    Diarrhoea and pneumonia are the leading infectious causes of childhood morbidity and mortality. We comprehensively reviewed the epidemiology of childhood diarrhoea and pneumonia in 2010-11 to inform the planning of integrated control programmes for both illnesses. We estimated that, in 2010, there were 1·731 billion episodes of diarrhoea (36 million of which progressed to severe episodes) and 120 million episodes of pneumonia (14 million of which progressed to severe episodes) in children younger than 5 years. We estimated that, in 2011, 700,000 episodes of diarrhoea and 1·3 million of pneumonia led to death. A high proportion of deaths occurs in the first 2 years of life in both diseases--72% for diarrhoea and 81% for pneumonia. The epidemiology of childhood diarrhoea and that of pneumonia overlap, which might be partly because of shared risk factors, such as undernutrition, suboptimum breastfeeding, and zinc deficiency. Rotavirus is the most common cause of vaccine-preventable severe diarrhoea (associated with 28% of cases), and Streptococcus pneumoniae (18·3%) of vaccine-preventable severe pneumonia. Morbidity and mortality from childhood pneumonia and diarrhoea are falling, but action is needed globally and at country level to accelerate the reduction.

    Background Solar drinking water disinfection (SODIS) is a low-cost, point-of-use water purification method that has been disseminated globally. Laboratory studies suggest that SODIS is highly efficacious in inactivating waterborne pathogens. Previous field studies provided limited evidence for its effectiveness in reducing diarrhoea. Methods and Findings We conducted a cluster-randomized controlled trial in 22 rural communities in Bolivia to evaluate the effect of SODIS in reducing diarrhoea among children under the age of 5 y. A local nongovernmental organisation conducted a standardised interactive SODIS-promotion campaign in 11 communities targeting households, communities, and primary schools. Mothers completed a daily child health diary for 1 y. Within the intervention arm 225 households (376 children) were trained to expose water-filled polyethyleneteraphtalate bottles to sunlight. Eleven communities (200 households, 349 children) served as a control. We recorded 166,971 person-days of observation during the trial representing 79.9% and 78.9% of the total possible person-days of child observation in intervention and control arms, respectively. Mean compliance with SODIS was 32.1%. The reported incidence rate of gastrointestinal illness in children in the intervention arm was 3.6 compared to 4.3 episodes/year at risk in the control arm. The relative rate of diarrhoea adjusted for intracluster correlation was 0.81 (95% confidence interval 0.59–1.12). The median length of diarrhoea was 3 d in both groups. Conclusions Despite an extensive SODIS promotion campaign we found only moderate compliance with the intervention and no strong evidence for a substantive reduction in diarrhoea among children. These results suggest that there is a need for better evidence of how the well-established laboratory efficacy of this home-based water treatment method translates into field effectiveness under various cultural settings and intervention intensities.

    Background Childhood diarrhoea remains a major public health problem responsible for the deaths of approximately 800 000 children annually, worldwide. The present study was undertaken to further define research priorities for the prevention and treatment of diarrhoea in low and middle income countries. We used the Child Health and Nutrition Research Initiative (CHNRI) process for defining research priorities. This provided a transparent, systematic method of obtaining the opinions of experts regarding research priorities in childhood diarrhoea. The present report describes the deliberations of a workshop that reviewed these research priorities by stakeholders including colleagues from: government agencies, academic institutions, major funding agencies and non–governmental organizations. Methods The workshop included 38 participants, divided into four groups to consider issues in the categories of description, delivery, development and discovery. Each group received 20 to 23 questions/research priorities previously identified by the CHNRI process. Deliberations and conclusions of each group were summarized in separate reports that were further discussed in a plenary session including all workshop participants. Results The reports of the working groups emphasized the following five key points: 1) A common theme was the need to substantially increase the use of oral rehydration salts (ORS) and zinc in the prevention and treatment of diarrhoea. There is a need for better definitions of those factors that supported and interfered with the use of these agents; 2) There is an urgent need to determine the long–term effects of chronic and recurrent bouts of diarrhoea on the physical and intellectual development of affected children; 3) Improvements in water, sanitation and hygiene facilities are critical steps required to reduce the incidence and severity of childhood diarrhoea; 4)Risk factors enhancing the susceptibility and clinical response to diarrhoea were

    In 1980, diarrhoea was the leading cause of child mortality, accounting for 4.6 million deaths annually. Efforts to control diarrhoea over the past decade have been based on multiple, potentially powerful interventions implemented more or less simultaneously. Oral rehydration therapy (ORT) was introduced in 1979 and rapidly became the cornerstone of programmes for the control of diarrhoeal diseases. We report on the strategy for controlling diarrhoea through case management, with special reference to ORT, and on the relationship between its implementation and reduced mortality. Population-based data on the coverage and quality of facility-based use of ORT are scarce, despite its potential importance in reducing mortality, especially for severe cases. ORT use rates during the 1980s are available for only a few countries. An improvement in the availability of data occurred in the mid-1990s. The study of time trends is hampered by the use of several different definitions of ORT. Nevertheless, the data show positive trends in diarrhoea management in most parts of the world. ORT is now given to the majority of children with diarrhoea. The annual number of deaths attributable to diarrhoea among children aged under 5 years fell from the estimated 4.6 million in 1980 to about 1.5 million today. Case studies in Brazil, Egypt, Mexico, and the Philippines confirm increases in the use of ORT which are concomitant with marked falls in mortality. In some countries, possible alternative explanations for the observed decline in mortality have been fairly confidently ruled out. Experience with ORT can provide useful guidance for child survival programmes. With adequate political will and financial support, cost-effective interventions other than that of immunization can be successfully delivered by national programmes. Furthermore, there are important lessons for evaluators. The population-based data needed to establish trends in health service delivery, outcomes and impact are not

    Global mortality in children younger than 5 years has fallen substantially in the past two decades from more than 12 million in 1990, to 6·9 million in 2011, but progress is inconsistent between countries. Pneumonia and diarrhoea are the two leading causes of death in this age group and have overlapping risk factors. Several interventions can effectively address these problems, but are not available to those in need. We systematically reviewed evidence showing the effectiveness of various potential preventive and therapeutic interventions against childhood diarrhoea and pneumonia, and relevant delivery strategies. We used the Lives Saved Tool model to assess the effect on mortality when these interventions are applied. We estimate that if implemented at present annual rates of increase in each of the 75 Countdown countries, these interventions and packages of care could save 54% of diarrhoea and 51% of pneumonia deaths by 2025 at a cost of US$3·8 billion. However, if coverage of these key evidence-based interventions were scaled up to at least 80%, and that for immunisations to at least 90%, 95% of diarrhoea and 67% of pneumonia deaths in children younger than 5 years could be eliminated by 2025 at a cost of $6·715 billion. New delivery platforms could promote equitable access and community platforms are important catalysts in this respect. Furthermore, several of these interventions could reduce morbidity and overall burden of disease, with possible benefits for developmental outcomes.

    To investigate the association between bacteriological drinking water quality and incidence of diarrhoea, we conducted a 1-year prospective study in the southern Punjab, Pakistan. Diarrhoea episodes, drinking water sources and drinking water quality were monitored weekly among children younger than 5 years in 200 households. We found no association between the incidence of childhood diarrhoea and the number of Escherichia coli in the drinking water sources (the public domain). A possible trend was seen relating the number of E. coli in the household storage containers (the domestic domain) and diarrhoea incidence, but this did not reach statistical significance. Faecal contamination levels in household water containers were generally high even when the source water was of good quality. Under conditions such as this, it is questionable whether public water treatment will have a significant impact on the incidence of endemic childhood diarrhoea.

    Diarrhoea remains the second leading cause of death in children under 5 years. Moreover, morbidity as a result of diarrhoea is high particularly in marginalised communities. Frequent bouts of diarrhoea have deleterious and irreversible effects on physical and cognitive development. Children are especially vulnerable given their inability to mount an active immune response to pathogen exposure. Biological limitations are exacerbated by the long-term effects of poverty, including reduced nutrition, poor hygiene and deprived home environments. Drawing from available literature, this paper uses syndemic theory to explore the role of adverse biosocial interactions in increasing the total disease burden of enteric infections in low-resources populations and assesses the limitations of recent global calls to action. The syndemic perspective describes situations in which adverse social conditions, including inequality, poverty and other forms of political and economic oppression, play a critical role in facilitating disease-disease interactions. Given the complex micro- and macro-nature of childhood diarrhoea, including interactions between pathogens, disease conditions and social environments, the syndemic perspective offers a way forward. While rarely the focus of health interventions, technologically advanced biomedical strategies are likely to be more effective if coupled with interventions that address the social conditions of disparity.

    Zinc supplementation reduces the severity, duration and recurrence of childhood acute diarrhoea. These beneficial effects of zinc in the treatment of diarrhoea led to the inclusion of a 10-14 days treatment regimen by the WHO/UNICEF. This study assessed the level of knowledge and use of zinc supplementation in the management of childhood diarrhoea among health care workers in public primary health facilities in Benin-City, Nigeria. Methodology: This cross-sectional study was carried out among the total population of health care providers in public primary health facilities in Benin-City. Data collection was done using a pre-tested, structured, self-administered questionnaire and data was analyzed using SPSS version 15.0. Results: A total of 168 health care workers participated in the study. Two-thirds of them were aware of zinc supplementation but specific knowledge of zinc supplementation in the management of childhood acute diarrhoea was poor. Thirty-five percent of them prescribed zinc when managing childhood diarrhoea and only 10% of these do so for every case of childhood diarrhoea. About 84.6% of them prescribed the correct dose of zinc while less than half of them prescribe it for the correct duration. All but one of them prescribed zinc in addition to ORS in line with the WHO guideline. Discussion: The study revealed a gap in the knowledge and practice of use of zinc supplementation in the management of childhood diarrhoea. It is recommended that nationwide campaigns should be embarked on to promote the use of zinc supplementation in the clinical management of childhood diarrhoea. PMID:22980153

    There is limited information on percent expenditure of household income due to childhood diarrhoea especially in rural Bangladesh. A total of 4205 children aged <5 years with acute diarrhoea were studied. Percent expenditure was calculated as total expenditure for the diarrhoeal episode divided by monthly family income, multiplied by 100. Overall median percent expenditure was 3·04 (range 0·01-94·35). For Vibrio cholerae it was 6·42 (range 0·52-82·85), for enterotoxigenic Escherichia coli 3·10 (range 0·22-91·87), for Shigella 3·17 (range 0·06-77·80), and for rotavirus 3·08 (range 0·06-48·00). In a multinomial logistic regression model, for the upper tertile of percent expenditure, significant higher odds were found for male sex, travelling a longer distance to reach hospital (⩾median of 4 miles), seeking care elsewhere before attending hospital, vomiting, higher frequency of purging (⩾10 times/day), some or severe dehydration and stunting. V. cholerae was the highest and rotavirus was the least responsible pathogen for percent expenditure of household income due to childhood diarrhoea.

    OBJECTIVE: To examine the effect of a new point-of-use treatment for drinking-water, a commercially developed flocculant-disinfectant, on the prevalence of diarrhoea in children. METHODS: We conducted a randomized controlled trial among 514 rural Guatemalan households, divided into 42 neighbourhood clusters, for 13 weeks, from 4 November 2002 through 31 January 2003. Clusters assigned to water treatment with the flocculant-disinfectant were compared with those using their usual water-handling practices. The longitudinal prevalence of diarrhoea was calculated as the proportion of total days with diarrhoea divided by the total number of days of observation. The prevalence of diarrhoea was compared using the Wilcoxon rank-sum test. FINDINGS: The 1702 people in households receiving the disinfectant had a prevalence of diarrhoea that was 40% lower than that among the 1699 people using standard water-handling practices (0.9% versus 1.5%; P = 0.001). In households using the flocculant-disinfectant, children < 1 year of age had a 39% lower prevalence of diarrhoea than those in households using their standard practices (3.7% versus 6.0%; P = 0.005). CONCLUSION: In settings where families rarely treat drinking-water, we introduced a novel flocculant-disinfectant that reduced the longitudinal prevalence of diarrhoea, especially among children aged < 1 year, among whom diarrhoea has been strongly associated with mortality. Successful introduction and use of this product could contribute to preventing diarrhoeal disease globally. PMID:16501712

    Chronic diarrhoea in children shows an age related spectrum. In infants and young children a major role is related to persistent intestinal infections, intolerance to specific nutrients such as cow's milk protein, and toddler's diarrhoea. In older children and adolescents, inflammatory bowel diseases are strongly increasing and nonspecific diarrhoea is also frequent. Coeliac disease is a major cause of diarrhoea throughout childhood. In neonates, congenital diarrhoea is a rare but severe syndrome that includes several highly complex diseases. In children, diagnosis should be based on noninvasive techniques. Endoscopy should be decided based on clinical criteria, but also driven by noninvasive tests to assess the digestive absorptive functions and intestinal inflammation. A stepwise approach may reduce the need of endoscopy, also in the light of its relatively limited diagnostic yield compared to adult patients. Treatment of chronic diarrhoea in children is also substantially different from what is generally done in adults and includes a major role for nutritional interventions. Therefore chronic diarrhoea in children is a complex age-specific disorder that requires an age-specific management that is in many aspects distinct from that in adults.

    The Government of India has identified oral rehydration therapy (ORT) promotion as a priority child survival strategy. Since two-thirds of mothers in India are illiterate, radio and television have been important vehicles for educating mothers about the need to increase a child's fluid intake and continue feeding during episodes of diarrhea, to use prepackaged oral rehydration salts (ORS) or a recommended home-made solution (RHS), and to recognize symptoms that require treatment at a health facility. The effects of exposure to electronic media messages about childhood diarrhea on mothers' knowledge and use of ORT were investigated through data from the 1992-93 National Family Health Survey. the data set included 38,161 women who gave birth in the 4 years preceding the survey and 4558 children born 1-47 months before the survey who were sick with diarrhea at any time during the 2 weeks before the interview. 43% of mothers were aware of ORS. Only 18% of infants received ORS and 19% were given RHS during the recent diarrhea episode; 69% received neither ORS or RHS. Moreover, children with diarrhea were twice as likely to receive decreased amounts of breast milk and other fluids than to be given increased amounts. The low use of ORS is especially alarming since 61% of children with diarrhea in the previous 2 weeks were taken to a health facility for treatment. 94% of these children were given antibiotics or other unnecessary drugs. Both knowledge and use of ORS were significantly higher among mothers with regular (weekly) exposure to electronic media, even after controls for potential confounding factors. These findings indicate a need to strengthen education programs in this area for both mothers and health care providers.

    Interventions to improve child health depend, at least implicitly, on changing maternal knowledge and behaviour and a reallocation of maternal time. There have been few studies, however, of the time cost involved in the adoption of new health technologies and even fewer that examine changes in maternal activities in response to child illness. The present study examines maternal daytime activities and investigates changes that occur when children are ill. We examine the impact of acute childhood diarrhoea episodes on the activity patterns of the mother/caretaker in this setting. The results show that mothers alter their usual activity patterns only slightly in response to acute diarrhoea episodes in their children. They continue to perform the same variety of activities as when the children are healthy, although they are more likely to perform them with the child 'carried' on their back. There is some indication that diarrhoea perceived to be more severe did result in the mother acting as caretaker more frequently. These findings have important implications for health interventions that depend on changing the amount of maternal or caretaker time spent for child health technologies, but the implications may vary depending on the reasons for the observed lack of changes in caretaker activities.

    The aim of this study was to investigate the role and clinical course of verotoxigenic Escherichia coli (VTEC) infections in children with acute diarrhoea from Argentina, the country with the highest worldwide incidence of haemolytic uraemic syndrome (HUS). To accomplish this objective, 437 samples from children up to 6 years old with acute diarrhoea were collected and processed. More than 60 % of the children studied presented watery or mucous diarrhoea without blood, and in 25.2 % of the cases the samples contained blood. In a first screening, a multiplex PCR was performed to detect the presence of the vt(1), vt(2), eae, ehxA and saa virulence genes. The strains were then isolated and analysed to characterize their serotypes, virulence genes, antibiotic susceptibility profiles and verotoxin (VT) production. Forty-four of the 437 samples (10.1 %) were positive for VTEC virulence genes. VTEC-infected patients presented different types of diarrhoea (27.3 % belonged to the non-bloody type). Several serotypes and virulence genotypes were found. Isolates belonged to the serotypes O157 : H7, O145 : H(-), O26 : H11, O121 : H19, O111 : H2 and O118 : H2. HUS developed in 16 (36.4 %) patients positive for VTEC virulence genes. All of the VTEC isolates produced a cytopathic effect on Vero cell monolayers, confirming the ability to express VT. Despite most strains being sensitive to all of the antimicrobials studied, a positive association between clinical progression to HUS and antibiotic therapy was observed for the total number of patients studied, as well as for the VTEC(+) group. In conclusion, the data obtained in this study increase our knowledge of the role and clinical course of VTEC infection in childhood acute diarrhoea beyond bloody diarrhoea, and might be considered for the prevention, diagnosis and management of this disease. It is possible that the optimal approach for VTEC diagnosis could be using multiplex PCR to search for the presence of the vt(1), vt(2

    OBJECTIVE: To analyse the incremental costs, effects and cost-effectiveness of zinc used as adjunct therapy to standard treatment of acute childhood diarrhoea, including dysentery, and to reassess the cost-effectiveness of standard case management with oral rehydration salt (ORS). METHODS: A decision tree was used to model expected clinical outcomes and expected costs under four alternative treatment strategies. The best available epidemiological, clinical and economic evidence was used in the calculations, and the United Republic of Tanzania was the reference setting. Probabilistic cost-effectiveness analysis was performed using a Monte-Carlo simulation technique and the potential impacts of uncertainty in single parameters were explored in one-way sensitivity analyses. FINDINGS: ORS was found to be less cost-effective than previously thought. The use of zinc as adjunct therapy significantly improved the cost-effectiveness of standard management of diarrhoea for dysenteric as well as non-dysenteric illness. The results were particularly sensitive to mortality rates in non-dysenteric diarrhoea, but the alternative interventions can be defined as highly cost-effective even in pessimistic scenarios. CONCLUSION: There is sufficient evidence to recommend the inclusion of zinc into standard case management of both dysenteric and non-dysenteric acute diarrhoea.A direct transfer of our findings from the United Republic of Tanzania to other settings is not justified, but there are no indications of large geographical differences in the efficacy of zinc. It is therefore plausible that our findings are also applicable to other developing countries. PMID:15500284

    To determine whether the risk factors for childhood haemolytic uraemic syndrome (HUS) are similar to risk factors previously reported for Escherichia coli O 157. H7 gastroenteritis, we conducted a case-control study at eight paediatric hospitals in the summer of 1990. Thirty-four consecutive children with HUS were prospectively enrolled; all had diarrhoea and 88% had laboratory evidence of exposure to verotoxin-producing E. coli (VTEC). The 102 controls were otherwise healthy children with minor acute injuries. Parents of all subjects responded to a questionnaire about each child's exposure to various foods, methods of food preparation, sources of water, travel, and individuals with diarrhoea. Children with HUS were significantly more likely than controls to have had close contact with an individual with diarrhoea in the 2 weeks before the onset of illness (74 v. 29%, P < 0.00001; odds ratio 7.0, 95% CI 2.7-18.5). The onset of diarrhoea in the contacts occurred a median of 6 days (range, 1- > 14 days) before the onset of diarrhoea in the HUS patients. Exposure to undercooked ground meat was not significantly more common in the patients with HUS (15 v. 8%; P = 0.05). These data provide evidence consistent with person-to-person transmission of VTEC in a substantial proportion of episodes of childhood HUS. PMID:8432328

    Until 1979, diarrhoeal disease accounted for roughly half of all infant and childhood deaths in Egypt, partly because curative care was largely inappropriate. The National Control of Diarrhoeal Diseases Project (NCDDP) addressed this problem from 1982 to 1991. Since 1979 many aspects of diarrhoeal disease in Egypt have been addressed in many studies. This paper reviews that literature, finding considerable improvements in case management, particularly in the use of oral rehydration solution and in feeding during diarrhoeal episodes. This is due primarily to the NCDDP. At the same time diarrhoeal mortality declined rapidly, both absolutely and as a percentage of total mortality. Persistent diarrhoeas, which have become an increasing proportion of the remaining mortality, have not been satisfactorily addressed, and irrational treatment with drugs remains a major problem.

    Evidence from the literature has shown that Saccharomyces boulardii provides a clinically significant benefit in the treatment of acute infectious diarrhoea in children. In this multicentre, randomised, prospective, controlled, single blind clinical trial performed in children with acute watery diarrhoea, we aimed to evaluate the impact of S. boulardii CNCM I-745 in hospitalised children, in children requiring emergency care unit (ECU) stay and in outpatient settings. The primary endpoint was the duration of diarrhoea (in hours). Secondary outcome measures were duration of hospitalisation and diarrhoea at the 3(rd) day of intervention. In the whole study group (363 children), the duration of diarrhoea was approximately 24 h shorter in the S. boulardii group (75.4±33.1 vs 99.8±32.5 h, P<0.001). The effect of S. boulardii (diarrhoea-free children) was observed starting at 48 h. After 72 h, only 27.3% of the children receiving probiotic still had watery diarrhoea, in contrast to 48.5% in the control group (P<0.001). The duration of diarrhoea was significantly reduced in the probiotic group in hospital, ECU and outpatient settings (P<0.001, P<0.01 and P<0.001, respectively). The percentage of diarrhoea-free children was significantly larger after 48 and 72 h in all settings. The mean length of hospital stay was shorter with more than 36 h difference in the S. boulardii group (4.60±1.72 vs 6.12±1.71 days, P<0.001). The mean length of ECU stay was shorter with more than 19 h difference in the probiotic group (1.20±0.4 vs 2.0±0.3 days, P<0.001). No adverse effects related to the probiotic were noted. Because treatment can shorten the duration of diarrhoea and reduce the length of ECU and hospital stay, there is likely a social and economic benefit of S. boulardii CNCM I-745 in adjunction to oral rehydration solution in acute infectious gastroenteritis in children.

    Background Diarrhoea disease which has been attributed to poverty constitutes a major cause of morbidity and mortality in children aged five and below in most low-and-middle income countries. This study sought to examine the contribution of individual and neighbourhood socio-economic characteristics to caregiver's treatment choices for managing childhood diarrhoea at household level in sub-Saharan Africa. Methods Multilevel multinomial logistic regression analysis was applied to Demographic and Health Survey data conducted in 11 countries in sub-Saharan Africa. The unit of analysis were the 12,988 caregivers of children who were reported to have had diarrhoea two weeks prior to the survey period. Results There were variability in selecting treatment options based on several socioeconomic characteristics. Multilevel-multinomial regression analysis indicated that higher level of education of both the caregiver and that of the partner, as well as caregivers occupation were associated with selection of medical centre, pharmacies and home care as compared to no treatment. In contrast, caregiver's partners' occupation was negatively associated with selection medical centre and home care for managing diarrhoea. In addition, a low-level of neighbourhood socio-economic disadvantage was significantly associated with selection of both medical centre and pharmacy stores and medicine vendors. Conclusion In the light of the findings from this study, intervention aimed at improving on care seeking for managing diarrhoea episode and other childhood infectious disease should jointly consider the influence of both individual SEP and the level of economic development of the communities in which caregivers of these children resides.

    Secondary lactose intolerance is often a cause of prolongation of diarrhoeal episodes. As appropriate management of lactose intolerance is elimination of lactose from diet, expansive lactose free formulae are often prescribed in acute childhood diarrhoea without establishing diagnosis of lactose intolerance. Since cheap weaning diets made from locally available cereals have been found effective in management of persistent diarrhoea, we postulated that same weaning diet made of rice lentil and yogurt (K-Y diet) could be effectively used in management of acute childhood diarrhoea associated with secondary lactose intolerance. We compared this K-Y diet with milk protein-based lactose free and soy-protein formula. Thirty children between 3-18 months of age completed dietary trial for 72 h. Of these nine children received K-Y diet (Group A), four children received milk protein-based formula (Group B) and 11 children received soy protein formula (Group C). Stool frequency was significantly reduced in children in Group A (13 +/- 6 on day 1 to 6 +/- 5 on day 3) and in Group B (13 +/- 5 on day 1 to 7 +/- 4 on day 3), but not in Group C (13 +/- 4 on day 1 to 10 +/- 8 on day 3). No significant difference was observed in intake of diet, total calories intake, and fluid intake among the three groups. It is concluded that cheap weaning diet made of locally available cereals and yogurt can be used effectively in management of secondary lactose intolerance associated with acute childhood diarrhoea.

    Diarrhoea is a major cause of short-term growth faltering in children of the developing world. If catch-up weight gain is delayed by inadequate dietary intake, or by further bouts of diarrhoea, progressive growth failure occurs. To test the hypothesis that early refeeding is as effective as later feeding after acute diarrhoea with weight loss, we measured the effects of a timed dietary intervention on weight gain after acute diarrhoea in underweight Gambian children. Thirty-four children aged 4-22 months with weight loss following acute diarrhoea were given a high-energy-protein supplement for 14 d beginning either immediately after rehydration or a fortnight later. With a 50% increase in energy intake and a 100% increase in protein intake there was a rapid and highly significant (P < 0.001) gain in weight within a fortnight whether the supplement was given immediately or 2 weeks after presentation. Rates of weight increase were similar whether supplementation was provided early or late, but over the full 28 d (of intervention and non-intervention) children who received late supplementation had greater overall weight gain (P < 0.02) than those supplemented early. Vigorous and early feeding with a high-energy-protein supplement should be central to the management of malnourished children with acute diarrhoea in developing countries, and may be as important as control of diarrhoea in preventing malnutrition and growth failure. This may be achieved in the community using locally available foods, in the face of continuing diarrhoea.

    Oral rehydration solution (ORS) and zinc are the recommended treatment in developing countries for the management of uncomplicated diarrhoea in children under five (World Health Organization and UNICEF 2004). However, drug sellers often recommend costly and unnecessary treatments instead. This article reports findings from an experiment to encourage licensed chemical sellers (LCS) in Ghana to recommend ORS and zinc for the management of childhood diarrhoea. The intervention consisted of mobile phone text messages (Short Message Service or SMS) sent to a randomly assigned group of LCS who had been trained on the diarrhoea management protocols recommended by the World Health Organization (WHO). The SMS campaign comprised informational messages and interactive quizzes sent over an 8-week period. The study measured the impact of the SMS messages on both reported and actual practices. Analysis of data from both face-to-face interviews and mystery client visits shows that the SMS intervention improved providers' self-reported practices but not their actual practices. The study also finds that actual practices deviate substantially from reported practices.

    Background & objectives: Randomized controlled trials in developed countries have reported benefits of Lactobacillus GG (LGG) in the treatment of acute watery diarrhoea, but there is paucity of such data from India. The study was aimed to evaluate the efficacy and safety of Lactobacillus GG in the treatment of acute diarrhoea in children from a semi-urban city in north India. Methods: In this open labelled, randomized controlled trial 200 children with acute watery diarrhoea, aged between 6 months to 5 years visiting outpatient department and emergency room of a teaching hospital in north India were enrolled. The children were randomized into receiving either Lactobacillus GG in dose of 10 billion cfu/day for five days or no probiotic medication in addition to standard WHO management of diarrhoea. Primary outcomes were duration of diarrhoea and time to change in consistency of stools. Results: Median (inter quartile range) duration of diarrhoea was significantly shorter in children in LGG group [60 (54-72) h vs. 78 (72-90) h; P<0.001]. Also, there was faster improvement in stool consistency in children receiving Lactobacillus GG than control group [36 (30-36) h vs. 42 (36-48) h; P<0.001]. There was significant reduction in average number of stools per day in LGG group (P<0.001) compared to the control group. These benefits were seen irrespective of rotavirus positivity in stool tests. Interpretation & conclusions: Our results showed that the use of Lactobacillus GG in children with acute diarrhoea resulted in shorter duration and faster improvement in stool consistency as compared to the control group.

    Academic detailing is rarely practised in developing countries. A randomized control trial on healthcare service was conducted to evaluate the impact of academic detailing programme on the adherence of primary healthcare providers in Banke district, Nepal, to childhood diarrhoea treatment guidelines recommended by World Health Organization/United Nations Children's Fund (WHO/UNICEF). The participants (N=209) were systematically divided into control and intervention groups. Four different academic detailing sessions on childhood diarrhoea management were given to participants in the intervention group. At baseline, 6% of the participants in the control and 8.3% in the intervention group were adhering to the treatment guidelines which significantly (p < 0.05) increased among participants in the intervention (65.1%) than in the control group (16.0%) at the first follow-up. At the second follow-up, 69.7% of participants in the intervention group were adhering to the guidelines, which was significantly (p < 0.05) greater than those in the control group (19.0%). Data also showed significant improvement in prescribing pattern of the participants in the intervention group compared to the control group. Therefore, academic detailing can be used for promoting adherence to treatment guidelines in developing countries, like Nepal.

    In 2004, the World Health Organization (WHO) and United Nations Children's Fund (UNICEF) jointly revised the recommended treatment for acute paediatric diarrhoea to specify supplementing reduced osmolarity oral rehydration salts (ORS) with zinc. In many countries, however, a significant knowledge-practice gap persists in appropriate diarrhoea management among private healthcare providers. For example, the United States Agency for International Development (USAID)-funded Strengthening Health Outcomes through the Private Sector (SHOPS) project recently demonstrated that over-the-counter medicine sellers (MS) in Ghana recommended inappropriate diarrhoea treatments, despite their demonstrated knowledge of appropriate treatment protocols. To explore and explain these results, we conducted 26 focus groups with MS and their customers using an indirect elicitation approach, presenting simulated drug shop transaction scenarios for each group to analyze and discuss. Through inductive and deductive data analysis, we found that the pattern of customer-MS interactions within the transactional context plays a critical role in shaping dispensing outcomes, not only in diarrhoea management but in other contexts as well. MS who engaged and negotiated with their customers were better able to introduce and promote the appropriate diarrhoea treatment protocol. Several factors hinder optimal interactions. Although MS in fact serve as frontline medical providers, they lack the perceived status of a clinician. Moreover, the need to maintain their customer base creates a power imbalance that favours accommodating customer requests and discourages educational interaction. Finally, many MS lack a complete understanding of the recommended treatment, limiting their ability to educate and negotiate. These findings have important implications for efforts to position community-level private providers to improve outcomes across a number of health areas; the study recommends three broad approaches

    A cross-sectional study was conducted to investigate the potential factors of food-hygiene practices of mothers on the prevalence of diarrhoea among their children. Mothers who had children aged 6 months–5 years were recruited in a hamlet in Viet Nam. The food-hygiene practices included hand-washing, method of washing utensils, separation of utensils for raw and cooked food, and the location where foods were prepared for cooking. A face-to-face interview was conducted, and data on 206 mothers were analyzed. The risk of diarrhoea was significantly higher among children whose mothers prepared food for cooking somewhere other than the table (typically on the ground) compared to children whose mothers prepared food on the table (adjusted odds ratio=2.85, 95% confidence interval 1.11–7.28). The results indicate that food-hygiene practices of mothers, such as avoiding preparing food for cooking on the ground, has a potential impact in preventing diarrhoea among children in Viet Nam.

    There have been very few longitudinal studies of diarrhoea morbidity in sub-Saharan Africa. This longitudinal study of children aged 3-35 months from 18 clusters of villages reports an annual incidence rate of 6.3 episodes per child in a rural area of Zaire, which is higher than a cross-sectional estimate previously obtained in the same district. The study confirms that a child's risk of diarrhoeal attack is associated with age, water quality and sanitation, parental education and household size. The findings suggest also that birth interval may be an important risk factor for diarrhoeal morbidity.

    Objectives Examine factors associated with use of traditional medicine during childbirth and in management of childhood diarrhoea. Design Cross-sectional cluster survey, household interviews in a stratified last stage random sample of 90 census enumeration areas; unstructured interviews with traditional doctors. Setting Oil-rich Cross River State in south-eastern Nigeria has 3.5 million residents, most of whom depend on a subsistence agriculture economy. Participants 8089 women aged 15–49 years in 7685 households reported on the health of 11 305 children aged 0–36 months in July–August 2011. Primary and secondary outcome measures Traditional medicine used at childbirth and for management of childhood diarrhoea; covariates included access to Western medicine and education, economic conditions, engagement with the modern state and family relations. Cluster-adjusted analysis relied on the Mantel-Haenszel procedure and Mantel extension. Results 24.1% (1371/5686) of women reported using traditional medicine at childbirth; these women had less education, accessed antenatal care less, experienced more family violence and were less likely to have birth certificates for their children. 11.3% (615/5425) of young children with diarrhoea were taken to traditional medical practitioners; these children were less likely to receive BCG, to have birth certificates, to live in households with a more educated head, or to use fuel other than charcoal for cooking. Education showed a gradient with decreasing use of traditional medicine for childbirth (χ2 135.2) and for childhood diarrhoea (χ2 77.2). Conclusions Use of traditional medicine is associated with several factors related to cultural transition and to health status, with formal education playing a prominent role. Any assessment of the effectiveness of traditional medicine should anticipate confounding by these factors, which are widely recognised to affect health in their own right. PMID:27094939

    Calf diarrhoea causes substantial economic losses in cattle herds worldwide. Neonatal calves are particularly sensitive to infections with enteropathogens. The present study focused on prevention against the main infectious causes of neonatal calf diarrhoea i.e. Escherichia coli, rota- and coronavirus, and Cryptosporidium parvum. Dairy herds (n=24) with a high percentage of neonatal calves scouring (>10%) were included and calves were sampled for the presence of these four enteropathogens. To decrease diarrhoea problems among neonatal calves, a standard protocol was tested on 13 herds (treatment group) where both C. parvum and either E. coli or rota- or coronavirus were identified as being involved, the other 11 herds served as control group. The protocol consisted of 2 points of action: preventive vaccination of dams against E. coli, rota- and coronavirus, and preventive administration of halofuginone lactate to newborn calves. The average percentage of calves suffering from neonatal diarrhoea (39.7% versus 14.3%, P<0.01) and the average percentage of faecal samples positive for C. parvum (34% versus 11%, P<0.05) differed significantly between control herds and treatment herds after implementation of the protocol. No significant differences between control and treatment group were observed in the percentage of calves excreting E. coli, rotavirus and coronavirus, both before and at the end of the trial. Furthermore, risk factors potentially associated with the development of neonatal calf scours were determined. Non-significant results were obtained for the effect of the protocol on duration of diarrhoea and the effect of the colostral IgG quantity on the risk of diarrhoea. Passive immunity transfer status of the calves, measured both before the onset and at the end of the study, were non-significant between groups.

    Previous clinical vitamin A trials have found no consistent effect on diarrhoeal disease and respiratory tract infection. These inconsistent results may be due to the distinct effects vitamin A supplementation has among children stratified by factors related to socio-economic status, nutritional status and season. We evaluated the effect of supplementation on the overall incidence of diarrhoeal disease and respiratory tract infections and on the incidence among children stratified by these factors. A total of 188 children, aged 6-15 months, from periurban, marginalized communities of Mexico City were assigned to receive vitamin A ( < 12 months of age, 20,000 IU retinol; >or= 12 months, 45,000 IU retinol) or a placebo every 2 months, and were followed for up to 15 months. Project personnel visited households twice a week to determine the onset and duration of diarrhoeal disease and respiratory tract infections. Vitamin A supplementation had no significant effect on risk of overall diarrhoeal disease but reduced mild watery diarrhoea (incidence rate ratio (RR) 0.69; 95 % CI 0.50, 0.93) and cough with fever (RR 0.69; 95 % CI 0.48, 0.98). Vitamin A supplementation decreased diarrhoeal disease during the summer (RR 0.74; 95 % CI 0.57, 0.94), among non-stunted children (RR 0.69; 95 % CI 0.52, 0.93) and among children from households with better socio-economic measures. Heterogeneity in the response to vitamin A supplementation may reflect heterogeneity in the aetiology and epidemiology of diarrhoeal disease and respiratory tract infections and the impact that supplementation has on the immune response.

    In this research project, we studied factors that presumably affect the incidence of diarrhoea among young children in urban slums in developing countries: consumption of safe drinks, hygiene behaviour, cleanliness of household surroundings and the quality of raw water. Beliefs concerning the causes of diarrhoea were also related to health-improving behaviour, namely the application of the water-treatment method SODIS (solar water disinfection) and hygiene behaviour. We conducted a survey in a shanty town in Nairobi, Kenya. Field workers interviewed 500 households. Analysis with regression models revealed that two out of the four postulated factors were significant: children have a lower risk of contracting diarrhoea when they consume high percentages of safe drinks and live in households with good hygiene. As regards beliefs, we found that biomedical knowledge of children's diarrhoea as well as the perceived social norm for treating water was associated with the use of SODIS and good hygiene.

    Many physicians are resistant to the idea of prescribing loperamide for acute infectious traveller's diarrhoea and community-acquired diarrhoea because of the fear of possible adverse effects. Large randomized trials with loperamide, either alone or as an adjunct to antibiotic treatment, have in fact revealed positive rather than negative effects. International guidelines now often support the use of loperamide for the treatment of infectious diarrhoea without dysentery. There seems to be no reason to systematically avoid loperamide in patients with dysentery, but caution is advised. Loperamide can be used as monotherapy or as an adjunct to antibiotic treatment in immunocompetent adults with acute infectious traveller's diarrhoea or community-acquired diarrhoea without severe comorbidities. This can reduce both the frequency of diarrhoea and the time until the diarrhoea stops without the risk of severe complications.

    Traveller's diarrhoea (TD) is acquired primarily through ingestion of food and drinks contaminated with pathogens that cause diarrhoea. They can be bacteria, protozoa, helminths, and viruses. Globally, the most common causes of TD are two pathotypes of Escherichia coli (enterotoxigenic and enteroaggregative) and Campylobacter, although there are significant variations by geographic area visited. Most TD occurs in individuals traveling to low-middle income countries. The type of travel, length of stay, traveller's age, and the presence of certain underlying conditions are important risk factors to consider for the acquisition of TD. While TD is usually a mild and self-limiting disease, half of travellers with TD experience some limitation of activities during their trip, while up to 10% will experience persistent diarrhoea or other complications. The purpose of this article is to provide an updated microbiological, epidemiological, and clinical profile of traveller's diarrhoea, including known risk factors, as well as to make recommendations on the prevention and treatment of TD.

    Traveller's diarrhoea affects over 50% of travellers to some destinations and can disrupt holidays and business trips. This review examines the main causes and epidemiology of the syndrome, which is associated with poor public health infrastructure and hygiene practices, particularly in warmer climates. Although travellers may be given common sense advice on avoidance of high-risk foods and other measures to prevent traveller's diarrhoea, adherence to such advice is sometimes difficult and the evidence for its effectiveness is contradictory. However, non-antimicrobial means for prevention of traveller's diarrhoea are favoured in most settings. A simple stepwise approach to the management of traveller's diarrhoea includes single doses or 3-day courses of antimicrobials, often self administered. The antibiotics of choice are currently fluoroquinolones or azithromycin, with an emerging role for rifaximin. In the long term, there will be greater benefit and effect on the health of local inhabitants and travellers from improving public health and hygiene standards at tourist destinations.

    The stepwise implementation of the Tehran Sewerage Project provided a convenient setting for which health impacts of an urban sewerage system could be examined with appropriate controls. In 2001, Tehran municipal districts 17 and 18 had no sewerage system connections, but areas within these districts had been planned to be connected by 2006. These areas were chosen as an intervention group. Neighbouring areas, with a similar socio-economic status, that had not been planned to connect to the sewerage system by 2006, were chosen as controls. Homes within designated areas were randomized and surveyed twice to determine diarrhoea incidences for children aged 6-60 months, once in 2001, before connection to the sewerage system, and once again in 2006, after the intervention. By 2006, 76% of the homes in the intervention zones were connected to the sewerage system. In the first stage of the study, diarrhoea incidences for intervention and control groups were 18.6 and 16.6%, respectively. In the second stage, incidences decreased to 10.1 and 10.5%, respectively. Data collected from 4179 children demonstrated that the diarrhoea incidence had decreased by 46% in the intervention group, whereas it had decreased by 37% in the controls.

    We present qualitative research findings on care-seeking and treatment uptake for pneumonia, diarrhoea and malaria among children under 5 in Kenya, Nigeria and Niger. The study aimed to determine the barriers caregivers face in accessing treatment for these conditions; to identify local solutions that facilitate more timely access to treatment; and to present these findings as a platform from which to develop context-specific strategies to improve care-seeking for childhood illness. Kenya, Nigeria and Niger are three high burden countries with low rates of related treatment coverage, particularly in underserved areas. Data were collected in Homa Bay County in Nyanza Province, Kenya; in Kebbi and Cross River States, Nigeria; and in the Maradi and Tillabéri regions of Niger. Primary caregivers of children under 5 who did not regularly engage with health services or present their child at a health facility during illness episodes were purposively selected for interview. Data underwent rigorous thematic analysis. We organise the identified barriers and related solutions by theme: financial barriers; distance/location of health facilities; socio-cultural barriers and gender dynamics; knowledge and information barriers; and health facility deterrents. The relative importance of each differed by locality. Participant suggested solutions ranged from community-level actions to facility-level and more policy-oriented actions, plus actions to change underlying problems such as social perceptions and practices and gender dynamics. We discuss the feasibility and implications of these suggested solutions. Given the high burden of childhood morbidity and mortality due to pneumonia, diarrhoea and malaria in Kenya, Nigeria and Niger, this study provides important insights relating to demand-side barriers and locally proposed solutions. Significant advancements are possible when communities participate in both problem identification and resolution, and are engaged as important

    2011-01-01

    Congenital diarrhoea of heterogenic etiology is a rare cause of chronic diarrhoea. Characteristic features are: onset in the first weeks of life, life-threatening severe dehydratation and electrolyte disorders leading to a necessity of long-term parenteral nutrition. The clinical onset may be delayed and the degree of diarrhoea may be modest, making the diagnosis difficult. The main causes of congenital diarrhoea such as intestine electrolytes, carbohydrates, lipid and protein transport disorders and congenital enzymatic deficiencies, enterocyte polarization disorders, hormonal, immunological, metabolic, genetic and congenital anatomic disorders are presented in the paper. Some of them, such as: microvillus inclusion disease, tufting enteropathy, intestinal anedocrynosis, IPEX syndrome (immunodysregulation polyendocrinopathy enteropathy X-linked syndrome) have been described recently. One of the basic investigations, when congenital diarrhea is suspected, is general examination of the stool, its electrolyte concentration and serum electrolytes and blood gas analysis. Often, small bowel biopsy with histological examination (with the use of electronic microscopy and PAS staining) is indicated. In some cases molecular examination is possible and indicated. In differential diagnosis other, more frequent causes of chronic diarrhea of infancy, have to be excluded. In most of the cases of congenital diarrhoea there is no casual treatment available - usually long-term parenteral nutrition is necessary.

    Risk factors for care-seeking choices for childhood diarrhea in Nigeria are poorly understood. They are essential to the control of childhood illnesses because diarrhea is an important cause of childhood mortality. This study explored the contributors to care-seeking choices in Cross River State, Nigeria. Caregivers of children aged 0-59months in 1240 randomly selected households in Cross River State were involved in this cross-sectional study. Questionnaires were used to collect information on demographics, knowledge of illness, and care-seeking patterns, and observed associations were explored using logistic regression. Care was given at home (50.4%, n=142; as recommended), at the health center (27%, n=76), and at the local drug store (19.1%, n=54). Main reasons for care sought were health education (31.9%, n=94), treatment cost (18%, n=53), and experiences (16.6%, n=49). Caregivers living in the mainly urban area of Calabar Municipality [Adjusted Odds Ratio (AOR)=2.81 (1.26-6.26)] and the mainly rural area of Obanliku [AOR=3.59 (1.94-6.64)], were more likely to give home treatment. Choice of treatment was only associated with area of residence. Influencers of care-seeking behavior, especially for childhood diarrhea, are complex and need to be better understood to encourage enhanced care for young children with diarrhea.

    2011-01-01

    Introduction An estimated 4.6 billion cases of diarrhoea occurred worldwide in 2004, resulting in 2.2 million deaths. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for acute diarrhoea in adults living in resource-rich countries? What are the effects of treatments for acute mild-to-moderate diarrhoea in adults from resource-rich countries travelling to resource-poor countries? What are the effects of treatments for acute mild-to-moderate diarrhoea in adults living in resource-poor countries? What are the effects of treatments for acute severe diarrhoea in adults living in resource-poor countries? We searched: Medline, Embase, The Cochrane Library, and other important databases up to January 2010 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 72 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics, antimotility agents, antisecretory agents, bismuth subsalicylate, diet, intravenous rehydration, nasogastric tube rehydration, oral rehydration solutions (amino acid oral rehydration solution, bicarbonate oral rehydration solution, reduced osmolarity oral rehydration solution, rice-based oral rehydration solution, standard oral rehydration solution), vitamin A supplementation, and zinc supplementation.

  2. The potential use of cholestyramine to reduce the risk of developing Clostridium difficile-associated diarrhoea in patients receiving long-term intravenous ceftriaxone.

    2015-01-01

    Intravenous pharmacotherapy with the third-generation cephalosporin ceftriaxone is unfortunately associated with a relatively high incidence of Clostridium difficile-associated diarrhoea. Cholestyramine (colestyramine) is an anion-binding resin which can bind luminal C.difficile toxin A (TcdA) and toxin B (TcdB) and which may be beneficial in the treatment of recurrent antibiotic-associated pseudomembranous colitis. We therefore hypothesised that concomitant oral cholestyramine might reduce the risk of C.difficile-associated diarrhoea in patients receiving long-term intravenous ceftriaxone. A pilot study was carried out in which it was found that only three out of 46 (6.5%) such patients being treated with 2 g ceftriaxone daily for Lyme borreliosis, who also received 4 g cholestyramine daily, developed C.difficile-associated diarrhoea. This is smaller than a published report of the incidence of this complication in six out of 26 (23.1%) patients following 1-3 days' treatment with 1 g intravenous ceftriaxone, but without oral cholestyramine (p=0.06). We therefore recommend that a larger, double-blind placebo-controlled trial be carried out to test this hypothesis.

    In developing countries the highest incidence of diarrhoea occurs among infants who are given fluids or foods to supplement or replace breast-feeding, and numerous studies have been conducted to examine the relationship between feeding practices during the weaning period and the risk of diarrhoea and malnutrition. This Memorandum summarizes current knowledge about the potential impact of improved infant feeding practices on diarrhoeal morbidity and mortality and describes experiences gained with interventions to promote improved practices. Further research activities to examine the role of improved infant feeding practices in the control of diarrhoeal diseases and to identify more effective approaches to the promotion of such practices in the context of a public health programme are also proposed. Finally, methodological issues concerning the design, implementation, and analysis of intervention studies are reviewed. PMID:2706725

    Abstract Objective To assess, by socioeconomic setting, the effect of nationwide vaccination against species A rotavirus (RVA) on childhood diarrhoea-related hospitalizations in Mexico. Methods Data on children younger than 5 years who were hospitalized for diarrhoea in health ministry hospitals between 1 January 2003 and 31 December 2011 were collected from monthly discharge reports. Human development indexes were used to categorize the states where hospitals were located as having generally high, intermediate or low socioeconomic status. Annual rates of hospitalization for diarrhoea – per 10 000 hospitalizations for any cause – were calculated. Administrative data were used to estimate vaccine coverage. Findings In the states with high, intermediate and low socioeconomic status, coverage with a two-dose monovalent RVA vaccine – among children younger than 5 years – had reached 93%, 86% and 71%, respectively, by 2010. The corresponding median annual rates of hospitalization for diarrhoea – per 10 000 admissions – fell from 1001, 834 and 1033 in the “prevaccine” period of 2003–2006, to 597, 497 and 705 in the “postvaccine” period from 2008 to 2011, respectively. These decreases correspond to rate reductions of 40% (95% confidence interval, CI: 38–43), 41% (95% CI: 38–43) and 32% (95% CI: 29–34), respectively. Nationwide, RVA vaccination appeared to have averted approximately 16 500 hospitalizations for childhood diarrhoea in each year of the postvaccine period. Conclusion Monovalent RVA vaccination has substantially reduced childhood diarrhoea-related hospitalizations for four continuous years in discretely different socioeconomic populations across Mexico.

    Background Childhood obesity prevalence remains high in the U.S., especially among racial/ethnic minorities and low-income populations. Federal policy is important in improving public health given its broad reach. Information is needed about federal policies that could reduce childhood obesity rates and by how much. Purpose To estimate the impact of three federal policies on childhood obesity prevalence in 2032, after 20 years of implementation. Methods Criteria were used to select the three following policies to reduce childhood obesity from 26 recommended policies: afterschool physical activity programs, a $0.01/ounce sugar-sweetened beverage (SSB) excise tax, and a ban on child-directed fast food TV advertising. For each policy, the literature was reviewed from January 2000 through July 2012 to find evidence of effectiveness and create average effect sizes. In 2012, a Markov microsimulation model estimated each policy’s impact on diet or physical activity, and then BMI, in a simulated school-aged population in 2032. Results The microsimulation predicted that afterschool physical activity programs would reduce obesity the most among children aged 6–12 years (1.8 percentage points) and the advertising ban would reduce obesity the least (0.9 percentage points). The SSB excise tax would reduce obesity the most among adolescents aged 13–18 years (2.4 percentage points). All three policies would reduce obesity more among blacks and Hispanics than whites, with the SSB excise tax reducing obesity disparities the most. Conclusions All three policies would reduce childhood obesity prevalence by 2032. However, a national $0.01/ounce SSB excise tax is the best option. PMID:25175764

    Diarrhoea is one of the commonest reasons children require health care in Papua New Guinea (PNG). Acute watery diarrhoea is the commonest form, and is due to viruses. Oral rehydration solution, zinc and continued breastfeeding are highly effective treatments that can be delivered in homes and health facilities. Antibiotics are not useful in acute watery diarrhoea--they make it worse. Deaths from acute watery diarrhoea should be rare if basic curative services are available. Persistent diarrhoea (lasting longer than 14 days) is commonly associated with other co-morbidities, including malnutrition, anaemia, HIV (human immunodeficiency virus) infection, parasite (such as Giardia) or worm infections and environmental enteropathy. Educating parents on handwashing, food preparation, water purification, improvements in sanitation and the home environment, breastfeeding, nutrition and immunization are essential in preventing diarrhoea. Cholera appeared in PNG in 2009, causing over 500 deaths in all age groups. Cholera emerged because of limited access to safe, clean drinking water and poor sanitation. Addressing these will have beneficial effects not only on cholera but also on all causes of diarrhoea and many other common childhood infections.

    2000-01-01

    Diarrhoea is a relatively frequent adverse event, accounting for about 7% of all drug adverse effects. More than 700 drugs have been implicated in causing diarrhoea; those most frequently involved are antimicrobials, laxatives, magnesium-containing antacids, lactose- or sorbitol-containing products, nonsteroidal anti-inflammatory drugs, prostaglandins, colchicine, antineoplastics, antiarrhythmic drugs and cholinergic agents. Certain new drugs are likely to induce diarrhoea because of their pharmacodynamic properties; examples include anthraquinone-related agents, alpha-glucosidase inhibitors, lipase inhibitors and cholinesterase inhibitors. Antimicrobials are responsible for 25% of drug-induced diarrhoea. The disease spectrum of antimicrobial-associated diarrhoea ranges from benign diarrhoea to pseudomembranous colitis. Several pathophysiological mechanisms are involved in drug-induced diarrhoea: osmotic diarrhoea, secretory diarrhoea, shortened transit time, exudative diarrhoea and protein-losing enteropathy, and malabsorption or maldigestion of fat and carbohydrates. Often 2 or more mechanisms are present simultaneously. In clinical practice, 2 major types of diarrhoea are seen: acute diarrhoea, which usually appears during the first few days of treatment, and chronic diarrhoea, lasting more than 3 or 4 weeks and which can appear a long time after the start of drug therapy. Both can be severe and poorly tolerated. In a patient presenting with diarrhoea, the medical history is very important, especially the drug history, as it can suggest a diagnosis of drug-induced diarrhoea and thereby avoid multiple diagnostic tests. The clinical examination should cover severity criteria such as fever, rectal emission of blood and mucus, dehydration and bodyweight loss. Establishing a relationship between drug consumption and diarrhoea or colitis can be difficult when the time elapsed between the start of the drug and the onset of symptoms is long, sometimes up to several

    Background Worldwide, the public health community has recognized the growing problem of childhood obesity. But, unlike tobacco control policy, there is little evidence about what public policies would work to substantially reduce childhood obesity. Public health leaders currently tend to support traditional "command and control" schemes that order private enterprises and governments to stop or start doing specific things that, is it hoped, will yield lower childhood obesity rates. These include measures such as 1) taking sweetened beverages out of schools, 2) posting calorie counts on fast-food menu boards, 3) labeling foods with a "red light" if they contain high levels of fat or sugar, 4) limiting the density of fast food restaurants in any neighborhood, 5) requiring chain restaurants to offer "healthy" alternatives, and 6) eliminating junk food ads on television shows aimed at children. Some advocates propose other regulatory interventions such as 1) influencing the relative prices of healthy and unhealthy foods through taxes and/or subsidies and 2) suing private industry for money damages as a way of blaming childhood obesity on certain practices of the food industry (such as its marketing, product composition, or portion size decisions). The food industry generally seeks to deflect blame for childhood obesity onto others, such as parents and schools. PMID:19017402

    Diarrhoea in infants and young children is defined as >200g/day of stools, and occurs when there is an imbalance between intestinal fluids absorption and secretion. This may be caused by either a decreased absorption (osmotic diarrhoea) or an increased secretion (secretory diarrhoea). Chronic diarrhoea defines intestinal loss of water and electrolytes with increased stool frequency, reduced consistency and larger volume over more than 14days. This disorder in children shows a wide range of aetiologies depending on the age. The knowledge of common and rare aetiologies is important to optimize the diagnostic approach. A stepwise approach, starting with a comprehensive history, physical examination, inspection and collection of stool samples, helps to devise appropriate diagnostic and therapeutic management. In this article we discuss the pathophysiology, aetiology and possible approach to chronic diarrhoea in infancy.

    Diarrhoeal disease remains a major health burden worldwide. Secretory diarrhoeas are caused by certain bacterial and viral infections, inflammatory processes, drugs and genetic disorders. Fluid secretion across the intestinal epithelium in secretory diarrhoeas involves multiple ion and solute transporters, as well as activation of cyclic nucleotide and Ca(2+) signalling pathways. In many secretory diarrhoeas, activation of Cl(-) channels in the apical membrane of enterocytes, including the cystic fibrosis transmembrane conductance regulator and Ca(2+)-activated Cl(-) channels, increases fluid secretion, while inhibition of Na(+) transport reduces fluid absorption. Current treatment of diarrhoea includes replacement of fluid and electrolyte losses using oral rehydration solutions, and drugs targeting intestinal motility or fluid secretion. Therapeutics in the development pipeline target intestinal ion channels and transporters, regulatory proteins and cell surface receptors. This Review describes pathogenic mechanisms of secretory diarrhoea, current and emerging therapeutics, and the challenges in developing antidiarrhoeal therapeutics.

    Diarrhoea and vomiting are common symptoms in infants up to six months of age. While the symptoms often reflect a gastrointestinal disorder the attending physician needs to be aware of possible non gastrointestinal causes. Such symptoms occurring in the newborn often point to congenital causes. Dehydration and nutrition are the key points needing attention in the management of diarrhoea in infants. Drugs virtually have no role in the management of diarrhoea and vomiting in infants.

    2013-01-01

    Acute diarrhoea is a leading cause of child mortality in developing countries. Principal pathogens include Escherichia coli, rotaviruses, and noroviruses. 90% of diarrhoeal deaths are attributable to inadequate sanitation. Acute diarrhoea is the second leading cause of overall childhood mortality and accounts for 18% of deaths among children under five. In 2004 an estimated 1.5 million children died from diarrhoea, with 80% of deaths occurring before the age of two. Treatment goals are to prevent dehydration and nutritional damage and to reduce duration and severity of diarrhoeal episodes. The recommended therapeutic regimen is to provide oral rehydration solutions (ORS) and to continue feeding. Although ORS effectively mitigates dehydration, it has no effect on the duration, severity, or frequency of diarrhoeal episodes. Adjuvant therapy with micronutrients, probiotics, or antidiarrhoeal agents may thus be useful. The WHO recommends the use of zinc tablets in association with ORS. The ESPGHAN/ESPID treatment guidelines consider the use of racecadotril, diosmectite, or probiotics as possible adjunctive therapy to ORS. Only racecadotril and diosmectite reduce stool output, but no treatment has yet been shown to reduce hospitalisation rate or mortality. Appropriate management with validated treatments may help reduce the health and economic burden of acute diarrhoea in children worldwide. PMID:23533446

The most common cause of travellers' diarrhoea worldwide is bacterial pathogens, which account for up to 80% of cases. Exercising caution over dietary selection and personal hygiene is the most common method used for reducing the risk of acquiring travellers' diarrhoea. Antibiotics, probiotics, prebiotics and bismuth subsalicylate have all been indicated for the prevention of this distressing condition. Treatments include antimotility agents, oral rehydration salts and antibiotics.

    Infections are an uncommon cause of chronic diarrhoea. Parasites are most likely, including protozoa like giardia, cryptosporidia and cyclospora. Bacteria are unlikely to cause chronic diarrhoea in immunocompetent individuals with the possible exception of Yersinia, Plesiomonas and Aeromonas. Infectious diarrhoea can trigger other causes of chronic diarrhoea, including inflammatory bowel disease, irritable bowel syndrome and "Brainerd-type" diarrhoea. A thorough evaluation should detect most infections causing chronic diarrhoea.

    Pneumonia is an illness, usually caused by infection, in which the lungs become inflamed and congested, reducing oxygen exchange and leading to cough and breathlessness. It affects individuals of all ages but occurs most frequently in children and the elderly. Among children, pneumonia is the most common cause of death worldwide. Historically, in developed countries, deaths from pneumonia have been reduced by improvements in living conditions, air quality, and nutrition. In the developing world today, many deaths from pneumonia are also preventable by immunization or access to simple, effective treatments. However, as we highlight here, there are critical gaps in our understanding of the epidemiology, etiology, and pathophysiology of pneumonia that, if filled, could accelerate the control of pneumonia and reduce early childhood mortality.

    Summary Background A city-wide sanitation intervention was started in Salvador, Brazil, in 1997 to improve sewerage coverage from 26% of households to 80%. Our aim was to investigate the epidemiological effect of this city-wide sanitation programme on diarrhoea morbidity in children less than 3 years of age. Methods The investigation was composed of two longitudinal studies done in 1997–98 before the intervention (the sanitation programme) and in 2003–04 after the intervention had been completed. Each study consisted of a cohort of children (841 in the preintervention study and 1007 in the postintervention study; age 0–36 months at baseline) who were followed up for a maximum of 8 months. Children were sampled from 24 sentinel areas that were randomly chosen to represent the range of environmental conditions in the study site. At the start of each study an individual or household questionnaire was applied by trained fieldworkers; an environmental survey was done in each area before and after introduction of the sanitation programme to assess basic neighbourhood and household sanitation conditions. Daily diarrhoea data were obtained during home visits twice per week. The effect of the intervention was estimated by a hierarchical modelling approach fitting a sequence of multivariate regression models. Findings Diarrhoea prevalence fell by 21% (95% CI 18–25%)—from 9·2 (9·0–9·5) days per child-year before the intervention to 7·3 (7·0–7·5) days per child-year afterwards. After adjustment for baseline sewerage coverage and potential confounding variables, we estimated an overall prevalence reduction of 22% (19–26%). Interpretation Our results show that urban sanitation is a highly effective health measure that can no longer be ignored, and they provide a timely support for the launch of 2008 as the International Year of Sanitation.

    Background Policy discussions and debates in the last couple of decades emphasized efficiency of development policies for translating economic growth to development. One of the key aspects in this regard in the developing world is achieving improved nutrition through economic development. Nonetheless, there is a dearth of literature that empirically verifies the association between economic growth and reduction of childhood undernutrition in low- and middle-income countries. Thus, the aim of the study is to assess the interplay between economic growth and reduction of childhood undernutrition in Ethiopia. Methods The study used pooled data of three rounds (2000, 2005 and 2010) from the Demographic and Health Surveys (DHS) of Ethiopia. A multilevel mixed logistic regression model with robust standard errors was utilized in order to account for the hierarchical nature of the data. The dependent variables were stunting, underweight, and wasting in children in the household. The main independent variable was real per capita income (PCI) that was adjusted for purchasing power parity. This information was obtained from World Bank. Results A total of 32,610 children were included in the pooled analysis. Overall, 11,296 (46.7%) [46.0%-47.3%], 8,197(33.8%) [33.2%-34.4%] and 3,175(13.1%) [12.7%-13.5%] were stunted, underweight, and wasted, respectively. We found a strong correlation between prevalence of early childhood undernutrition outcomes and real per capita income (PCI). The proportions of stunting (r = -0.1207, p<0.0001), wasting (r = -0.0338, p<0.0001) and underweight (r = -0.1035, p<0.0001) from the total children in the household were negatively correlated with the PCI. In the final model adjustment with all the covariates, economic growth substantially reduced stunting [β = -0.0016, SE = 0.00013, p<0.0001], underweight [β = -0.0014, SE = 0.0002, p<0.0001] and wasting [β = -0.0008, SE = 0.0002, p<0.0001] in Ethiopia over a decade.

    2014-01-01

    Among 1-19-year olds, unintentional injuries accounted for 12% of 5.1 million global deaths from injuries in 2010. Despite this high burden, childhood injuries have not received much attention in global health. This paper describes the major causes of deaths from childhood unintentional injuries and provides a review of interventions for reducing this burden. About 627,741 deaths were due to unintentional injuries in 2010 among 1-19-year olds. The proportionate mortality increased with age-from 12.6% among 1-4-year olds to 28.8% among 15-19-year olds. Deaths from Western sub-Saharan Africa and South Asia accounted for more than 50% of all deaths. Rates in these regions are 68.0 and 36.4 per 100 000 population, respectively, compared to 6.4 in Western Europe. Road traffic injuries (RTI) are the commonest cause of death, followed by deaths from drowning, burns and falls. Male children are more predisposed to unintentional injuries except for burns which occur more frequently among females in low and middle income countries (LMICs). Effective solutions exist--including barriers for preventing drowning; safer stoves for burns; child restraint systems for RTI--but the effectiveness of these measures need to be rigorously tested in LMICs. The general lack of a coordinated global response to the burden of childhood unintentional injuries is of concern. The global community must create stronger coalitions and national or local plans for action. Death rates for this paper may have been underestimated, and there is need for longitudinal studies to accurately measure the impact of injuries in LMICs.

    Background Patients with irritable bowel syndrome with diarrhoea (IBS-D) experience restriction in daily activities and decreased health-related quality of life (QOL). Aim To investigate effects of alosetron on patient-reported health-related QOL, satisfaction and productivity in women with severe IBS-D. Methods A total of 705 women (severe IBS-D, Rome II criteria) randomised to alosetron 0.5 mg QD, 1 mg QD, 1 mg BID, or placebo for 12 weeks were studied. IBSQOL, treatment satisfaction, daily activities, and lost workplace productivity (LWP) were evaluated at randomisation and Week 12. Results One or more doses of alosetron significantly improved all IBSQOL domains except for sexual function from baseline vs. placebo. The magnitude of IBSQOL changes was consistent with a clinically meaningful effect. Alosetron 0.5 mg QD and 1 mg BID significantly reduced IBS interference with social/leisure activities and LWP from baseline vs. placebo [social/leisure (mean ±S.E.) days lost: −6.7 ± 0.8, −7.0 ± 0.9, P < 0.01; LWP (mean ± S.E.) h lost: −11.0 ± 3.3, −21.1 ± 4.1, P < 0.05 respectively]. Significantly more patients treated with alosetron reported satisfaction vs. placebo. Improvements in IBSQOL, LWP, and treatment satisfaction significantly correlated with global improvement of IBS symptoms. The incidence of adverse events with alosetron was low with constipation being the most commonly reported event. A single case of ischaemic colitis occurred, in a patient receiving alosetron 0.5 mg QD. Conclusions In women with severe IBS-D, alosetron treatment, including 0.5 mg QD, resulted in statistically significant and clinically relevant improvements in health-related QOL, restriction of daily activities and treatment satisfaction over placebo. IBS symptom improvement corresponded with positive changes in IBSQOL, LWP and treatment satisfaction. PMID:22779693

    Lactose intolerance is frequently encountered in children with persistent diarrhoea (PD). Selection of an appropriate milk-based formulation is a major management problem in the developing world. In a consecutive series of studies, we evaluated the role of feeding a traditional rice-lentil (khitchri) diet alone (KY) or in combination with either soy formula (KY-Soy) a dilute buffalo milk (KY-B), in children (age 6 months-3 years) with PD. Serial observations of stool output, caloric intake and weight gain of these children over a 14 day period indicated satisfactory tolerance of the KY diet with adequate weight gain. The weight gain and stool output was however higher in lactose intolerant children, with the worst results seen with K-Y and buffalo milk combination. While lactose intolerant children with PD do have higher. rates of therapeutic failure, our data indicates that a traditional diet and yogurt combination can be used satisfactorily for nutritional rehabilitation in over 80% of such children.

    Background The impacts of optimal infant feeding practices on diarrhoea have been documented in some developing countries, but not in countries with high diarrhoea mortality as reported by the World Health Organisation/United Nations Children’s Fund. We aimed to investigate the association between infant feeding practices and diarrhoea in sub-Saharan African countries with high diarrhoea mortality. Method The study used the most recent Demographic and Health Survey datasets collected in nine sub-Saharan African countries with high diarrhoea mortality, namely: Burkina Faso (2010, N = 9,733); Demographic Republic of Congo (2013; N = 10,458); Ethiopia (2013, N = 7,251); Kenya (2014, N = 14,034); Mali (2013, N = 6,365); Niger (2013, N = 7,235); Nigeria (2013, N = 18,539); Tanzania (2010, N = 5,013); and Uganda (2010, N = 4,472). Multilevel logistic regression models that adjusted for cluster and sampling weights were used to investigate the association between infant feeding practices and diarrhoea in these nine African countries. Results Diarrhoea prevalence was lower among children whose mothers practiced early initiation of breastfeeding, exclusive and predominant breastfeeding. Early initiation of breastfeeding and exclusive breastfeeding were significantly associated with lower risk of diarrhoea (OR = 0.81; 95% confidence interval (CI): 0.77–0.85, P<0.001 and OR = 0.50; 95%CI: 0.43–0.57, respectively). In contrast, introduction of complementary foods (OR = 1.31; 95%CI: 1.14–1.50) and continued breastfeeding at one year (OR = 1.27; 95%CI: 1.05–1.55) were significantly associated with a higher risk of diarrhoea. Conclusion Early initiation of breastfeeding and exclusive breastfeeding are protective of diarrhoea in sub-Saharan African countries with high diarrhoea mortality. To reduce diarrhoea mortality and also achieve the health-related sustainable development goals in sub-Saharan African, an integrated, multi-agency strategic partnership within each

    Sleep loss alters processing of emotional stimuli in preschool-aged children. However, the mechanism by which sleep modifies emotional processing in early childhood is unknown. We tested the hypothesis that a nap, compared to an equivalent time spent awake, reduces biases in attention allocation to affective information. Children (n = 43; M = 55.40 months, SD = 8.05 months) completed a Dot Probe task, which provides a measure of attention biases to emotional stimuli, following a mid-day nap and an equivalent interval spent awake. No emotional attention biases emerged when children napped. However, when nap-deprived, children exhibited biases towards negative and positive stimuli. This emotional bias after wake was greater in children who napped habitually. Gender differences also emerged such that females were more attentive to positive emotional stimuli whereas males showed heightened attention to negative emotional stimuli, regardless of having napped or not. Moreover, greater slow wave activity (SWA) during the nap was associated with faster responding, which suggests that SWA may promote efficiency of attention allocation.

    Novel approaches are needed to reduce the high rates of childhood obesity in the developed world. While multifactorial in cause, a major factor is an increasingly sedentary lifestyle of children. Our research shows that a mixed reality system that is of interest to children can be a powerful motivator of healthy activity. We designed and constructed a mixed reality system that allowed children to exercise, play with, and train a virtual pet using their own physical activity as input. The health, happiness, and intelligence of each virtual pet grew as its associated child owner exercised more, reached goals, and interacted with their pet. We report results of a research study involving 61 children from a local summer camp that shows a large increase in recorded and observed activity, alongside observational evidence that the virtual pet was responsible for that change. These results, and the ease at which the system integrated into the camp environment, demonstrate the practical potential to impact the exercise behaviors of children with mixed reality.

    Despite much progress in the understanding of pathogenesis and of management, diarrhoeal illnesses remain one of the most important causes of global childhood mortality and morbidity. Infections account for most illnesses, with pathogens employing ingenious mechanisms to establish disease. In the developed world, an upsurge in immune-mediated gut disorders might have resulted from a disruption of normal bacterial-epithelial cross-talk and impaired maturation of the gut's immune system. Oral rehydration therapies are the mainstay of management of gastroenteritis, and their composition continues to improve. Malnutrition remains the major adverse prognostic indicator for diarrhoea-related mortality, emphasising the importance of nutrition in early management. Drugs are of little use, except for specific indications although new agents that target mechanisms of secretory diarrhoea show promise, as do probiotics. However, preventive strategies on a global scale might ultimately hold the greatest potential to reduce the burden of diarrhoeal disease. These strategies include vaccines and, most importantly, policies to address persisting inequalities between the developed and developing worlds with respect to nutrition, sanitation, and access to safe drinking water.

    2016-01-01

    Diarrhoea is one of the most commonly occurring diseases. This article presents a review of the current state of the treatment of acute infectious diarrhoea, as well as of the most important pathogens. The general principles of the therapy of diarrhoea are exemplified, followed by a description of the targeted antimicrobial therapy of the most important bacterial gastrointestinal infections, including salmonellosis, shigellosis and Campylobacter infections, as well as infections with pathogenic Escherichia coli strains, yersiniosis and cholera. Diarrhoea caused by toxigenic Clostridium difficile strains has increased in incidence and in severity. These infections will therefore be described in detail, including important new aspects of treatment. Symptomatic therapy is still the most important component of the treatment of infectious diarrhoea. However, empirical antibiotic therapy should be considered for severely ill patients with a high frequency of stools, fever, bloody diarrhoea, underlying immune deficiency, advanced age or significant comorbidities. Increasing resistance, in particular against fluoroquinolones, must be taken into consideration. Therapy with motility inhibitors is not recommended for Shiga toxin-producing Escherichia coli (STEC) infections, Clostridium difficile infections (CDI), and severe colitis. The macrocyclic antibiotic fidaxomicin can reduce the rate of recurrent disease in CDI. Furthermore, evidence for the benefits of faecal microbiota transplantation as a treatment option for multiple recurrences of CDI is increasing. In conclusion, the treatment of acute diarrhoea is still primarily supportive. General empirical antibiotic therapy for acute diarrhoea is not evidence-based.

    This study assessed whether an oral rehydration solution (ORS) in which glucose is replaced by L-glutamine (L-glutamine ORS) is more effective than the standard glucose-based rehydration solution recommended by the World Health Organization (WHO-ORS) in reducing the stool volume and time to rehydrate in acute diarrhoea. In a double-blind, randomized controlled trial in a Mexican hospital, 147 dehydrated children, aged 1–60 month(s), were assigned either to the WHO-ORS (74 children), or to the L-glutamine ORS (73 children) and followed until successful rehydration. There were no significant differences between the groups in stool output during the first four hours, time to successful rehydration, volume of ORS required for rehydration, urinary output, and vomiting. This was independent of rotavirus-associated infection. An L-glutamine-containing glucose-free ORS seems not to offer greater clinical benefit than the standard WHO-ORS in mildly-to-moderately-dehydrated children with acute non-cholera diarrhoea.

    There is an undeniable link between gastrointestinal disorders and malnutrition. Chronic diarrhoea is one of the most common gastrointestinal conditions that can impact a patient's nutritional status. The nutritional consequences will depend on the cause of the diarrhoea as well as the location and extent of gastrointestinal involvement. In general, malabsorption plays a central role in the interaction between malnutrition and chronic diarrhoea. Malabsorption can result in both nutritional deficits and diarrhoea. With severe malnutrition, chronic diarrhoea can persist due to impaired immune function and poor mucosal recovery. Food intolerance and an inappropriate diet in the setting of malabsorption may also contribute to chronic diarrhoea. Patients may attribute their gastrointestinal symptoms to specific dietary intake, which can lead to self-imposed indiscriminate dietary restrictions. Therefore, disease-specific treatment in conjunction with appropriate nutritional counselling and intervention is recommended in the prevention and treatment of malnutrition in patients with chronic diarrhoea. Specialized nutritional support through enteral or parenteral administration may be required to treat severe caloric and micronutrient deficiencies. In this review, we aim to summarize the mechanism, diagnosis, and treatment of the nutritional consequences of chronic diarrhoea.

    Research suggests that many children are exposed to adverse experiences in childhood. Such adverse childhood exposures may result in stress and trauma, which are associated with increased morbidity and mortality into adulthood. In general populations and trauma-exposed adults, mindfulness interventions have demonstrated reduced depression and anxiety, reduced trauma-related symptoms, enhanced coping and mood, and improved quality of life. Studies in children and youth also demonstrate that mindfulness interventions improve mental, behavioral, and physical outcomes. Taken together, this research suggests that high-quality, structured mindfulness instruction may mitigate the negative effects of stress and trauma related to adverse childhood exposures, improving short- and long-term outcomes, and potentially reducing poor health outcomes in adulthood. Future work is needed to optimize implementation of youth-based mindfulness programs and to study long-term outcomes into adulthood. PMID:28264496

    The human olfactory bulb (OB) is the first relay station of the olfactory pathway and may have the potential for postnatal neurogenesis in early childhood. In animals, chronic stress affects the OB and olfactory functioning. For humans, it has been shown that major depressive disorder is accompanied by reduced OB volume and reduced olfactory function. However, it is not clear if major stress in childhood development also affects olfactory functioning and OB volume in humans. OB volume was measured and olfactory function was tested in 17 depressive patients with and 10 without a history of severe childhood maltreatment (CM). CM patients exhibited a significantly reduced olfactory threshold and identification ability. The OB volume of the CM patients was significantly reduced to 80% of the non-CM patients. In conclusion, postnatal neurogenesis might be by reduced in CM, which may affect olfactory function of the brain in later life. Alternatively, a reduced OB volume may enhance psychological vulnerability in the presence of adverse childhood conditions although other areas not analyzed in this study may also be involved.

    With a systematically sampled population of children aged under 5 attending this centre for diarrhoeal disease research during 1983-5 a retrospective analysis of persistent diarrhoea (defined as greater than 14 days' duration) was performed to identify the possible risk factors for this syndrome. Of the 4155 children included in the analysis, 410 (10%) gave a history of persistent diarrhoea. A comparison with children with acute diarrhoea matched for age showed that 11 factors were correlated with persistent diarrhoea, and strongly associated factors were stools with blood or mucus, or both, lower respiratory tract infection, malnutrition, vitamin A deficiency, and antibiotic use before presentation. The peak age was 2 years, and there was no sex difference. Deaths occurred more often in the group with persistent diarrhoea. Although Shigella spp, Campylobacter jejuni, and Giardia lamblia were frequently identified, their rates of isolation were not significantly higher among patients with persistent diarrhoea. No seasonal variation was observed in the rates of persistent diarrhoea. Although the introduction of family food to the diet was associated with higher rates, this factor was difficult to separate from the age dependent risks.

    Laws and regulations are among the most effective mechanisms for getting large segments of the population to adopt safety behaviors. These have been applied at both the state and federal levels for diverse injury issues. Certain legal actions are taken to prevent the occurrence of an otherwise injury-producing event, while other legal actions are designed to prevent injury once an event has occurred. At the federal level, effective laws and regulations have been directed at dangers posed by unsafe manufactured products or motor vehicle design. At the state level, effective safety laws and regulations have been directed at encouraging safety behaviors and regulating the use of motor vehicles or other forms of transportation. In this article, six legislative efforts are described to point out pros and cons of the legislative approach to promoting safety. Three such efforts are aimed at preventing injury-producing events from occurring: mandating child-resistant packaging for prescription drugs and other hazardous substances, regulating tap water temperature by presetting a safe hot-water heater temperature at the factory, and graduated licensing. Three other examples illustrate the value and complexities of laws designed to prevent injuries once an injury-producing event does occur: mandatory bicycle helmet use, sleep-wear standards, and child safety seat use. This article concludes with specific recommendations, which include assessing the value of laws and regulations, preventing the rescission of laws and regulations known to work, refining existing laws to eliminate gaps in coverage, developing regulations to adapt to changing technology, exploring new legal means to encourage safe behavior, and increasing funding for basic and applied research and community programs. Further reductions in childhood injury rates will require that leaders working in the field of injury prevention together provide the creativity to devise new safety devices and programs, incentives

    -risk population showed significant reduction in mean episodes of diarrhoea (1.68 fewer) in the intervention group (Mean difference 1.68, 95% CI 1.93 to 1.43; one trial, 148 participants, moderate quality evidence). There was increase in hand washing frequency, seven times per day in the intervention group versus three times in the control in this hospital trial (one trial, 148 participants, moderate quality evidence). We found no trials evaluating or reporting the effects of hand washing promotions on diarrhoea-related deaths, all-cause-under five mortality, or costs. Authors' conclusions Hand washing promotion probably reduces diarrhoea episodes in both child day-care centres in high-income countries and among communities living in LMICs by about 30%. However, less is known about how to help people maintain hand washing habits in the longer term. PLAIN LANGUAGE SUMMARY Hand washing promotion for preventing diarrhoea Review question This Cochrane Review summarises trials evaluating the effects of promoting hand washing on the incidence of diarrhoea among children and adults in day-care centres, schools, communities, or hospitals. After searching for relevant trials up to 27 May 2015, we included 22 randomized controlled trials conducted in both high-income countries (HICs) and low- and middle-income countries (LMICs). These trials enrolled 69,309 children and 148 adults. How does hand washing prevent diarrhoea and how might hand washing be promoted Diarrhoea causes many deaths in children below five years of age, mostly in LMICs. The organisms causing diarrhoea are transmitted from person to person through food and water contaminated with faeces, or through person-to-person contact. Hand washing after defecation, or after cleaning a baby's bottom, and before preparing and eating food, can therefore reduce the risk of diarrhoea. Hand washing can be promoted through group or individual training on hygiene education, germ-health awareness, use of posters, leaflets, comic books

    Objectives: The role of zinc in the pathogenesis of diarrhoea is controversial. This study was conducted to compare serum zinc levels in children with acute diarrhoea to those found in healthy children. Methods: This case-control study was carried out at the Qazvin Children’s Hospital in Qazvin, Iran, between July 2012 and January 2013. A total of 60 children with acute diarrhoea (12 children with bloody diarrhoea and 48 children with watery diarrhoea) and 60 healthy children were included. Zinc levels for all subjects were measured using a flame atomic absorption spectrophotometer and data were analysed and compared between groups. Results: Mean serum zinc levels in the patients with acute bloody diarrhoea, acute watery diarrhoea and the control group were 74.1 ± 23.7 μg/dL, 169.4 ± 62.7 μg/dL and 190.1 ± 18.0 μg/dL, respectively (P = 0.01). Hypozincaemia was observed in 50.0% of children with acute bloody diarrhoea and 12.5% of those with acute watery diarrhoea. None of the patients in the control group had hypozincaemia (P = 0.01). Conclusion: Children with acute bloody diarrhoea had significantly reduced serum zinc levels in comparison to healthy children. However, a study with a larger sample size is needed to examine the significance of this trend. PMID:26629379

    Background Probiotic capsules have been shown to reduce the incidence of antibiotic-associated diarrhoea in a number of settings. If probiotic yogurt were equally efficacious then it would provide a simple and cost-effective means of preventing antibiotic-associated diarrhoea. Aim To investigate whether eating live bio yogurt at the time of taking oral antibiotics can prevent antibiotic-associated diarrhoea. Design of study This study was a three-arm (bio yogurt, commercial yogurt, no yogurt) randomised controlled trial with double blinding between the two yogurt arms. Setting A single primary care general practice surgery in Hingham, Norfolk. The study population included all ages except babies. Method Patients aged over 1 year who required a 1-week course of antibiotics were included in the study. There was complete follow up for 369 patients. The intervention was the consumption of 150 ml of live strawberry-flavoured yogurt for 12 days, starting on the first day of taking the antibiotic. Diarrhoea was defined as ‘three or more loose stools per day over at least 2 consecutive days’ within 12 days of starting the antibiotics. Results Of the 120 patients in the no-yogurt group, 17 (14%, 95% confidence interval [CI] = 9.0 to 21.5) developed diarrhoea. Of the 118 given commercial yogurt, 13 (11%, 95% CI =6.6 to 17.9) developed diarrhoea; nine of the 131 patients (7%; 95% CI = 3.7 to 12.5) given bio yogurt developed diarrhoea (P = 0.17). Conclusion Overall, this study failed to demonstrate that yogurt has any effect on antibiotic-associated diarrhoea. PMID:18252070

    Diarrhoea is a major impediment to profitable sheep production in many countries as it predisposes animals to blowfly strike and contaminates wool and meat carcasses. While it is accepted that nematode parasites are a major cause of diarrhoea in grazing animals, less is known about what facets of the host-parasite relationship lead to diarrhoea and what the most appropriate control strategies are. In this review, the relationship between gastrointestinal nematode infection and diarrhoea is discussed and it is concluded that in many cases, particularly in immunologically mature sheep, diarrhoea is not due to parasite infection per se but rather due to immunopathological processes. Mechanisms that lead to faecal softening in immune sheep are considered, and the question addressed as to whether anthelmintic treatment and selective breeding of naturally parasite-resistant sheep will effectively reduce the occurrence of diarrhoea.

 Clinical features and laboratory tests that determine carbohydrate in faeces were evaluated to determine which was best able to distinguish between osmotic and secretory diarrhoea in infants and children. For this purpose 80 boys aged 3 to 24 months, with acute watery diarrhoea, were studied prospectively. The faecal osmolar gap (FOG) was calculated as: serum osmolarity − [2 × (faecal sodium + potassium concentration)]. Fifty eight patients were classified as having predominantly osmotic diarrhoea (FOG >100 mosmol/l), and 22 as having predominantly secretory diarrhoea (FOG ⩽100 mosmol/l). The two groups were comparable in their clinical features on admission, in the results of blood and urine tests, and in the evolution of their diarrhoeal illness. Evidence of steatorrhoea (by positive Sudan III test) and of acid faecal pH on admission were significantly more frequent in patients with osmotic diarrhoea. Mean (SD) faecal osmolarity was not significantly different between the two groups (319 (80) mosmol/l in secretory diarrhoea v 361 (123) mosmol/l in osmotic diarrhoea). Tests for reducing substances in faeces such as Benedict's test—with and without hydrolysis—and glucose strip, all showed a positive and significant association with osmotic diarrhoea (p <0.05, <0.025, <0.05, respectively). The presence of excess reducing substances (Benedict's test with hydrolysis >++) on admission was the most sensitive and specific test with the best predictive value for differentiating between the two types of watery diarrhoea.

    The importance of diarrhoeagenic Escherichia coli (DEC) in Africa is poorly understood, and is unknown in Burkina Faso. This study investigated the occurrence of five major DEC pathogroups in primary cultures of stool samples from 658 Burkinabe children under 5 years old using 16-plex PCR for virulence-associated genes. At least one DEC pathogroup was detected in 45% of 471 children with diarrhoea and in 29% of 187 children without diarrhoea (p <0.001). More than one DEC pathogroup was detected in 11% of children with and 1% of children without diarrhoea (p <0.001). Enteroaggregative E. coli was the most common pathogroup in both children with diarrhoea (26%) and children without diarrhoea (21%). Enteropathogenic E. coli and enterotoxigenic E. coli were detected significantly more often in children with diarrhoea (16% and 13%) than in children without diarrhoea (5% and 4%; p <0.001 for both pathogroups). Shiga toxin-producing E. coli and enteroinvasive E. coli were detected only in children with diarrhoea (2% and 1%, respectively). Diarrhoeagenic E. coli, especially enteropathogenic and enterotoxigenic, may be important, unrecognized causes of childhood diarrhoea in Burkina Faso.

    Diarrhea and malnutrition represent leading causes of death for children in Mali. Understanding a community's needs and ideas are critical to ensure the success of prevention and treatment interventions for diarrheal disease, as well as to improve food security to help reduce malnutrition. The objective of this study was to incorporate the Community Readiness Model (CRM) for the issues of childhood diarrheal disease and food security in Mali to measure baseline community readiness prior to any program implementation. Thirteen key respondents residing in Dioro, Mali were selected based on varied social roles and demographics and completed two questionnaires on these public health issues. The overall readiness score to reduce childhood diarrheal disease was 5.75 ± 1.0 standard deviation (preparation stage). The overall readiness score to improve food security was 5.5 ± 0.5 standard deviation (preparation stage). The preparation stage indicates that at least some of the community have basic knowledge regarding these issues, and want to act locally to reduce childhood diarrhea and improve food security and nutrition. Proposed activities to increase community readiness on these issues are provided and are broad enough to allow opportunities to implement community- and culturally-specific activities by the Dioro community.

  7. Definitions, pathophysiology, and evaluation of chronic diarrhoea.

    PubMed

    Schiller, Lawrence R

    2012-10-01

    Definitions for 'chronic diarrhoea' are arbitrary and are not evidence-based. The duration of illness that would differentiate acute from chronic diarrhoea is often taken as four weeks and serves best to exclude most infectious causes of diarrhoea which run their courses within that time interval. Patients tend to identify loose stool consistency rather than increased frequency of bowel movements when they say that they have diarrhoea. Some patients complaining of diarrhoea have frequent passage of formed stools and some have fecal incontinence. It is incumbent on the treating physician to inquire exactly what is meant by diarrhoea by a given patient. The pathophysiology of diarrhoea is complex, but generally comes down to explaining why there is excess water in stools. This can result from impaired absorption, excess secretion or retention of intraluminal fluid due to osmotic forces generated by poorly absorbed substances. The evaluation of diarrhoea is challenging. An algorithmic approach is feasible.

    Despite the existence of low-cost and effective interventions for childhood pneumonia and diarrhoea, these conditions remain two of the leading killers of young children. Based on feedback from health professionals in countries with high child mortality, in 2009, WHO and Unicef began conceptualising an integrated approach for pneumonia and diarrhoea control. As part of this initiative, WHO and Unicef, with support from other partners, conducted a series of five workshops to facilitate the inclusion of coordinated actions for pneumonia and diarrhoea into the national health plans of 36 countries with high child mortality. This paper presents the findings from workshop and post-workshop follow-up activities and discusses the contribution of these findings to the development of the integrated Global Action Plan for the Prevention and Control of Pneumonia and Diarrhoea, which outlines the necessary actions for elimination of preventable child deaths from pneumonia and diarrhoea by 2025. Though this goal is ambitious, it is attainable through concerted efforts. By applying the lessons learned thus far and continuing to build upon them, and by leveraging existing political will and momentum for child survival, national governments and their supporting partners can ensure that preventable child deaths from pneumonia and diarrhoea are eventually eliminated.

    Protozoal infections of the gastrointestinal tract occur worldwide and have substantial morbidity and mortality. Prevalence is higher in the economically deprived regions of the world, especially the developing countries. Infections like amoebiasis and giardiasis have a worldwide distribution, being endemic in India. Apart from producing GI symptoms, growth and development of children is also impaired. It is seen that protozoa multiply rapidly in their hosts and as there is a lack of effective vaccines, chemotherapy has been the only practiced way to treat individuals and reduce transmission. The current treatment modalities for protozoal diarrhoea include 5-nitrosoimidazoles, iodoquinol, diloxanide furoate, paromomycin, chloroquine, and trimethoprim-sulphamethoxazole.

    In recent years, research into and public interest in probiotics and probiotic foods have risen. Lactobacilli and bifidobacterium are the most commonly used probiotics while yoghurt and kefir are popular foods containing probiotics. Probiotics have been used to manage diarrhoea. Many things cause diarrhoea, including bacterial, viral and protozoal infections, radiation and antibiotic therapy. Different studies have found that probiotics may also enhance the immune response, reduce serum cholesterol, prevent colonic cancer, prevent dental caries, prevent ulcers due to Helicobacter pylori, maintain urogenital health, and ameliorate hepatic encephalopathy. Further studies are required to establish their role in these conditions.

    Clostridium difficile is a well documented cause of antibiotic associated diarrhoea in hospitalised patients, but may account for only approximately 20% of all cases. This leader reviews the current knowledge and understanding of the pathogenesis, epidemiology, and diagnosis of non-food borne Clostridium perfringens diarrhoea. Although enterotoxigenic C perfringens has been implicated in some C difficile negative cases of antibiotic associated diarrhoea, C perfringens enterotoxin detection methods are not part of the routine laboratory investigation of such cases. Testing for C perfringens enterotoxin in faecal samples from patients with antibiotic associated diarrhoea and sporadic diarrhoea on a routine basis would have considerable resource implications. Therefore, criteria for initiating investigations and optimum laboratory tests need to be established. In addition, establishing the true burden of C perfringens antibiotic associated diarrhoea is important before optimum control and treatment measures can be defined.

The aim of this study was to identify the risk factors and to understand the management of acute diarrhoea. A pretested structured questionnaire was used for interviewing mothers of 440 children in a prospective, matched, case-control study at the University of Gondar Referral and Teaching Hospital in Gondar, Ethiopia. Results of multivariate analysis demonstrated that children who were breastfed and not completely weaned and mothers who were farmers were protective factors; risk factors for diarrhoea included sharing drinking-water and introducing supplemental foods. Children presented with acute diarrhoea for 3.9 days with 4.3 stools per day. Mothers usually did not increase breastmilk and other fluids during diarrhoea episodes and generally did not take children with diarrhoea to traditional healers. Incorporating messages about the prevention and treatment of acute diarrhoea into child-health interventions will help reduce morbidity and mortality associated with this disease.

    A common policy approach to reducing childhood obesity aims to shape the environment in which children spend most of their time: neighborhoods and schools. This paper uses richly detailed data on the body mass index (BMI) of all New York City public school students in grades K-8 to assess the potential for place-based approaches to reduce child obesity. We document variation in the prevalence of obesity across NYC public schools and census tracts, and then estimate the extent to which this variation can be explained by differences in individual-level predictors (such as race and household income). Both unadjusted and adjusted variability across neighborhoods and schools suggest place-based policies have the potential to meaningfully reduce child obesity, but under most realistic scenarios the improvement would be modest.

    An updated review of nonvaccine interventions for the prevention of childhood diarrhoea in developing countries is presented. The importance of various key preventive strategies (breast-feeding, water supply and sanitation improvements) is confirmed and certain aspects of others (promotion of personal and domestic hygiene, weaning education/food hygiene) are refined. Evidence is also presented to suggest that, subject to cost-effectiveness examination, two other strategies-vitamin A supplementation and the prevention of low birth weight-should be promoted to the first category of interventions, as classified by Feachem, i.e. those which are considered to have high effectiveness and strong feasibility.

    An obese diabetic male presented with self limiting diarrhoea of 1 day duration, which had started after he ate sausages. Examination was unrevealing except for persistent low blood pressure. Computed tomographic (CT) scan, done to rule out retroperitoneal bleed, incidentally showed air in the gall bladder. He underwent emergent cholecystectomy, and a gangrenous gall bladder that grew Clostridium perfringens was removed. Emphysematous cholecystitis is not so infrequent, although only rarely does it present as diarrhoea alone. A high index of clinical suspicion is necessary as even advanced presentation can be subtle and appropriate radio imaging essential. Although abdominal radiograph and ultrasound could be useful, a CT scan is diagnostic. The CT scan and its classical finding confirmed the diagnosis, and it reiterates the importance of timely identification and urgent action, as emphysematous cholecystitis is associated with high mortality.

    OBJECTIVE: More than 10 million children die each year mostly from preventable causes and particularly in developing countries. WHO guidelines for the Integrated Management of Childhood Illness (IMCI) are intended to reduce childhood mortality and are being implemented in Ethiopia. As well as specific clinical interventions, the role of the community in understanding and acting on childhood sickness is an important factor in improving survival. This trial sought to assess the effect on survival of community-based health promotion activities. METHODS: Two districts in northern Ethiopia were studied, each with a random sample of more than 4000 children less than 5 years old. Regular six-monthly visits were made to document deaths among children. After the first year, communities in one district were educated about issues of good childcare and caring for sick children while the other district received this information only after the trial ended. FINDINGS: Although overall mortality was higher in the post-intervention period, most of the increase was seen in the control area. A Cox proportional hazards model gave an adjusted hazard ratio of 0.66 (95% confidence interval = 0.46-0.95) for the intervention area compared with the control area in the post-intervention period, with no significant pre-intervention difference. Significant survival advantages were found for females, children of younger fathers, those with married parents, those living in larger households, and those whose nearest health facility was a health centre. For all of the children who died, only 44% of parents or caregivers had sought health care before the child's death. CONCLUSION: This non-specific community-based public health intervention, as an addition to IMCI strategies in local health facilities, appears to have significantly reduced childhood mortality in these communities. The possibility that such interventions may not effectively reach certain social groups (for example single parents) is

    The World Health Organization (WHO) guidelines for diagnosis of pneumonia are based on the history of cough or difficult breathing and age-adjusted respiration rates. Metabolic acidosis associated with dehydrating diarrhoea also influences the respiration rate. Two hundred and four children, aged 2 to 59 months, with dehydrating diarrhoea and a history of cough and/or fast breathing, were enrolled in a prospective study. Pneumonia diagnoses were made on enrollment and again 6 hours post-enrollment (after initial rehydration), using the WHO guidelines. These were compared with investigators' clinical diagnosis based on history and findings of physical examination and a chest x-ray at the same time points. Using the WHO guidelines, 149/152 (98%) infants in the 2-11 months age-group and 38/40 (95%) children in the 12-59 months age-group were diagnosed to have pneumonia on enrollment, which dropped to 107 (70%) and 30 (75%) respectively at 6 hours post-enrollment. The specificity of the WHO guidelines for diagnosis of pneumonia was very low (6.9%) at enrollment but increased to 65.5% at 6 hours post-enrollment, after initial rehydration. The specificity of the WHO guidelines for diagnosis of pneumonia in young children is significantly reduced in dehydrating diarrhoea. For young children with dehydrating diarrhoea, rehydration, clinical and radiological assessments are useful in identifying those with true pneumonia.

    Diarrhoea induced by chemotherapy in cancer patients is common, causes notable morbidity and mortality, and is managed inconsistently. Previous management guidelines were based on poor evidence and neglect physiological causes of chemotherapy-induced diarrhoea. In the absence of level 1 evidence from randomised controlled trials, we developed practical guidance for clinicians based on a literature review by a multidisciplinary team of clinical oncologists, dietitians, gastroenterologists, medical oncologists, nurses, pharmacist, and a surgeon. Education of patients and their carers about the risks associated with, and management of, chemotherapy-induced diarrhoea is the foundation for optimum treatment of toxic effects. Adequate--and, if necessary, repeated--assessment, appropriate use of loperamide, and knowledge of fluid resuscitation requirements of affected patients is the second crucial step. Use of octreotide and seeking specialist advice early for patients who do not respond to treatment will reduce morbidity and mortality. In view of the burden of chemotherapy-induced diarrhoea, appropriate multidisciplinary research to assess meaningful endpoints is urgently required.

    unimproved water sources (30 studies) and unimproved or unclear sanitation (34 studies). The primary outcome in most studies was self-reported diarrhoea, which is at high risk of bias due to the lack of blinding in over 80% of the included studies. Source-based water quality improvements There is currently insufficient evidence to know if source-based improvements such as protected wells, communal tap stands, or chlorination/filtration of community sources consistently reduce diarrhoea (one cluster-RCT, five CBA studies, very low quality evidence). We found no studies evaluating reliable piped-in water supplies delivered to households. Point-of-use water quality interventions On average, distributing water disinfection products for use at the household level may reduce diarrhoea by around one quarter (Home chlorination products: RR 0.77, 95% CI 0.65 to 0.91; 14 trials, 30,746 participants, low quality evidence; flocculation and disinfection sachets: RR 0.69, 95% CI 0.58 to 0.82, four trials, 11,788 participants, moderate quality evidence). However, there was substantial heterogeneity in the size of the effect estimates between individual studies. Point-of-use filtration systems probably reduce diarrhoea by around a half (RR 0.48, 95% CI 0.38 to 0.59, 18 trials, 15,582 participants, moderate quality evidence). Important reductions in diarrhoea episodes were shown with ceramic filters, biosand systems and LifeStraw® filters; (Ceramic: RR 0.39, 95% CI 0.28 to 0.53; eight trials, 5763 participants, moderate quality evidence; Biosand: RR 0.47, 95% CI 0.39 to 0.57; four trials, 5504 participants, moderate quality evidence; LifeStraw®: RR 0.69, 95% CI 0.51 to 0.93; three trials, 3259 participants, low quality evidence). Plumbed in filters have only been evaluated in high-income settings (RR 0.81, 95% CI 0.71 to 0.94, three trials, 1056 participants, fixed effects model).

    By conducting a case-control study in two university hospitals, we explored the association between modifiable risk behaviours and diarrhoea. Children aged <5 years attending outpatient clinics for diarrhoea were matched by age and sex with controls. Data were collected on family demographics, socioeconomic indicators, and risk behaviour practices. Two rectal swabs and a stool specimen were collected from cases and controls. Samples were cultured for bacterial pathogens using standard techniques and tested by ELISA to detect rotavirus and Cryptosporidium spp. Four hundred cases and controls were enrolled between 2007 and 2009. The strongest independent risk factors for diarrhoea were: presence of another household member with diarrhoea [matched odds ratio (mOR) 4.9, 95% CI 2.8-8.4] in the week preceding the survey, introduction to a new kind of food (mOR 3, 95% CI 1.7-5.4), and the child being cared for outside home (mOR 2.6, 95% CI 1.3-5.2). While these risk factors are not identifiable, in some age groups more easily modifiable risk factors were identified including: having no soap for handwashing (mOR 6.3, 95% CI 1.2-33.9) for children aged 7-12 months, and pacifier use (mOR 1.9, 95% CI 1.0-3.5) in children aged 0-6 months. In total, the findings of this study suggest that community-based interventions to improve practices related to sanitation and hygiene, handwashing and food could be utilized to reduce the burden of diarrhoea in Egyptian children aged <5 years.

    A 6-month survey of diarrhoeas in Vietnamese refugee camp children was carried out and was responsible for 32.5% of pediatric consultations. One hundred twenty cases were studied and underwent laboratory work-up. Peak incidence was in the 4-6 years. Diarrhoea was observed to be at its peak in April and June which coincides with the increase in the number of transients and with the rainy season. Diarrhoea with fever and abdominal pain were the most prominent clinical symptoms. Only 8.3% grew bacterial pathogens' enteropathogenic E. coli being the most common followed by Staphylococcus aureus. It is apparent that a causative agent other than a bacterial pathogen such as a virus may play a major role in diarrhoeas in Vietnamese refugee infants and children. The lack of environmental sanitation and health education play a major role in the causation of diarrhoea in these refugee children.

    Objective Early childhood caries (ECC) is a serious and preventable disease which pediatric clinicians can help address by counseling to reduce risk. Research Design We implemented a multifaceted practice-based intervention in a pediatric outpatient clinic treating children vulnerable to ECC (N = 635), comparing results to those from a similar nearby clinic providing usual care (N = 452). Intervention We provided communication skills training using the approach of patient centered counseling, edited the electronic medical record to prompt counseling, and provided parents/caregivers with an educational brochure. Outcome Measures We assessed changes in provider knowledge about ECC after the intervention, and examined providers' counseling practices and incidence of ECC over time by site, controlling for baseline ECC, patient sociodemographics and parents'/caregivers' practice of risk factors (diet, oral hygiene, tooth-monitoring), among 1045 children with complete data. Results Provider knowledge about ECC increased after the intervention training (percentage correct answers improved from 66% to 79%). Providers at the intervention site used more counseling strategies, which persisted after adjustment for sociodemographic characteristics. Children at the intervention site had a 77% reduction in risk for developing ECC at follow up, after controlling for age and race/ethnicity, sociodemographics and ECC risk factors; P ≤ 0.004. Conclusions The multifaceted intervention was associated with increased provider knowledge and counseling, and significantly attenuated incidence of ECC. If validated by additional studies, similar interventions could have the potential to make a significant public health impact on reducing ECC among young children. PMID:19786919

    Background Allergy has sharply increased in affluent Western countries in the last 30 years. N-3 long chain polyunsaturated fatty acids (n-3 LCPUFAs) may protect the immune system against development of allergy. Methods We prospectively categorized illnesses by body system in a subset of 91 children from the Kansas City cohort of the DIAMOND (DHA Intake and Measurement of Neural Development) study who had yearly medical records through 4 years of age. As infants, they were fed either a control formula without LCPUFA (n=19) or one of three formulas with LCPUFA from docosahexaenoic acid (DHA) and arachidonic acid (ARA) (n=72). Results Allergic illnesses in the first year were lower in the combined LCPUFA group compared to the control. LCPUFAs significantly delayed time to first allergic illness (p=0.04) and skin allergic illness (p=0.03); and resulted in a trend to reduced wheeze/asthma (p=0.1). If the mother had no allergies, LCPUFAs reduced the risk of any allergic diseases (HR = 0.24, 95% CI = 0.1, 0.56, p=0.0.001) and skin allergic diseases (HR = 0.35, 95% CI = 0.13, 0.93, p=0.04). In contrast, if the mother had allergies, LCPUFAs reduced wheezing/asthma (HR = 0.26, 95% CI = 0.07, 0.9, p = 0.02). Conclusions LCPUFA supplementation during infancy reduced the risk of skin and respiratory allergic diseases in childhood with effects influenced by maternal allergies. PMID:26613373

  10. Enteral-tube-feeding diarrhoea: manipulating the colonic microbiota with probiotics and prebiotics.

    PubMed

    Whelan, Kevin

    2007-08-01

    Diarrhoea is a common and serious complication of enteral tube feeding. Its pathogenesis involves antibiotic prescription, enteropathogenic colonization and abnormal colonic responses, all of which involve an interaction with the colonic microbiota. Alterations in the colonic microbiota have been identified in patients receiving enteral tube feeding and these changes may be associated with the incidence of diarrhoea. Preventing negative alterations in the colonic microbiota has therefore been investigated as a method of reducing the incidence of diarrhoea. Probiotics and prebiotics may be effective because of their suppression of enteropathogenic colonization, stimulation of immune function and modulation of colonic metabolism. Randomized controlled trials of probiotics have produced contrasting results, although Saccharomyces boulardii has been shown to reduce the incidence of diarrhoea in patients in the intensive care unit receiving enteral tube feeding. Prebiotic fructo-oligosaccharides have been shown to increase the concentration of faecal bifidobacteria in healthy subjects consuming enteral formula, although this finding has not yet been confirmed in patients receiving enteral tube feeding. Furthermore, there are no clinical trials investigating the effect of a prebiotic alone on the incidence of diarrhoea. Further trials of the efficacy of probiotics and prebiotics, alone and in combination, in preventing diarrhoea in this patient group are warranted.

In 5 of the 6 operated group, surgery was followed by a striking cessation of the diarrhoea and with weight gain. It is concluded that (1) latent otomastoiditis may be a perpetuating factor in intractable diarrhoea; (2) myringotomy-antrotomy should be considered if other forms of treatment have failed, and especially if there is leucocytosis; (3) mastoiditis with diffuse osteitis seems to be associated with a poor prognosis.

    Advances in biology are providing deeper insights into how early experiences are built into the body with lasting effects on learning, behavior, and health. Numerous evaluations of interventions for young children facing adversity have demonstrated multiple, positive effects but they have been highly variable and difficult to sustain or scale. New research on plasticity and critical periods in development, increasing understanding of how gene-environment interaction affects variation in stress susceptibility and resilience, and the emerging availability of measures of toxic stress effects that are sensitive to intervention provide much-needed fuel for science-informed innovation in the early childhood arena. This growing knowledge base suggests 4 shifts in thinking about policy and practice: (1) early experiences affect lifelong health, not just learning; (2) healthy brain development requires protection from toxic stress, not just enrichment; (3) achieving breakthrough outcomes for young children facing adversity requires supporting the adults who care for them to transform their own lives; and (4) more effective interventions are needed in the prenatal period and first 3 years after birth for the most disadvantaged children and families. The time has come to leverage 21st-century science to catalyze the design, testing, and scaling of more powerful approaches for reducing lifelong disease by mitigating the effects of early adversity.

  16. Octreotide in the treatment of refractory diarrhoea and intestinal fistulae.

    PubMed Central

    Farthing, M J

    1994-01-01

    Persistent, refractory diarrhoea continues to be an important clinical problem. The mechanisms involved are associated with reduced intestinal absorption and increased intestinal secretion. Reduced intestinal absorption can result from small intestinal resection or from disorders in which there is damage to the small intestine. Motility disorders may also impair absorptive function. The rationale for using octreotide in refractory diarrhoea, intestinal motility disorders, and fistulae relates to its ability to promote intestinal absorption and inhibit gastric, pancreatic, and intestinal secretion. Several clinical studies in patients with short bowel syndrome have reported a reduction of intestinal output in patients taking octreotide compared with controls. Additionally, a number of studies have shown that octreotide improves secretory diarrhoea resulting from neuroendocrine tumours, intestinal infections in AIDS patients, and intestinal graft v host disease. Octreotide may be of use in patients suffering from intestinal motility disorders such as those associated with systemic sclerosis. Octreotide may also be of value in promoting closure of gastrointestinal and pancreatic fistulae. PMID:8206397

    Rotavirus is an important cause of childhood diarrhoea. A monovalent rotavirus vaccine (Rotarix®) was introduced into the Immunization Program of Brazil in 2006. In this study, we describe the incidence and burden of disease of rotavirus diarrhoea in two cohorts of children (vaccinated and unvaccinated). We followed two groups of 250 children under one year old, who were enrolled in December 2006 from a low-income residential area in Northeast Brazil. The children were monitored every two weeks for two years. Stool samples from children with diarrhoea were examined for the presence of rotavirus. Rotaviruses were genotyped using real time-polymerase chain reaction. The mean numbers of all-cause diarrhoea episodes/child (adjusted for age) in the first year were 0.87 and 0.84, in vaccinated and unvaccinated children, respectively. During the second year, the number of episodes/child decreased to 0.52 and 0.42. Only 16 (4.9%) of 330 stool samples were rotavirus-positive (10 vaccinated and 6 unvaccinated children) and only P[4]G2 rotaviruses were identified. All-cause diarrhoea episodes were more severe in unvaccinated children in the first year of age (p < 0.05), while vaccinated children had more severe episodes 18 months after vaccination. Rotavirus diarrhoea incidence was very low in both groups.

    2012-10-01

    The aetiology of diarrhoea can often be simple to identify, but in some cases may pose a challenge. The diagnosis of drug-induced diarrhoea can easily be sorted based on timing of the symptom with onset of a new drug. Treatment can vary from simply monitoring and eventual resolution with continuation of the drug, to discontinuation of the offending agent. In cases where a drug cannot always be stopped, additional medications can help control the symptom. Factitious diarrhoea can present a diagnostic challenge if the evaluating physician does not suspect its possibility. Typically a careful history, and in some cases, stool testing can provide clues. The diagnosis of idiopathic diarrhoea is often made when exhaustive testing provides no definite aetiology and the goal of management is supportive care and symptomatic treatment.

    Childhood obesity is epidemic in the United States, and is expected to increase the rates of many chronic diseases. Increasing physical activity and improving nutrition are keys to obesity prevention and control. But changing individual behavior is difficult. A comprehensive, coordinated strategy is needed. Policy interventions that make healthy dietary and activity choices easier are likely to achieve the greatest benefits. There is emerging evidence on how to address childhood obesity, but we must take action now to begin to reverse the epidemic.

    Infectious diarrhoea is a syndrome caused by a variety of bacterial, viral and parasitic organisms which represents a major cause of morbidity and mortality all over the world. The wide diversity of etiological agents impairs the surveillance and the diagnosis and affects the correct treatment applied to reduce the long-term complications. Besides well known enteric pathogens such as Salmonella, Shigella and Yersinia, a high number of emergent and re-emergent aetiologies are now recognised to be at the origin of diarrhoea. The lack of a correct diagnostic algorithm and adequate methods of analyses leads to under-evaluation and incertitude in an important number of clinical cases. Our study was designed as a complex analysis of the stool specimens collected from the patients, in the purpose to improve the laboratory diagnostic and to enhance the number of confirmed cases of infectious diarrhoea. A number of 756 samples from inpatients with diarrhoea were tested targeting pathogenic and opportunistic bacteria, viruses and parasites by classical and molecular methods. We documented that, in case of non-Salmonella, non-Shigella, non-Yersinia diarrhoea, the quality of diagnostic was improved by increasing the percentage of positive specimens to 22.49% compared to 11.12% when only bacteria, 5.56% when only viruses and 4.10% when only parasites were investigated. The laboratory data are of great value in evaluating the diarrhoea syndrome offering the documentation for an accurate epidemiological response and an adequate treatment.

    The protective effect of breastfeeding against infantile diarrhoea may be less pronounced in areas with modern water supply and sanitation facilities. This finding raises the question whether protection by breastfeeding against infantile diarrhoea in developing countries will decline with improvement in water supply and sanitation. To address this question a historical cohort study of the associations between feeding modes and diarrhoea incidence and severity in children aged 0-14 months at baseline was done in Al Ain city, United Arab Emirates. In this city in a newly developed country, modern water supply and sanitation facilities have become available to everyone during the last two decades. During three months of follow-up of 249 children, the nonbreastfed had more diarrhoea than did the partly breastfed, who in turn had more diarrhoea than did the fully breastfed. After multivariate adjustment, this dose-response effect was consistent for three measures of diarrhoeal morbidity in each child: occurrence or non-occurrence of incidence episodes, number of episodes, and total severity score. However, significant differences were seen only between the nonbreastfed and fully breastfed subgroups. These results indicate that in Al Ain, despite the universal access to modern water supply and sanitation facilities, breastfeeding plays an important role in reducing the incidence and severity of infantile diarrhoea. This observation is particularly important given the growing concern that, as an unwanted effect of 'modernisation', breastfeeding is on the decline in Al Ain and comparable populations elsewhere.

    While nutritional, microbiological and immunological factors have been implicated in childhood diarrhoea in many countries, there is limited aetiological information in Morogoro Region of Tanzania. A case-control study was conducted to establish whether diarrhoea in 6-60 months old children admitted at a Regional Hospital in Morogoro, was attributable to enteric bacteria and/or parasites and the contribution of under-nutrition, as measured by weight-for-age below -2 SD. From January to September 2011, children admitted at the Hospital with (cases) and without diarrhoea (controls), were obtained by convenience sampling. Children's stool, weights, ages and information on socioeconomic, feeding, water and sanitation factors were obtained. Stool samples were analysed for Escherichia coli O157, Shigella dysentriae, Campylobacter jejuni, Salmonella species and enteric parasites. Logistic regression was used to identify their association with diarrhoea occurrence; and survival analysis used to assess associated risk, using associated-hazard ratios (HR). Commonest bacteria isolated were Salmonella, more from controls, 45 (29.6%), than cases, 25 (16.6%); S. dysentriae and C. jejuni were only isolated from cases, while E coli O157 was not found. Enteric parasites were least prevalent; 4 (2.6%) for cases and 2 (1.3%) for controls. Although under-weight children had 38% increased risk of having diarrhoea than normal ones, this was not significant (HR = 0.98, p=0.928). Other factors found to significantly. (p<0.05) influence diarrhoea occurrence included age when breastfeeding stopped, food(s) given, feeding utensils and the child's toilet. In conclusion, childhood diarrhoea occurrence should warrant microbiological testing, for timely, appropriate treatment and prevention of transmission to others. Prevention and control measures for diarrhoea in children in Morogoro should include adequate breastfeeding, proper disposal of children's faeces and feeding children using cups

    Background Diarrhoea is a major health problem for children worldwide, accounting for 5–8 million deaths each year. Arque-Ajeeb (AA) is a compound formulation of Unani medicine. It is reputed for its beneficial effects in the treatment of diarrhoea and cholera, but the claim of its efficacy is yet to be tested. Therefore the present study has been planned to investigate the real efficacy of this drug in rats. Methods The effect of Arque-Ajeeb was investigated for antidiarrhoeal activity against charcoal-induced gut transit, serotonin-induced diarrhoea and PGE2-induced small intestine enteropooling in rats. The control, standard and test groups of experimental animals were administered with normal saline (p.o.), diphenoxylate hydrochloride (5 mg/kg, p.o.) and Arque-Ajeeb (0.07 ml and 0.14 ml/kg, p.o.) respectively except the control group of PGE2-induced small intestine enteropooling which received only 5% ethanol in normal saline (i.p.). Charcoal (10 ml/kg, p.o.) and serotonin (600 μg/kg, i.p.) were administered after 30 min, while PGE2 (100 μg/kg, p.o.) was administered immediately afterwards. The distance traveled by charcoal in small intestine was measured after 15 and 30 min of charcoal administration, diarrhoea was observed every 30-min for six hour after serotonin administration and the volume of intestinal fluid was measured after 30 min of PGE2 administration. Results Arque-Ajeeb (0.07 ml and 0.14 ml/kg) significantly inhibited the frequency of defaecation and decreased the propulsion of charcoal meal through the gastrointestinal tract, reduced the wetness of faecal droppings in serotonin-induced diarrhoea and also reduced the PGE2-induced small intestine enteropooling. Conclusion Arque-Ajeeb may have potential to reduce the diarrhoea in rats. Thus the drug may prove to be an alternate remedy in diarrhoea. PMID:15238156

    The bacterial pathogen most commonly associated with endemic forms of childhood diarrhoea is Escherichia coli . Studies of epidemiological characteristics of HEp-2 cell-adherent E. coli in diarrhoeal disease are required, particularly in developing countries. The aim of this study was evaluate the presence and significance of adherent Escherichia coli from diarrhoeal disease in children. The prevalence of LA, AA, and DA adherence patterns were determined in HEp-2 cells, the presence of virulence genes and the presence of the O serogroups in samples obtained from 470 children with acute diarrhoea and 407 controls in Porto Velho, Rondônia, Brazil. E. coli isolates were identified by PCR specific for groups of adherent E. coli . Out of 1,156 isolates obtained, 128 (11.0%) were positive for eae genes corresponding to EPEC, however only 38 (29.6%) of these amplified bfpA gene . EAEC were isolated from 164 (14.1%) samples; of those 41(25%), 32 (19%) and 16 (9.7%) amplified eagg , aggA or aafA genes, respectively and aggA was significantly associated with diarrhoea ( P = 0.00006). DAEC identified by their adhesion pattern and there were few isolates. In conclusion, EAEC was the main cause of diarrhoea in children, especially when the aggA gene was present, followed by EPEC and with a negligible presence of DAEC.

    Acute diarrhoea is a major health problem in many parts of the world, contributing to about 1.8 million deaths globally. The objectives of the study were to assess the incidence, determinants, and severity of acute diarrhoea in the population. A nation-wide cross-sectional survey involving about 57,000 respondents was conducted via face-to-face interview among eligible respondents of all ages. An acute diarrhoeal episode was defined as having three or more episodes of loose stools in any 24-hour period within the past four weeks before the interview. The severity was measured by duration of acute diarrhoea and associated symptoms. The variables tested as determinants were age, sex, ethnicity, the highest educational level, total monthly household income, and locality. Univariate, bivariate and multivariate procedures meant for complex study design were used in the analyses. The four-week incidence of acute diarrhoea was 5% [95% confidence interval (CI) 4.8-5.2]. The incidence of acute diarrhoea among the estimated population was the highest among young adults aged 20-29 years, Other Bumiputras (the pre-dominant ethnic group in East Malaysia), those with tertiary-level of education, those earning a monthly household income of less than RM 400, and rural dwellers. Only age, ethnicity, the highest level of education attained, and locality were significantly associated with acute diarrhoea in bivariate analysis. In multivariate analysis, these four variables were found to be the determinants of acute diarrhoea. Sex and monthly household income were excluded from the model. The mean duration of acute diarrhoea was 2.0 days (standard deviation 1.3). Forty-six percent of the respondents reported stomach cramps as an associated symptom. The findings revealed that acute diarrhoea is still a major public-health concern in Malaysia and grossly under-notified. There is a need for intensification of public-health intervention efforts to reduce the incidence of acute diarrhoea

    This study investigated the diarrhoea seasonality and its potential drivers as well as potential opportunities for future diarrhoea control and prevention in China. Data on weekly infectious diarrhoea cases in 31 provinces of China from 2005 to 2012, and data on demographic and geographic characteristics, as well as climatic factors, were complied. A cosinor function combined with a Poisson regression was used to calculate the three seasonal parameters of diarrhoea in different provinces. Regression tree analysis was used to identify the predictors of diarrhoea seasonality. Diarrhoea cases in China showed a bimodal distribution. Diarrhoea in children <5 years was more likely to peak in fall-winter seasons, while diarrhoea in persons > = 5 years peaked in summer. Latitude was significantly associated with spatial pattern of diarrhoea seasonality, with peak and trough times occurring earlier at high latitudes (northern areas), and later at low latitudes (southern areas). The annual amplitudes of diarrhoea in persons > = 5 years increased with latitude (r = 0.62, P<0.001). Latitude 27.8° N and 38.65° N were the latitudinal thresholds for diarrhoea seasonality in China. Regional-specific diarrhoea control and prevention strategies may be optimal for China. More attention should be paid to diarrhoea in children <5 years during fall-winter seasons.

  10. Brief oral health promotion intervention among parents of young children to reduce early childhood dental decay

    2013-01-01

    Background Severe untreated dental decay affects a child’s growth, body weight, quality of life as well as cognitive development, and the effects extend beyond the child to the family, the community and the health care system. Early health behavioural factors, including dietary practices and eating patterns, can play a major role in the initiation and development of oral diseases, particularly dental caries. The parent/caregiver, usually the mother, has a critical role in the adoption of protective health care behaviours and parental feeding practices strongly influence children’s eating behaviours. This study will test if an early oral health promotion intervention through the use of brief motivational interviewing (MI) and anticipatory guidance (AG) approaches can reduce the incidence of early childhood dental decay and obesity. Methods The study will be a randomised controlled study with parents and their new-born child/ren who are seen at 6–12 weeks of age by a child/community health nurse. Consenting parents will complete a questionnaire on oral health knowledge, behaviours, self-efficacy, oral health fatalism, parenting stress, prenatal and peri-natal health and socio-demographic factors at study commencement and at 12 and 36 months. Each child–parent pair will be allocated to an intervention or a standard care group, using a computer-generated random blocks. The standard group will be managed through the standard early oral health screening program; “lift the lip”. The intervention group will be provided with tailored oral health counselling by oral health consultants trained in MI and AG. Participating children will be examined at 24, and 36 months for the occurrence of dental decay and have their height and weight recorded. Dietary information obtained from a food frequency chart will be used to determine food and dietary patterns. Data analysis will use intention to treat and per protocol analysis and will use tests of independent

    Urinary tract infection (UTI) is common in children aged <5 years with diarrhoea, but little is known about risk factors, aetiology and outcome of such children. We aimed to evaluate these knowledge gaps of UTI in children aged <5 years with diarrhoea. We enrolled all children aged <5 years with diarrhoea admitted to Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh, between May 2011 and April 2013, who had history of fever (⩾38 °C) and obtained a urine sample for culture. Diarrhoea with UTI (confirmed by culture) constituted cases (n = 26) and those without UTI constituted controls (n = 78). Threefold controls were randomly selected. The case-fatality rate was comparable in cases and controls (4% vs. 1%, P = 0·439). Escherichia coli (69%) and Klebsiella (15%) were the most commonly isolated pathogens. Persistent diarrhoea, pneumonia and prior antibiotics use were identified as risk factors for UTI in logistic regression analysis (P < 0·05 for all). Thus, children with diarrhoea presenting with persistent diarrhoea, pneumonia, and prior antibiotic use should be investigated for UTI for their prompt management that may reduce morbidity.

    Rapid progress towards the development of rotavirus vaccines has prompted a reassessment of the disease burden of rotavirus diarrhoea in developing countries and the possible impact of these vaccines in reducing diarrhoeal morbidity and mortality among infants and young children. We examined the epidemiology and disease burden of rotavirus diarrhoea among hospitalized and clinic patients in African countries through a review of 43 published studies of the etiology of diarrhoea. The studies were carried out from 1975 through 1992, and only those in which a sample of more than 100 patients with diarrhoea were specifically screened for rotavirus by using an established diagnostic test were included. Rotavirus was detected in a median of 24% of children hospitalized for diarrhoea and in 23% who were treated as outpatients; 38% of the hospitalized patients with rotavirus were < 6 months and 81% were < 1 year of age. Rotavirus was detected year-round in nearly every country and generally exhibited distinct seasonal peaks during the dry months. In 5 countries where rotavirus strains had been G-typed, 74% of strains were of one of the four common serotypes (G1 to G4), G1 was the predominant serotype, and 26% were non-typeable. This cumulative experience from 15 African countries suggests that rotavirus is the most important cause of severe diarrhoea in African children and that most strains in circulation today belong to common G types that are included in reassortant vaccines. Wherever large numbers of cases of rotavirus diarrhoea occur early in infancy, immunization at birth may protect the children before their first symptomatic infection. PMID:9868844

    Twenty patients with persistent diarrhoea participated in a randomised, double-blind trial of oral sodium cromoglycate and placebo. Eight patients noted significant improvement in their diarrhoea while taking sodium cromoglycate and this did not correlate with the presence of other atopic diseases, a history of food intolerance, or the presence of lactase deficiency. The results suggest that some patients with diarrhoea of unknown cause may have food allergy as a major contributing cause for their diarrhoea. PMID:6777263

    Diarrhoeal diseases are a major problem in developing countries. Though precise data on childhood mortality associated with diarrhoeal diseases in Nepal are not available, it has been estimated that approximately 25 % of child deaths are associated with diarrhoeal disease, particularly acute diarrhoea. The purpose of this study was to assess the incidence of rotavirus causing acute diarrhoea in children less than 5 years of age. A total of 525 children with acute diarrhoea in a children's hospital of Kathmandu, Nepal, were enrolled between April and September 2011. The incidence of acute diarrhoea due to rotavirus was 25.9 % (136/525) as determined by ELISA. The percentage of rotavirus-infected males was higher (64.5 %) than females (35.5 %). The frequency of rotavirus cases was higher in children less than 2 years of age, among which the majority of cases (80.2 %) were in children between 6 and 24 months old (P<0.01). Genotypic characterization by RT-PCR revealed that the serotype G12 represented 55.9 % of cases in this study associated with P-types of either P[6], P[4] or P[8]. Further to this, a total of eight G/P combinations were identified, G12P[6] being the most common strain type of rotavirus in Nepal, with a prevalence rate of 46.4 %. The aim of this study was to find out the major genotypes of rotavirus causing acute diarrhoea in children.

    The ability of feed related measures to prevent or reduce post weaning diarrhoea (PWD) was examined in a split litter study including 30 pigs from 6 litters allotted into 5 groups. Four groups were exposed to 3 pathogenic strains of E. coli via the environment at weaning. Three of them were given zinc oxide, lactose+fibres or non-pathogenic strains of E. coli as probiotics. The challenged and the unchallenged control groups were given a standard creep feed. Diarrhoea was observed in all challenged groups but not among uninfected animals, and the incidence of diarrhoea was lower in the group given non-pathogenic E. coli compared to all other challenged groups. The severity of PWD also differed between litters. When corrected for mortality due to PWD, a decreased incidence of diarrhoea was also seen in the groups given zinc oxide or lactose+fibres. The dominating serotype of E. coli within faecal samples varied from day to day, also among diarrhoeic pigs, indicating that diarrhoea was not induced by one single serotype alone. The diversity of the faecal coliform populations decreased in all piglets during the first week post weaning, coinciding with an increased similarity between these populations among pigs in the challenged groups. This indicated an influence of the challenge strains, which ceased during the second week. The group given lactose+fibres was least affected with respect to these parameters. In conclusion feed related measures may alleviate symptoms of PWD. PMID:12831176

    Diarrhoea is one of leading causes of morbidity and mortality worldwide. Recent estimations suggested the number of deaths is close to 2.5 million. This study examined the causative agents of diarrhoea in children under 5 years of age in suburban areas of Khartoum, Sudan. A total of 437 stool samples obtained from children with diarrhoea were examined by culture and PCR for bacteria, by microscopy and PCR for parasites and by immunoassay for detection of rotavirus A. Of the 437 samples analysed, 211 (48%) tested positive for diarrhoeagenic Escherichia coli, 96 (22%) for rotavirus A, 36 (8%) for Shigella spp., 17 (4%) for Salmonella spp., 8 (2%) for Campylobacter spp., 47 (11%) for Giardia intestinalis and 22 (5%) for Entamoeba histolytica. All isolates of E. coli (211, 100 %) and Salmonella (17, 100%), and 30 (83%) isolates of Shigella were sensitive to chloramphenicol; 17 (100%) isolates of Salmonella, 200 (94%) isolates of E. coli and (78%) 28 isolates of Shigella spp. were sensitive to gentamicin. In contrast, resistance to ampicillin was demonstrated in 100 (47%) isolates of E. coli and 16 (44%) isolates of Shigella spp. In conclusion, E. coli proved to be the main cause of diarrhoea in young children in this study, followed by rotavirus A and protozoa. Determination of diarrhoea aetiology and antibiotic susceptibility patterns of diarrhoeal pathogens and improved hygiene are important for clinical management and controlled strategic planning to reduce the burden of infection.

    Using the Small Animal Veterinary Surveillance Network (SAVSNET), a national small animal disease-surveillance scheme, information on gastrointestinal disease was collected for a total of 76 days between 10 May 2010 and 8 August 2011 from 16,223 consultations (including data from 9115 individual dogs and 3462 individual cats) from 42 premises belonging to 19 UK veterinary practices. During that period, 7% of dogs and 3% of cats presented with diarrhoea. Adult dogs had a higher proportional morbidity of diarrhoea (PMD) than adult cats (P <0.001). This difference was not observed in animals <1 year old. Younger animals in both species had higher PMDs than adult animals (P < 0.001). Neutering was associated with reduced PMD in young male dogs. In adult dogs, miniature Schnauzers had the highest PMD. Most animals with diarrhoea (51%) presented having been ill for 2-4 days, but a history of vomiting or haemorrhagic diarrhoea was associated with a shorter time to presentation. The most common treatments employed were dietary modification (66% of dogs; 63% of cats) and antibacterials (63% of dogs; 49% of cats). There was variability in PMD between different practices. The SAVNET methodology facilitates rapid collection of cross-sectional data regarding diarrhoea, a recognised sentinel for infectious disease, and characterises data that could benchmark clinical practice and support the development of evidence-based medicine.

    This study examined the effects of meteorological factors, particularly, extreme weather events, on the prevalence of childhood diarrhoeal disease in Matlab, Bangladesh. Logistic regression models were used to examine impacts of temperature, rainfall and the extreme weather factors (the number of hot days and days with heavy rainfall) on childhood diarrhoea from 2000 to 2006 at the bari (cluster of dwellings) level. The results showed that the increases in the number of hot days and days with heavy rainfall were associated with an increase in daily diarrhoea cases by 0·8-3·8% and 1-6·2%, respectively. The results from multivariable stepwise models showed that the extreme weather factors were still positively associated with childhood diarrhoea, while the associations for average temperature and rainfall could be negative after other variables were controlled. The findings showed that not only the intensity, but also the frequency of extreme weather events had significant effects on childhood diarrhoea.

    The aim of this study was to determine whether Saccharomyces boulardii prevents and treats diarrhoea and antibiotic-associated diarrhoea (AAD) in children. A total of 333 hospitalised children with acute lower respiratory tract infection were enrolled in a 2-phase open randomised controlled trial. During the 1st phase, all children received intravenous antibiotics (AB). They were randomly allocated to group A (S. boulardii 500 mg/day + AB, n=167) or group B (AB alone, n=166) and followed for 2 weeks. Diarrhoea was defined as ≥3 loose/watery stools/day during at least 2 days, occurring during treatment and/or up to 2 weeks after AB therapy had stopped. AAD was considered when diarrhoea was caused by Clostridium difficile or when stool cultures remained negative. In the 2nd phase of the study, group B patients who developed diarrhoea were randomly allocated to two sub-groups: group B1 (S. boulardii + oral rehydration solution (ORS)) and group B2 (ORS alone). Data from 283 patients were available for analysis. Diarrhoea prevalence was lower in group A than in group B (11/139 (7.9%) vs. 42/144 (29.2%); relative risk (RR): 0.27, 95% confidence interval (CI): 0.1-0.5). S. boulardii reduced the risk of AAD (6/139 (4.3%) vs. 28/144 (19.4%); RR: 0.22; 95% CI: 0.1-0.5). When group B patients developed diarrhoea (n=42), S. boulardii treatment during 5 days (group B1) resulted in lower stool frequency (P<0.05) and higher recovery rate (91.3% in group B1 vs. 21.1% in B2; P<0.001). The mean duration of diarrhoea in group B1 was shorter (2.31±0.95 vs. 8.97±1.07 days; P<0.001). No adverse effects related to S. boulardii were observed. S. boulardii appeared to be effective in the prevention and treatment of diarrhoea and AAD in children treated with intravenous antibiotics.

    Major hindrances to controlling the current childhood obesity epidemic include access to prevention and/or treatment programs that are affordable, provide minimal barriers for participation, and are available to the general public. Moreover, successful childhood obesity prevention efforts will require coordinated partnerships in multiple sectors such as government, health care, school/afterschool, and the community but very few documented sustainable programs currently exist. Effective, community-based health and wellness programs with a focus on maintaining healthy weight via physical activity and healthy eating have the potential to be a powerful referral resource for pediatricians and other healthcare professionals who have young patients who are overweight/obese. The Miami Dade County Department of Parks, Recreation and Open Spaces in partnership with the University of Miami UHealth Systems have created a “Park Prescription Program (Parks Rx 4HealthTM)” that formally coordinates pediatricians, families, parents, caregivers, and child/adolescents to provide daily obesity-prevention activities. This Parks Rx 4HealthTM program that we describe here allows UHealth pediatricians to seamlessly refer their overweight and obese patients to Fit2PlayTM, an evidence-based, park-based afterschool health and wellness program. Measurable outcomes that include body mass index, blood pressure, fitness, and nutrition knowledge are being collected at baseline and at 3-and 6-mo after referral to document patient progress. Results are then shared with the referring physician so they can follow up with the patient if necessary. Identifying successful models that integrate primary care, public health, and community-based efforts is important to accelerating progress in preventing childhood obesity. Effective, community-based health and wellness programs with a focus on physical activity and nutrition education could be a powerful referral resource for pediatricians who have

    The association of infantile diarrhoea with the presence of garbage in the environment was investigated in Canabrava, a peripheral neighbourhood of Salvador, northeast of Brazil. A cross-sectional study was conducted with all the 184 children aged less than two years residing in Canabrava, which is located close to the city garbage dump. Variables selected for study included the method used for the disposal of excrement, type of floor, mother's education, unemployment of the head of the family, regularity of the water supply, presence of toilet, storage of garbage inside the house, age, gender, duration of breastfeeding, and the number of people per room. The estimated prevalence of diarrhoea was 21.2%. Exposure to garbage in the environment was found to be the most important factor associated with diarrhoea (adjusted odds ratio [AOR] = 3.98, 95% CI 1.56-10.13). Other important variables were the mother's education (AOR = 2.79, 95% CI 1.09-7.13), maternal breastfeeding (AOR = 2.30, 95% CI 1.05-5.04), and unemployment of the head of the family (AOR = 2.09, 95% CI 0.93-4.69). These findings indicate the necessity of adopting solutions in the public domain and of intersectorial policies for the reduction of diarrhoea.

    1. We set out to ascertain the role of tachykinins, neurokinin A and substance P, in castor oil-induced diarrhoea in rats as disclosed by the inhibitory effect of the non-peptide NK1- and NK2-receptor antagonists. SR 140333 and SR 48968, respectively. 2. SR 48968 (0.02 to 20 micrograms kg-1, s.c. or p.o.), and the opioid receptor agonist loperamide (1-10 mg kg-1, p.o.), dose-dependently prevented castor oil effects: % inhibition vs castor oil, diarrhoea 0 to 100, increase in faecal mass 7 to 90 and water content 16 to 90. SR 140333 (0.02 to 20 micrograms kg-1, s.c.) and the platelet activating factor antagonist SR 27417 (5 to 500 micrograms kg-1, p.o.) did not prevent the increase in faecal water content, but reduced faecal mass (35 to 66%) and diarrhoea (0 to 57%). 3. The R-enantiomers of tachykinin NK1 and NK2 receptor antagonists, SR 140603 and SR 48605 (both at 2 or 20 micrograms kg-1, s.c.) had no effect other than reducing faecal mass at the highest dose tested. 4. SR 48968 (20 micrograms kg-1, p.o.) but not loperamide (10 mg kg-1, p.o.) given 24 h before castor oil, still slightly but significantly reduced by 30% the increase of faecal mass output; both treatments significantly reduced (30 to 70%) the effect of castor oil on faecal water content, although the incidence of diarrhoea was only slightly less than in controls. 5. In castor oil-treated rats, naloxone (2 mg kg-1, s.c.) completely blocked the antidiarrhoeal action of loperamide (10 mg kg-1, p.o.) but not of SR 48968 (20 micrograms kg-1, p.o.): a similar result was obtained on faecal mass and water content. 6. Castor oil strongly increased the occurrence of manometrically recorded propulsive giant contractions (500 to 1000% over control values) of transverse and distal colon, this effect being significantly prevented (80 to 100%) by SR 48968 and loperamide and partially by SR 140333 (35% distal colon, 70% transverse colon). 7. In castor oil free rats, loperamide but not SR 48968 or SR 140333

    Introduction Diarrhoea diseases remain a major public health threat with nearly 1.7 billion cases annually worldwide occurring in all age groups. In Ghana diarrhoea kills about 14,000 children under five years annually. We therefore analysed data to determine the morbidity pattern of diarrhoea diseases in the Central Region of Ghana. Methods Health facility morbidity data was reviewed from 2008-2012. Monthly data on diarrhoeal diseases were extracted from District Health Information Management System database by sex, age group and districts. Data for bloody diarrhoea were extracted from monthly surveillance report forms. Data was analysed descriptively and expressed as frequencies and proportionate morbidity rates (pmr). Aberrations were determined using C2 threshold. Results The total cases of all morbidity from 2008 to 2012 were 7,642,431. Diarrhoea diseases formed 4% (306854/7642431) of total morbidity. Children under one year (pmr= 8.4%) and males (pmr= 4.4%) were the most affected. Bloody diarrhea formed 2.2% (6835/306854) of diarrhoea cases with 0.7 %(45/6835) laboratory confirmed. Diarrhoea cases peaked from January to March throughout the study period with highest frequency 9.3% (28511/306854) in June. The mean monthly distribution of diarrhoea cases was 25571.17±1389.91. Poorest districts had significantly lower odds of getting bloody diarrhoea than non-poorest districts OR = 0.73 (95%CI = 0.70-0.77). Conclusion Diarrhoea characterized 4% of total morbidity presenting at health facilities in the region from 2008 to 2012. The diarrhoea morbidity rate decreased with increased age. Diarrhoea was higher among non poorest districts. The rate was highest in the month of June over the five year period. Bloody diarrhoea cases were mostly untested. We recommended that stool samples should be taken for laboratory testing for bloody diarrhoea cases. PMID:28149442

    Community capacity for organization and collaboration has been shown to be a powerful tool for improving the health and well-being of communities. Since 1994 the Washington State Family Policy Council has supported the development of community capacity in 42 community public health and safety networks. Community networks bring local communities together to restructure natural supports and local resources to meet the needs of families and children, and increase cross-system coordination and flexible funding streams to improve local services and policy. In this study, researchers sought to demonstrate the strong impact of the community networks’ capacity to interrupt health and social problems. Findings suggest that community networks reduce health and safety problems for the entire community population. Further, community networks with high community capacity reduced adverse childhood experiences (ACE) in young adults ages 18–34. PMID:22970785

    Selected probiotics (mainly Lactobacilli, and particularly LGG, and Saccharomyces boulardii) have recently demonstrated a therapeutic efficacy in acute diarrhoea, if used in the early phase of infection and at high concentration. Further data are needed to clarify their effect for prevention and travellers' diarrhoea. The mechanisms of action of probiotics need to be fully elucidated but seem to include a complex interaction of epithelial, molecular, metabolic and immune responses. There is an increasing evidence that different micro-organisms show different properties and efficacy. An accurate identification and selection of the strains, the dose and the patients are thus crucial for a correct therapeutic approach. Prebiotics can modify the intestinal flora and interact with the immune system of the host against specific pathogens. However, clinical trials are currently limited and a beneficial effect of prebiotics in acute diarrhoea is still lacking. In developing countries zinc supplementation demonstrated a significant reduction of fecal excretion, duration, severity and persistency of diarrhoea. Moreover, zinc may improve immune status, intestinal permeability, epithelial and enzymatic functions, and transport of electrolytes. The use of zinc in addition to oral rehydration solution (ORS) could thus theoretically improve the treatment and reduce the complications of diarrhoea worldwide. However, in developed countries, no trial using zinc supplementation in patients with acute diarrhoea has been published yet and the cost-benefit ratio of zinc supplementation needs to be assessed.

    This placebo-controlled double-blind study was conducted to evaluate effects of Enterococcus faecium DSM 10663 NCIMB 10415 (EcF) orally given from birth to weaning on diarrhoea and performance of piglets. At the first 3 days postnatum (p.n.), piglets from 54 [verum group (VG)] and 60 [placebo group (PG)] sows got 1 g of a gel directly per mouth by a dosing device. Gel for the VG contained 2.8 x 10(9) colony forming units (CFU) EcF/g. From day 4 p.n. until weaning (24 +/- 3.2 days p.n.) a liquid additive was given that administered twice a day 1.26 x 10(9) CFU EcF to each VG piglet. In case of diarrhoea, an electrolyte solution was used which provided daily 2.9 and 5.8 (week 1 and >or= 2, respectively) x 10(8) CFU EcF per VG piglet. Diarrhoea scores were defined as follows: (i) no diarrhoea; (ii) piglets developed diarrhoea, but were vital and (iii) piglets suffered from diarrhoea and additionally looked pale, developed rough coat, showed slackening of the flank and lethargy. Counts of viable born, stillborn and weaned piglets were normal and not different between groups (p > 0.05). Placebo group vs. VG piglets suffered more frequently from diarrhoea (40.0 vs. 14.8%, p < 0.05). Duration of diarrhoea was not affected by feeding EcF (2.2 +/- 0.81 days, p > 0.05). Diarrhoea score was lower in VG vs. PG (1.2 vs. 1.5 +/- 0.54, p < 0.05) and the daily weight gain (DWG) was higher by 17 g/day (p < 0.05). Results suggest that the daily oral supplementation of EcF from birth to weaning reduces the portion of piglets suffering from diarrhoea. This may improve performance, as the higher DWG indicates. In contrast, no obvious benefit seems to result from an additional supply of EcF via electrolyte solution when diarrhoea is always present.

    As rates of childhood obesity and overweight rise around the world, researchers and policy makers seek new ways to reverse these trends. Given the concentration of the world's population, income inequalities, unhealthy diets, and patterns of physical activity in cities, urban areas bear a disproportionate burden of obesity. To address these issues, in 2008, researchers from the City University of New York and London Metropolitan University created the Municipal Responses to Childhood Obesity Collaborative. The Collaborative examined three questions: What role has city government played in responding to childhood obesity in each jurisdiction? How have municipal governance structures in each city influenced its capacity to respond effectively? How can policy and programmatic interventions to reduce childhood obesity also reduce the growing socioeconomic and racial/ethnic inequities in its prevalence? Based on a review of existing initiatives in London and New York City, the Collaborative recommended 11 broad strategies by which each city could reduce childhood obesity. These recommendations were selected because they can be enacted at the municipal level; will reduce socioeconomic and racial/ethnic inequalities in obesity; are either well supported by research or are already being implemented in one city, demonstrating their feasibility; build on existing city assets; and are both green and healthy.

    Chronic diarrhoea is a common presenting symptom in both primary care medicine and in specialized gastroenterology clinics. It is estimated that >5% of the population has chronic diarrhoea and nearly 40% of these patients are older than 60 years. Clinicians often need to select the best diagnostic approach to these patients and choose between the multiple diagnostic tests available. In 2014 the Catalan Society of Gastroenterology formed a working group with the main objective of creating diagnostic algorithms based on clinical practice and to evaluate diagnostic tests and the scientific evidence available for their use. The GRADE system was used to classify scientific evidence and strength of recommendations. The consensus document contains 28 recommendations and 6 diagnostic algorithms. The document also describes criteria for referral from primary to specialized care.

    Adverse childhood experiences (ACE) can possibly permanently alter the stress response system, affect the glutamatergic system and influence hippocampal volume in mood disorders. The aim of the study is to investigate the association between glutamate levels in the hippocampus, measured through single proton magnetic resonance spectroscopy (1H-MRS), and ACE in patients affected by mood disorders and healthy controls. Higher levels of early stress associate to reduced levels of Glx/Cr in the hippocampus in depressed patients but not in healthy controls. Exposure to stress during early life could lead to a hypofunctionality of the glutamatergic system in the hippocampus of depressed patients. Abnormalities of glutamatergic signaling could then possibly underpin the structural and functional abnormalities observed in patients affected by mood disorders.

    Exposure to interparental violence is associated with negative outcomes, such as depression, post-traumatic stress disorder and reduced cognitive abilities. However, little is known about the potential effects of witnessing domestic violence during childhood on gray matter volume (GMV) or cortical thickness. High-resolution 3.0 T volumetric scans (Siemens Trio Scanner) were obtained on 52 subjects (18-25 years) including 22 (6 males/16 females) with a history of visually witnessing episodes of domestic violence, and 30 (8 males/22 females) unexposed control subjects, with neither a current nor past DSM-IV Axis I or II disorder. Potential confounding effects of age, gender, level of parental verbal aggression, parental education, financial stress, full scale IQ, and total GMV, or average thickness were modeled using voxel based morphometry and FreeSurfer. Witnessing domestic violence subjects had a 6.1% GMV reduction in the right lingual gyrus (BA18) (P = 0.029, False Discovery Rate corrected peak level). Thickness in this region was also reduced, as was thickness in V2 bilaterally and left occipital pole. Theses regions were maximally sensitive to exposure to witnessing domestic violence between 11-13 years of age. Regional reductions in GMV and thickness were observed in both susceptible and resilient witnessing domestic violence subjects. Results in subjects witnessing domestic violence were similar to previously reported results in subjects with childhood sexual abuse, as the primary region affected was visual cortex. Brain regions that process and convey the adverse sensory input of the abuse may be specifically modified by this experience, particularly in subjects exposed to a single type of maltreatment. Exposure to multiple types of maltreatment is more commonly associated with morphological alterations in corticolimbic regions. These findings fit with preclinical studies showing that visual cortex is a highly plastic structure.

    To determine the prevalence of giardiasis in Gambian children with chronic diarrhoea and to assess their response to treatment, 31 children with chronic diarrhoea and malnutrition were investigated for giardiasis using a combination of serology (specific antigiardia IgM antibody) and microscopy of faeces and jejunal biopsy specimens. Fourteen of 31 children with chronic diarrhoea had giardiasis compared with only four of 33 healthy age and sex matched control children. Four of 15 malnourished children without diarrhoea were giardia positive. Twenty-three children with chronic diarrhoea were reinvestigated after treatment with metronidazole; giardia was found in 11 of them. These results show that giardia is highly prevalent in children with chronic diarrhoea and malnutrition and that the infection does not respond to standard therapeutic measures. PMID:2025005

    Background Diarrhoeal illness is a major public health problem for children worldwide, particularly among developing countries, and is a proxy condition for severe dehydration. It has been hypothesized that severe dehydration in the first 6 months of life could be associated with increased blood pressure later in life. This study aimed to explore whether frequency of diarrhoea is associated with elevated blood pressure in children in a setting with a high incidence of diarrhoeal disease. Methods The present study is a cross-sectional study of blood pressure among children from a longitudinal child diarrhoeal disease cohort in Lima, Peru. From 2001 to 2006, daily diarrhoeal surveillance was made. Children were revisited in 2006 and blood pressure was measured. Diarrhoeal exposures were evaluated in terms of total number of diarrhoea days, number of episodes of diarrhoea, persistent diarrhoeal episodes and by the quartiles of daily incidence and episode incidence of diarrhoea. Results The overall incidence of diarrhoeal episodes at age under 1 year was 4.35 (95% confidence interval: 3.79-4.98) and under 5 years was 2.80 (95% confidence interval: 2.69-2.92). No association was observed between the total number of diarrhoeal days, diarrhoeal episodes or diarrhoeal incidence rates with childhood blood pressure. There was weak evidence that hospital admission due to severe dehydration in the first year of life showed a gradient towards an increase in both, systolic and diastolic blood pressure. Conclusion In the first study to date to examine the association in a setting with a high incidence of diarrhoeal disease, diarrhoeal frequency did not show an association with increased blood pressure. Our observations of elevated levels of blood pressure among those admitted into hospitals in the first year of life are in line with the original hypothesis of dehydration in early infancy and high blood pressure. However, the effect of episodes of severe dehydration on later blood

    This paper examined care-seeking behaviour and its associated risk factors when a family member had diarrhoea. Data was obtained from a survey conducted in Chikwawa, a district in Southern Malawi. Chikwawa is faced with a number of environmental and socioeconomic problems and currently diarrhoea morbidity in the district is estimated at 24.4%, statistically higher than the national average of 17%. Using hierarchically built data from a survey of 1403 households nested within 33 communities, a series of two level binary logistic regression models with Bayesian estimation were used to determine predictors of care-seeking behaviour. The results show that 68% of mothers used oral rehydration solutions (ORS) the last time a child in their family had diarrhoea. However, when asked on the action they take when a member of their household has diarrhoea two thirds of the mothers said they visit a health facility. Most respondents (73%) mentioned distance and transport costs as the main obstacles to accessing their nearest health facility and the same proportion of respondents mentioned prolonged waiting time and absence of health workers as the main obstacles encountered at the health facilities. The main predictor variables when a member of the family had diarrhoea were maternal age, distance to the nearest health facility, school level, and relative wealth, household diarrhoea endemicity, and household size while the main predictor variables when a child had diarrhoea were existence of a village health committee (VHC), distance to the nearest health facility, and maternal age. Most households use ORS for the treatment of diarrhoea and village health committees and health surveillance assistants (HSAs) are important factors in this choice of treatment. Health education messages on the use and efficacy of ORS to ensure proper and prescribed handling are important. There is need for a comprehensive concept addressing several dimensions of management and proper coordination

    Socio-behavioural factors and pathogens associated with childhood diarrhoea are of global public health concern. Our survey in 696 children aged ⩽2 years in rural West Bengal detected rotavirus as sole pathogen in 8% (17/199) of diarrhoeic stool specimens. Other organisms were detected along with rotavirus in 11% of faecal specimens. A third of the children with rotavirus diarrhoea, according to Vesikari score, had severe illness. The top four rotavirus genotypes were G9P[4] (28%), G1P[8] (19%), G2P[4] (14%) and G8P[4] (8%). In the multivariate model, the practice of 'drawing drinking water by dipping a pot in the storage vessel' [adjusted odds ratio (aOR) 2·21, 95% confidence interval (CI) 1·03-4·74, P = 0·041], and 'children aged ⩽6 months with non-exclusive breastfeeding' (aOR 2·07, 95% CI 1·1-3·82, P = 0·024) had twice the odds of having diarrhoea. Incidence of rotavirus diarrhoea was 24/100 child-years in children aged >6-18 months, 19/100 child-years in children aged >18-24 months and 5/100 child-years in those aged ⩽6 months. Results have translational implications for future interventions including vaccine development.

    More than one-fifth of the world's population live in extreme poverty, where a lack of safe water and adequate sanitation enables high rates of enteric infections and diarrhoea to continue unabated. Although oral rehydration therapy has greatly reduced diarrhoea-associated mortality, enteric infections still persist, disrupting intestinal absorptive and barrier functions and resulting in up to 43% of stunted growth, affecting one-fifth of children worldwide and one-third of children in developing countries. Diarrhoea in children from impoverished areas during their first 2 years might cause, on average, an 8 cm growth shortfall and 10 IQ point decrement by the time they are 7-9 years old. A child's height at their second birthday is therefore the best predictor of cognitive development or 'human capital'. To this 'double burden' of diarrhoea and malnutrition, data now suggest that children with stunted growth and repeated gut infections are also at increased risk of developing obesity and its associated comorbidities, resulting in a 'triple burden' of the impoverished gut. Here, we Review the growing evidence for this triple burden and potential mechanisms and interventions that must be understood and applied to prevent the loss of human potential and unaffordable societal costs caused by these vicious cycles of poverty.

    Quercitrin (3-rhamnosylquercetin) is a bioflavonoid contained in several crude drugs traditionally used for its antidiarrhoeal activity. The antidiarrhoeic effect of quercitrin on experimental chronic diarrhoea in rats was studied. Adult rats were fed for 14 days with a synthetic diet in which all soluble carbohydrates were substituted by lactose, resulting in chronic diarrhoea with body weight loss, colonic hyperplasia, reduced average cell size, increased alkaline phosphatase activity, increased mucus production and cytopathological alterations of the enterocyte. The rest of the animals were allowed to recover from chronic diarrhoea for 3 or 7 days, by feeding them with a standard diet, and half of them were also given quercitrin orally (50 mg/kg day). Diarrhoea ceased 48 h after lactose withdrawal, and body weight recovery was apparent after 3 days. Nevertheless, most of the alterations of the colonic mucosa persisted at that time. Quercitrin-treated rats had less diarrhoeal output and did not show mucosal hyperplasia after three days of treatment. All animals had greatly recovered by the seventh day, but histological alterations were still present, although to a lesser extent in quercitrin-treated rats. Quercitrin and related flavonoids may play a role in intestinal repair following chronic mucosal injury.

    5-Fluorouracil (5-FU)-based chemotherapy is frequently associated with diarrhoea. We compared two 5-FU-based regimens and the effect of Lactobacillus and fibre supplementation on treatment tolerability. Patients diagnosed with colorectal cancer (n=150) were randomly allocated to receive monthly 5-FU and leucovorin bolus injections (the Mayo regimen) or a bimonthly 5-FU bolus plus continuous infusion (the simplified de Gramont regimen) for 24 weeks as postoperative adjuvant therapy. On the basis of random allocation, the study participants did or did not receive Lactobacillus rhamnosus GG supplementation (1–2 × 1010 per day) and fibre (11 g guar gum per day) during chemotherapy. Patients who received Lactobacillus had less grade 3 or 4 diarrhoea (22 vs 37%, P=0.027), reported less abdominal discomfort, needed less hospital care and had fewer chemotherapy dose reductions due to bowel toxicity. No Lactobacillus-related toxicity was detected. Guar gum supplementation had no influence on chemotherapy tolerability. The simplified de Gramont regimen was associated with fewer grade 3 or 4 adverse effects than the Mayo regimen (45 vs 89%), and with less diarrhoea. We conclude that Lactobacillus GG supplementation is well tolerated and may reduce the frequency of severe diarrhoea and abdominal discomfort related to 5-FU-based chemotherapy. PMID:17895895

    In an attempt to prevent diarrhoea in a rural community in central Bolivia, an international non-governmental organization implemented a pilot project to improve drinking water quality using gravity-fed, household-based, ceramic water filters. We assessed the performance of the filters by conducting a five-month randomized controlled trial among all 60 households in the pilot community. Water filters eliminated thermotolerant (faecal) coliforms from almost all intervention households and significantly reduced turbidity, thereby improving water aesthetics. Most importantly, the filters were associated with a 45.3% reduction in prevalence of diarrhoea among the study population (p = 0.02). After adjustment for household clustering and repeated episodes in individuals and controlling for age and baseline diarrhoea, prevalence of diarrhoea among the intervention group was 51% lower than controls, though the protective effect was only borderline significant (OR 0.49, 95% CI: 0.24, 1.01; p = 0.05). A follow-up survey conducted approximately 9 months after deployment of the filters found 67% being used regularly, 13% being used intermittently, and 21% not in use. Water samples from all regularly used filters were free of thermotolerant coliforms.

    Research suggests that adverse events in childhood, such as childhood physical, sexual, and emotional abuse, confer risk for later sexual assault. Psychological distress, coping strategies, and sexual behavior may help explain the path from childhood abuse to revictimization. The present study explored how the use of sex to regulate negative affect (SRNA) operates independently, and in combination with other psychosocial factors to increase college women's (N=541) risk of experiencing prospective adult sexual assault (ASA). Sequential multiple mediator models in Mplus were used to assess the effect of three different forms of childhood abuse on prospective ASA, both independently and while controlling for other forms of childhood abuse. The indirect effect of adolescent sexual assault (AdolSA), depressive symptoms, SRNA, and participants' response to a sex-related vignette was tested using bias-corrected bootstrapping. In the full path model, childhood emotional abuse and AdolSA predicted ASA, while childhood physical and sexual abuse were directly associated with AdolSA, but not ASA. Additionally, depressive symptoms and participants' estimate of their likely behavior in a sex-related vignette directly predicted prospective ASA. Results using bootstrapping revealed that a history of childhood abuse predicted prospective ASA via diverse direct and indirect paths, as well as through a similar multiple mediator path. Overall, findings suggest that a combination of affective, coping, and sexual expectancy factors contribute to risk for revictimization in adult survivors of childhood abuse. Future research directions and targets for risk-reduction programming are discussed.

    Tropheryma whipplei was detected in preliminary studies in faeces of young children with diarrhoea and also in faeces of asymptomatic persons, not only in Europe but also in Africa. In this study, the link between this bacterium and the presence of acute diarrhoea was evaluated in a large group of children. From December 2009 to January 2013, rectal swabs collected from 3796 children in the emergency departments of university hospitals in Marseille, France, were analysed: 555 children (245 female and 310 male, from 6 days to 6 years old) with acute diarrhoea defined as at least three loose stools per day for <1 week and 3241 children (1444 female and 1797 male, from 22 days to 6 years old) without diarrhoea. Specific quantitative real-time PCR was performed to detect the presence of T. whipplei and of two enteric pathogens Clostridium difficile and Giardia duodenalis. Tropheryma whipplei was significantly more common in children with diarrhoea (22/555, 4%) than without (56/3241, 1.7%; p 0.001). Neither C. difficile nor G. duodenalis showed this association. For C. difficile, 39 of 531 (7.3%) children with diarrhoea were positive versus 184 of 3119 (5.9%) of children without diarrhoea (p 0.25). For G. duodenalis, 2 of 529 (0.37%) children with diarrhoea were positive versus 5 of 3119 (0.16%) children without diarrhoea (p 0.26). Tropheryma whipplei was found more commonly in autumn. Tropheryma whipplei is significantly associated with diarrhoea in children, suggesting that the bacterium may be a cause of acute diarrhoea.

  4. Zinc sulphate for treatment and prevention of diarrhoea and other conditions in children in Papua New Guinea.

    PubMed

    Duke, Trevor

    2011-01-01

    Over the last 10 years more than 40 randomized trials of zinc sulphate in diarrhoea have been done in developing countries throughout the world. Almost all have shown a benefit of zinc therapy for 5-10 days, if given with oral rehydration solution, in reducing the severity and duration of severe diarrhoea and preventing diarrhoea in the subsequent 3 months. Zinc has also been proven to reduce mortality in the management of children with severe malnutrition. Two studies have shown a benefit of zinc treatment on the clinical resolution of pneumonia and another study from Africa showed that zinc adjuvant treatment led to a significant reduction in mortality from pneumonia. Despite this overwhelming evidence, few countries in the Asia-Pacific region have scaled up the use of zinc in the treatment or prevention of diarrhoea or other infections. The reasons for this are several, including obstacles to incorporating new treatments into routine drug procurement and distribution mechanisms, and failure to appreciate the steps involved in the promotion of new routine treatments. A much higher priority must be given to ensuring that children with malnutrition, diarrhoea and other infections have access to zinc and oral rehydration solution--both of which are low-cost and life-saving treatments.

  5. Oral therapy of infant diarrhoea.

    Immediate oral therapy at home by the mother using a sugar-salt solution offers a real prospect of reducing mortality from gastroenteritis among preschool children in the developing world. The sugar-salt solution enables the mother to take action against a disease which is the most frequent cause of death among young children. In Lagos, Nigeria, knowledge of the treatment has diffused rapidly in a low-income community served by a clinic run by the Institute of Child Health. In a recent study, women expecting their 1st child and others who had never used the service were able to describe the sugar-salt solution treatment taught to all who attend the clinic. However, of the 217 women who described the method, less than 1/2 (34%) could give the correct proportions of sugar and salt to be used (4 teaspoons and 1/4 teaspoon respectively in a standard local beer bottle filled with water). Most errors involved the use of too much salt. In nearly 1/2 these cases, 4 times too much salt was described, and in 3 cases, 16 times too much salt. Under these circumstances, we can expect a possible increase in children admitted with hypernatremia, a situation which would bring the method into disrepute. Any attempt to transfer health skills to mothers in developing countries must recognize, as in this example, the problems posed by lack of education and unfamiliarity with measurement terms such as "1/4" or even "a teaspoon." What is required is a simple measuring spoon giving the actual quantity to be used. Manufactured on a large scale in plastic, this would be inexpensive. Ideally, every mother of a preschool child should have 1, but where this is not possible, all health workers should have such spoons so that they can measure into a mother's hand the correct amounts. In this way the mother can make correct use of a treatment which has such potential for saving lives.

  6. Bromelain protects piglets from diarrhoea caused by oral challenge with K88 positive enterotoxigenic Escherichia coli

    PubMed Central

    Chandler, D; Mynott, T

    1998-01-01

    Background—K88 positive enterotoxigenic Escherichia coli (K88+ ETEC) is an important cause of diarrhoea in young piglets. K88+ ETEC pathogenesis relies on attachment to specific glycoprotein receptors located on the intestinal mucosa. Proteolytic treatment of these receptors in vitro and in vivo prevents attachment of K88+ ETEC to piglet small intestines and may be of clinical use to prevent K88+ ETEC pathogenesis. 
Aims—To determine whether bromelain, a proteolytic extract obtained from pineapple stems, would protect piglets against K88+ ETEC diarrhoea and to confirm and extend earlier findings on the effects of bromelain on K88+ ETEC receptors in vivo. 
Methods—Bromelain (0, 12.5, or 125 mg) was orally administered to just weaned piglets for 10 days. One day following commencement of bromelain treatment, piglets were challenged with K88+ ETEC (5 × 1010 K88ac:0149) for seven days. Intestinal contents from unchallenged piglets were obtained via an intestinal fistula, and tested for their ability to bind K88+ ETEC before and after bromelain treatment. 
Results—Both doses of bromelain were successful in reducing the incidence of K88+ ETEC diarrhoea and protected piglets from life threatening disease. Bromelain treated pigs also had significantly increased weight gain compared with untreated pigs. Bromelain only temporarily inhibited K88+ ETEC receptor activity, with receptor activity being regenerated 30 hours following treatment, consistent with the regeneration of new enterocytes. 
Conclusion—Results show that bromelain can temporarily inactivate ETEC receptors in vivo and protect against ETEC induced diarrhoea. Bromelain may therefore be an effective prophylaxis against ETEC infection.

    Abstract Objective To investigate the clinical characteristics of children who died from diarrhoea in low- and middle-income countries, such as the duration of diarrhoea, comorbid conditions, care-seeking behaviour and oral rehydration therapy use. Methods The study included verbal autopsy data on children who died from diarrhoea between 2000 and 2012 at seven sites in Bangladesh, Ethiopia, Ghana, India, Pakistan, Uganda and the United Republic of Tanzania, respectively. Data came from demographic surveillance sites, randomized trials and an extended Demographic and Health Survey. The type of diarrhoea was classified as acute watery, acute bloody or persistent and risk factors were identified. Deaths in children aged 1 to 11 months and 1 to 4 years were analysed separately. Findings The proportion of childhood deaths due to diarrhoea varied considerably across the seven sites from less than 3% to 30%. Among children aged 1–4 years, acute watery diarrhoea accounted for 31–69% of diarrhoeal deaths, acute bloody diarrhoea for 12–28%, and persistent diarrhoea for 12–56%. Among infants aged 1–11 months, persistent diarrhoea accounted for over 30% of diarrhoeal deaths in Ethiopia, India, Pakistan, Uganda and the United Republic of Tanzania. At most sites, more than 40% of children who died from persistent diarrhoea were malnourished. Conclusion Persistent diarrhoea remains an important cause of diarrhoeal death in young children in low- and middle-income countries. Research is needed on the public health burden of persistent diarrhoea and current treatment practices to understand why children are still dying from the condition. PMID:25378757

    Purpose: To estimate the rate of disease control after conformal radiation therapy using reduced clinical target volume (CTV) margins and to determine factors that predict for tumor progression. Methods and Materials: Eighty-eight children (median age, 8.5 years; range, 3.2-17.6 years) received conformal or intensity modulated radiation therapy between 1998 and 2009. The study group included those prospectively treated from 1998 to 2003, using a 10-mm CTV, defined as the margin surrounding the solid and cystic tumor targeted to receive the prescription dose of 54 Gy. The CTV margin was subsequently reduced after 2003, yielding 2 groups of patients: those treated with a CTV margin greater than 5 mm (n=26) and those treated with a CTV margin less than or equal to 5 mm (n=62). Disease progression was estimated on the basis of additional variables including sex, race, extent of resection, tumor interventions, target volume margins, and frequency of weekly surveillance magnetic resonance (MR) imaging during radiation therapy. Median follow-up was 5 years. Results: There was no difference between progression-free survival rates based on CTV margins (>5 mm vs ≤5 mm) at 5 years (88.1% ± 6.3% vs 96.2% ± 4.4% [P=.6386]). There were no differences based on planning target volume (PTV) margins (or combined CTV plus PTV margins). The PTV was systematically reduced from 5 to 3 mm during the time period of the study. Factors predictive of superior progression-free survival included Caucasian race (P=.0175), no requirement for cerebrospinal fluid shunting (P=.0066), and number of surveillance imaging studies during treatment (P=.0216). Patients whose treatment protocol included a higher number of weekly surveillance MR imaging evaluations had a lower rate of tumor progression. Conclusions: These results suggest that targeted volume reductions for radiation therapy using smaller margins are feasible and safe but require careful monitoring. We are currently investigating

    Background Diarrhoea is the second leading cause of child mortality worldwide. Low- and middle-income countries are particularly burdened with this both preventable and treatable condition. Targeted interventions include the provision of safe water, the use of sanitation facilities and hygiene education, but are implemented with varying local success. Objective To determine the prevalence of and factors associated with diarrhoea in children under five years of age in rural Burundi. Design A cross-sectional survey was conducted among 551 rural households in northwestern Burundi. Areas of inquiry included 1) socio-demographic information, 2) diarrhoea period prevalence and treatment, 3) behaviour and knowledge, 4) socio-economic indicators, 5) access to water and water chain as well as 6) sanitation and personal/children's hygiene. Results A total of 903 children were enrolled. The overall diarrhoea prevalence was 32.6%. Forty-six per cent (n=255) of households collected drinking water from improved water sources and only 3% (n=17) had access to improved sanitation. We found a lower prevalence of diarrhoea in children whose primary caretakers received hygiene education (17.9%), boiled water prior to its utilisation (19.4%) and were aged 40 or older (17.9%). Diarrhoea was associated with factors such as the mother's age being less than 25 and the conviction that diarrhoea could not be prevented. No gender differences were detected regarding diarrhoea prevalence or the caretaker's decision to treat. Conclusions Diarrhoea prevalence can be reduced through hygiene education and point-of use household water treatment such as boiling. In order to maximise the impact on children's health in the given rural setting, future interventions must assure systematic and regular hygiene education at the household and community level.

    The association between Cryptosporidium, chronic diarrhoea and a proximal small intestinal mucosal enteropathy was reviewed over a six and a half year period. One hundred and twenty three children with cryptosporidiosis and no clinical evidence of immune deficiency were identified. 50% of children excreting only Cryptosporidium had chronic diarrhoea. Most cases (63%) of chronic diarrhoea occurred in the first two years of life. A mild to moderate enteropathy was present in all nine children undergoing a small intestinal biopsy and seven showed the presence of Cryptosporidium adhering to villous epithelium. All patients eventually recovered spontaneously. Cryptosporidium is a cause of chronic diarrhoea and a proximal small intestinal mucosal enteropathy in children without immune deficiency. Screening for the parasite should be part of the investigative procedures in children with chronic diarrhoea. Images Figure 4 PMID:1398230

    Campylobacter jejuni is an important cause of acute bacterial diarrhoea. In developing countries like India, children gain immunity early during infancy. However, the incidence is higher in non-immune hosts. Antibiotic use destabilizes the gut flora and can inhibit the local immune responses, thereby compromising resistance to a variety of infections. It is not yet known whether antibiotic intake can also precipitate C. jejuni enteritis as the infectious dose is low and attack rates are high. We made a preliminary study to determine the prevalence of C. jejuni in hospitalized patients receiving antibiotics for various ailments. One hundred and thirty eight stool samples submitted for Clostridium difficile toxin assay were additionally cultured for C. jejuni in blood-free campylobacter selectivity agar. All suspected colonies were subjected to Gram staining, oxidase, catalase and nalidixic acid sensitivity tests. Confirmation of C. jejuni was done by the hippurate hydrolysis test. Of the 138 faecal samples investigated, 14 (10.1%) grew C. jejuni and 11 of them belonged to adults. Two of these 14 samples were also positive for C. difficile toxin. Though not as yet reported, C. jejuni may also be involved in antibiotic associated diarrhoea due to lowered immunity in the host. It may cause enteritis either by itself or in synergy with C. difficile infection.

    We undertook a nine month study to define the frequency of parasitic infections in adults with diarrhoea presenting at the medical filter clinic and the Dermatovenereology clinic of the University Teaching Hospital in Lusaka, Zambia. A total of 287 patients with diarrhoea were enrolled in the study; 130 from the adult medicine filter clinic recruitment consulting room and 157 patients from the Dermatovenereology clinic. Of 130 patients from the adult filter clinic, 85 (65%) were HIV-seropositive and 45 (35%) were seronegative for HIV. Out of 85 HIV-seropositive patients, 58 (68.2%) had acute diarrhoea and 27 (31.8%) had chronic diarrhoea. Of the 45 HIV-seronegative patients, 35 (77%) had acute diarrhoea and 10 (23%) had chronic diarrhoea. All of the 157 patients recruited from the Dermatovenereology clinic were HIV-seropositive. Of these, 97 (62%) had chronic diarrhoea; 7 (4%) had acute diarrhoea, and 53 (34%) patients had no diarrhoea. The common parasites detected were Ascaris lumbricoides, hookworm, Entamoeba coli, and Cryptosporidium spp. Isospora belli and Cryptosporidium spp were seen only in the HIV-seropositive group. In the Dermatovenereology clinic there was a statistically significant difference between parasite detection rate of Isospora belli and Cryptosporidium spp in HIV-seropositive patients with chronic diarrhoea compared to asymptomatic HIV-seropositive individuals P < 0.01 and p = 0.05, respectively). A significant difference in detection rates of Entamoeba coli was seen between the HIV-seropositive group in the Dermatovenereology clinic [17 (10.8%) out of 157] compared to 1 (1.5%) out of 85 in the adult medicine filter clinic.(ABSTRACT TRUNCATED AT 250 WORDS)

    Exposure to adult smoking can have deleterious effects on children. Interventions that assist families with smoking cessation/reduction and environmental tobacco smoke (ETS) avoidance can improve child health outcomes and reduce the risk of smoking initiation. The purpose of this review was to describe the state of the science of interventions with families to promote smoke-free home environments for infants and young children, including parent smoking reduction and cessation interventions, ETS reduction, and anti-smoking socialisation interventions, using the socio-ecological framework as a guide. A systematic review of peer-reviewed articles identified from journal databases from 2000 to 2014 was undertaken. Of 921 articles identified, 28 were included in the review. Considerable heterogeneity characterised target populations, intervention types, complexity and intensity, precluding meta-analysis. Few studies used socio-ecological approaches, such as family theories or concepts. Studies in early parenthood (child age newborn to one year) tended to focus on parent smoking cessation, where studies of families with children aged 1-5 years were more likely to target household SHSe reduction. Results suggest that interventions for reduction in ETS may be more successful than for smoking cessation and relapse prevention in families of children aged less than 5 years. There is a need for a range of interventions to support families in creating a smoke free home environment that are both tailored and targeted to specific populations. Interventions that target the social and psychodynamics of the family should be considered further, particularly in reaching vulnerable populations. Consideration is also required for approaches to interventions that may further stigmatise families containing smokers. Further research is required to identify successful elements of interventions and the contexts in which they are most effective.

    In 2012, the World Health Organization adopted a resolution on maternal, infant and young child nutrition that included a global target to reduce by 40% the number of stunted under-five children by 2025. The target was based on analyses of time series data from 148 countries and national success stories in tackling undernutrition. The global target translates to a 3.9% reduction per year and implies decreasing the number of stunted children from 171 million in 2010 to about 100 million in 2025. However, at current rates of progress, there will be 127 million stunted children by 2025, that is, 27 million more than the target or a reduction of only 26%. The translation of the global target into national targets needs to consider nutrition profiles, risk factor trends, demographic changes, experience with developing and implementing nutrition policies, and health system development. This paper presents a methodology to set individual country targets, without precluding the use of others. Any method applied will be influenced by country-specific population growth rates. A key question is what countries should do to meet the target. Nutrition interventions alone are almost certainly insufficient, hence the importance of ongoing efforts to foster nutrition-sensitive development and encourage development of evidence-based, multisectoral plans to address stunting at national scale, combining direct nutrition interventions with strategies concerning health, family planning, water and sanitation, and other factors that affect the risk of stunting. In addition, an accountability framework needs to be developed and surveillance systems strengthened to monitor the achievement of commitments and targets.

    Each year, more than 300,000 children in India under the age of five years die from diarrheal diseases. Clean piped water and improved sanitation are known to be effective in reducing the mortality and morbidity burden of diarrhea but are not yet available to close to half of the Indian population. In this paper, we estimate the health benefits (reduced cases of diarrheal incidence and deaths averted) and economic benefits (measured by out-of-pocket treatment expenditure averted and value of insurance gained) of scaling up the coverage of piped water and improved sanitation among Indian households to a near-universal 95% level. We use IndiaSim, a previously validated, agent-based microsimulation platform to model disease progression and individual demographic and healthcare-seeking behavior in India, and use an iterative, stochastic procedure to simulate health and economic outcomes over time. We find that scaling up access to piped water and improved sanitation could avert 43,352 (95% uncertainty range [UR] 42,201-44,504) diarrheal episodes and 68 (95% UR 62-74) diarrheal deaths per 100,000 under-5 children per year, compared with the baseline. We estimate a saving of (in 2013 US$) $357,788 (95% $345,509-$370,067) in out-of-pocket diarrhea treatment expenditure, and $1646 (95% UR $1603-$1689) in incremental value of insurance per 100,000 under-5 children per year over baseline. The health and financial benefits are highly progressive, i.e. they reach poorer households more. Thus, scaling up access to piped water and improved sanitation can lead to large and equitable reductions in the burden of childhood diarrheal diseases in India.

    Piglet neonatal diarrhoea is an important issue in modern pig production and is linked to increased mortality and poor growth rates, affecting long-term pig health, increasing use of medication and cost of production. Saccharomyces cerevisiae var. boulardii (SB) is a probiotic yeast with documented clinical efficacy in the prevention and treatment of diarrhoeal diseases in humans. The objectives of the current study were to evaluate the effect of SB on occurrence and severity of neonatal diarrhoea in piglets, mortality and growth rate. Forty-six litters (606 piglets) were randomly allocated to a control or SB treatment (n=23 per treatment). Within 24 h of farrowing, piglets assigned to the SB treatment received a single oral dose of a paste containing 3.3×10(9) CFU of SB CNCM I-107(9). Piglets from the control litters received a placebo paste. Piglet weight, mortality and diarrhoea were recorded up to day 7 of age. It was shown that numbers of diarrhoea days were significantly correlated with increased mortality rate and reduced weight gain (P<0.05). SB treatment had no effect on growth or mortality in diarrhoeic litters. However, SB-supplemented litters had significantly lower faecal scores, indicating firmer faeces (P<0.01) and fewer numbers of diarrhoeic days (P<0.01) during the 1(st) week of life. Reduction in the number of diarrhoeic litters compared with the control group was observed following the probiotic administration (P<0.05). These results highlight the detrimental effects of neonatal diarrhoea on pre-weaning performance and suggest that SB, by reducing diarrhoea duration and severity, has the potential of improving enteric health in the early stages of life in pigs.

    Acute bloody diarrhoea may be commonly encountered in the acute medical unit. Among young patients, the main differential diagnoses are acute infectious colitis, and first presentation of inflammatory bowel disease (IBD). A combination of clinical, laboratory, radiological, endoscopic and histological investigations are required to make the diagnosis. If inflammatory bowel disease is suspected, then the patient should be admitted to a specialist gastroenterology ward and receive input from the surgical team, IBD nurses and specialist stoma nurses. Intravenous steroid therapy for acute severe disease should be started before stool cultures are back unless there is a strong clinical suspicion of amoebiasis. All patients require thromboprophylaxis and close attention paid to fluid balance and nutritional requirements. Daily clinical review is required. The Travis criteria may be employed at day 3 to assess the likelihood of requiring surgery and plans for rescue therapy, medical or surgical should be made between day 3-7 if the patient is not responding adequately to initial medical therapy.

    Several aid groups have proposed strategies for allocating ready-to-use (therapeutic and supplementary) foods to children in developing countries. Analysis is needed to investigate whether there are better alternatives. We use a longitudinal dataset of 5,657 children from Bwamanda to construct a bivariate time-series model that tracks each child's height-for-age z score (HAZ) and weight-for-height z score (WHZ) throughout the first 5 y of life. Our optimization model chooses which individual children should receive ready-to-use therapeutic or supplementary food based on a child's sex, age, HAZ, and WHZ, to minimize the mean number of disability-adjusted life years (DALYs) per child during 6-60 mo of age [which includes childhood mortality calculated from a logistic regression and the lifelong effects of stunting (i.e., low HAZ)] subject to a budget constraint. Compared with the strategies proposed by the aid groups, which do not use HAZ information, the simple strategy arising from our analysis [which prioritizes children according to low values of a linear combination of HAZ, WHZ, and age and allocates the entire budget to therapeutic (i.e., 500 kcal/d) food for the prioritized children] reduces the number of DALYs by 9% (for the same budget) or alternatively incurs the same number of DALYs with a 61% reduction in cost. Whereas our qualitative conclusions appear to be robust, the quantitative results derived from our analysis should be treated with caution because of the lack of reliable data on the impact of supplementary food on HAZ and WHZ, the application of our model to a single cohort of children and the inclusion and exclusion errors related to imperfect food targeting.

  1. Costs of treating diarrhoea in a children's hospital in Mexico City.

    The treatment received by children aged under 5 years with diarrhoea was studied in the Hospital Infantil de México (Federico Goméz), Mexico City. The costs of treatment were calculated and estimates were made of how these had changed since the establishment of an oral rehydration unit in the hospital in 1985. The results indicate that drug treatment of outpatients was generally appropriate and inexpensive. In contrast, the cost of drugs for inpatients was considerably higher. The seriousness of the cases justified much of this additional expense for inpatients, but there is evidence that the costs could be reduced further without jeopardizing the quality of the care. Diagnostic tests were relatively expensive, frequently failed to identify diarrhoeal etiology, and their results correlated poorly with the treatment prescribed. The oral rehydration unit resulted in significant savings by causing a 25% fall in the number of inpatients with diarrhoea. PMID:2766450

    Introduction Administration of some probiotics appears to reduce the risk of antibiotic-associated diarrhoea (AAD). The effects of probiotics are strain-specific, thus, the efficacy and safety of each probiotic strain should be established separately. We aim to assess the effects of Lactobacillus reuteri DSM 17938 administration for the prevention of diarrhoea and AAD in children. Methods and analysis A total of 250 children younger than 18 years treated with antibiotics will be enrolled in a double-blind, randomised, placebo-controlled trial in which they will additionally receive L. reuteri DSM 17938 at a dose 108 colony-forming units or an identically appearing placebo, orally, twice daily, for the entire duration of antibiotic treatment. The primary outcome measures will be the frequencies of diarrhoea and AAD. Diarrhoea will be defined according to 1 of 3 definitions: (1) ≥3 loose or watery stools per day for a minimum of 48 hours during antibiotic treatment; (2) ≥3 loose or watery stools per day for a minimum of 24 hours during antibiotic treatment; or (3) ≥2 loose or watery stools per day for a minimum of 24 hours during antibiotic treatment. AAD will be diagnosed in cases of diarrhoea, defined clinically as above, caused by Clostridium difficile or for otherwise unexplained diarrhoea (ie, negative laboratory stool tests for infectious agents). Ethics and dissemination The Bioethics Committee approved the study protocol. The findings of this trial will be submitted to a peer-reviewed paediatric journal. Abstracts will be submitted to relevant national and international conferences. Trial registration number NCT02871908. PMID:28057659

    Acute diarrhoea remains a major public health challenge in developing countries. We examined the role of a probiotic in the prevention of acute diarrhoea to discover if there was an effect directed towards a specific aetiology. A double-blind, randomized, controlled field trial involving 3758 children aged 1-5 years was conducted in an urban slum community in Kolkata, India. Participants were given either a probiotic drink containing Lactobacillus casei strain Shirota or a nutrient drink daily for 12 weeks. They were followed up for another 12 weeks. The primary outcome of this study was the occurrence of first episodes of diarrhoea. We assessed this during 12 weeks of intake of study agent and also for 12 weeks of follow-up. There were 608 subjects with diarrhoea in the probiotic group and 674 subjects in the nutrient group during the study period of 24 weeks. The level of protective efficacy for the probiotic was 14% (95% confidence interval 4-23, P<0·01 in adjusted model). The reduced occurrence of acute diarrhoea in the probiotic group compared to nutrient group was not associated with any specific aetiology. No adverse event was observed in children of either probiotic or nutrient groups. The study suggests that daily intake of a probiotic drink can play a role in prevention of acute diarrhoea in young children in a community setting of a developing country.

    Circulating autoantibodies to enterocytes were detected by indirect immunofluorescence in 14 out of 25 patients with idiopathic protracted diarrhoea of infancy. Similar specificities were not found in 50 control children with nongastroenterological disorders. The immunofluorescence pattern was more accentuated on the apical border of mature enterocytes. Enterocyte autoantibodies were mainly of IgG class (13/14), but 11 sera were positive for IgM and IgA classes, and five out of 14 positive sera also had the ability to fix complement. Absorption of sera positive for autoantibodies with an IgA coupled immunoabsorbent did not modify the intensity of the staining, indicating that these antibodies were not directed against secretory IgA. High titres and the complement fixing ability of enterocyte autoantibodies indicated a poorer prognosis despite the use of immunosuppressive drugs. Organ specific and non-organ specific autoimmune diseases or corresponding autoantibodies or both were often found in children with enterocyte autoantibodies and their family. These data show the existence of an autoimmune variant of protracted diarrhoea of infancy, despite the rare occurrence of autoimmune diseases in childhood. Images p1134-a PMID:3094805

    Objective Racecadotril is an antisecretory agent that can prevent fluid/electrolyte depletion from the bowel as a result of acute diarrhoea without affecting intestinal motility. An up-to-date systematic review is indicated to summarise the evidence on racecadotril for the treatment of acute diarrhoea in children. Design A Cochrane format systematic review of randomised controlled trials (RCTs). Data extraction and assessment of methodological quality were performed independently by two reviewers. Methodological quality was assessed using the Cochrane risk of bias tool. Patients Children with acute diarrhoea, as defined by the primary studies. Interventions RCTs comparing racecadotril with placebo or other interventions. Main outcome measurs Duration of illness, stool output/volume and adverse events. Results Seven RCTs were included, five comparing racecadotril with placebo or no intervention, one with pectin/kaolin and one with loperamide. Moderate to high risk of bias was present in all studies. There was no significant difference in efficacy or adverse events between racecadotril and loperamide. A meta-analysis of three studies with 642 participants showed significantly shorter duration of symptoms with racecadotril compared with placebo (mean difference −53.48 h, 95% CI −65.64 to −41.33). A meta-analysis of five studies with 949 participants showed no significant difference in adverse events between racecadotril and placebo (risk ratio 0.99, 95% CI 0.73 to 1.34). Conclusions There is some evidence that racecadotril is more effective than placebo or no intervention in reducing the duration of illness and stool output in children with acute diarrhoea. However, the overall quality of the evidence is limited due to sparse data, heterogeneity and risk of bias. Racecadotril appears to be safe and well tolerated. PMID:26715673

  7. The importance of breastfeeding in rotaviral diarrhoeas.

    Globally, rotaviral vaccines in use today have contributed to the reduction of the incidence of rotaviral diarrhoeas. Despite the substantial protection conferred by the current vaccines against the rotaviral strains, it is only prudent to recognise that other protective factors, like breastfeeding, also provide some degree of protection against this disease. This article has attempted to review some important mechanisms of protection in breast milk against the rotaviruses and highlight the oft forgotten non-immunoglobulin fraction in breast milk as an additional tool of protection against rotavirus disease. The adaptive capacity of breast milk to environment is another compelling reason to continue breastfeeding as it can usefully complement and be significant in the use of many vaccines. Vital immunoprotective constituents in breast milk beneficially protect the infant by initiating and strengthening many immune responses and should be borne in mind as essential tools of defence even in an era where vaccines play a pivotal role in the combat against certain diseases. It is impressive that besides nutritive advantages, the suckling infant enjoys appreciable immunoprotection via exclusive breastfeeding.

    Childhood lead exposure and poisoning near primary lead smelters continues in developed and developing countries. In the United States, the problem of lead poisoning in children caused by smelter emissions was first documented in the early 1970s. In 1978, Environmental Protection Agency set National Ambient Air Quality Standards for lead. Attainment of this lead standard in areas near operating lead smelters took twenty to thirty years. Childhood lead exposure and poisoning continued to occur after the lead National Ambient Air Quality Standards were set and before compliance was achieved. This article analyzes and discusses the factors that led to the eventual achievement of the 1978 lead National Ambient Air Quality Standards near primary smelters and the reduction of children's blood lead levels in surrounding communities. Factors such as federal and state regulation, monitoring of emissions, public health activities such as blood lead surveillance and health education, relocation of children, environmental group and community advocacy, and litigation all played a role.

    Probiotic bacterium Lactobacillus rhamnosus GG (LGG) has been demonstrated to adhere to pig intestinal mucus, and is able to displace and inhibit pathogens, including Escherichia coli (E. coli), in vitro. However, currently there are few data concerning the effects of LGG on piglet health. The objectives of this study were to assess the effectiveness of LGG in reducing the incidence and severity of post-weaning diarrhoea in piglets, and to investigate its mechanisms of action. Eighteen weaned barrows were allocated to nonchallenged control (NCN), challenged control (CCN) and LGG treatment (LGG) groups. Diarrhoea incidence was significantly lower in group LGG than group CCN after E. coli challenge. Faecal coliform bacteria counts were significantly increased, while lactobacilli and bifidobacteria counts were decreased, in group CCN compared with the other groups after challenge. In the jejunum and ileum, secretory immunoglobin A (SIgA) concentrations were significantly higher in group LGG than in group CCN. In group LGG, administration of short-term LGG before E. coli infection attenuated the elevation of serum IL-6 induced by E. coli. Significantly higher concentrations of TNF-alpha were observed in group LGG than NCN and CCN at 6h. IL-1beta concentrations in group NCN were significantly higher than LGG at 6h and higher than CCN at 24h. In conclusion, LGG was effective in ameliorating diarrhoea in post-weaning piglets induced by E. coli K88, possibly via modulation of intestinal microflora, enhancement of intestinal antibody defence, and regulation of production of systemic inflammatory cytokines.

    Tannins, a group of major active components of Chinese rhubarb and widely distributed in nature, have a significant antidiarrhoeal activity. Aquaporins (AQPs) 2 and 3 play important roles in regulating water transfer during diarrhoea. The present study aims to determine the effect of the total tannins extract of rhubarb on aquaporins (AQPs) 2 and 3 in diarrhoea mice and HT-29 cells both induced by magnesium sulphate (MgSO4). Our results showed that rhubarb tannins extract (RTE) significantly decreased the faecal water content in colon and evaluation index of defecation of diarrhoea mice. Interestingly, RTE could markedly reduce the mRNA and protein expression levels of AQPs 2 and 3 in apical and lateral mucosal epithelial cells in the colons of diarrhoea mice and HT-29 cells both induced by MgSO4 in a dose-dependent manner. Furthermore, RTE suppressed the production of cyclic monophosphate- (cAMP-) dependent protein kinase A catalytic subunits α (PKA C-α) and phosphorylated cAMP response element-binding protein (p-CREB, Ser133) in MgSO4-induced HT-29 cells. Our data showed for the first time that RTE inhibit AQPs 2 and 3 expression in vivo and in vitro via downregulating PKA/p-CREB signal pathway, which accounts for the antidiarrhoeal effect of RTE.

    Bovine viral diarrhoea virus (BVDV) is the most prevalent infectious disease of cattle. It causes financial losses from a variety of clinical manifestations and is the subject of a number of mitigation and eradication schemes around the world. The pathogenesis of BVDV infection is complex, with infection pre- and post-gestation leading to different outcomes. Infection of the dam during gestation results in fetal infection, which may lead to embryonic death, teratogenic effects or the birth of persistently infected (PI) calves. PI animals shed BVDV in their excretions and secretions throughout life and are the primary route of transmission of the virus. These animals can usually be readily detected by virus or viral antigen detection assays (RT-PCR, ELISA), except in the immediate post-natal period where colostral antibodies may mask virus presence. PI calves in utero (the 'Trojan cow' scenario) currently defy detection with available diagnostic tests, although dams carrying PI calves have been shown to have higher antibody levels than seropositive cows carrying non-PI calves. Acute infection with BVDV results in transient viraemia prior to seroconversion and can lead to reproductive dysfunction and immunosuppression leading to an increased incidence of secondary disease. Antibody assays readily detect virus exposure at the individual level and can also be used in pooled samples (serum and milk) to determine herd exposure or immunity. Diagnostic tests can be used to diagnose clinical cases, establish disease prevalence in groups and detect apparently normal but persistently infected animals. This review outlines the pathogenesis and pathology of BVD viral infection and uses this knowledge to select the best diagnostic tests for clinical diagnosis, monitoring, control and eradication efforts. Test methods, types of samples and problems areas of BVDV diagnosis are discussed.

    Diarrhoeal diseases are common in Djakarta, Indonesia, especially among infants and young children. A study has been made of possible bacterial and parasitic causes of outbreaks in a group of 156 infants in a crowded area of the city. Before the study was complete, 60 infants had left the area and 30 had died; diarrhoea was probably the direct or indirect cause of 13 of the deaths. Diarrhoea was associated with pathogenic Escherichia coli in about 20% of the cases studied; other causes of diarrhoea were Shigella, less frequent, and rare among infants below the age of 6 months; Salmonella, insignificant; Giardia lamblia, common, but not usually associated with diarrhoea; Entamoeba histolytica and Isospora belli, relatively rare. The role of Trichuris trichiura was probably important, but was difficult to assess. Many diarrhoea cases were not associated with either pathogenic bacteria or parasites. Other potential causes, not considered in this study, include enteropathogenic virus infection, parenteral infections, faulty diet and malnutrition. Further investigation is considered desirable.

    There is insufficient evidence to confirm the association between breastfeeding and allergic outcomes later in life. This study aimed to determine the relationships between different breastfeeding patterns and allergen sensitizations and risk of developing atopic diseases in early childhood. A total of 186 children from a birth cohort in the Prediction of Allergies in Taiwanese Children study for a 4-year follow-up period were enrolled. Total serum immunoglobulin E (IgE) levels and specific IgE antibodies against food and inhalant allergens were measured sequentially at 6 months as well as at 1, 1.5, 2, 3, and 4 years of age. A significantly lower prevalence of milk sensitization was found in children at ages 1 and 1.5 years who were exclusively or partially breastfed for ≥6 months. Breastfeeding ≥6 months was significantly associated with a reduced risk of developing eczema but not allergic rhinitis and asthma at ages 1 and 2 years. Compared with exclusive breastfeeding ≥6 months, partial breastfeeding <6 months was significantly associated with an increased risk of developing eczema at ages 1 and 2 years. As with exclusive breastfeeding, partial breastfeeding for at least 6 months appears to be associated with a reduced prevalence of milk sensitization as well as a reduced risk of developing eczema in early childhood.

    Stunting is associated with deficits in cognition and school achievement from early childhood to late adolescence; however, there has been little investigation of emotional and behavioral outcomes. The objective of this study was to determine whether linear growth retardation (stunting) in early childhood is associated with poorer psychological functioning in late adolescence. The study was a prospective cohort study of stunted and nonstunted children. Participants were identified at age 9-24 mo by a survey of poor neighborhoods in Kingston, Jamaica, and a 2-y intervention trial of supplementation and stimulation was conducted in the stunted children. Psychological functioning was assessed at age 17 y in 103 of 129 stunted children enrolled and 64 of 84 nonstunted participants. Anxiety, depressive symptoms, self-esteem, and antisocial behavior were reported by participants using interviewer-administered questionnaires and attention deficit, hyperactivity, and oppositional behavior were reported by parent interviews. The stunted participants reported significantly more anxiety (regression coefficient = 3.03; 95% CI = 0.99, 5.08) and depressive symptoms (0.37; 95% CI = 0.01, 0.72) and lower self-esteem (-1.67; 95% CI = -0.38, -2.97) than nonstunted participants and were reported by their parents to be more hyperactive (1.29; 95% CI = 0.12, 2.46). Effect sizes were 0.4-0.5 SD. Participants who received stimulation in early childhood differed from the nonstunted group in hyperactivity only. Children stunted before age 2 y thus have poorer emotional and behavioral outcomes in late adolescence. The findings expand the range of disadvantages associated with early stunting, which affects 151 million children <5 y old in developing countries.

    Despite preliminary evidence, the role of probiotic and synbiotic in treatment of the atopic dermatitis has shown varying results. We aimed to evaluate whether synbiotic supplementation decrease severity of atopic dermatitis (AD) in childhood. In a randomized double blind-placebo controlled trial, we evaluated the synbiotic supplementation efficiency on the treatment of atopic dermatitis. Infants aged 1-36 months with moderate to severe atopic dermatitis were randomized (n=41) and received either synbiotic (probiotic plus prebiotic) (n=20) or placebo (n=21) daily as a powder for two months. Emollient (Eucerin) and topical corticosteroid (Hydrocortisone) were permitted. Children were scored for severity of atopic dermatitis (SCORAD). Also allergen Skin Prick Tests (SPT), IgE blood level and eosinophil count were measured at first visit. Patients' SCORAD were reevaluated at the end of intervention. We followed 36 out of 41 subjects for two months (drop out rate = 9%). In the whole group, the mean Total SCORAD (at base line 40.93) decreased by 56% (p=0.00). The mean Objective SCORAD (at base line 31.29) decreased by 53% (p=0.00). There was no significant difference in the mean decrease of total SCORAD between placebo (22.3) and synbiotic groups (24.2). There was also no difference between two intervention groups in the mean decrease of total SCORAD regarding to different demographic, clinical and para clinical subgroups. This study could not confirm synbiotic as an effective treatment for childhood atopic dermatitis and further studies are needed. These findings challenge the role of synbiotics in the treatment of childhood atopic dermatitis.

    Fatty acid amide hydrolase (FAAH) inhibitors are addressed for promising anxiolytics, but human studies on genetically reduced FAAH activity, stress and affective phenotypes are scarce. We investigated the effect of a functional polymorphism of FAAH (FAAH C385A or rs324420; low FAAH activity and high anandamide concentration are associated with the A allele) together with childhood adversity on the anxious and depressive phenotypes in 858 subjects from the general population. Phenotypes were measured by the Zung Self-Rating Depression Scale (ZSDS), the depression and anxiety subscales of the Brief Symptom Inventory (BSI-DEP, BSI-ANX) and the State-Trait Anxiety scales (STAI-S, STAI-T). Childhood Adversity Questionnaire (CHA) was used to assess early life traumas. Frequency of the A allele was greater among subjects with high ZSDS scores compared to the CC genotype. Furthermore, FAAH C385A and the CHA have shown a robust gene-environment interaction, namely, significantly higher anxiety and depression scores were exhibited by individuals carrying the A allele if they had high CHA scores compared to CC carriers. These data provided preliminary evidence that genetically reduced FAAH activity and repetitive stress in the childhood are associated with increased vulnerability for anxiety and depression in later life. Our results together with earlier experimental data suggest that permanently elevated anandamide level together with early life stress may cause a lifelong damage on stress response probably via the downregulation of CB1R during the neurodevelopment in the brain. It may also point to pharmacogenomic consequences, namely ineffectiveness or adverse effects of FAAH inhibitors in this subpopulation.

    Tropheryma whipplei has been hypothesized to be able to cause diarrhoea, but data from young children are scarce. In this hospital-based case-control study 534 stool samples of children aged between 2 months and 15 years from rural Ghana were analysed for the presence of T. whipplei. Overall stool prevalence of T. whipplei was high (27.5%). Although there was no difference in T. whipplei carriage overall between cases and controls, cases aged between 0 and 12 months carried T. whipplei in their stool twice as often as controls without diarrhoea. The results from this study may support the hypothesis that T. whipplei can cause diarrhoea in first-time infection.

    Children with severe acute malnutrition complicated by diarrhoea require special care due to their unique physiological vulnerability and increased mortality risks. A systematic literature review (1950-2013) was conducted to identify the most effective diagnostic and therapeutic measures for the community-based management of severely malnourished children with diarrhoea. No studies directly addressed this question, so the search was broadened to include inpatient care. Of the 129 studies identified, 32 were selected for full review and found to contain varying degrees of indirectness, inconsistency and bias. Evidence from diagnostic studies point to the use of both prolonged and persistent diarrhoea as morbidity markers, rapid hypoglycaemia diagnosis and the frequent aetiological role of Cryptosporidium. Therapeutic studies suggest benefits from routine antiparasitic medication and feeding regimens with ready-to-use-therapeutic foods, lactose-free diets and zinc supplementation. Existing rehydration treatment guidelines were affirmed, but the utility of glutamine and low osmolarity feeds were inconclusive.

    Recently a parvovirus called bufavirus (BuV) has been implicated as a causative agent of diarrhoea. To further reveal the epidemiology and genetic characteristics of BuV, this study was performed in Turkish children with diarrhoea. BuV was detected in 1.4% (8/583) of stool samples. All stool samples from healthy children (n = 148) were negative for BuV. Diarrhoea in BuV-positive patients was severe and occurred mainly during the colder months of the year. Complete genome sequences were generated from four BuVs. Only BuV3 was found, which was genetically and phylogenetically similar to Bhutanese BuV3, indicating that BuV3 is prevalent in Asian countries.

Her diagnosis was congenital chloride diarrhoea (CCD) with raised level of chloride (>90 mmol/L) in stool in the absence of cystic fibrosis. Management of CCD included replacement of NaCl, KCl, and correction of dehydration. Diarrhoea of the patient was resolved with Captopril, which was initially provided to the patient for managing heart failure. To our knowledge, this is the first reported case of CCD that shows the beneficial effect of Captopril. Therefore, we suggest that further study is warranted as to the potential for Captopril as additional option in the treatment for CCD. We present this case report with the informed consent of the patient's guardian.

    An 81-year-old lady was admitted to our hospital with a 3-year history of noninfective diarrhoea and recurrent syncopal events over the last 3 months. Her initial electrocardiogram (ECG) revealed trigeminy and prolonged QTc interval. She had a structurally normal heart with no coronary artery disease. Investigations revealed low potassium at 3.0 mmol/L. Sigmoidoscopy and colonoscopy suggested a possible diagnosis of diverticulitis. Soon after admission she had an unresponsive episode with spontaneous recovery. Telemetry and Holter analysis confirmed multiple episodes of polymorphic ventricular tachycardia (Torsade de Pointes). Following electrolyte supplementation the episodes of polymorphic VT improved. Due to the protracted nature of the diarrhoea, the recurrent syncopal events, and recurrent hypokalaemia documented over recent years, an Implantable Cardioverter Defibrillator (ICD) was sanctioned by the multidisciplinary team (MDT). In summary, chronic diarrhoea may result in life threatening polymorphic VT due to hypokalaemia and QTc prolongation. In these patients an ICD may be considered. PMID:27313906

    Rotavirus (RV) has been shown to infect and stimulate secretion of serotonin from human enterochromaffin (EC) cells and to infect EC cells in the small intestine of mice. It remains to identify which intracellularly expressed viral protein(s) is responsible for this novel property and to further establish the clinical role of serotonin in RV infection. First, we found that siRNA specifically silencing NSP4 (siRNANSP4) significantly attenuated secretion of serotonin from Rhesus rotavirus (RRV) infected EC tumor cells compared to siRNAVP4, siRNAVP6 and siRNAVP7. Second, intracellular calcium mobilization and diarrhoeal capacity from virulent and avirulent porcine viruses correlated with the capacity to release serotonin from EC tumor cells. Third, following administration of serotonin, all (10/10) infants, but no (0/8) adult mice, responded with diarrhoea. Finally, blocking of serotonin receptors using Ondansetron significantly attenuated murine RV (strain EDIM) diarrhoea in infant mice (2.9 vs 4.5 days). Ondansetron-treated mice (n = 11) had significantly (p < 0.05) less diarrhoea, lower diarrhoea severity score and lower total diarrhoea output as compared to mock-treated mice (n = 9). Similarly, Ondansetron-treated mice had better weight gain than mock-treated animals (p < 0.05). A most surprising finding was that the serotonin receptor antagonist significantly (p < 0.05) also attenuated total viral shedding. In summary, we show that intracellularly expressed NSP4 stimulates release of serotonin from human EC tumor cells and that serotonin participates in RV diarrhoea, which can be attenuated by Ondansetron.

    As part of a Congressionally mandated report on U.S. childhood lead poisoning prepared by the Federal government (U.S. Agency for Toxic Substances and Disease Registry [ATSDR]), the authors have analyzed the relative effectiveness of measures to reduce source-specific lead exposure of U.S. children. An integrated overview of this analysis is presented in this article. Two national actions, the Federally mandated phasedown of lead in gasoline by the U.S. Environmental Protection Agency and the voluntary phasedown of lead use in domestic food can production, are examples of centrally directed initiatives that have been relatively successful in limiting childhood lead exposure in the U.S. Efforts to abate lead-based paint exposure of children have largely failed. This is especially true for the nation's 21 million residential units with the highest lead content paint. Similarly, abatement of lead exposure from contaminated dusts and soils has generally been unsuccessful. Comprehensive measures to reduce lead exposure from drinking water in residences and public facilities, e.g., elementary schools, are only now being promulgated or implemented. The full extent of their effectiveness remains to be demonstrated. There are many miscellaneous but potentially severe exposure sources that are difficult to control but require attention, such as poorly glazed foodware and ethno-specific preparations. PMID:2088738

    Travellers' diarrhoea is the most likely cause for disturbing travel arrangements. At an average, 30-40% of tourists are concerned, depending on the travel destination. Due to the high impact on the travellers' health this topic is still of utmost importance in travel medicine. A wide spectrum of enteropathogens can be accountable, with enterotoxigenic Escherichia coli being the major causing pathogen among other bacteria, parasites and viruses. Here we discuss advantages and disadvantages of different prophylactic measures against travellers' diarrhoea. The effectiveness but also the relevance of hygiene education, vaccination and antibiotic or probiotic application will be discussed in the context of the travellers' different risk profiles.

  6. Prescription of fixed dose combination drugs for diarrhoea.

    2007-01-01

    Fixed-dose combinations (FDCs) of an antiprotozoal and an antibacterial, for treatment of diarrhoea, have been available in the Indian pharmaceutical market for about a decade. There is little evidence to substantiate this combination therapy. We evaluated 2,163 physician prescriptions for diarrhoea and found that 59 per cent of prescriptions were for FDCs. This is unethical because prescribing such combinations exposes a patient to higher risks of adverse drug reactions and also increases the chances of drug resistance. Physicians' prescribing practices in India are influenced by socioeconomic factors and the pharmaceutical industry's marketing techniques that include giving incentives to physicians to prescribe certain drugs.

    In order to establish the mechanism of spray dried plasma powder (SDPP) in improving pig health and performance, a diet containing either 8% SDPP, spray dried immune plasma powder (SDIPP), or control protein (soybean and whey) ration was fed to piglets in an experimental model of enterotoxigenic Escherichia coli F4 (ETEC) post-weaning diarrhoea (PWD). SDIPP was obtained from pigs immunized with a vaccine containing ETEC fimbrial subunit F4 and heat-labile toxin (LT), and SDPP from non-immunized controls. Average daily growth (ADG) was determined, and daily samples of rectal faeces were assessed for diarrhoea (as percentage of dry matter), and ETEC excretion (in CFU/g). SDPP and SDIPP significantly (p<0.05) reduced diarrhoea, and SDIPP significantly reduced ETEC excretion. ADG was not significantly (p>0.05) affected. After the experiment, 30% of piglets tested F4 receptor positive (F4R+). A significant correlation between F4R status and morbidity was found. In F4R+ animals, SDIPP significantly improved diarrhoea and ADG, and decreased ETEC excretion, and SDPP significantly improved diarrhoea and ADG. Surprisingly, SDPP reduced diarrhoea in F4R+ animals without significant reduction of ETEC excretion, which is most likely related to the presence of anti-LT antibodies in SDPP. The results show that oral protection against ETEC by SDPP is attributable to spontaneous antibodies, in this case anti-LT antibodies. Furthermore, the results indicate that the combination of anti-LT and anti-F4 antibodies as in SDIPP is most effective in ETEC prevention. Finally, the F4R distribution in the herd should be taken into account to correctly assess efficacy.

    A longitudinal cohort study was conducted at Camp Hospital Batagram in August 2006 to ascertain the effect of Zinc utilization in tablet and suspension formulations on the frequency and recovery rates of diarrhoea among young children in the emergency settings of earthquake affected region of Pakistan. Two hundred patients were recruited and followed up, the patients were allocated either of the 2 groups i.e. A (zinc in tablets form) and B (zinc in suspension form). Both groups also received WHO recommended treatment for diarrhoea. Most of the cases recovered from the illness within 3 days after presentation. Significant p-values were established among Zinc use and reduction in frequency of stools on Day 2 and 3, with better outcome in group B. The study supports the notion that zinc reduces the frequency and improves recovery rates of diarrhoea in any form and has better compliance and outcomes with the use in suspension form.

    The aerobic and anaerobic bacterial microflora of the upper gastrointestinal tract in infants with protracted diarrhoea has been described and compared with a group of control infants without diarrhoea. The duodenal juice of patients with protracted diarrhoea was rarely sterile and was characterized by an increase in numbers and types of microorganisms and by the presence of coliforms, particularly Esch. coli. In individual patients the same serotypes of Esch. coli were found throughout the intestinal tract. The presence of Esch. coli in the upper small intestine may be as important to the aetiology of protracted diarrhoea as it is to acute diarrhoea. PMID:4598080

    Diarrhoea is a widespread problem for sheep enterprises worldwide. A cross-sectional epidemiological study was conducted using a questionnaire to determine the prevalence of diarrhoea and associated risk factors where there was evidence of recent diarrhoea (active diarrhoea or fresh faecal soiling of breech fleece) for meat lambs on farms in southern Western Australia during 2010. The response rate was 41.4% (139/336). Evidence of recent diarrhoea was reported on 64.8% of farms, with a mean of 6.9% lambs affected per farm. Location of a farm and a higher annual rainfall were associated with an increased diarrhoea prevalence. Binary logistic regression analysis suggested that the drinking water source was associated with the incidence of diarrhoea, since lamb flocks supplied with dam water were 117 times (95% CI: 18.2, 754.8) more likely to have observed diarrhoea or fresh breech fleece faecal soiling than lamb flocks supplied with other sources of water. Faecal worm egg counts were used by 65% of respondents to determine whether an anthelmintic treatment was warranted and 74% of respondents administered a treatment to their meat lambs. In response to a range of diarrhoea scenarios presented to respondents (5%, 25% and 50% of the flock with evidence of recent diarrhoea), 15.1% would have elected to administer an anthelmintic treatment regardless of differences in prevalence.

    Although several studies show the vulnerability of human health to climate change, a clear comprehensive quantification of the increased health risks attributable to climate change is lacking. Even more complicated are assessments of adaptation measures for this sector. We discuss the impact of climate change on diarrhoea as a representative of a waterborne infectious disease affecting human health in the Ganges basin of northern India. A conceptual framework is presented for climate exposure response relationships based on studies from different countries, as empirical studies and appropriate epidemiological data sets for India are lacking. Four climate variables are included: temperature, increased/extreme precipitation, decreased precipitation/droughts and relative humidity. Applying the conceptual framework to the latest regional climate projections for northern India shows increases between present and future (2040s), varying spatially from no change to an increase of 21% in diarrhoea incidences, with 13.1% increase on average for the Ganges basin. We discuss three types of measures against diarrhoeal disease: reactive actions, preventive actions and national policy options. Preventive actions have the potential to counterbalance this expected increase. However, given the limited progress in reducing incidences over the past decade consorted actions and effective implementation and integration of existing policies are needed.

    In an operational research on the improvement of sanitation and water supply by an Indo-Dutch project at Mirzapur, UP, diarrhoeal morbidity was taken as an intermediate outcome variable for measuring the impact of the proposed intervention. In this study 350-410 under-five children were selected from 200 urban families of 3 slums and surveyed during 3 different seasons for 2 weekly recall of morbidity, treatment and feeding practices during diarrhoea. The prevalence of diarrhoea varied between 8.7% to 33%. Breast feeding was not restricted while other forms of feeding was continued in 57.1% to 66.3% of cases. Use of ORT increased significantly from 0% to 39.62% possibly as a result of health education. Reorientation of private practitioners to avoid use of unnecessary drug is suggested.

    Seven women spent an average of 127 days in hospital and were extensively investigated, including a laparotomy, before their complaints of abdominal pain, diarrhoea, and weight loss were shown to be due to excessive taking of laxatives. All denied taking laxatives and in none were the characteristic features of the effects of cathartics on the colon seen on sigmoidoscopy or radiological examination. Hypokalaemia and other electrolyte abnormalities were common and were thought to be due to a combination of severe diarrhoea and vomiting. The rectal mucosa was seen to be abnormal on biopsy only in the three patients who had taken senna preparations. The diagnosis was not easy and was finally established either by analysis of the urine and stools or by searching the patient's ward locker. PMID:4817188

    Campylobacter jejuni is one of the most common causes of bloody diarrhoea in the USA. We report a case of a young woman who presented with a clinical picture reminiscent of acute appendicitis. Ultrasonography and CT of the abdomen performed subsequently revealed evidence of colitis. Quite unexpectedly, she had no symptoms of diarrhoea and the stool Gram stain and culture were negative. Nevertheless, due to high clinical suspicion of infectious colitis, appendectomy was deferred. Blood culture was later reported positive for Campylobacter species and the patient responded to quinolones. With this case report we try to highlight one of the unusual presentations of C jejuni infection, closely mimicking acute appendicitis in the absence of classical symptoms of bacterial enteritis. In such cases, a high index of suspicion, astute history taking skills and the proper use of imaging studies can save the patient from the surgical knife.

    Background. Despite improvements in child health, Afghanistan still has a heavy burden of deaths due to preventable causes: 17% of under-5 deaths are due to pneumonia and 12% are due to diarrhoea. Objective. This article describes the situation of childhood pneumonia and diarrhoea in Afghanistan, including efforts to prevent, protect, and treat the two diseases. It estimates lives saved by scaling up interventions. Methods. A secondary analysis of data was conducted and future scenarios were modelled to estimate lives saved by scaling up a package of interventions. Results. The analysis reveals that 10,795 additional child deaths could be averted with a moderate scale-up of interventions, decreasing the under-five mortality rate in Afghanistan from 55 per 1,000 live births in 2015 to 40 per 1,000 in 2020. In an ambitious scale-up scenario, an additional 15,096 lives could be saved. There would be a 71% reduction in child deaths due to these two causes between 2016 and 2020 in the ambitious scenario compared to 47% reduction in the moderate scenario. Conclusion. Significant reductions in child mortality can be achieved through scale-up of essential interventions to prevent and treat pneumonia and diarrhoea. Strengthened primary health care functions and multisector collaboration on child health are suggested. PMID:28298932

    The clinical features of ulcerative colitis and Crohn's disease are similar to those of infections of the bowel, although their cause is uncertain. Many bacteria that cause intestinal diseases adhere to the gut mucosa, and adhesion of pathogenic Escherichia coli is resistant to D-mannose. The adhesive properties of isolates of E coli were assessed by assay of adhesion to buccal epithelial cells with mannose added. The isolates were obtained from patients with inflammatory bowel diseases (50 with a relapse of ulcerative colitis, nine with ulcerative colitis in remission, 13 with Crohn's disease, and 11 with infectious diarrhoea not due to E coli) and 22 controls. The median index of adhesion to buccal epithelial cells (the proportion of cells with more than 50 adherent bacteria) for E coli from patients with ulcerative colitis in relapse was significantly higher (43%) than that for controls (5%) and patients with infectious diarrhoea (14%). The index was not significantly different among isolates from patients with ulcerative colitis in relapse, Crohn's disease (53%), and ulcerative colitis in remission (30%). If an index of adhesion of greater than 25% is taken as indicating an adhesive strain 86% of isolates of E coli from patients with inflammatory bowel disease were adhesive compared with 27% from patients with infective diarrhoea and none from controls. The adhesive properties of the isolates from patients with inflammatory bowel disease were similar to those of pathogenic intestinal E coli, raising the possibility that they may have a role in the pathogenesis of the condition; the smaller proportion of adhesive isolates in patients with infective diarrhoea due to other bacteria suggests that the organism may be of primary importance rather than arising secondarily.

    No prospective studies including large numbers of dogs with acute haemorrhagic diarrhoea syndrome (AHDS) are published so far. The aim of this case-control study was to describe signalment, history, clinical signs, laboratory values and course of disease in dogs with AHDS. Dogs (108) with idiopathic acute haemorrhagic diarrhoea (<3 days) were prospectively enrolled. Clinical assessment was performed by calculation of the 'AHDS index' (0-18). The hospital population and 21 healthy dogs served as control groups. Dogs with AHDS had a significantly lower body weight (median 9.8 kg) and age (median five years) than other dogs of the hospital population (20 kg; 10 years) (P<0.001). Predisposed breeds were Yorkshire terrier, miniature pinscher, miniature schnauzer and Maltese. The syndrome was more likely to occur during winter. Vomiting preceded the onset of bloody diarrhoea in 80 per cent of dogs and haematemesis was observed in half of those cases. Median AHDS index at presentation was 12 (range 3-17). Haematocrit was generally high (median 57.1 per cent; range 33-76 per cent), but exceeded 60 per cent only in 31.4 per cent of dogs. Haematocrit of 48.1 per cent of dogs was above reference range, as was monocyte (50.0 per cent), segmented (59.6 per cent) and band neutrophil count (45.2 per cent). A rapid clinical improvement occurred during the first 48 hours.

    The weather of Saudi Arabia is hot and dry for most of the year. The country is devoid of surface water which often help the transmission of diarrhoeal diseases. Nevertheless, this country is not free from diarrhoeal diseases. The role of such factors as crowding, patterns of water use, sanitation, quality of housing, feeding practices and region of residence have not been adequately studied. The 1987 National Child Health Survey data were used to earmark the roles of the aforementioned determinants of diarrhoea in Saudi children aged below six. A stratified and representative sample of 8,566 married women living in rural and urban areas were interviewed by 120 female nurses. There were about two episodes of diarrhoea per child per year. Children aged 6 to 23 months had nearly double the prevalence rate of the older children. Children from rural areas and the southern region had higher rates than children from other areas. Children who were both breast and bottle fed, children of 1-4 member families and of families with 3 or more persons per room had higher prevalence rates. Children of families whose homes had earthen floors, those who used well water and those without toilet facilities who used open fields for defecation had significantly higher rates. In spite of adverse climate and little use of surface water these factors were significantly associated with higher prevalence rates of diarrhoea in Saudi children under six years of age.

    Antimicrobial peptides represent an important component of the innate immune defenses of living organisms, including humans. They are broad-spectrum surface-acting agents secreted by the epithelial cells of the body in response to infection. Recently, L-isoleucine and its analogues have been found to induce antimicrobial peptides. The objectives of the study were to examine if addition of L-isoleucine to oral rehydration salts (ORS) solution would reduce stool output and/or duration of acute diarrhoea in children and induce antimicrobial peptides in intestine. This double-blind randomized controlled trial was conducted at the Dhaka Hospital of ICDDR,B. Fifty male children, aged 6-36 months, with acute diarrhoea and some dehydration, attending the hospital, were included in the study. Twenty-five children received L-isoleucine (2 g/L)-added ORS (study), and 25 received ORS without L-isoleucine (control). Stool weight, ORS intake, and duration of diarrhoea were the primary outcomes. There was a trend in reduction in mean +/- standard deviation (SD) daily stool output (g) of children in the L-isoleucine group from day 2 but it was significant on day 3 (388 +/- 261 vs. 653 +/- 446; the difference between mean [95% confidence interval (CI) (-)265 (-509, -20); p = 0.035]. Although the cumulative stool output from day 1 to day 3 reduced by 26% in the isoleucine group, it was not significant. Also, there was a trend in reduction in the mean +/- SD intake of ORS solution (mL) in the L-isoleucine group but it was significant only on day 1 (410 +/- 169 vs. 564 +/- 301), the difference between mean (95% CI) (-)154 (-288, -18); p = 0.04. The duration (hours) of diarrhoea was similar in both the groups. A gradual increase in stool concentrations of beta-defensin 2 and 3 was noted but they were not significantly different between the groups. L-isoleucine-supplemented ORS might be beneficial in reducing stool output and ORS intake in children with acute watery diarrhoea. A further

    Safe domestic potable water supplies are urgently needed to reduce childhood diarrheal disease. In periurban neighborhoods in Cochabamba, Bolivia, we conducted a cluster randomized controlled trial to evaluate the efficacy of a household-level hollow fiber filter and/or behavior change communication (BCC) on water, sanitation, and hygiene (WASH) to reduce the diarrheal disease in children less than 5 years of age. In total, 952 households were followed for a period of 12 weeks post-distribution of the study interventions. Households using Sawyer PointONE filters had significantly less diarrheal disease compared with the control arm during the intervention period, which was shown by diarrheal prevalence ratios of 0.21 (95% confidence interval [95% CI] = 0.15-0.30) for the filter arm and 0.27 (95% CI = 0.22-0.34) for the filter and WASH BCC arm. A non-significant reduction in diarrhea prevalence was reported in the WASH BCC study arm households (0.71, 95% CI = 0.59-0.86).

    Described are the findings of a multicentre cohort study to test an algorithm for the treatment of persistent diarrhoea relying on the use of locally available, inexpensive foods, vitamin and mineral supplementation, and the selective use of antibiotics to treat associated infections. The initial diet (A) contained cereals, vegetable oil, and animal milk or yoghurt. The diet (B) offered when the patient did not improve with the initial regimen was lactose free, and the energy from cereals was partially replaced by simple sugars. A total of 460 children with persistent diarrhoea, aged 4-36 months, were enrolled at study centres in Bangladesh, India, Mexico, Pakistan, Peru, and Viet Nam. The study population was young (11.5 +/- 5.7 months) and malnourished (mean weight-for-age Z-score, -3.03 +/- 0.86), and severe associated conditions were common (45% required rehydration or treatment of severe infections on admission). The overall success rate of the treatment algorithm was 80% (95% CI, 76-84%). The recovery rate among all children with only diet A was 65% (95% CI, 61-70%), and was 71% (95% CI, 62-81%) for those evaluated after receiving diet B. The children at the greatest risk for treatment failure were those who had acute associated illnesses (including cholera, septicaemia, and urinary tract infections), required intravenous antibiotics, and had the highest initial purging rates. Our results indicate that the short-term treatment of persistent diarrhoea can be accomplished safely and effectively, in the majority of patients, using an algorithm relying primarily on locally available foods and simple clinical guidelines. This study should help establish rational and effective treatment for persistent diarrhoea. PMID:9002328

  4. Reducing disease burden and health inequalities arising from chronic disease among indigenous children: an early childhood caries intervention in Aotearoa/New Zealand

    PubMed Central

    2013-01-01

    Background Maaori are the Indigenous people of New Zealand and do not enjoy the same oral health status as the non-Indigenous majority. To overcome oral health disparities, the life course approach affords a valid foundation on which to develop a process that will contribute to the protection of the oral health of young infants. The key to this process is the support that could be provided to the parents or care givers of Maaori infants during the pregnancy of the mother and the early years of the child. This study seeks to determine whether implementing a kaupapa Maaori (Maaori philosophical viewpoint) in an early childhood caries (ECC) intervention reduces dental disease burden among Maaori children. The intervention consists of four approaches to prevent early childhood caries: dental care provided during pregnancy, fluoride varnish application to the teeth of children, motivational interviewing, and anticipatory guidance. Methods/design The participants are Maaori women who are expecting a child and who reside within the Maaori tribal area of Waikato-Tainui. This randomised-control trial will be undertaken utilising the principles of kaupapa Maaori research, which encompasses Maaori leadership, Maaori relationships, Maaori customary practices, etiquette and protocol. Participants will be monitored through clinical and self-reported information collected throughout the ECC intervention. Self-report information will be collected in a baseline questionnaire during pregnancy and when children are aged 24 and 36 months. Clinical oral health data will be collected during standardised examinations at ages 24 and 36 months by calibrated dental professionals. All participants receive the ECC intervention benefits, with the intervention delayed by 24 months for participants who are randomised to the control-delayed arm. Discussion The development and evaluation of oral health interventions may produce evidence that supports the application of the principles of kaupapa

    Epidemic surveillance is an effective means to determine the characteristics of acute diarrhoea and the benefits of disease control and prevention. The epidemiological, clinical, and aetiological data of adult (aged ⩾15 years) acute diarrhoea in a general hospital in Shanghai were collected and analysed. Out of 2430 acute diarrhoea patients, 162 subjects were sampled (sample ratio 15:1). The sampled subjects had an average age (±s.d.) of 44 ± 18 years; 142 (87·7%) had a history that indicated ingestion of contaminated food; and 40 (24·7%), 54 (33·3%), and 73 (45·1%) patients had diarrhoea that was attributed to viral, bacterial, and unknown aetiological origins respectively. Viral diarrhoea is mainly prevalent during the winter and spring months, while bacterial and diarrhoea of unknown aetiology occur mainly in the summer months. The average age of the unknown aetiology group (48 ± 19 years) was significantly older than that of the viral diarrhoea group (39 ± 16 years). The number of patients with vomiting in the viral group (30·6%) was significantly higher than that in the bacterial (17·1%) and unknown aetiology (8·2%) groups. Viral and bacterial infections are the main cause of acute diarrhoea in Shanghai. However, further effective technological means are needed to improve the surveillance, control, and prevention of acute diarrhoea.

    Background. Although diosmectite has demonstrated efficacy in the treatment of acute watery diarrhoea in children, its efficacy in adults still needs to be assessed. The objective of this study was therefore to assess the efficacy of diosmectite on the time to recovery in adults with acute diarrhoea. Methods. A total of 346 adults with at least three watery stools per day over a period of less than 48 hours were prospectively randomized to diosmectite (6 g tid) or placebo during four days. The primary endpoint was time to diarrhoea recovery. Results. In the intention-to-treat population, median time to recovery was 53.8 hours (range [3.7–167.3]) with diosmectite (n = 166) versus 69.0 hours [2.2–165.2] with placebo, (n = 163; P = .029), which corresponds to a difference of 15.2 hours. Diosmectite was well tolerated. Conclusion. Diosmectite at 6 g tid was well tolerated and reduced the time to recovery of acute watery diarrhoea episode in a clinically relevant manner.

  11. The effect of New Neonatal Porcine Diarrhoea Syndrome (NNPDS) on average daily gain and mortality in 4 Danish pig herds

    PubMed Central

    2014-01-01

    Background The study evaluated the effect of New Neonatal Porcine Diarrhoea Syndrome (NNPDS) on average daily gain (ADG) and mortality and described the clinical manifestations in four herds suffering from the syndrome. NNPDS is a diarrhoeic syndrome affecting piglets within the first week of life, which is not caused by enterotoxigenic Escherichia coli (ETEC), Clostridium perfringens (C. perfringens) type A/C, Clostridium difficile (C. difficile), rotavirus A, coronavirus, Cystoisospora suis, Strongyloides ransomi, Giardia spp or Cryptosporidium spp. Results Piglets were estimated to have a negative ADG of 9 and 14 g when diarrhoeic for 1 day and >1 day respectively. However, if only diarrhoeic on the day of birth, no negative effect on ADG was seen. Piglets originating from severely affected litters were estimated to have a reduced ADG of 38 g. The study did not show an overall effect of diarrhoea on mortality, but herd of origin, sow parity, birth weight, and gender were significantly associated with mortality. In one of the herds, approximately 25% of the diarrhoeic piglets vs. 6% of the non-diarrhoeic piglets died, and 74% of necropsied piglets were diagnosed with enteritis. These findings indicate that the high mortality seen in this herd was due to diarrhoea. Conclusions NNPDS negatively affected ADG in piglets, and even piglets that were diarrhoeic for one day only experienced a reduction in ADG. However, the study showed that diarrhoea restricted to the day of birth did not affect ADG and suggested this phenomenon to be unrelated to the syndrome. Since the diarrhoeal status of the litter had important effects on ADG, future research on NNPDS probably ought to focus on piglets from severely affected litters. The study showed important dissimilarities in the course of diarrhoea between the herds, and one herd was considerably more affected than the others. Within this herd, NNPDS seemed to be associated with a higher mortality, whereas in general the

  12. Trends in childhood disease.

    Child mortality has declined remarkably during the last decades. While neonatal disorders, diarrhoea, pneumonia, and malaria as well as being underweight account for most of the child deaths worldwide, children's health discussions in Europe and the USA focus on other issues such as asthma, neurodevelopmental disorders, male genital malformations, and childhood cancer. There is clear evidence of increasing rates of asthma in various countries during the last decades, although rates in some countries may now have stabilised or even decline as recent UK data indicate. Although an increase in the frequency of neurodevelopmental disorders such as autism and attention deficit disorder has frequently been discussed, the limited data in this field does not justify such a conclusion. While geographic heterogeneity regarding reproductive outcomes is apparent, global trends have not been identified. Interpretation of the available information on asthma, neurodevelopmental disorders and reproductive outcomes is hampered by inconstant diagnostic criteria over place and time and the lack of good and comprehensive population-based surveillance data, which makes it impossible to ascertain trends in actual disease frequency. Data indicate that developed countries have a gradually increasing incidence in leukaemia with a corresponding drop in the incidence of lymphoma. Increases in brain tumour frequency may be related to the development and wide application of new diagnostic capabilities, rather than a true change in the incidence of malignant disease. With a better prognosis for childhood cancer survival, secondary cancers following chemotherapy appear to be increasing. A wide range of environmental factors is thought to have an impact on children's health. These factors include nutrition (protein, vitamins, antioxidants), lifestyle and behaviour choices such as tobacco and alcohol use, parental health, socio-economic status, choice of living environment (urban versus rural, etc

    Diarrhoea is considered to be the second leading cause of death due to infections among children  < 5 years of age worldwide that may be caused by bacteria, parasites, viruses and non-infectious agents. The major causative agents of diarrhoea in developing countries may vary from those in developed countries. Noroviruses are considered to be the most common cause of acute diarrhoea in both children and adults in industrialized countries. On the other hand, there is a lack of comprehensive epidemiological evidence from developing countries that norovirus is a major cause of diarrhoea. In these regions, asymptomatic norovirus infections are very common, and similar detection rates have been observed in patients with diarrhoea and asymptomatic persons. This review summarizes the current knowledge of norovirus infection in developing countries and seeks to position infections with noroviruses among those of other enteropathogens in terms of disease burden in these regions.

    Infectious gastroenteritis continues to be a leading cause of mortality and morbidity worldwide. The cornerstone of treatment remains replacement of water and electrolyte losses with oral rehydration solution. Until a few years ago, probiotics were discussed primarily in the context of alternative medicine, but they are now entering mainstream medical practice since a decrease of the severity and duration of infectious gastroenteritis in approximately 24 hours has been shown for some strains. Therefore, probiotics are a potential add-on therapy in acute gastro-enteritis. The shortening of the duration of diarrhoea and the reduction in hospital stay result in a social and economic benefit. Evidence found in viral gastroenteritis is more convincing than in bacterial or parasitic infection. Mechanisms of action are strain specific and only those commercial products for which there is evidence of clinical efficacy should be recommended. Timing of administration is also of importance. In acute gastroenteritis, there is evidence for efficacy of some strains of lactobacilli (e.g. Lactobacillus caseii GG and Lactobacillus reuteri) and for Saccharomyces boulardii. Probiotics are "generally regarded as safe", but side effects such as septicaemia and fungaemia have very rarely been reported in high-risk situations. Although most studies conclude in a statistically significant shortening of the duration of diarrhea, the clinical relevance of this finding is limited. In conclusion, selected strains of probiotics result in a statistically significant but clinically moderate benefit in shortening the duration of diarrhoea caused by acute infectious gastroenteritis.

    Canine circovirus (CanineCV) has been detected in some dogs with severe haemorrhagic diarrhoea, but its pathogenic role is unclear. This study evaluated a suspected association between the presence of CanineCV and acute haemorrhagic diarrhoea syndrome (AHDS) in dogs. The prevalence of CanineCV in dogs with AHDS was compared with that in healthy dogs and those infected with canine parvovirus (CPV). Additionally, time to recovery and mortality rate were compared between CanineCV-positive and CanineCV-negative dogs. Faecal samples of dogs with AHDS (n=55), healthy dogs (n=66) and dogs infected with CPV (n=54) were examined by two real-time TaqMan PCR assays targeting the replicase and capsid genes of CanineCV. CanineCV was detected in faecal samples of two dogs with AHDS, three healthy controls and seven dogs infected with CPV. Among the three groups, there was no significant difference in prevalence of CanineCV. CPV-infected animals that were coinfected with CanineCV had a significantly higher mortality rate compared with those negative for CanineCV. CanineCV does not appear to be the primary causative agent of AHDS in dogs, but might play a role as a negative co-factor in disease outcome in dogs with CPV infection.

    The risk factors for childhood overweight and obesity are known and can be identified antenatally or during infancy, however, the majority of effective interventions are designed for older children. This review identified interventions designed to reduce the risk of overweight/obesity that were delivered antenatally or during the first 2 years of life, with outcomes reported from birth to 7 years of age. Six electronic databases were searched for papers reporting randomised controlled trials of interventions published from January 1990 to September 2013. A total of 35 eligible studies were identified, describing 27 unique trials of which 24 were behavioural and three were non-behavioural. The 24 behavioural trials were categorised by type of intervention: (1) nutritional and/or responsive feeding interventions targeted at parents of infants, which improved feeding practices and had some impact on child weight (n = 12); (2) breastfeeding promotion and lactation support for mothers, which had a positive effect on breastfeeding but not child weight (n = 5); (3) parenting and family lifestyle (n = 4); and (4) maternal health (n = 3) interventions that had some impact on feeding practices but not child weight. The non-behavioural trials comprised interventions manipulating formula milk composition (n = 3). Of these, lower/hydrolysed protein formula milk had a positive effect on weight outcomes. Interventions that aim to improve diet and parental responsiveness to infant cues showed most promise in terms of self-reported behavioural change. Despite the known risk factors, there were very few intervention studies for pregnant women that continue during infancy which should be a priority for future research.

    This population-based study was conducted to determine the prevalence, mortality, and socio-environmental determinants of diarrhoeal diseases in children less than 5-years of age in a rural area of Akoko North, Ondo State, Nigeria. A total of 856 households with children less than 5-years old were randomly selected for the questionnaire and observational investigations. A two-week prevalence rate of the diseases among the children was 8.1%. The rate was highest among children 0-11 months old and slightly higher among the boys than girls. The infant mortality rate was 102/1000 and the mortality rate in less than 5-year old children was 62.1/1000 in the area. The majority of these deaths took place in the homes and health centres and were never reported. Social and environmental factors including dirty feeding bottles and utensils, inadequate disposal of faeces and household refuse, and poor storage of drinking water were found to be significantly related to the high incidence of the diseases. Educational interventions recommended for the control of the disease focused on these factors.

  19. Impact of treatment planning target volumen (PTV) size on radiation induced diarrhoea following selenium supplementation in gynecologic radiation oncology - a subgroup analysis of a multicenter, phase III trial

    PubMed Central

    2013-01-01

    Background In a previous analysis (Int J Radiat Oncol Biol Phys 70:828-835,2010), we assessed whether an adjuvant supplementation with selenium (Se) improves Se status and reduces the radiation-induced side-effects of patients treated by adjuvant radiotherapy (RT) for cervical and uterine cancer. Now, a potential relation between the planning target volume (PTV) of the RT and the Se effect concerning radiation induced diarrhoea was evaluated in detail. Methods Whole blood Se concentrations had been measured in patients with cervical (n=11) and uterine cancer (n=70) after surgical treatment, during, and at the end of RT. Patients with initial Se concentrations of less than 84 μg/l were categorized as Se-deficient and randomized before RT to receive Se (as sodium selenite) per os on the days of RT, or to receive no supplement during RT. Diarrhoea was graded according to the Common Toxicity Criteria system (CTC, Version 2a). The evaluation of the PTV of the RT was ascertained with the help of a specialised computer-assisted treatment planning software used for radiation planning procedure. Results A total of 81 patients had been randomized for the initial supplementation study, 39 of which received Se [selenium group, SeG] and 42 serving as controls [control group, CG]. Mean Se levels did not differ between SeG and CG upon study initiation, but were significantly higher in the SeG compared to the CG at the end of RT. The actuarial incidence of at least CTC 2 radiation induced diarrhoea in the SeG was 20.5% compared to 44.5% in the CG (p=0.04). The median PTV in both groups was 1302 ml (916–4608). With a PTV of <= 1302 ml (n=41) the actuarial incidence of at least CTC 2 diarrhoea in the SeG was 22.3% (4 of 18 patients) compared to 34.8% (8 of 23 patients) in the CG (p=0.50). In patients with a PTV of > 1302 ml (n=40) the actuarial incidence of at least CTC 2 diarrhoea in the SeG was 19.1% (4 of 21 patients) versus 52.6% (10 of 19 patients) in the CG (p=0

    Chemotherapy-induced diarrhoea is a major oncological problem, caused by the cytotoxic effects of cancer chemotherapy. Irinotecan is linked with severe mucositis and diarrhoea, the mechanisms of which remain poorly understood. Bacterial β-glucuronidase is thought to be involved in the metabolism of irinotecan, implicating the intestinal flora. Intestinal mucins may also be implicated in the development of chemotherapy-induced diarrhoea. Rats were treated with 200 mg/kg of irinotecan and killed at 96, 120 and 144 h. The rats were monitored for diarrhoea. Pathology and immunohistochemical staining was performed. The samples were cultured and faecal DNA was analysed using real-time polymerase chain reaction. Severe diarrhoea was observed from 72 to 96 h. A decrease in body mass was also observed after treatment. Significant changes in goblet cell numbers (both complete and cavitated cells) were observed in the small and large intestines. Changes in MUC gene expression were observed in the small intestine only. Modifications were observed to the intestinal flora profile, especially Escherichia coli, and an increase in the expression of β-glucuronidase was detected. In conclusion, irinotecan-induced diarrhoea may be caused by an increase in some β-glucuronidase-producing bacteria, especially E. coli, exacerbating the toxicity of active metabolites. Accelerated mucous secretion and mucin release may also contribute to the delayed onset of diarrhoea. PMID:19765103

    Diarrhoeal management practices are unsatisfactory in India especially in the slum areas. Dearth of information regarding physicians' diarrhoea-related knowledge and practice in India necessitated this cross-sectional study of allopathic practitioners in the slums of Kolkata, to assess the distribution and interrelationship between physicians' characteristics, knowledge and practice regarding diarrhoea. A total of 264 randomly selected consenting practitioners were interviewed using a field-tested questionnaire. Nineteen percent had good overall knowledge, 49% and 80% prescribed antibiotics to diarrhoea and cholera patients, respectively, and 55% advised stool examination for every case. Qualified and Government physicians had better knowledge regarding diarrhoea [MBBS: odds ratio (OR) 5·96, P < 0·001; postgraduates: OR 9·33, P < 0·001; Government physicians: OR 11·49, P < 0·0001] and were less likely to prescribe antibiotics for all diarrhoea cases (MBBS: OR 0·30, P = 0·002; postgraduates: OR 0·20, P < 0·001; Government physicians OR 0·24, P < 0·029). Better knowledge was associated with a lower likelihood of prescribing antibiotics for diarrhoea (OR 0·72, P < 0·001), cholera (OR 0·78, P = 0·027) and investigative procedure (OR 0·85, P = 0·028). In the slums of Kolkata, diarrhoea-related knowledge and practice were poor with the exception of qualified physicians, hence an improvement in the knowledge of pharmacists and unqualified practitioners is necessary for the overall improvement of diarrhoeal management in these slums.

    This study aims to determine the predictors of acute diarrhoea among hospitalized children in the Gaza Governorates. The case-control design included 140 children (70 cases and 70 controls) in a stratified cluster sample from Naser Medical Complex and Alnasser Pediatric Hospital. An interview questionnaire was used, and face and content validations were performed. Multiple logistic regression was used for the multivariate analysis of risk factors of diarrhoea in children aged less than five years. Results showed a significant association between diarrhoea and family income, residence, complementary feeding, and age of weaning (p<0.05). Children living in villages had lower odds of having diarrhoea by 53.2% than children living in cities. Children of families with incomes between US$ 485 and 620 had lower odds of having diarrhoea by 80.8% than children of families with incomes less than US$ 485. Moreover, children who did not receive complementary feeding had lower odds of having diarrhoea by 59.0%. We found that, for one month increase in weaning age, the odds of diarrhoea decreased by 1.06 times (adjusted OR=1.05, 95% CI 1.0180-1.100). The study concludes that urban residence, lower family income, complementary feeding, and lower age of weaning are risk factors of diarrhoea among children aged less than five years in the Gaza Strip. The results of the study suggest that children of low-income families and those who were not naturally breastfed may warrant more attention for prevention and/or treatment of diarrhoea.

    The genetic characteristics, of 38 field isolates of bovine viral diarrhoea virus (BVDV) collected in 1999 from sick or healthy and persistently infected cattle of dairy farms situated in northern Italy, were investigated. A partial 5'-untranslated region (5'-UTR) sequence of each isolate was determined and a phylogenetic analysis was performed. All the isolates were classified as belonging to the BVDV-1 genotype and could be assigned to different BVDV-1 groups, namely BVDV-1b (n = 20), BVDV-1d (n = 6) and BVDV-1e (n = 10). Two remaining isolates could be classified as BVDV-1f and BVDV-1h, respectively. These results provided evidence for genetic heterogeneity of BVDV in Italy, and contribute to a better knowledge of the circulation of BVDV strains, and to their classification.

    Hela S3 cells were grown in suspension both randomly and, synchronously using hydroxyurea which blocks cells at the G1/S interface. Cryosections were prepared, freeze-dried and analyzed by X-ray microanalysis. As cells moved into S and through M phases (Na) and (Cl) increased; both returned to normal levels upon re-entering G1 phase. The Na/K ratio was 1:1 in G1 phase. Infection of HeLa S3 cells in G1 phase with vaccinia virus resulted in no change in intracellular (Na). Infection of neonatal mice with murine rotavirus was localized to villus tip enterocytes and gave rise to diarrhoea which was maximal at 72h post-infection (p.i.). Diarrhoea was preceded by ischemia of villi (18-42h p.i.) and villus shortening (maximal at 42h p.i.), and was also coincident with a dramatic regrowth of villi. At 48h p.i. a proliferative zone of electron lucent cells was observed in villus base regions. Cryosections of infected gut, taken before, during, and after infection, together with corresponding age-matched controls, were freeze-dried and analysed by X-ray microanalysis. At 48h p.i. electron lucent villus base cells were shown to be more hydrated, and, to contain higher levels of both Na and Cl and lower levels of P, S, K and Mg than corresponding control cells. These studies increase confidence in the use of X-ray microanalysis in studying biological systems, provide some insight into the process of cell division, and constitute the basis of a new concept of diarrhoeal secretion.27 references.

    Symptomatic cytomegalovirus (CMV) infection mainly affects preterm and immunocompromised infants and usually manifest as rash, pneumonia, hepatospleenomegaly or encephalitis. To our knowledge intractable diarrhoea at two weeks of age caused by postnatally acquired CMV in immunocompetent term neonate is not reported. An unusual case of postnatally acquired CMV enterocolitis manifesting as protracted diarrhoea in an immunocompetent baby in neonatal period is reported. We conclude that CMV should be considered in the differential diagnosis of intractable diarrhoea in neonatal period and treatment with intravenous ganciclovir for CMV enterocolitis is not only indicated but is therapeutic.

    Clinical summary Childhood obesity has important consequences for health and wellbeing both during childhood and also in later adult life. The rising prevalence of childhood obesity poses a major public health challenge in both developed and developing countries by increasing the burden of chronic non-communicable diseases. Despite the urgent need for effective preventative strategies, there remains disagreement over its definition due to a lack of evidence on the optimal cut-offs linking childhood BMI to disease risks, and limited evidence on the most effective components of interventions to prevent childhood obesity. This article reviews the trends in childhood obesity, its genetic, nutritional and other risk factors, and preventative and treatment strategies. Particular emphasis is given to early-onset obesity in pre-school children, which, as a precursor to later childhood and adult obesity, provides insights into the developmental and genetic origins of obesity and also offers the potential for early preventative approaches with long-lasting benefits.

    Childhood TB is an indication of failing TB control in the community. It allows disease persistence in the population. Mortality and morbidity due to TB is high in children. Moreover, HIV co-infection and multidrug-resistant diseases are as frequent in children as in adults. Infection is more frequent in younger children. Disease risk after primary infection is greatest in infants younger than 2 years. In case of exposure, evidence of infection can be obtained using the tuberculin skin test (TST) or an interferon-gamma assay (IGRA). There is no evidence to support the use of IGRA over TST in young children. TB suspicion should be confirmed whenever possible, using new available tools, particularly in case of pulmonary and lymph node TB. Induced sputum, nasopharyngeal aspiration and fine needle aspiration biopsy provide a rapid and definitive diagnosis of mycobacterial infection in a large proportion of patients. Analysis of paediatric samples revealed higher sensitivity and specificity values of molecular techniques in comparison with the ones originated from adults. Children require higher drugs dosages than adults. Short courses of steroids are associated with TB treatment in case of respiratory distress, bronchoscopic desobstruction is proposed for severe airways involvement and antiretroviral therapy is mandatory in case of HIV infection. Post-exposure prophylaxis in children is a highly effective strategy to reduce the risk of TB disease. The optimal therapy for treatment of latent infection with a presumably multidrug-resistant Mycobacterium tuberculosis strain is currently not known.

    Many recent studies have demonstrated that routine examination of faeces for conventional enteric pathogens such as salmonella, shigella, campylobacter and parasites in patients who develop sporadic hospital-acquired diarrhoea is unnecessary and wasteful. In this paper the advantages and disadvantages of a restricted testing protocol in patients with hospital-acquired diarrhoea are reviewed. Practical issues for safe implementation of such a protocol are also discussed.

    The Mekong Delta is vulnerable to changes in climate and hydrological events which alter environmental conditions, resulting in increased risk of waterborne diseases. Research exploring the association between climate factors and diarrhoea, the most frequent waterborne disease in Mekong Delta region, is sparse. This study evaluated the climate-diarrhoea association in Can Tho city, a typical Mekong Delta area in Vietnam. Climate data (temperature, relative humidity, and rainfall) were obtained from the Southern Regional Hydro-Meteorological Centre, and weekly counts of diarrhoea visits were obtained from Can Tho Preventive Medicine Centre from 2004 to 2011. Analysis of climate and health variables was carried out using spline function to adjust for seasonal and long-term trends of variables. A distributed lag model was used to investigate possible delayed effects of climate variables on diarrhoea (considering 0-4 week lag periods), then the multivariate Poisson regression was used to examine any potential association between climate factors and diarrhoea. The results indicated that the diarrhoea incidence peaked within the period August-October annually. Significant positive associations were found between increased diarrhoea and high temperature at 4 weeks prior to the date of hospital visits (IRR = 1.07; 95 % CI = 1.04-1.08), high relative humidity (IRR = 1.13; 95 % CI = 1.12-1.15) and high (>90th percentile) cumulative rainfall (IRR = 1.05; 95 % CI = 1.05-1.08). The association between climate factors and diarrhoea was stronger in rural than urban areas. These findings in the context of the projected changes of climate conditions suggest that climate change will have important implications for residential health in Mekong Delta region.

    Diarrhoea is a common cause of death in children and weaned animals. Recent research has found that serotonin (5-HT) in the gastrointestinal tract plays an important role in regulating growth and the maintenance of mucosa, which protect against diarrhoea. To determine the influence of 5-HT on intestinal epithelium cell renewal under weaned stress diarrhoea, a weaned-stress diarrhoea mouse model was established with senna infusion (15 mL/Kg) via intragastric administration and stress restraint (SR). Mice with an increase in 5-HT were induced by intraperitoneal injection with citalopram hydrobromide (CH, 10 mg/Kg). The results demonstrated that compared with the control animals, diarrhoea appeared in weaned stress mice and the 5-HT content in the small intestine was significantly increased (P<0.05). Further, the caspase-3 cells and cells undergoing apoptosis in the small intestine were significantly increased, but the VH (villus height), V/C (villus height /crypt depth), and PCNA-positive rate significantly decreased. Compared with the control animals, CH increased the intestinal 5-HT content, caspase-3 cells and cells undergoing apoptosis but decreased the VH and V/C. Compared with both control and weaned stress animals, weaned stress animals that were pre-treated with CH showed higher 5-HT concentrations, positive caspase-3 cells and cells undergoing apoptosis but lower VH, V/C and PCNA-positive rate. In vitro, a low concentration of 5-HT inhibit, IEC-6 cell line apoptosis but a higher concentration of 5-HT promoted it. Therefore, weaned stress diarrhoea mice were accompanied by a 5-HT increase in the small intestine and vice versa, and the increase in 5-HT induced by CH caused diarrhoea. In brief, 5-HT and diarrhoea slowed the intestinal epithelium cell renewal and injured the abortion function and mucosal barrier by decreasing VH, V/C and proliferation and increasing epithelium cell apoptosis.

    Nine flocks of sheep with a high prevalence (>30%) of diarrhoea and severe breech faecal soiling were investigated over a three-year period to examine the causes of diarrhoea in sheep with low mean faecal worm egg counts (WEC). All nine flocks were located in the southwest of Western Australia in areas with a winter rainfall pattern (Mediterranean climate). There was no difference (p=0.304) in WEC of diarrhoeic sheep (loose faeces and severe breech faecal soiling) and "normal sheep" (pelleted faeces and mild or no breech faecal soiling). Teladorsagia (Ostertagia) circumcincta and Trichostrongylus spp. were the nematodes most commonly identified by total worm counts and differentiation of larvae recovered from faeces and pasture. Larval stages of strongyle worms accounted for the largest proportion of total worm counts in both diarrhoeic and normal sheep. Adult worm burdens were small in most sheep. Diarrhoeic sheep had higher numbers of fourth stage larvae than normal sheep (p=0.046). There was no histopathological evidence of bacterial or viral causes of diarrhoea in any of the flocks or bacteriological evidence of bacterial infections associated with diarrhoea. Two flocks had marginal selenium glutathione peroxidase (selenium) levels. One flock was diagnosed with helminthosis based on rising WEC and high total worm counts. Larval hypersensitivity diarrhoea, nutritional factors or a combination of these two factors were the most likely causes of diarrhoea in the other eight flocks based on exclusion of other known causes of diarrhoea. Treatment with moxidectin and an ivermectin controlled-release capsule did not change faecal moisture content of treated sheep compared to untreated sheep three to five weeks after treatment. The findings suggest that the immune response to strongyle larvae may explain some cases of low WEC diarrhoea observed during winter-spring in immunocompetent mature sheep grazing in Mediterranean environments.

    The aim of this study was to compare the cumulative incidence of mortality, clinical diarrhoea and respiratory disease in calves, during their first six months of age, in herds with different bovine viral diarrhoea virus (BVDV) infection status. Calves' health indicators were tested by comparing proportions in 101 farms with dissimilar infection condition. The results indicate that there was a significant relationship between the BVDV status (actively infected herd or not) and the cumulative incidence of mortality and respiratory disorders.

    Diarrhoea occurs frequently in neutropenic patients with acute leukaemia receiving chemotherapy and may be caused by either infection- or drug-induced cytotoxicity. Since Clostridium difficile is the most common cause of nosocomial infectious diarrhoea in non-haematologic patients, we were interested in its incidence in patients with acute myeloid leukaemia (AML). In this retrospective study, we analysed 134 patients with AML receiving a total of 301 chemotherapy courses. Diarrhoea occurred during 33% of all courses in 58 patients. C. difficile-associated diarrhoea (CDAD) occurred in 18% of all patients and 9% of all treatment courses. Almost one third of diarrhoea episodes were caused by C. difficile. CDAD was associated with older age (58 vs. 50 years), number of antibiotics administered (2 vs. 1), duration of antibiotic therapy (7 vs. 4 days), ceftazidime as the antibiotic of choice (75% vs. 54%) and duration of neutropenia (12 vs. 7 days) prior to onset of diarrhoea. An increased risk for CDAD was seen for prolonged neutropenia. CDAD responded well to oral metronidazole and/or vancomycin and no patient died of this complication. In conclusion, CDAD is common in patients with AML receiving chemotherapy. C. difficile enterotoxin testing of stool specimens should be included in all symptomatic patients.

    This paper identifies groups vulnerable to the effect of flooding on hospital visits due to diarrhoea during and after a flood event in 1998 in Dhaka, Bangladesh. The number of observed cases of cholera and non-cholera diarrhoea per week was compared to expected normal numbers during the flood and post-flood periods, obtained as the season-specific average over the two preceding and subsequent years using Poisson generalised linear models. The expected number of diarrhoea cases was estimated in separate models for each category of potential modifying factors: sex, age, socio-economic status and hygiene and sanitation practices. During the flood, the number of cholera and non-cholera diarrhoea cases was almost six and two times higher than expected, respectively. In the post-flood period, the risk of non-cholera diarrhoea was significantly higher for those with lower educational level, living in a household with a nonconcrete roof, drinking tube-well water (vs. tap water), using a distant water source and unsanitary toilets. The risk for cholera was significantly higher for those drinking tube-well water and those using unsanitary toilets. This study confirms that low socio-economic groups and poor hygiene and sanitation groups were most vulnerable to flood-related diarrhoea.

    The compound 5-fluorouracil (5-FU) is used in cancer chemotherapy and is known to cause diarrhoea. We recently reported that chemokine (C-X-C motif) ligand 1 (CXCL1) and neutrophils in the colonic mucosa were markedly increased by the administration of 5-FU in mice. Curcumin has anti-inflammatory, antitumour and antioxidant properties. Therefore, we examined the effect of curcumin on 5-FU-induced diarrhoea development and CXCL1 and CXCL2 up-regulation in the colon. Mice were given 5-FU (50 mg/kg, i.p.) daily for 4 days. Curcumin (100 or 300 mg/kg, p.o.) was administered on the day before the first administration of 5-FU and administered 30 min. before the administration of 5-FU. Gene expression levels of CXCL1 and CXCL2 in the colon were examined by real-time RT-PCR. Curcumin reduced the 5-FU-induced diarrhoea development. Under this condition, the CXCL1 and CXCL2 gene up-regulated by 5-FU administration was inhibited by curcumin. The gene expression of CXCL1 and CXCL2 was also enhanced by 5-FU application in vitro. The 5-FU-induced up-regulated CXCL1 and CXCL2 gene expressions were inhibited by curcumin, Bay-117082 and bortezomib, nuclear factor kappa B (NF-κB) inhibitors, C646, a p300/cyclic adenosine monophosphate response element-binding protein-histone acetyltransferase (HAT) inhibitor. In conclusion, these findings suggested that curcumin prevented the development of diarrhoea by inhibiting NF-κB and HAT activation.

  20. Efficacy and mode of action of mesalazine in the treatment of diarrhoea-predominant irritable bowel syndrome (IBS-D): study protocol for a randomised controlled trial

    PubMed Central

    2013-01-01

    Background Irritable bowel syndrome (IBS) is reported by one in ten of the population accounting for up to 40% of new referrals to gastroenterology outpatients. Patients characteristically have abdominal discomfort and disturbed bowel habit. Diarrhoea-predominant IBS is characterised by frequent loose stools with associated urgency and abdominal cramps. Current symptomatic treatments can reduce bowel frequency but often fail to reduce discomfort. Mesalazine is an anti-inflammatory drug used to treat patients with inflammatory bowel disease. There is one pilot study suggesting it may be beneficial to patients who have diarrhoea-predominant IBS but these findings need to be confirmed in a larger trial. The current study aims to test the effectiveness of mesalazine to reduce symptoms in diarrhoea-predominant IBS patients. The study will also investigate the mode of action of the drug, especially its impact on mast cell activation. Methods/design This is a multicentre randomised, double-blind, placebo-controlled trial using a parallel group design. At least 108 participants with diarrhoea-predominant IBS will be recruited through at least six hospitals. The intervention is a 12-week course of 2g mesalazine granules taken up to twice a day. The comparator is a blinded placebo granule formulation. Outcome measures include stool diaries, symptom questionnaires, stool and blood samples together with rectal mucosal biopsies. The daily stool diary will record stool frequency and form, urgency, bloating, abdominal pain and a global satisfaction with control of IBS scored each week. The questionnaires will assess bowel symptoms, while the samples and biopsies will be used to analyse underlying mechanisms of any response. Primary outcome will be the average stool frequency during weeks 11 and 12 of the treatment period and will be compared between treatment arms using an analysis of covariance in the form of a general linear model incorporating baseline characteristics that are

    Summary Background Dehydration due to diarrhoea is a leading cause of child death worldwide, yet no clinical tools for assessing dehydration have been validated in resource-limited settings. The Dehydration: Assessing Kids Accurately (DHAKA) score was derived for assessing dehydration in children with diarrhoea in a low-income country setting. In this study, we aimed to externally validate the DHAKA score in a new population of children and compare its accuracy and reliability to the current Integrated Management of Childhood Illness (IMCI) algorithm. Methods DHAKA was a prospective cohort study done in children younger than 60 months presenting to the International Centre for Diarrhoeal Disease Research, Bangladesh, with acute diarrhoea (defined by WHO as three or more loose stools per day for less than 14 days). Local nurses assessed children and classified their dehydration status using both the DHAKA score and the IMCI algorithm. Serial weights were obtained and dehydration status was established by percentage weight change with rehydration. We did regression analyses to validate the DHAKA score and compared the accuracy and reliability of the DHAKA score and IMCI algorithm with receiver operator characteristic (ROC) curves and the weighted κ statistic. This study was registered with ClinicalTrials.gov, number NCT02007733. Findings Between March 22, 2015, and May 15, 2015, 496 patients were included in our primary analyses. On the basis of our criterion standard, 242 (49%) of 496 children had no dehydration, 184 (37%) of 496 had some dehydration, and 70 (14%) of 496 had severe dehydration. In multivariable regression analyses, each 1-point increase in the DHAKA score predicted an increase of 0·6% in the percentage dehydration of the child and increased the odds of both some and severe dehydration by a factor of 1·4. Both the accuracy and reliability of the DHAKA score were significantly greater than those of the IMCI algorithm. Interpretation The DHAKA score

    Investment in the promotion of better hygiene for the prevention of diarrhoeal diseases and as a component of water and sanitation programmes is increasing. Before designing programmes capable of sustainably modifying hygiene behaviour in large populations, valid answers to a number of basic questions concerning the site and the intended beneficiaries have to be obtained. Such questions include 'what practices favour the transmission of enteric pathogens?', 'what advantages will be perceived by those who adopt safe practices?' and 'what channels of communication are currently employed by the target population?' A study of hygiene and diarrhoea in Bobo-Dioulasso, Burkina Faso, used a mixture of methods to address such questions. This paper draws on that experience to propose a plan of preliminary research using a variety of techniques which could be implemented over a period of a few months by planners of hygiene promotion programmes. The techniques discussed include structured observation, focus group discussions and behavioural trials. Modest investment in such systematic formative research with clear and limited goals is likely to be repaid many times over in the increased effectiveness of hygiene promotion programmes.

    Background The burden of shigellosis is greatest in resource-poor countries. Although this diarrheal disease has been thought to cause considerable morbidity and mortality in excess of 1,000,000 deaths globally per year, little recent data are available to guide intervention strategies in Asia. We conducted a prospective, population-based study in six Asian countries to gain a better understanding of the current disease burden, clinical manifestations, and microbiology of shigellosis in Asia. Methods and Findings Over 600,000 persons of all ages residing in Bangladesh, China, Pakistan, Indonesia, Vietnam, and Thailand were included in the surveillance. Shigella was isolated from 2,927 (5%) of 56,958 diarrhoea episodes detected between 2000 and 2004. The overall incidence of treated shigellosis was 2.1 episodes per 1,000 residents per year in all ages and 13.2/1,000/y in children under 60 months old. Shigellosis incidence increased after age 40 years. S. flexneri was the most frequently isolated Shigella species (1,976/2,927 [68%]) in all sites except in Thailand, where S. sonnei was most frequently detected (124/146 [85%]). S. flexneri serotypes were highly heterogeneous in their distribution from site to site, and even from year to year. PCR detected ipaH, the gene encoding invasion plasmid antigen H in 33% of a sample of culture-negative stool specimens. The majority of S. flexneri isolates in each site were resistant to amoxicillin and cotrimoxazole. Ciprofloxacin-resistant S. flexneri isolates were identified in China (18/305 [6%]), Pakistan (8/242 [3%]), and Vietnam (5/282 [2%]). Conclusions Shigella appears to be more ubiquitous in Asian impoverished populations than previously thought, and antibiotic-resistant strains of different species and serotypes have emerged. Focusing on prevention of shigellosis could exert an immediate benefit first by substantially reducing the overall diarrhoea burden in the region and second by preventing the spread of

    A survey of acute diarrhoea and its treatment, in 3 groups of villages in south India, revealed that use of the World Health Organization oral rehydration solution (WHO-ORS) was poor or virtually non-existent and that several liquid foods were given to children during acute diarrhoea. The effects of the most commonly used, boiled and cooled supernatants of these liquid foods [rice (Oryza sativa)-water, ragi (Eleusine coracana)-water, arrowroot (Maranta arundinacea)-water], and tender coconut-water, and of the bicarbonate- and citrate-WHO-ORS on intestinal water transport were evaluated using a rat model of secretory diarrhoea. All solutions either decreased cholera toxin-induced net water secretion (arrowroot-water) or reversed it to net absorption. Ragi-water produced maximum net water absorption, significantly greater than the WHO oral rehydration solutions. WHO-ORS utilization is poor in some developing countries, and locally used food-based solutions could be used for maintaining hydration or correcting the dehydration due to acute diarrhoea once their effectiveness has been proved by clinical trials.

    This paper summarises the views of a European group of scientists involved in the control of bovine viral diarrhoea virus (BVDV), as part of a European Union Thematic Network. The group concludes that the technical tools and the knowledge needed to eradicate BVDV are at hand, as proven by successful national control schemes in several European countries. A generic model for BVDV control is presented, which includes biosecurity, elimination of persistently infected animals and surveillance as central elements. These elements are termed 'systematic', in contrast to control efforts without clear goals and surveillance to evaluate progress. The network concludes that a systematic approach is needed to reach a sustainable reduction in the incidence and prevalence of BVDV in Europe. The role of vaccines in systematic control programmes is considered as an additional biosecurity measure, the effect of which should be evaluated against cost, safety and efficacy. It is also concluded that active participation by farmers' organisations is a strong facilitator in the process that leads up to the initiation of control, and that public funding to support the initiation of organised BVD control programmes can be justified on the basis of expected wider societal benefits, such as animal welfare and reduction in the use of antibiotics. If applied successfully, the focus on biosecurity in systematic BVD control programmes would also reduce the risk of the introduction and spread of other epizootic and zoonotic agents, thereby improving both cattle health and welfare in general, as well as increasing the competitiveness of the cattle industry.

    The objective of this paper is to present a preliminary assessment of variation in the economic impact of bovine viral diarrhoea virus (BVDV) at dairy farm level between a sample of nations within the EU and hence assess differences in pressure to respond to this disease that may be impeding progress in control and hence restricting collective benefits from healthier livestock. We used a questionnaire to obtain national average values of key epidemiological and economic parameters for a typical dairy farm from BVDV experts in the countries concerned. These parameters were converted into assessments of economic impact using a computer simulation model. Uncontrolled output losses for a BVDV-naïve herd with virus introduced in year 1 of a 10-year epidemic represented 22, 7, 8, 5, 8 and 20% of the BVDV-free annuity for the UK, Northern Portugal, Holland, Norway, Italy and Germany, respectively. Differences between countries will be widened by differences in the risk of acquiring BVDV. These will be much reduced in countries, such as Norway that have a national BVDV eradication programme. Farmers in such countries can therefore justify spending much less on maintaining BVDV-free status than BVDV-free farms in other countries. This result illustrates the paradox that in countries where BVDV prevalence is high, farmers have least to gain from unilateral BVDV eradication because of the high cost of maintaining freedom from the disease. We discuss this issue in the light of increasing recognition at international level of the importance of BVDV control.

    2014-01-01

    The revised guideline on 'Acute diarrhoea' from the Dutch College of General Practitioners covers the diagnosis and management of suspected acute infectious diarrhoea. Acute diarrhoea resulting from infectious gastroenteritis is often caused by a virus and is usually self-limiting; stool testing is rarely indicated. The main complication of acute diarrhoea is dehydration, although this is rare in the Netherlands. Children under 2 years old and patients over 70 are at an increased risk of dehydration. Dehydration is a clinical diagnosis based on a combination of patient history and physical examination. DNA diagnostic methods such as polymerase chain reaction (PCR) are now available for stool testing, in addition to stool culture and the triple faeces test (TFT). PCR is preferred for its better test properties. Treatment with oral rehydration salts (ORS) is indicated for patients with dehydration and may also be useful in patients at an increased risk of this event. Acute diarrhoea after hospitalisation or after visiting the tropics or subtropics merits special attention on account of the risk of infection with unusual pathogens and the consequences with regard to management.

    Background Most diarrhoeal deaths can be prevented through the prevention and treatment of dehydration. Oral rehydration solution (ORS) and recommended home fluids (RHFs) have been recommended since 1970s and 1980s to prevent and treat diarrhoeal dehydration. We sought to estimate the effects of these interventions on diarrhoea mortality in children aged <5 years. Methods We conducted a systematic review to identify studies evaluating the efficacy and effectiveness of ORS and RHFs and abstracted study characteristics and outcome measures into standardized tables. We categorized the evidence by intervention and outcome, conducted meta-analyses for all outcomes with two or more data points and graded the quality of the evidence supporting each outcome. The CHERG Rules for Evidence Review were used to estimate the effectiveness of ORS and RHFs against diarrhoea mortality. Results We identified 205 papers for abstraction, of which 157 were included in the meta-analyses of ORS outcomes and 12 were included in the meta-analyses of RHF outcomes. We estimated that ORS may prevent 93% of diarrhoea deaths. Conclusions ORS is effective against diarrhoea mortality in home, community and facility settings; however, there is insufficient evidence to estimate the effectiveness of RHFs against diarrhoea mortality.

    A case-control study, aimed at identifying factors associated with rotavirus diarrhoea cases presenting to health facilities, was conducted in children from low-income and middle-low-income families in Brazil. Cases were 390 children with diarrhoea and rotavirus in stools; controls were 1674 children without diarrhoea presenting to the same facilities. Data were collected by questionnaire and observations during home visits. Explanatory variables were grouped according to a conceptual model of causation. The ORs by non-conditional logistic regression and population-attributable fractions were calculated. Socioeconomic factors contributed a third of cases, followed by contact with diarrhoea cases and by not being breast fed. In cases aged <1 year, not being breast fed was the main determinant, followed by socioeconomic factors, and crowding and contact outside the home; in older children, socioeconomic factors followed by contact inside and outside the home were the main determinants. Environmental and sanitation variables were not associated with diarrhoea in the final model, and socioeconomic factors were only partly mediated by proximal variables. Transmission of rotavirus appears to be mostly by person-to-person contact, and shows marked social differentials not explained by the biological factors studied. The rotavirus vaccine is unlikely to protect against the full range of circulating genotypes of rotavirus, and understanding rotavirus epidemiology remains essential to the development of control policies.

    In this hospital based study, Campylobacter jejuni, although endemic in Northern Thailand was not found in a significantly higher percentage of diarrhoea than in control children. It was isolated from the stools of 14 of 208 diarrhoea (6.7%) and 6 of 108 (5.5%) control patients. Ten of the 14 positive diarrhoea cases were mixed infections, other pathogens isolated simultaneously were enteropathogenic E. coli 4x, Shigella spp. 3x, Salmonella spp. 4x, rotavirus 3x, Plesiomonas shigelloides 1x and parasites 3x. Infection with Campylobacter jejuni occurred mainly in the 1-2 year age group and was not found in patients over 5. It was distributed over the year without seasonal peaks. In four of the 14 positive C. jejuni cases no other pathogens were found. One of these suffered 2nd degree malnutrition with measles and one was a chronic diarrhoea case with a history of antibiotic use and past Salmonella and Shigella infections. The remaining two cases had no underlying or associated illnesses. It was concluded that Campylobacter jejuni may be important as an associated pathogen in complicated diarrhoea infections but is rare as a sole causative agent.

    To estimate the proportion of cases missed in a passive surveillance study of diarrhoea and dysentery at health centres and hospitals in Kaengkhoi district, Saraburi province, Thailand, a community-based cluster survey of treatment-seeking behaviours was conducted during 21-23 June 2002. Interviews were conducted at 224 households among a study population of 78,744. The respondents reported where they sought care for diarrhoea and dysentery in children aged less than five years and adults aged over 15 years. Health centres or hospitals were the first treatment choice for 78% of children with dysentery (95% confidence interval [CI] 63-94%), 64% of children with diarrhoea (95% CI 54-74%), 61% of adults with dysentery (95% CI 40-82%), and 35% of adults with diarrhoea (95% CI 17-54%). A high degree of heterogeneity in responses resulted in a relatively large design effect (D=3.9) and poor intra-cluster correlation (rho=0.3). The community survey suggests that passive surveillance estimates of disease incidence will need to be interpreted with caution, since this method will miss nearly a quarter of dysentery cases in children and nearly two-thirds of diarrhoea cases in adults.

    Saccharomyces boulardii has been successfully used in the prevention and treatment of antimicrobial-associated diarrhoea in humans. We hypothesised that a viable, dried lyophilised preparation of S boulardii would survive in the gastrointestinal tract of horses with antimicrobial-associated enterocolitis, and significantly decrease the duration of diarrhoea. Twenty-one horses, over one year of age, with antimicrobial-associated diarrhoea of up to 72 hours duration, were consecutively randomised in a controlled prospective study. The treatment group received S boulardii (25 g, orally, every 12 hours) until the cessation of clinical signs. S boulardii was successfully cultured in 58.3 per cent of treatment horses on day 3. No statistically significant differences were found in days to return to normal faecal consistency; resolution of watery diarrhoea; return to normal heart rate, respiratory rate and temperature; resolution of leucopaenia; attitude improvement; appetite improvement; and survival at discharge. This is the first study to demonstrate survival of S boulardii in horses with gastrointestinal illness. Further study of the efficacy and safety of S boulardii in horses with antimicrobial-associated diarrhoea in a larger group is warranted.

    Background Trichohepatoenteric syndrome (THES) is an autosomal recessive disorder characterised by life-threatening diarrhoea in infancy, immunodeficiency, liver disease, trichorrhexis nodosa, facial dysmorphism, hypopigmentation and cardiac defects. We attempted to characterise the phenotype and elucidate the molecular basis of THES. Methods Twelve patients with classical THES from 11 families had detailed phenotyping. Autozygosity mapping was undertaken in 8 patients from consanguineous families using 250k single nucleotide polymorphism (SNP) arrays and linked regions evaluated using microsatellite markers. Linkage was confirmed to one region from which candidate genes were analysed. The effect of mutations on protein production and/or localisation in hepatocytes and intestinal epithelial cells from affected patients was characterised by immunohistochemistry. Results Previously unrecognised platelet abnormalities (reduced platelet α-granules, unusual stimulated alpha granule content release, abnormal lipid inclusions, abnormal platelet canalicular system and reduced number of microtubules) were identified. The THES locus was mapped to 5q14.3 – 5q21.2. Sequencing of candidate genes demonstrated mutations in TTC37, which encodes the uncharacterised tetratricopeptide repeat protein, thespin. Bioinformatic analysis suggested thespin to be involved in protein-protein interactions or chaperone. Preliminary studies of enterocyte brush-border ion transporter proteins (NHE2, NHE3, Aquaporin 7, Na/I symporter and H / K ATPase) showed reduced expression or mislocalisation in all THES patients with different profiles for each. In contrast the basolateral localisation of Na/K ATPase was not altered. Conclusion THES is caused by mutations in TTC37. TTC37 mutations have a multisystem effect which may be due to abnormal stability and / or intracellular localisation of TTC37 target proteins. PMID:20176027

    This study examines the efficiency of EPI cluster sampling in assessing the prevalence of diarrhoea and dysentery. A computer was used to simulate fieldwork carried out by a survey taker. The bias and variance of prevalence estimates obtained using EPI cluster sampling were compared with those obtained using simple random sampling and cluster (stratified random) sampling. Efficiency ratios, calculated as the mean square error divided by total distance travelled, were used to compare EPI cluster sampling to simple random sampling and standard cluster sampling. EPI cluster sampling may be an appropriate low-cost tool for monitoring trends in the prevalence of diarrhoea and dysentery over time. However, it should be used with caution when estimating the prevalence of diarrhoea at a single point in time because of the bias associated with this cluster sampling method. PMID:9447775

    A cross-sectional hospital-based study was carried out at Tikrit teaching hospital, Iraq, from October 2004 to September 2005, to identify the prevalence and etiology of nosocomial infectious diarrhoea among children under 5 years of age. Of 259 children admitted to the paediatric ward for reasons other than diarrhoea and hospitalized for more than 3 days, clinical and laboratory analysis of stool samples showed nosocomial diarrhoea in 84 children (32.4%). The most common causative agents were enteropathogenic Escherichia coli (25.9%), Clostridium difficile (21.0%) and rotavirus (18.5%). Single infectious agents caused 63.1% of the cases, while mixed infections were detected in 16.7%; in 20.2% of children the cause remained unknown.

    SUMMARY This study compares the seasonality of rotavirus diarrhoeal hospital admissions and its relationship to climatic factors across three Australian cities. Weekly admission of rotavirus diarrhoea (1993–2003) in children aged <5 years and weekly average temperature and relative humidity for each city were modelled using a log-linear model with a cubic trend and season. Interactions were included to test for differences in the effect of temperature and humidity between seasons and between cities. Admissions of rotavirus diarrhoea peaked in winter and spring and were lowest in summer. Higher temperature and humidity in the previous week were associated with a decrease in rotavirus diarrhoeal admissions in three cities. The effects of both temperature and humidity on rotavirus admissions in Brisbane differed across seasons. Strategies to combat outbreaks of rotavirus diarrhoea should take climatic factors and seasonal effects into consideration to plan for the excess seasonal hospital admissions. PMID:17352836

    The water-insoluble carob fraction (fraction insoluble caroube, FIC, Nestlé) has been successfully used in the treatment of infantile diarrhoea. To investigate the efficacy and toxicity of FIC (1970 mg to be taken every 2 hours over a 48-hour period except during sleeping time) in the treatment of travellers' diarrhoea in adults, a double-blind, computer randomized, placebo-controlled study was conducted. Of the 755 volunteers recruited at the Zurich University Vaccination Centre, 628 (83.5%) returned their questionnaires. Among them, 164 (27.7%) had diarrhoea, but only 69 (42%) used the trial medication correctly; the others were rated non-complaint. No significant difference in efficacy (p = 0.12) or adverse effects were observed in the two study groups. In conclusion, FIC, although showed a positive trend, was not efficacious.

    Worldwide infectious diarrhoea, mainly caused by rotavirus and enterotoxigenic Escherichia coli (ETEC), accounts for a large part of deaths in children. ETEC is also the main cause of traveller's diarrhoea. Probiotics are promising for prevention and treatment of diarrhoea, but there is insufficient evidence to support the use of any specific probiotic or probiotics in general. Because of the sensitivity of suckling and weaned piglets for ETEC, piglets are a good model for infectious diarrhoea in infants and traveller's diarrhoea. Just as in human the efficacy of probiotics in diminishing diarrhoea and improving growth in suckling and weaned piglets is not uniform. A piglet model of infectious diarrhoea provides access to intestinal compartments that are not easily accessible in infants. In an in situ piglet model of secretory diarrhoea, the functional physiological response to ETEC and the concomitant host genome response to ETEC and probiotics may be tested. This will provide new insights in the complex crosstalk between ETEC, probiotics and the gut in the future.

    Diarrhoea is common in Intensive Care Unit (ICU) patients, with a reported prevalence of 15-38%. Many factors may cause diarrhoea, including Clostridium difficile, drugs (e.g. laxatives, antibiotics) and enteral feeds. Diarrhoea impacts on patient dignity, increases nursing workload and healthcare costs, and exacerbates morbidity through dermal injury, impaired enteral uptake and subsequent fluid imbalance. We analysed a cohort of 9331 consecutive patients admitted to a mixed general intensive care unit to establish the prevalence of diarrhoea in intensive care unit patients, and its relationship with infective aetiology and clinical outcomes. We provide evidence that diarrhoea is common (12.9% (1207/9331) prevalence) in critically ill patients, independently associated with increased intensive care unit length of stay (mean (standard error) 14.8 (0.26) vs 3.2 (0.09) days, p < 0.001) and mortality (22.0% (265/1207) vs 8.7% (705/8124), p < 0.001; adjusted hazard ratio 1.99 (95% CI 1.70-2.32), p < 0.001) compared to patients without diarrhoea even after adjusting for potential confounding factors, and infrequently caused by infective aetiology (112/1207 (9.2%)) such as Clostridium difficile (97/1048 (9.3%) tested) or virological causes (9/172 (5.7%) tested). Our findings suggest non-infective causes of diarrhoea in ICU predominate and pathophysiology of diarrhoea in critically ill patients warrants further investigation.

    This study, a cross-sectional survey, was conducted to assess how mothers take care of their children with diarrhoea and to develop a model of health-care seeking behaviour. Multistage sampling was used. Mothers whose children aged less than five years had suffered from diarrhoea in the last fortnight were included. Nurses interviewed the mothers to collect data. Variables included in the interview were: mothers' characteristics, children's characteristics, clinical data, treatment given by the mother, maternal health-seeking behaviour and mothers' information about diarrhoea and dehydration. Variables corresponding to the clinical data were grouped to identify dehydration signs and the need for medical care. Dehydration was defined as the presence of two or more of the following reported signs: thirst, sunken eyes, sunken fontanelle, or scanty urine. The need for medical care was defined as the presence of one or more of the following characteristics: illness lasting more than three days, vomiting, fever, bloody diarrhoea or dehydration. A sample of 747 mothers was obtained. Household treatments consisted of herbal teas to stop diarrhoea (52.3%), liquids to prevent dehydration (92.2%), symptomatic drugs (35.2%) and changes in feeding patterns (36.3%), which consisted in suppressing milk and dairy products and interrupting breast feeding (12.2%). Mothers sought medical assistance when they perceived a worsening of clinical conditions. Clinical signs statistically associated with their decision were: bloody diarrhoea, vomiting, illness longer than three days, weight loss, and fever. The signs of dehydration were not associated with health care-seeking because the mother did not recognise them. It is concluded that maternal educational programmes should emphasise, besides the proper use of oral rehydration therapy, teaching mothers to identify signs of dehydration as an indication to seek timely medical care.

    This manuscript extends our previously published work (based on data from one clinic) on the association between three drinking water-treatment modalities (boiling, filtering, and bottling) and diarrhoeal disease in HIV-positive persons by incorporating data from two additional clinics collected in the following year. We conducted a cross-sectional survey of drinking water patterns, medication usage, and episodes of diarrhoea among HIV-positive persons attending clinics associated with the San Francisco Community Consortium. We present combined results from our previously published work in one clinic (n = 226) with data from these two additional clinics (n = 458). In this combined analysis we employed logistic regression and marginal structural modelling of the data. The relative risk of diarrhoea for 'always' vs. 'never' drinking boiled water was 0.68 (95% CI 0.45-1.04) and for 'always' vs. 'never' drinking bottled water was 1.22 (95 % CI 0.82-1.82). Drinking filtered water was unrelated to diarrhoea (1.03 (95% CI 0.78, 1.35) for 'always' vs. 'never' drinking filtered water]. Adjustment for confounding did not have any notable effect on the point estimates (0.61, 1.35 and 0.98 for boiled, bottled, and filtered water respectively, as defined above). The risk of diarrhoea was lower among those consuming boiled water but this finding was not statistically significant. Because of these findings, the importance of diarrhoea in immunocompromised individuals, and the limitations of cross-sectional data further prospective investigations of water consumption and diarrhoea among HIV-positive individuals are needed.

    A 42-year-old woman presented with a 4-year history of worsening diarrhoea that was watery, profuse and confirmed to be secretory in nature. She had tested positive for phenolphthalein on urinary laxative screening but continued to deny laxative usage. Her vasoactive intestinal polypeptide (VIP) level was subsequently found to be markedly elevated. Despite a normal abdominal ultrasound, a computed tomography scan revealed a 5-cm pancreatic tail mass. Octreotide scanning was used to exclude metastatic disease and she went on to have surgical removal of a localized pancreatic vasoactive intestinal polypeptide-oma which resulted in the complete resolution of her diarrhoea.

    Diarrhoea is a common clinical problem for treating clinicians in developing countries. Mostly, it is attributed to malnutrition and infection. We, as clinicians, tend to miss some of cases who have inherited enteropathies because of lack of suspicion and non availability of diagnostic facilities. Here, we report a case of homozygous hypobetalipoproteinaemia in a nine-month-old female patient presenting with chronic diarrhoea and failure to thrive. Simple parental screening of lipid parameters led to correct diagnosis and early intervention in present case. PMID:26816882

The study shows that to a great extent diarrhoea morbidity can be explained by the application of chlorine which does not reach useful levels of concentration during the required time. The article concluded by recommending the improvement of existing treatment plants and investing the necessary resources in new plants to insure the quality of water.

    An increase in waterborne illnesses related to floodings has been reported all over the world, especially in developing countries. In Dhaka City, floodings occur almost every year due to severe rainfall compounded by inadequate sewerage systems. Waterborne illnesses spread easily in an unhygienic environment. This study develops a method to estimate the incidences of diarrhoea associated with floodings using a flooding analysis. We performed a flooding analysis using a numerical flooding simulation model and investigated the relationship between floodwater depth and diarrhoea incidence. The incidence of diarrhoea was assessed through a mortality and morbidity survey conducted in 10 low-income communities in flood-prone areas of Dhaka City. The results revealed that there is a positive correlation between floodwater depth and indices of diarrhoea incidence. This indicates that a flooding analysis method can be used to estimate diarrhoea incidence.

    Obesity is increasing at an alarming rate throughout the world. Today it is estimated that there are more than 300 million obese people world-wide. Obesity is a condition of excess body fat often associated with a large number of debilitating and life-threatening disorders. It is still a matter of debate as to how to define obesity in young people. Overweight children have an increased risk of being overweight as adults. Genetics, behavior, and family environment play a role in childhood overweight. Childhood overweight increases the risk for certain medical and psychological conditions. Encourage overweight children to expand high energy activity, minimize low energy activity (screen watching), and develop healthful eating habits. Breast feeding is protective against obesity. Diet restriction is not recommended in very young children. Children are to be watched for gain in height rather than reduction in weight. Weight reduction of less than 10% is a normal variation, not significant in obesity. PMID:21448410

    Rhabdomyosarcoma is the most common soft-tissue sarcoma in children; it can appear in any part of the body. Its biological behavior varies widely, and despite the absence of specific clinical or radiological characteristics, rhabdomyosarcoma should be taken into account in the differential diagnosis of solid tumors in children. This review focuses primarily on the imaging findings and anatomical distribution of the histological subtypes of childhood rhabdomyosarcoma and secondarily on the differential findings in histological studies.

    Low pathogen diarrhoea is a group-level diagnosis, characterised by non-haemorrhagic diarrhoea. In the current study, the apparent prevalence of low pathogen diarrhoea outbreaks in Danish herds was investigated along with the clinical utility of a laboratory examination for intestinal disease, agreement between three consecutive herd examinations from the same herd and agreement between quantitative PCR results from pooled faecal samples and sock samples. Twenty-four veterinarians submitted faecal and sock samples for quantitative PCR testing from outbreaks of diarrhoea in nursery pigs (n=38 herds) where the farmer or veterinarian had decided that antimicrobial treatment was necessary. The veterinarians were asked to fill in a questionnaire and participate in telephone interviews. The apparent prevalence of low pathogen diarrhoea was 0.18 (95% CL: 0.08-0.34). Agreement between the veterinarians' clinical aetiological diagnosis and the pooled faecal sample was 0.18 (95% CL: 0.08-0.34), and Cohen's Kappa was 0.03 (95% CL: -0.08 to 0.14). Antibiotic treatment or prevention strategies were changed in 0.63 (95% CL: 0.46-0.78) of the herds, and the veterinarians indicated that, for 0.32 (95% CL: 0.18-0.50) of the herds, changes were related to the diagnostic results from the laboratory examination performed in the study. In 0.16 (95% CL: 0.05-0.36) of the herds, the same infections were demonstrated at all three consecutive examinations. No herds had three consecutive diarrhoea outbreaks classified as low pathogen diarrhoea. For the quantitative results (log10 of the summed amounts of Lawsonia intracellularis, Brachyspira pilosicoli, Escherichia coli F4 and F18) agreement between pooled faecal samples and sock samples was evaluated. Lin's concordance correlation coefficient was 0.69 (95% CL: 0.48-0.82), and the mean difference between the two types of samples was -0.38 log10 bacteria/g faeces (SD=1.59log10 bacteria/g faeces; 95% CI: -0.90 to 0.14log10 bacteria/g faeces

    Oral treatment with antimicrobials is widely used in pig production for the control of gastrointestinal infections. Lawsonia intracellularis (LI) causes enteritis in pigs older than six weeks of age and is commonly treated with antimicrobials. The objective of this study was to evaluate the efficacy of three oral dosage regimens (5, 10 and 20mg/kg body weight) of oxytetracycline (OTC) in drinking water over a five-day period on diarrhoea, faecal shedding of LI and average daily weight gain (ADG). A randomised clinical trial was carried out in four Danish pig herds. In total, 539 animals from 37 batches of nursery pigs were included in the study. The dosage regimens were randomly allocated to each batch and initiated at presence of assumed LI-related diarrhoea. In general, all OTC doses used for the treatment of LI infection resulted in reduced diarrhoea and LI shedding after treatment. Treatment with a low dose of 5mg/kg OTC per kg body weight, however, tended to cause more watery faeces and resulted in higher odds of pigs shedding LI above detection level when compared to medium and high doses (with odds ratios of 5.5 and 8.4, respectively). No association was found between the dose of OTC and the ADG. In conclusion, a dose of 5mg OTC per kg body weight was adequate for reducing the high-level LI shedding associated with enteropathy, but a dose of 10mg OTC per kg body weight was necessary to obtain a maximum reduction in LI shedding.

    Malnutrition is associated with a significant impairment of cell-mediated immunity, phagocyte function, immunoglobulin A concentrations and cytokine production. This situation-which is unfortunately very frequent in infants and children from developing countries-leads to a high risk of infection, and often to episodes of diarrhoea, hence aggravating the nutritional status. Fermented milks are known to exert a beneficial influence on the host's health. They act by modulating gut microflora, regulating any alteration of gut mucosa and stimulating immune response. A number of studies have shown that probiotics shorten the duration of diarrhoea and prevent recurrence of other episodes. Furthermore, probiotics can prevent diarrhoea from infection in infants with malnutrition. In addition, it has been shown that cytokines could be used as biological markers of both impaired immune system and the immune stimulation of probiotics. The aim of this review is to update the effect of fermented milks in situations of malnutrition and diarrhoea as a consequence of infection as well as the role of cytokines produced by fermented milks in these deficient conditions.

    Chronic diarrhoea induced by bile acids is common and the underlying mechanisms are linked to homeostatic regulation of hepatic bile acid synthesis by fibroblast growth factor 19 (FGF19). Increasing evidence, including that from several large case series using SeHCAT (selenium homocholic acid taurine) tests for diagnosis, indicates that bile acid diarrhoea (BAD) accounts for a sizeable proportion of patients who would otherwise be diagnosed with IBS. Studies of other approaches for diagnosis of BAD have shown increased bile acid synthesis, increased faecal levels of primary bile acids, dysbiosis and different urinary volatile organic compounds when compared with healthy controls or with other diseases. The role of the ileal hormone FGF19 in BAD has been strengthened: a prospective clinical study has confirmed low FGF19 levels in BAD, and so a test to measure these levels could be developed for diagnosis. In animal models, FGF19 depletion by antibodies produces severe diarrhoea. Bile acids affect colonic function through farnesoid X receptor (FXR) and TGR5 receptors. As well as these effects in the colon, FXR-dependent stimulation of ileal FGF19 production could be a logical mechanism to provide therapeutic benefit in BAD. Further studies of FGF19 in humans hold promise in providing novel treatments for this cause of chronic diarrhoea.

    Few case-control studies have examined possible risk factors for diarrhoeal deaths in under-age-five children in the developing countries. We analysed data from the surveillance system of our diarrhoea treatment centre/hospital for the period 1990-94 on 928 children less than 5 years of age. In univariate analysis, 11 factors were significantly associated with death: lack of breastfeeding, severe malnutrition, complicated diarrhoea, pneumonia, xerophthalmia, duration of diarrhoea 7-14 days, moderate or severe dehydration, recent history of measles, Shigella flexneri infection, maternal illiteracy, and very low household income. Rotavirus diarrhoea was negatively associated with fatal outcome. In the assessment of severe malnutrition, weight-for-height measurement discriminated mortality risk better than weight-for-age or height-for-age indices. Only two factors retained their significance, severe malnutrition and non-breastfeeding in the multivariate analysis with adjusted odds ratio (95% confidence interval) of 84.2 (9.1, 775.9) and 4.2 (1.3, 13.2) respectively.

    A large proportion of diarrhoeal illnesses in children in developing countries are ascribed to an unknown aetiology because the only available methods, such as microscopy and culture, have low sensitivity. This study was aimed at decreasing the diagnostic gap in diarrhoeal disease by the application of molecular techniques. Faecal samples from 158 children with and 99 children without diarrhoea in a hospital in South India were tested for enteric pathogens using conventional diagnostic methods (culture, microscopy and enzyme immunoassays) and molecular methods (six PCR-based assays). The additional use of molecular techniques increased identification to at least one aetiological agent in 76.5 % of diarrhoeal specimens, compared with 40.5 % using conventional methods. Rotavirus (43.3 %), enteropathogenic Escherichia coli (15.8 %), norovirus (15.8 %) and Cryptosporidium spp. (15.2 %) are currently the most common causes of diarrhoea in hospitalized children in Vellore, in contrast to a study conducted two decades earlier in the same hospital, where bacterial pathogens such as Shigella spp., Campylobacter spp. and enterotoxigenic E. coli were more prevalent. Molecular techniques significantly increased the detection rates of pathogens in children with diarrhoea, but a more intensive study, testing for a wider range of infectious agents and including more information on non-infectious causes of diarrhoea, is required to close the diagnostic gap in diarrhoeal disease.

    A longitudinal prospective study of the effect of drainage and sewerage systems on diarrhoea in children aged < 5 years was conducted in 9 poor urban areas of the city of Salvador (population 2.44 million) in north-east Brazil in 1989-90. Due to complex political and administrative reasons, 3 areas had benefited from drainage improvements, 3 from both drainage and sewerage improvements, and 3 from neither. An extensive questionnaire was applied to collect information on each child and on the conditions of the household, and mothers recorded diarrhoea episodes in their children aged < 5 years daily for 1 year, using calendars. Fortnightly home visits were made to collect the data. The incidence of diarrhoea in children in neighbourhoods with drainage was less than two-thirds, and in neighbourhoods with drainage and sewerage less than one-third, of the incidence in neighbourhoods with neither. After controlling for potential confounders, the proportion of children with 'frequent diarrhoea' showed the same significant trend across the study groups. Though the groups were not exactly comparable, more than one child was monitored per household, and it was not possible to rotate fieldworkers between study groups, the study provides evidence that community sanitation can have an impact on diarrhoeal disease, even without measures to promote hygiene behaviour.

    Studies on the rotavirus-associated acute diarrhoeal illness in Jordanian children are non-existent. The present case-control study was conducted to investigate the prevalence of rotavirus diarrhoea among children aged less than 5 years, attending the United Nations Refugee World Aid Clinic in northern Jordan. The potential environmental and behavioural risk factors contributing to the infection were also studied. Using the ELISA technique rotavirus antigens were detected in the stool samples of 35% of the 220 cases of gastroenteritis and in 3% of the control group. The control subjects were matched for age and sex with the cases. The overall prevalence was significantly higher (62%) in children aged less than 24 months [OR = 2.4, 95% CI (1.1-5.1)] than those in the older age groups. Severe cases of diarrhoea were rare. Diarrhoea due to rotavirus was more prevalent during the summer months (June-August). Risk factors for acute diarrhoea in these children are related to the infant feeding practices of using unboiled tap water to prepare the formula milk, and the low educational level of the mothers.

    A health impact evaluation of the Rural Sanitation Pilot Project in Mohale's Hoek district, Lesotho, was conducted from October 1987 to September 1988. A clinic-based case-control design was used to investigate the impact of improved sanitation on diarrhoea morbidity in young children. The results indicate that under-5-year-olds from households with a latrine may experience 24% fewer episodes of diarrhoea than such children from households without a latrine (odds ratio = 0.76; 95% confidence interval, 0.58-1.01). The impact of latrines on diarrhoea was greater in those households that used more water, practised better personal hygiene, and where the mothers had a higher level of education or worked outside the home. In common with studies conducted in Malawi, Philippines, and Sri Lanka, little evidence was found that the relationship between latrine ownership and diarrhoea was confounded by socioeconomic status or environmental variables. For a sample of cases and controls, data on exposure status (presence or absence of a latrine) that were collected by interview at the clinics agreed closely with those obtained by observation during a home visit.

    Diffusely adherent Escherichia coli (DAEC) is thought to cause diarrhoea in children, and so too are other diarrhoeagenic E. coli (DEC); however, the evidence base is inconclusive. DEC pathotypes are differentiated on the basis of their pathogenic features, and thus cannot be quickly identified on selective culture media. Molecular techniques, not readily available in most clinical laboratories, are required to differentiate DEC strains from non-pathogenic E. coli in the stool flora. We report a case of persistent bloody diarrhoea, without fever, in a previously healthy 21-month infant from whom we isolated five DAEC strains. The child's stools movements were loose, with gross blood and mucus; fresh mount analysis revealed numerous faecal leukocytes and erythrocytes. Response to antimicrobial treatment with trimethoprim-sulfamethoxazole was poor despite susceptibility in vitro. Although the patient improved with azithromycin, blood was present in the patient's stools for over 30 days. The severe diarrhoea in this patient might be explained by the fact that these DAEC isolates harboured a siderophore receptor, which allows the bacteria to use iron derived from haem compounds that promote its multiplication. The isolates also induced in vitro secretion of several immunomodulatory cytokines that may account for the patient's loose stools and faecal leukocytes. DAEC may play a greater role than suspected in afebrile children with bloody diarrhoea.

  5. Ethnobotanical survey of medicinal plants used in the treatment of animal diarrhoea in Plateau State, Nigeria

    PubMed Central

    2011-01-01

    Background The use of medicinal plants in the treatment of diseases has generated renewed interest in recent times, as herbal preparations are increasingly being used in both human and animal healthcare systems. Diarrhoea is one of the common clinical signs of gastrointestinal disorders caused by both infectious and non-infectious agents and an important livestock debilitating condition. Plateau State is rich in savannah and forest vegetations and home to a vast collection of plants upheld in folklore as having useful medicinal applications. There is however scarcity of documented information on the medicinal plants used in the treatment of animal diarrhoea in the state, thus the need for this survey. Ten (10) out of 17 Local Government Areas (LGAs), spread across the three senatorial zones were selected. Farmers were interviewed using well structured, open-ended questionnaire and guided dialogue techniques between October and December 2010. Medicinal plants reported to be effective in diarrhoea management were collected using the guided field-walk method for identification and authentication. Results A total of 248 questionnaires were completed, out of which 207 respondents (83.47%) acknowledged the use of herbs in diarrhoea management, while 41 (16.53%) do not use herbs or apply other traditional methods in the treatment of diarrhoea in their animals. Medicinal plants cited as beneficial in the treatment of animal diarrhoea numbered 132, from which 57(43.18%) were scientifically identified and classified into 25 plant families with the families Fabaceae (21%) and Combretaceae (14.04%) having the highest occurrence. The plant parts mostly used in antidiarrhoeal herbal preparations are the leaves (43.86%) followed by the stem bark (29.82%). The herbal preparations are usually administered orally. Conclusion Rural communities in Plateau State are a rich source of information on medicinal plants as revealed in this survey. There is need to scientifically ascertain

    This study surveyed the prevalence of massive numbers of Cyniclomyces guttulatus in faecal samples from healthy dogs (18%) and dogs with chronic diarrhoea (14%) suggesting that this yeast has no clinical significance. Subsequently, a total of 57 referred dogs with chronic diarrhoea were selected because they excreted massive numbers of C. guttulatus and their initial diagnostic work-up yielded no other direct clues explaining their diarrhoea. Treatment with nystatin did not result in any clinical response in 36 out of these 57 dogs (63%), although they no longer shed the yeast. However, a response was noted in the remaining 21 (37%) dogs: 13 were 'responders', in that their diarrhoea subsided for more than two weeks and the faeces were cleared of the yeast. However, three of these dogs relapsed repeatedly, with signs of diarrhoea and massive shedding of the yeast. The other eight dogs were 'incomplete responders', whereby faecal quality initially normalised, but diarrhoea relapsed within two weeks, whilst still not shedding the yeast. In these cases, further diagnostic work up revealed other co-causes of diarrhoea. It was concluded that there was no direct evidence that C. guttulatus is a primary pathogen. However, the results of the prospective treatment study suggest that a possible role in a minority of cases, perhaps as an opportunist, cannot be ruled out.

    The 1998 flood in Bangladesh ravaged approximately 60% of the land and affected over 30 million people. The aim of this study is to examine the impact of the flood on the health of the communities affected and to explore factors associated with episodes of diarrhoea. We conducted structured interviews with 517 people in two districts that had been affected in October 1998, when the flood water level was at its peak. Of the 517 respondents, 98.3% developed health problems or found that existing health problems were exacerbated. Many perceived that their general health condition was 'much worse' (16.9%) or 'worse' (64.3%). The most prevalent condition was fever (63.6%), followed by respiratory problems (46.8%), diarrhoea (44.3%), and skin problems (41.0%). Only 1.0% and 6.7% of the respondents treated water before drinking, by boiling and chlorination, respectively, although water collected from tube-wells (93.2%) and rivers (6.0%) was perceived by 75.0% of the respondents to be contaminated. Factors associated with developing or worsening diarrhoea were as follows; the number of family members, poor economic status, a lack of distribution of water purification tablets, the type of water storage vessels, not putting a lid on the vessel, no use of latrines, perceived change of drinking water, food scarcity, and worries about the future. In logistic regression analysis, men, poor economic status, lack of distribution of water purification tablets, and the type of water storage vessels had a significant association with diarrhoea. The 1998 Bangladesh flood had a substantial impact on the health of communities. Diarrhoea was associated with socioeconomic status, water handling and household sanitation. There ought to be more emphasis on health education in the pre-disaster period in order to empower communities against floods.

    This study was conducted to evaluate the anti-diarrhoeal activity of Bacillus clausii strain UBBC 07 in patients suffering from acute diarrhoea. A total of 27 patients (average age of 35.44±8.08 years) with acute diarrhoea were included in a prospective, Phase II clinical study after informed consent and ethical committee approval. The criteria included for all subjects were ≥3 loose stool motions within 24 hours and for more than 7 days. All patients were assigned to receive one capsule of B. clausii strain UBBC-07 (containing 2×109 cfu) two times a day for a period of 10 days. Efficacy assessment of duration of diarrhoea, frequency of defecation, abdominal pain and stool consistency were tested on days 1, 3, 6 and 10. Safety was evaluated by assessing the incidence and type of adverse effects such as increase in blood pressure and pulse rate, physical examination and clinical laboratory tests, i.e. complete blood count, serum glutamic pyruvic transaminase, serum creatinine, and stool examination and microscopy, on day 1 and day 10. The results of this study clearly showed that the mean duration of diarrhoea decreased from 34.81±4.69 to 9.26±3.05 (P<0.0001) min per day, the frequency of defecation also decreased from 6.96±1.05 to 1.78±0.50 (P<0.0001) times per day, abdominal pain decreased from 3.22±0.93 (severe) to 0.74±0.71 (absent) (P<0.0001), and stool consistency improved from 3.93±0.38 (watery) to 1.22±0.42 (soft) (P<0.0001). No significant change in safety parameters were observed during treatment. This study shows that the B. clausii strain UBBC-07 can potentially be effective in alleviating the symptoms of diarrhoea without causing any adverse effects.

    In order to assess the epidemiological and clinical characteristics and changing nutritional status of infants suffering from acute diarrhoea, 103 infants with such diarrhoea and the same number of age-matched controls were investigated at the Universidade Federal do Rio Grande do Norte's Paediatric Hospital, in north-eastern Brazil. Each child with diarrhoea was given oral rehydration or, in the severe cases, intravenous rehydration. Each subject was checked for enteropathogens and his or her weight, height and weight-for-height, weight-for-age and height-for-age Z-scores were evaluated immediately after any clinical dehydration had been corrected and 30 days later. In the infants aged <6 months, a diet that included foods other than breast milk (odds ratio=9.41), including one in which breast milk was supplemented with other foods (odds ratio=4.69), was found to be statistically associated with diarrhoea. The enteropathogens found most commonly in the children with diarrhoea were rotavirus (36.9%), enteropathogenic Escherichia coli (11.6%) and Shigella (11.6%). Just four (5.2%) of the 77 cases with adequate follow-up showed persistent diarrhoea. At presentation or as soon as any clinical dehydration had been corrected, the infants with diarrhoea had significantly lower weights and weight-for-height and weight-for-age Z-scores than the controls. Thirty days later, however, the weight-for-height and weight-for-age Z-scores of the cases had increased significantly, to the point when they were not significantly different from the baseline values for the controls. The negative consequences of diarrhoea on weight-for-height and weight-for-age Z-scores and the recovery of these parameters after 30 days with rehydration reflect the acute but reversible influence of diarrhoea on infant nutritional status.

    Poor hygiene practices are among the risk factors for the transmission of childhood diarrhea, a leading cause of morbidity and mortality in Nicaragua. Findings are reported from a prospective follow-up study in rural Nicaragua of the effect of a number of hygiene practices upon diarrheal disease in children under age 2 years old. 172 families, of whom half had experienced a higher than expected rate of diarrhea in their children and the other half a lower rate, participated. Hygiene behavior was observed over 2 mornings and diarrhea incidence was recorded with a calendar over the course of 5 months. Of 46 good practices studied, 39 were associated with a lower risk of diarrhea, 5 were unrelated, and a higher risk was observed for 2. The washing of hands, domestic cleanliness, and the use of a diaper/underclothes by the child had the strongest protective effect against diarrhea. Mothers with more than 3 years of primary school education and in a comparatively better economic position, including having a radio, exhibited comparatively better general hygiene behavior. Education had a slightly stronger effect when a radio was present. However, individual hygiene behavior seems to be highly variable compared to the consistent behavior of the overall community. Appropriate indicators of hygiene behavior were domestic cleanliness and the use of a diaper or underclothes by the child.

    Objective Preventive zinc supplementation in the form of tablets or syrup reduces the incidence of diarrhoea and acute lower respiratory tract infections (RTI), but its effect on malaria is inconsistent. When zinc is administered with other micronutrients or foods, its effect is also uncertain. We assessed the effects of different amounts and sources of zinc on the frequency of diarrhoea, malaria, fever and RTI in young children. Design, setting and populations This community-based, double-blind, placebo-controlled, cluster-randomised trial of 2435 children 9 months of age was carried out between April 2010 and July 2012 in rural southwestern Burkina Faso. Interventions Participants were randomly assigned at the concession level to receive daily 1 of 4 interventions for 9 months: (1) 20 g small-quantity lipid-based nutrient supplement (SQ-LNS) without zinc and placebo tablet, (2) 20 g SQ-LNS with 5 mg zinc and placebo tablet, (3) 20 g SQ-LNS with 10 mg zinc and placebo tablet or (4) 20 g SQ-LNS without zinc and 5 mg zinc tablet. Participants were visited weekly in their homes for morbidity surveillance for 9 months, and those with uncomplicated diarrhoea and malaria received treatment from the study field workers in the community. Main outcomes Incidence and longitudinal prevalence of diarrhoea, malaria, fever, and lower and upper RTI by intervention group. Results The incidence of diarrhoea, malaria and fever was 1.10 (±1.03 SD), 0.61 (±0.66 SD) and 1.49 (±1.12 SD) episodes per 100 child-days at risk, respectively, and did not differ by intervention group (p=0.589, p=0.856 and p=0.830, respectively). The longitudinal prevalence of acute lower RTI (0.1%; 95% IC 0.1–0.2%) and of upper RTI (7.8%; 95% IC 7.1–8.4%) did not differ among groups (p=0.234 and p=0.501, respectively). Conclusions Inclusion of 5 or 10 mg zinc in SQ-LNS and provision of 5 mg zinc dispersible tablet along with SQ-LNS had no impact on the incidence of diarrhoea

    2016-01-01

    Leukemia is the most common pediatric cancer, affecting 3,800 children per year in the United States. Its annual incidence has increased over the last decades, especially among Latinos. Although most children diagnosed with leukemia are now cured, many suffer long-term complications, and primary prevention efforts are urgently needed. The early onset of leukemia – usually before age five – and the presence at birth of “pre-leukemic” genetic signatures indicate that pre- and postnatal events are critical to the development of the disease. In contrast to most pediatric cancers, there is a growing body of literature – in the United States and internationally – that has implicated several environmental, infectious, and dietary risk factors in the etiology of childhood leukemia, mainly for acute lymphoblastic leukemia, the most common subtype. For example, exposures to pesticides, tobacco smoke, solvents, and traffic emissions have consistently demonstrated positive associations with the risk of developing childhood leukemia. In contrast, intake of vitamins and folate supplementation during the pre-conception period or pregnancy, breastfeeding, and exposure to routine childhood infections have been shown to reduce the risk of childhood leukemia. Some children may be especially vulnerable to these risk factors, as demonstrated by a disproportionate burden of childhood leukemia in the Latino population of California. The evidence supporting the associations between childhood leukemia and its risk factors – including pooled analyses from around the world and systematic reviews – is strong; however, the dissemination of this knowledge to clinicians has been limited. To protect children’s health, it is prudent to initiate programs designed to alter exposure to well-established leukemia risk factors rather than to suspend judgement until no uncertainty remains. Primary prevention programs for childhood leukemia would also result in the significant co

    Rotavirus-specific subclass antibody responses and cytokines, tumour necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma), interleukin-8 (IL-8), and IL-10, were measured in children 7-24 months of age with rotavirus diarrhoea (n = 29); the responses were compared with children with watery diarrhoea from whom no enteric pathogens were isolated (controls; n = 11). All children had diarrhoea for < 5 days and were enrolled from the Dhaka Hospital of the Centre for Health and Population Research. Samples of blood and stools were collected on the day of enrollment and 18-21 days after the onset of diarrhoea. Children showing a > or = 4-fold rise in antibody titre between the acute and convalescent stages were considered to have a response. The numbers of children with rotavirus-specific IgA and IgA1 responses in stool were similar in the two groups of children. In the plasma, more children with rotavirus diarrhoea had rotavirus-specific IgA, IgA1, IgG, IgG1, and IgG3 responses than did control children (P = 0.049, 0.007, 0.001, 0.002, and 0.012, respectively). IgA2 was not detectable. Among cytokines measured in supernatants from peripheral blood mononuclear cells (PBMCs) cultured for 6 and 24 hr, IFN-gamma was the only cytokine that was higher in children with rotavirus diarrhoea compared with controls (P = 0.013). Severity of illness did not correlate with nutritional status or antibody titres, but severity did correlate with TNF-alpha during the acute stage of illness. IFN-gamma correlated positively with IgG1 titres. These findings suggest a role for IFN-gamma in the pathogenesis of rotavirus infection, but this needs confirmation by other studies. The immune responses described are relevant to future vaccine trials, as immune responses in vaccinees should mimic those in natural infection.

    2015-01-01

    Humans often judge others egocentrically, assuming that they feel or think similarly to themselves. Emotional egocentricity bias (EEB) occurs in situations when others feel differently to oneself. Using a novel paradigm, we investigated the neurocognitive mechanisms underlying the developmental capacity to overcome such EEB in children compared with adults. We showed that children display a stronger EEB than adults and that this correlates with reduced activation in right supramarginal gyrus (rSMG) as well as reduced coupling between rSMG and left dorsolateral prefrontal cortex (lDLPFC) in children compared with adults. Crucially, functional recruitment of rSMG was associated with age-related differences in cortical thickness of this region. Although in adults the mere presence of emotional conflict occurs between self and other recruited rSMG, rSMG-lDLPFC coupling was only observed when implementing empathic judgements. Finally, resting state analyses comparing connectivity patterns of rSMG with that of right temporoparietal junction suggested a unique role of rSMG for self-other distinction in the emotional domain for adults as well as for children. Thus, children’s difficulties in overcoming EEB may be due to late maturation of regions distinguishing between conflicting socio-affective information and relaying this information to regions necessary for implementing accurate judgments.

    Diarrhoea is a common, debilitating and potentially life threatening toxicity of many cancer therapies. While the mechanisms of diarrhoea induced by traditional chemotherapy have been the focus of much research, the mechanism(s) of diarrhoea induced by small molecule ErbB TKI, have received relatively little attention. Given the increasing use of small molecule ErbB TKIs, identifying this mechanism is key to optimal cancer care. This paper critically reviews the literature and forms a hypothesis that diarrhoea induced by small molecule ErbB TKIs is driven by intestinal chloride secretion based on the negative regulation of chloride secretion by ErbB receptors being disrupted by tyrosine kinase inhibition.

However, since 2008 it seems that a new neonatal diarrhoeic syndrome unresponsive to antibiotics and common management practices has emerged. Routine laboratory examinations have not detected any pathogen related to this syndrome. The primary purpose of this study was to evaluate if well-known enteric pathogens could be associated with outbreaks of neonatal diarrhoea, thus question the hypotheses of a new syndrome. Furthermore, we wanted to evaluate macroscopic and microscopic findings associated with these outbreaks and if possible propose a preliminary piglet-level case-definition on syndrome New Neonatal Porcine Diarrhoea syndrome (NNPDS). Results Four well-managed herds experiencing neonatal diarrhoea with no previously established laboratory conclusion and suspected to suffer from New Neonatal Porcine Diarrhoea Syndrome, were selected. Within these herds, 51 diarrhoeic and 50 non-diarrhoeic piglets at the age of three to seven days were necropsied and subjected to histological and microbiological examination. Faeces were non-haemorrhagic. Neither enterotoxigenic E. coli, Clostridium perfringens type A or C, Clostridium difficile, rotavirus, coronavirus, Cryptosporidium spp, Giardia spp, Cystoisospora suis nor Strongyloides ransomi were associated with diarrhoea in the investigated outbreaks. Macroscopically, the diarrhoeic piglets were characterized by filled stomachs and flaccid intestines without mucosal changes. The predominant histological lesions were villous atrophy in jejunum and ileum. Epithelial lesions in colon were seen in one third of the case piglets. Conclusions The results of the study supported the hypothesis that a new neonatal porcine diarrhoea was present in the investigated herds, since no known pathogen(s) or management factors could explain the diarrhoeal outbreaks. Based on the findings in the four

    The prevalence of infection caused by different categories of diarrhoeagenic E. coli (DEC) strains, including enteroaggregative (EAEC), enteropathogenic (EPEC), enterotoxigenic (ETEC), enteroinvasive (EIEC) and enterohaemorrhagic (EHEC) E. coli, in children who suffered from diarrhoea (n = 3943) or did not have diarrhoea (n = 1026) were analysed in two areas in Bolivia over a period of 4 years. We also analysed the seasonality of DEC infections and severity of diarrhoea in children with DEC infection and compared antibiotic resistance in DEC strains isolated from children with and without diarrhoea. Stool samples were analysed for the presence of DEC by culturing followed by PCR. The most prevalent DEC categories in samples from the children were: EAEC (11.2 %); ETEC (6.6 %); EPEC (5.8 %); and EIEC and EHEC (<1 %). DEC strains were isolated significantly more often from diarrhoea cases (21.6 %) than from controls (17.6 %; P = 0.002). The number of children with diarrhoea associated with EAEC, EPEC and ETEC infections peaked in the Bolivian winter (April-September), although the proportion of DEC-positive stool samples was higher during the warm rainy season (October-March). High levels of antibiotic resistance were detected among the DEC strains. In particular, resistance to tetracycline and sulfamethoxazole-trimethoprim was significantly higher in strains isolated from individuals with diarrhoea than in samples from controls. The severity of disease in children infected with EAEC, EPEC and ETEC varied from mild to severe diarrhoea, although disease severity did not differ significantly between the different DEC categories. ETEC, EPEC and EAEC are commonly found in Bolivia and may cause severe disease in children.

  2. Crofelemer: a review of its use in the management of non-infectious diarrhoea in adult patients with HIV/AIDS on antiretroviral therapy.

    Crofelemer (Fulyzaq) is a botanical drug substance (oligomeric proanthocyanidin) extracted from the stem bark latex of the Croton lechleri tree. Crofelemer undergoes minimal systemic absorption following oral administration; it acts locally within the gastrointestinal (GI) tract by inhibiting the two principal chloride ion channels in the luminal membrane of enterocytes. Crofelemer is the first (and so far only) agent to be approved by the US FDA specifically for the symptomatic relief of non-infectious (i.e. secretory) diarrhoea in adult patients with HIV/AIDS on antiretroviral therapy (ART). This approval was based on findings from the ADVENT study, a large (n = 376 randomized patients), multicentre, phase III trial in which the recommended dosage of oral crofelemer (125 mg twice daily) significantly reduced secretory diarrhoea in HIV-positive individuals on ART compared with placebo, as assessed over a 4-week period. Crofelemer was generally well tolerated in ADVENT (which included a 5-month placebo-free extension phase) and a 48-week, open-label, phase III safety study; infections and GI disorders were the most frequently reported treatment-emergent adverse events (TEAEs) in patients receiving the drug. Of note, the overall incidence of TEAEs was similar in the crofelemer and placebo groups during the 4-week placebo-controlled phase of ADVENT. Treatment with crofelemer had no appreciable effect on immune parameters, such as HIV viral load and CD4+ cell counts.

    Effects of probiotic Enterococcus faecium DMS 10663 NCIMB 10415 on diarrhoea and performance of sucking piglets were evaluated in a double-blind, placebo-controlled study. Piglets from treatment group (TG, n=56) and placebo group (PG, n=53) sows were included in the study. Immediately after birth and at day 2 and 3 post natum, each of the TG piglets received 2.8×10(9) colony forming units (cfu) per os. From day 4 until weaning (day 26), 1.26×10(9) cfu E. faecium/piglet were given twice a day via a liquid additive. Piglets already suffering from diarrhoea additionally got a glucose-electrolyte solution enriched with 2.9×10(8) (week 1) and 5.8×10(8) (week 2) cfu E. faecium/day. PG piglets received corresponding placebo preparations. A score was defined to characterise the severity of diarrhoea, including accompanying symptoms. The counts of viable born, stillborn and weaned piglets were similar in TG and PG litters (P>0.05). The probiotic treatment mitigated incidence and severity of diarrhoea (P<0.05) with no impact on diarrhoea length (P>0.05). Probiotic treatment improved daily weight gain (P<0.05) yet with no provable effect on body weight at weaning (P>0.05). The additional supply of E. faecium in piglets suffering from diarrhoea had no further beneficial effect.

    The clinico-pathological features of 515 adult patients admitted to a major Regional Infectious Diseases Unit in United Kingdom with the symptom complex of diarrhoea were compared to the pathogens detected in their stool specimens. Routine clinical examination supported by basic pathological and laboratory investigations identified 138 (28%) in whom the cause of diarrhoea was extragastrointestinal or non-infectious gastrointestinal. Of the 351 patients (72%) with infectious gastroenteritis 72 (21%) had campylobacter, 59 (17%) had salmonella (22% bacteraemic) and 16 (5%) shigella. Clostridium difficile toxin accounted for a further 15 (4%)--antibiotics had been the antecedent cause in only one half of these. Routine microscopical examination of the faeces for red and white cells distinguished many with "culture positive" diarrhoea from those with "culture negative" infectious diarrhoea. Although there are no clinico-pathological features which are unique to a particular pathogen and unequivocally suggest a particular pathogen, certain features did tend to present more often in association with particular microorganisms, and this knowledge may suggest a bacterial diagnosis whilst awaiting the definitive results of stool microbiology. These features include prior antimicrobial therapy with positive sigmoidoscopical/histological features: Cl. difficile; protracted diarrhoea in elderly severely dehydrated patients: salmonellosis; foreign travel in males with bloody diarrhoea: shigellosis; abdominal pain in younger patients with a small degree of vomiting: campylobacteriosis. Early diagnosis may then prove useful in rationalizing initial therapy, particularly the appropriate use of antimicrobials.

    Jasminum amplexicaule Buch.-Ham. (Oleaceae) has been commonly used in the traditional medicine in dysentery, diarrhoea and bellyache in China. In the present work, the methanol extract of Jasminum amplexicaule and different fractions of this extract were studied for anti-diarrhoea and analgesic activities. The anti-diarrhoea activities were investigated using castor oil-induced, magnesium sulphate-induced diarrhoea models, antienteropooling assay and gastrointestinal motility models in mice. The analgesic activities were studied using hot-plate, writhing and formalin models in mice. At the doses of 100, 200 and 400mg/kg, the methanol extract (ME) showed significant and dose-dependent anti-diarrhoea and analgesic activity in these models. The chloroform fraction (CHF), ethyl acetate fraction (EAF) and the residual methanol fraction (RMF) exhibited similar activity using a dose of 200mg/kg in these models. The pharmacological activities of the n-butanol fraction (BUF) were lesser than the ME extract and other fractions. These results may support the fact that this plant is traditionally used to cure diarrhoea and pain.

    Diarrhoea is a major cause of morbidity and mortality in rural communities in Africa, particularly in children under the age of five. This calls for the development of cost effective alternative strategies such as the use of herbal drugs in the treatment of diarrhoea in these communities. Expenses associated with the use of orthodox medicines have generated renewed interest and reliance on indigenous medicinal plants in the treatment and management of diarrhoeal infections in rural communities. The properties of many phenolic constituents of medicinal plants such as their ability to inhibit enteropooling and delay gastrointestinal transit are very useful in the control of diarrhoea, but problems such as scarcity of valuable medicinal plants, lack of standardization of methods of preparation, poor storage conditions and incertitude in some traditional health practitioners are issues that affect the efficacy and the practice of traditional medicine in rural African communities. This review appraises the current strategies used in the treatment of diarrhoea according to the Western orthodox and indigenous African health-care systems and points out major areas that could be targeted by health-promotion efforts as a means to improve management and alleviate suffering associated with diarrhoea in rural areas of the developing world. Community education and research with indigenous knowledge holders on ways to maximise the medicinal potentials in indigenous plants could improve diarrhoea management in African rural communities.

    Citrobacter rodentium is a natural mouse pathogen widely used as a model for enteropathogenic and enterohemorrhagic Escherichia coli infections in humans. While C. rodentium causes self-limiting colitis in most inbred mouse strains, it induces fatal diarrhoea in susceptible strains. The physiological pathways as well as the genetic determinants leading to susceptibility have remained largely uncharacterized. Here we use a forward genetic approach to identify the R-spondin2 gene as a major determinant of susceptibility to C. rodentium infection. Robust induction of R-spondin2 expression during infection in susceptible mouse strains causes a potent Wnt-mediated proliferative response of colonic crypt cells, leading to the generation of an immature and poorly differentiated colonic epithelium with deficiencies in ion-transport components. Our data demonstrate a previously unknown role of R-spondins and Wnt signalling in susceptibility to infectious diarrhoea and identify R-spondin2 as a key molecular link between infection and intestinal homoeostasis.

    This study investigated the prevalence of unusual infant feeding practices among 204 mothers of infants aged 1-12 months, who were admitted with acute diarrhoea to the only two national hospitals in Kuwait. Ninety per cent of the mothers boiled water to prepare a powdered milk formula, but only 15% boiled water for drinking. Thirty nine infants (19%) were admitted more than once. Better family state in terms of socioeconomic class, maternal education, and breast feeding gave some protection against re-admission, though this was not significant. It seems that the condition of drinking water is an important cause of diarrhoea and hence of re-admission. The number of re-admissions was twice as high among infants drinking unboiled (unfiltered or mineral) water than among those drinking boiled or unboiled but filtered water. Breast feeding is protective if no extra water is given.

    Phage therapy has been previously tried for treatment of diarrhoea in calves, pigs and lambs but those trials were conducted without any detailed information of used phages. Here, we report isolation of a broad-spectrum phage which showed bactericidal activity against 47.3 % of calf diarrhoeal isolates of Escherichia coli, in vitro. The isolated phage resembled the characteristics of Myoviridae family and showed ~97 % similarity with earlier reported bacteriophages of sub family-Tevenvirinae, genus-T4-like virus, based on nucleotide sequence of major head protein-gp23 gene. The phage exhibits the potential to be used as drug substitute tool against E. coli causing diarrhoea in cattle in farm environments.

    Cystoisospora belli, formerly known as Isospora belli, protozoal parasite endemic to many regions of the world including the Caribbean, Central and South America, Africa, and South-East Asia. It is frequently encountered in patients with acquired immunodeficiency syndrome (AIDS) and is considered to be an AIDS-defining illness. Chronic severe watery diarrhoea due to C. belli has also been reported in other immunodeficiency states. C. belli infection in immunosuppressed patients has rarely been described. We describe severe diarrhoea due to C. belli in a human immunodeficiency virus-negative renal transplant recipient on immunosuppressive drugs. Oocysts of C. belli were detected in direct smear preparation of the diarrheic stool sample of the patient. The patient responded to combination treatment with Bactrim-double-strength (trimethoprim-sulfamethoxazole) and Nitazoxanide.

    Bovine Viral Diarrhoea Virus (BVDV) is responsible worldwide for severe economic losses on cattle farms. BVDV is an RNA virus with a high genome variability having practical consequences on epidemiology, diagnosis and disease control. Genetic monitoring was suggested as the first step in BVDV control. Thirty-seven Bovine Viral Diarrhoea Viruses were identified in persistently infected cattle, mucosal disease-affected animals and in bulk milk, and were characterised genetically. The 5'UTR region was amplified and sequenced, and a phylogenetic analysis was carried out comparing all the Italian sequences of BVDV available from the Genbank database. An unusual number of persistent infected animals was evidenced on more than one farm. Phylogenetic analysis attributed all our viruses to BVDV type I and distinguished four different subgroups inside this genotype. Analysis of old and new viruses revealed the circulation of viruses classified in subgroups BVDV Ia and Ij never reported in Italy.

    Forty-eight cases of chronic diarrhoea in children seen at King Khalid University Hospital over a 5-year period were analysed. The mean age at presentation was 1.8 years (range 0.08-10 years); 34 were boys and 14 girls. Forty-four patients were Saudi and four were non-Saudi Arabs. Most children presented with failure to thrive and pallor. The aetiological factors identified were: the post-gastro-enteritis syndrome with or without lactose intolerance in 16 (33%); coeliac disease in ten (21%); congenital chloride diarrhoea in five (10%); glucose-galactose malabsorption and acrodermatitis enteropathica, each in three (6%); ulcerative colitis, intestinal lymphangiectasia, cow's milk protein intolerance and ataxia telangiectasia, each in two (4%); and giardiasis, immune deficiency and cystic fibrosis, each in one (2%). Five children died.

    Although some studies showed the vulnerability of human health to climate change (e.g. 22.000 to 45.000 excess mortality cases during the heat waves in Europe, or the association of malaria outbreaks with El Niño) a clear quantification of the increased risks attributable to climate change is often lacking. Even more complicated are the assessments of the adaptation measures for this sector. Adaptation measures are in most cases very site specific. We discuss the impact of climate change on diarrhoea as a representative of waterborne disease affecting human health in the Ganges basin of Northern India. India is by far the leading country when it comes to child mortality under five years caused by diarrhoea and accounted for 386.600 deaths in 2007. Estimates on the increased risk of diarrhoea as a result of increased temperature in the 2030ies range between 8-11%. Uncertainties around these estimates mainly relate to the few studies that have characterized the exposure-response relationship and inter-model discrepancy of climate models. The influence of other climate parameters than temperature on diarrhoea in the future has not been assessed. As empirical studies and surveillance data for India are lacking we developed a conceptual framework for climate exposure-response relationships based on a literature review and applied it to future climate projections for the Ganges basin. Four climate variables are analysed: temperature, increased/extreme precipitation, decreased precipitation/droughts and relative humidity. In an analysis of reports on diarrhoea outbreaks we show the spatial and temporal distribution over the subcontinent. Most cases of diarrhoea occur during the hot summer (23%) and the wet and humid monsoon (57%) months. These reports often suggest sewage and pipe leakage as the leading cause of the local outbreaks. We demonstrate the applicability of the conceptual framework for the two districts in West Bengal, North and South 24 Parganas. All climate

Numerous trophozoites, atypical for Giardia sp., were detected on a direct faecal examination, in addition to Giardia cysts. Although the failure to thrive and diarrhoea resolved following treatment for giardiasis, further diagnostic tests performed on faecal specimens from the kitten and 15 other Ocicats from the same cattery, including culture of trophozoites in In Pouch medium, PCR testing and molecular sequencing of PCR amplicons, confirmed infection with Tritrichomonas cf. foetus. This is the first report in Australia of feline trichomoniasis, which appears to be an emerging infectious disease of cats. Pertinent information regarding the clinical features, diagnosis, therapy, and potential source of feline trichomoniasis within Australia are discussed.

    Most laxatives, if used intermittently in the absence of contraindications, are relatively safe. Bulking agents may diminish absorption of some minerals and drugs, but this is not usually clinically significant. Ispaghula can cause serious allergic reactions. The chronic ingestion of stimulant laxatives has been blamed for the development of the 'cathartic colon', but there are no definitive studies which have demonstrated this. Dantron (danthron) preparations should only be used in older patients and the terminally ill because of the risk of hepatotoxicity with this drug. Oral oxyphenisatine should no longer be used. Senna would appear to be the stimulant laxative of choice during pregnancy and lactation. Bisacodyl is the polyphenolic derivative of choice. Lactulose, sorbitol and lactilol rarely cause significant adverse effects. Magnesium salt laxatives and phosphate enemas can cause serious metabolic disturbances in babies and young children. Liquid paraffin is contraindicated if there is any risk of aspiration. Interference with the absorption of fat soluble vitamins would not appear to be clinically significant. Docusate sodium may potentiate the hepatotoxicity of other drugs, but reports of this are rare. The role of cisapride in constipation has not been established. Antidiarrhoeal drugs are second line drugs whose use is aimed at minimising inconvenience and discomfort. No antidiarrhoeals can be recommended for children under 4 years of age. Loperamide is the drug of choice in older children and adults. The atropine component of diphenoxylate/atropine combinations can cause significant adverse effects. Bismuth salicylate is an inconvenient treatment for travellers' diarrhoea as large frequent doses of the liquid formulation are needed. Some bismuth can be absorbed and there is the potential to cause encephalopathy. Octreotide, methysergide and cholestyramine have a role for specific causes of diarrhoea only. Octreotide is effective in high output states

    Introduction. Cytolethal distending toxins (CDTs), encoded by cdt genes, have DNase activity leading to cellular and nuclear distension, resulting in irreversible cell cycle arrest and apoptosis of target cells. cdt-positive Escherichia coli strains have been isolated from children with diarrhoea. There is, however, scant information on the prevalence and clinical presentation of diarrhoeal disease caused by these strains. Furthermore, toxin production of cdt-positive strains is rarely confirmed. We report five young children with diarrhoea caused by CDT-producing E. coli in whom stools were negative for other bacterial or enteric pathogens. Case presentation. On admission to hospital, all children presented watery diarrhoea with high stool output (range 7–20 stools/24 h); five had fever of 38 °C or more and four presented vomiting. Dehydration was present in four patients, one of whom had hypovolaemic shock; one child also presented hyponatraemia and hypokalaemia. In two children, cdt-positive strains were classified as typical and atypical enteropathogenic E. coli, and the remaining three harboured cdt-positive strains that did not belong to any diarrhoeagenic pathogroup. One cdt-positive strain from each case was characterized by a CDT cytotoxic assay and a cdt type-specific PCR. All strains produced the characteristic cellular intoxication due to CDT. Two strains carried the cdt-I, one cdt-III, one cdt-IV, and one concurrently had cdt-I, cdt-II and cdt-III genes. Conclusion. Our results suggest that CDT-producing E. coli strains are an infrequent, albeit significant, cause of severe diarrhoeal illness in children. Future research should measure the true burden of cdt-positive E. coli diarrhoea among children. PMID:28348804

    OBJECTIVE: Inadequate water and sanitation services adversely affect the health and socioeconomic development of communities. The Water and Sanitation Extension Programme (WASEP) project, undertaken in selected villages in northern Pakistan between 1997 and 2001, was designed to deliver an integrated package of activities to improve potable water supply at village and household levels, sanitation facilities and their use, and awareness and practices about hygiene behaviour. METHODS: A case-control study was conducted during July-September 2001 to evaluate whether, after selected confounders were controlled for, children aged <6 years with diarrhoea were more or less likely to reside in villages that participated in the project than in villages that did not participate. Descriptive and logistic regression analyses were performed. FINDINGS: Children not living in WASEP villages had a 33% higher adjusted odds ratio for having diarrhoea than children living in WASEP villages (adjusted odds ratio, 1.331; P<0.049). Boys had 25% lower odds of having diarrhoea than girls (adjusted odds ratio, 0.748; P<0.049). A 2.6% decrease was found in the odds of diarrhoea for every yearly increase in the mother's age (adjusted odds ratio, 0.974; P<0.044) and a 1.4% decrease for every monthly increase in the child's age (adjusted odds ratio, 0.986; P<0.001). CONCLUSIONS: The findings in this study may help refine the approach to future water, sanitation, and hygiene initiatives in northern Pakistan. The integrated approach taken by WASEP, which incorporates engineering solutions with appropriate education to maximize facility usage and improve hygiene practices, is a useful example of how desired health benefits can be obtained from projects of this type.

    Background Obesity is one of the main determinants of avoidable disease burden. To implement a program by university students acting as “health promoting agents” (HPAs) and to evaluate the effects on obesity prevalence of the primary-school-based program that promotes healthy lifestyle, including dietary and physical activity recommendations over 28 months. Methods Two school clusters were randomly assigned to intervention (24 schools, 1,222 pupils) or control (14 schools, 717 pupils); 78% of pupils were Western European. Mean age (±SD) was 8.4 ± 0.6 years (49.9% females) at baseline. Generalized linear mixed models were used to analyze differences in primary outcome between both groups. Data collected included body mass index (BMI) every year. Dietary habits and lifestyle questionnaires were filled in by the parents at baseline and at the end of the study. The interventions focused on eight lifestyle topics covered in 12 activities (1 hour/activity/session) implemented by HPAs over 3 school academic years. Results At 28 months, obesity prevalence in boys was decreased −2.36% in the intervention group (from 9.59% to 7.23%) and increased 2.03% (from 7.40% to 9.43%) in the control group; the difference was 4.39% (95% CI 3.48 to 5.30; P = 0.01). The boys in the intervention group had an effective reduction of −0.24 units in the change of BMI z-score (from 0.01 to −0.04), compared to control (from −0.10 to 0.09); 5.1% more intervention pupils undertook physical activity >5 hours/week than control pupils (P = 0.02). Fish consumption was a protector (odds ratio 0.39; 95% CI 0.23 to 0.67) while “fast-food” consumption was a risk factor for childhood obesity (odds ratio: 2.27; 95% CI 1.08 to 4.77). Conclusions Our school-based program, conducted by HPA students, successfully reduced childhood obesity prevalence in boys.

    Bovine viral diarrhoea virus (BVDV) is a major pathogen of cattle and is responsible for considerable reproductive loss. In this study, the in vivo responses in six multiparous cows were investigated after a non-cytopathogenic BVDV challenge (strain Pe 515; 5 x 10(6) tissue culture infective dose 50) given 9 days before a synchronized ovulation. Six similar cows challenged with non-infectious culture medium served as controls. The experimental noncytopathogenic BVDV infection was followed by a viraemia and leucopenia at days 5-9 after challenge, but no other clinical signs of infection were detected. However, the BVDV infection altered endocrine function. Mean LH pulse frequency immediately before CIDR withdrawal was lower (P < or = 0.05) in the BVDV-infected (2.17 +/- 0.34 pulses per 8 h) compared with the sham-infected (4.83 +/- 1.04 pulses per 8 h) animals. At day 3 after CIDR withdrawal, plasma oestradiol concentrations remained high (P < 0.05) in the infected cows (2.19 +/- 0.51 pg ml(-1)) compared with the sham-infected controls (0.72 +/- 0.29 pg ml(-1)). However, there was no difference in the peak oestradiol concentration (BVDV: 2.31 +/- 0.29 versus sham: 2.34 +/- 0.41 pg ml(-1)). In addition, non-cytopathogenic BVDV significantly (P < 0.05) increased the duration of the interval between ovulation and onset of the postovulatory progesterone increase (values 1.0 ng ml(-1)) (BVDV: 3.0 +/- 0.26 versus sham: 4.0 +/- 0.26 days). The viral infection also significantly (P < 0.01) decreased mean plasma progesterone concentrations between day 3 and day 11 after ovulation (BVDV: 2.59 +/- 0.32 versus sham: 4.13 +/- 0.27 ng ml(-1)). These data show that non-cytopathogenic BVDV viraemias during the follicular phase can modulate the secretion of gonadotrophins and sex steroids, in particular progesterone, during a synchronized oestrous cycle. Therefore, viraemias during the follicular phase may reduce the fertility of cattle by disrupting the capacity of the ovulatory

    Diarrhoeagenic Escherichia coli (DEC) represents a main group of enteric pathogens that cause human diarrhoea. Because it is not simply distinguished from normal flora by simple laboratory methods, modern molecular diagnostic assays are necessary. Although it is neither necessary nor applicable to perform PCR for all patients, it is of many advantages to verify the prevalence of DEC in different areas by this method. Knowing the prevalence of DEC in an area, we can focus on few pathogens and narrow our antimicrobial treatment. The aim of this study is to evaluate the contribution of the different DEC categories in children diarrhoea in the west of Iran.The stool specimens of 251 children with diarrhoea were collected from June to September 2007. Polymerase chain reaction (PCR) was performed to determine the presence of enteropathogenic (EPEC), enterotoxigenic (ETEC), entero-invasive (EIEC), Shiga toxin-producing (STEC) and entero-aggregative (EAEC) strains. ETEC strains were isolated from 13 and EAEC strains from 16 children. STEC was detected in 7 children, and no EIEC was isolated. Finally, EPEC strains were isolated in 41 cases. EAEC and EPEC are the most frequent DECs in children less than 10 years of age in West of Iran.

    Identifying the etiology of chronic diarrhoea might be challenging in some patients, and before a diagnosis is made these patients may spend a substantial length of time with unresolved symptoms leading to uncertainty and anxiety that is severely impairing their life quality. A 45-year-old female was referred by her general practitioner with a 5-year history of increasingly frequent episodes of cyclical diarrhoea, vomiting, abdominal pain and intermittent palpitations. Contrast CT Abdomen/Pelvis revealed a 36x33x46 mm mass in the aorto caval region of her retro-peritoneum, just above the bifurcation.  On the basis of her symptoms, CT findings and an elevated plasma metanephrine level of 2314pmol/L (normal range 80 – 510pmol/L), it was at this point a likely diagnosis of a phaeochromocytoma was made. The retroperitoneal mass was successfully resected, and the histology confirmed a Phaeochromocytoma. Her symptoms rapidly improved and she made a good recovery. This unusual case highlights some of the dilemmas that arise when investigating patients with chronic and recurrent diarrhoea and vomiting.

    In this study, the association between Eimeria spp. related signs and innate immune response in dairy calves was examined. Calves (n=100) aged 15-60 days were clinically examined and faecal samples, blood samples and deep nasopharyngeal swabs obtained. The samples were analysed for intestinal pathogens, acute phase proteins and WBC count, and respiratory tract pathogens, respectively. Diarrhoea was diagnosed in 32.6% (23.3-43.0%, 95% CI) of calves. An association between the pathogenic Eimeria spp. and diarrhoea was detected by multiple correspondence analysis. Eimeria related signs (diarrhoea, presence of pathogenic species and total oocyst count) were combined resulting a four level variable. Calves with weak signs of eimeriosis had decreased haptoglobin concentrations (p=0.02) and increased fibrinogen concentrations (p=0.048) compared to no signs. Increased haptoglobin and fibrinogen concentrations were associated with respiratory tract infection and umbilical infection. Serum amyloid A and WBC counts showed no association with signs of eimeriosis or clinical diagnoses.

    A geriatric patient status post intraabdominal surgery presented with persistent diarrhoea and heavy intestinal methicillin-resistant Staphylococcus aureus (MRSA) growth after multiple courses of antibiotic therapy. Additionally, swab cultures of the anterior nares tested positive for MRSA. In order to impede infection and prevent future complications, the patient received a 10-day course of vancomycin oral solution 250 mg every 6 h, 15-day course of Saccharomyces boulardii 250 mg orally twice daily and a 5-day course of topical mupirocin 2% twice daily intranasally. Diarrhoea ceased during therapy and repeat cultures 11 days after initiating therapy demonstrated negative MRSA growth from the stool and nares. Further repeat cultures 5 months later revealed negative MRSA growth in the stools and minimal MRSA growth in the nares. Overall, enteral vancomycin and probiotics successfully eradicated MRSA infection without intestinal recurrence. Although the results were beneficial treating MRSA diarrhoea for our patient, these agents remain highly controversial. PMID:22847566

    Background: Nifuroxazide is well known and often used anti-diarrhoeal medicine which has been pushed back from routine practice in recent years and often replaced with probiotics. Even probiotics are accepted and placed in some therapeutic guidelines for diarrhoea treatment, there are no enough evidence for its effectiveness and no comparative efficacy data with nifuroxazide in treatment of acute diarrhea. Patients and Methods: In open, prospective observational study, the efficacy and safety of nifuroxazide were compared with a probiotic containing lactic acid bacteria in the treatment of acute diarrhoea. A total number of 169 adult patients were included in this study, who administered nifuroxazide in the dose of 200 mg/4 times a day, while they took preparation containing lactic acid bacteria (1,2 x 107 live lyophilised lactic-acid bacteria) three times a day for three days. Results: Mean time to last unformed stool (TLUS) in a group which was treated with nifuroxazide was two days, while it took five days for the stool normalisation in the group using probiotic (p=0.0001). Conclusions: Orally administered nifuroxazide has demonstrated better efficiency as compared to probiotic in treating acute diarrhoea, and both medicines have shown the same safety and tolerance in this study.

    Six calves, aged 24 to 58 days and not previously exposed to bovine viral diarrhoea virus (BVDV), were infected with this agent by nose-to-nose contact with a persistently BVDV viraemic calf. The study was conducted in two trials, using 3 calves in each. All 6 calves showed a peak interferon level in serum at 4 days post infection (dpi), and they seroconverted to BVDV at 16-21 dpi. The calves in trial 1 had diarrhoea for 2 or 3 days between 2 and 6 dpi and one calf again from 9 to 11 dpi. During the periods of fever, the calves were slightly depressed. Those in trial 2 were more depressed and their oral and nasal mucous membranes were reddened but they never had diarrhoea. In both trials, fever (up to 41.3 degrees C) was a prominent symptom at 8 to 9 dpi and 2 calves showed a diphasic fever course. Respiratory affection was mild and no medical treatment was required. Haematological assessment demonstrated a transient but significant leukopenia and lymphopenia at 4 dpi (P less than 0.01 and P less than 0.05 respectively) and 11 dpi (P less than 0.05 and P less than 0.01 respectively). A significant decrease in thrombocyte count was seen at 4 dpi (P less than 0.05, n = 3). This study has demonstrated that nose-to-nose contact is an effective way of transmitting BVDV from persistently infected to susceptible cattle.

    To elucidate the pathophysiological changes leading to postantibiotic diarrhoea caused by Clostridium difficile and its cytotoxin, oral ampicillin was given to rabbits, and jejunal, ileal, and caecal segments of those that developed diarrhoea were investigated in vitro. The rabbits that, in response to treatment, harboured Clostridium difficile in their colonic lumen were studied, and the results expressed according to the presence or absence of Clostridium difficile and/or its cytotoxin. Thus, we refer to either CD+ or CD- segments. The influx of glucose, phenylalanine, glycylphenylalanine, and lysine across the brush border of jejunum and ileum of CD+ segments was severely impaired, while only slightly blunted in CD-. No significant change was detected in the influx of glutamic acid in the jejunum of all treated animals and in the CD- ilea. Morphologic damage in ileum and caecum of CD+ was also more evident than in CD-. Transepithelial ion transport across short circuited ileal mucosa (CD+ and CD-) revealed secretory changes in Cl net transport that were more marked in CD-. We conclude that: (1) Clostridium difficile may also colonise the upper intestinal tract, where it induces morphological and functional damage, severely impairing nutrient absorption; and (2) the ileum contributes to the diarrhoea caused by CD even when the micro-organism is confined to the more distal gut by showing moderate impairment of nutrient absorption and marked electrolyte secretion.

    Chronic diarrhoea is a common entity in daily clinical practice and it leads to a loss in these patients quality of life. It may be the main symptom of multiple ethiologies including bile acid malabsorption (BAM) which has a comparable prevalence to celiac disease. The BAM results from imbalances in the homeostasis of bile acids in the enterohepatic circulation. It can be a consequence of ileal disease or ileal dysfunction (BAM type i), it can be considered idiopathic or primary (BAM type ii) or associated with other gastrointestinal entities (BAM type iii). Among the different diagnostic methods available, (75)SeHCAT study is the primary current method due to its sensitivity, specificity, safety and low cost. The main disadvantage is that it's not available in all countries, so other diagnostic methods have appeared, such as serum measurement of FGF19 and C4, however they are significantly more complex and costly. The first-line treatment of bile acid diarrhoea is bile acid sequestrant, such as cholestyramine, which can be difficult to administer due to its poor tolerability and gastrointestinal side effects. These are less prominent with newer agents such as colesevelam. In summary, the BAM is a common entity underdiagnosed and undertreated, so it is essential to establish a diagnosis algorithm of chronic diarrhoea in which the (75)SeHCAT study would be first or second line in the differential diagnosis of these patients.

    Objectives Bile acid diarrhoea (BAD) is an underdiagnosed condition producing diarrhoea, urgency and fear of faecal incontinence. How patients experience these symptoms has not previously been studied. Bile Acid Malabsorption (BAM) Support UK was established in 2015 as a national charity with objectives including to provide details regarding how BAD affects patients, to improve earlier recognition and clinical management. Design, setting and main outcome A questionnaire was collected anonymously by BAM Support UK and the Bile Salt Malabsorption Facebook group over 4 weeks at the end of 2015. It comprised 56 questions and aimed to inform patients and clinicians about how BAD affects the respondents. Results The first 100 responses were analysed. 91% of the respondents reported a diagnosis of BAD. 58% of total respondents diagnosed following a Selenium-homocholic acid taurine scan, 69% were diagnosed by a gastroenterologist, with type 2 and 3 BAD comprising 38% and 37%, respectively, of total respondents. Symptoms had been experienced for more than 5 years before diagnosis in 44% of respondents. Following treatment, usually with bile acid sequestrants, 60% of participants reported improvement of diarrhoea and most reported their mental health has been positively impacted. Just over half of the cohort felt as though their symptoms had been dismissed during clinical consultations and 28% felt their GPs were unaware of BAD. Conclusions BAD requires more recognition by clinicians to address the current delays in diagnosis. Treatment improves physical and mental symptoms in the majority of participants. PMID:28123771

    Introduction: Smoke-free legislation has been a great success for tobacco control but its impact on smoking uptake remains under-explored. We investigated if trends in smoking uptake amongst adolescents differed before and after the introduction of smoke-free legislation in the United Kingdom. Methods: Prevalence estimates for regular smoking were obtained from representative school-based surveys for the four countries of the United Kingdom. Post-intervention status was represented using a dummy variable and to allow for a change in trend, the number of years since implementation was included. To estimate the association between smoke-free legislation and adolescent smoking, the percentage of regular smokers was modeled using linear regression adjusted for trends over time and country. All models were stratified by age (13 and 15 years) and sex. Results: For 15-year-old girls, the implementation of smoke-free legislation in the United Kingdom was associated with a 4.3% reduction in the prevalence of regular smoking (P = .029). In addition, regular smoking fell by an additional 1.5% per annum post-legislation in this group (P = .005). Among 13-year-old girls, there was a reduction of 2.8% in regular smoking (P = .051), with no evidence of a change in trend post-legislation. Smaller and nonsignificant reductions in regular smoking were observed for 15- and 13-year-old boys (P = .175 and P = .113, respectively). Conclusions: Smoke-free legislation may help reduce smoking uptake amongst teenagers, with stronger evidence for an association seen in females. Further research that analyses longitudinal data across more countries is required. Implications: Previous research has established that smoke-free legislation has led to many improvements in population health, including reductions in heart attack, stroke, and asthma. However, the impacts of smoke-free legislation on the rates of smoking amongst children have been less investigated. Analysis of repeated cross

    Acute diarrhoea in adults is one of the most commonly encountered medical emergency in general practice and is responsible for considerable morbidity around the world. To evaluate the efficacy and tolerability of fixed dose combination of ofloxacin with ornidazole infusion (infusion O2) in the management of diarrhoea and dysentery, a study was carried out among 290 patients, age group from 18 to 65 years suffering from diarrhoea, dysentery, gastro-enteritis. Study drug infusion O2, (Medley Pharmaceutical, Mumbai) containing ofloxacin 200 mg + ornidazole 500 mg was administrated twice daily for a duration of 5 days. Number of soft or watery stool, body temperature, nausea, abdominal pain, gas and flatulence were recorded at baseline and at the end of the study. Tolerability and efficacy was evaluated based on the global assessment by the investigator based on a 3-point scale marked as excellent/good/poor. Two hundred and fifty-six-patients (160 male and 96 female) were included for final analysis, 34 patients lost to follow-up. Mean number of watery stool per day was reduced from 9.273 +/- 0.4537 to 1.375 +/- 0.07001 (p < 0.0001) by infusion O2. Body temperature was significantly reduced from 38.055 +/- 0.045 degrees C to 36.778 +/- 0.016 degrees C (p < 0.0001) at the end of the study. Pretreatment symptom nausea was significantly reduced in 90.34% of patients. Improvement in vomiting symptoms was reported in 72.35% of patients after administration of anti-emetic drug; 96.84% and 77.25% of patients reported improvement in abdominal pain and gas/flatulence respectively at the end of the trial by infusion O2. As per investigators' assessment about efficacy of trial drug, 98.43% of patients reported good to excellent and 1.56% reported poor efficacy. As per investigators' assessment about tolerability 98.43% of patients reported good to excellent and 1.17% reported poor tolerability. Minor incidences of nausea, gastritis, metallic taste were reported in 7.42%, 7

  12. The Gambia and Bangladesh: the seasons and diarrhoea.

    PubMed

    Rowland, M G

    1986-09-01

    Climactic factors in the Gambia and Bangladesh have an important impact on the incidence of diarrheal disease. Both countries share some common characteristics in climate, including a cool dry winter of 3 months followed by a hot dry spring and hot wet summers of 5-7 months in length. The main difference is in the amount of rainfall. The Gambia may have 20-30 inches of rain each year; Bangladesh usually has up to 4-5 times this amount. In the Gambia, drought is a recurring problem; floods is the problem in Bangladesh. A study in the Gambia found a close link between the time of the annual peak in diarrhea in young children and the summer rains. A 2nd peak of diarrhea in the winter also was significant and was shown to coincide with a short period of intense transmission of rotavirus. Of the enteric infections of childhood, the enterotoxigenic "Escherichia coli" (ETEC), that is those producing heat-stable toxin (ST) were found to be the most important etiological agents of diarrhea in both countries, with a peak during the rains. In rural Gambia, water is obtained almost exclusively from surface wells, 15-20 meters deep. It was found that, although this water was fecally contaminated throughout the year, levels of contamination increased by up to 100 times with 1-2 days of the start of the rains because excreta is washed into the wells. It also was clear that contaminated water and domestic environment contribute to contamination of children's food. The high level of contamination of food during the summer coincided with the time of high diarrhea prevalence. In Bangladesh it was shown that the incidence of ETEC diarrhea in infants was positively correlated with the frequency of consumption of weaning foods contaminated with fecal coliforms. The seasonal peak of ETEC diarrhea coincided with the time when food was most contaminated due to higher bacterial growth caused by high temperatures. Cholera is endemic in many areas of Bangladesh but not in the Gambia. Though

    The study collected up-to-date data on prevalence and importance of Eimeria infections in Danish dairy calves with suspected clinical eimeriosis and analysed correlation between Eimeria spp., oocyst excretion and diarrhoea. From October 2010 through August 2011, veterinarians collected faecal samples from dairy herds (n = 52) with > 50 cows and a history of diarrhoea in young stock. Individual faecal samples were collected 3–4 weeks following re-housing to common pens from calves (n = 453) aged 3 weeks to 6 months. Faecal consistency and total number of oocysts per gram of faeces (opg) were determined, along with opg values for the specific Eimeria spp. Association between opg and faeces consistency was evaluated in a multinomial, logistic regression model. Overall prevalence of Eimeria spp. was 96.2 % with a prevalence of 60.9 % in individual calves. E. zuernii and/or E. bovis were detected in 88.5 % of the herds and 41.5 % of the calves. Mean opg was 2,040 (range 0–114,000) in the calves, of which 18.1 % had opg values ≥ 1,000. A total of 12 Eimeria spp. was found with the following calf prevalences: E. ellipsoidalis (37 %), E. zuernii (32 %), E. bovis (28 %), E. cylindrica (23 %), E. auburnensis (23 %), E. canadensis (10 %), E. subspherica (8 %), E. alabamensis (7 %), E. bukidnonensis (3 %), E. wyomingensis (1 %), E. pellita (0.2 %), E. brasiliensis (0.2 %). Mixed infections were present in all but one Eimeria-positive herds. Diarrhoea was seen in 35.9 % of the calves, and a significant (p = 0.003) positive correlation was detected between diarrhoea and total opg as well as diarrhoea and oocyst excretion for E. zuernii (p = 0.03), E. bovis (p = 0.05) and E. cylindrica (p = 0.04). No such relationship could be detected for E. ellipsoidalis (p = 0.87), E. subspherica (p = 0.54) or E. auburnensis (p = 0.10). Further studies should focus on possible synergistic effects of multiple Eimeria spp. infections as well as interaction between Eimeria spp. and other

    During a survey of foal diarrhoea between 1991 and 1994, Clostridium perfringens was significantly associated with disease with 56% of cases infected [1]. The contribution of enterotoxigenic C. perfringens to this association, was assessed by use of the reverse passive latex agglutination test for enterotoxin (RPLA; Oxoid Unipath) and vero cell toxicity neutralized by antitoxin on stored faecal samples and sporulated faecal isolates of C. perfringens. Polymerase chain reaction (PCR1) based on the DNA sequence for the whole enterotoxin gene [2] yielded a fragment from an equine isolate of the anticipated size which, cloned into plasmid M13 phage, had a sequence essentially identical to the published sequence. Consequently, all faecal isolates were also tested by PCR1 and for a part of the enterotoxin gene (PCR2). Significant association with diarrhoea (controls not in contact with cases) was found with positive RPLA tests on faeces (OR = 13, P = 0.002) and isolates (OR = 4.57, P = < 0.0001), vero cell toxicity of isolates (OR = 1.78, P = 0.026), and PCR1 (OR = nd, P = 0.029) but not PCR2 or vero cell toxicity of faeces. Significant association with diarrhoea was also found for isolates negative by RPLA (OR = 3.91; CI 2.05-7.57; P < 0.0001) or PCR1 (OR = 4.81; CI 2.84-8.20; P < 0.0001). Many of the isolates from RPLA positive faeces and verotoxic isolates were PCR negative and no evidence could be found for the presence of the enterotoxin gene in a random selection of RPLA positive/PCR negative isolates by gene probe on chromosomal DNA and PCR reaction product or vero cell toxicity neutralized by specific antiserum. Failure of the vero cell toxicity on faeces to be associated with diarrhoea or for cytotoxicity of cultures and RPLA on cultures to agree with the PCRs was believed to be related to the presence of other cytotoxins, the inherent cytotoxicity of equine faeces and to the poor specificity of the commercial antiserum used in the test.

    Dairy herds in Møre and Romsdal County, Norway (regarded as initially free from the bovine virus diarrhoea virus (BVDV) infection) were studied retrospectively from 1992 to 1996. The herd reproductive performance (time to first calving, calving interval, and number of breeding services) was investigated for a potential effect of BVDV sero-conversion. The herd culling pattern--possibly affecting the above measurements--was included for investigation. Two different statistical models were used: the generalised estimating equation (GEE) method and multilevel modelling using Gibbs sampling. Though slightly different estimates resulted, both models agreed on an effect of BVDV in the second year after sero-conversion on the herd average time to first calving by--on an average-- 14-16 days. In subsets of case herds testing positive for BVDV antibodies among young stock, the impact on time to first calving tended to be more pronounced by an additional increase of 18 days. No effect on the number of breeding services for heifers or cows was observed (indicating a need to search for other determinants than reduced conception risk). There appeared to be no effect of BVDV on the herd average calving interval. There was a tendency for a higher risk for reporting animals lost/died in sero-converted herds, which we believe might be related to the occurrence of mucosal disease.

  19. Phytochemicals from traditional medicinal plants used in the treatment of diarrhoea: modes of action and effects on intestinal function.

    PubMed

    2006-09-01

    Medicinal plants have been used as traditional treatments for numerous human diseases for thousands of years. Diarrhoeal diseases continue to be a major cause of morbidity and mortality throughout the world and there is renewed interest in the discovery of novel compounds that can be used to fight these diseases. Numerous studies have validated the traditional use of antidiarrhoeal medicinal plants by investigating the biological activity of extracts of such plants, which have antispasmodic effects, delay intestinal transit, suppress gut motility, stimulate water adsorption or reduce electrolyte secretion. Of the numerous phytochemicals (such as alkaloids, tannins, flavonoids and terpenes) present in active extracts, tannins and flavonoids are thought to be responsible for antidiarrhoeal activity by increasing colonic water and electrolyte reabsorption. Others act by inhibiting intestinal motility. As some of the active ingredients are potentially toxic, there is a need to evaluate the safety of plant preparations. A few clinical trials have evaluated the safety and tolerability of traditional and herbal medicine preparations used to treat diarrhoea and generally indicate that minimal side effects are observed. However, with the increased popularity of plant-derived and herbal medicines in Western society, the benefits and potential dangers of these medicines must be considered.

    2010-10-01

    A total of 17 typical and atypical enteropathogenic Escherichia coli (EPEC) were isolated from 396 children with and without diarrhoea. Out of 12 EPEC isolates from patients with diarrhoea, 3 (25 %) were atypical EPEC while 9 (75 %) were typical EPEC. It was observed that atypical EPEC strains had colonized the intestines of healthy children and its isolation rates were higher in healthy children than in children with diarrhoea. Interestingly all of the atypical EPEC isolates carried a megaplasmid, mostly comparable with the size of EPEC adherence factor (EAF) encoding gene but no virulence gene was detected in this megaplasmid. Studies also indicated that multidrug resistance EPEC are emerging and all the atypical EPEC strains showed significantly less resistance to all antimicrobial agents used in this study than typical EPEC. This study also supports the opinion that Shiga toxin-producing E. coli does not pose a major threat to human health in India. Subtyping analysis reveals that eae-α1, eae-β2 and eae-λ could be common EPEC subtypes prevalent in children with diarrhoea in Delhi. The present study is believed to be the first report of the detection of atypical EPEC from children without diarrhoea and records of isolation of eae-γ1, eae-γ2 and the rare eae-λ subtype in India. The data also indicated that typical EPEC are a common cause of diarrhoea and atypical EPEC are emerging as colonizers of the intestine of children with and without diarrhoea in Delhi and the National Capital Region, India.

The study used climatic and aggregated surveillance diarrhoea incidence data of two peak periods of seven months each over two consecutive years. A Poisson regression model and a lagged Poisson model with autocorrelation was performed to test the relationship between climatic parameters (minimum and maximum temperature) and incidence of diarrhoea. In total, 58,617 cases of diarrhoea occurred in the CTMA, which is equivalent to 8.60 cases per 100 population under five years old for the study period. The mixed effect overdispersed Poisson model showed that a cluster adjusted effect of an increase of 5 °C in minimum and maximum temperature results in a 40% (Incidence risk ratio IRR: 1.39, 95% CI 1.31–1.48) and 32% (IRR: 1.32, 95% CI: 1.22–1.41) increase in incident cases of diarrhoea, respectively, for the two periods studied. Autocorrelation of one-week lag (Autocorrelation AC 1) indicated that a 5 °C increase in minimum and maximum temperature led to 15% (IRR: 1.46, 95% CI: 1.09–1.20) and 6% (IRR: 1.06, 95% CI: 1.01–1.12) increase in diarrhoea cases, respectively. In conclusion, there was an association between an increase in minimum and maximum temperature, and the rate at which diarrhoea affected children under the age of five years old in the Cape Town Metropolitan Area. This finding may have implications for the effects of global warming and requires further investigation. PMID:27589772

    Background The original version of the Childhood Health Assessment Questionnaire (CHAQ30orig) suffers from a ceiling effect and hence has reduced clinical validity. The purpose of this study was to evaluate the effect of adding eight more demanding items (CHAQ38) and a new categorical response option (CATII) on discriminant validity and score distribution in a European patient sample. Methods Eighty-nine children with Juvenile Idiopathic arthritis (JIA) and 22 healthy controls, aged 7-16 years, were recruited from eight centres across Europe. Eight new CHAQ items and scoring option were translated back and forth for the countries in which they were not already present. Demographic, clinical, and CHAQ data were collected on-site. Subsequently, five different scoring methods were applied, i.e. the original method (CHAQ30orig) and four alternatives. These alternatives consisted of the mean item scores for the 30 and 38-question versions with either the original (CATI), or the new categorical response option (CATII). The five versions were tested for their ability to distinguish between patients and controls. Furthermore score distributions were evaluated and visualized by box and whisker plots. Results Two CHAQ revisions with the new response option showed poor discriminative ability, whereas one revised version (CHAQ38CATI) had comparable discriminative ability comparable to the original CHAQ. A profound ceiling effect was observed in the original scoring method of the CHAQ (27%). The addition of eight more demanding items and application of a plain mean item score reduced this significantly to 14% (χ2 = 4.21; p < 0.05). Conclusions Revising the CHAQ by adding eight more demanding items and applying a plain mean item scoring (CHAQ38CATI) maintained discriminant ability and reduced the ceiling effect in a European patient sample. The new categorical response option (CATII) seemed promising, but was less able to distinguish children with JIA from healthy controls and

    Probiotic could be a promising alternative to antibiotics for the prevention of enteric infections; however, further information on the dose effects is required. In this study, weanling piglets were orally administered low- or high-dose Lactobacillus rhamnosus ACTT 7469 (10(10) CFU/d or 10(12) CFU/d) for 1 week before F4 (K88)-positive Escherichia coli challenge. The compositions of faecal and gastrointestinal microbiota were recorded; gene expression in the intestines was assessed by real-time PCR; serum tumour necrosis factor-α (TNF-α) concentrations and intestinal Toll-like receptor 4 (TLR4) were detected by ELISA and immunohistochemistry, respectively. Unexpectedly, high-dose administration increased the incidence of diarrhoea before F4(+)ETEC challenge, despite the fact that both doses ameliorated F4(+)ETEC-induced diarrhoea with increased Lactobacillus and Bifidobacterium counts accompanied by reduced coliform shedding in faeces. Interestingly, L. rhamnosus administration reduced Lactobacillus and Bifidobacterium counts in the colonic contents, and the high-dose piglets also had lower Lactobacillius and Bacteroides counts in the ileal contents. An increase in the concentration of serum TNF-α induced by F4(+)ETEC was observed, but the increase was delayed by L. rhamnosus. In piglets exposed to F4(+)ETEC, jejunal TLR4 expression increased at the mRNA and protein levels, while jejunal interleukin (IL)-8 and ileal porcine β-defensins 2 (pBD2) mRNA expression increased; however, these increases were attenuated by administration of L. rhamnosus. Notably, expression of jejunal TLR2, ileal TLR9, Nod-like receptor NOD1 and TNF-α mRNA was upregulated in the low-dose piglets after F4(+)ETEC challenge, but not in the high-dose piglets. These findings indicate that pretreatment with a low dose of L. rhamnosus might be more effective than a high dose at ameliorating diarrhoea. There is a risk that high-dose L. rhamnosus pretreatment may negate the preventative effects

    In Bangladesh diarrhea occurs most often in children between the ages of 6-11 months. Crawling infants in rural areas come into contact with chicken feces and other animal dung on the ground both inside and outside the home. Additionally, the ground is contaminated with the baby's own feces and those of its brothers and sisters. Many infants put earth and feces in their mouths and most suck their fingers, which have touched and will pass on germs and fecal matter. Infants in 2 villages near Dhaka were found to have high rates of illness and malnutrition. Those whose families were poor and did not own land were affected more severely; they had worse malnutrition and a higher incidence of diarrhea. In both villages most infants were put down to play for most of the day. Most mothers said they rarely or never put a mat or jute sack down for their baby to lie on or crawl around on, and only a third of mothers were able to watch their babies continuously. The ground on which these infants were crawling was found to be highly contaminated. It was learned that while most mothers knew that feces were dirty, they were unaware that feces can cause disease. Poor traditional weaning practices and poor food hygiene also contributed to high attack rates of diarrhea. Basic messages and a range of interventions to improve traditional hygiene and health care practices were developed. First, mothers need to understand about germs and the fact that these cause diseases. Local materials and ideas were used to demonstrate this to a mainly illiterate audience. Interventions to keep the baby from touching and eating feces include: sweeping the baby's play area 4 times a day; using a dirt disposer, like a trowel, to remove feces from the ground; using a covered pit or latrine to dispose of feces; using a special place for disposing of garbage; and keeping crawling infants in a playpen. Interventions to reduce transmission of germs include: washing hands with ashes or soap after defecating

    Background Globally, about seven million children under the age of five died in 2011. Local illness concepts are thought to be related to inappropriate health-seeking behaviour, and therefore, lead to child mortality. The aim of this study was to contribute to the definition of common local illness concepts with their effects on health-seeking behaviour for common childhood illnesses. Methods A qualitative focus group study was conducted between April 1 and 6, 2013. Participants were drawn purposefully from the vaccination unit at Shuhair Health Centre in Yemen. Four focus group discussions were conducted. The total number of participants was 31 mothers with at least one child under the age of five with a history of fever, diarrhoea, cough, or difficulty breathing during the 14 days preceding the study. Data was collected and analysed using micro-interlocutor analysis. Results The mean age of the participants was 31 years (SD ± 4). There was remarkable concordance in local illness concepts across the focus groups. During focus group discussions, six local illness concepts (Senoon, lafkha, halib, didan, raqaba, and ayn) were mentioned. Local illness concepts determined the type of treatment. Most of these illnesses were not treated medically. Lafkha, halib, raqaba, and ayn were always classified as “not for medical treatment”, whereas senoon and didan as sometimes “not for medical treatment”. For medical symptoms, i.e. fever, diarrhoea, cough, and difficulty breathing, medical therapy was usually an option; these were classified as never or sometimes “not for medical treatment”. Mothers trust in traditional medicine and believe that it is always beneficial and never harmful. The participants do not disclose traditional medicine use with their doctors because doctors oppose these practices and are not open enough to these types of treatment. Conclusions Local illness concepts for common child illnesses are widespread, and they determine the type of

    The economic impact of BVDV infections has led a number of countries in Europe to start eradication or control programmes. While in both cases the primary step is identification and elimination of persistently infected (PI) animals, the strategy applied thereafter is dependent on the density and seroprevalence of the regional cattle population. One of the first countries to design and implement an eradication programme was Sweden in 1993, a country with a relatively low cattle density and no vaccination. For screening, an indirect antibody ELISA for serum, milk and bulk milk samples is being used. The basics of the Swedish model are no vaccination, voluntary participation, and financing of the entire scheme by the subscribing farmers. BVDV-free herds are certified and permanently checked. While in 1993 only about 35% of the herds were seronegative, about 87% were BVDV-free in 2001. The aim of control programmes in high density areas with high seroprevalence is to minimize economic losses by reducing the incidence of PI animals and thereby virus circulation (German model). Participation is voluntary, and parts of the costs are carried by the public animal insurance (Tierseuchenkasse). Screening is performed using an antigen capture ELISA with blood or serum. In Lower Saxony, for example, a herd is declared BVDV unsuspicious if all animals up to 36 months are BVDV antigen negative and the female offspring older than six months is vaccinated twice (an inactivated vaccine is used for basic immunization, and an attenuated live virus vaccine for boosting).

    OBJECTIVE—Evaluation of nutritional recovery, intestinal permeability, and insulin-like growth factor I (IGF-I) response in malnourished children with persistent diarrhoea and their relation to concomitant systemic infection(s).
STUDY DESIGN—Open study of severely malnourished children (aged 6-36 months) with persistent diarrhoea (⩾ 14 days) admitted for nutritional rehabilitation with a standardised rice-lentil and yogurt diet. Successful recovery was defined prospectively as overall weight gain (> 5 g/kg/day) with a reduction in stool output by day 7of treatment. Data on coexisting infections and serum C reactive protein (CRP) were collected at admission.
RESULTS—Of 63 children, 48 (group A) recovered within seven days of dietary treatment. These children had a significant increase in serum IGF-I (ΔIGF-I%) and, in contrast to serum prealbumin and retinol binding protein, ΔIGF-I% correlated with weight gain (r = 0.41). There was no correlation between the IGF-I response and intestinal permeability as assessed by urinary lactulose/rhamnose excretion. Treatment failures (group B) included more children with clinical (relative risk, 4.8; 95% confidence interval, 1.2to 19.7) and culture proven sepsis at admission and higher concentrations of serum CRP (median (range), 36 (0−182) v 10 (0−240) mg/l) at admission. There was a negative correlation between admission CRP concentration and ΔIGF-I% (r = −0.45).
CONCLUSIONS—In comparison with serum albumin, prealbumin, and retinol binding protein, serum IGF-I increment is a better marker of nutritional recovery in malnourished children with persistent diarrhoea. The possible association of systemic infections, serum IGF-I response, and mucosal recovery needs evaluation in future studies.

    In Bangladesh, the burden of diarrheal diseases is significant among children <5 years old. The objective of this study is to capture the prevalence of and health care–seeking behavior for childhood diarrheal diseases (CDDs) and to identify the factors associated with CDDs at a population level in Bangladesh. We use a logistic regression approach to model careseeking based on individual characteristics. The overall diarrhea prevalence among children <5 years old was found to be 5.71%. Some factors found to significantly influence the health care–seeking pattern were age and sex of the children, nutritional score, age and education of mothers, wealth index, and access to electronic media. The health care service could be improved through working in partnership with public facilities, private health care practitioners, and community-based organizations, so that all strata of the population get equitable access in cases of childhood diarrhoea.

    Oral rehydration salt (ORS) treatment in young children with acute diarrhoea (AD) has contributed to decrease mortality associated with dehydration although effective strategies to reduce morbidity associated with this disease are required. The aim of this study was to evaluate the diarrhoea duration when using combined colloidal bismuth hydroxide gel (CBHG) and oral rehydration salt treatment compared with ORS therapy in children with AD. We designed a double-blind, randomised prospective study with treatment and control groups. Patients aged one to 12 years, with no prior pathology and with AD of less than 48 h were included. The Chi-squared and Mann-Whitney tests were used, as well as the Cox proportional hazards model and the Kaplan-Meier estimator. Patients were randomised into an ORS and CBHG treatment group and a control group for ORS plus placebo. (Average age: 3.2 years). The result of the post-treatment evaluation with respect to the average duration of AD was 25.5 h for the treated group vs. 41.5 h for the control group (p = 0.015). The average number of stools was 4.8 in the treated group and 8.2 in the control group (p = 0.032). We conclude that the use of CBHG plus ORS significantly reduced the duration of AD, the number of stools and the percentage of children with persistent AD after 24 h of treatment compared to the control group. AD remitted almost twice as fast in patients treated with CBHG and ORS compared to those who received ORS plus placebo. PMID:28009823

  11. Risk factors and epidemiological characteristics of new neonatal porcine diarrhoea syndrome in four Danish herds

    PubMed Central

    2014-01-01

    Background The epidemiology of New Neonatal Porcine Diarrhoea Syndrome (NNPDS) was studied in four selected herds. A total of 941 new born piglets in 86 litters were evaluated for five consecutive days. NNPDS is a newly emerged syndrome, characterized by diarrhoea within the first week of life, which is un-responsive to antibiotics and not associated with known pathogens. The aetiology behind the syndrome is unknown, and specific risk factors predisposing piglets to develop NNPDS also remain to be determined. The study evaluated sow and piglet-level risk factors for developing NNPDS and described the epidemiologic characteristics within four herds previously diagnosed with the syndrome. NNPDS was defined as diarrhoea at any time-point during the second to fifth day of life. Results NNPDS was observed in a total of 60% (range: 39%-89%) of first parity piglets and 36% (range: 19-65%) of piglets born by mature sows. In total of 26% of piglets had liquid faeces on the day of birth. Approximately half of these piglets developed NNPDS. In the majority of cases (50-70% of cases within herds) symptoms started on the second or third day of life. Piglets in Herd 1 had12.8 times higher probability of developing NNPDS than piglets in Herd 4. First parity piglets had a 4.1 higher probability of developing NNPDS than piglets born by mature sows. Birth weight and faecal consistency on the day of birth were minor risk factors, each significant within one herd. Conclusions The most important factors associated with NNPDS were herd of origin and sow-parity. The reason for one of the herds experiencing a considerably more severe outbreak than the others was not explained by factors addressed in this study. The epidemiological pattern of diarrhoea varied a lot between herds; however, in all herds first parity piglets seemed predisposed. This association may be explained by an infectious background of the syndrome, but further studies are needed to explain this association. PMID

  12. Newer insights into the mechanism of action of Psidium guajava L. leaves in infectious diarrhoea

    2010-01-01

    Background Psidium guajava L., Myrtaceae, is used widely in traditional medicine for the treatment of diarrhoea, dysentery, gastroenteritis, stomachaches, and indigestion. However, the effect of the leaf extract of P. guajava on the pathogenesis of infectious diarrhoea has not been studied. The present study evaluates the effect of a hot aqueous extract (decoction) of dried leaves of P. guajava on parameters associated with pathogenicity of infectious diarrhoea. The aim was to understand its possible mechanism(s) of action in controlling infectious diarrhoea and compare it with quercetin, one of the most reported active constituents of P. guajava with antidiarrhoeal activity. Methods The crude decoction and quercetin were studied for their antibacterial activity and effect on virulence features of common diarrhoeal pathogens viz. colonization of epithelial cells and production and action of enterotoxins. Colonization as measured by adherence of enteropathogenic Escherichia coli (EPEC) and invasion of enteroinvasive E. coli (EIEC) and Shigella flexneri was assessed using HEp-2 cell line. The production of E. coli heat labile toxin (LT) and cholera toxin (CT) and their binding to ganglioside monosialic acid (GM1) were studied by GM1-ELISA whereas the production and action of E. coli heat stable toxin (ST) was assessed by suckling mouse assay. Results The decoction of P. guajava showed antibacterial activity towards S. flexneri and Vibrio cholerae. It decreased production of both LT and CT and their binding to GM1. However, it had no effect on production and action of ST. The decoction also inhibited the adherence of EPEC and invasion by both EIEC and S. flexneri to HEp-2 cells. Quercetin, on the other hand, had no antibacterial activity at the concentrations used nor did it affect any of the enterotoxins. Although it did not affect adherence of EPEC, it inhibited the invasion of both EIEC and S. flexneri to HEp-2 cells. Conclusion Collectively, the results indicate

    This report describes the first identification in Poland of bovine viral diarrhoea virus (BVDV)-2 in a dairy herd where severe clinical disease with losses of young animals was observed. The virus was readily cultivated in cell culture and a phylogenetic analysis of the nucleotide sequences and secondary structures of the viral genomic 5' untranslated region confirmed virus identity. The economic impact of the infection was significant compared to the previously prevalent BVDV-1 infections confirming that this genotype of BVDV can cause severe sickness in affected herds. The use of BVDV-1 vaccine did not prevent the infection with the BVDV-2 genotype.

    Design Prospective cohort study. Setting Teaching paediatric hospital—Instituto de Medicina Integral Prof. Fernando Figueira (IMIP), Recife, Northeast Brazil. Participants 378 of 536 infants admitted in paediatric wards from April to October 2009 were daily assessed during hospital stay until the first episode of nosocomial diarrhoea (ND), death or discharge. Infants with community-acquired diarrhoea, respiratory or haemodynamic instability and who stayed in hospital for <24 h were excluded. Primary and secondary outcome measures Incidence and risk factors for ND and rates of pacifier faecal contamination. Results 33 ND episodes occurred in 378 infants, with a cumulative incidence of 8.7% and density of 11.25/1000 patients-day. ND occurred in 8.2% (16/194) of pacifier users compared with 9.2% (17/184) in non-users (adjusted OR=0.88, 95% CI 0.43 to 1.80). In multivariate logistic regression analysis, duration of oxygen use (OR=1.61; 95% CI 1.18 to 2.20) and days of antimicrobial use (OR=1.62, 95% CI 1.34 to 1.94) were associated with higher risk of ND, whereas being breast fed (OR=0.40, 95% CI 0.17 to 0.93) and each day of hospital stay (OR=0.65, 95% CI 0.53 to 0.80) were protective factors. Faecal coliforms were isolated in 16% (27/169) of tested pacifiers, 77.8% of which had more than 100 000 CFU/ml. The probability of a child remaining free of an episode of diarrhoea up to the seventh day of hospitalisation in the ward was 91.2% (95% CI 87.7% to 94.9%). The log-rank test showed no statistical difference between pacifier users and non-users. Conclusions ND is a frequent healthcare-associated infection in paediatric wards, but the use of pacifiers during the stay in hospital does not seem to affect the incidence of ND in infants in many settings where the burden of diarrhoea is still high.

    Asthma prevalence in children has increased 58% since 1980. Mortality has increased by 78%. The burden of the disease is most acute in urban areas and racial/ethnic minority populations. Hospitalization and morbidity rates for nonwhites are more than twice those for whites. Asthma is characterized by recurrent wheezing, breathlessness, chest tightness, and coughing. Research in the past decade has revealed the importance of inflammation of the airways in asthma and clinical treatment to reduce chronic inflammation. Asthma is associated with production of IgE to common environmental allergens including house dust mite, animal dander, cockroach, fungal spores, and pollens. Some interventions to reduce symptoms through control of dust mite and animal dander have had positive results. Control of symptoms through interventions to reduce exposures to cockroach antigen has not been reported. Studies illustrating causal effects between outdoor air pollution and asthma prevalence are scant. Increases in asthma prevalence have occurred at the same time as general improvements in air quality. However, air quality appears to exacerbate symptoms in the child who already has the disease. Decreased pulmonary function has been associated with exposure to particulates and bronchial hyperresponsiveness to smoke, SO(2) and NO(2). Symptoms have been correlated with increased levels of respirable particulates, ozone, and SO(2). Interventions that reduce the negative outcomes in asthma associated with outdoor environmental factors have not been reported. Control of asthma in children will entail the collaborative efforts of patients, family, clinical professionals, and school personnel, as well as community-wide environmental control measures and conducive national and local policies based on sound research.

    Early-life microbial exposure is of particular importance to growth, immune system development and long-lasting health. Hence, early microbiota composition is a promising predictive biomarker for health and disease but still remains poorly characterized in regards to susceptibility to diarrhoea. In the present study, we aimed to assess if gut bacterial community diversity and composition during the suckling period were associated with differences in susceptibility of pigs to post-weaning diarrhoea. Twenty piglets from 5 sows (4 piglets / litter) were weaned in poor housing conditions to challenge their susceptibility to post-weaning diarrhoea. Two weeks after weaning, 13 pigs exhibited liquid faeces during 2 or 3 days and were defined as diarrhoeic (D) pigs. The other 7 pigs did not have diarrhea during the whole post-weaning experimental periodand were defined as healthy (H) pigs. Using a molecular characterisation of fecal microbiota with CE-SSCP fingerprint, Next Generation Sequencing and qPCR, we show that D and H pigs were mainly discriminated as early as postnatal day (PND) 7, i.e. 4 weeks before post-weaning diarrhoea occurence. At PND 7 H pigs displayed a lower evenness and a higher abundance of Prevotellaceae, Lachnospiraceae, Ruminocacaceae and Lactobacillaceae compared to D pigs. The sPLS regression method indicates that these bacterial families were strongly correlated to a higher Bacteroidetes abundance observed in PND 30 H pigs one week before diarrhoea. These results emphasize the potential of early microbiota diversity and composition as being an indicator of susceptibility to post-weaning diarrhoea. Furthermore, they support the health promoting strategies of pig herds through gut microbiota engineering.

The other 7 pigs did not have diarrhea during the whole post-weaning experimental periodand were defined as healthy (H) pigs. Using a molecular characterisation of fecal microbiota with CE-SSCP fingerprint, Next Generation Sequencing and qPCR, we show that D and H pigs were mainly discriminated as early as postnatal day (PND) 7, i.e. 4 weeks before post-weaning diarrhoea occurence. At PND 7 H pigs displayed a lower evenness and a higher abundance of Prevotellaceae, Lachnospiraceae, Ruminocacaceae and Lactobacillaceae compared to D pigs. The sPLS regression method indicates that these bacterial families were strongly correlated to a higher Bacteroidetes abundance observed in PND 30 H pigs one week before diarrhoea. These results emphasize the potential of early microbiota diversity and composition as being an indicator of susceptibility to post-weaning diarrhoea. Furthermore, they support the health promoting strategies of pig herds through gut microbiota engineering. PMID:28072880

    A 45-year-old-Haitian male patient with fever, abdominal cramping, chronic diarrhoea and weight loss of about 3 kg was investigated. Stool examination revealed Salmonella typhi and Cyclospora cayetanensis. The HIV test was positive with a CD4 count of 130 cells/mm(3). We provided the first report of co-infection Cyclospora cayetanensis and Salmonella typhi in a HIV patient with chronic diarrhoea. The patient was treated with oral ciprofloxacin, 500 mg, twice daily for two weeks, with a good clinical outcome.

    In this study the importance of Providencia species as a cause of travellers' diarrhoea was examined using a selective medium developed by the authors. Providencia species could easily be distinguished from other enteric pathogens by the colour of the colonies obtained. Nine strains of Providencia alcalifaciens, nine of Providencia rettgeri and five of Providencia stuartii were isolated from 130 specimens, representing a surprisingly high incidence of infection compared with other pathogens isolated on SS agar and TCBS agar. Patients infected with P. rettgeri complained of abdominal pain, as for other Providencia species, but also of vomiting, which is rather characteristic of P. rettgeri infection. To analyse the pathogenicity of these isolates, their invasiveness was examined using Caco-2 cells. Most of the P. rettgeri strains invaded Caco-2 cells. Random amplified polymorphic DNA (RAPD) fingerprinting showed the same profile for two P. rettgeri isolates from individuals travelling in the same tour group. The results show that Providencia species, especially P. rettgeri, might cause diarrhoea, and that these species are important pathogens.

    An observational study of patients presenting with diarrhoea to a walk-in service for returning travellers was conducted with the aim of identifying features that would help predict whether pathogens were bacterial or parasitic. In total, 509 cases were included, of which a bacterial aetiology was found in 55/440 (12.5%) and a parasitic cause in 51/428 (11.9%). Patients with symptoms of ≤14 days were significantly more likely to have a bacterial diagnosis than those with longer symptoms (p<0.001), whereas parasitic causes of diarrhoea were not associated with length of symptoms and became proportionately more likely with time. Raised CRP, faecal white cells and fever were all predictive of positive bacterial culture (p<0.001, p=0.001 and p=0.001, respectively) but did not predict parasitic infection. Travellers to South and Southeast Asia were more likely to have parasites detected in their stool than travellers to other tropical areas (OR=1.96; p=0.041). Gender, ethnicity, reason for travel and length of stay abroad were not significantly associated with the faecal pathogen identified. These findings should help guide appropriate antimicrobials when empirical therapy is indicated.

  4. The discovery of cholera - like enterotoxins produced by Escherichia coli causing secretory diarrhoea in humans

    Non-vibrio cholera has been recognized as a clinical entity for as long as cholera was known to be caused by Vibrio cholerae. Until 1968, the aetiologic agent of this syndrome was not known. Following a series of studies in patients with non-vibrio cholera it was found that these patients had large concentrations of Escherichia coli in the small bowel and stools which produced cholera toxin-like enterotoxins, and had fluid and electrolyte transport abnormalities in the small bowel similar to patients with documented cholera. Furthermore, these patients developed antibodies to the cholera-like enterotoxin. Later studies showed that these strains, when fed to volunteers produced a cholera-like disease and that two enterotoxins were found to be produced by these organisms: a heat-labile enterotoxin (LT) which is nearly identical to cholera toxin, and a heat-stable enterotoxin (ST), a small molecular weight polypeptide. E. coli that produced one or both of these enterotoxins were designated enterotoxigenic E. coli (ETEC). ETEC are now known not only to cause a severe cholera-like illness, but to be the most common bacterial cause of acute diarrhoea in children in the developing world, and to be the most common cause of travellers’ diarrhoea in persons who visit the developing world.

    Diarrhoea continues to be one of the most common causes of morbidity and mortality among infants and children in developing countries. To investigate the incidence, antimicrobial resistance and genetic relationships of enteropathogenic Escherichia coli (EPEC) in children with diarrhoea, a total of 612 stool specimens were collected in Tehran, Iran, and cultured to isolate strains of EPEC. The disc diffusion method was used to determine the susceptibility of the isolates according to the Clinical and Laboratory Standards Institute (CLSI) guidelines. The presence of eae, stx and bfp-A genes was determined by PCR. The genetic relationships between EPEC isolates were determined by pulsed-field gel electrophoresis (PFGE). Out of the 412 strains of E. coli obtained from 612 diarrhoeal stool specimens, 23 (5.6 %) were identified as EPEC, of which seven (30.4 %) were classified as typical strains of EPEC and 16 (69.6 %) were classified as atypical. Out of the 23 EPEC isolates, 69.5 % were resistant to ampicillin, 39.1 % were resistant to tetracycline and cotrimoxazole, 30.4 % were resistant to cefpodoxime, ceftazidime, ceftriaxone and aztreonam, and 26.1 % were resistant to imipenem. The isolates were classified into 21 pulsotypes by PFGE profiles. The present study shows that typical and atypical EPEC isolates displayed considerable heterogeneity in PFGE profiles and EPEC infections were only sporadic in Tehran. Overall 69 % of isolates were resistant to at least one of the antibiotics tested.

  6. Infectious diarrhoea in children: controlling transmission in the child care setting.

    PubMed

    Thompson, S C

    1994-06-01

    An increase in the number of preschool children cared for within groups in child care centres has been associated with increasing numbers of women in the workforce. Children at this age are at high risk for gastrointestinal diseases caused by a large number of enteric pathogens, and the risk is increased by the greater potential for person-to-person transmission within group care. This report considers the pathogens that may cause diarrhoeal illness in children, with particular reference to those that have been reported in formal day care settings. The major risk factors for transmission of these agents and a high rate of diarrhoeal illness in the child care setting include attendance of non-toilet-trained children, staff combining nappy changing and food preparation duties, large enrollment, low staff-to-child ratio, and poor hygiene and child handling practices. Investigations undertaken during an outbreak of diarrhoea have frequently used limited diagnostic testing, often suitable for identifying only bacterial and protozoal agents. Such limited investigations have tended to incriminate agents that have prolonged carriage and are easily identifiable in standard microbiology laboratories. Finding a pathogen in these circumstances needs to be interpreted with caution. Prevention and control measures include training and education in good personal hygiene, emphasis on the need for frequent handwashing, separation of change areas from food handling and eating areas, routine cleaning and disinfection of environmental surfaces and personal items, and exclusion of any child or child care worker with diarrhoea.

    The aim of this investigation was to evaluate the effects of a structured exercise programme in sedentary dogs with chronic diarrhoea. Twenty-two dogs were enrolled in the study. All dogs received oral prednisolone (1 mg/kg/day for 14 days, followed by a tapering dosage) for 10 weeks. After four weeks of prednisolone treatment, dogs were assigned to either the exercise or control group (n=11 each). Owners of dogs in the exercise group were instructed to guide their dogs in structured exercise training (low-intensity to moderate-intensity aerobic and resistance exercise three to five days per week). After 10 weeks of prednisolone treatment with concomitant 6 weeks of complementary exercise, the Canine Inflammatory Bowel Disease Activity Index (CIBDAI) score had decreased significantly in the exercise group (from 8.8±1.5 at the start of the exercise programme to 2.4±1.5; P<0.001); no such change was observed in the control group (from 9.2±0.9 to 9.2±1.1). CIBDAI scores differed significantly between the groups at the end of the 10-week study period (P<0.001). The exercise programme affected all six CIBDAI parameters significantly; bodyweight (P<0.001, adjusted r(2)=0.722) was most affected. A structured exercise programme may have positive effects on clinical symptoms in sedentary dogs with chronic diarrhoea.

    Childhood vitiligo differs from the adults by showing a higher incidence in females, segmental vitiligo being more common and less frequent association with other systemic autoimmune and endocrine disorders. Childhood vitiligo is often associated with a marked psychosocial and long lasting effect on the self-esteem of the affected children and their parents, hence an adequate treatment is very essential. Treatment of vitiligo is indeed a tough challenge for the dermatologists’ more so in the background of childhood vitiligo. Although multiple therapeutic modalities are available in the therapeutic armamentarium, not all can be used in children.

    Several data from different authors show that Bovine virus diarrhoea virus (BVDV) could be a key component in multiple-etiology diseases, indeed a lower leukocytes number and their impaired functions decrease the resistance to infections. However, most of the information on the impairment of immune function during BVDV infections arise from circumstantial evidence and from experimental infection studies, and few from field data. To assess the effects of BVDV on blood cells parameters, cellular and humoral functions under field conditions, we designed a controlled study in commercial dairy herds, comparing persistent infected (PI) and healthy heifers. A total of 45 heifers were considered, the PI animals were nine, the control animals were 34, while two controls were considered as acute infected animals. The comparison of the mean values in PI calves showed a significant decrease for leukocytes and granulocytes, while platelets showed a significant increase, when compared with control animals. The total number of lymphocytes decreased not significantly in PI animals, while the proportion significantly increased. The number and proportion of monocytes was significantly reduced in PI animals, when compared with controls. The data collected on markers of cellular immunity during our study cannot be compared with the literature because there are no reference values. The presence of a persistent infection affected the cellular enzymes: NAGase, lysozyme and respiratory burst showed a large statistically significant decrease in PI animals when compared with controls. The presence of a persistent infection with BVD virus influenced blood cells number and impaired some blood cell functions. Such impairment confirms that PI animals represent a threat to the herd not only because they could spread BVDV, but also because they are more susceptible to other infectious diseases.

    Bovine viral-diarrhoea (BVD), enzootic bovine leukosis (EBL), Johne's disease (JD), and neosporosis lower on-farm productivity, reduce export competitiveness, and increase consumer concerns regarding safety. Our purpose was to examine the relationship between 27 control practices and the estimated true seroprevalences for these four diseases for 2604 cattle in 90 dairy herds in the Maritimes provinces of Canada. Overall, 37.8, 20.4, 3.4, and 19.2% of all sampled cattle were truly exposed to the agents of BVD, EBL, JD, and neosporosis, respectively. The median within-herd true prevalences were 0, 9.3, 0, and 12.3%, respectively. Factor analysis reduced the 27 control practices to two highly correlated factors. Tobit-regression analyses determined that vaccination practices were associated with reduced prevalence of exposure for Bovine viral-diarrhoea and EBL. Also, farms that tended to purchase their dairy animals were associated with higher seroprevalence for Johnes' disease. Neither of these two factors was associated with the seroprevalence of Neospora caninum infection. The few routine biosecurity measures that were investigated in this study were generally not related to the seroprevalences of these farms.

    Cholera is an important public health problem in Bangladesh. Interventions to prevent cholera depend on their cost-effectiveness which in turn depends on cholera incidence. Hospital-based diarrhoeal disease surveillance has been ongoing in six Bangladeshi hospitals where a systematic proportion of patients admitted with diarrhoea were enrolled and tested for Vibrio cholerae. However, incidence calculation using only hospital data underestimates the real disease burden because many ill persons seek treatment elsewhere. We conducted a healthcare utilization survey in the catchment areas of surveillance hospitals to estimate the proportion of severe diarrhoeal cases that were admitted to surveillance hospitals and estimated the population-based incidence of severe diarrhoea due to V. cholerae by combining both hospital surveillance and catchment area survey data. The estimated incidence of severe diarrhoea due to cholera ranged from 0.3 to 4.9/1000 population in the catchment area of surveillance hospitals. In children aged <5 years, incidence ranged from 1.0 to 11.0/1000 children. Diarrhoeal deaths were most common in the Chhatak Hospital's catchment area (18.5/100 000 population). This study provides a credible estimate of the incidence of severe diarrhoea due to cholera in Bangladesh, which can be used to assess the cost-effectiveness of cholera prevention activities.

Hospital-based diarrhoeal disease surveillance has been ongoing in six Bangladeshi hospitals where a systematic proportion of patients admitted with diarrhoea were enrolled and tested for Vibrio cholerae.

We conducted a healthcare utilization survey in the catchment areas of surveillance hospitals to estimate the proportion of severe diarrhoeal cases that were admitted to surveillance hospitals and estimated the population-based incidence of severe diarrhoea due to V. cholerae by combining both hospital surveillance and catchment area survey data. The estimated incidence of severe diarrhoea due to cholera ranged from 0·3 to 4·9/1000 population in the catchment area of surveillance hospitals. In children aged <5 years, incidence ranged from 1·0 to 11·-0/1000 children. Diarrhoeal deaths were most common in the Chhatak Hospital’s catchment area (18·5/100 000 population). This study provides a credible estimate of the incidence of severe diarrhoea due to cholera in Bangladesh, which can be used to assess the cost-effectiveness of cholera prevention activities.

    A novel water quality intervention that consists of point-of-use water disinfection, safe storage and community education was field tested in Bolivia. A total of 127 households in two periurban communities were randomized into intervention and control groups, surveyed and the intervention was distributed. Monthly water quality testing and weekly diarrhoea surveillance were conducted. Over a 5-month period, intervention households had 44% fewer diarrhoea episodes than control households (P = 0.002). Infants < 1 year old (P = 0.05) and children 5-14 years old (P = 0.01) in intervention households had significantly less diarrhoea than control children. Campylobacter was less commonly isolated from intervention than control patients (P = 0.02). Stored water in intervention households was less contaminated with Escherichia coli than stored water in control households (P < 0.0001). Intervention households exhibited less E. coli contamination of stored water and less diarrhoea than control households. This promising new strategy may have broad applicability for waterborne disease prevention. PMID:10098789

    The human gut microbiota play a vital role in health and nutrition but are greatly modified during severe diarrhoea due to purging and pathogenic colonization. To understand the extent of loss during and after diarrhoea, faecal samples collected from children (n=21) suffering from acute diarrhoea and from their healthy siblings (n=9) were analyzed by 16S rRNA gene-targeted universal primer polymerase chain reaction (PCR), followed by temporal temperature gradient gel electrophoresis (TTGE). The gut microbiota decreased significantly as indicated by the number of TTGE bands at day 0 of acute diarrhoea [patients vs healthy siblings: 11±0.9 vs 21.8±1.1 (mean ± standard error), p<0.01]. The number of bands showed a steady increase from day 1 to day 7; however, it remained significantly less than that in healthy siblings (15±0.9, p<0.01). These results suggest that appropriate therapeutic and post-diarrhoeal nutritional intervention might be beneficial for the early microbial restoration and recovery.

  8. Perspectives on child diarrhoea management and health service use among ethnic minority caregivers in Vietnam

    PubMed Central

    2011-01-01

    Background In Vietnam, primary government health services are now accessible for the whole population including ethnic minority groups (EMGs) living in rural and mountainous areas. However, little is known about EMGs' own perspectives on illness treatment and use of health services. This study investigates treatment seeking strategies for child diarrhoea among ethnic minority caregivers in Northern Vietnam in order to suggest improvements to health services for EMGs and other vulnerable groups. Methods The study obtained qualitative data from eight months of field work among four EMGs in lowland and highland villages in the Northern Lao Cai province. Triangulation of methods included in-depth interviews with 43 caregivers of pre-school children (six years and below) who had a case of diarrhoea during the past month, three focus group discussions (FGDs) with men, and two weeks of observations at two Communal Health Stations (CHGs). Data was content-analyzed by ordering data into empirically and theoretically inspired themes and sub-categories assisted by the software NVivo8. Results This study identified several obstacles for EMG caregivers seeking health services, including: gender roles, long travelling distances for highland villagers, concerns about the indirect costs of treatment and a reluctance to use government health facilities due to feelings of being treated disrespectfully by health staff. However, ethnic minority caregivers all recognized the danger signs of child diarrhoea and actively sought simultaneous treatment in different health care systems and home-based care. Treatments were selected by matching the perceived cause and severity of the disease with the 'compatibility' of different treatments to the child. Conclusions In order to improve EMGs' use of government health services it is necessary to improve the communication skills of health staff and to acknowledge both EMGs' explanatory disease models and the significant socio-economic constraints

    Childhood poverty is associated with harsh parenting with a risk of transmission to the next generation. This prospective study examined the relations between childhood poverty and non-parent adults’ neural responses to infant cry sounds. While no main effects of poverty were revealed in contrasts of infant cry vs. acoustically matched white noise, a gender by childhood poverty interaction emerged. In females, childhood poverty was associated with increased neural activations in the posterior insula, striatum, calcarine sulcus, hippocampus and fusiform gyrus, while, in males, childhood poverty was associated with reduced levels of neural responses to infant cry in the same regions. Irrespective of gender, neural activation in these regions was associated with higher levels of annoyance with the cry sound and reduced desire to approach the crying infant. The findings suggest gender differences in neural and emotional responses to infant cry sounds among young adults growing up in poverty. PMID:25981334

Passed faecal specimens from 400 patients (250 with and 150 without diarrhoea) up to 60 months of age attending from 2004 to 2007 at two public hospitals were investigated. Conventional microbiology methods and PCR were employed. Escherichia coli was isolated from 390 children, 240 of them with diarrhoea. A total of 117 AEEC strains were cultivated from specimens from 63 children, 37 with and 26 without diarrhoea. No association between AEEC and diarrhoea was observed. Atypical enteropathogenic E. coli (a-EPEC) (79.4%) was more commonly found than typical EPEC (t-EPEC). Association between EPEC and EPEC subtypes and diarrhoea was not detected. Mixed infection by t-EPEC and a-EPEC and infection by Shiga toxin-producing E. coli (STEC) were rare. Enteropathogenic E. coli was more common in males and in children aged less than 12 months. Correlation between serotyping and PCR results was 0.19. High resistance rates of AEEC to ampicillin, cephalotin, and trimethoprim-sulfamethoxazole were found. In conclusion, EPEC is very common in children with diarrhoea and controls in the population we studied, with a-EPEC predominating. This diarrhoeagenic E. coli (DEC) pathotype is more common in infant males and is resistant to drugs frequently used in clinical practice.

    Diarrhoea is a common disease which causes pain and may be deadly, especially in developing countries. In Bangladesh, diarrhoeal diseases affect thousands of people every year, and children are especially vulnerable. Bacterial toxins or viral infections are the most common cause of the disease. The diarrhoea outbreaks are often associated with flood affected areas with contaminated drinking water and an increased risk of spreading the water-borne disease. Not surprisingly, plants found in the near surroundings have been taken into use by the local community as medicine to treat diarrhoeal symptoms. These plants are cheaper and more easily available than conventional medicine. Our question is: What is the level of documentation supporting the use of these plants against diarrhoea and is their consumption safe? Do any of these plants have potential for further exploration? In this review, we have choosen seven plant species that are used in the treatment of diarrhoea; Diospyros peregrina, Heritiera littoralis, Ixora coccinea, Pongamia pinnata, Rhizophora mucronata, Xylocarpus granatum, and Xylocarpus moluccensis. Appearance and geographical distribution, traditional uses, chemical composition, and biological studies related to antidiarrhoeal activity will be presented. This review reveals that there is limited scientific evidence supporting the traditional use of these plants. Most promising are the barks from D. peregrina, X. granatum and X. moluccensis which contain tannins and have shown promising results in antidiarrhoeal mice models. The leaves of P. pinnata also show potential. We suggest these plants should be exploited further as possible traditional herbal remedies against diarrhoea including studies on efficacy, optimal dosage and safety. PMID:23698166

    This study was conducted to evaluate the efficacy and safety of Saccharomyces boulardii strain Unique 28 in patients suffering from acute diarrhoea. A total of 25 patients (average age 30.72±4.38 years) with symptoms of acute diarrhoea (≥3 loose motion in last 24 hours for <7 days) were included upon informed consent and ethical committee approval. All subjects were assigned to consume S. boulardii strain Unique 28 (5×109 cfu/capsule) twice a day for a duration of 10 days. Primary outcome measures such as duration of diarrhoea, frequency of defaecation, abdominal pain and consistency of stool were analysed on day 1, 3, 6 and 10 of the study. Secondary outcome measures were evaluated by assessment of incidence and type of adverse events (blood pressure and pulse rate), physical examination and clinical laboratory tests (complete blood count, glutamic-pyruvic transaminase, serum creatinine, stool examination and microscopy and these tests were performed on day 1 and 10 of the study. The results of the present study indicate that the mean duration of diarrhoea decreased from 34.20±4.25 to 9.40±3.00 (P<0.0001) min per day, frequency of defaecation decreased from 7.04±0.84 to 1.76±0.52 (P<0.0001) times a day, abdominal pain decreased from 3.28±1.06 (severe) to 0.72±0.50 (absent) (P<0.0001) and consistency of stool improved from 3.80±0.50 (watery) to 1.32±0.47 (soft) (P<0.0001). In addition, no significant changes in safety parameters were observed during treatment. Therefore, the present study concludes that S. boulardii strain Unique-28 might be useful in alleviating the symptoms of diarrhoea without any adverse effects.

    This study aimed to examine the aetiology of acute diarrhoea and the relapse rate in 100 client-owned dogs presented to a first-opinion clinic. History, physical examination, faecal testing and owner questionnaire data were collected at initial presentation (T0) and at either the time of relapse or at a recheck performed within 3 months. All dogs received treatment according to their clinical signs. Of 96 dogs that completed the study, 37 (38.5%) relapsed during the study period, 21 (21.9%) relapsed within 3 months, and 16 others (16.6%) at 3 months to 1 year after initial examination. Dogs that had undergone a change in housing location within 1 month prior to presentation and dogs <1 year old were significantly more likely to have positive parasitological analyses (P=0.02 and P=0.001, respectively). Pica was a risk factor for relapse (P=0.0002).

    Gastrointestinal helminthiasis in developing countries contributes to malnutrition and anemia. Diagnosis and treatment of helminthiasis, especially with low worm load is an unmet public health need in such settings. The infection may sometimes become manifest when a second pathology leads to purgation of the gastrointestinal tract. Two cases of helminthiasis are presented in which the infections only became amenable to diagnosis due to acute diarrhoea caused by giardiasis and lactulose administration. In the first case, acute giardiasis revealed Ascaris lumbricoides infestation, and in the second case primary helminthiasis (strongyloidiasis) was revealed by lactulose, and also led to Vibrio cholera bacteremia. These cases highlight the need to diagnose helminth infestations especially with low worm burdens by means of public health surveillance programmes.

    All 250 children presenting with diarrhoea at 2 teaching hospitals in Mosul, Iraq over a 9-month period were studied for the presence of Yersinia spp. in stools by cold-enrichment culture at 4 degrees C for 21 days. Pathogenicity of the isolated Yersinia was determined. Antibodies to Y. enterocolitica were raised for rapid Yersinia detection in the stool. Yersinia spp. were isolated from the stools of only 4 patients; 3 isolates were identified as Y. enterocolitica and 1 was Y. pseudotuberculosis. The blood culture was also positive for Y. enterocolitica in 1 case. The antibiogram test for the isolated Yersinia was determined. Cross-reaction between Y. pseudotuberculosis and Salmonella typhi or S. paratyphi B, and between Y. enterocolitica and Brucella was detected serologically.

    At present, national-level policies concerning the eradication and control of bovine viral diarrhoea (BVD) differ widely across Europe. Some Scandinavian countries have enacted strong regulatory frameworks to eradicate the disease, whereas other countries have few formal policies. To examine these differences, the attitudes of stakeholders and policy makers in 17 European countries were investigated. A web-based questionnaire was sent to policy makers, government and private sector veterinarians, and representatives of farmers' organisations. In total, 131 individuals responded to the questionnaire and their responses were analysed by applying a method used in sociolinguistics: frame analysis. The results showed that the different attitudes of countries that applied compulsory or voluntary frameworks were associated with different views about the attribution or blame for BVD and the roles ascribed to farmers and other stakeholders in its eradication and control.

    Although some studies suggested specific foods/beverages as risk factors for travellers' diarrhoea (TD), details of transmission remain unclear. We assessed the influence of travel style (luxury/middle-class versus backpacking) on TD risk. TD attack rates were compared in a prospective study among travellers to India at the University of Zurich's Travel Clinic. Information on consumption of foods/beverages was collected. Seventy-one luxury/middle-class travellers and 21 backpackers completed the study; overall 37% suffered from TD (62% backpackers, 30% luxury/middle-class travellers, OR 4.43, p 0.022). Travel style rather than the consumption of specific foods/beverages appears to be a risk factor for TD development.

    To explore the association between rotavirus (RV) infection and histo-blood group antigens (HBGAs), a cross-sectional study was conducted in children hospitalized with diarrhoea in China from November 2014 to February 2015. In total, 424 sets of stool, saliva and buccal cell samples were collected. For the 125 RV-negative samples, 92% (104/125) were secretors/partial secretors, 8% (10/125) were non-secretors. Among the 299 RV-positive samples, 277 were P[8] and 22 were P[4]. All P[4] and P[8] positive individuals were secretors/partial secretors except for one P[8] (0.3%, 1/299), which was a non-secretor. These findings indicate that P[8] and P[4] RVs preferably infect secretors/partial secretors (p <0.001).

    The antibacterial effect of local honey on local isolates of bacterial agents of diarrhoea was determined by an in vitro method involving the impregnation of filter paper discs in undiluted honey and different honey concentrations ranging from 10%-50%. The discs were later placed on plates that have been seeded with the different bacteria and zones of inhibition of growth were measured after a 48 hr. period of incubation. Results presented show that undiluted honey and honey at concentrations of 40% and above were inhibitory to all enteropathogens tested. Zones of inhibition of growth around the disc margin of the various enteropathogens tested ranged from 16-18mm in diameter for the local undiluted honey and 7-12mm in diameter for concentrations of honey at 40% and 50%. The possible mechanisms of this inhibitory effect of local honey are discussed.

    Escherichia coli was isolated in 382 (94 per cent) of 406 children from 0 to 3 years of age who had been hospitalized for diarrhoea at the Hospital Municipal Salles Neto, Rio de Janeiro. Enteropathogenic Escherichia coli strains were isolated in 67 samples (18 per cent), distributed among the serogroups that were tested as follows: 0111 (33 per cent); 0125 (19 per cent); 0126, 0127, and 0142 (9 per cent); 0128 and 0119 (8 per cent); 055 (5 per cent); 0114 (2 per cent). No strains of EPEC belonging to serogroups 086, 0126, and 0158 were found. Among the samples in which EPEC strains were isolated, 15.0 per cent were children living in dwellings which had piped systems of water supply and drain, whereas with regard to those living in houses without such facilities, this percentage raised to 24 per cent. Similar results were found when the availability of water supply of drainage were taken separately.

    Microscopic colitis is a generic term that includes 2 main forms, collagenous colitis and lymphocytic colitis, and describes a form of inflammatory bowel disease with a chronic and relapsing course. The incidence of microscopic colitis is between 2 and 8 times higher in women than in men, although age, more than sex, increases the risk of collagenous colitis (odds ratio [OR] 8.3 for age ≥65 vs. <65 and OR 2.8 for women). The main symptom is chronic non-bloody watery diarrhoea. Other common symptoms include abdominal pain (50%-70%), with the result that many patients with microscopic colitis meet criteria for irritable bowel syndrome. Colonoscopy with multiple colonic biopsies is currently recommended, as histological changes are the main characteristic feature. The colonic mucosa is macroscopically normal, although certain minimal endoscopic abnormalities have been described.

    Four, 1-to 4-week-old ferret kits were submitted to the Diagnostic Center for Population and Animal Health at Michigan State University for post-mortem examination. Grossly, multiple bowel loops in all ferret kits were distended by mucoid faecal material. Microscopically, there was no evidence of inflammation or notable alteration to the normal mucosal morphology. Gram-positive coccoid bacteria colonized variable segments of the small intestine. These bacteria were identified as Staphylococcus delphini by phenotypic and molecular analyses. Enzyme-linked immunosorbent assay for detection of Staphylococcus enterotoxins was positive and polymerase chain reaction detected the gene for Staphylococcus enterotoxin E in the isolates. The hypersecretory diarrhoea in these ferret kits may have been associated with colonization of the small intestine by S. delphini, cultures of which were shown in vitro to be potentially capable of producing enterotoxin E. The condition described in these ferrets is similar to 'sticky' kit syndrome in mink.

    A study was performed to survey the virological prevalence of bovine viral diarrhoea (BVD) virus (BVDV) in cattle herds in Hungary between 2008 and 2012. A total of 40,413 samples for BVDV detection and 24,547 samples for antibody testing were collected from 3,247 herds (570,524 animals), thus representing approximately 75% of the cattle population in Hungary. Retrospective Bayesian analysis demonstrated that (1) the herd-level true virus prevalence was 12.4%, (2) the mean individual (within-herd) true virus prevalence was 7.2% in the herds having at least one virus-positive animal and 0.89% for all investigated herds with a mean apparent prevalence of 1.15% for the same population. This is the first study about BVDV prevalence in Hungary.

    Thirty one out of 153 strains of Shigella sonnei isolated from Thai patients with diarrhoea showed antibacterial activity against S. sonnei by agar well diffusion method. All of them harbor plasmids with the genetic determination of colicin type 7 (Js) gene but without colicin E and colicin U gene. The PCR product obtained from strain 35/44 was shown to be the gene for colicin type 7 lytic protein (cja). The partially purified bacteriocin (PPB) containing colicin type 7 of strain 35/44 was prepared and used for characterization. The antibacterial activity of PPB against a total of 17 selected Gram-positive and Gram-negative bacteria was tested. It was found that PPB of strain 35/44 was active against E. coli O157, S. sonnei and S. boydii. The sensitivity of PPB from this strain to proteinase K, trypsin and α-chymotrypsin suggests the proteinaceous nature of these antimicrobial substances. Therefore, this isolated bacterium can be regarded as bacteriocin producing bacteria. The bacteriocin produced by this isolated S. sonnei was heat stable as evidenced by its ability to maintain the activity at 80 °C for 60 min. In addition, it was stable within a wide range of pH (3-9). The molecular weight of colicin type 7 from isolated S. sonnei strain 35/44 analyzed by SDS-PAGE was 54.4 kDa composing of at least five subunits. It is to our knowledge; the first report of Thai patients with diarrhoea that S. sonnei isolated from them contained colicin type 7.

    This study involved 13 calves, one to 50 days of age, born to first calf heifers that had been pastured on one of seven alpine communal pastures in the canton of St. Gallen during the summer of 1995. Of a total of 993 cattle pastured, 61 were pregnant heifers that were negative for bovine virus diarrhoea (BVD) antigen and for BVD antibodies at the start of pasturing. Seroconversion occurred in 26 of these pregnant heifers during the pasture period. Blood samples and skin biopsy specimens of calves born to 13 of these were examined for BVD antigen by antigen-ELISA and by an immunohistochemical technique, respectively. Blood samples were positive for BVD antigen in four calves, questionable in one calf, negative in seven and missing in one prematurely born calf. The four calves that were positive for BVD antigen in the blood were also positive in skin biopsies. Of the seven calves with a negative or missing blood test, six had positive and two had negative skin samples. Based on the combined results of blood and skin testing, 11 of 13 calves were positive for BVD antigen. Of the 11 infected calves, six were normal at birth, four were smaller than normal and one was premature and weak and was euthanized on humane grounds. Of the four small calves, two developed diarrhoea and died within the first month of life. The two calves that were negative for BVD antigen were clinically normal. The results of this study not only demonstrate the occurrence of in-utero infection with BVD virus, but also stress the importance of alpine communal pasturing in the spread of BVD virus. Because the prevention of infection with BVD virus on communal pastures does not seem feasible, it is recommended that all calves born to cows from such pastures be tested for BVD antigen.

    Dysentery is endemic in Zimbabwe. More than 260,000 cases and a case fatality of four per thousand were reported in 1993. In late July 1994, the Health Services Department in Bulawayo was informed of two cases of Shigella dysenteriae type I at a textile factory that employs 138 workers. Workers were interviewed at the factory regarding the date of the onset of illness, symptoms, food consumed, and treatment received. Factory water supply, cooking, and sanitary facilities were inspected. Stool and water samples were obtained for analysis. A case was defined as an employee presenting with diarrhoea with onset from July 24 to August 25, 1994. Of the 99 workers on day and evening shifts, 75 (75%) were interviewed. Thirty eight workers met the case definition (Attack Rate 51%). Common symptoms were abdominal cramps (71%), and blood in stools (37%); median duration of diarrhoea was 11 days (range 5 to 32 days). Thirty seven (64%) of 58 workers who drank borehole water were ill compared to one (6%) of the 17 who did not (RR = 10.8, 95% CI = 1.6-73). No food items consumed were significantly associated with the illness. Two different shigella species (2 sonnei and 2 boydii) were isolated from five (13%) of 38 stool specimens. Water samples from the two boreholes yielded numerous faecal coliforms. Neither borehole was registered as required by the municipal bylaws, which also forbid use of borehole water for drinking. The epidemiologic and laboratory evidence implicate contaminated borehole water as the most likely cause of this outbreak. Enforcement of municipal bylaws on drilling, registration and use of boreholes is essential to avoid further outbreaks of waterborne diseases.

    This field study explored the cytokine expression in intestinal tissue and serum from 19 diarrhoeic and 9 healthy pigs in herds with a long-time history of Lawsonia intracellularis-infection. The disease, proliferative enteropathy (PE), is associated with diarrhoea and poor performance in growers and haemorrhagic diarrhoea and sudden death in finisher pigs, but the immunopathology is poorly understood. Histopathology, demonstration of L. intracellularis and porcine circovirus type 2 (PCV2) in intestinal tissue by PCR, and detection of serum antibodies to L. intracellularis, were performed. The presence of IL-1β, IL-6, IL-10, IFN-α, IFN-γ, TNF-α and TGF-β in sera was determined by immunoassays, and intestinal mRNA expression of these cytokines plus IL-12p40 was determined by qPCR. Intestinal specimens from pigs with intestinal adenomatosis (n=2), proliferative haemorrhagic enteropathy or swine dysentery (n=2), and controls (n=2) were analysed by a genome wide porcine microarray. The clinical signs of PE were not always supported by the subsequent analyses, and the presence of PCV2 may have contributed to an increased mRNA expression for IFN-γ in intestinal specimens from some pigs. The limited gene expression in the microarray analyses and the limited expression of cytokines in both sera and intestines, indicate that the immune response is poorly activated in the initial course of an infection with L. intracellularis. However, the gene encoding for insulin-like growth factor binding protein 3 (IGFBP-3) was up-regulated in two pigs with prominent mucosal proliferation.

    Eimeria and Cryptosporidium are among the most common bovine parasites in the world, but little is known about them in Estonia. Basic field research is needed to gain insight into pathogen dynamics, providing knowledge for veterinarians and research. A survey of 45 Estonian dairy farms in 15 counties was carried out between 2006 and 2007. Three age groups: <3, 3-12, and >12 months old animals were sampled. Collected faeces were examined by quantitative flotation and Ziehl-Neelsen contrast staining, and species examined morphologically. Selected samples containing Cryptosporidium were additionally examined by polymerase-chain-reaction (PCR) and sequencing to determine genotypes. Twelve species of Eimeria were identified, seven previously unknown in Estonia. Main species in samples were E. bovis (30%), E. zuernii (23%), and E. ellipsoidalis (14%). All herds were infected and animals aged 3-12 months were more commonly infected with Eimeria oocysts (63%) than any other group. Calves <3 months shed most oocyst, but high counts were rare. A negative association (slope=-0.16, p<0.001) was found between the number of animals infected with Eimeria and the age category. Cryptosporidium were detected in 84% of the farms, and C. andersoni and C. parvum were successfully identified. Though prevalences of Cryptosporidium in the age groups were similar to the sample prevalence (30%) an increase in the infections was found with increasing age (p<0.001). Higher diarrhoea scores were negatively associated with Eimeria spp. infection (slope=-0.08, p<0.05), whereas Cryptosporidium could not be associated with the presence of diarrhoea. Frequent low intensity infections of animals in all age groups with both parasites apply a constant stress on the animals with impact on health and production. The Estonian results are different compared to available studies in regard of: older animals commonly being infected, finding of modest oocyst counts, and distribution of Eimeria species.

    Bovine viral diarrhoea virus is a pathogen of bovids associated with reproduction system, causing in infected animals a range of ailments, from abortion to congenital defects. In this article, the nucleotide structure of the 5'-untranslated region (5-UTR) from 7 Iranian bovine diarrhoea virus (BVDV) isolates was characterized and subjected to comparative analysis against a panel of BVDV isolates from different sources. To this end, a 288 bp-long stretch of the internal ribosome entry site was amplified by RT-PCR. The PCR products subsequently cloned into PTZ57T vector and sequenced using T7 promoter primers. This resulted in detection of 3 new point mutations G → A and G → T in 2 isolates. When these findings were phylogenetically assessed, all the examined Iranian isolates were deemed to belong to the type1 of BVDV. Besides, 2 subtypes were identified among these isolates. In group A, a high level of similarity (99.2%) between Iranian isolates with a cytopathic Australian strain of BVDV-1c was detected; while in group B, the 4 Iranian isolates proved to be very similar to NADL-like BVDV-1a strains. We believe that the surprisingly high level of similarity between group A Iranian isolates and their corresponding Australian strain is likely to be an indication of a shared common ancestor. If correct, the most likely explanation of this observation is the introduction of such strains from Australia to Iran, possibly through exportation of infected live animals or animal productions (e.g. semen and meat) at some points in the past. Nevertheless, this hypothesis remains to be proved as further epidemiological work at genomic level is required to understand population of BVDV in Iran.

    Cilansetron is a novel serotonin type-3 (5-hydroxytryptamine; 5-HT) receptor subtype 3 (5-HT(3)) receptor antagonist currently being evaluated for the treatment of female and male patients with irritable bowel syndrome with diarrhoea predominance (IBS-D). 5-HT(3) receptor antagonists such as cilansetron have been shown to affect gastrointestinal motility. Whether cilansetron affects visceral sensation independent of effects on visceral compliance remains controversial. Results from two large, randomised, double-blind, placebo-controlled, parallel-group Phase III clinical trials of cilansetron in patients with IBS-D have recently been presented in abstract form. These studies found that cilansetron was more effective than placebo at improving overall, as well as individual symptoms, including abdominal pain and diarrhoea in female and male IBS-D patients. The most commonly reported side effect with cilansetron has been constipation and, in general, the drug has been well tolerated in clinical trials. Although rare, the most concerning side effect observed with cilansetron has been suspected ischaemic colitis. The event rate for suspected ischaemic colitis associated with cilansetron from clinical trials is 3.77 per 1000 person years of exposure. This rate appears to be greater than that expected in the IBS population and similar to that observed with alosetron, another 5--HT(3) receptor antagonist. All of the cases of suspected ischaemic colitis reported with cilansetron have resolved without serious sequelae. How issues surrounding the safety of cilansetron will affect the approval process in various countries remains to be determined. However, the risk-benefit of cilansetron is likely to be most favourable in patients with IBS-D who have failed to respond to conventional medical therapies. A detailed risk management plan and post-marketing surveillance programme will be required should this drug become available for the treatment of patients with IBS-D.

    OBJECTIVE To identify the common serotypes and antimicrobial resistance patterns of Salmonella spp. associated with diarrhoea in Australian dairy calves under the age of 6 weeks. DESIGN Cross-sectional study. METHODS Faecal samples were collected from outbreaks of diarrhoea in dairy and dairy beef calves less than 6 weeks old. Samples were screened for Salmonella using standard enrichment culture techniques. The antimicrobial susceptibility to 12 commonly used veterinary and human antimicrobials was assessed using the Kirby-Bauer disk diffusion method and the susceptibility profiles of dairy and dairy beef properties were compared using Fisher's exact test. RESULTS Salmonella ser. Dublin, S. ser. Typhimurium and S. ser. Bovismorbificans were the three most common salmonella serotypes isolated. The majority of properties had one serotype. Most of the Salmonella isolates were not resistant to any of the antimicrobials tested. No resistance was seen to amikacin and nalidixic acid, and only one isolate was resistant to ceftiofur or amoxicillin-clavulanic acid. The most common antimicrobial resistance was to streptomycin, ampicillin or combination sulfonamides. Multi-drug resistance was detected in S. ser. Anatum, S. ser. Bovismorbificans, S. ser. Muenster, S. ser. Newport and S. ser. Typhimurium. Isolates from dairy beef properties were more likely to be resistant to ampicillin, kanamycin, neomycin, sulfamethoxazole/trimethoprim and tetracycline (P < 0.05) and were more likely to exhibit multi-drug resistance. CONCLUSION The prevalence of antimicrobial resistance in Salmonella isolates from dairy calves in Australia is low compared with that reported overseas. From a human health perspective, resistance to antimicrobials used in the treatment of human salmonellosis was infrequent.

    Background The adverse impact of Plasmodium vivax on child health beyond acute febrile illness is poorly studied. The effect of vivax malaria on child growth was evaluated and compared with diarrhoeal disease and non-specific fever. Methods Using data from a 43-month longitudinal cohort of children 0–72 months of age (n = 442) in the Peruvian Amazon, ponderal and linear growth velocities over 2-, 4- and 6-month periods were examined using longitudinal models and related to the incidence of disease during the same period. Results An episode of vivax malaria led to 138.6 g (95% confidence interval (CI) 81.9–195.4), 108.6 g (62.8–153.2) and 61 g (20.9–101.1) less weight gain over 2-, 4- and 6-month intervals, respectively. These deficits were larger than both diarrhoea (21.9, 17.2 and 13.8 g less weight gain, respectively) and fever (39.0, 30.3 and 25.6 g less weight gain, respectively). An incident episode of vivax also led to 0.070 cm (0.004–0.137) and 0.083 cm (0.015–0.151) less linear growth over 4 and 6 months, respectively, which were also larger than deficits from diarrhoea (0.029 and 0.028 cm, respectively) and fever (not associated with linear growth deficits). Despite the larger effect of P. vivax incident episodes on growth of a particular child, diarrhoeal disease had a larger cumulative impact on growth deficits as diarrhoeal incidence rates in this community are >10-fold higher than vivax malaria. Conclusions Disease control measures for vivax malaria and diarrhoeal disease have the potential to improve the growth of children in endemic areas. PMID:22258823

    Neonatal calf diarrhoea remains the most common cause of morbidity and mortality in preweaned dairy calves worldwide. This complex disease can be triggered by both infectious and non-infectious causes. The four most important enteropathogens leading to neonatal dairy calf diarrhoea are Escherichia coli, rota- and coronavirus, and Cryptosporidium parvum. Besides treating diarrhoeic neonatal dairy calves, the veterinarian is the most obvious person to advise the dairy farmer on prevention and treatment of this disease. This review deals with prevention and treatment of neonatal dairy calf diarrhoea focusing on the importance of a good colostrum management and a correct fluid therapy.

    Childhood experience with a language seems to help adult learners speak it with a more native-like accent. Can analogous benefits be found beyond phonology? This study focused on adult learners of Spanish who had spoken Spanish as their native language before age 7 and only minimally, if at all, thereafter until they began to re-learn Spanish around age 14 years. They were compared with native speakers, childhood overhearers, and typical late-second-language (L2)-learners of Spanish. Both childhood speakers and overhearers spoke Spanish with a more native-like accent than typical late-L2-learners. On grammar measures, childhood speakers—although far from native-like—reliably outperformed childhood overhearers as well as typical late-L2-learners. These results suggest that while simply overhearing a language during childhood could help adult learners speak it with a more native-like phonology, speaking a language regularly during childhood could help re-learners use it with more native-like grammar as well as phonology.

    This article assesses the role played by media in contributing to the current epidemic of childhood obesity. Electronic media use, often referred to as screen time, is significantly correlated with child adiposity. Although the causal mechanism that accounts for this relationship is unclear, it is well established that reducing screen time improves weight status. Media advertising for unhealthy foods contributes to obesity by influencing children's food preferences, requests, and diet. Industry efforts have failed to improve the nutritional quality of foods marketed on television to children, leading public health advocates to recommend government restrictions on child-targeted advertisements for unhealthy foods.

    Craniopharyngioma is a rare, benign central nervous system tumor, which may be a source of multiple complications, from endocrinology to vision, neurology and neurocognitive functions. This morbidity can lead to reduced participation in life activities, as described in the International Classification of Functioning, Disability, and Health. The primary objective of this study was to measure participation in life activities in a population of children and young adults affected by childhood craniopharyngioma, using the LIFE-H questionnaire (Assessment of Life Habits), validated as a social participation measurement tool in various pediatric disabilities. We also describe complications in our population and examined the potential links between tumor characteristics, complications, and participation in life activities.

  18. Pesticides and childhood cancer.

    PubMed Central

    Zahm, S H; Ward, M H

    1998-01-01

    Children are exposed to potentially carcinogenic pesticides from use in homes, schools, other buildings, lawns and gardens, through food and contaminated drinking water, from agricultural application drift, overspray, or off-gassing, and from carry-home exposure of parents occupationally exposed to pesticides. Parental exposure during the child's gestation or even preconception may also be important. Malignancies linked to pesticides in case reports or case-control studies include leukemia, neuroblastoma, Wilms' tumor, soft-tissue sarcoma, Ewing's sarcoma, non-Hodgkin's lymphoma, and cancers of the brain, colorectum, and testes. Although these studies have been limited by nonspecific pesticide exposure information, small numbers of exposed subjects, and the potential for case-response bias, it is noteworthy that many of the reported increased risks are of greater magnitude than those observed in studies of pesticide-exposed adults, suggesting that children may be particularly sensitive to the carcinogenic effects of pesticides. Future research should include improved exposure assessment, evaluation of risk by age at exposure, and investigation of possible genetic-environment interactions. There is potential to prevent at least some childhood cancer by reducing or eliminating pesticide exposure. PMID:9646054

    1997-01-01

    To evaluate the possible association between pesticides and the risk of childhood cancers, epidemiologic studies published between 1970 and 1996 were critically reviewed. Thirty-one studies investigated whether occupational or residential exposure to pesticides by either parents or children was related to increased risk of childhood cancer. In general, the reported relative risk estimates were modest. Risk estimates appeared to be stronger when pesticide exposure was measured in more detail. Frequent occupational exposure to pesticides or home pesticide use was more strongly associated with both childhood leukemia and brain cancer than either professional exterminations or the use of garden pesticides. Occupational pesticide exposure was also associated with increased risk of Wilms' tumor, Ewing's sarcoma, and germ cell tumors. Residence on a farm, a proxy for pesticide exposure, was associated with increased risk of a number of childhood cancers. Although increased risk of some childhood cancers in association with pesticide exposure is suggested by multiple studies, methodological limitations common to many studies restrict conclusions; these include indirect exposure classification, small sample size, and potential biases in control selection. Opportunities for methodologic improvement in future studies of pesticides and childhood cancers are described. PMID:9349828

  5. Neurofunctional Abnormalities during Sustained Attention in Severe Childhood Abuse

    2016-01-01

    Childhood maltreatment is associated with adverse affective and cognitive consequences including impaired emotion processing, inhibition and attention. However, the majority of functional magnetic resonance imaging (fMRI) studies in childhood maltreatment have examined emotion processing, while very few studies have tested the neurofunctional substrates of cognitive functions and none of attention. This study investigated the association between severe childhood abuse and fMRI brain activation during a parametric sustained attention task with a progressively increasing load of sustained attention in 21 medication-naïve, drug-free young people with a history of childhood abuse controlling for psychiatric comorbidities by including 19 psychiatric controls matched for psychiatric diagnoses, and 27 healthy controls. Behaviorally, the participants exposed to childhood abuse showed increased omission errors in the task which correlated positively trend-wise with the duration of their abuse. Neurofunctionally, the participants with a history of childhood abuse, but not the psychiatric controls, displayed significantly reduced activation relative to the healthy controls during the most challenging attention condition only in typical attention regions including left inferior and dorsolateral prefrontal cortex, insula and temporal areas. We therefore show for the first time that severe childhood abuse is associated with neurofunctional abnormalities in key ventral frontal-temporal sustained attention regions. The findings represent a first step towards the delineation of abuse-related neurofunctional abnormalities in sustained attention, which may help in the development of effective treatments for victims of childhood abuse.

    In Tlaxcala State, Mexico, we determined that 80% of children who died from diarrhoea or acute respiratory infections (ARI) received medical care before death; in more than 70% of the cases this care was provided by a private physician. Several strategies have been developed to improve physicians' primary health care practices but private practitioners have only rarely been included. The objective of the present study was to evaluate the impact of in-service training on the case management of diarrhoea and ARI among under-5-year-olds provided by private and public primary physicians. The training consisted of a five-day course of in-service practice during which physicians diagnosed and treated sick children attending a centre and conducted clinical discussions of cases under guidance. Each training course was limited to six physicians. Clinical performance was evaluated by observation before and after the courses. The evaluation of diarrhoea case management covered assessment of dehydration, hydration therapy, prescription of antimicrobial and other drugs, advice on diet, and counselling for mothers; that of ARI case management covered diagnosis, decisions on antimicrobial therapy, use of symptomatic drugs, and counselling for mothers. In general the performance of public physicians both before and after the intervention was better than that of private doctors. Most aspects of the case management of children with diarrhoea improved among both groups of physicians after the course; the proportion of private physicians who had five or six correct elements out of six increased from 14% to 37%: for public physicians the corresponding increase was from 53% to 73%. In ARI case management, decisions taken on antimicrobial therapy and symptomatic drug use improved in both groups; the proportion of private physicians with at least three correct elements out of four increased from 13% to 42%, while among public doctors the corresponding increase was from 43% to 78%.

    Berberine, a compound isolated from Chinese Goldthread Rhizome, has been widely used as a non-prescription drug to treat diarrhoea in China. Previous studies have demonstrated multiple pharmacological activities for berberine, including its significant role in antimicrobial activity. However, its effect on ion exchange and water transfer remains unclear. The present study aims to explore the effect of berberine on the expression of Na(+)/H(+) exchanger3 (NHE3) and aquaporin4 (AQP4) in both diarrhoea mouse model induced by sennosideA and human intestinal epithelium cell line (HIEC). Semi-quantitative RT-PCR, immunohistochemistry and western blotting were adopted to detect the mRNA and protein expression levels of NHE3 and AQP4. Furthermore, the absorption of berberine and the PKC activity were detected by HPLC and PepTag® Assay to elucidate the underlying mechanisms. It was shown that the expression levels of NHE3 and AQP4 were significantly increased in the diarrhoea mice treated with berberine compared with the untreated diarrhoea mice. Similarly, the expression levels of NHE3 and AQP4 were strikingly enhanced in HIEC co-treated with sennosideA and berberine compared with samples treated with sennosideA only. We also found the maximal absorption of berberine to be approximately 0.01%. In addition, no significant change of PKC activity was observed in the different HIEC treated groups. These results showed that berberine was able to increase the expression of NHE3 and AQP4, suggesting that berberine might exhibit its anti-diarrhoeal effect partially by enhancing the absorption of Na(+) and water.

    The yak (Bos grunniens) is an iconic symbol in the high-altitude region of the Qinghai–Tibetan Plateau. Diarrhoea is a common disease in yaks, resulting in major economic losses. To investigate the diversity of viral species, we reported the metagenomics-derived virome in a pooled faecal sample of 20 diarrhoeic yaks. The nine viruses found in the pooled diarrhoeic samples, in order of abundance of nucleic acid sequence, were influenza A virus, bovine viral diarrhoea virus (BVDV), rotavirus, ungulate tetraparvovirus 1 (bovine hokovirus), astrovirus (AstV), bovine enterovirus, hepatitis E virus, kobuvirus and woodchuck hepatitis virus. Compared with healthy yaks, only AstV had a significantly higher prevalence rate in diarrhoeal samples, indicating a correlation with the clinical symptoms of diarrhoea in yaks. To further investigate the molecular characterization of yak AstV, a near-full genome was obtained from a diarrhoeic sample. It was 6243 bp in length and shared 46.4–66.2 % similarity with other related bovine AstVs from faeces. Phylogenetic analysis of the genome demonstrated that the yak AstV fell within the bovine AstVs cluster, but was located in a unique lineage, suggesting a novel AstV species was identified in yaks. Interestingly, the ORF2 region of yak AstV had closer similarity and genetically relationship with deer AstV strain CcAstV-2 than that of the bovine AstVs. Further analysis showed that one possible interspecies recombination event occurred in ORF2. In summary, this study expanded our understanding of the viral communities of diarrhoeal yaks and identified a novel AstV that was associated with diarrhoea in yaks.

    Data on the number of admissions for diarrhoea each week to the West Kalimantan Provincial Hospital, Pontianak, Indonesia over a 5 year period, 1992-1996, were collected. After cleaning and exclusion of extreme values, transformation was then performed to ensure that the data were free of special cause variation and normally distributed. A control chart was then constructed to provide an 'early warning' system for hospital authorities in order to facilitate the management of the epidemic and to improve patient care.

    Background The recent series of reviews conducted within the Global Action Plan for Pneumonia and Diarrhoea (GAPPD) addressed epidemiology of the two deadly diseases at the global and regional level; it also estimated the effectiveness of interventions, barriers to achieving high coverage and the main implications for health policy. The aim of this paper is to provide the estimates of childhood pneumonia at the country level. This should allow national policy–makers and stakeholders to implement proposed policies in the World Health Organization (WHO) and UNICEF member countries. Methods We conducted a series of systematic reviews to update previous estimates of the global, regional and national burden of childhood pneumonia incidence, severe morbidity, mortality, risk factors and specific contributions of the most common pathogens: Streptococcus pneumoniae (SP), Haemophilus influenzae type B (Hib), respiratory syncytial virus (RSV) and influenza virus (flu). We distributed the global and regional–level estimates of the number of cases, severe cases and deaths from childhood pneumonia in 2010–2011 by specific countries using an epidemiological model. The model was based on the prevalence of the five main risk factors for childhood pneumonia within countries (malnutrition, low birth weight, non–exclusive breastfeeding in the first four months, solid fuel use and crowding) and risk effect sizes estimated using meta–analysis. Findings The incidence of community–acquired childhood pneumonia in low– and middle–income countries (LMIC) in the year 2010, using World Health Organization's definition, was about 0.22 (interquartile range (IQR) 0.11–0.51) episodes per child–year (e/cy), with 11.5% (IQR 8.0–33.0%) of cases progressing to severe episodes. This is a reduction of nearly 25% over the past decade, which is consistent with observed reductions in the prevalence of risk factors for pneumonia throughout LMIC. At the level of pneumonia incidence

    Bovine viral diarrhoea virus (BVDV), a member of the Pestivirus genus, is one of the most important pathogens of dairy cattle; it can cause several clinical syndromes, ranging from subclinical to severe disease. The objectives of the current studies were to assess the effects of two biotypes of BVDV on sperm attachment to the zona pellucida (ZP) of oocytes and on fertilization rate in bovine in vitro fertilization (IVF). In two experiments, sperm at two concentrations (10⁵ and 10⁶/mL) and oocytes were incubated with 10⁶ TCID₅₀/mL cythopatic (CP) or noncythopatic (NCP) BVDV. In the first experiment, with the lower sperm concentration (10⁵/mL), male and female gametes were infected with CP or NCP BVDV, whereas in the second experiment, the sperm concentration was 10⁶/mL, and sperm and oocytes were also infected with CP or NCP BVDV. The number of sperm attached to the ZP and the fertilization rate were evaluated with fluorescence microscopy on the ZP of fertile and infertile oocytes. In the first experiment, compared to the control group (n = 97), oocytes infected with CP BVDV and incubated at the lower (10⁵/mL) sperm concentration positively affected sperm attachment (n = 123) to the ZP of fertile oocytes (P < 0.05). In comparison with the control group (n = 115), sperm infected with CP BVDV negatively affected sperm binding (n = 93) to the ZP of infertile oocytes (P < 0.05). In the second experiment (10⁶ sperm/mL), for both fertile and infertile oocyte groups, sperm attachment in the control group was very high and deemed uncountable. However, in treated groups, the number of sperm attached to the ZP was countable. Only sperm infected with CP BVDV negatively affected sperm binding capacity (n = 81) to the ZP of fertile oocytes (P < 0.05). Although CP and NCP BVDV significantly reduced the fertilization rate of oocytes incubated with a higher sperm concentration, with the lower sperm concentration, only NCP BVDV significantly diminished

    Viruses play a key role in the complex aetiology of bovine respiratory disease (BRD). Bovine viral diarrhoea virus 1 (BVDV-1) is widespread in Australia and has been shown to contribute to BRD occurrence. As part of a prospective longitudinal study on BRD, effects of exposure to BVDV-1 on risk of BRD in Australian feedlot cattle were investigated. A total of 35,160 animals were enrolled at induction (when animals were identified and characteristics recorded), held in feedlot pens with other cattle (cohorts) and monitored for occurrence of BRD over the first 50days following induction. Biological samples collected from all animals were tested to determine which animals were persistently infected (PI) with BVDV-1. Data obtained from the Australian National Livestock Identification System database were used to determine which groups of animals that were together at the farm of origin and at 28days prior to induction (and were enrolled in the study) contained a PI animal and hence to identify animals that had probably been exposed to a PI animal prior to induction. Multi-level Bayesian logistic regression models were fitted to estimate the effects of exposure to BVDV-1 on the risk of occurrence of BRD. Although only a total of 85 study animals (0.24%) were identified as being PI with BVDV-1, BVDV-1 was detected on quantitative polymerase chain reaction in 59% of cohorts. The PI animals were at moderately increased risk of BRD (OR 1.9; 95% credible interval 1.0-3.2). Exposure to BVDV-1 in the cohort was also associated with a moderately increased risk of BRD (OR 1.7; 95% credible interval 1.1-2.5) regardless of whether or not a PI animal was identified within the cohort. Additional analyses indicated that a single quantitative real-time PCR test is useful for distinguishing PI animals from transiently infected animals. The results of the study suggest that removal of PI animals and/or vaccination, both before feedlot entry, would reduce the impact of BVDV-1 on BRD risk

    Studies covering all aspects of bovine viral diarrhoea virus (BVDV) have been conducted in several countries in Europe, Asia and America. In southern Africa, more information is required about the nature of BVDV infection, the prevalence of different strains and the economic importance of the disease. The presence of BVDV in southern Africa has been known since the early 1970s through serological surveys but few reports confirming its presence by virus isolation and correlation with clinical disease are available. Specimens (n = 312) collected in 1998/99, from live and dead cattle from different farming systems, were obtained from private practitioners, feedlot consultants and abattoirs throughout the country. Specimens (n = 37) from African buffaloes (Syncerus caffer) in the Kruger National Park were also included. All specimens were processed for virus isolation in cell culture with confirmation by means of immunofluorescent antibody tests and some also by means of an antigen capture ELISA. BVDV was isolated from 15 (4.7%) cattle and were all noncytopathic biotypes. BVDV was not detected in 37 lymph nodes obtained from buffaloes in the Kruger National Park. Of the clinical signs in cattle from which virus were isolated, respiratory signs was the most frequent (10/15), followed by diarrhoea (5/15). Abortion, congenital malformations, haemorrhagic diarrhoea and poor growth were also included as criteria for selection of animals for specimen collection, but no BVD viruses were isolated from cattle manifesting these clinical signs.

    In April 1994, Vibrio metschnikovii was isolated from five infants with watery diarrhoea in Arequipa, Peru, as part of a passive cholera surveillance system. The children ranged in age from 11 to 20 months and had acute diarrhoea, with two cases showing moderate dehydration. Two children also had traces of blood in liquid stool. The children were seen at two different hospitals, and no evidence of a common source of infection was found. No additional V. metschnikovii isolates were identified in the remaining surveillance period that covered the rest of 1994 and 1995. However, stool samples were not screened for enteric pathogens other than vibrios. V. metschnikovii strains isolated from stool samples produced opaque and translucent colonies on agar plates, suggesting capsular material. All isolates were resistant to ampicillin, erythromycin and streptomycin. Plasmid analysis revealed a common 200-kb plasmid in isolates from all cases and an additional 2.7-kb plasmid in three of the isolates. Ribotyping of each isolate after restriction with BglI and HindIII endonucleases demonstrated identical ribotyping patterns. The cases reported suggest that V. metschnikovii may be associated with diarrhoea in man by mechanisms so far unknown.

    In dogs with idiopathic acute haemorrhagic diarrhoea syndrome (AHDS), a serious loss of intestinal mucosal barrier integrity occurs. However, the incidence of bacterial translocation in dogs with idiopathic AHDS is not known. Thus, the objectives of this prospective study were to identify the incidence of bacteraemia, to evaluate the frequency of septic events and the influence of bacteraemia on various clinical and laboratory parameters, duration of hospitalisation and survival of dogs with idiopathic AHDS. The study included 87 dogs with idiopathic AHDS. Twenty-one healthy dogs served as control group. To evaluate clinical significance of bacterial translocation, blood culture results were compared between patients and controls. Clinical and laboratory parameters were compared between patients with positive and negative blood cultures. There was no significant difference in either incidence of bacteraemia between patients with idiopathic AHDS (11 per cent) and controls (14 per cent) or in severity of clinical signs, laboratory parameters, duration of hospitalisation or mortality between blood culture-positive and culture-negative dogs with idiopathic AHDS. The results of this study suggest that the incidence of bacteraemia in dogs with idiopathic AHDS is low and not different from that of healthy control dogs. Bacteraemia does not influence the clinical course or survival and thus antibiotic treatment is not indicated to prevent sepsis.

    A programme to eradicate bovine viral diarrhoea was launched in Switzerland in 2008 with the aim of eradicating the causal virus. During the first year of the programme, the entire population of 1.6 million cattle were tested for the presence of the virus; in the following three years an additional 1.8 million calves were tested. The complexity of information generated during the eradication programme, together with a tight schedule, made computerised data management a necessity. To organise, coordinate and supervise the programme, extensions were made to the computerised information system ISVet, of the Swiss Veterinary Service, which provides automated documents for both the Veterinary Service and private veterinarians. Specific data are accessible by user groups via the BVD-Web platform, ISVet and the Swiss animal movement database. The functionalities of the structure and the reports needed to control the progress of the programme are described in detail. The authors also discuss the major advantages, disadvantages and pitfalls when planning an eradication programme using a national centralised database over a distributed computer network.

    The efficacy of vancomycin in pseudomembranous colitis was assessed in a prospective randomised controlled trial. Forty-four patients with postoperative diarrhoea were allocated to five days' treatment with either 125 mg vancomycin six-hourly or a placebo. Sixteen patients had high titres of the neutralised faecal toxin characteristic of pseudomembranous colitis; nine received vancomycin and seven placebo. At the end of treatment faecal toxins were present in one patient given vancomycin compared with five of the controls. Vancomycin caused the disappearance of Clostridum difficile from the stool in all except one patient, whereas toxicogenic strains of Cl difficile persisted in all but one of the controls. Histological evidence of psuedomembranous colitis had disappeared by the end of treatment in six out of seven patients given vancomycin compared with only one out of seven patients given vancomycin compared with only one out of five patients given placebo. In patients with faecal toxins bowel habit had returned to normal in seven of the vancomycin group compared with only one of the controls, but there was no significant difference in clinical response among patients without faecaal toxins. The results suggest that vancomycin eliminates toxin-producing Cl difficile from the colon and is associated with rapid clinical and histological improvement in patients with pseudomembranous colitis.

    Background Diarrhoeal diseases constitute a major public health problem, particularly in the developing world, where the rate of mortality and morbidity is very high. The purpose of this study was to conduct a 2 years and 3 months study in order to determine the prevalence of five enteropathogen diarrheogenic agents in Mexico City. Methods Faecal samples were obtained from 300 Mexican children diagnosed as positive for diarrhoea, aged > 2 to < 12 years old, and from 80 children matched for age but with no symptoms of the disease (control group). Two multiplex PCR were used to detect Escherichia coli, Salmonella spp., and Shigella spp. In addition, the two protozoan parasites Entamoeba histolytica/Entamoeba dispar and Giardia intestinalis were detected by conventional methods. Results All diarrhoeal samples were positive for one or more enteropathogens. The most common enteropathogens in diarrhoeal samples were E. histolytica/E. dispar (70.3%), Salmonella (ohio 28.3%; typhimurium 16.3%; infantis 8%; anatum 0.6%; Newport 0.3%), G. intestinalis (33%), E. coli (ETEC 13.3%; EPEC 9.3%; VTEC 8.6%; EIEC 1%) and Shigella spp. (flexneri 1.6%, sonnei 1%). Infections by two (24%) three (16%) and four (12%) pathogens were observed. Conclusion This study revealed that 52% of the patients were infected by more than one enteropathogen, notably E. histolitica/E. dispar and Salmonella ohio. These results are useful for clinicians to improve the empiric treatment used in such cases. PMID:18162140

    Travellers' diarrhoea (TD) remains the most frequent health problem encountered by visitors to the (sub)tropics. Traditional stool culture identifies the pathogen in only 15% of cases. Exploiting PCR-based methods, we investigated TD pathogens with a focus on asymptomatic travellers and severity of symptoms. Pre- and post-travel stools of 382 travellers with no history of antibiotic use during travel were analysed with a multiplex quantitative PCR for Salmonella, Yersinia, Campylobacter, Shigella, Vibrio cholerae and five diarrhoeagenic Escherichia coli: enteroaggregative (EAEC), enteropathogenic (EPEC), enterotoxigenic (ETEC), enterohaemorrhagic (EHEC) and enteroinvasive (EIEC). The participants were categorized by presence/absence of TD during travel and on return, and by severity of symptoms. A pathogen was indentified in 61% of the asymptomatic travellers, 83% of those with resolved TD, and 83% of those with ongoing TD; 25%, 43% and 53% had multiple pathogens, respectively. EPEC, EAEC, ETEC and Campylobacter associated especially with ongoing TD symptoms. EAEC and EPEC proved more common than ETEC. To conclude, modern methodology challenges our perception of stool pathogens: all pathogens were common both in asymptomatic and symptomatic travellers. TD has a multibacterial nature, but diarrhoeal symptoms mostly associate with EAEC, EPEC, ETEC and Campylobacter.

    Eight colostrum-deprived calves aged 8-12 weeks were inoculated intranasally with a non-cytopathic strain of bovine viral diarrhoea virus (BVDV) genotype-1 and the effects on the hepatic immune response were studied. Two calves were sacrificed at each of 3, 6, 9 and 14 days post-inoculation (dpi) and two uninoculated animals were used as negative controls. BVDV was detected in hepatic macrophages and monocytes from 3 to 14dpi and in Küpffer cells (KCs) from 6 to 14dpi. Increases in the numbers of MAC387(+) KCs and monocytes, but not interstitial macrophages, differentiated by morphological features, were evident in the liver following inoculation with BVDV. There was a substantial increase in the number of monocytes positive for tumour necrosis factor (TNF)-α, but only small increases in the numbers of TNF-α(+) KCs and interstitial macrophages and interleukin (IL)-6(+) monocytes, KCs and interstitial macrophages. There was an increase in the number of interstitial CD3(+) T lymphocytes in the liver, but no substantial changes in the numbers of circulating CD3(+) T lymphocytes, interstitial or circulating CD4(+) or CD8(+) T lymphocytes, or CD79αcy(+) B lymphocytes. Serum haptoglobin and serum amyloid A increased transiently at 12dpi. Upregulation of some pro-inflammatory cytokines by hepatic macrophages is evident in subclinical acute BVDV type 1 infection in calves.

    The hematological and clinical chemistry profile for children aged 6 months to 5 years with acute diarrhoea was measured in a double blind clinical trial. Subjects were randomized to the study group (N = 44) given a bioactive polyphenol dietary supplement in oral rehydration solution (ORS) or to the control group (N = 41) given distilled water as a placebo in ORS twice daily for up to 4 days. All subjects received 10 mg zinc daily for the 4 days in the study. Venous blood was collected for complete blood count, electrolytes, liver function, and creatinine upon enrollment (baseline) and at the end of 4 days (end of study); mean values were compared by 95% confidence intervals. Overall, blood factors measured either remained the same over the 4 days or increased or decreased at the same levels between the two groups during the study period. All values were within accepted ranges for paediatric subjects except serum AST (SGOT), where the mean value of the study group approached the upper bound of the range on day 4 but was comparable to the value of the control group. Consumption of this supplement twice daily for 4 days is safe for children and infants. PMID:26435718

    Globally, the eradication of bovine viral diarrhoea virus (BVDV) is still in its infancy, but eradication has been, or is being, adopted by several countries or regions. Comparisons between countries' schemes allow others to assess best practice, and aggregating published results from eradication schemes provides greater statistical power when analysing data. Aggregating data requires that results derived from different testing schemes be calibrated against one another. The authors aimed to evaluate whether relationships between published BVDV test results could be created and present the outcome of a systematic literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The results are tabulated, providing a summary of papers where there is potential cross-calibration and a summary of the obstacles preventing such data aggregation. Although differences in measuring BVDV present barriers to academic progress, they may also affect progress within individual eradication schemes. The authors examined the time taken to retest following an initial antibody BVDV test in the Scottish eradication scheme. The authors demonstrate that retesting occurred quicker if the initial not negative test was from blood rather than milk samples. Such differences in the response of farmers/veterinarians to tests may be of interest to the design of future schemes.

    Bovine viral diarrhoea virus (BVDV) causes persistent infections by infecting the fetus of susceptible animals during gestation. These persistently infected (PI) animals are important sources of infection. On the contrary, transiently infected (TI) animals are believed to be less important, but transient infections with a severe BVDV-2 strain can spread explosively. To assess the importance of TI cattle in the epidemiology of BVDV, two experimental infections were performed to determine basic reproduction ratios (R0). In each experiment three calves were infected via intranasal inoculation and housed together with seven susceptible animals. Two strains isolated in Belgium were used, a virulent BVDV-1b and a virulent BVDV-2a field isolate, resulting in an R0 of 0.25 (95% CI 0.01; 1.95) and 0.24 (95% CI 0.01; 2.11), respectively. A PI animal was then introduced to the remaining uninfected animals and produced an R of +∞ (95% CI 1.88; +∞). These results support the suggestion that TI animals, compared to PI animals, contribute only a limited amount to BVDV spread. Additionally, the severe clinical symptoms observed in the field with these isolates could not be reproduced during these experiments, suggesting that other factors besides strain virulence influence the clinical manifestations evoked by BVDV.

    Previous studies have shown that bovine viral diarrhoea virus type 1 (BVDV-1) subtype b is predominantly circulating in Indian cattle. During testing for exotic pestiviruses between 2007 and 2010, BVDV-2 was identified by real time RT-PCR in two of 1446 cattle blood samples originating from thirteen states of India. The genetic analysis of the isolated virus in 5' UTR, N(pro), entire structural genes (C, E(rns), E1 and E2), nonstructural genes NS2-3 besides 3' UTR demonstrated that the nucleotide and amino acid sequences showed highest similarity with BVDV-2. The entire 5' and 3' UTR consisted of 387 and 204 nucleotides, respectively, and an eight nucleotide repeat motif was found twice within the variable part of 3' UTR that may be considered as a characteristic of BVDV-2. The phylogenetic analysis revealed that the cattle isolate and earlier reported goat BVDV-2 isolate fall into separate clades within BVDV-2a subtype. Antigenic typing with monoclonal antibodies verified the cattle isolate also as BVDV-2. In addition, cross-neutralization tests using antisera raised against Indian BVDV strains circulating in ruminants (cattle, sheep, goat and yak) displayed significant antigenic differences only between BVDV-1 and BVDV-2 strains. This is the first identification of BVDV-2 in Indian cattle that may have important implications for immunization strategies and molecular epidemiology of BVD.

    The genetic variation of bovine viral diarrhoea virus (BVDV) was studied by comparative nucleotide sequence analysis of 26 Italian field strains collected during the period 1995-2000 in 18 cattle herds. A fragment within the 5'-untranslated region (UTR) was sequenced directly from gel-purified products obtained by reverse transcription polymerase chain reaction. BVDV-1b (n=14), -1c (n=1), -1d (n=1) and BVDV-2 (n=2) strains have been isolated. Most herds were infected by BVDV-1b. Pairwise similarity and cluster analysis of the remaining BVDV-1 isolates (n=8) did not provide a clear-cut assignation to defined BVDV-1 groups. This is the first time that a BVDV-2 isolation was reported in Italy. Among BVDV-2 reference strains, Italian BVDV-2 isolates showed the highest sequence similarity with the CD87 strain. Both BVDV-2 strains were isolated in two healthy animals from different herds. The 5'-UTR sequence of one of the two BVDV-2 strains was identical to a German BVDV field strain. Complete nucleotide homology was found only among BVDV strains isolated from the same herd, showing a herd-specific clustering. Moreover, 99.6% homology was observed between strains from herds linked by livestock trade. Despite the small number of BVDV isolates analysed, it revealed a high level of genetic diversity among Italian field BVDV strains.

    Recently, bovine viral diarrhoea virus type 2c (BVDV-2c) was responsible for a severe outbreak in cattle in northern Europe. Here, we present the results of an epidemiological survey for pestiviruses in ruminants in southern Italy. Pooled serum samples were obtained from 997 bovine, 800 ovine, 431 caprine and eight bubaline farms, and pestiviral RNA was detected by molecular methods in 44 farms consisting of 16 cattle and one buffalo herds and of 21 sheep and six goat flocks. Twenty-nine and 15 farms were infected by BVDV-1 and BVDV-2 strains, respectively. BVDV-1 strains were recovered mainly from cattle and were heterogeneous, belonging to the subtypes 1b, 1u, 1e, 1g and 1h. In contrast, all BVDV-2 viruses but two were detected in sheep or goats and were characterized as BVDV-2c by sequence analysis of 5'UTR. These strains displayed high genetic identity to BVDV-2c circulating in cattle in northern Europe and were more distantly related to a BVDV-2c isolate recovered from a cattle herd in southern Italy more than 10 years before. The circulation of a BVDV-2c in small ruminants suggests the need for a continuous surveillance for the emergence of pestivirus-induced clinical signs in southern Italian farms.

    Seventy-eight bovine viral diarrhoea viruses (BVDV) recently collected in Austria, France, Hungary, Italy, Slovakia, Spain and UK were genetically typed in the 5'-untranslated (5'UTR) and autoprotease (Npro) regions of the pestivirus genome. Seventy-six of the isolates were BVDV-1 and two French isolates were of the BVDV-2 genotype. Phylogenetic analysis of the 5'UTR (245 nt), including additional BVDV-1 sequences from USA, Canada, Germany, New Zealand, Mozambique and Sweden, taken from GenBank and from our previous works, indicated that these viruses were clustered not only into the two generally accepted groups (BVDV-1a-"NADL like" and BVDV-1b-"Osloss like"), but altogether into 11 phylogenetic groups. Similar clustering was observed with Npro region sequences (385 nt) and the highest bootstrap values (over 95%) were obtained by phylogeny combining 5'UTR and Npro sequences. Some associations between the genetic grouping and the origin of the isolates were apparent, probably reflecting historical trade contacts. Considering the variability of isolates it is recommended that diagnostic PCR primers should be re-examined to ensure coverage of all BVDV-1 groups. The genogroups were less clearly differentiated by monoclonal antibody typing, suggesting significant antigenic similarities within the BVDV-1 genotype.

    Following the first official report of a clinically severe outbreak of bovine viral diarrhoea disease occurring in a farm in northern Italy, which had originated from the use of a live vaccine contaminated with a strain of BVD genotype II virus, a retrospective study on the prevalence of BVDV genotypes in Italy became highly relevant. For this purpose, the genotype of 78 BVDV-positive specimens, obtained in 1998-1999 from dairy cattle in an area near to where the outbreak occurred, was characterized by PCR technology. Two sets of primers, spanning the 5' UTR of BVDV genome, were used sequentially in a first round of RT-PCR, performed on viral RNA extracted directly from 15 clinical samples and 63 BVDV-infected cell-culture fluids; a second PCR assay followed to selectively amplify only BVDV genotype II. All the viruses under study were characterized as BVDV genotype I. As well as contributing to a better understanding of the prevalence of BVDV genotypes in the field, the results of the present study illustrate the possibility that novel BVDV strains can emerge in susceptible animals through the use of contaminated immunobiological products for bovine use.

    Beginning in April 2006, 41 farms were recruited onto a pilot Bovine viral diarrhoea virus (BVDV) eradication programme across the south of England with the majority of study herds concentrated in Somerset. Each herd was assessed and where relevant cleared of persistently infected (PI) animals. Seven farms dropped out before whole herd screening could be performed. Of the remaining 34 farms, 20 (59 per cent) were classified as infected although two of these were initially misclassified as BVDV-free. Over the course of three years, 61 PIs were identified across 16 of the 20 infected farms. 72 per cent of PIs indentified on the first herd test were below two years of age. PI prevalence ranged from 0.2 to 3.1 per cent of infected herds and was highest in herds that did not vaccinate. By the end of 2009, 24/34 (71 per cent) of study farms were BVDV-free while 10 (29 per cent) remained infected.

    Intestinal function is poorly defined in patients with HIV infection. Absorptive capacity and intestinal permeability were assessed using 3-O-methyl-D-glucose, D-xylose, L-rhamnose, and lactulose in 88 HIV infected patients and the findings were correlated with the degree of immunosuppression (CD4 counts), diarrhoea, wasting, intestinal pathogen status, and histomorphometric analysis of jejunal biopsy samples. Malabsorption of 3-O-methyl-D-glucose and D-xylose was prevalent in all groups of patients with AIDS but not in asymptomatic, well patients with HIV. Malabsorption correlated significantly (r = 0.34-0.56, p < 0.005) with the degree of immune suppression and with body mass index. Increased intestinal permeability was found in all subgroups of patients. The changes in absorption-permeability were of comparable severity to those found in patients with untreated coeliac disease. Jejunal histology, however, showed only mild changes in the villus height/crypt depth ratio as compared with subtotal villus atrophy in coeliac disease. Malabsorption and increased intestinal permeability are common in AIDS patients. Malabsorption, which has nutritional implications, relates more to immune suppression than jejunal morphological changes. PMID:8549936

    Diarrhoeal disease is still considered a major cause of morbidity and mortality among children. Among diarrhoeagenic agents, Shigella should be highlighted due to its prevalence and the severity of the associated disease. Here, we assessed Shigella prevalence, drug susceptibility and virulence factors. Faeces from 157 children with diarrhoea who sought treatment at the Children's Hospital João Paulo II, a reference children´s hospital in Belo Horizonte, state of Minas Gerais, Brazil, were cultured and drug susceptibility of the Shigella isolates was determined by the disk diffusion technique. Shigella virulence markers were identified by polymerase chain reaction. The bacterium was recovered from 10.8% of the children (88.2% Shigella sonnei). The ipaH, iuc, sen and ial genes were detected in strains isolated from all shigellosis patients; set1A was only detected in Shigella flexneri. Additionally, patients were infected by Shigella strains of different ial, sat, sen and set1A genotypes. Compared to previous studies, we observed a marked shift in the distribution of species from S. flexneri to S. sonnei and high rates of trimethoprim/sulfamethoxazole resistance.

    The strategies used and the results obtained in Orkney's bovine viral diarrhoea virus (BVDV) eradication programme over eight years (2001 to 2008) are presented and discussed. The venture was undertaken by local veterinary practices and the Orkney Livestock Association (OLA) with the financial support of the Orkney Islands Council. Participation is voluntary; the programme comprises screening of youngstock, a whole-herd test if required, elimination of persistently infected animals and strict biosecurity measures and/or vaccination. BVDV-free herds are certified, and certification is updated annually by retesting the youngstock. The programme aims to minimise economic losses, thereby increasing the competitiveness of the Orcadian cattle industry and to improve animal health and welfare by eliminating virus circulation. Information from databases of the Scottish Agricultural College, Biobest Laboratories and OLA show that despite a significant reduction in the overall prevalence of BVDV on Orkney during the initial stages of the eradication programme, there has been little progress made since 2006 and that some difficulties have been encountered, with herd BVDV breakdowns following initial eradication. These results highlight the need for continued motivation of farmers, strict application of biosecurity measures and/or systematic vaccination of all seronegative breeding animals.

    We evaluated a three-step algorithm for laboratory diagnosis of Clostridium difficile-associated diarrhoea (CDAD). First, stool specimens were screened using an EIA test for glutamate dehydrogenase detection. Screen-positive specimens were tested by a rapid cytotoxintoxin A/B assay and subjected to stool culture. All cultures positive for C. difficile underwent toxigenic culture. The results showed that toxigenic culture allowed us to recover 37/156 (24.4%) stool samples harbouring toxigenic C. difficile that would have been missed by using faecal cytotoxin assay alone. This determined an increase in infection prevalence of 4.2% (from 11.4% to 15.6 %). Furthermore, to characterize the clinical Clostridium difficile isolates and the distribution of PCR ribotypes circulating in the San Carlo Borromeo hospital, molecular typing using semi-automated repetitive-sequence-based PCR (rep- PCR) and PCR ribotyping, and an evaluation of the antibiotic resistance were also performed. Among them, 71 indistinguishable strains were detected by rep-PCR and 83 by PCR-ribotyping revealing C. difficile outbreaks in our hospital. A total of 6 different ribotypes were obtained by PCR ribotyping. The most frequent ribotype was 018 (88.2%) that also showed resistance to moxifloxacin. In one case, uncommon PCR ribotype 186 was also identified.

    1988-10-01

    The molecular features of bovine viral diarrhoea virus (BVDV), a member of the Pestivirus genus currently classified in the Togaviridae, were examined for characteristics resembling those of the Flaviviridae family. Like flaviviruses, BVDV possesses a single-stranded RNA genome (approx. 4.3 x 10(6) Mr) deficient in a 3' poly(A) tract. This RNA has a single open reading frame spanning the length of the genome in the viral RNA sense (positive polarity), implying an expression strategy involving the processing of a precursor polyprotein. With the exception of several short but significant stretches of identical amino acids within two non-structural proteins, no extended regions of nucleotide or amino acid sequence homology between BVDV and representatives of three serological subgroups of mosquito-borne flaviviruses were noted. However, comparison of the organization of protein-coding domains along the genomes and the hydropathic profiles of amino acid sequences revealed pronounced similarities. It is proposed that Pestivirus, of which BVDV is the prototype member, should no longer be grouped in the Togaviridae family, but rather be considered a genus of non-arthropod-borne viruses within the Flaviviridae.

    To determine if loperamide is effective and safe in treating watery diarrhoea, we randomly assigned 50 adult expatriates in Bangladesh with more than three unformed stools in the previous 24 hours and illness of less than 72 hours to receive loperamide or a placebo. On entry into the five day study patients took two capsules (one loperamide capsule = 2 mg) and one after each unformed stool up to a maximum of eight per day. The groups did not significantly differ in pretreatment features or pathogens identified. Mean number of stools on study day 1 was 2.6 in the loperamide group and 4.0 in the placebo group (p = 0.035); on day 2 it was 1.3 versus 3.4 (p less than 0.001). Differences in stool frequencies during the final three study days, or proportion of patients with cramps, nausea, or vomiting on any study day, were not significant. No serious side effects occurred in either group. We conclude that loperamide, by decreasing stool frequency during the early part of illness, may have a role in the symptomatic treatment of this self-limiting disease. PMID:2653972

    A non-seasonal diarrhoeal episode in the Jordan Valley occurred over a 2-month period, during which no traditional enteropathogens were detected by the health authority laboratories. A total of 17 diarrhoeal stool specimens from infants, young children and adults were randomly collected and delivered to our laboratories to investigate the presence of unusual aetiological agents. Stools were examined for parasites, ova, viruses and cultured for bacterial pathogens. A multiplex polymerase chain reaction was developed to investigate the involvement of diarrhoeagenic Escherichia coli in this episode. Recognised pathogenic organisms were detected in 8 out of 17 of the diarrhoeatic patients, one patient of whom had a mixed infection with two agents. Rotavirus, enteroinvasive E. coli (EIEC), enteropathogenic E. coli (EPEC), and enterotoxigenic E. coli (ETEC) were found to be associated with the diarrhoea. EIEC was the most common enteropathogen detected (4 out of 17) followed by rotavirus (3 out of 17). One of the EIEC isolates detected in one patient was associated with rotavirus. The clinical features of the diarrhoeatic patients were remarkably similar, regardless of aetiology. This study reveals the identity of pathogenic agents that are not detected by traditional methods employed by the health authority laboratories, which emphasise the urgent need for developing the current diagnostic techniques.

    Diarrhoeal disease is still considered a major cause of morbidity and mortality among children. Among diarrhoeagenic agents, Shigella should be highlighted due to its prevalence and the severity of the associated disease. Here, we assessed Shigella prevalence, drug susceptibility and virulence factors. Faeces from 157 children with diarrhoea who sought treatment at the Children's Hospital João Paulo II, a reference children´s hospital in Belo Horizonte, state of Minas Gerais, Brazil, were cultured and drug susceptibility of the Shigella isolates was determined by the disk diffusion technique. Shigella virulence markers were identified by polymerase chain reaction. The bacterium was recovered from 10.8% of the children (88.2% Shigella sonnei). The ipaH, iuc, sen and ial genes were detected in strains isolated from all shigellosis patients; set1A was only detected in Shigella flexneri. Additionally, patients were infected by Shigella strains of different ial, sat, sen and set1A genotypes. Compared to previous studies, we observed a marked shift in the distribution of species from S. flexneri to S. sonnei and high rates of trimethoprim/sulfamethoxazole resistance. PMID:23440111

    One in five American children grows up in poverty. Childhood poverty has far-reaching adverse impacts on cognitive, social and emotional development. Altered development of neurocircuits, subserving emotion regulation, is one possible pathway for childhood poverty's ill effects. Children exposed to poverty were followed into young adulthood and then studied using functional brain imaging with an implicit emotion regulation task focused. Implicit emotion regulation involved attention shifting and appraisal components. Early poverty reduced left dorsolateral prefrontal cortex recruitment in the context of emotional regulation. Furthermore, this emotion regulation associated brain activation mediated the effects of poverty on adult task performance. Moreover, childhood poverty also predicted enhanced insula and reduced hippocampal activation, following exposure to acute stress. These results demonstrate that childhood poverty can alter adult emotion regulation neurocircuitry, revealing specific brain mechanisms that may underlie long-term effects of social inequalities on health. The role of poverty-related emotion regulatory neurocircuitry appears to be particularly salient during stressful conditions.

    Developmental prosopagnosia (DP) is defined by severe face recognition problems resulting from a failure to develop the necessary visual mechanisms for processing faces. While there is a growing literature on DP in adults, little has been done to study this disorder in children. The profound impact of abnormal face perception on social functioning and the general lack of awareness of childhood DP can result in severe social and psychological consequences for children. This review discusses possible etiologies of DP and summarizes the few cases of childhood DP that have been reported. It also outlines key objectives for the growth of this emerging research area and special considerations for studying DP in children. With clear goals and concerted efforts, the study of DP in childhood will be an exciting avenue for enhancing our understanding of normal and abnormal face perception for all age groups.

    The study obtained information using quantitative and qualitative techniques, on key home management practices of common childhood illnesses in Community-Integrated Management of Childhood Illnesses (C-IMCI) and non-C-IMCI implemented local government areas (LGAs) in Osun state, to determine if any differences existed between them. Data analysis was done using Epi-info version 6.0 for the quantitative survey and content analysis method for the qualitative survey. Findings revealed better key home management practices in the C-IMCI compliant LGA than in the non-CIMCI compliant LGA. The proportion of caregivers who gave appropriate home treatment for malaria during their children's illnesses differed significantly (p = 0.000) between the two LGAs. Similarly, caregivers from the compliant LGA demonstrated better treatment practices for diarrhoea and cough. Community Resource Persons (CORPs) were the major source of information on these key practices in the compliant LGA; while in the non-compliant LGA, the traditional healers, elders, and to a lesser extent, health workers gave information. Findings showed that the C-IMCI strategy improved caregivers' home management of common childhood illnesses.

    Our purpose was to determine direct production losses (milk loss, premature voluntary culling and reduced slaughter value, mortaliy loss, and abortion and reproductive loss) and treatmetn costs (veterinary services, medication cost, and extra farm labour cost) due to four infectious diseases in the maritime provinces of Canada: bovine viral diarrhoea (BVD), enzootic bovine leukosis (EBL), Johne's Disease (JD), and neosporosis. We used a partial-budget model, and incorporated risk and sensitivity analyses to identify the effects of uncertainty on costs. Total annual costs for an average, infected, 50 cow herd were: JD$ 2472; BVD$ 2421; neosporosis $ 2304; EBL$ 806. The stochastic nature of the proportion of infected herds and prevalence of infection within a herd were used to estimate probability distributions for these ex post costs. For all diseases, these distributions were right skewed. A sensitivity analysis showed the largest effect on costs was due to milk yield effects. For example, changing milk production loss from 0 to 5% for BVD increased the costs for the disease by 266%.

  10. Impact of changes in antibiotic policy on Clostridium difficile-associated diarrhoea (CDAD) over a five-year period in a district general hospital.

    The impact of changes in antibiotic policy on Clostridium difficile-associated diarrhoea (CDAD), over a five-year period between 1995 and 2000, were studied in the Preston Acute Hospitals Trust. In 1996 the policy was changed in the Preston Acute Hospitals Trust from cefotaxime to ceftriaxone for initial treatment of severe sepsis or pneumonia in medical patients. Over the next nine months the average number of patients with C. difficile toxin-positive stools per quarter increased from 16 to 39. The predicted use of ceftriaxone exceeded by 65% an estimate based on prior use of cefotaxime. A policy of restricted duration of ceftriaxone was introduced, and although this reduced usage by over 50%, CDAD continued at an average of 9.2 cases per month, despite withdrawal of oral cephalosporins in December 1998. In August 1999 levofloxacin was substituted for ceftriaxone in the policy. The incidence of CDAD fell progressively to five cases per month by 2000. It would appear that a short (typically three dose) course of third-generation cephalosporin poses a similar risk for CDAD as a more prolonged course. The six-month delay in the decline of CDAD after virtual withdrawal of cephalosporins may reflect a slowly diminishing environmental reservoir.

    In Tlaxcala, Mexico, 80% of the children who died from diarrhoea or acute respiratory infections (ARI) in 1992-1993 received medical care; in more than 70% of cases it was provided by a private general practitioner (GP). The present study evaluated the quality of case management by private and public GPs to children under five years of age with diarrhoea and ARI. During the clinical observation, the treatment and counselling given to the mother were assessed with the WHO guidelines as reference standard. A total of 41 private and 40 public GPs were evaluated for the management of diarrhoea, and 59 private and 40 public GPs for the management of ARI. For diarrhoea, half of the private GPs gave inadequate rehydration therapy, 63% gave incorrect advice on diet, 66% and 49% made an incorrect correct decision in the prescription of antimicrobial and symptomatic drugs, respectively. Public GPs generally performed better in diarrhoea management: 7% gave inadequate rehydration therapy, 13% gave wrong advice on diet, 3% made a wrong decision in the prescription of symptomatic drugs and 28% gave a wrong decision in antimicrobial prescription. In the management of ARI, 66% and 58% of private GPs made a wrong decision in the prescription of antimicrobial and symptomatic drugs, respectively, compared to 30% and 20% of public GPs, respectively. Counselling to the mother given by both private and public GPs was considered inadequate in most cases of diarrhoea and ARI. These results clearly show that private doctors, as important providers of medical care, need to be included in the strategies to improve the quality of care of children with diarrhoea and ARI. Future research needs to address the determinants of the clinical practice of private doctors in countries like Mexico.

    The term tylosin-responsive diarrhoea (TRD) is used for canine recurrent diarrhoea cases for which no underlying cause can be found after extensive diagnostic investigations, but which show a response to the antibiotic tylosin in a few days. The objective of this prospective, one-arm longitudinal trial was to assess the effects of oral tylosin administration on the faecal levels of potentially probiotic bacteria, such as Enterococcus spp. and lactic acid bacteria (LAB), in dogs with TRD. This trial included 14 client-owned suspected TRD dogs that were on tylosin treatment and had firm faeces. Treatment was then terminated and dogs were followed up for up to 2 months to determine the recurrence of diarrhoea. Once diarrhoea started, dogs received tylosin (orally, 25 mg/kg, once daily for 7 days). At the end of the treatment period, stools were firm again in 11 dogs (TRD dogs); three dogs continued having diarrhoea and were excluded from the study. Faecal samples were collected at all three time-points for culture of LAB and enterococci. In TRD dogs, the colony counts of Enterococcus spp. (P = 0.003), LAB (P = 0.037), tylosin-resistant Enterococcus spp. (P <0.001) and LAB (P <0.001) were significantly higher when the dogs were on tylosin treatment and had normal faecal consistency compared to when they had diarrhoea following discontinuation of tylosin. In conclusion, cessation of diarrhoea in TRD dogs with tylosin treatment could be mediated by selection of a specific lactic acid population, the Enterococcus spp., due to their potential probiotic properties.

  13. Prevention of unintentional childhood injury.

    2013-04-01

    Unintentional injury accounts for 40 percent of childhood deaths annually, most commonly from motor vehicle crashes. The proper use of child restraints is the most effective strategy to prevent injury or death. Motor vehicle restraint guidelines have recently been revised to an age-based system that delays the progression in type of restraint for most children. Strategies to prevent suffocation in children include using appropriate bedding, positioning babies on their backs to sleep, and removing items from the sleep and play environment that could potentially entrap or entangle the child. Fencing that isolates a swimming pool from the yard and surrounding area and "touch" adult supervision (i.e., an adult is in the water and able to reach and grab a child) have been shown to be most effective in preventing drownings. Swimming lessons are recommended for children older than four years. Poison prevention programs have been shown to improve prevention behavior among caregivers, but may not decrease poisoning incidence. Syrup of ipecac is not recommended. Smoke detector maintenance, a home escape plan, and educating children about how to respond during a fire emergency are effective strategies for preventing fire injuries or death. Fall injuries may be reduced by not using walkers for infants and toddlers or bunk beds for children six years and younger. Consistent helmet use while bicycling reduces head and brain injuries. Although direct counseling by physicians appears to improve some parental safety behaviors, its effect on reducing childhood injuries is uncertain. Community-based interventions can be effective in high-risk populations.

    The relationship between childhood maltreatment and future threats with weapons is unknown. We examined data from the nationally representative National Comorbidity Survey Replication (n = 5692) and conducted multiple logistic regression analyses to determine the association between childhood maltreatment and lifetime behavior of threatening others with a gun or other weapon. After adjusting for sociodemographic variables, physical abuse, sexual abuse, and witnessing domestic violence were significantly associated with threats made with a gun (adjusted odds ratios [AOR] ranging between 3.38 and 4.07) and other weapons (AOR ranging between 2.16 and 2.83). The greater the number of types of maltreatment experienced, the stronger the association with lifetime threats made to others with guns and any weapons. Over 94% of respondents who experienced maltreatment and made threats reported that the maltreatment occurred prior to threatening others with weapons. Prevention efforts that reduce exposure to maltreatment may reduce violent behavior in later life.

    Many childhood cancer survivors have psychosocial late effects. We studied the risks for cohabitation and subsequent separation. Through the Danish Cancer Register, we identified a nationwide, population-based cohort of all 1877 childhood cancer survivors born from 1965 to 1980, and in whom cancer was diagnosed between 1965 and 1996 before they were 20 years of age. A sex-matched and age-matched population-based control cohort was used for comparison (n=45,449). Demographic and socioeconomic data were obtained from national registers and explored by discrete-time Cox regression analyses. Childhood cancer survivors had a reduced rate of cohabitation [rate ratio (RR) 0.78; 95% confidence interval (CI): 0.73-0.83], owing to lower rates among survivors of both noncentral nervous system (CNS) tumors (RR 0.88; 95% CI: 0.83-0.95) and CNS tumors (RR 0.52; 95% CI: 0.45-0.59). Male CNS tumor survivors had a nonsignificantly lower rate (RR 0.47; 95% CI: 0.38-0.58) than females (RR 0.56; 95% CI: 0.47-0.68). The rates of separation were almost identical to those of controls. In conclusion, the rate of cohabitation was lower for all childhood cancer survivors than for the population-based controls, with the most pronounced reduction among survivors of CNS tumors. Mental deficits after cranial irradiation are likely to be the major risk factor.
