[Prevalence of cardiovascular risk factors in semi-rural area in Senegal]. / Prévalence des facteurs de risque cardio-vasculaire en milieu semi-rural au Sénégal.

OBJECTIVES: We aim to determine the prevalence of cardiovascular risk factors in the semi-rural population of the community of Gueoul in Senegal. PATIENTS AND METHOD: This is a cross-sectional, observational and descriptive study. We conducted an exhaustive survey in 2012 according to the STEPS wise approach of the world health organization against Senegalese aged of 35 years and over who resided for at least 6 months in semi-rural area in the community of Gueoul. Pregnant women were excluded. Classical cardiovascular risk factors were collected and data analyzed using SPSS 18.0 software. The significance level was agreed for a value of P<0.05. RESULTS: We examined 1411 subjects (1052 women) with a mean age of 48.5±12.68 years. The main cardiovascular risk factors were dyslipidemia (61,1%), physical inactivity (56.2%), abdominal obesity according to the International Diabetes Federation (53.9%), hypertension (46.4%), global obesity (13%), diabetes (7.2%) and smoking (2.5%). Hypertension was significantly associated with diabetes (P=0.001), abdominal obesity (P=0.001) and global obesity (P=0.0001). Sedentarity (P=0.001), global obesity (P=0.0001) and hypertension (P=0.001) were more frequent in women. CONCLUSION: Cardiovascular risk factors are frequent and often associated in semi-rural area of Senegal, particularly in women. This condition should lead to develop prevention strategies of cardiovascular complications.

[Left ventricular hypertrophy in black African subjects with artery hypertension: Results of a cross-sectional survey conducted in semi-rural area in Senegal]. / L'hypertrophie ventriculaire gauche chez le sujet noir Africain hypertendu : résultats d'une enquête transversale, réalisée en milieu semi-rural au Sénégal.

OBJECTIVES: To assess the prevalence of left ventricular hypertrophy according to electrocardiographic and echocardiographic criteria among hypertensive patients living in semi-rural Senegalese area. PATIENTS AND METHODS: According to the World Health Organization STEPSwise approach, we conducted, in November 2012, a cross-sectional and exhaustive study in the population aged at least 35 years old and living for at least six months in the semi-rural area of Guéoul. We researched electrocardiographic and echocardiographic left ventricular hypertrophy in hypertensive subjects. Data were analyzed with SPSS 18.0 software version. The significance level was agreed for a value of P<0.05. RESULTS: We examined 1411 subjects aged on average of 48.5±12.7 years. In total, 654 subjects were hypertensive and screening of left ventricular hypertrophy (LVH) was effective in 515 of them. According to Sokolow-Lyon index, 86 subjects (16.7%) presented electrocardiographic LVH, more frequently in men (P=0.002). According to Cornell index and Cornell product, LVH was founded respectively in 66 (12.8%) and 52 subjects (10.1%), more frequently in female (P=0.0001; P=0.004). It was more common in grade 3 of hypertension however criteria. In echocardiography, prevalence of LVH was 2.2% (13 cases) according to the left ventricular mass, 9.3% (48 cases) according to the left ventricular mass indexed to body surface area and 8.2% (42 cases) according to the left ventricular mass indexed to height2.7. LVH was significantly correlated with the electrocardiographic LVH according to Sokolow-Lyon index (P<0.0001) and the grade 3 of hypertension (P=0.003). CONCLUSION: Although rare in hypertensive Senegalese living in semi-rural area, left ventricular hypertrophy is correlated with severity of grade of hypertension. Screening by electrocardiogram will allow better follow-up of these hypertensive subjects.

[Prevalence of atherosclerotic carotid plaques in semi-rural Gueoul, Senegal: Survey of 1411 subjects]. / Prévalence des porteurs de plaques d'athérome carotidiennes dans la population semi-rurale de Guéoul au Sénégal : enquête sur 1411 sujets.

AIMS: The purpose of this study was to investigate the prevalence of atherosclerotic carotid plaques and association with cardiovascular risk factors and vascular diseases in a semi-rural area of Gueoul in Senegal. PATIENTS AND METHOD: This was a cross-sectional, descriptive study over a period of one month in 2012 in Senegalese people who were older than 35 years, and resided in semi-rural Gueoul for at least six months. Carotid plaques were measured with a portable Doppler Diadop 50(®) and defined by an intima-media thickness greater than 1.5mm. P-values less than 0.05 were considered statistically significant. RESULTS: The survey involved 1411 individuals with a sex ratio of 2.93 and an average age of 48.5 years. Prevalence of risk factors was high: dyslipidemia (61.1 %), physical inactivity (56.2 %), abdominal obesity (53.9 %), hypertension (46.4 %), obesity (12 %), diabetes (7.2 %) and smoking (2.5 %). Prevalence of atherosclerotic carotid plaques was 6.8 %, including 42.7 % with bilateral plaques. Prevalence increased with age (P=0.001), hypertension (P=0.0001), diabetes (P=0.004) and metabolic syndrome (P=0.008). There were no significant associations with the other risk factors. The presence of carotid plaques was associated with medical history of stroke (P=0.01), myocardial infarction (P=0.02) and peripheral artery obstructive disease (P=0.5). CONCLUSION: Prevalence of atherosclerotic carotid plaques seems weak but it is associated with many cardiovascular risk factors. It requires measures for early diagnosis and prevention of cardiovascular diseases in Senegal.

Etude des relations entre le diabete de type 1 et les parodontites chez des enfants senegalais

Introduction : Le diabete sucre ou diabete de type 1 est une affection metabolique frequente qui concerne a la fois les adultes et les enfants. Il se traduit par des atteintes du parodonte qui aboutissent a des pertes dentaires. L'objectif de cette etude etait d'evaluer les relations entre le diabete sucre de type 1 et la survenue de la parodontite chez l'enfant au Senegal. Patients et methode : Il s'agit d'une etude transversale a vise etiologique qui a porte sur 50 enfants diabetiques de type 1 et 50 non diabetiques ages de 6 a 15 ans. L'etat bucco-dentaire et parodontal a ete evalue dans les deux groupes. La presence de parodontite etait objectivee par l'existence de toute poche parodontale 3 mm sur les incisives permanentes et premieres molaires qui ont fait leur eruption complete. L'evaluation du niveau d'hygiene a ete effectue avec l'indice de plaque de Silness et Loe; le saignement evalue par l'indice de Loe et Silness. Resultats : Le niveau socio-economique des parents des enfants diabetiques et non diabetiques etait similaire. L'hygiene buccale des enfants diabetiques etait significativement plus defectueuse que celle des non diabetiques (p= 0;00) et les parodontites etaient statistiquement plus importantes chez les diabetiques. Il y avait une correlation significative et positive entre l'age et la survenue de parodontite chez les enfants ages de 13-15 ans (p=0;00) mais il n'y a pas de relation avec l'equilibre glycemique; ni avec l'anciennete du diabete. Conclusion : Le diabete de type I se traduit se traduit chez l'enfant et l'adolescent senegalais par des parodontites. Cette atteinte n'est pas en rapport avec l'equilibre glycemique; ni avec l'anciennete du diabete

[Toxic nodular goiter]. / Les goîtres nodulaires toxiques.

INTRODUCTION: To date no study in our country was specifically dedicated on toxic nodular goiter. They were just mentioned in generally studies about hyperthyroidism. METHOD: The authors report a retrospective series of 62 cases of toxic nodular goitre collected between 1979 and 1999 at the internal medical clinic of Dakar teaching hospital. The diagnostic of toxic nodule was retained on following criteria: to existence of one or several thyroid nodule with signs or thyrotoxicosis, the existence of a hyperfixating nodule at 131 iodine scintigraphy. Increasing of T3 and/or T4 thyroide hormone. The aims of the study was to analyse the epidemiological, clinical, and therapeutics aspects. RESULTS: We are collected 49 cases of solitary nodule (79.03%) and 13 cases of multi nodular goitre (20.97%). In the cases of solitary nodule, mean age was 40 years, sex ratio of 0.04 (47 female, 2 men). The nodule was clinically diagnosed in 47 cases (95.9%) and extinctive in 73.5%. 34.3% of patients have cardiothyreosis. In the cases of multi nodular goitre mean age was 45 years, all cases were female, goitre was clinically identified in 95.3% (12 patients) and 46.5% had cardiothyreosis. 62% of patients were lost to follow up during medical treatment. Only 2 patients on the 37 who were addressed for surgery come back after thyroidectomy. CONCLUSION: This study confirm the predominance of toxic nodular goitre in young female, its severity related to cardiothyreosis and underlines the difficulties limited to the therapeutical care.
