African Americans also have a high incidence of this disease. Irish Americans and Hawaiians also have a high incidence of asthma. The lowest incidence is found in the Mexican population. Although the incidence of pediatric asthma is higher in males than in females, the occurrence of this disease is much higher in adult females, who are twice as likely to die of this disease as males. Moreover, the incidence of asthma is higher in lower socioeconomic groups who reside in urban centers.
There are two primary forms of this disease: acute and chronic. The acute form of the disease is characterized by the occurrence of in worsening symptoms and unstable bronchial function. The chronic form of the disease is a stable, non-progressing condition (Adam 10). Many patients with asthma vary over time between the two disease states. Asthma can be distinguished from several other major forms of lung disease by means of differential diagnosis. Unlike emphysema which affects the structure and function of the alveoli, the primary site of gaseous exchange in the lung, asthma affects the airways or conductance passage that transport air between the lung tissue and the external opening of the body. Likewise, COPD is an irreversible deterioration of the primary lung tissue; in contrast at the inflammatory manifestations of asthma are reversible (Adam 20-23).
Asthma is a chronic pulmonary disorder characterized by inflammation of the major airways of the lungs and has a complex etiology. The recurring inflammatory episodes result in hyper-responsiveness of airway vessels that causes tissue swelling with many physiological consequences (Adam 44). These episodes cause symptoms of wheezing, tightness of the chest, coughing and restricted airflow that result in ...Download file to see next pagesRead More

Asthma

...? Asthma - Asthma General Background What is Asthma Asthma is defined as a chronic respiratory disease characterised by episodes of acute airflow obstruction, increased mucous production, bronchial hypersensitivity and airway inflammation caused by a cascade of conditions and interactions. Each of the mentioned interactions is influenced to a great extent by the internal physiologic environment and external factors. The wheezing and shortness of breath experienced by an individual during an asthmatic attack are a result of physiologic interactions. The attacks are triggered by airway irritants such as cigarette smoke, allergens, and environmental pollutants. (Clark 2011, p.15-16). History of Asthma: The history of asthma is as old... as...

Asthma

...?Asthma Introduction Asthma is known to be a chronic disease, encompassing varied and frequent symptoms resulting in impediment of reversible airflowdue to inflammation of inner walls of airways, generating sensitivity to irritations and thereby augments susceptibility to allergies. Swelling results in narrowing of air passage to and from the lungs causing bronchospasm, associated with puffing, cough, stiffness in chest and shortness of breath. Asthma is a result of deregulated immunological condition in respiratory mucosa; the condition is gaining prevalence across the globe and shows drastic augmentation since 1970s. It is reported that in 2009, 300 million people were influenced...

...Asthma Introduction Asthma is one of the major diseases which affect our lungs and our breathing passages. According to the National Heart Lung andBlood Institute (“Lung Diseases”) it is a disease where narrow airways become inflamed and later manifests with recurring periods of wheezing, chest tightness, shortness of breath and coughing. It manifests at almost any age but often starts as early as the childhood years. About 22 million people in the United States, with about 6 million of them being children, are afflicted with this disease. In fact it is the most common childhood illness in the United States (Schiffman, et.al., p. 1). This disease often manifests through various patient-specific triggers, the most common... of which...

...Introduction Asthma, affects a total of 300 million people worldwide. The National Asthma Council of Australia defines asthma as a reversible narrowing of the airways of the lungs and symptoms include wheezing, coughing (particularly at night), chest tightness, difficulty breathing and shortness of breath (www.nationalasthma.org.au). Asthma is a treatable disease, however currently there is no cure. Asthma in Austrailia is among the highest in the world. It is estimated that 1 out 10 Australians, which is equivalent to over 2 million people in Australia live with Asthma. According to Health Insight 10-15% of all children and 10-12% of...

...Asthma al Affiliation Background: Asthma is an inflammatory disease of the airways that causes narrowing of the airways causing to obstruction of airflow leading to symptoms such as wheezing, dyspnoea, chest tightness and coughing. Asthma affects the quality of life of the patients and is and is an economic burden to the families due to medical expenses and hospitalisations. Asthma is prevalent in westernised environments as compared to rural areas. Aims and objectives: To identify ways in which asthma can be caused, its pathophysiology, prognosis, epidemiology, signs and symptoms, diagnosis, treatment, prevention and management. Proper management of the...

...Use of Inhaled Corticosteroids The use of Inhaled Corticosteroids Corticosteroids help in a wide range of physiological processes and most importantly in this context to regulate inflammation (Brandon, 1962). Elements in treatment of asthma are corticosteroids and other anti-inflammatory drugs. These drugs help to reduce inflammation, swelling and the production of mucus in the airways of an asthmatic person. This prevents asthmatic triggers and allows people with asthma to have better control over their condition. Long-term asthma control medications are taken on a regular basis to help control chronic symptoms and prevent asthma attacks. They include; inhaled...

Asthma

...Asthma Definition and symptoms Asthma is a disease that affects people across all age groups and in most cases typically begins in childhood. Asthma is primarily characterized by periodic breathlessness accompanied by wheezing. The intensity of the attack may vary from one person to another and also have varying occurrence by the hour and days in an individual. The major cause of the disease is attributed to the inflammation of the bronchial passages and this in turn affects the sensitive nerve terminals resulting in their irritability and functional disruption. During an attack the bronchial linings become inflamed which causes narrowing of the air passage and subsequently reduction in air flow into and out of the lungs (Asthma... )....
