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.
Typically, wounds that do not heal within three months are classified as chronic. [1] Chronic wounds may remain in the inflammatory phase due to factors like infection or bacterial burden, ischaemia, presence of necrotic tissue, improper moisture balance of wound site, or underlying diseases such as diabetes mellitus. [2] [3] [4]
As with the licking of wounds by people, wound licking by animals carries a risk of infection. Allowing pet cats to lick open wounds can cause cellulitis [53] [54] and sepsis [55] [56] due to bacterial infections. Licking of open wounds by dogs could transmit rabies if the dog is infected with rabies, [57] although this is said by the CDC to be ...
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.

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.
Chronic wound pain is a condition described as unremitting, disabling, and recalcitrant pain experienced by individuals with various types of chronic wounds. [1] Chronic wounds such as venous leg ulcers, arterial ulcers, diabetic foot ulcers, pressure ulcers, and malignant wounds can have an enormous impact on an individual’s quality of life with pain being one of the most distressing symptoms.
Some troops leave the battlefield injured. Others return from war with mental wounds. Yet many of the 2 million Iraq and Afghanistan veterans suffer from a condition the Defense Department refuses to acknowledge: Moral injury.
In recent years, advances have been made in accelerating healing of chronic wounds and ulcers. Chronic wounds produce fewer growth hormones than necessary for healing tissue, and healing may be accelerated by replacing or stimulating growth factors while controlling the formation of other substances that work against them.
