RESUMEN
A 13-year-old female spayed domestic shorthair cat presented for investigation of decreased appetite and increased serum liver enzyme concentrations. An abdominal ultrasound revealed multiple sessile hyperechoic structures along the luminal aspect of the gall bladder wall and a mildly enlarged liver with hyperechoic nodules. Cholecystectomy was performed and biopsies were obtained by laparotomy. Histopathologic examination with immunohistochemistry was consistent with a diagnosis of small-cell lymphoma of T cells within the gall bladder, liver and small intestine. Clonality testing confirmed the diagnosis. The cat remains clinically stable 23 months after institution of treatment with prednisolone, chlorambucil and ursodeoxycholic acid. This is the first report of small-cell lymphoma in the gall bladder of a cat.

The effects of diazepam or lidocaine on the propofol induction dose and certain cardiovascular parameters were documented in this randomized, blinded study. Dogs received 0.9% saline (0.1 mL/kg intravenously [i.v.]), lidocaine (2 mg/kg i.v.), or diazepam (0.25 mg/kg i.v.) prior to propofol i.v. until loss of jaw tone was achieved (up to a maximum of 8 mg/kg). Propofol was followed by 0.3 mg/kg atracurium i.v. Direct arterial blood pressures and heart rates were recorded before premedication, induction, and intubation. No statistically significant differences were found among the groups for cardiovascular measurements or for the propofol dose required for intubation.
