[Functional prognosis of stroke in countries in the process of development: Senegal].

OBJECTIVE: To evaluate the functional outcome in patients followed in the department of neurology of Dakar for stroke. MATERIALS AND METHOD: Prospective longitudinal observational study from August 2003 to May 2005 included inpatients or outpatients with stroke one month or less from entry confirmed by computed tomography scan. Patients were followed monthly for 12 months. At each visit, data on functional autonomy measured by the Barthel index and the treatments received were collected. RESULTS: One hundred and seventy patients aged 25 to 90 years (mean 61+/-13 years) were evaluated. The sex ratio was 0.68. A total of 64.7% of strokes involved ischemic cerebral vascular accidents and 35.3% hemorrhagic vascular accidents. Right hemiplegia was present in 55.9%, left hemiplegia in 42.9% and bilateral paresis in 1.2% of patients. A total of 28.8% of patients died between d0 and d30, 50.6% within one year. At entry, the Barthel score was greater than 60 in only 4.7% of patients. After one-year follow-up, 58.3% of the patients had a Barthel score greater than 60, 19.1% had a score between 20 and 40 and 22.6% a score between 40 and 60. Only 53.5% received rehabilitation care. The parameters significantly associated with a functional recovery were age less than 55 years (P<0.05), hemorrhagic vascular accident as opposed to ischemic vascular accident (P<0.05), and earlier rehabilitation care under qualified personnel (P<0.01). DISCUSSION: Our study shows an important rate of mortality during the first year following stroke and the rather young age of our population. The parameters associated with a better functional recovery are comparable to most of the data in the literature. The results of our study suggest that it is possible to improve functional prognosis after stroke by setting measures of prevention of the risk factors and rehabilitation in the early management of hemiplegia.

Prevalence of epilepsy its treatment gap and knowledge, attitude and practice of its population in sub-urban Senegal an ILAE/IBE/WHO study.

A door-to-door survey was used to determine the prevalence of epilepsy among 4500 people within the Pikine Health District (population 480,000) Senegal. Prevalence was 14.2/1000, and 23.4% of all people with epilepsy had never received appropriate treatment. Figures for the prevalence had increased since a previous survey in 1989. In parallel a study of knowledge attitude and practice was performed in the same district. Salient findings were that: two-thirds of interviewees had at some time witnessed a seizure, 51% agreed when asked if epilepsy is caused by evil spirits, 35% said epilepsy is contagious, only about 18% said that traditional therapy is best, 60% would not mind their child to play with a child with epilepsy but only 32% would agree if their child would want to marry a person with epilepsy.

[Evaluation of the cost of stroke management in Dakar, Senegal].

The purpose of this one-year cross-sectional study conducted in 1997 was to estimate the direct cost of stroke management in the Neurology Department of Fann University Hospital in Dakar, Senegal. Data were collected about the type of care services required and related spending. Cost analysis was made in CFA Francs (CFAF), the Senegalese currency (1 USD = 500 CFAF in 1997). A total of 1260 patients were hospitalized in the department including 383 for stroke (30.4%). Mean age was 60.8 +/- 14.2 years and men accounted for 49.2% of the population. The mortality rate was 46.2% among hospitalized patients. A total of 33,573 medical acts were carried out including 12,052 (35.9%) for stroke management. The direct cost of stroke management was 32,614,442 CFAF with a mean cost of 78,426 CFAF per patient. The cost was 18,839 CFAF in the patient care unit (57.8%) and 4,954,635 CFAF in the neuroradiology unit (15.2%). The cost of health care personnel was 19,373,172 CFAF (59.4%) and the cost for drugs and other medical products was 8,253,246 CFAF. Health education programs aimed at increasing awareness of risk factors are needed to reduce the cost of stroke management in this difficult economic period.

[Plasma selenium and peripartum cardiomyopathy in Bamako, Mali].

Peripartum heart failure due to unexplained dilated cardiomyopathy is a common disorder as Savannak-Sahelian Africa. One of the many suspected risk factors identified is selenium deficiency. The purpose of this study was to measure plasma selenium levels in patients with peripartum heart failure due to cardiomyopathy in Bamako, Republic of Mali and compare data with healthy Sahalian women with the same obstetrical status. Plasma selenium was measured in a patient group consisting of 28 Malian women presenting peripartum heart failure and in a control group of 28 healthy breast-feeding Nigerien women of comparable age. The criteria for matching the two groups was parity (similar number of deliveries) since multiparity is a risk factor for peripartum cardiomyopathy. The Wilcoxon test (nonparametric) was used to compare the 2 groups considering up value < 0.05 as significant. Plasma selenium was significantly lower in patients from Mali than in controls from Niger (65 +/- 17 ng/ml vs. 78 +/- 17 ng/ml, p = 0.01). The results of this study showing lower plasma selenium in Bamako patients with peripartum cardiomyopathy than in a matching healthy control population confirms the previous data from the Niamey study.

[Prevalence of the use of skin bleaching cosmetics in two areas in Dakar (Sénégal)].

The use of skin bleaching cosmetics is an increasingly widespread phenomenon in Africa. If the negative sanitary effects of this practice are today well known, reliable statistics on the importance of the problem within the global population are rare. Our study, conducted in two popular areas in Dakar, Usine bene taly and Usine Niary Taly, had 2 objectives: to determine the prevalence of the use of skin bleaching cosmetics in the studied zones, to describe the prevalence according to the following variables: age, matrimonial situation, level and/or type of instruction, job, type of agents used. For that purpose, we conducted a transverse study on a representative sample of 600 women from 15 to 55 years old. This study reveals a prevalence of the use of skin bleaching cosmetics of 67.2%. The agents found are hydroquinone derivatives (61%), topical corticosteroids (37%) and agents from unknown origin (2%). The use of skin bleaching cosmetics is more important among young women between 30 to 44 years (72.5%), married (72.2%), analphabets (75%), working (77.6%). Studies conducted in Mali and Togo gave comparable results, which give perspectives for a prevention based on education an awareness.

The Côte d'Ivoire national HIV counseling and testing program for tuberculosis patients: implementation and analysis of epidemiologic data.

OBJECTIVES: To describe the implementation of a free, voluntary and confidential HIV counseling and testing program for patients with newly diagnosed tuberculosis at the eight large outpatient tuberculosis centers in Côte d'Ivoire, and to present epidemiologic findings on participating patients. DESIGN: HIV counseling and testing program with ongoing HIV serosurveillance. METHODS: HIV counseling and testing services were established at the two tuberculosis centers in Abidjan in 1989 and were extended to six centers in the Côte d'Ivoire interior in the first half of 1994. Characteristics of counseled patients, acceptance rates of HIV testing, and HIV serologic results were analyzed for all eight centers from 1994 to 1996. Temporal trends in HIV seropositivity rates were examined for the two centers of Abidjan from 1989 to 1996. RESULTS: From July 1994 through December 1996, 17 946 (91.8%) out of 19 594 patients who were counseled at the eight centers in Côte d'Ivoire consented to HIV testing, of whom 7749 (43.2%) were HIV-seropositive. The highest rates of 47.0 and 45.6% were found in the two centers in Abidjan, with rates ranging from 32.9 to 42.4% in the six centers in the interior. HIV-seropositive tuberculosis patients from each of the 50 districts in Côte d'Ivoire were identified. In Abidjan, the HIV seropositivity rate remained relatively stable among men (46.7% in 1989, 48.5% in 1991, 43.6% in 1996), but rose sharply among women from 32.7% in 1989 to 50.1% in 1996. CONCLUSIONS: The high HIV seropositivity rates among tuberculosis patients in all geographic regions of Côte d'Ivoire indicate that the HIV epidemic has now spread throughout the country. However, the successful implementation of an extensive HIV counseling and testing program for more than 37000 tuberculosis patients to date demonstrates the commitment of the Côte d'Ivoire Ministry of Health to integrating HIV/AIDS prevention activities with tuberculosis control efforts. When logistically and economically feasible, the extension of HIV-related social and clinical services to HIV-seropositive tuberculosis patients should be considered by other national tuberculosis control programs in Africa.

[Epidemiology of schistosomiasis in a suburban school area of Bamako (Republic of Mali)].

Epidemiology of schistosomiasis has been assessed in October, 1990 in three primary schools of a suburban district of Bamako: Magnambougou. It was a cross sectional study which was carried out on an hazardous sample of 549 pupils of 7 to 14 years old. The Kato-Katz and urine filtration methods were used to search schistosome eggs. The prevalence rate was 50% (256/512) in Schistosoma haematobium and 5.6% (26/464) in S. mansoni. Children from 11-14 years old were more infected by Schistosoma haematobium (59.4%), than those from 7-10 years old (35.2%) (p < 0.005). Among these children, 26.2% excreted more than 100 eggs per 10 ml of urine. The infection did not varied significantly no matter what the sex is (53.7 and 44.8% respectively in boys and girls) (p = 0.05). According to the residence, pupils living in Magnambougou were more infected (54.9%) than those of others district (31.1%) (p < 0.001). Likewise, S. haematobium infection was more important in A and C schools (64.9 and 73.2% respectively) than in B school (11.2%) (p < 0.001). Two major snails species which are the intermediate hosts of urine schistosomiasis in Mali (Bulinus truncatus and Bulinus globosus) were found in the shelters: however, B. truncatus was only infected in 13.1% (19/145). Contamination was local and "ruralization" activities (particularly gardening) seemed to be the most important displaying factor.
