Third-year medical students' perceptions of confidence and readiness to perform EFAST after training.

Background: As Point-of-Care Ultrasound (POCUS) education is increasingly incorporated in undergraduate medical education (UME), evaluation of the effectiveness of various ultrasound-related curricula is a developing field. The Extended Focused Assessment with Sonography (EFAST) is a POCUS exam widely used in emergency medicine. This project examines third-year osteopathic medical (OMS III) students' perceptions of the impact of a focused introduction to EFAST training curriculum on their performance ability and utilization of EFAST during third-year clinical rotations.

Tissue Plasminogen Activator (tPA) Use in Persistent Loculated Ascites.

Spontaneous bacterial peritonitis (SBP) complicated by loculated ascites presents a therapeutic challenge, particularly when standard of care or surgical intervention is not feasible. This case report documents the successful use of intraperitoneal tissue plasminogen activator (tPA) as adjunctive salvage therapy in an adult female with decompensated liver cirrhosis and loculated infected ascites. After no improvement in the patient's clinical condition following 14 days of intravenous antibiotics, catheter-directed intraperitoneal tPA was administered for three days, resulting in the improvement of her abdominal pain and resolution of the loculations.
