Pneumonia can develop from either acute or chronic bronchitis. If you have chronic bronchitis, you are more likely to develop recurrent respiratory infections.

When treated, acute bronchitis normally resolves in one to two weeks without complications, although a cough may continue for several more weeks. The progression of chronic bronchitis, on the other hand, may be slowed, but an initial improvement i...

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.

Pneumonia is an infection of the lung, and can be caused by nearly any class of organism known to cause human infections. These include bacteria, viruses, fungi, and parasites.

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.

Emphysema is a progressive, incurable chronic lung condition. The air sacs(alveoli) are destroyed and oxygen uptake is restricted due to the loss of elasticity of lung tissue.As of 1998 there were an estimated two million people suffering from emp...
