Epidemiology of Sudden Cardiac Death: Necropsic Studies at Aristide Le Dantec Hospital

Introduction: Sudden cardiac death (SCD) remains a major public health issue. In Senegal, there is a lack of data on this phenomenon; this underlies the relevance of this study whose objective is to study the epidemiological profile of victims experiencing unrecovered sudden cardiac arrest at Aristide LE DANTEC Hospital. Patients and Methods: This is a transverse study with retrospective data collection from January 1, 2016 to January 31, 2017. Included, in the study were all victims of sudden cardiac death in Dakar who had a necropsy in the morgues of Aristide Le Dantec Hospital. Results: We recorded 69 cases of sudden death of cardiovascular origin from 169 forensic autopsy reports, or 40.8% of autopsies. The average age was 44 years with a male predominance in 76.81%. The large majority of death occurred at home (26%), without witnesses (48%) and at rest (36%). Two cases of sudden death, or 3%, occurred at exertion. These deaths were recorded in 16% of cases in the middle of the day. The highest death rate was recorded during the month of December (15.9%). Malaise was the predominant symptom (13%) followed by emotional stress (6%). The existence of a history could only be clarified in 4% of cases. The electrocardiogram was only performed in 1 case. At necropsy, ischemic heart disease was the leading disease (46%), 26% of which was due to myocardial infarction, followed by hypertrophic cardiomyopathy (16%) and mixed cardiomyopathy (13%). Tamponade, dilated cardiomyopathy and aortic dissection were found in 9%, 6% and 4% of cases, respectively. Conclusion: Sudden cardiac death is a major public health problem. In the Senegalese population, victims of unrecovered SCD are relatively young with a predominance of men. Coronary artery disease is the most frequently implicated pathology. Faced with this observation, a national program for the integrated control of cardiovascular risk factors is necessary.

Outcomes of radical prostatectomy in patients with prostate cancer at the Aristide Le Dantec University Hospital

Le but était d´évaluer les résultats carcinologiques de la prostatectomie radicale. Il s´agissait d´une étude rétrospective monocentrique au service d´urologie-andrologie de l´Hôpital Aristide Le Dantec de Dakar du 1er juin 2010 au 31 mai 2016. Nous avons colligé 60 cas de prostatectomie radicale par voie rétropubienne associée à un curage ganglionnaire ilio-obturateur. Après la prostatectomie radicale (PR), le taux d’antigène prostatique spécifique (PSA) était indétectable (<0,1 ng/ml) chez 20 patients (33,3%). Onze malades (18,3%) qui avaient une récidive biochimique, ont une hormonothérapie complémentaire. Une réponse a été obtenue après instauration du traitement avec un taux de PSA total redevenu indétectable après un suivi de 8 mois. La durée moyenne de la survie globale était de 17,5 mois avec une médiane de 9,49. Le taux de survie globale cumulé à 1 an, 3 ans et 4 ans étaient respectivement de 42,4, 13,6 et 6,8%. La durée moyenne de la survie sans récidive était de 17,3 mois avec une médiane de survie sans récidive biochimique qui était de onze (11) mois. La durée moyenne de la survie spécifique était de 8,1 mois avec une médiane de 3 mois. Les marges de résection étaient positives chez sept (7) patients soit un taux de 11,6%. Quatre(4) patients avaient un envahissement ganglionnaire. La prostatectomie radicale indiquée dans quelques cas dans notre pratique, est une méthode thérapeutique efficiente avec de bons résultats carcinologiques.

Coronary Angiography: Indications, Results and Cost-Effectiveness in the Diagnosis of Stable Angina Pectoris in Two Hospitals in Senegal

Background: The current gold standard for the diagnosis of stable coronary artery disease (CAD) is invasive coronary angiography. But a large proportion of patients undergoing coronary angiography don’t have obstructive coronary artery disease. Objective: The aim of the present study was to evaluate the diagnostic performance of invasive coronary angiography for patients without known coronary artery disease presenting with stable chest pain syndrome at two hospitals structures in Senegal. Method: We conducted a prospective, descriptive, and analytical study from March 1, 2019, to December 31, 2020 in the Cardiology Departments of General Hospital Idrissa Pouye (HOGIP) and Aristide Le Dantec Hospital (HALD). During the study period a cohort of patients referred to angiography coronary for diagnostic CAD because of suspected stable angina were enrolled. Demographic characteristics, risk factors, symptoms, and noninvasive test results were correlated with the presence of obstructive coronary artery disease. Results: A total of 143 patients were included in our study with a median age of 60.91 ± 10.58 years; men were 96 (67.13%) and women 47 (32.87%). The prevalence of hypertension was 60.84%; diabetes was 34.27%; dyslipidemia was 32.17% and sedentary was 26.57% in our study population. Typical and atypical angina symptoms were present in 37.76% (n = 54) and 49.65% (n = 71) respectively, while 10.49% had dyspnea. Coronary angiography revealed 59 (41.26%) patients with no CAD as well as 27 (18.88%) with one-vessel; 28 (19.58%) with two-vessel, and 29 (20.28%) with three-vessel disease. Independent predictive factors for stable angina with the presence of obstructive lesion were: patient age (OR, 2.36; 95% CI, 1.05 - 5.29; p = 0.036); male gender (OR, 1.6; 95% CI, 0.72 - 3.57; p = 0.24); diabetes (OR, 2.14; 95% CI, 0.96 - 4.75; p = 0.06) and necrosis Q waves (4.75; CI, 0.98 - 23.09; p = 0.05). Conclusion: In our study, more than half of the patients (58.74%) referred for coronary angiography had a confirmed diagnosis. A better clinical and non-invasive assessment is needed to improve the efficiency of patient selection for coronary angiography.

Inventory of Radiation Protection in Hospitals of Level III in Senegal

The aim of this study was to evaluate the level of protection of employees who are exposed to radiation in a level III hospital establishment. It was a descriptive cross-sectional survey of six months’ duration, involving eight level III Hospitals (Aristide Le Dantec, Fann, Hoggy, Hear, Abass Ndao, Pikine, Touba, and Thies) in Senegal. Sixty-one of the one hundred questionnaires were recovered (overall response rate of 61%). The population of the study was mainly female (54.1%). The average age was 38.57 with extremes ranging from 23 to 65 years old. In the places where ionizing radiation sources are handled, only at the Aristide Le Dantec Hospital did we find a “competent person in radiation protection”. This explained the lack of a classification of employees and work areas. Forty out of sixty-one (73.77%) had no knowledge of the basic principles of radiation protection (justification, optimisation, dose limitation) and had not ever taken radiation holidays. For radiovigilance, exposure time limits to ionizing radiation concerned only 29/61 or 47.54% of the study population. The inverse square law of distance was known by only 40 workers, of whom 15 had no compliance. We found the presence of dosifilms in only 7/61 or 11.47% of the workers. On the other hand, the use of lead aprons was well established and concerned 57/61 workers, i.e., 93.44%. In sum, ionizing radiation causes adverse health effects. The absence of a good radiation protection culture in Senegal requires the presence of at least 4 to 5 competent persons in radiation protection for quality training of workers in radiobiology, radiopathology and radiation protection.

Epidemiological and Clinical Aspects of Autoimmune Dysthyroidism in Internal Medicine at Aristide Le Dantec Hospital

Introduction: Autoimmune thyroiditis is relatively common in medicine. However, comprehensive studies are few in number, especially in Africa and particularly in Senegal. The aim of this study was therefore to determine the epidemiological, clinical, profile of Autoimmune Thyroid Diseases (OITD). Materials and Methods: This was a retrospective descriptive study from 2016 to 2019 of the records of patients who consulted or were hospitalised for autoimmune dysthyroidism in the internal medicine department of the Aristide Le Dantec Hospital. During this period, 1227 new consultations were recorded; they concerned three specialized consultations including endocrinology. The autoimmune origin was confirmed in 159 patients, i.e. in 45.69% of cases the AIDM then 12.96% of all consultations. The autoimmune origin was established on clinical, biological and immunological grounds. The data were collected from the medical records of the patients and recorded on a pre-established individual survey sheet taking into account the objectives of the study. The data collected was entered into the Sphinx V5 software on an established form. The analysis was carried out with the following software: Excel 2010 and Epi info 7.2. Results: Among this dysthyroidism, 159 patients had a confirmed autoimmune thyroid disease. On all new consultations, OITD represented 12.96% of internal medicine consultations. The sex ratio M/F was 0.18. The majority of our patients (57.86%) were aged between 25 and 44 years with extremes ranging from 11 to 63 years. In Graves’ disease, the notion of an irritative spine was found in 60.27% of cases. Signs of thyrotoxicosis were present in 92.7% of cases. There was a goiter in 81.1% of cases with a vascular character in 76.47% of cases. Anti-THR antibodies were positive in 96.15% of cases. Complications were noted in 9 patients (6.5%) such as cardiothyreosis in 8 patients (5.7%) and malignant orbitopathy noted in 1 patient (0.8%). In Hashimoto’s thyroiditis, signs of hypometabolism were evident in 87.50% of patients. Anti-TPO antibodies were positive in all patients. All patients had received thyroid hormone supplementation. Thyroid autoimmune disease was associated with other autoimmune diseases in 6.2% of cases. Conclusion: Autoimmune thyroiditis is common in our daily practice in Senegal; it is dominated by Grave’s disease. Hypothyroidism was the most common manifestation of Hashimoto’s thyroiditis. The inaccessibility of antithyroid antibody testing is an obstacle to the diagnosis and management of these conditions.

Portal Thrombosis: Clinical, Etiological and Therapeutic Aspects in the Hepato-Gastroenterology Department of the Aristide Le Dantec Hospital in Dakar (Senegal)

Background: Portal thrombosis (PT) is a rare pathology. Its prevalence is estimated at 1%. Its consequences depend on the acute or chronic nature, the extent of the clot and the etiology. In Sub-Saharan Africa, very few studies have been devoted to it. Patients and Method: The objective of our work was to determine the prevalence of PT and to describe its clinical and etiological presentation as well as its therapeutic management in the Hepato-gastroenterology department of the Aristide Le Dantec hospital in Dakar. This was a retrospective, longitudinal and descriptive study during the period from January 1, 2012, to December 31, 2018. It included all patients followed in ambulatory or inpatient, who presented a PT objectively determined by a medical imaging examination (ultrasound and/or CT scan). Age, gender, clinical and radiological aspects, proposed treatments and etiology of PT were collected. Results: We collected 71 observations. The prevalence of PT was 1.9%. The mean age of the patients was 41 years 15 and 75 years. A predominance of men was found with a sex ratio of 2.73. The clinical manifestations were dominated by abdominal pain (74.6%), ascites (35.7%) and gastrointestinal bleeding (25.4%). Imaging allowed the diagnosis to be made in 50 patients on ultrasound and 21 patients on abdominal CT scan. PT was acute in 5 patients and chronic in 66 patients. Thrombosis was complete in 71.4% of cases and extended to the spleno-mesaraic venous trunk and the superior mesenteric vein in 2.8% and 8.4% respectively. Etiological research found cirrhosis complicated by hepatocellular carcinoma in 67.6% of cases, cirrhosis with cruoric thrombosis in 21.1% of cases, a combined protein C and S deficiency in 1.4% of cases. No aetiology was objectified in 9.9% of cases. Treatment with beta-blockers was initiated in 32 patients. Anticoagulant treatment was performed in one patient. Evolutionarily, no recurrence of bleeding was noted. In the anticoagulated patient, PT remained stable; however, there was no portal vein recanalization. During follow-up, mortality was 74.6% and was related to the underlying pathology in all patients. Conclusion: PT has a prevalence of 1.9% in the Hepato-Gastroenterology Department of the Aristide Le Dantec Hospital in Dakar. The chronic form is very dominant and degenerated cirrhosis is the first etiology.

Identification of Candida Species Circulating in Dakar using Multiplex Nested PCR

Background: In most developing countries, laboratory identification of Fungi belonging to the genus Candida is often problematic. The germ test tube known as Blastese test, which is the most used has the limitation that it only differentiates the C. albicans complex from other Candida complexes. Not only it is important to know the involvement of other species in the occurrence of fungal infections, but also the difference in sensitivity to the azoles used in the treatment of these fungal infections makes it necessary to identify the Fungi at the species level. The objective of this study was to identify by multiplex nested PCR the Candida species isolated in the laboratory of Parasitology and Mycology of Aristide Le Dantec Hospital, Senegal. Methodology: Candida isolates were obtained from patients who were admitted to the laboratory of Parasitology and Mycology with suspected fungal infections. After identification by conventional methods, isolates were preserved in a storage medium and kept at -20°C. Species identification was performed by nested PCR. Results: A total of 42 yeast isolates were collected after culture on Sabouraud medium, among which 10 (24%) from vaginal swabs and 32 (76%) from patients suffering from superficial mycoses (skin and nails). C. albicans represented 68% and nonCandida albicans (NAC) species 32%. The distribution of the NAC species was as follows: C. parapsilosis (group I and II) 17% (8), C. tropicalis 8.5% (4), C. kefyr 4.25% (2) and C. lusitaniae 2.15% (1). Mixed infection with two species represented 17.39% of the isolates. Conclusion: This study shows that other Candida species are common in Dakar, although their identification is not routinely performed in most laboratories. Thus, it is necessary to improve the technical facilities in these diagnostic laboratories.

Impact of the Covid-19 Pandemic on the Prolongation of the Management of Myocardial Infarctions Seen Late: A Cross-Sectional Study of 25 Cases Collected in the Cardiology Department of the Aristide Le Dantec Hospital in Dakar (Senegal)

Background: Timely management determines the prognosis of patients admitted for acute coronary syndrome with persistent ST-segment elevation (STEMI). Coronavirus COVID-19 appeared in China, in Wuhan in December 2019, which has spread at a lightning speed across the planet earth, becoming a pandemic. Senegal, as well as countries around the world, has also been affected by this pandemic, which has had a strong impact on all its sectors of activity, particularly the health system. The objective of this study was to identify and evaluate the factors that increase the time required to treat myocardial infarctions, received late at H?pital Aristide le Dantec and to assess the impact of the Covid-19 pandemic on these delays. Results: A total of 25 patients were included: 17 patients in pre-pandemic period and 8 patients in pandemic period. The predominance was male with a sex ratio of 2.5. The mean age was 59.20 years. Hypertension was the leading risk factor with a prevalence of 60% followed by sedentary lifestyle (48%). Typical chest pain was the most frequent clinical symptom found on admission (80%) followed by nausea and vomiting (40%). The first medical contact took place in a hospital in most patients (44%) and was made by a general practitioner (64%). The majority of patients (76%) were referred to the cardiology department. The personal car was the most frequently used means of transportation for our patients (60%). The average distance by car between the place of occurrence and the hospital was 22.6 km with extremes of 3.30 and 36 km. The average travel time from the place of occurrence to the cardiology department was 43 min 30 s with extremes of 11 and 57 min. When comparing the results according to the COVID-19 pandemic, a decrease in the number of incident cases is noted. Before the pandemic, a consultation in multiple units was noted in the majority of cases (41%) before admission. During COVID-19, the majority of patients (62.5%) had consulted only one site. The average time from pain to first medical contact was 06 h 30 min before the COVID-19 pandemic and 42 h06 min during the COVID-19 pandemic. The mean time to electrocardiogram recording was 14 h 30 min before the Covid-19 pandemic and 27 h 22 min during the Covid-19 pandemic. Conclusion: There are significant delays in the management of STEMI patients. They are attributable to both the patients and the system. The main factors of system delay found in our study were the delay in ECG recording, its interpretation, and the organization of transfer via a medical ambulance. The Covid-19 disease has globally aggravated these delays that were already present before the pandemic. Consequent measures must be taken to reduce these delays that determine the vital prognosis of STEMI patients.

Epidemiological and Cytological Profile of Breast Masses with Satellite Lymphadenopathies: About 422 Cases, Collected in Dakar, Senegal

Introduction: Breast masses with satellite adenopathies are a frequent reason for consultation, of various etiologies. Breast cancer, a major public health problem, remains the main obsession of the practitioner. Goals: Describe the epidemiological and morphological profile of mammary masses with satellite adenopathies, and determine the prevalence of breast cancer in this context. Patients and Methodology: A retrospective, descriptive, and analytical study from January 2012 to December 2016, based on the reports of patients who presented a breast mass associated with lymphadenopathy and cytological examination, in the laboratory of Pathological anatomy and cytology of Aristide le Dantec University Hospital. Results: We counted 422 patients, of whom 98.8% were women. The study population was predominantly urban (53.6%). The average age was 38.5 years with extremes of 10 and 81 years. The consultation period was an average of 17 months. Lesions in favor of breast carcinoma accounted for 55.7% of cases and lymph node involvement was observed in 46.7% of cases. Inflammatory benign lesions (10.9%) were dominated by mastitis (42 cases or 9.9%). Noninflammatory benign lesions (29.1%) were predominantly epithelial and epithelio-conjunctive hyperplasias (20.8%) Conclusion: Breast carcinoma constituted more than half of the breast mass with satellite lymphadenopathy causes, in the laboratory of Pathological anatomy and cytology of the University Hospital Aristide le Dantec.

Peripheral Arterial Disease among Patient Undergoing Maintenance Hemodialysis in Dakar (Senegal)

Background: Peripheral arterial disease (PAD) is common in patients with chronic kidney disease (CKD). It is a surrogate marker of generalized atherosclerosis. In sub-Saharan Africa, PAD remains understudied in CKD. Ankle-brachial index (ABI) is a non-invasive and cost-effective tool to diagnose PAD. Objectives: Our aim was to determine the prevalence and associated risk factors for PAD in hemodialysis patients. Patients and Methods: We conducted a cross-sectional study from July 1 to December 31, 2012 in the department of Nephrology of the University Hospital Aristide le Dantec of Dakar. All consenting patients, aged above 18 years, on hemodialysis for at least 6 months were included. ABI measurements were performed using a handled pulse doppler. PAD was defined as an ABI of <0.9 or the history of surgical revascularization and/or amputation due to vascular disease. The patients were divided into two groups according to the presence or not of PAD. Standard blood tests and anthropometrical parameters were recorded. Results: A total of 53 patients with a mean age of 49.15 ± 15.18 were included. The sex ratio was 0.70. Hypertension (83.01%), low HDL-cholesterol (26.41%) and cigarette smoking (20.75%) were the main cardiovascular risk factors. Prevalence of PAD was 47.16%. Among patients with PAD, 52% had no suggestive symptoms. Lower pre-dialysis (p = 0.0384) and post-dialysis (p = 0.0447) diastolic blood pressure (BP) were significantly associated with PAD. The conventional risk factors (tobacco consumption, diabetes, alcohol consumption, dyslipidemia, hypertension, age), iPTH and CRP levels were not correlated with PAD. Conclusion: PAD is common among patients undergoing maintenance hemodialysis in Senegal. Early diagnosis and management of PAD should be routinely performed in CKD patients.

Road traffic injuries among children in Dakar, Senegal

Background: Road traffic injuries (RTI) are a major public health problem and contribute significantly to the global burden. The aim of this study was to assess the frequency of RTIs in children and to determine their socio-demographic and lesional characteristics.Patients and methods: This was a retrospective and descriptive study over a two-year period from January 2015 to December 2016 conducted at the Department of Paediatric Surgery at the Aristide Le Dantec Hospital in Dakar. Included were all children under the age of 16 victims of a RTI. We studied various parameters relating to the victims (sex, age, education) and the accident (location andtime of occurrence of the accident, circumstances and mechanism, duration of admission to the emergency unit, localization and type of lesion). The data was entered and processed using Microsoft Office Word and Excel 2010 software.Results:Among the 425 cases received, 62.6% were boys and 37.4% girls. The average age of the children was 7.7 years. RTIs occurred mainly in pedestrian (63.8%) who wanted to cross the road. There were more accidents in the city-center area (64.9%) and during afternoons (61%). Lesions of the soft parts (wounds, contusion and decay) were predominated (89.6%) followed by fractures. Theupper limbs were the main locations of trauma.Conclusion: RTIs are common among children in Dakar. Boys crossing roads are the largest number of victims. Soft tissue trauma predominates and is mainly found on the thoracic limbs.

Effect of Prednicarbate On the Hyper Proliferation of the Granulation Tissue of Traumatic Wounds During Directed Healing: A Prospective Observational Study

Background: The directed scarring of traumatic wounds in a surgical department often encounters drifts. During the proliferation phase, the granulation tissue can become excessive, blocking re-epithelialization and dooming a skin graft. To cope with this, healthcare teams often use topical corticosteroids such as Prednicarbate which is a nonhalogenated corticosteroid which does not pass into the systemic circulation. Purpose: The aim of this study is to describe the in vivo effect of Prednicarbate on the hyper proliferation of granulation tissue in trauma wounds and burns during directed scarring. Methods: A prospective observational study was carried out on patients admitted consecutively to the Orthopaedic and Trauma Surgery Department of Aristide le Dantec Hospital in Dakar. The application of 0.25% prednicarbate was twice daily on the hyperprofiltration areas of the wound bed of consenting patients. Demographic, clinical, therapeutic data and changes in granulation tissue were collected. Results: 12 patients participated with an average age 41.5 ± 18.94 years and a female to male sex ratio of 3/1. Domestic accidents were the most common wound occurrence in 7 cases. After at least 3 applications, the modifications observed were as follows: the proportion of hyper-budding surface was reduced by 3% on average. In 8 cases, the bed turned pink, with a texture changing from smooth to granite in 10 cases. A regression of the edema of the bed was observed in all the cases and the level of the bed of the wound which initially known epidermal, became epidermal in 10 cases. In 10 cases, the start of epidermal migration was observed from the skin edges. In 9 cases, or 75% of cases, it took just 1 tube to see a reduction in granulation tissue. Conclusion: Prednicarbate is a non-halogenated corticosteroid which is of interest in reducing the excessive proliferation of granulation tissue in traumatic wounds. By normalizing the level of granulation tissue, it promotes epidermal migration and the epithelialization phase.

A twenty-eight-year laboratory-based retrospective trend analysis of malaria in Dakar, Senegal.

IntroductionHealth facility-based records offer a rich source of information to understand trends and changes in malaria cases over time. This study is aimed at determining the changes in malaria occurrence over the last 28 years, from 1989 to 2016 in Dakar, Senegal.MethodsLaboratory suspected and confirmed malaria records from 1989 to 2016 were reviewed from the laboratory registers of the Laboratory of Parasitology and Mycology of Aristide Le Dantec Hospital. Interrupted time series (ITS) analysis was used to estimate the changes by comparing malaria cases post-intervention (2006–2016) with that of the pre-intervention (1989–2005) period.ResultsA total of 5,876 laboratory confirmed malaria cases were reported out of 29,852 tested cases, with total slide positivity rate (SPR) of 19.7%. Malaria case counts exhibited a fluctuating trend with major peaks occurring in the years 1995 and 2003 with SPR of 42.3% and 42.5%, respectively. Overall, a remarkable decline in the total number of laboratory confirmed malaria cases was observed over the last 28 years. P. falciparum was almost the only reported species, accounting for 99.98% of cases. The highest SPR was observed in the age group of under five years during the pre-intervention period while this shifted to the age group of 6–15 years old for the subsequent years. Two major malaria peak seasons were observed: one in September during the pre-intervention period and the other in November for the post-intervention period. The ITS analysis showed a dramatic decline of 83.6% in SPR following the scale-up of interventions in 2006.ConclusionA remarkable decline in laboratory confirmed malaria cases in Dakar over 28 years was observed. The period of rapid decline in malaria SPR coincided with the scale-up in interventions beginning in 2006 with the introduction of ACTs, followed by the widespread introduction in 2008 of bed nets treated with insecticides. Robust surveillance data should be maintained in the context of malaria elimination efforts.

Sudden death in Dakar

Sudden adult death is an instantaneous or rapid death of natural, unexpected or unexpected origin. As a public health issue, the global incidence of sudden death would be 20100 per 100,000 population.The main objective of our study was to assess the incidence of sudden death in Dakar. The specific objectives were to establish the epidemiological profile of sudden death, identify the circumstances of its occurrence and the medical and surgical causes, and identify the factors associated with sudden deaths from cardiovascular causes.It is an observational, descriptive, retrospective study covering a period of 5 years, from January 1, 2014 to December 31, 2018. Included in the study were all records of adults (18 years of age and over) who died suddenly, in a health facility or outside it and were autopsied in the morgues of Aristide le Dantec Hospital (HALD) and Idrissa Pouye General Hospital (HOGIP).We found 1133 cases of sudden adult death, or 28 % of autopsies. The annual average was 226.6 cases. Our series consisted of 918 men and 215 women, for a sex ratio of 3.27. The sudden death of the adult was predominantly cardiovascular in origin with 561 cases or 49.5 %. The MI occurred on average at 51.95 years of age with 164 males (84.5 % of MIs) and 30 females (15.5 % of MIs). With regard to pulmonary causes, pulmonary tuberculosis was the leading cause of pulmonary origin with 66 cases or 26.2 %. For digestive causes, generalized acute peritonitis (GAP) was the most frequent cause with 29 cases (38.7 %).The prevention of sudden death is essentially based on cardiovascular disease treatment and prevention. The African context has to deal with weak health promotion, a failure of pre-hospital care and the daily difficulties of hospital care.

Geographical distribution of mycetoma cases in senegal over a period of 18years.

Mycetoma is a pathological process in which fungal or actinomycotic agents of exogenous origin produce grains. In the absence of data on the global burden, it is important to map mycetoma cases, which are useful to implement control strategies. The objective of this study was to map mycetoma cases diagnosed in Senegal over a period of eighteen years. The cases of mycetoma identified in the laboratory of Mycology at Aristide Le Dantec Hospital were extracted from the notebooks; information on the dates of collection, geographical origin and fungal agent identified was entered in Excel and analysed. Three hundred and thirty-seven cases of mycetoma were diagnosed from 1993 to 2016 at Aristide Le Dantec Hospital. Mapping shows that overall, the western zone presented the majority of cases 47% (120), followed, respectively, by the central zone 32% (80), the northern zone 18% (47) and the southern zone 2% (6). However, over the years, this distribution is different with a decrease in cases from the periods 1993-2000 and 2011-2016 of 19% in the western and a progressive increase of cases in northern and central zones of, respectively, 13% and 14%. In the 1990s, the cases were predominant in Dakar, Louga and Diourbel. During 2011-2016, Thies, Diourbel, Fouta and Louga presented more cases. The spatial distribution of mycetoma in Senegal changed over the years, most frequent in the west of the country, and during 1993 to 2000, mycetoma is now more common in the north.

Analysis of Cesarean Section Indications According to the Robson Classification in Surgical Maternities in Dakar, Senegal: About 9185 Cases

Background: The caesarean section rate remains relatively high in the surgical maternity hospitals in Dakar and the indications for scarred uterus are still high. The management of induced prematurity for maternal pathologies still poses real problems in Dakar. The aim of our study is to compare the Caesarean section rate in the different surgical facilities in Dakar. We used the ROBSON's classification to evaluate the indications for Caesarean section in surgical maternity hospitals in Dakar. Methods: This was a descriptive and analytical prospective study which took place from January 1^st to December 31^st 2019 in 10 surgical maternity hospitals in Dakar (University hospital Aristide Le Dantec, National Hospital Center of Pikine, Municipal Hospital Center Abass NDAO, Principal Hospital of Dakar, Youssou Mbargane DIOP Hospital in Rufisque, Ouakam Military Hospital, Grand Yoff General Hospital, Gaspard Kamara Health Center, Nabil Choucair Health Center, Roi Baudoin Hospital Center) and which included all patients who delivered by caesarean section. Indications for Caesarean section were classified according to ROBSON's 10 group classification. The parameters studied were age, frequency, indications for Caesarean section in these surgical maternity hospitals and, Apgar score at five minutes and, birth weight. Data collection was done through birth records and registers, on-call diaries and integrated into a database developed with Sphinx software. Statistical analysis was done using SPSS software. Results: During the period of the study we recorded 35287 deliveries with 9185 Caesarean sections, i.e. a frequency of 26%. The average age of the patients was 29 years. Indications for Caesarean section in Dakar surgical maternity hospitals were dominated by group 5 (28.4%) according to Robson's classification. Group 10 in Robson's classification was predominant in the maternity hospitals of University hospital Aristide Le Dantec (23.3%) and Municipal Hospital Center Abass NDAO (22.5%). Group 5 was found in the maternity units of the Gaspard Kamara Health Center (32.3%), Nabil Choucair Health Center (39%), Principal Hospital of Dakar (26.4%), Youssou Mbargane Hospital Diop Hospital in Rufisque (31.4%), Roi Baudoin Hospital Center (29.8%), Grand Yoff General Hospital (32%), Ouakam Military Hospital (34.2%), and, National Hospital Center of Pikine (27.9%). 4 facilities had a caesarean section rate higher than 30% (University hospital Aristide Le Dantec 35.6%, Youssou Mbargane Diop Hospital in Rufisque 32.03%, Municipal Hospital Center Abass Ndao 32.01% and, National Hospital Center of Pikine 30.45%). The average birth weight of new-borns was 2943 grams, with an average Apgar score of 8 at the fifth minute. The post-op care was simple. Conclusion: The caesarean section rate remains relatively high in the surgical maternity hospitals in Dakar and the indications for scarred uterus are still high.

Immunosuppressive Treatment of Connective Tissue Disease and Occurrence of Tuberculosis

Introduction: The occurrence of tuberculosis (TB) during the follow-up of Connective tissue diseases (CTD) is a particular situation often posing real diagnostic problems. This is an association described in the literature. Patients and methods: We conducted a retrospective and descriptive study at the internal medicine department of Aristide Le Dantec Hospital. The purpose of this study was to determine the treatment that patients followed for CTD and suffering from TB took before the occurrence of this one. Results: During a study period of 11 years and 6 months, 21 cases of TB were diagnosed in 602 cases of CTD (0.03%). The predominance was female with a sex ratio (H/F) of 0.6. The median age was 42 years old. The majority of cases originated from the Dakar region (13 patients or 61.9%) and 85.7% had previous follow-up exclusively in modern medicine and 21 cases (95%) received the CTD’s treatment. This consisted of prednisone (90.5%) combined with methotrexate (52.4%), azathioprine (23.8%) or cyclophosphamide (19.4%). The respective medians doses of these drugs were 12.5 mg per day for prednisone, 13.5 mg per week for methotrexate and 100 mg per day for azathioprine. The median duration of patient follow-up was 36 months. The cumulative dose of prednisone during this period was 23.6 g and that of methotrexate 2.25 g. CTD were dominated by rheumatoid arthritis (RA) (57.1%), and systemic lupus (19%). Isolated cases of systemic scleroderma, primary Sjögren, SHARP syndrom, mixed connective tissue disease, and multiple autoimmune syndrom were noted. TB was localized in 95% of cases, readily bilateral and poorly disseminated. The respective medians diagnostic delays for systemic disease and TB were 21 months and 5 months. Tuberculin intradermal reaction was performed in 16 cases and was positive in 9 cases, sputum bacilli was performed in 19 cases and was positive in 15 cases. Conclusion: The association of TB and CTD was characterized by its rarity, its poorly disseminated character and its frequency on RA field.

Delays in the management of acute coronary syndroms with ST segment elevation and extending factors: Prospective study about 50 cases in cardiology department of Aristide Le Dantec hospital.

Management of acute coronary syndromes with ST segment elevation (STEMI) is a race again time: time is myocardium». Treatment consist in reperfusion strategy by coronary intervention or thrombolysis. The main objective of this work was to evaluate the time delays of treatment and the extending factors during STEMI. It was a prospective, descriptive and analytic study on 6 months including all patients admitted for STEMI. We studied the time delays and the extending factors. We included 50 patients. The average age was 58,4 years and the sex ratio M/F was 2,5. Chest pain was typical for 39 patients. Mean time delay between pain onset and first medical contact was 12 h16 min. The first medical contact was a general physician for 33 patients and a cardiologist for 8 patients. The average time delay between the first medical contact and an electrocardiogram was 9 h57 min. The main factor of late diagnosis were unavailability of electrocardiograph and absence of prescription of an electrocardiogram. The average time delay between the diagnosis electrocardiogram and admission in cardiology department was 3 h02 min. The transport was the main extending factor. Aspirin and clopidogrel were used respectively for 17 and 10 patients. Among the patients admitted directly in cardiology, the average time delay for a diagnostic electrocardiogram was 30 min. Thrombolysis was performed in 17 patients within an average delay of 2 h11 min. A rupture of streptokinase was the most common extending factor. Twenty-three patients underwent percutaneous coronary intervention with a main time delay between diagnostic electrocardiogram and cath lab of 2 h42 min. The unavailability of medical team was the first extending factor. Factors related to long delay in admission and care are a proof of lack of codified management of STEMI. It is necessary to develop the prehospital emergency medicine, educate population and medical staff.
