Evaluation of Serotonin Release Assay and Enzyme-Linked Immunosorbent Assay Optical Density Thresholds for Heparin-Induced Thrombocytopenia in Patients on Extracorporeal Membrane Oxygenation.

Objectives: Heparin-induced thrombocytopenia is a recognized concern in patients on extracorporeal life support. The purpose of this study was to evaluate the applicability of an enzyme-linked immunosorbent assay optical density threshold less than 1 to rule out heparin-induced thrombocytopenia in patients on extracorporeal membrane oxygenation.

Design: Retrospective, single-center study.

Non-Radiographic Severity Measurement of Pectus Excavatum.

Background: To avoid the radiation exposure of CT imaging and the expense of CT or MRI studies, we sought to develop a non-radiographic severity measurement of pectus excavatum based on 3D photogrammetric imaging.

Methods: Over 28 mo, ten consecutive patient volunteers with pectus excavatum underwent 3D stereophotogrammetric imaging. The surface width to surface depth ratio (Surface Lengths Pectus Index), the chest deformity's surface area to total chest surface area (Pectus Surface Area Ratio), and the chest deformity's volume to total chest volume (Pectus Volume Ratio) were calculated.

The impact of morbid obesity on solid organ injury in children using the ATOMAC protocol at a pediatric level I trauma center.

Introduction: Obesity is an epidemic in the pediatric population. Childhood obesity in trauma has been associated with increased incidence of long-bone fractures, longer ICU stays, and decreased closed head injuries. We investigated for differences in the likelihood of failure of non-operative management (NOM), and injury grade using a subset of a multi-institutional, prospective database of pediatric patients with solid organ injury (SOI).
