Introduction: Erectile Dysfunction (ED) is defined as the inability to achieve or maintain an erection sufficient for sexual intercourse. The frequency of erectile dysfunction in patients with kidney failure is estimated at 50% to 70%. The objective of this work was to determine the frequency of sexual dysfunction in chronic hemodialysis patients, to evaluate the psycho-social impact and to describe hormonal disturbances. Patients and Methods: This was a descriptive prospective study carried out from 3 April to 31 August 2017 in the nephrology and haemodialysis department of the Point G University Hospital. She has been interested in men over the age of 18 who have been on chronic hemodialysis for more than a year. Sexual dysfunction was assessed using the questionnaire: International Index of Erectile Function (IIEF-5). Results: Sixty-five patients were included. Forty-six (70.8%) had severe (30.8%), moderate (13.8%) and mild (26.2%) ED. 56.9% of patients had libido disorders, with decreased sexual desire (38.5%);absent sexual desire (18.5%). Sexual desire was normal in 43.1% of patients. Sexual activity was absent in 20 patients (30.8%). Sexual rigidity was reduced in 28 patients (43.1%) and normal in 24 patients (36.9%). The mean age of our patients was 42.55 years with a median age of 40 years and extremes of 23 and 74 years. Eighty percent were married. nine patients (13.8%) were using sildenafil-based medications. Antihypertensives were prescribed in 93.9% and erythropoietin in 30.8% of patients. The main impact groups were anxiety (53.8%), fear of failure (27.7%), insomnia (7.7%) and anxiety (6.1%). And defence mechanisms included: understanding (54.7%);isolation (24.6%);repression (7.7%);quarrel (7.7%);and divorce in 1 case (1.5%). The occurrence of ED was related to hypotestosterolemia (p = 0.030), and between low libido and testosterone (p = 0.001). nutritional status was satisfactory in 78.4% of our patients. Moderate and at and severe undernutrition was

Introduction: Chronic kidney disease (CKD) is the progressive and irreversible loss of kidney function. It exposes to many complications, among which, digestive complications. In Mali, we do not have data on the prevalence of digestive pathologies in people with chronic renal failure, hence the interest of this study. Objective: To determine the prevalence of digestive pathologies and to describe their manifestations during chronic renal failure. Patients and Methods: This was a prospective cross-sectional study conducted from September 2016 to August 2017, a period of 12 months. Included were patients hospitalized in our department with CKD who received digestive endoscopy and/or liver serology. Results: Seventy-one patients underwent digestive endoscopy with oesogastroduodenal fibroscopy (60 patients), rectoscopy (6 patients) and anoscopy (5 patients), i.e. 15.9% of those hospitalized. The mean age of the patients was 48 ± 14 years with extremes of 15 and 84 years. The sample consisted of 59.2% men versus 40.8% women, for a sex ratio of 1.5. The functional signs are in order of frequency: vomiting (72.4%), anorexia (51.3%) and epigastralgia (48.7%). Terminal CKD by creatinine clearance accounted for 88.2% of cases, of which 47.4% were monitored by hemodialysis. Hepatitis C virus infection was present in 21.3% of cases, hepatitis B (18%) and HIV (7.5%). Endoscopic examinations were represented by fibroscopy (84.5%), rectoscopy (8.5%) and anuscopy (7%). The fibroscopic lesions were respectively gastric (96.8%), duodenal (14.1%) and esophageal (12.5%). They were dominated by gastritis (40.5%), duodeno-gastric reflux (16.4%), pyloric gap (12.6%). Rectoscopy found 4 cases of hemorrhoids, 2 cases of rectitis and no lesions were observed at anuscopy. Conclusion: The prevalence of these digestive manifestations and the endoscopic lesions encountered indicate the importance of digestive endoscopy and the performance of hepatic serologies in chronic renal failure patients w

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）.

Beta-2-microglobulin (B2M) is a low molecular weight polypeptide (11,800 Da) that exists in a free form and a form bound to cell membranes (light chains of HLA class I molecules). Their dosage is used in the exploration and monitoring of renal function in haemodialysis patients, hence the interest of this study, the objective of which is to study the different players involved in the increase of beta-2-microglobulin. ng>Materials and Methods:ng> This was a prospective and descriptive study from January 1st, 2017 to August 31, 2017 (08 months). All patients with chronic hemodialysis for 3 years or more were included. We analyzed sociodemographic, clinical and paraclinical data. ng>Results:ng> We collected 50 patients. The mean age was 50 ± 4.6 years with extremes of 30 and 82 years. The female sex predominated (52%). Chronic end-stage renal failure was hypertensive (86%), diabetic (4%). All patients benefited from intermittent hemodialysis for 8 hours per week using a low permeability membrane (cuprophane). The average duration of hemodialysis was 68 ± 6.4 months with extremes of 36 and 204 months. Twenty percent (20%) and four percent (4%) of chronic dialysis patients had joint pain and sensory deficit. Phalen’s sign was positive in 2% (1 case), Tinel’s sign in 2% (1 case) and carpal tunnel syndrome in 2% (1 case). The mean serum beta-2-microglobulin level was 58.34 ng/l with extremes of 16.99 and 112.24 ng/l.

Introduction: Chronic renal failure (CKD) is defined as a glomerular filtration rate (GFR) of less than 60 ml/min/1.73m2 for more than 3 months [1]. Infectious complications are a major source of morbidity in patients with chronic renal failure. In Mali, we have no data on pneumopathies in this population, hence the interest of this study. The objective of this work was to determine the frequency of pneumopathies in patients with chronic renal failure, describe the clinical radio-types, identify the microorganisms involved, and assess the renal prognosis of pneumopathies. Materials and Methods: This was an 18-month prospective and descriptive study from January 1, 2018 to June 30, 2019 conducted in the nephrology and hemodialysis department of the University Hospital of Point G. Included were patients hospitalized during our study period with CKD associated with pneumopathy on a chest X-ray. not included were all patients hospitalized outside the study period, all CKD cases without pneumonia, patients with incomplete records, and non-consenting patients. Results: We examined 1111 patients, 35 of whom presented an image on chest X-ray related to pneumopathy, a frequency of 3.15% of cases. Twenty-one men (60%) and 14 women (40%) with a sex ratio of 1.5. The mean age was 46.8 ± 13.9 years with extremes of 23 and 76 years. The types of pneumopathy on the chest X-ray were: alveolar pneumopathy: 23 cases (65.7%), pleuropneumopathy: 10 cases (28.6%) and cavitary pneumopathy: 2 cases (5.7%). Cytobacteriological sputum examination was positive in 65.7%;leukocytes (68.6% of cases).

Adult nephrotic Syndrome (nS) is defined by proteinuria > 3 g/24h or 50 mg/kg/day, hypoprotidemia nemia n thrombosis is common, while its association with pulmonary localizations has been more rarely reported. We report a case of nephrotic syndrome revealed by an association of pulmonary embolism, renal vein and inferior vena cava thrombosis. The diagnosis was confirmed by thoracic angioscan. Renal biopsy revealed Focal Segmental Hyalinosis (FSH). An anti-coagulant treatment and an anti-proteinuric treatment were instituted based on a calcium channel blocker (amlodipine) associated with the conversion enzyme inhibitor (perindopril).

Background: The term urinary lithiasis (UL) from the Greek “lithos” refers to the disease characterised by the result of abnormal precipitation of normal constituents of the urine within the urinary tract. The aim of this work was to determine the frequency of obstructive renal failure (ORF) of lithiasis origin and to describe the therapeutic indications. Methods: This was a retrospective prospective study in patients hospitalised in the nephrology department of Point G University Hospital for ORF of lithiasis origin over a 26-month period from 1 January 2018 to 1 February 2020 inclusive. Results: Among 1898 hospitalized patients, 32 met the inclusion criteria, i.e. a frequency of 1.7%. The male sex was 68.75% with a sex ratio of 2.2. The mean age was 48.38 ± 13.423 years with extremes of 20 and 65 years. Dysuria and urinary bilharzia were the main uro-nephrological antecedents, accounting for 25% of the cases each. Pain syndrome was the main functional sign, accounting for 100%. Ultrasound of the urinary tract (n = 28) showed stones in 92.85%. These stones were bilateral in 22.22% of cases. The dilatation was pyelocalic in 14 cases (51.8%). The uroscanner showed a pyelic location of the stones in both kidneys;42.1% on the right and 33.3% on the left. Hydronephrosis was the most common dilatation: 37.8% on the right and 29.7% on the left. Renal lithiasis was complicated by acute kidney injury (ARI) in 17 cases (53.1%) versus 15 cases (46.9%) of chronic kidney disease (CKD). Urethral catheter was the means of drainage in 24 (75%) followed by nephrostomy in 8 cases (25%). nephrolithotomy accounted for 9.4% of cases. The case fatality rate was 28.12% (9 cases). Deaths occurred in the context of uraemic coma 6 cases and cardiorespiratory arrest 3 cases. Conclusions: The management of urinary lithiasis complicated by renal failure calls for the correction of hydrolytic disorders, drainage of the excretory tract and treatment of the stone, of which percutaneous nephrolith

The picture achieved associated massive proteinuria, hypoalbuminemia, moderate renal failure and edematous syndrome in men. In women, the picture was associated with accelerated to malignant hypertension and severe renal failure.

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
