Asthma: What You Should Know

Bronchial Asthma In Children. Diagnosis And The Principles Of Treatment

Bronchial asthma is an allergic disease, which is based on chronic inflammation in the respiratory tract and bronchi’s hyperactivity to the impact of various incentives. The disease is characterized by recurrent episodes of bronchial obstruction, partially or completely reversible, accompanied by fits of coughing, wheezing and by tightness in chest.

The increase in prevalence of asthma in all age groups is considered to be due to the following factors:
•    The impact of air pollutants inside homes, due to the peculiarities of modern building materials and recycling of air (nitrogen dioxide, cigarette smoke, etc.) and an increase of different allergens (dust mites, cockroaches, fungi, and animal hair).
•    The incidence of acute respiratory viral infection in early childhood.
•    The syndrome of respiratory disorders, bronchopulmonary dysplasia, etc.
•    Smoking in the family; smoking while pregnancy or nursing pregnant affects the lungs of the protembryo or infant.

The development of bronchial asthma in children is due to genetic predisposition and the environmental factors. There are three main groups of factors that contribute to the development of the disease:
•    Predisposing factors (genetic burden to allergic diseases, atopy, and bronchial hyperactivity).
•    Etiological agents/sensitizing factors (allergens, viral infections, drugs).
•    Aggravation factors (or so-called triggers) that promote inflammation in bronchi and/or provoke the development of acute bronchoconstriction (allergens, viral and bacterial infections, cold air, cigarette smoke, emotional stress, physical stress, weather conditions, etc.). continue reading »

Different Allergic Reactions And Their Treatment

Any physical irritation meets its response of the stimulated object. Similar occurs in the human organism. But this respond to the trigger is called an allergic reaction of the body to the physical action of the “invader”. The body perceives the “different” substance, which is also named an antigen. It is normal that the immune system protects the organism from hazardous bacteria and toxins by mucifying process. This overreaction to the substances detrimental to health is named hypersensitivity reaction.
Absolutely different substances or conditions can turn out to be allergen for the human organism. Thus, for instance, such things as dust, pollen, various plants or foodstuffs, definite medicines, insect venoms, viruses and bacteria may be typical allergens. These reactions can have various forms and places of its presentation. Consequently, the sufferer may complain of itchy eyes, skin rash. The latter can be presented either in one spot or all over the body. The reaction to the exogenous irritant may have more than one symptom simultaneously. continue reading »
