Abstract
Background Necrotising fasciitis (NF) is a fulminant soft tissue infection that requires timely diagnosis, urgent surgical debridement, and appropriate antimicrobial therapy. The choice of empiric antimicrobial therapy depends on the microorganisms cultured and the antimicrobial resistance profile of the institution. Necrotising fasciitis has not been studied in our setting. Objectives The aim of the study was to audit the microbiological profile of NF and antimicrobial susceptibility profile. Method This was a retrospective study in a secondary level hospital from the period of 2014-2020. The patients' demographic data, clinical features, location of infection, comorbidities, laboratory and microbiological profiles were analysed. Results There were 53 patients during 2014-2020 with median age of 45.5 (38.5-56.0) years. The majority of the patients were males (35 [66.04%]), had no comorbidities (25 [47.17%]), and the lower limb was the most common anatomic site (17 [32.08%]). Type II (monomicrobial) NF was the predominant type (31 [58.49%]). Staphylococcus aureus was the most prevalent Gram-positive bacteria (18 [38%]) and Escherichia coli, the main species isolated in the Gram-negative bacteria (14 [36%]) with susceptibility to cloxacillin (94%) and amoxicillin and/or clavulanic acid (92%), respectively. Conclusion Staphylococcus aureus and Escherichia coli were the most common bacteria with low rate of antimicrobial resistance. Amoxicillin and/or clavulanic acid and an adjunctive clindamycin are appropriate antimicrobial therapy for empiric treatment for NF in our setting. Contribution Amoxicillin and/or clavulanic acid and an adjunctive clindamycin can be used as an empiric treatment for NF.

Abstract
PURPOSE OF REVIEW The aim of this review is to discuss the latest evidence of epidemiology, diagnostic methods, and treatment of necrotizing soft tissue infections (NSTIs) with a particular focus on necrotizing fasciitis (NF). RECENT FINDINGS NSTIs have been historically referred to as NF but encompass a broader range of infections, with variable rates ranging from 0.86 to 32.64 per 100 000 person-years, influenced by factors such as climate and seasonal variations. They have diverse microbiological profiles categorized into different types based on the involved pathogens, including polymicrobial or monomicrobial infections caused by organisms such as group A streptococcus (GAS), Staphylococcus aureus , some Gram-negative pathogens, and filamentous fungi following trauma and natural disasters. Diagnosis relies on clinical symptoms and signs, laboratory markers, and imaging. However, the gold standard for diagnosis remains intraoperative tissue culture. Treatment involves repeated surgical debridement of necrotic tissues in addition to intravenous antibiotics. Adjuvant therapies with intravenous immunoglobulin (IVIG) and hyperbaric oxygen therapy (HBOT) might have a role. Soft tissue reconstruction may be necessary following surgery. SUMMARY Prompt diagnosis and proper medical and surgical management of NSTI will improve outcomes.

Abstract
ABSTRACT Background : Necrotizing soft-tissue infections (NSTIs) present a surgical emergency of increasing incidence, which is often misdiagnosed and associated with substantial mortality and morbidity. A retrospective multicenter (11 hospitals) cohort study was initiated to identify the early predictors of misdiagnosis, mortality, and morbidity (skin defect size and amputation). Methods : Patients of all ages who presented with symptoms and were admitted for acute treatment of NSTIs between January 2013 and December 2017 were included. Generalized estimating equation analysis was used to identify early predictors (available before or during the first debridement surgery), with a significance level of P < 0.05. Results : The median age of the cohort (N = 216) was 59.5 (interquartile range = 23.6) years, of which 138 patients (63.9%) were male. Necrotizing soft-tissue infections most frequently originated in the legs (31.0%) and anogenital area (30.5%). More than half of the patients (n = 114, 54.3%) were initially misdiagnosed. Thirty-day mortality was 22.9%. Amputation of an extremity was performed in 26 patients (12.5%). Misdiagnosis was more likely in patients with a higher Charlson Comorbidity Index (β = 0.20, P = 0.001), and less likely when symptoms started in the anogenital area (β = -1.20, P = 0.003). Besides the established risk factors for mortality (septic shock and age), misdiagnosis was identified as an independent predictor of 30-day mortality (β = 1.03, P = 0.01). The strongest predictors of the final skin defect size were septic shock (β = 2.88, P < 0.001) and a skin-sparing approach to debridement (β = -1.79, P = 0.002). Conclusion : Recognition of the disease is essential for the survival of patients affected by NSTI, as is adequate treatment of septic shock. The application of a skin-sparing approach to surgical debridement may decrease morbidity.

Abstract
This case series reviews the management of 2 patients who developed a rare, aggressive soft tissue infection, necrotizing fasciitis treated with a synthetic polyurethane dermal regenerative template, Biodegradable Temporizing Matrix (NovoSorb BTM) in conjunction with an off-label use of RECELL device applying autologous skin cell suspension and a split-thickness skin graft for reconstruction. The clinical relevance describes a non-traditional patient's course of treatment and clinical outcome using BTM and RECELL for necrotizing fasciitis. The 2 patients survived with acceptable outcomes and timely healing despite a high chance of mortality and likely amputation secondary to the extensive surface area and anatomical location of the infection.

Abstract
PURPOSE To assess the diagnostic contribution of different imaging studies to diagnose necrotizing soft tissue infections (NSTIs) and the time to surgery in relation to imaging with the hypothesis that imaging studies may lead to significant delays without being able to sufficiently dismiss or confirm the diagnosis since a NSTI is a surgical diagnosis. METHODS A retrospective multicenter cohort study of all NSTI patients between 2010 and 2020 was conducted. The primary outcome was the number of cases in which imaging contributed to or led to change in treatment. The secondary outcomes were time to treatment determined by the time from presentation to surgery and patient outcomes (amputation, intensive care unit (ICU) admission, length of ICU stay, hospital stay, and mortality). RESULTS A total of 181 eligible NSTI patients were included. The overall mortality was 21% (n = 38). Ninety-eight patients (53%) received imaging in the diagnostic workup. In patients with a clinical suspicion of a NSTI, 81% (n = 85) went directly to the operating room and 19% (n = 20) underwent imaging before surgery; imaging was contributing in only 15% (n = 3) by ruling out or determining underlying causes. In patients without a clinical suspicion of a NSTI, the diagnosis of NSTI was considered in 35% and only after imaging was obtained. CONCLUSION In patients with clinically evident NSTIs, there is no role for standard imaging workup unless it is used to examine underlying diseases (e.g., diverticulitis, pancreatitis). In atypical presenting NSTIs, CT or MRI scans provided the most useful information. To prevent unnecessary imaging and radiation and not delay treatment, the decision to perform imaging studies in patients with a clinical suspicion of a NSTI must be made extremely careful.

Abstract
Background: Because mortality and amputation rates are declining for necrotizing soft tissue infections (NSTIs), this study aimed to assesses the self-reported one-year quality of life (QoL) of severely ill patients with NSTI who survived beyond the intensive care unit (ICU). Patients and Methods: A retrospective cohort study of patients with NSTI admitted to the ICU between 2010 and 2019 was conducted. A year after ICU discharge, QoL was assessed using the three-level EuroQol five-dimensions (EQ-5D-3L) questionnaire, Impact of Event Scale-Revised (IES-R) questionnaires, and pain scales. Furthermore, willingness to undergo ICU admission again if needed was reviewed. Results: Twenty-nine (of 38) patients with NSTI survived their hospitalization (76%). During the one-year follow-up, three patients died (8%; one-year survival 68%). Nineteen patients filled out the questionnaires (73%). The median EQ-5D-3L index score was 0.775 (interquartile range [IQR], 0.687-0.843). The domains reported most to cause impairment were "usual activity" and "pain/discomfort." Patients had a median pain score of five (of 10; IQR, 1-6) and two patients (15%; of 13) scored "clinical concern for PTSD.". Eighty-five percent of the patients would undergo the ICU treatment again if needed. Conclusions: The one-year QoL of ICU-admitted patients with NSTI varies widely, however, the overall QoL and one-year survival was similar to other ICU patients who underwent acute surgery and the QoL was slightly lower than the general ICU population. Most patients experience problems with daily activity and pain, but this does not mean that patients with NSTI automatically had poor self-reported quality of life or unwillingness to undergo ICU treatment again if needed.

Abstract
Patients with extensive and complex wounds due to Necrotizing Soft-Tissue Infections (NSTI) may be referred to a burn center. This study describes the characteristics, outcomes, as well as diagnostic challenges of these patients. Patients admitted to three hospitals with a burn center for the treatment of NSTI in a 5-year period were included. Eighty patients (median age 54 years, 60% male) were identified, of whom 30 (38%) were referred by other centers, usually after survival of the initial septic phase. Those referred from other centers, compared to those primarily admitted to the study hospitals, were more likely to have group A streptococcal involvement (62% vs 35%, p = .02), larger wounds (median 7% vs 2% total body surface area, p < .001), and a longer length of stay (median 49 vs 22 days, p < .001). Despite a high incidence of septic shock (50%), the mortality rate was low (12%) for those primarily admitted. Approximately half (53%) of the patients were initially misdiagnosed upon presentation, which was associated with delay to first surgery (16 hours vs 4 hours, p < .001). Those initially misdiagnosed had more (severe) comorbidities, and less frequently reported pain or blue livid discoloration of the skin. This study underlines the burn centers' function as referral centers for extensively affected patients with NSTI. Besides the unique wound and reconstructive expertise, the low mortality rate indicates these centers provide adequate acute care as well. A major remaining challenge remains recognition of the disease upon presentation. Future studies in which factors associated with misdiagnosis are explored are needed.

Abstract
Reactivation of herpes zoster ophthalmicus (HZO) can present as corneal involvement without any precedent neuralgia or characteristic herpetic rash. This form of HZO can be the first manifestation of reactivation of varicella zoster virus and can masquerade as peripheral ulcerative keratitis. A 45-year-old male treated for necrotizing fasciitis (NF) one month back presented with painful diminution of vision in the right eye (RE) for two weeks without any associated vesicular rash or neuralgia. On examination, best-corrected visual acuity in RE was 2/60 with non-marginal upper lid defect, and multiple linear contracture scars involving the upper lid, right temple, and preauricular region. There were associated peripheral corneal ring infiltrates, disc-shaped central stromal edema, and reduced corneal sensation. The patient had a history of chicken pox in childhood and was recently diagnosed with seropositive rheumatoid arthritis (RA). Though corneal scrapings were negative on Tzanck smear, a presumptive clinical diagnosis of herpetic disciform keratitis was made, and the patient was started on oral and topical acyclovir with steroids. This was confirmed with improving clinical course and detection of herpes zoster DNA on polymerase chain reaction from corneal scrapings. Lid reconstruction for associated lid defect was performed using paramedian forehead flap, which was remodeled at 16 weeks. Our case, a seropositive RA patient, had reactivation of varicella zoster manifesting as peripheral serpiginous and disciform keratitis activated after NF. There are a few case reports of periorbital NF following HZO in immunocompromised patients. However, till date, no case of HZO occurring after periorbital NF has been reported. Also, in our case, reactivation of HZO presented as disciform and serpiginous keratitis without any precedent herpetic rash or neuralgia.

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: Necrotizing fasciitis (NF) is a potentially fatal soft tissue infection. Four types of pathogens can be distinguished in the pathogen spectrum, although there are strong regional differences with regard to the most common pathogens. Patients and Methods: All cases of NF between 2003 and 2021 with an identified causative agent were analyzed retrospectively. The cases were divided into three groups: polymicrobial, gram-positive and gram-negative. Demographic factors, localization of infection, inflammatory parameters, and clinical outcome were compared between the three groups. Results: A total of 95 cases were analyzed, 41% of which were caused by multiple pathogens. A gram-positive pathogen was reported in 40% of cases and a gram-negative pathogen in 19%. There were significant differences between the three groups with respect to age (with patients in the gram-negative group being on average the oldest) and intensive care unit admissions (which was most frequent in the polymicrobial group). Conclusions: The pathogen spectrum of NF has rarely been studied in a large patient population. Gram-positive pathogens account for the majority of monomicrobial infections in our study. Nevertheless, we recommend calculated broad-spectrum antibiotic therapy given the high number of polymicrobial infections and gram-negative infections. Gram-negative infections may be associated with increased mortality, elevated procalcitonin levels, and are relatively frequent in NF of the lower extremities.
