RESUMEN
<b><br>Introduction:</b> Necrotizing fasciitis (NF) is an expeditiously escalating inflammatory infection of the fascia, with secondary necrosis of the subcutaneous tissues. To aid diagnosis, the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) scoring system was devised to stratify the likelihood of infection in patients on presentation.</br> <b><br>Aim:</b> The study aimed to investigate and quantify the relationships between the LRINEC scoring system and the outcomes such as the need for amputation, length of hospital stay, and mortality in patients with necrotizing fasciitis.</br> <b><br>Material and methods:</b> A total number of 90 patients were admitted with a provisional diagnosis of necrotizing fasciitis. LRINEC score was calculated for each case based on six laboratory variables at the time of presentation. Enrolled patients were divided into three groups on the basis of the LRINEC score. The differences in mortality, length of hospitalization, number of debridement procedures, and need for amputation between these groups were compared.</br> <b><br>Results:</b> Increasing age, male gender, and DM have a poor prognosis in necrotizing fasciitis patients. The amputation and mortality rates are better correlated with higher LRINEC scores.</br> <b><br>Conclusions:</b> The LRINEC score helps in stratifying the patients into three risk categories (low risk, moderate risk, and high risk) according to the severity in a much more organized way, and thus the appropriate management like surgical debridement can be introduced on time. LRINEC score is a robust index that is capable of detecting early cases of necrotizing fasciitis and is simple enough for routine use. It is a simplified bedside diagnostic tool for early diagnosis and prediction of outcomes in patients with necrotizing fasciitis.</br>.

Necrotizing fasciitis (NF) is a rare, dangerous, potentially fatal infectious disease of soft tissue. The treatment consists of antibiotic therapy, surgical debridement and subsequent reconstruction. Hyperbaric oxygen (HBO) therapy has been applied in NF patients recently, so our aim was to gather the findings and outcomes for HBO therapy. A PubMed and Google Scholar literature search was conducted regarding the effect of HBO therapy in patients with NF following key words: 'necrotizing fasciitis' AND 'maxillofacial region' OR 'head and neck' AND 'hyperbaric oxygen' OR 'HBO'. A total of 3333 studies have been identified, of which only 16 articles met the inclusion criteria of this review. A conclusion was made, that aggressive combinations of antibiotics and surgical debridement followed by incorporation of HBO therapy, as an adjuvant treatment, in patients with NF and in company by immunoglobulin therapy are showing promising results. In addition, multi-centric studies should be in consideration for further research.

INTRODUCTION: Acute epiglottitis is not uncommon and it can cause high mortality due to airway obstruction. Acute epiglottitis complicated with cervical necrotizing fasciitis has rarely been reported, and it is also a life-threatening disease with a fatality rate of 7% to 50%. PATIENT CONCERNS: A 64-year-old woman presented to our hospital with chief complaints of sore throat and cervical swelling, long with foreign body sensation and hoarseness. Endoscopic laryngoscopy showed erythematous and swollen epiglottis with purulent secretions on the surface. Computed tomography (CT) scan showed swollen epiglottis and swelling of the neck with air- and fluid-containing necrotizing tissue. DIAGNOSES: The diagnosis was acute epiglottitis and abscess complicated with cervical necrotizing fasciitis. INTERVENTIONS: With the patient in awake condition, airway access was established by performing intubation with adjunctive use of gum elastic bougie, followed by surgical debridement under general anesthesia; a flap was used for skin coverage and intravenous piperacillin-tazobactam was administered. OUTCOMES: The patient was discharged without complications. CONCLUSION: Gum elastic bougie is a usable tool in difficult intubation. Adequate pre-anesthesia evaluation, patient sedation, and gentle manipulation assured the intubation success in this case.

HISTORY AND CLINICAL FINDINGS: We report on a 34-year-old female patient and a 50-year-old male patient, both of whom were admitted to our emergency department with severe septic conditions. MEDICAL EXAMINATIONS: Both patients were resuscitated and exhibited clinical as well as laboratory evidence of a severe bacterial infection. DIAGNOSIS: Both patients had an invasive infection with Group A Streptococcus. The female patient had a Streptococcal sepsis with severe pneumonia, while the male patient had a Streptococcus-induced necrotizing fasciitis of the upper extremity. THERAPY AND COURSE: While the female patient unfortunately died in the emergency department`s resuscitation room despite all intensive medical treatments, the male patient survived after prompt surgical therapy and an extended stay in the intensive care unit. CONCLUSION: Patients with invasive infections caused by Group A Streptococcus can deteriorate rapidly clinically. Prompt diagnosis and initiation of often interdisciplinary treatment are important. Nevertheless, these conditions can be fatal.

OBJECTIVES: Necrotizing soft-tissue infection and necrotizing fasciitis of the upper limb are infrequent. Studies are rare, and often include other anatomical regions. The specificities and particularities of this pathology are not well known. The aim of this study was to report diagnosis and treatment aspects. METHODS: A retrospective study was conducted over 10 years on every patient treated for necrotizing fasciitis of the upper limb with clinical, bacteriological and histological confirmation. One hundred ninety-eight items were extracted for each patient concerning clinical, biological, radiological and therapeutic data. RESULTS: During 10 years, 24 patients were diagnosed with necrotizing fasciitis of the upper limb: 18 males, 6 females; mean age, 59.9 years; mean body mass index, 25. Local erythema, pain and fever were the most frequent symptoms. Skin necrosis was present in fewer than 40% of patients. Sixteen cases (66.6%) had prior skin lesions and/or an entry point on the limb. Ten had non-steroidal anti-inflammatory drug prescription before acute symptom onset (42%), requiring intensive care unit admission. Treatment comprised surgical resection, resuscitative measures, antibiotic therapy and reconstructive surgery. Seven patients (30.4%) had 1 session of cutaneous excision, and the others had more than 2. Microbiological analysis found mono-microbial beta-hemolytic group A streptococci (BHGAS) infection in 14 patients (58.4%). Antibiotics were prescribed in 91% of cases before surgery, and in 100% after. The most frequently prescribed substance was clindamycin (18 patients, 75%). Ten patients (42%) stayed in the intensive care unit during treatment. Seventeen patients (70.8%) had thin skin graft reconstruction, including 50% with dermal substitute. Five patients (20.8%) had partial upper limb amputation. Two patients (8.3%) died in the 30 days following diagnosis. CONCLUSIONS: The death rate in necrotizing fasciitis of the upper limb was rather low but the amputation rate was higher than in other locations. This study shows the specific clinical, biological and treatment features of this rare but serious pathology of the upper limb.

This article aims to provide an overview of common and high-impact medical emergencies that require prompt and effective infectious diseases management. In the described clinical scenarios of malaria, sepsis, necrotizing fasciitis, and meningitis the authors have emphasized the crucial importance of rapid and accurate diagnosis, as well as appropriate treatment from the perspective of infectious diseases. All of these emergencies demand a high degree of clinical suspicion for accurate diagnosis. Some of them also necessitate the involvement of other medical disciplines, such as neurology in the case of meningitis or surgery for necrotizing fasciitis. Additionally, implementing the right empiric antibiotic regimen or, in the case of malaria, antiparasitic treatment is crucial for improving patient outcomes. As patients with these diagnoses may present at any outpatient department, and efficient and quick management is essential, a deep understanding of diagnostic algorithms and potential pitfalls is of the utmost importance.

Introduction: There are inconsistencies in outcome reporting for patients with necrotising soft tissue infections (NSTI). The aim of this study was to evaluate reported outcome measures in NSTI literature that could inform a core outcome set (COS) such as could be used in a study of hyperbaric oxygen in this indication. Methods: A systematic review of all NSTI literature identified from Cochrane, Ovid MEDLINE and Scopus databases as well as grey literature sources OpenGrey and the New York Academy of Medicine databases which met inclusion criteria and were published between 2010 and 2020 was performed. Studies were included if they reported on > 5 cases and presented clinical endpoints, patient related outcomes, or resource utilisation in NSTI patients. Studies did not have to include intervention. Two independent researchers then extracted reported outcome measures. Similar outcomes were grouped and classified into domains to produce a structured inventory. An attempt was made to identify trends in outcome measures over time and by study design. Results: Three hundred and seventy-five studies were identified and included a total of 311 outcome measures. Forty eight percent (150/311) of outcome measures were reported by two or more studies. The four most frequently reported outcome measures were mortality without time specified, length of hospital stay, amputation performed, and number of debridements, reported in 298 (79.5%), 260 (69.3%), 156 (41.6%) and 151 (40.3%) studies respectively. Mortality outcomes were reported in 23 different ways. Randomised controlled trials (RCTs) were more likely to report 28-day mortality or 90-day mortality. The second most frequent amputation related outcome was level of amputation, reported in 7.5% (28/375) of studies. The most commonly reported patient-centred outcome was the SF-36 which was reported in 1.6% (6/375) of all studies and in 2/10 RCTs. Conclusions: There was wide variance in outcome measures in NSTI studies, further highlighting the need for a COS.

Hyperbaric oxygen therapy consists of breathing 100% oxygen continuously or intermittently in a chamber at a pressure equal to or greater than 1.4 absolute atmospheres. Indicated for the emergency treatment of carbon monoxide poisoning and other medical-surgical pathologies such as gas embolism or necrotizing soft-tissue infections, various studies have shown a beneficial effect of hyperbaric oxygen therapy in certain ocular pathologies, notably of microcirculatory origin, such as central retinal artery occlusion or macular edema linked to retinal vein occlusions. In addition, hyperbaric oxygen might represent an alternative treatment for ocular quinine toxicity and might also be useful as an adjuvant to surgery and antibiotics in cases of periorbital necrotizing fasciitis. On the other hand, oxygen in high concentrations has toxic ocular effects due to the production of reactive oxygen derivatives.

PEDIATRIC NECROTIZING SOFT-TISSUE INFECTIONS. Necrotizing soft-tissue infections (NSTI) include necrotizing forms of fasciitis, myositis, and cellulitis. In children, these are extremely rare conditions with an estimated annual incidence of less than 0.1/100,000 patients aged 0-18 years in France. Nevertheless, the evolution can be very serious (6% mortality, higher than the mortality observed in paediatric intensive care units [PICU]), whereas the initial local symptoms are poor and can be falsely reassuring. The monitoring of a skin infection must be close in order not to ignore the evolution towards a NSTI. In this case, prompt transfer to a PICU with all the necessary technical facilities and used to the management of these rare conditions must be done. Early initiation of antibiotic treatment and aggressive haemodynamic resuscitation according to the latest Surviving Sepsis Campaign guidelines should be a priority. The paediatric surgeon should be called upon as soon as clinical suspicion arises and participate in the frequent clinical reassessment to determine the optimal time to perform the surgical treatment.
INFECTIONS CUTANÉES NÉCROSANTES DE L'ENFANT. Les infections cutanées nécrosantes comprennent les dermo- hypodermites bactériennes nécrosantes (DHBN) et les fasciites nécrosantes (FN). Chez l'enfant, ce sont des pathologies extrêmement rares, avec une incidence annuelle en France estimée inférieure à 0,1/100 000 patients âgés de 0 à 18 ans. Néanmoins, leur évolution peut être gravissime (mortalité de 6 %, supérieure à la mortalité observée habituellement dans les unités de réanimation pédiatrique [URP]) alors que la symptomatologie locale initiale est pauvre et peut faussement rassurer. La surveillance d'une infection cutanée doit être rapprochée afin de ne pas méconnaître l'évolution vers une DHBN-FN. Dans ce cas, une orientation vers une URP disposant de l'ensemble du plateau technique nécessaire, et surtout habituée à gérer ces situations cliniques, est justifié. L'initiation précoce du traitement antibiotique et la prise en charge hémodynamique agressive en suivant les dernières recommandations de la Surviving Sepsis Campaign doivent être une priorité. Le chirurgien pédiatrique doit être appelé dès la suspicion clinique et participer à la réévaluation pluriquotidienne afin de déterminer le moment optimal pour réaliser le traitement chirurgical.

BACKGROUND: The role of hyperbaric oxygen therapy (HBOT) in necrotizing soft tissue infections (NSTI) is mainly based on small retrospective studies. A previous study using the 1998-2009 National Inpatient Sample (NIS) found HBOT to be associated with decreased mortality in NSTI. Given the argument of advancements in critical care, we aimed to investigate the continued role of HBOT in NSTI. METHODS: The 2012-2020 National Inpatient Sample (NIS) was queried for NSTI admissions who received surgery. 60,481 patients between 2012-2020 were included, 600 (<1%) underwent HBOT. Primary outcome was in-hospital mortality. Secondary outcomes included amputation, hospital length of stay, and costs. A multivariate model was constructed to account for baseline differences in groups. RESULTS: Age, gender, and comorbidities were similar between the two groups. On bivariate comparison, the HBOT group had lower mortality rate (<2% vs 5.9%, p<0.001) and lower amputation rate (11.8% vs 18.3%, p<0.001) however, longer lengths of stay (16.9 days vs 14.6 days, p<0.001) and higher costs ($54,000 vs $46,000, p<0.001). After multivariate analysis, HBOT was associated with decreased mortality (Adjusted Odds Ratio (AOR) 0.22, 95% CI 0.09-0.53, P<0.001) and lower risk of amputation (AOR 0.73, 95% CI 0.55-0.96, P = 0.03). HBO was associated with longer stays by 1.6 days (95% CI 0.4-2.7 days) and increased costs by $7,800 (95% CI $2,200-$13,300), they also had significantly lower risks of non-home discharges (AOR 0.79, 95%CI 0.65-0.96). CONCLUSIONS: After correction for differences, HBOT was associated with decreased mortality, amputations, and non-home discharges in NSTI with the tradeoff of increase to costs and length of stay.

HAND INFECTIONS. Hand and finger infections are very common. They result from the inoculation of a germ through the skin barrier. They can range from simple paronychia to extremely serious necrotizing fasciitis. Certain infections, such as those resulting from bites, have their own specific characteristics, which will determine how they are managed. While management can be medical in the early stages, it is important not to ignore the need for surgical treatment, otherwise serious complications may arise, leading to functional and aesthetic sequelae. Delays in treatment cannot be made up. Any infectious lesion can be potentially serious and must be treated in an appropriate department if there is the slightest doubt.
INFECTIONS DE LA MAIN. Les infections de la main et des doigts sont très fréquentes. Elles résultent de l'inoculation d'un germe à travers la barrière cutanée. Elles vont du simple panaris à la gravissime fasciite nécrosante. Certaines infections, comme celles faisant suite aux morsures, ont des caractéristiques propres dont dépend la prise en charge. Si elle peut être médicale au stade initial, il est important de ne pas méconnaître le moment du traitement chirurgical sous peine de voir survenir des complications graves responsables de séquelles fonctionnelles et esthétiques. Le retard à la prise en charge ne peut être rattrapé. Toute lésion infectieuse peut être potentiellement grave et, au moindre doute, doit être prise en charge dans un service adapté.

Background: A notable improvement in the treatment of necrotizing soft tissue infections (NSTIs) is the development of negative pressure wound therapy (NPWT). Clinicians are still debating whether NPWT is as successful as conventional wet-to-dry dressings at removing bacteria. Recent research has revealed potential oxygen deprivation effects of NPWT in underlying wound tissues, although clinical trials regarding the effects of reduced oxygen on anaerobic bacterial soft tissue infections remain noticeably lacking. Hypothesis: We hypothesized that NPWT-treated patients with NSTIs who were solely infected by anaerobic bacteria would have worse outcomes than those who were infected with other bacterial species. Patients and Methods: Our study included a retrospective examination of the 2008-2022 period of our Acute and Critical Care Surgery database. Patients who had been identified as having necrotizing fasciitis, Fournier gangrene, or gas gangrene and who had their conditions verified by positive wound cultures acquired during the initial debridement and subsequently received NPWT made up the study cohort. Comorbidities, surgical techniques, and clinical results were all covered by the data. Based on their wound infections, patients were divided into two groups: those with exclusively anaerobic NSTIs and those with different bacterial groups (such as polymicrobial and aerobic). Multiple regression, χ2 analysis, and analysis of variance (ANOVA) were among the analytical methods used. Results: One hundred twelve patients with NSTI who had received NPWT comprised the study cohort. Sixteen of these patients (14.3%) had NSTIs that were exclusively anaerobic, whereas the remaining 96 (85.7%) had NSTIs that were mixed aerobic, facultative, or polymicrobial. Between the two groups, there was no difference in the initial wound size. Patients with anaerobic NSTI who underwent NPWT showed a statistically significant increase in the number of debridements (3 [interquartile range {IQR},1-9] vs. 2 [IQR, 1-4]; p = 0.012) and an increased 100-day re-admission rate (37.5% vs. 12.5%; p = 0.012) when compared with patients with non-anaerobic NSTI. The 100-day re-admission rate increased three-fold in NPWT-treated anaerobic NSTIs, according to a logistic regression analysis (odds ratio [OR], 3.63; 95% confidence interval [CI], 1.06-12.44; p = 0.04). Conclusions: In contrast to patients with other bacterial strains, our data show that patients with NSTI treated with NPWT who only have anaerobic bacterial infections have a larger number of debridements and are much more likely to require re-admission within 100 days. We call for additional prospective studies to be conducted to identify additional risk factors and consider alternate treatment options for individuals with exclusively anaerobic NSTIs in light of these findings.

Objective: To analyze the clinical data and to screen the mortality risk factors of necrotizing fasciitis (NF) secondary to intestinal fistulas (NFsIF). Methods: This study was a retrospective observational study. The data of all NFsIF cases who met the inclusion criteria and were admitted into Shandong Provincial Hospital Affiliated to Shandong First Medical University (hereinafter referred to as our unit) from January 2000 to October 2023, and in PubMed, Web of Science, Scopus, China National Knowledge Infrastructure, and Chinese Medical Journal Network databases from its establishment to October 2023 were retrieved and screened. Based on clinical outcomes, the cases were divided into survival group (47 males and 24 females) and death group (16 males and 7 females), and the mortality rate was calculated. Clinical data of patients in the two groups including age, underlying diseases (most related to NF), symptom duration before presentation, white blood cell count, causes of NF, signs of peritonitis, scope of NF involvement, and intestinal management and wound management measures were compared and analyzed to screen the risk factors of death in 94 patients with NFsIF. Results: A total of 94 valid cases were collected, including 90 patients reported in the literature and 4 patients admitted to our unit, with the mortality rate of patients being 24.5% (23/94). Univariate analysis showed that there were no statistically significant differences in age, underlying diseases, symptom duration before presentation, white blood cell count, causes of NF, signs of peritonitis, scope of NF involvement between patients in the two groups (P>0.05); there were statistically significant differences in intestinal treatment and wound treatment between the two groups (with χ2 values of 17.97 and 8.33, respectively, P<0.05). Multivariate logistic regression analysis showed that both intestinal treatment measures and wound treatments measures were independent risk factors for death in 94 NFsIF patients, among which first-stage colostomy+late-stage reconstruction and negative presssure therapy had higher protective effects (with odds ratios of 0.05 and 0.27, respectively, 95% confidence intervals of 0.01-0.33 and 0.08-0.88, respectively, P<0.05). Conclusions: The mortality risk of patients with NFsIF is high. Based on comprehensive treatments, active intestinal and wound treatment may be the key to avoid death, with first-stage colostomy+late-stage reconstruction and negative pressure therapy having higher protective effects.

BACKGROUND: Necrotizing fasciitis (NF) is a rare but life-threatening condition in which extensive soft tissue destruction can occur very quickly if left untreated. Therefore, timely broad-spectrum antibiotic administration is of prognostic importance in addition to radical surgical debridement. AIM: This study evaluates the cases of NF in our hospital during the last ten years retrospectively with respect to the pathogens involved and their antimicrobial resistance. This approach aims to provide guidance regarding the most targeted initial antibiotic therapy. METHODS: We performed a retrospective microbiological study evaluating pathogen detection and resistance patterns including susceptibility testing of 42 patients with NF. RESULTS: Type 1 NF (polymicrobial infection) occurred in 45% of the patients; 31% presented type 2 NF (monomicrobial infection). The most common pathogens detected were E. coli, staphylococci such as Staphylococcus aureus and Staphylococcus epidermidis, Proteus mirabilis, enterococci, and streptococci such as Streptococcus pyogenes. Twelve percent presented an additional fungus infection (type 4). Ten percent showed no cultivation. Two percent (one patient) presented cocci without specification. CONCLUSION: Most pathogens were sensitive to antibiotics recommended by guidelines. This confirms the targeting accuracy of the guidelines. Further studies are necessary to identify risk factors associated with multidrug resistant infections requiring early vancomycin/meropenem administration.

OBJECTIVE: Necrotizing soft-tissue infection (NSTI) in the head and neck area may develop from odontogenic infections. The aim of this study was to characterize patients with NSTI in the head and neck with odontogenic origin in a well-defined prospectively collected cohort. MATERIAL AND METHODS: Patients with NSTI in the head and neck, hospitalized between 2013 and 2017 at Copenhagen University Hospital and registered in the Scandinavian INFECT database were included. Medical records of identified patients and from the INFECT database were screened for a defined set of data including the primary focus of infection, comorbidities, predisposing factors, clinical and radiographic diagnostics, course of treatment, and treatment outcome. RESULTS: Thirty-five patients with NSTI in the head and neck area were included in the study. A total of 54% had odontogenic origin, primarily from mandibular molars, and 94% had radiographic signs of infectious oral conditions. Overall, comorbidities were reported in 51% with cardiovascular disease being the most prevalent. In 20%, no comorbidities or predisposing conditions could be identified. The overall 30-day mortality rate was 9%. CONCLUSIONS: More than half of NSTI cases in the head and neck region had an odontogenic origin, and special attention should be paid to infections related to mandibular molars.

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 100â000 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.
