Article Synopsis
  • The study aimed to evaluate the effectiveness of MRI in predicting ovarian cancer in young patients compared to other diagnostic tools like ultrasounds and tumor markers.
  • Out of 1,053 patients, 10% were found to have malignancies, revealing MRI's sensitivity and specificity to be 60% and 94% respectively, while ultrasound was less sensitive but more specific.
  • The results suggest that MRI shows better sensitivity in ambiguous cases compared to ultrasound, and both MRI and tumor markers tend to agree, indicating that a combined approach could optimize preoperative assessment.

Objectives: Population health experts have described the link between social factors and health, but few studies link specific social needs to disease processes. Nationwide Children's Hospital implemented a universal, annual screener for social determinants of health (SDH) in 2018. Early analyses have shown that patients identifying an SDH need were more likely to have an emergency department (ED) or inpatient stay.

Importance: Work-related musculoskeletal disorders are common among otolaryngologists and can be associated with decreased productivity, missed workdays, and reduced quality of life. Ergonomic risk for surgeons is elevated during common otolaryngology procedures; current ergonomic interventions lack the ability to provide real-time feedback. The ability to quantify and mitigate ergonomic risk during surgery may reduce work-related musculoskeletal disorders.

Study Objective: To examine the recurrence rates of pediatric benign ovarian neoplasms METHODS: A retrospective review of females up to 21 years of age who underwent surgery for a benign ovarian neoplasm at 8 pediatric hospitals from January 2010 through December 2016 was conducted. Data include primary operation details, follow-up imaging, and reoperation details.

Results: Four hundred and twenty-six females were included in our cohort, with a median age of 15 years at the time of the primary operation.

Study Objective: To evaluate failure of initial operative therapy (incomplete tumor removal) of ovarian-sparing surgery for pediatric benign ovarian neoplasms.

Methods: A retrospective review of patients up to 21 years of age who underwent ovarian-sparing surgery for a benign ovarian neoplasm from 2010 to 2016 at 8 pediatric hospitals was conducted. Failure of initial operative therapy is defined as a radiologically suspected or pathologically confirmed ipsilateral lesion with the same pathology as the primary neoplasm within 12 weeks of the initial operation.

Introduction: Disparities in surgical management have been documented across a range of disease processes. The objective of this study was to investigate sociodemographic disparities in young females undergoing excision of a breast mass.

Methods: A retrospective study of females aged 10-21 y who underwent surgery for a breast lesion across eleven pediatric hospitals from 2011 to 2016 was performed.

Background: The objective of this study was to determine the rates at which gynecologic history and related exams are performed among adolescent females presenting with abdominal pain and whether the rates differ between patients seeking care at a pediatric compared with a general emergency department (ED).

Methods: We conducted a retrospective cohort study of female patients aged 12-21 years who presented to the ED for a chief complaint of abdominal pain at either a single academic children's ED or a single general academic ED during 2016. We examined differences in the rates of gynecologic history and related exams between institutions, before and after adjustment with inverse probability weights.

Background: With increased surgeon comfort using laparoscopy, we hypothesized resection of pediatric ovarian dermoids using laparoscopy would yield a shorter length of stay and no increase in morbidity or recurrence compared to laparotomy.

Methods: A retrospective review was performed amongst eleven pediatric hospitals. Patients aged 2 to 21 who underwent resection of an ovarian dermoid from 2010 to 2020 were included.

Study Objective: To assess the preoperative imaging impression and surgeon diagnostic accuracy for pediatric ovarian mature cystic teratomas (MCTs) DESIGN: Retrospective review SETTING: Eleven pediatric hospitals PARTICIPANTS: Patients ages 2 to 21 who underwent surgical management of an ovarian neoplasm or adnexal torsion with an associated ovarian lesion INTERVENTION: None MAIN OUTCOME MEASURES: Preoperative imaging impression, surgeon diagnosis, tumor markers, and pathology RESULTS: Our cohort included 946 females. Final pathology identified 422 (45%) MCTs, 405 (43%) other benign pathologies, and 119 (12%) malignancies. Preoperative imaging impression for MCTs had a 70% sensitivity, 92% specificity, 88% positive predictive value (PPV), and 79% negative predictive value (NPV).

Background: Despite increased utilization of robotic-assisted surgery in the pediatric population during the past decade, reports of comparative analysis between robotic surgery and laparoscopic surgery are lacking. Our aim was to evaluate outcomes between pediatric robotic-assisted cholecystectomy (RC) and laparoscopic cholecystectomy (LC).

Methods: A single institution retrospective analysis of 299 patients undergoing either RC or LC, between January 2015 and December 2018 was performed.

Objectives: The objective of this study is to examine the impact that an institution-wide policy to reduce radiation exposure in pediatric patients had on the use of computed tomography (CT) imaging in children presenting with suspected peritonsillar abscess (PTA)1.

Methods: A single institution retrospective review was conducted for all pediatric patients under the age of 18 who presented to the emergency department with suspected PTA over a ten-year period. Patients were divided into two groups; those that presented during the years prior to policy implementation and those that presented during the years following.

Background: Endoscopic airway measurement (EAM) combines optical endoscopic instruments with open source image processing to accurately obtain airway dimensions. Preclinical models have demonstrated EAM as an accurate technique of airway measurement with the added advantage of characterizing multilevel stenosis, non-circular lesions, and distal obstruction. The aim of this prospective clinical study was to compare EAM to airway measurements obtained from endotracheal tube approximation (ETTA) during pediatric aerodigestive evaluation and to evaluate reproducibility of EAM across practitioners.

Article Synopsis
  • Laser hair depilation shows potential to reduce recurrence rates in pilonidal sinus disease based on a review of existing studies.
  • The analysis included 35 studies, with varying methods, patient numbers, and follow-up times, highlighting a recurrence rate between 0% and 28%.
  • While the results suggest laser treatments may be beneficial, the studies' diversity and limited scope call for further research to establish broader conclusions on its effectiveness.
