Introduction: Bladder tumors are common in our country;Mali is a bilharzial endemic country. In our context, urinary bilharzia is common, and bladder tumors arouse particular interest in the field of urological oncology, because of their frequency, their diagnosis, their difficulty in management and their histological particularity. The objective of our work was to study the epidemiological, clinical and therapeutic aspects of bladder tumors. Materials and Methods: This is a cross-sectional, descriptive study with a retrospective and prospective collection that took place over 3 years from January 1, 2020 to December 31, 2022. Results: We identified 316 cases of bladder tumors during this period. Bladder tumors are a common pathology representing 35.95% of all hospitalized patients, and occupying the 1st rank of tumors in urology in the Urology Department of the Pr Bocar Sidy Sall University Hospital in Kati. Bladder tumors were more common in men with 56.33%. The average age of our patients was 50 years ± 25.8 years and the extreme ages were 20 and 87 years. Urinary schistosomiasis, considered a predisposing factor, was found in 66.78% of cases in our patients as a history. Transurethral resection of the bladder was performed in 100% of our patients, nephrostomy in 1.90% of cases, ureterostomy in 1.58% of cases, Bricker type urinary diversion in 1.27% of cases, and a neobladder in 0.32% of cases. Squamous cell carcinoma is the dominant histological type (88.29%). The postoperative outcome was 99% favorable after resection. Conclusion: Bladder tumors were mainly tumors infiltrating the bladder muscle. The main risk factor was urinary bilharzia. Squamous cell carcinoma is the most common histological type with a diagnostic delay, thus limiting radical treatment after resection of the bladder tumor.

Introduction: Ureteroscopy is a minimally invasive endoscopic surgery which provides access to the ureter, pyelon and calyceal cavities via the urethra and the bladder. Laser ureteroscopy uses the laser as an energy source to treat the stone and eliminate it naturally. Minimally invasive endoscopic methods are struggling to become popular in sub-Saharan African countries, especially for the upper urinary tract. The objective of our work was to report the results of our first laser ureteroscopy experience in the department. Materials and Methods: This was a prospective and descriptive study running from December 1, 2023 to February 19, 2024. Included in our study was any case of upper urinary tract stone operated by Laser ureteroscopy. The characteristics of the lithiasis were determined by CT scan. Sterilization of urine was verified by carrying out a cytobacteriological examination of urine. Ureteral lithiasis was approached by semi-rigid ureteroscopy. Renal lithiasis was immediately addressed by flexible ureteroscopy. Ureteroscopy was coupled with a Holmium YAG laser. A double J ureteral catheter was placed after the operation. A 230 µm laser fiber was used in each case with a generator with a power of 35 watts (Storz Calculase III type). An access sheath was used in all cases of flexible ureteroscopy. The parameters studied were: sociodemographic characteristics, lithiasis (site, size, number, density, topography), type of anesthesia, duration of laser use, duration of intervention, postoperative outcomes. Data entry and analysis were carried out using the software (Word 2016 and SPSS). Result: We collected 30 cases of laser ureteroscopy. The average age was 37 years with extremes of 9 and 79 years. The male gender was more represented. The most common age group was 24-39 years old. Renal colic was the most frequent reason for admission, 12 patients (40%). On physical examination, lumbar tenderness was present in 47% (14 patients). ECBU was positive in 4 patients

Journal of Computer and Communications 2024年第1期12卷 208-245页

作者： Bayomock Linwa André Claude traore Hamidou Department of Computer Science International University of Grand-Bassam Grand-Bassam Ivory Coast

Land acquisition is subject of many frauds worldwide. In Africa countries, land acquisition frauds are a real curse. Main reasons of the high land acquisition frauds in Africa are a lack of a reliable land acquisition protocol implementation, no centralized information system that records land transactions and integrates all actors, lack of education about the acquisition protocol and lack of applied sanctions in case of frauds. As of sanctions, the issue is bound to the corruption plague in Africa. Authorities that are supposed to rule the laws are not well paid and are part of the corruption scheme. Most frequent frauds are multiple sales of the same land, falsified land title, false owner identification. In Africa, a land belongs generally to the first residents of the area. To claim ownership of a land, an owner should be recognized by the rural or city authorities. To achieve this recognition, he must obtain from those authorities an attribution letter. The author proposed a complete and reliable land acquisition protocol named ACLAP (Africa Countries Land Acquisition Protocol). The purpose of this paper is to explain the main components of the protocol implementation and show its efficiency when confronting fraud threats. In this paper, a Generic and Reliable Land Acquisition Protocol Implementation in Sub-Saharan Africa countries context is proposed. The platform keeps relevant land transaction information for administrators, managers, buyers, sellers, or for people consultation purpose. The application may be used in village, city, department, region, or country for land management decision making.

Introduction: Pesticides are currently an essential component of agricultural production techniques for controlling pests and weeds. In Burkina Faso, non-compliance with good practice in the use of pesticides poses a real health problem for the population. This study examines the health risks associated with pesticide management in rice-growing areas. Material and Methods: A field survey was conducted in Bama, involving farmers, focusing on their socio-demographic characteristics, pesticide usage, and health effects. Cholinesterase levels were measured in subsample of farmers using a portable device. Data were analysed using Microsoft Excel, calculating means and percentages for various practices. Health consultations, protection methods, and pesticide management were studied. Erythrocyte acetylcholinesterase activity was compared before and after treatment. Data were categorised into classes based on inhibition levels, and correlation analyses determined relationships between variables such as age, years of experience, and cholinesterase activity. Results: The results indicate that rice cultivation is mainly carried out by a fairly young population, with nearly 63% being under the age of 50. Common poor practices in pesticide use include improper storage and reuse of leftover pesticides. Seven types of pesticides were identified, including organophosphates such as glyphosate, which was used in 26.7% of cases. This organophosphate has resulted in class B poisoning, causing a 30% - 50% reduction in erythrocyte cholinesterase activity. The health effects of pesticide use are felt by agricultural farmers through various symptoms of poisoning. Conclusion: To reduce the occurrence of pesticide poisoning, it is essential to launch information and awareness campaigns among the population and farmers to promote safe practices in pesticide use in Bama, Burkina Faso.

Understanding metal accumulation at organ level in roots, leaves and seeds in O. glaberrima (OG) is crucial for improving physiological and metabolic aspects in growing Asian and African rice in salted areas. The micro-analytical imaging techniques are required to reveal its accumulation and distribution within plant tissues. PIXE studies have been performed to determine different elements in rice plants. The existing microbeam analytical technique at the iThemba LABS will be applied for the 2D image mapping of fresh rice tissues to perform a concentration of low atomic mass elements (such as Al, Si, P, S, Cl, Ca, Ti, Mn, Fe, Cu, Br, Zn and K) with detection limits of typically 1-10 μg/g. Comparison of the distribution of the elements between leaves, root and seed samples using uptake and distribution of elements in particular environmental conditions with potential amount of salt in water have been performed. We are also expecting to indicate metal exclusion as salt tolerance strategies from leaves, root, and seed compartments using matrix correlation between samples and between elements on rice species.

Effect of Planting Date on Yield and Yield Components of Grain Sorghum Hybrids

引用

American Journal of Plant Sciences 2024年第5期15卷 387-402页

作者： Bandiougou Diawara Sory Diallo Brahima traore Scott Staggenbord Vara Prasad Institut D’ Economie Rurale (IER) Bamako Mali Manhattan KS USA

In Kansas, productivity of grain sorghum [Sorghum bicolor (L.) Moench] is affected by weather conditions at planting and during pollination. Planting date management and selection of hybrid maturity group can help to avoid severe environmental stresses during these sensitive stages. The hypothesis of the study was that late May planting improves grain sorghum yield and yield components compared with late June planting. The objectives of this research were to investigate the influence of planting dates yield and yield components of different grain sorghum hybrids, and to determine the optimal planting date and hybrid combination for maximum biomass and grains production. Three sorghum hybrids (early, medium, and late maturing) were planted in late May and late June without irrigation in Kansas at Manhattan/Ashland Bottom Research Station, and Hutchinson in 2010;and at Manhattan/North Farm and Hutchinson in 2011. Data on dry matter production, yield and yield components were collected. Grain yield and yield components were influenced by planting date depending on environmental conditions. At Manhattan (2010), greater grain yield, number of heads per plant, were obtained with late-June planting compared with late May planting, while at Hutchinson (2010) greater yield was obtained with late May planting for all hybrids. The yield component most affected at Hutchinson was the number of kernels∙panicle−1 and plant density. Late-May planting was favorable for late maturing hybrid (P84G62) in all locations. However, the yield of early maturing hybrid (DKS 28-05) and medium maturing hybrid (DKS 37-07) was less affected by delayed planting. The effects of planting dates on yield and yield components of grain sorghum hybrids were found to be variable among hybrid maturity groups and locations.

Despite its low resistance to humidity, adobe remains the most widely used material for housing construction, particularly in developing countries. The present study aims to assess different modes of use of fermented RH and to evaluate their influence on the behavior of raw earth for application in plaster. The influences of two types of RH are evaluated: granular rice husk (RHg) and powdered RH (RHp). The clay mainly consists of clay (40%), silt (22%), and sand (38.4%), with a small proportion of gravel (0.24%). Its liquidity limit is 40% and the plasticity index is 26.5%. The mixtures were designed using earth and each of the two rice husks at the volumetric content of 10%, 15% and 20% of the total volume mixed with water 36.5%, 38.5% and 40.3% and fermented for three weeks. Each fermented mixture was added to the soil to form the paste, and 40 × 40 × 160 mm3 test speciments were made for characterization. The results generally show an improvement in the physico-mechanical properties and water resistance of the mortars containing fermented RH, with an optimal content between 10% and 15%. The powdered RH improved the performance of the mortar better than granular RH.

Vaginal Cesarean Section, an Alternative to High-Risk Trigger on Scarred Uterus

引用

Open Journal of Obstetrics and Gynecology 2024年第7期14卷 979-982页

作者： Famakan Kane Mahamadou Keita Yacouba Sylla Soumaila Diallo Diassana Mahamadou traore Tidiane Hpital du District de Bla Bamako Mali Hpital du District Commune I Bamako Mali Hpital FOUSSEYNI DAOU de Kayes Bamako Mali Hpital NIANAKORO FOMBA de SEGOU Bamako Mali

The objective is to report a clinical case of vaginal cesarean section performed to expel a dead fetus in scarred uterus. For this indication, vaginal hysterectomy constitutes an alternative to vaginal expulsion with a high risk of uterine rupture and to classic abdominal cesarean section with risk of significant surgical trauma, particularly adhesions. However, this surgical technique, described since the 19th century, remains unknown to many practitioners and few publications exist on the subject throughout the world. Considered obsolete by some practitioners, it retains all its advantages in the practice of modern obstetrics. We report this case of expulsion of fetal death on a tri-scarred uterus performed by vaginal cesarean section at the Health District Reference Health Center (District Hospital) of Commune I in Bamako, Mali in a 37-year-old patient with a pregnancy of 27 weeks of amenorrhea.
