Assessment of the circulating inflammatory mediator interleukin-8 in dogs with tracheal collapse.

Objective: Tracheal collapse (TC) is an obstructive respiratory disorder in dogs that can affect lifespan and quality of life. Systemic inflammation has been identified in other obstructive airway conditions in dogs and humans. We hypothesized a systemic pro-inflammatory state exists in dogs with TC.

Incidence and characterization of aerophagia in dogs using videofluoroscopic swallow studies.

Background: Aerophagia (ingestion of air), is a functional aerodigestive disorder in people. Criteria for diagnosis of aerophagia in dogs are >1/3 of bolus volume containing air or ingested air resulting in gastric distention (>1/3 of end gastric volume). Aerophagia is highlighted during eating and drinking.

The impact of single-dose trazodone administration on plasma endogenous adrenocorticotropic hormone and serum cortisol concentrations in healthy dogs.

Background: Conditions affecting the hypothalamic-pituitary-adrenal (HPA) axis are common in dogs. Testing the function of the HPA axis includes measurement of endogenous adrenocorticotropic hormone (eACTH) and performance of an adrenocorticotropic hormone (ACTH) stimulation test. Trazodone is commonly administered to dogs to decrease stress.

Evaluation of infrared thermography and 6-minute walk tests to assess airflow limitation, impaired thermoregulation, and exercise intolerance in dogs with brachycephalic obstructive airway syndrome.

Brachycephalic obstructive airway syndrome (BOAS) is associated with significant morbidity and mortality. Routine clinical evaluation fails to detect physiologic consequences of BOAS including airflow limitation, exercise intolerance, and impaired thermoregulation. A six-minute walk test (6MWT) with infrared thermography (IRT) may aid detection and clinical management by assessing the physiologic consequences of BOAS.

A One Health review of aerodigestive disease in dogs.

This review article seeks to define and describe aerodigestive disease in dogs, and review current and emerging methods of diagnostic evaluation. Aspiration of gastric contents into the respiratory tract is associated with the development and progression of numerous respiratory diseases in humans. In veterinary medicine the term "aspiration" is considered synonymous with "aspiration pneumonia" which, while frequently encountered, does not accurately reflect the breadth of aspiration associated respiratory syndromes (AARS).
