Incidence de l'epilepsie aprĂšs un accident vasculaire cerebral Ă Parakou en 2014
Introduction: les accidents vasculaires cérébraux (AVC) constituent une des principales causes acquises de l'épilepsie de l'adulte mais peu de données sont disponibles sur l'incidence de l'épilepsie aprÚs un AVC en Afrique. L'objectif de cette étude était d'estimer l'incidence de l'épilepsie chez les patients victimes d'AVC à Parakou.
Méthodes: il s'est agi d'une étude de type cohorte dynamique ayant inclus 203 patients victimes d'AVC et hospitalisés dans le service de neurologie du CHU de Parakou. Les patients aux antécédents d'épilepsie étaient exclus du suivi. Les patients étaient suivis sur une période de 21mois allant du 1er Janvier 2013 au 30 Septembre 2014. L'épilepsie était définie selon les critÚres de la Ligue Internationale contre l'Epilepsie.
Résultats: ils étaient ùgés de 18 à 99 ans avec une moyenne de 58,4 ans ± 14,2 ans. Le délai moyen de consultation aprÚs l'installation des symptÎmes était de 54,3h (+/-112,9h). Les AVC ischémiques représentaient 45,8%, les hémorragiques 31% et 23,2% d'indéterminés. L'incidence cumulée de l'épilepsie était de 17. La densité d'incidence de l'épilepsie était de 9,8 pour 100 personnes-années. Les facteurs associés à la survenue de l'épilepsie étaient le niveau d'instruction, la durée d'hospitalisation et le score de BARTHEL.
Conclusion: l'incidence de l'épilepsie reste trÚs élevée et la prise en compte des facteurs associés dans les stratégies de prise en charge pourrait permettre de réduire sa charge globale
Enquete sur la prevalence de la migraine chez lâadulte a titirou au Nord du Benin en 2017
Introduction: La migraine est une maladie neurologique frĂ©quente en population, source de handicap et classĂ©e 13Ăšme des affections les plus handicapantes par lâOMS. Lâobjectif de cette Ă©tude Ă©tait dâĂ©tudier la prĂ©valence de la migraine Ă Titirou en 2017. MĂ©thodes: Il sâest agi dâune Ă©tude transversale de type porte-Ă -porte menĂ©e sur 2065 sujets ĂągĂ©s de 18 Ă 65 ans. LâenquĂȘte a Ă©tĂ© effectuĂ©e sur une pĂ©riode de 4 mois allant du 10 avril au 05 aoĂ»t 2017. Les critĂšres diagnostiques de lâInternational Headache Society (IHS) de 2013 ont servi de base pour le diagnostic de la migraine. Les informations sociodĂ©mographiques, le poids et taille et les donnĂ©es relatives Ă la frĂ©quence et lâintensitĂ© des cĂ©phalĂ©es furent collectĂ©s. Les donnĂ©es ont Ă©tĂ© saisies, traitĂ©es et analysĂ©es grĂące au logiciel Epi Info version 2.2.0.165. RĂ©sultats: Il y avait une prĂ©dominance masculine avec un sex-ratio de 1,41. Les sujets Ă©taient ĂągĂ©s de 18 Ă 65 ans avec une moyenne dâĂąge de 31,87±8,37ans. La prĂ©valence des cĂ©phalĂ©es Ă©tait de 63,49%. La prĂ©valence de la migraine Ă Titirou Ă©tait de 3,82% [IC95% : (3,06%-4,72%)] (79 sur les 2065). Les facteurs associĂ©s Ă la migraine Ă©taient lâĂąge (p=0,0026), le sexe (p=0,0001), le niveau dâinstruction (p=0,0039), la profession (p<10-4 ) et lâindice de masse corporelle (p<10-4 ). LâintensitĂ© des cĂ©phalĂ©es Ă©tait modĂ©rĂ©e dans 44,30%, forte dans 51,90%, extrĂȘmement forte chez 3,80% des sujets. La plupart des migraineux (78,48%), avait moins de 5 crises par mois. La migraine avec aura reprĂ©sentait 49,4%. Les auras les plus observĂ©es Ă©taient les phosphĂšnes (34,18%), les scotomes (13,92%) et lâaura sensitive (13,92%). Les facteurs dĂ©clenchant les accĂšs Ă©taient le manque de sommeil (84,81%), la contrariĂ©tĂ© (68,35%) et le souci (62,03%). Conclusion : La migraine est assez frĂ©quente et sa prĂ©valence est comparable Ă celle rapportĂ©e dans la plupart des Ă©tudes en communautĂ© en Afrique.Mots clĂ©s: Migraine -PrĂ©valence-Adulte-Benin Introduction: The migraine is a common neurological disorder with a serious handicap and classified as the 13th disabling disease worldwide. The most consistently data on epidemiology of migraine are available in general population in Africa but not in northern Benin. We aimed to study the prevalence of migraine at Titirou in Parakou in 2017. Methods: This was a cross-sectional with door-to-door survey which included 2065 subjects aged 18 to 65 years. The survey was conducted over a period of 4 months from 10 April to 05 August 2017. The IHS diagnostic criteria of 2013 were used to define migraine. Socio-demographics information was collected. The data were analyzed using Epi Info 2.2.0.165.fr software. Results: There was a male predominance with 58.45% of men with sex ratio of 1.41. The mean age was 31.87 ± 8.37 years. The prevalence of headache was 63.49%. The prevalence of migraine in Titirou was 3.82% [95%CI: 3.06%-4.72%]. The associated factors were the age (p=0.00), the sex (p=0.00), level of education (p=0.00), occupation (p<10-4 ) and the body mass index (p<10-4 ). The migraine with aura represented 49.4%. The most type were visual aura (34.18%), sensitive aura (13.92%) and scotoma (13.92%).The intensity of headache was moderate in 44.30%, strong in 51.90%, extremely strong in 3.80% of subjects. The main triggering factors were lack of sleep (84.81%), annoyance (68.35%) and worry (62.03%). Conclusion: Migraine was more frequent in Parakou and this data are comparable to those reported elsewhere in sub-Saharan Africa.Key words: Headache, Migraine- Prevalence, epidemiology, Adult; Benin
Myasthenie auto-immune: diagnostic et prise en charge. A propos de six cas au Benin et au Gabon
La myasthĂ©nie est une maladie auto-immune qui se caractĂ©rise par une faiblesse musculaire fluctuante, sâaggravant Ă lâeffort et sâamĂ©liorant au repos, mettant en jeu le pronostic vital. Le polymorphisme clinique de cette affection rend souvent le diagnostic clinique difficile. Aussi le dosage des anticorps anti rĂ©cepteur dâacĂ©tylcholine (AC anti Rach) et lâENMG sont les principaux outils du diagnostic. Les auteurs rapportent 6 cas de myasthĂ©nie pour mettre en relief les difficultĂ©s de diagnostic et de prise en charge en Afrique subsaharienne.Mots clĂ©s: Ac anti-Rach, MyasthĂ©nie, Ă©lectromyogramme, AfriqueEnglish Title: Myasthenia autoimmune: diagnosis and management. About six cases in Benin and GabonEnglish AbstractMyasthenia is a life threatening autoimmune disease presenting varying degrees of muscle weakness becoming worse during effort and released by rest. Its clinical polymorphism makes difficult the diagnosis. The anti-AChR antibodies testing and EMNG are the main diagnostic tools. The authors report 6 cases of myasthenia to underline the difficulties regarding diagnosis and management of this disease in sub-Saharan Africa.Keywords: Anti-AChR antibodies, Myasthenia, Electromyogram, Afric
Lâinfection a virus de lâImmunodeficience Humaine (VIH), facteur predictif de gravite et de mortalite des accidents vasculaires cerebraux au Centre National Hospitalier et Universitaire-Hubert Koutoukou Maga (CNHU-HKM) de Cotonou, Benin
Introduction: Lâatteinte du systĂšme nerveux central est frĂ©quente et prĂ©coce au cours de lâinfection Ă VIH. Cependant, la survenue de lâaccident vasculaire cĂ©rĂ©bral (AVC) au cours de lâĂ©volution naturelle du VIH est peu documentĂ©e.Objectif: DĂ©terminer la prĂ©valence hospitaliĂšre du VIH chez les patients AVC et comparer les caractĂ©ristiques cliniques des AVC entre les sujets infectĂ©s et non infectĂ©s par le VIH.MĂ©thode: Etude transversale qui sâest dĂ©roulĂ©e au CNHU-HKM de janvier 2008 Ă dĂ©cembre 2011. Elle a portĂ© sur 432 sujets tous hĂ©tĂ©rosexuels, atteints dâAVC confirmĂ© par un scanner cĂ©rĂ©bral et ayant bĂ©nĂ©ficiĂ© dâune sĂ©rologie VIH. Deux groupes ont Ă©tĂ© constituĂ©s. Le groupe des sujets AVC infectĂ©s par le VIH (AVCVIH+) et le groupe des sujets AVC non infectĂ©s par le VIH (AVCVIH-). La gravitĂ© de lâAVC sur la base du score NIHSS Ă lâadmission et la mortalitĂ© Ă J30 ont Ă©tĂ© Ă©tudiĂ©es. Le logiciel Epi info a servi Ă lâanalyse des donnĂ©es.RĂ©sultats: La prĂ©valence hospitaliĂšre du VIH chez les patients atteints dâAVC Ă©tait de 26,1% (113/432). LâĂąge moyen des PVVIH Ă©tait de 43 ± 7 ans. Aucun dâeux ne se connaissait VIH+ avant lâadmission. La mĂ©diane des CD4  était basse : 119±36/mm3. Il nây a pas de diffĂ©rence significative entre les deux groupes pour ce qui concerne lâĂąge (p=0,08), le sexe (p=0,24), lâantĂ©cĂ©dent dâHTA (p=0,2), lâantĂ©cĂ©dent de diabĂšte (p=0,231). En revanche, lâAVC ischĂ©mique (67,3% vs 62,4% ; p=0,02) et la mortalitĂ© Ă J30 (23% vs 10,5% ; p=0,007) Ă©taient significativement plus Ă©levĂ©s chez les sujets VIH+ que les VIH-. De mĂȘme, lâAVC Ă lâadmission (NIHSS>13 ; p=0,002) Ă©tait plus grave dans le groupe AVCVIH+ que dans le groupe AVCVIH-. Le risque de faire un AVC est multipliĂ© par au moins 2 lorsque le sujet Ă©tait sĂ©ropositif que sĂ©ronĂ©gatif pour le VIH, tous autres facteurs Ă©tant Ă©gaux par ailleurs (RR=2,3).Conclusion: Ces rĂ©sultats suggĂšrent que lâAVC est frĂ©quent au cours de lâinfection Ă VIH et peut ĂȘtre son mode de rĂ©vĂ©lation. De mĂȘme, lâinfection Ă VIH apparait comme un facteur de risque de mauvais pronostic au cours de lâAVC.Mots clĂ©s: AVC, VIH, gravitĂ©, mortalitĂ©, BĂ©ninEnglish Title: Human Immunodeficiency Virus infection (HIV), stroke severity and mortality predictive indicator in centre national Hospitalier et Universitaire-Hubert Koutoukou Maga (CNHU-HKM) Cotonou, BeninEnglish AbstractIntroduction: During HIV infection, the central nervous system is frequently affected. However, the occurrence of stroke during the natural course of HIV is poorly documented.Objectives: To determine the prevalence rate of HIV among stroke patients and to compare the clinical characteristics of stroke in people with HIV and those HIV free.Method: A Cross-sectional study was conducted in the Neurology department of CNHU-HKM in Cotonou from January 2008 to December 2011. It involved 432 subjects all heterosexual, with stroke confirmed by brain CT scan and who underwent HIV test. Two groups were formed. The group of stroke subjects with HIV infection (AVCVIH +) and that of stroke subjects not infected by HIV (AVCVIH-). Stroke severity based on NIHSS score at admission and mortality at day 30 was studied. Epi Info was used for data analyses.Outcome: The prevalence rate of HIV among patients with stroke was 26.1% (113/432). The average age of HIVâs subjects was 43 ± 7 years. None of them knew prior to admission that their status was HIV +. The median CD4 count was low: 119 ± 36/mm3. There is no significant difference between the two groups regarding age (p = 0.08), sex (p = 0.24), hypertension history (p = 0.2), diabetes history (p = 0.231). However, ischemic stroke (67.3% vs. 62.4%, p = 0.02) and mortality at day 30 (23% vs. 10.5%, p = 0.007) were significantly higher among HIV + than HIV-. Similarly, stroke on admission (NIHSS> 13, p = 0.002) was more severe in the group AVCVIH + than in group-AVCVIH. The risk of stroke is multiplied by at least 2 when the subject was HIV+ compare to HIV-, all other factors being equal (RR = 2.3).Conclusion: These results prove that stroke is common during HIV infection and may be one of its revealing factor. Similarly, HIV infection is a risk factor of poor outcome during stroke.Keywords: Stroke, HIV, AVC, severity, mortality, Beni
Epilepsie en milieu scolaire : Connaissance des enseignants sur lâĂ©pilepsie au sud du BĂ©nin
Objectif : Evaluer le niveau de connaissance des enseignants du primaire et du secondaire sur lâĂ©pilepsie.MĂ©thodes : Il sâagissait dâune Ă©tude transversale descriptive et analytique menĂ©e du 02 au 31 Mai 2019 au sud du BĂ©nin en milieu scolaire. Huit Ă©coles dâenseignements primaires et secondaires ont Ă©tĂ© choisi aprĂšs un sondage alĂ©atoire simple puis tous les enseignants prĂ©sents le jour de lâenquĂȘte et consentants ont Ă©tĂ© inclus. Leur niveau de connaissance a Ă©tĂ© Ă©valuĂ© grĂące Ă un score calculĂ© Ă partir des rĂ©ponses au questionnaire et les facteurs associĂ©s ont Ă©tĂ© dĂ©terminĂ©s.RĂ©sultats : Au total 189 enseignants dâĂąge moyen de 35,4 ± 7,6 ans avec une prĂ©dominance masculine (156 hommes) et une sex-ratio de 4,7 ont Ă©tĂ© enquĂȘtĂ©s. Le niveau de connaissance de lâĂ©pilepsie Ă©tait faible chez 59,8%. Pour 46,6% des enseignants, lâĂ©pilepsie Ă©tait contagieuse. LâĂąge (p=0,042) et lâanciennetĂ© dans lâenseignement (p=0,003) Ă©taient associĂ©s au faible niveau de connaissance ; les enseignants ĂągĂ©s de 30 Ă 40 ans et ceux ayant entre 1 Ă 5 ans dâanciennetĂ© avaient un plus mauvais niveau de connaissance sur lâĂ©pilepsie.Conclusion : Au sud du BĂ©nin, le niveau de connaissance des enseignants des Ă©coles primaires et secondaires sur lâĂ©pilepsie est faible, avec comme facteurs associĂ©s lâĂąge et lâanciennetĂ© dans lâenseignement. Des campagnes de sensibilisation sont indispensables pour la rĂ©duction de la stigmatisation qui est attribuĂ©e Ă lâĂ©pilepsie
Determinants of Adherence to Recommendations of the Dietary Approach to Stop Hypertension in Adults with Hypertension Treated in a Hospital in Benin
Abstract The dietary approach to stop hypertension (DASH) is an effective nutritional strategy to prevent and treat cardiovascular disease. Optimal benefit from dietary recommendations in management of hypertension depends on the compliance. This analytic cross sectional study aimed at establishing determinants of DASH among adults with hypertension treated at hospital in Benin. The study included 150 hypertensive adults selected during medical visit for blood pressure monitoring at hospital Saint-Luc in Cotonou from June 3 rd to July 1 st , 2014. Data on consumption of sodium, fruits and vegetables, alcohol, saturated and trans fat rich products were collected by questionnaire. A score of adherence to DASH was built. Determinants of adherence to DASH were identified using logistic regression model. Only 20% of subjects showed adherence to DASH. Better knowledge on hypertension OR=5.18 (95%IC 1.98-13.22) and healthy dietary habits and lifestyle prior to diagnosis of hypertension OR=4.26 (95%IC 1.67-13.18) increased the likelihood of adherence to dietary recommendations for hypertension management. Nutrition education and information of patients on hypertension and its complications during medical consultations may increase their adherence to dietary recommendations for management of the disease

Health system performance for people with diabetes in 28 low- and middle-income countries:A cross-sectional study of nationally representative surveys
International audienceThe prevalence of diabetes is increasing rapidly in low- and middle-income countries (LMICs), urgently requiring detailed evidence to guide the response of health systems to this epidemic. In an effort to understand at what step in the diabetes care continuum individuals are lost to care, and how this varies between countries and population groups, this study examined health system performance for diabetes among adults in 28 LMICs using a cascade of care approach
Association between country preparedness indicators and quality clinical care for cardiovascular disease risk factors in 44 lower- and middle-income countries:A multicountry analysis of survey data
BackgroundCardiovascular diseases are leading causes of death, globally, and health systems that deliver quality clinical care are needed to manage an increasing number of people with risk factors for these diseases. Indicators of preparedness of countries to manage cardiovascular disease risk factors (CVDRFs) are regularly collected by ministries of health and global health agencies. We aimed to assess whether these indicators are associated with patient receipt of quality clinical care.Methods and findingsWe did a secondary analysis of cross-sectional, nationally representative, individual-patient data from 187,552 people with hypertension (mean age 48.1 years, 53.5% female) living in 43 low- and middle-income countries (LMICs) and 40,795 people with diabetes (mean age 52.2 years, 57.7% female) living in 28 LMICs on progress through cascades of care (condition diagnosed, treated, or controlled) for diabetes or hypertension, to indicate outcomes of provision of quality clinical care. Data were extracted from national-level World Health Organization (WHO) Stepwise Approach to Surveillance (STEPS), or other similar household surveys, conducted between July 2005 and November 2016. We used mixed-effects logistic regression to estimate associations between each quality clinical care outcome and indicators of country development (gross domestic product [GDP] per capita or Human Development Index [HDI]); national capacity for the prevention and control of noncommunicable diseases ('NCD readiness indicators' from surveys done by WHO); health system finance (domestic government expenditure on health [as percentage of GDP], private, and out-of-pocket expenditure on health [both as percentage of current]); and health service readiness (number of physicians, nurses, or hospital beds per 1,000 people) and performance (neonatal mortality rate). All models were adjusted for individual-level predictors including age, sex, and education. In an exploratory analysis, we tested whether national-level data on facility preparedness for diabetes were positively associated with outcomes. Associations were inconsistent between indicators and quality clinical care outcomes. For hypertension, GDP and HDI were both positively associated with each outcome. Of the 33 relationships tested between NCD readiness indicators and outcomes, only two showed a significant positive association: presence of guidelines with being diagnosed (odds ratio [OR], 1.86 [95% CI 1.08-3.21], p = 0.03) and availability of funding with being controlled (OR, 2.26 [95% CI 1.09-4.69], p = 0.03). Hospital beds (OR, 1.14 [95% CI 1.02-1.27], p = 0.02), nurses/midwives (OR, 1.24 [95% CI 1.06-1.44], p = 0.006), and physicians (OR, 1.21 [95% CI 1.11-1.32], p ConclusionIn this study, we observed that indicators of country preparedness to deal with CVDRFs are poor proxies for quality clinical care received by patients for hypertension and diabetes. The major implication is that assessments of countries' preparedness to manage CVDRFs should not rely on proxies; rather, it should involve direct assessment of quality clinical care
