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. Preoperative imaging allowed a minimal surgical approach using a unilateral, modified dorsal laminectomy. Outcome was evaluated by neurological reevaluation and a CT scan performed 6 months after surgery.

CANINE HIP DYSPLASIA EVALUATION

The ventrodorsal radiograph of the pelvis and femurs with the hind limbs extended, femurs parallel to each other, patellae superimposed over the distal femurs, and the pelvis symmetrical has become the standard method by which to evaluate animals for hip dysplasia. The following illustrated guide details the methods of positioning recommended by the American Veterinary Medical Association¹ and used by the Orthopedic Foundation for Animals (OFA). Additionally, some commonly encountered positioning errors and methods of labeling radiographs are shown. The authors stress positioning requirements and aids they feel are necessary to produce an adequately positioned radiograph.     

Spinal spondylosis and acute intervertebral disc prolapse in a European brown bear (Ursus arctos arctos)

A 22-year-old male European brown bear (Ursus arctos arctos) was presented to the Onderstepoort Veterinary Academic Hospital after an acute onset of hind limb paralysis 4 days earlier. Previous radiographs revealed marked degenerative joint disease of the stifles, tarsi and digits. The clinical findings were consistent with acute disc prolapse. Lateral radiographs of the entire vertebral column were made as well as ventrodorsal pelvic radiographs. The latter were within normal limits. The vertebral column revealed multiple lesions consistent with chronic and acute disc herniations. Lateral compression of the caudal lumbar nerve roots could not be ruled out. Owing to multiple significant findings of the vertebral column and the poor prognosis for full recovery after surgery, the bear was euthanased. The diagnosis of an acute disc prolapse and multiple chronic disc herniations was confirmed on necropsy.     

Paresis secondary to an extradural hematoma in a Sumatran tiger (Panthera tigris sumatrae).

A 15-yr-old female Sumatran tiger (Panthera tigris sumatrae) was presented to the Boren Veterinary Medical Teaching Hospital at Oklahoma State University with a 3-wk history of progressive hind limb weakness. Neurologic evaluation was limited to review of videotape that demonstrated weakness and ataxia with conscious proprioceptive deficits of the tiger's pelvic limbs. Spinal radiography demonstrated disc space narrowing, and myelography demonstrated a large extradural compressive lesion at the level of L2-3. Computed tomography did not reveal bone involvement. Surgery was performed to decompress the spinal cord and obtain a definitive diagnosis. A right hemilaminectomy was performed after a dorsal approach to the lumbar spine. Histologic examination of the mass revealed a consolidated extradural spinal hematoma, presumed to be secondary to intervertebral disc herniation. Despite incomplete resection of the mass and plastic deformation of the spinal cord, the tiger returned to normal ambulation within 3 wk of surgical decompression.     

Diagnosis and Surgical Management of Pythiosis in Draft Horses: Report of 33 Cases in Egypt

A total of 33 draft horses suffering from cutaneous pythiosis were referred to Mansoura Veterinary Teaching Hospital, Egypt, between October 2008 and January 2011. The animals presented ulcerative, granulomatous lesions located at the ventral aspect of the thorax (n = 10), abdomen (n = 14), forelimbs (n = 5), hind limbs (n = 2), and presternal region (n = 1) and at withers (n=1). The animals suffered from ulcerations composed of whitish yellow tissue having numerous draining tracts that discharge serosanguineous or bloody exudates. Initial diagnosis was based on location, gross lesion, and presence of kunkers. Histopathological evaluation revealed an eosinophilic granulomatous reaction associated with intralesional hyphae characteristic of Pythium insidiosum visualized by Gomori methenamine silver stain. The outcome of surgical excision revealed complete cure in 24 cases. Euthanasia was indicated in 9 cases.     

Hip dysplasia in the New Zealand Huntaway and Heading dog

AIMS: To conduct a practice-based survey to obtain, for the first time, data on hip dysplasia in the New Zealand working dog breeds of Huntaway and Heading Dogs. METHODS: A mailed request and personal approaches to farmer clients of Taihape and Waimarino Veterinary Services were used to recruit dog owners from the Taihape district in the North Island of New Zealand. Recruited dogs were radiographed under anaesthesia in a standard position with both hind limbs extended so that the femurs were parallel and rotated medially. The standard scoring system adopted by the New Zealand Veterinary Association (NZVA) Hip Dysplasia Scheme was used to score the hip radiographs of the dogs. RESULTS: Radiographs of the hips of 141 dogs (93 Huntaways; 48 Heading Dogs), were evaluated. The overall prevalence of hip dysplasia (defined as a combined score from both hips of 10) was 17.7%. Prevalences in Huntaways and Heading Dogs were 23.6% and 6.3%, respectively; in this sample of dogs, the odds ratio (and 95% confidence interval) for Huntaways having a score of 10 was 4.6 (1.316.0) that of Heading Dogs. The average scores were 10.8 for Huntaways and 5.9 for Heading Dogs. Huntaways were at the higher end of the breed average scores for dogs recorded in the NZVA Hip Dysplasia Scheme and Heading Dogs at the lower end. CONCLUSIONS: This preliminary study indicates that hip dysplasia may be a problem in the Huntaway breed. Investigation of the epidemiology of the condition in this breed is warranted and consideration should be given to removing high-risk Huntaways from the breeding pool.     

Multiloculated solitary (unicameral) bone cyst in a young dog

A 20‐month‐old female spayed Staffordshire Terrier (22.3 kg) presented to the Orthopedic Surgery Service at North Carolina State University Veterinary Teaching Hospital for evaluation of a 6‐week history of toe‐touching to nonweight‐bearing lameness in the right hind limb. Radiographs of the right stifle revealed a multiloculated lytic lesion of the distal femur, with a large open lytic zone centrally, numerous osseous septations peripherally, and focal areas of cortical thinning and loss. An aspirate of the right distal femoral lesion yielded mildly cloudy serosanguineous fluid. Cytologic examination of the fluid revealed a pleomorphic population of discrete cells that exhibited marked anisocytosis and anisokaryosis and a variable nuclear‐to‐cytoplasmic (N:C) ratio, which were interpreted as probable neoplastic cells, with few macrophages, and evidence of hemorrhage. Given the clinical signs of pain, lesion size, and concern for malignant neoplasia, amputation of the right hind limb was performed. Histologically, the lesion had undulating walls 1‐3 mm thick with a continuous outer layer of dense fibrous tissue and an inner layer composed of reactive cancellous bone with no cortical compacta remaining. Remnants of thin fibrous or fibro‐osseous septa projected from the bony wall into the cyst lumen. The final histologic diagnosis was a benign multiloculated solitary (unicameral) bone cyst of the distal right femur. Based on the histopathologic findings, it was speculated that the cells identified on cytology were a mixture of developing osteoclasts, osteoblasts, endothelial, and stromal cells. This is the first report describing the cytologic examination of a solitary bone cyst in veterinary medicine.     

Tetanus in a Camel (Camelus dromedarius) – A Case Report

Twenty days after an open castration, a 5-year-old dromedary was presented to the Dubai Camel Hospital with severe central nervous symptoms. The dromedary showed the following signs: off feed, stiff gait with extended neck, external swelling of the preputial sheath and groin region, and foamy saliva drooling from the mouth. The dromedary was unable to swallow. Three days after admission, the camel developed lockjaw, and on the fifth day it was unable to stand owing to paralysis of the hindquarters. Because of the severity of the disease and because it did not respond to treatment, the camel was euthanized 26 days after the operation and submitted to the Central Veterinary Research Laboratory for further investigation. Both castration wounds were closed and spermiducts were filled with necrotic masses from which Clostridium tetani was isolated. Two mice, which were injected with the filtrate of the thioglycolate broth, developed typical signs of tetanic spasm of the hind leg. Faecal samples from camel and horse paddocks that were only 50 metres apart were negative for C. tetani. However, C. tetani was isolated from two soil samples of the horse paddock. It is recommended that camels should be vaccinated against tetanus prior to castration.     

Digital extensor tendon lacerations in horses: A retrospective evaluation of 22 cases

Hospital records of 22 horses referred to the Royal Veterinary and Agricultural University (RVAU) of Copenhagen between January 1, 1990 and December 31, 1993 for treatment of digital extensor tendon laations were reviewed, and follow-up information on final outcome was collected to determine whether any injury or treatment factors could be associated with the outcome.

Mean age of the horses was 5.2 years (range, 1 to 20 years), and follow-up time ranged from 1 to 5 years after injury. In 21 (95%) of the horses, injury involved the hind limbs. Eleven (50%) horses returned to their original or intended level of use. Eighteen (82%) horses had no signs of lameness. There was no statistically significant correlation between outcome and elapsed time from injury to treatment, type of injury, treatment variables, or wound healing in the present study, and these findings support previous reports.

It was concluded that horses with digital extensor tendon lacerations had a favorable prognosis for return to riding soundness and a fair prognosis for return to their original or intended level of use. Tendon suturing and primary wound healing did not improve the prognosis.     

Extracutaneous neutrophilic inflammation in a dog with lesions resembling Sweet's Syndrome

A 7-year-old-spayed female standard poodle dog presented to the Iowa State University Veterinary Teaching Hospital with an 8-day history of lethargy, left hind limb lameness, ptyalism and peripheral lymphadenomegaly. On physical examination, the dog was lethargic, febrile (40.5 °C) and had multifocal to coalescing erythematous papular to pustular eruptions on the skin of all four limbs, periocularly and on the ventral and lateral thorax and abdomen. Histopathological findings from skin biopsies of the papules revealed a severe diffuse neutrophilic dermatitis with sub- and intra-epithelial pustules. Four days after being admitted the dog died from cardiac and respiratory failure. At necropsy, in addition to the multifocal to coalescing erythematous papules, the skin contained scattered pustules. Additionally, the subcutaneous tissue surrounding the right stifle was diffusely oedematous, and the peripheral and visceral lymph nodes were enlarged. The predominant histologic lesion was neutrophilic inflammation, in the absence of detectable bacteria in the skin, heart, lungs, oesophagus and left tarsus. In the absence of neoplasia or bacteraemia, a syndrome similar to Sweet's Syndrome should be considered as a differential diagnosis in dogs with cutaneous and extracutaneous neutrophilic infiltrates.

All-purpose veterinary education: a personal perspective

The Recognition Lecture is an annual honor awarded by the Association of American Veterinary Medical Colleges (AAVMC) to an individual whose leadership and vision have made significant contributions to academic veterinary medicine and the veterinary profession. In 2011, this prestigious honor was awarded to Dr. Peter Eyre, Dean Emeritus of the Virginia-Maryland Regional College of Veterinary Medicine (VMRCVM). Dr. Eyre is a fierce advocate for veterinary medical education, with a clear vision of its value in ensuring that veterinarians are well positioned to meet societal needs. Dr. Eyre possesses an international perspective regarding the challenges and problems facing veterinary medical education and has a keen eye for getting to the heart of these challenges. He is known to ask hard questions and propose difficult choices. Dr. Eyre received his undergraduate veterinary degree (BVMS), bachelor of science degree, and PhD from the University of Edinburgh. He was Lecturer in Pharmacology at the Royal (Dick) School of Veterinary Studies for seven years before joining the faculty of the University of Guelph's Ontario Veterinary College, where he was Chair of the Department of Biomedical Sciences and Associate Director of the Canadian Centre for Toxicology. Dr. Eyre was appointed Dean of the VMRCVM in 1985, where he established the Center for Government and Corporate Veterinary Medicine in 1989. After retiring in 2003, he was named Interim Dean of the University of Calgary's new veterinary school. Among his many awards are the Norden Distinguished Teacher Award and the Sigma Psi Excellence in Research Award. In 2008 the American Veterinary Medical Association (AVMA) honored him with the President's Award, and in 2010 the University of Edinburgh awarded him the honorary degree of Doctor of Veterinary Medicine and Surgery. The Peter Eyre Student Leadership Award at the VMRCVM and the Peter Eyre Prize in Pharmacology at the University of Guelph are both named in his honor. He is a past president of the AAVMC, a fellow and former board member of the American Academy of Veterinary Pharmacology and Therapeutics, and a former member of the AVMA Legislative Advisory Committee. In the following article, Dr. Eyre offers his insights on the current debate about the future of veterinary medical education.     

Remembrances of Jacques Jenny, DrMedVet 1917–1971

Editor's note : The holding of the 19th Annual Meeting of the American College of Veterinary Surgeons in Philadelphia in conjunction with the Centennial Celebration of the School of Veterinary Medicine of the University of Pennsylvania provides an opportunity for reflection. Dr. Jacques Jenny, Professor of Orthopedic Surgery at the School, was Chairman of the Organizing Committee that gave rise to the American College of Veterinary Surgeons on December 16,1965, and was elected as first President of the College. The solid foundation and high ideals that the Organizing Committee established are in large part responsible for the success of the College. Dr. Jenny died on November 20, 1971. Those of us fortunate to have known him personally realize the immense gap that his premature death left. For those that did not know him, I hope that this article permits some appreciation of the contributions of Dr. Jenny the comparative orthopedic surgeon, as well as of the very special human qualities of Jacques Jenny the man. The first author, Dr. Mark Allam, was Professor of Surgery and Dean of the School of Veterinary Medicine during most of Dr. Jenny's career at the University of Pennsylvania, and was the first Chairman of the Board of Regents of the American College of Veterinary Surgeons. The second author, Dr. David Nunamaker, is the first holder of the Jacques Jenny Professorship in Veterinary Orthopedics at the University of Pennsylvania.     

New developments in veterinary education in the republic of Azerbaijan

After the collapse of the Soviet Union in 1991, the agrarian sector in the former member states fell into a steep decline, and veterinary training and education came to a standstill. Before the collapse, veterinary care was free, but thereafter few could afford to pay for the services of a veterinarian. Veterinary science became an unpopular study and attracted less motivated students. However, some veterinarians started Private Veterinary Units (PVU) and became successful. It will take time for veterinary training and education to catch up with modern developments. In the meantime, the establishment of a Private Veterinary Unit connected to the Veterinary Faculty could play an important role in accelerating the availability of competent veterinarians.
