statement of problem: various factors are involved in causing inflammation following root canal treatment. controlling these factors may relieve the related pain. one of these factors is extrusion of debris beyond the apex. although debris extrusion happens in all instrumentation techniques, researchers have declared that in coronal flaring technique, there is minimum debris extrusion. purpose:...

Background and Objectives: The pain and anxiety experienced by burn patients during dressing change cannot be thoroughly controlled by painkillers and anxiolytics. Evidence has documented that reciting the name of God can positively impact the reduction of pain and anxiety caused by aggressive procedures. Therefore, the present study aimed to investigate the effect of reciting the name of God o...

Prevention and treatment of bacterial colonised/infected wounds are critical. Many commercially available silver dressings claim broad-spectrum bactericidal activity over days and are indicated for serious conditions including burns and ulcers. However, there is no peer-reviewed literature available for many newer dressings. This study compared the activity of some of these dressings. Six silve...

BACKGROUND The economic impact of adding chlorhexidine gluconate (CHG)-impregnated sponge dressing to standard care (ie, chg-impregnated sponge dressing + skin preparation and transparent film dressing vs skin preparation and transparent film dressing) for the prevention of central-line infections was evaluated. METHODS Clinical and economic data were obtained from peer-reviewed published stu...

BACKGROUND New transparent dressings with chlorhexidine gluconate in the dressing are available. OBJECTIVES To compare the effectiveness of a new 1-piece occlusive dressing that incorporates chlorhexidine gluconate with that of a dressing plus a chlorhexidine gluconate patch in maintaining the low rate of catheter-related bloodstream infections in the intensive care unit and to evaluate nurse...

BACKGROUND Cutaneous leishmaniasis (CL) is a neglected infectious disease and a major health problem in several developing countries. Despite some reasonable explanation for their potential benefits, there is only trace evidence regarding the role of dressings in the treatment of CL. METHODS This randomized, assessor-blind, controlled, clinical trial was conducted in an endemic area for CL ca...

F1-ATPase (F1) is a reversible ATP-driven rotary motor protein. When its rotary shaft is reversely rotated, F1 produces ATP against the chemical potential of ATP hydrolysis, suggesting that F1 modulates the rate constants and equilibriums of catalytic reaction steps depending on the rotary angle of the shaft. Although the chemomechanical coupling scheme of F1 has been determined, it is unclear ...

BACKGROUND Despite the benefits of continuous peripheral nerve blocks, catheter dislodgment remains a major problem, especially in the ambulatory setting. However, catheter dressing techniques to prevent such dislodgment have not been studied rigorously. We designed this simulation study to test the strength of two commercially available catheter dressings. METHODS Using a cadaver model, we r...

OBJECTIVE To investigate two approaches to treating patients with persistent dressing problems and cognitive difficulties following stroke. DESIGN Pilot randomized controlled trial. SETTING Inpatient stroke rehabilitation service. SUBJECTS Seventy consecutive stroke patients with persistent dressing problems and accompanying cognitive difficulties at two weeks after their stroke. INTERV...

PURPOSE Getting dressed is an activity that is of particular difficulty for many persons with dementia, given the need for hand-eye coordination, fine motor skills, and overall planning skills. Despite several studies concerning interventions to improve dressing behavior, very little is known about the dressing process as it is currently performed. The purpose of this study is to characterize t...
