Pan African Medical Journal , 2010,
Abstract: Les données relatives à l’infarctus du myocarde chez le jeune adulte sont rares en Afrique noir. Nous rapportons une série rétrospective de 14 cas d’infarctus du myocarde chez l’adulte jeune noir africain. Pour analyser les caractéristiques épidémiologiques, cliniques, électriques, échographiques, biologiques, thérapeutiques et évolutives de l’infarctus aigu du myocarde chez le jeune adulte nous avons étudié de manière rétrospective les dossiers médicaux d’une série consécutive des patients admis entre Janvier 2003 et Décembre 2008 pour prise en charge d’infarctus aigu du myocarde. Quatre-vingt quatre (84) cas d’infarctus du myocarde ont été pris en charge durant la période d’étude ,14 patients (16,6%) avaient un age inférieur ou égal à 40 ans. L’age moyen était de 34 +ou-5ans (extrêmes 27ans et 40 ans). Les facteurs de risque cardio-vasculaire étaient dominés par le sexe masculin (n=11), la dyslipidémie (n=7) et le tabagisme par cigarette (n=6). La contraception orale était absente chez le 1/3 des patients. Le délai moyen d’admission était tardif (15 plus ou moins 4 heures). L’IDM était antérieur dans la moitié des cas. L’acide acétylsalicylique, les inhibiteurs de l’enzyme de conversion Les bétabloquants et les statines étaient les médicaments les plus prescrits. La thrombolyse et l’angioplastie étaient respectivement réalisées chez 3 patients et 0 patient. 4 cas d’insuffisance cardiaque, 2 cas de bloc atrio-ventriculaire complet et 1 cas de décès étaient les principales complications. L’infarctus du myocarde concerne également le sujet jeune noir africain. Les facteurs de risque sont essentiellement représentés par le sexe, la dyslipidémie, le tabagisme et la contraception orale.

Abstract: INTRODUCTION: La fibrillation atriale est le trouble du rythme cardiaque soutenu le plus fréquent. Les objectifs de ce travail étaient d’étudier la fréquence, les facteurs étiologiques, l’évolution et le traitement de la fibrillation atriale dans un service de cardiologie de Dakar au Sénégal. METHODES: Il s’agit d’une étude rétrospective réalisée sur cinq ans et portant sur l’analyse de 150 dossiers de patients hospitalisés pour une fibrillation atriale. RESULTATS: La fréquence de la fibrillation atriale était de 5,35 % et représentait 66% des troubles du rythme cardiaque avec une prédominance féminine (sex-ratio H/F = 0,45) et un age moyen de 57,06 ± 18,64 ans. L’origine de la fibrillation était valvulaire dans 36,7% des cas. Les complications thromboemboliques étaient plus fréquentes dans la fibrillation atriale non valvulaire (p=0,006), chez les sujets d’age > 50 ans (p=0,01) et en cas de dilatation de l’oreillette gauche (p=0,05). Une anticoagulation par anti-vitamine K était instaurée dans 62% des cas et un traitement de contr le de la fréquence cardiaque dans 87,33%. CONCLUSION: La fibrillation atriale est fréquente en milieu hospitalier africain et concerne des sujets relativement jeunes. L’hypertension artérielle et les valvulopathies rhumatismales sont les principaux facteurs étiologiques. Le traitement reste essentiellement médicamenteux par contr le de la fréquence cardiaque.

Abstract: Background: The true scale of renal insufficiency (RI) in Sub-Saharan Africa remains unknown due to the lack of national registries. The aim of this study is to describe the epidemiological characteristics of renal insufficiency in urban areas in Saint Louis of Senegal. Materials and Methods: It is an observational, cross-sectional and descriptive study. The study was conducted during 27 days starting from 3 to 30 May 2010. All senegalese residents of Saint Louis (older than 15 years at the time of the study) in whom creatinine clearance was performed were included in the study. The sampling method used was a systematic random sampling, stratified cluster. The survey was designed by an expert comitee based on STEPS survey of the World Health Organization. RI was defined as a glomerular filtration rate (GFR) < 60 ml/min/1.73m2. Results: Among 1424 people initially selected a final selection of 1416 was made. The sex ratio was 0.45. The mean age was 43.4 ± 17.8 years. The overall prevalence of renal insufficiency according to MDRD (Modification of diet in renal disease) formula was 181 cases or 12.7%. The mean age of the people with renal insufficiency was 47.6 ± 17.4 years. Renal insufficiency was correlated to height blood pressure (p = 0.01) and Physical inactivity (p = 0.0001). The prevalence of renal insufficiency was higher in diabetics (71.4%) and obese people (66.6%) than in non-diabetics (64.9%) and non-obese people (56.5%), although the difference was not statistically significant. Dyslipidemia and smoking were not correlated to the risk of occurrence of IR. Conclusions: This study reports the increasing magnitude of RI and its risk factors in the city of Saint Louis in Senegal. It is imperative to establish à national prevention strategies to avoid the dizzying growth of this scourge.

Abstract: Introduction: In Senegal, the frequency of diabetes mellitus is estimated at 3.2% and its management by the general patrician (gp) is dissatisfied. The objective was to evaluate the decentralized monitoring of diabetes mellitus and other cardiovascular risk factors by a trained general practician. Patients and methods: It was a retrospective, descriptive study conducted from June 1, 2013 to 31 May, 2015 in Dakar, where included the files of subjects with diabetes mellitus regularly followed. The data collected were epidemiological, diagnostic and therapeutic. Results: It was of 125 diabetics patients with a mean age of 56.4 years old. At the inclusion, their diabetes had a mean duration of 6.3 years and a mean average HbA1c of 10.4%. The complications were a neuropathy in 58 cases (46.4%), an arteritis in 46 cases (36.8%), a nephropathy in 16 cases (12.8%) and a retinopathy in 28 cases (22.4%). Other cardiovascular risk factors were an arterial hypertension in 74 cases (59.2%), smoking in 11 cases (8.8%), kidney disease in 16 cases (12.8%), and LDL-cholesterol > 1.6 g/l in 39 cases (31.2%). In total, 87 patients (69.6%) were at high cardiovascular risk and among them, 81.6% had LDL-cholesterol > 1g/l. At inclusion, anti-diabetic treatment was oral mono-therapy in 53 cases (42.4%), an insulin therapy in 49 cases (39.2%). After 12 month of follow-up, the dual therapy anti-diabetic was increased from 13.6% to 34.4%. The others associated drugs were anti-hypertensives in 72 cases (57.6%), statins in 29 cases (23.2%) and anti-platelet agent in 46 cases (36.8%). Only 31.2% of the patients with nephropathy were under the renin angiotensin system blockers. Statins and the anti-platelet agents were prescribed respectively at 25.2% and 47.1% of the 87 patients at high cardiovascular risk. During follow-up, the target HbA1c < 7% was reached in 76 cases (60.8%). Conclusion: our study shows the importance and the interest of a trained general practician for the management of non-communicable diseases. However, it would be necessary to strengthen training in the care of other cardiovascular risk factors.

Open Journal of Internal Medicine (OJIM) , 2017, DOI: 10.4236/ojim.2017.73007
Abstract: Introduction: The resting electrocardiogram is generally called upon in the evaluation of cardiovascular risk in diabetics. Thus we proposed in this work to evaluate electrocardiographic changes in patients with type 2 diabetes. Methods: This was a cross-sectional and descriptive observation that took place from 1 January 2014 to 1 October 2014 in the Internal Medicine/Endocrinology Departments of Pikine National Hospital and Cardiology National Hospital of Grand-Yoff. Results: One hundred (100) patients consisted of 43 male and 57 female diabetics. The sex ration male/female ratio was 0.7. The average age was 58.3 years. Men were twice as likely to be active as women. Rhythm disorders were noted in 20% of patients, 13% of whom were women. Right atrial hypertrophy was found in 11% of patients and left hypertrophy in both men and women (25%). Wolf-Parkinson White syndrome was present in 2% of patients. A complete right bundle block was present in 11% of patients. Primary repolarization disorders were noted in 17% of patients and secondary in 18% of patients, postero-diaphragmatic necrosis in 14% of patients, real posterior necrosis in 2% of patients, extensive anterior necrosis in 15% of patients. The QT interval was lengthened in 21% of patients including 14 women. Left ventricular hypertrophy was present in 33% of patients and right ventricular hypertrophy was found in 10% of patients. The bivariate analysis showed that electrocardiographic abnormalities were more correlated with the association of certain risk factors such as hypertension and dyslipidemia, the feminine gender, but also the poor glycemic balance. On the other hand, physical activity and treatment had a protective effect. Conclusion: The ECG is certainly insufficient for an exhaustive exploration of the heart of the diabetic patient, but still very useful in our conditions of exercise to improve the care of our patients.

Abstract: Introduction: The practice of minimally invasive surgery in Senegal occupies more and more of a preponderant place in fields that previously did not allow it. Thus in our practice in gynecology we are witnessing an explosion of these operative indications especially for benign adnexal pathology. Patients and Method: The objective of this study was to evaluate the evolution of laparoscopic practice in terms of frequency, indication of duration and operative complications. For this reason, we have collected all the laparoscopic procedures carried out at the Gynecology and Obstetrics Department of the Pikine National Hospital since January 1st, 2012 over a period of 60 months. Endoscopic surgery accounted for 20.1% of all gynecological and breast procedures. There were 195 cases (14.9%) of laparoscopic surgery and 69 cases (5.2%) of operative hysteroscopy. The average age of our patients was 34 years with extremes of 15 and 67 years. The intervention was motivated by the exploration or management of infertility in 101 cases, or 57.1% of patients. Laparoscopy remained exploratory in 15.3% of cases (279 patients) with 55 cases of ovarian tumors presumed to be benign. The mean duration of diagnostic laparoscopy was 39 min with extremes of 20 to 150 min; while that of operative laparoscopy was 59 min with extremes of 20 to 250 min. It was noted that 4 cases of laparoconversion

Abstract: Despite the growing interest in athlete’s right ventricle and various work carried out, many uncertainties are remaining. The interest of this work resides in the determination of the particularity in right heart of the black athlete subject. We conducted a prospective study from August to October 2016 in the cardiology department of Aristide Le Dantec University Hospital in Dakar. The included patients were divided according to the sporting practice as enduring, resistant and non-athletes. The parameters studied were electrocardiographic (atrial or ventricular hypertrophies), echocardiographic: dimensions of the right cavities, systolic and diastolic functions of the right ventricle. We included 58 subjects: 38 athletes including 28 endurance and 10 resistance and 20 non-athletes. The average age of the endurance athletes was 21.9 ± 3, 75 years, 26.30 ± 4.64 in resistance ones and 24.10 ± 1.89 in the non-athletic group. Two cases of first-degree atrioventricular block were recorded in athletes. On the echocardiographic point, the atrium surfaces, as well as the transverse diameter, were greater in athletes, especially in the endurance group. The mean diameters of the admission chamber and those of the right ventricular flush chamber were larger in the group of endurance athletes. It was the same for the annular and sagittal basal mean diameters of the RV as well as the RV/LV ratio. The anterior wall of the right ventricle was larger in athletes compared to non-athletes. The vena cava was greater in athletes, the pulmonary arterial pressure higher in resistance ones.

Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.33034
Abstract: The present paper presents a new method to solve fluid structure interaction problem. Our computational method is based on controllability approach. Given a target structural displacement we will find a control steering the displacement of the structure u to . We need to define a payoff functional (J): where u solves the structure equation for the control and is a fixed value. Our aim is to find a control which minimizes the payoff criterion. And therefore we find u the beam displacement, v the velocity of the fluid and p the pressure of the fluid.

Abstract: Objective: To assess a training approach in Emergency Obstetric and Neonatal Care (EmONC) to strengthen skills of healthcare providers and reduce maternal mortality. Materials and methods: The approach was based on the skills training using the so-called “humanist” method and “life saving skills”. Simulated practice took place in the classroom through thirteen clinical stations summarizing the clinical skills on EmONC. The evaluation was done in all phases and the results were recorded in a database to document the progress of each learner. Results: We trained 432 providers in 10 months. The increase in technical achievements of each participant was documented through a database. The combination of training based on the model “learning by doing” has ensured learning and mastering all EmONC skills particularly postpartum haemorrhage management and reduced missed learning opportunities. Conclusion: The impact of training on postpartum haemorrhage management and maternal mortality is a major challenge in terms of prospects.

Abstract: Introduction: In Senegal, surveys have revealed areas of high endemicity of?Schistosomiasis including the town of Richard Toll. We undertook this study?to determine the echocardiocardiographic characteristics of school-agechildren in endemic bilharziasis. Methodology: We performed a descriptive cross-sectional study in Richard Toll and Dakar in school-age children. Results: A total of 250 children were included. There was male?predominance, age between 4 and 16 (10 years old ± 2.77). Hematuria was reported in 69.6% of cases in endemic areas. Positive testing for Schistoma hæmatobium was found exclusively in Richard-Toll at 33.5%. The diastolic, systolic, basal and median left ventricle dimensions were larger in Richard Toll’s population compared to Dakar. It was the same for the right chambers dimensions. The average pulmonary systolic arterial pressure was greater in Richard-Toll: 26.38 ± 3.16 mmHg versus 21.82 ± 1.73 mmHg in Dakar (p < 0.001). There was a correletion between pulmonary systolic artérial pressure and presence of hematuria, anemia and parasitological positivity. Conclusion: The heart of the school-aged child in endemic area is characterized by larger cavitary dimensions.
