This study is a part of a global approach in which, the main purpose is to understand the reasons behind the upsurge of flood events in the peri-urban area of the city of Dakar. Hydrological and hydraulics simulations were carried out to assess the risks of overflowing of the Lake Warouwaye after a so-called exceptional rain. Data were collected through field surveys, as well as site observations of dwellings before and after rain episodes. The simulations were performed using EPA’s Storm Water Management Model (SWMM) software with input data obtained from sub-software and supervisory applications such as Google Earth, Excel, and Global Mapper. The simulation results show factors of natural and anthropogenic origin may contribute to dysfunction hydrological elements such as the watershed capacity to drain and store water. In light of the results of this study, institutional governance efforts are to be made and to be sustained in order to reverse the tendency to occupy rainwater natural flow channels. It will also be necessary to involve the first actors who are the potential victims of flooding caused by the recurrent overflow of reservoirs.

Introduction: The involvement of the endothelial dysfunction (ED) in arterial hypotension (AHPT) post of spinal anesthesia (sa) has not been established. Objective: To determine if there is a relationship between ED and AHPT observed during the 1st 15 minutes after sa. Population and Methods: The study concerned 40 people who were to benefit from a programmed herniorrhaphy under sa and 40 controls (sa-). The correlations between mean plasma concentrations of endothelin-1 (CmET-1, pg/ml) and Vascular Cell Adhesion Molecule-1 (CmVCAM-1, pg/ml) taken from sa+ one hour before (H0), then 15 minutes after the sa (H15) and the mean arterial pression (AMP, mmHg) with heart rate (bpm) were analyzed (p Results: CmET-1 and CmVCAM-1 of sa- were 1.07 and 3.34, respectively, compared to 1.12 (p = 0.735) and 3.57 (p = 0.862) in sa+ at H0 and H15. In sa+, at H15, CmET-1 was 1.13 (p = 0.823) and CmVCAM-1 was 3.57 (p = 0.257). In sa-, a negative correlation existed between CmET-1 and CmVCAM-1 (r = -0.438;p = 0.005). Conversely, in sa+, whether at H0 (r = -0.31;p = 0.051) or at H15 (r = 0.024;p = 0.883), no correlation existed between CmET-1 and CmVCAM-1, nor between MAP and ED markers (r = 0.111;p = 0.325). Conclusion: These results show that there is no relationship between the AHPT which occurs during the first fifteen minutes post sa, CmVCAM-1 and CmET-1. Moreover, these data suggest that ED is not involved in AHPT post sa.
