The prognosis for recovery from trichinosis is generally good. Most people with the disease are unaware that they have even been infected. It is estimated that between 150,000 and 300,00 people in the United States become infected yearly, so that ...

Encephalitis is irritation and swelling (inflammation) of the brain, usually due to infections. See also: Meningitis
|
|
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. When both the...

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 i...

An inflammatory disease of the brain caused by a virus that either has invaded the brain, or a virus appearing elsewhere in the body that has caused a sensitivity reaction in the brain. Encephalitis infects the brain tissue itself and has serious ...

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.

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

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...

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...

Heart failure, also called congestive heart failure, is a condition in which the heart can no longer pump enough blood to the rest of the body.
|
|
Heart failure is a condition in which the heart has lost the ability to pump enough blood to the body's tissues. With too little blood being delivered, the organs and other tissues do not receive enough oxygen and nutrients to function properly.
|
|
"Heart failure" is a broad term—often used inter-changeably with "congestive heart failure" (CHF)—to describe the heart's inability to consistently pump enough blood to the body's organs and tissues. Heart failure occurs either from a structural o...

Myocarditis is inflammation of the heart muscle. See also: Pediatric myocarditis
|
|
Myocarditis is an inflammatory disease of the heart muscle (myocardium) that can result from a variety of causes. While most cases are produced by a viral infection, an inflammation of the heart muscle may also be instigated by toxins, drugs, and ...

An arrhythmia is a disorder of the heart rate (pulse) or heart rhythm, such as beating too fast (tachycardia), too slow (bradycardia), or irregularly.
|
|
An arrhythmia is an abnormality in the heart's rhythm, or heartbeat pattern. The heartbeat can be too slow, too fast, have extra beats, skip a beat, or otherwise beat irregularly.
