Impaired differential renal function in a child with pheochromocytoma

Allopurinol in patients with impaired renal function.

Pharmacokinetics of enfuvirtide in a patient with impaired renal function.

Enfuvirtide is the first member of the fourth class of antiretroviral drugs to become available. We present a case report of a human immunodeficiency virus (HIV)-positive patient with mild renal impairment who developed severe renal impairment secondary to tenofovir therapy while receiving enfuvirtide. Because the patient's pharmacokinetic profile was not significantly altered, compared with th...

Distal Renal Tubular Acidosis with Grade 4 Vesicoureteral Reflux in a Child with Single Kidney

  Introduction Renal tubular acidosis (RTA) is a non-uremic defects of urinary acidification. It is characterized by a normal anion gap hyperchloremic  metabolic acidosis; plasma potassium may be normal, low or high-depending on the type of RTA. These syndromes differ from uremic acidosis which is associated with a high anion gap, decreased glomerular filtration with enhanced proton secretion b...

Anticoagulation in patients with impaired renal function and with haemodialysis.

Patients with impaired renal function are exposed to an increased risk for bleeding complications depending on the amount of the anticoagulant eliminated by the kidneys. The elimination of unfractionated heparins, vitamin K antagonists and argatroban is only minimally influenced by a reduced renal function. Low-molecular weight heparins, fondaparinux, danaparoid, hirudins and nonvitamin K antag...

Enterocolitis with peritonitis in a child with pheochromocytoma.

An 8-year-old boy presented at UCLA Hospital with a one month history of hypertension prior to suffering a sudden onset of acute abdominal pain, rectal bleeding, peritonitis, and shock. Sigmoidoscopy showed diffuse mucosal friability. At laparotomy, inflammation and edema of the entire colon and terminal ileum were detected with two necrotic areas on the cecum. A 5 cm right adrenal pheochromocy...
