Amplification of blood smear DNA to confirm disseminated histoplasmosis.

BACKGROUND: The prevalence of the Histoplasma capsulatum var. capsulatum (Hcc) histoplasmosis may be underestimated West Africa, both because the diagnosis is not mentioned in the early stages of the disease and due to limited biological resources available. CASE REPORT: We report a case of disseminated histoplasmosis due to Hcc in a Senegalese HIV patient. The diagnosis was suspected following the demonstration of small encapsulated yeasts within neutrophils on a thin blood smear. It was further confirmed using a specific real-time PCR applied on a DNA specimen extracted from the thin blood smear. CONCLUSION: To the best of our knowledge, this is the first case of Hcc infection diagnosed in Senegal. Blood smear may be a valuable screening tool in the case of bloodstream dissemination and can be used for further molecular approaches to confirm the diagnosis.

[Effect of intermittent presumptive treatment with sulfadoxine-pyrimethamine on the acquisition of anti-VAR2CSA antibodies in pregnant women living in a hypoendemic area in Senegal]. / Influence du traitement présomptif intermittent par la sulfadoxinepyriméthamine sur l'acquisition d'anticorps anti-VAR2CSA chez la femme enceinte vivant en zone hypoendémique au Sénégal.

The impact of intermittent presumptive treatment (IPT) on the immunity of pregnant women in Senegal is still not very well known. We conducted a prospective study at the Roi-Baudouin maternity of Guediawaye in Senegal to assess IgG antibodies production against MSP1, GLURP and DBL5 in pregnant women under IPT. Blood samples were collected from the participating women at inclusion and delivery. Samples were analyzed after centrifugation for the detection of IgG antibodies in sera by Elisa. Informed consent was given by each study participant prior to their inclusion. A total of 101 eligible women aged from 18 to 44 were included in this study. Multigravidae women represented 70.3% of the study population, whereas primigravidae accounted for 29.7%. The IgG level decreased slightly from inclusion to delivery for the women with regard to anti-MSP1 (83.1at inclusion versus 79.5 at delivery, p = 0.52) as well as anti-GLURP-R2 (84.1 at inclusion versus 75.9 at delivery, p = 0.16). After adjustment for number of pregnancies, there was a significant decrease in the production of anti-VAR2CSA between inclusion and delivery (p < 0.05). By reducing the incidence of malaria during pregnancy, IPT reduced the acquisition of placental parasites antibodies suppressors which could delay the development of protective immunity against malaria. The application of IPT in pregnant women would thus be more appropriate in hypoendemic areas where malaria exposure is lower.

[The place of malaria in an infectious disease department in Dakar, Senegal]. / Place du paludisme dans un service de pathologie infectieuse a Dakar (Sénégal).

The aims of this study were to determine the place of malaria at the Infectious Disease Clinic in Dakar, Senegal, to identify diseases associated with malaria, and to assess malaria mortality with or without co-morbidity. The files of all patients hospitalized from 2001 to 2003 in whom at least one test for malaria (thick films/spears) was performed to detect malaria parasites were reviewed. Malaria was diagnosed in patients presenting fever and positive thick films demonstrating asexual blood stages of Plasmodium. Data were collected from hospital charts. A total of 416 patients presented malaria (prevalence rate, 25.9%). The male-to-female sex ratio was 1:7 and mean age was 33 +/- 18 years. Of the 416 patients diagnosed with malaria, 273 (65.6%) presented severe forms. The overall mortality rate of malaria with or without co-morbidity was 25.7% (107/416). There was not a statistically significant difference between mortality due to isolated malaria and malaria associated with tuberculosis (23.4% versus 18.5%) (p = 0.7) or tetanus (23.4% versus 17.6%) (p = 0.34). Conversely mortality of malaria in HIV-positive patients was higher (58% versus 19%) (p = 10(-6)). Thus, malaria is of major concern in our department.

Simulation training for emergency obstetric and neonatal care in Senegal preliminary results.

To describe a new training approach for emergency obstetric and neonatal care (EmONC) introduced in Senegal to strengthen the skills of healthcare providers. The approach was based on skills training according to the so-called "humanist" method and on "lifesaving skills". Simulated practice took place in the classroom through 13 clinical stations summarizing the clinical skills needed for EmONC. Evaluation took place in all phases, and the results were recorded in a database to document the progress of each learner. This approach was used to train 432 providers in 10 months and to document the increase in each participants' technical achievements. The combination of training with the "learning by doing" model ensured that providers learned and mastered all EmONC skills and reduced the missed learning opportunities observed in former EmONC training sessions. Assessing the impact of training on EmONC indicators and introducing this learning modality in basic training are the two major challenges we currently face.

[Pneumocystis pneumonia biological diagnosis at Fann Teaching Hospital in Dakar, Senegal]. / Diagnostic biologique de la pneumonie à Pneumocystis au centre hospitalier universitaire de Fann, Dakar, Sénégal.

BACKGROUND: Data relative to Pneumocystis pneumonia in sub-Saharan Africa are not well known. Weakness of the technical material and use of little sensitive biological tools of diagnosis are among the evoked reasons. The objective of this study is to update the data of the disease at the Fann Teaching Hospital in Dakar and to estimate biological methods used in diagnosis. MATERIALS AND METHODS: A descriptive longitudinal study was carried out from January 5th, 2009 to October 31st, 2011 in the parasitology and mycology laboratory of the Fann Teaching Hospital in Dakar. The bronchoalveolar lavages received in the laboratory were examined microscopically for Pneumocystis jirovecii by indirect fluorescent assay or after Giemsa or toluidine blue O staining. RESULTS: One hundred and eighty-three bronchoalveolar lavages withdrawn from 183 patients were received in the laboratory. Sixteen were positive for P. jirovecii at 9% frequency. Four among these patients were HIV positive. Indirect fluorescent assay allowed finding of P. jirovecii among 16 patients while Giemsa staining discovered P. jirovecii only in a single patient. No case was diagnosed by toluidine blue O staining. CONCLUSION: Pneumocystis pneumonia in Parasitology and Mycology Laboratory of Fann Teaching Hospital at Dakar was mainly diagnosed among HIV patients.

[Evaluation of the efficacy and safety of three 2-drug combinations for the treatment of uncomplicated Plasmodium falciparum malaria in Senegal: artesunate-amodiaquine, dihydroartemisinin-piperaquine, and artemether-lumefantrine]. / Évaluation de l'efficacité et de la tolérance des combinaisons artésunate-amodiaquine, dihydroartémisinine-pipéraquine et artéméther-luméfantrine pour le traitement du paludisme à Plasmodium falciparum non compliqué au Sénégal.

BACKGROUND: Since 2006, artemisinin-based combination therapies (ACT) have been used to treat uncomplicated Plasmodium falciparum malaria in Senegal, as recommended by WHO. Recently, decreased parasite clearance with artemisinin derivatives has been reported in Cambodia and Thailand. The effectiveness of artemisinin derivatives in Africa must be monitored. This study was conducted to evaluate the efficacy and the tolerability of three ACT widely used in Senegal. METHODS: From October 2010 to February 2011, a descriptive and analytical sequential study was conducted in adults and children to evaluate these three combinations: artemether-lumefantrine (AL), artesunate-amodiaquine (ASAQ), and dihydroartemisinin-piperaquine (DHAPQ). The study took place at the health posts of Deggo and Pikine and the health center of Guédiawaye, in the suburbs of Dakar. The primary endpoint was the PCR-corrected adequate clinical and parasitological response (ACPR) at day 28 (D28); the secondary endpoints included ACPR at D42, clearance times for parasites, fever, and gametocytes, and the incidence of adverse events. RESULTS: The study included 393 patients: 139 in the AL group, 130 in the ASAQ group, and 124 in the DHAPQ group. In the intent-to-treat population, PCR-corrected ACPR at day 28 was 92.8% in the AL, 89.2% in the ASAQ, and 91.1% in the DHAPQ (p = 0.58) groups, and in the per-protocol population, 98.4%, 98.3%, and 100% respectively (p = 0.39). At D42, ACPR was 99.2% in the AL, and 99.1% in each of the ASAQ and DHAPQ arms (p = 1). No early therapeutic failure (ETF) was observed. The combinations were well tolerated, with no serious adverse events reported during the follow-up period. CONCLUSION: These combinations are still effective and well-tolerated. Continued monitoring is nonetheless essential to detect early artemisinin resistance in Africa.

[Clear-fluid meningitis in HIV-infected patients in Dakar]. / Les méningites à liquide clair chez les patients infectés par le VIH à Dakar.

This retrospective study was carried out to describe the epidemiological, clinical and aetiological aspects of clear-fluid meningitis among HIV-positive patients admitted at the Infectious Diseases Clinic in Fann Teaching Hospital in Dakar Data were collected for analysis from patients files recorded from January 1, 2001 to December 31, 2003. Forty-six cases of clear-fluid meningitis were found among HIV-infected patients, representing 51.7% of cerebro-meningeal diseases and 92% of meningitis encountered in those patients. Sex ratio MIF was 1.5 and the mean age of patients was 40.7 years [range 23-61 years]. Clinical presentations comprised headache (80%), fever (67%), meningeal syndrome (74%), coma (28%), convulsions (9%), focal neurological deficits (11%), cranial nerves dysfunction (9%). Aetiologies were represented by neuromeningeal cryptococcosis (29 cases) and tuberculous meningitis (5 cases). In 26% of cases no aetiology was found. The case fatality rate was 63% overall (29 deaths) and 83.3% among cases with unknown aetiology. It did not vary significantly according to epidemiological and clinical variables studied. Neurological sequelae were found in 4 patients who recovered. A better management of clear-fluid meningitis among HIV-positive patients should benefit from the reinforcement of our diagnostic capacities, the availability of effective systemic antifungal drugs and the prevention of opportunistic infections in the course of HIV/AIDS infection.

[Update on neuromeningeal cryptococcosis in Dakar]. / Aspects actuels de la cryptococcose neuro-meningée à Dakar.

This study was carried out to provide current information on neuromeningeal cryptococcosis at the Infectious Diseases Clinic in Fann Teaching Hospital in Dakar. Epidemiological, clinical, biological and therapeutic data were collected retrospectively from files of patients treated between 1999 and 2003. A total of 45 cases including 34 in HIV-positive patients were analyzed. The prevalence of neuronieningeal cryptococcosis in H1V-infected patients was 2.9% in 2000 and, 7.9% in 2003. Only 6 patients had been using antiretroviral therapy. The male-to-female sex ratio was 2 and mean age was 34 years (range, 18-61 years). Clinical presentation involved fever (73.3%), persistent headache (86.7%), vomiting (66.7%), meningeal syndrome (60%), coma (20%), convulsion (13.3%), focal neurological deficit (15.6%), and cranial nerve dysfunction (11.1 %). The CD4-cell count was less than 200/mm3 in 14 of 15 patients tested. Cerebrospinal fluid was clear in most cases (88.9%) and lytuphocytic in half (52%) with a mean albumin concentration of 0.79 g/l. Positive results were obtained with India ink smears in 35 of 45 cases, cultures in 30 of 31 cases and cryptococcic antigen detection in CSF in 9 of 9 cases. The most frequently used antifungal drug was fiuconazole (93%). The mortality rate was 71.1% (32 deaths) overall and reached 78.9% in patients with less than 20 cells/mmm3 in CSF (78.9%). Three measures are necessary for control of neuromeningeal crytococcosis: routine screening in severely immunodeficient HIV patients, distribution of effective systemic antifungal drugs and primary prevention by widespread use of antiretroviral therapy.

[A case of meningoencephalitis caused by Acanthamoeba sp. in Dakar]. / Un cas de méningoencéphalite à Acanthamoeba sp. à Dakar.

Primary meningoencephalitis caused by free-living soil ameba is rare. We report the first diagnosed case of meningoencephalitis due to Acanthamoeba sp. in Senegal. The patient was a 24-year-old Senegalese woman hospitalized in the neurology department of Fann Hospital. Diagnosis was made 6 months after the onset of symptoms based mainly on headache with fever usually occurring in the evening, chills, and lumbar puncture demonstrating turbid fluid. Parasitological examination of cool cerebrospinal fluid sediment revealed the presence of free-living ameba trophozoites of the Acanthamoeba genus. Species determination by culture on 1.5% agar-agar enriched with Escherichia coli failed. The patient died one month following initiation of treatment using amphotericine B.

[Epidemiological, clinical, etiological features of neuromeningeal diseases at the Fann Hospital Infectious Diseases Clinic, Dakar (Senegal)]. / Profil épidémiologique, clinique et étiologique des affections cérébroméningées observées à la clinique des maladies infectieuses du CHU de Fann à Dakar.

OBJECTIVES: This retrospective study was carried out to determine the prevalence of cerebromeningeal diseases at the Fann Teaching Hospital Infectious Diseases Clinic, in Dakar, and to describe their epidemiological, clinical, and etiological features. PATIENTS AND METHODS: Data was collected for analysis from patients files recorded from January 1, 2001 to December 31, 2003. RESULTS: Four hundred seventy cases were identified (11.4% of total admissions) with a M/F sex ratio of 1.38 and a mean age of 33 years. Eighty-nine patients were infected by HIV and clinical presentations included fever (78%), meningeal syndrome (57.4%), coma (64.9%), convulsions (19%), focal neurological deficits (15.5%), and cranial nerves dysfunction (7.2%). Etiologies presented as cerebral malaria (85 cases), purulent meningitis (51 cases), neuromeningeal cryptococcosis (37 cases), tuberculous meningitis (11 cases), intracranial abscess (10 cases), toxoplasma encephalitis (4 cases), cerebrovascular attack (11 cases), and cerebromeningeal hemorrhages (3 cases). In as many as 248 cases (52.8%) no etiology could be found. The case fatality rate was 44.5% overall (209 deaths) and 68.5% among HIV-infected patients. Neurological sequels were found in 22 survivors (8.8%), consisting in focal neurological deficit (12 cases), deafness (5 cases), diplopia (2 cases), dementia (2 cases), postmeningitic encephalitis (1 case). CONCLUSION: These results show the need to improve our technical capacities in our diagnostic laboratories, the prevention of opportunistic infections in the course of HIV/AIDS infection, and the involvement of various specialists in the management of cerebromeningeal diseases.

[Toxoplasmosis in Dakar. Seroepidemiologic sampling of 353 women of reproductive age]. / La toxoplasmose à Dakar. Sondage séroépidémiologique chez 353 femmes en âge de procréer.

Thanks to a serological survey carried out in Dakar from January to November 1993 among 353 procreative women, immune cover regarding toxoplasmosis was assessed using ELISA methodology: 40.2% of the surveyed population had antibodies of toxoplasmosis. No evidence of age, pregnancy, number of previous pregnancies was noted in antitoxoplasmosis antibodies prevalence. The seroconversion risk seems to be low even when it has existed during pregnancy. Contamination occurred during childhood. Some sanitary education should be provided to the procreative population in order to achieve a better compliance with basic hygiene regulations during pregnancy.

[Heterogeneity of chloroquine resistant malaria in Senegal]. / Hétérogénéité du paludisme chloroquinorésistant au Sénégal.

In order to evaluate the in vivo efficacy of chloroquine in the treatment of P. falciparum malaria, studies have been carried out in Richard-Toll, Fatick and Tambacounda, 3 areas where dynamics of transmission, population movements, as well as prophylactic and curative practises are different. Failure rates in treatment were 13% in site 1 (Richard-Toll) where medical pressure and population movements are high. In sites 2 and 3 (Fatick and Tambacounda), the failure rate was 3%. Even if medical pressure is lower in the latter site (Tambacounda), the higher transmission could be a factor in the spreading of resistance. A surveillance system and better use of chloroquine must be undertaken.

[Impact of antimalarial drug accessibility on malarial morbidity and chloroquine resistance. A study carried out in Touba (Senegal)]. / Impact de l'accessibilité aux antipaludéens sur la morbidité palustre et la chloroquinorésistance. Etude menée à Touba (Sénégal).

In Touba, more important accessibility to antimalarial drugs and their uncontrolled use let to assure that the rate of malarial morbidity would be lower there than in other place in Senegal whereas the rate of chloroquine resistance would be higher. A checking survey of these assumptions has been carried out from october 15 to november 10, 1995 in Touba's health center. Among 227 feverish subjects investigated, 111 were Plasmodium falciparum carriers. Malarial bouts accounted for 48.9% of the feverish fits observed and for the major cause of consultation during the rainy season. These figures are higher than those usually observed in urban environment. Conversely, the rate of chloroquine resistance is lower than those observed in urban zones, since the therapeutic efficacy of chloroquine on Plasmodium falciparum was 100% in that survey.

[Efficacy of the combination of DEET (20%) and EHD (15%) against mosquito bites. Results of a study carried out in Senegal]. / Efficacité de l'association DEET (20%) et EHD (15%) contre les piqûres de moustiques. Résultats d'une étude de terrain effectuée au Sénégal.

The authors report the results of a survey on the efficacy against mosquito bites of a repellent, Mousticologne Spécial Zones Infestées (DEET 20%, EHD 15%). Two forms of the product, spray and gel, were tested in Senegal. Repellent efficacy was evaluated by exposing volunteers, both repellent-treated and untreated, to mosquito bites. The number of mosquito bites per person and per night was 0.63 in the spray treated group (group 1), 6.03 in the gel treated group (group 2) and 94.17 in the untreated group (group 3). The analysis of these results showed a significant difference between treated and untreated persons. Untreated persons were not protected against mosquito bites, persons treated with the spray were protected for 12 hours and those treated with the gel had over 8 hours' protection. We concluded that a single application of the repellent Mousticologne in the field is capable of ensuring all-night protection against mosquito bites.

[Intestinal parasites in the vendors and consumers of street food. A study conducted in the Dakar area]. / Parasitoses intestinales chez les vendeurs et les consommateurs d'aliments de rue. Etude menée au niveau de l'agglomération dakaroise.

In order to assess the parasitic risk for street-food consumers, the authors conducted two studies from September to August 1996, one on street-food sellers (305) and the other on consumers (235). Among the consumers, 127 were considered as not exposed to risk, since they did not frequent the sector being surveyed, and 108 were exposed because they consumed at least one meal per day cooked by the sellers of this area. Both groups filled out a questionnaire and had their stools analysed according to the RITCHIE method. The infection rate was 60% among sellers and 45.5% among consumers. Protozoans were predominant in both groups. Among the consumers, those exposed were significantly more infected. Even though the sellers represent a parasitic risk due to their level of infection and the typology of parasites they shelter, one cannot assume that consumers are contaminated only by the sellers of street food. However, appropriate measures must be implemented in order to minimize risks for street-food consumers.

[Malaria in the southern sanitary district of Dakar (Senegal). 1. Parasitemia and malarial attacks]. / Le paludisme dans le District sanitaire sud de Dakar (Sénégal). 1. Parasitémie et accès paludéens.

A survey of endemic malaria in Dakar was carried out in the southern sanitary district covering the city centre and neighbouring areas. The survey was scheduled from June 1994 to May 1995 in 12 sites distant from each other by 1000 to 1500 meters. Clinical and parasitological data were collected during weekly medical follow-ups at the patients' home with the systematic research of Plasmodium once a month. The study included 2,337 persons aged between 1 month and 88 years and belonging to 284 volunteer resident families. Through monthly parasitological examinations, a parasite rate (P.R.) of 0.3% and a gametocyte rate (G.R.) of 0.005% were recorded. Only Plasmodium falciparum was observed. The P.R. varied according to age: from 0.1% in the children under 2 years to 0.7% in the young adults (15-20 years) who appeared significantly more affected than the other age groups, including that of children from 2 to 9 years, of whom only 0.3% were infected by the parasite. The P.R. varied also according to the site surveyed: from 0% in the city centre to 1.3% at the periphery of the sanitary district and according to the time of year, reaching its height of 0.8%, between October and December, that is just after the rainy season. At the end of the year of survey, 929 among those surveyed were considered to have been satisfactorily followed. Their annual incidence rate was 2.4% for the parasitemia and of 1.5% for the malaria attacks. None of the participants aged under 2 years had the parasite. Among the others, the annual incidence rate varied according to the age--although not significantly--passing from 1.1% to 5.3% for parasitemia and from 0.4% to 3.0% for malaria attacks. Theses rates did not differ significantly according to site; the cases registered varied between 1% and 8% for parasitemia and 1% and 5.8% for malaria attacks. Only 10.6% of febrile subjects suffered from malaria attacks, but this rate seemed to go up between October to December, rising to 26.6% which corresponds to 1 case of malaria attacks for 4 cases of hyperthermia in that period. Weak density of Anopheline population and satisfactory medical surveillance explain the recorded results.

[Evaluation of the treatment of malaria using a 3-day regimen of quinine in Dakar]. / Evaluation du traitement du paludisme par la quinine en cure de 3 jours à Dakar.

The efficacy of quinine treatment for Plasmodium falciparum strains remains sound. However reports of decreased sensitivity and resistance of some strains in Asia and East Africa indicate that current treatment regimens should be re-adjusted. The purpose for the present study carried out in Dakar, Senegal, was to evaluate the local regimen for acute Plasmodium falciparum malaria using quinine at a dose of 20 mg/kg per day in two daily injections on 3 consecutive days. Thirty-seven patients with acute Plasmodium falciparum malaria including 10 severe cases were treated using the standard regimen and followed up clinically and parasitologically from Day 0 to Day 7. On Day 7 parasites were still detectable in the blood of four patients for a failure rate of 10.8%. Persistence of parasites despite disappearance of clinical symptoms suggests that the regimen should be increased to 25 mg/kg per day for at least for 3 days or longer if symptoms persist. Due to its adverse effects and cost (10 times higher than chloroquine treatment), quinine treatment should be prescribed only for patients with severe malaria forms.

[Health personnel and population practices in the diagnosis of malaria and use of antimalarial drugs in Dakar]. / Pratiques des personnels de santé et des populations en matière de diagnostic du paludisme et d'utilisation des antipaludéens à Dakar.

The practices of health care workers and the population with regard to diagnosis of malaria and use of antimalarial drugs were studied in the city of Dakar from September 1991 to March 1992. Study included 847 heads of family, 191 treatment prescribers including 77 physicians, 53 nurses and 61 midwives, and 60 pharmacists. Three separate questionnaires were used: one for the population, one for physicians and paramedical staff, and one for pharmacists. The data collected showed that the 4 main symptoms used by both health care workers and the general population for diagnosis of malaria were fever, chills, vomiting, and headache. Treatment was administered upon suspicion of infection by 72% of treatment prescribers. Chloroquine was the drug most widely used by prescribers and for self-treatment of malaria. Prophylactic drug treatment was practised by all groups studied except treatment prescribers but was unappropriate for the target groups. Chloroquine is the drug most widely used to protect against the disease. Pharmacists have adequate supplies but distribution is poor. Despite promising results in the fight against malaria, further effort is needed to train health care workers and provide information to the population.

[Malaria lethality in Dakar pediatric environment: study of risk factors]. / Létalité palustre en milieu pédiatrique dakarois: étude des facteurs de risque.

To determine risk factors for fatal malaria in Senegalese children, a 3-year case-control study was carried out between October 1992 and November 1995 at the Albert Royer Hospital in Dakar. The case group included 52 children who died from documented malaria in the hospital. The matched control group consisted of children who responded favorably to hospital treatment. Exposure to risk was measured with regard to age, nutritional status, educational level of parents, self-medication prior to hospitalization, socioeconomic level, degree of fever, and blood parasite levels. Cases and controls were compared using statistical tests for matched groups. Age lower than 5 years, poor educational level of parents, delay of treatment more than 24 hours, nutritional status, and blood parasite levels greater than 5% were associated with a significantly higher risk of fatal outcome. Conversely, low socio-economic level, recent self-medication, and fever over 41 degrees C were not associated with higher fatality. These findings emphasize the need for more information campaigns to encourage people to seek institutionalized care when fever appears. Our results also suggest that prophylactic treatment may be advisable in children under 5 years of age and in some high risk groups.

[Knowledge and treatment of malaria in rural Senegal]. / Connaissances et circuits thérapeutiques relatifs au paludisme en zone rurale sénégalaise.

Evaluating knowledge about the diagnosis and treatment of malaria is a prerequisite for both understanding the development of chemoresistance and improving ongoing programs of chemotherapy and chemoprophylaxis. To gain such knowledge we distributed a questionnaire to 900 household heads in twelve villages in the M'Backe district of Senegal. Awareness of the main symptoms of malaria was satisfactory in comparison with previous references. Public health care facilities such as dispensaries were cited as the first resort for treatment by 72.6% of respondents. Chloroquine was mentioned as the first line antimalarial by 23% of respondents who practiced self-medication. Improper dosages were stated by 60% of the respondents. A total of 52.3% of respondents practiced chemoprophylaxis mainly using chloroquine. In 65.8% of cases antimalarial drugs were obtained from public health care units but drugs were purchased on the market in 15.7% of cases. These findings indicate the threefold Bamako initiative should be reinforced and that a campaign should be undertaken to educate people living in rural areas about malaria.

PIP: Primary health care strategies against malaria as developed by the WHO and put into effect in Senegal in its national antimalarial program depend considerably upon the early identification and proper management of the condition, such as effective chemoprophylaxis among pregnant women. A survey was conducted of 900 household heads living in 12 villages in the M¿Backe district of Senegal to learn about their diagnostic and treatment practices related to malaria. Public health care facilities such as dispensaries were cited by 72.6% of the heads as their first resort for treatment. Chloroquine was noted as the first-line antimalarial by 23% of respondents who practiced self-medication, but inappropriate doses were noted in 60% of cases. 52.3% of respondents practiced chemoprophylaxis, usually with chloroquine, with such chemoprophylaxis practiced most often in households whose heads were relatively better educated. 65.8% of heads obtained antimalarial drugs from public health care units, but drugs were bought on the market in 15.7% of cases. These findings indicate that the Bamako Initiative should be reinforced and that a campaign should be launched to teach people living in rural areas about malaria.
