Chronic hepatitis B causes a liver disease characterized by inflammation of the liver parenchyma. The aim of this study was to investigate the evolution of biological parameters in patients treated with Tenofovir for chronic B infection at the Commune V referral health center in Bamako. We obtained a prevalence of 14.15%. The most represented age group was 31 - 40 years, with 36.8%. The sex ratio was 1.44 in favour of men. Viral load was undetectable after 18 months of treatment in 25 patients (42.37%). Tenofovir, the 1st-line drug in Mali, is effective on the biological parameters monitored in patients.

Infection with the defective hepatitis D virus (HDV) co-infects or superinfects a patient carrying hepatitis B virus (HBV). Delta virus infection is relatively common. The seriousness of infection with the hepatitis D virus (HDV), a virus defective in a patient carrying the hepatitis B virus (HBV), lies in its aggravating effect on the associated viral hepatitis B. Our aim was to study the serological profile of HDV in HBsAg-positive patients. As this study was fragmentary, we initiated this study with the aim of investigating the serological profile of HDV in HBsAg-positive patients. This was a descriptive and analytical cross-sectional study that ran from March 2019 to February 2020, a 12-month period. It focused on the population of patients seen and screened positive for HBsAg. We obtained a frequency of 10%. The mean age of our patients was 41.8 ± 13.09 years. The sex ratio was 4.5. VHD RNA was detected in 50% of patients. In 100% of cases, the presence of VHD RNA was associated with advanced fibrosis according to the APRI score, but without any statistically significant link. All HBV-infected patients should be screened for anti-HDV Ac. HDV infection leads to rapid progression to complications of liver disease.

Appendicitis bilharzia is a very rare condition and we report 3 cases of this pathology that sense clinical and biological similarities with bacterial appendicitis. The etiological diagnosis was exclusively histopathological, this allowed to highlight eggs of Schistosome in the appendicular wall in the three patients. The surgical treatment was supplemented by a specific medical treatment based on praziquantel. The surgical suites were simple for 2 patients, complicated by superficial parietal suppuration in a patient.

Cenchrus biflorus called Karangiya in the Hausa language is an annual pastoral grass which is a valuable herbaceous fodder in dry land region in the context of climate change. However, little is known about the plant water use under the effects of cut in West Africa Sahel like Niger where the plant is a multipurpose grass species. Therefore, this study investigated the impact of grazing (simulated by shoot cuts) on biomass production. Cenchrus biflorus Roxb was grown on field plots and in pots and subjected to shoot cuts at different levels (3 cm and 5 cm from soil surface). The effect of shoot cuts on drought tolerance was evaluated by assessing the response of transpiration to the diurnal variation of vapor pressure deficit (VPD). Results showed that the biomass production varied in response to shoot cuts depending on the culture system, and the level or frequency of cuts. The mean biomass production increased significantly especially in field plots for 5 cm cuts compared to those at 3 cm and the control treatment. In addition, transpiration was highly increased in response to the VPD increase. Shoot cuts significantly reduced transpiration, whatever the level, largely because they reduced leaf surface. We concluded that moderate grazing (cuts to 5cm) can improve biomass production and allow better adaptation to water deficit as they significantly reduced water loss through transpiration. The study recommends the cropping of the Cenchrus biflorus as climate solution as it performs better under water deficit for improving grazing resilience in Niger.

Introduction: The level of knowledge and attitude of health professionals about breast cancer are important determinants. General objective: To study the knowledge, attitude and practice of health professionals of the hospital of the district of the commune IV on breast cancer. Methodology: This was a cross-sectional, prospective, descriptive, qualitative and quantitative study. The study period was from 01 October 2022 to December 2022. Results: In one week of survey, 110 health workers (intern, obstetrician nurse, general practitioners and specialists) received the survey sheet, 80 health workers informed it, a participation rate of 73%. The male sex was most represented at 63.75% with a sex ratio of 1.76. The average age was 39.59 years with extremes of 22 and 61 years. The clinical signs evoked by the participants were: breast nodule (81.25%), followed by breast discharge (48.75%). In relation to risk factors: interns and obstetrician nurses had no good knowledge, 51.72% of general practitioners had good knowledge, 43.48% of specialist doctors had good knowledge, and 5.88% of the wise had good knowledge. Conclusion: Breast cancer is a common pathology around the world, health professionals are at the forefront of the fight against breast cancer, and this fight cannot be effective without trained personnel.

Retroperitoneal soft tissue sarcomas in the retroperitoneal/intra-abdominal regions represent 10% - 15% of all cases of soft tissue sarcoma. Liposarcomas, which are the most common histological type, account for 20% - 45% of retroperitoneal/intra-abdominal sarcoma cases, and 20% of liposarcomas cases are primary retroperitoneal liposarcomas. Surgical resection in case of malignancy remains the treatment of choice for liposarcomas, according to the guidelines of most major international companies. Our goal was to improve the management of retroperitoneal liposarcoma. This was a 65-year-old patient, with no medical or surgical history, who was referred to us for abdominal swelling, in whom clinical and paraclinical examination found retroperitoneal liposarcoma stage IV, and the surgical treatment consisted in making a tumor reduction. Conclusion: Retro-peritoneal liposarcoma is an undervalued malignant tumor, and the diagnosis is often late.

The Boulon Djounga eastern perimeter is part of the Tiawa operating permit of the Société des Mines du Liptako (SML), located in the central southwestern part of Liptako (Niger). In this study, we used field data, Reverse Circulation (RC) surveys and chemical analyzes of gold to determine the characteristics of gold and its mineralization style. The eastern perimeter of Boulon Djounga is represented by a succession of metabasalts and metasediments both intersected by intrusions of quartz and dolerite dykes, and covered by sandstone and clayey rocks. Gold is present in low contents (0.00 - 0.30 ppm) in the sedimentary cover and in medium (0.30 - 1.00 ppm) or high contents (1.00 - 4.534 ppm) in the metasediments, and in the gray quartz veins and locally in the volcanics. It exists in a disseminated state or in a concentrated state in the surrounding areas in the form of discrete grains associated with sulphurous minerals (pyrite: FeS2, chalcopyrite: CuFeS2 or arsenopyrite: FeAsS). The presence of gold in the quartz veins, and the NE-SW and NW-SE orientations of the ore bodies suggest that the eastern Boulon Djounga gold mineralization would be established during a late magmatic extensive phase.
