Abstract
INTRODUCTION In sub-Saharan Africa (SSA), the clinical and progressive diagnostic certainty of AIDS dementia is difficult to establish due to under-medicalization and delays in consultation and especially the diversity of etiologies of demented states. MATERIAL AND METHODS We carried out a retrospective study of 196 patients hospitalized for dementia syndrome between 2016 and 2021 in the neurology department of the University Hospital of Conakry. The criteria labeled in this study are those retained by the DSM-IV and the classification of the American Academy of Neurology (AAN) developed in accordance with the WHO. RESULTS HIV etiology was identified in patients aged 44-67 years (17 women and 19 men). The clinical picture was dominated by severe cognitive disorders, slowed ideation, memory disorders and reduced motor skills associated with personality changes. Neurological examination revealed dysphoric disorders in most patients, sphincter abnormalities in 13 cases and labio-lingual tremor in 11 cases. Diagnosis was based on positive serological tests for HIV1 antibodies (25 cases) and HIV2 antibodies (1 case) using the Elisa and Western blot techniques, and the presence of discretely hypercellular CSF. Magnetic resonance imaging contributed to the diagnosis, showing diffuse white matter abnormalities with hyper signals on T2-weighted or FLAIR sequences. CONCLUSION This study shows a non-stereotype clinical picture of AIDS dementia requiring a differential diagnosis with other infectious dementias. These results are important for the therapeutic and prognostic discussion.

Abstract
Introduction In sub-Saharan Africa (SSA), stroke is a major public health problem and the etiological aspects are poorly studied and documented because of under-medicalization; the syphilitic etiology is rarely mentioned. Patients and methods We performed a retrospective study of 472 patients hospitalized for ischemic stroke between 2016 and 2021 in the Neurology Department of the University Hospital of Conakry, confirmed by neuroradiological explorations (brain CT, MRI-Angio) and a biological workup including VDRL-TPHA serological reactions in blood and CSF. Results Syphilitic etiology was retained for six (6) patients (4 men and 2 women) with a mean age of 43 years (extremes 36 and 49 years). The clinical picture was dominated by carotid syndromes: superficial and deep sylvian syndrome, anterior cerebral artery syndrome and vertebro-basilar syndromes and one case of lacunar syndrome.The diagnosis was based on the positivity of serological reactions (VDRL-TPHA) in blood and cerebrospinal fluid (CSF) and the presence of a predominantly lymphocytic hypercellularity and a hyperproteinorachy in the CSF in the absence of any other etiology. Conclusion These neurological vascular syndromes consecutive to a cerebral treponematous attack are often the result of a still poorly conducted management of primary and secondary syphilis in our country.

Abstract
Cryptogenic stroke is an old definition that designates an ischemic stroke with no identifiable cause. The term of the embolic stroke of undetermined source was then introduced to identify non-lacunar strokes in whom thromboembolism was the likely mechanism. This subgroup of cryptogenic strokes remains heterogeneous with many potential and possibly associated embolic causes. Covert atrial fibrillation is probably less often involved than initially expected, in contrast to intracranial and extracranial atherosclerosis. The cardiologist should be involved in the search of underlying causes of ischemic stroke by helping the neurologist to identify the most likely diagnosis. Further research is necessary to select populations that may benefit from more effective and individualized treatment.

Abstract
The aim of our study was to determine the frequency of extended-spectrum beta-lactamase (ESBL) phenotypes among the enterobacteria present in blood cultures of patients at admission to two university hospitals of Bamako (Mali). During a period of three months, we isolated enterobacteria from blood cultures from patients upon admission to the Point G and Gabriel Toure University Hospitals. The ESBL-positive enterobacteria were initially identified by API 20E strips and VITEK®2 and then confirmed in France by MALDI-TOF mass spectrometry at the Bichat Hospital bacteriology laboratory. Antibiotic susceptibility was determined by the diffusion method as recommended by EUCAST. The species isolated were K. pneumoniae (14/40, 35.0 %), E. coli (11/40, 27.5 %), and E. cloacae (9/40, 22.5 %); 21/34 (61.8 %) had an ESBL phenotype, including 10/14 (71.4 %) K. pneumoniae, 8/11 (72.7 %) E. coli, and 3/9 (33 3 %), E. cloacae. The ESBL strains of K. pneumoniae, E. coli, and E. cloacae were associated, respectively, with resistance to the following antibiotics: gentamicin (10/10, 100 %; 6/8, 75%; 2/3, 67%), amikacin (2/10, 20 %; 0/8, 0%; 0/3, 0%), ofloxacin (8/10, 80. %; 7/8, 87%; 3/3, 100%), cotrimoxazole (10/10, 100 %; 6/8, 75%; 3/3, 100%). Almost two thirds (61.8%) of the enterobacteria isolated from blood cultures produced extended-spectrum beta-lactamases. They retained regular sensitivity only to carbapenems and amikacin.

Abstract
The worldwide dissemination of extended-spectrum beta-lactamase producing Enterobacteriaceae, (ESBL-E) and their subset producing carbapenemases (CPE), is alarming. Limited data on the prevalence of such strains in infections from patients from Sub-Saharan Africa are currently available. We determined, here, the prevalence of ESBL-E/CPE in bacteriemic patients in two teaching hospitals from Bamako (Mali), which are at the top of the health care pyramid in the country. During one year, all Enterobacteriaceae isolated from bloodstream infections (E-BSI), were collected from patients hospitalized at the Point G University Teaching Hospital and the pediatric units of Gabriel Touré University Teaching Hospital. Antibiotic susceptibility testing, enzyme characterization and strain relatedness were determined. A total of 77 patients had an E-BSI and as many as 48 (62.3%) were infected with an ESBL-E. ESBL-E BSI were associated with a previous hospitalization (OR 3.97 95% IC [1.32; 13.21]) and were more frequent in hospital-acquired episodes (OR 3.66 95% IC [1.07; 13.38]). Among the 82 isolated Enterobacteriaceae, 58.5% were ESBL-E (20/31 Escherichia coli, 20/26 Klebsiella pneumoniae and 8/15 Enterobacter cloacae). The remaining (5 Salmonella Enteritidis, 3 Morganella morganii 1 Proteus mirabilis and 1 Leclercia adecarboxylata) were ESBL negative. CTX-M-1 group enzymes were highly prevalent (89.6%) among ESBLs; the remaining ones being SHV. One E. coli produced an OXA-181 carbapenemase, which is the first CPE described in Mali. The analysis of ESBL-E relatedness suggested a high rate of cross transmission between patients. In conclusion, even if CPE are still rare for the moment, the high rate of ESBL-BSI and frequent cross transmission probably impose a high medical and economic burden to Malian hospitals.

Abstract
INTRODUCTION The increasing frequency of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae is becoming a serious public health concern. This study sought to determine ESBL frequency in Enterobacteriaceae isolated from patients' blood cultures in two university teaching hospitals of Bamako, Mali. METHODOLOGY During a three-month period, the presence of Enterobacteriaceae from blood cultures of patients admitted to the university teaching hospitals of Bamako was evaluated. The microbial identifications were initially performed with an API 20E gallery and VITEK2 locally in Mali, and then confirmation in France was performed with a mass spectrometry MALDI-TOF in the bacteriology laboratory of the university teaching hospital of Bichat. Antibiotic susceptibility profiles were determined by the diffusion method as recommended by the European Committee on Antimicrobial Susceptibility Testing (EUCAST). RESULTS The isolated species were K. pneumoniae (14/40; 35.0%), E. coli (11/40; 27.5%), and E. cloacae (9/40; 22.5%). Of the strains isolated, 21/34 (61.8%) had an ESBL phenotype, including 10/14 (71.4%) K. pneumoniae, 8/11 (72.7%) E. coli, and 3/9 (33.3%) E. cloacae. Resistances associated with ESBL strains of K. pneumoniae, E. coli, and E. cloacae were as follows: gentamicin (10/10, 100%; 6/8, 75%; 2/3, 67%, respectively), amikacin (2/10, 20%; 0/8, 0%; 0/3, 0%, respectively), ofloxacin (8/10, 80%; 7/8, 87%; 3/3, 100%, respectively), and cotrimoxazole (10/10, 100%; 6/8, 75%; 3/3, 100%, respectively). CONCLUSION Almost two-thirds (61.8%) of Enterobacteriaceae isolated from our blood cultures were ESBL producers. Only susceptibilities to carbapenems and to amikacin were fully conserved within the strains.

Abstract
Extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae have been isolated from many regions of the world. Epidemiological studies are being conducted in Europe, North America, and Asia. No study has however been conducted in Africa to determine the prevalence and distribution of ESBLs on the continent. This literature review aimed at describing the prevalence of ESBL-producing Enterobacteriaceae isolated from blood cultures, as well as the ESBL genes involved at the international level. Our focus was mainly on Africa. We conducted a literature review on PubMed. Articles related to our study field and published between 1996 and 2014 were reviewed and entirely read for most of them, while we only focused on the abstracts of some other articles. Relevant articles to our study were then carefully reviewed and included in the review. The prevalence of ESBL-producing Enterobacteriaceae differs from one country to another. The results of our literature review however indicate that class A ESBLs prevail over the other types. We took into consideration articles focusing on various types of samples to assess the prevalence of ESBL-producing Enterobacteriaceae, but information on isolates from blood cultures is limited. The worldwide prevalence of ESBL-producing Enterobacteriaceae has increased over time. Evidence of ESBL-producing Enterobacteriaceae can be found in all regions of the world. Studies conducted in Africa mainly focused on the Northern and Eastern parts of the continent, while only rare studies were carried out in the rest of the continent.

Abstract
Cardiovascular and neurological manifestations associated with thiamine deficiency in Guinean prisons are common but not reported.We performed a prospective study of 38 cases related to vitamin B1 deficiency over a period of 4 years. In this population, the literature of traditional data gathered: frequency peak after thirty (92.6%) and clear representation male (sex ratio M/F: 18/1). The clinical symptomatology remains essentially dominated by sensorimotor polyneuropathy and pure sensory (52.2%), overall heart failure (31.5%) and to a lesser degree by Gayet Wernicke's encephalopathy (7.8%) and shoshin beriberi with severe evolution (5.2%). The study of nutritional status by body mass index (BMI) of the World Health Organization, by the criteria of Detsky and biological markers including albumin, shows that these patients are severely malnourished.

Abstract
Neurological disorders related to vitamin B12 deficiency are common in prisons of tropical Africa. We collected 22 cases (20 men and 2 women). They all showed vitamin B12 deficiency associated with neurological signs that were represented by sclerosis combined with bone marrow (n = 9), peripheral neuropathy (n = 6), cerebellar syndrome (n = 2), a pyramidal syndrome of the lower limbs (n = 4) and optic neuropathy (n = 1). Laboratory tests showed a mean hemoglobin concentration of 7.2 ± 1.5 g/dl, mean 104 ± 28 fl, macrocytic anemia in 10 patients. Biermer's disease was identified in 9 patients, 3 patients showed the syndrome of non dissociation of vitamin B12, a gastrectomy in 2 patients and no etiology was identified in 8 patients.

Abstract
Sex determination mechanisms are thought to evolve rapidly and show little conservation among different animal species. For example, the critical gene on the Y chromosome, SRY, that determines sex in most mammals, is not found in other animals. However, a related Sox domain transcription factor, SOX9, is also required for testis development in mammals and exhibits male-specific gonad expression in other vertebrate species. Previously, we found that the Drosophila orthologue of SOX9, Sox100B, is expressed male-specifically during gonad development. We now investigate the function of Sox100B and find, strikingly, that Sox100B is essential for testis development in Drosophila. In Sox100B mutants, the adult testis is severely reduced and fails to interact with other parts of the reproductive tract, which are themselves unaffected. While a testis initially forms in Sox100B mutants, it fails to undergo proper morphogenesis during pupal stages, likely due to defects in the pigment cells. In contrast, no substantive defects are observed in ovary development in Sox100B mutant females. Thus, as is observed in mammals, a Sox9 homolog is essential for sex-specific gonad development in Drosophila, suggesting that the molecular mechanisms regulating sexually dimorphic gonad development may be more conserved than previously suspected.

Abstract
The authors report 13 cases of Gayet-Wernicke's encephalopathy observed in 13 patients of a refugee population. 11 presented the classical triad: oculomotor signs, cerebral ataxia and state of confusion and in 2 patients, only 2 symptoms were noted. The etiological factors: chronic alcoholism, malnutrition, uncontrollable vomiting, HIV and tuberculosis were identified. The outcome was evaluated on the basis of the disappearance of symptoms after treatment with 500 mg of thiamine in 7 patients, 1 death and 5 patients progressed toward Korsakoff amnesic syndrome.
