Radiocontrast-induced renal failure.

Review of the literature concerning contrast-induced renal dysfunction shows that the currently used agents are remarkably safe with careful patient selection. Clinically apparent kidney failure after their use is essentially nonexistent in those without preexistent renal insufficiency. The incidence rises rapidly in those with azotemia from any cause, however, and diabetic persons with nephropathy are perhaps at special risk.

Comparison of blood pressure, plasma lipid and cardiac performance responses to prazosin versus propranolol in thiazide-treated hypertensive patients.

Twenty-seven patients with uncontrolled hypertension (diastolic blood pressure greater than or equal to 95 mm Hg) receiving thiazide diuretics were treated with the addition of either propranolol (n = 10) or prazosin (n = 17). Nine patients were successfully controlled with propranolol and 12 with prazosin. Six patients required both study drugs for optimal blood pressure control, 5 of whom had received prazosin as the initial study drug.
