There is little evidence on the incidence and characteristics of local allergic rhinitis (LAR) in children. Most studies have included subjects with perennial only, results are based investigation no more than three allergens per study. Our aim was to determine proportion children LAR amongst chronic, difficult-to-treat, or seasonal, but sensitization aeroallergens, other alternative diagnosis.We performed multiple nasal provocation tests (M-NPTs) four locally relevant aeroallergens (Phleum...

From early life, respiratory viruses are implicated in the development, exacerbation and persistence of conditions such as asthma. Complex dynamics between microbial communities host immune responses shape maturation homeostasis, influencing health outcomes. We evaluated hypothesis that virome is linked to systemic responses, using peripheral blood nasopharyngeal swab samples from preschool-age children PreDicta cohort.Peripheral mononuclear cells 51 (32 asthmatics 19 healthy controls)...

Nasal irrigations (NI) are increasingly used as an over-the-counter adjunctive treatment for allergic rhinitis (AR), but clinical studies on their effectiveness limited.An open-label, controlled, non-randomized, real-life study was conducted to evaluate the of NI with a new hypertonic solution add-on AR. Children and adolescents AR were prescribed symptomatic treatment. The active group also received additional sea-water supplemented algae extracts. primary endpoint symptom control, assessed...

Background Hip fractures are an increasingly common injury among older people who usually experience significantly worse mobility, independence in function, health, quality of life, and high rates institutionalization. Studies have shown that only 40-60% participants recover their pre-fracture level mobility ability to perform instrumental activities daily living, while for those independent self-care prior the fracture, 20-60% still require assistance various tasks one or two years after...

Fractional exhaled nitric oxide (FeNO) is a non-invasive marker for eosinophilic airway inflammation and has been used monitoring asthma. Here, we assess the characteristics of FeNO from preschool to school age, in parallel with asthma activity. A total 167 asthmatic children 66 healthy, age-matched controls were included 2-year prospective PreDicta study evaluating wheeze/asthma persistence preschool-aged children. Information on asthma/rhinitis activity, infections atopy was recorded at...
