Comparison between sirolimus- and paclitaxel-eluting stent in T-cell subsets redistribution.

We sought to investigate the effects of 2 different coronary drug-eluting stents on the distribution of central or effector memory T cells circulating in the coronary sinus of patients with coronary artery disease who underwent percutaneous coronary revascularization. We randomly assigned 43 patients (mean age 65.4 +/- 4.

Altered trafficking of CD8+ memory T cells after implantation of rapamycin-eluting stents in patients with coronary artery disease.

Aim of this study was to investigate the effects of implantation of different coronary drug-eluting stents on trafficking of central (T(CM)) or effector (T(EM)) memory T cells in the coronary sinus of patients with coronary artery disease (CAD) undergoing percutaneous coronary revascularization. Thirty-two patients presenting with stable coronary disease and angiographically proven stenosis of left descending coronary artery were randomly assigned to treatment with rapamycin-eluting, paclitaxel-eluting or bare metal stents. Heparinized blood samples were obtained from the coronary sinus either before or 20 min after stent implantation.

[CIN: multicentric study of therapeutic strategies].

Background: Cervical Intraepithelial Neoplasia (CIN) is a dysplastic lesion that precedes cervical cancer. The diagnosis is made by colposcopic, cytologic and bioptic exams. Therapy may be physical, pharmacological or surgical.

[Bleedings during the third term: which complications?].

Background: The aim of this research was to study the maternal and prenatal complications which may occur in the abruptio placentae and in placenta praevia.

Methods: All the patients who were hospitalized in the Obstetrics and Gynaecology Department of the Policlinico Umberto I, from January 1993 to July 2000 have been studied. Moreover, a comparative study between the onset of complications of the two pathologies considered and the ones found in a control group was carried out.

[Early isovolumetric relaxation: correlation with the densitometric analysis of coronary stenosis].

Early relaxation is characterized by a segmental outward wall movement during isovolumic relaxation. There is still no general agreement as to its significance. Some Authors have considered the phenomenon to be a specific marker of isolated coronary narrowing, others have regarded it as a normal variation of left ventricular relaxation and still others concluded that it is a compensatory phenomenon to local ischemia in another region.
