Effect of atmospheric pollutants on the air quality in Tunisia.

This paper presents the evolution of Saharan dust advection when the PM10 (particles with an aerodynamic diameter below 10 μm) concentration exceeds standard limits in different Tunisian sites. Meteorological and concentration data (from 2004 to 2010) obtained from several monitoring stations and in situ measurements were used to identify African dust change in seasonal occurrence, their source origin, and their impact on surface PM10 concentrations. We pointed out that the Saharan dust contribution caused frequently the surpassing of the maximum number of days in excess of EU standard limits as well as of the maximum yearly average in the Mediterranean Tunisian coasts.

[How to diagnose hypertension in the elderly?].

The management of hypertension in the elderly requires careful diagnosis, which is not always easy in this population because of the increased variability of blood pressure. The practitioner is faced with three questions in this diagnostic approach: how to evaluate the patient's real blood pressure level, how to assess the degree of cardiovascular impairment and concomitant disease and finally how to evaluate the subject's global cardiovascular risk. Self-monitoring of blood pressure, which allows measurement of blood pressure by the patient himself in his usual environment, provides a better assessment of the elderly patient's real blood pressure level.

[Evaluation of blood pressure control by repeated ambulatory automatic blood pressure measurements].

Unlabelled: The aim of this study was to compare the evaluation of blood pressure control in using an automatic blood pressure device (ABPD) and an ambulatory blood pressure measurement (ABPM).

Method: 41 patients with essential hypertension (HTA) were screened prospectively from April to June 2000 (22 men and 19 female) mean age 63 years old, 2.6 antihypertensive drug per patient).

[Effectiveness of the treatment of arterial hypertension in a specialized service. An audit using the automatic measurement of arterial blood pressure].

Unlabelled: The ineluctable fade out of mercury sphingomanometer pressure device involve the necessity in using automatic blood pressure systems. In parallel the recent PHARE II study witness of a lack in the control of hypertension in general practice. In the basis of an automatic blood pressure device measure, we had try to know the efficiency of blood pressure contrôl (BPC) in a specialised consultation.
