Full Text Available The present paper constitutes the second record of epimeletic behavior for the toninha, Pontoporia blainvillei. A toninha calf carcass was recovered at Enseada Beach, São Francisco do Sul, southern Brazil (26o13’S - 48o31’W on October 9, 2001. Its total length indicated that it was a neonate or a premature calf. The calf had many parallel scratches on it, which were freshly made and produced by adult teeth. There were scratches on the fin, flukes and flippers, and the position and size of the marks demonstrated the intention of the adult to rescue the calf. The anterior region of the body showed net marks, suggesting that the calf had been accidentally entangled. The epimeletic behavior evidenced by the tooth marks could have occurred during the entanglement and/or after its liberation, and we suggest that the causa mortis of the calf was drowning.

Full Text Available Economic performance of beef cattle operations can be severely hampered by acute calfhood diarrhea. Accordingly, a study was conducted at Bbalitvet to identify the causal agents, reduce clinical incidence, and increase body weight gain of newborn calves. One potential control is application of suitable vaccines to pregnant cows. The study was begun by identifying cases of diarrhea followed by isolation and identification of the causal agents in 12 beef cattle farms in West Java. A field trial was then designed for controlling calf diarrhea in such farms. Inactive vaccines Ecoli-Closvak polivalen were administered to pregnant cows to increase specific resistance of the newborn calves. At 2 months prepartum, 12 pregnant cows were assigned either to a vaccination or a placebo group, with a booster vaccination 3 weeks prior to parturition. Strict hygenic management was provided to both groups, and all calves were provided adequately with colostrum. Subjects were observed for 5 months, starting from the time of initial vaccination until the calves were 3 months of age. In the initial farm surveys, entero-pathogenic bacteria such as Escherichia coli serotype K99 and Clostridium perfringens type A and C were isolated and identified in fecal samples from 4 beef cattle farms in 3 districts (Garut, Tasikmalaya, Ciamis and 2 beef cattle farms in 2 districts (Tasikmalaya and Ciamis of West Java. In the vaccination trial, good immune responses to E. coli and C. perfringens alpha toxin measured by ELISA were observed. Application of effective control of calf diarrhea including vaccination and good livestock management showed good results. No death or signs of diarrhea were found in the new born calves up to 3 months of age. The rate of body weight gain was significantly higher in calves of vaccinated dams than in calves of non-vaccinated dams.

Full Text Available Abstract Background The aim of the present prospective study was to investigate whether a decision tree based on basic clinical signs could be used to determine the treatment of metabolic acidosis in calves successfully without expensive laboratory equipment. A total of 121 calves with a diagnosis of neonatal diarrhea admitted to a veterinary teaching hospital were included in the study. The dosages of sodium bicarbonate administered followed simple guidelines based on the results of a previous retrospective analysis. Calves that were neither dehydrated nor assumed to be acidemic received an oral electrolyte solution. In cases in which intravenous correction of acidosis and/or dehydration was deemed necessary, the provided amount of sodium bicarbonate ranged from 250 to 750 mmol (depending on alterations in posture and infusion volumes from 1 to 6.25 liters (depending on the degree of dehydration. Individual body weights of calves were disregarded. During the 24 hour study period the investigator was blinded to all laboratory findings. Results After being lifted, many calves were able to stand despite base excess levels below −20 mmol/l. Especially in those calves, metabolic acidosis was undercorrected with the provided amount of 500 mmol sodium bicarbonate, which was intended for calves standing insecurely. In 13 calves metabolic acidosis was not treated successfully as defined by an expected treatment failure or a measured base excess value below −5 mmol/l. By contrast, 24 hours after the initiation of therapy, a metabolic alkalosis was present in 55 calves (base excess levels above +5 mmol/l. However, the clinical status was not affected significantly by the metabolic alkalosis. Conclusions Assuming re-evaluation of the calf after 24 hours, the tested decision tree can be recommended for the use in field practice with minor modifications. Calves that stand insecurely and are not able to correct their position if pushed

The aim of this study was to evaluate the effects of different physical treatments of bovine colostrum and hospital milk on milk bacteriology, immunoglobulin G (IgG) and lactoferrin concentrations, calf serum IgG concentrations and calf health, growth and survivability. Pooled colostrum samples (n=297) were heat treated (HTC; 63°C for 60 min), exposed to ultraviolet light (UVC; 45 J/cm(2)) or untreated ('raw', RC). Hospital milk (n=712) was subjected to high temperature short time pasteurization (HTST; 72°C for 15s), ultraviolet light irradiation (UVH; 45 J/cm(2)) or was untreated. Neonatal Holstein heifer calves (n=875) were randomly enrolled (309 HTC, 285 UVC, 281 RC) and block randomized (by colostrum treatment) into hospital milk treatments HTST (n=449) or UVH (n=426). HTC was more effective than UVC and HTST was more effective than UVH in reducing bacterial counts. IgG and lactoferrin concentrations were significantly lower in HTC and UVC than in RC. Lactoferrin concentrations were significantly lower in HTST than in UVH or untreated hospital milk. There were no significant differences in serum IgG concentrations among calves fed HTC, UVC or RC. Colostrum and hospital milk treatments did not have any significant effect on calf body weight gain, survivability, or frequency of diarrhea or pneumonia. Copyright © 2013 Elsevier Ltd.

In long-distance migratory systems, local fluctuations in the predator-prey ratio can exhibit extreme variability within a single year depending upon the seasonal location of migratory species. Such systems offer an opportunity to empirically investigate cyclic population density effects on short-term food web interactions by taking advantage of the large seasonal shifts in migratory prey biomass.We utilized a large-mammal predator-prey savanna food web to evaluate support for hypotheses relating to the indirect effects of "apparent competition" and "apparent mutualism" from migratory ungulate herds on survival of resident megaherbivore calves, mediated by their shared predator. African lions ( Panthera leo ) are generalist predators whose primary, preferred prey are wildebeests ( Connochaetes taurinus ) and zebras ( Equus quagga ), while lion predation on secondary prey such as giraffes ( Giraffa camelopardalis ) may change according to the relative abundance of the primary prey species.We used demographic data from five subpopulations of giraffes in the Tarangire Ecosystem of Tanzania, East Africa, to test hypotheses relating to direct predation and indirect effects of large migratory herds on calf survival of a resident megaherbivore. We examined neonatal survival via apparent reproduction of 860 adult females, and calf survival of 449 giraffe calves, during three precipitation seasons over 3 years, seeking evidence of some effect on neonate and calf survival as a consequence of the movements of large herds of migratory ungulates.We found that local lion predation pressure (lion density divided by primary prey density) was significantly negatively correlated with giraffe neonatal and calf survival probabilities. This supports the apparent mutualism hypothesis that the presence of migratory ungulates reduces lion predation on giraffe calves.Natural predation had a significant effect on giraffe calf and neonate survival, and could significantly affect giraffe

The objectives of this study were to evaluate the presence of thermophilic Campylobacter in feces of calves with and without diarrhea on dairy farms and to survey farm characteristics and management practices to define risk factors for the presence of Campylobacter. Fifty dairy farms were chosen based on the presence of calf diarrhea, and 50 farms in which calves were free from diarrhea served as a standard of comparison. In total, fecal samples were taken from 382 calves. Farm data and management practices were surveyed using a questionnaire on farm. Campylobacter were isolated from fecal samples and colonies were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis. Campylobacter spp., mainly Campylobacter jejuni (93% of isolated species), were detected on 33% of the farms and in 14.9% of the calves. Detection of Campylobacter did not differ between farms or between calves with and without diarrhea, although we found a tendency for calves suffering from diarrhea to shed Campylobacter more often. Calves may act as a reservoir of Campylobacter and may therefore lead to infections of other animals and humans. To define control strategies to reduce Campylobacter in calves, we identified on-farm risk factors. The presence of poultry on the farm, the time of cow-calf separation following birth, the use of an individual bucket for each calf, the feeding of waste milk, and the duration of individual housing were variables significantly associated with the appearance or absence of Campylobacter.

A Case Study of Respiratory Disease in a Veal Calf Operation

Science.gov (United States)

Palechek, Neil P.; Schoonderwoerd, Matt; Perry, Allen W.

1987-01-01

An outbreak of respiratory disease occurred in a central Alberta veal operation, after production capacity had been increased fourfold. Mortality rate reached 24.6% despite agressive antibiotic therapy. A review of the records revealed a cyclical disease pattern in each room. Weekly cleaning of occupied calf rooms was correlated with the disease pattern. Aerosols generated by a high pressure sprayer appeared to trigger transmission of respiratory pathogens in malnourished neonatal calves. Disease occurrence decreased and profitability increased sixfold after the introduction of the following measures: 1) discontinuing the use of the high pressure washer in the occupied calf rooms, 2) feeding calves a better quality milk replacer with supplemental milk for the poorest calves, 3) sale-yard calf purchases were abandoned in favor of direct buying.

Full Text Available Aim: This study was undertaken to determine the household, calf management, and calf factors associated with the occurrence of Eimeria, Cryptosporidia, and diarrhea in pre-weaned calves reared in smallholder dairy farms in Mukurweini Sub-County of Nyeri County, Kenya. In addition, the study also evaluated factors associated with average daily weight gain in the same pre-weaned calves. Materials and Methods: A total of 112 newborn calves (63 males and 49 females on 111 farms (1 set of twins were followed for 2 months between June 2013 and August 2013. Two calves were lost to follow-up. A pre-tested questionnaire was used to collect data on household characteristics and calf management practices in the 111 selected farms. On the first visit to the farm (within 7 days of the birth of the calf, blood samples were collected from the jugular vein to assess the level of maternal immunity acquired by the calf, by determining the serum total protein and selenium concentration. At 4 and 6 weeks of age, fecal samples from the calves were collected to assess the presence of Cryptosporidia and Eimeria oocysts. Every 2 weeks for 2 months, the calves and their environments were examined, their 2-week consumption and health history were recorded, and weights were estimated with a weight tape. Each of the factors was evaluated in a univariable regression model and only those found to be significant (p≤0.20 were included in a multivariable model. Elimination of non-significant factors was done in the multivariable model through a backward elimination procedure so that only those variables which were confounders, and/or significant at (p≤0.05 remained in the final model. Results: About 37% (41/110 of the calves experienced diarrhea at least once during the 2-month study period. The overall period prevalence of Eimeria and Cryptosporidia was 42.7% (47/110 and 13.6% (15/110, respectively. Low serum protein was associated with 1.8 and 2.4 times the odds of

Up to one-third of dairy calves are born after dystocia and this is a major cause of calf mortality. This study investigated the neonatal physiology, survival, health and subsequent growth of dairy calves following dystocia and is the first longitudinal study to analyse multiple effects and to look beyond the perinatal period. A total of 455 live born Holstein calves (N: No assistance, n=360; FN: Farmer assistance but normally presented calf, n=82; FM: Farmer assistance of malpresented calf, n=13) were followed from birth to first service (heifers) or until leaving the farm (bulls). Compared to N calves, FN and FM animals had higher salivary cortisol concentrations at day 1 (PDystocia had no biologically significant impact on rectal temperature throughout the first 4 days (P>0.05). During the first 60 days, FM calves had a higher proportion of days with non-routine health treatments (Pdystocia category (P>0.05). Calves which survive dystocia experience lower passive immunity transfer, higher mortality and higher indicators of physiological stress. Such calves have poorer welfare in the neonatal period and possibly beyond. Strategies need to be implemented to improve the subsequent health and welfare of such calves and to lower the incidence of dystocia. Copyright © 2012 Elsevier Ltd. All rights reserved.

Group A Rotavirus (RVA) is the leading cause of severe diarrhea in children. The aims of the present study were to determine the neutralizing activity of VP6-specific llama-derived single domain nanoantibodies (VHH nanoAbs) against different RVA strains in vitro and to evaluate the ability of G6P[1] VP6-specific llama-derived single domain nanoantibodies (VHH) to protect against human rotavirus in gnotobiotic (Gn) piglets experimentally inoculated with virulent Wa G1P[8] rotavirus. Supplementation of the daily milk diet with 3B2 VHH clone produced using a baculovirus vector expression system (final ELISA antibody -Ab- titer of 4096; virus neutralization -VN- titer of 256) for 9 days conferred full protection against rotavirus associated diarrhea and significantly reduced virus shedding. The administration of comparable levels of porcine IgG Abs only protected 4 out of 6 of the animals from human RVA diarrhea but significantly reduced virus shedding. In contrast, G6P[1]-VP6 rotavirus-specific IgY Abs purified from eggs of hyperimmunized hens failed to protect piglets against human RVA-induced diarrhea or virus shedding when administering similar quantities of Abs. The oral administration of VHH nanoAb neither interfered with the host's isotype profiles of the Ab secreting cell responses to rotavirus, nor induced detectable host Ab responses to the treatment in serum or intestinal contents. This study shows that the oral administration of rotavirus VP6-VHH nanoAb is a broadly reactive and effective treatment against rotavirus-induced diarrhea in neonatal pigs. Our findings highlight the potential value of a broad neutralizing VP6-specific VHH nanoAb as a treatment that can complement or be used as an alternative to the current strain-specific RVA vaccines. Nanobodies could also be scaled-up to develop pediatric medication or functional food like infant milk formulas that might help treat RVA diarrhea.

Why Do So Many Calves Die on Modern Dairy Farms and What Can We Do about Calf Welfare in the Future?

Full Text Available Poor bovine neonatal survival rates are an international animal welfare issue. The key modifiable risk factors associated with such loss are age at first calving in primiparae, calf breed, gender and gestation length and calving management. The primary causes of mortality in the perinatal period are calving problems, in particular dystocia, defined as both difficult and abnormal calvings. Calf loss rates are rising on modern dairy farms in many countries internationally. High calf loss rates are often not recognised at national or at farm-level; recording needs to be improved. Improving bovine neonatal survival requires re-prioritization of this issue. Stakeholders need to be made cognisant of this prioritization. Actions to effect change need to occur at both national and farm-levels. National-level actions need firstly to address raising awareness of the issue. Farm-level actions need to focus on identifiable problem farms through targeted surveillance. Application of existing knowledge to alter modifiable risk factors is the key to improving calf welfare in the future. Research also has a role to play in filling knowledge gaps in particular about the ‘unexplained stillbirth’.

The objective of this study was to investigate calf management practices on beef cow-calf operations and determine associations with herd-level morbidity and mortality of pre-weaned calves. A 40-question survey about management practices, morbidity and mortality was administered to cow-calf producers by distributing paper surveys and by circulating an online link through various media. A total of 267 producers completed the survey. Data were analyzed with descriptive statistics and multivariable linear regression models. Average herd-level treatment risk for pre-weaning calf diarrhea (PCD) and bovine respiratory disease (BRD) were 4.9% and 3.0%, respectively. Average herd-level mortality within the first 24 h of life (stillbirth), from 1 to 7 days and 7 days to weaning were 2.3%, 1.1%, and 1.4%, respectively. Operations that never intervened at parturition had 4.7% higher PCD than those that occasionally did. On operations using small elastrator bands for castration, PCD was 1.9% higher than those using other methods. For every increase of 100 cows in herd size, BRD decreased by 1.1%. The association between BRD and PCD varied by when calving season began. Operations that used off-farm, frozen colostrum had a 1.1% increase in stillbirths. Operations that verified a calf had suckled had 0.7% lower mortality from 1 to 7 days of age. Those that intervened when colostrum was abnormal or that used small elastrator bands for castration had 1.9% and 1.4% higher mortality during the 1st week of life, respectively, compared with other operations. Mortality from 7 days to weaning was lower by 0.7% when calving season started in April compared with January or February and was higher by 1.0% for each additional week of calving season. Operations that intervened with colostrum consumption for assisted calvings had lower mortality from 7 days to weaning by 0.8% compared with those that did not. For every 1.0% increase in BRD, mortality from 7 days to weaning increased by 1

standardized procedures for conducting and reporting data from calf experiments was first published. A very active area of calf nutrition research from the late 1970s to the mid 1980s was colostrum quality, feeding, and preservation; more than 60 such research articles were published in the journal during this time. Various nonmilk protein sources were evaluated. Extensive studies were done evaluating trace and major mineral requirements in calves along with some vitamin studies. Throughout the 1970s, 1980s, and 1990s, the primary objective of most calf research was how to wean healthy, adequately grown calves at an early age-generally less than 30 d of age. This program was reviewed in a 1979 publication. Research on calf starter ingredients, nutrient composition, and additives was minimal in the 1980s and 1990s given the importance of starter intake to the success of early weaning, but the role of water intake in starter intake and growth was established. Research on issues with calves continued to increase during the last 20-yr period as evidenced by publication of more than 580 articles in JDS as well as many more in other refereed journals. In addition to papers contributed by several universities in the United States and Canada, the number of papers authored by scientists at universities and institutes in other countries increased dramatically during this period. Factors influencing colostral antibody absorption, heat treatment of colostrum, and efficacy of colostrum supplements and replacers were reported. Most studies in this period related to nutrition. Studies were published supporting greater neonatal growth rates from feeding more milk replacer but with a higher crude protein content than traditional. Protein energy effects on growth and body composition were evaluated in concert with greater growth rates. Milk and nonmilk protein sources in milk replacers along with AA supplementation were evaluated. Limited studies were done with fat sources and fatty acid

Acute diarrhea in children

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

Diarrhea is not a single disease, but only a symptom of different diseases. Diarrhea is characterized by an increase in bowel movements (more than three per day) and an increased liquidity of stools. Acute diarrheas are defined as those that last less than four weeks, whereas chronic diarrheas persist for more than four weeks. The pathophysiological basis of diarrhea is a disturbed enteral water- and electrolyte balance, which can be caused by an increased secretion of osmotically active electrolytes (secretory diarrhea) or the increased ingestion of osmotically active substances (osmotic diarrhea). The stool characteristics allows to distinguish watery, bloody and fatty diarrhea. Acute diarrheas are mostly caused by an infectious agent (viruses, bacteria and parasites), whereas the differential diagnosis of chronic diarrhea is considerably larger and therefore the diagnostic work-up is more complex.

Fever rather than diarrhea or vomiting was the most common symptom of neonatal rotavirus (RV) infection in our previous study. We investigated whether RV infection is a major cause of neonatal fever and compared the clinical characteristics of bacterial infection, viral infection and unknown causes of neonatal fever. We reviewed the electronic medical records of 48 newborns aged ≤28 days who were admitted to the Special Care Nursery of Hanyang University Guri Hospital for fever (≥38°C) from 2005 to 2009. All the newborns underwent complete blood count, urinalysis, C-reactive protein, cultures of blood, urine, and cerebrospinal fluid as well as stool RV enzyme-linked immunosorbent assay. Respiratory virus polymerase chain reaction for cough or rhinorrhea, and stool culture for diarrhea were also done. All the babies were term, with mean age 13 ± 8 days and peak body temperature 38.5 ± 0.5°C. The causes of neonatal fever were viral (44%), bacterial (10%) and unknown (46%). The viral infections included RV (n = 12), enterovirus (n = 6), respiratory syncytial virus (n = 2), and rhinovirus (n = 1). All the rotavirus genotypes were G4P[6]. Only three of 12 RV-infected febrile newborns had diarrhea. The bacterial infections included three cases of urinary tract infection (Escherichia coli, n = 2; Klebsiella pneumoniae, n = 1), and two cases of sepsis complicated with meningitis (all Streptococcus agalactiae). RV infection is the most common single cause of neonatal fever. It may be necessary to include stool RV tests for febrile newborns. © 2017 Japan Pediatric Society.

It is well known that vitamin E and selenium deficiencies in domestic ruminants can lead to white muscle disease. After a clinically normal gestation period at Ouwehand Zoo in the Netherlands, a newborn giraffe ( Giraffa camelopardalis) calf showed clinical signs of white muscle disease almost immediately after birth. The calf was rejected by the mother and was euthanized 3 days later because of deterioration of clinical signs. At necropsy, pulmonary edema and pallor of skeletal and heart muscles was noted. Histologically, there was hyaline degeneration of skeletal muscle myocytes and pulmonary edema. Blood concentrations of vitamin E were ≤ 0.7 mg/L. Based on clinical, biochemical, and gross and microscopic pathological findings, congenital nutritional myodegeneration was diagnosed. This case of neonatal white muscle disease is particularly remarkable given that the diet of the dam contained more than the recommended amount of vitamin E.

A total of 31,396 females born from 2010 to 2013 in 43 large-scale Holstein-Friesian herds were phenotyped for calf and cow disease traits using a veterinarian diagnosis key. Calf diseases were general disease status (cGDS), calf diarrhea (cDIA), and calf respiratory disease (cRD) recorded from birth to 2 mo of age. Incidences were 0.48 for cGDS, 0.28 for cRD, and 0.21 for cDIA. Cow disease trait recording focused on the early period directly after calving in first parity, including the interval from 10 d before calving to 200 d in lactation. For cows, at least one entry for the respective disease implied a score = 1 (sick); otherwise, score = 0 (healthy). Corresponding cow diseases were first-lactation general disease status (flGDS), first-lactation diarrhea (flDIA), and first-lactation respiratory disease (flRD). Additional cow disease categories included mastitis (flMAST), claw disorders (flCLAW), female fertility disorders (flFF), and metabolic disorders (flMET). A further cow trait category considered first-lactation test-day production traits from official test-days 1 and 2 after calving. The genotype data set included 41,256 single nucleotide polymorphisms (SNP) from 9,388 females with phenotypes. Linear and generalized linear mixed models with a logit link-function were applied to Gaussian and categorical cow traits, respectively, considering the calf disease as a fixed effect. Most of the calf diseases were not significantly associated with the occurrence of any cow disease. By trend, increasing risks for the occurrence of cow diseases were observed for healthy calves, indicating mechanisms of disease resistance with aging. Also by trend, occurrence of calf diseases was associated with decreasing milk, protein, and fat yields. Univariate linear and threshold animal models were used to estimate heritabilities and breeding values (EBV) for all calf and cow traits. Heritabilities for cGDS and cRD were 0.06 and 0.07 for cDIA.

Full Text Available Neonatal calf diarrhea remains one of the most important problems faced by livestock, causing great economic losses. This study investigated the prevalence of Salmonella and Escherichia coli, especially enterotoxigenic E. coli (ETEC, in diarrheic calves. Fecal samples were collected from 127 diarrheic calves up to 3 months of age at 12 farms from different governorates in Egypt. 119 bacterial isolates (93.7% were recovered and the prevalences of Salmonella and E. coli in diarrheic calves were 18.1% and 75.6%, respectively. Serotyping of Salmonella isolates revealed that S. Enteritidis and S. Typhimurium were the most prevalent serotypes, representing 60.9% and 30.4%, respectively, while S. Dublin was 8.7%. Serogrouping of E. coli isolates showed that 10 O-serogroups were obtained where O26 and O103 were the most prevalent (17.7% of each. Salmonella serotypes showed positive results with PCR test using oligonucleotide primer amplifying 521 bp fragment of invA gene of Salmonella while 70% of E. coli serogroups possessed ETEC virulent gene (K99. The in-vitro antibiotic sensitivity test indicated that Salmonella serotypes showed high sensitivity against enrofloxacin, spectinomycin and neomycin while E. coli isolates showed high sensitivities against marbofloxacin, spectinomycin and neomycin only.

The objective of the study was to evaluate if on-farm heat treatment of colostrum and bulk tank milk can improve calf health status and morbidity and mortality rates during the first 21d of life in neonatal Holstein calves receiving appropriate colostrum ingestion. A total of 587 calves were randomly assigned to 2 groups of males and females over 18mo. The nonpasteurized group (n=287, 143 males and 144 females) was fed frozen (-20°C) colostrum (6-8L during the first 12h of life) that was previously reheated up to 40°C. They were also fed refrigerated (4°C) raw milk from the bulk tank that was also reheated up to 40°C (1.8L every 12h). The pasteurized group (n=300, 150 males and 150 females) was also fed colostrum and milk, but both were pasteurized before freezing. Blood samples were drawn from all calves to obtain serum at 2 to 5d of life. Serum total protein (g/dL) was determined using a commercially available refractometer. Colostrum and milk underwent routine bacteriological analysis to determine total plate counts (cfu/mL) and total coliform counts (cfu/mL). All the calves underwent clinical examination every 24h during the first 21d of life. Every day, calves were clinically diagnosed either as being healthy or suffering from respiratory disease, neonatal calf diarrhea, or suffering other diseases. On-farm heat treatment for colostrum and milk reduced total plate counts and total coliform counts between 1 and 2 log10. Pasteurization of colostrum and milk significantly decreased the morbidity and mortality (5.2 and 2.8%) in comparison with calves receiving nonpasteurized colostrum and milk (15.0 and 6.5%), respectively, during the first 21d of life, even in animals receiving appropriate colostrum ingestion.

125I-labeled immunoglobulin (Ig)G1 in colostral whey was used to determine the region of maximum absorption of Ig from the small intestine of the neonatal calf and the variation in Ig absorption among calves at the intestinal level. In experiment 1, 5 segments (approx 5%, 35%, 60%, 80%, and 95% of the duodenocecal length) were formed in the small intestine of 9 colostrum-deprived calves shortly after birth. These segments were injected with colostral whey containing 125I-IgG1 4 hours after birth, and uptake, transfer, and absorption (defined as uptake plus transfer) were determined for each segment 2 hours later. Raw data were adjusted for the milligrams of IgG1 injected per gram of intestinal tissue to obtain the least squares mean (LSM) value. The LSM values for absorption of IgG1 from distal segments 3, 4, and 5 were significantly greater (P less than 0.05) than those values for proximal segments 1 and 2. The region of the maximum IgG1 absorption was the lower small intestine, 60% to 80% of the duodenocecal length. There was also an indication of independence between uptake and transfer in each of the segments. Significant differences (P less than 0.05) were present among calves in the LSM values for uptake and absorption, but not for transfer. In experiment 2, thoracic ducts of 8 newborn calves were cannulated 4 to 5 hours after birth. At 6 hours after birth, colostral whey with 125I-IgG1 was injected into an intestinal segment (approx 60% to 80% of the duodenocecal length)

Spontaneous calf haematoma is a rare condition and few case reports have been published in the English literature. Common conditions like deep vein thrombosis and traumatic gastrocnemius muscle tear need to be considered when a patient presents with unilateral calf swelling and tenderness. Ultrasound and Magnetic Resonance Imaging are essential for confirmation of diagnosis. The purpose of this paper is to report on a rare case of spontaneous calf hematoma and its diagnosis and management.

Group A rotaviruses (RVA) are the main cause of neonatal calve diarrhea (NCD) in Morocco. In this study, we isolated RVA strains from NCD clinical samples in order to support RVA disease control in Morocco. This isolation process constitutes a first step toward vaccine development. Thirteen fecal samples were obtained from calves with a single episode of neonate calf diarrhea at three different dairies and two samples were collected from field during a severe NCD outbreak. Diagnosis of RVA infection was based on fecal immune-chromatographic rapid test and further evaluated for their hemagglutination (HA) activity. RVA isolation was carried out on MA104 cells after inoculates were treated with different concentrations of trypsin TPCK. All RVA isolates were confirmed by LSI VetMAX™ Triplex Ruminant Rotavirus & Coronavirus Real-Time PCR kit. G and P typing were determined by direct sequencing of the VP4 and VP7 amplicons. RVA isolation was achieved for nine clinical samples following one or two passages (60 %) and was properly depended on HA activity and trypsin treatment of inoculates. The first sign of CPE detected consisted of increased cell granularity, obscure cell boundaries, cell rounding, and eventual degeneration and detachment of cells. At lower TPCK concentration (3-10 μg/inoculum), no changes at the cellular level were observed, while cells activated with 25-30 μg of trypsin/inoculums, they degenerated and trypsin cytotoxicity was enhanced. Appreciable changes in cell's morphology were detected with optimal trypsin concentration of 15-20 μg trypsin/inoculums. Data from qRT-PCR confirmed that unsuccessful cultivations have No-Ct, and all nine isolates have Ct values ranged between 12.17 and 24.69. Analysis sequencing revealed that field isolates were of G6 P[5] serotype and isolates from the dairy NCD samples were of G10 P[14] serotype. To our knowledge, this is the first study in Morocco which reports the circulation of G10P[14] in NCD on dairy

Bovine neonatal pancytopenia (BNP; previously known as idiopathic haemorrhagic diathesis and commonly known as bleeding calf syndrome) is a novel haemorrhagic disease of young calves which has emerged in a number of European countries during recent years. Data were retrospectively collected during June to November 2010 for 56 case calves diagnosed with BNP between 17 March and 7 June of the same year. These were compared with 58 control calves randomly recruited from herds with no history of BNP. Multivariable logistic regression analysis showed that increased odds of a calf being a BNP case were associated with its dam having received PregSure® BVD (Pfizer Animal Health) vaccination prior to the birth of the calf (odds ratio (OR) 40.78, p<0.001) and its herd of origin being located in Scotland (OR 9.71, p = 0.006). Decreased odds of a calf being a BNP case were associated with the calf having been kept outside (OR 0.11, p = 0.006). The longer that a cattle herd had been established on the farm was also associated with decreased odds of a calf in that herd being a BNP case (OR 0.97, p = 0.011). PMID:22606224

Secretory diarrhea.

Science.gov (United States)

Schiller, L R

1999-10-01

Diarrhea, defined as loose stools, occurs when the intestine does not complete absorption of electrolytes and water from luminal contents. This can happen when a nonabsorbable, osmotically active substance is ingested ("osmotic diarrhea") or when electrolyte absorption is impaired ("secretory diarrhea"). Most cases of acute and chronic diarrhea are due to the latter mechanism. Secretory diarrhea can result from bacterial toxins, reduced absorptive surface area caused by disease or resection, luminal secretagogues (such as bile acids or laxatives), circulating secretagogues (such as various hormones, drugs, and poisons), and medical problems that compromise regulation of intestinal function. Evaluation of patients with secretory diarrhea must be tailored to find the likely causes of this problem. Specific and nonspecific treatment can be valuable.

Calf pain is a common complaint among runners of all ages but is most frequent in masters athletes. This article focuses on injuries to the triceps surae or true 'calf muscles.' The most common calf injury is a tear of the medial gastrocnemius muscle (Tennis Leg) but other structures including the lateral gastrocnemius, plantaris and soleus also may be the cause of muscular pain. This article looks at the presentation, evaluation, and treatment of these injuries. We also highlight some examples of musculoskeletal ultrasound which is a valuable tool for rapid diagnosis of the cause and extent of injury.

CALF CIRCUMFERENCE AT BIRTH: A SCREENING METHOD FOR DETECTION OF LOW BIRTH WEIGHT

Directory of Open Access Journals (Sweden)

Sandip Kumar

2012-12-01

Full Text Available Background: Low Birth Weight (LBW babies run a higher risk of morbidity and mortality in the perinatal period. However, in our country where almost 70-80% births take place at home and peripheral hospitals, taking accurate weight is a problem due to unavailability of weighing scale and trained personnel. Hence there is a constant search for newer methods to detect LBW babies so that early interventions can be instituted. Various authors have used different surrogate anthropometric measurements from different parts of our country. In the present study, an attempt was made to validate the feasibility of using calf circumference as a predictor of LBW babies that can be used by a trained or untrained person. Objectives: To study various anthropometric measurements including calf circumference in newborns and to correlate various measurements with birth weight. Methods: The present study was conducted in the department of Social & Preventive Medicine, MLB Medical College, Jhansi (UP for a period of one year. The study included 1100 consecutively delivered neonates in the maternity ward of MLB Medical College Hospital, Jhansi (UP. The birth weight (Wt, crown heel length (CHL, crown rump length (CRL, head circumference (HC, chest circumference (CC, mid arm circumference (MAC, thigh circumference (TC and calf circumference (CC by standard techniques. All the measurements were taken by a single person throughout the study period with in 24 hours of delivery. Standard statistical methods were adopted for determination of critical limit, sensitivity, specificity and correlation coefficient of different anthropometric measurements in relation to birth weight. Results: Analysis of data indicates that out of 1100 newborns, 55.64% were low birth weight. The percentage of newborns > 2500gm was 44.36. Overall average birth weight was 2348 ± 505gm. Out of 1100 newborns, 608 (55.27% were males and 492 (44.73% were females. Average birth weight for males was 2412

Efficacy of calf:cow ratios for estimating calf production of arctic caribou

Cameron, R.D.; Griffith, B.; Parrett, L.S.; White, R.G.

2013-01-01

Caribou (Rangifer tarandus granti) calf:cow ratios (CCR) computed from composition counts obtained on arctic calving grounds are biased estimators of net calf production (NCP, the product of parturition rate and early calf survival) for sexually-mature females. Sexually-immature 2-year-old females, which are indistinguishable from sexually-mature females without calves, are included in the denominator, thereby biasing the calculated ratio low. This underestimate increases with the proportion of 2-year-old females in the population. We estimated the magnitude of this error with deterministic simulations under three scenarios of calf and yearling annual survival (respectively: low, 60 and 70%; medium, 70 and 80%; high, 80 and 90%) for five levels of unbiased NCP: 20, 40, 60, 80, and 100%. We assumed a survival rate of 90% for both 2-year-old and mature females. For each NCP, we computed numbers of 2-year-old females surviving annually and increased the denominator of CCR accordingly. We then calculated a series of hypothetical “observed” CCRs, which stabilized during the last 6 years of the simulations, and documented the degree to which each 6-year mean CCR differed from the corresponding NCP. For the three calf and yearling survival scenarios, proportional underestimates of NCP by CCR ranged 0.046–0.156, 0.058–0.187, and 0.071–0.216, respectively. Unfortunately, because parturition and survival rates are typically variable (i.e., age distribution is unstable), the magnitude of the error is not predictable without substantial supporting information. We recommend maintaining a sufficient sample of known-age radiocollared females in each herd and implementing a regular relocation schedule during the calving period to obtain unbiased estimates of both parturition rate and NCP.

Calf health from birth to weaning. II. Management of diarrhoea in pre-weaned calves

Directory of Open Access Journals (Sweden)

Lorenz Ingrid

2011-09-01

Full Text Available Abstract Calfhood diseases have a major impact on the economic viability of cattle operations. The second of this three part review series considers the management of diarrhoeic diseases in pre-weaned calves. In neonatal calf diarrhoea, oral rehydration therapy is the single most important therapeutic measure to be carried out by the farmer and is usually successful if instigated immediately after diarrhoea has developed. Continued feeding of milk or milk replacer to diarrhoeic calves is important, to prevent malnourishment and weight loss in affected calves. Indiscriminative antibiotic treatment of uncomplicated diarrhoea is discouraged, whereas systemically ill calves can benefit from systemic antibiotic treatment for the prevention of septicaemia or concurrent diseases. Ancillary treatments and specific preventive measures are discussed. Eimeriosis has a high economic impact on the farming industries due to direct cost of treatment and calf losses, but especially due to decreased performance of clinically as well as sub-clinically affected animals. Emphasis lies on prophylactic or metaphylactic treatment, since the degree of damage to the intestinal mucosa once diarrhoea has developed, makes therapeutic intervention unrewarding.

2000-07-01

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

Beef cow-calf production.

Science.gov (United States)

Feuz, Dillon M; Umberger, Wendy J

2003-07-01

Cow-calf production occurs in all 50 states over varied resource bases and under vastly different environmental conditions. Multiple breeds exist and management styles and objectives are as numerous as the number of cow-calf producers. There is not one area of the country, one breed of cattle, or one management style that is most profitable for producing cows and calves. There are, however, some common strategies that can be employed by cow-calf producers to enhance profitability. Costs need to be controlled without jeopardizing cow herd productivity or net returns. It appears that the cost associated with purchased and harvested feeds varies considerably across operations. Understanding cyclic and seasonal price patterns, weight-price slides, cattle shrink, and other marketing costs can help producers enhance their profit by marketing (and not by just selling) their cattle. Producers with superior cattle genetics can become part of a specific alliance or, at a minimum, document the performance of their cattle so that they can get paid for the superior genetics. The beef industry is changing and will likely continue to change. Cow-calf producers will need to examine their own management practices to determine whether they are optimal for the current industry. Those producers who are most adept at matching their management abilities to their cattle type, their resource base, and the appropriate market outlet will be the most successful in the future.

Performance and Health of Group-Housed Calves Kept in Igloo Calf Hutches and Calf Barn

2013-04-01

Full Text Available Group-reared calves are usually housed in common buildings, such as calf barns of all sorts; however, there are concerns about this practice due to problems such as an increased incidence of diseases and poor performance of the calves. Group calf rearing using igloo hutches may be a solution combining the benefits of individual and group housing systems. The aim of this study was to evaluate group-reared calves housed in Igloo-type hutches compared with those housed in common calf barns. The experiment was carried out on a large private dairy farm located in Vorpommern, Germany. A total of 90 Deutsche-Holstein bull calves were assigned to 2 treatment groups: the calf-barn group, with calves grouped in pens in a building, and the Igloo-hutch group, with calves housed in outdoor enclosures with an access to group igloo-style hutches. Calves entering the 84-day experiment were at an average age of about three weeks, with the mean initial body weight of about 50 kg. The calves housed in the group Igloo hutches attained higher daily weight gains compared to those housed in the calf barn (973 vs 721 g/day, consumed more solid feeds (concentrate, corn grain and maize silage: (1.79 vs 1.59 kg/day, and less milk replacer (5.51 vs 6.19 kg/day, had also a lower incidence of respiratory diseases (1.24 vs 3.57% with a shorter persistence of the illness.

Little is known on the effects of common calf diseases on mortality and carcass traits in the white veal industry (special-fed veal), a highly integrated production system, currently criticized for the intensive pro- and metaphylactic use of antimicrobials. The objective of the present study was to determine the impact of bovine respiratory disease (BRD), diarrhea, arthritis and otitis on the economically important parameters of mortality, hot carcass weight (HCW), carcass quality, fat cover and meat color. For this purpose, a prospective study on 3519 white veal calves, housed in 10 commercial herds, was conducted. Case definitions were based on clinical observation by the producers and written treatment records were used. Calves received oral antimicrobial group treatments in the milk during 25.2% of the production time on average. With an increasing percentage of the production cycle spent on oral antimicrobials, HCW reduced, whereas the odds for insufficient fat cover or an undesirable red meat color both decreased. Of the calves, 14.8%, 5.3%, 1.5% and 1.6% were individually diagnosed and treated for BRD, diarrhea, arthritis and otitis, respectively. Overall, 5.7% of the calves died and the mortality risk was higher in the first weeks after arrival. Calves that experienced one BRD episode showed a 8.2 kg reduction in HCW, a lower fat cover and an increased mortality risk (hazard ratio (HR) = 5.5), compared to calves which were not individually diagnosed and treated for BRD. With an increasing number of BRD episodes, these losses increased dramatically. Additionally, calves, which experienced multiple BRD episodes, were more likely to have poor carcass quality and an undesirable red meat color at slaughter. Arthritis increased the mortality risk (HR = 3.9), and reduced HCW only when associated with BRD. Otitis did only increase the mortality risk (HR = 7.0). Diarrhea severely increased the mortality risk (HR = 11.0), reduced HCW by 9.2 kg on

Preventative programs for respiratory disease in cow/calf operations.

Science.gov (United States)

Engelken, T J

1997-11-01

Control of respiratory disease in cow/calf operations presents many challenges. The incidence of disease in the suckling calf is not well documented and the logistics of handling range animals make control programs difficult to implement. Health programs have to be built around normal working patterns, and these patterns may not provide the best "fit" for immune management of the calf. Weaned calves undergo significant disease challenge when they enter typical marketing channels. This provides the potential for high levels of calf morbidity, mortality, medicine costs, and losses from decreased performance as they arrive at a stocker operation or feedyard. If preweaning calf health and preconditioning programs are used, they must be planned so that the producer has an opportunity to obtain a return on their investment. Options for increasing calf weight marketed, certified calf health sales, or retained ownership through the next phase of production should be evaluated carefully. Any potential increase in calf value must be weighed against program costs. This affords the veterinarian an opportunity to build on traditional disease management and prevention skills and expand their influence in overall ranch management.

2013-05-02

Escherichia coli strains were isolated from the feces of 130 diarrheic calves at different farms locations in Korea. The presence of the virulence genes, such as fanC, f41, f17a, eaeA, clpG, afa-8D, sta, stx1 and stx2, in each E. coli isolate was examined. Among the 314 isolates, 157 carried one or more of the virulence genes tested in this study. The most prevalent virulence gene was clpG (45.9%), although f17A (36.9%) and afa-8D (21.7%) were also frequently observed. The sta, stx1 and eaeA genes were detected in between approximately 13 and 17% of the isolates, and the fanC and fim41a genes were detected to a lesser extent. Collectively, our data indicated that diarrhea in calves in these locations can be ascribed to various virulence factors, and the pathogenesis may be more related to virulence genes such as, clpG, f17A, and afa-8D.

Calf mortality and morbidity commonly occurs within the first month of life postpartum. Standard health ranges are invaluable aids in diagnostic veterinary medicine to confirm normal or the degree and nature of abnormal parameters in (sub)clinically ill animals. Extensive research has indicated significant differences between the physiologies of neonate and adult cattle, particularly for blood parameters such as pH, base excess, anion gap, and bicarbonate (HCO 3 - ). The objective of this research was to determine the influence of age, sex, and breed type, in addition to environmental factors, on the normal blood gas profiles of neonatal calves, and thus develop a scientifically validated reference range accounting for any significant factors. The study was conducted on healthy neonatal calves (n = 288), and completed over a 2-yr period. Individual calf blood gas analysis was conducted for parameters of pH, base excess, Na + , K + , Ca 2+ , Cl - , glucose, total hemoglobin, HCO 3 - , pCO 2 , anion gap, strong ion difference, and hematocrit levels. Regression procedures examined the combined effect of year, farm, age, breed type, sex, and hours postfeeding on each variable. Significant effects were observed for age, sex, and breed type on several of the blood gas variables. Furthermore, year, farm, and hours postfeeding appeared to have less of an influence on neonatal bovine blood gas profiles. Consequently, specific ranges based on the neonate's age, sex, and breed type will allow for more detailed and accurate diagnosis of health and ill health in neonatal calves. The Authors.

Evaluation of chronic diarrhea.

Science.gov (United States)

Juckett, Gregory; Trivedi, Rupal

2011-11-15

Chronic diarrhea, defined as a decrease in stool consistency for more than four weeks, is a common but challenging clinical scenario. It can be divided into three basic categories: watery, fatty (malabsorption), and inflammatory. Watery diarrhea may be subdivided into osmotic, secretory, and functional types. Watery diarrhea includes irritable bowel syndrome, which is the most common cause of functional diarrhea. Another example of watery diarrhea is microscopic colitis, which is a secretory diarrhea affecting older persons. Laxative-induced diarrhea is often osmotic. Malabsorptive diarrhea is characterized by excess gas, steatorrhea, or weight loss; giardiasis is a classic infectious example. Celiac disease (gluten-sensitive enteropathy) is also malabsorptive, and typically results in weight loss and iron deficiency anemia. Inflammatory diarrhea, such as ulcerative colitis or Crohn disease, is characterized by blood and pus in the stool and an elevated fecal calprotectin level. Invasive bacteria and parasites also produce inflammation. Infections caused by Clostridium difficile subsequent to antibiotic use have become increasingly common and virulent. Not all chronic diarrhea is strictly watery, malabsorptive, or inflammatory, because some categories overlap. Still, the most practical diagnostic approach is to attempt to categorize the diarrhea by type before testing and treating. This narrows the list of diagnostic possibilities and reduces unnecessary testing. Empiric therapy is justified when a specific diagnosis is strongly suspected and follow-up is available.

Diarrhea is defined as reduced stool consistency, increased water content and number of evacuations per day. A wide array of causes and pathophysiological mechanisms underlie acute and chronic forms of diarrhea. This review focuses on the major clinical aspects which should aid clinicians to diagnose chronic diarrhea. Clinical history, physical examination and stool evaluation and the predominant stool characteristic, i.e., bloody, watery, and fatty diarrhea, may narrow the differential diagnosis. Although mainly involved in acute diarrhea, many different infectious agents, including bacteria, viruses and protozoa, can be identified in chronic bloody/inflammatory diarrhea by appropriate microbiological tests and colonoscopic biopsy analysis. Osmotic diarrhea can be the result of malabsorption or maldigestion, with a subsequent passage of fat in the stool leading to steatorrhea. Secretory diarrhea is due to an increase of fluid secretion in the small bowel lumen, a mechanism often identified in gastroenteropancreatic neuroendocrine tumors. The evaluation of the fecal osmotic gap may help to characterize whether a chronic diarrhea is osmotic or secretory. Fatty diarrhea (steatorrhea) occurs if fecal fat output exceeds the absorptive/digestive capacity of the intestine. Steatorrhea results from malabsorption or maldigestion states and tests should differentiate between these two conditions. Individualized diagnostic work ups tailored on pathophysiological and clinical features are expected to reduce costs for patients with chronic diarrhea.

Diarrhea is a frequent adverse event involving the most frequently antibiotics, laxatives and NSAI. Drug induced diarrhea may be acute or chronic. It may be due to expected, dose dependant properties of the drug, to immuno-allergic or bio-genomic mechanisms. Several pathophysiological mechanisms have been described resulting in osmotic, secretory or inflammatory diarrhea, shortened transit time, or malabsorption. Histopathological lesions sometimes associated with drug induced diarrhea are usually non specific and include ulcerations, inflammatory or ischemic lesions, fibrous diaphragms, microscopic colitis and apoptosis. The diagnosis of drug induced diarrhea, sometimes difficult to assess, relies on the absence of other obvious causes and on the rapid disappearance of the symptoms after withdrawal of the suspected drug.

A 30-year-old man had a recurrent painful calf swelling associated with gout that mimicked thrombophlebitis and possibly muscle tear. This painful calf swelling occurred in the absence of a subjective history of arthritis of the knee. A constellation of clinical signs was highly suggestive that gout was the cause of the painful calf swellings. Patients with similar conditions, after careful exclusion of thrombophlebitis, might be spared unnecessary and potentially dangerous anticoagulation or surgical intervention by early diagnosis of gout.

One hundred and seventy one neonates were treated with flomoxef (FMOX) and the clinical efficacy and safety were evaluated. The ages of the patients ranged from 0 to 28 days, and their body weights from 450 to 4300 g. Dose levels were 12.4 to 24.9 mg/kg every 8 or 12 hours for 1 to 10 days. Fifty two patients who responded to the FMOX treatment included 5 neonates with sepsis, 17 with suspected sepsis, 9 with urinary tract infections, 12 with pneumonia, 8 with intrauterine infections, and 1 with omphalitis. The other neonates could not be retrospectively diagnosed as bacterial infections. Of 52 patients, clinical results were excellent in 15, good in 34, fair in 1, and poor in 2. And the FMOX treatment was effective in 13 out of 14 patients in which causative bacteria were identified. The drug was well tolerated, but 6 neonates out of 33 over 5 days old had diarrhea. From these results, empiric treatment with FMOX against neonatal bacterial infection was as clinically useful as that of combination with ampicillin and gentamicin or cefotaxime and ampicillin in our neonatal intensive care unit. But, as this study did not include neonate with meningitis, efficacy to meningitis was not evaluated.

Acoustic development of a neonatal beluga whale (Delphinapterus leucas) at the John G. Shedd Aquarium

Carneiro, Brooke Elizabeth

Beluga whales (Delphinapterus leucas) were one of the first marine mammals to be in captivity and currently, nine zoological institutions in North America house belugas (Robeck et al., 2005). Despite their accessibility within these facilities, very little research has been done on the beluga whale that is related to their acoustic development or communication sounds. A male beluga calf named "Nunavik" was born at the John G. Shedd Aquarium on 14 December 2009, which provided an opportunity to examine the ontogeny of underwater sounds by a neonatal beluga from the birth throughout the first year of life. The objectives of the study were to: 1) collect underwater sound recordings of the beluga pod prior to the birth of the calf, 2) collect underwater sound recordings of the neonate during the first year of life, 3) document when and what types of sounds were produced by the calf, 4) compare sounds produced by the calf during agonistic and non-agonistic interactions, and 5) compare the acoustic features of sounds produced by the calf to sounds from the mother, a male beluga calf born at the Vancouver Aquarium in 2002, and other belugas at the John G. Shedd Aquarium. The first recordings of the beluga calf took place six hours following the birth for a two hour period. Subsequent recordings were made daily for one hour for the first two weeks of the calf's life and then twice per week until the calf was about six months of age. Later recordings were done less frequently; about once every other week, with no recordings during a 2-month period due to equipment failure. In total, sixty hours of underwater recordings of the belugas were collected from 26 September 2009 to 27 December 2010. Sounds were audibly and visually examined using Raven Pro version 1.4, a real-time sound analysis software application (Cornell Laboratory of Ornithology), and categorized into three categories (tones, noise, and noise with tones) based on the characteristics of underwater sounds from

Diarrhea is the second leading cause of death in children confinement housing, and Interval Collection (IC), which permits use of box stalls. CFC mimics human challenge model methodology but it is unknown if confinement housing impacts study end-points and if data gathered via this method is suitable for generalization to human populations. Using a modified crossover study design we compared CFC and IC and evaluated the impact of housing on study end-points. At birth, calves were randomly assigned to confinement (n = 14) or box stall housing (n = 9), or were challenged with 5 x 107 C. parvum oocysts, and followed for 10 days. Study end-points included fecal oocyst shedding, severity of diarrhea, degree of dehydration, and plasma cortisol. Calves in confinement had no significant differences in mean log oocysts enumerated per gram of fecal dry matter between CFC and IC samples (P = 0.6), nor were there diurnal variations in oocyst shedding (P = 0.1). Confinement housed calves shed significantly more oocysts (P = 0.05), had higher plasma cortisol (P = 0.001), and required more supportive care (P = 0.0009) than calves in box stalls. Housing method confounds study end-points in the calf model of cryptosporidiosis. Due to increased stress data collected from calves in confinement housing may not accurately estimate the efficacy of chemotherapeutics targeting C. parvum.

Thirty-one Holstein bull calves were purchased at birth from 3 dairy farms in Eastern Ontario. Each calf was assigned at random to oral treatment with either 5 mg of halofuginone lactate in 10.0 mL of aqueous carrier solution (Halocur, base comprised 10 mg of benzoic acid, 100 mg of lactic acid, and 0.3 mg of tartrazine) or 10 mL of placebo (Halocur base minus the active ingredient, halofuginone lactate) administered 15 to 30 min after morning milk feeding for the first 7 d of life. Intakes of milk, calf starter, and water, and fecal consistency score were recorded daily for 56 d. Calf weights were recorded weekly for 56 d. Fecal samples were taken from all calves at approximately 2, 7, 14, 21, and 28 d of age for isolation of Cryptosporidium parvum oocysts. Logistic and linear regression analyses were used to assess the effect of treatment on the incidence of diarrhea and C. parvum infection status. The odds of C. parvum shedding among calves in the halofuginone lactate-treated group was 70% lower than the odds of shedding among calves in the placebo group. In calves treated with halofuginone lactate, no oocyst shedding occurred until 2 wk of age, whereas 12.5% of calves in the placebo group began shedding oocysts during wk 1. From all ages of placebo-treated calves, 31 of 73 samples (42.5%) were positive for C. parvum, whereas only 15 of 67 samples (22.4%) from all ages of halofuginone lactate-treated calves tested positive. The largest number of C. parvum-positive samples occurred in the third week of life. There was a significant delay of 3.1 d in the incidence of diarrhea among calves treated with halofuginone lactate. Intake of milk and starter, body weight gains, and age at weaning were not significantly different between treatment groups.

Child and neonatal mortality is a serious problem in Bangladesh. The main objective of this study was to determine the most significant socio-economic factors (covariates) between the years 2011 and 2014 that influences on neonatal and child mortality and to further suggest the plausible policy proposals. We modeled the neonatal and child mortality as categorical dependent variable (alive vs death of the child) while 16 covariates are used as independent variables using χ 2 statistic and multiple logistic regression (MLR) based on maximum likelihood estimate. Using the MLR, for neonatal mortality, diarrhea showed the highest positive coefficient (β = 1.130; P  economic conditions for neonatal mortality. For child mortality, birth order between 2-6 years and 7 and above years showed the highest positive coefficients (β = 1.042; P  economic conditions for child mortality. This study allows policy makers to make appropriate decisions to reduce neonatal and child mortality in Bangladesh. In 2014, mother's age and father's education were also still significant covariates for child mortality. This study allows policy makers to make appropriate decisions to reduce neonatal and child mortality in Bangladesh.

The realized effect of multiple carnivores on juvenile ungulate recruitment may depend on the carnivore assemblage as well as compensation from forage and winter weather severity, which may mediate juvenile vulnerability to predation in ungulates. We used a time-to-event approach to test for the effects of risk factors on annual elk (Cervus canadensis) calf survival and to estimate cause-specific mortality rates for 2 elk populations in adjacent study areas in the southern Bitterroot Valley, Montana, USA, during 2011–2014. We captured and radio-tagged 286 elk calves: 226 neonates, and 60 6-month-old calves. Summer survival probability was less variable than winter (P = 0.12) and averaged 0.55 (95% CI = 0.47–0.63), whereas winter survival varied more than summer and significantly across study years (P = 0.003) and averaged 0.73 (95% CI = 0.64–0.81). During summer, elk calf survival increased with biomass of preferred forage biomass, and was slightly lower following winters with high precipitation; exposure to mountain lion (Puma concolor) predation risk was unimportant. In contrast, during winter, we found that exposure to mountain lion predation risk influenced survival, with a weak negative effect of winter precipitation. We found no evidence that forage availability or winter weather severity mediated vulnerability to mountain lion predation risk in summer or winter (e.g., an interaction), indicating that the effect of mountain lion predation was constant regardless of spatial variation in forage or weather. Mountain lions dominated known causes of elk calf mortality in summer and winter, with estimated cause-specific mortality rates of 0.14 (95% CI = 0.09–0.20) and 0.12 (95% CI = 0.07–0.18), respectively. The effect of carnivores on juvenile ungulate recruitment varies across ecological systems depending on relative carnivore densities. Mountain lions may be the most important carnivore for ungulates, especially where grizzly

Influence of environmental health in the cow-calf dyad system

Full Text Available Health factors influence the cow-calf dyad system in the postpartum period until the first suckling. The use of maternity paddock is a recommended management to facilitate the monitoring of parturient cows and calves. However, side effects occur due to environmental health conditions of maternity paddock that can affect the behaviour of the cow and result in the separation of calf from the mother, undermining sucking and the formation of the cow-calf dyad. To improve the understanding of this complex and dynamic system we built a conceptual model using the technique of causal loop diagram, Figure 1. By hypothesis, the environmental variables that act in maternity paddock influence the variable "Sources of pathogens in maternity". Those sources present a positive effect (in the same direction in the infection process of the calf and cow. Thus, a recommended practice is exposing the parturient cow to pathogens in maternity for sufficient period to stimulate their immune system and build disease resistance. That process contributes to improve the quality of colostrum that will be consumed by the calf during the first hours postpartum which has the function of increasing calf immunity, minimizing the occurrence of infections. In the model, sanitary environmental factors work in two Balance feedback loops (B1 and B2. The B1 cycle refers to the production of a healthy cow with a low level of infection by means of the variables: “Vaccine”, "Stimulation of cow immune system" and "Health resistance" with delay. The variable "Cow infection" has a negative influence (in the opposite direction in the "Maternal behaviour", thus the more infected the cow, the less investment will occur in maternal behaviour. The B2 cycle refers to the calf’s health condition, which is positively influenced by “Calf infection” which, in turn, has positive influence, contributing to the increase of "Calf diseases". The increase in “Calf diseases” generates an

[Chronic diarrhea: etiologies and diagnostic evaluation].

Science.gov (United States)

Schoepfer, A

2008-04-30

Chronic diarrhea is defined as a decrease in fecal consistency lasting for four or more weeks. A myriad of disorders are associated with chronic diarrhea. In developed countries, chronic diarrhea is mostly caused by non-infectious diseases. There are four pathogenic mechanisms leading to chronic diarrhea: osmotic diarrhea, secretory diarrhea, inflammatory diarrhea, and dysmotility. Overlaps between these mechanisms are possible. A 72-hour fecal collection as well as the fasting test are important diagnostic tools to identify the underlying pathomechanism. The identification of the pathomechanism narrows down the possible etiologies of chronic diarrhea and allows therefore a cost-saving diagnostic workup. The endoscopy is well established in the workup of chronic diarrhea. This article gives an overview about the main causes and mechanisms leading to chronic diarrhea and proposes an algorithm for the diagnostic evalution.

Testing for Chronic Diarrhea.

Science.gov (United States)

Raman, M

Chronic diarrhea is a frequently encountered symptom in clinical practice. The etiologies for chronic diarrhea are diverse and broad with varying clinical implications. A useful method of categorizing chronic diarrhea to guide a diagnostic work-up is a pathophysiology-based framework. Chronic diarrhea may be categorized as malabsorptive, secretory, osmotic, and inflammatory or motility related. Frequently, overlap between categories may exist for any given diarrhea etiology and diagnostic testing must occur with an understanding of the differential diagnosis. Investigations to achieve a diagnosis for chronic diarrhea range from screening blood and stool tests to more directed testing such as diagnostic imaging, and endoscopic and histological evaluation. The pathophysiology-based framework proposed in this chapter will allow the clinician to select screening tests followed by targeted tests to minimize cost and complications to the patient, while providing a highly effective method to achieve an accurate diagnosis. © 2017 Elsevier Inc.

In order to determine the factors related to mortality in Necrotizing enterocolitis (NEC), medical records of neonates and older infants diagnosed of NEC in the Instituto de Salud del Niño between 1984 and 1993 were retrospectively reviewed. Only the cases with a reliable roentgenologic, surgical or pathologic diagnosis were included. Sixty cases (46 infants and 14 neonates) were found, with a higher incidence in males (37 males vs 23 females). Twenty six cases required surgical treatment. Overall mortality was 77%, with no significant differences between neonates and infants, nor between those who were operated or not. Moderate or severe malnutrition, diarrhea as an early clinical manifestations, bronchopneumonia, shock and poor nutricional management were found as factors related to mortality.

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

Science.gov (United States)

Hibberd, Patricia L.

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

Chronic diarrhea is a common syndrome. An etiological diagnosis is often reached through clinical history, physical examination and simple tests. In some cases, when the etiology is not found, the syndrome is called functional diarrhea, even though established criteria are often not fulfilled. We present the case of a patient with diarrhea for several months. The most common causes were ruled out through clinical history, physical examination, radiographic studies and laboratory tests, and the patient was diagnosed with functional diarrhea. Three months later, the patient presented a neck mass, and biopsy revealed medullary carcinoma of the thyroid. A review of recommendations for the systematic evaluation of chronic diarrhea is presented. A general approach should include careful history taking characteristics of diarrhea (onset, associated symptoms, epidemiological factors, iatrogenic causes such as laxative ingestion), a thorough physical examination with special attention to the anorectal region, and routine laboratory tests (complete blood count and serum chemistry). In addition, stool analysis including electrolytes (fecal osmotic gap), leukocytes, fecal occult blood, excess stool fat and laxative screening can yield important objective information to classify the diarrhea as: osmotic (osmotic gaps > 125 mOsm/Kg), secretory (osmotic gaps diarrhea described above. A systematic approach to the evaluation of chronic diarrhea is warranted. Medullary thyroid carcinoma and other endocrine syndromes causing chronic diarrhea are very rare. Measurement of serum peptide concentrations should only be performed when clinical presentation and findings in stool or radiographic studies suggest this etiology.

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

Science.gov (United States)

Jung, Kwonil; Saif, Linda J

2015-05-01

Porcine epidemic diarrhea virus (PEDV), a member of the genera Alphacoronavirus in the family Coronaviridae, causes acute diarrhea/vomiting, dehydration and high mortality in seronegative neonatal piglets. For the last three decades, PEDV infection has resulted in significant economic losses in the European and Asian pig industries, but in 2013-2014 the disease was also reported in the US, Canada and Mexico. The PED epidemic in the US, from April 2013 to the present, has led to the loss of more than 10% of the US pig population. The disappearance and re-emergence of epidemic PED indicates that the virus is able to escape from current vaccination protocols, biosecurity and control systems. Endemic PED is a significant problem, which is exacerbated by the emergence (or potential importation) of multiple PEDV variants. Epidemic PEDV strains spread rapidly and cause a high number of pig deaths. These strains are highly enteropathogenic and acutely infect villous epithelial cells of the entire small and large intestines although the jejunum and ileum are the primary sites. PEDV infections cause acute, severe atrophic enteritis accompanied by viremia that leads to profound diarrhea and vomiting, followed by extensive dehydration, which is the major cause of death in nursing piglets. A comprehensive understanding of the pathogenic characteristics of epidemic or endemic PEDV strains is needed to prevent and control the disease in affected regions and to develop an effective vaccine. This review focuses on the etiology, epidemiology, disease mechanisms and pathogenesis as well as immunoprophylaxis against PEDV infection. Copyright © 2015 Elsevier Ltd. All rights reserved.

Circulating agents cause intestinal secretion or changes in motility with decreased intestinal transit time, resulting in secretory-type diarrhea. Secretory diarrhea as opposed to osmotic diarrhea is characterized by large-volume, watery stools, often more than 1 L per day; by persistence of diarrhea when patients fast; and by the fact that on analysis of stool-water, measured osmolarity is identical to that calculated from the electrolytes present. Although sodium plays the main role in water and electrolyte absorption, chloride is the major ion involved in secretion. Copyright © 2012 Elsevier Inc. All rights reserved.

Diarrhea is a very common event after transplantation, but its cause may be difficult to identify. The first step in determining the cause in any particular case is an understanding of the etiology of diarrhea in general. Although diarrhea often is categorized into such types as secretory versus osmotic, or electrolyte transport-related versus motility-related, a thorough understanding of the problem requires knowledge of how the paracrine, immune, nervous and endocrine systems react to each other as well as to infection, drugs or other stimuli.

The CALFED Bay-Delta Program faces a challenging assignment: to develop a collaborative state-federal management plan for the complex river system and involve multiple stakeholders (primarily municipal, agricultural, and environmental entities) whose interests frequently are in direct conflict. Although many resource-management issues involve multiple stakeholders and conflict is integral to their discussion, the CALFED experience is unique because of its shared state and federal roles, the magnitude and significance of stakeholder participation, and the complexity of the scientific issues involved.

Defined by lasting more than four weeks - is a common but often challenging clinical scenario. It is important to be aware that diarrhoea means different things to different patients. The evaluation of chronic diarrhoea depends on taking an excellent history and careful physical examination as well as planning investigations thoughtfully. Functional diarrhea ist the most common cause of chronic diarrhea in the developed countries and motility disorders are more common than inflammatory, osmotic or secretory causes. In some cases categorizing patients by their stool characteristics can be helpful in directing further evaluation.

Diarrhea in enterally fed patients: blame the diet?

Science.gov (United States)

Chang, Sue-Joan; Huang, Hsiu-Hua

2013-09-01

Diarrhea has great impact on enteral nutrition. The purpose of this review is to identify the factors leading to diarrhea during enteral nutrition and to provide the published updates on diarrhea prevention through nutritional intervention. Diarrhea in enteral fed patients is attributed to multiple factors, including medications (major contributor), infections, bacterial contamination, underlying disease, and enteral feeding. Diet management can alleviate diarrhea in enteral feeding. High content of fermentable oligosaccharides, disaccharides, and monosaccharides and polyols (FODMAPs) in enteral formula is postulated to induce diarrhea and lower FODMAPs formula may reduce the likelihood of diarrhea in enterally fed patients. Fiber-enriched formula can reduce the incidence of diarrhea and produce short-chain fatty acids for colonocytes. Ingesting prebiotics, nonviable probiotics or probiotic derivatives, and human lactoferrin may provide alternatives for reducing/preventing diarrhea. Enteral feeding is not generally considered the primary cause of diarrhea, which is frequently linked to prescribed medications. When diarrhea is apparent, healthcare members should evaluate the possible risk factors and systematically attempt to eliminate the underlying causes of diarrhea before reducing or suspending enteral feeding. Lower FODMAPs formula, prebiotics, probiotic derivatives, and lactoferrin may be used to manage enteral feeding-related diarrhea.

A serial harvest was conducted every 28 d from 254 to 534 d on feed (DOF) to quantify changes in growth and composition of calf-fed Holstein steers (n = 115, initial body weight (BW) = 449.2 ± 19.9 kg). One-half were supplemented with the β-2 adrenergic agonist zilpaterol hydrochloride (ZH; 8.33 mg/kg 100% dry matter (DM) basis) during the final 20 d followed by a 3-d withdrawal prior to harvest; the remainder was fed a non-ZH control (CON) ration. Five steers were randomly selected and harvested after 226 DOF which served as a reference point for modeling purposes. Fabricated carcass soft tissue was ground, mixed, and subsampled for proximate analysis. Moreover, following the traditional method of rib dissection which includes the 9th, 10th, and 11th rib contained within the IMPS 103 primal, the relationship of carcass chemical composition to 9-10-11 rib composition was evaluated. Carcasses in this investigation had more (P carcasses and rib dissections. Using regression procedures, models were constructed to describe the relationship of rib dissection (RD) composition including separable lean (RDSL), separable fat (RDSF), separable bone (RDSB), ether extract (RDEE), protein (RDP), moisture (RDM), and ash (RDA) with carcass composition. Carcass lean (CL), carcass fat (CF), and carcass bone (CB) were correlated (P carcass, carcass ether extract (CEE), carcass protein (CP), carcass moisture (CM), and carcass ash (CA) were correlated (P ≤ 0.01) with simple r values of 0.75, 0.31, 0.66, and 0.37, respectively. Equations to predict carcass fatness from rib dissection variables and ZH supplementation status were only able to account for 50 and 56%, of the variability of CF and CEE, respectively. Overall, the relationships quantified and equations developed in this investigation do not support use of 9/10/11 rib dissection for estimation of carcass composition of calf-fed Holstein steers.

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

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

Calf health from birth to weaning. III. housing and management of calf pneumonia

Full Text Available Abstract Calfhood diseases have a major impact on the economic viability of cattle operations. A three part review series has been developed focusing on calf health from birth to weaning. In this paper, the last of the three part series, we review disease prevention and management with particular reference to pneumonia, focusing primarily on the pre-weaned calf. Pneumonia in recently weaned suckler calves is also considered, where the key risk factors are related to the time of weaning. Weaning of the suckler calf is often combined with additional stressors including a change in nutrition, environmental change, transport and painful husbandry procedures (castration, dehorning. The reduction of the cumulative effects of these multiple stressors around the time of weaning together with vaccination programmes (preconditioning can reduce subsequent morbidity and mortality in the feedlot. In most studies, calves housed individually and calves housed outdoors with shelter, are associated with decreased risk of disease. Even though it poses greater management challenges, successful group housing of calves is possible. Special emphasis should be given to equal age groups and to keeping groups stable once they are formed. The management of pneumonia in calves is reliant on a sound understanding of aetiology, relevant risk factors, and of effective approaches to diagnosis and treatment. Early signs of pneumonia include increased respiratory rate and fever, followed by depression. The single most important factor determining the success of therapy in calves with pneumonia is early onset of treatment, and subsequent adequate duration of treatment. The efficacy and economical viability of vaccination against respiratory disease in calves remains unclear.

Gait stability is the ability to deal with small perturbations that naturally occur during walking. Changes in motor control caused by pain could affect this ability. This study investigated whether nociceptive stimulation (hypertonic saline injection) in a low back (LBP) or calf (CalfP) muscle affects gait stability. Sixteen participants walked on a treadmill at 0.94ms(-1) and 1.67ms(-1), while thorax kinematics were recorded using 3D-motion capture. From 110 strides, stability (local divergence exponent, LDE), stride-to-stride variability and root mean squares (RMS) of thorax linear velocities were calculated along the three movement axes. At 0.94ms(-1), independent of movement axes, gait stability was lower (higher LDE) and stride-to-stride variability was higher, during LBP and CalfP than no pain. This was more pronounced during CalfP, likely explained by the biomechanical function of calf muscles in gait, as supported by greater mediolateral RMS and stance time asymmetry than in LBP and no pain. At 1.67ms(-1), independent of movement axes, gait stability was greater and stride-to-stride variability was smaller with LBP than no pain and CalfP, whereas CalfP was not different from no pain. Opposite effects of LBP on gait stability between speeds suggests a more protective strategy at the faster speed. Although mediolateral RMS was greater and participants had more asymmetric stance times with CalfP than LBP and no pain, limited effect of CalfP at the faster speed could relate to greater kinematic constraints and smaller effects of calf muscle activity on propulsion at this speed. In conclusion, pain effects on gait stability depend on pain location and walking speed. Copyright © 2015 Elsevier Ltd. All rights reserved.

Full Text Available We studied natality in the Northern Alaska Peninsula (NAP and Southern Alaska Peninsula (SAP caribou (Rangifer tarandus granti herds during 1996-1999, and mortality and weights of calves during 1998 and 1999- Natality was lower in the NAP than the SAP primarily because most 3-year-old females did not produce calves in the NAP Patterns of calf mortality in the NAP and SAP differed from those in Interior Alaska primarily because neonatal (i.e., during the first 2 weeks of life mortality was relatively low, but mortality continued to be significant through August in both herds, and aggregate annual mortality was extreme (86% in the NAP Predators probably killed more neonatal calves in the SAP, primarily because a wolf den (Canis lupus was located on the calving area. Despite the relatively high density of brown bears (Ursus arctos and bald eagles (Haliaeetus leucocephalus, these predators killed surprisingly few calves. Golden eagles (Aquila chrysaetos were uncommon on the Alaska Peninsula. At least 2 calves apparently died from pneu¬monia in the range of the NAP but none were suspected to have died from disease in the range of the SAP. Heavy scav¬enging by bald eagles complicated determining cause of death of calves in both the NAP and SAP.

Full Text Available ABSTRACT: To study the pathogenicity of the Brazilian bovine viral diarrhea virus (BVDV type 1a 241.10 isolate, four calves were intranasally inoculated with a viral suspension containing 107.2 TCID50 mL-1. One calf was left uninoculated and kept in contact with the other calves to investigate viral transmissibility. After inoculation, the animals were monitored daily for clinical signs of infection. The presence of the virus in the blood and nasal secretions was confirmed by virus isolation in cell culture. White blood cells were quantified prior to and every 3 days after infection, and the presence of antibodies was checked every 7 days, starting at day 0 until day 42 post-inoculation (pi. After infection, nasal and ocular serous secretions were observed between days 1 and 5 pi, along with a mild cough from days 2 to 4 pi; however, no severe clinical signs were present. Body temperature was slightly elevated between days 4 and 6 pi. The control calf did not develop any of the signs observed in the infected animals. Cell culture-mediated virus isolation confirmed viremia between days 4 and 8 pi and the presence of the virus in the nasal secretions between days 1 and 10 pi. All infected animals showed a decrease in white blood cell count. Antibodies could be detected from day 14 pi, and these levels remained high until day 35 pi. The control calf had no viremia, viral presence in nasal secretions, or positive serology, indicating the absence of viral transmission. Thus, isolate BVDV 1a 241.10 has low pathogenicity and transmissibility but retains immunosuppressive capacity.

Optimizing calf muscle performance seems to play an important role in minimizing impairments and symptoms after an Achilles tendon rupture (ATR). The literature lacks long-term follow-up studies after ATR that describe calf muscle performance over time. The primary aim was to evaluate calf muscle performance and patient-reported outcomes at a mean of 7 years after ATR in patients included in a prospective, randomized controlled trial. A secondary aim was to evaluate whether improvement in calf muscle performance continued after the 2-year follow-up. Cohort study; Level of evidence, 2. Sixty-six subjects (13 women, 53 men) with a mean age of 50 years (SD, 8.5 years) were evaluated at a mean of 7 years (SD, 1 year) years after their ATR. Thirty-four subjects had surgical treatment and 32 had nonsurgical treatment. Patient-reported outcomes were evaluated with Achilles tendon Total Rupture Score (ATRS) and Physical Activity Scale (PAS). Calf muscle performance was evaluated with single-leg standing heel-rise test, concentric strength power heel-rise test, and single-legged hop for distance. Limb Symmetry Index (LSI = injured side/healthy side × 100) was calculated for side-to-side differences. Seven years after ATR, the injured side showed decreased values in all calf muscle performance tests ( P performance did not continue after the 2-year follow-up. Heel-rise height increased significantly ( P = .002) between the 1-year (10.8 cm) and the 7-year (11.5 cm) follow-up assessments. The median ATRS was 96 (of a possible score of 100) and the median PAS was 4 (of a possible score of 6), indicating minor patient-reported symptoms and fairly high physical activity. No significant differences were found in calf muscle performance or patient-reported outcomes between the treatment groups except for the LSI for heel-rise repetitions. Continued deficits in calf muscle endurance and strength remained 7 years after ATR. No continued improvement in calf muscle performance

To investigate the biologic effects of the calf blood extract on corneal epithelial cells in vitro. The effects on corneal epithelial cells were evaluated after 1, 4, 12, and 24 h of exposure to various concentrations of calf blood extract (3, 5, 8 and 16%). The MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide) assay was performed to measure levels of cellular metabolic activity. The lactate dehydrogenase (LDH) assay was performed to determine the extent of cellular damage. Cellular morphology was examined using phase-contrast microscopy. The scratch wound assay was performed to quantify the migration of corneal epithelial cells. At the 3 and 5% concentrations of calf blood extract, MTT values were similar to those observed in the control group. However, at a concentration of 8 and 16%, cellular metabolic activity was significantly decreased after 4 h of exposure to calf blood extract. After 12 h of exposure to 8 and 16% concentrations of calf blood extract, LDH activity and cellular morphological damage to the corneal epithelial cells were significantly increased. There was no evidence of cellular migration after 12 h exposure to 5% or higher concentration of calf blood extract because of cellular toxicity. Compared with normal corneal epithelial cells, the cellular activity was decreased, and toxicity was increased after over 12 h of exposure to more than 5% concentration of calf blood extract. Further clinical studies will be necessary to determine the optimal concentration and exposure time for the topical application of eye drops containing calf blood extract.

The growth and fertility of a female calf obtained from a frozen-thawed bovine oocyte was assessed. The birth weight of the calf was lower than the mean birth weight of calves from in vitro fertilized embryos (IVF-controls) and calves obtained by artificial insemination (AI-controls). The growth rate of the calf up to 6 months was slower than that of the IVF-controls, but similar to that of the AI-controls. When the calf developed into a heifer (200 kg), she was inseminated with frozen semen and 280 days later delivered a male calf. The chromosoms of this cow were normal. These findings suggest that the growth and fertility of the calf derived from the frozen oocyte are normal.

Full Text Available Human rotavirus (HRV is a leading cause of severe childhood diarrhea, and there is limited vaccine efficacy in the developing world. Neonatal gnotobiotic pigs consuming a prophylactic synbiotic combination of probiotics and rice bran (Pro+RB did not exhibit HRV diarrhea after challenge. Multiple immune, gut barrier protective, and anti-diarrheal mechanisms contributed to the prophylactic efficacy of Pro+RB when compared to probiotics (Pro alone. In order to understand the molecular signature associated with diarrheal protection by Pro+RB, a global non-targeted metabolomics approach was applied to investigate the large intestinal contents and serum of neonatal gnotobiotic pigs. The ultra-high performance liquid chromatography-tandem mass spectrometry platform revealed significantly different metabolites (293 in LIC and 84 in serum in the pigs fed Pro+RB compared to Pro, and many of these metabolites were lipids and amino acid/peptides. Lipid metabolites included 2-oleoylglycerol (increased 293.40-fold in LIC of Pro+RB, p = 3.04E-10, which can modulate gastric emptying, andhyodeoxycholate (decreased 0.054-fold in the LIC of Pro+RB, p = 0.0040 that can increase colonic mucus production to improve intestinal barrier function. Amino acid metabolites included cysteine (decreased 0.40-fold in LIC, p = 0.033, and 0.62-fold in serum, p = 0.014 of Pro+RB, which has been found to reduce inflammation, lower oxidative stress and modulate mucosal immunity, and histamine (decreased 0.18-fold in LIC, p = 0.00030, of Pro+RB and 1.57-fold in serum, p = 0.043, which modulates local and systemic inflammatory responses as well as influences the enteric nervous system. Alterations to entire LIC and serum metabolic pathways further contributed to the anti-diarrheal and anti-viral activities of Pro+RB such as sphingolipid, mono/diacylglycerol, fatty acid, secondary bile acid, and polyamine metabolism.

Probiotics and Antibiotic-Associated Diarrhea and Clostridium difficile Infection

Science.gov (United States)

Surawicz, Christina M.

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

Porcine epidemic diarrhea virus (PEDV), an enteric coronavirus, is the causative agent of porcine epidemic diarrhea (PED) that damages intestinal epithelial cells and results in severe diarrhea and dehydration in neonatal suckling pigs with up to 100% mortality. The oral vaccine route is reported as a promising approach for inducing protective immunity against PEDV invasion. Furthermore, dendritic cells (DCs), professional antigen-presenting cells, link humoral and cellular immune responses for homeostasis of the intestinal immune environment. In this study, in order to explore an efficient oral vaccine against PEDV infection, a mucosal DC-targeting oral vaccine was developed using Lactobacillus casei to deliver the DC-targeting peptide (DCpep) fused with the PEDV core neutralizing epitope (COE) antigen. This probiotic vaccine could efficiently elicit secretory immunoglobulin A (SIgA)-based mucosal and immunoglobulin G (IgG)-based humoral immune responses via oral vaccination in vivo. Significant differences ( p targeting peptide fused with PEDV COE antigen. This mucosal DC-targeting oral vaccine delivery effectively enhances vaccine antigen delivery efficiency, providing a useful strategy to induce efficient immune responses against PEDV infection.

2009-11-01

The calf-raise test is used by clinicians and researchers in sports medicine to assess properties of the calf muscle-tendon unit. The test generally involves repetitive concentric-eccentric muscle action of the plantar-flexors in unipedal stance and is quantified by the number of raises performed. Although the calf-raise test appears to have acceptable reliability and face validity, and is commonly used for medical assessment and rehabilitation of injuries, no universally acceptable test parameters have been published to date. A systematic review of the existing literature was conducted to investigate the consistency as well as universal acceptance of the evaluation purposes, test parameters, outcome measurements and psychometric properties of the calf-raise test. Nine electronic databases were searched during the period May 30th to September 21st 2008. Forty-nine articles met the inclusion criteria and were quality assessed. Information on study characteristics and calf-raise test parameters, as well as quantitative data, were extracted; tabulated; and statistically analysed. The average quality score of the reviewed articles was 70.4+/-12.2% (range 44-90%). Articles provided various test parameters; however, a consensus was not ascertained. Key testing parameters varied, were often unstated, and few studies reported reliability or validity values, including sensitivity and specificity. No definitive normative values could be established and the utility of the test in subjects with pathologies remained unclear. Although adapted for use in several disciplines and traditionally recommended for clinical assessment, there is no uniform description of the calf-raise test in the literature. Further investigation is recommended to ensure consistent use and interpretation of the test by researchers and clinicians.

Two experiments were conducted to examine the influence of protein and virginiamycin (VM) supplementation on feedlot growth performance, digestion, and metabolizable AA (MAA) supply of calf-fed Holstein steers. Growth performance and dietary energetics were evaluated in 120 Holstein steers (127 ± 9 kg). During the initial 112-d feeding period, a steam-flaked corn-based diet was balanced to meet either 100% (MAB) or 87% (UREA) of MAA requirements. Diets were supplemented with or without 22.5 mg/kg VM in a 2 × 2 factorial arrangement. Subsequently (d 112 to 308), all steers received the UREA diet with or without VM. During the initial 112-d, MAB increased ADG, G:F, and dietary NE ( 0.10) across initial supplementation treatments. Overall (d 1 to 308), MAB did not affect ADG ( > 0.10) but enhanced G:F efficiency ( = 0.03) and dietary NE ( = 0.05). During the initial 112-d period and through the remainder of the experiment, VM increased G:F ( 0.10) on ruminal digestion of OM, NDF, starch, microbial efficiency, or total tract digestion of OM and NDF. The MAB increased indispensable AA flow to the small intestine ( 0.10) total tract N digestion. Extrapolating from AA supplies in the metabolism study, MAB satisfied indispensable AA requirements during the initial 112-d period, whereas the UREA diet met 73.5% and 79.2% of methionine and lysine requirements, respectively. During the subsequent periods (d 112 to 308) indispensable AA supplies exceeded theoretical requirements. We conclude that enhancements in energy utilization when diets are balanced to meet MAA requirements of calf-fed Holstein steers during the initial 112-d feedlot period remain appreciable throughout time on feed. Virginiamycin enhanced efficiency of energy utilization throughout the feedlot growing-finishing period.

Antibody transferred from the blood to the gastrointestinal tract and its role in enteric immunity of neonatal calves

High passive blood immunoglobulin concentrations are associated with decreased infectious enteric disease mortality in neonatal calves. Passive immunoglobulin transferred from the blood to the gastrointestinal tract may explain this protection. To measure the rate at which immunoglobulin G 1 (IgG 1 ) is transferred to the gastrointestinal tract, 125 I-labelled bovine IgG 1 anti-DNP antibody was administered to calves by intravenous injection. The clearance rate of 125 I-IgG 1 from the blood was measured and compared to the rate of 125 I-IgG 1 appearance in the gastrointestinal tract, as measured (1) by the rate of fecal 125 I-IgG 1 excretion, and (2) by the amount of 125 I-IgG 1 in the gastrointestinal tract of calves at necropsy. Rotavirus antibody titers in the gastrointestinal contents of 5- and 10-days-old calves correlated with the calves' serum passive rotavirus antibody titers, and were increased in proportion to the amount of colostral antibody fed on the first day of life. In contrast, when colostral rotavirus antibody was fed to 48-hour-old calves, when absorption of passive immunoglobulin does not occur, there was no measurable increase in antibody in the intestine 5 days later. Intestinal antibody in the 5- and 10-day-old calves therefore resulted from blood antibody transferred to the gastrointestinal tract. Rotavirus antibody administered to calves by parenteral injection protected them from infection and diarrhea after rotavirus challenge. These results indicate that passive blood IgG enters the calf gastrointestinal tract, where it contributes to intestinal immunity

Dyskospondylitis and paravertebral abscesses in a calf

A case of progressive spastic paraparesis due to a dyskospondylitis at the level of T9-T10 is described in a four-month old Holstein female calf. The calf was recumbent, but bright, alert and willing to suckle. Despite repeated attempts, the calf was not able to assume the sternal recumbency. The radiological findings were decisive for the in life diagnosis. Spinal radiography of the thoraco-lumbar region revealed lysis and collapse of T9 and T10 vertebral bodies; irregular proliferative new bone was evident. Lumbo-sacral myelography showed a narrowing and dorsal displacement of the ventral contrast column at the same spinal level, indicating a severe ventral extradural compression of the spinal cord. At the level of the thoracic cavity, a 20 x 15 cm diameter opacity extending ventrally to T8-T13 and caudo-dorsally to the heart was also evident. At gross necroscopy, two approximately 15 cm diameter encapsulated paravertebral abscesses were evident in the thoracis cavity just below the spinal column. A pure culture of Fusobacterium necrophorum was obtained from them. A saggital section of the spine showed an erosive suppurative process of T9 and T10 vertebral bodies that provoked the compression of the thoracic tract of the spinal cord [it

Diarrhea is a common problem in critically ill patients. Our patients are fed a high-carbohydrate enteral formula. We hypothesized that diarrhea in our patients may be related to the osmotic effects of unabsorbed carbohydrate in the small intestine and colon. We studied 19 patients, 3 months to 17 years, with burns >40% total body surface area. Each subject was studied weekly for up to 4 weeks postburn. Breath H2 concentration was measured. For the 24-hour period before the breath H2 measurement, the enteral carbohydrate intake, stool volume, and total enteral fluid volume were recorded. At each of several weekly intervals for each subject, the times when stool volume and enteral carbohydrate intake were each maximal were noted. Maximal stool volume ranged from 12 to 69 mL/kg/d. At the time point of maximal carbohydrate intake, diarrhea (stool volume >10 mL/kg/d) occurred in 18 of 19 patients, and maximal stool volume occurred in 10 of 19. Breath H2 concentration (ppm/5% CO2; mean +/- SEM) was 5.5 +/- 3.5 at the time of maximal carbohydrate intake, and was 25 +/- 20 at maximal stool volume. There were no correlations among breath H2 concentration, stool volume, enteral fluid intake, and enteral carbohydrate intake. Almost all the subjects had diarrhea over several weeks postburn. The lack of correlation of either carbohydrate intake or breath H2 with stool volume suggests that diarrhea in these patients may be caused by factors other than carbohydrate malabsorption. These data do not support altering nutrition support because of watery diarrhea.

Full Text Available Objective of this study was to investigate the economic impact of mortality of pre-weaned calves on dairy cattle enterprise in Kuwait. Cost/benefit analysis model was applied to two different situations: in the first situation, a baseline scenario, field survey data without intervention using 1,280 newborn calves was used in first calving season. In the second situation, the intervention scenario (improved management, 665 newborn calves were used in second calving season during the following year. Calving seasons extended for 7 months from September to March. Calf performance studies were conducted from birth to weaning. Economic model was constructed on Microsoft Excel and used to evaluate the impact of calf mortality on calf enterprise. Results showed that gross margins increased from 13 to 35% as a result of implementation of intervention measures during the second calving season over baseline scenario. A significant correlation between increased veterinary expenses and an increase in revenues (r2 = 0.65, P<0.05 was observed. If the intervention measures such as colostrum feeding, nutrition and hygiene had not been implemented, the farms would have lose income from 12 to 51% of the gross revenues. Net income was influenced by costs of feeds, veterinary services and laborers. Discounted cash flow studies on a whole farm basis revealed that the impact of interventions was small (0-3%. Calf mortality could not be isolated from whole farm for assessing its impact on dairy farm economics. Economic studies demonstrated the cost/benefits of using the improved techniques of calf rearing.

We previously isolated a porcine epidemic diarrhea virus (PEDV) strain, PC177, by blind serial passaging of the intestinal contents of a diarrheic piglet in Vero cell culture. Compared with the highly virulent U.S. PEDV strain PC21A, the tissue culture-adapted PC177 (TC-PC177) contains a 197-amino-acid (aa) deletion in the N-terminal domain of the spike (S) protein. We orally inoculated neonatal, conventional suckling piglets with TC-PC177 or PC21A to compare their pathogenicities. Within 7 days postinoculation, TC-PC177 caused mild diarrhea and lower fecal viral RNA shedding, with no mortality, whereas PC21A caused severe clinical signs and 55% mortality. To investigate whether infection with TC-PC177 can induce cross-protection against challenge with a highly virulent PEDV strain, all the surviving piglets were challenged with PC21A at 3 weeks postinoculation. Compared with 100% protection in piglets initially inoculated with PC21A, 88% and 100% TC-PC177- and mock-inoculated piglets had diarrhea following challenge, respectively, indicating incomplete cross-protection. To investigate whether this 197-aa deletion was the determinant for the attenuation of TC-PC177, we generated a mutant (icPC22A-S1Δ197) bearing the 197-aa deletion from an infectious cDNA clone of the highly virulent PEDV PC22A strain (infectious clone PC22A, icPC22A). In neonatal gnotobiotic pigs, the icPC22A-S1Δ197 virus caused mild to moderate diarrhea, lower titers of viral shedding, and no mortality, whereas the icPC22A virus caused severe diarrhea and 100% mortality. Our data indicate that deletion of this 197-aa fragment in the spike protein can attenuate a highly virulent PEDV, but the virus may lose important epitopes for inducing robust protective immunity. IMPORTANCE The emerging, highly virulent PEDV strains have caused substantial economic losses worldwide. However, the virulence determinants are not established. In this study, we found that a 197-aa deletion in the N-terminal region

Pathophysiology, Evaluation, and Management of Chronic Watery Diarrhea

2016-01-01

Chronic watery diarrhea poses a diagnostic and therapeutic challenge and is often a disabling condition for patients. Although acute diarrhea is likely to be caused by infection, the causes of chronic diarrhea (more than 4 weeks in duration) are more elusive. We review on the pathophysiology, diagnosis, and treatment of chronic diarrhea. Drawing on recent insights into the molecular mechanisms of intestinal epithelial transport and barrier function, we discuss how diarrhea can result from a decrease in luminal solute absorption, an increase in secretion, or both, as well as derangements in barrier properties. We also describe the various extra-epithelial factors that activate diarrheal mechanisms. Finally, clinical evaluation and tests used in assessment of patients presenting with chronic diarrhea are reviewed, and an algorithm guiding therapeutic decisions and pharmacotherapy is presented.

Escherichia coli is one of the main etiological agents of neonatal calf diarrhea (NCD). The objective of this study was to assess the presence of virulence genes, genetic diversity, and antibiotic resistance mechanisms in E. coli associated with NCD in Uruguay. PCR was used to assess the presence of intimin, Shiga-like toxin, and stable and labile enterotoxin genes. Resistance to fluoroquinolones and oxyimino-cephalosporins was estimated on Müller-Hinton agar plates. Further antibiotic disc-diffusion tests were performed to assess bacterial multi-resistance. The presence of PMQR, ESBL, MCR-1, and integron genes was evaluated. Isolates were typed using ERIC-PCR, and 20 were selected for MLST, adhesion to Hep-2 cells, in vitro biofilm formation, and eukaryotic cytotoxicity. The prevalence of ETEC genes was lower than 3% in each case (estA and elt). Six isolates were EPEC (eae+) and 2 were EHEC/STEC (eae+/stx1+). The results of a diversity analysis showed high genetic heterogenicity among isolates. Additionally, different sequence types, including ST10, ST21, and ST69, were assigned to selected isolates. Thirty-six percent (96/264) of the isolates were fluoroquinolone-resistant, with 61/96 (63.5%) being multidrug-resistant. Additionally, 6 were oxyimino-cephalosporin-resistant. The qnrB, qnrS1, and bla CTX-M-14 genes were detected, whereas no isolates carried the mcr-1 gene. Isolates had the ability to adhere to Hep-2 cells and form biofilms. Only 1 isolate expressed toxins in vitro. E. coli from NCD cases in Uruguay are very diverse, potentially virulent, and may interact with eukaryotic cells. Zoonotic potential, together with resistance traits and the presence of horizontal transfer mechanisms, may play a significant role in infections caused by these microorganisms.

Bile acids in radiation-induced diarrhea

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

Post-irradiation diarrhea

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

The foundation of recommended diarrhea management in young children is increased fluids and continued feeding. This increase in fluids is necessary to replace those lost during diarrhea and ultimately prevent dehydration. There may be an opportunity to prevent deaths in children under five by discouraging the practice of reducing or curtailing fluids during diarrhea episodes across different settings worldwide. We quantify and describe the extent of fluid curtailment in children with diarrhea in a selection of countries (Burkina Faso, Democratic Republic of Congo, Ethiopia, Nigeria, Tanzania, and Uganda) with high burden of diarrhea-related mortality with national cross sectional survey data. We examine the practice of fluid curtailment in these countries and its relationship to child and household traits and to characteristics of diarrhea management. The prevalence of fluid curtailment among children under five with diarrhea is strikingly high in these countries: 55 % in Nigeria, 49 % in Ethiopia, 44 % in Uganda, 37 % in Tanzania, 36 % in DR Congo and 32 % in Burkina Faso. Fluid curtailment is associated with giving less food, potentially worsening the impact of this harmful practice. Children who were reported to have had fluids curtailed during diarrhea episodes were also 3.51 (95 % confidence, 2.66 - 4.64) times more likely to be reported to have food withheld (α = 0.05; p water source. Children of poorer or less educated mothers and those living in rural areas are more likely to have curtailed fluids, compared to children of less poor or more educated mothers, or those living in urban areas. The harmful practice of curtailing fluids for a child with diarrhea is highly prevalent, representing an increased risk of dehydration and complications due to diarrhea, including death, especially for children in specific subgroups.

Calf hypertrophy is a common feature in Becker muscular dystrophy (BMD), and it is still debated to which extent fatty degeneration or true muscle hypertrophy account for it. We wanted to investigate the relative contribution of these two components using a simple image analysis approach and their possible correlation with disease severity. Twenty-nine BMD patients' MRI scans were analyzed. A semiquantitative visual score assessing fatty replacement of calf muscles (calf MRI score, CMS) was calculated and correlated with the cross sectional area (CSA) of lower leg posterior compartment muscles, digitally measured on acquired images. The correlation between CSA and CMS was not significant. CMS in contrast correlated with disease severity (p<0.001) while CSA did not (p=0.969). In BMD, a major contribution to calf hypertrophy is provided by real muscle hypertrophy rather than by fatty degeneration. CMS appears to be a potential surrogate marker of disease severity.

Porcine epidemic diarrhea virus (PEDV) causes acute diarrhea, vomiting, dehydration, weight loss, and high mortality rate in neonatal piglets. Porcine epidemic diarrhea (PED) has been reported in Europe, America, and Asia including Thailand. The disease causes substantial losses to the swine industry in many countries. Presently, there is no effective PEDV vaccine available. In this study, we developed a plant-produced monoclonal antibody (mAb) 2C10 as a prophylactic candidate to prevent the PEDV infection. Recently, plant expression systems have gained interest as an alternative for the production of antibodies because of many advantages, such as low production cost, lack of human and animal pathogen, large scalability, etc. The 2C10 mAb was transiently expressed in Nicotiana benthamiana and lettuce using geminiviral vector. After purification by protein A affinity chromatography, the antibody was tested for the binding and neutralizing activity against PEDV. Our result showed that the plant produced 2C10 mAb can bind to the virus and also inhibit PEDV infection in vitro . These results show excellent potential for a plant-expressed 2C10 as a PEDV prophylaxis and a diagnostic for PEDV infection. Georg Thieme Verlag KG Stuttgart · New York.

Update on traveler's diarrhea.

Strum, W B

1988-07-01

Traveler's diarrhea affects a substantial number of travelers to high-risk areas of the world. The key to controlling this troublesome disease is prevention. The most important preventive measures depend on educating patients to consume only safe foods and pure water. Physicians cannot overemphasize the importance of avoiding high-risk foods and of boiling water if a safe water supply is not available. Prophylactic medications are a secondary consideration and should be prescribed with discretion. In most cases, diarrhea is mild and self-limited, requiring only fluid and electrolyte replacement and perhaps an antidiarrheal agent. In moderate to severe cases, the addition of an antimicrobial agent may be of benefit. Until an efficacious polyvalent vaccine is developed, caution and common sense, together with discretionary dietary and hygienic practices, are the best defenses against traveler's diarrhea. The ultimate solution is greatly improved sanitation and personal hygiene, especially in high-risk countries. However, only dreamers will consider waiting for this transformation to occur.

Woodland caribou calf recruitment in relation to calving/post-calving landscape composition

Directory of Open Access Journals (Sweden)

Sara C. McCarthy

2011-04-01

Full Text Available Since the 1990s, Newfoundland’s woodland caribou (Rangifer tarandus caribou population has declined by an estimated 66%. Low calf recruitment has been associated to the decline, possibly triggered by increasing calf predation and/or decreasing resources. To investigate the role of landscape composition in this system, we studied the yearly (2005-2008 calving/post-calving range (CPCR of 104 satellite-collared females belonging to six herds. We mapped nine disturbance factors (e.g. roads, logging, etc, as well as vegetation cover types (e.g. coniferous, deciduous forests, etc, and determined the total area they occupied within CPCRs yearly for each herd. Using an information theoretic approach, we assessed the model that best explained variation in recruitment using these components. Based on corrected Akaike Information Criterion, the model that best explained variation in calf recruitment included total disturbance and deciduous forest area, both showing the expected negative relationship with calf recruitment. Other landscape variables among the models with ΔAICc < 2 were mixed forest, also with a suggested negative relationship, and barrens and wetlands with a significant positive trend. This study highlights the need to minimize total disturbance footprint and account for resulting changes in forest composition within CPCRs during land use planning. Expanding forestry operations and road infrastructure in critical woodland caribou habitat across Canada may additionally contribute to habitat loss via fragmentation. This in turn, may lead to range recession beyond the initial local avoidance footprint. We see the possibility of using calf recruitment models based on landscape parameters, among others, to predict the impact of new industrial developments on calf recruitment.

Full Text Available From May to August 1999, we evaluated 401 patients from a pediatric hospital of Havana City. One group was composed of 113 patients with diarrhea admitted to the Gastroenterology ward and a second consisted of 288 patients without diarrhea, admitted for other reasons, and hospitalized within the same time period. Three stool samples were collected from each child and were examined using three parasitological techniques. When we compared the frequency of parasite species between both groups, we found Cryptosporidium spp. and Cyclospora cayetanensis, only in the group of children with diarrhea (P 0.05. In addition, in those children infected with Cryptosporidium, the diarrhea had a more prolonged duration (P < 0.01, while those infected with Cyclospora, the abdominal cramps or pain, and acute diarrhea were more frequently detected (P < 0.01. Our results showed that emerging intestinal coccidia are pathogens strongly associated in this group of children with diarrhea.

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

Control of radiation-induced diarrhea with cholestyramine

International Nuclear Information System (INIS)

Heusinkveld, R.S.; Manning, M.R.; Aristizabal, S.A.

1978-01-01

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

Patients seeking help from gastroenterologist have frequent complaints of changes in the quality and quantity of stool as well in the frequency of bowel movements. Definition of diarrhea includes: more than three bowel movements daily, more than 200 grams of the stool daily, and its water content exceeding 75-85%. Diarrhea lowers the quality of life and can be a sign of organic disease. Its course can be acute and chronic. According to the pathomechanism, diarrheas can be divided into four different types: exudative (inflammatory), osmotic, dismotility and secretory. Acute diarrheas are usually infective, and sometimes they result in very serious conditions. Their course runs from a few days to a couple of weeks. If diarrhea persists more than four weeks, it is the chronic variant and it justifies gastroenterological examination. During the evaluation, we have to think of endocrine, autoimmune, allergic, postoperative states and the side effect of medications beside primer gastroenterological causes. To differentiate from a number of wide scale of clinical pictures and to reach the correct diagnosis, we are aided by the characteristics of diarrhea, the accompanying symptoms, laboratory values and invasive examinations. With the present summary, we would like to give a guide to the practicing physicians, mainly with a symptom-oriented approach.

In developing countries where diarrhea is a major health problem, mothers are often ignorant about the cause and management of the disease and tend to restrict fluid intake instead of taking steps to prevent dehydration. 300 mothers of children hospitalized in Rewa, India, were interviewed with a pretested questionnaire on their diarrhea knowledge. 74.3% were rural and 80.6% were aged 20-30 years. 70% were illiterate and belonged to the upper lower or lower middle class. Causes of diarrhea cited by the mothers included teething (64.3%), evil eye (46%), contact with another case (36.6%), malnutrition (28.3), worm infestation (22.6%), eating mud (18.6%), mother's food habits (17.6%), eating sweets (17.3%), dirty water (15.3%), hot/cold foods (10.6%), change of food (8.3), and dirty environment (6%). During diarrhea, 266 mothers allowed breast milk, 118 pulses and rice gruel, 104 diluted cow's milk, 57 undiluted cow's milk, 25 boiled pulses water, 23 boiled rice water, 16 banana, 13 oral rehydration solution, 10 a whole diet, 8 tea, and 7 curd. Half of the mothers considered passage of liquid stools 3-5 times a day as diarrhea. Only 3% of the mothers listed dehydration as an important complication of the disease. Of the mothers using oral rehydration therapy, the fluid was often not reconstituted properly, and inadequate amounts were administered. Improved health education for mothers, with information on general hygiene, adequate diet during illness, and the use of oral rehydration solution in diarrhea would reduce diarrhea deaths.

Calf blood flow (Ft) by thermal measurement was accounted for by the equation of the form Ft=(CdT*d+Ho-Mb)/rho sub(b)c su b(D) (Ta-Td), where Cd is thermal capacitance of the calf compartment, T*d is the change of calf tissue temperature, Ta is arterila blood temperature, Td is calf tissue temperature, Ho is the heat dissipation from the compartment to the environment, Mb is estimated metabolism of the calf tissue and rho sub(b)c sub(b) is the product of density and specific heat of blood. The healthy men were chosen for the experiments. Total calf blood flow was 2.53+-1.31ml/(min-100ml calf), and muscle blood flow was 2.63+-1.69ml/(min- 100ml muscle) and skin blood flow 7.19+-3.83ml/(min-100ml skin) measured by 133 Xe clearance. On the basis of the results, an estimate has been made of the proportions of the calf volume which can be ascribed to skin and muscle respectively. Estimated muscle and skin blood flow were correlated with total calf blood flow(r=0.98). (author)

To search the pathophysiological mechanism of diarrhea based on daily stool weights, fecal electrolytes, osmotic gap and pH. Seventy-six patients were included: 51 with microscopic colitis (MC) (40 with lymphocytic colitis (LC); 11 with collagenous colitis (CC)); 7 with MC without diarrhea and 18 as a control group (CG). They collected stool for 3 d. Sodium and potassium concentration were determined by flame photometry and chloride concentration by titration method of Schales. Fecal osmotic gap was calculated from the difference of osmolarity of fecal fluid and double sum of sodium and potassium concentration. Fecal fluid sodium concentration was significantly increased in LC 58.11+/-5.38 mmol/L (Pdiarrhea compared to fecal osmotic gap. Seven (13.3%) patients had osmotic diarrhea. Diarrhea in MC mostly belongs to the secretory type. The major pathophysiological mechanism in LC could be explained by a decrease of active sodium absorption. In CC, decreased Cl/HCO3 exchange rate and increased chloride secretion are coexistent pathways.

Although highly prevalent and painful, night-time calf muscle cramping is poorly understood, and no treatment has shown consistent efficacy or safety. One hundred sixty adults were recruited from New South Wales, Australia, including 80 who had night-time calf cramping at least once per week and 80 age- and gender-matched adults who did not. Participants were assessed using reliable tests of lower limb strength, flexibility, morphometrics, circulation, and sensation, and were questioned about health and lifestyle factors, diet, medications, exercise, symptomatology, sleeping habits, and footwear. Conditional logistic regression identified 3 factors independently associated with night-time calf muscle cramps: muscle twitching (OR 4.6, 95% CI 1.6-15.5, P = 0.01); lower limb tingling (OR 4.1, 95% CI 1.6-10.3, P = 0.003); and foot dorsiflexion weakness (OR 1.02, 95% CI 1.01-1.03, P = 0.002), which represented other measures of lower limb weakness in the model. Night-time calf muscle cramps were associated with markers of neurological dysfunction and potential musculoskeletal therapeutic targets. Copyright © 2012 Wiley Periodicals, Inc., a Wiley company.

Full Text Available Background: Flexibility helps with injury prevention, the reduction of soreness following a workout, and a general sense of well-being. There are different stretching techniques and protocols for improvements in calf extensibility and flexibility. The purpose of the study was to investigate the effectiveness of two techniques i.e. CYCLIC and PNF stretching which improves calf flexibility. This study was done to find the effectiveness of calf Cyclic and PNF stretching technique to improve calf flexibility. Methods: 30 subjects with age group 21-22 years were randomly allocated to 2 groups equally. Group 1(n=15 were given CYCLIC and group 2(n=15 were given PNF stretching technique. Plantar flexion was used to measure the calf tightness which was done before and after the treatment. Treatment was given for 7 days and on the 7th day the calf tightness was again measured. Results: The mean difference of the CYCLIC is 4.6 and mean difference of PNF is 4.7 which indicate that CYCLIC and PNF both are effective to improve calf flexibility but PNF is more effective than CYCLIC to improve calf flexibility. Conclusion: The neurophysiological basis of PNF, stating that the excitatory efficient of the neuromuscular spindle or the inhibitory afferent of the Golgi tendon organ (GTO or both are responsible for the effects. During PNF stretch and isometric contraction of stretched agonists for extended period may cause activation of its neuromuscular spindle. The increase in tension created during the isometric contraction of the pre – lengthened agonist contracts concentrically. Both the fascia & the spindle of the agonist adjust to the nearly lengthened position. These impulses travel via causing post synaptic inhibition of the motor neuron to agonist increasing the tension from the GTO. These impulses can override the impulses coming from the neuromuscular spindles arousing the muscle to reflexly resist to the change in length, thus helping in lengthening

Travelers' diarrhea.

On the average, one-fourth of North Americans visiting developing countries experience a self-limited diarrheal illness that interferes with holiday or business activities. Recent work suggests that these episodes are caused by a small inoculum of enteropathogenic Escherichia coli which are common in the country visited and rare in the country of origin. Neither antimicrobial treatment nor anti-diarrheal agents have proven benefit once the illness has begun. Despite its frequent use, iodochlorhydroxyquin has not been shown in double blind studies to be effective as a preventive agent, and may be dangerous. The status of furazolidone for prevention of tourist diarrhea is questionable. Both neomycin sulfate and phythalylsulfathiazole have demonstrated efficacy as chemoprophylactics in Mexico. However, their use should be restricted to limited types of travel and travelers. General admonitions concerning avoidance of certain ingestibles are recommended; despite questionable value in preventing travelers' diarrhea such precautions may prevent more serious gastrointestinal illness.

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

Background: Diarrhea is a leading cause of child mortality worldwide. Rotavirus is one of the most common causes of severe diarrhea and dehydration in children. Authors reviewed epidemiological and clinical data of the rotavirus diarrhea in Kosovo. Methods: This is a prospective study carried between January 1st and December 31st 2011. All data, comprising demographics, nutrition, clinical presentation, laboratory findings, management and outcome of the rotavirus diarrhea are collected on the specially designed form. Results: 116 children with rotavirus diarrhea are included in the study. The majority boys (74.4%) and children aged 0 – 12 months (82.75%). Mean age of children in the study was 16.38 months. Almost every third child in the study was hypotrophic (29.2%). More than half of the infants (55.2%) were on mixed food, somewhat more than every third was breast feeding (36.45%), and every twelfth (8.33%) was on artificial milk (animal or formula). Apart from diarrhea, present in all patients, vomiting (97.41%) and fever (43.96%) were characteristics of the clinical presentation of the diarrhea. Two thirds of the children had mild grade dehydration (70.7%). All patients recovered with no sequels. Conclusion: Rotavirus continues to be responsible for a significant portion of acute diarrhea in Kosovo. Clinical features, epidemiological data and the agglutination test are safe enough to establish the diagnosis. Treated correctly rotavirus diarrhea has a favorable outcome. PMID:25568634

Antibody transferred from the blood to the gastrointestinal tract and its role in enteric immunity of neonatal calves

Energy Technology Data Exchange (ETDEWEB)

Besser, T.E.

1986-01-01

High passive blood immunoglobulin concentrations are associated with decreased infectious enteric disease mortality in neonatal calves. Passive immunoglobulin transferred from the blood to the gastrointestinal tract may explain this protection. To measure the rate at which immunoglobulin G/sub 1/ (IgG/sub 1/) is transferred to the gastrointestinal tract, /sup 125/I-labelled bovine IgG/sub 1/ anti-DNP antibody was administered to calves by intravenous injection. The clearance rate of /sup 125/I-IgG/sub 1/ from the blood was measured and compared to the rate of /sup 125/I-IgG/sub 1/ appearance in the gastrointestinal tract, as measured (1) by the rate of fecal /sup 125/I-IgG/sub 1/ excretion, and (2) by the amount of /sup 125/I-IgG/sub 1/ in the gastrointestinal tract of calves at necropsy. Rotavirus antibody titers in the gastrointestinal contents of 5- and 10-days-old calves correlated with the calves' serum passive rotavirus antibody titers, and were increased in proportion to the amount of colostral antibody fed on the first day of life. In contrast, when colostral rotavirus antibody was fed to 48-hour-old calves, when absorption of passive immunoglobulin does not occur, there was no measurable increase in antibody in the intestine 5 days later. Intestinal antibody in the 5- and 10-day-old calves therefore resulted from blood antibody transferred to the gastrointestinal tract. Rotavirus antibody administered to calves by parenteral injection protected them from infection and diarrhea after rotavirus challenge. These results indicate that passive blood IgG enters the calf gastrointestinal tract, where it contributes to intestinal immunity.

The use of Brahman in cow-calf production offers some adaptation to the harsh characteristics of endophyte-infected tall fescue. Criollo breeds, such as the Romosinuano, may have similar adaptation. The objectives were to estimate genetic effects in Romosinuano, Angus, and crossbred cows for their weights, weights of their calves, and ratios (calf weight:cow weight and cow weight change:calf weight gain) across lactation and to assess the influence of forage on traits and estimates. Cows ( = 91) were bred to Charolais bulls after their second parity. Calves ( = 214) were born from 2006 to 2009. Cows and calves were weighed in early (April and June), mid- (July), and late lactation (August and October). Animal was a random effect in analyses of calf data; sire was random in analyses of cow records and ratios. Fixed effects investigated included calf age, calf sex, cow age-year combinations, sire breed of cow, dam breed of cow, and interactions. Subsequent analyses evaluated the effect of forage grazed: endophyte-free or endophyte-infected tall fescue. Estimates of maternal heterosis for calf weight ranged from 9.3 ± 4.3 to 15.4 ± 5.7 kg from mid-lactation through weaning ( cow) were -6.8 ± 3.0 and -8.9 ± 4.2 kg for weights recorded in April and June. Calf weights and weight gains from birth were greater ( cows grazing endophyte-free tall fescue except in mid-summer. Cow weight change from April to each time was negative for Angus cows and lower ( Cows grazing endophyte-free tall fescue were heavier ( cows had the lowest ( cow weight change:calf weight gain, indicating an energy-deficit condition. Cows grazing endophyte-free tall fescue had more negative ( cow weight, 7.9 ± 3.0 to 15.8 ± 5.0 kg for cow weight change, and 0.07 ± 0.03 to 0.27 ± 0.1 for cow weight change:calf weight gain.

Looking for evidence that personal hygiene precautions prevent traveler's diarrhea.

Shlim, David R

2005-12-01

In the 50 years during which traveler's diarrhea has been studied, it has always been assumed that personal hygiene precautions can prevent or reduce the likelihood of developing traveler's diarrhea. However, 7 of 8 studies that specifically addressed this issue showed no correlation between the types of food selected and the risk of acquiring traveler's diarrhea. The eighth study showed a correlation between a few dietary mistakes and a decreased risk of acquiring traveler's diarrhea. A further increase in the number of dietary mistakes, however, did not continue to increase the risk of acquiring traveler's diarrhea. Personal hygiene precautions, when performed under the direct supervision of an expatriate operating his or her own kitchen, can prevent traveler's diarrhea, but poor restaurant hygiene in most developing countries continues to create an insurmountable risk of acquiring traveler's diarrhea.

Acute diarrhea continues to be a leading cause of morbidity, hospitalization and mortality worldwide and probiotics have been proposed as a complementary therapy in the treatment of acute diarrhea. Regarding the treatment of acute diarrhea, a few probiotics including Saccharomyces boulardii seem to be promising therapeutic agents. We performed a systematic review and meta-analysis regarding the use of S. boulardii in the treatment of acute infectious diarrhea with relevant studies that searched with the PubMed, Embase, Scopus, Google Scholar, the Cochrane Controlled Trials Library, and the Cochrane Database of Systematic Reviews through October 2011. This review describes the effects of S. boulardii on the duration of diarrhea, the risk of diarrhea during the treatment (especially at the third day) and duration of hospitalization in patients with acute infectious diarrhea. This review also focused on the potential effects of S. boulardii for acute infectious diarrhea due to different etiological causes. S. boulardii significantly reduced the duration of diarrhea approximately 24 h and that of hospitalization approximately 20 h. S. boulardii shortened the initial phase of watery stools; mean number of stools started to decrease at day 2; moreover, a significant reduction was reported at days 3 and 4. This systematic review and meta-analysis of the efficacy of S. boulardii in the treatment of acute infectious diarrhea show that there is strong evidence that this probiotic has a clinically significant benefit, whatever the cause, including in developing countries. Therefore, with S. boulardii, the shortened duration of diarrhea and the reduction in hospital stay result in social and economic benefits.

Full Text Available Introduction. The most notable problem of the widespread use of antibiotics is the changes in microbial ecology, imbalance of intestinal biocenosis, the appearance of antibiotic-resistant strains of microorganisms with pathogenic properties and due to this the pathological changes in the intestine that cause symptoms of digestive disorders in patients with antibiotic-associated diarrhea. Objective. To identify the symptoms of malabsorption in order to improve early diagnosis of antibiotic-associated diarrhea in children. Materials and methods. The object of the study were 116 patients treated with antibiotics, aged 6 months to 18 years. The examination of children included clinical, biochemical, bacteriological, immunoenzyme, immunochromatographic, instrumental, mathematical methods. Results. In the development of diarrhea in patients with negative test on clostridial toxins, such cases were qualified as idiopathic antibiotic-associated diarrhea, with positive — like intestinal Clostridium difficile infection. The study revealed significant differences in scatological indices between the children with acute idiopathic and antibiotic-associated diarrhea caused by clostridial infection. During microscopic and biochemical studies of feces, we have revealed symptomatic signs of impaired digestion and absorption of fats and carbohydrates, which manifested by clinical symptoms of malabsorption. All children with antibiotic-associated diarrhea are characterized by increased concentrations of carbohydrates in feces. Signs of digestive disorders with the development of malabsorption of lipids were detected n children with antibiotic-associated diarrhea, primarily caused by Clostridium difficile infection. Conclusions. Maldigestion and lipid and carbohydrate absorption, as well as symptoms of inflammation in the intestines (leukocytes, occult blood, mucus are the markers of antibiotic-associated diarrhea and can be used for its early diagnosis

Full Text Available Simona Ciccarelli,1 Ilaria Stolfi,1 Giuseppe Caramia2 1Neonatal Intensive Care Unit, Sapienza University of Rome, Rome, Italy; 2Division of Neonatology and Pediatrics, Maternal and Child Hospital "G. Salesi", Ancona, Italy Abstract: Acute gastroenteritis, characterized by the onset of diarrhea with or without vomiting, continues to be a major cause of morbidity and mortality in children in mostly resource-constrained nations. Although generally a mild and self-limiting disease, gastroenteritis is one of the most common causes of hospitalization and is associated with a substantial disease burden. Worldwide, up to 40% of children aged less than 5 years with diarrhea are hospitalized with rotavirus. Also, some microorganisms have been found predominantly in resource-constrained nations, including Shigella spp, Vibrio cholerae, and the protozoan infections. Prevention remains essential, and the rotavirus vaccines have demonstrated good safety and efficacy profiles in large clinical trials. Because dehydration is the major complication associated with gastroenteritis, appropriate fluid management (oral or intravenous is an effective and safe strategy for rehydration. Continuation of breastfeeding is strongly recommended. New treatments such as antiemetics (ondansetron, some antidiarrheal agents (racecadotril, and chemotherapeutic agents are often proposed, but not yet universally recommended. Probiotics, also known as “food supplement,” seem to improve intestinal microbial balance, reducing the duration and the severity of acute infectious diarrhea. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition and the European Society of Paediatric Infectious Diseases guidelines make a stronger recommendation for the use of probiotics for the management of acute gastroenteritis, particularly those with documented efficacy such as Lactobacillus rhamnosus GG, Lactobacillus reuteri, and Saccharomyces boulardii.

Aim of the study was to measure the effect of elastic and inelastic compression on calf muscle pump function in healthy male athletes. This was an experimental study which included 21 healthy male athletes. The ejection fraction (EF) of the venous calf pump was measured comparing the effects of a variety of compression materials: 1) sport compression stockings; 2) light zinc paste bandages; 3) sport compression stockings with additional Velcro® wraps over the calf. The influence of sport stocking and wraps on the venous calibre at the largest calf circumference in the lying and standing position was investigated using MRI. Inelastic compression exerting a median pressure in the standing position of 37.5 mmHg (zinc paste) and 48 mmHg (loosely applied straps over a sport stocking) achieved a significant increase of EF up to 100%. Sport stockings alone with a standing pressure of 19-24 mmHg did not show a significant change of EF. MRI demonstrated some venous narrowing in the lying but not in the standing position. By wrapping inelastic straps over the stocking an emptying of the veins in the lying and a considerable narrowing in the standing position could be observed. Venous calf pump function in athletes is not influenced by elastic sport stockings, but inelastic wraps either alone or applied over sport stockings lead to a significant enhancement.

The effect of embryonal thymic calf extracts (ETCE) on mice thymectomized at birth was investigated. ETCE was found to induce an increase in leukopenia and decrease in the level of serum gamma globulins; it also reduced survival time in mice. The effect of ETCE on lethally irradiated mice was also examined. Only long-term administration of ETCE prior to gamma irradiation at 750 rad prolonged the survival time of mice (40% permanent survival) as compared with irradiated controls; the leukocytes from mice retained mitotic capability. Neither long-term treatment with ETCE prior to irradiation at 1000 rad, nor short-term administration prior to 750 rad affected survival time. ETCE administered after irradiation of mice with 750 rad caused a rapid decrease in blood leukocytes and a significantly lowered survival time. (Auth.)

Full Text Available This study aims to investigate clinical and pathological findings of a clinical Coenurus cerebralis case in a 10-month-old Simmental male calf. Clinical examination of the calf revealed incoordination, irregular gait, failure to hold the head straight, leftward head tilt, and circling. The animal was diagnosed with C. cerebralis and euthanazia was recommended. The autopsy demonstrated a cyst (9x7 cm in the caudal of the left cerebral hemisphere within the cranium. The cyst caused compression over the ventral portion of the left cerebral hemisphere, while a marked perforation of 3-4 cm diameter was found on the sphenoid bone. Histopathologically, hyperemia and perivascular mononuclear cell infiltration were observed. In conclusion, we found it beneficial to present the clinical and pathological findings of this calf infected with C. cerebralis which is known to be a rare clinical entity among cattle.

The efficacy of Saccharomyces boulardii for treatment of childhood diarrhea remains unclear. Our objective was to systematically review data on the effect of S. boulardii on acute childhood diarrhea. Our data sources included Medline, Embase, CINAHL, Scopus, and The Cochrane Library up to September 2013 without language restrictions. Randomized controlled trials and non-randomized trials that evaluated effectiveness of S. boulardii for treatment of acute diarrhea in children were included. Two reviewers independently evaluated studies for eligibility and quality and extracted the data. In total, 1248 articles were identified, of which 22 met the inclusion criteria. Pooling data from trials showed that S. boulardii significantly reduced the duration of diarrhea (mean difference [MD], -19.7 hours; 95% confidence interval [CI], -26.05 to -13.34), stool frequency on day 2 (MD, -0.74; 95% CI, -1.38 to -0.10) and day 3 (MD, -1.24; 95% CI, -2.13 to -0.35), the risk for diarrhea on day 3 (risk ratio [RR], 0.41; 95% CI, 0.27 to 0.60) and day 4 (RR, 0.38; 95% CI, 0.24 to 0.59) after intervention compared with control. The studies included in this review were varied in the definition of diarrhea, the termination of diarrhea, inclusion and exclusion criteria, and their methodological quality. This review and meta-analysis show that S. boulardii is safe and has clear beneficial effects in children who have acute diarrhea. However, additional studies using head-to-head comparisons are needed to define the best dosage of S. boulardii for diarrhea with different causes.

Causes and correlates of calf mortality in captive Asian elephants (Elephas maximus.

Directory of Open Access Journals (Sweden)

Khyne U Mar

Full Text Available Juvenile mortality is a key factor influencing population growth rate in density-independent, predation-free, well-managed captive populations. Currently at least a quarter of all Asian elephants live in captivity, but both the wild and captive populations are unsustainable with the present fertility and calf mortality rates. Despite the need for detailed data on calf mortality to manage effectively populations and to minimize the need for capture from the wild, very little is known of the causes and correlates of calf mortality in Asian elephants. Here we use the world's largest multigenerational demographic dataset on a semi-captive population of Asian elephants compiled from timber camps in Myanmar to investigate the survival of calves (n = 1020 to age five born to captive-born mothers (n = 391 between 1960 and 1999. Mortality risk varied significantly across different ages and was higher for males at any age. Maternal reproductive history was associated with large differences in both stillbirth and liveborn mortality risk: first-time mothers had a higher risk of calf loss as did mothers producing another calf soon (<3.7 years after a previous birth, and when giving birth at older age. Stillbirth (4% and pre-weaning mortality (25.6% were considerably lower than those reported for zoo elephants and used in published population viability analyses. A large proportion of deaths were caused by accidents and lack of maternal milk/calf weakness which both might be partly preventable by supplementary feeding of mothers and calves and work reduction of high-risk mothers. Our results on Myanmar timber elephants with an extensive keeping system provide an important comparison to compromised survivorship reported in zoo elephants. They have implications for improving captive working elephant management systems in range countries and for refining population viability analyses with realistic parameter values in order to predict future population

Each year 48 pregnant, crossbred cows nursing steer calves (mean calving date = April 8) were assigned to a 2 x 2 x 2 factorial experiment replicated in three native range pastures. Treatment factors were: 1) no supplement (NS) or an individually fed supplement (S, 3 kg of a 34% protein supplement fed to cows every 3rd d); 2) calves weaned at the beginning (W, mid to late September) or at the end (NW, mid to late December) of the trial each year; or 3) calves sired by Hereford or Charolais bulls. Data were adjusted for cow size (initial hip height and initial and final weights and condition scores) by analyses of covariance using principal component coefficients as covariates. Change in cow weight and condition score were increased by S and W (P Forage intake was decreased (P intake (forage+supplement) was not affected by S but was decreased by W (P effects of treatments were observed the next spring in cow weight, condition score, and birth weight (NW decreased birth weight by 2 kg, P effects by the next fall on weaning weights or pregnancy rates. Milk yield decreased during the experimental period, and S maintained higher milk production in late lactation (P Calf ADG was increased by S and Charolais sires (P effects of feeding a 34% protein supplement to cows were to increase calf gains and improve persistency of lactation and efficiency; 2) delaying weaning decreased cow weight and condition score; 3) effects of weaning age and protein supplementation were highly dependent on forage and environmental conditions in any given year; and 4) whatever effects existed in a given year did not carry over to effects on next year's production as measured by pregnancy rates and weaning weights.

In order to compare intestinal morphology and function, diarrhea was produced in rats using laxatives in the diet. The 14 day study included two groups of rats with diarrhea (osmotic or secretory), two groups without diarrhea but with a degree of malnutrition which was similar to that seen in the rats with diarrhea (malnourished without diarrhea) and a well-nourished group (control). The inclusion of laxatives(lactose or bisoxatin acetate) cause a reduction in food intake, diarrhea an malnutrition. It also caused a reduction in dietary protein and fat digestibility which was proportional to the severity of diarrhea and more pronounced in secretory diarrhea. In the malnourished rats without diarrhea, malnutrition did not affect their absorptive function. Both in the rats with secretory and osmotic diarrhea an intestinal hypertrophy was observed. This hypertrophy was proportional to the severity of diarrhea and independent of its aetiology. In the intestines of the rats with both types of diarrhea there was inflammation, a greater number of mitotic figures but the flattening of the villi seen in the malnourished rats without diarrhea was not seen. In osmotic diarrhea there was, in addition, a patchy damage of the surface of the jejunal mucosa and an increment in the number of goblet cells, indicating a more severe intestinal deterioration. Since despite this greater deterioration, these rats absorbed more protein and fat we concluded that the alterations in intestinal morphology seen in this study was not predictive of intestinal function. The study also showed that diarrhea had a trophic effect on the intestine which did not occur in malnourished rats without diarrhea.

WHO guidelines recommend zinc supplementation as a key adjunct therapy for childhood diarrhea in developing countries, however zinc's anti-diarrheal effects remain only partially understood. Recently, it has been recognized that low-grade inflammation may influence stunting. In this study, we examined whether oral zinc supplementation could improve weight, intestinal inflammation, and diarrhea in undernourished weanling rats. Rats were undernourished using a northeastern Brazil regional diet (RBD) for two weeks, followed by oral gavage with a saturated lactose solution (30 g/kg) in the last 7 days to induce osmotic diarrhea. Animals were checked for diarrhea daily after lactose intake. Blood was drawn in order to measure serum zinc levels by atomic absorption spectroscopy. Rats were euthanized to harvest jejunal tissue for histology and cytokine profiles by ELISA. In a subset of animals, spleen samples were harvested under aseptic conditions to quantify bacterial translocation. Oral zinc supplementation increased serum zinc levels following lactose-induced osmotic diarrhea. In undernourished rats, zinc improved weight gain following osmotic diarrhea and significantly reduced diarrheal scores by the third day of lactose intake (p diarrhea and undernutrition and support the use of zinc to prevent the vicious cycle of malnutrition and diarrhea.

1977-10-01

Galantase, a preparation of lactose-decomposing enzyme, was used for 20 radiotherapeutic patients for prevention and treatment of diarrhea. The results were compared with those of 58 control cases without administration. In the 58 cases, the timing of onset of diarrhea during irradiation was examined, and the mechanism of onset of radioinjury in the digestive tract was discussed. Galantase 6 g/day was administered to 13 of the 20 patients simultaneously with institution of irradiation and to 7 patients simultaneously with the onset of diarrhea during irradiation. As radiotherapy, the patients were given remote cobalt irradiation 5 times a week, each consisting of 200 rad, a total dose of 5,000 rad, in a field of 14 - 16 x 14 - 16 cm by way of 2 ports (anterior and posterior). Diarrhea and soft stool both appeared by irradiation of less than 300 rad, and diarrhea was observed in 84%. Temporal diarrhea occurred in 3 of the 13 patients given galantase simultaneously with irradiation. Diarrhea continued for 6 days in one of the 6 cases in which galantase was administered simultaneously with the onset of diarrhea or watery stool. In the other 5, the stool recovered to be soft or normal 2-3 days after administration. Diarrhea during irradiaion appeared in 21.4% of the cases given galantase and 42.1% of those without it. The clinical value of galantase was recognized.

To design a maternal handwashing intervention for the newborn period, this qualitative study explored drivers of handwashing among mothers and other caregivers of neonates and infants in two rural areas of Bangladesh. We conducted 40 semi-structured observation sessions to observe handwashing behaviors of primiparous and multiparous mothers of neonates, and to understand the contextual factors that facilitated or hampered those behaviors. We then conducted 64 interviews with mothers of neonates and mothers of infants and 6 group discussions with mothers of infants, other female caregivers and fathers to explore perceptions, beliefs, and practices related to handwashing in the neonatal period. Based on a conceptual model and the Theory of Reasoned Action/Theory of Planned Behavior, we developed a conceptual model a priori, we performed thematic analysis to explain determinants of maternal handwashing behaviors. We conducted 200 h of observation among mothers of neonates. The age range of participating mothers varied between 17 and 25 years and their maximum education was up to 10th grade of schooling. Mothers, other female caregivers and fathers perceived a need to wash hands with or without soap before eating or before feeding a child by hand to prevent diarrhea. Mothers expressed the importance of washing their hands before holding a baby but were rarely observed doing so. All respondents prioritized using soap for visible dirt or feces; otherwise, water alone was considered sufficient. Lack of family support, social norms of infrequent handwashing, perceptions of frequent contact with water as a health threat and mothers' restricted movement during first 40 days of neonate's life, and childcare and household responsibilities adversely impacted handwashing behavior. Addressing emotive drivers of handwashing within existing social norms by engaging family members, ensuring handwashing facilities and clarifying neonatal health threats may improve maternal

Diarrhea and linear growth faltering continue to burden low-income countries and are among the most important contributors to poor health during early childhood. Diarrhea is thought to adversely affect linear growth, but catch-up growth can occur if no additional insults are experienced. We sought to characterize catch-up growth in relation to diarrhea burden in a multisite dataset of 1007 children. Using longitudinal anthropometry and diarrheal surveillance data from 7 cohort studies in 4 countries, we examined the relation between diarrhea prevalence and growth in 3- to 6-mo periods using linear mixed-effect models. Growth during each period was calculated as a function of age using linear splines. We incorporated the longitudinal prevalence of diarrhea in both current and previous periods into the model. Diarrhea during the current period was associated with slower linear and ponderal growth. Faster (catch-up) growth in length was observed in children with no diarrhea in age groups immediately after an age group in which diarrhea was experienced [age group >6–12 mo: 0.03 mm/mo for each percentage diarrhea prevalence in the previous period (95% CI: 0.007, 0.06) relative to 11.3 mm/mo mean growth rate; age group >12–18 mo: 0.04 mm/mo (95% CI: 0.02, 0.06) relative to 8.9 mm/mo mean growth rate; age group >18–24 mo: 0.04 mm/mo (95% CI: 0.003, 0.09) relative to 7.9 mm/mo mean growth rate]. The associations were stronger in boys than in girls when separate models were run. Similar results were observed when weight was the outcome variable. When diarrheal episodes are followed by diarrhea-free periods in the first 2 y of life, catch-up growth is observed that may allow children to regain their original trajectories. The finding of a greater effect of diarrhea on linear growth in boys than in girls was unexpected and requires additional study. Diarrhea burdens are high throughout the first 2 y of life in these study sites, therefore reducing the likelihood of

Intractable diarrhea in hyperthyroidism: management with beta-adrenergic blockade.

Bricker, L A; Such, F; Loehrke, M E; Kavanaugh, K

2001-01-01

To describe a patient with intractable diarrhea and thyrotoxic Graves' disease, for whom b-adrenergic blockade ultimately proved to be effective therapy for the diarrhea, and to review the types of hyperthyroidism-associated diarrhea. We present the clinical course of a young man with a prolonged siege of diarrhea that proved elusive to diagnostic inquiries and resistant to all means of management until its endocrine basis was discovered. Control of such cases with b-adrenergic blockade is discussed, as are the pathophysiologic bases of intestinal hypermotility in hyperthyroidism. A 26-year-old man with Down syndrome, and no prior gastrointestinal disorder, had insidious, chronic, constant diarrhea, which was associated with loss of 14 kg during a 5-month period. Numerous laboratory and imaging studies and endoscopic examinations failed to disclose the cause of the diarrhea. Furthermore, a broad range of antibiotics and other empiric remedies failed to control the problem. No other symptoms of hyperthyroidism were reported, but when the endocrinopathy was suspected and identified, the diarrhea was promptly controlled by treatment with propranolol. In patients with hyperthyroidism, two types of diarrheal disorders have been described-secretory diarrhea and steatorrhea; bile acid malabsorption may have a role in either of these settings. In addition to its capacity for blocking the peripheral effects of thyroid hormone on the heart and central nervous system, b-adrenergic blockade is effective in slowing intestinal transit time and ameliorating the uncommon diarrhea associated with hyperthyroidism. Thyroid hormone in excess, among its other possible effects on the gastrointestinal tract, may exert a stimulatory effect by means of intermediary sympathetic activation, as it does with the heart. Thus, sympathetic blockade can mimic the salutary effects on the gastrointestinal tract conventionally brought about by direct antithyroid therapy, and well before the

Several elk herds in the Greater Yellowstone Ecosystem are fed during winter to alleviate interactions with livestock, reduce damage to stored crops, and to manage for high elk numbers. The effects of supplemental feeding on ungulate population dynamics has rarely been examined, despite the fact that supplemental feeding is partially justified as necessary for maintaining or enhancing population growth rates. We used linear regression to assess how the presence of feedgrounds, snowpack, summer rainfall, indices of grizzly bear density and wolves per elk, elk population trend counts, brucellosis seroprevalence, and survey date were correlated with midwinter calf:cow ratios, a metric correlated with population growth, from 1983–2010 from 12 ecologically similar elk herd units (7 fed and 5 unfed) in Wyoming, USA. Our statistical approach allowed for rigorous tests of the hypotheses that supplemental feeding had positive effects on calf:cow ratios and reduced sensitivity of calf:cow ratios to bottom-up limitation relative to top-down limitation from native predators. Calf:cow ratios generally declined across all herd units over the study period and varied widely among units with feedgrounds. We found no evidence that the presence of feedgrounds had positive effects on midwinter calf:cow ratios in Wyoming. Further, fed elk showed stronger correlations with environmental factors, whereas calf:cow ratios for unfed elk showed stronger correlations with predator indices. Although we found no consistent association between winter feeding and higher calf:cow ratios, we did not assess late winter mortality and differences in human offtake between fed and unfed regions, which remain a priority for future research. 

Optimal control of diarrhea transmission in a flood evacuation zone

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

Data regarding hematologic reference intervals (RI) for neonatal calves have not been published yet. The aims of this study were: a) to establish hematology RIs for neonatal Holstein calves, b) to compare them with the RIs for lactating cows, and c) to investigate the relationship of age and gender with the hematologic profile of calves. Two-hundred and fifty-four clinically healthy Holstein calves (1-9days old, from 30 farms) and 82 healthy Holstein cows (between 30 and 150days in milk, from 10 farms) were blood sampled once for a complete blood count evaluation, using the ADVIA 120 hematology analyzer. An additional blood sample was collected from each calf for serum total protein concentration measurement. RIs and age-related RIs were calculated with the Reference Value Advisor freeware. Comparisons between calves and cows and between male and female calves were performed with t-test or Mann-Whitney test. Red blood cell count (RBC), white blood cell count (WBC), neutrophil, lymphocyte and platelet counts in calves were higher, while mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) were lower than in cows. Lymphocyte and platelets showed a notable increase through age. Finally, female calves had higher RBC, hematocrit and hemoglobin concentration than males. Age-specific RIs should be used for the interpretation of the complete blood count in Holstein calves. Copyright © 2018 Elsevier Ltd. All rights reserved.

Full Text Available Neonatal abstinence syndrome (NAS refers to the constellation of signs and symptoms exhibited by a newborn of drug-abusing mother. NAS is multisystemic disorder, most frequently involving central nervous and gastrointestinal systems with irritability, high-pitched cry, hyperactive reflexes, increased muscle tone, tremors, generalized convulsions, feeding and sleeping disorders, tachycardia, tachypnea, apnea, termolability and sweating, frequent hiccups, yawning and sneezing, vomiting, diarrhea and dehydration.Intrauterine narcotic disposition can give some other adverse effects beside NAS: fetal distress, premature birth, intrauterine growth retardation, microcephaly, increased incidence of congenital anomalies (cardiac and genitourinary anomalies, cleft palate, biliar atresia. Significantly increased risks of sudden infant’s death syndrome (SIDS, abnormalities in neurocognitive and behavioral development and deficiency in motor functions have also been noticed after the long-term surveys of these children.This paper is a case report of a newborn with developed clinical signs of NAS, but it also discusses diagnostics and management of such cases

Acute brief heat stress in late gestation alters neonatal calf innate immune functions.

Heat stress, as one of the environmental stressors affecting the dairy industry, compromises the cow milk production, immune function, and reproductive system. However, few studies have looked at how prenatal heat stress (HS) affects the offspring. The objective of this study was to evaluate the effect of HS during late gestation on calf immunity. Calves were born to cows exposed to evaporative cooling (CT) or HS (cyclic 23-35°C) for 1 wk at 3 wk before calving. Both bull and heifer calves (CT, n=10; HS, n=10) were housed in similar environmental temperatures after birth. Both CT and HS calves received 3.78 L of pooled colostrum within 12 h after birth and were fed the same diet throughout the study. In addition to tumor necrosis factor α, IL-1β, IL-1 receptor antagonist (IL-1RA), and toll-like receptor (TLR)2, and TLR4 mRNA expression, the expression of CD14(+) and CD18(+) cells, and DEC205(+) dendritic cells were determined in whole blood samples at d 0, 3, 7, 14, 21, and 28. The neutrophil to lymphocyte ratio, differential cell counts, and the hematocrit were also determined. During late gestation, the HS cows had greater respiration rates, rectal temperatures, and tended to spend more time standing compared with the CT cows. The HS calves had less expression of tumor necrosis factor-α and TLR2 and greater levels of IL-1β, IL-1RA, and TLR4 compared with CT calves. The HS calves also had a greater percentage of CD18(+) cells compared with the CT calves. Additionally, a greater percentage of neutrophils and lesser percentage of lymphocytes were in the HS calves compared with the CT calves. The results indicate that biomarkers of calves' immunity are affected in the first several weeks after birth by HS in the dam during late gestation.

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

Integrating scientific knowledge into large-scale restoration programs: the CALFED Bay-Delta Program experience

Science.gov (United States)

Taylor, K.A.; Short, A.

2009-01-01

Integrating science into resource management activities is a goal of the CALFED Bay-Delta Program, a multi-agency effort to address water supply reliability, ecological condition, drinking water quality, and levees in the Sacramento-San Joaquin Delta of northern California. Under CALFED, many different strategies were used to integrate science, including interaction between the research and management communities, public dialogues about scientific work, and peer review. This paper explores ways science was (and was not) integrated into CALFED's management actions and decision systems through three narratives describing different patterns of scientific integration and application in CALFED. Though a collaborative process and certain organizational conditions may be necessary for developing new understandings of the system of interest, we find that those factors are not sufficient for translating that knowledge into management actions and decision systems. We suggest that the application of knowledge may be facilitated or hindered by (1) differences in the objectives, approaches, and cultures of scientists operating in the research community and those operating in the management community and (2) other factors external to the collaborative process and organization.

Duodenal ileus caused by a calf feeding nipple in a cow

Gerspach Christian

2011-01-01

Full Text Available Abstract Background The aim of this report was to describe duodenal obstruction caused by a rubber foreign body in a cow. Case Presentation The clinical, biochemical and ultrasonographic findings in a five-year-old Swiss Braunvieh cow with duodenal ileus caused by a calf feeding nipple are described. The main clinical signs were anorexia, ruminal tympany, decreased faecal output and abomasal reflux syndrome. Ultrasonographic examination revealed reticular hyperactivity and a dilated duodenum. A diagnosis of duodenal ileus was made and the cow underwent right-flank laparotomy, which revealed a dilation of the cranial part of the duodenum because of obstruction by a pliable foreign body. This was identified via enterotomy as a calf feeding nipple. The cow was healthy at the time of discharge four days after surgery and went on to complete a successful lactation. Conclusions To our knowledge, this is the first description of duodenal obstruction by a calf feeding nipple. This is an interesting case, which broadens the spectrum of the causes of duodenal ileus, which is usually caused by obstruction of the duodenum by a phytobezoar.

Hospital-based studies to determine the etiology of deaths from diarrhea are scarce. In this study, we specifically analyzed deaths due to rotavirus to assess the rotavirus impact on diarrhea mortality. To determine the rotavirus proportion contributing to mortality due to diarrhea, we analyzed data obtained from a hospital-based mortality surveillance, conducted over 7 years, in the Ciudad Hospitalaria Dr. Enrique Tejera, Valencia, Venezuela. Rotavirus was identified in stool samples collected from children who died of diarrhea, by a confirmatory ELISA and/or reverse transcription polymerase chain reaction. Our results show that rotavirus (21%; 21/100) is the leading cause of death due to diarrhea among children causes in this age group. Shigella spp. (19%; 13/69) was the second most important cause of death, followed by calicivirus (6%; 3/53). Furthermore, this study documents a seasonal pattern in the deaths due to rotavirus (odds ratio 3.28; 95% confidence interval 1.13-9.76). For Venezuela, it is estimated that approximately 300 children cause of death due to diarrhea, which supports previous estimations. This is the first study to present data of cause-specific mortality due to diarrhea based on hospital surveillance of diarrhea etiologies.

Mean serum concentrations of FMOX at 30 minutes after administration were 24.3 micrograms/ml, 47.6 micrograms/ml, and 85.8 micrograms/ml at doses of 10 mg/kg, 20 mg/kg, and 40 mg/kg administered, respectively. 2. Mean serum half-lives of FMOX were 3.4 hours in 0-3 day-old neonates, and 2.6 hours in 4 day-old or older subjects. 3. A dose response was evident among different dose groups given 10 mg/kg, 20 mg/kg, and 40 mg/kg. 4. Urinary recovery rates of FMOX in the first 6 hours after administration ranged between 12.8 and 51.1%. 5. FMOX was effective in 7 out of 8 cases in which causative pathogens were identified. 6. Diarrhea was observed in 1 case as a side effect of the drug, but the symptom was relieved soon after the completion of the treatment. There was no case in which any abnormal laboratory results were observed. 7. FMOX has a broad spectrum of activities against Gram-positive and Gram-negative aerobes and anaerobes. It is stable against most of beta-lactamases. It was demonstrated to be highly effective in our study, and yet without any serious side effects. FMOX is therefore considered to be one of the useful agents of the first choice for the treatment of bacterial infections such as sepsis and urinary tract infections in neonates and infants.

Although the osmotic gap of fecal fluid is often used to distinguish osmotic diarrhea from secretory diarrhea, there has never been a scientific evaluation of the validity of this concept. Similarly, although a low fecal fluid pH value is used to indicate that diarrhea is mediated by carbohydrate malabsorption, the validity of this method is unproven. Therefore, in the present study, diarrhea was induced in normal subjects by different mechanisms and fecal fluid osmotic gap (using an assumed fecal fluid osmolality of 290 mOsm/kg) and pH were measured. In secretory diarrhea caused by phenolphthalein, the osmotic gap was always less than 50 mOsm/kg, whereas in osmotic diarrhea caused by polyethylene glycol, magnesium hydroxide, lactulose, and sorbitol, the osmotic gap always exceeded 50 mOsm/kg. In osmotic diarrhea caused by sodium sulfate, the fecal fluid osmotic gap was less than 50 mOsm/kg, but phenolphthalein-induced secretory diarrhea could be distinguished from sodium sulfate-induced osmotic diarrhea by the fecal chloride concentration. When diarrhea was caused by carbohydrate malabsorption (lactulose or sorbitol), the fecal fluid pH was always less than 5.6 and usually less than 5.3; by contrast, other causes of diarrhea rarely caused a fecal pH as low as 5.6 and never caused a pH less than 5.3. It is concluded that measurement of fecal fluid osmotic gap and pH can distinguish various mechanisms of experimental diarrhea in normal subjects. The concepts on which these tests are based are therefore verified experimentally.

Diseases of the human gastrointestinal (GI) tract are often accompanied by diarrhea with profound alterations in the GI microbiota termed dysbiosis. Whether dysbiosis is due to the disease itself or to the accompanying diarrhea remains elusive. With this study we characterized the net effects of osmotic diarrhea on the composition of the GI microbiota in the absence of disease. We induced osmotic diarrhea in four healthy adults by oral administration of polyethylene glycol 4000 (PEG). Stool as well as mucosa specimens were collected before, during and after diarrhea and 16S rDNA-based microbial community profiling was used to assess the microbial community structure. Stool and mucosal microbiotas were strikingly different, with Firmicutes dominating the mucosa and Bacteroidetes the stools. Osmotic diarrhea decreased phylotype richness and showed a strong tendency to equalize the otherwise individualized microbiotas on the mucosa. Moreover, diarrhea led to significant relative shifts in the phyla Bacteroidetes and Firmicutes and to a relative increase in the abundance of Proteobacteria on the mucosa, a phenomenon also noted in several inflammatory and diarrheal GI diseases. Changes in microbial community structure induced by osmotic diarrhea are profound and show similarities to changes observed in other GI diseases including IBD. These effects so must be considered when specimens from diarrheal diseases (i.e. obtained by stratification of samples according to diarrheal status) or conditions wherein bowel preparations like PEG (i.e. specimens obtained during endoscopy) are used.

To evaluate the association between calf circumference and gait speed in elderly patients 65 years or older at Geriatric day clinic at Peruvian Centro Médico Naval. Cross-sectional, retrospective study. We assessed 139 participants, 65 years or older at Peruvian Centro Médico Naval including calf circumference, gait speed and Short Physical Performance Battery. With bivariate analyses and logistic regression model we search for association between variables. The age mean was 79.37 years old (SD: 8.71). 59.71% were male, the 30.97% had a slow walking speed and the mean calf circumference was 33.42cm (SD: 5.61). After a bivariate analysis, we found a calf circumference mean of 30.35cm (SD: 3.74) in the slow speed group and, in normal gait group, a mean of 33.51cm (SD: 3.26) with significantly differences. We used logistic regression to analyze association with slow gait speed, founding statistically significant results adjusting model by disability and age. Low calf circumference is associated with slow speed walk in population over 65 years old. Copyright © 2014. Published by Elsevier Espana.

The Effect of Calf Gender on Milk Production in Seasonal Calving Cows and Its Impact on Genetic Evaluations.

Directory of Open Access Journals (Sweden)

Melanie K Hess

Full Text Available Gender of the calf whose birth initiates lactation could influence whole lactation milk yield of the dam due to hormonal influences on mammary gland development, or through calf gender effects on gestation length. Fetal gender could influence late lactation yields because cows become pregnant at peak lactation. The effects of calf gender sequences in parities 1-3 were assessed by separately fitting animal models to datasets from New Zealand comprising 274 000 Holstein Friesian and 85 000 Jersey cows, decreasing to 12 000 and 4 000 cows by parity 3. The lactation initiated by the birth of a female rather than a male calf was associated with a 0.33-1.1% (p≤0.05 higher milk yield. Female calf gender had carryover effects associated with higher milk yield in second lactations for Holstein Friesians (0.24%; p = 0.01 and third lactations for Jerseys (1.1%; p = 0.01. Cows giving birth to bull calves have 2 day longer gestations, which reduces lactation length in seasonal calving herds. Adding a covariate for lactation length to the animal model eroded some of these calf gender effects, such that calving a female led to higher milk yield only for second lactation Holstein Friesians (1.6%; p = 0.002. The interval centering method generates lower estimates of whole lactation yield when Wood's lactation curves are shifted to the right by 2 days for male calves and this explained the higher yield in female calves when differences in lactation length were considered. Correlations of estimated breeding values between models including or excluding calf gender sequence were 1.00 for bulls or cows. Calf gender primarily influences milk yield through increased gestation length of male calves, and bias associated with the interval centering method used to estimate whole lactation milk yields. Including information on calf gender is unlikely to have an effect on selection response in New Zealand dairy cattle.

The association between a number of individual animal and herd level factors and calving problems in beef cows and heifers were examined. Data were from the 1987 calving season for a subset of 123 herds which maintained individual-animal records, from a sample of 180 randomly selected Ontario cow-calf herds. The median herd dystocia rate was 5.8% and 24.4% of herds had no dystocias. The median herd stillbirth rate was 2.8%, and 33.3% of herds had no stillbirths. Dystocias and stillbirths were much more common in heifers than in cows. Separate statistical models of dystocia and stillbirth for cows and heifers were created. Dystocia in cows was associated with calf sex, previous calving assistance and large breed type and birth weight. Variations in 1987 cow herd dystocia rates were associated with calving season, location and density, and the herd dystocia rate in 1986. Dystocia in heifers was associated with large breed type and calf birth weight. Herd-level management practices associated with increased heifer dystocia rates included breeding heifers to calve earlier than cows and rearing heifers together with the cow herd. Stillbirths for both cows and heifers were associated with calving assistance, particularly hard assistance. Herd-level management and other factors were unassociated with stillbirths. PMID:1586893

Intermittent pneumatic compression of the calf and/or thigh effectively decreases the incidence of deep venous thrombosis and other thrombotic sequelae but clinical data comparing these modalities are currently lacking. A total of 90 patients undergoing major urological surgery was randomly assigned to receive calf length or thigh length pneumatic compression for antithrombotic prophylaxis. Duplex ultrasound of the lower extremities was performed preoperatively and twice postoperatively to evaluate for deep venous thrombosis. Health care providers in the operating room, recovery room and ward were asked to compare the compression systems, and a cost analysis was performed. A total of 47 patients wore the thigh length sequential pneumatic sleeves and 43 wore calf length uniform compression systems. A pulmonary embolus without evidence of deep venous thrombosis was detected in 1 patient (2%) using the thigh length system. A thrombus was detected in the common femoral vein by duplex ultrasonography in 1 patient (2%) with the calf length system. Nursing personnel found the calf length sleeves easier to apply and more comfortable by patient account but they were satisfied with both systems. There was a significant cost savings with the calf length pneumatic compression system. Calf and thigh length pneumatic compression systems similarly decrease the risk of deep venous thrombosis in patients undergoing urological surgery. The calf length system has the added advantage of being less expensive and easier to use.

Full Text Available Abstract Background Diarrhea is a major public health problem in Thailand. The Ministry of Public Health, Thailand, has been trying to monitor and control this disease for many years. The methodology and the results from this study could be useful for public health officers to develop a system to monitor and prevent diarrhea outbreaks. Methods The objective of this study was to analyse the epidemic outbreak patterns of diarrhea in Chiang Mai province, Northern Thailand, in terms of their geographical distributions and hotspot identification. The data of patients with diarrhea at village level and the 2001–2006 population censuses were collected to achieve the objective. Spatial analysis, using geographic information systems (GIS and other methods, was used to uncover the hidden phenomena from the data. In the data analysis section, spatial statistics such as quadrant analysis (QA, nearest neighbour analysis (NNA, and spatial autocorrelation analysis (SAA, were used to identify the spatial patterns of diarrhea in Chiang Mai province. In addition, local indicators of spatial association (LISA and kernel density (KD estimation were used to detect diarrhea hotspots using data at village level. Results The hotspot maps produced by the LISA and KD techniques showed spatial trend patterns of diarrhea diffusion. Villages in the middle and northern regions revealed higher incidences. Also, the spatial patterns of diarrhea during the years 2001 and 2006 were found to represent spatially clustered patterns, both at global and local scales. Conclusion Spatial analysis methods in GIS revealed the spatial patterns and hotspots of diarrhea in Chiang Mai province from the year 2001 to 2006. To implement specific and geographically appropriate public health risk-reduction programs, the use of such spatial analysis tools may become an integral component in the epidemiologic description, analysis, and risk assessment of diarrhea.

Complex Vertebral Malformation, a congenital and lethal genetic defect of Holstein breed, has been recently observed in different Countries all over the world. In this paper the AA describe the clinical and radiological aspects of CVM in a two day old female calf. The disease was characterized by low body weight, symmetrical arthrogryposis and partial rotation of all legs and scoliosis. Calf was alert and showed physiological appetite, but was not able to maintain the quadrupedal stance. Radiographs of the vertebral column showed multiple vertebral anomalies, including hemivertebrae, fused and misshapen vertebrae and ribs and scoliosis, that affected mainly the caudal, cervical and thoracic regions. At necropsy, besides the skeleton anomalies, complex malformation of the heart was observed, which included atrial and interventricular defects and patent ductus arteriosus. This is the first case of CVM completely documented and genetically tested in Italy [it

Clostridium perfringens causes diarrhea in neonatal piglets, thereby affecting commercial swine farming. The objective of this study was to determine the prevalence and characterize antimicrobial resistance in C. perfringens isolated from diarrheal neonatal piglets in Thailand. A total of 260 rectal swab samples were collected from 13 farms and were subjected to C. perfringens isolation. A total of 148 samples were PCR-positive for C. perfringens toxin genes, from which 122 were recovered. All isolates were cpb2-encoding C. perfringens type A and enterotoxin gene negative. Most of the isolates were susceptible to ampicillin, bacitracin, chlorotetracycline, doxycycline, and oxytetracycline with MIC50 values ranging from 0.32 to 8 μg/ml. The high resistance rates were observed for ceftiofur, enrofloxacin, erythromycin, lincomycin, and tylosin. Among resistant isolates, 82% were resistant to more than one type of antibiotics. The distinct pattern of multiple drug resistance in C. perfringens was observed in different regions, potentially reflecting the farm specific usage of these agents. Copyright © 2016 Elsevier Ltd.

Probiotics in antibiotic associated diarrhea in children

Directory of Open Access Journals (Sweden)

Matjaž Homan

2013-10-01

Full Text Available The use of antibiotics that disturb the gastrointestinal microbiota is associated with diarrhea, which occurs in up to half of treated children. Symptoms are usually mild and children do not need hospitalization. Probiotics are live microorganisms, which restore intestinal microbiota during antibiotic therapy through different mechanisms such as stimulation of immunity, secretion of anti-inflammatory factors, and production of antimicrobial substances. The use of different strains of probiotics in antibiotic-associated diarrhea was evaluated in several studies in adults but less frequently in pediatric population. They also confirmed the value of probiotics in the prevention of antibiotic-associated diarrhea in children, particularly Lactobacillus strain GG and Saccharomyces boulardii. The use of probiotics in childhood is safe. A proper strain must be introduced at the beginning of antibiotic treatment in a sufficient concentration.

Chronic unexplained diarrhea: what to do when the initial workup is negative?

Science.gov (United States)

Talley, Nicholas J

2008-01-01

Diagnosing the patient with chronic diarrhea can still be a major challenge despite modern testing. It is useful initially to consider what may be the likely underlying pathophysiologic explanation for diarrhea from the history (osmotic, secretory, inflammatory, or motility related) and let this information drive the management algorithm. However, gastroenterologists frequently ask how far the workup should go and when a confident diagnosis of functional diarrhea can be made. In contrast to diarrhea-predominant irritable bowel syndrome, the evidence that functional diarrhea exists as a real diagnostic entity is actually remarkably unconvincing.

This research was designed to examine genotype x environment interactions in cow-calf growth performance of grazing animals. Angus and Brangus cow-calf pairs (minimum of six per breed) were allowed to rotationally graze (14-d intervals) treatment pastures from approximately May through early October in each of 2 yr. Treatment pastures contained relatively pure stands of Alicia bermudagrass (AP) or a mixed stand of common bermudagrass and dallisgrass (CDP). Forage allowance was equalized, using "put-and-take" cow-calf pairs, among forage and breed types at the initiation of each 14-d grazing interval. Forage samples were obtained in each paddock at the initiation of each grazing interval. Forage CP concentration was greater (P < .05; 13.5 vs 11.6%) and NDF concentration was less (P < .05; 63.8 vs 70.6%) for CDP than for AP. Daily weight loss was similar for Angus and Brangus cows, but it was greater (P < .05) for cows grazing AP than for cows grazing CDP. Calf ADG during the grazing season was 35% greater (P < .05) for CDP than for AP pastures and was 23% greater (P < .01) for Brangus than for Angus calves. Relative performance of Angus and Brangus cow-calf pairs was consistent between forages; no breed x forage interactions were observed.

The temporal sensitivity of the surveillance system (TemSSe) for Bovine Viral Diarrhea (BVD) in Danish dairy herds was evaluated. Currently, the Danish antibody blocking ELISA is used to test quarterly bulk tank milk (BTM). To optimize the surveillance system as an early warning system, we considered the possibility of using the SVANOVIR ELISA, as this test has been shown to detect BVD-positive herds earlier than the blocking ELISA in BTM tests. Information from data (2010) and outputs from two published stochastic models were fed into a stochastic scenario tree to estimate the TemSSe. For that purpose we considered: the risk of BVD introduction into the dairy population, the ELISA used and the high risk period (HRP) from BVD introduction to testing (at 90 or 365 days). The effect of introducing one persistently infected (PI) calf or one transiently infected (TI) milking cow into 1 (or 8) dairy herd(s) was investigated. Additionally we estimated the confidence in low (PLow) herd prevalence (tree methodology, could be applied to optimize early warning surveillance systems of different animal diseases.

Two 60-d experiments were conducted to evaluate the effects of supplementing degradable (DIP) and(or) undegradable (UIP) intake protein on the performance of lactating first-calf heifers. Diets were formulated to meet the requirements for either DIP, metabolizable protein (MP), or both when diets contained low-quality grass hay and an efficiency of microbial protein synthesis estimate of 10%. In Exp. 1, 32 individually fed first-calf heifers (avg 395 kg) were allotted to a 2 x 2 factorial arrangement of treatments (main effects of DIP, MP, and DIP x MP interaction) 1 d after calving. Cows consumed a basal diet of chopped crested wheat grass hay (4.3% CP, 67% DIP) ad libitum. Supplemental DIP and UIP were supplied by varying the ratios of soybean meal (75% DIP) and a heat-treated, protected soybean meal (70% UIP). Cow weight gain was better (P calf weight gain was not increased by supplementing the cow with DIP. Supplemental UIP did not (P > 0.40) improve cow or calf weight gain. Blood urea N levels were higher (P milk production estimates were similar among treatments, as were digestibilities of OM and ADF. Nitrogen digestibility was greater when supplemental DIP was fed, but providing additional UIP did not (P = 0.15) change N digestibilities. Experiment 2 evaluated similar supplements using the same experimental design to determine changes in cow and calf weight gain, body condition score, and pregnancy rate. Seventy-two first-calf heifers (avg 441 kg) were allotted to supplement treatments 1 d after calving and were fed grass hay (5% CP, 53% DIP, 10% microbial efficiency) for ad libitum consumption for 60 d. Supplements were individually fed three times/week. Varying the ratios of soybean meal, heat-treated soybean meal, and corn gluten meal provided additional DIP and UIP. Unlike in Exp. 1, supplemental UIP improved (P calf gains. Data suggest that the efficiency of microbial protein synthesis for this forage-based diet was probably less than 10%.

Post-infectious sequelae of travelers' diarrhea.

Science.gov (United States)

Connor, Bradley A; Riddle, Mark S

2013-01-01

Travelers' diarrhea (TD) has generally been considered a self-limited disorder which resolves more quickly with expeditious and appropriate antibiotic therapy given bacteria are the most frequently identified cause. However, epidemiological, clinical, and basic science evidence identifying a number of chronic health conditions related to these infections has recently emerged which challenges this current paradigm. These include serious and potentially disabling enteric and extra-intestinal long-term complications. Among these are rheumatologic, neurologic, gastrointestinal, renal, and endocrine disorders. This review aims to examine and summarize the current literature pertaining to three of these post-infectious disorders: reactive arthritis, Guillain-Barré syndrome, and post-infectious irritable bowel syndrome and the relationship of these conditions to diarrhea associated with travel as well as to diarrhea associated with gastroenteritis which may not be specifically travel related but relevant by shared microbial pathogens. It is hoped this review will allow clinicians who see travelers to be aware of these post-infectious sequelae thus adding to our body of knowledge in travel medicine. Data for this article were identified by searches of PubMed and MEDLINE, and references from relevant articles using search terms "travelers' diarrhea" "reactive arthritis" "Guillain-Barré syndrome" "Post-Infectious Irritable Bowel Syndrome." Abstracts were included when related to previously published work. A review of the published literature reveals that potential consequences of travelers' diarrhea may extend beyond the acute illness and these post-infectious complications may be more common than currently recognized. In addition since TD is such a common occurrence it would be helpful to be able to identify those who might be at greater risk of post-infectious sequelae in order to target more aggressive prophylactic or therapeutic approaches to such individuals.

Investigations were made on the following points which were possible factors in the appearance of diarrhea during irradiation of the whole pelvis for uterine cancer: (a) daily dose of 200 and 180 rads, (b) age, (c) radical operation for uterine cancer, (d) previous history of abdominal operation, (e) disease stage of II or III, and (f) grade of infiltration of the rectum with cancer cells. Results thereby obtained are summarized as follows: 1) A significant difference between the dose of 200 and 180 rads in causing diarrhea was found only in patients receiving radiation therapy alone, without a previous history of abdominal operation. 2) Patients who underwent a radical operation for uterine cancer showed a significantly higher incidence of diarrhea than those without such an operation. 3) The age of patients, previous history of abdominal operation, and grade of infiltration of cancer cells into the rectum had almost no effect on the incidence of diarrhea. 4) There was no significant difference in the frequency of diarrhea between stage II and III, although the higher incidence recorded for the latter group was between a 10 and 20% level of significance.

Rotavirus were detected in 47.8% analyzed samples (87/184, G and P-genotype of rotavirus were G[1] (37.5% and P[6] (53.5%. Most subjects were males (56%, 6–11 months of age (35%. Most common clinical manifestations besides diarrhea were dehydration (72.7% and vomiting (50%. Subjects with positive rotavirus more common had dehydration (72% vs 28% and vomiting (61% vs 39%. In conclusion, vomiting and dehydration are the prominent clinical manifestations of diarrhea with positive rotavirus infection. G1 and P6 are the most common genotype of rotavirus.

Daily food histories for one month were obtained in summer, 1975, from students attending a Mexican university to determine the influence of food consumption on the development and etiology of diarrhea. In newly-arrived students from the U.S. who ate half or more of their meals in the school cafeteria and public restaurants there were significant increases in diarrhea (p less than 0.005); shigella infection (p less than 0.05) and toxigenic E. coli infection (p less than 0.025) compared to the students eating a comparable number of meals in private homes. In the summer U.S. students there was also an association of diarrhea and eating from street vendors (p less than 0.05). In full-time U.S. students who had lived in Mexico a year or longer as well as in Latin American students a relationship between location of meals and occurrence of enteric disease was not apparent. High numbers of enteric bacteria were recovered from food from the school's cafeteria, public restaurants, street vendors and small grocery stores. Shigella were isolated from cooked and uncooked hamburger patties from the school cafeteria. Four shigella carriers were found among kitchen personnel at the school. This study demonstrates that food serves as a major vehicle through which travelers' diarrhea occurs.

An international, quasi-experimental, clinical trial of 'before-and-after type' was conducted to find out the role of octreotide in chemo and radiotherapy-induced diarrhea on thirty patients. Among these 19 patients had advanced cancer and 11 with acute leukemia. All patients were given IV fluids and Loperamide for 5 days. The patients who did not respond during this period were administered with octreotide subcutaneously for another 5 days and response against diarrhea was noted. We found that only 10% patients responded to loperamide therapy whereas in the remaining 90% patients an excellent response was noted as 96.29% of these patients responded to octreotide therapy which stopped their diarrhea (P<0.005) leading us to the conclusion that, octreotide is a safe and effective drug in the management of chemo and radiotherapy-induced diarrhea.

The objective of this research was to assess the association between 4 cow reproductive and weight traits, and 2 preweaning calf traits and ELISA scores for paratuberculosis (0 = negative, 1 = suspect, 2 = weak-positive, and 3 = positive) in a multibreed herd of cows ranging from 100% Angus (A) to 100% Brahman (B). Cow data were 624 gestation lengths (GL), 358 records of time open (TO), 605 calving intervals (CI), and 1240 weight changes from November to weaning in September (WC) from 502 purebred and crossbred cows. Calf data consisted of 956 birth weights (BWT), and 923 weaning weights adjusted to 205 d of age (WW205) from 956 purebred and crossbred calves. Traits were analyzed individually using multibreed mixed models that assumed homogeneity of variances across breed groups. Covariances among random effects were assumed to be zero. Fixed effects were year, age of cow, sex of calf, year x age of cow interaction (except WC), age of cow x sex of calf interaction (only for WC), and covariates for B fraction of sire and cow, heterosis of cow and calf, and ELISA score. Random effects were sire (except for TO and CI), dam, and residual. Regression estimates of cow and calf traits on ELISA scores indicated that lower cow fertility (longer TO), lower ability of cows to maintain weight (negative WC), lower calf BWT, and lower calf WW205 were associated with higher cow ELISA scores. Further research on the effects of subclinical paratuberculosis in beef cattle at regional and national levels seems advisable considering the large potential economic cost of this disease.

Chronic diarrhea. Diagnosis and clinical evaluation

Pineda O, Luis F; Otero R, William; Arbelaez M, Victor

2004-01-01

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

A calf persistently infected with Hobi-like pestivirus displayed severe clinical signs and subsequently died. Gross lesions and histopathological changes were suggestive of hemorrhagic and necrotic inflammation involving several tissues. A Hobi-like pestivirus pair was isolated from the dead calf, i.e., cytopathogenic (CP) and noncytopathogenic (NCP) strains strictly related to each other and to Italian prototype isolates at the genetic level. Two biotype-specific real-time reverse transcription-PCR assays determined the time of the emergence of the CP virus as 1 month before the calf's death. This highest RNA titers were reached in lymphoid and nervous system tissues, whereas only traces of CP viral RNA were found in blood. In contrast, great NCP virus loads were present in all tissues and biological fluids. The present report provides new insights into the pathogenesis and molecular mechanisms of this emerging group of pestiviruses. Copyright © 2014, American Society for Microbiology.

Trehalose is widely used for cryopreservation of various cells and tissues. Until now, the effect of trehalose supplementation on cell viability and antioxidant enzyme activity in frozen-thawed bovine calf testicular tissue remains unexplored. The objective of the present study was to compare the effect of varying doses of trehalose in cryomedia on cell viability and key antioxidant enzymes activities in frozen-thawed bovine calf testicular tissue. Bovine calf testicular tissue samples were collected and cryopreserved in the cryomedias containing varying doses (0, 5, 10, 15, 20 and 25%; v/v) of trehalose, respectively. Cell viability, total antioxidant capacity (T-AOC) activity, catalase (CAT) activity, superoxide dismutase (SOD) activity, glutathione (GSH) content and malondialdehyde (MDA) content were measured and analyzed. The results showed that cell viability, T-AOC activity, SOD activity, CAT activity and GSH content of frozen-thawed bovine calf testicular tissue was decreased compared with that of fresh group (Pcell viability and antioxidant enzyme activity (SOD and CAT) among frozen-thawed groups (P0.05). In conclusion, the cryomedia added 15% trehalose reduced the oxidative stress and improved the cryoprotective effect of bovine calf testicular tissue. Further studies are required to obtain more concrete results on the determination of antioxidant capacity of trehalose in frozen-thawed bovine calf testicular tissue. Copyright © 2015 Elsevier Inc.

Diarrhea in a Border Terrier was associated with inflammatory lesions of the myenteric plexus. This lesion has been documented rarely in dogs. It is speculated that the myenteric plexus lesions were responsible for an autonomic nervous system dysfunction, which resulted in extreme intestinal hypermotility and subsequent diarrhea. Suggested tests for dogs suspected to have autonomic dysfunction are given

Rotaviruses infect mature, differentiated enterocytes of the small intestine and, by an unknown mechanism, escape the gastrointestinal tract and cause viremia. The neonatal rat model of rotavirus infection was used to determine the kinetics of viremia, spread, and pathology of rotavirus in extraintestinal organs. Five-day-old rat pups were inoculated intragastrically with an animal (RRV) or human (HAL1166) rotavirus or phosphate-buffered saline. Blood was collected from a subset of rat pups, and following perfusion to remove residual blood, organs were removed and homogenized to analyze rotavirus-specific antigen by enzyme-linked immunosorbent assay and infectious rotavirus by fluorescent focus assay or fixed in formalin for histology and immunohistochemistry. Viremia was detected following rotavirus infection with RRV and HAL1166. The RRV 50% antigenemia dose was 1.8 × 103 PFU, and the 50% diarrhea dose was 7.7 × 105 PFU, indicating that infection and viremia occurred in the absence of diarrhea and that detecting rotavirus antigen in the blood was a more sensitive measure of infection than diarrhea. Rotavirus antigens and infectious virus were detected in multiple organs (stomach, intestines, liver, lungs, spleen, kidneys, pancreas, thymus, and bladder). Histopathological changes due to rotavirus infection included acute inflammation of the portal tract and bile duct, microsteatosis, necrosis, and inflammatory cell infiltrates in the parenchymas of the liver and lungs. Colocalization of structural and nonstructural proteins with histopathology in the liver and lungs indicated that the histological changes observed were due to rotavirus infection and replication. Replicating rotavirus was also detected in macrophages in the lungs and blood vessels, indicating a possible mechanism of rotavirus dissemination. Extraintestinal infectious rotavirus, but not diarrhea, was observed in the presence of passively or actively acquired rotavirus-specific antibody. These

Salta city is the capital of the province with the same name located in the northwest of Argentina. Its great growth over the last decade was not organized and the population expanded to occupy places where water and sanitation were not yet available. Although the Arenales River, crossing the city, receives the impact of point and non-point source pollution, the water is used for many purposes, including domestic in the poorest areas, industrial, and recreational with children as the main users. According to the World Health Organization, an estimated 24% of the global disease burden and 23% of all deaths can be attributed to environmental factors. In particular, an estimated 94% of the diarrheal burden of disease is attributable to environment, and is associated with risk factors such as unsafe drinking water and poor sanitation and hygiene. Chronic diarrhea can be caused by an infection or other etiologies; however, most of the times the etiological agent is not identified. All the cases of diarrhea and parasitosis reported during 2005 in four public health centers of the city of Salta were classified by gender and age, analyzed, and represented geographically to show areas of higher morbidity rates, which were probably related to environmental factors. Water, poor sanitation, and pollution are candidate risk factors. Diarrhea cases showed seasonality, with the highest incidence during late spring and summer, while parasitosis was persistent throughout the year. Our spatial analysis permitted us to detect the regions of higher incidence of diarrhea and parasitosis during 2005 in the area of study.

Association of Atypical Enteropathogenic Escherichia coli with Diarrhea and Related Mortality in Kittens.

Diarrhea is responsible for the death of approximately 900,000 children per year worldwide. In children, typical enteropathogenic Escherichia coli (EPEC) is a common cause of diarrhea and is associated with a higher hazard of death. Typical EPEC infection is rare in animals and poorly reproduced in experimental animal models. In contrast, atypical EPEC (aEPEC) infection is common in both children and animals, but its role in diarrhea is uncertain. Mortality in kittens is often attributed to diarrhea, and we previously identified enteroadherent EPEC in the intestines of deceased kittens. The purpose of this study was to determine the prevalence and type of EPEC in kittens and whether infection was associated with diarrhea, diarrhea-related mortality, gastrointestinal pathology, or other risk factors. Kittens with and without diarrhea were obtained from two shelter facilities and determined to shed atypical EPEC at a culture-based prevalence of 18%. In contrast, quantitative PCR detected the presence of the gene for intimin ( eae ) in feces from 42% of kittens. aEPEC was isolated from kittens with and without diarrhea. However, kittens with diarrhea harbored significantly larger quantities of aEPEC than kittens without diarrhea. Kittens with aEPEC had a significantly greater severity of small intestinal and colonic lesions and were significantly more likely to have required subcutaneous fluid administration. These findings identify aEPEC to be prevalent in kittens and a significant primary or contributing cause of intestinal inflammation, diarrhea, dehydration, and associated mortality in kittens.

Full Text Available Calf enlargement following sciatica is a rare condition. It is reported the case of a 28-year-old woman who complained of repeated episodes of lower back pain radiating into the left buttock and foot. One year after the beginning of her symptoms, she noticed enlargement of her left calf. X-ray studies disclosed L5-S1 disk degeneration. EMG showed muscle denervation with normal motor conduction velocity. Open biopsies of the gastrocnemius muscles were performed. The left gastrocnemius muscle showed hypertrophic type 2 fibers in comparison with the right gastrocnemius. Electron microscopy showed mildly increased number of mitochondria in these fibers. A satisfactory explanation for denervation hypertrophy has yet to be provided.

In this report a case of actinomycosis in a five-month-old Holstein calf is described. The patient displayed a hard and immobile swelling in the mandible and fever. Computed tomography (CT) imaging of the skull was performed under deep sedation and revealed an asymmetrical appearance of the mandible with the presence of intra-mandibular hypodense lesions. Haematologic and serum biochemical profiles revealed leukocytosis, neutrophilia, hypoalbuminaemia and hypergammaglobulinaemia. Treatment consisted of flushing the lesion and administration of antibiotics and non-steroidal anti-inflammatory drugs. The calf responded to therapy and had recovered almost completely four months later. The present case indicates that CT is an effective non-invasive means of identifying mandibular lesions in cattle

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

Directory of Open Access Journals (Sweden)

Antonietta Giannattasio

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

Under adverse obstetrical conditions, appropriate supervision and assistance during the immediate neonatal period are of the utmost importance, especially for weak calves. The aim of this study was to establish the effects of dystocia and oxytocin infusion on neonatal vitality, acid-base balance, and electrolyte and haematological homeostasis of dairy calves. Data were collected for 30 Holstein calves which were allocated to three groups: normal calving (n = 10); dystocia with mild to severe obstetric assistance (n = 10); and uterine inertia treated with oxytocin (n = 10). All 30 calves exhibited normothermia at birth, but had a significant decrease in body temperature after 60 min. Dystocic calves had lower Apgar scores than calves in the other two groups, and had respiratory and metabolic acidosis. Calves from normal calvings had normal blood pH, but base excess below the reference range. The mean partial pressure (Pa) of oxygen of calves whose dam had been treated with oxytocin was lower than that of calves from normal calvings. In all experimental groups, there was improvement in metabolic status in the first 60 min postpartum as PaCO2 values significantly decreased. All calves had normonatraemia, normokalaemia and normochloridaemia during the study period, but calves born to dams treated with oxytocin had a higher sodium concentration than those in the two other groups.

Erteld, E; Krohn, J; Dzhakupov, I T; Wehrend, A

2014-01-01

To summarize the available literature on the therapy of uterine torsion in cattle and the consequences for cow and calf. Analysis of the literature using electronic libraries (PubMed, Medline), German veterinary medical journals and obstetrical textbooks. The therapy includes the attempt to rotate the uterus back into its physiological position. Direct and indirect methods of retorsion are available and applied according to the case conditions. Subsequently, the extraction of the calf can be performed via vaginal delivery or caesarean section. The presence of uterine torsion always leads to dystocia. Following a successful retorsion, the time and degree of uterine torsion strongly influence the progress of the birth. The prognosis also depends on the aforementioned factors and varies between good to unsuccessful. The vitality of the calf displays great variation depending on the literature (14-90%), however, is generally greater under field than clinical conditions. Focussing on the puerperal development of the cow, all grades from mild irritations of the uterine involution to fatal complications occur. The influence on fertility depends on the progress of the birth and existing secondary complications. The risk for electrolyte disturbances is increased (approximately 50%) as is the risk of birth-associated injuries (approximately 20%). The incidence of placental retention varies widely between different authors (3-52%).

The aim of our study was to assess a group of patients with calf muscle tears and evaluate the integrity of the connective tissue boundaries and interfaces. Further, we propose a novel MRI grading system based on integrity of the connective tissue and assess any correlation between the grading score and time to return to play. We have also reviewed the anatomy of the calf muscles. We retrospectively evaluated 100 consecutive patients with clinical suspicion and MRI confirmation of calf muscle injury. We evaluated each calf muscle tear with MRI for the particular muscle injured, location of injury within the muscle and integrity of the connective tissue structure at the interface. The muscle tears were graded 0-3 depending on the degree of muscle and connective tissue injury. The time to return to play for each patient and each injury was found from the injury records and respective sports doctors. In 100 patients, 114 injuries were detected. Connective tissue involvement was observed in 63 out of 100 patients and failure (grade 3 injury) in 18. Mean time to return to play with grade 0 injuries was 8 days, grade 1 tears was 17 days, grade 2 tears was 25 days and grade 3 tears was 48 days (pmuscle tears. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Prevalence of Giardia duodenalis assemblages in weaned cattle on cow-calf operations in the United States.

Science.gov (United States)

Santin, Monica; Dargatz, David; Fayer, Ronald

2012-02-10

To determine the prevalence of Giardia duodenalis in weaned beef calves on cow-calf operations in the United States, fecal specimens were collected from 819 calves (6-18 months of age) from 49 operations. After cleaning and concentration procedures to maximize recovery of cysts from feces, DNA was extracted from each of the 819 specimens. The presence of G. duodenalis was determined by nested PCR of a fragment of the SSU rRNA gene. All positive PCR products were subjected to sequence analysis. The overall sample level prevalence of Giardia was 33.5% with prevalence ranging from 0 to 100% among operations. The highest within herd prevalence of infected beef calves was found in one cow-calf operation from the South region (100%), followed by a cow-calf operation from the West region (90%), and three cow-calf operations from the Midwest region (87.5, 85, and 85%). Giardia was not detected in samples from 7 operations including 5 cow-calf operations from the South region, and 1 cow-calf operation each from the Midwest and West regions. Molecular analysis of the Giardia-positive samples identified assemblage E (or E-like) in 31.7% of all samples (260/819) and assemblage A in 1.2% (10/819). A mixed infection with assemblages A and E was observed in four calves from an operation in Midwest region. The potentially zoonotic assemblage A was detected in specimens from four operations in Midwest region. These findings indicate that most G. duodenalis found in weaned beef calves was assemblage E which represents no known zoonotic threat. However, the presence of assemblage A in a small number of animals poses a potential risk of infection to humans. Published by Elsevier B.V.

A Calf rearing package of Individual (mobile) pens , milk and fodder feeding was introduced on smallholder farms of Bahati Division, Nakuru District, Kenya. The study investigated the effects of changes in Calf rearing practices on calf performance and the responses of the production systems to the investigations. 46 farmers were selected on the basis of their willingness to participate in the study and were allocated to Control (23 and Test (23). both types of farmers were trained but only test farms received building materials and forage seeds. Socio-economic and calf performance data were collected. Calves were supplemented with sweet potato vines (SPV) + Green leaf desmodium (DES) and/or fodder shrubs (FOD) Leucaena leucocephala and Sesbania sesban. Analysis of variance (ANOVA) models and Chi-square test were applied on the data collected. The study revealed that there were variations in off-farm, livestock and crop incomes. The gross Margins (GM) were higher (P < 0.01) for the test than the Control farmers. Calves raised in Test farms Demonstrated higher (P < 0.05) growth rates than those in Control farms (370 versus 307 g/d). Female calves gained (P < 0.05) 57 g/d more than mal calves.Those with assorted farm grown legumes (SPV + FOD) performed better (375 and 417 g/d, respectively) compared to those supplemented with SPV alone or not supplemented (345 and 321 g/d, respectively). Improved calf performance in Test farms suggests that, farm grown forage legumes, could be used as a cheap alternative protein supplement by resource-poor farmers. Calf mortality rates for Control farms (33%) were higher (P < 0.05) than those for Test farms (12.5%). The study concluded that the interventions/measures taken improve the overall performance of calves on-farm

Effects of black bear relocation on elk calf recruitment at Great Smoky Mountains National Park

Science.gov (United States)

Yarkovich, J.; Clark, J.D.; Murrow, J.L.

2011-01-01

Previous research from 2001 to 2006 on an experimentally released elk (Cervus elaphus) population at Great Smoky Mountains National Park (GSMNP or Park) indicated that calf recruitment (i.e., calves reaching 1 yr of age per adult female elk) was low (0.306, total SE = 0.090) resulting in low or negative population growth (λ = 0.996, 95% CI = 0.945–1.047). Black bear (Ursus americanus) predation was the primary calf mortality factor. From 2006 to 2008, we trapped and relocated 49 bears (30 of which were radiocollared) from the primary calving areas in the Park and radiomonitored 67 (28 M:39 F) adult elk and 42 calves to compare vital rates and population growth with the earlier study. A model with annual calf recruitment rate correlating with the number of bears relocated each year was supported (ΔAICc = 0.000; β = 0.070, 95% CI = 0.028–0.112) and a model with annual calf recruitment differing from before to during bear relocation revealed an increase to 0.544 (total SE = 0.098; β = −1.092, 95% CI = −1.180 to −0.375). Using vital rates and estimates of process standard errors observed during our study, 25-yr simulations maintained a mean positive growth rate in 100% of the stochastic trials with λ averaging 1.118 (95% CI = 1.096–1.140), an increase compared with rates before bear relocation. A life table response experiment revealed that increases in population growth were mostly (67.1%) due to changes in calf recruitment. We speculate that behavioral adaptation of the elk since release also contributed to the observed increases in recruitment and population growth. Our results suggest that managers interested in elk reintroduction within bear range should consider bear relocation as a temporary means of increasing calf recruitment.

Malaria parasitemia and childhood diarrhea in a peri-urban area of Guinea-Bissau

DEFF Research Database (Denmark)

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

1999-01-01

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

Hartmann, H.; Finsterbusch, L.; Rudolf, C.; Meyer, H.; Schweinitz, P.

1988-01-01

Volumes, biological half-life values, and transfer rates of the fluid compartments of whole-body water and extracellular space were recorded from 37 clinically intact calves, aged between two days and six weeks, as well as from 50 animals with diarrhea, aged between four days and six weeks. The effect of infusion on fluid spaces of calves with diarrhea was also investigated. Transfer rates of whole-body water and extracellular space were 4.6 ml or 1.5 mlkg -1 hr -1 for calves aged two weeks and were 6.2 ml or 1.8 mlkg -1 hr -1 for animals between five and six weeks of age. Diarrhea in young calves was found to increase the transfer rate of whole-body water to 6.3 mlkg -1 hr -1 (137 per cent) in surviving individuals or to 12.1 mlkg -1 hr -1 (263 per cent) in those individuals which died within two days. The transfer rates for extracellular space increased even more clearly to 2.4 mlkg -1 hr -1 (160 per cent) in survivors and to 7.4 mlkg -1 hr -1 (493 per cent) in dying calves. The reduced volumes of fluid spaces were largely normalized at least by the end of infusion in calves with moderate to severe diarrhea which received intravenous applications of 1.0 l or 1.5 l of an electrolyte-glucose solution. The calves thus treated still exhibited, however, clearly increased transfer rates for???

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

This work describes findings in a fattened calf, which were seen in a routine slaughter. The most important findings by the meat inspector were diffuse, black spots between 2 and 70 mm in diameter. This hyperpigmentation was observed on the entire carcass as well as on the outside and inside of all internal organs. Removal of the spinal cord produced black colored liquor. Subsequent microbiological examination of the meat resulted in sterile findings. The muscle pH was 5.8. On histological examination many macrophages containing melanin were found in the lung and liver. Based on these findings the diagnosis of Melanosis maculosa was made.

Full Text Available Abstract Background Diarrhea mortality remains a leading cause of child death and rotavirus vaccine an effective tool for preventing severe rotavirus diarrhea. New data suggest vaccine efficacy may vary by region. Methods We reviewed published vaccine efficacy trials to estimate a regional-specific effect of vaccine efficacy on severe rotavirus diarrhea and hospitalizations. We assessed the quality of evidence using a standard protocol and conducted meta-analyses where more than 1 data point was available. Results Rotavirus vaccine prevented severe rotavirus episodes in all regions; 81% of episodes in Latin America, 42.7% of episodes in high-mortality Asia, 50% of episodes in sub-Saharan Africa, 88% of episodes low-mortality Asia and North Africa, and 91% of episodes in developed countries. The effect sizes observed for preventing severe rotavirus diarrhea will be used in LiST as the effect size for rotavirus vaccine on rotavirus-specific diarrhea mortality. Conclusions Vaccine trials have not measured the effect of vaccine on diarrhea mortality. The overall quality of the evidence and consistency observed across studies suggests that estimating mortality based on a severe morbidity reduction is highly plausible.

Neonatal survival and juvenile recruitment are crucial to maintaining viable elk (Cervus elaphus) populations. Neonate survival is known to be influenced by many factors, including bed-site selection. Although neonates select the actual bed-site location, they must do so within the larger calf-rearing area selected by the mother. As calves age, habitat selection should change to meet the changing needs of the growing calf. Our main objectives were to characterize habitat selection at 2 spatial scales and in areas with different predator assemblages in New Mexico. We evaluated bed-site selection by calves and calf-rearing area selection by adult females. We captured 108 elk calves by hand and fitted them with ear tag transmitters in two areas in New Mexico: the Valle Vidal and Blue Range Wolf Recovery Area. In both study areas, we found that concealing cover structure and distance to that cover influenced bed-site selection of young calves (i.e., age). Older calves (i.e., 3–10 weeks of age) still selected areas in relation to distance to cover, but also preferred areas with higher visibility. At the larger spatial scale of calf-rearing habitat selection by the adult female, concealing cover (e.g., rocks, shrubs, and logs) and other variables important to the hiding calves were still in the most supported models, but selection was also influenced by forage availability and indices of forage quality. Studies that seek to obtain insight into microhabitat selection of ungulate neonates should consider selection by the neonate and selection by the adult female, changes in selection as neonates age, and potential selection differences in areas of differing predation risk. By considering these influences together and at multiple scales, studies can achieve a broader understanding of neonatal ungulate habitat requirements. 

Diagnosis and Management of AIDS-related Diarrhea

1996-01-01

Full Text Available The spectrum of illness associated with the acquired immunodeficiency syndrome (AIDS has been increasing since the initial description in 1981. While virtually all organ systems may be affected, the gastrointestinal tract appears to be a major target. Diarrhea is the most common symptom, affecting up to half of all AIDS patients during the course of their disease. Although diarrhea occurs frequently, its optimal management remains controversial. An extensive evaluation including stool studies and endoscopic biopsies of both the colon and small intestine has been widely recommended to identify all potential pathogenic organisms. An alternative approach is a more limited evaluation consisting of stool and blood cultures followed by symptomatic treatment with antidiarrheal agents if no specific organisms are identified. The clinical presentation of the most common opportunistic pathogens are reviewed, including several recently discovered organisms. Recommendations for treatment are followed by a brief discussion of management strategies used to care for patients with AIDS-related diarrhea.

Role of FODMAP content in enteral nutrition-associated diarrhea.

Science.gov (United States)

Halmos, Emma P

2013-12-01

Gastrointestinal symptoms including diarrhea are common complications of enteral nutrition (EN); however, the cause is unclear. Mode of EN delivery that alters digestion and possibly absorption is suggested to contribute to the high incidence of diarrhea; however, enteral formula is frequently blamed. Most research has focused on fiber-supplemented EN, with a meta-analysis showing that fiber reduces the incidence of diarrhea in non-intensive care unit studies. Other hypotheses include formula osmolality and FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) content. FODMAPs are poorly absorbed short-chain carbohydrates that exert an osmotic effect. Dietary FODMAPs have been shown to reduce gastrointestinal symptoms, including diarrhea, in those with irritable bowel syndrome and, given a high-enough dose, will induce a laxative effect in most people. As FODMAPs are commonly added to enteral formula and EN is frequently used as the main source of nutrition, it is reasonable to hypothesize that EN provides more FODMAPs than usual dietary intake and increases risk for developing diarrhea. This hypothesis was assessed through a retrospective study showing that the standard-use enteral formula Isosource 1.5 had a protective effect of developing diarrhea. The only characteristic unique to Isosource 1.5 was the lower FODMAP content as determined through methodologies previously validated for food analysis. Methodologies for application to enteral formulas are currently undergoing formal validation. Once confirmed for application in enteral formula, future directions include FODMAP analysis of specific ingredients to increase understanding of potential problems associated with enteral formula and a randomized, controlled trial investigating the role of formula FODMAP content. © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

Stiffness and shortening of the calf muscle due to neural or mechanical factors can profoundly affect motor function. The aim of this study was to investigate non-neurally mediated calf-muscle tightness in children with cerebral palsy (CP) before and after botulinum toxin type A (BoNT-A) injection. Sixteen children with spastic CP (seven females, nine males; eight at Gross Motor Function Classification System level I, eight at level II; age range 4-10 y) and calf muscle spasticity were tested before and during the pharmaceutically active phase after injection of BoNT-A. Measures of passive muscle compliance and viscoelastic responses, hysteresis, and the gradient of the torque-angle curve were computed and compared before and after injection. Although there was a slight, but significant increase in ankle range of motion after BoNT-A injection and a small, significant decrease in the torque required to achieve plantigrade and 5° of dorsiflexion, no significant difference in myotendinous stiffness or hysteresis were detected after BoNT-A injection. Despite any effect on neurally mediated responses, the compliance of the calf muscle was not changed and the muscle continued to offer significant resistance to passive motion of the ankle. These findings suggest that additional treatment approaches are required to supplement the effects of BoNT-A injections when managing children with calf muscle spasticity. © The Authors.

Records of Holstein cows from March 1992 to April 2008 from 194 large herds and comprising from 402,716 records for productive traits to 178,344 records of somatic cell count were used to study the effect of calf sex in different parities and calving season on the subsequent productive, reproductive and health traits in Holstein cows. T-test procedure of SAS software was used to investigate the effect of calf sex and season of calving on aforementioned traits. Cows with female calves had higher milk and fat yield, persistency of milk and fat yield and longer lactation length, while cows that gave birth to male calves had shorter calving interval and longer productive life. Also, cows with female calves had higher milk yield per day of lactation in the first two parities, but there was no difference in milk yield per day of lactation for parities ≥ 3. There was no relationship among mean somatic cell count and sex of born calf. Fall calves had the highest adjusted milk yield and milk yield per day of lactation, however, winter calves had the longest lactation lengthand productive life and the highest somatic cell count. Results from this study demonstrate that it seems necessary to consider the effect of calf sex on aforementioned traits when making decision to use sexed semen or conventional semen. (Author)

Meuris

1995-03-01

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

Full Text Available Background and ObjectivesDiarrhea which leads to zinc wasting from body is one of the major causes of mortality in children around the world. Zinc is one of the elements that facilitate the repair of stomach and intestinal mucosa, stimulation of immune system, control and transfer of water and electrolytes in our body. World Health Organization (WHO recommends use of zinc sulfate in all cases of diarrhea in addition to replacement of fluids and continuation of feeding in treatment of children with diarrhea. The objective of this study is evaluation of the effect of zinc sulfate (ZnSo4 on the recovery duration and appetite in children with diarrhea. This study evaluates the effect of ZnSo4 in prevention of respiratory infection and diarrhea for two months after taking the ZnSo4.MethodsTwo groups of children (total n=153 with non dysenteric acute diarrhea who were hospitalized in Qom’s children hospital in 2007 were used in this clinical trials. Sixty four of these children (n=64 were randomized to the study group and eighty nine (n=89 to the control group. The children in the control group received the standard therapy (fluid & electrolyte therapy &continuation of feeding for treatment of diarrhea and the children in the study group received standard treatment, and 5 mg of zinc sulfate twice daily for two weeks. Neither of these two groups received any anti diarrhea therapy and/or antibiotics. Both groups were monitored for occurrence of new episodes of diarrhea and/or respiratory tract infection for two months after the end of their hospitalization. T-score and Fisher tools were used for statistical analysis of the gathered data.ResultsChildren in two groups had several similarities such as gender, decrease in appetite, nausea and vomiting. There was not a significant difference between two groups with respect to the length of recovery, new incidence of diarrhea, and respiratory tract infection within two months after hospitalization.

Anthropogenic climate change will likely increase diarrhea rates for communities with inadequate water, sanitation, or hygiene facilities including those with intermittent water supplies. Current approaches to study these impacts typically focus on the effect of temperature on all-cause diarrhea while excluding precipitation and diarrhea etiology while not providing actionable adaptation strategies. We develop a partially mechanistic, systems approach to estimate future diarrhea prevalence and design adaptation strategies. The model incorporates downscaled global climate models, water quality data, quantitative microbial risk assessment, and pathogen prevalence in an agent-based modeling framework incorporating precipitation and diarrhea etiology. It is informed using water quality and diarrhea data from Hubli-Dharwad, India-a city with an intermittent piped water supply exhibiting seasonal water quality variability vulnerable to climate change. We predict all-cause diarrhea prevalence to increase by 4.9% (Range: 1.5-9.0%) by 2011-2030, 11.9% (Range: 7.1-18.2%) by 2046-2065, and 18.2% (Range: 9.1-26.2%) by 2080-2099. Rainfall is an important modifying factor. Rotavirus prevalence is estimated to decline by 10.5% with Cryptosporidium and E. coli prevalence increasing by 9.9% and 6.3%, respectively, by 2080-2099 in this setting. These results suggest that ceramic water filters would be recommended as a climate adaptation strategy over chlorination. This work highlights the vulnerability of intermittent water supplies to climate change and the urgent need for improvements.

Aim: To determine whether soft-tissue thickness of the calf measured using MRI could be valid for assessing unilateral lower extremity lymphoedema (LEL) secondary to cervical and endometrial cancer treatments. Materials and methods: Seventy women with unilateral LEL and 25 without LEL after cervical or endometrial cancer treatments underwent MRI examinations of their calves. Total thickness of soft-tissue (TT), muscle thickness (MT), and subcutaneous tissue thickness (STT) of the calf, and the difference between the affected and contralateral unaffected calf regarding TT (DTT), MT (DMT), and STT (DSTT) were obtained using fat-suppressed T2-weighted imaging in the middle of the calves. The volume of the calf and difference in volume (DV) between calves were obtained by the method of water displacement. Statistical analysis was performed to determine the validity of MRI measurements by volume measurements in staging LEL. Results: There was a close correlation between volume and TT for the affected (r = 0.927) or unaffected calves (r = 0.896). STT of the affected calf, and DTT or DSTT of the calves were closely correlated with volume of the affected calf or DV of the calves (all p < 0.05). Multivariate analysis showed significant differences in TT, STT, volume of the affected calf, DTT, DSTT, and DV between stages except in volume of the affected calf or in DV between stage 0 and 1. For staging LEL, DSTT showed the best discrimination ability among all the parameters. Conclusions: Soft-tissue thickness of the calf measured at MRI could be valid for quantitatively staging unilateral LEL, and DSTT of the calves could be the best classifying factor. - Highlights: • The soft tissue thickness of calves on MRI could quantitatively assess secondary LEL. • Calf soft tissue thickness indicated concurrent or construct validity of calf volume. • The difference of subcutaneous tissue thickness of calves could be used to stage LEL

A Rare Case of Chronic Diarrhea in an Elderly Male

Full Text Available Chronic diarrhea is a common condition in older age groups, and many patients do not seek medical attention unless their diarrhea is associated with other symptoms, such as weight loss, gastrointestinal bleeding or abdominal pain. It is a critical condition in the elderly, especially with systemic disease. We report the case of an elderly patient with chronic diarrhea secondary to intestinal capillariasis. Human intestinal capillariasis is a rare parasitosis of the gastrointestinal tract, which may be a fatal disease if early treatment is not given. The clinical hallmarks of capillariasis include chronic diarrhea, abdominal pain, borborygmi, marked weight loss, protein and electrolyte loss, and cachexia. Most patients die from electrolyte loss resulting in heart failure and/or septicemia. Taiwan, particularly in Taitung County, is a Capillaria-prevalent area. Thus, parasitosis must be considered in the differential diagnosis of patients with debilitating chronic diarrhea, especially in the elderly aboriginal population of Taitung County. A careful dietary and travel history is important in any such case; but even in the absence of clear-cut exposure, a parasitic infection should be considered and carefully investigated.

A growing body of evidence suggests health-promoting effects of kefir consumption on different nonruminant species, leading to the speculation that kefir may act as a probiotic and benefit calf performance and health. Our objectives were to determine effects of feeding kefir on performance and health of calves in the first 70d of life. Thirty 3-d-old female Holstein calves (body weight=38.2±3.1kg) were blocked by initial body weight and assigned randomly to 1 of 3 treatments (1 calf per pen; 10 pens per treatment). Kefir was added to whole milk (vol/vol) at 0:1 (control; KF0), 1:3 (KF1), or 1:1 (KF2) and fed twice per day (0800 and 1600h) from d3 through 45 and then once per day until weaning, which occurred on d50. Pre- and postweaning intake of starter, daily body weight gain, and gain-to-feed ratio exhibited no difference among treatments. Adding kefir to whole milk fed directly to calves had no effect on concentration of blood metabolites collected on d20, 40, and 70. Body length on d50 (weaning) and 70 was greater in kefir-fed calves. Kefir intake improved fecal scores and reduced days with diarrhea during the first 2wk of life. Apparent digestibility of organic matter, ether extract, crude protein, and neutral detergent fiber remained unaffected by treatment. Overall, it appears that directly feeding kefir to calves during the preweaning period did not improve the performance of calves under the conditions of the current study; however, its consumption marginally improved body length and fecal consistency in the first weeks of life, which is an important concern in intensive calf-rearing systems. Feeding kefir to neonatal calves may be a viable approach to improve the health of calves in commercial calf-rearing operations, although to validate its health-promoting effects additional research is needed to investigate its effects under different calf-rearing conditions.

2010-03-01

Environmental stressors, such as high fly density, can affect calf well-being. Sodium bisulfate (SBS) is an acidifier that reduces the pH of flooring and bedding, creating a medium that neither bacteria nor immature flies (also known as larvae or maggots) can thrive in. Two experiments were conducted to investigate the application of SBS to a mixture of rice hull calf bedding and calf slurry (BED) to reduce house fly (Musca domestica L.) larval density and the abundance of bacteria. In experiment 1, dish pans containing 1L of BED and 3,000 house fly eggs were treated with SBS at concentrations of 0, 8.9, 17.7, and 26.5g of SBS/0.05m(2) of BED (CON, LOW, MED, and HIGH, respectively), with each SBS concentration applied to 4 individual pans (16 pans total). Reapplication of the same SBS concentrations in each pan occurred 3 times/wk throughout the 23-d trial. Larval house fly survival was significantly reduced in all pans with SBS relative to CON pans, with lowest survival rates in the MED and HIGH pans (99% and 100% reduction, respectively). The mean pH for each treatment was inversely related to the SBS concentration. In experiment 2, pans containing 1L of BED and 3,000 house fly eggs were treated with either 0g of SBS (CON), 8.9g of SBS/0.05m(2) of BED with reapplication of the acidifier 3 times/wk (SB3x), or 8.9g of SBS/0.05m(2) of BED applied only once at 48h before the end of the 8 d-trial (SB48). Larval house fly survival and bacterial concentrations were reduced (90% larval reduction and 68% bacterial reduction) in the SB3x treatment relative to the CON. Mean pH was also reduced in SB3x pans relative to CON or SB48 pans. Overall, acidification of calf BED using the acidifier SBS resulted in a reduction of bacteria and house fly larval survival. This form of fly control might be expected to reduce adult fly production and, therefore, fly-related stress in calves.

Spruelike Enteropathy Associated with Olmesartan: An Unusual Case of Severe Diarrhea

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

Enteral Formula Containing Egg Yolk Lecithin Improves Diarrhea.

Science.gov (United States)

Akashi, Tetsuro; Muto, Ayano; Takahashi, Yayoi; Nishiyama, Hiroshi

2017-09-01

Diarrhea often occurs during enteral nutrition. Recently, several reports showed that diarrhea improves by adding egg yolk lecithin, an emulsifier, in an enteral formula. Therefore, we evaluated if this combination could improve diarrhea outcomes. We retrospectively investigated the inhibitory effects on watery stools by replacing a polymeric fomula with that containing egg yolk lecithin. Then, we investigated the emulsion stability in vitro. Next, we examined the lipid absorption using different emulsifiers among bile duct-ligated rats and assessed whether egg yolk lecithin, medium-chain triglyceride, and dietary fiber can improve diarrhea outcomes in a rat model of short bowel syndrome. Stool consistency or frequency improved on the day after using the aforementioned combination in 13/14 patients. Average particle size of the egg yolk lecithin emulsifier did not change by adding artificial gastric juice, whereas that of soy lecithin and synthetic emulsifiers increased. Serum triglyceride concentrations were significantly higher in the egg yolk lecithin group compared with the soybean lecithin and synthetic emulsifier groups in bile duct-ligated rats. In rats with short bowels, the fecal consistency was a significant looser the dietary fiber (+) group than the egg yolk lecithin (+) groups from day 6 of test meal feedings. The fecal consistency was also a significant looser the egg yolk lecithin (-) group than the egg yolk lecithin (+) groups from day 4 of test meal feeding. The fecal consistency was no significant difference between the medium-chain triglycerides (-) and egg yolk lecithin (+) groups. Enteral formula emulsified with egg yolk lecithin promotes lipid absorption by preventing the destruction of emulsified substances by gastric acid. This enteral formula improved diarrhea and should reduce the burden on patients and healthcare workers.

Lactobacillus rhamnosus strain GG is a potential probiotic for calves

2004-01-01

Abstract Diarrhea is a common occurrence in neonatal calves. Several veterinary probiotics claiming to prevent or treat calf diarrhea are available, but have not been well studied. This study assessed the capability of Lactobacillus rhamnosus strain GG (LGG) to maintain viability in the gastrointestinal tract of calves. We also determined whether LGG can be administered in an oral rehydration solution (ORS) without compromising the efficacy of the ORS or the viability of LGG, and whether LGG produces D-lactate or not. To investigate the intestinal survival of LGG, 15 calves were randomized into 3 groups and LGG was administered orally with their morning milk feeding on 3 consecutive days at a low (LD), medium (MD), or high (HD) dosage. Fecal samples were collected on days 0 (control), 1, 2, 3, 5, and 7 and incubated for 72 h on deMan, Rogosa, Sharpe agar. Twenty-four hours after the 1st feeding, LGG was recovered from 1 out of 5 calves in the LD group, 4 out of 5 calves in the MD group, and 5 out of 5 calves in the HD group. To determine if LGG caused the glucose levels in the ORS to drop below effective levels, 1.5 L of the ORS was incubated with LGG for 2 h at 37°C and the glucose concentration was measured every 20 min using a glucose meter. This ORS was then further incubated for 10 h and aliquots analyzed by high performance liquid chromatography to determine if D-lactate was produced by LGG. Glucose concentrations did not change over the 2 h of incubation, and no D-lactate was produced after 48 h. The LGG maintained viability in ORS. Therefore, this study demonstrated that LGG survives intestinal transit in the young calf, produces no D-lactate, and can be administered in an ORS. PMID:15581218

For children under 5 years of age, 1700 000 000 episodes of diarrhea are seen worldwide, and death occurs in 700 000 of these cases due to diarrhea. Rotavirus is an important cause of diarrhea in this age group, and many studies have shown that vitamin D plays a pivotal role in the immune system, as well as in antimicrobial peptide gene expression. In addition, lower vitamin D has been correlated with higher rates of infectious diseases such as respiratory tract infection, tuberculosis, and viral infection. Seventy patients with rotaviral diarrhea and 67 healthy patients were enrolled in this study. Serum 25-hydroxy vitamin D(3) (25(OH)D(3)), parathormone, calcium, phosphate, alkaline phosphatase, complete blood count parameters, and C-reactive protein were compared between pre-school children hospitalized due to rotaviral diarrhea and healthy children. Additionally, birthweight, feeding habits in the first 6 months of life, vitamin D and multivitamin supplements, and rotaviral vaccinations were also evaluated in each group. There were no differences between the groups with regard to gender and age, but 25(OH)D(3) was significantly different: 14.6 ± 8.7 ng/mL in the rotaviral diarrhea patients versus 29.06 ± 6.51 ng/mL in the health controls (P vitamin D is associated with rotaviral diarrhea. This is the first study in the literature to show this, and this result needs to be repeated in larger controlled clinical studies. © 2015 Japan Pediatric Society.

Full Text Available Abstract Introduction Rupture of the distal musculotendinous junction of the medial head of the gastrocnemius, also known as "tennis leg", can be readily examined using a soft tissue ultrasound. Loss of muscle fiber continuity and the occurrence of bloody fluid accumulation can be observed using ultrasound with the patient in the prone position; however, some cases may have normal ultrasound findings in this conventional position. We report a case of a middle-aged man with tennis leg. Ultrasound examination had normal findings during the first two attempts. During the third attempt, with the patient's calf muscles examined in an unconventional knee flexed position, sonographic findings resembling tennis leg were detected. Case presentation A 60-year-old man in good health visited our rehabilitation clinic complaining of left calf muscle pain. On suspicion of a ruptured left medial head gastrocnemius muscle, a soft tissue ultrasound examination was performed. An ultrasound examination revealed symmetrical findings of bilateral calf muscles without evidence of muscle rupture. A roentgenogram of the left lower limb did not reveal any bony lesions. An ultrasound examination one week later also revealed negative sonographic findings. However, he still complained of persistent pain in his left calf area. A different ultrasound examination approach was then performed with the patient lying in the supine position with his knee flexed at 90 degrees. The transducer was then placed pointing upwards to examine the muscles and well-defined anechoic fluid collections with areas of hypoechoic surroundings were observed. Conclusion For patients suffering from calf muscle area pain and suspicion of tennis leg, a soft tissue ultrasound is a simple tool to confirm the diagnosis. However, in the case of negative sonographic findings, we recommend trying a different positional approach to examine the calf muscles by ultrasound before the diagnosis of tennis leg can

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

Background and Objectives

Diarrhea which leads to zinc wasting from body is one of the major causes of mortality in children around the world. Zinc is one of the elements that facilitate the repair of stomach and intestinal mucosa, stimulation of immune system, control and transfer of water and electrolytes in our body. World Health Organization (WHO recommends use of zinc sulfate in all cases of diarrhea in addition to replacement of fluids and continuation of feeding in treatment of children with diarrhea. The objective of this study is evaluation of the effect of zinc sulfate (ZnSo4 on the recovery duration and appetite in children with diarrhea. This study evaluates the effect of ZnSo4 in prevention of respiratory infection and diarrhea for two months after taking the ZnSo4.

Methods

Two groups of children (total n=153 with non dysenteric acute diarrhea who were hospitalized in Qom’s children hospital in 2007 were used in this clinical trials. Sixty four of these children (n=64 were randomized to the study group and eighty nine (n=89 to the control group. The children in the control group received the standard therapy (fluid & electrolyte therapy &continuation of feeding  for treatment of diarrhea and the children in the study group received standard treatment, and 5 mg of zinc sulfate twice daily for two weeks. Neither of these two groups received any anti diarrhea therapy and/or antibiotics. Both groups were monitored for occurrence of new episodes of diarrhea and/or respiratory tract infection for two months after the end of their hospitalization. T-score and Fisher tools were used for statistical analysis of the gathered data.

Results

Children in two groups had several similarities such as gender, decrease in appetite, nausea and vomiting. There was not a significant difference between two groups with respect to the length of recovery, new incidence of

Full Text Available Diarrhea is a global health problem with high morbidity and mortality. In developing countries, acute diarrhea is most commonly caused by infectious pathogens. Regardless of the cause, diarrhea is primarily treated by fluid replacement therapy to decrease the risk of dehydration and death, although it does not affect the duration of diarrhea. Probiotics are able to shorten the duration of diarrhea in children, but its efficacy in adults is unclear. This study aimed to evaluate the benefit of probiotic in reducing the duration of acute diarrhea in adults as compared to placebo. Systematic search was done using four databases: PubMed, Scopus, ProQuest, and Embase, without limit on the year of publication. Randomized clinical trials were selected as the appropriate study design to answer the clinical question and two studies were considered relevant for appraisal. In conclusion, probiotics could improve the recovery of acute infectious diarrhea in adults (level of evidence 1b however more studies should be carried out since only very few strains of probiotics have been investigated.

Calf muscle strains have become increasingly prevalent in recent seasons of the Australian Football League (AFL) and represent a significant cause of time lost from competition. The purpose of this study was to examine the association between MRI features of calf muscle strains and games missed and to thereby identify parameters that are of prognostic value. A retrospective analysis of MRI scans of AFL players with calf strains referred to a musculoskeletal radiology clinic over a 5-year period (2008-2012) was performed. The muscle(s) and muscle component affected, the site and size of strain, and the presence of an intramuscular tendon tear or intermuscular fluid were recorded. These data were cross-referenced with whether a player missed at least one game. Imaging features of prognostic value were thus identified. Sixty-three athletes had MRI scans for calf muscle strains. Soleus strains were more common than strains of other muscles. Players with soleus strains were more likely to miss at least one game if they had multiple muscle involvement (p = 0.017), musculotendinous junction strains (p = 0.046), and deep strains (p = 0.036). In a combined analysis of gastrocnemius and soleus strains, intramuscular tendon tears were observed in a significantly greater proportion of players who missed games (p = 0.010). Amongst AFL players with calf injuries, there is an association between missing at least one game and multiple muscle involvement, musculotendinous junction strains, deep strain location, and intramuscular tendon tears. In this setting, MRI may therefore provide prognostic information to help guide return-to-play decisions. (orig.)

The use of traditional medicine as an alternative source of cure for many ailments has played an important role in health care delivery in both developing and developed countries. Byrsocarpus coccineus Schum and Thonn ( Connaraceae ) is used in traditional medicine for treatment of various disease conditions, including diarrhea. The anti-diarrhea activity of the root bark aqueous extract of B. coccineus was investigated in this study. Acute toxicity evaluation of the aqueous extract of B. coccineus root bark was performed in exposed rats. Diarrhea was induced in exposed rats with castor oil, and the effect of the extract on castor oil-induced gastrointestinal motility and enteropooling was consequently investigated. In the acute toxicity study, the extract caused no death in treated rats nor produced signs of delayed toxicity, even at 5000 mg/kg. The aqueous root bark extract of B. coccineus also decreased the distance travelled by activated charcoal in the gastrointestinal tract of treated rats when compared to control rats. Results of castor oil-induced enteropooling revealed slight reduction in the weight of intestinal contents of treated rats compared to control rats. There was significant (pcastor oil-induced diarrhea at 100 mg/kg dose with 74.96% inhibition of defecation. The study demonstrated the anti-diarrheic property of the aqueous extract of B. coccineus root bark as currently exploited in our traditional herbal therapy.

Serological indicators of general condition would be helpful for monitoring or assessing ungulate wildlife. Toward that end, we report the 1st reference values for 2 cytokines, interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-??), in neonatal elk (Cervus elaphus). We obtained blood samples from 140 calves ??? 6 days old in Yellowstone National Park during summer 2003-2005. TL-6 values ranged from 0 to 1.21 pg/ml with a median of 0.03 pg/ml. TNF-?? values ranged from 0 to 225.43 pg/ml with a median of 1.85 pg/ml. IL-6 and TNF-?? concentrations were not significant predictors of elk calf survival through 21 days. Development of ungulate-based IL-6 and TNF-?? assays that provide greater sensitivity than cross-reacting human-based assays could be helpful in monitoring ungulate condition and health status comparisons among herds. Such information could provide indirect assessments of range quality or environmental influences among herds.

Impact of antibiotics on necrotizing enterocolitis and antibiotic-associated diarrhea

Silverman, Michael A.; Konnikova, Liza; Gerber, Jeffrey S.

2017-01-01

Summary Antibiotics induce changes or dysbiosis of the intestinal microbiome. These antibiotic-induce changes may contribute to the pathogenesis of necrotizing enterocolitis (NEC) and antibiotic-associated diarrhea (AAD). Studies are beginning to unravel the contribution of specific groups of microbes to these diseases—most notably Gammaproteobacteria for NEC and bile acid- and carbohydrate-metabolizing microbes for AAD. Antibiotic-associated diarrhea occurs when antibiotic treatment induces diarrhea by altering the metabolic function of the patient’s intestinal microbiota leading to either an osmotic or infectious diarrhea, most notably Clostridium difficile infection (CDI). Antibiotic therapy impairs the host microbiota’s ability to resist colonization or expansion of pathogenic bacteria. In the case of CDI, there is growing evidence that microbiota-mediated bile acid metabolism is critical in the pathogenesis of this infection. Probiotics or other microbiota-targeted therapies may provide effective strategies to prevent and treat NEC and AAD. PMID:28164853

Radiotherapy induced diarrhea and convulsive pain are severe side-effects of irradiation of the pelvis and the abdomen leading often to an interruption of the treatment. Up to now these side-effects were only treated symptomatically, prophylactic therapies are not known. During the years 1992 and 1993 174 patients who obtained radiotherapy in the pelvis or the abdomen because of different malignancies were observed referring to the diarrhea-prophylactic effect of Smectite (=Skilpin R ). 80 patients received Smectite at the beginning of radiotherapy, 94 patients of the controlgroup were treated with motility modifying drugs when diarrhea appeared. The following parameters were compared: Frequency, consistence and incontinence of stool, tenesmus and the onset of diarrhea. 67,0% (n=63) of the patients in the controlgroup developed diarrhea, whereas in the pretreated Smectite-group only 37,5% of the cases (n=30) developed diarrhea. The first appearance of diarrhea was at day 17 in the pretreated group and averagely at day 11 in the controlgroup. 44% of the patients in the controlgroup suffered from tenesmus versus 25% in the Smectite-group. In comparison to the symptomatic treatment of radiation enteritis the prophylactic application of Smectite is able to reduce the diarrhea from the beginning of raditherapy or at least to reduce the pathological frequency of stool and therefore to increase the quality of life.

Mycobacterium avium subsp. paratuberculosis (MAP) and Neospora caninum (NC) are two pathogens causing important production limiting diseases in the cattle industry. Significant impacts of MAP and NC have been reported on dairy cattle herds, but little is known about the importance, risk factors and transmission patterns in western Canadian cow-calf herds. In this cross-sectional study, the prevalence of MAP and NC infection in southwest Alberta cow-calf herds was estimated, risk factors for NC were identified, and the reproductive impacts of the two pathogens were assessed. Blood and fecal samples were collected from 840 cows on 28 cow-calf operations. Individual cow and herd management information was collected by self-administered questionnaires and one-on-one interviews. Bayesian estimates of the true prevalence of MAP and NC were computed, and bivariable and multivariable statistical analysis were done to assess the association between the NC serological status and ranch management risk factors, and the clinical effects of the two pathogens. Bayesian estimates of true prevalence indicated that 20% (95% probability interval: 8-38%) of herds had at least one MAP-positive cow, with a within-herd prevalence in positive herds of 22% (8-45%). From the Bayesian posterior distributions of NC prevalence, the median herd-level prevalence was 66% (33-95%) with 10% (4-21%) cow-level prevalence in positive herds. Multivariable analysis indicated that introducing purchased animals in the herd might increase the risk of NC. The negative association of NC with proper carcass disposal and presence of horses on ranch (possibly in relation to herd monitoring and guarding activities), may suggest the importance of wild carnivores in the dynamics of this pathogen in the study area. We also observed an association between MAP and NC serological status and the number of abortions. Additional studies should be done to further examine specific risk factors for MAP and NC, assess the

Functional bowel disorders (i.e., constipation and diarrhea) are characterized by abdominal pain, bloating, distention, and/or bowel habit abnormalities in the absence of obvious anatomic or physiologic abnormalities on routine diagnostic tests. These symptoms are attributable to gastrointestinal sensorimotor dysfunctions resulting from peripheral and/or central mechanisms. Available drugs target the underlying bowel disturbance (i.e., constipation, diarrhea, or both), supplemented when necessary by management of pain. Osmotic and stimulant laxatives, secretagogues, and serotonin 5-HT 4 receptor agonists are approved for treating constipation. Loperamide, anticholinergic agents, rifaximin, bile-acid binding agents, eluxadoline, and clonidine are used to treat diarrhea. Several exciting new compounds, some of which have been evaluated in humans, are currently under development. Copyright © 2017 Elsevier Ltd. All rights reserved.

Syndromic diarrhea (or trichohepatoenteric syndrome) is a rare congenital bowel disorder characterized by intractable diarrhea and woolly hair, and it has recently been associated with mutations in TTC37. Although databases report TTC37 as being the human ortholog of Ski3p, one of the yeast Ski-complex cofactors, this lead was not investigated in initial studies. The Ski complex is a multiprotein complex required for exosome-mediated RNA surveillance, including the regulation of normal mRNA and the decay of nonfunctional mRNA. Considering the fact that TTC37 is homologous to Ski3p, we explored a gene encoding another Ski-complex cofactor, SKIV2L, in six individuals presenting with typical syndromic diarrhea without variation in TTC37. We identified mutations in all six individuals. Our results show that mutations in genes encoding cofactors of the human Ski complex cause syndromic diarrhea, establishing a link between defects of the human exosome complex and a Mendelian disease.

In Zimbabwe, rotavirus accounted for 41%-56% of acute diarrhea hospitalizations before rotavirus vaccine introduction in 2014. We evaluated rotavirus vaccination impact on acute diarrhea- and rotavirus-related healthcare visits in children. We examined monthly and annual acute diarrhea and rotavirus test-positive hospitalizations and Accident and Emergency Department visits among children introduction (2012-2013) with postvaccine introduction (2015 and 2016) data for 2 of the hospitals. We examined monthly acute diarrhea hospitalizations by year and age group for 2013-2016 from surveillance hospital registers and monthly acute diarrhea outpatient visits reported to the Ministry of Health and Child Care during 2012-2016. Active surveillance data showed winter seasonal peaks in diarrhea- and rotavirus-related visits among children introduction; the percentage of rotavirus test-positive visits followed a similar seasonal pattern and decrease. Hospital register data showed similar pre-introduction seasonal variation and post-introduction declines in diarrhea hospitalizations among children 0-11 and 12-23 months of age. Monthly variation in outpatient diarrhea-related visits mirrored active surveillance data patterns. At 2 surveillance hospitals, the percentage of rotavirus-positive visits declined by 40% and 43% among children 0-11 months of age and by 21% and 33% among children 12-23 months of age in 2015 and 2016, respectively. Initial reductions in diarrheal illness among children introduction are encouraging. These early results provide evidence to support continued rotavirus vaccination and rotavirus surveillance in Zimbabwe.

The birth and survival of wildebeest calves.

This paper describes social organization, parturition, post partum behavior of wildebeest mothers and offspring, and calf predation during the annual birth peak in Ngorongoro Crater, Tanzania. The wildebeest's "follower-calf" system, unique among the Bovidae, is remarkably effective in protecting neonates. Even during hte one-month peak, the major predator on calves, the spotted hyena, is unable to feed to satiation. Calf survival is consistently high, despite large fluctuations in the numbers of wildebeest, with consequent effects on the size of the yearly calf crop.

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

2013-10-01

Full Text Available Probiotics are beneficial bacteria that colonize and replicate in the human intestinal tract providing a positive benefit to the host. Several clinical trials support the efficacy of certain probiotics in the prevention and treatment of various diarrheal illnesses. This paper reviews published clinical trials assessing the efficacy of various probiotic species and strains in preventing and treating acute diarrhea in children. The available evidence shows that few probiotic species (mostly Lactobacillus GG and Saccharomyces boulardii are efficacious in decreasing the duration and the severity of acute gastroenteritis, with the most prominent of the reported benefits, the reduction of the duration of diarrhea by approximately 1 day. With regard to the prevention of acute diarrhea in the community and the hospital, there is modest evidence that some probiotic species may be efficacious in preventing community acquired diarrhea (Bifidobacterium lactis, Lactobacillus reuteri, Lactobacillus GG, nosocomial acquired diarrhea (Lactobacillus GG and Clostridium difficile diarrhea (Lactobacillus GG and Saccharomyces boulardii. In conclusion, the available evidence suggests that probiotics are safe when used in healthy children and effective in reducing the duration of acute infectious diarrhea. Further studies are required to assess the efficacy of selected probiotic species and strains at different dosages for different clinical indications and patient groups.

Noroviruses (NoVs) are the leading cause of nonbacterial acute gastroenteritis worldwide in people of all ages. The P particle is a novel vaccine candidate derived from the protruding (P) domain of the NoV VP1 capsid protein. This study utilized the neonatal gnotobiotic pig model to evaluate the protective efficacies of primary infection, P particles, and virus-like particles (VLPs) against NoV infection and disease and the T cell responses to these treatments. Pigs either were vaccinated intranasally with GII.4/1997 NoV (VA387)-derived P particles or VLPs or were inoculated orally with a GII.4/2006b NoV variant. At postinoculation day (PID) 28, pigs either were euthanized or were challenged with the GII.4/2006b variant and monitored for diarrhea and virus shedding for 7 days. The T cell responses in intestinal and systemic lymphoid tissues were examined. Primary NoV infection provided 83% homologous protection against diarrhea and 49% homologous protection against virus shedding, while the P particle and VLP vaccines provided cross-variant protection (47% and 60%, respectively) against diarrhea. The protection rates against diarrhea are significantly inversely correlated with T cell expansion in the duodenum and are positively correlated with T cell expansion in the ileum and spleen. The P particle vaccine primed for stronger immune responses than VLPs, including significantly higher numbers of activated CD4+ T cells in all tissues, gamma interferon-producing (IFN-γ+) CD8+ T cells in the duodenum, regulatory T cells (Tregs) in the blood, and transforming growth factor β (TGF-β)-producing CD4+ CD25- FoxP3+ Tregs in the spleen postchallenge, indicating that P particles are more immunogenic than VLPs at the same dose. In conclusion, the P particle vaccine is a promising vaccine candidate worthy of further development. The norovirus (NoV) P particle is a vaccine candidate derived from the protruding (P) domain of the NoV VP1 capsid protein. P particles can be

Colestipol hydrochloride prophylaxis of diarrhea during pelvic radiotherapy

Stryker, J.A.; Chung, C.K.; Layser, J.D.

1983-01-01

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

Objective: To monitor the therapeutic impact of zinc supplementation on clinical course of acute diarrhea i.e. frequency of stool, on stool amount and duration of acute diarrhea. Study Design: Randomized controlled trial. Place and Duration of Study: Family medicine department, PAF Hospital, Islamabad Pakistan from Jul to Dec 2009. Material and Methods: One hundred and twenty eight children aged 6 months to 60 months in an Outpatient pediatric department of PAF Hospital, E-9 Sector Islamabad with acute diarrhea of less than 14 days were included in this randomized controlled trial. They were further divided into two groups zinc supplemented group (n=65) and non-zinc supplemented group (n=65). Results: Baseline characteristics were similar in both the groups. Mean age in zinc supplemented group was 33.67 +- 16.45 months and in non-zinc supplemented group 33.63 +- 16.44 months. Reduction in stool frequency per day was found 62 percent in zinc supplemented group and 26 percent reduction was found in non-zinc supplemented group with obvious difference of 36 percent between these two groups from day 3 to day 5, which was found statistically significant (p=0.01). Similarly, significant difference (p=0.01) was observed for reduction in amount of stool per day from day 3 and day 5 with obvious difference of 45 percent between the study groups. Conclusions: Oral zinc administration in acute diarrhea reduces the frequency of diarrhea, output of stool and decreases total duration of diarrhea. (author)

Due to limited laboratory facilities in the tropics, the exact role of enteric viruses in causing diarrhea among adults in the tropics is unknown. The purpose of this report is to describe a multicenter study undertaken in Djibouti to determine the prevalence of a large panel of enteric viruses using immunochromatography; antigenic detection by ELISA, RT-PCR cellular inoculation, sequence analysis; and indirect serology. Study samples were collected from 108 patients presenting acute and sporadic diarrhea. Although they are well known causes of diarrhea in children, rotavirus and adenovirus were identified in only 2 and 5% of adults respectively. In contrast human caliciviruses (HuCVs) and enterovirus were identified in 25 and 42% of adult cases respectively. Uncommon genotypes of HuCVs and recombinant forms (junction pol/l cap) as well as a significant number of sapovirus (30%) were identified. Further study is needed to clarify the role of enterovirus (echovirus) in the etiology of acute diarrhea in adults. No polivirus was identified. These new data from the Horn of Africa increase our knowledge about the epidemiology of acute infectious diarrhea that is a major public health problem and potential danger for travelers.

Childhood diarrhea remains a problem in countries like Nigeria where access to potable water, good hygiene and sanitation are lacking. Maternal education is an important determinant of health status of under-five children. Very few studies have investigated the relationship between maternal education and diarrhea in children in Nigeria. Therefore, this study was implemented to fill the gap. The study design was cross-sectional and 2013 National Survey was used. Children aged 0-24 months were investigated and the dependent variable was diarrhea status of the index child in the last two weeks prior the survey. The main independent variable was maternal education. Data were analyzed using Chi-square and Logistic regression models (α=0.05). Diarrhea prevalence was 13.7% and higher (15.5%) among children of women who have no formal education, and mothers living in the North East region of Nigeria experienced the highest prevalence (26.4%). Children whose mothers had no formal education were 2.69(CI= 1.800-4.015, p education. Maternal education is an important predictor of diarrhea among children aged 0-24 months in Nigeria. Policies to reduce diarrhea among children in Nigeria should target children of the illiterate, less educated mothers and those living in the North-West.

Dietary management of childhood diarrhea in low- and middle-income countries: a systematic review

Science.gov (United States)

2013-01-01

Background Current WHO guidelines on the management and treatment of diarrhea in children strongly recommend continued feeding alongside the administration of oral rehydration solution and zinc therapy, but there remains some debate regarding the optimal diet or dietary ingredients for feeding children with diarrhea. Methods We conducted a systematic search for all published randomized controlled trials evaluating food-based interventions among children under five years old with diarrhea in low- and middle-income countries. We classified 29 eligible studies into one or more comparisons: reduced versus regular lactose liquid feeds, lactose-free versus lactose-containing liquid feeds, lactose-free liquid feeds versus lactose-containing mixed diets, and commercial/specialized ingredients versus home-available ingredients. We used all available outcome data to conduct random-effects meta-analyses to estimate the average effect of each intervention on diarrhea duration, stool output, weight gain and treatment failure risk for studies on acute and persistent diarrhea separately. Results Evidence of low-to-moderate quality suggests that among children with acute diarrhea, diluting or fermenting lactose-containing liquid feeds does not affect any outcome when compared with an ordinary lactose-containing liquid feeds. In contrast, moderate quality evidence suggests that lactose-free liquid feeds reduce duration and the risk of treatment failure compared to lactose-containing liquid feeds in acute diarrhea. Only limited evidence of low quality was available to assess either of these two approaches in persistent diarrhea, or to assess lactose-free liquid feeds compared to lactose-containing mixed diets in either acute or persistent diarrhea. For commercially prepared or specialized ingredients compared to home-available ingredients, we found low-to-moderate quality evidence of no effect on any outcome in either acute or persistent diarrhea, though when we restricted these

Neonatal Hyperglycemia due to Transient Neonatal Diabetes Mellitus in Puerto Rico.

2015-01-01

Neonatal hyperglycemia is a metabolic disorder found in the neonatal intensive care units. Neonatal diabetes mellitus (NDM) is a very uncommon cause of hyperglycemia in the newborn, occurring in 1 in every 400,000 births. There are two subtypes of neonatal diabetes mellitus: permanent neonatal diabetes mellitus (PNDM) and transient neonatal diabetes mellitus (TNDM). We describe a term, small for gestational age, female neonate with transient neonatal diabetes mellitus who presented with poor feeding tolerance and vomiting associated with hyperglycemia (385 mg/dL), glycosuria, and metabolic acidosis within the first 12 hours of life. The neonate was treated with intravenous insulin, obtaining a slight control of hyperglycemia. An adequate glycemia was achieved at 5 weeks of life. The molecular studies showed complete loss of maternal methylation at the TND differentially methylated region on chromosome 6q24. The etiology of this neonate's hyperglycemia was a hypomethylation of the maternal TND locus. A rare cause of neonatal diabetes mellitus must be considered if a neonate presents refractory hyperglycemia. To our knowledge, this is the first case reported in Puerto Rico of transient neonatal mellitus due to the uncommon mechanism of maternal hypomethylation of the TND locus. Its prevalence in Puerto Rico is unknown.

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

Seven beagles in a colony of dogs had chronic diarrhea for at least 30 days. The dogs were subsequently treated with tylosin 20 mg/kg BW q24h PO for 10 days. During the treatment period, the feces became firmer but remained loose. When the treatment was discontinued, the diarrhea reappeared in 3 weeks. The feces remained abnormally loose in all dogs treated with metronidazole, trimethoprim-sulfadiazine, or doxycycline and prednisone. The diet was then changed for 10 days from a highly digestible moist pet food to a dry food developed for normal adult dogs. The feces again became firmer, although still loose in some dogs. The period was then extended to 3 month, but the fecal consistency continued to fluctuate from ideal to diarrhea. The dogs were treated a 2nd time with tylosin 20 mg/kg BW q24h PO for 10 days. The feces then became significantly firmer and remained so throughout a 3-month follow-up. We conclude that the combination of diet and tylosin was more effective than either agent alone in control of chronic diarrhea.

Dupont, Christophe; Foo, Jimmy Lee Kok; Garnier, Philippe; Moore, Nicholas; Mathiex-Fortunet, Hèlène; Salazar-Lindo, Eduardo

2009-04-01

Diosmectite is a clay used to treat children with acute watery diarrhea. However, its effects on stool output reduction, the key outcome for pediatric antidiarrheal drugs, have not been shown. Two parallel, double-blind studies of diosmectite efficacy on stool reduction were conducted in children 1 to 36 months old in Peru (n = 300) and Malaysia (n = 302). Inclusion criteria included 3 or more watery stools per day for less than 72 hours and weight/height ratios of 0.8 or greater. Exclusion criteria were the need for intravenous rehydration, gross blood in stools, fever higher than 39 degrees C, or current treatment with antidiarrheal or antibiotic medications. Rotavirus status was determined. Diosmectite dosage was 6 g/day (children 1-12 months old) or 12 g/day (children 13-36 months old), given for at least 3 days, followed by half doses until complete recovery. Patients were assigned randomly to groups given diosmectite or placebo, in addition to oral rehydration solution (World Health Organization). Children in each study had comparable average ages and weights. The frequencies of rotavirus infection were 22% in Peru and 12% in Malaysia. Similar amounts of oral rehydration solution were given to children in the diosmectite and placebo groups. Stool output was decreased significantly by diosmectite in both studies, especially among rotavirus-positive children. In pooled data, children had a mean stool output of 94.5 +/- 74.4 g/kg of body weight in the diosmectite group versus 104.1 +/- 94.2 g/kg in the placebo group (P = .002). Diarrhea duration was reduced by diosmectite, which was well tolerated. These results show that diosmectite significantly decreased stool output in children with acute watery diarrhea, especially those who were rotavirus-positive.

2017-06-01

Craniofacial duplication abnormity is a rare phenomenon in buiatric practice. This report attends to a male German Holstein calf which could be classified as a diprosopic iniodymus. A fetus exhibiting a doubled face was delivered after fetotomy. To our knowledge, this is the first description of diprosopiasis with two cranial cavities as well as two separate encephala in a calf showing the potential extent of duplication. Throughout this work also the question is answered of whether this malformation in a bovine species arose from one embryo or rather, there is a dizygotic background by genotyping of tissue samples from both parts of the diprosopus. Regarding etiology, not only hereditary dispositions including among others a failed function of the signaling molecule Sonic hedgehog mediating regulation of craniofacial morphogenesis, but also incompletely separated monozygotic twins are discussed.

Acute treatment-related diarrhea during postoperative adjuvant therapy for high-risk rectal carcinoma

International Nuclear Information System (INIS)

Miller, Robert C.; Martenson, James A.; Sargent, Daniel J.; Kahn, Michael J.; Krook, James E.

1998-01-01

Purpose: The combination of pelvic radiotherapy and 5-fluorouracil-based chemotherapy is associated with an increase in acute gastrointestinal toxicity during rectal adjuvant therapy, most notably an increased incidence of diarrhea. Previous randomized, prospective studies have limited their analysis to presenting rates of severe and life-threatening diarrhea (Grade 3 or greater), and few data are available detailing the extent of mild to moderate diarrhea. To provide baseline data for future studies, we conducted a detailed analysis of diarrhea from a prior clinical trial of adjuvant therapy for rectal cancer. Methods and Materials: In a multiinstitutional clinical trial, 204 eligible patients with rectal carcinoma that either was deeply invasive (T3-T4) or involved regional lymph nodes were randomized to receive either postoperative pelvic radiotherapy alone (45 to 50.4 Gy) or pelvic radiotherapy and bolus 5-fluorouracil-based chemotherapy. Toxicity was assessed prospectively. Results: For the 99 eligible patients who received pelvic radiotherapy alone, rates of Grades 0, 1, 2, 3, and 4 diarrhea during treatment were 59, 20, 17, 4, and 0%, respectively. For the 96 eligible patients who received radiotherapy and 5-fluorouracil, the overall rates of grades 0, 1, 2, 3, and 4 diarrhea were 21, 34, 23, 20, and 2%, respectively. The increased rates of diarrhea during adjuvant rectal therapy were manifested across all toxicity levels for patients receiving chemotherapy and pelvic radiotherapy. Of primary clinical importance is the substantial increase in severe or life-threatening diarrhea (Grade 3 or more) (22 vs. 4%, p = 0.001) Additionally, increased rates of any diarrhea and also severe or life-threatening diarrhea were observed in patients who had a low anterior resection compared with those who had an abdominoperineal resection (p < 0.001 and p = 0.006, respectively). Conclusion: These results will be of value as a baseline for investigators who want to use

Full Text Available Neonatal hyperglycemia is a metabolic disorder found in the neonatal intensive care units. Neonatal diabetes mellitus (NDM is a very uncommon cause of hyperglycemia in the newborn, occurring in 1 in every 400,000 births. There are two subtypes of neonatal diabetes mellitus: permanent neonatal diabetes mellitus (PNDM and transient neonatal diabetes mellitus (TNDM. We describe a term, small for gestational age, female neonate with transient neonatal diabetes mellitus who presented with poor feeding tolerance and vomiting associated with hyperglycemia (385 mg/dL, glycosuria, and metabolic acidosis within the first 12 hours of life. The neonate was treated with intravenous insulin, obtaining a slight control of hyperglycemia. An adequate glycemia was achieved at 5 weeks of life. The molecular studies showed complete loss of maternal methylation at the TND differentially methylated region on chromosome 6q24. The etiology of this neonate’s hyperglycemia was a hypomethylation of the maternal TND locus. A rare cause of neonatal diabetes mellitus must be considered if a neonate presents refractory hyperglycemia. To our knowledge, this is the first case reported in Puerto Rico of transient neonatal mellitus due to the uncommon mechanism of maternal hypomethylation of the TND locus. Its prevalence in Puerto Rico is unknown.

Despite growth in the number of cruises worldwide, evidence about diarrhea experienced by cruise ship passengers remains sparse. We investigated rates of diarrhea and related factors among passengers on world cruises departing from Japan. Targeting passengers on five world cruises (n = 4180) from 2012 to 2013 (85-103 travel days), we calculated rates of health seeking behavior for diarrhea by sex, age group, and number of roommates for each cruise. We estimated rate ratios and 95% confidence intervals, using the group aged 20-39 years, women, and 2-4 roommates as referent categories. We found 5.04-6.00 cases per 10,000 person-days in the five cruises, with an elevated number after calling at ports. Older passengers (>60 years) and passengers with fewer roommates had an elevated risk of health seeking behavior for diarrhea, although passengers aged 60 years and without roommates. Older passengers and passengers with fewer roommates may be more likely to seek medical treatment for diarrhea during travel on a world cruise, and should take preventive measures. Copyright © 2018.

2010-01-01

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

Prescription of an appropriate dialysis target weight (dry weight) requires accurate evaluation of the degree of hydration. The aim of this study was to investigate whether a state of normal hydration (DW(cBIS)) as defined by calf bioimpedance spectroscopy (cBIS) and conventional whole body bioimpedance spectroscopy (wBIS) could be characterized in hemodialysis (HD) patients and normal subjects (NS). wBIS and cBIS were performed in 62 NS (33 m/29 f) and 30 HD patients (16 m/14 f) pre- and post-dialysis treatments to measure extracellular resistance and fluid volume (ECV) by the whole body and calf bioimpedance methods. Normalized calf resistivity (ρ(N)(,5)) was defined as resistivity at 5 kHz divided by the body mass index. The ratio of wECV to total body water (wECV/TBW) was calculated. Measurements were made at baseline (BL) and at DW(cBIS) following the progressive reduction of post-HD weight over successive dialysis treatments until the curve of calf extracellular resistance is flattened (stabilization) and the ρ(N)(,5) was in the range of NS. Blood pressures were measured pre- and post-HD treatment. ρ(N)(,5) in males and females differed significantly in NS. In patients, ρ(N)(,5) notably increased with progressive decrease in body weight, and systolic blood pressure significantly decreased pre- and post-HD between BL and DW(cBIS) respectively. Although wECV/TBW decreased between BL and DW(cBIS), the percentage of change in wECV/TBW was significantly less than that in ρ(N)(,5) (-5.21 ± 3.2% versus 28 ± 27%, p hydration between BL and DW(cBIS).

Full Text Available This qualitative research aimed at identifying the knowledge of the mothers regarding diarrhea. It was conducted with eight mothers of hospitalized children in a university hospital located in Santa Cruz, Rio Grande do Norte, Brazil, in 2012. Data were collected through open interviews and the analysis was based on Bardin. The categories emerging from the analysis were: understanding diarrhea and preventing/treating diarrhea. Regarding the understanding of diarrhea, mothers conceptualize and understand it from the symptoms, habits/eating mistakes and/or cultural beliefs. Concerning the prevention and treatment of the disease, the mothers highlight hygiene and home cleaning as preventive measures, as well the importance of home and hospital care measures. The interviewees have basic knowledge of pathology, further studies are necessary in order to define the current gap between the knowledge of mothers and recurrence of diarrhea cases, resulting in hospitalization and expenses with unnecessary treatment.

Full Text Available Introduction: Diarrhea is a leading cause of mortality in children in developing countries and the condition is worse in slums. In order to provide effective preventive and management strategies, it is important to identify factors associated with the disease. This study was carried out to investigate the risk factors of diarrhea in  children under five years of age in urban slums. Methods: Parents of all children under five years from the urban slums of Tansen municipality, Palpa, Nepal were interviewed using a standardized pretested questionnaire and proforma. Parental variables, environmental factors, and presence of diarrhea in those children in past three months were collected by trained enumerators and the data were analyzed with statistical software SPSS-10. Results: A total of 450 under five years children were enrolled in the study. There were 216 (48% male and 234 (52% female children with F:M ratio of 1.08:1. Occurrence of diarrhea was lower if the children were breast-fed for more than six months, well-nourished, used fountain water for drinking, or used boiled or treated water. Similarly, diarrhea prevalence was lower if father had a regular job, daily income in the family was more than one US dollar, there was a toilet in the house, practice of hand washing was followed before feeding or preparing food, or there was no child suffering from diarrhea in the neighborhood. Conclusion: There are a few variables that are significantly related to diarrhea in children under five years of age. In order to decrease the diarrheal episodes in children in the slums of the developing countries, priority could be given in the improvement of those variables.

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

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

Full Text Available Results of observation of children from 2,5 months to 4 years old, treated in hospital with diagnosis chronic diarrhea are analyzed in this article. Diarrhea debuted in first year of living in most cases. The reason of onset of diarrhea often was alimentary factor. Hereditary predisposition, pathologic pregnancy, and diseases in women at the time of pregnancy played an important role in development of disease. Nutrition of children in early age was characterized by low duration of breast feeding and early conversion of children to the mixed and artificial feeding. Main food stuffs in children's nutrition on mixed and artificial feeding was adapted milk formulas, and rarely non adapted milk food (cow's and goat's milk, kefir. Only 30% of mothers had a definite knowledge of proper child's feeding and advantages of breast feeding. This fact indicates necessity of more active educational work by medical staff.Key words: children, chronic diarrhea, nutrition.

Mitochondria are essential for energy production in the muscle cell and for this they are dependent upon a sufficient supply of oxygen by the circulation. Exercise training has shown to be a potent stimulus for physiological adaptations and mitochondria play a central role. Whether changes in mitochondrial respiration are seen after exercise in patients with a reduced circulation is unknown. The aim of the study was to evaluate the time course and whether one session of calf raise exercise stimulates mitochondrial respiration in the calf muscle of patients with peripheral vascular disease. One group of patients with peripheral vascular disease (n = 11) and one group of healthy older adults (n = 11) were included. Patients performed one session of continuous calf raises followed by 5 extra repetitions after initiation of pain. Healthy older adults performed 100 continuous calf raises. Gastrocnemius muscle biopsies were collected at baseline and 15 minutes, one hour, three hours and 24 hours after one session of calf raise exercise. A multi substrate (octanoylcarnitine, malate, adp, glutamate, succinate, FCCP, rotenone) approach was used to analyze mitochondrial respiration in permeabilized fibers. Mixed-linear model for repeated measures was used for statistical analyses. Patients with peripheral vascular disease have a lower baseline respiration supported by complex I and they increase respiration supported by complex II at one hour post-exercise. Healthy older adults increase respiration supported by electron transfer flavoprotein and complex I at one hour and 24 hours post-exercise. Our results indicate a shift towards mitochondrial respiration supported by complex II as being a pathophysiological component of peripheral vascular disease. Furthermore exercise stimulates mitochondrial respiration already after one session of calf raise exercise in patients with peripheral vascular disease and healthy older adults.

The effectiveness of the calf-squeeze technique during aspiration thrombectomy using guiding catheter in the treatment of an acute lower extremity deep vein thrombosis (DVT) was evaluated by the use of imaging and the clinical follow-up of patients. A prospective analysis of ten patients (seven women, three men; median age, 56.9 years) with common iliac vein (CIV) obstruction and ipsilateral DVT was performed for this study. All patients presented with leg edema or pain and were treated with catheter-directed thrombolysis via an ipsilateral popliteal vein approach after insertion of a temporary inferior vena cava (IVC) filter. Subsequently, the patients were treated with by aspiration thrombectomy using a guiding catheter to remove the residual thrombus. The calf-squeeze technique during aspiration thrombectomy can be used to induce the proximal migration of thrombi in the popliteal, tibial, and muscular veins were used to increase venous flow. The calf-squeeze technique was employed at mean of 1.3 times (range, 1-3 times). All patients showed proximal migration of a popliteal and muscular vein thrombus during the execution of the calf-squeeze technique. Successful recanalization was achieved in all patients (100%) without any complications. On duplex ultrasonography, which was performed immediately after the aspiration thrombectomy, four patients had a residual thrombus in the soleal muscular veins. However, none of the patients had a thrombus in the popliteal and tibial veins; and, during follow-up, no DVT recurred in any patient. The use of the calf-squeeze technique during aspiration thrombectomy after catheter-directed thrombolysis can induce the proximal migration of thrombi in the popliotibial and muscular veins and is an effective method that can remove a thrombus in calf veins.

Full Text Available Cluster differentiation 4 (CD4 count estimation, which is not readily available in most resource poor settings in Nigeria, is an important indexdetermining commencement of antiretroviral therapy (ART. It is imperative for physicians who come in contact with these patients in such settings to recognize other parameters to evaluate these patients. The clinical correlates of diarrhea and gut parasites among human immunodeficiency virus (HIV-seropositive patients attending our special treatment clinic were studied. Three hundred and forty consenting HIV-positive adult subjects were enrolled. Their stool and blood specimens were collected for a period of three months. Stool samples were analyzed for the presence of diarrhea and gut parasites. The patients were clinically evaluated by physical examination for the presence of pallor, dehydration, oral thrush, wasting lymphadenopathy, dermatitis, skin hyperpigmentation, and finger clubbing. Participants with diarrhea represented 14.1% of the population, while 21.5% harbored one or more parasites. In the subjects with diarrhea, 14.6% harbored gut parasites. The presence of diarrhea was associated with a low CD4 count. Clinically, oral thrush, wasting, and rashes were more reliable predictors of low CD4 count levels; whereas, the presence of pallor, dehydration, wasting, and rashes correlated with the presence of diarrhea. HIV patients presenting with pallor, dehydration, wasting, and rashes should be evaluated for the presence of diarrhea. The clinical variables associated with low CD4 count in this study may guide commencing antiretroviral therapy in resource poor settings.

Aim: The aim of this study is to assess the sensitivity and specificity of procalcitonin to determine bacterial etiology of diarrhea. The examinees and methods: For this purpose we conducted the study comprising 115 children aged 1 to 60 months admitted at the Department of Pediatric Gastroenterology, Pediatric Clinic, divided in three groups based on etiology of the diarrhea that has been confirmed with respective tests during the hospitalization. Each group has equal number of patients – 35. The first group was confirmed to have bacterial diarrhea, the second viral diarrhea and the third extra intestinal diarrhea. The determination of procalcitonin has been established with the ELFA methods of producer B.R.A.H.M.S Diagnostica GmbH, Berlin, (Germany). Results: From the total number of 1130 patient with acute diarrhea procalcitonin was assessed in 105. 67 (63.8%) of these patient were male. More than one third (38.14%) of the children in our study were younger then 12 months. Approximately the same was the number of children 13-24 months (33 patients or 31.43%) and 25-60 months (32 patients or 30.43%). The mean value of PRC in children with viral diarrhea was 0.13±0.5 ng/mL in children with bacterial diarrhea was 5.3±4.9 ng/m Land in children with extra intestinal diarrhea was 1.7±2.8 ng/mL. When measured using ANOVA and Turkey HSD tests, results have shown the statistical significance when comparing viral with bacterial and extra intestinal diarrhea but were statistically insignificant when comparing bacterial and extra intestinal diarrhea. Conclusion: Procalcitonin is an important but not conclusive marker of bacterial etiology of acute diarrhea in children younger than 5 years. PMID:24944526

The cause of severe diarrhea in patients with systemic amyloidosis is obscure. We therefore performed pathophysiological studies in three such patients in an effort to determine the mechanism of amyloid diarrhea. Epithelial cell absorption rate of electrolytes was measured during steady state GI perfusion of a saline-mannitol solution. GI transit time of PEG and absorption of radiolabeled bile acid were measured simultaneously while subjects ingested three meals per day. To obtain a diarrhea control group for transit time and bile acid absorption, normal subjects were studied when they had diarrhea caused by ingestion of Milk of Magnesia (MOM). Diarrhea could not be explained by malabsorption of ingested nutrients, bacterial overgrowth, bile acid malabsorption, or epithelial cell malabsorption of electrolytes. However, 25% of polyethylene glycol (PEG) ingested with a standard meal was recovered in stool in 45 min, which is 10 times faster than in normal subjects with equally severe diarrhea caused by ingestion of MOM. All of the patients had autonomic neuropathy that remained unrecognized for 15-36 months after onset of chronic diarrhea; it seems likely that this was the cause of rapid transit. Severe chronic diarrhea in three patients with systemic amyloidosis was mediated by extremely rapid transit of chyme and digestive secretions through the intestine.

Full Text Available ABSTRACT OBJECTIVE To analyze the contributions of the socioeconomic, hygienic, and sanitation improvements in reducing the prevalence of diarrhea in a city of the Amazon. METHODS In this population-based cross-sectional study, we analyzed data from surveys conducted in the city of Jordão, Acre. In 2005 and 2012, these surveys evaluated, respectively, 466 and 826 children under five years old. Questionnaires were applied on the socioeconomic conditions, construction of houses, food and hygienic habits, and environmental sanitation. We applied Pearson’s Chi-squared test and Poisson regression to verify the relationship between origin of water, construction of homes, age of introduction of cow’s milk in the diet, place of birth and the prevalence of diarrhea. RESULTS The prevalence of diarrhea was reduced from 45.1% to 35.4%. We identified higher probability of diarrhea in children who did not use water from the public network, in those receiving cow’s milk in the first month after birth, and in those living in houses made of paxiúba. Children born at home presented lower risk of diarrhea when compared to those who were born in hospital, with this difference reversing for the 2012 survey. CONCLUSIONS Sanitation conditions improved with the increase of bathrooms with toilets, implementation of the Programa de Saúde da Família (PSF – Family Health Program, and water treatment in the city. The multivariate regression model identified a statistically significant association between use of water from the public network, construction of houses, late introduction of cow’s milk, and access to health service with occurrence of diarrhea.

Hiraga, T.; Abe, M.; Iwasa, K.; Takehana, K.; Tetsuka, M.

1989-01-01

A male Holstein-Friesian calf with seven legs was examined macroscopically and radiographically. External features included two normal forelimbs, two normal hindlimbs (lateral hindlimbs), and two abnormal hindlimbs (medial hindlimbs) which were underdeveloped. Also, a rudimentary forelimb, which was attached to the pelvic region, was observed between both the medial hindlimbs. It consisted of an underdeveloped humerus, a duplicated ulna, several carpal bones, a partially duplicated metacarpal bone and three digits with three hoofs. This leg was connected with two sets of coxae by a irregular-shaped bone considered the vestigial vertebrae and ribs. Two penises and scrotums, three kidneys and testes were also observed. This calf is the first case of dipygus associated with pygopagus parasiticus in cattle. Based on these findings, the pathogenesis of this rare anomaly was briefly discussed from an embryological point of view

Possible death of a buffalo calf (Syncercus caffer due to suspected heartwater (Ehrlichia ruminantium : clinical communication

2004-06-01

Full Text Available Rickettsial organisms resembling Ehrlichia ruminantium (the causative organism of heartwater were demonstrated in brain smears and formalin-fixed brain sections derived from a buffalo calf that died on a private game reserve in northern KwaZulu-Natal. The possibility that the tick-free environment of a quarantine boma may have affected the calf 's immunity, is discussed. These findings suggest that monitoring heartwater in wild ruminants and making brain smears as a routine during post mortem evaluations of wild ruminants, should be encouraged.

The neonatal brain

The clinical examination of the CNS in the neonate is often difficult in cases of complex pathology. Diagnostic imaging of the neonatal brain has become extremely useful and in the last decade has developed in two main directions: CT and US. MR imaging has been used recently with varying success in the diagnosis of pathology in the neonatal brain. Despite technical difficulties, this imaging method is likely to become increasingly important in the neonate. The paper examines the normal neonatal brain anatomy as seen with the different modalities, followed by pathologic conditions. Attention is directed to the common pathology, in asphyxiated newborns, the patholphysiology of intraventicular hemorrhage and periventricular leukomalacia in the preterm neonate, and hypoxic-ischemic brain injury in the term neonate. Pitfalls, artifacts, and problems in image interpretation are illustrated. Finally, the subsequent appearance of neonatal pathology later in infancy and childhood is discussed

Mature Simmental × Angus cows (214 cows; 635 ± 7 kg) were utilized to determine the effects of late gestation and early postpartum supplementation of methionine hydroxy analog (MHA) on cow BW, BCS, milk production, milk composition, reproduction, and calf performance until weaning in a fall-calving, cool-season grazing system. Cows were stratified by BW, age, AI sire, and assigned to 1 of 12 pastures (17 or 18 cows·pasture). Pastures were randomly allotted to 1 of 2 treatments: control (0.45 kg·cow·d of wheat midd-based pellets, = 6) or supplement including MHA (0.45 kg·cow·d of wheat midd-based pellets including 10 g MHA supplied as MFP (Novus International, Inc., St. Charles, MO; = 6). Treatments were fed 23 ± 7 d prepartum through 73 ± 7 d postpartum. Cow BW was collected at postcalving (27 ± 7 d postpartum), end of supplementation (73 ± 7 d postpartum), AI, pregnancy check, and end of trial (192 and 193 ± 7 d postpartum). At 73 ± 7 d postpartum, a subset of cow-calf pairs was used in a weigh-suckle-weigh procedure to determine milk production, and milk samples were taken to determine milk composition ( = 45·treatment). Serum from blood was collected at 73 ± 7 and 83 ± 7 d postpartum to determine cow cyclicity and concentrations of 2-hydroxy4-(methylthio) butanoic acid (HMTBa) and L-Methionine. After supplementation, all cow-calf pairs were managed as a common group until weaning (193 ± 7 d of age). Cows were bred via AI at 97 ± 7 d postpartum and clean-up bulls were turned out 11 d post-AI for a 55-d breeding season. Cows fed MHA had greater ( Cow BW and BCS were not different ( ≥ 0.10) at any time points between treatments. There was no treatment effect ( ≥ 0.17) on calf birth BW, calf weaning BW (193 ± 7 d of age), or calf ADG. Calculated 24-h milk production, milk composition and component production did not differ ( ≥ 0.21). There were no differences ( ≥ 0.50) in percentage of cows cycling, AI conception rate, and overall

Neonatal hypertension (HT) is a frequently under reported condition and is seen uncommonly in the intensive care unit. Neonatal HT has defined arbitrarily as blood pressure more than 2 standard deviations above the base as per the age or defined as systolic BP more than 95% for infants of similar size, gestational age and postnatal age. It has been diagnosed long back but still is the least studied field in neonatology. There is still lack of universally accepted normotensive data for neonates as per gestational age, weight and post-natal age. Neonatal HT is an important morbidity that needs timely detection and appropriate management, as it can lead to devastating short-term effect on various organs and also poor long-term adverse outcomes. There is no consensus yet about the treatment guidelines and majority of treatment protocols are based on the expert opinion. Neonate with HT should be evaluated in detail starting from antenatal, perinatal, post-natal history, and drug intake by neonate and mother. This review article covers multiple aspects of neonatal hypertension like definition, normotensive data, various etiologies and methods of BP measurement, clinical features, diagnosis and management.

1986-01-01

An anthropological study of knowledge, attitudes and practices relating to child diarrhea and specifically to ORS was carried out in Bangladesh. The purpose of the study was to help design a culturally-sensitive social marketing program. Information was gathered on indigenous classification of diarrheas, patterns of therapy recourse and diarrhea management, and understanding of dehydration symptoms as well as use and attitudes regarding ORS. Among the findings were that 58% of households sampled had tried ORS at least once; ORS was perceived as a medicine with several positive attributes; literacy was positively related to ORS use; and there were no significant cultural barriers to ORS adoption.

The purpose of these studies was to gain insight into the pathophysiology of pure osmotic diarrhea and the osmotic diarrhea caused by carbohydrate malabsorption. Diarrhea was induced in normal volunteers by ingestion of polyethylene glycol (PEG), which is nonabsorbable, not metabolized by colonic bacteria, and carries no electrical charge. In PEG-induced diarrhea, (a) stool weight was directly correlated with the total mass of PEG ingested; (b) PEG contributed 40-60% of the osmolality of the ...

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

Schiller, L.R.; Bilhartz, L.E.; Santa Ana, C.A.

1990-01-01

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

A divergent rotavirus I was detected using viral metagenomics in the feces of a cat with diarrhea. The eleven segments of rotavirus I strain Felis catus encoded non-structural and structural proteins with amino acid identities ranging from 25 to 79% to the only two currently sequenced members of that viral species both derived from canine feces. No other eukaryotic viral sequences nor bacterial and protozoan pathogens were detected in this fecal sample suggesting the involvement of rotavirus I in feline diarrhea.

Full Text Available Background: Jaundice is a common condition among neonates. Prolonged unconjugated hyperbilirubinemia occurs when jaundice persists beyond two weeks in term neonates and three weeks in preterm neonates. This study aimed to determine the etiologies of prolonged unconjugated hyperbilirubinemia in infants admitted to the neonatal ward of Besat Hospital in Hamadan, Iran. Methods: This study was conducted on all infants diagnosed with prolonged unconjugated hyperbilirubinemia during 2007-2012 in the neonatal ward of Besat Hospital in Hamadan, Iran. Demographic characteristics of infants, physical examination and laboratory findings were collected and analyzed to determine the etiologies of neonatal hyperbilirubinemia. Results: In total, 100 infants diagnosed with neonatal hyperbilirubinemia were enrolled in this study, including 49 male and 51 female neonates with mean age of 20±1 days and mean bilirubin level of 17.5±4.0 mg/dL. Main causes of hyperbilirubinemia were urinary tract infection, ABO incompatibility, hypothyroidism and glucose-6-phosphate dehydrogenase deficiency in 14%, 5%, 6% and 5% of neonates, respectively. Moreover, unknown etiologies, such as breastfeeding, were detected in 70% of the studied infants. Conclusion: According to the results of this study, determining the main causes of prolonged unconjugated hyperbilirubinemia in neonates is of paramount importance. In the majority of cases, neonatal hyperbilirubinemia is associated with physiological factors, such as breastfeeding.

Full Text Available Hypospadias is a congenital problem reported in dogs, sheep and goats and occurrence of this anomaly in calves is rare. In fact, hypospadias is congenital absence of the urethra. In October 2015, a client attended the veterinary clinic for treatment of a 2 month old calf. Physical examination was performed following anamnesis. Vital signs including heart and respiratory rates, body temperature and peristaltic movements of the gastrointestinal system were normal. Examination of the urinary system revealed aplasia of the urethra at the perineum from beneath the rectum to the end of the penis and the calf was diagnosed with hypospadias. Physical examination also revealed the presence of an umbilical hernia with diameter of 6 cm and cryptorchidism. After diagnosis, the defect was corrected by surgical method to alleviate its side effects. Six months after surgical correction, the calf had satisfactory growth rate.

Sizakele L.T. Khoza

2014-11-01

Full Text Available Background: Neonatal pain management has received increasing attention over the past four decades. Research into the effects of neonatal pain emphasises the professional, ethical and moral obligations of staff to manage pain for positive patient outcomes. However, evaluation studies continuously report evidence of inadequate neonate pain management and a gap between theory and practice. Objective: This study reviewed current practice in neonatal pain management to describe the knowledge, attitudes and practices of nurses and doctors regarding pain management for neonates in two academic hospitals. Method: A non-experimental, prospective quantitative survey, the modified Infant Pain Questionnaire, was used to collect data from 150 nurses and doctors working in the neonatal wards of two academic hospitals in central Gauteng. Results: The response rate was 35.33% (n = 53, most respondents being professional nurses (88.68%; n = 47 working in neonatal intensive care units (80.77%; n = 42; 24 (45.28% had less than 5 years’ and 29 respondents 6 or more years’ working experience in neonatal care. A review of pain management in the study setting indicated a preference for pharmacological interventions to relieve moderate to severe pain. An association (p < 0.05 was found between pain ratings on 5 procedures and frequency of administration of pharmacological pain management. Two-thirds of respondents (64% reported that there were no pain management guidelines in the neonatal wards in which they worked. Conclusion: The interventions to manage moderate neonatal pain are in line with international guidelines. However, neonatal pain management may not occur systematically based on prior assessment of neonatal pain, choice of most appropriate intervention and evaluation. This study recommends implementation of a guideline to standardise practice and ensure consistent and adequate pain management in neonates.

Therapeutic Targeting of CPT-11 Induced Diarrhea: A Case for Prophylaxis

Science.gov (United States)

Swami, Umang; Goel, Sanjay; Mani, Sridhar

2014-01-01

CPT-11 (irinotecan), a DNA topoisomerase I inhibitor is one of the main treatments for colorectal cancer. The main dose limiting toxicities are neutropenia and late onset diarrhea. Though neutropenia is manageable, CPT-11 induced diarrhea is frequently severe, resulting in hospitalizations, dose reductions or omissions leading to ineffective treatment administration. Many potential agents have been tested in preclinical and clinical studies to prevent or ameliorate CPT-11 induced late onset diarrhea. It is predicted that prophylaxis of CPT-11 induced diarrhea will reduce sub-therapeutic dosing as well as hospitalizations and will eventually lead to dose escalations resulting in better response rates. This article reviews various experimental agents and strategies employed to prevent this debilitating toxicity. Covered topics include schedule/dose modification, intestinal alkalization, structural/chemical modification, genetic testing, anti-diarrheal therapies, transporter (ABCB1, ABCC2, BCRP2) inhibitors, enzyme (β-glucuronidase, UGT1A1, CYP3A4, carboxylesterase, COX-2) inducers and inhibitors, probiotics, antibiotics, adsorbing agents, cytokine and growth factor activators and inhibitors and other miscellaneous agents.

Prevention of deep vein thrombosis after total knee arthroplasty. Coumadin versus pneumatic calf compression.

Science.gov (United States)

Hodge, W A

1991-10-01

The rate of deep vein thrombosis (DVT) after total knee arthroplasty (TKA) without prophylaxis has been reported as high as 84%. Coumadin anticoagulation and pneumatic calf compression (PCC) boots are two current therapies that have been thought to be effective in reducing this high rate of DVT. To investigate these two methods, a nonrandomized prospective study was designed. The first group involved treating 48 consecutive knee arthroplasties with a regimen of coumadin anticoagulation. The second group involved 81 consecutive knee arthroplasties treated with sequential PCC boots. Bilateral lower extremity venography was performed between the eighth and tenth hospital postoperative days. The overall incidence of DVT in the coumadin group was 33%, with 29% having calf thrombi and 6% having thigh thrombi. The overall incidence of DVT in the boot group was 31%, with 27% having calf thrombi and 6% having thigh thrombi. In both groups, there were no treatment-related complications. Cost analysis of the administration of each type of therapy showed coumadin to be approximately 50% more expensive than PCC boots. Although coumadin and PCC boot therapy are safe and effective in reducing the incidence of DVT after TKA, there are economic factors that make the latter a more favorable option.

Interpretation of peripheral circulation in ill neonates is crucial but difficult. The aim was to analyse parameters potentially influencing peripheral oxygenation and circulation. In a prospective observational cohort study in 116 cardio-circulatory stable neonates, peripheral muscle near-infrared spectroscopy (NIRS) with venous occlusion was performed. Tissue oxygenation index (TOI), mixed venous oxygenation (SvO(2)), fractional oxygen extraction (FOE), fractional tissue oxygen extraction (FTOE), haemoglobin flow (Hbflow), oxygen delivery (DO(2)), oxygen consumption (VO(2)), and vascular resistance (VR) were assessed. Correlation coefficients between NIRS parameters and demographic parameters (gestational age, birth weight, age, actual weight, diameter of calf, subcutaneous adipose tissue), monitoring parameters (heart rate, arterial oxygen saturation (SaO(2)), mean blood pressure (MAP), core/peripheral temperature, central/peripheral capillary refill time) and laboratory parameters (haemoglobin concentration (Hb-blood), pCO(2)) were calculated. All demographic parameters except for Hbflow and DO(2) correlated with NIRS parameters. Heart rate correlated with TOI, SvO(2), VO(2) and VR. SaO(2) correlated with FOE/FTOE. MAP correlated with Hbflow, DO(2), VO(2) and VR. Core temperature correlated with FTOE. Peripheral temperature correlated with all NIRS parameters except VO(2). Hb-blood correlated with FOE and VR. pCO(2) levels correlated with TOI and SvO(2). The presence of multiple interdependent factors associated with peripheral oxygenation and circulation highlights the difficulty in interpreting NIRS data. Nevertheless, these findings have to be taken into account when analysing peripheral oxygenation and circulation data.

Muscle enlargement and hypertrophy are rare findings in neurogenic lesions. The two in combination have been reported in cases of peripheral nerve lesions, polyneuropathy, and poliomyelitis. True and pseudo muscle hypertrophy are the two possible etiologies, whereas infiltration, stretch, or exercise of the muscle are the causative factors. We report two cases of unilateral calf enlargement, one occurring after surgery for S1 radiculopathy with associated cramping, and the other after poliomyelitis.

Solanum paniculatum root extract reduces diarrhea in rats

Jonh A.B. Tenório

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

Congenital chloride diarrhea (CCD) is a rare autosomal recessive disease which is characterized by intractable diarrhea of infancy, failure to thrive, high fecal chloride, hypochloremia, hypokalemia, hyponatremia and metabolic alkalosis. In this case report, we present the first female and the second official case of CCD in Iran. A 15-month-old girl referred to our hospital due to failure to thrive and poor feeding. She had normal kidneys, liver and spleen. Treating her with Shohl's solution, thiazide and zinc sulfate did not result in weight gain. Consequently, pseudo-Bartter syndrome was suspected, she was treated with intravenous (IV) therapy to which she responded dramatically. In addition, hypokalemia resolved quickly. Since this does not usually happen in patients with the pseudo-Bartter syndrome, stool tests were performed. Abnormal level of chloride in stool suggested CCD and she was thus treated with IV fluid replacement, Total parentral nutrition and high dose of oral omeprazole (3 mg/kg/day). She gained 1 kg of weight and is doing fine until present. CCD is a rare hereditary cause of intractable diarrhea of infancy. It should be considered in infants with unknown severe electrolyte disturbances.

In vitro metabolism of the pro-carcinogen aflatoxin B1 by liver preparations of the calf, nurse shark and clearnose skate.

Bodine, A B; Luer, C A; Gangjee, S A; Walsh, C J

1989-01-01

1. Liver postmitochondrial supernatant preparations of calf, clearnose skate, and nurse shark were able to metabolize the fungal toxin aflatoxin B1 to various metabolites. 2. Calf liver produced aflatoxin M1 and Q1 as the major chloroform soluble metabolites, with small amounts of aflatoxicol formed during incubation. 3. Liver preparations of the elasmobranchs, however, produced aflatoxicol as the major chloroform soluble metabolite with no other metabolite being detected. 4. The water soluble metabolite profiles for the three species were also quite different with the tris diol adduct being produced to a much greater extent in calf liver preparations. 5. Aflatoxicol production by the elasmobranch liver homogenates was reversible with the skate reconverting a large amount (30%) of aflatoxicol to AFB1. The nurse shark, however, appeared to convert a portion of aflatoxicol to an unknown metabolite more polar than AFB1. 6. Calf liver DNA bound approximately 3 x more 3H-AFB1 than shark liver DNA.

Blastocystis hominis and Cryptosporidium sp. are commonly associated with immunocompromised patients. Severe clinical manifestation can be produced by this organism. It varies according to immune status, and subtype of this organism. Unfortunately, we found an immunocompetent patient with chronic diarrhea caused by this organism. A 38- year old male was admitted to Adam Malik General Hospital because of watery diarrhea since four days ago. Administration of fluid replacement was done to this patient, but the frequency of diarrhea did not decrease. Loperamide as anti-spasmodic was also given in each episode of diarrhea. Surprisingly, fecal smear examination revealed that this patient positive for Blastocystis hominis and Cryptosporidium sp. Thus, diarrhea was resolved for four days without giving any anti-parasitic drugs to the patient.

Neonatal retinoblastoma

Tero T Kivelä

2017-01-01

Full Text Available From 7% to 10% of all retinoblastomas and from 44% to 71% of familial retinoblastomas in developed countries are diagnosed in the neonatal period, usually through pre- or post-natal screening prompted by a positive family history and sometimes serendipitously during screening for retinopathy of prematurity or other reasons. In developing countries, neonatal diagnosis of retinoblastoma has been less common. Neonatal retinoblastoma generally develops from a germline mutation of RB1, the retinoblastoma gene, even when the family history is negative and is thus usually hereditary. At least one-half of infants with neonatal retinoblastoma have unilateral tumors when the diagnosis is made, typically the International Intraocular Retinoblastoma Classification (Murphree Group B or higher, but most germline mutation carriers will progress to bilateral involvement, typically Group A in the fellow eye. Neonatal leukokoria usually leads to the diagnosis in children without a family history of retinoblastoma, and a Group C tumor or higher is typical in the more advanced involved eye. Almost all infants with neonatal retinoblastoma have at least one eye with a tumor in proximity to the foveola, but the macula of the fellow eye is frequently spared. Consequently, loss of reading vision from both eyes is exceptional. A primary ectopic intracranial neuroblastic tumor known as trilateral retinoblastoma is no more common after neonatal than other retinoblastoma. For many reasons, neonatal retinoblastoma may be a challenge to eradicate, and the early age at diagnosis and relatively small tumors do not guarantee the preservation of both eyes of every involved child. Oncology nurses can be instrumental in contributing to better outcomes by ensuring that hereditary retinoblastoma survivors receive genetic counseling, by referring families of survivors to early screening programs when they are planning for a baby, and by providing psychological and practical support

2007-09-01

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

Full Text Available Staphylococcal diarrhea is a common gastro-intestinal illness caused by poor water supply and unhygienic food preparation. Although, about 70% of diarrheal cases per year have been attributed to the consumption of contaminated foods, in Africa, few studies have reported the incidence of Staphylococcus-related diarrhea and the implicated virulence factors. We investigated the implications of common factors such as age of children, age of mothers, maternal level of education, gender of children, overall bacteria isolated, sanitary condition status and feeding type of mothers on the burden of staphylococcal diarrhea. A literature search was performed using Pubmed, Googlescholar, American society for microbiology (ASM journals and other sources. The quality of studies was assessed. Adjusted odds ratios with 95% confidence intervals (CI for the occurrence of Staphylococcus aureus amongst other causes were extracted. For each study, a multivariate logistic regression analysis of the adjusted odds ratio was performed to identify the risk factors on the burden of staphylococcal diarrhea. Six case-control studies were included in the meta–analysis. Quality of individual studies rages from 0.57–0.84 (median, 0.69. meta-analysis gave pooled odds ratios 3.27 (95% CI; 2.88–4.17. The results identified inadequate sanitary conditions and type of feeding as major risk factors.

Environmental Decision Analysis: Meeting the Challenges of Making Good Decisions at CALFED

Directory of Open Access Journals (Sweden)

Claire D Tomkins

2006-09-01

Full Text Available We present a methodology to support decision making at CALFED based on the principles of decision analysis, an analytical approach to decision making designed to handle complex decisions involving both uncertainty and multiple dimensions of value. The impetus for such an approach is a recognized need to enhance communication between scientists and management and between program elements within CALFED. In addition, the environmental decision analysis framework supports both the explicit representation of uncertainty in the decision problem and communication about risk, important elements of most environmental management decisions. The decision analysis cycle consists of four phases: 1 formulate, 2 evaluate, 3 appraise, and 4 decide. In phase one, we identify the objectives and also the alternatives, or possible actions. To facilitate inter-comparison between proposed actions, we recommend formulation of a set of common metrics for CALFED. In our pilot study, we introduced common metrics for salinity, winter-run Chinook salmon survival, and habitat health. The second phase focuses on quantifying possible impacts on the set of metrics, drawing on existing data, model runs, and expert opinions. For the evaluation phase, we employ tools such as decision trees to assess the system-wide impacts of a given action. In the final phase, tools such as expected cost-benefit analysis, value contribution diagrams, and 3-D tradeoff plots aid communication between various stakeholders, scientists, and managers. While decision analysis provides a spectrum of decision support tools, we emphasize that it does not dictate a solution but rather enhances communication about tradeoffs associated with different actions.

Full Text Available Abstract Background It has been reported that calf oocytes are less developmentally competent than oocytes obtained from adult cows. Bone morphogenetic protein 15 (BMP15 and growth and differentiation factor 9 (GDF9 play critical roles in folliculogenesis, follicular development and ovulation in mammalian ovaries. In the present study, we attempted to compare the expression patterns of BMP15 and GDF9 in the cells of calf and cow ovaries to determine a relationship between the level of these genes and the low developmental competence of calf oocytes. Methods Bovine tissues were collected from 9-11 months-old calves and from 4-6 years-old cows. We characterized the gene expression of BMP15 and GDF9 in calf and adult bovine oocytes and cumulus cells using quantitative real-time reverse transcriptase polymerase chain reaction (QPCR and in situ hybridization. Immunohistochemical analysis was also performed. Results The expression of BMP15 and GDF9 in cumulus cells of adult ovaries was significantly higher than that in calf ovaries, as revealed by QPCR. GDF9 expression in the oocytes of calf ovaries was significantly higher than in those of the adult ovaries. In contrast, BMP15 expression in the oocytes of calf and adult ovaries was not significantly different. The localization of gene expression and protein were ascertained by histochemistry. Conclusions Our result showed for the first time BMP15 and GDF9 expression in bovine cumulus cells. BMP15 and GDF9 mRNA expression in oocytes and cumulus cells was different in calves and cows.

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

Direct-photo-oxidation, singlet oxygen-oxidation, or photosensitized oxidation can modify lens crystallins, causing an increase in blue fluorescence and covalent crosslinking. A relationship between these changes has not been elucidated. We now report results from experiments with ozone oxidation. When calf-lens alpha-crystallin is treated with zone oxidation. When calf-lens alpha-crystallin is treated with ozone, new absorption, fluorescence, and phosphorescence, which are characteristic of the oxidized product of tryptophan (N-formylkynurenine), appear at 320, 435, and 445 nm, respectively. In addition, in this ozonization of alpha-crystallin, its polypeptides are crosslinked by nondisulfide bonds. Irradiation of ozone-treated alpha-crystallin with near-ultraviolet (365 nm) light increases crosslinking and reduces the 320 nm absorbance with a concomitant appearance of a new absorption at about 420 nm. This photoproduct exhibits an intense fluorescence around 450 nm and a weak phosphorescence at 510 nm, with excitation peaks at 400, 415, and 422 nm. These findings are essentially the same as those observed in photo-oxidized alpha-crystallin, suggesting the involvement of the same tryptophan oxidized product in the modification of the lens protein

Full Text Available led to the deaths of several newborn barren-ground caribou (Rangifer tarandus groenlandicus calves within a short period of time and on a small area. This event took place during calving in June 1958 on the calving ground of the Beverly caribou herd in the Northwest Territories. The lack of other examples of multiple deaths of newborn caribou calves from intraspecific strife and our findings on the same calving ground during a study of calf mortality in June 1981, 1982, and 1983 and a study of cow-calf behaviour in June 1981 and 1982 cause us to question the published explanation. As we rarely saw aggressive behaviour among cows and newborn calves that involved actual physical contact and none that resulted in injury or death and because we found instances of multiple killings of calves by wolves {Canis lupus we suggest that a probable alternative explanation of the 1958 findings is surplus killing by wolves. Most importantly, only direct observation of an event allows separation of a death caused by injuries due to intraspecific strife from a death caused by accidental injuries.

To sonographically assess the muscle mass and architecture of sarcopenic elderly subjects, and to explore the utility of ultrasound (US) measurements in predicting sarcopenia. One hundred elderly subjects were enrolled in this cross-sectional study. Mean age value of our study population was 73.08±6.18years. The diagnosis of sarcopenia was confirmed by measuring fat-free mass index (using bioelectrical impedance analysis) and handgrip strength. Calf circumference was measured and US evaluations comprised bilateral gastrocnemius muscle (MG) thickness, fascicle length and pennate angles; subcutaneous fat and dermis thicknesses in the calf. Bilateral muscle thickness and fascicle length values were significantly lower in patients with sarcopenia (both psarcopenia (all values>76.92%). Gastrocnemius muscle thickness and fascicle length values are lower in sarcopenic elderly and these two parameters can serve as alternative measurements for predicting/quantifying sarcopenia. Calf circumference measurements alone may not be appropriate for assessing sarcopenia. Instead, US imaging can conveniently be used to evaluate different compartments of the musculoskelal system in (sarcopenic) elderly. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Full Text Available Abstract Background In developing countries, mothers usually manage diarrhea at home with the pattern of management depending on perceived disease severity and beliefs. The study was carried out with the objective of determining mothers’ beliefs and barriers about diarrhea and its management. Methods Qualitative methods involving two focus group discussions and eight in-depth interviews were used to collect the data. The study was conducted at the following places: Tankisinuwari, Kanchanbari and Pokhariya of Morang district, Nepal during the months of February and March 2010. Purposive sampling method was adopted to recruit twenty mothers based on the inclusion criteria. A semi-structured interview guide was used to conduct the interviews. Written informed consent was obtained from all of the participants before conducting the interviews. The interviews were moderated by the main researcher with the support of an expert observer from Nobel Medical College. The interviews were recorded with the permission of the participants and notes were written by a pre trained note-taker. The recordings were transcribed verbatim. All the transcribed data was categorized and analyzed using thematic content analysis. Results Twenty mothers participated in the interviews and most (80% of them were not educated. About 75% of the mothers had a monthly income of up to 5000 Nepalese rupees (US$ 60.92. Although a majority of mothers believed diarrhea to be due to natural causes, there were also beliefs about supernatural origin of diarrhea. Thin watery diarrhea was considered as the most serious. There was diversity in mothers’ beliefs about foods/fluids and diarrhea management approaches. Similarly, several barriers were noted regarding diarrhea prevention and/or management such as financial weakness, lack of awareness, absence of education, distance from healthcare facilities and senior family members at home. The elderly compelled the mothers to visit

To investigate the nutrient effect of glutamine on small intestinal repair in weanling rats after chronic diarrhea. Forty 21-day-old wistar rats were randomly divided into five groups (8 in each). Animal model of chronic diarrhea was induced by a lactose enriched diet in the weanling Wistar rat, normal control group was fed with a standard semipurified diet, and after 14 days the rats in both groups were killed to test the establishment of the model. After the establishment of the model, the other groups were fed with the standard semipurified diet to recover for 7 days, and were randomly divided into three groups: non-intervention group, glutamine (Gln)-intervention group and control group. Glutamine concentrations in blood was detected by high-performance liquid chromatography (HPLC). Morphological changes including villus height and villus surface area of the jejunum were measured under a light microscope and electron microscope, expression of proliferating cell nuclear antigen (PCNA) as an index of cell proliferation was observed using immunohistochemical staining and image analysis. The diarrhea rate in model group was 100 percent, average diarrhea index was 1.16 +/- 0.06, but both diarrhea rate and average diarrhea index in control group were 0 (P body weight, plasma Gln concentration, villus height, villus surface area and expression of PCNA in non-intervened group compared with the control group (P body weight, villus height and villus surface area in Gln-intervened group compared with control group (P 0.05). And compared with non-intervened group, except for body weight (P > 0.05), plasma glutamine, villus height, villus surface area and expression of PCNA were all significantly increased in Gln-intervened group. Chronic diarrhea can induce malnutrition and reduce the villus height, villus surface area, expression of PCNA and plasm glutamine concentration. Oral glutamine could improve the proliferation of crypt cell and promote repair of intestinal mucosa

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

Full Text Available Neonatal diarrhea determines significant changes in feed conversion, causing productivity loss in caprine herds. The antimicrobial resistance in bacteria is characterized as an important public health issue; therefore, Escherichia coli may be characterized as an important pathogen due to expressing virulence mechanisms responsible for significant clinical conditions in humans and animals. The present study evaluated the presence of E. coli among 117 caprine fecal samples and analyzed the isolates for antimicrobial resistance. Suggestive colonies were submitted to biochemical screening followed by genotypic group determination and phylogenetic analysis; further, the samples were submitted to antimicrobials susceptibility test. E. coli, Salmonella spp, Shigella sonnei and Enterobacter aerogenes were identified. E. coli isolates were phylogenetically classified as B2 (9/39, D (19/39, B1 (7/39 e A (4/29 groups. The analysis of the isolates also revealed the presence of K99 (04/39 and Stx (02/39 virulence factors. Antimicrobial susceptibility test revealed sensitive isolates to Chloramphenicol, Streptomycin, Amoxicillin and Ciprofloxacin, being all resistant to Lincomycin, Vancomycin and Penicillin. The results support the need of establishing restricted protocols for antimicrobial use, a fundamental procedure for health improvement in Brazilian caprine herds.

Full Text Available The effects of climatic and density-dependent factors on calf production and carcass weights of reindeer calves were studied between the years 1965-87 in the Oraniemi co-operative, Finnish Lapland (67°50´N. The Oraniemi area is divided into five pasture regions, in which the annual home range of the reindeer varied from 300 to 600 km2. The more than trebled reindeer density over the period 1965-87 in Oraniemi had no detrimental effect on calf production (range 15-74 calves/100 females, nor on the mean carcass weight of the calves in 1974-87 (range 16.8-23.2 kg. The annual variations in calf% were explained best by snow conditions during the previous winter and spring and their effects on the nutritional status of the females. The carcass weights of the calves were greater following a warm, rainy May and lower following a warm, rainy June and July. The weather in spring affects the emergence of green vegetation, which is reflected in the condition of females and their milk production, while the weather in early and mid-supper probably affects the quantities of blood-sucking insects and their activity. Carcass weights upon slaughtering rose from September to the beginning of December but then fell quickly. The differences in reindeer densities between the five pasture regions was not reflected in the calf% over the period 1984-87, but the carcass weights of calves were lower following high densities in the pasture regions, especially in the winter pastures.

Systemic therapy-induced diarrhea (STID) is a common side effect experienced by more than half of cancer patients. Despite STID-associated complications and poorer quality of life (QoL), no validated assessment tools exist to accurately assess STID occurrence and severity to guide clinical management. Therefore, we developed and validated a patient-reported questionnaire (STIDAT). The STIDAT was developed using the FDA iterative process for patient-reported outcomes. A literature search uncovered potential items and questions for questionnaire construction used by oncology clinicians to develop questions for the preliminary instrument. The instrument was evaluated on its face validity and content validity by patient interviews. Repetitive, similar and different themes uncovered from patient interviews were implemented to revise the instrument to the version used for validation. Patients starting high-risk STID treatments were monitored using the STIDAT, bowel diaries and EORTC QLQ-C30. The STIDAT was evaluated for construct validity using exploratory factor analysis (EFA) using minimal residual method with Promax rotation, reliability and consistency. A weighted scoring system was developed and a receiver-operating characteristic (ROC) curve evaluated the tool's ability to detect STID occurrence. Median scores and variability were analysed to determine how well it differentiates between diarrhea severities. A post-hoc analysis determined how diarrhea severity impacted QoL of cancer patients. Patients defined diarrhea based on presence of watery stool. The STIDAT assessed patient's perception of having diarrhea, daily number of bowel movements, daily number of diarrhea episodes, antidiarrheal medication use, the presence of urgency, abdominal pain, abdominal spasms or fecal incontinence, patient's perception of diarrhea severity, and QoL. These dimensions were sorted into four clusters using EFA - patient's perception of diarrhea, frequency of diarrhea, fecal

Forage-based cow-calf operations may have detrimental impacts on the chemical status of groundwater and streams and consequently on the ecological and environmental status of surrounding ecosystems. Assessing and controlling phosphorus (P) inputs are, thus, considered the key to reducing eutrophication and managing ecological integrity. In this paper, we monitored and evaluated P concentrations of groundwater (GW) compared to the concentration of surface water (SW) P in forage-based landscape with managed cow-calf operations for 3 years (2007-2009). Groundwater samples were collected from three landscape locations along the slope gradient (GW1 10-30% slope, GW2 5-10% slope, and GW3 0-5% slope). Surface water samples were collected from the seepage area (SW 0% slope) located at the bottom of the landscape. Of the total P collected (averaged across year) in the landscape, 62.64% was observed from the seepage area or SW compared with 37.36% from GW (GW1 = 8.01%; GW2 = 10.92%; GW3 = 18.43%). Phosphorus in GW ranged from 0.02 to 0.20 mg L(-1) while P concentration in SW ranged from 0.25 to 0.71 mg L(-1). The 3-year average of P in GW of 0.09 mg L(-1) was lower than the recommended goal or the Florida's numeric nutrients standards (NNS) of 0.12 mg P L(-1). The 3-year average of P concentration in SW of 0.45 mg L(-1) was about fourfold higher than the Florida's NNS value. Results suggest that cow-calf operation in pasture-based landscape would contribute more P to SW than in the GW. The risk of GW contamination by P from animal agriculture production system is limited, while the solid forms of P subject to loss via soil erosion could be the major water quality risk from P.

It has been shown that gum arabic, a soluble fiber, enhances water, electrolyte, and glucose absorption from oral rehydration solutions in jejunal perfusion of healthy rats and in animals with theophylline-induced secretion or chronic osmotic-secretory diarrhea. This report concerns a study of the effectiveness of an oral rehydration solution supplemented with gum arabic, during recovery from chronic osmotic secretory diarrhea in free-living rats. Chronic diarrhea was induced in 60- to 80-g juvenile rats by providing a magnesium citrate-phenolphthalein solution as the sole fluid source for 7 days. This led to diarrhea characterized by dehydration, soft stools, increased cecal volume, decreased food and fluid intake and failure to gain weight. After 7 days of diarrhea, rats recovered for 24 hours with either tap water or an oral rehydration solution (90 mM Na, 111 mM glucose, 20 mM K, 80 mM chloride, 20 mM citrate) with or without 2.5 g/l gum arabic. Although all three solutions improved the diarrhea, optimal recovery from diarrhea was achieved with the gum arabic-supplemented oral rehydration solution. After 4 hours and 24 hours, rats drinking the gum arabic-supplemented solution gained more weight and had lower fecal output than rats receiving water or the rehydration solution without gum arabic. All three solutions normalized plasma osmolality after 24 hours. The positive effects of the gum arabic-supplemented rehydration solution on fluid and electrolyte absorption seen during jejunal perfusion also occurred during recovery from chronic osmotic secretory diarrhea, when free-living animals drank the solution ad libitum.

Porcine epidemic diarrhea (PED) is an intestinal infectious disease caused by porcine epidemic diarrhea virus (PEDV); manifestations of the disease are diarrhea, vomiting and dehydration. Starting from the end of 2010, a PED outbreak occurred in several pig-producing provinces in southern China. Subsequently, the disease spread throughout the country and caused enormous economic losses to the pork industry. Accumulating studies demonstrated that new PEDV variants that appeared in China were responsible for the PED outbreak. In the current mini-review, we summarize PEDV epidemiology and vaccination in China.

Full Text Available Collagenous colitis (CC is characterized by chronic secretory diarrhea with the apparently normal gross appearance of the colonic mucosa. A biopsy is usually diagnostic. The symptoms of CC appear most commonly in the elderly. In CC, the major microscopic characteristic is a thickened collagen layer beneath the colonic mucosa. The reported case represents unexplained nonbloody diarrhea of a systemic lupus erythematosus patient, on extensive evaluation found to have CC. This case highlights the importance of considering a rare possibility of CC as a differential in a patient of unexplained nonbloody diarrhea.

To investigate to what extent inter- and intramuscular variations of diffusion parameters of human calf muscles can be explained by age, gender, muscle location, and body mass index (BMI) in a specific age group (20-35 years). Whole calf muscles of 18 healthy volunteers were evaluated. Magnetic resonance imaging (MRI) was performed using a 3T scanner and a 16-channel Torso XL coil. Diffusion-weighted images were acquired to perform fiber tractography and diffusion tensor imaging (DTI) analysis for each muscle of both legs. Fiber tractography was used to separate seven lower leg muscles. Associations between DTI parameters and confounds were evaluated. All muscles were additionally separated in seven identical segments along the z-axis to evaluate intramuscular differences in diffusion parameters. Fractional anisotropy (FA) and mean diffusivity (MD) were obtained for each muscle with low standard deviations (SDs) (SD FA : 0.01-0.02; SD MD : 0.07-0.14(10 -3 )). We found significant differences in FA values of the tibialis anterior muscle (AT) and extensor digitorum longus (EDL) muscles between men and women for whole muscle FA (two-sample t-tests; AT: P = 0.0014; EDL: P = 0.0004). We showed significant intramuscular differences in diffusion parameters between adjacent segments in most calf muscles (P < 0.001). Whereas muscle insertions showed higher (SD 0.03-0.06) than muscle bellies (SD 0.01-0.03), no relationships between FA or MD with age or BMI were found. Inter- and intramuscular variations in diffusion parameters of the calf were shown, which are not related to age or BMI in this age group. Differences between muscle belly and insertion should be considered when interpreting datasets not including whole muscles. 3 Technical Efficacy: Stage 1 J. Magn. Reson.

We performed a systematic literature review and meta-analysis examining the association between diarrhea in young children in nonindustrialized settings and Giardia lamblia infection. Eligible were case/control and longitudinal studies that defined the outcome as acute or persistent (>14 days) diarrhea, adjusted for confounders and lasting for at least 1 year. Data on G. lamblia detection (mainly in stools) from diarrhea patients and controls without diarrhea were abstracted. Random effects model meta-analysis obtained pooled odds ratios (ORs) and 95% confidence intervals (CIs). Twelve nonindustrialized-setting acute pediatric diarrhea studies met the meta-analysis inclusion criteria. Random-effects model meta-analysis of combined results (9774 acute diarrhea cases and 8766 controls) yielded a pooled OR of 0.60 (95% CI, .38–.94; P = .03), indicating that G. lamblia was not associated with acute diarrhea. However, limited data suggest that initial Giardia infections in early infancy may be positively associated with diarrhea. Meta-analysis of 5 persistent diarrhea studies showed a pooled OR of 3.18 (95% CI, 1.50–6.76; P diarrhea in children in developing countries. PMID:23169940

Prescription of an appropriate dialysis target weight (dry weight) requires accurate evaluation of the degree of hydration. The aim of this study was to investigate whether a state of normal hydration (DW cBIS ) as defined by calf bioimpedance spectroscopy (cBIS) and conventional whole body bioimpedance spectroscopy (wBIS) could be characterized in hemodialysis (HD) patients and normal subjects (NS). wBIS and cBIS were performed in 62 NS (33 m/29 f) and 30 HD patients (16 m/14 f) pre- and post-dialysis treatments to measure extracellular resistance and fluid volume (ECV) by the whole body and calf bioimpedance methods. Normalized calf resistivity (ρ N,5 ) was defined as resistivity at 5 kHz divided by the body mass index. The ratio of wECV to total body water (wECV/TBW) was calculated. Measurements were made at baseline (BL) and at DW cBIS following the progressive reduction of post-HD weight over successive dialysis treatments until the curve of calf extracellular resistance is flattened (stabilization) and the ρ N,5 was in the range of NS. Blood pressures were measured pre- and post-HD treatment. ρ N,5 in males and females differed significantly in NS. In patients, ρ N,5 notably increased with progressive decrease in body weight, and systolic blood pressure significantly decreased pre- and post-HD between BL and DW cBIS respectively. Although wECV/TBW decreased between BL and DW cBIS , the percentage of change in wECV/TBW was significantly less than that in ρ N,5 (−5.21 ± 3.2% versus 28 ± 27%, p < 0.001). This establishes the use of ρ N,5 as a new comparator allowing a clinician to incrementally monitor removal of extracellular fluid from patients over the course of dialysis treatments. The conventional whole body technique using wECV/TBW was less sensitive than the use of ρ N,5 to measure differences in body hydration between BL and DW cBIS

Experiments were performed to study the internal transport and biological availability of radioactive lead that could be produced and released in certain types of nuclear cratering events, especially lead 203 and lead 210. A lactating dairy cow was used for the metabolic experiments, and a calf was used for the tissue distribution study. Urine, feces, blood, and milk samples from the cow were analyzed for each 24 hour period. Blood plasma and representative organs and tissues were removed from the calf and analyzed. Results showed a total recovery of 94.768% of the /sup 203/Pb in the feces, urine and milk of the cow by 144 hr. Approximately 85% was recovered in the feces in the first 48 hr. The total secretion in urine during 144 hr. was 0.173%, while the total secretion in milk was 0.190. These results reveal the slow, incomplete absorption of lead from the digestive tract. In the calf the tissue distribution of the absorbed lead shows that the erythrocytes represents the largest pool of lead in respect to recovery value. The tissue data confirm the known pattern of distribution of inorganic lead in soft tissues, with the highest concentrations in the liver and kidneys.

Children's stool disposal is often overlooked in sanitation programs of any country. Unsafe disposal of children's stool makes children susceptible to many diseases that transmit through faecal-oral route. Therefore, the study aims to examine the magnitude of unsafe disposal of children's stools in India, the factors associated with it and finally its association with childhood diarrhea. Data from the third round of the National Family Health Survey (NFHS-3) conducted in 2005-06 is used to carry out the analysis. The binary logistic regression model is used to examine the factors associated with unsafe disposal of children's stool. Binary logistic regression is also used to examine the association between unsafe disposal of children's stool and childhood diarrhea. Overall, stools of 79% of children in India were disposed of unsafely. The urban-rural gap in the unsafe disposal of children's stool was wide. Mother's illiteracy and lack of exposure to media, the age of the child, religion and caste/tribe of the household head, wealth index, access to toilet facility and urban-rural residence were statistically associated with unsafe disposal of stool. The odds of diarrhea in children whose stools were disposed of unsafely was estimated to be 11% higher (95% CI: 1.01-1.21) than that of children whose stools were disposed of safely. An increase in the unsafe disposal of children's stool in the community also increased the risk of diarrhea in children. We found significant statistical association between children's stool disposal and diarrhea. Therefore, gains in reduction of childhood diarrhea can be achieved in India through the complete elimination of unsafe disposal of children's stools. The sanitation programmes currently being run in India must also focus on safe disposal of children's stool.

Role of colonic short-chain fatty acid transport in diarrhea.

Science.gov (United States)

Binder, Henry J

2010-01-01

Short-chain fatty acids (SCFA) are the major anion in stool and are synthesized from nonabsorbed carbohydrate by the colonic microbiota. Nonabsorbed carbohydrate are not absorbed in the colon and induce an osmotically mediated diarrhea; in contrast, SCFA are absorbed by colonic epithelial cells and stimulate Na-dependent fluid absorption via a cyclic AMP-independent process involving apical membrane Na-H, SCFA-HCO(3), and Cl-SCFA exchanges. SCFA production represents an adaptive process to conserve calories, fluid, and electrolytes. Inhibition of SCFA synthesis by antibiotics and administration of PEG, a substance that is not metabolized by colonic microbiota, both result in diarrhea. In contrast, increased production of SCFA as a result of providing starch that is relatively resistant to amylase digestion [so-called resistant starch (RS)] to oral rehydration solution (RS-ORS) improves the efficacy of ORS and represents an important approach to improve the effectiveness of ORS in the treatment of acute diarrhea in children under five years of age.

Gastrointestinal complications from antibiotic use, including Clostridium difficile infection (CDI), can have significant morbidity, especially among older patients. This descriptive study surveyed dentists to find out how they would respond to a patient with signs indicating potential CDI. A survey on prescribing medications for older patients was mailed to 1,000 dentists in New Jersey. Questions were asked regarding antibiotic selection, probiotic use, and approach to a patient scenario of diarrhea after antibiotic use. Respondents chose amoxicillin most frequently as an antibiotic, and clindamycin if penicillin allergy. When informed their patients had diarrhea, 64.5% advised them to stop the antibiotic. If the patient continued to have diarrhea on follow-up, 75.5% contacted the patient's physician. Most (61.6%) do not prescribe probiotics prophylactically. Most dentists respond appropriately to antibiotic-associated diarrhea in advising to stop the antibiotic, and seeking physician involvement if no improvement, but there are still many who make recommendations that could delay appropriate care. Dentists may wish to learn more about benefits of probiotics. © 2015 Special Care Dentistry Association and Wiley Periodicals, Inc.

Full Text Available During early developmental stages, cetacean calves are dependent on their mothers for survival. Protection of young whales engaged in behaviors that are biologically important is critical for population recovery, so that appropriate management actions can be taken to minimize human disturbance. However, the occurrence and frequency of whale nursing and calves back-riding their mothers (both considered important to calf survival have rarely been observed nor adequately quantified or defined. Therefore, it may not always be clear when disruption is occurring. We used extended behavioral observations, still photography, and video camera footage obtained during aircraft surveys in the Southern California Bight in 2008 – 2013 to characterize cetacean mother-calf interactions. Based on observations of four mother/calf pairs (two gray whale, Eschrichtius robustus, one fin whale, Balaenoptera physalus, and one blue whale, B. musculus and one killer whale presumed mother/yearling pair (Orcinus orca, we describe bouts of nursing and calves riding on the backs of their presumed mothers, including activity duration, frequency, and relative body positioning. We conclude with specific definitions useful to wildlife conservation agencies authorizing and establishing restrictions to certain human activities when they might constitute behavioral disruptions.

Neonatal neurology is a growing sub-specialty area. Given the considerable amount of neurologic problems present in the neonatal intensive care unit, a neurologist with expertise in neonates is becoming more important. We sought to evaluate the change in neurologic care in the neonatal intensive care unit at our tertiary care hospital by having a dedicated neonatal neurologist. The period post-neonatal neurologist showed a greater number of neurology consultations (Pneurology encounters per patient (Pneurology became part of the multi-disciplinary team providing focused neurologic care to newborns.

Using a single-group time-series design, we determined that osmotic diarrhea caused by maltitol ingestion was suppressed by the addition of not only soluble but also insoluble dietary fiber in healthy humans. We then clarified that cellulose delayed gastric emptying in rats. Twenty-seven healthy volunteers ingested maltitol step-wise at doses of 15, 20, 25, 30, 35, 40 and 45 g from small to large amounts. Within that range of ingested amounts, 22 out of 27 subjects experienced osmotic diarrhea from maltitol ingestion, and the minimal dose level of maltitol that induced osmotic diarrhea (MMD) was established for each subject. When 5 g of cellulose was added to the MMD, osmotic diarrhea was suppressed in 13 out of 19 subjects (68.4%), while partially hydrolyzed alginate-Na (PHA-Na), a soluble dietary fiber, suppressed osmotic diarrhea in 10 out of 20 subjects (50.0%). When a mixed solution of cellulose and maltitol was administered to rats, the gastric emptying of maltitol was significantly delayed at 30 and 60 min after administration (p=0.019, p=0.013), respectively. PHA-Na also significantly delayed gastric emptying at 30 min (p=0.013). In conclusion, cellulose can suppress the osmotic diarrhea caused by maltitol ingestion in humans and delay the gastric emptying of maltitol in rats. A new physiological property of cellulose was clarified in this study.

Extracellular Calcium Dictates Onset, Severity, and Recovery of Diarrhea in a Child with Immune-Mediated Enteropathy

Full Text Available Diarrhea causes monovalent and divalent ion losses that can influence clinical outcome. Unlike the losses of monovalent ions, such as Na+, K+, Cl−, and HCO3−, which are generally large in quantity (osmoles and therefore determine the severity of diarrhea, the losses of divalent ions are relatively small in osmoles and are often overlooked during diarrheal treatment. Studies now suggest that despite divalent ions being small in osmoles, their effects are large due to the presence of divalent ion-sensing receptors and their amplifying effects in the gut. As a result, losses of these divalent ions without prompt replacement could also significantly affect the onset, severity, and/or recovery of diarrheal disease. Herein, we report a case of a malnourished child with an immune-mediated enteropathy who developed episodes of “breakthrough” diarrhea with concurrent hypocalcemia while on appropriate immunotherapy. Interestingly, during these periods of diarrhea, stool volume fluctuated with levels of blood Ca2+. When Ca2+ was low, diarrhea occurred; when Ca2+ levels normalized with replacement, diarrhea stopped. Based on this and other observations, a broader question arises as to whether the Ca2+ lost in diarrhea should be replaced promptly in these patients.

2018-03-01

Full Text Available Background The popularity of probiotics is on the rise. Despite the beneficial effects of antibiotics, gastrointestinal health is at risk of diarrhea. This study aimed to investigate whether probiotic yogurt is of capability to prevent the incidence of diarrhea versus conventional yogurt. Materials and Methods This controlled, randomized, double-blind trial was designed to recruit 48 hospitalized children, whose treatments included different types of antibiotics. They were subsequently assigned into a 1:1 ratio into groups A and B at random. The first group was instructed to consume probiotic yogurt (Bifidobacterium strains and Lactobacillus acidophilus, while the second were on conventional yogurt (placebo containing Streptococcus thermophiles and Lactobacillus bulgaricus at least for 7 days. The incidence of diarrhea, its onset and duration were compared between the two groups. Results The findings indicated that there was no statistically significant difference between the experimental and control groups (p > 0.05. No significant decrease was observed in the incidence of diarrhea between the groups following adjustment for negative C-reactive protein (CRP (p > 0.05. Conclusion According to the results, the consumption of yogurt, either probiotic or conventional, reduced the incidence, duration, and onset of antibiotic-associated diarrhea in pediatric population. This study showed no significantly better performance for probiotic yogurt than conventional yogurt.

Bovine virus diarrhea (BVD) is a complicated disease to discuss as it can result in a wide variety of disease problems from very mild to very severe. BVD can be one of the most devastating diseases cattle encounter and one of the hardest to get rid of when it attacks a herd. The viruses that cause BVD have been grouped into two genotypes, Type I and Type II. The disease syndrome caused by the two genotypes is basically the same, however disease caused by Type II infection is often more severe...

To consider the relationship of the parasitic infections including cryptosporidium with chronic diarrhea. Also the effect of chronic disease as pulmonary tuberculosis (TB) and nosocomial infection on the occurrence rate of parasites in cases of chronic diarrhea. Stool samples were collected from 205 patients in teaching, general, child and maternity hospitals in Basrah, Iraq, suffering from chronic diarrhea during 2000. Out of these patients, there were 40 patients with pulmonary TB and 50 inpatients with nosocomial infection. Also 175 apparently healthy individuals who have no episodes of diarrhea for at least 2-months were served as a control group. Direct smear method and then formalin ether sedimentation method were carried out for stool samples to detect intestinal parasites. Fecal smears were prepared from the sediment and stained by the modified Ziehl Neelsen stain for the recovery of red pink oocysts of cryptosporidium. Out of the 205 examined patients, cryptosporidium oocysts were found to be excreted in 20 (9.7%) patients in comparing to 1.1% of the control group. The difference is statistically significant. There were 109 (53.2%) patients found to be positive for intestinal parasitic infections compared to 26 (14.8%) of the control group. The difference is also statistically significant. Out of the 40 TB patients, 2 (5%) were found to excrete cryptosporidium oocysts and also 27 (67.3%) were positive for intestinal parasites. In addition, there were 4 (8%) excreting cryptosporidium oocysts and 23 (46%) infecting by intestinal parasites among the in patients with nosocomial infection. Both acid and non-acid fast parasites should be considered in the differential diagnosis of undiagnosed chronic diarrhea especially among patients with pulmonary TB or nosocomial infection.

2003-01-01

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

Full Text Available Lapatinib and capecitabine have been widely used in the therapy of breast cancer. However, long-term use of lapatinib and capecitabine often causes the most common side effect diarrhea, which limit the medicine use. Fructus mume (F. mume has been proved to be effective to treat chronic diarrhea with few side effects. The compounds from F. mume were extracted by using an ethanol method. Extracts of F. mume (EFM were analyzed by HPLC. We investigated the protective effects of EFM on the diarrhea caused by lapatinib and capecitabine. From March 1st, 2016 to June 1st, 2017, 208 breast cancer patients with diarrhea caused by lapatinib and capecitabine were recruited. The patients were evenly assigned into two groups: EG group (the patients took 100 mg EFM daily and CG group (the patients took placebo daily. The effects of EFM on diarrhea and gastrointestinal symptoms were measured by a semiquantitative method seven-point Likert scale. Overall quality of life was measured by SF-36 questionnaire and Hospital Anxiety and Depression Scale (HADS. The HPLC analysis showed that there were three components in EFM, including citric acid, 5-hydroxymethylfurfural (5-HMF, and chlorogenic acid. Breast cancer types were observed by using Hematoxylin and eosin (H&E stain. The breast cancer can be divided into leaflet, gland and fibroblast types. Patient age, skin metastases, treatment, and grade 1 diarrhea were significant risk factors associated with for grade 2 diarrhea. EFM reduced diarrhea and gastrointestinal symptoms by reducing the average scores of the diarrhea symptom and seven-point Likert scale, and improved life quality of patients significantly by improving SF-36 scores and reducing HADS scores when compared to that in the CG group after 6-week therapy and further 4-week follow-up (P < 0.05. EFM may be a potential choice for the diarrhea therapy in breast cancer patients.

Full Text Available Diarrheal disease remains a leading cause of death in children in low-income countries. We investigated the etiology, risk factors and effects on nutritional status of severe diarrhea in children from two districts in Madagascar.We performed a matched case-control study in 2011 to 2014, on children under the age of five years from Moramanga and Antananarivo. The cases were children hospitalized for severe diarrhea and the controls were children without diarrhea selected at random from the community. Stool samples were collected from both groups. Anthropometric measurements were made during follow-up visits about one and two months after enrolment.We enrolled 199 cases and 199 controls. Rotavirus infection was the most frequently detected cause of diarrhea. It was strongly associated with severe diarrhea (OR: 58.3; 95% CI: 7.7-439.9, accounting for 42.4% (95% CI: 37.6-43.1 of severe diarrhea cases. At the household level, possession of cattle (OR = 0.3; 95% CI: 0.1-0.6 and living in a house with electricity (OR = 0.4; 95% CI: 0.2-0.8 were protective factors. The presence of garbage around the house was a risk factor for severe diarrhea (OR = 3.2; 95% CI: 1.9-5.4. We found no significant association between severe diarrhea and the nutritional status of the children at follow-up visits, but evident wasting at enrolment was associated with a higher risk of severe diarrhea (OR = 9; 95% CI: 4.5-17.9.Severe childhood diarrhea is mostly caused by rotavirus infection. An anti-rotavirus vaccine has already been introduced in Madagascar and should be promoted more widely. However, post-licensing surveillance is required. Interventions to improve the nutritional status of children, preventive measures focused on household and personal hygiene and nutritional rehabilitation during severe diarrheal disease should be reinforced.

The PigIT Project aims at improving welfare and production of slaughter pigs by integration of various sensor systems for alarm purposes. Here we present an exploratory analysis to assess the predictive value of temperature sensor data with respect to pen fouling and diarrhea. We recorded...... the temperature at four locations in two double-pens (by the drinking nipples and by the corridor) between November 2013 and December 2014. Logistic regression models were made to express the probability of fouling and diarrhea per day, and were reduced via backwards elimination. Furthermore, fitting the models...... was attempted with the raw temperature data as well as data averaged over 10, 15, 30 and 60 minutes. The predictive performances were evaluated with Matthews Correlation Coefficient (MCC). For diarrhea, the minimal and maximal temperatures at the water nipple and the corridor, as well as the maximal rate...

The purpose of these studies was to gain insight into the pathophysiology of pure osmotic diarrhea and the osmotic diarrhea caused by carbohydrate malabsorption. Diarrhea was induced in normal volunteers by ingestion of polyethylene glycol (PEG), which is nonabsorbable, not metabolized by colonic bacteria, and carries no electrical charge. In PEG-induced diarrhea, (a) stool weight was directly correlated with the total mass of PEG ingested; (b) PEG contributed 40-60% of the osmolality of the fecal fluid, the remainder being contributed by other solutes either of dietary, endogenous, or bacterial origin; and (c) fecal sodium, potassium, and chloride were avidly conserved by the intestine, in spite of stool water losses exceeding 1,200 g/d. Diarrhea was also induced in normal subjects by ingestion of lactulose, a disaccharide that is not absorbed by the small intestine but is metabolized by colonic bacteria. In lactulose-induced diarrhea, (a) a maximum of approximate 80 g/d of lactulose was metabolized by colonic bacteria to noncarbohydrate moieties such as organic acids; (b) the organic acids were partially absorbed in the colon; (c) unabsorbed organic acids obligated the accumulation of inorganic cations (Na greater than Ca greater than K greater than Mg) in the diarrheal fluid; (d) diarrhea associated with low doses of lactulose was mainly due to unabsorbed organic acids and associated cations, whereas with larger doses of lactulose unmetabolized carbohydrates also played a major role; and (e) the net effect of bacterial metabolism of lactulose and partial absorption of organic acids on stool water output was done dependent. With low or moderate doses of lactulose, stool water losses were reduced by as much as 600 g/d (compared with equimolar osmotic loads of PEG); with large dose, the increment in osmotically active solutes within the lumen exceeded the increment of the ingested osmotic load, and the severity of diarrhea was augmented.

2009-01-01

We report on a case of isolated tear of the medial head of gastrocnemius tendon. The patient presented with a painless lump in the right calf and denied any prior history of trauma or strain to the leg. A longitudinal split of the tendon was demonstrated at ultrasound and magnetic resonance imaging (MRI). There were no other abnormalities and the gastrocnemius muscle was normal. There are no reports in the literature of isolated gastrocnemius tendon tear. To date the calf muscle complex injury described in this area is tearing of the medial head of gastrocnemius muscle, sometimes referred to as "tennis leg". We conclude that an isolated tear of the tendon to the medial head of gastrocnemius should be considered in the differential diagnosis of a lump or swelling in the upper medial area of the calf and we recommend ultrasound or MRI as the investigations of choice.

Purpose Hypocalcemia is a common endocrinological condition in 22q11.2 deletion syndrome. Neonatal hypocalcemia may affect neurodevelopment. We hypothesized that neonatal hypocalcemia would be associated with rare, more severe forms of intellectual disability in 22q11.2 deletion syndrome. Methods We used a logistic regression model to investigate potential predictors of intellectual disability severity, including neonatal hypocalcemia, neonatal seizures, and complex congenital heart disease, e.g., interrupted aortic arch, in 149 adults with 22q11.2 deletion syndrome. Ten subjects had moderate-to-severe intellectual disability. Results The model was highly significant (P < 0.0001), showing neonatal seizures (P = 0.0018) and neonatal hypocalcemia (P = 0.047) to be significant predictors of a more severe level of intellectual disability. Neonatal seizures were significantly associated with neonatal hypocalcemia in the entire sample (P < 0.0001), regardless of intellectual level. There was no evidence for the association of moderate- to-severe intellectual disability with other factors such as major structural brain malformations in this sample. Conclusion The results suggest that neonatal seizures may increase the risk for more severe intellectual deficits in 22q11.2 deletion syndrome, likely mediated by neonatal hypocalcemia. Neonatal hypocalcemia often remains unrecognized until the postseizure period, when damage to neurons may already have occurred. These findings support the importance of early recognition and treatment of neonatal hypocalcemia and potentially neonatal screening for 22q11.2 deletions. PMID:23765047

2018-02-01

Stress-induced diarrhea is a frequent and challenging threat to humans and domestic animals. Serotonin (5-HT) has been shown to be involved in the pathological process of stress-induced diarrhea. However, the role of 5-HT in stress-induced diarrhea remains unclear. A stress-induced diarrhea model was established in 21-day-old ICR weaning mice through an intragastric administration of 0.25 mL of 0.4 g/mL folium sennae and restraint of the hind legs with adhesive tape for 4 h to determine whether 5-HT regulates the mucosal barrier to cause diarrhea. Mice with decreased levels of 5-HT were pretreated with an intraperitoneal injection of 300 mg/kg p-chlorophenylalanine (PCPA), a 5-HT synthesis inhibitor. After 5 days of treatment, the stress level, body weight and intestinal mucosal morphology indexes were measured. Compared to the controls, the mice with stress-induced diarrhea displayed a stress reaction, with increased corticosterone levels, as well as increased 5-HT-positive cells. However, the mice with stress-induced diarrhea exhibited decreased body weights, villus height to crypt depth ratios (V/C), and Occludin and Claudin1 expression. The PCPA injection reversed these effects in mice with different degrees of stress-induced diarrhea. Based on these findings, inhibition of 5-HT synthesis relieved the stress response and improved the health of the intestinal tract, including both the intestinal absorption capacity, as determined by the villus height and crypt depth, and the mucosal barrier function, as determined by the tight junction proteins of epithelial cell.

Understanding the potential links between floods and infectious diarrhea is important under the context of climate change. However, little is known about the risk of infectious diarrhea after floods and what factors could modify these effects in China. This study aims to quantitatively examine the relationship between floods and infectious diarrhea and their effect modifiers. Weekly number of infectious diarrhea cases from 2004 to 2011 during flood season in Hunan province were supplied by the National Notifiable Disease Surveillance System. Flood and meteorological data over the same period were obtained. A two-stage model was used to estimate a provincial average association and their effect modifiers between floods and infectious diarrhea, accounting for other confounders. A total of 134,571 cases of infectious diarrhea were notified from 2004 to 2011. After controlling for seasonality, long-term trends, and meteorological factors, floods were significantly associated with infectious diarrhea in the provincial level with a cumulative RR of 1.22 (95% CI: 1.05, 1.43) with a lagged effect of 0-1 week. Geographic locations and economic levels were identified as effect modifiers, with a higher impact of floods on infectious diarrhea in the western and regions with a low economic level of Hunan. Our study provides strong evidence of a positive association between floods and infectious diarrhea in the study area. Local control strategies for public health should be taken in time to prevent and reduce the risk of infectious diarrhea after floods, especially for the vulnerable regions identified.

Caldwell, Joanne N; Matsuda-Nakamura, Mayumi; Taylor, Nigel A S

2016-02-01

The inter-relationships between mean body and local skin temperatures have previously been established for controlling hand and foot blood flows. Since glabrous skin contains many arteriovenous anastomoses, it was important to repeat those experiments on non-glabrous regions using the same sample and experimental conditions. Mild hypothermia (mean body temperature 31.4 °C), normothermia (control: 36.0 °C) and moderate hyperthermia (38.3 °C) were induced and clamped (climate chamber and water-perfusion garment) in eight males. Within each condition, five localised thermal treatments (5, 15, 25, 33, 40 °C) were applied to the left forearm and right calf. Steady-state forearm and calf blood flows were measured (venous occlusion plethysmography) for each of the resulting 15 combinations of clamped mean body and local skin temperatures. Under the normothermic clamp, cutaneous blood flows averaged 4.2 mL 100 mL(-1) min(-1) (±0.28: forearm) and 5.4 mL 100 mL(-1) min(-1) (±0.27: calf). When mildly hypothermic, these segments were unresponsive to localised thermal stimuli, but tracked those changes when normothermic and moderately hyperthermic. For deep-body (oesophageal) temperature elevations, forearm blood flow increased by 5.1 mL 100 mL(-1) min(-1) °C(-1) (±0.9) relative to normothermia, while the calf was much less responsive: 3.3 mL 100 mL(-1) min(-1) °C(-1) (±1.5). Three-dimensional surfaces revealed a qualitative divergence in the control of calf blood flow, with vasoconstrictor tone apparently being released more gradually. These descriptions reinforce the importance of deep-tissue temperatures in controlling cutaneous perfusion, with this modulation being non-linear at the forearm and appearing linear for the calf.

Full Text Available The present study examined the in vitro and in vivo development of bovine nuclear-transferred embryos. A bovine fetal fibroblast culture was established and used as nucleus donor. Slaughterhouse oocytes were matured in vitro for 18 h before enucleation. Enucleated oocytes were fused with fetal fibroblasts with an electric stimulus and treated with cytochalasin D and cycloheximide for 1 h followed by cycloheximide alone for 4 h. Reconstructed embryos were cultured for 7-9 days and those which developed to blastocysts were transferred to recipient cows. Of 191 enucleated oocytes, 83 (43.5% were successfully fused and 24 (28.9% developed to blastocysts. Eighteen freshly cloned blastocysts were transferred to 14 recipients, 5 (27.8% of which were pregnant on day 35 and 3 (16.7% on day 90. Of the three cows that reached the third trimester, one recipient died of hydrallantois 2 months before term, one aborted fetus was recovered at 8 months of gestation, and one delivered by cesarian section a healthy cloned calf. Today, the cloned calf is 15 months old and presents normal body development (378 kg and sexual behavior (libido and semen characteristics.

In 1985, Silver et al. published a cadaver study which determined the relative order of strength of the muscles in the calf. Muscle strength, which is proportional to volume, was obtained by dissecting out the individual muscles, weighing them, and then multiplying by the specific gravity. No similar studies have been performed using {\\it in vivo} measurements of muscle volume. Ten normal subjects underwent 3-Tesla MRI's of both lower extremities using non-fat-saturated T2 SPACE sequences. The volume for each muscle was determined by tracing the muscle contour on sequential axial images and then interpolating the volume using imaging software. The results from this study differ from Silver's original article. The lateral head of the gastrocnemius was found to be stronger than the tibialis anterior muscle. The FHL and EDL muscles were both stronger than the peroneus longus. There was no significant difference in strength between the peroneus longus and brevis muscles. This revised order of muscle strengths in the calf based on in vivo MRI findings may assist surgeons in determining the optimal tendons to transfer in order to address muscle weakness and deformity.

Interpretation of peripheral circulation in ill neonates is crucial but difficult. The aim was to analyse parameters potentially influencing peripheral oxygenation and circulation. In a prospective observational cohort study in 116 cardio-circulatory stable neonates, peripheral muscle near-infrared spectroscopy (NIRS) with venous occlusion was performed. Tissue oxygenation index (TOI), mixed venous oxygenation (SvO 2 ), fractional oxygen extraction (FOE), fractional tissue oxygen extraction (FTOE), haemoglobin flow (Hbflow), oxygen delivery (DO 2 ), oxygen consumption (VO 2 ), and vascular resistance (VR) were assessed. Correlation coefficients between NIRS parameters and demographic parameters (gestational age, birth weight, age, actual weight, diameter of calf, subcutaneous adipose tissue), monitoring parameters (heart rate, arterial oxygen saturation (SaO 2 ), mean blood pressure (MAP), core/peripheral temperature, central/peripheral capillary refill time) and laboratory parameters (haemoglobin concentration (Hb-blood), pCO 2 ) were calculated. All demographic parameters except for Hbflow and DO 2 correlated with NIRS parameters. Heart rate correlated with TOI, SvO 2 , VO 2 and VR. SaO 2 correlated with FOE/FTOE. MAP correlated with Hbflow, DO 2 , VO 2 and VR. Core temperature correlated with FTOE. Peripheral temperature correlated with all NIRS parameters except VO 2 . Hb-blood correlated with FOE and VR. pCO 2 levels correlated with TOI and SvO 2 . The presence of multiple interdependent factors associated with peripheral oxygenation and circulation highlights the difficulty in interpreting NIRS data. Nevertheless, these findings have to be taken into account when analysing peripheral oxygenation and circulation data

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

Directory of Open Access Journals (Sweden)

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

Full Text Available ackground: Diarrhea is a disease, especially in children, with high mortality and morbidity rate in developing countries, including Indonesia. Diarrhea can be prevented if people can apply clean and healthy behaviors, especially hand washing. Hand washing is the cheapest, simplest, and the most effective methods for prevention of diarrhea. The objective of this study is to identify the knowledge, attitude, and practice of mothers’ hand washing and diarrhea cases in children under five in Baleendah District, Bandung. Methods: A descriptive study was conducted during September−November 2012 to 210 mothers who had children (ages 12−59 months in Baleendah using rapid survey technique. The time allocated for each village was adjusted to the population proportion for each region. The data were analyzed using computer and was represented using frequency distribution. Results: This study showed that the respondents had good level of knowledge and attitude of hand washing (83.8% and 61%, respectively, but only 21% of the respondents’ practices of hand washing was in good level. Most of the respondents did not wash their hands according to the 7 steps of correct hand washing. Moreover the percentage of children with diarrhea in Baleendah was 43.8% (92 cases during the study. Conclusions: There should be dissemination of information about the benefit of washing hands with 7 steps of correct hands washing so that families can practice it and can prevent diarrhea in children under five.

Full Text Available This study aims to establish a human gut microbiota (HGM transplanted gnotobiotic (Gn pig model of human rotavirus (HRV infection and diarrhea, and to verify the dose-effects of probiotics on HRV vaccine-induced immune responses. Our previous studies using the Gn pig model found that probiotics dose-dependently regulated both T cell and B cell immune responses induced by rotavirus vaccines. We generated the HGM transplanted neonatal Gn pigs through daily feeding of neonatal human fecal suspension to germ-free pigs for 3 days starting at 12 hours after birth. We found that attenuated HRV (AttHRV vaccination conferred similar overall protection against rotavirus diarrhea and virus shedding in Gn pigs and HGM transplanted Gn pigs. HGM promoted the development of the neonatal immune system, as evidenced by the significantly enhanced IFN-γ producing T cell responses and reduction of regulatory T cells and their cytokine production in the AttHRV-vaccinated pigs. The higher dose Lactobacillus rhamnosus GG (LGG feeding (14 doses, up to 109 colony-forming-unit [CFU]/dose effectively increased the LGG counts in the HGM Gn pig intestinal contents and significantly enhanced HRV-specific IFN-γ producing T cell responses to the AttHRV vaccine. Lower dose LGG (9 doses, up to 106 CFU/dose was ineffective. Neither doses of LGG significantly improved the protection rate, HRV-specific IgA and IgG antibody titers in serum, or IgA antibody titers in intestinal contents compared to the AttHRV vaccine alone, suggesting that an even higher dose of LGG is needed to overcome the influence of the microbiota to achieve the immunostimulatory effect in the HGM pigs. This study demonstrated that HGM Gn pig is an applicable animal model for studying immune responses to rotavirus vaccines and can be used for studying interventions (i.e., probiotics and prebiotics that may enhance the immunogenicity and protective efficacy of vaccines through improving the gut microbiota.

Twenty-four commercial loads of beef calves (BW 300 ± 52 kg, mean ± SD) were evaluated for associations among transportation factors, in-transit microclimate, and calf welfare. Transport factors evaluated included vehicle speed, space allowance, compartment within trailer, and transit duration. Calves were transported for 7 h 44 min ± 4 h 15 min, with space allowances ranging from 0.56 to 1.17 m(2)/animal. Compartment within trailer, space allowance, and vehicle speed did not affect the difference between compartment ceiling-level and ambient temperatures during a 30-min period of steady-state microclimate. During the steady-state period, a 1°C increase in ambient temperature above the mean of 5.6°C was associated with a 0.62°C decrease in the difference between ceiling-level and ambient temperature (P ratio; P profitability and calf welfare.

Venous thromboembolism is one of the general complications following total hip arthroplasty, wherein various preventive treatments have been recommended. Several studies reported that venous thromboembolism incidence after total hip arthroplasty was similar in patients who were administered prophylaxis with a conventional mechanical procedure alone, and those who were administered pharmacological anticoagulation therapy. Therefore, the optimum methods of prophylaxis are still controversial. The purpose of this study was to investigate whether manual calf massage and passive ankle motion could lower the risk for venous thromboembolism after total hip arthroplasty. We retrospectively reviewed the data of 126 consecutive patients undergoing elective primary unilateral total hip arthroplasty wherein manual calf massage and passive ankle motion were performed after the surgery at our hospitals between January and October 2014. The 138 patients of the control group underwent total hip arthroplasty using the same surgical approach and pre- and postoperative protocols without this mechanical prophylaxis between January and December 2013. This mechanical prophylaxis was performed simultaneously 30 times during approximately 10 s; these procedures were repeated thrice immediately after total hip arthroplasty. Duplex ultrasonography was performed to observe the veins of both legs in all the patients on postoperative day 7. The incidence of deep vein thrombosis was 6.52% and 0.79% in the control and manual calf massage and passive ankle motion groups, respectively. The odds ratio for the manual calf massage and passive ankle motion groups was 8.72. Performing this mechanical prophylaxis reduced the incidence of venous thromboembolism after total hip arthroplasty. This mechanical prophylaxis is not only simple and easy, but is also safe and inexpensive. We therefore recommend that manual calf massage and passive ankle motion be performed in patients who will undergo total hip

Many studies have found acute gastrointestinal infections to be among the most likely reason for clinic visits among forward deployed soldiers and are considered a significant contributor to morbidity in this population. This occurs despite the controlled food and water distribution systems under which military populations operate. Furthermore, recent studies have indicated that providers often fail to appropriately identify and treat the typical causes of these infections. To adequately address this issue, an assessment of gaps in knowledge, practice, and management of acute diarrhea in deployed troops was conducted. A multiple-choice survey was developed by clinical researchers with expertise in travelers' diarrhea (TD) and provided to a convenience sample of clinical providers with a broad range of training and operational experience. The survey evaluated provider's knowledge of TD along with their ability to identify etiologies of various syndromic categories of acute gastrointestinal infections. Providers were also queried on selection of treatment approaches to a variety of clinical-based scenarios. A total of 117 respondents completed the survey. Most were aware of the standard definition of TD (77%); however, their knowledge about the epidemiology was lower, with less than 24% correctly answering questions on etiology of diarrhea, and 31% believing that a viral pathogen was the primary cause of watery diarrhea during deployment. Evaluation of scenario-based responses showed that 64% of providers chose not to use antibiotics to treat moderate TD. Furthermore, 19% of providers felt that severe inflammatory diarrhea was best treated with hydration only while 25% felt hydration was the therapy of choice for dysentery. Across all provider types, three practitioner characteristics appeared to be related to better scores on responses to the nine management scenarios: having a Doctor of Medicine or Doctor of Osteopathy degree, greater knowledge of TD epidemiology

Objective: To determine the value of 3.0 T contrast-enhanced MR angiography (CE-MRA) with simultaneous calf compression in demonstrating and diagnosing diabetic peripheral vascular disease. Methods: Sixth-one patients with type 2 diabetes mellitus complicating vascular disease of lower limb were enrolled in this study. The patients included 37 males and 24 females with a mean age of (70±7.65) years. The mean duration of disease was (11.6±6.0) years. The patients were randomly divided into compression group (n=31) and conventional group (n=30). CE-MRA with a 3.0 T MR unit was performed in all patients. During CE-MRA, calf compression with a cuff was simultaneously applied to patients of compression group. DSA, which was regarded as gold standard, was conducted within one week after the procedure. The quality of MRA images was separately evaluated by two radiologists, the results were compared between two groups. Results: Taking DSA findings as reference, the image quality of calf and foot in compression group was much better than that in conventional group (P 50% arterial stenosis or occlusion of leg the image in compression group was also better than that in conventional group (P<0.05). CE-MRA with simultaneous calf compression could significantly eliminate the overlapping venous shadow (P<0.05). Conclusion: The 3.0 T CE-MRA with simultaneous calf compression is a simple and practical technique, it can markedly improve the image quality as well as the diagnostic accuracy of peripheral vascular disease of lower limb in diabetic patients.

Eight 4-ha mixed warm-season grass pastures in southwestern Arkansas (33°40'4″ N, 93°35'24″ W, and elevation 107 m) were stocked with either large mature size (571 kg [SD 55.2] BW) or small mature size (463 kg [SD 58.2] BW) spring-calving cows at 4 stocking rates (SR; 1, 1.5, 2, or 2.5 cow-calf pairs/ha) over 4 yr to test the effects of SR and mature body size on cow and calf performance and system economics. Each pasture received 112 kg/ha N as ammonium nitrate in May and was broadcast seeded to annual ryegrass ( Lam.) in mid October each fall along with 112 kg/ha N as ammonium nitrate. Data were analyzed by regression to determine the effects of cow size and SR on calf performance, cow BW change, calf gain, weaning weight per hectare, hay feeding requirements, and net returns. As SR increased, cow BW and BCS at weaning decreased ( cow stocked per hectare ( = 0.44). Calf BW at weaning in October increased ( cow BW but was not affected ( = 0.66) by SR. As cow BW increased, calf BW at weaning per 100 kg cow BW decreased ( cow BW but was not affected ( = 0.44) by SR. Neither cow BW nor SR affected ( ≥ 0.53) pregnancy percentage, which averaged 88% over the 4-yr experiment. Calf BW weaned per hectare was not affected ( = 0.75) by cow BW but linearly increased ( cow per hectare SR. Hay feeding days and cost of hay per cow increased ( ≤ 0.05) and kilograms of hay offered per cow tended ( = 0.09) to linearly increase with increasing SR, yet cow BW had no effects ( > 0.22). Although there were no effects ( ≥ 0.38) of cow BW on carrying cost or net returns, increasing SR decreased ( cow and increased net returns by $70/cow and $438/ha for each cow per hectare increase in SR. These data indicate that increasing cow size can increase weaning BW of calves but does not affect total production per hectare or profitability, even though weaning weight efficiency ratios were reduced. Increasing SR reduced cow BW and BCS at weaning and increased feeding of conserved

Objectives. We investigated whether deep tube wells installed to provide arsenic-free groundwater in rural Bangladesh have the added benefit of reducing childhood diarrheal disease incidence. Methods. We recorded cases of diarrhea in children younger than 5 years in 142 villages of Matlab, Bangladesh, during monthly community health surveys in 2005 and 2006. We surveyed the location and depth of 12 018 tube wells and integrated these data with diarrhea data and other data in a geographic information system. We fit a longitudinal logistic regression model to measure the relationship between childhood diarrhea and deep tube well use. We controlled for maternal education, family wealth, year, and distance to a deep tube well. Results. Household clusters assumed to be using deep tube wells were 48.7% (95% confidence interval = 27.8%, 63.5%) less likely to have a case of childhood diarrhea than were other household clusters. Conclusions. Increased access to deep tube wells may provide dual benefits to vulnerable populations in Matlab, Bangladesh, by reducing the risk of childhood diarrheal disease and decreasing exposure to naturally occurring arsenic in groundwater.

Rotavirus infections are a major cause of diarrhea in children in both developed and developing countries. Rotavirus genetics, patient immunity, and environmental factors are thought to be related to the severity of acute diarrhea due to rotavirus in infants and young children. The objective of this study was to provide a correlation between rotavirus genotypes, clinical factors and degree of severity of acute diarrhea in children under 5 years old in Surabaya, Indonesia. A cross-sectional study was conducted in children aged 1-60 months with acute diarrhea hospitalized in Soetomo Hospital, Surabaya, Indonesia from April to December 2013. Rotavirus in stool specimens was identified by ELISA and genotyping (G-type and P-type) using multiplex reverse transcription PCR. Severity was measured using the Ruuska and Vesikari scoring system. The clinical factors were investigated included patient's age (months), hydration, antibiotic administration, nutritional state, co-bacterial infection and co-viral infection. A total of 88 children met the criteria; 80.7% were aged 6-24 months, watery diarrhea was the most common type (77.3%) and 73.6% of the subjects were co-infected with bacteria, of which pathogenic Escherichia coli was the most common (42.5%). The predominant VP7 genotyping (G-type) was G2 (31.8%) and that of VP4 genotyping (P-type) was P[4] (31.8%). The predominant rotavirus genotype was G2P[4] (19.3%); G1P[4] and G9P[4] were uncommon with a prevalence of 4.5%. There were significant differences between the common genotype and uncommon genotype with respect to the total severity score of diarrhea (p 10 times a day) (p = 0.045) in univariate analyses, but there was no significant correlation between P typing and severity of diarrhea. For combination genotyping of G and P, G2P[4] was significantly correlated with severe diarrhea in multivariate analyses (p = 0.029). There is a correlation between rotavirus genotype and severity of acute diarrhea in

The medical files of all neonates weighing ≤1500 g, born in Vali-e-Asr hospital (2001-2004 were studied. Two groups of neonates (living and dead were compared up to the time of hospital discharge or death. A total of 317 neonates were enrolled. A meaningful relationship existed between occurrence of death and low gestational age (P=0.02, low birth weight, lower than 1000 g (P=0.001, Apgar score <6 at 5th minutes (P=0.001, resuscitation at birth (P=0.001, respiratory distress syndrome (P=0.001 need for mechanical ventilation (P=0.001, neurological complications (P=0.001 and intraventricular hemorrhage (P=0.001. Regression analysis indicated that each 250 g weight increase up to 1250 g had protective effect, and reduced mortality rate. The causes of death of those neonates weighting over 1250 g should be sought in factors other than weight. Survival rate was calculated to be 80.4% for neonates weighing more than 1000 g. The most important high risk factors affecting mortality of neonates are: low birth weight, need for resuscitation at birth, need for ventilator use and intraventricular hemorrhage.

Mellor, J. E.; Zimmerman, J.

Although evidence suggests that climate change will negatively impact water resources and hence diarrheal disease rates in the developing world, there is uncertainty surrounding prior studies. This is due to the complexity of the pathways by which climate impacts diarrhea rates making it difficult to develop interventions. Therefore, our goal was to develop a mechanistic systems approach that incorporates the complex climate, human, engineered and water systems to relate climate change to diarrhea rates under future climate scenarios.To do this, we developed an agent-based model (ABM). Our agents are households and children living in Hubli-Dharward, India. The model was informed with 15 months of weather, water quality, ethnographic and diarrhea incidence data. The model's front end is a stochastic weather simulator incorporating 15 global climate models to simulate rainfall and temperature. The water quality available to agents (residents) on a model "day" is a function of the simulated day's weather and is fully validated with field data. As with the field data, as the ambient temperature increases or it rains, the quality of water available to residents in the model deteriorates. The propensity for an resident to get diarrhea is calculated with an integrated Quantitative Microbial Risk Assessment model with uncertainty simulated with a bootstrap method. Other factors include hand-washing, improved water sources, household water treatment and improved sanitation.The benefits of our approach are as follows: Our mechanistic method allows us to develop scientifically derived adaptation strategies. We can quantitatively link climate scenarios with diarrhea incidence over long time periods. We can explore the complex climate and water system dynamics, rank risk factor importance, examine a broad range of scenarios and identify tipping points. Our approach is modular and expandable such that new datasets can be integrated to study climate impacts on a larger scale. Our

Clostridium difficile (C. difficile) is recognized as a frequent cause of antibiotic-associated diarrhea and colitis. The aim of this review is to establish the efficacy of antibiotic therapy for C. difficile-associated diarrhea (CDAD), to identify the most effective antibiotic treatment for CDAD in adults and to determine the need for stopping the causative antibiotic during therapy. MEDLINE (1966 to 2006), EMBASE (1980 to 2006), Cochrane Central Database of Controlled Trials and the Cochrane IBD Review Group Specialized Trials Register were searched using the following search terms: "pseudomembranous colitis and randomized trial"; "Clostridium difficile and randomized trial"; "antibiotic associated diarrhea and randomized trial". Only randomized, controlled trials assessing antibiotic treatment for CDAD were included in the review. Probiotic trials are excluded. The following outcomes were sought: initial resolution of diarrhea; initial conversion of stool to C. difficile cytotoxin and/or stool culture negative; recurrence of diarrhea; recurrence of fecal C. difficile cytotoxin and/or positive stool culture; patient response to cessation of prior antibiotic therapy; sepsis; emergent surgery: fecal diversion or colectomy; and death. Data were analyzed using the MetaView statistical package in Review Manager. For dichotomous outcomes, relative risks (RR) and 95% confidence intervals (CI) were derived from each study. When appropriate, the results of included studies were combined for each outcome. For dichotomous outcomes, pooled RR and 95% CI were calculated using a fixed effect model, except where significant heterogeneity was detected, at which time the random effects model was used. Data heterogeneity was calculated using MetaView. Twelve studies (total of 1157 participants) involving patients with diarrhea who recently received antibiotics for an infection other than C. difficile were included. The definition of diarrhea ranged from at least two loose stools

A Randomized, open labeled, clinical controlled trial in a tertiary care hospital outpatient department (OPD) and emergency department. Participants were one hundred and seventeen children without any chronic illness between 2 and 5 years presenting to OPD, having acute watery diarrhea for <48 h with mild to moderate dehydration, not on antibiotics and requiring oral rehydration therapy. Intervention done was DS with a dose of 1.5 g thrice daily. Freshly dissolved DS in a dose of 1.5 g thrice daily for 5 days significantly shortened the duration of acute watery diarrhea in children aged 2-5 years. There were no adverse effects on the use of DS. DS was acceptable to the children, and its administration was not accompanied with any side effects. DS reduces the duration of diarrhea in Indian children and prevents a prolonged course, and therefore, may consistently reduce the costs in treatment of acute watery diarrhea.

Acute diarrheal illness constitutes a major cause of morbidity and mortality in children in developing countries. Most of the complications of diarrhea occur due to excessive fluid and electrolyte loss; adverse complications are seen more with increasing severity of dehydration. This study was conducted to identify the relation of renal function and electrolyte abnormalities in children with varying severity of dehydration. This study was carried out in Manipal Teaching Hospital, Pokhara, Nepal over duration of one year. The aims were to find out the association of renal function and electrolyte disturbances with type of diarrhea, severity of dehydration and their relation to outcome. All children more than one month and less than 15 years with acute diarrhea were included in the study. Data were entered and analyzed by SPSS version 19. Statistical analysis applied was Chi-square test. A p-value of Dehydration was associated more with Acute Watery Diarrhea than with Invasive Diarrhea. Renal function and electrolyte abnormalities were seen more in Acute Watery Diarrhea with increasing levels of blood urea, serum creatinine and abnormal levels of serum sodium seen with increased severity of dehydration. Abnormalities in renal function and electrolytes correlated significantly with severity of dehydration. The outcome of patients correlated with severity of dehydration with mortality occurring in 18.1% of patients with Severe dehydration, 0.8% of Some dehydration with no mortality in the No dehydration group.

To find out the effect of Rifixamin in patients of irritable bowel syndrome with predominant diarrhea. Material and methods.: This study was carried out from January 2012 to September 2012 on patients presenting to medical OPD of Mayo Hospital, Lahore. Study design: It is descriptive type of study. Result: Out of 30 patients presenting to medical OPD with diagnosis of diarrhea predominant irritable bowel syndrome 18 (60%) were females and 12 (40 %) were males. The age of the patients were between 13-38 years. All the patients were prescribed Tab. Rifaximin 550 mg three times a day for 14 days and were assessed for their complaints like diarrhea its frequency and consistency using 5 point scale for stool consistency, abdominal pain and abdominal bloating using Li Kert scoring. The patients were assessed for their complaints on day 15 and again after 2 months. It was found out that out of 30 patients 18 (60%), patients showed improvement in their global symptoms of irritable bowel syndrome at 15 day of follow up, but at 2 months of follow up out of 18 (60%) patients who responded to Rifaximin treatment at 15 day only 12 (40%) patients reported to have consistent improvement in symptoms while 6 (20%) patients again developed, diarrhea abdominal pain and bloating 2 (6%) patients left the study at 3rd day of treatment due to increase in frequency of diarrhea. It was observed that drug was more effective in females and older individuals. Out of 18 patients who responded 11 (61%)were females and the patients were of relatively of older age. Conclusion: It was found out that treatment with Rifaximin provided significant relief of IBS symptoms, bloating abdominal pain and diarrhea. (author)

Globally, diarrhea remains a leading killer of young children. In Sierra Leone, one in seven children die before their fifth birthday and diarrhea is a leading cause. Studies that emphasize the demand-side of health interventions -- how caregivers understand causation and prevention of diarrhea -- have been neglected in research and programming. We undertook applied qualitative research including 68 in-depth interviews and 36 focus group discussions with mothers, fathers and older female caretakers to examine the causes and prevention of childhood diarrhea in villages near and far from health facilities across four rural districts. Verbal consent was obtained. Respondents reported multiple, co-existing descriptions of causation including: contaminated water and difficulties accessing clean water; exposure to an unclean environment and poor food hygiene; contaminated breast milk due to sexual intercourse, overheated breast milk or bodily maternal conditions such as menstruation or pregnancy; and dietary imbalances and curses. Respondents rarely discussed the role of open defecation or the importance of handwashing with soap in preventing diarrhea. Categorizing behaviors as beneficial, harmful, non-existent or benign enables tailored programmatic recommendations. For example, respondents recognized the value of clean water and we correspondingly recommend interventions that reinforce consumption of and access to clean water. Second, respondents report denying "contaminated" breast milk to breastfeeding children. This is a harmful practice that merits attention. Third, the role of open defecation and poor hygiene in causing diarrhea is less understood and warrants introduction or clarification. Finally, the role of exposed feet or curses in causing diarrhea is relatively benign and does not necessitate programmatic attention. Further research supportive of communication and social mobilization strategies building on these findings is required to ensure that improved

Under the strategy, community units (CUs were established as level one of the Kenyan health system. A core member at this level is the community health worker (CHW. The objective of this study was to assess the relationship among the performance of the CUs, the prevalence of childhood diarrhea and appropriate treatment for it by controlling individual and community-level factors. Methods The main dataset used in this study was the 2011 Nyanza Province county-based Multiple Indicator Cluster Survey (MICS. In addition, based on the list of community units in Nyanza Province, Kenya, we identified the area’s CUs and their performance. MICS data and data on CUs were merged using sub-location names. There were 17 individual and two community-level independent variables in this study. Bivariate analysis and a multilevel logistic regression were performed. Results Factors significantly associated with a lower prevalence of diarrhea among children under five were the child’s increasing age, middle-aged household heads, children who received more attention, water treatment and rural versus urban area residence, while male children and highly performing CUs were significantly associated with a higher prevalence of diarrhea. In addition, middle wealth index, severity of diarrhea and middle- and high-CU performance were significantly associated with appropriate treatment for childhood diarrhea. Conclusions Although this study found that children living in areas of high CU performance were more likely to have diarrhea, these areas would have been identified as being more at risk for diarrhea prevalence and other health concerns, prioritized for the establishment of a CU and allocated more resources to improve the performance of CUs. A higher CU performance was significantly associated with the appropriate

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

Neonates born to opioid-maintained mothers are at risk of developing neonatal abstinence syndrome (NAS), which often requires pharmacological treatment. This study examined the effect of opioid maintenance treatment on the incidence and timing of NAS, and compared two different NAS treatments (phenobarbital versus morphine hydrochloride). Fifty-three neonates born to opioid-maintained mothers were included in this study. The mothers received methadone (n=22), slow-release oral morphine (n=17) or buprenorphine (n=14) throughout pregnancy. Irrespective of maintenance treatment, all neonates showed APGAR scores comparable to infants of non-opioid dependent mothers. No difference was found between the three maintenance groups regarding neonatal weight, length or head circumference. Sixty percent (n=32) of neonates required treatment for NAS [68% in the methadone-maintained group (n=15), 82% in the morphine-maintained group (n=14), and 21% in the buprenorphine-maintained group (n=3)]. The mean duration from birth to requirement of NAS treatment was 33 h for the morphine-maintained group, 34 h for the buprenorphine-maintained group and 58 h for the methadone-maintained group. In neonates requiring NAS treatment, those receiving morphine required a significantly shorter mean duration of treatment (9.9 days) versus those treated with phenobarbital (17.7 days). Results suggest that morphine hydrochloride is preferable for neonates suffering NAS due to opioid withdrawal.

Previous studies have determined that stress causes decreases in feed intake and efficiency in livestock, but the effect of repeated transport on these parameters has not been well studied. This study determined how repeated transport affected calf post-transport behavior, feed intake, ADG, and feed conversion. Thirty-six 4-mo-old Holstein steer calves were housed in groups of 6 with each group randomly assigned to either transport or control treatments. Each calf was assigned to an individual Calan gate feeder and feed intake was recorded daily. Transport calves were transported for 6 h in their groups in a 7.3 by 2.4 m gooseneck trailer divided into 3 compartments, at an average density of 0.87 m/calf, every 7 d for 5 consecutive weeks. After return to their home pens, behavior was recorded for transported calves at 5-min intervals for 1 h. Calf ADG and feed conversion were analyzed in a mixed model ANOVA, whereas feed intake was analyzed as a repeated measure in a mixed model ANOVA. Post-transport, calves followed a pattern of drinking, eating, and then lying down. The highest (82 ± 5% calves) and lowest (0 ± 5% calves) incidences of eating behavior occurred 10 and 60 min post-transport, respectively. Control calves had a higher feed intake than transported calves overall (7.29 ± 0.22 kg for control and 6.91 ± 0.21 kg for transport; = 0.01), for the feeding posttreatment (6.78 ± 0.27 kg for control and 6.01 ± 0.28 kg for transport; = 0.007), and the day after treatment (7.83 ± 0.23 kg for control and 7.08 ± 0.15 kg for transport; = 0.02). Feed intake for the feeding post-transport for transport calves significantly decreased after the second transport but increased with each successive transport ( < 0.0001). Overall, control calves had higher ADG than transported calves (1.34 ± 0.13 kg/d for control and 1.15 ± 0.12 kg/d for transport; = 0.006). No significant difference ( = 0.12) between treatments was detected for feed conversion. These results

Diarrhea is an important problem among the under-five children in India. The paper examines long-term impacts of recurrent floods on diarrhea among under-five children in Uttar Pradesh, India. A two stage stratified cluster survey was conducted in flood affected (exposed) and non-flood affected areas (unexposed). The long-term impact of the floods was not clearly marked in the overall prevalence of diarrhea with the exposed group having prevalence of 55.1% as against 56.2% in the unexposed group of children under five. Economic condition of the household is associated with the prevalence of diarrhea in both exposed and unexposed strata. Anemia was found to be a significant risk factor for diarrhea among children in both the flood exposed and non-flood exposed populations. The recurrent floods did not have any significant effect on the prevalence of diarrhea in relation to gender, religion, caste, and household size. The study indicates that the long-term impacts of floods are very differently manifested than the immediate impacts.

Background: A previous study suggested that U.S. students who lived in Mexico for 1 year had a risk of diarrhea intermediate between the rate for newly arrived U.S. students and Mexican students; however, the study was not controlled for changes of risky behavior over time. Methods: An analysis of acute diarrhea occurring among U.S. and Mexican student groups living in Guadalajara, Mexico was conducted to explore the association of diarrhea developing during selected 28-day periods with length of residence, season, and risk factors such as locations of food consumption, consumption of tap water, unsafe ice, alcohol, and antibiotics. Results: Compared to U.S. and Mexican student groups, newly arrived U.S. college students in July had the highest rate of diarrhea (55%), highest enteropathogen isolation rate (46%), and most consumption of alcohol and antibiotics; they also ate most frequently at restaurants and in Mexican family homes. Compared to a 34% rate of diarrhea among newly arrived U.S. medical students in August, the rate was only 6% among established medical students in January. This drop in attack rate was attended by less tap water and unsafe ice consumption by established students in January compared to the habits of newly arrived students in January or August when risky behavior was otherwise similar among these groups. The role of tap water and unsafe ice in the acquisition of wintertime diarrhea is further supported by the relatively high 29% rate of diarrhea among U.S. medical students newly arrived in January, who also consumed more tap water and ice than established students in January. Enterotoxigenic E. coli disease was observed only during the summer months; whereas, Campylobacter jejuni disease and disease associated with no detected pathogen were more common in winter. Conclusions: These data imply that wintertime diarrhea in Guadalajara is more likely than summertime diarrhea to be waterborne and to be caused by agents such as viruses or

Oral Administration of Astrovirus Capsid Protein Is Sufficient To Induce Acute Diarrhea In Vivo

Directory of Open Access Journals (Sweden)

Victoria A. Meliopoulos

Full Text Available The disease mechanisms associated with the onset of astrovirus diarrhea are unknown. Unlike other enteric virus infections, astrovirus infection is not associated with an inflammatory response or cellular damage. In vitro studies in differentiated Caco-2 cells demonstrated that human astrovirus serotype 1 (HAstV-1 capsid protein alone disrupts the actin cytoskeleton and tight junction complex, leading to increased epithelial barrier permeability. In this study, we show that oral administration of purified recombinant turkey astrovirus 2 (TAstV-2 capsid protein results in acute diarrhea in a dose- and time-dependent manner in turkey poults. Similarly to that induced by infectious virus, TAstV-2 capsid-induced diarrhea was independent of inflammation or histological changes but was associated with increased intestinal barrier permeability, as well as redistribution of sodium hydrogen exchanger 3 (NHE3 from the membrane to the cytoplasm of the intestinal epithelium. Unlike other viral enterotoxins that have been identified, astrovirus capsid induces diarrhea after oral administration, reproducing the natural route of infection and demonstrating that ingestion of intact noninfectious capsid protein may be sufficient to provoke acute diarrhea. Based on these data, we hypothesize that the astrovirus capsid acts like an enterotoxin and induces intestinal epithelial barrier dysfunction.

Purpose: During adjuvant radiotherapy (RT) for rectal cancer, patients receiving 5-fluorouracil (5-FU) by protracted venous infusion have a higher risk of diarrhea than have patients receiving bolus 5-FU. Toxicity from a previously reported randomized clinical trial was analyzed to quantify the difference in this risk. Additionally, the persistence of diarrhea after RT was analyzed. Methods and Materials: A total of 656 patients were eligible. Patients with T3-4 N0-2 M0 or T1-2 N1-2 M0 resected, high-risk rectal cancer were randomly allocated to receive 5-FU by either protracted venous infusion or bolus during RT (50.4-54.0 Gy). Two cycles of bolus 5-FU were given before and after RT. One-half of the first 445 patients were also randomly allocated to receive lomustine in conjunction with the bolus 5-FU. The incidence and severity of diarrhea in relation to patient and treatment characteristics were evaluated. Results: The rate of diarrhea was significantly greater in patients receiving 5-FU by protracted venous infusion than in patients receiving bolus 5-FU; the difference was most pronounced for Grade 3 (severe) diarrhea (21% versus 13%, p=0.007). The incidence and magnitude of diarrhea before and after RT were similar. Patients treated with an anterior resection had a higher rate of severe or life-threatening diarrhea than did patients treated with an abdominoperineal resection (31% vs. 12%, p<0.001). Conclusions: During pelvic RT, patients who receive 5-FU by protracted venous infusion rather than by bolus have a higher risk of severe or life-threatening diarrhea during RT. This risk does not appear to persist during chemotherapy after completion of pelvic RT
