Once the invading microorganisms have been brought under control, the skin proceeds to heal itself. The ability of the skin to heal even after considerable damage has occurred is due to the presence of stem cells in the dermis and cells in the stratum basale of the epidermis, all of which can generate new tissue.
If the abscess does not heal only with incision and drainage, or if the abscess is in a place that is difficult to drain such as the face, hands, or genitals, then antibiotics may be indicated. [ 1 ] In those cases of abscess which do require antibiotic treatment, Staphylococcus aureus bacteria is a common cause and an anti-staphylococcus ...
The wound can be allowed to close by secondary intention. Alternatively, if the infection is cleared and healthy granulation tissue is evident at the base of the wound, the edges of the incision may be reapproximated, such as by using butterfly stitches , staples or sutures .
Emotional stress can also negatively affect the healing of a wound, possibly by raising blood pressure and levels of cortisol, which lowers immunity. [7] What appears to be a chronic wound may also be a malignancy; for example, cancerous tissue can grow until blood cannot reach the cells and the tissue becomes an ulcer. [13]
A dental abscess is a localized collection of pus associated with a tooth. The most common type of dental abscess is a periapical abscess, and the second most common is a periodontal abscess. In a periapical abscess, usually the origin is a bacterial infection that has accumulated in the soft, often dead, pulp of the tooth.
Pus from anaerobic infections can more often have a foul odor. [8] In almost all cases when there is a collection of pus in the body, a clinician will try to create an opening to drain it. This principle has been distilled into the famous Latin aphorism " Ubi pus, ibi evacua" ("Where there is pus, evacuate it").
Often it is associated with focal bacterial or fungal infections, and can also manifest as one of the symptoms of an internal chemical burn. [2] In liquefactive necrosis, the affected cell is completely digested by hydrolytic enzymes , resulting in a soft, circumscribed lesion consisting of pus and the fluid remains of necrotic tissue.
The existing epithelial cells can replicate, and, using the basement membrane as a guide, eventually bring the kidney back to normal. After regeneration is complete, the damage is undetectable, even microscopically. [citation needed] Healing must happen by repair in the case of injury to cells that are unable to regenerate (e.g. neurons).
