Childhood Asthma
The powerful of development made in medicine in the 20th and 21st century even though there are still many terrifying diseases and illnesses yet to be conquered. One of the most mysterious of these is asthma and the statistics for asthma in the US are alarming. The numbers show rates of asthma among Americans has been increasing for the past few years and will likely continue to raise according to recent asthma statistics. (CDC, 2011, p. 3) When people have heard about asthma, they know that it’s an illness which is relative with respiratory organs. They may not know exactly what it is, how and why their children have that disease. Understanding about asthma is a good way to protect and treatments children. Asthma is a complex illness and can be defined in many ways. Basically asthma is a chronic disease of the airway of the lungs. Unfortunately, asthma never goes away, but the right treatment can help keep it under control. There are three overall contributing factors leading to the development of asthma. First, there is an airway obstruction in which the airways of the lungs or bronchial tubes are narrowed. Airway obstruction is a common symptom of asthma that may be caused by environmental factors, allergies or stress. Because air can no longer flow smoothly in these passageways, obstruction occurs. However, because these tubes which allow air to pass through can dilate, and open, this type of obstruction is considered reversible. In this way, asthma can be distinguished from other types of bronchial illnesses like bronchitis and emphysema, in which the obstruction is irreversible. Often the bronchial tubes or lungs will narrow in such a way as to resemble a muscle cramp in that there is a tightening of the muscle, constricting air flow (Adams, F.V, 1998, p. 9). The air travels through the nose or mouth to a tube which is called trachea and get into a series of smaller tubes called bronchi. Then, the air is broken down into smaller tubes called the bronchioles. Asthma has a main effect on the bronchi and bronchioles (Asthma and Allergy Foundation of American, 2005, p. 2). Secondly, inflammation is considered an important leading cause and common symptom of asthma. Bronchial tubes in an asthma patient typically are red and swollen. This is threatening and becomes the focus of asthma therapy. According to Francis and M.D, a bronchoscope is a device a physician inserts into the bronchial tubes to obtain samples of the lining and mucous secretions. Looking at these samples of cells under a microscope will help the physician to determine if there are asthma mediator cells which have been released during episodes of high inflammation or an actual asthma attack (Adams, F.V, 1998, p. 9). Finally, a third defining feature of asthma is hyperirritability. This is an action of the bronchial tubes where they tend to "overreact" and narrow to stimuli. Often patients who are susceptible to this feature have rapid and severe asthma attacks in reaction to animal dander, dust, and fumes. This is considered a hyperactive reaction of the lungs and bronchial tubes to external factors and may need further testing in a doctor's office to rule out other factors (Adams, F.V, 1998, p. 9, 10). Asthma is a big seriously issue nowadays. Also, it is one of the highest ranked causes of pediatric hospitalizations in the...
