Entomological drivers of uneven malaria transmission in urban lowland areas in Bouaké, Côte d'Ivoire.

BACKGROUND: The use of urban lowlands for agriculture contributes to the food security of city- dwellers, but promotes malaria transmission. The objective of the study was to characterize the entomological drivers of malaria transmission in two lowlands (N'Gattakro and Odiennekourani) in the city of Bouaké, Côte d'Ivoire. METHODS: The human landing catch technique was used to capture mosquitoes in houses located at the edge of two lowlands in Bouaké from February to December 2019. Cultivated surfaces were calculated monthly in both lowlands for each crop type (rice and market gardening) using images acquired by a drone. The different mosquito species were identified morphologically and by PCR analysis for the Anopheles gambiae complex. Anopheles infection by Plasmodium parasites was assessed by quantitative PCR. Mosquito diversity, biting behaviour and rhythmicity, and malaria transmission were determined in each lowland and compared. RESULTS: Anopheles gambiae sensu lato (s.l.) was predominant in N'Gattakro and Culex quinquefasciatus in Odiennekourani. Four Anopheles species were identified: An. gambiae s.l. and Anopheles funestus s.l. in both lowlands, Anopheles pharoensis in N'Gattakro, and Anopheles ziemanni in Odiennekourani. Within the An. gambiae complex, three species were caught: An. gambiae sensu stricto (s.s.), Anopheles coluzzii, and Anopheles arabiensis for the first time in Côte d'Ivoire (30.1%, 69.9% and 0% in N'Gattakro, and 45.1%, 52.6% and 2.4% in Odiennekourani, respectively). Anopheles gambiae s.l. species exhibited a significant exophagic behaviour in N'Gattakro (77.1% of outdoor bites versus 52.2% in Odiennekourani). In N'Gattakro, 12.6% of captures occurred before bedtime (09.00 pm) and after waking up (05.00 am), 15.1% in Odiennekourani. The mean human biting rate was higher in N'Gattakro than in Odiennekourani (61.6 versus 15.5 bites per person per night). Overall, Anopheles infection rate was 0.68%, with 0.539 and 0.029 infected bites per person per night in N'Gattakro and Odiennekourani, respectively. CONCLUSION: The risk of malaria in urban agricultural lowland areas is uneven. The role of agricultural developments and irrigation patterns in the production of larval habitat should be explored. The exophagic behaviour of Anopheles vectors raises the question of the residual transmission that needs to be assessed to implement appropriate control strategies.

First detection of the malaria vector Anopheles arabiensis in Côte d'Ivoire: urbanization in question.

BACKGROUND: Previous studies have revealed high malaria transmission in Bouaké, Côte d'Ivoire. The sociopolitical crisis in the country and the resulting environmental changes have raised the need to update existing knowledge on mosquito vector species and malaria transmission. METHODS: Adult mosquitoes were caught using the human landing catch (HLC) sampling method in Bouaké. They were collected in six districts representative of the diversity in urban landscapes. Sampling points were selected along the water network crossing the city and monitored from 2020 to 2021 to detect the presence of anopheline larvae. PCR techniques were used to ascertain the species of the Anopheles gambiae complex, Plasmodium falciparum sporozoite infection in a subset of Anopheles vectors, and insecticide resistance mechanisms in Anopheles arabiensis only. RESULTS: A total of 4599 Anopheles mosquitoes were collected and then identified. Anopheles gambiae sensu lato (s.l.) made up the majority of the whole collection (99%) while Anopheles funestus (0.7%), Anopheles ziemanni (0.2%), Anopheles pharoensis (0.2%) represented the remaining proportion of collection. Among the Anopheles gambiae complex, three species were identified namely An. gambiae sensu stricto (45.9%), Anopheles coluzzii (52.2%), and Anopheles arabiensis (1.9%). The first two species had already been collected in Bouaké, however this is the first time that An. arabiensis is reported in Côte d'Ivoire. Anopheles arabiensis was also collected during the larval surveys in a similar proportion (1.1%) in the same areas as the adults. CONCLUSIONS: This study detected the presence of An. arabiensis for the first time in Côte d'Ivoire. This species was found quite far from its usual geographic area and its expansion could be linked to the urbanization process. Although no An. arabiensis was found to be infected by Plasmodium sp., its role in malaria transmission in Bouaké has to be explored, particularly since its exophagic behaviour raises the issue of control measures and the use of insecticide-impregnated nets. The spread of this species in Côte d'Ivoire should be assessed through further research in additional towns in the country.

[Practices and Factors Associated with Recent HIV Testing in the General Population, Côte d'Ivoire: Results of the ANRS Study 12323 DOD-CI]. / Pratiques et facteurs associés au dépistage récent du VIH en population générale, Côte d'Ivoire. Résultats de l'étude ANRS 12323 DOD-CI.

With 2.9% of HIV prevalence in the general population, Côte d'Ivoire is one of the countries most affected by the HIV epidemic in West Africa. In this country, only 63% of people infected with HIV are aware of their status. A cross-sectional phone survey was conducted with a representative sample of 3,867 individuals to describe the practices and factors associated with a recent HIV testing (≤ 1 year) in Côte d'Ivoire. Data relative to the last done HIV test as well as the socio-demographic characteristics, sexual behavior, access to information, perceptions, capacities and autonomy as well as social and geographical environment of the participants were collected. Logistical regression models were used to identify the associated factors with a recent HIV test (≤ 1 year). Lack of information is one of the main barriers to HIV testing (only 60% of individuals know a place to get tested). For men, despite the fact that HIV testing is free of charge, poor economic conditions seem to be a barrier to testing. The social environment, including peer influence, also appears to have an effect on testing among men. For women, testing is associated with their perceptions of HIV exposure. There is a need to rethink the current HIV testing communication in Côte d'Ivoire and to identify economic or social incentives to remove access barriers to HIV testing.

Avec 2,9 % de sa population infectée par le VIH, la Côte d'Ivoire fait partie des pays d'Afrique de l'Ouest les plus touchés par l'épidémie à VIH. On estime que seules 63 % des personnes infectées par le VIH connaissent leur statut. Une enquête transversale, par téléphone, a été réalisée auprès d'un échantillon représentatif de 3 867 personnes afin de décrire les pratiques et les facteurs associés à la réalisation récente (≤ 1 an) d'un dépistage du VIH en Côte d'Ivoire. Les données collectées concernaient le dernier test réalisé ainsi que les caractéristiques sociodémographiques, comportements sexuels, accès à l'information, perceptions, capacités, autonomies ainsi que l'environnement social et géographique des participants. Des modèles de régression logistique ont été réalisés afin d'identifier les facteurs associés à la réalisation récente d'un test du VIH (≤ 1 an). Le manque d'information est l'un des principaux freins au dépistage (seuls 60 % des individus connaissent un lieu où réaliser un test). Chez les hommes, malgré la gratuité du dépistage, une faible condition économique semble être un frein à la réalisation d'un test. L'environnement social, notamment l'influence des pairs, semble aussi avoir un effet sur le recours au dépistage chez les hommes. Chez les femmes, le dépistage est associé à leurs perceptions d'exposition au VIH. L'offre de dépistage actuelle en Côte d'Ivoire nécessite de repenser la communication autour du test ainsi que d'identifier des incitatifs économiques ou sociaux permettant de lever les freins au dépistage.

Exploring the heterogeneity of human exposure to malaria vectors in an urban setting, Bouaké, Côte d'Ivoire, using an immuno-epidemiological biomarker.

BACKGROUND: In some African cities, urban malaria is a threat to the health and welfare of city dwellers. To improve the control of the disease, it is critical to identify neighbourhoods where the risk of malaria transmission is the highest. This study aims to evaluate the heterogeneity of malaria transmission risk in one city (Bouaké) in a West African country (Côte d'Ivoire) that presents several levels of urbanization. METHODS: Two cross-sectional studies were conducted in three neighbourhoods (Dar-es-Salam, Kennedy and N'gattakro) in Bouaké during both the rainy and dry seasons. Data on insecticide-treated net (ITN) use and blood samples were collected from children aged between 6 months and 15 years to determine the parasite density and the prevalence of Plasmodium falciparum and the level of IgG against the Anopheles gSG6-P1 salivary peptide, used as the biomarker of Anopheles bite exposure. RESULTS: The specific IgG levels to the gSG6-P1 salivary peptide in the rainy season were significantly higher compared to the dry season in all neighbourhoods studied (all p < 0.001). Interestingly, these specific IgG levels did not differ between neighbourhoods during the rainy season, whereas significant differences in IgG level were observed in the dry season (p = 0.034). ITN use could be a major factor of variation in the specific IgG level. Nevertheless, no difference in specific IgG levels to the gSG6-P1 salivary peptide was observed between children who declared "always" versus "never" sleeping under an ITN in each neighbourhood. In addition, the prevalence of P. falciparum in the whole population and immune responders was significantly different between neighbourhoods in each season (p < 0.0001). CONCLUSION: This study highlights the high risk of malaria exposure in African urban settings and the high heterogeneity of child exposure to the Anopheles vector between neighbourhoods in the same city. The Anopheles gSG6-P1 salivary peptide could be a suitable biomarker to accurately and quantitatively assess the risk of malaria transmission in urban areas.

[Retinal detachment surgery: Evaluation of the anatomical success and functional outcomes in a consecutive series of patients operated between 2011 and 2014 at Nantes University Medical Center]. / Chirurgie des décollements de rétine : évaluation du succès anatomique et du devenir fonctionnel sur une série consécutive de patients opérés entre 2011 et 2014 au CHU de Nantes.

OBJECTIVE: Evaluate the anatomical and functional outcomes of retinal detachment (RD) surgery from January 2011 to November 2014. MATERIALS AND METHODS: We conducted a retrospective study of 182 eyes of 175 patients with a minimum follow-up of 6 months, operated for RD at Nantes University Medical Center. It consists of 56 simple RDs and 126 complex RDs treated in first intention by Scleral Buckling (SB), vitrectomy or combined surgery. The analysis is based on anatomic reattachment at the end of a follow-up of at least 6 months after the first surgery and the progression of the best corrected visual acuity (BCVA). RESULTS: One hundred and seventy-two vitrectomies, 15 SB and 5 combined surgeries (vitrectomy+SB) were performed. The overall anatomical success rate after a single operation was 131 eyes (72 %). It increased to 163 eyes (90 %) at the end of the follow-up. Depending on the type of RD, anatomic success at 6 months after surgery was achieved for 47 simple RDs (84 %) and 84 complex RDs (67 %). At the end of the follow-up, after one or more operations, these rates increased to 53 simple RDs (95 %) and 110 complex RDs (87 %). For all RDs with an anatomically successful result, we observed a visual improvement≥2 lines in 45 % of cases and a postoperative BCVA≥5/10 in 40 % of cases. CONCLUSION: This study confirms the evolution toward vitrectomy surgery for retinal detachment. It finds anatomical and functional results consistent with the literature, with a percentage of approximately 5 % of RDs still not reattached in spite of several operations.

Lésions ostéo-articulaires traumatiques négligées des membres

Introduction - Dans les pays en voie de développement les traumatismes négligés sont fréquents. L'objectif de cette étude était de décrire les lésions ostéo-articulaires négligées des membres et leur traitement. Patients et méthodes - Il s'agissait d'une étude rétrospective descriptive. Elle a concerné 97 patients totalisant 97 lésions ostéo-articulaires négligées recensées entre 2012 et 2017. Il y avait 68 (70%) hommes et 29 (30%) femmes. L'âge moyen était de 37 ans. Les principales causes des lésions négligées étaient le traitement traditionnel initial (n=48 ;49%) et la sortie contre avis médical (n=24 ;25%). Nous avons étudié le type de lésions, leur siège, le traitement, et l'évolution. Résultats - Les cals vicieux (n=32 ;33%) et les pseudarthroses (n=22;23%) étaient les lésions les plus fréquentes. Les sièges de prédilection étaient le fémur et le tibia. Les traitements les plus réalisés étaient l'ostéotomie-ostéosynthèse (n=32 ; 33%), l'ostéosynthèse (n=27 ;28%), et la réduction sanglante des luxations (n=12 ;13%). L'évolution a été favorable chez 80 patients (82%). Conclusion - Cette étude a montré que les lésions ostéo-articulaires traumatiques négligées des membres sont dues au traitement traditionnel. Elles sont dominées par les cals vicieux et les pseudarthroses des os longs. Le traitement a été réalisé à foyer ouvert. Il a consisté en une ostéotomie avec une ostéosynthèse

[Amputation of a limb secondary to snakebite in a child]. / Amputation de membre secondaire à une morsure de vipère.

Amputation of a limb is a serious consequence of snakebite poisoning. It is caused by the toxicity of the venom and often the use of a tourniquet in some patients, which can lead to limb ischemia. Management of the victim aims to ensure survival and preserve the function of the bitten limb. Antivenom immunotherapy is the only specific treatment for ophidian envenomation. It is indicated in cases of general symptoms and signs related to the bite, but also if local damage could lead to the loss of limb function. The authors report on a case of snakebite that led to amputation at the thigh.

[Clinical, paraclinic and evolutive profile of HIV infected subject compared with that of non-HIV infected subject in pneumology hospitalization at Abidjan]. / Profil clinique, paraclinique et évolutif du sujet infecté par le VIH comparé à celui du sujet non infecté par le VIH en milieu pneumologique hospitalier à Abidjan.

INTRODUCTION: The HIV infection is a problem of public health in Côte d'Ivoire. Voluntary screening is encouraged for the premature management of HIV infected patients before the stage of serious opportunist affections. Antiretroviral therapy became free. The purpose of this study was to describe the characteristics of HIV infected subject infected in hospitalization of pneumology. METHODOLOGY: Our retrospective and analytic study concerned the activity period from January 2001 to December 2012 of pneumology department of Cocody university hospital. RESULTS: On 1141 recorded files, the prevalence of HIV infection was 48.20%. The multi-varied analysis showed the following results. Male patients were less HIV infected (OR=0.490 [0.363-0.661]) as the old patients of more than 64 years (OR=0.150 [0.080-0.280]). In case of HIV infection, infectious pathology, severe anemia and renal insufficiency were dominating respectively with OR=1.763 (1.212-2.564), OR=3.167 (2.125-4.720) and OR=2.054 (1.335-3.161). A stronger mortality was associated with HIV infection (OR=1.920 [1.312-2.809]). CONCLUSION: HIV infection always remains frequented in pneumology hospitalization in Abidjan with late discovery, source of complications and abnormally high death rate.

[Comparative diagnosis of bacterial pneumonia and pulmonary tuberculosis in HIV positive patients]. / Diagnostic comparé des pneumopathies bactériennes et de la tuberculose pulmonaire chez les patients VIH.

INTRODUCTION: Immunodepression induced by the human immunodeficiency virus (HIV) modifies the clinical, radiological and microbiological manifestations of pulmonary tuberculosis; leading to similarities between pulmonary tuberculosis and acute community-acquired bacterial pneumonia. A consequence is the high proportion of discordant pre- and post-mortem diagnoses of pneumonia. The aim of our study was to contribute to the improvement in the diagnosis of acute bacterial pneumonia in HIV positive patients in areas where tuberculosis is endemic. METHODS: This retrospective study in HIV positive patients has compared 94 cases of positive smear cases pulmonary tuberculosis and 78 cases of acute community-acquired bacterial pneumonia. RESULTS: Using logistic regression, the following features were positively associated with bacterial pneumonia: the sudden onset of signs (OR=8.48 [CI 95% 2.50-28.74]), a delay in the evolution of symptoms of less than 15 days (OR=3.70 [CI 95% 1.11-12.35]), chest pain (OR=2.81 [CI 95% 1.10-7.18]), radiological alveolar shadowing (OR=12.98 [CI 95% 4.66-36.12) and high leukocytosis (OR=3.52 [CI 95% 1.19-10.44]). These five variables allowed us to establish a diagnostic score for bacterial pneumonia ranging from 0 to 5. The area under the ROC curve was 0.886 [CI 95% 0.84-0.94, P<0.001]). Its specificity was >96.8% for a score of greater than or equal to 4. CONCLUSION: The diagnostic score for acute community-acquired pneumonia may improve the management of bacterial pneumonia in areas where tuberculosis is endemic.

Prevalence of Newcastle disease virus and infectious bronchitis virus in avian influenza negative birds from live bird markets and backyard and commercial farms in Ivory-Coast.

Newcastle disease (ND) and infectious bronchitis (IB) are two major viral diseases affecting the respiratory tracts of birds and whose impact on African poultry is still poorly known. In the present study we aimed at assessing NDV and IBV prevalences in Ivory-Coast by molecular screening of >22,000 avian swabs by nested PCR and by serology testing of close to 2000 avian sera from 2010 through 2012. The NDV and IBV seroprevalences over the study period reached 22% and 72%, respectively. We found 14.7% pooled swabs positive by PCR for NDV and 14.6% for IBV. Both pathogens are therefore endemic in Ivory-Coast. Economic losses associated with NDV and IBV infections still need to be evaluated.

[Hearing disorders at the candidates of the National Gendarmerie's competition, Ivory Coast].

Objective: Detect the hearing deficiencies of the candi­da­tes of the gendarmerie's competition. Material and method: Pros­pec­tive study realized over 3 years (2008-2010), in the ENT service of the Gendarmerie to Agban (Abidjan). Examination included an otoscopy and a pure tone audiometry. Results: On 23121 candidates, 1245 had a plug of earwax (5.4%). They were aged from 18 to 25 years old (average age: 22.85 years). Eardrum was pathological in 0.5 % of the cases. Prevalence of hearing loss was 1.5%. Hearing loss included sensorineural hearing loss (56.7%), deafness of transmission (29.4%) and mixed deafness (13.9%). Deafness was unilateral in 79.8% and bilateral in 20.2%. Conclusion: Result of audio­gram will be useful for tracking or assessing cases of noise-induced hearing loss attributable to military service.

[Interest of multidetector CT virtual hysterosalpingography in the diagnosis of utero-peritoneal fistulas about 4 cases]. / Intérêt de l'hystéroscanner dans le diagnostic de la fistule utéro-péritonéale à propos de 4 cas.

We report four cases of uterine fistula found with the multidetector CT virtual hysterosalpingography. Patients were received for suspicious of a utero-peritoneal fistula at hysterosalpingography. They were young people at childbearing age (average age of 33 years), multigravidae, two of whom were nulliparous, one primiparous and one multiparous. We noted a history of voluntary interruption of pregnancy by curettage and a cesarean section. For the opacification, we used the classic hysterography standard equipment by means of 1/5 diluted iodine with saline solution as contrast. The multidetector CT virtual hysterosalpingography revealed small uterine perforations including three which were located in uterine posterior face at cervico-isthmic area and corporeal area, bringing about a utero-peritoneal fistula. The multidetector CT virtual hysterosalpingography is a simple and powerful technique for the diagnosis of utero-peritoneal fistula. It is convenient and then deserves an important place in the evaluation of uterine fistula.

[Clinical-epidemiological profile of severe cutaneous drug reactions in children in Abidjan (Côte d'Ivoire)]. / Profil épidémio-clinique des toxidermies bulleuses chez l'enfant à Abidjan (Côte d'Ivoire).

Severe cutaneous drug reactions such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life threatening in adults. They seem to be less common in children. The purpose of this study was to describe the epidemiological, clinical and etiological profile of these drug reactions in African child. It was about a retrospective study carried on for 10 years at the Dermatology center of University Hospital of Treichville, Abidjan (Cote d'Ivoire).Were included all children aged 0-15 years hospitalized for severe cutaneous drug reaction. They represented 14.1% (27 cases) with an estimated hospital rate of 0.01%. The sex ratio (M/F) was 1.2. The mean age was 10.3 years. 19 children were suffering from SJS (63%) and 9 children (33.3%) from TEN. Sulfonamides were the most commonly used drugs with sulfadoxin-pyrimethamin (25.9%), used for malariae, and cotrimoxazole (22.2%). Self-medication was practiced by 70.4% of parents. The average time to onset of lesions from drug intake was 8.2 days. Only one child was HIV infected. Three children affected by TEN (11.1%) died.

[Stevens-Johnson syndrome and toxic epidermal necrolysis: retrospective study of 185 cases in Abidjan (Côte d'Ivoire)]. / Syndromes de Stevens-Johnson et de Lyell : étude de 185 cas au CHU de Treichville (Abidjan, Côte d'Ivoire).

BACKGROUND: Cutaneous bullous adverse drug eruptions are a dreaded complication of drug use. OBJECTIVE: The purpose of this study was to document the epidemiological features, outcomes, and causes of these reactions, in particular, Stevens-Johnson syndrome and toxic epidermal necrolysis (Lyell disease), in a teaching hospital in Abidjan (Côte d'Ivoire). PATIENTS AND METHODS: A retrospective study reviewed the records of severe cutaneous drug reactions in patients managed in the dermatology department of the University Hospital of Treichville (Abidjan) over a period of ten years (from September 2000 through August 2010). RESULTS: These diseases were diagnosed in 185 patients during the study period. Their mean age was 31.8 years (range: 2-70 years) and the M/F sex ratio was 0.6 The most frequent reactions, as expected, were Stevens-Johnson syndrome (73%) and toxic epidermal necrolysis (27%). The drugs most commonly involved were the antibacterial sulfonamides (22.1%), followed by the antiviral nevirapine (11.1%), and the antimalarial agent, sulfadoxine/pyrimethamine. The fatality rate was 22.5%, including 46% of the patients with toxic epidermal necrolysis and 14.6% of those with Stevens-Johnson syndrome. Respiratory distress (39.5%) and dehydration (23.4%) were the primary direct causes of death. CONCLUSION: Antibacterial sulfonamides are the leading drugs implicated in the occurrence of bullous drug eruptions in Abidjan.

Bayesian QTL analyses using pedigreed families of an outcrossing species, with application to fruit firmness in apple.

KEY MESSAGE: Proof of concept of Bayesian integrated QTL analyses across pedigree-related families from breeding programs of an outbreeding species. Results include QTL confidence intervals, individuals' genotype probabilities and genomic breeding values. Bayesian QTL linkage mapping approaches offer the flexibility to study multiple full sib families with known pedigrees simultaneously. Such a joint analysis increases the probability of detecting these quantitative trait loci (QTL) and provide insight of the magnitude of QTL across different genetic backgrounds. Here, we present an improved Bayesian multi-QTL pedigree-based approach on an outcrossing species using progenies with different (complex) genetic relationships. Different modeling assumptions were studied in the QTL analyses, i.e., the a priori expected number of QTL varied and polygenic effects were considered. The inferences include number of QTL, additive QTL effect sizes and supporting credible intervals, posterior probabilities of QTL genotypes for all individuals in the dataset, and QTL-based as well as genome-wide breeding values. All these features have been implemented in the FlexQTL(™) software. We analyzed fruit firmness in a large apple dataset that comprised 1,347 individuals forming 27 full sib families and their known ancestral pedigrees, with genotypes for 87 SSR markers on 17 chromosomes. We report strong or positive evidence for 14 QTL for fruit firmness on eight chromosomes, validating our approach as several of these QTL were reported previously, though dispersed over a series of studies based on single mapping populations. Interpretation of linked QTL was possible via individuals' QTL genotypes. The correlation between the genomic breeding values and phenotypes was on average 90 %, but varied with the number of detected QTL in a family. The detailed posterior knowledge on QTL of potential parents is critical for the efficiency of marker-assisted breeding.

[Evaluation of multidrug-resistant tuberculosis treatment in Ivory Coast from 2008 to 2010]. / Évaluation du traitement de la tuberculose multi-résistante en Côte d'Ivoire de 2008 à 2010.

This is a retrospective study conducted from January 2008 to December 2010 on sectional descriptive analysis of records of patients treated for MDR-TB and whose follow-up was in the thoracic department of Centre Hospitalier Universitaire (CHU) of Cocody in Abidjan Côte d'Ivoire. We selected eight patients who met the inclusion criteria of 21 MDR-TB patients registered during the study period. The average age was 29.25years ranging from 21 to 39. Males accounted for 75% of the patients (6 males and 2 females). The students represented the professional social layer most affected with 37.5% of the patients. All patients had a history of tuberculosis and only one patient was HIV positive under anti-retroviral (zidovudin, lamivudin and efavirenz). All cultures found Mycobacterium tuberculosis. The resistance profile in addition to isoniazid and rifampicin, found two cases of resistance to ethambutol and streptomycin. The chest radiograph at the time of initiation of second-line treatment showed essentially excavations in 75% of cases and infiltrates in 25%. The lesions were bilateral in 7 of 8 patients (87.5%). The main side effects observed during treatment were limited to cochleovestibular disorders (2 patients) and neuropsychiatric disorders (2 patients) and digestive disorders in half of the patients with removal of the offending molecule kanamycin. After 24months of treatment, it was numbered five cures (62.5%), two failures and one death.

[Etiologies of non tuberculous empyema in adult patients infected with HIV in a service of pneumology, Abidjan (Ivory Coast)]. / Étiologies des pleurésies purulentes non tuberculeuses chez les patients adultes infectés par le VIH dans un service de pneumologie à Abidjan (Côte d'Ivoire).

OBJECTIVES: To identify the main bacteria that cause thoracic empyema of HIV-infected patients. METHODS: Retrospective study analyzing the etiology of thoracic empyema in patients admitted to the pneumology clinic of the university hospital center in Abidjan from January 1998 to December 2010. We included all patients with bacteriologically confirmed thoracic empyema and had serological test for HIV. We compared the different pathogens based on HIV status. RESULTS: There were 42 patients of thoracic empyema composed of 24 (63.3%) HIV-infected patients [15 (62.5%) males and nine (37.5%) women] and 18 (36.7%) HIV-negative patients [13 (72.22%) men and five (27.78%) women]. The average age of HIV-infected patients was 41.2 years and 44.8 years for HIV-negative patients. HIV status was known only for 4.76% patients at admission, and most of them had a severe stage of immune suppression, (the average T CD4 cell count was 96/mm(3)). Pleurisy was monomicrobial in 83.33% HIV-infected patients and 94.4% HIV-negative patients. It was polymicrobial in 16.67% immunocompromised patients and 5.56% HIV-negative patient. Gram-negative bacteria were isolated from 58.33% HIV-infected patients. Streptococcus Pneumoniae was observed in 61.11% HIV-negative patients.

[Tolerance and Acceptability of Gastroscopy in Adults in Ivory Coast: 300 Cases]. / Tolerance et Acceptabilite de la Gastroscopie Chez L'Adulte en Cote D'Ivoire a Propos de 300 cas.

The purpose of this study was to report the real-life experience of oesophagogastroduodenoscopy (OGD) patients in order to note apprehensions and postoperative feedback. This prospective study involving 300 patients of the Cocody Teaching Hospital, was carried out over a four month period. It included 158 men and 142 women with an average age of 40 years. OGD was performed on outpatients (78%) and hospitalized patients (22%). The feelings of patients before EGD were marked by anxiety (91%) or serenity (9%). 88% of the patients received premedication versus 12% who did not. This premedication was based on midazolam in 69.31% of cases and diazepam in 30.69%. No incident or accident related to the procedure or to the premedication was reported. The tolerance of the patients regarding OGD, as reported by the patients and doctors, was good (78% vs 78% respectively), acceptable (17% vs 16.67%) or bad (5% vs 5.33%). Patients found the examination to be unpleasant (43.34%), painful (30.33%) or painless (26.33%). Doctors reported that patients' attitudes were marked by anxiety (91%) and serenity (9%). Age, sex, previous information on the examination, psychological preparation, the feelings of the patients before the examination and premedication with hypnovel or valium did not influence the tolerance of patients since the differences were not statistically significant (p>0.05). 89.33% of our patients would accept a repeat of the digestive endoscopy versus 10.67% who would not. Almost all the patients (99.33%), would recommend an OGD to another person versus only 0.67% who would not. 83.33% of patients were satisfied with the OGD versus 16.67% who were not.The OGD remains bearable with 78% of patients presenting a good tolerance despite the important number of patients (91%) who felt anxious before the examination.

Le but de cette étude était de rapporter le vécu de la FOGD par les patients afin de vérifier la véracité des appréhensions. Cette étude prospective portant sur 300 patients recensés au CHU Cocody d'Abidjan, a été réalisée sur une période de quatre mois. Elle regroupait 158 hommes et 142 femmes, d'âge moyen de 40 ans. La FOGD était réalisée chez des patients vus en ambulatoire (78%) ou hospitalisés (22%). Les sentiments des patients avant la FOGD étaient marqués par l'anxiété (91%) ou la sérénité (9%). 88% de nos patients ont reçu une prémédication versus 12% sans prémédication. Cette prémédication était à base de midazolam (69,31%) ou de diazépam (30,69%). Aucun incident ou accident lié au geste ou à la prémédication n'a été rapporté. La tolérance de la FOGD selon les patients était superposable à celle selon les médecins : bonne (78% vs 78%), acceptable (17% vs 16,67%) ou mauvaise (5% vs 5,33%). Les patients avaient trouvé l'examen désagréable (43,34%), douloureux (30,33%) ou indolore (26,33%). Les attitudes des patients selon les médecins ont été marquées par l'anxiété (91%) ou la sérénité (9%). L'âge, le sexe, les informations antérieures sur l'examen, la préparation psychologique, les sentiments des patients avant l'examen et la prémédication à l'hypnovel ou au valium n'influenceraient pas la tolérance des patients puisque les différences observées n'étaient pas statistiquement significatives (p > 0,05). 89,33% de nos patients accepteraient de refaire une endoscopie digestive versus 10,67% d'avis défavorable. La quasi-totalité de nos patients soit 99,33% recommanderaient une FOGD à une autre personne contre seulement 0,67%. 83,33% des patients étaient satisfaits de la FOGD contre 16,67% qui ne l'étaient pas.La FOGD reste tout de même supportable avec 78% des patients présentant une bonne tolérance malgré le grand nombre qui étaient anxieux avant l'examen 91%.
