Agreement of multislice CT angiography and MR angiography in assessing the degree of carotid artery stenosis in consideration of different methods of postprocessing.

Objective: We investigated the agreement of multislice computed tomography angiography (CTA) and magnetic resonance angiography (MRA) in the quantitative measurement of carotid artery stenosis. The dependency of the agreement of the chosen postprocessing procedures was also investigated.

Methods: Fifty consecutive symptomatic patients were included in this study.

Diagnosis of hepatic veno-occlusive disease by plasminogen activator inhibitor-1 plasma antigen levels: a prospective analysis in 350 allogeneic hematopoietic stem cell recipients.

Background: Veno-occlusive disease (VOD) is one of the most serious complications following allogeneic hematopoietic stem cell transplantation (HSCT) and is associated with a high mortality. We conducted a large trial in order to investigate the value of plasminogen activator inhibitor-1 (PAI-1) plasma antigen levels in VOD patients as PAI-1 has been described as a possible diagnostic marker of VOD.

Methods: In all, 350 stem cell recipients were included in our study.

Factor XIII activity levels in patients with allogeneic haematopoietic stem cell transplantation and acute graft-versus-host disease of the gut.

Severe graft-versus-host disease (GvHD) of the gut clinically resembles Crohn's disease and ulcerative colitis. As low plasma levels of factor XIII (FXIII) have been described in chronic inflammatory bowel disease (CIBD) and as beneficial effects of FXIII concentrates in CIBD have been reported, we studied the FXIII plasma activity levels in patients undergoing allogeneic stem cell transplantation (SCT). In 20 of 22 patients with an uncomplicated course of SCT, FXIII stayed within the normal range (median 102 iu/dl, range 74-122), but was significantly reduced with the lowest FXIII levels on d 0 and 7 (d 0: median 83 iu/dl, range 55-165, d 7: median 83, range 70-101).

Analgesic profile of peroral and topical ketoprofen upon low pH-induced muscle pain.

Topical analgesics are widely marketed for treatment of muscle and joint pain. We have recently developed a model of muscle pain and have used this model to evaluate the efficacy of commercially available topical and peroral ketoprofen in order to evaluate the time- and dose-dependence of analgesia. In the present study, we examined the dose- (0, 50, and 100 mg) and time-dependence (hourly to 8 h) of commercially available peroral and topical ketoprofen.
