[Rice water with and without electrolytes in diarrhea with a high stool output].

The objective of the study was to determine the efficacy and safety of two rice-based oral rehydration solutions, with and without added electrolyte in children presenting acute diarrheal dehydration with high stool output (> 10 mL/kg/h) during a two-hour rehydration period. Twenty-two patients of one to 18 months old were recruited and randomly distributed into two groups: group A received the rice-based solution without electrolytes, and group B received the rice-based solution with electrolytes. A stool output diminishing was observed in both groups and rehydration was achieved in 4.0 +/- 0.9 hours in 21 patients from group A and in 4.6 +/- 0.9 hours in 13 patients group group B. There was not a statistically significant difference between the groups regarding the laboratory results. The rice-based oral rehydration solution without added electrolytes was useful for rehydration of children presenting high stool output, after administering the WHO/ORS recommended formula during a two-hour period.

[Cholera in children. A report of 8 cases].

Cholera is an acute intestinal infection caused by Vibrio cholerae 01. When an infected person presents severe dehydration and is not adequately treated, he or she will develop hypovolemic shock and eventually could died. There is scarce information concerning this disease in the Pediatric group. Herein we report on eight cases of Pediatric cholera, in children 17 month to four years of age. Seven patients out of eight were admitted presenting dehydration. Four presenting mild or moderate dehydration and three presenting hypovolemic shock. These three patients were rehydrated by intravenous route and thereafter the hydration was maintained by oral therapy. The outcome was uneventful in six patients. One patient developed abdominal distention probably due to hypopotassemia, and another patient presented hyponatremia and seizures. All the patients recovered within five days after admission.

[Arterial hypertension in children].

It is considered hypertension in children, the persistent increase of the blood pressure values above percentile 95 for age and sex, in no less than three determinations, with adequate register techniques. Blood pressure is maintained mainly by the regulation of metabolism of sodium and water in the intravascular space, through the adequate balance of intake, filtration, reabsorption and renal throughout. It is also regulated by hormonal factors. Weight gain control in teen-agers could be useful to prevent high blood pressure in adults. In children, it is generally secondary to renal, reno-vascular, endocrinological or tumoral diseases. Clinical manifestations and the recommended diagnostic procedures are analysed to detect the most frequent causes of hypertension at different ages. Most cases response with antihypertensive drugs in combination with hyposodic diet. For the hypertensive crisis, asa diuretics and powerful antihypertensive drugs may be employed. Patients with chronic renal insufficiency could also need dialytic treatments. Renovascular diseases require almost always invasive treatments. Better prognosis in children with severe high blood pressure is related with recent diagnostic procedures, surgical techniques and antihypertensive drugs improvements.

[Cholera in pediatrics].

Cholerae is a grave and acute bacterial intestine infection which is caused by a bacilo, V. cholerae 01, that produces toxic products. Its clinical symptoms range from abundant liquid diarrhoea combined with vomiting and rapid dehydration. It is highly lethal when right treatment is not applied. There are also cases of cholera where victims do not show any symptoms of it, that is asymptomatic carriers. Any clinical suspicion of cholerae has to be corroborated by epidemiological data and its diagnostic confirmation should be done by isolating the bacteria, V. cholerae. When beginning the treatment, it is not necessary to confirm the diagnostic and this is based on the restitution of the liquids lost through vomiting and facing using any methods that are recommended for any other type of diarrhoea. The antimicrobial treatment is used only for grave cases. This present revision includes recent knowledge about cholerae emphasising on the effective management of cases through an adequate use of right treatment methods and also using the principal prevention measures against dissemination of this disease.

[The management of diarrheal disease at home in some regions of Mexico].

A survey was carried out between May and October, 1991 in eleven federal entities to know the correct household diarrhea case management (EMECADI). It was observed that among the 15,125 children less than five years old the punctual prevalence was of 6.4% (970 children); the incidence in the previous two weeks was 14.5% (1,605 children) and the annual incidence of diarrhea was 4.5 episodes per child per year. Among the children who presented diarrhea in the 24 hours, the following rates were observed: use of oral hydration solution, 17.1%; use of recommended homemade fluids, 63.2%; oral hydration therapy use, 63.2%; increased fluids, 29.9%; correct oral serum preparation, 60.0%; continued breast-feeding, 75.0%; continued feeding, 59.8%; adequate knowledge about seeking care, 12.5%, and drugs use, 53.2%. The reference and nutritional components should improved.

[Treatment of children with acute diarrheal disease. Knowledge and attitudes of the health personnel].

Diarrheal diseases are still one of the most frequent causes of death due to dehydration in children; lack of information regarding the adequate treatment of diarrhea is the main cause. The results of an inquire sent to 620 physicians and nurses were analyzed to determine the knowledge and attitudes of the health care workers that reside in different diarrheal mortality areas in Mexico. The less professional experience time was correlated with more knowledge in etiology of diarrhea. More physicians than nurses had correct answers regarding the place of diarrheal diseases in child mortality and the correct use of antimicrobial, and other drugs and liquids to prevent and treat dehydration. Most workers did not know the inconvenience of hypertonic solutions to prevent dehydration and the importance of the oral solution flavor. This results suggest that nurses will, be included in clinical training by means of seminars in oral hydration therapy. Furthermore it seems convenient to increase the access to oral hydration solutions as well as the diffusion of its advantages.

Rice solution and World Health Organization solution by gastric infusion for high stool output diarrhea.

We sought to determine the efficacy of three different types of treatment in children with acute diarrhea who, during the oral rehydration period, had high stool output (greater than 10 mL/kg per hour). Sixty-six children, aged 1 to 18 months, with an average stool output of 22.6 mL/kg per hour were randomly distributed into three groups: group 1 received a rice flour solution, group 2 received the World Health Organization rehydration solution by gastric infusion, and group 3 continued to receive this solution orally. In all three groups, a decrease in stool output was observed, with the higher decrease observed in group 1 patients. Such a decrease facilitated rehydration of all 22 patients in group 1 (100%) in 3.3 +/- 1.5 hours, 16 (73%) in group 2 in 4.3 +/- 2.1 hours, and 15 (69%) in group 3 in 4.9 +/- 2.0 hours. No complications were observed. These data indicate that the rice flour solution is effective in children with high stool output diarrhea.

[Efficacy of a rice-based beverage for the management of dehydration caused by acute diarrhea in children].

We tested the clinical efficacy of a rice-powder gruel (RPG) as an oral rehydration solution in a randomized clinical trial, comparing it with oral rehydration salts (ORS) prepared as recommended by WHO. RPG was prepared as mothers do it in a rural area, according to previous ethnographic work. RPG has sugar but no sodium or other electrolytes. Seventy patients under 5 years old with mild to moderate dehydration due to acute diarrhea were included in the trial. Ninety-two percent of children were successfully rehydrated with RPG and 91% of children were successfully rehydrated with ORS. Patients in the study group required less time to rehydrate and presented a reduction in fecal output as compared with the control group. We propose that the rice-powder gruel should find its place as a first line of treatment at the home level, when oral rehydration salts are not available, to prevent dehydration in the child affected with acute diarrhea, and that its use should be closely linked to no suspension or rapid reintroduction of oral feeding to provide an external source of sodium and other nutrients.

[Oral rehydration at a third-level service].

Oral rehydration therapy (ORT) has been shown to be useful in decreasing mortality, reducing treatment costs and diminishing the frequency of complications in children under the age of five with acute diarrhea. The current concept of ORT includes not only the increase in the intake of fluids and the administering of oral solution in order to prevent or treat dehydration, but also the continuance of everyday feeding, the teaching of the child's mother to detect signs of dehydration and other alarming changes, as well as the non-administering of medication, especially those considered as anti-diarrheal or anti-vomiting, and limiting the use of antimicrobials, only to be used in special cases. The theoretical know-how of these concepts has been seen to be insufficient in order to increase the use of community-wide Oral Rehydration Therapy, being this the main purpose for the establishment of the Oral Rehydration Ward in teaching hospitals of second and third level, where the majority of its' personnel must come into contact with and share the responsibility of treating children with diarrhea. Within these wards students obtain information, ability and assurance in the effective actual management of children with diarrhea, including the correction of the state of dehydration through the administering of oral solutions. Another complementary benefit from the coming about of this ward is the decrease in the need to hospitalize the majority of the patient with diarrhea therefore reducing costs and any related complications.

[Sodium concentrations in solutions for oral rehydration in children with diarrhea].

Using the appropriate treatment for dehydration due to diarrhea, over a million deaths a year in children under five are being prevented. After analyzing the information related to the concentration of sodium in solutions used for oral rehydration, the following conclusions can be made: 1. Solutions with high glucose content, as well as hyperosmolar foods, favor the development of hypernatremia. Not so, sodium concentrations of up to 90 mmol/L, with glucose under 2.5%. 2. There are other factors which correlate with the presence of hypernatremia: abundant watery diarrhea, a good state of nutrition, under six months of age and the administration of solute loads, orally (boiled milk) as well as intravenously. 3. The WHO oral rehydration solution which contains, in mmol/L: sodium 90, glucose 111 (2%), chloride 80, potassium 20 and citrate 10, with a total osmolarity of 311 or 331 mOsm/L, is the one which more closely resembles the ideal concentration and has shown to be effective, not only in the treatment of dehydration due to diarrhea, but has also been to be useful in the prevention and maintenance of rehydration, independently from the etiology, the patient's age or the state of nutrition. 4. The use of oral serum with a sodium concentration of 90 mmol/L, reduces the natremia more slowly, therefore protecting the patient with hypernatremic dehydration from developing convulsions during treatment. This sodium concentration is also the best for cases of hyponatremic dehydration. 5. Using the recommended norms in cases of children with diarrhea, including continuing regular feeding habits and the adding of complementary liquids, no cases of hypernatremia have been recorded.(ABSTRACT TRUNCATED AT 250 WORDS)

[Oral rehydration in newborns with dehydration caused by diarrhea].

The clinical experience obtained while treating 43 dehydrated newborns due to diarrhea with oral rehydration solution (ORS) using the formula recommended by the World Health Organization is reported. Of the 43 patients, 26 were severely dehydrated (greater than equal to 10% of weight recovery once rehydrated). The averaged time need to correct the dehydration was 4.7 +/- 2.7 hours, with a average intake of ORS of 26.5 +/- 7.5 mL/kg/hour. Children who were being breastfed continued so during the rehydration period. Two of the patients were hospitalized for intravenous treatment, one was due to persistent vomiting during rehydration and probably due to sepsis, and the other due to necrosing enterocolitis. The oral rehydration therapy was successful in 95% of the newborns included in the study, which proved the method to be safe and adequate for the correction of dehydration due to diarrhea among these patients. Similar experiences are reported in Mexico as well as from other countries, which also suggest the use of this therapeutic procedure in children of this age.

[Treatment of diarrheic disease at home. Comparison of 2 forms of oral solutions: liquid and concentrated in small bags].

One hundred children, ranging in ages from a month to a year, with acute diarrhea who were treated at home following the basic standard recommendations, were studied. In order to prevent dehydration, half of the children were given oral solution (OS) containing the concentrated official formula in packets (group A), and the remaining half was given a commercially prepared ready-to-use OS (group B). During the treatment period, two house calls were made and the third day the patient was asked to come in for a check-up at the hospital. The clinical and socioeconomic characteristics were similar in both groups. The majority of parents made some reference to the "salty" taste of their OS, while only a few thought it has a sweet taste. In Group B, there were greater numbers of relatives who did not wash their hands before administering the OS and did it through bottles. A reminder was given on suggestive signs of dehydration expected, during the second home visit, although they were few. In both groups the average amount of OS administered was greater than 40 mL/kg/24 hours. The majority of the patients gained weight during the treatment. Four patients showed signs of slight dehydration (three from group A and one from group B). The OS's bacteriologic examination was positive for enteropathogens in 16% of the samples from group A and in 5% from group B. The average time the diarrhea continued was similar for both groups. Sodium concentration ranged from 60 to 120, potassium from 15 to 30 mmol/L, in 85% of those cases in group A and 98% in group B.(ABSTRACT TRUNCATED AT 250 WORDS)

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

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