Top Endocrine Publications of 2012: The Canine Adrenal Gland

In my seventh compilation of the canine and feline endocrine publications of 2012, I’m moving on to disorders of the canine adrenal gland.

Listed below are 40 research papers written in 2012 that deal with a variety of adrenal gland issues of clinical importance in dogs. I've already reviewed 4 of these papers; to read my reviews, see the links at the bottom of the reference list.

These range from the investigations of trilostane and dosing (1,11,35) or its effect on steroid hormone metabolism in adrenal glands and corpora lutea (32) to a study of an evaluation of compounded trilostane (6); from investigations of the sudden acute blindness that can develop in dogs with pituitary-dependent hyperadrenocorticism (PDH) (3,4) to the vitamin-D status in dogs with PDH (7); and from studies of the effect of cortisol excess (Cushing's syndrome) on renal function (37-39) to the use of low-dose insulin administration to prevent the onset on overt diabetes in dogs with PDH (27).

Other research studies included a review of the animal models of adrenocortical tumorigenesis (2) to a review of diagnostic tests for Cushing's syndrome (21); from studies to compare IV and IM formulations of ACTH in dogs (5) to ultrasound studies of the adrenal gland in normal dogs, dogs treated with steroids, or dogs with adrenal tumor (8,9,33); from reports of adrenalectomy for treatment of dogs with adrenal tumor causing  hyperaldosteronism (12,15), or pheochromocytoma (17); and finally, from studies of the relationship between gallbladder mucoceles and glucocorticoid excess (22) to a number of studies of the effects of exogenous glucocorticoids and iatrogenic Cushing's syndrome in dogs (18,20,22-24,26,31,33,40)
