The purpose of this study is to evaluate our results of treatment of post-traumatic bone defect of members through various bone reconstruction techniques. Patients and method: It is a retrospective study continues from January 2008 to December 2012. It involved 27 patients who had bone loss following trauma members. The average age of patients was 36.2 years. We noted a male predominance (22 men). The causes of injuries were dominated by accidents of public roads (12 cases) and ballistic trauma (14 cases). We noted one case of work accident. The BL was localized in 10 cases the tibia, femur in 4 cases, 8 cases in the humerus, 2 cases in the fibula, 1 case was located in the olecranon, 1 case at the distal radius and 1 case to the ball. All lesions were open fractures. After a mean of support for 3 days, we performed emergency around 19 associated with internal fixation (10 cases external fixation, internal fixation 9 cases), 8 single around. Bone reconstruction was performed secondarily in the majority of cases (24 cases). Only 4 reconstructions were performed in emergency. Reconstruction techniques were dominated by conventional grafts (24 cases) associated or not with the technique of induced membrane. Bone reconstruction techniques we used were as follows: 24 cases of traditional autografts and 3 cases of intertibio-fibular graft. After an average decline of 43.6 months, our patients were evaluated clinically (axis and limb length) and radiological (bone healing). Results: bone healing was achieved in 22 cases after a mean of 3.8 surgeries and an average of 14.8 months. Conclusion: the main principles governing the reconstruction of a defect are pre healing associated infection and repair soft tissue whenever it can do. The current trend is to hybridization of the reconstruction process of the great losses of substance by developing strategies based on both the deliberate shortening.

We report an unusual manifestation of nontuberculous mycobacterial infection characterized by a giant bursitis on wrist and multiple tenosynovitis with many rice bodies formations. The clinical and radiological examinations are neither rather sensitive nor rather specific. The nuclear imagery of rice bodies formations provides elements of guidance. Cause of absence of the germ isolation, diagnosis was retained on probability items based on a suspicion of arguments beam: clinical, biological, bacteriological and histological. The patient was treated with medical and surgical procedure and provided a satisfactory evolution. At follow-up of 15 months, there were no clinical signs of local recurrence. Through a literature review, the problem of diagnosis of certainty will be discussed.

Primary bones cancers are rare and ubiquitous malignant tumors. Aim: Our study aimed was to describe the epidemiological and histopathological aspects of primary malignant bone cancers in Ivory Coast. Material and method: This is a retrospective and descriptive study of primary malignant bone cancers diagnosed over the period 1990 to 2013 (24 years). The studied parameters were: epidemiological aspects (frequency, age, sex, topography) and histological aspects. Results: Over the study period, primary malignant bone cancers accounted for 1.93% (n = 228) of cancers. The average age was 27.02 years with extremes of 2 and 85 years. The sex ratio was 1.65. They were in the skull and maxilla in 43.9% (n = 105), lower limbs (23.8%), spine and ribs (19.8%), pelvis (5.3%) and upper limbs (2.3%). The clinic was dominated by pain and alteration of general state. Radiology was variable depending on the histological type. In children, primary malignant bone cancers were found in the maxillary (77.9%) and the lower limb (15.8%). Burkitt’s lymphomas represented 36.4% (n = 66) of the histological types followed by 22.4% osteosarcomas (n = 51). In adults at histology, sarcomas were the most common (10%), followed by cancers of the hematopoietic and lymphatic organs (8.09%). Conclusion: Primary malignant bone cancers are rare in Ivory Coast. They most often affect male children with maxillofacial involvement and predominant lower extremity. Burkitt’s lymphoma and osteosarcoma are the often diagnosed histological types.

Journal of Geoscience and Environment Protection 2024年第9期12卷 370-387页

作者： Emmanuel Aguiza Abaï Hugues Pahimi Prosper samba Koukouare Guillaume Ewodo Mboudou Auguste Ombolo Department of Industrial Security Quality and Environment National Advanced School of Mines and Petroleum Industries University of Maroua Kaele Cameroon School of Chemical Engineering and Mineral Industries University of Ngaoundere Ngaoundere Cameroon Department of Hydrocarbons Exploitation Mao National Higher Petroleum Institute NDjamena Chad Department of Hydraulics and Water Management National Advanced School of Engineering of Maroua University of Maroua Maroua Cameroon Department of Rural Engineering Higher Institute of Agriculture Forestry Water and Environment University of Ebolowa Ebolowa Cameroon

The use of groundwater for drinking water supply to the population is increasingly practiced in the rice cultivation area of Maga. However, there is a lack of knowledge about the hydrochemical characteristics of this water due to a lack of quality control. This study aims to contribute to the understanding of mineralization processes in order to establish the hydrochemical profile of the water in the area. The methodological approach consisted of collecting fifteen water samples from wells and boreholes during six campaigns for physicochemical analysis, and studying them through methods of interpreting hydrochemical data. The analysis results show that these waters are moderately mineralized. The water facies are mainly of the bicarbonate sodium and potassium type, as well as the bicarbonate calcium and magnesium type. Calculation of saturation indices demonstrates that evaporite minerals show lower degrees of saturation than carbonate minerals, with gypsum, anhydrite, and halite being in a highly undersaturated state. The mineralization of groundwater originates from the dissolution of surrounding rocks on the one hand, and anthropogenic activities involving exchanges between alkalis (Na+ and K+) in the aquifer and alkaline earth (Ca2+ and Mg2+), resulting in the fixation of alkaline earth and the dissolution of alkalis.

Physicochemical investigations were performed on seeds of Nymphea lotus and N. micrantha consumed in the Senegal River valley. They revealed a composition similar to that of cereals. In order to estimate their intrinsic quality, the determination of their amino acid, fatty acid and monosaccharids profiles was done. The results indicate that monosaccharides are represented specifically by saccharose (7%) and glucose (0.67%);a predominance of stearic acid and linoleic acid as unsaturated acids (24.86%);arachidic and palmitic acids as the only saturated acid found (11.12%);a good ratio of unsaturated/saturated acid (2.23);a lack of oleic acid, linoleic, palmitoleic, myristic, caprylic acids;a poor-quality index protein due to low quantity amino acids. Nevertheless, all essential amino acids are present in the seeds. The Nymphea sp grains consumed by the populations around the Senegal River valley offer an interesting nutritional quality linked to fatty acids and carbohydrates.

Ceramic Properties of Three Specimens of Alluvial Clays Used in Local Constructions from Mbouda Clay Deposit, West Cameroon

引用

Journal of Minerals and Materials Characterization and Engineering 2024年第5期12卷 265-279页

作者： Philémon Zo’o Zame Sylvain Kouayep Lawou Philippe samba Assomo Audrey Erman Moutsou Yannick Lontchi Dzoti Véronique Kamgang Kabeyene Beyala Faculty of Science University of Yaound I Yaound Cameroon Higher Teacher Training College Bertoua University of Bertoua Bertoua Cameroon Faculty of Science University of Dschang Dschang Cameroon

The Mbouda alluvial deposit is located at the foot of the Bamboutos mountains (West Cameroon) where three types of clayey materials are widespread. The populations collect these clays in their natural state in view of constructions using fired bricks or compressed blocks. Unfortunately, these buildings are not strong. This study investigates the causes of the strengthlessness of buildings and suggests solutions to overcome the difficulty. The research content includes field and laboratory studies. The methodology consists of sampling black (AN), white (AB) and red (AR) clays specimens identified in the study area and analysing them simultaneously at MIPROMALO (Cameroon) and at ACME LAB in Vancouver (Canada). The results obtained show a high sand content in the samples AN (64%), AB (55.2%), AR (30.9%). The compressive strength of the built specimens is low at 900˚C considered as the traditional firing temperature AN (0.94 MPa), AB (5.25 MPa), AR (2.18 MPa). The mineralogical series are identically made by kaolinite, chlorite, gibbsite, quartz, muscovite, biotite, goethite, magnetite and hematite. Silica (SiO2) presents higher contents AN (52.87%), AB (48.02%), AR (47.68%) followed by alumina (Al2O3) AN (29.96%), AB (28.13%), AR (24.72%). The other elements are poorly represented.

Introduction: Infections are additional factors of morbidity and mortality in multiple myeloma (MM), and the current recommendation is antibiotic prophylaxis. In sub-Saharan Africa, few data on infectious complications of MM are available. We aim to describe the microbiological features of infections in MM, and their impact on survival in Senegalese patients. Methods: A retrospective (January 2005-January 2022), analytic, multicenter study on infections in patients followed for MM (IMWG criteria) in Senegalese clinical hematology services. The socio-epidemiological, diagnostic, microbiological, evolutionary and survival aspects were analyzed. Results: The study included 106 patients with multiple myeloma who had an infection at admission or during the treatment. Ten patients have the comorbidity (hypertension, lupus, type 2 diabetes). These patients had 136 infectious events identified at diagnosis (79.2%) or during chemotherapy (20.8%). The sites of infection are lung (42.6%), urinary (29.4%), dermatological (6.6%), digestive (5.2%), osteoarticular (4.4%), ear, nose and throat (3.7%), central nervous system (1.5%), or without site. We recorded 26.4% of patients with multi-site infections. The causal pathogens are bacteria (Gram-negative bacilli: 22.1%;Gram positive bacilli: 9.5%, Mycobacterium tuberculosis: 13.3%), parasitique (plasmodium falciparum 6.6%), viruses (SARS-COV2: 2.9%, VZV: 2.2%) and fungal (2.9%). Survival was reduced in patients who had an infection at the time of multiple myeloma diagnosis (p: 0.189) and those who had multiple infectious foci (p: 0.011). Conclusion: Infections in multiple myeloma are more frequent at diagnosis. The germs are varied and mostly bacteria, particularly gram-negative bacteria, and Kochs bacillus. Our study reveals that multiple infectious foci are a poor prognosis factor. It is necessary to evaluate the infectious risk early, and to adopt an antibiotic prophylaxis based on our tropical environment.

Introduction: Heart failure is a major public health pandemic, particularly in Africa, where its prevalence continues to increase. In northern Mali, few data exist, hence the interest of this study with the objective of studying the epidemiological, clinical and therapeutic and evolutionary aspects of Heart failure at the regional hospital of Gao. Patients and Methods: This was a cross-sectional, descriptive study that took place from July 2022 to June 2023 in the medical department at Gao Hospital. Results: The hospital prevalence of heart failure was 44.1%. The mean age was 47.30 ± 20 years (range: 16-88). Hypertension was the most common with 46.1%, followed by a sedentary lifestyle, and diabetes with 18.2% and 8.3% respectively;NYHA stage III-IV dyspnea was found in 83.9%. Reduced EF heart failure was present in 110 patients (76.9%), seventeen cases with moderately reduced EF (11.9%) and sixteen patients had preserved EF (11.2%). Global heart failure was the dominant (91.6%). The main etiologies of heart failure were dominated by hypertensive heart disease in 46 patients (32.2%), followed by postpartum cardiomyopathy with 43 cases (30.1%), primary dilated cardiomyopathy in 18 patients (12.6%), ischemic heart disease in 16 patients with 11.2%. Seven cases of valvular heart disease, or 4.9%. The evolution was favorable under treatment in 104 patients or 72.7%. In-hospital mortality was 14.7%. Conclusion: Heart failure is a common condition in sub-Saharan Africa, particularly in our country.
