Clinical significance of elevated D-dimer in emergency department patients: a retrospective single-center analysis.

Introduction: D-dimer is a marker of coagulation and fibrinolysis widely used in clinical practice for assessing thrombotic activity. While it is commonly ordered in the Emergency Department (ED) for suspected venous thromboembolism (VTE), elevated D-dimer levels can occur due to various other disorders. The aim of this study was to find out the causes of elevated D-dimer in patients presenting to a large ED in Saudi Arabia and evaluate the accuracy of D-dimer in diagnosing these conditions.

Emergency medicine in Saudi Arabia: a century of progress and a bright vision for the future.

Although emergency medical services (EMS) and pre-hospital care have existed in the Kingdom of Saudi Arabia (KSA) since 1934, emergency medicine (EM) is a relatively new medical field in the country that was not formally recognized as a medical specialty until 2001. In 2005, the Saudi Board of Emergency Medicine formed to develop, implement, and evaluate a standardized curriculum for EM residents. Since then, EM and the pre-hospital system in the KSA has evolved and grown.

Intravenous Versus Nonintravenous Benzodiazepines for the Cessation of Seizures: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Background: The acquisition of intravenous (IV) access in the actively convulsing patient is difficult. This often delays the administration of the IV benzodiazepine (BDZ) necessary for seizure cessation. Delays in seizure cessation are associated with increased pharmacoresistance, increased risk of neuronal injury, worse patient outcomes, and increased morbidity.

Systematic review and meta-analysis for the use of ultrasound versus radiology in diagnosing of pneumonia.

Background: Physicians are increasingly using point of care lung ultrasound (LUS) for diagnosing pneumonia, especially in critical situations as it represents relatively easy and immediately available tool. They also used it in many associated pathological conditions such as consolidation, pleural effusion, and interstitial syndrome with some reports of more accuracy than chest X-ray. This systematic review and meta-analysis are aimed to estimate the pooled diagnostic accuracy of ultrasound for the diagnosis of pneumonia versus the standard chest radiological imaging.
