A review of portal screen-film technology and five radiologists' evaluations of some existing products.

Portal radiographs, radiographs made to document the accuracy of radiotherapy treatment fields, are typically of poor image contrast. Recently, a new portal film and screened-cassette system was marketed, the Kodak EC-L system, with the claim of greatly improved image contrast. This new EC-L system was tested on a canine cadaver exposed to Cobalt-60 teletherapy gamma radiation, and image quality was compared to earlier marketed Kodak portal film products.

New form of X-linked dominant hereditary nephritis in dogs.

Objective: To determine features of a new form of hereditary nephritis (HN) in dogs.

Animals: Parents and 16 first-generation offspring (8 males, 8 females).

Procedure: Adolescent dogs that developed renal failure were euthanatized and necropsied.

A model of autosomal recessive Alport syndrome in English cocker spaniel dogs.

Background: Dogs with naturally occurring genetic disorders of basement membrane (type IV) collagen may serve as animal models of Alport syndrome.

Methods: An autosomal recessive form of progressive hereditary nephritis (HN) was studied in 10 affected, 3 obligate carrier, and 4 unaffected English cocker spaniel (ECS) dogs. Clinical, pathological, and ultrastructural features of the disease were characterized.

Disseminated coccidioidomycosis in a mandrill baboon (Mandrillus sphinx): a case report.

A case of disseminated coccidioidomycosis caused by a dimorphic fungus Coccidioides immitis in a mandrill baboon (Mandrillus sphinx) was diagnosed following radiography, ultrasound-guided aspiration of thoracic lesions, and aspiration cytology of skeletal lesions of the left sixth rib. The diagnosis was confirmed by fungal culture and serum quantitative immunodiffusion for antibodies against C. immitis.

Early diagnosis of familial nephropathy in English cocker spaniels.

Two litters of English cocker spaniels (ECSs) produced by familial nephropathy (FN) carriers were evaluated to characterize the early features of this disease. Three puppies developed FN. Proteinuria, which began when these puppies were five-to-eight months old, was the first abnormality detected.
