A Case Report of Spontaneous Pneumomediastinum From an Unusual Cause: Baritone Practice.

Spontaneous pneumomediastinum (SPM) is a rare but potentially life-threatening clinical entity in which free air is introduced into the mediastinum. It most commonly presents in young males and has an incidence of approximately 0.002% of the general population.

Systemic Lupus Erythematosus in the Elderly That Debuts With an Organic Manifestation of Lupus Nephritis.

Systemic lupus erythematosus (SLE) is a systemic autoimmune condition with many clinical presentations. It is classically seen in young to middle-aged females and can present with cutaneous, renal, serosal, hematological, joint, and/or neurological manifestations at the time of diagnosis or may develop over the course of the disease. Late-onset SLE or SLE in the elderly is a subtype that differs from the classic SLE in age group, clinical presentation, involvement of organs, and severity.

Esophageal Rupture Associated With COVID-19: A Novel Case Report.

Emergency departments (EDs) are the primary driver for hospital admissions in the United States (US), and that trend is likely to continue through the ongoing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. As the US continues to experience rampant community spread, coronavirus disease 2019 (COVID-19) will likely present in increasingly variable ways to the EDs. We present a case of Mallory-Weiss tear and esophageal perforation, which was likely caused by COVID-19 pneumonia.

Novel Use of Home Pulse Oximetry Monitoring in COVID-19 Patients Discharged From the Emergency Department Identifies Need for Hospitalization.

Objectives: Our objective was to evaluate patient-reported oxygen saturation (SpO ) using pulse oximetry as a home monitoring tool for patients with initially nonsevere COVID-19 to identify need for hospitalization.

Methods: Patients were enrolled at the emergency department (ED) and outpatient testing centers. Each patient was given a home pulse oximeter and instructed to record their SpO every 8 hours.
