The activity of lysozyme in feces was estimated in a control group of 50 healthy infants and in a group of 152 infants with acute diarrhoea. All infants investigated were artificially nourished. In the latter group the activity of lysozyme was estimated twice: a) at the beginning of clinically active phase of the disease and (b) in the convalescence period immediately after withdrawal of clinical symptoms. The range of normal values was 14.9--77.0 (average 44.0) of egg-white lysozyme units/g dry feces. In acute diarrhoea the activity of lysozyme in feces was found to be elevated in 72.4% of cases in the first determinations and in an additional 7.6% of cases in the second determination (i.e. a total of 80% of cases in both determinations). The average elevations of lysozyme activity in the feces and the dynamics of their normalization after withdrawal of clinical symptoms were generally related to the severity of the disease.

Swedish children and adults (648 patients) with acute diarrhoea were investigated for enterotoxigenic strains in stool cultures. A total number 74 strains were isolated from 28 patients and assayed in the rabbit intestinal loop test and the adrenal cell test. Only three of the enterotoxigenic E. coli (ETEC) isolates belonged to classical enteropathogenic serotypes of E. coli (EPEC). Two enterotoxigenic strains of Proteus morganii, two of Enterobacter hafniae and one of Citrobacter freundii were isolated. None of 67 EPEC strains were found to produce a heat-labile enterotoxin (LT) in either of the two test systems. A number of Yersinia enterocolitica and Pseudomonas aeruginosa strains from stool cultures often produced toxic effects in the cell test but no enterotoxin activity was detected for any of the strains investigated either in the adrenal cell test for heat-labile enterotoxin (LT) or the suckling mouse test for heat-stable enterotoxin (ST). All EPEC isolates were also tested for ST and for invasive properties in the Sereny test; each isolate was negative in both test systems. It is concluded that production of LT and ST enterotoxin were common in stool isolates from Ethiopian children but a rare phenomenon among Swedish children with acute infantile diarrhoea. Isolation of aerobic stool bacteria with invasive properties seems to be uncommon both in Ethiopian and Swedish children. However, since both LT and ST as well as invasive properties seem to be very unstable genetic properties in many of these stool isolates improved sensitive methods for the last two properties will probably change this picture in the future.

Acute diarrhoea is a frequent, worldwide complaint. On any given day, 200 million people suffering from gastroenteritis will pass a volume of diarrhoeal water comparable with the flow of water over the Victoria Falls in one minute. In most attacks, routine microbiological techniques will fail to demonstrate the cause.

22 infants under age two years were admitted to the Ubol Provincial Hospital in Northeast Thailand with acute diarrhea. The house physician saw them and judged them to have moderate dehydration. 11 infants aged from 4-10 months were given nasogastric infusion; another 11 infants aged from 5-17 months received intravenous fluid. The absorption of nasogastric infusion fluid was remarkable as could be seen by the amount of stool loss, weight gain, reduction of serum specific gravity and urea nitrogen. Biochemical study showed high incidence of hypernatremia which could be explained by the limited fluid intake in these infants during diarrhea. Nasogastric infusion fluid which contained only table salt and cane sugar could provide effective volume. Electrolyte imbalance and metabolic acidosis were gradually corrected at a similar rate to bicarbonate containing solution as reported by others. Balance study indicated taht nasogastric infusion retained less nitrogen and sodium during the course of treatment as compared to intravenous infusion. All the infants recovered from diarrheal disease once dehydration was corrected without complications.

Etiology and Pathophysiology. The present article is a comprehensive review of recent research results in the field of acute diarrhea. The most important new idea in contrast to older views is that almost all acute diarrheas are associated with a disturbance of intestinal bacterial homeostasis: overgrowth of the small intestine with apathogenic or pathogenic organisms is followed by changes in intestinal metabolism with increase in intestinal water and electrolyte secretion. Anaerobic organisms cause by enzymatic deconugation and dydroxylation of bile acids secretion of fluid into the small intestine and inhibition of fluid absorption from the large intestine. 10-OH-fatty acids, which are formed intraluminally by enzymatic hydroxylation of long-chain unsaturated fatty acids from the diet by similar anaerobic organisms, produce profuse secretion of fluid into the small intestine. The ability of numerous strains of E. coli to produce enterotoxin, which has a qualitatively similar action to cholera toxin, is now considered to be a major cause of infantile diarrhea. The separation of two completely different pathophysiologic mechanisms of E. Coli, the enterotoxic and the enteroinvasive action which are determined by extranuclear chromosomal material, is an important result of recent research. Overgrowth of the small intestine with different bacteria is followed by loss of actiivity of lactase, and later of all disaccharidases in the intestinal mucosa.

Changes in composition of Escherichia coli were followed during antibiotic therapy of nin children with acute diarrhea. In five cases enteropathogenic serotypes of E. coli were multiple-drug resistant, and in four other this feature characterized nonpathogenic E. coli strains. The results point to the importance of choice of the drugs effective not only against pathogenic serotypes, but also against nonpathogenic ones, and uselessness and even harmfulness of chemotherapy "in blindly".

Twenty-five children with cows' milk protein intolerance were studied. Twenty had presented with an illness clinically indistinguishable from infantile gastroenteritis; an enteropathogenic Escherichia coli was isolated from the stools in two children, and in six another member of the family simultaneously developed acute diarrhoea and vomiting. Twenty-three children had lactose intolerance secondary to cows' milk protein intolerance. Eight out of 20 children were found to be partially IgA deficient. An acute attack of gastroenteritis, in damaging the small mucosa, may act as a triggering mechanism in cows' milk protein intolerance, and a deficiency in IgA may be a predisposing factor in so far as it allows the patient to become sensitised to foreign protein.

Bacteriological studies of jejunal mucosal biopsy specimens and contents were performed on 22 hospitalized adult patients with acute diarrhoea and 24 control normal subjects. None of the washed homogenates of the mucosal specimens were sterile and only one fluid specimen obtained from a control subject was sterile. A definite enteric pathogen was found in only five of the 22 diarrhoea patients. There was no qualitative difference in the bacterial profile of the jejunal mucosa and contents of the diarrhoea patients from that of the control subjects, but there were significant quantitative differences for some bacterial categories. In the control as well as diarrhoea subjects, there was no qualitative difference in the bacterial profile of the jejunal mucosa from that of the fluid, but there were significant quantitative differences for some bacterial categories. The significance of the findings is discussed.

Planning the strategy in diagnosis of diarrhea some questions need to be answered: 1. Do the complaints in question fulfill the defined criteria of diarrhea? 2. Is it an acute diarrhea of infectious origin requiring fast microbiologic diagnosis? 3. Is it a chronic diarrhea? A) Do anamnestic findings and present status induce a certain suspected diagnosis, as in hyperthyreoidism, drugs, intestinal resections? B) Is a complete stepwise diagnostic planning needed as in Crohn's disease, insufficiency of the pancreas, non tropical sprue? Diagnostic measures have to be taken into consideration according to the answers given.

The AA are proposing a dietotherapy in the diseases of the gastrointestinal tract in infancy, characterized from acute diarrhoea. A slow hydrolysis product of casein is used for this purpose. The AA after description of the very good results obtained, are calling the attention on the fact that the advantage was realized only with a food product and not with drugs.
