Abstract
Post-burn necrotizing fasciitis (PBNF) is a serious and potentially life-threatening infection that occurs after a burn injury. It is characterized by rapid destruction of soft tissue and muscle and is usually caused by a bacterial infection. Diabetic ketoacidosis (DKA) is another serious complication of diabetes, which can occur when the body does not have enough insulin to break down glucose for energy. This causes the body to start breaking down fat for energy instead, leading to various complications. The present study discusses the association between PBNF and DKA in a patient with diabetes. Here is a case of a post-auricular abscess and a precipitated DKA. The abscess was located near the site of the previous burn injury that happened 20 years ago and was believed to have developed as a result of thick scar tissue. The patient was given adequate hydration, intravenous antibiotics, and insulin therapy. However, the abscess continued to grow with increasing insulin requirements and the patient underwent incision and drainage to remove the infected tissue, and an aggressive debridement was carried out. Thus, this case highlights the importance of closely monitoring blood sugar levels in patients with a history of burn injury and diabetes, as well as the potential for infections to precipitate DKA. Timely intervention, including incision and drainage, can lead to successful resolution of symptoms and improved outcomes.

Prospective Validation and Comparison of Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) and Site Other Than Lower Limb, Immunosuppression, Age, Renal Impairment, and Inflammatory Markers (SIARI) Scoring Systems for Necrotizing Fasciitis. J Surg Res 2023; 283:719-725. [PMID: 36462382 DOI: 10.1016/j.jss.2022.11.001] [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: 04/23/2022] [Revised: 10/27/2022] [Accepted: 11/02/2022] [Indexed: 12/03/2022]
Abstract
INTRODUCTION Necrotizing fasciitis (NF) is a rapidly progressing infection of the soft tissues associated with high morbidity and mortality and hence it is a surgical emergency. Early diagnosis and treatment are of paramount importance. LRINEC (Laboratory Risk Indicator for Necrotizing Fasciitis) and SIARI (Site other than lower limb, Immunosuppression, Age, Renal impairment, and Inflammatory markers) scoring systems have been established for early and accurate diagnosis of necrotizing fasciitis. This study compared the two scoring systems for diagnosing NF, predicting management, and elucidating the prognostic performance for re-operation and mortality. METHODS This prospective study was conducted in PGIMER Chandigarh, India, between February 2020 and June 2021. The study was approved by the Institutional Review Board (No. INT/IEC/2020-90). The clinical presentation, laboratory parameters, and imaging were used to classify patients into NF or severe cellulitis groups. We also calculated the LRINEC and SIARI scores. Demographic variables and mortality were recorded. The area under the receiver operating characteristic was used to express the accuracy of both scores at a cut-off LRINEC and SIARI scores of ≥6 and ≥ 4, respectively. RESULTS The study comprised 41 patients with NF and 11 with severe cellulitis. Informed written consent was taken from all the participants. At LRINEC score ≥6, the C-statistic for NF diagnosis was 0.839 (95% confidence interval [CI] 0.682-0.995, P 0.001), which was better than SIARI score at ≥ 4, C-statistic of 0.608 (95% CI 0.43-0.787, P 0.297). Both scores accurately predicted 30-day mortality. The LRINEC score showed a C-statistic of 0.912 (95% CI 0.798-1, P 0.001). Simultaneously, the SIARI score showed 70% sensitivity and 77% specificity, with a C-statistic of 0.805 (0.62-0.99, P = 0.017). CONCLUSIONS LRINEC score is an effective diagnostic tool for distinguishing necrotizing fasciitis from severe cellulitis. Additional research is required to establish the SIARI score's external validity.

Abstract
Background: Frequency, microbiology, and outcomes of necrotizing soft tissue infections (NSTIs) could vary across the United States because of differences in locoregional and environmental factors. We synthesized the literature from across the regions of the United States on NSTIs in a systematic review/meta-analysis. Methods: PubMed, ProQuest, Scopus, and Web of Science databases were systematically searched and screened. DerSimonian-Laird random-effects meta-analyses were performed using 'meta' package in R to determine pooled prevalences. Meta-regression analyses examined moderator effects of risk factors. Results: Twenty-seven studies (2,242 total patients) were included. Pooled prevalences of polymicrobial and monomicrobial infections were 52.2% and 39.9%, respectively. The prevalence of monomicrobial NSTIs increased over the last two decades (p = 0.018), whereas polymicrobial infections declined (p = 0.003). Meta-regression analysis showed that most polymicrobial NSTIs were Fournier gangrene (p < 0.001), whereas monomicrobial NSTIs mostly affected extremities (p < 0.001). Staphylococcus aureus was the most common organism isolated (predominantly in the South), followed by Bacteroides spp. (predominately in the East) and Streptococcus pyogenes. Methicillin-resistant Staphylococcus aureus (MRSA) accounted for 11.9% of NSTIs, mainly in the South. The overall mortality rate was 17.8% and declined over last two decades (p < 0.001), with the lowest rate reported in the last decade at 13% without any regional differences. Conclusions: Advancement in the management of NSTIs may have contributed to the observed decline in NSTI-related mortality in the United States. However, the proportion of monomicrobial NSTIs seems to be increasing, possibly because of increased comorbidities affecting extremities. Causative organisms varied by region. Multi-center observational studies are warranted to confirm our observations.

Abstract
Necrotizing fasciitis of the head and neck is a rare, very severe disease, which, in most cases, originates from odontogenic infections and frequently ends with the death of the patient. Rapid surgical intervention in combination with a preferably pathogen-specific antibiotic therapy can ensure patients’ survival. The question arises concerning which pathogens are causative for the necrotizing course of odontogenic inflammations. Experimental 16S-rRNA gene analysis with next-generation sequencing and bioinformatics was used to identify the microbiome of patients treated with an odontogenic necrotizing infection and compared to the result of the routine culture. Three of four patients survived the severe infection, and one patient died due to septic multiorgan failure. Microbiome determination revealed findings comparable to typical odontogenic abscesses. A specific pathogen which could be causative for the necrotizing course could not be identified. Early diagnosis and rapid surgical intervention and a preferably pathogen-specific antibiotic therapy, also covering the anaerobic spectrum of odontogenic infections, are the treatments of choice. The 16S-rRNA gene analysis detected significantly more bacteria than conventional methods; therefore, molecular methods should become a part of routine diagnostics in medical microbiology.

Abstract
BACKGROUND Frequency, microbiology, and outcomes of necrotizing soft tissue infections vary based on locoregional and environmental factors; however, there has been no global survey of these patterns. We performed a systematic review/meta-analysis on published reports of necrotizing soft tissue infections from across the globe. METHODS Peer-reviewed empirical studies examining rates of polymicrobial and monomicrobial necrotizing soft tissue infections with microbial isolation and overall mortality rate were extracted along with geographic location using PubMed, Scopus, ProQuest, and Web of Science. Random-effects meta-analyses and sensitivity analyses were performed, adjusting for publication bias. Meta-regression analyses examined moderator effects of risk factors. RESULTS One hundred and five studies (8,718 total patients) were included. Pooled prevalence of polymicrobial and monomicrobial infections were 53% and 37.9%, respectively. Truncal necrotizing soft tissue infections were commonly polymicrobial (P < .001), whereas monomicrobial infections prevailed in extremities (P = .008). Global prevalence of monomicrobial necrotizing soft tissue infections was observed to increase by 1.1% annually (P = .003). Staphylococcus aureus was the most common organism globally and in North America, Asia, the Middle East, and Africa, followed by Streptococcus pyogenes and Escherichia coli. Methicillin-resistant S. aureus accounted for 16% of necrotizing soft tissue infections globally. Overall mortality was 23.1%, observed to decline globally over the last decade (P = .020). No regional differences were noted for mortality. CONCLUSION Although polymicrobial infections remain predominant worldwide, the incidence of monomicrobial infections is increasing. The observed decline in necrotizing soft tissue infection-related mortality is encouraging and may reflect advances in management, despite major variations in available healthcare resources globally.

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
Necrotizing fasciitis is a devastating, rapidly pro-gressive soft tissue infection. We present an unusual case of Escherichia coli necrotizing fasciitis following renal transplant. The patient was a 50-year-old woman previously on long-term hemodialysis who presented with left thigh erythema adjacent to the site of a central venous catheter 5 days after renal transplant. The classical features of necrotizing fasciitis were initially absent, and, despite aggressive resuscitation and debridement, she did not survive. Monomicrobial E. coli necrotizing fasciitis is rare, especially in this cohort of patients. Immunosuppression is a known risk factor for infection, and patients may present atypically. Shock and erythema may be the only clues to infection. Necrotizing fasciitis must be considered in acutely unwell renal transplant recipients so that immediate and life-saving surgical debridement can be delivered.

Abstract
BACKGROUND There is limited information about bacterial isolates that are present on the equine midline incision during and following exploratory laparotomy. OBJECTIVES To investigate the bacterial species cultured from the ventral midline pre-, intra- and post- laparotomy, whether particular bacterial isolates are associated with the development of surgical site infections (SSIs) and to report the antimicrobial resistance phenotypes of these isolates. STUDY DESIGN Prospective cohort study. METHODS The ventral midline of 31 horses undergoing exploratory laparotomy was sampled for bacterial culture at set time-points pre, intra and post-operatively. Inclusion criteria were that horses must have undergone exploratory laparotomy within 90 min of the initial colic examination upon hospital admission and must not have been placed in a stable prior to surgery. SSI was defined as any purulent or serous discharge from the laparotomy incision of >24 h duration. RESULTS Seven horses (22.6%) developed a SSI. None of the variables tested were associated with the altered risk of SSI. The prevalence of a positive bacterial culture from the incision increased progressively over time and a variety of bacteria were isolated. A positive intra-operative culture was not a predictor of SSI; and when a SSI did occur, it was due to a different bacterial isolate. MRSA and ESBL-producers were identified in the post-operative period in one and four different horses respectively, but none of these developed a SSI. MAIN LIMITATIONS Sampling was limited to hospitalisation and no culture results were available for horses developing SSI following hospital discharge. CONCLUSIONS A variety of bacterial species may be isolated from equine laparotomy incisions peri-operatively without development of SSI. SSI does not appear to be solely related to bacterial contamination of the incision peri-operatively and other mechanisms such as bacteraemia merit further investigation.

Abstract
Necrotizing soft tissue infections are rare but are associated with high rates of morbidity and mortality. The use of bedside or intraoperative frozen sections has been reported to be associated with faster diagnosis and better outcomes; however, to date no large studies have been published to determine the sensitivity and specificity of frozen sections in this setting. Twenty years of cases suspicious for necrotizing soft tissue infection at a large academic referral center were reviewed, blinded to the final clinical diagnosis (gold standard). Cases were assessed for the number of neutrophils, extent of necrosis, presence of thrombi, bacteria, karyorrhexis, and fibrin, and concordance with permanent sections. A total of 166 cases suspicious for necrotizing soft tissue infection had frozen section slides available for review. Sixty-three cases were clinically determined to be positive and 103 negative. Neutrophils, necrosis, thrombi, bacteria, karyorrhexis, and fibrin were present in both positive and negative cases; however, no histological feature or combination of features was found to be both sensitive and specific for necrotizing soft tissue infection. The combined presence of necrosis and frequent neutrophils was 73% sensitive and 68% specific, with a 58% positive predictive value and 80% negative predictive value. The additional observation of bacteria decreased sensitivity to 32%, whereas raising specificity to 91%, with 69% positive predictive value and 68% negative predictive value. Thirty-two cases (19%) contained findings identified on permanent sections (eg, bacteria) not observed on frozen section slides, highlighting the risk of false negatives owing to technical limitations or sampling errors. Frozen sections in necrotizing soft tissue infections and negative cases may show similar histological findings. Combined with the risk of false negatives, these results suggest that frozen sections are likely to be of limited clinical utility due to lack of sensitivity and specificity, and risk for delayed diagnosis and treatment.

Abstract
BACKGROUND Necrotizing soft-tissue infections (NSTIs) result in significant morbidity and mortality rates, with as many as 76% of patients dying during their index admission. Published data suggest NSTIs rarely involve fungal infections in immunocompetent patients. However, because of the recent recognition of fungal infections in our population, we hypothesized that such infections frequently complicate NSTIs and are associated with higher morbidity and mortality rates. METHODS A prospectively maintained Acute and Critical Care Surgery (ACCS) database spanning 2008-2015 and including more than 7,000 patients was queried for patients with NSTIs. Microbiologic data, demographics, and clinical outcomes were abstracted. Risk factors and outcomes associated with NSTI with positive intra-operative fungal cultures were determined. Frequencies were compared by χ2 and continuous variables by the Student t-test using SPSS. Because the study included only archived data, no patient permission was needed. RESULTS A total of 230 patients were found to have NSTIs; 197 had intra-operative cultures, and 21 (10.7%) of these were positive for fungi. Fungal infection was more common in women, patients with higher body mass index (BMI), and patients who had had prior abdominal procedures. There were no significant differences in demographics, co-morbidities, or site of infection. The majority of patients (85.7%) had mixed bacterial and fungal infections; in the remaining patients, fungi were the only species isolated. Most fungal cultures were collected within 48 h of hospital admission, suggesting that the infections were not hospital acquired. Patients with positive fungal cultures required two more surgical interventions and had a three-fold greater mortality rate than patients without fungal infections. CONCLUSIONS This is the largest series to date describing the impact of fungal infection in NSTIs. Our data demonstrate a three-fold increase in the mortality rate and the need for two additional operations. Consideration should be given to starting patients on empiric anti-fungal therapy in certain circumstances.

Abstract
Bisphosphonates are drugs used to treat osteoclast-mediated bone resorption, including osteoporosis, Paget disease, multiple myeloma, cancer-related osteolysis, and malignant hypercalcemia. The use of these drugs has increased in recent years as have their complications, especially bisphosphonate-related osteonecrosis of the jaw (BRONJ), which more frequently affects the mandible. Here we report a case of BRONJ with a particularly unfavorable course due to cervical inflammation that developed into necrotizing fasciitis, followed by multiorgan involvement leading to septic shock and death.

Abstract
Staphylococcus aureus, although generally identified as a commensal, is also a common cause of human bacterial infections, including of the skin and other soft tissues, bones, bloodstream, and respiratory tract. The history of S. aureus treatment is marked by the development of resistance to each new class of antistaphylococcal antimicrobial drugs, including the penicillins, sulfonamides, tetracyclines, glycopeptides, and others, complicating therapy. S. aureus isolates identified in the 1960s were sometimes resistant to methicillin, a ß-lactam antimicrobial active initially against a majority S. aureus strains. These MRSA isolates, resistant to nearly all ß-lactam antimicrobials, were first largely confined to the health care environment and the patients who attended it. However, in the mid-1990s, new strains, known as community-associated (CA-) MRSA strains, emerged. CA-MRSA organisms, compared with health care-associated (HA-) MRSA strain types, are more often susceptible to multiple classes of non ß-lactam antimicrobials. While infections caused by methicillin-susceptible S. aureus (MSSA) strains are usually treated with drugs in the ß-lactam class, such as cephalosporins, oxacillin or nafcillin, MRSA infections are treated with drugs in other antimicrobial classes. The glycopeptide drug vancomycin, and in some countries teicoplanin, is the most common drug used to treat severe MRSA infections. There are now other classes of antimicrobials available to treat staphylococcal infections, including several that have been approved after 2009. The antimicrobial management of invasive and noninvasive S. aureus infections in the ambulatory and in-patient settings is the topic of this review. Also discussed are common adverse effects of antistaphylococcal antimicrobial agents, advantages of one agent over another for specific clinical syndromes, and the use of adjunctive therapies such as surgery and intravenous immunoglobulin. We have detailed considerations in the therapy of noninvasive and invasive S. aureus infections. This is followed by sections on specific clinical infectious syndromes including skin and soft tissue infections, bacteremia, endocarditis and intravascular infections, pneumonia, osteomyelitis and vertebral discitis, epidural abscess, septic arthritis, pyomyositis, mastitis, necrotizing fasciitis, orbital infections, endophthalmitis, parotitis, staphylococcal toxinoses, urogenital infections, and central nervous system infections.

Triple diagnostics for early detection of ambivalent necrotizing fasciitis. World J Emerg Surg 2016; 11:51.

Abstract
BACKGROUND Necrotizing fasciitis is an uncommon, rapidly progressive and potential lethal condition. Over the last decade time to surgery decreased and outcome improved, most likely due to increased awareness and more timely referral. Early recognition is key to improve mortality and morbidity. However, early referral frequently makes it a challenge to recognize this heterogeneous disease in its initial stages. Signs and symptoms might be misleading or absent, while the most prominent skin marks might be in discrepancy with the position of the fascial necrosis. Gram staining and especially fresh frozen section histology might be a useful adjunct. METHODS Retrospective analysis of 3 year period. Non-transferred patients who presented with suspected necrotizing fasciitis are included. ASA classification was determined. Mortality was documented. RESULTS In total, 21 patients are included. Most patients suffered from severe comorbidities. In 11 patients, diagnoses was confirmed based on intra-operative macroscopic findings. Histology and/or microbiotic findings resulted in 6/10 remaining patients in a change in treatment strategy. In total, 17 patients proved to suffer necrotizing fasciitis. In the cohort series 2 patients died due to necrotizing fasciitis. CONCLUSION In the early phases of necrotizing fasciitis, clinical presentation can be ambivalent. In the present cohort, triple diagnostics consisting of an incisional biopsy with macroscopic, histologic and microbiotic findings was helpful in timely identification of necrotizing fasciitis.

Abstract
BACKGROUND Necrotizing soft-tissue infection (NSTI) is uncommon but life-threatening. A recent meta-analysis estimated the overall mortality at 23.5%. OBJECTIVE We sought to identify risk factors associated with mortality in a cohort of patients with NSTI in a tertiary care center. METHODS We identified 512 patients with NSTI between 1996 and 2012 in the national hospital database Program for Medicalization of Information Systems and examined risk factors of mortality with NSTI by univariate and multivariate analysis. RESULTS We included 109 patients with a confirmed diagnosis of NSTI; 31 (28%) died at a median follow-up of 274 days (range 2-6135 days). On multivariate analysis, independent risk factors of mortality were age older than 75 years (hazard ratio [HR] 4.4, 95% confidence interval [CI] 1.8-10.3), multifocal NSTI (HR 5.9, 95% CI 1.9-18.5), severe peripheral vascular disease (HR 5.1, 95% CI 1.5-17.0), hospital-acquired infection (HR 3.9, 95% CI 1.4-10.7), severe sepsis (HR 7.4, 95% CI 1.7-33.1), and septic shock on hospital admission (HR 13.9, 95% CI 3.8-50.4). LIMITATIONS This was a retrospective cohort, which disallows a precise record of the delay between diagnosis and surgery. CONCLUSION Our findings for this robust cohort of patients with a definite diagnosis of NSTI could help clinicians stratify NSTI severity at clinical course onset.

Abstract
BACKGROUND Our study sought to identify independent risk factors predisposing patients with necrotizing soft tissue infections (NSTIs) to mortality from among laboratory values, demographic data, and microbiologic findings in a small population. To this end, a retrospective review was conducted of the medical records of all patients with NSTI who had been treated at our institution from 2003 to 2012 (n=134). METHODS Baseline demographics and comorbidities, clinical and laboratory values, hospital course, and the microbiologic characteristics of surgical incision cultures were recorded. Each variable was tested for association with survival status and all associated variables with p<0.15 were included in a logistic regression model to seek factors associated independently with mortality. RESULTS Surprisingly, no demographic or pre-existing condition proved to be a predictor of mortality. Two laboratory values had an inverse correlation to mortality: High C-reactive protein (CRP) and highest recorded CRP. Of surgical incisions that grew bacteria in culture, 33.6% were polymicrobial. Mortality rates were highest with Enterococcus-containing polymicrobial infections (50%), followed by those containing Pseudomonas (40%), and Streptococcus spp. (27%). Understanding why so many studies across the literature, now including our own, find such disparate results for correlation of NSTI mortality with patient data may lie in the fundamentally dynamic nature of the organisms involved. CONCLUSIONS This study suggests that no single factor present on admission is a robust predictor of outcome; it is likely that survival in NSTI is predicated upon a complex interaction of multiple host and microbial factors that do not lend themselves to reduction into a simple formula. It is also abundantly clear that the well-established principles of NSTI surgery should continue to be followed in all cases, with an emphasis on early debridement, irrespective of apparent severity of initial presentation.

Abstract
Necrotizing fasciitis (NF) is a rare mono-/polymicrobial skin infection that spreads to underlying tissues. NF is quickly progressing and leads to life threatening situations. Immediate surgical debridement together with i.v. antibiotic administration is required to avoid fatal outcome. Early diagnosis is often delayed due to underestimation or confusion with cellulitis. We now compared the initial clinical and laboratory presentation of NF and cellulitis in detail to assess if a typical pattern can be identified that aids timely diagnosis of NF and avoidance of fatal outcome. 138 different clinical and laboratory features of 29 NF patients were compared to those of 59 age- and gender matched patients with severe erysipelas requiring a subsequent hospitalization time of ≥10 days. Differences in clinical presentation were not obvious; however, NF patients suffered significantly more often from strong pain. NF patients exhibited dramatically elevated CRP levels (5-fold, p>0.001). The overall laboratory risk indicator for necrotizing fasciitis (LRINEC) score was significantly higher in NF patients as compared to cellulitis. However, a modification of the score (alteration of laboratory parameters, addition of clinical parameters) led to a clear improvement of the score with a higher positive predictive value without losing specificity. In summary, clinical differentiation of NF from cellulitis appears to be hard. ‘Pain out of proportion’ may be an early sign for NF. An improvement of the LRINEC score emphasizing only relevant laboratory and clinical findings as suggested may aid the early diagnosis of NF in the future leading to improvement of disease outcome by enabling rapid adequate therapy.

Abstract
Background Necrotizing fasciitis (NF) is a life-threatening infection of skin and fascia. Its progress is extremely fast, with extensive necrosis. Delay in treatment, with subsequent huge soft tissue loss and associated severe sepsis, remains a major cause of death in the management of NF. Objective The aim of this study was to explore clinical characteristics that may be used to predict severe sepsis in patients with NF, in the context of routine clinical practice in northern Thailand. Methods A retrospective observational cohort study was conducted. The patient cohort in this study consisted of all patients who were diagnosed with NF by surgical or pathological confirmation. The follow-up period started with the admission date and ended with the discharge date. The clinical variables were collected from patients registered at three provincial hospitals in northern Thailand from 2009 to 2012. The clinical predictors for severe sepsis were analyzed using multivariable risk regression. Results A total of 1,452 patients were diagnosed with NF, either with severe sepsis (n=237 [16.3%]) or without severe sepsis (n=1,215 [83.7%]). From the multivariable analysis, female sex (relative risk [RR] =1.51; 95% confidence interval [CI] =1.04–2.20), diabetes mellitus (RR =1.40; 95% CI =1.25–1.58), chronic heart disease (RR =1.31; 95% CI =1.15–1.49), hemorrhagic bleb (RR =1.47; 95% CI =1.32–1.63), skin necrosis (RR =1.45; 95% CI =1.34–1.57), and serum protein <6 g/dL (RR =2.67; 95% CI =1.60–4.47) were all predictive factors for severe sepsis. Conclusion The clinical predictors for severe sepsis in patients with suspicion of NF included female sex, diabetes mellitus, chronic heart disease, hemorrhagic bleb, skin necrosis, and serum protein <6 d/dL. The risk ratio was much higher in patients with total protein less than 6 g/dL, which is associated with malnutrition. Therefore, provision of sufficient nutritional support and close monitoring for these clinical predictors may be beneficial to reduce morbidity and mortality.

Abstract
BACKGROUND Necrotizing skin and soft tissue infections (NSTI) form a group of aggressive diseases that require radical debridement for infection control. Simultaneously, a high-dose broad spectrum antibiotic regimen needs to be initiated with control of septic complications in the intensive care setting. The aim of this work is to analyze the efficacy and safety of tigecycline in a subpopulation of hospitalized, severely ill surgical NSTI patients who were documented in a large multicenter non-interventional study on tigecycline use in routine clinical practice. METHODS A total of 1,025 patients with severe infections including complicated skin and soft-tissue infections (cSSTI, n=163; 15,9%) were enrolled in a prospective multi-center non-interventional study. Patients were to receive an initial intravenous dose of 100 mg tigecycline, followed by 50 mg twice daily. Prospectively documented parameters included clinical findings, APACHE II score, microbiological and standard laboratory assessments, surgical measures, and clinical outcomes including adverse events. RESULTS Of 163 patients were treated for cSSTI, with the largest subgroup being NSTI patients (n=50, 30.7% of all cSSTI, mean age 61 y, median APACHE II score 20). Forty-eight NSTI patients (96%) had at least one comorbidity. In 80% of patients, the treatment was started after previous antibiotic treatment had failed and in 34% resistant pathogens were isolated (28% methicillin resistant Staphyloccocus aureus [MRSA], 4% extended-spectrum-beta-lactamase (ESBL)-producing bacteria, and 2% vancomycin-resistant Enterococci (VRE). Tigecycline was administered as a single agent in 32 patients; 17 received combination regimens. Data from one patient were not reported. Rates of clinical cure or improvement with tigecycline treatment were 90.2%. Two patients (4%) had drug related adverse events (one thrombocytopenia and one fever/chills); 10 patients (20%) died. CONCLUSIONS Tigecycline alone or in combination therapy was an effective and safe antibiotic treatment in critically ill and antimicrobially pre-treated patients with NSTI frequently caused by resistant pathogens.

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
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.
