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]
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 her 1974 book Questions and Answers on Death and Dying, Kübler-Ross had by then observed that the stages are not experienced in a strictly linear progression. She noted, 'Most of my patients have exhibited two or three stages simultaneously, and these do not always occur in the same order.' [ 15 ] She later regretted writing them in a way ...
In 2011, the scientific literature highlighted stress shielding a fresh wound through the wound healing process, brings significant scar improvement and smaller scars. [ 18 ] [ 35 ] By 2016, skin had been regenerated in vivo and in vitro . and scar-free healing had been operationalized and induced by four main regeneration techniques: by ...
French barber-surgeon Ambroise Paré was the first to describe different degrees of burns in the 1500s. [17] Guillaume Dupuytren expanded these degrees into six different severities in 1832. [14] [18] The first hospital to treat burns opened in 1843 in London, England, and the development of modern burn care began in the late 1800s and early 1900s.
The periwound (also peri-wound) is tissue surrounding a wound. Periwound area is traditionally limited to 4 cm outside the wound's edge but can extend beyond this limit if outward damage to the skin is present. Periwound assessment is an important step of wound assessment before wound treatment is prescribed. [1]
Other styles are also used in news writing, including the "anecdotal lead", which begins the story with an eye-catching tale or anecdote rather than the central facts; and the Q&A, or question-and-answer format. The inverted pyramid may also include a "hook" as a kind of prologue, typically a provocative quote, question, or image, to entice the ...
In microangiopathy, neuropathy and autoregulation of capillaries leads to poor perfusion of tissues, especially wound base. When pressure is placed on the skin, the skin is damaged and is unable to be repaired due to the lack of blood perfusing the tissue. The wound has a characteristic deep, punched out look, often extending down to the ...
