ABSTRACT

OBJECTIVE: The survey was implemented to describe vaccination policies for healthcare professionals in French healthcare institutions. METHODS: A cross-sectional survey based on questionnaires was sent to occupational physicians and chairpersons of hospital infection prevention and control committees (HIPC) of 38 institutions between November 2010 and January 2011. RESULTS: Twenty-nine occupational physicians and 26 hospital infection prevention and control committees chairpersons (HIPC), from 30 institutions answered (response rate: 79%), 70% of the institutions were university hospitals. Overall, 76% of occupational physicians and 85% of HIPC chairpersons reported that information and awareness campaigns about vaccination recommendations for healthcare professionals were usually conducted in their establishment. Fifty-nine percent of occupational physicians and 31% of HIPC chairpersons reported that they were aware of the vaccine coverage rates of professionals in their institution. The occupational physicians reported that they suggested diphtheria, tetanus, polio, influenza, and acellular pertussis vaccination to all staff at their annual visit in 100%, 97%, and 62% of cases, respectively. Varicella and measles vaccinations were never suggested in 31% and 17% of cases, respectively. Among respondents, 55% of physicians reported that they had already managed a pertussis epidemic, and 42% a measles epidemic, and in both of these cases an awareness campaigns were usually conducted (93% and 96%). CONCLUSIONS: The vaccine coverage rates of healthcare professionals in French healthcare institutions remain insufficiently documented and could be improved.

ABSTRACT

The annual meeting of the Infectious Disease Society of America (IDSA) ; which brought together nearly 5000 participants from over 80 countries in Vancouver, Canada, October 21 to 24, 2010 ; provided a review of the influenza (H1N1) 2009 pandemic, evaluated vaccination programmes and presented new vaccines under development. With 12,500 deaths in the United States in 2009-2010, the influenza (H1N1) 2009 pandemic was actually less deadly than the seasonal flu. But it essentially hit the young, and the toll calculated in years of life lost is high. The monovalent vaccines, whether live attenuated or inactivated with or without adjuvants, were well tolerated in toddlers, children, adults and pregnant women. In order to protect infants against pertussis, family members are urged to get their booster shots. The introduction of the 13-valent Pneumococcal conjugated vaccine in the beginning of 2010 may solve - but for how long ? - the problem of serotype replacement, responsible for the re-increasing incidence of invasive Pneumococcal infections observed in countries that had introduced the 7-valent vaccine. The efficacy of a rotavirus vaccine has been confirmed, with a reduction in hospitalization in the United States and a reduction in gastroenteritis-related deaths in Mexico. In the United States, vaccination of pre-adolescents against human papillomavirus (HPV) has not resulted in any specific undesirable effects. Routine vaccination against chicken pox, recommended since 1995, has not had an impact on the evolution of the incidence of shingles. Vaccination against shingles, recommended in the United States for subjects 60 years and over, shows an effectiveness of 55 %, according to a cohort study (Kaiser Permanente, Southern California). Although some propose the development of personalized vaccines according to individual genetic characteristics, the priority remains with increasing vaccine coverage, not only in infants but also in adults and the elderly. Vaccine calendars that cover a whole lifetime should be promoted, since the vaccination of adults and seniors is a determining factor of good health at all ages.

ABSTRACT

OBJECTIVE: A literature review was made to answer the following question: are there differences in immunogenicity and safety of vaccines according to the administration route (intramuscular or subcutaneous) and the length of needles used for injection? DESIGN: The search strategy included electronic searching (Medline database via PubMed) and cross-references. Articles were selected by reading abstracts, guided by the clinical question. A total of 18 articles were selected and analyzed; 13 answered the question. RESULTS: Nine articles compared the immunogenicity and/or the safety of a given vaccine administered via both intramuscular and subcutaneous routes. All the results showed that immunogenicity and systemic safety of the intramuscular route was at least as good as that of the subcutaneous route. Local tolerance was usually better via intramuscular route (lower risk of developing erythema or edema). Four articles compared the immunogenicity and the safety of vaccines administered with short (16mm) and long (25mm) needles in children. Long needles induced fewer local reactions, probably because they can reach more vascularized muscle, especially in overweight and obese patients. CONCLUSIONS: Immunogenicity and safety results are in favor of intramuscular vaccination. The appropriate needle length must to be adapted according to the morphological aspects (subcutaneous tissue and muscle thickness).

ABSTRACT

OBJECTIVE: The aim of this study was to assess the burden of medical and paramedical activities related to the management of acute gastroenteritis (AGE) cases in France. METHODS: An observational, multicenter study was carried out in 23 French pediatric emergency units. Each unit was requested to include the first 25 children less than five years of age, consulting for AGE during the epidemic season. RESULTS: A total of 443 children was included between January and April 2007. The median age was 13 months. Symptoms had been persisting for an average of 2.7 days, and 60.7% of patients had already consulted. In 62.6% of cases, oral rehydration solution (ORS) had been prescribed. The median waiting time in the EU was 15 minutes. The median time spent by a health care professional with a child was 55 minutes (30 minutes for paramedical care and 25 minutes for medical care). The length of these visits increased significantly (p<0.0001) if children presented with signs of dehydration or behavioral changes. The child's age had no significant impact. Rehydration in the EU was 70% oral rehydration, 16% parenteral rehydration (8% were combined). Among the children, 37% were discharged after consultation in the EU, 39% after observation, and 24% were hospitalized. 90% of the children who were given a prescription on discharge were prescribed at least one ORS (n=333). CONCLUSION: The time spent by a health care professional with a child presenting with acute gastroenteritis could cause organizational problems during an epidemic outbreak.

ABSTRACT

Demineralized bone matrix (DBM) has been investigated as a bone graft substitute for spinal fusion with less morbidity. Various carriers have been added to DBM to enhance its handling characteristics. This study investigates the spinal fusion induced by a composite of DBM and acellular dermal matrix (AM) in comparison with autologous bone in an athymic rat spinal fusion model. Single-level intertransverse process fusions were performed in 60 athymic nude rats grafted with 2 mL/kg of DBM/AM composite, AM alone, or autologous bone. Fusion was assessed at 6 weeks by radiography, manual palpation, and histology. At 6 weeks, 70% of the animals from the DBM/AM composite group exhibited complete spine fusion, whereas 35% from the autologous bone group and 20% from AM group showed bridging with some gaps. The DBM/AM composite induced a significantly higher fusion rate than both the autologous bone and AM groups (p < 0.001) in all measured parameters. The current study demonstrated that using DBM/AM composite can have more robust fusion than autologous bone at 6 weeks in an athymic rat spinal fusion model.
