Orbital Mass Identified With Point-of-Care Ultrasound in a Child Presenting With Eyelid Swelling.

ABSTRACT: Point-of-care ultrasound was used in a child presenting to the emergency department with progressively worsening left eyelid swelling. The early use of ultrasound was helpful in detecting a soft tissue mass that is exhibiting pressure effect on the eyeball. Point-of-care ultrasound helped expedite advanced imaging and consultation with the specialist. The patient eventually had a biopsy and was diagnosed with idiopathic orbital inflammation.

Variability in Point-of-Care Lung Ultrasound Findings in Pediatric COVID-19 Patients: A Multicenter Case Series.

ABSTRACT: Point-of-care ultrasound (POCUS) has been described as a useful tool for identification of coronavirus disease 2019 (COVID-19) in adults and children. Although several case reports describe POCUS findings in children with COVID-19, to our knowledge, there have been no published multicenter case series describing the large heterogeneity in lung POCUS findings in pediatric COVID-19. This series includes 7 symptomatic patients with COVID-19 who had a lung POCUS performed at 6 institutions by pediatric emergency attendings and fellows. The findings were variable, ranging from no findings to the appearance of B-lines, pleural abnormalities, consolidations, and a pleural effusion. Further studies are needed to improve our understanding, characterization, and prognostic correlation of POCUS findings in this novel disease in children.

Virtual Reality vs. High-Fidelity Mannequin-Based Simulation: A Pilot Randomized Trial Evaluating Learner Performance.

Background Virtual Reality (VR) simulation has been found to be useful in learning technical and non-technical skills. However, empirical data about its efficacy in clinical education are limited. This pilot study compares the efficacy of VR to mannequin-based simulation for learners managing status epilepticus (SE). Methods Pediatric and emergency medicine interns at an academic tertiary care referral center were randomized to either VR (intervention, using an Oculus RiftⓇ (Occulus from Facebook, Facebook Inc., USA)) or mannequin-based (control) simulation for the same SE scenario. The control group participated in two mannequin-based simulation sessions while the intervention group had a VR session followed by a mannequin-based session. Sessions were one-one with an instructor and held three months apart. Performance was assessed by measuring the time-to-critical actions during the second session. Results Of 42 interns, 22 were in the intervention group and 20 in the control group. There was no statistical difference in time-to-critical actions for VR vs. standard groups; for example, VR times (in seconds) compared to standard times were 18.1 (SD 10.5) and 18.9 (SD 15.8) (p=.90) for oral suction, and 61.6 (SD 24.8) and 62.8 (SD 26.9) (p=.82) for IV lorazepam completion. Conclusion This pilot trial suggests that VR is feasible for clinical simulation. We did not find a significant difference between the two groups in learner performance. Larger studies are needed to corroborate our findings, investigate the best applications of VR in clinical training, and determine if it could lead to more rapid learning at a lower cost.

Facial Artery Pseudoaneurysm in a Child Diagnosed With Point of Care Ultrasound.

This case describes a 3-year-old boy who was brought to the pediatric emergency department for evaluation of facial swelling. The patient's history was remarkable for a deep facial laceration 5 days prior that required surgical repair in the operating room. On the day of presentation, he was noted to have mild swelling and tenderness to palpation of the left jaw below the mandible, in the same location as his recent laceration repair. Point-of-care ultrasound (POCUS) revealed a pseudoaneurysm with an arterial feeding vessel. This was confirmed by radiology-performed ultrasound, and the patient underwent a coil embolization procedure. To our knowledge, this is the first reported case of a pseudoaneurysm being diagnosed by POCUS in a pediatric patient. This case demonstrates the utility of POCUS in facilitating the timely recognition of vascular mass lesions and guiding management in the emergency department to avoid complications.

Acute Hematogenous Osteomyelitis in a Five-Month-Old Male with Rickets.

Osteomyelitis is defined as an infection of the bone, bone marrow, and the surrounding soft tissues. Most cases of acute hematogenous osteomyelitis in children are caused by Gram-positive bacteria, principally Staphylococcus aureus. We present a case where a 5-month-old male had an acute onset of decreased movement of his left leg and increased irritability and was subsequently diagnosed with rickets and hematogenous osteomyelitis with bacteremia. The case explores a possible association between hematogenous osteomyelitis and rickets.

World incidence of AKI: a meta-analysis.

BACKGROUND AND OBJECTIVES: The burden of AKI around the globe has not been systematically examined. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: A systematic review (2004-2012) of large cohort studies was conducted to estimate the world incidence of AKI and its stages of severity and associated mortality, and to describe geographic variations according to countries, regions, and their economies. AKI definitions were reclassified according to the Kidney Disease Improving Global Outcomes (KDIGO) staging system. Random-effects model meta-analyses and meta-regressions were used to generate summary estimates and explore sources of heterogeneity. RESULTS: There were 312 studies identified (n=49,147,878) , primarily in hospital settings. Most studies originated from North America, Northern Europe, and Eastern Asia, from high-income countries, and from nations that spent ≥5% of the gross domestic product on total health expenditure. Among the 154 studies (n=3,585,911) that adopted a KDIGO-equivalent AKI definition, the pooled incidence rates of AKI were 21.6% in adults (95% confidence interval [95% CI], 19.3 to 24.1) and 33.7% in children (95% CI, 26.9 to 41.3). The pooled AKI-associated mortality rates were 23.9% in adults (95% CI, 22.1 to 25.7) and 13.8% in children (95% CI, 8.8 to 21.0). The AKI-associated mortality rate declined over time, and was inversely related to income of countries and percentage of gross domestic product spent on total health expenditure. CONCLUSIONS: Using the KDIGO definition, 1 in 5 adults and 1 in 3 children worldwide experience AKI during a hospital episode of care. This analysis provides a platform to raise awareness of AKI with the public, government officials, and health care professionals.
