The aim of this study was to report a case of multi-visceral sarcoidosis at the Mother-Child Hospital Center (CHME) “Le Luxembourg” in Bamako, Mali. Observation: This is a patient aged 62 at the time of consultation, a housewife, residing in the Banconi district, who was referred to us for thoracic-abdominopelvic imaging for chronic liver disease. After several diagnostic errors, the thoracic-abdominopelvic CT scan and liver MRI performed in our center showed, at the thoracoabdominal level, bilateral diffuse pulmonary micronodules and bilateral mediastinal-hilar lymphadenopathy;on the abdominal level, a dysmorphic liver with plaques of steatosis and a granular appearance of the liver parenchyma without periportal fibrosis. These imaging data combined with those from the liver nodule biopsy and biology confirmed the diagnosis of sarcoidosis type II. Treatment with corticosteroids gave satisfactory results and the patient recovered after 18 months. Clinical and CT monitoring 2 years from the start of the disease and 2 months from the end of treatment showed complete resolution of the lesions. Conclusion: The multi-visceral location of sarcoidosis is an entity whose diagnosis remains difficult;diagnostic and interventional imaging has an important place in its management.

Introduction: Infertility is the inability to achieve pregnancy after 12 months of regular, unprotected sexual intercourse by a couple of childbearing age. It is a real public health problem because of its high prevalence in both developed and developing countries. Female infertility occupies a prominent place in reproductive health in Africa such as in our country Mali. The objective of this work was to determine the hysterosalpingography profile of utero-tubal lesions in the etiological research of female infertility in Mopti. Materials and Method: This was a cross-sectional descriptive study covering a period of one year from January 2019 to December 2019 in the radiology department of Sominé Dolo Hospital in Mopti. The variables analyzed were patient age and hysterosalpingography results. The hysterosalpingography examination was performed 3 or 4 days after menstruation on a remote-controlled table under fluoroscopic control. Data analysis was done with the aid of SPSS version 22 and Excel 2016 software. Results: During the study period, 9012 patients were seen in the imaging department, including 115 patients, or 1.3% for infertility assessment. The 25 - 29 age group was the most represented with 34 patients or 29.6%. The mean was 30.39 ± 6.96 years with extremes of 17 and 46 years. Tubal abnormalities represented 45 cases or 39.1%. Hydrosalpinx was the most prevalent with 26 cases or 36.6%. Conclusion: Tubal lesions were the most observed, especially hydrosalpinx following. Hysterosalpingography remains the first choice in the radiological assessment of female infertility in our context.

Intrasellar arachnoidocele is a herniation of the optochiasmatic cistern through a dehiscence of the sellar diaphragm producing an empty sella turcica, hence its name empty sella turcica syndrome. It is an extremely rare benign malformative pathology. We report a case of intra-sellar arachnoidocele in a 34-year-old woman revealed during an annual control of a sellar mass under dossinex by cerebral magnetic resonance imaging (MRI) which found the cystic formation of liquid signal identical to that of the LCS in hypo signal T1 and hyper signal T2 without enhancement after injection of Gadolinium. The epidemiological, clinical and radiological aspects of arachnoidocele were analyzed. The purpose of this work is to bring the interest of MRI in the management of this pathology.

Breast pathology is varied, bringing together tumor and non-tumor lesions. Objective: To study the contribution of the ultrasound-mammography pair in the diagnosis of breast pathologies. Materials and Method: This was a retrospective descriptive study, carried out over a period of 3 years (from January 2018 to December 2020) at the Diagnostic Imaging Center (C.I.D) “TERIYA” in BAMAKO. It concerned all patients who came for a mammogram/ultrasound examination of the breast. All women admitted for mammogram or breast ultrasound who were diagnosed with a breast injury during the study period were included. Incomplete records and radiological checks were not included. The variables analyzed were age, sex, clinical data, and ultrasound and mammography aspects. The devices used are: a Voluson 730 PRO ultrasound machine and a G 600T type mammography machine. Results: At the end of our study, we collected 254 breast pathologies on a number of 382 women, i.e. a frequency of 66.49%. The average age of our patients was 41 years old. The dominant clinical data were mastodynia (41.88%) and mammary nodule (21.70%). On imaging (mammo-ultrasound) the lesions predominated on the left in 36% of cases, bilateral in 28% of cases and in the upper-outer quadrants in 31.5% of cases. Tumor pathologies represented 66.54% of which 45.27% were benign mainly composed of fibro-adenoma (20.88%) and cyst (18.50%), 11.8% of suspected cases and 9.45% of cancers. non-tumor pathologies represented 33.46%, mainly mastitis (16.14%), galactophoric dilations (11.02%) and abscesses (5.51%). These pathologies were classified in 50.3% in ACR2, 17.75% in ACR3 and 4, and in 14.20% in ACR5. Lymphadenopathy was present in 73.21% of cases.

Abdominal wall malformations correspond to a wide spectrum of congenital anomalies that are due to a defect in the closure of the anterior abdominal wall and can be fatal. We report the case of laparoschisis associated with a poly malformation syndrome in the same fetus at the reference health center of commune III of the district of Bamako. The objective is to clarify the interest of antenatal ultrasound in the diagnosis and prognosis of these malformations. It was a 19-year-old prim gravid woman received as part of the prenatal check-up. Antenatal ultrasound had allowed the diagnosis of malformation of the anterior abdominal wall of the gastroschisis type associated with abnormalities of the neural tube, the urogenital system and the bone skeleton. The antenatal diagnosis of the malformations had motivated the realization of a therapeutic termination of pregnancy at 19 weeks of amenorrhea and 3 days by triggering and vaginal delivery, allowing the confirmation of the diagnosis of gastroschisis and the poly malformation syndrome which is extremely rare. Antenatal ultrasound remains an ideal means of imaging for monitoring pregnancy and had made it possible to make the prognosis and antenatal diagnosis of multiple malformations in association, and to indicate better therapeutic decision-making.

Here we demonstrate a theory-driven, novel dual-shell coating system of Li_(2)SrSiO_(4) and Al_(2)O_(3), achieved via a facile and scalable sol-gel technique on LiCoO_(2) electrode particles. The optimal thickness of each coating can lead to increased specific capacity(~185 m Ah/g at 0.5 C-rate) at a cut-off potential of 4.5 V, and greater cycling stability at very high C rates(up to 10 C) in half-cells with lithium metal. The mechanism of this superior performance was investigated using a combination of X-ray and electron characterization methods. It shows that the results of this investigation can inform future studies to identify still better dual-shell coating schemes, achieved by such industrially feasible techniques, for application on similar, nickel-rich cathode materials.

Despite enormous efforts to achieve the goal of eliminating mother-to-child transmission of HIV-1, it remains a major challenge for many countries in sub-Saharan Africa, particularly Mali. Our objective is to assess changes in the rate of mother-to-child transmission of HIV-1. We conducted a cross-sectional study between January 1, 2009 to December 31, 2018 (10 years) of early diagnosis activity in newborns and children born to HIV-1-positive mothers at the national Institute for Public Health (InSP). The samples came from health and referral centers in mali. All samples were received at the Laboratory of Molecular Biology at the InSP. Proviral DnA extraction was performed from a blood spot sample with a Roche DnA kit, Cobas AmpliPrep/Cobas TaqMan HIV-1 qualitative Test, V2.0 (Roche Molecular System, Inc, USA) following the company procedures. Molecular diagnosis was performed using the same kits using an algorithm of three identical PCRs. The Epi Info version 7 software was used for data analysis with a significance threshold of 5%. A total of 10,714 samples of infants and children born to HIV-positive mothers were analyzed by PCR. ninety-six percent of mothers were on ARV prophylaxis (AZT 3TC nVP and AZT nVP) and 60% of newborns received the same ARV prophylaxis. Of these children, 956 tested positive with an overall transmission rate of 8.92%, varying between 7.27% in 2009 and 08.01% in 2018. This rate was relatively low among children receiving prophylaxis at 2.04% and remained high for children who received breastfeeding at 5.62%. However, the transmission rate remains low for those who have benefited from mixed and artificial breastfeeding at 1.58% and 1.27% respectively. A significant proportion of children remained infected by their mothers during pregnancy, childbirth or breastfeeding. This study shows the importance of early diagnosis of HIV in children using molecular technology.

Sprinkler Irrigation and Soil Tillage Practices in Sugarcane Plantations as Influenced by Soil Texture and Water Storage in northern Ivory Coast

引用

Journal of Life Sciences 2013年第3期7卷 293-301页

作者： Crepin B. Pene, Souleymane n'diaye Chantal n'Guessan-Konan Department of R&D SUCAFCI/SOMDIAA Sugar Mills 33 rue des Brasseurs O1 P.O. Box 1967 Abidjan 01 Ivory Coast

Soil survey investigations were carried out in Ferk6 1 as well as Ferk6 2 sugar mills of northern Ivory Coast to determine soil texture and water storage capacity for sprinkler irrigation and tillage management. A 5-year term observation experiment on reduced tillage compared with conventional tillage was also conducted in Ferk6 1 over an irrigated cane crop of 28 ha for yield optimization purpose. Soil sampling was achieved after harvest or prior to re-plantation at five different spots along two transects over 30 cm depth in every farmland which covers about 30-40 ha with 432 m long cane rows as to get an average soil sample of 1.5-2 kg. Soil physical properties like texture and water retention curves were determined locally in the sugar company＇s soil laboratory. It came out that the majority of soils investigated was coarse-textured for about 64% in Ferk6 1 and 85% in Ferk6 2, with a lower to medium water storage capacity （70-89 mm） over 60 cm depth which corresponds to a readily available moisture less than 60 mm. Except for the sugarcane plant crop, no significant difference in cane yields resulting from tillage practices was observed over four consecutive cropping seasons. The yield decline from plant cane to first ratoon was very high under conventional tillage （-16 t/ha） compared with the reduced tillage （＋3 t/ha）. Even higher cane yield was obtained on the second ratoon （89 t/ha） compared with the conventional tillage （83 t/ha）.

Recent petro-structural investigations on the Faboula gold deposit located in the Bougouni-Kékoro basin, in southern Mali, north-west of the Leo-Man Shield, have provided new data on the nature and spatial organization of the lithostratigraphic units as well as their deformation style. The deposit is covered by a thick lateritic layer and is hosted by a metavolcano-sedimentary sequence of Paleoproterozoic age intersected by intrusive bodies and filled fractures of various shapen>n>sn>n> and typen>n>sn>n>. The lithostratigraphic units consist of metagreywackes, metasiltstones, meta-argillites, slates and schists. Metagreywackes and metasiltstones are generally feldspathic, both may contain biotite and locally amphibole, just as slates may contain andalusite which is locally stretched. Plutonic units most often occur as stocks or as dikes on the drill core, up to 1 m. The metavolcano-sedimentary rocks are schistose and deformed under greenschist facies conditions, n>n>and n>n>locally they reach the epidote-amphibolite facies. The structural study revealed that the deposit is affected by several stages of deformation evolving from a ductile type to a brittle type via a ductile-brittle type. The dominant ductile and brittle-ductile deformations show a combination of isoclinal folding and strike-slip faults. Both the isoclinal folding and the strike-slip faults whose sigmoidal en-echelon tension gashes indicate a dextral movement in the nnE-SSW direction are the result of the same EnE-WSW regional shortening. Consequently, they highlight a transpressive deformation. This deformation noted here D2Fb, could
