Abstract: Introduction: Chronic renal failure is a disease that affects many patients worldwide and increasingly in Africa. At the end of 2003, about 1.1 million people were suffering from End-Stage Renal Disease (ESRD) and were treated with periodic dialysis [12]. In Africa, CKF represents 2% to 10% of hospital admissions and is responsible for 4% to 22% of deaths [14]. So, this study is conducted for the first time in Chad, with the aims to determine the prevalence of CKD. Methods: This was a retrospective, descriptive and analytical study over a period of 12 months from April 29, 2011 to April 28, 2012. All patients with chronic renal failure regardless of etiology and stage of chronic kidney disease were included in the study. Chronic renal failure was defined as a glomerular filtration rate below 60 ml/min/1.73m (MDRD) for more than 3 months. This study was conducted in several departments of the National General Reference Hospital (NGRH) of N’Djamena. Result: Among 2039 inpatients, 195 patients had chronic renal failure, as a frequency of 9.6%. The average age of our patients was 51 ± 16.8 years, ranging from 11 to 85 years. Male predominance was noted to be 59% of men against 41% of women. We noted that high blood pressure accounted for 66.2% (N = 129) of cases, diabetes in 48.2% (N = 94), alcoholism in 28.7% (N = 56), smoking in 14.9% (N = 29) and the association alcoholism-smoking in 19.5% (N = 38). Hypertension was the leading cause of chronic renal failure (66.2%). All patients had a serum creatinine and creatinine clearance was assessed. Among them, we noted 57 patients (29%) with end-stage renal failure. The average calcium and phosphate serum were 1.8 mmol/l and 1.6 mmol/l, respectively. We noted that 120 patients as 61.5%, currently took herbal medicine. 48 out of 57 of our patients with ESRD as 24.6% of patients in the study had received replacement therapy (hemodialysis) with 12.5% of deaths. Conclusion: Chad, who compiled the first study with 195 patients at the General Hospital of N’Djamena National Reference over a period of one year has objectified a prevalence of chronic renal failure of 9.6%.

Abstract: Introduction: Hyperuricemia is defined as a level of serum uric acid greater than or equal to 70 mg/l (420 μmol/l) in men and 60 mg/l (360 μmol/l) in women. Several studies have shown that it is a risk factor or a factor of progression of chronic kidney disease. Recent experimental and epidemiological data correlate the association of hyperuricemia with chronic kidney disease (CKD), arterial hypertension and cardiovascular diseases, thus raising the question of the usefulness of therapeutics in the prevention of renal diseases. The objective of this study is to seek a link between chronic kidney disease and hyperuricemia. Materials and Methods: This is a descriptive and analytical study conducted at hemodialysis unit and cardiology service of General Hospital of National reference of N’Djamena (Chad) from 1th January to 1th October 2013 (10 months). We included all chronic kidney disease patients hospitalized in hemodialysis unit and cardiology service who presented associated hyperuricemia. Results: There were 712 CKD patients who were hospitalized. Among them, there were 108 patients who were included in the study and who had hyperuricemia as a prevalence of 15.20%. The average age of patients was 35.5 years and the sex ratio was 3/1. The age group between 40 to 60 years represented 54.6%. There were 41.7% of traders. Hypertensive patients accounted for 49.1%; association of diabetes and hypertension was noted in 12.90%. Renal insufficiency was moderate in 43.5% of patients. Hyperuricemia was present in more than 90% of patients. Profession, age, hematuria, proteinuria and hypertension were statistically positively related to hyperuricemia. Treatment consisted of prescribing allopurinol in 84% of patients. In more than 11% of patients the progression was unfavorable. Conclusion: The implication of hyperuricemia in chronic kidney disease has been proved in several recent studies. However, randomized studies at very long scales have to be carried out to conclude from its real impact on the prevention and treatment of chronic kidney disease.

Abstract: Introduction: In malaria-endemic areas, acute renal failure (ARF) is one of the most serious complications, it occurs in 40% of severe forms of malaria in adults and is linked to 75% of deaths, especially when extra-renal cleaning is not available. In children, studies of ARF during malaria are limited. We have no published studies on this topic in Niger. The main objective of our study is to evaluate the prognosis of ARF during severe malaria in children. Patients and Method: This is a one-year prospective study (January 1, 2016 to December 31, 2016) conducted in the resuscitation unit of the pediatric department of the National Lamordé Hospital of Niamey (Niger). We included in the study children aged 0 to 15 years hospitalized for severe malaria with impaired renal function. Patients who had chronic renal failure or who had acute renal failure with a thick negative drop were excluded from the study. Acute renal failure is defined according to Kidney Disease Improving Global Outcomes (KDIGO) criteria basing on creatinine clearance. Results: The incidence of ARF was 12.60%. The mean age of the patients was 4.25 ± 1.3 years [8 months - 15 years]. The mean hemoglobin level was 8.2 ± 2.7 g/dl. In 54.02% of cases, the hemoglobin level is ≤5 g/dl. Mean serum creatinine was 543.7 ± 69.5 μmol/l [107 - 2500 μmol/l] and mean azotemia was 27.5 ± 3.5 mmol/l. Severe anemia (54.02%) were more related to the occurrence of ARF(with p = 0.014). According to the RIFLE classification, 55 patients (63.22%) were in the Risk stage, 18 patients (20.69%) were in the injury stage and 14 patients (16.09%) in the failure stage. All patients were placed on injectable Artesunate. The average length of hospital stay was 8.6 ± 4.5 days [5 to 22 days]. Dialysis was reported in 15/87 (17.24%). For technical and financial reasons only 8 patients were hemodialysed. Indications for dialysis were severe uremic syndrome 7 cases (8.04%), fluid overload 5 cases (5.75%) and severe hyperkalemia 3 cases (3.45%). Conclusion: The etiological factors of ARI in malaria were massive hemoglobinuria, severe anemia and shock. Adequate management of simple cases of malaria and the early transfer of severe cases to resuscitation services can prevent certain complications such as acute renal failure.

Abstract: Objective: To describe clinical, biological and evolutionary profile of Acute Kidney Injury (AKI) due to Severe Malaria in the pediatric department. Methodology: This was a retrospective descriptive study that took place from January to December 2012. It has been included children aged 0 - 15 years admitted for severe malaria with positive thick drop. AKI was defined by using the modified RIFLE (Risk Injury Failure Loss End stage) classification for Pediatrics. Results: 338 children admitted for severe malaria were included. AKI was diagnosed in 24 children, a prevalence of 7.1% according to pRIFLE classification: RISK in 10 (3%), INJURY in 9 (2.6%) and FAILURE in 5 (1.5%). The average age was 8.16 ± 4.2 years. Clinical features were dominated by hemoglobinuria in 87.5%, oliguria, vomiting and fever in 75%. The biological features were dominated by severe anemia (Hb < 6 g/dl) in 79.2% of cases. Hyperkalemia (K > 5.5 mmol/l) was found in 2 cases. The mean parasitic density was 22,120 trophozoites. Malaria was treated primarily with artemether in 83.3% of the cases. Dialysis was indicated in 2 cases for menacing hyperkalaemia, but was not done because of lack of financial means. In one case, hyperkalaemia was successfully treated with symptomatic measures, but in the second case, these measures were not allowed to normalize kalaemia, and death occurred. Conclusion: Acute post-malarial renal failure secondary to tubular necrosis may be the dominant clinical features of severe malaria. Death may occur. Preventing malaria would be the best way to avoid it.

Abstract: Introduction: The incidence of acute renal injury (AKI) has increased in recent decades. Acute renal failure is defined by the abrupt arrest (within hours or days) of the kidney excretory function. Oliguria (urine output <400 ml/ 24h) is presented in about half of the cases. The circumstances of the occurrence of AKI are multiple: surgical, traumatic, obstetric, medical, often obvious. Its prognosis depends on the speed of management and the associated organ failure. The objective of this study is to describe the profile of patients in emergency hemodialysis at the Nephrology Unit of the National Reference General Hospital (HGRN) in N’Djamena, Chad. Methods: This was a multicenter, descriptive study in patients with acute renal failure place over a period of 12 months in the emergency departments of the 2 hospitals in N’Djamena. Defined as carriers of an AKI (RIFLE criteria), patients with: 1) Oliguria: urinary output < 400 ml/24h (<0.5 ml/kg/h in children) or anuria: urinary output < 300 ml/24h; 2) Associated with an increase in serum creatinine: serum creatinine × 3 or serum creatinine> 350 μmol/l or decrease of GFR by 75%. Results: Of the 311 patients admitted, 36 cases met the inclusion criteria, a frequency of 11.57%. The mean age was 34.46 years with extremes ranging from 7 to 80 years. The female sex predominated with 52.80% as sex ratio of 0.91. Isolated hypertension was noted with 38.88%. Dyspnea accounted for 41.66% of patients admitted to emergency departments. In our series, 50% of our patients had hyperthermia at admission. Oliguria was observed in 41.70% of the cases. Edema accounted for 33.33% of cases. The AKI with the failure criterion was 58.34% (21/36), with the criterion “injury” 25% (9 cases) and the criterion “risk” 16.66 (6 cases). AKI were organic in 83.34% (30/36). It was noted that 14 patients, 38.8% had an infectious syndrome. There were 6 patients who had (16.66%) an obstructive AKI, 5

Abstract: Introduction: Human immunodeficiency virus (HIV) infection is a common cause of kidney disease worldwide. HIV-related renal diseases are associated with high morbidity and mortality in Sub-Saharan African countries. The aim is to describe the epidemiological, clinical and biological aspects of kidney disease in people living with HIV naive antiretroviral therapy in Lomé in Togo. Methods: This was a cross-sectional study done in the department of Infectious and Tropical Diseases in Lomé from ESOPE database. Glomerular filtration rate (GFR) was calculated using the Modification of Diet in Renal Disease (MDRD) equation. Kidney disease was defined as GFR less than 90 mL/min/1.73 m2. Results: In total, 3118 HIV-infected ART-naive patients were included in this study. Among them, the prevalence of renal disease at the beginning of their care, was 41.8% or 1303 patients [95% CI: 40.0% - 43.5%]. The median estimated GFR was 94.7 ml/min/1.73 m2: 2.9% had eGFR < 15 ml/min/1.73 m2. The median age was 40 years [IQR = 34 - 48 years] with a sex ratio at 0.45. BMI median was 20.6 Kg/m2. Most of patients (30.8%) were at clinic OMS stage 1. Median CD4 was 165/uL [IQR = 72 - 274/uL]; median hemoglobin was 10.4 g/dl [IQR = 8.8 - 11.9 g/dl]; median glycemia was 0.84 g/l [IQR = 0.75 - 0.95 g/l]. Most of patients (99.9%) had HIV-1. 8.5% had hyperleukocytosis, and all patients had thrombopenia. Conclusion: The incidence of kidney disease is high in Togolese HIV-infected ART naive patients.

Research Journal of Applied Sciences , 2012, DOI: 10.3923/rjasci.2011.381.386
Abstract: Course Management Systems (CMSs) are becoming more important within the higher education scenario. However, the main weakness of these systems is that they are built for general use without taking into consideration the peculiarities of each discipline. This research describes a study on the needs of ESL instructors in selected Malaysian institutions of higher learning when it comes to course management systems. The findings indicate that it is very important to cater to the needs of the target users of CMSs especially the requirements for the discipline or subject. The respondents also rate communications and collaboration as important as well. This study finally present some design features based on the findings of the study.

Abstract: Difference equations or discrete dynamical systems is diverse field whose impact almost every branch of pure and ap- plied mathematics. Every dynamical system an+1=f(an) determines a difference equation and vise versa. We ob-tain in this paper the solution and periodicity of the following difference equation. xn+1=(xnxn-2xn-4)/(xn-1xn-3xn-5, (1) n=0,1,... where the initial conditions x-5,x-4,x-3,x-2,x-1 and x0 are arbitrary real numbers with x-1,x-3 and x-5 not equal to be zero. On the other hand, we will study the local stability of the solutions of Equation (1). Moreover, we give graphically the behavior of some numerical examples for this difference equation with some initial conditions.
