ABSTRACT
A 2-yr old Springhaas (Pedetes capensis; Pedetidae, Rodentia) imported into the USA from the Republic of South Africa was severely debilitated as the result of abberant migrations of adult Filaria versterae (Filarioidea: Filariidae) normally confined to the subcutaneous tissues of this host in Africa. Some nematodes invaded the peritoneal and thoracic cavities, the pericardial sac and the lungs. Invasion of the lungs resulted in life-threatening respiratory distress necessitating euthanasia. Filaria versterae is redescribed.

A 13-month-old German shepherd dog was presented with acute onset of anorexia, pyrexia, lymphadenopathy, and tonsillitis. Tularemia was diagnosed based on a greater-than-fourfold increase in antiFrancisella tularensis antibody titers over a three-week period. The disease was self-limiting, and clinical signs resolved within five days with only supportive therapy.

A 10-year-old cat with restlessness, vocalizing, and circling was examined 13 hours after it was inadvertently given a 5-mg tablet of the CNS stimulant methylphenidate hydrochloride. Physical examination findings (generalized tremors, agitation, mydriasis, tachycardia, tachypnea, and hypertension) were consistent with overstimulation of the CNS and excessive adrenergic activity resulting from methylphenidate toxicosis. Plasma methylphenidate concentration at admission (83 ng/ml) was 5 to 16 times greater than the concentration reported to provide therapeutic effect in human beings. The cat was placed in a dark, padded cage to minimize external stimuli, and supportive care consisting of fluids and diazepam were administered. Clinical signs resolved within 25 hours after ingestion of methylphenidate.

Two mixed-breed cats were examined for intermittent vomiting of several months' duration. Adult Physaloptera preputialis nematodes were detected in the vomitus and melena was observed in both cases. Clinicopathological abnormalities including anemia and eosinophilia were found in one case. Clinical signs resolved following anthelmintic therapy with ivermectin (200 micrograms/kg body weight) administered subcutaneously.

A 2-year-old Collie-type dog with lethargy, tachycardia, tachypnea, and muscle tremors was examined 10 hours after the dog had bitten into an inhalation canister containing the beta 2-adrenergic agonist, terbutaline sulfate. Electrocardiographic findings (ventricular premature contractions and paroxysmal ventricular tachycardia) were consistent with excessive adrenergic activity resulting from terbutaline toxicosis. Serum terbutaline concentration was similar to that reported in human beings with terbutaline toxicosis. The dog did not respond to initial treatment with fluids and lidocaine administered IV, but rapid resolution of signs and conversion to normal sinus rhythm was achieved after IV infusion of propranolol.
