Marked electrolyte abnormalities characterized by profound hyperkalemia, hyponatremia, hypocalcemia, and hyperphosphatemia were noted in 4 neonatal foals with acute rhabdomyolysis and pigmenturia. In 2 foals, rhabdomyolysis developed 4-6 days after admission for dysmaturity, and in 2 foals, rhabdomyolysis was evident on presentation. Rhabdomyolysis was a consequence of selenium deficiency with or without vitamin E deficiency, possibly combined with increased oxidant stress due to sepsis or hypoxia and reperfusion injury after parturition. Foals gained from 7 to 15% of their initial body weight within 48 hours of developing rhabdomyolysis. Three of the foals developed cardiac arrhythmias characterized by spiked T waves and decreased-amplitude P waves. Postmortem examination of 2 foals revealed extensive myodegeneration and renal tubular nephrosis; renal cortical necrosis with myocardial necrosis was noted in 1 foal. Destruction of the major intracellular compartment (intracellular fluid [ICF]) through extensive myonecrosis combined, in some cases, with myoglobinuric renal insufficiency produced major fluid shifts and life-threatening electrolyte derangements. With the major ICF compartment disrupted, hyperkalemia was most effectively treated using mineralocorticoids, loop diuretics, and ion exchange resins to enhance elimination. In addition, i.v. calcium, glucose, insulin, and sodium bicarbonate were administered, which helped redistribute potassium to the ICF. Severe rhabdomyolysis should be included in the differential diagnoses of hyperkalemia, hyponatremia, hypocalcemia, and hyperphosphatemia in neonatal foals.

A free-ranging juvenile female red-tailed hawk (Buteo jamaicensis) that was unable to fly was admitted to a rehabilitation center and died 1 day later. Hematology and serum chemistry abnormalities included moderate regenerative anemia, elevated creatine kinase, and hyperphosphatemia. Necropsy revealed a generalized steatitis, and histology showed a necrotizing and granulomatous pansteatitis with intralesional pigment compatible with ceroid. There was also moderate diffuse myodegeneration, mild multifocal cardiomyopathy, and mild multifocal hepatic necrosis. These changes and lesions resemble those caused by vitamin E deficiency in mammals and fish-eating birds.
