A40-year-old man with primary oxalosis, nephrocalcinosis, severe renal failure, and a permanent dual-chamber pacemaker due to intermittent complete atrioventricular block was admitted to the hospital because of increasing dyspnea. His chest x-ray showed an increased cardiothoracic ratio, pulmonary venous congestion, and bilateral pleural effusions. ECG demonstrated sinus tachycardia at 97 bpm w...

Oxalosis is a disease caused by the deposition of calcium oxalate in extrarenal tissues, most commonly bone, myocardium, retina, blood vessels, and skin, causing the clinical manifestations of the disease. Involvement of the blood vessels of the skin can give rise to livedo reticularis, acrocyanosis, ulcers, and gangrene. We present the case of a 60-year-old woman with a history of recurrent re...

BACKGROUND Oxalosis is a metabolic disorder characterized by deposition of oxalate crystals in various organs including the kidney. Whereas primary forms result from genetic defects in oxalate metabolism, secondary forms of oxalosis can result from excessive intestinal oxalate absorption or increased endogenous production, e.g. after intoxication with ethylene glycol. CASE PRESENTATION Here, ...

A 27-year-old man with primary oxalosis and extensive visceral involvement was maintained on long-term chronic hemodialysis. He had an episode of presyncope associated with electrocardiographic findings of an erratic atrial rhythm, atrioventricular dissociation due to an accelerated junctional rhythm and right bundle branch block. Electrophysiologic studies showed irregular atrial depolarizatio...
