This is a review of the first 10 coronary artery bypass surgeries performed by the local team. The mean age was 62 years old [45 - 74]. The patients were predominantly male, with a M/F ratio of 4:1. Cardiovascular risk factors were mainly myocardial infarction (MI) (60%), hypertension (50%), obesity (40%) and diabetes (30%), with at least two risk factors per patient. Angina was the main symptom (80%). The average time from presentation to surgery was 8 months. The mean Euroscore 2 was 2.92 ± 1.65 [1.33 - 6.60]. Coronary angiography revealed an average of 2 lesions per patient, with 3-vessel involvement in 70% of cases: the Interventricular artery (IVA) (100%), the right coronary artery (90%) and the circumflex artery (70%). On echocardiography, the mean Left ventricular ejection fraction (LVEF) was 59% [33% - 76%]. All patients underwent median sternotomy with bypass grafting. The average duration of the cardiopulmonary bypass was 150 min [46 - 275 min];that of aortic clamping, 120 min [43 - 232 min]. The grafts used were internal thoracic artery (ITA) in 100% of cases (80% on the left and 20% on the right), and the great saphenous vein (GSV) in 60% of cases (50% on the left and 10 on the right). Double bypass was performed in 60% of cases, single bypass in 30% and triple bypass in 10%. The bypasses were performed on the IVA (100%), the middle lateral of the circumflex (30%) and the bisector (20%). The average time to extubation was 11 hours and the length of stay in the intensive care unit was 7 days [03 - 17 days]. One patient had a reoperation on Day 0 post-op. The average hospital stay was 13 days [06 - 27 days]. Complications occurred in nine of the patients (90%), with a predominance of infectious and neurological complications. Overall operative mortality was 3%, all in intensive care.

Asthma is one of the most common chronic respiratory pathologies worldwide. The cost of its treatment, particularly for populations in developing countries like Senegal, requires an alternative which consists of developing research into new therapeutic approaches with the use of plants from traditional pharmacopoeia. The objective of this study was to determine whether the hydroalcoholic extract of Terminalia avicennioides leaves has a preventive effect on the constriction of tracheal smooth muscle induced by Acetylcholine in Wistar strain rats. Methods: The species used in our experiments were male Wistar rats aged between 12 and 14 weeks. Rings of rat trachea were suspended in isolated organ chambers connected to tension sensors. Two pharmacological agents were used: acetylcholine, for its constrictor effect and adrenaline, for its dilating effect on the pulmonary trachea. Our plant material consisted of a hydroalcoholic extract of Terminalia avicennioides leaves. The experimental protocol was that of the preventive model which consisted of impregnating these rings with the extract at a defined concentration then testing its contractility in the presence of Acetylcholine which was the contractile agonist used in this study. The preventive effect of the extract was studied with an Acetylcholine contraction range on rings pre-incubated with Terminalia avicennioides extract. Results: The results showed that Acetylcholine contracts the trachea and the increase in its contractility was dependent on the dose of Ach added cumulatively (10−5 to 4 × 10−5 mol/l). The administration of the hydroalcoholic extract of Terminalia avicennioides leaves led to a modification of the contractile response to Acetylcholine. Indeed, this extract induced a significant attenuation of the contractile responses of the treated tracheal rings compared to those untreated. Conclusion: Terminalia avicennioides had a relaxing effect on tracheal smooth muscle and this effect

World Journal of Cardiovascular Diseases 2024年第2期14卷 77-87页

作者： Youssouf Camara Hamidou Oumar ba ibrahima Sangaré Boubacar Sonfo Coumba Adiaratou Thiam Mahamadou Sékou Diakité Koniba Diarra Karamba Touré Massama Konaté Ichaka Menta Cardiology Department University Hospital Professeur Bocar Sidi Sall Kati Kati Mali Cardiology Department University Hospital Gabriel Touré Bamako Mali Cardiology Department Mali Hospital Bamako Mali

Introduction: Exercise stress testing (on a treadmill or ergometer bicycle) is an important test in cardiology for diagnosing myocardial ischemia. This test in Mali is still in its beginning compared to other countries in the sub-region. The lack of data in Mali prompted this study, which aimed to evaluate the indications of this activity and its diagnostic contribution to cardiology in Mali. Materials and Methods: This was a retrospective, descriptive study. The study was conducted at the “TOUCAM” medical clinic in Kati based on the analysis of stress test reports between January 2016 and August 2022. Result: During the study period, we documented 73 patients who underwent exercise testing on a bicycle ergometer for suspected coronary heart disease. The mean age of our patients was 47.5 ± 13.8 years (14 and 79 years). Males accounted for the majority (78.1%). The sex ratio is 3.5. More than half of our patients were overweight or obese (77.1%). Hypertension and diabetes affected 52.1% and 25.8% of patients, respectively. 20.8% of patients had coronary artery disease. renin-angiotensin-aldosterone system blockers (56.8%) and beta-blockers (51.3%). The main indications were chest pain (63.0%) and ischemia detection (15.1%). A modified STEEP protocol was used. The majority of our patients (71.2%) achieved at least 85% of their maximum theoretical heart rate. The main reason for the termination of the study was fatigue (57.3%). The average duration was 11.3 ± 4.2 minutes. 24.7% thought the stress tests were positive and 17.8% thought they were controversial. Conclusion: This study demonstrates the importance of stress testing in the diagnosis and treatment of ischemic heart disease, especially in settings where we have very limited access to coronary angiography.

Introduction: Heart failure is a major public health pandemic, particularly in Africa, where its prevalence continues to increase. In northern Mali, few data exist, hence the interest of this study with the objective of studying the epidemiological, clinical and therapeutic and evolutionary aspects of Heart failure at the regional hospital of Gao. Patients and Methods: This was a cross-sectional, descriptive study that took place from July 2022 to June 2023 in the medical department at Gao Hospital. Results: The hospital prevalence of heart failure was 44.1%. The mean age was 47.30 ± 20 years (range: 16-88). Hypertension was the most common with 46.1%, followed by a sedentary lifestyle, and diabetes with 18.2% and 8.3% respectively;NYHA stage III-IV dyspnea was found in 83.9%. Reduced EF heart failure was present in 110 patients (76.9%), seventeen cases with moderately reduced EF (11.9%) and sixteen patients had preserved EF (11.2%). Global heart failure was the dominant (91.6%). The main etiologies of heart failure were dominated by hypertensive heart disease in 46 patients (32.2%), followed by postpartum cardiomyopathy with 43 cases (30.1%), primary dilated cardiomyopathy in 18 patients (12.6%), ischemic heart disease in 16 patients with 11.2%. Seven cases of valvular heart disease, or 4.9%. The evolution was favorable under treatment in 104 patients or 72.7%. In-hospital mortality was 14.7%. Conclusion: Heart failure is a common condition in sub-Saharan Africa, particularly in our country.

Introduction: The severity of Sars-Cov-2 infection is associated with the development of acute respiratory distress syndrome (ARDS). The progression to ARDS appears to be driven by a major inflammatory mechanism potentially sensitive to corticosteroids. Observation: This article describes the case of an elderly patient was admitted to emergency departments for intense asthenia, accompanied by motor diarrhoea, dyspnoea with desaturation in ambient air, in a context of strong suspicion of infection linked to COVID-19. The article also reviews the existing literature on the diagnosis and treatment of this severe form of the disease. Conclusion: Corticosteroids, and in particular dexamethasone, have been shown to be effective in the management of patients with COVID-19, an oxygen-releasing disease.

Pre-Rupture Aneurysm of the Juxta and Sub-Renal Abdominal Aorta in Early Pregnancy: A Case Report

引用

Open Journal of Obstetrics and Gynecology 2022年第9期12卷 999-1003页

作者： Ibrahim Rahadat Astou Coly Niassy dialtabé ibrahima guessé ba Papa Adama Dieng Marie-Édouard Faye Jean-Charles Moreau Gynecological and Obstetric Clinic Aristide Le Dantec Dakar Senegal Cardio Thoracic Surgery Dakar Senegal

Aneurysm of the abdominal aorta is the result of a weakening of the arterial wall and corresponds to abnormal dilatations of the arteries defined as an increase ≥ 50% of the arterial diameter compared to the normal segments. A long asymptomatic, abdominal aortic aneurysm can be a catastrophic maternal-fetal situation due to the high risk of rupture induced by pregnancy. A rare association between aneurysm and pregnancy poses a problem of diagnosis and standardized management. The lack of knowledge of this condition regularly leads to a delay in management, which is a source of excess mortality. We report the case of a patient with a progressive pregnancy of 12 weeks of amenorrhea who presented with a large sub renal abdominal aortic aneurysm with thrombosis and fissuring in order to discuss the diagnostic and management aspects of this association.

Study of the Variation in Total and Reducing Sugars Contents According to the Variety and According to the Position Where the Fruit (Mango) Was Harvested from Five Mango Varieties Exploited in Senegal

引用

Journal of Biosciences and Medicines 2020年第3期8卷 28-36页

作者： ba ibrahima Fofana Mouhamadou Diop Moussoukhoye Natural Products Laboratory (LPN) Department of Chemistry Faculty of Science and Technology Sheikh Anta Diop University of Dakar Dakar Senegal

In this study, the results show that total sugar contents depend on the variety and the position where the fruit (mango) has been harvested. This variation in total sugar contents is observed according to the following varieties: the Bk (Boukodiekhal) variety (bottom position 45 mg/100 mL) then Bk (intermediate and bottom position 40 mg/100 mL) and with the Dr (Diourou) variety the content according to the intermediate position is 63 mg/100 mL while the content according to its bottom position is 56 mg/100 mL. The same is observed for variety Knt (Kent). For the variety factor, we see that the Dr and Sl (Sierra Leone) varieties are the richest in total sugars. Compared to the variation in reducing sugar content, the effect of position is less pronounced. Nevertheless, the statistical results show that the contents vary according to the varieties. There is a very significant variation in reducing sugar content between certain varieties. The variety Kt (Keitt) (45 mg/100 mL) is the richest in reducing sugars but compared to the lower position of the variety Bk, they are statistically identical. Variety Knt remains the poorest in reducing sugars 20 mg/ 100 mL.
