Respiratory viral infections profoundly influence the disease activity of wheezing illnesses and asthma in early childhood. Viral bronchiolitis shares many features with asthma and a subset of children develop recurrent wheezing after their initial illness. Recently mechanisms for virus-induced exacerbations of childhood asthma are beginning to be focused on and defined. Viruses cause systemic ...

To investigate if air pollution and greenness exposure from birth till adulthood affects adult asthma, rhinitis lung function. Methods: We analysed data 3428 participants (mean age 28) in the RHINESSA study Norway Sweden. Individual mean annual residential exposures to nitrogen dioxide (NO2), particulate matter (PM10 PM2.5), black carbon (BC), ozone (O3) (normalized difference vegetation index ...

Objectives: There is inconsistent evidence on the relationship between pesticide exposure and childhood respiratory outcomes in non-agricultural settings. This study investigated association organophosphate (OP) asthma-related children residing four informal settlements. Methods: The was a longitudinal of 590 schoolchildren, with 12 months follow-up period. A standardised questionnaire adopted ...

BACKGROUND The presence of visible mold in households is associated with asthma. However, the role of "classroom fungus" in the development of childhood asthma, as well as the fungal species that may lead to asthma, remains controversial. This nationwide school survey was conducted to investigate the correlation between fungal spores in classrooms and asthma in schoolchildren. METHODS From Ap...

Nearly one in every thirteen children has asthma, making it the most common chronic condition in childhood. For a variety of biological and environmental reasons, the prevalence of childhood asthma has risen dramatically in the past 20 years, with disproportionate effects on low-income populations, minorities, and children living in inner cities. Much of the morbidity associated with childhood ...

Background: It has been suggested that Helicobacter pylori infection might reduce the risk of atopic conditions, such as asthma, in childhood. This risk reduction could relate to the “hygiene hypothesis” which proposes an association between childhood exposure to microbes and risk of atopy. Objectives: To examine the association between Hp infection and childhood acquired asthma in Sardinia. Pa...

Introduction: Allergic rhinitis and asthma can be related to occupation. The present study aimed to investigate the correlation between asthma or allergic rhinitis and employment in the palm tree gardens of Jahrom, Iran.   Materials and Methods: This was a cross-sectional study including 50 palm tree garden workers and a control group of 50 office employees. Data collection included demographic...

The burden of asthma in childhood is considerable worldwide, although some populations are much more affected than others. Many attempts have been made by different investigators to identify the factors that could predict asthma development or persistence in childhood. In this review, the relation between atopic sensitization as an indicator of allergy and asthma in childhood will be discussed....

Adverse childhood experiences such as abuse and neglect are associated with subsequent immune dysregulation. Some studies show an association between adverse childhood experiences and asthma onset, although significant disparity in results exists in the published literature. We aimed to review available studies employing a prospective design that investigates associations between adverse childh...

Extensive literature exists on potential risk factors for childhood asthma. To the authors’ knowledge, no investigators have yet attempted to disentangle the effects of those determinants within a single study setting. The authors aimed to evaluate the independent effects of 47 potential determinants (from the prenatal, perinatal, and childhood periods) of asthma development in children within ...
