Pyrexia of unknown origin (PUO) is a syndrome that has long tested the skills of physicians to achieve a diagnosis in affected patients. By definition, patients included in this syndrome will be more difficult to diagnose as they have already resisted classification during baseline investigations.
What does pyrexia of unknown origin mean?
Pyrexia of unknown origin (PUO) is defined as: Temperature greater than 38.3℃ on several occasions. Accompanied by more than 3 weeks of illness. Failure to reach a diagnosis after 1 week of investigation.
How is pyrexia of unknown origin treated?
Nonsteroidal anti-inflammatory drugs (NSAIDs) and antihistamines may also be used to treat FUOs that have no trace of underlying causes. In many people, these medications can help reduce the fever itself. People whose fevers are thought to have an immune-deficient origin may be treated with broad-spectrum antibiotics.
What causes a fever of unknown origin?
DON’T forget that infection is the main cause of FUO. Common infections include urinary tract infections, pneumonia, tuberculosis, endocarditis, osteomyelitis (infection of the bone), tick-borne diseases (e.g., Lyme disease), gonorrhea, syphilis, herpes, HIV, AIDS, and abdominal abscesses.How is fever of unknown origin diagnosed?
The syndrome of fever of unknown origin (FUO) was defined in 1961 by Petersdorf and Beeson as the following: (1) a temperature greater than 38.3°C (101°F) on several occasions, (2) more than 3 weeks’ duration of illness, and (3) failure to reach a diagnosis despite one week of inpatient investigation.
What is the use of pyrexia?
Pyrexia, also known as fever, is an increase in the body temperature of an individual beyond the normal range. This increase in temperature is usually considered dangerous, but it is a natural defensive mechanism of the body to fight against infections.
What is swinging pyrexia?
Hectic fevers, because of wide swings in temperature, are often associated with chills and sweats. This pattern is thought to be very suggestive of an abscess or pyogenic infection such as pyelonephritis and ascending cholangitis, but may also be seen with tuberculosis, hypernephromas, lymphomas, and drug reactions.
What are the symptoms of pyrexia?

How do you get hyperthermia?
Hyperthermia often occurs during physical exertion or exercise in a warm or humid environment. During exercise, blood pressure rises to deliver more oxygen to working tissues, increasing body temperature and the amount of work the body must do to maintain a stable temperature.
Does pain cause pyrexia?
Fever and headache pain Other illnesses and inflammation can also trigger a fever. You might have a fever if your body temperature is higher than 98.6°F (37°C).
What is persistent pyrexia?
Persistent (chronic) fevers are typically defined as fevers lasting more than 10 to 14 days. A fever can mean a lot of different things, but most low-grade and mild fevers are nothing to worry about. Most often, an increase in body temperature is a normal response to an infection, like a cold or the flu.

What's the difference between pyrexia and hyperthermia?

Is pyrexia the same as fever?
Fever, also referred to as pyrexia, is defined as having a temperature above the normal range due to an increase in the body’s temperature set point.
