Changes in Pediatric Non-accidental Trauma Emergency Department Visits During and Following the COVID-19 Lockdown.

A level 1 pediatric trauma registry database was examined for all non-accidental trauma (NAT) emergency department visits between 2016 and 2021, and average injury severity score assigned to those patients with physical injuries over 2019-2021. There was a decline in NAT visits in 2020 (267) from prior years (343 visits average over 2016-2019), with subsequent increase in 2021 (548). Injury severity score increased (ISS) in 2020 (7.3) when compared to 2019 (5.71), with a decline in average ISS in 2021 (5.42). This data highlights the potential for missed abuse during closures with increased detection following reopening. Our data regarding ISS demonstrates the pediatric population is at risk of more severe abuse during times of familial stress. We need increased awareness that periods of vulnerability to NAT exist, as seen during the COVID-19 pandemic.

Use of a Guide-wire as an Adjunct for the Safe Removal of a 'Stuck' Indwelling Central Venous Catheter at Risk for Breaking.

Port-based central venous catheters may remain indwelling for years with subsequent fibrosis resulting in a "stuck" catheter. At time of removal, this can lead to complications such as catheter fracture or require additional operative techniques for safe extraction. We present a case utilizing a protocol wherein a J-tip guidewire is placed to assist in removal. We believe this serves the following beneficial functions: Mechanically, as the catheter stretches and collapses upon retraction it distributes the force circumferentially along the length of the catheter as well as reduces angular kinking, mitigating stress points of fracture. Second, in case of fracture, the distal portion should remain intubated by the J-tip guidewire, reducing embolic potential. Third, it allows more facile percutaneous transvenous retrieval if indicated. Though this does not represent a perfect solution to the "stuck" catheter problem, this technique increases safety and efficacy of removal with easy application at minimal additional cost.

Incidental Preduodenal Portal Vein Causing Partial Duodenal Obstruction and Hypertrophied Pre-Pyloric Gastric Polyp.

Preduodenal portal vein (PDPV) is a rare congenital anomaly in which the portal vein lies anterior to the duodenum rather than its normal posterior position. It is a known rare cause of duodenal obstruction and can be associated with other anomalies such as malrotation with or without jejunal atresia. Presented is an incidentally found PDPV causing partial duodenal obstruction during exploration for the resection of a gastric mass and placement of open gastrostomy tube for feeding. This was managed with duodenoduodenostomy, re-creating normal anatomy with portal.

Tumors in the cauda equina: A SEER analysis of tumor types and predictors of outcome.

Caudaequinatumors are histologically diverse. International Classification of Diseases for Oncology (ICD-O3) confers dedicated site code (C72. 1) for cauda equina. This code is excluded during analyses of other primary spinal cord tumors. In this retrospective study, the Surveillance, Epidemiology and End Results (SEER) data for primary cauda equina tumors (PCET, C72. 1) excluding the tumors of spinal meninges (C70. 1) from 1992 to 2015 were reviewed. Demographic characteristics, tumor types, and clinical outcomes were analyzed using univariable analysis. Overall survival was estimated using Kaplan-Meier methods and compared for age, histology and treatment type. 293 patients with PCET met inclusion criteria. The most common tumors comprised schwannoma (32%), myxopapillary ependymoma (21%), malignant ependymoma (22%). The median age at diagnosis was 50 years (range < 1 year to 98 years), 57% of patients were males. 77% of the patients underwent surgery. Median follow up time for these patients was 70 months. Of the 293 patients, 250 (85%) were living at the end of 2015. The cause of death was tumor or CNS related in 15 patients. 136 patients were followed for <5 years, of which 102 were censored and 34 died (11.6%) before 5 years. Using univariable analysis, age at diagnosis (Hazard Ratio, HR 1.05; confidence interval, CI 1.03-1.07; p < 0.001), malignant tumor type (HR 2.88, CI 1.15-7.19, p = 0.0239) and absence of surgical intervention (HR 2.54, CI1.26-5.11, p = 0.0092) were predictors of increased mortality. Although most patients did well, older age and lack of surgical intervention were associated with worse survival.
