UNDERESTIMATION OF PFO SIZE WITH SALINE CONTRAST TECHNIQUE

Evidence for a size underestimation of upright faces.

We quantitatively examined the difference in perceived size between upright and inverted faces using the method of constant stimuli. The stimuli included eight face images modified from two cartoon faces produced by Kitaoka (2007, http://www.psy.ritsumei.ac.jp/-akitaoka/kao-e.html and 2008, Cognitive Psychology 5 177-185) and six photographic faces, including a photographic face used by Thompso...

Presumption of deterioration concrete strength by small size core and X- ray technique with contrast medium

This paper proposes a method of evaluating the strength of concrete below a degraded surface determined from an x-ray image taken of a 10 mm and 30 mm core cut from the insitu concrete. The image was enhanced by impregnation of the surface with a contrast medium. Several types of concrete having different water-cement ratio were used in the experiment. As a result, it is showed that the strengt...

Underestimation of Pupil Size by Critical Care and Neurosurgical Nurses.

BACKGROUND Early detection of pupillary changes in patients with head injuries can alert the care team to increasing intracranial pressure. Previous research has shown inconsistencies in pupil measurement that are most likely due to the subjective nature of measuring pupils without the assistance of technology. OBJECTIVES To evaluate nurses' abilities to assess pupil diameter accurately and d...

A Simple Technique of Giving Intravenous Quinine with Saline

Percutaneous PFO closure with Amplatzer PFO occluder: predictors of residual shunts at 6 months follow-up.

OBJECTIVE The objective of this study was to assess predictors of residual shunts after percutaneous patent foramen ovale (PFO) closure with Amplatzer PFO occluder (AGA Medical Corporation, Golden Valley, MN, USA). METHODS All percutaneous PFO closures, using Amplatzer PFO occluder performed at a tertiary center between May 2002 and August 2006, were reviewed. Follow-up, including saline cont...
