BACKGROUND The aim of this study was to evaluate the relation between colonization and vaccination status with pneumococcal conjugate vaccine (PCV) in older children and adolescents living in an area characterized by relatively limited vaccination coverage. METHODS Oropharyngeal swabs were obtained from 2076 randomly selected healthy school-age children(More)
Streptococcus pneumoniae and Staphylococcus aureus are common commensals of the upper respiratory tract in children and adolescents. Understanding the relationship between these two pathogens, including their potential for mutual interference, is needed to evaluate the epidemiology of the diseases they cause, the factors that condition acquisition and(More)
This study evaluated the immunogenicity, safety and tolerability of a single 0.5 mL dose of the seasonal virosomal subunit influenza vaccine (Inflexal V, Crucell, Switzerland) in 205 healthy, unprimed children aged at least 6 to <36 months, evaluated at four weeks post-vaccination and seven months from baseline. Of the enrolled children, 102 received one(More)
The intracellular mechanisms driving postmitotic development of cortical γ-aminobutyric acid (GABA)ergic interneurons are poorly understood. We have addressed the function of Rac GTPases in cortical and hippocampal interneuron development. Developing neurons express both Rac1 and Rac3. Previous work has shown that Rac1 ablation does not affect the(More)
In order to compare the immunogenicity and safety of different doses of trivalent influenza vaccine (TIV) administered intradermallly (ID) with those evoked by a full dose of intramuscular (IM) virosomal-adjuvanted influenza vaccine (VA-TIV), 112 previously primed healthy children aged ≥ 3 years were randomised to receive 9 μg or 15 μg of each strain of(More)
Every year for the last few decades, the health authorities of most countries throughout the world have issued specific recommendations for the prevention and treatment of pediatric influenza, including recommendations concerning the use of vaccines. However, different evaluations of the importance of the disease and the efficacy of influenza vaccination(More)
Annual vaccination is the most effective means of preventing and controlling influenza epidemics, and the traditional trivalent inactivated vaccine (TIV) is by far the most widely used. Unfortunately, it has a number of limitations, the most important of which is its poor immunogenicity in younger children and the elderly, the populations at greatest risk(More)
The purpose of this investigation was to evaluate the effectiveness of posterior pharyngeal and nasopharyngeal swabs in identifying and quantifying meningococcal carriage. Two swab samples were obtained from 564 healthy adolescents aged 15–19 years, the first taken from the posterior pharyngeal wall through the mouth and the second through the nose.(More)
Nasopharyngeal swabs obtained from 78 pediatric patients with cystic fibrosis (CF), including 47 with acute pulmonary exacerbation and 31 in a stable clinical condition, were evaluated for 17 respiratory viruses. Human rhinovirus (HRV) was the most frequently detected virus in patients with pulmonary exacerbation and in those who were clinically stable(More)
BACKGROUND Air pollution has many negative health effects on the general population, especially children, subjects with underlying chronic disease and the elderly. The aims of this study were to evaluate the effects of traffic-related pollution on the exacerbation of asthma and development of respiratory infections in Italian children suffering from asthma(More)
