Abstract
Necrotizing fasciitis is a severe, life-threatening disease with a nonspecific clinical presentation, making it a challenging diagnosis. Early treatment with broad-spectrum antibiotics and surgical debridement is crucial to prevent rapid disease progression and poor outcomes. Given its high mortality rate and ambiguous presentation, maintaining a high index of suspicion for necrotizing fasciitis is essential. In this case, a 60-year-old woman presented to her gynecologist with urinary tract infection symptoms of frequency, hematuria, and suprapubic pain, with a year-long history of night sweats, hematuria, dysuria, and incomplete voiding. Although initially treated with outpatient antibiotics, she returned to the emergency department one day later with severe lower abdominal pain, overlying erythema, and a high fever. Abdominal imaging revealed extensive cellulitis. Upon the development of rapidly expanding erythema and crepitus, there was concern for necrotizing fasciitis. The patient received immediate treatment with broad-spectrum antibiotics and underwent urgent surgical debridement. While she showed clinical improvement in the following days, laboratory studies revealed profound hypercalcemia, anemia, and persistent leukocytosis. Additional testing ultimately led to the diagnosis of advanced bladder cancer. This case underscores the importance of prompt recognition and treatment of necrotizing fasciitis. It also highlights the influence of confirmation and availability biases, which can lead to overlooking symptoms that may indicate more serious underlying conditions. As medical professionals, it is crucial to remain vigilant and not disregard seemingly insignificant symptoms, as they could be indicative of life-threatening diagnoses.

Abstract
A 48-year-old male, known to have hypertension (HTN), ischemic heart disease (IHD) post-percutaneous coronary intervention (PCI) before one year, and morbid obesity (BMI: 60), presented to the emergency department complaining of right thigh pain and swelling that started two days before. The swelling got increasingly worsen over the previous days, associated with dyspnea, for which he sought medical attention in another hospital. He was found to have a picture of sepsis where they offered him irrigation and debridement (I&D) but he refused and presented to our institution in a hemodynamically unstable condition. The patient underwent immediate surgery with subsequent intensive care unit (ICU) admission as a case of necrotizing fasciitis complicated by sepsis. Later he was found to have coronavirus disease 2019 (COVID-19) infection.

Abstract
MiraDry® is a microwave-based cosmetic device commonly used to treat hyperhidrosis and osmidrosis by affecting apocrine and eccrine sweat glands. In most countries, its application is limited to the axillary region. A healthy woman received MiraDry® treatment in the perineal, genital, and perianal regions for body odor in a cosmetic clinic. She experienced severe adverse effects after treatment, including persistent fever, sustained pain, and bleeding in the treated area. The condition deteriorated rapidly with systemic symptoms, and she died on the sixth day. Group A Streptococcus was detected in her skin in the treated areas, and in blood obtained in the hospital and during autopsy. Combined with the clinical diagnosis and autopsy findings, the woman's death was attributed to fatal necrotizing fasciitis (Fournier's gangrene) complicated by streptococcal toxic shock syndrome. Pathogen inoculation was most likely attributable to skin disruption caused by MiraDry® treatment. The MiraDry® application on the genital and perineum is occasionally performed by cosmetic surgeons; however, this case demonstrates the possibility of a rare but fatal complication. Therefore, this case report may be noteworthy and beneficial in forensic practice, and relevant in cosmetic clinical practice.

Abstract
Streptococcal toxic shock syndrome (STSS) caused by group A streptococcus is a rare condition that rapidly developed to multiple organ failure even death. Therefore, prompt diagnosis, initiate appropriate antibiotics and other supportive treatments are critical. Here we reported a case of STSS caused by group A streptococcus infection. A healthy 39-year-old man presented a sudden pain in the left lower extremity, followed by a high fever (40.0 °C) with dizziness, nausea, and shortness of breath. Twenty-four hours before the visit, the patient showed anuria. The patient was then admitted to the intensive care unit. Blood examination revealed elevated levels of inflammatory markers and creatinine. He suffered from septic shock, dysfunction of coagulation, acute kidney dysfunction, acute respiratory distress syndrome, and acute liver function injury. The diagnosis was obtained through clinical manifestation and metagenomic next-generation sequencing (mNGS) drawn from the pustule and deep soft tissue (lower limb) samples while all bacterial cultures came back negative. The pustule mNGS report detected a total of 132 unique group A streptococcus sequence reads, representing 96.3% of microbial reads while the soft tissue mNGS report identified a total of 142474 unique group A streptococcus sequence reads, representing 100% of microbial reads. The patient was treated with aggressive fluid resuscitation, antibiotics comprising piperacillin/tazobactam and clindamycin, respiratory support, following the delayed surgical debridement. Intravenous immunoglobulin was also used for 5 days. On the 14th day after admission, he was transferred to the general ward for follow-up treatment. Our case highlighted, for the first time, the key role of mNGS in the early diagnosis of culture-negative invasive group A streptococcal infection. The case also suggested that clindamycin combined with beta-lactam antibiotics and adjunction of intravenous immunoglobulin therapy with delayed debridement performed well in the management of unstable STSS patients.

Abstract
Background: Necrotizing fasciitis (NF) is a severe, potentially life-threatening condition. The aim of this study is to identify strategies aimed at reducing complications in patients with NF of the upper limb. Methods: We conducted a retrospective study on patients admitted to our Unit for suspected NF of the upper limb. The analyzed data included patient characteristics, delay before primary care, clinical and biological signs upon arrival, pathogens involved, and the rate of amputations and mortality. Results: A total of 21 patients presented with confirmed necrotizing bacterial dermohypodermitis-NBDH with NF (NBDH-NF) affecting the upper limb. The mean delay between the onset of symptoms and the clinical examination in the Emergency Dermatology Unit was 48 h (range: 6 to 72 h). The mean delay between admission and primary surgery was 150 min (range: 60 min to 280 min). No amputations were performed. All patients were alive one year after the first surgical procedure. Conclusions: Our study demonstrated that it is possible to reduce mortality and morbidity rates in NF of the upper limb. Timely diagnosis and early treatment and a multidisciplinary medico-surgical dedicated team providing care can significantly modify the outcomes. Early surgical debridement is the most important factor affecting the prognosis of these infections.

Abstract
BACKGROUND Necrotizing soft tissue infection (NSTI) is a life-threatening infection associated with high morbidity and mortality. Treatment consists of surgery and antibiotics. Many studies have addressed NSTI and its subtypes, but few have reviewed the clinical, radiological, and pathological differences between the polymicrobial and monomicrobial diseases. The objective of our study was to evaluate the clinical, radiological, and pathological features of patients with polymicrobial (NSTI I) and monomicrobial (NSTI II) infections and their association with outcome. METHODS The cohort consisted of patients hospitalized with NSTI at a tertiary medical center in 2002-2019. The medical charts were reviewed for clinical, radiological, and pathological features. Findings were compared between patients in whom blood/tissue bacterial cultures yielded one or more than one pathological isolate. The primary clinical outcome measure of the study was all-cause mortality at 90 days. Secondary outcomes were duration of hospitalization, intensive care unit (ICU) admission, score on the LRINEC (Laboratory Risk Indicator for Necrotizing Fasciitis), and need for vasopressor treatment. RESULTS A total of 81 patients met the inclusion criteria: 54 (66.6%) with monomicrobial NSTI and 27 (33.3%) with polymicrobial NSTI. There were no significant between-group differences in in-hospital and 90-day mortality. On multivariate analysis, the monomicrobial disease group had a significantly higher 90-day mortality rate in addition to higher rates of in-hospital mortality, ICU admission, and vasopressor use than the polymicrobial disease group. CONCLUSION Our study is the first to compare the clinical, radiological, and pathological differences between the two most common types of NSTI. The results demonstrate better prognosis for polymicrobial NSTI, with minimal ICU stay, lower mortality, and lower use of vasopressors. LEVEL OF EVIDENCE Prognostic and epidemiological, level III.

Abstract
BACKGROUND Necrotizing soft-tissue infections (NSTI) are life-threatening conditions often caused by β-hemolytic streptococci, group A Streptococcus (GAS) in particular. Optimal treatment is contentious. The INFECT cohort includes the largest set of prospectively enrolled streptococcal NSTI cases to date. METHODS From the INFECT cohort of 409 adults admitted with NSTI to 5 clinical centers in Scandinavia, patients culture-positive for GAS or Streptococcus dysgalactiae (SD) were selected. Risk factors were identified by comparison with a cohort of nonnecrotizing streptococcal cellulitis. The impact of baseline factors and treatment on 90-day mortality was explored using Lasso regression. Whole-genome sequencing of bacterial isolates was used for emm typing and virulence gene profiling. RESULTS The 126 GAS NSTI cases and 27 cases caused by SD constituted 31% and 7% of the whole NSTI cohort, respectively. When comparing to nonnecrotizing streptococcal cellulitis, streptococcal NSTI was associated to blunt trauma, absence of preexisting skin lesions, and a lower body mass index. Septic shock was significantly more frequent in GAS (65%) compared to SD (41%) and polymicrobial, nonstreptococcal NSTI (46%). Age, male sex, septic shock, and no administration of intravenous immunoglobulin (IVIG) were among factors associated with 90-day mortality. Predominant emm types were emm1, emm3, and emm28 in GAS and stG62647 in SD. CONCLUSIONS Streptococcal NSTI was associated with several risk factors, including blunt trauma. Septic shock was more frequent in NSTI caused by GAS than in cases due to SD. Factors associated with mortality in GAS NSTI included age, septic shock, and no administration of IVIG.

Abstract
Introduction Pyogenic β-hemolytic streptococci (including Group A, C and G Streptococcus) are some of the most important Gram-positive bacterial pathogens in human medicine. Although effective therapy is available, invasive streptococcal infections are associated with a significant disease burden. Methods In this retrospective study, the epidemiological characteristics of invasive Group A (iGAS) and Group C and G (iGCGS) streptococci, along with tonsillo-pharyngitis-causing pGAS and pGCGS infections, were assessed in Southern Hungary. A total of 1554 cases of streptococcal tonsillo-pharyngitis infections (26.5–44.1/100,000 persons, pGAS: 95.5%; n=1484) and 1104 cases of invasive streptococcal infections were detected (12.5–31.4/100,000 persons, iGAS: 77.9%; n=861). Results The average age of the affected patients in the various groups were the following: pGAS: 13.2±13.1 years, pGCGS: 21.0±15.0 years (p=0.039), iGAS: 49.1±12.8 years, iGCGS: 58.7±18.5 years (p>0.05). iGAS isolates originated from abscesses (47.1%), blood culture samples (24.1%), surgical samples (16.7%), biopsies (4.6%), pleural fluid (3.5%), pus (2.0%), synovial fluid (1.3%) and cerebrospinal fluid samples (0.7%). In contrast, iGCGS isolates mainly originated from blood culture samples (53.8%), abscesses (22.9%), surgical samples (12.3%), synovial fluid (5.1%), pleural fluid (3.7%), pus (1.8%) and cerebrospinal fluid samples (0.4%). All respective isolates were susceptible to benzyl-penicillin; overall resistance levels for erythromycin (10.5% for GAS, 21.4% for GCGS) and clindamycin (9.2% for GAS, 17.2% for GCGS) were significantly higher in GCGS isolates, while resistance levels for norfloxacin were higher in GAS isolates (13.5% for GAS, 6.9% for GCGS). Conclusion The rates of resistance to macrolides and clindamycin are a cause for concern (especially among GCGS isolates); however, resistance levels are still relatively low, compared to Southern European countries.

Abstract
Necrotizing soft tissue infections occur after traumatic injuries, minor skin lesions, nonpenetrating injuries, natural childbirth, and in postsurgical and immunocompromised patients. Infections can be severe, rapidly progressive, and life threatening. Survivors often endure multiple surgeries and prolonged hospitalization and rehabilitation. Despite subtle nuances that may distinguish one entity from another, clinical approaches to diagnosis and treatment are highly similar. This review describes the clinical and laboratory features of necrotizing soft tissue infections and addresses recommended diagnostic and treatment modalities. It discusses the impact of delays in surgical debridement, antibiotic use, and resuscitation on mortality, and summarizes key pathogenic mechanisms.

Abstract
INTRODUCTION Many similarities exist between the care of necrotising fasciitis (NF) and burn injury patients. Each group represents a small but complex cohort requiring multiple theatre trips, specialist reconstruction, meticulous wound care and multidisciplinary management. Over a six-year period, we sought to examine the clinical outcomes of NF patients managed within a burns centre against those managed by a plastic surgery service. METHODS A retrospective case-note review was performed for all identifiable patients referred to our institution's designated burns centre or plastic surgery service between 2008-2014. Patient characteristics, length of stay, wound-related and clinical outcomes were extracted and descriptively presented with statistical analysis performed for survival and length of stay. RESULTS Twenty-nine patients were included in the study (burns centre [B]: 17 patients; plastic surgery service [P]: 12 patients). Median total length of stay (B: 37 vs. P: 50 days, P=0.38), local length of stay (27 vs. 19 days, P=0.29) and survival till discharge (94.4% vs. 100%, P=0.73) demonstrated no statistically significant difference. CONCLUSION Caring for NF patients within a burns centre facilitated easier access to specialist reconstructive expertise and multidisciplinary care but did not lead to statistically significant differences in length of stay or survival. The management of NF within a burns centre facilitated provision of high-quality care to a highly challenging patient group.

Abstract
β-hemolytic streptococci are major causes of necrotizing soft tissue infections (NSTIs), Streptococcus pyogenes (group A streptococcus; GAS) in particular. NSTIs caused by Streptococcus dysgalactiae (SD) have also been reported. In the INFECT cohort of 409 NSTIs patients, more than a third of the cases were caused by GAS (31%) or SD (7%). Risk factors of streptococcal NSTIs compared to streptococcal cellulitis have previously been largely unknown. The INFECT study confirmed blunt trauma as an important risk factor. In addition, absence of pre-existing skin lesions and a lower BMI were associated with NSTIs. The study also confirmed that septic shock is more frequent in GAS cases than in other types of NSTIs. Septic shock was also among several predictors of mortality. The role of intravenous immunoglobulin (IVIG) in streptococcal NSTIs has been unclear. In the INFECT cohort, IVIG treatment was associated with increased survival. As in other studies, a significant microbial diversity was observed, but with predominance of a few emm types. Overall, the INFECT study gives a comprehensive and contemporary picture of the clinical characteristics and the microbes involved in streptococcal NSTIs. The reported severity of disease underscores the need for new efforts aimed at identifying novel diagnostic measures and improved treatment.

Necrotizing fasciitis following measles vaccine administration: a case report. BMC Infect Dis 2019; 19:524. [PMID: 31200657 PMCID: PMC6570831 DOI: 10.1186/s12879-019-4158-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2018] [Accepted: 06/04/2019] [Indexed: 12/05/2022] Open
Abstract
Background The occurrence of adverse events following immunization (AEFI) in national immunization programmes is very rare; however, if they occur causality assessment is conducted to identify the associated cause. In the report, we describe a case of severe necrotizing fasciitis in the left arm of a 9-month old boy following administration of the measles vaccine. Case presentation A 9-month old boy presented with swelling on the left upper arm and adjoining the chest area, low-grade continuous fever, frequent passage of loose watery stool and persistent cries 24 h after measles vaccine was administered on the left upper arm. On examination, he was mildly pale, febrile, anicteric. Extensive erythema of the left upper arm occurred thereafter with extensive scalded skin lesions involving the deltoid area, the upper chest wall and arm. This was followed by desquamation of the affected areas and severe necrosis. A diagnosis of severe necrotizing fasciitis was made. A causality assessment was conducted by the state AEFI committee using the detailed AEFI investigation forms to identify the cause of the incidence. Conclusion Here we present a rare case of necrotizing fasciitis which could have been caused by incorrect use of reconstituted measles vaccine. Hence we recommend training of routine immunization service providers on proper vaccine management as well as intensified supervision of immunization sessions.

Abstract
BACKGROUND Necrotizing soft tissue infections (NSTI) are rare, life-threatening, soft-tissue infections characterized by rapidly spreading inflammation and necrosis of the skin, subcutaneous fat, and fascia. While it is widely accepted that delay in surgical debridement contributes to increased mortality, there are currently no practice management guidelines regarding the optimal timing of surgical management of this condition. Although debridement within 24 hours of diagnosis is generally recommended, the time ranges from 3 hours to 36 hours in the existing literature. Therefore, the objective of this article is to provide evidence-based recommendations for the optimal timing of surgical management of NSTI. METHODS The MEDLINE database using PubMed was searched to identify English language articles published from January 1990 to September 2015 regarding adult and pediatric patients with NSTIs. A systematic review of the literature was performed, and the Grading of Recommendations Assessment, Development and Evaluation framework were used. A single population [P], intervention [I], comparator [C], and outcome [O] (PICO) question was applied: In patients with NSTI (P), should early (<12 hours) initial debridement (I) versus late (≥12 hours) initial debridement (C) be performed to decrease mortality (O)? RESULTS Two hundred eighty-seven articles were identified. Of these, 42 papers underwent full text review and 6 were selected for guideline construction. A total of 341 patients underwent debridement for NSTI. Of these, 143 patients were managed with early versus 198 with late operative debridement. Across all studies, there was an overall mortality rate of 14% in the early group versus 25.8% in the late group. CONCLUSION For NSTIs, we recommend early operative debridement within 12 hours of suspected diagnosis. Institutional and regional systems should be optimized to facilitate prompt surgical evaluation and debridement. LEVEL OF EVIDENCE Systematic review/meta-analysis, level IV.

Predicting Morbidity and Mortality in Patients with Lower Extremity Necrotizing Fasciitis. MEDICAL BULLETIN OF SISLI ETFAL HOSPITAL 2019; 53:27-32. [PMID: 33536822 PMCID: PMC7847728 DOI: 10.14744/semb.2019.57778] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/27/2018] [Accepted: 01/28/2019] [Indexed: 11/20/2022]
Abstract
Objectives: Necrotizing fasciitis (NF) is a rare but limb- and life-threatening soft-tissue infection. It is among the most challenging surgical infections faced by surgeons, and is often accompanied by severe systemic toxicity. The aim of this study was to evaluate the predictive power of serum lactate and creatinine levels for mortality and morbidity in lower extremity NF. Methods: A retrospective cohort analysis of 87 patients with lower extremity NF was performed to evaluate the management techniques and the amputation and survival rates according to serum lactate and creatinine levels as well as the time between the onset of symptoms and surgery. Results: The mean time between the onset of symptoms and surgery was 3.7 days. As the time between the onset of symptoms and surgery increased, the rate of amputation and mortality significantly increased (p<0.001). In all, 66% of the mortality in the group was seen among the 12 patients who had a serum creatinine level greater than 2 mg/dL at the time of presentation. In 12 of 14 patients (85.7%) who underwent amputation/disarticulation, the mean serum lactate level was 5.7 mmol/L (range: 5.1-8.7 mmol/L), and the mean serum creatinine level was 1.92 mg/dL (range: 1.4 to.3.3 mg/dL). The high levels of serum creatinine and lactate were found to be statistically significant in terms of predicting mortality and amputation (p<0.001). Conclusion: Based on the results of this study, it was determined that risk factors for mortality include age, late presentation, increased serum creatinine and lactate levels, and that these factors can predict the rate of death from NF at the time of presentation.

Abstract
BACKGROUND Necrotizing soft tissue infections (NSTIs) are severe and rapidly spreading soft tissue infections of the subcutaneous tissue, fascia, or muscle, which are mostly caused by bacteria. Associated rates of mortality and morbidity are high, with the former estimated at around 23%, and disability, sequelae, and limb loss occurring in 15% of patients. Standard management includes intravenous empiric antimicrobial therapy, early surgical debridement of necrotic tissues, intensive care support, and adjuvant therapies such as intravenous immunoglobulin (IVIG). OBJECTIVES To assess the effects of medical and surgical treatments for necrotizing soft tissue infections (NSTIs) in adults in hospital settings. SEARCH METHODS We searched the following databases up to April 2018: the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trials registers, pharmaceutical company trial results databases, and the US Food and Drug Administration and the European Medicines Agency websites. We checked the reference lists of included studies and reviews for further references to relevant randomised controlled trials (RCTs). SELECTION CRITERIA RCTs conducted in hospital settings, that evaluated any medical or surgical treatment for adults with NSTI were eligible for inclusion. Eligible medical treatments included 1) comparisons between different antimicrobials or with placebo; 2) adjuvant therapies such as intravenous immunoglobulin (IGIV) therapy compared with placebo; no treatment; or other adjuvant therapies. Eligible surgical treatments included surgical debridement compared with amputation, immediate versus delayed intervention, or comparisons of number of interventions.RCTs of hyperbaric oxygen (HBO) therapy for NSTI were ineligible because HBO is the focus of another Cochrane Review. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. The primary outcome measures were 1) mortality within 30 days, and 2) proportion of participants who experience a serious adverse event. Secondary outcomes were 1) survival time, and 2) assessment of long-term morbidity. We used GRADE to assess the quality of the evidence for each outcome. MAIN RESULTS We included three trials randomising 197 participants (62% men) who had a mean age of 55 years. One trial compared two antibiotic treatments, and two trials compared adjuvant therapies with placebo. In all trials, participants concomitantly received standard interventions, such as intravenous empiric antimicrobial therapy, surgical debridement of necrotic tissues, intensive care support, and adjuvant therapies. All trials were at risk of attrition bias and one trial was not blinded.Moxifloxacin versus amoxicillin-clavulanate One trial included 54 participants who had a NSTI; it compared a third-generation quinolone, moxifloxacin, at a dose of 400 mg given once daily, against a penicillin, amoxicillin-clavulanate, at a dose of 3 g given three times daily for at least three days, followed by 1.5 g three times daily. Duration of treatment varied from 7 to 21 days. We are uncertain of the effects of these treatments on mortality within 30 days (risk ratio (RR) 3.00, 95% confidence interval (CI) 0.39 to 23.07) and serious adverse events at 28 days (RR 0.63, 95% CI 0.30 to 1.31) because the quality of the evidence is very low.AB103 versus placebo One trial of 43 randomised participants compared two doses, 0.5 mg/kg and 0.25 mg/kg, of an adjuvant drug, a CD28 antagonist receptor (AB103), with placebo. Treatment was given via infusion pump for 10 minutes before, after, or during surgery within six hours after the diagnosis of NSTI. We are uncertain of the effects of AB103 on mortality rate within 30 days (RR of 0.34, 95% CI 0.05 to 2.16) and serious adverse events measured at 28 days (RR 1.49, 95% CI 0.52 to 4.27) because the quality of the evidence is very low.Intravenous immunoglobulin (IVIG) versus placebo One trial of 100 randomised participants assessed IVIG as an adjuvant drug, given at a dose of 25 g/day, compared with placebo, given for three consecutive days. There may be no clear difference between IVIG and placebo in terms of mortality within 30 days (RR 1.17, 95% CI 0.42 to 3.23) (low-certainty evidence), nor serious adverse events experienced in the intensive care unit (ICU) (RR 0.73 CI 95% 0.32 to 1.65) (low-certainty evidence).Serious adverse events were only described in one RCT (the IVIG versus placebo trial) and included acute kidney injury, allergic reactions, aseptic meningitis syndrome, haemolytic anaemia, thrombi, and transmissible agents.Only one trial reported assessment of long-term morbidity, but the outcome was not defined in the way we prespecified in our protocol. The trial used the Short Form Health Survey (SF36). Data on survival time were provided upon request for the trials comparing amoxicillin-clavulanate versus moxifloxacin and IVIG versus placebo. However, even with data provided, it was not possible to perform survival analysis. AUTHORS' CONCLUSIONS We found very little evidence on the effects of medical and surgical treatments for NSTI. We cannot draw conclusions regarding the relative effects of any of the interventions on 30-day mortality or serious adverse events due to the very low quality of the evidence.The quality of the evidence is limited by the very small number of trials, the small sample sizes, and the risks of bias in the included trials. It is important for future trials to clearly define their inclusion criteria, which will help with the applicability of future trial results to a real-life population.Management of NSTI participants (critically-ill participants) is complex, involving multiple interventions; thus, observational studies and prospective registries might be a better foundation for future research, which should assess empiric antimicrobial therapy, as well as surgical debridement, along with the placebo-controlled comparison of adjuvant therapy. Key outcomes to assess include mortality (in the acute phase of the condition) and long-term functional outcomes, e.g. quality of life (in the chronic phase).

Abstract
BACKGROUND Soft-tissue infections vary widely in their nature and severity. A clear approach to the management must allow their rapid identification and treatment as they can be life-threatening. OBJECTIVE Clinical presentation of soft-tissue infections and its management. MATERIALS AND METHODS A prospective study based on 100 patients presenting with soft-tissue infections was done. All the cases of soft-tissue infections were considered irrespective of age, sex, etiological factors, or systemic disorders. The findings were evaluated regarding the pattern of soft-tissue infections in relation to age and sex, clinical presentation, complications, duration of hospital stay, management, and mortality. RESULTS The most commonly involved age group was in the range of 41-60 years with male predominance. Abscess formation (45%) was the most common clinical presentation. Type 2 diabetes mellitus was the most common associated comorbid condition. Staphylococcus aureus was the most common culture isolate obtained. The most common complication seen was renal failure. Patients with surgical site infections had maximum duration of stay in the hospital. About 94% of the cases of soft-tissue infections were managed surgically. Mortality was mostly encountered in the cases of complications of cellulitis. CONCLUSION Skin and soft-tissue infections are among the most common infections encountered by the emergency physicians. Ignorance, reluctance to treatment, economic constraints, and illiteracy delay the early detection and the initiation of proper treatment. Adequate and timely surgical intervention in most of the cases is of utmost importance to prevent the complications and reduce the mortality.

Abstract
Acute cutaneous necrosis is characterised by a wide range of aetiologies and is associated with significant morbidity and mortality, warranting complex considerations in management. Early recognition is imperative in diagnosis and management of sudden gangrenous changes in the skin. This review discusses major causes of cutaneous necrosis, examines the need for early assessment, and integrates techniques related to diagnosis and management. The literature, available via PubMed, on acute cutaneous necrotic syndromes was reviewed to summarise causes and synthesise appropriate treatment strategies to create a clinician’s guide in the early diagnosis and management of acute cutaneous necrosis. Highlighted in this article are key features associated with common causes of acute cutaneous necrosis: warfarin-induced skin necrosis, heparin-induced skin necrosis, calciphylaxis, pyoderma gangrenosum, embolic phenomena, purpura fulminans, brown recluse spider bite, necrotising fasciitis, ecthyma gangrenosum, antiphospholipid syndrome, hypergammaglobulinemia, and cryoglobulinemia. This review serves to increase recognition of these serious pathologies and complications, allowing for prompt diagnosis and swift limb- or life-saving management.

Abstract
Necrotizing soft tissue infections (NSTI) have been recognized for millennia and continue to impose considerable burden on both patient and society in terms of morbidity, death, and the allocation of resources. With improvements in the delivery of critical care, outcomes have improved, although disease-specific therapies are lacking. The basic principles of early diagnosis, of prompt and broad antimicrobial therapy, and of aggressive debridement have remained unchanged. Clearly novel and new therapeutics are needed to combat this persistently lethal disease. This review emphasizes the pillars of NSTI management and then summarizes the contemporary evidence supporting the incorporation of novel adjuncts to the pharmacologic and operative foundations of managing this disease.

Abstract
BACKGROUND Streptococcus equi subsp. zooepidemicus is a beta-hemolytic group C streptococcus mainly causing infections in domesticated animals. Here we describe the first case of zoonotic necrotizing myositis caused by this bacterium. CASE PRESENTATION The patient was a 73-year-old, previously healthy farmer with two asymptomatic Shetland ponies in his stable. After close contact with the ponies while feeding them, he rapidly developed erythema of his left thigh and sepsis with multiple organ failure. The clinical course was severe and complicated, requiring repetitive surgical excision of necrotic muscle, treatment with vasopressors, mechanical ventilation and continuous venovenous hemofiltration, along with adjunctive hyperbaric oxygen therapy. The patient was discharged from hospital at day 30, without obvious sequelae. The streptococcal isolate was identified as Streptococcus equi by MALDI-ToF MS, and was later assigned subspecies identification as S. equi subsp. zooepidemicus. Multilocus sequence typing identified the strain as a novel sequence type (ST 364), closely related to types previously identified in horses and cattle. A focused proteomic analysis revealed that the ST 364 expressed putative virulence factors similar to that of Streptococcus pyogenes, including homologues of the M protein, streptodornases, interleukin 8-protease and proteins involved in the biosynthesis of streptolysin S. CONCLUSION This case illustrates the zoonotic potential of S. equi subsp. zooepidemicus and the importance of early clinical recognition, rapid and radical surgical therapy, appropriate antibiotics and adequate supportive measures when necrotizing soft tissue infection is suspected. The expression of Streptococcus pyogenes-like putative virulence determinants in ST 364 might partially explain the fulminant clinical picture.

Abstract
Rituximab has considerably modified thetherapeutic strategy for B-cell lymphoproliferative malignancies, most notably non-Hodgkin’s lymphoma (NHL). Rituximab, alone or in combination with chemo-therapy, is being used to treat NHL with limited toxicity. We report two cases, one fatal, of necrotizing fasciitis following the use of rituximab in patients with NHL. No obvious predisposing factors were noted in either case. Practitioners need to beaware of this rare side effect and take prompt and aggressive action at the first onset of symptoms.

Abstract
Necrotizing fasciitis is a rapidly progressing bacterial infection of the superficial fascia and subcutaneous tissue that is associated with a high mortality rate and is caused by a single species of bacteria or polymicrobial organisms. Escherichia coli is rarely isolated from patients with monomicrobial disease. Further, there are few reports of extended-spectrum beta-lactamase (ESBL)-producing E. coli associated with necrotizing fasciitis. We report here our treatment of an 85-year-old man who was admitted because of necrotizing fasciitis of his right thigh. Streptococcus equisimilis was detected as a monomicrobial pathogen, and the infection was cured by amputation of the patient's right leg and the administration of antibiotics. However, 5 days after discontinuing antibiotic therapy, he developed necrotizing fasciitis on his right upper limb and died. ESBL-producing E. coli was the only bacterial species isolated from blood and skin cultures. This case demonstrates that ESBL-producing E. coli can cause monomicrobial necrotizing fasciitis, particularly during hospitalization and that a different bacterial species can cause disease shortly after a previous episode.

Abstract
Pyoderma gangrenosum received this name due to the notion that this disease was related to infections caused by bacteria in the genus Streptococcus. In contrast to this initial assumption, today the disease is thought to have an autoimmune origin. Necrotizing fasciitis was first mentioned around the fifth century AD, being referred to as a complication of erysipelas. It is a disease characterized by severe, rapidly progressing soft tissue infection, which causes necrosis of the subcutaneous tissue and the fascia. On the third day of hospitalization after antecubital venipuncture, a 59-year-old woman presented an erythematous and painful pustular lesion that quickly evolved into extensive ulceration circumvented by an erythematous halo and accompanied by toxemia. One of the proposed etiologies was necrotizing fasciitis. The microbiological results were all negative, while the histopathological analysis showed epidermal necrosis and inflammatory infiltrate composed predominantly of dermal neutrophils. Pyoderma gangrenosum was considered as a diagnosis. After 30 days, the patient was discharged with oral prednisone (60 mg/day), and the patient had complete healing of the initial injury in less than two months. This case was an unexpected event in the course of the hospitalization which was diagnosed as pyoderma gangrenosum associated with myelodysplastic syndrome.

Abstract
BACKGROUND Broad-spectrum antibiotic therapy is critical in the management of necrotizing soft tissue infections (NSTI) in the emergency setting. Clindamycin often is included empirically to cover monomicrobial gram-positive pathogens but probably is of little value for polymicrobial infections and is associated with significant side effects, including the induction of Clostridium difficile colitis. However, there have been no studies predicting monomicrobial infections prior to obtaining cultures. The purpose of this study was to identify independent predictors of monomicrobial NSTI where the use of clindamycin would be most beneficial. We hypothesized that monomicrobial infections are characterized by involvement of the upper extremities and fewer co-morbid diseases. METHODS We reviewed all cases of potential NSTI occurring between 1996 and 2013 in a single tertiary-care center. The infection was diagnosed by the finding of rapidly progressing necrotic fascia during debridement with positive cultures of tissue. Univariable analysis was performed using the Student t-, Wilcoxon rank sum, χ2, and Fisher exact tests as appropriate. Multivariable logistic regression was used to identify independent variables associated with outcomes. RESULTS A group of 151 patients with confirmed NSTI with complete data was used. Of the monomicrobial infections, 61.8% were caused by Group A streptococci, 20.1% by Staphylococcus aureus, and 12.7% by Escherichia coli. Of the polymicrobial infections, E. coli was involved 13.7% of the time, followed by Candida spp. at 12.9%, and Bacteroides fragilis at 11.3%. On univariable analysis, immunosuppression, upper extremity infection, and elevated serum sodium concentration were associated with monomicrobial infection, whereas morbid obesity and a perineal infection site were associated with polymicrobial infection. On multivariable analysis, the strongest predictor of monomicrobial infection was immunosuppression (odds ratio [OR] 7.0; 95% confidence interval [CI] 2.2-22.3) followed by initial serum sodium concentration (OR 1.1; 95% CI 1.0-1.2). Morbid obesity (OR 0.1; 95% CI 0.0-0.5) and perineal infection (OR 0.3; 95% CI 0.1-0.8) were independently associated with polymicrobial infection. CONCLUSION We identified independent risk factors that may be helpful in differentiating monomicrobial from polymicrobial NSTI. We suggest empiric clindamycin coverage be limited to patients who are immunosuppressed, have an elevated serum sodium concentration, or have upper extremity involvement and be avoided in obese patients or those with perineal disease.

Abstract
Infections in the neck layers and spaces are potentially life-threatening diseases causing further complications, like mediastinitis, airway obstruction, or sepsis. Despite of the need for a conservative approach, they still regularly require surgical intervention. Records of 17 patients with severe neck infections that were treated by wide external incision and open wound management were retrospectively analyzed. The aim of the study was to clinically characterize these most serious neck infections. The most common presenting symptoms were neck pain and tense neck mass (94-94%) regularly with fever (65%), always accompanied by a marked elevation of C reactive protein level (average 192 uG/l). These findings were constant and very similar among both the deep neck infection and necrotizing fasciitis cases. More than half of the patients (53%) had at least one systemic co-morbidity. The parapharyngeal space was most commonly affected (83%), but extended disease involving more than two major neck regions was found in 13 cases (76%). Dental (29%) was the most common primary infection, followed by peritonsillar abscess (23%), Microbiological results showed a wide variety of corresponding bacteria. Mediastinitis was developed in three cases (18%), and airway obstruction requiring tracheostomy in two cases (12%). All the patients survived. Severe neck infections are a heterogenous group of diseases regarding to the primary site of infection, microbiology, localisation and host reaction. However, rapidly developed, painful, tense neck mass with a highly elevated CRP level should always alert for an extended or phlegmonous process in the layers or spaces of the neck.

Abstract
Pyogenic streptococci cause significant morbidity and mortality, and the incidence of invasive group C and G streptococcal disease appears to be increasing. In this retrospective study we describe the epidemiological characteristics of invasive group A, C and G, along with non-invasive group C and G streptococcal infections in Western Norway from 1999 to 2013. A total of 512 invasive streptococcal infections were identified, of these 297 (58%) were group A (GAS), 24 (5%) group C (GCS) and 188 (37%) group G streptococci (GGS). In the non-invasive group, 4935 GCS and GGS-infections were identified. GCS and GGS were treated as one group (GCGS) for statistical purposes. All microbial categories displayed increasing incidence with age, seasonal variation and a male predominance. The incidence of invasive GCGS infections increased significantly from 1.4/100,000 inhabitants in 1999 to 6.3/100,000 in 2013 (p <0.001). Conversely, the annual rates of invasive GAS infection exhibited marked fluctuations, ranging from 2.7/100,000 (2000) to 8.3/100,000 (1999), but no significant temporal trends were observed. The incidence of non-invasive GCGS infections decreased significantly during the study period (p <0.001). The most frequently encountered emm-types among the 209 iGAS-isolates analysed were emm1 (24%), emm3 (14%) and emm28 (14%); whereas stG643 (19%), stG485 (15%) and stG6 (13%) were most prevalent among the 122 iGCGS-isolates available for typing. The increasing burden of invasive β-haemolytic streptococcal disease in our community calls for sustained attentiveness to the clinical and molecular aspects of GAS, GCS and GGS infections.

Abstract
A panel of national experts was convened by the Infectious Diseases Society of America (IDSA) to update the 2005 guidelines for the treatment of skin and soft tissue infections (SSTIs). The panel's recommendations were developed to be concordant with the recently published IDSA guidelines for the treatment of methicillin-resistant Staphylococcus aureus infections. The focus of this guideline is the diagnosis and appropriate treatment of diverse SSTIs ranging from minor superficial infections to life-threatening infections such as necrotizing fasciitis. In addition, because of an increasing number of immunocompromised hosts worldwide, the guideline addresses the wide array of SSTIs that occur in this population. These guidelines emphasize the importance of clinical skills in promptly diagnosing SSTIs, identifying the pathogen, and administering effective treatments in a timely fashion.

Abstract
We sequenced the genomes of 3,615 strains of serotype Emm protein 1 (M1) group A Streptococcus to unravel the nature and timing of molecular events contributing to the emergence, dissemination, and genetic diversification of an unusually virulent clone that now causes epidemic human infections worldwide. We discovered that the contemporary epidemic clone emerged in stepwise fashion from a precursor cell that first contained the phage encoding an extracellular DNase virulence factor (streptococcal DNase D2, SdaD2) and subsequently acquired the phage encoding the SpeA1 variant of the streptococcal pyrogenic exotoxin A superantigen. The SpeA2 toxin variant evolved from SpeA1 by a single-nucleotide change in the M1 progenitor strain before acquisition by horizontal gene transfer of a large chromosomal region encoding secreted toxins NAD(+)-glycohydrolase and streptolysin O. Acquisition of this 36-kb region in the early 1980s into just one cell containing the phage-encoded sdaD2 and speA2 genes was the final major molecular event preceding the emergence and rapid intercontinental spread of the contemporary epidemic clone. Thus, we resolve a decades-old controversy about the type and sequence of genomic alterations that produced this explosive epidemic. Analysis of comprehensive, population-based contemporary invasive strains from seven countries identified strong patterns of temporal population structure. Compared with a preepidemic reference strain, the contemporary clone is significantly more virulent in nonhuman primate models of pharyngitis and necrotizing fasciitis. A key finding is that the molecular evolutionary events transpiring in just one bacterial cell ultimately have produced millions of human infections worldwide.

Abstract
Bisphosphonates (BPs), potent inhibitors of osteoclast-mediated bone resorption, play a major role in the management of patients with multiple myeloma (MM). However, in the case of dental infections, they can lead to bisphosphonate related osteonecrosis of the jaw (BRONJ). This process can be worsened by concomitant antineoplastic therapy. Herein, we present a case of a life-threatening necrotizing fasciitis (NF) as a rare and severe complication of BRONJ after three cycles of lenalidomide and dexamethasone in an MM patient treated with corticosteroid therapy and Ibandronate for 5 years. The patient presented swelling on the right part of the neck, difficulty in swallowing and acute pain, so a magnetic resonance of the head and neck region was performed. It revealed the presence of an NF with a massive extension. Due to the large necrotic area and a rapid progression of the infection, the necrotic tissue had to be removed surgically. Furthermore, a specific antimicrobial treatment as well as 12 sessions of hyperbaric oxygen therapy were needed to cure the patient. Herein, we highlight the potential serious adverse events associated with the use of bisphosphonates and antiangiogenetic drugs in patients with MM. Future studies are needed to evaluate the potential synergistic effects of BPs, corticosteroids and antiangiogenetic drugs.

Abstract
A patient in his late 50s who suffered from necrotising fasciitis is described in this case report. The patient first presented at the chest pain unit, where he reported of respiratory distress and showed systemic signs of an infection. Because of progressive skin lesions indicative of necrotising fasciitis on both the lower extremities, the patient was immediately rushed into surgery and was treated at the intensive care unit. Despite receiving immediate treatment, the patient died of this rapidly spreading infectious disease. Because of the fast advance of this disease, we would like to emphasise the importance of early recognition of symptoms.

Abstract
Necrotizing fasciitis usually occurs after dermal injury or through hematogenous spread. To date, few cases have been reported as necrotizing fasciitis of the thigh secondary to rectal perforation in rectal cancer patients. A 66-year-old male complained of pelvic and thigh pain and subsequently developed necrotizing fasciitis in his right thigh. Four years earlier, he had undergone a low anterior resection and radiotherapy due to of rectal cancer. An ulcerative lesion had been observed around the anastomosis site during the colonoscopy that had been performed two months earlier. Pelvic computed tomography and sigmoidoscopy showed rectal perforation and presacral abscess extending to buttock and the right posterior thigh fascia. Thus, the necrotizing fasciitis was believed to have occurred because of ulcer perforation, one of the complications of chronic radiation colitis, at the anastomosis site. When a rectal-cancer patient complains of pelvic and thigh pain, the possibility of a rectal perforation should be considered.

Abstract
Necrotizing soft tissue infections and necrotizing fasciitis are life-threatening infections affecting the hypodermis, muscular fascia, and dermis secondarily. Mortality is high, with an average of 30%. The early diagnosis of necrotizing soft tissue infection is challenging, but is key to successful management of these patients. The mainstay of therapy includes early and wide surgical debridement, antibiotics and supportive care. Adjunctive therapies may have a role, but their effectiveness remains unproven. A review of the literature allows us to highlight this multidisciplinary management.

Abstract
Invasive group A streptococcal infections are uncommon, although serious, infections with high case fatality rates. Periodic resurgences in invasive group A streptococcal infections in industrialized countries have been reported from the 1980s onwards, with current estimates of incidence in these countries of approximately 3–4 per 100000 population. Infants, pregnant women and the elderly are at increased risk of invasive group A streptococcal infection. The group A streptococcus has an array of virulence factors that underpin its invasive capacity and, in approximately 10% of cases, super-antigen toxins produced by the bacteria stimulate a large proportion of T cells, leading to streptococcal toxic shock syndrome. Given the rapid clinical progression, effective management of invasive group A streptococcal infections hinges on early recognition of the disease and prompt initiation of supportive care (often intensive care) together with antibacterial therapy. In cases of toxic shock syndrome, it is often difficult to distinguish between streptococcal and staphylococcal infection before cultures become available and so antibacterial choice must include coverage of both of these organisms. In addition, clindamycin is an important adjunctive antibacterial because of its anti-toxin effects and excellent tissue penetration. Early institution of intravenous immunoglobulin therapy should be considered in cases of toxic shock syndrome and severe invasive infection, including necrotizing fasciitis. Early surgical debridement of necrotic tissue is also an important part of management in cases of necrotizing fasciitis.

Abstract
Necrotizing soft tissue infection, such as necrotizing fasciitis, is a group of highly lethal infections especially when the chest is involved due to increased risk of pulmonary complications. Because aggressive radical debridement of all poorly perfused tissue is required, patients frequently suffer from massive skin defects, which often requires autograft skin grafting or myocutaneous flaps. However, options are limited in patients with limited autograft donor availability, or questionable underlying wound bed viability, such as in scleroderma. Here, we report the case of a 49 year old female with scleroderma who suffered from a necrotizing soft tissue infection of the chest extending to her right upper arm, underwent multiple radical debridements, and reconstruction of the consequent massive chest wall defect with INTEGRA® bilaminar dermal regeneration template. This approach required a thinner skin graft without flaps, allowed for the inherently diseased donor site to heal adequately, and avoided major infections and wound complications. This report highlights an important management option for this challenging disease.

Abstract
The purpose of this study is to determine the effect of the corresponding nucleotides from Streptococcus pyogenes on the has promoter strength in highly encapsulated strain S. equi subsp. zooepidemicus (SEZ) and detect an empowering mutations in SEZ. Eight different strains of SEZ carrying nucleotide mutations in the -73 to -38 region upstream of the has promoter were constructed. The significant activity decrease to 36-1% was observed after the introduction of mutations in the promoter region from -44 to -38 site. The exception was observed in mutation in -49 site when no significant decrease was observed. When nucleotides TTT were used in positions -73 the promoter became weaker, whereas no significant effect was observed after using nucleotides CCC (96%). Unfortunately, introduction of these mutations into chromosome SEZ has no empowering effect. Six strains, which carried nucleotide sequences of different lengths upstream from the transcription start of hasA promoter, were constructed to determine the minimum upstream region required for the maximum transcription efficiency of the has operon. No change of the activity of the has promoter constructs containing as few as 101 nucleotides upstream from the transcription start point was observed.

Abstract
OBJECTIVE The aim of the study is to report a case of multi-focal necrotising fasciitis, review research on this subject to identify common aetiological factors and highlight suggestions to improve management. CONTEXT Necrotising fasciitis is a severe, life-threatening soft tissue infection that typically arises from a single area, usually secondary to a minor penetrating injury. Multi-focal necrotising fasciitis, where there is more than one non-contiguous area of necrosis, is much less commonly reported. There are no guidelines specific to the management of multi-focal necrotising fasciitis, and its under-reporting may lead to missed management opportunities. DESIGN A systematic literature review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. DATA SOURCES A search of MEDLINE, OLD MEDLINE and the Cochrane Collaboration was performed from 1966 to March 2011 using 16 search terms. DATA EXTRACTION All articles were screened for genuine non-contiguous multi-focal necrotising fasciitis. Of the papers that met this criterion, data on patient demographics, likely inciting injury, presentation time-line, microbial agents, sites affected, objective assessment scores, treatment and outcome were extracted. DATA SYNTHESIS A total of 31 studies met our inclusion criteria and 33 individual cases of multi-focal necrotising fasciitis were included in the quantitative analysis. About half (52%) of cases were type II necrotising fasciitis; 42% of cases had identifiable inciting injuries; 21% of cases developed multi-focal lesions non-synchronously, of which 86% were type II. Nearly all (94%) of cases had incomplete objective assessment scores. One case identified inflammatory imaging findings prior to clinical necrosis. CONCLUSIONS Multifocality in necrotising fasciitis is likely to be associated with type II disease. We postulate that validated objective tools will aid necrotising fasciitis management pathways that will identify high-risk groups for multifocality and advise early pre-emptive imaging. We recommend the adoption of regional multi-focal necrotising fasciitis registers.

Abstract
Invasive group A streptococcal (iGAS) disease is endemic in Norway, but data on invasive group C and group G streptococcal (iGCS/GGS) disease are lacking. We investigated the characteristics of iGAS and iGCS/GGS infections in western Norway from March 2006 to February 2009. Clinical information was retrospectively obtained from medical records. GAS and GCS/GGS isolates were emm typed and screened for the presence of 11 superantigen (SAg) genes and the gene encoding streptococcal phospholipase A₂ (SlaA). GCS/GGS isolates were also subjected to PCR with primers targeting speG(dys) . Sixty iGAS and 50 iGCS/GGS cases were identified, corresponding to mean annual incidence rates of 5.0 per 100,000 and 4.1 per 100,000 inhabitants, respectively. Skin and soft tissue infections were the most frequent clinical manifestations of both iGAS and iGCS/GGS disease, and 14 iGAS patients (23%) developed necrotizing fasciitis. The 30-day case fatality rates of iGAS and iGCS/GGS disease were 10% and 2%, respectively. emm1, emm3 and emm28 accounted for 53% of the GAS isolates, and these types were associated with severe clinical outcome. SAg gene and SlaA profiles were conserved within most of the GAS emm types, although five profiles were obtained within isolates of emm28. stG643 was the most prevalent GCS/GGS emm type, and speG(dys) was identified in 73% of the GCS/GGS isolates. Neither GAS SAg genes nor SlaA were detected in GCS/GGS. Our findings indicate a considerable burden of both iGAS and iGCS/GGS disease and a high frequency of necrotizing fasciitis caused by GAS in our community.

Abstract
In order to investigate molecular characteristics of beta-hemolytic streptococcal isolates from western Norway, we analysed the entire emm gene sequences, obtained superantigen gene profiles and determined the prevalence of the gene encoding streptococcal phospholipase A2 (SlaA) of 165 non-invasive and 34 contemporary invasive group A, C and G streptococci (GAS, GCS and GGS). Among the 25 GAS and 26 GCS/GGS emm subtypes identified, only emm3.1 was significantly associated with invasive disease. M protein size variation within GAS and GCS/GGS emm types was frequently identified. Two non-invasive and one invasive GGS possessed emm genes that translated to truncated M proteins as a result of frameshift mutations. Results suggestive of recombinations between emm or emm-like gene segments were found in isolates of emm4 and stG485 types. One non-invasive GGS possessed speC, speG, speH, speI and smeZ, and another non-invasive GGS harboured SlaA. speA and SlaA were over-represented among invasive GAS, probably because they were associated with emm3. speGdys was identified in 83% of invasive and 63% of non-invasive GCS/GGS and correlated with certain emm subtypes. Our results indicate the invasive potential of isolates belonging to emm3, and show substantial emm gene diversity and possible lateral gene transfers in our streptococcal population.

Abstract
Necrotizing soft tissue infection is a severe illness that is associated with significant morbidity and mortality. It is often caused by a wide spectrum of pathogens and is most frequently polymicrobial. Care for patients with necrotizing soft tissue infection requires a team approach with expertise from critical care, surgery, reconstructive surgery, and rehabilitation specialists. The early diagnosis of necrotizing soft tissue infection is challenging, but the keys to successful management of patients with necrotizing soft tissue infection are early recognition and complete surgical debridement. Early initiation of appropriate broad-spectrum antibiotic therapy must take into consideration the potential pathogens. Critical care management components such as the initial fluid resuscitation, end-organ support, pain management, nutrition support, and wound care are all important aspects of the care of patients with necrotizing soft tissue infection. Soft tissue reconstruction should take into account both functional and cosmetic outcome.
