Interventions for necrotizingsofttissueinfections in adults. Necrotizingsofttissueinfections (NSTIs) are severe and rapidly spreading softtissueinfections of the subcutaneous tissue, fascia, or muscle, which are mostly caused by bacteria. Associated rates of mortality and morbidity are high, with the former estimated at around 23%, and disability, sequelae, and limb loss occurring in 15% of patients. Standard management includes intravenous empiric antimicrobial therapy, early surgical (...) debridement of necrotictissues, intensive care support, and adjuvant therapies such as intravenous immunoglobulin (IVIG).To assess the effects of medical and surgical treatments for necrotizingsofttissueinfections (NSTIs) in adults in hospital settings.We searched the following databases up to April 2018: the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trials registers, pharmaceutical company trial results databases, and the US Food and Drug
What Is the Accuracy of Physical Examination, Imaging, and the LRINEC Score for the Diagnosis of NecrotizingSoftTissueInfection? (SRS diagnosis) What Is the Accuracy of Physical Examination, Imaging, and the LRINEC Score for the Diagnosis of NecrotizingSoftTissueInfection? TAKE-HOME MESSAGE Computed tomography (CT) has superior sensitivity compared with radiography for the diagnosis of necrotizingsofttissueinfection, although different imaging ?ndings have various diagnostic test (...) characteristics. No single element of the physical examination, radiography, or the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score has suf?cient sensitivity to exclude necrotizingsofttissueinfection.

NecrotizingSoftTissueInfections S.aureus - but not S.pyogenes- isolates display high rate of internalization and cytotoxicity toward human myoblasts. NecrotizingSoftTissueInfections (NSTIs) caused by group A Streptococcus (GAS) and occasionally by Staphylococcus aureus (SA) frequently involve the deep fascia and often lead to muscle necrosis.To assess the pathogenicity of GAS and SA for muscles in comparison to keratinocytes, adhesion and invasion of NSTI-GAS and NSTI-SA isolates were (...) assessed on these cells, Bloodstream infections (BSI-SA) and non-invasive coagulase negative Staphylococci (CNS) isolates were used as controls.NSTI-SA and BSI-SA exhibited stronger internalization into human keratinocytes and myoblasts than NSTI-GAS or CNS. SA internalization reached over 30% in human myoblasts due to a higher percentage of infected myoblasts (>11%) as compared to keratinocytes (<3%). Higher cytotoxicity for myoblasts of NSTI-SA as compared to BSI-SA, was attributed to higher levels
Clinical parameters and outcomes of necrotizingsofttissueinfections secondary to gastrointestinal fistulas. Necrotizingsofttissueinfections (NSTIs) is severe surgical infections which can occur following trauma or abdominal surgery. NSTIs secondary to gastrointestinal (GI) fistula is a rare but severe complication.A retrospective cohort study was performed on all subjects presenting with GI fistulas associated NSTIs were included. Clinical characteristics, microbiological profile
Periocular necrotizingsofttissueinfection in Greater Copenhagen. Necrotizingsofttissueinfection, also known as necrotizing fasciitis (NF), is a fast-spreading life-threatening infection that most commonly affects the lower limbs, groin, or abdomen. Periocular necrotizing fasciitis (PNF) is rare. Limited data exist on PNF immune cell subset; hence, this study aims to determine the representation of immune cell subsets in patients diagnosed with PNF using immunohistochemical stainings.All (...) patients diagnosed with PNF at Copenhagen University Hospital from 2008 to 2018 were included. Their electronic medical records and pathology reports were assessed, and available tissue specimens were reviewed and stained with monoclonal antibodies for CD1a+ Langerhans' cells, CD3+ T lymphocytes, CD15+ granulocytes, CD44+ lymphohematopoietic cells, CD68+ histiocytes, CD79α+ B lymphocytes, and FXIIIa+ dendritic macrophages and Langerhans' cells. The number of positive cells was counted, and an average
Necrotizing skin and soft-tissueinfections in the intensive care unit. Necrotizing skin and soft-tissueinfections (NSTI) are rare but potentially life-threatening and disabling infections that often require intensive care unit admission.To review all aspects of care for a critically ill individual with NSTI.Literature search using Medline and Cochrane library, multidisciplinary panel of experts.The initial presentation of a patient with NSTI can be misleading, as features of severe systemic (...) toxicity can obscure sometimes less impressive skin findings. The infection can spread rapidly, and delayed surgery worsens prognosis, hence there is a limited role for additional imaging in the critically ill patient. Also, the utility of clinical scores is contested. Prompt surgery with aggressive debridement of necrotictissue is required for source control and allows for microbiological sampling. Also, prompt administration of broad-spectrum antimicrobial therapy is warranted, with the addition
Diabetes and necrotizingsofttissueinfections-A prospective observational cohort study: Statistical analysis plan. Necrotizingsofttissueinfections (NSTIs) are rare but carry a high morbidity and mortality. The multicenter INFECT project aims to improve the understanding of the pathogenesis, clinical characteristics, diagnosis, and prognosis of NSTIs. This article describes the study outline and statistical analyses that will be used.Within the framework of INFECT project, patients
Pivotal Role of Preexisting Pathogen-Specific Antibodies in the Development of NecrotizingSoft-TissueInfections. Necrotizingsoft-tissueinfections (NSTI) are the most severe form of bacterial-induced tissue pathology. Their unpredictable onset and rapid development into life-threatening conditions considerably complicate patient treatment. Understanding the risk factors for NSTI in individual patients is necessary for selecting the appropriate therapeutic option.We investigated the role (...) to disease progression. Thus, all patients with NSTIs included in this study exhibited a deficiency in specific antibodies directed against the causative S. pyogenes strains and the majority of their exotoxins during the initial stage of the infection. We also showed that the clinical use of IVIG during the course of infection compensates the observed antibody deficiency but is unable to halt the disease progression, once tissue necrosis has developed.These observations emphasize the requirement
NecrotizingSoftTissueInfections at a Tertiary Referral Hospital in Rwanda: Epidemiology and Risk Factors for Mortality. Necrotizingsofttissueinfections (NSTI) are emergency surgical conditions with severe physiologic and metabolic derangement. These infections are associated with increased rates of mortality and morbidity worldwide, particularly in developing countries if not diagnosed and treated early.This prospective, observational cohort study includes all patients aged 12 and above (...) of hospital stay was 23 days (IQR 8-41). The overall mortality was 26%. Multivariate regression analysis revealed four independent predictors of mortality: presence of shock at admission [odds ratio (OR) 14.15, 95% confidence interval (CI) 0.96-208.01, p = 0.050], renal failure (OR 8.92, 95% CI 1.55-51.29, p = 0.014), infection located on the trunk (OR 5.60, 95% CI 0.99-31.62, p = 0.050), and presence of skin gangrene (OR 4.04, 95% CI 1.18-13.76, p = 0.026).In Rwanda, NSTI mortality is high and associated
Optimal timing of initial debridement for necrotizingsofttissueinfection: A practice management guideline from the Eastern Association for the Surgery of Trauma. Necrotizingsofttissueinfections (NSTI) are rare, life-threatening, soft-tissueinfections characterized by rapidly spreading inflammation and necrosis of the skin, subcutaneous fat, and fascia. While it is widely accepted that delay in surgical debridement contributes to increased mortality, there are currently no practice
Stenotrophomonas maltophilia NecrotizingSoftTissueInfection in an Immunocompromised Patient To report on the first recorded case of necrotizingsofttissueinfection (NSTI) in an immunocompromised individual caused by Stenotrophomonas maltophilia in the Western Hemisphere and highlight the challenges that medical providers face in promptly diagnosing and treating NSTI in this highly vulnerable patient population.We report a case of NSTI caused by S. maltophilia in a neutropenic patient
Can necrotizingsofttissueinfection be reliably diagnosed in the emergency department? Necrotizingsofttissueinfections (NSTIs) are associated with a high mortality and require prompt recognition and treatment, consisting of aggressive surgical debridement and critical care support. Diagnosis is a key step, which is generally made in the operating room (OR), but the decision to debride requires guidance. This is frequently made on clinical grounds, but NSTI can be occult in presentation (...) and several other infective processes can mimic NSTI. It is unknown whether the various scoring systems described in the literature can enable clinicians to reliably diagnose NSTI in the emergency department, rather than the OR. The topic was debated at the 36thAnnual Point/Counterpoint Acute Care Surgery Conference and the following article summarizes the discussants points of view along with a summary of the evidence.Level III.
A Fatal Case of Super-super Obesity (BMI >80) in a Patient with a NecroticSoftTissueInfection A 35-year-old man (height, 169 cm; body weight, 240 kg; BMI, 84) visited the Department of Dermatology due to left leg pain and swelling. Focused enhanced computed tomography (CT) of the left leg ruled out complications of deep venous thrombosis. Surgical exploration of the left leg resulted in a diagnosis of necroticsofttissueinfection, but amputation was ruled out due to his weight. The patient
Associations of Plasma Nitrite, l-Arginine and Asymmetric Dimethylarginine With Morbidity and Mortality in Patients With NecrotizingSoftTissueInfections The nitric oxide system could play an important role in the pathophysiology related to necrotizingsofttissueinfection (NSTI). Accordingly, we investigated the association between plasma nitrite level at admission and the presence of septic shock in patients with NSTI. We also evaluated the association between nitrite, asymmetric
Unusual complication of bladder prolapse with subsequent diagnosis of urothelial carcinoma leading to a necrotizingsofttissueinfection after radical cystectomy There is lack of information in the literature on long-term complications of suprapubic catheters. The most common complications include urinary tract infection, bladder calculi, urine leakage and neoplastic changes. We report a case of an unusual complication of bladder prolapse, with subsequent diagnosis of urothelial carcinoma (...) , leading to a necrotizingsofttissueinfection after a radical cystectomy in a patient with long-term catheterization and its management. Due to the rarity of this complication, its management has not been well studied. In this particular case, the logical indication was radical cystectomy due to the presence of bladder necrosis.
