REVIEW
Thad Wilkins, Jacqueline Sequoia
Probiotics contain microorganisms, most of which are bacteria similar to the beneficial bacteria that occur naturally in the human gut. Probiotics have been widely studied in a variety of gastrointestinal diseases. The most-studied species include Lactobacillus, Bifidobacterium, and Saccharomyces. However, a lack of clear guidelines on when to use probiotics and the most effective probiotic for different gastrointestinal conditions may be confusing for family physicians and their patients. Probiotics have an important role in the maintenance of immunologic equilibrium in the gastrointestinal tract through the direct interaction with immune cells...

REVIEW

After acute infectious gastroenteritis, up to thirty percent of patients present prolonged gastrointestinal symptoms and a part of those affected patients can have the diagnostic criteria for postinfectious irritable bowel syndrome. Treatment is symptom directed rather than curative and includes agents prescribed for the treatment of irritable bowel syndrome in general. Prophylaxis or early treatment of acute bacterial diarrhea may reduce the risk of postinfectious irritable bowel syndrome development by reducing the occurrence, duration, and severity of the chronic inflammation and mucosal alterations (all these believed to play an important role in disease persistence)...

BACKGROUND: Acute gastroenteritis is a common cause of morbidity and mortality in humans worldwide. The rapid and specific identification of infectious agents is crucial for correct patient management. However, diagnosis of acute gastroenteritis is usually performed with diagnostic panels that include only a few pathogens. In the present bicentric study, the diagnostic value of FilmArray™ GI panels was assessed in unformed stool samples of patients with acute gastroenteritis and in a series of samples collected from pediatric patients with heamorragic diarrhea...

In areas lacking potable water treatment, drinking contaminated water may represent a public health threat. In addition to enteropathogenic bacteria and parasites, fecal contamination in water environments is associated with the transmission of enteric viruses and other causal agents of infectious disease. Rotavirus and norovirus are the main enteric viral agents responsible for diarrheic outbreaks. The aim of the present study was to detect seasonal variation of rotavirus and norovirus in the surface water at Bassaseachic Falls National Park during 2013...

BACKGROUND Acute diarrhea is the second most common cause of morbidity and mortality worldwide, especially in children aged ≤3 years. Some drugs (e.g., the mucoprotector gelatin tannate) plus a reduced osmolality oral rehydration solution (ORS) may effectively reduce symptom duration and severity. The current trial was therefore designed to assess the efficacy and safety of gelatin tannate in pediatric patients with acute diarrhea. MATERIAL AND METHODS This was a randomized, controlled, double-blind, parallel-group, single-center study comparing gelatin tannate plus ORS (103 patients) with ORS plus placebo (100 patients) in children aged 3 months to 12 years with infectious or noninfectious acute diarrhea...

We report on the course of disease in a young woman, originally admitted with suspected refractory infectious tropical traveler's diarrhea. However, symptoms did not resolve upon either symptomatic or subsequent antibiotic therapy. When neurologic deterioration was observed, imaging studies revealed a dramatic series of thromboembolic events, including intracranial hemorrhage caused by extensive sinus vein thrombosis as well as thrombi of the right cardiac ventricle. Colonic mucosal biopsy samples finally led to the histologic diagnosis of ulcerative colitis...

In a global world, knowledge of imported infectious diseases is essential in daily practice, both for the microbiologist-parasitologist and the clinician who diagnoses and treats infectious diseases in returned travelers. Tropical and subtropical countries where there is a greater risk of contracting an infectious disease are among the most frequently visited tourist destinations. The SEIMC considers it appropriate to produce a consensus document that will be useful to primary care physicians as well as specialists in internal medicine, infectious diseases and tropical medicine who help treat travelers returning from tropical and sub-tropical areas with infections...

Bats are natural reservoirs for many pathogenic viruses, and increasing evidence supports the notion that bats can also harbor group A rotaviruses (RVAs), important causative agents of diarrhea in children and young animals. Currently, 8 RVA strains possessing completely novel genotype constellations or genotypes possibly originating from other mammals have been identified from African and Chinese bats. However, all the data were mainly based on detection of RVA RNA, present only during acute infections, which does not permit assessment of the true exposure of a bat population to RVA...
