Computed tomography-guided percutaneous cryoablation of hereditary adrenal pheochromocytoma in three patients.

OBJECTIVES: Pheochromocytomas (PHEO) are neuroendocrine tumors rarely diagnosed in children. We are reporting on the management challenges of three adolescent patients who present with hereditary PHEO. CASE PRESENTATION: The index patient and his male sibling presented with bilateral PHEO, while a third patient presented with a unilateral PHEO, all associated with von Hippel-Lindau (VHL) syndrome. The patients were treated with computed tomography (CT)-guided percutaneous cryoablation (CRA) of the adrenal lesions, with varying degrees of success. CONCLUSIONS: CT-guided percutaneous CRA of hereditary PHEO has not been reported in the pediatric population and may represent a novel treatment strategy that reduces the risk of intraprocedural complications and adrenal insufficiency (AI).

Misplaced Evidence, Missed Opportunities: Protocols for Handling Ballistic Evidence in Pediatric Patients.

BACKGROUND: Gun-related injury is now the number one cause of death in pediatric trauma patients. Many hospitals lack dedicated forensic nurses or updated protocols for handling ballistic evidence. Evidence not collected, handled improperly, or misplaced may deny a victim the basic human right to justice. OBJECTIVE: This article aims to describe an initiative to highlight the importance of proper management of ballistic evidence and to educate medical providers on best practices for the documentation, handling, removal, and transfer of ballistic evidence. METHODS: After discovering 24 "orphaned" bullets and bullet fragments in our hospital that had not been turned over to law enforcement, we sought to turn in evidence to the proper authorities and implement protocols to prevent this error in the future. New protocols were written by forensic staff, and education on new protocols was provided via in-person training, grand rounds, emails, and other collaborative initiatives. RESULTS: Evidence was matched to police reports using the patient name and date of birth on evidence labels. The median (interquartile range [IQR]) time of lost ballistic evidence was 1,397 (903, 1604) days, with the oldest bullet removed in 2015. All bullets were successfully returned to law enforcement with a median (IQR) time from bullet discovery to collection of 78 (78, 174) days. CONCLUSIONS: Ballistic evidence handling protocols are essential for all hospitals. Dedicated, trained forensic staff should be employed to ensure proper evidence handling.

Establishing Shock Index, Pediatric Age-Adjusted (SIPA) Cut Points in Trauma Patients Under 1 Year of Age.

PURPOSE: Shock Index (SI) is used to predict injury severity and adverse outcomes in trauma patients, but age-adjusted shock index (SIPA) has superior performance in pediatric patients over the age of 1 year. SIPA scores under the age of 1 have not been well studied. This project aimed to establish and evaluate SIPA cut point data points for patients under 1 year of age. METHODS: Using age-based vital signs, we developed cut point values for patients under 1 year old using our institutional trauma data. All trauma patients under the age of 12 months were included, and clinical outcomes were recorded. SIPA cut points were defined using age specific vital sign limits (SIPA-VS) and tested against optimal cut points defined by ROC analysis (SIPA-ROC) and a cut point of 1.2 (SIPA-Nordin), which is used for patients ages 1-4 years. Student's t-test, chi-square tests, ANOVA, and test characteristics were used to analyze groups. RESULTS: A total of 609 pediatric trauma patients under the age of 12 months were identified from 2018 to 2022. SIPA scores were calculated for 483 patients. There were 406 patients with blunt trauma and 17 with penetrating. SIPA-Nordin was elevated in 81.6% (n = 397) of patients, compared to SIPA-VS 21% (n = 101) and SIPA-ROC 31% (n = 150). In comparison to SIPA-Nordin, both SIPA-VS and SIPA-ROC score exhibited superior specificity and negative predictive values (NPV) for multiple outcomes. Elevated SIPA-ROC scores had statistically significant associations with ICU admission, mechanical ventilation, severe anemia, transfusion during hospital admission, and in-hospital mortality. CONCLUSION: SIPA is a useful tool in identifying patients at risk for several complications of severe traumatic injury. SIPA cut points had high NPV and specificity for many outcomes. This study proposes cut point values that may aid in clinical decision-making for trauma patients under 1 year of age.Level of Evidence: Level IV Retrospective Review.

Factors Associated With Early Discharge in Pediatric Trauma Patients Transported by Rotor: A Retrospective Analysis.

OBJECTIVE: Helicopter emergency medical services (HEMS) play a crucial role in providing timely transport for pediatric trauma patients. This service carries the highest risk of any mode of medical transport and a high financial burden, and patient outcomes are seldom investigated. This study evaluated the characteristics of pediatric trauma patients discharged within 24 hours after transport by HEMS. METHODS: This was a single-center, retrospective analysis on pediatric trauma patients transported by HEMS from 2019 to 2022. Analyses were performed to identify factors associated with discharge within 24 hours. Factors analyzed included vital signs, Shock Index, Pediatric Age-Adjusted scores, management details, and clinical outcomes. RESULTS: A total of 466 pediatric trauma patients were transported by HEMS, including 171 patients (36.7%) who were discharged within 24 hours. There were no differences in the rates of blunt and penetrating injury (P = .583). Patients discharged within 24 hours were more likely to have a higher Glasgow Coma Scale score (14 vs. 11, P < .001) and a lower Injury Severity Score (4.9 vs. 14.7, P < .001), required less prehospital fluid resuscitation (5.5 vs. 11.7 mL/kg, P = .039), and had higher levels of serum calcium (9.3 vs. 8.9 mg/dL, P < .001). They were also less likely to meet criteria for level 1 trauma activation (13.0% vs. 40%, P < .001) or to require prehospital respiratory support of any kind (4.1% vs. 31.1%, P < .001). After arrival at the hospital, they were less likely to require blood transfusions (2.9% vs. 29.8%, P < .001) or tranexamic acid (2.9% vs. 11.5%, P = .001). CONCLUSION: Trauma patients with a high Glasgow Coma Scale score and a low Injury Severity Score who do not require critical care or meet the criteria for high-level trauma activation may be suitable for transportation with lower acuity. Further studies aimed at improving triage and implementing improved criteria for the use of HEMS are paramount.
