Serum cardiac troponin I concentrations in dogs with generalised seizures.

Objectives: To determine if serum cardiac troponin I concentrations - measured with both a first-generation assay and a high-sensitivity assay - were greater in dogs with generalised seizures than in controls and to identify clinical variables associated with cardiac troponin I concentration.

Materials And Methods: Prospective study of 30 dogs with recent generalised seizures and 30 healthy controls. Serum cardiac troponin I concentration was measured using two commercially available assays, and the correlation of clinical factors with concentration was examined.

Papillary tumor of the pineal region of a dog.

A 3-year-old, intact, male Beagle dog developed clinical signs of pleurothotonus and altered head position to the right, neck pain, nystagmus, hyperreflexia of the left forelimb, and hyperextension of both forelimbs. Magnetic resonance imaging enabled a tentative diagnosis of thalamic neoplasia with incidental hydromyelia at the level of the second cervical vertebra. The animal was euthanatized due to the poor prognosis, and a necropsy was performed.

Magnetic resonance imaging of feline hippocampal necrosis.

The clinical, neuropathologic, and magnetic resonance (MR) imaging features in four cats with necrosis of the hippocampus and piriform lobe are described. All cats had acute generalized seizures and behavioral changes including aggression, salivation, polyphagia, and disorientation. Routine hematologic, serum chemistry, and cerebrospinal fluid analyses were normal.

[Sacral osteochondrosis dissecans in a Bernese Mountain Dog: diagnosis and treatment].

A 18-month-old female Bernese Mountain Dog with chronic pain at jumping, extension of the right hind leg and paresis of the tail was referred to the Neurological Service of the Veterinary Hospital of the University of Zurich. Upon radiological examination a mineralised fragment at the dorsal aspect of the endplate of S1 was detected. The diagnosis of Osteochondrosis dissecans was confirmed by linear and computed tomography as well as histologic examination of the fragment, which was surgically removed.

Healing of dorsal pancarpal arthrodesis in the dog.

The purpose of this study was to assess radiographically the healing process in dogs which had undergone dorsal pancarpal arthrodesis with autologous cancellous bone grafting. The medical records of 17 dogs that had undergone dorsal pancarpal arthrodesis with complication-free dynamic compression plate fixation were reviewed. Postoperative healing was evaluated radiographically.

Some recent pharmacological findings with nitrendipine.

The available evidence indicates that nitrendipine and other dihydropyridines with a similar pharmacological action exert their therapeutic effects by inhibiting Ca2+ channels. In our recent experiments, nitrendipine was shown to block K+-stimulated 45Ca2+ uptake and K+-induced contractions of isolated rabbit aortic rings. Its IC50 were 4.
