Endotracheal intubation: ultrasound-guided versus fiberscope in patients with cervical spine immobilization.

Background: Ultrasound has growing applications in airway management during anesthesia. The aim of the present study was to evaluate the feasibility of real-time ultrasound-guided tracheal intubation in patients with cervical spine immobilization relative to fiberscope-guided tracheal intubation.

Patients And Methods: This randomized controlled study was carried out on 266 adult patients who have a rigid neck collar in place for cervical spine immobilization and were randomly allocated into two equal groups.

Detection of MicroRNA in Hepatic Cirrhosis and Hepatocellular Carcinoma in Hepatitis C Genotype-4 in Egyptian Patients.

Background: In Egypt, the prevalence of chronic hepatitis C (CHC) infection is 13.8% of whole population and about 80% of the patients with hepatocellular carcinoma have underling hepatitis C.

Aim: This study was designed to assess the diagnostic value of plasma miR-122 and miR-21 in patients with CHC, genotype-4, to detect fibrosis progression versus noninvasive indices and their diagnostic value in detection of early stages of hepatocellular carcinoma (HCC).
