Critical elements in the operative management of pediatric malignant ovarian germ cell tumors.

Performance of the appropriate operation is highly important to ensure that any patient with a suspected ovarian germ cell tumor receives optimal therapy that prioritizes cure while simultaneoulsy minimizing risk of short and long-term toxicities of treatment. The following critical elements of any operative procedure performed for a suspected pediatric or adolescent ovarian germ cell tumor are reviewed: 1. Complete resection of the tumor via ipsilateral oophorectomy while avoiding tumor rupture and spillage, and 2. Performance of complete intraperitoneal staging at the time of initial tumor resection.

Costs and recurrence of inguinal hernia repair in premature infants during neonatal admission.

BACKGROUND: Timing of inguinal hernia repair (IHR) in premature infants remains variable, yet the impact of IHR timing on procedure costs and recurrence is unclear. We sought to compare cost and recurrence rates of IHR in premature infants based on timing of repair. METHODS: We performed a retrospective cohort study using MarketScan insurance claims data from 2007 to 2018 to evaluate IHR occurring within 365 days of birth in preterm infants (gestational age [GA]<37 weeks at birth). Patients were stratified based on timing of IHR: those occurring during and after neonatal discharge. Hernia recurrences within one year following IHR were identified. Patient demographic characteristics and costs were compared between groups. Time to recurrence and cumulative recurrence hazards were estimated using Kaplan Meier analysis and Cox proportional hazards regression. RESULTS: We identified 3,662 preterm infants with IHR within 365 days of birth; 1,054(28.8%) occurred early. Infants with IHR during NICU stay were more likely to have GA at birth≤32 weeks (74.7% vs. 37.2%; p<0.01) and birthweight<1500 g (83.0% vs. 40.3%; p<0.01) compared to post-NICU IHR. The hernia recurrence rate was higher and total procedure costs lower in early IHR. Early IHR (HR:1.86, 95% CI: 1.56-2.22), incarcerated/strangulated hernia (HR:1.86, 95% CI:1.49-2.32), GA≤32 weeks (HR: 1.40, 95% CI: 1.19-1.65), and congenital anomalies (HR: 1.32, 95% CI: 1.12-1.57) were predictors of hernia recurrence. CONCLUSION: Using insurance claims data, IHR performed during initial neonatal admission was associated with lower cost, but higher recurrence rate, when compared to delayed repairs in preterm infants. TYPE OF STUDY: Retrospective study LEVEL OF EVIDENCE: Level III.

Cost of Pediatric Trauma: A Comparison of Non-Accidental and Accidental Trauma in Pediatric Patients.

BACKGROUND: Nonaccidental trauma (NAT) affects >100,000 children in the United States every year and is associated with significant mortality and morbidity. Little is known about the financial burden of NAT, particularly in comparison to accidental trauma (AT). We sought to compare hospital charges and outcomes between children presenting with NAT and AT. METHODS: Pediatric (<16 y) trauma hospitalizations from 2006 to 2018 were identified using the Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample (NIS) and Kid's Inpatient Sample (KID) databases. Hospitalizations were identified as NAT or AT based on ICD codes. Discharge weights were used to obtain national estimates and standardize them across the different sampling structures. Outcomes (hospital charges, length of stay (LOS), and mortality) were compared, and multivariate regression analyses were used to assess independent predictors of hospital charges and mortality. RESULTS: Fifty-eight Thousand Two Hundred Seventy-five pediatric hospitalizations were included with 17,954 (0.3%) categorized as NAT. Children with NAT were younger, more female, less likely to identify as White, and more under public insurance than those with AT. Hospital charges were significantly higher in patients with NAT ($27,100 versus $19,900, P < 0.0001). Mortality (4.9% versus 0.0%, P < 0.0001) and LOS (3.2 d versus 1.5 d, P < 0.0001) were significantly higher among patients with NAT. Multivariable regression analyses identified NAT as a predictor of higher hospital charges, mortality, and LOS. CONCLUSIONS: Nonaccidental trauma in pediatric patients is associated with significantly higher hospital charges, mortality, and LOS than accidental trauma. Ongoing research focused on the relative impact of known risk factors and resource utilization is needed.

Surgical outcomes and survival of adrenocortical carcinoma between children and adults.

INTRODUCTION: Adrenocortical carcinoma (ACC) is associated with poor outcomes. We compared surgical outcomes between children and adult; and identified factors independently associated with survival. METHODS: Using the National Cancer Database, children and adults with ACC who underwent surgery between 2004 and 2016 were identified. We compared outcomes and survival between groups. Cox regression analysis was performed to identify predictors of survival. RESULTS: Of 2553 patients, 2.8% were children. A higher proportion of children were Hispanic (19.1%vs.6.6%) and covered by government insurance (45.1%vs.35.8%) than adults. More pediatric patients received lymphadenectomy and chemotherapy than adults. Pediatric patients had better survival at 1 -(91.4%; 95%CI: 81.2%-96.0% vs.79.6%; 95%CI: 77.9%-81.1%) and 5-years (60.6%; 95%CI:47.5%-71.3% vs.44.9%; 95%CI 42.7%- 47.0) (p = 0.0016). Age≥18 (HR: 2.21(1.50-3.27)), metastatic disease at diagnosis (HR: 3.51(3.04-4.04)), and receipt of lymphadenectomy (HR: 1.30(1.14-1.48)) were independently associated with worse survival. CONCLUSIONS: Children with ACC had better survival than adults. Factors independently associated with worse survival included older age, metastatic disease, and receipt of lymph node surgery.
