RESUMO
It has been previously shown that there are some interethnic differences in susceptibility to malaria between two sympatric ethnic groups of Mali, the Fulani and the Dogon. The lower susceptibility to Plasmodium falciparum malaria seen in the Fulani has not been fully explained by genetic polymorphisms previously known to be associated with malaria resistance, including haemoglobin S (HbS), haemoglobin C (HbC), alpha-thalassaemia and glucose-6-phosphate dehydrogenase (G6PD) deficiency. Given the observed differences in the distribution of FcγRIIa allotypes among different ethnic groups and with malaria susceptibility that have been reported, we analysed the rs1801274-R131H polymorphism in the FcγRIIa gene in a study of Dogon and Fulani in Mali (n = 939). We confirm that the Fulani have less parasite densities, less parasite prevalence, more spleen enlargement and higher levels of total IgG antibodies (anti-CSP, anti-AMA1, anti-MSP1 and anti-MSP2) and more total IgE (P < 0.05) compared with the Dogon ethnic group. Furthermore, the Fulani exhibit higher frequencies of the blood group O (56.5%) compared with the Dogon (43.5%) (P < 0.001). With regard to the FcγRIIa polymorphism and allele frequency, the Fulani group have a higher frequency of the H allele (Fulani 0.474, Dogon 0.341, P < 0.0001), which was associated with greater total IgE production (P = 0.004). Our findings show that the FcγRIIa polymorphism might have an implication in the relative protection seen in the Fulani tribe, with confirmatory studies required in other malaria endemic settings.

FcγRIIa is known to be polymorphic; and certain variants are associated with different susceptibilities to malaria. Studies involving the Fulani ethnic group reported an ethnic difference in FcγRIIa-R131H genotype frequencies between the Fulani and other sympatric groups. No previous studies have addressed these questions in Burkina Faso. This study aimed to assess the influence of FcγRIIa-R131H polymorphism on anti-falciparum malaria IgG and IgG subclass responses in the Fulani and the Mossi ethnic groups living in Burkina Faso. Healthy adults more than 20 years old belonging to the Mossi or the Fulani ethnic groups were enrolled for the assessment of selected parasitological, immunological and genetic variables in relation to their susceptibility to malaria. The prevalence of the Plasmodium falciparum infection frequency was relatively low in the Fulani ethnic group compared to the Mossi ethnic group. For all tested antigens, the Fulani had higher antibody levels than the Mossi group. In both ethnic groups, a similar distribution of FcγRIIa R131H polymorphism was found. Individuals with the R allele of FcγRIIa had higher antibody levels than those with the H allele. This study confirmed that malaria infection affected less the Fulani group than the Mossi group. FcγRIIa-R131H allele distribution is similar in both ethnic groups, and higher antibody levels are associated with the FcγRIIa R allele compared to the H allele.

OBJECTIVE: To assess the feasibility of sustaining visual cervical screening and treatment services in Mali, and to evaluate their performance and impact in improving the provision of cervical cancer control, following an initial cross-sectional study. DESIGN: Descriptive study. SETTING: Bamako area, Mali. POPULATION: Women aged 30-59 years. METHODS: Routine visual screening and treatment services were organised through two hospitals and 14 health centres. Patients with positive visual screening tests underwent colposcopy and/or directed biopsies, and ablative or surgical excision treatment was offered to those with cervical intraepithelial neoplasia (CIN). MAIN OUTCOME MEASURES: Test positivity, detection and treatment rates for CIN and the sustainability of screening services. RESULTS: Of the 14,141 women screened, 1682 (11.9%) were positive and were referred for further investigations and treatment. Over 75% of the screen-positive women underwent colposcopy and/or biopsy. CIN 1 was detected in 383 women, CIN 2 in 88, CIN 3 in 37 and invasive cervical cancer in 497. More than 80% of women with CIN and 35% of those with invasive cancer received treatment. The test performance characteristics and treatment coverage of routine screening were similar to those observed in the preceding cross-sectional study. CONCLUSION: Visual screening and treatment services are sustainable and effective in improving cervical cancer control provision by health services in Bamako, Mali. It is essential to organise and sustain several point-of-care services in order to extend cervical cancer prevention in low-income African countries.

Fulani of Mali are known for their lower susceptibility to Plasmodium falciparum malaria than their neighbours, the Dogon, despite similar transmission conditions. However, the mechanisms underlying these differences are poorly understood, particularly those concerning antigenspecific immune responses. The Apical Membrane Antigen 1 (AMA1) and the Merozoite Surface Antigen 1 (MSP1) are two malaria vaccine candidates, which play a pivotal role during the invasion of parasites into erythrocytes, and in the case of AMA1, of hepatocytes. Therefore, we analyzed the level of anti-AMA1 and anti-MSP1 antibodies (FVO and 3D7 alleles), by using ELISA (Enzyme Linked Immuno Sorbent Assay) to investigate whether there are differences between the two ethnic groups. Our results show that the splenic rate, the level of anti-AMA1 and anti-MSP1 were significantly higher in Fulani compared to Dogon; while the parasite rate was lower in Fulani group compared to Dogon. Our results suggest that the lower susceptibility of Fulani to malaria could be due to the higher specific humoral responses against AMA1 and MSP 1 in Fulani's ethnic group compared to Dogon.

In Africa, malaria is responsible for 25-40% of all outpatient visits and 20-50% of all hospitalizations. In malaria-endemic areas, individuals do not behave the same toward the outcome of clinical malaria. The aim of this study is to determine the prevalence of malaria in the locality among the different ethnic groups, evaluate the place of malaria among febrile illnesses, and assess the relationship between fever and parasite density of Plasmodium falciparum. Studies on susceptibility to malaria between the Fulani and Dogon groups in Mali were conducted in Mantéourou and the surrounding villages from 1998 to 2008. We carried out six cross-sectional studies during the malaria transmission and longitudinal surveys (July to December depending on the year) during the 10-year duration. In longitudinal studies, clinical data on malaria and other diseases frequently observed in the population were recorded. It appears from this work that malaria is the leading cause of febrile syndromes. We observed a significant reduction in malaria morbidity in the study population from 1998 to 2008. The pyrogenic threshold of parasitaemia was 1,000 parasites/mm(3) of blood in the Dogon and 5,000 parasites/mm(3) of blood in the Fulani.We have also found that high parasitical densities were not always associated with fever. Malaria morbidity was higher among the Dogon than in Fulani. The immunogenetic factors might account for this difference in susceptibility to malaria between Fulani and Dogon in the area under study. With regard to this study, it is important to take into account the ethnic origin of subjects when interpreting data of clinical and malarial vaccine trials.

Studies performed in Burkina Faso and Mali showed differences in susceptibility to malaria between the Fulani and other sympatric ethnic groups, the Mossi and Dogon. We carried out a longitudinal survey and three cross-sectional studies from 2003 to 2005 in order to assess the prevalence of anemia in Dogon and Fulani. The distribution of the study population by sex was comparable between the two ethnic groups (p = ns). The Fulani are mainly cattle breeders and the Dogons, farmers. They were exposed to similar entomological inoculation rates, and studies on "knowledge, attitude, and practices" showed no difference between the two ethnic groups. The cross-sectional studies were performed during the intense malaria transmission season (in September 2003 and 2005) and during the dry season (in March 2004). Longitudinal clinical follow-up studies were performed from August to December 2005 using the WHO 28 days in vivo test, after administration of a curative dose of antimalarial drugs to patients with mild malaria. During the cross-sectional studies, both Fulani men and women had significantly lower hemoglobin levels than their Dogon counterparts; this difference was most evident in the women (in 2005: 9.4 g/dl in Fulani vs 10.7 g/dl in Dogon, p = 0.0002). Clinical longitudinal follow-up data showed that Fulani children aged 10-14 years have lower hemoglobin levels than Dogon children. At day 0, the mean of hemoglobin level was 9.6 g/dl in Dogon children vs. 8.7 g/dl in Fulani children (p = 0.01). At day 28, after malaria treatment, we also observed a significant difference in hemoglobin levels in children (10.6 g/dl in Dogon vs 9.3 g/dl in Fulani, p < 0.001). A stronger association between anemia and spleen enlargement was found in the Fulani (53.2% with spleen enlargement) than in the Dogon (32.9%) [p = 0.005]. The Fulani suffer more from anemia than the Dogon, despite their lower susceptibility to malaria. The difference in anemia between Dogon and Fulani must be further investigated to determine possible factors involved in malaria susceptibility.

Postpartum family planning is the prevention of pregnancy during the 12 months following childbirth. OBJECTIVE: To study the use of contraceptive methods in the postpartum period in the obstetrics gynecology department of the district hospital of the commune II of Bamako. MATERIALS AND METHODS: We conducted a descriptive and analytical cross-sectional study with prospective data collection from January 1, 2019 to December 31, 2020. All women who had given birth who had chosen and benefited from a contraceptive method were included. The statistical test used was Fisher's test with a significance level set at 5%. RESULTS: In 2 years, the contraceptive prevalence in the postpartum was 26.1%. More than 2/3 of counseling (61%) was done during prenatal consultations, 8% during the latency phase, 26% in the immediate postpartum and 5% during the postnatal visit. The most chosen methods were implants (47.1%), intrauterine device (29.6%), miro-progestin pills (12.5%), injectable progestogens (8%) and condoms (3.2%). CONCLUSION: Postpartum family planning contributes to increasing contraceptive prevalence.

RESUMO
INTRODUCTION: Contraceptive prevalence is low in Mali. The information provided by the media men can help to increase or decrease the use of contraceptive methods. OBJECTIVE: To study the knowledge, attitudes and practices of Bamako media Men on family planning. MATERIAL AND METHODS: We carried out a descriptive cross-sectional study with prospective data collection from June 1 to August 30, 2019. It concerned journalists and presenters of 15 radio and 6 televisions in Bamako. RESULTS: During the 3 months, 615 media Men agreed to participate in this study. These are men and women from 36 to 45 years old in 37.2% of cases, married in 81.3% of cases. The radio with 85.5% was their main source of information on family planning. They all knew at least one contraceptive method. The best-known methods were pills (94.3%), injectables (57%) and implants (49.1%). They were in favor of the practice of family planning in 77.2% of cases, 76.9% had already used a method and 56.7% had already hosted a program on family planning. CONCLUSION: Media men are essential in the transmission of information. The quality of the information provided by these Media men can be influenced by their personal perceptions and attitudes. Their better involvement in the promotion of family planning can help to increase contraceptive prevalence.
INTRODUCTION: La prévalence contraceptive est faible au Mali. Les informations transmises par les Hommes de médias peuvent contribuer à augmenter ou à diminuer l'utilisation des méthodes contraceptives.

Il s'agissait d'hommes et de femmes âgés de 36 à 45 ans dans 37,2% des cas, mariés dans 81,3% des cas. La radio avec 85,5% était leur principale source d'information sur la planification familiale. Ils connaissaient tous au moins une méthode contraceptive. Les méthodes les plus connues étaient les pilules (94,3%), les injectables (57%) et les implants (49,1%). Ils étaient favorables à la pratique de la planification familiale dans 77,2% des cas, 76,9% avaient déjà utilisé une méthode et 56,7% avaient déjà animé une émission sur la planification familiale. CONCLUSION: Les Hommes de médias sont essentiels dans la transmission de l'information. La qualité de l'information fournie par ces Hommes de médias peut être influencée par leurs perceptions et attitudes personnelles. Leur meilleure implication dans la promotion de la planification familiale peut contribuer à augmenter la prévalence contraceptive.
RESUMO
Cryptococcal meningitis is the most common fatal central nervous system infection in AIDS patients in Sub-Saharan Africa. The purpose of this prospective study conducted from March 2003 to February 2004 in the internal medicine and infectious diseases departments of the Point G University Hospital Center was to investigate the clinical, prognostic and epidemiological profile of Cryptococcus neoformans infection in patients hospitalized for brain and meningeale infection (BMI). Diagnosis of neuromeningeal cryptococcosis (NMC) was based on positive identification of Cryptococcus by direct exam of the cebrospinal fluid (CSF) after India ink staining and/or culture on Sabouraud medium without actidione. During the study period, a total of 569 patients were hospitalized including 235 (41.3%) with HIV infection. Overall C. neoformans was identified in 14 patients. Median patient age was 39 +/- 8 years. There was a male preponderance with a sex ratio of 1.8 (9 men/5 women). Patients with BMI were HIV-positive in 85.7% of cases (n=12) and HIV-negative in 14.3% (n=2). The overall and HIV-specific prevalence of BMI was 2.5% and 5.1% respectively. The CD4 lymphocyte count was between I and 49 cells/mm3 in 64.3% of cases. The main clinical symptoms were cephalea in 85.7% of cases, altered consciousness in 50% and nausea/vomiting in 35.7%. Neurological manifestations (hemiparesis and cranial nerve deficit) were noted in 14.3%. HIV infection is the main purveyor of NMC in Mali. The actual incidence of cryptococcosis is unclear due to the poor sensitivity of diagnostic techniques. This study highlights diagnostic difficulties related to clinical polymorphism and poor technical facilities. Agglutination testing of blood and CSF is recommended, but mortality remains.

INTRODUCTION: Kidney disease (KD) is defined as a set of functional, morphological and histological kidney abnormalities. It is a truly global public health problem. Its prevalence is estimated to be 50 times that of end-stage renal disease (ESRD). In Kayes, there is no data on the prevalence of kidney disease, hence the interest of this study. OBJECTIVES: to determine the prevalence of renal disease, its main causes and the main factors of aggravation of this pathology in the emergency department at hospital Fousseyni DAOU of Kayes. METHODOLOGY: Retrospective cross-sectional study carried out from January 1, 2014 to February 1, 2015. We included all hospitalized patients in whom a renal damage marker (elevation of plasma creatinine, urinary sediment abnormality, ultrasound, histology and significant proteinuria) has been found. RESULTS: the prevalence of kidney disease was 9.9% (109/1099). Eighty-nine met the inclusion criteria. The study population was composed of 47 women (52.8%) and 42 men (47.2%), with a sex ratio of 0.89 in favor of women. The average age was 40.09 years with a predominance of patients in the age group [40-59]. The main reasons for consultation were hypercreatininaemia (48.3%), edematous syndrome (16.9%), low back pain (10.1%). High blood pressure (55.1%) and lower extremity edema (46.1%) were the medical history frequently found in our study. The kidney disease found was in order of growth: chronic renal failure (51%); acute renal failure (28%); proteinuria (16%), hematuria (3%), morphological abnormality of the kidneys (2%). Tubulointerstitial nephropathy represented 64% of acute renal failure with P = 0.000306. Vascular nephropathy constituted 46.7% of chronic renal failure with P = 0.000251. No cases of glomerular nephropathy were found in patients over 60 years of age.The most common causes were represented by nephrotoxic drugs injuries; infectious; high blood pressure and diabetes. The most observed aggravating factors are herbal medicine, urinary tract infections, renal hypoperfusion and unbalanced hypertension. CONCLUSION: kidney disease is not uncommon in the emergency room at Hospital Fousseyni Daou of Kayes. The most common causes are nephrotoxic drugs, hypertension and diabetes.
INTRODUCTION: La maladie rénale (MR) définie comme l'ensemble des anomalies rénales fonctionnelle, morphologique et histologique. Elle est un véritable problème mondial de santé publique. Sa prévalence serait 50 fois celle de l'insuffisance rénale terminale (IRT). A Kayes, il n'existe pas de donnée sur la prévalence de la maladie rénale, d'où l'intérêt de cette étude. OBJECTIFS: déterminer la prévalence de la maladie rénale, ses principales causes et les principaux facteurs d'aggravation de cette pathologie dans le service des urgences de l'hôpital Fousseyni DAOU de Kayes. MÉTHODOLOGIE: Etude transversale rétrospective réalisée du 1er janvier 2014 au 1er février 2015. Etaient inclus, tous les patients hospitalisés chez qui au moins un marqueur d'atteinte rénale (élévation de la créatinine plasmatique, anomalie du sédiment urinaire, anomalie échographique ou histologique et une protéinurie significative) a été retrouvé. Les paramètres analysés étaient socio-épidémiologiques, cliniques et para-cliniques. Nous avons exclu tous les patients dont les dossiers médicaux étaient inexploitables. RÉSULTATS: la prévalence de la maladie rénale était de 9,9% (109/1099). Quatre-vingtneuf répondaient aux critères d'inclusion. La population d'étude était composée de 47 femmes (52,8%) et de 42 hommes (47,2%), avec un sex-ratio de 0,89 en faveur des femmes. La moyenne d'âge était de 40,09 ans avec une prédominance des patients de la tranche d'âge [40-59]. Les principaux motifs de consultation étaient hypercréatininémie (48,3%), syndrome Ådémateux (16,9%), douleur lombaire (10,1%). L'hypertension artérielle (55,1%) et Ådème des membres inférieurs (46,1%) étaient les antécédents pathologiques fréquemment retrouvées dans notre étude. La maladie rénale retrouvée était par ordre de croissance : insuffisance rénale chronique (51%) ; insuffisance rénale aigue (28%) ; protéinurie (16%), hématurie (3%), anomalie morphologique des reins (2%). La néphropathie tubulo-interstitielle représentait 64% des insuffisances rénales aiguës avec P= 0,000306. La néphropathie vasculaire constituait 46,7% des insuffisances rénales chroniques avec P= 0,000251. Aucun cas de néphropathie glomérulaire n'a été retrouvé chez les patients de plus de 60 ans.Les causes les plus fréquentes étaient représentées par les causes toxiques (médicaments néphrotoxiques) ; infectieuses ; l'hypertension artérielle et le diabète. Les facteurs d'aggravations les plus observés sont la phytothérapie, l'infection urinaire, l'hypoperfusion rénale et l'HTA non équilibrée. CONCLUSION: la maladie rénale n'est pas rare aux urgences de l'hôpital Fousseyni Daou de Kayes. Les causes les plus fréquemment rencontrées sont les médicaments néphrotoxiques, l'HTA et le diabète.
RESUMO
Rapid accurate laboratory diagnosis is necessary for effective malaria management. In Mali, meeting this prerequisite is impeded by underuse of laboratory diagnosis by clinicians, absence of qualified laboratory facilities in some locations, and poor continuous professional education of laboratory technicians. The twofold aim of this investigation was to perform quality control of thick smear readings made by laboratory technicians in 1998 and 1999 and to study the feasibility and diagnostic value of two rapid diagnostic tests (RDT), i.e., ParaSight and OptiMAL, in comparison with the thick smear technique in the period from 1998 to 2003. Quality control of thick smear readings indicated a 56% false positive rate with 49.3% concordance between laboratory technician readings and the reference centre. Trials using RDT showed that the OptiMAL test was more efficient with 97.2% sensibility, 95.4% specificity and 93% concordance in comparison with thick smear. A program of training, refresher courses, and regular didactic supervision (quality control) for laboratory technicians has been set up in Mali under the sponsorship of the "Fondation Mérieux" (ACTION BIOMALI) and the President's Malaria Initiative (PMI). These institutions provide funding for training as well as equipment and consumables in all public medical laboratories in Mali. The thick smear method is still being used as the reference technique, but use of RDT is to be implemented at all levels of the health care pyramid.

Schistosomiasis remains a major worldwide public health problem in several endemic areas despite implementation of control measures. Vaccination would be an effective, long-term treatment option for future control of schistosomiasis. Although several parasite antigens have been identified as schistosomiasis vaccine candidates, major hurdles must still be overcome to develop a vaccine suitable for clinical trials in the field. Better understanding of immune responses to Schistosoma infection in both animal models and humans suggests that development of a vaccine is possible. The purpose of this review is to summarize the mechanisms of protective immunity against Schistosoma infection and to provide perspective on the development of a vaccine.

AIM: The aim was to compare the maternal-fetal prognosis of pregnancies in large multiparous with that of other parities. MATERIALS AND METHODS: We conducted a case-control study from March 1st, 2014 to February 1st, 2015. It concerned all parturients admitted in our service during the study period. We have chosen 1 case for 2 witnesses. All the large multiparous were included as cases and as witnesses the primiparous, the pauciparous and the multiparous who gave birth just before and after the case. The statistical test was the Chi2 with a significance level at 5%. RESULTS: The frequency of pregnancy in the large multiparous was 4.93%. They were housewives in 84% of cases, unschooled in 74.7% of cases. The maternal-fetal outcome was dominated by uterine rupture in 0.6% of cases, immediate postpartum hemorrhage in 9.8% of cases, vicious presentations in 5.5% of cases and cord prolapse in 6.8% of cases. CONCLUSION: Large multiparity is common in our practice. It is a high-risk pregnancy because of its many maternal-fetal complications.
BUT: Le but était de comparer le pronostic materno-fÅtal des grossesses chez les grandes multipares à celui des autres parités. MATÉRIELS ET MÉTHODES: Nous avons réalisé une étude cas-témoins du 1er mars 2014 au 1er février 2015. Elle a concerné toutes les parturientes admises dans le service pendant la période d'étude. Nous avons choisi 1 cas pour 2 témoins. Ont été incluses comme cas toutes les grandes multipares et comme témoins les primipares, les paucipares et les multipares ayant accouchées juste avant et juste après le cas. Le test statistique utilisé a été le Chi2 avec un seuil de significativité fixé à 5%. RÉSULTATS: La fréquence de la grossesse chez la grande multipare était de 4,93%. Il s'agissait de femmes au foyer dans 84% des cas, non scolarisées dans 74,7% des cas. Le pronostic materno-fÅtal a été dominé par la rupture utérine dans 0,6% des cas, l'hémorragie de la délivrance dans 9,8% des cas, les présentations vicieuses dans 5,5% des cas et la procidence du cordon dans 6,8% des cas. CONCLUSION: La grande multiparité est fréquente dans notre pratique. C'est une grossesse à haut risque à cause de ses nombreuses complications materno-fÅtales.
RESUMO
OBJECTIF: the purpose of this work was to study the infections associated with the care in the department of gynecology - obstetrics of the University Hospital Center Gabriel Touré (CHU G. Touré). PATIENTS AND METHODS: This was an epidemiological, descriptive, and analytical study carried out in the gynecology-obstetrics department of G. Touré University Hospital, from April 11, 2016 to August 29, 2016 (4 monthset 18 days), with a prospective collection of data that focused on the characteristics clinical and laboratory-based care-associated infections in patients during their hospitalization. Included in the study were all hospitalized patients (operated or not) in the gynecology obstetrics department, who agreed to participate in the study. The criteria used to diagnose the infection associated with care were those of the CDC Atlanta and making a thick drop in our context. Operative wound monitoring was performed until the 30th postoperative day. RESULTS: We recorded 200 patients, including 138 operated and 62 nonoperated patients, of which 30 patients developed a care-associated infection at a rate of 15%. The mean age of the patients who presented an infection was 32.52 years ± 13.36 years against 29.36 years ± 10.28 years for the patients who did not present the infection. Seven point five percent of the evacuees had an infection associated with care. The most common types of infections were surgical site infection with 56.60% followed by malaria with 23.30% and urinary tract infection with 20.00%. Escherichia coli and Acinetobacter baumaniiwere the most recovered germs. Isolated organisms were 100% resistant to Amoxicillin, 88.88% were resistant to Ciprofloxacin and 77.77% were resistant to Amoxicillin + Clavulanic acid. The average duration of hospitalization for patients who developed the infection was 14.70 days with extremes of 5 and 46 days. The mortality rate was 1.50%. The average cost of management of patients who developed the infection was 119837 FCFA; the extremes were 17750 and 825750 FCFA and the standard deviation of 174998 CFA francs. CONCLUSION: the infections associated with the care remain frequent in our service and dominated by the infections of the operating site. The isolated organisms were all 100% resistant to Amoxicillin in 88.88% Ciprofloxacin.
LE BUT: de ce travail était d'étudier les infections associées aux soins dans le département de gynécologie obstétrique du Centre Hospitalier Universitaire Gabriel Touré (CHU G. Touré). PATIENTES ET MÉTHODES: Il s'agissait d'une étude épidémiologique, descriptive, analytique réalisée dans le département de gynécologie obstétrique du CHU G. Touré, allant du 11 Avril 2016 au 29 Août 2016 (4 mois et 18 jours) à collecte prospective des données qui a porté sur les caractéristiques cliniques et biologiques des infections associées aux soins chez les patientes au cours de leur hospitalisation. Etaient incluses dans l'étude toutes les patientes hospitalisées (opérées ou non) dans le service de gynécologie obstétrique, et qui ont accepté de participer à l'étude.Les critères utilisés pour le diagnostic de l'infection associée aux soins étaient ceux du CDC d'Atlanta et la réalisation d'une goutte épaisse dans notre contexte. Une surveillance des plaies opératoires a été faite jusqu'au 30ème jour post-opératoire. RÉSULTATS: Nous avons enregistrés 200 patientes dont 138 opérées et 62 non opérées parmi lesquelles 30 patientes ont développé une infection associée aux soins soit un taux de 15%. L'âge moyen des patientes ayant présenté une infection a été 32,52 ans ±13,36 ans contre 29.36 ans ±10,28 ans pour les patientes n'ayant pas présenté l'infection. Sept virgule cinq pourcent des patientes évacuées ont présenté une infection associée aux soins. Les types d'infections les plus retrouvés étaient l'infection du site opératoire avec 56,60% suivie du paludisme avec 23,30% et l'infection urinaire avec 20,00%. L'Escherichia coli et l'Acinetobacterbaumanii ont été les germes les plus retrouvés. Les germes isolés étaient dans 100% des cas résistants à l'Amoxicilline, dans 88,88% des cas résistants à la Ciprofloxacine et dans 77.77% des cas résistants à l'Amoxicilline +Acide clavulanique. La durée moyenne d'hospitalisation des patientes ayant développé l'infection a été 14,70 jours avec des extrêmes de 5 et 46 jours.Le taux de mortalité a été de 1,50%. Le coût moyen de prise en charge des patientes ayant développé l'infection a été 119837 FCFA ; les extrêmes ont été 17750 et 825750 FCFA et l'écart type de 174998 francs CFA. CONCLUSION: les infections associées aux soins restent fréquentes dans notre service et dominées par les infections du site opératoire. Les germes isolés étaient tous résistants dans 100% cas à l'Amoxicilline dans 88,88% cas à la Ciprofloxacine.
RESUMO
The trimellar pregnancy on bicicatricial uterus is a rare situation. It can be associated with many maternal-fetal complications. Given these risks, some teams opt for an embryonic reduction. We report a case of spontaneous trimellar pregnancy on bicicatricial uterus. This was a 38 year-old patient, third pregnancy, second birth, 2 alive with a history of 2 caesareans. The evolution of the pregnancy was marked by a urinary tract infection at 34 weeks of gestation. The caesarean section performed at 36 weeks of gestation allowed the birth of 3 newborns, 2 of which were females in 2000 and 1900 grams, and one male weighing 2400 grams. The postpartum was marked by a rapidly resolved eclampsia crisis.
La survenue d'une grossesse triméllaire sur un utérus bicicatriciel est une situation rare. Elle peut être associée à de nombreuses complications materno-fÅtales. Compte tenu de ces risques, certaines équipes optent pour une réduction embryonnaire. Nous rapportons un cas de grossesse triméllaire spontanée sur utérus bicicatriciel. Il s'agissait d'une patiente de 38 ans 3è geste, 2è pare avec 2 enfants vivants, ayant un antécédent de 2 césariennes. L'évolution de la grossesse a été marquée par une infection urinaire à 34 SA. La césarienne pratiquée à 36 SA a permit la naissance de 3 nouveaunés dont 2 de sexes féminins de 2000 et 1900g et un de sexe masculin pesant 2400g. Les suites de couches ont été marquées par une crise d'éclampsie rapidement résolue.
RESUMO
OBJECTIVE: The performance of colposcopy provided in a screening study in five African countries was evaluated. DESIGN: Cross-sectional study. SETTING: Burkina Faso, Congo Brazzaville, Guinea Conakry, Mali and Niger. POPULATION: Women aged 25-59 years. METHODS: A total of 29 294 women participated in a cervical screening study in the five study sites, and newly trained local doctors performed colposcopy and directed biopsies as indicated. Using meta-analytical tools, four measures of colposcopy performance at different thresholds of colposcopic abnormalities were assessed. Sources of heterogeneity were also assessed. MAIN OUTCOME MEASURES: Proportions of women receiving biopsies, adequate biopsies and women diagnosed with cervical intraepithelial neoplasia (CIN). RESULTS: Among 28 553 women with satisfactory colposcopy, 3101 had a colposcopic diagnosis of probable low-grade or worse lesions and 1128 probable high-grade or worse lesions. Overall, the measures that reached the set standards were proportion of biopsy taken at colposcopy threshold of probable high-grade or worse lesions (95%, 95% CI 90-100%) and proportion of adequate biopsy samples. The set standards were not met for the proportions of women diagnosed with CIN at different colposcopic abnormality thresholds. Detection of CIN2 or worse lesions increased with increasing colposcopic abnormality. CONCLUSIONS: The performance of colposcopy in some of the African sites studied was comparable to that previously observed in other studies. With appropriate training, monitoring, continuing practice and quality assurance, adequate standards of colposcopy can be attained in sub-Saharan Africa.

The aim of this work was to compare the prognosis of induced pregnancies and spontaneous pregnancies received in the service. PATIENTS AND METHODS: We performed a retrospective study of Ca / Witnesses (1 case for 2 controls) with age and parity matching. This study was conducted at the maternity ward of the Reference Health Center of Commune V District Bamako (CSREF CV) over a period of 10 years from January 1, 2007 to December 31, 2016 for all patients meeting our criteria of 'inclusion. We called cases, induced pregnancies, and witnessed spontaneous pregnancies. The data was entered and analyzed on the Epi-Info software version 6.04 according to the formula applicable to the Case / Witness study. RESULTS: We included in this study, (due to a case for two controls), 1611 induced pregnancies (cases), and 3222 spontaneous pregnancies (controls). The average age was 35.4 years (25 years-43 years) with an average parity of 2.7 (1-5). Hypertensive disorders, preterm birth, intrauterine growth retardation (IUGR), caesarean section, poor perinatal prognosis were found with a statistically significant difference (OR> 1) in patients with induced pregnancies. CONCLUSION: Induced singleton pregnancy is a high-risk pregnancy.
L'objectif de ce travail était de comparer le pronostic des grossesses induites et des grossesses spontanées reçues dans le service. PATIENTES ET MÉTHODES: Nous avons réalisé une étude rétrospective Ca/Témoins (1 Cas pour 2 Témoins) avec appariement de l'âge et la parité. Cette étude s'est déroulée la maternité du Centre de Santé de Référence de la Commune V du District de Bamako(CSREF CV) sur une période de 10ans allant du 1er janvier 2007 au 31 Décembre 2016 portant sur toutes les patientes répondant à nos critères d'inclusion. Nous avons appelé Cas, les grossesses induites et témoins les grossesses spontanées. Les données ont été saisies et analysées sur le logiciel Epi-Info version 6.04 conformément à la formule applicable à l'étude Cas/Témoins. RÉSULTATS: Nous avons inclus dans cette étude, (en raison d'un Cas pour deux Témoins), 1611 grossesses induites (Cas), et 3222 grossesses spontanées (Témoins). L'âge moyen était de 35,4 ans (25 ans-43ans) avec une parité moyenne de 2,7 (1-5). Les troubles hypertensifs, l'accouchement prématurité, le retard de croissance intra-utérin(RCIU), la césarienne, le mauvais pronostic périnatal ont été retrouvés avec une différence statistiquement significative (OR>1) chez les patientes avec grossesses induites. CONCLUSION: La grossesse singleton induite est une grossesse à haut risque.
RESUMO
The objectives of the work were to measure the degree of satisfaction of women in the postpartum period and to determine the stability of the immediate postpartum care satisfaction scale (PASS). MATERIAL AND METHOD: The motherhood of the reference health center of commune V served as a study framework. The study was descriptive for evaluative purposes in postpartum women. It covered the period from 11 July 2014 to 14 January 2015. Two interview questionnaires (SSOPPI1) and (SF12 and SSOPPI2) were used for data collection. The data analysis was done on the software EPI-info version 3.5.3. RESULTS: The study involved a total of 145 women in SSOPPI1 and SSOPPI2. The average age was 25.6 years ± 5.5 years. The level of satisfaction for the two phases of the study (SSOPPI1 and SSOPPI2) was a function of level of study, occupation, mode of initiation of labor, route of delivery, status of newborn at birth. Satisfaction was 98.6% in SSOPPI1 and was 98,5% in SSOPPI2 with a statistically insignificant difference (p = 0.67). CONCLUSION: The degree of overall satisfaction was a function of a number of factors. This satisfaction remained stable during both phases of the study.
Les objectifs du travail étaient de mesurer le degré de satisfaction des femmes dans le post-partum et de déterminer la stabilité de l'échelle de mesure de la satisfaction des soins post-partum immédiat(SSOPPI). MATÉRIEL ET MÉTHODE: La maternité du centre de santé de référence de la commune V a servi de cadre d'étude. L'étude était descriptive à visée évaluative portant sur les femmes en post-partum. Elle a couvert la période allant du 11juillet 2014 au 14 janvier 2015. Deux questionnaires d'entrevue (SSOPPI1) et (SF12 et SSOPPI2) ont été utilisés pour la collecte des données. L'analyse des données a été faite sur le logiciel EPI-info version 3.5.3. RÉSULTATS: L'étude a porté sur un total de 145 femmes en SSOPPI1 et SSOPPI2. L'âge moyen était de 25, 6ans±5,5ans. Le degré de satisfaction pour les deux phases de l'étude (SSOPPI1 et SSOPPI2) était fonction du niveau d'étude, la profession, le mode de déclenchement du travail, la voie d'accouchement, l'état du nouveau-né à la naissance. La satisfaction était de 98,6% en SSOPPI1 et de 98,5% en SSOPPI2 avec une différence statistiquement non significative (p=0,67). CONCLUSION: Le degré de satisfaction globale était fonction d'un certain nombre de facteurs. Cette satisfaction est restée stable pendant les deux phases de l'étude.
RESUMO
GOAL: The aim of this study was to compare the maternal-fetal prognosis of pregnancies at 40 years of age and above with that of pregnancies obtained before 40 years of age in the obstetric gynecology department of the reference health center of commune II of Bamako district. MATERIALS AND METHODS: This was a prospective cohort study that was conducted at the maternity ward of Reference Health Center of Commune II of Bamako district from 1st January to 31 December 2012. Were included in our study as patients exposed, all the pregnant women of 40 years and over and as unexposed patients, pregnant women aged 20-39 who gave birth in our service. Teenage pregnancies were not included in this study. The statistical tests used were Pearson's Khi2 and Fisher's test with a significance level of 5%. RESULTS: The frequency of pregnancy among women aged 40 and over was 1.68%. These were large multiparas unschooled patients in 60% of cases, with hypertension in 6.7% of cases. Pregnancy in her patients was associated with a high rate of caesarean section in 16.7% of cases, term overrun in 6.7% of cases, seat presentation in 6.7% of cases, macrosomia in 6.7% of cases and fetal malformation in 1.7% of cases. CONCLUSION: Slight account of its many maternal-fetal complications, pregnancies in women 40 years and older deserve special attention.
BUT: Le but de cette étude était de comparer le pronostic materno-foetal des grossesses chez les patientes de 40 ans et plus à celui des grossesses conçues avant 40 ans dans le service de gynécologie obstétrique du centre de santé de référence de la commune II de Bamako. MATÉRIELS ET MÉTHODES: Il s'agissait d'une étude prospective de Cohorte qui s'est déroulée à la maternité du Centre de Santé de Référence de la Commune II du 1er janvier au 31décembre 2012. Ont été incluses dans notre étude comme patientes exposées toutes les gestantes de 40 ans et plus et comme patientes non exposées les gestantes de 20-39 ans ayant accouchées dans notre service. N'ont pas été retenues dans cette étude, les grossesses chez les adolescentes. Les tests statistiques utilisés ont été le Khi2 de Pearson et le test de Fisher avec un seuil de significativité à 5%. RÉSULTATS: La fréquence de la grossesse chez les femmes de 40 ans et plus était de 1,68%. Il s'agissait de grandes multipares non scolarisées dans 60% des cas, présentant une HTA dans 6,7% des cas. La grossesse chez ces patientes a été associée à un taux élevé de césarienne dans 16,7% des cas, de dépassement de terme dans 6,7% des cas, de présentation du siège dans 6,7% des cas, de macrosomie dans 6,7% des cas et de malformation foetale dans 1,7% des cas. CONCLUSION: Compte ténu de ses nombreuses complications materno-foetales, les grossesses chez les femmes de 40 ans et plus méritent une attention particulière.
RESUMO
The high resistance to malaria in the nomadic Fulani population needs further understanding. The ability to cope with multiclonal Plasmodium falciparum infections was assessed in a cross-sectional survey in the Fulani and the Dogon, their sympatric ethnic group in Mali. The Fulani had lower parasite prevalence and densities and more prominent spleen enlargement. Spleen rates in children aged 2-9 years were 75% in the Fulani and 44% in the Dogon (P<0.001). There was no difference in number of P. falciparum genotypes, defined by merozoite surface protein 2 polymorphism, with mean values of 2.25 and 2.11 (P=0.503) in the Dogon and Fulani, respectively. Spleen rate increased with parasite prevalence, density and number of co-infecting clones in asymptomatic Dogon. Moreover, splenomegaly was increased in individuals with clinical malaria in the Dogon, odds ratio 3.67 (95% CI 1.65-8.15, P=0.003), but not found in the Fulani, 1.36 (95% CI 0.53-3.48, P=0.633). The more susceptible Dogon population thus appear to respond with pronounced spleen enlargement to asymptomatic multiclonal infections and acute disease whereas the Fulani have generally enlarged spleens already functional for protection. The results emphasize the importance of spleen function in protective immunity to the polymorphic malaria parasite.
