A major outbreak of gastroenteritis was traced to Cheddar cheese contaminated with Salmonella typhimurium. There were no significant differences in pH values of the contaminated (mean pH 5.31) and non-contaminated (mean pH 5.39) cheese. The isolation rates of Salm. typhimurium were about the same when cheese samples were homogenized in lactose broth, lactose broth containing 1% Tween 80, or in aqueous 2% sodium citrate. Salmonella typhimurium was isolated regardless of preenrichment in lactose broth, but required selective enrichment in selenite cystine or tetrathionate brilliant green broth. There were no marked differences in the isolation rates obtained with different selective enrichment media, or after incubation at 36 degrees and 43 degrees C for 24 or 48 h. Contaminated samples of cheese failed to yield Salm. typhimurium consistently despite large and multiple samplings; samples from the interior of cheese blocks yielded positive results more frequently than the samples from the exterior. The number of Salm. typhimurium in factory sealed blocks as well as in samples obtained from the homes of known cases of salmonellosis was found to range from less than 3/100 g to 9/100 g of cheese. The infective dose of Salm. typhimurium in contaminated cheese was probably no greater than 10(4) organisms, and a rapid decline in numbers of Salm. typhimurium must have occurred subsequent to the outbreak.

A clinical study on imipenem/cilastatin sodium (MK-0787/MK-0791) was carried out and the following results were obtained. MK-0787/MK-0791 was used for treatment of a total of 33 patients and clinical effectiveness, bacteriological efficacy and adverse reactions were evaluated. The clinical effects were excellent in 1 case, good in 21 cases and fair in 2 cases in a total of 24 cases with respiratory tract infections, were excellent in 5 cases and good in 1 case in a total of 6 cases with urinary tract infections, and were good in 2 cases and fair in 1 case in a total of 3 cases with gastroenteritis. Causative organisms isolated from 11 patients were 1 strain of Gram-positive cocci and 10 strains of Gram-negative bacilli. Ten out of 11 strains were eradicated for an eradication rate of 91%. The clinical efficacy was confirmed in 11 cases for an efficacy rate of 100%. The bacteriological study has shown that MK-0787/MK-0791 has a strong antimicrobial activity. No side effects were observed. There was only one abnormal laboratory finding, i.e., a case of eosinophilia.

Alterations in serum ionized and total calcium, magnesium, and phosphate concentrations, during recovery from acute dehydrating gastroenteritis, were studied. Fifteen children with acute dehydrating gastroenteritis had serum concentrations of ionized and total calcium, magnesium, phosphate, sodium, potassium, chloride, urea, creatinine, and albumin, as well as acid-base status, evaluated during rehydration and up to 72-h postadmission. The total serum calcium corrected for albumin did not change significantly during rehydration and remained within the normal range. Although serum ionized calcium fell significantly at 24 and 72 h, its concentration was not sufficiently decreased to cause symptomatic hypocalcemia. Serum ionized calcium correlated significantly with pH (r = -0.57), bicarbonate (r = -0.63), and albumin (r = +0.65), but not with total serum calcium, magnesium, and phosphate. Serum magnesium remained within the normal range during the study period. Serum phosphate was increased on admission (2.64 +/- 0.77 mmol/L), decreased by 12 h (to 0.84 +/- 0.32 mmol/L), and then followed by a gradual increase. This study suggests that changes in serum ionized calcium in dehydrating gastroenteritis are not of clinical significance. However, changes in serum phosphate concentration need further evaluation.

An infant with high anal atresia and transverse colostomy, in whom initial radiologic evaluation of the urinary tract had been normal, developed hyperchloremic metabolic acidosis at 24 days of age. Gastroenteritis and renal tubular acidosis as possible causes for this metabolic disturbance were excluded, which prompted a repeat investigation of the possibility of a communication between the urinary tract and the rectum. A recto-urethral fistula was demonstrated by urethrography. Analysis of the fluid obtained from the left colon as compared to urine in the bladder and voided urine demonstrated that electrolyte exchange was taking place in the colon, resulting in hyperchloremic hypokalemic acidosis. Treatment with oral sodium bicarbonate and daily lavage of the left colon resulted in normalization of the acid-base status and catch-up growth of the baby. Hyperchloremic acidosis associated with anal atresia and recto-urinary communication appears to be uncommon. However, early diagnosis and treatment of the metabolic derangement are of importance as it may determine the infant's overall prognosis.

Ciguatera is the commonest form of poisoning resulting from eating fish in the tropics. It has been recognised since the 15th century. The disease is due to the formation of ciguatoxin by a dinoflagellate, Gambierdiscus toxicus, loosely attached to algae growing on coral reefs. The toxin, which is harmless to the fish, is ingested by small herbivorous fish and passes up the food chain as these are eaten by carnivores. The toxic effects include gastroenteritis, itching of the skin, peripheral neuropathy and central nervous system dysfunction. Though most cases are mild, occasionally the disease is severe and even fatal. There is no effective specific treatment. Three cases, of which one died and which exhibited both peripheral and central nervous system involvement, are described. Histological changes in sural nerve fibers are described. There was striking oedema of the adaxonal Schwann cell cytoplasm. These histological changes are very similar to those seen following the injection of scorpion and spider venoms into the peripheral nerve of experimental animals. Both these venoms and ciguatoxin increase the permeability of the membrane to sodium.

Sixty well-nourished, well-hydrated infants, 3 to 24 months of age with uncomplicated acute gastroenteritis, were enrolled in a prospective, randomized, double-blind study that compared the safety and efficacy of two oral solutions. The solutions differed primarily in the sodium concentration (60 v 30 mEq/L) and glucose concentration (2% v 5%). The mean serum sodium concentrations of the two groups did not differ significantly from each other at entry or at the end of the study period. In addition, there were no significant changes in the mean serum sodium concentration within each group at the end of the study period. No child in either group became hypernatremic. Our results indicate that a solution with a high concentration of sodium initially designed for the rehydration of dehydrated children also can be safely and effectively used as a maintenance solution for the treatment of well-hydrated children older than 3 months of age with acute gastroenteritis.

A controlled, randomised trial comparing the results of oral rehydration therapy with those of intravenous fluid treatment in 470 children with severe gastroenteritis was undertaken. The oral rehydration therapy was divided into two phases--a rehydration phase that used high sodium isotonic fluid at 40 ml/kg per hour and a maintenance phase using low sodium isotonic fluid (sodium 40, potassium 30, bicarbonate 25, chloride 45, and dextrose 130 mmol/l). The results indicate that oral rehydration treatment, used according to this protocol, is successful in treating severe diarrhoea and dehydration, and has considerable advantages over intravenous fluid therapy in reducing complications associated with the treatment of hypernatraemia, in promoting rapid correction of hypokalaemia and acidosis, in decreasing the duration of diarrhoea, and in promoting a greater weight gain at hospital discharge.

Norfloxacin is one of the new 4-quinolone antibacterial agents. A fluorinated piperazinyl-substituted congener of nalidixic acid, it demonstrates a much wider in vitro antibacterial spectrum and greater potency than the parent compound. Its antibacterial activity against most Gram-negative pathogens is enhanced in comparison to nalidixic acid, but is similar to that of some of the other new 4-quinolones like enoxacin, and slightly less than that of ciprofloxacin. Unlike nalidixic acid, norfloxacin is also active against Pseudomonas aeruginosa and some Gram-positive organisms. In acute or uncomplicated urinary tract infections, norfloxacin has repeatedly been shown to be as effective as co-trimoxazole. Single studies have demonstrated a significantly better bacteriological cure rate with norfloxacin than with pipemidic acid, and similar cure rates with norfloxacin and both a nalidixic acid/sodium citrate mixture and amoxycillin. Similar results were found in a few studies comparing norfloxacin to pipemidic acid or amoxycillin in patients with chronic and/or complicated urinary tract infections. Norfloxacin is as effective as spectinomycin in gonorrhoea due to penicillin-resistant N. gonorrhoeae, and cures bacterial gastroenteritis caused by several gastrointestinal pathogens. Norfloxacin appears to be well tolerated and may have a low propensity to select for bacterial resistance during clinical use, although the latter needs further confirmation.

To investigate the effect of chronic protein-calorie malnutrition on intestinal repair after an enteric infection, we examined small intestinal structure, enzyme activity, and sodium transport in undernourished piglets during the acute and convalescent phases of a viral enteritis, transmissible gastroenteritis (TGE). Gnotobiotic pigs, nutritionally deprived from the age of 7 days, gained less weight than dietary controls from 14 days of age until the end of the study. Animals from malnourished and control diet groups were inoculated with TGE virus at 22-23 days and studied during the acute (40 h) and convalescent (4, 10, and 15 days) stages of this experimental enteritis along with noninfected dietary controls. After TGE infection, we observed a further decrease in weight gain and an increased mortality only in undernourished pigs. In jejunum and ileum of both dietary groups at 40 h after TGE infection, we observed comparable structural lesions, similar decreased activities of mucosal enzymes (sucrase, lactase, sodium-potassium-dependent ATPase), and increased thymidine kinase activities. Also we noted comparable diminution of glucose-stimulated jejunal sodium absorption in both dietary groups at 40 h. In control diet pigs, transport abnormalities recovered by 4 days after TGE infection and normal mucosal structure and enzyme activity returned over 4-15 days. In undernourished piglets, structural repair and enzyme abnormalities were prolonged when compared with the control diet group; glucose-stimulated sodium transport did not recover until 10 days after infection and never regained the enhanced activity seen in noninfected undernourished controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Eighteen infants with severe hypernatremic dehydration secondary to acute gastroenteritis were rehydrated during the 1st day with an oral glucose electrolyte solution containing 60 mmol sodium/L at a mean rate of 120 ml/kg/24 h. These 18 children were safely treated with oral therapy alone. No convulsions were observed during treatment. The mean decrease in natremia was 0.32 mmol/L/h, which compared favorably with the mean fall in natremia of 26 other infants in similar initial conditions who were treated intravenously. The present study lends additional support to the opinion that a slow decrease in plasma sodium (less than 0.5 mmol/L/h) helps to avoid seizures during treatment. As no other untoward effects were observed, this study also confirms that oral solutions given at a slow rate can effectively replace intravenous fluids in the majority of such children.
