Background: Immunoglobulin A vasculitis, historically known as Henoch-Schönlein purpura, is a rare form of autoimmune-induced vasculitis most common in children. This disease is characterized by a purpuric rash, arthritis, digestive tract complication, and renal inflammation (Hopkins).

Case Report: We present the case of a 78-year-old man in the emergency department with findings of weakness, abdominal pain, and bloody diarrhea for 3 days and a new-onset bilateral lower extremity rash.

Use of Hotels as a Disposition Alternative to Hospital Admission for Undomiciled Patients Undergoing SARS-CoV-2 Testing.

Introduction: The coronavirus 2019 (COVID-19) pandemic has presented various unprecedented challenges to healthcare systems globally, prompting society to adopt new preventative strategies to curb spread of the disease. Those experiencing homelessness have been particularly impacted because of barriers to practicing social distancing, inability to isolate, and poor access to care. Project Roomkey was established in California as a statewide measure to provide non-congregate shelter options for individuals experiencing homelessness to properly quarantine.

Geriatric Falls: Patient Characteristics Associated with Emergency Department Revisits.

Introduction: Falls are the leading cause of traumatic injury among elderly adults in the United States, which represents a significant source of morbidity and leads to exorbitant healthcare costs. The purpose of this study was to characterize elderly fall patients and identify risk factors associated with seven-day emergency department (ED) revisits.

Methods: This was a multicenter, retrospective, longitudinal cohort study using non-public data from 321 licensed, nonfederal, general, and acute care hospitals in California obtained from the Department of Healthcare Access and Information from January 1-December 31, 2017.

Ultrasound-Guided vs. Landmark Method for Subclavian Vein Catheterization in an Academic Emergency Department.

Background: Ultrasound guidance has been shown to decrease complication rates and improve success for internal jugular and femoral vein catheterization in the emergency department (ED). However, the current data on the efficacy and safety of ultrasound-guided subclavian vein catheterization has failed to provide support for similar conclusions.

Objective: To determine if ultrasound-guided subclavian vein catheterization is safer and more efficacious than the traditional landmark method in an ED setting.

Atraumatic Bilateral Renal Subcapsular Urinomas in a Young, Healthy Female.

Background: Urinomas are rare and generally result from trauma to any part of the urinary collecting system. Appropriate imaging is crucial in the timely diagnosis and management of urinomas and for ruling out other etiologies such as subcapsular renal hematomas and perinephric abscesses.

Real-time Point-of-care Ultrasound for the Diagnosis and Treatment of Testicular Torsion.

: Testicular torsion is a surgical emergency that needs prompt diagnosis and treatment. Point-of-Care ultrasound (POCUS) can not only establish the diagnosis but also guide the Emergency Physician in evaluating the response to manual detorsion. : We describe the case of a 13-year-old male who presented with acute scrotal pain.

Diagnosing Achilles Tendon Rupture with Ultrasound in Patients Treated Surgically: A Systematic Review and Meta-Analysis.

Background: Achilles tendon rupture is a common injury with increasing incidence due to the rising popularity of high-velocity sports, continued physical activity of the aging American population, and use of fluoroquinolones and steroid injections. The diagnosis can often be missed or delayed, with up to 20% misdiagnosed, most commonly as an ankle sprain.

Objective: The aim of our study was to systematically evaluate the reported sensitivity, specificity, and likelihood ratios of ultrasound for detecting Achilles tendon rupture in patients who were treated surgically.

Bilateral Retinal Detachments in a Healthy 22-year-old Woman After Moderna SARS-COV-2 Vaccination.

Background: Although uncommon, retinal detachments are medically urgent and can result in permanent vision loss if untreated. Bilateral retinal detachments in healthy individuals are even more rare. In addition, there are no cases to date of retinal detachment associated with either coronavirus disease 2019 (COVID-19) or after receiving the Moderna (mRNA-1273) severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) vaccine.

Choledochal Cyst Mimicking Gallbladder with Stones in a Six-Year-Old with Right-sided Abdominal Pain.

Choledochal cysts are rare but serious bile duct abnormalities are found in young children, usually during the first year of life.1 They require urgent surgical intervention due to the risk of developing cholangiocarcinoma.2 Clinicians should consider this diagnosis and perform a point-of-care ultrasound (POCUS) when a child presents to the emergency department (ED) with findings of jaundice, abdominal pain, and the presence of an abdominal mass.
