hyperthermia

 [hi″per-ther´me-ah]
1. greatly increased temperature; see also fever. Called also hyperpyrexia. adj., adj hyperther´mal, hyperther´mic.
2. a nursing diagnosis accepted by the North American Nursing Diagnosis Association, defined as the state in which an individual's body temperature is elevated above his or her normal range.
malignant hyperthermia a syndrome affecting patients undergoing general anesthesia, marked by rapid rise in body temperature, signs of increased muscle metabolism, and usually rigidity. The sensitivity is inherited as an autosomal dominant trait.

hy·per·ther·mi·a

(hī-per-ther'mē-ă),
Therapeutically or iatrogenically induced hyperpyrexia.
[hyper- + G. thermē, heat]

/hy·per·ther·mia/ (-ther´me-ah) hyperpyrexia; greatly increased body temperature.hyperther´malhyperther´mic
malignant hyperthermia  an autosomal dominant inherited condition affecting patients undergoing general anesthesia, marked by sudden, rapid rise in body temperature, associated with signs of increased muscle metabolism, and, usually, muscle rigidity.

Usage notes: nontechnical.
malignant hyperthermia.
3 the use of various heating methods, such as electromagnetic therapy, to produce temperature elevations of a few degrees in cells and tissues. It is believed to lead to an antitumor effect. Hyperthermia may be used in conjunction with radiotherapy or chemotherapy for cancer treatment.

hyperthermia

Hyperpyrexia Mainstream medicine A condition defined as a corporal temperature of ≥ 42ºC; the body defends itself with peripheral vasodilation–↓ effective volume, resulting in ↑ pulse rate–a response to perceived blood loss, ↓ cardiac efficiency, hypoxia, ↑ permeability of cell membranes with ↑ potassium, followed by cardiac failure. See Malignant hyperthermia Oncology A type of treatment in which tissue is exposed to high temperatures to damage and kill CA cells, or ↑ CA cell sensitivity to RT and chemotherapy. See Induced hyperthermia, Malignant hyperthermia.

hy·per·ther·mi·a

(hī'pĕr-thĕr'mē-ă, hīpĕr-thĕrmē-ă)
Hyperpyrexia, often (but not necessarily) induced therapeutically; denotes bodily state with core body temperature significantly above 98.6°F (37°C); term may indicate temperature sufficiently elevated to cause illness.

hyperthermia

1. greatly increased body temperature. May have effect as teratogen.
2. heat therapy. Used in the treatment of tumors, often in conjunction with chemotherapy or radiation. Whole body, regional or localized hyperthermia is induced with electromagnetic radiation, radiofrequency current heating or ultrasonic heating.

epidemic hyperthermia
poisoning by Neotyphodium (Acremonium)coenophialum.
idiopathic hyperthermia
term applied in error to the effects of ergotism under conditions of high ambient temperature. See also rye ergot, Neotyphodium(Acremonium) coenophialum.
malignant hyperthermia
a drug induced stress syndrome of pigs which have been treated with halothane or suxamethonium. Isolated cases have been reported in dogs and cats. The clinical syndrome includes muscle rigidity and hyperthermia. It is fatal and susceptibility to it is inherited. See also porcine stress syndrome.
