Experience de la premiere formation medicale continue en echographie destinee aux medecins generalistes et sages-femmes a l'UFR des sciences de la sante de Saint-Louis

Introduction. L'echographie est une modalite d'imagerie medicale non irradiante avec une innocuite parfaite. Ce travail rapporte la premiere experience de formation en echographie a l'UFR des sciences de la sante de Saint-Louis. L'objectif etait de renforcer les connaissances et savoir-faire en echographie de 11 medecins generalistes et 11 sages-femmes. Methode La formation s'est deroulee sur 13 semaines; avec un tronc commun portant sur les connaissances de base; et la pratique de l'echographie gyneco-obstetricale. A la fin du tronc commun; les sages-femmes debutaient les stages et les medecins poursuivaient la formation en echographie abdomino-pelvienne avant leurs stages. Des tests ont precede et cloture la partie theorique qui s'est deroulee sous forme d'exposes illustres d'images et cas pratiques. L'evaluation reposait sur le nombre d'objectifs atteint et l'assiduite. Resultats : 19 apprenants sur 22 ont valide la formation. Entre le pre-test et le Post-test; il y'avait chez les sages-femmes une progression de la moyenne de 66;6 et de 85;7 chez les medecins. L'assiduite etait satisfaisante. Le meilleur score d'objectif atteint chez une sage-femme etait de 100; et le score minimale chez elles etait de 85;5; avec une moyenne de 97;1 et un ecart type de 4;6. Chez les medecins le meilleur score etait de 95; le plus faible etait de 4;8 avec une moyenne de 72 et un ecart type de 3;1.Conclusion : Cette experience enclenche le processus de regionalisation de la formation medicale continue dans les universites senegalaises facilitant l'acces aux agents de sante a la formation medicale continue

Apport de l'IRM haut champ dans la prise en charge des cancers du col de l'uterus au Senegal

Objectifs: Decrire le profil des cancers du col de l'uterus au CHU de Fann avec une classification FIGO-IRM et situer l'interet de l'IRM dans la recidive post-operatoire. Patientes et Methode : Etude retrospective monocentrique ayant inclus 30 patientes dont 3 apres chirurgie. Les examens etaient realises avec une IRM de 1;5 Tesla. Des sequences ponderees en T2 dans les 3 plans etaient realisees suivies d'une sequence de diffusion dans le plan axial. Les sequences dynamiques en ponderation T1 etaient realisees dans le plan axial perpendiculaire au grand axe du col; avec saturation de la graisse avant et apres injection de gadolinium. La taille et le signal des tumeurs ont permis de faire une classification FIGO-IRM. La recherche de ganglions et de recidives post operatoires chez trois femmes a ete realisee.Resultats : L'age moyen des patientes etait de 45;7 ans (31 ans-70 ans). La taille moyenne des tumeurs etait de 6;25 cm (2 cm-15;2 cm). Le seuil des 4 cm etait depasse chez 92% des patientes. Toutes les lesions apparaissaient en hyposignal T1; avec restriction de la diffusion. Leur signal en T2 etait variable avec une predominance des lesions en hypersignal intermediaire (72%) et le rehaussement apres injection etait note dans 96% des cas. Le stade II B FIGO-IRM etait le plus representatif (56%) suivi du stade IV A (28%); soit une extension aux parametres dans 84% de cas. Des ganglions suspects etaient notes chez 60% des patientes. Une patiente presentait une recidive post operatoire.Conclusion : L'IRM est devenu quasi incontournable dans le bilan pre-therapeutique et la recherche de recidive post-operatoire des cancers du col de l'uterus dans notre CHU

[Peripartum idiopathic myocardiopathy: prospective echocardiographic study]. / La myocardiopathie idiopathique du péripartum: étude prospective échocardiographique.

Still frequent in Africa, the idiopathic peripartum cardiomyopathy (PPC) is the subject of only few prospective studies. The aim of this prospective work was to assess the echocardiographic abnormalities of the PPC and to determine on 26 patients the evolution and the prognostic factors of this disease. Six women had mild to moderate pericardial effusion. The abnormalities of the wall motion, constantly found, were diffuse in 20 cases (77.1%) and localized or prevalent on the interventricular septum or the left ventricular posterior wall in the other cases. The cardiac chambers were dilated in 24 cases (92.3%). Left ventricular hypertrophy was noted among 16 patients (61.5%); it was eccentric in 15 cases. The left ventricular systolic dysfunction was constant. The other abnormalities were: the abnormal left ventricular relaxation (one case), low mitral and aortic flow (12 cases), the mitral (21 cases) and tricuspid regurgitation (five cases). One noted a septal hypertrophy and an isolated dilatation of the right ventricle. The mean follow-up was 7.3 +/- 1 month (1-18 months). Two patients died at the 4th and 8th month. Among the 24 survivors, 11 had normalized were: the gestity (p = 0.01), the parity (p = 0.01), the cardiothoracic ratio (p = 0.04), the left ventricular volumes (p = 0.02), and the parameters of left ventricular function. The echocardiography of patients with PPC usually shows a pattern of dilated and hypokinetic cardiomyopathy, but many variations are possible. Most of the patients keep echocardiographic abnormalities after mean term follow-up.

[Peripartum heart failure: the underestimated role of frequent diseases in the Sudan-Sahelian area]. / Les insuffisances cardiaques du péripartum: rôle méconnu des affections fréquentes en zone soudano-sahélienne.

Peripartum cardiomyopathy is rare in developped countries, but still frequent in Africa. It is defined as a heart failure occurring during peripartum, without any underlying etiology. Authors present 3 cases showing that heart failure before or after delivery may be due to causes which are frequent in the Sahelian area but generally misdiagnosed. Anemia, hypertension and rheumatic fever were the causes of heart failure in these 3 patients, but they were not apparent when the initial diagnosis was made. These observations emphasize that, despite the complex hypothesis trying to explain heart failure during the peripartum period, one should think about some frequent causes which can be misdiagnosed because of the pregnant state or the heart failure itself.

[Intraventricular thrombosis complicating peri-partum idiopathic myocardiopathy]. / Les thromboses intraventriculaires compliquant la myocardiopathie idiopathique du péripartum.

Ventricular thrombosis can complicate the development and worsen the prognosis in any case of hypokinetic dilated cardiomyopathy. In the present article, a study has been made of 6 reports of ventricular thrombosis selected out of 58 medical files on women with peri-partum idiopathic cardiomyopathy. Patient age ranged from 22 to 55 years. The clinical picture showed hypokinetic dilated cardiomyopathy, complicated by cardiac failure; with its onset during the last trimester of gestation or in the 6 months post-partum. In all patients, overall cardiac failure was observed, and in all cases the diagnosis of intracardiac thrombosis was made by echocardiography. In all 6 patients, a left ventricular apical thrombosis was detected. In 2 subjects, 2 and 3 left ventricular thrombi were respectively found. In 1 case, a left ventricular thrombosis was present. In another case, a right thrombosis associated with a left ventricular thrombosis was detected. Treatment was initiated with a combination of anticoagulants (heparin and K antivitamins), diuretic and vasodilatory treatment. The clinical outcome was favorable, with the disappearance of thrombi and signs of cardiac failure (between the 15th and 54th day). No embolic complication was observed. These findings clearly show the importance of prescribing an anticoagulant treatment as a preventive measure during PPICM. Even if severe embolic complications are a potential risk, anitcoagulant treatment can ensure a favorable outcome.

[Arterial pressure and body mass index of children and adolescents in a rural area of Thiadiaye, Senegal]. / Etude de la pression artérielle et de l'index de masse corporelle chez l'enfant et l'adolescent en milieu rural à Thiadiaye (Sénégal).

The purpose of this study is to assess the profile of blood pressure and body mass index of children and adolescents in a rural area in Africa. It is a prospective study concerning a sample of 465 children and adolescents in the district of Thiadiaye (Senegal). The ration boys/girls was 1.02. Blood pressure was higher in girls. The prevalence of hypertension was 5.1% for the children and 1.5% for adolescents. There was no significative variation in body mass index for children whereas we were noted an augmentation with age in adolescence. The parameters of corpulence are higher in girls in adolescence. The prevalence of obesity was 3% in children and 2.4% for adolescents. There was no correlation between blood pressure and body mass index. This study show many particularities in rural area as for as blood pressure and body mas index of children and adolescent are concerned.

[Survey of smoking in the rural area of Thiadiaye, Senegal]. / Enquête sur le tabagisme en milieu rural a Thiadiaye (Sénégal).

The objective of this article is to study the place of tobacco addiction in a rural area in Senegal. We have performed a transversal and domicillary study on a sample of adults and adolescents of the district of Thiadiaye (Senegal). The mean age of the studied population is 39 +/- 8.5 years (extremes: 12 and 100 years). The sex ratio is 0.85%. The prevalence of tobacco addict was 24.07%, 9% of the teenagers and 32% of the adults were smokers. Tobacco use was more frequent among men (89% 5%) than women (10.5%) (p < 10(-7)). The most common form was traditional tobacco: 62.1%. Cigarette was smoked in 14.4% of cases. The mean duration of tobacco use was 13 +/- -12.2 years. The mean consumption per day of traditional tobacco was 5.1 +/- 4, whereas the mean number of cigarettes per day is 12.3 +/- -7. Our study shows that tobacco occupies an important place in rural area in Senegal where coexist with traditional habits, a modern tobacco use represented by cigarette smoking.

Cclinical study of vscular risk factors in the adult in the Thiadiaye rural environment. / Etude clinique des facteurs de risque vasculaire chez l'adulte en milieu rural à Thiadiaye.

Authors report the results of a prospective study in a sample of the district of Thiadiaye, a rural area in Senegal. They studied blood pressure, body mass index and waist-to-hip ratio of 329 adults. The mean systolic blood pressure is 123 +/- 24.3 mm Hg and the mean diastolic blood pressure is 71.7 +/- 13.2 mm Hg. There is a positive correlation between blood pressure and age (p < 10(-9)). The prevalence of hypertension is 20.18% and one can note a female predominance (21% for women versus 18% for men). The mean body mass index is 21.1 +/- 10.6. There is no correlation between corpulence and age. Conversely, the body mass index is higher in female in all age groups (p < 10(-7)). The prevalence of obesity is 5%. Abdominal fat distribution is 41.6%: 64% for women and 9.7% for men (p = 0.003).
