Objective: Description of a cat with ischemic muscle necrosis that suffered from cardiopulmonary arrest due to hyperkalemia. Pathogenesis, clinical signs and therapy of ischemic muscle necrosis are discussed and possible causes, symptoms and treatment of hyperkalemia are shown. Material and methods: case report of a four-year-old male castrated domestic shorthair cat. Results: The cat was successfully resuscitated and hyperkalemia was treated with different treatment modalities. Conclusion: Ischemic muscle necrosis can lead to severe live-threatening hyperkalemia which has to be anticipated, monitored and treated adequately. Aggressive fluid therapy might be responsible for a higher risk of hyperkalemia in predisposed cases. Clinical relevance: Potassium concentrations and acid-base disturbances must be closely monitored in patients with ischemic muscle necrosis

We report the case of a 79 year old woman presenting with progressive confusion and drowsiness. Renal insufficiency with hyperkalemia as well as hypercalcemia and severe hyperphosphatemia were diagnosed. Renal insufficiency improved with treatment. However, hyperphosphatemia persisted without apparent explanation. We discuss possible causes of hyper- and pseudohyperphosphatemia. Specifically, phosphate analysis may be disturbed by the paraproteins in patients with multiple myeloma, resulting in pseudohyperphosphatemia. We review the standard laboratory phosphate measurement and the mechanisms of interference with paraproteins.
