Most children recover uneventfully from bronchiolitis, although some studies have suggested that children who have had bronchiolitis may be at higher risk for reactive airway disease throughout the remainder of their lives.

The most common mechanism by which the lung is inoculated with pathogenic organisms is through microaspiration of oropharyngeal contents, a process that occurs in otherwise healthy individuals during sleep ( Chapter 82 ). Colonization of the oral pharynx with pathogenic organisms, such as Streptococcus pneumoniae ( Chapter 303 ), can thereby lead to delivery of sufficient quantities of organisms to infect the lung.

Introduction Pneumonia has been recognized as a disease entity since remote times, with definitions of the condition traceable in ancient Greek, Roman, and Arabic writings. Definitive recognition of the etiologic role of microorganisms in pneumonia, and the identification of Streptococcus pneumoniae as the most common causative agent was only achieved roughly 120 years ago.
|
|
The actual incidence of pneumonia in ambulatory patients is difficult to estimate because the etiologic agent is rarely identified except in clinical trials, and CAP is not currently considered a reportable disease. Each year in the United States there are 2 to 3 million cases of CAP.

Pneumonia is a serious infection of the lung that impairs breathing. Small air sacs in the lung(alveoli) become filled with pus, mucus or other fluid, and cannot supply oxygen to circulating blood.

Asthma is an inflammatory disorder of the airways, which causes attacks of wheezing, shortness of breath, chest tightness, and coughing.
|
|
|
Asthma is a chronic inflammatory disease of the airways in the lungs. This inflammation periodically causes the airways to narrow, producing wheezing and breath-lessness sometimes to the point where the patient gasps for air.
|
|
|
Asthma is a chronic inflammatory disease of the respiratory system that causes breathing difficulty. Asthma comes from the Greek word for panting.
|
|
Asthma is a disease of the respiratory system that causes breathing difficulty. Asthma is typically expressed by repeated but reversible episodes of constriction and inflammation of the airways and lungs.
|
|
|
Today asthma is viewed as a chronic(long-lasting) inflammatory disease of the airways. In those susceptible to asthma, this inflammation causes the airways to narrow periodically.

Asthma is a chronic inflammatory disease of the airways in which periods of relatively free breathing are punctuated by episodes in which breathing becomes difficult. During an attack, inflammation causes the airways to fill with mucus secretions ...

Asthma is a common chronic lung disease characterized by a narrowing of the airways, resulting in obstruction of the flow of air and difficulty in breathing. The airflow obstruction is partially or completely reversible in most patients.

Respiratory failure occurs when the lungs'' ability to either add oxygen to the bloodstream or remove carbon dioxide from it is impaired. Respiratory failure can have any one of several causes, such as lung disease or infection, electrolyte imbalan...
