Monoclonal Antibody Infusions for Outpatient Management of Mild-Moderate COVID-19.

Background: The COVID-19 pandemic has led to a rapid, exponential increase in hospitalizations and morbidity/mortality. In November 2020, the Food and Drug Administration (FDA) issued Emergency Use Authorizations (EUAs) permitting administration of the first monoclonal antibodies (mAb) for outpatient treatment of COVID-19. Early data showed a reduction in COVID-19-related hospitalizations with few adverse events.

Measuring success: A comparison of ultrasound and landmark guidance for knee arthrocentesis in a cadaver model.

Objective: Knee arthrocentesis can be performed by landmark (LM) or ultrasound (US) guidance. The goal of performing knee arthrocentesis is to obtain synovial fluid, however, it is also important to consider the number of attempts required and accidental bone contacts that occur. This study evaluates procedural success without bone contact in knee arthrocentesis and compares both LM and US guided techniques in a cadaver model.

A Case Report of Acute Motor and Sensory Polyneuropathy as the Presenting Symptom of SARS-CoV-2.

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) typically presents with respiratory illness and fever, however some rare neurologic symptoms have been described as presenting complaints. We report a case of an acute motor and sensory polyneuropathy consistent with Miller-Fisher Syndrome (MFS) variant of Guillain Barre Syndrome (GBS) as the initial symptom.

Case Report: A 31-year old Spanish speaking male presents with two months of progressive weakness, numbness, and difficult walking.

Point-of-Care Ultrasound to Assess Gastric Content in Pediatric Emergency Department Procedural Sedation Patients.

Objectives: There is debate regarding the timing of procedural sedation and analgesia (PSA) in relation to fasting status. Point-of-care ultrasound (POCUS) provides the ability to measure gastric content and is being used as a surrogate for aspiration risk in anesthesia. We sought to evaluate the gastric content of pediatric emergency department (PED) patients undergoing PSA using POCUS.

Point-of-Care Ultrasound to Assess Gastric Content.

Gastric ultrasound (US) is a growing modality within the point-of-care ultrasound (POCUS) field. It provides the ability to directly measure an individual patient's gastric content and has potential use as both a clinical and a research tool. Here, we review the historical development of current gastric US models and their clinical application within the field of general anesthesia, describe the US findings and technique for using POCUS to assess gastric content, and discuss the current and potential applications of gastric POCUS within the emergency department.

Ultrasound-Guided Posterior Tibial Nerve Block for Plantar Foot Foreign Body Removal.

Ultrasound-guided regional anesthesia is a growing modality within the pediatric emergency department. Here we present a case where a posterior tibial nerve block was used for anesthesia during foreign body removal from the plantar foot. We further review the technique and literature regarding this straightforward and highly effective procedure.

Point-of-Care Ultrasound for Pediatric Shock.

The evaluation of critically ill children in the emergency department is oftentimes challenging. Point-of-care ultrasound is an essential tool in the rapid identification of reversible pathology and provides unique insight into the appropriate treatment approach. In this article, we discuss a straightforward sonographic approach to pediatric patients who present in shock.

Pulmonary embolism in the pediatric emergency department: a case demonstrating the application of point-of-care cardiac ultrasound in a pediatric patient with pulmonary embolism.

Although pulmonary embolism in children is rare, it is important for the pediatric emergency medicine provider to be aware of its presentation and emergent management. We present a case of bilateral pulmonary embolisms in an adolescent patient to illustrate the benefits from the timely diagnosis of right ventricular dysfunction by point-of-care echocardiography performed by emergency medicine physicians. Ultrasonographic techniques and the emergent management of pulmonary embolism are reviewed.

Ultrasound-guided diagnosis of occult mandibular osteomyelitis.

Background: Skin and soft-tissue infections (SSTIs) are common disease presentations to the emergency department (ED), with the majority of the infections attributed to community-acquired methicillin-resistant Staphylococcus aureus. Rapid and accurate identification of potentially serious SSTIs is critical. Clinician-performed ultrasonography (CPUS) is increasingly common in the ED, and assists in rapid and accurate identification of a variety of disease processes.

Emergency department bedside ultrasound diagnosis of retinoblastoma in a child.

A 30-month-old boy presented to a Haitian emergency department with proptosis, periorbital edema, and progressive blindness. Bedside ultrasound examination revealed bilateral ocular masses with dense calcifications pathognomonic for retinoblastoma. This case illustrates the diagnostic utility of bedside ultrasound for an advanced case of retinoblastoma in a resource-poor setting.

Dermatomyositis with extensive calcification in an adult.

This report reviews a case of dermatomyositis presenting with weakness and extensive calcification in an adult. While dermatomyositis is not uncommon in adults, it is uncommon for calcifications to be present. Children develop calcifications more frequently than adults.
