Vaso-occlusive Pain Crisis Mimicking Mandibular Abscess in an Adolescent with Sickle Cell Disease.

In people with sickle cell disease (SCD), oral abscesses are concerning clinical conditions and carry a high risk of postoperative sickle cell complications. We present an unusual case of a 14-year-old girl with SCD whose initial presentation of facial swelling, headaches, jaw pain, and paresthesia mimicked an odontogenic abscess. She was diagnosed with vaso-occlusive crisis in the mandibular bone and successfully managed noninvasively. This is among the youngest cases of paresthesia in the lower lip in SCD, which provided a clue that postponing invasive aspiration or biopsy was possible under empiric antibiotics and close observation.

Alternative shock index cutoffs for pediatric patients outperform the Shock Index Pediatric Age-adjusted (SIPA) on strength of association with adverse outcomes in pediatric trauma patients.

BACKGROUND: The shock index is a tool for evaluating critically ill patients that is defined as the ratio of their heart rate divided by systolic blood pressure. The SI is associated with outcomes in adult trauma patients. The Shock Index Pediatric Age-adjusted was developed as a pediatric-specific tool to account for the physiologic differences of children of varying ages. There is growing interest in Shock Index Pediatric Age-adjusted, which is associated with adverse outcomes in pediatric trauma. We hypothesized that alternative shock index cutoffs based on the Advanced Trauma Life Support or the Pediatric Advanced Life Support vital sign reference ranges would outperform Shock Index Pediatric Age-adjusted. METHODS: We analyzed a retrospective cohort of pediatric trauma patients (age 1 to 16 years old) in the American College of Surgeons Trauma Quality Programs Participant Use File from 2010 to 2018. The primary outcome measure was in-hospital mortality. The Shock Index Pediatric Age-adjusted was compared to an Advanced Trauma Life Support-based and a Pediatric Advanced Life Support-based shock index cutoff system. Our findings were subsequently confirmed with a separate, internal validation data set. RESULTS: A total of 598,830 Trauma Quality Programs Participant Use File patients were included, 0.9% (n = 5,471) of whom died. For mortality, the Advanced Trauma Life Support-based system yielded the highest positive predictive value (15.8%; 95% confidence interval 15.0%-16.7%) compared with the Pediatric Advanced Life Support-based system (4.3%; 95% confidence interval 4.1%-4.5%). Both the Advanced Trauma Life Support-based and Pediatric Advanced Life Support-based systems achieved higher positive predictive values compared to Shock Index Pediatric Age-adjusted (2.6%; 95% confidence interval 2.5%-2.7%). The negative predictive values were not clinically different. Our findings were validated using a separate internal trauma database, in which the positive predictive value for mortality of the Advanced Trauma Life Support-based system was significantly higher than Shock Index Pediatric Age-adjusted (18.2% [95% confidence interval: 8.2%-32.7%] vs 2.9% [95% confidence interval: 1.6%-5.0%], P < .05). CONCLUSION: Advanced Trauma Life Support and Pediatric Advanced Life Support-based shock index cutoffs achieved higher positive predictive values and similar negative predictive values compared to Shock Index Pediatric Age-adjusted for adverse outcomes in pediatric trauma.

Mortality and PICU Hospitalization Among Pediatric Gunshot Wound Victims in Chicago.

Firearm injury accounts for significant morbidity with high mortality among children admitted to the PICU. Understanding risk factors for PICU admission is an important step toward developing prevention and intervention strategies to minimize the burden of pediatric gunshot wound (GSW) injury. OBJECTIVES: The primary objective of this study was to characterize outcomes and the likelihood of PICU admission among children with GSWs. DESIGN SETTING AND PARTICIPANTS: Retrospective cohort study of GSW patients 0-18 years old evaluated at the University of Chicago Comer Children's Hospital Pediatric Trauma Center from 2010 to 2017. MAIN OUTCOMES AND MEASURES: Demographic and injury severity measures were acquired from an institutional database. We describe mortality and hospitalization characteristics for the cohort. We used logistic regression models to test the association between PICU admission and patient characteristics. RESULTS: During the 8-year study period, 294 children experienced GSWs. We did not observe trends in overall mortality over time, but mortality for children with GSWs was higher than all-cause PICU mortality. Children 0-6 years old experienced longer hospitalizations compared with children 13-16 years old (5 vs 3 d; p = 0.04) and greater frequency of PICU admission (83.3% vs 52.9%; p = 0.001). Adjusting for severity of illness, children less than 7 years old were four-fold more likely to be admitted to the PICU than children 13-16 years old (aOR range, 3.9-4.6). CONCLUSIONS AND RELEVANCE: Despite declines in pediatric firearm mortality across the United States, mortality did not decrease over time in our cohort and was higher than all-cause PICU mortality. Younger children with GSWs experience longer hospitalizations and require PICU care more often than older children. Our findings suggest that the youngest victims of firearm-related injury may be particularly at-risk of the long-term sequelae of critical illness and injury.

Higher Crystalloid Volume During Initial Pediatric Trauma Resuscitation is Associated With Mortality.

BACKGROUND: Historically, aggressive fluid resuscitation has been a cornerstone of management of hemorrhagic shock in pediatrics. Adult data suggest this strategy may be harmful. We sought to determine whether aggressive fluid resuscitation within the first hour of presentation to the emergency department in pediatric patients with trauma is associated with worse clinical outcomes. MATERIALS AND METHODS: We performed a retrospective cohort study from 2012 to 2017 at a single pediatric level 1 trauma center. We defined three patient cohorts: ≤ 20 cc/kg (reference), 20-40 (20.01 to 39.99) cc/kg, and ≥40 cc/kg of intravenous fluid (IVF) given in the first in-hospital hour. Covariates included age, injury severity score, shock index (adjusted for age), and mechanism of injury and were adjusted for with multivariable regression. The primary outcome was in-hospital mortality. RESULTS: A total of 1479 consecutive injured children were eligible for inclusion. One hundred ninety-four patients were excluded for missing IVF data, aged ≥16 y, having primary burns, or arriving pulseless. A total of 1285 patients met inclusion criteria (mean age 8.1 ± 5.5 y, male 64.5%). Higher rates of IVF administration were associated with mortality for both the 20-40 cc/kg (adjusted odds ratio (aOR) 2.96; 95% confidence interval (CI) 1.02-8.55; P = 0.045) and ≥40 cc/kg groups (aOR 6.26; 95% CI 1.79-21.83; P = 0.004). The ≥40 cc/kg group was associated with increased pediatric intensive care unit length of stay (aOR 2.20; 95% CI: 1.05-4.61; P = 0.036) and increased need for mechanical ventilation (aOR 3.79; 95% CI 1.62-8.87; P = 0.002). CONCLUSIONS: Greater than one 20 cc/kg IVF bolus in the first emergency department hour was associated with mortality with a dose-response relationship, even after adjusting for injury severity and initial hemodynamics. These results encourage further investigation into initial resuscitation strategies for injured children.
