Objective: We sought to assess whether the presence and extent of lung ultrasound (LUS) findings were associated with asthma exacerbation severity in children.

Methods: We enrolled a convenience sample of patients aged 5-18 years presenting with acute asthma exacerbation to a tertiary care pediatric emergency department. Severity of an asthma exacerbation (mild, moderate, severe) was assessed within 1 hour of the LUS using the Hospital Asthma Severity Score, a validated asthma assessment tool.

Objective: The aim of the study is to assess diagnostic performance of cardiac point-of-care ultrasound (POCUS) performed by pediatric emergency medicine (PEM) physicians in children with preexisting cardiac disease.

Methods: We evaluated the use of cardiac POCUS performed by PEM physicians among a convenience sample of children with preexisting cardiac disease presenting to a tertiary care pediatric ED. We assessed patient characteristics and the indication for POCUS.

Pediatric cardiac arrest presents an infrequent but high-stakes event for emergency clinicians, who need to maintain expertise in this area. Evidence regarding pediatric resuscitations has been accumulating substantially over the past decade and highlights the unique considerations and challenges when resuscitating children. This issue reviews resuscitation principles of children in cardiac arrest while addressing the newest evidence-based and best-practice recommendations by the American Heart Association.

Background & Aims: Lean body mass loss due to critical illness in childhood could be detrimental to long term outcomes, including functional status and quality of life. We describe the feasibility of body composition assessment by bioimpedance spectroscopy (BIS) in the pediatric intensive care unit (PICU), and functional status and quality of life assessments up to 6 months following admission in a cohort of mechanically ventilated, critically ill children.

Methods: We conducted a prospective, observational pilot study in a multidisciplinary PICU.

Aim: Orthotopic models utilizing orthotopic implantation have been used for developing cancer models of multiple tumor entities. The aim of this study was to evaluate the role of orthotopic injection in establishing a model of esophageal cancer using a human green fluorescent protein (GFP) cell line of human esophageal carcinoma.

Materials And Methods: Nude mice were orthotopically injected in the abdominal esophagus with stably transfected GFP-PT1590 cells.
