orchard workers in north china are highly exposed to orchard pollens, especially peach and other rosaceae family pollens during pollination season. the aim of this study was to investigate whether occupational allergy to peach tree pollen as a member of rosaceae family is ige-mediated and to evaluate the cross-reactivity among rosaceae family pollens. allergen skin test and conjunctival challen...

Seasonal pollen allergies affect approximately 1 in 5 school age children. Clinical research has established that these allergies result in large and consistent decrements in cognitive functioning, problem solving ability and speed, focus and energy. However, compared to air pollution, the impact of pollen and seasonal allergies on achievement in schools has received less attention from economi...

Asthma and allergic diseases cases have risen in recent decades. Plant pollen is considered as the main aeroallergen causing allergic reactions. According to available data, urban residents experience more respiratory allergies than rural residents mainly due to the interaction between chemical air pollutants and pollen grains. This interaction can occur through several mechanisms; chemical pol...

This manuscript deals with an important and interesting topic: the simulation of regional-scale pollen dispersal in a highly populated region of Southern California. Pollen allergies are among the most common respiratory allergies, and they are likely to become an even greater concern as the incidence of allergies rises. Studies such as this one could potentially be used to guide public health ...

4 MA in diagnosing pollen allergies Improving the diagnostic work-up of pollen allergic patients For successful specific immunotherapy (SIT) treatment of pollen allergies the patient should be treated with an appropriate extract containing the actual symptom-triggering proteins in sufficient quantities. Molecular allergology (MA) helps to pin-point the actual allergenic molecule(s) responsible ...

BACKGROUND Birch pollen allergies are frequently associated with adverse reactions to various fruits, nuts, or vegetables, described as pollen-food syndrome (PFS) and caused by cross-reactive IgE antibodies primarily directed against Bet v 1. Specific immunotherapy (SIT) represents an effective treatment for inhalant allergies; however, successful birch pollen SIT does not correlate well with t...

BACKGROUND Human papillomavirus is the acknowledged cause of cervical cancer. We hypothesized that allergies, characterized by hyperimmune reaction to common allergens and which have been associated with various cancers, may be related to cervical cancer, and that genetic variation in cytokine genes related to allergies might impact cervical cancer risk. METHODS We investigated the risk of in...

Pollen respiratory allergies have been increasing in prevalence over the last two decades, partly as the result of the impact of climate change. For many allergenic trees, grass and weed species, increased pollen production and prolonged pollination period result in long-term increased abundance of pollen allergens in the atmosphere; earlier shifts of airborne pollen grains and prolonged exposu...

BACKGROUND A recent study carried out in North of Milan, an area that was recently colonized both by birch and ragweed pollen, showed that subjects developing allergies to these "new" allergens were much older than those becoming allergic to "traditional" airborne allergens, which suggests that predisposition to develop respiratory allergies is probably allergen-specific, persists throughout li...
