The frequency of adverse reactions (dermatitis, myositis, and gastroenteritis) to cromolyn sodium in asthmatic patients was 2% (B/375). Reactions were non-life-threatening and completely reversible. Immunologic evaluations, including skin and serum tests for immediate and delayed reactivity, all were negative. Adverse reactions to cromolyn do not appear to be based on an immunologic mechanism. Cromolyn appears to be a safe drug for the treatment of asthma.

Strains of the swine transmissive gastroenteritis (TGE) virus were isolated for the first time in Bulgaria in 1972. The dynamics was followed up of some strains' propagation in primary cell cultures of kidney tissue and subcultures of the thyroid of pigs. The intracellular virus reached highest titers at the 24--48th hour in the kidney cells, and at the 24--36th hour in the thyroid cells, while the extracellular virus was subjected to inactivation by the 2nd hour after infecting the cultures, by the 4--6th h its titer dropped up to 50 per cent of its initial value, and by the 24th h it was completely inactivated. The viability of the virus was tested after freeze-drying and after it had been stored at 4degreesC and--20degreesC. It was found that chloroform fully inactivates the virus at 4degreesC for 24 hours. The same results were obtained with the use of sodium desoxycholate. The strains isolated in this country form plaques, and with some strains the plaques are of a varying size. Halogenic desoxyuridines (IUDR, BUDR), as well as 8-azoridine do not suppress the multiplication of the tested TGE strains even in high concentrations. Inhibitory effect has 5-bromurazyl which in given concentrations affects the titer of the virus and the size of the plaques formed. Two Bulgarian and two reference strains have lowered their plaque-forming titer by 2 log after being treated with rifamycin-B or rifampicin.

During the period of May 1972 to March 1977, twenty-one fatal cases of rotavirus acute gastroenteritis were recorded in the city of Toronto. The mean age of these subjects was approximately 1 year. Boys outnumbered girls by 12 to 9. Death occurred within three days of onset of symptoms in all cases. Sixteen of the subjects were profoundly dehydrated and had sodium levels (serum or vitreous humor) in excess of 150 mEq/liter. In 11 subjects, sodium values were greater than 160 mEq/liter. Although a physician was contacted in 16 instances, these infants still perished. We suggest that both language difficulties and the rapid rate of fluid depletion contributed significantly to the fatal outcome. At autopsy the bowel was often dilated and filled with fluid. Postmortem autolysis precluded an accurate histological assessment of the small bowel mucosa.

Children repeatedly admitted to a Jamaican clinic with gastroenteritis associated with protein-energy-malnutrition (PEM) were treated by oral glucose-electrolyte rehydration. Children were fed other food from the outset if they so requested. The solution was administer by cup and spoon, i.e., small amounts vs. bottle administration, frequently throughout the day and night. A simple solution, very inexpensive, is outlined and includes a 3-finger pinch of salt, a 3-finger pinch of sodium bicarbonate, and 2 teaspoons of potassium chloride dissolved in 100 cu. cm of water. In all, 16 children suffering from sporadic, unspecific diarrhea over a period of 9 months showed marked improvement of the condition within 1-2 days of cup and spoon rehydration.

The recent epidemic of cholera on the Pacific Ocean atoll of Tarawa, Gilbert Islands renewed interest in the use of coconut water as a rehydration fluid. Fifty-one samples of coconut water from Tarawa were analysed for a variety of constituents to assess its potential usefulness in the oral and parenteral rehydration of patients with cholera and other severe forms of gastroenteritis. Compared to oral rehydration fluids known to be effective in cholera, coconut water was found to have adequate potassium and glucose content, however was relatively deficient in sodium, chloride and bicarbonate. The addition of table salt to the coconut water is suggested to compensate for the sodium and chloride deficiency. In areas of the world where coconuts are plentiful, the advantages of sterility, availability and acceptability make coconut water theoretically feasible for the oral rehydration of patients with severe gastroenteritis when conventional fluids are unavailable.

Analysis of nearly 90 commercial "clear" fluids, including soups, juices, fruit-flavoured drinks and ices, carbonated beverages and gelatins, showed a range of 0.1 to 251 mmol of sodium and 0.0 to 65 mmol of potassium per litre; the osmolality ranged from 246 to more than 2000 mOsm/kg of water. Knowledge of these values is useful in the home or hospital management of patients for whom control of fluid and electrolyte intake is indicated. The results of the analyses are presented in tabular form for use by physicians and nutritionists when counselling patients to ingest clear-type fluids for various illnesses. Examples are given using these data to show how clear-fluid therapy can be tailored in one such illness--gastroenteritis (infectious diarrhea).

The feeding habits of 70 infants under 6 months old hospitalized with acute gastroenteritis were studied to determine whether current efforts to discourage high-solute feeding were having an effect on the incidence of hypernatremic dehydration. Fifteen infants (21%) were fed modified (low-solute) milks and 55 (79%) unmodified (high-solute) milks. Of 47 infants under 3 months old, 15 (32%) had commenced mixed feeding. Plasma sodium level was estimated in 60 infants. Mean values in the modified and unmodified groups were the same, at 137 mEq/liter. Only one infant was hypernatremic (sodium level, 152 m/eq/liter). Osmolalities of 65 samples of milk were measured to provide a measure of milk concentration. Only ten (16%) exceeded by more than 25% that recommended by the manufacturers. Twenty-two (34%) were less than 75% of the recommended concentrations. These improved feeding practices have probably contributed largely to the very low incidence of hypernatremia by preventing dangerously high solute intakes at a time of particular vulnerability.

One hundred and thirty admissions to Alice Springs Hospital of full-blood Aboriginal children with acute gastroenteritis during a six-months period in 1975-1976 were examined retrospectively. Sixty-two (48%) of the children were malnourished, including seven (5.4%) who were marasmic. An accelerated weight gain was demonstrated during the recovery phase, averaging 418% of that expected for age. Hypokalaemia occurred in 77 of 117 children (66%); it was severe (serum potassium levels being less than or equal to 2.5 mmol/l.) in 15 (13%), and did not correlate with dehydration as assessed by initial weight gain, or with nutritional status. Hyponatraemia occurred in 32 of 123 children (26%) and was severe (serum sodium levels being less than or equal to 130 mmol/l.) in 11 (9%). Hypoalbuminaemia (serum albumin levels below 35 g/l.) and anaemia (haemoglobin values below 10 g/100 ml) occurred in 15% and 22% respectively. Potential faecal pathogens were isolated during 80 of the 130 admissions (62%). Multiple pathogens were common. Interrelationships of nutrition, infection and immune response are discussed, and measures for reducing morbidity and mortality are outlined.

To understand mechanisms of viral diarrhea further, we studied ileal ion transport in vitro in relation to mucosal changes and epithelial differentiation in transmissible gastroenteritis in piglets, an invasive viral enteritis thought to involve mainly proximal intestine. In infected pigs, at the height of diarrhea, short-circuited ileal epithelium failed actively to transport Na+ and Cl-, and there was a defect of glucose-mediated Na+ transport. The Cl- secretory response to theophylline remained intact. Conductance measurements indicate that paracellular permeability may be reduced and transcellular transport may be altered. A mucosal lesion was observed at the time of the transport changes, characterized by villus blunting, crypt hyperplasia, and immature crypt-type enterocytes on the villus epithelium, deficient in disaccharidase and (Na+, K+)ATPase activity but rich in thymidine kinase. Consideration of the major determinants of diarrhea in this invasive enteritis must take into account not only altered mucosal function and differentiation but also the extent of intestinal involvement, including the ileum, a major site of fluid absorption in the intestine.

The histopathological changes that occur in the jejunal mucosa of humans infected with the Norwalk or Hawaii agent of acute infectious nonbacterial gastroenteritis ("viral" gastroenteritis) have ben well characterized. The pathogenesis of diarrhea in this syndrome remains unknown; however, recent reports have suggested a possible role for the adenylate cyclase system. In this combined paper, two groups of investigators working independently and employing slightly different techniques report that: (1) there is marked interindividual variation in the apparent specific activity of adenylate cyclase in human jejunal biopsy tissue; (2) such variation can be minimized by expressing enzyme activity as a fraction of maximal that can be stimulated by 10(-2) M sodium fluoride; and (3) adenylate cyclase activity in jejunal mucosa is not increased during diarrhea or illness in human viral gastroenteritis, therefore suggesting no role for the adenylate cyclase system in the pathogenesis of diarrhea in this common clinical entity.
