    Case Report Multifocal Buruli Ulcer Associated with Secondary Infection in HIV Positive Patient

    Get PDF
    Buruli ulcer is a chronic and infectious skin disease, caused by Mycobacterium ulcerans. It leads to large skin ulceration and sometimes bone infection which is responsible for deformities. Here, we report a case of multifocal form of Buruli ulcer associated with secondary infection in a 46-year-old human immunodeficiency virus (HIV) positive woman. The antimycobacterial drugs combined to surgery allowed curing this multifocal case and rose up two relevant issues: the susceptibility of immune reconstitution inflammatory syndrome (IRIS) occurrence and Mycobacterium dissemination. The deep immune depression, the underline biological, and clinical disorders of the patient might contribute to IRIS occurrence and Buruli ulcer dissemination. Future investigations have to be conducted on the mechanism of IRIS on set and on Mycobacterium ulcerans dissemination after ARV drugs initiation and the patient related underline clinical or biological disorders

    The specific objectives were to identify the epidemiology of cutaneous sarcoidosis and describe the clinical and laboratory aspects of the disease. Materials and Methods. We performed a descriptive cross-sectional study involving 24 referred cases of cutaneous sarcoidosis in 25 years (1990–2014) collected at Venereology Dermatology Department of the University Hospital of Treichville (Abidjan) both in consultation and in hospitalization. Results. The hospital frequency was one case per year. The average age was 42 years, ranging from 9 to 64. The sex ratio was 1. The shortest time interval between the appearance of the skin lesion and consultation of Dermatology Department at CHU Treichville was 3 months. The elementary lesions were represented primarily by a papule (18 cases), placard (3 cases), and nodule (2 cases) and mainly sat on the face and neck in 8 cases (38%). Extra cutaneous lesions were dominated by ganglion and respiratory involvement with 5 cases each followed by musculoskeletal damage in 3 cases. Chest radiography showed abnormality in 13 cases (54%). The pulmonary function test performed in 13 patients found 7 cases (54%) having restrictive ventilatory syndrome and 6 cases (46%) being normal. A tuberculin anergy was found in 11 cases (61%)

    BACKGROUND: In sub-Saharan Africa, the burden of human immunodeficiency virus (HIV)-associated tuberculosis is high. We conducted a trial with a 2-by-2 factorial design to assess the benefits of early antiretroviral therapy (ART), 6-month isoniazid preventive therapy (IPT), or both among HIV-infected adults with high CD4+ cell counts in Ivory Coast. METHODS: We included participants who had HIV type 1 infection and a CD4+ count of less than 800 cells per cubic millimeter and who met no criteria for starting ART according to World Health Organization (WHO) guidelines. Participants were randomly assigned to one of four treatment groups: deferred ART (ART initiation according to WHO criteria), deferred ART plus IPT, early ART (immediate ART initiation), or early ART plus IPT. The primary end point was a composite of diseases included in the case definition of the acquired immunodeficiency syndrome (AIDS), non-AIDS-defining cancer, non-AIDS-defining invasive bacterial disease, or death from any cause at 30 months. We used Cox proportional models to compare outcomes between the deferred-ART and early-ART strategies and between the IPT and no-IPT strategies. RESULTS: A total of 2056 patients (41% with a baseline CD4+ count of ≄500 cells per cubic millimeter) were followed for 4757 patient-years. A total of 204 primary end-point events were observed (3.8 events per 100 person-years; 95% confidence interval [CI], 3.3 to 4.4), including 68 in patients with a baseline CD4+ count of at least 500 cells per cubic millimeter (3.2 events per 100 person-years; 95% CI, 2.4 to 4.0). Tuberculosis and invasive bacterial diseases accounted for 42% and 27% of primary end-point events, respectively. The risk of death or severe HIV-related illness was lower with early ART than with deferred ART (adjusted hazard ratio, 0.56; 95% CI, 0.41 to 0.76; adjusted hazard ratio among patients with a baseline CD4+ count of ≄500 cells per cubic millimeter, 0.56; 95% CI, 0.33 to 0.94) and lower with IPT than with no IPT (adjusted hazard ratio, 0.65; 95% CI, 0.48 to 0.88; adjusted hazard ratio among patients with a baseline CD4+ count of ≄500 cells per cubic millimeter, 0.61; 95% CI, 0.36 to 1.01). The 30-month probability of grade 3 or 4 adverse events did not differ significantly among the strategies. CONCLUSIONS: In this African country, immediate ART and 6 months of IPT independently led to lower rates of severe illness than did deferred ART and no IPT, both overall and among patients with CD4+ counts of at least 500 cells per cubic millimeter.

    Latitudinal and seasonal variability of the mixed layer depth (MLD) was investigated using hydrological data from several oceanographic databases collected over the period from October 1973 to March 2017 at 10 °W between latitudes 2 °N and 10 °S in the Gulf of Guinea. The density threshold method with a criterion of 0.03 kg m-3 was used to estimate the MLD. In the equatorial band, the seasonal mean MLD is 20 m regardless of the season. At 6 °S and 10 °S, the MLD is relatively higher during the cold season. The MLD varies between 21 and 40 m at 6 °S, and the seasonal mean of MLD are 28 and 32 m during the warm and cold seasons, respectively. At 10 °S, during the warm season, the MLD varies between 28 and 52 m, and the seasonal mean is 40 m. During the cold season, the MLD varies between 45 and 55 m with a seasonal mean of 50 m. The combination of historical and recent CTD profile data of temperature, salinity and nitrate collected over three decades from 1973 to 2007 in the tropical Atlantic Ocean was used to study the seasonal surface nitrate supply as a function of nitracline and MLD depth in the tropical Atlantic at 10 °W between 2 °N and 10 °S. The results reveal that in the equatorial zone despite relatively low MLDs in the cold season, a shallow mixed layer (10> MLD> 30 m)was observed between the equator and 2 °S with mean contents of 2.06 mmol m-3 of elevated nitrate. In contrast to the 0-2 °S zone, north of the equator (0-2 °N) while the MLDs become shallower, nitrate concentrations decrease and tend towards zero levels at 2 °N in the mixed layer (ML). During the warm season, an influx of nitrate associated with a deep ML is observed in the equatorial zone. Along with this nitrate availability in the sea surface layer, elevated nitracline is reported both in the ML and below the ML. Meanwhile, nitrate concentrations are very high with a maximum of 7.8 mmol m-3 in the ML at 1°N and 1°S around 8 m depth. In areas south of the equator (5-10 °S) despite the observed deepening of the ML, low nitrate concentrations are observed with nitracline not reaching the ML. However, at 6 °S there is an increase in nitrate content of 0.67 mmol m-3 followed by a sharp increase of 5.41 mmol m-3 at 8 °S at about 42 m depthLa variabilité latitudinale et saisonniÚre de la profondeur de la couche de mélange (MLD) a été étudiée à l'aide des données hydrologiques de plusieurs bases de données océanographiques recueillies sur la période d'octobre 1973 à mars 2017 à 10 °W entre les latitudes 2 °N et 10 °S dans le Golfe de Guinée. La méthode du seuil de densité avec un critÚre de 0,03 kg m-3 a été utilisée pour estimer la MLD. Dans la bande équatoriale, la MLD moyenne saisonniÚre est de 20 m quelle que soit la saison. A 6 °S et 10 °S, la MLD est relativement plus élevée pendant la saison froide. La MLD varie entre 21 et 40 m à 6 °S, et les moyennes saisonniÚres de MLD sont respectivement de 28 et 32 m pendant les saisons chaude et froide. A 10 °S, pendant la saison chaude, la MLD varie entre 28 et 52 m, et la moyenne saisonniÚre est de 40 m. Pendant la saisonfroide, la MLD varie entre 45 et 55 m avec une moyenne saisonniÚre de 50 m. La combinaison des données historiques et récentes des profils CTD de température, de salinité et de nitrate collectées pendant plus de trois décennies de 1973 à 2007 dans l'Océan Atlantique tropical a été utilisée pour étudier l'approvisionnement saisonnier de surface en nitrate en fonction de la nitracline et de la profondeur de la MLD dans l'Atlantique tropical à 10 °W entre 2 °N et 10 °S. Les résultats révÚlent que dans la zone équatoriale malgré des MLD relativement faibles en saison froide, une couche de mélange peu profonde (10> MLD> 30 m) a été observée entre l'équateur et 2 °S avec des teneurs moyennes élévées de 2,06 mmol m-3 de nitrate. Contrairement à la zone 0-2 °S, au nord de l'équateur (0-2 °N) pendant que les MLD deviennent moins profondes, les concentrations de nitrate diminuent et tendent vers des teneurs nulles à 2 °N dans la couche de mélange (ML). Pendant la saison chaude, un apport de nitrates associé à une ML profonde est observé dans la zone équatoriale. ParallÚlement à cette disponibilité de nitrate dans la couche de surface de la mer, une nitracline élevée est signalée à la fois dans la ML et en dessous de la ML. Pendant ce temps, les concentrations de nitrate sont trÚs élevées avec un maximum de 7,8 mmol m-3 dans la ML à 1 °N et 1 °S autour de 8 m de profondeur. Dans les zones au sud de l'équateur (5-10 °S) malgré l'approfondissement observé de la ML, de faibles concentrations de nitrate sont observées avec une nitracline qui n'atteint pas la ML. Cependant, à 6 °S, une augmentation de la teneur en nitrates de 0,67 mmol m-3 suivie d'une forte augmentation de 5,41 mmol m-3 à 8 °S aux environs de 42 m de profondeur est observée

    Eastern Tropical Atlantic Mixed Layer Depth: Assessment of Methods from In Situ Profiles in the Gulf of Guinea from Coastal to High Sea

    No full text
    WOS:000502584900001International audienceTo assess the eastern Atlantic tropical mixed layer depth (MLD) at 4 degrees W in the Gulf of Guinea, water temperature and density profiles from over five hundred historical observational Conductivity - Temperature - Depth (CTD) data were used. These data, obtained from key oceanographic survey databases covering 60 years (1956 to 2016) were used for a numerical and visual determination of the MLD. The numerical approach consists of the use of the algorithms of three methods; while the visual estimation of the MLD were made on both temperature and density profiles. The numerical approaches were evaluated by comparing their results on the determination of tropical MLD with those of the visual inspections by means of statistical and graphical analysis in order to determine the most suitable method for the determination of MLD in the study area. Our results show that the Boyer Montegut density threshold method (potential density) with the constant criterion Delta sigma = 0.03 kg.m(-3) and a reference depth of ten meters is the most appropriate for determining the MLD in the Gulf of Guinea regardless the season. However, in the situation where only temperature profiles are available it is advisable to estimate MLD using the Lorbacher curvative method
