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.
For instance, in wound healing, P21 has been found to allow mammals to heal spontaneously. It even allows some mammals (like mice) to heal wounds without scars. [5] [6] The LIN28 gene also plays a role in wound healing. It is dormant in most mammals. [7] Also, the proteins MG53 and TGF beta 1 play important roles in wound healing. [8]
Abrasions on elbow and lower arm. The elbow wound will produce a permanent scar. A first-degree abrasion involves only epidermal injury. A second-degree abrasion involves the epidermis as well as the dermis and may bleed slightly. A third-degree abrasion involves damage to the subcutaneous layer and the skin and is often called an avulsion.
After having patients describe in painful detail what caused their moral injury, therapists asked them to choose someone they saw as a compassionate moral authority and hold an imaginary conversation with that person, describing what happened and the shame they feel. They were then asked to verbalize the response, using their imagination.
A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease. [3]
The wound usually appears red and can be accompanied by drainage. Clinicians delay re-opening the wound unless it is necessary due to the potential of other complications. If the surgical wound worsens, or if a rupture of the digestive system is suspected the decision may be to investigate the source of the drainage or infection. [2] [3]
Scarification is not a precise practice; variables, such as skin type, cut depth, and how the wound is treated while healing, can make the outcome unpredictable compared to other forms of body modification. A method that works on one person may not work on another.
A dressing or compress [1] is a piece of material such as a pad applied to a wound to promote healing and protect the wound from further harm. A dressing is designed to be in direct contact with the wound, as distinguished from a bandage, which is most often used to hold a dressing in place. Modern dressings are sterile.
