The clinical pattern of intentional injuries at a primary Saudi Arabian trauma center.

Purpose: The term "intentional injuries" refers to a spectrum of injuries resulting from self-inflicted injuries, interpersonal violence, and group acts of violence. Intentional injuries are underreported in Saudi Arabia. This study aimed to analyze and evaluate the characteristics of intentional injuries in patients who presented to the emergency department of a primary trauma center in Medina, Saudi Arabia in 2013.

The role of preoperative graded compression ultrasound in detecting acute appendicitis and influencing the negative appendectomy rate.

Purpose: The diagnosis of acute appendicitis is mainly clinical and is correct in about 80% of patients, but 20-33% present with atypical findings, which resulted in a negative appendectomy rate of 20-30%. The graded compression ultrasound method in the diagnosis of acute appendicitis was reported with a sensitivity of 89%, and specificity of 95%. In this study, we aim to evaluate the graded compression ultrasonography in the diagnosis of acute appendicitis, its influence on the clinical judgment to operate, and its role in lowering the negative appendectomy rate.
