The purpose of this study was to establish the concepts of the drugstore salesforce on the management of acute diarrhea in children. The study was carried out in Guatemala by means of a direct interview of 427 employees of an equal number of drugstores, that were representative of the total drugstores in the country. The results showed that one third of the employees only have grammar education or less, that they were young adults without training in medicine or drug therapy, and that it frequent that people ask for medication for diarrhea in children. For food during diarrhea, fat, milk, meat and beans were mentioned as bad foods, and starch gruels, vegetables and soups were mentioned as good food. From the total sample 82.4% stated that antibiotics are indicated always or almost always, 69.8% prescribe antidiarrheicals as caolin/pectine alone or in combination with antibiotics or sulfonamides, and 33.0% prescribe antibiotics, being ampicillin, chloramphenicol and cotrimoxazole the more common; 73.5% prescribe oral rehydration, but only 8.7% of drugstores have oral rehydration salts recommended by WHO/UNICEF. Based on these results it is recommended to establish a longitudinal program in order to train this group of people who are in primary care, on the management of acute diarrhea in children.

The fortuitous finding that Aeromonas spp. grew well on Butzler Campylobacter selective medium (BCSA) in a microaerobic atmosphere at 42 degrees C prompted us to evaluate the performance of BCSA for selective isolation of aeromonads in comparison with ampicillin (30 micrograms/ml) sheep blood agar (ASBA30). Overall recovery rates of aeromonads from 563 stool samples from patients with acute diarrhea were higher on ASBA30 (70.4%) than on BCSA (56.3%); however, 21 (29.5%) grew only on BCSA. The three human-associated Aeromonas spp. could be recovered on BCSA and ASBA30. We recommend the use of BCSA to laboratories reluctant to include a specific selective medium for aeromonads.

Salmonella was the most frequent bacterial pathogen isolated from patients with acute diarrhoea in Hong Kong. In Queen Mary Hospital, the major hospital on Hong Kong Island, 94.7% of salmonellae isolated from faecal specimens from patients during the period 1973-82 belonged to the gastroenteric group, while 5.3% belonged to the enteric fever group. Amongst the gastroenteric group, 68 salmonella serotypes were identified, with Salmonella derby, S. typhimurium and S. anatum being the predominant ones. Three outbreaks caused by S. johannesburg, S. worthington and S. wandsworth were detected. Of S. typhimurium, 61.6% were resistant to multiple antibiotics and belonged to four major phage types: 193, 22, 138 and U288. The majority (96.8%) of S. johannesburg strains which caused a widespread epidemic were multiply-resistant. Multiple antibiotic resistance was rarely observed in most other gastroenteric salmonellae. S. typhi was the commonest of the enteric fever group isolated from the blood of patients. Nineteen phage types were identified; E1 being the commonest (18.5%) while 21% were nontypable. Many of these isolated were resistant to streptomycin or sulphadiazine, but none were resistant to ampicillin, chloramphenicol or trimethoprim.

Five selective media were evaluated for their effectiveness in the primary isolation of Aeromonas spp. from human patients with acute diarrhea and from healthy domestic animals. Sheep blood agar with 30 mg of ampicillin per liter (ASBA30) yielded a significantly higher percentage of positive specimens as compared with the four other media. The effective combination of two selective media with which 98% of all isolates were detected and with which all of the three human-associated Aeromonas spp. could be isolated was ASBA30-DNase-toluidine blue agar. ASBA30 was the most sensitive medium since it permitted more growth of Aeromonas colonies and effectively suppressed competing microflora. We recommend the use of ASBA30-DNase-toluidine blue agar for investigations in which an attempt is made to assess the significance of Aeromonas spp. in the etiology of human diarrhea.

Various available forms of therapy can decrease morbidity and mortality associated with acute diarrhea. Oral fluids represent the cornerstone of therapy of all cases. A variety of agents acting nonspecifically can decrease diarrhea and improve other worrisome symptoms associated with enteric infection. Kaopectate makes the stool more formed but has little additional effects. Bismuth subsalicylate, an antisecretory agent, reduces the number of stools passed by about 50 percent and improves other associated symptomatology. The drugs that affect motility such as loperamide and diphenoxylate are the most active of the nonspecifically acting drugs. They must be avoided in patients with significant fever and dysentery. Trimethoprim/sulfamethoxazole is now considered the drug of choice for shigellosis due to the presence of ampicillin-resistant Shigella strains in most regions of the world. Trimethoprim/sulfamethoxazole is also an effective form of therapy for enterotoxigenic Escherichia coli infection and for traveler's diarrhea without definable cause. Erythromycin, although not proved to be effective against Campylobacter, probably shortens the disease. Furazolidone, although not dramatically effective, has a spectrum of activity that includes Shigella, enterotoxigenic E. coli, Campylobacter, and Giardia lamblia. It may not be effective in severely ill (hospitalized) patients with diarrhea. The various forms of available therapy can be administered empirically, depending on symptomatology. Mildly ill patients (one to three unformed stools in 24 hours with minimal additional symptoms) probably are best treated with fluids only. Mild to moderately ill persons (three to six unformed stools in 24 hours) can be treated with a drug that acts nonspecifically, such as bismuth subsalicylate or loperamide. Those with severe diseases (six or more unformed stools with moderate to severe associated symptoms), particularly when associated with fever and the passage of bloody mucoid stools, may be given an antimicrobial agent. The antimicrobial drug given will be determined by ancillary laboratory tests (dark-field examination or examination of a wet-mount preparation for motile Campylobacter or stool culture for Shigella, Campylobacter, or Salmonella) or may be administered on an empiric basis. Traveler's diarrhea can be eliminated in selected persons by the administration of a pharmacologic agent. Liquid bismuth subsalicylate is effective in large doses, which may be impractical. Studies with the tablet formulation suggest that it is partially effective in preventing the illness. Doxycycline and trimethoprim/sulfamethoxazole are more effective, particularly when admini

Empiric treatment with ciprofloxacin and norfloxacin has been recommended recently for patients with acute diarrhoeal disease. In a retrospective 6-month study period the results of stool cultures from 209 patients with acute diarrhoea admitted to the emergency room were analysed. Seventy-eight cultures (37%) were positive for one or more bacteria. Shigella was the most commonly isolated pathogen (68%). Shigella sonnei comprised 72% and Shigella flexneri 19% of all the bacterial isolates. While no antimicrobial resistance to ciprofloxacin was found for both Shigella species, only 36 and 26% of the Shigella isolates were sensitive to ampicillin and trimethoprim-sulfamethoxazole (TMP-SMZ), respectively. These findings point out to the emergence of drug resistance to commonly used antimicrobial drugs. Shigella's high sensitivity to the newer quinolones should make this the treatment of choice for the very sick patient, although physicians should be cautioned to the fact that indiscriminate use of this drug could result in the emergence of resistance similar to that noted with ampicillin and TMP-SMZ.

Clinical and laboratory studies on a total of 211 of infants and young children admitted to the National Santa Cruz General Hospital for various types of diarrhoea during 1991-1992 are described. A peak cluster was observed in children aged 1 year of which 80 per cent were acute diarrhoea and the remaining 20 per cent were prolonged or chronic diarrhoea. The major bacterial pathogen was enteropathogenic Escherichia coli. Other bacterial pathogens such as Klebsiella, Shigella, Cholera, etc., were detected. Ascaris, E. histolytica, Giardia and Ankylostoma were also detected. Many of the patients infected with enteropathogenic E. coli showed elevated serum titre to these bacterial antigens. Most of the detected E. coli and Shigella revealed that they were resistant to ampicillin, trimethoprim/sulfamethoxazole, and erythromycin, and some were resistant to gentamycin and chloramphenicol in vitro tests. It was difficult to make a diagnosis by clinical diagnosis alone for cholera of the el Tor Ogawa type. The detection of faecal leukocytes seems to be an useful predictor for diagnosis of invasive diarrhoea with mucobloody stools. Faecal pH and erythrocytes did not seem to be reliable diagnostic predictors. Fourteen cases (7 per cent) died of diarrhoeal disease. Many of them had complications with marked dehydration, hypoelectrolytaemia, malnutrition and infections, and rapid deterioration within 10 days despite rehydration therapy. Timely rapid rehydration and restoration of electrolytes followed by suitable management of complications are necessary.

As part of a multicenter collaborative study the relative frequency of enteropathogenic agents in children less than 5 years of age with acute diarrhea was determined. Rates of isolation were similar as regards sex, age, and season. The frequency of polymorphonuclear cells (PMN) in the stools was significantly higher among patients requiring admission in comparison with ambulatory patients. Enteropathogenic E. coli (EPEC) was isolated more frequently in that group in comparison with outpatients (p < 0.001), mainly among children less than 5 months of age. The most prevalent agents were EPEC (26.1%), enterotoxigenic E. coli (ETEC) (9.7%), Shigella (8.5%), Rotavirus (5.1%), Giardia (3.6%), Campylobacter (3.2%), and Salmonella (2.4%). The EPEC predominant serogroups were 0 111, 0 55, 0 26, and 0 119. ETEC serotypes 0 153:H45 and 0 128:H21 were more often isolated. The predominant species in the genus Shigella were S. flexneri (80.5%), and S. sonnei (9.5%); in the genus Campylobacter, the species were C. jejuni (81.3%), and C. coli (18.7%). Shigella was clearly related to the presence of PMN in the faeces, in children less than 5 months old. Campylobacter was more frequent in ambulatory patients more than one year of age. Rotavirus was found predominantly in autumn and winter. Salmonella and ETEC were more frequent in summer. Giardia was associated with weight loss. In about 10% of the cases there were simultaneous mixed isolations of two or more agents. Salmonella isolates were sensitive to the majority of antimicrobial agents probed. Many Shigella and E. coli were resistant to sulfamethoxazole-trimethoprim and ampicillin (40-80%). Nearly all enterobacteria were sensitive to gentamicin and norfloxacin.

Stool samples of 1488 children suffering from acute diarrhoea were studied for bacterial culture and sensitivity. Shigella culture was positive in 143 (10 per cent) children and 53 hospitalized children could be studied in detail. Thirty-six (68 per cent) children were under 2 years of age and peak prevalence was observed in summer months. Fever and diarrhoea were universal features; 96 per cent had blood and mucus in the stools, but 32 per cent started with watery diarrhoea lasting 1-3 days followed by dysentery. Two cases (4 per cent) had watery diarrhoea. Abdominal pain dehydration, and malnutrition were present in more than two-thirds of the cases. Central nervous systemic (CNS) manifestations, renal failure, respiratory manifestations, and subacute intestinal obstruction were seen in 45, 25, 17, and 5 per cent of cases, respectively. Shigella dysenteriae was the commonest organism grown in 57 per cent, followed by Shigella flexneri in 36 per cent, Shigella boydii in 4 per cent, and Shigella sonnei in 4 per cent cases. In the majority, the organisms were sensitive to neomycin (83 per cent), furazolidine (86 per cent), and cephaloridine (87 per cent), whereas Shigella strains were resistant to tetracycline in 93 per cent, ampicillin in 83 per cent, chloramphenicol in 91 per cent and cotrimoxazole in 66 per cent cases. Proctosigmoidoscopy was useful in defining the nature of mucosal lesion, to collect swabs for culture and biopsy specimen for histopathology. Four (8 per cent) cases had pseudomembrane and in two cases Clostridium difficile could be identified. Eight (15 per cent) cases died and two of them had shigellaemia.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of acute diarrhoea caused by Aeromonas trota (formerly HG 13 group) in a Spanish child is reported. The strain was isolated in the faeces using the CIN agar (cefsulodin-irgasan-novobiocin) culture media. The strain was initially identified as A sobria by the commercial GNI card and API 20E biochemical systems. The strain was, however, VogesProskauer and sucrose negative, so complementary tests of cellobiose fermentation and gluconate oxidation were performed. These tests, together with the strain susceptibility to ampicillin (MIC 1 microgram/ml) and carbenicillin (MIC < 16 micrograms/ml) led to the final identification of A trota. The microbiological characteristics of this new species and the principal tests required for its identification are presented. The isolation, for the first time, of A trota in the Mediterranean area confirms the suspected worldwide distribution of this species.
