AiRDose: Developing and Validating an Augmented Reality Smartphone Application for Weight Estimation and Dosing in Children.

Objectives: Inaccurate weight estimation is a contributing factor to medical error in pediatric emergencies, especially in the prehospital setting. Current American Heart Association guidelines recommend the use of length-based weight estimation tools such as the Broselow tape. We developed the AiRDose smartphone application that uses augmented reality to provide length-based weight estimates, as well as medication dosing, defibrillation energy, and equipment sizing recommendations; AiRDose was programmed to use Broselow conversions to obtain these estimates.

Features of COVID-19 post-infectious cytokine release syndrome in children presenting to the emergency department.

The 2019 coronavirus disease (COVID-19) has not appeared to affect children as severely as adults. However, approximately 1 month after the COVID-19 peak in New York City in April 2020, cases of children with prolonged fevers abruptly developing inflammatory shock-like states have been reported in Western Europe and the United States. This case series describes four previously healthy children with COVID-19 infection confirmed by serologic antibody testing, but negative by nasopharyngeal RT-PCR swab, presenting to the Pediatric Emergency Department (PED) with prolonged fever (5 or more days) and abrupt onset of hemodynamic instability with elevated serologic inflammatory markers and cytokine levels (IL-6, IL-8 and TNF-α).

Sleep and Breathing the First Night After Adenotonsillectomy in Obese Children With Obstructive Sleep Apnea.

Study Objectives: There are few studies measuring postoperative respiratory complications in obese children with obstructive sleep apnea (OSA) undergoing adenotonsillectomy (AT). These complications are further compounded by perioperative medications. Our objective was to study obese children with OSA for their respiratory characteristics and sleep architecture on the night of AT.

Primary hyperoxaluria: spectrum of clinical and imaging findings.

Primary hyperoxaluria is a rare autosomal recessive inborn error of metabolism with three known subtypes. In primary hyperoxaluria type 1, the most common of the subtypes, a deficiency in the hepatic enzymes responsible for the metabolism of glycoxylate to glycine, leads to excessive levels of glyoxylate, which is converted to oxalate. The resultant elevation in serum and urinary oxalate that characterizes primary hyperoxaluria leads to calcium oxalate crystal deposition in multiple organ systems (oxalosis).
