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.

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.

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.

heat illness

the term used to describe the spectrum of conditions which result from the effects of excessive heat, whilst hyperthermia refers to any elevation of the body (core) temperature above normal. Heat problems are influenced by humidity, which reduces heat loss by evaporation. Young children have less ability to lose heat by sweating and are therefore more susceptible. heat cramps muscle cramps with general fatigue that occur after exercise, associated with profuse sweating and the resulting salt loss. Treatment is removal from the hot environment, plus salt and water replacement. heat exhaustion is the most common heat illness in sport. Symptoms are often vague and include faintness, loss of co-ordination, profuse sweating, headache, nausea, dizziness and thirst. It is related to alterations in fluid/electrolyte balance and changes in blood volume. Treatment is removal from the hot environment, external cooling, elevation of the legs, fluid replacement and careful monitoring of airway, breathing and circulation (ABC). heat syncope occurs with postural pooling of blood and a decrease in venous return resulting in relative cerebral hypoperfusion. It occurs most commonly with a sudden rise in temperature or humidity. Salt and water depletion are less common than in the other types of heat illness. heat stroke is rare but can be fatal; it is at the end of the spectrum of heat illness when the body temperature continues to rise as heat loss by sweating fails due to dehydration; the result is collapse, possible seizures, coma and death. It is a medical emergency and should be treated as such with immediate admission to hospital.

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.
