A Clinical Trial to Evaluate the Safety and Immunogenicity of Norovirus Bivalent Vaccine
Norwalk GastroenteritisNorovirus InfectionsA total of 450 subjects were enrolled, divided into four age groups, including 18-59 years, 6-17 years, 3-5 years, and 6-35 months. There are three types of the test vaccine component in each age group. A total of 30 people in each dose group were vaccinated with the test vaccine or placebo 1 or placebo 2, respectively, in a ratio of 3: 1: 1. The 18-59-year-old, 6-17-year-old, and 3-5-year-old age groups were vaccinated 2 times at a time interval of 28 days. The 6-35 month age group is divided into two groups, Group 1 is inoculated with 2 doses interval of 28 days each, and Group 2 is inoculated with 3 doses interval of 28 days.

Impact of Systematic Infants Vaccination Against Rotavirus on Gastroenteritis Hospitalization: a...
Rotavirus GastroenteritisUniversal rotavirus vaccination program for infants born in Brest after February 2007, applied by the Centers for Maternal and Infant Health Protection, pediatricians and general practitioners. Prospective surveillance of hospitalizations for gastroenteritis within the Pediatric Units of Brest University Hospital with systematic testing for Rotavirus. Evaluation of the impact of the vaccination program on rotaviral gastroenteritis hospitalizations from 2007-2008 and 2008-2009, by comparison with epidemiological data from 2002-2007 in the absence of vaccination. The principal judgement criterion is the number of pediatric hospitalizations for rotaviral GEA during the 2008-2009 epidemic in children A) under the age of 2 and B) residing in the suburbs of Brest.

Evaluation of Recombinant Norovirus Hexavalent Vaccine in Healthy Subjects
GastroenteritisTo evaluate the safety and immunogenicity of different dose levels of the Recombinant Norovirus Hexavalent Vaccine in healthy subjects aged 18-59 years given three doses of the vaccine at 28-day intervals.

Phase I Study to Determine the Optimal Human Challenge Dose for a Norovirus GII.4 Challenge Stock...
Gastroenteritis NorovirusThis is phase I, double blind, placebo-controlled safety and infectivity study of experimental human Norovirus genogroup GII.4 administered to healthy adults 18-49 years of age. Subjects susceptible to the human norovirus GII.4 challenge strain. The challenge study will be conducted in 2-3 cohorts of approximately 20 subjects each.Subjects will remain in the inpatient facility for at least four days following challenge and assessed daily for clinical and virologic evidence of norovirus infection. The primary objectives are to evaluate the safety and reactogenicity of the norovirus GII.4 (CIN-1; 031693) challenge stock and to determine a safe and optimal challenge dose of Norovirus GII.4 Challenge Stock norovirus to achieve illness in > /=50% of subjects. Illness is defined as: diarrhea (>3 loose or liquid stools or >300 gm of loose or liquid stool /24h), and/or vomiting during the inpatient period, in a participant with evidence of infection.

Video Discharge Instructions for Pediatric Gastroenteritis in an Emergency Department
Acute GastroenteritisVideo discharge instructions (VDI) have been suggested as a useful strategy to improve discharge instructions in pediatric emergency units. The goal of this study is to evaluate if the addition of VDI to usual verbal information improved the comprehension of information provided to caregivers of patients who consult for acute gastroenteritis (AGE). An open-label, parallel, randomized trial was designed, enrolling patients who consult for AGE. First, caregivers answer a written test concerning AGE characteristics and management. They are randomly allocated to a control group, which receives verbal discharge instructions, or to an intervention group, which additionally receives video discharge instructions. After discharge, caregivers are contacted by telephone and answer the same test. Main outcome measure is difference between test scores in the first and the second tests, secondary endpoints are how many caregivers score 5/5 on the second test, as well as rate of return visits and caregivers satisfaction with the information received.

Impact of Rotavirus Vaccination on Hospital Pressures at a Large Paediatric Hospital in the UK:...
GastroenteritisThe impact of rotavirus vaccination on the burden of disease has been well documented. However, the anticipated reduction in hospital pressures has yet to be described. This study will provide quantitative measures of hospital pressure prior to and post vaccine introduction, provide a template for future hospital pressures studies related to vaccine introduction and provide measures which could be used in an economic evaluation.

Glycan Attachment Specificity, Toward ROtavirus Vaccine IMprovement GASTROVIMc (Clinical Investigation)...
GastroenteritisAcute GastroenteritisThe GASTROVIM research explores the links between individual genetic susceptibility, genetic variability of rotavirus strains and effectiveness of immunization with the rotavirus vaccination: a clinical investigation to assess glycan attachment specificity, toward rotavirus vaccine improvement.

Continuous Enteral Rehydration by Nasogastric Tube With ORS in Children With Acute Gastroenteritis...
Acute GastroenteritisDehydrationWhen oral rehydration is impossible, enteral rehydration via the nasogastric route has been the recommended method of rehydration since 2008 by ESPGHAN ( European Society for Paediatric Gastroenterology Hepatology and Nutrition ), for children with acute gastroenteritis. However, these recommendations are rarely followed in France. These recommendations were not applied in the Children's Emergency Department of BREST University Hospital. The investigators changed the protocol and shared it with the caregivers of the emergency unit. The investigators studied the impact of this change of protocol
