Study Notes
Body Temperature and Fever
- The normal range for body temperature is not explicitly stated, but a temperature above 37.5°C is considered abnormal.
Fever Classification
- Pyrexia is an abnormally high body temperature, ranging from 37.5°C to 38°C.
- Hyperpyrexia refers to an extremely high body temperature, above 41.5°C.
Pyrexia of Unknown Origin (PUO)
- According to Petersdorf and Beeson, PUO is defined as an elevation of body temperature above 38.3°C for more than three weeks with no definite diagnosis made after initial investigations.
Physiological Causes of Fever
- Some physiological causes of fever include:
- Infections
- Inflammatory reactions
- Tissue damage or necrosis
- Immune-mediated reactions
Markers of Fever
- The main marker associated with fever is an elevated white blood cell count (leukocytosis).
