Role of SFGSI, microbial culture and qSOFA as predictive factors in determining the survival rate in Fournier Gangrene patient.

OBJECTIVES: To examine the simplified Fournier Gangrene Severe Index Score (SFGSI) and the number of species in culture findings for predicting death in Fournier Gangrene (FG) patients in terms of their predictive power. METHODS: From January 2017 to July 2022, the medical records of individuals undergoing emergency surgery for FG were obtained. A total of 80 patients were examined for clinical data such as age, gender, laboratory parameters, etiology, isolated bacteria, and mortality rate. RESULTS: We identified a statistically significant mean difference between SFGSI (p<0.0001) and quickSOFA (qSOFA) scores (p=0.002) in determining the survival rate of FG patients. The sensitivity and specificity of the SFGSI score in predicting mortality were 90.1% and 88.3% respectively, whereas the sensitivity and specificity of the qSOFA score were 88.2% and 86.2%. E. Coli comprised 56.2% of the bacteria, followed by S. Haemolyticus, S. Aureus, P. Aeruginosa, and K. Pneumoniae. On the basis of bacterial culture results, P. Aeruginosa had the highest fatality rate (100%) followed by S. Aureus (75%), S. Haemolyticus (30%), and E. Coli (20%), in that order. CONCLUSION: The survival rate of FG patients can be predicted using the sensitivity and specificity of the SFGSI and qSOFA scores together. P. Aeruginosa-infected patients have the greatest mortality rate (100%) compared to the other groups.

A Cross-Sectional Analysis of Pediatric Necrotizing Soft Tissue Infection Cases and Racial Disparities From the 2016 to 2020 National Inpatient Sample.

INTRODUCTION: The incidence, treatment, and outcomes of necrotizing soft tissue infections (NSTIs) and associated racial disparities have been described in adults, but research in the pediatric population is limited. The purpose of this study is to provide a nationally representative characterization of pediatric NSTI and determine the presence of any racial disparities. METHODS: The National Inpatient Sample was analyzed from 2016 through 2020. Patients aged less than 20 y with a diagnosis of necrotizing fasciitis, Fournier's gangrene, or gas gangrene (based on International Classification of Diseases, Tenth Revision, Clinical Modification codes) were included for analysis. RESULTS: A total of 355 patients were identified. Black and Hispanic patients accounted for the most admissions in 2016 and 2018, respectively (P = 0.024). Compared to White patients, more Black patients were insured by Medicaid (P = 0.037) and were in the first zip code-based income quartile (P = 0.005). The leading infection overall was necrotizing fasciitis and most patients (81.7%) underwent a surgical procedure by the first calendar day after admission. Although the proportion of Black patients undergoing subcutaneous tissue and fascia excisions was more than that of White patients (P = 0.005), there were no significant differences by race in the time to first procedure, the total number of procedures, or number of postoperative complications. Our amputation and mortality rates were low and unreportable, but there were no differences by race. CONCLUSIONS: NSTI is rare in the pediatric population and mortality is low. Black patients are disproportionately diagnosed, but these disparities do not extend to disease treatment or outcomes.

Negative Pressure Wound Therapy With and Without Instillation in Necrotizing Soft Tissue Infections.

Background: Necrotizing soft tissue infections (NSTIs) are rare but deadly infections that require early and often extensive surgical debridement. After debridement, patients frequently have substantial morbidity because of large, open wounds. Hypothesis: Negative pressure wound therapy with instillation (NPWTi) results in higher wound closure rates compared with traditional negative pressure wound therapy (NPWT) or wet to dry dressings (moist wound care dressing). Patients and Methods: A prospectively maintained Acute and Critical Care Surgery database spanning 2008-2018 was queried for patients with a diagnosis of necrotizing fasciitis, Fournier gangrene, or gas gangrene. Data were collected on patient comorbidities, operative management, and clinical outcomes. Patients were stratified by use of moist wound care dressing, traditional NPWT, or NPWTi. Data were analyzed using analysis of variance (ANOVA), χ2, and logistic regression. Results: During the 10-year study period, patients were treated for NSTI; 173 were managed with moist wound care dressing, 150 with NPWT, and 48 with NPWTi. Patients were similar in terms of demographics, body mass index (BMI), diabetes mellitus, and smoking rates. Overall, complication rates were not substantially different, but mortality was higher in the moist wound care dressing group (16.2% vs. 10.7% NPWT vs. 2.1% NPWTi; p = 0.02). In the moist wound care dressing group, 81.5% of patients had an open wound at discharge compared with 52.7% of the NPWT group and only 14.6% of the NPWTi group (p < 0.001). On multivariable regression, NPWTi was associated with closure rates five times higher than the NPWT group (odds ratio [OR], 5.28; 95% confidence interval [CI], 2.40-11.61; p < 0.001) after controlling for smoking status, intravenous drug use, number of operations, and involvement of the most common region of the body. Conclusions: Negative pressure wound therapy with instillation is associated with higher rates of wound closure without increasing complication rates in patients with NSTI compared with traditional NPWT or moist wound care dressing. Although prospective studies are needed, this indicates the potential to improve patient quality of life through reduced pain and outpatient home health needs.

[A New Case of Fournier's Gangrene Caused by Actinotignum schaalii]. / Actinotignum schaalii'nin Etken Oldugu Yeni Bir Fournier Gangreni Olgusu.

Actinotignum schaalii (formerly known as Actinobaculum schaalii) is an anaerobic or facultative anaerobic gram-positive bacillus that can be found commensally in the urogenital region. It can be overlooked because it grows slowly and is difficult to identify with classical microbiology laboratory techniques. Colonies become visible after 48-72 hours of incubation on blood agar in anaerobic or CO2-rich media. While it typically causes urinary tract infection in older individuals, cases of bacteremia, vertebral osteomyelitis, endocarditis and cellulitis have been reported. Fournier's gangrene caused by A.schaalii has been reported very rarely so far. Fournier's gangrene has been defined as necrotizing fasciitis of the external genitalia, perineal and perianal region. Diabetes, immunosuppression, peripheral vascular disease, urethral anomalies, chronic alcoholism and smoking are important predisposing factors. In addition, approximately 25% of the cases have no known or identifiable etiology. The bacteria causing the infection may originate from skin, urogenital or intestinal microbiota. In this case report, a new case of Fournier's gangrene caused by A.schaalii was presented. A 65-year-old male patient admitted to the emergency department with the complaints of pain, swelling, redness in the left testis and also nausea, vomiting and chills that started three days ago. Physical examination revealed increased diameter of the scrotum, intense hyperemia of the skin and foci of necrosis. It was learned that the patient had no known chronic disease other than benign prostatic hyperplasia. The patient reported smoking of 25 packs of cigarettes per year. Routine laboratory tests revealed leukocyte= 32.41 x 109/L, neutrophil= 89.9%, procalcitonin= 1.62 ug/L, CRP= 265.07 mg/L and the patient was operated with the diagnosis of Fournier's gangrene. Gram staining of the abscess specimen obtained during the operation showed gram-positive bacilli both inside and outside the leukocytes. After 24 hours, grampositive bacilli were detected in the Gram staining of thin, transparent/gray colonies grown on 5% sheep blood and chocolate agar. The isolate was identified as A.schaalii by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) VITEK® MS (bioMérieux, France) microbial identification system. VITEK®2 ID ANC (bioMérieux, France) bacterial identification card was also used for comparison but the bacteria could be identified. As a result of the sequence analysis performed for confirmation, it was shown to be 100% homologous with Actinobaculum schaalii (GenBank accession no: FJ711193.1). For susceptibility tests, 5% sheep blood Schaedler agar was used and incubated in anaerobic environment. According to the minimal inhibitory concentration (MIC) results evaluated after 48 hours, penicillin was found to be 0.032 mg/L, clindamycin 0.125 mg/L, ciprofloxacin 0.19 mg/L, ceftazidime 4 mg/L, and amoxicillin 0.19 mg/L. The primary cause that initiated the infection in the case could not be identified, but it was thought that the presence of prostatic hyperplasia and smoking history may have contributed to the occurence or the progress of the disease. It is noteworthy that the ciprofloxacin MIC result was quite low compared to other studies. In addition, this study revealed the value of MALDI-TOF MS based methods in identification. In conclusion, it is thought that a significant proportion of A.schaalii infections may be overlooked due to the difficulty in growth and identification. Increasing the diagnostic power of clinical microbiology laboratories for poorly identified bacteria and renewing the databases of commercial identification systems are important for the early and accurate diagnosis and treatment of serious infections that may occur with such agents.

Fournier's gangrene of the penis complicating both COVID-19- and Mpox-related genital ulceration - A case report.

Fournier's gangrene is a rare, rapidly progressive, fulminant form of infective necrotising fasciitis of the genital, perianal and perineal regions. We present a case of Fournier's gangrene of the penis complicating acute genital ulceration and recurrent paraphimosis that was secondary to contemporaneous COVID-19 and Mpox infection in an otherwise healthy 41-year-old man. It is important for clinicians to be aware of Fournier's gangrene, as early detection remains the cornerstone of effective tissue and indeed life conserving management.

Fournier's gangrene and fecal diversion. When, in which patients, and what type should I perform?

INTRODUCTION: Fournier's gangrene (FG) is a necrotizing fasciitis affecting the perineum and urogenital tissue. The mortality rate is high although early detection and aggressive debridement can reduce mortality by up to 16%. The prevalence of sequelae is very high and a colostomy is often necessary to control the perineal wound. MATERIAL AND METHODS: A retrospective study was carried out to recruit all patients operated on by the General Surgery and Urology Departments with a diagnosis of GF at the University Hospital over 22 years. Mortality, the Fournier gangrene severity index (FGSI), and fecal diversion (either surgical (colostomy) or straight (Flexi-seal)) are collected. RESULTS: A total of 149 patients met the inclusion criteria. FG's most frequent cause was a perianal abscess (107 patients-72%). Eighteen patients (12%) died of a specific cause of FG. Age (p = 0.014) and patients with an oncological history (p = 0.038) both were the only mortality risk factors for mortality according to logistic regression. Fifty patients required some form of fecal diversion in the postoperative period (32 colostomies and 18 Flexi-seal). Neither the use of postoperative fecal diversion (surgical or Flexi-seal) nor the timing of its use had any effect on postoperative mortality. CONCLUSIONS: One in eight patients died in the immediate postoperative period secondary to FG. Despite improved outcomes, 22% required a colostomy during admission. However, neither the performance of a colostomy nor the timing was associated with decreased FG-associated mortality. Non-invasive methods should be used first and surgical bowel diversion should be postponed as long as possible.

The role of C-reactive protein albumin ratio for predicting mortality in patients with Fournier's gangrene.

BACKGROUND: Fournier's gangrene (FG) is a rapidly progressing and life-threatening necrotizing fasciitis of the genital and perineal regions. To estimate the mortality rate associated with FG, Laor et al. developed the FG severity index (FGSI), an index with proven prognostic significance. On the other hand, the C-reactive protein (CRP)/albumin (CAR) ratio is a proven objective marker of inflam-matory response. In light of the foregoing, the objective of this study is to assess the prognostic value of the CAR ratio in predicting mortality in patients with FG in comparison with FGSI. METHODS: This retrospective study consisted of 58 patients who were operated on for FG between 2019 and 2022. Research data were obtained from electronic and paper patient files, surgery notes, clinical follow-up forms, anamnesis, intensive care forms, and laboratory test results obtained from the hospital automation system. The clinical course of each patient was reviewed based on these records. The relationships between patients' CAR ratios and their demographic and clinical characteristics, including age, gender, and comorbidities, whether ostomy was performed, length of hospital stay, growth in wound culture, isolated bacterial species, FGSI scores, and laboratory test results (hemoglobin, sodium, potassium, bicarbonate, glucose, blood urea nitrogen (BUN), creatinine, albumin, and CRP levels, white blood cell counts, hematocrit values, glucose-to-potassium, neutrophil-to-lymphocyte, platelet-to-lymphocyte, and lymphocyte-to-CRP ratios) and the prognostic power of CAR ratio in predicting the mortality associated with FG were investigated. RESULTS: The mean age of the study group, 45 male and 13 female, was 57 (min. 17, max. 85) years. The most common predisposing factor was diabetes mellitus (DM), which was present in 32 (55.1%) patients. The most common symptoms at admission were erythema (89.6%), swelling/hardening (82.7%), pain (41.3%), fever (31%), and purulent discharge (37.9%). Of the 58 patients included in the study, six had died. The most common comorbidity, second to DM (55.1%), was cardiovascular disease (39.6%). The median ages of patients who had died and survived were 60 (min. 56, max. 85) and 56 (min. 18, max. 80) years, respectively. CAR ratio effectively differentiated FG patients who had survived from those who had died (area under the curve [AUC]: 0.907 [0.824-0.984]). The CAR ratio cutoff value of 2.8 effectively differentiated FG patients and FSGI scores who had survived from those who had died (AUC: 0.904 [0.823-0.992]). CONCLUSION: The study findings demonstrated that the CAR ratio might serve as an effective biomarker in predicting the mortal-ity associated with FG.

Preoperative computed tomography in Fournier's gangrene does not delay time to surgery.

PURPOSE: Fournier's gangrene (FG), a rapidly progressive necrotizing soft tissue infection of the external genitalia and perineum, necessitates urgent surgical debridement. The time to surgery effect of preoperative computed tomography (CT) in managing this condition is yet to be fully explored. The purpose of this study was to assess whether obtaining a preoperative CT in patients with FG impacts the time to surgical intervention. METHODS: This was a single-center retrospective study of patients who underwent CT prior to surgical debridement of FG during a 9-year period vs patients who did not undergo CT. In 76 patients (male = 39, mean age = 51.8), 38 patients with FG received a preoperative CT, and 38 patients with FG did not receive CT prior to surgical debridement. Time to operating room and outcome metrics were compared between CT and non-CT groups. RESULTS: The time from hospital presentation to surgical intervention was not significantly different between patients who underwent CT and those who did not (6.65 ± 3.71 vs 5.73 ± 4.33 h, p = 0.37). There were also no significant differences in cost ($130,000 ± $102,000 vs $142,000 ± $152,000, p = 0.37), mortality (8 vs 7, p = 1), duration of hospital stay (15.5 ± 15 vs 15.7 ± 11.6 days, p = 0.95), average intensive care unit stay (5.82 ± 5.38 days vs 6.97 ± 8.58 days, p = 0.48), and APACHE score (12 ± 4.65 vs 13.9 ± 5.6, p =0.12). CONCLUSION: Obtaining a preoperative CT did not delay surgical intervention in patients with FG.

Comparison of different scoring systems for predicting in-hospital mortality for patients with Fournier gangrene.

PURPOSE: To compare different scoring systems for predicting in-hospital mortality in patients with Fournier gangrene (FG). METHODS: A comprehensive literature search was performed to find all scoring systems that have been proposed previously as a predictor for in-hospital mortality in patients with FG. Data of all patients with FG who were hospitalized in one of Indonesia's largest tertiary referral hospitals between 2012 and 2022 were used. The receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance of the scoring systems. RESULTS: Ten scoring systems were found, i.e., Fournier's Gangrene Severity Index (FGSI), Uludag FGSI, simplified FGSI, NUMUNE Fournier score (NFS), Laboratory Risk Indicator for Necrotizing Fasciitis, age-adjusted Charlson comorbidity index, sequential organ failure assessment (SOFA), quick SOFA, acute physiology and chronic health evaluation II, and surgery APGAR score (SAS). Of 164 FG patients included in the analyses, 26.4% died during hospitalization. All scoring systems except SAS could predict in-hospital mortality of patients with FG. Three scoring systems had areas under the ROC curve (AUROC) higher than 0.8, i.e., FGSI (AUROC 0.905, 95% confidence interval (CI) 0.860-0.950), SOFA (AUROC 0.830, 95% CI 0.815-0.921), and NFS (AUROC 0.823, 95% CI 0.739-0.906). Both FGSI and SOFA had sensitivity and NPV of 1.0, whereas NFS had a sensitivity of 0.74 and an NPV of 0.91. CONCLUSION: This study shows that FGSI and SOFA are the most reliable scoring systems to predict in-hospital mortality in FG, as indicated by the high AUROC and perfect sensitivity and NPV.

Evaluating the Safety of Sodium-Glucose Cotransporter-2 Inhibitors in a Nationwide Veterans Health Administration Observational Cohort Study.

Sodium-glucose cotransporter-2 inhibitors (SGLT-2is) are indicated in patients with or without type 2 diabetes mellitus atherosclerotic cardiovascular disease, chronic kidney disease, or heart failure. Postmarket surveillance data have identified many safety signals which warrants further investigation. We aimed to compare the safety of SGLT-2i and glucagon-like peptide-1 receptor agonists (GLP-1RA). Using the Veterans Health Administration nationwide database, patients with type 2 diabetes mellitus who were newly initiated on a SGLT-2i or GLP-1RA between April 1, 2013 and September 1, 2020 were identified. The primary outcome was the incidence of any amputation, below-knee amputation (BKA), all clinical fractures, hip fracture, Fournier gangrene, acute pancreatitis, diabetic ketoacidosis (DKA), serious urinary tract infections (UTIs), and venous thromboembolism (VTE). All outcomes were compared between the treatment groups. Cox proportional hazard models were used to estimate adjusted hazard ratios (aHRs) for the comparative analysis. A total of 70,694 propensity-matched new users of SGLT-2i and GLP-1RA were identified. The use of SGLT-2 inhibitors, compared with GLP-1RA, was not associated with an increased rate of any amputation (aHR 1.02, 95% confidence interval [CI] 0.82 to 1.27), BKA (aHR 1.05, 95% CI 0.84 to 1.32), all clinical fractures (aHR 0.94, 95% CI 0.86 to 1.03), hip fractures (aHR 0.82, 95% CI 0.50 to 1.32), DKA (aHR 1.66, 95% CI 0.97 to 2.85), VTE (aHR 1.02, 95% CI 0.80 to 1.30), acute pancreatitis (aHR 1.02, 95% CI 0.80 to 1.30), and Fournier gangrene (aHR 0.92 95% CI 0.61 to 1.38). Lower rates of serious UTIs were observed in the SGLT-2i group than in the GLP-1RA group (aHR 0.74, 95% CI 0.64 to 0.84). This real-world study found that SGLT-2i use compared with GLP-1RA did not increase the rate of amputation, BKA, clinical fractures, hip fracture, Fournier gangrene, acute pancreatitis, DKA, serious UTIs, and VTE in veteran patients.

Can HALP score, a new prognostic tool, take the place of traditional scoring systems in Fournier's gangrene?

PURPOSE: Fournier's Gangrene (FG) is a fatal condition, therefore prognosis prediction is a crucial step before treatment planning. We aimed to investigate the predictive value of Hemoglobin, Albumin, Lymphocyte and Platelet (HALP) score which is frequently employed in vascular disorders and malignancies, on disease severity and survival in FG patients and to compare HALP score with well-known scoring systems on this aspect. MATERIALS AND METHODS: Eighty-seven men who had surgical debridement for FG between December 2006 and January 2022 were included in this study. Their symptoms, physical examination findings, laboratory tests, medical histories, vital signs, extent and timing of the surgical debridement and antimicrobial therapies were noted. The HALP score, Age-adjusted Charlson Comorbidity Index (ACCI) and Fournier's Gangrene Severity Index (FGSI) were evaluated for their predictive values for survival. RESULTS: FG patients were grouped as survivors (Group 1, n = 71) and non-survivors (Group 2, n = 16) and the results were compared. The mean ages of survivors (59 ± 12.55 years) and non-survivors (64.5 ± 14.6 years) were similar (p = 0.114). The median size of necrotized body surface area was 3% in Group 1 and 4.8% in Group 2 (p = 0.013). On admission, hemoglobin, albumin and serum urea levels and white blood cell counts were significantly different in two study groups. Two study groups were similar for HALP scores. However, ACCI and FGSI scores were greater significantly in non-survivors. CONCLUSIONS: Our results indicated that HALP score does not predict a survival successfully in FG. However, FGSI and ACCI are successful outcome predictors in FG.

Vacuum sealing drainage to treat Fournier's gangrene.

BACKGROUND: Vacuum sealing drainage (VSD) is widely applied in complex wound repair. We aimed to compare traditional debridement and drainage and VSD in treating Fournier's gangrene (FG). METHODS: Data of patients surgically treated for FG were retrospectively analyzed. RESULTS: Of the 36 patients (men: 31, women: 5; mean age: 53.5 ± 11.3 [range: 28-74] years) included in the study, no patients died. Between-group differences regarding sex, age, BMI, time from first debridement to wound healing, number of debridements, FGSI, and shock were not statistically significant (P > 0.05). However, lesion diameter, colostomy, VAS score, dressing changes, analgesic use, length of hospital stay, and wound reconstruction method (χ2 = 5.43, P = 0.04) exhibited statistically significant differences. Tension-relieving sutures (6 vs. 21) and flap transfer (4 vs. 2) were applied in Groups I and II, respectively. CONCLUSION: VSD can reduce postoperative dressing changes and analgesic use, and shrunk the wound area, thereby reducing flap transfer in wound reconstruction.
