Journal of pediatric gastroenterology and nutrition, Volume 43, Issue 2, 1 1 2006, Pages 265-266 Rhamnose and rhamnitol in dual sugar permeability tests. Malagon I, Onkenhout W, Klok M, van der Poel PF, Bovill JG, Hazekamp MG

Rhamnose is one of the sugars regularly used to conduct the dual sugar permeability test. For more than 30 years, it has been assumed that rhamnose is an inert sugar not metabolized by the human body and only fermented by some colonic bacteria into rhamnulose. While conducting an investigation on gut permeability in children undergoing cardiac surgery, increased concentrations of rhamnitol were found in the urine samples. The present report suggests that rhamnose is not an inert sugar and it is... Abstract

Slart RH, Agool A, van Veldhuisen DJ, Dierckx RA, Bax JJ

Unlabelled: SPECT with 99mTc-labeled agents is better able to detect viability after nitrate administration. Nitrates induce vasodilation and may increase blood flow to severely hypoperfused but viable myocardium, thereby enhancing tracer delivery and improving the detection of viability. Quantitative data on the changes in blood flow are lacking in SPECT but can be provided by PET. The aim of the present study was to use PET to evaluate whether nitrate administration increases blood flow to chr... Abstract

Journal of cardiovascular electrophysiology, Volume 17, Issue 8, 1 1 2006, Pages 899-901 Postero-lateral scar tissue resulting in non-response to cardiac resynchronization therapy. Bleeker GB, Schalij MJ, Van Der Wall EE, Bax JJ

In large cardiac resynchronization therapy (CRT) trials, approximately 20-30% of patients did not respond to CRT. Recent studies indicated that left ventricular (LV) dyssynchrony is needed for response to CRT. However, the presence of LV dyssynchrony may not be the only determinant of response, because some patients with LV dyssynchrony do not benefit from CRT. In the current case report, we present a patient with ischemic cardiomyopathy, NYHA class III heart failure symptoms, and substantial LV... Abstract
