Objective: The work aimed at describing an epidemioclinical, therapeutic and evolutionary characteristics of patients hospitalized for aortic dissection in the cardiology department in Point “G” Hospital University Center in Bamako—Mali. Methodology: It was a descriptive cross-sectional study from January 2010 to February 2017 in the CHU Point G cardiology department, including all patients hospitalized during this period. Results: Of 6912 hospitalized patients, 23 patients were concerned by aortic dissection. The prevalence of aortic dissection was 0.33%. The most affected age group was 50 - 69 (43.5%) of patients. The predominance was male with a sex ratio of 4.75. The cardiovascular risk factors were high blood pressure (73.9%) and smoking (60.9%). The major functional signs were chest pain (65.2%) and dyspnea (65.2%). Asphygmy (56.5%) and breath of aortic insufficiency (60.9%) were the dominant physical signs. The electrocardiogram recorded sinus tachycardia with 86.9% of patients. The radiographic of the frontal thorax showed mediastina widening (73.9%). At echocardiography, dilatation of the ascending aorta was described with 73.9% and the intimal veil (47.8%). Pericardial effusion was observed with 26.1% of patients. In the thoracic angioscan, the aortic dissection gave 43.5% for type A and 56.5% for type B. The aneurysm of the aorta was abdominal with 21.7%, ascending portion (13.0%) and descending with 8.7%. Complications were dominated by heart failure (47.8%) and aneurysm of the aorta (34.8%). The lethality was 52.2%. Conclusion: Aortic dissection is a medical and surgical emergency with poor prediction.

Context and Objective: Groin hernia is a common pathology in visceral surgery (2nd rank after appendicitis), which affects approximately 4.6% of the African population. Restoring the normal anatomy of the groin region is one of the most benign interventions. However, uro-andrological complications are possible. This study aimed to contribute to the improvement of the management of urogenital complications of groin hernia surgery. Patients and Method: We carried out a prospective study of descriptive type with a duration of 6 months from 1 August 2021 to 31 January 2022. The data were collected using a pre-established survey sheet. The study covered several sites (public hospitals and private clinics) in Guinea. Results: The urogenital complications of the surgery of the hernia of the groin represented 15.22% or 14 cases out of 92 patients. The average age was 37.00 years with extremes of 20-69 years. Polygamists occupied the first place. The reason for consultation was dominated by decreased testicular volume (42.86%), followed by a desire to conceive (21.43%). Unilateral testicular atrophy represented 63.64%, bilateral 27.27%. We performed a left orchidectomy in one patient and a cystorraphy in another simple operative follow-up. The other cases consisting of testicular atrophy, due to lack of a suitable technical platform, did not benefit from any specific therapeutic treatment. Conclusion: Urogenital complications of groin hernia surgery are relatively common. Testicular atrophy was the main clinical complication. The left orchidectomy and cystorraphy were the therapeutic procedures performed.

Intraorbital Mature Teratoma in Infant

引用

Open Journal of Modern Neurosurgery 2022年第3期12卷 127-131页

作者： oumar Diallo Abdoulaye Hima Maiga Bekety Katanga Anthony Mahamadou Dama oumar Coulibaly daouda Sissoko Alpha Singuepiré Hospital of Mali Bamako Mali Hospital of Niamey Nyamay Niger Hospital of Kara Kara Togo Hospital of Ségou Ségou Mali

Intraorbital mature teratoma is a rare congenital tumor of slow evolution that can compromise vision. Objectives: We describe the clinical and therapeutic aspects of a mature teratoma in childhood with a literature review. Clinical Case: It was a 12-year-old who had a progressive straight monocular exophthalmia with blindness. CT without and with contrast injection showed a double component intracolonic invasive tumor with partial contrast acquisition after injection. This tumor respected the bone walls of the orbit. The treatment was surgical by conjunctival dissection of the tumor and enucleation. This allowed the tumor to be fully excised under an operating microscope. The operating procedures were simple. Anatomopathology confirmed the nature of the tumor by visualizing the presence of a squamous epithelium by the high-magnification (X20) method of hematoxylin and eosin. Conclusion: Mature intraorbital teratoma is an embryonic tumor with early diagnosis the finding in an older child remains rare. Complete surgical excision allows healing.

Introduction: Gold panning is the research and artisanal exploitation of gold in the auriferous areas (rivers or others). Traumatisms arising from these activities are due to severe spinal cord injury and generally affect young people in full activity. They constitute a real social handicap in Mali and even in Africa. The aim of our study is to share our expertise in the management of these vertebro-medullary traumasin these miners who currently escape to all controls in Mali. Material and Methods: From 2013 to 2016, 76 Traumatic Spine Cord Injuries (TSCI) were treated in the department of Neurosurgery of “Hôpital du Mali”. There were 73 males (96.05%) versus 03 Females (3.95%), aged between 21 - 43 years old. Results: All of our patients were admitted with deficit differing from paraparesis to tetraplegia. According to Frankel scale, we found 59 patients with complete deficits (A grade, 77.63%), and incomplete deficits in 17 cases (12 grade B, 04 grade C, 01 grade D). The X-ray standard radiographies were done in 24 cases (31.58%) from which 02 patients had been operated with these data. CT scan centered on the injured spinal segment was performed in 74 cases (97.37%). The lumbar spine was affected in 39 cases, followed by thoracolumbar junction in 19 cases and thoracic spine in 16 cases. The cervical spine was only interested in two cases. Fractures dislocations are the most frequently lesions encountered in our series. The surgical approach was performed in 74 patients and 02 patients received conservative treatment. Conclusion: Traumatic Spinal Cord Injuries (TSCI) among miners are a real disaster in Mali and continue to plague thousands of families or increase the number of disabled people in our society. It is the only work, where the person concerned is making of his own grave. And according to witnesses, several miners remained at the bottom of the wells. Their prevention must first involve users by raising the awareness of local residents and traditio

Management of the Water Slide Brought and Saline Flow in Irrigated Onion (<i>Allium cepa</i>L.) Cultivation in the Senegal River Delta

引用

Agricultural Sciences 2021年第11期12卷 1255-1268页

作者： Eric Kaly oumar Sarr Raymond Malou Sékouna Diatta daouda Ngom Aliou Guisse Laboratory of Plant Ecology and Eco-Hydrology Department of Plant Biology Cheikh Anta Diop University Fann Dakar Senegal Hydrogeology Laboratory Department of Geology Cheikh Anta Diop University Fann Dakar Senegal

The find for the optimal slide of water to bring to the plot during the irrigated onion crop was important in order to limit the recharge of the water table close to the soil surface. The quantities of water supplied during onion irrigation were estimated from measurements made with a metal crest to the plot positioned at the tertiary canal. The flow rates at the tertiary canal directly irrigating the plot were recorded during irrigation. From this flow rate, the quantity of water supplied to each plot was determined. From then, the performance of the irrigated system in onion cultivation should pass on the management of this water slide at the level of the hydroagricultural facilities. The integrated soil water mass, salinity and water table dynamics monitoring system was used to assess the water requirements of onion following the irrigation. The daily water requirement of onion in the holland soil of the delta was estimated to average 0.45 g/m3. These requirements were varied according to the development stage of the crop. The water level between the ridges was between 6 and 9 mm during irrigation. This was not permanent, it infiltrated between 12 and 18 hours. This type to the stingray irrigation did not favour the arrival of the water table on the surface. The only fluctuations in the water table were observed during the bulb maturation phase. During this phase, the soil water masses were important. The electrical conductivity recorded varied during the campaign. At the beginning of irrigation, it was 3.62 mS/cm on a 30 cm profile, it decreased towards the end of the irrigations to reach 2.06 mS/cm. The quantities of salt recorded on a 30 cm profile varied from one month to the next;they were 0.468 t/ha at the beginning of irrigation (January) and 0.275 t/ha at the end of the campaign (April). From these results we can say that land degradation in the Senegal river delta would be linked to the arrival of salty groundwater on the surface.

Angiographic Features of Intracranial Aneurisms in Mali: A Preliminary Study of 105 Patients

引用

World Journal of Neuroscience 2023年第1期13卷 1-11页

作者： Mahamadou Dama oumar Coulibaly oumar Diallo daouda Sissoko Hawa Diarra Kalba Tembine Mamadou Salia Diarra Madani Ouologem Drissa Kanikomo Neurosurgery Department University Hospital of Mali Bamako Mali Radiology Department University Hospital of Mali Bamako Mali Anesthesiology Department University Hospital of Mali Bamako Mali Neurosurgery Department Hospital of Luxembourg Bamako Mali Unite of Neurology Infirmery of the Armies Bamako Mali Department of Neurosurgery Gabriel Touré Hospital Bamako Mali

Introduction: Rupture of intracranial aneurisms leads to severe morbidity and mortality. There are two modalities of treatment surgery and endovascular treatment. The diagnosis is made by angiography (DSA, CTA, RMA). The angiographic features used to assess the risk of the complications and choose the treatment modality are size, location and aneurism morphology. Materials and Methods: We reviewed and analyzed the computed tomographic angiography and magnetic resonance angiography of all patients admitted to the hospital of Mali with IAs from 2015 to 2021 either 7 years. Patients who were less than 18 years old, those with non-aneurysmal SAH, patients who request a discharge and those with an incomplete angiographic description of the IAs were excluded from the analysis. Results: We have collected 105 patients with 109 aneurysms. The sex ratio was 2/1 in favor of females. The mean age was 44.51 years with the range from 18 to 70 years. The presentation mode was subarachnoid hemorrhage (SAH) in 97% of cases. 76.19% had confirmed high blood pressure before the bleeding. 19.04% were diabetics. 98% of our patients have made a CT angiography and 2% have made MR angiography for the aneurysm diagnosis. 97.24% of aneurisms were located in the anterior part of the Willis circle. 39.44% of these aneurisms were the anterior communicating complex aneurysm. 27.52% of aneurysm had a small size, 42.20% had a medium size, 20.18% large size against 5.50% of the giant (Figure 3) and the middle cerebral artery was the most involved in the least. 95.41% of cases were saccular aneurysms against 4.59% fusiform. Conclusion: The angiographic feature of an intracranial aneurism in the Malian population may differ from other populations of the sub-region. The anterior communicating complex aneurysm is more common and the aneurism of the posterior part of the Willis circle is less common. We found the aneurism size ≥ 6 mm, ACA, MCA and Pcom more frequent.

Characterization and Risk Assessment of the Collapse of the Woody Stand of Ecosystems of the Fathala Forest (Saloum Delta Biosphere Reserve-Senegal)

引用

American Journal of Plant Sciences 2021年第7期12卷 975-993页

作者： Eric Kaly oumar Sarr Sékouna Diatta Abdoul Aziz Diouf Djibril Diouck daouda Ngom Laboratory of Plant Ecology and Eco-hydrology Department of Plant Biology Cheikh Anta Diop University Dakar Senegal Ecological Monitoring Center for The Management of Natural Resources (CSE) Fann Residence Dakar Senegal National Parks Directorate Ministry of Environment and Sustainable Development Dakar Senegal

The objective of this study is to characterize and assess the risk of collapse of woody plant formations in the Fathala forest. In recent years, this forest has suffered a sharp reduction in its plant cover to the point of compromising the survival of populations of certain animal species such as the Red colobuses. The methods used are respectively constituted by the transect method, the dendrometric statements method and that of establishing the red list of ecosystems of the IUCN. The specific richness comprises 56 species divided into 47 genera and 22 families. The density is higher in the unfenced area (369 ind/ha in clear forest and 53 ind/ha in gallery forest) compared to the fenced area (160 ind/ha in clear forest versus 48 ind/ha in gallery forest). A study of the plant formations shows a strong degradation of the ecosystems passing from a clear and dry Sudanese forest to a wooded savannah. The cover rate in the fenced area is 20% in gallery forests and 25% in clear forests;in the unfenced area, it is 19% and 23% in gallery forests and clear forests, respectively. The application of the IUCN criteria shows an annual rate of collapse is -6 ind/ha in gallery forests and -4 ind/ha in clear forests. The annual rate of cover collapse would be -3.75% and -2.9% for gallery forests and clear forests, respectively. These results classify the forest in the Critically Endangered category. The main factors responsible for this degradation are, among others, anthropogenic actions and climatic pejoration. These results could constitute a basic tool for undertaking an improvement in the management of this forest, which is a living environment for an animal species.

The Hepatic sinusoidal obstruction syndrome (HSOS), also known as veno-occlusive disease (VOD), is a well-known complication of haematopoietic stem cell transplantation, of the treatment of Wilms tumor and rhabdomyosarcoma and maintenance therapy of acute lymphoblastic leukemias. Its occurrence is rare in other cancers of the child. We report the observation of a 7-year-old girl with Burkitt’s lymphoma who developed a severe HSOS during her second induction treatment with dexamethasone, cisplatin, cytosine arabinoside. The evolution was fatal. This observation shows that the diagnosis of HSOS should not be excluded in the absence of the risk factors usually described.

Valorisation of Auriferous Indices: Case of the Siribaya Deposit, Western Mali

引用

Open Journal of Geology 2021年第10期11卷 457-470页

作者： Fodé Tounkara Jianguo Chen Mory Sidibe oumar Soumare Adama Youssouf koné Université de Ségou Ségou Mali State Key Laboratory of Geological Processes and Mineral Resources China University of Geosciences Wuhan China Ecole Nationale d’Ingènieurs Abderhamane Baba Touré Bamako Mali Laboratoire de Cartographie Département de Géologie Faculté des Sciences et Techniques (FST) Université des Sciences des Techniques et des Technologiques de Bamako (USTTB) Bamako Mali

The purpose of this paper is to understand the valorization of gold showings in the Seribaya deposit, western Mali. Samples taken from Air Core (AC) boreholes were subjected respectively to the magnetic susceptibility test and the X-ray fluorescence analysis. These results lead to the development of a simple methodology, based on signatures/indicators geochemical to identify lithology or to locate mineralization. We note that, compared to other chemical elements, Arsenic remains the most correlated with gold in the study area. Since this correlation remains weak (r = 0.16), it shows that Arsenic does not always accompany gold. There would be a generation of Arsenic related to mineralization, and other generations that would not be. The observation of the strip logs led to the identification of the lithologies (focusing on the immobile elements, Ti, V, Cr, Y, Zr) and the establishment of the alteration profile. Highly altered levels (Saprolite ± Saprock) are characterized by the disappearance of most mobile elements. A medium to strong correlation between gold mineralization and magnetic susceptibility measurements has been observed, in some places, and at depths. These mineralized intervals typically consist of quartz veins, suggesting that they have structural control over the mineralization. Gold mineralization is believed to be related to quartz veins. In addition, gold would be in paragenesis with a generation of Arsenic hosted in coarse sediments.
