Abstract
BACKGROUND Artemether-lumefantrine is widely used for uncomplicated Plasmodium falciparum malaria; sulfadoxine-pyrimethamine plus amodiaquine is used for seasonal malaria chemoprevention. We aimed to determine the efficacy of artemether-lumefantrine with and without primaquine and sulfadoxine-pyrimethamine plus amodiaquine with and without tafenoquine for reducing gametocyte carriage and transmission to mosquitoes. METHODS In this phase 2, single-blind, randomised clinical trial conducted in Ouelessebougou, Mali, asymptomatic individuals aged 10-50 years with P falciparum gametocytaemia were recruited from the community and randomly assigned (1:1:1:1) to receive either artemether-lumefantrine, artemether-lumefantrine with a single dose of 0·25 mg/kg primaquine, sulfadoxine-pyrimethamine plus amodiaquine, or sulfadoxine-pyrimethamine plus amodiaquine with a single dose of 1·66 mg/kg tafenoquine. All trial staff other than the pharmacist were masked to group allocation. Participants were not masked to group allocation. Randomisation was done with a computer-generated randomisation list and concealed with sealed, opaque envelopes. The primary outcome was the median within-person percent change in mosquito infection rate in infectious individuals from baseline to day 2 (artemether-lumefantrine groups) or day 7 (sulfadoxine-pyrimethamine plus amodiaquine groups) after treatment, assessed by direct membrane feeding assay. All participants who received any trial drug were included in the safety analysis. This study is registered with ClinicalTrials.gov, NCT05081089. FINDINGS Between Oct 13 and Dec 16, 2021, 1290 individuals were screened and 80 were enrolled and randomly assigned to one of the four treatment groups (20 per group). The median age of participants was 13 (IQR 11-20); 37 (46%) of 80 participants were female and 43 (54%) were male. In individuals who were infectious before treatment, the median percentage reduction in mosquito infection rate 2 days after treatment was 100·0% (IQR 100·0-100·0; n=19; p=0·0011) with artemether-lumefantrine and 100·0% (100·0-100·0; n=19; p=0·0001) with artemether-lumefantrine with primaquine. Only two individuals who were infectious at baseline infected mosquitoes on day 2 after artemether-lumefantrine and none at day 5. By contrast, the median percentage reduction in mosquito infection rate 7 days after treatment was 63·6% (IQR 0·0-100·0; n=20; p=0·013) with sulfadoxine-pyrimethamine plus amodiaquine and 100% (100·0-100·0; n=19; p<0·0001) with sulfadoxine-pyrimethamine plus amodiaquine with tafenoquine. No grade 3-4 or serious adverse events occurred. INTERPRETATION These data support the effectiveness of artemether-lumefantrine alone for preventing nearly all mosquito infections. By contrast, there was considerable post-treatment transmission after sulfadoxine-pyrimethamine plus amodiaquine; therefore, the addition of a transmission-blocking drug might be beneficial in maximising its community impact.

Abstract
Information on population structure and connectivity of targeted species is key for proper implementation of spatial conservation measures. We used a combination of genomics, biophysical modelling, and biotelemetry to infer the population structure and connectivity of Atlantic meagre, an important fisheries resource throughout its distribution. Genetic samples from previously identified Atlantic spawning locations (Gironde, Tejo, Guadalquivir, Banc d'Arguin) and two additional regions (Algarve and Senegal) were analysed using genome-wide SNP-genotyping and mitochondrial DNA analyses. Biophysical models were conducted to investigate larval dispersal and connectivity from the known Atlantic spawning locations. Additionally, thirteen fish were double-tagged with biotelemetry transmitters off the Algarve (Portugal) to assess movement patterns and connectivity of adult individuals. This multidisciplinary approach provided a robust overview of meagre population structure and connectivity in the Atlantic. Nuclear SNP-genotyping showed a clear differentiation between the European and African populations, with significant isolation of the few known Atlantic spawning sites. The limited level of connectivity between these subpopulations is potentially driven by adults, capable of wide-ranging movements and connecting sites 500 km apart, as evidenced by tagging studies, whilst larval dispersal inferred by modelling is much more limited (average of 52 km; 95% of connectivity events up to 174 km). Our results show sufficient evidence of population structure, particularly between Africa and Europe but also within Europe, for the meagre to be managed as separate stocks. Additionally, considering the low degree of larvae connectivity, the implementation of marine protected areas in key spawning sites could be crucial towards species sustainability.

Abstract
Sequence analysis of Plasmodium falciparum parasites is informative in ensuring sustained success of malaria control programmes. Whole-genome sequencing technologies provide insights into the epidemiology and genome-wide variation of P. falciparum populations and can characterise geographical as well as temporal changes. This is particularly important to monitor the emergence and spread of drug resistant P. falciparum parasites which is threatening malaria control programmes world-wide. Here, we provide a detailed characterisation of genome-wide genetic variation and drug resistance profiles in asymptomatic individuals in South-Western Mali, where malaria transmission is intense and seasonal, and case numbers have recently increased. Samples collected from Ouélessébougou, Mali (2019-2020; n = 87) were sequenced and placed in the context of older Malian (2007-2017; n = 876) and African-wide (n = 711) P. falciparum isolates. Our analysis revealed high multiclonality and low relatedness between isolates, in addition to increased frequencies of molecular markers for sulfadoxine-pyrimethamine and lumefantrine resistance, compared to older Malian isolates. Furthermore, 21 genes under selective pressure were identified, including a transmission-blocking vaccine candidate (pfCelTOS) and an erythrocyte invasion locus (pfdblmsp2). Overall, our work provides the most recent assessment of P. falciparum genetic diversity in Mali, a country with the second highest burden of malaria in West Africa, thereby informing malaria control activities.

Abstract
BACKGROUND In some settings, sensitive field diagnostic tools may be needed to achieve elimination of falciparum malaria. To this end, rapid diagnostic tests (RDTs) based on the detection of the Plasmodium falciparum protein HRP-2 are being developed with increasingly lower limits of detection. However, it is currently unclear how parasite stages that are unaffected by standard drug treatments may contribute to HRP-2 detectability and potentially confound RDT results even after clearance of blood stage infection. This study assessed the detectability of HRP-2 in periods of post-treatment residual gametocytaemia. METHODS A cohort of 100 P. falciparum infected, gametocyte positive individuals were treated with or without the gametocytocidal drug primaquine (PQ), alongside standard artemisinin-based combination therapy (ACT), in the context of a randomised clinical trial in Ouelessebougou, Mali. A quantitative ELISA was used to measure levels of HRP-2, and compared time to test negativity using a standard and ultra-sensitive RDT (uRDT) between residual gametocyte positive and negative groups. RESULTS Time to test negativity was longest by uRDT, followed by ELISA and then standard RDT. No significant difference in time to negativity was found between the treatment groups with and without residual gametocytes: uRDT (HR 0.79 [95% CI 0.52-1.21], p = 0.28), RDT (HR 0.77 [95% CI 0.51-1.15], p = 0.20) or ELISA (HR 0.88 [95% CI 0.59-1.32], p = 0.53). Similarly, no difference was observed when adjusting for baseline asexual parasite density. Quantified levels of HRP-2 over time were similar between groups, with differences attributable to asexual parasite densities. Furthermore, no difference in levels of HRP-2 was found between individuals who were or were not infectious to mosquitoes (OR 1.19 [95% CI 0.98-1.46], p = 0.077). CONCLUSIONS Surviving sexual stage parasites after standard ACT treatment do not contribute to the persistence of HRP-2 antigenaemia, and appear to have little impact on RDT results.

Abstract
Pathological conditions of the falciform ligament are rare, one of which is the twisting of a fatty fringe that can lead to fatty infarction of the peritoneal fat. To our knowledge, only 21 cases with radiological documentation have been published in the literature. Ultrasound and computed tomography facilitated prompt diagnosis of this rare finding. The condition is best managed conservatively, but sometimes, a surgical intervention is necessary. We report herein a case of torsion of fatty falciform ligament appendage in a 73-year old female.

We aimed to establish the efficacy and safety of three single low doses of tafenoquine in combination with dihydroartemisinin-piperaquine for reducing gametocyte density and transmission to mosquitoes. METHODS In this four-arm, single-blind, phase 2, randomised controlled trial, participants were recruited at the Clinical Research Unit of the Malaria Research and Training Centre of the University of Bamako in Mali. Eligible participants were aged 12-50 years, with asymptomatic P falciparum microscopy-detected gametocyte carriage, had a bodyweight of 80 kg or less, and had no clinical signs of malaria defined by fever. Participants were randomly assigned (1:1:1:1) to standard treatment with dihydroartemisinin-piperaquine, or dihydroartemisinin-piperaquine plus a single dose of tafenoquine (in solution) at a final dosage of 0·42 mg/kg, 0·83 mg/kg, or 1·66 mg/kg. Randomisation was done with a computer-generated randomisation list and concealed with sealed, opaque envelopes. Dihydroartemisinin-piperaquine was administered as oral tablets over 3 days (day 0, 1, and 2), as per manufacturer instructions. A single dose of tafenoquine was administered as oral solution on day 0 in parallel with the first dose of dihydroartemisinin-piperaquine. Tafenoquine dosing was based on bodyweight to standardise efficacy and risk variance. The primary endpoint, assessed in the per-protocol population, was median percentage change in mosquito infection rate 7 days after treatment compared with baseline. Safety endpoints included frequency and incidence of adverse events. The final follow-up visit was on Dec 23, 2021; the trial is registered with ClinicalTrials.gov, NCT04609098. FINDINGS From Oct 29 to Nov 25, 2020, 1091 individuals were screened for eligibility, 80 of whom were enrolled and randomly assigned (20 per treatment group). Before treatment, 53 (66%) individuals were infectious to mosquitoes, infecting median 12·50% of mosquitoes (IQR 3·64-35·00). Within-group reduction in mosquito infection rate on day 7 was 79·95% (IQR 57·15-100; p=0·0005 for difference from baseline) following dihydroartemisinin-piperaquine only, 100% (98·36-100; p=0·0005) following dihydroartemisinin-piperaquine plus tafenoquine 0·42 mg/kg, 100% (100-100; p=0·0001) following dihydroartemisinin-piperaquine plus tafenoquine 0·83 mg/kg, and 100% (100-100; p=0·0001) following dihydroartemisinin-piperaquine plus tafenoquine 1·66 mg/kg. 55 (69%) of 80 participants had a total of 94 adverse events over the course of the trial; 86 (92%) adverse events were categorised as mild, seven (7%) as moderate, and one (1%) as severe. The most common treatment-related adverse event was mild or moderate headache, which occurred in 15 (19%) participants (dihydroartemisinin-piperaquine n=2; dihydroartemisinin-piperaquine plus tafenoquine 0·42 mg/kg n=6; dihydroartemisinin-piperaquine plus tafenoquine 0·83 mg/kg n=3; and dihydroartemisinin-piperaquine plus tafenoquine 1·66 mg/kg n=4). No serious adverse events occurred. No significant differences in the incidence of all adverse events (p=0·73) or treatment-related adverse events (p=0·62) were observed between treatment groups. INTERPRETATION Tafenoquine was well tolerated at all doses and accelerated P falciparum gametocyte clearance. All tafenoquine doses showed improved transmission reduction at day 7 compared with dihydroartemisinin-piperaquine alone. These data support the case for further research on tafenoquine as a transmission-blocking supplement to standard antimalarials. FUNDING Bill & Melinda Gates Foundation.

Abstract
INTRODUCTION Dislocations of the knee are serious, involving the functional prognosis and sometimes the vital prognosis of the limb concerned. The aim of our work was to assess the functional results of our care. MATERIALS AND METHODS This were a prospective study concerning patients with dislocation of the knee, treated and followed in the Department of Orthopedics-Traumatology at the CHU Gabriel TOURE from January 2015 to October 2018. RESULTS We collected 30 patients with knee dislocation. The male sex predominated (60%) with a sex ratio of 1.5. The average age was 32.56 years. AVP was the main etiology with 83.3%. The mechanism was direct in 86.7%. Standard knee X-ray with front and side views was performed in all patients. Posterolateral dislocation was the most common type of pathology (20%). Associated lesions were observed in 56.6%. The response time was less than 6 hours in 100%. The treatment was orthopedic in 93.3%. Complications were dominated by knee laxity with 43%. At the average follow-up of 18.9 months, the functional results were good in 20%. CONCLUSION Knee dislocations are the prerogative of the young subject. Accidents due to motorcycles are the main circumstances. Associated lesions are frequent. Orthopedic treatment is still relevant but the evolution is still unpredictable despite the early treatment.

Abstract
INTRODUCTION Acetabularfractures involving the functionalprognosis of the hip. The aim of thisworkwas to determine the epidemiological, clinical, and outcome aspects of treatment. MATERIALS AND METHODS This wasa retro-prospective study of patients withacetabulum fracture treated and followedfromJanuary 2015 to June 2018. RESULTS Wecollected 49 patients with an acetabulum fracture. Acetabulum fractures made up 8.3% of all pelvic injuries during the studyperiod. The male sexprevailed (87.8%) with a sex ratio of 7.16. The averageagewas 36.14 years (range: 17 years and 77 years). The circumstances of the trauma were accidents on the public highway (69.4%), accidents atwork (14.3%), accidents in the home (10.2%), accidents in sports (4.1%), assaults (2%). The mechanismwas indirect in 87.8%.Pain with total functional impotence wasobservedin 83.7% and with a vicious attitude of the traumatized limbin 89, 8%. The standard radiographywith the incidences of the pelvis face as well as the ¾ wing and ¾ obturatorwasperformed in all patients. The transverse fracture of the acetabulumwas the mostcommonanatomo-radiological type (61.2%). Shock (34.6%) and hip dislocation (24.4%) were the mostcommonearly complications. Treatment was orthopedicin 95.9%. After an averagefollow-up of 23.24 months, the anatomicalresultsweresatisfactoryin 32.7% and the functionalresults good in 51%. Lameness (91.8%), mechanical pain (30.6%) and osteoarthritis (16.3%) were the main complications in the medium term. CONCLUSION Fractures of the acetabulum are the preserve of the adult, especially of the male. The complications are dominated by mechanical pain, lameness and early hip osteoarthritis. The anatomicalresultsthat condition the functionalresults are less good with the orthopedictreatment.

Abstract
Mosquitoes (Diptera, Culicidae) form a family of insects of considerable public health importance. Mention of their presence/absence was tackled in the literature and by specialized websites for eight African countries: Cape Verde, Mauritania, Senegal, Gambia, Mali, Burkina Faso, Niger and Chad. In total, 216 species have been recorded belonging to 13 genera: Anopheles (48 species), Aedeomyia (2), Aedes (62), Coquillettidia (6), Culex (54), Culiseta (1), Eretmapodites (7), Ficalbia (3), Lutzia (1), Mansonia (2), Mimomyia (7), Toxorhynchites (4) and Uranotaenia (19). The presence of these species in the study area is certain except for three species whose presence is doubtful. This specific richness represents 6% of the world's richness. The countries with the highest specific richness are Burkina Faso (162 species), Senegal (143) and Mali (110); the country with the lowest richness is Cape Verde (11). This richness is lower in the north in hyper-arid climate and higher in the south in sub-humid climate. Chad is the least well inventoried country. All species are considered native, with the exception of Ae. (Stegomyia ) albopictus (the Asian tiger mosquito) introduced in 2016 into Mali and possibly Ae. (Ochlerotatus ) caspius into Mauritania and Ae. (Stg. ) aegypti introduced into Nouakchott, Mauritania. This synthesis of the knowledge may be useful for vector control, public health, and future research.

Abstract
Objective The purpose of this study was to analyse the socio-anthropological determinants (representations, beliefs, practices and perceptions of health services) of the high prevalence of obstetric fistulas in Guinea. Patients and methods From January 15 to February 15, 2018, we carried out a qualitative study in three health centres (one urban and two rural). The study focused on biological mothers who attended the centres to get vaccinated their children. The data were collected by semi-structured individual interview. Results None of the 42 respondents could link the occurrence of obstetric fistulas and obstructed labour. Participants at all three study sites believed that obstructed labour and obstetric fistula have a mystical origin. In Kissidougou, the respondents thought that obstructed labour and obstetric fistulas are caused either by soubaya, sorcery in Malinké or the evil spell korte in Malinké cast by an enemy, or the bad behaviour of the parturient which means either she practices adultery or if she behaves disrespectfully towards elders. In Dubréka, the respondents linked the occurrence of labour dystocia and obstetric fistula to witchcraft koromikhi in Sousou. In Labé, some respondents thought that obstructed labour and obstetric fistula are due to divine punishment in local dialect lette Allah when the woman does not respect her husband or has contracted the pregnancy out of the legal union. Others deemed that childbirth is difficult because of the narrowness of the delivery route in Fulani lawol ngol no faadhi in parturients who do not have sex during pregnancy or when the woman had not adequately had female circumcision, in local dialect o suuwaaki laabhi which means, part of the clitoris was left in place during the excision. The majority of respondents had a poor perception of health services (male staff, lack of privacy, poor hygiene, abuse). Several cultural practices (early wedlocks, genital mutilations, dietary restrictions, home deliveries) also induce obstetric fistulas. Conclusion Respondents' cultural beliefs and practices regarding childbirth limit women's attendance at maternity hospitals during childbirth and favour obstetric fistulas.

Abstract
INTRODUCTION The rapid diagnostic capacities of laboratories in Mali have been an essential element in the response to COVID-19. The University Clinical Research center (UCRC) diagnosed the first cases of Mali COVID-19. OBJECTIVE The objective was to describe the contribution of the UCRC in the diagnosis of Covid-19 and to clinically and epidemiologically characterize the patients tested in the UCRC laboratory. MATERIALS AND METHODS A cross-sectional study was conducted during eight months of intense activity. The samples were sent from the National Institute of Public Health (INSP) to the UCRC. RESULTS The UCRC tested 12,406 contacts and suspected samples and confirmed the diagnosis in 1091 patients, or 9%. The most common symptoms were cough (48.78%), headache (34.14%), fatigue / weakness (34.14%), while (33.33%) of the patients were asymptomatic. The sample positivity rate among new cases decreased from May to September 2020, despite almost 230% of the number of samples tested. CONCLUSION The laboratory played a major role in the response and there may be a low transmission of the virus in the Malian community.

Abstract
BACKGROUND Healthcare-associated infections are the most frequent adverse events in healthcare worldwide, with limited available evidence suggesting highest burden in resource-limited settings. Recent Ebola epidemics emphasize the disastrous impact that spread of infectious agents within healthcare facilities can have, accentuating the need for improvement of infection control practices. Hand hygiene (HH) measures are considered to be the most effective tool to prevent healthcare-associated infections. However, HH knowledge and compliance are low, especially in vulnerable settings such as Guinea. The aim of PASQUALE (Partnership to Improve Patient Safety and Quality of Care) was to assess knowledge and compliance with HH and improve HH by incorporating the WHO HH Strategy within the Faranah Regional Hospital (FRH), Guinea. METHODS In a participatory approach, a team of FRH staff and leadership was invited to identify priorities of the hospital prior to the start of PASQUALE. The local hygiene committee was empowered to increase its activities and take ownership of the HH improvement strategy. A baseline assessment of knowledge, perception and compliance was performed months before the intervention. The main intervention consisted of local alcohol-based-hand-rub (ABHR) production, with final product efficacy testing, in conjunction with a training adapted to the needs identified in the baseline assessment. A follow-up assessment was conducted directly after the training. Effectiveness of the intervention was assessed via uncontrolled before-and-after comparison. RESULTS Baseline knowledge score (13.0/25) showed a significant increase to 19.0/25 in follow-up. Baseline-Compliance was 23.7% and increased significantly to 71.5% in follow-up. Compliance rose significantly across all professional groups except for midwifes and in all indications for HH, with the largest in the indication "Before aseptic tasks". The increase in compliance was associated with the intervention and remained significant after adjusting for confounders. The local pharmacy successfully supplies the entire hospital. The local supply resulted in a ten-fold increase of monthly hospital disinfectant consumption. CONCLUSION The WHO HH strategy is an adaptable and effective method to improve HH knowledge and compliance in a resource-limited setting. Local production is a feasible method for providing self-sufficient supply of ABHR to regional hospitals like the FRH. Participatory approaches like hygiene committee ownership builds confidence of sustainability.

Abstract
"Blast hand" is a traumatic hand injury related to an explosion. Artisanal gold miners use dynamite to excavate gold pits; such activities expose them to blast hand injuries. This work aims to study blast injuries to gold miners' hands. A 25-month retrospective study was performed. Data on the traumatic event, patients, and injuries were collected and analyzed. Dedicated classifications and scores were used to evaluate the injury topography, injury severity, physical dependence, and aesthetic impact. Data were analyzed statistically. Thirty patients with 46 blast hand injuries among 516 hand injuries were collected. All patients were males and full-time artisanal gold miners. They were seen in the emergency room an average of 10.2hours (1-72) after the explosion. Explosions were caused by a 500g dynamite charge in all cases. The detonation was mainly thermal (n=13), triggered by the patient himself (n=24) and inside the gold pit (n=20). Injuries were bilateral (53%) or left side predominant (59%). Complex injuries were present in 21 hands. The MHISS (Modified Hand Injury Severity Score) was severe (n=7) and major (n=32). Associated injuries were musculoskeletal (n=12), ophthalmologic (n=14) and maxillofacial (n=10). Complexes injuries were correlated to being inside the pit at the time of the explosion. Treatment was conservative more often (n=33) than amputation (n=13). The functional recovery was complete in 22 hands (10 patients). Return to work at the same level was possible for only eight hands (5 patients). The presence of local sequelae or associated injuries negatively impacted the return to work. In Burkina Faso, gold miner's blast hand injuries cause post-traumatic social and professional reintegration issues. Better regulation of artisanal gold mining and expansion of treatment modalities (microsurgery, hand rehabilitation, splinting) may improve the outcome.

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
INTRODUCTION The objective of this study was to determine the incidence of the operating site infection, precise the etiologies and identify the risk factors. PATIENTS AND METHOD This was a prospective study conducted at the department of orthopedics and traumatology at the hospital of Sikasso. The study was conducted from January 2016 to December 2018. The infection criteria were those of CDC from Atlanta. RESULT This study was conducted on 140 patients including 105 men and 35 women with an average age of 40, 1 years old (3 and 88 years old). We have made 150 interventions including 131 osteosynthesis, 14 arthroplasties and 5 corrective osteotomies. The global incidence of the operating site infection was of 19, 3% with a 13, 4% incidence in surgery class I, 21, 4% in the class II, 26, 5% in the class III and 50% in the class IV. . It was superficial in 18 cases (62, 1%) and deep in 11 cases (37, 9%). The average post-surgery hospitalization duration was 13 days (5 and 70 days in extreme cases). The isolated germs were Staphylococcus aureus in 6 cases (37,5 %), Pseudomonas aeruginosa in 3 cases (18,7 %), Enterobacter cloacae in 3 cases (18,7%), Escherichia Coli in 2 cases (12,5 %,), Klebsiellapneumoniae in 1 case (6,3%) and Proteus mirabilis in 1 case (6,3%). They were 100% sensible to imipramine. 90% of the cases were resisting to ampicillin and penicillin G. CONCLUSION The incidence of the ISO in our department was high. The risk factors of Operating Sites Infections were: hospitalization duration beyond 2 days, ASA Score over 2 days long, the surgical intervention class and the operation duration higher than 3 hours.

Abstract
AIM To determine the frequency of the surgery wound infection, its favoring factors, causative germs and its antibiotic treatment of choice in the surgery "A" department of the University Hospital Point G. METHOD In a retrospective descriptive study over a 6-month period in the surgery "A" department of the University Hospital Point G, we enrolled all patients who underwent surgery necessitating at least 48 hours of hospital admission during our study period and in conformity with the Atlanta CDC criteria. Surgery patients with less than 48 hours postoperative hospital stay and those admitted to the hospital without surgery were not included.After the surgery, the nature and location of the infection have been clarified. In this work, ethical considerations have been respected and there is no conflict of interest. RESULTS Two hundred and sixty-five (n=265) patient files were collected including 24 cases of surgery wound infection (a hospital frequency of 9%. The average age was 41.41 years (y.o) old with extremes of 7 y.o and 102 y.o. The sex ratio was 0.9 in favor of women. The commonly studied pathologies were digestive surgery in 52.8%, gynecological surgery in 24.5%, etc… Patients were seen in regular outpatient surgery visits in 75.8% and surgical emergencies in 24.2%. Of the patients urgently admitted, 26.5% presented an ISO; for those received in ordinary consultation it was 3.48%. Fifteen (15) cases were classified ASA III and two (2) ASA II. Based on the Altemeier classification, surgery was clean in 66.8% of our patients, contaminated clean in 12.4%, contaminated in 12.1%, and dirty in 8.7% (including half resulting in surgery wound infection). In total, 79% of patients whose surgeries lasted more than two (2) hours presented a surgery wound infection. Postoperative infection of patients was superficial in 58.3% and deep in 33.3%. In 8.3% of cases, it was a space infection. At the cytobacteriological examination of the pus from the operative site, Escherichia coli (E. coli) was the most common germ with 58.3%. E. coli was sensitive to amoxicillin-clavulanic acid in 57.14%. Surgically, a re-intervention was performed in 20.8% of cases, a secondary suture in 12.5%, and a single dressing in 66.7%. The average postoperative stay was 6.5 days with extremes of 2 days and 69 days. In 3 months postoperatively we recorded 4 cases of death. CONCLUSION The surgery wound infection constitutes a major complication in a surgical environment starting with surgical act itself.Particular emphasis should be placed on prevention, which will reduce the risks of ISO occurrence.

Abstract
Envenomation by snakebite can lead to hematological, circulatory, digestive, renal, and neurological complications. Brain abscess after snakebite envenomation is exceptional and very rarely reported in the literature. In this article, we describe the clinical case of a 45-year-old woman with no particular history, admitted to our department for vigilance disturbances linked to a motor deficit on the right side and fever after viper bite on the left thumb. The clinical examination showed a marked biological inflammatory syndrome. The brain scan with iodine injection suggested a left fronto-parietal brain abscess. Tri-antibiotic therapy, combined with the administration of corticosteroids, resulted in favorable outcome.

Abstract
The GloPID-R (Global Research Collaboration for Infectious Disease Preparedness) chikungunya (CHIKV), o'nyong-nyong (ONNV) and Mayaro virus (MAYV) Working Group has been established to investigate natural history, epidemiology and clinical aspects of infection by these viruses. Here, we present a report dedicated to entomological aspects of CHIKV, ONNV and MAYV. Recent global expansion of chikungunya virus has been possible because CHIKV established a transmission cycle in urban settings using anthropophilic vectors such as Aedes albopictus and Aedes aegypti. MAYV and ONNV have a more limited geographic distribution, being confined to Africa (ONNV) and central-southern America (MAYV). ONNV is probably maintained through an enzootic cycle that has not been characterized yet, with Anopheles species as main vectors and humans as amplification hosts during epidemics. MAYV is transmitted by Haemagogus species in an enzootic cycle using non-human primates as the main amplification and maintenance hosts, and humans becoming sporadically infected when venturing in or nearby forest habitats. Here, we focused on the transmission cycle and natural vectors that sustain circulation of these viruses in their respective locations. The knowledge of the natural ecology of transmission and the capacity of different vectors to transmit these viruses is crucial to understand CHIKV emergence, and to assess the risk that MAYV and ONNV will expand on wide scale using anthropophilic mosquito species not normally considered primary vectors. Finally, the experts identified knowledge gaps and provided adapted recommendations, in order to address future entomological investigations in the right direction.

Abstract
The GloPID-R (Global Research Collaboration for Infectious Disease Preparedness) chikungunya (CHIKV), o'nyong-nyong (ONNV) and Mayaro virus (MAYV) Working Group has been established to identify gaps of knowledge about the natural history, epidemiology and medical management of infection by these viruses, and to provide adapted recommendations for future investigations. Here, we present a report dedicated to ONNV epidemiological distribution. Two large-scale ONNV outbreaks have been identified in Africa in the last 60 years, interspersed with sporadic serosurveys and case reports of returning travelers. The assessment of the real scale of ONNV circulation in Africa remains a difficult task and surveillance studies are necessary to fill this gap. The identification of ONNV etiology is made complicated by the absence of multiplex tools in co-circulation areas and that of reference standards, as well as the high cross-reactivity with related pathogens observed in serological tests, in particular with CHIKV. This is a specific obstacle for seroprevalence studies, that necessitate an improvement of serological tools to provide robust results. The scarcity of existent genetic data currently limits molecular epidemiology studies. ONNV epidemiology would also benefit from reinforced entomological and environmental surveillance. Finally, the natural history of the disease deserves to be further investigated, with a specific attention paid to long-term complications. Considering our incomplete knowledge on ONNV distribution, GloPID-R CHIKV, ONNV and MAYV experts recommend that a major effort should be done to fill existing gaps.

Abstract
Thymic epithelial tumors (TET) are rare lesions. The brain metastases of these tumors are even rarer. We report a case of brain metastases in a known patient with a thymic carcinoma diagnosed in October 2016. She was a 73-year-old woman who presented with headache, nausea, and right hemiplegia. Brain MRI revealed five lesions (1 insular, 1 frontal and 2 left temporal, 1 right parafalcine). These lesions were initially treated using two stereotactic radiosurgery gamma knives. A macroscopically complete excision of the left frontal lesion was subsequently performed without any complications with a good evolution of the neurological symptoms postoperatively. Immunohistochemical examination was compatible with metastatic thymic carcinoma. The patient died 14 months after the initial diagnosis. A review of the literature in English has reported another 45 TET cases with brain metastases.

Abstract
We report here a case of intraventricular schwannoma. This location is rare. Our patient was a 68-year-old female with a large intraventricular lesion of the body of the lateral ventricle on the right side. Brain magnetic resonance imaging (MRI) revealed this lesion. After a right parietotemporal craniotomy, microsurgical excision using neuronavigation was performed to completely remove the tumor. Histological and immunohistochemical examination confirmed the diagnosis of intraventricular schwannoma devoid of atypical features. Postoperative MRI showed macroscopically complete tumor removal with no recurrence after 12 months of follow-up. A review of the literature identified 32 such cases published to date.

Abstract
BACKGROUND Newborn screening for sickle cell anemia is necessary in Africa where the disease is more frequent. Hemoglobin electrophoresis is used for screening, but is limited by a high cost and difficult access. Sickling test (Emmel test), which is more affordable and technically more accessible, is often requested for prenatal assessment of pregnant women in West African areas to reserve screening for newborns from mothers in whom the positive sickling test attests the presence of hemoglobin S. This study aims to evaluate the number of undetected sickle cell anemia newborns by a screening policy targeting only newborns from mothers in whom a sickling test would have been positive. METHODS From 2010 to 2012, in Bamako, Mali, West Africa, 2489 newborns were routinely screened for sickle cell anemia at the umbilical cord or heel by isoelectrofocusing and, if necessary, by high-performance liquid chromatography. These newborns were born from 2420 mothers whose hemoglobin was studied by isoelectrofocusing. The data was recorded and processed using Excel software version 14.0.0. We calculated the frequency of the sickle cell gene in mothers and newborns as well as the number of SCA newborns from heterozygous or C homozygous mothers. RESULTS Of the 2489 newborns, 16 had sickle cell anemia (6 SS and 10 SC); 198 had the sickle cell trait; 139 were AC and 1 was CC. Of the 10 newborns with SC profile, 3 were born from mothers not carrying the S gene but the C gene of hemoglobin and in which an Emmel test would have been negative. CONCLUSION Targeted newborn screening, based on the results of sickling test in pregnant women, would misdiagnose more than one of six sickle cell anemia newborns who would not benefit from early care. Cost-effectiveness studies of routine newborn screening for sickle cell anemia should lead to a better screening strategy in contexts where hemoglobin S and other hemoglobin defect genes coexist.

Abstract
AIM Our aim was to evaluate the diagnosis and therapeutic aspects of the amoebic liver abscesses in the surgery «A» department of the University hospital Point "G". PATIENTS AND METHODS Were included in this study, patients admitted to the surgery «A» department for amoebic liver abscess confirmed by a positive amoebic serology and the chocolate appearance of bacteria-free pus. Bacterial liver abscesses were not included into this study. RESULTS Over a 10-year period, 52 cases of patients diagnosed with amoebic liver abscess were collected in the department. There were 41 men and 11 women, with a sex ratio of 3.7. The mean age was 37.8 years old with extremes of 15 and 66 years. The most represented professions were farmers (36.5%) followed by salesmen (26.7%) and students (11.5%). The average outpatient visit delay time was 18.5 days with the extremes of 5 and 34 days. The most frequent clinical signs were pain in the right hypochondrium (86.5%), fever (78.8%) and hepatomegaly (61.5%). Abdominal ultrasound showed a single located abscess in 44 patients (84.6%) and these abscesses were localized in the right hepatic lobe in 34 patients(65.4%). The average volume of the abscess was 366.5 cm3 with the extremes of 36 cm3 and 1580 cm3. Amoebic serology was positive in 38 patients (80.9%). Cytobacteriological analysis of pus in 37 patients (71%) was negative. Patients underwent an ultrasound assisted needle aspiration of pus in 65.4% he. Laparotomy and a laparoscopic approach were performed in 7.7% and in 5.8%, respectively. The clinical course was uneventfulin 94.2%. The mean hospital stay duration was 16.5 days with the extremes of 4 and 29 days. No death was recorded during hospitalization. CONCLUSION Amoebic liver abscess is an uncommon pathology in a surgical setting. Abdominal ultrasound andechography guided liver puncture allowed the diagnosis. Laparoscopic approach minimizes the burden of the laparotomy.

Abstract
The production of acetone, butanol and ethanol by fermentation of renewable biomass has potential to become a valuable industrial process. Mechanisms of solvent production and sporulation involve some common regulators in some ABE-producing clostridia, although details of the links between the pathways are not clear. In this study, we compare a wild-type (WT) Clostridium beijerinckii NRRL B-598 with its mutant strain OESpo0A, in which the gene encoding Spo0A, an important regulator of both sporulation and solventogenesis, is overexpressed in terms of solvent and acid production. We also compare morphologies during growth on two different media: TYA broth, where the WT culture sporulates, and RCM, where the WT culture does not. In addition, RT-qPCR-based analysis of expression profiles of spo0A, spoIIE, sigG, spoVD, ald and buk1 genes involved in sporulation or solvent production in these strains, were compared. The OESpo0A mutant did not produce spores and butanol titre was lower compared to the WT, but increased amounts of butyric acid and ethanol were produced. The gene spo0A had high levels of expression in the WT under non-sporulating culture conditions while other selected genes for sporulation factors were downregulated significantly. Similar observations were obtained for OESpo0A where spo0A overexpression and downregulation of other sporulation genes were demonstrated. Higher expression of spo0A led to higher expression of buk1 and ald, which could confirm the role of spo0A in activation of the solventogenic pathway, although solvent production was not affected significantly in the WT and was weakened in the OESpo0A mutant.

Abstract
UNLABELLED We present a middle-aged man with features of diabetes insipidus, visual and mental impairments as a result of metastases from bronchogenic carcinoma. This case is being presented because it is uncommon; high index of suspicion and the relevant imaging techniques are required for diagnosis. Surgical resection of the pituitary secondaries with post-operative chemo-radiation brought resolution of symptoms. CONCLUSION In conclusion, hypothalamic metastases are uncommon and are often associated with compression of the pituitary gland and optic chiasma leading to diabetes insipidus, visual impairment and mental defects. MRI for diagnosis and surgical resection followed with chemoradiation lead to improvement of symptoms but mortality is high.

Abstract
Hernia is described as the protrusion of an organ into the wall of its normal containing cavity. Internal hernia (IH) involves protrusion of viscera through: a peritoneal or mesentery defect, a normal or abnormal compartment of the peritoneal cavity. Hernias occurring in the pelvis cavity are usually classified according to the fascial margins breached and include sciatic, obturator and those through the rectouterin pouch: elytrocele and enterocele. Those hernias are defined by the protrusion of a viscus through the wall of the pelvis due to weakness of the pelvic fascia and/or muscles. Pelvic hernia through the pouch of Douglas (PD) involves the genital tract in female (elytrocele and enterocele). Sometimes described in the literature as Douglas hernia, this type of hernia must be distinguished from the conventional IH. As defined before, the borders to be considered for IH is the peritoneal membrane, which is not a real solid wall but delimitates the peritoneal cavity; and there is no peritoneal defect in elytrocele or enterocele. A PubMed search for IH through a defect in the peritoneal PD revealed only five female cases, making this an extremely rare condition. To our knowledge, we have presented here the only published case in a male. This probably congenital and morphologic anomaly (defect) of pouch of Sir Douglas must be distinguished as the real "Douglas IH". Authors discuss the concept of a new and more detailed classification of IH.

Abstract
Lupus vulgaris is a common presentation of cutaneous tuberculosis (TB), but its ulcerative or vegetating form also called vorax is rare.We report a case of lupus vulgaris in its vorax form, which occurred in a patient with discoid lupus erythematous. A 42-year-old patient monitored for chronic lupus erythematosus consulted again for a facial tumor and fever. Physical examination revealed painful ulcerative and crusted lesions on an old discoid lupus lesion and covered the entire upper lip. Similar lesions were noted on cheeks. Moreover, there were cervical lymphadenopathy, a bilateral pulmonary condensation syndrome, and dysphonia. Cutaneous histopathology had revealed a tuberculoid granuloma without caseating, and nucleic acid amplification tests (GeneXpert®) performed on sputum were positive. Thus, the diagnosis of multifocal TB with skin involvement of vorax type was confirmed. The outcome was favorable following TB treatment. Our observation is distinctive as it is a granulomatosis and ulcerative form of lupus vulgaris, which occurred on a discoid lupus erythematous lesion. This is a rare form of lupus vulgaris. This scarcity can be explained by diagnostic difficulties as there are numerous differential diagnoses and histopathology is not often helpful.

Abstract
INTRODUCTION The aim of this study was to determine the sociodemographic, therapeutic, pathological and clinical aspects of patients with maxillary ameloblastoma at the University Hospital of Odonto-Stomatology (CHU OS) of Bamako. MATERIALS AND METHOD We performed a retrospective and prospective study over three years (January 2007 - December 2010), examining cases of maxillary ameloblastoma, as confirmed by clinical, associated with radiology or anatomic pathology. Data was collected from medical records, then entered and analyzed using Epiinfo. RESULTS Tumor lesions were found in 55 men and 43 women with a sex ratio of 1.27. Housewives represented the majority of cases with 35.7%. Maxillary radiography was performed on 96% of patients and biopsy in 66.3% of cases. The most common anatomical location was mandibular in 89.80% of cases, with the preferred area being the mandibular symphysis in 34.7% of cases. Conservative surgery was performed in 50% of patients and radical surgery in 26.5% of cases. CONCLUSION This study has shown a high frequency of maxillary ameloblastoma, and the fundamental benefits of early treatment, in order to minimize recidivism.
