Pyomyositis is the presence of pus within individual muscle groups, caused mainly by S. aureus. Patients with temperature >38.5°C or heart rate >110 beats/minute or erythema extending beyond the wound margins for >5 cm may require a short course (eg, 24–48 hours) of antibiotics, as well as opening of the suture line (Figure 2). The goal of most chronic wound care should be eventual wound closure with or without grafts, skin replacements, or other surgery (such as amputation, wound excision, etc. Severe pain may be the initial clinical symptom with little cutaneous evidence due to the deep infection. All other authors report no potential conflicts. What is the appropriate approach to the management of pyomyositis? Figure 2 presents a schematic algorithm to approach patients with suspected SSIs and includes specific antibiotic recommendations [105]. Extensive undermining of surrounding tissues is usually present, and the tissue planes can be readily dissected with a gloved finger or a blunt instrument. 2. These later infections are most common among high-risk patients with prolonged and profound neutropenia and they should be considered in any patient with neutropenia and skin and soft tissue lesions suggestive of infection. 1, 2 The frequency of wound infection is less than 1% in women undergoing postpartum sterilization, interval sterilization, or other operative laparoscopy procedures. In such infections, immediate surgical exploration by a team experienced in the management of these patients and broad-spectrum antibiotic therapy targeted at gram-negative, gram-positive, and anaerobic bacteria are essential. This guideline covers preventing and treating surgical site infections in adults, young people and children who are having a surgical procedure involving a cut through the skin. 16. What Is the Appropriate Evaluation and Treatment for Purulent SSTIs (Cutaneous Abscesses, Furuncles, Carbuncles, and Inflamed Epidermoid Cysts)? Other indications include poor response to outpatient therapy, severe immunocompromise, and problems with a patient's adherence to treatment. Postoperative infection remains the most common complication of gynaecological surgical procedures. Streptomycin has been considered the drug of choice for tularemia for several decades [130]. Acute Care Surgery is a comprehensive textbook covering the related fields of trauma, critical care, and emergency general surgery. Investigations are needed to determine the pathogenesis of soft tissue infections caused by streptococci. In these cases the wound is often deceptively benign in appearance. Superficial Surgical Site Infections Infections involving the subcutaneous tissue within 30 days of operation For SSI involving deep tissue or organ space or complicated by sepsis/septic shock, see below or organ specific guidelines (Intra-abdominal, Gynecology, Meningitis, Endocarditis, Bone and Joint) response to Suture removal plus incision and Prophylactic or early preemptive therapy seems to provide marginal benefit to wound care for patients with dog bites who present within 12–24 hours after injury, particularly in low-risk wounds—that is, those that are not associated with puncture wounds; those in patients with no history of an immunocompromising disorder or use of immunosuppressive drugs; or wounds not involving the face, hand, or foot [149–152]. The bacteriologic characteristics of these wounds are complex, but include aerobic bacteria, such as streptococci, S. aureus, and Eikenella corrodens, as well as with multiple anaerobic organisms, including Fusobacterium, Peptostreptococcus, Prevotella, and Porphyromonas species. Amphotericin B is an excellent alternative. SMX-TMP remains the treatment of choice, but other sulfa antibiotics (eg, sulfadiazine and sulfasoxazole), amikacin, imipenem, meropenem, third-generation cephalosporins (ceftriaxone and cefotaxime), minocycline, extended-spectrum fluoroquinolones (eg, moxifloxacin), linezolid, and dapsone are effective in vitro and in animal models (Table 6). Definitive treatment of SSTIs caused by staphylococci and streptococci in terms of preferred agents, doses, and duration of therapy is needed to improve outcomes and potentially reduce antibiotic exposure. Most patients can receive treatment without hospitalization [63, 64]. Blood-borne HSV dissemination, manifested by multiple vesicles over a widespread area of the trunk or extremities, is uncommon, but when seen among compromised hosts, it is usually secondary to an HSV-2 infection. Intravenous acyclovir should be added to the empiric antimicrobial regimen of the rare patient who has not been receiving antiviral prophylaxis effective against HSV or VZV, but has developed skin lesions suspected or confirmed to be caused by these viruses. The appropriate antibiotics for patients with suspected or confirmed SSTI (initial infection) should be broad-spectrum agents administered at the first clinical signs or symptoms of infection [203]. Epidemiology, definition & classification. Woods RK, Dellinger EP. Larger clinical trials should determine if anti-inflammatory agents are useful or detrimental in the treatment of cellulitis and erysipelas. S����N �ȼ ��� H �$���r�z��6��A��e|Y��"� Numerous studies highly variable in quality and employing diverse and nonstandardized approaches to basic wound care and a variety of antimicrobial agents, have failed to definitively determine who should receive early, preemptive therapy for bite wounds. Gram stains of the exudate will demonstrate the pathogens and provide an early guide to antimicrobial therapy. This book focuses exclusively on the surgical patient and on the perioperative environment with its unique socio-technical and cultural issues. What Is the Treatment for Infected Animal Bite–Related Wounds? Cutaneous manifestations of acute progressive disseminated histoplasmosis are rare and usually occur in patients with severe cellular immune deficiency [237, 238]. What Is the Preferred Management of Surgical Site Infections? Superficial incisional SSIs involve only the subcutaneous space, between the skin and underlying muscular fascia, occur within 30 days of the surgery, and are documented with at least 1 of the following: (1) purulent incisional drainage, (2) positive culture of aseptically obtained fluid or tissue from the superficial wound, (3) local signs and symptoms of pain or tenderness, swelling, and erythema after the incision is opened by the surgeon (unless culture negative), or (4) diagnosis of SSI by the attending surgeon or physician based on their experience and expert opinion. The clinician must ensure that a deeper infection such as necrotizing fasciitis is not present. The benefits of regular tetanus toxoid boosters in adults who have had a primary series have been questioned although its use in “dirty wounds” seems sensible [161, 162]. Patients without a preceding history of VZV exposure are at signicant risk of developing severe chickenpox if exposed, but herpes zoster (also known as shingles) with or without dissemination is a more frequent clinical concern. Nearly 50% of patients with necrotizing fasciitis caused by S. pyogenes have no portal of entry but develop deep infection at the exact site of nonpenetrating trauma such as a bruise or muscle strain. Clindamycin suppresses streptococcal toxin and cytokine production. The most important diagnostic feature of necrotizing fasciitis is the appearance of the subcutaneous tissues or fascial planes at operation. The risk for an infection in this type of wound is usually less than 2%. For C. glabrata and C. krusei, use echinocandins as first line. Local complications include destruction of tissue, wound dehiscence, incisional and deep hernias, septic thrombophlebitis, recurrent pain, and disfiguring and disabling scars. XXIII. Treatment of experimental gas gangrene has demonstrated that tetracycline, clindamycin, and chloramphenicol are more effective than penicillin [137, 138]. Use of antimicrobial prophylaxis in these patients has shown to ultimately impact the pathogens that will be isolated when infection develops, and this information should be available to the clinician when assessing immunocompromised patients with skin and soft tissue lesions [182, 183]. S. L. K. has served as a consultant to Novartis, Pfizer, and Wyeth; has been a site PI for Cubist, Cerexa, and Optimer; and has received honoraria from UpToDate and Merck. Therefore, this section of the SSTI guideline will focus on existing recommendations that demand reinforcement, or that are truly specific to SSTIs. Samples of the pus may be grown in a culture to find out the types of germs . Serum creatine kinase concentrations are typically normal in patients with a single area of pyomyositis related to hematogenous seeding of muscle [124]. Treatment of yeast and mold infections should follow IDSA and NCCN guideline recommendations [187, 189]. For the first infection with all Candida spp except C. glabrata and C. krusei, use fluconazole as first line. This highly illustrated text covers the full range of infections that pose such a challenge in the care of patients undergoing a surgical procedure. What Is the Appropriate Antibiotic Therapy for Patients With SSTIs During the Initial Episode of Fever and Neutropenia? Isolation of Aspergillus from blood cultures is rare, but dissemination is commonly detected at autopsy [224]. Broader empirical coverage for abscesses might yield better therapeutic results. Diagnosis of Bartonella infections may be difficult because the organism is fastidious and difficult to grow in culture. After 48 hours, SSI is a more common source of fever, and careful inspection of the wound is indicated; by 4 days after surgery, a fever is equally likely to be caused by an SSI or by another infection or other unknown sources [80]. Bubonic plague, the most common and classic form, develops when humans are bitten by infected fleas or have a breach in the skin when handling infected animals. Therefore, treatment with amoxicillin-clavulanate, ampicillin-sulbactam, or ertapenem is recommended; if there is history of hypersensitivity to β-lactams, a fluoroquinolone, such as ciprofloxacin or levofloxacin plus metronidazole, or moxifloxacin as a single agent is recommended. High-dose IV acyclovir remains the treatment of choice for VZV infections in compromised hosts. What Is the Appropriate Approach to the Evaluation and Treatment of Clostridial Gas Gangrene or Myonecrosis? 2. Eat to Beat Disease isn't about what foods to avoid, but rather is a life-changing guide to the hundreds of healing foods to add to your meals that support the body's defense systems, including: Plums Cinnamon Jasmine tea Red wine and beer ... VZV in compromised hosts may present with the traditional unilateral dermatome distribution, but may also appear as discrete or multiple skin lesions in random distribution. Blood cultures are frequently positive (40%–50%) when cutaneous lesions appear. XVI. If a necrotizing infection is present, it will be obvious from the findings described above. What is the treatment for infected animal bite–related wounds? Risk Factors for Surgical Site Infection in Minor Dermatological Surgery: A Systematic Review. Clean wounds show no signs of infection or inflammation and do not involve repairing or removing an internal organ. One small study, however, found that packing caused more pain and did not improve healing when compared to just covering the incision site with sterile gauze [23]. What is the appropriate approach for the evaluation and treatment of bacillary angiomatosis and cat scratch disease? Blood cultures are positive in 5%–30% of patients. Extranodal disease (eg, central nervous system, liver, spleen, bone, and lung) develops in ≤2% of cases. HSV infections in compromised hosts are almost exclusively due to viral reactivation. Presenting findings are localized pain in a single muscle group, muscle tenderness, and fever. In patients with persistent unexplained fever of their first episode (after 4–7 days) or recurrent fever, yeast and molds are the major cause of infection-related morbidity and mortality (Table 7) [187, 189, 203]. Staphylococcus aureus accounts for about 90% of pathogens causing pyomyositis; community-acquired MRSA isolates in this infection have been reported in many nontropical communities [124–126]. While many patients with a SSI will develop fever, it usually does not occur immediately postoperatively, and in fact, most postoperative fevers are not associated with an SSI [80]. This observation underscores the importance of detecting and treating tinea pedis, erythrasma, and other causes of toe web abnormalities. The expert panel complied with the IDSA policy on conflicts of interest, which requires disclosure of any financial or other interest that might be construed as constituting an actual, potential, or apparent conflict. To evaluate wound practices, observe wound care procedures from start to finish, marking whether practices were appropriate (yes) or not (no) or not observed (n/a). One of several clinical manifestations of anthrax is a cutaneous lesion. Trichosporon beigelii is an uncommon but frequently fatal disseminated fungal infection that often involves the skin [220]. Treatment of NTM infections of the skin and soft tissues requires prolonged combination therapy (duration, 6–12 weeks) that should consist of a macrolide antibiotic (eg, clarithromycin) and a second agent to which the isolate is susceptible. Although most infections occur after primary inoculation at sites of skin disruption or trauma, hematogenous dissemination does occur. Additionally, studies were identified by . Rapidly progressive necrotizing SSTIs may initially be clinically subtle in compromised patients, but MRI scans of the involved area may be helpful in defining the depth of infections. Endogenous pathogens can be largely restricted to S. aureus or streptococcal species such as groups A, B, C, or G, and together these account for the vast majority of SSTIs. Empiric antimicrobial therapy should be initiated immediately in these patients on the basis of their underlying disease, primary immune defect, morphology of skin lesions, use of prior antimicrobial prophylaxis, allergy history, and inherent and local profiles of antimicrobial resistance. Divided into five sections, this new edition covers basics of infection, preoperative medical optimisation, intraoperative and postoperative optimisation, diagnosis of infection, and treatment of periprosthetic joint infection. Low-risk patients have a MASCC score ≥21. American Journal of Health-System Pharmacy 2013; 70(3)195-283. Cryptococcal cellulitis has occurred in recipients of blood, bone marrow, or SOT, although the incidence has dramatically decreased with the prophylactic use of the newer azole agents, particularly fluconazole. 2. What is appropriate for diagnosis and treatment for tularemia? Most patients with necrotizing fasciitis should return to the operating room 24–36 hours after the first debridement and daily thereafter until the surgical team finds no further need for debridement. 1 A surgical site infection (SSI) is any infection that arises within 30 days after an operation in any part of the body where the surgery took place: superficial at the incision site, deep at the incision site or in other organs or spaces opened or manipulated during an operation. Infection adversely affects wound healing and may be the cause of wound dehiscence. In addition, radiographic procedures may be critical in a small subset of patients to determine the level of infection and the presence of gas, abscess, or a necrotizing process. The panel followed a process used in the development of other Infectious Diseases Society of America (IDSA) guidelines, which included a systematic weighting of the strength of recommendation and quality of evidence using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) system (Table 1) [1–4]. Rogers HD, Desciak EB, Marcus RP, et al. In addition to common clinical syndromes, the . Infections following surgical operations on the axilla also have a significant recovery of gram-negative organisms, and those in the perineum have a higher incidence of gram-negative organisms and anaerobes [100, 103, 104]; antibiotic selections should provide coverage for these organisms (Table 3). No single empiric regimen is superior, but all recommended regimens should meet the following criteria: broad-spectrum antimicrobial activity including P. aeruginosa, bactericidal in the absence of circulating neutrophils, and low antibiotic-associated toxicity (Table 7). Guidelines for Treatment of Infections in Primary Care . As it progresses, there is systemic toxicity, often including high temperatures, disorientation, and lethargy. If SMX-TMP or levofloxacin is used, anaerobic coverage with either clindamycin or metronidazole should be added (Table 5). It can also cause systemic infection requiring urgent intervention. For patients in whom vancomycin may not be an option, daptomycin, ceftaroline, or linezolid should be added to the initial empiric regimen. The average age at onset is 50–60 years. MRSA is an unusual cause of typical cellulitis. Should Tetanus Toxoid Be Administered for Animal Bite Wounds? Surgical Wound Healing and Management, Second Edition explores the critical role of surgery in wound bed preparation and management, and provides a sound knowledge of wound mechanisms, physiology, and metabolic control. This variant of necrotizing soft tissue infection involves the scrotum and penis or vulva [121, 122]. Pregnancy is a relative contraindication for use of tetracyclines and fluoroquinolones, whereas SMX-TMP may be safely prescribed except in the third trimester of pregnancy [140, 141, 143, 156–160]. No randomized, controlled trials of therapy of cutaneous anthrax exist. Unfortunately, some patients who may benefit from therapy may not receive it in a timely fashion and become infected. Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. Due to geographical distribution, this condition is often called tropical pyomyositis, but cases can occur in temperate climates, especially in patients with human immunodeficiency virus (HIV) infection or diabetes mellitus [123]. What is the appropriate approach to assess SSTIs in immunocompromised patients? Glanders is mainly a disease mainly of solipeds (eg, horses and mules). In some patients, cutaneous inflammation and systemic features worsen after initiating therapy, probably because sudden destruction of the pathogens releases potent enzymes that increase local inflammation. Staphylococcus aureus less frequently causes cellulitis, but cases due to this organism are typically associated with an open wound or previous penetrating trauma, including sites of illicit drug injection. IV. Skin lesions can present as papules, nodules, or ulcers, or with the dermatological appearance of ecthyma gangrenosum. Blood cultures should be obtained and cultures of skin biopsy or aspirate considered for patients with malignancy, severe systemic features (such as high fever and hypotension), and unusual predisposing factors, such as immersion injury, animal bites, neutropenia, and severe cell-mediated immunodeficiency [42]. For mild to moderate disease, oral tetracycline (500 mg qid) or doxycycline (100 mg bid) is appropriate. Combined data from specimen cultures, serologic studies [41, 48–51], and other methods (eg, immunohistochemical staining to detect antigens in skin biopsies [51, 52]), suggests that the vast majority of these infections arise from streptococci, often group A, but also from other groups, such as B, C, F, or G. The source of these pathogens is frequently unclear, but in many cases of leg cellulitis, the responsible streptococci reside in macerated, scaly, or fissured interdigital toe spaces [53, 54]. III. Thus clinicians should have a very low threshold to obtain a skin biopsy (Table 6). Primary intention:the wound edges are held together by artificial means, for example steri-strips, sutures, tissue adhesive (clean surgical wounds). At the time the most recent guideline was released, the plan was to update the guideline every five years to ensure the timeliness and appropriateness of the recommendations. Two randomized trials using twice-daily oral penicillin or erythromycin demonstrated a substantial reduction in recurrences among the antibiotic recipients compared to controls [72, 73]. Computed tomography (CT) or magnetic resonance imaging (MRI) may show edema extending along the fascial plane, although the sensitivity and specificity of these imaging studies are ill defined. Patients with infected wounds require early and careful follow-up observation to ensure that the selected medical and surgical treatment regimens have been appropriate and effective (B-III). �Zh M�`/���;k�5�%��> ��P�I��nc��w�&�sJ:�`����}N���B�V��-�� Surgical wound infections may have pus draining from them and can be red, painful or hot to touch. These patients are at increased risk for infection caused by a select group of bacteria, fungi, viruses, protozoa, and helminths, and some of these pathogens have the capacity to cause SSTIs. Clean-contaminated wounds have no signs of infection at the time of surgery Unsuspected growth of F. tularensis can cause laboratory-acquired disease. Regional lymphangitis/lymphadenopathy occurs in about one-third of cases. Examples of keywords used to conduct literature searches were as follows: skin abscess (recurrent and relapsing), dog bites, skin and soft tissue infections, cellulitis, erysipelas, surgical site infections, wounds, staphylococcus, streptococcus, cat bites, tetanus, bite wounds (care and closure), irrigation, amoxicillin, amoxicillin clavulanate, cefuroxime, levofloxacin, moxifloxacin, sulfamethoxazole-trimethoprim, erythromycin, azithromycin. Assess for Risk Factors for Wound Infection a. S. L. G. has received stocks/bonds from Optimer Pharmaceuticals, Cubist Pharmaceuticals, and Cempra Pharmaceuticals has received honoraria from IDSA (Editor, Clinical Infectious Diseases); has served as a consultant to Cempra Pharmaceuticals; and has received grants from the National Institutes of Health. Recipients of allogeneic blood and bone marrow transplants routinely take acyclovir (800 mg bid) or valacyclovir (500 mg bid) during the first year following transplant for the prevention of VZV and HSV reactivation [240]. This guideline is designed to provide guidance in pediatric patients with a primary skin and soft tissue infection (SSTI). Francisella tularensis, while hardy and persistent in nature, is a fastidious, aerobic, gram-negative coccobacillus. Should corticosteroids be used to complement antibiotic treatment of cellulitis? Features suggestive of necrotizing fasciitis include (1) the clinical findings described above; (2) failure of apparently uncomplicated cellulitis to respond to antibiotics after a reasonable trial; (3) profound toxicity; fever, hypotension, or advancement of the SSTI during antibiotic therapy; (4) skin necrosis with easy dissection along the fascia by a blunt instrument; or (5) presence of gas in the soft tissues. Given the prevalence of community-acquired MRSA in the United States [124, 132], vancomycin is recommended for initial empirical therapy. These guidelines are focused on the diagnosis and management of specific patient groups (eg, fever and neutropenia, infection in recipients of hematopoietic stem cell transplant), specific infections (eg, candidiasis, aspergillosis), and iatrogenic infections (eg, intravascular catheter–related infection). Despite clinical responses and appropriate treatment in one study from France, 38.6% of patients relapsed [177]. Providing specific treatment protocols that can be individualized to a particular patient’s condition after consideration of the entire clinical picture, this how-to guide focuses on a variety of challenging and controversial situations ... The optimal duration for treating bubonic plague is unknown, but 10–14 days is probably adequate. Similarly, between 1993 and 2005, annual emergency department visits for SSTIs increased from 1.2 million to 3.4 million patients [7]. How - A broad erythematous tract is sometimes evident along the route of the infection, as it advances proximally in an extremity. There is often a predisposing condition, such as diabetes, arteriosclerotic vascular disease, venous insufficiency with edema, venous stasis or vascular insufficiency, ulcer, or injection drug use. Published Current guidelines for antibiotic prophylaxis of surgical wounds. Infections developing after surgical procedures involving nonsterile areas such as colonic, vaginal, biliary, or respiratory mucosa may be caused by a combination of aerobic and anaerobic bacteria [18, 87, 88, 101]. These infections develop in more surgical patients (8%) than in any other patient group, and about 70% of all nosocomial infections throughout the hospital develop in patients who have an operation. However, there is considerable batch-to-batch variation of IVIG in terms of the quantity of neutralizing antibodies, and clinical data of efficacy are lacking [118]. The lack of evidence-based approaches results in clinical decisions being made based on physicians’ best opinion, or extrapolation from other patient populations. Based on case reports and small series, either erythromycin (500 mg qid) or doxycycline (100 mg bid) appears effective [171]. You will be subject to the destination website's privacy policy when you follow the link. Cephalosporins, clindamycin, or fluoroquinolones should be effective for those intolerant of penicillin. Some of these strains are also clindamycin resistant. It develops in normal soft tissue in the absence of trauma as a result of hematogenous spread from a colonic lesion, usually cancer. Antimicrobial Stewardship Centers of Excellence Program, myIDSA Practice Managers Community Opt-in Form, Fellows-In-Training Career & Education Center, Antimicrobial Stewardship Center of Excellence, Fellows-in-Training Career and Education Center, Practice Guidelines for the Diagnosis and Management of Skin and Soft Tissue Infections: 2014 Update by the Infectious Diseases Society of America, Gram stain and culture of the pus or exudates from skin lesions of impetigo and ecthyma are recommended to help identify whether. The 1985 reissue added new information on preoperative hair removal and surgical ventilation. In addition, Figure 2 is provided to simplify the approach to patients with surgical site infections. Guidelines for Treatment of Skin and Soft Tissue Infections . x Infection x CCHCS Wound Management Team Referral (CCHCS-WMT), as indicated x Vascular Surgery Referral Non-Healing Surgical Wound Present? This practice guideline provides recommendations for the diagnosis and management of skin and soft tissue infections (SSTIs) in otherwise healthy hosts and compromised hosts of all age groups. Consequently, the decision to give “prophylactic” antibiotics should be based on wound severity and host immune competence [147, 148]. Some clinicians close the wound with sutures or pack it with gauze or other absorbent material. This eschar generally separates and sloughs after 12–14 days. Ecthyma gangrenosum has classically been reported to occur with Pseudomonas aeruginosa infections, but similar lesions may be caused by other Pseudomonas species, Aeromonas species, Serratia species, S. aureus, Stenotrophomonas maltophilia, S. pyogenes, fungi including Candida species, Aspergillus, Mucor, and Fusarium, and even herpes simplex virus (HSV) [201]. The efficacy of intravenous immunoglobulin (IVIG) in treating streptococcal toxic shock syndrome has not been definitively established. VI. For adults, the regimen for streptomycin is 30 mg/kg/day in 2 divided doses (no more than 2 g daily) or gentamicin 1.5 mg/kg every 8 hours, with appropriate dose adjustment based on renal function. Necrotizing fasciitis and/or streptococcal toxic shock syndrome caused by group A streptococci should be treated with both clindamycin and penicillin.
