Renal abnormalities in sickle cell disease. Sickle cell nephropathy is indicated by sickled erythrocytes, with the consequent effects of decreased medullary blood flow, ischemia, microinfarct and papillary necrosis. Impaired urinary concentrating ability, renal acidification, hematuria, and potassium secretion are also found. There may be a causal(More)
Both peritoneal dialysis (PD) and hemodialysis (HD) patients have diminished quality of life (QOL) scores compared to healthy patients. QOL tends to decline over time, with the perception of the quality of physical health deteriorating more than mental health. However, many patients continue to feel hopeless, anxious, and worry about finances, loss of(More)
Significant technological changes in blood flow rate, dialyzer membrane permeability, bicarbonate dialysate, and ultrafiltration-controlled delivery systems permitted the implementation of 3 modifications to conventional hemodialysis as follows: high-efficiency hemodialysis (HEHD), high-flux hemodialysis (HFHD), and double-high-flux hemodiafiltration (HDF).(More)

Hydrothorax in a patient treated with peritoneal dialysis (PD) poses a diagnostic dilemma. Hydrothorax due to migration of dialysis fluid across the diaphragm and into the pleural space creates a serious complication of PD but generally does not threaten life. Shortness of breath causes the patient to seek medical attention. A sudden diminution in dialysis(More)
We present two cases of non-resolving peritonitis treated with a standard peritonitis protocol. The organism identified from the peritoneal effluent was Mycobacterium fortuitum, a group IV (Runyon's classification) rapidly growing, nontuberculous mycobacterium. M. fortuitum is ubiquitous and can be isolated from a number of natural sources. Risk factors(More)
Many patients with end-stage renal disease who are on maintenance hemodialysis still have significant residual renal function. Exogenous markers such as inulin and radionuclides, and endogenous markers such as creatinine and urea are commonly used to quantify this residual function. These various methods are described in detail and compared with one(More)
Gender differences exist in hypertension, the prevalence of several renal diseases, progression of established renal disease, and within the ESRD program, including renal transplantation. Sex hormones play key roles in the pathogenesis and outcome of disease processes. Observational data suggest gender differences in the prevalence and outcome of several(More)
Infection is a common cause of morbidity and mortality in end-stage renal disease patients. Unintentional pathogens are introduced into an immunocompromised host during hemodialysis and peritoneal dialysis by means of the access (arteriovenous fistula, arteriovenous graft, central venous catheter, or peritoneal dialysis catheter). Gram positive organisms(More)
