Lower Endoscopic Diagnostic Yields Observed in Non-hematemesis Gastrointestinal Bleeding Patients.

Background: Location of bleeding can present a diagnostic challenge in patients without hematemesis more so than those with hematemesis.

Aim: To describe endoscopic diagnostic yields in both hematemesis and non-hematemesis gastrointestinal bleeding patient populations.

Methods: A retrospective analysis on a cohort of 343 consecutively identified gastrointestinal bleeding patients admitted to a tertiary care center emergency department with hematemesis and non-hematemesis over a 12-month period.

A Prospective, Multicenter Study of the AIMS65 Score Compared With the Glasgow-Blatchford Score in Predicting Upper Gastrointestinal Hemorrhage Outcomes.

Background: The AIMS65 score and the Glasgow-Blatchford risk score (GBRS) are validated preendoscopic risk scores for upper gastrointestinal hemorrhage (UGIH).

Goals: To compare the 2 scores' performance in predicting important outcomes in UGIH.

Study: A prospective cohort study in 2 tertiary referral centers and 1 community teaching hospital.

The AIMS65 score compared with the Glasgow-Blatchford score in predicting outcomes in upper GI bleeding.

Introduction: We previously derived and validated the AIMS65 score, a mortality prognostic scale for upper GI bleeding (UGIB).

Objective: To validate the AIMS65 score in a different patient population and compare it with the Glasgow-Blatchford risk score (GBRS).

Design: Retrospective cohort study.

Further evidence of the association between periodontal conditions and coronary artery disease.

Background: There is increasing evidence that chronic infections, such as periodontal diseases, could play a role in the initiation and development of coronary artery disease (CAD). The present study was intended to test for a possible association between presence and severity of periodontitis and coronary artery disease in a Belgian population.

Methods: A total of 108 CAD patients (mean age 59.

Experimental comparison of cavity sealing ability of five dental adhesive systems after thermocycling.

Purpose: To evaluate the cavity sealing obtained after thermocycling with five adhesive systems in which one all-in-one adhesive was compared to three one-bottle adhesives, and to observe the effect of a low-charged resin layer added to a one-bottle adhesive.

Materials And Methods: Twenty-five recently extracted teeth were randomly allocated to five experimental adhesive systems (n = 5 each): Optibond Solo (OS), Scotchbond 1 (SB1), PQ 1, Prompt-L-Pop (PLP), SB1+Revolution (R). On each tooth, two rectangular cavities at the cementoenamel junction were filled with a microhybrid composite (Z100) and the tested adhesives.

Systemic release of endotoxins induced by gentle mastication: association with periodontitis severity.

Background: Periodontitis has recently been identified as a potential risk factor for systemic pathologies such as cardiovascular disease, the hypothesis being that periodontal pockets could release pro-inflammatory bacterial components, for instance endotoxins, into the bloodstream. It is known that the oral cavity can be a source of circulating bacteria, but this has never been shown for bacterial endotoxins, and no evidence exists so far that the risk of systemic injury is related to the severity of periodontitis. The aim of the present study was to test the influence of gentle mastication on the occurrence of endotoxemia in patients with or without periodontal disease.
