Magnetic hyperthermia is an experimental treatment for cancer, based on the fact that magnetic nanoparticles can transform electromagnetic energy from an external high-frequency field to heat. [21] This is due to the magnetic hysteresis of the material when it is subjected to an alternating magnetic field. [22] The area enclosed by the ...
Therefore, it is usually the smallest or sharpest electrode that generates the most heat. Cut/Coag Most wet field electrosurgical systems operate in two modes: "Cut" causes a small area of tissue to be vaporized, and "Coag" causes the tissue to "dry" (in the sense of bleeding being stopped). "Dried" tissues are killed (and will later slough or ...
The same techniques are also used to create higher tissue temperatures to destroy neoplasms (cancer and tumors), warts, and infected tissues; this is called hyperthermia treatment. In surgery diathermy is used to cauterize blood vessels to prevent excessive bleeding. The technique is particularly valuable in neurosurgery and surgery of the eye.
Heat therapy is also sometimes used in cancer treatment to augment the effect of chemotherapy or radiotherapy, but it is not enough to kill cancer cells on its own. [ 15 ] Heat therapy has been shown to be beneficial in treating sub-acute and chronic musculoskeletal pain, but the choice to use heat therapy to treat acute musculoskeletal ...
Medical applications of radio frequency (RF) energy, in the form of electromagnetic waves (radio waves) or electrical currents, have existed for over 125 years, [1] and now include diathermy, hyperthermy treatment of cancer, electrosurgery scalpels used to cut and cauterize in operations, and radiofrequency ablation.

Heat stroke is an acute temperature elevation caused by exposure to excessive heat, or combination of heat and humidity, that overwhelms the heat-regulating mechanisms of the body. The latter is a relatively rare side effect of many drugs, particularly those that affect the central nervous system .
Local cold-water swim clubs and ice bath clubs offer a social way to experience cold-water immersion. Thanks to social media and groups like Swimmable Cities, it's easier than ever to find these ...
When a bone is cut during surgery bleeding can be a difficult problem to control, especially in the highly vascular bones of the spine and sternum. Bleeding from soft tissue is normally stopped using a cautery that creates heat, causing blood vessels to collapse and become sealed. Since the blood in living bone flows through channels in the ...
