Emergency Facial Injuries in Athletics.

Dental and oral injuries are a common occurrence in sport. Initial evaluation should always begin with an assessment of the patient's airway, breathing, circulation, as well as identification of associated injuries. Tooth avulsions are the only true dental emergency.

Prevalence of Positive Rapid Antigen Tests After 7-Day Isolation Following SARS-CoV-2 Infection in College Athletes During Omicron Variant Predominance.

Importance: The US Centers for Disease Control and Prevention shortened the recommended isolation period for SARS-CoV-2 infection from 10 days to 5 days in December 2021. It is unknown whether an individual with the infection may still have a positive result to a rapid antigen test and potentially be contagious at the end of this shortened isolation period.

Objective: To estimate the proportion of individuals with SARS-CoV-2 infection whose rapid antigen test is still positive starting 7 days postdiagnosis.

Accuracy of Rapid Antigen vs Reverse Transcriptase-Polymerase Chain Reaction Testing for SARS-CoV-2 Infection in College Athletes During Prevalence of the Omicron Variant.

This case series evaluates the performance of rapid antigen tests in detecting SARS-CoV-2 infection in college athletes during prevalence of a dominant Omicron variant.

Fentanyl-contaminated cocaine outbreak with laboratory confirmation in New York City in 2019.

Background: Illicitly manufactured fentanyl and fentanyl analogues (IMFs) are being increasingly suspected in overdose deaths. However, few prior outbreaks have been reported thus far of patients with laboratory-confirmed IMF toxicity after reporting intent to use only nonopioid substances. Herein we report a case series of nine patients without opioid use disorder who presented to two urban emergency departments (EDs) with opioid toxicity after insufflating a substance they believed to be cocaine.

Point-of-Care Ultrasound Used to Distinguish Between Superficial Skin Abscess and Deep Mediastinal Abscess: A Case Report.

Background: Skin and soft tissue infections (SSTIs) are an increasingly common complaint in the emergency department (ED), but physical examination does not reliably identify abscesses or accurately determine which skin lesions require incision and drainage. Point-of-care ultrasound (POCUS) improves management of soft tissue skin infections by detecting occult abscess, preventing unnecessary procedures, and identifying more complex disease requiring further imaging.

Case Report: Here, we report a case in which POCUS drastically changed the management of what initially appeared to be an uncomplicated superficial skin abscess but was actually a much more serious mediastinal infection.

Impact of knee modeling approach on indicators and classification of anterior cruciate ligament injury risk.

Introduction: The aim of this study was to determine whether using a direct kinematic (DK) or inverse kinematic (IK) modeling approach could influence the estimation of knee joint kinematics, kinetics, and ACL injury risk classification during unanticipated side cutting.

Methods: The three-dimensional motion and force data of 34 amateur Australian rules footballers conducting unanticipated side-cutting maneuvers were collected. The model used during the DK modeling approach was an eight-segment lower body model with the hip, knee, and ankle free to move in six degrees of freedom.
