Fournier's gangrene complicated by lower limb necrotising fasciitis and pelvic bone osteomyelitis: A case report with literature review.

INTRODUCTION AND IMPORTANCE: Fournier's gangrene is a urological emergency associated with high mortality and morbidity. Severe gangrene resulting in pelvic bone and lower limb involvement are extremely rare. CASE PRESENTATION: We report a rare case of Fournier's gangrene that is complicated by necrotising fasciitis of the lower limb and osteomyelitis of the pelvic bone, in a patient with previous prostatic adenocarcinoma. The patient was promptly resuscitated, started on broad spectrum antibiotics and then underwent an emergent surgical debridement, followed by multiple relook debridement and definitive reconstruction. Throughout the patient's hospitalisation, he was managed in a multidisciplinary team involving surgeons from different specialities, physicians and allied health staff. CLINICAL DISCUSSION: Extension of Fournier's gangrene into distant structures is rare but serious complications. To date, there is only one other case reported in literature. The relationship between prior prostatic malignancy and Fournier's gangrene can be explored in subsequent studies. CONCLUSION: We present a rare case of Fournier's gangrene with pelvic and distal limb involvement. We highlight the possible yet devastating complications of this disease and discuss treatment options available for the holistic management of patients with Fournier's gangrene.

The microbiological profile of necrotising fasciitis at a secondary level hospital in Gauteng.

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.

Limb presentations of invasive Group A Streptococci infection in children.

Infections with invasive Group A streptococcus can have a wide range of presentations and be life threatening if not diagnosed and managed rapidly. Limb presentations in children can be especially challenging and we present our experience to help manage such cases. There can be multiple foci of infection with seeding to avascular structures. Therefore, we advocate maintaining a high degree of clinical suspicion when assessing this group of patients, who are often critically unwell, and have varying presentation. Early and aggressive surgical intervention may be key for disease control.

Necrotising fasciitis with extensive necrosis caused by Lactobacillus: a case report.

BACKGROUND: Necrotising fasciitis (NF) is a life-threatening soft-tissue infection that rapidly destroys the epidermis, subcutaneous tissue, and fascia. Despite their low virulence, Lactobacillus spp. can cause NF, and because of its rare incidence, there is limited information about its molecular and clinicopathological characteristics. We report a rare case of NF in a patient with type 2 diabetes mellitus diagnosed on admission and severe obesity due to infection with two types of Lactobacillus spp. that manifested in extensive necrosis. CASE PRESENTATION: A 48-year-old woman was referred to our hospital with a complaint of difficulty walking due to severe bilateral thigh pain. She presented with mild erythema, swelling, and severe skin pain extending from the pubic region to the groin. The patient was morbidly obese, had renal dysfunction, and had diabetes mellitus diagnosed on admission.; her LRINEC (Laboratory Risk Indicator for Necrotising Fasciitis) score was 9, indicating a high risk of NF. An exploratory surgical incision was made, and NF was diagnosed based on fascial necrosis. Emergent surgical debridement was performed, and cultures of the tissue culture and aspirated fluid/pus revealed two types of Lactobacillus spp.: Lactobacillus salivarius and L. iners. The patient was admitted to the intensive care unit (ICU), where antibiotics were administered and respiratory and circulatory management was performed. Diabetic ketoacidosis was detected, which was treated by controlling the blood glucose level stringently via intravenous insulin infusion. The patient underwent a second debridement on day 11 and a skin suture and skin grafting on day 36. The patient progressed well, was transferred from the ICU to the general ward on day 41, and was discharged unassisted on day 73. CONCLUSIONS: Lactobacillus spp. are rarely pathogenic to healthy individuals and can scarcely trigger NF. However, these bacteria can cause rare infections such as NF in immunocompromised individuals, such as those with diabetes and obesity, and an early diagnosis of NF is imperative; surgical intervention may be required for the prevention of extensive necrosis. The LRINEC score may be useful for the early diagnosis of NF, even for less pathogenic bacteria such as Lactobacillus.

Cervical Necrotising Fasciitis Leading to Critical Airway Compromise: A Case Report of Successful Airway Management With Awake Fibreoptic Intubation.

A 56-year-old female patient with a history of breast cancer, anxiety, and depression developed rapid-onset cervical necrotising fasciitis following a fall at home where she sustained multiple rib fractures and lacerations. The case highlights the challenge of managing a rapidly progressing airway obstruction and the successful management of the patient's condition with awake fibreoptic intubation and subsequent surgical intervention.

Necrotizing Fasciitis Associated With Toxic Shock Syndrome.

Necrotizing fasciitis is a rapidly progressing bacterial infection that affects the deep fascia and subcutaneous tissues, often resulting in tissue necrosis and systemic toxicity. This case involves a male in his late forties who initially sought emergency care for a minor rash on his right lower extremity and symptoms of a viral illness. Despite an initial diagnosis of hematoma, his symptoms rapidly escalated within 24 hours, prompting his return to the emergency room. During this subsequent visit, signs of septic shock emerged, accompanied by a worsening rash and blister formation. Admitted to the intensive care unit, our patient received urgent treatment, including broad-spectrum antibiotics and surgical debridement based on the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score for assessing necrotizing fasciitis severity. Further debridement and a fasciotomy were performed, leading to improved clinical conditions, stabilized vitals, and normalized laboratory results. This case underscores the critical importance of early clinical suspicion, prompt diagnosis, and a collaborative, team-based approach in successfully managing necrotizing fasciitis.

Fournier's gangrene: a review of predictive scoring systems and practical guide for patient management.

This article aims to provide a practical guide for patient management and an overview of the predictive scorings for Fournier's gangrene (FG) that are available to aid clinicians. A literature was performed reviewing currently used scoring systems for FG and presenting a practical guide for its management based on the available evidence. There are four specific scoring systems available for the assessment of FG although few other non-specific and generic tools also exist. These specific tools include Laboratory Risk Indicator for Necrotizing Fasciitis, Fournier's Gangrene Severity Index, Uludag Fournier's Gangrene Severity Index, and Simplified Fournier's Gangrene Severity Index and help calculate expected mortality. Our proposed algorithm covers primary assessment, resuscitative interventions, initial investigations, urgent care, post-operative care, and long-term follow-up. The management of the FG patient can be divided into initial resuscitation, surgical debridement, ongoing ward management with antibiotic therapy, wound reconstruction, and long-term follow-up. Each facet of care is vital and requires multidisciplinary team expertise for optimal outcomes. Whilst mortality continues to improve, it remains significant, reflecting the severe and life-threatening nature of FG. More research is certainly needed into how this care is individualised, and to ensure that long-term outcomes in FG include quality of life measures after discharge.

A parotid abscess out of control resulting in craniocervical necrotising fasciitis in the context of diabetes mellitus-a case report and review of the literature.

Background: Necrotising fasciitis is an aggressive life-threatening infective process rarely making an appearance in the head and neck region and its development secondary to parotid abscess is exceptionally rare and scarcely reported in the literature. This case report serves to guide otolaryngologists with respect to its recognition and offers an alternative approach to craniocervical necrotising fasciitis with multiple neck explorations, use of antimicrobial impregnated packing enabling delayed reconstruction with lower morbidity. Case Description: A 76-year-old female with a body mass index of 36.2 kg/m2 and a 30-year history of poorly controlled type 2 diabetes mellitus (HbA1c 91 mmol/moL), presented to the outpatient otolaryngology clinic with right sided parotid mass with minimal erythema, hyperglycaemia (19.2 mmol/L) and no cranial neuropathies. However, the aggressive nature of the parotid abscess triggered by group A streptococcus and Staphylococcus epidermidis led to sepsis and extensive non-odontogenic necrotising fasciitis involving the lateral neck mandating multiple surgical debridement and neck explorations, prolonged intravenous antibiotics with interval definitive reconstruction. A cervicofacial rotational sternocleidomastoid flap was utilised to conceal the defect with patient experiencing a remarkable recovery. The patient's immunosuppressive state from poorly controlled diabetes mellitus and multi-lineage cytopenia is likely to have contributed to a prolonged recovery. Conclusions: This case report highlights the significance of repeat explorations and the need to give time for tissue healing as it unlocks options for reconstruction and reduce overall patient morbidity. Bismuth iodoform paraffin paste packing is a valuable tool with this case demonstrating its use an antiseptic and haemostatic agent in necrotising fasciitis and its ability to create an atmosphere to enable tissue healing minimising need for large-scale reconstructions. The absence of crepitus should not discourage the treating clinician from suspecting necrotising fasciitis of the neck. To limit successive cases, early prevention through aggressive control of predisposing systemic conditions including diabetes mellitus is needed. Moreover, when aggressive infections arise, the clinician should investigate for contributing systemic conditions.

Laparoscopic treatment of a patient with multiple organ dysfunction syndrome induced by necrotising fasciitis.

Necrotising fasciitis (NF) is an uncommon surgical emergency that threatens the life and health of patients. We report the treatment of a 76-year-old female patient with NF. The patient developed NF due to chronic poor glycaemic control, which further progressed to multiple organ dysfunction syndrome due to the severity of the hyperglycaemia. After resuscitation at the intensive care unit, surgical treatment was recommended and the patient underwent laparoscopic surgery. She had an uneventful post-operative recovery with aggressive anti-inflammatory therapy, glycaemic control and systemic nutritional support. There were no recurrences during the next 6 months of follow-up. NF should be diagnosed and treated as early as possible to gain valuable treatment time for the patient. Laparoscopic surgery is a treatment option.

Necrotising fasciitis presenting as a blister: A case report on improving early recognition of surgical site infection following caesarean delivery.

Early recognition and treatment of surgical site infection (SSI) may prevent devastating consequences of wound infections complicating caesarean delivery (CD). SSI complicates 3-15% of CDs; among the severe forms are necrotising fasciitis (NF) and clostridial gas gangrene, with the latter being the most rapidly spreading and fatal. The aim of this report is to improve early recognition of SSI complicating CD. An obese 32-year-old woman, gravida 2 para 1, with a previous uncomplicated vaginal delivery had a CD for fetal compromise in a district hospital. On day 6 after delivery, she presented to the same district hospital with a small blister located on her abdomen above the CD wound. The area around the blister was firm but had no crepitus. The blister was managed expectantly but spread rapidly and had a dusky colour. Both the blister and the surgical site for CD subsequently became foul smelling and the patient was managed in a regional hospital, where she had antibiotic therapy, wound debridement, negative-pressure wound therapy, and secondary wound closure. Healing was complete 69 days after the debridement. The histological report of the wound biopsy confirmed NF. In conclusion, blistering around a surgical site is suggestive of NF. Healthcare professionals managing surgical wounds should have ongoing training on SSI to prevent lack of problem recognition in wound care. All healthcare facilities managing surgical wounds should establish a functional wound care clinic to improve early recognition and treatment of SSI. This entails effective integration of postnatal and CD wound services to improve the care of SSI. Therefore, the algorithm included in this article will be invaluable to care providers.

Validating the laboratory risk indicator for necrotizing fasciitis (LRINEC) score: a prospective cohort study in a resource limited setting.

BACKGROUND: Necrotising fasciitis is a rare and fulminant soft tissue infection. Prompt surgical debridement of the involved soft tissues and necrotic fascia is its definitive treatment, with any delay associated with increased mortality. The LRINEC score is a scoring system initially designed to aid in early diagnosis of necrotising fasciitis to facilitate early surgical intervention. This score utilizes common biochemical tests to produce a score of 0-13, stratifying patients into risk categories. METHODS: A prospective cohort study was designed including all patients presenting with severe soft tissue infection from June 2011 to January 2014. Exclusion criteria included: less than 15 years or above 90 years, antibiotics within 48 h of presentation or prior debridement of their soft tissue infection. All patients underwent routine blood investigations, required for calculation of the LRINEC score. RESULTS: The positive predictive value of the LRINEC score was 95.42%, whilst the negative predictive value was 81.16%. There was a statistically significant correlation between white cell count, serum creatinine, blood glucose level and positive histopathology. The mortality rate for patients with histopathologically-confirmed necrotising fasciitis was 10%. CONCLUSION: The LRINEC score is a clinical adjunct to risk stratify patients presenting to the emergency department with soft tissue infections. It utilizes common blood tests commonly to calculate a score, which risk stratifies patients. The use of this scoring system can facilitate better allocation of resources and aids in the decision to transfer patients in rural or regional settings, which are often complicated by being a resource limited environment.

Streptococcal toxic shock syndrome with associated necrotising fasciitis necessitating amputation of the lower extremity - A case report.

Streptococcal toxic shock syndrome is a severe, invasive and life-threatening infection associated with a high risk of rapid multiorgan failure. It is associated with high morbidity and mortality. Streptococcal toxic shock syndrome is very commonly caused by group A-Streptococcus pyogenes, ß-haemolytic streptococcus, a typical human-specific gram-positive bacterial pathogen. We present here the case report of a 54-year-old man with a rapidly progressive streptococcal toxic shock syndrome due to necrotising fasciitis of the left lower limb and describe the successful treatment through close interdisciplinary care.

Management of Fournier's gangrene: a practical guide for clinicians.

Fournier's gangrene is a localised form of necrotising fasciitis affecting the external genitalia, perineal and perianal regions. Although rare, it is associated with high rates of morbidity and mortality, so clinician awareness is essential for prompt treatment. Risk factors include diabetes mellitus, hypertension, chronic alcoholism and immunosuppression. Perineal pain in patients with sepsis should be treated with a high level of suspicion and early surgical referral is required as prompt debridement can improve outcomes. Repeated surgical intervention and antimicrobial therapy are often needed and recovery can take a long time, with a long-term impact on quality of life. This article discusses the natural history of Fournier's gangrene, aetiology, risk factors, investigations and treatments with an algorithm to support clinical practice.

Necrotising fasciitis secondary to a perforated hepatic flexure tumour - A case report.

INTRODUCTION AND IMPORTANCE: Necrotising fasciitis caused by a perforated colon cancer is a very rare occurrence and can be very life threatening needing urgent intervention involving tissue salvage and oncological treatment. There is not enough evidence in the literature regarding management of the same. This case report highlights one such case along with management principles. PRESENTING CASE: We present a 66 year old male with 3 weeks of a progressive right lower quadrant lump and constitutional symptoms. He had a computed tomography scan demonstrating a complex collection in the right anterior abdominal wall, containing multiple locules of gas and air fluid levels near an abnormally thickened hepatic flexure. He was taken for an urgent debridement followed by laparotomy which demonstrated extensive abdominal wall necrotising fasciitis secondary to a perforated hepatic flexure tumour invading into the duodenum. He was given a diverting ileostomy. He had a relook laparotomy the next day for a right hemicolectomy and part of the duodenum resected with a refashioned end ileostomy. He was subsequently managed on the ward for two weeks and then discharged home. He remains well and has been referred to medical oncology for adjuvant chemotherapy. CLINICAL DISCUSSION: A two step surgical approach was key in this case, first step for source control and the second step focused on an oncological resection. CONCLUSION: This case explains the importance of excluding malignant causes of necrotising fasciitis. Perforated cancers can manifest as necrotising fasciitis and management should include timely debridement as well as oncological principles.

Traumatic mucormycosis caused by Apophysomyces species - A case series.

Background: Apophysomyces species are emerging as the second most common agent of mucormycosis in India. It is worrisome as it affects predominantly immunocompetent host unlike other Mucorales. Unfortunately, the most common presentation is necrotising fasciitis which can be overlooked as bacterial infection. Results: Seven cases of mucormycosis due to Apophysomyces species were detected in our hospital between January 2019 and September 2022. Mean age was 55 years and all were males. Six patients presented with necrotising soft tissue infection following accidental or iatrogenic trauma. In four cases, multiple fractures over the body were observed. Median days between admission to laboratory diagnosis was 9 days. All isolates were phenotypically identified as Apophysomyces variabilis. Multiple wound debridements, on an average two, was performed in all the cases and amputation performed in two patients. Three patients recovered, two could not be treated due to financial constraints and lost to followup and two patients died. Conclusion: Through this series, we anticipate to upheave awareness among the orthopedician community about this emerging infection and contemplate it in appropriate case settings. All patients with necrotising soft tissue infection following trauma and significant degree of wound contamination with soil should be suspected for traumatic mucormycosis at the time of wound assessment.

The performance of clinical risk scores in the diagnosis of necrotising fasciitis.

OBJECTIVE: Necrotising fasciitis (NF) is a quickly progressing and potentially life-threatening infection, involving the fascia and subcutaneous tissues. The diagnosis of this disease is challenging, especially due to a lack of specific clinical signs. In order to ensure a better and quicker identification of NF patients, a laboratory risk indicator score has been developed for NF (LRINEC). A variant has widened this score by adding clinical parameters (modified LRINEC). This study shows current outcomes of NF and compares the two scoring systems. METHODS: This study was conducted between 2011 and 2018, and included patient demographics, clinical presentations, sites of infection, comorbidities, microbiological and laboratory findings, antibiotic therapies and LRINEC as well as modified LRINEC scores. The primary outcome was in-hospital mortality. RESULTS: A cohort of 36 patients, diagnosed with NF, were included in this study. The mean hospital stay was 56 days (±38.2 days). The mortality rate in the cohort was 25%. The sensitivity of the LRINEC score was 86%. Calculation of the modified LRINEC score showed an improvement of the sensitivity to 97%. The average LRINEC score and modified LRINEC score for patients who died and who survived were equal (7.4 versus 7.9 and 10.4 versus 10.0, respectively). CONCLUSION: The mortality rate of NF remains high. The modified LRINEC score increased the sensitivity in our cohort to 97%, and this scoring system could be supportive in the diagnosis of NF for early surgical debridement.

Posterior cervical necrotising fasciitis: a multidisciplinary endeavour in surgery.

A 62-year-old male was diagnosed to the Emergency Department with 5-cm posterior neck carbuncle, and was subsequently discovered to have severe necrotising fasciitis intraoperatively during saucerization of the carbuncle. Subsequently, the patient was admitted to the intensive care unit and underwent combined debridement by the General Surgery, Neurosurgery and Plastic Surgery team. The large defect necessitated a trapezius flap reconstruction for coverage. Three months post-surgery, the patient had recovered well with the full range of movement of his neck.

Diagnostic and prognostic value of the Laboratory Risk Indicator for Necrotising Fasciitis (LRINEC) based on an 18 years' experience.

BACKGROUND: Necrotising fasciitis (NF) represents a rare but often life-threatening condition. Early diagnosis and surgical treatment are of vital importance. The LRINEC score was developed to distinguish necrotising fasciitis from other soft tissue infections (STI) at initial evaluation using six laboratory values. In this retrospective study, we attempted to determine the diagnostic and prognostic value of the LRINEC score. METHODS: A total of 125 patients, hospitalised in our clinic between 2003 and 2021 with a histologically confirmed diagnosis of necrotising fasciitis (NF group) and 319 patients with surgically treated soft tissue infections (STI group) were included in this study. Individual LRINEC scores were calculated and analysed retrospectively. RESULTS: The sensitivity of the LRINEC score at the cut-off point of ≥ 6 was 59%, whereas the specificity was 82%. The positive and negative predictive values were 57% and 84%, respectively. The mean LRINEC score was significantly higher in the NF group than in the STI group (6.0 compared to 2.4, respectively). All clinical outcome parameters such as amputation and mortality rates (15% vs 1%) were found to be significantly higher in the NF group (p<0.001). Within the NF group, there was no statistically significant association between the LRINEC score and clinical outcomes except for the necessary number of operations. CONCLUSION: In isolation, we found the LRINEC score not to be a reliable enough diagnostic tool for the differentiation between NF and other soft tissue infections, because of its low sensitivity. Although we cannot recommend it as a prognostic tool either, we do believe it can be a useful adjunct to the clinical suspicion of NF.
