External Radiation Dose to Owners of Canines Treated with ( 117m Sn) Radiosynoviorthesis for Osteoarthritis.

A novel device in the veterinary market uses a colloid containing radioactive 117m Sn to treat osteoarthritis in the synovial joints of canines. The technique of injecting a radioisotope to restore synovia is referred to as radiosynoviorthesis. The outpatient canine procedure uses a maximum administration of 222 MBq of 117m Sn injected into one or more joints.

Use of magnetic resonance imaging-guided biopsy of a vertebral body mass to diagnose osteosarcoma in a Rottweiler.

CASE DESCRIPTION A 9-year-old spayed female Rottweiler with hind limb ataxia was examined because of anorexia and an acute onset of hind limb paresis. CLINICAL FINDINGS Neurologic evaluation revealed hind limb ataxia and symmetric paraparesis with bilaterally abnormal hind limb postural reactions including hopping, hemiwalking, hemistanding, and delayed proprioception, which were suggestive of a lesion somewhere in the T3-L3 segment of the spinal cord. Thoracolumbar radiography revealed an abnormal radiopacity suggestive of a mass at T11.

Influence of ketamine on the cardiopulmonary effects of intramuscular administration of dexmedetomidine-buprenorphine with subsequent reversal with atipamezole in dogs.

Objective: To compare the cardiorespiratory effects of IM administration of dexmedetomidine-buprenorphine (DB) and dexmedetomidine-buprenorphine-ketamine (DBK) in dogs with subsequent reversal with atipamezole.

Design: Prospective, randomized crossover study.

Animals: 5 healthy dogs.

Evaluation of anesthetic, analgesic, and cardiorespiratory effects in dogs after intramuscular administration of dexmedetomidine-butorphanol-tiletamine-zolazepam or dexmedetomidine-tramadol-ketamine drug combinations.

Objective: To compare anesthetic, analgesic, and cardiorespiratory effects in dogs after IM administration of dexmedetomidine (7.5 μg/kg)-butorphanol (0.15 mg/kg)-tiletamine-zolazepam (3.

Hemodynamic effects in dogs after intramuscular administration of a combination of dexmedetomidine-butorphanol-tiletamine-zolazepam or dexmedetomidine-butorphanol-ketamine.

Objective: To evaluate hemodynamic effects in dogs after IM administration of dexmedetomidine (7.5 μg/kg, butorphanol (0.15 mg/kg), and tiletamine-zolazepam (3 mg/kg [DBTZ]) or dexmedetomidine (15 μg/kg), butorphanol (0.

Evaluation of dexmedetomidine and ketamine in combination with various opioids as injectable anesthetic combinations for castration in cats.

Objective: To compare the efficacy and cardiorespiratory effects of dexmedetomidine-ketamine in combination with butorphanol, hydromorphone, or buprenorphine with or without reversal by atipamezole in cats undergoing castration.

Design: Prospective, randomized, split-plot, blinded study.

Animals: 30 healthy male cats.
