Introduction: cervical spine trauma remains one of the most common causes of morbidity in the world with a significant financial burden on our society. It is a devastating event for the patient and family. The aim of this study is to share our experience in the surgery management of cervical spine injury in rural area. Methods: We did retrospective and single center study for one year from August 2020 to August 2021. We included all the patients who had undergone surgery for cervical spine injury in our hospital. Results: The study is based on 14 patients, 9 males and 5 females (sex ratio: 1.8). The average age was 34 years old and 08 (57%) were employed at time of injury. Road traffic accident was the most common cause, it was found in 11 (78%) cases followed by falls in 2 (14%) and interpersonal assault in 1 (7%). The Time admission ranged from 03 hours to 03 weeks. The most associated lesion was head trauma 7 (50%) followed by chest injury in 05 (35%) and 92% of our patient had motor deficit. Surgery was performed in all cases. Closed reduction was performed in 09 (64%) before surgery. Different types of complications that we had encountered were: infection 01 (07%) case, bed sores 02 (14%) cases, respiratory distress 02 (14%) cases and cervical kyphosis 01 (07%) case. After 06 months 71% of patients have progressed well with partial or complete recovery of their deficit. 14% of death in our series were noted and 28% of patients returned to work. Conclusion: cervical spine trauma remains a heavy socio-professional handicap. In rural areas, despite the lack of equipment and the difficulties of care, our results are satisfactory. However, it is necessary to insist on psychotherapy for these patients.

The aim of this study was to carry out a dynamic simulation of the energy and environmental performance of a built space system, with a view to assessing its energy and environmental class. The use of a simulation and modeling tool, supported by various methodological references, formed the basis of our approach. Adopting a systemic perspective, we described the structural and functional aspects of the systems making up built spaces, as well as the associated energy flows. Our approach was also based on a typology, taking into account typical days, structural and functional configurations at different scales and angles of observation. The analysis tool we developed in Java was applied to the built space system of the Patte d’Oie university campus in Ouagadougou. Annual electricity consumption was measured at 124387.34 kWh, closely aligned with the average annual electricity bill (125224.31 kWh), with a maximum relative deviation of 1%, followed by a carbon emission balance of 58337.66 kg eq CO2 per year. This validation confirmed the effectiveness of our tool. In addition, following the analysis of electricity consumption using our tool, the university campus was classified in energy class B and environmental class C. These results will be based on the emission factors of the energy mix of the West African Economic and Monetary Union (WAEMU) territory, with particular emphasis on Burkina Faso.

Living fishery resources, although rich and important for human populations, are subject to strong anthropization, thus causing a change in the environmental parameters of aquatic ecosystems. These multiple combined pressures: chemical, hydro-morphological, thermal or trophic, affect and disrupt the functioning of aquatic organisms. The objective of this study was to assess the main human pressures influencing the surface water resources of the Kamsar sub-prefecture, in order to propose mitigation measures. The following methodological approach was adopted: 1) Survey of managers and analysis records;2) Survey of stakeholders;3) Assessment of the effect of human activities on surface water resources;4) Data processing;5) Corrective measures. The survey farmers working near aquatic environments, revealed a low use of chemical substances, in particular 3 to 11 kg of fertilizer and 0 to 3 boxes of herbicide on fields of 40 m2 to 2 ha. Some physico-chemical parameters have been determined: Temperature (28.5˚C, 23.7˚C, 22.8˚C, 21.3˚C, 21.6˚C), Salinity (26.9‰, 21.9‰, 21.5‰, 15‰, 15.3‰) and Turbidity (21.3 UTN, 19.3 UTN, 17.8 UTN, 16.7 UTN, 17 UTN). These values show a fluctuation in the environmental parameters of aquatic ecosystems, which constitutes an obstacle to the development and survival of the resources.

Accessing drinking water is a global issue. This study aims to contribute to the assessment of groundwater quality in the municipality of Za-Kpota (southern Benin) using remote sensing and Machine Learning. The methodological approach used consisted in linking groundwater physico-chemical parameter data collected in the field and in the laboratory using AFNOR 1994 standardized methods to satellite data (Landsat) in order to sketch out a groundwater quality prediction model. The data was processed using QGis (Semi-Automatic Plugin: SCP) and Python (Jupyter Netebook: Prediction) softwares. The results of water analysis from the sampled wells and boreholes indicated that most of the water is acidic (pH varying between 5.59 and 7.83). The water was moderately mineralized, with conductivity values of less than 1500 μs/cm overall (59 µS/cm to 1344 µS/cm), with high concentrations of nitrates and phosphates in places. The dynamics of groundwater quality in the municipality of Za-Kpota between 2008 and 2022 are also marked by a regression in land use units (a regression in vegetation and marshland formation in favor of built-up areas, bare soil, crops and fallow land) revealed by the diachronic analysis of satellite images from 2008, 2013, 2018 and 2022. Surveys of local residents revealed the use of herbicides and pesticides in agricultural fields, which are the main drivers contributing to the groundwater quality deterioration observed in the study area. Field surveys revealed the use of herbicides and pesticides in agricultural fields, which are factors contributing to the deterioration in groundwater quality observed in the study area. The results of the groundwater quality prediction models (ANN, RF and LR) developed led to the conclusion that the model based on Artificial Neural Networks (ANN: R2 = 0.97 and RMSE = 0) is the best for groundwater quality changes modelling in the Za-Kpota municipality.

Introduction: Minimally invasive urological interventions have long been practiced blindly in our context. The popularization of ultrasound in urological practice has contributed to changing habits by making the procedures safer and more effective. The objective of this work was to study the technical aspects, indications and results of minimally invasive urological procedures guided by ultrasound. Material and methods: This was a prospective descriptive study lasting 1 year from January to December 2023 at the Médicis clinic in Conakry. Results: We carried out 126 ultrasound-guided urological interventions in one year, including 6 percutaneous nephrostomies (NPC), one renal cyst puncture-aspiration-sclerotherapy, 102 prostate biopsies, 5 drainages by transrectal aspiration of prostatic abscesses, 10 placements of cystostomy probes. Suprapubic, 2 puncture-aspiration-sclerotherapies for vaginal hydroceles. The average age of our patients was 69 years and the predominant age range was 61 - 70. The majority of our patients were male (97.61%) with a sex ratio of 41 men to one woman. Ultrasound-guided urological interventions were for diagnostic purposes (80.95%), for therapeutic purposes (15.77%) and for diagnostic and therapeutic purposes (3.96%). The indications for ultrasound-guided urological interventions were dominated by prostate pathologies (84.91%). The majority of interventions were performed rectally (84.92%) versus (13.43%) abdominally and only 1.58% scrotalally. All procedures were performed in B-ultrasound mode under local anesthesia and on an outpatient basis. For therapeutic interventions, the patients were seen again one month after the procedure, the clinical examination and ultrasound control found the evolution to be favorable. Conclusion: ultrasound is useful in urological practice for guiding minimally invasive interventions. The indications for ultrasound-guided procedures in urology are dominated by prostate pathologies. These procedures are safe

Background: Liver abscess (LA) is a suppurated collection in the hepatic parenchyma. In Africa, liver abscesses are most often of amoebic origin, but more recently, the rate of pyogenic liver abscesses (PLA) has increased. Objective: to assess the epidemiological characteristics, clinical features, biological radiological findings, and outcomes of patients with PLA and with amebic liver abscess (ALA) in order to determine the potential factors that may help improve diagnosis and treatment for LA in the context of secondary care centers with limited medical supports. Methods: Retrospective review of LA diagnosed and treated at three secondary care centers in Thiès over 11 years. Results: 61 patients, were included, 52.45% had ALA and 47.54% had PLA. Males were predominant (79.31% in PLA vs 65.63% in ALA, p = 0.2). The median age was 38 years for the PLA group vs 39 years for the ALA group (p = 0.4). In both groups, the most common symptom was right upper abdominal pain (81.97%), hepatomegaly (81.97%). The PLA group had a higher prevalence of fever (79.31% vs 46.88%, p = 0,009), chills (51.72% vs 18.75%, p = 0.007), right basi-thoracic pain (55.17% vs 28.13%, p = 0.032), and jaundice (55.17% vs 28%, p = 0.032). There was no difference in radiological features between PLA and ALA. Patients with PLA had a higher level of White blood cell (20.600 vs 15.400, p = 0.014). The most common bacteria identified in PLA were Escherichia coli (58.8%). All patients had received antibiotic therapy, which was combined with aspiration puncture (37.3%), transcutaneous drainage (43.3%), and surgery (9.0%). Seven patients had received antibiotic therapy alone and all had amoebic abscesses. Elsewhere, the occurrence of complications was higher in PLA cases (75.86% vs 37.5%, p = 0.003). The overall hospital mortality rate was 13.11%, higher in cases of PLA (24.14% vs 3.13%, p = 0.022). Conclusion: Clinical and biological features were more severe in PLA. But radiological features cannot be

Introduction: Ametropias or refractive errors are pathologies commonly encountered in ophthalmology characterized by the projection on the retina of a blurry image. There are several types of ametropia and each of them has a specific means of correction. In the literature, numerous data have been reported on the issue through studies that were mostly carried out on infant populations. To better treat ametropia in a more formal way, it is important to know their general characteristics within a larger population, hence the present investigation, the aim of which is to carry out an epidemiological study of ametropia at the Kati University Hospital-BSS. Materials and Methods: The study was carried out at Kati University Hospital-BSS between January 1 and December 31, 2022 and included 663 ametropic patients of all ages. Results: During the study period, 663 cases of ametropia were diagnosed out of 1678 new consultations, representing an incidence of 39.51%. Patients aged between 21 and 40 years were more affected. Depending on the type, these ametropias were dominated by compound astigmatism with 68.75% followed by isolated hyperopia and isolated astigmatism. Visual fatigue was the most mentioned reason for consultation. The female gender was in the majority with 70.9%. Low ametropia (Discussion: The growing visual needs of young people, especially with new information and communication technologies, would push them to consult the ophthalmologist more, and therefore to want optical correction in the event of a refractive anomaly, which would partly explain their high frequency in this age group. Conclusion: It is important to know the general characteristics of ametropia in the general population in order to improve the quality of life of patients affected by it through efficient therapeutic solutions.

Background: To reduce infant and child mortality in Benin, a package of high-impact interventions per healthcare level was implemented in 2009. This study aimed to assess the quality of community-based health interventions in reducing infant and child mortality within the municipality of Pobè in southeastern Benin. Methods: This was a cross-sectional evaluative study carried out in November 2021 focused on children aged 0 - 59 months, their mothers, health workers, community facilitators, community health workers and the Town Hall health focal point. Mothers and their children were targeted by cluster sampling, and exhaustive selection was used to recruit all other participants. Predetermined scores based on rating criteria were used to assess the quality of community health interventions using the “input, process and outcome” of Donabedian approach. Results: Over 300 mother-child couples, 46 community health workers, 7 health agents, 1 community facilitator and 1 health focal point from Pobè town hall were surveyed. Intervention quality was judged as “average”, with a score of 73.80%. The “inputs” and “outcomes” components were the weakest links. Conclusion: Improving access to the inputs needed by community health workers can enhance the quality of PIHI interventions.

This study describes the floristic composition and structure of a woody stand in the Senegalese Sahel, paying particular attention to the edaphic factors of its floristic composition. A stratified inventory considering the different relief units was adopted. Woody vegetation was surveyed using a dendrometric approach. The results obtained show that the flora is dominated by a few species adapted to drought, such as Balanites aegyptiaca (L.) Del., Calotropis procera Ait. and Boscia senegalensis (Pers.). The distribution of this flora and the structure of the ligneous plants are linked to the topography. In the lowlands, the flora is more diversified and the ligneous plants reach their optimum level of development compared with the higher relief areas. In the lowlands, there are a few woody species which, in the past, were indicative of better climatic conditions. These are Anogeissus leiocarpus (DC.), Commiphora africana (A. Rich.), Feretia apodanthera Del., Loeseneriella africana (A. Smith), Mitragyna inermis (Willd.) and Sclerocarya birrea (A. Rich). It is important that their reintroduction into reforestation projects takes account of their edaphic preference.
