Comparative analysis of carrier-based obturation and lateral compaction: a retrospective clinical outcomes study.

The purpose of this retrospective study was to compare the outcome of primary endodontic treatment using a standardized cleaning and shaping technique and obturation with either lateral compaction or carrier-based obturation. Patients received primary endodontic treatment in the predoctoral dental clinic using a standardized cleaning and shaping protocol. All root canals were obturated using AH Plus(TM) sealer with lateral compaction of gutta-percha (LC) or carrier-based obturation (CBO).

Clostridium difficile-associated disease in allogeneic hematopoietic stem-cell transplant recipients: risk associations, protective associations, and outcomes.

The purpose of this study was to evaluate risk factors, protective factors, and outcomes associated with Clostridium difficile-associated disease (CDAD) in allogeneic hematopoietic stem-cell transplant (HSCT) recipients. A case-control study was performed with 37 CDAD cases and 67 controls. In the multivariable logistic regression analysis, receipt of a third or fourth generation cephalosporin was associated with increased risk of CDAD (OR = 4.

Severity of Clostridium difficile-associated disease (CDAD) in allogeneic stem cell transplant recipients: evaluation of a CDAD severity grading system.

The purpose of this study was to develop and test a Clostridium difficile-associated disease (CDAD) grading system based on presenting symptoms in allogeneic stem cell transplant recipients. Patients with severe CDAD had significantly shorter median survival times and more adverse outcomes than patients with mild or moderate CDAD.
