A Case Report of Culture-Negative Necrotizing Fasciitis With Low Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) Score: A Diagnostic Dilemma

The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score is a diagnostic tool used to help clinicians identify necrotizing fasciitis (NF) in its early stages. This tool uses six laboratory values including the patient's white blood cell count, C-reactive protein level, serum sodium level, creatinine level, and hemoglobin level to help with risk stratification. Each of these laboratory values is assigned a point value and the total score is used to determine the likelihood that a patient has NF, with a score of 6 or higher considered to be strongly indicative. The LRINEC score has gained popularity in recent years, having been included in guidelines and society recommendations for the management of NF. However, some studies have challenged the validity of the LRINEC score. Prompt and accurate diagnosis of NF is imperative given the associated mortality rate, which can be as high as 30%-40%, especially if the diagnosis is delayed. We present a case of a patient with a delayed diagnosis of NF that was initially missed in the early stages in the setting of a low LRINEC, however, growing clinical suspicion eventually led to an accurate diagnosis and management.

Timing of mortality in pediatric trauma patients: A National Trauma Data Bank analysis

BACKGROUND/PURPOSE

The classic "trimodal" distribution of death has been described in adult patients, but the timing of mortality in injured children is not well understood. The purpose of this study was to define the temporal distribution of mortality in pediatric trauma patients.

METHODS

A retrospective cohort of patients with mortality from the National Trauma Data Bank (2007-2014) was analyzed. Categorical comparison of 'dead on arrival', 'death in the emergency department', and early (≤24h) or late (>24h) inpatient death was performed. Secondary analyses included mortality by pediatric age, predictors of early mortality, and late complication rates.

RESULTS

Children (N=5463 deaths) had earlier temporal distribution of death compared to adults (n=104,225 deaths), with 51% of children dead on arrival or in ED compared to 44% of adults (p<0.001). For patients surviving ED resuscitation, children and adolescents had a shorter median time to death than adults (1.2 d and 0.8 days versus 1.6 days, p<0.001). Older age, penetrating mechanism, bradycardia, hypotension, tube thoracostomy, and thoracotomy were associated with early mortality in children.

CONCLUSIONS

Injured children have higher incidence of early mortality compared to adults. This suggests that injury prevention efforts and strategies for improving early resuscitation have potential to improve mortality after pediatric injury.
