Abstract
Necrotizing fasciitis is a severe, life-threatening soft tissue infection that presents as a surgical emergency. It is characterized by a rapid progression of inflammation leading to extensive tissue necrosis and destruction. Nonetheless, the diagnosis might be missed or delayed due to variable and nonspecific clinical presentation, contributing to high mortality rates. Therefore, early diagnosis and prompt, aggressive medical and surgical treatment are paramount. In this review, we highlight the defining characteristics, pathophysiology, diagnostic modalities, current principles of treatment, and evolving management strategies of necrotizing fasciitis.

Abstract
Necrotizing fasciitis (NF) is a rapidly progressive, life-threatening infection, involving the skin, soft tissue and fascia. We evaluated outcomes of its surgical management in diabetic foot (DF) patients in a tertiary referral centre. We retrospectively searched for NF in the database of our DF Section from 2016 to 2018. All cases were treated according to a multiprofessional integrated protocol, with Prompt Identification, Surgical debridement and systemic Antibiotic therapy (P.I.S.A. Protocol). We analysed short-term evolution (surgical procedures and major amputations), and long-term outcomes (survival and healing rates). Sixty-eight patients were referred to our DF clinic for suspicion of NF. The diagnosis was confirmed in 54 (79.4%; male/female 40/14; type 1/2 diabetes 6/48; age 62.8 ± 8.1 years; duration of diabetes 13.6 ± 10.1 years). According to the microbiological results, cases were classified as Type 1 (33-61.2%), 2 (7-12.9%) and 3 (14-25.9%). No significant differences were observed. All patients underwent a decompressive fasciotomy. Six patients (11.1%) required also a forefoot amputation and 12 (22.2%) a toe or ray amputation. No major amputation was performed in the short-term period. During the follow-up (26 ± 12 months) 46 patients (85%) healed in 94 ± 11 days. Of the remaining 8: 5 (9.2%) died for other reasons before healing, 2 (3.7%) recurred and one (1.9%) required a major amputation. Our experience reveals a relatively high prevalence of NF in DF; despite this, we observed how, when promptly and aggressively treated, NF has a good prognosis and it is not associated with an excess of limb loss and deaths.

Initial skin necrosis presentation at emergency room was associated with fulminant clinical course and mortality in patients with Vibrio necrotizing fasciitis. Sci Rep 2023; 13:18410. [PMID: 37891231 PMCID: PMC10611701 DOI: 10.1038/s41598-023-45854-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Accepted: 10/25/2023] [Indexed: 10/29/2023] Open
Abstract
Necrotizing fasciitis (NF) is a life-threatening infection. Skin necrosis is an important skin sign of NF. The purposes of this study was to investigate the initial skin conditions of Vibrio NF patients between emergency room (ER) to preoperative status, to compare the clinical and laboratory risk indicators of the skin necrosis group and non-skin necrosis group when they arrived at ER, and to evaluate whether initial cutaneous necrosis related to fulminant course and higher fatalities. From 2015 to 2019, seventy-two Vibrio NF patients with surgical confirmation were enrolled. We identified 25 patients for inclusion in the skin necrosis group and 47 patients for inclusion in the non-skin necrosis group due to the appearance of skin lesion at ER. Seven patients died, resulting in a mortality rate of 9.7%. Six patients of skin necrosis group and one patient of non-skin necrosis group died, which revealed the skin necrosis group had a significantly higher mortality rate than the non-skin necrosis group. All the patients in the skin necrosis group and 30 patients of non-skin necrosis group developed serous or hemorrhagic bullous lesions before operation (p = 0.0003). The skin necrosis group had a significantly higher incidence of APACHE score, postoperative intubation, Intensive care unit stay, septic shock, leukopenia, higher counts of banded leukocytes, elevated C-reactive protein (CRP), and lower serum albumin level. Vibrio NF patients presenting skin necrosis at ER were significantly associated with fulminant clinical courses and higher mortality. Physicians should alert the appearance of skin necrosis at ER to early suspect NF and treat aggressively by those clinical and laboratory risk indicators, such as elevated APACHE score, shock, leukopenia, higher banded leukocytes, elevated CRP, and hypoalbuminia.

Is Neutrophil Lymphocyte Ratio, Platelet Lymphocyte Ratio or Red Blood Cell Distribution Width Associated with Risk of Mortality in Patients with Necrotizing Fasciitis. Infect Drug Resist 2023; 16:3861-3870. [PMID: 37346369 PMCID: PMC10281279 DOI: 10.2147/idr.s413126] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2023] [Accepted: 06/07/2023] [Indexed: 06/23/2023] Open
Abstract
Purpose Neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), and red blood cell distribution width (RDW) are novel biomarkers to indicate the inflammatory/immune response, and demonstrated to be effective in diagnosis, severity evaluation, and prognosis in a variety of chronic or acute conditions. This study aims to examine whether NLR, PLR and EDW are independently associated with mortality in necrotizing fasciitis (NF). Methods This study retrospectively enrolled patients diagnosed with NF and based on vitality status during hospitalization or within 30 days after discharge, survival and non-survival groups were defined. For distinctly comparing NLR, PLR, RDW and others, we enrolled the matched healthy controls of the same age and sex as the survivors of NF in a 1:1 ratio, which constituted the healthy control group. Comparisons were made between three groups. Variables tested with a P value < 0.10 were further entered into the multivariate logistic regression model to identify their independent association with mortality. Results A total of 281 subjects were included, including 127 healthy controls, 127 survivors, and 27 nonsurvivors with NF, respectively, indicating a mortality rate of 17.5%. ROC analysis showed that the optimal cutoff value for NLR, PLR and RDW was 11.1, 196.0 and 15.5%, respectively, and was tested as significant only for the first two (P < 0.001, = 0.004). Multivariate logistic analysis showed that NLR ≥ 11.1 (OR, 2.51) and PLR ≥ 196.0 (OR, 2.09) were independently associated with an increased risk of mortality in NF patients, together with age ((OR, 1.28, for each 10-year increment), comorbid diabetes mellitus (OR, 2.69) and liver disease (OR, 1.86), and elevated creatinine level (OR, 1.21 for each 10 umol/L elevation). Conclusion Elevated NLR and PLR are significant and independent predictors of mortality and can be considered for use when evaluating patients at risk of mortality.

Bullous skin signs and laboratory surgical indicators can quickly and effectively differentiate necrotizing fasciitis from cellulitis. Int J Infect Dis 2023; 128:41-50. [PMID: 36521588 DOI: 10.1016/j.ijid.2022.12.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Revised: 12/07/2022] [Accepted: 12/07/2022] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVES The purpose of this prospective study was to investigate the different microorganisms associated with mortality, to evaluate the bullous skin sign, and to identify the positive predictive factors for differentiating necrotizing fasciitis (NF) from cellulitis on initial onset at the emergency department. METHODS This prospective study was conducted in 145 consecutive patients with NF and 159 patients with cellulitis. Age, sex, comorbidities, infection site, microbiological results, condition of skin lesions, laboratory findings, vital signs, and clinical outcomes were compared between the two groups at the time of admission to the emergency room. RESULTS A total of 15 patients in the NF group and two patients in the cellulitis group died, resulting in a mortality rate of 10.3% and 1.3%, respectively. The NF group had a significantly higher incidence of white blood cell counts, band form neutrophil, and C-reactive protein than the patients in the cellulitis group. Hemorrhagic bullae presentation appeared to have significantly associated with NF and death. CONCLUSION The following diagnostic indicators can be effectively used to differentiate NF from cellulitis at the initial onset: presence of hemorrhagic bullae, white blood cell counts >11,000 cells/mm3, band forms >0%, C-reactive protein >100 mg/l, and systolic blood pressure ≤90 mm Hg at the time of consultation.

Abstract
Necrotizing fasciitis (NF) is an uncommon life-threatening necrotizing skin and soft tissue infection. The formation of hemorrhagic bullae is a special skin sign of NF. The purposes of this study were to investigate the incidence of hemorrhagic bullae formation and bacteremia associated with different organisms, to appraise the appropriate use of ceftriaxone, and to compare the clinical and laboratory risk indicators of NF patients with Gram-positive and Gram-negative infections on the initial examination. Methods: From March 2018 to December 2020, there were seventy-four NF patients with positive monomicrobial bacterial cultures enrolled based on surgical confirmation, and were categorized into two groups: the Gram-positive group and the Gram-negative group. Ceftriaxone susceptibility tests were carried out using the standard disk diffusion technique. Data, such as demographics, clinical outcomes, microbiological results, presentations of hemorrhagic bullae, and laboratory findings, were compared among these two groups. Results: The Gram-negative group included 52 patients, of whom 6 patients died, resulting in a mortality rate of 11.5%. The Gram-positive group included 22 patients and none died. Patients with bacteremia, hemorrhagic bullae, shock, fever, higher segmented forms and banded forms, and lower platelet counts constituted higher proportions in the Gram-negative group than in the Gram-positive group. The multivariate analysis identified six variables for the differentiation of Gram-negative and Gram-positive NF: the presentation of bacteremia, hemorrhagic bullae, shock at first consultation, fever with body temperature > 38.5 °C, band forms > 0%, and segmented forms ≦ 74%. A total of 66 isolates (89.2%) was susceptible to ceftriaxone. Conclusions: Gram-negative NF patients were significantly associated with hemorrhagic bullae presentation, blood stream infection, and mortality. Physicians should be alert to NF patients with the appearance of bacteremia, shock, fever, higher WBC banded and segmented forms, and lower platelet counts at the emergency department, with patients revealed to more likely have Gram-negative infections. Ceftriaxone with/without other appropriate antibiotics under the supervision of infectious doctors appeared to be clinically effective for the treatment of NF and blood stream infections.

Abstract
Background Diabetic foot ulcer is one of the major complications for patients with diabetes, and has become an important cause of non-traumatic amputation. Necrotizing fasciitis is a life-threatening soft-tissue infection involving the fascia and subcutaneous tissue. When diabetic foot ulcers are complicated by necrotizing fasciitis (DNF), this increases the risk for amputation and mortality, making DNF treatment more complicated, and eventually leading to amputation and mortality. However, studies on pathogenic bacteria’s distribution and drug sensitivity in DNF patients remain lacking. This study investigated the distribution and susceptibility of pathogenic bacteria in DNF patients, and provided empirical antibacterial guidance for the clinic. Methods In a single diabetic foot center, the results from microbial cultures and drug susceptibility tests of patients with DNF from October 2013 to December 2020 were collected and analyzed. Results A total of 101 DNF patients were included in this study, of whom 94 had positive culture test results. A total of 124 pathogens were cultured, including 76 Gram-positive bacterial strains, 42 Gram-negative bacterial strains, and six fungal strains. Polymicrobial infections accounted for 26.7% and monomicrobial infections accounted for 66.3%. Staphylococcus aureus was the most common bacterium isolated, followed by Enterococcus faecalis and Streptococcus agalactiae. Pseudomonas aeruginosa, Klebsiella pneumoniae, and Proteus mirabilis were the most common Gram-negative bacteria. Thirty-five strains of multi-drug resistant bacteria were isolated, representing 28.2% of the total isolates. Gram-positive bacteria were more sensitive to levofloxacin, moxifloxacin, vancomycin, teicoplanin, tigecycline, and linezolid, while Gram-negative bacteria were more sensitive to amikacin, piperacillin/tazobactam, cefoperazone/sulbactam, ceftazidime, cefepime, imipenem, and meropenem. Conclusions Gram-positive bacteria were the main bacteria isolated from DNF patients. The bacterial composition, the proportion of multi-drug resistant bacteria among the pathogens, and the high risk for amputation should be fully considered in the initial empirical medication, and broad-spectrum antibacterials are recommended.

Abstract
Pediatric musculoskeletal infections often pose a diagnostic challenge due to their frequently vague and nonspecific clinical presentation. Imaging evaluation is a crucial component to diagnostic workup of these entities. Changed epidemiology of these infections over the past 2 decades has resulted in increases in both disease incidence and severity in the pediatric population. Prompt and accurate diagnosis is essential in order to reduce the risk of morbid sequelae, and to optimize patient management. In this article, the unique pathophysiology of musculoskeletal infections and characteristic imaging findings in children compared with adults are reviewed.

Abstract
BACKGROUND Vibrio vulnificus has been reported as the leading causative pathogen of necrotizing fasciitis (NF) and related fatality in the coastal area. Necrotizing fasciitis caused by methicillin-resistant Staphylococcus aureus (MRSA) and V. vulnificus have high mortality rates. The purpose of this prospective study was to clarify the clinical characteristics between death and survival NF patients, to investigate bacteriologic profile and mortality of NF patients, and to compare risk indicators of MRSA and V. vulnificus NF patients. METHODS This prospective study was conducted in 184 consecutive NF patients over a period of three years in a tertiary coastal hospital. Differences in mortality, laboratory findings, microbiology and clinical outcomes were compared between the death and survival groups, and the V. vulnificus and MRSA subgroups. RESULTS Twenty patients died, resulting in a mortality rate of 10.9%, and there were 108 patients with a monomicrobial infection (58.7%). The death group had a significantly higher incidence of shock at emergency room and bacteremia than did the survival group. Vibrio species (40 cases) and S. aureus (31 cases) were the two major pathogens. Significant differences with respect to hepatic dysfunction, shock, the event with seawater or seafood contact, bacteremia, C-reactive protein, mean platelet counts, and the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score were observes between V. vulnificus and MRSA groups. CONCLUSIONS NF patients with both hepatic dysfunction and diabetes mellitus, bacteremia and shock have significantly higher mortality. We should be aware of the increasing incidence of monomicrobial NF and higher mortality rates of Gram-negative pathogens in the warm coastal area. LRINEC score is not a suitable diagnostic indicator for V. vulnificus NF, which is more rapidly progressive and fulminant than MRSA NF. NF needed team works by early suspicion, immediate surgical intervention and aggressive care, which can successfully decrease mortality.

Abstract
Introduction: Necrotizing fasciitis, also referred to necrotizing soft-tissue infection (NSTI), is an infrequent entity that results in orthopedic consultation. It is a rapidly spreading typically associated with a contaminated wound that spreads rapidly along fascial planes resulting in significant morbidity and mortality. However, it is a rare occurrence that such pathology occurs in an atraumatic fashion, which is without a wound through the skin. Case Report: A 33-year-old female with no significant medical history presented to a walk-in orthopedic clinic with increasing ankle pain after a lateral ankle sprain 2 days prior. Patient denies any fevers, chills, shortness of breath, numbness, tingling, paresthesia, or any additional trauma since the initial ankle sprain. The patient was afebrile, maintaining oxygenation, normotensive, but tachycardic to just over 100. Physical examination was only significant for moderate swelling and ecchymosis about the lateral malleolus. X-rays and venous ultrasound were negative for any associated pathology. After a period of observation, the patient acutely decompensated with a significant increase in pain in the lower leg on passive stretch, an increase in compartment firmness and a worsening tachycardia up to the 120’s. The patient was taken emergently for fasciotomies for presumed compartment syndrome. The patient was hemodynamically unstable during the case and transferred to the intensive care unit where she continued to decompensate, requiring multiple vasopressors. The affected extremity became necrotic at the level of the foot and her hemodynamic instability continued, causing a return to the operating room for an emergent guillotine above-knee amputation. The patient progressively stabilized and underwent a formal above-knee amputation 2 days later. Cultures obtained during the second case were positive for Group A Streptococcus. Conclusion: This case highlights the variable presentation of NSTIs as well as has having a high index of suspicion to ensure this highly morbid and fatal disease process is diagnosed expeditiously. This case is also unique in that it developed without any obvious wounds and that monomicrobial Group A Streptococcus was the culprit, while most NSTIs are polymicrobial.

Abstract
Ultrasound (US) is a noninvasive and versatile technology that in recent years found acceptance in almost all the medical specialties, with diagnostic and interventional applications. In the diabetic foot syndrome (DFS), US found specific indications mainly in the screening, quantification, and follow-up of the vascular component of the pathology, but also in the study of the deformities and structural modifications induced by neuropathy and in the diagnosis and surgical management of infections, especially those that induce anatomical changes, like abscesses and fasciitis. This review will summarize all these application of US, giving special attention to the vascular aspects, and on the predominant role that US gained in recent times to guide the indication to revascularization, on the new standardized approach to the study of the arterial tree of the limb and the foot, the so-called duplex ultrasound arterial mapping, which significantly increased the utilization of US to plan the revascularizations in this complex pathology. Outside the vascular fields, the diagnosis of neuropathy and infection and the intraoperative use of US in the surgical management of abscesses and fasciitis will be discussed, leaving the last part to the new and interesting applications of US in the management of DFU, a field that is still in evolution, offering new possibilities to the health care professionals involved in the management of these chronic wounds. The variety of applications both in diagnostic and operative fields makes US a rather versatile technology-a toolkit-that should have a special place among those at reach of the specialists of DFS care.

Abstract
Systemic conditions are associated with higher rates of hand and upper extremity infections, leading to more severe and atypical presentations. Understanding the unique problems associated with some of the most common systemic conditions, including human immunodeficiency virus, diabetes mellitus, and rheumatoid arthritis, can assist the hand surgeon in diagnosing and treating infection in these patients. This article reviews the most common presentation of hand infections for these patients and summarizes current approaches to the management of hand infections for patients with common immunocompromising conditions.

Abstract
Abstract
Background
Pyoderma gangrenosum (PG) is a chronic, ulcerative neutrophilic dermatosis. PG presents a diagnostic challenge, largely due to the many mimicking diseases, the lack of confirmatory laboratory or biological markers, and the absence of widely accepted diagnostic criteria. In particular, PG is often mistaken for necrotizing soft tissue infections (NSTI).
Methods
We reviewed four major textbooks each in general surgery, plastic surgery, trauma surgery, vascular surgery, emergency medicine, and dermatology. We also performed a search of review articles addressing NSTI and necrotizing fasciitis (NF).
Results
Ten out of the 20 non-dermatology textbooks did not list PG anywhere, and only two listed a differential diagnosis for PG. None of the non-dermatology textbooks indicated PG in the NSTI differential diagnosis, while three of the dermatology textbooks included PG in the NSTI differential diagnosis. PG was listed in all of the dermatology textbooks. Only one of the NSTI and NF articles mentioned PG in the differential diagnosis.
Conclusions
There is an underrepresentation in major textbooks of surgery and emergency medicine and in NSTI and NF review articles when it comes to diagnosing PG. This might be leading to trainees and advanced providers in these fields being uninstructed on PG, and likely contributes to PG misdiagnosis and mismanagement. We recommend PG be included in the differential diagnosis of chronic ulcers and NSTI in non-dermatology textbooks. We also suggest adding identification and diagnosis of inflammatory mimickers of NSTI (e.g. PG) in teaching modules in surgical and emergency specialties to address this knowledge gap.

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
INTRODUCTION Necrotising fasciitis is a rare but deadly bacterial infection causing soft tissue and fascial necrosis. It is associated with a mortality rate of 25%. It is characterised by; erythematous skin, which turns dusky blue before haemorrhagic bullae develop; localised pain; and inflammation. It is most commonly found in the extremities, the abdomen or the perineum but is rarely seen in the breast. CASE PRESENTATION We describe a 54-year-old lady who presented with breast erythema and raised inflammatory markers. Initially treated as cellulitis, however when her symptoms did not improve and despite IV antibiotics her bloods worsened, a CT scan was performed which showed a large volume of interstitial soft tissue gas with diffuse fat stranding, consistent with necrotising fasciitis. Debridement of her breast alongside the use of sensitive antibiotics and ITU support led to a satisfactory outcome. DISCUSSION We discuss how an early diagnosis can be made by the recognition of a triad of symptoms common in necrotising fasciitis, and how optimal management can be achieved with the incorporation of imaging to successfully identify the condition and allow targeted debridement of the areas of necrotising fasciitis. CONCLUSION A high index of suspicion should be held if pain is disproportionate to the signs or sepsis is present. To aid an early diagnosis, imaging of the breast should be performed early to avoid delay in treatment.

Abstract
Background Monofocal necrotizing fasciitis (MONF) involves a single site in a rapidly progressing infection and necrosis of the fascia and surrounding soft tissue. Synchronous multifocal necrotizing fasciitis (SMNF), the simultaneous development of NF in multiple noncontiguous sites, is rarely reported. This study aimed to compare the clinical characteristics and outcomes between patients with SMNF and MONF, and to determine the risk factors of SMNF. Methods Our retrospective case-control study compared the clinical characteristics and outcomes, between January 2006 and January 2013, of patients with SMNF and of patients with MONF of the extremities. Results We enrolled 144 patients with NF of the extremities: 19 with SMNF and 125 with MONF. The duration of symptoms before admission was significantly shorter for the former than for the latter (1.7 days vs. 3.3 days, p = 0.001); the prevalence of shock at the initial visit significantly higher (73.7% vs. 36%, p = 0.002); and the total-case postoperative mortality rate significantly higher (68.4% vs. 14.4%, p < 0.001). In further analysis of the total-case mortality, 9 in 13 SMNF deaths (69.2%) within 7 days after fasciotomy were in the majority while 13 with 28-day mortality (72.2%) was the majority of MONF deaths (p < 0.001). SMNF was significantly more likely to involve bacteremia (89.5% vs. 36%, p < 0.001). Independent risk factors for SMNF were liver cirrhosis (LC) (odds ratio [OR] 6.0, p = 0.001) and end-stage renal disease (ESRD) (OR 7.1, p = 0.035). Gram-negative bacteria were most common in SMNF, and Gram-positive bacteria in MONF (83.3% vs. 53.3%, p = 0.005). Vibrio species were the most common single microbial cause (35.4%) of all NF patients and were the overwhelming cause (73.7%) of SMNF. Staphylococcus aureus and group A β-hemolytic streptococcus (45.6%) were the other predominant causes of MONF while both (10.5%) rarely caused multifocal NF. Conclusions SMNF was more fulminant than was MONF. SMNF was attributable primarily to marine Gram-negative bacteria. Physicians should be aware of SMNF because of its extremely high mortality rate.

Abstract
Necrotising fasciitis (NF) is a potentially lethal spread of infection that is uncommonly seen within the province of surgery. Seen mostly in the extremities and the perineal regions, it has been reported rarely to involve the retroperitoneal space and presents with a spectrum of symptoms and signs as such. Literature supports classification of NF based on the microbes involved. Irrespective of the aetiology and the causative organism, NF remains a serious surgical emergency with high morbidity and mortality not only associated with the disease process itself, but also with the extensive surgical debridement it requires in its management along with antimicrobial administration. We present a case of such an infection found in the retroperitoneal space secondary to a perineal infection forming a rare presentation of this deadly process, and how it was successfully managed secondary to timely surgical intervention.

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 Fournier's gangrene is a necrotizing soft-tissue infection (NSTI) that often originates from a break in bowel integrity and affects the perineum, anus, or genitalia. Although the pathogenesis is similar, NSTI caused by a break in bowel integrity less commonly presents as infection of other sites. OBJECTIVE To characterize NSTIs originating from bowel perforation and presenting as infection of the abdominal wall, flank, or thigh but that largely spare the perineum, anus, and genitalia. METHODS We describe a characteristic case and summarize findings from 67 reported cases. RESULTS The causes of bowel injury included trauma (29%), perforated appendicitis (23%), perforated diverticulitis (16%), and perforation of a gastrointestinal tract cancer (16%). The symptomatic prodrome is indolent and nondescript. Most patients have polymicrobial infections and require antibiotic therapy combined with serial surgical debridements. Because the presentation differs from that of typical Fournier's gangrene, recognition of NSTI was delayed in the reported cases, and the associated bowel perforation often was overlooked, leading to delayed surgical treatment. As a result, the mortality rate was >33%, far exceeding that of typical Fournier's gangrene. Delays in diagnosis or surgical intervention predict a poor outcome. CONCLUSIONS An NSTI resulting from bowel perforation can present in an atypical fashion carrying significant morbidity and mortality rates. Delayed diagnosis and treatment of this condition is associated with a poor outcome.

Abstract
Purpose The surgical management of necrotizing fasciitis usually involves early radical/wide and aggressive debridement of involved areas. We describe 5 cases of periorbital necrotizing fasciitis (NF), managed using a computed tomographic (CT)-guided approach to surgical debridement. Methods Retrospective case series review. Results Five patients (4 female, 1 male; age range 39–81) were treated for periorbital NF. The diagnosis was confirmed in all cases with blood cultures and wound swabs. All patients were managed medically by a surviving sepsis regimen. CT scans confirmed suprafascial infection and excluded orbital cellulitis. Four patients had minimal surgical debridement to the surface muscle. All patients survived. Four out of 5 patients underwent delayed reconstruction. Conclusions Periorbital NF behaves differently from NF of other areas. CT-guided surgical debridement of the superficial muscle maximizes preservation of healthy tissue and facilitates reconstruction. Delayed reconstruction allows fibrosis to settle and good cosmetic and functional results are possible. However, NF remains potentially lethal and close observation and a flexible management plan are required.

Abstract
Necrotic fasciitis (NF) is a particularly aggressive and serious infection of the fascia that can penetrate into the musculature and internal organs, resulting in death if not treated promptly. In this work, an integrated microfluidic system composed of micropumps, microvalves, and micromixers was used to automate the detection of pathogens associated with NF. The entire molecular diagnostic process, including bacteria isolation, lysis, nucleic acid amplification and optical detection steps, was enacted on this developed system. Mannose binding lectin coated magnetic beads were first used as probes to isolate all bacteria in a sample. In this work, polymerase chain reaction assays featuring primers specific to genes from each of four NF-causing bacteria (Vibrio vulnificus, Aeromonas hydrophila, and methicillin-sensitive and resistant Staphylococcus aureus) were used to rapidly and exclusively verify the presence of the respective bacterial strains, and the limits of detection were experimentally found to be 11, 1960, 14, and 11 400 colony forming units/reaction, respectively; all values reflect improvement over ones reported in literature. This integrated microfluidic chip may then be valuable in expediting diagnosis and optimizing treatment options for those with NF; such diagnostic improvements could ideally diminish the need for amputation and even reduce the morality rate associated with this life-threatening illness.

Abstract
Necrotizing fasciitis is a life-threatening clinical pattern, which may lead to multi-organ failure and death with delayed diagnosis or inadequate treatment. We report on a 68-year old patient who developed necrotizing fasciitis of the right elbow with multiorgan failure and long-term ventilation after an accidental and minor injury. The patient survived as a result of an early diagnosis and surgical intervention. In this case report we want to clarify the diagnosis and treatment of necrotizing fasciitis and give an overview of the recent literature on the topic.

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
Necrotizing fasciitis (NF) represents a rapidly progressive, life-threatening infection involving skin, soft tissue, and deep fascia. An early diagnosis is crucial to treat NF effectively. The disease is generally due to an external trauma that occurs in predisposed patients: the most important risk factor is represented by diabetes mellitus. NF is classified into 3 different subtypes according to bacterial strains responsible: type 1 associated to polymicrobial infection, type 2 NF, generally associated to Streptococcus species, often associated to Staphylococcus aureus and, eventually, Type 3, due to Gram-negative strains, such as Clostridium difficile or Vibrio. NF is usually characterized by the presence of the classic triad of symptoms: local pain, swelling, and erythema. In daily clinical practice immune-compromised or neuropathic diabetic patients present with atypical symptomatology. This explains the high percentage of misdiagnosed cases in the emergency department and, consequently, the worse outcome presented by these patients. Prompt aggressive surgical debridement and antibiotic systemic therapy are the cornerstone of its treatment. These must be associated with an accurate systemic management, consisting in nutritional support, glycemic compensation, and hemodynamic stabilization. Innovative methods, such as negative pressure therapy, once the acute conditions have resolved, can help fasten the surgical wound closure. Prompt management can improve prognosis of patients affected from NF reducing limb loss and saving lives.

Abstract
Necrotizing fasciitis (NF) is an aggressive and life-threatening infection of skin and soft tissue characterized by widespread fascial necrosis, leads to gross morbidity and mortality if left untreated. Although MRSA has become a common isolate associated with skin and soft tissue infections globally over the past few years, monomicrobial MRSA NF has been reported only in a few studies. Our case represents the development of NF followed by trivial trauma salvaged with daptomycin and amputation of the affected limb. Prompt diagnosis and surgical management with empiric MRSA cover in areas where community acquired MRSA (CA-MRSA) is endemic for suspected cases of necrotizing fasciitis can prevent the dreaded consequences.

Abstract
INTRODUCTION Necrotising soft tissue infection (NSTI) is a rare but life threatening diagnosis. Geographic, economic and social variances influence presentation and prognosis. As the current literature does not reflect a UK metropolitan population, we conducted a retrospective chart review to establish pertinent features relevant to our practice. METHODS Patients with histologically confirmed diagnoses of NSTI presenting to two London teaching hospitals between January 2007 and July 2013 were included in the study. Features of presentation, surgical and medical management, microbiological findings and outcome were evaluated. RESULTS Twenty-four patients with histologically confirmed NSTI were included. Two age clusters were identified, with means of 46 years (standard deviation [SD]: 10 years) and 80 years (SD: 6 years). Pain, erythema and sepsis were common findings. Hypertension, hypercholesterolaemia and type II diabetes mellitus were common co-morbidities. A third of younger patients had human immunodeficiency virus or hepatitis C, with a quarter dependent on drugs and/or alcohol. The mean Laboratory Risk Indicator for Necrotising Fasciitis (LRINEC) score was 5.8 (SD: 3.3). The lower extremities, groin and perineum were common sites of infection. Fourteen patients required inotropic support and seventeen required transfusions. The median number of surgical procedures was 5 (range: 1-17). Group A Streptococcus was the most frequently identified pathogen. Five patients died. Being elderly, female sex and failure to use clindamycin as a first-line antibiotic were associated with significantly higher mortality. CONCLUSIONS In contrast to other recent series, group A streptococcal monomicrobial NSTI remains the most common presentation in our population. Survival is anticipated in young patients, regardless of premorbid status. Elderly patients have a poor prognosis. The negative predictive value of the LRINEC score is questioned. Use of clindamycin as a first-line antibiotic is supported.

Abstract
The continued emergence of antibiotic-resistant bacteria and the development of only a few new classes of antibiotics over the past 50 years have made the treatment of acute hand infections problematic. Prompt diagnosis and treatment are important, because hand stiffness, contractures, and even amputation can result from missed diagnoses or delayed treatment. The most common site of hand infections is subcutaneous tissue and the most common mechanism is trauma. An immunocompromised state, intravenous drug abuse, diabetes mellitus, and steroid use all predispose to infections.

Abstract
Background Polymicrobial infections caused by combinations of different bacteria are being detected with an increasing frequency. The evidence of such complex infections is being revealed through the use of novel molecular and culture-independent methods. Considerable progress has been made in the last decade regarding the diagnostic application of such molecular techniques. In particular, 16S rDNA-based sequencing and even metagenomic analyses have been successfully used to study the microbial diversity in ecosystems and human microbiota. Here, we utilized denaturing high-performance liquid chromatography (DHPLC) as a diagnostic tool for identifying different bacterial species in complex clinical samples of a patient with a chronic foot ulcer. Case presentation A 45-year-old female suffered from a chronic 5x5cm large plantar ulcer located in the posterior calcaneal area with subcutaneous tissue infection and osteomyelitis. The chronic ulcer developed over a period of 8 years. Culture and DHPLC revealed a distinct and location-dependent polymicrobial infection of the ulcer. The analysis of a superficial biopsy revealed a mixture of Staphylococcus aureus, Proteus vulgaris, and Fusobacterium nucleatum, whereas the tissue-deep biopsy harbored a mixture of four different bacterial species, namely Gemella morbillorum, Porphyromonas asaccharolytica, Bacteroides fragilis, and Arcanobacterium haemolyticum. Conclusions This clinical case highlights the difficulties in assessing polymicrobial infections where a mixture of fastidious, rapid and slow growing bacteria as well as anaerobes exists as structured communities within the tissue architecture of chronic wound infections. The diagnosis of this multilayered polymicrobial infection led to a microbe-adapted antibiotic therapy, targeting the polymicrobial nature of this infection in addition to a standard local wound treatment. However, a complete wound closure could not be achieved due to the long-lasting extensive destruction of tissue.

Abstract
The authors discuss the evolution of the evaluation and management of colonic trauma, as well as the debate regarding primary repair versus fecal diversion. Their evidence-based review covers diagnosis, management, surgical approaches, and perioperative care of patients with colon-related trauma. The management of traumatic colon injuries has evolved significantly over the past 50 years; here the authors describe a practical approach to the treatment and management of traumatic injuries to the colon based on the most current research. However, management of traumatic colon injuries remains a challenge and continues to be associated with significant morbidity. Familiarity with the different methods to the approach and management of colonic injuries will allow surgeons to minimize unnecessary complications and mortality.

Abstract
BACKGROUND Necrotizing soft tissue infections often are characterized by fulminant presentation and lethal outcomes. Besides critical care support and antibiotic therapy, aggressive surgical treatment is important for the therapy of necrotizing fasciitis. The aim of this study was to develop a procalcitonin (PCT) ratio indicating successful surgical intervention. METHODS The study group consisted of 38 patients treated with clinical signs of sepsis caused by a necrotizing soft tissue infection. All patients received radical surgical treatment, and serum levels of PCT and C-reactive protein were monitored postoperatively. The ratio of day 1 to day 2 was calculated and correlated with the successful elimination of the infectious source and clinical recovery. RESULTS An eradication of the infectious focus was successfully performed in 84% of patients, averaging 1.9 operations (range 1 to 6) to achieve an elimination of the infectious source. The PCT ratio was significantly higher in the group of patients with successful surgical intervention (1.665 vs .9, P < .001). A ratio higher than the calculated cutoff of 1.14 indicated successful surgical treatment with a sensitivity of 83.3% and a specificity of 71.4%. The positive predictive value was 75.8%, and the negative predictive value was 80.0%. CONCLUSIONS The PCT ratio of postoperative day 1 to day 2 following major surgical procedures for necrotizing soft tissue infections represents a valuable clinical tool indicating successful surgical eradication of the infectious focus.

Abstract
Escherichia coli (E. coli) is associated with necrotizing fasciitis (type I) and can induce enough damage to tissue causing hypoxia. Three ester derivatives of the broad-spectrum antibiotic ciprofloxacin were placed into bacteria culture simultaneously with the parent ciprofloxacin (drug 1) to ascertain the level of antibacterial activity. The n-propyl (drug 2), n-pentyl (drug 3), and n-octyl (drug 4) esters of ciprofloxacin were synthesized under mixed phase conditions and by microwave excitation. The formation of ester derivatives of ciprofloxacin modified important molecular properties such as Log P and polar surface area which improves tissue penetration, yet preserved strong antibacterial activity. The Log P values for drugs 1, 2, 3, and 4 became -0.701, 0.437, 1.50, and 3.02, respectively. The polar surface areas for drugs 1, 2, 3, and 4 were determined to be 74.6 Angstroms(2), 63.6 Angstroms(2), 63.6 Angstroms(2), and 63.6 Angstroms(2), respectively. These values of Log P and polar surface area improved tissue penetration, as indicated by the determination of dermal permeability coefficient (K p ) and subsequently into the superficial fascial layer. All drugs induced greater than 60% bacterial cell death at concentrations less than 1.0 micrograms/milliliter. The ester derivatives of ciprofloxacin showed strong antibacterial activity toward penicillin resistant E. coli.

Abstract
Necrotizing soft tissue infections are rapidly progressive infections with a high rate of mortality. One type of necrotizing soft tissue infection is caused by marine gram-negative bacteria and commonly occurs in immunocompromised hosts. These types of infections are more common in patients with chronic liver disease, possibly because of impaired iron metabolism. We present the case of a rapidly progressive necrotizing soft tissue infection caused by Edwardsiella tarda, a marine gram-negative pathogen common in catfish. Few extraintestinal infections of E tarda have been described previously. Our patient had hepatitis C and was exposed to the bacteria by a puncture injury from a wild catfish. His infection required multiple debridements and ultimately required a transhumeral amputation for local control of the infection.

Abstract
Necrotizing fasciitis is a rare, life-threatening infection most commonly seen in patients with diabetes mellitus, intravenous drug abuse, and immunocompromised conditions. The extremities are the primary sites of involvement in as many as two thirds of the cases. In a significant proportion of patients, the extremities are involved as a result of trauma, needle puncture or extravasation of drugs. The infection is usually polymicrobial. Treatment involves broad-spectrum antibiotics and multiple surgical debridements or amputation. We present a patient with necrotizing fasciitis of the upper limb and present our experience with this often lethal condition.

Abstract
Anthrax is caused by infection with Bacillus anthracis, a spore-forming gram-positive bacterium. A major virulence factor for B. anthracis is an immunomodulatory tripartite exotoxin that has been reported to alter immune cell chemotaxis and activation. It has been proposed that B. anthracis infections initiate through entry of spores into the regional draining lymph nodes where they germinate, grow, and disseminate systemically via the efferent lymphatics. If this model holds true, it would be predicted that surgical removal of infected tissues, debridement, would have little effect on the systemic dissemination of bacteria. This model was tested through the development of a mouse debridement model. It was found that removal of the site of subcutaneous infection in the ear increased the likelihood of survival and reduced the quantity of spores in the draining cervical lymph nodes (cLN). At the time of debridement 12 hours post-injection measurable levels of exotoxins were present in the ear, cLN, and serum, yet leukocytes within the cLN were activated; countering the concept that exotoxins inhibit the early inflammatory response to promote bacterial growth. We conclude that the initial entry of spores into the draining lymph node of cutaneous infections alone is not sufficient to cause systemic disease and that debridement should be considered as an adjunct to antibiotic therapy.

Abstract
Background Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a prevalent pathogen of necrotizing fasciitis (NF) in Taiwan. A four-year NF cases and clinical and genetic differences between hospital acquired (HA)- and community-acquired (CA)-MRSA infection and isolates were investigated. Methods A retrospective study of 247 NF cases in 2004-2008 and antimicrobial susceptibilities, staphylococcal chromosomal cassette mec (SCCmec) types, pulsed field gel electrophoresis (PFGE) patterns, virulence factors, and multilocus sequence typing (MLST) of 16 NF-associated MRSA in 2008 were also evaluated. Results In 247 cases, 42 microbial species were identified. S. aureus was the major prevalent pathogen and MRSA accounted for 19.8% of NF cases. Most patients had many coexisting medical conditions, including diabetes mellitus, followed by hypertension, chronic azotemia and chronic hepatic disease in order of decreasing prevalence. Patients with MRSA infection tended to have more severe clinical outcomes in terms of amputation rate (p < 0.05) and reconstruction rate (p = 0.001) than those with methicillin-sensitive S. aureus or non-S. aureus infection. NF patients infected by HA-MRSA had a significantly higher amputation rate, comorbidity, C-reactive protein level, and involvement of lower extremity than those infected by CA-MRSA. In addition to over 90% of MRSA resistant to erythromycin and clindamycin, HA-MRSA was more resistant than CA-MRSA to trimethoprim-sulfamethoxazole (45.8% vs. 4%). ST59/pulsotype C/SCCmec IV and ST239/pulsotype A/SCCmec III isolates were the most prevalent CA- and HA-MRSA, respectively in 16 isolates obtained in 2008. In contrast to the gene for γ-hemolysin found in all MRSA, the gene for Panton-Valentine leukocidin was only identified in ST59 MRSA isolates. Other three virulence factors TSST-1, ETA, and ETB were occasionally identified in MRSA isolates tested. Conclusion NF patients with MRSA infection, especially HA-MRSA infection, had more severe clinical outcomes than those infected by other microbial. The prevalent NF-associated MRSA clones in Taiwan differed distinctly from the most predominant NF-associated USA300 CA-MRSA clone in the USA. Initial empiric antimicrobials with a broad coverage for MRSA should be considered in the treatment of NF patients in an endemic area.

Abstract
Necrotizing fasciitis is a rapidly progressive infection and is a necrosis of the fascia and surrounding tissues. Despite recent advances in its management, outcomes have not improved and mortality rate is still high. Between September 2007 and August 2009, we prospectively studied twenty-four histopathologically proven necrotizing fasciitis patients to assess the prognostic factors that indicate the outcome. Mortality rate was 20.8%. Twelve patients (50%) improved, while seven patients (29.2%) were complicated by limb loss. Mortality rates related to upper and lower limb involvement were similar (20% vs. 22.2%). The rates of gangrene and amputation in patients with diabetes mellitus were significantly higher than other comorbidities. Patients with gram-positive infections had significantly lower rates of amputation (15.4% vs. 54.5%, P = 0.04). Mean band cell count and serum potassium level were significantly higher in the nonsurvivors same as leukocyte count in the patients with gangrene, while serum sodium level was significantly lower in nonsurvivors. We conclude that hyponatremia, hyperkalemia, and increased band cells in the peripheral blood of patients may be useful parameters in distinguishing life-threatening necrotizing fasciitis; hence, we recommended lower threshold to amputation during surgery for this group of patients.

Abstract
BACKGROUND Necrotizing fasciitis (NF) is a serious infection of soft tissues. This paper presents experience with pediatric NF and suitability of conservative surgery in its management. MATERIALS AND METHODS In this retrospective study, 70 patients of NF were managed during the study period of eight years. The study was divided into two time periods- first period (June 1998 to June 2001- group 1) and second period (June 2001 to June 2006- group 2). The parameters studied were age, sex, site of involvement and treatment. The treatment included intravenous antibiotics, supportive therapy and either aggressive (group 1) or conservative surgery (group 2). RESULTS Age of presentation ranged from 10 days to 11 years. Male to female ratio was 1.69:1. Back was the commonest site to be involved. Culture reports were polymicrobial in 70% with predominance of Staphylococcus species. Predisposing factors included malnourishment, boils, scratch injury, intravenous cannulation and injections. Conservative surgery had better outcome in terms of hospital stay, complications and cost of treatment. CONCLUSION NF is a serious and disease which requires immediate and all out attention. Early diagnosis, aggressive supportive treatment and conservative surgery improve survival.

Abstract
Cellulitis is an acute infection of the dermal and subcutaneous layers of the skin, often occurring after a local skin trauma. It is a common diagnosis in both inpatient and outpatient dermatology, as well as in the primary care setting. Cellulitis classically presents with erythema, swelling, warmth, and tenderness over the affected area. There are many other dermatologic diseases, which can present with similar findings, highlighting the need to consider a broad differential diagnosis. Some of the most common mimics of cellulitis include venous stasis dermatitis, contact dermatitis, deep vein thrombosis, and panniculitis. History, local characteristics of the affected area, systemic signs, laboratory tests, and, in some cases, skin biopsy can be helpful in confirming the correct diagnosis. Most patients can be treated as an outpatient with oral antibiotics, with dicloxacillin or cephalexin being the oral therapy of choice when methicillin-resistant Staphylococcus aureus is not a concern.

Abstract
Introduction Necrotizing fasciitis (NF) is a life threatening infectious disease with a high mortality rate. We carried out a microbiological characterization of the causative pathogens. We investigated the correlation of mortality in NF with bloodstream infection and with the presence of co-morbidities. Methods In this retrospective study, we analyzed 323 patients who presented with necrotizing fasciitis at two different institutions. Bloodstream infection (BSI) was defined as a positive blood culture result. The patients were categorized as survivors and non-survivors. Eleven clinically important variables which were statistically significant by univariate analysis were selected for multivariate regression analysis and a stepwise logistic regression model was developed to determine the association between BSI and mortality. Results Univariate logistic regression analysis showed that patients with hypotension, heart disease, liver disease, presence of Vibrio spp. in wound cultures, presence of fungus in wound cultures, and presence of Streptococcus group A, Aeromonas spp. or Vibrio spp. in blood cultures, had a significantly higher risk of in-hospital mortality. Our multivariate logistic regression analysis showed a higher risk of mortality in patients with pre-existing conditions like hypotension, heart disease, and liver disease. Multivariate logistic regression analysis also showed that presence of Vibrio spp in wound cultures, and presence of Streptococcus Group A in blood cultures were associated with a high risk of mortality while debridement > = 3 was associated with improved survival. Conclusions Mortality in patients with necrotizing fasciitis was significantly associated with the presence of Vibrio in wound cultures and Streptococcus group A in blood cultures.

Abstract
Necrotizing fasciitis is a rapidly progressive, potentially fatal infection of the superficial fascia and subcutaneous tissue. It is rare in children. We report three such cases in which differentiating from common soft tissue infection was challenging. High index of suspicion is important as management initiated at an early stage is rewarding.
