Bacterial cellulitis

The goal of therapy of acute bacterial cellulitis is rapid eradication of the infection and prevention of further complications. 

Antimicrobial therapy of bacterial cellulitis is directed toward the type of bacteria either documented to be present or suspected. 

It is important to note that the acute lid edema occurring soon after the onset of viral invasion does not result from bacterial cellulitis and typically resolves within a few days without antibiotic therapy. 

The goal of therapy of acute bacterial cellulitis is rapid eradication of the infection and prevention of further complications. Antimicrobial therapy of bacterial cellulitis is directed against the type of bacteria either documented or suspected to be present based on the clinical presentation. Local care of cellulitis includes elevation and immobilization of the involved area to decrease swelling. Cool sterile saline dressings can decrease pain and can be followed later with moist heat to aid in localization of the cellulitis. Surgical intervention (incision and drainage) as a mode of therapy is rarely indicated in the treatment of cellulitis. 

Infection risk Two injection site reactions to subcutaneous anakinra have been reported Wells cellulitis of the thigh and a bacterial cellulitis with deep necrosis [84 ]. 

Deoxyribonuclease (DNAase), an enzyme that degrades deoxyribonucleic acid, has been used in patients with chronic bronchitis, and found to produce favorable responses presumably by degrading the DNA, contributed by cell nuclei, to inflammatory mucus (213). Lysozyme [9001 -63-2] hydrolyzes the mucopeptides of bacterial cell walls. Accordingly, it has been used as an antibacterial agent, usually in combination with standard antibiotics. Topical apphcations are also useful in the debridement of serious bums, cellulitis, and dermal ulceration. 

Cellulitis is a bacterial infection of the dermis and subcutaneous tissue. S. aureus and P-hemolytic streptococci are the most common causes of acute cellulitis in otherwise healthy hosts. Persons who are immunocompromised, have vascular insufficiency, or use injection drugs are at risk for polymicrobial cellulitis. 

Cellulitis and erysipelas are bacterial infections of the skin. Although separate entities, there is some clinical difficulty in distinguishing the two. 0 Cellulitis is a bacterial infection of the dermis and subcutaneous tissue, whereas erysipelas is a more superficial infection of the upper dermis and superficial lymphatics. Although both can occur on any part of the body, about 90% of infections involve the leg.8,9 Another 7.5% of cases involve the arm or face. Erysipelas is most common in the young and the elderly. Typically, both infections develop after a break in skin integrity, resulting from trauma, surgery, ulceration, burns, tinea infection, or other skin disorder. 

Onychomycosis is a chronic infection that rarely remits spontaneously. Adequate treatment is essential to prevent spread to other sites, secondary bacterial infections, cellulitis, or gangrene. Due to the chronic nature and impenetrability of nails, topical agents have low efficacy rates for treating onychomycosis. Oral agents that can penetrate the nail matrix and nail base, such as itraconazole and terbinafine, are more effective than ciclopirox lacquer. Itraconazole and terbinafine demonstrate mycological cure rates of 62%37 and 76%,38 respectively, while ciclopirox has a cure rate of 29% to 36%.39... 

Hypersensitivity to any component monotherapy in primary bacterial infections such as impetigo, paronychia, erysipelas, cellulitis, angular cheilitis, erythrasma (clobetasol), treatment of rosacea, perioral dermatitis, or acne use on the face, groin, or axilla (very high or high potency agents) ophthalmic use.

Bacterial superficial skin infections including cellulitis and erysipelas, furunculosis and impetigo usually have a benign course. Infections of the subcutis often lead to necrosis of soft tissue. These infections are described in section 16 (surgical infections). Arthritis involves infection of the synovia and... 

Serious adverse events occur in up to 6% of patients with anti-TNF therapy. The most important adverse effect of these drugs is infection due to suppression of the ThI inflammatory response. This may lead to serious infections such as bacterial sepsis, tuberculosis, invasive fungal organisms, reactivation of hepatitis B, listeriosis, and other opportunistic infections. Reactivation of latent tuberculosis, with dissemination, has occurred. Before administering anti-TNF therapy, all patients must undergo purified protein derivative (PPD) testing prophylactic therapy for tuberculosis is warranted for patients with positive test results. More common but usually less serious infections include upper respiratory infections (sinusitis, bronchitis, and pneumonia) and cellulitis. The risk of serious infections is increased markedly in patients taking concomitant corticosteroids. 

Cellulitis is a skin infection of the dermis and subcutaneous tissues. It is characterised by redness, swelling, pain and inflammation. A common symptom is fever. Cellulitis is caused by bacterial infection, most commonly Streptococcus (group A) and Staphylococcus. 

Orbital cellulitis is an infection of the orbital contents posterior to the orbital septum. Streptococci and staphylococci are common bacterial isolates. Many regimens exist for empiric treatment of this disease, but no regimen has been tested in clinical trials. Intravenous nafcillin can be used as initial therapy for orbital cellulitis, especially when a staphylococcal infection is suspected or known (see Table 11-1). 

Cefeclor is nsed to treat bacterial infections of the middle ear, limg, and urinary tract. Oral cefeclor can also be used to treat mild preseptal celluUtis. Parenteral administration of cefuroxime along with ampicillin/snlbactam is a recommended treatment for severe or imresponsive preseptal cellulitis (see Table 11-1). However, with the increase of penicillin-resistant isolates of Streptococcus pneumoniae, the effectiveness of empirically treating this condition with p-lactam dmgs needs to be carefully considered. 

Methicillin-resistant strains of Staphylococcus aureus and S. epidermidis and penicillin-resistant Streptococcus pneumoniae have been isolated from ocular infections. Therefore treatment of ocular infections caused by these organisms might require use of vancomycin for resolution. Vancomycin is also recommended for empiric intra-vitreal and topical therapy in bacterial endophthalmitis and for parenteral therapy in moderate to severe preseptal cellulitis (see Table 11-1). 

Deep bacterial infections, e.g. boils, generally do not require antimicrobial therapy but if they do it should be systemic. Cellulitis requires systemic chemotherapy initially with benzylpeniciUin and flucloxacillin. 

A 25-year-old Chinese woman with systemic lupus erythematosus had a disease course characterized by multiple flares involving the kidneys, central nervous system, and gastrointestinal tract (26). She was given mycophenolate mofetil and multiple courses of antibiotics, with a poor response. After about 9 months she developed a recurrent right leg cellulitis. Two initial skin biopsies yielded negative bacterial and mycobacterial cultures, but histopathology of the muscle of... 

Bacterial infection of the skin and subcutaneous tissue can lead to rapidly spreading inflammation known as cellulitis, which requires systemic antibacterial treatment. Treatment is usually with benzylpenicillin and flucloxacillin or erythromycin. 

Bacterial infection of the skin causes a condition known as cellulitis, which requires systemic antibiotics. As does impetigo if it is extensive, although small patches can be treated topically. Silver sulfadiazine is used prophylactically to prevent infection in burns and other wounds and is now on the list of antibiotics that qualified registered podiatrists can access and supply. 

Deeper bacterial infections of the skin include folliculitis, erysipelas, cellulitis, and necrotizing fasciitis. Since streptococcal and staphylococcal species also are the most common causes of deep cutaneous infections, penicilUns (especially ji-lactarruise-resistant ji-lactams), and cephalosporins are the systemic antibiotics used most frequently in their treatment (see Chapter 44). A growing concern is the increased incidence of skin and soft tissue infections with hospital- and community-acquired methicillin-resistant S. aureus (MRSA) and drug-resistant pneumococci. Infection with community-acquired MRSA often is susceptible to trimethoprim—sulfamethoxazole.
