Hidaka et al. now report that air pollutants can activate the aryl hydrocarbon receptor (AhR) in keratinocytes to induce the expression of type 2 cytokines and the
A recent study published in the Journal of American Medical Association Pediatrics observed a clinically significant association between exposure to mouse allergens and an increase in asthma symptoms as well as diminished lung function. Asthma is a pervasive health concern in the United States, however, asthma tends to disproportionately affect low-income groups and minorities residing

A recent study published in the journal Thorax has shown that living on a farm in childhood is associated with a lower risk of developing allergic diseases later as an adult, and strong lungs in women, compared to being brought up in an urban or rural area. There has been a sharp rise in the
A comprehensive review of scientific literature suggests a possible link between early introduction of allergenic foods and reduced likelihood of some allergies, although the evidence is not conclusive. Both popular and scientific literature have discussed the relationship between early introduction of certain foods to infant diets and the subsequent development of allergies or autoimmune problems.
A new study has found that using azithromycin as a treatment method among adults for asthma attacks has a rather clinically neutral benefit. Azithromycin is defined as an antibiotic used in the treatment of infections that are bacterial in nature. Asthma is a respiratory condition which greatly affects key organs such as the lungs, which
80% of patients who believed that they were allergic to penicillin received more effective therapy after penicillin skin allergy testing. Penicillin is a common antibiotic that is used to treat infections caused by bacteria. Up to 15% of patients admitted to hospitals report that they have an alleged allergy to penicillin. While penicillin allergies can
The number of nasal allergies is increasing over time, however, asthma symptoms among adults tend to remain stable. Although past research investigating the prevalence of asthma and allergies among adult populations is relatively scant, information that does exist tends to suggest two trends: first, that asthma symptoms tend to remain stable over time, and second,
According to a new study published in the Pediatrics journal, children who bite their nails or suck their thumbs are less likely to develop allergic sensitivities later in life. Those who have both habits have even a lower risk of developing allergies. Nail-biting and thumb-sucking are common habits among children, often seen as undesirable and
