Necrotizing fasciitis following measles vaccine administration: a case report

Early diagnosis of necrotizing fasciitis: Imaging techniques and their combined application

Necrotizing fasciitis is a clinical, surgical emergency characterized by an insidious onset, rapid progression, and a high mortality rate. The disease's mortality rate has remained high for many years, mainly because of its atypical clinical presentation, which prevents many cases from being diagnosed early and accurately, resulting in patients who may die from uncontrollable septic shock and multi-organ failure. But unfortunately, no diagnostic indicator can provide a certain early diagnosis of NF, and clinical judgement of NF is still based on the results of various ancillary tests combined with the patient's medical history, clinical manifestations, and the physician's experience. This review provides a brief overview of the epidemiological features of NF and then discusses the most important laboratory indicators and scoring systems currently employed to diagnose NF. Finally, the latest progress of several imaging techniques in the early diagnosis of NF and their combined application with other diagnostic indices are highlighted. We point out promising research directions based on an objective evaluation of the advantages and shortcomings of different methods, which provide a basis for further improving the early diagnosis of NF.

A case of necrotizing fasciitis following intra-articular injections - Iatrogenic or spontaneous?

Here, we report a case of necrotizing fasciitis following intra-articular injection of hyaluronic acid. A 73-year-old female received intra-articular injections of hyaluronic acid due to arthralgia at the left shoulder and knee, and was found dead in her living room at one day. At the forensic autopsy, injection marks with bullae and erythema were found at the left shoulder and knee and liquefactive necrosis of muscle tissues was observed in the left but not right extremities. Histopathological examinations of the left upper arm and thigh revealed severe rhabdomyolysis with lots of bacterial clusters. Bacteriological examinations detected group A Streptococcus from intracardiac blood and affected muscle tissues. Postmortem biochemical analysis of blood showed escalated blood urea nitrogen (133.8 mg/dL), creatinine (4.57 mg/dL) and C-reactive protein (45.0 mg/dL). The cause of her death was diagnosed as streptococcal toxic shock syndrome (STSS). Moreover, it was suggested that the injection was inappropriately conducted and served as a portal of bacterial entry.

Necrotizing Soft Tissue Infection: A Single-Center Retrospective Study of Treatment and Outcomes

Introduction

Necrotizing fasciitis is a severe inflammatory disease of the body's soft tissue characterized by spreading rapidly and high mortality. Rapid surgical intervention along with other supportive measures of treatment have a great impact on the outcome of treatment.

Material and methods

This study was conducted by a retrospective medical record review of all patients with a microbiologically and clinically confirmed diagnosis of necrotizing fasciitis who were admitted to the general surgery department at the General Hospital Novi Pazar, Serbia, during the period between 2017 and 2020. Demographic, clinical, laboratory, and microbiology data were analyzed.

Results

A total of 13 cases were identified, which represents 0.21% of the total number of patients treated at the surgical department during the period January 2017 to November 2020. The mean age of patients was 55 years, with a male/female ratio of 1:1.6. All of them had at least one comorbidity and more than half had three or more. Diabetes, cardiovascular diseases, and obesity were the most common comorbidities. The most common causes of infection were Klebsiella spp, Pseudomonas aeruginosa, S. pyogenes, and S. aureus. All patients received multiple surgical interventions (mean 2.3).

Conclusion

Treating necrotizing fasciitis requires a multidisciplinary approach. Early diagnosis and rapid clinical response allow for better disease outcomes. Getting to know more about necrotizing fasciitis will help doctors make better decisions when treating it.
