[Acute heart failure with altered ejection fraction : Electrocardiographic signs with mortality at the Abidjan cardiology institute]. / Insuffisance cardiaque aiguë à fraction d'éjection altérée : signes électrocardiographiques associés à la mortalité à l'institut de cardiologie d'Abidjan.

INTRODUCTION: Heart failure with impaired ejection fraction (HFIEF) represents the end-stage of most cardiac diseases, and is responsible for a high mortality rate. In order to identify patients at risk, numerous clinical and paraclinical prognostic factors have been proposed. The electrocardiogram (ECG), easy to perform and inexpensive, retains a powerful role in the prognostic evaluation of heart failure patients. The aim was to evaluate ECG signs associated with mortality in a retrospective cohort of patients with ICFEA. METHODOLOGY: The study was observational and analytical based on retrospective data collected from patients benefiting from a primary hospitalization for ICFEA at the Abidjan Heart Institute from January 2018 to July 2020. RESULTS: Of the 370 patients included, 197 had died by August 1, 2020, representing an overall mortality of 53%. Mortality progressed gradually up to one year, then remained unchanged up to 30 months. In multivariate Cox regression including ECG variables only, the presence of intra-ventricular conduction disorders (OR: 1.80; 95% CI [1.01-3.25]), microvoltage (OR: 1.82; 95% CI [1.05-16]), and pathological Q waves (OR: 1.70; 95% CI [1.02-2.83]), were significantly associated with overall mortality. When ECG variables and clinical, paraclinical and therapeutic demographic variables were included, only the presence of pathological Q waves (OR:1.74; 95% CI [1.01-3.01]) persisted as a risk factor for mortality. Hypertension and treatment of heart failure, in particular ACEI/ARII, beta-blockers and ARM, were protective factors. The presence of Q waves was associated with a significant reduction in survival, based on curves obtained using the Kaplan-Meier model. CONCLUSION: ICFEA is responsible for high mortality, mainly in the year following the 1st hospitalization for cardiac decompensation. The presence of pathological Q waves is the only electrocardiographic sign that remains statistically associated with a poor prognosis, after adjustment.

[Characteristic and evolution of pacemaker complications in a Subsaharan Africa Heart Centre]. / Caractéristiques et évolution des complications de la stimulation cardiaque dans un centre de cardiologie de l'Afrique de Subsaharienne.

AIM OF THE STUDY: The working environment and the low rate of pacemaker insertions increase the risk of complications in sub-Saharan Africa. The objective of our work was to assess the impact of specific preventive measures on these complications over the long term. PATIENT AND METHODS: We conducted a retrospective study of all pacemaker implantations from June 2006 to June 2016 at the Abidjan Heart Institute. We evaluated the incidence of pacemaker complications, their risks factors and their impact on the overall prognosis of patients. RESULTS: Three hundred and two procedures were performed in 286 patients (49% male, mean age: 67±12 years), with a predominance of primary implantation (82.8%) of single-chamber ventricular pacemakers (66.6%). Twenty-five major complications (8.27%) and 14 minor (4.6%) occurred with a predominance of lead displacements (3.64%). The major complications were favored by the subclavian approach (P=0.018; OR=2.34; 95% CI [1.16-4.75]) and intraoperative incidents (P=0.02; OR=2.17; 95% CI [1.16-4.75]. The preventive measures taken made it possible to achieve a significant (P=0.017) and linear (P=0.009) reduction of these complications, with no effect the patients prognosis (Log-Rank=0.217; P=0.64). CONCLUSION: Quality cardiac stimulation is possible in Sub-Saharan Africa with preventive measures adapted to the environment.

[Indications and results of pulmonary resections in a developing country]. / Indications et résultats des exérèses pulmonaires dans un pays en développement.

INTRODUCTION: Indications for pulmonary excision are dominated by infectious pulmonary pathologies in developing countries. We conducted this study to describe the indications and results of pulmonary resections in the thoracic surgery department of the Mali hospital. PATIENTS AND METHODS: This is a retrospective and descriptive study from January 2012 to December 2019, carried out in the thoracic surgery department of the Mali hospital. It involved 76 patients who had a pulmonary resection. The variables studied were the epidemiological data, the operating indications, the therapeutic data and the prognosis. RESULTS: The mean age of the patients was 35.5 years. The sex ratio was 1.7. The average consultation time in thoracic surgery was 11.6 months with extremes of 7 days and 96 months. A history of pulmonary tuberculosis was noted in 46.1% of patients. The main indications for pulmonary resection were infectious parenchymal destruction in 64.5%, bullous dystrophy in 14.5%, bronchopulmonary cancer in 11.8% and thoracic trauma in 4% of the cases. The procedures performed were: a lobectomy (39.5%), atypical resection (36.8%), culminectomy (7.9%) and pneumonectomy (15.8%). Morbidity was dominated by thoracic empyema (9.2%) postoperative hemorrhage (5.2%), parietal suppuration (7.8%) and bronchopleural fistula (1.3%). The average length of hospital stay was 14.3 days. Mortality was 10.5%. There was a statistically significant correlation between pneumonectomy and deaths (P=0.01). CONCLUSION: Infectious lung destruction is the main indication for pulmonary resection in Mali. The consultation period is quite long. Morbidity and mortality remains high.

[Prescribing habits of physical activity by cardiac physicians in Côte d'Ivoire]. / Habitudes de prescription de l'activité physique par des médecins cardiologues en Côte d'Ivoire.

Regular physical activity (PA) has multiple health benefits that contribute to the prevention and management of many non-communicable diseases such as cardiovascular disease. However, a large proportion of the world's population is not active enough to benefit its health. Despite the potential of physicians to increase the level of PA practice in both primary and secondary prevention, there appears to be little intervention in this direction during medical consultations. What is the situation in Côte d'Ivoire? We conducted a prospective study that focused on the description and analysis of the practice of PA awareness and prescribing of Côte d'Ivoire cardiologist physicians and to examine the extent to which their socio-cultural characteristicsdemographics, their personal PA practices, barriers and needs influenced their PA prescribing in primary or secondary prevention settings. The results showed a high rate of overweight and obesity (64 %) and a low level of PA (40 %). We noted a high rate of locating (90 %) and advising AP (92 %). High blood pressure (98 %) and obesity (94 %) were the major conditions for which physicians prescribed PA. They were mainly about walking (94 %) and through oral counselling (80 %). Among the brakes identified were mainly the lack of knowledge about PA prescribing, lack of consultation time and lack of motivation of patients in 48 %, 44 % and 34 % of cases respectively. In terms of the needs expressed to promote the prescription of PA, it was mainly the personal conviction of the physician of the interest of prescribing an PA (80 %), of the organization of training on the prescription of PA (78 %) and completion of patient handouts (56 %).

Tetanus associated with road accidents in the infectious diseases department of Point G University Hospital, Bamako, Mali.

The aim of this study was to describe the epidemiological, clinical, and prognostic aspects of tetanus associated with road accidents and to make recommendations. This observational study collected retrospective clinical data over a 9-year period about adults admitted for trismus and/or generalized or localized paroxysm after a road accident. The study included 25 patients, accounting for 22.12 % of all tetanus cases. Men were massively overrepresented (sex-ratio M/F: 24/1). The median age was 34 ± 8 years. In all, vaccination status was unknown for 4 patients and known to be negative for 21. Immunoprophylaxis was nonexistent in all cases. The generalized clinical form was dominant (96 %). Severity reached level III for 12 % of patients. The points of entry included open leg fractures (4 cases), head wounds (2), mucocutaneous wounds (14), and muscle contusions (5). The mean time to referral for tetanus was 8 ± 7 days, and the median hospital stay 9.08 ± 11 days. Patients were mostly residents of urban (56 %) and suburban areas (28 %) [P = 0.04]. Two cases were complicated by severe malaria. The mortality rate was 60 %, and 52 % of the deaths occurred within the first 72 hours after hospitalization. It is essential to promote serum therapy and tetanus immunization for patients after road accidents. Increasing the awareness of traditional healers of these treatments deserves consideration.

[Coronary artery aneurysms probably due to Kawasaki's disease]. / Anévrismes coronaires chez un adulte jeune évocateurs d'une probable maladie de Kawasaki.

We report the case of a young adult admitted to the Abidjan Heart Institute for coronary angiography to explore unstable angina. Coronary angiography showed multiple aneurysms which suggested sequelae of misdiagnosed Kawasaki disease.

[Prevalence and characteristics of acute coronary syndromes in a sub-Saharan Africa population]. / Prévalence et caractéristiques des syndromes coronariens aigus dans une population d'Afrique subsaharienne.

AIM: To assess prevalence, characteristics and management of acute coronary syndromes in sub-Saharan Africa population. PATIENTS AND METHODS: Prospective survey from January, 2010 to December, 2013, carried out among patients aged 18 years old, admitted to intensive care unit of Abidjan Heart Institute for acute coronary syndrome (ACS). RESULTS: Four hundred and twenty-five (425) patients were enrolled in this study. Prevalence of ACS was 13.5%. Mean age was 55.4±11 years. Clinical presentation was predominantly ST-segment elevation myocardial infarction (STEMI) in 71.5% of subjects, non-ST-segment elevation acute coronary syndrome (NSTE-ACS) accounted for 28.5%. Two hundred and eighty patients (65.9%) were transferred by unsafe transportation. Among the 89 patients admitted within 12hours of the onset of symptoms, primary percutaneous coronary intervention was performed in 20 patients (22.5%), or 6.6% of STEMI as a whole. Twenty-five patients (8.2%) received fibrinolytic therapy with alteplase. In-hospital death rate was 10%. CONCLUSION: The prevalence of acute coronary syndromes is increasing in sub-Saharan Africa. Excessive delays of admission and limited technical facilities are the major difficulties of their management in our regions.

Rapid detection of Mycobacterium tuberculosis complex in sputum Samples using PURE TB-LAMP assay.

OBJECTIVE/BACKGROUND: Lack of rapid and accurate diagnostic testing is a critical obstacle to global tuberculosis (TB) control. Sensitivity of sputum smear microscopy (SSM) is not optimal; however, it remains the most prevalent tool for TB confirmation in poor countries. As a part of passive case finding of TB detection, this study was conducted to determine the clinical performance of PURE TB-LAMP assay using liquid culture medium as the gold standard. METHODS: Centre Antituberculeux de Yopougon is one of the 17 intermediate Tuberculosis centers in Côte d'Ivoire. A standardized questionnaire was submitted to patients with signs and symptoms consistent with tuberculosis by a trained caregiver. After obtaining signed consent forms, sputum samples were collected according to National TB Control Programme guidelines (spot-morning). SSM after Ziehl-Neelsen staining and TB-LAMP assay were blindly performed on the first sample. Samples transported to Institut Pasteur de Côte d'Ivoire were decontaminated according to the N-acetyl-L-Cystein method. In Mycobacteria Growth Indicator Tube (MGIT), 500mL of pellets were inoculated and incubated in the MGIT 960 system. MPT64 antigen was detected in positive cultures. RESULTS: Of the 500 patients enrolled, 469 (232men and 239 women) patients were included. The mean ages of men and women were 36.9 (15-86) and 37.3 (15-37.3) years, respectively. There were 56 (12.2%) HIV-infected patients, including 14 women. Clinical isolates of M. tuberculosis complex were detected for 157 (33.5%) patients. Compared with culturing, the overall sensitivity and specificity of SSM were 86% (95% confidence interval [CI]=81-91) and 96% (95% CI=94-98), respectively. The overall sensitivity and specificity for TB-LAMP was 92% (95% CI=0.88-0.96) and 94% (95% CI=0.91-0.97), respectively. Positive likelihood ratios for TB-LAMP and SSM were 15.3 and 21.5, respectively, and negative likelihood ratios for TB-LAMP and SSM were 0.09 and 0.15, respectively. Among the 469 patients, active tuberculosis was detected using TB-LAMP assay and SSM in 162 (34.5%) and 147 (31.3%) patients, respectively. CONCLUSION: For accurate diagnostic of pulmonary TB, TB-LAMP could be used as a tool of the first intention.

[Presumption of sleep apnea in a black African hypertensive population: Importance of the Epworth sleepiness scale in the diagnostic approach]. / Présomption d'apnées du sommeil dans une population d'hypertendus Noirs africains : intérêt de l'échelle de somnolence diurne d'Epworth dans l'approche diagnostique.

INTRODUCTION: Sleep apnea syndrome (SAS) is very little described in the hypertensive black African. PURPOSE: To screen sleep apnea syndrome using the rating scale of Epworth daytime sleepiness, and to investigate the determinant factors and to infer therapeutic consequences. METHOD: This is a retrospective and prospective study with descriptive and analytical purpose that focused on 200 hypertensive outpatients of the Cardiology Institute of Abidjan. The primary endpoint studied was the SAS. The diagnostic approach of SAS was performed using the rating scale of Epworth daytime sleepiness. RESULTS: The prevalence of sleep apnea was 45%. The average age of sleep apnea carriers was 56.1 years, with a male predominance (60%). The determinant factors of sleep apnea syndrome were male gender (60% versus 40%, P=0.021), obesity (77.8% versus 62.7%, P<0.0001), diabetes (26.7% versus 15.5%, P=0.5) and dyslipidemia (54.4% versus 27.3%, P=0.0009). Life in urban areas, occupation and smoking were not correlated with SAS in our series. The control of hypertension was better in non-apneic patients compared to apneic patients (63.6% versus 38.9%, P=0.04). The visceral impact of hypertension in apneic patients was highly significant (77.8% versus 41.7%, P=0.014). Therapeutically, it was noted the preferential prescription of combination therapy in apneic patients compared to non-apneic patients (82.3% versus 74.4%).

[Clinical, microbiological and evolutionary profile of patients experiencing failures and relapses of tuberculosis in Ivory Coast]. / Profil clinique, microbiologique et évolutif des patients en situation d'échecs et de rechutes de tuberculose en Côte d'Ivoire.

INTRODUCTION: Multidrug-resistant tuberculosis (MDR-TB) is a major obsession for TB control. The main risk factor for MDR-TB remains a history of TB treatment especially bad conduct. The objective of this study is to describe the profile of patients in situations of failure and relapse of tuberculosis. METHODS: We performed a retrospective survey of the analysis of records of patients starting TB retreatment for failure or relapse of tuberculosis. We used 193 cases with results of culture-sensitivity. RESULTS: The proportion of failure is 59/193 (30.6 %) and cases of relapse are 134/193 (69.4 %). The proportion of married life is 23.4 % (11/47) in chess against 41.5 % (51/123) in relapse of TB [P=0.021, OR=0.431 (0.201 to 0.927)]. Patients failing therapy have more chest pain [5.8 % (3/52) versus 0 % (0/126) with P=0.024]. The proportion of MDR-TB was 61.4 (38/59) in case of failure against 41 % (55/134) in case of relapse [P=0.002, OR=2.599 (1.378 to 4.902)]. The evolution is the same whatever the indication of reprocessing. CONCLUSION: The proportion of MDR-TB is very important in case of reprocessing failure and relapse of tuberculosis.

[Peripheral arterial disease of the lower limbs in African diabetic patients: ultrasonography and determining factors]. / Artériopathie des membres inférieurs du diabétique noir africain: aspects ultrasoniques et facteurs déterminants.

INTRODUCTION: Diabetic peripheral arterial disease (PAD) of the lower limbs is underdiagnosed. METHODOLOGY: This was a prospective study conducted over a six-month period from November 2012 to April 2013. A total of 308 diabetic patients were included from three diabetes centers in Abidjan (Ivory Coast). AIM: To screen for PAD of the lower limbs in a diabetic population and to identify the determining factors. RESULTS: Among the 308 patients, the ankle-brachial index (ABI) was<0.9 in 68 (22.07%) patients considered to have PAD; the ABI was>1.3 in 56 (18.2%) patients who had suspected mediacalcosis. The average age of the PAD patients was 60.2 years. Female gender predominated (55.9%). The mean duration of diabetes was 9.6 years: 97.1% type 2 diabetes. The other cardiovascular risk factors in this population were hypertension (58.8%) and dyslipidemia (40.9%). Smoking was present in 29.4% of patients and obesity in 23.9%. PAD of the lower limbs was mild in 46 patients (67.6%), moderate in 16 (23.5%) and severe in 6 (8.8%). Duplex Doppler commonly showed lesions of the tibial arteries. Determining factors of diabetic PAD of the lower limbs were hypertension (58.8% vs 36.6%; OR=2.46; 95% CI: 1.13-5.36; P=0.034) and dyslipidemia (40.9% vs 8.3%; OR=7.6; 95% CI: 2.31-25.08; P=0.0009). For mediacalcosis, male gender (71.5% vs 39.7; OR=0.26 95% CI/0.10-0.64. P=0.004) was the only factor identified. CONCLUSION: Hypertension and dyslipidemia were predictive factors for diabetic PAD of the lower limbs in our African population.

[Non-neuromeningeal cryptococcosis in patients with AIDS in Bamako, Mali: 2 case reports]. / Cryptococcose extra-neuroméningée au cours du sida à Bamako, Mali (à propos de 2 observations).

Non-neuromeningeal cryptococcosis forms resulting from disseminated infection are rarely reported in African literature and are non-documented in Malian medical ward. We report two clinical observations. Case 1: a 26-year-old patient, carrying the HIV-1 infection, in which the clinical examination revealed skin lesions simulating molluscum contagiosum and functional impairment of the lower limbs. Radiography of the lumbar spine showed vertebral osteolysis on L4-L5. Cryptococcal research remained negative in the CSF but positive at histological examination of the skin lesions and in pathological products of lumbosacral drainage. The treatment with fluconazole and ARV led to a favorable outcome. Case 2: a 42-year-old patient, admitted for fever cough, known for his non-compliance to ARVs and in which the examination found a syndrome of pleural condensation and a painful swelling of the outer third of the right clavicle (around the acromio-clavicular joint). Paraclinical investigations concluded in osteolysis of the acromial end of the right clavicle and an image of the right lung with abundant effusion. Cryptococcal research was positive in the pleural effusion and in the product of aspiration of acromio-clavicular tumefaction, negative in CSF. It seems important to think of a cryptococcal etiology even in the absence of clinical meningeal signs in front of any cutaneous sign and any fluctuating swelling in HIV+ patient.

[Malian first observation of disseminated African histoplasmosis with predominant bone localizations in an HIV-negative child in Bamako (Mali). Review of the literature]. / Première observation malienne d'histoplasmose africaine disséminée à prédominance osseuse chez un enfant VIH négatif. Revue de la littérature.

Endemic deep fungal infections are still under recognised diseases in daily medical practice because of their rarity in sub-Saharan area. The African histoplasmosis Histoplasma capsulatum var. duboisii (H. capsulatum duboisii) is the most frequent variety described in Mali through limited studies in adult patients, since the first case described by Catanei and Kervran (1945). Our case report is a disseminated histoplasmosis in a young 6-year-old african child. He was male and rural. The infectious localisations were mucosae, skin, lymphnodes, urinary tract and bones. Evolution has been marred by an episode of worsening of symptoms despite initial clinical improvement with ketoconazole. After healing of mucocutaneous lesions, we noticed a limitation of ampliation of both wrists. The radiographic bone lesions were lysis of the right lower end of the right radius and cubitus and fragmentation of cubital epiphysis of the same arm. Lacunes were present on the fifth right finger in metatarsus and phalanx; lacune and blowing aspect of the second phalanx of the left third finger was noted. The disseminated form of African histoplasmosis may occur in HIV-negative subject. The prognosis depends on early diagnosis and administration of appropriate and well-conducted therapy.

[Epidemiological, clinical and evolving HIV-positive patients referred to the University Hospital of Point G, Bamako, Mali]. / Profil épidémioclinique et évolutif de patients VIH positif, référés au CHU du Point G, Bamako, Mali.

We conduct a longitudinal descriptive study in the department of infectious diseases to CHU of Point G during 18 months. It concerned adult patients referred from another care center. All the patients underwent systematic clinical examination and complementary exploration. Our sample was 352 HIV+ patients, with a mean age of 37.8 ± 9.8 years and a sex ratio (M/F)=0.94 shared among patients receiving ARV treatment (ART-s) and not (n-ART). Delay of reference was 5 ± 4.4 days. All patients benefited from clinical and paraclinical examinations. In both groups patients were mostly from level II. On admission, 132 cases were ART-s (38%). The main reasons for consultation were mainly fever [87.9%, p <0.05] and vomiting [17.4%, p =0.005] in the ART-s. Cough (p=0.9), and diarrhoea (p=0.5] were most noted in the n-TARV no statistically significant (no SS). Other reference reasons were similar in the 2 groups: headache (p=0.4), dyspnea (p=0.1). Selected diagnoses were dominated by tuberculosis (p=0.6) for n-ART no SS. Nontuberculosis infectious pneumonia (p=0.8) and cerebral toxoplasmosis (p=0.8) were comparable in the two groups. Severe systemic bacterial infections occurred more noted in the n-TARV (p=0.7). Malaria has been the main non-AIDS defining disease in the n-ART [-p=0.07] no SS. Patients were seen to late stage a corollary of a more collapsed of immunity in n-ART group [93.3%, p <0.05]. The fatality rate was similar in both groups (43.2%). Pathological factors were mainly tuberculosis (p=0.3) no SS. The factors involved significantly in TARV-s were non-tuberculosis bacterial pneumonia (p=0.001). The hospital mortality of HIV and AIDS is still important. Despite free ARVs and the large number of support center, the delay in diagnosis is a key as well as the lack of monitoring of patients factor.

[Mortality and morbidity of tetanus in the infectious diseases department, Point G teaching hospital, in Bamako, Mali (2004-2009)]. / Morbidité et mortalité du tétanos dans le service de maladies infectieuses du CHU du Point G à Bamako, Mali (2004-2009).

Our study objectives were to determine annual cases of the tetanus and to describe its clinical, evolutionary and prognostic aspects. It was a transverse study from data records and medical records of patients aged 15 years and above hospitalized for tetanus in the service of infectious diseases of the Point G CHU from January 1, 2004 to December 31, 2009. The tetanus was diagnosed based on clinical (trismus, dysphagia, seizures and point consecutive to an injury) and epidemiological arguments (absence of a correct tetanus immunization, entry way). We collected a total of 119 cases of tetanus out of 1,839 hospitalizations making a prevalence of 6.5%. The hospitalization period was 5 days (73%) for most of the patients. Unskilled laborer and farmers were the most frequent with respectively 30.2 and 21.8% of cases. Tetanus occurred in the course of a traumatic road accident (16%) and from other traumatic causes (48.7%). The clinical form was a generalized type for 94.4% of the cases. A wound was the entry way for 64.7% of the patients. The entry way was located on the lower members 49.6% of the time. The co-morbidity was recorded with infection by Plasmodium falciparum (15 cases, 12.6%) and HIV (1 case). Hospital lethality was 46.2%. The death was statistically linked to clinical severity according to the Dakar score (P = 0.0005) and the Mollaret stage (P = 0.0001). A need for strengthening communication for behaviour change for the gaining of a correct and sustained immunization exists. A strategy based on the capacity building for a rapid tetanus diagnosis and a combined co-morbidities care may reduce the lethality in the context of our limited technical environment.

Management of hypertension in the elderly patient at abidjan cardiology institute (ivory coast).

Background. Since the treatment of hypertension is beneficial for the elderly, we have undertaken this study that aims to evaluate the management of hypertension in elderly patient in Côte d'Ivoire. Methods. A retrospective study was conducted among 854 hypertensive elderly patients of Abidjan Cardiology Institute who were followed for a minimum of one year, between January 2000 and December 2009. Results. The patients mean age was 73.1 ± 5.3 years, and 59% were women. At the first presentation, it was mostly systolic-diastolic hypertension (51.8%) and isolated systolic hypertension (38.5%). Mean blood pressure was 169.4 ± 28.4 mmHg for systolic, 95.3 ± 15.7 mmHg for diastolic, and 74.1 ± 22.8 mmHg for pulse pressure. Pulse pressure was ≥60 mmHg in 80.4%. According to the European Guidelines stratification of the cardiovascular risk-excess attributable to high blood pressure, 82.1% of the sample had a very high added risk. The pharmacological therapy was prescribed in 93.5%. More than 66% of patients were receiving ≥2 antihypertensive drugs including fixed-dose combination drugs. The most common agents used were diuretics (63.5%) followed by angiotensin-converting enzyme inhibitors or angiotensin receptor blockers in 61.3%. The most common agents used for monotherapy were calcium antagonists. When ≥2 drugs were used, diuretics and angiotensin-converting enzyme inhibitors or angiotensin receptor blockers were the most common. Blood pressure control was achieved in 42.6%. Conclusion. The control of elderly hypertension can be effective in Sub-Saharan Africa. He required at least two antihypertensive drugs to meet the recommended blood pressure target.

[Neuromeningeal cryptococcosis in Mali]. / La cryptococcose neuro-méningée au Mali.

Cryptococcal meningitis is the most common fatal central nervous system infection in AIDS patients in Sub-Saharan Africa. The purpose of this prospective study conducted from March 2003 to February 2004 in the internal medicine and infectious diseases departments of the Point G University Hospital Center was to investigate the clinical, prognostic and epidemiological profile of Cryptococcus neoformans infection in patients hospitalized for brain and meningeale infection (BMI). Diagnosis of neuromeningeal cryptococcosis (NMC) was based on positive identification of Cryptococcus by direct exam of the cebrospinal fluid (CSF) after India ink staining and/or culture on Sabouraud medium without actidione. During the study period, a total of 569 patients were hospitalized including 235 (41.3%) with HIV infection. Overall C. neoformans was identified in 14 patients. Median patient age was 39 +/- 8 years. There was a male preponderance with a sex ratio of 1.8 (9 men/5 women). Patients with BMI were HIV-positive in 85.7% of cases (n=12) and HIV-negative in 14.3% (n=2). The overall and HIV-specific prevalence of BMI was 2.5% and 5.1% respectively. The CD4 lymphocyte count was between I and 49 cells/mm3 in 64.3% of cases. The main clinical symptoms were cephalea in 85.7% of cases, altered consciousness in 50% and nausea/vomiting in 35.7%. Neurological manifestations (hemiparesis and cranial nerve deficit) were noted in 14.3%. HIV infection is the main purveyor of NMC in Mali. The actual incidence of cryptococcosis is unclear due to the poor sensitivity of diagnostic techniques. This study highlights diagnostic difficulties related to clinical polymorphism and poor technical facilities. Agglutination testing of blood and CSF is recommended, but mortality remains.

[Lymphocytic meningitis in Bamako, Mali]. / Les Meningites Lymphocytaires a Bamako, Mali.

We conducted a prospective survey from January 2001 to March 2002. Our objective was to study etiologic, clinic, and prognostic aspect of lymphocytic meningitis in hospital of Point G to Bamako. We included 35 patients with 25 male (71. 4%) and 10 female (28. 6%), sex - ratio (M / F) equal 2. 5. The median age was of 35 ± 25.4 years (range, 16 - 66 years). HIV serology was positive 26 cases (83. 9%). Clinical presentations were different. We observed 15 cases of encephalitis, 12 cases of meningoencephalitis, 2 cases of meningitis and 6 cases of febrile syndrome. Mean duration of hospitalization was 32. 6 ± 68 days. Mean of lymphocyte was 85.3 ± 25.9% among leukocytes in cerebrospinal fluid of 31 patients. Analysis of cerebrospinal fluid (CSF) identified in 9 cases Cryptococcocus neoformans. In 16 cases etiology was determination based on indirect arguments. In 9 cases viral meningoencephalitis diagnosis was made by exodiagnosis. It concerned 2 cases of TB meningitis, 1 case of cerebral toxoplasmosis, 1 case of decapitate bacterial meningitis and 1 case of cerebral tumor. Malaria thick smear permits to diagnosticate 1 case of cerebral malaria and 1 case of uncomplicated malaria. There are still 10 cases in which the cause remained unknown during study. HIV infection provides principally lymphocytic meningitis. Co morbidity with HIV is associated to lethality at 75%. But no statistical difference with patients without HIV (p = 0.52). Our work puts in exergue all problematic and hold correct of lymphocytic meningitis in our country.

[Atrial fibrillation: epidemiological data from the Cardiology Institute in Abidjan, Côte d'Ivoire]. / Fibrillation auriculaire: epidémiologie i l'institut de cardiologie d'Abidjan (Côte d'Lvoire).

UNLABELLED: The purpose of this retrospective study covering a 10-year period was to analyze epidemiological data and associated conditions related to atrial fibrillation (AF) in a cardiology hospital setting in SubSaharan Africa. PATIENTS AND METHODS: A total of 217 charts of patients hospitalized in the Medical Department of the Abidjan Cardiology Institute between August 1995 and August 2005 were reviewed. RESULTS: During the study, a total of 3,908 patients were admitted to the department, including 217 for AF for a hospital prevalence of 5.5%. There were 113 men (52%) and 104 women (48%) for a sex ratio of 1.08. Overall mean patient age was 58.9 years (range, 18 to 91 years). The difference in the mean age of men and women was not statistically significant: 57.8 versus 60 years respectively. The main symptoms at the time of admission to the hospital were exertional dyspnea (55.7%) and palpitations (22.1%). A total of 136 patients (62.6%) exhibited cardiac insufficiency. Heart disease was diagnosed in 192 patients including hypertensive cardiopathy in 48% and rheumatic valvular heart disease in 28%. The thromboembolic risk was moderate in 47% of patients (CHADS2 score, between 1 and 2) and high in 18.4% (CHADS2 score > or = 3). CONCLUSION: In our practice, hypertensive and rheumatic valvular heart disease were the main causes of AF that was associated with an alarming thromboembolic risk. These findings indicate that further effort is needed to prevent arterial hypertension and acute rheumatic joint disease.
