A Case of Multiple Sclerosis to Gabon: Myth or Reality!  [PDF]
Ibrahima Aissata Camara, Lansana Laho Diallo, Philomène Kouna Ndouongo
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105592
Abstract:
Introduction: Multiple sclerosis is a neuro-inflammatory demyelinating disease rare in Africa south of the Sahara. Objective: The objective of this work is to describe multiple sclerosis in African black women from Gabon and to list the principles of care. Observation: We report the case of a Gab-onese girl, 21 years old, with no particular history, who had multiple scle-rosis following a decrease in visual acuity for six months associated with tingling and motor deficit of the lower right limb. Protein electrophoresis and cerebral magnetic resonance imaging (MRI) advocated multiple sclerosis. Conclusion: This observation highlights the fact that multiple sclerosis is a rare condition in black African countries and its discovery must always be considered as a diagnosis of elimination.

Abstract:
Objective: To determine the prevalence of headaches among Libreville teachers. Introduction: Headaches, commonly referred to as “headaches”, correspond to all the unpleasant sensations felt in the head. It is generally a question of subjective manifestations that only the patient can express. The most common functional sign is pain, which in itself is difficult to measure. Methodology: This is a cross-sectional prospective study with analytical and descriptive aims, which took place over a period of 4 months from February 1st to June 1st, 2016. It took place in five public secondary schools in two of the six districts of Libreville. Was considered cephalalgic (or suffering from headache), any teacher who answered “Yes” to the question: “Are you prone to headaches?” The choice of the reference interval to be able to evaluate the working time of the recruited teachers was inspired by the European standards which globally place the average weekly working time of teachers between 30 and 40 hours. The collected data were processed and analyzed with Epi-info 7 and SPSS 22 software. A regression analysis was performed to identify the associated factors. Results: We collected 236 teachers whose average age was 43.2 ± 7.9 years, with extremes of 27 and 60 years. There were 141 men (59.7%) and 95 women (40.3%) with a sex ratio of 0.96. The prevalence of headache was 76.7%. The factors associated with headaches were the subject taught, the number of students, and the provision of private tutoring. Five main triggers were found: overwork (86.2%), lack of sleep (84.5%), sun (73.5%), noise (68%) and fatigue (64.6%). The effects of headache were discomfort in daily activities (65.7%), absenteeism (35.9%) and a reduction in sleep time. Conclusion: Our study shows that headaches particularly affect the teaching profession with female predominance due to stressful situations caused by their work environment.

International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.69081
Abstract: The objective of this work is to analyze the spatial distribution of biases of nine (9) regional climate models (RCMs) and their ensemble average used under the framework of COordinated Regional climate Downscaling EXperiment (CORDEX) project over West Africa during the summer period. We assessed the ability of RCMs to represent adequately West African summer rainfall by analyzing some statistical parameters such as the relative bias, the standard deviation, the root mean square error (RMSE) and the correlation coefficient between observation data (GPCP used as reference) and regional climate models outputs. We first analyzed the relative bias between GPCP climatology and the other available observed data (CRU, CMAP, UDEL, GPCC, TRMM and their ensemble mean). This analysis highlights the big uncertainty on the quality of these observed rainfall data over West Africa which may be largely due to the rarity ofin situmeasurement data over this region. The statistical analysis with respect to GPCP rainfall shows the presence of large relative bias values over most part of West Africa for engaged RCMs. However their ensemble mean outperforms individual RCMs by exhibiting the weakest relative change. The RMSE values are weak over West Africa except over and off the Guinea highlands for RCMs and the Era-interim reanalysis. The spatial distribution of the coefficient of correlation between the observation data and RCMs shows that all models (except HIRHAM) present positive values over the Northern Sahel and the Gulf of Guinea. The model of the DMI exhibits the weakest values of correlation coefficient. This study shows that RCMs simulate West African climate in a satisfactory way despite the fact that they exhibit systematic biases.
Impacts of the Sahel-Sahara Interface Reforestation on West African Climate: Intra-Annual Variability and Extreme Temperature Events  [PDF]
Ibrahima Diba, Moctar Camara, Arona Diedhiou
Atmospheric and Climate Sciences (ACS) , 2019, DOI: 10.4236/acs.2019.91003
Abstract: The impacts of the reforestation of the Sahel-Sahara interface on the seasonal distribution of the surface temperature and thermal extremes are studied in the Sahel (West African region lying between 11°N and 18°N). We performed a simulation with the standard version of the RegCM4 model followed by another one using the altered version of the same model taking into account an incorporated forest. The impacts of the vegetation change are assessed by analyzing the difference between the two runs. The reforestation may influence strongly the frequency of warm days (TG90P) and very warm days (TX90P) by decreasing it over the reforested zone from March to May (MAM) and the entire Sahel during the June-August (JJA) period. These TG90P and TX90P indices decrease may be due to the strengthening of the atmospheric moisture content over the whole Sahel region and the weakening of the sensible heat flux over the reforested zone. The analysis also shows a decrease of the TN90P indice (warm nights) over the Sahel during the wet season (JJA) which could be partly associated with the strengthening of the evapotranspiration over the whole Sahel domain. The analysis of additional thermal indices shows an increase of the tropical nights over the entire Sahel from December to February (DJF) and during the warm season (MAM). The strengthening of the tropical night is partly associated with an increase of the surface net downward shortwave flux over the reforested zone. When considering the heat waves, an increase (a decrease) of these events is recorded over the southern Sahel during JJA and SON periods (over the whole Sahelian region during DJF), respectively. Changes in latent heat flux appear to be largely responsible for these extreme temperatures change. This work shows that the vegetation change may impact positively some regions like the reforested area by reducing the occurrence of thermal extremes; while other Sahel regions (eastern part of the central Sahel) could suffer from it because of the strengthening of thermal extremes.
Vertical Price Transmission in Local Rice Markets in Cote d'Ivoire: Are Consumers Really Right?
Yaya KEHO,Aissata SOBIA CAMARA
Asian Journal of Agriculture and Rural Development , 2012,
Abstract: This paper analyses vertical relationships between wholesale and retail prices in three local rice markets in C te d’Ivoire. The aim of the paper is to ascertain whether the popular complaint of consumers about the asymmetric price transmission holds true. Our empirical analysis makes use of threshold cointegration and error correction models and monthly data for the period 1990-1999. We found that wholesale and retail prices are cointegrated and increases in wholesale prices are passed on to retail prices more quickly than decreases.

Abstract:

An old woman, 28 years old, weighing 74 kg was referred for skin detachment associated with bubbles and mucosal erosions. This clinical picture had occurred 15 days after the institution of a triple combination: AZT (300 mg) + 3TC (150 mg) and nevirapine (200 mg), during a pregnancy of 20-week gestation. The woman was in her third gestation. The second case is aged 26, weighing 65 kg. This clinical picture had occurred 20 days after the administration of a triple therapy combination: AZT (300 mg) + 3TC (150 mg) and nevirapine (200 mg), during a pregnancy of 32-week gestation. It was the fourth gestation. The birth of a stillborn had occurred the day before his admission into our service. The diagnosis of Toxic Epidermal Necrolysis with nevirapine was selected on the basis of the clinical and anamnestic arguments. The biological tests showed the following results: transaminases (ALT and AST) were within normal limits, blood glucose, and urea > 10 mmol/l. The evolution was marked by the patient death to Day 9 (D9) and at D2 of hospitalization. Discussion: NET and the SJS have been reported in pregnant women as potentially dangerous complications that are often associated with suspected drugs. Among these drugs, antiretroviral drugs, prescribed to pregnant women to prevent mother to child transmission of HIV are often reported. Our case is an illustration of the problem of HIV management in pregnant women. It also focuses on the association between pregnancy and Toxic Epidermal Necrolysis. Nevirapine is an effective drug in the regimens proposed in the management of HIV patients in limited resources countries. But the high frequency of toxidermia with this drug should lead to its replacement by other antiretrovirals least providers of toxidermia as anti proteases in the context of PMTCT programs.

Abstract: Severe drug reactions are defined as mucocutaneous complications secondary to systemic administration of drugs likely to be life threatening. Our work was designed to determine the evolutionary epidemiological and etiological characteristics of severe drug reactions to the Department of Dermatology Venereology, at Donka Teaching Hospital. A prospective descriptive study of all cases of severe drug reactions received at the Department of Dermatology Venereology of the Donka Teaching Hospital was conducted over a period of two years, from June 2009 to May 31, 2011. We identified 22 Stevens-Johnson syndrome, 13 Toxic Epidermal Necrolysis, 1 Stevens-Johnson syndrome Border Toxic Epidermal Necrolysis, 1 Drug Rash with Eosinophilia and Systemic Symptoms and 2 Acute generalized exanthematous pustulosis among 481 hospitalized patients, of whom 50 had consulted for drug reactions, that is to say, a frequence of 10.40%. The Stevens-Johnson syndrome accounted for 44%, the Stevens-Johnson syndrome Border Toxic Epidermal Necrolysis 2%, Toxic Epidermal Necrolysis 26%, Drug Rash with Eosinophilia and Systemic Symptoms 2% and Acute generalized exanthematous pustulosis 4% of drug reaction. The female sex was predominant (28 women vs. 11 men), that is to say 71.59% vs. 26.21 with a sex ratio of 2.55. The average age of our patients was 29.72 years; the range of ages 21 - 40 years was the most affected (51.28%) followed by 0 - 20 years (33.33%). The lethality rate was 9.09% (2/22) in the Stevens-Johnson syndrome and 53.85% (7/13) in the Toxic Epidermal Necrolysis. HIV infection was found in 17.95% (7/26) of our patients and 71.42% (5/7) of the deceased. The drug accountability was established in 79.48%; the most commonly implicated drugs in the Toxic Epidermal Necrolysis were sulfonamides followed by ARVs (nevirapine) and anti TB (isoniazid); in the SJS sulfonamides followed by salts of quinine and anti TB, the only case of DRESS was due to quinine. No drug was found in 20.52% (8 cases). HIV infection remains a poor prognostic factor. Our study shows the scarcity of Drug Rash with Eosinophilia and Systemic Symptoms and Acute generalized exanthematous pustulosis in our service.

World Journal of Cardiovascular Diseases (WJCD) , 2018, DOI: 10.4236/wjcd.2018.81005
Abstract: Background: Traditional cardiovascular risk factors (CVrf) like hypertension, diabetes, dyslipidemia, obesity, smoking have been studied extensively through theses in hospital studies. Therefore, recent published data from community based studies are rare in Mali. Available data are old justifying to perform a community based study on traditional CVrf in rural and urban areas. Materials and Methods: We retrospectively performed a study which data stemmed from the last STEPS survey carried out in 2013 in some rural and urban areas of Mali. We studied hypertension, diabetes, tobacco smoking, obesity based on body mass index, waist circumference and waist-to-hip ratio. After bivariates analyses, we conducted a logistic regression with rural/urban as dependent variable using SPSS as analysis software for this purpose. Results: Weight, height, WC and HC were higher in urban area with 69.77 Kg, 169.13 cm, 85.98 cm and 97.26 cm compared to 66.27, 165.42, 81.46 and 93.23 in rural area (p < 0.001). We had more female in rural area and educational level was higher in urban area. In bivariate analysis obesity based on BMI, WC, alcohol consumption was more prevalent in urban area while elevated waist-to-hip ratio was more prevalent in rural area. But in logistic regression for female, the Odds for Tobacco smoking rural as reference was 0.334 [CI: 0.151 - 0.738] (p = 0.007) and that for WHr is 0.582 [CI: 0.415 - 0.815] (
