Objective: To compare the occurrence of fetal bradycardia in open versus fetoscopic fetal spina bifida surgery.

Methods: This is a single-institution retrospective cohort study of patients undergoing open (n = 25) or fetoscopic (n = 26) spina bifida repair between 2017 and 2022. From October 2017 to June 2020, spina bifida repairs were performed via an open classical hysterotomy, and from November 2020 to June 2022 fetoscopic repairs were performed following transition to this technique.

Needle Fetal Thoracoscopy: A Technique to Assist with Ultrasound-Guided Placement of Challenging Thoracoamniotic Shunts.

Introduction: Fetal thoracoamniotic shunts are common lifesaving interventions but frequently require replacement. Needle fetal thoracoscopy is a technique that uses standard thoracoamniotic shunt introducer sheaths to permit direct visualization and even instrument manipulation during shunt deployment to facilitate optimal positioning and primary shunt function in the most challenging cases.

Case Presentation: In this study, 5 patients who underwent needle fetal thoracoscopy-assisted thoracoamniotic shunt placement were reviewed.

Management of undifferentiated embryonal sarcoma of the liver: A Pediatric Surgical Oncology Research Collaborative study.

Background: Undifferentiated embryonal sarcoma of the liver (UESL) is a rare tumor for which there are few evidence-based guidelines. The aim of this study was to define current management strategies and outcomes for these patients using a multi-institutional dataset curated by the Pediatric Surgical Oncology Research Collaborative.

Methods: Data were collected retrospectively for patients with UESL treated across 17 children's hospitals in North America from 1989 to 2019.

Ex-Utero Intrapartum Treatment-to-Airway for Obstructing Fetal Neck Masses: A Singular Methodology for Monochorionic and Dichorionic Twin Pregnancies.

Fetal airway obstruction in one twin of a diamniotic pregnancy presents unique challenges. Very few cases of ex-utero-intrapartum-treatment (EXIT) procedures for twin pregnancy have been reported and only in dichorionic pregnancies. We report a singular methodology for EXIT-to-airway procedures in two pregnancies involving monochorionic and dichorionic twins.

Measuring the Efficacy of Thymectomy for Pediatric Myasthenia Gravis Across Tertiary Children's Hospitals.

Background: Thymectomy is a treatment for pediatric myasthenia gravis, but the efficacy over time is unknown. Multi-institutional data are also lacking. Therefore, the objective of this study was to determine the efficacy of thymectomy for pediatric myasthenia gravis using medication burden and health care utilization as proxies for disease severity.

Nonparasitic Splenic Cysts in Children: Outcomes after Sclerotherapy or Surgical Resection as Initial Management.

Management of splenic cysts in children remains undefined. Sclerotherapy is an innovative, less invasive treatment. This study examined the safety and preliminary effectiveness of sclerotherapy for splenic cysts in children compared with those of surgical treatment.

CD4 and IL-2 mediated NK cell responses after COVID-19 infection and mRNA vaccination in adults.

A detailed understanding of protective immunity against SARS-CoV-2 is incredibly important in fighting the pandemic. Central to protective immunity is the ability of the immune system to recall previous exposures. Although antibody and T cell immunity have gained considerable attention, the contribution of the NK cell compartment to immune recall and protection from SARS-CoV-2 has not been explored.

Expedited Surgical Care of Appendicitis is Associated With Improved Resource Utilization.

Introduction: Appendectomy for acute appendicitis is the most common pediatric intra-abdominal operation. Current literature supports the notion that modest in-hospital, preoperative delays are not associated with greater patient morbidity. However, there is less certainty regarding the role that hour-of-presentation plays in determining the timing of surgery.

The interplay between prenatal liver growth and lung development in congenital diaphragmatic hernia.

Objective: Liver herniation is a known risk factor for increased severity in CDH and is associated with clinically significant pulmonary hypoplasia and pulmonary hypertension. Better studies are needed to understand the growth of the herniated liver compared to the liver that remains in the abdomen and how this liver growth then affects lung development. Serial hi-resolution fetal MRI enables characterization of liver growth throughout gestation and examination of macroscopic features that may regulate liver growth.

The costs and benefits of emergent surgical workflow for acute appendicitis in children.

Background: Controversy exists regarding how operative timing affects patient safety and resource utilization for acute appendicitis. Over 3 years, our institution trialed efforts to optimize appendectomy workflow. Our aim is to describe the ramifications of expediting appendectomy and implementing standardized protocols relative to historic controls.

Management of broncho-esophageal fistula after button battery ingestion.

Button battery ingestion can cause serious injury or death in young children who cannot communicate symptoms. An 18-month-old male presented after his mother noted drooling, nonbilious emesis and a metallic smell to his breath. He underwent rigid esophagoscopy and a 3-V 20-mm button battery was removed.

Pediatric palliative care and surgery.

Care for pediatric patients with serious or potentially life-limiting illness involves the interplay of multiple medical and surgical teams within the hospital. Pediatric surgeons are capable of performing procedures that can improve the quality of life for children facing serious illness, but which also carry the potential for significant risk and burden. Patients and families are often faced with decisions about invasive surgical procedures and interventions, stressing the need for seamless collaboration between palliative care and surgical providers.

Improving trauma tertiary survey performance and missed injury identification using an education-based quality improvement initiative.

Background: Performance of a trauma tertiary survey (TTS) reduces rates of missed injuries, but performance has been inconsistent at trauma centers. The objectives of this study were to assess whether quality improvement (QI) efforts would increase the frequency of TTS documentation and determine if TTS documentation would increase identification of traumatic injuries. Our hypothesis was that QI efforts would improve documentation of the TTS.

Computed Tomography of Adult Rhinosinusitis.

Rhinosinusitis involves symptomatic inflammation of the paranasal sinuses. This common condition affects approximately 1 in 7 adults in the United States and is associated with significant morbidity and financial costs. Although rhinosinusitis primarily is a clinical diagnosis, medical imaging plays a unique role in sinusitis diagnosis and treatment, particularly in presurgical planning.

Neosuture formation after endoscope-assisted craniosynostosis repair.

OBJECTIVE The goal of this study was to identify the rate of neosuture formation in patients with craniosynostosis treated with endoscope-assisted strip craniectomy and investigate whether neosuture formation in sagittal craniosynostosis has an effect on postoperative calvarial shape. METHODS The authors retrospectively reviewed 166 cases of nonsyndromic craniosynostosis that underwent endoscope-assisted repair between 2006 and 2014. Preoperative and 1-year postoperative head CT scans were evaluated, and the rate of neosuture formation was calculated.

Antibody mediated therapy targeting CD47 inhibits tumor progression of hepatocellular carcinoma.

Human hepatocellular carcinoma (HCC) has a high rate of tumor recurrence and metastasis, resulting in shortened survival times. The efficacy of current systemic therapies for HCC is limited. In this study, we used xenograft tumor models to investigate the use of antibodies that block CD47 and inhibit HCC tumor growth.

Application of the social ecological model in folic acid public health initiatives.

All women of childbearing age who are capable of becoming pregnant should consume 0.4 mg/400 microg of folic acid daily. Folic acid decreases the incidence of neural tube defects in newborns.

Disability and the practice of public history: an introduction.

Museums, exhibitions, and public history have long engaged with the subject matter of disability. Shared social conventions and exhibition traditions about people with disabilities--the common stereotypes of people as persevering heroes or objects of pity--have often led to skewed and inaccurate historical presentations. The medical model of disability, equally strong in framing disability, has also reduced the range of possibilities for including content for the public.
