Critical Care of the Pediatric Burn Patient.

Life-saving pediatric burn care is often initiated in hospitals that are not designated as a pediatric burn center. Therefore, familiarity with critical care of pediatric burn patients is crucial for physicians working in all healthcare settings equipped to care for children. Management of airway, mechanical ventilation, preservation of ideal circulatory status, and establishment of vascular access in pediatric burn patients requires many unique considerations.

Revisiting dexamethasone use in the pediatric emergency department.

Purpose Of Review: Dexamethasone is an essential treatment for common pediatric inflammatory, airway, and respiratory conditions. We aim to provide up-to-date recommendations for treatment of anaphylaxis, croup, coronavirus disease, multisystem inflammatory syndrome in children, and asthma with dexamethasone for use in the pediatric emergency department.

Recent Findings: Literature largely continues to support the use of dexamethasone in most of the above conditions, however, recommendations for dosing and duration are evolving.

POCUS in the PICU: A Narrative Review of Evidence-Based Bedside Ultrasound Techniques Ready for Prime-Time in Pediatric Critical Care.

Point-of-care ultrasound (POCUS) is an accessible technology that can identify and treat life-threatening pathology in real time without exposing children to ionizing radiation. We aim to review current evidence supporting the use of POCUS by pediatric intensivists with novice-level experience with bedside ultrasound. Current evidence supports the universal adoption of POCUS-guided internal jugular venous catheter placement and arterial line placement by pediatric critical care physicians.

Operational Innovation in the Provision of Pediatric Extracorporeal Membrane Oxygenation for Multisystem Inflammatory Syndrome in Children.

Treatment of multisystem inflammatory syndrome in children (MIS-C) can require significant critical care resources. Our aim is to alert mixed pediatric and adult hospitals worldwide of the possibility that pediatric and adult patients may simultaneously require cannulation to extracorporeal membrane oxygenation (ECMO) for MIS-C and severe COVID-19. We conducted a retrospective review of operations required to treat cardiogenic shock in 3 pediatric patients with a diagnosis of MIS-C admitted to a single medium-sized pediatric referral center located within a large academic medical center over a 14-day period.

Adult COVID-19 Patients Cared for in a Pediatric ICU Embedded in a Regional Biothreat Center: Disease Severity and Outcomes.

The objective of this study was to describe the clinical characteristics and outcomes of adult coronavirus disease 2019 (COVID-19) patients admitted to a pediatric intensive care unit (PICU), with assessment of respiratory clinical severity and outcomes when cared for by pediatric intensivists utilizing specific care processes. We conducted a retrospective cohort study of adult patients admitted to the 14-bed PICU of a quaternary referral center during the COVID-19 surge in Boston between April and June 2020. A total of 37 adults were admitted: 28 tested COVID-19 positive and 9 tested COVID-19 negative.

Respiratory Failure Leading to Intubation in the Setting of Flibanserin Ingestion in a Toddler.

The Psychiatric Consultation Service at Massachusetts General Hospital sees medical and surgical inpatients with comorbid psychiatric symptoms and conditions. During their twice-weekly rounds, Dr Stern and other members of the Consultation Service discuss diagnosis and management of hospitalized patients with complex medical or surgical problems who also demonstrate psychiatric symptoms or conditions. These discussions have given rise to rounds reports that will prove useful for clinicians practicing at the interface of medicine and psychiatry.

Pax6- and Six3-mediated induction of lens cell fate in mouse and human ES cells.

Embryonic stem (ES) cells provide a potentially useful in vitro model for the study of in vivo tissue differentiation. We used mouse and human ES cells to investigate whether the lens regulatory genes Pax6 and Six3 could induce lens cell fate in vitro. To help assess the onset of lens differentiation, we derived a new mES cell line (Pax6-GFP mES) that expresses a GFP reporter under the control of the Pax6 P0 promoter and lens ectoderm enhancer.

Amniocytes can serve a dual function as a source of iPS cells and feeder layers.

Clinical barriers to stem-cell therapy include the need for efficient derivation of histocompatible stem cells and the zoonotic risk inherent to human stem-cell xenoculture on mouse feeder cells. We describe a system for efficiently deriving induced pluripotent stem (iPS) cells from human and mouse amniocytes, and for maintaining the pluripotency of these iPS cells on mitotically inactivated feeder layers prepared from the same amniocytes. Both cellular components of this system are thus autologous to a single donor.
