databases were searched for published reviews and meta-analyses on the use of zinc supplementation for the prevention childhood diarrhea. Additional RCTs published following the meta-analyses were also sought. Effect of zinc supplementation on the following five outcomes was studied: incidence of diarrhea, prevalence of diarrhea, incidence of persistent diarrhea, incidence of dysentery and incidence of mortality. The published RCTs were combined using random-effects meta-analyses, subgroup meta-analyses, meta-regression, cumulative meta-analyses and restricted meta-analyses to quantify and characterize the role of zinc supplementation with the afore stated outcomes. Results We found that zinc supplementation has a modest beneficial association (9% reduction with incidence of diarrhea, a stronger beneficial association (19% reduction with prevalence of diarrhea and occurrence of multiple diarrheal episodes (28% reduction but there was significant unexplained heterogeneity across the studies for these associations. Age, continent of study origin, zinc salt and risk of bias contributed significantly to between studies heterogeneity. Zinc supplementation did not show statistically significant benefit in reducing the incidence of persistent diarrhea, dysentery or mortality. In most instances, the 95% prediction intervals for summary relative risk estimates straddled unity. Conclusions Demonstrable

    Being fully aware of the IAEA's central and important roles in the field of nuclear security, Japan has cooperated closely with the IAEA in the field of nuclear security. One of Japan's efforts was holding a seminar on strengthening nuclear security in Asian countries in November 2006, making use of Japan's contribution to the IAEA Nuclear Security Fund. The seminar was organized for the first time in Asia to address nuclear security matters, in which more than 100 experts from 19 countries participated. Japan also hosted a seminar, aimed at promoting the accession to the international counterterrorism conventions and protocols, inviting government officials and experts from Asia Pacific countries. At the seminar, Japan presented its experience and lessons learned with regard to its ratification of relevant international conventions such as the International Convention for the Suppression of Acts of Nuclear Terrorism and the Convention on the Physical Protection of Nuclear Material. Japan has also provided assistance for capacity building in the field of physical protection measures, and is preparing three projects for Asian countries through the IAEA Nuclear Security Fund. In Thailand, Japan has a project aimed at improving physical protection of nuclear research facilities. In Vietnam, Japan plans to host a workshop on radiation detection equipment for border officials and is also preparing for a seminar aimed at capacity building of control on nuclear material in Vietnam. Japan is committed to continue its efforts to make the IAEA Comprehensive Safeguards Agreement together with an Additional Protocol the universally accepted verification standard for the peaceful use undertakings of the Nuclear Non-Proliferation Treaty. Japan's basic policy on bilateral nuclear cooperation agreements is as follows. Considering the dual nature of nuclear material and technology, Japan is of the view that three Ss, that is, S for 'safeguards' (non-proliferation), S for 'safety

  11. Probiotics for Infectious Diarrhea and Traveler's Diarrhea - What Do We Really Know?

    Hibberd, Patricia L.

    Worldwide, diarrhea is the sixth leading cause of premature death (Lopez et al., 2006), accounting for more than two million deaths each year. The majority of the burden is borne in lower and middle income countries, and in children under age 5 (Kosek et al., 2003). Even in the United States where there is easy access to “safe” food and water, there are an estimated 211-375 million episodes of acute diarrhea each year, resulting in 900,000 hospitalizations and 6,000 deaths (Herikstad et al., 2002; Mead et al., 1999). While mortality from diarrhea has decreased over the last 30 years, the incidence and morbidity associated with diarrhea has not improved (Kosek et al., 2003). During the same time period an ever increasing number of enteric pathogens as well as non-infectious conditions have been recognized as causes of acute diarrhea (Guerrant et al., 2001).

  12. Diarrheal Illness and Healthcare Seeking Behavior among a Population at High Risk for Diarrhea in Dhaka, Bangladesh.

    Fahima Chowdhury

    Full Text Available Diarrhea remains one of the major causes of death in Bangladesh. We studied diarrheal disease risk and healthcare seeking behavior among populations at high risk for diarrhea in Dhaka, Bangladesh. Data were obtained from a cross-sectional survey conducted during April and September 2010. The prevalence of diarrhea was calculated by age-group and sex. A generalized estimating equation with logit link function was used to predict diarrheal disease risk and seeking care from a professional healthcare provider. Of 316,766 individuals, 10% were young children (<5 years. The prevalence of diarrhea was 16 per 1000 persons among all ages; young children accounted for 44 per 1000 persons. Prevalence of diarrhea was significantly higher (p=.003 among younger males (<15 years compared to that among younger females. In contrast, prevalence of diarrhea was significantly higher (p<.0001 among older females (≥15 years compared to that among older males. An increased risk for diarrhea was observed in young children, males, and those staying in rented houses, lower family members in the house, using non-sanitary toilets, living in the area for short times, living in a community with less educated persons, living in a community with less use of safe water source for drinking, or living close to the hospital. About 80% of those with diarrhea sought care initially from a non-professional healthcare provider. Choice of the professional healthcare provider was driven by age of the patient, educational status of the household head, and hygienic practices by the household. The study reaffirms that young children are at greater risk for diarrhea. Like other developing countries most people in this impoverished setting of Dhaka are less likely to seek care from a professional healthcare provider than from a non-professional healthcare provider, which could be attributed to a higher number of diarrheal deaths among young children in Bangladesh.

    2002-01-01

    Chronic, antibiotic-resistant pneumonia, sometimes with concurrent polyarthritis, occurs in feedlot cattle in western Canada. The prevalence of Mycoplasma bovis, bovine viral diarrhea virus, and Haemophilus somnus was determined by using immunohistochemical staining of lung and heart tissue from 2 groups of animals with this history. Mycoplasma bovis antigen was present in 44/48 cases submitted between 1995 and 1998 (retrospective group) and 15/16 of cases from 1999 (prospective group), and w...

  16. Molecular characterization of rotavirus isolated from alpaca (Vicugna pacos) crias with diarrhea in the Andean Region of Cusco, Peru.

    Garmendia, Antonio E; Lopez, Wellington; Ortega, Nastassja; Chamorro, Marycris J

    2015-10-22

    Alpacas (Vicugna pacos), a species of South American camelids (SAC), suffer high morbidity and mortality from infectious diseases. Diarrhea is one of the leading causes of alpaca cria mortality in Peru and elsewhere. In order to develop appropriate control and/or treatment, it is necessary to identify infectious pathogens that cause diarrhea in crias. Rotavirus was isolated in cell culture from feces collected from crias with acute diarrhea that tested positive to rotaviral antigen by rapid immunochromatographic methods in an earlier study. The isolates were identified as rotaviruses by RT-PCR run with specific primers for human rotavirus VP7 coding sequences using total RNA extracted from cells displaying cytopathic effects as template. These alpaca isolates were further identified as group A rotaviruses by means of a VP6-specific PCR and were designated as ALRVA-K'ayra/Perú/3368-10 and ALRVA-K'ayra/Perú/3386-10. Molecular G and P typing, placed the former as G3/P11 and the latter as G3/P?. Sequence analysis of two genome segments (coding for VP4 and VP7) from the alpaca isolates revealed partial homologies to swine and human rotaviruses, respectively. These results demonstrate that rotaviruses are associated with a proportion of cases of diarrhea in crias, although prevalence and impact remain to be determined. The isolation of rotaviruses from alpaca crias with diarrhea will contribute positively to further understand the pathogen and its role in the diarrhea complex. PMID:26243695

    Piglet diarrhea epidemics result in major economic losses for the swine industry. Four viruses are closely linked to porcine diarrhea: porcine kobuvirus (PKV), porcine epidemic diarrhea virus (PEDV), porcine transmissible gastroenteritis virus (TGEV), and porcine rotavirus (PRoV). We have conducted an epidemiology study to determine the frequency of infection and co-infection with these viruses in China, and characterized the genetic variation of the isolated PEDV and PKV strains. Stool and intestinal samples (n = 314) were collected from piglets with diarrhea in China from years 2012 to 2014. RT-PCR was used to detect PKV, PEDV, TGEV, and PRoV. Phylogenetic relationships between reference strains and the isolated PEDV and PKV strains were determined based on the M and 3D gene sequence. The rates of infection with PKV, PEDV, TGEV and PRoV were 29.9%, 24.2%, 1.91%, and 0.31%, respectively. Co-infections with PKV and the other three viruses were very common. Co-infection of PKV and PEDV was detected in 15.0% (47/314) of the samples. Phylogenetic analysis of the PKV 3D gene indicated that there were some phylogenetic differences in the PKV strains across regions within China. However, according to the PEDV M gene, strains clustered into three groups and the primary group was distinct from the vaccine strain CV777. This study provides insights in to the prevalence of diarrhea viruses and their prevention and control in China. PMID:26982468

  2. α1,2-Fucosyllactose Does Not Improve Intestinal Function or Prevent Escherichia coli F18 Diarrhea in Newborn Pigs

    Cilieborg, Malene Skovsted; Sangild, Per Torp; Jensen, Michael Ladegaard;

    2016-01-01

    OBJECTIVES:: Infectious diarrhea, a leading cause of morbidity and deaths, is less prevalent in breast-fed infants compared with infants fed infant formula. The dominant human milk oligosaccharide (HMO), α-1,2-fucosyllactose (2’-FL), has structural homology to bacterial adhesion sites in the...... intestine and may in part explain the protective effects of human milk. We hypothesized that 2’-FL prevents diarrhea via competitive inhibition of pathogen adhesion in a pig model for sensitive newborn infants. METHODS:: Intestinal cell studies were coupled with studies on cesarean-delivered newborn pigs (n...

  3. Cryptosporidiosis Among HIV-infected Patients with Diarrhea in Edo State, Midwesten Nigeria

    Akinbo, F. O.

    2010-01-01

    Full Text Available To determine the prevalence of cryptosporidiosis among HIV infected and HIV non-infected patients with diarrhea in Edo State, Nigeria, as well as the effect of CD4+ lymphocyte count on the prevalence of cryptosporidial infection among the HIV patients. Stool samples were collected from 300 patients consisting of 200 HIV-infected and 100 HIV non-infected patients with diarrhea. Blood samples were collected from the HIV-infected patients. The stool samples were processed to detect Cryptosporidium species using a modified Ziehl-Neelsen stain, as well as other intestinal parasites using saline and iodine preparations. The blood samples were used to determine CD4+ lymphocyte count. The prevalence of intestinal parasites was higher in HIV-infected patients compared with their HIV non-infected counterparts (39% vs 24% respectively, p=0.0097. Cryptosporidiosis was diagnosed only among HIV-infected patients and was the only parasite whose prevalence was significantly different between HIV-infected and HIV non-infected patients. CD4+ lymphocyte count of <200 cells/µL among HIV-infected was a risk factor for acquiring cryptosporidial infection (OR=18.776, 95% CI=6.299, 55.964. A cryptosporidial infection prevalence of 18% among HIV-infected patients was observed and CD4+ count of <200 cells/µL was a risk factor for acquiring the disease. Routine examination of diarrhogenic stools of HIVinfected patients for cryptosporidiosis is advocated.

    Objective: To determine the frequency and clinical features of Rota virus diarrhea in children presenting in a tertiary care hospital. Study Design: A cross-sectional, observational study. Place and Duration of Study: National Institute of Child Health, Karachi, from January to June 2007. Methodology: A total of three hundred children of either gender aged 1 month to 5 years, who presented with diarrhea of < 7 days as a primary illness were enrolled. Children with bloody diarrhea or nosocomial gastroenteritis acquired during hospitalization for other disease were not included. Detection of Rota virus in stool was done by enzyme linked immunoassay. Results: Out of 300 children, 188 (63%) tested positive and 112 (37%) tested negative for Rota virus. Positive Rota virus cases in 7 - 12 months of age was (n = 34, 18.08%). Overall, 151 (80.3%) children with Rota virus were less than 3 years old. 182 (60.7%) had fever, 118 (39.3%) had vomiting and 156 (82.9%) children had both fever and vomiting. Conclusion: This study shows that Rota virus is a common organism causing diarrhea in children less than 3 years of age. There is a need to incorporate Rota virus vaccine in the national EPI program to decrease the disease burden as highlighted in this study. (author)

  8. Refractory diarrhea: A paraneoplastic syndrome of neuroblastoma.

    Han, Wei; Wang, Huan-Min

    2015-07-01

    Neuroblastoma (NB) is the most common extracranial solid tumor in children. Diarrheal NB is quite rare and is not easy to diagnose in the early stage. Six cases of diarrheal NB in our hospital treated from 1996 to 2006 were retrospectively analyzed, including characteristics such as electrolyte imbalance, pathologic features, vasoactive intestinal peptide (VIP) immunohistochemical staining results, treatment, and prognosis. All patients were boys with 3-8 loose or watery stools each day and routine fecal tests were normal. Abdominal tumors were identified by B-ultrasound. Drugs were ineffective. Three patients underwent surgery, and the remaining three patients received surgery and chemotherapy. Diarrhea stopped after treatment in five patients. Two patients died due to intractable hypokalemia. The tumor was located in the adrenal gland in four patients, in the upper retroperitoneum in one patient, and in the presacral area in one patient. Pathologic findings were NB and ganglioneuroblastoma. Five patients were at clinical stage I-II, and one was at stage III. Four patients survived (followed-up for 6 mo to 4 years). Immunohistochemical staining for VIP was positive. Refractory diarrhea is a paraneoplastic syndrome of NB and is rare. Patients aged 1-3 years who present with chronic intractable diarrhea should be followed closely. Intractable diarrhea, hypokalemia, and dysplasia are the initial clinical manifestations. Increased VIP is characteristic of this disease. Potassium supplementation plays a vital role in the treatment procedure, especially preoperatively. The prognosis of diarrheal NB is good following appropriate treatment. PMID:26167095

    2016-01-01

    Full Text Available BACKGROUND Hypersecretory state of gut epithelium induced by toxins secreted by microorganisms is the main mechanism of fluid loss in diarrheal illness. Enkephalins (Endogenous Opioids secreted by gut epithelium have marked pro-absorptive activity and are inactivated by enzyme enkephalinase. Racecadotril, the study drug act by augmenting the levels of enkephalins by inactivating enzyme enkephalinase thus leading to increased intestinal absorption. AIMS AND OBJECTIVES To study the efficacy of racecadotril in acute watery diarrhea in children. PARTICIPANTS Total of 100 patients who met inclusion criteria in the age group of 6 months to 5 years admitted with acute watery diarrhea and some dehydration were enrolment in the study. Cases were randomly divided into racecadotril and placebo group study outcomes in form of number of stools during first 48 hours of admission, mean daily stool number, total duration of diarrheal illness and recovery time, weight on discharge, volume of oral rehydration solution intake during hospital stay and requirement for unscheduled intravenous infusion were observed. RESULTS There was a significant decrease (43.9% in mean number of stools passed per day in racecadotril group when compared to placebo group. Secondary outcome variables, i.e. mean daily stool number, duration of diarrhea and recovery time, total volume of oral rehydration solution during study period, requirement for unscheduled intravenous infusion also showed a statically significant difference in two groups. Complications rates were not different in the two groups. CONCLUSION Racecadotril can be used as an adjunctive therapy in acute watery diarrhea

    The effect of origin and destination country on traveler's diarrhea incidence rates in Southeast Asia is poorly understood, and research generally only addresses diarrhea in travelers from the developed world. This study evaluated the attack rate and effects of traveler's diarrhea by origin and destination and analyzed key risk factors. A self-administered questionnaire was provided to foreign travelers departing Southeast Asia from Suvarnabhumi Airport, Bangkok, Thailand. It evaluated traveler demographics, relevant knowledge and practices, experiences of diarrhea, and the details and consequences of each diarrheal episode. A total of 7,963 questionnaires were completed between April 2010 and July 2011. Respondents were 56% male (mean age 35) with a mean and median duration of stay of 28 days and 10 days, respectively. Most respondents were from Europe (36.8%) or East Asia (33.4%). The attack rate of traveler's diarrhea was 16.1%, with an incidence rate of 32.05 per 100 person months. Travelers' origin and destination countries significantly related to diarrhea risk. Oceanians had the highest risk (32.9%) and East Asians the lowest (2.6%). Vietnam and Indonesia were the highest risk destinations (19.3%). Other significant factors were youth, trip duration, number of countries visited, and frequently drinking beverages with ice.

    AIM: To search the pathophysiological mechanism of diarrhea based on daily stool weights, fecal electrolytes,osmotic gap and pH.METHODS: Seventy-six patients were included: 51 with microscopic colitis (MC) [40 with lymphocytic colitis (LC);11 with collagenous colitis (CC)]; 7 with MC without diarrhea and 18 as a control group (CG). They collected stool for 3 d. Sodium and potassium concentration were determined by flame photometry and chloride concentration by titration method of Schales. Fecal osmotic gap was calculated from the difference of osmolarity of fecal fluid and double sum of sodium and potassium concentration.RESULTS: Fecal fluid sodium concentration was significantly increased in LC 58.11±5.38 mmol/L (P<0.01)and CC 54.14±8.42 mmol/L (P<0.05) than in CG 34.28±2.98 mmol/L. Potassium concentration in LC 74.65±5.29 mmol/L (P<0.01) and CC 75.53±8.78 mmol/L (P<0.05) was significantly less compared to CG 92.67±2.99 mmol/L.Chloride concentration in CC 36.07±7.29 mmol/L was significantly higher than in CG 24.11±2.05 mmol/L (P<0.05).Forty-four (86.7%) patients had a secretory diarrhea compared to fecal osmotic gap. Seven (13.3%) patients had osmotic diarrhea.CONCLUSION: Diarrhea in MC mostly belongs to the secretory type. The major pathophysiological mechanism in LC could be explained by a decrease of active sodium absorption. In CC, decreased Cl/HCO3 exchange rate and increased chloride secretion are coexistent pathways.

    Hannaoui, Erika; Villalobos, Luz; Martínez, Rosa; Maldonado, Antonio; Hagel, Isabel; Bastardo, Jesús

    2010-12-01

    To establish the prevalence of strains of diarrheagenic Escherichia coli (DEC) associated to acute diarrhea in children of Cumaná, Venezuela, stool samples were taken from 200 children aged ADEC). From 169 E. coli, isolates we determined by PCR 10.65% positive for EPEC (1.18% "typical", 9.47% "atypical"); ETEC (5.91%); EAEC (1.78 %), EIEC (0.59%). There were no statistically significant differences regarding the frequency of each "pathotype" in relation to age, but it did occur when related to the sex (p<0.05). The most relevant clinical features were: fever, vomiting and abdominal pain and the greatest percentage of children affected were of the working and marginal classes. These results shown that the strains of DEC are important etiological agents in acute infectious diarrhea in children of Cumaná. PMID:21365876

    Full Text Available Zinc supplementation is a critical new intervention for treating diarrheal episodes in children. Recent studies suggest that administration of zinc along with new low osmolarity oral rehydration solutions / salts (ORS, can reduce the duration and severity of diarrheal episodes for up to three months. The World Health Organization (WHO and UNICEF recommend daily 20 mg zinc supplements for 10 - 14 days for children with acute diarrhea, and 10 mg per day for infants under six months old, to curtail the severity of the episode and prevent further occurrences in the ensuing -two to three months, thereby decreasing the morbidity considerably. This article reviews the available evidence on the efficacy and safety of zinc supplementation in pediatric diarrhea and convincingly concludes that zinc supplementation has a beneficial impact on the disease outcome.

    Full Text Available Prophylactic zinc supplementation has been shown to reduce diarrhea and respiratory illness in children in many developing countries, but its efficacy in children in Africa is uncertain.To determine if zinc, or zinc plus multiple micronutrients, reduces diarrhea and respiratory disease prevalence.Randomized, double-blind, controlled trial.Rural community in South Africa.THREE COHORTS: 32 HIV-infected children; 154 HIV-uninfected children born to HIV-infected mothers; and 187 HIV-uninfected children born to HIV-uninfected mothers.Children received either 1250 IU of vitamin A; vitamin A and 10 mg of zinc; or vitamin A, zinc, vitamins B1, B2, B6, B12, C, D, E, and K and copper, iodine, iron, and niacin starting at 6 months and continuing to 24 months of age. Homes were visited weekly.Primary outcome was percentage of days of diarrhea per child by study arm within each of the three cohorts. Secondary outcomes were prevalence of upper respiratory symptoms and percentage of children who ever had pneumonia by maternal report, or confirmed by the field worker.Among HIV-uninfected children born to HIV-infected mothers, median percentage of days with diarrhea was 2.3% for 49 children allocated to vitamin A; 2.5% in 47 children allocated to receive vitamin A and zinc; and 2.2% for 46 children allocated to multiple micronutrients (P = 0.852. Among HIV-uninfected children born to HIV-uninfected mothers, median percentage of days of diarrhea was 2.4% in 56 children in the vitamin A group; 1.8% in 57 children in the vitamin A and zinc group; and 2.7% in 52 children in the multiple micronutrient group (P = 0.857. Only 32 HIV-infected children were enrolled, and there were no differences between treatment arms in the prevalence of diarrhea. The prevalence of upper respiratory symptoms or incidence of pneumonia did not differ by treatment arms in any of the cohorts.When compared with vitamin A alone, supplementation with zinc, or with zinc and multiple

    Diarrhea affecting infants and children is an important primary-care problem. Most winter infections are caused by rotavirus, but newer viral, bacterial and protozoan pathogens have been discovered. Fluid and electrolyte therapy is the mainstay of therapy. Antiemetic, antibiotic and antidiarrheal medications can usually be avoided. Commercial clear fluid products have been reformulated to allow effective rehydration and maintenance of hydration, thus avoiding hospitalization or use of intrave...

  19. Probiotics for Prevention and Treatment of Diarrhea.

    Guarino, Alfredo; Guandalini, Stefano; Lo Vecchio, Andrea

    2015-01-01

    Probiotics are increasingly used for prevention and treatment of diarrhea more in children than in adults. Given the broad spectrum of diarrhea, this review focuses on the main etiologies: acute gastroenteritis, antibiotic-associated diarrhea (AAD), and necrotizing enterocolitis (NEC). For each, we reviewed randomized controlled trials, meta-analyses, and guidelines. For acute gastroenteritis we found 12 guidelines: 5 recommended probiotics and 7 did not. However, the guidelines containing positive recommendations provided proof of evidence from clinical trials and meta-analyses. Lactobacillus rhamnosus GG (LGG) and Saccharomyces boulardii had the most compelling evidence of efficacy as they reduced the duration of the disease by 1 day. For AAD 4 meta-analyses were found, reporting variable efficacy of probiotics in preventing diarrhea, based on the setting, patient's age, and antibiotics. The most effective strains were LGG and S. boulardii. For NEC, we found 3 randomized controlled trials, 5 meta-analyses, and 4 position papers. Probiotics reduced the risk of NEC enterocolitis and mortality in preterm babies. Guidelines did not support a routine use of probiotics and asked for further data for such sensitive implications. In conclusion, there is strong and solid proof of efficacy of probiotics as active treatment of gastroenteritis in addition to rehydration. There is solid evidence that probiotics have some efficacy in prevention of AAD, but the number needed to treat is an issue. For both etiologies LGG and S. boulardii have the strongest evidence. In NEC the indications are more debated, yet on the basis of available data and their implications, probiotics should be carefully considered. PMID:26447963

    Traveler's diarrhea is a very common condition that affects approximately 12 million subjects each year. This disorder is benign but nevertheless interferes with the traveler's plans in 40% of cases. Several drugs have been used for prophylaxis, in association with appropriate precautions concerning food and drink. Trimethoprim-sulfamethoxazole and cyclines are effective but may induce adverse effects. Nifuroxazide in a dose of 400 mg each day throughout the trip has proved effective. Tolerance was outstanding with no adverse effects. PMID:3534765

  2. Caregiver recognition of childhood diarrhea, care seeking behaviors and home treatment practices in rural Burkina Faso: a cross-sectional survey.

    Shelby E Wilson

    Full Text Available INTRODUCTION: To design effective national diarrhea control programs, including oral rehydration solution (ORS and therapeutic zinc supplementation, information is needed on local perceptions of illness, external care seeking behaviors, and home treatment practices. METHODS: A cross-sectional, community-based household survey was conducted in the Orodara Health District, Burkina Faso. Caregivers of 10,490 children <27 months were interviewed to assess child diarrhea prevalence and related care practices. Characteristics of households, caregivers, children, and reported illnesses were compared for those caregivers who did or did not recognize the presence of diarrhea, as defined according to clinical criteria (≥ 3 liquid or semi-liquid stools/day. Multiple logistic regression models were used to examine factors associated with illness recognition and treatment. RESULTS: Clinically defined diarrhea was present in 7.6% (95% CI: 7.1-8.1% of children during the 24 hours preceding the survey but recognized by only 55% of caregivers. Over half (55% of the caregivers of 1,067 children with a clinically defined diarrhea episode in the past 14 days sought care outside the home; 78% of those seeking care attended a public sector clinic. Care was sought and treatment provided more frequently for children with fever, vomiting, anorexia, longer illness duration, and those living closer to the health center; and care was sought more frequently for male children. 80% of children with recent diarrhea received some form of treatment; only 24% received ORS, whereas 14% received antibiotics. Zinc was not yet available in the study area. CONCLUSIONS: Caregivers frequently fail to recognize children's diarrhea, especially among younger infants and when illness signs are less severe. Treatment practices do not correspond with international recommendations in most cases, even when caregivers consult with formal health services. Child caregivers need additional

  3. Developing a scorecard to assess global progress in scaling up diarrhea control tools: a qualitative study of academic leaders and implementers.

    Alexander Anthony Rosinski

    Full Text Available BACKGROUND: In 2010, diarrhea caused 0.75 million child deaths, accounting for nearly 12% of all under-five mortality worldwide. Many evidence-based interventions can reduce diarrhea mortality, including oral rehydration solution (ORS, zinc, and improved sanitation. Yet global coverage levels of such interventions remain low. A new scorecard of diarrhea control, showing how different countries are performing in their control efforts, could draw greater attention to the low coverage levels of proven interventions. METHODS: We conducted in-depth qualitative interviews with 21 experts, purposively sampled for their relevant academic or implementation expertise, to explore their views on (a the value of a scorecard of global diarrhea control and (b which indicators should be included in such a scorecard. We then conducted a ranking exercise in which we compiled a list of all 49 indicators suggested by the experts, sent the list to the 21 experts, and asked them to choose 10 indicators that they would include and 10 that they would exclude from such a scorecard. Finally, we created a "prototype" scorecard based on the 9 highest-ranked indicators. RESULTS: Key themes that emerged from coding the interview transcripts were: a scorecard could facilitate country comparisons; it could help to identify best practices, set priorities, and spur donor action; and it could help with goal-setting and accountability in diarrhea control. The nine highest ranking indicators, in descending order, were ORS coverage, rotavirus vaccine coverage, zinc coverage, diarrhea-specific mortality rate, diarrhea prevalence, proportion of population with access to improved sanitation, proportion with access to improved drinking water, exclusive breastfeeding coverage, and measles vaccine coverage. CONCLUSION: A new scorecard of global diarrhea control could help track progress, focus prevention and treatment efforts on the most effective interventions, establish transparency and

    Full Text Available Shigellosis is an important public health problem, especially in developing countries. Antibiotic treatment of bacterial dysentery, aimed at resolving diarrhea or reducing its duration is especially indicated whenever malnutrition is present. First-line drugs include ampicillin and trimethoprim sulfamethoxazole(TMP-SMX; however multidrug-resistance has occurred and careful antibiotic selection must be considered in prescribing .When epidemiologic data indicate a rise in resistancy, fluoroquinolones may be used in adults and oral third-generation cephalosporins and nalidixic acid in children. All children (n=2400 with acute diarrhea who were admitted to the Pediatric department of Dr.sheykh Hospital Mashhad, Iran from March 2004 to March 2005 were selected and their stool culture were obtained, then positive cultures (312 cases,13% were evaluated by antibiogram. This study showed that in heavily populated areas of IRAN like Mashhad, 97% shigella strain isolated from children with bloody diarrhea were sensitive to nalidixic acid, ciprofloxacin and cefixime and rarely susceptible to ampicillin and cotrimoxazole. There is increasing resistance of Shigella to most of the antibiotics in use, and for this reason, careful selection of antibiotics must use considered in each area. Development and use of new drugs are expensive and have severe limitations in the third world. Simple prophylactic alternatives are therefore, required, such as awareness of hygienic child care practices and early promotion of breast feeding. For treatment of shigellosis in infants Ceftriaxon, and in children Nalidixic Acid is recommended.

  5. [Antibiotic-associated diarrhea in clinical practice].

    Luzina, E V; Lareva, N V

    2013-01-01

    Antibiotic-associated diarrhea (AAD) is considered to mean at least 3 shapeless stool episodes within 2 or more consecutive days when using antibacterial agents. Due to the fact that antibiotics are used most commonly to treat many diseases, AAD is one of the topical problems for different clinical specialists. There has recently been increased interest in this condition due to its higher morbidity and mortality rates and the emergence of novel treatment-resistant virulent strains of Clostridium difficile 027 and 078/126. The paper discusses the possible risk of developing AAD depending on the class of the antibiotic used, as well as the mechanisms of its development. Infectious diarrhea most frequently results from bacterial overgrowth due to that the obligate intestinal microflora is suppressed by antibacterial drugs. C. difficile, Clostridium perfringers, Staphylococcus aureus, Salmonella spp., Klebsiella oxytoca, and Candida spp. are etiological factors in the development of this diarrhea. The severest intestinal lesions include pseudomembranous colitis (PMC) caused by C. difficile. The clinical and endoscopic picture and methods for the diagnosis and treatment of PMC are described. Therapy for this menacing condition is traditionally based on the use of metronidazole and vancomycin. In 2011, the US Food and Drug Administration approved the new drug fidaxomycin whose superiority over vancomycin has been demonstrated by a recurrence criterion. The paper discusses in detail other treatment options, including the use of probiotics. PMID:23653946

  6. Chronic diarrhea. Diagnosis and clinical evaluation

    Chronic diarrhea is a syndrome of great clinical complexity, which is frequently encountered by general physicians, internists and gastroenterologists. Differential diagnosis is very broad and sometime finding the precise cause can be difficult, expensive and frustration. Literature published about this topic lack, in general, adequate controlled studies and for this reason recommendations for diagnostic evaluation and treatment are based upon series of cases, experience of the institutions or expert opinion and not on reasonable evidence. On the other hand, many of the classical diagnostic tests that have survived until now were designed over physiologic foundations and have not been validated extensively with the precision of a clinical test. This limits its acceptance, application and standardization in the daily practice. There is not a general agreement about diagnosis and treatment of chronic diarrhea and many of the experts divert recommendation about their recommendations. The purpose of this paper is to define some general guidelines about the clinical evaluation of patients with chronic diarrhea that lead us to a rational approach based upon clinical trials and the appropriate use of the many different tests

  7. Management of chemotherapy induced diarrhea (abstract)

    Diarrhoea is seen with many tumors and following several chemotherapy regimen esp. those containing 5-fluorouracil and high dose folinic acid it causes debility even death, delays cancer treatment, reduces compliance increases cost. It causes dehydration, renal failure volume depletion. Quality of life is worsened and hospitalization may be needed in multifactorial, with secretion; absorption imbalance due to mucosal damage, necrosis or inflammation. Local infection is set up by opportunistic organism and cell necrosis. The large volume of fluid and electrolytes overwhelms colonic absorptive capacity. Agent usually used for treatment is opioids (such as Diphenoxylate / Loperamide]. Bismuth (for inflammatory diarrhea). NSAIDs or alpha 2-agonists. For optimal management, the cause and severity should be assessed and treatment planned. Advice is given about certain dietary restraints and avoidance of some drugs. Fever, infection, dehydration and electrolyte losses are treated, pain relieved. Diphenoxylate / Loperamide (later is more effective; 4 mg, STAT, then 2mg every 4 hours or even 2 hourly) may be used. It is moderately effective in CID. Octreotide is useful in carcinoid. VIPoma, AIDS idiopathic secretary diarrhea, ileostomy, dumping syndrome. It acts directly on epithelial cells to reduce secretin, motilin pancreatic polypeptide. It slows transit time, reduces fluid and electrolyte secretin, increases absorption of electrolytes. It is effective in 5 FU and high dose chemotherapy with a 90% response rates seen after 3 days treatment. High Dose Chemotherapy and total body irradiation - induced diarrhea usually resolves within 72 hours. (author)

    2015-03-01

    Full Text Available Background Diarrhea is one of the major causes of morbidity and mortality in children throughout the world, mostly due to rotavirus infection. In daily practice, we routinely use the World Health Organization Five steps for managing acute diarrhea.This practice has shown great success in diarrhea management, but concerns remain on reducing the duration of diarrhea to prevent complications. Synbiotics can reduce the severity of diarrhea. However, there has been limited data on synbiotic therapy for treating acute rotavirus diarrhea in children. Objective To compare the durations of acute rotavirus diarrhea treated with synbiotics vs. placebo. Methods This study was a randomized, double-blind, clinical trial, performed at the Pediatric Gastrohepatology Division, Sanglah and Wangaya Hospitals in Denpasar. Subjects were children aged 6 to 59 months with acute rotavirus diarrhea. Rotavirus was diagnosed by immune chromatography assay. The synbiotic group received probiotic comprised of Lactobacillus sp., Streptococcus sp., Bifidobacterium sp. (total viable count 1.00x109 CFU per dose, and prebiotic consisted of 990.00 mg fructooligosacharide (FOS. The placebo consisted of lactose monohydrate packaged similarly as the synbiotics. Subjects orally ingested 1 pack per day for 5 days. Results Seventy children with acute rotavirus diarrhea was involved in this study. The median duration of diarrhea in the synbiotic group was 50.0 (SE 1.1; 95%CI 47.9 to 52.1 hours, while that of the placebo group was 63.0 (SE 5.9; 95%CI 51.4 to 74.6 hours. Based on Kaplan-Meier survival analysis, the duration of diarrhea in the synbiotic group was significantly shorter than that of the placebo group (log-rank test P <0.0001. Conclusion In children with acute rotaviral diarrhea, synbiotic reduces the duration of diarrhea compared to placebo. [Paediatr Indones. 2015;55:74-8.].

    Full Text Available Kevin W OldenDepartment of Medicine, St Joseph's Hospital and Medical Center, Phoenix, AZ, USAAbstract: Irritable bowel syndrome (IBS causes gastrointestinal symptoms such as abdominal pain, bloating, and bowel pattern abnormalities, which compromise patients' daily functioning. Common therapies address one or two IBS symptoms, while others offer wider symptom control, presumably by targeting pathophysiologic mechanisms of IBS. The aim of this targeted literature review was to capture clinical trial reports of agents receiving the highest recommendation (Grade 1 for treatment of IBS from the 2009 American College of Gastroenterology IBS Task Force, with an emphasis on diarrhea-predominant IBS. Literature searches in PubMed captured articles detailing randomized placebo-controlled trials in IBS/diarrhea-predominant IBS for agents receiving Grade I (strong 2009 American College of Gastroenterology IBS Task Force recommendations: tricyclic antidepressants, nonabsorbable antibiotics, and the 5-HT3 receptor antagonist alosetron. Studies specific for constipation-predominant IBS were excluded. Tricyclic antidepressants appear to improve global IBS symptoms but have variable effects on abdominal pain and uncertain tolerability; effects on stool consistency, frequency, and urgency were not adequately assessed. Nonabsorbable antibiotics show positive effects on global symptoms, abdominal pain, bloating, and stool consistency but may be most efficacious in patients with altered intestinal microbiota. Alosetron improves global symptoms and abdominal pain and normalizes bowel irregularities, including stool frequency, consistency, and fecal urgency. Both the nonabsorbable antibiotic rifaximin and the 5-HT3 receptor antagonist alosetron improve quality of life. Targeted therapies provide more complete relief of IBS symptoms than conventional agents. Familiarization with the quantity and quality of evidence of effectiveness can facilitate more individualized

    2014-06-01

    Viral gastroenteritis is a common public health problem that causes morbidity and mortality worldwide. Recently, new viruses causing gastroenteritis have been identified. Among these, Aichivirus has also been proposed as a causative agent of gastroenteritis in human. Most studies have been conducted in infants and children, the information in adults is limited. Therefore, the purpose of this study was to investigate the epidemiology and molecular characterization of Aichivirus in adult patients with diarrhea. A total of 332 fecal specimens collected from January to December 2008 were screened for the presence of Aichivirus by reverse transcription-PCR (RT-PCR) method. Out of 332 fecal specimens tested, Aichivirus was detected with the prevalence of 0.9% (3/332). The data indicate that the prevalence of Aichivirus in adults was as low as those reported in children in Thailand. Phylogenetic analysis of the VP1 sequence revealed that one Aichivirus belonged to genotype A, while other two Aichiviruses were genotype B. In conclusion, this study provided the molecular epidemiological data of Aichivirus circulating in adult patients with diarrhea at low prevalence and the viruses were genetically variable as both genotypes A and B were found in this population.

  16. Pathological studies on bovine viral diarrhea

    Bovine viral diarrhea virus (BVDV) is classified as an RNA virus in the family flavin viride and is a member of the genus pest virus (Collet et al 1989). BVDV has a worldwide distribution and infections in cattle populations (Kahrs et al 1970). It was recognized since 50 years ago, the initial description of an acute enteric disease of cattle in North America, which was characterized by outbreaks of diarrhea and erosive of digestive tract (Olafsonp et al 1946). The disease and causative agent were named bovine viral diarrhea (B V D ) and (B V DV), respectively. This virus was subsequently associated with a sporadically occurring and highly fatal enteric disease that was termed mucosal disease (M D), (Ramsey and Chivers 1953). The initial isolate of BVDV did not produce cytopathic effect in cell culture, whereas an isolate from MD did produce cytopathic effects (Lee et al 1957). In vitro characteristic of non cytopathic or sytopathic effects of BVDV is referred to as the biotype of the virus. It has now been established that MD occurs only when xattle that are born immuno tolerant to and persistently infected with a noncyropathic BVDV become super infected with a cytopathic BVDV. The knowledge of the molecular biology. Pathogenesis and epidemiology of BVDV has greatly evolved in the past 10-15 years and has provided a better understanding of this complex infectious agent. Infection with BVDV can result in a wide spectrum of diseases ranging from subclinical infection s to a highly fatal from known as mucosal disease (ND). The clinical response to infection depends on multiple interactive factors. Host factors that influence the clinical outcome of BVDV infection include whether the host is immunocompetent or immuno tolerant to BVDV, pregnancy status, gestational age of the fetus, immune status (passively derived or actively derived from previous infection or vaccination) and concurrent level of environmental stress

    2016-01-01

    Background: Acute diarrhea remains the serious problem in developing countries, especially among children under 5 years of age. Currently, only two or three common diarrhea pathogens were screened at most hospitals in China. The aim of this study was to provide a wide variety of diarrhea pathogens and their antimicrobial resistance patterns in children under 5 years of age. Methods: Totally 381 stool samples collected from Tongji Hospital between July 1, 2014 and June 30, 2015 were tested by culture and/or polymerase chain reaction for eight kinds of bacteria and five kinds of viruses. An antimicrobial sensitivity test was performed using dilution method recommended by the Clinical and Laboratory Standards Institute. Results: Viral infections were mainly identified in infants (0–11 months), whereas bacterial infections were more prevalent in the age of 24–59 months. About 69.8% of samples were positive for at least one pathogen, 51.7% of samples were virus positive, followed by bacteria positive cases (19.4%), and 12.6% of cases displayed co-infections with two viruses or a virus and a bacterium. Rotavirus was the most prevalent pathogen, followed closely by norovirus, while Salmonella was the most commonly isolated bacteria, followed by diarrheagenic Escherichia coli (DEC) and Campylobacter. More than 40% of Salmonella spp. and DEC isolates were resistant to first-line antibiotics (ampicillin, trimethoprim-sulfamethoxazole, and tetracycline). Around 10% of Salmonella spp. isolates were resistant to ceftriaxone and ciprofloxacin simultaneously. Campylobacter spp. displayed high resistance to ciprofloxacin but kept low resistance to azithromycin and doxycycline. Conclusions: The etiology of acute diarrhea varies in children of different age groups. The high frequency of infection with viruses suggests the urgent demand for new viral vaccine development. Proper use of antibiotics in the treatment of acute diarrhea is crucial due to the high level of antibiotic

    In spite of continued efforts, India is still lagging behind in achieving its MDG goals. The objectives of this study were to identify stake-holders who have a role to play in childhood diarrhea management, to identify gaps in childhood diarrhea management and to propose strategic options for relieving these gaps. Bottleneck analysis exercise was carried out based on the Tanahashi model in six High Priority Districts (HPDs) of Gujarat in period between July-November 2013. The major bottlenecks identified for Childhood Diarrhea management were poor demand generation, unsafe drinking water, poor access to improved sanitation facility and lack of equitable distribution and replenishment mechanisms for Oral Rehydration Solution (ORS) packets and Zinc tablets till the front-line worker level. The main strategic options that were suggested for relieving these bottlenecks were Zinc-ORS roll out in scale-up districts, develop Information Education Communication/Behaviour Change Communication (IEC/BCC) plan for childhood diarrhea management at state/district level, use of Drug Logistics Information Management System (DLIMS) software for supply chain management of Zinc-ORS, strengthening of chlorination activity at household level, monitoring implementation of Nirmal Bharat Abhiyaan (NBA) for constructing improved sanitation facilities at household level and to develop an IEC/BCC plan for hygiene promotion and usage of sanitary latrines. Use of Zinc tablets need to be intensified through an effective scale-up. Adequate demand generation activity is needed. There is need to address safe drinking water and improved sanitation measures at household levels. Multi-sectoral engagements and ownership of Zinc-ORS program is the need of the hour. PMID:27340871

  6. Acute Diarrhea; Admitted Children; Clinical Trial; Zinc Supplementation

    2013-01-01

    Full Text Available Introduction: Acute diarrhea remains a major cause of morbidity and mortality among infants and young children as well as an important determinant of growth faltering in the world. Significant proportions of children who suffer from diarrhea are malnourished with depleted micronutrient stores. Diarrhea also leads to excess loss of micronutrients such as zinc and copper. Methods: This study was a clinical trial. The samples were collected from the children admitted. The children were randomly assigned to zinc and control groups among which zinc group received 2 mg/kg of zinc supplementation daily. A questionnaire was utilized as the research instrument containing the demographic information as well as number of stools and duration of admission. Results: After starting supplementation, the mean duration of diarrhea was 3.7±0.95 days in the zinc group and 4.6±1.8 days in the control group, showing a significant difference (P0.05 except on the sixth day. Conclusion: Zinc supplementation reduces the duration of acute diarrhea in admitted 1-60 month old children but has no effects on severity of acute diarrhea except on the sixth day of diarrhea duration.

    Evacuation of residents and diarrhea disease outbreak in evacuation zone have become serious problem that frequently happened during flood periods. Limited clean water supply and infrastructure in evacuation zone contribute to a critical spread of diarrhea. Transmission of diarrhea disease can be reduced by controlling clean water supply and treating diarrhea patients properly. These treatments require significant amount of budget, which may not be fulfilled in the fields. In his paper, transmission of diarrhea disease in evacuation zone using SIRS model is presented as control optimum problem with clean water supply and rate of treated patients as input controls. Existence and stability of equilibrium points and sensitivity analysis are investigated analytically for constant input controls. Optimum clean water supply and rate of treatment are found using optimum control technique. Optimal results for transmission of diarrhea and the corresponding controls during the period of observation are simulated numerically. The optimum result shows that transmission of diarrhea disease can be controlled with proper combination of water supply and rate of treatment within allowable budget.

    AIM: During emergency period, infectious diseases can bea major threat to military forces. During field training insouthern China, diarrhea is the main cause of nonbattleinjury. To evaluate the causes of and risk factors for diarrheain emergency period, we collected clinical and epidemiologicaldata from the People′s Liberation Army (PLA) during fieldtraining in southern China.METHODS: From September 25 to October 2 1997, 2636military personnel were investigated. Fecal sample cultures for lapactic pathogens were obtained from 103 military personnel with diarrhea. In addition, a questionnaire was administered to 103 cases and 206 controls to evaluate the association between illness and potential risk factors. At the same time,another questionnaire of 1:4 case-case control was administered to 22 severe cases (each severe case paired 4 mild cases).RESULTS: The training troop′s diarrhea incidence rate was significantly higher than that of garrison. The diarrhea incidence rate of officers was significantly lower than that of soldiers. A lapactic pathogen was identified in 63.1% (65/103) of the troops with diarrhea. Enterotoxigenic Escherichia coli(35.0%) and plesiomona shigelloides (16.5%) were the most common bacterial pathogens. All bacterial isolates were sensitive to norfloxacin and ceftazidine. However, almost all of them were resistant to sulfamethoxazole, trimethoprim-sulfamethoxazole,oxytetracycline, doxycycline, furazolidone, ampicillin and cloromycetin to a different degree. Risk factors associated with diarrhea includediidrinking raw water, eating outside,contacting diarrhea patients, lacking sanitation, depression,lacking sleep, which were established by multiple-factor logistic regression analysis. In addition, the unit incidence rate was associated with the density of flies and the average daily boiled water available by regression and discriminate analysis.CONCLUSION: A series of risk factors are associated with the incidence rate of diarrhea.

    2016-03-01

    Bovine viral diarrhea (BVD) affects bovine production and reproduction causing significant economic losses all over the world. Two viral species has been recognized: BVDV-1 and BVDV-2, both distributed worldwide. Recently, novel specie of BVDV named HoBi-like pestivirus was discovered. The presence of BVDV was confirmed in 1996 in Uruguay, however, does not exist until today a schedule of compulsory vaccination along the country. Serological studies with samples from all Uruguayan herds were performed during 2000 and 2001 demonstrating that all of them were seropositive to BVDV with a mean prevalence of 69%. In addition, there have been no new studies done since those previously described and it is important to mention that the genetic diversity of BVD has never been described in Uruguay. Nowadays, there is strongly suspect that BVDV is one of the most important causes of reproductive failures in our herds. The aim of this study was to describe for the first time in Uruguay the genetic diversity of BVDV with samples collected from different regions along the country. Serological status of 390 non-vaccinated animals against BVDV with reproductive problems from farms of Rivera, Tacuarembó and Florida departments of Uruguay were studied. All herds were seropositive to BVDV and high proportion of animals were positive (298/390), while 4.1% (16/390) of the animals were positive to Antigen Capture ELISA test and Real Time PCR. Phylogenetic analysis performed with concatenated sequences from the 5'UTR and Npro genomic regions revealed that BVDV-1 and BVDV-2 are infecting our herds, being BVDV-1 the most frequently found. The major subtype was BVDV-1a, followed by BVDV-1i and BVDV-2b. This is the first study that describes the genetic diversity of BVDV in Uruguay and it will contribute to the elaboration of sanitization programs. PMID:26597189

    2009-01-01

    Objective:Diarrhea is a leading cause of morbidity and mortality among children in developing countries.The bacterial pathogen most commonly associated with childhood diarrhea is Escherichia coli.A one-year prospec-tive study was carried out in Sanandaj to determine the prevalence and roles of the different E.coli pathotypes in children less than five years of age with acute diarrhea.Methods:Rectal swab were collected prospectively from children with acute diarrhea and transported to the Department of Microbiology,School of Medicine, KUMS,Sanandaj during 2008.The study was approved by the institutional ethics committee.Results:During this study period,rectal swabs were investigated from a total of 466 children 1 to 144 months of age (mean, 29.97 months ±S.D)with diarrhea.Among the children,191 (41%,191 /466)were girls,and 275 (59%,275 /466)were boys.The age-specific incidence rates of acute diarrhea among children 13 -24 and 1-12 months of age were 37.37% (37 /99)and 26.26 % (26 /99),respectively,during the study period.A total of 99 strains of E.coli were detected.EPEC 59 (59.59%)and EIEC 22 (22.22%),were the most commonly found Escherichia coli strains detected in stools from children.Disk diffusion testing showed E.coli strains resistance to tetracycline (89.89 %),chloramphenicol (88.88%),Ampicillin (79.79%),Amoxi-cillin (75.75%)and Ceficime (75.75%).Among risk factors like age,sex,haemoglubin,father's and moth-er's education,food and weight of children only mother's education was significant (P =0.018).Conclusion:In most of the clinical laboratories in Iran,E.coli does not considered as an etiologic agent responsible for di-arrhea.Results in this study revealed that E.coli should be considered as an etiologic agent causing acute di-arrhea among children.We therefore,recommend the routine isolation and identification of E.coli strains in all the clinical laboratories in Sanandaj.Guidelines for appropriate use of antibiotics in Sanandaj need upda-ting.

  14. Control of radiation-induced diarrhea with cholestyramine

    Cholestyramine is a non-absorbable ion-exchange resin which specifically binds bile salts. We have treated seven patients with acute or chronic radiation-induced diarrhea that was refractory to the usual methods of control with cholestyramine. In each case, the diarrhea was controlled with cholestyramine. This observation supports previous experimental work with animals which indicated that bile salts contribute to the genesis of radiation-induced diarrhea. Cholestyramine is well-tolerated, but should not be administered with certain oral medications. The results of this small series are preliminary, but point the way toward a more extensive clinical trial to define the usefulness of cholestyramine in the treatment of refractory acute or chronic radiation-induced diarrhea

  15. Persistent diarrhea as an emerging child health problem

    Galal Osman

    1997-01-01

    Full Text Available Persistent diarrhea (i.e. acute episodes lasting more than 14 days has been recognized by the WHO as a major public health problem in developing countries and a research topic of high priority. Persistent diarrhea is often associated with malnutrition, growth faltering, and a substantial risk of mortality in children below 5 years of age. Reported incidence and case-fatality rates from persistent diarrhea vary substantially. Substantial disagreement exists regarding definition, incidence and various putative risk factors. Resolution of such measurement related problems will allow for an accurate estimate of the force of morbidity and mortality from presistent diarrhea, while the elucidation of its risk factors will simplify policy making and the tailoring of intervention programs.

  2. [Diagnostic workup and therapy of infectious diarrhea. Current standards].

    Stallmach, A; Hagel, S; Lohse, A W

    2015-12-01

    Infectious diarrhea is very common; its severity ranges from uncomplicated, self-limiting courses to potentially life-threatening disease. A rapid diagnostic workup providing detailed information on the suspected pathogen should be performed only in patients at risk, analyzing one single stool sample for Salmonella, Shigella, Campylobacter, and Norovirus. In the presence of risk factors, such as a history of antibiotic exposure within the last 3 months, testing for Clostridium difficile should be performed. Immunocompetent patients do not require specific antibiotic therapy. Exceptions exist in patients with severe comorbidities, immunodeficiency, fever/SIRS, and in patients with Shigella or C. difficile infection. Empirical antibiotic treatment should be considered in patients with fever and/or bloody diarrhea and in patients at risk. In patients with traveler's diarrhea, microbiological diagnosis is required only in patients with fever, bloody diarrhea, prolonged course of disease (more than 5 days), severe clinical course with hypotension or dehydration, and during outbreaks. In these patients one single fecal sample should be collected for stool cultures of Campylobacter, Shigella, and Salmonella, as well as microscopic examination for amoebiasis and Giardiasis. The main therapeutic measure for infectious diarrhea is sufficient oral rehydration. As in community-acquired diarrhea, azithromycin or ciprofloxacin are recommended-taking into account local antimicrobial resistance in the country of travel and possible side effects. PMID:26573083

  3. [Acute infectious diarrhea in adults: epidemiology and management].

    Beaugerie, Laurent; Sokol, Harry

    2013-01-01

    Acute diarrhea is defined as an abnormally frequent discharge of semisolid or fluid fecal matter from the bowel, lasting less than 14 days. More than three millions cases of acute diarrhea, presumably due to intestinal infections, are seen in general practice every year in France. Most of the cases are benign and resolve under symptomatic treatment within 3 days, without need for biological tests or antibiotics. In special contexts (septicemic syndrome, visible blood in stools, severe dehydration, patients at risk of severe sepsis [valvulopathy]), biologic tests and probabilist antibiotic treatment are required. Hygiene, rehydration and diet recommendations are always part of the treatment of acute diarrhea, in addition to the symptomatic treatment of diarrhea and other digestive symptoms. Antibiotic-associated diarrhea is clinically benign in most cases, and attributed to transient dysbiosis of gut microbiota. In the remaining cases, diarrhea is the clinical expression of intestinal infection by Clostridium difficile, that should be treated with metronidazole, or the clinical expression of a Klebsiella oxytoca-associated colitis that usually spontaneously resolves after stopping antibiotics.

  4. An external evaluation of the Diarrhea Alleviation through Zinc and ORS Treatment (DAZT program in Gujarat and Uttar Pradesh, India

    Laura M Lamberti

    2015-12-01

    Full Text Available To address inadequate coverage of oral rehydration salts (ORS and zinc supplements for the treatment of diarrhea among children under–five, the Diarrhea Alleviation through Zinc and ORS Treatment (DAZT program was carried out from 2011–2013 in Gujarat and from 2011–2014 in Uttar Pradesh (UP, India. The program focused on improving the diarrhea treatment practices of public and private sector providers. We conducted cross–sectional household surveys in program districts at baseline and endline and constructed state–specific logistic regression models with generalized estimating equations to assess changes in ORS and zinc treatment during the program period. Between baseline and endline, zinc coverage increased from 2.5% to 22.4% in Gujarat and from 3.1% to 7.0% in UP; ORS coverage increased from 15.3% to 39.6% in Gujarat but did not change in UP. In comparison to baseline, children with diarrhea in the two–weeks preceding the endline survey had higher odds of receiving zinc treatment in both Gujarat (odds ratio, OR = 11.2; 95% confidence interval (CI 6.4–19.3 and UP (OR = 2.4; 95% CI 1.4–3.9, but the odds of receiving ORS only increased in Gujarat (OR = 3.6; 95% CI 2.7–4.8; UP OR = 0.9; 95% CI 0.7–1.2. Seeking care outside the home, especially from a public sector source, was associated with higher odds of receiving ORS and zinc. Conclusions During the duration of the DAZT program, there were modest improvements in the treatment of diarrhea among young children. Future programs should build upon and accelerate this trend with continued investment in public and private sector provider training and supply chain sustainability, in addition to targeted care–giver demand generation activities.

    Full Text Available Abstract Background Adjuvant therapy to ORT with probiotic bacteria for infants with acute watery diarrhea has been under active investigation. Most studies have been done in the developed world showing benefit only for viral mild gastroenteritis. We evaluated the effect of a milk formula containing one billion (109 cfu/ml of Lactobacillus casei strain GG (LGG upon duration and severity of diarrhea in infants in an environment with more severe acute diarrhea, where etiologic agents other than rotavirus are involved more frequently, and where mixed infections are more prevalent. Methods Male infants aged 3–36 months brought for treatment of acute watery diarrhea of less than 48 hours were eligible. After rehydration was completed with the WHO's oral rehydration solution, patients were randomly assigned to receive a milk formula either containing LGG or not. Stool volume was periodically measured using a devise suited to collect stools separate from urine. Duration of diarrhea was estimated based on stools physical characteristics. Results Eighty nine patients received the placebo milk formula and ninety received the LGG containing formula. Both groups were comparable in their baseline characteristics. Total stool output was significantly larger (p = 0.047 in the LGG group (247.8 ml/kg than in the placebo group (195.0 ml/kg. No significant differences were found in duration of diarrhea (58.5 hours with LGG vs. 50.4 hours with placebo, rate of treatment failure (21.1% with LGG vs. 18.0% with placebo, and proportion of patients with unresolved diarrhea after 120 hours (12.2% with LGG vs. 12.5% with placebo. The rate of stools with reducing substances after 24 hours of treatment increased significantly in both groups (from 41.4% to 72.2% with LGG and from 45.9% to 68.0% with placebo. Conclusion This study did not show a positive effect of LGG on the clinical course of acute watery diarrhea. Positive beneficial effects of LGG, as had been reported

    Patel, Archana

    2015-08-01

    Acute diarrhea and pneumonia are the two largest killers of under-five children in the world. Zinc, used in management of acute diarrhea and Amoxicillin, used in community acquired pneumonia, feature in the list of 13 Life Saving Commodities for Women's and Children Health by the UN Commission. Zinc has caught wide scientific attention for the conceptual promise it has to offer for prevention, control and treatment of acute diarrhea. This presentation focuses on author's research on the mechanisms by which zinc might contribute to the pathogenesis of acute diarrhea and the degree of success achieved in diarrhea control and treatment by zinc supplementation including its impact on mortality. However, emerging evidence in terms of controlled studies in humans beckons a more complete understanding of the mechanistic basis for zinc supplementation. Current evidence indicates that studies specifically addressing the variability in response to zinc supplementation need to be undertaken to better comprehend these mechanisms. Similarly, the author presented her research that examined the role of oral amoxicillin in community management of severe pneumonia in children and the need to assess its universal efficacy in all children with severe pneumonia.

  7. Addressivity in cogenerative dialogues

    Hsu, Pei-Ling

    2014-03-01

    Ashraf Shady's paper provides a first-hand reflection on how a foreign teacher used cogens as culturally adaptive pedagogy to address cultural misalignments with students. In this paper, Shady drew on several cogen sessions to showcase his journey of using different forms of cogens with his students. To improve the quality of cogens, one strategy he used was to adjust the number of participants in cogens. As a result, some cogens worked and others did not. During the course of reading his paper, I was impressed by his creative and flexible use of cogens and at the same time was intrigued by the question of why some cogens work and not others. In searching for an answer, I found that Mikhail Bakhtin's dialogism, especially the concept of addressivity, provides a comprehensive framework to address this question. In this commentary, I reanalyze the cogen episodes described in Shady's paper in the light of dialogism. My analysis suggests that addressivity plays an important role in mediating the success of cogens. Cogens with high addressivity function as internally persuasive discourse that allows diverse consciousnesses to coexist and so likely affords productive dialogues. The implications of addressivity in teaching and learning are further discussed.

    The incidence of bacterial diarrhea in AIDS patients has increased steadily and has led to enormous medical and public health problems. In this study, the clinical data together with 350 rectal swab samples each from AIDS patients with diarrhea (APD) and non-AIDS patients with diarrhea (NAPD), were collected and examined for bacterial enteropathogens at the Bamrasnaradura Infectious Diseases Hospital (BIDH), Nonthaburi, Thailand from May to December 1996. Patients were matched by age and sex. The majority of these patients were male (79%, 554/700), aged between 15 and 34 years (70.9%). The study found that the isolation rates of bacterial enteropathogens causing diarrhea in APD (18%, 62/350) were considerably lower than those in NAPD (43%, 152/350) (pvtl and vt2. No V. cholerae strains were detected in APD. The least effective antibiotics were ampicillin, tetracycline and cotrimoxazole. Antibiotic resistant patterns of the isolated organisms were similar from both groups. The results from this study might be useful in Thailand in the diagnosis and management of clinical cases of bacterial diarrhea, especially APD. PMID:11485080

    The aim of this study is to report a case of Clostridium difficile-associated diarrhea in an ocelot (Leopardus pardalis) in the state of Mato Grosso do Sul, Brazil. The animal, a 24-month-old male, was referred to the Centro de Reabilitação de Animais Silvestres (CRAS) with a history of having been run over and tibia and fibula fractures. After a surgery to repair the fractures, the ocelot underwent antibiotic therapy with two doses of sodium cefovecin, during which he presented with diarrhea. A stool sample was positive for A/B toxins by a cytotoxicity assay, and a toxigenic strain of C. difficile was isolated. No other enteropathogens were detected. The association between the history, clinical signs and laboratory exams confirmed the diagnosis of C. difficile-associated diarrhea. The present report confirms C. difficile as a potential pathogen for wild felids and suggests that the C. difficile-associated diarrhea should be considered in diarrhea cases, especially when the clinical signs began after antimicrobial use.

Objective: To spotlight the common presentation of CCD for early management and prevention of complications. Subjects and methods: This is a retrospective case series study of patients diagnosed as CCD who were followed up in the pediatric department of Al-Adan Hospital, Kuwait. Results: Twelve patients diagnosed with CCD were born to consanguineous parents; had antenatal history of intrauterine growth retardation (IUGR; polyhydramnios; and distended hypoechoic fetal bowel; and presented with abdominal distension, hypotonia and muscle wasting. 90% of patients had maternal hypertension and 75% of patients had absence of normal meconium at birth. Our patients showed a decrease in serum sodium, potassium, chloride and urine chloride. Conclusion: A high level of suspicion for an early diagnosis of CCD should be considered for any infant presenting with chronic diarrhea, especially in the presence of consanguineous marriage, and the characteristic features in antenatal ultrasound. Thus, allowing for early investigations and appropriate management. Keywords: congenital chloride diarrhea, children, chronic diarrhea, metabolic alkalosis, prenatal diagnosis

    AIM: To investigate the efficacy of a high-potency probiotic preparation on prevention of radiation-induced diarrhea in cancer patients.METHODS: This was a double-blind, placebo-controlled trial. Four hundred and ninety patients who underwent adjuvant postoperative radiation therapy after surgery for sigmoid, rectal, or cervical cancer were assigned to either the high-potency probiotic preparation VSL#3 (one sachet t.i.d.,) or placebo starting from the first day of radiation therapy. Efficacy endpoints were incidence and severity of radiation-induced diarrhea, daily number of bowel movements, and the time from the start of the study to the use of loperamide as rescue medication.RESULTS: More placebo patients had radiation-induced diarrhea than VSL#3 patients (124 of 239 patients, 51.8%, and 77 of 243 patients, 31.6%; P < 0.001) and more patients given placebo suffered grade 3 or 4 diarrhea compared with VSL#3 recipients (55.4% and 1.4%, P < 0.001). Daily bowel movements were 14.7 ± 6 and 5.1 ± 3 among placebo and VSL#3 recipients (P < 0.05), and the mean time to the use of loperamide was 86 ± 6 h for placebo patients and 122 ± 8 h for VSL#3 patients (P < 0.001).CONCLUSION: Probiotic lactic acid-producing bacteria are an easy, safe, and feasible approach to protect cancer patients against the risk of radiation-induced diarrhea.

    Full Text Available Abstract Background Zinc deficiency is commonly prevalent in children in developing countries and plays a role in decreased immunity and increased risk of infection. Preventive zinc supplementation in healthy children can reduce mortality due to common causes like diarrhea, pneumonia and malaria. The main objective was to determine all-cause mortality and cause-specific mortality and morbidity in children under five in developing countries for preventive zinc supplementation. Data sources/ review methods A literature search was carried out on PubMed, the Cochrane Library and the WHO regional databases to identify RCTs on zinc supplementation for greater than 3 months in children less than 5 years of age in developing countries and its effect on mortality was analyzed. Results The effect of preventive zinc supplementation on mortality was given in eight trials, while cause specific mortality data was given in five of these eight trials. Zinc supplementation alone was associated with a statistically insignificant 9% (RR = 0.91; 95% CI: 0.82, 1.01 reduction in all cause mortality in the intervention group as compared to controls using a random effect model. The impact on diarrhea-specific mortality of zinc alone was a non-significant 18% reduction (RR = 0.82; 95% CI: 0.64, 1.05 and 15% for pneumonia-specific mortality (RR = 0.85; 95% CI: 0.65, 1.11. The incidence of diarrhea showed a 13% reduction with preventive zinc supplementation (RR = 0.87; 95% CI: 0.81, 0.94 and a 19% reduction in pneumonia morbidity (RR = 0.81; 95% CI: 0.73, 0.90. Keeping in mind the direction of effect of zinc supplementation in reducing diarrhea and pneumonia related morbidity and mortality; we considered all the outcomes for selection of effectiveness estimate for inclusion in the LiST model. After application of the CHERG rules with consideration to quality of evidence and rule # 6, we used the most conservative estimates as a surrogate for mortality. We, therefore

  14. Clostridium difficile associated infection, diarrhea and colitis

    Perry Hookman; Jamie S Barkin

    2009-01-01

    A new, hypervirulent strain of Clostridium difficile, called NAP1/BI/027, has been implicated in C. difficile outbreaks associated with increased morbidity and mortality since the early 2000s. The epidemic strain is resistant to fluoroquinolones in vitro, which was infrequent prior to 2001. The name of this strain reflects its characteristics, demonstrated by different typing methods: pulsed-field gel electrophoresis (NAP1), restriction endonuclease analysis (BI) and polymerase chain reaction (027). In 2004 and 2005, the US Centers for Disease Control and Prevention (CDC) emphasized that the risk of C. difficile-associated diarrhea (CDAD) is increased, not only by the usual factors, including antibiotic exposure, but also gastrointestinal surgery/manipulation, prolonged length of stay in a healthcare setting, serious underlying illness, immune-compromising conditions, and aging. Patients on proton pump inhibitors (PPIs) have an elevated risk, as do peripartum women and heart transplant recipients. Before 2002, toxic megacolon in C. difficile-associated colitis (CDAC), was rare, but its incidence has increased dramatically. Up to twothirds of hospitalized patients may be infected with C. difficile. Asymptomatic carriers admitted to healthcare facilities can transmit the organism to other susceptible patients, thereby becoming vectors. Fulminant colitis is reported more frequently during outbreaks of C. difficile infection in patients with inflammatory bowel disease (IBD). C. difficile infection with IBD carries a higher mortality than without underlying IBD. This article reviews the latest information on C. difficile infection, including presentation, vulnerable hosts and choice of antibiotics, alternative therapies, and probiotics and immunotherapy. We review contact precautions for patients with known or suspected C. difficileassociated disease. Healthcare institutions require accurate and rapid diagnosis for early detection of possible outbreaks, to initiate

    Bovine viral diarrhea virus causes a wide range of clinical manifestation with subsequent economic losses in dairy production worldwide. Our study of a population of dairy cattle in Thailand based on 933 bulk tank milk samples from nine public milk collection centers aimed to monitor infective status and to evaluate the effect of the infection in cows as well as to examine the reproductive performance of heifers to provide effective recommendations for disease control in Thailand. The results showed a moderate antibody-positive prevalence in the herd (62.5 %), with the proportion of class-3 herd, actively infected stage, being 17.3 %. Fourteen persistently infected (PI) animals were identified among 1196 young animals from the class-3 herds. Most of the identified PI animals, 11/14, were born in one sub-area where bovine viral diarrhea virus (BVDV) investigation has not been performed to date. With respect to reproductive performance, class-3 herds also showed higher median values of reproductive indices than those of class-0 herds. Cows and heifers in class-3 herds had higher odds ratio of calving interval (CI) and age at first service (AFS) above the median, respectively, compared to class-0 herds (OR = 1.29; P = 0.02 and OR = 1.63; P = 0.02). Our study showed that PI animals were still in the area that was previously studied. Furthermore, a newly studied area had a high prevalence of BVDV infection and the infection affected the reproductive performance of cows and heifers. Although 37.5 % of the population was free of BVDV, the lack of official disease prevention and less awareness of herd biosecurity may have resulted in continuing viral spread and silent economic losses have potentially occurred due to BVDV. We found that BVDV is still circulating in the region and, hence, a national control program is required. PMID:27154218

    Hosseini Nave, Hossein; Mansouri, Shahla; Sadeghi, Amin; Moradi, Mohammad

    2016-01-01

    Aim: This study aims to determine the serogroup distribution and molecular diagnosis, as well as antimicrobial resistance profiles among Shigella spp. isolated from patients with diarrhea in Kerman, southeast of Iran. Background: Shigella species are frequent cause of bacterial dysentery worldwide. Previous studies have been reported that S. sonnei and S. flexneri are the most prevalent serogroups in various parts of Iran. Patients and methods: A total of 624 stool samples were randomly collected from patients with diarrhea from June 2013 to August 2014. Biochemical and serological characterizations were performed for identifying Shigella spp. In addition, the multiplex PCR assay was carried out for the detection and differentiation of three pathogenic Shigella spp. Antibiotic susceptibility testing was performed according to the Clinical Laboratory Standards Institute (CLSI) guidelines. Results: Fifty six (9%) Shigella strains were isolated from stool samples. The most common species were S. flexneri 31(55.4%), followed by S .sonnei 18(32.1%) and S. boydii 7(12.5%). S. dysentery was not detected in the present study. All the isolates that identified by serological test as Shigella spp. were confirmed by the multiplex PCR method. The highest rate of resistance was observed for ampicillin and trimethoprim-sulphamethoxazole antibiotics with 52(92.9%) resistant, followed by tetracycline 44(78.6%) and cefotaxime 33(58.9%). All Shigella isolates were susceptible to ciprofloxacin. A significant relationship was found between the Shigella species and cefotaxime resistance (p<0.05). Conclusion: S. flexneri was found as the most prevalent serogroup causing shigellosis. The high rate of resistance to third-generation cephalosporins limits the treatment options available for the management of shigellosis in Kerman, Iran.

    The aim of this study was to investigate the frequency of intestinal parasites in patients with chronic diarrhea and clarify the importance of these parasitic pathogens in such cases. A total of 60 pediatric patients with chronic diarrhea between June 2012 and October 2014 were enrolled in the study. Out of 60 stool samples, five were positive for Giardia lamblia, two, Dientamoeba fragilis, and one, Blastocystis hominis. One stool sample was positive for Entamoeba hartmanni and B. hominis, another one was positive for G. lamblia and B. hominis, another, G. lamblia and E. hartmanni and one sample was positive for Enterobius vermicularis, D. fragilis and B. hominis together. Parasitic infection, which decreases quality of life and increases susceptibility to other infections, should not be neglected, particularly in patients with chronic diarrhea. Accurate diagnosis decreases morbidity and mortality in patients with parasite infection. PMID:27322863

  18. Intestinal secretory mechanisms in irritable bowel syndrome-diarrhea.

    Camilleri, Michael

    2015-06-01

    Although diarrhea is the predominant bowel dysfunction in as many as one-third of patients with irritable bowel syndrome (IBS), it is unclear whether there is a specific disorder of intestinal fluid or electrolyte secretion in IBS. Diarrhea is generally considered a result of accelerated colonic transit in patients with IBS. Although a primary secretory diathesis has not been well-documented in patients with IBS with diarrhea (IBS-D), several mechanisms that could potentially contribute to intestinal secretion have been reported. Some of these mechanisms also influence motor and secretory dysfunctions that contribute to the pathophysiology of IBS-D. We review the evidence supporting secretion in IBS-D caused by peptides and amines produced by enteroendocrine cells or submucosal neurons, enterocyte secretory processes, and intraluminal factors (bile acids and short-chain fatty acids). Understanding these mechanisms and developing clinical methods for their identification could improve management of patients with IBS-D. PMID:25041862

  19. Colestipol hydrochloride prophylaxis of diarrhea during pelvic radiotherapy

    Thirty-three patients were randomized prior to pelvic radiotherapy to receive the bile acid-sequestering resin colestipol hydrochloride, 5 grams qid, during the entire time of their therapy or diphenoxylate hydrochloride and atropine sulfate 2.5-20 mg per day (control) if they experienced diarrhea. The colestipol patients also took diphenoxylate if they had diarrhea. The patients in the colestipol group often experienced nausea, vomiting, and abdominal cramps and 8 were forced to discontinue the drug. There was no difference in the weekly stool frequency between the colestipol and the control patients but the colestipol patients who took at least 50% of the prescribed dose required fewer diphenoxylate tablets than the controls. The data suggest that colestipol hydrochloride is not of value in preventing radiation-induced diarrhea because of the side effects associated with the drug, but the theory on which the use of bile acid-sequestering agents is based may be correct

  20. Addressing the nuclear misconception

    There is a perception, fostered and encouraged by the anti-nuclear groups, that the nuclear industry generates large quantities of waste with no idea how to deal with it, that it is unsafe, uneconomic, and environmentally damaging. The task is to change these perceptions, by demonstrating that the industry is not a problem in itself, but in fact provides solutions to problems. This paper, while primarily concerned with waste, addresses all of these issues as each has a bearing on the perception of the industry and therefore must be considered when addressing the issue of waste. The paper concludes that evidence exists to support the industry view, but that the mission of the industry should be to change the perception of the industry, by influencing and working together with its stake holders to address their concerns, rather than merely presenting more and more facts.

    2016-10-01

    Acute diarrhea disease caused by Rotaviruses A (RVA) is still the leading cause of morbidity and mortality in children ≤5 years old in developing countries. An exploratory cross-sectional study was conducted between February and September, 2011 to determine the proportion of acute diarrhea caused by RVA. A total of 254 stool specimens were collected from children ≤5 years old with acute diarrhea, including outpatients (222 children) and inpatients (32 children), in three local health centers in Chókwè District, Gaza Province, South of Mozambique. RVA antigens were detected using enzyme immunoassay (EIA); the RVA G (VP7) and P (VP4) genotypes were determined by RT-PCR or analysis sequencing. Sixty (24%) out of 254 fecal specimens were positive for RVA by EIA; being 58 (97%) from children ≤2 years of age. RVA prevalence peaks in June and July (coldest and drier months) and the G[P] binary combination observed were G12P[8] (57%); G1P[8] (9%); G12P[6] (6%); and 2% for each of the following genotypes: G1P[6], G2P[6] G4P[6], and G9P[8]. Non-Typeable (NT) G and/or P genotypes were observed as follows: G12P [NT] (6%); G1P [NT], G3P[NT] and GNTP[NT] (4%). Considering the different GP combinations, G12 represented 67% of the genotypes. This is the first data showing the diversity of RVA genotypes in Mozambique highlighting the epidemiological importance of these viruses in acute diarrhea cases in children ≤2 years old. In addition, these findings will provide a baseline data before the introduction of the RVA monovalent (Rotarix(®) ) vaccine in the National Immunization Program in September 2015. J. Med.

    2014-04-01

    Full Text Available Introduction: Diarrheal diseases are a serious health problem and important causes of growth retardation and death in the developing world, especially those of prolonged duration. Since diarrhea is constantly found in children with zinc deficiency, very studies supported zinc supplements beneficial on the duration and severity of diarrhea among children. We review the impact of zinc effects on diarrhea in South-West Asia to update the evidences and to assess its effect on the global burden of diarrhea.   Materials and Methods: We conduct a systematic review through January 2014, for randomized controlled trials relevant to effect of zinc on diarrhea in children. We searched the MeSH terms zinc, acute gastroenteritis and children from various databases of Cochrane Library and PubMed, then clinical trials done in South-West Asia, selected for making written. Results: In recent years, several studies have reported the therapeutic effect of zinc supplementation on diarrheal diseases that was beneficial on decreased episode duration, stool output, stool frequency, hospitalization duration. In some countries in West Asia such as Lebanon, Israel, Saudi Arabia and Iran in clinical trials showed a faster improvement in acute gastroenteritis in children less than five years. But in some countries, such as Turkey, this effect was not significant.   Conclusions: Oral zinc supplementation significantly decreases diarrhea duration and has a greater effect on malnourished children. Zinc supplementation seems to be an appropriate public health strategy, mainly in areas of endemic deficiencies. Global attempts should is increased to support recommended regimen of therapeutic zinc by WHO in all areas. Keywords: Acute Gastroenteritis, Children, Zinc, South-West Asia.  

  4. Infectious Diarrhea: Norovirus and Clostridium difficile in Older Adults.

    White, Mary B; Rajagopalan, Shobita; Yoshikawa, Thomas T

    2016-08-01

    Norovirus infection usually results in acute gastroenteritis, often with incapacitating nausea, vomiting, and diarrhea. It is highly contagious and resistant to eradication with alcohol-based hand sanitizer. Appropriate preventative and infection control measures can mitigate the morbidity and mortality associated with norovirus infection. Clostridium difficile infection is the leading cause of health care-associated diarrhea in the United States. Antibiotic use is by far the most common risk factor for C difficile colonization and infection. Appropriate preventive measures and judicious use of antibiotics can help mitigate the morbidity and mortality associated with C difficile infection. PMID:27394020

    Full Text Available A survey was conducted to determine prevalence of antibodies against Bovine herpes virus-1 (BoHv-1, Bovine herpes virus-4 (BoHv-4 and Bovine viral diarrhea (BVD in dairy cattle in farms with reproductive problems in two areas in Sudan. Sera samples were collected from Khartoum state and central Sudan during 2005-2008 and analyzed using direct ELISA. The prevalence of antibodies was discussed with respect to age, season, sex, breed and locality BoHv-1 and BVD antibodies were highly prevalent in Khartoum state (51.7 and 50.4%, respectively while in central Sudan BoHv-1 (32.7% antibodies were the most prevalent followed by, BVD (25.7% and BoHv-4 (19.3%. The highest prevalence of antibodies against the three viruses in both areas was found during the rainy season (July to October. The prevalence of antibodies to viruses studied was significantly associated with female sex except for BoHv-1. Prevalence of antibodies to BoHv-4 was significantly associated with breed while those of BoHv-1 and BVD were not. The present results indicated that older cattle were more likely to be seropositive in case of BoHv-4 but to BoHv-1 or BVD viruses. Furthermore, it was found that BoHv-1 and BVD antibodies were highly prevalent in aborted dams. While, infertility problems were highly associated with BoHv-1 antibodies. BVD antibodies showed the highest prevalence in case of death after birth. The results of this study provide better understanding of viral epidemics of reproductive disorders and represent the first report of BoHv-4 antibodies in cattle in Sudan.

  4. Prevention and treatment of traveler's diarrhea: a clinical pharmacological approach.

    Scarpignato, C; Rampal, P

    1995-01-01

    Diarrhea represents a major health problem for travelers to developing countries. Although the syndrome is usually self-limited and recovery occurs in the majority of cases without any specific form of therapy, there is a need for safe and effective ways of preventing and treating it. Since the syndrome is most often caused by an infection acquired by ingesting fecally contaminated food or beverages, precautions regarding dietary habits remain the cornerstone of prophylaxis, but dietary self-restrictions do not always translate to reduced rates of diarrheal illness. Administration of probiotics (e.g. lactobacilli or Saccharomyces boulardii) and immunoprophylaxis with the newer oral cholera vaccines have been tried with promising results. Antimicrobials remain, however, the most successful form of prophylaxis, being effective in up to 90% of travelers. For those with impaired health who will take prophylaxis, systemic agents with proved efficacy should be recommended. For other otherwise healthy persons, poorly absorbed agents are preferable in order to avoid the serious, albeit rare, toxicity of systemic drugs. The key factor in the management of acute watery traveler's diarrhea, particularly in infants and young children, is the restoration of water and electrolyte balance. This does not reduce the duration of the illness but will limit dehydration and prevent acidosis. Many patients will require no additional therapy, whereas some will need pharmacologic treatment to shorten the duration of diarrhea or to relieve the accompanying symptoms, like abdominal discomfort, nausea and vomiting. A typical 3- to 5-day illness can be reduced to approximately 1 day by trimethoprim-sulfamethoxazole (TMP-SMX) combination. Some other systemic antimicrobials have been successfully used but, during the last few years, the 4-fluoroquinolone drugs have received considerable attention and have been shown to be highly effective in reducing the duration of traveler's diarrhea.

    Alterations in the gut microbiota are correlated with ailments such as obesity, inflammatory bowel disease, and diarrhea. Up to 60% of individuals traveling from industrialized to developing countries acquire a form of secretory diarrhea known as travelers' diarrhea (TD), and enterotoxigenic Escherichia coli (ETEC) and norovirus (NoV) are the leading causative pathogens. Presumably, TD alters the gut microbiome, however the effect of TD on gut communities has not been studied. We report the first analysis of bacterial gut populations associated with TD. We examined and compared the gut microbiomes of individuals who developed TD associated with ETEC, NoV, or mixed pathogens, and TD with no pathogen identified, to healthy travelers. We observed a signature dysbiotic gut microbiome profile of high Firmicutes:Bacteroidetes ratios in the travelers who developed diarrhea, regardless of etiologic agent or presence of a pathogen. There was no significant difference in α-diversity among travelers. The bacterial composition of the microbiota of the healthy travelers was similar to the diarrheal groups, however the β-diversity of the healthy travelers was significantly different than any pathogen-associated TD group. Further comparison of the healthy traveler microbiota to those from healthy subjects who were part of the Human Microbiome Project also revealed a significantly higher Firmicutes:Bacteriodetes ratio in the healthy travelers and significantly different β-diversity. Thus, the composition of the gut microbiome in healthy, diarrhea-free travelers has characteristics of a dysbiotic gut, suggesting that these alterations could be associated with factors such as travel.

    2009-01-01

    Cholecystocolonic fistula (CF) is an uncommon type of internal biliary-enteric fistulas,which comprise rare complications of cholelithiasis and acute cholecystitis,with a prevalence of about 2% of all biliary tree diseases.We report a case of a spontaneous CF in a 75-year-old diabetic male admitted to hospital for the investigation of chronic watery diarrhea and weight loss.Massive pneumobilia demonstrated on abdominal ultrasound and computerized tomography,along with chronic,bile acid-induced diarrhea and a prolonged prothrombin time due to vitamin K malabsorption,led to the clinical suspicion of the fistula.Despite further investigation with barium enema and magnetic resonance cholangio-pancreatography,diagnosis of the fistulous tract between the gallbladder and the hepatic flexure of the colon could not be established preoperatively.Open cholecystectomy with fistula resection and exploration of the common bile duct was the preferred treatment of choice,resulting in an excellent postoperative clinical course.The incidence of biliary-enteric fistulas is expected to increase due to the parallel increase of iatrogenic interventions to the biliary tree with the use of endoscopic retrograde cholangio-pancreatography and the increased rate of cholecystectomies performed.Taking into account that advanced imaging techniques fail to demonstrate the fistulas tract in half of the cases,and that CFs usually present with non-specific symptoms,our report could assist physicians to keep a high index of clinical suspicion for an early and valid diagnosis of a CF.

  10. Enteric pathogens in stored drinking water and on caregiver's hands in Tanzanian households with and without reported cases of child diarrhea.

    Mia Catharine Mattioli

    Full Text Available BACKGROUND: Diarrhea is one of the leading causes of mortality in young children. Diarrheal pathogens are transmitted via the fecal-oral route, and for children the majority of this transmission is thought to occur within the home. However, very few studies have documented enteric pathogens within households of low-income countries. METHODS AND FINDINGS: The presence of molecular markers for three enteric viruses (enterovirus, adenovirus, and rotavirus, seven Escherichia coli virulence genes (ECVG, and human-specific Bacteroidales was assessed in hand rinses and household stored drinking water in Bagamoyo, Tanzania. Using a matched case-control study design, we examined the relationship between contamination of hands and water with these markers and child diarrhea. We found that the presence of ECVG in household stored water was associated with a significant decrease in the odds of a child within the home having diarrhea (OR = 0.51; 95% confidence interval 0.27-0.93. We also evaluated water management and hygiene behaviors. Recent hand contact with water or food was positively associated with detection of enteric pathogen markers on hands, as was relatively lower volumes of water reportedly used for daily hand washing. Enteropathogen markers in stored drinking water were more likely found among households in which the markers were also detected on hands, as well as in households with unimproved water supply and sanitation infrastructure. CONCLUSIONS: The prevalence of enteric pathogen genes and the human-specific Bacteroidales fecal marker in stored water and on hands suggests extensive environmental contamination within homes both with and without reported child diarrhea. Better stored water quality among households with diarrhea indicates caregivers with sick children may be more likely to ensure safe drinking water in the home. Interventions to increase the quantity of water available for hand washing, and to improve food hygiene, may

    Aslinar

    2014-01-01

    Full Text Available Background Enteropathogenic Escherichia coli (EPEC is a causative agent of intestinal inflammation and microfloral imbalance, leading to diarrhea. The presence of tumor necrosis factor-α (TNF-α in the feces is an indicator of inflammation in the intestinal mucosa. Dadih, (local made of fermented buffalo milk, contains probiotics and is widely consumed by the people in West Sumatera, Indonesia. Weisella paramesenteroides, a probiotic lactic acid bacteria (LAB, has been isolated from dadih and is believed to be useful for improving intestinal microflora balance and inhibiting the activity of harmful microbes. Objective To determine the efficacy of W. paramesenteroides administration in various doses and durations on bowel frequency, stool’s TNF-α levels, and intestinal microflora balance on mice with EPEC-induced diarrhea. Method This randomized experimental animal study examined two factors relating to the effects of W. paramesenteroides on induced diarrhea, namely doses of probiotics (factor A, and durations of observation (factor B. The subjects consisted of 100 male white mice (Mus musculus aged 8 weeks, with weights of 25-30 grams. The outcomes measured were bowel frequency, stool’s TNF-α levels, and the balance of intestinal microflora on mice with EPEC-induced diarrhea. Subjects were divided into 5 groups: the negative control group (received neither EPEC nor probiotic, positive control group (received only EPEC, and three experimental groups (received and different doses of W. paramesenteroides . Probiotics were given twice at the 12-hours and 24-hours for the experimental groups, while the durations of observation consisted of baseline, 12 hours, 24 hours, and 36 hours. Results After 36 hours, subjects with EPEC-induced diarrhea who received W. paramesenteroides administration in doses of 2x108 (A3, were found to have the largest decline of mean defecation (a 4.4-fold decline and the largest decline of stool’s mean TNF-α levels

    Dan Carter; David Olchovsky; Russell Pokroy; David Ezra

    2006-01-01

    Cytomegalovirus (CMV) colitis rarely occurs in immunocompetent patients. We report a case of disabling and life threatening diarrhea in an immunocompetent elderly woman due to CMV colitis. The diagnosis of CMV was based on histological examination of tissues biopsied at colonoscopy, positive CMV antigen and high CMV-IgM titer in peripheral blood samples and a good response to systemic gancyclovir treatment.We conclude that CMV should be considered in the differential diagnosis of colitis in elderly immunocompetent patients.

  20. Porcine epidemic diarrhea virus infection: Etiology, epidemiology, pathogenesis and immunoprophylaxis.

    Jung, Kwonil; Saif, Linda J

    2015-05-01

    Porcine epidemic diarrhea virus (PEDV), a member of the genera Alphacoronavirus in the family Coronaviridae, causes acute diarrhea/vomiting, dehydration and high mortality in seronegative neonatal piglets. For the last three decades, PEDV infection has resulted in significant economic losses in the European and Asian pig industries, but in 2013-2014 the disease was also reported in the US, Canada and Mexico. The PED epidemic in the US, from April 2013 to the present, has led to the loss of more than 10% of the US pig population. The disappearance and re-emergence of epidemic PED indicates that the virus is able to escape from current vaccination protocols, biosecurity and control systems. Endemic PED is a significant problem, which is exacerbated by the emergence (or potential importation) of multiple PEDV variants. Epidemic PEDV strains spread rapidly and cause a high number of pig deaths. These strains are highly enteropathogenic and acutely infect villous epithelial cells of the entire small and large intestines although the jejunum and ileum are the primary sites. PEDV infections cause acute, severe atrophic enteritis accompanied by viremia that leads to profound diarrhea and vomiting, followed by extensive dehydration, which is the major cause of death in nursing piglets. A comprehensive understanding of the pathogenic characteristics of epidemic or endemic PEDV strains is needed to prevent and control the disease in affected regions and to develop an effective vaccine. This review focuses on the etiology, epidemiology, disease mechanisms and pathogenesis as well as immunoprophylaxis against PEDV infection. PMID:25841898

  1. Solanum paniculatum root extract reduces diarrhea in rats

    2016-06-01

    Full Text Available Abstract Solanum paniculatum L., Solanaceae, locally known as "jurubeba", is widely used in Brazil for culinary purposes, and in folk medicine to treat of diverse disorder including gastric dysfunctions. In this study we investigated the antidiarrheal activity of S. paniculatum roots extract in rats at different concentrations (125, 250 and 500 mg/kg, p.o using different experimental models such as castor oil-induced diarrhea, enteropooling and gastrointestinal motility, determined by in vivo experimental models. The major compound of root extract was characterized as chlorogenic acid based in the IR, 1D and 2D NMR analysis. All the extract doses achieved antidiarrheal potency, as indicated by reduced weight of feces in castor oil-induced diarrhea, decreased intestinal motility and significantly inhibited castor oil-induced enteropooling compared to the vehicle group. The highest dose (500 mg/kg produced greater anti-motility effect and better reduction of enteropooling, similar to the reference drug Loperamide (5 mg/kg. Extract from S. paniculatum L. roots had antidiarrheal activity, as shown by the lower weight of the feces as well as decrease in the accumulation of intestinal fluid and slower transit, justifying the traditional use of plant for diarrhea.

    Full Text Available Background: Acute gastroenteritis is a major cause of morbidity and mortality among children in developing countries. Rotaviruses are recognized as the most common etiologic factors of gastroenteritis. In this study, we determined the epidemiologic features, clinical symptoms and molecular structure of rotavirus VP4(P genotypes in children with acute diarrhea in Bahrami Hospital in Tehran Iran, during 2009 for justifying the routine use of rotavirus vaccines in children. Methods: One hundred fifty fecal samples from 150 children with acute diarrhea in Bahrami Pediatric Hospital in Tehran, Iran were collected from January to December 2009. The patients’ mean age was 20.90+18.19 years (ranging from 1 month to 14 years. Fecal samples were transported on ice to the laboratory of virology department of Pasture Institute of Iran. The demographic and clinical data for each case were entered in an author-devised questionnaire. Group A rotavirus was detected by dsRNA-PAGE. Subsequently, rotavirus genotyping (VP4 was performed by semi-nested multiple RT-PCR and the phylogenetic tree of the Rotavirus nucleotides was constructed. The data were analyzed by statistical tests including Wilcoxon signed and Mann-Whitney U. Results: Rotavirus was isolated in 19.3% of the samples, more than 90% of which had long RNA patterns. The predominant genotype (VP4 was P[8] (86% and other genotypes respectively were P[6] (6.9% and P[4] (6.9%. Conclusion: A high prevalence of the P[8] genotype was found to be the cause of acute diarrhea. The analysis of P[8] genotype sequence showed a high level of similarity of the virus in this study with those of other Asian countries.

  3. Conference President's address

    The objective of the Conference is to promote the development of a coherent international policy on the protection of the environment from the effects of ionizing radiation and to foster information exchange on this subject. The organizers, the IAEA in cooperation with United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), the European Commission (EC) and the International Union of Radioecology (IUR), as well as the hosts of the conference, the Government of Sweden through the Swedish Radiation Protection Authority (SSI), are pleased that so nearly 300 delegates from 53 countries have been nominated by their governments to attend this meeting. Another objective is to discuss the implications of the ICRP's proposal for a framework to assess radiation effects in the environment. A framework for radiological protection of the environment must be practical and simple, as should be international standards for discharges into the environment that take account of such an approach. This is a task for the IAEA, in cooperation with other international organizations. This conference therefore provides an opportunity for you to influence the development of both ICRP and IAEA policy in this area. The background session today will give information on the current situation as well as social and political drivers for change. A number of organizations will provide an insight to the present status of international policies on the radiological protection related to releases to the environment. During the course of the conference, there will be five topical sessions that will cover selected subjects related to protection of the environment, such as stakeholders' views, case studies, approaches for non-radioactive pollutants, the state of current scientific knowledge and, finally, the implications of ICRP proposals for international safety standards. Keynote speakers will address key issues within each topical session, and a rapporteur will summarize the

  6. Nosocomial diarrhea: evaluation and treatment of causes other than Clostridium difficile.

    Polage, Christopher R; Solnick, Jay V; Cohen, Stuart H

    2012-10-01

    Diarrhea is common among hospitalized patients but the causes are distinct from those of diarrhea in the community. We review existing data about the epidemiology of nosocomial diarrhea and summarize recent progress in understanding the mechanisms of diarrhea. Clinicians should recognize that most cases of nosocomial diarrhea have a noninfectious etiology, including medications, underlying illness, and enteral feeding. Apart from Clostridium difficile, the frequency of infectious causes such as norovirus and toxigenic strains of Clostridium perfringens, Klebsiella oxytoca, Staphylococcus aureus, and Bacteroides fragilis remains largely undefined and test availability is limited. Here we provide a practical approach to the evaluation and management of nosocomial diarrhea when tests for C. difficile are negative. PMID:22700831

  7. The role of rifaximin in the treatment and chemoprophylaxis of travelers’ diarrhea

    Koo, Hoonmo L; DuPont, Herbert L; Huang, David B

    2009-01-01

    Travelers’ diarrhea is a common illness among international travelers from developed to developing countries. Travelers’ diarrhea is caused by ingestion of contaminated food and water. Bacteria are the primary cause of travelers’ diarrhea. In most surveys, the most common diarrheal pathogen identified is enterotoxigenic Escherichia coli. There are several antimicrobial agents available for the treatment of travelers’ diarrhea including rifaximin which is approved in the United States for the treatment of travelers’ diarrhea due to noninvasive E. coli strains. In this review, we will review the most recent advances of rifaximin for the treatment and prevention of travelers’ diarrhea, with regard to its pharmacokinetics, in vitro susceptibility profile, and efficacy and safety data from clinical trials.

  8. A Case Report of Fungal Diarrhea in a Preweaned Calf in Iran

    Azimpour

    2016-05-01

    Full Text Available Introduction Diarrhea is the most common cause of death in neonatal calves. The most important agents of diarrhea in young calves include bacteria, viruses, and protozoa. Only limited attention has been paid to the role of fungi in calves’ diarrhea. Case Presentation We report on a neonatal calf with fungal diarrhea caused by Candida albicans. The calf has had dysentery in the previous 10 days despite good appetite. The calf was then treated with oxytetracycline tabulations for 5 days. Conclusions Yeasts and molds are sometimes associated with lesions in the stomach or intestines of scouring calves, but there is very limited information about their role in calf diarrhea. In this study, C. albicans was isolated in a 15-day-old dysenteric calf. These organisms are not a primary cause of diarrhea in calves, but like in children, they are possibly opportunistic pathogens that proliferate and invade the intestinal mucosa following antibiotic therapy.

    Management of acute diarrhea remains a global challenge, particularly in resource-limiting countries. Oral rehydration solution (ORS), a passive rehydrating therapy developed approximately 40 years ago, remains the mainstay treatment. Although ORS is effective for hydration, since it does not inhibit enterotoxin-mediated excessive secretion, reduced absorption and compromised barrier function - the primary mechanisms of diarrhea, ORS does not offer a rapid relief of diarrhea symptom.

    Chen, K S; Johnson, D. W.; Muscoplat, C C

    1985-01-01

    Potentiation of the antibody response to inactivated bovine viral diarrhea virus by immunological adjuvants was studied in guinea pigs and cattle. The inactivated bovine viral diarrhea virus alone was demonstrated to be a weak immunogen. Addition of either 2 mg per mL diethylaminoethyl-dextran or 5% alhydrogel to inactivated bovine viral diarrhea virus did not or only slightly stimulated the antibody response; the combined adjuvants induced a significantly higher titer. A higher concentration...

    2014-01-01

    Background In cases of acute diarrhea, it is difficult to distinguish between bacterial and non-bacterial causes. Increased fecal calprotectin (f-CP) level is a marker of neutrophil migration in the intestinal lumen and is associated with intestinal inflammation. Previous studies reported an increase in f-CP levels in children with acute diarrhea, which is caused by bacteria, but only few have studied the relationship between intestinal pathogens with f-CP levels in acute diarrhea.

  15. Observations of IPv6 Addresses

    Malone, David

    2008-01-01

    IPv6 addresses are longer than IPv4 addresses, and are so capable of greater expression. Given an IPv6 address, conventions and standards allow us to draw conclusions about how IPv6 is being used on the node with that address. We show a technique for analysing IPv6 addresses and apply it to a number of datasets. The datasets include addresses seen at a busy mirror server, at an IPv6-enabled TLD DNS server and when running traceroute across the production IPv6 network. The technique quantif...

  20. Protection against diarrhea associated with Giardia intestinalis Is lost with multi-nutrient supplementation: a study in Tanzanian children.

    Jacobien Veenemans

    2011-06-01

    Full Text Available BACKGROUND: Asymptomatic carriage of Giardia intestinalis is highly prevalent among children in developing countries, and evidence regarding its role as a diarrhea-causing agent in these settings is controversial. Impaired linear growth and cognition have been associated with giardiasis, presumably mediated by malabsorption of nutrients. In a prospective cohort study, we aim to compare diarrhea rates in pre-school children with and without Giardia infection. Because the study was conducted in the context of an intervention trial assessing the effects of multi-nutrients on morbidity, we also assessed how supplementation influenced the relationship between Giardia and diarrhoea rates, and to what extent Giardia modifies the intervention effect on nutritional status. METHODS AND FINDINGS: Data were collected in the context of a randomized placebo-controlled efficacy trial with 2×2 factorial design assessing the effects of zinc and/or multi-micronutrients on morbidity (n=612; height-for-age z-score <-1.5 SD. Outcomes measures were episodes of diarrhea (any reported, or with ≥3 stools in the last 24 h and fever without localizing signs, as detected with health-facility based surveillance. Giardia was detected in stool by enzyme-linked immunosorbent assay. Among children who did not receive multi-nutrients, asymptomatic Giardia infection at baseline was associated with a substantial reduction in the rate of diarrhea (HR 0.32; 0.15-0.66 and fever without localizing signs (HR 0.56; 0.36-0.87, whereas no such effect was observed among children who received multi-nutrients (p-values for interaction 0.03 for both outcomes. This interaction was independent of age, HAZ-scores and distance to the research dispensary. There was no evidence that Giardia modified the intervention effect on nutritional status. CONCLUSION: Although causality of the Giardia-associated reduction in morbidity cannot be established, multi-nutrient supplementation results in a loss

    2008-01-01

    Full Text Available Background/Aims: The objective of this study was to describe patients with chronic diarrhea and abnormal skin hyperpigmentation with distinct distribution. Methods: This is a retrospective review of children who presented with diarrhea and skin hyperpigmentation. The clinical presentation, laboratory investigations as well as endoscopic and histological data were reviewed. Results: Seven patients with chronic diarrhea had abnormal skin hyperpigmentation with distinct distribution and presented in the first two months of life. Six patients had other features such as abnormal hair and facial dysmorphism. Mental retardation was reported in one patient. Consanguinity was positive in six patients, and there was family history of consanguinity in four patients, with two patients being siblings. No significant immunodeficiency was reported. Intestinal biopsies were obtained in six patients and showed active chronic inflammation in three patients, partial villous atrophy in two patients, and eosinophilic infiltrate with mild villous atrophy in one patient. Colonic biopsies showed mild focal colitis in three patients and mild colitis with eosinophilic infiltrate in one patient. Skin biopsies showed a greater number of melanophagies with fibrosis of papillary derma in two patients but skin biopsy was normal in one patient. The hair of two patients was analyzed by electron microscopy, which showed an abnormal pattern with decreased pigmentation and diameter; however, its chemical analysis was normal. Two other patients had trichorrhexis nodosa, but no abnormalities were seen in one patient. Chromosomal number was normal in three patients. One patient died because of sepsis, and only one patient was dependent on total parenteral nutrition. Conclusions: We believe that this association might represent a new syndrome with an autosomal recessive inheritance that warrants further studies.

  2. Bovine Viral Diarrhea Virus-Associated Disease in Feedlot Cattle.

    Larson, Robert L

    2015-11-01

    Bovine viral diarrhea virus (BVDv) is associated with bovine respiratory disease complex and other diseases of feedlot cattle. Although occasionally a primary pathogen, BVDv's impact on cattle health is through the immunosuppressive effects of the virus and its synergism with other pathogens. The simple presence or absence of BVDv does not result in consistent health outcomes because BVDv is only one of many risk factors that contribute to disease syndromes. Current interventions have limitations and the optimum strategy for their uses to limit the health, production, and economic costs associated with BVDv have to be carefully considered for optimum cost-effectiveness.

  3. Recurrent diarrhea as a manifestation of temporal lobe epilepsy

    Tomohiko Murai

    2014-01-01

    Full Text Available A woman with temporal lobe epilepsy manifesting with repeated episodes of sudden diarrhea and loss of consciousness is reported. A 63-year-old, right-handed female presented with chief complaints of sudden diarrhea and loss of consciousness for almost three decades. The first attack occurred in her 30s, and similar attacks repeated several times in a year. Her attacks comprised abrupt abdominal discomfort, diarrhea, sudden emergence of old memories relating to when she had played with her brother in her childhood, and loss of consciousness during defecation. She had no convulsion or automatism and fully recovered in a few minutes. Every time she was transferred to emergency hospital by ambulance, she had examinations such as blood test, head computed tomography, electrocardiogram, abdominal ultrasound, and electroencephalography (EEG, but no specific diagnosis was made. On admission to our hospital, vital signs, neurological examination, and blood tests did not show abnormal findings. During long-term video-EEG monitoring for 40 h, she had no habitual event. Interictal EEG showed intermittent irregular delta waves and sharp regional transients in the left anterio-midtemporal area. Sharp transients were not as outstanding from background activities as to be defined as epileptiform discharges, but they were reproducible in morphology and distribution and appeared not only in sleep but also in wakefulness. Brain magnetic resonance imaging was unremarkable. Single-photon emission computed tomography showed a decrease of blood flow in the left frontal and temporal lobes. Wechsler Adult Intelligence Scale—III showed a decline of verbal comprehension. We concluded that the patient was suffering from partial epilepsy originating from the left temporal lobe. Carbamazepine markedly improved her seizures. Temporal lobe epilepsy can manifest with diverse autonomic symptoms and signs. Abdominal sensations often herald the onset of epileptic seizures

  4. Bovine virus diarrhea virus in free-living deer from Denmark.

    Nielsen, S S; Roensholt, L; Bitsch, V

    2000-07-01

    Free-living deer are suggested as a possible source of infection of cattle with bovine virus diarrhea (BVD) virus. To examine this hypothesis blood samples from 476 free-living deer were collected during two different periods and tested for BVD virus and antibody in Denmark. In 1995-96, 207 animals were tested. These included 149 roe deer (Capreolus capreolus), 29 fallow deer (Dama dama), 20 red deer (Cervus elaphus) and one sika deer (Cervus sika). For the remaining eight animals no species information was available. In 1998-99, 269 animals were tested including 212 roe deer and 57 red deer. The animals were selected from areas with a relatively high prevalence of cattle herds with a BVD persistent infection status in 1997 and 1998. All 207 samples from 1995-96 were found antibody-negative except two samples from red deer. Only 158 of the 207 samples were tested for virus and were all found negative. Of the 269 samples from 1998-99 all but one were antibody negative. The positive sample was from a red deer. All samples were virus-negative. It appears that BVD infection does not occur in roe deer in Denmark. The presence of antibody in a few red deer from various districts in Jutland probably results from cattle to deer transmission, rather than spread among deer. Hence, the possibility of free-living deer as a source of infection for cattle in Denmark seems to be remote. PMID:10941751

    2015-06-01

    Full Text Available To explore the expected role of Bovine Viral Diarrhea Virus (BVDV in pneumonia in cattle, cattle lungs (n=242 showing signs of pneumonia were collected from slaughter houses of three different localities located at Northern, Central and Western Sudan during 2010–2013. The collected samples were tested for the presence of BVDV antigen using Enzyme-Linked Immunosorbent Assay (ELISA, and Fluorescent Antibody Test (FAT. Twenty six (10.7% out of 242 samples were found to be positive for BVDV. Positive results were seen in all the three studied areas, with the highest prevalence (16.7%; n=4/24 at Gezira State in Central Sudan. BVDV genome could be detected in all ELISA positive samples. The results indicated the existence of BVDV infection in cattle in different areas in Sudan, and its possible association with respiratory infections in cattle. Analysis using BLAST indicated that the sequence was identical to the previously reported BVDV-1 (GenBank accession AF220247.1.; nucleotide A was found in our study at position 9 of our sequence, whereas T was present instead in the reference virus. This is the first report of detecting BVDV antigen, genome, and its sequence analysis collected from cattle lungs in Sudan.

    The structure genes spike (S), nucleocapsid (N), membrane (M), small membrane (sM) of a porcine epidemic diarrhea virus (PEDV) strain DX isolated in Gansu province, North-west of China, were cloned, sequenced and compared with published sequences of PEDV strains. The nucleotide sequences encoding the entire S, sM, M and N genes open reading frame (ORF) of DX were 4 152, 231, 681 and 1 326 bases long respectively. There were transcription regulatory sequences (TRSs) upstream of the initiator ATG of the S, N and M genes. The amino acids sequences of S, M and N contained 30, 3 and 7 potential asparagine (N)-linked glycosylation sites. Homologous analysis and phylogenetic trees showed that DX had the closest relationship with strains LJB/06, JS-2004-2Z and CH/HLJH/06 that were also isolated from China and indicated the prevalence of some PEDV isolates in China were widespread since the JS-2004-2Z strain originated from the south of the China, and LJB/06 and CH/HLJH/06 were isolated from northeast China. The N gene was cloned using two primers which contained Nco I and BamH I restriction enzyme sites and subcloned into expression vector pET30a. The recombinant plasmid was then transformed into E.coli Rossta. SDS-PAGE showed there was a protein of about 55kDa as expected and Western blot indicated the N protein had biological activity.

  7. Bovine viral diarrhea virus structural protein E2 as a complement regulatory protein.

    Ostachuk, Agustín

    2016-07-01

    Bovine viral diarrhea virus (BVDV) is a member of the genus Pestivirus, family Flaviviridae, and is one of the most widely distributed viruses in cattle worldwide. Approximately 60 % of cattle in endemic areas without control measures are infected with BVDV during their lifetime. This wide prevalence of BVDV in cattle populations results in significant economic losses. BVDV is capable of establishing persistent infections in its host due to its ability to infect fetuses, causing immune tolerance. However, this cannot explain how the virus evades the innate immune system. The objective of the present work was to test the potential activity of E2 as a complement regulatory protein. E2 glycoprotein, produced both in soluble and transmembrane forms in stable CHO-K1 cell lines, was able to reduce complement-mediated cell lysis up to 40 % and complement-mediated DNA fragmentation by 50 %, in comparison with cell lines not expressing the glycoprotein. This work provides the first evidence of E2 as a complement regulatory protein and, thus, the finding of a mechanism of immune evasion by BVDV. Furthermore, it is postulated that E2 acts as a self-associated molecular pattern (SAMP), enabling the virus to avoid being targeted by the immune system and to be recognized as self. PMID:27038454

    We sought to investigate the magnitude, clinical features, treatment, and outcome of children suffering from hypernatremic diarrhea and to identify risk factors for fatal outcome among them. We reviewed 2 data sets of children hypernatremia (serum sodium ≥150 mmol/L): (a) March 2001 to March 2002 (n = 371) and (b) March 2009 to August 2011 (n = 360). We reviewed their records and collected relevant information for analyses. The prevalence of hypernatremia was 5.1% (371/7212) and 2.4% (360/15 219), case fatality rate was 15% and 19%, respectively. In logistic regression analysis, the risk for death significantly increased in association with serum sodium ≥170 mmol/L, nutritional edema, hypoglycemia, respiratory distress, and absent peripheral pulses and reduced with the sole use of oral rehydration salts (ORS) or ORS following intravenous fluid, if indicated (for all, P hypernatremia using only ORS or ORS following intravenous fluid may help reduce the number of deaths.

    Rastyani

    2015-11-01

    Full Text Available Background Enteritis caused by Campylobacter is considered as the most common acute bacterial diarrhea around the world. In most cases, infection occurs as a result of consuming contaminated water or food, especially raw meat of fowls. Objectives The purpose of the present study was to determine the prevalence and antibiotic resistance of campylobacter species among pediatrics of Hamadan city, Iran. Patients and Methods A total of 120 stool samples from children less than 10 years old were examined from January 2013 to December 2014 in Hamadan, Iran. The samples were incubated in Campy-Thio enrichment medium for 1 - 2 hours and then cultured on a specific medium; after that, the suspected colonies were analyzed for Campylobacter spp. identification by conventional tests. The identified species by biochemical methods were confirmed by polymerase chain reaction (PCR. Antimicrobial susceptibility testing was performed by disk agar diffusion (DAD method. Results Twelve (10% Campylobacter spp. from 120 stool samples were isolated including C. coli and C. jejuni. In the antibiotic susceptibility test, the most frequent resistance was observed to ciprofloxacin 8 (88.8%, followed by 7 (77.7% resistant strains to tetracycline, 7 (77.7% to erythromycin, 6 (66.6% to clindamycin, 5 (55.5% to meropenem, 4 (44.4% to gentamicin, 3 (33.3% to nalidixicacid and only 1 (11.1% to chloramphenicol. Conclusions Campylobacter is responsible for some important clinical problems such as enteritis and is also associated with meningitis and hemolytic-uremic syndrome. It is imperative to monitor the prevalence and antibiotic resistance of Campylobacter spp. as well as other the zoonotic bacteria.

  10. Molecular characterization of clinical isolates of Cyclospora cayetanensis from patients with diarrhea in India

    P Yadav

    2015-01-01

    Full Text Available Purpose: Cyclospora cayetanensis is an intestinal coccidian protozoan that has emerged as an important cause of both epidemic and endemic protracted diarrhea worldwide. Though humans appear to be the only natural hosts; the role of animals as natural reservoir is uncertain but of increasing concern. The present study aimed to study the prevalence of coccidian in different groups such as immunocompromised, clinically apparent immunocompetent and healthy individuals. Also, the study isolates were assessed for heterogeneity among the sequences. Materials and Methods: Stool samples from different groups of patients were collected. The parasite was detected in stool by different diagnostic tools such as light microscopy and nested PCR-restriction fragment length polymorphism using 18S ribosomal RNA as the target gene. Results: The prevalence of C. cayetanensis was 2.4% (19/800 in the present study. The PCR assay amplified Cyclospora cayetanensis DNA in only 89% (17/19 isolates. Further, sequencing revealed no significant difference among the study isolates and the non-primates. Phylogenetic analysis of the study isolates however, formed two clusters. While one cluster showed close evolutionary association with the C. cayetanensis strains, the other cluster showed evolutionary association with the two non-primate species. Conclusion: The methods described here for detection of C. cayetanensis oocysts are simple, efficient, specific, and sensitive and therefore can be effectively applied for laboratory diagnosis and environmental assessment of fresh produce and water sources. Clinicians should include Cyclospora infection in the differential diagnosis of prolonged or relapsing diarrheal illness even in clinically apparent immunocompetent individuals.

  11. Adherence to zinc supplementation guidelines for the treatment of diarrhea among children under–five in Uttar Pradesh, India

    2015-12-01

    Full Text Available There is limited evidence on adherence to the recommended dose and duration of zinc supplementation for diarrheal episodes in children under five years of age. In selected districts of Uttar Pradesh, India, we sought to assess adherence to the nationally advised zinc treatment regimen (ie, 10 mg/day for ages 2–6 months and 20 mg/day for ages 7–59 months for 14 days among caregivers of zinc–prescribed children. We identified and conducted follow–up visits to children advised zinc for the treatment of diarrhea. At the initial visit, we collected data on the treatment instructions received from providers. Caregivers were asked to record treatments administered on a pictorial tracking form and were asked to retain all packaging for collection at follow–up. We quantified the average dose and duration of zinc therapy and built logistic regression models to assess the factors associated with caregiver adherence to national guidelines. Caregivers administered zinc for an average of 10.7 days (standard deviation (SD = 3.9 days; median = 13 days, and 47.8% continued treatment for the complete 14 days. Among children receiving zinc syrups and tablets respectively, the age appropriate dose was received by 30.8% and 67.3%. Adherence to age appropriate dose and continuation of zinc for 14 days were highly associated with having received appropriate provider instructions. Our results indicate moderate–to–good adherence to national zinc treatment guidelines for diarrhea among caregivers in rural India. Our findings also highlight the importance of provider guidance in ensuring adherence to zinc dose and duration. Programs aiming to scale–up zinc treatment for childhood diarrhea should train providers to successfully communicate dosing instructions to caregivers, while also addressing the tendency of caregivers to terminate treatment once a child appears to have recovered from an acute diarrheal episode.

  12. Management of acute diarrhea in children by community pharmacists in Lagos, Nigeria

    2014-03-01

    Full Text Available Background: Acute diarrhea in children leads to dehydration and death if not appropriately managed. World Health Organization (WHO recommends treating diarrhea with oral rehydration therapy (ORT, fluids and foods. Proper management is hinged on accurate assessment of patients to identify the acute watery diarrhea. Objective: To compare the knowledge and attitude of community pharmacists in the management of acute diarrhea in children with their observed practice. Methods: This study was carried out using two instruments: structured self-administered questionnaire to assess knowledge and attitude of community pharmacists in the management of acute diarrhea in children and simulated patient visits to evaluate assessment of patients, recommendation of products and instructions on feeding and fluid intake. The simulated patient visits were done in 186 pharmacies in the city of Lagos, Nigeria. Results: The study reveals that the knowledge and attitude of community pharmacists in the management of acute diarrhea in children was different from their observed practice. The difference was statistically significant (p<0.05. During the simulations, 23% carried out appropriate assessment before recommending any products, and 15% recommended ORT alone. Although information to the pharmacists indicated non-dysentery, non-cholera, acute watery diarrhea, antibiotics and antidiarrheals were irrationally recommended and these were the mainstay of symptoms’ management in practice. Questionnaire data revealed that 24% of pharmacists knew the correct instructions to give on food and fluid intake during diarrhea, whereas 8% followed WHO guideline on food and fluid intake during the visits. Conclusions: Assessment of patients to determine acute diarrhea was inadequate. Observed practice in managing acute diarrhea in children was inappropriate and significantly different from their claims in the questionnaire. The recommendation of ORT was scanty and advice on food

    2009-05-01

    Full Text Available Abstract Background Diarrhea causes an estimated 2.5 million child deaths in developing countries each year, 35% of which are due to acute diarrhea. Zinc and copper stores in the body are known to be depleted during acute diarrhea. Our objectives were to evaluate the efficacy of zinc and copper supplementation when given with standard treatment to children with acute watery or bloody diarrhea. Methods We conducted a double-blind randomized controlled clinical trial in the Department of Pediatrics at Indira Gandhi Government Medical College Nagpur, India. Eight hundred and eight children aged 6 months to 59 months with acute diarrhea were individually randomized to placebo (Pl, zinc (Zn only, and zinc and copper (Zn+Cu together with standard treatment for acute diarrhea. Results The mean duration of diarrhea from enrolment and the mean stool weight during hospital stay were 63.7 hours and 940 grams, respectively, and there were no significant differences in the adjusted means across treatment groups. Similarly, the adjusted means of the amount of oral rehydration solution or intravenous fluids used, the proportion of participants with diarrhea more than 7 days from onset, and the severity of diarrhea indicated by more than three episodes of some dehydration or any episode of severe dehydration after enrolment, did not differ across the three groups. Conclusion The expected beneficial effects of zinc supplementation for acute diarrhea were not observed. Therapeutic Zn or Zn and Cu supplementation may not have a universal beneficial impact on the duration of acute diarrhea in children. Trial registration The study was registered as an International Standard Randomized Controlled Trial (ISRCTN85071383.

    Banapurmath, C R; Jayamony, S

    1994-06-01

    Eighty eight severely malnourished preschool children (Grade III or Grade IV, IAP classification) were studied to find out the prevalence of urinary tract infection (UTI). Fifty three well nourished preschool children served as controls. Urine samples were collected by suprapubic aspiration in children below 3 years and in older children a clean catch midstream sample of urine was collected. The urine samples were subjected to direct microscopic examination, Gram's stain and culture. UTI was detected in 7 (8%) of the 88 malnourished children. Besides UTI, the other associated infections included respiratory tract infection (31.8%), diarrhea (27.2%) and tuberculous meningitis (12.7%). PMID:7896393

    Full Text Available Children younger than five years are the most vulnerable to diseases and malnutrition. A cross-sectional study was undertaken in rural areas of Nzega district in Tanzania to assess the prevalence and factors of malnutrition among children aged 6-59 months. Simple random sampling technique was used to select a representative sample of households with target children. The study enrolled 460 mother-child pairs from five wards. Data were collected using a semi-structured questionnaire. Child nutritional status was assessed based on anthropometric measurements. The potential contributing factors to malnutrition were also assessed. These included: child feeding practices, socio-demographic characteristics, access to water, sanitation, history of illness episodes (diarrhoea and acute respiratory infection and child immunization status. The survey data were analyzed using SPSS for windows version 17.0 whilst anthropometric data were analysed using the ENA for SMART (2011 software. Almost all children (98.5% were breastfed. It was found that about one quarter (25.6% were breastfed immediately after birth and one third (33.5% received pre-lacteal feeds. Prevalence of stunting (height- for- age Z score <-2, wasting (weight- for-height Z score <-2 and underweight (weight-for-age Z score <-2 were 26.1, 6.5% and 11.7%, respectively. Chronic malnutrition (stunting was significantly (p<0.05 associated with child’s sex and age, mother’s education, number of antenatal care visits (ANC and family size. Others factors were episodes of diarrhea, acute respiratory infection and access to safe water. Overall, the nutritional status of the children is sub-optimal and therefore, attention is needed to address the situation.

  16. Diagnosis and treatment of diarrhea-predominant irritable bowel syndrome

    Lacy BE

    2016-02-01

    Full Text Available Brian E Lacy Division of Gastroenterology and Hepatology, Dartmouth-Hitchcock Medical Center, Lebanon, NH, USA Abstract: Irritable bowel syndrome (IBS is one of the most common gastrointestinal disorders worldwide. The economic impact of IBS on the health care system is substantial, as is the personal impact on patients. Patients with diarrhea-predominant IBS (IBS-D comprise a substantial proportion of the overall IBS population. Primary care providers are often the first point of contact for patients with IBS-D and can accurately diagnose IBS after a careful history and examination without extensive diagnostic tests. Several pharmacologic treatments (eg, loperamide, alosetron, and antidepressants and non-pharmacologic treatments (eg, dietary modification and probiotics are available for IBS-D, but restrictions on use (eg, alosetron or the lack of controlled trial data showing reductions in both global and individual IBS-D symptoms (eg, bloating, pain and stool frequency emphasize the need for alternative treatment options. Two newer medications (eluxadoline and rifaximin were approved in May 2015 for the treatment of IBS-D, and represent new treatment options for this common gastrointestinal condition.

  17. Comparison of endogenous and radiolabeled bile acid excretion in patients with idiopathic chronic diarrhea

    Schiller, L.R.; Bilhartz, L.E.; Santa Ana, C.A. (Baylor Univ. Medical Center, Dallas, TX (USA))

    1990-04-01

    Fecal recovery of radioactivity after ingestion of a bolus of radiolabeled bile acid is abnormally high in most patients with idiopathic chronic diarrhea. To evaluate the significance of this malabsorption, concurrent fecal excretion of both exogenous radiolabeled bile acid and endogenous (unlabeled) bile acid were measured in patients with idiopathic chronic diarrhea. Subjects received a 2.5-microCi oral dose of taurocholic acid labeled with 14C in the 24th position of the steroid moiety. Endogenous bile acid excretion was measured by a hydroxysteroid dehydrogenase assay on a concurrent 72-h stool collection. Both radiolabeled and endogenous bile acid excretion were abnormally high in most patients with chronic diarrhea compared with normal subjects, even when equivoluminous diarrhea was induced in normal subjects by ingestion of osmotically active solutions. The correlation between radiolabeled and endogenous bile acid excretion was good. However, neither radiolabeled nor endogenous bile acid excretion was as abnormal as is typically seen in patients with ileal resection, and none of these diarrhea patients responded to treatment with cholestyramine with stool weights less than 200 g. These results suggest (a) that this radiolabeled bile acid excretion test accurately reflects excess endogenous bile acid excretion; (b) that excess endogenous bile acid excretion is not caused by diarrhea per se; (c) that spontaneously occurring idiopathic chronic diarrhea is often associated with increased endogenous bile acid excretion; and (d) that bile acid malabsorption is not likely to be the primary cause of diarrhea in most of these patients.

    Diarrheal diseases remain a leading cause of morbidity and mortality for children in developing countries, while representing an important cause of morbidity worldwide. The World Health Organization recommended that low osmolarity oral rehydration solutions plus zinc save lives in patients with acute diarrhea, but there are no approved, safe drugs that have been shown to be effective against most causes of acute diarrhea. Identification of abnormalities in electrolyte handling by the intestine in diarrhea, including increased intestinal anion secretion and reduced Na(+) absorption, suggest a number of potential drug targets. This is based on the view that successful drug therapy for diarrhea will result from correcting the abnormalities in electrolyte transport that are pathophysiologic for diarrhea. We review the molecular mechanisms of physiologic regulation of intestinal ion transport and changes that occur in diarrhea and the status of drugs being developed to correct the transport abnormalities in Na(+) absorption that occur in diarrhea. Mechanisms of Cl(-) secretion and approaches to anti-Cl(-) secretory therapies of diarrhea are discussed in a companion review. PMID:24184676

  3. Comparison of endogenous and radiolabeled bile acid excretion in patients with idiopathic chronic diarrhea

    Fecal recovery of radioactivity after ingestion of a bolus of radiolabeled bile acid is abnormally high in most patients with idiopathic chronic diarrhea. To evaluate the significance of this malabsorption, concurrent fecal excretion of both exogenous radiolabeled bile acid and endogenous (unlabeled) bile acid were measured in patients with idiopathic chronic diarrhea. Subjects received a 2.5-microCi oral dose of taurocholic acid labeled with 14C in the 24th position of the steroid moiety. Endogenous bile acid excretion was measured by a hydroxysteroid dehydrogenase assay on a concurrent 72-h stool collection. Both radiolabeled and endogenous bile acid excretion were abnormally high in most patients with chronic diarrhea compared with normal subjects, even when equivoluminous diarrhea was induced in normal subjects by ingestion of osmotically active solutions. The correlation between radiolabeled and endogenous bile acid excretion was good. However, neither radiolabeled nor endogenous bile acid excretion was as abnormal as is typically seen in patients with ileal resection, and none of these diarrhea patients responded to treatment with cholestyramine with stool weights less than 200 g. These results suggest (a) that this radiolabeled bile acid excretion test accurately reflects excess endogenous bile acid excretion; (b) that excess endogenous bile acid excretion is not caused by diarrhea per se; (c) that spontaneously occurring idiopathic chronic diarrhea is often associated with increased endogenous bile acid excretion; and (d) that bile acid malabsorption is not likely to be the primary cause of diarrhea in most of these patients

    Instruments for nuclear signal measurements based on add-on card for a personal computer (PC) are designed often. Then one faces the problem of the addressing of data input/output devices which show an integration level or intelligence that makes the use of several port address indispensable, and these are limited in the PC. The virtual addressing offers the advantage of the occupation of few addresses to accede to many of these devices. The principles of this technique and the appliances of a solution in radiometric in a radiometric card based on programmed logic are discussed in this paper

  9. Reclaiming unused IPv4 addresses

    IT Department

    2016-01-01

    As many people might know, the number of IPv4 addresses is limited and almost all have been allocated (see here and here for more information).   Although CERN has been allocated some 340,000 addresses, the way these are allocated across the site is not as efficient as we would like. As we face an increasing demand for IPv4 addresses with the growth in virtual machines, the IT Department’s Communication Systems Group will be reorganising address allocation during 2016 to make more efficient use of the IPv4 address ranges that have been allocated to CERN. We aim, wherever possible, to avoid giving out fixed IP addresses, and have all devices connected to the campus network obtain an address dynamically each time they connect. As a first stage, starting in February, IP addresses that have not been used for more than 9 months will be reclaimed. No information about the devices concerned will be deleted from LANDB, but a new IP address will have to be requested if they are ever reconnected to t...

  10. Causes of diarrhea in tube-fed patients: a comprehensive approach to diagnosis and management.

    Eisenberg, P G

    1993-06-01

    In the absence of a standard definition for diarrhea, clinicians have developed their own descriptions, such as an increased frequency of stools, an increased quantity of water in the stool, an increased weight of the stool, or a change in the consistency of the stool. The clinician should first determine whether the diarrhea is osmotic or secretory. Diarrhea in patients who receive enteral nutrition is often caused by such conditions as diabetes, malabsorption syndromes, infection, gastrointestinal complications, or concomitant drug therapy instead of the enteral formula. Factors related to the enteral nutrition that may contribute to diarrhea include the composition of the formula, the manner of administration, or bacterial contamination. To ensure that the nutritional requirements of patients are met and the appropriate treatment is administered, all of the possible causes of diarrhea should be considered before discontinuing or reducing the amount of formula delivered.

    Full Text Available Childhood diarrhea continues to be a public health problem in developing countries, including Ethiopia. Detecting clusters and trends of childhood diarrhea is important to designing effective interventions. Therefore, this study aimed to investigate spatiotemporal clustering and seasonal variability of childhood diarrhea in northwest Ethiopia.Retrospective record review of childhood diarrhea was conducted using quarterly reported data to the district health office for the seven years period beginning July 1, 2007. Thirty three districts were included and geo-coded in this study. Spatial, temporal and space-time scan spatial statistics were employed to identify clusters of childhood diarrhea. Smoothing using a moving average was applied to visualize the trends and seasonal pattern of childhood diarrhea. Statistical analyses were performed using Excel® and SaTScan programs. The maps were plotted using ArcGIS 10.0.Childhood diarrhea in northwest Ethiopia exhibits statistical evidence of spatial, temporal, and spatiotemporal clustering, with seasonal patterns and decreasing temporal trends observed in the study area. A most likely purely spatial cluster was found in the East Gojjam administrative zone of Gozamin district (LLR = 7123.89, p <0.001. The most likely spatiotemporal cluster was detected in all districts of East Gojjam zone and a few districts of the West Gojjam zone (LLR = 24929.90, p<0.001, appearing from July 1, 2009 to June 30, 2011. One high risk period from July 1, 2008 to June 30, 2010 (LLR = 9655.86, p = 0.001 was observed in all districts. Peak childhood diarrhea cases showed a seasonal trend, occurring more frequently from January to March and April to June.Childhood diarrhea did not occur at random. It has spatiotemporal variation and seasonal patterns with a decreasing temporal trend. Accounting for the spatiotemporal variation identified in the study areas is advised for the prevention and control of diarrhea.

    Meteorism, abdominal spasms, diarrhea, casually obstipation, flatulence and nausea are symptoms of fructose malabsorption (FIT) and/or lactose intolerance (LIT), but are also symptoms of irritable bowel syndrome (IBS). Therefore these diseases should be considered primarily in patients with digestive complaints. For diagnosis an H(2)-breath test is used.In 1,935 patients (526 m, 1,409 f) a fructose intolerance test and in 1,739 patients (518 m,1,221 f) a lactose intolerance test was done.FIT is found more frequently than LIT (57 versus 52 % in adults (p fructose or lactose may lead to improvement or remission of these metabolic disorders. IBS, which is often correlated with FIT (183/221 patients = 83 %), can be improved by relevant but also not relevant diets indicating that irritable bowel disease seems to be caused primarily by psychological disorders.

  16. Construction of recombinant DNA clone for bovine viral diarrhea virus

    Molecular cloning was carried out on the Danish strain of bovine viral diarrhea virus (BVDV) to construct strategy for the diagnostic tools and effective vaccine of BVD afterwards. A recombinant DNA clone (No. 29) was established successfully from cDNA for viral RNA tailed with adenine homopolymer at 3 -end. 32P-labeled DNA probes of 300~1, 800bp fragments, originating from the clone 29, directed specific DNA-RNA hybridization results with BVDV RNA. Recombinant DNA of the clone 29 was about 5,200bp representing 41.6% of the full length of Danish strain's RNA, and restriction sites were recognized for EooR I, Sst I, Hind III and Pst I restriction enzymes in the DNA fragment

  17. Impact of porcine epidemic diarrhea on performance of growing pigs.

    Julio Alvarez

    Full Text Available The impact of porcine epidemic diarrhea virus (PEDv infection on the US pork industry has mainly been attributed to the mortality that it causes in suckling piglets, and, consequently, much effort has been invested in the quantification of its effect in sow farms. However, no information on the performance of surviving pigs that were exposed to the PEDv as piglets is available. Here, a retrospective cohort study to evaluate the impact of porcine epidemic diarrhea virus (PEDv infection on growing pigs' performance, as indicated by mortality, average daily gain (ADG, average daily feed intake (ADFI, and feed conversion ratio (FCR was performed using production records from weaned pigs in nursery and wean-to-finish sites from sow farms that became PEDv-infected between May 2013 and June 2014. Production records from the first batch of growing pigs weaned in infected flows after the PEDv outbreak ("infected batches" were compared with those from pigs weaned within the previous 14 to 120 days ("control batches". Performance records from infected and control batches, paired by flow, were compared using non-parametric paired tests. Mortality, ADG and FCR were significantly different in PEDv-positive (infected compared with PEDv-negative (control batches, with a mean increase of mortality and FCR of 11% and 0.5, respectively, and a decrease of ADG of 0.16 lb/day. Our results demonstrate a poorer performance of growing pigs weaned after a PEDv outbreak compared with those weaned within the previous 14-120 days, suggesting that in addition to the mortality induced by PEDv in suckling pigs, the disease also impairs the performance of surviving pig. These findings help to quantify the impact of PEDv infection in the US and, ultimately, contribute to efforts to quantify the cost-effectiveness of disease prevention and control measures.

    In a double-blind, randomized trial, 85 adult patients with acute diarrhea (more than three watery stools per day) received either 500 mg of ciprofloxacin twice daily or placebo for five days. Seventy-six patients were evaluated, 38 patients in the ciprofloxacin group (16 with Salmonella species, 19 with Campylobacter jejuni, and three with Shigella species) and 38 patients in the placebo group (21 with Salmonella species, 11 with C. jejuni, and six with Shigella species). The duration of fever in patients treated with ciprofloxacin was 1.3 days versus 3.1 days in the placebo group (p less than 0.05). The mean duration of diarrhea in the ciprofloxacin group was 1.5 days versus 2.9 days in the placebo group (p less than 0.001). The corresponding numbers in patients with salmonellosis were 1.9 versus 3.4 days (p less than 0.01). In the ciprofloxacin group, all stool culture results became negative within 48 hours of treatment. Relapse occurred in four patients with salmonellosis within three weeks after the end of treatment. In the placebo group, only four of 38 patients had negative stool culture results during treatment and results were negative in only 13 at one week after the treatment period (p less than 0.001). Modest transient elevation of serum transaminase levels was detected in three patients in the ciprofloxacin group and in two patients in the placebo group. Epigastric pain occurred in one patient, and leukopenia occurred in one patient in the ciprofloxacin group. Gastrointestinal discomfort was recorded in two patients and rash was found in one patient in the placebo group. PMID:3555057

    Full Text Available Background and Objectives: Shiga toxin-producing Escherichia coli (STEC have emerged as human pathogens and con- tamination via animal origin has been a major public health concern. We compared the distribution of phylogenetic groups and prevalence of stx gene variants among the pathogenic strains of Escherichia coli isolated from feces of diarrheatic calves in Tehran suburb farms.Materials and Methods: In this study we screened 140 diarrheatic calves (1-15 days old for E. coli strains during a 3 months period of time. The isolated strains were grouped into different phylotypes according to the presence of chuA, yjaA and TSPE4.C2 genes. Then, the prevalence of stx gene subtypes was evaluated in the B  phylotypes.Results: From diarrheatic calves, 51 bacterial isolates were biochemically identified as E. coli and 31 isolates out of 51 were considered B  phylotype using DNA Microarray technology. Of these isolates, 20 contained stx a and stx b and one harbored all mentioned variants of stx genes except stx b.Conclusion: This study showed that in Tehran suburb, the B  phylotype of E. coli is prevalent as a causative agent of diarrhea in calves and the prevalence of stx  gene subtypes is dominant in comparison with other subtypes. Considering the possibility that these stx genes can be spread to other strains, bovine E. coli strains are an important source of stx genes for other strains and further study and surveillance seems to be required for the exact identification of virulence profile of E. coli phylotypes in different hosts.Keywords: Escherichia coli, calf diarrhea, B1 phylotype, shiga-like toxin subtypes, Tehran suburb

The fecal microbiome, SCFAs, and serum/urine metabolite profiles were characterized by 454-pyrosequencing of the 16S rRNA genes, GC/MS, and untargeted and targeted metabolomics approach using UPLC/MS and HPLC/MS, respectively. Significantly lower bacterial diversity was observed in dogs with acute diarrhea in regards to species richness, chao1, and Shannon index (p=0.0218, 0.0176, and 0.0033; respectively. Dogs with acute diarrhea had significantly different microbial communities compared to healthy dogs (unweighted Unifrac distances, ANOSIM p=0.0040. While Bacteroidetes, Faecalibacterium, and an unclassified genus within Ruminococcaceae were underrepresented, the genus Clostridium was overrepresented in dogs with acute diarrhea. Concentrations of fecal propionic acid were significantly decreased in acute diarrhea (p=0.0033, and were correlated to a decrease in Faecalibacterium (ρ=0.6725, p=0.0332. The predicted functional gene content of the microbiome (PICRUSt revealed overrepresentations of genes for transposase enzymes as well as methyl accepting chemotaxis proteins in acute diarrhea.

    The authors report a case of congenital chloride diarrhea with molecular confirmation of diagnosis. A 10-mo-old boy presented with failure to thrive, voluminous diarrhea, dehydration, hyponatremia, hypokalemia, metabolic alkalosis and history of maternal polyhydramnios. The diagnosis of congenital chloride diarrhea was based on high fecal and low urinary chloride excretion, in addition to biochemical abnormalities. Genetic testing revealed a novel homozygous mutation in exon 4 of the SLC26A3 gene that encodes the protein regulating chloride bicarbonate absorption in distal ileum and colon. Therapy with oral fluids and electrolytes led to decrease in stool frequency and improvement in growth parameters. PMID:26637435

Laboratory findings showed hypokalemia and excessive production of VIP and catecholamines. After surgical resection of the tumor, diarrhea subsided and both electrolytes and affected hormone levels normalized. Immunohistochemical examination confirmed a diagnosis of pheochromocytoma,which contained VIP-positive ganglion-like cells. We herein present the clinical and histogenetic implications of this rare clinical entity, with literature review.

    Antibiotic-associated diarrhea (AAD) is associated with altered intestinal microflora and other symptoms that may lead to possibly death. In critically ill patients, diarrhea increases rates of morbimortality. Assessing diarrhea risks is thus important for clinicians. For this reason, we conducted a hypothesis-generating study focused on antibiotic-associated diarrhea (AAD) to provide insight into methods of prevention. We evaluated the hypothesis of predisposing factors within the resident intestinal microbiota in a cohort of outpatients receiving antibiotherapy. Among the pool of tested variables, only those related to bacterial 16S rRNA genes were found to be relevant. Complex statistical analyses provided further information: amid the bacteria 16S rRNA genes, eight were determined to be essential for diarrhea predisposition and characterized from the most important to the least. Using these markers, AAD risk could be estimated with an error of 2%. This molecular analysis offers new perspectives for clinical applications at the level of prevention. PMID:20186408

  11. A 3-YEAR FOLLOW-UP OF A BRAZILIAN AIDS PATIENT WITH PROTRACTED DIARRHEA CAUSED BY Enterocytozoon bieneusi

    1998-07-01

    Full Text Available Enterocytozoon bieneusi is the most prevalent microsporidian parasite that causes gastrointestinal infection in persons with AIDS. Microsporidia are increasingly recognized as important opportunistic pathogens all over the world but in Brazil only few cases have been reported due either to the non awareness of the clinical presentation of the disease or to difficulties in the laboratory diagnosis. We report a 3-year follow-up of a Brazilian HIV-positive patient in whom microsporidial spores were detected in stools and were identified as E. bieneusi using electron microscopy and PCR. The patient presented with chronic diarrhea, CD4 T-lymphocytes count below 100/mm3 and microsporidial spores were consistently detected in stools. Albendazole was given to the patient in several occasions with transient relief of the diarrhea, which reappeared as soon as the drug was discontinued. Nevertheless, a diarrhea-free period with weight gain up to 18 Kg occurred when a combination of nucleoside and protease inhibitors was initiated as part of the antiviral treatment.Enterocytozoon bieneusi é o mais comum microsporídio agente de infecções gastrointestinais que ocorre predominantemente em pessoas com AIDS. Em todo o mundo os microsporídios são reconhecidos como importantes patógenos oportunistas, entretanto poucos casos já foram diagnosticados no Brasil, provavelmente devido ao pouco conhecimento do quadro clínico que os agentes produzem ou a dificuldades no diagnóstico laboratorial. No presente trabalho relatamos o caso de um paciente brasileiro HIV-positivo acompanhado durante 3 anos, em que foram detectados esporos de microsporídios nas fezes, identificados como Enterocytozoon bieneusi por microscopia eletrônica e PCR. O paciente apresentava diarréia crônica, contagem de linfócitos CD4 abaixo de 100/mm3 e fez uso de albendazol em diferentes ocasiões com melhora transitória da diarréia, que reaparecia logo que a droga era suspensa

    of the OIE List, including foot and mouth disease and classical swine fever. However, several infectious diseases are known to remain among herds, which produce a major effect in production due to losses by abortion, decrease of fertility and what it is more important, some of them represent barriers for export and constitute a risk of zoonosis for the population. In this work, a monitoring system based on the analysis of bulk milk antibodies by means of ELISA test, was implemented to study the epidemiology and distribution of 4 of the main bovine diseases that currently affect the IX Region of Chile (brucellosis, bovine leukaemia, IBR and BVD. The system allowed the surveillance of 279 dairies, which represented 43% of the dairies registered in IX the Region, and included 19,635 milking cows (14%. With this system, a high prevalence for leukaemia (59%, IBR (76% and BVD (96% could be established, whereas it was confirmed that brucellosis is restricted to a few dairies (5%. The surveillance system coupled to the satellite geographic information analysis, allowed to establish the space distribution of these diseases in the different communes of the Region, demonstrating to be an excellent and low cost support tool for the monitoring of the diseases in the herd, which guarantees the possibility of establishing this platform in the Region and its feasibility to project it at national level.

    2016-02-01

    Food-handlers with poor personal hygiene working in food-service establishments could be potential sources of infection due to pathogenic organisms. In May 2011, a cross-sectional study was undertaken to determine the prevalence of bacteria and intestinal parasites among food-handlers working with Cuban health personnel in Haiti. Stool specimens were collected from 56 food-handlers and samples were examined using standard procedures. Of the food handlers, 26.8% had one bacterial or intestinal parasite. The most prevalent species of organism found were Blastocystis spp. (9%), followed by Vibrio cholerae O1 serotype Ogawa, Aeromonas spp. and Giardia intestinalis, each one with 4%. The prevalence of intestinal parasites was 19.7%. Five out of 56 food handlers had diarrhea at the time the study was conducted. It was found that there was a lower prevalence of V. cholerae O1 serotype Ogawa in comparison to intestinal parasites. The study highlights the importance of the precautions that must be taken in cholera-affected countries by medical teams and their organizations, with emphasis on the preparation, processing, and serving of meals. The recommendation is to intensify continuing education programs, periodical laboratory examinations to detect carriers and food-handlers reporting sick, and to observe strict adherence to hygienic food-handling practices. In addition, food handlers with diarrhea should refrain from preparation or delivery of food. PMID:27077312

    Candida infection in the small intestine is uncommon. We report an unusual case of duodenal candidiasis that presented as chronic diarrhea in a patient who had previously undergone kidney transplantation. A 60-year-old man presented with profuse watery diarrhea that had lasted 6 months 13 years after kidney transplantation. Upper gastrointestinal endoscopy results indicated candidiasis within the esophagus and duodenum. Biopsy results revealed active duodenitis with hyphal and yeast forms of Candida overlying the duodenal epithelium in periodic acid Schiff staining. The patient was successfully treated with fluconazole. After 6 months of follow-up, the patient had no complaint of diarrhea. Duodenal candidiasis may be the result of chronic diarrhea in patients with a history of kidney transplantation. PMID:25362226

    The diarrhea case pattern information, especially for toddler, is very important. It is used to show the distribution of diarrhea in every region, relationship among that locations, and regional economic characteristic or environmental behavior. So, this research uses spatial pattern to perform them. This method includes: Moran's I, Spatial Autoregressive Models (SAR), and Local Indicator of Spatial Autocorrelation (LISA). It uses sample from 23 sub districts of Bekasi Regency, West Java, Indonesia. Diarrhea case, regional economic, and environmental behavior of households have a spatial relationship among sub district. SAR shows that the percentage of Regional Gross Domestic Product is significantly effect on diarrhea at α = 10%. Therefore illiteracy and health center facilities are significant at α = 5%. With LISA test, sub districts in southern Bekasi have high dependencies with Cikarang Selatan, Serang Baru, and Setu. This research also builds development application that is based on java and R to support data analysis.

  20. An outbreak of Clostridium difficile-associated diarrhea in piglets in Brazil

    Rodrigo Otávio Silveira Silva

    2014-02-01

    Full Text Available In spite of the substantial role of Clostridium difficile in causing diarrhea in piglets, there have been few reports of the disease caused by this bacterium in Rio Grande do Sul, Brazil. In this paper, we describe an outbreak of C. difficile-associated diarrhea in a pig farm in Brazil. The diarrhea rate increased in piglets 1-to-7 days old from an average of 2% to approximately 20%. Necropsied piglets showed mesocolon edema, and in a histological evaluation, severe necrotizing neutrophilic colitis was observed. The intestinal contents were positive for the A/B toxins of C. difficile and negative for other tested enteropathogens. The association between the clinical signs, post mortem findings and laboratory exams confirmed the diagnosis of C. difficile-associated diarrhea. The present report confirms C. difficile as a pathogen in swine in Brazil and highlights the need for up to date routine laboratory protocols for the diagnosis of this disease in swine.

    Parasite prevalence (the proportion of infected hosts) is a common measure used to describe parasitaemias and to unravel ecological and evolutionary factors that influence host–parasite relationships. Prevalence esti- mates are often based on small sample sizes because of either low abundance of the hosts or logistical problems associated with their capture or laboratory analysis. Because the accuracy of prevalence estimates is lower with small sample sizes, addressing sample size h...

  2. Management of children with prolonged diarrhea [version 1; referees: 3 approved

    Antonietta Giannattasio

    2016-02-01

    Full Text Available Prolonged diarrhea is usually defined as acute-onset diarrhea lasting 7 days or more, but less than 14 days. Its trend has been declining in recent years because of improvement in the management of acute diarrhea, which represents the ideal strategy to prevent prolonged diarrhea. The pathogenesis of prolonged diarrhea is multifactorial and essentially based on persistent mucosal damage due to specific infections or sequential infections with different pathogens, host-related factors including micronutrient and/or vitamin deficiency, undernutrition and immunodeficiency, high mucosal permeability due to previous infectious processes and nutrient deficiency with consequential malabsorption, and microbiota disruption. Infections seem to play a major role in causing prolonged diarrhea in both developing and developed areas. However, single etiologic pathogens have not been identified, and the pattern of agents varies according to settings, host risk factors, and previous use of antibiotics and other drugs. The management of prolonged diarrhea is complex. Because of the wide etiologic spectrum, diagnostic algorithms should take into consideration the age of the patient, clinical and epidemiological factors, and the nutritional status and should always include a search for enteric pathogens. Often, expensive laboratory evaluations are of little benefit in guiding therapy, and an empirical approach may be effective in the majority of cases. The presence or absence of weight loss is crucial for driving the initial management of prolonged diarrhea. If there is no weight loss, generally there is no need for further evaluation. If weight loss is present, empiric anti-infectious therapy or elimination diet may be considered once specific etiologies have been excluded.

    2008-02-01

    Full Text Available Diarrhea remains a major health issue in developing countries, with high morbidity and mortality rates. Determining the incidence of acute diarrhea in children and its associated factors is crucial to the planning of preventive approaches. The objective of this study was to determine the incidence of diarrhea and to assess some relevant associated factors to it in children younger than 40 months living in two slums of Salvador, Brazil. This is the first prospective cohort, community-based study that was performed in two periurban slums of Salvador, Brazil. Eighty-four children younger than 40 months were randomly selected and visited every other day for one year. The chi-square test was used to evaluate the occurrence of diarrhea and its associated factors. During the surveillance period, 232 diarrhea episodes were identified, resulting in an incidence rate of 2.8 episodes/child/year. In average (mean value of 84 children,each child suffered 11.1 days of diarrhea per year, yielding an average duration of 3.9 days per episode. The highest incidence rates were found among children under one year old. Early weaning, male sex, malnutrition, having a mother younger than 25 years or who considered her child malnourished, missed immunizations and previous pneumonia were associated factors for suffering diarrheal episodes. The rates of incidence and duration of diarrhea that we found are in accordance to those reported by others. Additionally, our results reinforce the importance of environmental and health-related associated factors to the onset of diarrhea.

    Full Text Available To determine the effective factors on persistent diarrhea in under five year old children (UN5, a total of 1341 subjects were selected between cases referred to Sanandaj children hospital for diarrhea in the period between 1st June and 22nd October 1994. The children were questioned for prolongation of diarrheal episode after 14 days of its onset. The investigation showed that the duration of diarrhea was prolonged for fourteen days and more in 103 out of 1341 children (7.7%. In other words, 92.3% of children recovered before 14th days. The incidence of persistent diarrhea was usually greatest during the first year of life (P=0.00. Duration of diarrheal episode in children who were breast fed is shorter than in those who were not breast fed (P=0.00. Inappropriate use of antibiotic may favor the over growth of pathogenic or commensal bacteria in the proximal intestine to persistent diarrhea. Diarrhea became persistent 4 times more in children whose stool was mucus or bloody at the onset than those with water stool (P=0.00.

    2016-01-01

    Patient: Male, 46 Final Diagnosis: Celiac crisis Symptoms: Abdominal pain • chronic diarrhea • lightheadedness • weakness • weight loss Medication: — Clinical Procedure: — Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: Celiac disease is a hypersensitivity enteropathy that can have various presentations in adults. Rarely, patients can present with severe lab abnormalities, dehydration and weight loss caused by celiac disease – a celiac crisis. Case Report: A 46-year-old male with a past medical history significant for diabetes mellitus, type 2 (DM2) and recently treated Bell’s Palsy presented to the emergency room complaining of weakness, diarrhea and lightheadedness. On presentation, the patient had a systolic blood pressure (SBP) of 60 mm Hg and a lactic acidosis with pH of 7.28. Infectious etiologies of diarrhea were ruled out. The patient had an EGD which showed erythema of the duodenal bulb. Serum anti-gliadin and anti-TTG IgA were both elevated suggesting Celiac disease. Biopsies showed histopathology consistent with celiac disease. The patient’s diarrhea resolved after initiation of a gluten free diet. He gained 25 kilograms after discharge and did not require further hospitalizations for diarrhea. Conclusions: Celiac crisis is a very rare presentation of celiac disease in adults but nonetheless should be considered in patients with marked metabolic derangements in the setting of osmotic diarrhea. Treatment consists of a gluten free diet and may require management with steroids and total parenteral nutrition (TPN). PMID:27492679

    Full Text Available Infectious diarrhea, a common disease of children, deserves permanent monitoring in all social groups. To know the etiology and clinical manifestations of acute diarrhea in children up to 5 years of age from high socioeconomic level households, we conducted a descriptive, microbiological, and clinical study. Stools from 59 children with acute community-acquired diarrhea were examined, and their parents were interviewed concerning symptoms and signs. Rotavirus, adenovirus, and norovirus were detected by commercially available qualitative immunochromatographic lateral flow rapid tests. Salmonella, Campylobacter, Yersinia, and Shigella were investigated by standard bacteriological methods and diarrheagenic E. coli by PCR assays. We identified a potential enteric pathogen in 30 children. The most frequent causes of diarrhea were enteropathogenic E. coli (EPEC, viruses, Campylobacter, Salmonella, and Shiga-toxin-producing E. coli (STEC. Only 2 patients showed mixed infections. Our data suggest that children with viral or Campylobacter diarrhea were taken to the hospital earlier than those infected with EPEC. One child infected with STEC O26 developed “complete” HUS. The microbiological results highlight the importance of zoonotic bacteria such as atypical EPEC, Campylobacter, STEC, and Salmonella as pathogens associated with acute diarrhea in these children. The findings also reinforce our previous communications about the regional importance of non-O157 STEC strains in severe infant food-borne diseases.

    Full Text Available A 64-year-old male with a history of hypertension presented with worsening diarrhea and 25-pound weight loss over the preceding three months. Prior screening colonoscopy was unremarkable, and the patient failed conservative management. On presentation, the patient had orthostatic hypotension associated with prerenal azotemia for which olmesartan (40 mg/day was held. Initial workup for chronic diarrhea was essentially unremarkable. Then, EGD was performed with small bowel biopsy, which showed a moderate villous blunting and an intraepithelial lymphocyte infiltration. Celiac disease was excluded by negative conventional serology tests and the absence of clinical response to a gluten-free diet. In the interim, diarrhea became resolving without any other interventions, and clinical response was achieved even with gluten-containing diet. Two months later, he achieved a complete resolution of diarrhea and regained 20-pound weight. Spruelike enteropathy is a clinical entity manifested by chronic diarrhea and intestinal villous atrophy. Spruelike enteropathy associated with olmesartan as a cause of drug-induced diarrhea is rare, and it has been reported only in a case series to date. This case highlighted the importance for clinicians to maintain a high index of suspicion for olmesartan as a precipitant of spruelike enteropathy.

    Previously, bovine viral diarrhea virus (BVDV) had been found in prolonged testicular infections following acute infection of immunocompetent bulls. The primary purpose of this research was to evaluate the production and maintenance of prolonged testicular infections after exposure to BVDV of seronegative bulls in varying circumstances. The secondary objective was to initiate assessment of the potential for transmission of BVDV via semen of bulls exhibiting a prolonged testicular infection. In total, 10 research trials were conducted. The first trial examined the duration of detectable virus in semen after intranasal inoculation of peri-pubertal bulls. The second to fifth trials examined the potential for prolonged testicular infections resulting from natural exposure of seronegative bulls to persistently infected heifers. In the last five trials, the potential for viral transmission from bulls exhibiting prolonged testicular infections to a small number of exposed animals (n=28) was evaluated. Results of this research demonstrated that prolonged testicular infections could result in detection of viral RNA in semen for 2.75 years with infectious virus grown from testicular tissue 12.5 months after viral exposure. A type 1b strain of BVDV caused prolonged testicular infection after natural exposure of seronegative bulls to a persistently infected heifer. However, transmission of BVDV to susceptible animals was not detected in the final five trials of this research. In conclusion, BVDV can persist in testicular tissue after acute infection for several years, but the potential for viral transmission from these prolonged testicular infections appears to be low.

  11. Bovine viral diarrhea (BVD: A review emphasizing on Iran perspective

    Mohammad Khezri

    2015-09-01

    Full Text Available Bovine viral diarrhea (BVD is one of the most important diseases of cattle responsible for major economic losses in dairy industries of Iran. So far, no nationwide program has been taken in Iran to control and eradicate the disease. Moreover, until now, no vaccination program has been practiced against BVD in Iran, although the disease is prevailing in the country. For effective controlling of BVD, it is necessary to cull the affected animals, and new entry of BVD in the farm should be prevented. Focusing on biosecurity in systematic control programs of BVD can also reduce the risks of introduction and spread of other epizootic and zoonotic diseases, thereby improving both cattle health and welfare in general. In this review paper, an overview on BVD emphasizing on Iran perspective has been discussed focusing on clinical manifestations of BVD, routes of transmission of BVD virus (BVDV, its diagnostic methods and possible prevention strategies.

    2012-09-01

    Full Text Available Abstract Background Noroviruses (NoVs are members of the family Caliciviridae and are emerging enteric pathogens of humans and animals. Some porcine NoVs are genetically similar to human strains and are classified into GII, like most epidemic human NoVs. So far, PoNoV have been exclusively detected in fecal samples of adult pig without clinical signs. Results Result showed that 2 of the 12 evaluated fecal samples were positive for PoNoVs, one of which was positive for PoNoV alone, and the other was coinfected with porcine circovirus and PoNoV. Phylogenetic and recombination analysis showed that the PoNoV positive alone strain was a recombinant new genotype strain. Experimental infection of miniature pigs with fecal suspensions confirmed that this strain can cause gastroenteritis in piglets. Conclusion This is the first report that recombinant new genotype PoNoV exised in pig herd of China, which cause diarrhea in pigs in nature condition. This find raised questions about the putative epidemiologic role of PoNoV.

    Full Text Available , (Received 21 Jun, 2008 ; Accepted 12 Nov, 2008 AbstractAccording to the statistics provided by the World Health Organization (WHO, about 80% of the world population nowadays uses herbal drugs for treatment of diseases. Natural products obtained from medicinal plants, serve as a great source for drug production and are the main basis of new drug compounds. Unicellular organisms (Protozoa are the cause of deaths and spread of diseases in various societies, especially in developing countries. There are anti-malaria herbal dugs produced from various medicinal plants, some of which are used for treatment of the disease and some under study. The first anti-malaria drug was quinine, produced from bark of the Cinchona tree. Recently, the drug artemisinin has been introduced by Chinese scientists for the treatment of malaria and is currently used extensively. Coetaneous leishmaniosis (salak is one of the endemic diseases in most parts of Iran. Common drugs used against leishmaniosis (such as glucantim, have severe side-effects and in 10 to 25% of cases, there is a recurrence of the disease. Emetine is one of the drugs obtained from a root of the plant Ipecac, which is used for treatment of the disease sub-cutaneously. Giardiasis is an acute protozoan infection usually with no clinical symptoms, however, may appear as acute or chronic diarrhea. According to the announcement of WHO, more than 2/3 of the world’s population is infected with intestinal parasites and the prevalence of giardia is higher than other intestinal parasites. Herbal drugs, such as wild garlic, eucalyptus and thyme, are some of the major plants which can annihilate the giarda cysts. Annually, 75000 to 100000 people die of amebiasis (dysentery worldwide. Due to the motility of the organism, it causes sever pathological changes and sometimes colon ulcers, and if entered into the blood stream, it may appear as liver or brain abscess.

  14. Predictors of rational management of diarrhea in an endemic setting: observation from India.

    Tanmay Mahapatra

    Full Text Available Decades after the establishment of clear guidelines for management, mostly due to irrational approach, diarrhea is still a major concern in the developing world, including India. The scenario is even worse in urban slums owing to poor health-seeking and socio-environmental vulnerability. Determining the distribution of rational diarrhea management by practitioners and identification of its important predictors seemed urgent to minimize the potential for antibiotic resistance, diarrhea-related mortality and morbidity in these areas.Between May 2011 and January 2012, 264 consenting, randomly selected qualified and non-qualified practitioners (including pharmacists were interviewed in the slums of Kolkata, a populous city in eastern India, regarding their characteristics, diarrhea-related knowledge (overall and in six separate domains: signs/symptoms, occurrence/spread, management, prevention/control, cholera and ORS, prescribed antibiotics, intravenous fluid (IVF and laboratory investigations. Rationality was established based on standard textbooks.Among participants, 53.03% had no medical qualifications, 6.06% were attached to Governmental hospitals, 19.32% had best knowledge regarding diarrhea. While treating diarrhea, 7.20%, 17.80% and 20.08% respectively advised antibiotics, IVF and laboratory tests rationally. Logistic regression revealed that qualified and Governmental-sector practitioners managed diarrhea more rationally.

  19. Adaptation cost of diarrhea and malaria in 2030 for India

    Sandhya K Ramakrishnan

    2011-01-01

    Full Text Available Background : Climate change is significant and an emerging threat to public health. The climate change-related health consequences of diarrheal diseases and malaria are projected to pose the largest risks to future populations. This study provides an initial estimate of the cost of intervention to cope with the health impacts of climate change in 2030 on diarrhea and malaria for India. Materials and Methods : The costs of treating diarrheal diseases and malaria in 2030 were estimated under three climate scenarios using: (1 the current numbers of cases; (2 the projected relative risks of these diseases in 2030; and (3 current treatment costs. The analysis assumed that the number of annual cases and costs of treatment would remain constant. There was limited consideration for population growth and socioeconomic development. Results : Underscenario assuming emissions reduction resulting in stabilization at 750 ppm CO 2 equivalent in 2210, the costs of treating diarrheal diseases and malaria were estimated to be between Rs. 3648 lakhs and Rs. 7787 lakhs. The Mitigation scenario results in fewer cases and lower investment needs than the BAU scenario. For the middle scenario, the annual needs are about Rs. 1036 lakhs per year, lower from Rs. 4684 lakhs down to Rs. 3648 lakhs. Should the high scenario occur, the annual investment needs are about Rs. 3901 lakhs lower from the BAU to the Mitigation scenario. Conclusion : The adaptation and mitigation can reduce sensitivity to climate change. The case for making public expenditures is strong on economic and moral grounds because the costs without interventions are much higher if we consider the relative risk of these diseases.

    Noroviruses are a major cause of acute gastroenteritis, but no vaccines or therapeutic drugs are available. Llama-derived single chain antibody fragments (also called VHH) are small, recombinant monoclonal antibodies of 15 kDa with several advantages over conventional antibodies. The aim of this study was to generate recombinant monoclonal VHH specific for the two major norovirus (NoV) genogroups (GI and GII) in order to investigate their potential as immunotherapy for the treatment of NoV diarrhea. To accomplish this objective, two llamas were immunized with either GI.1 (Norwalk-1968) or GII.4 (MD2004) VLPs. After immunization, peripheral blood lymphocytes were collected and used to generate two VHH libraries. Using phage display technology, 10 VHH clones specific for GI.1, and 8 specific for GII.4 were selected for further characterization. All VHH recognized conformational epitopes in the P domain of the immunizing VP1 capsid protein, with the exception of one GII.4 VHH that recognized a linear P domain epitope. The GI.1 VHHs were highly specific for the immunizing GI.1 genotype, with only one VHH cross-reacting with GI.3 genotype. The GII.4 VHHs reacted with the immunizing GII.4 strain and showed a varying reactivity profile among different GII genotypes. One VHH specific for GI.1 and three specific for GII.4 could block the binding of homologous VLPs to synthetic HBGA carbohydrates, saliva, and pig gastric mucin, and in addition, could inhibit the hemagglutination of red blood cells by homologous VLPs. The ability of Nov-specific VHHs to perform well in these surrogate neutralization assays supports their further development as immunotherapy for NoV treatment and immunoprophylaxis. PMID:26267898

    2014-07-01

    Full Text Available Background In cases of acute diarrhea, it is difficult to distinguish between bacterial and non-bacterial causes. Increased fecal calprotectin (f-CP level is a marker of neutrophil migration in the intestinal lumen and is associated with intestinal inflammation. Previous studies reported an increase in f-CP levels in children with acute diarrhea, which is caused by bacteria, but only few have studied the relationship between intestinal pathogens with f-CP levels in acute diarrhea. Objective To assess for a correlation between gut pathogens and fecal calprotectin levels in children with acute diarrhea. Methods We conducted a cross-sectional study between July to November 2012 on children aged 1-5 years with acute diarrhea, and underwent routine blood tests, stool microscopy, f-CP tests, and stool cultures. We used a simple linear regression and correlation analysis with a significance level of P<0.05. Results Forty-two children enrolled in this study. The mean age of subjects was 2.27 (SD 1.34 years. Their mean f-CP level was 93.88 (SD 14.68 μg/g. On microscopic stool examination, 26 patients (61.9% had positive leukocytes, 1 had Ancylostoma duodenale, 1 had Ascaris lumbricoides, and 2 had Blastocystis hominis. Positive stool cultures were found in 14 children (33.3% with acute diarrhea. There was a significant positive correlation between gut pathogens and f-CP levels (r=0.605; P<0.0001. Conclusion In young children with acute diarrhea, the average f-CP levels are higher in those with positive intestinal pathogens. [Paediatr Indones. 2014;54:193-7.].

  13. Addressing concrete cracking in NPPs

    The phenomenon of concrete cracking is one of the most frequently encountered deterioration at NPPs as it has been shown by a wide Survey of NPPs performed by IAEA in 1994-95 It can be due to a multitude of causes such as the normal ageing process (shrinkage, creep, prestressing force loss) as well as exposure to the environment (temperature variation, moisture, freeze/thaw, etc) The above mentioned Survey has also shown that in 64% of cases, no action was taken or required. It became also obvious that there is a lack of guidance as when remedial actions are needed. The paper describes, with the help of a Flow Chart, the various stages to be considered, from the first step of identification of cracks, to the definition of causes, evaluation of extent of damage, evaluation of effect/implications (safety, reliability), to the final step of deciding if repair action is required. Finally, based upon a wide literature survey the paper proposes in a Chart format, Criteria for addressing concrete cracks in NPPs., when taking in considerations all these factors. This paper discusses the process which should lead to the selection of an effective repair method and proposes, based upon worldwide standards and literature, criteria which should lead to the decision whether to repair or not concrete cracks, after the cracks have been identified and evaluated, addressing the entire range of aspects involved.

    Verotoxin producing Escherichia coli, in particular serotype O157:H7, have been implicated as an important cause of acute gastroenteritis in children. This study was undertaken to determine if E.coli O157:H7 is an important cause of acute gastroenteritis in children in metropolitan Sydney. During th

  15. Therapeutic value of zinc supplementation in acute and persistent diarrhea: a systematic review.

    Archana Patel

    Full Text Available BACKGROUND: For over a decade, the importance of zinc in the treatment of acute and persistent diarrhea has been recognized. In spite of recently published reviews, there remain several unanswered questions about the role of zinc supplementation in childhood diarrhea in the developing countries. Our study aimed to assess the therapeutic benefits of zinc supplementation in the treatment of acute or persistent diarrhea in children, and to examine the causes of any heterogeneity of response to zinc supplementation. METHODS AND FINDINGS: EMBASE, MEDLINE and CINAHL databases were searched for published reviews and meta-analyses on the use of zinc supplementation for the prevention and treatment of childhood diarrhea. Additional RCTs published following the meta-analyses were also sought. The reviews and published RCTs were qualitatively mapped followed by updated random-effects meta-analyses, subgroup meta-analyses and meta-regression to quantify and characterize the role of zinc supplementation with diarrhea-related outcomes. We found that although there was evidence to support the use of zinc to treat diarrhea in children, there was significant unexplained heterogeneity across the studies for the effect of zinc supplementation in reducing important diarrhea outcomes. Zinc supplementation reduced the mean duration of diarrhea by 19.7% but had no effect on stool frequency or stool output, and increased the risk of vomiting. Our subgroup meta-analyses and meta-regression showed that age, stunting, breast-feeding and baseline zinc levels could not explain the heterogeneity associated with differential reduction in the mean diarrheal duration. However, the baseline zinc levels may not be representative of the existing zinc deficiency state. CONCLUSIONS: Understanding the predictors of zinc efficacy including the role of diarrheal disease etiology on the response to zinc would help to identify the populations most likely to benefit from supplementation

  16. Calcium-sensing receptor: A new target for therapy of diarrhea.

    Cheng, Sam Xianjun

    2016-03-01

    Management of acute diarrhea remains a global challenge, particularly in resource-limiting countries. Oral rehydration solution (ORS), a passive rehydrating therapy developed approximately 40 years ago, remains the mainstay treatment. Although ORS is effective for hydration, since it does not inhibit enterotoxin-mediated excessive secretion, reduced absorption and compromised barrier function - the primary mechanisms of diarrhea, ORS does not offer a rapid relief of diarrhea symptom. There are a few alternative therapies available, yet the use of these drugs is limited by their expense, lack of availability and/or safety concerns. Novel anti-diarrheal therapeutic approaches, particularly those simple affordable therapies, are needed. This article explores intestinal calcium-sensing receptor (CaSR), a newly uncovered target for therapy of diarrhea. Unlike others, targeting this host antidiarrheal receptor system appears "all-inclusive": it is anti-secretory, pro-absorptive, anti-motility, and anti-inflammatory. Thus, activating CaSR reverses changes of both secretory and inflammatory diarrheas. Considering its unique property of using simple nutrients such as calcium, polyamines, and certain amino acids/oligopeptides as activators, it is possible that through targeting of CaSR with a combination of specific nutrients, novel oral rehydrating solutions that are inexpensive and practical to use in all countries may be developed.

    2003-01-01

    Full Text Available OBJECTIVE: To quantify the influence of the type of child-care on the occurrence of acute diarrhea with special emphasis on the effect of children grouping during care. METHODS: From October 1998 to January 1999 292 children, aged 24 to 36 months, recruited using a previously assembled cohort of newborns, were evaluated. Information on the type of care and occurrence of diarrhea in the previous year was obtained from parents by telephone interview. The X² and Kruskal-Wallis tests were used to compare proportions and quantitative variables, respectively. The risk of diarrhea was estimated through the calculation of incident odds ratios (OR and their respective 95% confidence intervals (95% CI, crude and adjusted by unconditional logistic regression. RESULTS: Using as reference category children cared individually at home, the adjusted ORs for diarrhea occurrence were 3.18, 95% CI [1.49, 6.77] for children cared in group at home, 2.28, 95% CI [0.92, 5.67] for children cared in group in day-care homes and 2.54, 95% CI [1.21, 5.33] for children cared in day-care centers. Children that changed from any other type of child-care setting to child-care centers in the year preceding the study showed a risk even higher (OR 7.65, 95% CI [3.25, 18.02]. CONCLUSIONS: Group care increases the risk of acute diarrhea whatsoever the specific setting.

    Congenital glucose-galactose malabsorption (CGGM) is a rare autosomal recessive disorder, which presents as a protracted diarrhea in early neonatal life. We describe the clinical history, diagnostic evaluation, and management of 7 children with CGGM in western France. There were 4 girls and 3 boys from 5 families, born between 1984 and 2010. The principal complaint was a neonatal onset of watery and acidic severe diarrhea complicated by hypertonic dehydration. The diarrhea stopped with fasting. In 2 cases, the family history supported the diagnosis. In the other cases, elimination of glucose and galactose (lactose) from the diet resulted in the complete resolution of diarrhea symptoms. In 2 cases, the H2 breath tests were positive. In 2 cases, the HGPO or oral glucose tolerance test (OGTT) demonstrated an abnormal curve with glucose and a normal curve with fructose. DNA sequencing was not used. When glucose and galactose were eliminated from the diet, the infants had normal growth and development. In conclusion, CGGM is a rare etiology of neonatal diarrhea; however, the diagnosis is easy to make and the prognosis is excellent. PMID:23107089

    Ulcerative colitis (UC) belongs to inflammatory bowel disorders, a group of gastrointestinal disorders that can produce serious recurring diarrhea in affected patients. The mechanism for UC- and inflammatory bowel disorder-associated diarrhea is not well understood. The cystic fibrosis transmembrane-conductance regulator (CFTR) chloride channel plays an important role in fluid and water transport across the intestinal mucosa. CFTR channel function is regulated in a compartmentalized manner through the formation of CFTR-containing macromolecular complexes at the plasma membrane. In this study, we demonstrate the involvement of a novel macromolecular signaling pathway that causes diarrhea in UC. We found that a nitric oxide-producing enzyme, inducible nitric oxide synthase (iNOS), is overexpressed under the plasma membrane and generates compartmentalized cGMP in gut epithelia in UC. The scaffolding protein Na(+)/H(+) exchanger regulatory factor 2 (NHERF2) bridges iNOS with CFTR, forming CFTR-NHERF2-iNOS macromolecular complexes that potentiate CFTR channel function via the nitric oxide-cGMP pathway under inflammatory conditions both in vitro and in vivo. Potential disruption of these complexes in Nherf2(-/-) mice may render them more resistant to CFTR-mediated secretory diarrhea than Nherf2(+/+) mice in murine colitis models. Our study provides insight into the mechanism of pathophysiologic occurrence of diarrhea in UC and suggests that targeting CFTR and CFTR-containing macromolecular complexes will ameliorate diarrheal symptoms and improve conditions associated with inflammatory bowel disorders.

  1. Influence of Zinc Supplementation in Acute Diarrhea Differs by the Isolated Organism

    Archana B. Patel

    2010-01-01

    Full Text Available Zinc supplementation is recommended in all acute diarrheas in children from developing countries. We aimed to assess whether zinc supplementation would be equally effective against all the common organisms associated with acute diarrheas. We used data on 801 children with acute diarrhea recruited in a randomized, double blind controlled trial (ISRCTN85071383 of zinc and copper supplementation. Using prespecified subgroup analyses, multidimensionality reduction analyses, tests of heterogeneity, and stepwise logistic regression for tests of interactions, we found that the influence of zinc on the risk of diarrhea for more than 3 days depended on the isolated organism—beneficial in Klebsiella, neutral in Esherichia coli and parasitic infections, and detrimental in rotavirus coinfections. Although we found similar results for the outcome of high stool volume, the results did not reach statistical significance. Our findings suggest that the current strategy of zinc supplementation in all cases of acute diarrheas in children may need appropriate fine tuning to optimize the therapeutic benefit based on the causative organism, but further studies need to confirm and extend our findings.

    BACKGROUND Celiac disease is a hypersensitivity enteropathy that can have various presentations in adults. Rarely, patients can present with severe lab abnormalities, dehydration and weight loss caused by celiac disease - a celiac crisis. CASE REPORT A 46-year-old male with a past medical history significant for diabetes mellitus, type 2 (DM2) and recently treated Bell's Palsy presented to the emergency room complaining of weakness, diarrhea and lightheadedness. On presentation, the patient had a systolic blood pressure (SBP) of 60 mm Hg and a lactic acidosis with pH of 7.28. Infectious etiologies of diarrhea were ruled out. The patient had an EGD which showed erythema of the duodenal bulb. Serum anti-gliadin and anti-TTG IgA were both elevated suggesting Celiac disease. Biopsies showed histopathology consistent with celiac disease. The patient's diarrhea resolved after initiation of a gluten free diet. He gained 25 kilograms after discharge and did not require further hospitalizations for diarrhea. CONCLUSIONS Celiac crisis is a very rare presentation of celiac disease in adults but nonetheless should be considered in patients with marked metabolic derangements in the setting of osmotic diarrhea. Treatment consists of a gluten free diet and may require management with steroids and total parenteral nutrition (TPN). PMID:27492679

    Handwashing practices among caretakers of case and control children Soap or detergent ownership was common, yet 48% of case and 47.7% of control caretakers also kept ashes for handwashing, including 36.8% of the wealthiest households. Soap, detergent, and ash were used for multiple hygiene purposes and were kept together at handwashing areas. Caretakers preferred soap for handwashing, but frequently relied on ash, or a detergent/ash mixture, as a low-cost alternative. Moderate-to-severe diarrhea was equally likely for children of caretakers who kept soap versus those who kept ash (matched OR = 0.91; 0.62-1.32). Contact with ash and water reduced concentrations of bacterial enteropathogens, without mechanical scrubbing. Thus, washing hands with ash is a prevalent behavior in Mirzapur and may help diminish transmission of diarrheal pathogens to children. PMID:24778193

    Full Text Available Acute kidney injury (AKI is becoming more prevalent among hospitalized children, its etiologies are shifting, and new treatment modalities are evolving; however, diarrhea-associated hemolytic uremic syndrome (D+HUS remains the most common primary disease causing AKI in young children. Little has been published about acute renal replacement therapy (ARRT and its challenges in this population. We describe our single center's experience managing 134 pediatric patients with D+HUS out of whom 58 (43% required ARRT over the past 16 years. In our cohort, all but one patient were started on peritoneal dialysis (PD. Most patients, 47 (81%, received acute PD on a pediatric inpatient ward. The most common recorded complications in our cohort were peritoneal fluid leaks 13 (22%, peritonitis 11 (20%, and catheter malfunction 5 (9%. Nine patients (16% needed surgical revision of their PD catheters. There were no bleeding events related to PD despite a mean platelets count of 40.9 (±23.5 × 103/mm3 and rare use of platelets infusions. Despite its methodological limitations, this paper adds to the limited body of evidence supporting the use of acute PD as the primary ARRT modality in children with D+HUS.

  7. Addressing viral resistance through vaccines

    Laughlin, Catherine; Schleif, Amanda; Heilman, Carole A

    2015-01-01

    Antimicrobial resistance is a serious healthcare concern affecting millions of people around the world. Antiviral resistance has been viewed as a lesser threat than antibiotic resistance, but it is important to consider approaches to address this growing issue. While vaccination is a logical strategy, and has been shown to be successful many times over, next generation viral vaccines with a specific goal of curbing antiviral resistance will need to clear several hurdles including vaccine design, evaluation and implementation. This article suggests that a new model of vaccination may need to be considered: rather than focusing on public health, this model would primarily target sectors of the population who are at high risk for complications from certain infections.

    Celiac disease (CD) is common in Caucasians, but thought to be rare in Asians. Our aim was to determine the prevalence of CD in Chinese patients with chronic diarrhea predominant irritable bowel syndrome (IBS-D).From July 2010 to August 2012, 395 adult patients with IBS-D and 363 age and sex-matched healthy controls were recruited in Zhongnan Hospital of Wuhan University and Xiaogan Central Hospital in Hubei province, central China. Patients with IBS-D were diagnosed according to the Rome III criteria. Serum Immunoglobulin (IgA/IgG) anti-human tissue transglutaminase (anti-htTG)-deamidated gliadin peptide (DGP) antibodies were measured in a single ELISA (QUANTA Lite h-tTG/DGP Screen). Upper endoscopy with duodenal biopsies and HLA-DQA1 and HLA-DQB1 genotyping were performed in seropositive subjects and a gluten-free diet was prescribed.Seven IBS-D patients (7/395, 1.77%) and 2 healthy controls (2/363, 0.55%), were positive for anti-htTG/DGP antibodies. Of these 9 cases, 1 was lost to follow-up, 3 were suspected to have CD and 5 were eventually diagnosed as CD with intestinal histological lesions classified as Marsh Type II in 2 and Type III in 3. Of these 5 diagnosed CD patients, 4 (4/395, 1.01%) were from the IBS-D group and 1 (1/363, 0.28%) from the healthy control had asymptomatic CD. Two Type III CD patients with relatively high titers in the serologic assay were homozygous and heterozygous for haplotype HLA-DQA1*03-DQB1*03:03 (HLA-DQ9.3), respectively.In the present study, CD was present in 1.01% of patients with IBS-D and in 0.28% of the control group. We like to suggest that the haplotype HLA-DQA1*03-DQB1*03:03 (HLA-DQ9.3), which is common in Chinese, is a new susceptibility factor for CD in China. Larger screening and genetic studies are needed in the Chinese population of different regions. PMID:26496305

    The main objective of this study was to investigate the epidemiology, drug resistance and β-lactamase genotype distribution of enteropathogenic Escherichia coli (EPEC) isolated from pediatric patients with diarrhea in southern China. The prevalence of EPEC in children with diarrhea was 3.53%. The commonest serotypes were O55:K59 and O126:K71, and the typical EPEC were more prevalent than atypical EPEC (51 vs 7). Isolates from this region were most commonly found to be resistant to ampicillin and cotrimoxazole, followed by chloramphenicol, ceftriaxone, and ceftazidime. More than 96% of the strains were susceptible to cefoperazone/sulbactam and imipenem. The most common β-lactamase genotypes identified in 58 strains were blaCTX-M-1 (60.3%), blaTEM (56.9%), blaCTX-M-9 (27.6%), and blaSHV (15.5%). Among 58 isolates, 22 strains were found to harbor one β-lactamase gene, and the proportions of resistance to ampicillin, cotrimoxazole, chloramphenicol, ceftriaxone, and ceftazidime, were 81.8%, 63.6%, 40.9%, 18.2%, and 9.1%, respectively. A further 30 strains carrying multiple β-lactamase genes had increased resistance to the above antimicrobial agents (100%, 83.3%, 70.0%, 60.0%, and 30.0%, respectively). In contrast, antibiotic resistance in the last 6 strains without a detectable β-lactamase gene was substantially reduced. Drug resistance may be associated with the β-lactamase gene number, with a greater the number of β-lactamase genes resulting in higher antibiotic resistance. PMID:25672408

    Full Text Available Genetic typing of bovine viral diarrhea virus (BVDV has distinguished BVDV-1 and BVDV-2 species and an emerging putative third species (HoBi-like virus, recently detected in southern Italy, signaling the occurrence of natural infection in Europe. Recognizing the need to update the data on BVDV genetic variability in Italy for mounting local and European alerts, a wide collection of 5′ UTR sequences (n = 371 was selected to identify the frequency of genotypes and subtypes at the herd level. BVDV-1 had the highest frequency, followed by sporadic BVDV-2. No novel HoBi-like viruses were identified. Four distribution patterns of BVDV-1 subtypes were observed: highly prevalent subtypes with a wide temporal-spatial distribution (1b and 1e, low prevalent subtypes with a widespread geographic distribution (1a, 1d, 1g, 1h, and 1k or a restricted geographic distribution (1f, and sporadic subtypes detected only in single herds (1c, 1j, and 1l. BVDV-1c, k, and l are reported for the first time in Italy. A unique genetic variant was detected in the majority of herds, but cocirculation of genetic variants was also observed. Northern Italy ranked first for BVDV introduction, prevalence, and dispersion. Nevertheless, the presence of sporadic variants in other restricted areas suggests the risk of different routes of BVDV introduction.

    Full Text Available Background: Diarrheal diseases in children are a major public health concern in developing countries. Diarrheal infection spreads through contaminated food or drinking-water, or from person-to-person as a result of poor hygiene. This study was conducted to investigate the incidence of different microorganisms associated with diarrhea in infants and primary school children and their relation to sex and age in Zakho city, Kurdistan region, Iraq. Methods: During the period from September 2013 to May 2014, 600 diarrheic samples were collected from both sexes and different ages (4-8 years (65.38 and 64.07%, while parasites were among >6-10 years (64.67 and 60.11%. High viral prevalence were recorded among ages <2 to 6 years with the peak among <2 years (40.54%. Conclusions: From this study we conclude that about 57% of diarrheal cases were associated with bacteria, parasites, and viruses with E. coli, E. histolytica, G. lamblia and rotavirus as leading microorganisms. The mixed prevalence with two or more microorganisms was documented in 179 (37.36% out of 479 positive samples and the rate of microbial prevalence was found to be gender and age dependent.

  15. Imipenem-induced clostridium difficile diarrhea in a patient with chronic renal failure

    R Enríquez

    2011-01-01

    Full Text Available An 80-year-old man was diagnosed to have pneumonia and advanced chronic kidney disease. He presented with anuria and hemodialysis, by temporary femoral catheter, was initiated. He was empirically treated with imipenem/cilastatin 500 mg/24 h after hemodialysis. After 10 days of antibiotic intake, he developed severe diarrhea. Diagnosis of Clostridium difficile (CD-associated diarrhea was confirmed by detection of the toxins A and B in his stool. Imipenem therapy was discontinued; Vancomycin 500 mg orally every 6 h and 1000 mg per rectum every day was added. After two weeks of this treatment, the patient reported complete resolution of the diarrhea and stool samples were negative for Clostridium toxin. In this case, the most possible cause of CD colitis was considered to be imipenem because of the temporal relationship between exposure to the drug and onset of symptoms.

  17. Management of childhood diarrhea and use of oral rehydration salts in a suburban West African community

    Sodemann, Morten; Jakobsen, M S; Mølbak, Kare;

    1999-01-01

    In a household survey in Guinea-Bissau, 319 episodes of diarrhea in children were followed by interviews every second day with the aim of investigating perceived morbidity and subsequent actions taken. The majority of the mothers had good knowledge of oral rehydration salts (ORS). However, only 58......% of the episodes were treated with ORS and the amount given was insufficient. Mothers with no knowledge of ORS did not use it during the observed attack of diarrhea regardless of contact with a health center, which suggests that maternal knowledge is an important determinant of whether health...... personnel provide ORS. Children with diarrhea considered to be caused by teething were less likely to receive ORS in the acute phase (risk ratio = 0.6, 95% confidence interval [CI] = 0.5-0.9). Univariate analyses showed that the use of ORS was related to number of reported symptoms, the mother being the...

  19. Application of qPCR assays for diagnosing causes of viral mink diarrhea. Preliminary results

    Hartby, Christina Marie; Kvisgaard, Lise Kirstine; Larsen, Lars Erik;

    ). Diarrhea in mink can be caused by infectious agents (virus, bacteria and parasites) and food-related/multifactorial conditions. Known enteric viral infections are mink enteritis virus (MEV) and mink astrovirus. Coronaviruses and caliciviruses have also been implicated as potential causes or contributors to...... diarrhea in mink. Rotavirus is poorly described in mink, but has previously been demonstrated in feces from mink pups with and without clinical signs (Jorgensen et al. 1996). The pathogenicity of these viruses could be related to viral load, virulence and the age of the mink. Therefore, there is a need for...... a quantitative diagnostic approach. We have developed new or adapted previously published real-time PCR/RT-PCR assays for MEV, astrovirus, rota- and coronavirus diagnostics. The technical test validation was initially carried out on archived diarrhea samples from diagnosed positive animals and on...

    2015-09-01

    Diarrhea causes significant morbidity and mortality in Indian children under 5 years of age. Flies carry enteric pathogens and may mediate foodborne infections. In this study, we characterized fly densities as a determinant of infectious diarrhea in a longitudinal cohort of 160 urban and 80 rural households with 1,274 individuals (27% under 5 years of age) in Vellore, India. Household questionnaires on living conditions were completed at enrollment. Fly abundance was measured during the wet and dry seasons using fly ribbons placed in kitchens. PCRs for enteric bacteria, viruses, and protozoa were performed on 60 fly samples. Forty-three (72%) fly samples were positive for the following pathogens: norovirus (50%), Salmonella spp. (46.7%), rotavirus (6.7%), and Escherichia coli (6.7%). Ninety-one episodes of diarrhea occurred (89% in children under 5 years of age). Stool pathogens isolated in 24 of 77 (31%) samples included E. coli, Shigella spp., Vibrio spp., Giardia, Cryptosporidium, and rotavirus. Multivariate log-linear models were used to explore the relationships between diarrhea and fly densities, controlling for demographics, hygiene, and human-animal interactions. Fly abundance was 6 times higher in rural than urban sites (P < 0.0001). Disposal of garbage close to homes and rural living were significant risk factors for high fly densities. The presence of latrines was protective against high fly densities and diarrhea. The adjusted relative risks of diarrheal episodes and duration of diarrhea, associated with fly density at the 75th percentile, were 1.18 (95% confidence interval [CI], 1.03 to 1.34) and 1.15 (95% CI, 1.02 to 1.29), respectively. Flies harbored enteric pathogens, including norovirus, a poorly documented pathogen on flies. PMID:26116684

  3. How do the rotavirus NSP4 and bacterial enterotoxins lead differently to diarrhea?

    Vasseur Monique

    2007-03-01

    Full Text Available Abstract Rotavirus is the major cause of infantile gastroenteritis and each year causes 611 000 deaths worldwide. The virus infects the mature enterocytes of the villus tip of the small intestine and induces a watery diarrhea. Diarrhea can occur with no visible tissue damage and, conversely, the histological lesions can be asymptomatic. Rotavirus impairs activities of intestinal disaccharidases and Na+-solute symports coupled with water transport. Maldigestion of carbohydrates and their accumulation in the intestinal lumen as well as malabsorption of nutrients and a concomitant inhibition of water reabsorption can lead to a malabsorption component of diarrhea. Since the discovery of the NSP4 enterotoxin, diverse hypotheses have been proposed in favor of an additional secretion component in the pathogenesis of diarrhea. Rotavirus induces a moderate net chloride secretion at the onset of diarrhea, but the mechanisms appear to be quite different from those used by bacterial enterotoxins that cause pure secretory diarrhea. Rotavirus failed to stimulate Cl- secretion in crypt, whereas it stimulated Cl- reabsorption in villi, questioning, therefore, the origin of net Cl- secretion. A solution to this riddle was that intestinal villi do in fact secrete chloride as a result of rotavirus infection. Also, the overall chloride secretory response is regulated by a phospholipase C-dependent calcium signaling pathway induced by NSP4. However, the overall response is weak, suggesting that NSP4 may exert both secretory and subsequent anti-secretory actions, as did carbachol, hence limiting Cl- secretion. All these characteristics provide the means to make the necessary functional distinction between viral NSP4 and bacterial enterotoxins.

  4. Gender: addressing a critical focus.

    Thornton, L; Wegner, M N

    1995-01-01

    The definition of gender was addressed at the Fourth World Conference on Women (Beijing, China). After extensive debate, the definition developed by the UN Population Fund in 1995 was adopted: "a set of qualities and behaviors expected from a female or male by society." The sustainability of family planning (FP) programs depends on acknowledgment of the role gender plays in contraceptive decision-making and use. For example, programs must consider the fact that women in many cultures do not make FP decisions without the consent of their spouse. AVSC is examining providers' gender-based ideas about clients and the effects of these views on the quality of reproductive health services. Questions such as how service providers can encourage joint responsibility for contraception without requiring spousal consent or how they can make men feel comfortable about using a male method in a society where FP is considered a woman's issue are being discussed. Also relevant is how service providers can discuss sexual matters openly with female clients in cultures that do not allow women to enjoy their sexuality. Another concern is the potential for physical violence to a client as a result of the provision of FP services. PMID:12294397

  5. Glucose-Galactose Malabsorption as a Rare Cause of Diarrhea in Newborn Period

    SH Rasooli

    2002-10-01

    Full Text Available Glucose-Galactose malabsorption is a rare genetic disorder caused by a defect in Glucose and Galactose transport across the intestinal brush border. It is characterized by neonatal onset of sever watery, acidic diarrhea. In the past, it usually resulted in death within the first weeks of life. Now that the disease has been identified, children recover if Glucose and Galactose are withdrawn from their diet. In this article we report on two interesting cases of the disease consisting of 1 male and 1 female newborn with sever watery diarrhea beginning in the first days of life. These patients survived with appropriate Glucose and Galactose free formula.

  6. Diarrhea associated with enterotoxigenic Clostridium perfringens in a red-footed tortoise (Geochelone carbonaria).

    Weese, J S; Staempfli, H R

    2000-06-01

    Enterotoxigenic Clostridium perfringens was associated with diarrhea in a 4-yr-old female captive-bred red-footed tortoise (Geochelone carbonaria). Diagnosis was based on bacterial culture, detection of C. perfringens enterotoxin in feces, and exclusion of commonly recognized pathogens. After treatment with metronidazole, normal feces were passed and C. perfringens enterotoxin was no longer detected in the feces. Although the role of C. perfringens cannot be determined definitively from this case, this pathogen should be considered in cases of diarrhea in tortoises and, perhaps, other reptiles. PMID:10982148

  9. Enteric bacterial pathogens in children with diarrhea in Niger: diversity and antimicrobial resistance.

    Céline Langendorf

    Full Text Available Although rotavirus is the leading cause of severe diarrhea among children in sub-Saharan Africa, better knowledge of circulating enteric pathogenic bacteria and their antimicrobial resistance is crucial for prevention and treatment strategies.As a part of rotavirus gastroenteritis surveillance in Maradi, Niger, we performed stool culture on a sub-population of children under 5 with moderate-to-severe diarrhea between April 2010 and March 2012. Campylobacter, Shigella and Salmonella were sought with conventional culture and biochemical methods. Shigella and Salmonella were serotyped by slide agglutination. Enteropathogenic Escherichia coli (EPEC were screened by slide agglutination with EPEC O-typing antisera and confirmed by detection of virulence genes. Antimicrobial susceptibility was determined by disk diffusion. We enrolled 4020 children, including 230 with bloody diarrhea. At least one pathogenic bacterium was found in 28.0% of children with watery diarrhea and 42.2% with bloody diarrhea. Mixed infections were found in 10.3% of children. EPEC, Salmonella and Campylobacter spp. were similarly frequent in children with watery diarrhea (11.1%, 9.2% and 11.4% respectively and Shigella spp. were the most frequent among children with bloody diarrhea (22.1%. The most frequent Shigella serogroup was S. flexneri (69/122, 56.5%. The most frequent Salmonella serotypes were Typhimurimum (71/355, 20.0%, Enteritidis (56/355, 15.8% and Corvallis (46/355, 13.0%. The majority of putative EPEC isolates was confirmed to be EPEC (90/111, 81.1%. More than half of all Enterobacteriaceae were resistant to amoxicillin and co-trimoxazole. Around 13% (46/360 Salmonella exhibited an extended-spectrum beta-lactamase phenotype.This study provides updated information on enteric bacteria diversity and antibiotic resistance in the Sahel region, where such data are scarce.

    Chronic diarrhea is one of the most frequent gastro-intestinal manifestations in acquired immunodeficiency syndrome (AIDS).Protozoa and nontuberculous mycobacteria (NTM) are opportunistic pathogens that can easily infect these patients.Among the NTM,Mycobacterium avium complex (MAC) is the most frequently observed pathogen in HIV-infected patients.However,NTMs other than MAC have not been reported as a gastrointestinal pathogen as yet.We present a case of chronic diarrhea in an AIDS patient in whom Mycobacterium ulcerans and cryptosporidium co-infection is evidenced from colonic tissue.

  11. On the role of serotonin and histamine in neurohumoral mechanisms of postirradiation diarrhea in rats

    In experiments with rats exposed to 200 Gy radiation it was shown that the diarrhea effect of serotonin under the effect of radiation is implemented via D- and M-type receptors, and that of histamine via H1 and H2 receptors. Serotonin and histamine, that were released under the effect of radiation from endocrine and mast cells of the digestive tract stimulated the propulsion activity of the intestine whereas histamine, in addition, inhibited the absorption process. It is suggested that serotonin and histamine antagonists should be used as means of preventing of radiation-induced diarrhea

    Indonesia still faces several challenges in the areas of water, sanitation, and hygiene (WASH). Diarrhea remains a major killer of children and it is important to understand the local diarrhea transmission pathways to prioritise appropriate WASH interventions to reduce diarrhea burden. This study used a cross-sectional data set from a recent national household survey (the 2012 Indonesia Demographic and Health Survey) to examine the associations between diarrhea in children aged less than 24 months with WASH interventions and population characteristics. Unsafe disposal of child feces was strongly associated with an increased odds of child diarrhea (OR: 1.46; 95% CI: 1.18-1.82, p = 0.001). However, other WASH practices were not found to be associated. The findings underline the dangers of unsafe disposal of child feces and highlight the need for strengthening the related policies and program strategies and their implementation. PMID:26978379

  2. Addressing verification challenges [International safeguards symposium on addressing verification challenges

    In his welcome address the Director General of the International Atomic Energy Agency (IAEA), Mr. M. ElBaradei, stated that safeguards activities are probably the most difficult task entrusted to an international organization and to determine all the details of a country's nuclear programme is a daunting challenge that raises a number of questions. There is an increase in nuclear power around the globe as a result of shortages of energy and concerns about energy independence and climate change. On the one hand, this is good, because without energy there is no hope for development on the other hand, however, it means that nuclear know-how and nuclear technology will continue to spread to more and more countries. There is also an increase in the number of countries interested in developing nuclear fuel cycle capabilities: sensitive fuel cycle activities, reprocessing and above all uranium enrichment. It even seems that some countries might be hedging their bets in order to have the know-how should they need to develop their own deterrence. Verifying enrichment or reprocessing facilities is quite difficult, and the so-called conversion time is extremely short. Thus, the IAEA is dealing with what is called 'virtual nuclear weapon States'. The IAEA has been talking for a number of years about the need to develop a new international or multinational approach to the fuel cycle in order to avoid a situation with nine nuclear weapon States and another 20 or 30 States having the capacity to develop nuclear weapons in a very short period of time. There is a need to remember that there is a linkage between nuclear disarmament and non-proliferation. Furthermore safeguards activities, though fundamentally technical in nature, are carried out in a political charged environment. The security dimension - that is, nuclear terrorism - also presents a new challenge, because State systems of accounting for and control of nuclear material are no longer simply tools for safeguards, but

We investigated the differences in clinical, epidemiological and spatial characteristics of the two Vibrio species in the urban slums of Kolkata, India. Methods The data of a cluster randomized cholera vaccine trial were used. We restricted the analysis to clusters assigned to placebo. Survival analysis of the time to the first episode was used to analyze risk factors for V. parahaemolyticus diarrhea or cholera. A spatial scan test was used to identify high risk areas for cholera and for V. parahaemolyticus diarrhea. Results In total, 54,519 people from the placebo clusters were assembled. The incidence of cholera (1.30/1000/year was significantly higher than that of V. parahaemolyticus diarrhea (0.63/1000/year. Cholera incidence was inversely related to age, whereas the risk of V. parahaemolyticus diarrhea was age-independent. The seasonality of diarrhea due to the two Vibrio species was similar. Cholera was distinguished by a higher frequency of severe dehydration, and V. parahaemolyticus diarrhea was by abdominal pain. Hindus and those who live in household not using boiled or treated water were more likely to have V. parahaemolyticus diarrhea. Young age, low socioeconomic status, and living closer to a project healthcare facility were associated with an increased risk for cholera. The high risk area for cholera differed from the high risk area for V. parahaemolyticus diarrhea. Conclusion We report coexistence of the two vibrios in the slums of Kolkata. The two etiologies of diarrhea had a similar seasonality but had distinguishing clinical features. The risk factors and the high risk areas for the two diseases differ from one another suggesting different modes of transmission of these two pathogens.

  5. An address geocoding solution for Chinese cities

    2006-10-01

    We introduce the challenges of address geocoding for Chinese cities and present a potential solution along with a prototype system that deal with these challenges by combining and extending current geocoding solutions developed for United States and Japan. The proposed solution starts by separating city addresses into "standard" addresses which meet a predefined address model and non-standard ones. The standard addresses are stored in a structured relational database in their normalized forms, while a selected portion of the non-standard addresses are stored as aliases to the standard addresses. An in-memory address index is then constructed from the address database and serves as the basis for real-time address matching. Test results were obtained from two trials conducted in the city Beijing. On average 80% matching rate were achieved. Possible improvements to the current design are also discussed.

    2013-02-01

    Social determinants of health have a profound impact on health status and the prevalence of health disparities in the United States. Significant improvements in national health indices are not possible without addressing social determinants of health. Drawing on their historical legacy as patient advocates, patient care expertise, and community focused education, nurses are ideally positioned to lead the nation in strategies to promote health equity. Nurses can embrace this new leadership role through the use of interdisciplinary collaboration, advocacy, political involvement, and community partnerships. PMID:23793135

    2015-09-01

    Full Text Available Background The incidence rate of acute diarrheal disease in children is a health indicator, and the estimation of these data can help guide public health policies. Objectives The aim of this study was to estimate the incidence and risk factors for acute diarrheal disease in children aged 0 - 1 year. Patients and Methods An observational prospective cohort study was conducted on 210 children recruited at Hospital Nossa Senhora da Conceicao, in Tubarao, state of Santa Catarina, Brazil. Children born between July and September 2012 were followed up for 12 months. The presence of three or more liquid or loose stools during a 24-hour period was considered acute diarrhea. The categories of variables evaluated were comprised of sociodemographic characteristics (per capita income, maternal education, maternal age, access to medical care [public or private], and housing and living conditions [sanitation and hygiene, water supply, daycare attendance, and domestic animal] and characteristics of the child (gender, birth weight, and breastfeeding. Results The incidence of acute diarrhea among the 0 - 1-year-old children was 26.7 cases per 1,000 children per month. Independent risk factors for the occurrence of diarrhea were maternal age under 20 years and health care services provided by the Brazilian National Health System (SUS. Conclusions The high incidence density of diarrhea among the children recruited in this study indicates the need for educational programs directed at people who are involved in this issue.

    M. Simadibrata

    2002-09-01

    Full Text Available The incidence of chronic diarrhea in Asia is between 0.8-1.0%. The diseases and abnormalities according to the location, which can cause chronic diarrhea, are divided into three locations: the small bowel, the large bowel and extraintestinal. The small bowel diseases include infectious and non-infectious diseases. The infectious diseases are bacterial infections, parasitic infections etc. The non-infectious diseases include of Crohn’s disease, Celiac sprue, NSAID enteropathy, lactose intolerance, benign tumor, carcinoid tumor, carcinoma, post surgery complications, laxative etc. The approaches to diagnosis include good anamnesis, careful physical examination, supporting laboratory tests, more specialized supporting examinations including X-ray of the colon, esophagogastroduodenum follow-through, enteroclysis, ileo-colonoscopy and endoscopy on the upper portion of the digestive tract including the small intestine with biopsy for histopathology examinations. The treatment for chronic diarrhea is divided into supportive and causal therapy. (Med J Indones 2002; 11: 179-89 Keywords: small bowel, chronic diarrhea, approaches to diagnosis, treatment
