Researchers identified a molecular switch that turns on the allergic response in human, which cause such diseases as asthma, eczema, and food allergies.

A recent study by scientist at the University of Texas, M.D. Anderson Cancer Center, Houston, identified the molecular agent responsible for directing immune cells to develop the capability to produce allergic response. The molecular agent, called thymic stromal lymphopoietin (TSLP), is the culprit behind the development of allergic diseases such as asthma, atopic dermatitis (eczema), and food allergy in human, said the researchers; but how might this occur?

Outdoor allergens are usually harmless particles in your surrounding that can trigger an allergic reaction in people who are suffering from allergic asthma or other allergies. Outdoor allergens include grass, weed pollen, tree and mold spores.

Allergens are impurities present in the air that are foreign to the human body and can cause a specific hypersensitive reaction in a persons body. In breathing process when these substances are inhaled, they generate symptoms like coughing, tearing eyes, sneezing, headache, sore throat and itching in skin or any other part. If you have any allergic symptoms mentioned above, the first and foremost action that you need to take is to identify that what you are allergic to. This knowledge will help you eliminate the allergen to come in contact with you.

Heartburn or pyrosis is a painful or burning sensation in the esophagus, just below the breastbone caused by regurgitation of gastric acid. The pain often rises in the chest and may radiate to the neck, throat, or angle of the jaw. Heartburn is also identified as one of the causes of asthma and chronic cough.

Heartburn Diagnosis.

Physicians normally diagnose gastro esophageal reflux disease (GERD) based on symptoms alone. When the clinical presentation is uncertain, other tests can be performed to confirm the diagnosis or exclude other disorders. Confirmatory tests include:

asthma is the most common cause for admission to children's hospitals. Almost one in three children suffer asthma in Australia. When a child has a mucus discharge; inflammation of the tonsils (tonsillitis), ear or throat infection, the child is often routinely given a drug medicine such as a course of antibiotics to 'settle it down' or, 'dry it Up'. The medicine can often, in the beginning appear to succeed in reducing (the right word is 'suppressing') the symptoms.

Because the foreign matter of putrid mucus and puss settles down and stops flowing, it does not mean it has vanished! Far from it! It is physically and biologically impossible for it to just 'disappear'.
