Pneumonia is a respiratory condition in which there is inflammation of the lung. Community-acquired pneumonia refers to pneumonia in people who have not recently been in the hospital or another health care facility (nursing home, rehabilitation fa...

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.

A pleural effusion is an accumulation of fluid between the layers of tissue that line the lungs and chest cavity.
|
|
Pleural effusion occurs when too much fluid collects in the pleural space (the space between the two layers of the pleura). It is commonly known as "water on the lungs." It is characterized by shortness of breath , chest pain , gastric discomfort ...

Disseminated intravascular coagulation (DIC) is a serious disorder in which the proteins that control blood clotting become abnormally active.

This condition is a bleeding disorder resulting from the widespread overstimulation of the body's clotting and anticlotting mechanisms in response to illness, stress, or both. Disseminated intravascular coagulation (DIC) occurs mainly within the c...
