Abstract

Hypoadrenocorticism is characterized by a reduction in mineralocorticoid and/or glucocorticoid production by the adrenal glands. Several subtypes have been described with different clinical and clinicopathological consequences. Most affected dogs have vague and non-specific signs that precede an eventual life-threatening crisis. This review aims to appraise classification, the available data on epidemiology and the clinical and laboratory features of naturally occurring canine hypoadrenocorticism.

PubMed Other Abstract

Canine hypoadrenocorticism is a relatively uncommon endocrine disease that can present with a wide variety of clinical signs resulting from cortisol or aldosterone deficiency or both. Hypoadrenocorticism should be considered in all dogs with severe illness and typical electrolyte abnormalities but also in those with waxing and waning clinical signs. Multiple clinical and laboratory features are suggestive of the disease and should prompt evaluation of adrenal function. The ACTH stimulation test is the best test for diagnosing hypoadrenocorticism but, in those cases without the typical presentation, evaluation of aldosterone secretory capacity and endogenous ACTH concentrations should be performed to distinguish primary from secondary disease. In this review we discuss the pathophysiology of the disease, the clinical signs and laboratory features that should raise suspicion of hypoadrenocorticism and the performance of the different diagnostic tests.

Toxocara cati Infection in Cats
The Companion Animal Parasite Council recommends testing kittens for intestinal parasites at least 4 times in the first year of life and twice a year thereafter. Although the prepatent period for T cati infection is 8 weeks, to combat any potential of hookworm infection, treatment for parasitic infection should be initiated at 2 weeks of age and repeated every 2 weeks until regular broad-spectrum parasite control is begun.

In all species, the most frequent neoplasms were squamous cell carcinomas in ruminants, while melanoma was the most frequent in swine.
Endoscope-Guided Marble Foreign Body Removal Technique in an Inland Bearded Dragon (Pogona vitticeps)
The marble foreign body was suctioned and removed orally using a red rubber catheter and a Luer-lock syringe. This report provides a novel, nonsurgical method for removing smooth spherical foreign bodies from the proximal gastrointestinal tract of bearded dragons. The technique may apply to various small-to-medium–sized reptiles or amphibians that present with spherical foreign bodies.
Treatment and outcome following substantial ketamine overdose in a dog.
This case report documents an iatrogenic 338 times intravenous ketamine overdose in a dog, which was successfully managed with supportive care. In addition, it highlights the importance of doctor-technician communication and the potential errors in using electronic treatment sheets.
