We present a study of the substrate influence on the buffer layer morphology, on the static magnetic properties and especially on the magnetization reversal dynamics in 1 nm thick cobalt layer of Au/Co/Au system. In all films the cobalt layer exhibits perpendicular magnetic anisotropy. The magnetization reversal process has been investigated by polar magnetooptic Kerr effect (PMOKE). It was found that magnetization reverses by domain wall propagation. A simplified form of the Fatuzzo-Labrune model was used to interpret the magnetization reversal. Correlation between magnetic and morphologic results is discussed. © 2013 Elsevier B.V. All rights reserved.

Objective: The aim of this study was to document the causes of death in the dermatology department in Lomé and the role of HIV infection in those deaths. Patients and method: This retrospective study examined the records of all patients admitted to this department from 1992 through 2012. Results: During the study period, 52 (13.5%) of the 386 patients hospitalized in the Sylvanus Olympio University Hospital dermatology department died in the hospital. Their mean age was 37.7 ± 12.8 years (range: 18 to 68 years) and half (26 patients/52) were female. Kaposi’s sarcoma (54.1%) was the most lethal skin disease, followed by cutaneous drug reactions (12.5%) and herpes zoster virus infection (11.1%). Of the 52 patients who died, HIV serology was positive in 28 of the 33 (84.8%) patients tested. The most lethal diseases, including Kaposi’s sarcoma, Stevens-Johnson syndrome (toxic epidermic necrolysis), and chicken pox/shingles skin diseases were those in which HIV seroprevalence was highest. Conclusion: This study shows that HIV infection plays an important role in mortality in the dermatology department at Lomé, probably through the immunosuppression it induces. © 2015, John Libbey Eurotext.

The dibi-madibi is a mode of tenure that allowed quick indirect ownership of farm space by the population in the south-west of Togo at the beginning of the development of coffee and cocoa plantations. This mode of tenure profited farmers who were mostly from the north of the country. They acquired the ownership right to half of the plot of land that was actually developed. That transmissible right cannot be compared, at the legal level, to the traditional contracts known in Togo. That right should not be confused with either the classical rent or sharecropplng. Today, this original agrarian land ownership practice creates a number of problems between the former landowners and the exploiters. The former resent the acquisition in full ownership of half of the developed land by the latter and are tempted to challenge that acquisition, which causes conflict between them.

The absence of good system for collection, storage and disposal of solid waste in the city of Kara who is built on the catchment area of the river Kara contributes to the degradation of water quality of this river. Pollution of surface waters is generally identified by the accumulation of metal components in sediments. The objective of this study is to use the distribution of organic matter in the matrix, waste, water and sediments as an indicator to assess the contribution of solid waste in the degradation of the quality of this river. Besides the conventional parameters to characterize organic matter, fractionation based on hydrophobic is used to better correlate the organic matter in water and waste. Sediments collected in the urban area have the highest organic matter content and greater facility to release the accumulated organic matter. Finally, monitoring the quality of organic matter in different matrix according to its hydrophobic nature and according to its apparent molecular weight (LDCs) confirms the waste impact on the quality of the river. © EuroJournals Publishing, Inc. 2012.

Objective. To evaluate the monitoring of HIV-infected children receiving antiretroviral therapy in rural areas of Togo and the effectiveness of the treatment. Methods. This retrospective descriptive study, conducted at the Luis Scrosospi Center in Kouvé from 15 November, 2008, through 14 November, 2009, examined the records of children who had been receiving antiretroviral therapy for at least 6 months. Results. We studied the records of 55 children. The sex ratio was 0.9, and the primary opportunistic infections were respiratory infections and malaria. At treatment initiation, their average age was 6 years and 3 months, the average CD4 T cell count 358/mm3, and the mean weight 12.9 kg. The hemoglobin level was less than 8 g/dL in 31%. All children received a nutritional kit monthly. The antiretroviral therapy for 52 children was a combination of stavudine, lamivudine, and nevirapine. The adherence rate during the first 12 months was 80% (44/55 children). The mean weight gain was 860 g (below -3SD) at 3 months, 1,550 g (between -3SD and -2SD) at 6 months, and 1 270 g (between -2SD and -1SD) at 12 months of treatment. The severe acute malnutrition rate fell from 60% at treatment initiation to 56% at 3 months, 47% at 6 months, and 25% at 12 months. Also after 12 months, the CD4 T cell count had risen in 60% of the children. The main side effects were peripheral neuropathy (29%) and headaches (18%). Eight children died (14%) during the follow-up. Conclusion. Monitoring of HIV-infected children on antiretroviral therapy is possible in Togo's rural areas and should be encouraged for it will help to achieve the Millennium Development Goals.
