Epidermoid cyst of the ileum in a miniature dachshund dog

A 13-year-old castrated male miniature dachshund dog was presented with chronic vomiting and diarrhea. Contrast radiography and surgical exploration revealed an ileal cyst, which was excised. A diagnosis of epidermoid cyst was made from a combination of the clinical findings and histological examination of the surgical specimen.     

Phenotypic intersex (female pseudohermaphroditism) in a dachshund dog

A male miniature rough-haired dachshund, presented with episodic haematuria, was found to be a female pseudohermaphrodite. A littermate also had an abnormality of the urogenital tract and their dam had received a progesterone implant during pregnancy. Chromosome analysis of the intersex revealed XX/XY mosaicism in certain tissues.     

Pneumocystis carinii in the miniature dachshund: Case report and literature review

This article reviews Pneumocystis carinii and presents four cases in the miniature dachshund. The cases presented with hyperpnoea, tachy-pnoea and exercise intolerance. There were also clinical signs suggestive of immune incompetence in all the dogs. P carinii pneumonia was diagnosed in all four cases on transtracheal aspirate cytology. Immunological studies showed low globulin levels on serum electrophoresis, decreased lymphoblast transformation response (in the two cases that were tested) and a deficiency of immunoglobulins A, G and M. Light and electron microscopy as well as anti-canine immunoglobulin G immunoperoxidase staining studies were performed on one case which had died because of the disease. From these four cases, it appears that P carinii pneumonia in the miniature dachshund may be the result of an immunodeficiency. It does not, however, appear to be a classic primary severe combined immunodeficiency syndrome as the dogs appeared to respond to treatment, did not show growth failure and did not manifest overwhelming commensurate bacterial infections.     

Cervical chondroid chordoma in a standard dachshund: a case report

A ten-year-old male standard dachshund was presented with a history of neck pain and progressive gait disturbances. Following a neurological examination and diagnostic imaging, including CT, a neoplastic lesion involving the third and fourth cervical vertebrae was suspected. The lesion included an extradural mass on the right side of the spinal canal causing a local compression of the cervical cord. Surgery, using a modified dorsal laminectomy procedure, was performed in order to decompress the cervical spinal cord. Histopathological examination of the extradural mass indicated that the tumour was a chondroid chordoma. Following discharge, the quality of life for the dog was very good for a sustained period, but clinical signs recurred at 22 months. The dog was euthanased 25 months post-surgery. On post-mortem examination, a regrowth of neoplastic tissue was found to have infiltrated the bone and spinal cord at C3-C4. This is the first report to show that palliative surgery can offer successful long-lasting treatment of chondroid chordoma of the cervical spine in the dog.     

A case of hypospadias in a dog

: This clinical case report described a three-month-old mongrel dog that had the urethral orifice opening 3 cm from the tip of the penis and lacked a completely formed preputial sheath. It was presented to the clinic with an exposed penile shaft that was dry. The dog had urinary incontinence that was not of neurological origin. It also had unilateral agenesis of the right testicle. The preputial sheath was successfully reconstructed. Urinary incontinence stopped soon after surgery, suggesting that it had been probably due to an ascending urethritis. A large preputial opening was left because of the location of the urethral opening.     

Home-care treatment of swimmer syndrome in a miniature schnauzer dog

A 50-day-old, female miniature schnauzer dog was presented for astasia, dorsoventral flattening of the thorax, hypoplasia of hind-limb muscles, stiffness of hind-limb joints, paddling leg motion, and panting. The dog was diagnosed with swimmers syndrome. The dog recovered completely following 40 days of home-care treatment that involved environmental and nutritional management along with intensive physiotherapy.     

Hairy shaker disease of lambs

A serological survey of 213 randomly chosen dairy farm residents in the Manawatu showed that 66 (34%) of the people who milked cows had leptospiral titres ≤ 1:24 by the Microscopic Agglutination Test. Forty-eight (72.7%) of these people had titres to hardjo, while 29 (43.9%) had titres to pomona. Dual hardjo/pomona titres occurred in 12 people. Ballum and Copenhageni accounted for 8% of the titres found. Women milkers and farm residents who did not milk were all serologically negative. A third of the seropositive milkers had a history of clinical leptospirosis. Other factors which significantly correlated with leptospiral titres included the time spent in the dairy shed during milking, the wearing of shorts, the keeping of pigs for sale, and the number of years the individual had been working on a dairy farm. The type of milking shed and the size of the herd were interrelated and both showed strong trends towards a correlation with serological prevalence.     

A comparison of diagnostic tests for hairy shaker disease

Abstract

Extract

From 1982 to 1988, the virus culture interference assay was used by the Animal Health Laboratory Network as a diagnostic test for hairy shaker (HS) disease (known as border disease in the United Kingdom). However, this assay is slow and relatively expensive, and in some studies of the prevalence of HS disease it gave inexplicably high rates of 28–33% ⁽¹⁾ Orr, MB and Montgomery, RH. 1983.

The present project was designed to compare the virus culture interference test with an immunoperoxidase (IPX) method and an antigen capture ELISA for the detection of HS virus.
