Dientamoeba fragilis is an intestinal protozoan of debated clinical significance. Here, we present cross-sectional and longitudinal observations on D. fragilis in children aged 0-6 years from a 1-year multi-day-care-center cohort study set in Copenhagen, Denmark. The inclusion period for the cohort was 2009-2012. Stool samples collected from the children were accompanied by questionnaires completed by the parents or guardians of the children. Using real-time PCR, D. fragilis was detected in the first stool sample from 97 (68...

INTRODUCTION: Vaccination against Salmonella Typhi is one of the leading public health interventions reducing the risk of typhoid fever. There are two available licensed vaccines, Vivotif, oral live-attenuated, and Typhim Vi, intramuscular Vi capsular polysaccharide. The US military is a high risk travel population commonly vaccinated for S. Typhi. We describe the use of S. Typhi vaccination in this population and the acute reactogenicity profile of these vaccines. METHODS: Data were obtained from the Defense Medical Surveillance System and vaccination identified between 1998 and 2011 from vaccination codes...

BACKGROUND: In times of mass tourism, traveler's diarrhea is one of the most common health problems of long-distance travel. Globally, some 40 million cases occur annually. Travellers to risk areas should therefore be comprehensively advised beforehand, as to what action to take in case of an acute traveler's diarrhea and what drugs to add to their first-aid kit. To date none, or hardly any specific studies or valid specific guidelines for the treatment of traveler's diarrhea are available for Germany...

BACKGROUND: Adjunctive automated whole blood or red blood cell exchange (RBCEx) can rapidly decrease malarial hyperparasitemia. Several case reports and series suggest improvement in clinical symptomatology; however, recent Centers of Disease Control and Prevention (CDC) recommendations concluded that RBCEx has no efficacy as an adjunctive therapy. We present a case of mental status changes secondary to cerebral malaria treated with automated RBCEx resulting in rapid and dramatic neurologic improvement...

Autoimmune enteropathy (AIE) is rare but damaging. The lack of consistent objective findings makes diagnosis a challenge. A 45-year-old male developed noninfectious diarrhea with significant weight loss and electrolyte abnormalities. Computed tomography delineated enteritis. Colonoscopy and esophagogastroduodenoscopy showed villous atrophy, chronic inflammation, and ulceration of the terminal ileum and cecum. Pathology showed cryptitis with apoptosis and abscesses throughout the small and large bowel and absent goblet cells...

In Cusco, Peru, and South America in general, there is a dearth of travelers' diarrhea (TD) data concerning the clinical features associated with enteropathogen-specific infections and destination-specific risk behaviors. Understanding these factors would allow travel medicine providers to tailor interventions to patients' risk profiles and travel destination. To characterize TD etiology, evaluate region-specific TD risk factors, and examine relationships between preventive recommendations and risk-taking behaviors among medium- to long-term travelers' from high-income countries, we conducted this case-case analysis using 7 years of prospective surveillance data from adult travelers' presenting with TD to a physician in Cusco...

A 5-year-old nonverbal child with autism spectrum disorder (ASD) was admitted to inpatient pediatrics with new onset agitation and self-injurious behavior. His parents described him as a pleasant child without previous episodes of self-injury. Four days before admission, the parents noted new irritability followed by 2 days of self-injury to the face without clear precipitant. His hitting intensified with closed fist to face, and he required parental physical restraint to prevent further injury. Car rides and ibuprofen provided only temporary relief...

Enterotoxigenic Escherichia coli (ETEC) is a non-invasive enteric pathogen of considerable public health importance, being one of the most common attributable causes of diarrheal illness in infants and young children in developing countries and the most common cause of traveler's diarrhea. To enhance study-to-study consistency of our experimental challenge model of ETEC in volunteers, and to allow concomitant multi-site trials to evaluate anti-ETEC immunoprophylactic products, hundreds of vials, each containing a standardized inoculum of virulent wild-type (wt) ETEC strain H10407 (serotype O78:H11 expressing colonization factor antigen I and heat-labile and heat-stable enterotoxins), were prepared under current Good Manufacturing Practices (cGMP) and frozen...

Enterotoxigenic Escherichia coli (ETEC) can be attributed to around 200 million diarrheal episodes and 380,000 deaths in the developing regions. Travelers' diarrhea occurs in 15-40% of travelers to developing regions with ETEC being the most important etiologic agent. This study aims to describe the distribution of enterotoxins and colonization factor (CF) profiles of ETEC isolates from stool samples of adult travelers acquiring diarrhea in Mexico, Guatemala, and India and a group of children with acute diarrhea in Houston, TX, between 2007 and 2012...

BACKGROUND: Enterotoxigenic Escherichia coli (ETEC) is a major cause of diarrhea in children and travelers to endemic areas. Secretion of the heat labile AB5 toxin (LT) is induced by alkaline conditions. In this study, we determined the surface proteome of ETEC exposed to alkaline conditions (pH 9) as compared to neutral conditions (pH 7) using a LPI Hexalane FlowCell combined with quantitative proteomics. Relative quantitation with isobaric labeling (TMT) was used to compare peptide abundance and their corresponding proteins in multiple samples at MS/MS level...

La diarrea aguda es la enfermedad más común que afecta a los viajeros, principalmente aquellos que se dirigen a regiones de alto riesgo. El uso de probióticos podría prevenir su aparición, sin embargo, los datos que apoyan su uso no son consistentes y no se recomiendan en las guías clínicas actuales. Utilizando la base de datos Epistemonikos, la cual es mantenida mediante búsquedas en múltiples bases de datos, identificamos cuatro revisiones sistemáticas que en conjunto incluyen siete estudios aleatorizados pertinentes a esta pregunta...

Enterotoxigenic Escherichia coli (ETEC) strains are among the most common causes of children's diarrhea and travelers' diarrhea. Developing effective vaccines against ETEC associated diarrhea becomes a top priority. ETEC heat-labile toxin (LT) and heat-stable toxin (STa) toxoid fusion 3xSTaN12S-dmLT was demonstrated recently to induce neutralizing antitoxin antibodies in intraperitoneally or subcutaneously immunized mice. However, whether antibodies derived from this toxoid fusion are protective against ETEC diarrhea has not been examined...

Enterotoxigenic Escherichia coli (ETEC) are a major cause of traveler's diarrhea and infant mortality in developing countries. Given the rise of antibiotic resistance worldwide, there is an urgent need for the development of new preventive strategies. Among them, a promising approach is the use of probiotics. Although many studies, mostly performed under piglet digestive conditions, have shown the beneficial effects of probiotics on ETEC by interfering with their survival, virulence or adhesion to mucosa, underlying mechanisms remain unclear...

Key components of the pretravel consultation include intake questions regarding the traveler's anticipated itinerary and medical history; immunizations; malaria prophylaxis; and personal protection measures against arthropod bites, traveler's diarrhea, and injury. Most vaccinations that are appropriate for international travelers are included in the routine domestic immunization schedule; only a few travel-specific vaccines must also be discussed. The most common vaccine-preventable illnesses in international travelers are influenza and hepatitis A...

Histoplasmosis is well characterized as an endemic fungal disease restricted to certain areas of the USA. In Middle Europe, most patients present with acute pulmonary symptoms after travelling to endemic areas. Here, we want to illustrate the case of a 67-year-old man who presented with persistent oral ulcers, hoarseness, dysphagia, diarrhea, and weight loss to our Department of Otorhinolaryngology in December 2014. He was a retired construction worker and had a history of soil-disruptive activities in Africa and Middle and South America during employment...
