Abscess
Classification & external resources | | | Abscess | | MeSH | D000038 | An abscess is a collection of pus that has accumulated in a cavity formed by the tissue on the basis of an infectious process (usually caused by bacteria or parasites) or other foreign materials (e.g. splinters or bullet wounds). It is a defensive reaction of the tissue to prevent the spread of infectious materials to other parts of the body. This article is about the musical genre. ...

The final structure of the abscess is an abscess wall, or capsule, that is formed by the adjacent healthy cells in an attempt to keep the pus from infecting neighboring structures. However, such encapsulation tends to prevent immune cells from attacking bacteria in the pus, or from reaching the causative organism or foreign object.
Abscesses must be differentiated from empyemas, which are accumulations of pus in a preexisting rather than a newly formed anatomical cavity. An empyema is a collection of pus within a natural body cavity. ...
Manifestations
The cardinal symptoms and signs of any kind of inflammatory process are redness, heat, swelling, pain and loss of function. Abscesses may occur in any kind of solid tissue but most frequently on skin surface (where they may be superficial pustules (boils) or deep skin abscesses), in the lungs, brain, kidneys and tonsils. Major complications are spreading of the abscess material to adjacent or remote tissues and extensive regional tissue death (gangrene). Abscesses in most parts of the body rarely heal themselves, so prompt medical attention is indicated at the first suspicion of an abscess. Boil or furuncle is a skin disease caused by the inflammation of hair follicles, thus resulting in the localized accumulation of pus and dead tissues. ...

Treatment
Antibiotics As Staphylococcus aureus bacteria is a common cause, an anti-Staphylococcus antibiotic such as Flucloxacillin or dicloxacillin is used. With the emergence of community-acquired methicillin-resistant Staphylococcus aureus MRSA, these traditional antibiotics may be ineffective; alternative antibiotics effective against community-acquired MRSA often include clindamycin, trimethoprim-sulfamethoxazole, and doxycycline. (However, if cellulitis rather than abscess, consideration should be given to possibility of strep species as cause that are still sensitive to traditional anti-Staphylococcus agents such as dicloxacillin or cephalexin.) It is important to note that antibiotic therapy alone without surgical drainage of the abscess is seldom effective due to antibiotics often being unable to get into the abscess and their ineffectiveness at low pH levels. Binomial name Rosenbach 1884 Staphylococcus aureus , (literally Golden Cluster Seed) the most common cause of staph infections, is a spherical bacterium, frequently living on the skin or in the nose of a person, that can cause a range of illnesses from minor skin infections (such as pimples, boils, and cellulitis...

Incision and drainage -
Main article: Incision and drainage The abscess should be inspected to identify if foreign objects are a cause, requiring surgical removal. If foreign objects are not the cause, a doctor will incise and drain the abscess and prescribe painkillers and possibly antibiotics. [citation needed]Surgical drainage of the abscess (e.g. lancing) is usually indicated once the abscess has developed from a harder serous inflammation to a softer pus stage. This is expressed in the Latin medical aphorism Ubi pus, ibi evacua. Incision and drainage is a minor surgical procedure to release pus or pressure built up under the skin, such as from an abscess or boil. ...

In critical areas where surgery presents a high risk, surgery may be delayed or used as a last resort. The drainage of a lung abscess may be performed by positioning the patient in a way that enables the contents to be discharged via the respiratory tract. Warm compresses and elevation of the limb may be beneficial for skin abscess. In humans the respiratory tract is the part of the anatomy that has to do with the process of respiration or breathing. ...
Primary closure Primary closure has been successful when combined with curettage and antibiotics[1] or with curettage alone.[2] However, another randomized controlled trial found primary closure led to 35% failing to heal primarily and primary closure longer median number of days to closure (8.9 versus 7.8).[3] In surgery, the use of a curette to remove tissue by scraping or scooping. ...

In anorectal abscesses, primary closure healed faster, but 25% of abscesses healed by secondary healing and recurrence was higher.[4]
Recurrent infections Recurrent abscesses are often caused by community-acquired MRSA. While resistant to most beta lactam antibiotics commonly used for skin infections, it remains sensitive to alternative antibiotics, ie clindamycin (Cleocin), trimethoprim-sulfamethoxazole (Bactrim), and doxycycline (unlike hospital-acquired MRSA that may only be sensitive to vancomycin IV).
To prevent recurrent infections due to [Staphylococcus], consider the following measures:
- Topical mupirocin applied to the nares [5]. In this randomized controlled trial, patients used nasal mupirocin twice daily 5 days a month for 1 year.
- Chlorhexidine baths [6], In a randomized controlled trial, nasal recolonization with S. aureus occurred at 12 weeks in 24% of nursing home residents receiving mupirocin ointment alone (6/25) and in 15% of residents receiving mupirocin ointment plus chlorhexidine baths daily for the first three days of mupirocin treatment (4/27). Although these results did not reach statistical significance, the baths are an easy treatment.

Perianal abscess Perianal abscesses can be seen in patients with for example inflammatory bowel disease (such as Crohn's disease) or diabetes. Often the abscess will start as an internal wound caused by ulceration or hard stool. This wound typically becomes infected as a result of the normal presence of feces in the rectal area, and then develops into an abscess. This often presents itself as a lump of tissue near the anus which grows larger and more painful with the passage of time. Note: This article is meant to generally encompass the conditions generally known variously as anal abscess, rectal abscess, peri-rectal abscess and peri-anal abscess. ...
