Remission of diabetes mellitus after ovariohysterectomy in a guinea pig with ovarian cysts.

A 3-year-old intact female guinea pig was presented with a history of polydipsia, polyphagia, and hyperactivity combined with non-pruritic hair loss. The physical examination revealed bilateral alopecia mainly including the flanks and the ventral abdomen. Bilateral rounded masses just caudal to the kidneys were detected on abdominal palpation.

Thymomas in rabbits: clinical evaluation, diagnosis, and treatment.

Thymomas are rarely recorded in rabbits, and the literature includes comparatively few cases. Medical records were reviewed to identify all pet rabbits in which a mediastinal mass was diagnosed between Feb 2007 and Jan 2010. Signalment, history, clinical signs, diagnostic work-up (including laboratory data, diagnostic imaging, and ultrasound-guided fine-needle aspiration of the mediastinal mass), treatment modalities, survival time, and histologic findings were evaluated.

Airway hyperresponsiveness to adenosine 5'-monophosphate in feline chronic inflammatory lower airway disease.

Airway hyperresponsiveness is a key feature of human asthma and chronic bronchitis and response to the indirectly acting agonist adenosine 5'-monophosphate (AMP) is thought to reflect underlying airway inflammation. To examine whether airway responsiveness testing (ART) with AMP may be used to differentiate healthy cats from those with asthma (FA) and chronic bronchitis (CB), 24 cats (9 FA, 6 CB, 9 controls) underwent ART with AMP at concentrations of 0.1, 1, 10, 100 and 500mg/mL using barometric whole body plethysmography.
