Case ReportsHepatic necrosis following halothane anesthesia in goats.
One goat anesthetized with thiamylal sodium, xylazine, and halothane for repair of an abominal hernia, and 7 of 29 goats similarly anesthetized for an experiment unrelated to considerations of anesthesia, developed signs of hepatic failure within 24 hours of anesthesia. Affected goats had high values for serum aspartate transaminase and serum total bilirubin by 12 to 24 hours after induction of anesthesia. Necropsy of the 8 affected goats revealed centrilobular to massive hepatic necrosis (8 of 8), brain lesions consistent with hepatic encephalopathy (3 of 4), and acute renal tubular necrosis (6 of 6). ⋯ Causes of hepatic necrosis other than those related to anesthesia (eg, infectious agents, toxins) were ruled out by lack of supporting necropsy findings or were considered unlikely because of lack of opportunity for exposure. Hepatic lesions in these goats closely resembled those described in human beings with halothane-associated hepatic injury, although in both species these lesions are nonspecific at the gross and light microscopic levels. The pathogenesis of halothane-associated hepatic injury in goats, as in human beings, remains to be determined.

Comparative StudyResponses of atopic dogs to regional allergens: 268 cases (1981-1984).
Responses of atopic dogs to intradermal challenge with 60 allergens were determined and compared for 4 regions of the United States Twenty-seven allergens incited significantly higher responses in atopic dogs residing in northern Florida, when compared with dogs in Illinois; responses to 28 allergens were more significant in dogs residing in southern Florida vs Illinois. Only 1 allergen caused more responses in atopic dogs in northern Florida, compared with dogs in southern Florida. ⋯ Dogs of the Poodle, Pug, German Shepherd Dog, Cocker Spaniel, Bulldog, Schnauzer, Doberman Pinscher breeds, of mixed breeding, and of terrier breeds other than the 2 aforementioned were not found to have a higher prevalence, when compared with the general hospital population. Of the atopic dogs evaluated in Florida, 79% had a significant response to flea antigen, compared with only 9% of atopic dogs evaluated in Illinois.
