Inter-Rater Reliability of Hounsfield Units as a Measure of Bone Density: Applications in the Treatment of Thoracolumbar Fractures.

Objective: The study sought to investigate the reliability of computed tomography (CT)-derived Hounsfield unit (HU) measurements and ascertain the correlation between HU with quantitative CT (qCT)-derived bone mineral density (BMD) in cases of traumatic thoracolumbar fracture, based on native CT scans.

Methods: This study is a retrospective cross-sectional analysis of data sets from patients who received native CT scans and bone mineral density measurements (qCT) of the same vertebral body. Two different CT scanner models were used.

Insufflation vs intubation during esophagogastroduodenoscopy in children.

Objectives: We compared adverse airway events during esophagogastroduodenoscopy (EGD) in children managed with insufflation vs intubation.

Background: Optimum airway management during EGD in children remains undecided.

Methods/materials: Following IRB approval and written informed parental consent, children between 1 and 12 years of age presenting for EGD were randomized to airway management with insufflation (Group I), intubation/awake extubation (Group A), or intubation/deep extubation (Group D).

Real-time assessment of perioperative behaviors in children and parents: development and validation of the perioperative adult child behavioral interaction scale.

Background: Behavior in response to distressful events during outpatient pediatric surgery can contribute to postoperative maladaptive behaviors, such as temper tantrums, nightmares, bed-wetting, and attention seeking. Currently available perioperative behavioral assessment tools have limited utility in guiding interventions to ameliorate maladaptive behaviors because they cannot be used in real time, are only intended to be used during 1 phase of the experience (e.g.
