True diaphragmatic hernia in a cat.

A report of a cat with a true diaphragmatic hernia in which only falciform fat had herniated is presented. The lesion was misinterpreted as a pulmonary mass. Additional radiographic studies which may have been of diagnostic benefit are briefly discussed.

Atypical Addison's disease in the dog: a retrospective survey of 14 cases.

Fourteen dogs diagnosed with Addison's disease and having atypical serum electrolyte levels are described. Seventy-eight percent were female, and most showed signs of inappetence, weakness, or vomiting. Ninety-three percent of the cases had either hyponatremia without hyperkalemia or normal serum electrolyte concentrations. Hemogram features were variable and were not useful in suggesting a diagnosis of hypoadrenocorticism. The results of this study show that normal or mild serum electrolyte changes in a dog with clinical signs compatible with Addison's disease should not exclude this diagnosis from consideration. Definitive diagnosis depends on the demonstration of inadequate adrenocortical response to adrenocorticotropic hormone (ACTH) stimulation.

Iatrogenic Cushing's syndrome and steroid hepatopathy in a cat.

The distinguishing clinical features of Cushing's syndrome in the cat include very friable skin, a high incidence of diabetes mellitus, and the general absence of steroid hepatopathy. This case report describes a nine-year-old, spayed female domestic shorthair with triamcinolone-induced Cushing's syndrome. Unique to this cat were markedly elevated liver enzymes which prompted an expanded clinical evaluation. An ultrasonographic-guided liver biopsy demonstrated diffuse hepatocellular vacuolation that stained periodic acid-Schiff (PAS) positive and was removed subsequently with diastase application, indicating glycogen accumulation. These findings are compatible with the rarely seen syndrome of steroid hepatopathy in the cat.

Severe calcinosis cutis associated with treatment of hypoparathyroidism in a dog.

A 6-month-old, female border collie was referred for evaluation of hypocalcemia, hyperphosphatemia, fever, and painful ventral abdominal skin. She had recently been treated intravenously and subcutaneously (SC) with a diluted 10% calcium gluconate solution. The medical evaluation supported the diagnosis of primary hypoparathyroidism, but the subsequent hospital course was complicated by severe calcinosis cutis, which caused extensive skin necrosis and marked debilitation. This patient illustrates that administration of a calcium gluconate solution SC can be associated with extensive morbidity when administered to hyperphosphatemic patients.
