Introduction and objective: Several studies have shown that rigid fluorescence cystoscopy (RFC) with hexaminolevulinate (HAL) is superior to standard rigid white light (RWLC) cystoscopy in diagnosing bladder tumours, with a clinically relevant impact on the patient's management. These studies, however, have been done with rigid cystoscopes. We carried out a study to evaluate whether the technique of fluorescence cystoscopy with HAL was also feasible with a specially designed flexible fluore... Abstract

Journal of cardiovascular magnetic resonance : official journal of the Society for Cardiovascular Magnetic Resonance, Volume 7, Issue 2, 1 1 2005, Pages 383-389 Disparity between dobutamine stress and physical exercise magnetic resonance imaging in patients with an intra-atrial correction for transposition of the great arteries. Oosterhof T, Tulevski II, Roest AA, Steendijk P, Vliegen HW, van der Wall EE, de Roos A, Tijssen JG, Mulder BJ
Background: In patients with an intra-atrial correction for transposition of the great arteries (TGA) an abnormal response to stress testing is common. However, hemodynamic responses may vary substantially when different stress tests are used. We compared the hemodynamic response to dobutamine stress with the response to physical exercise in patients and controls. Methods: Thirty-nine patients and 25 age/sex-matched control subjects underwent either dobutamine stress (15 microg/kg/min) or submax... Abstract

European journal of echocardiography : the journal of the Working Group on Echocardiography of the European Society of Cardiology, Volume 6, Issue 4, 20 3 2004, Pages 297-300 Underestimation of severity of mitral regurgitation with varying hemodynamics. Scholte AJ, Holman ER, Haverkamp MC, Poldermans D, van der Wall EE, Dion RA, Bax JJ
Transesophageal echocardiography (TEE) is a valuable technique to assess mitral valve anatomy and the mechanism of mitral regurgitation (MR). We present the case of a 35-year-old woman with severe MR due to restrictive motion of the posterior mitral leaflet, who was referred for mitral annuloplasty. Under physiologic circumstances, a severe (grade 3+) MR was present, whereas in the operating room during general anesthesia, the MR had disappeared almost completely. The downgrading of MR due to ge... Abstract

European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery, Volume 27, Issue 3, 19 3 2004, Pages 462-6; discussion 467 Accurate quantitation of regurgitant volume with MRI in patients selected for mitral valve repair. Westenberg JJ, Doornbos J, Versteegh MI, Bax JJ, van der Geest RJ, de Roos A, Dion RA, Reiber JH
Objective: Echocardiography, the currently preferred diagnostic approach for mitral valve regurgitation, cannot accurately quantify the amount of regurgitation. Flow quantification with MRI is possible, but the conventional method (1-directional velocity-encoding) acquires the flow at a fixed location during the cardiac cycle, which is not necessarily the location of the mitral valve during the whole cycle. In this study, the exact flow through the mitral valve was quantified with a 3-directiona... Abstract

Hypertension (Dallas, Tex. : 1979), Volume 45, Issue 2, 13 2 2004, Pages 227-232 Noninvasive evaluation of the coronary arteries with multislice computed tomography in hypertensive patients. Schuijf JD, Bax JJ, Jukema JW, Lamb HJ, Vliegen HW, van der Wall EE, de Roos A
Because patients with hypertension are at increased risk for coronary artery disease, early and noninvasive identification of the disease in patients with hypertension is important. Recently, multislice computed tomography (MSCT) has been demonstrated to allow both noninvasive coronary angiography and assessment of left ventricular function. The purpose of the present study therefore was to demonstrate the feasibility of this approach in patients with hypertension with known or suspected coronar... Abstract

The American journal of cardiology, Volume 94, Issue 12, 1 1 2004, Pages 1506-1509 Comparison of response to cardiac resynchronization therapy in patients with sinus rhythm versus chronic atrial fibrillation. Molhoek SG, Bax JJ, Bleeker GB, Boersma E, van Erven L, Steendijk P, van der Wall EE, Schalij MJ
Cardiac resynchronization therapy (CRT) is a new therapeutic option for patients who have drug-refractory end-stage heart failure. Much information has been obtained from patients who have sinus rhythm, but the use of CRT in patients who have chronic atrial fibrillation (AF) has not been studied extensively. Accordingly, we evaluated the clinical response and long-term survival rate of CRT in patients who had heart failure and chronic AF, and the results were compared with those in patients who...

Biochemical pharmacology, Volume 68, Issue 11, 1 1 2004, Pages 2273-2281 A methylester of the glucuronide prodrug DOX-GA3 for improvement of tumor-selective chemotherapy. de Graaf M, Nevalainen TJ, Scheeren HW, Pinedo HM, Haisma HJ, Boven E
The glucuronide prodrug of doxorubicin, DOX-GA3, can be selectively activated in tumors by extracellular human beta-glucuronidase, resulting in a better therapeutic index than doxorubicin. DOX-GA3, however, is rapidly excreted by the kidney. We hypothesized that slow release of DOX-GA3 from its methylester, DOX-mGA3, by esterase activity in blood would result in improved circulation half-life (t(1/2)) of DOX-GA3. DOX-mGA3 was synthesized more efficiently with an overall yield of 60% as compared... Abstract

Background: There is evidence that surfactant protein (SP)-D is important in the innate, as well as in the adaptive pulmonary immune response. Serum concentrations of SP-D have been proposed as parameter of the integrity of the blood-airspace barrier in interstitial lung diseases. We hypothesized that serum SP-D concentrations are affected in allergic patients and correlate with changes in allergic airway inflammation. Objective: To determine levels of serum SP-D in allergic patients compared wi... Abstract
