Renal biopsy is an invasive procedure used to evaluate the activity and the therapeutic management of kidney disease and kidney transplantation. Objective: The aim of this study was to describe the epidemiological, clinical, and pathological features of kidney disease diagnosed by biopsy in the ivory coast. Materials and Methods: This was a descriptive and prospective study conducted between January 2015 and December 2018 in the Department of Anatomy and Cytology of the Pathology of Cocody (Abidjan) and Bouake. Specimens were obtained from the nephrology department of ivory coast and from teaching hospitals in Togo, Guinea, Burkina Faso, and Mali. Samples were analyzed according to standard renal biopsy procedures. One kidney fragment was fixed in acetic acid formalin (AAF) for optical microscopy examination. The other fragment, soaked in physiological water, was immediately sent for immunofluorescence examination. All renal pathologies were included in this study. The study parameters were frequency, age, sex, origin, occupation, clinical and biological signs, and pathological aspects with optical microscopy, and immunofluorescence. Results: 153 cases (2.23%) of kidney biopsies were examined on a total of 10,573 specimens. ivory coast specimens accounted for 91.5% of cases (n = 140). Nephrotic syndrome (49%) was the most common clinical sign and indication for renal biopsy, followed by acute renal failure (16.3%), chronic renal failure (19.6%), and a combination of chronic renal failure with hypertension (11.18%) and glomerulonephritis (4%). Mean proteinuria was 3.03 g/24h (range, 0.14 to 11.5 g/24h). Histologically, 90.8% (n = 139) were glomerular nephropathies, including 26.6% HIV-associated nephropathy, 17.3% focal segmental glomerulosclerosis, 13.6% nephroangiosclerosis, 11.5% post-infectious glomerulonephritis, 9.3% membranous glomerulonephritis, and 21.6% miscellaneous glomerular nephropathies (n = 30). The incidence of various tubulo-interstitial lesions was

The objective of this study is to analyze the sensitivity of the statistical models regarding the size of samples. The study carried out in ivory coast is based on annual maximum daily rainfall data collected from 26 stations. The methodological approach is based on the statistical modeling of maximum daily rainfall. Adjustments were made on several sample sizes and several return periods (2, 5, 10, 20, 50 and 100 years). The main results have shown that the 30 years series (1931-1960;1961-1990;1991-2020) are better adjusted by the Gumbel (26.92% - 53.85%) and Inverse Gamma (26.92% - 46.15%). Concerning the 60-years series (1931-1990;1961-2020), they are better adjusted by the Inverse Gamma (30.77%), Gamma (15.38% - 46.15%) and Gumbel (15.38% - 42.31%). The full chronicle 1931-2020 (90 years) presents a notable supremacy of 50% of Gumbel model over the Gamma (34.62%) and Gamma Inverse (15.38%) model. It is noted that the Gumbel is the most dominant model overall and more particularly in wet periods. The data for periods with normal and dry trends were better fitted by Gamma and Inverse Gamma.

Open Journal of Endocrine and Metabolic Diseases 2022年第5期12卷 113-121页

作者： Kossi Kodjo Mamadou Mansour Diallo Alpha Mamadou Diallo Koffi Pierre Dago Adelaide Hue Assita Yao Abodo Jacko Adrien Lokrou Department of Endocrinology and Diabetes Yopougon University Hospital Abidjan Ivory Coast Department of Internal Medicine and Endocrinology Sylvanus Olympio University Hospital of Lomé Faculty of Health Sciences University of Lomé Lomé Togo Department of Endocrinology Diabetology Donka Hospital University Hospital of Conakry Conakry Guinea

Background: Diabetic foot is a frequent complication of diabetes, of multifactorial origin, associating nervous and/or circulatory disorders to which infection is often added. Its care is multidisciplinary and requires coordination between different actors. In this context, arterial doppler ultrasound is essential in the diagnosis of diabetic arteriopathy and participates in therapeutic decision-making. The aim of this study was to describe the abnormalities found on Doppler ultrasonography of patients hospitalized for the diabetic foot in the ivory coast. Methods: We conducted a retrospective descriptive study including 235 patients hospitalized for the diabetic foot in the Endocrinology department of the Yopougon University Hospital from February 2002 to December 2015. All records of patients who performed arterial Doppler ultrasound of the lower limbs were selected and the various abnormalities were described. Results: The sex ratio (M/F) was 1.1 (124 men to 111 women). The predominant age group was 61.2 years. Type 2 diabetes was found in 97.4% of cases. The average evolution of diabetes was 8.9 years with extremes of 1 and 32 years. Wet gangrene was the most common type of lesion found in 75.8% of cases. On ultrasonography, 98.7% of the patients had an arterial abnormality of the lower limbs. It was bilateral in 62.2% of cases, dominated by atheromatous overloads and mediacalcosis in 46.4% and 43.8% of cases, respectively. Arterial stenosis was lesions hemodynamically found in 76.3% of cases and arterial occlusions in 32.7% of cases. The amputation rate was 72.7%. Conclusion: This study shows the high frequency of arterial abnormalities in patients with the diabetic foot with a predominantly distal involvement. Arterial Doppler ultrasound of the lower limbs remains an essential tool in the care of diabetic foot. This easily accessible, non-invasive examination has a key role in therapeutic decision-making.

Introduction: The prevalence of Non-communicable diseases (NCDs) has increased so it’s becoming a global public health problem. This problem is also threatening in Sub-Sahara Africa (SSA) country including Ivory Coast. Ivory Coast is a country of 22.6 million people experiencing rapid economic development and social change. All development is typically associated with an increase in non-communicable disease (NCD) risk factors. Our study aimed to determine the prevalence and associated factors of the major risk factors of NCDs among the population of Cocody, Abobo and Yocoboué in the Ivory Coast. Methods: A descriptive and analytical cross-sectional study was conducted and involved 1146 adults of 19 to 60 years from general population in Cocody (urban), Abob (peri-urban) and Yocoboué (rural). The WHO STEPS risk factor survey has been changed a bit and was administered. it contains anthropometric and biochemical measures. Results: The prevalence of NCD risk factors was markedly different across the three sites particularly between urban (Cocody) and rural (Yocoboué) areas. The overall prevalence estimates of the risk factors were 15.2% for current smoking, 57.71% for harmful use of alcohol, 58.84% for low physical activity, 24.71% for sedentariness (sitting at least 7 h), 69.45% for skipping breakfast, 61% for having late dinner and 36% for snacking. Concerning biological risk factor we noticed 40.95% for Overweight/obesity, 52.96% for abdominal obesity, 14.61% for raised blood pressure, 23.37% for raised bloo

Use of the Inverse Slope Method for the Characterization of Geometry of Basement Aquifers: Case of the Department of Bouna (ivory coast)

引用

Journal of Geoscience and Environment Protection 2019年第6期7卷 166-183页

作者： Rock Armand Michel Bouadou Kouamé Auguste Kouassi Francis Williams Kouassi Adama Coulibaly Théophile Gnagne Laboratory of Geosciences and Environment UFR of Sciences and Management of the EnvironmentUniversity of Nangui AbrogouaAbidjanIvory Coast Department of Science and Technology of Water and Environmental En-gineering UFR of Earth Sciences and Mineral ResourcesUniversity of Félix Houphouet-BoignyAbidjanIvory Coast

The inverse slope method (ISM) was used to interpret electric sounding data to determine the geoelectric parameters of the alteration zones (continuous media) and rocky environments (discontinuous environments) of the Bouna Department. Having both qualitative and quantitative interpretation, the inverse slope method (ISM) has the ability to determine the different geoelectric layers while characterizing their resistivities and true thicknesses. In the Bouna department, this method allowed us to count a maximum of four (4) geoelectric layers with a total thickness ranging from 12.99 m to 24.66 m. The alteration thicknesses calculated by the ISM in comparison with those measured in the boreholes showed a linear agreement of the coefficient of determination R2 = 0.8269 with the support of the Nash criterion which showed that this method gave thicknesses of alteration close to 76.76% of that obtained during the drillings.

This study aims to characterize the climatic variability in the South-East of ivory coast and to show its impact on the supply of water resources. To do this, statistical and hydrological methods were applied to climatic data collected at the Marc DELORME Research Station of the CNRA. The statistical trend tests on this data revealed a significant decrease in precipitation and an increase in temperature, insolation and evaporation. Statistical break methods indicate a rainfall break in 1982 which marks a modification of the rainfall regime thus translating a drop in rainfall of 15%, a recession in the frequency of rainy days in general and in particular in rainfall heights between 10 and 30 mm and greater than 50 mm. This break is accompanied by a shortening of the rainy seasons, with average rainfall durations ranging from 54 days (short rainy season) to 104 days (great rainy season). Despite the disturbances in the different seasons of the year, the monthly rainfall regimes in the area have not changed. The assessment of the effects of drought on water resources using the Standardized Precipitation and Evapotranspiration Index (SPEI) for three-time scales (1 month, 3 months and 12 months) indicates a severe drought ranging from 3% to 7% over the period 1961 to 2018. However, despite the presence of this severe drought, the intensity of the drought was found to be moderate on all time scales. The Thorrnthwaite method was used to highlight the impacts of this climatic variability on the region’s water resources. The average annual recharge estimated at 402 mm, has been reduced to 153 mm during a deficit period, a decrease of about 62%. The average annual runoff, which was 294 mm, fells to 257 mm, a decrease of about 13%. This recorded decrease in the water infiltrated after the rainfall break (1983-2018), explains the heterogeneous decrease in the depth of the water table.

The availability of groundwater of acceptable quality has become a difficult challenge to meet in many countries, particularly Côte d’Ivoire. The State of Côte d’Ivoire and rural populations are building hydraulic infrastructure for this purpose. However, the quality of water coming from these infrastructures remains to be determined. This study therefore aims to analyze certain physicochemical parameters of the groundwater of Gloazra, Kouezra and Trahonfla. These are temperature, pH, electrical conductivity, TDS, salinity level, hardness, alkalinity, chloride content and bicarbonate. To determine the pH, electrical conductivity, temperature, TDS, and salinity rate, an electrochemical analysis was carried out. The titrimetric analysis made it possible to determine the chloride and bicarbonate content, alkalinity, and hardness. The results indicate that the studied groundwater is soft and acidic with good mineralization. This water does not present a health hazard to consumers but can affect hydraulic equipment and household containers.

Journal of Power and Energy Engineering 2019年第11期7卷 28-34页

作者： Kouassi Kouamé Auguste Douagui Gountôh Aristide Mangouaoi Mangoua Jules Coulibaly Kafana Kouassi Francis Williams Geosciences and Environment Laboratory UFR of Sciences and Environmental ManagementNangui Abrogoua UniversityAbidjanCote d’Ivoire UFR Environment Laboratory of Environmental Sciences and TechnologiesJean Lorougnon GuedéDaloa UniversityDaloaCote d’Ivoire

This work concerns the collecting field of the Abrobakro site, the objective of which is to determine the thickness of the layers crossed during drilling from electrical logging in order to propose the equipment plan for the various boreholes. The electrical logging data sheets, particularly those on resistivity and expeditious granulometry using a 1.25 mm and 2 mm mesh sieve, were used. The layer thicknesses are determined with the inflection points on the graphs. The electrical logging shows that the sands in the study area have resistivity values between 400 and 5000 Ω.m. The decrease in resistivity observed at 50 m for all boreholes shows that the static level of the groundwater is at this depth. The results of the accelerated granulometry show that the first 20 meters contain more fine particles and coarse to very coarse sands from 20 m. The granulometry of the screen laying areas shows that the 1.5 mm slot openings are best suited for all drilling in the Abrobakro collecting field. The diameter d10 of the aquiferous sands of the collecting field is close to 1.25 mm.

As part of the drive to improve coffee and cocoa production in ivory coast, studies are carried out to identify soils that are favourable for these crops. It is therefore necessary to orientate soil investigations based on reliable criteria that best discriminate soil cover. With this in mind, this study is being carried out to help improve survey methods by mapping soil landscapes. It uses GIS and weighted multicriteria analysis. To do this, satellite images were processed and the geological map of the square degrees of M’Bahiakro and Daloa was reclassified. The results show that relief is the main factor in soil landscape differentiation, with respective weights of 0.58 and 0.67 for the forest and pre-forest zones. In contrast, the weight of geological formation in soil landscape differentiation remains low (0.05 for the forest zone and 0.07 for the pre-forest zone). The criteria used on the base of aggregation sum methods have made it possible to formulate soil landscape mapping prediction functions according to agro-ecological environments in the humid intertropical zone. This is essential for the orientation of soil survey work. Nevertheless, other comparative methods, such as the coding mapping method, could provide elements for discussion to validate the models.

Conceptual Model of Aquifers in the Bedrock Zone of the MarahouéWatershed (Centre-West of ivory coast)

引用

Journal of Geoscience and Environment Protection 2022年第7期10卷 229-256页

作者： Kouassi Désiré Bouatrin Innocent Kouassi Kouame Aristide Gountôh Douagui Kouamé Auguste Kouassi Bi Tié Albert Goula Geosciences and Environment Laboratory Department of Environmental Sciences and Management Nangui University Abrogoua Abidjan Ivory Coast

Marahoué watershed, located in the Center West of Côte d’Ivoire, has experienced significant population growth in recent decades. And a major economic boom linked to intense agricultural activity and the presence of certain industries. This population growth is also accompanied by seasonal water shortages. Hence it needs to better manage the basin’s groundwater, which is a permanent resource and more resistant than surface water to climatic hazards. The objective of this study is therefore to propose a conceptual model of hydrogeological flow for the sustainable exploitation of groundwater resources in the Marahoué watershed. The establishment of the conceptual model was carried out in two stages. The first step consisted in defining the stratigraphic units. For this purpose, three units have been defined. These are the layer of alterite, the useful fissured horizon and the sound basement. The thickness of the layer of alterite varies from 0 to 80 m with an average of 26 m. As for the useful fissured horizon, its thickness is between 43 and 46.5 with an average of 45 m. In addition, the roof of the basement presents a slightly uneven morphology with a North-West, South-East dip and the altitudes are between 150 and 390 m. The second step corresponds to the phase of determining the hydrodynamic parameters. During this phase, the crack porosity, the transmissivity, the conductivity, the storage coefficient, the hydrological balance and the piezometric map were determined. Indeed, these parameters (the crack porosity, the transmissivity, the conductivity and the storage coefficient) confirm not only the heterogeneity of the medium but that the cracked horizon is sufficiently porous to be assimilated to an equivalent continuous medium during the simulation.
