Effects on renal haemodynamics and tubular function of the contrast medium Ioxaglate in renal transplant patients.

The aim of this study was to evaluate the effects of Ioxaglate on renal haemodynamics and tubular function in renal transplant patients at increased risk of nephrotoxicity. 21 patients undergoing either intravenous pyelography or arteriography with Ioxaglate were studied. Renal clearance studies were carried out 1 day before and 1 day after administration of Ioxaglate (173 +/- 37 ml) injected into each patient.

Rectal malacoplakia in renal transplantation: MR features.

This report describes the CT and MRI features of rectal malacoplakia in a renal transplant recipient. The lesion appeared strongly hyperdense (105 HU) on unenhanced CT and demonstrated hypointense signal on T1- and T2-weighted MR imaging with slight homogeneous enhancement after gadolinium injection. These characteristics distinguish this lesion from other more common neoplastic, inflammatory rectal lesions that are typically isointense on T1-weighted imaging and enhance variably after gadolinium injection.

[Comparative evaluation of 2 fiber optic catheters for the continuous measurement of Svo2].

Nineteen intensive care patients with shock and acute respiratory failure were studied using two different fiber-optic catheters used for the continuous measurement of mixed venous blood oxygen saturation (SVO2). In groupe I patients (n = 11), a Swan-Ganz catheter with optic fibres emitting light characterized by three different wavelengths was used (Opticath Oximetrix). In groupe II patients (n = 8), a Sat-one Edwards catheter was used instead (only two different wavelengths).
