Objectives: To evaluate the proficiency of a HIPAA-compliant version of GPT-4 in identifying actionable, incidental findings from unstructured radiology reports of Emergency Department patients. To assess appropriateness of artificial intelligence (AI)-generated, patient-facing summaries of these findings.

Materials And Methods: Radiology reports extracted from the electronic health record of a large academic medical center were manually reviewed to identify non-emergent, incidental findings with high likelihood of requiring follow-up, further sub-stratified as "definitely actionable" (DA) or "possibly actionable-clinical correlation" (PA-CC).

Background: Review of emergency department (ED) revisits with admission allows the identification of improvement opportunities. Applying a health equity lens to revisits may highlight potential disparities in care transitions. Universal definitions or practicable frameworks for these assessments are lacking.

The recent emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has posed formidable challenges for clinical laboratories seeking reliable laboratory diagnostic confirmation. The swift advance of the crisis in the United States has led to Emergency Use Authorization (EUA) facilitating the availability of molecular diagnostic assays without the more rigorous examination to which tests are normally subjected prior to FDA approval. Our laboratory currently uses two real-time reverse transcription-PCR (RT-PCR) platforms, the Roche Cobas SARS-CoV2 and the Cepheid Xpert Xpress SARS-CoV-2.

Article Synopsis
  • Oral squamous cell carcinomas (OSCCs) often present late and have a poor prognosis, partly due to inadequate understanding of genetic changes related to tumor development.
  • * The study aimed to identify copy number alterations (CNAs) in OSCC using advanced genetic techniques and explore how these alterations correlate with clinical characteristics and outcomes.
  • * Findings revealed several key chromosomal regions with frequent amplifications and deletions associated with tumor size and staging, suggesting that specific genetic patterns could serve as independent prognostic factors for OSCC.*

Although the clinical presentations of deep venous thrombosis are notoriously subtle and nonspecific, risk stratification tools such as the Wells clinical model have improved the efficiency of the diagnostic evaluation. The emergency clinician may be guided down several pathways, including D-dimer assays and/ or ultrasonography. New oral anticoagulants offer alternatives to the traditional heparins and vitamin K antagonists in the treatment of deep venous thrombosis.

Background: Thoracic aortic dissection (TAD) and aneurysm (TAA) are rare but catastrophic. Prompt recognition of TAD/TAA and differentiation from acute coronary syndrome (ACS) is difficult yet crucial. Earlier identification of TAA/TAD based upon routine emergency department screening is necessary.

Background: Evisceration of bowel contents through the vagina is a rare event that may be complicated by bowel obstruction.

Objective: We report a case of vaginal evisceration with small bowel obstruction which, in contrast to previous, more dramatic case reports in the literature, is a more subtle and, in fact, characteristic clinical presentation for this unusual occurrence.

Case Report: A 72-year-old woman with a previous history of pelvic surgery presented to the Emergency Department with lower abdominal discomfort and a prolapsing mass from her vagina.

Chest pain is one of the most frequently seen chief complaints in patients presenting to emergency departments, and is considered to be a "high-risk" chief complaint. The differential diagnosis for chest pain is broad, and potential causes range from the benign to the immediately life-threatening. Although many (if not most) emergency department patients with chest pain do not have an immediately life-threatening condition, correct diagnoses can be difficult to make, incorrect diagnoses may lead to catastrophic therapies, and failure to make a timely diagnosis may contribute to significant morbidity and mortality.
