Burden of pilonidal disease and improvement in quality of life after treatment in adolescents.
Pediatric surgery international
PURPOSE: Pilonidal Disease (PD) affects adolescents in different aspects. We hypothesized that patients with different gender, ethnicity, and age have different quality of life (QOL) measurements which could improve with minimally invasive treatment (MIT).METHODS: 131 PD patients underwent MIT (laser epilation±trephination) from 2019 to 2021. Patients' demographics were recorded. Before and after MIT, patients received QOL questionnaire consisting of four categories: daily activities, sports participation, school/work attendance, and socializing. Data were analyzed using Student and multivariate t test. P<0.05 was considered statistically significant.RESULTS: 101 (51 male, 50 female) patients were included. 30 patients with incomplete data were excluded. 54% of patients were<18years old. 47.5% were Hispanic. Median symptom duration prior to presentation was 5.4 (1.3-15) months. Prior to MIT, patients' ability to perform daily activities, participate in sports, attend school/work, and socialize was moderately or severely impacted in 66%, 57%, 45%, and 23% of respondents, respectively; after MIT, only 7%, 8%, 2%, and 4% were affected (p<0.01). Recurrence rate was 6%. Pre-MIT, older patients and non-Hispanics reported worse impact on their QOL. Symptom duration or PD recurrence did not correlate with patient's pre- or post-MIT QOL.CONCLUSION: Patients' ethnicity and age impacted QOL in PD. All patients' QOL significantly improved with MIT. Considering the importance of socializing, playing sports, and school/work attendance in adolescents, our study highlights importance of early treatment of PD.

The novel application of an emerging device for salvage of primary repair in high-risk complex esophageal atresia.
Journal of pediatric surgery
Preservation of native esophagus is a tenet of esophageal atresia (EA) repair. However, techniques for delayed primary anastomosis are severely limited for surgically and medically complex patients at high-risk for operative repair. We report our initial experience with the novel application of the Connect-EA, an esophageal magnetic compression anastomosis device, for salvage of primary repair in 2 high-risk complex EA patients. Compassionate use was approved by the FDA and treating institutions.Two approaches using the Connect-EA are described - a totally endoscopic approach and a novel hybrid operative approach. To our knowledge, this is the first successful use of a hybrid operative approach with an esophageal magnetic compression device.Salvage of delayed primary anastomosis was successful in both patients. The totally endoscopic approach significantly reduced operative time and avoided repeat high-risk operation. The hybrid operative approach salvaged delayed primary anastomosis and avoided cervical esophagostomy.The Connect-EA is a novel intervention to achieve delayed primary esophageal repair in complex EA patients with high-risk tissue characteristics and multi-system comorbidities that limit operative repair. We propose a clinical algorithm for use of the totally endoscopic approach and hybrid operative approach for use of the Connect-EA in high-risk complex EA patients.

Epidemiology of pediatric trauma during the COVID-19 pandemic shelter in place.
Surgery open science
2021; 6: 5-9
Introduction: The first COVID-19 cases occurred in the US in January of 2020, leading to the implementation of shelter in place. This study seeks to define the impact of shelter in place on the epidemiology of pediatric trauma.Methods: We examined pediatric trauma admissions at 5 Level 1 and 1 Level 2 US pediatric trauma centers between January 1 and June 30, 2017-2020. Demographic and injury data were compared between pre- and post-shelter in place patient cohorts.Results: A total of 8772 pediatric trauma activations were reviewed. There was a 13% decrease in trauma volume in 2020, with a nadir at 16 days following implementation of shelter in place. Injury severity scores were higher in the post-shelter in place cohort. The incidence of nonmotorized vehicle accidents and gunshot wounds increased in the post-shelter in place cohort.Conclusion: We found an overall decrease in pediatric trauma volume following shelter in place. However, injuries tended to be more severe. Our findings help inform targeted injury prevention campaigns during future pandemics.

Serial Reduction of an Extremely Large Gastroschisis using Vacuum-Assisted Closure.
European journal of pediatric surgery reports
2018; 6 (1): e97–e99
We herein describe a case of serial reduction of an extremely large and complex gastroschisis using vacuum-assisted closure (VAC) therapy in a boy born at 35 5/7 weeks' gestation. A spring-loaded silicone silo was placed at birth. By day of life (DOL) 22, minimal visceral contents had been reduced, and the silo was difficult to maintain due to the size of the fascial defect and loss of abdominal domain. A bespoke VAC dressing was constructed, and biweekly dressing changes allowed gradual reduction of the gastroschisis until the viscera were consolidated. By DOL 50, the viscera were completely reduced, and VAC therapy was discontinued. Feeds were commenced on DOL 57 and increased to goal by DOL 86. The baby was discharged home on DOL 115. We conclude that VAC dressings can be used to aid gradual reduction of an extremely large gastroschisis, particularly in medical fragile infants.

A COMPARISON OF ACCIDENTAL AND NONACCIDENTAL TRAUMA: IT IS WORSE THAN YOU THINK
JOURNAL OF EMERGENCY MEDICINE
2015; 48 (3): 274-279
Child abuse, or nonaccidental trauma (NAT), is a major cause of pediatric morbidity and mortality, and is often unrecognized. Our hypothesis was that injuries due to accidental trauma (AT) and NAT are significantly different in incidence, injury, severity, and outcome, and are often unrecognized.Our aim was to carry out an examination of the differences between pediatric injuries due to AT and NAT regarding incidence, demographics, injury severity, and outcomes.A 4-year retrospective review of the Trauma Registry at Children's Medical Center Dallas, a large Level I pediatric trauma center, comparing incidence, age, race, trauma activation, intensive care unit (ICU) need, Injury Severity Score (ISS), and mortality between AT and NAT patients was carried out.There were 5948 admissions, 92.5% were AT and 7.5% were NAT victims. The NAT patients were younger (1.8 ± 3.3 years vs. 6.8 ± 4.2 years for AT patients; p < 0.01), more often required an ICU stay (NAT 36.5% vs. 13.8% for AT patients; p < 0.0001), and had a higher ISS 14.0 ± 9.7 vs. 7.5 ± 7.2; p < 0.0001). The mortality rate in NAT was 8.9% vs. 1.4% for AT (p < 0.001). Of the 40 NAT patients who ultimately died, 17.5% were not initially diagnosed as NAT.NAT victims differ significantly from the AT patients, with a greater severity of injury and a 6-fold higher mortality rate. Delayed recognition of NAT occurred in almost 20% of the cases. It is generally accepted that NAT is underestimated. Its increased mortality rate and severity of injury are also not well recognized compared to the typical pediatric trauma child.
