Print This Post, introduction, asthma, characterized by reversible airflow obstruction, has afflicted people since ancient times. Described by Galen in the second century as epilepsy of the lungs, an array of famous people have suffered from asthmafrom Ludwig von Beethoven to allergy Billy Joel, from the ancient Roman philosopher and politician, Seneca to President Bill Clinton, and from baseball pitcher, Jim Catfish. In the US, its prevalence has increased dramatically in the last decade and now affects more than 25 million.3 Asthma is the most common chronic disease among children under 5 years old, and is the leading cause of morbidity reflected in absence from daycare, emergency.
While the number of hospitalizations and emergency room visits attributed to asthma have stabilized in recent years, the death toll from asthma remains significant.
Efforts to simply and refine the treatment of patients with asthma have continued.
Global and national initiatives focusing on the treatment and prevention of asthma have been developed over the last twenty years, with periodic updates that reflect not only the increased appreciation of the complex pathophysiology of the disease, but also improvement in the therapeutic agents that. People who have asthma have more than 497,000 hospitalizations annually.8. Thus, the need to improve the recognition of asthma and to apply the latest evidence-based guidelines continues to be substantial.
Recently, three major international asthma guidelines Global Initiative for Asthma gina, 2011, the British Thoracic Society BTS, 2012, and the Canadian Thoracic Society CTS, 2012) have been updated and their recommendations reflect a growing consensus about the importance of definition asthma and assessment of asthma control.4-10.
While focusing on diagnosis and treatment, they also address the emerging science such as the use of biomarkers and genetic testing that may soon be appropriate for clinical practice.4-10. According to the 2012 CTS guideline, the definition of asthma is unchanged from its 2010 iteration: Asthma is an inflammatory disorder of the airways characterized by paroxysmal or persistent symptoms such as dyspnea, wheezing, coughing and sputum production associated with airflow limitation and airway hyperresponsiveness. 10, most guidelines address young children (preschoolers or 5 years) separately from older children and adults for a variety of reasons.
For example, while wheezing is nearly ubiquitous in patients with asthma, not all young children who wheeze have asthma. Consequently, other possible causes of wheezing, shortness of breath and the other hallmarks of asthma must be ruled out.6,7 An additional challenge in diagnosing asthma in young children is the fact that routine, accurate assessment of airflow limitation and inflammation is often not possible, particularly.
A allergy trial of short-acting bronchodilator and inhaled corticosteroid along with a compelling clinical history are helpful in suggesting this diagnosis in very young children.4,5.
Diagnosis of asthma in older children and adults is somewhat less challenging because pulmonary function studies are more reliable diagnostic tools. Indeed, the principal difference between the assessment of control in young children and assessment of adults is the recommendation to use. . Both the 2007 National Asthma Education and Prevention Program, Expert Panel Report 3 and the 2011 gina update, recommend office spirometry peak expiratory flow (PEF) and/or forced expiratory volume in one second (FEV1)as the preferred tool for diagnosis and treatment in children over five and.
