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.
In prepubertal girls, the skin of the vulva is thin and delicate, and its neutral pH makes it prone to irritation. [51] The production of the female sex hormone estradiol (an estrogen) at puberty, causes the perineal skin to thicken by keratinising, and this reduces the risk of infection. [52]
Dermatophagia – extreme nail biting / biting of skin to point of an obsessive–compulsive disorder (OCD) [1] or other condition leading to self mutilating behaviour such as autistic spectrum disorders [citation needed] (as is the case in this example) or Lesch-Nyhan Syndrome.
So, when the surrounding temperature is higher than the skin temperature, anything that prevents adequate evaporation will cause the internal body temperature to rise. [4] During sports activities, evaporation becomes the main avenue of heat loss. [5] Humidity affects thermoregulation by limiting sweat evaporation and thus heat loss. [6]
A hand showing how acral gangrene of the fingers due to bubonic plague causes the skin and flesh to die and turn black An inguinal bubo on the upper thigh of a person infected with bubonic plague. Swollen lymph nodes ( buboes ) often occur in the neck, armpit and groin ( inguinal ) regions of plague victims.
A closeup of an erect micropenis with a tape measure displaying length. Of the abnormal conditions associated with micropenis, most are conditions of reduced prenatal androgen production or effect, such as abnormal testicular development (testicular dysgenesis), Klinefelter syndrome, Leydig cell hypoplasia, specific defects of testosterone or dihydrotestosterone synthesis (17,20-lyase ...
Breast hematomas can sometimes lead to skin discoloration, inflammation, or fever. When a hematoma resolves, it may become fibrotic, leaving behind scar tissue. A resolving hematoma may liquify to form a seroma. Post-surgical breast hematomas can also impede wound healing and therefore impact the cosmetic outcome.
Glaucoma may cause vision loss if left untreated. It has been called the "silent thief of sight" because the loss of vision usually occurs slowly over a long period of time. [5] A major risk factor for glaucoma is increased pressure within the eye, known as intraocular pressure (IOP). [1]
