Highlights ■ Biomarkers of brain injury, such as neuron-specific enolase and Tau proteins, are higher in older patients with sepsis and delirium. ■ Diagnosing sepsis in patients with delirium can be challenging. ■ Early identification of sepsis is key to managing sepsisassociated delirium. ABSTRACT Objective: Sepsis-associated delirium is a common cerebral manifestation in patients with sepsis, potentially caused by a combination of neuroinflammation and other neurophysiological disorders. This study investigated the expression of neuron-specific enolase and Tau protein as biomarkers […]

Highlights ■ Imaging plays a fundamental role in the diagnosis of acute appendicitis. ■ The study highlights ultrasound’s effectiveness in diagnosing appendicitis. ■ APPENDIC-RADS efficiently standardizes the ultrasound evaluation of appendicitis. ■ Using APPENDIC-RADS may enhance communication and optimize medical practices. ABSTRACT Objective: Abdominal ultrasonography is widely used to evaluate suspected cases of appendicitis. Objective descriptions of the direct and indirect signs of appendicitis result in varied assessments of its likelihood. This study introduces the Appendix Imaging Reporting and Data […]

ABSTRACT Chest pain is a frequent, potentially life-threatening condition in the emergency department and requires immediate investigation and treatment. This case report highlights a rare differential diagnosis of pleuritic chest pain: epipericardial fat necrosis. A 29-year-old man presented with normal clinical evaluation, electrocardiography, point-of-care ultrasound, and unremarkable laboratory tests. The initial hypothesis was acute pleuritis. Chest radiography revealed peri-cardiac nonspecific findings, and computed tomography revealed epicardial fat necrosis. Despite the rarity of this condition, accurate diagnosis allows for better practices. […]
