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 the event of an injury that damages the skin's protective barrier, the body triggers a response called wound healing. After hemostasis, inflammation white blood cells, including phagocytic macrophages arrive at the injury site. Once the invading microorganisms have been brought under control, the skin proceeds to heal itself.
Hematomas can be subdivided by size. By definition, ecchymoses are 1 centimetres in size or larger, and are therefore larger than petechiae (less than 3 millimetres in diameter) [12] or purpura (3 to 10 millimetres in diameter). [13] Ecchymoses also have a more diffuse border than other purpura. [14]

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.

Chronic wounds may take years to heal or, in some cases, may never heal, causing significant physical and emotional stress for patients and placing a financial burden on healthcare systems. [7] Acute and chronic wounds are part of a spectrum, with chronic wounds requiring prolonged and complex care compared to acute wounds.
Devascularization or laceration involving 50% or more of the splenic parenchyma; Contrast blush greater than one centimeter in diameter (from active extravasation of IV contrast or pseudoaneurysm formation) A large hemoperitoneum. [1] Interactive tools have been developed that facilitate grading of splenic injury based on imaging findings.
“I have more than one moral injury and I used the easier one and not the bad ones that are really affecting me,” she said in December, eight months after she completed the program. What she told the group was “my small one,” about the Iraqi kids who would flock around U.S. troops and vehicles on patrol, begging for candy and cigarettes.
