Thirty children suffering from acute diarrhoea have been examined over a period of 10 months. Salmonellae were present in 16.6% of the cases, Campylobacter in 10%, E. coli in 60%, Rotavirus in 10%. The monthly incidence of the infections has been studied, verifying values which fall into line with those reported by other authors. It has also been observed that macroscopic blood, fecal leucocytes are present in diarrhoea by bacterial agents, while Kerry test is more indicative of infections by Rotavirus. We fall into line with those who believe that the "use of products without lactose should be reserved for selected cases".

Acute diarrhea is a common problem in children. Understanding the different pathologic processes that cause diarrhea, and the agents that are associated with those processes, can aid the clinician in predicting the etiology of the diarrhea in an individual patient. Small bowel involvement, most commonly caused by Rotavirus, produces a high incidence of vomiting, often before the onset of diarrhea, and large, watery, and relatively infrequent stools. Large bowel involvement, usually due to Campylobacter, Salmonella, or Shigella produces frequent, often bloody stools containing leukocytes. Treatment of diarrhea should be focused on correcting dehydration, principally with oral rehydration solutions containing appropriate concentrations of electrolytes and carbohydrates. Early refeeding, avoiding foods containing lactose, should be considered for most pediatric patients with acute diarrhea. Antimicrobial therapy should be reserved primarily for parasitic infectious, pseudomembranous enterocolitis, and the early stages of a Campylobacter dysentery. The etiology of acute pediatric diarrhea can be predicted in most patients and early, appropriate treatment can be instituted.

The efficacy of BW942C, a novel enkephalinlike pentapeptide antidiarrheal agent, was compared with the efficacy of trimethoprim-sulfamethoxazole (TMP-SMX) and the combination of the two agents in a placebo-controlled trial of the 72-h treatment of acute diarrhea. Subjects with diarrhea but without bloody stools or fever greater than 102 degrees F (38.9 degrees C) were enrolled. Administered to 134 U.S. adults with diarrhea that developed shortly after their arrival in Guadalajara, Mexico, BW942C was more efficacious than TMP-SMX in relieving diarrhea and cramps in the first 12 h of therapy, especially among subjects with diarrhea caused by enterotoxigenic E. coli. In the BW942C treatment group, 25% of subjects eventually took additional therapy because their diarrhea did not respond to BW942C alone. Neurological side effects such as dizziness and light-headedness occurred more frequently among BW942C-treated subjects. Therapy for 3 days with TMP-SMX provided lasting relief comparable with previously reported 5-day therapy. Use of the combination of both agents provided the benefits of prompt relief afforded by BW942C and lasting relief afforded by TMP-SMX. BW942C might prove to be an agent suitable for the treatment of acute diarrhea, with TMP-SMX reserved for treatment of those who do not respond adequately. The empiric use of the combination of BW942C and TMP-SMX appears appropriate for the treatment of severe nondysenteric disease.

Acute diarrhea in adults is a common problem encountered by family physicians. The most common etiology is viral gastroenteritis, a self-limited disease. Increases in travel, comorbidities, and foodborne illness lead to more bacteria-related cases of acute diarrhea. A history and physical examination evaluating for risk factors and signs of inflammatory diarrhea and/or severe dehydration can direct any needed testing and treatment. Most patients do not require laboratory workup, and routine stool cultures are not recommended. Treatment focuses on preventing and treating dehydration. Diagnostic investigation should be reserved for patients with severe dehydration or illness, persistent fever, bloody stool, or immunosuppression, and for cases of suspected nosocomial infection or outbreak. Oral rehydration therapy with early refeeding is the preferred treatment for dehydration. Antimotility agents should be avoided in patients with bloody diarrhea, but loperamide/simethicone may improve symptoms in patients with watery diarrhea. Probiotic use may shorten the duration of illness. When used appropriately, antibiotics are effective in the treatment of shigellosis, campylobacteriosis, Clostridium difficile, traveler's diarrhea, and protozoal infections. Prevention of acute diarrhea is promoted through adequate hand washing, safe food preparation, access to clean water, and vaccinations.

Probiotics are becoming increasingly important in basic and clinical research, but they are also a subject of considerable economic interest due to their expanding popularity. They are live micro-organisms which, when administered in adequate amounts, confer a health benefit to the host. From this very well-known definition, it is clear that, unlike drugs, probiotics might be useful in healthy subjects to reduce the risk of developing certain diseases or to optimise some physiological functions. They also may offer some advantages in already ill persons in relieving symptoms and signs, e.g. people with acute diarrhea. According to current definitions, probiotics should survive both gastric acid and bile to reach the small intestine and colon, where they exert their effects. Many of these are available in a lyophilized (freeze-dried) pill form, though some are available in yogurt or as packets (sachets), which can be mixed into non-carbonated drinks. The present review focuses on three main issues: 1) understanding why, at present, probiotics are so interesting for doctors and consumers; 2) reviewing the available data on probiotic use in digestive diseases, in particular irritable bowel syndrome (IBS), (prevention of) infectious diarrhea, inflammatory bowel disease (IBD), non-alcoholic fatty liver disease (NAFLD), and colorectal cancer (CRC); 3) highlighting the individual profile of Lactobacillus GG (LGG) in the above contexts, providing an assessment as well as recommendations on its use in gastro-intestinal tract (GIT) disorders. Research studies conducted in animals and humans with the main probiotics strains for GIT diseases, and published from the early 1990s to 2014 have been considered. PubMed, Medline and Ovid were the main sources adopted for data retrieving. The increasing attention on probiotics is a direct consequence of the improvement in the techniques for studying microbiota. Until recently, its composition has been analysed by culture-based methods that use differential media to select for specific populations of bacteria according to their metabolic requirements. Lactobacillus and Bifidobacterium species are by and large the most commonly used probiotics. Strictly speaking, however, the term "probiotic" should be reserved for live microbes that have been shown in controlled human studies to provide a health benefit. Taking into account patients suffering from the most common gastrointestinal diseases, in whose establishment the GI microbiota plays a key role, probiotics have to be considered as very promising agents, capable of beneficially modulating the intestinal ecosystem, which is perturbed in cases of dysbiosis. Although more clinical data are still needed to better assess the clinical relevance of probiotics, to date, procariota such as Bifidobacteria and Lactobacilli strains, and eucariota such as some Saccharomyces strains are among the most widely used agents in GIT disorders. LGG is a well-known probiotic strain that was isolated more than 20 years ago by Goldin and Gorbach from a faecal sample of a healthy adult, based on several selection criteria: high adhesion in vitro, high resistance against gastric acidity and high antimicrobial activity against pathogens such as Salmonella. In vivo studies have also shown a good persistence of LGG in the human GIT. Since its isolation, LGG has become one of the best clinically documented probiotic strains. A growing body of evidence suggests benefits such as prevention and relief of various types of diarrhoea, and treatment of relapsing Clostridium difficile colitis. Thus, with respect to both adaptation to the GIT and probiotic effects, LGG can be regarded as a prototypical probiotic strain.

Acute gastroenteritis is one of the most common infection among children. An estimated 500 million children suffer from the condition worldwide each year. In developed countries the course of acute infectious diarrhea is relatively mild, symptoms usually resolve spontaneously within few days. Unfortunately high mortality rate is still a heavyweight problem in countries with low economic development. Acute diarrhea is defined as a change of the consistency of stools to loose or liquid and/ or increase of an amount of defecations to more than 3 during a day. Other symptoms of gastroenteritis include fever, nausea and vomiting. The most common cause of AGE are viruses, with rotavirus being the most frequent agent. The diagnose is based on medical interview, that include mainly precise information about duration and characteristic of occurred symptoms and epidemiological data. The most important part of diagnostic and therapeutic management is dehydration's assessment, which determine the severity of AGE and is used as one of the factors that decide about hospital admission. The majority of patients can be treated in an outpatients settings, hospitalization should be reserved for those requiring enteral or parenteral rehydration. Oral rehydration with hypoosmolar fluids is standard first-line treatment. Other effective procedures include administration of probiotics (Lactobacillus GG , Saccharomyces boulardii), racecadotril and diosmectite as antidiarrheals and ondansetron reducing the intensity of nausea and vomiting. Antibiotherapy should be only considered in exceptional situations. Acute diarrhea is commonly known medical problem, which can be easily treated by following simple, well-defined rules.

Diarrhea is a leading cause of antibiotic consumption among children in low- and middle-income countries. While vaccines may prevent diarrhea infections for which children often receive antibiotics, the contribution of individual enteropathogens to antibiotic use is minimally understood. We used data from the Global Enteric Multicenter Study (GEMS) to estimate pathogen-specific incidence of antibiotic-treated diarrhea among children under five years old residing in six countries of sub-Saharan Africa and South Asia before rotavirus vaccine implementation. GEMS was an age-stratified, individually-matched case-control study. Stool specimens were obtained from children presenting to sentinel health clinics with newly-onset, acute diarrhea (including moderate-to-severe and less-severe diarrhea) as well as matched community controls without diarrhea. We used data from conventional and quantitative molecular diagnostic assays applied to stool specimens to estimate the proportion of antibiotic-treated diarrhea cases attributable to each pathogen. Antibiotics were administered or prescribed to 9,606 of 12,109 moderate-to-severe cases and 1,844 of 3,174 less-severe cases. Across all sites, incidence rates of clinically-attended, antibiotic-treated diarrhea were 12.2 (95% confidence interval: 9.0-17.8), 10.2 (7.4-13.9) and 1.9 (1.3-3.0) episodes per 100 child-years at risk at ages 6 weeks to 11 months, 12-23 months, and 24-59 months, respectively. Based on the recommendation for antibiotic treatment to be reserved for cases with dysentery, we estimated a ratio of 12.6 (8.6-20.8) inappropriately-treated diarrhea cases for each appropriately-treated case. Rotavirus, adenovirus serotypes 40/41, Shigella, sapovirus, Shiga toxin-producing Escherichia coli, and Cryptosporidium were the leading antibiotic-treated diarrhea etiologies. Rotavirus caused 29.2% (24.5-35.2%) of antibiotic-treated cases, including the largest share in both the first and second years of life. Shigella caused 14.9% (11.4-18.9%) of antibiotic-treated cases, and was the leading etiology at ages 24-59 months. Our findings should inform the prioritization of vaccines with the greatest potential to reduce antibiotic exposure among children.
