The role of aldosterone has expanded from the hormone's genomic effects that involve renal sodium transport to nongenomic effects that are independent of the effect of aldosterone on sodium transport. The nongenomic effects of aldosterone to increase fibrosis, collagen deposition, inflammation, and remodeling of the heart and blood vessels, however, are(More)
PURPOSE OF REVIEW Recent studies have consistently demonstrated the common prevalence of hyponatremia in the hospital and intensive care settings, and how it correlates with untoward outcomes. This review discusses the classification, diagnosis, and pathophysiology of hyponatremia and how these agents may influence its management, and also examines the(More)
Renal cysts, pain, and hematuria are common presentations of autosomal dominant polycystic kidney disease (ADPKD) in children. Renal function, however, is typically preserved in these patients despite increased renal volume. Since angiogenesis has been implicated in promotion of renal cyst growth in ADPKD, we measured the serum level of various angiogenic(More)
BACKGROUND End-stage renal disease is a significant social and economic burden on the Sudan. Continuous ambulatory peritoneal dialysis (CAPD) was recently introduced as a national service and is provided free of charge by the Federal State. We present here an overview of our experience and outcomes after the first 20 months of operation of the National(More)
The pathogenesis of cardiac failure involves activation of the neurohumoral axis including stimulation of the sympathetic nervous system, the renin-angiotensin-aldosterone, and nonosmotic vasopressin systems. While these responses are critical in maintaining arterial pressure, they are associated with renal vasoconstriction, as well as sodium and water(More)
This is a cumulative report of all patients in six centers in Greater Khartoum, all three cities that comprise the capital of Sudan, covering the first year of operation of the National Program. This study evaluates the rates, mechanisms, causative agents and clinical outcomes of peritonitis. We included the data of all 60 patients who underwent CAPD from(More)
The African Programme for Onchocerciasis Control (APOC) sponsored a baseline study in Nigeria between 1998 and 1999 on the prevalence and distribution of Onchocerciasis. The randomly selected 1,064 subjects in the baseline study underwent detailed eye examination in Cross River (rain forest), Taraba (savanna) and Kogi (forest-savanna) States. This paper(More)
BACKGROUND A 40-year-old male from the White Nile region in Sudan, who had received a kidney transplant 6 years previously, presented with fever, lower abdominal pain and diarrhea stained with blood of 5 months duration. He was on immunosuppressive maintenance therapy, consisting of ciclosporin 75 mg twice daily, prednisolone 10 mg once daily, and(More)
Autosomal dominant polycystic kidney disease (ADPKD) is the most common life-threatening hereditary disease of the kidney. It presents with progressive enlargement of the kidneys with numerous cysts that distort the parenchyma and result in progressive decline in kidney function. Autosomal dominant polycystic kidney disease is genetically modified with the(More)
