Myasthenia Gravis in the Cat     

Richard J. Joseph DVM    Joseph M. Carrillo DVM  Vanda A. Lennon MD  PhD 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1988,2(2):75-79

Myasthenia gravis (MG) was diagnosed in four cats--one had an apparently congenital form and three had the acquired autoimmune form. All four cats were examined because of episodes of weakness including gait abnormalities, voice change, neck ventroflexion, and regurgitation. Palpebral reflexes were absent in all cats. Administration of edrophonium chloride resulted in transient resolution of clinical signs in all four cats. Three cats were tested for the presence of serum autoantibodies against acetylcholine receptor (AChR) by radioimmunoassay. Two cats with acquired MG had anti-AChR antibody titers of 10.5 and 96.8 nmol/l (normal, less than or equal to 0.03 nmol/l). Antibodies were not detected in the cat with presumptive congenital MG. All four cats were treated with pyridostigmine bromide. Two cats with acquired MG were euthanatized because of clinical deterioration. The third cat with acquired MG has been asymptomatic since 2 months after diagnosis. The cat with presumed congenital MG is alive 3 years after diagnosis.  相似文献   

Tumor-Associated Erythrocytosis in a Dog With Nasal Fibrosarcoma     

C. G. Couto DVM    R. J. Boudrieau DVM  E. D. Zanjani MD  PhD 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1989,3(3):183-185

Erythrocytosis (hematocrit, 79%) was diagnosed in an 8-year-old, neutered female, mixed-breed dog with an intranasal fibrosarcoma. Both serum and tumor erythropoietin (Ep) activities were elevated, as determined by the polycythemic exhypoxic mouse model, and the Ep activity was neutralized in that model by rabbit anti-Ep antibodies. Tumor resection normalized the hematocrit.  相似文献   

Neuroendocrine carcinoma of the gallbladder in a dog

A 9-year-old Bullmastiff with hematemesis was determined to have primary neuroendocrine carcinoma of the gallbladder. Despite the dismal prognosis when these unusual tumors are located in the liver, the hematemesis resolved, and there was no obvious tumor regrowth in this dog 10 months after cholecystectomy.  相似文献   

MAGNETIC RESONANCE IMAGING OF THE EQUINE FOOT   总被引：1，自引：1，他引：0

The purpose of this study was to assess the ability of magnetic resonance imaging to depict abnormalities of the equine foot. MRI was performed on isolated limbs which had lesions of the foot. These images were made in 3 perpendicular planes (sagittal, transverse and frontal) using a T1 weighted sequence and were 5mm thick. Images accurately depicted normal and pathologic structures in the foot and proved to be very precise for documenting degenerative joint disease, navicular disease and laminitis lesions. This preliminary study demonstrates the considerable potential of MRI in the diagnosis of locomotor problems in the horse.  相似文献   

Bluetongue and Douglas virus activity in New South Wales in 1989: further evidence for long-distance dispersal of the biting midge Culicoides brevitarsis   总被引：1，自引：0，他引：1  

MD MURRAY  PD KIRKLAND† 《Australian veterinary journal》1995,72(2):56-57

SUMMARY: Infection of cattle with bluetongue and Douglas viruses was detected on the central and southern coast of New South Wales from January to April 1989. Bluetongue virus infection was found well south of areas of expected occurrence. Evidence is presented to support wind-borne dispersal of infected vectors, Culicoides brevitarsis , southwards from the Hunter Valley.  相似文献   

Complete Heart Block in a Dog Seropositive for Borrelia burgdorferi: Similarity to Human Lyme Carditis   总被引：4，自引：0，他引：4

Lyme disease has been recognized in humans since 1975 when it was associated with an outbreak of oligoarthritis in children in Lyme, Connecticut. Erythema chronicum migrans (ECM) is a clinical marker for the human disease, which usually appears within 3 to 32 days after an infected tick bite. Lyme disease is caused by spirochete, Borrelia burgdorferi, which is vectored by the hard ticks Ixodes dammini or Ixodes pacificus in the United States. In humans, Lyme disease has been found to cause a variety of clinical syndromes including cardiopathy, neuropathy, dermatopathy, and arthropathy. Human Lyme carditis is characterized by varying degrees of atrioventricular (AV) heart block that usually resolve regardless of therapy. Lyme disease has been reported in the dog as an arthropathy. This article reports a case of complete heart block and myocarditis in a dog with a positive titer for B burgdorferi, in which clinical and pathologic findings were similar to those seen in human Lyme myocarditis.  相似文献   

CEREBRAL VENTRICULAR SIZE IN DEVELOPING NORMAL KITTENS MEASURED BY ULTRASONOGRAPHY     

Karin  Hultin Jäderlund  DVM  Kerstin  Hansson  DVM  Anna-Lena  Berg  DVM  pHd  Anders  Sjöström  MD  pHd  Kristina  Narfström  DVM  PHD 《Veterinary radiology & ultrasound》2003,44(5):581-588

To evaluate the age of fontanelle closure of normal kittens and the size of their lateral ventricles, 50 ultrasonographic examinations using the bregmatic fontanelle as an acoustic window were made. Seven kittens, laboratory animals, were included in the study. To verify the location of the lateral ventricle, two of the kittens were sacrificed as neonates. In one of them ink was injected prior to autopsy into one lateral ventricle under sonographic guidance. In a longitudinal study of five of the kittens, the skull depth and the depth of the central part of the lateral ventricle reproduced in a longitudinal view could be measured up to the age of about 5 months. During that period, the skull depth increased from a median value of 1.95 cm (1.92-1.98) in a seven-day-old cat to 2.58 cm (2.52-2.59) in a 154-day-old cat, while the afore-mentioned ventricle values increased from 0.3 mm to 1.1 mm.  相似文献   

Evaluation of the Cranial Rectus Abdominus Muscle Pedicle Flap as a Blood Supply for the Caudal Superficial Epigastric Skin Flap in Dogs     

DANIEL A. DEGNER DVM    RICHARD WALSHAW BVMS  Diplomate ACVS    STEVE P. ARNOCZKY DVM  MS  Diplomate ACVS    RICK J. SMITH MD    JON S. PATTERSON DVM  PhD  Diplomate ACVP    LISA A. DEGNER DVM    ANNICK HAMAIDE DVM  DIANA ROSENSTEIN DVM 《Veterinary surgery : VS》1996,25(4):292-299

This study evaluates the cranial rectus abdominus muscle pedicle flap as the sole blood supply for the caudal superficial epigastric skin flap. This flap was composed of a cranially based rectus abdominus muscle pedicle flap that was attached to the caudal superficial epigastric island skin flap (including mammary glands 2 to 5) via the pudendoepigastric trunk. Selective angiography of the cranial epigastric artery in eight cadaver dogs proved that the arterial vasculature in the cranial rectus abdominus was contiguous with that in the caudal superficial epigastric skin flap. In the live dog study, three of six of the flaps failed because of venous insufficiency. Necrosis of mammary gland 2 occurred in two of six flaps. One of six flaps survived with the exception of the cranial most aspect of mammary gland 2. Angiography of the cranial epigastric artery proved that arterial blood supply to these flaps was intact. Histological evaluation of the failed flaps showed full-thickness necrosis of the skin and subcutaneous tissues, the presence of severe congestion, and venous thrombosis. Retrograde venous blood flow through the flap was inconsistent, and hence resulted in failure of this myocutaneous flap. Use of this flap for clinical wound reconstruction cannot be recommended.  相似文献   

Postcaval Thrombosis and Delayed Shunt Migration After Pleuro-Peritoneal Venous Shunting for Concurrent Chylothorax and Chylous Ascites in a Dog     

STEVEN L. PETERSON DVM  MD  Diplomate ACVS 《Veterinary surgery : VS》1996,25(3):228-230

Simultaneous chylothorax and chylous ascites related to intestinal lymphangiectasia was diagnosed in a 4-year-old spayed female dog. Palliative pleural and peritoneal drainage was accomplished by placement of fenestrated silastic sheeting into surgically created diaphragmatic defects, and implantation of a pleuro-peritoneal venous shunt. The immediate postoperative period was complicated by acute renal failure secondary to postcaval thrombosis originating at the site of placement of the efferent pump catheter and extending to the level of the renal veins. Rapid resolution of this complication was accomplished with systemic anticoagulation. Clinical signs related to fluid accumulation resolved for 10 weeks after which acute decompensation occurred and the dog was euthanatized. Postmortem examination showed that reaccumulation of fluid was associated with migration of the efferent limb of the shunt from the caudal vena cava.  相似文献
