Comparison of Glasgow-Blatchford score and full Rockall score systems to predict clinical outcomes in patients with upper gastrointestinal bleeding.

Background: Various risk scoring systems have been recently developed to predict clinical outcomes in patients with upper gastrointestinal bleeding (UGIB). The two commonly used scoring systems include full Rockall score (RS) and the Glasgow-Blatchford score (GBS). Bleeding scores were assessed in terms of prediction of clinical outcomes in patients with UGIB.

Diagnostic value of fine-needle aspiration in head and neck lymphoma: a cross-sectional study.

The objective of this paper was that fine-needle aspiration (FNA) has become a well-liked modality in the diagnosis, staging, and follow-up of head and neck masses. Limited studies exist regarding the value of FNA in the diagnosis of head and neck masses. We aimed to evaluate the diagnostic value of head and neck lymphomas.

Decrease in infection rate following use of povidone-iodine during transrectal ultrasound guided biopsy of the prostate: a double blind randomized clinical trial.

Background: Infection after transrectal ultrasound (TRUS) guided biopsy of the prostate is a major and potentially life-threatening problem. Using antibiotic premedication can not completely eliminate infection after biopsy.

Objectives: We performed this study to determine the value of using povidone-iodine in prevention of post biopsy infection.
