Abstract

We investigated the immunohistochemical expression of endothelial cell adhesion molecules in 17 cases of idiopathic inflammatory myopathies. The present study revealed: 1) a constitutive expression of ICAM-1, ICAM-2 and PECAM-1, but not VCAM-1, LFA-3 and E-selectin, on endothelial cells in normal muscles; 2) a modification of cell adhesion molecules expression in idiopathic inflammatory myopathies with an increased expression of the expressed molecules constitutively; an expression of LFA-3 and VCAM-1 on capillary endothelial cells in polymyositis/inclusion body myositis, these molecules being only observed on endothelial cells of some arterioles in dermatomyositis; 3) an expression of all these molecules on inflammatory cells in inflammatory myopathies. In dermatomyositis, the expression of ICAM-1 and VCAM-1, predominated on mononuclear cells located near vessels. In polymyositis/inclusion body myositis, a strong expression of ICAM-1, VCAM-1 and LFA-3 was present on inflammatory cells invading non necrotic muscle fibers; 4) absence of E-selectin on endothelial and inflammatory cells in all cases.

Abstract

Slow-release oral morphine sulfate ( SM) is one of the most abused prescription opioids in France. However, the regional feature of the abuse of morphine is poorly documented. To investigate the abuse of SM in a French administrative region, a multisource approach was applied. The first approach was based on SM exposition at national and regional level using the OPPIDUM survey. In a second approach, we analyzed a drug reimbursement database to assess the magnitude of SM abuse in Languedoc-Roussillon ( LR) region. A clustering method was applied to classify patients and to describe the profile of deviant patients. The third approach was based on a self-administered anonymous questionnaire, proposed to patients seen in addiction care centers in the LR region and consuming oral SM. The OPPIDUM study showed that in most regions, where the prevalence of heroin use is higher than the national average of 9.1%, SM consumers were fewer. With the clustering method, three subgroups were identified. One of them gathered 35 users (3.2%) with a deviant behavior characterized by significantly more dispensations, dispensing pharmacies, and prescribers. These subjects were mainly men, younger, and more consumers of benzodiazepines and opioid maintenance therapy than the others. The third study allowed specifying that SM was mainly injected (93.7%), bought in the street (80%), and used because of unavailability and the poor quality of heroin (33.9%). The three proposed approaches are complementary and help to clarify the abuse of oral SM, while assessing the motivations of this abuse. [ABSTRACT FROM AUTHOR]

Abstract

The paper describes a procedure for the acquisition and the analysis of angiograpbic images that allows to study thc Kinetic of a dye in the retinal network. In perticular, the procedure computers automatically a set of parameters extracted from regions of interest defined by the user. Tbc efficiellcy of the procedure has been tested by comparison with ophthlmogical evaluations by studying, the dye kinetic in animals treated with different types of antihaemorragic drugs.

Abstract

This paper aims to predict a breast cancer patient's prognosis and to determine the most important prognostic factors by means of logistic regression (LR) as a conventional statistical method, multilayer backpropagation neural network (MLBPNN) as a neural network method, fuzzy K-nearest neighbor algorithm (FK-NN) as a fuzzy logic method, a fuzzy measurement based on the FK-NN and the leave-one-out error method. The data used for breast cancer prognostic prediction were collected from 100 women who were clinically diagnosed with breast disease in the form of carcinoma or benign conditions., Papers from 23rd Annual International Conference of the IEEE Engineering in Medicine and Biology Society, October 25-26, 2001 held in Istanbul, Turkey.

150. Haemodynamic Assessment by Transvalvular Impedance Recording.

Author

Gulizia, M. M., Bongiorni, M. G., Soldati, E., Arena, G., Giannola, G., Bartoli, C., Barbetta, A., and Gregorio, F.

Abstract

Effective haemodynamic sensing would open the way to the autoregulation of a number of pacemaker functions, which could thus be integrated into a single control system. The TVI sensor can be proposed to play this crucial role, allowing the assessment of systolic and diastolic modifications in ventricular volume by means of conventional pacing leads.
