Top Endocrine Publications of 2013: Canine & Feline Parathyroid & Calcium Disorders

In my third compilation of the canine and feline endocrine publications of 2013, I’m moving on to disorders of the parathyroid gland, including the clinical problems of hypercalcemia and hypocalcemia.

Listed below are 21 research papers written in 2013 that deal with a variety of topics and issues related to calcium, parathyroid or vitamin D metabolism.

These range from the interactions of calcitriol, calcidiol, parathyroid hormone, and fibroblast growth factor-23 in the pathogenesis of chronic kidney disease (1) to a number of reports of dogs with hypercalcemia of malignancy (2,4,5,7,16); from a review of hypocalcemia associated with critical illness (3) to a case of reversible myocardial failure associated with primary hypoparathyroidism in a cat (6); from a study of preoperative factors that help predict iatrogenic hypoparathyroidism following parathyroid surgery (8) to reviews of the emergency management of common metabolic abnormalities, including hypocalcemia, in cats that present with collapse (9,10); and from a study of the forms of dietary potassium in the prevention of calcium oxalate urolith formation in cats (11) to the effect of bone meal on urinary calcium and oxalate excretion in cats (12).

Other papers include a review of cholecalciferol (vitamin D3) intoxication leading to hypercalcemia (13) to changes in serum concentrations of calcium, phosphorus, magnesium, parathyroid hormone, calcidiol and calcitriol in growing cats (14) to a study of the plasma calcitonin response associated with hypocalcemia in cats (15); from a study of the vitamin D status in dogs with non-neoplastic and neoplastic esophageal nodules resulting from the nematode spirocercosis (17) to a case report of hypercalcemia secondary to Addison's disease in a cat (18); and finally, from a report of 3 cats with severe hypercalcemia secondary to vitamin D intoxication caused by ingestion of commercial cat foods (19) to a case report of a Persian cat that developed hypercalcemia secondary to intra-abdominal fungal pseudomycetoma (i.e., dermatophyte penetration into the abdominal cavity) (21) .
