Ultrasonography and radiography were used to diagnose bicipital tenosynovitis and humeral osteitis in a horse with a history of lameness of 7 weeks' duration. Surgical exploration confirmed the diagnosis.

Polyostotic hyperostosis associated with oviductal tumor in a cockatiel.

A 10-year-old female cockatiel in a thin and depressed condition and with a 1 X 2-cm soft abdominal swelling was hospitalized. Radiography revealed a well-circumscribed mass containing punctate areas of mineralization, displacing the gizzard cranially in the caudodorsal portion of the abdomen. There was bilateral, symmetric, generalized, increased medullary opacity of the radius, ulna, carpometacarpus, femur, tibiotarsus, and tarsometatarsus. These findings were compatible with polyostotic hyperostosis secondary to an estrogen-secreting tumor. Euthanasia and necropsy were requested. A small area of neoplastic cells in the oviduct was identified histologically, but most of the tissue mass consisted of necrotic cellular debris. There was no metastasis. Sagittal secretions of decalcified radiopaque bones revealed up to 60% filling of medullary cavities with bone spicules. Although clinical and radiographic findings were compatible with an estrogen-secreting tumor, osteopetrosis, metastatic neoplasia, hypertrophic osteopathy, and metabolic bone disease were included in the initial differential diagnosis. The absence of metastasis and the confinement of the tumor within the oviduct would have made surgical removal a possible approach to treatment.

Analysis of binding of a technetium-99m-labeled monoclonal antibody to lentivirus-infected cells.

Caprine arthritis-encephalitis (CAE) is a model for the study of lentiviral infections. The authors' hypothesis is that radioimmunodetection has the potential to detect lentiviral proteins at the surface of infected cells. A monoclonal antibody (CAEV92A1) specific for a CAE virus (CAEV)-associated glycoprotein and a control antibody were radiolabeled with technetium-99m (99mTc) using the pretinning method. Cell binding assays were used to evaluate immunoreactivity and binding properties of 99mTc-labeled antibodies to CAEV-infected cells. 99mTc-CAEV92A1 bound preferentially to paraformaldehyde-fixed and live CAEV-infected cells. 99mTc-CAEV92A1 did not appear to be shed rapidly from its binding site.

The use of megestrol acetate in some feline dermatological problems.

Twenty-one cats were treated with megestrol acetate because they were showing clinical signs associated with one of the following problems: eosinophilic ulcer, eosinophilic plaque, neurodermatitis, endocrine alopecia and miliary dermatitis. The dosage schedule was 5 mg orally per day per cat for seven days, then 5 mg every three days for 21 days. In all cats, we noted a good improvement of the lesions as soon as treatment was started. In 25% of the patients, one treatment schedule was sufficient to control the skin disease for at least 18 months. In the remaining 75%, two treatment schedules and/or a maintenance dosage had to be established.Side effects encountered were increased appetite, personality changes and depression.
