Leucoencephalomyelopathy in Australian Rottweiler dogs.

Clinical and pathological studies of a neurological disorder of 3 adult Rottweiler dogs are described. Dogs developed proprioceptive losses involving the limbs, leading to progressively worsening ataxia and hypermetria. Blood and CSF fluid analyses were normal and radiographs and myelograms showed no compressive lesions of the spinal cord. At necropsy, severe demyelination of the dorsal and lateral funiculi of the cervical spinal cord was visible grossly. Microscopically there was more extensive, symmetrical involvement of the spinal cord and brain than was apparent grossly, with demyelination of white matter tracts and sparing of axons in affected areas. These changes were considered diagnostic for leucoencephalomyelopathy. This condition has not been previously reported in Australia, and is probably transmitted genetically, presumably as an autosomal recessive trait.

Bicipital bursitis in a mare.

A case of bicipital bursitis in a six-year-old mare is described. The horse was presented with acute lameness, pyrexia and hot swelling over the right shoulder region. Although antibiotic treatment relieved these signs, a firm cold swelling remained which had to be removed by surgical resection and drainage.

Suppurative pericarditis treated by pericardiotomy in a cow.

The successful treatment of a single case of traumatic reticulopericarditis is described. Under general anaesthesia the pericardial sac was approached by resection of the distal part of the fifth rib and allowed to drain directly to the exterior. The discussion reviews the surgical technique.

Surgical repair of femoral neck fractures in two dogs and a calf.

The surgical techniques employed in the repair of femoral neck fractures in two dogs and a Charolais calf are described. All the fractures were extracapsular; one of the dogs also had a fractured femoral diaphysis. For both dogs, exposure of the femoral neck was made from a dorsal approach after removal of the greater trochanter, while for the calf, a gluteal transection technique was used. All the fractures were successfully fixed using cortical screws, and in the case of the femoral diaphysis, a vitallium plate was used. All the animals were walking with minimal lameness eight weeks after surgery.

Cervical vertebral instability (wobbler syndrome) in the dog.

Observations on a series of 38 cases (35 Doberman Pinschers and three Great Danes) of the canine wobbler syndrome are described. Radiographic examinations suggested that the primary lesion is an intervertebral instability at C6/7, but with time, secondary changes of the disc degeneration and prolapse and vertebral body malformation causing stenosis of the vertebral canal occur. Cases detected at a young age and showing only the primary lesion were treated successfully, by disc fenestration alone or by disc fenestration and intervertebral screwing. The success rate in older cases with secondary lesions was poor and in this type of case, cord decompression by dorsal laminectomy appears necessary.

Atresia of the nasolacrimal orifice in two thoroughbreds.

Two cases of bilateral atresia of the nasolacrimal orifice are described. The presenting sign was a persistent ocular discharge, clear in the one case and purulent in the other. Treatment by the creation of a fistula between the distal extremity of the blind ending duct and the nasal cavity was successful in both cases.

Surgical repair of cleft soft palate in the horse.

A technique for the surgical repair of a cleft soft palate in the horse is described. A symphysiotomy approach was employed to repair the anterior end of the cleft palate, and the posterior part was approached via a pharyingotomy incision.

Cervical vertebral instability (wobbler syndrome) in the Doberman.

Observations based on the case histories of 39 dogs and bitches (38 Dobermans and 1 Great Dane) diagnosed as "wobblers" are presented. Cases diagnosed at a young age were shown to have cervical vertebral instability particularly at the C6/C7 articulation. Older animals showed a variety of secondary degenerative lesions. Treatment by fenestration of intervertebral disc was effective in cases which showed only vertebral instability but was much less effective in older animals with associated degenerative changes.

Chronic tenosynovitis of the extensor tendons and tendon sheaths of the carpal region in the horse.

Seven cases of chronic tenosynovitis affecting the extensor carpi radialis or lateral digital extensor tendon and their sheaths are described. All cases were chronic and in 4 of the cases previous treatment by drainage and local corticosteroid injection had been ineffective. Surgical exploration of 6 cases demonstrated a distinct lesion and specific surgical treatment was carried out.
