Abstract
INTRODUCTION In 2020, an estimated 150 million children under the age of 5 years were stunted. Stunting results from early-life adversity and it is associated with significant physical and cognitive deficit, lifelong socioeconomic disadvantage and reduced life expectancy. There is a need to understand the causes of stunting and its effects in order to develop strategies to avoid it and to mitigate the consequences once stunting has occurred. Epigenetics is an important mechanism through which early-life factors are thought to influence biological function, with long-term consequences. We describe a series of epigenetic studies designed to understand how early-life adversity results in stunting and to inform the development of practical tools such as predictive markers and therapeutic targets. This work is part of the UKRI GCRF Action Against Stunting Hub. METHODS AND ANALYSIS The project-in India, Indonesia and Senegal-comprises an observational study of mothers, fathers, and offspring (n=500) spanning the first 1000 days of life, and an intervention study in each country. Epigenetic status (DNA methylation) is determined in saliva from babies collected within 1 month of birth and again at 18 months of age, and from mothers and fathers around the time of birth. Epigenome-wide analysis is carried out using the Illumina EPIC array, augmented by high-definition sequencing approaches. Statistical analysis is carried out at the level of candidate genes/regions, higher dimensional epigenetic states and epigenome-wide association. Data analysis focuses on the determinants of stunting, the effectiveness of interventions, population comparisons and the link between epigenetics and other thematic areas, which include anthropometry, microbiome, gut health, parasitology, cognition, nutrition, food hygiene and water sanitation, food systems and the home environment. ETHICS AND DISSEMINATION This study has been approved by the relevant Ethics Committees in Indonesia, India and Senegal, and the UK. Research data will be published and posted in public repositories.

Abstract
Despite marked progress in Senegal, three regions in the southeast part continue to have a high burden of malaria, but there have been no recent studies assessing the prevalence of malaria associated with pregnancy. This study aimed to determine the prevalence of malaria infection in pregnant women attending antenatal clinics in Senegal. During the malaria transmission season of 2019, pregnant women attending 11 health care facilities for a scheduled visit and those presenting unwell with signs of malaria were invited to participate in a malaria screening study. A finger prick blood sample was taken for malaria diagnosis by rapid diagnosis test (RDT) and polymerase chain reaction (PCR). A total of 877 pregnant women were enrolled, 787 for a scheduled antenatal consultation and 90 for an unscheduled consultation with signs of malaria. The prevalence of Plasmodium falciparum among the first group was 48% by PCR and 20% by RDT, and that among the second group was 86% by PCR and 83% by RDT. RDT sensitivity in capturing asymptomatic, PCR-positive infections was 9.2% but ranged from 83% to 94% among febrile women. The prevalence of infection by PCR in women who reported having received at least three doses of sulfadoxine pyrimethamine (SP) was 41.9% compared with 58.9% in women who reported they had not received any SP doses (prevalence ratio adjusted for gravidity and gestational age, 0.54; 95% CI, 0.41-0.73). The burden of P. falciparum infections remains high among pregnant women, the majority of which are not captured by RDT. More effective measures to prevent malaria infection in pregnancy are needed.

Abstract
Female genital schistosomiasis (FGS) caused by Schistosoma haematobium is a neglected chronic parasitic disease. Diagnosis relies mainly on a colposcopy, which reveals non-specific lesions. This study aimed to assess the performance of two sampling methods for the molecular diagnosis of FGS in the uterine cervix. We conducted a descriptive cross-sectional study in women of reproductive age in Saint Louis, Senegal, who presented for cervical cancer screening. Cotton swab and cytobrush samples were collected from the cervix and examined by real-time PCR. The PCR results obtained using the cotton swabs were compared with those obtained using cytobrush. Of the 189 women recruited, 56 (30%) were found to be positive for S. haematobium infection via real-time PCR. Women aged 40-54 years were predominantly infected (45%) followed by those aged 25-39 years (36%). Numerically more PCR-positive specimens were identified using cytobrush sampling. Of the 89 women who underwent both cytobrush and cotton swab sampling, 27 were PCR-positive in the cytobrush sampling vs 4 in the swab sampling. The mean Ct-value was 31.0 ± 3.8 for cytobrush-based PCR vs 30.0 ± 4.4 for swab-based PCR. The results confirm that real-time PCR can detect Schistosoma haematobium DNA in the uterine cervix. The next step will be to compare PCR with the other diagnostic methods of FGS.

Abstract
Visceral leishmaniasis (VL) is an infectious disease caused by protozoa of the genus Leishmania. Sporadic cases are observed in nonendemic areas and often associated with limited foci; therefore, the disease is easily overlooked. In addition, other diseases have similar clinical symptoms, which make it difficult for clinicians to make an accurate diagnosis and to provide effective treatment. We identified visceral leishmaniasis in a 4-year-old child in Pikine, Senegal. The patient was admitted to the Pikine National Teaching Hospital for haemorrhagic, tumoral, and infectious syndromes. At admission, the patient presented with epistaxis and gingivorrhagia, a severe anaemic syndrome poorly tolerated, a systemic inflammatory response syndrome with fever at 39.5°C, a tumoral syndrome with 11 cm of hepatomegaly and 12 cm of type IV splenomegaly, and noninflammatory macropoly adenopathies. A spinal cord puncture was performed, and direct microscopy examination of the sample after GIEMSA staining revealed amastigote forms of Leishmania. The PCR amplification of extracted DNA from the bone marrow aspiration using specific primers for VL (forward and reverse) confirmed that VL was responsible for the infection. A treatment with meglumine antimoniate (Glucantime) was given and it gave a successful outcome with remission of clinical symptoms and favourable evolution with 3 months hindsight. Conclusion. This visceral leishmaniasis case diagnosis in Senegal has shown that, apart from haematological malignancies, this disease must be considered in combination with a tumor syndrome, haemorrhagic syndrome, and infectious syndrome.

Abstract
Background: Seasonal malaria chemoprevention (SMC) with sulfadoxine-pyrimethamine plus amodiaquine (SPAQ) is a malaria prevention strategy recommended since 2012 by the World Health Organization (WHO) for children under 5 years. In Senegal, the scaling up of SMC started in 2013 in the south-eastern regions of the country with an extension of the target to 10 years old children. The scaling up of SMC requires regular evaluation of the strategy as recommended by the WHO. This study was conducted to evaluate the effectiveness of SMC. Methods: A case-control study was conducted in some villages of the health districts of Saraya and Kedougou in the Kedougou region from July to December 2016. A case was a sick child, aged 3 months to 10 years, seen in consultation and with a positive malaria rapid diagnostic test (RDT). The control was a child of the same age group with a negative RDT and living in the same compound as the case or in a neighbouring compound. Each case was matched with two controls. Exposure to SMC was assessed by interviewing the mothers/caretakers and by checking the SMC administration card. Results: Overall, 492 children, including 164 cases and 328 controls, were recruited in our study. Their mean ages were 5.32 (+/- 2.15) and 4.44 (+/-2.25) years for cases and controls, respectively. The number of boys was higher in both cases (55.49%; CI 95%=47.54-63.24%) and controls (51,22%; CI 95%=45.83-56.58%). Net ownership was 85.80% among cases and 90.85% among controls (p=0,053). The proportion of controls who received SMC was higher than that of cases (98.17% vs 85.98% and p=1.10 -7). The protective effectiveness of SMC was 89% (OR= 0.12 (CI 95%=0.04-0.28)). Conclusions: SMC is an effective strategy in the control of malaria in children. Case-control studies are a good approach for monitoring the efficacy of drugs administered during SMC.

Abstract
BACKGROUND A post-acne hyperpigmentation index (PAHPI) has been developed in the United States to better compare therapeutic modalities. Our aim in this study was to validate the PAHPI score in patients with skin type VI from sub-Saharan Africa. PATIENTS AND METHODS The study was conducted in Dakar, Senegal. Twenty-one patients with Fitzpatrick skin type VI, aged 17 to 55 years, presenting hyperpigmentation secondary to acne were included. Ongoing use of skin bleaching products or acne treatments was allowed. Four trained dermatologists rated the patients using the PAHPI. A narrow-band reflectance spectrophotometer (Mexameter MX-18, Cologne, Germany) was used to measure the degree of pigmentation of involved and adjacent skin on 6 representative facial lesions. RESULTS The average inter-rater reliability (weighted Kappa) showed substantial agreement for intensity (0.67), moderate agreement for number (0.53) and fair agreement for lesion size (0.28). Inter-rater reliability for the total PAHPI was excellent for both day 1 and day 2 (interclass correlation coefficient of 0.87 and 0.85, respectively; P<0.0001). Intra-rater reliability for total PAHPI ranged from 0.83 to 0.93 (P<0.0001). PAHPI scoring thus demonstrated excellent reliability both between and within raters. The association was moderate to substantial for all raters on both days (range for rho on day 1: 0.531 to 0.815; range for rho on day 2: 0.448 0.762). The correlations between the Mexameter (Courage and Khazaka) measurements and PAHPI scores showed moderate to substantial agreement. CONCLUSION Although tested primarily in African American women to date, PAHPI is also valid for patients from sub-Saharan Africa.

Abstract
Background : Seasonal malaria chemoprevention (SMC) has been adopted and implemented in the southern regions of Senegal in children aged between three and 120 months since 2013. Scaling up this strategy requires its evaluation to assess the impact. This study was carried out to determine the dynamics of Plasmodium falciparum carriage before and after two years of SMC implementation. Methods : Four household surveys were conducted in villages in the health district of Saraya, which is a SMC implementation area in Senegal. These villages were selected using probability proportional to size sampling. Each selected village was divided into segments containing at least 50 children. In each segment, a household questionnaire was administered to the parents or legal representatives of children aged three to 120 months. Blood smears were collected to determine P. falciparum prevalence by microscopy one month before the first round of SMC, one month after the last round of the first SMC campaign and two years after the start of the implementation. Results : A total of 2008 children were included with a mean average age of 4.81 (+/-2.73) years. Of the study population, 50.33% were more than five years old and 50.3% were male. In 2013, mosquito net ownership was 99.4 % before the SMC campaign and 97.4% after. In 2015, it was 36.6% before and 45.8% after the campaign. In 2013, the prevalence of plasmodium carriage was 11.8% before and 6.1% after the SMC campaign. In 2015, the prevalence was 4.9% before the administration of SMC and this increased up to 15.3% after. Malaria prevalence was high among children over five years old and in boys. Conclusions : The decrease in Plasmodium falciparum parasite prevalence, which subsequently increased after two years of SMC implementation in this study, suggests adding an extra cycle of the SMC or adjusting the administration period.

Abstract
Background: Seasonal malaria chemoprevention (SMC) with sulfadoxine-pyrimethamine plus amodiaquine (SPAQ) is a malaria prevention strategy recommended since 2012 by the World Health Organization (WHO) for children under 5 years. In Senegal, the scaling up of SMC started in 2013 in the south-eastern regions of the country with an extension of the target to 10 years old children. The scaling up of SMC requires regular evaluation of the strategy as recommended by the WHO. This study was conducted to evaluate the effectiveness of SMC. Methods: A case-control study was conducted in some villages of the health districts of Saraya and Kedougou in the Kedougou region from July to December 2016. A case was a sick child, aged 3 months to 10 years, seen in consultation and with a positive malaria rapid diagnostic test (RDT). The control was a child of the same age group with a negative RDT and living in the same compound as the case or in a neighbouring compound. Each case was matched with two controls. Exposure to SMC was assessed by interviewing the mothers/caretakers and by checking the SMC administration card. Results: Overall, 492 children, including 164 cases and 328 controls, were recruited in our study. Their mean ages were 5.32 (+/- 2.15) and 4.44 (+/-2.25) years for cases and controls, respectively. The number of boys was higher in both cases (55.49%; CI 95%=47.54-63.24%) and controls (51,22%; CI 95%=45.83-56.58%). Net ownership was 85.80% among cases and 90.85% among controls (p=0,053). The proportion of controls who received SMC was higher than that of cases (98.17% vs 85.98% and p=1.10-7). The protective effectiveness of SMC was 89% (OR= 0.12 (CI 95%=0.04-0.28)). Conclusions: SMC is an effective strategy in the control of malaria in children. Case-control studies are a good approach for monitoring the efficacy of drugs administered during SMC.

Abstract
INTRODUCTION Urachus is an embryonic remnant that usually involutes before birth. Abnormal persistence of this structure gives embryologic malformation like an urachal cyst. Infection or malignancy degeneration can complicated it. CASE PRESENTATION Case 1: We report 20 years old female patient consulted with acute abdominal pain. Clinical examination showed fever and infra-umbilical tender mass. The abdominal Computerized Tomography showed pelvic mass between umbilicus and bladder. The open laparotomy found infra-abdominal semi-solid mass. A complete resection was done and histological exam confirmed infected urachal cyst. Case 2: A 19 years old male patient presented with abdominal pain and fever. Physical examination found tenderness in lower abdomen. Biology revealed leukocytosis, and Ultrasonography found a heterogeneous infra-umbilical mass. Surgical exploration by mini-laparotomy found an abscess urachal cyst that is confirm by histological exam after complete resection. CLINICAL DISCUSSION Urachal cyst in adult patient is rare. Clinical symptoms without complications are insignificant. Because of malignancy risk, adult urachal cyst are managed by surgery. CONCLUSION Infection cyst is the most common complication of urachal cyst. Complete resection is recommended because of malignancy degeneration risk.

Abstract
Background: Seasonal malaria chemoprevention (SMC) has been adopted and implemented in the southern regions of Senegal in children aged between three and 120 months since 2013. Scaling up this strategy requires its evaluation to assess the impact. This study was carried out to determine the dynamics of Plasmodium falciparum carriage before and after two years of SMC implementation. Methods: Four household surveys were conducted in villages in the health district of Saraya, which is a SMC implementation area in Senegal. These villages were selected using probability proportional to size sampling. Each selected village was divided into segments containing at least 50 children. In each segment, a household questionnaire was administered to the parents or legal representatives of children aged three to 120 months. Blood smears were collected to determine P. falciparum prevalence by microscopy one month before the first round of SMC, one month after the last round of the first SMC campaign and two years after the start of the implementation. Results: A total of 2008 children were included with a mean average age of 4.81 (+/-2.73) years. Of the study population, 50.33% were more than five years old and 50.3% were male. In 2013, mosquito net ownership was 99.4 % before the SMC campaign and 97.4% after. In 2015, it was 36.6% before and 45.8% after the campaign. In 2013, the prevalence of plasmodium carriage was 11.8% before and 6.1% after the SMC campaign. In 2015, the prevalence was 4.9% before the administration of SMC and this increased up to 15.3% after. Malaria prevalence was high among children over five years old and in boys. Conclusions: The decrease in Plasmodium falciparum parasite prevalence, which subsequently increased after two years of SMC implementation in this study, suggests adding an extra cycle of the SMC or adjusting the administration period.

Abstract
BACKGROUND In Senegal, malaria morbidity has sharply decreased over these past years. However, malaria epidemiology remains heterogeneous with persistent transmission in the southeastern part of the country and many cases among older children and adolescents. Little is known about factors associated with clinical malaria among this group. A better understanding of malaria transmission among this newly emerging vulnerable group will guide future interventions targeting this population group. This study aimed to identify factors associated with clinical malaria among adolescents in Senegal. METHODS A case-control study was conducted from November to December 2020 in four health posts located in the Saraya district. Cases were defined as adolescents (10-19 years) with an uncomplicated malaria episode with fever (temperature > 37.5°) or a history of fever and positive malaria rapid diagnostic test (RDT). Controls were from the same age group, living in the neighbourhood of the case, presenting a negative RDT. A standardized, pre-tested questionnaire was administered to each study participant followed by a home visit to assess the participant's living conditions. Factors associated with clinical malaria were assessed using stepwise logistic regression analysis. RESULTS In total, 492 individuals were recruited (246 cases and 246 controls). In a multivariate analysis, factors associated with clinical malaria included non-use of long-lasting insecticidal net (LLIN) (aOR = 2.65; 95% CI 1.58-4.45), non-use of other preventive measures (aOR = 2.51; 95% CI 1.53-4.11) and indoor sleeping (aOR = 3.22; 95% CI 1.66-6.23). Protective factors included 15-19 years of age (aOR = 0.38; 95% CI 0.23-0.62), absence of stagnant water around the house (aOR = 0.27; 95% CI 0.16-0.44), having a female as head of household (aOR = 0.47; 95% CI 0.25-0.90), occupation such as apprentice (OR = 0.24; 95% CI 0.11-0.52). CONCLUSIONS The study revealed that environmental factors and non-use of malaria preventive measures are the main determinants of malaria transmission among adolescents living in areas with persistent malaria transmission in Senegal. Strategies aimed at improving disease awareness and access to healthcare interventions, such as LLINs, are needed to improve malaria control and prevention among these vulnerable groups.

Abstract
BACKGROUND Microscopic examination of Giemsa-stained blood films remains the reference standard for malaria parasite detection and quantification, but is undermined by difficulties in ensuring high-quality manual reading and inter-reader reliability. Automated parasite detection and quantification may address this issue. METHODS A multi-centre, observational study was conducted during 2018 and 2019 at 11 sites to assess the performance of the EasyScan Go, a microscopy device employing machine-learning-based image analysis. Sensitivity, specificity, accuracy of species detection and parasite density estimation were assessed with expert microscopy as the reference. Intra- and inter-device reliability of the device was also evaluated by comparing results from repeat reads on the same and two different devices. This study has been reported in accordance with the Standards for Reporting Diagnostic accuracy studies (STARD) checklist. RESULTS In total, 2250 Giemsa-stained blood films were prepared and read independently by expert microscopists and the EasyScan Go device. The diagnostic sensitivity of EasyScan Go was 91.1% (95% CI 88.9-92.7), and specificity 75.6% (95% CI 73.1-78.0). With good quality slides sensitivity was similar (89.1%, 95%CI 86.2-91.5), but specificity increased to 85.1% (95%CI 82.6-87.4). Sensitivity increased with parasitaemia rising from 57% at < 200 parasite/µL, to ≥ 90% at > 200-200,000 parasite/µL. Species were identified accurately in 93% of Plasmodium falciparum samples (kappa = 0.76, 95% CI 0.69-0.83), and in 92% of Plasmodium vivax samples (kappa = 0.73, 95% CI 0.66-0.80). Parasite density estimates by the EasyScan Go were within ± 25% of the microscopic reference counts in 23% of slides. CONCLUSIONS The performance of the EasyScan Go in parasite detection and species identification accuracy fulfil WHO-TDR Research Malaria Microscopy competence level 2 criteria. In terms of parasite quantification and false positive rate, it meets the level 4 WHO-TDR Research Malaria Microscopy criteria. All performance parameters were significantly affected by slide quality. Further software improvement is required to improve sensitivity at low parasitaemia and parasite density estimations. Trial registration ClinicalTrials.gov number NCT03512678.

Abstract
PURPOSE To describe the repercussions of teleworking among the employees of an humanitarian agency based in Dakar, in the context of the Covid-19 pandemic. MATERIAL AND METHODS We carried out a transversal, descriptive study, from june 10 to 13, 2021. An anonymous online questionnaire, created via Google Survey platform, was sent to the various employees of this agency. RESULTS Married people were more numerous (76%). The average age was 45.7 yearsold. The employees lived in families of an average of six peoples. The most enumerated advantages of teleworking were the economic gains linked to the absence of travel (88%), the improvement of work / family balance (84%), the increase in efficiency (64%) and feeling of freedom felt (56%). On the other hand, the increase in working time (96%), low back pain (72%), the family environment often not very favorable to teleworking (52%) and the decrease in social ties between colleagues (60%) were the main limitations of teleworking. CONCLUSION It has many advantages and also has limitations. These could be minimized by better organization and psychological support for the staff.

Abstract
OBJECTIVES to determine the mechanisms, lesions and hospital management of work-related accidentduringtraditional fishing,an activity subject to vital occupational risks. MATERIALS AND METHODS Descriptive retrospective study on occupational injury files in artisanal fishing professions, registered at the Saint-Louis Regional Hospital (Senegal), from January 2014 to December 2019. All complete records of trauma during any activity related to artisanal fishingwereincluded. Data on accident mechanisms, injuries observed, and hospital management were collected. RESULTS 47 male workers were on average 28.4 years old. Direct shock from a pirogue was most frequent (68.10%), followed by sharp or blunt objects (16.27%). The lesions were characterized by bone fractures in 63.83% of cases (n=30); chest-abdominal-pelvic and limb contusions and wounds represented 12.67% and 21.27% of cases, respectively. Medical management was done in 21 cases (44.7%). Surgery was dominated by intramedullary nailing in 15 cases (31.9%). Two laparotomies were performed with intestinal sutures. A chest contusion death was reported. CONCLUSION Traumatic occupational risks in traditional fishing are life threatening. A better understanding of these risks and their consequencesmakes it possible to ensure good prevention.

Abstract
INTRODUCTION The Richard-Toll social security fund agency ranks second in terms of declaration of work accidents (WA) in Senegal. In view of this and in the absence of a study that is interested in this subject, we initiated this work, the aim of which was to study these WA declared in the said agency. METHODOLOGY This was a retrospective and descriptive study carried out from January 1, 2018 to December 31, 2020. The parameters studied were the socio-professional information of the victims and the characteristics of the accidents. RESULTS A total of 1,071 workplace accidents were recorded. The average age of the victims was 37.1 years old. Agricultural workers and laborers were more concerned (95.5%). Site accidents accounted for 95% of cases. Lesions were mainly wounds (83.3%) and were benign in 98.2% of cases. The machete was incriminated in 48.5% of cases. Accidents occurred while cutting sugar cane in 81% of cases. The Senegalese sugar company was the main reporter (99%) and 84.4% of accidents were recorded periodically from December to May. CONCLUSION Work accidents are a reality in the Senegalese sugar company. Studies are urgently needed to better understand this issue. The purpose was to strengthen pre-existing prevention programs.

Abstract
Intracerebral hemorrhage accounts for approximately 15% of the 115,000 strokes occurring each year in France. Although therapeutic strategies are more limited than for ischemic stroke, major points in the management of intracerebral hemorrhage can reduce short term morbidity and mortality by limiting the expansion of the hematoma and the occurrence of early complications, and long term patients' outcome by reducing the risk of recurrence. This article aims to update the key elements that contribute to improve of the prognosis of intracerebral hemorrhage patients.

Abstract
Ischemic stroke accounts for 80% of overall stroke, and is one of the leading causes of death, disability and dementia in worldwide. Management of patients with acute ischemic stroke dramatically improved over time with the implementation of intensive care stroke units, the development of acute recanalization strategies, the optimization of the management of post-stroke complications, and the prevention of early stroke recurrence. The objective of this article is to provide a general overview of the current management of patients with acute ischemic stroke aiming at improving post-stroke outcome.

Abstract
The emergence of artemisinin-resistant Plasmodium falciparum parasites in Southeast Asia threatens malaria control and elimination. The interconnectedness of parasite populations may be essential to monitor the spread of resistance. Combining a published barcoding system of geographically restricted single-nucleotide polymorphisms (SNPs), mainly mitochondria of P. falciparum with SNPs in the K13 artemisinin resistance marker, could elucidate the parasite population structure and provide insight regarding the spread of drug resistance. We explored the diversity of mitochondrial SNPs (bp position 611-2825) and identified K13 SNPs from malaria patients in the districts of India (Ranchi), Tanzania (Korogwe), and Senegal (Podor, Richard Toll, Kaolack, and Ndoffane). DNA was amplified using a nested PCR and Sanger-sequenced. Overall, 199 K13 sequences (India: N = 92; Tanzania: N = 48; Senegal: N = 59) and 237 mitochondrial sequences (India: N = 93; Tanzania: N = 48; Senegal: N = 96) were generated. SNPs were identified by comparisons with reference genomes. We detected previously reported geographically restricted mitochondrial SNPs (T2175C and G1367A) as markers for parasites originating from the Indian subcontinent and several geographically unrestricted mitochondrial SNPs. Combining haplotypes with published P. falciparum mitochondrial genome data suggested possible regional differences within India. All three countries had G1692A, but Tanzanian and Senegalese SNPs were well-differentiated. Some mitochondrial SNPs are reported here for the first time. Four nonsynonymous K13 SNPs were detected: K189T (India, Tanzania, Senegal); A175T (Tanzania); and A174V and R255K (Senegal). This study supports the use of mitochondrial SNPs to determine the origin of the parasite and suggests that the P. falciparum populations studied were susceptible to artemisinin during sampling because all K13 SNPs observed were outside the propeller domain for artemisinin resistance.

Abstract
Stroke in women may be considered as a distinct entity due to numerous differences compared with men, including specific epidemiological, etiological, and outcome features along with unique pathophysiological mechanisms. Stroke is the second cause of death in women worldwide with sex-specific causes of stroke in youger women such as pregnancy, post-partum period, oral contraception and migraine. Substitutive hormone treatment in older women is no more recommended in regard of the increased thromboembolic risk it generates. Venous thrombolysis with rtPA and mechanical thrombectomy are now proven to be as efficacious in women as in men. After a stroke, women present poorer quality of life than men attributable to age, more severe stroke, pre-stroke dependency and depression. Recent data concerning the latest epidemiological surveys reveal a shift in trends with the rise of incidence of strokes in young women (≤55 years and 64 years) contrasting with the stability of incidence rates in older women. As science is unvealing sex-related differences in cardiovascular disorders, health policies need to be adapted accordingly to improve stroke prevention and pre-stroke health in women. In the meantime, therapeutical trials should include more women in order to be able to formulate adequate management.

Abstract
In the central western Senegal, malaria transmission has been reduced low due to the combination of several effective control interventions. However, despite this encouraging achievement, residual malaria transmission still occurring in few areas, mainly ensured by An. arabiensis and An. melas. The resurgence or the persistence of the disease may have originated from the increase and the spread of insecticide resistance genes among natural malaria vectors populations. Therefore, assessing the status and mechanisms of insecticides resistance among targeted malaria vectors is of highest importance to better characterize factors underlying the residual transmission where it occurs. Malaria vectors were collected from three selected villages using nocturnal human landing catches (HLC) and pyrethrum spray collections (PSC) methods. An. gambiae s.l. specimens were identified at the species level then genotyped for the presence of kdr-west (L1014F), kdr-east (L1014S) and ace-1R mutations by qPCR. An. arabiensis (69.36%) and An. melas (27.99%) were the most common species of the Gambiae complex in the study area. Among An. arabiensis population, the allelic frequency of the kdr-east (22.66%) was relatively higher than for kdr-west mutation (9.96%). While for An. melas populations, the overall frequencies of both mutations were very low, being respectively 1.12% and 0.40% for the L1014S and L1014F mutations. With a global frequency of 2%, only the heterozygous form of the G119S mutation was found only in An. arabiensis and in all the study sites. The widespread occurrence of the kdr mutation in both An. arabiensis and An. melas natural populations, respectively the main and focal vectors in the central-western Senegal, may have contributed to maintaining malaria transmission in the area. Thus, compromising the effectiveness of pyrethroids-based vector control measures and the National Elimination Goal. Therefore, monitoring and managing properly insecticide resistance became a key programmatic intervention to achieve the elimination goal where feasible, as aimed by Senegal. Noteworthy, this is the first report of the ace-1 mutation in natural populations of An. arabiensis from Senegal, which need to be closely monitored to preserve one of the essential insecticide classes used in IRS to control the pyrethroids-resistant populations.

Abstract
Background: Mucocele is a benign cystic pseudo-tumor that develops within the sinus cavities. The most frequent locations are frontal and frontoethmoidal. The sphenoidal forms are rare. We report a case of sphenoidal mucocele revealed by bilateral exophthalmos. Methods and results: We report the case of a 14 year old male patient, without any particular pathological history, referred by his ophthalmologist for bilateral nasal obstruction, bilateral exophthalmos and visual acuity decrease evolving since one year. The ENT examination found a large, renitrant mass, filling the entire right nasal cavity. This mass pushed the nasal septum to the left. The CT scan showed a large sphenoidal, hypodense mass evoking a mucocele. The patient underwent endonasal marsupialization by endoscopic guidance. Conclusions: Sphenoidal mucocele is a rare cause of bilateral exophthalmos. The diagnosis can be misplaced when the signs are overt extra-sinus. Hence the interest of CT in order to eliminate other differential dignostics.

Abstract
INTRODUCTION Locoregional complications of sinusitis are dominated by oculo-orbital and/or cranioencephalic manifestations that may be life-threatening or jeopardize functional prognosis. The aim of this study was to report epidemiological, diagnostic and therapeutic aspects. MATERIALS AND METHODS A retrospective study included inpatients managed for sinusitis complications in the ENT and neurosurgery departments of the Fann university hospital center in Dakar, Senegal between January 1, 2005 and December 31, 2016. RESULTS In all, 80 files were collected. Mean age was 18.5 years, with male predominance. Mean time to treatment was 18.2 days. Cranio-encephalic complications were the most frequent (54 cases; 67.5%): mainly subdural empyema (30 cases) and brain abscess (10 cases). Seventeen patients (21.25%) had oculo-orbital complications: mainly orbital cellulitis (52.9%) and preseptal cellulitis (29.4%). Nine patients (11.25%) had both cranioencephalic and oculo-orbital complications. Acute sinusitis (82.5%) was the main cause of complications. 52.5% of patients showed pansinus involvement. Medical treatment consisted in broad-spectrum antibiotic therapy combining third-generation cephalosporins, metronidazole and gentamycin in cranio-encephalic complications and clavulanic acid and metronidazole in oculo-orbital complications. Thirty-four patients (42.5%) underwent surgical sinus drainage. Neurosurgical drainage was performed in 35 cases (43.75%). Post-treatment course was marked by 6.25% mortality (5 cases) and 16.25% sequelae. CONCLUSION With 6.25% mortality and a high rate of functional sequelae, complications of sinusitis are a serious concern in our region. Improving prognosis requires earlier management and better coordination between health professionals.

Abstract
BACKGROUND Malaria surveillance requires powerful tools and strategies to achieve malaria elimination. Rapid diagnostic tests for malaria (RDTs) are easily deployed on a large scale and are helpful sources of parasite DNA. The application of sensitive molecular techniques to these RDTs is a modern tool for improving malaria case detection and drug resistance surveillance. Several studies have made it possible to extract the DNA of Plasmodium falciparum from RDTs. The knowledge of gametocyte carriage in the population is important to better assess the level of parasite transmission in elimination settings. The aim of this study was to detect P. falciparum gametocytes from used RDTs by quantitative PCR for molecular monitoring of malaria transmission. METHODS DNA was extracted from 303 RDT devices (SD Bioline Malaria Pf) using the Chelex-100 protocol. qPCR was performed in a 20 μL reaction to detect and quantify transcripts of the pfs25 gene. The cycle threshold (Ct) was determined by the emission fluorescence corresponding to the initial amount of amplified DNA. RESULTS The study found an overall prevalence of 53.47% with an average Ct of 32.12 ± 4.28 cycles. In 2018, the prevalence of gametocytes was higher in the Ranérou district (76.24%) than in the Saint-Louis district (67.33%) where an increase in the number of gametocyte carriers in 2018 was noted, in comparison with 2017. CONCLUSIONS RDTs are a good source of DNA for molecular monitoring of gametocyte carriage. This method is a simple and effective tool to better understand the level of malaria transmission with a view to elimination.

Abstract
Strokes can significantly affect the autonomy and the ability of the patient to feed properly. Malnutrition after strokes increases the length of stay in hospital, increases mortality and aggravates disability. Nutritional support is a therapeutic that can be useful in the management of strokes and during the rehabilitation period. It may help to reduce the occurrence of complications due to the physical dependence associated with this condition. The objective of our study was to evaluate, through a questionnaire, the opinion of prescribing doctors working in the Department of Neurology of The FANN National Teaching Hospital in Dakar. The interest of the question resides in the fact that the Center does not have a dedicated nutritionist for inpatients. This was an opinion poll about their concerns about the nutritional status of patients in the therapeutic projects they propose during the stroke. The type of the chosen opinion poll was elementary, type random. The questionnaire was individual and consisted of five items of single-response and multiple-choice questions. The results of this study reveal that while the nutritional status of patients with limited autonomy in the service was a concern in the intentions of the prescribers, in practice it was not taken into account in therapeutic projects. To date, no structured protocol is available in cases of proven nutritional deterioration in patients. Nutritional management must be integrated into the overall management of Neurology patients, particularly in elderly victims of strokes.

Abstract
Tuberculosis is an endemic disease in Senegal. Cutaneous forms are rare and are characterized by their clinical polymorphism. They account for 2% of the extrapulmonary locations of tuberculosis [1, 2]. We report an observation of a tuberculous gumma of the buttock that led to the discovery of an active pulmonary localization in an immunocompetent adult. A 47-year-old man was admitted for a painful swelling of the right buttock that had been developing for four years. The physical examination noted an indurated, multinodular, and polyfistulized plaque, with confluent yellowish pus emission, on the inferomedial face of the right buttock, associated with bilateral inguinal lymphadenopathy. Cutaneous tuberculosis was found in the histology, which showed TB granuloma, and the gastric tube fluid was positive for acid-fast bacilli. Thoracoabdominopelvic CT showed multiple basal acinar micronodules in both lungs. Serology was negative for both HIV and HBV. All signs of tuberculosis disappeared after six months of treatment. In endemic zones, cutaneous tuberculosis is characterized by its clinical polymorphism. It must also be looked for in any perineal abscess. Early management greatly improves the prognosis.

Abstract
Hydatidosis, an anthropozoonosis caused by the development of the Echinococcus granulosus larva in human, is a parasitic infection that is endemic in many countries. Pericardial localization in the absence of other cardiac involvement is extremely rare. Its spontaneous evolution is serious because of the risk of rupture. We report the case of a 65-year-old patient, who received limb edema that had been going on for 4 months, and in whom the physical examination noted a 3/6 tricuspid regurgitation and a right heart failure syndrome. Transthoracic echocardiography revealed an intra-pericardial mass whose contents appeared fluid with hyperechogenic area. It measured 86x61 mm and significantly compressed the straight cavities. Thoracic computed tomography showed an appearance in favor of an aged intrapericardic hydatid cyst (GHARBI V) with mass effect on the right cavities. The hydatid serology was negative. The patient did not accept the surgical cure. She had been put on albendazole and diuretic treatment. Fatal outcome was reported after two-month follow-up.

Abstract
OBJECTIVE to report the indications and the results of the upper urinary tract by endoscopic route by a double J probe in our Center. PATIENTS AND METHODS This was a retrospective mono-centric descriptive study from January 1st 2018 to June 30th 2019 including all patients that had a JJ stent as a type of upperurinary tract diversion. RESULTS seventy four patients were included. The average age of patients was 43.6 ± 17.5 years. The sex-ratio was 0.6. The obstructive renal colic was the most common operative indication in 62.1% (46) of patients. The etiologies were dominated by urolithiasis with 39.1% (29) of patients. Anesthesia was general in 67.5% (50) and locoregional in 32.5% of patients (24). The procedure was performed without fluoroscopic control (blind) in 66.2% of cases(49), therewere 89.7% case of success (44 patients). The success rate was 86.5% (64) patients and the failure rate 13.5% (10) of patients. Five (6.7%) patients had a postoperative acute pyelonephritis complication requiringremoval of the JJ stent. CONCLUSION The rise of the double J probe made possible to prepare the ureter, thus facilitating the endoscopic treatment of urinary lithiasis. The complication rate observed in our patients was low. The compliance with the rules of asepsis could reduce these complications.

Abstract
Abstract
BACKGROUND
Glioblastoma is the most common primary brain tumor. Its prognosis remains poor even with the standard treatment - the Stupp protocol.The classic Warburg effect in cancers leads to increased glycolysis which causes acidification of the tumor environment. This phenomenon may favor migration of tumor cells as already reported in pancreatic ductal adenocarcinoma. We therefore hypothesized that enhanced glycolysis in glioblastomas could favor the tumor cell migration.
MATERIAL AND METHODS
We measured glycolysis by the extracellular acidification rate (ECAR) of several human glioblastomas cell lines (LN229, LN18, T98-G, U87-MG, U373-MG, U118-MG) with the Seahorse Analyzer. To confirm these results, we also measured the intracellular cAMP rates using the Cayman’s Elisa kit and we analyzed by RT-PCR the expression of the main genes coding for enzymes involved in glycolysis in these glioblastomas cell lines. Cell migration was measured with a scratch wound healing assay during 24 hours.
RESULTS
U118-MG was the glioblastoma cell line with the highest glycolysis rate, the highest production of cAMP and showed a strong expression of glycolysis-associated genes. LN229 was the glioblastoma cell line with the less important glycolysis rate, the lower production of cAMP and showed a weaker expression of glycolysis-associated genes. According to the scratch wound healing assay, U118-MG cells showed a more important migration than LN229 cells at 24 hours.
CONCLUSION
Glycolysis may be an attractive target to prevent effectively tumor cell migration in glioblastomas. Coupling the evaluation of glycolysis with histomolecular characterization of glioblastomas, could help to identify patients to whom adjuvant therapies that inhibit glycolysis such as fenofibrate could be proposed.

Abstract
Vascular variations are common. A cervicofacial anatomical dissection carried out at the anatomy laboratory allowed us to document a rare vascular variation. The facial artery did not give rise to branches that led to the submandibular gland; an artery arising directly from the external carotid artery vascularized the submandibular gland and gave rise to the ascending palatine artery that led to the maxilla. We did not find cases in the literature where an artery emanated directly from the external carotid artery to vascularize the submandibular gland and that gave rise to an ascending palatine artery leading to the maxilla. Knowledge of the variations of the arterial vascularisation of the submandibular gland is important for submandibulectomies and transfers of the gland.

Abstract
Laryngeal tuberculosis (LT) is a rare disease. The therapy for LT is easy but the diagnosis remains a challenge for the pathologist and the laryngologist because of the absence of specific signs. The objective was to analyze the epidemiological and pathological profiles of LT cases in Dakar (Senegal) with a view to better understand this pathology. This study was a retrospective and descriptive of LT cases diagnosed in pathology laboratories in Senegal during five years (2011-2015). The LT was found in 9 cases. The mean age at diagnosis was 41.9 years (18/58) without sex predominance (sex-ratio = 0.8). Tobacco intoxication (3/9), tuberculosis contagion (1/9), HIV immunodepression (2/9), and diabetes (1/9) were the various risk factors found. Dysphonia was a constant symptom (9/9) associated with dysphagia (2/9) and cervical adenopathy (1/9). The macroscopic presentation was tumoral-like (7/9) and erythematosus and fibrinoid (2/9). The LT was of glottic seat in all the cases (9/9) with participation on top-glottic in two of the cases. The biopsy was performed in all patients. It reported tuberculous granuloma in four cases (4/9), tuberculoid granuloma in one case (1/9), and chronic lymphocytic laryngitis in four cases (4/9). CT-scan of the lungs was pathological in five patients (5/9). Evolution was favorable in all cases under "conventional tuberculosis treatment" over a period of six months. The diagnosis of LT requires a high collaboration between the laryngologist and the pathologist.

Abstract
Neuro-Behçet (NB) African studies are mainly North African, but Sub-Saharan Africa is not to be outdone. Our aim was to describe diagnostic and therapeutic features of NB in a Senegalese series collected in Dakar. This was a descriptive and retrospective study conducted at the Neurology department of Fann Teaching Hospital in Dakar, Senegal. All patients who met the NB's diagnostic criteria were included. Sixteen patients were collected, 14 males and 2 females with an average age of 40 years [18-71]. The main neurological signs were motor deficit (13 cases), headache (10 cases), and language disorders (4 cases). Extra-neurological signs were dermatological (14 cases), ocular (2 cases), and articular (2 cases) with aseptic unilateral gonarthritis. Fever was present in 9 patients. Neurological involvement was mostly isolated parenchymal (8 cases) or mixed (6 cases). The main clinical forms of NB were rhombencephalitis (8 cases) and retrobulbar optic neuritis (4 cases). Seven patients had a cerebral angio-Behçet with cerebral venous thrombosis (3 cases), ischemic stroke (2 cases), and intracerebral hematoma (2 cases). Under prednisone (16 cases) and azathioprine (3 cases), the short-term clinical outcome was mostly favorable (14 cases) with a modified Rankin scale at 2. NB is an under-diagnosed adult male disease in Sub-Saharan Africa and further studies are needed.

Abstract
Pityriasis versicolor (PV) is a superficial mycosis caused by yeast of the genus Malassezia. The most common isolated Malassezia species in PV lesions differ among M. furfur, M. globosa and M. sympodialis. We purpose to determine the distribution of Malassezia species in PV patients at the seafarers' medical service in Dakar, Senegal and to examine whether any association between identified Malassezia species and patients' profile. From May 2017 to August 2017, first a questionnaire was filled to get informative data before collection of skin scrapings taken from most scaly site using sterile scalpel blade and application of scotch® for direct examination (DE). At the laboratory, DE, culture and identification by MALDI-TOF MS were done. One hundred patients with PV - all men - were included with a mean age of 34 years. Among seafarers, 81% were sailors. Clinical prevalence of PV was highest in aged adults patients with ages of 31 to 60 years (56%). Seafarers with high level of education were less representative with only 2%. The mean duration of the PV was 26.83 months. 20% of subjects suffered lesions in more than one location. The chest was the most affected anatomical site. Furthermore, possible predisposing factors associated with PV were also detected. DE was positive in 95% but culture growth only in 46%. MALDI-TOF MS analysis of the positive cultures could be performed in 84.8% (39/46). Only M. furfur was identified in 100% (39/39). In definitive, M. furfur is the only causative agent of PV in Dakar.

Abstract
Etiological factors of childhood ischemic stroke depend on the epidemiological context. The purpose of this study was to determine the risk factors, the clinical and radiologic features, and the outcome of arterial ischemic stroke in a case series of Senegalese children. We carried out a retrospective registry-based study on arterial ischemic stroke in children hospitalized in the neurology department of Fann Teaching Hospital and Albert Royer Children's Hospital, from January 2005 to December 2015. We enrolled 116 cases with an age range from 2 months to 18 years. The mean age at stroke occurrence was 71.5 months. The most common manifestations were hemiparesis (84%), aphasia (19%), and partial motor seizures (10%). The middle cerebral artery was the most affected (81%). Risk factors were predominantly sickle cell disease (38%), embolic heart disease (9%), and anemia (3%). Twenty-eight percent of patients were lost to follow-up, 62% had neurological impairments, and 4% died. Secondary prevention was based on antithrombotic agents. Prevention must be prioritized and public health actions need to focus on sickle cell disease, rheumatismal disease, anemia, and related disorders. It will be necessary to set up policies that fight against consanguineous marriage, endemic infections, and argue for better nutrition.
