RESUMO
Chronic recurrent multifocal osteomyelitis is a rare inflammatory bone disease of children and adolescents that is characterized by localized swelling and pain in the clavicles and long bones of the limbs. Diagnosis of chronic recurrent multifocal osteomyelitis is made from clinical signs, characteristic radiographic and histopathologic findings, and negative results of microbial cultures. Treatment of chronic recurrent multifocal osteomyelitis in humans includes administration of nonsteroidal anti-inflammatory drugs or immune modulators, which may be effective in lemurs.

A 16-year-old, neutered male, domestic short hair cat had abdominal distension and systemic hypertension. Radiography, ultrasonography, excretory urography, and renal scintigraphy were performed to establish the diagnosis and implement appropriate treatment. Bilateral perirenal pseudocysts were confirmed surgically and histopathologically. Following bilateral renal capsulectomy, systemic hypertension decreased and global glomerular filtration rate improved to normal limits. Multiple imaging modalities helped establish the diagnosis and guided implementation of appropriate treatment.

The effects of radioulnar fixation were studied in 21 Quarter horse foals by applying a bone plate to the caudal aspect of the proximal part of the ulna, with screws engaging both the radius and the ulna. The plates were applied at 1 month of age in six foals (group I), 5 months of age in six foals (group II), and 7 months of age in three foals (group III). Six foals underwent sham operations at 1 month of age to serve as controls (group IV). Ulnar dysplasia and elbow subluxation developed in all treated foals. The magnitude of ulnar dysplasia was inversely related to the patient's age at fixation and was accompanied by degenerative joint disease and lameness in foals undergoing fixation at 1 and 5 months of age. Removal of the fixation appliances 16 weeks after implantation in three foals from each of groups I and II failed to reverse the degree of ulnar dysplasia. Although foals undergoing fixation at 7 months of age (group III) were not lame, radiographic evidence of subluxation and subtle degenerative changes in the articular cartilage of the treated elbow did develop. Recommendations for avoidance of radioulnar fixation were developed from these observations.

This is a report of two dogs in which osteosarcomas arose in association with metallic orthopedic implants. One neoplasm occurred in the distal humerus of a 12-year-old Doberman Pinscher. A stainless steel intramedullary pin had been implanted in the bone 11 years previously. Upon removal, corrosion of the pin was noted. The second neoplasm arose in the proximal tibia of a 12-year-old Irish Wolfhound. Six years previously, a fracture of the tibia had been repaired with a plate and screws made of the same type stainless steel, type 316L, by the same manufacturer. No corrosion appeared to have occured. Infection had not occured in either animal.
