Hyperthermia is generally diagnosed by the combination of unexpectedly high body temperature and a history that supports hyperthermia instead of a fever. [2] Most commonly this means that the elevated temperature has occurred in a hot, humid environment (heat stroke) or in someone taking a drug for which hyperthermia is a known side effect ...
Drug-induced fever is a symptom of an adverse drug reaction wherein the administration of drugs intended to help a patient causes a hypermetabolic state resulting in fever. The drug may interfere with heat dissipation peripherally, increase the rate of metabolism , evoke a cellular or humoral immune response , mimic endogenous pyrogen , or ...
On the other hand, a "normal" temperature may be a fever, if it is unusually high for that person; for example, medically frail elderly people have a decreased ability to generate body heat, so a "normal" temperature of 37.3 °C (99.1 °F) may represent a clinically significant fever.
Pyrotherapy (artificial fever) is a method of treatment by raising the body temperature or sustaining an elevated body temperature using a fever. In general, the body temperature was maintained at 41 °C (105 °F). [1] Many diseases were treated by this method in the first half of the 20th century.
Fever (high body temperature) Flushing (redness) of the face and chest; Hemorrhage (bleeding) and sometimes bleeding diathesis (a person loses more blood than usual from an injury – for example, getting only a little cut, and losing a lot of blood) Malaise (a general feeling that you are sick) Myalgia (muscle pain)
Polymer fume fever or fluoropolymer fever, also informally called Teflon flu, is an inhalation fever caused by the fumes released when polytetrafluoroethylene (PTFE, known under the trade name Teflon) reaches temperatures of 300 °C (572 °F) to 450 °C (842 °F).
Fever of unknown origin (FUO) refers to a condition in which the patient has an elevated temperature for which no cause can be found despite investigations by one or more qualified physicians. [ 1 ] [ 2 ] [ 3 ] If the cause is found, it is usually a diagnosis of exclusion , eliminating all possibilities until only the correct explanation remains.
The standard procedure is the "caffeine-halothane contracture test", CHCT. A muscle biopsy is carried out at an approved research center, under local anesthesia. The fresh biopsy is bathed in solutions containing caffeine or halothane and observed for contraction; under good conditions, the sensitivity is 97% and the specificity 78%. [ 26 ]
