The fungal species responsible for causing tinea capitis vary according to the geographical region, and may also change over time. For example, Microsporum audouinii was the predominant etiological agent in North America and Europe until the 1950s, but now Trichophyton tonsurans is more common in the US, and becoming more common in Europe and ...
Dermatophytosis, also known as tinea and ringworm, is a fungal infection of the skin [2] (a dermatomycosis), that may affect skin, hair, and nails. [1] Typically it results in a red, itchy, scaly, circular rash. [1] Hair loss may occur in the area affected. [1] Symptoms begin four to fourteen days after exposure. [1]
The exact mechanism of action of silicone gel sheeting has not been fully studied. Currently, many proposed mechanisms explain the efficacy of such treatment, including the occlusion and hydration effect, increased body surface temperature, polarized electric charge, immunological effects, etc. [9] The occlusion and hydration effect is the most studied mechanism of action.
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable.
In 1976, after 82 days of consecutive injections into a scar, purified insulin was shown to safely regenerate fat and completely regenerate skin in a non-diabetic. [ 4 ] [ 5 ] During a high-fat diet, and during hair follicle growth, mature adipocytes (fats) are naturally formed in multiple tissues. [ 42 ]
Keloid scars can develop after surgery. They are more common in some sites, such as the central chest (from a sternotomy), the back and shoulders (usually resulting from acne), and the ear lobes (from ear piercings). They can also occur on body piercings. The most common spots are earlobes, arms, pelvic region, and over the collar bone.
A hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which gives rise to a raised scar, but not to the degree observed with keloids. [1] Like keloids, they form most often at the sites of pimples, body piercings , cuts and burns.
