The depth of penetration depends on the frequency of the microwaves and the tissue type. The Active Denial System ("pain ray") is a less-lethal directed energy weapon that employs a microwave beam at 95 GHz; a two-second burst of the 95 GHz focused beam heats the skin to a temperature of 130 °F (54 °C) at a depth of 1/64th of an inch (0.4 mm) and is claimed to cause skin pain without lasting ...
Erythema ab igne in a person with chronic abdominal pain who found some relief from the application of heat. Erythema ab igne (Latin for 'redness from fire') EAI, also known as hot water bottle rash, [2] is a skin condition caused by long-term exposure to heat (infrared radiation). [3] Prolonged thermal radiation exposure to the skin can lead ...
A radiation burn is a damage to the skin or other biological tissue and organs as an effect of radiation. The radiation types of greatest concern are thermal radiation, radio frequency energy, ultraviolet light and ionizing radiation. The most common type of radiation burn is a sunburn caused by UV radiation.
Phonophoresis can be performed using two main methods: The first is simultaneous treatment, where the drug can be applied at the same time as the ultrasound. The second method is pretreatment, where the ultrasound is used briefly before drug delivery. [8] [9] [13] [7] This is to ensure that the skin is permeable prior to the drug being applied.
Treatment. Surgical drain. A seroma is a pocket of clear serous fluid (filtered blood plasma). They may sometimes develop in the body after surgery, particularly after breast surgery, abdominal surgery, and reconstructive surgery. They can be diagnosed by physical signs, and with a CT scan. Seromas can be difficult to manage.
Ultraviolet light can cause burns to skin [15] and cataracts to the eyes. [15] Ultraviolet is classified into near, medium and far UV according to energy, where near and medium ultraviolet are technically non-ionizing, but where all UV wavelengths can cause photochemical reactions that to some extent mimic ionization (including DNA damage and ...
Actinic keratosis (AK), sometimes called solar keratosis or senile keratosis, [ 1 ][ 2 ] is a pre-cancerous [ 3 ] area of thick, scaly, or crusty skin. [ 4 ][ 5 ] Actinic keratosis is a disorder (-osis) of epidermal keratinocytes that is induced by ultraviolet (UV) light exposure (actin-). [ 6 ] These growths are more common in fair-skinned ...
Frostbite is a skin injury that occurs when someone is exposed to extremely low temperatures, causing the freezing of the skin or other tissues, [1] commonly affecting the fingers, toes, nose, ears, cheeks and chin areas. [6] Most often, frostbite occurs in the hands and feet. [7][8] The initial symptoms are typically a feeling of cold and ...
