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

|
|
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...

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.

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. In the United States, pneumonia is the sixth most common disease leadi...

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.

The following Clinical Topic Tour provides an overview of pneumococcal pneumonia and was adapted by materials published by the National Institute of Allergy and Infectious Diseases and the CDC.

Pneumococcal pneumonia is a common but serious infection and inflammation of the lungs. It is caused by the bacterium Streptococcus pneumoniae .

|
Pneumocystis pneumonia is a lung infection that occurs primarily in people with weakened immune systems—especially people who are HIV-positive. The disease agent is an organism whose biological classification is still uncertain. Pneumocystis carin...

Chlamydial pneumonia refers to one of several types of pneumonia that can be caused by various types of the bacteria known as Chlamydia .

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 . Lobar pneumonia affects one section, or lobe, o...

Eosinophilic pneumonia is a group of diseases in which there is an above normal number of eosinophils in the lungs and blood.

Pneumonia is an infection of the lungs that can be caused by nearly any class of organism known to cause human infections, including bacteria, viruses, fungi, and parasites. It results in an inflammatory response within the small air spaces of the...

Emphysema is a chronic respiratory disease where there is over-inflation of the air sacs (alveoli) in the lungs, causing a decrease in lung function, and often, breathlessness.
|
|
Emphysema is a lung disease that, along with chronic bronchitis, represents a type of chronic obstructive pulmonary disease (COPD). Medical scientists have defined emphysema as "a condition of the lung characterized by abnormal, permanent enlargem...
|
|
Emphysema is a chronic respiratory disease in which overinflation of the alveoli or air sacs causes a decrease in respiratory function and often dyspnea.
|
|
|
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.
|
|
Pulmonary hypertension is a rare lung disorder characterized by increased pressure in the pulmonary artery. The pulmonary artery carries oxygen-poor blood from the lower chamber on the right side of the heart (right ventricle) to the lungs where i...

Cor pulmonale is failure of the right side of the heart brought on by long-term high blood pressure in the pulmonary arteries and right ventricle of the heart.
|
|
Cor pulmonale is an increase in bulk of the right ventricle of the heart, generally caused by chronic diseases or malfunction of the lungs. This condition can lead to heart failure .

Cyanosis is a physical sign causing bluish discoloration of the skin and mucous membranes. Cyanosis is caused by a lack of oxygen in the blood. Cyanosis is associated with cold temperatures, heart failure , lung diseases, and smothering. It is see...

Painless swelling of the feet and ankles is a common problem, particularly among older people. Abnormal buildup of fluid in the ankles, feet, and legs is called peripheral edema.
|
|
|
Edema is a condition of abnormally large fluid volume in the circulatory system or in tissues between the body's cells (interstitial spaces).
