Asthma (from the Greek άσθμα, ásthma, "panting") is the common chronic inflammatory disease of the airways characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm. Symptoms include wheezing, coughing, chest tightness, and shortness of breath. It is thought to be caused by a combination of genetic and environmental factors.
  • A boy plays in the mud on the bank of the Bago river in Bago March 20, 2012.
    New research suggests that childhood exposure to germs may help strengthen the immune system and protect children from developing allergies and asthma in later life.
  • Thalidomide victim, Tony Melendez, is shown in an undated file photo at age four while attending a therapy program at the University of California
    Previous studies linking use of prescription drugs for asthma, epilepsy, diabetes and depression during pregnancy to birth defects have compelled researchers to look further into the issue.
  • House dust mites (Dermatophagoides pteronyssinus).
    Scientists have discovered a new molecule capable of fighting common allergy symptoms that can cause asthma attacks, according to a study that will be published on Friday.
  • Mothers participate in a breastfeeding demonstration in Montreal January 19, 2011.
    Children breastfed as babies may have stronger lungs and a lowered risk of asthma compared to those who were fed infant formulas, according to new research.
  • Vehicles are seen during rush hour on the 405 freeway in Los Angeles, California October 3, 2007.
    Asthma cases that were caused or made worse by traffic pollution cost a total of $18 million a year on average in two California communities, according to a new study.

    New discoveries surrounding rheumatoid arthritis may help asthma sufferers as Queensland Medical Center found that two mutant genes found in around 58,000 sampled asthmatic patients are receptible to the same treatments that target Rheumatoid arthritis (RA) disease.
  • Molds that may produce mycotoxins should be considered hazardous to children. Exposure to moldy homes increases the likelihood of children developing asthma.

    Research introduces a new data connecting asthma in children to mothers who received high levels of exposure from vacuums, hair dryers and microwave ovens during pregnancy.
  • feeding a baby on only breast milk for up to six months after birth can reduce the risk of developing asthma-related symptoms in early childhood.
  • When children with asthma get the flu, they often land in the hospital gasping for air. Researchers at Children's Hospital Boston have found a previously unknown biological pathway explaining why influenza induces asthma attacks.
  • New tool to assess asthma-related anxiety
    When children or adolescents with asthma and their parents become overly anxious about the disorder, it may impair their ability to manage the asthma effectively. A new, effective tool to assess asthma-related anxiety is described in an article in Pediatric Allergy, Immunology, and Pulmonology, a peer-reviewed journal published by Mary Ann Liebert, Inc. The article is available free online.
  • Michael Croft, Ph.D., a researcher at the La Jolla Institute for Allergy & Immunology, has discovered a molecule's previously unknown role as a major trigger for airway remodeling, which impairs lung function, making the molecule a promising therapeutic target for chronic asthma, chronic obstructive pulmonary disease (COPD) and several other lung conditions. A scientific paper on Dr. Croft's finding was published online today in the prestigious journal, Nature Medicine.
