Research into hormones and wound healing has shown estrogen to speed wound healing in elderly humans and in animals that have had their ovaries removed, possibly by preventing excess neutrophils from entering the wound and releasing elastase. [26] Thus the use of estrogen is a future possibility for treating chronic wounds.
Toenails which protrude unevenly may concentrate force on the toenail; properly-cut nails are therefore also important. [4] Some susceptible runners may also have Morton's toe. In this variant of human foot anatomy, the second toe extends further out than the great toe. This can make it harder to find shoes with adequate space around the toes.
Frictional alopecia is the loss of hair that is caused by rubbing of the hair, follicles, or skin around the follicle. [1] The most typical example of this is the loss of ankle hair among people who wear socks constantly for years. [2] The hair may not grow back even years after the source of friction has ended.
Andrew Walker was struggling with fatigue and the inability to heal from minor cuts and injuries when doctors discovered he had bowel cancer
His ankle began to swell two days later — the start of a life-threatening sepsis infection that would lead to his legs being amputated below the knee With the help of prosthetics, he hopes to be ...
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 a major injury, if epithelial cell migration and tissue contraction cannot cover the wound, suturing the edges of the injured skin together, or even replacement of lost skin with skin grafts, may be required to restore the skin. As epithelial cells continue to migrate around the scab, the dermis is repaired by the activity of stem cells.
The affected toe can no longer receive an adequate blood supply via the arteries, nor can blood be drained via the veins. The toe will therefore swell and turn blue, indicating ischemia . The ligature will not stretch in response to the toe swelling and will therefore cut into the skin in more severe cases, like a cheese-wire.
