Abstract:

Lhermitte-Duclos disease (LDD) or dysplastic gangliocytoma of the cerebellum is a rare benign lesion of uncertain pathogenesis characterized by overgrowth of cerebellar ganglion cells which replace granular cells and Purkinje cells; this results in gross thickening of the cerebellar folia. It is revealed by symptoms of raised intracranial pressure, cerebellar impairment and obstructive hydrocephalus. We reported the case of a 41-year-old male who presented with symptoms of acute raised intracranial pressure. Brain computed tomography (CT) scan revealed hydrocephalus due to compression of the 4th ventricle by a large non-enhancing left cerebellar mass. Magnetic resonance imaging (MRI) showed a space-occupying lesion within the left cerebellar hemisphere with unusual striation. Radical surgery was retained though the margins with normal cerebellar tissue were not distinct. Clinical complications after gross total or partial removal of Lhermitte-Duclos lesions have been rarely reported in the literature; herein we stress the importance of extreme caution in removing these lesions in cerebellar areas that have no distinct margins between the lesion and normal tissue.

Abstract: Background: Hemorrhoidal disease is most frequently encountered in proctology affection; it is defined by signs or symptoms attributed to hemorrhoids. Its pathogenesis is based on old theories and vascular mechanical which are nevertheless based on the current therapeutic approach. General Aim of the Study: To study haemorrhoids’ pathology in order to improve its management. Methodology: A retrospective cross-sectional study was conducted over a period of two (2) years from 1 January 2012 to 31 December 2013. Data were collected from outpatients records in hepato-gastroenterology and digestive surgery services at “Polyclinique Notre Dame de la Paix” in Ouagadougou (2294 files). Results: 140 cases of haemorrhoids were recorded during our study period. The frequency was 6.1% of consultations. Males predominated with 75.71% of patients (sex ratio = 3.12). The average age was 39.58 years. Civil servants were most affected by this disease (60%). Rectal bleeding was the most common reason of consultation (52.14%). The crown shape was predominated (59%). The frequency of external haemorrhoids was the highest (65.71%) and stage 4 (40.79%) was the most represented. Anal fissure was the proctologic pathology, the most associated to haemorrhoids (17.14%). Medical treatment concerned 89.28% of patients with 69.6% of favorable short-term evolution. No instrumental treatment was performed. Surgical treatment consisted of 10.71% of patients and the technique used was the Milligan-Morgan performed under spinal anesthesia. The postoperative complications were mainly represented by anal intense pain and acute urinary retention. The healing period of wounds was on average 6 weeks. Conclusion: The hemorrhoid has often underestimated in our regions. The instrumental treatment is nonexistent and should take an important place; it must be an indication before surgery.

Abstract: The aim of this work was to assess the preliminary anatomical and functional results of patients to establish prospects. Materials and method: We report here the preliminary results of a retrospective mono-centric, homogeneous and continuous series, of 21 non-cemented total hip implants, implanted from January 2011 to December 2014. The mean follow-up time was 24 months. The patients were evaluated by Harris’s hip at the last follow-up. Results: The mean age of the intervention was 30 years. In our series, we observed a male predominance (60% of cases). Clinically, the Harris score varied significantly from 52.6 ± 11.4 pre-operatively to 85.1 ± 5.1 during the last follow-up visit. Among the items in the score, pain was the parameter that showed the greatest improvement. Thigh pain was observed in only one patient operated on the two sides. At the level of radiology, the femoral implant showed great stability. Bone resorption was suspected in 14 cases (66.66%), and confirmed in 4 cases (19.04%) with excellent bone remodeling, illustrated by the Engh and Massin scores. A loosening and a prosthetic dislocation was observed in a patient (4.76%). Any heterotopic ossification was observed. Conclusion: Our study confirmed good clinical and radiological results of the non-cemented hip prosthesis series in young patients. The rates of aseptic loosening, acetabular edges or osteolysis are low and stable over time.

Hydrology and Earth System Sciences (HESS) & Discussions (HESSD) , 2013, DOI: 10.5194/hess-17-1589-2013
Abstract: This paper introduces and describes the hourly, high-resolution soil moisture dataset continuously recorded by the McMaster Mesonet located in the Hamilton-Halton Watershed in Southern Ontario, Canada. The McMaster Mesonet consists of a network of time domain reflectometer (TDR) probes collecting hourly soil moisture data at six depths between 10 cm and 100 cm at nine locations per site, spread across four sites in the 1250 km2 watershed. The sites for the soil moisture arrays are designed to further improve understanding of soil moisture dynamics in a seasonal climate and to capture soil moisture transitions in areas that have different topography, soil and land cover. The McMaster Mesonet soil moisture constitutes a unique database in Canada because of its high spatio-temporal resolution. In order to provide some insight into the dominant processes at the McMaster Mesonet sites, a spatio-temporal and temporal stability analysis were conducted to identify spatio-temporal patterns in the data and to suggest some physical interpretation of soil moisture variability. It was found that the seasonal climate of the Great Lakes Basin causes a transition in soil moisture patterns at seasonal timescales. During winter and early spring months, and at the meadow sites, soil moisture distribution is governed by topographic redistribution, whereas following efflorescence in the spring and summer, soil moisture spatial distribution at the forested site was also controlled by vegetation canopy. Analysis of short-term temporal stability revealed that the relative difference between sites was maintained unless there was significant rainfall (> 20 mm) or wet conditions a priori. Following a disturbance in the spatial soil moisture distribution due to wetting, the relative soil moisture pattern re-emerged in 18 to 24 h.

The sites for the soil moisture arrays are designed to further improve understanding of soil moisture dynamics in a cold and snowy climate and to capture soil moisture transitions in areas that have different topography, soil and land-cover. The McMaster Mesonet soil moisture constitutes a unique database in Canada because of its high spatio-temporal resolution. In order to provide some insight into the dominant processes at the McMaster Mesonet sites a spatio-temporal and temporal stability analysis were conducted to identify spatio-temporal patterns in the data and to suggest some physical interpretation of soil moisture variability. It was found that the seasonal Canadian climate causes a transition in soil moisture patterns at seasonal time scales. During winter and early spring months, and at the meadow sites, soil moisture distribution is governed by topographic redistribution, whereas following efflorescence in the spring and summer, soil moisture spatial distribution at the forested site was equally dominated by vegetation canopy. Analysis of short-term temporal stability revealed that the relative difference between sites was maintained unless there was significant rainfall (> 20 mm) or wet conditions a priori. Following a disturbance in the spatial soil moisture distribution due to wetting, the relative soil moisture pattern re-emerged in 18 to 24 h.

Abstract: Background. Since the treatment of hypertension is beneficial for the elderly, we have undertaken this study that aims to evaluate the management of hypertension in elderly patient in Côte d'Ivoire. Methods. A retrospective study was conducted among 854 hypertensive elderly patients of Abidjan Cardiology Institute who were followed for a minimum of one year, between January 2000 and December 2009. Results. The patients mean age was 73.1±5.3 years, and 59% were women. At the first presentation, it was mostly systolic-diastolic hypertension (51.8%) and isolated systolic hypertension (38.5%). Mean blood pressure was 169.4±28.4 mmHg for systolic, 95.3±15.7 mmHg for diastolic, and 74.1±22.8 mmHg for pulse pressure. Pulse pressure was ≥60 mmHg in 80.4%. According to the European Guidelines stratification of the cardiovascular risk-excess attributable to high blood pressure, 82.1% of the sample had a very high added risk. The pharmacological therapy was prescribed in 93.5%. More than 66% of patients were receiving ≥2 antihypertensive drugs including fixed-dose combination drugs. The most common agents used were diuretics (63.5%) followed by angiotensin-converting enzyme inhibitors or angiotensin receptor blockers in 61.3%. The most common agents used for monotherapy were calcium antagonists. When ≥2 drugs were used, diuretics and angiotensin-converting enzyme inhibitors or angiotensin receptor blockers were the most common. Blood pressure control was achieved in 42.6%. Conclusion. The control of elderly hypertension can be effective in Sub-Saharan Africa. He required at least two antihypertensive drugs to meet the recommended blood pressure target.

Abstract:
Introduction: Post-stroke depression occurs in a context of stroke characterized by sadness, loss of interest, feelings of guilt, loss of appetite, a feeling of tiredness, and a lack of concentration. Material and Methods: We conducted a descriptive cross-sectional study from January 1, 2013 to September 30, 2016. For the diagnosis of post-stroke depression, neuropsychological tests (DSM-IV and MADRS) were used. The collection approach was a maintenance survey followed by an examination. Results: From 153 stroke patients, 48.4% (n = 74) had post-stroke depression. Depressed mood was noted in 50.3% and 43.8% had a marked decrease in interest. 67.9% of these patients had a primary level of education. Widows had 4.2 times the risk of post-stroke depression, and married and retired patients were 3 times more likely than public servants. The occurrence of post-stroke depression was significantly related to the presence of motor deficit in our patients, p < 0.0001. Conclusion: These results suggest that the risk of developing depression after stroke increases with the motor deficit. The DSM-IV and MADRS scores remain neuropsychological examinations of choice for the diagnostic approach.

Abstract: Background: A cardiovascular assessment is rarely performed among athletes despite more and more frequently reported fatal events. Most of these accidents are of cardiovascular origin. Moreover, data on ECG or Echocardiography are rare in our context justifying our study to assess electrical and echocardiographic pattern among high-level footballer in Bamako. Methods: It was a cross-sectional study conducted in Bamako from April 2015 to?March 2016 among high-level footballers aged 14 to 35 years old without distinction of sex with at least 10 hours weekly training since one year. The ECG and echocardiographies were recorded respectively with a 12-lead CONTEC and an ATL 5000 echocardiographic machine. Each ECG record was analyzed by a cardiologist in accordance with the Seattle 2013 criteria and those pathological reviewed by a second cardiologist according to the same criteria and definitively classified as normal (physiological) or abnormal ECG (requiring complementary explorations). A third cardiologist was associated in case of discordance of the first results. The collected data were inserted in a Microsoft Excel sheet and analyzed with SPSS version 20. Chi Square and Fisher statistical tests were used to compare our results. The significance level was set at 0.05. Results: We collected data of 227 top footballers with male sex represented in 90.3% giving a sex ratio of 3.04. Means for age, weight, height, body mass index (BMI) were respectively 22 years, 69.90 kg, 177.21 cm and 22.21 kg/m2. Sinus bradycardia was found in a proportion of 45.8% more represented in the age group of 30 and more years (p = 0.275). First-degree atrioventricular block (AVB) was present in 19.4%. Short PR was found in 0.4% of the

Abstract: Anopheles funestus is a principal vector of malaria across much of tropical Africa and is considered one of the most efficient of its kind, yet studies of this species have lagged behind those of its broadly sympatric congener, An. gambiae. In aid of future genomic sequencing of An. funestus, we explored the whole body transcriptome, derived from mixed stage progeny of wild-caught females from Mali, West Africa.

Abstract: Between August 1996 and December 1998, direct and membrane feeding methods were compared for the infectivity of children and adolescent gametocyte carriers to anopheline mosquitoes in the village of Bancoumana in Mali. Gametocyte carriers were recruited twice a month through a screening of members of 30 families using Giemsa-stained thick blood smears. F1 generation mosquitoes issued from individual female wild mosquitoes from Bancoumana were reared in a controlled insectary conditions and fed 5% sugar solution in the laboratory in Bamako, until the feeding day when they are starved 12 hours before the feeding experiment. These F1 generation mosquitoes were divided in two groups, one group fed directly on gametocyte carriers and the other fed using membrane feeding method.Results from 372 Plasmodium falciparum gametocyte carriers showed that children aged 4–9 years were more infectious than adolescents (p = 0.039), especially during the rainy season. Data from 35 carriers showed that mosquitoes which were used for direct feeding were about 1.5 times more likely to feed (p < 0.001) and two times more likely to become infected, if they fed (p < 0.001), than were those which were used for membrane feeding. Overall, infectivity was about three-times higher for direct feeding than for membrane feeding (p < 0.001).Although intensity of infectivity was lower for membrane feeding, it could be a surrogate to direct feeding for evaluating transmission-blocking activity of candidate malaria vaccines. An optimization of the method for future trials would involve using about three-times more mosquitoes than would be used for direct feeding.Studies of vector-parasite relationships under field conditions have helped to identify human reservoirs of infection[1,2] host-, parasite-, and vector-based determinants of infection[3]; the natural efficiency of sporogonic development in the mosquito vector Anopheles gambiae[4]; and naturally occurring transmission-blocking antibodies [1,5-7
