Feline aortic thromboembolism

Aortic thromboembolism is one of the most serious and difficult-to-manage complications. of feline cardiac disease. Most, but not all, cats presenting with signs of aortic thromboembolism are found to have underlying cardiac disease at the time of presentation. In most cases no underlying disease has been diagnosed prior to presentation with paresis/paralysis and profound anxiety. This article will review commonly used treatments for thromboembolism and agents proposed for prophylaxis. Many of the proposed treatments are themselves associated with a high morbidity rate and long term clinical trials are required to make comparative risk-to-benefit ratio assessments of these different options. In cats which do survive the initial treatment, clinicians are still faced with the perplexing problem of long term thrombus prevention, as a majority of cats have been shown to re-embolise despite prophylaxis.

Repair of three pathologic fractures in a dog with multiple myeloma

Three pathological fractures occurred secondary to osteolytic lesions of multiple myeloma. Two long bone fractures were each stabilised using interlocking nail fixation augmented with polymethyl meth acral ate bone cement. One vertebral fracture was stabilised using Steinmann pins and PMMA. Successful stabilisation, rapid return to function and improvement in quality of life occurred in all fractures. The patient survived approximately eight months on concurrent chemotherapy.

The medicine and epidemiology of bovine respiratory disease in feedlots

Bovine Respiratory Disease (BRD) results from a complex, multifactorial interaction of stressors, animal susceptibility, and respiratory pathogens. The infectious agents associated with BRD are ubiquitous among cattle populations. Typically, one or a combination of stressors are necessary to initiate BRD. Prevention of BRD should, therefore, address management procedures to minimise stressors. Administration of vaccines against BRD agents may help reduce the incidence of BRD but is unlikely to eliminate the condition. The effectiveness of antimicrobials in the treatment of BIRD depends primarily on early recognition and treatment. The use of antioxidant vitamins, minerals or other agents in the prevention and treatment of BRD warrants further research.

The effects of peripheral and central warming on body temperature during canine laparotomy

Actively warming patients during surgery is considered the best method of preventing inadvertent hypothermia due to multiple causes: anaesthetic depression of the hypothalamic thermoregulatory centre, cutaneous vasodilatation, reduction of heat production by skeletal muscles, cold intravenous fluid administration and heat loss from opened body cavities. To compare the effects of active peripheral skin warming and trunk warming on body temperature during surgery, 15 dogs undergoing ovariohysterectomy were studied using a prospective randomised trial design. Dogs were randomised into two groups: one group was warmed by compress leg pads (n=7) on limbs and the other group by a circulating warm water mattress (n=8), applied to the trunk. The rectal, oesophageal and room temperatures and relative humidity were measured. The results showed that the compress leg pads (active peripheral warming) were significantly (P

Inverted canines in the Staffordshire Bull Terrier - a new clinical condition

A condition is described where the mandibular canine teeth of Staffordshire Bull Terriers are tipped (curved) caudally and impact at the mesio-palatal gingival margin of the maxillary canine teeth. The aetiology of the condition and possible treatment options are discussed.

Control of familial and renal cardiac diseases in English bull terriers: How to repair a damaged breed?

Control recommendations are presented for four genetic or familial diseases that cause significant morbidity and mortality in affected English Bull Terriers. Bull Terrier polycystic kidney disease is an autosomal dominant disease diagnosed by detecting a minimum of three renal cysts, with cysts present in both kidneys, and similarly affected family members to confirm the inherited nature of the cysts. Bull Terrier hereditary nephritis is an autosomal dominant disease diagnosed in otherwise normal animals with urinary protein: creatinine ratios persistently >0.3 and no significant urinary sediment, a family history of the disease, and characteristic glomerular basement membrane lesions. Mitral valve myxomatous degeneration and left ventricular outflow tract obstruction in Bull Terriers are familial diseases diagnosed by auscultating characteristic murmurs in affected animals. Excluding animals with these clinical signs from the breeding pool will reduce the prevalence rates of these diseases, however maintenance of an effective population size is also important. Providing breeders with information on genetics, including the risks associated with inbreeding and the benefits of outcrossing, is likely to improve canine breeding practices, thus increasing fitness and fecundity of these purebred dogs.

Intra-abdominal lipoma in a dog

A 13-year-old Labrador cross dog was presented with progressive abdominal distension of three to four months duration. A large abdominal mass displacing the intestines in a cranio-dorsal direction was diagnosed radiographically. A 4.5kg intra-abdominal lipoma was surgically removed from the lesser omentum near the splenic pedicle. This condition has been infrequently reported in the dog.

Lectures and other types of teaching

A questionnaire on lectures was completed by 351 students (84% response) and 35 staff (76% response) from all five years of the veterinary course at the University of Queensland. Staff and students in all five years offered limited support for a reduction in the number of lectures in the course and the majority supported a reduction in the number of lectures in the clinical years. Students in the clinical years only and appropriate staff agreed that the number of lectures in fifth year should be reduced but were divided as to whether lectures in fifth year should be abolished. There was limited support for replacement of some lectures by computer assisted learning (CAL) programs, but strong support for replacement of some lectures by subject-based problem based learning (PBL) and strong support for more self-directed learning by students. Staff and students strongly supported the inclusion of more clinical problem solving in lectures in the clinical years and wanted these lectures to be more interactive. There was little support for lectures in the clinical years to be of the same type as in the preclinical years.
