While the elderly and the chronically ill are at greater risk for secondary infection and other complications, they can also recover completely. While most people fully recover from an influenza infection, the flu should not be viewed with complac...

Otitis is a general term for infection or inflammation of the ear.Otitis can affect the inner or outer parts of the ear. The condition is classified according to whether it occurs suddenly and for a short time(acute) or repeatedly over a long peri...

Bronchitis is an inflammation of the main air passages to the lungs. Bronchitis may be short-lived(acute) or chronic, meaning that it lasts a long time and often recurs.See also: Chronic obstructive pulmonary disease(COPD).Acute bronchitis general...

|
The term"bronchitis" refers to the inflammation of medium-sized and large airways in the lung(bronchi). Bronchitis is distinguished from bronchiolitis(inflammation of small airways that lack cartilage and mucus-secreting glands in their walls) and...
|
 |
Bronchitis is an inflammation of the air passages between the nose and the lungs, including the windpipe, or trachea, and the larger air tubes called bronchi that bring air into the lungs from the trachea. When bronchitis is mild and brief in dura...

A lower respiratory inflammation affecting the windpipe(trachea) and bronchial tubes.Bronchitis can be caused by viruses, bacteria, or allergies, and it occurs in both acute and chronic forms, the former usually caused by a virus and the latter by...

Pneumonia is an infection of the lungs. Many different organisms can cause it, including bacteria, viruses, and fungi.Pneumonia is a common illness that affects millions of people each year in the United States.Bacterial pneumonias tend to be the ...

|
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.
|
|
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.
|
 |
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.
|
|
Eosinophilic pneumonia is a group of diseases in which there is an above normal number of eosinophils in the lungs and blood.Eosinophilia is an increase in the number of eosinophils. Eosinophilic pneumonia is characterized by a large number of eos...

|
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 an infection of the lungs. The air sacs(alveoli) and/or the tissues of the lungs become swollen, a...

 |
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...

One of the most common pulmonary complications affecting cancer patients, pneumonia is a potentially life-threatening inflammation of one or both lungs.Serious side effects in cancer patients most often occur in the lungs and may indicate that the...

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

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.The gram-positive, spherical bacteria, Streptococcus pneumoniae, is the cause of many human diseases, in...

|
Encephalitis is irritation and swelling(inflammation) of the brain, usually due to infections.Encephalitis is most often caused by a viral infection. Many types of viruses may cause it.
|
|
Although the word meningitis suggests an inflammation of the meninges only, there is always some involvement of the most superficial parts of the brain that are contiguous to the meninges. Often there are also alterations in the flow of cerebrospinal fluid (CSF).
|
|
Encephalitis is an inflammation of the brain, usually caused by a direct viral infection or a hypersensitivity reaction to a virus or foreign protein. Brain inflammation caused by a bacterial infection is sometimes called cerebritis.
|
 |
Encephalitis is an acute inflammatory process that affects brain tissue and is almost always accompanied by inflammation of the adjacent meninges(tissues lining the brain). There are many types of encephalitis, most of which are caused by viral in...
|
|
Encephalitis infects the brain tissue itself and has serious consequences.Among the many forms of encephalitis are those that occur seasonally, those that affect animals, and a form that is carried by a mosquito. Viruses that have been directly im...
