D-dimer as a Rule-Out for Aortic Dissection.

Introduction Acute aortic dissection (AAD) represents a significant diagnostic challenge with a high mortality rate if not treated promptly. This challenge arises from the diverse clinical presentations of AAD, and its symptom overlap with other medical conditions. Although both helical CT and transesophageal echocardiography are reliable diagnostic tools for AAD, they are not feasible for every suspected case.

Safe driving recommendations following lower extremity orthopedic surgery: a systematic review.

Purpose: We analyzed the published literature on return-to-driving (RTD) recommendations following lower extremity orthopedic surgery, including knee and hip arthroplasty and ankle and foot surgery.

Methods: We conducted a PubMed MEDLINE database search for the relevant literature spanning from 1988 to 2022. Data were extracted from the selected articles independently by six investigators, and the mean, standard deviation, and range of RTD recommendations for each surgical region and procedure were calculated.
