The paper explores the degree of pollution of organochlorine pesticides in fish and water in the dam at Kpassa on a tributary of Okpara River that is pumped by Benin National Water agency (SONEB) in supplying drinking water to supply the city of Parakou. Doing so, fourteen parameters of organochlorine are analyzed. Most of obtain organoclorine concentration in water and fish below is indicated critical values. However, DDT and endrine concentration in water is slightly above legal tolerable values. Hexachlorobenen and dieldrine concentrations are three times higher than legal limit value while aldrine is ten times higher. However, heptachlore is double concentrated in fishery while aldrine (endrine, dieldrine aldrine, lindane, hexachloro-benzene, DDT) is found in the dam fish and surface water three times concentrated than tolerated value. These levels of concentrations result from the intensification of organoclorine pesticide used in agriculture especially in cotton production. These are caused by the chemical application accumulated in soil and through the food value chain system. Therefore, it is very important to extract sediment from the reservoir by dredging in oder to renew the ecosystem of the dam. To persistently manage the basin water resources, it is imperatively important to observe a significant behaviour changed from all stakeholders.

Introduction: Double discordance or corrected transposition of the great vessels is a rare congenital heart disease. It is an atrioventricular and ventriculo-arterial mismatch. It is a complex and unusual form of congenital heart disease. Often asymptomatic, in its isolated form, bradycardia, murmur and cyanosis can be a mode of revelation. Case presentation: We report the case of an 11-year-old child, asymptomatic at birth, after he started to have dyspnea on exertion, recurrent bronchitis, motivating a cardiological consultation. On cardiac physical examination, the heart sounds regular, not rapid at 81 BPM with a grade 3-4/6 systolic murmur at the 4th left EIC (Intercostal space). EKG (electrocardiogram) shows PR interval at 0.20 seconds. Cardiac ultrasound reveals atrioventricular discordance, vascular malposition, anterior aorta, the two vessels placed side by side, minimal pulmonary insufficiency, a small leak at the levels of the mitral and tricuspid valves, dystrophic pulmonary valves with an average gradient of 91 mmHg, max at 158 mmHg. Regular follow-up has been recommended through the performance of a clinical examination and cardiac ultrasound. Conclusion: The double discordance can be asymptomatic, and survival can be long in the isolated forms, but the evolution is not always benign, especially in the associated forms. It depends on the function of the systemic right ventricle and associated abnormalities.

Journal of Geoscience and Environment Protection 2019年第8期7卷 49-68页

作者： Gabriel Etienne Ake Kan Jean Kouame daouda fofana Oularé Sekouba Affoué Bénédicte Koffi Jean Patrice Jourda Laboratory of Science and Technology of Water and Environment (LSTWE) UFR of Earth Sciences and Mineral Resources University of Félix Houphouet-Boigny Abidjan Cote d’Ivoire University Center for Research and Application in Remote Sensing (UCRARS) Abidjan Cote d’Ivoire

The study highlights the potential recharge areas of the aquifers of the Department of Aboisso for an adequate and rational management of their use. The methodology used consisted in the identification of parameters (land use, soil types, drainage density, slope, induced permeability and alteration thickness) allowing infiltration and their expression as thematic maps. A weighting of these parameters was made by the multicriteria analysis method of Saaty. The integration to GIS conducted to elaborate the map of the potential recharge area of the aquifers for the Department of Aboisso. It brings to light five recharge level classes (bad: 20%;mediocre: 19%, medium: 45%;good: 15% and very good: 1%) in the study area. That map reveals the dominance of good recharge areas covering 61% and practically all over the studied area. They are generally characterized with gentle slopes coupled with mosaics of cultivations and forests, and high induced permeability allowing better infiltration. The zones of low recharge cover 39% of the department’s area, and are mainly located in urban areas inside the streams. This study exhibited that the land use is the preponderant parameter influencing the recharge in base area. This map could be considered as an excellent support for all kinds of activities especially to implement planning in the Department of Aboisso, the setting up of drilling broadbands and the choice of future sites for landfills or landfill of wastes to protect groundwater from any pollution.

Introduction: High blood pressure is a major public health problem worldwide due to its frequency and cardiovascular complications. Adherence to treatment for chronic diseases is a global problem. The aim was to study therapeutic adherence in hypertensive patients followed in ambulatory. Materials and Methods: This was a cross-sectional, descriptive study with prospective recruitment that took place from July 1 to December 31, 2022 (6 months) in the cardiology department of the university hospital of Kati. The variables studied were sociodemographic data, cardiovascular risk factors, comorbidities, the possession of insurance and compliance (the Girerd questionnaire was used to assess adherence). Results: A total of 1182 patients were consulted, including 887 for hypertension, a frequency of 75%. Fifty-six patients were included in the study. The average age was 58.18 ± 13.25 years with extremes of 30 and 80 years. There was a female predominance (75%) with a sex ratio of 0.3. The majority of patients lived in urban areas (89.3%). Out-of-school patients accounted for 44.6%, more than half of patients or 55.4% had no income, patients with medical coverage accounted for 67.9% of cases. The main risk factors were physical inactivity (25%) followed by smoking 14.3%. More than 71% of patients had a compliance problem and the main reasons were forgetting to take the drug with 73.2%, followed by delayed treatment of 50% and drug discontinuation of 28.6%. Conclusion: Compliance is a real challenge and a major public health issue. This study allowed us to find a real problem of compliance in our hypertensive patients. There was a statistically significant relationship between drug adherence and forgetting to take the drug and drug discontinuation.

A foreign body in the urethra is the presence of an object in the urethra. They are often secondary, either to an erotic curiosity, û or to psychiatric disorders. The diagnosis remains clinically aided by imagery. Treatment is most often endoscopic, but in some cases the use of open surgery is necessary. We reported the case of an 80-year-old man with no history of behavioral disorders;a wooden rod was inserted into the urethra to empty his bladder. The care consisted of a meatoplasty under locoregional anesthesia. Upon discharge, the patient had a good urine flow.

Bladder Extrophy is a rare urogenital malformation of the penis and bladder. This is an impressive fact at birth, due to the absence of the anterior bladder wall and the dorsal side of the penis. We report the clinical observation of a 21-month-old child who consults for urine incontinence from birth, when physical examination showed complete bladder extrophy. The reconstructive surgery allowed forming a bladder reservoir associated with a repair of the penis at the same time. Bladder extrophy is a benign condition whose operative consequences can be simple but urinary incontinence is not uncommon after reconstitution.

Introduction: The metabolic syndrome is a clinical entity defined by the association in the same subject of four of the following five factors: abdominal obesity (or android), type 2 diabetes, hypertension, hypo HDL cholesterolemia, hypertriglyceridemia. The aim of the work was to study the epidemiological, clinical-biological profiles and complications of patients in the cardiology and internal medicine department of the Mother-Child CHU “Luxembourg”. Materials and Methods: We carried out a cross-sectional study, from September 2019 to June 2020 in the cardiology and internal department of the mother-child CHU “Luxembourg”. All patients with metabolic syndrome admitted to the two departments who agreed to participate during the study period were included in the study. These patients meet the 2009 harmonization attempt criteria (IDF 2009). The variables studied were: socio-demographic characteristics (sex, age, profession), pathological history, clinical signs (functional signs, BMI, waist size), paraclinical signs (ECG, cardiac ultrasound, laboratory assessment) and complications. Results: A total of 104 patients were included. The female sex represented 58.65% of cases. The 60 to 69 age group was the majority with 40.78%, housewives occupied 41.34% of cases. Diabetes, arterial hypertension and dyslipidemia were the most represented cardiovascular risk factors with respectively: 80.77%, 79.81% and 53.85%. Visual blurring was the most common functional sign with 23.08% of cases. Moderate obesity was observed in 34% of patients. Waist circumference was high in 39.53% of male patients and 37.70% of female patients. Cardiac ultrasound found a severely collapsed ejection fraction in 25% of patients. HDL-c levels were low in 64.52% of male patients and 75% of female patients. The most observed complications were: dyslipidemia (53.85%), stroke and renal failure with 23% respectively

Introduction: Acute coronary syndrome is often the first event of coronary disease of young subjects. Objective: To study sociodemographic, clinical, paraclinical, therapeutic and evolutionary aspects of acute coronary syndrome of young subjects. Patients and Methods: Descriptive cross-sectional study with prospective recruitment from October 01, 2020 to March 31, 2022. Were included all patients admitted for acute coronary syndrome whose age was less or equal to 45 years and who had undergone coronary angiography at the Mother-Child University Hospital on Luxembourg from Bamako. Results: During the study period, we collected 60 patient files out of 198. These 60 patient files met our inclusion criteria. Hospital frequency was 30.30%. Average age of patients was 40.43 ± 3.9 years. Sex ratio M/F was 5.3. Main cardiovascular risk factor was smoking tobacco (23.42%), followed by dyslipidemia (13.92%). Functional signs were dominated by angina 62% followed by dyspnea 25.3%. Persistent ST-segment elevation on electrocardiogram was present in 76.4%. Left ventricular systolic dysfunction was present in 26.5%. Time to first medical contact was more than 12 hours in 62.7% of cases. Radial approach was adopted in 94% of cases. Coronary angiography was pathological in 85% (n = 51) of cases. Lesions were single-vessel disease in 47.1% and culprit artery was anterior interventricular in 51% of cases. Dual anti-platelet aggregation was aspirin and ticagrelor in 91.8% of cases. Angioplasty was performed in all patients who had significant abnormalities at coronary angiography. In-hospital mortality was 3.9%. Conclusion: Acute coronary syndromes exist in young Africans with a male predominance. Main cardiovascular risk factor is smoking tobacco. Coronary lesions are single vessel disease in the majority of case. Most of patients meet medical team after 12 hours. Time to first medical contact is a main challenge in our country.

Introduction: Acute coronary syndromes (ACS) are a diagnostic and therapeutic emergency. Objective: Studying the feasibility, difficulties and results of coronary angioplasty in acute coronary syndromes at the Luxembourg Mother-Child University Hospital in Bamako. Patients and Methods: Cross-sectional, descriptive study with prospective recruitment over 18 months from September 2020 to February 2022. All patients aged at least 18 years old admitted for SCA and having undergone PCI during the study period were included. Result: We collected 249 patients for SCA, of whom 160 underwent angioplasty, either an angioplasty/SCA ratio of 0.64. The average age of the patients was 59.54 ± 11.62 with extremes of 32 and 92 years. The age group of 45 to 65 years was the most representative. The predominance was male, sex ratio of 2.4. The main cardiovascular risk factors were high blood pressure (58.23%) and diabetes (45.78%). Persistent ST-segment elevation on the electrocardiogram was present in 71.48%. The treatment time was more than 12 hours after the first medical contact in 95.5%. The approach was radial in 96.5% of cases. Coronarography was pathological in 91.16% of our patients. The lesions were tri-truncular in 34.13% with the anterior inter ventricular as culprit artery in 72% of cases. The majority of patients (64%) had undergone angioplasty with implantation of an active stent. Angioplasty was performed successfully in 98% and per procedural mortality was 1.87%. Only 6.45% of ACS with ST elevation benefited from primary angioplasty. Conclusion: Percutaneous coronary intervention is performed routinely in our center with satisfactory results. Difficulties exist, related to the diagnostic delay of ACS and the high cost of angioplasty.

Scleroderma (or systemic sclerosis) is a disease characterized by abnormalities in the functioning of small blood vessels and the immune system, ultimately leading to inflammation and excessive fibrosis of the skin and various organs, including the heart. Management must be multidisciplinary, to avoid complications that are often serious. We report the case of a 20-year-old patient with no known cardiovascular history who consults for dyspnea, and retrosternal pain associated with a dry cough. On physical examination, she had tachycardia, swelling of the lower limbs, jugular turgidity, and deafening heart sounds. Cardiac Doppler ultrasound shows dilation of the right cavities, paradoxical septum and significant pulmonary arterial hypertension, pericardial effusion of medium abundance. On oral examination, it presents an ulceration of the lips, dermatological examination finds scattered hypo chromic spots in the body, more accentuated in the face. Before the hypo chromic dermatosis, a dermatological consultation was carried out with an autoimmune assessment that came back positive for systemic scleroderma.
