A total of 120 (80 males and 39 females) newborn Holstein-Frisian calves suffering from acute diarrhoea were studied clinically and biochemically, including the following parameters: pH, pCO2, act. HCO3, BE, RBC, PCV, HV, glucose lactate, urea, creatinine, total bilirubin, total protein, AST, Na, K and Cl. The results were interpreted according to their healthy condition, their age as well as their sex. The study had revealed an extreme metabolic acidosis, haemoconcentration, hypoglycaemia and hypofunction in the kidney and liver. Furthermore, the calves with diarrhoea had showed hyponatraemia, hypochloraemia, and hyperkalaemia. Important correlations between clinical and some blood parameters were found. Metabolic acidosis was more severe in male calves than females. These pathophysiological changes should be put in consideration during the therapy of newborn calves suffering from diarrhoea.

We studied 108 children between 3 and 36 months of age with acute diarrhea and dehydration when their diarrhea continued more than 24 hours following initiation of ORT and in whom we measured pH and glucose of stools with strips in all evacuations. According to the average stool pH and glucose in the first six hours, the patients were grouped in pH < or = 5.5 and > 5.5 and a glucose < or = 1+ and > 1+. The pH of stools < or = 5.5 increased significantly (P < or = .0005) in children between > 6-12 hours and by 48 hours, it was similar to those with an initial average pH 6.6 Stool glucose declined considerably between > 12 and 24 hours. Contrary to what we expected to find, children with pH > 5.5 excreted more stools and had a higher ORT intake in the first 24 hours. The systematic studies of pH and glucose of stools did not appear to be useful for children with acute diarrhea who had a satisfactory evolution.

We compared the efficacy of a maltodextrin containing oral rehydration salts (ORS) solution with that of the WHO recommended glucose-ORS solution in a double blind randomized study of treating 69 children (33 in experimental group; 36 in control group) aged 4-36 months with acute diarrhoea causing mild to moderate dehydration. Both the groups of children were similar in initial clinical characteristics and received only ORS solutions. No significant differences in stool output (median 88.0, range 34-320 g/kg body wt. in experiment vs 75.0, 25-410 g/kg in control), intake of ORS solution (125.0, 58-360 ml/kg body wt. vs 154, 130-250 ml/kg), and duration of recovery from diarrhoea (2.0 d, range 1-6 vs 2.0 d, 1-9) were found between the groups. The haematocrit and serum electrolyte values in the two groups 24 hours after starting treatment were also similar. The results suggest that the ORS containing maltodextrin (50 g/l) in place of glucose has no advantage over WHO-ORS in correcting mild to moderate dehydration of children with acute diarrhoea.

Dehydration, in childhood as in adulthood, may origin from an inadequate water ingestion or an excessive water elimination. Causes may be found in fever, vomiting, scalds, pulmonary hyperventilation, diabetes. Water loss during acute diarrhea in children can be even 6-7 times higher in comparison with an healthy child. Together with water, electrolytes are lost. We differentiate dehydration in isonatremic d. (70% of cases), hyponatremic d. (10%) and hypernatremic d. (20%) basing on Sodium loss. Important dehydration causes severe clinical symptoms as shock, renal and cardiocirculatory failure, convulsion, coma. Symptoms at the central nervous system level derivate both from hyperosmolarity in brain cells and from thrombosis or hemorrhages in subdural sites. Dehydration, following acute diarrhea, is slight when weight loss is lower than 5%. The child health conditions still remain good. Dehydration become moderate if weight loss reaches 5% and the child starts suffering. When the weight loss reaches 10%, dehydration is now severe and circulatory deficiency becomes evident. When it is higher than 10%, prognosis is very severe and shock and coma may be observed. In the present work, we illustrate the different ways of rehydration after acute diarrhea. Initially, oral rehydration must be established with one of the oral solutions, differing each other for amount of electrolytes and glucose. Recently, a new solution, "supersolution", has been presented differing from the other ones for electrolytes concentration and for the presence of rice starch instead of glucose. In most cases of diarrhea, oral rehydration appears adequate but sometimes an intravenous rehydration becomes necessary, e.g. in case of vomiting, CNS depression and in any case of severe gastroenteric symptomatology.(ABSTRACT TRUNCATED AT 250 WORDS)

As acute diarrhoea gives rise to a loss of water and electrolytes, the most effective therapy results the oral rehydration. Harrison and Darrow tried this way first. Only in the years '60 we began to use oral rehydration commonly. Usually, solutions contain glucose, Na, K, Cl, Bicarbonate in various concentration. When glucose is replaced by rice starch or when amino acid are added, then we have a "supersolution". Nutrients intake provides more calories and increases absorption Na-depending. We used one of these new "supersolutions". Two groups of children, hospitalised for acute diarrhoea, were treated with different rehydration solutions. The first one (Dicodral Forte), prepared according to the WHO, contains glucose and electrolytes as we know. The second one (Amidral) has rice starch instead of glucose and presents a lower concentration of Na and Cl. The present study looked over: A) Weight increase from the first to the third day of hospitalisation in our department. B) Duration of diarrhea. C) Number of stools. D) Haematological values before and after rehydration. All the patients ingested the same amount of solution. Children which received WHO's solution presented diarrhea longer than others (2.55 +/- 2.06 vs 2.2 +/- 1.1 days). Number of stools was below average too (3.05 +/- 2.64 vs 2.8 +/- 1.5). Refeeding was done employing the same milk used in former times. AMIDRAL was used to dilute the milk when it was possible. Most important result is the increase of weight we had using this "supersolution". 15/20 children which received AMIDRAL showed an increase of their weight as shown in Tab. 1.

The safety and efficacy of standard oral glucose-electrolyte solution, containing 90 mmol of sodium per litre, was evaluated in the treatment of dehydrating diarrhoea among severely malnourished (marasmic) children. A total of 81 male children aged between 6 and 48 months were studied; 41 were in the malnourished group (study group: less than 60% of Harvard Standard weight-for-age) and 40 were in the well-nourished group (control group: 80% or more Harvard Standard weight-for-age). Children of both groups could be rehydrated with standard oral rehydration solution (ORS) without encountering any clinical or biochemical complications. The results of this study lend support to the World Health Organization's concept of a unified formula of ORS for the treatment of all cases of acute diarrhoea, including severely malnourished children.

To determine how closely US pediatricians follow the 1985 American Academy of Pediatrics Committee on Nutrition's recommendations on oral therapy for acute diarrhea, a questionnaire was administered to four groups: New England private practitioners, pediatricians from 27 states attending a postgraduate course, representatives of departments of pediatrics at US schools of medicine, and housestaff at Boston Children's and Massachusetts General hospitals. The responses from departments of pediatrics and housestaff were not significantly different from those of community practitioners in most categories. The reported rate of use of glucose-electrolyte solutions recommended by the American Academy of Pediatrics was not different from the use of nonphysiologic, high-osmolar, low-salt solutions such as sodas and juices. The usage rate for glucose-electrolyte solutions meeting the American Academy of Pediatrics-recommended carbohydrate-to-sodium ratio of less than 2:1 was less than 30%. Other findings included the general lack of agreement on the use of a single type of therapy and the common use of oral therapy only for mild or no dehydration. Although the American Academy of Pediatrics recommends that feeding be reintroduced in the first 24 hours of a diarrheal episode, the majority of respondents withhold feeding until the second day or later. These findings indicate that educational programs on oral therapy during acute diarrhea are needed in the United States.

Several issues involving glucose-based oral rehydration therapy may limit its acceptability and sustained use. Our studies suggest that defined short-chain glucose polymers (2 to 9 glucose units) are hydrolyzed and absorbed faster than isocaloric solutions of D-glucose in the small intestine of the rat. Glucose polymers, primarily from rice-based solutions, have been shown to be as effective as glucose-based solutions. They offer additional advantages in reducing the amount and duration of diarrhea with lesser volumes of solution, thereby reducing the costs of treatment. Rice-based solutions provide high caloric density and increase the absorption of sodium without an osmotic overload. The result is increased net absorption of glucose, sodium, and water. Glucose polymers from rice or other starches in oral rehydration solutions may be effective, inexpensive, easily used, and safe treatments for acute diarrhea.

Whole gut perfusion in humans was used to compare the effect on intestinal water and electrolyte transport of the World Health Organisation oral rehydration solution (solution II, composition in mmol/l: glucose 111, sodium 90, bicarbonate 30, potassium 20; 308 mOsm/kg); a hypertonic commercial oral rehydration solution (solution III, glucose 188, sodium 50, bicarbonate 20, potassium 20 mmol/l; 335 mOsm/kg); and three experimental bicarbonate free, hypotonic oral rehydration solutions: solution IV (glucose 111, sodium 60, potassium 20 mmol/l; 260 mOsm/kg), solution V (glucose 80, sodium 60, potassium 20 mmol/l; 219 mOsm/kg), and solution VI (glucose 80, sodium 30, potassium 20 mmol/l; 177 mOsm/kg). Perfusion of the intestine with a standard cleansing solution (solution I, sodium 125, potassium 10, bicarbonate 20, sulphate 40, mannitol 80 mmol/l; 275 mOsm/kg) confirmed published data on minimal water and sodium absorption. Experimental solution VI produced maximum water absorption (mean (SE) +1660.0 (29.8) ml/h) significantly greater than solution II (+1195.3 (79.5) ml/h), III (+534.7 (140.3) ml/h), IV (+1498.0 (42.7) ml/h), and V (+1327.7 (24.4) ml/h; p less than 0.05). Sodium absorption was significantly greater with solution II (+97.4 (7.9) mmol/h) compared to VI (+43.3 (7.8) mmol/h; p less than 0.01) but not compared to IV (+67.2 (13.0) mmol/h). A hypotonic oral rehydration solution such as solution VI may provide optimal replacement treatment for patients with acute diarrhoea.

Before 1970, laboratory staff could not only identify the causative organism of acute diarrhea in 20% of cases, but in 1990, they could identify it in 80% of cases. These organisms are either bacteria, virus, or parasites. The bacteria include enterotoxigenic bacteria (Vibrio cholerae, enterotoxigenic Escherichia coli, Clostridium perfringens, and Staphylococcus aureus) and enteroinvasive bacteria (Campylobacter jejuni, C. coli, and Salmonella and Shigella species). The leading cause of death in diarrhea patients is dehydration. Oral rehydration solutions (ORS) can alleviate mild and moderate dehydration regardless of the etiology of the diarrhea or the age of the patient. WHO recommends an ORS containing glucose and various electrolytes which permit salt and water absorption in many cases of acute diarrhea. Due to the possibility of excess salt entering the bloodstream (hypernatremia), some pediatricians do not use the WHO recommended ORS in newborns and young infants. Instead they use 2 parts ORS followed by 1 part water. This treatment is not easy for illiterate mothers to follow, however. Continued breast feeding during diarrheal episodes along with administration of ORS protects not only against dehydration, but also hypernatremia. ORS should not be administered in severe case of dehydration, however. Medical personnel need to administer replacement fluid such as Ringer's Lactate solution intravenously regardless of the age group. Once the initial deficit has been controlled, ORS administration and reintroduction of foods can follow. Antibiotics should only be administered if the medical personnel suspect severe cholera in an endemic area (tetracycline and furazolidone); shigellosis, but 1st the bacteria must be tested to see if the strain is multiple drug resistant (ampicillin, trimethoprim-sulphamethoxazole, furazolidone, nalidixic acid), and acute amebiasis or giardiasis (metronidazole and tinidazole). Antidiarrheals should not be used.
