EPILEPTIC SEIZURES REVEALING STURGE WEBER'S DISEASE IN A TROPICAL ENVIRONMENT: STUDY OF EIGHT CASES.

In sub-Saharan Africa (SSA), the etiological factors of epilepsy are multiple and phacomatoses, in particular Sturge weber's disease, are rarely reported due to under-medicalization and insufficient multidisciplinary care. We carried out a retrospective study of 216 patients hospitalized for recurrent epileptic seizures between 2015 and 2022 in the neurology and pediatrics department of the University Hospital Center of Conakry, among whom eight (8) patients were identified for Sturge Weber's disease in order to reassess this pathology from a clinical and paraclinical point of view in a tropical environment. Sturge Weber's disease was retained in eight (8) on the presence of symptomatic partial epileptic seizures (age 6 months to 14 years) with frequency of status epilepticus, homonymous lateral hemiparesis linked to occipital involvement, piriform calcifications on imaging and ocular disorders. The delay in consultation and medical care revealed severe mental deterioration in our patients. This study shows a stereotyped clinical picture in a context of aggravation of signs related to a delay in multidisciplinary management. These results are important for the diagnostic, therapeutic and prognostic discussion.

GAYET WERNICKE'S ENCEPHALOPATHY AFTER COVID-19 IN ELDERLY SUBJECTS IN TROPICAL ENVIRONMENTS: STUDY OF SIX (6) OBSERVATIONS IN CONAKRY.

In sub-Saharan Africa, the COVID-19 pandemic has caused severe malnutrition in elderly populations with the appearance of vitamin deficiencies, in particular thiamine responsible for Gayet Wernicke's encephalopathy (EGW). We present a series of six (6) patients hospitalized in the Neurology Department of the CHU Ignace Deen for the management of a brain syndrome with vigilance disorders after recovery from COVID-19, including oculomotor disorders, motor incoordination on a course of severe weight loss. The six patients underwent an evaluation of malnutrition by determining the WHO body mass index, the Detsky index, the serum albumin assay, the thiamine assay and a neuroradiological assessment (MRI) and an electroencephalogram (EEG) examination although this does not seem necessary for diagnosis. Study of nutritional status: weight loss greater than 5%, patients in Desky group B and C, plasma albumin<30 g/l, lowered thiamine and MRI neuroradiological data: by the existence of hypersignals in certain regions of the neocortex, certain gray nuclei, the mammillary bodies the thalamic nuclei close to the wall of the 3rd ventricle and the regions bordering the 4th ventricle sign Gayet Wernicke's encephalopathy syndrome. This study shows a stereotyped clinical, biological, neuroradiological and evolutionary profile of Gayet Wernicke's encephalopathy in elderly subjects recovered from Covid-19 with proven malnutrition. These results are useful for the therapeutic and prognostic discussion.

The predictor of mortality outcome in adult patients with Ebola virus disease during the 2014-2015 outbreak in Guinea.

The purpose of this study was to examine the association of any demographic and clinical factors with mortality outcome among adult patients with Ebola virus disease (EVD) in Guinea. This retrospective observational study analyzed medical records of laboratory confirmed EVD adult patients during the 2014-2015 EVD outbreak in Guinea. The associations between any demographic or clinical variables and mortality outcome of EVD were assessed using univariate and multivariate logistic regression analyses. Of 2,310 EVD adult patients included for analysis, the overall case fatality rate was 68.1%. Univariate analyses identified factors possibly associated with mortality outcome, including patient age (p < 0.001), history of visiting or close contact with a suspected or confirmed EVD patient (p = 0.035), and seven clinical symptoms on admission, i.e., fever (p = 0.003), hiccups (p < 0.001), vomiting (p = 0.003), diarrhea (p < 0.001), cough (p = 0.001), sore throat (p = 0.016), and unexplained bleeding (p = 0.021). The multivariate analysis showed that patient age was independently associated with mortality outcome of EVD (OR = 1.06; 95%CI = 1.03-1.09; p < 0.001), while none the of clinical symptoms on admission were significantly associated with the mortality outcome. Our analysis indicates that older age was the only independent factor associated with death among EVD adult patients in Guinea. This suggests that older EVD patients should receive intensive medical care and be carefully monitored.

On-chip conductometric detection of short DNA sequences via electro-hydrodynamic aggregation.

Fluorescence measurement is the main technology for post-amplification DNA detection in automated systems. Direct electrical reading of DNA concentration in solution could be an interesting alternative to go toward more miniaturized or less expensive devices, in particular in the pathogen detection field. Here we present the detection of short bacterial biomarkers with a direct impedancemetric measurement, within solutions of amplified and elongated DNA sequences in a microchannel. This technology relies on the electrohydrodynamic instability occurring in solutions of long charged macromolecules in a strong electric field. This instability specifically induces the aggregation of long DNAs and triggers conductivity variations that can be monitored by on-contact conductometry. An innovative isothermal amplification and elongation strategy was developed, combining SDA and HRCA reactions, in order to yield long DNAs suitable to be detected by the above principle, from a dilute initial DNA target. In contrast with previous label-free detection methods, this new strategy is very robust to matrix effects, thanks to the unique molecular weight dependence of the instability, coupled with this specific DNA amplification strategy. We demonstrate the detection of a 1 pM gene sequence specific to Staphylococcus aureus, in a portable system.

Morphology and ultrastructure of the antennal sensilla of Sitophilus granarius (Coleoptera: Curculionidae).

Sensilla are sense organs in insects, typically consisting of a group of cuticle or epidermal cells that appear as hairs or rod-shaped structures. Sensilla serve as the functional elements of sensory systems. The goal of this study was to determine the type and distribution of sensilla in the antennae of Sitophilus granarius (L.) using light microscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). This is one of the first studies in which the morphology and distribution patterns of sensilla on antennal segments of male and female S. granarius have been investigated using SEM, followed by TEM. Different morphological sensilla types, including two sensilla basiconica (SB) types, with two subtypes, four sensilla coeloconica (SC) types and five sensilla chaetica (SCH) types, with one subtype, have been identified on S. granarius antennae, whose external structure and shape are peculiar. TEM micrographs of SB on the antennae of S. granarius are characterized by strongly corrugated pores around the cuticle, while micrographs of SC longitudinal sections showed flat-tipped and smooth-surfaced pegs bearing an apical pore that is suggestive of a gustatory function. TEM micrographs of SCH longitudinal sections showed dendrite branches and cuticular pore arrow heads that may be involved in the perception of humidity, temperature, heat and CO2. Because SCH of different sizes were distributed around the head and rostrum, these may function as contact-chemoreceptors .These results are discussed in relation to the possible roles of the sensilla types in the host location behavior of S. granarius.

[Hepatitis B: cross-sectional study of knowledge and immunization among students at University of Cocody, Ivory Coast]. / Connaissance et couverture vaccinale contre l'hépatite virale B (HVB) : étude transversale parmi les étudiants de l'université de Cocody, Côte d'Ivoire.

BACKGROUND: To evaluate knowledge about hepatitis B and vaccination coverage among students at Cocody's University, Ivory Coast. MATERIALS AND METHODS: A cross-sectional study was conducted during the academic year 2005-2006 (2557 students). Parameters were collected by interview using a survey chart. Factors influencing knowledge and vaccination against hepatitis B were analyzed by logistic regression. RESULTS: The majority of students (n=1174, 69.4% [95% CI 68-71]) knew about hepatitis B. Only 17.5% and 26.1% of students respectively were aware of sexual and blood transmission. None of the students were aware of maternal-fetal transmission. Factors associated with knowledge of hepatitis B were enrollment in health sciences (Odds Ratio=24.19 [95% CI 8.65-76.63]) and having a scholarship (Odds Ratio=2.34 [95% CI 1.54-3.56]). Vaccination coverage against hepatitis B was low (Odds Ratio=3.7% [95% CI 3-4]). Factors associated with vaccination were: knowledge of hepatitis B (Odds Ratio=6.83 [95% CI 4.57-10.27]), enrollment in health sciences (Odds Ratio=3.59 [95% CI 2.60-4.96]), marriage (Odds Ratio=2.04 [95% CI 1.13-3.64]) and having a scholarship (Odds Ratio=1.60 [95% CI 1.09-2.35]). CONCLUSION: Knowledge and vaccination coverage against hepatitis B among students at Cocody's University is low. Students should be given information about hepatitis B and access to free vaccination. Students enrolled in health sciences should be vaccinated before admission because of specific risks of contamination, for themselves and for their patients.

[Social integration of women operated for obstetric urogenital fistula]. / Intégration sociale des femmes opérées de fistule urogénitale obstétricale.

OBJECTIVE: To study the social integration of women supported in the urology department of the University Hospital of Point G for obstetric urogenital fistula. PATIENTS AND METHOD: Prospective study conducted over a period of 13 months from June 2008 to June 2009 in the Department of Urology at the University Hospital of Point G. The study included all patients who have been operated on at least twice for obstetric fistula genitourinary. Records of surgical, medical records and tracking sheets for each patient were the media database. RESULTS: Situation before treatment: before surgical treatment, 76.92% of patients were rejected by their spouses. The family attended the patient in 84.62% of cases. Situation after treatment: after treatment, 90.31% of women with fistula lived in the matrimonial home or family. The resumption of business activity was announced by 11.2% of patients. Among the women, 93.7% participated in housework. The number of patient intervention ranged from two to five. Healing (fistula closed and no sphincter dysfunction) was complete in 50% of cases. Among the women, 11.54% had sphincter dysfunction after closure of the fistula, which makes a total of fistula closed more than 61% after at least two attempts. CONCLUSION: The urogenital fistulas are not a fatal disease but is a real handicap for women who suffer to conduct a socio-cultural and economic mainstream. Generally excluded from the ongoing operations of the company, these women are more integrated after successful surgical treatment of the fistula.

[Issues inherent to the management of disorders of sex development in Point G Hospital]. / Problématique de la prise en charge des anomalies de la différenciation sexuelle dans le service d'urologie : CHU Point G.

Abnormal sexual development causes unconformity between gender identity and gender role. In countries with low socio-economic level, the optimal management is difficult. The aim of this study was to evaluate the frequency, the genital anatomy appearance, the diagnostic and the surgical management of disorders of sex development (DSD) discovered during the adolescence. Between January 2005 and November 2006 (23 months), five patients with abnormal sexual development were identified in Point G Hospital. First-line testing included biology measurement and imaging. A surgical management was systematically offered. Median age was 19.5±11.8 years (6-31). All patients were initially assigned male. Sexual dimorphic with genital ambiguity was the first reason of consultation (three children to five). One patient had male breast development and one had pelvic pain. All clinical evaluation suggested genital ambiguity. The diagnostic was female pseudohermaphrodism in three cases, true hermaphrodism in one case and hypogonadism for one patient. A masculinizing genital surgery was performed in three cases. The other patients refused the treatment or were out of sight. Intersex disorders are relatively rare in Mali with a prevalence of 2.30‰ in our hospital. This study highlighted the lack of financial means and local resources for optimal clinical management of individuals with DSD.

Ischemic strokes revealing neurosyphilis: Study of six (6) observations at the neurology Department of the University Hospital of Conakry.

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.

[Foreskin Cyst After Circumcision At The Hospital Of Sikasso (MALI)]. / Kyste Du Moignon Preputial Post Circoncision Traditionnelle A L'Hopital De Sikasso (MALI).

Cyst scar post circumcision of the stump of the prepuce is pathology of which we have not found any cases in the literature. The circumcision traditional is still practiced in our regions with its attendant complications, in particular, the high section, the whole or part of the gland, infections. The case we report concerns a patient 24 years of age, having a large cyst of 8cm diameter, evolving for the past 17 years. The patient has not informed his parents that when the desire to marry has become very pressing. The consultation was motivated by the psychological trauma, the discomfort and the pain caused by the infection, and the fistulisation. The treatment was surgical with bedroom suites. This observation underscores the importance of the knowledge of good surgical technique in order to minimize complications; it also sheds light on the taboo side of the pathologies the sphere uro-genitale.

Le kyste cicatriciel post circoncision du moignon du prépuce est une pathologie dont nous n'avons pas trouvé de cas dans la littérature. La circoncision traditionnelle est toujours pratiquée dans nos régions, avec son cortège de complications, notamment l'hémorragie, la section partielle ou totale du gland, les infections. Le kyste cicatriciel post circoncision traditionnelle que nous rapportons concerne un patient de 24 ans présentant un volumineux kyste de 08cm de diamètre, évoluant depuis 17ans. Le patient n'a informé ses parents que lorsque le désir de se marier est devenu très pressant. La consultation fut motivée par le traumatisme psychologique, la gêne et la douleur provoquée par l'infection et la fistulisation. Le traitement a été chirurgical avec des suites simples. Cette observation souligne l'importance de la maitrise de la bonne technique opératoire afin de minimiser les complications de la circoncision traditionnelle, elle met aussi la lumière sur le côté tabou des pathologies touchant la sphère uro-génitale.

Performance of Mali's biosafety level 3 laboratory in the external quality assessment in preparedness of laboratory accreditation and support to clinical trials.

Background: The external quality assessment (EQA) or external quality control is an evaluation conducted by a certified external organization to inquire about the quality of the results provided by a laboratory. The primary role of EQA is to verify the accuracy of laboratory results. This is essential in research because research data should be published in international peer-reviewed journals, and laboratory results must be repeatable. In 2007, the University Clinical Research Center (UCRC's) biosafety level 3 (BSL-3) laboratory joined the EQA program with the College of American Pathologists in acid-fast staining and culture and identification of mycobacteria as per laboratory accreditation preparedness. Thus, after 11 years of participation, the goal of our study was to evaluate the performance of our laboratory during the different interlaboratory surveys. Methods: We conducted a descriptive retrospective study to evaluate the results of UCRC mycobacteriology laboratory from surveys conducted during 2007 and 2017. Results: Of the 22 evaluations, the laboratory had satisfactory (100% of concordance results) in 18 (81.8%) and good (80% of concordance results) in 4 (18.2%). Overall, the laboratory was above the commended/accepted limits of 75%. Conclusion: So far, UCRC's BSL-3 performed well during the first 11 years of survey participation, and efforts should be deployed to maintain this high quality in the preparedness for laboratory accreditation and support to clinical trials.

Fluorescein diacetate and rapid molecular testing for the early identification of rifampicin resistance in Mali.

BACKGROUND: Non-conversion on auramine smear microscopy indicates a lack of treatment response, possibly associated with initial rifampicin-resistant tuberculosis (RR-TB). However, dead bacteria still stain positive and may be detected. Fluorescein diacetate smear microscopy (FDA) shows live mycobacteria only. Therefore, we studied the potential of 2-month (2M) FDA for the identification of initial RR-TB.METHODS: Between 2015 and 2018, we enrolled new smear-positive pulmonary TB patients from five local centres in Bamako, Mali. After baseline screening, sputum samples were collected at 1M, 2M, 5M and 18M. We used rpoB sequencing to identify initial RR-TB.RESULTS: Of 1359 patients enrolled, 1019 (75%) had rpoB sequencing results. Twenty-six (2.6%, 95%CI: 1.7-3.7) had mutations conferring rifampicin resistance. Most frequent rpoB mutations were located at the codons Asp435Val (42.4%) and Ser450Leu (34.7%). Among patients with initial RR-TB, 72.2% were FDA-negative at 2M (P = 0.2). The positive and negative predictive value of 5M FDA for culture-based failure was respectively 20.0% and 94.7%.CONCLUSION: FDA did not identify the majority of patients with initial RR-TB or culture-based failure. As the full spectrum of mutations identified on sequencing was identified using Xpert, our data support its rapid universal implementation in Mali.

Retrospective surveillance of HIV prevalence in blood donors can help in the selection of the best social group for blood donation in Mali.

The National Centre for Blood Transfusion, Bamako, Mali has collected data that characterizes trend in HIV prevalence over 10 years by gender, age, occupation, marital status and donor category. These data help to describe national HIV prevalence and assist in formulating blood donation policies. Donations from 1993 to 2002 were categorized by donor age (decade), occupation (student, military and other), marital status (single, married and other), gender and donor status (volunteer, occasional and family). Comparisons were made using conservative estimates of donation frequency/donor category. Donations increased by more than 400%. By 1999, increased HIV prevalence in donations from women was consistently present. Donations from the age group of 30-39 years showed an increased prevalence beginning in 2000, which by 2002 was almost 10 times greater than in the low-prevalence (<20 years) group (5.9 vs. 0.6%). By 2000, both categories - students and military were less likely to be HIV positive than those from other occupational categories, and donations from married persons were less likely to be HIV positive by 1997. The highest prevalence was observed in the 'occasional' donor category, which increased to >14% by 2001; volunteer donation HIV positive peaked at 2.3% in 1999. HIV prevalence in blood donations in Bamako, Mali, demonstrates important trends from 1993 to 2002. The prevalence of > 14% in donations from occasional donors and significant trends by decade, gender, marital status and occupation argue for increased analysis of the blood donor population to improve blood safety and to understand the demographics of HIV infection in Mali.

Variation in the ICAM1 gene is not associated with severe malaria phenotypes.

Evidence from autopsy and in vitro binding studies suggests that adhesion of erythrocytes infected with Plasmodium falciparum to the human host intercellular adhesion molecule (ICAM)-1 receptor is important in the pathogenesis of severe malaria. Previous association studies between polymorphisms in the ICAM1 gene and susceptibility to severe malarial phenotypes have been inconclusive and often contradictory. We performed genetic association studies with 15 single nucleotide polymorphisms (SNPs) around the ICAM1 locus. All SNPs were screened in a family study of 1071 trios from The Gambia, Malawi and Kenya. Two key non-synonymous SNPs with previously reported associations, rs5491 (K56M or 'ICAM-1(Kilifi)') and rs5498 (K469E), were tested in an additional 708 Gambian trios and a case-control study of 4058 individuals. None of the polymorphisms were associated with severe malaria phenotypes. Pooled results across our studies for ICAM-1(Kilifi) were, in severe malaria, odds ratio (OR) 1.02, 95% confidence interval (CI) 0.96-1.09, P=0.54, and cerebral malaria OR 1.07, CI 0.97-1.17, P=0.17. We assess the available epidemiological, population genetic and functional evidence that links ICAM-1(Kilifi) to severe malaria susceptibility.

Benefit of direct-acting antiviral therapy for hepatitis C virus (HCV) in monoinfected and HIV-HCV-coinfected patients with mixed cryoglobulinaemia.

OBJECTIVES: Mixed cryoglobulinaemia (MC) is found in 40-60% of patients with chronic hepatitis C virus (HCV) infection. Direct-acting antiviral (DAA) regimens considerably improve clinical outcome of HCV infection with sustained virological response rates (SVR) above 90%. We aimed to evaluate the impact of DAA therapy on cryoglobulin clearance and on MC-related symptoms in patients with HCV-associated MC. METHODS: Thirty-five HCV-monoinfected and 12 HIV-HCV-coinfected patients with symptomatic or asymptomatic MC treated with DAA regimen were analysed. Cryoglobulin levels were assessed at DAA initiation, at different time points during treatment and after treatment and until cryoglobulin clearance if any. RESULTS: Median age was 61 years and 51% (24/47) were males. HIV patients had all undetectable HIV RNA with combined antiretroviral therapy. MC was symptomatic in 77% (27/35) of HCV-monoinfected patients and in 8% (1/12) of HIV-HCV-coinfected patients (p < 0.001). Fifty-one per cent (24/47) of patients were previous non-responders to pegylated-interferon/ribavirin (PEG-IFN/RBV) therapy and 32% (15/47) were cirrhotics. One patient received DAA + PEG-IFN/RBV and all others received an IFN-free DAA regimen. The overall SVR12 rate was 100%. Cryoglobulinaemia persisted in 34% (n = 16/47) of patients at the end of follow-up: 17% (2/12) of HIV-HCV-coinfected and 40% (14/35) of HCV-monoinfected patients. Among these patients, median cryoglobulin level decreased from 101.4 mg/L at DAA treatment initiation to 51.7 mg/L at the end of follow-up. CONCLUSIONS: DAA-induced SVR allows cryoglobulin clearance in two-thirds of patients.
