Abstract
BACKGROUND Onchocerciasis control activities in Mali began in 1975 with vector larviciding carried out by the Onchocerciasis Control Programme (OCP), followed by the distribution of ivermectin from 1998 until the closure of the OCP in 2002. At that time, epidemiological evaluations, using skin snip microscopy and O-150 pool screening PCR in black flies, indicated that the disease had been largely controlled as a public health problem. Ivermectin distribution was nevertheless continued after 2002 in 34 of the 75 health districts in Mali as these were known to still be meso- or hyper-endemic for onchocerciasis. In addition, the onchocerciasis sites known to be hypo-endemic for onchocerciasis benefited from the distribution of ivermectin treatment as part of the mass drug administration (MDA) program for lymphatic filariasis. Various entomological and epidemiological evaluations have now indicated that Mali may have achieved successful interruption of onchocerciasis transmission. METHODS A series of cross-sectional surveys to update vector breeding sites throughout the endemic areas, followed by a pre-stop ivermectin mass drug administration (Pre-stop MDA) survey, were undertaken in 2019-2020. Based on breeding site findings, historical epidemiological assessments, and vector collection site maps, 18 operational transmission zones (OTZ) were delineated within which a total of 104 first line villages were selected for evaluation. Dried blood spots (DBS) samples were collected from 10,400 children (5-9 years old) from these 104 first line villages and processed for the presence of OV16 antibody using a lab-based rapid diagnostic test. RESULTS Within the 544 Simulium damnosum s.l. breeding sites visited in all five endemic onchocerciasis endemic regions of Mali 18.01% (98/544) were seen to be active with the presence of at least one stage of S. damnosum. The overall prevalence of OV16 positive children was 0.45% (47/10,400). However, two hotspots were identified: 2.60% (13/500) seroprevalence in the OTZ number 5 in Kayes Region and 1.40% (7/500) in the OTZ number 1 of Sikasso Region. CONCLUSION These data show that onchocerciasis prevalence in the five endemic regions has declined to levels that indicate that Stop-MDA surveys should be now carried out in most of the OTZ except for one in the Kayes Region. This latter site will need additional ivermectin treatment before reevaluation, and an OTZ in the Sikasso Region requires revaluation before possibly reinitiating MDA.

Abstract
Lymphatic filariasis (LF) elimination activities started in Mali in 2005 in the most endemic areas and reached countrywide coverage in 2009. In 2004, the district of Bamako was endemic for LF with a prevalence of 1.5%. The current study was designed to determine LF endemicity level in the urban area of Bamako after three rounds of ivermectin and albendazole mass drug administration (MDA). A cross-sectional study was conducted in 2011 in Bamako city, consisting of human prevalence and entomological surveys. Volunteers aged 14 years and above were invited to participate and tested for evidence of Wuchereria bancrofti using night time blood thick smear microfilarial count and blood spots for LF antibodies using the SD BIOLINE Oncho/LF IgG4 Biplex rapid test (Ov16/Wb123). Mosquitoes were collected using CDC light and gravid traps and tested using molecular methods. Poolscreen software v2.0 was used to estimate vector transmission potential. Of the 899 volunteers, one (0.11%) was found to be positive for LF using the Oncho/LF IgG4 Biplex rapid test, and none was found to have Wuchereria bancrofti microfilariae. No mosquitoes were found infected among 6174 Culex spp. (85.2%), 16 Anopheles gambiae s.l. (An. gambiae s.l.) (0.2%), 26 Aedes spp. (0.4%), 858 Ceratopogonidae (11.8%) and 170 other insects not identified (2.3%) tested. Our data indicate that there was no active LF transmission in the low prevalence urban district of Bamako after three MDA rounds. These data helped the National LF programme move forward towards the elimination goal.

Abstract
There is a need for better tools to monitor the transmission of lymphatic filariasis and malaria in areas undergoing interventions to interrupt transmission. Therefore, mosquito collection methods other than human landing catch (HLC) are needed. This study aimed to compare the Ifakara tent trap type C (ITTC) and the Biogents sentinel trap (BGST) to the HLC in areas with different vector densities. Mosquitoes were collected in two villages in Mali from July to December in 2011 and 2012. The three methods were implemented at each site with one ITTC, one BGST, and one HLC unit that consisted of one room with two collectors-one indoor and the other outdoor. The Anopheles collected in 2011 were individually dissected, whereas those from 2012 were screened in pools using reverse transcription-polymerase chain reaction (RT-PCR) to determine the maximum infection prevalence likelihood (MIPL) for Wuchereria bancrofti and Plasmodium falciparum. The dissection of the females also allowed to assess the parity rates, as well its results. Over the 2 years, the HLC method collected 1,019 Anopheles, yields that were 34- and 1.5-fold higher than those with the BGST and ITTC, respectively. None of the dissected Anopheles were infected. The RT-PCR results showed comparable MIPL between HLC and ITTC for W. bancrofti with one infected pool from each trap's yield (respectively 0.03% [0.0009-0.2%] and 0.04% [0.001-0.2%]). For P. falciparum, no infected pool was recovered from BGST. The ITTC is a good alternative to HLC for xenomonitoring of program activities.

Abstract
In resource-limited countries, epilepsy prevalence is underestimated and little is known about its risk factors. Objectives: This study aimed to determine the prevalence and risk factors for epilepsy in six health districts (HD) in Mali. Methods A community-based cross-sectional and nested-case-control study was conducted in 180 villages with the highest number of suspicious epilepsy cases (SEC) in the six study HD. The SEC were observed as part of a Phase 1 screening conducted by community health workers (CHWs). For the nested case-control study, one case was matched with at least one control based on residence and age. A case of epilepsy was any person diagnosed with convulsive epilepsy after clinical assessment by a neurologist. A control was a person diagnosed as normal after neurological assessment by a neurologist. Data were collected on sociodemographic characteristics, familial and medical history of epilepsy, consanguinity, place of delivery, pre-term birth, length/type of delivery, and history of meningitis and cerebral malaria. A univariate and multivariate binomial logistic regression model was used to analyse factors associated with epilepsy. Results A total of 1,506 cases of epilepsy and 2,199 controls were enrolled in six HDs. The mean prevalence of epilepsy was 2‰, with the highest in Kenieba (3‰), a previously meso-endemic-onchocerciasis HD, and the lowest in Kadiolo (1.5‰), an hypo-endemic-onchocerciasis HD. Age [aOR=1.02 (95% CI 1.02-1.03)], history of cerebral malaria [aOR=11.41 (95% CI 8.86-14.85)], history of meningitis [aOR=1.95 (95% CI 1.16-3.29)], living in the HD of Tominian [aOR= 1.69 (95% CI 1.29-2.22)], delayed delivery [aOR= 3.21 (95% CI 2.07-5.07)] and dystocia [aOR= 3.37 (95% CI 2.03-5.73)] were all significantly associated with epilepsy. Discussion/Conclusion The prevalence of epilepsy (3‰) in a previously meso-endemic-onchocerciasis HD was much lower than the prevalence (13.35‰) documented in onchocerciasis endemic areas in 2000. This decrease epilepsy prevalence in the previously meso-endemic-region was induced by onchocerciasis and the reduction was due to an effective community direct treatment with ivermectin programme. Cerebral malaria and obstetrical complications were the main risk factors for epilepsy and interventions improving malaria prevention/treatment and optimising prenatal and obstetrical care need to be implemented to reduce incidence.

Abstract
BACKGROUND In 2004, Mali implemented mass drug administration (MDA) aimed at controlling schistosomiasis and soil-transmitted helminths. Despite several rounds of MDA, the health district of Bankass reported low coverage (64.8%) for praziquantel and albendazole in 2017, meaning that this district was still facing challenges in accomplishing the targeted 75% coverage. This study aimed to explore the barriers and gaps that hindered MDA implementation in Bankass. METHODS A cross-sectional study was performed. Questionnaires were administrated to all school-aged children in randomly selected villages. Technical directors of community health centers and community drug distributors in the selected villages were included in the interviews. RESULTS A total of 2128 children and 52 health workers were interviewed. Coverage rates were 93.51% (1990/2128) for praziquantel and 95.25% (2027/2128) for albendazole. Among the untreated children, 31.63% (31/98) reported being unaware of the campaign and 26.53% (26/98) were unable to reach the distribution points. Most of the health workers suggested increasing incentives. CONCLUSION The data showed satisfactory coverage >90%, in contrast with lower rates initially reported by the district health information system. These results raise concerns about the reliability of programmatic data and highlight the importance of population-based surveys for the evaluation of control interventions.

Abstract
BACKGROUND In Mali, cutaneous leishmaniasis (CL) and filariasis are co-endemic. Previous studies in animal models of infection have shown that sand fly saliva enhance infectivity of Leishmania parasites in naïve hosts while saliva-specific adaptive immune responses may protect against cutaneous and visceral leishmaniasis. In contrast, the human immune response to Phlebotomus duboscqi (Pd) saliva, the principal sand fly vector in Mali, was found to be dichotomously polarized with some individuals having a Th1-dominated response and others having a Th2-biased response. We hypothesized that co-infection with filarial parasites may be an underlying factor that modulates the immune response to Pd saliva in endemic regions. METHODOLOGY/PRINCIPAL FINDINGS To understand which cell types may be responsible for polarizing human responses to sand fly saliva, we investigated the effect of salivary glands (SG) of Pd on human monocytes. To this end, elutriated monocytes were cultured in vitro, alone, or with SG, microfilariae antigen (MF ag) of Brugia malayi, or LPS, a positive control. The mRNA expression of genes involved in inflammatory or regulatory responses was then measured as were cytokines and chemokines associated with these responses. Monocytes of individuals who were not exposed to sand fly bites (mainly North American controls) significantly upregulated the production of IL-6 and CCL4; cytokines that enhance leishmania parasite establishment, in response to SG from Pd or other vector species. This selective inflammatory response was lost in individuals that were exposed to sand fly bites which was not changed by co-infection with filarial parasites. Furthermore, infection with filarial parasites resulted in upregulation of CCL22, a type-2 associated chemokine, both at the mRNA levels and by its observed effect on the frequency of recruited monocytes. CONCLUSIONS/SIGNIFICANCE Together, our data suggest that SG or recombinant salivary proteins from Pd alter human monocyte function by upregulating selective inflammatory cytokines.

Abstract
BACKGROUND In Mali, the burden of epilepsy is underestimated due to socio-cultural barriers that keep most people with epilepsy out of the local health facilities. The objective of this study was to evaluate the performance of trained community health workers (CHWs) in identifying epilepsy cases (active case detection) as compared to the passive cases detection (PCD) during outpatient visits at the community health centers in the health districts (HDs) of Kolokani, Kayes, Kéniéba, Sikasso, Kadiolo, and Tominian. METHODS A two-phase cross-sectional study was conducted from February to December 2019. In phase 1, trained CHWs conducted a census in 1017 villages organized into 174 community health centers which are part of the six study HDs to identify suspected epilepsy cases (SEC). Investigators used a modified epilepsy screening questionnaire from a validated standard questionnaire with the following three (3) questions: (i) Does or did the subject have a loss of consciousness and/or a loss of urine and/or drooling? (ii) Does or did the subject have an uncontrollable shake or abnormal movements of limb(s) (convulsions), with sudden onset and duration of a few minutes? (iii) Has or had the subject ever been told that he or she has epilepsy? During phase 2, neurologists confirmed the supposedly SEC (censed by the CHWs) in the first 30 villages with the highest number of SEC in each HD that were reported during phase 1. RESULTS Of a total of 4830 SEC, 422 (10%) were identified by PCD during routine outpatient visits and 4408 (90%) through the active case detection (ACD) using the trained CHWs. The majority of SEC reported by the CHWs (PCD) were confirmed by neurologists, i.e. 82.9% (1645/1985). Phenobarbital was available in only 26 (14.9%) of the 174 surveyed health centers. Confirmed cases of epilepsy were reported in all the 174 health centers with prevalence varying from 91/100,00 to 285/100,000. CONCLUSION Active case detection of epilepsy using trained CHWs is an effective approach for epidemiological studies of epilepsy in the community settings as compared to the passive approach.

Abstract
Background In Mali, nomadic populations are spread over one third of the territory. Their lifestyle, characterized by constant mobility, excludes them from, or at best places them at the edge of, health delivery services. This study aimed to describe nomadic populations’ characteristics, determine their perception on the current health services, and identify issues associated with community-based health interventions. Methods To develop a better health policy and strategic approaches adapted to nomadic populations, we conducted a cross-sectional study in the region of Timbuktu to describe the difficulties in accessing health services. The study consisted in administering questionnaires to community members in the communes of Ber and Gossi, in the Timbuktu region, to understand their perceptions of health services delivery in their settings. Results We interviewed 520 individuals, all members of the nomadic communities of the two study communes. Their median age was 38 years old with extremes ranging from 18 to 86 years old. Their main activities were livestock breeding (27%), housekeeping (26.4%), local trading (11%), farming (6%) and artisans (5.5%). The average distance to the local health center was 40.94 km and 23.19 km respectively in Gossi and Ber. In terms of barriers to access to health care, participants complained mainly about the transportation options (79.4%), the quality of provided services (39.2%) and the high cost of available health services (35.7%). Additionally, more than a quarter of our participants stated that they would not allow themselves to be examined by a health care worker of the opposite gender. Conclusion This study shows that nomadic populations do not have access to community-based health interventions. A number of factors were revealed to be important barriers per these communities’ perception including the quality of services, poverty, lifestyle, gender and current health policy strategies in the region. To be successful, future interventions should take these factors into account by adapting policies and methods.

Abstract
INTRODUCTION The hematologic abnormalities constitute a reccuring problem in the general population. The HIV infection is a favourable situation for the potentiation of these various hematologic disorders. The aim of the study was to describe the quantitative and qualitative aspects of the three blood lines of our population of study. MATERIAL AND METHOD It was a prospective cross-sectional study of descriptive type having concerned the people received at the central laboratory of CHU de Yopougon for voluntary tracking from September 1st to September 30th, 2015. RESULTS We colliged 154 people among whom, a female prevalence was noted with a sex ratio M/F of 0.64. The age bracket from 18 to 29 years was represented (50%) with a 32.94 years median age ± 10 with the 18 and 75 years extremes represented by 50% of single people. The HIV infection prevalence was 20.37%. Anaemia was the most frequent hematologic abnormality (44.44%) its hypochromic microcitic form microcytic (50%) especially. The HIV positive patients had primarily a normochromic normocytic non regenerative anaemia (27.27%). Among HIV positive patients, 23 (65.22%) had a leuconeutropenia combined with lymphopenia at 23 (65.22%) and 12 had bicytopenia which consisted of thrombocytopenia and anaemia. A morphological abnormality of the three blood lines (red blood cells, white blood cells and platelets) was found in 57.41% of our subjects. CONCLUSION To be in apparent good health, does not exclude the hematologic abnormalities presence. But an HIV infection presence, even in the absence of specific treatment, increases the risk or the degree of severity of these different qualitative and quantitative abnormalities.

Abstract
INTRODUCTION Sleep disorders are diverse in Parkinson's disease. We aimed to assess the quality of sleep in patients with Parkinson's disease in an African population. METHODS In a transversal and prospective study from April to June 2014, all parkinsonian patients followed at the Fann Teaching Hospital Neurology Clinic (Dakar, Senegal) were assessed using the Hoehn and Yahr's scale and filled out the following questionnaires: Parkinson's disease sleep scale (PDSS), the Pittsburgh Sleep Quality Index (PSQI), and the Epworth Sleepiness Scale (ESS). A PDSS score<82 (or a subscore<5) and a PSQI score>5 indicated poor quality or impaired sleep. An ESS score>10 indicated excessive daytime sleepiness. We used the Pearson coefficient to search for correlation between age, disease stage, disease duration, and the importance of sleep impairment. RESULTS Hoehn and Yahr staging was 2.42±0.90 in the 35 patients (60% male, mean age 65.7±7.4years, disease duration 32.4±23.4months). The mean total PDSS score was 99.5±24.1 and 74.3% of the patients had an abnormally high PSQI score, indicating high frequency and intensity of sleep disorders. Most frequent disorders were pain or cramps interrupting sleep, night waking to urinate and fatigue or sleepiness on waking. Patients exhibited excessive diurnal sleepiness in 22.9% of the cases; they often had an abnormal PSQI score. Both the total PDSS score and the difficulty to sleep increased with disease stage, but not with age or disease duration. CONCLUSION We found evidence of major alteration of sleep quality in Senegalese Parkinson patients.

Abstract
OBJECTIVE Promote mobility between South-South and South-North for improving level of researchers, staff and students through a platform. METHODS The methodology is based a filling of a questionnaire about offer or demand. Material is composed a computer connected Internet. RESULT we registered about 203 demands and 31 offers from partners.43 mobilities were executed completely. CONCLUSION The results indicate a real need of mobility for researchers and health professionals in Africa. The important number of mobility demands made by external researchers and professionals (from outside the AFRICA BUILD Consortium) may be constrained by the difficulty to find adequate funding.

Abstract
Abstract. A total of 10,147 female goats from Burkina Faso were scored for 7 body measures and 12 qualitative traits. Sampling included the three main environmental areas and goat breeds of Burkina Faso: the Sahel area (Sahelian goat), the Sudan-Sahel area (Mossi goat) and the Sudan area (Djallonké goat). Overall, the Sahelian goat had the highest values for the all the analysed body measures. Differences between the Sudan and the Sudan-Sahel goat were little. The Burkina Faso goat is mainly spotted (61.92 %) with horns type “Spanish Ibex” (84.05 %), frequent absence of beard (75.33 %) and wattles (70.92 %) and poorly developed udder (73.72 %). The Sahelian population included most individuals with dropping (95.60 %) and curled (73.62 %) ears, whilst most Sudan-Sahel individuals had horizontal ears (73.14 %) and most Sudan individuals had vertical ears (97.88 %). The largest Mahalanobis distance was found between the Sahelian and Sudan areas (7.50) whilst the Sudan and the Sudan-Sahel populations were poorly differentiated (1.15). Discriminant analysis showed that most Sahel and Sudan-Sahel individuals were classified into their source population (79.29 % and 82.69 %) whilst the Sudan individuals (93.40 %) were classified as Sudan-Sahel individuals. Both the canonical and the correspondence analyses showed that the Sahelian and Sudan individuals tended to cluster separately whilst the Sudan-Sahel individuals showed an intermediate distribution but clearly biased toward the Sudan individuals. The Sudan-Sahel (Mossi) population can be considered a result from the genetic contact between Sahelians and Sudan goats.

Abstract
We report a rare case of ovarian fibroma in a young woman. When ovarian masse is associated with Meigs' syndrome and elevated CA 125 serum level a malignant process may be suspected. But a negative cytological examination of ascitic effusion and absence of peritoneal implant recommend performing limited surgical procedures.

Abstract
Infections represents 5% of our post-operative morbidity and result in the use of expensive antibiotics and longer hospital stays. As a less expensive alternative to systematic antibiotherapy for all patients, the authors propose a prospective and descriptive study of the effectiveness of antibioprophylaxis by administering 1 g of Cefotaxime pre-operatively. The study concerns a continuous series of 103 cases in gynaecology and obstetrics operated in the Dakar University Teaching Hospital, during a 13 months period (April 95-April 96). The average age of the patients is 30 years, the major types of surgery was cesarean sections, laparotomy for extra-uterine pregnancy and myomectomies. The duration of the surgery varied between 40 to 105 minutes with an average of 60 minutes. There was no intolerance to Cefotaxime. No cases of post operative infections were observed. All surgical wounds healed in 6 to 8 days except 2 minor cases of non-union of 1 cm. Antibioprophylaxis with Cefotaxime can therefore be considered as an effective means of preventing post-operative infections in clean surgery. It is easy to administer and also has the advantage of lower cost (4050 Fcfa compared to 29,000 Fcfa for classic antibiotherapy).

Abstract
Hysterectomy on pregnant uterus is a mutilating procedure used by obstetrician only when he haven't choice in case of major complications of pregnancy or delivery. This retrospective study worked on 35 cases of obstetrical hysterectomy performed on 22 months period (January 94-October 95). The frequency of the procedure among all the in hospital deliveries was 0.45%. The mean age of the patients was 31 years, and the mean parity was 7. 77.5% of the women were referred from over surrounding hospitals where natural deliveries had failed. We performed the hysterectomy because of uncontrolled haemorrhage in 71.7%, and infection in 25.8%. Sub-total hysterectomy was performed in 82.8%. Maternal mortality was 20%. Hysterectomy is very mutilating, but is a life rescueing procedure behind a lifethreatening complication of pregnancy or delivery. The best strategy to prevent the necessity of hysterectomy, is to develop the early obstetrical reference program that unfortunately is not yet in practice in our health care system.

Abstract
Granulated polyamide (PA) was tested for use as an external marker to estimate faecal DM (FDM) excretion of Zebu cattle (Bos indicus). The study was conducted in Mali, using seven and eighteen animals respectively in four field trials and six indoor experiments. Cattle ate fresh or dry pasture vegetation and half the animals were additionally supplemented with crop byproducts. Gelatine capsules containing 35, 40 or 45 g PA were administered orally at 12 h intervals. Estimates of FDM were based on the average marker concentration in faeces and were correlated with the actual excretion measured by total faecal collection. The pre-measurement period required to establish equilibrium for regular marker dosing was determined at 4 d. Except for diets with a N content of less than 9.26 g/kg organic matter, marker recovery averaged 98.1 (SE 0.93)% (n 62), and was not influenced by diet composition and the quantity of feed ingested (P > 0.05). Estimates of FDM based on average PA concentrations in faecal samples were correlated to the actual excretion with r 0.98 (n 62; P < or = 0.001). Since the PA concentration in individual faecal grab-samples is not correlated with either sample mass or sampling time, accurate estimates of FDM require a grab-sampling schedule that covers the 24 h day. However, estimates of FDM were found to be acceptable if calculations are based on the average PA concentration in the sub-total of samples collected during the day or during night respectively (r 0.95, n 29; P < or = 0.001 in both cases). It is concluded that the use of PA marker is a simple and inexpensive method resulting in reliable estimates of FDM. Since sophisticated analytical procedures are not required to recover PA in faecal samples, the marker is particularly suitable for application in extensive grazing systems and in studies conducted in less-developed countries.

Abstract
Pupae and teneral flies of Glossina palpalis gambiensis originating from three successive reproductive cycles were compared for their size and weight. In general, pupal weight and fly weight increased, whereas fly size, measured as wing vein length, decreased with the number of reproductive cycles. The linear regression observed between weight and wing vein length of the fly demonstrated that, particularly for flies originating from the first and second larvipositions, small changes in wing vein length reflected substantial differences in weight. The results of these laboratory experiments were compared with some field data on Glossina morsitans from Zambia and related literature. The life span of the female tsetse, affecting the size of her progeny, could clarify partially some of the field observed seasonal changes in size, whereas the correlation between fly size and weight could eventually explain the differential mortality of some size classes of tsetse flies. However, whether these laboratory observations can be extrapolated to the field has still to be confirmed.

Abstract
Sexual assaults constitute a prominent fact of our societies to this end twentieth Century. Then its's very important for physicians to be informed about obstacles encoured to manage assaults victims. Our study presents 25 cases of sexual assaults listed in Obstetrics and Gynecology Clinics of University Center Hospital of Dakar. It works out that: there are adolescents in most cases (85%); delay of examination is too long (11 cases beyond 24 hours) and compromises cytologic exams; injuries evaluation is sometimes negative; no lesion of anal sodomy is found. The authors insist to provide more informations to physicians to overcome evaluation of assault victim which has an impact for legal proceeding against offender. They call gaps to fill up un senegalese jurisprudence about assault victim who gets an accidental pregnancy.
