Abstract
Quantifying the water and mineral losses in feces is essential to determine the optimal composition of oral rehydration solutions (ORS) for diarrheic animals. In a randomized complete block design, this study evaluated water, mineral, and blood acid-base balance of calves with naturally occurring diarrhea receiving ORS or a placebo. On d 0, 45 calves (age: 18 ± 3.2 d; mean ± SD) were selected based on the presence of visual signs of diarrhea, such as dirty tail or wet feces, along with clinical symptoms evaluated by measuring the skin turgor and the degree of enophthalmos. On d 1, calves were divided into blocks of 3 animals based on blood base excess (BE) measured at 0900 h, and within each block, calves were randomly assigned to 1 of 3 treatments (15 calves per treatment) including (1) a hypertonic ORS (HYPER; Na+ = 110 mmol/L; 370 mOsm/kg; strong ion difference [SID] = 60 mEq/L), (2) a hypotonic ORS with low Na+ (HYPO; Na+ = 77 mmol/L; 278 mOsm/kg; SID = 71 mEq/L), and (3) a placebo consisting of lukewarm water with 5 g/L of whey powder (CON). Milk replacer (MR) was fed through teat buckets twice daily at 0630 h and 1700 h in 2 equally sized meals of 2.5 L from d 1 to 3 and of 3.0 L on d 4 and 5. Treatments consisting of 2.0 L lukewarm solutions were administered between milk meals from d 1 to 3 at 1200 h and 2030 h through teat buckets. Refusals of MR and treatments were recorded daily, and blood samples were collected from the jugular vein once daily at arrival in the afternoon of d 0 and at 0900 h from d 1 to 5 after arrival. Urine and feces were collected quantitatively over a 48-h period from 1200 h on d 1 to 1200 h on d 3, and a representative sample of each 24-h period was stored. In addition, the volume of extracellular fluid was evaluated on d 2 by postprandial sampling over a 4-h period relative to the injection of sodium thiosulfate at 1300 h. Total daily fluid intake (MR, treatment, and water) from d 1 to 3 was greater in HYPER (LSM ± SEM; 8.9 ± 0.36 L/d) and HYPO (7.8 ± 0.34 L/d) than in CON (6.6 ± 0.34 L/d). This resulted in a greater water balance (water intake - fluid output in urine and feces) in calves receiving ORS (59.6 ± 6.28 g/kg BW per 24 h vs. 39.6 ± 6.08 g/kg BW per 24 h). Fecal Na+ losses were greater in HYPER than in the other treatments (81 ± 12.0 mg/kg BW per 24 h vs. 24 ± 11.8 mg/kg BW per 24 h). Blood pH was higher in HYPO (7.41 ± 0.016) than CON (7.35 ± 0.016) over the 5 monitoring days, whereas HYPER (7.37 ± 0.017) did not differ with other treatments. In this experimental model, diarrheic calves were likely unable to absorb the high Na+ load from HYPER, resulting in greater Na+ losses in feces, which might have impaired the alkalinizing capacity of HYPER. In contrast, HYPO significantly sustained blood acid-base balance compared with CON, whereas HYPER did not. This suggests that low tonicity ORS with a high SID are more suitable for diarrheic calves.

Abstract
Characteristics of the use of two oral rehydration solutions [rice-based gruel (RBG) or oral rehydration salts (ORS)] were assessed in 162 mothers of children under five years of age who presented a first episode of diarrhoea during the study period, in 12 rural villages of Central Mexico. Eighty-six mothers lived in six villages randomly assigned to receive the RBG promotion and 76 lived in six villages assigned to receive the ORS promotion. The intervention strategy, relying on face-to face contact by health auxiliaries who teach mothers about the dangers of dehydration, how to recognize it, and how to prepare and feed an oral rehydration solution, closely resembled that used by the National Program for the Control of Diarrheal Diseases. Before the intervention, 42% of all mothers used RBG and 58% used ORS; 8% of mothers who used RBG and 18% of those who used ORS used the beverage for rehydration purposes. After the intervention, in the villages where RBG was promoted, 57 (66%) of the mothers used RBG and 14 (16%) used ORS. In the villages where ORS was promoted, 9 (12%) of the mothers used RBG and 58 (76%) used ORS. In both groups, all mothers used at least one other beverage (usually herbal tea) during diarrhoea. but the promoted beverages were used first The use of the promoted beverage was higher when mothers had used it before the intervention. Eighty-six percent of mothers who prepared RBG used the promoted concentration of ingredients, whereas all mothers who prepared ORS correctly diluted one package in 1 L of water. After the intervention, 54% and 67% of mothers said they used RBG and ORS specifically to prevent dehydration.

Abstract
BACKGROUND Acute diarrhoea is one of the main causes of morbidity and mortality among children in low-income countries. Glucose-based oral rehydration solution (ORS) helps replace fluid and prevent further dehydration from acute diarrhoea. Since 2004, the World Health Organization (WHO) has recommended the osmolarity of less than 270 mOsm/L (ORS ≤ 270) versus greater than 310 mOsm/L formulation (ORS ≥ 310). Polymer-based ORS (for example, prepared using rice or wheat) slowly releases glucose and may be superior to glucose-based ORS. OBJECTIVES To compare polymer-based oral rehydration solution (polymer-based ORS) with glucose-based oral rehydration solution (glucose-based ORS) for treating acute watery diarrhoea. SEARCH METHODS We searched the following sources up to 5 September 2016: the Cochrane Infectious Diseases Group (CIDG) Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2016, Issue 9), MEDLINE (1966 to 5 September 2016), EMBASE (1974 to 5 September 2016), LILACS (1982 to 5 September 2016), and mRCT (2007 to 5 September 2016). We also contacted researchers, organizations, and pharmaceutical companies, and searched reference lists. SELECTION CRITERIA We included randomized controlled trials (RCTs) of people with acute watery diarrhoea (cholera and non-cholera associated) that compared polymer-based and glucose-based ORS (with identical electrolyte contents). DATA COLLECTION AND ANALYSIS Two review authors independently assessed the search results and risk of bias, and extracted data. In multiple-treatment arms with two or more treatment groups, we combined outcomes as appropriate and compared collectively with the control group. MAIN RESULTS Thirty-five trials that included 4284 participants met the inclusion criteria: 28 trials exclusively included children, five included adults, and two included both adults and children. Polymer-based ORS versus glucose-based ORS (osmolarity ≤ 270) Eight trials (752 participants) evaluated this comparison, and seven trials used rice as a polymer source. Polymer-based ORS may decrease mean stool output in the first 24 hours by 24 mL/kg (mean difference (MD) -24.60 mL/kg, 95% CI -40.69 to -8.51; one trial, 99 participants, low quality evidence). The average duration of diarrhoea may be reduced by eight hours (MD -8.24 hours, 95% CI -13.17 to -3.30; I² statistic = 86%, five trials, 364 participants, low quality evidence) with polymer ORS but results are heterogeneous. Limited trials showed no observed difference in the risk of unscheduled use of intravenous fluid (RR 0.66, 95% CI 0.43 to 1.02; I² statistic = 30%; four trials, 376 participants, very low quality evidence), vomiting (very low quality evidence), and hyponatraemia (very low quality evidence). Polymer-based ORS versus glucose-based ORS (osmolarity ≥ 310) Twenty-seven trials (3532 participants) evaluated this comparison using a variety of polymers. On average, polymer ORS may reduce the total stool output in the first 24 hours by around 65 mL/kg (MD -65.47 mL/kg, 95% CI -83.92 to -47.03; 16 trials, 1483 participants, low quality evidence), and may reduce the duration of diarrhoea by around eight hours (MD -8.57 hours; SD -13.17 to -4.03; 16 trials, 1137 participants, low quality evidence) with substantial heterogeneity. The proportion of participants that required intravenous hydration was low in most trials with fewer in the polymer ORS group (RR 0.75, 95% CI 0.57 to 0.98; 19 trials, 1877 participant, low quality evidence) . Subgroup analysis by type of pathogen suggested an effect on unscheduled intravenous fluid in those infected with mixed pathogens (RR 0.63, 95% CI 0.41 to 0.96; 11 trials, 928 participants, low quality evidence), but not in participants positive for Vibrio cholerae (RR 0.94, 95% CI 0.66 to 1.34; 7 trials, 535 participants, low quality evidence). No difference was observed in the number of patients who developed vomiting (RR 0.91, 95% CI 0.72 to 1.14; 10 trials, 584 participants, very low quality evidence), hyponatraemia (RR 1.82, 95% CI 0.52 to 6.44; 4 trials, 385 participants, very low quality evidence), hypokalaemia (RR 1.29, 95% CI 0.74 to 2.25; 2 trials, 260 participants, low quality evidence), or persistent diarrhoea (RR 1.28, 95% CI 0.68 to 2.41; 2 trials, 885 participants, very low quality evidence). AUTHORS' CONCLUSIONS Polymer-based ORS shows advantages compared to glucose-based ORS (at ≥ 310 mOsm/L). Comparisons favoured polymer-based ORS over ORS ≤ 270 but analysis was underpowered.

Abstract
Oral rehydration solution (ORS) was established as the cornerstone of therapy for dehydration secondary to acute infectious diarrhea approximately 40 years ago. The efficacy of ORS is based on the ability of glucose to stimulate Na and fluid absorption in the small intestine via a cyclic AMP-independent process. Despite the establishment that ORS is the primary reason for the substantial reduction in morbidity and mortality from diarrhea in children in developing countries, the use of ORS has lagged for many reasons. This review highlights efforts to establish a major reformulation of ORS following the demonstration that short-chain fatty acids (SCFA) stimulate colonic Na and fluid absorption by a cyclic AMP-independent mechanism. The addition of high-amylose maize starch (HAMS), a microbially-fermentable (or 'resistant') starch, to ORS results in delivery of non-absorbed carbohydrate to the colon where it is fermented to SCFA. To date, three randomized controlled trials with a HAMS-ORS in south India have demonstrated a substantial decrease in diarrhea duration in both adults and children hospitalized for acute diarrhea. Significant efforts are now underway to establish this dual-action, modified HAMS-hypoosmolar ORS solution as the standard ORS for the treatment of dehydration from acute diarrhea.

Abstract
Using dietary fibre to control childhood diarrhoea has rarely been discussed. However, dietary fibre is being proposed to prevent diarrhoea in piglets. The present study aimed to study the effects of introducing fibre in the post-weaning piglet diet and its particle size on the intestinal ecosystem before and after an experimental infection with Escherichia coli. A total of thirty-six post-weaning piglets were assigned to four experimental diets: a negative control (NC) diet, the same diet with 4 % wheat bran coarse (WBc) particle size or finely milled (WBF) and a positive control (PC) diet with an antibiotic. On day 9, animals were challenged with E. coli. Faecal and digesta samples were obtained before and after the experimental infection and changes in the microbial ecosystem were measured. Animals fed the WBc and the PC diets showed a significant reduction in the faecal score compared with the NC diet. The inclusion of WBc in the diet increased total volatile fatty acid concentration, reduced Bacteroidetes in the faeces before and after the experimental infection compared with the NC diet and increased Firmicutes at the end of the experiment. Based on the results, diarrhoea scours and the composition of the pig gut microbial community are modified by the inclusion of a relatively small amount of wheat bran in the diet, being the physical presentation of the fibre a determinant of that difference.

BACKGROUND Acute diarrhoea is one of the principal causes of morbidity and mortality among children in low-income countries. Glucose-based ORS helps replace fluid and prevent further dehydration from acute diarrhoea. Since 2004, the World Health Organization has recommended the osmolarity < 270 mOsm/L (ORS </= 270 ) over the > 310 mOsm/L formulation (ORS >/= 310). Glucose polymer-based ORS (eg prepared using rice or wheat) slowly releases glucose and may be superior. OBJECTIVES To compare polymer-based ORS with glucose-based ORS for treating acute watery diarrhoea. SEARCH STRATEGY In September 2008, we searched the Cochrane Infectious Diseases Group Specialized Register, CENTRAL (The Cochrane Library 2008, Issue 3), MEDLINE, EMBASE, LILACS, and mRCT. We also contacted researchers, organizations, and pharmaceutical companies, and searched reference lists. SELECTION CRITERIA Randomized controlled trials of people with acute watery diarrhoea (cholera and non-cholera associated) comparing polymer-based and glucose-based ORS (with identical electrolyte contents). DATA COLLECTION AND ANALYSIS Two authors independently assessed the search results and risk of bias, and extracted data. In multiple treatment arms with two or more treatment groups, we combined outcomes as appropriate and compared collectively with the control group. MAIN RESULTS Thirty-four trials involving 4214 participants met the inclusion criteria: 27 in children, five in adults and two in both. Twelve trials used adequate methods to conceal allocation. Most compared polymer-based ORS with ORS >/= 310. There were fewer unscheduled intravenous infusions in the polymer-based ORS group compared with glucose-based ORS (ORS >/= 310 and </= 270 groups combined) (RR 0.75, 95% CI 0.59 to 0.95; 2235 participants, 19 trials). Adults positive for Vibrio cholerae had a shorter duration of diarrhoea with polymer-based ORS than with ORS </= 270 (MD -7.11 hours, SD -11.91 to -2.32; 228 participants, 4 trials). Wheat-based ORS resulted in lower total stool output in the first 24 hours compared with ORS </= 270 (MD -119.85 g/kg, SD -114.73 to -124.97; 129 participants, 2 trials). Adverse effects were similar for polymer-based ORS and glucose-based ORS. AUTHORS' CONCLUSIONS Polymer-based ORS shows some advantages compared to ORS >/= 310 for treating all-cause diarrhoea, and in diarrhoea caused by cholera. Comparisons favoured the polymer-based ORS over ORS </= 270, but the analysis was underpowered. If specialists consider a potential role for polymer-based ORS, further trials against the current standard (ORS </= 270) will be required.

Abstract
BACKGROUND Oral rehydration therapy is used to treat dehydration caused by diarrhoea. However the rehydration solution does not reduce stool loss or length of illness. A solution able to do this may lessen the use of ineffective diarrhoea treatments as well as improve morbidity and mortality related to diarrhoea. OBJECTIVES The objective of this review was to assess the effects of rice-based oral rehydration salts solution compared with glucose-based oral rehydration salts solution on reduction of stool output and duration of diarrhoea in patients with acute watery diarrhoea. SEARCH STRATEGY We searched the Cochrane Infectious Diseases Group trials register, the Cochrane Controlled Trials Register, Medline, Embase, Lilacs and the reference lists of relevant articles. We also contacted researchers in the field. SELECTION CRITERIA Randomized trials comparing standard World Health Organization oral rehydration solution with an experimental oral rehydration salts solution in which glucose (20 grams per litre) was replaced by 50-80 grams per litre of rice powder, with the electrolytes remaining unchanged. DATA COLLECTION AND ANALYSIS Data were extracted independently by a statistician and a clinician. MAIN RESULTS Twenty-two trials were included. Concealment of allocation was adequate in 15 of these trials. Irrespective of age, people with cholera who were given rice oral rehydration salts solution had substantially lower rates of stool loss than those given oral rehydration salts solution in the first 24 hours. Mean stool outputs in the first 24 hours were lower by 67 millilitres/kg of body weight (weighted mean difference -67.40, 95% confidence interval -94.26 to -41.53) in children, and by 51 millilitres/kg of body weight (weighted mean difference -51.07, 95% confidence interval -65.87 to -36.27) in adults. The rate of stool loss in infants and children with acute non-cholera diarrhoea was reduced by only four millilitres/kg of body weight (weighted mean difference -4.29, 95% confidence interval -9.36 to 0.78). AUTHORS' CONCLUSIONS Rice-based oral rehydration appears to be effective in reducing stool output in people with cholera. This effect was not apparent in infants and children with non-cholera diarrhoea.

Abstract
BACKGROUND Oral rehydration solution (ORS) for treatment of diarrhea relies on enhancement of small intestinal sodium and fluid absorption to correct dehydration. Amylase-resistant starch added to ORS significantly reduced the duration and severity of diarrhea in adults with cholera, presumably by generation of short-chain fatty acids in the colon and enhancement of colonic sodium and fluid absorption. The present study was initiated to determine whether addition of amylase-resistant starch to standard World Health Organization glucose-ORS (G-ORS) would reduce the duration of diarrhea and fecal fluid losses in children with acute diarrhea. METHODS One hundred eighty-three children (6 months to 3 years) with acute watery diarrhea were randomized to receive either standard treatment with G-ORS or G-ORS with additional amylase-resistant starch, HAMS (HAMS-ORS, 50g/L). Stool weight and consistency were monitored serially until development of formed stool or development of treatment failure defined as either the need for unscheduled intravenous fluid therapy or diarrhea longer than 72 hours. RESULTS Five of the subjects were lost to follow up. In 178 remaining children (87 HAMS-ORS and 91 G-ORS) with evaluable data, time from enrolment to last unformed stool was significantly less in children receiving HAMS-ORS (median, 6.75 hours; 95% confidence interval, 4.27-9.22) than in children treated with G-ORS (12.80 hours, 8.69-16.91) (P = 0.0292). Time to first formed stool was also significantly shorter in children receiving HAMS-ORS (median, 18.25 hours; 95% confidence interval, 13.09-23.41) compared with children receiving G-ORS (median, 21.50 hours; 95% confidence interval, 17.26-25.74) (P = 0.0440). The total amount of ORS consumed was similar in both groups. There was a trend toward lower mean stool weight in first 24 hours (P = 0.0752) as well as total diarrheal stool weight (P = 0.0926) in patients in the HAMS group compared with the G-ORS group. CONCLUSION In children with acute diarrhea, the addition of amylase-resistant starch to glucose ORS significantly shortened duration of diarrhea compared with standard treatment.

Abstract
We prospectively evaluated the incidence of difficulty in defecation in infants with gastroesophageal reflux who were treated with smaller volume feeds thickened with rice cereal and also assessed the effect of changing the cereal to oatmeal. We evaluated 53 thriving infants with uncomplicated gastroesophageal reflux who were treated with smaller volume feeds thickened with rice cereal. Parents maintained records of bowel movements for 7 days. Rice was substituted by oatmeal cereal in those infants developing difficulty in defecation and another 7 days' record was kept. Of the 53 infants enrolled, 34 (64%) reported no difficulty in defecation, 8 (15%) reported mild difficulty, and 11 (21%) reported severe difficulty in defecation during rice-based feedings. In these symptomatic 19 infants, after rice was substituted by oatmeal cereal, 10 infants (52.6%) reported no symptoms, 6 (31.6%) had mild symptoms, and 3 (15.8%) continued to have severe symptoms. We conclude that difficulty in defecation is common during treatment of infants with gastroesophageal reflux with smaller volume feeds thickened with rice cereal. Substitution of rice with oatmeal cereal results in partial or complete resolution of symptoms in most of these infants.

Abstract
BACKGROUND Although standard glucose-based oral rehydration therapy corrects the dehydration caused by cholera, it does not reduce the diarrhea. Short-chain fatty acids, which are produced in the colon from nonabsorbed carbohydrates, enhance sodium absorption. We conducted a study to determine the effects of an orally administered, nonabsorbed starch (i.e., one resistant to digestion by amylase) on fecal fluid loss and the duration of diarrhea in patients with cholera. METHODS We randomly assigned 48 adolescents and adults with cholera to treatment with standard oral rehydration therapy (16 patients), standard therapy and 50 g of rice flour per liter of oral rehydration solution (16 patients), or standard therapy and 50 g of high-amylose maize starch, an amylase-resistant starch, per liter of oral rehydration solution (16 patients). The primary end points were fecal weight (for every 12-hour period during the first 48 hours after enrollment) and the length of time to the first formed stool. RESULTS The mean (+/-SD) fecal weights in the periods 12 to 24 hours, 24 to 36 hours, and 36 to 48 hours after enrollment were significantly lower in the resistant-starch group (2206+/-1158 g, 1810+/-1018 g, and 985+/-668 g) than in the standard-therapy group (3251+/-766 g, 2621+/-1149 g, and 2498+/-1080 g; P=0.01, P= 0.04, and P=0.001, respectively). From 36 to 48 hours after enrollment, fecal weight was also significantly lower with the resistant-starch therapy than with the rice-flour therapy (985+/-668 g vs. 1790+/-866 g, P=0.01). The mean duration of diarrhea was significantly shorter with the resistant-starch therapy (56.7+/-18.6 hours) than with standard therapy alone (90.9+/-29.8 hours, P=0.001) or the rice-flour therapy (70.8+/-20.2 hours, P=0.05). Fecal excretion of starch was higher with the resistant-starch therapy (32.6+/-30.4) than with the standard therapy (11.7+/-4.1 g, P=0.002) or the rice-flour therapy (15.1+/-8.4 g, P=0.01). CONCLUSIONS The addition of a resistant starch to oral rehydration solution reduces fecal fluid loss and shortens the duration of diarrhea in adolescents and adults with cholera.

Abstract
Diarrhea is a common condition in neonatal calves and can be caused by a wide variety of infections and noxious agents. Oral electrolyte therapy is a simple and economical method of treating diarrheic calves. Oral electrolyte solutions can correct dehydration and acidosis, and they may also have a role in preventing or alleviating mucosal damage. Indications, the principles of administration, and choosing an electrolyte product are discussed with examples.

Abstract
Rice gruels have been used as home remedies to treat dehydration associated with diarrheal illness in developing countries. These preparations have produced conflicting results, most likely due to the heterogeneity of starch used. We investigated whether the modified tapioca starch, Textra (TX), at 5.0 or 10.0 g/L added to a 90 mmol/L Na+-111 mmol glucose oral rehydration solution (ORS) enhanced water and electrolyte absorption in two models of diarrhea. To induce a secretory state (model A), the jejunum of juvenile rats was perfused with 10 mmol/L theophylline (THEO) under anesthesia and then perfused with the solutions indicated above. To produce chronic osmotic-secretory diarrhea (model B), rats had a magnesium citrate-phenolphthalein solution as the sole fluid source for 1 wk, and then were perfused as the THEO-treated rats. Water, electrolyte, and glucose absorption were measured during both perfusions. As an extension of the perfusion studies, we compared how fast rats recovered from chronic osmotic diarrhea by offering them either water, ORS, or ORS containing 5.0 g/L TX along with solid food. Recovery rate markers were measured after 24 h and included weight gain, food and fluid intake, and stool output. In model A, addition of 5.0 g/L TX to ORS reversed Na+ secretion and improved net water as well as K+ and glucose absorption, compared with THEO-treated rats perfused with ORS without TX. In model B, addition of TX to ORS increased water, Na+, K+, and glucose absorption, compared with rats perfused without TX. Increasing TX from 5.0 to 10.0 g/L had no additional benefit. In recovery experiments, animals with free access to ORS with TX had significantly greater weight gain and decreased stool output compared with animals recovering with water or ORS without TX. Our experiments suggest that TX may be a useful additive to standard ORS to promote fluid and electrolyte absorption and may provide additional energy without increasing ORS osmotic load.

Abstract
Adequate nutritional intervention in diarrhoeal disease in children is crucial in obtaining optimal control of a disorder that may become life-threatening. During recent years, important advances have been made in our understanding of the pathophysiology of diarrhoeal states, in the formulation of oral rehydration solutions and in the role of micro- and macronutrients in diarrhoeal disorders. This chapter outlines some of the relevant concepts in the pathophysiology of diarrhoeal disease and provides a rationale for nutritional intervention. Guidelines for nutritional management in the settings of acute-onset diarrhoea, post-enteritis protracted diarrhoea and chronic non-specific diarrhoea are provided, mostly based on controlled clinical trials and meta-analyses of evidence-based medicine.

Abstract
BACKGROUND Partially hydrolyzed starches from staple cereals, obtained by heat or by enzymatic treatment, are often used in the formulation of homemade or extemporaneously used oral rehydration solutions used in developing countries. Conflicting or anecdotal results obtained thus far could be clarified with a standardized preparation tested under well-controlled laboratory conditions. METHODS A modified commercial tapioca starch was tested. Textra (National Starch and Chemical Co. Bridgewater, NJ, U.S.A.) added at 0, 5 or 10 g/l to an oral rehydration solution with 90 mM sodium and 111 mM glucose, in 30 rats malnourished by a protein-deficient diet for 3 weeks and in 26 well-fed control animals, using a one-pass jejunal perfusion. RESULTS In protein-deficient rats, Textra stimulated sodium absorption at 5 and 10 g/l (mean +/- SEM); 0 g/l Textra: 160 +/- 13 nmol/min x cm; 5 g/l Textra: 406 +/- 31 (p < 0.0001); and 10 g/l Textra 230 +/- 27 (p < 0.02). Potassium absorption was comparably increased. Textra also improved net water absorption and the water influx:efflux ratio. Glucose absorption was increased only at 10 g/l Textra. In control rats, Textra improved sodium and net water absorption at 5 g/l, but not at 10 g/l Textra; but the influx:efflux ratio and potassium absorption were unaltered. CONCLUSIONS These data, obtained in normal and protein-deficient rats, support the view that modified starch is a potentially useful, energy-rich additive for oral rehydration solution, which does not introduce an osmotic penalty.

Abstract
Many empirical clinical trials have used complex carbohydrate as substrate in oral rehydration solutions (ORSs) instead of glucose and have shown a number of important clinical benefits. Foremost among these are reduced stool volumes, shorter duration of diarrheal illness, and lower ORS intake. The underlying mechanisms to explain this clinical advantage have not been fully established, but a number of possible factors have been proposed: (1) increased substrate availability, (2) a "kinetic advantage" for glucose absorption by glucose polymer, (3) differential handling of glucose monomer and polymer by the small intestine, (4) low osmolality, (5) a separate effect of peptides and amino acids on solute-linked sodium absorption, (6) an antisecretory moiety in rice, and (6) enhanced mucosal repair and regeneration by luminal nutrients. In this report, we assess the relative contribution of these factors using evidence from laboratory-based studies, mainly in disease-related intestinal perfusion systems in animals and humans, and the relevant clinical studies available to date. We advance the hypothesis that of all the possible mechanisms proposed to underlie the enhanced clinical efficacy of complex carbohydrate ORSs, their hypotonicity plays the dominant role. If confirmed, this concept could guide future development of glucose and complex carbohydrate-based ORSs.

Abstract
BACKGROUND Glucose-based oral rehydration solutions (ORS) available in the United States do not appear to reduce the severity or duration of diarrhea. The use of cereal-derived ORS and cereal-based feedings appears to diminish the severity of illness in studies conducted in the developing world. To our knowledge, no controlled trials of cereal-derived ORS or cereal-based feedings have been performed in the United States. METHODS We performed a randomized, double-blind trial of two ORS feeding regimens in outpatients with diarrhea. Patients aged 2-13 months with acute watery diarrhea were enrolled. Subjects received standard glucose-based ORS in alternation with soy-based, lactose-free infant formula (Group 1) or rice syrup solid containing ORS in alternation with rice-based, lactose-free infant formula (Group 2). Subjects were visited at home daily to determine the severity of illness and characteristics of the stool. RESULTS After the first 2 days, significantly more Group 1 subjects continued to have diarrhea than did Group 2 subjects (median duration of diarrhea 3 vs. 2 days) as demonstrated by Kaplan-Meier survival curves (p = 0.04). CONCLUSION We conclude that infants fed a regimen consisting of rice syrup solid containing ORS and rice formula resolved their diarrhea sooner than did infants fed a regimen of standard glucose-based ORS and formula. The relative contributions of ORS and formula to this more rapid recovery can be elucidated by further studies.

Abstract
Glycerol (Gly) is a hydrophilic, absorbable, and energy-rich solute that could make water absorption more efficient. We investigated the use of Gly in a high-energy beverage containing corn syrup (CS) by using a small intestine perfusion procedure in the rat, an approach shown earlier to provide good preclinical information. The effectiveness of several formulations with Gly and CS was compared with commercial products and to experimental formulas where Gly substituted for glucose (Glc). The CS-Gly combination was more effective than preparations on the market containing sucrose and Glc-fructose syrups (G-P and G-L, respectively) in maintaining a net water absorption balance in the test jejunal segment [CS-Gly = 0.21 +/- 0.226, G-L = -1.516 +/- 0.467, and G-P = -0.299 +/- 0.106 (SE) microliter.min-1.cm-1 (P = 0.0113)] and in reducing sodium release into the lumen [CS-Gly = -133.2 +/- 16.2, G-L = -226.7 +/- 25.2, and G-P = -245.6 +/- 23.4 nmol.min-1.cm-1 (P = 0.0022)]. In other preparations, at equal CS concentrations (60 and 80 g/l, respectively), Gly clearly improved net water absorption over a comparable Glc-containing product [CS60-Gly = 0.422 +/- 0.136 and CS80-Gly = 0.666 +/- 0.378 vs. CS60-Glc = -0.282 +/- 0.200 and CS80-Glc = -1.046 +/- 0.480 microliters.min-1.cm-1 (P = 0.0019)]. On the basis of the data of this rat intestine perfusion model, Gly could be a useful ingredient in energy-rich beverages and might enhance fluid absorption in humans.

Abstract
A total of 326 Afghan children aged between 6 months and 5 years with uncomplicated nondysenteric diarrhea for the previous 24 h to 5 days were treated at home by their mothers with either wheat-salt solution (WSS) or World Health Organization recommended glucose-oral rehydration salts (G-ORS). For 7 consecutive days the children were examined in the household and the mothers interviewed to assess the progress, feeding practices, and perception of treatment efficacy. Children treated with WSS recovered significantly earlier; the mean duration on treatment was 4.0 days (SD 1.7 days) on WSS compared to 6.4 days (SD 1.7 days) on G-ORS. By the second day of treatment, significantly more mothers using WSS (56%) reported that their children had formed stools versus 11% of their G-ORS counterparts; the mean stool frequency after 2 days was also significantly reduced; 3 stools day-1 (SD 2.1) on WSS versus 5 (SD 2.9) on G-ORS. The cereal-based solution was not confused with normal food and led to better feeding patterns. By day 2, 74% of the mothers using WSS had resumed their normal feeding frequencies as opposed to 33% of G-ORS mothers. On recovery the WSS group had gained significantly more weight; the WSS group gained 169 g (SD 142 g) while the G-ORS group lost 150 g (SD 174g). This study suggests by subjective and objective measures that WSS could be considered as an effective home fluid for the first-line treatment of diarrhea.

Abstract
Rice-based oral rehydration solutions have been found to be effective in decreasing stool output and improving intestinal absorption in acute infectious diarrhea. Recent tests of the ability of a rice extract to inhibit intestinal secretions were undertaken, and it was shown that an isolated fraction of rice extract decreased intestinal losses by actively inhibiting the chloride channel.

Abstract
In this study, we have compared the effects of the World Health Organization oral rehydration solution (WHO ORS) and an ORS containing short polymers of glucose (Amylyte ORS) at a high caloric density (five times) and comparable osmolality, on stool output, duration of diarrhea, weight gain and fluid and electrolyte balance, in randomized, open-labeled, controlled clinical trials in five centers. A total of 198 male children (4 months to 10 years) with acute diarrhea ( <72 h after onset) were assigned by random allocation to either WHO ORS or Amylyte ORS at five centers in Asia. Children were stratified according to grade of dehydration (mild, moderate or severe) and the initial purging rates during the first 6 h (low ( < 2 ml/kg/h), moderate (2-5 ml/kg/h) and high ( > 5 ml/kg/h) purgers). The clinical characteristics of the children in the two treatment groups were comparable. Amylyte ORS reduced stool volumes significantly in children with severe dehydration (285.4 +/- 74.2 versus 75.5 +/- 20.0 ml/kg; p < 0.05) and in children with a high initial purging rate (200.3 +/- 42.8 versus 130.5 +/- 9.1 ml/kg; p < 0.05). This was accompanied by a significant (276.4 +/- 14.6 versus 227.6 +/- 11.8 ml/kg; p < 0.01) reduction in ORS requirements in the Amylyte ORS treated group, the effect being greatest in children with severe dehydration (491.5 +/- 108.5 versus 155.7 +/- 27.3 ml/kg; p < 0.01) or high initial purging rates (394.2 +/- 66.2 versus 316.8 +/- 34.8 ml/kg; p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This study documented what retail pharmacists and operators of patent medicine shops prescribe for childhood diarrhoeas in Borno State in the northeastern part of Nigeria. Data was generated by a combination of open and confederates survey of 135 pharmacies and patent medicine shops in the state. The study found that retail pharmacies and patent medicine shop operators, in the overwhelming majority routinely prescribe drugs, particularly, antibiotics, for both watery and bloody diarrhoea. Very few of the pharmacists and almost none of the patent medicine shop operators prescribed any form of oral rehydration therapy (ORT) for watery diarrhoea. There was very high discrepancy between what respondents told interviewers they usually prescribe and what was actually prescribed to confederates in their facilities. It is suggested that the non-prescription of ORT by the majority of facilities could be accounted for by pharmacists' permissive attitude to the norms. This permissive attitude was generated by the profit motive and reinforced by mothers' expectations. The study conclude that more operators can be made to prescribe ORT by instituting incentives for those who prescribe and overt sanctions for those who do not.

Abstract
Rice based oral rehydration therapy (ORT) solutions have been shown to be superior to glucose oral rehydration salts (World Health Organisation (WHO) ORS) in reducing stool volume and duration of diarrhoea in children and adults. Rice based ORT has been used only sparingly in young infants, however, because of theoretical concerns about digestibility. A randomised controlled trial of rice based ORT (50 g rice and electrolytes identical to WHO ORS) and WHO ORS was carried out in 52 male infants less than 6 months old with moderately severe acute diarrhoea to evaluate efficacy and digestibility. Nineteen (70%) of 27 children who received rice based ORT and 18 (72%) of 25 children who received WHO ORS were treated successfully. The mean (SD) diarrhoeal stool output for the first 24 hours of treatment was significantly lower in the infants receiving the rice based ORT than in those receiving WHO ORS (101.0 (60.5) v 137.1 (74.6) g/kg). The stool output was also significantly less in the rice based ORT group in the second 24 hours. Infants in the rice based ORT group drank significantly less rehydration solution than infants in the WHO ORS group (mean (SD) 165.4 (77.4) v 217.9 (86.1) during the first 24 hours of treatment. There was no difference in the duration of diarrhoea between the groups. The volume of breast and formula feeding was similar in the two groups. No difference was seen in the frequency of finding reducing substances or acid pH in the stools of either group of children. The results suggest that rice based ORT is as effective as WHO ORS in infants with moderately severe diarrhoea and that rice based ORT is as well tolerated as WHO ORS in infants.

Abstract
Clinical trials suggest that including naturally occurring complex carbohydrate in oral rehydration solutions (ORS) in place of glucose increases water absorption and reduces stool volume during acute diarrhoea. The mechanisms for this greater clinical efficacy has not been established. This study examined the ability of two hypotonic rice based ORS, RS-ORS (137 mOsm/kg) and RP-ORS (143 mOsm/kg), and HYPO-ORS (240 mOsm/kg) a glucose equivalent ORS, to effect water absorption by in vivo perfusion of normal and secreting rat small intestine. The results were compared with those for two widely used conventional hypertonic ORS, WHO-ORS (331 mOsm/kg) and UK-ORS (310 mOsm/kg). In the normal intestine, water absorption was similar from WHO-ORS (87.4 (45.1-124.6) microliters/min/g; median and interquartile range) and UK-ORS (57.6 (41.5-87)) but less than from the hypotonic solutions (p < 0.02); water absorption from RS-ORS (181.8 (168.5-193.8)) and RP-ORS (195.7 (179.3-207.9)) was similar but less than from HYPO-ORS (241.3 (230.6-279.7); p < 0.005). In the secreting intestine, all ORS reversed net secretion of fluid to net absorption; the hypotonic solutions, HYPO-ORS (105.2 (95.2-111)), RS-ORS (127.7 (118.3-169.4)) and RP-ORS (133.7 (122.1-174.5)), produced more water absorption (p < 0.005) than the hypertonic solutions WHO-ORS (47.1 (29-75.9)) and UK-ORS (24.9 (18.4-29.4)). The rice based ions promoted most water absorption in secreting intestine (p < 0.007). These data indicate that low osmolality is of primary importance in mediating the increased water absorption from cereal based ORS.

Abstract
As a component of a series of studies of childhood diarrhoea in rural Nicaragua, lay knowledge regarding the condition and its appropriate management has been investigated through semistructured interviews with 70 mothers. These data have been combined with information from focus group discussions and observations from investigators who have been resident in the study area for many years. For any episode of childhood diarrhoea, the lay nosology influences the treatment path followed. Thus for some types of diarrhoea, treatment at a health centre or health post and the use of rehydration fluids is seen to be appropriate, while for other types the use of traditional healers or home-based treatment, often explicitly without the use of rehydration fluids, is applicable. The implications of lay nosological systems for the interpretation of epidemiological studies and for the implementation of health promotion programmes are discussed.

Abstract
Diarrhoea remains a leading worldwide cause of morbidity and mortality. In developing countries alone, 1.5 billion episodes of diarrhoea occur per year in children under 5 years of age and approximately 4,000,000 of these result in death. Early, appropriate therapy decreases the risk of complications and death due to diarrhoea. Regardless of the causative agent, oral rehydration and nutritional management are the mainstays of good management of infants, children and adults with diarrhoea. Diarrhoeal disease control programmes throughout the developing world have adopted the WHO case management plan as a standard. In this chapter, we review the history, successes and shortcomings of various oral rehydration therapies and recommend a case management approach that is similar to the WHO plan. Although ORT is safe, effective, convenient and economical, this therapy has not been universally implemented in health care settings. The challenge for clinical and public health practitioners in developing and developed countries is to identify and overcome the barriers that exist so that all patients with diarrhoea will have the opportunity to receive optimal care.

Abstract
In the experience of the author, oral rehydration therapy has proven effective at home, in the ambulatory and in the institutional care setting. A series of anecdotal reports on the successful use of oral rehydration on refugees, in famine and poverty, on medical students, prisoners, and the well-off people of western countries, is presented. The essential principles of oral rehydration are identified and we show how these can be adapted to a particular health care setting. A clear understanding of local attitudes and beliefs about diarrhoea is essential to professional health workers if they are to act as agents of change.

Abstract
Travelers' diarrhea affects almost half of all travelers from developed to developing nations. Its occurrence frequently alters planned activities. Enterotoxigenic Escherichia coli and other bacterial pathogens endemic to the area visited account for the majority of pathogens isolated. Newer research technologies are assisting in defining virulence properties and epidemiologic characteristics. Prudence exercised during travel remains the preferred mode of prevention, reserving antimicrobial prophylaxis for specific situations. Oral rehydration and early pharmacologic intervention with antimicrobial and antimotility agents significantly decrease length of illness when diarrhea occurs.

Abstract
The aim of this study was to determine whether fluid homeostasis could be maintained by using a hypo-osmolar (200 to 221 mosmol/kg), relatively low-sodium (50 to 52 mmol/liter) solution that contained a glucose polymer in a 54-year-old patient with high ileostomy output attributed to short-gut syndrome and resultant prerenal azotemia. Sequential balance studies were performed to assess stool and urinary output, stool fat, and urinary electrolytes initially during intravenous rehydration and subsequently during administration of the necessary fluids and nutrients exclusively by oral supplementation. The additional effects of high-fat and low-fat diet, loperamide hydrochloride, and octreotide acetate were evaluated. When the patient sipped a hypo-osmolar oral rehydration solution while she was awake during the day and received a high dose of loperamide and a 40-g fat, disaccharide-free diet, salt and water homeostasis was maintained. The addition of octreotide did not substantially enhance fluid balance; rather, it increased fecal fat and fluid losses from the small bowel. Thus, hypo-osmolar polymeric glucose solutions maintain fluid homeostasis in patients with the short-gut syndrome. In such patients, simple balance studies are useful for assessing the absorptive capacity of the residual intestine, for developing an optimal individualized treatment, and for eliminating the need for costly, long-term home parenteral nutrition.

Abstract
Five health problems continue to jeopardize the survival of the world's children including prenatal factors, level of nutrition, communicable diseases common to childhood, diarrheal diseases, and acute respiratory infections. Although some of these concerns are being managed effectively in the United States and other Western countries, they still pose tremendous risks for the child born in Asia, Africa, Latin America, or the South Pacific.

Abstract
OBJECTIVE To determine the effectiveness of oral rehydration in children with moderate dehydration caused by gastroenteritis, and to compare the complications of oral and intravenous treatment. DESIGN Randomised controlled trial. SETTING Emergency department and infectious diseases ward in a large urban teaching hospital. PATIENTS 111 children aged 3-36 months who had been previously healthy, had had diarrhoea for seven days or less, had clinical signs of dehydration, and were not in shock. Six children were withdrawn because the diagnosis was incorrect (four in oral group, two in intravenous group) and one (oral group) was withdrawn at her parents' request. INTERVENTIONS Oral rehydration fluid was given by mouth or nasogastric tube, or both to 52 children. The remaining 52 received intravenous rehydration fluids but were allowed to drink. MAIN OUTCOME MEASURES Success or failure of rehydration. Number of times child vomited or passed stool after starting treatment. Time taken to rehydrate. RESULTS Oral treatment failed in two children (failure rate 3.8%, upper 95% confidence limit 11.6%) and intravenous treatment in none. Vomiting was more common in the oral group (p less than 0.01): 26 of 50 children (52%) in the oral group and 11 of 50 (22%) in the intravenous group vomited during rehydration. There was no significant difference between the two treatment groups in the number of stools passed during rehydration (p = 0.09). None of the children had serious complications of treatment. CONCLUSION Rehydration by mouth or nasogastric tube is a safe and effective treatment for moderately dehydrated children with gastroenteritis.
