Case Description—2 cats (13 and 11 years old) were evaluated to determine the cause of nasal discharge of varying duration (4 days and 5 months, respectively).
Clinical Findings—Computed tomography revealed marked turbinate destruction and soft tissue densities in the nasal passages. Histologic examination of nasal specimens revealed chronic active inflammation and branching fungal hyphae consistent with Aspergillus spp. Fungal culture of nasal specimens resulted in growth of Aspergillus spp. Testing yielded negative results for antibodies against Aspergillus spp.
Treatment and Outcome—Both cats were anesthetized and treated with a 1-hour intranasal infusion of clotrimazole. Recovery from the procedure was uncomplicated, and both cats had complete resolution of clinical signs.
Clinical Relevance—Little information is available on the treatment of nasal aspergillosis in cats, and the prognosis for affected animals is considered poor. The procedure for local intranasal infusion of clotrimazole in 2 cats was described here. Results and follow-up monitoring for both cats suggested that this may be a safe, effective, and durable treatment for cats with nasal aspergillosis.
Objective—To evaluate pituitary-adrenal function in critically ill dogs with sepsis, severe trauma, and gastric dilatation-volvulus (GDV).
Animals—31 ill dogs admitted to an intensive care unit (ICU) at Washington State University or the University of Pennsylvania; all dogs had acute critical illness for < 48 hours prior to admission.
Procedures—Baseline and ACTH-stimulated serum cortisol concentrations and baseline plasma ACTH concentrations were assayed for each dog within 24 hours after admission to the ICU. The change in cortisol concentrations (Δ-cortisol) was calculated for each dog. Morbidity and mortality data were recorded for each patient.
Results—Overall, 17 of 31 (55%) acutely critically ill dogs had at least 1 biochemical abnormality suggestive of adrenal gland or pituitary gland insufficiency. Only 1 (3%) dog had an exaggerated response to ACTH stimulation. Dogs with Δ-cortisol ≤ 83 nmol/L were 5.7 times as likely to be receiving vasopressors as were dogs with Δ-cortisol > 83 nmol/L. No differences were detected among dogs with sepsis, severe trauma, or GDV with respect to mean baseline and ACTH-stimulated serum cortisol concentrations, Δ-cortisol, and baseline plasma ACTH concentrations.
Conclusions and Clinical Relevance—Biochemical abnormalities of the hypothalamic-pituitary-adrenal axis indicative of adrenal gland or pituitary gland insufficiency were common in critically ill dogs, whereas exaggerated responses to ACTH administration were uncommon. Acutely ill dogs with Δ-cortisol ≤ 83 nmol/L may be more likely to require vasopressors as part of the treatment plan.
